Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a sole and a shoe which is easy to bend and difficult to debond. Background Art

[0002] As an indispensable object in people's daily life, shoes play an important role in people's lives. Vulcanized shoes: with rubber, fabric or leather as the upper, rubber as the base material, processed by pasting, molding or injection, and then vulcanized at a certain temperature and pressure, giving the upper and sole high strength and high elasticity, and making the two firmly combined. The bottom wall is the side part of the connection between the sole and the upper, which plays a role in reinforcement and beauty. The edge is a long strip of material, which is not a whole with the sole. It is necessary to surround the edge by gluing and combine it to the outer surface of the bottom wall. Therefore, during the use and wearing process of customers, the edge corresponding to the bending part of the sole and the position between the finished shoe is very easy to debond, resulting in unstable product quality and complicated after-sales problems, which seriously shortens the service life of the shoes. In addition, the sole of this vulcanized shoe with a bottom wall edge is usually very hard, not easy to bend and easy to crack at the bending part of the sole, affecting the wearing comfort and placing a relatively large burden on the bending of the sole. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a sole and a shoe which are easy to bend and not easy to debond. A new structural design is made at the bending part of the sole. Compared with traditional vulcanized shoes, the edge of the shoe at the bending part of the sole is not easy to debond, and the sole is easy to bend at the bending part of the sole. The utility model has the advantages of long service life and comfortable wearing of the shoes.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a shoe sole which is easy to bend and not easy to debond, comprising a base, a bottom wall and an edge;

[0006] The bottom of the base is formed with a bending groove along the bending part of the sole,

[0007] The outer side of the base is surrounded by a bottom wall, and an assembly space for assembling the upper is formed between the top of the base and the inner side of the bottom wall.

[0008] The outer surface of the bottom wall is formed with an installation groove adapted to be installed along the edge.

[0009] An upward convex structure is formed in the installation groove of the bottom wall at a position directly opposite to the bend of the sole of the base, and an upward deep groove is formed on the side of the convex structure facing the base.

[0010] A groove structure is formed on the edge and matches the protrusion structure on the bottom wall.

[0011] Furthermore, the depth of the groove structure along the edge is less than or equal to 1 / 4 of the width of the edge at that location.

[0012] The edge is grooved at the bend of the sole, and the cross-sectional area of ​​the edge in this area is greatly reduced, thereby forming an area narrower than the width of the entire edge, reducing the cross-sectional area of ​​the bending width of the edge, reducing the stress of the edge at the bend, facilitating the bending of the shoe, and reducing the probability of edge debonding, which is particularly suitable for high-walled soles and thick-soled shoe styles, greatly reducing the edge debonding rate. In some specific embodiments, the groove structure of the edge can be a truncated structure that runs through the top and bottom, that is, the edge is truncated.

[0013] Furthermore, the top of the protruding structure and both sides of the bottom of the protruding structure are arc-shaped transition structures.

[0014] Through the above arrangement, after the edge is bonded to the bottom wall, when the shoe is bent, the bending stress on the edge at the bending part of the sole can be well dispersed.

[0015] Furthermore, the bending groove extends along the width direction of the base, and both ends thereof extend to the bottom wall respectively.

[0016] By digging grooves on the base, it can be an integrally formed base, forming a deep bending groove at the bend of the sole, or a combined bottom segmented base, the base is truncated or thinned at the bend, which can reduce the obstruction stress at the bend and make the bend easier to bend. Preferably, the bending groove extends along the width direction of the base, and its two ends extend to the bottom wall respectively, which is convenient for processing and forming the bending groove on the base, and on the other hand, further reduces the obstruction stress at the bend, ensuring that the sole has a better bending effect.

[0017] Furthermore, a positioning line is provided on the edge, and an alignment line is provided on the outer side of the base, and the alignment line cooperates with the positioning line for positioning, so that the edge is fixed on the base according to a predetermined position.

[0018] Preferably, the alignment line is located at the toe position on the base. Since the length of the edge is long and the width of the edge at the toe position is usually small and the bending arc is large, the installation position of the edge at the toe position is difficult to locate. Therefore, a positioning line is set at the toe position of the edge, and an alignment line is correspondingly set at the toe position on the base. Through the coordination of the positioning line on the edge and the alignment line on the base, the edge can be accurately fixed on the base according to the predetermined position.

[0019] Furthermore, the positioning line is a linear groove, and the alignment line is a linear protrusion.

