ABSTRACT:
The present invention provides a lift used for automobile maintenance, which has a novel link mechanism consisting of a smaller number of parts required to have significantly high precision, and is manufactured at a relatively low cost. The lift allows a mechanic to check and repair a lower portion of a vehicle in a standing attitude. The link mechanism of the invention has a smaller number of joints, thus effectively preventing excessive looseness of the lift even after long-term use. The lift of the invention includes a pair of base elements placed in a pair of pits, a pair of tables for supporting a lower body frame of a vehicle other than four wheels, and a pair of link mechanisms where a long arm crosses and is fixed to a short arm at a position in the middle of the long arm via a center shaft. Each short arm is integrally fixed at a first end thereof to a connection shaft, which is rotatably attached to one side of the base elements. Each long arm has a first end pivotably attached to the table and a second end with a roller slidably movable along a pair of curved rails formed on the base element. In response to the sliding movement of the second end of the long arm along the pair of curved rails, the table descends to a lower most position or ascends to an upper most position. The link mechanism further includes a push rod for joining a second end of the short arm with the table.
