ABSTRACT:
BACKGROUND OF THE INVENTION
The invention concerns a receptacle for assembling and storing records, particularly compact disks, as well as audio and/or video cassettes which can be expanded by mounting or adding on additional elements (boxes).
In addition to commercially available receptacles for records and/or cassettes which are constructed from the start only for a fixed number of records or cassettes and cannot be expanded, receptacles are also known which are capable of expansion. In the latter, a plurality of elements are placed either on top of or next to one another. However, there is no secure connection of these elements. At best, there are positioning pins and positioning bore holes or fastening strips in the region where one element is placed on top of another. The disadvantage of these receptacles therefore consists in the absence of a fixed and permanent connection. In particular, one element added on top of another can be easily upset and fall over. This risk is posed in particular when an element placed on top of another is top-heavy due to only partial filling with records, etc. and when the user removes the sound recording.
SUMMARY OF THE INVENTION
The present invention has the object of providing a receptacle of the type indicated above in which a fixed and permanent, but detachable, connection of the mounted or added on elements is effected, in which the useful space of the receptacle and elements is not limited or obstructed by projecting connection parts, and in which the connection can be effected effortlessly, also by nontechnical persons.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a mounting or add-on receptacle for records and cassettes including two or more elements which are set one on top of the other or added on to one another and have receiving devices for the records and cassettes to be inserted, wherein in accordance with the present invention the elements are securely but detachably connected in the region of the cover end base by one or more bayonet screws, the bayonet screw has a flat hat and at its opposite end at least one cam-like bayonet shoulder at the screw neck and is inserted in overlapping bore holes of the base and of the cover of the elements and is flush with the surfaces of the base and cover on the inside of the elements without projecting out, the bore hole in the base on the inside of the elements which reaches the height/thickness of the screw head has the diameter of the latter and tapers in the portion of the base adjoining the latter to the maximum diameter of the screw neck, including the bayonet shoulders, while the bore hole in the cover on the inside of the element has the diameter of the screw neck of the bayonet screw, including the bayonet shoulders, and cam-like projections project into the latter in the region directed toward the outside of the elements, while the bayonet shoulders of the bayonet screw engage under the cam-like projections.
When the mounting receptacle for records or cassettes is designed in accordance with the present invention, it eliminates the disadvantages of the prior art and provides for the above identified highly advantageous results.
In accordance with another feature of the present invention the two elements have a plurality of connections by means of the bayonet screws, the latter being inserted reciprocally into the base from inside of the elements on the one hand and into the cover from the inside of the elements on the other hand, so that additional bore holes are arranged in the cover which are shaped like the bore holes, and bore holes corresponding to the first mentioned bore holes are arranged in the base.
In accordance with still another feature of the present invention, the receptacle can have two or more laterally adjoining elements which are connected with the adjacent outer walls of the elements by one or more bayonet screws via bore holes.
Finally, the bayonet screw and the screw head can have a widened slot for inserting a coin.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
