Description

ATTACHABLE EXTENDABLE AND RETRACTABLE

EARPIECE ASSEMBLY

Background of the Invention

1. Field of the Invention

The present invention relates generally to extendable and retractable earpieces for mobile sound and communication devices and for casings for such devices, and more particularly to an extendable and retractable earpiece assembly permanently attached directly to the mobile device in one embodiment, removably attached directly to the mobile device in other embodiments, and removably attached to or integrally formed with a protective casing for protecting a mobile electronic device in further embodiments.

2. Description of the State of the Art

Portable sound and communication devices deliver sound waves through either a built in speaker unit or a pair of earpieces adapted to be electrically connected to and removed from the device. While a speaker is a practical feature for a portable communication device, portable sound systems designed to deliver a user's musical selections over a period of time generally require connection of at least one headset earpiece, or earpieces per se, to the portable device to convey the sound to the user in private, and without disturbing those nearby the user. Also, many portable

communication devices that have a built-in speaker system also have a socket for receiving an earpiece connection jack or plug.

Currently, most if not all portable sound devices, and many portable

communication devices, are used with headsets or earpieces. For example, portable communication device users rely on headsets or earpieces for convenience in multi- tasking. Such headsets and earpieces, and associated wires, however, when not in use, extend and dangle from the mobile device, allowing the wires, headset and/or earpieces to become ensnared on a nearby object, such as the user's clothing, and to rip out of the device causing damage to the headset or earpieces and wires, or both. Replacement of such damaged parts can be costly.

Additionally, most users of portable sound and communication devices are required to carry at least three separate pieces: a carrying case, a headset or earpieces, and the sound or communication device. Locating and carrying three separate pieces is often frustrating and time consuming. Additionally, certain scientific studies have suggested that the extended use of cell phone or blue tooth wireless headset devices, when the cell phone or blue tooth wireless headset device is placed directly adjacent to one's ear can result in undesirable health problems, such as tumors and cancer, not the least of which is known as cell phone elbow with cell phones. Some users of blue tooth wireless headset devices or cell phones in close proximity to the ear have also reported increased headaches.

A common accessory furnished with mobile communication and sound devices is a pliable plastic or rubber casing that extends tightly around the outer body of the device, with apertures in the casing allowing the user to access the controls, inputs, outputs, and displays of the communication or sound device. The plastic or rubber tightly fitting casing protects the integrity of the mobile device if the device is accidentally dropped or flung into contact with a hard surface by absorbing potentially disabling shock forces before they reach the mobile device. Presently available recharging units and carrying cases for portable sound and communication devices include assemblies to hold earpiece cables around a spool attached to the carrying case or recharging unit. See, for example, U.S. Patent

Publications No. 2005/0116684; 2005/0255898; and 2007/0293288. The prior art also includes stand alone headset cable reel assemblies that attach to the cable itself. These devices add yet another separate component for a user of a portable sound or communication device to deal with. For example, see Patent Publication No.

2001/0035242. Furthermore, presently available casings are used to protect mobile electronic devices from contact with external elements to prevent scratches, dents, and even protect from contact with water. See, for example, U.S. Patent Publications No. 2005/0140255 Al; 2008/0039161 Al; and U.S. Patent No. 6,078,792.

While minimizing the amount of accessories needed for a mobile electronic device, the present device also minimizes the length of a connector plug cable and earpiece cables exposed to the environment during use, reducing potential damage to the mobile electronic device as well as injury to the user. This is particularly advantageous for children carrying backpacks and sports duffle bags who desire to listen to music or speak with their friends on the phone at the same time. This is also advantageous to adults hurrying to appointments while carrying a brief case or purse while speaking on the phone.

None of the aforesaid prior devices provide a combined integral extendable and retractable earpiece cable reel assembly that attaches directly to a portable sound or communication device, or that can be removably attached directly to a portable sound or communication device. Further, none of the aforesaid prior devices provide a combined integral extendable and retractable earpiece cable reel assembly that is integrally formed with or removably attached to a tight fitting protective casing for a portable sound or communication device.

Summary of the Invention

The present invention provides, in one embodiment, a carrying clip allowing a user to attach a mobile sound or communication device such as a cell phone, sound pod, PDA, pager, etc. to the user's belt, pocket, handbag, backpack or other personally worn or carried item. The carrying clip includes a housing portion in which is located extendable and retractable earpieces. Each earpiece is attached to an earpiece cable that is electrically connected to the earpiece at one end, and to a jack plug at an opposite end. The jack plug is designed to be inserted into the outlet portal of the mobile device. The carrying clip in one embodiment has a semi-permanent adhesive on one surface of a plate, with the adhesive removably attaching the plate to the rear of the mobile device. This embodiment of the invention eliminates carrying three separate items: the cell phone or sound pod, carrying case, and headset or earpieces. The housing for the retractable earpiece cables could be permanently fixed to the plate, or could be removably attached to the plate.

The clip assembly may also include a separate small adhesive-backed hook-and- loop fastening device to attach the clip to the dashboard of a car, or to another solid surface.

Additional embodiments of the present invention provide a rear plate adapted to be fixedly attached to the rear of the mobile communication or sound device, and a forward plate assembly that is removably attached to the rear plate. The forward plate assembly includes a cable reel assembly into which the earpiece cables are retracted when the mobile device is not in use. The removable forward plate assembly allows the mobile communication or sound device to be installed in a docking station without interference from the forward plate and cable reel assembly.

