On the other hand, the conventional boots are formed such that the opening is substantially wider than the calf circumference of the human body so that the worker can easily wear and demold. As a result, there is a problem that water or foreign matter permeates at intervals spaced between the opening and the calf, resulting in contamination of the inside of the boots and foot of the worker, and poor fit. Furthermore, there has been a problem in that a safety accident such as a scratch on the operator's base caused by the foreign matter occurs.

Accordingly, in the prior art, a boot having a tightening part for closing the opening has been partially disclosed. However, if the fastening portion can not be firmly fastened, the knot can not be loosened to substantially seal the opening portion, and the elongated string interferes with the walking of the worker. On the other hand, when the tightening band portion is excessively tightened, it is difficult to remove the bandage after use, and the excessive calf portion is pressed and the operator feels uncomfortable.

Further, since the calf muscles of the human body are formed in a convex shape, the narrow width of the tightening bands flows along the calf profile narrowed downward in a state of being wrapped around the convex portions of the calf muscles to lower the fixing force and the sealing force there was.

Further, when the size of the boot is larger than the foot size of the operator, it is inconvenient to walk and cause a safety accident due to the fall. In addition, when a plurality of boots corresponding to the foot sizes of the operators are provided, it is difficult to store and manage the boots and the economical efficiency is lowered.

As shown in FIGS. 1 to 4, the boots 100 according to the preferred embodiment of the present invention preferably include the sole 10, the skin 20, and the elastic fixing unit 30.

The sole 10 is provided to support the sole of the human body and has an area corresponding to an outer profile of the sole, and has a seating surface 12 to which the sole is closely contacted, and a bottom surface 11 which is in close contact with the ground. Are formed to have a predetermined thickness. The sole 10 is preferably made of a synthetic resin material having a predetermined cushioning feeling so as to cushion impact against the ground during walking while protecting the sole from contaminants remaining on the surface of the ground.

At this time, the sole 10 has a rigidity to support the sole without being excessively squeezed against the load of the human body, and a semi-rigid body having a predetermined elasticity corresponding to the curved profile of the sole, As shown in FIG. Accordingly, even when the user wears the boots or wears the boots 100 for a long time, the user can comfortably support the sole, thereby minimizing fatigue. Further, the seating surface 12 may be provided with a bent portion corresponding to the arch of the central portion of the sole, so that the wearing comfort of the wearer may be further improved.

It is preferable that the cape skin 20 continuously extending upward from the shoe sole 10 is provided. The cap skin 20 includes a foot receiving portion 21 and a calf receiving portion 22 and an opening 23 is formed at the upper end of the calf receiving portion 22. [ At this time, the foot receiving portion 21 and the calf receiving portion 22 may be substantially integrally connected to each other at a portion covering the ankle outer side of the human body.

In detail, the foot receiving portion 21 is provided in a shape corresponding to the outer shape of the foot p so as to receive the heel from the toe of the human body. The calf receiving portion 22 extending upwardly from the foot accommodating portion 21 integrally extends to a length covering the legs of the human body, particularly the calf c extending from the ankle to the upper side.

The shoe sole 10 and the cape skin 20 may be formed of a synthetic resin material such as natural rubber, synthetic rubber, polyvinyl chloride (PVC), ethylene vinyl acetate copolymer (EVA), or a mixture thereof. The molten material may be injected into a mold having a cavity corresponding to the shape of the boot 100 to be injection-molded. At this time, the cavity shape of the mold may be provided in a state where the sole 10 and the cape 20 are integrally connected to each other. In some cases, the cap 20 and the cap 20 may be separated from each other Or may be integrally formed by heat-sealing.

At this time, the calf receiving portion 22 is formed as a semi-rigid body having both elasticity to be variable according to the movement of the wearer, and rigidity that can be erected by the magnetic force while protecting the wearer's undergarment from external impact .

As a result, the wearer is deformed with a certain flexibility in accordance with the walking and the movement of the wearer, thereby remarkably improving the feeling of wearing, while preventing the wearer from being polluted or accidentally caused by moisture or falling objects. In addition, the boots 100 can be compactly stored in a standing state without collapsing even when stored, and the connecting portion between the foot receiving portion 21 and the calf receiving portion 22 can be torn or broken by collapse .

