Description

Dynamic double arch support pad

The present invention provides a dynamic double arch support pad, especially a kind of arch pad that is used alone and placed on the bottom side of the space in the shoe, or the arch pad is embedded in the insole as a functional protective product , the longitudinal and transverse arch pads distributed on the surface of the contact layer of the arch pad effectively support the arch of the foot, and the arch pad forms a three-layer structure of the hardest, second-hardest and softest from top to bottom , in order to achieve the pressure relief function of users in various states when standing, walking or running, and to achieve the optimal protection function for the arch of the foot.

Press, the foot bears the weight of the whole body. When walking, running, jumping and bearing weight, the arch on the bottom side of the sole of the foot must not only support our body, but also provide pressure bearing, pressure cushioning, pressure release, shock absorption and stability. Functions such as gait and walking propulsion. The origin of the name of the arch of the foot is that the arch of the foot is like a bow, which has the function of elastic stretching and can effectively absorb the ground reaction force returned from the ground. It is deformed by stress to withstand strong impact, so as to maintain the balance and stability of the body when landing.

Furthermore, the purpose of the arch structure of the human foot is not only for simple cushioning, but also for energy storage and balance and stability in daily life. There are three arches that control the soles of our feet: the inner longitudinal arch, the outer longitudinal arch, and the transverse arch, which are responsible for absorbing the ground reaction force generated during the body's progress. If these three arch structures are poor, the efficiency of our walking will be greatly weakened, and the weight will be heavy. The heart cannot be transferred to the correct positions smoothly, and the body is prone to imbalance. When the arch of the foot is too low, it will cause the foot to rotate inward, which will cause the tibia, femur and hip joint to rotate inward, forming a knee valgus state (Knee Valgus) and making the ipsilateral pelvis tilt downward. At this time, the spine for Maintaining the posture will tilt to the opposite side, which will cause the other shoulder to sag (on the same side as the pelvis). In recent years, jogging has become popular, because running is relatively easy for the general public to get started, and there are no environmental restrictions. However, the seemingly simple jogging exercise is actually closely related to the posture of the human body. After running for a period of time, the footsteps gradually become tired, and the posture of the feet landing will gradually change. If the original foot arrangement is not in the normal state or if the foot fatigue occurs after long-term running, and the muscle strength cannot bear the load, it will Make the foot rotate inward, in this state, it will increase the incidence of sports injuries.

To reduce the occurrence of the above situations, first of all, avoid sudden increase in the amount of exercise, and control the exercise intensity within a moderate range according to each person's physical ability, and abide by the principle of increasing the amount of exercise step by step. Therefore, how to use external force assistance such as insoles and protective gear (foot arch decompression pads) to achieve the purpose of protecting the user's arch has become the goal of the relevant researchers.

Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, and after various evaluations and considerations, the invention of this dynamic double arch support pad was designed.

The main purpose of the present invention is to provide a dynamic double arch support pad, which includes a contact layer that is located at the top and fits with the concave arch on the sole side of the sole and has the highest hardness. The surface of the contact layer is raised with a larger volume. A longitudinal arch cushion block and a transverse arch cushion block with a smaller volume, and a base plate with the lowest hardness is provided on the bottom surface of the contact layer, a plurality of protrusions are arranged on the surface of the base plate, and the recesses between these protrusions are provided with A plurality of pressure relief grooves in a staggered shape, and a plurality of intersecting areas are formed at the intersection of these pressure relief grooves, and a connection layer with the next highest hardness is provided between the contact layer and the bottom plate, On the bottom side of the sole of the foot, there is a pressure center of gravity trajectory line with a pressure center of gravity offset according to different motion states, and the protrusions on both sides of the intersection area under the pressure center of gravity trajectory line are expanded outwards to relieve the pressure Downward stress due to center of gravity trajectory. With the above-mentioned structure, whether it is to use alone the arch pad placed on the bottom side of the space in the shoe, or to embed the arch pad in the insole as a functional protective product, through the contact layer of the arch pad The longitudinal arch pads and transverse arch pads distributed on the surface effectively support the arch of the foot, and the arch pads form the hardest, second-hardest and softest three-layer structure from top to bottom, so as to achieve the user's standing, It can relieve pressure in various states when walking or running, and achieve the optimal protection function for the arch of the foot.

The secondary purpose of the present invention is that the arch pad includes a chestnut-shaped horizontal arch pad from top to bottom, and a connecting area that is approximately trapezoidal in appearance and not raised obliquely extends below the horizontal arch pad. The longitudinal arch spacer with a tapered shape and the tip pointing down obliquely extends below the connection area.

Another object of the present invention is that the arch support is embedded in an insole to form an integrated structure. The insole is formed with an outer edge corresponding to the base of the little toe of the sole of the foot and an inner edge is formed corresponding to the base of the big toe of the sole of the foot. The tangent line from the outer edge to the inner edge has an angle of about 15 degrees with the horizontal line extending from the outer edge, and the tangent line from the outer edge to the inner edge is obliquely cut at the transverse arch pad Above the block, and the horizontal line extending from the outer edge passes through the center of the transverse arch pad block, and divide the two-dimensional coordinate ratio of the X and Y axes according to the position where the insole faces upward and the outer edge faces inward, and the insole The outer edge is the 0% reference value of the X-axis and the heel of the shoe is the 0% reference value of the Y-axis. The coordinate ratio of the upper end point of the longitudinal arch pad near the inner edge is (95%, 60%); the coordinate ratio value of the lower end point of the longitudinal arch pad near the inner edge is (95%, 28%); the coordinate ratio value of the upper end point 37 of the longitudinal arch pad block near the center of the sole is (66 %, 53%). .

Another object of the present invention is that the trajectory of the pressure center of gravity refers to the Extend forward to the junction of the outer longitudinal arch area and the inner longitudinal arch area of the sole of the foot, to the center of the transverse arch area of the sole of the foot, and between the big toe and the index toe of the toes.
