Description

The present invention relates to a rack for accommodating articles, and more particularly to a rack on which articles can be placed on the upper surface.

In order to efficiently store goods in the warehouse, a rack as described in Patent Document 1 is used. This rack is formed in a substantially cubic shape surrounded by columns, and a plurality of square timbers are connected in a grid pattern on the upper surface to form a mounting surface. As a result, the article can be stored inside the rack, and the article can be placed on the mounting surface which is the upper surface of the rack.

Further, this rack is configured so that other racks can be stacked. Therefore, the upper surface (mounting surface) of the rack located on the lower side is located at the bottom inside the rack located on the upper side, and articles can be stored in such a place, and the upper surface of the rack located on the upper side is further located. Articles can also be placed on the (placement surface). This is intended to improve storage efficiency.

Japanese Unexamined Patent Publication No. 2010-47375

However, in the rack described in Patent Document 1, when an article is placed on the mounting surface which is the upper surface, there arises a problem that the placement state of the article is not stable. For example, when the outer shape of the article facing the mounting surface is smaller than the outer circumference of the mounting surface, the outer peripheral portion of the article is not supported without contacting the member forming the mounting surface of the rack. turn into. In particular, when the outer shape of the article facing the mounting surface is rectangular, the corner portion of the article is not supported by any member of the mounting surface and is in a state of floating in the air. Then, there arises a problem that the mounting state of the article on the mounting surface of the rack becomes unstable.

On the other hand, in order to stably support the article on the mounting surface, it is conceivable to arrange a large number of square timbers on the mounting surface at narrow intervals to reduce the grid-like mesh size. However, increasing the number of square timbers on the mounting surface of the rack causes problems such as complication of the rack structure and an increase in the weight and cost of the rack itself.

Therefore, an object of the present invention is to provide a rack capable of solving the above-mentioned problem that the state of placing articles on the upper surface of the rack becomes unstable.
