Abstract

A hand exercising device with selectively adjustable strength includes a first and second handle pivotably coupled with a spring biased between them, the spring pivotably coupled to the first handle, and a spring positioner coupled to an end of the spring configured to be selectively positioned among a plurality of grooves within the second handle.

Claims (25)

1. A hand exerciser comprising:

a first handle;

a second handle pivotally coupled to the first handle;

a spring biased between the first handle and second handle, wherein the spring is pivotally coupled to the first handle;

a spring positioner operably disposed on an end of the spring;

a pin at least partially disposed within the spring positioner extending away therefrom and extending through the spring disposed on the spring positioner and wherein the pin is configured to engage directly with one of a plurality of grooves through movement of the spring positioner, and

wherein the spring positioner comprises a grip portion accessible through an opening between the first and second handle and for selectively moving the pin and thus the position of the spring among the plurality of grooves in the second handle.

2. The hand exerciser of claim 1 , wherein the pin traverses within the spring running through the spring positioner to engage the plurality of grooves.

3. The hand exerciser of claim 1 , wherein the pin comprises a detent pin.

4. The hand exerciser of claim 1 and further comprising a stop system comprised of symmetrical protrusions and divots configured to engage when said first and second handles are separated at a maximal position.

5. The hand exerciser of claim 1 , wherein the spring is coupled to a pivot within a first cavity located within an upper portion of the first handle.

6. The hand exerciser of claim 1 , wherein the plurality of grooves are disposed within a second cavity located within an upper portion of the second handle.

7. The hand exerciser of claim 1 , wherein the plurality of grooves correspond to a plurality of exercise strength levels.

8. The hand exerciser of claim 1 , wherein the plurality of grooves includes four grooves.

9. The hand exerciser of claim 1 , wherein the first handle includes a palm grip.

10. The hand exerciser of claim 1 , wherein the second handle includes a finger grip.

11. The hand exerciser of claim 1 , wherein a lower portion of the second handle is tapered.

12. A hand exerciser comprising:

a first and second handle pivotally coupled together;

a spring positioned between the first and second handles, the spring having first and second ends, the first end of the spring being pivotally connected to the first handle and the second handle having one of a plurality of engagement positions with the second end of the spring engaging without attachment to one of the plurality of engagement positions within the second handle to vary the force when the handles are moved towards each other;

a spring positioner comprising a grip portion positioned between the spring and the second handle and for selectively moving the spring among the plurality of engagement portions within the second handle; and

a pin traversing within the spring and running through the spring positioner to engage directly with the one of the plurality of grooves for positioning the spring.

13. The hand exerciser of claim 12 wherein the plurality of engagement positions includes a plurality of grooves positioned on the second handle.

14. The hand exerciser of claim 13 wherein the plurality of grooves are disposed within a cavity located within the second handle.

15. The hand exerciser of claim 12 wherein the spring is coupled to a pivot within a first cavity located within an upper portion of the first handle.
