Abstract
Abstract The present invention is a warm-up weight for softball bats that includes an open-ended cylindrical, tubular section integrally connected to a conical, tubular section. The conical section may be wedged against a tapering portion of a softball bat while the cylindrical section extends over a hitting, cylindrical, barrel portion of the softball bat. The cylindrical section includes an inner leaf spring cantilevered toward the open end of the cylindrical section.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A warm-up weight for a standard softball bat, the softball bat including a conical section defining a proximate handle portion and a cylindrical section defining a distal ball hitting portion, the warm-up weight comprising: a) a hollow open-ended cylindrical elongate integral section having an inner surface for extending over, conforming to, and bearing against the cylindrical portion of the softball bat, a leaf spring member having an end affixed to said inner surface, said spring member having a free end extending away from said inner surface and directed toward one end of said cylindrical section; b) a hollow conical elongate integral section attached to the other end of said cylindrical section for fitting over and being wedged against the conical section of the softball bat, said conical section being integrally connected to said cylindrical section to provide a removable warm-up weight.
Claim 2
Dependent Claim
141 words
A warm-up weight for a standard softball bat, the softball bat including a conical section defining a proximate handle portion and a cylindrical section defining a distal ball hitting portion, the warm-up weight comprising: a) a hollow open-ended cylindrical elongate integral section having an inner surface for extending over, conforming to, and bearing against the cylindrical portion of the softball bat, a leaf spring member having an end affixed to said inner surface, said spring member having a free end extending away from said inner surface and directed toward one end of said cylindrical section; b) a hollow conical elongate integral section attached to the other end of said cylindrical section for fitting over and being wedged against the conical section of the softball bat, said conical section being integrally connected to said cylindrical section to provide a removable warm-up weight.
Claim 3
Dependent Claim
148 words
A warm-up weight for a standard softball bat, the softball bat including a conical section defining a proximate handle portion and a cylindrical section defining a distal hitting portion having a distal end, the warm-up weight comprising: a) a hollow cylindrical elongate integral section for extending over, conforming to, and bearing against the cylindrical section of the softball bat, said cylindrical section having an open distal end, b) a conical elongate integral section for fitting over and being wedged against the conical portion of the softball bat, said conical section being integrally, connected to one end of said cylindrical section to provide a removable warm-up weight, and c) a safety member affixed to the inner surface of said cylindrical section intermediate the ends thereof for preventing the complete insertion of said distal end of the bat through the entire length of said cylindrical section of said warm-up weight.
Claim 4
Dependent Claim
148 words
A warm-up weight for a standard softball bat, the softball bat including a conical section defining a proximate handle portion and a cylindrical section defining a distal hitting portion having a distal end, the warm-up weight comprising: a) a hollow cylindrical elongate integral section for extending over, conforming to, and bearing against the cylindrical section of the softball bat, said cylindrical section having an open distal end, b) a conical elongate integral section for fitting over and being wedged against the conical portion of the softball bat, said conical section being integrally, connected to one end of said cylindrical section to provide a removable warm-up weight, and c) a safety member affixed to the inner surface of said cylindrical section intermediate the ends thereof for preventing the complete insertion of said distal end of the bat through the entire length of said cylindrical section of said warm-up weight.
Claim 5
Dependent Claim
53 words
The warm-up weight of claim 2, wherein said safety member extends generally and sufficiently toward the central axis of said cylindrical section a predetermined distance to prevent the insertion of said distal end of the bat into said cylindrical section if said distal end is attempted to be inserted before said handle portion.
Claim 6
Dependent Claim
15 words
The warm-up weight of claim 2, wherein said safety member is an elongated leaf-spring member.
Claim 7
Dependent Claim
15 words
The warm-up weight of claim 3, wherein said safety member is an elongated leaf-spring member.
Claim 8
Dependent Claim
21 words
The warm-up weight of claim 2, wherein an annular boss is integrally connected to the smaller end of said conical section.
