ABSTRACT:
A height adjustable chair arm assembly includes an inner tube joined to an arm support of a chair, an elongated lock plate disposed within the inner tube and a lock tube assembly including an upper lock release housing and an elongated guide tube telescopingly disposed within the inner tube. The elongated lock plate defines a plurality of vertically spaced sockets or lock indentations. An elongated lock rod is movably disposed within the lock tube. A ball lock element, disposed within the lock tube, is engaged by the lock rod. The rod is movable from a locked position wherein the rod holds the lock element within one of the indentations and an unlocked position wherein the lock element may move out of the indentation and the lock tube assembly may telescope with respect to the inner tube. An armrest or arm cap is fixed to an upper end of the lock tube assembly.
