Abstract
A patient-support apparatus includes a base, a patient-support deck, a deck-positioning assembly coupling the patient-support deck to the base, and a locking mechanism, the locking mechanism having a first state to prevent longitudinal movement of the patient-support deck relative to the base, and a second state to allow longitudinal movement of the patient-support deck relative to the base.
Claims40
A patient-support apparatus, comprising:
- a base;
- a patient-support deck having a longitudinal length and a transverse width;
- a rod coupled to the patient-support deck;
- and
- a deck-positioning assembly coupling the patient-support deck to the base, the patient-support deck being supported with respect to the deck-positioning assembly for longitudinal movement relative to the base, the deck-positioning assembly including a locking device, the locking device including a portion moveable between first and second positions, the portion of the locking device being configured to engage the rod in the first position to prevent longitudinal movement of the patient-support deck relative to the base, and the portion of the locking device being configured to disengage the rod in the second position to allow longitudinal movement of the patient-support deck relative to the base.

A patient-support apparatus, comprising:
- a base;
- a patient-support deck having a longitudinal length and a transverse width;
- a rod coupled to the patient-support deck;
- a deck-positioning assembly coupling the patient-support deck to the base, the patient-support deck being supported with respect to the deck-positioning assembly for longitudinal movement relative to the base, the deck-positioning assembly including a locking device, the locking device configured to engage the rod in a first state to prevent longitudinal movement of the patient-support deck relative to the base, and disengage the rod in a second state to allow longitudinal movement of the patient-support deck relative to the base, wherein the deck-positioning assembly includes an actuator for selecting between the first state and the second state of the locking device;
- and
- an angle sensor coupled to the deck-positioning assembly and configured to sense a position of at least a portion of the patient-support deck, the angle sensor generating an angle signal that prevents the actuator from selecting the second state of the locking device when the portion of the patient-support deck is in a tilted position.

A patient-support apparatus comprising:
- a base;
- a patient-support deck having a longitudinal length and a transverse width;
- a locking device coupled to the patient-support deck;
- a deck-positioning assembly coupling the patient-support deck to the base, the patient-support deck being supported with respect to the deck-positioning assembly for longitudinal movement relative to the base, the deck-positioning assembly including a longitudinal member, and wherein the locking device is configured to engage the longitudinal member to prevent longitudinal movement of the patient-support deck relative to the base;
- and
- an actuator configured to disengage the locking device from the longitudinal member and thereby allow longitudinal movement of the patient-support deck relative to the base.

- a base;
- a patient-support deck having a longitudinal length and a transverse width;
- a longitudinal member coupled to the patient-support deck;
- and
- a deck-positioning assembly coupling the patient-support deck to the base, the patient-support deck being supported with respect to the deck-positioning assembly for longitudinal movement relative to the base, the deck-positioning assembly including a locking device, the locking device including a portion having a first position engaging the longitudinal member to prevent longitudinal movement of the patient-support deck relative to the base and having a second position disengaging the longitudinal member and thereby longitudinal movement of the patient-support deck relative to the base.

A patient-support apparatus, comprising:
- a base;
- a patient-support deck having a longitudinal length and a transverse width, the patient-support deck being supported with respect to the deck-positioning assembly for longitudinal movement relative to the base;
- a locking device operably coupled to the patient-support deck and configured to prevent longitudinal movement of the patient-support deck relative to the base in a locked state and to allow longitudinal movement of the patient-support deck relative to the base in an unlocked state;
- an actuator operably coupled to the locking device and configured to select between the locked state and the unlocked state of the locking device;
- a controller operably coupled to the actuator and configured to provide a drive signal to the actuator;
- an angle sensor operably coupled to the patient-support deck, the angle sensor configured to sense an angular position of at least a portion of the patient-support deck relative to a transverse axis, the angle sensor further configured to generate an angle signal indicative of the angular position of the portion of the patient-support deck;
- and
- wherein the controller is configured to receive the angle signal from the angle sensor, and to prevent the actuator from placing the locking device in the unlocked state when the patient-support deck is tilted by at least a predetermined angle from horizontal.
