Composite hockey stick system
View Patent ↗A handle end is adapted to be held by a player and a striking end is adapted to contact and propel an object. The stick includes a shaft coupling the handle end and the striking end. The shaft is fabricated of a relatively rigid material with limited flexibility. The shaft has a hole extending there through with a cylindrical wall defining the hole for varying the playing characteristics of the system.
1. A hockey stick comprising:
a shaft formed of two hollow tubes, each tube having a length, the tubes being coextensive and having facing surfaces along their length, wherein portions of said facing surfaces are fused together along fused portions to form an integral interior wall of the shaft, and wherein said tubes have non-facing surfaces which form external surfaces of the shaft, wherein the external surface of one tube adjoins the external surface of the other tube on opposite sides of said shaft to define a hollow interior of the shaft, and wherein said interior wall extends from adjoining external surfaces of said hollow tubes on one side of said shaft, through the hollow interior of the shaft, to adjoining exterior surfaces of said hollow tubes on an opposite side of said shaft;
wherein said facing surfaces are separated from one another at one or more locations between fused portions such that the walls of the facing surfaces at the separated locations define one or more apertures which extend through the shaft in a direction at least generally perpendicular to the longitudinal axis, the apertures being defined by separated, facing surfaces of the tubes, wherein said apertures are formed without forming holes through either tube; and
wherein the facing surfaces of the two or more tubes comprise a composite material including a plurality of fiber layers, the composite material extending continuously along said fused portions and the one or more locations at which the facing surfaces are separated to form one or more apertures; and
a striking end secured to one end of said shaft.
2. The hockey stick of claim 1 , wherein said shaft and said striking end are bonded to one another.
3. The hockey stick of claim 1 , wherein said shaft and said striking end are formed separately and joined mechanically.
4. The hockey stick of claim 1 , wherein said facing surfaces of said tubes are separated from one another at a plurality of locations along the length of the shaft so as to form multiple apertures through said shaft.
5. The hockey stick of claim 1 , wherein the striking end is selected from a group consisting of an ice hockey blade, a roller hockey blade, and a field hockey blade.
6. The hockey stick of claim 1 , wherein said striking end lies generally in a plane, and wherein said interior wall and said one or more apertures are oriented at least generally perpendicular to said plane.
7. The hockey stick of claim 1 , wherein each of said one or more apertures has an axis, and further wherein the axes of at least two apertures are parallel to one another.
8. The hockey stick of claim 1 , wherein said striking end comprises a blade extending at an angle relative to said shaft, and wherein said interior wall and said one or more apertures are oriented at least generally perpendicular to said blade.
9. A composite hockey stick comprising:
a shaft, having a longitudinal axis and being formed of two hollow tubes, each tube having a length, the tubes being coextensive and having facing surfaces along their length, wherein portions of said facing surfaces are fused together along fused portions to form an integral interior wall of the shaft, and wherein said tubes have non-facing surfaces which form external surfaces of the shaft, wherein the external surface of one tube adjoins the external surface of the other tube on opposite sides of said shaft to define a hollow interior of the shaft, and wherein said interior wall extends from adjoining external surfaces of said hollow tubes on one side of said shaft, through the hollow interior of the shaft, to adjoining exterior surfaces of said hollow tubes on an opposite side of said shaft;
wherein said facing surfaces are separated from one another at one or more locations between fused portions such that the walls of the facing surfaces at the separated locations define one or more apertures which extend through the shaft in a direction at least generally perpendicular to the longitudinal axis, the apertures being defined by separated, facing surfaces of the tubes, wherein said apertures are formed without forming holes through either tube;
wherein each tube is fabricated of multiple layers of reinforcing filaments held together with a resin binder, and wherein said shaft, in cross-section, has rectangular shape defined by the external surfaces of said tubes;
a striking end fabricated of multiple layers of reinforcing filaments held together with a resin binder, said striking end having a generally thin configuration with a first face, a second face, an upper edge, a lower edge, a near end, and a far end with the near end having a bend at an angle between 45 degrees and 80 degrees measured between the side faces of said shaft and the upper edge and the lower edge, said near end of said shaft having a connecting bar adapted to coupled into an opening in the bottom end of said shaft; and
an adhesive coupling the stick handle end with the stick striking end.
