Abstract
A power drive for a patient support apparatus comprises a wheel support, a powered wheel, and a deployment actuator. The wheel support is configured to be pivotably coupled to a frame member of the patient support apparatus. The wheel support includes a mechanical stop engageable with another portion of the power drive when the wheel support is in a retracted position.
Claims20
A power drive for a patient support apparatus comprising:
- a wheel support configured to be pivotably coupled to a frame member of the patient support apparatus, the wheel support including a mechanical stop engageable with another portion of the power drive when the wheel support is in a retracted position;
- a powered wheel supported on the wheel support, the powered wheel configured to, when engaged with a floor, rotate under power to move the patient support apparatus across the floor;
- and
- a deployment actuator operable to cause the wheel support to pivot relative to the floor to move the powered wheel into and out of engagement with the floor, the deployment actuator configured to cause the mechanical stop to engage the portion of the power drive when the deployment actuator is in a fully retracted position, the stop operable to prevent a force from being imparted to the deployment actuator when the wheel support engages an obstruction in the floor.

A patient support apparatus comprising:
- a base frame supported on casters for moving the patient support apparatus over a floor;
- a wheel support pivotably coupled to the base frame, the wheel support including a mechanical stop;
- a powered wheel supported on the wheel support, the powered wheel configured to, when engaged with a floor, provide motion to move the patient support apparatus over the floor;
- and
- a deployment actuator operable to cause the wheel support to pivot relative to the floor to move the powered wheel into and out of engagement with the floor, the deployment actuator configured to cause the mechanical stop to engage to prevent a force from being imparted to the deployment actuator when the deployment actuator is retracted.
