f/VN L. 5/455,

ATTORNEY Patented June 10, 1941 STAT E S HOLDER Glenn L. Biggs, Kenmore, N. Application June 7', 1939, Serial No. 277,851 6 Claims. (o1. 70-456) The'present invention relates to improvements in an inherently simple key retaining casing to prevent diverse keys from becoming tangled or misplaced, and more particularly pertains to an ornamental and smoothly finished all-metal holder adapted to compactly and protectively carry an assortment of frequently usedkeys.

The apertured finger pieces of several keys are herein threaded in superimposed relation upon a sectionalized post pin and respectively kept spaced apart by perfected anti-rattle washers of the frictional type. These laterally resilient spacer means are arranged to thrust between a pair of independently demountable side plates of which a rounded end snugly houses the heads of several keys for selective rotation about a common pin axis.

By a convenient manipulation, any one of such interposed keys may be made accessible for use by shifting the same from its normal nested position into its operative position, whereupon the mated side plates serve as a firm grip to facilitate the turning of said one key. After withdrawal from its lock, the used key may be folded back into nested position without presenting any ragged shank edges that might otherwise Wear and ultimately tear a hole in the owners pocket. As applied to the so-called Yale style of key, my holder can be kept sufiiciently small in size and light in weight to meet vest pocket storage eeds. The instant devices are especially useful in servicing conventional automobile keys or the like, in that any one such key may by feel be selected in the dark of night and applied to a lock without defacing the escutcheon or any other adjacent body panel parts.

In addition, effective means have been contrived for extending the length of a structurally refined post pin so as to differently space my separable side plates into rigid adjustment and thereby neatly accommodate a larger or smaller number of keys to suit requirements. In addition, one of my side plates may be shifted relative to the other about a pin axis to permit of convenient key insertion or removal.

The primary object of my improvements is directed to a simple and thoroughly practical key holder assembly of the indicated character having comparatively few component parts, each capable of being rapidlyand economically fabricated on a productive scale at the minimum of labor costs.

Embodied herein are also other structural aspects designed to carry out the foregoing princip'les, all of which features will hereinafter be more explicitly set forth.

Reference is had to the accompanying one sheet of drawings disclosing a specific embodiment of my invention, and in which drawing:

Fig. 1 represents a perspective view of an operati-vely assembled key holder embodying my improvements.

Figs. 2 and 3 respectively show a bottom edge and an end view of Fig. 1 with the keys placed into nested position.

Fig. 4 is illustrative of the manner in which my superimposed side plates may be angularly shifted edgewise for key replacement purposes.

Fig. 5 details a preferred truncated conical type of resilient spacer washer, and Fig. '6 a sectional post for a'djustabl-y mounting my side plates in stepwise spaced relationship.

Fig. '7 is similar to Fig. 6 but shows a differ- 'ent type of coupling post.

As practiced herein, my key holder may comprise a pair of identical side plates Iii and H stamped from relatively heavy rustless sheet metal having their severed edges smoothly polished to prevent pocket wear. The perimeter of each such flat plate is preferably given an elongated shape having opposed rounded ends, as shown. Near one such plate end is apertured at $2 for the reception of a headed pin screw presently to be defined. Corresponding longitudinal edges of the respective plates, may be indented to constitute a thumb notch M. Alongside this same edge, each plate is further provided with a I mated marginal screw receiving aperture l5 locatedeontiguous to the other rounded plate-end, thus confining the required apertures to but two for-each-side plate.

' 'T-hese separable plates may be alignedly mounted in superimposed relation in a novel manner by the use of identical primary and secondary sectional posts or adjustable spacer pins, respectively designated in their entirety as It and i6. Each such post may comprise a series of tubular metal sections or couplings such as ll, [1, etc., disposed axially in tandem alignment with squarely abut-ting ends and being internally-threaded throughout the length L thereof. To constitute an assembled post, a plurality of said sections may be interconnected by separate headless Worms or the like 'splicer tie means such as W cut to a length substantially equal to L. The opposed fiat ends of my composite posts or key retaining pins are fixedly interposed between the assembled side plates and may have a headed post screw such as {9 inserted into each end thereof and through an appropriate plate aperture in the Fig. 6 manner. The post is purposely kept larger in diameter than the size of either plate aperture 12 or [5.

