Abstract

A lift table includes a base member, an air powered hydraulic powerpack assembly mounted to the base member, a tabletop, a lift assembly capable of actuated the tabletop relative to the base member, a handle extending upward from the base member, and an air supply docking station. The lift assembly includes a hydraulic cylinder assembly actuated by the air powered hydraulic powerpack. The handle includes a top portion of the handle elevated above the air-powered hydraulic powerpack. The air supply docking station is fixed to the top portion of the handle and is in fluid communication with the air-powered hydraulic powerpack assembly.

First claim

We claim:

1. A lift table, comprising:
(a) a base member;
(b) a tabletop assembly, wherein the tabletop assembly comprises a table base and an adjustable top, wherein the adjustable top is configured to pivot about a pivot axis relative to the table base such that the adjustable top is configured to define a plurality of angles relative to the table base;
(c) a lift assembly configured to adjust the height of the tabletop assembly relative to the base member between a lowered configuration and a raised configuration; and
(d) a table tilt assembly configured to drive the pivoting of the adjustable top relative to the table base between the plurality of angles,
wherein the table tilt assembly comprises a jack screw having an engagement fitting configured to be engaged by a torque input tool in order to adjust the tilt of the tabletop,
wherein the table tilt assembly further comprises a threaded nut fixed against movement relative to the table base,
wherein the jack screw is engaged with the threaded nut,
wherein the table tilt assembly further comprises a pair of flanges fixed to the table base, and
wherein the threaded nut is interposed between the pair of flanges.

2. The lift table of claim 1 , wherein the table tilt assembly further comprises a second jack screw having a second engagement fitting configured to be engaged by the torque input tool in order to adjust the tilt of the tabletop.

3. The lift table of claim 2 , wherein the table tilt assembly further comprises a second threaded nut fixed to the table base, wherein the second jack screw is engaged with the second threaded nut.

4. The lift table of claim 3 , wherein the jack screw and the second jack screw are located on a common longitudinal end of the tabletop assembly.

5. The lift table of claim 4 , wherein the jack screw and the second jack screw are located on opposite lateral sides of the common longitudinal end of the tabletop assembly.

6. A lift table, comprising:
(a) a base member;
(b) a tabletop assembly, wherein the tabletop assembly comprises a table base and an adjustable top, wherein the adjustable top is configured to pivot about a pivot axis relative to the table base such that the adjustable top is configured to define a plurality of angles relative to the table base;
(c) a lift assembly configured to adjust the height of the tabletop assembly relative to the base member between a lowered configuration and a raised configuration; and
(d) a table tilt assembly configured to drive the pivoting of the adjustable top relative to the table base between the plurality of angles,
wherein the table tilt assembly comprises a jack screw having a torque transfer fitting configured to be engaged by a torque input tool in order to adjust the tilt of the tabletop,
wherein the table tilt assembly comprises a threaded nut fixed against translation relative to the table base,
wherein the jack screw is engaged with the threaded nut,
wherein the table tilt assembly comprises a pair of flanges fixed to the table base, and
wherein the threaded nut is fixed to the pair of flanges in order to fix the threaded nut to the table base.

7. The lift table of claim 6 , wherein the table base defines an outer perimeter, and wherein the pair of flanges extend away from the outer perimeter such that the threaded nut is located outside the outer perimeter.

8. The lift table of claim 6 , wherein the torque transfer fitting comprises a recessed opening defined by the jack screw.

9. The lift table of claim 6 , wherein the lift assembly comprises a scissor lift.

10. The lift table of claim 9 , wherein the lift assembly comprises a hydraulic cylinder.

11. The lift table of claim 6 , wherein the table tilt assembly comprises a second threaded nut and a second jack screw, and wherein the second threaded nut and the second jack screw are located at a common end of the table base relative to the jack screw and the threaded nut.

12. The lift table of claim 11 , wherein the second threaded nut is fixed to the table base.

13. The lift table of claim 12 , wherein the second jack screw is threadably coupled to the second threaded nut.

14. The lift table of claim 13 , wherein the jack screw and the second jack screw are configured to actuate vertically relative to the table base.

15. A lift table, comprising:
(a) a base member;
(b) a tabletop assembly, wherein the tabletop assembly comprises a table base and an adjustable top, wherein the adjustable top is configured to pivot about a pivot axis relative to the table base such that the adjustable top is configured to define a plurality of angles relative to the table base, and wherein the table base defines an outermost perimeter;
(c) a lift assembly configured to adjust the height of the tabletop assembly relative to the base member between a lowered configuration and a raised configuration; and
(d) a table tilt assembly positioned laterally outside the outermost perimeter defined by the table base, wherein the table tilt assembly is configured to drive the pivoting of the adjustable top relative to the table base between the plurality of angles, and wherein the table tilt assembly comprises a jack screw having a recessed opening configured to be engaged by a torque input tool in order to adjust the tilt of the tabletop, wherein the table tilt assembly comprises a threaded nut fixed against rotation relative to the table base, and wherein the jack screw is engaged with the threaded nut.

16. The lift table of claim 15 , wherein the table tilt assembly comprises a threaded nut fixed relative to the table base, and wherein the jack screw is engaged with the threaded nut.

17. The lift table of claim 16 , wherein the table tilt assembly further comprises a second threaded nut and a second jack screw.
