Description




TECHNICAL FIELD OF THE INVENTION




The present invention relates to a key holding device for holding multiple keys. More particularly, the present invention relates to a key holding device having multiple compartments to store and easily access keys for use.




BACKGROUND OF THE INVENTION




There are numerous key storage cases designed for carrying in a purse or pocket. These key cases often contain a housing having multiple slots to store a key; however, there are numerous disadvantages with these configurations. For example, if the user desires to have a key case capable of storing multiple keys, the devices become bulky and inconvenient to store in a pocket or purse. Additionally, many key holding devices are difficult to open and close and require the use of two hands and excessive manipulation to separate the desired key, then to turn that key with the cut side up or down to fit inside the desired device. This is especially burdensome when a user is carrying other objects and has only one free hand to access a key.




The present invention is designed to overcome these disadvantages by providing a key case capable of holding multiple keys in a compact fashion so as to allow the user to easily and comfortably carry such devices in a small purse or a pocket having simple operation.




SUMMARY OF THE INVENTION




The present invention relates to a key holding device whereby a multiplicity of keys can be stored inside a key storage area. Each key is stored in a separate compartment, cut side up or down as needed, and is attached to the device by use of a hanger assembly. The hanger assembly includes a clasp attached to a key and a strap to connect the clasp and key to the key holding device. The hanger assembly allows the user to place the key between a storage position, where the key is locked inside the key holding chamber, and a use position, where the key is freely positioned outside the chamber in order to be inserted into the desired device.




While in the storage position, a user can disengage a locking mechanism, which locks and holds the key inside the key holding chamber. Once unlocked, the hanger assembly and key can be pulled outward until the key is completely removed from the key storage area. At this point, the key can be pivoted and rotated for insertion into the desired device. A biasing mechanism retracts a portion of the strap inside the key holding device to shorten the exposed portion of the strap. If it is desired to remove the key from the device, a cap, located on the top portion of the clasp, can be removed thus separating the key from the hanger assembly. Upon separation, the biasing mechanism retracts the strap and cap inside the key holding device in a locked position. To re-attach the key to the hanger assembly, the hanger is pulled outward from the device and the cap is re-connected to the clasp.




After use, the key is rotated and pivoted so that it is aligned with a slot opening on the key holding chamber. Once aligned, key is then inserted inside the device for storage.




The key holding device is designed to accommodate multiple keys and can have various configurations. Keys can be inserted from the top end of the device and/or the bottom end of the device. The number of keys is directly related to the desired size of the overall case.

31


are inserted in the aligned openings to fasten housing walls


14


and


16


together to prevent separation. Threaded opening


26


and


28


protrude outward from housing walls


14


and


16


into chamber


12


and are of sufficient length so that exterior annular ridge


30


fits inside interior annular ridge


32


to provide a snug fit when assembling housing walls


14


and


16


. Tubular threaded openings


26


and


28


are formed along the outer edges of chamber


12


to prevent interference when storing keys inside chamber


12


. A cover


34


is placed inside cavity


35


and is attached to housing walls


14


and


16


to cover openings


26


. Cover


34


is preferably fabricated from a flexible material and can be clear so that a small photo or other writing can be placed inside cavity


35


and covered by cover


34


.




In a preferred embodiment, end cap


18


is placed on the top end


36


of storage area


12


and a bottom cap


20


is placed on the bottom end


38


of storage area


12


. End cap


18


contains multiple slots


40


which are used to guide keys


22


inside storage area


12


. Slot


40


is formed by slot side boundaries


42


which have sloped or “v” shaped configurations in order to allow the user to grasp and unlock the key from the storage area (discussed in detail below). Other shapes and configurations of side boundaries


42


can be used including for example, semicircular shaped boundaries as long as a sufficient opening is present to allow the user to grasp the key from the slot.




In the embodiment shown in

FIGS. 1 and 2

, end cap


18


contains four slots


40


, however, it should be realized by one of ordinary skill in the art that a greater or fewer number of slots


40


can be used depending on the desired size (i.e., the thickness) of storage area


12


. End cap


18


also includes a cross support


44


that extends across the width of slot


40


and separates the adjacent slots. In addition to separating slots


40


, cross support


44


acts as an additional support for cap


18


. Bottom cap


20


is configured to enclose bottom end


38


of case


10


and has a flat surface in order to rest key case


10


in an upright and vertical position.




In yet another embodiment, bottom cap


20


is replaced with a second end cap


18


so that additional keys


22


can be inserted inside storage area


12


from both top end


36


and bottom end


38


, as seen in

FIGS. 3-6

. In the end cap illustrated in

FIG. 2

, slots


40


on cap right side


18


R are slightly offset from openings on cap left side


18


L. Referring specifically to openings


40


on cap left side


18


L, opening


40


is offset from cap front end


18


F a distanced slightly greater than the corresponding slot


40


on cap right side


18


R. Thus, when key case


10


contains a cap


18


on each end (i.e., top end


36


and bottom end


38


), caps


18


can be attached such that keys


22


will be offset while inserted inside key storage area


12


. In this offset configuration, the key ends are prevented from contacting each other when fully inserted inside storage area


12


. End cap


18


is connected to walls


14


and


16


by placing mounting arms


46


underneath a protrusion


48


when walls


14


and


16


are connected during assembly.




A clasp


50


attaches to key


22


and contains two opposed and spaced apart sidewalls


52


separated by transverse support member


54


. Support member


54


provides sufficient clearance to insert key


22


between sidewalls


52


. Each clasp sidewall


52


contains an opening


56


for alignment with opening


58


on key


22


(FIGS.


