Abstract
A patient support has caster devices supporting a frame for movement in relation to a supporting surface. A lift supports an auxiliary wheel in relation to the frame. A shaft may be rotatable to drive the lift to move the auxiliary wheel between a deployed position and a retracted position. The shaft may rotate to control deployment and retraction of the auxiliary wheel. A sensor may control deployment and retraction of the auxiliary wheel. An element may provide a dampening effect when the auxiliary wheel encounters a raised surface and urge the auxiliary wheel into contact with the supporting surface when the auxiliary wheel encounters a lowered surface.
Claims12
A patient support comprising:
- a frame,
- a plurality of caster devices supporting the frame for movement in relation to a supporting surface,
- an auxiliary wheel,
- a lift supported in relation to the frame, the auxiliary wheel supported for movement in relation to the lift about an axis of rotation within an area bound by the caster devices,
- a shaft rotatable about an axis of rotation to drive the lift to move the auxiliary wheel in relation to the frame between a deployed position contacting the supporting surface and a retracted position spaced from the supporting surface, and
- a device configured one or more shaft rotations to control deployment and retraction of the auxiliary wheel by the lift.
A patient support comprising:
- a frame,
- a plurality of caster devices supporting the frame for movement in relation to a supporting surface,
- an auxiliary wheel,
- a motor operably connected to the auxiliary wheel for rotating the auxiliary wheel,
- a lift supported in relation to the frame and supporting the auxiliary wheel for movement about an axis of rotation within an area bound by the caster devices,
- an actuator configured to drive the lift to move the auxiliary wheel in relation to the frame between a deployed position contacting the supporting surface and a retracted position spaced from the supporting surface,
- a sensor arranged and configured to control deployment and retraction of the auxiliary wheel by the lift,
- an element configured to provide a dampening effect when the auxiliary wheel encounters a raised surface of the supporting surface and urge the auxiliary wheel into contact with the supporting surface when the auxiliary wheel encounters a lowered surface of the supporting surface, and
- at least one push handle operable to control the motor, the push handle being movable in a first direction to control the motor to rotate the auxiliary wheel in a first direction and in a second direction to control the motor to rotate the auxiliary wheel in a second direction.
A patient support comprising:
- a frame,
- a plurality of caster devices supporting the frame for movement in relation to a supporting surface,
- an auxiliary wheel,
- a lift supported in relation to the frame and supporting the auxiliary wheel for movement about an axis of rotation within an area bound by the caster devices,
- an actuator configured to drive the lift to move the auxiliary wheel in relation to the frame between a deployed position contacting the supporting surface and a retracted position spaced from the supporting surface,
- a sensor arranged and configured to control deployment and retraction of the auxiliary wheel by the lift,
- an element configured to provide a dampening effect when the auxiliary wheel encounters a raised surface of the supporting surface and urge the auxiliary wheel into contact with the supporting surface when the auxiliary wheel encounters a lowered surface of the supporting surface, and
- a control panel including one or more buttons selected from a group of buttons for activating the control panel, increasing the speed of the drive motor, and decreasing the speed of the drive motor.
