1. Field of the Invention
The present invention relates generally to lacrosse sticks, and more particularly, to a lacrosse stick head having a wide catching area and channeled thongs.
2. Background of the Invention
In 1970, the introduction of double-wall, synthetic lacrosse heads revolutionized the game of lacrosse. In comparison to the traditional wooden single-wall heads, the synthetic heads imparted a balance, lightness, maneuverability, and flexibility never-before experienced by lacrosse players. These performance advantages greatly enhanced players' skills such as throwing, catching, cradling, and scooping, and brought the sport of lacrosse to new levels of speed and excitement.
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 scoop 112 to lower thong holes 118 in stop member 114. In some designs, such as the design shown in
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 hole 124 and a string laced through string hole 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.
In addition to traditionally strung heads, some heads use mesh pockets or a combination of traditional and mesh stringing. In any case, the mesh or stringing is conventionally attached to the head through holes in the scoop, sidewalls, and stop members, or by tabs attached to the scoop, sidewalls, and stop members. These tabs can have openings through which mesh or stringing is threaded, or can be shaped (e.g., like a hook) to retain loops of the mesh or stringing.
As used herein, thread holes or thread openings refer to the openings that receive the various forms of pocket stringing, such as the holes in the scoop, sidewalls, and stop members, or the openings in tabs attached to the scoop, sidewalls, and stop members. The term “openings” should be construed broadly so as to encompass any hole or structure that retains the pocket stringing, including structures such as hooks. Also, as used herein, a pocket thread refers to any member, such as a thong, string, or mesh, that forms the pocket and/or attaches the pocket to the lacrosse head.
The traditional shape of a lacrosse head is commonly referred to as generally V-shaped. In other words, looking at the face of a lacrosse head, the width between the sidewalls increases as the sidewalls extend from the ball stop to the scoop, with the widest point being in the area of the transition between the sidewalls and the scoop. Typically, rules applicable to competitive lacrosse dictate the minimum width a lacrosse head must possess (e.g., 6½ inches). According to conventional thinking, providing the greatest width near the scoop enables a player to more easily scoop ground balls and catch thrown balls, and direct the balls down into the pocket of the lacrosse head.
With respect to scooping ground balls, improvements in the ball retention characteristics of lacrosse heads have changed the modem game of lacrosse such that it is now more difficult to check balls loose and create ground ball opportunities. Simply put, there are less ground balls in the modem game of lacrosse than were typical in years past. Consequently, the modem game emphasizes precise passing and catching over the scooping of ground balls.
In addition, with respect to catching thrown balls, it is now recognized that most players catch a ball in the center section of a lacrosse head, and not within the widest portion of the head near the scoop. Thus, players are more apt to miss a ball as it bounces off the closely positioned sidewalls in the center area of the head.
U.S. Pat. No. 5,685,791 to Feeney discloses a lacrosse head having a shape somewhat contrary to this conventional thinking. Feeney discloses a composite lacrosse head in a generally circular, or closed loop, configuration. Viewed from the front face, the central section of the Feeney head is of the greatest width. Starting from the ball stop, the sidewalls of the head immediately diverge away from each other in slightly convex lines to the point at which the central section reaches its greatest width. From that point to the scoop, the sidewalls converge toward each other in concave lines.
As used herein, the terms concave and convex are discussed relative to the interior area defined by the ball stop, sidewalls, and scoop of a lacrosse head. In other words, looking at the front face of a lacrosse head, a convex sidewall bends toward the interior of the lacrosse head, while a concave sidewall bends away from the interior of the lacrosse head. The bending of a sidewall can be judged, for example, relative to a point drawn roughly in the center of the interior area of the lacrosse head.
Although the lacrosse head of Feeney may provide a larger catching area in the center area of the head, this increased area raises additional drawbacks. For example, the increased area enables a ball to rattle more within the head, making the control and retention of the ball difficult. In addition, the ordinary interwoven string pocket shown and described in Feeney compounds the difficulties in avoiding this ball rattle. In addition, because the sidewalls of Feeney diverge immediately starting from the ball stop, a ball can easily rattle and exit the head at locations very close to the ball stop.
