Description

Height adjustable desk {DESK POSSIBLE HEIGHT CONTROL}

The present invention relates to a height adjustable desk.

More specifically, it is a kind of an auxiliary table (desk, desk, etc.) which is used by putting a predetermined article on it, and it is possible to adjust the height of the plate on which the article is placed, The present invention relates to a desk capable of height-adjustable for allowing a user to sit or stand.

In a company or school, there is a desk for people to sit on, a computer and a book for convenient work or education.

Since the conventional desk is made uniform in height uniformly, there is no separate function for adjusting the height.

People who work or take classes in the above space sit for most of the time, so the scoliosis of the spine is distorted, and the distance between the book and the eyes placed on the desk is not in focus. Stress builds up.

As a result, there is a problem in that it is difficult to perform efficient work because the healthy mind and physical growth are adversely affected.

In recent years, a desk which can be used in a standing state by combining a computer and a support having a relatively long length on the bottom surface of a top plate on which a book is supported is widely used. However, since it is more tiring to stand for a long time in order to work, there is a limit to solve the above-mentioned problem with such a desk.

Regularly taking a rest from stretching, exercising, etc. from sitting for a long time can have a positive effect on the body or mind, but there are a lot of limitations in considering the situation of modern people performing heavy work.

Accordingly, an ergonomic desk which can continuously perform tasks while considering the health of the user is required.

In response to this demand, various types of height adjustment desks have recently been introduced. Some of the height adjustment desks have a shape in which a whole desk is moved up and down using a motor. However, this requires an actuator such as a motor There is a problem that the manufacturing cost is increased and the structure is complicated.

As another example of the height adjusting desk, there has been disclosed a form in which a user can manually adjust the height of a desk, including an elastic member such as a spring and a link member connected thereto. The manually operated height adjusting desk as described above has an advantage in that the structure is simple and the manufacturing cost is low, but the structure is relatively unstable.

Particularly, there is a problem that the desk member can not be stably supported and shake because the link members supporting both sides of the desk move independently of each other even in the process of adjusting the height and in the state where the height adjustment is completed and fixed.

In order to solve such a problem, a height adjustable desk is disclosed in Japanese Patent Application Laid-Open No. 10-2017-0127389.

The above-described technique includes a base, an upper plate having a height varying with respect to the base, a first connecting member connecting the base and the upper plate, and a second connecting member connecting the base and the upper plate, And at least one of the first connecting member and the second connecting member has a bent gap forming portion.

As another technique, a height adjustable desk is disclosed in Japanese Patent Application Laid-Open No. 10-2017-0127387.

The above-described technique includes a base, an upper plate having a height varying with respect to the base, a first connecting member connecting the base and the upper plate, and a second connecting member connecting the base and the upper plate, And a height adjustment mechanism installed to connect the first connection member and the second connection member, wherein the first connection member and the second connection member cross each other to form a first plane, The height adjusting member moves on the first plane in accordance with the lifting or lowering of the upper plate.

As another technique, a height adjustable desk is disclosed in Japanese Patent Application Laid-Open No. 10-2017-0127386.

The above-described technique includes a base, an upper plate having a height varying with respect to the base, a first connecting member connecting the base and the upper plate, a second connecting member connecting the base and the upper plate, A cylinder connected to the first connecting member and the second connecting member so as to be spaced apart from the rotating shaft and connected to the other of the first connecting member and the second connecting member; And a piston rod inserted in the cylinder and arranged to face the upper plate.

On the other hand, Japanese Laid-Open Patent Publication No. 2011-031018 discloses a chair as a crib with similar principles.

The technique describes an upright chair in which the seat for seating is adjustable in height from the ground.

The above-described techniques describe a configuration for adjusting the height of a desk (table) and a chair, but have a structure different from that proposed by the present applicant.
