Abstract

An article of footwear includes a sole structure, an upper attached to the sole structure, and a lacing system. The lacing system includes a housing disposed on a tongue of the upper, a lateral side flap and a medial side flap that extend from the sole structure along lateral and medial sides of the upper, respectively, toward the tongue, a plurality of lateral lace retainers disposed along an upper end of the lateral side flap, a plurality of medial lace retainers disposed along an upper end of the medial side flap, and a lace that extends from the housing through the pluralities of lateral and medial lace retainers in a crisscrossing manner across the tongue.

First claim

We claim:

1. An article of footwear, comprising:
a sole structure;
an upper attached to the sole structure, the upper comprising a lateral side, a medial side, and a tongue;
a lacing system comprising:
a housing disposed on the tongue;
a lateral side flap extending from the sole structure and along the lateral side of the upper toward the tongue, such that an upper end of the lateral side flap is next to a lateral side of the tongue and is pivotably moveable relative to the lateral side of the upper;
a medial side flap extending from the sole structure and along the medial side of the upper toward the tongue, such that an upper end of the medial side flap is next to a medial side of the tongue and is pivotably moveable relative to the medial side of the upper;
a plurality of lateral lace retainers disposed along the upper end of the lateral side flap, and a plurality of medial lace retainers disposed along the upper end of the medial side flap; and
a lace that extends from the housing through the pluralities of lateral and medial lace retainers in a crisscrossing manner across the tongue,

wherein the housing is configured to draw the lace into the housing;
a motor and a gear train including a wheel gear disposed within a base of the housing; and
an upper extension of the wheel gear disposed on a base cover of the housing, the upper extension of the wheel gear configured to receive a portion of the lace received through a lateral aperture and a medial aperture that are defined by a top cover of the housing,

wherein when the motor drives the gear train, the lace is drawn into the housing.

2. The article of footwear of claim 1 , wherein the housing defines a lateral aperture and a medial aperture, and
wherein the lace extends through the lateral aperture, the medial aperture, the plurality of lateral lace retainers, and the plurality of medial lace retainers.

3. The article of footwear of claim 2 , wherein the plurality of lateral lace retainers includes a first lateral lace retainer, a second lateral lace retainer, and a third lateral lace retainer,
wherein the plurality of medial lace retainers includes a first medial lace retainer, a second medial lace retainer, and a third medial lace retainer, and
wherein the lace extends from the housing through the lateral aperture of the housing, through the first lateral lace retainer, across the tongue and through the second medial lace retainer, across the tongue again and through the third lateral lace retainer, across the tongue again and through the third medial lace retainer, across the tongue again and through the second lateral lace retainer, across the tongue again and through the first medial lace retainer, and back into the housing through the medial aperture of the housing.

4. The article of footwear of claim 3 , wherein the tongue defines a plurality of lace channels and a housing recess that is configured to receive the housing, and
wherein the plurality of lace channels is configured to receive portions of the lace extending from the lateral and medial apertures of the housing and the plurality of lateral lace retainers and the plurality of medial lace retainers.

5. The article of footwear of claim 3 , wherein the plurality of lateral lace retainers and the plurality of medial lace retainers include an elongated lace aperture configured to retain portions of the lace extending through the lateral and medial lace retainers at an angle relative to the portions of the lace extending from the lateral and medial lace retainers across the tongue.

6. The article of footwear of claim 1 , wherein, when the lace is drawn into the housing, the upper end of the lateral side flap is pulled inward toward the tongue by the plurality of lateral lace retainers, the upper end of the medial side flap is pulled inward toward the tongue by the plurality of medial lace retainers, and the tongue is pulled downward toward the sole structure.

7. The article of footwear of claim 1 , wherein the lacing system further comprises a controller disposed within the sole structure, the controller including a battery, and
wherein the controller is electrically connected to the housing and powers the motor.

8. The article of footwear of claim 7 , wherein the lacing system further comprises a swipe sensor disposed on the base cover of the housing and along a panel of the top cover of the housing, the swipe sensor being powered by the battery of the controller and operable to receive user inputs.

9. The article of footwear of claim 7 , wherein the controller is removable from the sole structure via an opening in the upper of the article of footwear.

10. An article of footwear, comprising:
a sole structure;
an upper attached to the sole structure, the upper comprising a tongue; and
a lacing system comprising:
a housing disposed on the tongue and next to an instep region of the upper;
a plurality of lateral lace retainers disposed on the upper along a lateral side of the tongue, and a plurality of medial lace retainers disposed on the upper along a medial side of the tongue; and
a lace that extends from the housing through a lateral aperture and a medial aperture of the housing and through the pluralities of lateral and medial lace retainers in a crisscrossing manner across the tongue, the housing being configured to draw the lace into the housing,

wherein the tongue defines a housing recess configured to receive the housing and a plurality of tongue lace channels configured to receive portions of the lace extending though the pluralities of lateral and medial lace retainers,
wherein the housing recess and the plurality of tongue lace channels extend from an outer surface of the tongue to an intermediate surface of the tongue,
wherein the housing defines a housing lace channel configured to receive two or more portions of the lace extending between the pluralities of lateral and medial lace retainers,
wherein the lacing system further comprises a controller disposed within the sole structure, the controller being electrically connected to the housing,
wherein the lacing system further comprises:
a motor electrically connected to and powered by a battery of the controller; and
a gear train including a wheel gear, the wheel gear including an upper extension,

wherein the motor and the gear train are disposed within a base of the housing, and the upper extension of the wheel gear is disposed on a base cover of the housing,
wherein the upper extension of the wheel gear includes an aperture configured to receive a portion of the lace that is received through a lateral aperture and a medial aperture defined by a top cover of the housing, and
wherein, when the motor drives the gear train, the lace is drawn into the housing.

11. The article of footwear of claim 10 , wherein when the lace is drawn into the housing, the tongue is pulled downward, toward the sole structure.

12. The article of footwear of claim 10 , wherein
the plurality of tongue lace channels is configured to receive portions of the lace extending from the pluralities of lateral and medial lace retainers and the housing lace channel.

13. The article of footwear of claim 10 , wherein the lace is a closed loop lace.

14. An article of footwear, comprising:
a sole structure, including an insole, a midsole, and an outsole;
an upper attached to the sole structure; and
a lacing system, comprising:
a housing disposed on the upper and next to an instep region of the upper;
a lateral side flap extending from the sole structure and along a lateral side of the upper toward the housing, such that an upper end of the lateral s
