Description

apertures 26 in the plate I4, with the portion of the shank below the plate I4 split and bent over to secure them in place with the axes of the openings through the rings vertical to the center line of the case. If the bent-over portion of the shanks appearing at the back of the case are objectionable, it will be understood that the rings may be soldered or welded to the plate I4, thus keeping the back of the case clear of projections.

These rings carry key hangers 28, all of which may be identical. Each key hanger comprises a length of spring wire shaped to form a loop 38 at its center. This loop extends through one of the rings I8, 20 or 22 and hinges the hanger to the case. Adjacent the loop 30, the spring wire is shaped-to provide a slightly bowed apart portion 32 which tightly embraces a knob 34, one 'of which is positioned directly in front of each of the rings. This knob 34 is riveted, soldered, or otherwise suitably secured to the plate I4 and in conjunction with the bowed portion 32 serves to hold the hanger 2 8' tightly against the bottom of. the case, since the compressing force oi the spring wire against the shoulder of the knob tends to urge the hanger downwardly.

From its position in front of the knob 34 both ends of the spring wire are bent to`forrn a U- shaped portion. The ends of the legs of the U are then bent upwardly andV backwardly to 'form hooksY 36 to embrace the'lower shoulder of a key bow with the extreme end of the bow lying within a trough 38', the ends of which are spot welded or otherwise secured in a. suitable manner to the legs of the outwardly bowed portion ofthe U.. The trough 38 may be, and preferably is, formed as a metal stamping.

Preferably, the hooks 36 approach each other quite closely when at rest so that they will grip the key bow tightly'when forced apartl to receive the key.

The Wall I6 immediately adjacent the rings I8, 20 and 22 has slots 40tl`1erein. These slots provide an opening so thatwhen a key' is lifted from they case and moved about the hinge, formed by the loop 30 and ring 20, for instance, into its outwardly projectingposition, the narrow portion of the` hanger between the loop 38 and bowed portion` 32Y can extend therethrough. With the key in this outward position, it will be apparent that the case can be closed.

T'o hold the bits of the keys slightly spaced from the bottom of the tray in a position to facilitate their being lifted and moved outwardly, aV key rest bar for rib 42 is provided. rib extends transversely of the tray and may be either a separate piece secured to the plate I 4 or it may be made by indenting the plate 'I4 from the opposite side, as shown in Fig. 2.

The tray I0,`just described, and the tray I2, which, as has been explained earlier, is its reverse complement, are joined in a well-known manner by spring biased hinges 44 so that when the case is open it Ywill lie as shown in Fig. 1. When closed, the two trays lie face to face with the keys and. key hangers inside. In its closed position the case is secured against opening by a snap catch 46 which may be provided in any well-known manner. In loading keys into the case, the hooks 36 are spread apart suiiiciently to allow the shank of the key to be placed therebetween, and the bit of the key pulled outwardly against the tension of the spring wire until the end of the key bow slips into the trough 38. The keyris then swung over into the case until the bows 32 slip over and embrace the knob 34. The compression of these bows 32 against the knob holds the key bit securely against the rest bar 42 and prevents jangling. With the keys in this position the case may be snapped shut.

When a key is desired for insertion into a lock, the snap catch 46 is pressed, thereby allowing the case to spring open. The thumb or a nger of the same hand may then be used to lift the bit of a key and flip the key outwardly, whereupon the case may be closed with the key extending therefrom.

To return the key to the case, the case is opened, the key flipped back into the case and pressed downwardly until the bows 32 snap over the head of the knob 34.

From the foregoingit will be seen that the case may be manufactured at relatively low cost, is neat in appearance, prevents jangling of the keys, and may be conveniently operated in the dark. 'by the use ofL only one hand even though. the tactile sense of the individual is not highly' developed.v

In the embodiment of this invention illustrated in Figs. 3; 4 and 5, .the case maybe similar to the one above described,v excepting for the key hangers andthe-means for rsecuring the keys againstv the key rest bar when the keys are within thez case.

rI'he hanger, as Vshown in Figs. 3 and 4, comprises a crescent-shaped trough 53 similar to the trough 38 but provided with an extension 52 having a ring 54 to link through the ring 20a; This ringk 23a is similar to the ring 20 described in the earlier referred to embodiment. Between thetrough 53 and the ring 54 the extension 52 is'provided with a narrow neck 56. This neck is adapted to be pressed between two spring clips 58 secured to thel backv plate I4a to hold the hanger against the bottom of the case. Thus, the narrow neck 56 and .spring clips 58 serve much the same purpose' as the bows 32 and knob 34 in the embodiment shown. in Figs. l and 2.

