Description
FIELD OF THE INVENTION
[0001] The present invention relates to lacrosse head and, more
particularly, to a lacrosse head having an improved mechanism to
attach to a lacrosse shaft allowing a player's hand to grip the
shaft closer to a ball rest.
BACKGROUND OF THE INVENTION
[0002] Conventional lacrosse sticks today comprise a tubular metal
shaft and a molded high density composite plastic head. The tubular
metal shaft and head arrangement has been in existence since at
least the mid 1970's, see for example, U.S. Pat. No. 4,037,841,
title LACROSSE STICK HAVING TUBULAR METALLIC HANDLE, issued Jul.
26, 1977, incorporated herein by reference. FIG. 1 shows a
conventional lacrosse stick 100 having a conventional metal shaft
102 and a conventional head 104. Shaft 102 further has a butt end
106 and a head end 108. Head 104 further has a base 110, divergent
sidewalls 112, and a lip 114.
[0003] Extending from base 110 is a shaft junction projection 116
that comprises a female socket 118. Shaft junction projection 116
is a length d1. Head end 108 of shaft has a corresponding head
junction projection 120 that comprises a male plug 122. Male plug
122 is shown as having a cross-section consistent with the
remainder of metal shaft 102, but some conventional shafts have a
male plug 122 with a reduced cross-section. Head junction
projection 120 has a length d2, which typically is consistent with
length d1. Frequently, shaft 102 and head 104 are secured using a
pin or screw extending through both the shaft and head and secured
using another pin or nut, not specifically shown but generally
known in the art.
[0004] While the conventional shaft/head connection works, it has
several drawbacks. One major drawback is that shaft junction
projection 116 is considered part of head 104 and, by rule, a
player using stick 100 cannot place his/her hands on the stick in
such a way that the player's hand contacts head 104. Most players,
however, prefer to have a hand placed as close to base 110 as
allowable by rule. Using conventional stick designs, a player can
place his hands on spot 124 that is a minimum distance d1 from base
110.
[0005] Another drawback associated with conventional head 104 is
the general shape of head 104. As shown in FIG. 2, conventional
head 104 has divergent sidewalls 112 that are have an upper edge
202 and a lower edge 204 that curve to impart a concave shape to
open side 206 of head 104. FIG. 2 shows male projection 122 in
socket 118 and base 110 in phantom. Base 110 is sometimes referred
to as a ball stop. As shown in FIG. 3, a conventional straight head
300 is shown. Straight head 300 may be offset by a number of known
techniques. While these designs provide some perceived benefits
regardless of whether the design is actually offset or not, the
designs do not provide any real advantage regarding ball placement
and delivery.
[0006] Thus, it would be desirous to develop a lacrosse head that
cured these and other deficiencies of the prior art.
SUMMARY OF THE INVENTION
[0007] The present invention relates to an improved lacrosse head.
In particular, the improved lacrosse head is designed with a male
plug extending from the base. The male plug fits snuggly in a
female socket at the head end of a lacrosse shaft.
[0008] The present invention further provides an improved lacrosse
head shape. In particular, the sidewalls of the head are designed
to direct a lacrosse ball residing in the net to a predetermined
location.
[0009] The foregoing and other features, utilities and advantages
of the invention will be apparent from the following more
particular description of a preferred embodiment of the invention
as illustrated in the accompanying drawings.

DETAILED DESCRIPTION
[0018] The present invention will now be described with reference
to FIGS. 1-7. It is to be understood that the drawings are
diagrammatic and schematic representations of the presently
preferred embodiments, and are not limiting of the present
invention, nor are they drawing to scale.
[0019] The present invention relates to an improved lacrosse head
connectable to a lacrosse shaft. The connection allows placement of
a players hands close to the base of the lacrosse head. The
lacrosse head also is designed to specifically guide the lacrosse
ball to particular locations in the netting depending on the design
of the stick. For example, a forward or shooter's head may be
designed to carrier the lacrosse ball closer to the lip whereas a
defender's stick may be designed to carrier the lacrosse ball
closer to the ball stop.
[0020] Referring now to FIG. 4, a lacrosse stick 400 consistent
with an embodiment of the present invention is shown. Lacrosse
stick 400 includes a shaft 402 and a head 404. Shaft 402 has a butt
end 406 and a head end 408. Head 404 has a base 410 (or ball stop),
divergent sidewalls 412, and a lip 414 traversing divergent
sidewalls.
[0021] Extending from base 410 is a shaft junction projection 416
and a male plug 418 (which is best seen in FIG. 5). Male plug 418
has a length d3. Extending from head end 408 is a head junction
projection 420 forming a female socket 422 (which also is best seen
in FIG. 5). When connected, male plug 418 extends into female
socket 422 a length d3. However, because the head now extends
internal to the shaft (vs. external in the case of conventional
junctions), the player can place his or her hands much closer to
the base 410 than allowed with conventional designs. Male plug 418
may be solid as shown or partially hollowed out. It is believed
male plug 418 being solid provides increased strength without
compromising weight in any significant manner.
[0022] Referring now to FIG. 5 specifically, an end view of shaft
402 and head 404 is provided. Shaft 402 may have a conventional
octagonal shape 502. Shape 502 may have edges E as shown or the
edges may be rounded and/or beveled. Female socket 422 extends from
an opening 504 (defined by the shape of shaft 402) into an internal
space 506 defined by shaft walls 508. Female socket 422 optionally
may have a base 510. This shape is consistent with metallic tubular
shafts. This shape is a matter of design choice, but when using
conventional tubular metallic shafts, the shape will be somewhat
limited by technology to form the shafts. Opening 504 extends over
a majority of end 500.
