Abstract

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. Related methods of manufacturing also are provided.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A lacrosse pocket comprising:
a pocket longitudinal axis;
an upper pocket portion adapted to connect to a lacrosse head scoop;
a lower pocket portion adapted to connect to a lacrosse head base;
a middle pocket portion located between the upper pocket portion and the lower pocket portion;
a unitary textile material extending from the upper pocket portion to the lower pocket portion, the unitary textile material constructed from a plurality of strands;
a predefined, three dimensional, concave shape that is integrally formed in the unitary textile material due to at least one of a knit structure and a weave structure being knitted or weaved respectively in a predetermined manner so as to provide the predefined, three dimensional concave shape; and
a second vertical element laterally displaced from and shorter than a first vertical element,
wherein the first vertical element includes at least 10% more rows of strands than the second vertical element,
wherein at least one of the first vertical element and the second vertical element is less than 15 needles wide.

2. The lacrosse pocket of claim 1 ,
wherein the unitary textile material includes a first layer and a second layer, one above the other, the first layer and the second layer collectively forming the first vertical element with the first layer and the second layer being connected at opposing sides via a plurality of interlooped strands.

3. The lacrosse pocket of claim 1 , comprising:
a join element extending between the first vertical element and the second vertical element,
wherein the join element is formed from at least one join strand that is interlooped with a vertical element strand of the first vertical element.

4. The lacrosse pocket of claim 1 ,
wherein the unitary textile material includes a first layer and a second layer, one above the other,
wherein each of the first layer and the second layer are integrally formed in the unitary textile material,
wherein the first layer and second layer form a portion of a first tube having an open space between the first layer and the second layer.

5. The lacrosse pocket of claim 4 ,
wherein the first layer and second layer each include opposing sides that are integrally knitted with the first layer and the second layer, such that the first layer, second layer and opposing sides include a plurality of interlooped strands that collectively form the first vertical element,
wherein at least one of the opposing sides transitions to a join element.

6. The lacrosse pocket of claim 1 ,
wherein at least one of the first vertical element and the second vertical element is less than 10 needles wide.

7. The lacrosse pocket of claim 6 ,
wherein at least one of the first vertical element and the second vertical element is less than 8 needles wide.

8. The lacrosse pocket of claim 7 ,
wherein at least one of the first vertical element and the second vertical element is less than 7 needles wide.

9. The lacrosse pocket of claim 1 ,
wherein at least one of the first vertical element and the second vertical element is between 5 and 10 needles wide.

10. The lacrosse pocket of claim 1 ,
wherein the first vertical element includes at least 25% more rows than the second vertical element.

11. A lacrosse pocket comprising:
a unitary textile material having a plurality of at least one of knitted strands and weaved strands;
a predefined, three dimensional, concave shape that is integrally formed in the lacrosse pocket due to at least one of a knit structure and a weave structure being knitted or weaved respectively in a predetermined manner so as to provide the predefined, three dimensional concave shape; and
a pocket body bounded by a perimeter flange constructed from the plurality of at least one of knitted strands and weaved strands and formed integrally with the pocket body,
wherein the pocket defines a longitudinal axis centered between a first side edge and a second side edge of the lacrosse pocket,
wherein a plurality of vertical elements become progressively shorter in a length measured parallel to the longitudinal axis the farther a vertical element is located away from the longitudinal axis,
wherein each of the plurality of vertical elements includes a plurality of rows of strands therein, a number of rows of strands in each vertical element decreasing the farther a vertical element is located away from the longitudinal axis,
wherein the length of, and the number of rows in, the plurality of vertical elements enable the vertical elements to collectively cooperate with one another to form a side-to-side concave curvature of the lacrosse pocket, the concave curvature contributing to the predefined, three dimensional, concave shape that is integrally formed in the lacrosse pocket,
wherein the plurality of vertical elements includes a first vertical element and a second vertical element,
wherein the first vertical element includes at least 5% more rows of strands than the second vertical element,
wherein at least one of the first vertical element and the second vertical element is less than 15 needles wide.

12. The lacrosse pocket of claim 11 ,
wherein the first vertical element includes at least 10% more rows of strands than the second vertical element,
wherein at least one of the first vertical element and the second vertical element is less than 10 needles wide.

13. The lacrosse pocket of claim 11 , comprising:
a bullseye opening that is larger than any other opening in the pocket body,
wherein the bullseye opening includes a geometric center,
wherein the geometric center is aligned with an apex of the predefined, three dimensional, concave shape that is integrally formed in the lacrosse pocket.

14. The lacrosse pocket of claim 11 ,
wherein the perimeter flange includes the knitted strands constructed from a polyamide and the pocket body inside the perimeter flange includes knitted strands constructed from a different thermoplastic polymer than polyamide.

15. The lacrosse pocket of claim 11 ,
wherein the perimeter flange includes a width extending outward from the pocket body with which it is integrally formed,

wherein the width configured to provide an adequate surface area to join the pocket body to the lacrosse head,
wherein the perimeter flange includes a first plurality of knitted strands having a first modulus of elasticity,
wherein the pocket body inside the perimeter flange includes a second plurality of knitted strands having a second modulus of elasticity that is less than the first modulus of elasticity so that the first knitted strands dampen rebound of the lacrosse pocket upon capture of a lacrosse ball.

16. The lacrosse head of claim 15 ,
wherein the first plurality of knitted strands are constructed from a first material selected from the group consisting of an aromatic polyamide and an ultra-high molecular weight polyethylene,
wherein the second plurality of knitted strands are constructed from a second material selected from the group consisting of a high strength polyethylene, a polypropylene and a polyethylene multi-fiber yarn.

17. The lacrosse pocket of claim 11 , comprising:
a plurality of join elements between the first and second vertical elements, the join elements and the first and second vertical elements forming a plurality of openings,
wherein the openings become progressively smaller from an upper pocket portion toward a lower pocket portion.
