BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for a shelf plate and a supporting leg in a transferable shelves or the like.

[0002]

2. Description of the Related Art Conventionally, a fixing device for a shelf plate and a supporting leg in a shelf of this kind has been designed such that a tightening screw which is inserted through the leg rod from outside the front and rear leg rods of the supporting leg is directly screwed into an end portion of the shelf plate. Then, a means for tightening is adopted.

[0003]

By the way, in the above-mentioned conventional fixing means, since the tightening screw is passed through both leg rods and screwed into the end portion on the side of the shelf plate for tightening, the shelf plate is a supporting leg. On the other hand, it can only be fixed at a certain height, and it is difficult to adjust the shelf plate up and down as necessary. Also, in order to be able to adjust the upper and lower sides of the shelves appropriately, when a large number of screw insertion holes are provided in the two rods in rows, it is time consuming in processing and it is impossible to do so. Providing a large number of holes in the rod has the drawback of reducing the strength of the leg rod. Therefore, in the present invention, an improved device was devised to eliminate the drawbacks of the conventional example, and a fixing device for the shelf plate and the supporting leg, in which the upper and lower parts of the shelf plate were adjustable without lowering the strength of the supporting leg, was devised. An object of the present invention is to provide a fixing device that can safely install a shelf board as a supporting leg having a strong supporting force of the shelf board.

[0004]

Means for Solving the Problems In a shelf in which both end portions of a shelf plate are fixed to both left and right supporting legs, a husband fixing tool is fitted from outside the front and rear leg rods of the supporting leg, and the fixing tool is attached. The fixing tool is configured to be screwed to an end portion on the shelf board side, and the fixing tool has a concave portion for fitting to a lever rod on one side of a U-shaped synthetic resin piece on a plane, and the other side. On the side, a screw insertion hole is provided in the horizontal direction orthogonal to the concave portion, and a protrusion directed toward the shelf plate side end surface is provided inside the outer end portion on the screw insertion hole side. By abutting against the side end face and fitting the recess to the outer side of the leg rod, a space is created between the vertical inner surface between the projection and the recess and the end face on the shelf board side, and the gap goes from the screw insertion hole to the end surface on the shelf plate side. Of the shelf plate and the supporting legs by fixing the ends on the shelf plate side to the supporting legs by crimping the fixing tool and the leg rod by screwing the tightening screw. A constant apparatus.

[0005]

[Operation] The fixing tool is fitted to the outer side of the front and rear leg rods of the support leg by the concave portion on one side, and the protrusion protruding on the outer end portion on the other side is brought into contact with the end surface on the shelf board side, and the screw insertion hole is formed from the outside. Then, by tightening the tightening screw toward the shelf plate side end surface, the recess of the fixture will be crimped to the outer side surface of the leg rod, and the inner side surface of the leg rod will be crimped to the shelf plate side end face, and the outer end portion of the fixture will be pressed. Since the tip of the inner inward projection is pressed against the end surface on the shelf side, the end on the shelf side is fixed to the support leg via the fixing tool without lateral swing, and the shelf plate is stable without shaking. In this case, the outer end projection of the fixture abuts the shelf plate side end surface, and the vertical inner surface between the projection and the recess is separated from the shelf plate side end surface by a gap, so tightening this with the tightening screw The contact point of the projection tip serves as the fulcrum, the screw tightening portion of the tightening screw serves as the power point, and the recess serves as the point of action. Prevents twisting of the shelves by crimping at the points and stabilizes the shelves. By loosening the tightening screw of the tightening screw, the fixture can be uncompressed with the leg rod and the end surface of the shelf plate side, so the shelf plate can slide up and down along the supporting leg, and the upper and lower shelves can be freely moved. Easy to adjust to.
