[Industrial applications]

 TECHNICAL FIELD The present invention relates to a tray for a top plate arranged on the top of various storage shelves that can be easily assembled in an arbitrary number of stages.

[0002]

[Prior art]

 Usually, the storage shelves consist of four pillars made of angle material and a shelf board supported by these pillars. Then, the four corners of the shelf board are fitted to the angle portions of the support columns and fastened with fasteners such as bolts. In order to strengthen the connection between the support pillar and the shelf board, corner fittings may be interposed between the contact portions.

By the way, in the above-mentioned conventional storage shelves, fasteners such as bolts are used to support the shelves on the columns, and locking members such as corner fittings are used for the columns and the shelves. Must be intervened between them, which makes the assembly operation extremely troublesome. There is also a problem that the number of parts for assembly such as bolts and corner fittings is large, which increases the manufacturing cost. Further, since the shelf plate has a flat plate shape, articles to be stored can be placed, but in the case of granular substances or liquids, they cannot be stored on the shelf plate.

Above all, in the conventional storage shelves as described above, since the shelves are bolted to the columns, it is difficult to say that the appearance is beautiful, and it is practical, but it is used in the interior of the room. It was not something that could be applied.

Therefore, in order to solve the above-mentioned drawbacks of the conventional storage shelves, a storage shelf as illustrated in FIG. 4 can be considered. This storage shelf is formed by forming a unit shelf body 2a with a plurality of cylindrical unit columns 1 and a unit shelf 2 supported by the unit columns 1, and stacking the unit shelves 2a. . A fitting hole 11 is formed at the upper end of the unit column 1 and a fitting protrusion 12 is formed at the lower end. In addition, the unit shelf 2 is provided with a storage portion 21 which is depressed over the entire central portion, and is fitted into the fitting hole 11 of the unit column 1 at the lower end of each corner of the unit shelf 2 in the vertical direction. A fitting projection 32 is provided, and a fitting hole 31 into which the fitting projection of the unit column 1 is fitted is provided at the upper end. Then, the fitting holes 11 of one set of the unit columns (four) are fitted into the fitting protrusions 32 of the unit shelf 1 to form the unit shelf body 2a, and the plurality of sets of the unit shelf bodies 2a are joined together. A storage shelf having a plurality of stages is formed. A top tray 40 is arranged at the uppermost part of such a storage rack, and stored items can be placed also in this portion.

In the storage rack configured as described above, the storage rack R is formed only by fitting the unit support columns 1 and the unit racks 2 to each other without using a fastener for special connection. Since it is a simple one, the assembly operation is very simple, and anyone can easily make the storage rack R with the desired number of stages, and the unit shelf 2 can have various shapes such as plate shape and box shape. By doing so, the range of application of the storage rack R is remarkably wide. Therefore, for example, if a recessed storage portion 21 is provided in the unit shelf 2 and a through hole 22 is drilled in the bottom surface, Since 22 serves as a drainage hole, it becomes possible to fill the storage section 21 with sand and use the unit shelf 2 as a planter. If the unit shelf 2 is made of transparent synthetic resin, it is for ornamental use. It can be used as a fish tank This is convenient because the scope of application is always expanded.

[0007]

[Problems to be solved by the device]

 By the way, in the conventional storage rack R as described above, the top tray 40 provided at the uppermost stage does not have a shock absorbing action and breaks because the top surface thereof merely forms a flat surface. A soft and elastic sheet is usually used as a rug to protect an easy-to-use item.

However, since such a sheet 45a is simply placed on the top tray 40 in the related art, the sheet 45a often shifts on the top tray 40, and if the sheet 45a shifts, the placed sheet rolls over. In the worst case, it falls from the tray 40 for the top plate.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to mount a seat in a state where it is securely fixed at a predetermined position, and the seat is attached and detached. The purpose is to provide an easy tray for the top plate.

[0010]
