Abstract

A golf grip composed of multiple rubber compounds producing desirable properties within the golf grip.

First claim

We claim:

1. A golf grip, comprising:
an elongated tubular body having an exterior surface, an interior surface, a butt end, a tip end, a length from the butt end to the tip end, and the golf grip has an overall density;
wherein a point along the length has a cross-section having a cross-sectional area, an exterior cross-sectional radius having a minimum exterior cross-sectional radius, and an interior surface radius having a minimum interior surface radius;
wherein the cross-section includes a first region, and a second region, the first region extending outward from the interior surface a first region thickness that is constant around interior surface, and thereby defining the second region as the balance of the cross-section between the exterior surface and the first region, wherein the first region thickness is equal to one-half of a difference between the minimum exterior cross-sectional radius and the minimum interior surface radius;
wherein a first region average density is determined for a first region test volume bounded by the interior surface, the second region, the cross-section, and an offset cross-section that is parallel to the cross-section and 1 cm away from the cross-section;
wherein a second region average density is determined for a second region test volume bounded by the exterior surface, the first region, the cross-section, and the offset cross-section;
wherein the first region average density is less than 0.6 g/cc and is less than the second region average density; and
wherein the elongated tubular body is formed of at least a first inner layer, having a first layer thickness, a first layer density, and a first layer quantity of blowing agent, and a second outer layer, having second layer thickness and a second layer density, wherein the first layer density is different than the second layer density, wherein the first inner layer and the second outer layer consist of rubber compounds cross-linked together under heat and pressure.

2. The golf grip of claim 1 , wherein the overall density of the golf grip is at least 0.45-0.65 g/cc.

3. The golf grip of claim 2 , wherein the first region average density is less than 75% of the second region average density.

4. The golf grip of claim 3 , wherein the first layer thickness is different than the second layer thickness.

5. The golf grip of claim 1 , wherein the second region average density is at least 50% greater than the first region average density.

6. The golf grip of claim 5 , wherein the second region average density is no more than 300% greater than the first region average density.

7. The golf grip of claim 6 , wherein the second outer layer has a second layer quantity of blowing agent different than the first quantity of blowing agent.

8. The golf grip of claim 7 , wherein the first layer quantity of blowing agent is at least twice the second layer quantity of blowing agent.

9. The golf grip of claim 1 , wherein the first layer has a first layer hardness of at least 55 Shore A prior to compression molding, and the second layer has a second layer hardness prior to compression molding that is different than the first layer hardness.

10. The golf grip of claim 9 , wherein second layer hardness is less than the first layer hardness.

11. The golf grip of claim 3 , wherein the first region average density is less than 50% of the second region average density.

12. The golf grip of claim 1 , wherein the first region average density no greater than 0.6 g/cc and the second region average density is at least 0.8 g/cc.

13. The golf grip of claim 4 , wherein the first layer thickness is no greater than 3.0 mm, and the second layer thickness is no greater than 2.5 mm.

14. A golf grip, comprising:
an elongated tubular body having an exterior surface, an interior surface, a butt end, a tip end, a length from the butt end to the tip end, and the golf grip has an overall density of 0.45-0.65 g/cc;
wherein a point along the length has a cross-section having a cross-sectional area, an exterior cross-sectional radius having a minimum exterior cross-sectional radius, and an interior surface radius having a minimum interior surface radius;
wherein the cross-section includes a first region, and a second region, the first region extending outward from the interior surface a first region thickness that is constant around interior surface, and thereby defining the second region as the balance of the cross-section between the exterior surface and the first region, wherein the first region thickness is equal to one-half of a difference between the minimum exterior cross-sectional radius and the minimum interior surface radius;
wherein a first region average density is determined for a first region test volume bounded by the interior surface, the second region, the cross-section, and an offset cross-section that is parallel to the cross-section and 1 cm away from the cross-section;
wherein a second region average density is determined for a second region test volume bounded by the exterior surface, the first region, the cross-section, and the offset cross-section;
wherein the first region average density is less than the second region average density, and the first region average density is less than 0.6 g/cc; and
wherein the first region and the second region include rubber compounds with at least one rubber compound containing a blowing agent.

15. The golf grip of claim 14 , wherein the first region average density is less than 75% of the second region average density.

16. The golf grip of claim 15 , wherein the second region average density is 50-300% greater than the first region average density.

17. The golf grip of claim 16 , wherein the second region average density is at least 0.8 g/cc.

18. The golf grip of claim 17 , wherein the first region includes a first blowing agent at a first blowing agent quantity, and the second region includes a second blowing agent at a second blowing agent quantity that is different than the first blowing agent quantity.

19. A golf grip, comprising:
an elongated tubular body having an exterior surface, an interior surface, a butt end, a tip end, a length from the butt end to the tip end, and the golf grip has an overall density of 0.45-0.65 g/cc;
wherein a point along the length has a cross-section having a cross-sectional area, an exterior cross-sectional radius having a minimum exterior cross-sectional radius, and an interior surface radius having a minimum interior surface radius;
wherein the cross-section includes a first region, and a second region, the first region extending outward from the interior surface a first region thickness that is constant around interior surface, and thereby defining the second region as the balance of the cross-section between the exterior surface and the first region, wherein the first region thickness is equal to one-half of a difference between the minimum exterior cross-sectional radius and the minimum interior surface radius;