The present invention also provides a further embodiment in which the carrying clip fixedly or pivotally attaches to a casing, which casing tightly encases the mobile electronic device. The casing is made of rubber, plastic, or other suitable materials, and is configured so that the interior of the casing has substantially the same dimensions as the exterior of the electronic mobile device. The casing includes apertures for the controls and input and output ports of the mobile electronic device, as well as an aperture for each electronic display. The casing, in an embodiment, also includes an integrally formed reel housing portion in which the extendable and retractable earpiece cables are located. In an additional embodiment, the earpiece cable reel housing is removably attached to the casing. Each earpiece is attached to an earpiece cable that is electrically connected to the earpiece at one end, and to a connector plug at an opposite end. The earpiece cables and connector plug cables penetrate the reel housing through earpiece cable apertures and connector plug apertures, respectively. The connector plug is designed to be inserted into the outlet portal of the mobile electronic device. The housing in the additional embodiment can be removed for service or replacement, and reattached again to the casing's posterior side, opposite the casing aperture for the electronic display. The reel housing portion in another embodiment is integrally formed with the casing on the casing's posterior side, opposite the casing aperture for the electronic display. These embodiments of the invention eliminate carrying three separate items: the cell phone or sound pod, carrying case, and headset or earpieces.

The present invention, in one embodiment, provides a retractable headset or earpiece cable assembly mounted on a plate. The plate is attached directly to the rear of a mobile communications or sound device, and the cable assembly is extendable from and retractable into a reel housing mounted on the plate. A clip assembly is also mounted on the plate for attaching the plate and mobile device to the belt, pocket, backpack or strap worn or supported by the user. The invention allows a user to carry only a single item that includes the mobile communication or sound device, retractable headset or earpiece and cables, and clip-on assembly in lieu of transporting several pieces to achieve the same results provided by the present invention. The user benefits from the convenience and ease of transporting and using his or her mobile communication or sound device, and having an integral clip-on unit and cable reel assembly mounted directly on the mobile device to prevent the cables from becoming tangled or hanging loose when the portable device is not being used.

Referring to the embodiment of Figs. 1 and 2, the extendable and retractable earpiece cable and attachment clip assembly of the present invention is generally designated by the numeral 10. The assembly 10 comprises a relatively thin flat plate 12 having forward and back surfaces 14, 16 respectively. As seen in Fig. 1, back surface 14 of plate 12 is adapted to be fixed directly to the rear of mobile sound or communication device 18 by means of adhesive, hook and loop fasteners, or other attachment means as are known in the art.

If the mobile device 18 is of the type that is impermeable to, or its operation is not affected by, magnetic waves, the assembly 10 could be magnetically attached to the dash of a vehicle for storage when not in use. In this embodiment (not shown) a separate permanent magnet is attached to the dash that would attract and secure the metal of clip 20 to the dash. In another embodiment (not shown), where a hollow cable reel assembly housing 26, described below, is located on the forward surface 14 of plate 12 (Figs. 1, 2) and the clip 20 extends around the sides of housing 26, then housing 26 can be attached directly to the permanent magnet on the vehicle dash when the device 10 is not in use.

An attachment clip 20 is pivotally attached to forwarded surface 14 of plate 12 by pivot pins 22 extending through a pair of brackets 24. Brackets 24 are each attached to or integral with the forward surface 14 of plate 12. Clip 20 is biased to the closed position against forward surface 14 by means of a coil spring assembly, not shown. As will be explained, attachment clip 20 is adapted to removably engage a belt, strap or other item worn by a user of mobile device 18.

The hollow cable reel assembly housing 26 is formed on or attached to forward surface 14 of plate 12. A retractable and extendable cable reel assembly is located inside reel housing 26. As seen in Fig. 2, reel housing 26 includes at least one aperture 28 through which earpiece cables 30, 32 extend. Each cable 30, 32 is electrically connected to an earpiece 34, as seen in Figs. 1 and 2. Cables 30, 32 are attached at their respective ends opposite earpieces 34 to a retractable and extendable reel mechanism inside reel housing 26, that allows cables 30, 32 to be manually extended from housing 26 as the user places earpieces 34 in his or her ears.

Referring to Fig. 2A, reel housing 26 includes a top part 108 that mates with bottom part 110 to form hollow reel housing 26. A shaft 112 is attached to and extends outward from bottom part 110, and a slit 114 is formed in the upper portion of shaft 112. A cable reel 116 is located in reel housing 26, and a coil plate spring 118 is located in an open circular wall portion 120 of reel 116. When reel 116 is assembled in reel housing 26, an end 122 of spring 118 fits into slit 114 of shaft 112, holding one end of spring 118 against rotation. The other end of spring 118 is firmly attached to wall portion 120 of reel 116.

Reel 116 includes a plurality of angled ratchet teeth 124 mounted on a rim of the reel. A release button 126 has a stopper and release arm 128, and the release button 126 is pivotally mounted to a shaft 130 attached to bottom part 110 of reel housing 26. The underside of outer end of stopper and release arm 128 includes a stop member (not shown) that is adapted to engage ratchet teeth 124 and allow rotation of cable reel 116 in the clockwise direction only as viewed in Fig. 2A. When release button 126 is pivoted, and arm 128 is moved away from engagement with ratchet teeth 124, spring 118 will rotate reel 116 in a counter-clockwise direction, as will be explained. A small spring 132 engages a side wall of reel housing 26, and biases stopper and release arm 128 into engagement with ratchet teeth 124.

In the embodiment illustrated in Fig. 2A, a plurality of concentric conductive rings 134a, b, c, d are located on the interior of bottom part 110 of reel housing 26. A printed circuit board 136 is positioned next to bottom part 110, and includes a plurality of concentric conductive rings 134a-d. Each of the conductive rings 134a-d are electrically connected to cable 36 and jack plug 40 (Fig. 1) by solder points 138a-d (Fig. 2A). In the illustrated embodiment, four spring wiper contacts (not shown) are attached to reel 116 and are aligned such that when reel 116 rotates, the spring wiper contacts remain in constant contact with a corresponding conductive ring 134a-d. The four wires in both earpiece cables 30, 32, are each connected to one of the spring wiper contacts on reel 116. Release button 126 extends through an opening 140 in reel housing 26, making release button 126 accessible to a user.

