Description
~20735~1D
This is a divisional of canadian patent application number 418,423 Eiled December 23, 1982.
This invention relates to improved ice hockey sticks such as used for playing the well-known game of ice hockey.
Ice Hockey sticks are normally made of hardwood and comprise an elongated handle of rectangular cross-section and a blade permanently secured at a given obtuse angle to the lower end of the handle by means of a suitable glued joint and of a wrapping of glass fiber in an epoxy resin.
The cost of hardwood handles and of reinforced hardwood handles becomes increasingly high on account of the limited supply of high quality hardwood suitable for this application and on accoun-t of the cost of labour and of raw material required for making wood laminates suitable as handle components, and the cost increases further when use is made of longi-tudinally ext~3nding reinforcing means such as rein-forciny strips to strengthen the handle of the finished product.
Various attempts have been made in the past in order to produce handles for ice hockey sticks which do not require the use of expensive wood, but hither-to these attempts failed to produce commercially successful products at competitive prices.
The primary object of the present invention is to produce a handle for an ice hockey stick of professional caliber which is commercially feasible and which may be mass produced at relatively low cost as compared to the cost of the handle components used for producing commercially acceptable hoc~ey sticks.
~2~735Q
In accordance with this invention, an ice hockey stick handle component is provided which is made of foam injected plastic material of suitable density having a filler member centrally located in the handle component and a reinforcing strip of unidirectional strands of fibers in a suitable bonding agent embedded centrally on each side of the handle component. The preferred foam plastic materials are poly-urethane, polyethylene and polypropylene.
The invention also provides a novel method of joining a handle component and a blade component which is suitable for use in connection with a foam injected reinforced handle component. In accordance with this novel joint, the handle component ~erminates at its lower end with a gradual taper on each side thereo and a complementary groove is made in the rear edge o the hardwood blade or permanently receiving and retaining by glue the tapered portion o the han~dle component.
The invention thereore provides a process or producin~ a foam injected plastic injected component and also a method of joining together such a plastic handle component and a conventional hardwood blade.
The invention also proposes to adapt the above-mentioned novel joint to the making of ice hoc~ey sticks using conventional hardwood handle components.
A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings wherein:
~:~0~7~35~
Figure 1 is a perspective view of an ice hockey stick made in accordance with this invention, Figure 2 is a partial perspective view of the upper end of a foam injected plastic handle component;
Figure 3 is a cross-sectional view taken alon~ line 3-3 of Figure l;
and Figure 4 is a perspective exploded view of a handle component showing a tapered end, and of a blade component showing a V-shaped groove in the rear edge thereof for receiving the tapered end of the handle component.
Referring now to the drawings, the ice hockey stick 10 shown in Figure 1 is made of an elongated rigid handle 12 ha~ing a tapered lower end portion 14, and a blade 16 permanently secured to the tapered end 14 of handle 12.
Handle component 12 is also visible in partial perspective view in Figure 2 and in cross sectional view in Figure 3.
It consists of an elongated body of foam injected plastic material ~0 filled with a longitudinally extending filler member 22 and, centrally on each side of handle component 12, a flush reinforcing strip 24,26 of unidirectional strands of .
fibers in a suitable bonding ag~nt. In cross~section, handle 12 is essentially rectangular and constant throughout its length except at its lower tapered end portion 14 where the two sides (one of which is shown at 29) gradually taper inwardly as illustrated in Figure 4. As in conventional ice hockey stick handle designs, handle 12 is chanfered on all four co~ners as shown at 30, which chanEers terminate at the start of the tapered end portion 14 as shown at 32 in Figure 4.
~07:~5~13 The cross-section of filler 22 is not critical to this invention nor is the type of material used therefor. In a preferred embodiment, filler 22 is an I-shaped solid piece of softwood whose main purpose is to reduce the amount of foam plastic material required for the manufacture of handle 12.
It also serves as a spacer during the manufacture of handle 12 as will be described below.
The presence of preformed reinforcing strips 24 and 26 ensures the re~uired degree of longitudinal rigidity of handle 12, and the exact dimensions of reinforcing strips 24 and 26 as well as their compositions are basically a question of design to suit the needs of the players. Nevertheless, reinforcing strips 24 and 26 ar~ preferably of constant rectangular cross-section and they are very thin as compared with the thickness of handle 12. They extend along the full len~th of the handle component and terminate just slightly inwardly of the corners 30. They also extend into the lower tapered end 14 and terminate at the thin bottom edge 36 which is at angle x with respect to the rear edge 38 of handle 12.
Angle x determines the approximate angular relationship ; between blade 16 and handle 12, which angular relationship varies slightly among the various models of ice hockey sticks offered to hockey players to suit their particular requirements as in well-known in the art.
The foam injected plastic material may be any suitable foamable plastic such as polyurethane, polyethylene and polypropylene and the shape of tapered end 14 i5 obtained in the moulding operation by so constructing the cavity of the mold used for this purpose.
