Overhead bunk linkage

Abstract

Abstract THE OVERHEAD BUNK LINKAGE FOR POSITIONING AND SUPPORTING ASSISTS IN MANIPULATING A LOAD SUCH AS A BUNK BED BETWEEN STORAGE AND USE POSITIONS, SPACED LINKAGE ASSEMBLIES ARE LOCATED ON ADJACENT EACH END OF THE BUNK DESIGNED TO OPERATE IN SPACED PLANAR REGIONS PERPENDICULAR TO THE BUNK. EACH LINKAGE ASSEMBLY HAS FRONT AND REAR DOWNWARDLY EXTENDING SUPPORT LINKS, EACH LINK MOUNTED FOR SWINGING MOVEMENT FROM AN UPPER SUPPORT REGION WHERE SPRING MEANS ARE PROVIDED TO URGE THE LOWER ENDS OF THE FRONT THE REAR LINKS TOWARD EACH OTHER, ADJACENT THE LOWER ENDS OF THE LINKS, TRACKS ARE PROVIDED ON THE ENDS OF THE BUNK EXTENDING ADJACENT THE PLANE OF THE SWING OF THE LINKS WITH A SLIDING CONNECTION BETWEEN THE LINKS AND THE TRACKS. THE TRACKS EXTEND FRONT AND REAR FROM THE CENTRAL REGION OF THE BUNK AND PREFERABLY ARE INCLINED UPWARD IN THEIR PATH TOWARD FRONT AND REAR. WITH THIS SLIDING CONNECTION AND A SUBSTANTIAL SWINGING FORCE ON THE LINKS, THE DIRECTION OF MOVEMENT OF THE LINKS RELATIVE TO THE INCLINED TRACKS EXERTS COMPONENTS OF LIFTING FORCE UPWARD ON THE BANK THUS TO ASSIST MANUAL MANIPULATION OF THE BUNK TOWARD AND AWAY FROM A STORAGE POSITION.
