RATTLING PROTECTIVE STRUCTURE FOR ELEVATION LEG PART IN BED PROVIDED WITH FLOOR ELEVATION MECHANISM

摘要

PROBLEM TO BE SOLVED: To restrict rattling of a movable part in a floor part elevation mechanism, and to smooth elevation action.;SOLUTION: An inner support part 13, and an outer support part 14 installed on the inner support part 13 to be movable to advance/retract by an elevation mechanism are provided, and between the outer support part 14 and the inner support part 13, a fixed spacer to maintain a gap G, and an adjusting spacer 16 to adjust the gap G are disposed to diagonally face each other. The adjusting spacer 16 is disposed to be diagonally applied to a corner part inside the outer support part 14 through a cut in the inner support part 13, a stepped eccentric screw 23 is inserted into a through hole 22 formed deflected from a center position, and it is tigtened to a fixing metal by an adjusting nut 24, thereby a chamfered end surface of the adjusting spacer 16 is pressed to an inner wall surface of the outer support part 14 perpendicular to it.;COPYRIGHT: (C)2000,JPO
