Scissors lift table

A scissors lift table comprising a lift platform, a scissors mechanism for raising said platform above and for lowering said platform onto a base frame in a vertical direction, said scissors mechanism comprising at least two laterally adjacent scissors arm pairs, each comprising two scissors arms mutually pivotably coupled in their median region and pivotable relative to each other, drive means for pivoting said arms, one end of each arm of each arm pair being mounted stationarily but rotatably on the lift platform or the base frame respectively and the other end of each arm of each pair being slidably guided in the base frame or the lift platform respectively, said drive means comprising an elongate cylindrical roller adapted to be motor-driven in rotation, which is mounted stationarily relative to the base frame and has an indexing groove provided in its cylindrical surface as a driving member, an indexing pin which engages in the groove and is arranged on a driven member forming an elongate carriage which is guided for longitudinal sliding movement, the carriage carrying a rack which meshes with a first toothed pinion which is operatively coupled with a second toothed pinion which meshes with a toothed segment on one of the scissors arms, the center of the pitch circle radius of the toothed segment coinciding with the stationary pivot point of said scissors arm on the base frame.
