Mattress transport mechanism

摘要

A transport mechanism for supporting and laterally moving a bed mattress over the bed frame. The bed frame is divided between a longitudinally extending central frame and a longitudinally extending lateral frame pivoted thereto. Chain drives mounted in the head and foot of the central and lateral frames are attached to the head and foot ends of a flexible mattress support. The lateral frame is pivotal to cause the courses of the chains over the lateral frame to form variably adjustable angles with the courses thereof over the central frame.
