Abstract
A height adjustable desk according to an embodiment of the present invention includes a lower plate, an upper plate connected to the lower plate and a plurality of connecting members so as to be vertically movable, a rail portion mounted on a bottom surface of the upper plate, And the other end of the connecting rod is connected to at least one of the connecting member and the lower plate to adjust a descending speed or a height of the upper plate.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a desk capable of adjusting height and height, and more particularly, to a height adjustable desk for efficiently adjusting a height and a descent speed by additionally providing a connecting member having an improved structure between an upper plate and a lower plate.
Generally, most people, such as students and workers, sit at a desk and work for a long time. These habits are harmful to human health because they cause muscles, skeletal diseases and metabolic diseases. According to one medical study, sitting for a long time increases the mortality rate, especially cardiovascular disease, diabetes and obesity-related mortality, and most people who sit at most times are 50% more likely to die from heart attacks than those who do not I am investigating.
This means that sitting will stop the circulation of the lipase, the fat digestive enzyme, while standing is promoting the distribution of lipase to treat fat and cholesterol as the muscles are involved regardless of the time spent on exercise Because.
However, if most students and workers work a lot of time while working, they become more fatigued, and the additional burden of the circulatory system can increase the risk of arteriosclerosis and increase the risk of varicose veins. In addition, since the environment and facilities that can stand and work in offices and schools are not provided properly, standing and working are difficult to realize realistically.
Therefore, when sitting for a long time, it is desirable to work regularly or intermittently, and it is also possible to improve the concentration and lose weight due to the consumption of calories.
Accordingly, desks and devices have been developed to avoid sitting for a long time and to be able to continue working periodically or intermittently, and a desk or apparatus has been developed and disclosed in the "Desk " of Patent Application No. 10-2010-0070343 This function is also disclosed in the " upper plate height adjusting device ".
However, this technique is not easy to adjust the height, has a problem of falling rapidly when a load greater than a certain size is applied, and is inconvenient to be applied to a conventional desk. In addition, a separate hydraulic or pneumatic pressure must be included to complicate the structure of the desk.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus and a method for protecting a loaded equipment from rapid descent shock by controlling a descending speed according to a load of each apparatus, The present invention provides an economically excellent height adjustable desk that can be used for assisting an existing desk and can be easily moved without requiring additional space for installation.
A height adjustable desk according to an embodiment of the present invention includes a lower plate, an upper plate connected to the lower plate and a plurality of connecting members so as to be vertically movable, a rail portion mounted on a bottom surface of the upper plate, And the other end of the connecting rod is connected to at least one of the connecting member and the lower plate to adjust a descending speed or a height of the upper plate.
Here, one end of the connecting rod is coupled to a rail bracket, and the rail bracket can move along the rail through engagement of a lock lever and a nut received in the rail.
The rail bracket further includes at least one friction lever, a friction lever elastic member, and a friction lever nut for adjusting a speed at which the rail bracket frictionally moves with respect to the rail, and a friction lever washer is provided between the friction lever and the friction lever nut .
Further, the rail bracket has at least one protrusion, and a stopper having at least one stopper groove formed along the rail direction is provided on the bottom surface of the upper plate, so that the height of the top plate can be adjusted by selectively fastening the protrusion to the stopper groove. have.
One end of the stopper is fixed by a hinge and the other end is rotated in a left-right direction to selectively fasten the stopper groove and the protrusion. The other end of the stopper is connected to an elastic member so that the protrusion and the stopper groove are closely contacted to each other have.
The height adjustable desk according to the present invention can improve safety and ease of use by using an improved additional structure, and can be applied to an existing desk, thereby providing economical superiority.
