Description

FIELD OF THE INVENTION The present application relates to pedestals in shelving devices, such as display shelves.

2. Description of the Related Art Conventionally, a pedestal in a shelf device such as a display shelf is formed by fixing a leg member in an L-shape to a lower end portion of a long stanchion in which a large number of locking holes are separated in a height direction. A shelf device is known in which the pedestals are laterally separated from each other, a hook provided at the rear end of the support arm is locked in the locking hole, and a shelf plate is placed between the support arms facing each other in the horizontal direction. is there.

However, according to the pedestal in the above-mentioned conventional shelf device, since the stanchion and the leg member are integrally formed, the transportation and packing of the shelf device is inconvenient due to the protrusion of the leg member. Along with
It is also inconvenient when changing the length of the leg member according to the purpose of use.

Therefore, in order to solve the above-mentioned inconvenience, the present application proposes a pillar provided with a locking hole in the lower part of at least one surface, and a rear end portion protruding rearward from the rear end surface and a tip end. Has a locking piece that projects from the lower surface and locks with the locking hole, and has a leg member that has a screw hole on the lower surface, and an intervening portion that intervenes the tip protruding portion of the locking piece at the rear portion, A connecting member provided with a mounting hole that matches the screw hole in the front part, and by locking the locking piece in the locking hole, the rear end surface of the leg member is brought into contact with one surface of the column, In addition, the connecting member is overlapped over the strut and the lower surface of the leg member, and the tip end protruding portion of the locking piece is interposed in the intervening portion, and the mounting screw is tightened through the mounting hole. Therefore, the protrusion of the tip of the locking piece is locked to the intervention part to connect and fix the column and the leg piece. In the above description, in order to further increase the strength of the connecting portion, the pillar is provided with locking holes at the lower left and right positions of at least one surface thereof, and the leg member is provided. Fix a pair of left and right locking plates separately provided with locking pieces for locking the locking holes to the left and right inner side surfaces of the rear end of the leg member, respectively, Locking plates fixed to the left and right inner side surfaces of the rear ends of the leg members, and further locking pieces provided on top of the locking pieces. In addition, the mounting screw has a conical head portion to firmly lock the protruding portion of the locking piece and the intervention portion, and the mounting hole of the connecting member has a conical lower portion. In addition, the mounting hole has a concave portion, and the center of the mounting hole is eccentrically provided rearward of the center of the screw hole.

Action However, during use, the locking piece of the leg member is inserted into the locking hole provided in the lower portion of at least one surface of the column, and the rear end surface of the leg member is in contact with the front surface of the column. Push down the leg member with to lock the locking piece in the locking hole, and in this state,
The lower surface of the column and the lower surface of the leg member are aligned with each other, and the tip of the locking piece projects from the lower surface of the column. Next, the coupling member is overlapped so as to straddle the lower end surface of the column and the lower surface of the leg member, and the tip protruding portion of the locking piece protruding from the lower surface of the column is intervened in the intervening portion of the coupling member, and then the mounting screw is attached. The lower surface of the pillar and the leg member are connected to each other by tightening the screw hole through the mounting hole.

In the above, the mounting screw has a conical head,
Also, if the mounting hole of the connecting member has a conical recess at the bottom and the center of the mounting hole is eccentric to the rear of the center of the screw hole, the mounting screw should be Since the head portion of the screw is eccentric and the connecting member is forcibly moved forward, the tip projection of the locking piece and the intervening portion of the connecting member are locked firmly.
