Technical Field

The present invention relates to a shock absorbing heel having a shock absorbing means capable of relieving a load applied to a sole of a foot when walking, and more particularly, to a shock absorbing heel having a shock absorbing means, which is attached to a high-heeled shoe, and which includes: the outer heel is fixedly arranged behind the sole of the high-heeled shoe (shoe); the spring is arranged on the upper side of the inner heel and is connected with the inner side of the outer heel; and a sole heel which is fixedly arranged at the lower end part of the inner heel and can be replaced, wherein the lower end part of the outer heel is inserted with a cylindrical protective cap, so that the lower end part of the inner heel is prevented from being exposed outside, a fixed cover connected with the upper part of the spring and the inner heel is inserted into the inner side of the outer heel, and the outer heel slides up and down through the spring during walking, thereby relieving the impact.

Background

Women like to wear beautiful high-heeled shoes, and the desire of each woman to wear such high-heeled shoes is that the completion of fashion is called to match a pair of high-heeled shoes.

In particular, high-heeled shoes, which can increase the height, thereby enabling the body and clothes to be matched more beautifully, and can freely exhibit heightening and fashion designs without limitations, are favored from teenagers to elderly women, and have become life necessities that they prefer to wear.

Thus, high-heeled shoes have the advantages of being heightened, decorating clothes and statures, being more fashionable, and being matched with the charm which is not hindered, but simultaneously, the following problems exist: since the heel of the high-heeled shoe is high, impact force is applied to the foot, knee, waist and the whole body, thereby causing foot pain, general discomfort, simultaneously inducing problems of foot diseases, knee and back pain, etc., or causing damage to joints of the foot, knee and waist.

In order to solve the above-mentioned problems, some techniques have been proposed in the related art, and for example, there are disclosed techniques in which a general elastic member such as rubber is inserted into the heel, or an elastic device such as a spring is used.

In the prior art that has been disclosed, utility model No. 20-0403451 "woman style cushioning shoe", which includes a cushioning device, the heel of the cushioning shoe is pasted and fixed on the rear end of the sole, and has a proper height, and can function as the heel, when walking, the impact applied to the heel is reduced to the utmost by elastic potential energy, the cushioning device includes: a housing having a barrel shape with an upper portion closing a lower opening, wherein upright guide holes are formed through upper ends of opposite outer edge surfaces, and cushioning members are provided on upper and lower surfaces of the guide holes, respectively; a lifting member of a tubular type provided at an upper end of an outer circumferential surface thereof with pin-shaped locking protrusions, respectively, facing each other, the pin-shaped locking protrusions being located inside the guide hole so as to be lifted or lowered at an appropriate height inside the housing; a fixing member formed in a shape having an open upper end and a closed lower end, and fixed to a lower end of an inner circumferential surface of the elevation member; and an elastic member which is located between the top plate in the housing and the bottom surface of the fixing member and applies elastic potential energy to the fixing member.

In addition, the "shock absorbing heel" of the prior utility model No. 20-0393493 provides a shock absorbing heel which has a strong buffering power due to the hydraulic pressure applied to the sole attached to the heel, thereby being capable of alleviating the shock transmitted to the ankle and the knee when walking.

As described above, in the conventional shoe, since the cushioning member is installed in the sole, it is difficult to manufacture the heel provided with the cushioning member, and the installation structure is complicated, so that the process of installing the cushioning member is also complicated. Due to such difficulty, the structure of the shoe needs to be changed to install the cushioning member, and thus additional manufacturing equipment needs to be purchased.

In addition, the conventional heel has a problem in that it is difficult to easily install or detach the sole for use or to replace or repair parts for reuse, thereby causing a great economic loss and deteriorating durability and convenience thereof.

In order to solve this problem, the present applicant filed patent application 10-2019-.
