Abstract

A lacrosse racquet is formed with a unipartite and generally planar guard panel usefully formed as a moulded lattice structure from a suitable plastics material for interconnecting the toe and spine portions of the racquet frame. Such a guard panel avoids the problems due to sagging and bowing of woven guard structures and facilitates stringing. By forming the principal frame as a unitary moulded structure from a suitable plastic material, the lip portion of the racquet can be made much thinner than was previously possible thereby facilitating ''''scooping'''' the ball off the ground by the player.

PATENTED JUL 6 ISYI INVENTORS DANIEL R. CHO

- A TORNEY FRANKLIN MILLIGAN LACROSSE RACQUETS WITH PLASTIC GUARD PANEL The present invention relates generally to racquets for use in the game of lacrosse. v

Such a racquet is usually formed from a light staff of hickory wood, the end of which is bent to form a kind of hook. in the original racquets, a thong extended from the end of the hook to a point along the staff and the rounded triangle so fonned was woven with a loose net ting of gut or rawhide. It is also known to weave the netting in such a way that an upstanding guard strip. is formed below the thong to provide a ballcatching pocket along the racquet. Flexible gut spacers are often incorporated in such a guard strip to provide a more defined pocket.

It has, however, been recognized that such guard strips are unsatisfactory in that in time the spacers become deformed causing the top edge of the guard strip either to curl inwardly or to bow outwardly. It will be appreciated that such bending of the guard strip will alter the ball-catching area of the racquet and that, if the inward curling is excessive, there will even be a danger of a ball becoming trapped in the racquet during play. v

It has previously been suggested that this difficulty might be avoided by the incorporation of rigid spacer members in the guard strip. Such spacer members are frequently held in place by their end-engagement with the individual ends or strips of the netting. Obviously, if the netting sags during use, there is a danger that the ends of such spacer members might become disengaged from the netting. if, on the other hand, the netting is threaded through holes provided in the spacer members, the

stringing operation becomes much more complicated and time-consuming.

A further disadvantage of presently know racquets is that the thinness of the hook or lip portion at the forward end of such a racquet is limited by factors of strength. A charac-- teristic feature of the game of lacrosse is the speed at which it is played and to permit the pace of the game to be maximized, it is important that a player-can readily scoop" the ball up off the ground. This is partially true at the present tirne in view of the rapidly growing popularity of the indoor version of the game. For this reason, the thinnest possible lip portion is desirable in alacrosse racquet.

An object of the present invention is to provide an improved lacrosse racquet.

A more specific object of'the present invention is to provide a lacrosse racquet in which the guard does not sag or bow.

These and other objects are achieved in accordance with the invention by the provision of a lacrosse racquet comprising a frame in the general fonn of a 7" and having a handle portion, 'a wall-defining spine portion, a generally :p'lanor lip portion and a toe portion, said handle and spine portions meeting at 'a crotch, said 'lip portion extending transversely between said spine portion and said toe portion and being disposed with its major plane generally parallel to a principal plane of said racquet said toe portion-extending from said lip portion towards said handle portion,:a resilient, unipartite .and generally planar rguard panel having generally parallel upper and lower edges and being connected between said toe and spine portions with said lower edge thereof being disposed generally in the same plane as said lip portion and being secured to said spine portion in general proximity to said crotch, and netting strung between said 'spine and lip portions and 'to said guard panel generally along'said lower edge thereof. I

By such use of :a resilient unipartite guard panel, the danger of the guard bowing or saggingis-completely:avoided.iFurthermoreythis resu'ltis achieved without requiring 'a complex and time-consuming stringing operation. In fact, "the assembly of the racquetsoftheinvention is significantly more simple than that for those of the prior art. t

'By the use of a resilient :plastics material, the guard panel this purpose, both thermoplastic and thermosetting compositions' may used and such compositions may usefully contain reinforcing fillers such as glass fibers.-A wide range of such compositions may be used and the use herein of the expression plastics materials is intended to denote any of the known thermoplastic or therinosetting compositions presenting the desired combination of rigidity and resilience.

