Abstract
A lace system for a lacrosse stick that restrains thongs from sliding, maintains desired thong tension, enables convenient adjustment of thong length (in the pocket) and thong tension, provides a pocket that enhances ball control, and allows players to cut excess thong lengths to minimize their flapping around during play. The lace system includes specially shaped, sized, and positioned thong holes in the stop member of a lacrosse head, and a lace lock attached to the lacrosse stick below the thong holes. The thong holes in the stop member are not lined up in a straight line, are non-circular in shape, and are slightly smaller than the size of the thongs. The lace lock includes channeling holes and/or channels that align and compress the thongs, ridges that grip the thongs, a compression strap that locks the thongs tightly against the ridges, and a means for attaching the lace lock to the lacrosse stick.
Description




BACKGROUND




1. Field of the Invention




The present invention relates generally to lacrosse sticks, and more particularly, to a lacrosse stick having stop member thong holes and a lace lock adapted to lock thongs in place under a desired tension and in a favorable alignment, and to a method for locking the thongs in place.




2. Background of the Invention




One of the most vital components of a lacrosse stick is the lace system that forms the pocket. This pocket contributes to the overall performance of a lacrosse stick, especially with regard to ball handling. A lacrosse player relies on the feel and accuracy of the lace system for such skills as catching the ball, carrying and protecting the ball, cradling the ball, and throwing the ball. Further, a lacrosse player needs a lace system to dependably retain its characteristics during play, so that the lacrosse stick delivers superior, consistent performance even when exposed to the typical abuses of competition, such as harsh impacts, flexing, and inclement weather.





FIG. 1

illustrates a front view of a conventional molded head lacrosse stick. As shown, lacrosse stick


100


comprises a handle


102


shown in dotted lines, and a synthetic head


104


. As used herein, “stick” refers to a complete sports apparatus, of which the head and the handle are components. Head


104


comprises a generally V-shaped frame having a core area (also referred to as a throat area)


106


, sidewalls


108


and


110


, a scoop (or transverse wall)


112


joining the sidewalls at the end opposed to core area


106


, and a stop member


114


joining sidewalls


108


and


110


at the end nearest core area


106


. As shown, handle


102


fits into and through core area


106


, and abuts stop member


114


. Typically, a screw or other fastener placed through opening


107


secures handle


102


to head


104


.




For traditionally-strung pockets, four or five thongs (not shown) made of leather or synthetic material extend from upper thong holes


116


in scoop


112


to stop member thong holes


118


in stop member


114


.

FIG. 1

shows four pairs 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 eight to twelve 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 all shown generally in Tucker et al., U.S. Pat. No. 3,507,495 and Tucker et al., U.S. Pat. No. 5,566,947, which are both incorporated by reference herein in their entireties.




Traditionally strung lacrosse heads use stop member thong holes


118


arranged substantially in a straight line through stop member


114


, in generally the same horizontal plane as the bottom of head


104


. The thongs extend from upper thong holes


116


of scoop


112


, where they are typically looped and fed back through themselves, to stop member thong holes


118


in stop member


114


. Because scoop


112


and stop member thong holes


118


are in the same plane, the thongs, when taut (e.g., for a women's lacrosse stick), and the entire pocket are in one plane, remaining essentially flat. When such a pocket catches a ball and brings the ball to rest against the stop, the round shape of the ball against the flat configuration of the pocket results in minimal surface contact between the pocket and the ball. This minimal contact reduces the lacrosse head's ability to hold and protect a ball as it lies against stop member


114


. Further, the small contact area between the pocket and the ball compromises a player's accuracy during a throwing motion, when the ball travels up the pocket to the throwing strings and out of the pocket. These deficiencies in conventional lace systems noticeably detract from a player's performance and enjoyment of the game.




Although most conventional lacrosse heads align stop member thong holes in a straight line, some stop member designs feature stop member thong holes with center holes that are higher than the holes closer to the sidewalls.




