LACROSSE RACQUETS WITH PLASTIC GUARD PANEL
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.

Claims
What we claim as our invention is:
1. 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.
2. In a lacrosse racquet as claimed in claim 1, said guard panel
being in the form of an open lattice structure detachably secured
at each end thereof to said toe and spine portions by at least two
flexible ties passing through said lattice structure and through
openings provided for this purpose in said toe and spine portions.
Description
The present invention relates generally to racquets for use in the
game of lacrosse.
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 formed was woven
with a loose netting 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 ball-catching 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.
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 characteristic 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 time 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 a lacrosse
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 form of a "7" and having a handle portion, a
wall-defining spine portion, a generally planor 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 guard 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.
By such use of a resilient unipartite guard panel, the danger of
the guard bowing or sagging is completely avoided. Furthermore,
this result is achieved without requiring a complex and
time-consuming stringing operation. In fact, the assembly of the
racquets of the invention is significantly more simple than that
for those of the prior art.
By the use of a resilient plastics material, the guard panel can
readily be formed by moulding as a unitary structure. For 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 thermosetting
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, the lip portion of the racket
may be made much thinner than was previously possible and, as
previously explained, this facilitates the "scooping" 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. 1 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 comprises a
frame in the general form of a 7 and having a handle portion
generally indicated at 12, 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 effective 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.
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 to form a loop 30
about the inner edge of the lip portion 16. The other ends of the
straps 26 are secured to the spine portion 14 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 14
as well as around the lower member 36 of the guard panel 24. The
guard panel 24 is itself secured to the frame by flexible ties or
strings 38 passing through holes 40 provided for this purpose in
the spine portion 14 and in the toe portion 18. Each end of the
guard panel 24 is secured by two such ties 38 to prevent twisting
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 24
is shown in the drawings as having an open lattice structure, it
will be appreciated that panels having other configurations can
also be used.
The use of fiber-reinforced plastics materials for both the guard
panel 24 and the frame itself has already been mentioned. The use
of such materials permits the manufacture of the racquets by
relatively inexpensive moulding operations as 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 a stop guard 42 and a brace strap
44.
