Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf holder for preventing each shelf plate used in a bookshelf, a rack made of steel or the like from falling even when an earthquake occurs.

[0002]

2. Description of the Related Art As a receiving member for receiving and supporting each shelf plate used in a bookshelf, a rack made of steel or the like, there has been a shelf receiving device conventionally. The shelf receiving device according to the related art is roughly classified into an opening formed in the left and right inner side walls of a bookshelf or the like, or a hook portion hooked in the opening formed in a rail surface fixed to the inner side wall, and A metal plate having a vertical plate surface portion along the inner wall or the rail surface, and a shelf receiving portion provided so as to project laterally from the lower portion of the vertical plate surface portion, and a shelf such as a bookshelf at one end of the shelf receiving portion. In some cases, dowels are formed so as to project into openings formed in the left and right inner side walls. Of these, the former shelf receiver has a structure in which the hook portion is simply hooked to the opening, and the latter shelf receiver has a structure in which the dowel is inserted into the opening and locked. Is something
It has a structure in which a shelf plate is placed and supported on a shelf receiving portion that is a part of these shelf receiving devices.

[0003]

However, in the case of the shelf holder having a structure in which the hook portion is simply hooked on the opening to be hooked, the shelf holder bounces upward when an earthquake occurs. , It sometimes slipped out of the hole and dropped the shelf board. If this happens, not only the books and shelves will be scattered, but also the books and shelves will be damaged, and further, the books and shelves that have fallen will cause secondary damage such as damage to people in front of the bookshelf. was there. On the other hand, with a shelf holder having a structure in which the dowel is inserted into and locked in the opening, the dowel often comes off the inside of the opening and drops the bookshelf. Since the holes are often formed directly on the left and right side plates of the bookshelf, even if you try to adjust the mounting height of the shelf plate in multiple stages by providing a large number of openings on the left and right side plates, Strength of
In particular, there was a problem because the strength between the upper and lower openings was reduced.

Under the circumstances described above, the present inventor has
We learned that there are many cases where the former shelf receiver mentioned above slips out of the opening in the event of an earthquake and drops the shelf board, and even when an earthquake occurs, the shelf receiver will slip out of the opening. We have started to develop a shelf holder that will not come off. Then, as a result of earnest studies and studies after that, finally, the invention of the novel shelf receiver according to the present invention was created, and the prototype was completed.

The present invention, which has been completed through the above-mentioned circumstances, can be carried out by one-touch even when it is mounted on the rail, and can be easily detached, and can be mounted on the rail. For the downward pressure from the shelves and books placed on the shelves, the hooks receive this downward pressure, and the upward pressure generated when an earthquake occurs It can be caught by the locking member that is rushed in and locked, and it can be firmly fixed to the rail, and even if an earthquake occurs, the shelf receiver will come off from the rail and drop the shelf board An object of the present invention is to provide a shelf holder that can prevent the occurrence of the above.

[0006]

The invention according to claim 1 proposed for solving the above-mentioned problems is an opening formed in the left and right inner side walls of a bookshelf or the like or a rail fixed to the inner side wall. A shelf receiver main body having a hook portion for hooking, a vertical plate surface portion along the inner wall or a rail fixed to the inner wall, and a shelf receiving portion provided to project laterally from a lower portion of the vertical plate surface portion. The vertical plate surface portion is provided with a locking member that projects into the opening that holds the hook portion or the lower opening thereof to prevent the rack receiver body from swinging and coming off. It is a shelf holder.

The shelf receiver of the present invention can be hooked on the left and right inner walls of a bookshelf or the like by the hook portion at the upper end thereof, and
By locking the locking member that protrudes to the rear of the vertical plate surface into the hole and locking it, the shelf holder will not be accidentally shaken or slipped out, especially when an earthquake occurs. When you do, make sure the shelves do not bounce or fall. Moreover, this locking member can be easily removed from the opening by a simple operation and attached to the opening of a step having a different height. The shelf receiving portion is not limited to the one formed by bending the lower end portion of the vertical plate surface portion, but may be one attached afterwards to the vertical plate surface portion.

According to a second aspect of the present invention, the locking member used in the shelf holder according to the first aspect applies an elastic force or a biasing force to at least one edge of the peripheral edge of the opening. A shelf receiving member that is formed of a resin or rubber protrusion or a substantially Ω-shaped body having a locking portion that locks with it, or is formed of a leaf spring is used.

According to the second aspect of the present invention, there are roughly two types of locking members. One of the locking members is a resin or rubber protrusion or a substantially Ω-shaped body having a locking portion that locks with at least one edge of the peripheral edge of the opening with an elastic force or a biasing force. It was done. When the locking member is formed of a resin or rubber protrusion or a substantially Ω-shaped body in this way, the rack holder is held by hand after the hook on the top of the rack holder is hooked in the opening. Just by pushing this toward the rail, the head of the locking part protruding to the rear side of the vertical plate surface is pressed against the upper and lower edges of the opening, and its shape is slightly deformed. And easily plunge into the opening. Moreover, after the plunge, the locking portion formed in the middle of the locking portion fits into the stepped portions at the upper and lower edges of the opening, and the biasing force acts in the locking direction in this state. Moreover, the locking member cannot be accidentally removed from the inside of the opening. That is, the shelf receiver does not bounce or fall off even when an earthquake occurs, for example.

The other type of locking member is formed of a leaf spring. This leaf spring is preferably a leaf spring having a substantially L-shaped side surface or a substantially inverted L-shaped bent angle slightly exceeding a right angle. The locking member having a substantially L shape in a side view is arranged such that the horizontal surface thereof is in a position where the locking member projects into and locks in the lower opening of the opening in which the hook portion of the vertical plate surface portion of the shelf holder is hooked. , Is fixed to the vertical plate surface portion. On the other hand, the locking member having a substantially inverted L shape in side view is fixed to the vertical plate surface portion such that the horizontal surface thereof projects rearward from the upper end of the vertical plate surface portion of the shelf holder. ing. The L-shaped locking member as viewed from the side easily penetrates into the opening when a force that resists the biasing force is applied to the substantially horizontal surface. Side view reverse L
The shaped locking member is pushed into the opening while being pressed with a fingertip. In both cases, after the plunge, the urging force acts in a direction in which the substantially horizontal surface spreads slightly and abuts against one edge of the opening, so that it cannot be accidentally slipped out of the opening. That is, the shelf receiver does not fall out of the opening even when an earthquake occurs, for example. That is, the shelf is not dropped.

According to the invention described in claim 3 below, the rear end of the elastic body in the shelf receiver according to claim 1 or 2 is
It is a shelf holder provided with an operation portion for releasing an engagement toward an edge of an opening by biasing the elastic body.

This operating portion is required especially in the case of the above-mentioned substantially inverted L-shaped locking member. This hooking member is inserted into one opening such that the hook is in contact with the lower edge of the opening and the locking member is in contact with the upper edge of the opening, so that when the hook is removed from the opening, Since the locking member becomes a resistance, in such a case, first, the operating member is operated to retract the locking member to the outside of the opening, and in this state, the hook is removed from the opening. As a preferable example of the operation portion, one in which a part of the leaf spring is projected in the vertical direction is given.
