PURPOSE: To provide a lever-type automatic article lifting device, which is downsized and which can easily lift up a heavy article with the small force even in a narrow place with the simple operation, by integrally combining the work of gear as combination of gears, the work of screw and the work of lever, and electrically moving it with a motor.
CONSTITUTION: A strong base is provided with a base support A. A supporting point base 22 is installed on a lever base, and when a supporting point shaft 3, which is supported by a supporting point holder 4 unified with a shaft 5 of the lever, is installed in the supporting point base 2, the shaft 5 of the lever can be turned around the supporting point shaft 3 as a supporting point, and a lever is thereby formed. A screw is formed of a screw bar 7 and a moving piece 8, which are installed in the same base. The shaft of the lever is held by lever holders 9-1, 9-2, which moves integrally with the moving piece 8, and the lever and the screw are connected to each other. A gear is formed of a gear 10 and a gear 11, and the gear 10 is fitted to the screw bar 7 so as to connect the gear to the screw. The gear 11 and a motor 12 are connected to each other so as to connect the gear and the motor. The motor 12 is controlled by a movable operation box 19, and the lever-type automatic article lifting device is formed with this structure.
