{LIGHT WEIGHT SHOES}

The present invention relates to a shoe, and more particularly, to a lightweight shoe having a structure optimized for a shape and a motion of a foot and capable of improving productivity.

Shoes are intended to mitigate the impact of walking and protect the feet of pedestrians from the outside, and most people will wear them when walking.

These shoes are generally formed by forming a midsole on the bottom portion so as to correspond to the shape of the foot, and arranging an upper portion so as to cover the foot on the upper side, and are joined with the midsole.

In recent years, as consumers have become more interested in fashion and health, shoes of various types, shapes, or materials have been proposed. As a representative material of shoes, leather, fiber and synthetic resin are utilized.

In the case of shoes made of leather material, it keeps its shape relatively well because it keeps its shape relatively well, but it keeps its shape without changing its shape, but it has difficulty in wearing, and it frequently causes damage to the heel or toe part It also has weakness in ventilation.

In the case of a shoe or a sneaker made of a fiber or a synthetic resin material made of a relatively soft material, there is a comfort at the time of wearing, but a deformation is generated over time and the durability is weak.

Although various attempts have been made to overcome the disadvantages of various shoes as described above, it is very difficult to satisfy both the convenience of wearing, the durability, and the comfort of walking on the foot.

It is an object of the present invention to provide a lightweight shoe having a structure that maximizes durability and convenience of wearing.

Another object of the present invention is to provide a lightweight shoe having a structure capable of improving efficiency in a production process.

The present invention relates to an insole comprising a cover portion disposed to cover a foot from above, an insole portion coupled in a sewing manner below the cover portion and supporting the sole, The sole comprises a front elevated portion elevated from the front side to the upper side, a posterior elevated portion elevated upward from the rear side, a first elevated portion disposed laterally of the toe bone, A first ridge formed between the first ridge portion and the second ridge portion, and a second ridge portion disposed between the first ridge portion and the second ridge portion, the second ridge portion being disposed laterally of the first ridge portion and the third ridge portion disposed adjacent to the peach bone, And a second depression formed between the second ridge portion and the third ridge portion is disposed in correspondence with a connection portion between the toe bone and the foot bone to facilitate deformation in the vertical direction, Arrangement of the hinges of rippyeo is, the light weight provides a footwear characterized in that the upper side in the third depression center it upon the support of the heel on the ground is formed between three raised bumps on a rear elevated portion and a rear base. Therefore, the production process is simplified while the structural stability is excellent.

In addition, the cover portion and the insole portion may be connected to each other by a connection portion by a bonnet sewing method in a state in which the edge portions are adjacent to each other. Therefore, the feeling of wearing improves.

Preferably, the cover portion, the insole portion, and the connection portion are coupled by the shoe portion and the joint portion. Thus, the productivity is improved.

The air conditioner may further include a front cover portion covering the front side of the cover portion and made of a material harder than the cover portion and a rear cover portion covering the rear side of the cover portion and made of a material harder than the cover portion, In the front cover part, the front cover part preferably has a curved part curved forward in the third toe bone part that receives the least amount of power when walking. Therefore, it is optimized for changes in the body and durability is improved.

The cover may further include a reinforcing portion formed on the outer surface of the cover portion to form a pattern and form a skeleton. Therefore, the activity and the durability are improved.

The reinforcing portion may be made of a foam type material.

It is preferable that the reinforcing portion is formed in such a way that when the foamed ink is coupled to the surface of the cover portion and protruded, a three-dimensional shape is formed again through the press. Thus, visual satisfaction and functionality are maximized.

The length between the second ridge portion and the highest point of the third ridge portion is preferably 8 cm to 12 cm.

The lightweight shoe according to the present invention has a structure in which the cover part, the insole part, and the sole part are made of a lightweight material and the production process can be minimized, so that productivity can be improved and shoe optimized for foot shape and motion can be provided .

Further, it has a structure optimized for deformation due to the movement of the foot through the reinforced shape of the sole, and the durability can be further improved by the front cover part and the rear cover part.

