Bed base frame
A bed base frame assembly of a bed generally comprises a base frame, a plurality of steerable and lockable casters, a lateral support assembly at the first and second sides of the base frame assembly, and an in-line support assembly at the foot end of the base frame assembly. The lateral support assembly may further include: a base frame; a first leg and a second leg rotatably connected to the base frame; a first actuator connected to the first leg and the second leg, wherein the first leg and the second leg rotate from the retracted position to the extended position; a third leg and a fourth leg rotatably connected to the base frame; and a second actuator connected to the third leg and the fourth leg, wherein the third leg and the fourth leg rotate from the retracted position to the extended position.

a first leg connected to the first side member of the frame;
the first leg has a first position, the first position is outward from the foot end of the first side member.
2. The hospital bed as in claim 1 , wherein in the first position the first leg is at a first extended angle, the first extended angle is between 1 degree to 179 degrees.
3. The hospital bed as in claim 2 , wherein the first extended angle is about 90 degrees and relatively in-line to the first side member.
4. The hospital bed as in claim 1 , wherein the first leg has a retracted position.
5. The hospital bed as in claim 4 , wherein in the retracted position the first leg extends outward less than when the first leg is in the first position.
6. The hospital bed as in claim 4 , wherein in the retracted position, the first leg is substantially perpendicular to the first side member.
7. The hospital bed as in claim 4 , wherein the first leg is rotatably connected to the first side member.
8. The hospital bed as in claim 4 , wherein the first leg is configured to be manually moved from the first position to the retracted position.
9. The hospital bed as in claim 4 , wherein the first leg is configured to be automatically moved from the first position to the retracted position.
10. The hospital bed as in claim 9 , further including an actuator, the actuator moves the first leg from the first position to the retracted position.
11. The hospital bed as in claim 10 , further including a release to allow the first leg to be disassociated with the actuator.
12. The hospital bed as in claim 4 , wherein the first leg is automatically controlled.
13. The hospital bed as in claim 1 , wherein the first leg must be in the first position in order for the patient deck to be angularly rotated relative to the horizontal.
14. The hospital bed as in claim 1 , wherein the first leg is configured to be automatically moved to the first position prior to the patient deck being angularly rotated relative to the horizontal.
15. The hospital bed as in claim 1 , wherein the first leg includes a wheel.
16. The hospital bed as in claim 1 , wherein the frame includes a second side member, the second side member includes a foot end, a second leg connected to the second side member of the frame, the second leg has a first position, the first position of the second leg is outward from the foot end of the second side member.
17. The hospital bed as in claim 16 , wherein in the first position the second leg is at a second extended angle, the second extended angle is between 1 degree to 179 degrees.
18. The hospital bed as in claim 17 , wherein the second extended angle is about 90 degrees and relatively in-line to the second side member.
19. The hospital bed as in claim 16 , wherein the second leg has a retracted position.
20. The hospital bed as in claim 19 , wherein in the retracted position the second leg extends outward less than when the second leg is in the first position.
21. The hospital bed as in claim 19 , wherein in the retracted position, the second leg is substantially perpendicular to the second side member.
22. The hospital bed as in claim 16 , wherein the second leg is rotatably connected to the second side member.
23. The hospital bed as in claim 19 , wherein the second leg is configured to be manually moved from the first position to the retracted position.
24. The hospital bed as in claim 19 , wherein the second leg is configured to be automatically moved from the first position to the retracted position.
25. The hospital bed as in claim 19 , further including a second actuator, the second actuator moves the second leg from the first position to the retracted position.
26. The hospital bed as in claim 25 , further including a release to allow the second leg to be disassociated with the second actuator.
27. The hospital bed as in claim 19 , wherein the second leg is automatically controlled.
28. The hospital bed as in claim 16 , wherein the first leg must be in the first position and the second leg must be in the first position in order for the patient deck to be angularly rotated relative to the horizontal.
29. The hospital bed as in claim 16 , wherein the first leg is configured to be automatically moved to the first position and the second leg is configured to be automatically moved to the first position of the second leg prior to the patient deck being angularly rotated relative to the horizontal.