When a user desires to extract earpiece cables 30, 32 from reel housing 26, the user pulls on earpieces 34 (Fig. 1) using a slight tension force. The stop member (not shown) on the underside of stopper and release arm 128 glides over ratchet teeth 124 as reel 116 rotates without engaging the ratchet teeth. Simultaneously, spring 118 is wound, thus storing kinetic energy. When a sufficient length of earpiece cable 30, 32 has been extracted from reel housing 26, tension on the cables is released, and the stop member engages one of the ratchet teeth 124, preventing reverse rotation of cable reel 116. Reel 116 can be fixed at any point on the rotation of reel 116, allowing the user to extract any suitable length of earpiece cable 30, 32 and have the earpiece cable fixed at that extracted length until release button 126 is pushed inward.

When the user desires to retract earpiece cables 30, 32 into reel housing 26, finger pressure is applied to release button 126, which pivots stopper and release arm 128 out of engagement with the ratchet teeth 124. The kinetic energy stored in spring 118 is released, rotating reel 116 in an opposite direction, thus rewinding cable wires 30, 32 onto reel 116. At all times during the extraction or retraction of earpiece cables 30, 32 relative to reel housing 26, the earpieces 34 remain electrically connected to solder points 138a-d and to cable jack plug 40 (Fig. 1). Cables 30, 32 are prevented from being retracted fully inside of reel housing 26 since the outer diameters of earpieces 34 at the point where they attach to cables 30, 32, respectively, are larger than the inner diameters of apertures 28. The concentric ring-spring wiper contact, spring operated reel and lock-release designs illustrated in Fig. 2A and described above are well known in the field of electrical and mechanical design. However, the described retractable earpiece cable structure has not been used previously in a retractable and releasable earpiece cable assembly that is attached directly to, or removably attached directly to, a mobile communication or sound device.

The ends of cables 30, 32 opposite earpieces 34 as described above, are electrically connected through solder points 138a-d to a cable 36 extending from an aperture 38 in reel housing 26. The terminus end of cable 36 includes a jack plug 40 that is adapted to be inserted into the sound output portal 42 of the mobile device 18. For convenience, the cable 36 may be a self-coiling cable that is extended when plug 40 is inserted into portal 42.

To operate the retractable earpiece cable assembly 10 illustrated in Figs. 1 and 2, a user first attaches the back surface 16 of plate 12 to the rear of mobile device 18 with an adhesive, semi-permanent adhesive, hook-and-loop fastener, or other suitable fastening device. If feasible, a magnetic fastener may be used to attach plate 12 to the rear of mobile device 18. Jack plug 40 is then inserted into sound output portal 42 of mobile device 18, establishing an electrical connection through cables 30, 32 and cable 36 between earpieces 34 and the sound output system embedded in mobile device 18.

The user then attaches assembly 10 to his or her belt, strap, backpack, item of clothing, etc., by pressing on upper portion 44 of attachment clip 20 (Figs. 1, 2) and moving the bottom of attachment clip 20 away from plate 12. When suitably attached to the apparel or accessory item worn by the user, upper portion 44 of clip 20 is released, and attachment clip 20 holds the plate 12 and mobile device 18 securely to the user's apparel or accessory item. If necessary or desired, the mobile device 18 is activated to be able to receive and/or send electronic impulses that are transformed into sound at earpieces 34.

The user then manually grasps earpieces 34 and applies a tension or pulling force that extracts cables 30, 32 out of reel housing 26 through apertures 28. As cables 30, 32 are extracted from reel housing 26, The spring 118 acting on the cable reel inside reel housing 26 is wound, applying a tension force on the ends of cables 30, 32 extending around the cable reel 116. Upon extracting sufficient cable 30, 32 from reel housing 26 to allow the user to insert one earpiece 34 in each ear, the retraction process is halted, and the automatic reel brake mechanism shown in Fig. 2A, is activated to brake the cables 30, 32 against being retracted back into the housing 26 until the user has completed using mobile device 18.

To retract the cables 30, 32 back into reel housing 26, the user removes the earpieces 34 from the ears, and applies a brief tug or tension force on the cables 30, 32. The spring operated reel 116 inside housing 26 is released as explained above, and the energy stored in the reel spring 118 when the cables 30, 32 were extracted from reel housing 26, rotates the reel and draws cables 30, 32 back onto reel 116 and into housing 26 until each earpiece abuts housing 26 adjacent an aperture 28. It is not necessary to disengage jack plug 40 from portal 42 when the mobile device 18 is no longer being used.

Thus, as seen in Figs. 1, 2 and 2A, an integral retractable earpiece cable and supporting attachment device 10 is provided in a single unit that attaches to and remains with a mobile communication device. The user need not carry separate headphones or earpieces and separate attachment devices or pouches when transporting and/or using their mobile sound or communication device. The invention described above and shown in Figs. 1, 2 and 2A provides the user of the mobile device 18 with the convenience of having the earpieces and attachment apparatus for their mobile device as a single unit, thus providing ease of use and aiding in preventing the loss of individual components.

A further embodiment of the present invention is illustrated in Figs. 3-5. This embodiment allows removal of a front plate assembly of the present invention when the user desires to insert the mobile device 18 into a docking station receptacle. As seen in Figs. 3 and 5, rear plate 46 forms part of retractable earpiece cable and clip on assembly 10. The rear flat surface 48 of rear plate 46 is attached by adhesive, hook and loop fasteners, or other fastening devices that are known in the art to the rear of mobile device 18. The lateral edges of rear plate 46 are formed into tubular members 50 each defining a hollow channel 52 extending the length of tubular members 50. Each channel 52 is open as shown at 54, such that the portion of rear plate 46 forming tubular members 50 extends approximately 300 to 340 degrees, leaving a longitudinal opening along the vertical length of each channel 52. In the embodiment of Figs. 3-5, an aperture 56 is located adjacent the lower extent of each tubular member 50.

Fig. 4 illustrates the reel housing 26 attached to or formed with the front side of forward plate 58. A pair of cables 30, 32 extend from reel housing 26 as described above with reference to the embodiment of Figs. 1, 2 and 2A. Reel housing 26 includes the retractable and extendable cable reel assembly. Earpieces 34 are also connected at one end to cables 30, 32 similar to the embodiment of Figs. 1 and 2. Also, attachment clip 20 is pivotally attached to forward plate 58.