In addition to the undesirable effects of conventional stop member thong hole configurations, a related problem that further frustrates player's performance is the gradual loosening of the lace system of a pocket during play. Under United States Women's Lacrosse Rules, the combined height of the lacrosse head sidewall and pocket must not exceed 2½ inches, the diameter of a regulation lacrosse ball. Because a shallower pocket makes ball control more difficult, most players attempt to keep the combined height as close to 2½ inches as possible, without exceeding the allowable height. However, because thongs are typically made of a deformable material, most often leather, the thongs and entire pocket stretch under stress from impacts with and cradling of the ball.




Aware of the desire to maximize pocket depth and the effects of stretching, lacrosse umpires routinely conduct equipment checks before and during play, on their own initiative or at the request of an opponent. According to the rules, if a pocket is found not to meet specification during play, the umpire removes the stick from the game and places it at the scorer's table for the remainder of the half. The stick, once corrected, cannot return to play until the umpire re-inspects the stick prior to the start of the second half or overtime period. For a player with a special preference for a certain lacrosse stick, this penalty can be detrimental to the player's performance. In addition, the penalty of removing sticks burdens individual players and teams with having to stock additional spare sticks. Additionally, in the event that a goal is scored with a stick subsequently determined to be illegal, that goal is nullified.




The traditional methods for complying with the pocket rules while maximizing pocket depth have been quite basic. On a typical stick, the thongs extend 10-12 inches beyond stop member


114


to enable players to pull them to adjust the pocket tension. Players fasten the thongs by threading them through stop member thong holes


118


, tying them in knots around the back of stop member


114


, and then possibly tying all of the thongs together. To keep the thongs from flapping about during play, most players tape the exposed ends of the thongs or tape the entire length of the thongs beyond the throat to the stick handle. Such jury-rigged arrangements make quick adjustment of the thongs virtually impossible. Therefore, sticks found not to meet specification cannot be readily fixed and must be removed from the game and attended to on the sidelines.




Although United States Men's Lacrosse Rules place less emphasis on a straight pocket, management of the lace system during play is still a concern. Men's rules permit a pocket depth of up to 2½ inches, below a sidewall that is up to 2 inches high. According to the traditional test, when looking horizontally at the sidewall of the men's lacrosse stick with a regulation ball inside the pocket, the sidewall must obstruct the view of at least a portion of the ball. (The total height of the sidewall and pocket must not exceed 4½ inches.) Thus, although the tension of the thongs is less critical in the men's game, players must ensure that the thongs and pockets do not sag excessively. In addition, players often desire that the excess lengths of the thongs extending from the lacrosse head stop be contained, to avoid their whipping around the head during play.




In addition to the traditional methods of tying and taping, U.S. Pat. No. 5,967,912 to Hexemer et al. is directed toward a device for locking the lacing material of a lacrosse head. This patent discloses a lace lock device that is formed integral to a lacrosse head and includes set screws, cams, and/or clamps for holding thongs in place under a desired tension. Although the clamp embodiment of the lace lock device is intended to enable a certain degree of thong adjustment while still maintaining thong tension, in actual use, the design tends to release and allow the slipping of the thongs, thereby defeating its primary purpose. The other embodiments that better secure the thongs, such as the set screws, provide considerably less adjustment capabilities. In addition to the thong tension and adjustment deficiencies, the disclosed device also cooperates with the conventional stop member thong holes that are arranged in a straight line, creating the unfavorable flat pocket. Further, the patent teaches a device that has at least one component integral to the lacrosse head, making the device incompatible with an existing lacrosse stick. Unfortunately, for the lacrosse player desiring an inexpensive retrofit, the integral design requires the costly purchase of a brand new stick.




SUMMARY OF THE INVENTION




The present invention is a lace system for a lacrosse stick that restrains thongs from sliding, maintains desired thong tension, enables convenient adjustment of thong length (in the pocket) and thong tension, provides a pocket that enhances ball control, and allows players to cut excess thong lengths to minimize their flapping around during play. According to a representative embodiment of the present invention, the lace system includes specially shaped, sized, and positioned thong holes in the stop member of a lacrosse head, and a lace lock attached to the lacrosse stick below the thong holes.




