Sole of shoes

The present invention relates to shoe soles, and more particularly, to a shoe sole that has a cushioning function and provides a comfortable fit.

Shoes protect your feet and mitigate impact from the ground when walking. Walking is the most basic of human life behaviors, and most of human movements, so shoes have a great impact on walking.

In particular, as the interest in health and the recognition of the foot as the source of health in recent years, shoes with a shock absorbing function have been introduced for shock reduction.

However, recently introduced shoes have a problem in that the cushioning function is only designed with only the effect of shock mitigation on the wearer's weight, so that energy consumption is high and fatigue is increased when walking for a long time.

An object of the present invention is to solve the above problems, to provide a shoe sole that has a cushioning function, but minimizes the fatigue of the foot even when walking for a long time in an ergonomic configuration and have a comfortable fit.

According to a feature of the present invention for achieving the object as described above, the present invention is made of an elastic body, the insole is formed in the upper surface corresponding to the arch of the foot, and disposed on the bottom of the insole, the heel in the metatarsal of the foot It includes an intermediate window provided with a support member of the leaf spring material for elastically supporting the bottom portion of the insole corresponding to.

One end of the supporting member is supported by a hook channel provided at the front end of the middle window, and the other end thereof is fixed to the rear end of the middle window by a fixing means to form a curve corresponding to the arch of the foot.

An extra space is formed in the hook channel to accommodate the longitudinal extension during elastic deformation of the support member.

The fixing means may be formed in a ring-shaped female bracket and male bracket formed at positions corresponding to each other of the intermediate window and the rear end of the support member, and fastening holes formed in the female bracket and male bracket in a state where the female bracket and male bracket are coupled to each other. It includes a fastening bolt and a fastening nut fastened through the through hole.

A protrusion is formed on any one of a bottom surface of the support member and an upper surface of the intermediate window.

The support member is a reinforced plastic material.

Hereinafter, preferred embodiments of a shoe sole according to the present invention will be described in detail with reference to the accompanying drawings.

The shoe sole 10 of the present invention is made of an elastic body, the insole 11 is formed on the top surface corresponding to the arch of the foot, and the insole 11 is disposed on the bottom surface of the insole 11 and the rear end of the insole 11 An intermediate window 17 is provided with a support member 15 made of a leaf spring material to elastically support the portion.

Your feet are easily fatigued because they consist of only small muscles that are sensitive to fatigue. In particular, when abnormal pressure is applied to a specific part of the foot, fatigue and abnormalities appear in the calf or knee, and in severe cases, the pelvis and waist, reproductive organs, spine, shoulder, nape, and abnormalities appear.

Therefore, the present invention is to make the shoe sole 10 in contact with the sole to distribute the weight well, while minimizing the shaking during walking while also excellent wear.

Insole 11 is the part on which the foot is placed. As shown in Figures 1 and 2, the insole 11 has a curved shape of the upper surface by the ridge 13 corresponding to the arch of the foot corresponding to the curvature of the sole. Furthermore, the insole 11 is formed relatively thicker than the portion corresponding to the sole or arch of the thickness corresponding to the heel. This keeps the normal pressure on the sole of the foot at all times while walking to minimize the burden on the spine. The bottom portion of the insole 11 has a recessed shape corresponding to the shape of the support member 15.

The insole 11 uses an elastic body to increase the feeling of wearing. The elastomer serves as a cushion when weight is loaded. The elastic body may be a sponge, a memory foam, cork material and the like having a high density to maintain the normal pressure on the entire sole of the foot.

If the insole 11 is excessively fluffy, the fatigue of the muscles is aggravated by severe shaking of the entire human body when walking. In order to prevent this, a high density elastic body is employed. The material and shape of the insole 11 increases the area where the sole is in contact with the ground so that the weight is evenly distributed throughout the sole.

The midsole 17 is intended to perform a cushioning function together with the insole 11. The support member 15 is coupled to the middle window 17 to perform a cushioning function.

As shown in FIG. 2, the supporting member 15 is supported on one end of the hook channel 19 provided at the front end of the middle window, and the other end is fixed to the rear end of the middle window 17 by the fixing means 21. do. When the support member 15 is fixed to the middle window 17, the support member 15 has a curved shape that forms a gentle curve corresponding to the arch of the foot. By this shape, the rear end of the bottom face of the insole 11 is elastically supported.

2 and 5, the intermediate window 17 is substantially plate-shaped, and the hook channel 19 is formed at the tip. The hook channel 19 is formed by a stepped end portion of the middle window 17 and a rear end of the stepped tip portion recessed toward the tip side. One end of the support member 15 is supported by the hook channel 19.

2 and 3, the hook channel 19 has a clearance A for accommodating the longitudinal extension in the elastic deformation of the support member 15. The clearance A is formed by the hook channel 19 being further recessed toward the tip side. The clearance A enables the support member 15 to elastically support the bottom end of the insole 11 in the state where the weight is loaded. The free space A prevents the support member 15 from excessively pushing the pressure toward the arch while supporting the arch.

