Description

The desk and chair legs support tools with a horizontal correction function}

The present invention relates to a foot rest for a book bench having a horizontal correction function, and more specifically, to form a concave-convex so that the bottom portion which is grounded with the ground symmetrical, and protrudes downward on a predetermined length on this uneven surface It is provided with a plurality of villi, the upper opening is provided with an insertion groove consisting of a predetermined space therein, the bottom surface forming the insertion groove of the plate-shaped reinforcement member that forms an arc shape seated By having a, the legs for the bookshelf is inserted into the insertion groove is supported on the top surface of the reinforcing member, so that the horizontal correction is possible on the curved ground or inclined surface without damaging the support hole by the bookshelf legs The present invention relates to a foot rest for a bookshelf having a horizontal correction function, such as the use of a stable stand.

In general, when manufacturing a desk or a stool, the packing is attached to the end of the leg with rubber or PVC to protect the floor or to cushion the load of the chair, but the attached packing is worn by the load or the surface is roughened to reduce the buffering effect. It will damage the floor. In order to prevent this, general homes and offices were made with a cloth cover and covered with tennis balls to prevent damage to the floor, but it was not only aesthetically beautiful but also had troublesome problems.

As a conventional technique for solving the above problems, the "supporting legs of the desk legs" of the Republic of Korea Registered Utility Model Publication No. 20-0217062 has been registered.

To explain this in more detail, on a bookshelf having an inclined leg with a pipe or a round bar, the bottom surface of the base coupled to the lower end of the inclined leg is formed to be inclined in the same direction as the inclined angle of the leg so as to have a wide cross-sectional area in contact with the ground. On the inclined surface, a plurality of fine protrusions are formed to prevent the chair from slipping on the floor. However, since such a configuration is provided with at least four or more ordinary inclined leg portions, it was virtually difficult to optimize the inclined surface at which the support holes of the above-described configuration are grounded to the ground at each lower end thereof. The problem is that the grounding force with the ground is reduced more than the support of the.

On the other hand, as shown in FIG. 1, when the ordinary booklet supporter 1 is positioned on the curved ground 500 having an irregular surface area, the predetermined angle (from the load acting vertically according to the degree of the curved surface) Since the clearance portion as much as θ) is generated, a load that acts on a chair or a desk causes a problem of severe shaking.

Therefore, the backrest supporter 1 to which the prior art is applied does not have sufficient grounding force with the ground 500. As a result, the backrest leg 10 is left in a part of the airborne state and is severely affected by the load. The problem of shaking could not be solved, and the end portion 12 of the pipe or round rod-shaped book holder leg 10 was penetrated through the support portion 1a of the book holder base 1 by frequent use. Exposed to the ground 500 and the friction noise and the ground 500 was not solved problems such as severely damaged.

The present invention has been devised to solve the above-mentioned problems, and the bottom surface is formed into a concave-convex shape having a certain regularity, and a large number of villi are formed on the bottom surface, thereby forming a plurality of villi, which are curved surface. It is an object of the present invention to provide a leg rest for a bench having a horizontal correction function which can perform a horizontal correction function of a desk or a stool by allowing the load to be evenly distributed even when grounding.

Another object of the present invention, by adding a reinforcing member of the plate-shaped body formed so that the bottom surface has an arc shape and the top surface is flat on the site surface that is in contact with the distal end surface of the book-like legs, applied from the book-like legs As well as distributing the load evenly, the legs of the bench stand are not damaged by the legs of the bench, so the legs of the bench with the horizontal correction function can be used to improve the durability and safer the bench by the load distribution. It is in doing it.
