Claims

[Claims for Utility Model Registration] 1. A main body frame formed in a substantially rectangular frame shape with four pipe-shaped support rods, and four pipe-shaped support rods that are slidably inserted into the main body frame. It is equipped with an elevating frame that is equipped with a pipe-shaped support rod and is slidably attached to the main body frame in the vertical direction, and an elevating mechanism that manually raises and lowers the elevating frame, and the main frame and the elevating frame are The two pantograph arms are connected via a pair of pantograph arms that are bendable at their longitudinal centers and pivoted at their intersections, and one pantograph arm has its lower end pivoted to the lower part of the front edge of the main body frame. At the same time, its upper end portion is pivotally attached to the upper part of the front side of the elevating frame,
The other pantograph arm has its lower end attached to a movable rod that is movable back and forth along a pair of guide rails arranged on the left and right sides of the bottom of the main body frame, and its upper end attached to the left and right sides of the upper part of the elevating frame. The movable rod is attached so as to be movable in the front and back direction along a pair of guide rails arranged on the rod. is rotatably attached to a fixed rod fixed to the front lower part of the main body frame, and is formed so that the elevating frame can be moved up and down relative to the main body frame by moving the movable rod by rotating the lifting threaded rod. An elevating movable scaffold featuring: 2. The main body includes a main body frame formed in a substantially rectangular frame shape with four pipe-shaped support rods, and four pipe-like support rods that are slidably inserted into the support rods of this main body frame. It is equipped with an elevating frame that is slidably attached to the frame in the vertical direction, and an elevating mechanism that manually raises and lowers the elevating frame.The main frame and the elevating frame are bent at approximately the center in the longitudinal direction. The pantograph arms are freely movable and are connected to each other via a pair of pantograph arms which are pivotally connected at their respective intersecting parts. The upper end of the pantograph arm is pivoted to the upper part of the front side of the lift frame, and the lower end of the other pantograph arm is movable in the front and back direction via rollers along a pair of guide rails arranged on the left and right sides of the lower part of the main body frame. At the same time, the upper end portion thereof is formed to be movable in the front and back direction via a roller along a pair of guide rails arranged on the left and right sides of the upper part of the lifting frame, and a movable rod is formed at approximately the longitudinal center of the other pantograph arm. , a hydraulic jack is interposed between the movable rod and the fixed rod, and the elevating frame is formed so that it can be raised and lowered with respect to the main body frame by movement of the movable rod by the operation of the hydraulic jack. Mobile scaffolding.