As shown in Figures 1 and 6, the fixing means 21 is a ring-shaped female bracket 23 and the male bracket 25 formed at positions corresponding to each other of the rear end of the middle window 17 and the support member 15; The female bracket 23 and the male bracket 25 include a coupling bolt 27 and a coupling nut 29 that are fastened through the female bracket 23 and the male bracket 25 in a coupled state. The reason for fixing the part corresponding to the heel with the structure of the female bracket 23 and the male bracket 25 is to minimize the shaking of the heel. Excessive heel swings tend to cause blood in the lower extremities and plantar areas.

A fastening hole 23a is formed in the female bracket 23, and a through hole 25a communicating with the fastening hole 23a of the female bracket 23 is formed in the male bracket 25. The fastening bolts 27 are fastened through the fastening holes 23a and the through holes 25a.

In the present embodiment, the middle window 17 is substantially plate-like, and has a structure in which a hook channel 19 is formed at the top end and an arm bracket 23 is provided at the rear end. In addition, the support member 15 has an arch shape having a predetermined radius of curvature in the middle thereof, and is formed flat so that both ends thereof can be coupled to the middle window 17. A portion of the support member 15 corresponding to the female bracket 23 of the middle window 17 is provided with a ring shaped male bracket 25 inserted between the female brackets 23.

The support member 15 elastically supports the bottom portion of the insole corresponding to the heel in the metatarsal bone of the foot. Support in this area protects the arch and distributes the weight and impact on the heel to minimize foot fatigue and stress when walking.

The arch of the foot has a shock-absorbing function when supporting weight or walking, and when the foot is collapsed, the foot is easily tired and it is difficult to walk for a long time. And, if severe, excessive load is transmitted to the knee and damage to the knee joint proceeds, and further progresses to weakening of the lumbar pelvis.

When the human body is standing, the weight is carried out in a 1: 1 ratio on the heel and the toe, but when walking, the weight is moved in the order of the heel, the sole, the toe. As the weight moves, the weight the foot receives due to collision, lift and propulsion increases.

Therefore, while supporting the arch, by using the elastic force of the support member (plate spring) 15 to distribute the pressure applied to the foot throughout the sole. This takes into account the precise pressure structure of the foot, which lowers energy consumption during long walks and minimizes foot fatigue.

As shown in FIG. 2, a protrusion 31 protruding toward the middle window 17 is formed at the center of the bottom of the support member 15. The protrusion 31 serves to prevent the support member 15 from being worn by mutual contact between the support member 15 and the middle window 17 when the support member 15 is extended. In the present embodiment, although the protrusions 31 are illustrated as being formed in the support member 15, the protrusions 31 may be formed in the intermediate window 17 instead of the support member 15.

The material of the support member 15 is reinforced plastic. Reinforced plastic is a plastic that has improved filler hardness, strength, tensile strength, heat resistance and impact strength by adding fillers (additives) to ordinary plastics. These reinforced plastics are lightweight, have high mechanical strength and are durable. Therefore, when used as the support member 15 of the above-described structure is excellent in supporting the arch while reducing the weight of the shoe. The midsole 17 can also be made of reinforced plastic.

On the other hand, the insole of the soft leather material is disposed on the upper surface of the insole 11 when manufacturing shoes, the sole may be further provided on the bottom surface of the middle window (17).

Hereinafter, the operation of the present invention having the configuration as described above will be described.

The shoe sole 10 constitutes the bottom portion of the shoe, and the intermediate sole 17 to which the support member 15 is coupled is disposed at the rear end of the bottom of the insole 11.

In the method of coupling the support member 15 to the middle window 17, first, the male bracket 25 of the support member 15 is positioned between the female brackets 23 of the middle window 17 in the state of FIG. 3. The fastening hole 23a of the 23 and the through hole 25a of the male bracket 25 communicate with each other. In this state, the fastening bolts 27 pass through the fastening holes 23a and the through holes 25a. The fastening nut 29 is fastened to the end of the fastening bolt 27 passing through the fastening hole 23a and the through hole 25a. (See FIG. 6)

Next, the tip of the support member 15 is inserted into the hook channel 19. The support member 15 can then act as a leaf spring.

When the support member 15 is coupled to the midsole 17, the midsole 17 to which the support member 15 is coupled is disposed at the rear end of the bottom of the insole 11. At this time, the midsole 17 to which the support member 15 is coupled is disposed at the bottom portion of the insole 11 corresponding to the heel of the metatarsal bone of the foot.

Then, when weight is applied during ignition or walking, the support member 15 serves as a leaf spring to support the arch of the foot. At this time, the support member 15 is disposed on the bottom surface of the insole 11, which serves as a cushion, and serves as a leaf spring for supporting the arch, thereby having a shock absorbing function, preventing excessive weight from being directed toward the arch and impacting the sole of the foot. Will be absorbed once more. Therefore, not only the impact dispersion during walking is maximized, but the weight is evenly distributed over the entire sole of the foot to minimize fatigue even when walking for a long time.

This does not strain the joints or the spine and helps with posture correction.

Shoe sole 10 having the above-described configuration is applicable to a variety of shoes, such as safety shoes, running shoes, jogging shoes as well as canvas shoes, golf shoes that apply a lot of force to the ankle or knee.

It is to be understood that the invention is not limited to the disclosed embodiments, but is capable of many modifications and alterations, all of which are within the scope of the appended claims. It is self-evident.
