Description

Heel setting part for pressure distribution of insole in a shoe for women, insole having the same and shoe for women havig the insole}

The present invention relates to a shoe midsole, and more particularly, to a midsole having a structure capable of dispersing the pressure applied to the sole in a heeled women's shoes.

The foot is an elaborate and delicate organ composed of many bones, joints, ligaments and numerous muscles and tendons. These foot components form a basic fixed structure to perform the function of the foot well in the line state and the moving state, and forms a few formal shapes and structures by the combination of each other in each state.

Shoes can play a positive role in protecting these feet from damage from external heat, cold, and contact with external objects, and alleviating the impact on the feet during movement. However, shoes, on the other hand, may have a negative effect on the foot by limiting natural foot movement.

For example, women's dress shoes with high heels of 5 cm or more, that is, in the case of high heels, the first step of walking, rather than the natural four-step walking based on the shape of the walking foot. That is, when walking, the shape of the foot is fixed by the shape of the high heels itself in the form of a magpie foot similar to the type 2 plantar flexion that always holds the heel. In addition, the high heels are pushed to the forefoot in four stages while the second type plantar flexion continues without the first type plantar flexion. Therefore, when walking high heels, the elasticity of the muscles due to the deformation of the foot muscles are not fully utilized, and the plantar flexion function in the pushing motion of the toes is significantly reduced.

In addition, the high heels have a forefoot with a sole that touches the ground even when the user moves or stops, and a rear foot (heel) spaced a certain distance from the ground by a high heel, so that the inclination of the bottom of the shoe is inevitable, Due to the inclination of the portion connecting the forefoot and the forefoot, the forefoot of the foot is not stable on the shoe and is always forced to the front of the shoe along the inclination of the inner surface of the shoe. By this force, the user's weight is concentrated on the heel, and the narrow cheeks in front of the shoe are likely to cause hallux valgus.

On the other hand, ordinary shoes have a midsole on the sole, and the periphery of the upper is fitted and fixed between the sole and the midsole along the periphery. Inside the periphery where the upper is fitted, a sponge layer is installed to remove the step instead of the upper and to adhere the sole to the midsole. The midsole of the high heels is a piece of paper, leather or artificial leather tack over the sole of the sole and the bottom of the tack (from the end of the foot to the back of the heel of the foot, ie the boundary where the sole touches the ground). Compared to the thick and hard to form a certain shape of the band. The inside of the band has a metal waistband, also called shank, in the longitudinal direction, which serves as a support frame. That is, the inclined portion of the shoe window connecting the heel portion and the heel portion of the sole is prevented from collapsing or falling due to the user's weight or movement on the portion to maintain the inclined shape of the shoe sole.

However, the normal midsole simply serves to fix the upper, and to cover the upper periphery attached to the sole of the shoe when viewed from the inside of the shoe, it was difficult to make the foot particularly comfortable or to have a function that suits the characteristics of the user. . In this state, the top of the sole of the high heels is finished with a thin layer of cover called 'carre', so that the upper surface of the midsole is the same as the upper surface of the shoe that the user's sole touches. This is a structure that is not comfortable to give functionality, such as many functional sneakers developed in recent years, especially in the case of high heels has become a factor that makes it difficult to give a functional enough to cover the structure that gives a burden to the user's feet.

The present invention is to solve or alleviate the problems of the conventional high-heeled shoes described above, and more particularly, in the high-heeled shoes to ease the phenomenon of the back squeezing of the foot in front of the configuration by distributing the pressure applied to the soles to ease the foot The purpose is to provide.

An object of the present invention is to provide a shoe and parts that can provide a functional form to the midsole of the high heel shoe to distribute the pressure of the sole compared to the simple flat midsole to pursue the stability and comfort of the foot.

An object of the present invention is to provide a shoe and a part which can at the same time pursue the above object inexpensively and efficiently.

Women's shoe midsole for women of the present invention for achieving the above object is made of a hard synthetic resin material to cover the corresponding area of the second half of the foot while maintaining the shape without being easily deformed by external force, the shank portion formed thicker than the surrounding Characterized in that formed.