At this time, it is also possible to adjust the mixing ratio of the synthetic resin or synthetic rubber material or to further insert a reinforcing member into the calf receiving portion 22 so that the strength of the calf receiving portion 22 is improved.

On the other hand, the boots 100 are manufactured to have a receiving space larger than the volume of the feet p and calves c of the human body, so as to be able to be easily worn and demounted by the wearer and to reach the lower end of the wearer . A space s is formed between the outer surface of the calf c of the human body and the inner surface of the calf receiving portion 22 while the boots 100 are worn and the space s is formed through the opening 23, s) may be infiltrated with moisture or foreign matter. This can contaminate the wearer's undergarments and undergarments and can lead to serious safety hazards if the dangerous material is infiltrated.

Accordingly, the present invention provides a configuration for solving such a problem.

In the opening 23 formed in the upper end of the calf receiving portion 22 to selectively seal the space s between the outer surface of the calf c of the human body and the inner surface of the calf receiving portion 22, (30) is preferably provided.

The elastic fixing part 30 is provided to surround the hollow part 35 communicating with the opening 23 and the edge of the one end 30a corresponds to the diameter of the rim 23a of the opening 23 So as to be elastically deformed. The inner surface of the other end 30b, which is formed to be narrower than the opening 23 due to the elastic force, is elastically adhered in correspondence with the outer surface profile of the calf c of the human body. At this time, it is preferable that the outer surface of the calf (c) of the human body is understood to be substantially the lower end surrounding the outer surface of the calf (c), that is, the outer side of the crotch crotch. In other words, the inner surface of the elastic fixing part 30 may be directly and elastically contacted to the outer surface of the calf c of the human body, but it may be provided on the outer side of the lower leg crotch part, It is preferable to understand that it is in close contact.

Accordingly, since the outer surface of the calf c of the human body is elastically contacted by the elastic force of the elastic fixing part 30 while the boots 100 are worn, the space s can be sealed. Accordingly, since the infiltration of moisture and foreign matter is prevented, the warm air layer heated by the body temperature is kept in a sealed state while the safety of the wearer is secured, so that the warmth of the base can be remarkably improved.

At this time, the resilient fixing portion 30 is elastically held between the one end portion 30a and the other end portion 30b, so that the adjacent outer surface side cn of the convexly protruded profile of the calf c is elastically in contact with the outer surface side. Are preferably extended to a predetermined width.

Specifically, the calf c is convexly formed on one side of the rear side between the knee and the ankle by the calf muscles, and becomes gradually thinner toward the ankle side. At this time, the elastic fixing part 30 is in surface contact with the convex part of the calf c and the outer side cn adjacent to the upper and lower sides thereof and thinner than the convex part. That is, since the elastic fixing part 30 is elastically deformed corresponding to the profile of the calf c to widen the surface contact area, the stable close contact state can be maintained.

Furthermore, it is preferable that the predetermined width is set to be 5 to 10 cm wide from the opening 23. In detail, when the resilient fixing portion 30 is extended to a width of less than 5 cm, the outer surface profile of the calf c and the inner surface of the resilient fixing portion 30 are narrowed in area. As a result, the area where the elastic fixing part 30 is in close contact with the outer surface of the calf c is narrowed and the fixing force is lowered, and the pressing force of the elastic fixing part 30 is concentrated on the narrow part, Can be weighted.

On the other hand, if the elastic fixing part 30 is extended to a width greater than 10 cm, the surface area contact with the outer surface of the calf c is widened, but unnecessary cost is increased and the economical efficiency is lowered. Therefore, it is preferable that the elastic fixing part 30 is extended in a width of 5 to 10 cm, which is sufficient in surface contact with the outer surface of the calf c to secure its economical efficiency.

It is preferable that the elastic fixing part 30 is formed of a woven ring-shaped elastic band including a weft formed of synthetic fibers having stretchability.

In detail, the elastic band may be formed of a woven synthetic fabric woven by crossing a weft and a warp, and the weft may be formed of a synthetic fiber yarn having stretchability. As a result, the elastic force is elastically stretched corresponding to the convexly protruding profile of the calf c, and then stably comes in close contact with the rest of the calf c as the restoring force is applied to the outer surface of the calf c, It can be sealed.

