Description

Support for height adjustment {Sink height adjustment feet}

The present invention relates to a support leg for height adjustment, and more particularly, to be inserted into an installation hole provided on the lower surface of a furniture to guide the fixing position of the fixing part with respect to the lower surface of the furniture, and is detachably coupled to the fixing part. It relates to a support leg for height adjustment having a guide to be.

If furniture such as a locker or closet including a sink is not installed horizontally, deformation due to twisting or shaking occurs, reducing durability. Even when installed horizontally, it is easy to be leveled due to external shocks such as changes in storage form or repeated opening and closing.

Typically, furniture is installed on a generally flat floor surface. Furniture made of a flexible material such as wood causes a problem of being crooked or tilted during use if the height of the floor is not constant. As such, it is unavoidable that the bottom surface is generally bumpy even if the floor surface is generally flat, so furniture installers generally use rubber, paper, and plastic materials as a medium to smooth the height of the furniture to make it constant. will do the work.

However, the smoothing work using rubber or paper as a medium causes the inconvenience of placing the rubber or paper between the lower part of the furniture and the floor with a considerable height by folding the rubber or paper several times when the floor surface has severe curvature, and the difficulty of precise height control. Difficulties follow.

Therefore, height control feet or control devices for furniture are used to level the furniture when it is installed or distorted during use.

Since the conventional height adjusting device for furniture is structured to go up and down by turning the adjusting ring, the inside of the furniture, that is, the control foot in contact with the wall is not exposed so that it can be turned by hand. There is a problem that this is possible, and there is a disadvantage that it is impossible to adjust the height of the rear height adjusting device during use while storing objects inside.

In addition, since the front and rear legs fastened under the furniture are designed to level the furniture by directly turning them, the front legs of the furniture can be easily turned, but the rear legs inside the furniture cannot be easily turned.

In particular, when the furniture is installed in the corner, it is inconvenient to adjust the rear legs at the corner while turning, and when the furniture is sandwiched between the furniture, the rear legs cannot be easily turned because the furniture is placed on both sides. If it is not level, it is very inconvenient to level the furniture while repeating the work of removing the furniture, turning the rear legs, and then putting it back in, so related prior arts have been proposed.

The proposed prior art furniture height adjusting device (Korean Patent Registration No. 10-1513267) relates to a furniture height adjusting device installed under the fingerboard of the furniture, and is fixed to the lower body supported on the floor and the fingerboard. An upper body portion that is threaded with the lower body portion and raised and lowered by the rotation of the lower body portion, a rotating portion rotatably installed in the upper body portion to provide rotational force to the lower body portion, and a rotating portion installed in the lower body portion and fitted to receive the rotational force of the rotating portion Characterized in that it includes a fitting portion. Therefore, the present invention has the effect that the height of the furniture can be adjusted at any time by the rotation of the rotating part by combining the upper body with the lower body and combining the rotating part with the fitting part formed in the lower body to rotate the lower body and raise and lower the upper body. provides

In the case of the prior art, since a device applied with one method among several methods for adjusting the height is used, when installing fixed furniture such as a sink, a different method is applied in order for the constructor to change the height adjustment method in consideration of the installation site conditions. There is a problem that requires the purchase of additional products.

Korean Patent Registration No. 10-1513267 : Furniture height adjustment device

The present invention was created to solve the above problems of the prior art, and the height of the furniture can be adjusted by a rotating tool inside the furniture or by a rotational force applied from the outside of the furniture. Its purpose is to provide