The trough 50: has a spring wire U-shaped member 60 secured therein at its midportion and extending at each end to underlie a key bow. The ends of the spring wire are formed into eyes 62 positioned at approximately the shank of a key when the extremity of the key bow lies within thetrough 50 and the eyes are drawn downwardly somewhat against the tension of the spring wire. A second shorter U-shaped spring member 64 with eyes 66 at each end is adapted to lie above a key bow with its eyes 66 registering with the eyes 62. With the two spring members in this position, pins 68 extend through adjacent eyes and are riveted over to connect the two spring members.

In loading a. hanger of the above-discussed type, the key bit is slipped between the two spring members 64 and 60 until the lower shoulders of the key bow abut against the pins 68. With the keyl in this position the bit is pulled outwardly until the extremity o the bow slips into the trough 50. With the key thus secured in the hanger the device is used in much the same manner as the case illustrated in Figs. 1 and 2 and described previously.

The key case shown in Figs. 6, '7 and 8 is much the same as those above described, but is smaller inasmuch as it is designed to hold only two keys. The case, denoted generally by the numeral 10, consists of two hinged together oblong trays 12 and 'I4 with well-rounded ends. These two trays,

is adapted to contain keys while the other tray 14 acts merely as a cover for the box.

The tray 12 is provided with rings 16 and 18 at opposite ends which are linked to key hangers 80 and 82. 'I'he distance between these rings is con-- siderably less than twice the length of a key, since the keys are arranged obliquely within the case with their bits spaced apart and lying side by side. At each end of the case a portion of the side wall is cut away at 84 to permit outward movement of the key hangers.

The key hangers 80 and 82 are somewhat difier-ent from those previously described and it will be understood that they may be substituted in the case shown in Fig. 1 in the place of thosethere shown. Their particular advantage is that they hold the ends of the key bows closer to the rings 16 and 18 and thus enable the use of a smaller case. The hangers consist of a flat plate 86 of spring metal to underlie a key bow and Which has an eye 88 at one end to link through the rings 16 and '18. The other end of the plate 86 is bent upwardly at 90 and backwardly upon itself at 92 to form a spring clip 94 to press the bow of the key against the backing plate 86. The upwardly bent portion of the hanger between the points 90 and 92 is provided with a slot 96 to accommodate the shank of the key, as shown in Figs. 6 and 7.

'I'he key is inserted in this retainer by placing the key bit in the slot 96 from above and pushing the key downwardly as far as it will go. To prevent the key from working loose, the surfaces of the plate 86 and clip 94 in contact with the key may be roughened or provided with small points.

'I'he back of the plate 86 is provided with half of a snap fastener |00, the other half |02 of which is secured to the licor of the tray 10, so that when the key is within the case these snap fasteners can be interlocked to prevent jangling of the keys. It will be seen that this snap fastener serves much the same purpose as the clips 58 and neck 56 or the knob 34 and bows 32 used in the earlier described embodiments of this invention. f

In the embodiment shown fractionally in Fig. 10, the case is similar to that shown in Figs. 6, '7, and 8, excepting that here the male member |04 of the snap fastener is secured to the key hanger 86 and projects through a. small hole |06 in the back of the case. With this arrangement, the end of the member |04 provides a knob or button on the back of the case which can be pressed with the linger to separate the two halves of the snap fastener and permit the key to move outwardly. Since, with this embodiment, it is not necessary that the bits of the keys be elevated into a position where they can be grasped, the key rest bar may be dispensed with.

Fig. 9 shows an alternative space saving arrangement of two keys within a small case. In this case |08, which is generally triangular with rounded co-rners, both keys are hinged along one edge and lie obliquely within the case. This arrangement of the keys provides suicient room at one end of the case to accommodate the bows, while the' bits are brought close together to enable the case to be' made progressively smaller toward its opposite end. Here, as in the embodiment shown in Fig. 10, it is not necessary that a key rest bar be provided to elevate the key bits into a position where they may be easily grasped, inasmuch as apertures |0 are provided in the back of the casethrough which a linger `may be projected to free the two -halves of the snap fasteners and push the keys outwardly.

- It should be understood that although for purpose of illustration I have described certain specific embodiments of my invention, I contemplate that reasonable departures may be made therefrom without departing from the scope of this invention.