Thus, in view of the drawbacks of conventionally shaped heads, there remains a need for a lacrosse head that provides a wide catching area, yet maximizes ball retention and control.
The present invention provides a lacrosse head that, in addition to providing a wide catching area, provides important aspects of ball retention and control.
An embodiment of the present invention provides an exemplary lacrosse head that includes a stop member, a left sidewall connected to the stop member, a right sidewall connected to the stop member, and a scoop connecting the left sidewall to the right sidewall opposite the stop member. The scoop is disposed about 25.5 cm from the stop member. The widest point of the lacrosse head is in a catching section disposed from about 6 cm to about 17 cm from the stop member. The left sidewall is convex at a portion of the left sidewall between the widest point and the scoop. The right sidewall is convex at a portion of the right sidewall between the widest point and the scoop. The convex sidewalls between the widest point and the scoop provide a narrower, funneled pocket through which a ball exits the head, thereby providing improved ball control and more accurate passing.
In a further aspect of the present invention, the width of the scoop is in a range from about 5 cm to about 15 cm measured perpendicularly to the shaft axis between the left sidewall and the right sidewall. This narrow width contrasts sharply with the wide scoops of traditional heads and with the widest point of the catching section. The narrow scoop funnels a ball out of the pocket during throwing to increase the accuracy of passes and to counteract any reduction in ball control that the wide catching area may cause.
In a further aspect of the present invention, the sidewalls rise from the plane of the scoop and include thong holes. In one embodiment, the scoop defines two inside thong holes, the left sidewall defines a left outside thong hole, and the right sidewall defines a right outside thong hole. This placement of the thong holes in conjunction with the rising sidewalls provides channeled thongs that help guide the ball in a straight line out of the pocket, and counteract any reduction in ball control that the wide catching area may cause.
In a further aspect of the present invention, the sidewalls are parallel to each other in the section of the lacrosse head between the stop member and the catching section. This parallel configuration further helps ball control and retention. In a further aspect of the present invention, the width of the scoop is less than the distance between the parallel sidewalls.
As discussed herein, measurements of the distance between sidewalls are taken from roughly the inside of the sidewalls, i.e., measuring the clear opening between the sidewalls. For example, such a measurement could be taken from the inside top rim of one sidewall to the inside top rim of the other sidewall. The measurements of the distance between sidewalls are also taken roughly perpendicularly to the shaft axis.
As shown by the dotted lines 298 and 299 in
In a particular implementation of this embodiment of the present invention, the distance 226 from the middle of ball stop 214 to the end of scoop 212 is approximately 25.5 cm. The distance 228 from the middle of ball stop 214 to the line 299 between rearward section 220 and catching section 222 is approximately 6 cm. The distance 230 from the middle of ball stop 214 to the line 298 between catching section 222 and forward section 224 is approximately 17 cm.
As one of ordinary skill in the art would appreciate, the dimensions of rearward section 220, catching section 222, and forward section 224 could vary as desired for a particular application, such as for a men's or women's lacrosse stick head, for junior lacrosse stick heads, for offensive or defensive lacrosse stick heads, or for recreational or trick lacrosse stick heads. In general, for men's or women's competitive lacrosse stick heads, the distance 226 could range from about 25 cm to about 31 cm, the distance 230 could range from about 16 cm to about 23 cm, and the distance 228 could range from about 3 cm to about 7 cm.
As shown in
An important aspect of the present invention is the manner by which sidewalls 208 and 210 transition between ball stop 214, the widest point 232 of catching section 222, and scoop 212. Preferably, within rearward section 220, sidewalls 208 and 210 remain substantially parallel. From line 299 (between rearward section 220 and catching section 222) to near the widest point 232 of catching section 222, sidewalls 208 and 210 preferably diverge (i.e., the distance between them increases) along convex lines. From near the widest point 232 of catching section 222 to near scoop 212, sidewalls 208 and 210 preferably converge along convex lines. The net result of this sidewall configuration is that lacrosse head 200 is pinched above and below the widest point 232 of catching section 222.
