Description

{ANGLE CONTROL APPARATUS FOR LAMPSHADE SUPPORT}

More particularly, the first fixing member is fixed to the fixture and the second fixing member is fixed to the lamp shade so that the angle of the support from the fixture is adjusted and the angle of the lamp shade To an angle adjusting device for a lamp shade support to adjust the angle.

In Korea Utility Model Publication Bulletin (1988-0001533 publication date: 1988. 04. 21), the joint part of the support is composed of a frictional joint of a simple structure, and the electric part which can easily fix the back position without using the tension spring A stand has been proposed.

In the above-described conventional electric stand, holes are formed at both ends of a conventional square having a square cross section, and semicircular protrusions are formed at the corners of the steel sheet facing each other on the outside of the hole, And the semi-circular protrusions are fastened in the respective holes by inserting the screws from one side of the through hole and filling the other side with the handle-shaped nuts.

However, if the knob-type nut is tightened in the joint portions of the conventional electric stand as described above, there is a risk of breakage of both steel plates because the middle portions of both steel plates are bent inward. As a result, frictional force is generated There is a problem that the frictional action is reduced and the angle can not be maintained at a constant angle by repeating the lifting or lowering of the support for a long period of time in order to vary the position of the support. When the respective pillars are rotated around the semicircular protrusions, the pairs of pillars are brought into contact with each other and the pivot angle is narrowed.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and a method for controlling the angle of a user, And the angle of the lamp shade is adjusted so that it can be used for a long time without any trouble.
