Abstract

There is provided an ergonomic handle device for holding tools including an approximately spherical holder having an outer surface and surrounding three slots; any two of the three slots are perpendicular to each other; each of the three slots extends from a first end to a second end on two opposite sides of the approximately spherical holder, in a radial direction and through a center of the approximately spherical holder; each of the three slots being sized and configured for engaged receipt of a handle of the tool, wherein the handle of the tool passes through the first end of one of the three slots until the handle of the tool passes through the second end of the slot; a plurality of grip indentations on the outer surface of the approximately spherical holder; and wherein the user may operate the tool by gripping the grip indentations of the approximately spherical holder for an extended time without getting stiff hands and fingers.

Claims (30)

1. An ergonomic handle device for holding tools, said ergonomic handle device comprising:

an approximately spherical holder having an outer surface and surrounding three slots;

any two of said three slots are perpendicular to each other;

each of said three slots extends from a first end to a second end on two opposite sides of said approximately spherical holder, in a radial direction and through a center of said approximately spherical holder;

each of said three slots being sized and configured for engaged receipt of a handle of the tool, wherein the handle of the tool passes through the first end of one of said three slots until the handle of the tool passes through the second end of the slot;

a plurality of grip indentations on the outer surface of said approximately spherical holder; and

wherein a user may operate the tool by gripping said grip indentations of said approximately spherical holder for an extended time without getting stiff hands and fingers.

2. The ergonomic handle device for holding tools as recited in claim 1 , wherein one of said approximately spherical holder is sized and configured to fit within the palm of the user's hand.

3. The ergonomic handle device for holding tools as recited in claim 1 , wherein at least one of said three slots is sized and configured for engaged receipt of a particularly shaped handle of a tool.

4. The ergonomic handle device for holding tools as recited in claim 3 , wherein said tool is a pen.

5. The ergonomic handle device for holding tools as recited in claim 3 , wherein said tool is a knife.

6. The ergonomic handle device for holding tools as recited in claim 3 , wherein said tool is an eating utensil.

7. The ergonomic handle device for holding tools as recited in claim 3 , wherein said tool is a paintbrush.

8. The ergonomic handle device for holding tools as recited in claim 1 , wherein each of said three slots are sized and configured for receipt of a different tool.

9. An ergonomic handle device for holding tools, said ergonomic handle device for holding tools comprising:

an approximately spherical holder having an outer surface and surrounding two slots;

said two slots are perpendicular to each other;

each of said two slots extends from a first end to a second end on two opposite sides of said approximately spherical holder, in a radial direction and through a center of said approximately spherical holder;

each of said two slots being sized and configured for engaged receipt of a handle of the tool, wherein the handle of the tool passes through the first end of one of said two slots until the handle of the tool passes through the second end of the slot; and

wherein a user may operate the tool by gripping onto said approximately spherical holder for an extended time without getting stiff hands and fingers.

10. The ergonomic hand device for holding tools as recited in claim 9 further comprising a plurality of grip indentations on the outer surface of said approximately spherical holder for gripping by the user.

11. The ergonomic handle device for holding tools as recited in claim 9 , wherein each of said two slots are sized and configured for receipt of a different tool.

12. An ergonomic handle device for holding tools, said ergonomic handle device comprising:

an approximately spherical holder having an outer surface and surrounding at least one of a plurality of slots, wherein:

each of said plurality of slots extends from a first end to a second end on two opposite sides of said approximately spherical holder, in a radial direction and through a center of said approximately spherical holder;

each of said plurality of slots being sized and configured for engaged receipt of a handle of the tool, wherein the handle of the tool passes through the first end of one of said plurality of slots until the handle of the tool passes through the second end of the slot; and

wherein a user may operate the tool by gripping onto said approximately spherical holder for an extended time without getting stiff hands and fingers.

13. The ergonomic handle device for holding tools as recited in claim 12 , wherein an intersecting angle of any two of said plurality of slots crossing at the center of said approximately spherical holder is greater than 0° and less than or equal to 90°.

14. The ergonomic hand device for holding tools as recited in claim 12 further comprising a plurality of grip indentations on the outer surface of said approximately spherical holder for gripping by the user.

15. The ergonomic handle device for holding tools as recited in claim 12 , wherein each of said plurality of slots are sized and configured for receipt of a different tool.