Each side edge of forward plate 58 includes a tube member 60, 62 having an outer dimension slightly less than the inner diameter of hollow channel 52 of tubular members 50 (Fig. 3). In the illustrated embodiment, tube members 60, 62 are solid, but could be formed in the configuration of hollow tubes if desired. At the lower end of each tube member 60, 62, a spring loaded latch pin 64, 66 is mounted to the tube member for lateral movement toward and away from a respective tube member 60, 62. A spring (not shown) biases each latch pin 64, 66 in an outward direction.

Fig. 5 is a top view of the retractable earpiece cable and attachment clip assembly 10 of the second embodiment of the present invention, showing forward plate

58 slidably and removeably mounted to rear plate 46 (Fig. 3). As seen in Fig. 5, rear plate 46 is attached to mobile device 18 as previously described. Forward plate 58 is assembled on rear plate 46 by sliding tube members 60, 62 along hollow channels 52 of rear plate 46 until latch pins 64, 66 (Fig. 4) extend outward into apertures 56 of tubular members 50 (Fig. 3) and provide a detent locking mechanism to lock forward plate 58 into its proper position adjacent rear plate 46. In this locked position, forward plate 58 extends through openings 54 as illustrated in Fig. 5.

To disengage forward plate 58 from rear plate 46, spring biased latch pins 64, 66 are pushed inward by thumb or finger pressure by the user, until each latch pin 64, 66 has been substantially withdrawn from a corresponding aperture 56. The forward plate 58 is then moved upward to separate the forward plate from rear plate 46. In this configuration, the mobile device 18, with rear plate 46 still attached, can be mounted into a docking station, recharging station, or other device as desired by the user. In an embodiment of the present invention, rear plate 46 is made of a strong but flexible material, allowing tubular members 50 to compress to a somewhat flattened position.

Figs. 6 and 7 illustrate an embodiment of the retractable earpiece cable and attachment clip assembly 10 of the present invention wherein a flexible member such as a living hinge construction replaces the detent latch mechanism of Figs. 3 and 4 to lock forward plate 58 to rear plate 46. Referring to Fig. 6, a slot 68 is formed in the walls of each tubular member 50 of the embodiment of rear plate 46 shown in Fig. 3.

Fig. 7 is a detail view illustrating a flexible hinge latching mechanism to removably secure forward plate 58 to rear plate 46. In this embodiment, each tube member 60, 62 extending longitudinally on either side of forward plate 58 includes a flexible arm 70 attached at its upper extent, or preferably formed integral with, tube members 60, 62. A first space 72 lies between flexible arm 70 and a wall portion 74 of each tube member. A second space 76 lies between the bottom of flexible arm 70 and horizontally extending portion 78 of the tube members 60, 62. As seen in Fig. 7, flexible arm 70 is capable of pivotal movement in space 72.

A horizontally extending flange 80 is formed at the bottom of flexible arm 70. Flange 80 includes a flat upper surface 82, a slanted lower surface 84, and a flat frontal surface 86. In its quiescent position shown in Fig. 7, flange 80 extends outward through slot 68 in tubular member 50 such that flat upper surface 82 of flange 80 abuts the upper surface 104 of slot 68, thereby keeping tube members 60, 62, and forward plate 58 from moving upward relative to rear plate 46, as will be explained. A further embodiment of a latching mechanism to secure the forward plate to the rear plate is illustrated in Figs. 8-10A and B. Referring to Fig. 8, forward plate 88 is configured similar to flat plate 12 shown in Figs. 1 and 2, with reel housing 26 formed with or attached to forward plate 88 and cables 30, 32 retractably extending from reel housing 26, and attachment clip 20 also attached to forward plate 88.

In the illustrated embodiment, sets 90 of slots 92 are formed adjacent to each of the four corners of forward plate 88. Slots 92 extend through forward plate 88 and are shown as square or rectangular in shape, but can be any other shape if desired.

Fig. 9 discloses a rear plate 94 that is adapted to be mounted on the rear surface of mobile device 18 (Fig. 1). In this embodiment, rear plate 94 includes four spring-biased moveable latch mechanisms 96 that are dimensionally spaced from the lateral top and bottom edges of rear plate 94 the same as slots 92 are dimensionally spaced from the lateral, top and bottom edges of forward plate 88. As seen in Figs. 10A and B, each latch mechanism 96 includes a pair of moveable latch members 98 mounted on a slide member 99, wherein each slide member 99 is moveably disposed in a channel or on a rail (not shown) of rear plate 94 such that each latch member is slidable in the same plane as the outer surface of rear plate 94. Each latch member 98 is biased away from its adjacent latch member by a compression spring 100, or any other compression force device as is known in the art. Each latch member 98 also includes a slanted surface 102, and a groove 106 adapted to engage a rim of a slot 92 when forward plate 88 is mounted on rear plate 94, as will be described.

In operation of the embodiment shown in Figs. 3-5, the rear plate 46 is adhesively or otherwise attached to the back of mobile device 18. The tube members 60, 62 of forward plate 58 are inserted into the top of tubular members 50, and under the force of manual pressure are slid downward in hollow channels 52. When the forward plate 58 reaches the appropriate position, spring loaded latch pins 64, 66 are driven outward into an adjacent aperture 56 in each tubular member 50. This locks forward plate 58 to rear plate 46, and to the rear of mobile device 18. Jack plug 40 (Fig. 4) is then inserted into sound output portal 42 (Fig. 3) of mobile device 18, electrically connecting the sound output system of mobile device 18 to the earpiece cables 30, 32 mounted on reel 116 (Fig. 2A) inside reel housing 26, and to earpieces 34. The user then may attach the assembly 10 and mobile device 18 to an article of clothing or accessory such as a belt, backpack strap, pocket, or the like using attachment clip 20, or place assembly 10 and mobile device 18 into a pocket or handbag, or any other suitable carrying article. To listen to the sound generated by mobile device 18, a slight tension force is manually applied to earpieces 34 to extract cables 30, 32 from reel housing 26 as the cables are unwound from spring-biased reel 116 in reel housing 26. The spring 118 attached to reel 116 is wound, thus storing kinetic energy. When the tension force is removed from cables 30, 32, a slight rearward force on the cables 30, 32 causes reel locking mechanism 124, 128 to lock the cables in place in their extended position as the user inserts the earpieces into his or her ear. The mobile device 18 is then activated to provide sound to the user through the earpieces 34.