The band of the present invention can be formed through plastic injection molding or molding.

In the present invention, the shank portion is formed by protruding the bottom of the band, and usually forms a longitudinally extending shape for the purpose of the shank portion.

Shape line (S) for the inner upper surface of the abdomen in the present invention has a convex portion upward from the straight line when connecting both ends in a straight line, when the most spaced apart point in the straight line among the convex portion is the maximum separation point, both ends The ratio of the length of the straight line connecting and the maximum separation distance (D1) from the straight line to the contour line may be 10% or more, and the maximum separation point (X) of the contour line (S) is half of the straight line (M). ) Can be located perpendicular to the straight line (M ') in front of the (M) to meet the shape line.

When the side of the midsole is applied to the shoe when viewed from the side, the upper surface along the longitudinal direction as a whole (horizontal plane) and the heel corresponding part and the front of the heel corresponding part which forms a weak inclined state of 15 degrees or less. It may be provided with an inclined portion that is unfolded and has a difference of 30 degrees or more from the heel corresponding portion and the inclined angle and a curved portion connecting the heel corresponding portion and the inclined portion to form a steep inclination of 45 degrees or more with the ground. The heel corresponding part generally means from the rear end of the foot to just below the part called the astragalus, but here it means a part including at least 2/3 or more of the horizontal length from the rear end of the foot to the lower part of the astragalus. The connecting portion preferably has a horizontal length of 40% or less than that of the heel portion, and the front of the inclined portion usually has a convex downward portion for natural connection with the ground (horizontal surface).

The women's shoe midsole of the present invention is provided with a tack attached to at least a portion of the band of the present invention and the bottom of the band so as to cover the front of the foot in a state where the band and the tack are coupled.

In the women's shoe midsole of the present invention, the bottom of the band may be integrally provided with a shank portion protruding downward from the bottom in the longitudinal direction of the foot. In this case, the traction may have a perforated portion corresponding to the shank portion so that it does not have a step at the bottom of the midsole when it is coupled to the bottom of the abutment, or has a relaxed step compared to the height of protrusion from the bottom of the shank portion.

The women's shoe of the present invention is a women's shoe having a sole and a midsole having a heel of 5 cm or more as a flooring material, characterized in that the woman's shoe midsole of the present invention is provided.

In the women's shoe of the present invention, the upper portion and the upper portion of the tack are fixed by using a fixing member penetrating together with the upper and the tack in an area in which the midsole is formed only of the tack, and the upper portion of the lap overlaps the tack with only the adhesive to fix the upper and the midsole. Can be formed.

According to the present invention, the shoes are weighted to the heel and toe part by varying the inclination of the bottom portion of the shoe that connects the part touching the ground from the rear end spaced from the ground by a certain distance so that the heel part is horizontally placed. By dividing the pressure caused by the weight into the heel can be effectively reduced.

According to the present invention, since the band of the midsole can be easily formed integrally with synthetic resin up to the shank portion, the midsole manufacturing process cost and effort and time can be reduced, and thus, the shoe manufacturing cost can be reduced.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing a midsole according to an embodiment of the present invention, Figure 2 is a bottom view of the band according to an embodiment of the present invention, Figure 3 is a plan view of the band according to an embodiment of the present invention.

In Fig. 1, the lower layer is a tack 20 corresponding to the entire foot surface, and is generally made of paper and thinner than the band. In FIG. 1, the band 10 is provided only in an area corresponding to the latter half of the entire foot surface above the traction 20. The band 10 is formed thicker than the tack 20, and is made of a hard synthetic resin, that is, hard synthetic resin material that is not easily deformed by an external force. In the present invention, there is no shank constituting a separate member in comparison with the conventional shank of the paper material to have a separate shank (waist) of a metallic material to maintain the strength to prevent the deformation of the subband, the band 10 is It has an integral shank portion 11 protruding downward from the bottom and extending in the longitudinal direction. Since the synthetic resin material band can be formed by using a mold or by injection molding method, once the mold is formed, it does not incur the processing cost by separate manual work to form the shank portion, so that time in manufacturing shoes or midsoles, Save money and effort.

