Abstract

A blade for a hockey stick, having a body including an outer layer with an outer surface defining at least part of each of the impact surfaces of the body. A face member is made from a different material, has opposed inner and outer surfaces interconnected by a peripheral edge, and is embedded in the body such that the peripheral edge is in contact with the first material and at least a major part of the inner surface is in contact with the body. The outer surface of the face member defines part of the first impact surface. The outer surface of the face member is aligned with the outer surface of the outer layer adjacent the face member such that the first impact surface is continuous over a transition between the outer layer and the face member. A method for making a hockey stick blade is also discussed.

Claims

1. A blade for a hockey stick, comprising:

a body adapted to be connected to the proximal end of a shaft, the body defining spaced apart first and second outer impact surfaces, each of the impact surfaces having a heel portion proximate a shaft connection point and a toe portion spaced apart from the shaft connection point, the body including an outer layer having an outer surface defining at least part of each of the first and second impact surfaces of the body, the outer layer made of a first material, the first material being a composite material; and

a face member made from a second material different from the first material, the face member having opposed inner and outer surfaces interconnected by a peripheral edge, the face member overlaying and embedded in the body, the peripheral edge being in contact with the first material and at least a major part of the inner surface of the face member being in contact with the body of the blade, the outer surface of the face member defining part of the first impact surface of the body, the outer surface of the face member being aligned with the outer surface of the outer layer adjacent the face member such that the first impact surface of the body is continuous over a transition between the outer layer and the face member.

2. The blade as defined in claim 1, wherein an entirety or substantially the entirety of the inner surface of the face member is in contact with the body of the blade.

3. The blade as defined in claim 1, wherein the face member overlays and is embedded in the outer layer such that the peripheral edge and the at least major part of the inner surface are in contact with the first material

4. The blade as defined in claim 3, wherein an entirety or substantially the entirety of the inner surface of the face member is in contact with the first material.

5. The blade as defined in claim 1, wherein the second material is a metal.

6. The blade as defined in claim 1, wherein the blade has different rigidity in one or both of torsion and bending when compared to the body of the blade without the face member embedded therein.

7. The blade as defined in claim 1, wherein the second material is more resistant to cracks than the first material.

8. The blade as defined in claim 1, wherein the second material has increased vibration dampening properties when compared to the first material.

9. The blade as defined in claim 1, wherein the second material has an isotropic rigidity and the first material has non-isotropic rigidity.

10. The blade as defined in claim 1, wherein the face member extends longitudinally from the heel portion to the toe portion.

11. The blade as defined in claim 1, wherein the blade has an internal cavity surrounded by the outer layer, the cavity spanned by a plurality of spaced apart internal ribs extending longitudinally between the heel portion and the toe portion, the ribs interconnecting opposed inner surfaces of the outer layer, the face member overlays a portion of the body spanning across at least two internal ribs.

12. The blade as defined in claim 1, wherein the outer surface of the face member is smooth.

13. The blade as defined in claim 1, wherein the inner surface of the face member includes at least one protuberance, such that the face member has a varying thickness.

14. The blade as defined in claim 1, wherein the face member extends to at least one edge of the body.

15. The blade as defined in claim 1, further comprising a coating over the impact surfaces of the body.

16. A hockey stick comprising:

a shaft having a proximal end and a distal end opposite the proximal end; and

a blade as defined in claim 1 connected to the proximal end of the shaft.

17. A method for making a hockey stick blade, comprising:

positioning a face member over an outer surface of a layer of uncured composite material, the face member being made of a material different from the uncured composite material;

putting the face member and the outer surface of the layer of uncured composite material extending around the face member in contact with a blade-shaped mold surface; and

heating the uncured layer of composite material and applying pressure to the layer of uncured composite material against the mold surface until the face member is embedded in the layer of composite material and the composite material is cured, an outer surface of the cured composite material surrounding the face member being aligned with an outer surface of the face member to form a continuous surface.

18. The method as defined in claim 17, wherein positioning the face member over the outer surface includes applying an adhesive between the face member and the outer surface.

19. The method as defined in claim 17, wherein the layer of uncured composite material is wrapped around at least one bladder, and applying pressure is performed by inflating the at least one bladder.

20. The method as defined in claim 17, further comprising applying a coating over the cured composite material and face member.
