- actuator 110 may be removable from insole 150, for example via a snap fit, press fit, and/or the like.
- actuator 1 10 has an outer shape at least partially defined by a case 1 1 1.
- Case 1 1 1 may comprise multiple portions, for example upper case 11 1-A and lower case 1 1 1-B.
- Case 1 11 be formed of metal, plastic, composite, or other suitable durable material. Case 11 1 is configured to enclose various portions of actuator 110.
- pressure pad 1 12 comprises a rigid or semi-rigid structure configured to press against a person's foot.
- pressure pad 1 12 is extendable and retractable.
- pressure pad 112 may be rigid, semi-rigid, non-deformable, and/or non-bendable. Additionally, pressure pad may at least partially deformable and/or flexible, for example in order to at least partially conform to the dimensions of a portion of a human body.
- Pressure pad 112 may be made of any suitable materials, for example metal, plastic, composite, and/or the like. In an exemplary embodiment, pressure pad 112 comprises nylon 6-6. Moreover, pressure pad 112 may be comprised of any material suitable for transferring force to a person's foot. Pressure pad 112 may also be monolithic. Alternatively, pressure pad 1 12 may comprise two or more individual components.
- Pressure pad 1 12 may be at least partially pivotable, for example via disposition about center axle 1 15. In this manner, pressure pad 112 may more closely conform to a portion of a human body, for example a foot surface disposed at an angle relative to a fully retracted position or fully extended position of pressure pad 1 12.
- Pressure pad 112 can be any size to transfer a desired amount of force to a person's foot. According to an exemplary embodiment, pressure pad 1 12 applies force directly to the arch region of the foot. In various exemplary embodiments, pressure pad 112 comprises a contact surface area in the range of about 6 square centimeters to about 30 square centimeters. In various exemplary embodiments, pressure pad 112 comprises a contact surface area in the range of about 10 square centimeters to about 24 square centimeters. In other exemplary embodiments, pressure pad 112 comprises a contact surface area in the range of about 18 square centimeters to about 23 square centimeters. However, pressure pad 112 may be configured with any appropriate dimensions, surfaces, angles, and/or components, as desired, in order to transfer force to a foot.
- pressure pad 112 is configured with and/or coupled to a diffusion cap.
- the diffusion cap may be configured with dimensions approximating those of pressure pad 1 12 and/or slightly larger than pressure pad 112.
- the diffusion pad may comprise a suitable soft durable material, for example low density polyethylene plastic, elastomeric polyurethane, or foam having a thickness of between about 0.5 mm to about 1.25 mm.
- the diffusion cap may be attached to pressure pad 112, for example by adhesive, or may be molded directly onto or with pressure pad 1 12.
- the diffusion pad provides a softer element that pads pressure pad 1 12 from the foot; additionally, the extension of the diffusion pad around the edges of pressure pad 1 12 feathers the pressure of the edge to increase user comfort.
- pressure pad 112 is coupled to a-frame 1 16. Moreover, pressure pad 112 may be configured to be moved by and/or coupled to any suitable power transfer components.
- Center axle 1 15 may comprise stainless steel or other suitable axle material as is known in the art.
- Center axle 115 forms a pivotable j oint located at the peak of the "A" in a-frame 116.
- actuator 1 10 comprises a-frame 1 16.
- A-frame 116 may comprise two portions, for example a-frame 116-A and 116-B.
- A-frame 116-A and 1 16-B are at least partially pivotable about center axle 115, enabling a-frame 116 to "open” and "close”.
- center axle 1 15 (and thus, pressure pad 1 12) is extended away from the portion of actuator 110 defined by case 11 1, and as a-frame 1 16 is opened, center axle 1 15 is retracted toward the portion of actuator 1 10 defined by case 11 1.
- Torsion spring 114 is disposed about center axle 1 15. Torsion spring 114 is configured to impart a "closing" force to a-frame 116. Stated another way, torsion spring 114 is configured to impart an extension force to pressure pad 112. In certain exemplary embodiments, torsion spring 1 14 may be utilized alone in actuator 110; in other exemplary embodiments, torsion spring 1 14 may be utilized in connection with extension springs 1 18 to at least partially close a-frame 116.
