Description

1 2765025

  The present invention relates to a compact disc / cassette storage unit, and more particularly to an assembly type compact disc / cassette storage unit which can be easily assembled and disassembled by the user. A plurality of such units can be stacked to hold multiple compact discs and cassettes. Compact discs and cassettes are the main media in the music market. Storage of compact discs and cassettes is problematic when the number becomes large. Existing devices for storing compact discs and cassettes are generally boxes or shelves which are fixed in shape. Therefore, the number of discs and cassettes is also fixed. It is therefore desirable to have a storage device with the capacity to

  storage can be easily increased as desired.

  A primary object of the present invention is to provide an assembly-type compact disc / cassette storage unit, in which a plurality of such units can be stacked to hold a larger number of compact discs and cassettes. In addition, the storage units are easy to assemble and disassemble by the user. These features and benefits and others

  will appear more clearly from the description

  following detailed and accompanying drawings, in which: - Figure 1 is an exploded perspective view of the present invention; - Figure 2 is a schematic perspective view in the assembled state of a stack of storage units according to the present invention; - Figure 3 is a top view in the assembled state of the present invention; - Figure 4 is a sectional view in the assembled state of the present invention; and

  - Figure 5 is a sectional view in the assembled state

  of the present invention taken from a different angle.

  As shown in the drawings, a storage shelf is formed of a plurality of CD / cassette storage units according to the present invention. Each storage unit comprises a shelf plate 1, four support rings, a plurality of assembly rings 3 and

ring caps 4.

  The shelf plate 1 is a structure similar to a sheet preferably made of transparent material such as acrylic, and has a dimension corresponding to that of a compact disc. The four corners thereof are respectively provided with plate holes 11 for the passage of the respective support rings 2. A flat washer 12 having a central through hole and passing through the

  plate hole 11 is provided on each plate hole 11.

  The flat washers 12 are provided with radial ribs to facilitate positioning of the support rings 2 on them. In addition, so that a compact disc placed on the shelf plate is appropriately positioned, two bars 13 are provided to extend from a lower side of the shelf plate 1 on one side, the distance between the bars 13 being less than the width of a compact disc. Simultaneously, on both sides of the shelf plate 1, near the flat washers 12, two projections 14 are also provided to extend downward from the plate. The distance between the projections 14 corresponds to the length of a cassette so as to guide the cassette into position when it is put in place. In addition, two legs 15 are arranged near the center of the shelf plate 1 to serve in

  as long as the stops are placed in the cassette.

  The support rings 2 each comprise a support seat 21, the center of which extends upward to form a support column 22 with an external diameter corresponding to the internal diameter of the plate hole 11 of

3 2765025

  so that it can be passed through the plate hole 11.

  The interior of the support seat 21 is formed with a blind support hole 23 (not shown because of the projection angle), the internal diameter of this also corresponds to the external diameter of the support column 22 in assembly purposes. The height of the support seat 21 is slightly greater than the thickness of a compact disc. The assembly rings 3 each have a dimension corresponding to the difference in height between a cassette and a compact disc. Each assembly ring 3 is provided centrally with an assembly hole 31 corresponding to the plate hole 11. The purpose of providing the assembly rings 3 is to raise the height of the

  storage available when placing a cassette.

  The ring caps 4 are of colonial or cylindrical structure, each being provided centrally with a blind cap hole 41 (not shown because of the projection angle). The purpose of providing the ring caps 4 is to cover the support columns 22 projecting from the uppermost unit so

  to improve the visual appearance of the present invention.

  With reference to the drawings, during assembly, the support columns 22 of the support rings 2 are passed through the corresponding plate holes 11 to define a space, the height of which can receive a compact disc A. When the compact disc A is positioned, the bars 13 serve as a support. Therefore, the disc

  compact A can be positively positioned without sliding.

  When it is desired to store a cassette B, the assembly rings 3 are fitted on the flat washers 12 of the plate holes 11 respectively, and the support rings 2 are placed on it. Cassette B is inserted from one side and guided between two projections 14 until it is stopped by the legs 15 and then

4 2765025

  positioned. Therefore, each space can accommodate two cassettes B. In order to allow good air ventilation in each unit of the present invention, the shelf plate 1 is formed with a plurality of vents or air slots. But as this is a technique well known in the state of

  technique, it will not be discussed in more detail below

  after. In view of the above, it can be appreciated that the storage units of the present invention can be stacked and extended in modular form. In addition, the assembly rings 3 can be selectively used to increase the height of the storage spaces for receiving compact discs or cassettes, which does not exist in the prior art. In particular, the present invention can be easily assembled and

  dismantled by the user without any tools.

  Although the present invention has been illustrated and described with reference to the preferred embodiment thereof, it should be understood that it is in no way limited to the details of this embodiment but that it is capable of numerous modifications in the

  within the scope of the appended claims.
