1 MAGNETIC RECEPTACLE FOR KEYS AND THE LIKE BACKGROUND OF THE INVENTION 1. Field of the, Invention This invention relates to receptacles for keys and the like and, more particularly, to key cases in which access to a desired key can be obtained without opening the key case.

springs or spring-type mechanisms, which are subjecttofailure and must be treated with an amount of care not often possible in their practical use. Additionally, these mechanisms, because of their complexity, are relatively expensive. Further, the complexities of the prior art devices often result in malfunctioning the devices so that the keys cannot be extracted or are jammed in the down position, rendering the case inoperative, or at least inconvenient to carry.

SUMMARY OF THE INVENTION To overcome the problems set forth in the prior art,

the present invention provides a receptacle for keys and the like having a body of magnetically susceptible material in the case, with guide paths through the walls of the case adjacent the magnetically susceptible material. Keys are connected to magnetic means held in place by their attraction of the magnetically susceptible material. Positioning means are connected to each magnetic means and extend through each of the guide paths to connect with protrusions on the exterior surface of the key receptacle, so that a key can be extraced from or withdrawn into the receptacle by adjusting the positioning means on the outside of the receptacle.

Accordingly, it is an object of the present invention to provide a simplified apparatus for positioning an individual item from a receptacle without opening the receptacle.

Another object of the present invention is to provide a case for keys and the like which affords access to a single item within the case without opening the case, and which is reliable in operation.

It is a further object of the present invention to provide a case for keys and the like which allows access to a single item within the case without opening the case, and which is inexpensive to fabricate.

Yet another object of the present invention is to provide a case for keys and the like which allows access to a single item within the case without opening the case, in which the mechanism for positioning the item adds strength to the structure of the case.

It is still another object of the present invention to provide a case for keys and the like which allows access to a single item within the case without opening the case, and which does not have any delicate moving parts.

A further object of the present invention is to provide a case for keys and the like which allows access to 2 a single item within the case without opening the case, and which operates by the laws of magnetism.

Yet another object of the present invention is to provide a case for keys and the like which allows access to a single item within the case without opening the case, and which can be easily operated with one hand.

Still a further object of the present invention is to provide a case for keys and the like which allows access to a single item within the case without opening the case, and which is resistant to jamming.

Another object of the present invention is to provide a case for keys and the like which allows access to a single'item within the case without opening the case, and which is relatively small in size.

Other objects and advantages will be apparent from the following description of an embodiment of the invention and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevation of a key case built in accordance with the teachings of the present invention.

FIG. 2 is a side elevation of FIG. 1.

FIG. 3 is a top elevation of FIG. 1.

FIG. 4 is a partial view, taken along lines 4-4 of FIG. 3. FIG. 5 is a rear view of the key case shown in FIG. 1, with the case in the open position.

FIG. 6 is a perspective view from the front of the key case shown-in FIG. 1.

FIG. 7 is a view taken along lines 7-7 of FIG. 6.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIGS. 1 through 7 show a key case, generally in dicated'at 10 having a front panel 12, and overlapping

side panels

14 and 16, adapted to form a closed container with snap fastening means 18 and 20.

As shown in FIG. 3, inner flat 16 has a separating section 22 adapted to coact with the front panel section 12 when the case isclosed, to divide the case into

separate compartments

24 and 26. The front panel of the case includes a section of magnetically susceptible material 28 (in other words, material which is capable of being attracted by a magnet), which is fixed to the remaining portion of the front panel by any convenient method, such as gluing, stapling, stitching, etc. The magnetically susceptible material can be any material capable of being attracted by a magnet as, for example, a sheet of iron or any of the magnetically attractive plastics.

Two guide channels or

slits

30 and 32 are formed in the panel of magnetically susceptible material and communicate the exterior of the case with the interior of the case.

Pins

34 and 36 extend through

slits

30 and 32 respectively to connect with

magnets

38 and 40 respectively forming protrusions on the outside of the case, and with mounting means 42 and 44 on the inside of the case.

Keys

50 and 52 are attached to

key rings

46 and 48 which are connected to

mounting means

42 and 44, connected, in turn, to

magnets

38 and 40.

The magnets, in the shape of buttons, are held in position on the panel of magnetically susceptible material by the attraction of the two materials. When it shown in FIGS. 1 and 3, the magnetic button 38 is simply pushed along slit 30 in the panel of magnetically susceptible material it until it reaches the bottom of the slit, in which position the key is fully exposed and'accessible. To return the key to the inside of the case after it has been used, the magnet is merely pushed to the upper end of the slit, as, for example, magent 40 shown in the raised position in FIGS. land 6.

Since most house keys are of brass or aluminum, they will not be afiected by the presence of the magents.

It should be pointed out that although the embodiment described in the present application sets forth a construction in which the magents ride directly on the magnetically susceptible material, this need not be the case. For example, a layer of magnetically transparent material can be interposed between the magents and the magnetically susceptible material without substantially affecting the performance of the device. The attraction between the magnet and the magnetically susceptible material would still be present and the magnet would just be drawn against the magnetically transparent material instead of directly against the magnetically susceptible material.

It should also be pointed out that the magnets need not be placed on the outside of the key case. Instead,

the magnets could be located within the case and protrusions could be fastened to the pins extending through the slits to position the magnets from the outside ofthe case through the slits in the case.

It should also be noted that the magnetically susceptible material need not extend the entire length of the key case, nor be one continuous piece, for all applications of the device. For example, if it is only desired to have keys held in the case held in the uppermost position with no intermediate positions, then the magnetically susceptible material need only be placed near the upper portion of the case, so as to hold the mounting means in the upper position. Further, several individual strips of magnetically susceptible material could be positioned to form the slits.

Additionally, keys can be positioned in the case so that they can be extracted by moving the positioning means to opposite ends of a single slit. For example, if the keys were placed in proper position with relation to each other, moving the positioning means to one end of the slit would project one key from the case while moving the positioning means to the opposide end of the slit would project a different key from the other end of the case. In such a construction, positioning of the positioning means in the middle position would fix both keys within the case.

It should be pointed out that the simplicity of con-' struction and operation of the device insures troublefree performance, and allows the device to be operated with one hand.

It will be understood that various changes in the details, materials and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by those skilled in the art within the principle and scope of th invention as expressed in the appended claims.
