Abstract
A height-adjustable table can include a frame supporting a work surface; a pair of lower legs supporting the frame; a pulley mechanism coupling the frame and the pair of lower legs for vertically moving the frame relative to the pair of lower legs; and a spring located within a passage extending through the frame. The spring may have 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 can have a block-and-tackle assembly located within the passage and coupling the movable end of the spring to the pulley mechanism. The block-and-tackle assembly can transfer the force exerted by the spring over the first distance to vertical movement of the frame relative to the pair of lower legs over a second distance greater than the first distance.
