No. 857,409 s claims. (ci. 70-456) This invention relates to a key holder, and has for an object to provide a device for holding one or more keys in such a way that any individual keyl may be easily selected and shifted from an inoperative or retracted position within a housing or casing to a position for use, and then after use may be easily and quickly shifted back to its inoperative position in the casing.
Another object is to provide a device of this character in which the holder comprises a body or casing in which are pivotally mounted a plurality of key supports each individually shiftable from a retracted position within the casing to a position outside the casing by a spring, and which support is provided with means for pivotally mounting a key in the support, said support including a swivel member pivotally mounted in the casing, and an arm provided with means for pivotally supporting the key and swivelly connected to the swivel member to permit swinging of the key laterally to any desired position, and there is a manually operable releasable latch for each key support to maintain it normally locked within the casing, including means on the swivel member for retaining the latch in its retracted position when the key support is in its extended position to permit use of the key. Y
Another object is to provide an improved structure for a device of this character including a body member forming a casing or housing which may be molded from a suitable plastic material, including means for pivotally mounting the key supports and forming guideways for the releasable manually operable latch, together with means for mounting anchor means for the springs operating the key supports.
With the foregoing and other objects in View, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.

The device shown comprises a body member in the form of a housing or casing 1 formed of two members 2 and 3 preferably molded of some suitable plastic material, the member 2 comprising a rear memberl including a rear wall 4 and convexly curved side or edge walls 5 and 6 extending at right angles thereto, and the member 3 in the form of a plate forming the front wall of the casing and closing the open side of the rear member Z. The front wall or plate 3 may be secured to the free edges of the side walls 5 and 6 by cementing or other suitable means, preferably by providing the edges of the walls 5 and 6 with blind openings or recesses 7 and a groove 8 to receive dowel pins 9 and a rib 10 molded as a part of the front plate 3, seating in these openings and groove and cemented therein to eiectively secure the plate 3 to the rear member. These two members Z and 3 provide a casing or housing which is closed on all sides except at its upper end which is open as shown in FIGS. l, 2 and 4 to permit key supports and the keys carried thereby to be swung from the retracted or inoperative position within the casing to an extended position outside the casing to permit use of the keys carried by the supports.
In the device shown in the drawing there are two key supports 11 pivotally mounted side by side in the casing, but it will be understood that the device is not restricted to use with this number of keys, as it may be constructed to carry any desired number, either one or more. Each key support comprises a swivel member 12 and an arm member 13 swivelly connected to the member 12. The swivel member 12 is preferably made of sheet metal bent to substantially U shape, as shown in FIG. 7, including aV stop shoulder 14 at one side with a curved edge 15 extending backwardly from this shoulder. The shoulder may be formed by lugs 16 bent inwardly from the edges of the side members. The side members are each provided with a pivot opening 17 for pivotally mounting the support within the casing 1. This swivel member is also provided with a tubular extension 18 and the arm member 13 is provided with a similar tubular extension 19 in alignment with the extension 13, and they-are connected by a swivel pin 20 provided with tapered end portions 21 inthe tubular extensions 18 and 19 with a portion of the tubular extensions crimped about the tapered end portions 21, as shown at 22, thus providing a swivel connection between the -arm member 13 and the swivel member 12, which will permit the arm member 13 to be swung laterally about the swivel connection. The arm member 13 is also preferably made of metal bent to substantially U shape, as indicated in FIG. 6, between which a key 23 may be pivotally mounted to permt it to be swung to any desired position in use. Any suitable means may be provided for pivotally mounting the key between the sides of the arm member 13, but a satisfactory and eil'ective simple means is to provide the side walls with inwardly pressed dome-shaped extensions or lugs 24 adapted to seat in the opening in the key handle from the opposite sides thereof. The resilient action of the side members 13a will permit them to separate or move apart sufficiently to permit a key to be inserted between these side members and then spring back to seat the lugs 24 in the opening in the key handle and provide a pivotal connection between them. For the same reasons a key may be readily removed for substitution of another key.
Any suitable means may be provided for pivotally mounting the key suport 11 within the casing, but a simple and eiective means is to mold an inwardly extending lug or pin `25 on the inner side of the rearwall 4 of the housing and provide a bearing sleeve or bushing 26 to enclose this pin and provide a bearing `for the swivel member 12 as it is passed through the opening 17 in this member. Its free end and the Ifree end of the sleeve may be `supported by being recessed in the the inner Surface of the front face 3, as shown at 27 in FIG. 4, and the opposite end recessed in the wall 4 as shown at 27a.
