Description

Joint protection health shoes with high elastic shock absorption function {a shock absorbing health shoes}

The present invention relates to a shoe, and more particularly, a joint having a high elastic shock absorbing function that can be worn in a comfortable state for a long time, as well as absorbing a shock applied to a foot when walking, jogging or running in everyday life. It is about protection health shoes.

In general, shoes are used to walk on the foot, which is indispensable in daily life, and are widely used in various ways such as shoes, sneakers and other professional sports shoes and indoor shoes.

In addition, recently, shoes that can be worn more comfortably and help health are being developed.

These various shoes are being developed because modern people are living with various physical problems such as obesity due to lack of exercise and sufficient nutrition as the means of transportation are diversified due to the development of science and industrialization.

Therefore, modern people perform various sports such as walking, jogging or climbing for the purpose of health promotion.

At this time, the biggest problem in the exercise or walking, such as the shoe itself is not enough cushioning function will be a problem to give a joint to the cartilage and spine, cervical spine of the joint.

In order to solve this problem, in the prior art, the application number 10-2006-55200, 20-2006-15945, 10-2004-41282, 10-2004-47371, etc., through the spring to exert the effect of the buffer Shock absorbing shoes have been proposed.

However, these buffer shoes have the following problems.

First, since a plurality of springs and the upper and lower plates for supporting them are interposed, the height of the shoes is increased, thereby deteriorating the appearance and impairing the stability of the movement or walking.

Second, in general, the use of a cylindrical coil spring does not exert a great cushioning effect due to the limitation of the working distance, and when worn for a long time, the adjacent winding of the spring is damaged by contact or breakage and loses elasticity. The problem is caused.

Third, there is a problem in that the assembly is composed of a large number of parts, the assembly is inferior and cost increases.

Fourth, in the case where the spring is embedded in the urethane (PU), the elastic force of the spring itself is impeded by the urethane, and when the spring is formed at the same time as the PU, the heat treatment of the spring is released and the elasticity is lost so that a sufficient buffering effect cannot be exerted. When the PU material is in contact with water for a long time, hydrolysis occurs, and when the molding is broken, the spring is loosened.

An object of the present invention for solving the above problems is to provide a sufficient cushioning effect by arranging a plurality of springs without having to increase the overall height of the shoe, as well as a problem that the buffering effect of the spring is poor even when worn for a long time In particular, the object of the present invention is to provide a joint-protective health shoe having a high elasticity shock absorbing function that can be easily assembled and can reduce costs.

Joint protection health shoes having a high-elasticity shock absorbing function according to the present invention for achieving the above object, the sole is formed with grooves of a predetermined depth in the heel and heel portion; A cushioning pad seated on an upper surface of the sole, having a plurality of acupressure protrusions protruding from an upper surface thereof, and a plurality of engaging protrusions provided on a lower surface thereof; A conical coil spring interposed between the lower side engaging projection of the buffer pad and the front heel side groove of the sole to exert a buffering force; It is interposed between the groove of the heel portion of the outsole and the buffer pad exerts a cushioning force, and a cushioning member consisting of a buffer spring interposed between the upper and lower plates and between them.

One preferred feature of the present invention is that the heel of the sole has a convex cross-sectional shape toward the bottom.

Another desirable feature of the present invention is that the sole which is coupled to the lower end of the conical coil spring is provided with a rib that wraps the outer surface of the conical coil spring to prevent flow and reinforces rigidity.

Another preferred feature of the present invention, the middle window is configured to separate the front heel and heel, the front heel side buffer pad is connected to the connecting ribs while the acupressure protrusion and the engaging projection is provided integrally at a position corresponding to each conical coil spring ( ribs connected to each other and having a cross-sectional shape of a mesh.

As expected effects due to the above-described features of the present invention, a plurality of conical coil springs are interposed between the shock absorbing pad and the sole, thereby providing sufficient cushioning effect even in a short working space. Since the part where the windings are not in contact with each other does not occur, it maintains elasticity and restoring force which is a unique function of the spring, and shows stable cushioning effect for a long time.

In addition, the structure is simple, so as to improve assembly performance and reduce cost, and the thickness of the sole can be made thin so that the height of the entire shoe is not increased. The hatch is prevented to have problems, it is possible to promote the purchasing power according to the improvement of the productability of the product.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

1 is a perspective view of the coupling relationship of the joint protection health shoe according to the present invention, Figures 2 and 3 are cross-sectional views. 4 is a perspective view showing another embodiment of the present invention.

As shown therein, the joint protection health shoes according to the present invention are largely divided into a sole 100, a buffer pad 200, a conical coil spring 300 and a buffer member 400.

First, looking at the structure of the sole 100, the groove portion 110, 120 to a predetermined depth is formed in a portion corresponding to the heel and heel of the foot.

At this time, in forming the groove portion 110 in the heel portion, since the thickness of the heel portion of the conventional shoes is difficult to form this, if the overall height is formed, there is a problem that damages the appearance.

In order to solve this problem, the front heel portion of the sole 100 preferably has a convex cross-sectional shape toward the lower side.

