Abstract

The present invention is a tool handle and method of use that has an ergonomic configuration including a proximal grip, medial portion and distal grip having three angular inflections in the same vertical plane allowing greater ease of use.

Claims

1. A tool handle for use with a tool head comprising:

(a) a proximal grip;

(b) a medial portion, connected to said proximal grip at a first angular vertex;

(c) a distal grip connected to said medial portion at a second angular vertex;

(d) a shaft connected at a first end to said distal grip at a third angular vertex and at a second end to a tool head;

wherein each of said angular vertices are along a contiguous handle with three angular inflections.

2. The tool handle of claim 1 wherein said inflections are each above a longitudinal axis.

3. The tool handle of claim 1 wherein said inflections lie in a common vertical plane.

4. The tool handle of claim 1 wherein said proximal grip forms an angular vertex with the medial portion such that the angle x formed on the underside of said handle is obtuse.

5. The tool handle of claim 4 comprising a distal grip that forms an angular vertex with the distal end of said medial portion such that the angle y formed on the underside of said handle is obtuse.

6. The tool handle of claim 5 comprising a distal grip that forms an angular vertex with a shaft such that the angle z is formed on the upper side of said handle is obtuse.

7. The tool handle of claim 6 wherein angle x, angle y, and angle z are congruent.

8. The tool handle of claim 6 wherein each of angles x, y and z have a measure between 110°

-170°

.

9. The tool handle of claim 1 wherein said handle further comprises central channel.

10. The tool handle of claim 1 wherein said medial portion further comprises a protrusion elevated from the upper surface of said medial portion.

11. The tool handle of claim 10 wherein said protrusion includes an interior protrusion cavity.

12. The tool handle of claim 10 wherein said protrusion has indicia incorporated into the upper surface.

13. The tool handle of claim 1 comprising a tool head.

14. The tool handle of claim 13 formed of a single contiguous piece.

15. The tool handle of claim 13 wherein said tool head is a rake, shovel, or hoe.

16. The tool handle of claim 13 wherein said tool head is formed as a single contiguous unit with the handle.

17. The tool handle of claim 13 comprising a connect/disconnect for the attachment and detachment of a tool head.

18. A tool comprising a handle and a tool head, said handle including:

(a) a proximal grip;

(b) a medial portion, connected to said proximal grip at a first angular vertex;

(c) a distal grip connected to said medial portion at a second angular vertex;

(d) a shaft connected at a first end to said distal grip at a third angular vertex and at a second end to a tool head;

wherein each angular vertex is congruent and obtuse.

19. The tool of claim 18 wherein each angular vertex lie in a common vertical plane.

20. A method of using the tool of claim 20 comprising the steps of:

(a) grasping said proximal grip with one hand;

(b) grasping said distal grip with a second hand;

(c) positioning said distal grip such that said tool head engages a desired functional position;

(d) moving said proximal grip downward;

said downward motion creating an ergonomically favorable motion for using said tool.