In a preferred embodiment of the present invention, the thong holes in the stop member are not lined up in a straight line, are non-circular in shape, and are slightly smaller than the thongs. For placement, the thong holes are preferably in different horizontal planes. More preferably, the thong holes toward the center of the stop member are lower than the thong holes closer to the sidewalls. (With reference to the stop member thong holes, the term “lower” as used herein means closer to the bottom of the lacrosse stick head where the pocket is situated. Likewise, “higher” means closer to the face or top of the lacrosse stick head.) Thus, in the case of a four-thong pocket, the two inner thong holes are lower than the two outer thong holes. This unique configuration gives the pocket a more rounded shape and creates a center channel running between the two outer thong holes.




Thus, instead of the flat pockets of the prior art, the present invention provides a rounded pocket that more closely conforms to the shape of the lacrosse ball, increases the surface contact between the ball and pocket, and improves the overall ball control of the stick. The center channel between the thong holes brings the ball naturally to rest in the center of the deeper pocket for easier catching. In addition, for more accurate passing and shooting, the center channel provides a controlled path through which the ball travels from the stop member toward the scoop.




The thong holes in the stop member are also preferably non-circular to properly align and orient the thongs before they enter the lace lock. The non-circular shape is preferably a rectangle, or a rounded rectangle with long horizontal sides that are flat and shorter vertical sides that are rounded. This shape resists the twisting or rotating of the thongs and keeps the wide faces of the thongs roughly at a tangent to the ball's surface and nearly parallel to the face of the lacrosse head. Alternatively, the shape of the thong holes may be an oval.




Also, preferably each thong hole is slightly smaller than the size of a cross-section of a thong so that the thong must be compressed to pass through the thong hole. In this manner, the thong hole does not allow the thong to easily slide and thereby contributes to the overall securing of the thongs.




In a preferred embodiment, the lace lock includes two sets of channeling holes that align and compress the thongs, ridges that grip the thongs, a compression strap that locks the thongs tightly against the ridges, and a means for attaching the lace lock to the lacrosse stick. The two sets of channeling holes, on the incoming and exiting sides of the lace lock, position the thongs over the ridges which are located on a curved plane to increase contact between the thongs and the ridges. Optionally, instead of the incoming set of channeling holes, the lace lock can include wedge-shaped thong channels that control the orientation of the thongs as they exit the stop member and enter the lace lock.




In a preferred embodiment of the present invention, the lace lock removably attaches to an existing lacrosse stick handle just below the stop. Therefore, although a player may not be able to retrofit an existing lacrosse stick with the stop member thong holes of the present invention, the player could attach the lace lock to an existing stick to derive the benefits of secured and easily adjustable thong tension. The means for attaching the lace lock can be any suitable fastener, e.g., a screw through the lace lock and into the handle, a hook and loop fastener attached to the sides of the lace lock and fastened around the stick handle, or an interference fit provided by matching configurations of the lace lock and handle or lacrosse head.




For the two-set channeling hole configuration, the lace lock receives the thongs from the thong holes of the stop member through its incoming channeling holes. The incoming channeling holes are adapted to keep the thongs horizontal and spaced apart from each other, so that each thong can contact the ridges evenly across its entire face. This evenly-spaced contact enables the ridges to better grip the thongs, reduce sliding of the thongs, and better maintain the desired tension of the pocket. Likewise, the exiting channeling holes are also adapted to keep the thongs horizontal and spaced apart from each other as they pass out of the lace lock.




For the wedge-shaped thong channel configuration, the lace lock includes only exiting channeling holes. In place of incoming channeling holes, the wedge-shaped thong channel is adapted to change the orientation of a thong from horizontal as it exits the thong hole to vertical as it passes through the wedge-shaped thong channel, and (working in combination with the exiting holes) back to horizontal as it exits the wedge-shaped thong channel and enters the lace lock. By changing the orientation of the thongs, the wedge-shaped thong channels further secure the thongs. The exiting channeling holes are adapted to keep the thongs spaced apart and to return the thongs to a horizontal orientation across the lace lock ridges.




