## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of provisional patent application Ser. No. 60/839,169, filed Aug. 22, 2006, which is incorporated herein by reference.


BACKGROUND OF THE INVENTION
The broad aspects of the invention relates generally to key holders for holding at least one key of any type or design. The key holder also may include other useful accessories and features.
U.S. Pat. No. 7,032,419, which is incorporated herein by reference, discloses a key holder with an inner and an outer housing. Keys are held on a ring keeper. The ring keeper is connected to a pin which transfixes the inner and outer housings. The pin has buttons on either end, for easier manipulation. When the pin is drawn up further into the inner and outer housings, the ring keeper is drawn up into the inner housing. At the top of the pin's travel, it is manipulated into a notch, which holds the keys in a retracted position. The inner housing has a hole its side. A plug of soft material is mounted inside the outer housing. When the pin is manipulated into the notch, this causes the inner housing to tilt inside the outer housing, and the keys are brought into contact with the plug of soft material. The plug of soft material dampens movement and rattling of the keys.
Although the patented key holder works well with conventional keys, many vehicles currently use “remote keys” which cannot be held in the key holder. This problem is solved by the improvements in the present aspect of the invention. Also, the present invention provides such a key holder with convenient, space saving accessories

DESCRIPTION OF THE INVENTION
One embodiment of the key holder KH described herein is illustrated in FIGS. 1 through 14, provides for hinges (44 and 46) on the outer housing, and allowing the front outer housing (10) to swivel open. A clasp (48) keeps the front and back of the outer housings (10 and 34, respectively) from swiveling open, until it is opened by the user. The outer housing (which comprises front and back outer housings 10 and 34 respectively) have also been widened near their bases and define an inner chamber 51 that is sized and positioned to contain a remote key (RK) when the remote key is stored in the key holder.
There is an inner housing comprised of front and rear inner housing (26 and 38), respectively, that can be withdrawn into, or extended partway out of the outer housing. The keys can be held against plug 28 to keep from rattling, all as described in U.S. Pat. No. 7,032,419, which is incorporated herein by reference. It will be noted that a remote key (RK) can be positioned in chamber (51) when the inner housing (and keys therein) is retracted into the key holder, so that all keys are secured in the holder.
There is a loop (50) on the rear outer housing (34) to attach remote key (RK) to the key holder by a small chain (C). An optional small clock (49) or watch may also be placed on the front outer housing (10). There is an opening (53) at the end of a small horizontal portion of the notch (54). Notch (54) allows travel of the button pin (32) to retract or extend the keys. Opening (53) is on the front outer housing (1) is large enough to allow the front button (20) to pass through the notch when front outer housing (10) is opened. A small groove or indentation (60) is made in one or both of the outer housings near the loop (50) to allow a chain (C) to run from the loop to a remote key, while the remote key is contained in the key holder.
Another aspect of the invention, best illustrated in FIG. 15 in an open position with a remote key contained within, comprises a securing button (52) in place of clasp (48). Also employed is a spring (57) on rear outer housing and hook (55) on the front outer housing, to assist in the opening of the front and rear outer housings (10 and 34, respectively).
Another aspect of the invention is illustrated in FIGS. 16 and 17 comprises front outer housing (10) and rear outer housing (34) that do not swivel open as above described designs. As can be seen, the bottom left of the key holder (viewed from the front) has been expanded to accommodate a remote key when the key holder is in retracted position, and the inner housing is tilted to the side, which is similar to the embodiments of the key holder described above.
The key holder includes loop (50). A Sliding plate (56) covers the top part of the key holder, and slides on grooves to make an opening at the top of the key holder that will allow the entry or exit of a remote key into or out of the retractable key holder. To keep sliding plate (56) in place when the top of the key holder is closed, friction according to the design of the grooves could be used, or a spring could be mounted inside the outer housings (10 and 34) to keep the sliding plate in a closed position, or bumps, or “snaps” in the grooves that attach sliding plate (56) to the outer housings could be made in such a way that a small amount of force is necessary to move sliding plate (56) to a position that opens the top of the key holder. Any structure that holds sliding plate (56) in a closed position is contemplated by the invention.
When sliding plate (56) is in the open position, there is an opening (59) in the top of the key holder that allows the entry or exit of a remote key (RK). In one embodiment sliding plate (56) does not completely close the top of the key holder to allow a small chain attached between loop (50) and the remote key (RK) to extend into the holder. A groove or indentation (60) in sliding plate (56) or in one of the outer housings could be employed to allow the small chain to run from the remote key RK when contained in the key holder to loop (50) on top of the key holder. Loop (50) could either be on top of sliding plate (56) or located elsewhere on the outer housings of the key holder.
FIG. 16 is front view with the top of the key holder in a closed position, FIG. 17 as a partial cut away view, again with the key holder in a closed position. FIG. 18 shows the key holder in a retracted position, with the top of the key holder open, and a remote key (RK) contained inside the key holder. Sliding plate (56) can slide to a closed position, containing the remote key inside the key holder.
FIGS. 19 and 20 illustrate another aspect of a key holder KH constructed similarly to those embodiments described above. Key holder KH includes a watch and a small flashlight. A button 61 actuates a light bulb 62. A battery 63 is operatively connected between the actuation button 61 and bulb to provide power to the bulb.
FIGS. 21 and 22 illustrate a key holder KH incorporating a cell phone. The cell phone comprises a screen 64, which is substantially flat and incorporated into the case. A key pad 65 is used for entering numbers or text messaging. The buttons are generally flat or actually recessed into the case. An antenna 66 provides improved signal reception. The cell phone has conventional internal components indicated generally by 67 as well as a power source, in this embodiment replaceable battery 69. The internal components and battery are as flat and compact as necessary to fit inside the key holder case.
The key holders KH as illustrated incorporates some of the same key retraction and sound dampening features included in the embodiments of FIGS. 13 and 14 as described in U.S. Pat. No. 7,032,419, which is incorporated herein by reference. Briefly described, a key holder capable of retracting keys within itself. The Key holder KH includes an outer case 10 that has a retraction groove 11 in the front wall. There is a pivotable inner housing 26 that also has a retraction groove 13. A button 20 is accessible outside the case and attached to a transverse pin 22. The pin is connected to a keeper 24 to which a key K is attached. There is a sound dampening plug 28 of soft material such as cotton attached to the inner wall of the case. The user can slide the button 20 up the grooves 11 and 13 retracting the key K into the inner housing 26. The button is slid over in the groove 13 so that the inner housing 26 abuts the plug 28 to provide for sound dampening.
The foregoing written description and accompanying drawings are intended to be illustrative of the broader aspects of the invention. Therefore, they should not be construed so as to limit the scope of the appended claims.
