Abstract

A patient support including a frame, plurality of wheels coupled to the frame, a deck, and a scissor mechanism coupled to the frame and the deck to move the deck from a raised position to a lowered position. The support includes brake mechanism including a brake pad to contact the floor to prevent the patient support from rolling.

Claims

1. A patient support comprising:

a frame;

a plurality of wheels coupled to the frame;

a brake mechanism coupled to the frame, the brake mechanism including a first member having first and second ends, a second member having first and second ends, and a third member configured to contact a floor surface, the first ends of the first and second members being pivotally coupled to the frame, the second ends of the first and second members pivotally coupled to the third member; and

an actuator pivotally coupled to the first member between the first and second ends of the first member.

2. The patient support of claim 1, wherein the first and second members are substantially parallel to one another.

3. The patient support of claim 1, further comprising a spring having first and second ends, the first end of the spring being coupled to the frame, and the second end of the spring being coupled to the brake mechanism to bias the brake mechanism toward a retracted position spaced apart from the floor.

4. The patient support of claim 3, wherein the spring is coupled to the third member.

5. The patient support of claim 1, wherein the frame defines a transverse axis and a longitudinal axis, and at least one brake mechanism is positioned along the transverse axis of the frame.

6. The patient support of claim 5, wherein at least one brake mechanism is positioned along the longitudinal axis of the frame.

7. The patient support of claim 1, further comprising a mattress supported by the frame.

8. A patient support comprising:

a frame;

a deck supported by the frame; and

a deck lift configured to raise and lower the deck, the deck lift including a first mount adapted to be coupled to the frame, a second mount adapted to support the deck, a first link including first and second ends, a second link including first and second ends, and an actuator coupled to the first and second links, the second end of the first and second links coupled to the first mount, the first end of the first and second links coupled to the second mount and moveable relative to the deck, the first ends moving toward one another when the deck is raised and away from one another when the deck is lowered.

9. The patient support of claim 8, further comprising a first and second control link, the first control link coupled on a first end to the first link and on a second end to the first mount, the second control link coupled on a first end to the second link and on a second end to the second mount.

10. A patient support comprising:

a frame;

a deck supported by the frame;

a scissor mechanism operatively coupled to the frame and to the deck; and

an actuator disposed within the scissor mechanism, to move the deck between a raised position and a lowered position.

11. The patient support of claim 10, further comprising a first mount operatively coupled to the deck, the first mount including an aperture sized to receive a portion of the actuator.

12. The patient support of claim 11, further comprising a carriage operatively coupled to the scissor mechanism and operatively coupled to the actuator, wherein actuation of the actuator moves the deck between the raised position and the lowered position.

13. The patient support of claim 12, further comprising a second mount operatively coupled to the frame, the second mount including an aperture sized to receive a portion of the carriage.

14. The patient support of claim 10, wherein the scissor mechanism comprises a first pair of links coupled to a second pair of links, wherein the first pair of links is coupled to the deck and the second pair of links is coupled to the frame.

15. The patient support of claim 14, further comprising a carriage operatively coupled to one of the first and second pair of links and operatively coupled to the actuator, wherein movement of the actuator moves the deck between the raised position and the lowered position.

16. The patient support of claim 15, further comprising a first mount operatively coupled to the deck and to the first pair of links, the first mount including an aperture sized to receive a portion of the actuator.

17. The patient support of claim 16, further comprising a second mount operatively coupled to the frame and to the second pair of links, the second mount including an aperture sized to receive a portion of the carriage.

18. The patient support of claim 17, further comprising a mattress supported by the frame.

19. The patient support of claim 14, further comprising a first control link, the first control link operatively coupled to first pair of links and to the first mount, to control movement of the scissor mechanism when the deck moves between the raised position and the lowered position.

20. The patient support of claim 18, further comprising a second control link, the second control link coupled to the second pair of links and the second mount, to control movement of the scissor mechanism when the deck moves between the raised position and the lowered position.