With either the two-set channeling hole configuration or the wedge-shaped channel configuration, once the thongs are laced through the lace lock, a compression strap of a width substantially equal to the width of the ridged area is wrapped over the series of ridges of the lace lock and around the lacrosse stick. The ridges are preferably a textured or resilient surface that grips the thongs, e.g., sharp triangles, ridges, nubs, or spikes. The compression strap is preferably a hook and loop fastener with a fastener for looping the compression strap back over itself, drawing it tight around the stick, and joining the hooks and loops together. The compression strap forces the thongs against the ridges and locks the thongs in place. Optionally, the compression strap can be threaded through a compression plate and drawn tightly around the stick and over the ridged surface so that ridges on the compression plate line up between the ridges on the lace lock, thereby locking the thongs between the opposing ridges. In addition to securing the thongs, the compression strap can also be used to fasten the lace lock to a lacrosse stick, or alternatively, a separate hook and loop fastener could be used to fasten the lace lock to the lacrosse stick.




Together, the above components enable quick tension adjustment of the thongs, which can avoid the removal of a lacrosse stick having an illegal pocket by allowing a player to quickly shorten and tighten her pocket during a break in play if the player suspects that the pocket may have become illegal. The present invention enables a player to quickly release the compression strap, pull the thongs to the desired tension to create a legal pocket, and tighten the compression strap to keep the thongs securely locked against the ridges of the lace lock and held under the desired tension. Further, the specially sized and shaped thong holes, the wedge-shaped thong channels, and the lace lock channel holes all cooperate to further resist the movement of the thongs and to orient the thongs for optimal locking and ball roll. In addition, the specially located thong holes enhance ball control by providing a pocket that cups the ball, naturally centers the ball, and directs the ball over and out of the pocket along a straight path for more accurate throws.




In addition to quick tension adjustment, the present invention restrains the thongs from sliding loose once the desired thong tension is established between the scoop and the lace lock. And, as a further benefit, the present invention allows a player to cut the excess lengths of the thongs to prevent their flapping around during play, thereby minimizing the need for tape or other makeshift means for managing the excess thong lengths.




Accordingly, an object of the invention is to provide an apparatus that secures lacrosse head thongs and resists loosening of the thongs in the lacrosse head pocket.




Another object of the present invention is to provide an apparatus that accurately and conveniently adjusts and secures the length and tension of lacrosse head thongs.




Another object of the invention is to provide an apparatus that secures lacrosse head thongs in a position that increases the throwing accuracy of a lacrosse stick.




Another object of the present invention is to provide an apparatus that secures lacrosse head thongs on an existing lacrosse stick without requiring modification of the stick.




Another object of the present invention is to maintain thongs under a desired tension and to enable a player to manage excess thong lengths.




These and other objects and advantages of the present invention are described in greater detail in the detailed description of the invention, and the appended drawings. Additional features and advantages of the invention will be set forth in the description that follows, will be apparent from the description, or may be learned by practicing the invention.

DETAILED DESCRIPTION OF THE INVENTION




According to a representative embodiment, the present invention is a lace system for a lacrosse stick that provides quickly adjustable and positively locked pocket tension and greater ball control, using specially shaped, sized, and positioned thong holes in the stop member of a lacrosse stick, and a lace lock removably attached to the stick below the thong holes.

having incoming channeling holes

300


(shown in FIGS.


3


A and


3


B). Installed on a lacrosse stick, side


204


of lace lock


200


faces the stop member of the lacrosse stick, which has thong holes


300


.




The stop member of the lacrosse head, as shown in

FIGS. 3A and 3B

, contains thong holes


300


preferably arranged in a non-linear configuration. More preferably, thong holes


300


are located such that the inner thong holes are lower than the outer thong holes. For example, for a three-thong pocket, the single inner thong hole is at the lower position and the two outer thong holes are at the higher position. For a four-thong pocket, the two inner thong holes are preferably at the lower position. For a five-thong pocket, the single center thong hole and its two adjacent thong holes are at the lower position. Optionally, in the five-thong configuration, the center thong hole could be even lower than its adjacent thong holes.




As shown in

FIGS. 3A and 3B

, thong holes


300


are also preferably non-circular to properly align and orient the thongs before they enter the lace lock. For example, the non-circular shape could be an oval, a rectangle, or a rounded rectangle with long horizontal sides that are flat and shorter vertical sides that are rounded. Also, as shown in

FIG. 3C

, thong holes


300


preferably are slightly smaller than the size of a cross-section of a thong


302


so that thong


302


must be compressed to pass through a thong hole


300


.





FIGS. 2A-2I

illustrate from various perspectives the preferred components of lace lock


200


, including incoming channeling holes


202


, ridges


206


, and exiting channeling holes


208


. Although ridges


206


are depicted as triangular ridges, one of ordinary skill in the art would appreciate that ridges


206


could be any structure or resilient material suitable for gripping leather or synthetic thongs, such as nubs, spikes, or other textured surfaces. Preferably, incoming channeling holes


202


and exiting channeling holes


208


are adapted to keep the thongs spaced apart from each other, so that each thong evenly contacts ridges


206


. This evenly spaced contact enables the ridges to better grip the thongs, reduce sliding of the thongs, and better maintain the desired tension of the pocket.




In addition, incoming channeling holes


202


and exiting channeling holes


208


are preferably shaped to orient the thongs with the wide side of each thong facing ridges


206


, so that ridges


206


grip the larger surface areas of the thong faces. Also, preferably incoming channeling holes


202


and exiting channeling holes


208


are slightly smaller than the size of a cross-section of a thong (similar to thong hole


300


shown in

FIG. 3C

) so that the thongs must be compressed to pass through channeling holes


208


, further contributing to the locking of the thongs.




In a preferred embodiment, lace lock


200


is adapted to receive a compression strap that wraps over the area of the ridges


206


and locks the thongs in place. Preferably, the compression strap is a hook and loop fastener attached to or threaded through one or more of slots


210


and


212


, as shown most clearly in

FIGS. 2A

,


2


B,


2


C,


2


E,


2


G, and


2


I.




Lace lock


200


can be fixed to a lacrosse stick using any suitable fastening means, including only the compression strap used to lock the thongs. Preferably, however, the means for attaching lace lock


200


is a component separate from the compression strap, such as a screw driven through the lace lock and into the lacrosse stick head, the handle, or both. As another example, the means for attaching lace lock


200


could be a separate hook and loop fastener attached to one or more of slots


210


and


212


and fastened around the stick head or handle. In this manner, lace lock


200


removably attaches to an existing lacrosse stick head or handle below the stop, to enable a player to retrofit an existing lacrosse stick.




As another preferred embodiment of the present invention,

FIGS. 4A-4L

204


. As shown in

FIGS. 3A-C

, the stop member of the lacrosse head contains thong holes


300


, preferably sized, shaped, and arranged in a non-linear configuration as described above.

and channeling holes

. Although ridges


206


are depicted as triangular ridges, one of ordinary skill in the art would appreciate that ridges


206


could be any structure or resilient material suitable for gripping leather or synthetic thongs, such as nubs, spikes, or other textured surfaces. Preferably, channeling holes


208


are adapted to keep the thongs spaced apart from each other, so that each thong evenly contacts ridges


206


. This evenly spaced contact enables the ridges to better grip the thongs, reduce sliding of the thongs, and better maintain the desired tension of the pocket.




