DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing articles from dropping from a storage shelf, and more particularly to an article such as a reagent bottle placed on a shelf plate of a reagent shelf being shaken by an earthquake or accidentally hitting a hand. The present invention relates to a device for preventing articles from dropping on a storage shelf for preventing the articles from falling due to being dropped or misheld.

[0002]

2. Description of the Related Art In a conventional device for preventing falling of articles on a storage shelf, a fall prevention bar is provided between opposing surfaces of a column supporting a shelf, and an upper surface of the shelf is mounted in units of a distance between the columns. It was divided by a fall prevention bar.

[0003] For example, as disclosed in Japanese Utility Model Publication No. 58-47898, a groove having a narrow entrance portion and a wide depth is formed in a bracket having a protruding key-like leg fitted into a locking hole of a column. A shelf frame combining a rod and a rod holder having a connecting rod at its head and having a tubular body at its tail, which is drilled on the side and can be fitted and locked in the groove, is described.

However, when the drop prevention bar or the rod described in the official gazette is laid laterally above the shelf board by using the locking hole of the column, there is little danger of falling articles, so that it is divided by the partition. There is a drawback in that the area to be covered is the entire surface of the shelf, and the fall prevention bar also exists in unnecessary parts, so that a part of the shelf cannot be used as a storage space for other uses.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is intended to solve the problem by placing a fall prevention bar laterally above the above-mentioned shelf board and removing the article placed on the shelf board of the storage shelf. A storage shelf that can prevent falling and has a degree of freedom in the mounting position and combination of the fall prevention bar, and can create an area defined by the fall prevention bar only in the necessary part of the upper surface of the shelf board. An object of the present invention is to provide an article fall prevention device.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims at preventing the articles placed on the shelves of the storage shelves from dropping, so that the upper surface of the shelves or the columns supporting the shelves are supported. A plurality of block-shaped support members are detachably attached to the inner surface, and the end portion or intermediate portion of the drop prevention bar is held on the support device, and the article drop prevention device of the storage shelf horizontally disposed above the shelf plate. Wherein the supporter is provided with means for attaching to a shelf or a support, and mounting means for attaching the support by the attachment to the shelf or support are provided at a plurality of locations, and a fall prevention bar is fitted. An article drop prevention device for a storage shelf in which the first engaging portion and the second engaging portion are formed to be orthogonal to each other is configured.

Here, the first engaging portion is preferably a concave groove having one end closed, and the second engaging portion is preferably a concave groove having one end closed or both ends opened. It is more preferable that a partition member having a thickness sufficiently smaller than the length of the concave groove is detachably mounted in the concave groove of the second engaging portion so that the concave groove can be closed. It is practically convenient to make the part detachable from the support body.
