Abstract A hockey stick is manufactured from a molded blade, a pultruded glass fiber shaft and a molded end cap. The interchangeable blade is made from a polycarbonate or wood. The shaft is hollow and made from glass fiber strips and rovings which are pulled through a heated die after being impregnated with a suitable resin to produce a shaft of rectangular section and of even wall thickness. The blade has a special tongue connection means on the supported end which snuggley fits into the end of the shaft and is adherred thereto by an adhesive such as an epoxy resin. The cap is cup-shaped and is preferably molded from a hard plastic and is adherred to the opposite end of the shaft from that supporting the blade to cover the end threreof. The cap could also be made from an elastomeric material to be frictionally retained in position over the shaft end. The use of the adhesive material makes certain that the cap will remain in place. Should the blade be damaged, chipped, broken or otherwise unuseable, it is sawed or otherwise separated from the end of the shaft and another blade has its tongue inserted into and adherred to the opposite end of the shaft after the cap was removed or had the top portion sawed or otherwise removed therefrom. Unique options are provided for the user of the hockey stick. The flexiblity of the shaft as well as the blade may be changed and the curvature of the blades may be changed which provides a further selection.
A method of constructing a hockey stick comprising: assembling four continuous fiberglass strips in such a manner as to form a rectangular cross sectionally shaped continuous hollow member defined by longitudinally extending opposing end walls and sidewalls; placing two spaced bundles of rovings along each sidewall of said rectangular shape and one bundle of rovings along each end wall of said rectangular shape; continuously pulling said fiberglass strips and said bundles of rovings through a heated die; pressure impregnating said fiberglass strips and said rovings with a resin while said rovings and said fiberglass strips are being pulled through said heated die so as to form a hollow elongated member of even wall thickness; severing shafts of predetermined length from said elongated member while continuing to pull said strips and bundles through said die; forming a hockey stick blade with an integral rectangular shaped elongated tongue portion of a cross sectional size smaller than the interior cross section of said shaft; providing an annular shoulder on said blade surrounding said tongue having a width equal to the width of the wall thickness of said shaft so as to blend smoothly therewith; providing recesses on opposite sides of said blade adjacent said tongue portion, said recesses being defined in part by reinforcing flange portions which act to reinforce said blade and by a portion of said annular shoulder; applying a layer of epoxy to said shaft interior and to said tongue portion; and inserting said tongue portion into one end of said hockey stick.
