Abstract

A bed comprises a deck section having a width and left and right outboard deck edges. Left side and right side wings are movably coupled to the deck section. The bed also includes a left leadscrew receiver mounted on the left wing, a right leadscrew receiver mounted on the right wing, and left and right motor assemblies both mounted on the deck section. A left leadscrew is coupled to the left motor assembly and to the left leadscrew receiver. A right leadscrew is coupled to the right motor assembly and to the right leadscrew receiver. Motor operation is capable of moving the wing to which it is coupled between a deployed position in which the lateral extremity of the wing is outboard of the respective outboard edge of the deck section and a stored position in which the lateral extremity of the wing is inboard of its deployed position.
