Description

[Detailed description of the invention] <<Industrial application>> This invention prevents panel mounting members such as cabinets, table top holders, bookshelves, etc. that are attached to partition panels from falling off unexpectedly after being connected to the panel. This relates to a device for preventing falling off.

Conventionally, when attaching a panel-shaped top plate holder that contacts the floor to a partition panel, downward locking claws provided at the rear end of the top plate holder are connected to engagement holes provided at predetermined intervals in the vertical direction of the panel. It was tightly engaged.

For this reason, when adjusting the level of the top plate, if you raise the top plate support by turning the adjuster provided on the bottom of the top plate support, or if you accidentally lift the top plate support to move it, the downward engagement will occur. This is very dangerous as the retaining claws are removed from the engagement holes and the connection between the panel and the top plate holder that supports the panel is released, causing the panel to fall over, which is very dangerous.

《Purpose and structure of the present invention》 The purpose of the present invention is to improve the above-mentioned drawbacks.
After the panel mounting member and panel are connected, they do not move independently in the height direction, but always move as one, preventing the panel mounting member from coming off unexpectedly. The purpose is to provide a
A downward locking claw that engages with the engagement hole provided at a predetermined interval in the vertical direction of the panel, and a locking claw that can freely move in and out of the engagement hole are provided. It has an in/out part that can be moved in and out, and an operation part for making the in/out part escape from the engagement hole, and the in/out part is always biased in the direction of fitting into the engagement hole, and the locking claw is engaged. The lock pawl is provided at a height such that it can move in and out of other engagement holes only when it engages with the partition wall between the holes.