In accordance with a preferred feature of the present invention, the frame of the racquet is itself manufactured from a suitable high strength resilient plastics material. By the use of such a material and of a moulding technique, thelip portion of the racket may be made much thinner than was previously possible and, as previously explained, this facilitates the fscooping" of a ball off the ground by a player.

The invention will now be described merely by way of illustration with reference to the accompanying drawings in which:

FIG. I is a fragmentary of a lacrosse racquet in accordance with the invention with the netting omitted for the sake of clarity,

FIG. 2 is a partial top plan view of the racquet of FIG. 1 showing the handle of that racquet in part and in section, and

FIG. 3 is an enlarged elevation of the guard panel of the racquet of FIG. 1.

The racquet generally indicated at 10 in the drawings com prises a frame in the general form of a 7' and having a handle portion generally indicated at'l2, a wall-defining spine'portion 14, a thin generally planar lip portion 16 and a tow portion 18. It will be noted that the lip portion 16 extends transversely between the spine portion 14 and the toe portion 18 and extends towards the handle portion 12 to provide a scoop" surface 20. This surface .20 is efiective for use by a player for picking-up" the ball off the ground.

The area 22 at which the spine portion 14 meets the handle portion 12 is herein referred to as the crotch. A resilient unipartite guard panel of a moulded plastics material and generally indicated at 24 interconnects the toe portion 18 and the spine portion 14 being connected to the latter in general proximity to the crotch 22. y

Four lead straps 26 extend from the crotch 22 to the inner edge of the lip portion 16. Each of these straps 26 is secured to the lip portion 16 by first being passed through an opening 28 provided for this purpose in proximity to the inner edge of the lip portion 16. Each strap 26 is provided in a know manner at its forward end with two openings through which the-.strap'is threaded toform a loop 30about'the inner edge of the lip por- :tion 1 6. The other ends of the straps 26 are secured to the spine portion 114 by passing them through holes 32 provided therein for this purpose.

The/racquet is essentially completed by netting 34 strung between the spine portion 14 and the guard panel 24, being threaded-around the lead straps 26 .and through the holes 32 in the spine portion as well as around the lower member 36 of the :guard panel The guard panel 24 is itself secured to the frame by flexible ties or strings 38 passing through holes 40 a provided for this'purpose in the'spine portion Hand in the toe portion 18. Each end of the :guard panel 24 is secured by two such tiesISB to ,preventtwisting of the guard panel with respect to the netting 34.

As hereinbefore explained, the guard panel 24 may be formed of any suitable rigid 'but resilient material. Although the guard panel 124 iszshown in the drawings as having an open lattice structure, it will be appreciated that panels having other'configurationscan also be used.

The 'use of fiber-reinforced plastics materials 'for both the :guard panel 24 and the 'frame-zitself has already been mentioned. The use of such materials permits the manufacture of :the racquets by relatively inexpensive moulding operationsas well as enabling "the racquets to be made with the optimum angle :at the crotch 22 and with :the desirable thin lip portion 16.

The racquet shown 'in the drawings is also provided, as :is well known for existing .racquets, with astop guard 42 and 'a 'bracers'trap can readily be formed by moulding asauni-tary structure. For What'we claim asoursinvention is:

I. In a lacrosse racquet comprising a frame of resilient plastic material in the general form of a numeral 7 and including a handle portion, a wall defining spine portion of a substantially constant thickness, a generally planar lip portion and a toe portion, said lip portion being thinner than said spine and said toe portions, said handle and spine portions meeting at a crotch, said lip portion'extending transversely between said spine portion and said toe portion and being disposed with its major plane generally parallel to a principal plane of said racquet and said toe portion extending from said lip portion toward said handle portion, and netting strung between said spine and lip portions, a resilient, generally planar unitary guard panel of a resilient plastic material having generally parallel upper and lower edges being connected between said toe portion and said spine portion of said racquet with said lower edge thereof disposed generally in the same plane as said lip portion of said racquet, being secured to said spine portion in general proximity to said crotch, and having said netting secured therealong in general proximity to said lower edge thereof strung between said spine and lip portions and said guard panel.