When the user is finished listening to the sounds produced by the mobile device 18, the mobile device is switched to its off position, and the earpieces are removed from the user's ears. The user then applies a brief tension pull the cables 30, 32, which releases the reel locking mechanism 124, 128 inside reel housing 26, and the cables 30, 32 are rewound on the reel 116 by the kinetic energy stored in the spring 118. The earpieces 34 are drawn to their storage position against reel housing 26, as seen in Figs. 4 and 5.

Referring to the embodiment of Figs. 3-5, if the user desires to place mobile device 18 in a docking station, jack plug 40 is withdrawn from sound output portal 42 of mobile device 18. Thumb and/or finger pressure is then applied to the portions of spring biased latch pins 64, 66, thus disengaging the latch pins from apertures 56, enabling tube members 60, 62 and forward plate 58 to be moved upward in tubular members 50 of rear plate 46. Forward plate 58, along with reel housing 26 and attachment clip 20 is removed from rear plate 46 and stored in a convenient location. Rear plate 46 remains attached to mobile device 18. Tubular members 50 are made of a relatively flexible material, permitting a certain latitude of deformation of the tubular members, if necessary, when mobile device 18 is placed in a docking station.

The embodiment shown in Figs. 6 and 7 operates with a modified latching mechanism between rear plate 46 and forward plate 58 compared to the spring loaded latch pin mechanisms 64, 66 of Figs. 3-5. Referring to Figs. 6 and 7 when tube members 60, 62 of forward plate 58 are inserted into the hollow channels 52 formed by each tubular member 50, the forward plate 58 moves downward with flat frontal surface 86 of each flange 80 slidably engaging the interior surface of a corresponding hollow channel 52, thereby pressuring the lower portion of flexible arm 70 inward into first space 72. As flat upper surface 82 of flange 80 reaches upper surface 104 of slot 68 in tubular member 50, flange 80 and flexible arm 70 are forced outward as flexible arm 70 moves to its unpressured quiescent state. In this position, as shown in Fig. 7, flat upper surface 82 of flange 80 engages upper surface 104 of slot 68, locking tube members 60, 62 and forward plate 58 to rear plate 46 and to mobile device 18. The remainder of the operation of the assembly 10 in its assembled condition is the same as that described in connection with the embodiment of Figs. 3-5 above.

To disengage forward plate 58 from rear plate 46, thumb or finger pressure is applied to flat frontal surface 86 of each flange 80 located on both tube members 60, 62 until flat upper surface 82 of each flange 80 becomes disengaged from its corresponding surface 104 of slot 68. As flange 80 is moved out of slot 68, flexible arm 70 pivots inwardly into first space 72. An upward force is then applied to forward plate 58 to remove tube members 60, 62 from hollow channels 52 until rear plate 46 and front plate 58 are separated. Front plate 58 is then stored until needed by the user.

The operation of the embodiment of the present invention shown in Figs. 8-1 OA and B is next described. As seen in Fig. 9, rear plate 94 is attached to mobile device 18 by means of adhesive, hook-and-loop fasteners, or any other suitable fastening means.

Latch members 98 project outwardly away from the surface of rear plate 94. Next, forward plate 88, with reel housing 26, earpieces 34, cables 30, 32 and attachment clip 20, is manually placed over rear plate 94 such that each pair of slots 92 are juxtaposed over a corresponding latch member 98. As forward plate 88 is pushed toward rear plate 94, an edge of each slot 92 contacts a slanted surface 102 of a latch member 98, forcing adjacent latch members to move towards each other against the force of spring 100. When forward plate 88 is in position against rear plate 94, the slots 92 rest adjacent grooves 106 (Figs. 10A and B) in each latch member 98. Springs 100 then move each slide 99 and latch member 98 outward such that the portions of forward plate 88 adjacent the slots 92 are grasped in corresponding grooves 106, and forward plate 88 is held firmly against rear plate 94.

To disengage forward plate 88 from rear plate 94, manual pressure is applied to each pair of latch members 98, forcing the latch members together against the force of springs 100. This removes the portions of forward plate 88 adjacent slots 92 from engagement with grooves 106, allowing forward plate 88 to be lifted away from rear plate 94. The forward plate 88 is then stored until needed.

Figs. 11, 12 and 13 illustrate a further embodiment of the invention shown in Figs. 3-7, wherein the attachment clip 20 is flexibly attached directly to rear plate 46 as seen in Figs. 11 and 13, whereas the attachment clip 20 is attached to forward plate 58 in the embodiment of Figs. 3-5. Like numerals in Figs. 11-13 and Figs. 3-5 are used to identify like elements, and the description of the elements of the embodiment of Figs. 1-3 above is equally applicable to the embodiment of Figs. 11-13 with the exception of the location of attachment clip 20.

In operation, the embodiment of Figs. 11-13 includes rear plate 46 attached, or removably attached, to mobile device 10 as previously described with reference to the embodiment of Figs. 3-5. In the embodiment of Figs. 11-13, forward plate 58 (Figs. 12, 13) is attached to rear plate 46 by inserting tube members 60, 62 of forward plate 58 into the bottom of hollow channels 52 formed in tubular members 50 of rear plate 46. The forward plate is then advanced upward until spring loaded latch pins 64, 66 engage apertures 56 in tubular members 50 to lock forward plate 58 in position relative to rear plate 46 (Figs. 11-13). In an alternative embodiment where the "living hinge" flange 80 (Figs. 6, 7) replaces latch pins 64, 66 (Figs. 3-5), the forward plate 58 is moved upward until flange 80 extends through slot 68, and forward plate 58 is locked in position against rear plate 46. In the embodiment of Figs. 11-13, forward plate 58 must be attached to rear plate 46 through the bottom of hollow channels 52 since the location of attachment clip 20 in this embodiment prevents the insertion of forward plate 58 and tube members 60, 62 from the top of hollow channels 52.

