The Heels for Rear Hoof of High-heeled Shoes}

The present invention relates to a shoe heel for high heels, and more particularly, to absorb the impact applied from the ground by using a shoe heel, walking, or cantilever movement, which is replaced with the heel of a high heel, and prevents slipping and also prevents slipping as described above. By making it easy, it can reduce the fatigue caused by walking or canal movement to people wearing high heels, prevents excessive stress on joints, prevents safety accidents due to slipping, and improves productivity and quality with ease of production. High heels heels.

In general, the height of the heel of the shoe is about 3 ~ 5㎝ is appropriate, and more than that has been reported to the medical community to give a burden to the human body. However, for the reason that the shoes look taller or fashion, forcing women to raise the height of the heel of shoes, many problems are exposed.

In other words, when studying the basic gait of the human body, four steps should be naturally performed: when the heel is grounded, when the entire sole of the foot is grounded, when the heel is raised from the ground, and when the ground is pushed back. Only balanced walking can be achieved.

The high-heeled women's shoes, that is, high-heeled shoes, give rise to the overall musculoskeletal system such as ankles and knees due to the impact that is grounded with the ground when walking, thereby increasing energy consumption and muscle fatigue.

In addition, when the high heels of the appropriate height are worn, excessive load is applied to the forefoot and the ball of the foot, resulting in unnatural walking, such as deformation of the shape of the foot and abnormality in the spine, which may impair the balance of the human body. I'm doing it.

Shoe bends coupled to the heels of the high heels, the most to support the body of the woman when walking or walking, there is a problem that must be easily replaced and replaced frequently.

That is, the shoe heel is mainly made of a hard synthetic resin material to prevent easy wear, but its size is so small that it can not withstand the wear caused by supporting the female body to be replaced frequently.

In addition, due to the hard plastic material and very small size is easily slipped, there is also a problem that causes a lot of safety accidents, such as a woman slips during walking or ward can hurt ankle or fall, hurt the hips or wrists.

In order to solve the above problems, various configurations have been developed that can absorb the shock to the shoe heel coupled to the heel of the high heels, Republic of Korea Patent Publication No. 2009-0029254 (published March 20, 2009, name In the case of high heels, a gong in which a fixing pin is vertically installed on the heels is installed on the bottom of the heels of the heels so as to be replaced. It is installed so as to be integral, but the heel cover is a tough and elastic rubber material characterized in that the vertical portion protrudes upward on the upper circumference of the bottom.

According to the above, when walking with high heels, the heel cover is in contact with the ground first, and the bottom of the heel is not in contact with the ground so that the noise and impact is reduced and to prevent slipping.

Although the heel cover made of rubber is installed in a detachable manner, when the heel cover is coupled to the heel by the insert method, the heel cover does not withstand the friction caused by the slip and the heel cover is easily removed from the heel. .

In addition, the heel cover is formed integrally with the heel by insert injection molding. However, when the injection heel cover of rubber material is inserted into the heel to which the fixing pin is coupled, the heel cover made of rubber is not completely joined to the hard heel. In addition, there is a problem that the heel cover is easily removed from the heel without bearing the friction due to the slip.

In addition to the above-described techniques, various techniques have been disclosed, but it is difficult and expensive to manufacture due to a complicated configuration, which leads to a reduction in consumption due to high consumer prices, and heels of the heels become heavy, which imposes a lot of pressure on walking or doublet operation. There is a problem.

The high heels refer to shoes in which the heel portion is lifted high. In the broad sense, the high heels refer to high-heeled shoes, but especially the women's shoes.

In the lower part of the heel 1 of the high heel, a fixing hole 2 for replacing the shoe heel A is formed, so that the worn shoe heel A is replaced with the new shoe heel A using the fixing hole 2. ) Is being used.

At this time, the lower part of the heel 1, one side is made of a straight line and the other side is made of a semi-circle.

Hereinafter, one side refers to the front side of the high heels, and the other side refers to the rear side of the high heels.

The shoe heel A is composed of a fixing pin 10, the elastic portion 20 and the hard portion 30.

First, the upper side of the fixing pin 10 is made of a circular shaft, the coupling portion 12 is made of a thickness corresponding to the fixing hole (2) of the heel (1) is provided, the lower side is formed by the upper side light The head 11 is provided.

Thus, the coupling portion 12 of the fixing pin 10 is inserted into the coupling hole (2) is coupled to easily replace the shoe heel (A).

