Abstract: A bed (10) includes a base (12) and a frame assembly (14). A head end support assembly (16) and a foot end support assembly (18) are coupled between the base (12) and the frame assembly (14). The frame assembly (14) includes first and second side frame members (80, 82) located above the base (12). The bed (10) also includes a plurality of latch mechanisms (160) coupled to the first and second side frame members (80, 82), and a patient support surface (162) configured to be coupled to the first and second side frame members (80, 82) by the plurality of latch mechanisms (160). A rotational drive mechanism (130) is coupled to the foot end support assembly (18) to rotate the frame assembly (14) about its longitudinal axis to a prone position. A proning surface (250) is coupled to the frame assembly (14) to support a patient in the prone position.

Abstract: A pilot operated check valve is configured to be positioned inside a fluid supply tube connected between an air supply manifold and an air zone located on a support surface of abed. The pilot operated check valve includes a body having an air inlet and an air outlet connected by an air passageway. The pilot operated check valve also includes a valve member configured to move between an open position and a closed position to block air flow through the passageway. Additionally, the pilot operated check valve includes a push rod having a first end coupled to the valve member to unseat the valve member when the valve member is in its open position and a second end. The pilot operated check valve includes a diaphragm located in a chamber of the body adjacent the second end of the push rod. The pilot operated check valve further includes an inlet port configured to be coupled to the manifold to admit pressure against the diaphragm.

Abstract: A castor locking apparatus for a castor assembly rotatably mounted to the frame member of a fluidized bed by a support that includes a notched portion. The locking apparatus includes a housing coupled to the castor with the housing including an interior region with a top opening located adjacent to the notched portion of the frame and first and second notched portions spaced apart from the top opening. Each of the first and second notched portions of the housing are spaced from the opening a distance corresponding to each notched portion, with the second notched portion being closer to the housing opening than the first notched portion. A spring loaded locking pin is located within the housing and is biased upwardly by the spring such that the pin engages the notched portion of the frame to prevent rotation of the castor assembly relative to the frame.

Abstract: A diffuser assembly is configured to support a fluidizable medium on a fluidized bed. The diffuser assembly includes a diffuser board which is permeable to air and impermeable to the fluidizable medium, and a metal plate coupled to the diffuser board. The metal plate is formed to include a plurality of apertures therein to permit air to pass through the metal plate. The metal plate has an outer perimeter edge. The plurality of apertures are spaced inwardly from the outer perimeter edge of the metal plate by a predetermined distance to define a solid border configured to block air flow through the metal plate adjacent the outer perimeter edge.

Abstract: An industrial truck has a hydraulic fluid supply and at least one double-acting hydraulic cylinder assembly for moving a movable element of the vehicle. The cylinder assembly includes a cylinder having a fluid chamber therein, and a piston movable axially in the cylinder. An actuator rod extends from the piston for connection to the movable element. The piston divides the fluid chamber into a rod end chamber and a piston end chamber each having hydraulic fluid therein. A pair of two-way two-position poppet valves are selectively actuatable between a first joint state in which both of the valves are in a normally closed position in which the piston does not move; a second joint state in which a first one of the valves is closed and a second one of the valves is open to move the piston in a first direction; and a third joint state in which the first one of the valves is open and the second one of the valves is closed to move the piston in a second direction opposite to the first direction.
