Filed Feb. 12, 1965, Ser. No. 432,159 8 Claims. (Cl. 150-40) This invention relates to devices which accommodate a plurality of keys therein and which, ordinarily, are carried in a users pocket or handbag. The present invention is an improvement over the key holder disclosed in my Patent No. 2,291,896, dated August 4, 1942.

It has been found that a key holder as disclosed in said patent is unsatisfactory in some respects and so costly to manufacture that it cannot be competitively marketed.

The principal objects of the present invention are to provide an inexpensive key holder for holding plural keys and capable of being readily opened to uncover and present any selected one of the keys for use without un covering any of the other keys; to provide for the uncovered key to be pivotable relatively to the holder in use; to provide simplified but improved means for attaching keys to the holder; and to enable a user to uncover a selected key for use under guidance solely of the sense of touch, such guidance being, of course, available from the sense of sight where light conditions permit.

The foregoing and other objects, which will be apparent from the following description, are attainable from the present invention of which a preferred embodiment and several variations thereof are illustrated in the accompanying drawing without, however, limiting the invention to said embodiment and variations.

In the accompanying drawing:

FIGURE 1 is a perspective view of a key holder according to the mentioned preferred embodiment with one of plural keys, carried by the holder, in extended position in readiness for use in the lock which it is designed to open.

FIG. 2 is an elevational view of the interior of the holder; a front half of the holders casing (as viewed in FIG. 1) being omitted to disclose details of the inside of the device.

FIG. 3 is an enlarged, transverse sectional view of the device, substantially on the line 33 of FIG. 2, but including both halves of the casing and showing one key compartment cover as hingedly swung open briefly toward open position to enable the key in that compartment to swing out to its FIG. 1 and FIG. 2 position for use.

FIG. 4 is a plan view of a compartment-dividing plate blank of sheet metal or other suitable relatively rigid sheet material.

FIG. 5 is an enlarged, sectional view, substantially on the line 55 of FIG. 2 showing the compartment-dividing plate sandwiched between two identical halves of the devices casing and being held thus by two rivets or grommets.

FIG. 6 is an enlarged, sectional view, substantially on the line 66 of FIG. 2.

FIG. 7 is an enlarged, sectional view, differing from FIG. 5 only in showing projecting studs of each half of the casing employed instead of rivets or grommets as means for holding the casing halves and the compartmentdividing plate together.

FIG. 8 is an exploded, endwise elevational view of the device, including the grommets of FIG. 5, but omitting hangers provided for the keys.

FIG. 9 is a similar exploded view 'but showing the stud means of FIG. 7 for holding the casing halves and the backbone plate together.

The illustrated preferred embodiment comprises, as its principal parts, a relatively rigid mounting plate- 10, key

hooks or hangers 12, carried by the mounting plate for pivoting and rotation relatively thereto a casing or key enclosure 14 which, with said plate, forms separate compartments for separate keys, and means for securing together two similar elements 14a, 14b, of said casing with the plate 10 sandwiched therebetween.

The plate 10 is oblong and generally fiat and preferably is of sheet metal, although it may be of other suitable sheet material such as, for example, relatively stiff plastic material. In an initial step in its manufacture, the sheet metal plate'is a flat blank 10a approximately of the form shown in FIG. 4. This blank is conventional as to its form both with respect to a transverse central line a b and with respect to a longitudinal central line 0 d. The plate is formed with four similar cutouts 1012, four side ears 10c, and four pairs of end ears 10d, given the character of pairs by slots 102 which open, at their outer ends, at the periphery of the blank and terrninate, at their inner ends, in enlarged openings 10 Additionally, the plate is formed with two circular holes 10g through which extend certain holding means, in a complete key holder, to hold the plate 10 and the casing 14 together, as hereinafter explained.

The plate 10 is given its final form by deformation of the

ears

10d and 10c of the blank from the main plane of the blank 10a.

diameter than the width of the slots 102.

The ears 10d at the top of the plate 10, are rolled into loops or hanger retainers 16, the loops at the top of the plate being rolled rearwardly or rightwardly, as in FIGS. 2 and 6, respectively, and those at the bottom of the plate being rolled forwardly or leftwardly, as in the last-mentioned figures. In forming these loops, the ears 10d of each pair are maintained in parallelism so that the slots 10e are maintained of uniform width; and the ends of the ears 10d come into contact with or close relationship to the flat part of the .plate 10 to close the slots 10e.

The ears of the blank 10a are deformed as shown in FIGS. 2 and 3 to constitute them as striker members 18 of latch arrangements hereinafter described. These ears, at the lower part of the blank, are bent forwardly as the striker members 18 as in FIG. 2, or i.e., downwardly as in FIG. 3. The corresponding ears, at the upper part of the blank, are bent rearwardly as shown in broken lines in FIGJZ. As may best be undesrtood from FIG. 3, the extremities of the ears forming the striker members 18 are folded inwardly to provide smooth, rounded latching surfaces 1811 at the outer ends of said members.

