Abstract

A height-adjustable table includes a frame supporting a work surface; a pair of lower legs supporting the frame; a pulley mechanism coupling the frame and the lower legs for vertically moving the frame relative to the lower legs; and a spring located within a passage extending through the frame. The spring has a fixed end secured to the frame and a movable end movable relative to the frame over a first distance for exerting a force over the first distance. The table further includes a block-and-tackle assembly located within the passage. The block-and-tackle assembly couples the movable end of the spring to the pulley mechanism for transferring the force exerted by the spring over the first distance to vertical movement of the frame relative to the lower legs over a second distance greater than the first distance.