3


-


6


). Once aligned, a left vise


60


and a right vise


62


are aligned and inserted through clasp sidewall openings


56


. Each vise is shaped to fit snug inside clasp sidewall opening


56


when properly mounted. Vises


60


and


62


contain an upper portion


64


that contains a threaded opening


66


to receive a screw


68


. Vises


60


and


62


both contain a rounded lower portion where an extension


70


is attached such that the extensions are aligned and inserted through opening


58


on key


22


to connect key


22


to vises


60


and


62


. In a preferred embodiment, extensions


70


contain a small circular cross section in order to allow attachment to any size or shape of opening


58


. As extensions


70


are aligned through opening


58


and threaded openings


66


on vises


60


and


62


are adjacent and aligned with each other, screw


68


is inserted therein to lock the vises together to prevent key


22


from separating from between sidewalls


52


.




Because key


22


can vary in thicknesses, key pads


72


are optionally mounted between left vise


60


, right vise


62


and key


22


to act as “spacers.” Spacers


66


contain a semicircular cut-out


74


along the bottom boundary for mounting above extensions


70


and have a top boundary


76


to mate with a flat ridge


78


, located on the bottom surface of vise top portion


64


. Spacers


72


are used, if needed, to maintain a fixed relation between key


22


and clasp


50


.

FIG. 2

, hanger assembly


24


attaches key


22


to key case


10


. Hanger assembly includes a flexible wire strap


80


connected to a cap


82


by a ball joint


84


. Ball joint


84


includes a spherical end


86


connected to a first end


88


of strap


80


for placement inside a cavity


90


. Clasp


50


contains a cavity


90


on the right and left side to allow the user to connect cap


82


and spherical end


86


on either side of clasp


50


, whichever is necessary. Referring specifically to

FIG. 6

, the diameter of sphere


86


is slightly larger than opening


92


to prevent cap


82


from separating from strap first end


88


. Ball joint


84


permits cap


82


to be pivotably mounted to strap


80


so that key


22


can rotate and pivot during use. Cap


82


is attached to clasp


50


by snapping cap ends


94


around clasp transverse support member


54


.




Referring to

FIG. 2

, an interior sidewall


96


forms a hollow strap compartment


98


to house strap


80


. As seen in

FIGS. 3-5

, strap compartment


98


extends the entire height of case


10


so that strap


80


can be stored therein while in the storage position (FIG.

). When in the storage position, as seen in

FIG. 3

, strap first end


88


extends outside strap compartment


98


through opening


100


. The diameter of opening


100


is slightly larger than the diameter of strap


80


so that the strap can slide through the opening (FIGS.


3


-


5


). A retainer ring


102


located on strap second end


104


prevents strap


80


from disconnecting with key case


10


when fully extended from strap compartment


88


.





FIG. 3

illustrates keys


22


stored and locked in the storage position by locking mechanism


106


. Locking mechanism


106


includes a cavity


108


, located on clasp lower end


110


and is configured to receive locking extension


112


, found on protrusion


48


located on interior of first and second housing walls


14


and


16


(FIG.


2


). Clasp lower ends


110


are fabricated from a flexible material so that as the user removes the key from the storage position, the user can insert a finger between side boundaries


42


to apply a slight forced to ends


110


to separate cavity


108


from extension


112


. This provides sufficient clearance to remove key


22


from storage area


12


.




As key


22


is removed from storage area


12


(FIGS.


4


-


5


), a biasing mechanism or spring


114


, located between opening


100


and retainer ring


102


, is compressed. Spring


114


is sized to fit around flexible strap


80


and extend from strap first


88


end to strap second end


104


. Strap compartment


98


is sufficiently sized such that the width prevents the spring from tangling or bending apart from wire strap


80


. Once the entirety of key


22


is removed from storage area


12


, the key is turned (

FIG. 4

) and pivoted (

FIG. 5

) so key


22


can be inserted into the desired device. While in the use position (FIG.


5


), spring


114


expands to partially retract strap


80


inside strap compartment


98


. The length of spring


114


, while key


22


is in the use position, is dependent upon the weight of case


10


in combination with the keys stored inside storage area


12


. This reduces the amount of slack from wire strap


80


in order to provide a more compact device.





FIG. 6

illustrates key


22


removed from hanger


24


. Removal of key


22


requires the user to disengage cap


82


from transverse support member


54


by applying a slight force to cap end


94


sufficient to deform the cap to remove it from transverse support member


54


. Once removed, spring


114


retracts strap


80


inside strap compartment


98


, as seen in

FIG. 6

, where it is locked in place.




Key case


10


can be fabricated from any suitable material such as plastic or metal. Furthermore, key case


10


can be fabricated to accommodate as few as one key, depending on the desired size.




Alternatively, cover


34


(

FIGS. 1 and 2

) can be replaced with a door to define an entranceway for a second separate compartment in storage area


12


(not shown) to store small items such as jewelry or make-up, etc. This separate compartment can used to store other accessories such as a garage door opener, a flash light, a digital clock, a car security system remote, etc. Additionally, an external pocket (not shown) can replace cover


34


so that credit cards, drivers licenses, cash and other objects can be stored.




When multiple slots


40


are used, an identifier (not shown) can be placed adjacent each slot to allow the user to determine which slot to access. Preferably, each slot is identified by a raised portion on walls


14


and


16


adjacent to each slot


40


such that when the user desires to select a key, the user touches the raised portion to identify corresponding slot


40


. Additionally, identifiers can be placed on top of hanger cap


82


.
