The present invention forms a plurality of recessed grooves and flow projections respectively corresponding to the upper and bottom surfaces of the lower sole of the shoe, and is inserted into the recessed groove of the lower sole by penetrating the upper sole stacked on the upper surface of the lower sole. It consists of insertion protrusions, but the teeth provided on the outer peripheral surface of each insertion protrusion and at the same time separate the insertion protrusions in at least two parts along the up and down direction, when the insertion projections press the bottom of the recess groove, the flow projections to the bottom In addition to preventing the slip while being in close contact, the incision portion of the insertion projections, so as to absorb excessive compressive force, relates to a shoe sole member.

The shoes that have been developed as a person walks have developed dramatically with the development of science and technology and various new materials. Today, shoes for various purposes are suitable for various activities such as walking, mountain, body correction, and specific exercise. Are being made.

In particular, as the importance of health has risen, sports shoes have undergone rapid development, and new materials and structures have been continuously developed. However, in terms of physical health, the first thing to solve in terms of physical health is breathability. It is a problem of cushioning and cushioning, which is more important in terms of physical health than breathability. If the shoe is not cushioned, the foot is not only easily felt, but also the impact of contact with the sole of the shoe and the ground causes the brain to pass through the spinal cord. The shoes must have sufficient cushioning properties because they are known to have a bad effect on the body.

Although the problem of cushioning has been solved in many parts by the development of various materials having excellent shock absorbing properties, it is not possible to solve all of the problems of cushioning by using only materials having excellent cushioning properties.

In other words, the cushioning properties of the shoes should be dependent on the magnitude of the impact force applied to the shoes. In the case of a simple walking or jogging shoe, the cushioning problem can be solved only by the soft and fluffy material, but such as basketball or volleyball In the case of sports shoes accompanied by movement and jump, it is not easy to solve the problem of cushioning by material alone.In the case of sports shoes, various cushion structures such as an air chamber are applied to the inside of the shoe sole and the cushioning material is excellent Is used in parallel.

As described above, the cushioning properties of the shoes should be different according to the use of the shoes, and in the case of athletic shoes, in particular, the bottom of the shoe sole has to be in contact with the floor in order to improve adhesion to the bottom.

That is, in almost all conventional shoes, the entire bottom of the sole is almost in contact with the floor, and the impact of the contact between the sole and the sole of the shoe is transmitted to the brain through the rear end of the sole, the heel, and the spine. Shoes with built-in air shock absorbers (Korean Utility Model Publication No. 95-2742) or elastic bodies (Korean Registered Utility Model Publication No. 226048) have been developed. By combining the material with excellent cushioning property in the heel portion, the shock transmitted to the brain is reduced as much as possible by improving the cushioning property of the shoe.

However, since the contact between the rear end and the bottom of the sole bottom of the shoe can not be avoided during walking, the fundamental impact caused by the contact of the rear end and the bottom of the sole bottom cannot be reduced.

In order to solve the problems of the conventional shoe, the rear end of the bottom of the shoe sole is not in contact with the floor, or the heel portion of the shoe sole is removed so that the contact is very flexible. Shoes have been developed.

That is, the shoe, as shown in Figure 1, by inclining the heel portion of the shoe sole 11 upward, so that the end portion of the bottom surface of the sole by the height (h) lifted away from the floor (G) As such, the sole of a shoe having such a structure has a thicker portion of the insole portion, that is, the front portion of the sole, in order to maintain the upper surface in a state similar to a conventional sole in which the rear end portion is not lifted. As a result, the cushioning property is improved as compared with the conventional sole, and the contact area between the sole and the sole moves forward to reduce the fundamental impact strength due to the contact between the rear end of the sole bottom and the sole.

Moreover, the shock absorption is maximized by interposing the cushion member 12 with good shock absorbency between the upper rear end of the upwardly inclined sole 11 and the rear rear end of the shoe body 13.

However, the shock absorbing structure or cushion member applied to most conventional shoes, including a shoe lifted the bottom end of the rear end of the sole, has the problem of showing the same shock absorbing behavior even if the amount of impact changes.

