Abstract
Conventional keys can be stored in a flat panel for carrying in a person's pants pocket or purse. Each key is stored in a flat slot extending from one edge of the panel. A push-button on the panel can be moved along the panel surface to push the key out of the panel or to pull the key into the panel. The push-button is attached to the key by a flexible connector that has a lost motion connection to the push-button. The lost motion connection allows the key to be spaced from the panel so as to be manipulatable without interference from the panel.
Description




BACKGROUND OF THE INVENTION




This invention relates to a key storage device, and particularly to a key storage device having a relatively flat compact shape, whereby the device can be readily placed in a person's pocket for ready access when needed.




It is a common practice to hang keys (e.g. car keys, house keys, and safe deposit keys) on a key chain or key ring. The loose keys can rub against the interior surface of the person's pants pocket so as to possibly wear a hole in the pocket fabric. Also, the sharp edges or ends of the loose keys can penetrate the pocket fabric to generate uncomfortable pressure on the person's skin.




The present invention relates to a flat key storage device that can be placed in a person's pocket or purse without damaging the fabric or exerting an uncomfortable pressure on the person's skin. In one preferred embodiment of the invention, the key storage device comprises a flat panel structure having plural slots therein for receiving individual keys. Each key is connected to a flexible chain or wire that has a lost-motion attachment to a slidable push-button mounted on the panel.




Each push-button can be moved in one direction on the panel to eject the associated key from the panel; the flexible chain or wire allows the key to be moved a limited distance from the panel while still preventing the key from becoming permanently separated from the panel. The key can be inserted into a lock while attached to the chain or wire.




Each push-button can be moved in the opposite direction on the panel to draw the associated key back into the panel. The flexible chain or wire can be moved relative to the push-button to permit complete insertion of the key into its slot.




The invention is advantageous in that the individual keys can be stored within the panel so as to be entirely enclosed. Nevertheless, individual keys can be withdrawn a considerable distance out of the panel when it becomes necessary to use them for unlocking purposes. The keys are permanently connected to the panel, via the chain or wire, such that the keys cannot be lost or mislaid.




Further features of the invention will be apparent from the attached drawings and description of an illustrative embodiment of the invention.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION





FIG. 1

shows a preferred form of the invention. As shown in

FIG. 1

, the invention comprises a key storage device that includes two similarly constructed panels


10


,


10


connected together by hinges


12


,


12


, whereby the panels can be closed against one another or separated from one another (while still being connected by hinges


12


,


12


).

FIG. 1

shows the two panels hinged apart. The two panels will normally be closed together in a compact two-layer condition for storage in a person's pocket or purse. A patch of fibrous adhesive material


14


on the lowermost panel mates with a companion adhesive patch on the uppermost panel to releasably hold the two panels together. Materials available under the tradename VELCRO can be used for the adhesive patches. Other types of clasps or latches can be used.




Each panel


10


is adapted to store three keys, numbered


16


. The size of each panel can be increased, or decreased, to store different numbers of keys. Each key


16


is stored in an individual slot


18


in the panel.

FIG. 1

shows one key


16


fully withdrawn from the uppermost panel


10


, and two keys


16


fully inserted into the uppermost panel. Each key


16


is attached to a slidable push-button


20


, via a flexible connector


22


. As shown in

FIGS. 1 through 6

, the flexible connector is an articulated endless chain formed by plural beads or small balls strung on a thread or string. As shown in

FIG. 7

, the flexible connector is a flexible wire.




Each push-button


20


comprises an enlarged external section


24


located on the external surface of panel


10


, and an internal neck section


26


extending through a relatively narrow slot


28


into the aforementioned slot


18


. In the embodiment of

FIGS. 1 through 6

, internal neck section


26


of the push-button has a circular opening


30


that receives the upper run of flexible chain


22


. The lower run of chain


22


extends within a narrow trough


32


that communicates with slot


18


. Chain


22


extends loosely through the standard circular hole


17


formed in key


16


, such that chain


22


forms a flexible connector between the key and push-button


20


.




Push-button


20


can be manually moved along slot


28


between the two limiting positions shown in FIG.


1


. In one limiting position of the push-button, the associated key


16


is fully withdrawn from the storage panel


10


. In the other limiting position of the push-button, the associated key is fully enclosed in storage panel


10


.





FIG. 2

shows push-button


20


in an intermediate position (approximately midway between the two limiting positions). Rightward movement of the push-button, from the

FIG. 2

position causes the push-button to exert a pushing force on the associated key


16


, whereby the key is forced substantially out of slot


18


. At that point the key can be manually grasped and pulled entirely out of storage panel


10


to the exposed condition depicted in FIG.


1


. Chain


22


is long enough that the exposed key can be manually manipulated in a lock without interference from panel


10


.

FIG. 4

shows the key fully exposed.




Push-button


20


can be retracted leftwardly to pull the key back into slot


18


. When the push-button is pulled to the limit of its motion in the leftward direction, the key is fully enclosed in panel


10


; flexible connector chain


22


is in a taut condition. Push-button


20


can be retained in its retracted condition by any suitable mechanism, e.g. frictional detents located on the edges of slot


28


.





FIG. 7

shows a second form of the invention, wherein the flexible connector


22


is a flexible steel wire. The right end of the connector wire is anchored to a plug


40


that is frictionally seated in hole


17


of key


16


. The wire extends freely through a hole


30


in push-button


20


. An enlargement


42


on the wire provides a drive connection between the wire and the push-button.




When push-button


20


is moved from the

FIG. 7

retracted position, there is no movement of key


16


until the push-button contacts the key. When the push-button reaches the dashed line position, further rightward motion of the push-button forces key


16


out of the key storage panel


10


. Wire


22


serves the same function as chain


22


in the

FIG. 1

embodiment. When push-button


20


is moved leftwardly to the retracted position, wire


22


pulls the key


16


to the

FIG. 7

enclosed position.




In both forms of the invention the push-button is connected to key


16


by a flexible connector


22


that has a lost motion connection with the push-button, such that the key is spaced from the key storage panel


10


when it is fully exposed. The exposed key can be freely manipulated while still being connected to the key storage panel.
