Description

MULTI-ATTACHMENTED PORTABLE RADIO
This invention relates generally to portable radios and more particularly to portable radios of the type which receive messages, such as those commonly known as pagers.
As technology has advanced, so the size of portable radios has decreased to the point where they are commonly of such a size that can easily fit into a pocket or a purse. It is known in the prior art for such pocket-sized portable radios to be provided with a clip so that they may be clipped to, for example, a pocket or a belt. It is also well known that other types of portable articles such as compact cameras or portable tape players are provided with different types of carrying means such as wrist straps, but in none of these cases does the person carrying the article have the opportunity to choose for themselves the mode of carrying or wearing the article.
It is thus an object of the present invention to provide means whereby the end user of a portable radio can choose how to carry or wear the radio.
Therefore, according to one aspect of the invention, there is provided a portable radio system comprising a portable radio having a housing including coupling means and a plurality of different, interchangeable attachment devices having coupling means which are complementary to the housing coupling means for coupling any one of the attachment devices to the radio housing, wherein the attachment devices are configured for attachment to an end user.
The portable radio is preferably a pager and the attachment devices may be configured for attachment to different parts of an end user which may be an accessory device, such as an auxiliary display unit, a recording machine, a battery recharging unit, a modem, a facsimile machine, a computer interface .unit or a printer unit, or maybe a person. In the case of the end user being a person, the attachment devices are preferably configured for attachment to the person's clothing or body and may differ by being of different colors or for attachment to. different parts of the person's clothing or body. For example, the attachment devices may include tie or belt clips, pendants, wrist straps, brooch clips, fobs or even belt buckles.
The housing and attachment device coupling means preferably comprise a recess having indents therein and a complementary protuberance having detents thereon which fit into said indents in the recess when coupled together. In a preferred embodiment, the detents are spring-loaded and the coupling means include means for retracting the detents into the protuberance when it is to be inserted into the recess.
The housing and attachment device coupling means preferably also include complementary electrical coupling means for electrically coupling the portable radio to the accessory device. There may also be provided a filler element for blanking off the radio housing coupling means when not coupled to an attachment device. Preferably, the system also includes at least one accessory module, such as a calculator module, a timing module or an auxiliary display module, having complementary coupling means thereon for coupling between the radio housing and the attachment device.
According to other aspects of the invention, there are provided methods of mounting a portable radio on an end user and of carrying a portable radio, comprising the steps of selecting one of a plurality of different, interchangeable attachment devices, coupling the selected attachment device to the portable radio via coupling means thereon; and attaching the portable radio, via the attachment device coupled thereto, onto the end user or onto an appropriate part of a person's clothing or body.
The invention will now be more fully described, by way of example only, with reference to the drawings of which:-
FIG. 1 shows three views of a pager for use in the system according to the invention;
FIG. 2 shows in greater detail part of the pager of FIG. 1;
FIGS. 3-9 show different types of attachment devices for use with the present invention;
FIG. 10 shows in greater detail part of the attachment devices of FIGS. 3-9;
FIGS. 11-14 show different types of accessory devices for use with the invention;
FIG. 15 shows an accessory module for use with the invention; and
FIG. 16 shows a blanking element for use with the invention.
Thus, there is shown in FIG. 1 a portable radio (1) of the type known as a pager which receives RF messages from a transmitter, decodes them and displays them on a display (2) to be read by the user of the pager. Conventionally, such pagers have loudspeakers (3) which provide an audible indication to the user that a message has been received, and may also have various controls (4) to cancel the display or otherwise control its size, brightness, etc. or the volume of the audible indication. The pager is formed from a housing in two halves: a front half (5) having the display (2) and controls (4) thereon, and a rear half (6) as shown in the figure. The rear half 6 has an opening to a battery housing which is closed by a battery housing cover (7) .
The rear half (6) of the housing also includes, in accordance with the invention, a coupling means (8) comprising a recess (9) in the pager (1) for coupling the pager to an attachment device. This coupling means (8) is more clearly shown in FIG. 2. The recess (9) is a parallelepiped having a plurality of electrical contacts (10) upstanding from the base thereof, and an indent (11) in the two ends of the recess (9) . The recess (9) may, of course, be of other configurations but must be so shaped as to be able to receive a complementary coupling means situated on an accessory. Such a complementary coupling means comprises, as shown in FIG. 10, an element (12) which is mounted on an accessory (13) to be coupled to the pager (1) . The element (12) comprises a parallelepiped of such a size and shape as to fit into the recess (9) in the pager (1) , and has two spring-loaded detents (14, 15) on the ends thereof which lock into the indents (11) of the recess (9) in order to retain the element in the recess . The detents (14, 15) are spring-loaded so as to be biased outwards in order to retain the element in the recess but may, if the configuration of the accessory allows, be retractable by a pair of thumb-operated retractors (16, 17) which are slidably movable against the force of the springs to retract the detents (14, 15) into the element for ease of insertion into the recess (9) .
As described above, the size of modern day pagers is such that they are frequently worn in a shirt pocket or on a belt, but it has never previously been possible for the user to choose from a wide range of possible wearing modes . FIGS. 3-9 show a selection of possible attachment devices, all having mounted thereon a coupling means of the type described above and as shown in FIG. 10. It will be appreciated that other configurations are possible and that these particular devices are shown by way of example only.
Thus, FIG. 3 shows a belt clip (18) having the element
(12) mounted thereon. The belt clip comprises an attachment arm (19) for clipping to the belt, pivotably coupled to the element (12) so as to allow the pager to have some freedom of movement when attached to the belt .
