KEY-RETAINING AND SUPPORTING MEMBER Filed May 29, 1939 ff/MC Q GE'LLER INVENTOR ATT EY I Patented Apr. 16, 1940 UNITED TAT- s PATENT OFF-ICE KEY-RE' I AIN ING AND-SUPPORTING. MEMBER IsaacGeller, Portlanioreg. ApplicationMay 29, 1939, Serial No. 276,407 10 Claims. j ((11. 70- 458) Broadly} this invention relates to key-retain-' ing and supporting members which are removably or otherwise associated with metal plates secured to a flexible folder; and specifically, the

invention is directed to key retaining and supporting members which are capable of pivotal and swivel connection to key plates removable at will and providedwith means for not only performing this function but also the additional function of preventingthe accidental removal retaining and supporting members.

A key-retaining and supporting member emof keys once they have been strung on said keybodying the structural features of improvement:

defined by my invention is adapted for use in key cases which provide mountings or key plates possessing facilities for allowing'the removal or replacement of the key-retaining and supporting members, whenever desired. For example, the

key-retaining and supporting members embodying my invention may be used in association with mountings orkey plates possessing the'characteristics described and shown in United States Patent No. 2,145,477 granted to me January 31, 1939, or mountings or key plates as":1escribed and shown in my pending United States'application, Serial No. 233,020, filed October 3, 1938. It is, of course, possible to use the holders em-. bodying the invention with any other type'of mountings or key plates which are provided with properly'sized slots for'receiving the key-retain-1 ing and holding members and which permit their removal and replacement, when desired. One of the objects of the inventionis-to provide a key-retaining and supporting member adapted for use incOnjunction withakey case provided-with means for allowing'a swingable and swivel connection between the key-retaining and supporting member and the key case.

As a corollary to the above object, still another object of the invention is to provide a keyretaining and supporting member 'directedto.

such structural features "of "improvement as will permit it to be readilyremovedfrom the key case with which it is associated and yet insure against the accidental removal of the key therefrom.

Another'importantobiect of the invention is to provide a key-retaining and supporting mem-' her which; when once itis confined within the" key plates, positively prevents the key supported thereby from being'tremoved therefrom without first removing said member from the keyplates. Still another objectof the invention is to provide an article of manufacture of retaining and ple to operate."

characteristics of akey ring and'thus may be used independently from the key case for the purpose of supporting and retaining more than one key. v

Still another object of the invention is to provide a key-retaining and supporting member which is, capable of retaining one or more keys anclwhich permitsthe removal of one ormore of saidkeys from said member with a minimum of-manual manipulation of the locking means provided therefor.

A further object of the .invention'is to provide a key-supporting and retaining member which is neat, strong anddurable, and inexpensive to manufacture and which is comparatively simparent from the, description which follows in which reference to the features of novelty inherent in theinvention with relation to their utility will be made-and which must be read in I I I connection with the "accompanying drawing showinga preferred form and several modified forms of the key-retaining and supporting member embodying'the principles" of my invention;

For purposes of clarityand brevity the key-retaining and supporting members will be hereafter referred to as key hangers; and in the drawing, parts having the same structural characteristics will be identified by the same reference characters.

The key hanger is made of two separate members, namely, a pivotal and swivel anchor and guard and a key-retaining loop secured to said anchor and guard. In the drawing the anchor and guard is designated, generally by reference character A and the key-retaining loop by-reference character B. To assist in pointing out the utility and functions of the invention and to point out its relation to a key case, there is shown in Figures 1 and '2 a key plate assembly, generally designated by reference character C and embodying the principles of my invention disclosed in my pending United States application Serial No. 233,020, filed October 3, 1938. Described generally, the key plate assembly C consists of a top plate I and a bottom plate 2 which are joined together by arcuately shaped end members 3 and 4. Plate I is provided with a wall 5 extending upwardly at right angles thereto which has a number of cutouts 6 therein. An arcuately shaped member -'I, having a pluralityv of spaced fingers 8 formed therein also arcuate in contour, is revolvably confined within the area circumscribed by the arcuately shaped end members 3 and 4 and wall 5 so that the spaces formed between the fingers, as shown at 8, coincide with the cutouts 6 in wall 5 and form curved slots into which a portion of the anchor and guard member A fits as will shortly be pointed out. An arm I!) is formed at one end of member I which, when locked against plate I, as shown in Figure 1,

prevents the'exposure of the ends of fingers 8 and consequently maintains the open ends of slots 9 covered. Key plate C may be attached in any desirable manner to a flexible leather or fabric cover II, a fragment of which is shown in Figure 2. The position assumed by the key hangers when confined within the slots 9 of the key plate C is best shown in Figure 2.

Other key-hanger supporting means may be provided for obtaining the same result. Consequently, the invention is not limited to a key plate such as described, but may be employed in any other type of key plate which will permit the removal of the key hanger assemblies hereinafter to be described in detail.

