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 method of manufacturing a lacrosse head comprising:
mechanically manipulating a plurality of strands with an automated pocket assembly machine, thereby forming a first lacrosse pocket including the plurality of strands, the first lacrosse pocket including a three dimensional concave contour upon formation, a longitudinal axis, and the plurality of vertical elements, with the plurality of vertical elements including a first vertical element near the longitudinal axis, and a second vertical element spaced laterally away from the longitudinal axis, farther from the longitudinal axis than the first vertical element, with the second vertical element being shorter upon formation of the first lacrosse pocket than the first vertical element upon formation of the first lacrosse pocket;
placing a portion of the first lacrosse pocket in a mold cavity, the mold cavity corresponding to a lacrosse head having sidewalls joined with a scoop and a base;
introducing a molten polymeric material into the mold cavity so that the molten polymeric material is securely joined with the plurality of strands in the portion;
curing the molten polymeric material to form a cured first lacrosse head; and
removing the cured first lacrosse head from the mold cavity with the first lacrosse pocket attached to the cured lacrosse head.

2. The method of claim 1 ,
wherein the mechanical manipulation includes knitting the plurality of strands so that first strands are interlooped with second strands,
wherein the molten polymeric material surrounds the first strands and the second strands during the introducing step.

3. The method of claim 1 , comprising forming the first vertical element and the second vertical element to extend from adjacent a lower edge of the first lacrosse pocket toward an upper edge of the first lacrosse pocket.

4. The method of claim 1 comprising forming the first vertical element and the second vertical element to cooperatively form a side-to-side concave curvature.

5. The method of claim 1 , wherein the automated pocket assembly machine forms a plurality of joins between the first and second vertical elements.

6. The method of claim 1 wherein the lacrosse pocket data is utilized a plurality of times to generate a plurality of substantially identical lacrosse pockets joined end-for-end with one another along a lacrosse pocket strip.

7. The method of claim 1 comprising:
utilizing the lacrosse pocket data to guide mechanical manipulation of the plurality of strands with an automated pocket assembly machine, thereby forming a second lacrosse pocket substantially identical to the first lacrosse pocket;
placing portions of the second lacrosse pocket in the mold cavity;
introducing the molten polymeric material into the mold cavity so the molten polymeric material encapsulates the portions of the second lacrosse pocket;
allowing the molten polymeric material to cure to form a cured second lacrosse head,
wherein the second lacrosse pocket is identical to the first lacrosse pocket.

8. A method of manufacturing a lacrosse head comprising:
mechanically manipulating a plurality of strands to form a first lacrosse pocket having a three dimensional concave contour upon formation, a longitudinal axis, a plurality of openings defined by the first lacrosse pocket, and a plurality of vertical elements adjacent the plurality of openings, the plurality of vertical elements being progressively shorter in length the farther a vertical element of the plurality of vertical elements is laterally disposed from the longitudinal axis;
placing a portion of the first lacrosse pocket in a mold cavity corresponding to a first lacrosse head portion;
molding polymeric material to the portion of the first lacrosse pocket so that the polymeric material is joined with the plurality of strands within the portion of the first lacrosse pocket;
curing the polymeric material to form a cured first lacrosse head portion; and
removing the cured first lacrosse head portion with the first lacrosse pocket attached thereto from the mold cavity.

9. The method of claim 8 ,
wherein the portion of the first lacrosse pocket is an elongated perimeter flange within the mold cavity, and
wherein the cured first lacrosse head portion is a lacrosse head lowermost portion.

10. The method of claim 9 comprising molding the polymeric material to the elongated perimeter within the mold cavity so that the elongated perimeter flange is molded to the lacrosse head lowermost portion, and embedded within a scoop, a pair of sidewalls and a base.

11. The method of claim 8 wherein individual ones of the plurality of strands within the portion of the first lacrosse pocket are formed from at least one of an aromatic polyamide and an ultra-high molecular weight polyethylene.

12. The method of claim 8 wherein the mechanically manipulating step includes forming the portion of the first lacrosse pocket with first strands constructed from at least one of an aromatic polyamide and an ultra-high molecular weight polyethylene.

13. The method of claim 12 , comprising forming a remainder of the first lacrosse pocket, adjacent the portion of the lacrosse pocket, with second strands constructed from a thermoplastic polymer that is different from the at least one of an aromatic polyamide and an ultra high molecular weight polyethylene.

14. The method of claim 8 , comprising:
knitting a pocket outer perimeter in the portion of the first lacrosse pocket with first strands from the plurality of strands; and
knitting the three dimensional concave contour with second strands from the plurality of strands,
wherein the first strands are constructed from at least one of an aromatic polyamide and an ultra-high molecular weight polyethylene,
wherein the second strands are constructed from a thermoplastic polymer,
wherein the first strands are interlooped with the second strands.

15. The method of claim 8 comprising:
providing a lacrosse pocket data library;
selecting lacrosse pocket data pertaining to the first lacrosse pocket;
generating a modified version of the lacrosse pocket data pertaining to the first lacrosse pocket; and
utilizing the modified version of the lacrosse pocket data during the mechanically manipulating step.

16. A method of manufacturing a lacrosse head comprising:
mechanically manipulating a plurality of strands to form a first lacrosse pocket, the first lacrosse pocket including a three dimensional concave contour upon formation, a longitudinal axis and a plurality of vertical elements being progressively shorter in length the farther the vertical elements are laterally disposed from the longitudinal axis;
overmolding a perimeter of the first lacrosse pocket, in a mold cavity having a plurality of mold surfaces corresponding to a first lacrosse head, with molten polymeric material so that the molten polymeric material is joined with the plurality of strands;
curing the molten polymeric material to form a cured first lacrosse head; and
removing the cured first lacrosse head with the first lacrosse pocket attached thereto from the mold cavity.

17. The method of claim 16 wherein the perimeter is constructed from a first material and the remainder of the first lacrosse pocket inside the perimeter is constructed from a second material that is more elastic than the first material.

18. The method of claim 16 comprising stretching the first lacrosse pocket so that at least a portion of th