- torsion spring 1 14 comprises piano wire.
- torsion spring 1 14 may comprise any suitable spring material as is known in the art.
- Torsion spring 1 14 may be configured with a suitable diameter and/or number of turns to exert a desired force on a-frame 1 16.
- torsion spring 1 14 is configured with a wire diameter of between about .05" and about .08", and preferably about
- torsion spring 114 is configured with between about 4 coils and about 7 coils, and preferable about 5.325 coils.
- extension springs 1 18, for example extension springs 1 18-A and 118-B are coupled to extension spring pins disposed in the ends of a-frame 1 16. Accordingly, extension springs 118 are configured to impart a "closing" force to a-frame 1 16. Stated another way, extension springs 118 are configured to impart an extension force to pressure pad 1 12. When a-frame 116 is opened, energy is stored in extension springs 1 18. When a-frame 1 14 is closed, extension springs 118 release energy.
- extension springs 118 comprise piano wire. However, extension springs 118 may comprise any suitable spring material as is known in the art. Extension springs 1 18 may be configured with a suitable length, diameter, spring rate, initial tension, and/or the like to exert a desired force on a-frame 116. In various exemplary embodiments, extension springs 118 are configured with an outer diameter of between about 0.15" and about 0.2", and preferably about 0.188". In various exemplary embodiments, extension springs 118 are configured with a length of between about 0.5" and about 0.6", and preferably about 0.56". In various exemplary embodiments, extension springs 1 18 are configured with a spring rate of between about 2 pounds per inch and about 4 pounds per inch, and preferably about 2.9 pounds per inch. In various exemplary embodiments, extension springs 118 are configured with an initial tension of between about 0.1 pound and about 0.3 pounds, and preferably about 0.2 pounds.
- actuator 110 torsion spring 114 and extension springs 1 18 provide stored energy for extension of pressure pad 1 12. Stated another way, actuator 110 may be considered to be "spring loaded” for extension.
- motor 124 applies a force for retraction of pressure pad 1 12. In various exemplary embodiments, force from motor 124 is applied to retract pressure pad 1 12 through lead nuts 120.
- a-frame 1 16, torsion spring 114, and extension springs 1 18 work in a complementary manner to provide a generally consistent extension force to pressure pad 1 12 as pressure pad 112 is extended, for example any suitable distance from about 0 mm to about 15 mm.
- pressure pad 1 12 may impinge on a foot at a variety of extension heights; accordingly, in insole compression system 100 pressure pad 1 12 is desirably extended with a generally consistent force, for example in order to achieve efficient blood pumping action.
- insole compression system 100 is configured to extend pressure pad 112 with a generally constant force of between about 50 Newtons and about 80 Newtons. This may be achieved via a balancing of the geometry of a-frame 116 and spring forces. For example, as a-frame 1 16 moves from an open position to a closed position, the bases of a-frame 116 react, for example against case 11 1, to push center axle 1 15 upward. As a-frame 116 closes, the reactive leverage changes; when a-frame 1 16 is open, the reactive leverage is much lower and more force is needed in order to lift center axle 115, while when a-frame 116 is closed to the midpoint and beyond, the reactive leverage greatly increases.
- torsion spring 1 14 and extension springs 1 18 are stretched into the open position for a-frame 1 16, torsion spring 1 14 and extension springs 1 18 apply a greater closing force than when they approach their relaxed positions as a-frame 1 16 is closed.
- the variable reactive leverage of a-frame 1 16 and the variable spring forces interact in a complementary way to provide an extension force for pressure pad 1 12 that is generally constant over the range of motion of pressure pad 1 12.
- insole compression system 100 is configured with a constant or approximately constant extension force. It can be seen that force from extension springs 118 and force from torsion spring 114 vary inversely from one another as pressure pad 1 12 is extended; however, the net force exerted by insole compression system 1 10 remains approximately constant.
- lead nuts 120 for example lead nuts 120-A and 120-B, are threaded about lead screw 122.
