ABSTRACT:
An adjustable height table comprising a telescoping table support assembly including stationary and movable posts interconnected in telescoping relationship to one another and positionable by a drive screw and a captive nut. The screw is mounted for rotation about its own axis, and is secured against translation along its axis, relative to one of the posts (preferably, the fixed post) such that its axis of rotation is roughly parallel the direction of the telescoping motion between the two posts. The nut is secured against rotation as the screw is rotated. The nut is provided with a female connection dimensioned to loosely captivate a pin secured to the other post (e.g., in the preferred embodiment, the movable post) so as to be roughly normal to the axis of rotation of the screw. Preferably, the bearing surface between the nut and the pin is minimized and restricted to a region of the nut proximate the surface of the screw.
