ELEVATOR DEVICE AND WORKING BENCH

PURPOSE:To stabilize the rising and lowering of a movable frame by keeping the supporting point of the movable frame and an X-shaped link, in the rising and lowering by the X-shaped link. CONSTITUTION:An elevator device consists of a main link 31 which is formed by pivotally installing each top edge part of a main upper girder 11 and a main lower girder 12 in an equal length and a sublink 32 which is formed by pivotally installing a subupper girder 21 and a sublower girder 22, and the lower edge of the main lower girder 12 is pivotally installed on a fixed frame 1, and the upper edge of the main upper girder 11 is pivotally installed on a movable frame 2, and the upper and lower pivotal installation points are arranged on a vertical line, and the upper edge of the subupper girder 21 is pivotally supported at the center part of the main upper girder 11, and the lower edge of the sublower girder 22 is installed in a slidable manner. The center part in the longitudinal direction of the sublower girder 22 is pivotally supported at the center part in the longitudinal direction of the main lower girder 12, and the length between the lower edge of the sublower girder 22 and the pivotal supporting point of the main lower girder 12 the length between the pivotal supporting point for the main lower girder 12 and the pivotal supporting point for the subupper girder 21, and the length of the subupper girder 21 are set to an equql length.
