Abstract

An ergonomic device is for a writing instrument. The ergonomic device includes a body having a first curved side, and a second curved side opposite to the first curved side and to be adjacent to the writing instrument. The ergonomic device also includes a first arm between the first curved side and the second curved side and extending outwardly from the body. The first arm defines a first opening to receive an index finger and a middle finger of a user. The ergonomic device includes a second arm between the first curved side and the second curved side and opposite to the first arm. The second arm extends outwardly from the body and defines a second opening to receive a thumb of the user.

Claims (42)

1 . An ergonomic device for a writing instrument, the ergonomic device comprising:

a body comprising

a first curved side,

a second curved side opposite to the first curved side,

a lower surface being transverse to and being between the first curved side and the second curved side, and

an upper surface opposite to the lower surface;

a first arm between the first curved side and the second curved side and extending outwardly from the body, the first arm defining a first opening to receive an index finger and a middle finger of a user; and

a second arm between the first curved side and the second curved side and opposite to the first arm, the second arm extending outwardly from the body and defining a second opening to receive a thumb of the user, the first arm and the second arm defining a recess above the upper surface for receiving the writing instrument;

the index finger, the middle finger, and the thumb to grasp the writing instrument and position it freely through the recess.

2 . The ergonomic device of claim 1 wherein the first opening is larger than the second opening.

3 . The ergonomic device of claim 1 wherein the lower surface comprises a flat surface.

4 . The ergonomic device of claim 1 wherein the lower surface comprises a first slot adjacent to the first curved side, and a second slot opposite to the first slot and adjacent to the second curved side.

5 . The ergonomic device of claim 1 wherein the lower surface comprises a closed passageway to receive the writing instrument.

6 . The ergonomic device of claim 5 wherein the closed passageway is round-shaped.

7 . The ergonomic device of claim 1 wherein the first arm comprises a first segment and a second segment opposite to the first segment, the first segment having a first curved end, a second curved end, and a medial portion between the first curved end and the second curved end, the medial portion protruding inwardly into the first opening.

8 . The ergonomic device of claim 1 wherein the second opening comprises a round-shaped opening.

9 . The ergonomic device of claim 1 wherein the first opening comprises an elongate-oval-shaped opening.

10 . A method for making an ergonomic device for a writing instrument, the method comprising:

forming a body comprising

a first curved side,

a second curved side opposite to the first curved side,

a lower surface being transverse to and being between the first curved side and the second curved side, and

an upper surface opposite to the lower surface;

forming a first arm between the first curved side and the second curved side and extending outwardly from the body, the first arm defining a first opening to receive an index finger and a middle finger of a user; and

forming a second arm between the first curved side and the second curved side and opposite to the first arm, the second arm extending outwardly from the body and defining a second opening to receive a thumb of the user, the first arm and the second arm defining a recess above the upper surface for receiving the writing instrument;

the index finger, the middle finger, and the thumb to grasp the writing instrument and position it freely through the recess.

11 . The method of claim 10 wherein the forming of the first arm comprises forming the first opening to be larger than the second opening; wherein the forming of the body comprises forming the lower surface to comprise a flat surface, and a first slot adjacent to the first curved side, and a second slot opposite to the first slot and adjacent to the second curved side.

12 . The method of claim 10 wherein the forming of the body, the forming of the first arm, and the forming of the second arm are performed integrally in a single step.

13 . An ergonomic device for a writing instrument, the ergonomic device comprising:

a body comprising

a first curved side,

a second curved side opposite to the first curved side, and

a surface being transverse to and being between the first curved side and the second curved side, the surface comprising a first slot adjacent to the first curved side, and a second slot opposite to the first slot and adjacent to the second curved side;

a first arm between the first curved side and the second curved side and extending outwardly from the body, the first arm defining a first opening to receive an index finger and a middle finger of a user; and

a second arm between the first curved side and the second curved side and opposite to the first arm, the second arm extending outwardly from the body and defining a second opening to receive a thumb of the user.

14 . The ergonomic device of claim 13 wherein the first opening is larger than the second opening.

15 . The ergonomic device of claim 13 wherein the surface comprises a flat surface.

16 . The ergonomic device of claim 13 wherein the surface comprises a closed passageway to receive the writing instrument.

17 . The ergonomic device of claim 16 wherein the closed passageway is round-shaped.

18 . The ergonomic device of claim 13 wherein the first arm comprises a first segment and a second segment opposite to the first segment, the first segment having a first curved end, a second curved end, and a medial portion between the first curved end and the second curved end, the medial portion protruding inwardly into the first opening.

19 . The ergonomic device of claim 13 wherein the second opening comprises a round-shaped opening.

20 . The ergonomic device of claim 13 wherein the first opening comprises an elongate-oval-shaped opening.
