Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an adjuster device that is attached to a base member that supports supports constituting a bookshelf, a screen panel, an exhibition panel, or the like.

[Conventional technology]

In the conventional adjuster star device, a through hole is formed in the bottom plate of a base member, a nut having a screw hole is connected and welded to the top surface of the bottom plate, and a screw shaft having a ground plate at the lower end is screwed into the screw hole of the nut. When welding a nut inside a base member, the nut was temporarily fixed and then a welding tool was inserted through the end opening of the base member. It was time consuming and the precision of the nut fixing position was poor. In addition, as disclosed in Japanese Utility Model Publication No. 58-22595, a through hole is formed in the bottom plate of the base member made of a hollow cylinder, and a screw hole is provided in the center of the engaging hole provided opposite to both side plates. Disclosed is a removable and easy-to-install adjuster device having a structure in which a plate-shaped adjuster receiver is inserted from the side, and an adjuster star bolt is inserted through a through hole and screwed into the screw hole of the adjuster star receiver. On the other hand, since the adjuster star receiver is only supported at a fixed height so as not to rotate relative to the adjuster star bolt, the adjuster star receiver may be displaced in the direction of insertion into and removal from the engagement hole, resulting in damage to the upper structure. This had the problem of causing objects to shake or wobble.

[The problem that the idea aims to solve]

The present invention aims to solve the above-mentioned situation by making it possible to reliably position the adjuster receiver inside the end of the base member and easily fix it by welding means such as spot welding. The object of the present invention is to provide an adjuster device that is robust under certain conditions.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention has been developed by forming a lower piece by bending the lower edges of a steel rod having a U-shaped cross section and facing each other and bending them inward. A base member formed by bending the inner edge of the lower piece upward to form a hanging piece, and cutting out the ends of both hanging pieces in a stepped manner to form a horizontal mounting edge and a stop edge; A vertical plate inscribed in both side plates is bent on both sides of the substrate placed on the mounting edge of the base member, and a through hole is formed in the center of the substrate, and a through hole is formed on the lower surface of the substrate. A nut having a screw hole is fixed or a screw hole passing through the top and bottom is formed, and the substrate is placed on the mounting edge, and both vertical plates are brought into contact with the inner surfaces of both side plates, and the inner edge of the substrate is placed on the mounting edge. A steel adjuster receiver is made by welding a vertical plate to the side plate of the base member while it is in contact with the stopper, and a ground plate is fixed to the lower end, and the upper part can be adjusted up and down through the screw hole of the adjuster receiver. An adjuster device is constructed that includes an adjustment member that is a screw shaft that is screwed together.

[Effect]

The adjuster device of the present invention, which has the above-mentioned contents, places the base plate of the adjuster receiver on the mounting edge formed by cutting out the vertical piece at the end of the base member into a plate shape, and also attaches both vertical plates to the base member. The vertical plate and the side plate are fixed by spot welding, with the inner edge of the base plate abutting against the abutting edge provided on the vertical piece for secure positioning, and If the upper part of the screw shaft of the adjustment member is screwed into the screw hole of the nut provided in the center of the base plate of the receiver or the screw hole formed directly on the base plate, the vertical height can be adjusted, and the nut is fixed at that time. The upper end of the screw shaft was made to protrude upward from a through hole formed in the substrate.