Several embodiments of the present invention provide a retractable earpiece cable or headset assembly in a reel housing, where the reel housing is mounted on a casing. In one embodiment, the reel housing is integrally formed with or attached to the casing. In a further embodiment, the reel housing is mounted to the casing using an attachable and detachable mounting assembly. The casing is adapted to tightly encase a mobile communications or sound device for protection of the device against shock forces, and the cable assembly is extendable from and retractable into a reel housing integrally formed with the casing. A clip assembly is also mounted on the casing for attaching the casing and mobile electronic device to a belt, pocket, backpack or strap worn or supported by the user. The invention allows a user to carry only a single item that includes the mobile communication or sound device, retractable headset or earpiece and cables, and the casing firmly attached to the mobile device, in lieu of transporting several pieces to achieve the same results provided by the present invention. The user benefits from the convenience and ease of transporting and using his or her mobile

communication or sound device, and having a clip-on unit and cable reel assembly integrally formed with or detachably mounted on the protective casing extending over portions of the mobile electronic device to prevent the cables from becoming tangled or hanging loose when the sound capabilities of the portable device are not being used. Referring to the embodiment of Figs. 14-18 and 20, the protective apparatus 210 is adapted to protect a mobile electronic device 212, and casing 214, having an integral, hollow reel housing 216, is adapted to fit tightly over portions of the mobile device 212. The reel housing 216 houses the extendable and retractable earpiece cable assembly 218 of the present invention (Fig. 15). As seen in Fig. 14, the reel housing 216 of this embodiment is integrally formed with the casing 214 of the protective apparatus 210. A carrying clip 220 is pivotally attached to the casing 214 by pivot pins 222 (Fig. 20) extending through a pair of brackets 224. Brackets 224 are each attached to or integral with the casing 214 of protective apparatus 210. Carrying clip 220 is biased to the closed position against the casing 214 by means of a coil spring assembly 226 (Fig. 20). As will be explained, carrying clip 220 is adapted to removably engage a belt, strap or other item worn by a user of mobile electronic device 212.

The hollow reel housing 216 is integrally formed with the casing 214 of the protective apparatus 210. A retractable and extendable earpiece cable reel assembly 218 (Fig. 15) is located inside reel housing 216. As seen in Fig. 14, reel housing 216 includes at least one earpiece cable aperture 228 through which earpiece cables 230 and 232 extend. Each earpiece cable 230, 232 is electrically connected to an earpiece 234, 236. Earpiece cables 230, 232 are attached at their respective ends opposite earpieces 234, 236 to a retractable and extendable reel mechanism inside reel housing 216, that allows earpiece cables 230, 232 to be manually extended from reel housing 16 as the user places earpieces 34, 36 in his or her ears.

Referring to Figs. 14 and 16, reel housing 116 includes a shaft 312 attached to and extending from the anterior wall 338 of the reel housing 216, and the shaft 312 extends toward the flexible posterior wall 240 of the reel housing 216. A slit 314 is formed in the upper portion of shaft 312. A cable reel 316 is located in reel housing 216, and a coil plate spring 318 is located in an open circular wall portion 320 of cable reel 316. When cable reel 316 is assembled in reel housing 216, an end 322 of spring 318 fits into slit 314 of shaft 312, holding one end of spring 318 against rotation. The other end of spring 318 is firmly attached to wall portion 320 of cable reel 316.

Reel 316 includes a plurality of angled ratchet teeth 324 mounted on a rim of the reel 316. A release actuator comprising a button 326, a stopper and release assembly including an arm 328, and the release button 326 is pivotally mounted to a shaft 330 attached to the anterior wall 238 of the reel housing 216. The underside of the outer end of stopper and release arm 328 includes a stop member (not shown) that is adapted to engage ratchet teeth 324 and allow rotation of cable reel 316 in the clockwise direction. When release button 326 is pivoted, and arm 328 is moved away from engagement with ratchet teeth 324, spring 318 will rotate reel 316 in a counter-clockwise direction, as will be explained. A small spring 332 engages a sidewall of reel housing 216, and biases stopper and release arm 328 into engagement with ratchet teeth 324.

In the embodiment illustrated in Fig. 15, a plurality of concentric conductive rings 334a, b, c, d are located on the anterior wall 238 of the reel housing 216. A printed circuit board 336 is positioned on the anterior wall 238 inside the reel housing 216, and includes a plurality of concentric conductive rings 334a-d. Each of the conductive rings 334a-d are electrically connected to cable 236 and connector plug 242 (Fig. 14) by solder points 338a-d (Fig. 15). In the illustrated embodiment, four spring wiper contacts (not shown) are attached to cable reel 116 and are aligned such that when cable reel 316 rotates, the spring wiper contacts remain in constant contact with a corresponding conductive ring 334a-d. The four wires in both earpiece cables 230, 232, are each connected to one of the spring wiper contacts on cable reel 316. Release button 126 rests against the flexible posterior wall 240 inside reel housing 216, allowing the user to press the outside of the flexible posterior wall 240 of reel housing 216 making release button 326 accessible to a user.

When a user desires to extract earpiece cables 230, 232 from reel housing 216, the user pulls outward on earpieces cables 230, 232 (Fig. 14) using a slight tension force. The stop member (not shown) on the underside of stopper and release arm 328 glides over ratchet teeth 324 as reel 316 rotates without engaging the ratchet teeth 324.

Simultaneously, spring 318 is wound, thus storing kinetic energy. When a sufficient length of earpiece cable 230, 232 has been extracted from reel housing 216, tension on the cables is released, and the stop member engages one of the ratchet teeth 324, preventing reverse rotation of cable reel 316. The stop member can be fixed at any point on the rotation of reel 316, allowing the user to extract any suitable length of earpiece cable 230, 232 and have the earpiece cable 230, 232 fixed at that extracted length until release button 326 is pushed inward.

