Summary:11 HEIGHT ADJUSTMENT APPARATUS A ratchet-type catch assembly is disclosed for attachment as a slide connection between a scissors frame and an object supported by the frame. While one leg of the scissors frame is fixed to the object in a hinge-type, nonsliding manner and the other in sliding manner, the assembly forms part of the latter, providing a series of locking catches at successively varying angles of the scissors frame, and the discrete graduated heights of the object. The pawl and ratchet stops are oriented to permit vertical elongation of the frame by the application of upward force to the object, while preventing collapse. The catch is opened by release of the pawl, permitting complete collapse of the frame to a flattened configuration.
