Abstract

A method of making a sole for an article of footwear is disclosed. The method includes steps of attaching a double sided acrylic adhesive film to a composite plate. The composite plate is then attached to an outer member of the article of footwear using the acrylic adhesive film.

First claim

The invention claimed is:

1. A method of making a sole for an article of footwear, comprising:
manufacturing a composite plate by forming a laminate by bonding a first side of a composite-plate-to-midsole adhesive to a first side of a composite sheet, wherein the composite plate is disposed between an outer member and a midsole, the outer member having an inner portion and the midsole having a lower portion facing the inner portion of the outer member, and wherein the composite plate covers a first portion of the inner portion of the outer member, leaving a remaining second portion of the inner portion of the outer member and further wherein the composite plate covers a first portion of the lower portion of the midsole, leaving a remaining second portion of the lower portion of the midsole;
attaching the first portion of the lower portion of the midsole to the composite plate via the composite-plate-to-midsole adhesive;
applying a midsole-to-outer-member adhesive between the remaining second portion of the lower portion of the midsole and the remaining second portion of the inner portion of the outer member; and
attaching the remaining second portion of the lower portion of the midsole and the remaining second portion of the inner portion of the outer member via the midsole-to-outer-member adhesive,
wherein the composite plate has an outer perimeter and the outer perimeter is located entirely within an arch portion, and further wherein the composite plate has a contoured shape having a shape of the arch portion by having a first flat portion, an arched second portion, and a third flat portion.

2. The method according to claim 1 , wherein the composite plate comprises pre-peg woven sheets of carbon fibers.

3. The method according to claim 1 , further comprising:
applying a composite-plate-to-outer-member adhesive disposed between the composite plate and the first portion of the inner portion of the outer member; and
attaching the composite plate and the first portion of the inner portion of the outer member via the composite-plate-to-outer-member adhesive.

4. The method according to claim 3 , wherein the composite-plate-to-outer-member adhesive comprises an adhesive film.

5. The method according to claim 3 , wherein the composite-plate-to-midsole adhesive comprises:
a film having a first side facing the composite plate and a second side opposite to the first side,
an adhesive disposed on the first side, and
an adhesive disposed on the second side,
wherein the midsole-to-outer-member adhesive is used in conjunction with a solvent.

6. The method according to claim 5 , wherein the composite-plate-to-midsole adhesive is an acrylic based adhesive film.

7. The method according to claim 5 , wherein the midsole-to-outer-member adhesive further comprises a primer applied to the first portion of the inner portion of the outer member.

8. The method according to claim 3 , wherein the composite-plate-to-outer-member adhesive comprises a double sided acrylic based adhesive film and the midsole-to-outer-member adhesive is used in conjunction with a solvent.

9. The method according to claim 1 , wherein the lower portion of the midsole defines a recess shaped and configured to receive a portion of the composite plate protruding above the remaining second portion of the inner portion of the outer member; and wherein the composite-plate-to-midsole adhesive is discontinuous with the midsole-to-outer-member adhesive.

10. The method according to claim 4 , wherein the inner portion of the outer member defines a recess shaped and configured to receive a portion of the composite plate protruding below the remaining second portion of the lower portion of the midsole; and wherein the composite-plate-to-outer-member adhesive is discontinuous with the midsole-to-outer-member adhesive.

11. The method according to claim 4 , wherein the composite-plate-to-midsole adhesive and the composite-plate-to-outer-member adhesive are disposed on horizontal planes different from a horizontal plane on which the midsole-to-outer-member adhesive is disposed.

12. The method according to claim 1 , wherein the composite-plate-to-midsole adhesive continuously bonds the composite plate to the first portion of the lower portion of the midsole across an entirety of a top face of the composite plate.

13. A method of making a sole for an article of footwear, comprising:
manufacturing a composite plate by forming a laminate by applying a first side of a composite-plate-to-midsole adhesive to a first side of a composite sheet, wherein the composite plate is disposed between an outer member and a midsole, wherein the composite plate covers a first portion of an upper portion of the outer member, leaving a remaining second portion of the upper portion of the outer member and further wherein the composite plate covers a first portion of a lower portion of the midsole, leaving a remaining second portion of the lower portion of the midsole;
applying a composite-plate-to-outer-member adhesive disposed between the composite plate and the first portion of the upper portion of the outer member;
attaching the first portion of the upper portion of the outer member to the composite plate via the composite-plate-to-outer-member adhesive;
attaching the first portion of the lower portion of the midsole to the composite plate via the composite-plate-to-midsole adhesive;
applying a midsole-to-outer-member adhesive between the remaining second portion of the lower portion of the midsole and the remaining second portion of the upper portion of the outer member; and
attaching the remaining second portion of the lower portion of the midsole and the remaining second portion of the upper portion of the outer member via the midsole-to-outer-member adhesive,
wherein the composite plate has an outer perimeter, wherein the outer perimeter is located entirely within an arch portion, and wherein the composite plate has a contoured shape having a shape of the arch portion by having a first flat portion, an arched second portion, and a third flat portion.

14. The method according to claim 13 , wherein the composite-plate-to-outer-member adhesive continuously bonds the composite plate to the first portion of the upper portion of the outer member across an entirety of a bottom face of the composite plate; and wherein the composite-plate-to-midsole adhesive continuously bonds the composite plate to the first portion of the lower portion of the midsole across an entirety of a top face of the composite plate.

15. The method according to claim 13 , wherein the composite-plate-to-outer-member adhesive and the composite-plate-to-midsole adhesive each comprises:
a film having a first side facing the composite plate and a second side opposite to the first side,
an adhesive disposed on the first side, and
an adhesive disposed on the second side,
wherein the midsole-to-outer-member adhesive comprises is used in conjunction with a solvent.

16. A method of making a sole for an article of footwear, comprising:
manufacturing a composite plate by forming a laminate by bonding a first side of a composite-plate-to-midsole adhesive to a first side of a composite sheet, wherein the composite plate is disposed between an outer member and a midsole, the outer member having an inner portion and the midsole having a lower portion facing the inner portion of the outer member, and wherein the composite plate covers a first portion of the inner portion of the outer member, leaving a remaining second portion of the inner portion of the outer member and further wherein the composite plate covers