[0023] Male plug 418 may have a shape generally consistent with
female socket 422. In this case, male plug 418 would have a
conventional octagonal shape 512. Male plug 418 is generally sized
to snuggly fit in opening 504. Male plug 418 may have a protrusion
514 extending about plug 418 to increase the frictional engagement.
Protrusion 514 may be molded as part of plug 418 or a washer,
rubberized component, flare, lip or the like to increase the
frictional engagement between shaft 402 and head 404.
[0024] Alternatively to a conventional metal shaft, shaft 402 may
be made of composite material, such as, a molded carbon fiber. For
more information regarding alternative shaft material, refer to
co-pending patent application serial number 10/735,596, titled
SPORTS SHAFT, filed December 12, 2003, incorporated herein by
reference. Using carbon fiber or other high density composites, it
is possible to mold provide shaft 402 with a female socket 422
having an opening 602 and extending into an internal space 604
defined by shaft walls 606 and filler 608. Filler 608 may be any
metal, plastic, or composite material, but it is believed a carbon
fiber or graphite filler would work well and be reasonably cost
effective. Socket 422 optionally has a base. Opening 602 extends
over a smaller portion of end 600. It is believed this will reduce
stress at the edges 610 of shaft 402. Male plug 418 would have a
similar shape 612 to snuggly fit in opening 602. To further
increase the strength of female socket 422, shaft walls 606 may be
lined with a strengthening material 620, such as, for example,
stainless steel, titanium, or the like.
[0025] Shape 612 could be used with a conventional metallic shaft
with an insert 614 shaped to occupy the additional volume
associated with opening 504. Insert 614 could be a number of
materials including metals, alloys, plastics, and other composites,
but it is believed graphite, carbon fiber, or the like work well as
an insert. Further, the sidewalls and plug may have bores 616 and
618 (respectively) that a securing member 622 may be inserted to
removably engage the head and shaft as is conventional in the art.
Securing member 618 may be screw, pin, bolt, or the like. Finally,
plug 418 may be lined with a strengthening material 620 similar to
the socket. As described above, the shapes of insert 614 and male
plug 418 are largely a matter of design choice.
[0026] Referring now to FIG. 7, an elevation view of a lacrosse
head 700 is shown. Lacrosse head 700 includes base 410, divergent
sidewalls 412, and lip 414 as well as male plug 418. As shown,
sidewalls 412 have an upper edge 702 and a lower edge 704. Upper
edge 704 defines an open side 706 of head 700 capable of receiving
a lacrosse ball. Lower edge 704 typically has a number of holes 708
on which a lacrosse net (not specifically shown) can be attached in
a conventional manner. Head 700 has a top half 710 towards lip 414
and a bottom half 712 towards base 410 or the ball stop.
[0027] As can been seen from the figures, Upper edge 702 can be
divided into two or more upper regions 716, 718, and 720 with one
or more transition edges 722. Bottom edge 704 can similarly be
divided into two or more bottom regions 724 and 726 with a
transition edge 728. Locating regions and transitions allows head
700 to naturally cause the lacrosse ball to reside in particular
locations in the net. For example, as shown, region 716 resides in
a first plane A, region 718 in a second plane B, and regions 720 in
a third plane C. Transition edges 722, which are shown at
approximately a 45 degree angle between the planes, connect the
regions. Transition edges 722 could be anywhere from a zero degree
to a 90 degree angle. The angle could be greater than 90 (and up
to, for example, 180 degrees) to provide a sharper edge if desired.
However, it is believed angles greater than about 110 would be
difficult to manufacture. Furthermore, while shown as at the same
angle, transition edges 722 could be at one or more angles as a
matter of design choice.
[0028] Similarly, bottom region 724 resides in a fourth plane D and
bottom 726 resides in a fifth plane E. Transition edge 728
connecting bottom region 724 and 726 can be at any angle.
Transition edge 728 is shown at a 45 degree angle.
[0029] The placement of the regions such that plane A is above
plane B is above plane C and plane D being above plane E tends to
cause the head 700 to force the lacrosse ball to the top half 710
of head 700. Reversing the orientation would tend to cause the
lacrosse ball to reside in base 410. More particularly, plane A is
below plane B is below plane C and plane D is below plane E. If it
is desired to carry the lacrosse ball about the transition between
top half 710 and bottom half 712, plane A is above plane B is below
plane C and plane D and E would be in substantially the same plane.
If there were three bottom regions, plane D is above plane E is
below plane F, for example. As one of ordinary skill in the art
would now recognize on reading the disclosure, many different
arrangements of regions could be used to cause head 700 to carry
the lacrosse ball in a desired location. Further, regions and
transition edges could be replaced by one or more curved edges to
provide the same effect.
[0030] As shown, male plug 418 has a top surface 730 defining a
surface plane S. FIG. 7 shows upper regions 716, 718, and 720
residing in planes A, B, and C above plane S. One of skill in the
art would recognize on reading the disclosure, however, that planes
A, B, and C could be above, below, or in plane with plane S as a
matter of design choice.
[0031] While the invention has been particularly shown and
described with reference to an embodiment or embodiments thereof,
it will be understood by those skilled in the art that various
other changes in the form and details may be made without departing
from the spirit and scope of the invention.
