Abstract

Claims (54)

1. A patient lift comprising:

a base;

one or more casters supporting the base for movement relative to a support surface;

a mast supported by the base and extending generally upwards;

an elongated boom mounted for pivotal movement relative to the mast and extending in a forward direction, the boom adapted to support a patient;

an actuator operatively connected to the boom, the actuator adapted to be driven to move the boom relative to the mast in order to move the supported patient relative to the support surface; and

a handle assembly mounted to the mast, the handle assembly including a first side handle that extends to a position forward of the mast and a second side handle that extends to a position forward of the mast, wherein the distance between the first side handle and the second side handle increases in the forward direction.

2. The patient lift of claim 1 , the first side handle including a portion that extends to a position forward of the mast and is substantially parallel to the support surface.

3. The patient lift of claim 1 , the first side handle including a lower bar that is substantially parallel to the support surface and an upper bar that is substantially parallel to the support surface.

4. The patient lift of claim 1 , the handle assembly adapted so that a side force may be applied to the first side handle in a direction substantially transverse to the forward direction and through the center of gravity of the lift when the lift is supporting the patient.

5. The patient lift of claim 4 , wherein the handle assembly is adapted so that the lift can be moved in a direction transverse to the forward direction by applying the side force to the first side handle.

6. A patient lift comprising:

a base;

casters supporting the base for movement relative to a support surface;

a mast extending from the base;

an elongated boom mounted for pivotal movement relative to the mast and extending in a forward direction, the boom adapted to support a patient;

an actuator operatively connected to the boom, the actuator adapted to be driven to move the boom relative to the mast in order to move the supported patient relative to the support surface; and

a handle assembly mounted on the mast and extending in the forward direction so that a side force may be applied to the handle assembly in a direction substantially transverse to the forward direction and through the loaded center of gravity of the lift when the lift is supporting a bariatric patient.

7. The patient lift of claim 6 , the handle assembly adapted so that the lift can be moved in a direction transverse to the forward direction by applying the side force to the handle assembly in the direction transverse to the forward direction.

8. The patient lift of claim 7 wherein the boom is adapted to support a bariatric patient.

9. The patient lift of claim 7 , wherein the handle assembly includes a first side handle that extends in the forward direction a sufficient distance from the mast to allow an attendant to grip the first side handle while tending to the patient.

10. The patient lift of claim 9 , further comprising a second side handle that extends in the forward direction a sufficient distance from the mast to allow an attendant to grip the second side handle while tending to the patient.

11. The patient lift of claim 7 , wherein the handle assembly includes a first side handle that is mounted to the mast and extends in the forward direction to a position forward of the mast.

12. The patient lift of claim 11 , wherein the first side handle comprises a bar extending at an angle from the forward direction.

13. The patient lift of claim 11 , wherein the first side handle includes a portion extending substantially in the forward direction.

14. The patient lift of claim 11 , wherein the first side handle includes an upper bar, a lower bar, and a connecting bar that is attached to the upper bar and the lower bar.

15. The patient lift of claim 11 , wherein the handle assembly includes a second side handle that is mounted to the mast and extends in the forward direction to a position forward of the mast, and wherein the distance between the first side handle and the second side handle increases in the forward direction.

16. A patient lift comprising:

a base;

casters supporting the base for movement relative to a support surface;

a mast supported by the base and extending generally upwards;

an elongated boom mounted for pivotal movement relative to the mast and extending in a forward direction, the boom adapted to support a patient;

an actuator operatively connected to the boom, the actuator adapted to be driven to move the boom relative to the mast in order to move the supported patient relative to the support surface; and

a handle assembly mounted on the mast, the handle assembly including a rear handle that is attached to the mast at two points, the handle assembly further including a first side handle that extends in the forward direction from the rear handle, the first side handle attached to the rear handle at two points.

17. The patient lift of claim 16 , wherein the first side handle extends to a position forward of the mast.

18. The patient lift of claim 17 , the first side handle including a lower bar and an upper bar.

19. The patient lift of claim 18 , further comprising an extended handle that is connected to the lower bar and the upper bar.

20. The patient lift of claim 19 , the handle assembly further comprising a second side handle that extends in the forward direction from the rear handle to a position forward of the mast, the second side handle attached to the rear handle at two points, the second side handle including a lower bar, an upper bar and an extended handle that is connected to the lower bar and the upper bar.

21. A patient lift comprising:

a base;

one or more casters supporting the base for movement relative to a support surface;

a mast supported by the base and extending generally upwards;

an elongated boom mounted for pivotal movement relative to the mast and extending in a forward direction, the boom adapted to support a patient;

an actuator operatively connected to the boom, the actuator adapted to be driven to move the boom relative to the mast in order to move the supported patient relative to the support surface; and

a handle assembly mounted to the mast, the handle assembly including a first side handle that extends to a position forward of the mast, the first side handle including a lower bar that is substantially parallel to the support surface and an upper bar that is substantially parallel to the support surface.

22. A patient lift comprising:

a base;

casters supporting the base for movement relative to a support surface;

a mast extending from the base;

an elongated boom mounted for pivotal movement relative to the mast and extending in a forward direction, the boom adapted to support a patient;

an actuator operatively connected to the boom, the actuator adapted to be driven to move the boom relative to the mast in order to move the supported patient relative to the support surface; and

a handle assembly mounted on the mast, the handle assembly adapted so that a side force may be applied to the handle assembly in a direction substantially transverse to the forward direction and through the loaded center of gravity of the lift when the lift is supporting the patient;

the handle assembly adapted so that the lift can be moved in a direction transverse to the forward direction by applying the side force to the handle assembly in the direction transverse to the forward direction;

wherein the handle assembly includes a first side handle that is mounted to the mast and extends in the forward direction to a position forward of the mast, the first side handle includes an upper bar, a lower bar, and a connecting bar that is attached to the upper bar and the lower bar.
