Abstract

A positionable tool support device is mounted near a work surface for supporting a tool for a user. The tool support device includes a surface mount to secure the tool support device to a support surface. A gravity-balancing articulated arm assembly is coupled to and extends from the surface mount. The gravity-balancing articulated arm assembly is selectively adjustable about both vertical and horizontal axes. A rigid support extension is coupled to the gravity-balancing articulated arm assembly for selective rotation relative to the gravity-balancing articulated arm assembly. A flexible tensile member is coupled to and extends, in a relaxed state, vertically downward from the rigid support extension. The tensile member is coupled to the tool.

First claim

The invention claimed is:

1. A positionable tool support device, configured to be mounted near a work surface for supporting a tool for a user, comprising:
a surface mount configured to secure the tool support device to a support surface;
a gravity-balancing articulated arm assembly coupled to and extending from the surface mount, said gravity-balancing articulated arm assembly being selectively adjustable about both vertical and horizontal axes relative to the surface mount;
a rigid support extension coupled to the gravity-balancing articulated arm assembly;
a flexible tensile member coupled to and extending, in a relaxed state, vertically downward from the rigid support extension, wherein the tensile member is configured to be coupled to the tool; and
in combination, a tool directly supported by the tensile member, said tool including a handle portion configured to be grasped by the user, an opposing end portion carrying a work implement, and an intermediate body portion extending between the handle portion and the opposing end portion, said tensile member being coupled to the tool at the intermediate body portion.

2. The positionable tool support device of claim 1 , wherein the support extension is selectively rotatable relative to the gravity-balancing articulated arm assembly.

3. The positionable tool support device of claim 1 , wherein said rigid support extension extends above the user of the tool support device.

4. The positionable tool support device of claim 1 , wherein the gravity-balancing articulated arm assembly extends upward from the surface mount.

5. The positionable tool support device of claim 1 , wherein the tensile member is comprised of a loop of flexible sling, and the tensile member is configured to be coupled to the tool using a girth hitch knot formed by the loop.

6. The positionable tool support device of claim 1 , wherein the tensile member is comprised of a double-loop sling, and the tensile member is configured to be coupled to the tool using a choker hitch knot formed by the double-loop sling.

7. The positionable tool support device of claim 1 , wherein the tensile member is comprised of a daisy chain loop sling, and the tensile member is configured to be coupled to the tool using a choker hitch knot formed by the daisy chain loop sling.

8. The positionable tool support device of claim 1 , wherein the tensile member is comprised of a double-loop sling, the tool support device further comprising an adjustable loop sling and a ring, wherein the double-loop sling is coupled to the adjustable loop sling by the ring.

9. The positionable tool support device of claim 8 , further comprising a selective coupler, wherein the double-loop sling is coupled to the adjustable loop sling by the selective coupler.

10. The positionable tool support device of claim 9 , further comprising a swivel, wherein the double-loop sling is coupled to the selective coupler by the swivel.

11. The positionable tool support device of claim 8 , further comprising a swivel, wherein the double-loop sling is coupled to the adjustable loop sling by the swivel.

12. The positionable tool support device of claim 8 , further comprising an adjustable sling coupled to the ring and configured to be coupled to the tool.

13. The positionable tool support device of claim 8 , further comprising an adjustable sling coupled to the adjustable loop sling and configured to be coupled to the tool.

14. The positionable tool support device of claim 1 , wherein the tensile member is comprised of a double-loop sling, the tool support device further comprising a clamp and a selective coupler, wherein the double-loop sling is coupled to the clamp by the selective coupler.

15. The positionable tool support device of claim 14 , further comprising a swivel, wherein the double-loop sling is coupled to the clamp by the swivel.

16. The positionable tool support device of claim 1 , further comprising a selective locking device that selectively fixes a relative position of the gravity-balancing articulated arm assembly and the rigid support extension in an axial plane.

17. The positionable tool support device of claim 1 , further comprising an overhead track along which a position of the surface mount can be changed.

18. The positionable tool support device of claim 17 , wherein the surface mount is configured to receive power from the overhead track, the tool support device further comprising a power supply conduit configured to transfer power from the surface mount to the tool.

19. The positionable tool support device of claim 18 , further comprising a winch coupled to the rigid support extension, wherein the winch is configured to shorten or lengthen the tensile member and the power supply conduit.

20. The positionable tool support device of claim 1 , further comprising a winch coupled to the rigid support extension, wherein the winch is configured to shorten or lengthen the tensile member.

21. The positionable tool support device of claim 1 , further comprising a power supply conduit configured to transfer power from the surface mount to the tool.

22. The positionable tool support device of claim 1 , further comprising a ratchet coupled to the tensile member, wherein the ratchet is configured to shorten or lengthen the tensile member.

23. The positionable tool support device of claim 1 , further comprising:
a second rigid support extension coupled to the gravity-balancing articulated arm assembly; and
a second flexible tensile member coupled to and extending, in a relaxed state, vertically downward from the second rigid support extension, wherein the second tensile member is configured to be coupled to the tool.
