Abstract

An upper component for an article of footwear allows easy entry of the foot into the article of footwear. The upper component includes a heel body, which includes a first portion partially defining an ankle opening. The heel body further includes a second portion coupled to the first portion. The second portion is foldable and partially defines the ankle opening. The second portion is movable relative to the first portion between an unfolded configuration and a folded configuration. The upper component includes at least one tension member coupled to the second portion. The tension member is movable relative to the first portion to move the second portion from the unfolded configuration to the folded configuration. The ankle opening is larger when the second portion is in the unfolded configuration than when the second portion is in the folded configuration.

First claim

The invention claimed is:

1. An upper component for an article of footwear, comprising:
a heel body including:
a first portion partially defining an ankle opening;
a second portion coupled to the first portion, wherein the second portion is foldable and partially defines the ankle opening, and the second portion is movable relative to the first portion between an unfolded configuration and a folded configuration;

at least one tension member coupled to the second portion, wherein the at least one tension member is movable relative to the first portion to move the second portion from the unfolded configuration to the folded configuration;
wherein the ankle opening is larger when the second portion is in the unfolded configuration than when the second portion is in the folded configuration; and
wherein:
the second portion includes a plurality of fold areas to allow the second portion to move between the unfolded configuration and the folded configuration;
each of the fold areas has a substantially linear shape;
the second portion includes a plurality of panels;
the heel body further includes a plurality of elongated polymeric bodies coupled to the panels;
each of the elongated polymeric bodies is disposed adjacent a respective one of the fold areas; and
each of the elongated polymeric bodies is substantially parallel to the respective one of the fold areas.

2. The upper component of claim 1 , further comprising a tube partly disposed inside the first portion, wherein:
the at least one tension member is disposed in the tube to minimize friction between the at least one tension member and the heel body when the tension member moves relative to the first portion.

3. The upper component of claim 1 , wherein:
the second portion includes a medial foldable side and a lateral foldable side;
the at least one tension member includes a first string segment coupled to the second portion at the foldable lateral side;
the at least one tension member includes a second string segment coupled to the second portion at the foldable medial side;
the at least one tension member includes a third string segment interconnecting the first string segment and the second string segment; and
the third string segment is disposed outside the heel body to allow a wearer to manually pull the third string segment to move the second portion from the unfolded configuration to the folded configuration.

4. The upper component of claim 1 in combination with a sole structure, further comprising a spool assembly coupled to the sole structure, wherein:
the spool assembly is coupled to the at least one tension member to move the second portion between the unfolded configuration and the folded configuration.

5. The upper component of claim 4 , wherein:
the sole structure includes a sole forefoot portion, a sole heel portion, and a sole midfoot portion between the sole forefoot portion and the sole heel portion; and
the spool assembly is coupled to the sole midfoot portion.

6. The upper component of claim 4 , wherein the spool assembly further includes:
a spool rotatable about an axis to wind and unwind the at least one tension member; and
an electric motor coupled to the spool such that the spool rotates about the axis upon activation of the electric motor.

7. The upper component of claim 6 , further comprising a remote control in wireless communication with the electric motor to control an operation of the electric motor.

8. The upper component of claim 1 , further comprising a sensor to sense a wearer's foot inside the heel body.

9. The upper component of claim 8 in combination with a sole structure, wherein:
the sole structure includes a sole forefoot portion, a sole heel portion, and a sole midfoot portion between the sole forefoot portion and the sole heel portion; and
the sensor is a pressure sensor coupled to the sole heel portion to sense a pressure exerted by a foot when the foot is inside the heel body.

10. The upper component of claim 1 , wherein:
the fold areas are disposed between the panels; and
the fold areas are thinner than the panels.

11. An article of footwear, comprising:
a sole structure;
an upper component coupled to the sole structure, wherein the upper component includes a heel body, and the heel body includes:
a first portion partially defining an ankle opening;
a second portion coupled to the first portion, wherein the second portion is foldable and partially defines the ankle opening, the second portion is movable relative to the first portion between an unfolded configuration and a folded configuration, the second portion includes a plurality of fold areas to allow the second portion to move between the unfolded configuration and the folded configuration, and the second portion includes a plurality of panels;
at least one tension member coupled to the second portion, wherein the at least one tension member is movable relative to the first portion to move the second portion from the unfolded configuration to the folded configuration;
a plurality of elongated polymeric bodies coupled to the panels, wherein each of the elongated polymeric bodies is disposed adjacent a respective one of the fold areas; and
wherein the ankle opening is larger when the second portion is in the unfolded configuration than when the second portion is in the folded configuration.

12. The article of footwear of claim 11 , further comprising a tube partly disposed inside the first portion, wherein:
the at least one tension member is disposed in the tube to minimize friction between the at least one tension member and the heel body when the tension member moves relative to the first portion.

13. The article of footwear of claim 11 , wherein:
the second portion includes a medial foldable side and a lateral foldable side;
the at least one tension member includes a first string segment coupled to the second portion at the lateral foldable side;
the at least one tension member includes a second string segment coupled to the second portion at the medial foldable side;
the at least one tension member includes a third string segment interconnecting the first string segment and the second string segment; and
the third string segment is disposed outside the heel body to allow a wearer to manually pull the third string segment to move the second portion from the unfolded configuration to the folded configuration.

14. The article of footwear of claim 11 , further comprising a spool assembly coupled to the sole structure, wherein:
the spool assembly is coupled to the at least one tension member to move the second portion between the unfolded configuration and the folded configuration.

15. The article of footwear of claim 14 , wherein:
the sole structure includes a sole forefoot portion, a sole heel portion, and a sole midfoot portion between the sole forefoot portion and the sole heel portion;
the spool assembly is coupled to the sole midfoot portion;
the spool assembly further includes:
a spool rotatable about an axis to wind and unwind the at least one tension member; and
an electric motor coupled to the spool such that the spool rotates about the axis upon activation of the electric motor.

16. The article of footwear of claim 15 , further comprising a remote control in wireless communication with the electric motor to control an operation of the electric motor.

17. The article of footwear of claim 11 , further comprising a biasing member coupled to the second portion to bias the second portion toward the unfolded configuration.