In FIG. 4, the element (12) is mounted on a base plate (20) which carries a safety pin (21) for pinning the pager to clothing in the form of a brooch. FIG. 5 shows the element (12) mounted on a T-shaped base plate (22) . The transverse arm of the base plate (22) carries a spring biased clip (23) parallel to the element (12) for clipping the pager to a tie worn by a user. In FIG. 6, the element (12) is mounted on a base (24) carrying an eyelet (25) through which is threaded a chain (26) to enable the pager to be carried around the neck in the form of a pendant.
FIG. 7 shows an accessory device in the form of a wrist strap comprising a mounting plate (27) having a strap (28) attached to two sides thereof for wearing around a user's wrist. The plate (27) carries the element (12) on its central portion and has a protective edge (21) around the perimeter thereof of such a size as to allow the pager to fit within it. It will, of course, be apparent that such a configuration will not allow the retractors (16, 17) to be provided as the pager would have to be fitted directly onto the element. This figure also shows a recess (30) provided in the element (12) necessary to allow the element to fit around the electrical contacts (10) provided in the recess (9) for connection with other types of accessories to be described below.
In FIG. 8, there is shown a fob comprising a clip (31) connected via a short length of chain (32) to the element (12) . Such a fob may be used by attaching the clip to a belt or pocket edge for security purposes but allows the pager to be carried in the pocket, for example.
FIG. 9 shows a belt buckle allowing the pager to be carried at the front of the belt in place of a normal buckle. The buckle comprises a main housing (33) having a recess (34) in the center thereof for receiving the pager. The bottom of the recess (34) carries the element (12) similarly to the wrist strap of FIG. 7. The outside front portions of the housing (33) may, of course, be decorated in any desired fashion. The underside of the housing (33) carries at one end thereof an arched element (35) forming a slot between it and the housing through which slot the belt is threaded. The other end of the housing carries an L- shaped spigot (36) which is inserted through a hole in the belt in order to fasten the belt securely.
If the user of the pager is sitting at a desk, there is no need for the user to actually be wearing the pager.
It could be simply placed on the user's desk or it could be connected on an accessory device. Such an accessory device may be a device for connecting the pager to a computer either directly by means of an interface unit or via telephone lines by means of a modem. Such a device is shown schematically in FIG. 11 wherein the device includes a recess (37) having the element (12) therein for coupling to the pager. In this case, the element (12) carries electrical contacts (38) for coupling with the electrical contacts (20) mounted on the base of the recess (9) of the pager. By means of these contracts, the pager can be electrically connected to the modem or computer interface unit for communication therewith. Such communication is controlled by the user using the controls (39) mounted on the device. The pager may alternatively be coupled to a printer unit or a facsimile machine in order to print out or fax any messages stored therein. Such an accessory device is shown in FIG. 12 and comprises a recess (40) having the element (12) with electrical contacts (38) thereon, a printing mechanism (41) including paper (42) , and controls (43) for controlling the device. Messages stored in the pager may alternatively be recorded onto tape using a recording machine as shown in FIG. 14. Such a machine includes a recess (44) having the element (12) with electrical contacts (38) and a conventional recording mechanism (45) which receives a tape cassette and includes controls (46) . An alternate desk-top accessory device is shown in FIG. 12. This is an auxiliary display device and includes a recess (47) having the element (12) with electrical contacts (38) for connection to the pager, and a display screen (48) with controls (49) associated therewith to enable messages to be displayed on a larger screen which is more easily viewed at a desk. A further accessory device which may be provided is a battery recharging unit for recharging the pager batteries whilst the user is sitting at a desk, and this unit may be incorporated into any of the above described desk-top accessories, although . it may, of course, also be provided as a separate unit.
If the user desires to simply keep the pager in a pocket, there is also provided a blanking element (54), shown in FIG. 16, which includes retractors (55, 56) for detents (57, 58) which are similar to those on the coupling devices described with reference to FIG. 10. However, in this case, the element (54) is not mounted on anything and is used merely to blank off the recess of the pager and to protect the electrical contacts (10) therein.
In a further development of the present invention, there may also be provided a set of accessory modules for adding to the pager and mounting between the pager and the attachment device or desk-top accessory device. Such accessory modules may include calculator modules, watch or timing modules or auxiliary display modules, or a combination of any of these . FIG. 15 shows such a combined calculator, watch, and display module. It comprises a housing (50) having a recess (51) in a front face thereof and extending through one end of the housing. The recess has the element (12) with electrical contacts (38) for coupling to the pager in the manner described above. The front face of the module also includes a display means (52) and control keys (53) thereon. The control keys are used to enter calculations when using the calculator function of the module, or to adjust the timing function of the module which is displayed on the display means (52) . The module can also be used simply as an auxiliary display device to expand the display capacity of the pager. Since this module is designed to be portable along with the pager, it is provided on its back face with a coupling means such as that described above with reference to FIG. 2 in order to allow it to be coupled to any of the attachment or accessory devices described above.
Thus, there has been described a system which dramatically expands the possible modes of wearing and operating a pager. Such a system allows the user to have the option of various styles of pagers without the need for new receivers, decoders, antenna or mechanics to be produced for each version by the manufacturer. The system allows the pager to be adapted to the clothing and fashion of the user. It will be appreciated, of course, that the attachment devices may be produced in a variety of colors to match the colors of the clothing worn by the user. It will further be appreciated that although specific attachment devices, accessory devices, and accessory modules have been described and illustrated, the invention is not limited to these particular embodiments but is intended to incorporate other embodiments which are within the scope of the claims.
