Abstract

The invention is a semi-resilient exercise grip that has a non-resilient particulate core surrounded by a resilient rubber covering. Within the core there is also a dry lubricant such as talc that allows the particles to move over each other without damage. The outer covering may consist of a single thick latex layer, a thin latex layer surrounded by a thick rubber layer or a number of thin latex layers. The semi-resiliency of the grip enables a user to deform the grip and thereby change its shape. The grip can be moved within the hand to allow the user to deform it repeatedly while changing the grip'"'"'s shape each time.

Claims

1. A semi-resilient exercise grip comprising:

a non-resilient, core, containing a deformable mixture of individual particles identical in size and shape to millet and a talc lubricant; and

a resilient covering surrounding said core wherein when the grip is held in a user'"'"'s hand in a non-deformed round shape and then compressed by a user'"'"'s hand, it is deformed into a first shape and upon the release of compressive force, the grip partially resumes the shape it had prior to the deformation and assumes a second shape.

2. The grip of claim 1 wherein the particles are tightly packed and are free to move within the core and the lubricant allows the particles to slide over each other without significant damage.

3. The grip of claim 1 wherein the particles are millet.

4. The grip of claim 1 wherein the lubricant is powdered talc.

5. The grip of claim 1 wherein the covering is formed from a plurality of rubber layers that are ball-shaped when in an unstretched state.

6. The grip of claim 5 wherein each rubber layer is formed from a latex rubber material.

7. A semi-resilient exercise grip consisting essentially of:

a core containing a deformable mixture of loose individual millet-sized and shaped particles and a dry talc lubricant; and

a resilient rubber covering surrounding said core wherein when the grip is held in a user'"'"'s hand in a non-deformed state, the grip has a round shape and wherein when the grip is compressed by a user'"'"'s hand, it deforms into a first shape and upon the release of compressive force, the grip partially resumes the shape it had prior to the deformation and assumes a second shape.

8. The grip of claim 7 wherein the rubber covering is composed of a plurality of latex sacks and wherein each sack has a round shape when in an unstretched state.
