FIELD OF THE INVENTION
This invention concerns a knitted substrate attached to the head of a lacrosse stick to form a pocket.
BACKGROUND
A lacrosse stick has a head attached to a shaft. The head has a throat local to the stick attachment, a scoop distal to the throat, and sidewalls between the throat and the scoop. The head has a pocket for holding, throwing and catching the ball. The ball is carried in the pocket local to the throat. When the ball is thrown the ball travels from the throat toward the scoop then outward away from the head. The pocket attaches to the head at the scoop, sidewalls, and throat. The pocket may be either traditional or modern mesh. The traditional pocket includes leather strings running vertically from the throat to the scoop interwoven with nylon. The use of the traditional pocket has been mostly supplanted by the use of the modern mesh pocket. The modern mesh pocket is constructed from integrally connected nylon fibers which are woven together to form diamond shaped openings in the mesh. The design of the diamond shaped openings effects the handling characteristics of the ball when carried in and thrown from the pocket. The typical modern mesh pocket comprises rows of nine to ten diamond shaped openings. Both traditional and mesh pockets have fixed connections between each diamond shaped opening that may not effectively conform to the shape of the ball when carried nor effectively guide the ball to and from the scoop when caught or thrown.
There is clearly a need for a pocket design which can retain the ball, conform to the shape of the ball and effectively guide the ball to and from the scoop when the ball is caught or thrown.

DETAILED DESCRIPTIONS
An example of a lacrosse stick 2 according to the invention is shown in FIGS. 1 and 2. The stick 2 has a substrate 4, which forms a pocket, mountable of a head 6. The head 6 and the substrate 4 support and throw a ball 7, shown in FIG. 2. The head 6 comprises a throat 8, a ball stop 12, a scoop 14, and sidewalls 16. The throat 8 is attached to a shaft 10 (a portion of which is shown in FIG. 1) which is held by the lacrosse player. The ball stop 12 is attached to the throat 8. The scoop 14 is located distal to the throat 8. The sidewalls 16 extend between the ball stop 12 and the scoop 14.
During a lacrosse game the ball is supported by the substrate 4, with the ball positioned proximate to the ball stop 12. As the ball is shot, it travels from a position local to the ball stop 12 toward the scoop 14, then past the scoop 14 and away from the head 6. When the ball is caught it travels from a position local to the scoop 14 toward the ball stop 12. The configuration of the substrate effects the handling characteristics of the ball when carried by supporting the ball, and when thrown by guiding the ball to and from the ball stop 12 to scoop 14. The various example substrate embodiments comprising a plurality of portions having different stiffness characteristics are described below.
FIGS. 3 and 4 show examples of portions of substrate 4 comprising a continuous strand of yarn 18 knit to form the substrate 4. The examples show substrate 4 formed by weft knitting with plain and purl stitches. FIG. 3 shows a portion of substrate 4 comprising the yarn 18 knit with multiple rows 20 of purl stitches 22. FIG. 4 shows a portion of substrate 4 comprising the yarn 18 knit with multiple rows 20 of plain stitches 24. Each row may also comprise combinations of plain and purl stitches.
An example substrate 4 comprising a top portion 26 and a bottom portion 28 is shown in FIG. 5. The top portion 26 is positioned proximate to the scoop 14 and the bottom portion 28 is positioned between the top portion 26 and the ball stop 12. The top and bottom portions, 26 and 28, may be knit with purl stitches 22 (see FIG. 3).
As shown in FIG. 5, the top portion 26 may include at least one shooting string 30 positioned in space relation to said scoop 14 and positioned transverse to the sidewalls 16. The shooting string 30 stiffens the top portion 26 proximate to scoop 14 preventing excessive deflection thus improving the support of the ball when thrown. FIG. 5 shows an example of substrate 4 including one shooting string 30. FIG. 6 shows an example with two shooting strings 30 positioned in the top portion 26. The two shooting strings 30 shown in FIG. 6 are in spaced apart relation to one another. The shooting string 30 may comprise a row of plain stitches 24. The row of plain stitches advantageously assists in directing the ball toward and away from the ball stop when the ball is caught or thrown. The shooting string 30 may also comprise a row of alternating plain and purl stitches. The row of alternating plain to purl stitches also advantageously assists in directing the ball toward and away from the ball stop when the ball is caught or thrown. The shooting string 30 may further comprise a fiber attached to the substrate. In this example, the fiber may be selected from a group consisting essentially of: cotton cord, nylon cord, polyester-cotton cord, cotton shoelace, nylon shoelace, polyester-cotton shoelace, hockey shoelace and combinations thereof.
FIG. 7 shows an example of substrate 32 in which the bottom portion 28 is knit with purl stitches 22 and the top portion 26 is knit with plain stitches 24.
Another example, substrate 34, comprising a top portion 26, a bottom portion 28 and a middle portion 36 is shown in FIG. 8. The middle portion 36 is positioned between the top portion 26 and the bottom portion 28. Like the top and bottom portions, 26 and 28, the middle portion 36 also includes yarn knit to form the substrate 34. In this example, the top and bottom portions, 26 and 28, of the substrate 34 may be knit with plain stitches 24. The middle portion 36 of substrate 34 may be knit with purl stitches 22.
FIG. 9 shows another embodiment, substrate 38, attached to head 2. The substrate 38 includes a first portion 40, a second portion 42 and a central portion 44. The first and second portions 40 and 42 are positioned proximate to the sidewalls 16. The central portion 44 extends from the ball stop 12 to the scoop 14 and is positioned between the first and second portions 40 and 42. The first and second portions, 40 and 42, may be knit with plain stitches 24. The central portion 44 may be knit with purl stitches 22. The substrate 38 may also include reinforcements 46 positioned in spaced apart relation to one another to advantageously direct the ball to and from the ball stop when the ball is caught or thrown. The reinforcements 46 are positioned between the first portion 40 and the central portion 44, and between the second portion 42 and the central portion 44. Each reinforcement 46 comprises a column 48 knit with plain stitches 24.
FIG. 10 shows a substrate 50 with the central portion 44, of substrate 38, including a first part 52 and a second part 54. The first part 52 extends from the ball stop 12 and the second part 54 is positioned between the first part 52 and the scoop 14. The first part 52 may be knit with purl stitches 22. The second part 54 may be knit with plain stitches 24.
The example substrates 4, 32, 34, 38, and 50 may be knit with yarn selected from a group consisting essentially of: nylon, waxed cotton, natural rope, micro-para cord and combinations thereof. Yarn from this group may be used to make the various example substrates according to the methods described below.
An example method 56 for making a substrate 4 (FIGS. 1 and 2) is shown in FIG. 11. The method 56 begins with the step 58 of casting a continuous strand of yarn onto a needle, such as a knitting needle. With the casting step 58, yarn is looped around the needle forming a first row until the desired width of the substrate 4 is reached. The number of loops of yarn along the needle is a function of a size of the needle and a circumference of the yarn. Once the casting step 58 is complete, subsequent steps continue with looping the yarn around the needle and through the previous row back and forth along the needle to complete subsequent rows. The method continues with the step 60 of knitting the yarn onto the needle to form the plurality of portions. The method further continues with the step 62 of casting the yarn off the needle, and onto the step 64 of tying off the yarn to prevent the portions from unraveling. After completion of step 66 the substrate 4 is formed and ready for the step 66 of attaching the substrate 4 to head 6 (see FIGS. 1 and 2). The substrate 4 may be attached to the head 6 by weaving nylon string through the outer periphery of the substrate and through the holes provided in the scoop 14, sides 16 and ball stop 12.
