Abstract

A spring is made of a flexible plastic material in generally arcuate shape. This spring of adjustable strength is especially suitable for use in a hand exercising device, which may have optional inserts which, in turn, serve to increase or reduce the strength the grip required; and an optional counting mechanism to indicate desired features of exercise with the grip such as repetitions or time.

Claims

1. A hand exercising device including a spring and two arms extending therefrom, comprising:

a) said spring having an adjustable strength;

b) said spring and said two arms cooperating to unitarily form said hand exercising device;

c) said two arms including a first arm and a second arm;

d) said first arm and said second arm extending from said spring, said spring being a portion centrally located therebetween;

e) a strengthening member cooperating with said hand exercising device to adjust a force required to operate said hand exercising device upwardly or downwardly; and

f) said strengthening member being a rod capable of slidable insertion in said portion.

2. The hand exercising device of claim 1 being a unitary piece.

3. The hand exercising device of claim 1, having an adjustment in the thickness or width of said portion to adjust strength of said hand exercising device.

4. The hand exercising device of claim 1, comprising:

a) said portion being arcuate;

b) and said spring includes a receiving means for accepting at least one strengthening member capable of increasing the strength of said spring, thereby increasing the strength of said hand exercising device.

5. The hand exercising device of claim 4, further comprising:

a) said strengthening member being of a generally cylindrical shape; and

b) said strengthening member being insertable in said portion.

6. The hand exercising device of claim 4, further comprising:

a) said strengthening member being of a generally elongated shape; and

b) said strengthening member surrounding an exterior of said portion.

7. The hand exercising device of claim 4, further comprising

said portion including at least one indentation in an edge thereof.

8. The hand exercising device of claim 7 being a molded plastic article.

9. The hand excising device of claim 4 being a molded plastic article.

10. The hand exercising device of claim 5 having said strengthening member of a generally cylindrical shape.

11. The hand exercising device of claim 10, having a tapering means to adjust strength of said generally cylindrical shape.
