Abstract

A construct for a hockey stick blade and paddle structure having a spine that protrudes from a back face and provides structural rigidity, as well as recessed areas that reduce the mass of the paddle structure.

Claims

1. A hockey stick blade and paddle structure formed by a method comprising:

forming a first foam core of the blade;

wrapping the first foam core of the blade with a layer of fiber tape to form a wrapped blade core;

forming a front face and a back face of the paddle, coupled to a proximal end of the wrapped blade core, by layering fiber tape;

forming a spine by wrapping a mandrel with fiber tape;

forming first and second transition elements by wrapping first and second transition element foam cores with fiber tape;

positioning the spine on the back face;

positioning the first transition element at a proximal end of the back face of the paddle and the second transitional element at a distal end of the back face of the paddle;

wrapping the front face and the positioned spine and transition elements on the back face with fiber tape to form a wrapped paddle structure;

placing the wrapped blade core coupled to the wrapped paddle structure in a mold;

heating the mold;

cooling the mold; and

removing the mandrel from the spine and the formed hockey stick blade and paddle structure form the mold.

2. The hockey stick blade and paddle structure of claim 1, wherein the method further comprises:

positioning a plug element on the back face proximate the spine prior to heating the mold; and

removing the plug element from the back face following the cooling of the mold to reveal a recessed area.

3. The hockey stick blade and paddle structure of claim 1, wherein the mandrel comprises a silicone material.

4. The hockey stick blade and paddle structure of claim 1, wherein the spine comprises a hollow rectangular shaft.

5. The hockey stick blade and paddle structure of claim 1, wherein the spine comprises a hollow circular or semi-circular shaft.

6. The hockey stick blade and paddle structure of claim 1, wherein the spine comprises a hollow triangular shaft.

7. The hockey stick blade and paddle structure of claim 1, wherein the back face of the paddle has a first width and the spine has a second width, less than the first width.

8. A method of fabricating a formed hockey stick paddle structure, comprising:

forming a body of the paddle structure having a front face and a back face by layering fiber tape;

forming a spine by wrapping a mandrel with fiber tape;

forming first and second transition elements by wrapping first and second transition element foam cores with fiber tape;

positioning the spine on the back face;

positioning the first transition element at a proximal end of the back face of the paddle and the second transitional element at a distal end of the back face of the paddle;

placing the body of the paddle, the positioned spine, and first and second transition elements in a mold;

heating the mold;

cooling the mold; and

removing the mandrel from the spine.

9. The method of claim 8, wherein the method further comprises:

positioning a plug element on the back face proximate the spine prior to heating the mold; and

removing the plug element from the back face following the cooling of the mold to reveal a recessed area.

10. The method of claim 8, wherein the mandrel comprises a silicone material.

11. The method of claim 8, wherein the spine comprises a hollow rectangular shaft.

12. The method of claim 8, wherein the spine comprises a hollow circular or semi-circular shaft.

13. The method of claim 8, wherein the spine comprises a hollow triangular shaft.

14. The method of claim 8, wherein the back face of the paddle has a first width and the spine has a second width, less than the first width.

15. A method of fabricating a hockey stick apparatus comprising:

forming a shaft, having a proximal end and a distal end;

forming a blade, having a heel end and a toe end; and

forming a paddle comprising a top edge and a bottom edge, the paddle having a length extending between a proximal end and a distal end, and a first width extending between the top edge and the bottom edge, the distal end of the paddle coupled to the heel end of the blade, and the proximal end of the paddle coupled to the distal end of the shaft, the paddle further comprising;

a front face;

a back face, the back face further comprising;

a spine extending along a portion of the back face, the spine coupled to and protruding out from the back face, the spine having a second width less than the first width, a proximal end, and a distal end;

a stud, coupled to and protruding out from the back face; and

a recessed area, the recessed area having a first thickness,

wherein a second thickness of the paddle between the front face and a back surface of the spine is greater than the first thickness, and

wherein a third thickness of the paddle between the front face and a back surface of the stud is greater than the first thickness, and wherein the stud is at least partially surrounded by the recessed area.

16. The method of claim 15, wherein the spine comprises a rectangular shaft extending along a portion of the back face approximately parallel to a longitudinal axis of the paddle.

17. The method of claim 15, wherein the spine comprises a circular or semi-circular shaft extending along a portion of the back face approximately parallel to a longitudinal axis of the paddle.

18. The method of claim 15, wherein the spine comprises a triangular shaft extending along a portion of the back face approximately parallel to a longitudinal axis of the paddle.

19. The method of claim 15, wherein the spine comprises an I-beam shaft extending along a portion of the back face approximately parallel to a longitudinal axis of the paddle.

20. The method of claim 15, wherein the spine is at least partially hollow and has a cavity extending along at least a portion of the back face approximately parallel to a longitudinal axis of the paddle.
