Description

Heel shock absorber

The present invention relates to a device for adjusting the force of the human heel to facilitate standing or walking for a long time, and particularly to a heel shock absorber that is cushioned on the sole of the foot to reduce heel pressure.

With the development and progress of the economy, the opportunities for physical labor in modern life are greatly reduced compared to the past, which in turn leads to insufficient exercise for modern people and causes civilization diseases such as dysmetabolic syndrome, obesity, high blood pressure, hyperlipidemia, and poor cardiopulmonary function. Increasing unabated. In addition to these diseases of civilization, there is a common and common chronic pain. The main reason for this kind of chronic pain is that bad movements and postures make the skeletal muscles lose balance. In terms of biological evolution, in the course of human evolution, human beings evolved from crawling on four legs to walking upright on two legs. In order to maintain the balance in the state of standing upright with two legs and walking upright with two legs, the skeletal muscles will reconcile each other to replace the compensation function, so that the human body does not fall when standing upright with two legs, while walking upright with two legs Can continue to travel in the state.

However, the aforementioned replacement of compensation is a kind of interaction between different skeletal muscles. This interaction between skeletal muscles may cause various bad actions and postures when standing or walking, and bad actions and postures. It also makes the skeletal muscles lose their balance, which leads to bad movements and postures. Instead of compensation, it causes the aforementioned chronic pain and various aches.

Since the aforementioned chronic pain and various sorenesses come from the human body's overall replacement and compensation effect, it is difficult for medical technology or science and technology in related fields to easily prescribe the right medicine or solve the problem in a targeted manner, that is, the existing medical technology or science and technology are not yet available. Provide concrete and simple and feasible means to maintain the body's bones, muscles and joints in a balanced state at any time in daily life, and there is no way to effectively avoid the pain and the aforementioned chronic pain caused by bad movements and postures.

When humans are standing or walking, the ideal state is to let the sole of the foot correspond to the position of the first metatarsal, the position of the sole of the foot to the fourth metatarsal, and the position of the sole of the foot to the heel form a three-point support state, so that the skeletal muscles The system naturally maintains a neutral and balanced position when standing or walking.

The above-mentioned three-point support state is an ideal way for humans to contact the ground when standing and walking. Under natural conditions, the soles of the feet and the soles are easier to form a three-point support state. However, the contact surface between the heel position of the foot and the shoe is oval and curved, which interferes with the position around the heel of the foot. The main problem is that this interference will make the heel and the sole contact improperly, which will make the body weight imbalance, and make the specific position of the foot have to bear greater pressure. This will not be conducive to the balance of the body, and also change the way of standing or walking and cause bad movements and postures.

In response to the above problems, the improvement methods of doctors who dealt with foot problems or related manufacturers such as the shoe industry include adding posts to the structure of shoes and digging holes in the structure of shoes corresponding to the heel. Soft and elastic material, or the shape of the heel cup, etc. However, the aforementioned existing improvement methods have instead caused the interference and increased force on the heel to achieve the improvement. Good purpose. The reason is that the aforementioned method of using a tapered object or a soft material or a heel cup can change the state of the bad action posture caused by the inadequate contact between the heel and the sole, but it cannot effectively reduce the pressure on the heel.

The configuration of body weight usually requires a variety of methods to effectively solve it. For example, the use of large-angle shoes to avoid heel valgus, or the use of obliquely angled uppers to facilitate the application of force on the inside of the soles, which is beneficial for standing or walking and can reduce interference. In addition, insoles can be used to achieve an even foot contact force The purpose of distribution. Although the above-mentioned three improvement methods such as adopting a large-angle shoe shape, an oblique angle upper or adopting an insole have their effects, none of the aforementioned three existing structures can completely eliminate the heel interference, so that the strength of standing or walking is fed back. The body causes a bad substitute compensation effect. That is, even if the existing structure is adopted, it is still impossible to manufacture shoes that can eliminate excessive heel stress and allow the user to stand or walk in an ideal state.

The market has a demand for heel shock absorbers that can reduce the interference on the heel, but there is currently no product on the market that can meet this demand. Therefore, how to provide products that can meet this demand is an urgent problem to be solved.

In view of the inability of the aforementioned existing technologies to effectively solve the problem of heel interference and the market demand for related products, the main purpose of the present invention is to provide a heel shock absorber that reduces the pressure on the heel and reduces heel interference .

