Description

Structure of heel for high-heeled shoes}

The present invention relates to a heel structure of high heels, and more particularly, to a heel structure of high heels worn by women to go out to stand out their legs.

In general, high heels are women's shoes having a thin and high heel shaft (1) constituting the heel, as shown in FIG. 1, the heel shaft (1) of the high heels in a flat form for attaching to the shoe bottom (5) It consists of an attachment portion (2) of the round and smooth curved body (3) and the heel shaft (1) protruding to form a long thin linear down the body (3), the tip of the heel shaft is attached to the tip (4) Has a structure.

Women's shoes with such a heel structure is preferred by women because they have a high heel (1) effect to look taller, lifting the buttocks to enhance the body shape of women, but on the other hand Due to the center of gravity difficult to grasp the center of walking, the weight of the heel axis (1) is loaded with most of the weight was a problem that the sprained ankle to lose or lose the center of self.

In addition, when wearing high heels, the conventional high heels are made of a hard material without elasticity of the heel shaft (1) itself, so that the impact generated from contacting the back of the foot, which is the first step of walking, is transmitted directly from the ground to the waist and knee to wear high heels for a long time. At the time, there was a problem that various side effects and disorders occurred in the lower back and knee joints.

Due to this problem, the heel structure of the structure that increases the ground area by increasing the cross section of the heel shaft is used. However, the heel structure has the disadvantage of being coarse and inconsistent with the shoe in appearance compared to the elongated heel structure. As a result, the overall weight of the shoes is increased, so there is a problem in that walking is unnatural and easy to feel tired.

The present invention has been made in order to solve the above problems, and the support portion of the hard material and the cushioning portion having an elastic force to combine to form a unit heel of a rectangular parallelepiped, and to form the heel by sequentially joining the unit heel The purpose of the heel is to provide a heel structure of the high heel to have a bending structure in which the upper and lower sides are symmetrical in shape similar to the neck bone structure.

3 to 4, the heel 40 is formed by bonding to the bottom surface 50 of the high heels worn by women. The structure of the heel 40 is a plurality of unit heels (70, 80, 90, 100, 110, 120, 130) is formed by sequentially joining down from the high heel bottom surface 50, the joint structure of the unit heels (70, 80, 90, 100, 110, 120, 130) is bent overall It has a structure.

As shown in FIG. 2, the unit hills 70, 80, 90, 100, 110, 120, and 130 are formed of a support 10 of a hard material and a buffer 20 of a soft material having a predetermined elastic force.

Here, the support portion 10 is made of a plastic material constituting the heel of a conventional high heel, and may further make the high heel 40 more beautiful by using wood or a light shiny metal.

In Figure 2, the structure of the support 10 has a top surface has a quadrangular shape, both sides of the support 10 has a shape that is chamfered at a predetermined angle from one side to the other side.

In addition, in FIG. 2, the front surface 140 and the rear surface 150 of the support 10 have different shapes. The front surface 140 of the support portion 10 is formed in a parallel rectangular shape, the rear surface 150 of the support portion 10 is formed in a rectangular shape like the front surface 140, but rather than the front surface 140 of the support portion 10 It will be formed in a smaller width.

The lower portion of the support, that is, the portion chamfered with the support 180 is a portion where the flexible buffer portion 20 is formed to be bonded.

Here, the buffer unit 20 typically uses a flexible plastic material and a new material having excellent elasticity and resilience, which constitute a part for shock absorption of sneakers or other shoes.

As shown in FIG. 2, in the structure of the shock absorbing part 20, the chamfered part 190 is formed on the upper surface of the shock absorbing part 20 so that the chamfered part 180 of the support part 10 is joined.

The lower surface of the buffer portion 20 is formed to have a width and a shape symmetrical to the upper surface of the support portion 10, the shape of both sides of the buffer portion, like the support portion 10 at a constant angle from one side to the other side down It has a shape that is chamfered.

In FIG. 2, the chamfered portion 190 of the upper surface of the buffer portion 20 is joined to the chamfered portion 180 under the support portion 20. The front surface 160 and the rear surface 170 of the buffer portion 20 have different shapes, respectively, and the front surface 160 of the buffer portion is formed to have a smaller width than the rear surface 170 of the buffer portion.

