Foldable desk

Abstract

The invention provides a folding-type desk, on an upper end of left and right supporters, brackets, which are connectively mounted on two sides of a lower surface of a top plate in a manner of rotating upwards and downwards, maintains the top plate in a horizontal using gesture and a folding gesture, wherein lower limb space can be expanded, intensity of the supporters are increased, and rotational operation of the top plate can be smoothly performed, in addition, when the top plate changes the using gesture to the folding gesture, the brake can be applied to the top plate to prevent rapid rising of the top plate. A circular bearing hole (31) is formed on a side plate at outside of the bracket, and an opening (32) is formed on a side plate at inside such that the end of a connection pipe (9) is located within the bracket from the opening to form a shaft section (38) on a horizontal section (37), the shaft section (38) is rotatably tabled on a sliding ring (34) mounted on the bearing hole and enables the front end to be located within the bracket, the horizontal section and the connection pipe of the supporter connection component are interconnected in a non-rotating manner within the bracket.

Description

technical field [0001] The present invention relates to a folding table, and more specifically relates to a top plate that can maintain a substantially horizontal use posture and a folded posture that can be turned upward to stand upright, and a backboard provided under the rear portion of the top board moves in conjunction with the movement of the top board. Folding table. Background technique [0002] Conventionally, various folding tables have been provided in which the upper ends of the left and right legs are vertically rotatably connected to both sides of the lower surface of the top plate, and the top plate is fixed in a substantially horizontal use posture and an upwardly folded folding posture. It is also known to connect a bracket mounted on both sides of the top plate to the upper end of the leg body so as to be rotatable up and down, and to provide a locking mechanism in the bracket to maintain the top plate in the use position and the folded position.

AI Technical Summary

Problems solved by technology

In order to prevent this problem, there are also structures that implement countermeasures such as installing soft cushioning materials on the back plate or the leg body, but the generation of impact noise due to impact or vibration of the back plate cannot be completely suppressed.

In addition, there is also a structure in which the lateral width of the above-mentioned back plate is set to be narrower than that between the left and right leg bodies. In this case, although the back plate does not collide with the leg bodies, the link member may not collide with the back plate or the leg bodies. Collision still cannot prevent the generation of collision sound, and when multiple folding tables are arranged side by side, there will be a large gap between the adjacent backboards, resulting in the deterioration of the original function of the backboards to block the line of sight

In addition, in the folding table described in Patent Document 6, since an oil buffer is provided on the rotation shaft of the top plate, there is resistance to the rotation of the top plate in one side direction, so that the sudden lifting of the top plate and the back plate and the legs cannot be prevented. body collision, and because the buffer itself is expensive, the cost becomes high