That is, the cushion member or the shock absorbing structure applied to the shoe merely absorbs the shock in such a manner that only the amount of compression increases or decreases according to the amount of impact, and the amount of impact that can be absorbed because the impact absorption behavior does not change according to the amount of impact. It is limited, the shock absorption range also has a problem that must be limited.

In addition, in the case of a shock absorbing structure applied to the sole of the entire shoe including the sole for absorbing the shock, the structure is generally a composite, or a structure that combines a separately manufactured air tube, such as a low manufacturing productivity, to increase the manufacturing cost I have a problem.

In addition, the adhesion of the sole to the floor should be considered along with cushioning for safe walking and exercise, but the above-described conventional shock absorbing structure or member is mainly aimed at improving the cushion.

Therefore, in order to improve the adhesion to the floor together with the cushioning,

An outsole having a plurality of protrusions on a bottom thereof, the outer ring protruding from the top of which the protrusions are located;

A midsole stacked on an upper surface of the outsole and having a plurality of through holes formed therethrough;

An insert consisting of a plate laminated on the upper surface of the midsole and a plurality of protrusions protruding downward from the bottom of the plate and penetrating through the through holes of the midsole and inserted into the outer ring;

Shoe sole has been developed consisting of a lasting board and the like laminated on the upper surface of the midsole including the insert.

However, the shoe sole has a structure in which the protrusions of the insert are integrally connected by the plate body, so that the adjacent protrusions are interlocked with each other to the up and down movements of one of the protrusions, thereby preventing the individual movement of each of the protrusions, thereby accurately moving the external load. This difficulty is difficult, and each of the protrusions simply penetrates through the through holes of the midsole, and the midsole only serves as a simple cushion material that exhibits only the upper and lower elastic force required for the movement of the insert protrusion.

In addition, since the protrusion of the bottom of the outsole has a circular and asymmetrical rectangular shape, and the protrusion of the insert is closely inserted into the inner circumferential surface of the outer ring, the external load transmitted to the protrusion through the protrusion is injected to the entire cross-sectional area. There is a drawback that the effect of improving the adhesion to the floor is not great because the degree of downward protrusion of not enough.

That is, the shoe sole is a shoe that focuses more on cushioning property than on adhesiveness.

In addition, in general, shoes, especially the bottom end of the sole bottom wears most severely, the bottom of the rear end of the badly worn outsole can cause unsafe posture during mountain climbing or exercise, as well as appearance, Since it is not desirable, you have to buy new shoes. That is, there is a disadvantage that the service life of the shoe is shortened.

Therefore, if necessary, it is possible to extend the service life of the shoe by combining the detachable spike member made of metal or synthetic resin, and to replace only the worn spike member, but a large number of soles such as soccer shoes or golf shoes If the spike member is coupled there is a problem that is not suitable for walking.

The present invention has been devised to solve various problems of the conventional shock absorbing structure or the combined structure of the member and the detachable spike member, etc. applied to a shoe sole to improve cushioning properties and adhesion to the floor. While the adhesion to the floor is properly adjusted, the shock can be absorbed more efficiently, and at the same time, by attaching the spike member in a replaceable manner, in particular, it provides a footwear floor member that can be applied to hiking boots or golf shoes for winter. There is a purpose of the present invention.

The object of the present invention is achieved by a plurality of projections cut in the up and down direction, the teeth formed on the outer peripheral surface and the spike member detachably coupled to the bottom of the sole.

The shoe bottom member of the present invention, the lower outsole in contact with the bottom so that the impact is first absorbed, the second impact absorption is made by the upper outsole laminated on the upper surface of the lower outsole, while penetrating the upper outsole The insertion protrusion protrudes downwardly from the bottom of the lower sole to enhance the adhesion to the floor, and allows the third projection to be absorbed by the elastic deformation of the insertion protrusion, and then the insertion protrusion quickly returns to its original shape. There are technical features to this.

In addition, by additionally combining a plurality of detachable spike members on one side of the lower sole, particularly at the rear end of the bottom, when the rear portion of the sole which is severely worn is excessively worn, a new spike member is replaced or a thickness when playing golf, etc. It is another feature to increase the posture stability by combining a thick member, that is, a high spike member in the appropriate position of the rear end of the sole bottom.

