Description

  The present invention relates to an article display shelf installed for display of articles in a store or the like.

  Article display shelves for exhibiting articles such as products in stores are often used assembling-types composed of columns, legs, shelves, etc. so that they can be easily installed, moved, changed in display method, etc. .

  In such an article display shelf, support pillars extending upward are respectively erected on base legs that are installed in pairs on the floor surface at intervals, and two support pillars adjacent to each other are The upper and lower parts are connected by connecting bars.

Here, the connection bar connected to the upper end portion of the support column has a groove formed at the upper end portion of the hollow support column, and a hook provided at the end portion of the connection bar is locked in this groove.
And in order to improve the earthquake resistance of the article display shelf, a cap or a stopper is fitted into the hollow column so that the connecting bar whose hook is locked to the upper end of the column does not easily fall off ( For example, see Patent Documents 1 to 4.)

  However, the techniques described in Patent Literatures 1 to 4 are based on the premise that a back plate that closes the back of each shelf of the article display shelf is provided on the support column and the upper and lower connecting bars. By fixing the back plate to the support column and the connecting bar, a reinforcing effect for preventing the connecting portion between the support column and the connecting bar from being displaced in a plane along the back plate can be obtained. Therefore, when the back plate is not provided, there is a possibility that the connection strength between the support column and the connecting bar is insufficient, and improvement is desired in terms of earthquake resistance.

On the other hand, Patent Document 5 proposes a configuration in which an L-shaped connecting member is arranged at a connecting portion between a support column and a connecting bar. The connecting member is fastened to each of the support column and the connecting bar by passing the male thread portion through the abutting piece abutted against each of the support column and the connecting bar and screwing a nut into the male screw portion.
In this way, by providing a connecting member at the corner where the support column and the connecting bar intersect, the connection strength between the support column and the connecting bar is increased, and the connecting portion between the support column and the connecting bar is displaced in a plane along the back plate. It is possible to prevent effectively.

  By the way, when a support | pillar and a connection bar are hollow cylinders, if it is going to use a normal bolt and nut for fastening with a connection member, a bolt or a nut will be arranged in the hollow space of a cylinder support and a connection bar. It is necessary and work becomes very difficult. Therefore, Patent Document 5 employs a configuration in which a hook is provided at one end of the male screw portion and this hook is locked in an engagement hole formed in a support column.

JP 2005-192765 A Japanese Patent No. 3995221 JP-A-8-317839 JP 11-155709 A JP 2005-192767 A

However, in the technique described in Patent Document 5, since the male screw portion provided with a hook at one end is a special part, it takes time to manufacture it.
Further, at the assembly site of the article display shelf, it is necessary to fasten the connecting member to each of the support column and the connecting bar with the male screw portion and the nut, which takes time. Furthermore, in the state where the male screw part and the nut are not completely tightened during the assembly, the connecting member and the connecting bar cannot be fixed to the support column and become unstable, and there is a problem that the operation is difficult.
