Abstract
A hockey stick with a co-molded structure and method where the blade member is formed by a molding process onto a preformed shaft member, where the preformed shaft member has a contoured tip at the blade end. The contoured tip helps to secure the blade member to the shaft member in conjunction with the molded composite layers, and in one example, the contoured tip has a width that is greater than the width of the shaft member at the blade-starting region.
Claims20
A hockey stick apparatus, comprising:
- a shaft member comprising a toe side, a heel side, a butt end and a blade end;
- a blade member having a heel end, a toe end, and a striking face, wherein the blade member is integrally molded onto the shaft member;
- and
- wherein the blade end of the shaft member includes a contoured tip on the toe side, wherein the contoured tip has a maximum heel-to-toe width defined as a horizontal distance from the heel side of the shaft member to a peak of the contoured tip that is greater than a heel-to-toe width of the shaft member at a blade-starting region, wherein the heel-to-toe width at the blade-starting region is defined as a horizontal distance from the heel side of the shaft member to the toe side of the shaft member at the blade-starting region that is defined as a region on the shaft member where a plurality of prepreg layers that form the blade member onto the shaft member start on the shaft member.

A method of forming a hockey stick comprising:
- forming a shaft member by wrapping a plurality of prepreg layers around a mandrel to form a majority of the shaft member from a butt end to a blade end, wherein the blade end includes a contoured tip having a maximum heel-to-toe width defined as a horizontal distance from a heel side of the shaft member to a peak of the contoured tip on a toe side that is greater than a heel-to-toe width at a blade-starting region of the shaft member that is defined as the horizontal distance from the heel side of the shaft member to the toe side of the shaft member where a plurality of prepreg layers that form a blade member onto the shaft member start on the shaft member;
- wrapping a foam core of the blade member with a composite fabric to form a blade core;
- assembling the blade core adjacent the contoured tip of the shaft member;
- wrapping the plurality of prepreg layers around the blade core and the contoured tip of the shaft member forming a hockey stick assembly;
- placing the hockey stick assembly in a mold;
- heating the mold;
- and
- removing the hockey stick assembly from the mold.

- assembling a blade core adjacent the blade end of the shaft member;
- wrapping a plurality of prepreg layers around the blade core and the blade end of the shaft member to form a blade member of a hockey stick assembly;
- placing the hockey stick assembly in a mold;
- heating the mold;
- cooling the mold;
- and
- removing the hockey stick assembly from the mold.
