An extendable support system having a plurality of support members and a plurality of pairs of spaced-apart side rails, each pair of which being affixed to one support member. Each of the support members move longitudinally relative to the other and include stop tabs which are configured to limit the longitudinal extension of the support system. The support members are L-shaped to add strength to the system as well as limit longitudinal retraction of the system. The extendable support system is attached to a platform by means of a pair of spaced-apart T-rails and includes extension means for increasing the angle of motion of a pivotal platform.

[ We claim:] [1.] An extendable support system, comprising:a plurality of support members, each said support member configured to move longitudinally and including a reinforcing member which provides said support members with a substantially L-shaped configuration, said reinforcing member extending substantially the width of each said support member and operating to limit longitudinal retraction of the extendable support system;a plurality of stop tabs configured to limit longitudinal extension of the support system; anda plurality of pairs of spaced-apart side rails, each pair of side rails being affixed to one support member and being arranged adjacent another pair of side rails;wherein at least one said stop tab extending from an underside of one said support member, and at least one said stop tab extending from an upperside of an adjacent support member, said stop tabs configured to engage one another to limit the longitudinal extension of said extendable support system.
