PROBLEM TO BE SOLVED: To provide a lifting mechanism for performing continuous erecting operation and inclining operation without reattaching a shaft serving as the center of performing the erecting operation of a link.SOLUTION: The lifting mechanism includes: a first circular arc part C1 for guiding a second regulation part 43 so as to move on a circular arc with a first regulation part 33 as the center a second circular arc part C2 for guiding the second regulation part 43 so as to move on a circular arc with a turning shaft 31 as the center and a third circular arc part C3 for guiding the first regulation part 33 so as to move on the circular arc with the turning shaft 31 as the center. The first circular arc part C1 and the second circular arc part C2 are continuously provided. When a driven member 6 is moved from an initial position to a prescribed height, the first regulation part 33 is not moved relative to a second link 4 and the second regulation part 43 moves the first circular arc part C1. When the driven member 6 is rotated from a rotation initial position to a prescribed angle, the first regulation part 33 moves the third circular arc part C3 and the second regulation part 43 moves the second circular arc part C2.COPYRIGHT: (C)2013,JPO&INPIT【課題】リンクの起立動作をする中心となる軸を付け替えることなく連続した起立動作と傾斜動作をする昇降機構を提供することを目的とする。【解決手段】第一規制部33を中心とした円弧上を移動できるように第二規制部43をガイドする第一円弧部C1と、回動軸31を中心とした円弧上を移動できるように第二規制部43をガイドする第二円弧部C2と、回動軸31を中心とした円弧上を移動できるように第一規制部33をガイドする第三円弧部C3とを備え、第一円弧部C1と第二円弧部C2は連続して設けられ、従動部材6が初期位置から所定の高さまで移動する際に、第一規制部33は前記第二リンク4に対して相対移動せずに、第二規制部43が第一円弧部C1を移動し、従動部材6が回転初期位置から所定の角度まで回転動作をする際に、第一規制部33が第三円弧部C3を移動すると共に、第二規制部43が第二円弧部C2を移動するようにする。【選択図】図1