Although channeling holes


208


could be substantially circular as shown in

FIGS. 4A and 4F

, channeling holes


208


are preferably shaped to orient the thongs with their wide sides facing ridges


206


, so that ridges


206


can grip the larger surface area of the face of the thongs. For example, channeling holes


208


could be flat on the top and bottom, and round on the sides. Also, preferably channeling holes


208


are slightly smaller than the size of a cross-section of a thong (similar to thong hole


300


shown in

FIG. 3C

) so that the thongs must be compressed to pass through channeling holes


208


, further contributing to the locking of the thongs.




In a preferred embodiment, channels


402


are adapted to control the orientation of the thongs as they pass from thong holes


300


(

FIGS. 3A and 3B

) to lace lock


400


. Preferably, channels


402


are shaped, e.g., wedge-shaped, to change the orientation of the thongs from horizontal as the thongs exit thong holes


300


to vertical (90-degree rotation) as the thongs pass through channels


402


. By changing the orientation of the thongs, channels


402


further secure the thongs and prevent sliding. Once the thongs exit channels


402


, the thongs rotate 90 degrees back to horizontal and enter the interior portion of lace lock


400


. Channeling holes


208


turn the thongs the 90 degrees back to horizontal so that the thongs traverse the interior portion of lace lock


400


in a horizontal orientation better suited for contacting ridges


206


and securing the thongs.




In a preferred embodiment, lace lock


400


is adapted to receive a compression strap that wraps over the area of the ridges


206


and locks the thongs in place. Preferably, the compression strap is a hook and loop fastener attached to or threaded through one or more of slots


212


, as shown most clearly in

FIGS. 4A

,


4


B,


4


C, and


4


H.




In the preferred embodiment of the present invention, lace lock


400


removably attaches to the lacrosse stick handle using any suitable fastener, including using only the compression strap that locks the thongs against ridges


206


. Examples of other suitable fastening means are a screw driven into the stick handle (or into the head, or both the handle and head) through opening


404


as shown in

FIGS. 4A

,


4


B,


4


C, and


4


H, or a hook and loop fastener separate from the compression strap attached to or threaded through one or more of slots


212


.




In addition, lace lock


400


and the lacrosse head that receives it can be of complementary shapes or configurations such that, for example, lace lock


400


snaps into place, attaches by an interference fit, or attaches by some combination thereof

FIGS. 4I-4L

illustrate this type of interference fit.

FIG. 4L

, the shape of lace lock


410


fits in the recesses of lacrosse head


410


to provide a tight interference fit.




For both of the lace lock embodiments illustrated in

FIGS. 2A-2I

and

FIGS. 4A-4L

, the compression strap that envelops the area of the ridges


206


may further include a compression plate


500


, which is illustrated in

FIGS. 5A-5G

. Compression plate


500


includes slots


502


through which to thread the compression strap, and bearing surfaces


504


which concentrate the force of the fastened compression strap onto the thongs. The size and shape of compression plate


500


conforms generally to the size and shape of the interior portion of lace lock


200


and


400


over ridges


206


. Preferably, the shape is rectangular as viewed from a plan view (

FIG. 5C

) and is curved as viewed from a side view (

FIG. 5E

) to match the shape of a stick handle. In addition, bearing surfaces


504


and compression plate


500


are preferably made of the same hard material, e.g., ST-801 nylon by DuPont™. Alternatively, bearing surfaces


504


are made of a hard material, while compression plate


500


is preferably made of a slightly flexible material that conforms to the shape of ridges


206


and accommodates undulations typical of leather or synthetic thongs. With the compression strap thread through slots


502


and drawn tightly around the stick, compression plate


500


centers over the ridges and distributes a concentrated locking force to the thongs. Although bearing surfaces


504


are illustrated as linear structures, one of ordinary skill in the art would appreciate that other structures that provide a concentrated or point loading are equally suitable, such as pointed knobs.




The materials forming the components of the present invention preferably have durable physical properties such as toughness, impact resistance, limited flexibility, and shatterproof qualities. The preferred material is a moldable thermoplastic or thermosetting elastomer, examples of which include the nylon and urethanes well known in the art, which are typically made from reactants that are normally blended in the liquid state and cast into suitable molds to produce the lacrosse stick components. For example, lace locks


200


and


400


, and the lacrosse stick head containing thong holes


300


may be formed by injection molding of one or more synthetic polymeric materials. Preferred materials for the head and lace lock are ST-801 nylon by DuPont™ and Delron™. The lacrosse stick head could also be made of a polycarbonate such as Lexan™.