Through this, it is possible to obtain a sufficient thickness to form the groove 110, and also to prevent the problem that damages the appearance.

The buffer pad 200 is formed of a material having a predetermined elastic force and is a portion seated on the upper surface of the sole 100.

A plurality of acupressure protrusions 210 protrude from the upper surface of the buffer pad 200, and the acupressure protrusions 210 pressurizes the sole surface of the user to exert an effect of acupressure, thereby promoting a user's health promotion. Do this.

On the other hand, the lower surface of the buffer pad 200 is provided with a plurality of coupling protrusions 220 at predetermined intervals.

The coupling protrusion 220 not only performs a function of supporting the upper end of the conical coil spring 300 to be described later, but also performs an additional function of more effectively exerting an effect of cushioning due to its soft material property.

In addition, the coupling protrusion 220 serves to prevent the conical coil spring 300 from sagging below the height when the conical coil spring 300 is elastically deformed toward the bottom surface, that is, the sole 100.

In other words, when the coupling protrusion 220 contacts the sole 100 at the time of a strong impact, the coupling protrusion 220 blocks the lowering below the elastic limit of the conical coil spring 300.

Next, the conical coil spring 300 is installed between the groove 110 of the front heel side sole 100 and the coupling protrusion 220 of the heel side shock absorbing pad 200, that is, the coupling protrusion (as described above). As the upper end is coupled to the lower end 220 and seated on the sole 100, the diameter is gradually widened from the upper end toward the lower end, that is, it is formed in a conical shape.

Due to the conical coil spring 300, the winding portions of the spring are not in contact with each other in the buffering process so that the elastic deformation generated in the conventional spring is not generated at all.

In addition, even if the overall height of the conical coil spring 300 is not formed high, sufficient buffering effects are exerted.

 At this time, the portion of the sole 100 in contact with the lower end of the conical coil spring 300 is a certain time is elapsed and wear occurs occurs when compared to other parts of the shoe is a problem that is broken first.

In order to prevent this, the groove 110 of the sole 100 coupled to the lower end of the conical coil spring 300 is wrapped around the outer surface of the conical coil spring 300 to prevent flow, ribs to reinforce rigidity; It is preferable to provide 500 integrally, and it is more preferable that the ribs 500 are formed to be interconnected as a whole.

Finally, the heel buffer member 400 is interposed between the groove 120 of the heel portion of the sole 100 and the buffer pad 200 to exert a buffering force, and as is known, the upper and lower plates 410 and 420. ) And a buffer spring 430 interposed therebetween.

On the other hand, Figure 4 shows another embodiment of the present invention.

This takes a structure in which the shock absorbing pad 200 is separated into an heel part and a heel part.

To explain this in more detail, the rear shock absorbing pad has the same shape as a normal middle window, and the front heel side shock absorbing pad 200 ′ is coupled to the acupressure protrusion 210 and the engaging protrusion at a position corresponding to each conical coil spring 300. The 220 is integrally provided and connected through the connecting rib 700 so as to have a mesh-shaped cross section.

As described above, the structure of the shock absorbing pad 200 ′ is separated from the structure of the integrated shock absorbing pad 200 because of the area occupied by the shock absorbing pad 200 when the upper and the sole 100 are adhered to each other. There is a possibility that the upper and the sole 100 is separated by the area is narrowed, and the foot is in direct contact with the double contact through the buffer pad 200 and the insole 600, so that it does not bend well This is because it causes difficulty in walking and does not directly feel the effect of cushioning.

On the contrary, when the shock absorber pad 200 is separately configured, the conical coil springs 300 operate independently of each other, that is, they naturally move according to the sole contact surface, so that the shock absorbing effect is directly felt and soft. Walking is possible.

Unexplained reference numeral (H) is an air circulation passage for circulating the air inside the shoe by communicating the grooves (110, 120) with each other as is known.

The air circulation passage (H) is a known technique and will not be described in detail.

In addition, the reference numeral 600 is also seated on the upper surface of the shock absorbing pad 200 and the sole 100 and formed of a soft material, that is, a kind of insole.

Joint protection health shoes having a high elastic shock absorbing function according to the present invention configured as described above, the front and rear portions of the sole 100, that is, the grooves 110, 120 are formed in the front heel and heel portion buffer pad 200 located on the upper surface Conical coil spring 300 is interposed on the engaging protrusion 220 formed in the front heel of the), the groove portion 120 of the heel is provided with a buffer member 400 is provided by the buffering effect during walking or exercise You can get it.

In addition, as mentioned above, the conical coil spring 300 exhibits sufficient cushioning effect even when worn for a long time.

In addition, even when the conical coil spring 300 is arranged in an arrangement, the coupling is made without forming a large height of the sole 100, so that the problem of having to form a conventional shoe height as a whole does not occur.

In addition, the rib 500 is provided on the sole 100 to prevent the flow of the conical coil spring 300, and to obtain an effect of suppressing abrasion generated at the site where they are coupled.

While the invention has been shown and described in connection with specific embodiments thereof, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.
