Abstract:
A 90-degree-rotatable rail structure for mounting to a framed bed which has a side rail frame structure comprising: a bracket structure for mounting to one said side rail of said side rail frame structure (21) of said bed; a rail structure (41) which is secured to said bracket structure, said rail structure comprising a rigid, quadrilateral framework with a pair of parallel legs (43,44) supporting said framework, said legs being joined by a rectangular plate (49), said rectangular plate including an abutment plate (57) secured thereto; a bilobed cam disc (31) which is secured to said bracket structure and which is rotatably mounted with respect to said rectangular plate, said rail structure thereby being rotatable from a first, positively-stopped and automatically locked orientation, where the length of said rectangular framework is parallel to said side rail, and where a first lobe (35) of said bilobed cam disc abuts another face of said abutment plate to a second, positively-stopped and automatically locked orientation, where the length of said rectangular framework is perpendicular to said side rail, and where a second lobe (37) of said bilobed cam disc abuts one face of said abutment plate, and also being rotatable from said second, positively-stopped and automatically locked orientation back to said first, positively-stopped and automatically locked position; and cooperating automatically lockable means between said bilobed cam disc and said rectangular plate selectively, and automatically, to lock said rail structure in said first, positively-stopped and automatically locked, orientation or in said second, positively-stopped and automatically locked, orientation.
