Abstract
ABSTRACT OF THE DISCLOSURE
A hockey stick which is made of composite construction to use lower grade and lighter woods and which is characterized by not only preserving the usual advantages of the conventional hardwood stick but by also gaining in ease of construction in more balanced strength, in breaking resistance, and in the damping characteristics.
A hockey stick structurally characterized by comprising, in combination, a handle including a core of lower grade hardwood reinforced exclusively, on the opposite lateral sides respectively, by a pair of reinforcing layers each having stress resistant fibers extending lengthwise of the handle.

Description
~S~L6~3 This invention relates to hockey sticks.
The hockey sticks which are now manufaotured and used include a handle portion which iY made of solid wood selected from the best grad0 h~rd woods to obtain a product of desirable proparties and resistance to breakage. The co~t of a good hockey stick is therefore relatively high due to the inherent cost of a satisractory hard wood and, further~ore~ the hock~ stioks have to be made oversize to have a desirable resistance.
The applicant proposes a hockey stic~ including a handle portion of composite construction, which has the desired properties including rasistance to breakage and stiffness without necessarily uslng one of the best grade hard woods nor incraasing the cross-sectional area of the handle portion.
It is therefore a general ob~ect of the invention to provide a hockey stick of satisfactory properties without using one of the best grade hard wood~.
It is a more specifio ob~ect of the in~ention to provide a hockey stick having a handle portion of composite construction including reinforcement layers or strips adherad against the o M o~ite lateral ~ides theraof to increase the sti~fness and the resistance to breakage.

It is a more specifio ob~ect of the in~ention to provide a hockey stick having a handle portion of composite construction including reinforcement layers or strips adherad against the o M o~ite lateral ~ides theraof to increase the sti~fness and the resistance to breakage.
2~ ~t iB another ob~ect Or ths invention to provide a hockey stick inclu~ing a composite handle portion formed of a core oP wood material and reinforcing filaments adherad against the opposite lateral sides of tha core to impart stiffness and resistance to breakage to a wood of otherwise non-acceptable stiffne~s.
The above and other ob~ects and advantages of the invention will be bec~er understood in the light of the following detailed description of preferred embodiments which are illustrated, by way of example only, in the accompanying drawing~, wheruins Figure 1 is a side view of a hockey stick according to a first embodiment of the invention;
Figure 2 is a front view of the hockey stick shown in Figure 1;
Figure 3 is a cro~s-sectional view as seen along line 3-3 in Figura l;
Fi~ure 4 iB a cross-sectional view as show~ in Figure 3 of anothe~

Figure 7 i8 a perspective VieN of tne free end of a hoc~ey 6tick handle according to another embodiment of the invention; and Figures 8 and 9 are transvarse cross-sectional views of the handles of hoc~ey sticks according to di~ferent embodiments of the invention.
The hockey stick illustrated in Figures 1 and 2 include a blade portion 1, of ar~ conventional shape and material, such as the curved wooden blade now used by the hockey players. The blade is preferably reinforced with covering of glass fibre and plastics, as in conventional constructio~.
The hockey stick al80 includes a handle portion 2 having a core 3 of wood material and a psir of reinforcement layers or strips 4 secured against the opposite lateral side~ respectively of the core 3.
In the embodiment of Figures 1, 2, 3, 5, and 6, the relnforcement strips 4 are formed of a fabric woven with glass fibre filaments 5 extending len~thwise of the handle portion and embedded into a lsyer of plsstica. A band 6, of plastics or elastic material and of a suitable color, surrounds the handle portion over the ~oint between the lower end of the reinforcement strips 4 and the oonver,tional glass fibre and plastic covering of the blade portion 1. Band 6 serves to hide said ~oint and to decorate the hockey stick.
~s shown in Figure 4, the reinforcement ~trips 4 on the opposite sides of core 3 are formed o~ a single strip 7 bent tightly around the free end of the handle portion and temporarily retained in tension at its opposite ends by small nails, tacks 8, staples or the like. The strip 7 is glued against the core 3 for adhesion thereto. The strip 7 includes gla~s fibres which sxtend lengthwise of the handle portion or core 3 and woven into a ~abric. After trip 7 firmly adheres to core 3 tacks 8 are removed and the outer end Gf the handle portion is .inished as shown in Fi~ure 5, whera~n the folded portion of strip 7 has been . . . . .. . ... . .. . . .... .. . . . . . .. .... . . .
5 ~.6~33 removed and the ed~es of the handla have been bevelled.
Aocording to another embodirr,ent of the inventior., a~ shown in Fi~ures 7 ~nd 8J the handle portion may include a cora 9 havirg groov~s lG extending lengthwise and into the,opposite lateral sides the~eof. A
numoer of glass fibres or glass filaments 11 are bunched into each groove 10 and run lengthwise thereof ~mbedded into a plastic which i8 adhered to ths cora 9.
In the embodirnent illustratod in Figure 9, a series of glass filaments 11 extend 3ide by side and are embedded into a plastic forming fl~t strips adhered against the opposite lateral sides of the handle ~ortion.
It rnust be noted that the glass fibre filaments 5 and 11 ma~ prestressed &nd retained in that condition within the plastics in whlch they are embedded.
The filaments of gla3~ fibres may also be embodied into a sleeve fitting tightly over the free end of the core 8 or 9 defining the h~ldle portion.
DLe to the stiffness imparted by the reinforcement layQrs or strips, the core of tho h~ndle portion may be made of wood material ~elected from lower grade hard woods in~tead of the best hard woods as s now th~ practlca. FurthermoreJ laminated wood or plywood may be use~
.l5 well as a solid core.
From the results of testa carried out with sticks of different constructions, a hockey stick according to the present invention achieves a still better resistance to bre~kage than a conventional overaize stick ~ade of a best grade o~ wood. The oversize hockey sticks may therefore be advantageously replacad by hockey sticks according to the present invent on. I
It has bean discovered, for i~stance, that the ra~in wood ~o is particularly suitable to make the core of'the handle portion of a hockey stic~, according to the lig`n~ness~ rigidity and undistorting propertiss of that wood importsd from the East~
~ series of t~ts hav~ b~en carried out with ~lass fibre reinforGed hockey sticks havin~ a core of ramin wood and the rasults indicate a sharp improvement ~n the resistance to hreakage as co~pared to hocksy sticks having no glass f~bre reinforcement.
In accordance with the invention, types of stress resistin~
filaments could be used other than glass fibres~ For instancs, ~ilament~
of carbon fibres alone or mixed with glass fibres could be used to adv~ntage due to the very high tensile strength and stiffness modulus of graphite fibres.
