Abstract

A two-part hockey stick having a hockey stick blade and a hockey stick shaft joined together at a joint. The hockey stick has a blade with a neck, a heel, and a toe. The joint has a male joint portion on an end of the shaft, which has heel and opposed toe walls, each of which extend away from a distal surface of the shaft and terminate at a mating surface. The heel wall is disposed on a side of the joint adjacent to a heel of the blade, and is longer than the toe wall. The mating surface extends between the heel and toe walls. The joint also has a hollow female joint portion disposed in a neck of the blade. The male joint portion mates with the female joint portion, thereby joining the shaft to the blade and forming the hockey stick.

Claims

1. A hockey stick, comprising:

a blade extending between a neck and a toe, and defining a heel, the neck having a neck rim circumscribing a neck opening which defines a female joint portion disposed within the neck; and

a shaft having a body extending between a grip end and an opposed blade end terminating at a distal surface, a male joint portion disposed at the blade end and mating with the female joint portion of the blade, the male joint portion having a heel wall on a first side of the male joint portion adjacent to the heel of the blade and a toe wall on a second side of the male joint portion opposite the heel wall, the heel wall extending away from the distal surface a first length and the toe wall extending away from the distal surface a second length, the first length being greater than the second length, the heel and toe walls terminating at a common mating surface extending between the heel and toe walls.

2. The hockey stick according to claim 1, wherein the mating surface is curved and protrudes convexly away from the blade end of the body of the shaft.

3. The hockey stick according to claim 1, wherein the male joint portion has an interior cavity defined between internal surfaces of the heel wall and the toe wall, and one or more reinforcement ribs being disposed within the interior cavity.

4. The hockey stick according to claim 3, wherein the one or more reinforcement ribs are substantially parallel to the heel wall and the toe wall and extend from the distal surface to the mating surface.

5. The hockey stick according to claim 4, wherein the one or more reinforcement ribs are equally spaced apart between the heel wall and the toe wall.

6. The hockey stick according to claim 1, wherein the mating surface defines a curved abutting surface adapted to abut one or more surfaces within the blade.

7. The hockey stick according to claim 1, wherein the blade has a front surface and an opposed rear surface, each of the front and rear surfaces extending from the neck to the toe and defining an interior blade cavity, and at least one blade rib disposed within the blade cavity and extending between the front and rear surfaces.

8. The hockey stick according to claim 7, wherein the at least one blade rib is substantially U-shaped and extends from a first end disposed in the neck, to the toe, along a length of an edge of the toe, and back to a second end disposed in the neck.

9. The hockey stick according to claim 8, wherein the first and second ends of the at least one blade rib abut against the mating surface.

10. The hockey stick according to claim 9, wherein the male joint portion has at least one joint rib extending from a first extremity at the distal surface to a second extremity at the mating surface, the second extremity being disposed between the first and second ends of the at least one blade rib abutted against the mating surface.

11. The hockey stick according to claim 1, wherein each of the toe and heel walls of the male joint portion abut against corresponding internal walls of the neck of the blade.

12. The hockey stick according to claim 1, wherein the body of the shaft is hollow and has a body cavity.

13. The hockey stick according to claim 12, wherein the body has at least one longitudinal shaft rib disposed within the body cavity and extending parallel to a length of the body between the grip end and the blade end.

14. A hockey stick shaft, comprising a body extending between a grip end and an opposed blade end terminating at a distal surface, and a male joint portion protruding from the distal surface and adapted to mate with a corresponding female joint portion of a hockey stick blade, the male joint portion having a heel wall extending from the distal surface a first length and an opposed toe wall extending from the distal surface a second length, the first length being greater than the second length such that the heel wall of the male joint portion extends further than the opposed toe wall, the heel and toe walls terminating at a common remote end surface, the heel wall disposed on a side of the male joint portion adjacent to a heel of the blade upon mating insertion of the male joint portion into the female joint portion, and the remote end surface extending between the heel and toe walls.

15. The hockey stick shaft according to claim 14, wherein the remote end surface is curved and protrudes convexly away from the blade end of the body of the shaft.

16. The hockey stick shaft according to claim 14, wherein the male joint portion has an interior cavity defined between internal surfaces of the heel wall and the toe wall, and one or more reinforcement ribs being disposed within the interior cavity.

17. The hockey stick shaft according to claim 16, wherein the one or more reinforcement ribs are substantially parallel to the heel wall and the toe wall and extend from the distal surface to the remote end surface.

18. The hockey stick shaft according to claim 17, wherein the one or more reinforcement ribs are equally spaced apart between the heel wall and the toe wall.

19. The hockey stick shaft according to claim 14, wherein the remote end surface defines a curved abutting surface adapted to abut one or more surfaces within the blade.

20. A hockey stick blade, comprising a blade body extending between a neck and a toe, and defining a heel, the neck having a neck opening circumscribing a female joint portion disposed within the neck and adapted to receive a corresponding male joint portion of a hockey stick shaft, the blade body having opposed front and rear surfaces defining an interior blade cavity and a substantially U-shaped blade rib disposed within the blade cavity and extending from a first end disposed in the neck, to the toe, along a length of an edge of the toe, and back to a second end disposed in the neck, the first and second ends of the blade rib abutting against the male joint portion upon being received in the female joint portion.
