Feb. 23, 1954 KEY CASE Filed May 4, 1951 Allurm'y Patented Feb. 23, 1954 UNITED STATES RATENT OFFICE KEY CASE William E. Hudson, J r., Vicksburg, Miss. Application May 4, 1951, Serial No. 224,618

3 Claims.

, This invention relates to an improved construction of key case capable of containing a plurality of keys therein in such a manner that the individual keys may be moved selectively from retracted positions within the case to projected positions externally of the case for use without requiring opening of the case and without involving any movement of the keys other than the selected key to be used.

Another object of the invention is to provide a key case of extremely simple construction wherein each of the keys will be contained in a separate compartment supported by a separate operator capable of being manually actuated from the exterior of the lectively to a projected or a retracted position.

Another object of the invention is to provide a key case of rigid construction wherein the body portion of the case will form a rigid handle for each key thereby making it possible to eliminate the usual enlarged key head thus reducing the amount of material required in producing a key and at the same time making it possible to house the keys in smaller compartments of the case and thus reduce the over-all size of the case.

Another object of the invention is to provide a key case wherein a desired key may be readily selected in the dark and moved to an exposed position for use.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

. Figure 1 is a plan view of a key case constructed in accordance with the invention;

Figure 2 is an end elevational view thereof as viewed from the lower end of Figure 1;

Figure 3 is a longitudinal sectional view taken substantially along a plane as indicated by the line .'i-3 of Figure 1;

Figure 4 is an enlarged fragmentary sectional view taken substantially along a plane as indicated by the line 4-4 of Figure 1;

Figure 5 is an enlarged fragmentary sectional view taken substantially along a plane as indicated by the line 5-5 of Figure 3, and Figure 6 is an enlarged fragmentary transverse sectional view taken substantially along a plane as indicated by the line 6-5 of Figure 1.

Referring more specifically to the drawing, the improved key case in its entirety is designated generally B and includes a body portion, designated generally 9 which is preferably formed of a substantially rigid relatively light weight metal case for moving the key seincluding a front wall Ill and a rear wall I I which Walls are of the same size. The walls I0 and II are provided along o posite side edges and one end with complementary flanges which project at right angles to the planes of said walls including corresponding flanges I2 at complementary side edges of the front and rear walls which are provided at spaced intervals with aligned barrel portions I3 which are journaled on pins I4 and form hinges of the concealed type about which the front and rear walls I0 and II are capable of swinging, from the closed position of the body portion 9 as illustrated in Figure 2 to an open position for exposing the interior of said walls. The barrel portions I3 of each flange I2 are receivaole in recesses, not shown, of the other flange I2, as is conventional in hinges of the "concealed type. The front and rear Walls are also prodded with complementary flanges I5 at corresponding ends of said walls which are disposed in abutting engagement when the body portion of the case is closed, as illustrated in Figure 3. The other, complementary side edges of the front and rear walls are provided with complementary flanges I6, as seen in Figures 2 and 6, which are likewise disposed in abutting engagement when the case is closed. The key case is provided with a suitable spring latch to retain it in its closed position, as best illustrated in Figure 6, including a spring latch element I! which is preferably anchored at one end in the front wall Ill adjacent its flange I 6 and which is provided with an offset free end II! which engages around a keeper I9 on the flange I6 of the rear wall I I. Said keeper I9 constitutes an integral internal projection of said last mentioned flange I6. It will be readily apparent that the latch I I, I9 will retain the case in a closed position but will permit the case to be opened when the walls I0 and II are forcibly urged away from one another and will automatically relatch the case to a closed position as the walls It and II are swung back to their parallel positions of Figures 2 and 6. However, as the description proceeds it will be readily apparent that any suitable form of latch may be provided in lieu of the latch as illustrated as the case 3 is only opened when it is necessary to replace a key.

It will be noted that the end of the caseopposits the end thereof provided with the end flanges It is open. As seen in Figure 1, the front wall It is provided with four corresponding slots 29 which are laterally spaced relatively to one another between the flanges i2 and I6 and which extend from adjacent the end flanges I5 to adjacent the opposite, open end of the case. Each of the slots 20 is substantially "i -shaped having a transverse portion 2i at the end thereof disposed adjacent to the flanges it which extends laterally from each side edge of the longitudinal portion of its slot 26. Likewise, as illustrated in Figures 1, 5 and 6, the inner side of the rear wall II is provided with four corresponding grooves 22 each of which is also T-shaped including a transverse end or head portion 23. The

grooves

22, 23 align with the slots 29, 2| when the case is closed and as seen in Figures 1 and 5 are each of a width slightly less than the width of the slots. Also, as seen in Figures 1 and 5, the head portions M of the slots and 23 of the grooves are provided with

bottom edges

24 and 25, respectively, which are disposed at acute angles to the side edges of the longitudinally extending portions of the slots and grooves so that said edges 2d and 25 project outwardly relatively to the longitudinal axes of the slots and grooves in directions from the closed end of the case, provided by the flanges 55, and thus the head portions 2: and 23 of they slots and grooves, respectively, are flared outwardly toward each end thereof, for a purpose which will hereinafter become apparent. The front wall I!) is provided with a plurality of transversely spaced partitions wh. ii are interposed between. and: spacededual distances .slots 22 and which are disposed on the inner side of said front wall and bear against the inner side of the rear wall Ii, when the case is closed as seen in Figure 2, for dividing the case into longitudinal compartments which open outwardly of the open end or the case and each of which is provided with a slot as and, a groove 22.

