Abstract

A variable ankle supporting shoe assembly includes a shoe including a perimeter wall having a lining comprising a foamed material. A magnetorheological fluid impregnates the foamed material and is alternated between a first state wherein the foamed material is bendable and a second state wherein the magnetorheological fluid forms a rigid structure within the foamed material such that the foamed material is not bendable. The lining forms a rigid and supportive shell when the magnetorheological fluid is in the second state. An actuating system alters the magnetorheological fluid from the first state to the second state when a condition has been met. The condition is met when the actuating system detects a combination of a threshold angle and a threshold pressure has been surpassed by the sole.

Claims

1. An athletic footwear assembly configured to become rigid when a deflection event occurs to prevent injury to a person'"'"'s ankle, said assembly comprising:

a shoe including a sole and a perimeter wall being attached to and extending upwardly from said sole, said perimeter wall being configured to receive a foot, said sole having a top side, a bottom side and a perimeter edge extending between said top and bottom sides, said perimeter wall including a vamp, heel panel and an upper;

said perimeter wall including a lining comprising a foamed material;

a magnetorheological fluid impregnating said foamed material, said magnetorheological fluid being configured to be alternated between a first state wherein said foamed material is bendable and a second state wherein said magnetorheological fluid forms rigid columns within said foamed material such that said foamed material is not bendable, said lining forming a rigid and supportive shell when said magnetorheological fluid is in said second state; and

an actuating system being mounted on said shoe and being in operational communication with said magnetorheological fluid, said actuating system altering said magnetorheological fluid from said first state to said second state when a condition has been met, said condition being met when said actuating system detects a combination of a threshold angle and a threshold pressure having been surpassed by said sole.

2. The athletic footwear assembly according to claim 1, wherein said foamed material is porous and resiliently compressible.

3. The athletic footwear assembly according to claim 1, wherein said actuating system altering said magnetorheological fluid from said second state to said first state when a deactivation event occurs.

4. The athletic footwear assembly according to claim 1, wherein said actuating system includes:

a pressure sensor being mounted on said shoe and detecting an amount of force being exerted to said sole; and

an angle sensor being mounted on said shoe and detecting an angle of orientation of said sole.

5. The athletic footwear assembly according to claim 4, wherein said actuating system includes:

a control processor being in communication with said pressure sensor and said angle sensor;

a conductor for conducting an electric current being operationally coupled to said control processor, said conductor being operationally in communication with said magnetorheological fluid, said conductor being energized to cause said magnetorheological fluid to enter said first state and de-energized to cause said magnetorheological fluid to enter said second state, said control processor receiving data from said pressure sensor and said angle sensor and energizing said conductor on when said condition is met.

6. The athletic footwear assembly according to claim 5, wherein said conductor electrifies said magnetorheological fluid or creates a magnetic field when said conductor is energized with electricity.

7. The athletic footwear assembly according to claim 5, wherein said actuating system includes a capacitor being electrically coupled to said control processor.

8. An athletic footwear assembly configured to become rigid when a deflection event occurs to prevent injury to a person'"'"'s ankle, said assembly comprising:

a shoe including a sole and a perimeter wall being attached to and extending upwardly from said sole, said perimeter wall being configured to receive a foot, said sole having a top side, a bottom side and a perimeter edge extending between said top and bottom sides, said perimeter wall including a vamp, heel panel and an upper;

said perimeter wall including a lining comprising a foamed material, said foamed material being porous, said foamed material being resiliently compressible, said foamed material comprising a foamed elastomeric material;

a magnetorheological fluid impregnating said foamed material, said magnetorheological fluid being configured to be alternated between a first state wherein said foamed material is bendable and a second state wherein said magnetorheological fluid forms rigid columns within said foamed material such that said foamed material is not bendable, said lining forming a rigid and supportive shell when said magnetorheological fluid is in said second state, said magnetorheological fluid being arranged in a pattern within said foamed material;

an actuating system being mounted on said shoe and being in operational communication with said magnetorheological fluid, said actuating system altering said magnetorheological fluid from said first state to said second state when a condition has been met, said actuating system altering said magnetorheological fluid from said second state to said first state when a deactivation event occurs, said condition being met when said actuating system detects a combination of a threshold angle and a threshold pressure having been surpassed by said sole, said actuating system including;

a pressure sensor being mounted on said shoe and detecting an amount of force being exerted to said sole;

an angle sensor being mounted on said shoe and detecting an angle of orientation of said sole;

a control processor being in communication with said pressure sensor and said angle sensor;

a conductor for conducting an electric current being operationally coupled to said control processor, said conductor being in communication with said magnetorheological fluid, said conductor being energized to cause said magnetorheological fluid to enter said first state and de-energized to cause said magnetorheological fluid to enter said second state, said conductor electrifying said magnetorheological fluid or creating a magnetic field when said conductor is energized with electricity;

said control processor receiving data from said pressure sensor and said angle sensor and energizing said conductor on when said condition is met; and

a power source being electrically coupled to said control processor and said conductor.
