Through manipulation of the turning knob, the taking-up and releasing unit brings the cord-winding unit to quickly take up or release the cord tied to the reel without being affected by the length of the cord wound around the reel.
Description
- The present invention relates to a cord taking-up and releasing device, and more particularly to a novel cord taking-up and releasing device that enables quick and safe taking-up and releasing of a cord tied thereto.
- Most of the currently available cord taking-up and releasing devices typically include a housing, a ratchet, a spiral elastic element, and a locking gear. A lot of invention and new utility model patents have disclosed cord taking-up and releasing devices having the above-mentioned basic structure in an attempt to improve the function and industrial value of the devices.
- Taiwanese Patent Publication No. 509017 discloses an automatic shoulder belt rewinder, which mainly includes a case, a cover plate, a ratchet, and a locking gear. The case defines an internal receiving space, and has a slot provided at an upper end of one side thereof. The cover plate is closed to an open side of the case. The ratchet is internally provided with a spiral elastic element and an axle, and mounted in the receiving space of the case. The locking gear is rotatably mounted to the slot at the upper end of the case. Both the ratchet and the locking gear are rotatably mounted in the receiving space of the case with a pawl plate of the locking gear engaged with teeth of the ratchet. When a shoulder belt wound around the ratchet is extended through the locking gear, it could be pulled outward from the case. When the shoulder belt is pulled outward, it brings the ratchet to rotate at the same time. At this point, teeth on the ratchet move clockwise without being caught by the pawl plate of the locking gear, and the belt could be pulled out to a desired length.
- Taiwanese Patent Publication No. 482183 discloses a mobile phone earpiece with automatically rewindable cord, which mainly includes a lower case, a reel, a cam, and an upper case. The lower case is provided with a recess for receiving the reel therein. The recess in the lower case has a central rotary shaft upward projected therefrom.
- The reel has an I-sectioned configuration to define an annular recess for the cord of the earpiece to wind therearound. A spring is mounted on the reel with an end fixed to the rotary shaft and the other end fixed to an outer edge of the annular recess. When the cord of the earpiece is pulled outward to a desired length, it may be held in place by the cam and a pawl. And, when the outward pulled cord held in place is pulled again, the reel is released from the pawl to freely rotate and thereby rewinds the extended cord of the earpiece.
- Taiwanese Patent Publication No. 473454 discloses a small-size electric cord reel. According to one of eight similar independent claims of the invention, there is provided an electric cord reel adapted to revolve on a spindle. The electric cord reel includes a spool, a length of releasable and rewindable electric cord having a plurality of conductors and a reinforced outer layer, a rotary mechanism attached to the spool, and an inner cable held in an inner chamber of the spool. The spool is rotatably mounted on the spindle, and has an annular wall defining an outer recess and the inner chamber. The rotary mechanism includes a spring, an end of which is connected to the spindle and the other end of which is connected to the spool. The disclosed small-size electric cord reel is characterized in that the spool has a diameter smaller than about 4 cm and a thickness less than about 2 cm, and that the releasable electric cord is about one meter or longer.
- Taiwanese Patent Publication No. 219450 discloses a freely rewindable tying device, which mainly includes a screw, an upper cover, a reel, a spiral spring, a seat, a tying cord, a collar, a U-shaped jacket, a hold-down cover, a retaining ring, a clip, and a brake block. The tying cord is counterclockwise wound in a recess of the reel, and the reel is mounted in the seat. The spiral spring has an inner end fixed to a post on the seat, and an outer end fixed to the recess of the reel.
- From the above-mentioned patents of prior art, it is found the spiral spring included in the rotary mechanism is used in the conventional taking-up and releasing devices to actuate the taking-up and releasing movements. The effectiveness of such structure is frequently subject to the length of the spiral spring. When the spring is too long, the rewinding ability thereof is reduced accordingly. That is, the conventional taking-up and releasing devices are not able to effectively release and rewind an overlong cord or similar linear material.
- It is therefore desirable to develop an improved taking-up and releasing device with different spatial and functional design to overcome the problems existed in the above-mentioned conventional devices.
- A primary object of the present invention is to provide a cord taking-up and releasing device that is not functionally restricted by a length of the cord to be taken-up or released.
- To achieve the above and other objects, the cord taking-up and releasing device of the present invention includes a main body consisting of a housing, a turning knob on a top of the housing, and a seat below the housing; a taking-up and releasing unit received in the housing and including an upper shaft collar, an upper ratchet, a lower ratchet, a first shaft, inner and outer elastic elements, a retaining gear, and a C-shaped retaining ring; and a cord-winding unit mounted on the seat of the main body and including a reel, a lower shaft collar, and a second shaft.