When the user desires to retract earpiece cables 230, 232 into reel housing 216, finger pressure is applied to the outside of the posterior wall 240 of the reel housing 216 adjacent the release button 326 located inside the reel housing 216. The pressure applied to the release button 326 pivots the stopper and release arm 328 out of engagement with the ratchet teeth 324. The kinetic energy stored in spring 318 is released, rotating reel 316 in an opposite direction, thus rewinding earpiece cables 230, 232 onto reel 316. At all times during the extraction or retraction of earpiece cables 230, 232 relative to reel housing 216, the earpieces 234, 236 remain electrically connected to solder points 338a-d and to connector plug 242 (Fig. 14). Earpiece cables 230, 232 are prevented from being retracted fully inside of reel housing 216 since the outer diameters of earpieces 234, 236 at the point where they attach to earpiece cables 230, 232, respectively, are larger than the inner diameters of earpiece cable aperture 228.

The concentric ring-spring wiper contact, spring operated reel and lock-release designs illustrated in Fig. 15 and described above are well known in the field of electrical and mechanical design. However, the described retractable earpiece cable structure has not been used previously in a retractable and extendable earpiece cable assembly whose reel housing is integrally formed into a protective casing for a mobile communication or sound device.

The ends of earpiece cables 230, 232 opposite earpieces 234, 236 as described above, are electrically connected through solder points 338a-d to a connector plug cable 244 extending from a connector plug aperture 246 (Fig.14) in reel housing 216. The terminus end of connector plug cable 244 (Fig. 15) includes a connector plug 242 (Fig. 14) that is adapted to be inserted through the sound output portal aperture 248 (Figs. 16, 17, 18) of the casing 214 and into the sound output portal 250 of the mobile electronic device 212. For convenience, the connector plug cable 244 may be a self-coiling cable that is extended when connector plug 242 is inserted into sound output portal 250.

To operate the extendable and retractable earpiece cable assembly 18 illustrated in Figs. 14 and 15, a user must insert the mobile electronic device 212 into the casing 214 of the protective apparatus 210. The user then attaches carrying clip 220 to his or her belt, strap, backpack, item of clothing, etc., by pressing on the upper portion of carrying clip 252 (Fig. 14) and moving the bottom portion of carrying clip 254 away from the casing 214 and reel housing 216. When suitably attached to the apparel or accessory item worn by the user, upper portion of the carrying clip 252 is released, and carrying clip 220 holds the casing 214 and mobile electronic device 212 securely to the user's apparel or accessory item. If necessary or desired, the mobile electronic device 212 is activated to be able to receive and/or send electronic impulses that are transformed into sound at earpieces 234, 236.

The user then manually grasps earpieces 234, 236 and applies a tension or pulling force that extracts cables 230, 232 out of reel housing 216 through the earpiece cable apertures 228. As earpiece cables 230, 232 are extracted from reel housing 216, the spring 318 (Fig. 15) acting on the cable reel 316 inside reel housing 216 is wound, applying a tension force on the ends of earpiece cables 230, 232 extending around the cable reel 316. Upon extracting a sufficient length of earpiece cable 230, 232 from reel housing 216 to allow the user to insert one earpiece 234, 236 in each ear, the retraction process is halted, and the automatic reel brake mechanism shown in Fig. 15 is activated to brake the earpiece cables 230, 232 against being retracted back into reel housing 216 until the user has completed using mobile electronic device 212. Before the user can begin use of the mobile electronic device 212, the user must also manually grasp the connector plug cable 244 and gather enough slack to insert the connector plug 242 through the sound output portal aperture 248 and into the sound output portal 250.

The length of the connector plug cable 244 is determined by the relative position of the connector plug aperture 246 to the sound output portal aperture 248 and sound output portal 250, having enough connector plug cable 244 to reach the sound output portal 250 and plug the connector plug 242 into the sound output portal 250. However, the connector plug cable 244 should also be short enough to minimize potential snagging of the connector plug cable 244 on external objects during use. Once the connector plug 242 is inserted into the sound output portal 250, the mobile electronic device 212 can transmit an audio signal through the connector plug cable 244 and the earpiece cables 230, 232 into the earpiece 234, 236 and to the user.

To retract the earpiece cables 230, 232 back into reel housing 216, the user removes the earpieces 234, 236 from the ears, and applies a brief tug or tension force on the earpiece cables 230, 232. The spring operated cable reel 316 inside housing 216 is released as explained above, and the energy stored in the reel spring 318 when the earpiece cables 230, 232 were extracted from reel housing 216 rotates the cable reel 316 and draws earpiece cables 230, 232 back onto cable reel 316 and into reel housing 216 until each earpiece 234, 236 abuts reel housing 216 adjacent an earpiece cable aperture 228. It is not necessary to disengage connector plug 242 from sound output portal 250 when the mobile electronic device 212 is no longer being used.

Thus, as seen in Figs. 14 and 15, an extendable and retractable earpiece cable assembly 218 and an integral reel housing 216 is provided in a single unit integrally formed in the casing 214 encasing the mobile electronic device 212. The user need not carry separate headphones or earpieces and separate attachment devices or pouches when transporting and/or using their mobile sound or communication device. The invention described above and shown in Figs. 14 and 15 provides the user of the mobile electronic device 212 with the convenience of having the earpieces and attachment apparatus for their mobile device as a single unit, thus providing ease of use and aiding in preventing the loss of individual components.

Figs. 16 and 18 are side views of the protective apparatus 210 of Fig. 14 showing the extendable and retractable earpiece cable assembly 218 inside the reel housing 216 which is integrally formed with the casing 214 and carrying clip assembly 256. These figures depict input port apertures 258 to allow access through the casing 214 to input ports 260. Additionally, output port apertures 262 allow access through the casing 214 to output ports 264. The input port apertures 258 and output port apertures 262 can be placed in any position on the casing 214 to allow access to input ports 260 and output ports 264. Furthermore, the input port apertures 258 and output port apertures 262 can openly expose the input ports 260 and output ports 264 to the environment outside the casing 214 or the input port apertures 258 and output port apertures 262 can have a flexible removable membrane, for example, rubber or plastic, covering the input ports 260 and output ports 264 protecting the input ports 260 and output ports 264 from the environment.