In addition, since the cover part itself has a reinforcing part that can function as a skeleton, the overall shape can be supported by each section with respect to high stretchability, so that the activity is further improved.

Figure 7 is a perspective view of a lightweight shoe according to a further embodiment of the present invention;

Hereinafter, a lightweight shoe according to the present invention will be described in detail with reference to the accompanying drawings.

The lightweight shoe according to the concept of the present invention basically comprises a sole portion contacting the ground surface of the bottom portion, a cover portion arranged to cover the upper side of the sole portion, and a cover portion which is joined to the cover portion in a sewing manner, And an insole portion joined to the upper surface in an adhered manner.

The shoe sole may be formed variously according to the type of shoe, and the concept of the present invention is not limited to the following description and drawings. In the description of the present invention, the opposite side is defined as the inside and the opposite side is defined as the outside, based on the state where both feet are facing each other. Also, the inside and the outside can be defined as the inner circumference side or the inner side, the outer circumference side, or the outer side, respectively, based on a single shoe.

1 is a perspective view illustrating a lightweight shoe according to the present invention.

As described above, the present invention comprises a cover part 100, an insole part (200 in FIG. 2) and a sole part 300 from the upper side.

The sole portion 300 may be made of natural rubber or synthetic rubber to support the bottom portion of the foot at the upper side and face the ground at the lower side of the sole portion 300. The sole portion 300 may be made of natural rubber or synthetic rubber, It is not.

In the concept of the present invention, the overall shoe material is lightweight compared to conventional shoes. Therefore, the shoe sole 300 may be formed of a synthetic resin material, TPE (Thermo plastic elastomers) material, It can be selected from synthetic rubber materials.

Since the shoe sole 300 supports the overall structure and has a higher durability than other parts, the thickness of the shoe sole 300 is thicker than that of the cover 100 and the insole 200.

The shoe sole 300 may be largely divided into a bottom portion supporting the ground and a side wall portion surrounding the lower side of the cover portion 100. In order to reinforce the lightweight shoe, It may have a recessed shape. This will be described later.

The cover part 100 may be formed to surround the foot and football as a whole, and may have an opening (not shown in the figure) in which the foot can enter and leave from the upper side. In order to satisfy the concept of the lightweight shoe of the present invention, it is preferable that the material of the cover part 100 is made of a lightweight material having excellent stretchability. In consideration of stretchability, a neoprene material or a polyspan material Can be used.

Because of the elasticity of the cover part 100, the close contact with the foot and the ball is improved, and the cover part 100 can be flexibly deformed naturally due to the deformation of the foot between the feet, thereby improving the unity of the foot I have.

The cover part 100 is first engaged with the insole part 200 without directly joining to the shoe part 300. The cover part 100 and the insole part 200 shown in FIG.

The cover part 100 and the insole part 200 are combined in a sewing manner and the bottom surface of the insole part 200 is joined to the sole part 300 in such a manner that the cover part 100 and the insole part 200 are sewn together And the lower outer surface of the cover portion 100 is bonded together from the inner surface of the side wall portion of the sole portion 300 while being adhered together.

Referring to FIG. 2, the lower end of the cover part 100 is joined along the outer circumference of the insole part 200 in a sewing manner.

Conventionally, in producing the padding, the bottom portion corresponding to the insole portion is reversed while the inner surface of the upper portion corresponding to the cover portion is turned upside down, and the outer peripheral surface of the lower end side of the upper portion and the outer peripheral side of the bottom surface of the bottom portion are interviewed After sewing, it was common to turn over the upper so that the sewing surface does not look outward.

The conventional method of joining the upper part and the bottom part does not cause a problem of the outer side finishing, but there is a problem in wearing feeling because the sewn edge part protrudes from the inner side, and there is a fear of body damage to the sole or the ball depending on the case. In addition, the production process is complicated.