[0020] Furthermore, the softness of the edge is greater than the softness of the base, and the material of the edge and the base is silicone, polyvinyl chloride, polyurethane, ethylene-vinyl acetate, rubber, thermoplastic rubber, artificial leather, genuine leather, woven cloth or microfiber synthetic leather.

[0021] In specific applications, the softness along the edge is softer than that of the base, and it is not easy to generate longitudinal shear force, thereby preventing the debonding of the edge and the base due to the base being too soft.

[0022] The utility model also provides a pair of shoes, the sole of the shoe is the above-mentioned sole which is easy to bend and not easy to debond.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] The base is made of hard materials with wear-resistant properties such as rubber. At the bend of the sole, the shoe will form stress in the opposite direction to prevent the foot from bending. This feature is particularly serious for vulcanized shoes with high edges and thick soles, which seriously affects people's wearing comfort. In the utility model, a groove is dug on the base to form an area that is thinner than the thickness of the entire shoe base. It can be an integral molded base with a deep bending groove formed at the bend of the sole, or it can be a combined bottom segmented base. The base is cut or thinned at the bend, which can reduce the obstructive stress at the bend, make the bend easier to bend, and improve the comfort of wearing. The shoes are more comfortable to wear. In addition, a groove is dug along the edge at the bend of the sole to form a groove structure, and an upward convex structure is formed in the installation groove of the bottom wall. The groove structure along the edge is adapted to be installed with the convex structure on the bottom wall, and the cross-sectional area of ​​the edge at the bend of the sole is greatly reduced, thereby forming an area that is narrower than the width of the entire edge, reducing the cross-sectional area of ​​the bending width of the edge, reducing the stress on the edge at the bend, facilitating the bending of the shoes, and reducing the probability of degumming along the edge. It is especially suitable for soles with high bottom walls and thick soles, and the degumming rate along the edge is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] This embodiment provides a shoe sole that is easy to bend and not easy to debond. Figures 1 to 4 As shown, it includes a base 2, a bottom wall 4 and an edge 8;

[0036] The base 2 is made of a hard material with wear-resistant properties such as rubber. At the bend of the sole, the shoe will form stress in the opposite direction to prevent the foot from bending. This feature is particularly serious for vulcanized shoes with high edges and thick soles, which seriously affects the wearing comfort of people. Therefore, a bending groove 3 is formed at the bottom of the base 2 along the bend of the sole to form an area that is thinner than the entire shoe base 2. It can be an integral molded base 2 with a deep bending groove 3 formed at the bend of the sole, or it can be a combined bottom segmented base 2 (the bottom film is rubber or other hard materials, and the midsole is ethylene-vinyl acetate copolymer foam or other light and soft materials). The base 2 is cut off or thinned at the bend to reduce the obstructive stress at the bend, making the bend easier to bend and improving the wearing comfort of the shoe.

[0037] A bottom wall 4 is provided around the outer side surface of the base 2, and an assembly space for the assembled upper 11 is formed between the top of the base 2 and the inner side surface of the bottom wall 4. A mounting groove 5 adapted to be installed along the edge 8 is formed on the outer side surface of the bottom wall 4. The shape and size of the mounting groove 5 are adapted to the shape and size of the edge 8, and can be adjusted according to the shape of the edge 8 during processing. An upward protruding structure 6 is formed in the mounting groove 5 of the bottom wall 4 at a position opposite to the bend of the sole of the base 2, and an upward deep groove 7 is formed on the side of the protruding structure 6 facing the base 2, and a groove structure 9 adapted to the protruding structure 6 on the bottom wall 4 is formed on the edge 8. The edge 8 is grooved at the bend of the sole to form a groove structure 9, which greatly reduces the cross-sectional area of ​​the edge 8 at the bend of the sole, thereby forming an area narrower than the width of the entire edge 8, reducing the bending width cross-sectional area of ​​the edge 8, reducing the stress of the edge 8 at the bend, facilitating the bending of the shoe, and reducing the probability of debonding of the edge 8, which is particularly suitable for the sole 1 of the high bottom wall 4 and the shoe style with a thick bottom, greatly reducing the debonding rate of the edge 8. The bottom of the raised structure 6 of the bottom wall 4 is formed with a deep groove 7, which further facilitates the bending of the shoe and reduces the stress of the edge 8 at the bend.

