Abstract

Claims (21)

1. A hockey-stick blade including a front face and a rear face spaced from the front face in a lateral direction, and an upper blade edge and a lower blade edge, comprising:

a heel region;

a toe region spaced from the heel region in a longitudinal direction;

a mid-region located between the heel region and the toe region;

a first reinforcing element at a first vertical position in the toe region having a first length in the longitudinal direction, the first reinforcing element contained within the blade; and

a second reinforcing element at a second vertical position in the toe region having a second length in the longitudinal direction that is greater than the first length, the second reinforcing element contained within the blade and positioned closer to the lower blade edge than is the first reinforcing element.

2. The hockey-stick blade of claim 1 wherein the first and second reinforcing elements each comprise a pair of fiber-reinforced plies, with the first ply including fibers oriented at a positive angle, and the second ply including fibers oriented at an opposing negative angle.

3. The hockey-stick blade of claim 2 wherein the first ply includes fibers oriented at approximately 30° relative to a plane in the lateral direction, and the second ply includes fibers oriented at approximately −30° relative to the plane in the lateral direction.

4. The hockey-stick blade of claim 1 further comprising at least one rib between the front and rear faces running in the longitudinal direction from the toe region to at least the heel region.

5. The hockey-stick blade of claim 4 wherein the rib is integrally formed with the front and rear faces.

6. The hockey-stick blade of claim 1 further comprising a third reinforcing element at a third vertical position in the toe region having a third length in the longitudinal direction that is greater than the second length.

7. The hockey-stick blade of claim 1 wherein the toe region includes at least four reinforcing elements located at at least four separate vertical positions in the toe region.

8. The hockey-stick blade of claim 7 wherein the toe region includes six reinforcing elements located at six separate vertical positions in the toe region.

9. The hockey-stick blade of claim 1 wherein the blade includes a plurality of core elements wrapped in fiber-reinforced plies, wherein the reinforcing elements are positioned on exterior regions of the wrapped core elements.

10. The hockey-stick blade of claim 9 wherein the fiber-reinforced plies are arranged in pairs, with the first ply in each pair including fibers oriented at approximately 30° relative to a plane in the lateral direction, and the second ply in each pair including fibers oriented at approximately −30° relative to the plane in the lateral direction.

11. The hockey-stick blade of claim 1 further comprising a hosel attached to or integral with the heel section, wherein the hosel section includes a pair of fiber-reinforced plies, with the first ply including fibers oriented at approximately 90° relative to a plane in the lateral direction, and the second ply including fibers oriented at approximately 0° relative to the plane in the lateral direction.

12. A hockey-stick blade including a front face, and a rear face spaced from the front face in a lateral direction, comprising:

a heel region;

a toe region spaced from the heel region in a longitudinal direction;

a mid-region located between the heel region and the toe region; and

means for selectively stiffening the toe region such that a lower region of the toe region is stiffened to a greater extent than an upper region of the toe region, and such that the toe region is longitudinally stiffened to a greater extent than the mid-region and the heel region.
