Description

Heel structure of the insole

This invention is a heel structure for an insole, which includes a cushioning element in the heel area of the insole. The cushioning element includes a flexible pad for the heel to step on, and a lower protrusion at the bottom of the flexible pad. An air bladder or an energy block is formed in the lower protrusion, thereby providing cushioning massage or energy to the human heel.

Given that insoles can support the entire body weight and absorb the impact from the ground during walking, reducing the stress on the lower limb joints and spine, increasing walking comfort and stability, and relieving foot pressure, the creator has made improvements to arch support insoles, including M669027 and M651432. After practical implementation, these arch support insoles have indeed effectively achieved the above-mentioned effects.

Based on continuous research and development to improve product functionality and reliability, the creator of this product conducted a detailed scientific study of the human foot and discovered that the intersection of the midline of the heel area and the line connecting the inner and outer ankles is the "Hundred-Tap Point" in traditional Chinese medicine meridian theory, also known as the "Insomnia Point." According to traditional medical records, frequent massage or stimulation of this point can effectively treat insomnia, relieve fatigue, and promote blood circulation. This location corresponds to the center of the heel area of the insole.

In other words, if the insole can provide a massage or slight stimulation effect in this area when the user walks, it will have the effects of treating insomnia, relieving fatigue, and promoting blood circulation as described in medical books. In view of this, the creator has accumulated many years of research and practical experience in related fields to create a heel structure for the insole, making the insole even more perfect.

Specifically, the purpose of this invention is to provide a heel structure for an insole, the insole having a plate-like body that corresponds to the shape of the human foot sole, having a forefoot area, a heel area, and an arch support area between the forefoot area and the heel area, characterized by: The top surface of the heel area has a groove in the center, and a cushioning element covers the groove. The cushioning element includes a flexible pad with an area larger than the groove for the human heel to contact and step on, and a lower protrusion at the bottom of the flexible pad. The outer contour of the lower protrusion is roughly the same as the groove so as to be embedded and fixed in the groove. The lower protrusion has a hollow cavity, which forms an air bladder or inserts an energy block to cushion or provide energy to the human heel.

With the above structure, in the heel structure of this insole, the cushioning component is embedded in the center of the heel area of the insole body. When the insole is placed inside the shoe, the flexible pad on the top surface of the cushioning component can contact the human heel to provide elastic cushioning when walking. The lower protrusion at the bottom of the flexible pad and the hollow cavity of the lower protrusion can form an airbag corresponding to the Baichao acupoint in the center of the heel to increase the cushioning and massage effect. Alternatively, an energy block can be placed in the cavity to stimulate the acupoint, so that the energy block or airbag can treat insomnia, relieve fatigue, and promote blood circulation through the Baichao acupoint on the human heel.

The implementation methods of each component are further explained below:

In practice, the outer contour shape of the flexible pad and the lower protrusion includes, but is not limited to, a circle, an ellipse, a polygon, or a horseshoe shape.

In practice, the energy block may be composed of, but is not limited to, one or more of the following materials: terahertz, magnet, jade, bamboo charcoal block, ceramic, or composite material containing graphene.

In practice, the insole is either an arch support insole with its front edge extending to the arch of the foot, or a full-foot insole with its front edge extending to the toes.

In practice, the heel area of the insole body is provided with a heel cushioning pad made of a different material from the insole body, and the groove and cushioning element are located in the center of the top surface of the heel cushioning pad.

In practice, the heel area of the insole body has a hollow part with a contour that is roughly the same as that of the heel cushioning pad, and the heel cushioning pad is embedded and fixed in the hollow part.

In practice, the insole body has an inner convex edge on the inner periphery of the hollow part, and the outer periphery of the top surface of the heel cushioning pad has a corresponding thin upper concave edge. When the heel cushioning pad is embedded and fixed in the hollow part from bottom to top, the upper concave edge of the outer periphery of the heel cushioning pad overlaps with the bottom of the inner convex edge of the inner periphery of the hollow part, so that the top surface of the heel cushioning pad is flush with the top surface of the insole body.

In practice, the insole body and the heel cushioning pad are combined by a secondary injection molding process, so that the top surface of the heel cushioning pad is flush with the top surface of the insole body.

In practice, the forefoot area of the insole is provided with a foot cushioning pad made of a different material from the main body of the insole, and the arch support area is provided with an arch support pad made of a different material from the main body of the insole.

In practice, the foot cushioning pad and arch support pad are combined with the insole body by assembly or by secondary injection molding.

Compared to previous technologies, this invention features a cushioning component embedded in the center of the heel area of the insole. This component can provide additional cushioning, massage, and stimulation to the acupoints corresponding to the center of the heel, thereby treating insomnia, relieving fatigue, and promoting blood circulation.

Based on the technical means of this invention, the following are examples of implementation methods suitable for this invention, along with accompanying illustrations:

As shown in Figures 1 to 3, the insole of this invention has a plate-shaped body 10, which is roughly the same as the outer contour of the human foot, and has a forefoot area 11, a heel area 12, and an arch support area 13 between the forefoot area 11 and the heel area 12, corresponding to various parts of the sole of the human foot.

