DISTORTION ADJUSTING MECHANISM FOR FRAME BODY, AND FRAME BODY SUITABLE FOR HOLDING LED MODULE

摘要

PROBLEM TO BE SOLVED: To provide a distortion adjusting mechanism for frame body adjustable in a distortion of a frame body caused by expansion and contraction of a supported member even if the member supported by the frame body expands and contracts by temperature change from season to season.;SOLUTION: The distortion adjusting mechanism for frame body 1 is formed as a mechanism which is arranged at corners 51, 52, 53, 54 of the frame body 50 and absorbs deformation of the frame body. The distortion adjusting mechanism for frame body 1 includes: an L-shaped channel 21 leading to movability of the frame body; compression coil springs 31, 32 arranged on both ends of the L-shaped channel with one end hooked on the end of the L-shaped channel and with another end hooked by an end of hooking pieces 41, 42; and the hooking pieces 41, 42 hooking another end of the compression coil springs 31, 32 and fixed to the frame body 50.;COPYRIGHT: (C)2011,JPO&INPIT
