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). Aspects of this technology may relate to one or more of: (a) footwear structures in which such systems are incorporated; (b) valve stem based fluid flow transfer systems; (c) solenoid based fluid flow transfer systems; (d) user input button features; (e) air filter features; (f) fluid tube to fluid distributor connection features; (g) fluid distributor to footwear connection features; (h) valve position sensor features; (i) valve transmission features; (j) pressure control algorithm features; (k) electronic communication features; (l) system sealing features; and/or (m) pressure sensor mounting features.

First claim

What is claimed is:

1. A fluid flow control system for an article of footwear, comprising:
a fluid distributor;
a manifold including a first manifold port;
a sealing connector including: (i) a connector body including a first surface connected with the fluid distributor and a second surface connected with the manifold, (ii) a first connector fluid path defined through the connector body and extending from a first connector port located at the first surface and in fluid communication with the fluid distributor to a second connector port located at the second surface an in fluid communication with the first manifold port, (iii) a first pressure sensor mount defined in the connector body or extending from the connector body, and (iv) a first open channel extending between the first pressure sensor mount and the first connector fluid path; and
a first pressure sensor mounted at the first pressure sensor mount in a fluid tight manner.

2. The fluid flow control system according to claim 1 , wherein the manifold includes a second manifold port, wherein the sealing connector further includes: (i) a second connector fluid path defined through the connector body and extending from a third connector port located at the first surface and in fluid communication with the fluid distributor to a fourth connector port located at the second surface and in fluid communication with the second manifold port, (ii) a second pressure sensor mount defined in the connector body or extending from the connector body, and (iii) a second open channel extending between the second pressure sensor mount and the second connector fluid path, and wherein the fluid flow control system further comprises:
a second pressure sensor mounted at the second pressure sensor mount in a fluid tight manner.

3. The fluid flow control system according to claim 1 , wherein the first pressure sensor mount includes one of a raised tube extending away from a base portion of the connector body or a recess that extends into the connector body.

4. The fluid flow control system according to claim 1 , wherein the first connector fluid path defined through the connector body is formed by a first connector body component forming a first portion of the first connector fluid path and a second connector body component forming a second portion of the first connector fluid path.

5. The fluid flow control system according to claim 1 , wherein the sealing connector comprises a block of rubber or an elastomer material through with the first connector fluid path is defined, wherein the first surface and the second surface are located on opposite sides of the connector body, and wherein the connector body extends between and sealingly connects with the fluid distributor and the manifold.

6. A foot support system for an article of footwear, comprising:
a foot support bladder;
a fluid flow control system for moving fluid into and out of the foot support bladder, wherein the fluid flow control system includes:
a fluid distributor,
a manifold including a first manifold port,
a sealing connector including: (i) a connector body including a first surface connected with the fluid distributor and a second surface connected with the manifold, (ii) a first connector fluid path defined through the connector body and extending from a first connector port located at the first surface and in fluid communication with the fluid distributor to a second connector port located at the second surface and in fluid communication with the first manifold port, (iii) a first pressure sensor mount defined in the connector body or extending from the connector body, and (iv) a first open channel extending between the first pressure sensor mount and the first connector fluid path, and
a first pressure sensor mounted at the first pressure sensor mount in a fluid tight manner; and

a first fluid line connecting the foot support bladder and the manifold, the first fluid line being in fluid communication with the first manifold port.

7. The foot support system according to claim 6 , further comprising:
a fluid container; and
a second fluid line,
wherein the manifold includes a second manifold port, wherein the sealing connector further includes: (i) a second connector fluid path defined through the connector body and extending from a third connector port located at the first surface and in fluid communication with the fluid distributor to a fourth connector port located at the second surface and in fluid communication with the second manifold port, (ii) a second pressure sensor mount defined in the connector body or extending from the connector body, and (iii) a second open channel extending between the second pressure sensor mount and the second connector fluid path, and wherein the fluid flow control system further comprises a second pressure sensor mounted at the second pressure sensor mount in a fluid tight manner, and
wherein the second fluid line connects the fluid container and the manifold, the second fluid line being in fluid communication with the second manifold port.

8. The foot support system according to claim 7 , wherein the fluid flow control system is configured to move fluid from the fluid container, through the second manifold port, through the second connector fluid path, through the first connector fluid path, through the first manifold port, and into the foot support bladder.

9. The foot support system according to claim 6 , wherein the first pressure sensor mount includes a raised tube extending away from a base portion of the connector body.

10. The foot support system according to claim 6 , wherein the first pressure sensor mount includes a recess that extends into the connector body.

11. The foot support system according to claim 6 , wherein the first connector fluid path defined through the connector body is formed by a first connector body component forming a first portion of the first connector fluid path and a second connector body component forming a second portion of the first connector fluid path.

12. The foot support system according to claim 6 , wherein the sealing connector comprises a block of rubber or an elastomer material through which the first connector fluid path is defined, wherein the first surface and the second surface are located on opposite sides of the connector body, and wherein the connector body extends between and sealingly connects with the fluid distributor and the manifold.

13. An article of footwear, comprising:
