BACKGRO~JN~ OF T~E INVE~TION
1. Fielt of the In~ention The present in~ention relates generally to a hockey stic-k blade, and more partic~ rly, to a ~oller or ice hockey blade constructed of a plastic material and having a stru~re ~abling im~ t .l puck control.
2. l:~escrîption of the Prior Art Hockey stic~s have experieIlced dramatic ~hanges throughout the years.
For example, ice hockey s~cks have evolved from a plain ~rooden stick having a straight blade and handle to a signiff~ntly improved stick ha~ing a curved blateand bein$ ~ orced with fiber glass or the like. Sig~i~cAnt evolution has also 15 occurred in construction of the stick itself from sticks in which the ha~dle and blade portions were both const~ucted of wood and were joined with one another through various yro~s~ to forrn a single, integral unit, to sticks constructed of al~um or plastic and used wi~ re~lac~hle wooden blades.
Historically, wooden blades, whether i"~eE,l~lly joined with a wood 20 shaft and sold as a unit or sold separately as a repl~cP~nt blade with a plastic or aluminum shaft, were wrapped with friction or o~er tape. This helped tc ~r~,teelthe blade from wear as well as to provide the blade with a high frictional surface to enable the player to better control, pass and shoot the puck.
Hockey sticks have also evol~red fron~ being used exclusively in 25 connection wi~ the ga~e of ice hocke~ to being used for in-line roller or s~eet hockey utilizing a plasdc puck or ball. Because of this, some hockey stick manufacturers have begun producing co~ usite or plastic hocke~r sticks as well as composite or plastic Ieplacement blades. Although many of these plastic sticks and blades a~e intended primarily for use in in-line roller or street hockey, the~ also ~- 216~3~7 have applicability to ice hockey. These cu~ Yictin~ plastic blades are, for the most part, provided with a rela~dvely smooth hoe. Thus, the plastic repl~c~T-~ntblades currently on the market still need to be taped with fri~tion tape o~ the like in orde~ to provide the desi~ed ~rictional surface for controlling, passing, and gl~otir.g 5 the pucl~
Ac~r~ gly, there is a need in the art for a plas~c hG~-~ s~ck blade which Plimin~t~ the need for ~plJL.g the same with fric'don tape or the like, but yet still provides for the desired puck control.
SUMMAKY OF THE ~NVENTION
In cont~ast to d~e p~ior art, the present inven~on provides a plastic h:>~e~ stick blade whic~ can be formed il.leg~ y wi~ a plastic harldle or can beconstruc~ed as a repl~cPm~nt ~lade. ~he blade in accordance ~n~ the present invention includes a surface design which substantially simt-l~tPs a stick ~
15 w~th ,fric1;on tape. ~ccordingly, the p~esent i..v~,.l;on pro~ndes a plastic hockey stick blade ~Y~ihi1;~g puck cc1r.lf~ ' dble to that of a blade w~ d with f.~iction tape, ~nt~ollt the need to wrap ~e stick.
More spe~f;t ally~ the blade of the l,res~.~ v~Lion in~ltl~c a series of grooves formecl diagonally in ~e front and back faces of the blade. It ~as been found 20 that such stmcture provides a highly desirable fric~onal surface substanlially simulating that of friction tape ~4rapping for controlling, passing and shootin~ the puck. The blade of the present invention is also constr~lcted of a material w~ich provides the desired weight, toughness and rp~ enfy and which can be shaped, filed and curved to meet individual spefific~;o~.
P,e~æ~ably, ~e series of t;l~e~ extend from the toe end to the heel ent of the blade and extend from the top of ~e stic~ diagonally rearwardly toward the l~olLv~ Lably the series of ~;,ooves are sloped or angled relative to the boLLoi,.
of the blade at an angle less than 90 deg~ees.
- ~ 2~69~-~7 Accordingly, it is an object of the p~esent invention to pro~ide a plastic hockey ~tick blade ha~ing its front and back surfaces provided with a structure sim~ tin~ that of friction ta~e ~vra~ g.
