Description
[0001] This is a continuation of U.S. patent application Ser. No.
11/073,750, filed Mar. 8, 2005, which is herein incorporated by
reference in its entirety.
BACKGROUND
[0002] 1. Field of the Invention
[0003] The present invention relates generally to lacrosse sticks,
and more particularly, to a lacrosse stick having a downwardly
canted handle and an upwardly canted head.
[0004] 2. Background of the Invention
[0005] FIG. 1 illustrates a conventional lacrosse stick 100 having
a handle 102 shown in dotted lines and a double-wall synthetic head
104. Head 104 comprises a throat portion 105 and a frame portion
109. Frame portion 109, which is generally V-shaped in this
example, comprises a stop member 114, sidewalls 108 and 110 joining
stop member 114, and a transverse wall (or "scoop") 112 joining the
sidewalls at their ends opposite stop member 114. As shown, handle
102 connects to throat portion 105 and abuts stop member 114. A
screw or other fastener placed through opening 107 secures handle
102 to head 104.
[0006] For traditionally-strung pockets (which have thongs and
string instead of mesh), thongs (not shown) made of leather or
synthetic material extend from upper thong holes 116 in transverse
wall 112 to lower thong holes 118 in stop member 114. In some
designs, such as the design shown in FIG. 1, upper thong holes 116
are located on tabs 117 of the scoop 112. On other designs, upper
thong holes 116 are located directly on the scoop 112. FIG. 1 shows
four pairs (116, 118) of thong holes that accept four thongs. To
complete the pocket web, the thongs have nylon strings threaded
around the thongs and string laced through string holes 120 in
sidewalls 108 and 110, forming any number of diamonds
(crosslacing). Finally, one or more throwing or shooting strings
extend transversely between the upper portions of sidewalls 108 and
110, attaching to throwing string holes 124 and a string laced
through string holes 122. The typical features of a lacrosse stick
are shown generally in Tucker et al., U.S. Pat. No. 3,507,495,
Crawford et al., U.S. Pat. No. 4,034,984, and Tucker et al., U.S.
Pat. No. 5,566,947, which are all incorporated by reference
herein.
[0007] As shown in FIG. 1, the traditional means for affixing head
104 to handle or shaft 102 involves sliding shaft 102 into throat
portion 105 of head 104 and securing head 104 to shaft 102 with a
screw or similar fastener placed in opening 107. In this
configuration, the axis of handle 102 and the axis of throat
portion 105 are coincidental. In FIG. 1, throat portion 105
provides a female connection (e.g., a socket) that receives shaft
102. Alternatively, in addition to or in place of the female
connection, throat portion 105 can provide a male plug that fits
within the bore of shaft 102, as is disclosed, for example, in U.S.
patent application Ser. No. 10/630,856, filed Jul. 31, 2003, which
is herein incorporated by reference in its entirety.
[0008] When double-wall synthetic lacrosse heads were first
introduced, the early designs featured straight handles and
straight heads, when viewed from a side elevation facing a sidewall
of the head. In other words, the lacrosse head remained largely in
line with the axis of the handle. Since those early designs,
however, the trend has been to lower the lacrosse head below the
handle axis. Lowering the head can enable better ball control and
provide a player with an indication of the orientation of the
lacrosse head, which results from the uneven weight distribution
relative to the handle axis in directions radial to the handle
axis.
[0009] Despite these advantages, the lacrosse sticks having lowered
heads can also introduce undesirable ball handling characteristics
because the ball is positioned a greater distance below the shaft
axis and must travel a greater distance to release from the head.
Traditionally, designers have lowered heads either by reshaping the
handle or by lowering the sidewalls adjacent to the throat portion.
In either case, the reconfiguration positions the ball a greater
distance from the shaft axis. Compounding this problem, the
reconfiguration can cause the ball to come to rest in a rear head
position (i.e., more toward the stop member). This rear head
position, combined with the greater travel, can create difficulties
in releasing the ball from the head, and can therefore hinder a
player's ability to execute quick and accurate shots and
passing.
SUMMARY OF THE INVENTION
[0010] An embodiment of the present invention provides a lacrosse
stick having a downwardly canted handle and an upwardly canted
head. As used herein, downwardly and upwardly refer to vertical
directions when viewed from a side elevation of a lacrosse stick
facing a sidewall of the lacrosse head. FIG. 2A illustrates this
view. As also used herein, canted refers to the quality of
departing from a straight line, such as departing from a horizontal
line drawn in FIG. 2A (e.g., line 210). In the context of the
present invention, a canted handle has a portion that departs from
the axis of another portion when viewed from a side elevation.
Likewise, a canted head has a portion that departs from the axis of
another portion when viewed from a side elevation.
[0011] In an embodiment of the present invention, the handle can
comprise a main portion and a dowel portion. The main portion can
have a main portion axis and the dowel portion can have a dowel
portion axis. The dowel portion axis can be disposed downwardly at
a first angle to the main portion axis. The head can comprise a
throat portion and a frame portion. The frame portion can be
upwardly canted with respect to the throat portion, when viewed
from a side elevation.

DETAILED DESCRIPTION OF THE INVENTION
[0022] FIG. 2A illustrates a lacrosse stick 200 according to an
embodiment of the present invention. As shown, lacrosse stick 200
includes a handle 202 and a head 204. Handle 202 includes a main
portion 206 and a dowel portion 208. Handle 202 is downwardly
canted in that dowel portion 208 departs from the axis 210 of main
portion 206 in a downward direction below the main portion axis 210
when viewed from a side elevation as shown in FIG. 2A. In this
manner, the main portion axis 210 and the axis 212 of dowel portion
208 are at an angle 214 to each other. This angle 214 is measured
counterclockwise from main portion axis 210 to dowel portion axis
212 as shown in FIG. 2A. Angle 214 can range from greater than 0
degrees to about 90 degrees, but is, in one implementation, within
a range of approximately 3 degrees to approximately 25 degrees.
Main portion 206 can be longer than dowel portion 208, and can
provide the principal structure by which a player holds lacrosse
stick 200.
[0023] Head 204 includes a throat portion 220 and a frame portion
222. Throat portion 220 receives dowel portion 208 of handle 202.
In this example, throat portion 220 provides a collar inside of
which dowel portion 208 is disposed and a male plug (not shown)
that is disposed within dowel portion 208. The axis of throat
portion 220 can be coaxial with the dowel portion axis 212.
[0024] As shown in FIG. 2A, head 204 is upwardly canted in that
frame portion 222 departs from throat portion 220 in an upward
direction. In one aspect of the invention, frame portion 222 is
upwardly canted with respect to the throat portion 220 at a point
roughly between the frame portion 222 and the throat portion 220.
For example, this point could correspond to the uppermost edge of
head 204 directly above the end of the dowel portion 208 opposite
main portion 206.
[0025] In another aspect of the invention, frame portion 222 is
upwardly canted with respect to the throat portion 220 at a point
roughly corresponding to the uppermost edge of head 204 directly
above the stop member of head 204. At this location above the stop
member, the sidewalls could cant upward relative to the stop
member.
[0026] In another aspect of the invention, the upward canting
between frame portion 222 and throat portion 220 occurs at a
location more forward (i.e., toward the scoop) in the head 204.
FIG. 2A illustrates this aspect, with a gradual canting occurring
at approximately the area of point 227.
[0027] In another aspect of the invention, head 204 is upwardly
canted in that the axis 224 of frame portion 222 departs from the
axis 212 of throat portion 220 in an upward direction when viewed
from a side elevation as shown in FIG. 2A. In this manner, the
frame portion axis 224 and the throat portion axis 212 are at an
angle 216 to each other. This angle 216 is measured
counterclockwise from frame portion axis 224 to throat portion axis
212 as shown in FIG. 2A. Angle 216 can range from greater than 0
degrees to about 90 degrees, but is, in one implementation, within
a range of approximately 3 degrees to approximately 25 degrees.
[0028] According to this aspect of the invention, the frame portion
axis 224 can be defined as a line starting from the midpoint of the
end of the dowel portion of the shaft and extending roughly
parallel to the upper and lower edges of the sidewalls, at a region
of the sidewalls at which the upper and lower edges of the
sidewalls are roughly parallel (e.g., in area 225). In the
configuration of FIG. 2A, in extending roughly parallel to the
sidewall edges, axis 224 extends roughly parallel to the main
portion axis 210. In alternative configurations, however, the
sidewall edges and the frame portion axis 224 may not be roughly
parallel to the main portion axis 210 and could, for example, rise
in a direction from the throat portion 220 to the scoop of the head
204.
[0029] Alternatively, the frame portion axis 224 can be defined as
a line drawn from the midpoint of the end of the dowel portion to
the uppermost edge of the scoop. In the configuration of FIG. 2A,
under this definition, the frame portion axis 224 is roughly
parallel to the main portion axis 210. In alternative
configurations, however, a frame portion axis 224 under this
definition may not be roughly parallel to the main portion axis 201
and could, for example, rise in a direction from the throat portion
220 to the scoop of the head 204.
[0030] To better illustrate the canting of the frame portion 222
with respect to the throat portion 220 in head 204, FIG. 3
illustrates an exemplary upwardly canted head 304 that is similar
to head 204 of FIG. 2A and is attached to a straight handle 300. As
the straight handle 300 highlights, the frame portion 322 of head
304 rises from the throat portion axis 312, which in this case is
coincidental with the axis 302 of straight handle 300. This view
shows that the frame portion 322 is at an angle to the throat
portion 320.
[0031] Referring again to FIG. 2A, the angle by which frame portion
axis 224 is canted from the throat portion axis 212 determines the
placement and alignment of the frame portion 222 with respect to
the main portion 206 of the handle 202. In the example of FIG. 2A,
because the main portion axis 210 is roughly parallel to the frame
portion axis 224, the angle 214 by which the handle is downwardly
canted is approximately equal to the angle 216 by which the head is
upwardly canted. In other words, angles 214 and 216 are
corresponding angles. Although shown as roughly parallel in FIG.
2A, the frame portion axis 224 and the main portion axis 210 do not
have to be roughly parallel, in which case angles 214 and 216 would
not be equal.
[0032] In one embodiment of the present invention, the angle 216
cants the frame portion 222 sufficiently upward such that the upper
edges of the sidewalls of the head 204 are at or above the main
portion axis 210, as that axis is extended through the head 204 as
shown in FIG. 2A. At the same time, the scoop of lacrosse head 204
can be disposed below main portion axis 210, as is shown in FIG.
2A. In addition, the upper edge of the sidewalls of head 204, when
viewed from a side elevation, can be substantially parallel to the
main portion axis 210 along a portion of the sidewalls. In FIG. 2A,
the upper edges of the sidewalls are roughly parallel to main
portion axis 210 along a length 225 of the sidewalls between the
scoop and the throat portion. In this same area 225, the upper and
lower edges of the sidewalls are roughly parallel.
[0033] As shown in FIG. 2B, in another embodiment of the present
invention, the angle 216 cants the frame portion 222 sufficiently
upward such that no portion of head 204 extends below a line 230
drawn parallel to a line 226 corresponding to the upper face of
handle 202 at a certain distance 228 between lines 226 and 230.
Commonly accepted rules of lacrosse dictate this distance 228. For
example, the men's lacrosse rules promulgated by the National
Collegiate Athletic Association (NCAA) currently set this distance
228 at about 2.75 inches.
[0034] By using a downwardly canted handle in conjunction with an
upwardly canted head, the head can be offset closer to the limits
of distance 228 (i.e., line 230) than has previously been possible.
Indeed, if an ordinary straight head or offset head were attached
to a canted handle of the present invention, the head would be
disposed downward and well outside the distance 228. FIG. 4
demonstrates this point, showing a straight head 400 mounted on the
exemplary canted handle 202 of FIG. 2A, with the head 400 disposed
outside distance 228. In the present invention, however, the
combination of the downwardly canted handle and the upwardly canted
head enables not only the lowering of the head (e.g., the sidewalls
of head 204 are below the line 226), but also the proper location
and alignment of the lower portions of the sidewalls so that the
head remains within the distance 228. In essence, the downward cant
of the handle lowers the upper edges of the head and the upward
cant of the head keeps the lower portions of the head (e.g., lower
edge of sidewalls) within distance 228.
[0035] In downwardly canting the handle and upwardly canting the
head, one of ordinary skill in the art would appreciate the
interplay between the chosen angles 214 and 216, and the effects
that certain dimensions may have on achieving a maximum lowering of
the head that still complies with the applicable rules. For
example, the length of the throat portion 220 of head 204 and the
dowel portion 208 of handle 202, along with angles 214 and 216, can
affect the positioning of head 204.
[0036] In one implementation that complies with the NCAA 2.75 inch
rule, dowel portion 208 is approximately 2 inches, angles 214 and
216 are approximately 10 degrees, the maximum height of the throat
and sidewalls is about 2 inches, and the length of head 204 is
about 11 inches including throat portion 220 and frame portion 222.
In other implementations, angle 214 is within a range of
approximately 3 degrees to approximately 25 degrees and the length
of the dowel portion 208 is within a range of approximately 1 to
approximately 5 inches. With a longer dowel portion 208, the angle
214 could be smaller. For example, if the dowel portion 208 and
main portion 206 are roughly equal in length (e.g., the cant is at
the center of the handle), then angle 214 is slight. Varying these
angles and lengths could provide lacrosse sticks with different
feel and performance characteristics, as desired.
