Description

[0001] Appartus for Controlling the Inclination of Desk [0002]

The present invention relates to an apparatus for adjusting the inclination angle of a desk, which is applied to various desks used in general homes, offices, and industrial fields, and more particularly to an apparatus for adjusting the inclination angle of a desk, The present invention relates to a desk angle adjusting apparatus capable of easily and precisely adjusting the angle of a desk top plate to a desired angle so that the angle can be easily and precisely adjusted.

In general, desks have been developed to adjust the inclination angle of the desk top plate to facilitate work on the desk, examples of which are shown in the following patent documents.

Patent Document 1 relates to an angle adjustable table. In view of the structure and function, a table is connected to an outer frame by a hinge, and a support bar is coupled to a table by a support bar bracket so that the end of the support bar is inclined with respect to the angle adjusting bracket And the inclination angle of the table is maintained.

However, in the angle-adjustable table of Patent Document 1, when the angle of the table is adjusted by the users, the support rods must be inserted and fixed in accordance with the acute or obtuse angular grooves of the angle adjusting bracket, so the adjustment of the inclination angle of the table is very cumbersome and inconvenient. In particular, when the weight of the top plate of the table is excessively large, or when the angle is adjusted with heavy objects placed on the table top plate, there is a disadvantage that excessive force is applied to the users. Moreover, when the angle of the top plate is adjusted, There is also a possibility of a safety accident if the top plate is missed because it is not successful.

The improvement and development of this point is a 'desk having a top plate capable of adjusting the angle' of Patent Document 2.

The desk is constructed such that the upper plate is hinged to any one of the body and the angle is adjusted by providing an angle adjusting means on the bottom surface so that the upper plate is lifted forward about the hinge and the angle is adjusted, The rear arm of the upper plate is lifted up around the hinge to adjust the angle by means of an arm rotating with a forward motor and the upper plate of the desk can be angularly adjusted in a multi- So that the rear of the upper plate is lifted forward.

However, since the desk having such a structure requires a forward motor and a worm gear to be installed, a space for a separate forward and reverse motor is required. This increases the volume of the desk and increases the complexity of the desk structure In particular, there is a concern that a separate electric supply facility must always be provided for driving the forward and reverse motors, and there is a risk of fire due to the problem of the electric short-circuit, which may result in poor practicality and economical efficiency.

Accordingly, it is urgently required to develop a desk inclination angle adjusting apparatus which can easily adjust the inclination angle of the desk top plate while preventing the risk of safety accident even with the weight of the top plate.