These sectionalized spacer couplings may be rapidly and cheaply produced by screw machinery from continuous tubular stock. \Nhen assembled, the respective tips of the internal tie members [8 and [9 also tightly abut end to end as indicated. An inherently strong sectionalized post is thereby built up that is well adapted to rigidly mount my plates in a laterally fixed spacing and in which the several interlocked components are unlikely to become unscrewed in normal use. My side plates are kept sufiiciently thick to afford an inherently stiff bridge medium between their spaced supporting posts.

The perforated finger pieces or heads of a plurality of Yale keys such as 23, 23, 23 are intended to be strung upon the assembled primary post I6, as shown in Figs. 1 and 2. Since certain of such key head perforations are likely to be somewhat smaller than the outside diameter of my axially aligned tubular sections may be kept to a corresponding size and still provide for adequate plate securement. The sectionalized post length L is preferably such as to correspond to the room required for one or two additional keys. For instance, in Fig. 6 the overall plate spacing is intended for a three or six key holder dependent upon the key head thickness, although all such demountable couplings need not be held to one and the same dimension. It will be obvious that by taking out or adding a post section, the key capacity of my holder plates will be crrespondingly altered in stepwise fashion. The solving of this requirement in a neat and commercially acceptable manner, has heretofore presented an inherently diificult problem.

My laterally dished spacer washer 20 is intended to be interposed between each of the assembled keys and also between the respective holder plates as in Fig. 1. This circular washer may be stamped up out of thin spring brass or the like sheet metal of about 0.010 thickness into the truncated conical profile shown in Fig. but without exerting an undue thrust upon the frictionally retained keys. The apertured crown thereof is invertedly indented to provide for a outstanding annular thrust nose component 2| disposed intermediate the washer perimeter and its central post receiving aperture 22 to afford a nose disposition that shall be materially larger in size than the diameter of the key head perforation so as to maintain the mounted keys in parallelism while being relatively shifted in the Fig. 1 manner. When said resilient agency is inter posed, the next adjacent keys respectively bear against said nose and its washer perimeter. The overall post length is so adjusted that when a pair of fastening screws I9 are tightly drawn into place, they serve to properly spring the washers laterally to a limited extent and thereby provide for the desired frictional key action.

The notch M is so located that the thumb is enabled to simultaneously actuate all the key heads and shift their shanks out of nested position, whereupon some one key such as 23 may be selectively extended into its Fig. l operative position, the remaining keys then being returned into their original housed position so as to afford a grip for conveniently manipulating such selected key. The same notch allows a reverse manipulation of the key heads to throw all their shanks against the stop pin l6.

The use of said circumscribing nose located remote from the washer aperture, not only accurately guides the shiftable keys without interference, but also frictionally retains an extended key in substantial alignment with the longitudinal plate edge against inadvertent folding about the primary post IS.

The secondary post I6, serves as supplemental plate spacing means and also acts as a stop when the keys are folded within the plate housing confines. It will be observed that the squared ends of my posts abut the inner plate faces and are of such diametral size as to overlie the spanned plate apertures.

my holder, it is merely necessary to remove one of the primary post screws such as H! and then swing the loosened side plate edgewise about the secondary post into the oblique Fig. 4 position. The insertion of an additional key and washer would call for the use of an extra post section of which such spare parts are intended to be furnished as new holder equipment when sold to the trade.

In Fig. 7 there is illustrated a modified style of post section 25 of which one end is provided with a diametrically reduced size of teat 26 adapted to be permanently riveted over one side plate, as shown. The opposite post end may be tapped for the reception of the screw l9 when a single post section is resorted to, or a splicer stud I8 as in Fig. 6 when multiple sections are needed.

The foregoing disclosures will make evident the devising of a neat and compact key holder of the adjustable type that admirably lends itself to low cost fabrication and one that possesses long life under arduous service conditions. As will be understood by those skilled in this art, certain of my structural refinements may also find application to analogous purposes other than key holder needs, and that various structural changes in the details and disposition thereof may be resorted to in likewise carrying out my single illustrative embodiment, all without departing from the spirit and scope of the invention heretofore described and more particularly pointed out in the appended claims.
