DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 to 14, a safety boot 100 according to an embodiment of the present invention includes an outsole 110 contacting a ground surface, an insole 140 and an outsole 140 provided on the outsole 110, 110 to cover the foot.

The outsole 110 is in contact with the ground, and is manufactured by a nested pitcher 200 including the forefoot, middle, and rear feet. The outsole 110 is made of a material having excellent frictional properties, such as rubber or silicone, and is formed by a mold. The bottom surface contacting with the ground surface is formed with irregularities to increase slip resistance.

The outsole 110 is formed by the nostril fin 200 and has an enlarged portion corresponding to a large toe shape and extending outward in comparison with a shape formed by the general last portion, 115 are provided.

Here, the nest palette 200 is manufactured in the shape most similar to the human foot shape, and particularly, the toe and the sole portion are formed almost as they are, and the material thereof can be selected from wood, synthetic resin material, metal material, It is also possible to manufacture by selecting a material. This nested palette 200 is a tool used to optimize the gripping feeling of the safety shoes 100.

4 to 7, the nested pitcher 200 is divided into a forefoot part, a middle part and a rear part, and the forefoot part is connected to the toe part and the bones of the toe part. The midfoot is the central part of the foot, the arch-shaped structure for forming the middle part of the foot, and the hindfoot for shaping the calcaneus part of the heel bone.

A first tongue portion 210 protruding in a shape corresponding to the thumb toe shape of the human body is provided on one side of the forefoot tip of the nostril tail 200, And protrudes upward in a rounded manner. 4 and 9, an extension protrusion 220 protrudes outwardly from the first toe side surface of the first tongue 210 in order to form the extension 115 of the outsole 110.

The first tongue 210 can minimize the pressure feeling applied to the big toe while increasing the fitting force and prevent the disease such as the atypical hallucination in which the big toe curves outward in the long term. In addition, the enlarged portion 115 can be formed on the outsole 110 by the extended protrusion 220, so that it is possible to prevent the thumb toe from being pushed toward the other toe due to the external pressure, thereby maximizing the wearing comfort.

The concave / convex portions 230 may be rounded and curved in a zigzag shape so as to correspond to the respective protruding shapes of the second to fifth toes of the toes of the human body at the forefoot portion 230 of the nostril tail 200, Is connected to the first tongue portion (210). As a result of this configuration, not only the big toe but also the uneven shape space for fixing all the fifth toes corresponding to the second toe can be formed in the inner side of the safety shoes 100, have.

As shown in FIG. 4, an arch-shaped second tongue 240 protruding outwardly may be formed on the inner side of the crotch of the nest palette 200, It is a shape corresponding to the bone, that is, the ball of foot, protruding outward from the inner side of the part. The second stone tongue 240 prevents the foot from being deformed due to football pressure in the long term without causing the foot to feel comfortable and painful even if a person with a wide foot is not pressing the football.

As shown in FIG. 5, in the bottom surface of the bottom portion of the nostril portion 200, a first valley portion having a shape corresponding to a valley having an arch-like groove at the bottom of the body of the human body and round- (250) may be formed. Since the midsole 120 protrudes upward in a manner corresponding to the first bottom portion 250 by the first bottom portion 250, the insole 140 is not only raised but also seated on the midsole 120, The shape of the midsole 120 is the same as each other, so that the feeling of fitting can be doubled.

Referring to FIG. 5, a nest palette 200 is applied to an upper portion 170 of the nest palette 200. The nest palette 200 has a shape corresponding to a bone protruding upwards in an arch shape at a foot portion of a human body, A third tongue 260 protruding upward is formed. Since the space of the inner surface of the safety shoes 100 protruded in the shape corresponding to the third tongue 260 is formed by the third tongue 260, it is not pressed against the foot during the ignition, and furthermore, Even if the straps are tightened, the fitting force is uniformly tightened, and the fitting force is increased.

In addition, not only the bone corresponding to the first bone part 250 but also various forms of bone between the forefoot and the middle part are formed on the sole of the human body, and a shape corresponding to the bone of the sole is formed on the bottom surface of the nostu palette 200 Bone is formed. That is, as shown in FIG. 6, between the forefoot portion and the midway portion of the human body at the boundary between the forefoot portion and the crotch portion of the nostril track 200, The second trough portion 270 is formed. In the second trough portion 270, five tongues of the sole are connected to each other. The tongue portion is shaped like a tongue with respect to the sole. That is, the tongue is recessed in the lateral direction with respect to the foot. According to the second trough portion 270, since the corresponding portion of the second trough portion 270 of the midsole 120 is extended in the lateral direction, the entire toe can be fixed, thereby improving the fitting feeling.