At this time, the warp yarns may be made of synthetic fibers having relatively less elasticity than the weft yarns. Accordingly, even if the boots 100 are lifted or pulled when worn, it is possible to prevent excessive extension in the vertical direction of the elastic fixing part 30, so that durability can be remarkably improved.

That is, the elastic fixing part 30 is elastically deformed in its diameter according to the profile of the outer surface of the calf c, while the width between the one end 30a and the other end 30b is substantially maintained, Since the band is provided, the feeling of fit and durability can be improved together. Of course, in some cases, the weft yarns and the warp yarns may be woven with synthetic fibers having elasticity, and such modifications fall within the scope of the present invention.

At this time, the one end 30a of the elastic fixing part 30 is fixed in the form of wrapping the outer surface of the rim 23a of the opening 23, and is preferably sewn on the rim 23a of the opening 23 Do. The outer surface of the one end portion 30a of the elastic fixing portion 30 and the outer surface of the opening portion 23a of the elastic fixing portion 30 are formed so as to improve the stitching force between the one end portion 30a of the elastic fixing portion 30 and the rim 23a of the opening portion 23, It is preferable that a reinforcing band portion (not shown) is further provided on the inner surface of the rim 23a. That is, as the one end 30a of the elastic fixing part 30, the rim of the opening 23, and the reinforcing band part (not shown) are sewn together, the mutual fixing force can be improved. In addition, durability of the rim 23a of the opening 23 on which the sewing line is formed and the end 30a of the elastic fixing part 30 can be remarkably improved.

It is preferable that a first coating portion 31 having a predetermined design pattern is formed on the inner surface of the elastic fixing portion 30. In this case, it is preferable that the predetermined design pattern includes predetermined colors together with predetermined patterns.

Here, the first coating part 31 is preferably made of a material having an inner slippery property and a cushion feeling together with a predetermined elastic force such as polyurethane, nitrile-butadiene rubber (NBR) or latex material.

Accordingly, when the elastic fixing part 30 is elastically deformed, the first coating part 31 can be elastically deformed together, and the pressing force elastically in surface contact along the outer surface profile of the calf c is further reinforced It is possible to maintain firm close contact and a closed state.

In addition, since the above-mentioned materials have a high frictional force due to elasticity, the elastic fixing part 30 is prevented from slipping while being in close contact with the outer surface of the calf c, so that the sealing performance can be further improved. In addition, since the inner surface of the elastic fixing part 30 is coated so as to have a predetermined cushioning feeling, it is possible to provide an elastic force that can be substantially fixedly fixed to the outer surface of the calf c while preventing excessive compression, Can be improved.

At this time, the inner coating surface of the first coating part 31 may be formed with a ring-shaped protrusion 33 protruding in multiple steps along the width direction. Specifically, the contact protrusions 33 may be formed on the inner circumferential surface of the elastic fixing portion 30 so as to protrude toward the center of the hollow portion 35 and surround the outer surface profile of the calf c.

In addition, since at least one or more ends are formed in the width direction of the elastic fixing part 30, the adhesion with the outer surface of the calf c and the slip-preventing effect can be further improved. At this time, the contact protrusions 33 may be integrally formed so as to protrude toward the hollow portion 35 at the time of manufacturing the first coating portion 31. Of course, the protrusions may be integrally formed with the elastic band constituting the elastic fixing part 30, and the inner surface of the elastic fixing part formed with the protrusions may be coated with the first coating part 31 have.

In addition, it is preferable that a second coating portion 32 is formed on the outer surface of the elastic fixing portion 30. At this time, the second coating portion 32 may be formed in a design pattern including predetermined colors together with predetermined patterns, and a pattern different from the first coating portion 31 may be formed.

Here, the second coating part 32 may be coated with the same material as the first coating part 31, and may be elastically deformed together with the elastic fixing part 30. As the inner surface and the outer surface of the elastic fixing part 30 are coated with the first coating part 31 and the second coating part 32, the elastic band woven with synthetic fiber yarn is waterproof, It is possible to substantially prevent impregnation.

A folding boundary is formed along the border between the one end 30a of the elastic fixing part 30 and the opening 23 so that the inner surface of the elastic fixing part 30 is selectively exposed to the outside by the folding operation. (34) is preferably formed.

