Abstract

A vehicle for use in hospitals, and the like, giving better mobility, steering, braking and passenger handling while providing comfort to the passengers from the time they lay down until they are standing on the side through the rotation and tilting ability of the frame.

Claims

1. A method of translating a hospital bed, comprising:

rotating a patient sleep support surface having back, seat and leg sections to a side egress chair position;

rotating side rails attached to each side of the patient sleep surface with the sleep surface;

tilting the seat section down with a forwardmost part of the seat section residing below a rearwardmost part of the seat section while the back section is held upright above the seat section to define a stand-assist side egress position thereby facilitating a patient'"'"'s egress from the bed; and

translating the side rails to extend upright on either side to the patient sleep support surface when the bed is in the side egress stand-assist position.

2. The method of claim 1, further comprising tilting the back, seat and leg sections to a patient comfort position when the bed is in a normal longitudinally aligned position such that the seat section angles upwardly and the back and foot sections angle downwardly.

3. The method of claim 1, wherein the rotating step is carried out using a rotating circular plate that is slidably attached to a tilting platform that resides above and in cooperating communication with a lifting mechanism.

4. The method of claim 3, wherein the rotating plate is in communication with a lifting mechanism that resides under the rotating plate, and wherein the rotating plate supports a tilt bar mount that holds a main support rod of the sleep support surface with the main support rod residing under a front of the seat section and an adjacent portion of the back section, and wherein the method further comprises positioning the main support rod higher than a front of the seat section to tilt the seat section forward and positioning the main support rod lower than the front section of the seat section to tilt the seat section backward.

5. A method of translating a hospital bed, comprising:

slidably rotating a plate that supports back, seat and leg sections of a patient sleep support surface from a hospital bed position to a side egress chair position, wherein in the side egress chair position the seat section is substantially horizontal; and

tilting the seat section down with a forwardmost part of the seat section residing below a rearwardmost part of the seat section while the back section is held substantially upright to define a stand-assist side egress position thereby facilitating a patient'"'"'s standing egress from the bed; and

wherein the rotating step allows a user to selectively rotate the bed to a left or right side for the side egress positions.

6. The method of claim 5, wherein the rotating plate is a planar circular plate.

7. The method of claim 5, wherein the rotating plate is slidably attached to a tilting platform that resides above and in cooperating communication with a lifting mechanism, the method further comprising lifting the tilting platform to lift the patient sleep surface.

8. The method of claim 5, wherein the rotating plate is in communication with a lifting mechanism that resides under the rotating plate, and wherein the rotating plate supports a tilt bar mount that holds a main support rod of the sleep support surface with the main support rod residing under a front of the seat section and an adjacent portion of the back section, and wherein the method further comprises positioning the main support rod higher than a front of the seat section to tilt the seat section forward and positioning the main support rod lower than the front section of the seat section to tilt the seat section backward.

9. The method of claim 5, wherein the rotating step can be carried out to be able to rotate the patient sleep support surface 360 degrees.

10. A method of translating a hospital bed with back, seat and leg sections, comprising:

moving the hospital bed through a plurality of different positions, including;

(a) from a comfort position where, when viewed from a side, the seat section angles upwardly and the back and leg sections angle downwardly;

to (b) side chair position; and

(c) to a side stand-assist walkout exit position where the seat section angles downwardly so that the forwardmost portion of the seat section is closest to a floor,

wherein the moving is carried out so that a user can selectively position the bed so that the side chair and side stand assist side walkout positions can be on either side of the bed at either 90 degrees or 270 degrees.
