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 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 pocket can include a perimeter flange constructed from special materials and/or a perimeter flange including intermittent voids along an outer edge so that the perimeter flange stretches when the pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the pocket when a lacrosse ball exerts force upon the pocket in the loaded state.

First claim

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

1. A method of making a lacrosse pocket comprising:
mechanically manipulating a plurality of first strands and a plurality of second strands with an automated pocket assembly machine during an automated process to form a lacrosse pocket body during the automated process, the lacrosse pocket body including a predefined, three dimensional, concave shape, the lacrosse pocket body having a lower pocket portion, an upper pocket portion and a middle pocket portion therebetween;
forming a perimeter flange in the lacrosse pocket body during the automated process, the perimeter flange including the plurality of first strands interlooped with one another,
forming at least one of the lower pocket portion, the upper pocket portion, and the middle pocket portion of the lacrosse pocket body with the plurality of second strands interlooped with one another, and with ones of the plurality of first strands so that the perimeter flange and at least one of the lower pocket portion, the upper pocket portion, and the middle pocket portion form a unitary textile material,
wherein the plurality of first strands are constructed from a first material that is polyamide 6,6 and are in the form of a first yarn having a plurality of first twisted filaments, the first yarn having a tenacity of 7 g-f/denier to 10 g-f/denier, the first material having an elongation at break of between 30% and 50%,
wherein the perimeter flange includes an edge width of 2.5 mm to 15.0 mm when the lacrosse pocket body is in an unloaded state, without a lacrosse ball therein,
wherein the perimeter flange with its first yarn is configured to stretch so that the edge width increases at least 2.5% when the lacrosse pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the lacrosse pocket body when a lacrosse ball exerts force upon the lacrosse pocket body in the loaded state.

2. The method of claim 1 , comprising:
mechanically manipulating the plurality of first strands so the perimeter flange substantially surrounds the lacrosse pocket body,
wherein the at least one of the lower pocket portion, the upper pocket portion, and the middle pocket portion inside the perimeter flange is constructed from the plurality of second strands which are constructed from a second material, first individual ones of the plurality of second strands being in the form of a second yarn having a plurality of second twisted filaments, the second yarn having an elongation at break of between 10% and 30%.

3. The method of claim 2 ,
wherein second individual ones of the plurality of second strands are constructed from a third material that is polyethylene and are in the form of a third yarn having a plurality of third twisted filaments, the third yarn having an elongation at break of between 5% and 25%.

4. The method of claim 3 comprising:
mechanically manipulating the third yarn to produce first and second runner elements disposed on opposite sides of a longitudinal axis of the lacrosse pocket body.

5. The method of claim 4 comprising:
mechanically manipulating the second yarn to produce a first side portion between the first runner element and the perimeter flange, and a second side portion between the second runner element and the perimeter flange.

6. The method of claim 1 , comprising: wherein the density of the first yarn is between 0.90 g/cm3 and 1.2 g·cm3.

7. A method of manufacturing a lacrosse pocket comprising:
mechanically manipulating a plurality of first strands and a plurality of second strands with an automated pocket assembly machine during an automated process to form a lacrosse pocket body during the automated process, the lacrosse pocket body including a predefined, three dimensional, concave shape, the lacrosse pocket body having a lower pocket portion, an upper pocket portion and a middle pocket portion therebetween;
forming a perimeter flange in the pocket body during the automated process, the perimeter flange including the plurality of first strands interlooped with one another,
forming at least one of the upper pocket portion, the lower pocket portion and the middle pocket portion to include the plurality of second strands interlooped with one another, and with ones of the plurality of first strands so that the perimeter flange and the at least one of the upper pocket portion, the lower pocket portion and the middle pocket portion form a unitary textile material, and
wherein the plurality of first strands are constructed from a first material that is polyamide 6,6 and are in the form of a first yarn having a plurality of first twisted filaments, the first yarn having tenacity of 7 g-f/denier to 10 g-f/denier,
wherein the perimeter flange includes an edge width when the lacrosse pocket body is in an unloaded state, without a lacrosse ball therein,
wherein the perimeter flange with its first yarn is configured to stretch so that the edge width increases by at least 1.0% when the lacrosse pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the lacrosse pocket body when a lacrosse ball exerts force upon the lacrosse pocket body in the loaded state.

8. The method of claim 7 , comprising:
forming the perimeter flange so the edge width is configured to increase by at least 5% when the lacrosse pocket is in the loaded state.

9. The method of claim 7 , comprising:
forming the perimeter flange so the edge width is configured to increase by 1% to 25% when the lacrosse pocket is in the loaded state.

10. A method of manufacturing a lacrosse pocket comprising:
mechanically manipulating a plurality of first strands and a plurality of second strands with an automated pocket assembly machine during an automated process to form a lacrosse pocket body during the automated process, the lacrosse pocket body including a predefined, three dimensional, concave shape, the lacrosse pocket body having a lower pocket portion, an upper pocket portion and a middle pocket portion therebetween;
forming a perimeter flange in the pocket body during the automated process, the perimeter flange including the plurality of first strands interlooped with one another, the perimeter flange including an outer edge that is intermittently interrupted by a plurality of voids defined by the perimeter flange, and defining individual ones of the plurality of voids to include a void perimeter that transitions to the outer edge and the void perimeter includes a free edge,
forming at least one of the upper pocket portion, the lower pocket portion and the middle pocket portion to include the plurality of second strands interlooped with one another, and with ones of the plurality of first strands so that the perimeter flange and the at least one of the upper pocket portion, the lower pocket portion and the middle pocket portion form a unitary textile material, and
introducing a molten polymeric material over the outer edge so that the polymeric material encapsulates and embeds within the plurality of first strands, but so that the polymeric material does not engage a portion of the free edge so that the portion of the free edge remains free.

11. The method of claim 10 , comprising:
forming the perimeter flange to include an edge width when the lacrosse pocket body is in an unloaded state, without a lacrosse ball therein,
wherein the perimeter flange with the plurality of voids is configured to stretch so that the edge width increases when the lacrosse pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the lacrosse pocket body when a lacrosse ball exerts forc