In this case, the spike member does not mean only a relatively sharp shape such as a nail or a pin, and the cross section of the spike member is relatively several times smaller than the area of the bottom of the lower sole, and thus is coupled to the bottom of the lower sole. The spike member is defined as meaning a member having a shape such as a protrusion protruding from the bottom of the lower sole.

As described above, the upper and lower soles of the shoe and the bottom of the shoe of the present invention to improve the adhesion to the bottom while absorbing the impact three times by the insertion and flow projections,

A lower outsole having a plurality of recessed grooves and flow projections, respectively, corresponding to the upper and lower surfaces of the longitudinal front part corresponding to the front part of the foot up and down 1: 1;

An upper outsole stacked on the lower outsole and having a plurality of through-holes located therein;

A plurality of insertion protrusions penetrating through the through holes of the upper sole and inserted into the recess grooves of the lower sole;

It consists of a plurality of spike members and the like detachably formed on the rear portion of the lower sole, that is, the bottom of the heel portion, looking at each as follows.

The lower sole serves as a primary absorber of the impact in a state in which the bottom surface is in contact with the floor, and a plurality of fixing protrusions and flow protrusions are formed on the bottom of the lower sole, respectively, and the fixing protrusion is formed at the front of the lower sole. It is a simple downward projecting structure that moves with the bottom.

However, the flow protrusion may move together with the bottom of the bottom sole, but may move independently. The flow connecting portion of the “∩” shaped cross section is formed between the upper outer circumferential surface of the flow protrusion and the bottom of the bottom sole to form a closed loop like a ring. do.

That is, the bottom side of the flow projections are not directly extended downward from the bottom surface is formed in the "open" groove type between the flow projections and the bottom surface, the side of the flow projection is extended downward from the lower end of the inner diameter of the flow connection forming a closed loop In addition, the bottom surface extends in the horizontal direction from the lower end of the outer diameter of the flow connecting portion, the flow projection is a state capable of independently flowing to the bottom via the flow connecting portion.

Therefore, according to the load applied to the bottom of the recess groove of the upper surface of the lower sole, which may also be referred to as the upper surface of the flow protrusion, the flow protrusion protrudes further downward from the bottom of the lower sole, and thus may be more closely attached to the bottom or pushed toward the upper surface of the lower sole. It becomes a state.

The upper sole has a structure in which a plurality of through holes corresponding to the respective recessed groove positions of the lower sole are formed therethrough. The upper sole absorbs the impact that is not absorbed by the lower sole while being laminated on the upper bottom of the sole, and penetrates the through holes according to the applied load. It is a function that allows an insertion protrusion to move elastically.

The insertion protrusion is composed of a plate-shaped locking portion stacked on the upper surface of the upper sole and a protrusion projecting downward from the center of the bottom surface of the locking portion, and the protrusion is cut along the axial direction to be separated into at least two or more portions and at the same time on the outer peripheral surface thereof. It is a structure in which teeth are formed so that a number of mountains and valleys are formed.

The protrusion is inserted into the recessed groove formed in the upper surface of the lower sole by passing through the through hole of the upper sole, and the lower end of the protrusion presses the bottom of the recessed groove according to the compressive load applied to the upper surface of the locking portion to allow the flow of the bottom of the lower sole. Protruding the projections further downward to increase the adhesion between the bottom and the flow projections.

At this time, the lower end of the protrusion of the insertion protrusion is in close contact with the bottom surface of the recess groove, and the upper end is formed in the state extending from the bottom of the locking portion, when the load is applied to the protrusion in the state in which the flow protrusion of the lower sole is protruded to the maximum, The two or more divided protrusions, the upper and lower ends respectively fixed to the engaging portion and the bottom of the recess groove serve as a functioning point of force, and as a result, the middle portion between the upper and lower ends elastically opens to absorb the compressive load. do.

