Abstract
A caster apparatus is provided for a patient support. The caster apparatus includes a braking system.
Claims17
A patient support apparatus comprising:
- a patient support surface;
- a frame coupled to the patient support surface;
- and
- a caster apparatus coupled to the frame, the caster apparatus including a wheel and a brake system including an actuator, a cable, and a brake member, the cable having a first end portion coupled to the actuator and a second end portion coupled to the brake member, actuation of the cable by the actuator causing the brake member to rotate about an axis to brake the wheel, the brake member rotating about an axis of rotation that is parallel to an axis of rotation for the wheel.

A patient support apparatus comprising:
- a patient support surface;
- a frame coupled to the patient support surface;
- a sleeve coupled to the frame;
- and
- a caster apparatus coupled to the frame, the caster apparatus including a wheel and a brake system including an actuator, a cable, and a brake member, the cable having a first end portion directly coupled to the actuator and a second end portion coupled to the brake member, actuation of the cable by the actuator causing the brake member to rotate about an axis to brake the wheel the brake member being positioned on an exterior surface of the wheel, the wheel being rotatably coupled to the sleeve and defining a first sweep pattern as the wheel rotates relative to the sleeve, the brake member defining a second sweep pattern as the wheel rotates relative to the sleeve, the first sweep pattern being greater than or equal to the second sweep pattern.

A patient support apparatus comprising:
- a patient support surface;
- a frame coupled to the patient support surface;
- and
- a caster apparatus rotatably coupled to the frame, the caster apparatus including a wheel and a brake member coupled to the wheel, the brake member being external and horizontally adjacent to the wheel, the wheel defining a first sweep perimeter as the caster apparatus rotates relative to the frame, and the brake member defining a second sweep perimeter as the caster apparatus rotates relative to the frame, the first sweep perimeter being greater than or equal to the second sweep perimeter.