- The housing of the main body is provided at a top surface with a first guide hole, and near a lower end with two opposite through holes. The seat of the main body is provided with a second guide hole, and a bottom of the main body is connected to an article having a cord to be tightened or loosened via the cord taking-up and releasing device.
- The first shaft of the taking-up and releasing unit has a lower end fixedly engaged with the retaining gear.
- The reel of the cord-winding unit has a shaft hole rotatably mounted around the second shaft, which is fixedly mounted in the second guide hole of the seat.
- A cord or a linear material is connected to the reel by extending two ends of the cord into the main body via the two spaced through holes on the housing.
- The upper ratchet is immovably mounted in an upper part of the housing, and has a diameter larger than the lower ratchet. The lower ratchet has a lower portion formed into a diametrically reduced cylindrical column, around which the outer elastic element is mounted to normally push the lower ratchet upward to engage with the upper ratchet, such that the lower ratchet could be rotated clockwise but not counterclockwise. In a shaft hole of the lower ratchet, there are provided with guide slots to engage with an upper end of the retaining gear, so that the retaining gear is limited to slide upward and downward only along with the lower ratchet.
- The first shaft is upward extended through shaft holes of the lower ratchet, the upper ratchet, and the upper shaft collar to project from the housing via the first guide hole and connect to the turning knob. When the turning knob is turned clockwise, the first shaft, the retaining gear, and the reel are brought to turn along with the lower ratchet, so that the cord tied to the reel is wound around the reel and tightened. Reversely, when the turning knob is turned counterclockwise, the immovable upper ratchet prevents the lower ratchet and other parts coupled therewith from rotating reversely. To loosen or release the cord, simply upward pull the turning knob for the first shaft and the retaining gear to synchronously slide upward and disengage a lower end of the retaining gear from axial guide slots at an upper end of the reel, so that the reel is allowed to freely rotate reversely to release the cord, and the cord in a loosened state could be pulled outward via the two spaced holes on the housing.
- With the above arrangements, the cord taking-up and releasing device of the present invention is more easily operable and not functionally affected by the length of the cord to be wound around or released from the reel.
- The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein

As can be clearly seen from the drawings, the cord taking-up and releasing device of the present invention mainly includes a
main body 10 consisting of aturning knob 11, ahousing 12, and a seat 13 (seeFIG. 3 ); a taking-up and releasingunit 20 received in thehousing 12 of themain body 10 and including anupper shaft collar 21, anupper ratchet 22, alower ratchet 23, afirst shaft 24, inner and outerelastic elements retaining gear 27, and a C-shaped retaining ring 28; and a cord-windingunit 30 mounted on theseat 13 of themain body 10 and including areel 31, alower shaft collar 32, and asecond shaft 33. - The
housing 12 of themain body 10 is provided at a top with afirst guide hole 121, near a lower end with two diametrically opposite or circumferentially properly spacedholes 122, on an inner wall surface with anannular groove 123, and along a lower annular end surface with a plurality of spaced fixing holes 124 (seeFIG. 4 ). - The
seat 13 of themain body 10 is provided at a center with asecond guide hole 131, and at areas surrounding thesecond guide hole 131 with a plurality of radiallyinner holes 132 corresponding to thefixing holes 124 at the lower end surface of thehousing 12, and a plurality of radiallyouter holes 133. Theseat 13 is fixedly connected at an upper side to the lower end surface of thehousing 12 by upwardscrewing fastening elements 134 through theinner holes 132 into thefixing holes 124, and at a lower side to an article having a cord to be tightened by screwingfastening elements 134 through theouter holes 133. - The
upper shaft collar 21 of the taking-up and releasingunit 20 has an upper end fixedly received in thefirst guide hole 121 of thehousing 12, and a radially extendedlower flange 211 bearing against an inner side of the top of thehousing 12. Theupper shaft collar 21 also defines acentral shaft hole 212 axially extending through theupper shaft collar 21. - The upper and the
lower ratchet unit 20 mutually engage with each other, and are provided with central shaft holes 221, 231, respectively. Theupper ratchet 22 is diametrically larger than thelower ratchet 23, and is immovably fitted in an upper part of thehousing 12. Thelower ratchet 23 is provided in thecentral shaft hole 231 near a lower end thereof withguide slots 232, and has a lower portion formed into a diametrically reducedcylindrical column 233 to provide a radially extended surface between an upper portion and the reducedlower portion 233 of thelower ratchet 23. The outerelastic element 26 is mounted around the reducedlower portion 233 of thelower ratchet 23 with an upper end of the outerelastic element 26 normally pressed against the radially extended surface. - The