[0037] In addition, although FIG. 2A illustrates a handle 202 and
head 204 in which a first portion departs linearly from the axis of
a second portion (e.g., dowel portion axis 212 departs linearly
from main portion axis 210), one of ordinary skill in the art would
appreciate that the first portion could depart from the second
portion along a curve. For example, instead of having linear
portions 208 and 206 abutted to each other as is shown in FIG. 2A,
handle 202 could have a curved transition in between the linear
portions 208 and 206 that transitions main portion axis 210 into
dowel portion axis 212. Likewise, head 204 could include a curved
portion that transitions throat portion axis 212 into frame portion
axis 224.
[0038] In an embodiment of the present invention, in which the
angles 214 and 216 are approximately 90 degrees, the dowel portion
axis 212 and the throat portion axis 212 are essentially vertical
in FIG. 2A. In this configuration, dowel portion 208 could be
disposed, for example, in a hole defined by throat portion 220,
with the axis 240 of the hole roughly parallel to the y-axis shown
in FIG. 2A. FIG. 2C illustrates this embodiment of the present
invention. As another example, dowel portion 208 could be connected
to a male plug protruding from throat portion 220, with the axis of
the male plug roughly parallel to the y-axis shown in FIG. 2A, and
with the male plug disposed in the bore of dowel portion 208. As
another example, throat portion 220 could define both a gap and a
male plug that connect to the dowel portion 208 as shown in FIG.
2A, with the axes of the gap and the male plug roughly parallel to
the y-axis shown in FIG. 2A, and with the wall of the dowel portion
208 disposed in the gap and the male plug disposed in the bore of
the dowel portion 208.
[0039] The downwardly canted handle and upwardly canted head of the
present invention lower the center of mass of the head in the
y-direction (see FIG. 2A) to provide a lowered head feel for
orientation. At the same time, the gradual lowering of the head
provided through the cants in the handle and head place a ball in
the pocket further forward in the head when shooting and passing.
Moreover, as described above in reference to line 230 of FIG. 2B,
the canted handle and head enable the head to be precisely lowered
and oriented up to the maximum distance allowable under commonly
accepted rules of lacrosse (e.g., about 2.75 inches).
[0040] The lowered center of mass and the forward placement of the
ball provide a better-playing lacrosse stick. By gradually canting
the handle, the head throat portion, and the head frame portion
towards the cradling, throwing, and receiving part of the net, the
shooting and passing capabilities of the stick improve because the
ball naturally comes to rest more forward in the head in comparison
to conventional canted or offset heads. This gradual cant through
the handle and head is preferable to a more severe offset of the
sidewalls, which can impede passing and shooting. In this manner,
the downwardly canted handle and upwardly canted head of the
present invention can lower the head over a longer distance with a
more gradual slope from the main portion axis 210 of the handle
202.
[0041] Tests have been conducted to compare the y-direction center
of mass of conventional lacrosse sticks to an exemplary stick
according to the present invention. In these tests, the plane of
the handle and the plane of the bottom edge of the sidewalls were
kept the same in all of the sticks. The center of mass of each
stick was determined with the shaft parallel to the x-axis. Three
types of conventional lacrosse sticks were tested: (1) a
conventional straight sidewall and straight handle stick (e.g., STX
Excalibur.TM.); (2) a conventional lowered head stick using an
abrupt offset sidewall head and straight handle (e.g., Brine
Edge.TM.); and (3) a conventional lowered head stick using a canted
offset head and a straight handle (e.g., STX Proton +.TM.). These
tests showed that a stick having a canted handle and head of the
present invention had a y-direction center of mass lower than the
conventional straight sidewall and straight handle stick, and
roughly equal to the y-direction centers of mass of the abrupt
offset sidewall head and the canted offset head.
[0042] Assuming all other lacrosse head variables to be equal
(e.g., pocket depth and sidewall openings), the center of mass in
the y-direction can dictate the extent to which a player feels the
ball in the head and how readily the ball releases from the head
when passed or shot. With a straight sidewall head and handle, a
player can experience very little feel for the ball in the head, as
the center of mass in the y-direction is located toward the upper
rails of the sidewall and is more in the same plane as the player's
hands when gripping a handle. In this configuration, however, the
ball can release very quickly out of the straight head and handle
stick due to the shorter distance the ball must travel and the
mid-head position that the ball assumes.
[0043] In the present invention, a player experiences more feel for
the ball in comparison to a straight head and handle stick because
the center of mass in the y-direction for the present invention is
located more toward the bottom rail. At the same time, the present
invention enables a forward ball position, in which the ball rests
closer to the scoop. This forward ball position improves feel for
the ball and release of the ball from the pocket. Such
characteristics provide a lacrosse stick with superior ball
handling and throwing capabilities.