The fixing pin 10 as described above is made of a metal, the upper outer surface is formed with irregularities or a plurality of projections or knurling to be firmly fixed when inserted into the fixing hole (2) of the heel (1) Ham is as well known.

That is, the fixing pin 10 is composed of the upper coupling portion 12 and the lower head portion 11, the coupling portion 12 is a portion that is inserted into the fixing hole 2 of the heel 1 , The head portion 11 is a part which makes the bonding portion between the hard portion 30 and the fixing pin 10 excellent when injection molding the hard portion 30 to complete the shoe heel A.

On the other hand, the coupling portion 12 is provided with a coupling surface 13 forming a plane vertically. That is, the coupling portion 12 is formed in a cylindrical shape, by processing the coupling surface 13 made of a vertical plane on the outer periphery of the coupling portion 12 is formed. At this time, the coupling surface 13 is not only to be formed on the outer periphery of the coupling portion 12, but may also be formed in two or more, simple design deformation for the number of formation of the coupling surface (13) Will all belong to the scope of the present invention.

Although the coupling surface 13 will be described in detail later, the hard part 30 is injection molded to the lower portion of the fixing pin 10 and the elastic part 20 is injected after the hard part 30 is injection molded. When molding, the fixing pin 10 is rotated in the mold due to the injection-molded pressure to prevent a defect from occurring.

At this time, in forming a plurality of the coupling surface 13, it should be formed so that the set diameter of the coupling portion 12 can be maintained in one or more directions.

This is because the set diameter of the coupling portion 12 is an essential diameter to be inserted and fixed in the fixing hole 2, the coupling surface 13 should be formed in a state where there is a part capable of maintaining the set diameter. .

On the other hand, the width of the coupling surface 13 is shown to form a large, but this is for emphasis, and may be formed smaller or larger, of course, all such simple modifications will be within the scope of the present invention.

The hard part 30 is injection molded to surround the head portion 11 of the fixing pin 10 and is provided by injection molding with a hard rubber material or urethane.

In this case, the hard part 30 is molded of a hard rubber material or urethane so that its hardness is 70 to 100 based on the maximum of 100.

Therefore, since the hard part 30 surrounds the head portion 11 of the upper and lower light beams, the bonding force with the fixing pin 10 is excellent, and the hard part 30 is made of a hard rubber material or urethane. By being molded in, the hard part 30 and the fixing pin 10 will be combined as if integrated.

On the other hand, the outer periphery of the hard portion 30, one or more grooves 31 are formed, the groove 31 is formed by being dug vertically to the outer periphery of the hard portion 30, as shown in the figure It is preferable to form a plurality of pieces around the outer circumference of the hard part 30.

The reason why the groove 31 is formed is that when the elastic portion 20 is wrapped around the hard portion 30, the bonding force between the hard portion 30 and the elastic portion 20 is excellent and at the same time, This is to prevent the elastic portion 20 from being twisted about the hard portion 30.

As described above, the elastic part 20 is formed by injection molding the soft rubber material surrounding the hard part 30, and has a soft rubber material such that the hardness thereof is 40 to 60 based on the maximum of 100. It is provided by injection molding.

In this case, the hard part 30 is injection molded, and the elastic part 20 may be injection molded while covering the entire hard part 30 as shown in the drawing, and the hard part may protrude from the upper surface of the hard part 30. Of course, the elastic portion 20 may be injection-molded while wrapping only the side circumference and lower surface of the portion 30, and all of these simple design variations will be within the scope of the present invention.

On the other hand, the elastic portion 20 is the injection molding while filling the groove 31 of the hard portion 30 at the same time to wrap the hard portion 30, the hard portion 30 and the elastic portion 20 is The firmly coupled state is maintained, and consequently, the elastic part 20 is firmly provided at the bottom of the fixing pin 10.

Shoe heels (A) made as described above, by the elasticity of the elastic portion 20 itself made of a rubber material, impact resistance and viscosity, minimizing noise and slip when walking or striking hard and slippery surfaces such as marble It also reduces shock and is not easily worn due to its tough nature.

In addition, even on rainy days or other slippery places, it is possible to perform stable walking or vowel operation without slipping, and noise is not generated due to shock absorption with the ground, thereby preventing discomfort to others.

On the other hand, the fixing pin 10 is made of a rod, such as a metal wire, as it is known that a variety of methods are commonly used, a detailed description of how to manufacture the fixing pin 10 Will be omitted.

