Hospital bed

Abstract

Abstract A HOSPITAL BED HAVING A SUPPORTING BASE FRAME AND AND UPPER FRAME WHICH IS VERTICALLY MOVABLE RELATIVE TO THE BASE FRAME BY MEANS OF MOTOR-ACTUATED LINKAGE. THE LINKAGE CONSISTS OF TWO SETS OF LINKS, EACH OF WHICH MAY BE SEPARATELY ACTUATED TO RAISE OR LOWER THE CORRESPONDING END OF THE UPPER FRAME, OR BOTH OF WHICH CAN BE SIMULTANEOUSLY ACTUATED TO RAISE THE ENTIRE UPPER FRAME AT ONE TIME. THE UPPER FRAME SUPPORTS A BED-SPRING ASSEMBLY INCLUDING A HEAD SECTION, A SEAT SECTION, A KNEE SECTION AND A FOOT SECTION, THE HEAD AND KNEE SECTIONS BEING PIVOTALLY CONNECTED TO THE STATIONERY SEAT SECTION, AND THE FOOT SECTION BEING PIVOTALLY CONNECTED TO KNEE KNEE SECTION. THE HEAD AND KNEE SECTIONS MAY BE SEPARATELY RAISED OR LOWERED INTO AND OUT OF INCLINED POSITIONS. THE HEAD SECTION IS ALSO PROVIDED WITH MEANS FOR DETACHABLY CONNECTING IT TO A SLIDE ON THE UPPER FRAME. WHEN THE HEAD SECTION IS ATTACHED TO THE SLIDE, IF THE HEAD SECTION IS PIVOTED UPWARDLY, IT MOVES THE ENTIRE BED-SPRING ASSEMBLY TOWARD THE FRONT OF THE BED, AND WHEN IT IS LOWERED, IT MOVES THE ENTIRE BED-SPRING ASSEMBLY TOWARD THE FOOT OF THE BED. WHEN THE HEAD SECTION IS DETACHED FROM THE SLIDE, IT PIVOTS UP AND DOWN WITHOUT AFFECTING THE HORIZONTAL POSITION OF THE BED-SPRING ASSEMBLY.
