Claims.

' V The present invention relates to a device for holding a plurality of keys in a loosely assembled relationship so that any one of the keys may be selected and moved to a position outside the case for operating a lock. The invention further pertains to an electric lamp mounted on the key case with the lamp bulb being adapted to be energized when one of the key holding clasps is moved to a position outside the case.

An object of the invention is to provide a battery and lamp bulb in association with a key case so that when one of the clasps holding one key is moved to a position outside the case with the key in a position to operate a lock an electric circuit is completed to energize the lamp bulb which may then be used to illuminate the key hole in which the key is to be inserted.

Another object of the invention is to mount a battery supplied lamp on a key case which includes two electrical conducting elements insulated from each other with one element supporting key clasps which serve as switch members adapted to engage a rib carried by another part of the key case structure so that the key clasp will be maintained in an extended position bridging an electric circuit for supplying current to the I lamp bulb.

Other objects and features of the invention will be apparent as the present disclosure proceeds and upon consideration of the accompanying drawing and the following detailed description wherein an exemplary embodiment of the invention is disclosed.

In the drawing:

Fig. 1 is a perspective view of a key case and electric lamp organization exhibiting the inven tion and showing a flap of the key case in the open position.

Fig. 2 is a fragmentary exploded perspective view of the parts for mounting the key clasps which also form a housing for the battery.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 5.

in section.

Fig. 6 is a fragmentary sectional view showing A one of the key clasps in the extended position.

The present invention is directed to a device for automatically energizing a lamp bulb when a clasp holding one or more keys is moved to position a key outside the key case. The clasp serves as a' switch and the lamp bulb is lighted when the key clasp is in the extended position. The lamp is so arranged as to direct its rays in the same general direction as the selected key and may be used to illuminate a key hole in which the key is to be inserted. The general organization and structural elements of a device embodying such features is illustrated in the drawing wherein l l represents a key case which includes a plurality of key holding clasps 9 and ID. A flexible sheet is provided which is adapted to be folded over and. cover the clasps 9 and Ill. The flexible sheet is generally rectangular shaped and a flap portion thereof is of such length as to overlie the key clasps in a closed position and to maintain the key clasps within the case. The flexible sheet may be formed of a two-ply construction having an outer layer l2 of leather or the like and a fabric liner I4 is stitched to the facing sheet l2 around the perimeter thereof, as shown in dotted lines in Fig. 1. A portion of the flexible sheet material is adapted to embrace the flashlight housing for the battery as hereinafter described and to secure the case to the lamp structure and at the same time to provide a pleasing external appearance for the assembly.

A conducting member in the form of a metal plate I6 is provided within the key case. The plate IB is provided at one edge with a plurality of loops I'I spaced from each other as shown in Fig. 2. The loops 1'! provide means for mounting the key clasps 9 and I0 so that any one of the clasps may be turned from the position shown in Fig. 5 to a position outside the key case. It is for this purpose that the clasps are secured in notches [8 between the loops I? by means of a pin IS. The plate It is flat throughout the portion lying in the key case proper but this plate has an integral part 22 (Fig. 2) which is bent in cylindrical form so as to form a tubular portion of a housing for a dry cell battery 23 of a conventional type. One end of the tubular part 22 extends to a position flush with an edge 24 of the flexible sheet which forms the key case.

Another plate 26 of electrically conductive material is provided which has a contour similar to the plate 16. The plate 26 is provided with a rib 2'! which is raised above the upper face of the plate 26 and extends along the edge thereof. The rib 21 may be formed by upsetting the sheet material forming the plate 26. The plate 26 carries an integral extension 28 (Fig. 2') which is shaped in cylindrical form and provides another part of the housing for the battery of the flashlight assembly. One end 3| of the tubular portion 28 terminates flush with an edge 32 of the sheet material which forms the key case. The tubular portions 22 and 28 are in axial alignment when the plates I6 and 25 are in a juxtaposed relationship. The end 33 of the tubular portion 28 is then spaced from the end 34 of the tubular portion 22 as shown at 3B in Fig. to avoid electrical contact between these two portions of the cylindrical housing.