With continuing reference to
A further aspect of the present invention provides a dramatic convex transition of sidewalls 208 and 210 between near the widest point 232 of catching section 222 and the line 299 between catching section 222 and rearward section 220. This significant decrease in width between sidewalls 208 and 210 creates a markedly pinched configuration and quickly brings sidewalls 208 and 210 to the minimal distance apart that is held in rearward section 220, where sidewalls 208 and 210 are substantially parallel.
In one exemplary head, referring to
In a further embodiment of the present invention,
As shown in
In one implementation, at the line 499 between rearward section 420 and catching section 422, the distance between sidewalls 408 and 410 is about 7 cm and line 499 is a distance 428 of about 7 cm from ball stop 414. The widest point 402 of catching section 422 is about 16.5 cm and is located at a distance 434 of about 15 cm from ball stop 414. At the line 498, which is located at a distance 430 of about 17 cm from ball stop 414, the distance between sidewalls 408 and 410 is about 14 cm. The distance 426 from ball stop 414 to the end of scoop 412 is approximately 25.5 cm. Finally, the width 404 of scoop 412 is about 8 cm.
As represented by the dotted lines 413 in
As used herein to describe the higher and lower relative positions of the scoop, the sidewalls, and thongs attached to the scoop and sidewalls, a plane is parallel to the face of a lacrosse head, which is defined generally by the top edges of the stop member and sidewalls. One plane, for example, is defined by the shaft axis and a line that is drawn perpendicularly to the shaft axis and intersects equivalent points of the sidewalls (i.e., the line intersects a point on the first sidewall and a point on the second sidewall that are both a substantially equal distance below the top edge of their respective sidewalls).
Referring to
Overall, embodiments of the present invention provide many benefits over conventional lacrosse heads. Placing the widest point of the head in the catching section, and not in the forward section, makes it easier for players to catch lacrosse balls. Narrowing the scoop and changing the plane of the sidewalls with respect to the scoop guides the ball so that the ball leaves the pocket in a more funneled manner, thereby improving playability. Further, the reshaped and resized scoop, along with the novel placement of thong holes on the sidewalls, places the thongs, or leathers, in different planes than do conventional heads. The two outside thongs that are disposed on the sidewalls are raised relative to the two inside leathers, which creates a channel effect. Thus, although during a throw the ball has more space in which to rattle in the catching section where the head is wider, the channel prevents this rattling and controls the exiting of the ball. As a result, a lacrosse head of the present invention provides a wider catching area where the ball is intended to be caught, but overcomes the potentially negative consequence of ball rattle via the stringing channel.
The wider catching section provides other benefits as well. For example, the wider area of the catching section allows the stringing to sag more in the pocket across this wider area during cradling, in comparison to conventional heads. This sagging effect increases the centrifugal force while the ball is being cradled, which stabilizes the ball in the pocket. During the throwing motion, however, less centrifugal force is exerted on the pocket, which lessens sag, thereby maintaining the accuracy of the throw.
The wider catching section and narrower forward section also provide a more favorable center of gravity in comparison to conventional lacrosse heads. The wider catching section shifts more weight of the head toward the player's hand positioned just below the throat of the head. This shift in weight places the center of the gravity of the head closer to the player's hand, giving the player a better feel for the position of the head and providing a greater sense of control. In addition, shifting mass from the forward section to the catching section decreases the radius from center of gravity to the axis of rotation, thereby decreasing the torque on the head and increasing the player's control and feel of the ball in the pocket.
As another benefit, the present invention pinches the scoop area creating a narrow channel for throwing accuracy. Repeatedly, the ball is released from the center most point on the stick as opposed to a conventional head where there is limited control over the angle the ball is released off the wide scoop. The track that is formed by the forward pinched characteristic of the head of the present invention forces the ball to be released from the center of the scoop, which is the highest point on the head.
In addition, the invention allows for a greater moment of inertia. The moment of inertia is the sum of all the masses multiplied by the radius squared. When the mass (i.e., the ball) is concentrated farther away from the axis of rotation or higher on the head, the moment of inertia will be greater, thus giving strength to the shot. The greater the moment of inertia, the more difficult it is for an external force to change the position of the head, therefore, providing accuracy to a throw or shot from the head.
According to an aspect of the present invention, a lacrosse head having a wide catching section, such as head 200 shown in
