Hockey stick blade with resiliently compressible core member
View Patent ↗A blade for a hockey stick includes a front face, a rear face, a first end operable to be connected to a blade connecting end of a handle portion, a second end that is opposite the first end, an upper edge that extends between the first and second ends, and a lower edge that extends between the first and second ends. The blade includes a resiliently compressible core member and a covering member that partially encases the resiliently compressible core member. The covering member defines an exterior surface of the blade and includes an opening on the lower edge of the blade that exposes the resiliently compressible core member.
1. A blade for a hockey stick, the blade including a front face, a rear face, a first end operable to be connected to a blade connecting end of a handle portion, a second end that is opposite the first end, an upper edge that extends between the first and second ends, and a lower edge that extends between the first and second ends, the blade comprising:
a resiliently compressible core member; and
a covering member that partially encases the resiliently compressible core member and that defines an exterior surface of the blade, the covering member including an opening on the lower edge of the blade that exposes the resiliently compressible core member;
wherein the opening is located only on the lower edge of the blade.
2. The blade of claim 1 , further comprising at least one rigid core member that is at least partially encased by the covering member.
3. The blade of claim 2 , wherein the at least one rigid core member includes a rigid foam.
4. The blade of claim 2 , further comprising a rib that is disposed between the at least one rigid core member and the resiliently compressible core member, the rib and the covering member being integrally connected, the rib extending between the front and rear faces.
5. The blade of claim 2 , wherein the resiliently compressible core member and the at least one rigid core member at least partially overlap between the front and rear faces.
6. The blade of claim 5 , wherein the resiliently compressible core member is disposed closer to the front face than the at least one rigid core member.
7. The blade of claim 2 , wherein the at least one rigid core member includes a first rigid core member and a second rigid core member, the first rigid core member overlapping the resiliently compressible core member and the second rigid core member between the upper and lower edges.
8. The blade of claim 1 , wherein the resiliently compressible member includes an elastomeric material.
9. The blade of claim 8 , wherein the elastomeric material is at least one of polyurethane, silicone, neoprene, and rubber.
10. The blade of claim 1 , wherein the covering member includes a plurality of woven carbon fibers that are embedded within a matrix material.
11. A blade for a hockey stick, the blade including a front face, a rear face, a first end operable to be connected to a blade connecting end of a handle portion, a second end that is opposite the first end, an upper edge that extends between the first and second ends, and a lower edge that extends between the first and second ends, the blade comprising:
a resiliently compressible core member; and
a covering member that partially encases the resiliently compressible core member and that defines an exterior surface of the blade, the covering member including an opening on the lower edge of the blade that exposes the resiliently compressible core member;
wherein the resiliently compressible core member includes a bottom rib and a front sheet, the bottom rib being exposed through the opening, the front sheet being adjacent the front face.
12. A method of manufacturing a blade for a hockey stick, the blade including a front face, a rear face, a first end operable to be connected to a blade connecting end of a handle portion, a second end that is opposite the first end, an upper edge that extends between the first and second ends, and a lower edge that extends between the first and second ends, the method comprising:
providing a resiliently compressible core member; and
partially encasing the resiliently compressible core member with a covering member to define an exterior surface of the blade, and to leave the resiliently compressible core member partially exposed through an opening in the covering member located only on the lower edge of the blade.
13. The method of claim 12 , further comprising providing at least one rigid core member, and at least partially encasing the at least one rigid core member with the covering member.
14. The method of claim 13 , wherein the at least one rigid core member includes a rigid foam.
15. The method of claim 12 , wherein the resiliently compressible core member includes a bottom rib and a front sheet, and wherein partially encasing the resiliently compressible core member includes exposing only a lower edge of the bottom rib through the opening.
16. The method of claim 12 , wherein the resiliently compressible member includes an elastomeric material.
17. The method of claim 16 , wherein the elastomeric material is at least one of polyurethane, silicone, neoprene, and rubber.
18. The method of claim 12 , wherein partially encasing the resiliently compressible core member includes wrapping a pre-preg of the covering member over the resiliently compressible core member and curing the pre-preg.
19. A hockey stick comprising:
a handle portion with a blade connecting end; and
a blade including a front face, a rear face, a first end operable to be connected to the blade connecting end of the handle portion, a second end that is opposite the first end, an upper edge that extends between the first and second ends, and a lower edge that extends between the first and second ends, the blade further including:
an elastomeric core member that includes a bottom rib and a front sheet, the bottom rib disposed adjacent the lower edge of the blade, and the front sheet adjacent to and extending along the front face of the blade,
at least one rigid foam member, and
a covering member that at least partially encases the at least one rigid foam member and the elastomeric core member, the covering member defining an exterior surface of the blade, the covering member including an opening on the lower edge of the blade that exposes the bottom rib of the elastomeric core member along the lower edge of the blade.
20. The blade of claim 1 wherein the covering member covers a first portion of the lower edge of the blade at said first end and a second portion of the lower edge of the blade at said second end such that said opening extends between said first and second portions.