In the present invention, a joining method in which the cover part 100 and the insole part 200 are sewn by a Bonnier method is proposed in consideration of this. That is, the corner of the lower end of the cover part 100 and the outer circumferential edge of the insole part 200 are arranged so as to be adjacent to each other in a state in which the cover part 100 is turned upside down or the insole part 200 is not inverted, So that the cover 100 and the insole 200 can be connected to each other by a single sewing process by connecting the upper and lower portions in a zigzag manner through a sewing thread. In this case, the manufacturing process is simplified as compared with the conventional method, and there is no step or protruding part at the connection part when worn on the foot, so that it is advantageous that the wearability is improved.

A connecting portion for sewing the cover portion 100 and the insole portion 200 may be defined as a connecting portion 210 and the connecting portion 210 may be bonded to the inner circumferential side of the sole portion 300 as described later No exposure to the outside.

Meanwhile, since the insole unit 200 is in direct contact with the sole, a material having excellent wearing comfort can be adopted. Preferably, the insole unit 200 is formed of a material having a plurality of voids or through holes formed therein in consideration of moisture absorption or drainage of sweat and moisture. For this purpose, the insole unit 200 is preferably made of a synthetic fiber material having a mesh shape. But is not limited thereto. The shape of the mesh can be varied in consideration of the feel of the sole and the performance of drainage or moisture absorption.

Since the sole 300 is combined with the cover 100 and the insole 200 in a bonding manner and is formed as a lightweight material, it is possible to improve the overall performance of the support by the sole 300 .

To this end, the shoe sole 300 includes a bottom portion and a side wall portion, and the side wall portion may have a ridge or a depression shape.

As shown in FIG. 1, the sidewall portion of the sole portion 300 may include a front elevating portion 301 protruding upward from the forefoot portion and a rear elevating portion 302 protruding upward from the heel portion. The front elevating portion 301 and the rear elevating portion 302 may be symmetrically symmetrical with respect to the center line of the shoe in the forward and backward directions. Here, the symmetry is not a complete geometric symmetry but a rough Symmetrical state.

In addition, the sole portion 300 includes a first ridge 311 that is raised at a portion adjacent to the forefoot, a second ridge 312 that rises at the lateral side of the leg bone, And a third ridge 313 protruding from the lower side of the bone.

The arrangement of the raised portions can be made in consideration of the relation with the toe joint. In this connection, the joint of the toe will be described in more detail with reference to FIG.

The structure of the human foot is different for each person, and the limitations described in the present invention can be flexibly applied to various types of foot, size, and the like.

The feet are composed of heel bones 230 forming the heel and first toe thighbone 221 through fifth thigh bone 225 which are disposed on the front side of the heel bone 230 and are connected to five common toes . Here, 'first' means the innermost direction, that is, the direction in which the big toe is arranged, and 'fifth' means the direction in which the youngest toe is disposed. Thus, it should be noted that even if the number of toes is greater than or less than five, the above expression can be understood as the innermost and outermost expressions.

The first toe-to-fifth toe bones 215 are connected to muscles and ligaments, and each of the toe bones is provided with a toe joint so as to be bendable.

In the following description, when each part of the shoe corresponds to the structure of the bones constituting each foot, it means a state in which the shoe is disposed in a substantially planar adjacency, and the corresponding meaning of the shoe corresponds to the movement of the joint or the arrangement state of the skeleton. And the like.

The first raised portion 311 is disposed on the side of the fifth toe bone 215 with respect to the outer side of the shoe to support the structure of the shoe due to the deformation of the toe.

The second ridge 312 is disposed laterally of the fifth leg bone 225, more precisely on the side of the front side of the fifth leg bone, so that the first ridge 311 and the second ridge 312, A first depression (not shown) is disposed between the first depression and the second depression, and the depression is deformed according to the movement of the toe joint.

The center of the first depressed portion on the side surface is disposed at the connecting portion between the fifth toe bone 215 and the fifth footbone 225 and the portion protruded upward is minimized so that the structure optimized for vertical deformation I have.

The third ridge 313 is arranged in an upward direction from the side wall of the portion of the heel bone 230 and the second ridge 313 is disposed between the third ridge 313 and the second ridge 312, (Reference numeral not shown) is disposed. The second depression corresponds to the depression of the connection between the heel bones 230 and the depression bones 225. Since the height of the depression on the inner side of the foot is the highest, More meaningful.

