第１項記載のリフター。[Claims for Utility Model Registration] (1) A lifting platform that ascends and descends while maintaining a parallel state with respect to a fixed base is connected to a pair of link members via a cross link pivotally attached to the center part thereof. In the cross link, the tip of each link arm extending to one side of the pivot is pivotally connected to the base and the lifting platform, and the tip of each link arm extending to the other side is connected to the downward rail surface of the lifting platform. In a lifter configured by being pivotally connected to rolling rollers that are respectively rolled into contact with the upward rail surface of a base, opposing inner surfaces of each link arm extending on the same side of both intersecting links are each provided with a required curvature. Forming a pair of bulging arcuate guide rails,
A drive roller is provided which is individually rolled in contact with the pair of guide rails, and a common support shaft of the drive roller is provided.
It is connected to a rod of a linear drive machine installed horizontally between the pivots of both of the cross links, and each cross link is erected by the driving roller pressing the guide rail due to the shortening operation of the rod. A lifter characterized by comprising: (2) The lifter according to claim 1, wherein the curvature of each guide rail is set so that the load on the linear drive machine is constant over the entire stroke of the lifter.
