Abstract
Abstract A bed structure is disclosed for providing a sleeping platform, e.g. by supporting a mattress and springs, that may be raised from a conventional residual position and concurrently displaced from a headboard to a convenient position for making up the bed. A plurality of pivotally-mounted links are affixed between a bed frame and a holder for the springs or the like. The pivotal links are interconnected by a crank mechanism extending between individual pairs of links and connected by coil springs to the bed frame so that the bed is urged to an elevated or convenience position. A locking mechanism is incorporated for fixing the structure in a lower reclining position, as while using the bed.
