The present invention relates generally to personal computers, and cabling used therewith.
The desktop space near a personal computer is often times cluttered which creates an unsightly mess as well as reduces a user's efficiency. Prior solutions have been to move peripheral device connectors from the back side of the personal computer to the front side. This was a major selling point for some personal computers when it was introduced and now has become a desirable feature. The disadvantage is that although it addresses the convenience factor of not having to get behind the personal computer to connect temporary cables to peripheral devices, it does not address the issue of clutter or providing a home for the cable when it is not attached the peripheral device.
It would be advantageous to reduce or eliminates the clutter associated with unused cables that attach to peripherals that are not permanently attached to the personal computer. It would also be advantageous to locate a cable after it has been stored by providing a consistent home for the cable.

However, none of the above-cited patents appear to disclose or suggest a personal computer having a retractable cable system adjacent its front surface or panel that is used to connect the personal computer to peripherals
The present invention provides for a personal computer system having a retractable cable system or mechanism for use in connecting a first computing device to a second computing device. The retractable cable mechanism is disposed adjacent to and internal to a front panel of the first or second computing devices. This allows a user to interconnect the first or second computing devices by means of a cable that is preferably retracted inside of the personal computer when not in use.
The various features and advantages of embodiments of the present invention may be more readily understood with reference to the following detailed description taken in conjunction with the accompanying drawing figure, wherein like reference numerals designate like structural elements, and wherein:
Referring to the drawing figures,
As is shown in
In accordance with one aspect of the present invention, the retractable cable system 20 is disposed adjacent to and internal to the front panel 12 of the housing 11. The exemplary retractable cable system 20 shown in
The exemplary retractable cable system 20 comprises a housing 21 that captures two cable connectors 24, 25. Each cable connector 24, 25 is connected to its own cable 26 that extends through openings at the rear of the housing 21. Each cable 26 is coupled to a separate retractable cable mechanism 27 disposed within the housing 11 of the personal computer 10a. Each retractable cable mechanism 27 is a spring-loaded retraction device, winding mechanism, or reel, that reels in the cable 26 upon activation by a user. Such retractable cable mechanisms 27 are generally well-known in the art as is evidenced by the prior art patents cited in the Background section.
The retractable cable mechanisms 27 are configured so that the cables 26 and attached connectors 24, 25 may be pulled away from the front surface 12 of the personal computer 10a to a desired length that allows each cable 26 to reach and be connected to a selected peripheral device 30. This is illustrated in
The retractable cable devices disclosed in U.S. Pat. Nos. 5,544,836, 5,671,833, or 5,923,147, for example, cited in the Background section, may be adapted for use in the present invention. The contents of these U.S. Patents are incorporated herein by reference in their entirety. Thus, the retractable cable mechanism 13 may be similar to that disclosed in these patents, or similar in design to other patents cited in the Background section.
The cables 26 and connectors 24, 25 may comprise universal serial bus (U.S.B) or IEEE-1394 cable devices, for example. It is to be understood that other existing or to-be-developed cable and connector types may also be employed in the present invention. The cables 26 are preferably retracted into the housing when not in use. The length of each cable 26 may also be configured to extend from the personal computer 10a a specific length that allows connection to the external device 30. This helps to minimize desktop clutter.
Peripheral devices 30 employing U.S.B and IEEE-1394 connectors 24, 25 often times use more than one type of connector 24, 25 in connecting to the peripheral devices 30. Manufacturers have created adaptors 23 that translate from a standard size connector 24, 25 to a variety of mini or non-standard connector sizes. These adaptors are generally small in nature.
As is shown in
The present retractable cable system 20 may also be used with other cables 26 such as power cords, keyboard cables, and mouse cables, and the like, as long as they are connected at the front side of the personal computer 10a or peripheral device 30.
The present invention eliminates clutter associated with unused cables 26 that are used to attach to peripheral devices 30 that are not permanently attached to the personal computer 10a. The present invention also provides for a storage location for the cables 26 after they have been used by providing a home for the cables 26.
Benefits of the present invention are that it allows the cables 26 to be just the right length when attached between a personal computer 10a and a peripheral device 30. The retractable cable mechanism 20 retracts the cables 26 when not in use, thus reducing desktop clutter. The housing 11 of the retractable cable mechanism 20 provides a storage location for the small adaptors 23 that convert between standard U.S.B or IEEE-1394 connectors and a variety of mini connectors.
The present invention thus provides a storage location for a cables 26 when they are retracted, and thus a user does not have to search for the cables 26 when they are needed. The present invention allows personal computer manufacturers to tout convenience and usability over its competitors, analogous to when cup holders or front side U.S.B and 1394 ports first became available.
Thus, a personal computer system having a front-side retractable cable system for use in connecting the personal computer to a peripheral device has been disclosed. It is to be understood that the above-described embodiment is merely illustrative of some of the many specific embodiments that represent applications of the principles of the present invention. Clearly, numerous and other arrangements can be readily devised by those skilled in the art without departing from the scope of the invention.
