Abstract

An apparatus for foot exercise for strengthening at least the ankle and muscles around the ankle. The apparatus includes a housing having a cutout in a top wall thereof for allowing a foot of a user to pass through. A sleeve of a socks shape, hangs from the cutout, and the sleeve can receive at least the foot up to the ankle of the user. Multiple inflatable bags are disposed within the housing and around the sleeve, such that the inflatable bags, when inflated, resist movement of the foot received within the sleeve. The user can insert the foot into the sleeve; upon inserting the foot, inflates the plurality of inflatable bags; and upon inflating, moves the foot against the resistance offered by the inflated plurality of inflatable bags.

Claims (37)

1. An apparatus for foot exercise, the apparatus consists essentially of:

a housing having a bottom wall, a top wall, and sidewalls;

a cutout in the top wall of the housing, the cutout configured to allow a foot of a user to pass through;

a sleeve having a sock-like profile, wherein the sleeve has an opening for receiving the foot of the user, wherein the sleeve is configured to receive at least the foot up to an ankle of the user, wherein a periphery of the opening of the sleeve is coupled to a periphery of the cutout in the top wall, wherein the sleeve hangs within the housing;

a plurality of inflatable bags disposed within the housing and around the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to resist movement of the foot received within the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to allow movement of the foot with some counterforce;

an inflation member configured to inflate the plurality of inflatable bags;

a control unit and sensors operably coupled to the inflation member to control an amount of inflation of the plurality of inflatable bags; and

control buttons operably coupled to the control unit.

2. The apparatus of claim 1 , wherein the plurality of inflatable bags are configured to resist movement of the foot in left, right, front, rear, top, and bottom directions.

3. The apparatus of claim 1 , wherein each inflatable bag of the plurality of inflatable bags is configured to be independently filled with air.

4. The apparatus of claim 3 , wherein pressure exerted by each inflatable bag can be controlled.

5. A method for foot exercise, the method comprises:

providing an apparatus, the apparatus consists essentially of:

a housing having a bottom wall, a top wall, and sidewalls,

a cutout in the top wall of the housing, the cutout configured to allow a foot of a user to pass through,

a sleeve having a sock-like profile, wherein the sleeve has an opening for receiving the foot of the user, wherein the sleeve is configured to receive at least the foot up to an ankle of the user, wherein a periphery of the opening of the sleeve is coupled to a periphery of the cutout in the top wall, wherein the sleeve hangs within the housing,

a plurality of inflatable bags disposed within the housing and around the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to resist movement of the foot received within the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to allow movement of the foot with some force,

an inflation member configured to inflate the plurality of inflatable bags,

a control unit and sensors operably coupled to the inflation member to control an amount of inflation of the plurality of inflatable bags, and

control buttons operably coupled to the control unit;

inserting the foot into the sleeve;

upon inserting the foot, inflating the plurality of inflatable bags; and

upon inflating, moving the foot against resistance offered by the inflated plurality of inflatable bags.

6. The method of claim 5 , wherein the plurality of inflatable bags are configured to resist movement of the foot in left, right, front, rear, top, and bottom directions.

7. The method of claim 5 , wherein each inflatable bag of the plurality of inflatable bags is configured to be independently filled with air.

8. The method of claim 7 , wherein pressure exerted by each inflatable bag can be controlled, wherein the resistance offered to movement of the foot in a left direction is more than the resistance to movement in a right direction.

9. An apparatus for foot exercise, the apparatus comprises:

a housing having a bottom wall, a top wall, and sidewalls;

a cutout in the top wall of the housing, the cutout configured to allow a foot of a user to pass through;

a sleeve having a sock-like profile, wherein the sleeve has an opening for receiving the foot of the user, wherein the sleeve is configured to receive at least the foot up to an ankle of the user, wherein a periphery of the opening of the sleeve is coupled to a periphery of the cutout in the top wall, wherein the sleeve hangs within the housing; and

a plurality of inflatable bags disposed within the housing and around the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to resist movement of the foot received within the sleeve, wherein the plurality of inflatable bags, when inflated, are configured to allow movement of the foot with some force.

10. The apparatus of claim 9 , wherein the apparatus further comprises:

an inflation member configured to inflate the plurality of inflatable bags.

11. The apparatus of claim 10 , wherein the apparatus further comprises:

a control unit operably coupled to the inflation member to control an amount of inflation of the plurality of inflatable bags.

12. The apparatus of claim 9 , wherein each inflatable bag of the plurality of inflatable bags is configured to be independently filled with air.

13. The apparatus of claim 12 , wherein pressure exerted by each inflatable bag can be controlled.