That is, as the upper sole is compressed by the compressive load applied to the locking portion, the protrusion descends and presses the bottom of the recessed groove of the lower sole, so that the flow projection of the bottom of the lower sole is further protruded downward, and the lower end is in close contact with the bottom of the recessed groove. The middle portion in the height direction of the protrusion is opened in the horizontal direction, and the compressive load is absorbed as the middle portion of the protrusion is further opened from the point when the flow protrusion protrudes downward.

The outer circumferential surface of the projection is in close contact with the inner circumferential surface of the through-hole of the upper sole, and the teeth formed on the outer circumferential surface of the projection are inclined by the outer circumferential surface like an arrowhead, and the inclination direction is directed from the outer circumferential surface of the projection toward the outside as shown by the downward arrow The upwardly inclined bar easily protrudes through the through hole of the upper sole, but it is difficult to penetrate the through hole by the teeth of the outer peripheral surface.

The shoe bottom member of the present invention configured as described above is, for example, rubber, urethane, EVA (EVA), such as flexible yet elastic, that is, the upper and lower soles made of a material excellent in shape resilience, the shock absorbency The shock absorbing property and the adhesion to the floor are improved by the elastic force of the insertion protrusion made of nylon or plastic, which is harder than the sole.

The spike member extends the service life of the rear end of the severely worn outsole, and at the same time, a spike member having an appropriate shape can be applied according to the use of the shoe. If you combine it can also be used for winter hiking boots.

In other words, the front part of the lower sole is more tightly adhered to the floor while absorbing the shock, while the front part of the lower sole can be detachably coupled to the spike member of the appropriate height or structure to stably take a posture during exercise such as golf. In addition, it is possible to share the role of preventing slipping during winter hiking.

The details of the purpose and technical constitution of the present invention and the resulting effects thereof will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

FIG. 2 is a cross-sectional view of the first embodiment shoe bottom member of the present invention, and FIG. 3 is an exploded perspective view of the first embodiment shoe bottom member of the present invention.

As shown the shoe bottom member of the present invention,

A plurality of recessed grooves G and flow projections E are formed on the upper and lower surfaces S _U and the lower surface S _L 1: 1 at the front of the arch of the foot, respectively, and the bottom surface S _L. A lower sole 21 in which a plurality of first coupling members F such as nuts or bolts exposed to the outside are embedded in the rear portion;

An upper sole 22 stacked on an upper surface S _U of the lower sole 21 and having a plurality of through holes H formed therethrough;

A plurality of insertion protrusions 23 penetrating through the through holes H of the upper sole 22 and then inserted into the recessed grooves G of the lower sole 21;

A plurality of spikes are provided with a second coupling member (F '), such as a bolt or a nut, which is detachably coupled to each of the first coupling members (F) exposed to the rear surface (S _L ) of the rear sole (21). Member 24 or the like. Reference numeral "B" in FIG. 2 is "shoe body".

At this time, a plurality of fixing protrusions E 'are formed on the entire bottom surface of the lower sole 21, while the fixing protrusions E' move together with the bottom surface S _L , while the flow protrusions E are The structure may move together with the bottom surface S _L of the lower sole 21, but may move independently. The upper outer circumferential surface of the flow projection E and the bottom surface S _L of the lower sole 21 are “∩” shaped cross sections. Is connected by the flow connection portion (R) of, the flow connection portion (R) is a structure forming a closed loop like a ring around its outer circumference around the flow projection (E).

That is, between the bottom surface S _L of the lower sole 21 and the outer circumferential surface of the flow projection E, there is a moat-shaped groove which is made around the old castle.

And, the upper surface of the flow projection (E) becomes the bottom surface of the concave groove (E), the upper surface (S _U ) of the lower sole 21 in contact with the rim of the concave groove (E) ring-shaped by the flow connection (R) The protrusion is formed.

In addition, the insertion protrusion 23, as shown in Figure 4, the plate-like engaging portion 23A that the bottom surface is in close contact with the upper surface of the upper sole 23; It protrudes downward from the center of the bottom face of the locking portion 23A, is cut along the axial direction and is composed of at least two small protrusions 23B1, and includes a protrusion 23B having a plurality of teeth T protruding from the outer circumferential surface thereof. .

