ABSTRACT:
A height adjustable table adapted for wheelchair use includes a top member and depending end panels defining channel structure for telescopingly receiving leg structures at the ends of the top member. An actuator includes an extendable and retractable rod which is connected to the leg structures by flexible cables which are reeved over pulleys. Extension and retraction of the rod results in raising and lowering of the top member and end panels with respect to the leg structures. Readily accessible hand controls are positioned for easy access by the user for raising and lowering the top member. An adjustable control automatically limits the maximum height of the top surface with respect to the leg structures.