The folding boundary portion 34 is formed in a manner that the one end portion 30a of the elastic fixing portion 30, the rim 23a of the opening portion 23 and the reinforcing band portion (not shown) It is desirable to understand it as an adjacent border area. That is, the folding boundary portion 34 is supported on the sewing area boundary by the difference in thickness between the sewing area and the edge area adjacent thereto, so that the folding operation can be easily performed.

The first coating part 31 is in surface contact with the outer surface of the calf c of the human body and elastically deformed according to the convex outer surface profile of the calf c, . Accordingly, the space s between the inner surface of the calf receiving portion 22 and the outer surface of the calf c of the human body can be stably watertightly sealed.

Further, the resilient fixing portion 30 is formed to have a predetermined width, and is substantially fixed to the convex profile of the calf c and to the adjacent outer side surface cn. Accordingly, even if the inner space of the boots 100 is formed larger than the volume of the feet p and calves c of the human body, the rocking or peeling at the time of walking can be minimized. As a result, the wearer can easily walk and the safety is remarkably improved, and the boots 100 can be used universally regardless of the different footwear sizes for each wearer, thereby remarkably improving the economical efficiency.

Meanwhile, when the first coating portion 31 is turned upside down on the folded boundary portion 34 so as to be exposed to the outside, the second coating portion 32 is brought into close contact with the outer surface of the calf receiving portion 22.

Accordingly, since the elastic fixing part 30 is formed to cover the outside of the opening 23 of the cape 20, the thickness of the opening 23 is reinforced and the durability can be remarkably improved. In addition, since the space s between the inner surface of the calf receiving portion 22 and the outer surface of the calf c of the human body is opened, it is possible to easily wear or dislodge the wearer. Furthermore, since the space s is opened at a place where cooling or ventilation is required, the air circulation is smooth even to the inside of the boots 100, so that the feeling of comfort can be remarkably improved.

Since the first coating part 31 and the second coating part 32 are formed in patterns different from each other in design, when the elastic fixing part 30 is folded, the boots 100 of different designs are used Can be provided.

At least one of the inner surface and the outer surface of the one end 30a and the other end 30b of the elastic fixing part 30 may be coated on the first coating part 31 and the second coating part 32, A pattern of a band shape different from that of the design may be further formed. Accordingly, since the elastic fixing part 30 is folded or unfolded while wearing the boots 100, patterns of various designs can be harmonized to provide a unique aesthetics, so that the satisfaction of the wearer can be further improved .

In addition, since the outer surface of the cape skin 20 is formed in a pattern different from that of the coating portions 31 and 32, various appearance can be expressed by one boot 100, . In addition, since the unfolded or folded state of the elastic fixing part 30 can easily be confirmed by visually checking a predetermined design pattern displayed to the outside, the wearing convenience can be further improved.

On the other hand, acupressure projection 12a is provided on the seating surface 12 of the shoe sole 10, and a slippery recess 11a is formed on the bottom surface 11 of the shoe sole. Accordingly, even if the wearer walks and operates by wearing the boots 100 for a long time, the acupressure projection 12a smoothly presses the sole of the human body, thereby minimizing fatigue. Further, since the slip-proof concave / convex portion 11a is formed on the bottom surface 11, safety of the wearer can be further improved by preventing slippage of the wearer even in a slippery work environment.

In addition, reinforcing overhangs 24a, 24b, and 24c for protecting the outer peripheral portion of the human body may be formed on the outer surface of the skin 20. [ Here, the outer peripheral portion of the human body is preferably understood as a toe, a peach bone, and a heel, and may include a foot that can be impacted by a falling object.

In detail, the reinforcing overhang portions 24a, 24b, and 24c may be thicker than the skin 20, or a reinforcing member may be inserted and protected therein. This makes it possible to protect the outer peripheral portion of the human body from external shocks. Further, since the reinforcing overhang portion is also provided at the portion surrounding the ankle, the occurrence of cracks in the skin 20 due to the movement of the ankle is minimized, so that the durability can be remarkably improved. In addition, a protruding portion 24d may be further formed on the heel of the cape 20 so that the boot 100 can be easily removed.