At this time, it is preferable that the outer diameter of the protrusion 23B is not smaller than the inner diameter of the through hole H of the upper sole 22, and the bottom surface S _L ′ of the tooth T is inclined upward toward the outside. This is because the protrusion 23B can easily penetrate the through hole H, but the protrusion 23B penetrating the through hole H does not easily escape from the through hole H.

That is, when the upper sole 22 is pressed, the length of penetration of the protrusion 23B protruding to the bottom thereof becomes long, and the upper sole 22 pushes the flow protrusion E of the lower sole 21 and returns to the original position. This is to prevent the projection 23B from escaping from the through hole H more than necessary due to the elastic force of), and to allow the return movement of the projection 23B to be gradually performed.

In addition, the cross-sectional area of the protrusion 23B is made relatively smaller than the cross-sectional area of the recessed groove G or the flow protrusion E so as to minimize load distribution applied to the bottom of the recessed groove G by the protrusion 23B. It is more effective in the downward protrusion movement of the flow projection (E).

In addition, the protrusion 23B is cut in two or more parts, while the lower end is in close contact with the bottom of the recessed groove G, even though the flow protrusion E is pushed to the bottom side as much as the downward load is applied to the insertion protrusion. 25 or the flow connection part R may be damaged. In order to prevent this, that is, the middle part of the protrusion 23B cut into two or more parts may be elastically opened with respect to each other and absorb excessive downward load. To make it work.

At this time, the lengths of the plurality of small protrusions 23B1 may be all the same, but the lengths of the small protrusions 23B1 may be different so that each of the small protrusions 23B1 is elastically deformed in sequence and then elastically deformed together. It may be.

In addition, the spike member 24 coupled to the rear bottom surface S _L of the lower sole 21 may have a pin shape (Fig. 4-A) and a tooth shape (Fig. 4-B) as shown in Fig. 5. It can be made in various shapes according to the use of shoes, such as the general projection type (Fig. 4-C), for example, golf shoes, pin or toothed type, winter climbing shoes, toothed type, general A general protrusion type may be applied to a mountain climbing shoe or a general shoe, and as the material, a metal, a synthetic resin, or a metal and a synthetic resin may be mixed, and may have various shapes according to a use.

However, if necessary, the recessed groove G and the flow protrusion E may also be provided in the rear portion of the lower sole 21 without using the spike member 24.

In addition, the bottom surface of the locking portion 23A of the insertion protrusion 23 may be firmly fixed to the upper surface of the upper sole 22 so that the insertion protrusion 23 does not completely exit from the through hole H of the upper sole 22. When the insertion protrusion 23 is simply penetrated through the through hole H, the protrusion 23B may move upward while the locking portion 23A may protrude from the upper surface of the upper sole 22, if necessary. As shown in FIG. 6, a separate insole 25 may be stacked on the upper surface of the upper sole 22 including the insertion protrusion 23.

At this time, the movement of the inserting protrusions 23 should be adjusted individually or as possible, or if the inserting protrusions 23 are different, but the material and thickness of the insole 25 should be adjusted according to whether they move together. do.

In addition, the engaging portion seating groove (not shown in the drawing) on the upper surface of the upper sole 22 around the through hole (H) so that the upper surface of the upper sole 22 and the upper surface of the engaging portion 23A of the insertion protrusion 23 form the same plane. It is also preferable to have a).

As described above, the shoe bottom member of the present invention, since the external shock is sequentially absorbed by the upper and lower soles and the insertion projections, the shock absorption efficiency is improved, and compared to the sole, a plurality of made of a relatively hard material As the protrusions move independently, the corresponding flow protrusions can be more efficiently projected downwards according to the load applied to the sole, and the adhesion with the bottom is improved.In addition, the protrusions of the insertion protrusions are separated into a plurality of insertion protrusions, flow protrusions, There is an advantage in that damage to the flow connection is prevented.

And, by detachably connecting the spike member to the bottom rear end of the bottom sole which is worn out the most, the service life of the shoe can be extended, by combining spike members of various shapes and structures, if necessary, winter hiking shoes, There is an advantage that can be applied to golf shoes.