Here, when the support part 10 and the buffer part 20 are joined, the unit heel 40 of a rectangular parallelepiped shape is formed. In FIG. 3, the unit hills 70, 80, 90, 100, 110, 120, and 130 to which the support part 10 and the buffer part 20 are bonded have the same width and shape on both sides, the front side, and the rear side thereof, and the support part 10 and the buffer part. The width and shape of the upper and lower surfaces to which the 20 is joined are also the same.

As an example, the specifications of the unit hills 70, 80, 90, 100, 110, 120 and 130 are as follows.

2 to 4, the unit heel (70, 80, 90, 100, 110, 120, 130) is a vertical direction from the high heel bottom surface 50, that is, the vertical length (c ') of the unit heel is about 11mm, at this time, the length of one side ( c) the length of the support part 10 is about 11mm, the length of the buffer part is almost no, the other side length (c ') is about 7mm in length (d) of the support part 10, the length (e) of the buffer part is about 4mm to be.

In addition, when the unit heel (70, 80, 90, 100, 110, 120, 130) when viewed from the side, the length (a, a ') of the longitudinal direction of the high heel bottom surface 50 is formed about 22 ~ 24mm.

In addition, the lengths b and b 'across the longitudinal direction of the high heels in the unit heel are also formed equal to each other. Here, the lengths (b, b ') across the high heel longitudinal direction of the unit heel are formed to be equal to the width of the sole surface.

The numerical value of the above embodiment can be changed depending on the size and functionality of the high heels.

In addition, although the unit heel (70, 80, 90, 100, 110, 120, 130) in the above description as a whole is a rectangular parallelepiped, the front and rear of the unit heel, that is, the surface of the unit heel located in the direction perpendicular to the longitudinal direction of the high heel bottom surface is the functionality of the high heel It may be formed by changing the shape into a concave or convex shape for improvement.

As shown in Figure 4, the unit heel of the rectangular parallelepiped (70, 80, 90, 100, 110, 120, 130) is bonded in a direction perpendicular to the bottom surface 50 of the high heel to form a heel 40 structure.

This heel 40 structure as a whole has a bending structure, that is, a "C" shaped structure.

As shown in FIG. 3, the heel 40 has a first unit heel 70 bonded to the bottom surface 50 of the shoe, and one side (high heel) of the lower surface of the first unit heel 70. The second unit heel 80 joined by moving several mm to the side, and the third unit heel joined by moving several mm to one side from the lower surface of the second unit heel 80, the third unit heel 90 The fourth unit heel 100 joined by moving several mm from the lower surface of the bottom) and the fifth unit heel joined by moving several mm from the lower surface of the fourth unit heel 100 to the other side (rear of the high heel). 110 and the sixth unit heel 120 joined by moving several mm from the lower surface of the fifth unit heel 110 and the other side from the lower surface of the sixth unit heel 120 by several mm It is composed of a seventh unit hill 130 bonded.

3 to 4, the third unit heel 90 from the first unit heel 70 is gradually toward the front portion (one side) of the high heel 30 based on the fourth unit heel 100. The second unit heel 130 from the fifth unit heel 110 is gradually moved toward the rear portion (the other side) of the high heel 30 based on the fourth unit heel 100.

In addition, in FIGS. 3 to 4, the heel 40 structure has a first unit heel 70 joined to the high heel bottom surface 50 based on the fourth unit heel 100 and a seventh unit heel 130 contacting the ground. ) Has a vertically symmetrical structure, the second unit heel 80 and the sixth unit heel 120, the third unit heel 90 and the fifth unit heel 110 in the heel 40 structure Each of the fourth unit heels 100 has a vertically symmetrical structure.

Here, since the seventh unit heel 130 is a portion in direct contact with the ground, and the friction with the ground is severe, the buffer unit formed on the lower surface of the unit heel may be removed, and a cube shape may be formed only as the support portion of the hard material.

