An apparatus for supporting a display in a plurality of positions between a lower position and an upper position has a base support, a display support member, and a linkage assembly. The linkage assembly has a first link member, a second link member, and a tension spring. In the lower position, the display bracket is below an upper end of the base support, and in the upper position, the display bracket is above the upper end of the base support. In each of the plurality of positions, a vertical component of an upward force exerted on the display support member by the linkage assembly is substantially constant.

Adjustable counterbalancing display support

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.
