Abstract

Foot support systems include a fluid flow control system that facilitates movement of fluid into, out of, and/or within a sole structure and/or article of footwear, e.g., to change and/or control pressure in fluid filled bladder(s). The fluid flow control system includes: (a) a manifold body defining an internal chamber; (b) at least a first port in fluid communication with the internal chamber; (c) at least a first valve (including a first valve activator) controlling fluid flow through the first port; and (d) a movable cam at least partially within the internal chamber. Valve activator surface(s) on the cam interact with the valve activator(s) to selectively open and close valve(s) based on cam positioning.

First claim

What is claimed is:

1. A footwear foot support system, comprising:
a foot support bladder;
a fluid source container;
a manifold body defining an internal chamber;
a first port placing the fluid source container in fluid communication with the internal chamber;
a second port placing the foot support bladder in fluid communication with the internal chamber;
a third port in fluid communication with the internal chamber and with an external environment;
a first valve controlling fluid flow between the internal chamber and the fluid source container through the first port, wherein the first valve includes a first valve activator;
a second valve controlling fluid flow between the internal chamber and the foot support bladder through the second port, wherein the second valve includes a second valve activator;
a third valve controlling fluid flow between the internal chamber and the external environment through the third port, wherein the third valve includes a third valve activator;
a movable cam at least partially located within the internal chamber, wherein the movable cam includes: (a) one or more first valve activator surfaces that interact with the first valve activator to change the first valve between a closed configuration and an open configuration when the movable cam is moved, (b) one or more second valve activator surfaces that interact with the second valve activator to change the second valve between a closed configuration and an open configuration when the movable cam is moved, and (c) one or more third valve activator surfaces that interact with the third valve activator to change the third valve between a closed configuration and an open configuration when the movable cam is moved.

2. The footwear foot support system according to claim 1 , wherein, in at least one position of the movable cam, the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces are longitudinally and circumferentially spaced with respect to one another and with respect to the first valve activator, the second valve activator, and the third valve activator such that: (a) none of the one or more first valve activator surfaces interacts with the first valve activator to thereby place the first valve in the closed configuration, (b) none of the one or more second valve activator surfaces interacts with the second valve activator to thereby place the second valve in the closed configuration, and (c) none of the one or more third valve activator surfaces interacts with the third valve activator to thereby place the third valve in the closed configuration.

3. The footwear foot support system according to claim 1 , wherein, in at least one position of the movable cam, the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces are longitudinally and circumferentially spaced with respect to one another and with respect to the first valve activator, the second valve activator, and the third valve activator such that: (a) none of the one or more first valve activator surfaces interacts with the first valve activator to thereby place the first valve in the closed configuration, (b) none of the one or more second valve activator surfaces interacts with the second valve activator to thereby place the second valve in the closed configuration, and (c) at least one of the one or more third valve activator surfaces interacts with the third valve activator to thereby place the third valve in the open configuration and to thereby place the internal chamber of the manifold body in fluid communication with the external environment.

4. The footwear foot support system according to claim 1 , wherein at least one position of the movable cam is a foot support/external environment fluid exchange configuration in which the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces are longitudinally and circumferentially spaced with respect to one another and with respect to the first valve activator, the second valve activator, and the third valve activator such that: (a) none of the one or more first valve activator surfaces interacts with the first valve activator to thereby place the first valve in the closed configuration, (b) at least one of the one or more second valve activator surfaces interacts with the second valve activator to thereby place the second valve in the open configuration, and (c) at least one of the one or more third valve activator surfaces interacts with the third valve activator to thereby place the third valve in the open configuration and to thereby place the foot support bladder and the external environment in fluid communication with one another.

5. The footwear foot support system according to claim 1 , wherein at least one position of the movable cam is a fluid source/foot support fluid exchange configuration in which the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces are longitudinally and circumferentially spaced with respect to one another such that: (a) at least one of the one or more first valve activator surfaces interacts with the first valve activator to thereby place the first valve in the open configuration, (b) at least one of the one or more second valve activator surfaces interacts with the second valve activator to thereby place the second valve in the open configuration, and (c) none of the one or more third valve activator surfaces interacts with the third valve activator to thereby place the third valve in the closed configuration and to thereby place the fluid source container and the foot support bladder in fluid communication with one another.

6. The footwear foot support system according to claim 1 , wherein at least one position of the movable cam is a fluid source/external environment fluid exchange configuration in which the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces are longitudinally and circumferentially spaced with respect to one another such that: (a) at least one of the one or more first valve activator surfaces interacts with the first valve activator to thereby place the first valve in the open configuration, (b) none of the one or more second valve activator surfaces interacts with the second valve activator to thereby place the second valve in the closed configuration, and (c) at least one of the one or more third valve activator surfaces interacts with the third valve activator to thereby place the third valve in the open configuration and to thereby place the fluid source container and the external environment in fluid communication with one another.

7. The footwear foot support system according to claim 1 , further comprising:
a motor operatively coupled with the movable cam to rotate or otherwise move the movable cam to place the one or more first valve activator surfaces, the one or more second valve activator surfaces, and the one or more third valve activator surfaces in a plurality of different positions with respect to the internal chamber of the manifold body.

8. The footwear foot support system according to claim 1 , wherein the fluid source container includes at least one of: a compressor, a fluid filled reservoir for containing gas, or a fluid filled bladder.

9. The footwear foot support system according to claim 1 , wherein in a first position of the movable cam, the one or more first valve activator surfaces, the one or more second valve activator surfaces, and
