Abstract
A patient-support apparatus includes a patient-support deck coupled to first and second lift systems configured to lift the patient-support deck relative to the floor. The lift systems each include a pair of supports and a carriage coupled to the patient-support deck and suspended from the supports by tethers which are wound and unwound to raise and lower the patient-support deck.
Claims23
A patient-support apparatus comprising
- a plurality of supports,
- a first tether coupled to a first support,
- a second tether coupled to a second support,
- a patient-support platform, the patient-support platform includes a frame, a plurality of deck sections pivotable relative to the frame, a plurality of actuators each coupled to a deck section, the actuators configured to control a pivoting of the deck sections relative to the frame, and
- winding means for winding and unwinding the tethers to vary the height of the patient-support platform relative to the supports such that as the tethers are wound the second tether is wound upon the first tether.

A lift system for a patient-support apparatus comprising
- first and second tethers configured to be coupled to a first portion of the patient-support apparatus, and
- a winder coupled to the tethers distal to the first portion, the winder configured to be coupled to a second portion of the patient-support apparatus and to rotate relative to the second portion of the patient-support apparatus to wind the first tether upon the second tether to vertically raise the second portion relative to the first portion and to unwind the first tether and the second tether to vertically lower the second portion relative to the first portion.
A patient-support apparatus comprising
- a patient-support platform, the patient-support platform includes a frame and a plurality of deck sections pivotable relative to the frame,
- a plurality of columns configured to engage a floor,
- a tether coupled to each column, and
- a winder coupled to the patient-support platform and suspended by the tethers, the winder configured to gather the tethers such that the tethers overlie one another and release the tethers to thereby raise and lower the patient-support platform relative to the floor.

A patient-support apparatus comprising
- a first portion,
- a first and second tethers coupled to a first portion of the patient-support apparatus,
- a second portion of the patient-support apparatus movable relative to the first portion, and
- a winder coupled to the each of the first and second tethers distal to the first portion, the winder supported on the second portion and rotatable relative to the second portion to wind the tethers such that the tethers overlie one another and unwind the first and second tethers to thereby move the second portion of the patient-support apparatus vertically relative to the first portion.
