Description

[Detailed description of the invention] The present invention relates to an adjuster that is installed at the bottom of the leg plate of an assembly type display stand, etc., and finely adjusts the standing angle of the display stand, etc. according to the installation floor. To provide an adjuster for a leg plate in a display stand, which can perform reliable and effective load support and fine height adjustment with a simple configuration even when the leg plate is composed of one thin plate.

Since the leg plates of conventional azimuth stars were usually quite thick and heavy, many of them were simply made by screwing bolts etc. from below into screw holes provided on the bottom surface of the leg plates, and the leg plates were made of a single piece. In the case of a thin plate, in order to prevent breakage of the leg plate and to reliably support the load, a special separate part must be manufactured as an adjuster star, or an adjuster star cannot be provided.

This idea was created in view of the above circumstances.
The lower edge of the leg plate is a bent edge, a notch is provided at the corner of the bent edge, a protrusion that can fit into the notch from the bent edge side, and a flange that abuts against the surface of the leg plate, and is in contact with the upper surface of the bent edge. The gist is that the azimuth star nut that is in contact with the azimuth star bolt is screwed upward from the bottom surface of the leg plate with the azimuth star bolt that is placed upside down on the installation floor, and the tip of the azimuth star bolt is brought into contact with the upper edge of the notch. It is.

The details of the present invention will be explained in detail using the accompanying drawings. Figure 1 shows the front main part of a leg plate A formed of a single thin plate, which is hooked to the front surface of a column (not shown), and is attached by a bent vertical piece 1, a bent horizontal piece 2, etc. on the upper edge of the leg plate A. The lower part of the display stand is shown, which is constructed by attaching a base plate 3, a hook plate 6, etc. to which hooks 5 formed on both side edges are fitted and hooked to hooks 4 protruding from the tips of the leg plates A. The adjuster according to the present invention is provided on such a leg plate A in order to finely adjust the horizontality of the board 3, the upright angle of the support, etc. according to the unevenness, slope, etc. of the installation floor. A notch B is formed at the bent corner of the bent edge 7 formed by bending the edge to one side, that is, the corner including the leg plate A side and the bent edge 7 side across the corner. It can be installed using B. That is, as shown in FIG. 1, this notch B has a thin groove 8 opened downward on the upper part of the leg plate A side in which the tip of an adjuster star bolt D, which will be described later, can be placed, and at least a narrow groove 8 on the lower part. A notch is provided to form a wide part 9 having a large width and a height that allows at least an adjuster nut C (described later) to fit therein, and the bent edge 7 side is provided with a notch that is at least inverted on the installation floor as shown in FIG. Form a portion where the adjuster star bolt D that abuts directly below the end edge of the leg plate A can be positioned, preferably an inner edge that has approximately the same size as the radius of the adjuster star bolt D and can be positioned close to the inverted adjuster star bolt D. Both have continuous notches. As shown in FIG.
In the illustrated example, which has a protrusion 10 that can be fitted into the flange 10 and a flange 11 that abuts against the surface of the leg plate A on the inner edge of both sides of the wide portion 9, the screw hole 12 is convex in plan view.
As shown in the figure, the adjuster star bolt D is provided at a position where the adjuster star bolt D can be positioned directly under the leg plate A with the flange 11 abutting against the leg plate A surface.

Since the tip of the adjuster star bolt D is in contact with the inner edge of the top of the narrow groove 8 in the notch B and the lower surface 13 is in contact with the installation floor, the load acting on the leg plate A itself can be directly transferred. This is transmitted to the installation floor. In the direction perpendicular to the leg plate A surface, that is, in the front-rear direction, the flange 11 of the adjuster star nut C screwed onto the adjuster star bolt D is in contact with the leg plate A surface, and the adjuster star bolt D is in the notch B. By hitting the inner edge on the bent edge 7 side,
In the direction along the surface of the leg plate A, that is, in the left-right direction, the protrusion 10 of the adjuster nut C forms a wide part 9 with a notch.
In addition to being fitted, the adjuster star bolt D is located within the narrow groove 8, so that the position of the adjuster star bolt D can be reliably regulated. Furthermore, in order to finely adjust the position of the leg plate A in the vertical direction, the adjuster star bolt D is rotated, and the screwed adjuster star nut C is raised to abut against the top edge of the wide part 9 in the notch. After that, if the adjuster star bolt D is further rotated in the same direction, the load acting on the leg plate A is transmitted through the adjuster star nut C to the adjuster star bolt D whose lower surface 13 is in contact with the floor, and the adjuster star bolt D is rotated. Just like when the load is transferred from the tip, it can be supported directly on the installation floor.

The adjuster of the leg plate in the display stand of the present invention constructed as described above can be configured by providing a notch at the corner of the bent edge formed on the lower edge of the leg plate, so that the adjuster nut and the adjuster bolt can be attached to each other even when the leg plate is composed of a single thin plate. It can be realized with a simple configuration of just combining the two parts, and an adjuster star nut is fitted into the wide part of the leg plate side of the notch from the bent edge side, and an adjuster star bolt whose lower surface is in contact with the floor is screwed together. The tip of the star bolt, which is the protruding part above the azimuth star nut, was fitted into the narrow groove at the top of the notch and positioned directly below the leg plate, so that the azimuth star nut and, by extension, the azimuth star bolt in the front and back direction.
It is possible to prevent displacement in the vertical direction and in the direction of the leg plate, thereby ensuring reliable and effective load support.
