4 Claims. (Cl. 211-13 This invention relates to devices for storing small articles, and more particularly to compartmented receptacles wherein a plurality of small articles may be separately stored in readiness for immediate and i11- dependent withdrawal and use. An example of such a device is a rack or board adapted to serve as a repository for a plurality of room keys, as in a hotel, or motel,

small articles, in spaced arrangement on the board, yet

readily detachable therefrom, and wherein the keys or other articles are secured against accidental detachment and loss. In connection with the operation of a used car lot, for example, it is the practice to keep the keys for the various cars on a board or rack in the sales ofiice. The cars on such a lot are customarily unlocked during the day, so that prospective customers may inspect them, and locked at the close of business, to prevent damage or loss during the night. In conducting such operations, it is usual for the operator of the business, or one of his employees, to take the rack of keys and make the rounds of all of the cars, unlockingor locking each as he comes to it. When the rack is provided with hooks or nails to retain the keys, as is frequently the case, the keys may easily be dislodged or lost while the rack is being carried about the lot, and a better arrangement is desirable.

An object of the present invention is the provision of a readily portable rack or board for receiving and retaining a plurality of'keys or other small articles, which may be carried about, may be tilted or even inverted, and otherwise handled in the most convenient manner, without risk of losing the keys or other articles which are attached to the board.

More specifically, the present invention has for its object the provision of a device such as described in the preceding paragraph, comprising a sheet-like member of rigid, nonmagnetic material provided with a plurality of spaced apertures extending therethrough, permanent magnet means associated with the respective apertures, and magnetic armature means associated with said apertures, one of said means extending through said associated aperture and into contact with the other said means and being formed to provide means for attaching a small article thereto.

Another object is the provision of a board such as described in the previous paragraph wherein the permanent magnet means comprises a plurality of separate magnets positioned one opposite each said aperture, said magnetic armature means comprising a plurality of plugtates Patent Q ice like elements of ferrous material each of a size and shape to be received in one of said apertures.

Another object-is the provision of a board of the character described, in which the permanent magnet means and armature means are reversed in position, the armature material being positioned behind the aperfiired sheet-like member, and the magnet means comprising a plurality of individual permanent magnets eachof a size and shape to be received in one of the apertures, and provided with means for attaching a small article thereto. v a

Other and further objects, features and advantages will be apparent from the description which follows, read in connection with the accompanying drawings in which:

In order to facilitate an understanding of the invention, reference is made to the embodimentsthereof sh'dwn in the accompanying drawings and detailed descriptive language is employed. It will nevertheless be under stood that no limitation of the invention is thereby iiitended and that various changes and alterations are cdiitemplated such as would ordinarily occur to one skilled in the art to which the invention relates. I

Referring to Figures 1-3, the embodiment there illustrated comprises a rigid sheet-like member 10 of any suitable weather-resistant and preferably, though not necessarily, non-magnetic material, for example aluminum, fiberboard or the like, provided with a spaced series of apertures 11 extending therethrough from front to back, and a second sheet-like member 12 of similar material, though unapertured, in spaced relation to the member 10. Between themembers 10 and 12 therea re ositioned, one in registry with each aperture 11', a plurality ofmagnet retainers 13 of suitable light-weight and preferably non-magnetic material, for example, molded plastic, wood, etc. The retainers are cenrentd or otherwise secured to the member 10, and serve to preserve the illustrated spacing between themembers 10 and 12 Eachretainer 13 is formed with a bore portion corresponding in size and shape to theapertufe 11 with which it is associated, and an enlargedbor'e portion fS of a size and shape to receive and retain" a permanent magnet 16 (Figures 2 and 3-). Themagnet retainers 13 may be made in two pieces to permit insertion of themagnet 16, the said two pieces being then secured together; or, in the case of molded magnet retainers, themagnet 16 may be molded in place as shown.

Eachmagnet 16 is formed with a slot '17 extending across one face thereof, and is magnetized in such manner that the material on opposite sides of theslot 17 constitute north and south poles, respectively. Themagnets 16 are permanent in nature, being made of any suitable magnetic material of high retentivity. The assemblage comprising themembers 10 and 12,magnet retainers 13 andmagnets 16, is held together by aborder frame 18 which surrounds and embraces the peripheral edges of themembers 10 and 12, theframe 18 being formed of any suitable material, for example aluminum channels secured together at their abutting ends in any conventional manner. Preferably, theframe 18 is provided with ahandle 19 for ready portability and, if detures, said magnetic armature means comprising a plurality of plug-like elements of ferrous material, each of a size and shape to be received in one of said apertures, one of said means being removably supported in one of said apertures by engagement with the material surrounding same, and extending through said associated itures 11,bores 14, andelements 20 are'cylindrical, and

"this is thought to be the most useful form, but obviously other shapes may be employed, so long as theelement 20 is shaped and sized to have a close fit Within the apertures 11 and bores 14. Eachelement 20 is provided with means for attaching a small article to be stored, and in the illustrated embodiment such means comprises "anaperture 21 through which may be passed the chain 122 of a conventional key retainer, which may also in- "clude atag portion 23 carrying identifying indicia. Akey 24 .(Figure 1) is attached to thechain 22 below the tag23.

" By virtue of the magnetic attraction between themagnets 16 and thearmature elements 20, and also because of the mechanical support for theelement 20 provided by the walls of the aperture 11 and bore 14, the armatures are securely retained within thebores 14 and in contact withmagnets 16. While they may be readily detached when needed, the board may be carried about, tilted, and even inverted, without accidental detachment :of thearmatures 20 and their respective burdens. By virtue of its construction as described, the board is quite light in weight, and may be made of a size to accommodate a large number of keys or other small articles, while retaining its feature of ready portability.

In the embodiment illustrated in Figures 4 and 5, a'sheet 25 of magnetic material, for example iron or mild 'steel, is sandwiched between sheet-like members 26 and and 27 of light weight non-magnetic material, themember 26 being apertured as seen at 28. Theaperture 28 is of a size and shape to receive a permanent magnet '29 which, as before, is provided with aslot 30 dividing its face into north and south poles. Themagnet 29 is provided with any suitable means, such as theeye 31 for receiving thechain 22 or other means of attachment of a key or other small article. In the illustrated embodiment, themagnet 29 is identical with themagnet 16 of Figures 2 and 3, and is provided with a frusto-conical extension 32 in which theeye 31 is embedded. Theextension 32 may be secured to themagnet 29 in any suitable fashion as by cementing, soldering, etc.