On the other hand, since the inside of the foot is symmetrical with the above-mentioned matters, the overlapping description will be omitted. In other words, a first ridge 311 on the inner side is disposed laterally on the first toe bone, and a second ridge 312 on the inner side is disposed laterally on the first lower bone 221 The first depressed portion is disposed at a connecting portion between the first toe bone and the first leg bone 221.

A third depression (not shown) is disposed between the third ridge 313 and the rear ridge 302 on both sides with the heel as a center, so that when the heel is supported on the ground, So that upward bending is facilitated.

The length up to the highest point of the second ridge 312 and the third ridge 313 is preferably about 8-12 cm. Specifically, when the size of the shoe is 260 mm, the length is preferably 9.4 cm to 10.5 cm, more preferably 10 cm. The length means the length of a straight line which is the shortest distance.

Since the protrusion and depression of the shoe sole 300 as described above can maintain the shape of the lightweight shoe while being easily deformed according to the natural change of the body, the comfort and durability are improved.

In consideration of the durability, the front cover part 110 and the rear cover part 120 may be further coupled to the cover part 100 of the present invention. The front cover part 110 and the rear cover part 120 may be made of a material having a higher durability and a higher tensile strength than the cover part 100.

The front cover part 110 and the rear cover part 120 are made of a material having a stronger elasticity than the cover part 100, The front cover 110 and the rear cover 100 are preferably made of a harder material than the cover 100. For example, when the cover part 100 is made of neoprene, the front cover part 110 and the rear cover part 120 may be made of a material such as cloth, leather, or synthetic fiber.

The rear cover part 120 functions to minimize the deformation of the rear side of the shoe when the shoe is attached and detached, and to reinforce the load when the load is applied to the heel. The front cover part 110, Thereby enhancing resistance to external impacts.

The shape of the front cover part 110 and the rear cover part 120 will be described later in more detail in the description of FIG.

The rear cover part 120 may extend from the bottom part 300 to the opening part of the cover part 100 and may protrude upward from the upper end of the rear cover part 120. [ The extended portion 130 may be disposed.

The extension 139 can be gripped by hand and can function to improve ease of shoe attachment and detachment.

The extension portion 139 is integrally formed with the rear cover portion 120 and is preferably joined to the upper surface of the cover portion 100 like a front cover portion 110 in a sewing manner. It does not exclude various combinations such as a fusion method.

Fig. 4 shows a cross section of the lightweight shoe of the present invention, specifically showing a shape cut from the side where the second raised portion is disposed on the front side to the right and left.

As described above, when the cover part 100 and the insole part 200 are connected to each other by the connecting part 210 of the sewing method such as a Bonnie process in a state where their edges are adjacent to each other, The joining part 400 is applied to the outer circumference of the lower part of the cover part 100, and the joining part 400 may be made of the same material as the adhesive. It is needless to say that the joining part 400 may be applied on the upper side of the shoe sole 300 or may be disposed on the cover part 100, the insole part 200 and the sole part 300 together.

The insoles 200 and the soles 300 and the cover 100 and the soles 300 are connected to each other through the joint 400 and the connection between the insole 200 and the cover 100 210 can be further strengthened.

Here, since the joints 400 are formed on the inner surfaces of the ridges, the ridges are coupled to the cover 100.

5 is a plan view showing a state in which the cover part and the insole part are combined in the light side shoe of the present invention from the front side.

As described above, the cover part 100 can be coupled with the front cover part 110 in a form of wrapping the foot on the front side. Preferably, the inside of the front cover part 110 covers most of the first toe bones And the third toe bones 213 are arranged in such a manner that the covering portions are minimized. In addition, the fifth toe bones 215 are arranged to extend backward in the region where the fifth toe bones 215 are disposed.

This type was made considering the situation where the force is most applied to the big toe and small toe in walking. As a result, it was found that the third toe has the least power when walking. Accordingly, the front cover part 110 has a curved curved part 112 that is bent forward at a position where the third toe bone is disposed, and the rear side line of the front cover part 110 has a shape ≪ / RTI > At this time, since the width of the big toe is substantially larger than that of the other toes in terms of the width of the foot, the curved portion 112 is disposed in an outwardly biased form.

