Description

A sole that introduces a biodynamic point of view of the foot pressure center trajectory

This creation is about shoes, in particular a sole that introduces a biodynamic perspective on the trajectory of the center of foot pressure.

Studies have pointed out that the moving track of the center of plantar pressure (COP) is approximately on the outside of the midline of the plantar, and the offset COP track is likely to cause abnormal moments generated by the ground reaction force on the ankle joint and knee joint.

According to the foot pressure curve, walking usually uses the space between the first and second toes as the propulsion force point. Therefore, the use of rebound materials on the parts opposite to the first and second toe bones conforms to gait biomechanics and effectively achieves labor-saving propulsion Effect. That is to say, when a person walks, the heel will first receive the ground pressure, and then move from the fifth metatarsal head to the first metatarsal head on the outside of the foot, and then step forward to start walking. Based on the above gait biomechanics, it is necessary to strengthen the support capacity at the appropriate position and guide the movement trajectory of the walking foot pressure center.

Applicant No. M572669 "Sole with Comfortable Kinetic Energy Structure" provides the sole support area, midfoot support area and heel support area completely based on foot scan analysis, which conforms to the arrangement of foot bones and naturally fits the curvature design of the foot , shock absorption, decompression, elasticity, comfort, reduce the reaction force of contact with the ground, coordinate walking movements, guide the moving track of the walking foot pressure center, and achieve the purpose of labor saving and comfort.

The main purpose of this creation is to introduce the sole support pad into the biodynamic point of view of the center track of foot pressure, support most of the sole of the foot including the forefoot metatarsal, midfoot and rear heel bone with a rigid pad with good coverage; support with an elastic pad Relative to the narrow and long section of the first and second phalanges, the support effect constructed by the two can effectively prevent the excessive deviation of the center of gravity (COG) of the foot, so as to reduce the abnormal moment generated by the ground reaction force on the ankle joint and knee joint, and Improves the effort-saving propulsion effect of the first and second phalanges.

In order to achieve the above purpose, the sole of this creation is composed of rubber outsole, EVA midsole and support pad from bottom to top. Among them, the rubber outsole is attached to the bottom surface of the EVA midsole, and the front of the EVA midsole is reserved There are grooves corresponding to the shape of the support pad, so that the support pad can be placed on the front of the EVA midsole.

In one embodiment of the present creation, the support pad is integrally formed of nylon material and includes a rigid pad and an elastic pad. block, while the elastic pad supports the narrow section opposite the first and second phalanges.

In one embodiment of the invention, the rigid pad wraps the inner and outer arches and heels, that is, forms a valgus curvature at the inner and outer arches, and extends the curvature backwards to the heel to form a The cup-shaped, structured support effect can effectively prevent the excessive shift of the center of gravity of the sole of the foot, and reduce the abnormal torque generated by the ground reaction force on the ankle joint and knee joint.

In one embodiment of the invention, the elastic pad extends from the front edge of the rigid pad toward the first and second phalanges into a flat sword-shaped protrusion, and a plurality of serrations are cut on the sword-shaped protrusion Shaped notch, with flexible elasticity to improve the effort-saving propulsion effect of the first and second phalanges.

Please refer to Fig. 1 to Fig. 3, the sole of this creation is composed of wear-resistant rubber outsole 1, elastic EVA midsole 2 and nylon support pad 3 from bottom to top, wherein rubber outsole 1 is attached to The bottom surface 21 of the EVA midsole 2, and the front footbed 22 of the EVA midsole 2 are reserved with a groove 221 corresponding to the shape of the nylon support pad 3, so that the nylon support pad 3 can fit 2 and be positioned on the front shoe of the EVA midsole. Bed 22; the nylon support pad 3 is integrally formed by nylon material and includes a rigid pad body 31 and an elastic pad body 32. The rigid pad body 31 supports most of the soles of the feet, that is, the front foot metatarsal bone, the middle foot to the rear heel bone block, while the elastic cushion body 32 supports the narrow and long section opposite to the first and second phalanges. Wherein: the rigid pad body 31 covers the inner and outer arches 311, 312 and the heel 313, that is, the inner and outer arches 311, 312 form valgus curvature, and extend the curvature backward to the heel position and form The support effect of the cup shape can effectively prevent the excessive deviation of the center of gravity of the sole of the foot, and reduce the abnormal moment generated by the ground reaction force on the ankle joint and knee joint; because the first and second phalanges have a propulsive role in gait biomechanics ,if Using a rigid support material will cause difficulty in advancing the phalanx, so the support material at this position must be elastic. Therefore, the elastic pad 32 of this invention extends from the front edge of the rigid pad 31 toward the first and second phalanges into a flat sword shape. protrude, and cut out a plurality of jagged slots 321 on the sword-shaped protrusion, so as to improve the effort-saving propulsion effect of the first and second phalanges with flexible elasticity.