FIG. 4 is a side view viewed from the inner side (the middle point of the two feet of the shoe wearer) while the belt is applied to the midsole and mounted on the shoe according to an embodiment of the present invention, and FIG. 5 is the band 10 in FIG. The uppermost line (S: hereinafter referred to as a shape line) corresponding to the inner upper surface of is a graph showing the height change and the length change from the rear end as compared with the band of a conventionally designed women's shoe.

The sub-shape line (S) is in the longitudinal direction of the upper surface (horizontal plane) and 15 degrees or less more specifically, the tangential line at each point is inclined in the range of 10 to 15 degrees, and in general a gentle slope of about 11 degrees The corresponding heel portion (A) is made to be close to the straight line by a certain distance (half of the horizontal length of the whole band in horizontal length) from the back end of the band.

Next, the heel corresponding to the heel when the connecting portion (B) in which the tangent inclination at each point is in the range of 15 degrees to 50 degrees, and the straight line connecting both ends has an overall inclination of about 35 degrees is viewed as a horizontal length. It is 35% of the length of (A).

Following the connection part C, the inclination part B which is almost straight ahead along the longitudinal direction of a foot is located. The inclined portion B has a shape line length of inclined state of about 65% of the heel corresponding portion, and the inclined portion is 52 degrees to 53 degrees. In front of the inclination portion (B) may have a convex portion (E) convex downward for a natural connection with the ground (horizontal surface).

The shape line S of the inner upper surface of the abdomen has a convex portion upward and a convex portion downward from a straight line when connecting both ends in a straight line, and has a maximum separation point most spaced apart from the straight line among the convex portions upward. The ratio of the length of the straight line connecting both ends and the maximum separation distance (D ₁ ) from the straight line to the shape line is 10% or more, preferably 12% or more, and in a wearable structure, a certain value, for example, 20% or more Difficult, about 15% here. Further, when the straight line is referred to, the maximum separation point X of the shape line S is perpendicular to the straight line at the half point M of this straight line and meets the shape line S (on the heel side). Present in)

The shape line S 'which is drawn by the medial inner top surface of the conventional high heels with respect to such a medial top surface shape line is a form in which the heel portion and the inclined portion of the present invention are close to straight lines. Overall, it is close to a smooth curve, and above all, when connecting both ends in a straight line, the ratio of the length of the straight line connecting both ends and the maximum separation distance D ₂ of the shape line S 'from the straight line is less than 10%. . In addition, the maximum separation point X 'based on this straight line is located at or substantially behind the point that is drawn vertically at the half point of the straight line.

When comparing the embodiment of the present invention with the band of a conventional high heel midsole, the base of the midline medial top surface of the midsole is more clear than the outside of the foot with the calf and the weight is applied according to the slope of the curve. This is because the distribution becomes more distinct than the outside.

In the present invention, the inclined state (tilt) of the inner upper surface of the band may be slightly different in stability depending on the material of the cover (carry) that is covered on the shoe midsole, but in any case the calculation of the component force (specific direction component of the force) It can be seen that the heel is responsible for most of the weight on the heel, and the pressure on the heel is reduced compared to the prior art.

In the shape line of the present invention, the connecting portion preferably has a length of 40% or less based on the horizontal length compared to the corresponding heel portion, and when the connecting portion is long and the radius of curvature is large, the inclined portion and the corresponding heel portion are more naturally connected. Although it may have a shape, the slope of the inclined portion is larger, so that the foot is bent excessively at the ground portion, so it should have a length of 40% or less. On the other hand, if the length of the connecting portion is small, the radius of curvature of the connecting portion is small to match the difference in the inclination angle of the heel corresponding portion and the inclined portion. Therefore, determining the upper limit of the connection length and the lower limit of the radius of curvature may have the effect of limiting the shape and characteristics of the band, such as defining the upper limit and the lower limit of the connection length. The specific curvature of the connection may vary depending on the height of the heel and the length of the foot. However, if the curvature of the connection is too small, the object of the invention can be achieved, but since the weight of the heel is concentrated adjacent to the connection, Since the sole of the part is easily damaged by the intensive pressure of the foot, the radius of curvature is formed to 5 to 15 cm, but preferably the most urgently bent radius of curvature is 10 cm or more.

