Rib-reinforced hockey stick shaft and method of fabrication
View Patent ↗The invention relates to a hockey stick shaft having a cross-section and properties varying along a length thereof and to a method for fabrication thereof. The varying cross section defines selected regions of optimized grip for the hands of a player and of optimized rigidity and resistance in torsion of the shaft.
1. A shaft for a hockey stick, comprising at least one structural rib integrated in at least one surface thereof, said at least one rib running at least in one part of a length of said at least one surface, said at least one rib being selectively positioned and oriented according to target localized mechanical properties along a length of the shaft,
wherein the position of the at least one rib on said at least one surface is modified from a proximate end portion of the shaft to a central portion of the shaft, and further modified from the central portion of the shaft to a distal end portion of the shaft adjacent a blade mounting region of the hockey stick, said at least one rib flattening and having a spreading geometry in the distal end portion adjacent the blade mounting region of the hockey stick.
2. The shaft as recited in claim 1 , wherein a position of said at least one rib over a width of said at least one surface of the shaft is selectively varied.
3. A shaft for a hockey stick, comprising at least one structural rib integrated in at least one surface thereof, said at least one rib running at least in one part of a length of said at least one surface, said at least one rib being selectively positioned and oriented according to target localized mechanical properties along a length of the shaft, wherein the position of the at least one rib on said at least one surface is selectively positioned along the length of said at least one surface to enhance a resistance in flexion of the shaft between positions of two hands of a player holding the hockey stick, and has a flattened and spreading geometry in an end portion of the shaft adjacent a blade mounting region of the hockey stick to enhance a resistance to torsional rotation and to deflection effect.
4. The shaft as recited in claim 1 , wherein the at least one rib has a geometry varying along the length of said at least one surface.
5. The shaft as recited in claim 1 , wherein the cross section of the at least one rib is rectangular, at least in part along the length of said at least one surface of the shaft.
6. The shaft as recited in claim 1 , the shaft further comprising at least one of longitudinally oriented high tensile strength wires and fibers on at least parts of said at least one surface thereof.
7. The shaft as recited in claim 6 , wherein said at least one of longitudinally oriented high tensile strength wires and fibers are provided in opposite surfaces of the shaft.
8. The shaft as recited in claim 1 , the shaft further comprising on at least part of a surface thereof a surface finish.
9. A method for fabricating a shaft for a hockey stick, comprising the steps of:
selectively integrating and orienting at least one structural rib in at least one part of a length of at least one surface of the shaft according to target localized mechanical properties along a length of the shaft;
modifying a position of the at least one structural rib on the at least one surface from a proximate end portion of the shaft to a central portion of the shaft, and further modifying the position thereof from the central portion of the shaft to a distal end portion of the shaft adjacent a blade mounting region of the hockey stick; and
providing that the at least one rib flattens and has a spreading geometry in the distal end portion adjacent the blade mounting region of the hockey stick.
