ABSTRACT:
An extendable table of the disclosure includes an extendable frame having laterally spaced slide assemblies extending between opposite ends thereof so as to be capable of supporting table tops of different lengths. Each slide assembly includes a pair of elongated hollow female beams projecting from opposite ends of the frame and having open ends that receive the opposite ends of an elongated male support member which aligns and slidably interconnects the beams with each other in cooperation with an improved pad arrangement. The pad arrangement permits the support member and beams to have their elongated axes unaligned as the support member is inserted into the beams and the support member is maintained within the beams by a snap action locking that secures certain pads of the arrangement to the open ends of the beams. The support member is positioned in a spaced relationship with respect to the cross-sections of the beams to permit sliding movement therebetween despite variance in the size of these components along their axial lengths.