The key hooks or hangers 12, as illustrated, are all like and each is in the form of a loop 12a of thin wire-like spring material such as, for example, steel, the ends of the spring material being in yieldable interengagement :and being enlarged to form an enlarged, pivotal member 12b. The loop 12a converges to form a neck portion 12c adjoining the pivotal member 12b, this neck portion being thinner than the width of slots 10e.

The pivotal member is shown as a ball which is of slightly less diameter than the diameter of the enlarged opening 10 of its related hanger retainer 16 and of greater This permits the key hanger 12 to be attached to the retainer 16 merely by inserting the pivotal member into the enlarged opening 10 and then sliding the hanger around the retainer with the pivotal member 12b within the retainer, the

neck portion 12c extending through the slot Ne, and the loop 12a outside of the hanger retainer. As is hereinafter explained, the various parts of the key holder are the use of-the device orin holding the parts of the device together. These two elements need differ only in some identifying characteristic by means of which a user of the device may distinguish between several key compartments thereof. For convenience, the difference just mentioned is ignored herein, in referring to the element 14a and 14b as substantially identical.

As the casing elements 14a and 14b are substantially identical in the sense indicated, the following description of element 14a, applies to element 14b. These two elements, preferably, are molded of plastic material such as, e.g., polypropylene, largely because of the facility of this specified plastic material hingedly to bend back and forth an almost infinite number of times without breaking.

Referring to the casing element 14a, it has a main wall 140 which, when the device is closed, is flat. The periphery of this main wall merges into integral side flanges 14d and pairs of integral top and bottom flanges 14e. The elements 14a and 14b, like the plate 10, are conventional as to form, both with reference .to a transverse central line w x, and with reference to a longitudinal central line y z (FIG. 1).

Centrally of the casing element 14a and extending longitudinally thereof, is a mounting portion 14 cmprising an outer wall 140', coplanar with and shown as a part of the main wall 140, inner, end blocks 14g adjoining and preferably integral with the outer Wall 14c, and a center block or post 1412, also preferably integral with the wall 140'. Although, within this invention, the blocks 14g and 14h may be unified or continuous as a single longitudinally extending stiffening member, it is advantageous to have them separate, as indicated, to provide intervening interior spaces 20 for a purpose hereinafter explained.

It may be seen, particularly by reference to FIGS. 2, 3, and 6, that the casing elements 14a and 14b are substantially dish-shaped so that the casing walls 14c, the

flanges

14d and 14e, the mounting portion 14 and the plate 10, defiine therew-ithin four identical key compartments 22. It is to be noted, also, that the plate 10, in the illustrated embodiment, is enclosed within the casing 14 and that the key hangers 12 and, of course, keys carried by said hangers, are in separate compartments 22.

The main walls 140 are scored, at their inner faces, along parallel, longitudinally extending lines to form hinges 24 in the casing elements 14a and 14b, which hinges give adjacent portions of said elements the character of swingable doors or key compartment covers 26. The side flange 14d are formed with integral, inturned lips 28 which coact with related striker members 18 as a latch 'arrangement, as best shown in FIG. 3, to hold the doors 26 yieldably closed. The plastic of the casting 14 is sufficiently resilient to permit each lip 28 to slide over its related striker member .18 for the related door to be opened and is sufliciently stiff to oppose such opening by accident.

It should be noted that each striker member 18 is preferably longer than the related lip 28 whereby to minimize wear of the latter. Each door 26, also, is preferably formed with an integral, protruding car 30 at or near to one corner of the door and preferably quite close to the latch arrangement of that door. The ear 30 is provided to facilitate manipulation of a door so that it can be opened.

The top and bottom flanges 14a of the casing elements may optionally be formed with arcuate cut-outs 32 so that, as best shown at the bottom of FIG. 6, any one of the key hangers 12, with a key thereon to be used, may project from the device with the door of the compartment for the projected key either only slightly ajar or even comthe holes 10g of the plate 10', the grommets or rivets being headed at their opposite ends to spread into countersinks at the outer ends of the holes 14 FIGS. 7 and 9 illustrate one of various possible alternatives for the just-described grommet or rivet arrangement. According to this alternative, toward one end :of the mounting portion of each of casing elements 14a and 14b is formed an integral stud 36 and toward that mounting portions other end is provided a hole 38. When the parts of the device are properly assembled, the stud36 of each casing element extends through a hole 10g: in the plate 10 and through hole .38 of the other casing element; the ends of these studs being broadened or flattened, like a rivet head, to oppose separation of the assembled parts.

To oppose rattling of keys carried in the holder, the plate 10 and/or the inside face of each door 26 may be covered with a sound-absorbent material. As anti-rattling means, however, the doors 26, as shown in FIGS. 2 and 6, may be molded with thin, integral flanges 40, extending centrally and transversely of each door, inwardly.

from the doors inner face; these flanges being of a suitable thinness and resiliency that when the doors are held closed -by their latching arrangements, the flanges 40 gently press and hold adjacent keys motionless against the plate 10 to prevent rattling of the keys. The flanges 40 may be continuous from end to end or may consist of a series of resilient, inwardly extending fingers.

