Description

Shock Absorbing Shoes {Shock Absorbing Shoes}

When walking, depending on the speed of walking, the impact of 1.5 to 2.0 times your weight is applied to the heel of your shoes by the speed of the foot's contact with the ground, and the impact repulsive force is transmitted to the heel, which causes abnormalities in the body, especially the knee joints. Will result.

The heel of the shoe is a part that transmits an impact when walking, and in the case of sneakers, it uses a pylon or polyurethane midsole or an airbag to absorb the shock, but in the case of shoes, the shock absorption is weak. In this case, when the shock absorption is transmitted, the parts of the human body, especially the knee joints, etc. are unknowingly damaged due to this shock, and there is a problem in that walking fatigue is aggravated.

Conventional shoes have been designed and manufactured in a state in which only the appearance is important, ignoring the shoe anthropological aspects such as shock transmission and absorption during walking. In order to solve the above problems, efforts have recently been made to minimize the impact reflected on the heel by absorbing the impact of the heel of the shoe using a shock absorbing material such as a spring on the sole, but this has not been applied to the actual product production. .

According to the Republic of Korea Utility Model No. 1998-05945, a spring-loaded cushion device is installed in the heel of the shoe and a groove for air circulation in the outsole is provided to circulate the shock and circulate air inside the shoe by reciprocating movement of the cushion device during walking. Shoe is proposed, but only the cushion device is inserted in the state in which the heel midsole portion in which the cushion device is inserted is incised.

According to Republic of Korea 2000-0001646, the air circulation passage is provided on the sole of the shoe, the spring with the support plate attached to the top of the heel is installed, and the insole is placed on the support plate so that shock absorption and air inside the shoe are circulated when walking. have.

According to Korean Utility Model No. 1993-0003228, a cushion plate with a spring attached to the lower surface of the synthetic resin board and a sponge attached to the upper surface is attached to the back of the shoe insole to absorb shocks when walking.

According to Korean Utility Model No. 1982-0002645, the coil spring is attached to the bottom of the double bent elastic layer, and the coil spring part is installed in the heel of the shoe, and the double bent elastic layer is placed on the bottom of the insole to absorb shocks when walking. Suggested to.

According to Republic of Korea Patent Application No. 1990-15226, shock-absorbing shoes have been proposed to minimize the sole thickness of a shoe by inserting a spring wound inside the shoe and making the spring thin when the spring is pressed when walking.

According to Korean Laid-Open Utility No. 1999-0036897, it is proposed to insert a spring into the shoe insole to absorb shock by compression of the spring inside the insole when ignited.

According to Korean Laid-Open Utility No. 1999-014278, a spring is installed in the heel of a shoe that is divided into two upper and lower parts, and the lower part of the heel moves by the spring when the walking is moved to absorb the shock.

U.S. Patent No. 5,511,324 suggests that a spring-loaded disk is inserted into a cylindrical throughhole at the bottom of the heel and the spring-loaded disk touches the ground first to absorb shocks when walking.

If the technique is not extended to the heel of these techniques, the upper part of the heel is not fixed in the lasting process of attaching the upper to the texture using the new bone, which is the first step in the actual manufacturing process of the shoe. This is technically difficult and due to this, manufacturing defects and adhesion problems occur, and when the spring is inserted through a hole in the sole of the sole, the inner part of the shoe and the foot contact with each other are structurally blocked. There is a problem that does not feel.

Typically, shoes such as shoes are composed of soles or heels, midsoles, texions, insoles and uppers, and the soles and uppers have the function to maintain the structural form of the shoes, and the midsoles and insoles have the ability to absorb shocks when walking. have.

And the traction is essential for fixing the upper part and the midsole part in the case of sneakers, and in the case of shoes, it is essential for the fixing part of the upper part and the outsole part. Omitting the texture part in the current shoe manufacturing process results in incomplete adhesion between the upper and the midsole or the outsole, and thus causes a poor adhesion between the upper and the midsole or the outsole while wearing the shoe.

In shoes with a shock absorbing function using a conventional texture, the shock absorbing portion of the shock absorbing part is subjected to a lot of shear stress due to the change of tensile force by repeated up and down movements, and as time passes, wrinkles become weaker and the strength decreases. This results in poor adhesion.

In order to solve the problems of practical use, the present invention double-structures the forefoot shock absorbing part and the foot shock absorbing part in the elastic material, which is essential for shoe manufacturing, and the part of the texture due to the compression and extension of the shock absorbing part during walking. This increase in stress was reduced as an elastic material to solve the problem of adhesion failure caused by deformation.

In addition, the forefoot shock absorbing portion and the foot shock absorbing portion formed in the outsole for additional cushioning to support the weight of the entire foot to improve the landing feeling.

If you walk with a shoe that is shock-absorbing in a shoe sole using a shock-absorbing material such as a spring or a sponge, the foot absorbs the shock-absorbing material from the sole of the shoe as the foot touches the ground, Will enter. In the case of applying the shock absorbing function of the heel of the shoe by applying the conventional traction structure, the traction is subjected to tension as deep as the heel portion enters the inside of the sole, and thus the sheer stress is applied to the edge bonding portion by the tension applied to the tex. do. When walking, the impact force about 2.0 times of weight is applied to the traction, and the tensile force applied to the traction is repeated as many times as walking, and the shear stress applied to the adhesive part is also repeated as many times as the adhesion between upper and traction and sole Defects will occur.

In order to solve this problem, the present invention solves the adhesion defect by double-structuring the forefoot shock absorbing portion or the foot shock absorbing portion of the texture with an elastic material and protrudes the foot shock absorbing portion of the texture by 1 to 10 mm.
