DESK PARTICULARLY FOR THE PLACE OF TREATING IMAGE SCREEN

摘要

PURPOSE: To easily adjust the height of a desk board without being affected by load every time, by selecting the curve passage of a curved rail so that a vertical power component to be exerted upon a guide rod can be almost equally sized at both the terminal positions of the desk board. CONSTITUTION: One spring end part 6 of a spring leg 5 is coupled through a joint to a guide rod 2, and another spring end part 7 is held by a fixed curved rail 8 on a desk frame 3 at a prescribed set angleα. The held spring end part 7 can be moved on the curved rail 8 by an adjuster 9 and can be locked at positions corresponding to the various loads of a desk board 1. The curve passage of the curved rail 8 is selected so that vertical power components P1 and P2 to be exerted upon the guide rod 2 can be almost equally sized not only at both the terminal positions of the desk board 1 at least but also at height positions between them.
