More Information
Summary:A mechanism for raising and lowering the height of a patient support surface of a bed (10) which includes a threaded shaft (68) upon which a pulley support (96) is raised and lowered and a chain (86) and pulley system which transfers vertical displacement of the pulley support (96) to the patient support surface. An articulating perimeter frame (34) for supporting a patient on a bed frame which includes a plurality of extruded elongate members (230) which are coupled together by hinges (132, 246) and corner members (240). The perimeter frame (34) receives and supports inserts (260, 262, 264) which receive head (48), seat (50) and foot (52) mattress sections. A pivotal push handle/tray combination (26) that is pivotally coupled to the end posts (77) of a bed and includes a mechanism for locking the handle/tray combination (26) into one of a plurality of positions. Cette invention concerne un mécanisme permettant de faire monter et descendre la surface porteuse d'un lit de patient (10) qui comprend un axe fileté (68) sur lequel monte et descend, un ensemble à chaîne (86) et poulies qui permet de transférer à la surface porteuse du patient le déplacement vertical du palan (96). L'invention concerne également un cadre périphérique articulé (34) permettant de porter un patient sur un cadre de lit et qui comprend une pluralité de parties extrudées et allongées (230) reliées par des charnières (132, 246) et des raccords en coin (240). Le cadre périphérique (34) reçoit et porte des raccords (260, 262, 264), lesquels reçoivent les parties tête (48), siège (50) et pied (52) du matelas. L'invention concerne enfin un ensemble pivotant plateau/poignée poussette (26) couplé pivotant aux montants (77) du lit et qui comprend un mécanisme permettant de bloquer dans l'une de la pluralité de positions l'ensemble plateau/poignée (26).