- Lead nuts 120 are disposed "inside" of a-frame 1 16 (i.e., the respective ends of a-frame 116 are located between lead nuts 120 and the outside of case 11 1).
- Lead nuts 120 may comprise any suitable durable material, for example metal, nylon 6-6 impregnated with fiberglass, and/or the like. Lead nuts 120 are configured to transfer a force generated by motor 126 to cause pressure pad 1 12 to retract.
- Lead nuts 120 may abut a-frame 1 16 but are not coupled thereto. Stated another way, responsive to rotation of lead screw 122 in a first direction, lead nuts 120 may push "outward" on lower portions of a-frame 116 to force a-frame 1 16 toward a fully opened position. However, if lead screw 122 is rotated in a second, opposite direction, lead nuts 120 do not pull a-frame 1 16 "inward" toward a fully closed position; rather, a-frame 116 is closed via application of forces from torsion spring 114 and/or extension springs 1 18. In this manner, certain components in actuator 1 10 are protected from excessive external forces exerted on pressure pad 1 12, for example a force applied by a user standing.
- a-frame 1 16 Responsive to the applied external force, a-frame 1 16 simply opens at least partially or fully (depending on the strength of the force) toward the fully open position, thus retracting pressure pad 112. Because a-frame 1 16 may be considered to "float" with respect to lead screws 122 in one direction, motor 126 and gearbox 124 are protected from damage, and a clutch or other disengagement elements are unnecessary for inclusion in actuator 1 10. Moreover, a user of insole compression system 100 is likewise protected from injury, as the force applied to the foot cannot exceed the force generated by torsion spring 114, extension springs 1 18, and a- frame 116.
- Lead screw 122 transfers force from gearbox 124 to lead nuts 120.
- Lead screw 122 may comprise any suitable durable material, for example high grade stainless steel.
- lead screw 122 may be configured with a 4 mm outer diameter having three thread starts in a 3 mm pitch.
- any suitable diameter, number of threads, and thread pitch may be utilized.
- Lead screw 122 may be configured with a right hand thread on one portion, and a left hand thread on the other portion, in order to move lead nuts 120 inward or outward simultaneously as lead screw 122 is turned in either direction.
- Gearbox 124 couples motor 126 and lead screw 122.
- Gearbox 124 comprises a mechanism configured to increase the mechanical advantage obtained by motor 126, for example a reduction gearbox. Output force from motor 126 is transferred through gearbox 124 in order to achieve an appropriate gear ratio for effectuating movement of pressure pad 112.
- gearbox 124 may have a fixed gear ratio.

Stated another way, insole compression system 100 is configured to facilitate "athletic recovery," or the augmentation of blood flow in the body's venous system to deliver nutrients to the muscles while simultaneously removing lactic acid and metabolic waste. After a workout, it has been found that a person may recover more quickly from the after-effects of exercise (for example, accumulation of lactates in the muscle and/or blood) via low-intensity physical exertion rather than via complete rest.
- the increased blood circulation attendant to low-intensity physical exertion facilitates the removal of cellular metabolic waste and lactic acid from muscle and the reduction of lactate levels in the bloodstream. Additionally, physical exertion can facilitate facilitating opening the capillary bed to enable remedial hydration and/or efficient nutrient transfer. In contrast, post-workout periods of immobility, for example either sitting or recumbent, do little physiologically to promote athletic recovery. Lowered venous peak velocity and reduced circulation closes the capillaries and locks lactic acid in place, which influences swelling and muscle soreness.

Insole compression system 100 may be utilized after a workout for a suitable duration, for example a duration of between about 10 minutes to about 2 hours, in order to assist in athletic recovery. While residual cellular metabolic waste can take several days to flush from the soft tissues, this process can be greatly accelerated via use of insole compression system 100 after a workout. To facilitate use of insole compression system 100 as part of an athletic recovery program, insole compression system 100 may be inserted into athletic footwear intended for use during a workout. Moreover, insole compression system 100 may also be inserted into post-exercise footwear.
- Insole compression system 100 may be utilized on a regular schedule by a person, for example as part of a pre-workout warmup, a post-workout cooldown, and/or on days when no workout is scheduled.
