Hockey Stick Blade Having Fiber-Reinforced High Density Foam Core

a fiber reinforced, foam core technology, applied in the field of hockey stick blades, can solve the problems of blades having mechanical properties that differ from each other, wood sticks and blades are relatively heavy, and are expensive to manufacture, so as to reduce the twisting of the blade, improve the response of handling and/or prevent the puck from flying.

Abstract

A composite hockey stick blade including a fiber reinforced, high-density foam polymeric core material overlaid with a plastic wrap. The fiber reinforcement material, in the form of a plurality of milled or long fibers, provides increased toughness and stiffness of the high density polymeric foam core material. The hockey stick blade may be utilized as a replacement blade for a two-piece hockey stick, or may be a portion of a one-piece hockey stick.

Description

TECHNICAL FIELD

[0001] The present invention relates generally to a hockey stick blade and, more particularly to, a hockey stick blade having a fiber reinforced high density foam core.BACKGROUND OF THE INVENTION

[0002] Typical current hockey stick blades or replacement blades are generally made of a core material reinforced with one or more layers of synthetic material, such as fiberglass, carbon fiber or graphite. Traditionally, the core of the blade has been made of natural materials, such as wood or a wood laminate. Traditional wood constructions, however, are expensive to manufacture due to the cost of wood and the manufacturing processes employed. Further, wood sticks and blades are relatively heavy and have somewhat limited durability. Finally, due to variabilities relating to wood construction and manufacturing techniques, wood sticks are difficult to manufacture with consistent tolerances, and even the same model and brand of sticks and blades may have differences in terms of ...

Embodiment Construction

[0015]Referring now to the FIGS. 1-2, a hockey blade 10 is depicted in accordance with a preferred embodiment of the present invention. It should be understood that while the preferred blade is intended for use in the sport of ice hockey, it can also be utilized in other sports, including roller hockey and field hockey. In general, the blade 10 comprises a hosel 12, a heel section 14, and a paddle (blade portion) 16. The heel section 14 is located at the junction of the hosel 12 and the paddle 16. The hosel 12 includes a tenon 18, or insert, adapted to be inserted into a hollow hockey stick shaft (not shown) made of aluminum, composite or graphite. It will be understood that the hockey stick shaft can be made of a variety of other materials, including but not limited to wood or wood laminate. The paddle 16 includes a front face 20 and a rear face 22 and further comprises a top edge 24, a tip region 26 and a bottom edge 28.

[0016]The blade 10, as shown in FIG. 2, is preferably formed ...