The key hanger embodying the preferred form of the invention has its anchor and guard member A formed of a shank or cylindrical bar I2. A bead or spherical head I3 is formed at or is secured to one end of the bar and another bead or spherical head i4 is formed at or is secured to the other end of the bar. The anchor and guard A thus formed suggests the shape of the well-known gymnastic dumb-bell. However, spherical head I3 is smaller than spherical head I4 and the function and utility of each is different as will shortly-appear. While in the drawing there is shown a spherical head I3, it is possible to employ a cylindrical flat top member to perform the same function;

The key-retaining loop member B is made of a single piece of metal, flat, circular or semicircular in cross section, bent to form an elongatedloop vwhich is bounded by two sides or legs I5 and I6 converging toward each other to form arestricted passage through which a key must pass and which merge to form a curved bottom I1. While the drawing shows the loop B formed into a tear drop shape, it may be stirrup shaped or formed into any shape which fashion or the whim of the manufacturer may dictate without any loss of utility. The metal employed possesses springlike qualities so that the legs are yieldingly urged at all times toward each other and require some force to pull them apart in order to permit passage Of a key therebetween as shown in Figure 5.

An eyelet i8 is formed at substantially right angles to and at the terminus of leg I5, as shown at I9, and an eyelet 2B is formed at substantially right angles to and at the terminus of leg I6, as shown at 2|, by bending the terminals of the respective legs into closed loops. These eyelets are normally maintained in direct parallel alignment with each other so that the eyelet I8 and eyelet 20 are parallel to each other but in different planes and are in substantial registry but spaced apart a distance slightly greater than the thickness of the average key head to give clearance thereto. The relationship of the eyeletsto each other is best shown in Figure 6.

The anchor and guard member A'is slidably positioned and rotatably secured to the key-retaining loop member B. This is accomplished by making the diameter of eyelet 20 slightly greater than the diameter of the bar I2 but slightly less than the diameter of spherical heads I3 and I4. On the other hand, the diameter. of eyelet- I8 is not only greater than thediameter of bar I2, but also greater than the diameter of spherical head I4, therefore permitting the spherical head I4 and bar to enter and pass beyond the eyelet I8 while the eyelet 20 restricts the movement of the anchor and guard member A to the length of thebar. The length of the bar I2 is such that when inserted into the eyelet I8 the spherical head I 4 extends only a short distance beyond the eyelet.

It at once becomes obvious that, unless the spherical head I4 is supported by some means in the positions shown in Figures 3, 4, '7 and 8, asby a key plate assembly in the manner shown in Figure 2, it will be forced by gravity to assume the position shown in Figure 5. In constructing the key hanger assembly embodying the invention, the spherical head I4 will be made so that its diameter will be greater than the width of the slots provided in the key plate C such as slots 9,

not only is it possible to atomic and the bar l2 will be made so that its thickness" the key assumes the position shown'in, Figure 5.

When'the key is thus strung and the leg 16 is allowed to assume the position shown in Figures 3" and 4, not only does the normal urge'of' the legs toward each other prevent the key from being accidentally removed from the loop memher 3, but'the position oi eyelet 211 is an added barricade to such removal." Furthermore, once the bar I2 is inserted into' eyelet l8, a'positive guard against removal is provided.

By constructing the anchor and guard A as described, it will be possible for the key hanger assembly to hang loosely ma key case with the spherical head positioned in slot 9 to form a ball and socket joint for unrestricted manipulation of the key hung thereon, and for the spherical head M to revolve on its own axis while the key-retaining loop B may rotate at will with bar 12 as its axis.

Such construction provides extreme freedom of movement for each key hanger without'any loss of security for the keys themselves. -When a key is selected it is swung outwardly on its pivotal connection with the key plate and the key may be revolved in a look without any manipulation of the case. It should be noted that pivot and revolve the assembly with respect to the case,but also that the loop is capable of turning. Thus a very flexible working connection is provided for the loop and also for the key on the loop, affording convenience and natural use and manipulation of thekey in practically any direction and manner desired. In addition to the above, the removal of the hanger from its respective slot 9 does not lessen the security of the key which is retained on the key-supporting loop B.

By a slight twist of the eyelet so that it will not contact the leg IE, it is possible to place leg IS in direct contact with leg l5 as shown at 22 in Figure '7 thereby increasing the degree of convergency of the legs. Except for this slight rearrangement of the position of eyelet 20 without, of course, changing its alignment and registry with eyelet IS, the key hanger shown in Figure '7 possesses the same structural characteristics and functions in substantially the same manner as the key hangersshown in Figures 1 to 6 inclusive.

Should it be found expedient to employ a fiat springlike metal as illustrated'in Figure 8 for the manufacture of key hangers embodying the invention. this metal could be formed to assume the same general contours of the key-retaining loop B. However, its legs 23 and 24 are slightly enlarged at their extremities and are bent at right angles to form a pair of ears 25 and 26 respectively, spaced apart but in parallel relation to each other. An opening 2! is formed in ear 25 and an opening 28 is formed in ear 26. While these openings are in direct alignment with each other. they possess different diameters, and their respective diameters conform substantially to the diameters of eyelets l8 and 2!! of the key hangers shown in Figures 1 to '7 inclusive. The anchor and guard member A is similarly secured I8 is inserted into'the opening in the tothe modified key-supporting-loop 3 shown in Figure 8 andv operates in a manner in every respect identical-to its operation when secured to thekey supporting loop B shown in Figures 1 to I inclusive- The invention has bee'n'described in connection with a number of illustrative embodiments possessing definite form. and referring to definite' material's, 'methods of preparation thereof and use. To these details of disclosure, the invention, of, course, is not limited, since what is claimed as new and whatis desired to be secured by Letters Patent is set forth in the appended claims.
