Abstract

Claims (34)

1 . A hospital bed comprising:

a base frame;

the base frame includes a first side member;

a first leg connected to the first side member;

the base frame includes a second side member;

a second leg connected to the second side member;

an actuator connected to the first leg to cause the first leg to move from a retracted position to an extended position; and

wherein in the retracted position, the first leg is substantially parallel to the first side member of the base frame and in the extended position, the first leg is substantially transverse to the first side member of the base frame.

2 . A hospital bed as in claim 1 wherein the second leg has a retracted position and an extended position, in the retracted position, the second leg is substantially parallel to the second side member of the base frame and in the extended position, the second leg is substantially transverse to the second side member of the base frame.

3 . A hospital bed as in claim 2 further including a second actuator connected to the second leg to cause the second leg to move from the retracted position to the extended position.

4 . A hospital bed as in claim 3 further including a third leg connected to the first side member.

5 . A hospital bed as in claim 4 wherein the first actuator is connected to the third leg to cause the third leg to move from a retracted position to an extended position.

6 . A hospital bed as in claim 5 further including a fourth leg connected to the second side member.

7 . A hospital bed as in claim 6 wherein the second actuator is connected to the fourth leg to cause the fourth leg to move from a retracted position to an extended position.

8 . A hospital bed as in claim 1 wherein the first leg is rotatably connected to the first side member and the second leg is rotatably connected to the second side member.

9 . A hospital bed as in claim 1 wherein the first leg includes a shaft portion, the shaft portion angled inwardly toward the first side member such that a longitudinal axis of the shaft portion crosses a vertical axis extending through the first side member.

10 . A hospital bed as in claim 1 further including one or more casters connected to the base frame.

11 . A hospital bed as in claim 1 further including a patient deck.

12 . A hospital bed as in claim 11 further including an intermediate frame connected to the patient deck and the base frame.

13 . A hospital bed as in claim 11 wherein the first leg must be in the extended position in order for the patient deck to be tilted relative to the horizontal.

14 . A hospital bed as in claim 13 further including a locking system that stabilizes the bed prior to the patient deck being tilted into a tilted position.

15 . A hospital bed as in claim 14 wherein the locking system stabilizes the bed by locking one or more casters.

16 . A hospital bed as in claim 14 wherein the locking system is in a lock mode before allowing the patient deck to go into a tilted position.

17 . A hospital bed as in claim 14 wherein the locking system includes a brake lock function, when the patient deck is in the tilted position, the locking system prevents the brake lock function from becoming disengaged until the patient deck is rotated back to a generally horizontal position.

18 . A hospital bed comprising:

a base frame;

the base frame includes a first side member;

a first leg connected to the first side member;

the base frame includes a second side member;

a second leg connected to the second side member;

an actuator connected to the first leg to cause the first leg to move from a retracted position to an extended position; and

an emergency release to allow the first leg to be disassociated with the actuator, so that the first leg can be manually moved between the retracted position and the extended position.

19 . A hospital bed as in claim 18 including a second actuator connected to the second leg to cause the second leg to move from the retracted position to the extended position, the emergency release to allow the second leg to be disassociated with the second actuator, so that the second leg can be manually moved between the retracted position and the extended position.

20 . A hospital bed as in claim 18 further including a third leg connected to the first side member and a fourth leg connected to the second side member.
