Abstract
A hockey stick having the appearance of a solid wood stick and superior handling properties is formed with an outer layer of resin-impregnated wood veneer formed integrally with an inner sheath of fiber-reinforced fabric and resin. In one embodiment of the hockey stick, the two outer layers are formed over a core which may be formed of foamed plastic core. In an alternative embodiment, the foam core extends through the handle area and the blade is formed of synthetic fibers overlaid and bonded to an outer wood veneer sheath by resin which impregnates both layers.
Claims15
A hockey stick comprising an elongated, generally rectangular handle and a shorter, thinner blade formed integrally with the handle at one end thereof and projecting with respect to the handle at an acute angle, the handle having a central core surrounded by an inner sheath of fiber-reinforced resin, which inner sheath is surrounded by a first outer sheath comprising a continuous elongated sheet of wood veneer having its length extending substantially parallel to the length of the handle and being shaped so as to extend over at least three faces of the handle, the sheet being impregnated with the resin and bonded to the inner sheath by said resin.
The method of forming a hockey stick having an outer surface comprising:
- molding a pair of elongated wood veneer preforms, each consisting of a complementary half of the outer surface of the finished stick;
- forming a central core having an outer surface;
- sheathing the entire outer surface of the core with fibrous reinforced fabric;
- impregnating the wood veneer preforms and the fibrous reinforcing fabric with liquid resin and bonding them together with the resin so that the wood veneer preforms sheath substantially the entire outer surface of the fabric.
A hockey stick comprising an elongated tube of fibrous reinforced fabric having an outer surface and a first sheath of wood veneer surrounding substantially the entire outer surface of the fibrous reinforced fabric tube, the sheath comprising a unitary elongated sheet of wood veneer having its length extending substantially parallel to the length of the tube, the tube and the wood veneer each being impregnated with and adhered to one another by resin.