As described above, since the front cover 110 according to the present invention has an optimized shape according to the force applied to the foot during walking, it is possible to attain both the comfort and the durability improvement at the same time. In addition, according to the above-described shape, the visual satisfaction can be maximized.

The front cover part 110 and the front cover part 110 may be joined together in a sewing manner. At this time, the front cover part 110 passes through the upper and lower sides of the front cover part 110, .

Fig. 6 is a rear view showing the state in which the cover portion and the insole portion are engaged in the light-weight shoe of the present invention from the rear side.

The rear cover part 120 supports the rear side of the cover part 100 made of a soft material as in the case of the front cover part 110. It is preferable that the width of the rear cover part 120 is widest from the lower side to the left and right side in consideration of durability Do.

As described above, the rear cover part 120 has a structure in which an extension part 139 is disposed on the upper end side and can be grasped. In order to engage with the cover part 100, a rear sewing part 121 May be formed.

The front cover part 110 and the rear cover part 120 are coupled in a sewing manner before the cover part 100 is engaged with the insole part 200 and are sewn together when connected by the connecting part 210. In particular, It is preferable that they are bonded by a Bonnice sewing method.

On the other hand, the ring portion 140 may be further disposed on the opening portion of the cover portion 100 to allow the foot portion to pass therethrough, so as to surround the upper end of the opening portion.

Figure 7 is a perspective view illustrating a lightweight shoe according to a further concept of the present invention.

The cover part 100 and the insole part 200 are coupled to each other by the connecting part 210 and the cover part 100 and the insole part 200 are joined to the sole part 300 together with the joint part 400). The overlapping description with respect to this combining process and the concrete form will be omitted.

Here, the cover part 100 may be coupled to the outer surface of the reinforcement part 500 to appropriately support the foot structure against repeated deformation.

The reinforcing part 500 may function as a predetermined skeleton so as to support a force in the front, rear, or up and down directions while forming a predetermined pattern on the outer surface. The reinforcing part 500 is made of synthetic resin material, Glued, or fused to the outer surface of the base plate (not shown).

The reinforcement portion 500 may be disposed on the cover portion 100 as a predetermined uneven surface, and it is preferable that the reinforcing portion 500 is formed of a foam type in consideration of aesthetic enhancement and reinforcement performance.

At this time, the foaming formula may be formed of a polyurethane foam material, and may be formed in advance with respect to the cover part 100 in a process before the cover part 100 is engaged with the insole part 200 .

For example, the reinforcing portion 500 forms a sputtered surface on the surface of the fibers forming the cover portion 100, and injects the spatula with the mold covered. At this time, when the foamed ink is injected, it forms a three-dimensional shape and can be formed through a process of forming a uniform thickness or a thickness of a desired shape through the press.

Accordingly, the reinforcing part 500 formed can be divided into a shape that is arranged in the vertical direction and a shape that is arranged in the front-rear direction in the state where the shoe is formed, and the section formed in the vertical direction is the vertical reinforcing section 510 And the tension in the forward and backward directions is supported by the front and rear reinforcing sections 520 having the predetermined front and rear thicknesses.

In the present invention, since the cover part 100 is made of a material having a high elasticity, it has an advantage of excellent adhesion and unity, but it has a problem that it is not suitable for a strong movement, so that the activity can be further improved through the reinforcing part 500 .

The lightweight shoe of the present invention as described above has a structure in which the cover part 100, the insole part 200 and the sole part 300 are made of a lightweight material and the production process can be minimized, It is possible to provide a shoe that is optimized for the shape and movement of the foot.

Further, the sole part 300 has an optimized structure for deformation due to the movement of the foot through the reinforced shape, and the durability can be further improved by the front cover part 110 and the rear cover part 120.

Further, since the cover part 100 itself has the reinforcement part 500 that can function as a skeleton, the overall shape can be supported for each of the high stretchability, and thus the activity is further improved.