In FIG. 3, the distance g between each unit hill (for example, between the first unit hill and the second unit hill) is joined by moving the distance g several mm to one side or the other side. The moving joint spacing (g) of the liver is determined within a limit of about 2.5 to 3 mm depending on its width and shape, and the unit hills are arranged sequentially below this interval.

As shown in Figure 3, the structure of the heel 40 has a "C" shaped bending structure similar to the structure of the neck bone of the human body supporting the head of a relatively large load, so that the total load of the body It can be supported stably from below.

For example, each of the unit hills 70, 80, 90, 100, 110, 120, and 130 shown in FIG. 3 may be parallel to the chamfered portion 180 on the lower surface of the support 10 and the chamfered portion 190 on the upper surface of the buffer, respectively. It may be formed to join the support portion 10 and the buffer portion 20.

On the other hand, the features and principles of the heel 40 structure in Figures 2 to 4 are as follows.

First, when the body walks wearing the high heels 30 provided with the present invention, each of the unit heels 70, 80, 90, 100, 110, 120, and 130 constituting the heel 40 is generated from the body and the ground. To receive a constant repulsion.

However, the present invention can minimize the load of the body and the repulsive force from the ground in the heel 40 structure itself.

As shown in FIG. 3, the above-described effects can be achieved by a group of unit hills 70, 80, 90, 100, 110, 120, and 130 that are constituting the heel 40 and a "C" shape bending structure.

The principle of minimizing the load of the body and the reaction force from the ground will be described in more detail. In FIG. 3, the heel 40 is formed of a plurality of unit heels 70, 80, 90, 100, 110, 120, and 130.

The unit heel (70, 80, 90, 100, 110, 120, 130) is composed of a support 10 of a rigid material and a buffer 20 having an elastic force, respectively, the role of the support 10 in the heel 40 structure is a heel (40) ) Serves as a base frame to maintain and support the basic shape of the structure, and the role of the buffer unit 20 serves to absorb the shock generated during walking.

Therefore, when the body walks, a plurality of unit heel buffers 20 arranged between the heel 40 structures gradually absorb the impact generated while contacting the ground from the heel portion, and the impact of the ground is applied to the body. At the point of arrival, the impact is almost canceled by the role of the buffer part 20.

Because of the structure of the heel 40, in the present invention, the repulsive force from the ground, which has been pointed out as a problem in the general high heels, can effectively be offset to safely protect the knee joint and the waist of the body.

Here, the present invention should maintain a constant elastic force in the buffer unit 20 in order to prevent the heel is bent too much back when walking, as shown in Figures 2 to 3, unit heel (70, 80, When 90, 100, 110, 120, 130 has a height of 11 mm in the vertical direction (c ') of the high heel bottom surface 50, if a total of seven unit heels (70, 80, 90, 100, 110, 120, 130) are bonded to form a heel 40 structure, the height (f) is a total of 77mm, at which time the heel 40 is contracted to the elastic force of the unit heel buffer (e) to maintain the contraction range of about 2mm ~ 3mm usually.

In addition, the heel 40 structure, as shown in Figure 3, has a "C" -shaped bending structure as a whole, it is possible to stably support the load of the body from below.

The "C" shaped bending structure of the heel 40 has the effect of evenly dispersing the vertical stress resulting from the load of the human body. In addition, since the heel 40 has a structure in which the upper and lower parts are symmetrical, the load of the body can be more efficiently distributed in all directions, and the unit heel buffer 20 can be easily acted so as to facilitate the action of the buffer part 20. Make elastic force more efficient.

In addition, the heel of the "C" terrain bending structure stably supports the load of the upper portion by using the principle of the lever, and when the human body walks, the calf muscles of the human body contract and relax by the elastic force of the buffer part. It works.

According to the present invention, the heel is formed of a flexural structure, which is the neck bone structure of the body, so that a person can efficiently support and distribute the load when walking, and there are a plurality of shock absorbing parts having a constant elastic force between the heel structures. Minimize the impact of repeated heel contact in the heel structure, and more stable walking through this heel structure has an excellent effect of minimizing the impact generated on the waist or knee joint. In addition, even when walking for a long time can keep the foot comfortable, even women who are not familiar with high heels has the advantage of light weight of high heels can walk naturally.