Another object of t~e present invention is to provide a plastic hockey 5 stick blate which does not need to be wrapped with friction tape or the like, yet PY~ihite highly desirable p~lck control charactP~istics.
A~other object of the ~.es~l invention is to provide a plastic hockey sti~c blade either i.~L~ dlly formed with a plastic shaft or as a repl~mPrlt blade in which the front and rear faces have a series of spaoed E;roo~.es to simulate friction 10 tape wIap.

Figure 1 illu~.ltes a plastic hockey stick in~o,~ordli~.g the hockey stick blade 10 in acco~dance with ~e present invention. As shown, such Uade i~ d~s a blade portion 11 and a neck or shaft connec~on portion 12. Because the blade 10 of 5 Fig~lre 1 is shown as a repla~ ent blade, the outer end of ~e portion 12 is provided with a tenon 14 adapted for col~ne~i~-n with ~e hollo~ end o~ a repl~c~ n~nt shaft 15 in a m~ ~ known in the art. It should be noted that the blade of ~e ~r~.lt i,lvt:.~Lion can be provided eithe~ as a repl~Pm~nt blade as show~ in Pigure 1 or ~Itegl~lly joined ~th a sha~ simil~r to structures ~,o- .. in the art. As shown best in Pigures 4 and 5, the blade portion 11 includes a toe end 16, a heel end 18 and top 19 and l~otlu~l 20 edges. The cross sectional configuration of ~e blade portion 11 is Si~ilA- to ~at of hockey stick blades coIrunon in tihe art Thus, it is relatively ~in compaIed to its height and is substAnti~lly of equal tl~irl~nP~.s t-hro~lg~o~t, except at its edges. The blade portiorl 11 is also provided wi~ a front face 21 and a back or rear faoe 22 as shown in Figures 2, 4 and 5.
~ accordance ~i~ ~e present invention, both the front 21 and rear 22 faces are provited wi~ a series of spaoed ~;lCXS~S 24, or alternating ~;.oove~ 24 and ribs ~!6, P~n~irtg subst~ntiAlly from near the toe end 16 to the heel end 18 andeYt~nAin~ ~roughout the faces of the blade from 1 he top edge 19 to the botLoi~L edge 20. AS shown best in Pigures 1, 4 and 5, the g~GOv~ 24, or g~ou~ s 24 and ribs 26, extend ~iA~ ~n~11y relative to the top 19 and l~lLu~ 20 edges of ~e blade and ~efe~c.bly slope from the top edge 19 downwardly and re~ ~vardly toward the ~ol~o~.. edge 20 The speafic angle of slope "A" (Figure 5) of the gl~reS 24 relative to the top 19 and bottom 20 edges can v~y to some degree and s~ll ;~rfc~ . the 25 desired f~ n of eliminating the ~riction ~ape wrap and pro~ndin~ puck cor~trol.
Pf~fe,~bly, ho~ever, such angle "A" ~neasured rela~ve to ~he l~ollu.,. of the blade as defined by the base line "B" is less ~an 90 degrees. The base line "B" is a straight line forming a tangent approximately at the center of ff~e bo~to". edge 20. More - ~ ~169347 ~r~er~bly, an~le "~" is between about 30 and 85 degrees and most ~r~f~.~bly between 50 and 80 deg~ecs. The ~nost ~ef~able angle ~or t~he ~,,oo~es 24 is about 70 degrees relative to the base line "B"
Although the ~.ele~ied ernbodiment shows t}-e ~,~ves 24 as ~Yt~n~ing f~om the top edge 19 downwardly and re~ wa~dl~r ~oward ~e t~llo~. edge20 on bo~ the front 21 and rear 22 hces, it is contempla~ed *lat i~ r~,~. d fric~;o~

P.eferably, howetrer, the width of the groove WG is between about 030 and 090 inches and most ~ rerably about .060 inches, the width of the rib ~R (or ~e distance between the grooves 24) is ~rer~lbly bet~een about .070 and .130 inches and most ~rerelably about .10 inches and l:he height H of the rib (or depth of the groove) is be~ween about .020 and .060 inches deep and most ~re~rdbly about .040 inches deep.