An insulating sheet 31 is provided between the plates 16 and 26 and this insulating member may be formed of any suitable material such as fiber or cardboard having an overall shape similar to the plate 26. The insulating member 3'! is inter posed between the plates i6 and 26 asrshown in Fig. 3 to thereby avoid electrical contact between the flat portions thereof. A plurality of rivets 39 extend through openings 4! in the plate It and openings 42 in the insulating member 31 and openings 43 in the plate 26. These rivets are so constructed and arranged as to avoid placing the plate It in electrical conducting relationship with the plate 28. The rivets 39 also extend through the flexible sheet of the key case to thereby secure the plate assembly to the flexible sheet. This structural relationship provides considerable rigidity to the'flexible portion of the key case in thevicinity of the juxtaposed plates and further provide means for causing thefiap to hinge along the zone indicated at 46 in Fig. l.

A conventional type dry cell battery ll is mounted in the housing provided by the tubular portions 22 and 28 of the plates I6 and 26. The usual cardboard type sheath 48 encases the periphery of the battery 41 and prevents electrical contact of the exposed casing electrode of the battery with the tubular housing portion 23 and the tubular housing portion 22. A lamp bulb 5! having the usual type of threaded base 58 and a centerterminal 53 engages the central tip electrOde of the battery 4']. The other terminal of the lamp bulb 5! or the threaded portion 53 is maintained in electrical contact with the tubular portion 28 by means of an apertured cap member 55=removably secured in the tubular portion 28. Thus an electric circuit is established between the plate 26 and one terminal of the lamp as represented by the threads 58. The rear exposed end 59 of the battery 41 is engaged by a helical spring-6| and thisspring is engaged by and compressed by aremovable cap 62 in a conventional manner. lished' fromthe exposed end 59 of the battery 41 through the spring GI and the cap 62 to the tubular portion 22 and to the plate IS.

The flexible material forming the key case proper covers the cylindrical housing of the flashlight assembly as shown in Figs. 1 and 3. The inner layer 14 is cemented to or adhesively attached to the tubular portions 22 and 28 so as to cover the space 36. The end of the flexible material terminates at 66 as shown in Fig. 3 to provide a covering for the housing of the flashlight structure. A male fastening element 61 is provided on the outside of the covering for the flashlight housing. A female element 68 is mounted on the free end of the flap which is adapted to V engage the male part 61 when the flap is hinged about the zone 46 to thereby close the key case.

The clasps 9 and Hi are in electrical contact with the plate 16 and accordingly carry the potential of the rear end 59 of the battery 41. Thus An. electric circuitis thereby estabwhen one of the clasps I0 is swung to an outward position a portion of the clasp adjacent the hinge thereof will engage the rib 21. The rib 21 and the plate 26 are in electrical circuit relation with one terminal of the lamp bulb 5| and accordingly a circuit is completed from the battery through the lamp bulb. Thus the bulb 5| is energized. The lighted lamp may be used for any purpose and particularly to illuminate akey hole in a dark area or at night. When the clasps ID are in the position shown in Fig. 5 the circuit to the lamp bulb is open and the bulb remains deenergized.

Each of the clasps ID are provided with a lug l I. This lug is formed of an integral part of the metal strip which forms the clasps and occupies the position shown in Fig. 4. The lug H is adapted to engage the rib 21 and complete the circuit to the lamp bulb. The lug is resilient and so constructed as to pass over the highest point of the rib 27 so that the lug Il may occupy a position inwardly beyond therib 2! as shown in Fig. 6. Thus the clasp remains in a releasable outer position to avoid temporary interruption of the circuit from the battery 41. A notch'8l is provided in the plate 26 So that when the clasp 9 is swung outwardly the lamp is not lighted. When the clasp 9 is moved to the outward position any one of the other clasps ill may be utilized to bridge the circuit for energizing the lamp 5| to illuminate the key hole in which the key on the clasp 9 is to be inserted. Thereafter the key clasp it used to energize the lamp may be returned to the position shown in Fig. 1 after the key on the clasp 9 has been introduced into its key hole. The fla in the closed position maintains any or all of the clasps in a retracted position to avoid energization' of the lamp circuit.

While the invention has been described with reference to specific structural features and with regard to one general organization it will be appreciated that the invention is directed to automatically energizing the lamp when a key clasp is moved to an extended position from the case. Various changes and modifications may be made in the details as well as the organization of the elements without departing from the spirit and scope of the invention as set forth in the appended claims.