120~35~
The process for making handle 12 uses the relatively well-known technique called rim molding which involves the use of a suitable mold (not shown) having any number of identical cavities whose shapes correspond to the desired shape of the finished handle component 12. The process involves placing in the bottom of the ~avity o~ the mold a reinforcing strip 24,26, placing filler 22 over the first strip, and placing a second reinforcing strip 24,26 over filler 22 after which the mold is closed and the plastic material is injected. Heat is then applied in order to effect curing and foaming of the plastic material and then the mold is opened and the handle component 12 is removed. The sides 29 of the tapered end portion 14 may be abraded slightly by sanding in order to remove all impurities and provide some degree of rugosity for better adhesion of glue, and ik is ready or the next operation.
Blade component 16 and handle 12 are then glued together using a strong glue such as epoxy resin or a suitable wood glue compàtible with foam plastic and the material of which reinforcing strips 24 and 26 are made.
Blade component 16 is made of hardwood whose grain extends in the longitudinal direction as illustrated by arrow 40.
A solid piece of hardwood may be used but it is preferred to use a series of strips of solid hardwood 41 to 46 extending longitudinally from end to end and glued together on their contiguous edges. It may taper in the longitudinal direction because the free end 47 of the finished product lO may be considerably thinner than its region 48 adjacent the joint.
1;2~7351D
The outline of the blade component 16 is generally rectangular except its rear edge 50 which is cut at an angle equal to angle "x of the tapered end 14 of handle component 12. A groove 52 is cut into rear edge 50 which conforms very closely to the shape of tapered end 14 of handle component 12. The depth of groove 52 is equal to the length of bottom edge 36 of handle component 12 dnd the inner walls of groove 52 are planar and strictly parallel to the mating surfaces of handle component 12. As a result, rear edge 38 of handle component 12 becomes flush with rear edge 50 of blade component 16 when tapered end 14 is glued in place into groove 52. Likewise, thin bottom edge 36 o~ tapered end ~4 of handle component 12 is flush with bottom edge 53 of blade component 16 when the two components 12 and 16 have been permanentaly glued together.
The next skep in the method o manufacture of ice hockey stick 10 involves cutting blade component 16 to the desired outline 55 illustrated by a dotted line in Figure 4 to produ~e the profile of the blade of the finished ice hockey stick 10. After that the blade portion is further sanded to reduce it to the finished thickness, and then it may be heated so as to curve it transversally after which reinforcement is applied by wrapping or applying glass fiber cloth which will be held in place by means of a coating of epoxy resin or other adequate coating which bonds together the fibers of the rein-orcing cloth as is well known in the art. The ice hockey stick 10 may then be printed with various grade and quality indications and ornamentation may be applied as is current in the trade.
~7350 Thus, the invention provides a method of joining together a handle component and a blade component which may be adapted for using a molded foam plastic handle component reinforced with rigid strips of strong fibers, but the same joint is also applicable to handle components made of hardwood either in the form of a solid piece of hardwood such as ash and white birch or in the orm of hardwood laminates, with or without reinforcing means such as reinforcing strips 24 and 26. In accordance with this novel joint, the blade is made of a piece of hardwood whose grain extends longitudinally of the blade from the tip thereof 47 to the front edge 59 of handle component 12 and over both sides 29 o tapered end 14.
The resultant joint has proved to be surpxisingly strong in spite of its simplicity and ease o manufacture, the only critical aspect of such a join~ being the close conformity between tapered end 14 of handl~ component 12 and groove 52 of blade component 16.
The material used for making preformed reinforcing strips 24,26 which are normally produced by pultrusion techniques comprise fibers of glass/ fibers of graphite or fibers of aramide or any combination thereof, suitably held toqether by an appropriate bonding agent such as epoxy resin.
The cross-section of filler member 22 shown in Figure 3 is I-shaped and this component is made of a solid piece of soft-wood on account of the fact that this material is cheap, light weight and easily available. Obviously other types of material could be used instead of softwood if such were available. Other configurations of filler can also be envisaged on account o~ the limited role played by this component and its only critical 1~07~S0 dimension is that which determines the distance between reinforcing strips 24 and 26 when placed in the cavity of the mold prior to injection of the plastic material in li~uid form. The dimension in question which, in the illustrated I-shaped embodiment of Figure 3, is the length of the transverse upper and lower bars 60 and 61 of I-shaped filler 22 must be sufficient to maintain proper distance between reinforcing strips 24 and 26 throu~hout the molding operation of handle component 22 in order to avoid, as much as possible, the presence o foam plastic on the outside of reinforcing strips 24 and 26 except i it was des.ired to completely cover these surfaces in which case a uniform covering would be required and particular care should be taken when so constructing a handle component. In principle, however, it i5 preferable to avoid the presence of such oam plastic over the surface of reinforcing strips 24 and 26 in order to produce a satisfactorily attractive finish product without the necessity of sanding the sides of the finished handle component. The outer surfaces of reinforcing strips 24 and 26 constitute a 20. proper surface for applying decorative means and written inscriptions such as the name of the manufacturer or its trade mark and the model designation of each particular class of ice hockey stick. Thus, it is best to ensure that in the finished product the reinforcing strips 24 and 26 are flush with the adjacent plastic material inwardly of chanfers 30 as shown at reference numeral 65 in Figures 2 and 3.
: It should be understood that the scope of the present invention is not intended to be limited to the specific preferred embodiment illustrated in the d.rawings and described above.