It is desirable, although not essential, that, when a key is projected from the device for use, the door of the compartment which, houses that key should be either closed or only slightly ajar. The described hinges 24 of of plastic material contribute to this desirable condition.

Even if the plastic casing elements 1 4a and 14b are molded with the main outer surfaces of their doors co planar as the doors of element 14b appear in FIGJ3, the doors after being opened manually by being swung outwardly, as the one door appears at the lower left part of said figure, may be released whereupon the opened 'door will swing toward closed position by reaction of the plastic material in the doors hinge to the distortion which that material underwent when the door was opened.

This closing, swinging movement of the door may leave the door slightly ajar and the door, then, can be manually pressed entirely closed if desired. in either the closed or ajar condition of the door, a key hanger. of the related compartment 22 and the key carried by that hanger may. remain projected from the holder, through cut-outs 32, ready for convenient use, as shown in FIGS. 1, 2, and 6.

The just described swinging of the doors to or toward their closed positions may be accentuated by molding the casing elements 14a and 14b to a condition in which the doors 26 of said elements extend inwardly of a plane coincident with the plane of the outer face. of the mounting portion 14f-as shown in FIG. 8. When the thus molded casing elements are pressed and secured together in assembling the key holder, the doors in each of said elements are held in coplanar relationship as in FIG. 3. However, asthe plastic material in the hinges of the doors affords bias of the latter toward their molded relationship, the bias of the doors has an increased tendency to swing released open doors to or toward closed positions.

As the loops 12a of the key hangers pass through holes in keys to hold the latter, said loop of a hanger extends transversely of the general plane of a key hung ,theretransversely of the general plane of a key hung thereon so that the key holder. must-provide adequate transverse space for the key and the loop of its hanger. In the illustrated embodiment, as best understood from FIG. 3,

the portion of loop 12a whichextends at one side of key protrudes into an adjacent cut-out 10b of the .plate 10, thereby minimizing the thickness dimension of the related key compartmentand of the key holder as a whole.

Somewhat similarly, as shown in FIG. 2, the spaces 20, in the mounting portions of the casing elements, accommodate portions of the wider parts of keys, thereby minimizing the width of the key holder as a whole.

To enable a user to distinguish between the several doors 26 and, hence, to know which door to open to make a selected key available for use, the upper parts of several of the doors may be given identifying markings. Thus, as illustrated in FIG. 1, a single recess or notch 40a may be formed in one door, two notches 40b may be formed in a second door, three notches 400 may be formed in a third door, and the fourth door may be left free of such notches. Alternatively, to give only one example, the four doors may each be differently formed with raised club, spade, heart, and diamond formations, respectively on their fronts.

The just-described door-identifying means are such as to enable one to select and make available a particular selected key for use, using only the sense of touch in so doing. Such identifying means, of course, enable the sense of sight to be used when sufiicient light is present.

It is preferable that only a single key 'be hung on each hanger 12. To attach .a key to a hanger, the latter is first separated from the plate by sliding it from its related slot 10e into the latters enlargement 10f and, thence, clear of said plate, the doors of the keys compartment and the directly opposite compartment on the opposite side of the holder both being manually held open during this operation. Then, by spreading the separated hanger apart temporarily at its pivotal portion 12b the key may be attached to the hangers loop portion 12a in a well-understood manner.

The hangers pivotal portion 12b is then re-inserted into enlargement 10f and, thence, along slot 10e into the key compartment to which the said hanger relates; the same two mentioned doors being manually held open during this operation. This leaves the key in its compartment available for projection from the latter for use.

It will be realized that in normal use of the key holder, only the door covering a key to be used would be opened; hence, a key hanger and the key thereon would never become separated from the device by accident or inadvertence.

In using the key holder, one would first hold it in one hand with the door which covers the desired key facing him and the ear 30 of that door disposed toward the top of the device, the mentioned notch arrangement having guided him in selecting the proper door. Then, aided by the ear 30 on thaat door, the latter is manually swung forwardly to open position and the users hand, with the key holder therein, may be sharply jogged upwardly, causing the uncovered key and its hanger to pivot up to project the selected key from the device while still attached to its hanger.

The user, to manipulate the selected key in using it to open a lock, lets go of the opened door which, by the described reaction of the plastic material in the doors hinge, then swings to an ajar position leaving the key holder compactly in the palm of the users hand to enable him conveniently to turn the key in the lock, without disturbing the position of the key holder in the users hand.

After opening the lock and withdrawing the key therefrom, the user again swings the door open, flips the key with its hanger pivotally back into its related compartment in the holder, and closes the door, pressing the latter fully to its latched position.

Although latching means have been disclosed, they may be dispensed with if the hinges of the doors or biasing means associated therewith are adequate for holding the doors closed.

It will be understood that the disclosed concepts may be practiced in various other ways without, however, departing from the invention as set forth in the following claims.
