KEY IDENTIFICATION AND FILING MEANS Filed Feb. 25, 1957 lffOf/VEV nit-ed States Patent 2,932,101 KEY IDENTIFICATION AND FILING MEANS Scipione Roger Manzardo, Lucerne, Switzerland Application February 25, 1957, Serial No. 642,232 Claims priority, application Switzerland May 10, 1956 9 Claims. c1. 40-330 This invention relates to a key identification and receiving means to be applied to'the handle of a key or similar object. In 'order easily to distinguishseveral keys from each other which are kept on a ring, in a case, on a key rack or otherwise, the keys heretofore have been provided with tags which are movably connected to the key handle by means of a hook, a chain or other intermediate piece. These known identification means suffer from the disadvantage that they are often larger than the respective keys themselves, that they are liable to interfere'with each other or other objects and can then not vbe easily separated, and that on racks with several rows of' keys, they often hang down over the next underlying row, covering those keys or preventing their separation or attachment. For keys which are to be carried in pocket cases the known'tags are of course entirely unsuitable. I

With the identification means according to'the present invention all aforementioned shortcomings are obviated.

The primary object of the invention is to provide a cover for a key which will facilitate its identification in an assembly and the insertion and removal of the key therefrom, by means of projections extending from the rim of the cover and integral therewith.

Another object of the invention is to provide such a .cover of amaterial with properties of resilience permitting keys with various handle sizes to be easily fitted with the :same size cap, for instance, by a snap-on action, by stretching the cover over the handle of; the key.

Still another object of the invention is means for identt'ification of each key by including in the cover above described an outer pocket parallel to the rim of the cover for insertion of visual identification, or key indexing means- Yet another object of'the invention is'to provide the covers above described in a plurality of colors also for reference purposes.

Another object of the invention is a method of providing a plurality of keys in an assembly with a kit of covers, each having a rim projection parallel with the axis of the key, equipped with means for attaching it into an assembly provided with cooperating means, and each cover having a rim projection or projections spaced radially differently from those of the other covers for reference purposes, in order to provide variably headed keys.

Other objects of the invention will become apparent from the following description and claims taken in conjunction with the accompanying drawings wherein:

Fig. 1 is the face view of a form of the invention showing a key receiving means with an identification tag frame;

Fig. 2 shows a section on the line VI-VI of Fig. 1;

Fig. 3 shows the cap according to Fig. 1, arranged on the handle of a key;

Fig. 4 shows a section similar to that of Fig. 2, on a larger scale with a designation ticket and protective cover applied to the cap;

Fig. 5 shows a key receiving means similar to those of Fig. 1 with a key identification projection.

. 2 V Fig. 6 represents a designation plate and its protective cover of transparent material.

The key receiving and identification means shown in the several figures comprises a snap-on cap orcover envelope 20 which is made of flexible stretchable material,- such as natural or synthetic rubber or rubber-like synthetic substance. In accordance with the invention the elastomeric properties of the cap are such that it will be stretched to approximately double its size, to permit the use of the same standard-sized cap as a cover for key handles differing in size. Thecap 20 includes 'two parallel flat sides orwall disks 21 which are connected to each other along their periphery so as to leave a bottom opening 22 for insertion of the handle part of a key. Alateral projection 30 is provided on the rim of the cover and extends axially in direction opposite to that of a key inserted in the cover. The sides preferably have the outline of circular surfaces cut along a chord. Theprojection 30 is perforated to form ahole 31. The edge of the insertion opening 22. is strengthened by abead 24 which extends round it. The edge of thehole 31 is also beaded. The external side of onewall'disk 21 preferably is provided with a mark such as a numeral, lettering, or symbols such as triangles etc. This mark is embossed, but could also berecessed or printed on the cap. The same mark could be applied to the front and to the back of the cap. I

The described identification means is stretched over the handle of akey 27, as shown in Figs. 3 and 5. To this effect the handle of the key 217 is pushed through the insertion opening 22 of thecap 20. It is thus possible to have a chain etc. threaded through thehole 31 or to hang the identification cap up with thekey 27 inserted therein.

The numeral on thecap 20 permits easily distinguishing thekey 27 from similar keys likewise provided with such identification means, it being of course understood that each of the identification means bears a different numeral.

" In order to facilitate the distinction of different keys with similar identification means, the latter preferably are made of contrasting colors, the paint being embedded in the material of the cap.

The marks or lettering may be provided with a color luminescent in thedark, or only with a color to easily distinguish the keys from each other by night. As analternative external areas of thecap 20 are provided with a coating luminescent in the dark or the whole identification means consist of a material luminescent by night.

Thisprojection 30 projects from the rim of the cap in the axis of the key and consists of the same material as thecap 20 and permits hanging up the key cover with the key therein. A head 3-2 extends round the edge of thehole 31.

One wall disk orface side 21 preferably has means to hold exchangeable designation plate and has to that effect, at its outside, aframe 35 formed by embossed ribs. Moreover, theface side 21 possesses twopockets 34 laterally adjoining the grooves and into which the ends of the strip-like designation plate 33 may be inserted.

According to Fig. 6, there is also provided aprotective cover 36 made of transparent material into which thedesignation strip 33 can be inserted. Withstrip 33 andcover 36 applied to thecap 20, the cover lies within theframe 35 so thatstrip 33 andcover 36 are protected. Fig. 3 shows a front view of thecap 20 provided with adesignation strip 33 andprotective cover 36 as fitted to the handle of akey 37. Obviously, thedesignation strip 33 may be changed as required and be lettered by the user of the identification means himself.

' 2,932,107 Patented 'Ap'r. I 2-, '1960 Fig. illustrates identification means according to the invention, in which thecap 20 is provided on jtsperiphery with at least one lateral cam-like projection 85 integral with thecap 20. Said at least oneprojection 85 serves as a feeder for key recognition for instance, by feeling with one finger, to make it possible to recognize by touchthe different keys. One or more than onelateral projections 85 may be cut on the cover at different points, in order to obtain an identification means for a plurality.

of keys. In this way a plurality of differently spaced, feelable signs are available for key identification.

A modification shown in Figure 5 has asuspension lobe 30, on which there is provided a cam-like projection 85 for key identification by touch.

An essential advantage of the invention resides in the fact that the identification means are well connected to their keys, require little space and do not dangle down beside the keys when hung up. The keys provided with the disclosed identification means are handler than keys with tags made in several parts and tag-holders of the design hitherto used.

It is intended that the present specification covers all changes and modifications of the embodiments shown and combinations thereof, which do not depart from the spirittand scope of the invention as claimed.
