Abstract
Abstract A reinforcing member is provided within the handle portion of a wooden bat to prevent the heavy barrel portion from separating from the handle and flying through the air with possible injury to onlookers in the event of bat breakage upon impact with a ball. The reinforcing member is of less stiffness than is the wood of the bat so as to not change the flexing characteristics of the bat and is of small diameter and low specific gravity so as to avoid noticeable change in the weight and balance of the bat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A bat turned from a single piece of wood having a barrel portion of one diameter, a handle portion of a smaller diameter, a tapered portion intermediate the handle and barrel, and a reinforcing member; said reinforcing member comprising a high tensile strength, flexible rod having less stiffness than the wood from which the bat is fabricated and disposed within the bat longitudinally along the axis of the bat from the handle portion and extending into said tapered portion but terminating short of the barrel portion of said bat, the surface of said reinforcing member being bonded to said bat over the entire length of said member.
Claim 2
Dependent Claim
107 words
A bat turned from a single piece of wood having a barrel portion of one diameter, a handle portion of a smaller diameter, a tapered portion intermediate the handle and barrel, and a reinforcing member; said reinforcing member comprising a high tensile strength, flexible rod having less stiffness than the wood from which the bat is fabricated and disposed within the bat longitudinally along the axis of the bat from the handle portion and extending into said tapered portion but terminating short of the barrel portion of said bat, the surface of said reinforcing member being bonded to said bat over the entire length of said member.
Claim 3
Dependent Claim
22 words
The bat of claim 1 wherein said reinforcing member comprises a composite of generally parallel, high strength fibers in a polymer matrix.
Claim 4
Dependent Claim
11 words
The bat of claim 2 wherein said fibers are carbon fibers.
Claim 5
Dependent Claim
21 words
The bat of claim 1 wherein said reinforcing member comprises a drawn, small diameter rod of a high tensile strength polymer.
Claim 6
Dependent Claim
10 words
The bat of claim 4 wherein said polymer is nylon.
Claim 7
Dependent Claim
10 words
The bat of claim 4 wherein said polymer is polypropylene.
Claim 8
Dependent Claim
36 words
The bat of claim 1 wherein said reinforcing member extends to a point within the bat about the midpoint of said tapered portion and is a carbon fiber composite having a diameter of about one-eighth inch.
Claim 9
Dependent Claim
57 words
The bat of claim 1 wherein the handle portion of said bat terminates in an integral knob forming a bat end, wherein said reinforcing member stops short of the bat end, and wherein a circular recess is formed in the knob end, said recess being closed with a plug which covers an end of said reinforcing member.
Claim 10
Dependent Claim
21 words
The bat of claim 1 wherein said reinforcing member is constructed of a material having a specific gravity less than 2.5.