Fig. 17 is a front view of the protective apparatus 210 showing the electronic display aperture 266 allowing access to the electronic display 268 and the sound output portal aperture 248 (Fig. 17) of the mobile electronic device 212, allowing access to the sound output portal 250. The electronic display aperture 266 can openly expose the electronic display 268 to the environment, or the electronic display aperture 266 can transparently cover the electronic display 268 protecting the electronic display from the environment, while still allowing the user to interface with the electronic display 268. Fig. 19 is another embodiment of the invention illustrated in Figs. 14-18 and 20, wherein the carrying clip 220 is mounted on the casing 214 from the left side of the casing 214 to the right side of the casing 214, instead of from the top of the casing 214 to the bottom of the casing 214. Fig. 19 illustrates that the position of the carrying clip can be altered to accommodate the position of input port apertures 258 and output port aperture 262, input ports 260 and output ports 264 which in this embodiment are located in the top middle portion of the casing 214. In another embodiment of the invention illustrated in Figs. 14-18 and 20 the carrying clip 220 can be mounted in any position to accommodate the needs of the manufacturer or user.

In a further embodiment of the invention, as shown in Figs. 21-24, the reel housing 216 is removably attached to the casing 214. As seen in Fig. 21, a reel housing attachment assembly 270 allows the reel housing 216 to be manually disengaged from the casing 214, and reengaged again with the casing 214. The reel housing attachment assembly 270 allows disengagement and reengagement of the reel housing 216 with the casing 214 to be repeated multiple times. The reel housing attachment assembly 270 comprises at least one reel housing attachment assembly female bracket 272 attached to the casing and at least one reel housing male attachment pin assembly 274 on opposed sides of reel housing 216 in the illustrated embodiment. This embodiment of the invention has the same amount of reel housing attachment assembly female brackets 272 as reel housing male attachment pin assemblies 274. In the illustrated embodiment, two brackets 272 and pin assemblies 274 are shown, however it is contemplated that the removable connection between reel housing 216 and casing 214 may comprise a single male-female attachment assembly, or more than two attachment assemblies. Each reel housing attachment assembly female bracket 272 is integrally formed with or attached to the casing 214 (Fig. 24) and each bracket is configured and spaced from an opposing bracket 272 (Fig. 22) so that reel housing 216 can be inserted between female brackets 272 thus removably securing reel housing 216 to the casing 214 (Fig. 22). Each bracket 272 includes at least one aperture 276 that is adapted to receive a spring-loaded male pin 278 extending from male attachment assembly 274 of reel housing 216. Each pin 278 is configured to fit snugly inside the corresponding aperture 276 (Figs. 22 and 24) of female brackets 272. Each aperture 276 allows the

corresponding spring-loaded male pin 278 to removably secure the reel housing 216 to the casing 214 after pins 278 are inserted through the corresponding female pin apertures 276 (Fig. 24).

Male attachment pin assemblies 274 are integrally formed as part of the reel housing 216 (Fig. 24). The pin assemblies 274 are spaced so that each pin assembly 274 is aligned with a corresponding aperture 276 of a bracket 272. Each spring-loaded male pin 278 rests in the extended position in a direction away from the center of the reel housing 216. The spring-loaded pins 278 are configured so that the tip of each pin 278 is rounded, allowing for easier insertion and removal from the apertures 276. The pin assemblies 274 are sized so that reel housing 216 removably attaches securely to the casing 214.

To securely attach the reel housing 216 to the casing 214, a user must push in toward the center of the reel housing 216 on each pin 278 of each assembly 274 so that the reel housing 216 can be inserted between the brackets 272. The reel housing 216 is not capable of fitting between the brackets 272 unless all of the spring-loaded pins 278 are pushed in towards the center of the reel housing 216. Once the spring-loaded pins 278 are pushed in toward the center of reel housing 216, the user places the reel housing 216 between the brackets 272 and against the casing 214 in a position whereby each spring-loaded pin 278 is aligned with a corresponding aperture 276. Once each spring- loaded pin 278 is in position aligned with a corresponding aperture 276, pin assemblies 274 will hold the pins 278 in the pushed-in or non-resting position toward the center of the reel housing 216. The user then slides the reel housing 16 into position between brackets 272 so that the spring-loaded pins 278 move back to their resting positions and extend through the corresponding apertures 276, securing the reel housing 216 against the casing 214 and between the brackets 272.

To remove the reel housing 216 from the casing 214, the user manually pushes inward on each spring-loaded male pin 278 protruding through and resting in the female apertures 276 so that the spring-loaded male pins 278 are no longer protruding in a perpendicular manner, relative to the brackets 272, through the apertures 276. The user simultaneously moves the reel housing 216 until each spring-loaded pin 278 is held in the non-resting position, pushed toward the center of the reel housing 216 by the brackets 72. Once the brackets 272 are pushing in on the tips of pins 278, the user can release manual pressure on pins 278 and remove the reel housing 216 from the casing 214.

In the embodiment of the invention shown in Figs. 21-24, the carrying clip assembly 256 is mounted on the reel housing 216, so that when the reel housing 216 is removed from the casing 214, the carrying clip assembly 256 remains attached to the reel housing 216. In another embodiment (not shown), the carrying clip assembly 256 is mounted directly to the casing 214. The reel housing mounting brackets 272 and each pin assembly 274 are configured on the casing 214 so that use of the carrying clip assembly 256 is not impeded regardless of whether the reel housing 216 is engaged with the casing 214. Furthermore, the carrying clip assembly 256 can be of a different design configured to avoid an impediment created by the brackets 272 when the reel housing 216 is disengaged from the casing 214, or with the reel housing 216 when the reel housing is engaged with the casing 214.