[0038] Among them, the depth of the groove structure 9 along the edge 8 is less than or equal to 1 / 4 of the width of the edge 8 at that location. Through simulation experiments, the cross-sectional area of ​​the edge 8 at the bend of the sole is greatly reduced, thereby forming an area with a narrower width than the entire edge 8, greatly reducing the cross-sectional area of ​​the bending width of the edge 8, reducing the stress of the edge 8 at the bend, facilitating the bending of the shoe, and significantly reducing the probability of degumming along the edge 8, which is especially suitable for the sole 1 with a high bottom wall 4 and the shoe style with a thick bottom, so that the degumming rate of the edge 8 is greatly reduced. In some specific embodiments, the groove structure 9 along the edge 8 can be a truncated structure that runs through from top to bottom, that is, the edge 8 is truncated.

[0039] The top of the protruding structure 6 and both sides of the bottom of the protruding structure 6 are arc-shaped transition structures. Through the above arrangement, after the edge 8 is bonded to the bottom wall 4, when the shoe is bent, the bending stress on the edge 8 at the bending part of the sole can be well dispersed.

[0040] Among them, the bending groove 3 extends along the width direction of the base 2, and its two ends extend to the bottom wall 4 respectively. On the one hand, it is convenient to process and form the bending groove 3 on the base 2, and on the other hand, it further reduces the hindering stress at the bending point, ensuring that the sole 1 has a better bending effect.

[0041] Among them, a positioning line 10 is provided on the edge 8, and an alignment line is provided on the outer side of the base 2. The alignment line cooperates with the positioning line 10 to position the edge 8 on the base 2 according to a predetermined position. Preferably, the alignment line is located at the toe position on the base 2. Since the edge 8 is long, and the width of the edge 8 at the toe position is usually small, and the bending arc is large, the installation position of the edge 8 at the toe position is difficult to locate. Therefore, the positioning line 10 is provided at the toe position of the edge 8, and the alignment line is correspondingly provided at the toe position on the base 2. Through the cooperation of the positioning line 10 on the edge 8 and the alignment line on the base 2, the edge 8 can be accurately fixed on the base 2 according to a predetermined position.

[0042] Specifically, the positioning line 10 is a linear groove, and the alignment line is a linear protrusion.

[0043] The softness of the edge 8 is greater than that of the base 2, and the materials of the edge 8 and the base 2 are silicone, polyvinyl chloride, polyurethane, ethylene-vinyl acetate, rubber, thermoplastic rubber, artificial leather, genuine leather, woven fabric or ultra-fine fiber synthetic leather. In specific applications, the softness of the edge 8 is softer than that of the base 2 to prevent the edge 8 from being debonded prematurely due to the base 2 being too soft. The bottom wall 4 is made of the same material as the base 2.

[0044] Example 2

[0045] This embodiment provides a shoe, such as Figure 5 As shown, the sole of the shoe is the above-mentioned sole 1 which is easy to bend and not easy to debond, and also includes an upper 11.

[0046] The process of making shoes is as follows:

[0047] 1. First, select a type of last with a certain head shape, and build a base 2 on the last. A bottom wall 4 is formed around the outer side of the base 2. The bottom wall 4 and the base 2 are an integrally formed structure. A groove is dug at the bend of the sole of the foot at the bottom of the base 2 to form a bending groove 3, and the bending groove 3 extends along the width direction of the base 2, and its two ends extend to the bottom wall 4 respectively. The bottom wall 4 is designed as a half groove at the bend of the sole of the foot, and a side groove (i.e., an installation groove) is formed on the outer side of the bottom wall 4. The left and right sides of the installation groove 5 are formed with an upward convex structure 6 at the position opposite to the bend of the sole of the base 2, and an upward deep groove 7 is formed on the side of the convex structure 6 facing the base 2. A positioning line is designed at the toe position of the bottom wall 4 to produce the sole 1 of the base 2.

[0048] 2. According to the side groove design of the bottom wall 4, the style and structure of the edge 8 are designed. At the bend of the sole, the edge 8 is made thinner or cut off. The positioning line 10 on the edge 8 is consistent with the alignment line of the bottom wall 4, and the edge 8 is manufactured.

[0049] 3. Combine the prepared edge 8 and the bottom wall 4 by gluing them together.

[0050] 4. The manufactured sole 1 is attached to the upper 11 and the manufacturing is completed.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