In the band of the present invention, the upper surface may be made of a smooth surface of a smooth curve such as the surface of the sole, but may be provided with a functional part that partially protrudes or is partially elastic. Therefore, the upper surface is not usually flat even in the left and right width directions. For example, the shape of the foot is concave so as to accommodate the shape of the foot in the heel. In addition, the sole of the shoe has a constant thickness, and compensates for the curved surface of the sole of the foot, which is not satisfied through the shape of the sole, for example, the inner surface of the foot, to increase the natural contact with the sole to increase the weight distribution effect. The thickness of the band may be formed slightly thicker than the outside on the inside.

In addition, the band of the present invention is difficult to give a sufficient thickness and shape change due to the limitation of the structure formed by laminating paper in the conventional paper band, but it is easy to form integrally by synthetic resin molding or injection molding. It may be easier to impart various forms depending on the purpose for correcting the pathology. For example, a slight convex portion of the inclined portion of the upper surface of the upper abdomen (12 in Fig. 3) is formed thickly so that the foot compensates for the curved surface along the side arch, or gives acupressure effect to the muscles of the foot. , Screw holes (13 in Figure 3) for coupling with the heel can be formed without additional processing.

Figure 6 is an exploded perspective view showing the form of combining the tactile and the band of the present invention to form a midsole constituting an embodiment of the present invention.

The midsole of the present invention does not have a metal shank part to prevent deformation therein, and the sub band 10 protrudes downward on the bottom and is integrally shank lengthwise extending in the longitudinal direction. ) If the sole or the tack 20 does not have a structure for accommodating the shank portion, the shoe sole is lifted in this portion, the coupling force between the components forming the shoe sole is bad, and the user's balance, stability is deteriorated. Therefore, here, the perforations 21 are formed in the region of the tack 20 corresponding to the sub-shank 11 indicated by the dotted line. Therefore, as shown in the drawing, the shank portion 11 is inserted into the fabric study 21, and when the adhesive 71 is applied to the upper and lower surfaces of the tack at other contacting portions and adheres closely, the entire midsole has no large step. It becomes a face.

Figure 7 is a partially cut perspective view showing an embodiment of a women's shoe formed by applying the midsole constituting an embodiment of the present invention, Figure 8 is a partially enlarged view showing a laminated structure of the cut portion.

The women's shoe of the present invention is mainly aimed at women's shoes having a sole 40 and a midsole, which includes a heel 50 as the flooring material, preferably 5 cm or more. In the case of an adult foot of 5 cm or more, the inclination of the sole of the shoe, the pathology of the high heels, and the feeling of use are relatively strong.

Also in this embodiment, the sole 40 and the midsole are used as the sole (bottom), the upper 30 is interposed between the sole 40 and the midsole in the periphery. Upper 30 is first coupled with the midsole, in this state is coupled with the sole 40, where the midsole is formed only of the tack 20 in the upper 30 and the portion of the tack 20 overlaps with the upper and the tack Fix using a fixing member 73 that penetrates together. Of course, the adhesive 71 may be further used in this part. In such a case, the upper portion and the midsole 10 may be formed by fixing the upper and the midsole only with the adhesive 71 at the portion where the band 10 overlaps with the traction 20. This is because it may be difficult to install the fixing member for fixing the midsole and the upper 30 to each other in the state that the hole for the fixing member 73 is not drilled in the band. Here, the fixing member may be any one of various existing fixing members such as pins, nails, bolts, stapler cores, and the like.

On the other hand, in the sandal-type shoes where the upper part is coupled to the midsole and mainly concentrated on the front part of the foot, it is not necessary to use a fixing member for coupling the upper 30 to the lower arm 10, and the lower arm 10 overlaps. When combining the midsole and upper 30 in the form of a string only in a portion of the midsole can be formed in advance in the manufacturing step, such as molding a hole for coupling the fixing member to the belt.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. .