first shaft 24 of the taking-up and releasingunit 20 is provided on an outer surface with aflat portion 241 axially extended from top to bottom of thefirst shaft 24. Thefirst shaft 24 has a lower end fixedly fitted in an upper end of ashaft hole 271 of theretaining gear 27 for theretaining gear 27 to always move along with thefirst shaft 24, and an upper end having the innerelastic element 25 mounted therearound. That is, the innerelastic element 25 is mounted around the upper end of thefirst shaft 24 to locate between thelower flange 211 of theupper shaft collar 21, an upper end of which is fixedly received in thefirst guide hole 121 of thehousing 12 and provides a stationary end, and the upper end of theretaining gear 27, which provides a movable end. More specifically, a lower end of the innerelastic element 25 is pressed against a top surface of theretaining gear 27, so that thefirst shaft 24 and theretaining gear 27 are always brought by an external force to synchronously slide upward or return to a home position. Moreover, the upper end of thefirst shaft 24 is sequentially upward extended through the shaft holes 231 of thelower ratchet 23, theshaft hole 221 of theupper ratchet 22, and theshaft hole 212 of theupper shaft collar 21, and finally fixedly connected to the turningknob 11. The C-shapedretaining ring 28 is press-fitted in theannular groove 123 in thehousing 12 to provide a fixed place for a lower end of the outerelastic element 26, and thereby enables the outerelastic element 26 to normally press its upper end against the radially extended surface above the diametrically reducedlower portion 233 of thelower ratchet 23. - The
reel 31 of the cord-windingunit 30 is provided at an upper end with a plurality of axially extendedguide slots 311 for a toothed lower end of theretaining gear 27 to slide thereinto, at a lower central area with a hollowcylindrical chamber 312, and at a middle portion between upper and lower ends thereof with a radially inward curvedperipheral surface 313 for winding acord 14 therearound. The radially inward curvedperipheral surface 313 is provided at two properly spaced points with two retainingholes 315, to which two ends of thecord 14 are tied and fixed in place. Acentral shaft hole 314 axially extended between the upper end with theguide slots 311 and the lowercylindrical chamber 312 is provided in thereel 31. - The
lower shaft collar 32 of the cord-windingunit 30 is provided at a central area with an axially extendedshaft hole 321, and at a lower portion with a diametricallyreduced neck 322 for fixedly mounting in thesecond guide hole 131 of theseat 13 of themain body 10. Thesecond shaft 33 has an upper end rotatably received in theshaft hole 314 of thereel 31, and a lower end fixedly fitted in theshaft hole 321 of thelower shaft collar 32 to locate in the lowercylindrical chamber 312 of thereel 31 along with thelower shaft collar 32. - Please refer to
FIG. 4 . When the turningknob 11 is turned clockwise, thefirst shaft 24 and theretaining gear 27 are brought to rotate synchronously. Since thefirst shaft 24 is pressed by the innerelastic element 25 against the top of theretaining gear 27 to normally slide downward, the toothed lower end of theretaining gear 27 is normally received in theguide slots 311 at the upper end of thereel 31. On the other hand, the upper end of theretaining gear 27 is normally engaged with theaxial guide slots 232 in thelower ratchet 23, allowing the retaininggear 27 to slide upward and downward only. Moreover, since the outerelastic element 26 wound around the reducedlower portion 233 of thelower ratchet 23 normally pushes the latter upward to engage with theupper ratchet 22 fixedly received in thehousing 12, the clockwise turning of the turningknob 11 would bring thefirst shaft 24, the retaininggear 27, and thereel 31 to move along with thelower ratchet 23 to wind thecord 14 around the radially inward curvedperipheral surface 313 of thereel 31 and thereby tightens thecord 14. And, when the turningknob 11 is turned reversely, since thelower ratchet 23 is completely checked by the fixedupper ratchet 22 from rotating, the taking-up and releasing unit and the cord-winding unit are not rotated. When it is desired to loosen thecord 14, simply pull and hold the turningknob 14 upward, so that thefirst shaft 24 brings the retaininggear 27 to slide upward and disengage the toothed lower end from theguide slots 311 at the upper end of thereel 31. At this point, thereel 31 is no longer retained by the retaininggear 27 and allowed to rotate reversely, and a user may release thewound cord 14 from themain body 10 by pulling thecord 14 outward via the two spacedholes 122 on thehousing 12. - The present invention may have many different applications.
FIGS. 5 and 6 show two examples of the application of the present invention. As shown, the cord taking-up and releasing device of the present invention may be used on asports shoe 40 or abag 50 to tighten or loosen alace 14 thereof. - Unlike the conventional taking-up and releasing devices, the present invention provides upgraded winding ability to enable convenient adjustment of the length of a cord or any other type of linear material. With the present invention, it is no longer necessary to take time to tie and untie the cord tightened with the present invention.
- The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
