The present invention relates to a leg height adjusting device and a desk having the same, and more particularly, a horizontally fixed leg height adjusting device that has a strong fixing force after adjusting the height between leg frames, and is easy to operate for height adjustment, and a desk having the same it's about

In general, a desk (desk) is a furniture used to read a book, write, or perform various tasks, and is used in schools, academies, offices, homes, etc., usually a top plate and a leg provided on the bottom of the top plate is made including

Most of these desks have a structure in which the height cannot be adjusted because the legs are integrally fixed to the top plate. In this case, it is impossible to inevitably cause inconvenience due to height fixation from the standpoint of users with various body structures, even though it is necessary to adjust the height of the upper plate according to the type of work.

As such, due to the necessity of adjusting the height of the legs for the desk, various products have been developed and used to satisfy them. has been presented

In this prior art, in the mechanism for adjusting the height of the desk, the upper leg is accommodated at a variable height by interposing a guide on the lower leg in which a plurality of through holes are formed, but the upper leg is in a state in which the hooking piece is exposed to the outside. The guide is provided with a tangent to the inside, and the guide is elastically coupled by a tightening nut in the incision groove and spiral on the upper side, and has an incision groove so as not to block the through hole of the lower leg.

However, in this prior art, the locking piece protruding by the spring does not protrude properly, the spring is compressed due to the load of the upper plate, etc., and the locking piece is inserted. there was.

In addition, the prior art has a problem in use and application that frequently occurs when the locking piece does not protrude properly from the through hole due to the elastic force of the spring in the process of actual use, which frequently requires maintenance and repair.

In order to solve the problems of the prior art, the present invention enables safe use by preventing the upper plate from falling undesirably by making the fixing force strong after adjusting the height between the leg frames, and the operation for adjusting the height is easy In addition, it has the purpose of increasing the convenience of use through convenient confirmation of the height.

In order to solve the above problems, according to an aspect of the present invention, a first leg frame in which a plurality of first fixing holes are formed along the longitudinal direction at one end; a second leg frame coupled to be adjustable in length by being inserted into the first leg frame and provided with a second fixing hole for connecting to a part of the first fixing hole; The first and second leg frames are installed around the second leg frame, the fixing protrusions are formed inside, and the fixing protrusions are detachably inserted into the first fixing holes through the second fixing holes. Fixing bracket to maintain this length-adjusted state; and a cover installed around the second leg frame so as to surround the fixing bracket.

In the fixing bracket, first and second fixing pieces arranged on the periphery of the second leg frame are connected to each other by a connecting pin, and the fixing protrusion may be formed inside the first fixing piece.

The second leg frame may be formed such that a plurality of coupling protrusions protrude outward, and the second fixing piece may have a plurality of coupling holes so that each of the coupling protrusions is fitted.

In the first leg frame, a plurality of display portions having the same distance as the first fixing hole are provided on the side portion, and the second leg frame is provided with display holes for selectively exposing any one of the display portions to the outside. , to check the adjusted length with the first leg frame.

The second fixing piece has an exposed hole that coincides with the display hole, and the cover is fitted downward from the upper side of the second leg frame and is at the upper end of the second leg frame by a locking part provided at the upper end. and an opening may be formed to coincide with the exposed hole.

According to another aspect of the present invention, the top plate; and a horizontally fixed leg height adjusting device according to an aspect of the present invention, provided in plurality on the lower surface of the upper plate, to adjust the height of the upper plate from the ground; including, a desk having a horizontally fixed leg height adjusting device is provided .

According to the horizontally fixed leg height adjusting device and the desk having the same according to the present invention, by making the fixing force strong after adjusting the height between the leg frames, the upper plate is prevented from falling undesirably to enable safe use, and the operation for adjusting the height This is not only easy, but also has the effect of increasing the convenience of use through convenient confirmation of the height.

1 is a perspective view showing a desk having a horizontally fixed leg height adjusting device according to an embodiment of the present invention.

Referring to FIG. 1 , a desk 500 having a leg height adjusting device according to the second embodiment of the present invention may include a top plate 510 and a leg height adjusting device 400 .

The upper plate 510 may be made of various materials including wood, synthetic resin, or stone.

1 to 6 , the leg height adjusting device 400 is provided in plurality on the lower surface of the upper plate 510, and the leg according to an embodiment of the present invention adjusts the height of the upper plate 510 from the ground. As a height adjustment device, it may include a first leg frame 410 , a second leg frame 420 , a fixing bracket 430 , and a cover 440 . The leg height adjusting device 400 may be structurally stable by being connected to each other by the reinforcing frame 530 .

A plurality of first fixing holes 411 are formed at one end of the first leg frame 410 in the longitudinal direction. Here, the first fixing holes 411 are configured to adjust the length of the legs by selection, and a plurality of first fixing holes 411 may be formed at equal intervals along the longitudinal direction on the side of the first leg frame 410 .

In the first leg frame 410 , a plurality of display units 412 having the same interval as the interval of the first fixing hole 411 may be provided on the side portion. The display unit 412 may imprint not only numbers indicating the steps of length adjustment, but also various characters or figures for identifying the steps of length adjustment.

The second leg frame 420 is coupled so that the length can be adjusted by inserting the first leg frame 410 therein, and a second fixing hole 421 for connecting to a part of the first fixing hole 411 is provided. do. Accordingly, by the coupling of the first and second fixing pieces 431 and 432 using the connection pin 433 to be described later, together with the fitting of the first and second fixing holes 411 and 421 by the fixing projection 431a, the coupling of the first and second fixing pieces 431 and 432, It is possible to enable a firm coupling between the first and second leg frames (410, 420).

The second leg frame 420 has a display hole 422 that selectively exposes any one of the display units 412 to the outside, so that the adjusted length with the first leg frame 410 can be checked. That is, the display hole 422 exposes the display portion 412 of the first leg frame 410 inserted into the second leg frame 420 to the outside, thereby determining the position according to the inserted length of the first leg frame 410 . The differently displayed display unit 412 is selectively exposed to the outside, and through this, the degree of adjustment of the length of the leg can be recognized.

The fixing bracket 430 is installed on the second leg frame 420, and the first and first fixing protrusions 431a are detachably inserted into the first fixing hole 411 through the second fixing hole 421. The two leg frames 410 and 420 maintain the length-adjusted state.