However, when manufacturing the fixing pin 10, of course, one or more coupling surfaces 13 should be formed on the outer circumference of the fixing pin 10.

In the state in which the fixing pin 10 is prepared as described above, the fixing pin 10 is inserted backward into the mold 40 of the injection molding machine, as shown in FIG. 3, and the hard part 30 is disposed below the fixing pin 10. Will be injection molded.

That is, a fixing hole 41 corresponding to the coupling part 12 is formed in the mold 40, and the fixing hole 41 is provided with a fixing surface 42 corresponding to the coupling surface 13. Insert the upper part of the fixing pin 10 into the fixing hole 41, and insert the fixing pin 10 to match the coupling surface 13 and the fixing surface 42.

At this time, the head 11 of the fixing pin 10 is located on the upper side, of course.

As described above, when the coupling surface 13 and the fixing surface 42 are in contact with each other, the fixing pin 10 may not rotate in the fixed mold 40 and adheres to its position.

And when the injection molding the hard part 30 while wrapping the head 11, the state as shown in Figure 4, the hard part 30 is wrapped around the head 11 of the fixing pin 10 Molded, but injection molded in a state in which the groove 31 is formed in a number of places on the outer circumference.

On the other hand, since the hard rubber material or urethane for injection molding the hard part 30 is commonly used, a detailed description thereof will be omitted.

When the hard part 30 is formed by injection molding surrounding the head 11 of the fixing pin 10 as described above, as shown in FIG. 5, the fixing hole 41 of the mold 40 is formed on the upper part of the fixing pin 10. It is coupled to the) to wrap the hard portion 30 is to injection molding the elastic portion 20.

In this case, the depth of the fixing hole 41 is deeper when injection molding the hard part 30, and the depth of the fixing hole 41 is not deep when injection molding the elastic part 20.

This, when injection-molding the hard part 30, the coupling part 12 is inserted a lot to wrap around the head portion 11 of the fixing pin 10 and injection molding the hard part 30, fixed Most of the engagement portion 12 of the pin 10 must be inserted.

When the elastic part 20 is injection molded, since the hard part 30 is formed while surrounding the head 11, the depth of the fixing hole 41 when injection molding the elastic part 20 is It is to be formed to a depth smaller than the depth of the fixing hole 41 when injection-molding the hard part 30.

Meanwhile, as shown in FIG. 5, when the coupling part 12 of the fixing pin 10 is inserted into the fixing hole 41 of the mold 40, the hard part 30 integrated with the fixing pin 10 is upper side. It is located at.

Then, the injection molding is made of a soft rubber material to wrap the hard part 30 and injection molding the elastic part 20.

At this time, the hard part 30 is one side is a straight line and the other side is made of a semi-circular shape, when the hard part 30 is moved when the injection molding the elastic part 20 while wrapping the hard part 30, the defect occurs Done.

That is, when the hard part 30 is moved and twisted when the elastic part 20 is injection-molded, the hard part 30 is visible on the outer surface of the elastic part 20 formed in a straight line and the other side in a semicircular shape. As a result, the centers of the hard part 30 and the elastic part 20 do not coincide with each other, thereby causing a defect.

However, the hard part 30 is in a state in which the fixing pin 10 is integrated, and the coupling part 12 of the fixing pin 10 is fixed to the coupling surface 13 and the fixing surface 42 in contact with each other. Since it is inserted into and coupled to the (41), the fixing pin 10 is prevented from rotating by the coupling surface 13 and the fixing surface 42 so that the hard part 30 does not move even under pressure due to injection molding. Therefore, the defect does not occur.

On the other hand, since the height of the elastic portion 20 is usually manufactured and used 5mm, the thickness of the hard portion 30 in the present invention is formed to 1.5mm ~ 2mm, the lower surface of the hard portion 30 The thickness up to the lower surface of the elastic portion 20 is 2.5mm ~ 3mm, the thickness from the upper surface of the hard portion 30 to the upper surface of the elastic portion 20 is preferably formed to 0.5mm. .

In this case, the height of the elastic part 20 may be manufactured to be 6 mm. At this time, the thickness of the hard part 30 is 2 mm to 2.5 mm, and the elastic part 20 is formed on the bottom surface of the hard part 30. The thickness up to the lower surface of the portion 20 is 3 mm to 3.5 mm, and the thickness from the upper surface of the hard part 30 to the upper surface of the elastic part 20 is preferably 0.5 mm.