In order to achieve the above-mentioned object of the invention, the main technical means adopted by the present invention is to make the aforementioned heel shock absorber include a body, a heel portion provided on the aforementioned body, and an oval support portion located on the aforementioned heel, The elliptical support part is inclined to the four directions to form an inclined peripheral edge of the heel, and this The body is gradually decreasing at the inclined peripheral edge of the heel, and the body can also be reversed, which also has the same effect.

Because the present invention has the above-mentioned structure, no matter the height difference is formed into an inclined plane, arc surface or flat shape, in general, the aforementioned height difference changes the contact force between the human foot and the cushion body, reduces the pressure on the human heel, and makes The heel is less susceptible to interference, and the weight is more appropriately distributed on the heel, and forms a three-point support state with the sole of the foot to maintain balance, avoid bad movements or posture compensation and avoid chronic pain.

The first figure is a top view of the first embodiment of the present invention

The second figure is a cross-sectional view of the second embodiment of the present invention.

The third figure is a schematic side view of the application of the present invention to shoes.

Please refer to the first figure. The present invention is a heel shock absorber. The first embodiment of the present invention includes a body (10), a heel portion (11), an oval support portion (12), and an inclined peripheral edge portion of the heel ( 13).

The aforementioned body (10) is used to cushion the sole of the foot to bear the weight and cushion the reaction force of the ground on the foot when standing or walking. It is mainly composed of a simple design method and has a body with a heel inside. Part (11), an elliptical support part (12), a heel inclined peripheral part (13), in addition, the aforementioned body (10) can be formed as an insole, sandal sole material, slippers sole material, etc. Class appliances for users to use in daily life.

The aforementioned heel portion (11) is formed on the aforementioned body (10) for bearing the human body on the aforementioned heel portion (11), and the thickness variation of the aforementioned body (10) at the heel oblique peripheral portion (13) is Decrease to the Quartet. When the aforementioned body (10) is formed as an insole, shoe outsole, or sandals and slippers, and other footwear that is put on the foot, the aforementioned heel part (11) and heel elliptical support part ( 12) Formed on the top surface of the aforementioned body (10).

The inclined peripheral edge portion (13) of the heel is located on the heel portion (11) and around the elliptical support portion (12).

Please refer to the third figure. With the above structure, when the present invention is applied to the foot (90) of the human body, the sole of the foot is in contact with the top surface of the body (10), and the weight of the whole body is determined by the body (10). ) Bear. The heel position (91) of the sole corresponds to the elliptical groove part (12) and the inclined peripheral edge part (13) of the aforementioned heel part (11) respectively.

Please refer to the first figure again. The ideal human standing or walking state is the aforementioned three-point support state. It can be seen that in addition to the aforementioned heel, there is not only a problem of excessive pressure on the heel, but also when standing or walking. The position of the peripheral edge of the heel (13) may be due to the inversion or valgus of the ankle joint, forming a post effect. The oblique method is used to reduce the surrounding contact force and reduce the imbalance factor. In addition, the body (10) first contacts the oval shape when the heel is stepped on The support part (12) decelerates downward due to the change of the contact area, and the contact area of the inclined peripheral part (13) increases to produce a buffering effect and form a shock absorber function, which can effectively solve the problem of excessive heel pressure.

When the aforementioned inclined peripheral portion (13) reduces the pressure around the heel, it can effectively prevent the overall heel from affecting the balance of the skeletal muscles due to unbalanced contact force, and further promote the maintenance of a three-point support state.

In other words, both the elliptical support portion (12) and the inclined peripheral edge portion (13) in the structure of the present invention can reduce heel pressure and allow the body to naturally maintain a balanced state.

The heel shock absorber provided by the present invention can be lowered and blended The strength of the heel can change the contact between the heel and the shoe and reduce the interference between the heel position of the foot and the position around the heel. By reducing the aforementioned interference, the musculoskeletal system is naturally maintained in a neutral and balanced position when standing or walking, achieving the most ideal state, so that the body structure can smoothly adjust the body's center of gravity, and then change the body posture to maintain balance. Using the present invention to continuously maintain the body's skeletal and muscular system in an ideal state of balance can reduce possible injuries caused by skeletal and muscle imbalance, improve people's soreness and chronic pain, and make people feel comfortable all over the body and avoid bad movements or postures. Coming hurt.