A- key support and actuator, designed generally 2.8, is associated with each compartment 2'! and as best illustrated in Figure 4, includes a stem 29. having a collar to fixed therearound near one end thereof. The shorter end oithe stem which projects from one side of the collar 30*, as seen at 3|, is externally threaded to tl'lread'edly engage an internally threaded socket 32' forming a shank which projects from one side of an actuator head or knob 33. The socket 32 slidably engages the slot 23 of the co1npartmerit 21 with which the actuator 28 is associated and the substantially flat head- 33 is slidably dispcsed'against the outer side of the front wall in while. the collar 33 is slidably disposed against the inner side of said front wall and within the key chamber 21. nthreaded portion 34 adjacent its opposite end and a rounded, slightly restricted terminal portion 35 disposed beyond the threaded portion 34'. It will be readily apparent that the con nected portions 3! and 32- will retain the stem 29 and knob 33 in applied positions relatively to the front wall it] when said front wall is swung on the hinges [3, Hi to an open position away from and at approximately a right angle to the rear wall H. With the case thus in an open position, a key 36 may be applied to each compartment 2'1 and the opening 37 in the head portion of the key engaged on the intermediate portion or" the stem is over its terminal portion 35 and so that the key will be disposed against the exposed side of the collar 3t. A retaining collar 3d, forming a part of the unit 25, in the form of a fiat disk-like nut having a threaded opening, is inserted over the stem terminal 35 and threadedly engages. the stem portion St for from the '-z The stem 29 is provided with clamping the head portion of the key 36, which surrounds the opening 31, between the

members

30 and 38. The key 36 preferably difiers from conventional keys in that the head portion in which the opening 3'! is formed is no wider than the notched bit of the key since the usual key bow is eliminated in order to enable the key to be accommodated in a narrower chamber 31 than would otherwise be possible and since a key bow is not necessary in order to provide a handle portion for turning the key as this is adequately provided by the body portion 3 of the key case. Additionally, this reduction in the size of the head portion of the key which eliminates the key bow effects a considerable saving in material'in' addition to enabling the key case 8 tobe made narrower, than would otherwise be possible for holding any predetermined number of keys.

From the foregoing it will be readily apparent that after keys 3% have been applied asv previously described to the key holder and actuating units 28 the key case is latched in a closed position, it will not ordinarily again be opened until it is necessary to replace one of the keys 36. The keys 36 are normally disposed in retracted, positions within the compartments 2! and to retain the keys therein the units 28 are displaced laterally into one end of the slot head 2! and groove head 23 and so that the stem 2.3 will be out of alignment with the longitudinal portions of the slots and grooves. The, inclined surfaces and 25 of the slots and grooves assist in maintaining the stems 29 in their positions as illustrated in Figure 5 and make it necessary to move each unit 23 toward the closed end of the case in order to position the stem 29 thereof in alignment with its associated slot 2.0 and groove 22. Accordingly, an individual unit 28 of a selected key 36 can be positioned with its stem 29 in alignment with the longitudinal portion of the slot 2t and groove. 22 byinitially exerting a pressure with the thumb or finger against the knob 33 of said unit in, a direction transversely of the case 8 and thereafter exerting a pressure longitudinally of the case toward its open end for moving the selected key 33 to a projected position, as illustratedv in Figure 3 and at the left of Figure 1. The selected key may then be utilized for opening a lock and thereafter returned to a retracted position corresponding to the position, of the other three keys; as seen inFigure 1 by a thumb or finger pressure exerted. against the actuator knob 33. The associated slots and grooves cooperate to retain the actuating units 28 in correct. positions relatively to the. case and with the stems 29 disposed perpendicular to the walls in and H. Each stem terminal 35 has sufficient frictional engagement with its associated groove 22 tov retain the actuating unit 28, of which it forms a. part, and associated' key 36 in a. retracted position. Likewise, the parts 3! and 32 may be tightened to cause the collar 3t and knob 33 to frictionally engage opposite sides of the front wall IQ for accomplishing this same result. 7

If desired, the outer surfaces of the knobs 33 may be provided with suitable indicia to indicate the lock in which the key carried thereby fits; however, this is usually unnecessary as the location of different keys in the case 8 will be quickly memorized and which provides an additional novel featurev since the key case may then be efficiently used in the dark as the position of the knobs 33 with respect to the closed and open ends of the body portion 9 will readily indicate to the owner the identity of the key associated therewith so that any selected key may be moved to a projected position in the dark.

Obviously the size of the key case 8 may be varied to accommodate a greater number or fewer keys than as shown in the drawing and various other modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.
