Abstract

An article of footwear with a dynamic support system that controls arrays of tiles in the upper of the footwear to adjust the level of support provided in different regions of the upper. Sensors in the sole of the footwear, in the upper of the footwear and/or in an article worn by the wearer of the footwear measure the level of stress or other characteristics and provide input to one or more microprocessors that control motors located in the sole or in the upper of the footwear. When the motors are activated, they may compress or loosen arrays of tiles to adjust the stiffness of the upper in one or more regions of the upper.

First claim

What is claimed is:

1. An article of footwear comprising:
a sole;
an upper, the upper including an interior layer and an exterior layer;
a microprocessor;
a sensor in communication with the microprocessor, wherein the sensor is embedded in at least one of the sole and the upper;
an array of tiles, located between the interior layer and the exterior layer of the upper, forming a plurality of rows and a plurality of columns; a first tile of the array of tiles having a first diagonal and a second diagonal crossing the first diagonal, the first tile including:
a first passageway extending along the first diagonal; and
a second passageway extending along the second diagonal;
a first cable positioned in the first passageway and mechanically connected to a reel coupled to a motor;
a second cable positioned in the second passageway and mechanically connected to the reel;
wherein the microprocessor is configured to receive an input from sensor and control the reversible motor to rotate the reel to compress the array of tiles according to the input received from the sensor.

2. The article of footwear of claim 1 , wherein the first cable is one of a first set of cables and the second cable is one of a second set of cables, wherein individual cables of the first set of cables are laced through at least one of a first passage way and a second passage way of tiles of alternate rows of the plurality of rows and individual cables of the second set of cables are laced through at least one of a first passageway and a second passageway of tiles of alternate columns of the plurality of columns.

3. The article of footwear of claim 2 , wherein the individual cables of the first set of cables are laced through the first passageway of the tiles in the alternate rows and the individual cables of the second set of cables are laced through the second passageway of the tiles in the alternate columns.

4. The article of footwear of claim 1 , wherein the first passageway and the second passageway are perpendicular to each other.

5. The article of footwear of claim 1 , wherein the first passageway extends over and does not intersect the second passageway.

6. The article of footwear of claim 1 , wherein the first passageway is spaced from the second passageway in a direction normal to a surface of the first tile that is adjacent to the interior surface.

7. The article of footwear of claim 1 , wherein the first passageway intersects the second passageway at a middle portion of the first tile.

8. An article of footwear comprising:
a sole;
an upper including first layer and a second layer;
a microprocessor;
a sensor in communication with the microprocessor, wherein the sensor is embedded in at least one of the sole and the upper;
an array of tiles, located between the interior layer and the exterior layer of the upper, forming a plurality of rows and a plurality of columns, a first tile of the array of tiles including a first major surface, a second major surface, and a passageway extending therethrough;
a first cable positioned in the passageway and coupled to a reel coupled to a motor;
a second cable positioned in between the first surface of the tile and the first layer of the upper and coupled to the reel;
wherein the microprocessor is configured to receive an input from the sensor and control the motor to rotate the reel to compress the array of tiles according to the input received from the sensor.

9. The article of footwear of claim 8 , wherein the first cable extends along the rows of tiles and the second cable extends along the columns of tiles.

10. The article of footwear of claim 8 , wherein the first passageway extends through a first vertex and a diagonal second vertex of the first tile.

11. The article of footwear of claim 10 , wherein the second cable extends adjacent to a third vertex and a diagonal fourth vertex of the tile.

12. The article of footwear of claim 8 , wherein the first cable is spaced from the second cable in a direction normal to the first surface of the tile.

13. The article of footwear of claim 8 , wherein at least one of the first cable and the second cable is laced through alternate columns and alternate rows of tiles.

14. A method, comprising:
securing and upper to a sole of an article of footwear, the upper including an interior layer and an exterior layer;
securing a microprocessor to one of the upper and the sole;
coupling a sensor in communication with the microprocessor, wherein the sensor is embedded in at least one of the sole and the upper;
securing an array of tiles between the interior layer and the exterior layer of the upper, forming a plurality of rows and a plurality of columns, a first tile of the array of tiles having a first diagonal and a second diagonal crossing the first diagonal, the first tile including:
a first passageway extending along the first diagonal; and
a second passageway extending along the second diagonal;
lacing a first cable through the first passageway and mechanically connecting the first cable to a reel coupled to a motor;
lacing a second cable in the second passageway and mechanically connecting the second cable to the reel;
wherein the microprocessor is configured to receive an input from sensor and control the reversible motor to rotate the reel to compress the array of tiles according to the input received from the sensor.

15. The method of claim 14 , wherein the first cable is one of a first set of cables and the second cable is one of a second set of cables, further comprising:
lacing individual cables of the first set of cables through at least one of a first passage way and a second passage way of tiles of alternate rows of the plurality of rows; and
lacing individual cables of the second set of cables through at least one of a first passageway and a second passageway of tiles of alternate columns of the plurality of columns.

16. The method of claim 15 , wherein lacing the individual cables of the first set of cables includes lacing the individual cables of the first set of cables through the first passageway of the tiles in the alternate rows and lacing the individual cables of the second set of cables includes lacing the cables of the second set of cables through the second passageway of the tiles in the alternate columns.

17. The method of claim 14 , wherein the first passageway and the second passageway are approximately perpendicular to each other.

18. The method of claim 14 , wherein the first passageway extends over and does not intersect the second passageway.

19. The method of claim 14 , wherein the first passageway is spaced from the second passageway in a direction normal to a surface of the first tile that is adjacent to the interior surface.

20. The method of claim 14 , wherein the first passageway intersects the second passageway at a middle portion of the first tile.