[0044] FIGS. 5-8 illustrate an exemplary lacrosse head 500
according to an embodiment of the present invention. In this
example, the lacrosse head 500 has a 10 degree cant (corresponding
to angle 216 of FIG. 2A) and is adapted to connect to a handle (not
shown) having a 2 inch dowel portion (corresponding to dowel
portion 208 of FIG. 2A). The lacrosse head 500 also includes a male
plug 502 adapted to be disposed within a handle.
[0045] Although some of the figures illustrate embodiments of the
present invention having roughly octagonal-shaped handles, it
should be understood that a lacrosse stick according to the present
invention could be adapted to fit any variety of shaft shapes, such
as teardrop, asymmetrical, and oval. Indeed, the lacrosse stick of
the present invention could be adapted to accommodate a cylindrical
shaft or a shaft having any number of sides.
[0046] Examples of suitable materials for a lacrosse head according
to the present invention include nylon, composite materials,
elastomers, metal, urethane, polycarbonate, polyethylene,
polypropylene, polyketone, polybutylene terephalate, acetals (e.g.,
Delrin.TM. by DuPont), acrylonitrile-butadiene-styrene (ABS),
acrylic, acrylic-styrene-acrylonitrile (ASA), alcryn (partially
crosslinked halogenated polyolefin alloy),
styrene-butadiene-styrene, styrene-ethylene-butylene styrene,
thermoplastic olefinic (TPO), thermoplastic vulcanizate (TPV),
ethylene-propylene rubber (EPDM), and polyvinyl chloride (PVC).
[0047] Examples of suitable materials for a handle according to the
present invention include wood, metal (e.g., aluminum, titanium,
scandium, CU31, C405, and CS55), plastic, and composites. Methods
for manufacturing the handle can include welding the dowel portion
to the main portion, hot or cold forming a bend or curve into the
handle, molding material to form the handle, sintering particles to
form the handle, extruding the handle with a bend or curve, and
laying up composite materials in the desired shape.
[0048] In one implementation of the present invention, a handle is
formed by rotary-draw cold bending, in which material (e.g., tube)
is drawn around a rotating bend form without heating. The forward
tangent of the material is clamped to the bend die and is drawn
around the die as it rotates, while the back tangent is held in
place against the rotating bend die by a pressure die. Thus, the
point of contact between the rotating bend die and the pressure die
is the line of tangency. What distinguishes rotary-draw bending
from other methods is that this line of tangency is fixed in space.
Therefore, mandrel and wiper tooling can be fixtured at the point
of bend to fully control the flow of material. This control helps
to produce tube bends of superior quality.
[0049] In another implementation of the present invention, a handle
is formed by press bending, sometimes referred to as vertical
bending. Press bending is distinguished from rotary-draw bending by
the fact that when the ram die (analogous to the bend die in
rotary-draw bending) pushes the tube through a pair of wing dies
(analogous to the pressure die in rotary-draw bending), two lines
of tangency form following the points of contact between the
circumference of the ram die and each face of the two wing
dies.
[0050] In another implementation of the present invention, a handle
is formed by hydroforming. Hydroforming uses fluid pressure in
place of a punch in a conventional tool set to form the part into
the desired shape of the die. This technique is very useful for
producing whole components that would otherwise be made from
multiple stampings joined together.
[0051] In another implementation of the present invention, a handle
is formed by hot bending or hot forming. In this method of bending,
the ductility of the tubing material is increased by heating it
either before placement on the machine or in-process. Usually,
in-process heating of the material is done indirectly, e.g., with
heating elements fixtured in the tools so that the material is
heated by conduction through the tools.
[0052] Although embodiments of the present invention describe
exemplary lacrosse sticks having handles attached to heads by
female and/or male mechanical connections and with screws or other
fasteners, one of ordinary skill in the art would appreciate that
the present invention is equally applicable to unitary lacrosse
sticks. For example, the entire handle and head could be formed as
one piece, from laid-up composite materials, similar to methods by
which some tennis racquets are manufactured. For this reason, the
present invention should not be limited to lacrosse sticks
assembled from separate components.
[0053] The foregoing disclosure of the preferred embodiments of the
present invention has been presented for purposes of illustration
and description. It is not intended to be exhaustive or to limit
the invention to the precise forms disclosed. Many variations and
modifications of the embodiments described herein will be apparent
to one of ordinary skill in the art in light of the above
disclosure. The scope of the invention is to be defined only by the
claims, and by their equivalents.
