The invention provides a powered retraction system for a wheel. The retraction system includes an actuation system to raise the wheel to a stowed position and to lower the wheel to a steer position. The actuation system includes: a motor that is operably connected to a rotatable torsion controller to rotationally drive the torsion controller about a torsion controller axis; a torsion element comprising opposing first and second ends; and a swing arm operably connected to the wheel axle and rotatable by the torsion controller about a swing arm axis to raise and lower the wheel. The first end of the torsion element engages with the rotatable torsion controller and the second end of the torsion element engages with the swing arm. When in the steer position, the torsion element is tensioned to urge the spring arm, and in turn the wheel, downwards.

The invention provides a powered drive wheel assembly for a wheeled apparatus, such as a hospital bed, a nursing care bed, or a stretcher. The assembly is attachable to a chassis of the wheeled apparatus and comprises a powered drive wheel rotatably mounted on a wheel axle and a traction enhancing suspension system comprising: a swing arm rotatably attached to the wheel axle at or near a distal end of the swing arm and also rotatably attached to a mounting feature at or near a proximal end of the swing arm, the mounting feature being directly or indirectly attachable to a chassis of the wheeled apparatus; and a biasing member to bias the distal end of the swing arm downwardly to apply a downward force on the wheel axle; a first connecting member rotatably attached to the mounting feature; and a second connecting member, wherein the second connecting member is movably attached to the first connecting member and fixedly attached to the wheel axle.
The invention provides a castor control system for a wheeled apparatus having a chassis with a plurality of castors adapted to operate in at least two different operating modes, including a brake mode. The castor control system includes: a rotatable toggle that is operably engageable with a rotatable driven element driven by a motor to enable the toggle to rotate between at least two different positions by operation of the motor, and a transmission system comprising a transmission link, a first control element, and a first transmission lever. The driven element is rotatable by the motor in a first direction to cause the toggle and the driven element to rotate to a first position, and the driven element is also rotatable by the motor in a second direction, opposite to the first direction, to adopt a neutral position after the toggle reaches the first position. The toggle is rotatably connected to the transmission link, to move the transmission link in opposing first and second directions upon rotation of the toggle by operation of the motor. The transmission link is operably connected to a first control element that engages with at least one castor and comprises a major axis about which the control element is rotatable. At least one pedal is fixedly connected to the control element and is rotatable between positions corresponding to the different operating modes of the castors. When the driven element is in the neutral position, manual operation of the pedal causes rotation of the toggle without engaging the motor.

The actuation system includes: a motor that is operably connected to a rotatable torsion controller to rotationally drive the torsion controller about a torsion controller axis; a torsion element comprising opposing first and second ends; and a swing arm operably connected to the wheel axle and rotatable by the torsion controller about a swing arm axis to raise and lower the wheel. The first end of the torsion element engages with the rotatable torsion controller and the second end of the torsion element engages with the swing arm. When in the steer position, the torsion element is tensioned to urge the spring arm, and in turn the wheel, downwards.

The invention relates to a side rail for a care bed. The side rail may comprise an electronic user interface located on an interface support that is able to attach to and detach from the side rail. The user interface includes one or more inputs to control operation of the bed. Optionally, the user interface is a membrane keypad and may be curved to be located on a curved edge of the side rail.
A compact, foldable side rail for a bed comprising an upper part (120) and a lower part (130) that are hinged together at a first pivot (150). The side rail is attached to a bed by a positioning system that causes the lower part of the side rail to fold toward the upper part and allows the upper part to lie in substantially the same plane as it is raised and lowered. The side rail includes a locking mechanism. The positioning mechanism comprises an upper part pivot arm (140) that attaches to the upper part via a second pivot (126) and attaches to the bed via a third pivot (127); and a lower part pivot arm (141) fixedly attached to the lower part (130) and that attaches to the bed via a fourth pivot (128).
