Shaft for a sports stick such as a hockey stick
View Patent ↗A handle is adapted to be held by a player and a striking end is adapted to contact and propel an object A structure for a hockey stick is described by using multiple composite tubes bonded to one another, wherein apertures, or “ports,” are molded between the tubes to improve the stiffness, strength, aerodynamics and comfort of the hockey stick.
1. A shaft for a sports stick, comprising 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.
2. The sports 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.
3. The sports stick of claim 2 , 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.
4. The sports stick of claim 1 , wherein said shaft further includes a third tube of composite material disposed around, and bonded to, said exterior surfaces.
5. A hockey stick comprising:
a shaft formed of four hollow tubes, each tube having a length, the tubes being coextensive;
wherein each tube has a pair of facing surfaces along its length, wherein portions of said facing surfaces of each tube are fused together along fused portions with corresponding portions of facing surfaces of two other tubes to form integral interior walls of the shaft, and wherein said tubes have non-facing surfaces which form external surfaces of the shaft, wherein the external surface of each tube adjoins the external surface of two other tubes to define a hollow interior of the shaft, and wherein said interior walls extend 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 at least two of 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 the tubes; and wherein the facing surfaces of the 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.
6. The hockey stick of claim 5 , wherein portions of said facing surfaces are separated from one another at a plurality of locations along the length of the shaft so as to form multiple apertures extending through said shaft at an angle generally perpendicular to the longitudinal axis.
7. The hockey stick of claim 5 , wherein portions of said facing surfaces of all four tubes are separated from one another at the same axial location of said shaft to form a pair of apertures through the shaft which are perpendicular to one another.
