Abstract

A vibration dampening grip cover for the handle of an implement is preferably of multilayer laminate form having an inner vibration dampening layer and an outer gripping layer. A further inner force dissipating stiffening layer is included in the laminate.

Claims (32)

1. A vibration absorbing grip cover for covering a handle of an implement comprising a premolded sleeve, said sleeve having an upper end and a lower end, said upper end being open to permit said sleeve to be inserted over and around the handle of the implement, said sleeve being made of an elastomeric vibration dampening material, said sleeve having a tacky outer surface to facilitate a user gripping the handle during use of the implement, and said lower end of said sleeve having an outwardly extending peripheral knob to act as a stop member for resisting the hand of a user from sliding off the handle during use of the implement.
2. The cover of claim 1 wherein the inner surface of said lower end of said sleeve is recessed having a contour conforming to the outer surface of said knob for fitting over a knob at the end of the implement handle.
3. The cover of claim 2 in combination with a baseball bat having a knob at one of its ends, and said cover being fitted over said baseball bat with said knob of said bat disposed in said knob of said cover.
4. The cover of claim 1 wherein the thickness of said sleeve at said lower end is greater than the thickness of said sleeve at the remaining portion of said sleeve.
5. The cover of claim 4 in combination with an implement having a handle, said handle terminating in an end which is free of any knob, and said sleeve being mounted over said handle.
6. The combination of claim 5 wherein said implement is an article of athletic equipment.
7. The combination of claim 6 wherein said implement is a tool.
8. The combination of claim 6 wherein said implement is a handlebar.
9. The cover of claim 1 wherein said sleeve is of single layer construction made from silicone material.
10. The cover of claim 1 wherein said sleeve is a multi-layer laminate, and said multilayer laminate including an inner layer of vibration absorbing material and an outermost layer of tacky gripping material.
11. The cover of claim 10 including a further inner layer made from force dissipating stiffening material.
12. The cover of claim 11 wherein said force dissipating material is an aramid material.
13. The cover of claim 12 wherein said aramid material is a layer in open mesh form.
14. The cover of claim 12 wherein said outer gripping layer is made of vibration absorbing material.
15. The cover of claim 1 wherein said sleeve tapers inwardly from said upper end to said lower end at the location of said knob.
16. In an implement having a handle with a gripping area, the improvement being in a vibration resistant cover over said gripping area, said cover being a multilayer laminate having at least an inner layer and an outer layer, said inner layer being made of an elastomeric vibration dampening material, and said outer layer being made of an elastomeric material having a tacky outer surface to facilitate the gripping of the handle.
17. The implement of claim 16 wherein said vibration dampening material is silicone, said outer layer being made of a thermoplastic material different than said inner layer, and said inner layer being thicker than said outer layer.
18. The implement of claim 16 including an intermediate force dissipating stiffening layer between said inner layer and said outer layer, said intermediate layer being made of an aramid material, and said intermediate layer being thinner than said inner layer.
19. The implement of claim 18 wherein said aramid layer is of open mesh form.
20. The implement of claim 16 including at least one further inner layer, and said at least one further inner layer being a thin layer made of force dissipating stiffening material.
21. The implement of claim 20 wherein said force dissipating stiffening material is an aramid material.
22. The implement of claim 21 wherein said aramid material is of mesh form.
23. The implement of claim 21 wherein said inner layer is made of silicone and is the innermost layer, said outer layer being made of a thermoplastic material, and said silicone layer being thicker than said thermoplastic outer layer.
24. The implement of claim 21 wherein said inner layer is made of a silicone gel and is the innermost layer, and said outer layer is made of a silicone gel.
25. The implement of claim 20 wherein said cover is applied over said gripping area in tape form.
26. The implement of claim 20 wherein said laminate includes at least four layers.
27. The implement of claim 20 wherein said implement is an article of athletic equipment.
28. The implement of claim 20 wherein said implement is a tool.
29. The implement of claim 20 wherein said implement is a handlebar.
30. The implement of claim 16 wherein said implement is an article of athletic equipment.
31. The implement of claim 16 wherein said implement is a tool.
32. The implement of claim 16 wherein said implement is a handlebar.
