Description

[0001] The present invention relates to a shock-absorbing device for shoes,

The present invention is an improvement of the "shoe shock absorber ", which was filed by the applicant of the present invention (10-2014-0111839, 2014.08.26), in which the shock absorber is separated and replaced in a slide manner, Thereby improving the convenience of the shoe.

In general, in addition to the inherent functions of protecting and protecting the feet when worn, the shoes are required to have a function of making the walking more comfortable and enhancing the efficiency of various exercises and labor.

The foot of a person is slightly curved in an arcuate shape, so that it restrains the foot when walking, mitigates the impact load transmitted from the ground at the time of landing, and protects the nerve of the sole. Since it can be made comfortable to walk in the shape that matches the arch, it is made thicker by forming the rear axle or by attaching a bend to the area.

In fact, when the shoe is raised to a proper height, the muscles of the lower extremities such as the buttocks, the thighs, and the lower legs are stretched so as to be pulled upward, so that the legs are enhanced and the body shape is maintained properly. It has been proved through many experiments that it is effective to make it possible.

On the other hand, in order to walk comfortably while wearing the shoe, the stability of the landing operation and the impact load applied from the ground when the foot is taken should be more effectively absorbed.

In order to absorb the impact applied to the body from the ground, various outsole materials can be applied. When a sole made of a hard material such as a shoe heel is applied, the impact when the heel touches the ground is applied to the body It is reported that it is not suitable for a long walk or a heavy exercise.

On the other hand, when a sole with a thick and flexible material such as a sneaker outsole is used, the shock absorbing effect is relatively good, but since it takes some time to recover after the shrinking, it consumes more energy for the next operation after landing, There is a problem of getting worse.

Patent Literatures 1 to 5 disclose a conventional technique for enhancing the shock absorbing function of a sole of a shoe so that a metallic coil spring or an air bag is provided inside a rear shoe of a sole of a shoe so as to mitigate an impact load applied to the body from the ground during landing And the like.

However, the metal coil spring or the air bag applied to the above-described prior arts has a relatively large volume, and it is difficult to exhibit sufficient performance without increasing the height of the conventional shoe rear axle in consideration of sufficient shrinking motion There is a problem that the effect is low.

In this prior art, since the means having the shock absorbing function is built in the rear axle of the shoe so that it can not be separated, there is a problem that the user can not separate or replace it as needed, have.

Accordingly, the applicant of the present invention has made a decision to register a shock absorbing device for shoes, such as Patent Document 6, in order to solve the above problems.

Specifically, in the shock absorbing device for a shoe according to Patent Document 6, a shock absorbing device is provided between a rear bottom surface of the midsole and a rear upper surface of the sole that make up the shoe, absorbing the impact load transmitted from the ground surface to the body during walking However, it is intended to improve user convenience by allowing the user to freely separate and replace as needed.

However, in the case of Patent Document 6, there is a problem that the softness and the cushioning feeling of the shock absorber are insufficient and the impact protection effect as a whole is insufficient. Moreover, when a part of the shock absorber is arbitrarily separated and replaced, Not only the air permeability is insufficient, but also hygienic management such as sweat and bacteria propagate inside the shoe is difficult.

Therefore, the applicant of the present invention has filed a proposal (10-2014-0111839, 2014.08.26) of "Shock Absorbing Device for Shoe" improved on Patent Document 6, The shock absorbing device can be installed to absorb the impact load transmitted from the ground to the body during walking. By manufacturing the shock absorbing device with the TPU material, it is possible to improve the cushioning feeling with a very soft feeling, In addition, when it is necessary to change the ground state, the type of walking or movement, or the elasticity of other shoe, the user can easily and easily separate a part of the shock absorber as needed And furthermore, it is possible to further improve the usability thereof by making it possible to replace the shock absorber, and furthermore, a vent hole is formed on the upper side of the shock absorber, By applying the blood rear axle mesh material to the bottom surface, will be a vent effect is given to the interior of the shoe to manage the shoe is always clean and sanitary.

However, in the above-mentioned prior art patent, there is a problem in that it is somewhat uncomfortable to separate and replace the shock absorber by inserting the lower cushion plate into the upper cushion plate from the lower side to the upper side and then inserting a separate coupling pin .

Patent Document 1: Korean Patent Laid-Open Publication No. 10-2000-0024085 "Air cushion having a support pin structure for shock absorption, method of manufacturing the same, Patent Document 2: Korean Patent Laid-Open Publication No. 10-2000-0048904 "Shock absorption and energy return device for shoes" Patent Document 3: Korean Utility Model Publication No. 20-1996-0000187 "Shoe Heel Buffer" Patent Document 4: Utility Model No. 20-0225738, registered in the Republic of Korea "Shoe midsole with buffer function" Patent Document 5: Korean Utility Model Registration No. 20-0265533 entitled " Patent Document 6: Korean Patent Laid-Open Publication No. 10-2010-0104179 entitled "