When the body 10 is implemented, its shape can be an arch insole with the front edge 14 extending to the foot, or the body 10 can be a full-foot insole with the front edge 14 extending to the toes. The first to third figures are examples of arch insoles.

The structural features of this creation are as follows: a groove 20 is provided in the center of the top surface of the heel area 12 of the main body 10, and a cushioning member 30 is covered above the groove 20. The cushioning member 30 includes a flexible pad 31 on the top surface with an area larger than the groove 20 for human heel contact and stepping, and a lower protrusion 32 at the bottom of the flexible pad 31.

When the lower protrusion 32 is implemented, its outer contour shape is approximately the same as that of the groove 20, so that the lower protrusion 32 can be embedded and fixed in the groove 20. The lower protrusion 32 has a hollow cavity 33 inside, which forms an airbag or contains an energy block 34 to cushion or provide energy to the human heel. The implementation of the cavity 33 forming an airbag is shown in Figure 4.

In practice, the energy block 34 includes, but is not limited to, terahertz stone, magnet, jade, bamboo charcoal block, ceramics, and composite materials containing graphene. These materials can provide vibration frequencies that are beneficial to the human body, such as magnetic fields, terahertz waves, and far-infrared rays. When used on the heel, it can stimulate the Baihe acupoints on the heel, providing massage and stimulation effects, thereby treating insomnia, relieving fatigue, and promoting blood circulation.

In practice, the outer contour shapes of the groove 20 and the flexible pad 31 and lower protrusion 32 of the buffer 30 include, but are not limited to, circles, ellipses, polygons, or horseshoes. The outer contour shapes of the groove 20 and the flexible pad 31 and lower protrusion 32 of the buffer 30 shown in Figures 1 to 3 are horseshoe-shaped, while the groove 20 shown in Figure 5 is circular. The flexible pad 31 and lower protrusion 32 are corresponding shapes, making the overall buffer 30 resemble an umbrella shape that is wider at the top and narrower at the bottom.

With the above structure, in the heel structure of this insole, the cushioning element 30 is embedded in the central groove 20 of the heel area 12 of the insole body 10. When the insole body 10 is placed inside the shoe, the flexible pad 31 on the top surface of the cushioning element 30 can contact the human heel, providing a soft and comfortable elastic cushioning function.

In addition, the lower protrusion 32 at the bottom of the flexible pad 31 and the cavity 33 of the lower protrusion 32 can form an airbag corresponding to the Baichao acupoint in the center of the heel to increase the cushioning and massage effect. If an energy block 34 is placed in the cavity 33, it can stimulate the Baichao acupoint, so that the energy block 34 or the airbag can produce the effects of treating insomnia, relieving fatigue, and promoting blood circulation.

The implementation methods of each component are further explained below:

As shown in Figure 6, in practice, the heel area 12 of the insole body 10 is provided with a heel cushioning pad 40 that is made of a different material and has different softness and elasticity than the insole body 10. The heel cushioning pad 40 can be provided with a groove 20 and a cushioning element 30 to make the human heel more comfortable when stepping on it.

In a specific implementation, a hollow portion 15 with an outline approximately the same as that of the heel cushioning pad 40 can be pre-set in the heel area 12 of the insole body 10. The heel cushioning pad 40 is embedded and fixed in the hollow portion 15. The fixing method can be to combine the insole body 10 and the heel cushioning pad 40 in a combination or a secondary injection molding method.

To ensure a more stable connection between the insole body 10 and the heel cushioning pad 40, as shown in Figures 3 to 6, the insole body 10 has an inner convex edge 16 around the inner periphery of the hollow portion 15, while the outer periphery of the top surface of the heel cushioning pad 40 has a correspondingly thin upper concave edge 41. When the heel cushioning pad 40 is embedded and fixed in the hollow portion 15 from bottom to top, the upper concave edge 41 of the outer periphery of the heel cushioning pad 40 overlaps with the bottom of the inner convex edge 16 of the inner periphery of the hollow portion 15, making the top surface of the heel cushioning pad 40 flush with the top surface of the insole body 10.

Similarly, the forefoot area 11 of the insole body 10 can be provided with a foot cushioning pad 50 made of a different material than the insole body 10, and the arch support area 13 is also provided with an arch support pad 60 made of a different material than the insole body 10, to increase the elasticity and support of the insole body 10 relative to the forefoot and arch of the human body.

As for the fixing method of the insole cushioning 50 and the arch support pad 60, just like the heel cushioning pad 40, the insole body 10 can be stably combined with the insole cushioning 50 and the arch support pad 60 by assembly or secondary injection molding.

In addition, the shape of the insole body 10 shown in Figures 1 to 6 above is an arch insole with the front edge 14 extending to the arch of the foot. In this embodiment, the shape of the body 10 can also be a full-foot type insole as shown in Figure 7, that is, the front edge 14 of the body 10 extends to the toes and toes of the human foot.