A manually operable releasable latch is provided for retaining each key support 11 and the key carried therebyrwi-thin the casing or housing, as shown in full and dotted lines in FIG. l and full lines in FIG. 2.. AThis latch comprises a block 28 mounted to slide wit-hin the casing. It is in the form of a rectangular lblock guided between spaced parallel side walls 29 and 30 molded on the inner surface and integral with the rear wall 4. This block is provided with a serrated lug 31 projecting through a slot 32 in a side wall of the casing where it is accessible for ope-ration by a thumb or nger of the user. In the device shown there are two key supports 11 mounted side by side on the pivot stud 25, and when in the retracted position within the casing the swivel connection between the swivel member l2 and the arm member 13 and the connecting portions between the side walls of these members, lie just within the 'free edges of the side walls of the casing at the open upper end thereof, as shown in FIGS. l, 2, 3 and 4. The latch 28 is so arranged that when the key supports 11 are in this position the shoulder I4 on the key support engages one side of the latch 28, as shown in FIG. l, to thus retain the key support I1 and the key carried thereby in the retracted or inoperative position within the casing. This retains the key support in this position against the action of a coil spring 33 connected at one end 34 to the swivel member 12 and at its other end 35 to an anchor plate-36 .mounted within recesses 37 molded within the casing. This spring is stressed or biased so as to tend to swing the key support 11 and the key carried thereby from its retracted or inoperative position within the casing through the open end thereof to an extended or operative position, as shown at the top of FIG. 2. This action is permitted by shifting of the latch 28 downwardly from its position in front of the shoulder t4 on the latch member 12, as shown vin full lines in FIG. 2. As the key support il is swung outwardly by the spring 33, after being released, the curved edge walls I of the swivel member 12 move into a position over the end wall 28a of the latch Vmember 28, as shown in FIG1 2, and retain this Vlatch in the released or retracted position while the key support Il is swung outwardly to its extended or operative position. The latch 23 is held in this position by a kcoil spring 38 located between the opposite end of the latch 28 and the wall 39 connecting the walls 29 and 30.
The anchor plate 36 is preferably a rectangular sheet 0f metal, as shown in FIG. 9, and it is lanced to provide lugsA which are bent laterally from the plane of the plate providing an open hook 41 over which a loop 3S in the end of the spring 33 may be passed to connect the spring to this anchor plate. It will be seen from FIG. 4 that as there are two key supports 11 pivotally mounted side by side within the casing, and there is a spring 33 vfor each key support, there will be two of these lugs 40 on the plate 36, one for each spring. Also there will be a slidable latch 28 for each key support, and with two keys these two latches 4will -be reversed so that the serrated lug 31 of one will project through the slot 32 in the rear wall 4 of the casing, while the serrated nger grip 31 of the other will project through a similar slot 32a in the Ifront wall 3 of the casing. This will provide a simple way of permitting the user of the device to readily select whichever key he desires to be used, `as the release latch for one key holder is on one side of the housing or casing and the operating means for the other latch is on the opposite side of the casing.
It will be'seen from the above that this provides a very SimpleY and edeetive means of mounting one or more keys in a casing or housingy in such a way that they may be readily swung from an inoperative or retracted position enclosed within the casing or housing to an outer or operative position automatically upon mere release of the movable latch or catch-23; also that by means of the swivel connection 20 the key may be readily swung to any angular or lateral position after being swung out of the casing. VAfter use the key and its support may be readily and easily shifted back from its extended or operative position into the casing where it is effectively enclosed, but always ready for instant use by mere release of the latch or catch Z8; also that when the key support il is in its extended or operative position the spring biased latch 2S lis automatically retained in its retracted or released position by means of the curved edge walls i5 of the swivel member 12, so that when the key support I1 is swung back'to its enclosed position within the casing this latch is automatically shifted by the spring 38 into its-holding position in front of the shoulder 14 on the swivel member 12. It is to be understood the housing or casing may be of Vanyrsuitable shape. In the embodiment shown as there are -only two keys side by `side, an effective and satisfactoryA shape is that shown, which is substantially triangular, with convexly curved side edges 5 and 6, but it will be understood other shapes may be employed if desired. If it is desired to use a casing open at opposite ends with keys side by side to be swung outwardly from each end, the casing may be, for example, substantially rectangular and open at both ends.
Having thus set forth the nature of my invention, I claim:
