Abstract
Abstract A hockey stick formed having a double-box beam shaft defining an elongated handle, and a molded laminated blade structure integrally molded to one end of the double-box beam shaft. The laminated blade is formed by molding a plastic core having laminated therein outer oppositely disposed preformed resin-impregnated web-like cloth sheets, and inner oppositely disposed unidirectional fiberglass-strip members positioned longitudinal of the main-body portion of the blade, the fiberglass strips being held in spaced relationship to each other by foam spacers, whereby a pair of elongated fiberglass rod members are interposed between a portion of the strips and the angularly disposed neck portion of the blade, and encapsulated within the plastic core, the rods extending outwardly to be integrally molded to the shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
An improved hockey stick comprising: a double-box beam shaft defining an elongated handle having a central strut wall forming contiguous box channels therein; a fabricated blade having a main blade-body portion and an angularly disposed integral neck portion; a pair of juxtaposed mainstays extending outwardly from said neck portion and formed as an integral part thereof, each of said mainstays being disposed and secured in said respective box channels of said shaft, whereby said shaft abuts against said neck portion; a pair of fiberglass rod members encapsulated within said neck portion of said blade and said respective mainstays, said rod members extending angularly upward from the lower contacting edge of said blade into said respective mainstays; wherein said fabricated blade further comprises: a core formed from a plastic resin; a webbed plastic cloth material embedded about the outer surface of said plastic resin core, defining a hard protective skin for said blade; a plurality of elongated layers of pulltruded unidirectional fiberglass strips laminated within said core and longitudinally disposed along said blade-body portion; and a plurality of resilient spacer members interposed between said strips to provide space between said strips, allowing said resin core to be received therein and thereby establishing a laminated blade body.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
47 words
A hockey stick as recited in claim 1, wherein said webbed plastic cloth material defines a pair of skin sheets having the overall configuration of said blade, defining a body section and a neck section to respectively correspond to said blade-body portion and to said neck portion.
Claim 4
Dependent Claim
31 words
A hockey stick as recited in claim 2, wherein said skin sheets are formed from a fiberglass material impregnated with plastic selected from the group consisting of epoxy, polyester and phenolic.
Claim 5
Dependent Claim
51 words
A hockey stick as recited in claim 3, wherein said blade is formed having a linearly curved body portion, the width of said body portion being tapered in a cross-sectional configuration, and the bottom longitudinal edge of said body portion being wider than the upper longitudinal edge of said body portion.