As shown in FIG. 7, between the forefoot and the midfoot of the nostril track 200, between the third toe and the fourth metatarsal of the fourth toe of the human body, A valley 280 is formed. As described above, the metatarsal and toe bones of the toe and the ankle joints of the foot are connected to the five toe bones, so each of them is composed of five, and the part connected to the big toe bones is the first metatarsal bone And a portion connected to the young toe bone is referred to as a fifth metatarsus. A groove is formed between the first to third metatarsals and the third and fourth toes corresponding to the space between the fourth and fifth metatarses at the sole. ) Corresponds to the groove.

The third trough portion 280 has the second trough portion 270 formed in the transverse direction and the front portion of the midsole 120 is raised in a shape corresponding to the second and third trough portions 280, So that it can be fixed more precisely and stably so that the fitting feeling can be doubled.

As described above, the nest palette 200 is applied to manufacture the stabilization 100, so that the grip feeling can be optimized.

At the tip of the outsole 110, an external toe cap 130 is integrally formed. The top of the external toe cap 130 has a peak at the top of the toe, and a tapered shape toward the bottom of the toe.

As shown in FIG. 12, the outer toe cap 130 is formed such that its outer surface protrudes upward so as to improve adhesion with the front of the upper part 170. The external shape of the external toe cap 130 may be formed as a peak shape protruding upward, or a variety of designs such as a toe shape may be applied.

Since the height of the external toe cap 130 has a peak at the large toe portion, the toe can be protected from external impact.

The insole 140 includes a front support portion 162, a middle support portion 164 and a rear foot support portion 166 for supporting the entire body (A), middle body (B), and rear portion (C) of the human body. As shown in FIGS. 10 and 11, the insole 140 forms a single layer by combining a plurality of materials having different hardnesses according to positions.

This is because the human foot is divided into a full body (A) including the toe, a heel (C) including the heel, and a middle body (B) located between the fore (A) and the rear (C) When grounding on the ground, the pressure due to the load is distributed differently according to the position of the sole.

The pressure distribution in the general case is that the first region 1 in which a relatively large pressure acts on the heel portion of the rear leg C and the forefoot portion of the middle leg B is distributed and the toes of the legs A are grounded A second zone 2 in which a pressure relatively lower than the pressure of the first zone 1 is applied to the periphery of the first zone 1, And a third zone (3) where the lowest pressure is applied to the remaining part except for the first and second zones (1,2).

 10 and 11, the insole 140 is provided with a base plate 150 having an outline shape of the sole of the sole. Inside the base plate 150, a forefoot hole 151, a middle hole 152, And a rear foot hole 153. These holes 151, 152 and 153 are positions corresponding to the full length (A), middle length (B) and rear length (C) of the sole.

Of course, any one of the forefoot hole 151 and the forefoot hole 153, or two arbitrarily selected ones, may not be formed, but may be formed integrally with the base plate 150 itself. That is, only one of the forefoot hole 151, the middle hole 152, and the forefoot hole 153 may be formed, or only two arbitrarily selected ones may be formed, and such modification is also within the scope of the present invention.

The base plate 150 thus manufactured may be in a shape corresponding to the third zone 3 in which the pressure is relatively small and may be a material having a high hardness in consideration of the lowest pressure, . When the hardness of the base plate 150 is in the range of 60 to 80, preferably 68 to 76, based on the hardness of the ASKER C type (ASKER C TYPE), the material is not limited and examples of the material include ethylene vinyl acetate (EVA) Vinyl Acetate) expanded molded article, and polyurethane (PU) expanded molded article.

The inner plate 160 is formed in a shape corresponding to each of the holes 151, 152, and 153 formed in the base plate 150. The inner plate 160 is assembled so as to form a single layer of the insole 140 by filling any one of the holes 151, 152 and 153 with the front supporting portion 162, the middle supporting portion 164, And a foot support portion 166. [0035]

The inner plate 160 is made of a material having a lower hardness than the base plate 150 because a relatively large pressure is applied to the inner plate 160 at a position higher than the position of the base plate 150. If the hardness of the inner plate 160 is in the range of 20 to 40, preferably 28 to 36, based on the hardness of the ASKER C type (ASKER C TYPE), the material is not limited and examples of the material include ethylene vinyl acetate (EVA: Ethylene -Vinyl Acetate) expanded molded article, and a polyurethane (PU) expanded molded article.

Since the hardness of the base plate 150 and the inner plate 160 are different from each other, it is effective in buffering action by the inner plate 160 having a hardness corresponding to the portion where the pressure greatly acts, Since the insole 140, in which the base plate 150 and the inner plate 160 are combined, forms a single layer, a layer is not formed as compared with a layer attached to the base plate 150, so that there is no sense of heterogeneity and a feeling of fit is improved.

On the other hand, a material having a lower hardness may be separately disposed inside the inner plate 160. A heel hole 167 is formed in the rear foot portion 166 of the inner plate 160 and a first plate 167a different in hardness from the inner plate 160 is inserted into the heel hole 167, The forefoot hole 165 is pierced in the middle support portion 164 of the inner plate 160 and the second plate 165a having different hardness from the inner plate 160 is inserted into the forefoot hole 165. [

The first and second plates 167a and 165a have a hardness lower than that of the inner plate 160 and the height of the first and second plates 167a and 165a may be higher than the height of the inner plate 160.

Since the first and second plates 167a and 165a are relatively less rigid than the base plate 150 or the inner plate 160, it is difficult to measure the first and second plates 167a and 165a at about the ASKER C type, (Ethylene-vinyl acetate) (EVA) foamed molded article, air-permeable polyurethane (PU), or the like, as an example of the material, Expanded molded articles.

At this time, air holes are selectively formed in the first and second plates 167a and 165a in the vertical direction so that air flows in the up and down direction of the insole 140 to prevent sweating, Can be reduced.

A metatarsophalangeal support portion 154 raised upward in an arch shape corresponding to the valleys formed on the middle leg B of the sole is formed on the side of the middle portion B of the base plate 150, The metatarsophalangeal support portion 154 supports the valgus (B) valley portion of the sole, so that the fitting feeling can be improved.

Likewise, in the base plate 150, between the forefoot hole 151 and the middle hole 152, the bone formed on the fore part of the soles A, that is, the bone formed on the part between the toe and the middle part B, The fore-and-aft part 155 is formed and the fore-and-aft bone is supported by the entirely-oval supporting part 155 having a greater hardness.

The upper 170 is coupled with the outsole 110 to cover the foot, and the outer leather is trimmed to fit the design, the leather is cut into a three-dimensional shape by pressing the leather, do. Inside the upper part 170, there is provided an inner skin 175 which is in contact with the foot.

At this time, the upper part of the upper part 170 is provided with a rigid part 180 for protecting the toe from external impact. The rigid portion 180 includes a toe cap 182 covering the toe and a toe plate 184 supporting the toe gap. As shown in FIG. 12, the toe cap 182 has a size covering the forefoot portion of the human body. The toe cap 182 is formed to be inclined downward to the toe side with respect to the big toe, and the forefoot portion of the foot can be inserted by opening the lower and rear sides . The toe cap plate 184 supports the toe cap 182, and is formed in a U shape.

A midsole 120 is provided between the outsole 110 and the insole 140 and the toe plate 184 is seated in the seating groove 125 provided in the midsole 120 and is fixed by adhesion.

The toe cap 182 has an inwardly bent flange 183 at its lower edge and the flange 183 is seated on the top surface of the toe plate 184 and joined by an adhesive.

The protection portion 190 is provided inside the upper portion 170 as shown in FIG. 13 to protect the foot from an external impact. That is, the toe cap 182 protects the toe from external impacts due to rigidity, while protecting portion 190 protects the foot from external impact while keeping the hardness smooth.

It is preferable that the protection unit 190 is provided in 70% or more of the important parts outside the safety shoes 100.

The protection portion 190 is made of a silicon pad formed by silicon applied to the inner surface of the upper portion 170. That is, the protective portion 190 is provided between the upper portion 170 and the inner portion 175, and is made of silicon, so that the hardness can be maintained smoothly, and thus, the protective portion 190 can be active.

The protective portion 190 is formed by applying silicone to the inner surface of the upper portion 170, which is formed in a three-dimensional shape by pressing a leather cut material with a metal mold, followed by drying. Silicone is a complementary material that prevents the three-dimensional shape of the upper portion 170 from being worn for a long period of time and being embedded in an external impact.

The protective portion 190 may be divided into a plurality of portions to disperse the impact strength. As shown in FIG. 14, the protection unit 190 is subdivided into a horizontal bar 195 and a vertical bar 195 to protect the feet by dispersing the impact strength upon impact.

As described above, according to the safeguard according to the embodiment of the present invention, it is possible to optimize the gripping feeling by being manufactured by the nostalgic fit, and to prevent the leaning of the big toe, thereby providing the comfort of the foot. In addition, it is possible to appropriately cope with different pressures depending on the position of the sole by the different insole by the different hardness, so that pain and fatigue can be solved when walking for a long time, In particular, since the hardness can be maintained smoothly by the protective part made of a silicon pad, the inconvenience can be solved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