In providing secured and conveniently adjustable thong tension as well as more accurate ball control, the lace system of the present invention operates in the following manner, as illustrated in

FIGS. 6A-6G

. Although

FIGS. 6A-6G

illustrate the use of a lace lock with two sets of channeling holes, the method of operation applies equally to a lace lock with thong channels and a single set of exiting channeling holes. As shown in

FIG. 6A

, in a preferred embodiment of the present invention, a lacrosse player first removably attaches lace lock


600


to a lacrosse stick below the stop using a securing means, which in the case of

FIG. 6A

is a hook and loop fastener


602


. Optionally, the player could elect not to attach lace lock


600


to the stick at this point, and instead simply rest lace lock


600


on the stick and secure lace lock


600


to the stick later with the compression strap (which also secures the thongs). As another option, as shown in

FIG. 6B

, the player could temporarily attach lace lock


600


using an interference fit provided by matching configurations of lacrosse head


604


and lace lock


600


.




As shown in

FIG. 6C

, with lace lock


600


fastened to (or resting on) the stick, a player threads the thongs through incoming channeling holes


606


and exiting channeling holes


608


. Because of the special shape of incoming channeling holes


606


and exiting channeling holes


608


, the thongs span lace lock


600


with their wide, flat sides parallel to the face of the ridges of lace lock


600


and perpendicular to the ridges. Then, as represented by force F in

FIG. 6D

, the player pulls on the thongs to achieve the desired pocket tension and depth. (

FIG. 6D

shows only one thong for clarity.) Because the incoming channeling holes


606


, the exiting channeling holes


608


, and thong holes in the stop member of the lacrosse head are sized slightly smaller than the cross-section of a thong, the thongs are gripped to maintain a certain degree of tension.




With the thongs under the desired amount of tension, as shown in

FIG. 6E

, the player then fastens compression strap


610


around the lacrosse stick and around lace lock


600


, drawing tightly down on the thongs. Optionally, compression strap


610


could be fastened over the top of lace lock


600


only with a second strap fastened around the lacrosse stick. In either case, under this compression, the thongs lock securely against the ridges and resist sliding. In addition, having the center thongs under tension in the specially positioned thong holes in the stop member of the lacrosse head creates a center channel that improves ball control.




A lacrosse player may repeat the steps illustrated in

FIGS. 6A-6E

as many times as desired. In this manner, the present invention provides a means to quickly and conveniently adjust thong and pocket tension just before and during play, and especially after an umpire discovers an illegal pocket that must be corrected before it is returned to play. Moreover, once a player achieves the desired pocket tension, the present invention positively locks the thongs in place, prevents the thongs from sliding, and eliminates the need for constant re-tying and re-taping. The unique combination of holes and channels of the present invention also serves to lock the thongs against sliding and to orient the thongs in a configuration that maximizes ball control.





FIGS. 7A and 7B

illustrate an assembly


704


of the matching components of a lacrosse head


700


and lace lock


702


. These matching components fit integrally together to provide the locking mechanism of the present invention. As described above in reference to

FIGS. 4I-4L

, the designs of lacrosse head


700


and lace lock


702


use complementary shapes to provide an integral interference fit.




In an alternate representative embodiment of the present invention, assembly


704


of

FIG. 7A

could be a unitary structure. Thus, instead of assembling separate components, lacrosse head


700


and lace lock


702


are formed as a single piece, e.g., as a molded lacrosse head. In this way, thong holes


706


and the channels of lace lock


702


are unitary and continuous. In this embodiment, assembly


704


would provide the same structures and functions as the separate components described above (e.g., the lacrosse head and lace lock), but would do so as a unitary structure.
