Abstract

The present invention relates to a desk and chair leg cap coupled in ends of the desk and chair legs. The desk and chair leg cap has an insertion fixing piece retained to have a constant space from an inner surface of a cap body in the cap body of which one side is opened, and of which the other side is closed. The insertion fixing piece is formed in a hollow type of which the inside is empty, and a horizon fitting part is formed between an inner circumferential face of the cap body and an outer circumferential face of the insertion fixing piece. In the horizon fitting part, a fitting space of a finishing end in which an insertion of legs is finished is formed smaller than a start end in which the insertion of the legs is started, so that the legs are formed to be inserted by a stationary fit. A plurality of subsidiary pressure liners having an axial direction are formed to have a constant space in the outer circumferential face of the insertion fixing piece, and a spacer piece is integrally formed to have a circular arc shape along an outer circumferential face of a lower part of the outside of the cap body. In the middle of the bottom of the spacer piece, a cut groove having a longitudinal direction is formed, so that the bottom of the cap body is separated from a floor. Contact parts are formed on both sides of the cut groove to come into contact with the floor. Therefore, the present invention interrupts losing the cap by preventing the cap body from being separated in the course of moving a desk and a chair, and interrupts formation of a skid mark in the middle of the floor, the skid mark allowing elements to be easily moved with little power by the spacer piece formed on the cap body.

Description

{Desk and chair legs cap}

The present invention relates to a leg cap for a chair and foot, and more particularly, to a cap body having a spacer piece at an end of a leg for legs and legs.

Generally, there is a desk and a stool in the classroom as a way to sit and read and write.

The desk is provided with a support leg which is formed by bending a pipe, a top plate coupled to the upper end of the support leg, and a storage box for storing books, notes and writing utensils, and a bag or shoe bag It consists of a hook.

The stool is composed of a frame which is connected to the upper part of the supporting leg, and the seat and the backrest are combined so that the seat can be easily seated by the student or the user.

The support leg supporting the book and the stool is provided with a horizontal member having a horizontal shape parallel to the floor at a lower portion of a vertical member having a vertical shape for maintaining the height at a predetermined height from the floor, .

On the other hand, the horizontal member has sufficient supporting force in a state where the lower part of the horizontal member is seated so as to be wholly opposed to the floor, but it has difficulty in moving when the book and the stool are moved.

In addition, since the both ends of the horizontal member are exposed, there is a problem that the floor is scratched. In the state where the floor is not flat, it is difficult to align in parallel and one of the desk or stool is sagged, that is, .

In order to solve these problems, a protective cap is usually attached to both ends of the horizontal member, thereby preventing the floor from being scratched at the time of moving the book or the stool.

However, in the process of moving the book and the stool, there is a problem that the protective cap coupled to both ends of the horizontal member is easily detached, and when the protective cap is lost due to such a problem, there is the same problem as described above.

In addition, when the lower portion of the protective cap is kept in contact with the floor as a whole, friction is generated between the protective cap and the floor when the book is moved without lifting the stitches. Thus, There is another problem that the floor becomes dirty.

The present invention can be easily moved while preventing the leg cap separated from the legs supporting the legs supporting the legs from being lost and minimizing the area contacted by the feet in the process of being directly in contact with the floor So as to prevent the skid marks from being generated on the floor by reducing the friction generated in the process, thereby preventing the occurrence of stains on the floor.

The present invention relates to a leg cap (A) coupled to an end of a leg and a leg, wherein the leg cap (A) has a cap body (10) inside a cap body (10) The insertion fixing piece 11 is formed in a hollow shape having an inner space and the inner peripheral surface of the cap body 10 and the insertion fixing piece 11 The horizontal fitting portion 105 is formed with a fitting end 105 of the finishing end portion 112 to which the insertion of the leg is finished more than the starting end portion 111 where the insertion of the leg starts, A plurality of auxiliary pressurizing liners 113 having an axial direction are formed at regular intervals on the outer circumferential edge of the insertion fixing piece 11, 10 so as to have an arc shape along the outer periphery of the lower outer side The spacer piece 12 is integrally formed with a cutout groove 121 having a longitudinal direction at a lower center thereof so that a lower portion of the cap body 10 is spaced from the bottom, Contact portions 122 are formed on both sides of the base 121 to make a line contact with the bottom.

In addition, the insertion and fixing piece 11 is formed to have a shape drawn inward from an inlet of the cap body 10.

Also, the leg cap A is characterized in that the cap body 10 and the insertion fixing piece 11 are injection-molded by synthetic resin.

The leg cap (A) is characterized in that an inclined portion (101) is formed in which the open inlet side of the cap body (10) is lowered from the upper portion of the leg to the lower portion of the inner side.

The present invention is advantageous in that the cap body can be prevented from being detached in the course of moving the book or the stall by allowing the cap body to be coupled to the end portion of the book and the leg opening.

In addition, it is possible to prevent the cap body from being lost more.

In addition, by forming the spacer piece at a portion where the cap body touches the floor, the contact area that comes into contact with the floor can be minimized, and the book and the stool can be easily moved with a small force.

In addition, it is possible to prevent friction marks, that is, skid marks, from being formed in the process of pushing the book or the stool from the floor, thereby making it possible to clean the floor.

This further enhances the life of the cap body.
