Abstract

Claims (42)

1. A ball bat comprising:

a barrel having a cavity therein, said barrel including a long axis and an inner diameter;

a generally disc-shaped support inserted inside said cavity, said support including an outer diameter less than said inner diameter, such that, as inserted, said support does not directly contact said barrel; and

a retaining member inserted inside said cavity, whereby said retaining member positions said support transverse to said long axis;

wherein said support is composed of a lightweight resilient material capable of resisting compression and fracturing during rolling and wherein said support is sized to not inhibit deformation of said ball bat when a batter uses said ball bat to strike a ball.

2. The ball bat of claim 1 , wherein said retaining member is cylindrical and sized to fit snugly within said cavity.

3. The ball bat of claim 2 , wherein said retaining member is adhered to said barrel with an adhesive.

4. The ball bat of claim 1 , wherein said support is one of a plurality of supports.

5. The ball bat of claim 1 , wherein said retaining member is one of a plurality of retaining members.

6. The ball bat of claim 5 , wherein said support is one of a plurality of supports and each of said plurality of retaining members positions one of said plurality of supports within said cavity.

7. The ball bat of claim 1 , wherein said support is composed of one of magnesium and graphite.

8. The ball bat of claim 1 , wherein structural characteristics of said support are selected to maximize structural integrity of said ball bat.

9. The ball bat of claim 1 , wherein said retaining member is composed of urethane foam.

10. The ball bat of claim 1 , wherein said support includes a hole.

11. The ball bat of claim 1 , wherein said barrel further comprises a sweet spot.

12. The ball bat of claim 11 , wherein said support is two supports positioned on either side of said sweet spot.

13. The ball bat of claim 11 , wherein said support is three supports: one support positioned at said sweet spot and one positioned on either side of said sweet spot.

14. The ball bat of claim 1 , further comprising a gap between said support and said barrel.

15. The ball bat of claim 1 , wherein said outer diameter of said support is about 95% of said inner diameter of said barrel.

16. The ball bat of claim 1 , wherein said outer diameter of said support is about 0.10 inches less than said inner diameter of said barrel.

17. The ball bat of claim 1 , wherein said retaining member is a non-circular geometric shape having at least three contact points for contacting said barrel.

18. The ball bat of claim 17 , wherein said support is affixed to said barrel via an adhesive.

19. The ball bat of claim 18 , wherein said retaining member includes a hole, and wherein said support includes a hole.

20. The ball bat of claim 18 , wherein said barrel further comprises a sweet spot.

21. The ball bat of claim 20 , wherein said support is two supports positioned on either side of said sweet spot.

22. The ball bat of claim 20 , wherein said support is three supports: one support positioned at said sweet spot and one positioned on either side of said sweet spot.

23. The ball bat of claim 18 , wherein said adhesive is one of urethane and silicone.

24. A ball bat comprising:

a barrel having a cavity therein, said barrel including a long axis and an inner diameter;

a generally disc-shaped support inserted inside said cavity, said support including an outer diameter less than said inner diameter, such that, as inserted, said support does not directly contact said barrel, and wherein said support is affixed to said barrel via an adhesive; and

a retaining member inserted inside said cavity, whereby said retaining member positions said support transverse to said long axis, said retaining member having a non-circular geometric shape having at least three contact points for contacting said barrel;

wherein said support is composed of a lightweight resilient material capable of resisting compression and fracturing during rolling, and wherein said adhesive is positioned such that it contacts said support and said barrel, but does not contact said retaining member.

25. A ball bat comprising:

a barrel having a cavity therein, said barrel including a long axis and an inner diameter;

a plurality of generally disc-shaped supports inserted inside said cavity, said supports each including an outer diameter less than said inner diameter, such that, as inserted, said supports do not directly contact said barrel; and

a retaining member inserted inside said cavity, whereby said retaining member positions said supports transverse to said long axis;

wherein said supports are composed of a lightweight resilient material capable of resisting compression and fracturing during rolling, and wherein said supports are one of: two supports positioned on either side of said sweet spot and three supports, one positioned at said sweet spot and one positioned on either side of said sweet spot.

26. A ball bat comprising:

a barrel having a cavity therein, said barrel including a long axis, an inner diameter, and a sweet spot;

a generally disc-shaped support inserted inside said cavity, said support including an outer diameter less than said inner diameter, such that, as inserted, said support does not directly contact said barrel; and

a retaining member inserted inside said cavity, whereby said retaining member positions said support transverse to said long axis, said retaining member having a triangular geometric shape having three contact points for contacting said barrel;

wherein said support is composed of a lightweight resilient material capable of resisting compression and fracturing during rolling.
