Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoes, in particular to a durable and breathable shoe without foot clamping. BACKGROUND

[0002] With the improvement of people's living standards, the comfort and functionality requirements of daily wear are also increasingly high. As one of the indispensable supplies in daily life, the design and manufacturing technology of shoes are constantly improving to meet the needs of consumers for beauty, comfort, durability and other aspects.

[0003] Many shoes on the market have taken into account the problem of breathability in design. Generally speaking, the vamp adopts various breathable materials such as mesh, breathable leather or 3D printed breathable structure to improve the air circulation inside the shoe and reduce the moisture feeling of the foot and improve the comfort of wearing. However, although the vamp breathability has been improved, the soles of most shoes still use relatively closed materials such as rubber, plastic, etc., which perform well in waterproofness and wear resistance, but perform poorly in breathability.

[0004] The breathability of the sole is particularly important for people who wear shoes for a long time. Due to sweating of the feet and influence of external temperature, if the sole lacks effective ventilation structure, it is easy to cause moisture accumulation in the shoe, resulting in hot and humid feet, which may cause foot odor, athlete's foot and other health problems in the long run. In addition, if the sole does not have good drainage and ventilation function, once the shoe is wet, the water is difficult to drain and evaporate through the sole, which not only increases the weight of the shoe, but also prolongs the drying time of the shoe, affecting the comfort and hygiene of wearing.

[0005] Chinese utility model patent CN201220561351.6 discloses a shoe sole with a breathable and odor-resistant structure. The shoe sole directly and smoothly communicates the gas diffusion and exchange environment inside and outside the shoe through small holes uniformly distributed on the plastic or rubber sole, substantially significantly improving its breathability. In order to make the shoe both breathable and waterproof, a layer of breathable and waterproof high-molecular functional film PTFE is coated on the inner surface of the sole to provide better wearing convenience. In addition, the small ventilation holes in the sole are filled with soft and breathable activated carbon fiber material to reduce the odor inside the shoe by using the adsorption function of the material.

[0006] Although the shoe sole disclosed in the above patent document is provided with ventilation holes, which can play a role in ventilation and prevent foot clamping, the material of the shoe sole is plastic or rubber, and the existence of the ventilation holes reduces the strength and durability of the sole.

The expressions "include", "contain", "have" and the like also mean "not limited to" (certain units, components, materials, steps, etc.).

[0035] The terms such as "upper", "lower", "left", "right", "front", "back" and the like in the present application are generally used for the purpose of intuitive understanding with reference to the drawings, and are not an absolute limitation on the positional relationship in the actual product. Changes in these relative positional relationships are also considered within the scope of the present application when the technical concept disclosed in the present application is not departed from.

[0036] The present embodiment provides a ventilated shoe, which comprises a left shoe and a right shoe, and the structures of the left shoe and the right shoe are symmetrical.

[0037] Referring to Figure 1The ventilated shoe provided by the embodiment comprises a shoe sole 1 and a shoe upper 2, the shoe sole 1 and the shoe upper 2 jointly form a shoe cavity, the shoe sole 1 comprises a steel plate layer and a plastic wrapping layer which is plasticized on the periphery of the steel plate layer, a plurality of ventilating holes 11 are arranged on the shoe sole 1, the ventilating holes 11 penetrate the plastic wrapping layer and the steel plate layer, and Figure 2 A rubber block 12 is arranged in the ventilating hole 11, and a gap allowing gas to flow is formed between the inner wall of the ventilating hole 11 and the side wall of the rubber block 12. Figure 4 The upper surface of the shoe sole 1 is provided with a partition layer, a through hole corresponding to the ventilating hole 11 is formed in the partition layer, and the partition layer is tightly connected with the shoe sole 1.

[0038] The shoe sole 1 of the ventilated shoe provided by the above embodiment provides the strength and rigidity of the shoe sole 1 through the steel plate layer, and the plastic wrapping layer increases the wear resistance and flexibility of the shoe sole 1, so that the shoe sole 1 is both solid and has a certain elasticity, and the wearing comfort is improved; at the same time, the ventilating holes 11 which directly communicate the inside of the shoe cavity with the external environment are arranged on the shoe sole 1, which is beneficial to the discharge of moisture and heat, ventilates, prevents odor and does not cover the feet; in addition, the wearing comfort and the adjustment flexibility of the tightness of the shoe opening 3 are improved through the design of the two slide ways on the shoe upper and the shoe rope 4, and people with different thicknesses of instep can be adapted.

[0039] The structure of the rubber block 12 can also be optimized on the basis of the ventilated shoe provided above. Specifically, in the embodiment, the side wall of the rubber block 12 is adaptively connected with the hole wall of the ventilating hole 11 on the steel plate layer, a plurality of connecting protrusions are arranged on the side wall of the rubber block 12, a plurality of connecting grooves for mounting the connecting protrusions are arranged in the hole wall of the ventilating hole 11 on the steel plate layer, the connecting protrusions and the connecting grooves are one-to-one corresponding, and the connecting protrusions and the connecting grooves are connected in an interference fit.

[0040] In this embodiment, the interference fit connection between the connecting protrusions and the connecting grooves can significantly improve the connection stability between the rubber blocks 12 and the steel plate layer, preventing displacement or falling of the rubber blocks 12 due to long-term wearing or intense exercise; the one-to-one correspondence between the connecting protrusions and the connecting grooves allows the rubber blocks 12 to be embedded in the steel plate layer, enhancing the overall structure of the shoe sole 1 and helping to improve the durability and service life of the shoe sole 1.

[0041] In the specific production process, the structure design of the connecting protrusions and the connecting grooves facilitates standardized production, allowing large-scale production using molds to improve production efficiency and reduce costs.

[0042] In other embodiments, an elastic block made of a thermoplastic elastomer material can also be used to replace the above-mentioned rubber blocks 12, so that the elastic block can be connected with the steel plate layer by hot plastic forming, making the connection very reliable and firm.

[0043] The structure of the steel plate layer can also be optimized based on the above-mentioned breathable shoes. Specifically, in this embodiment, the steel plate layer in the shoe sole 1 is composed of one steel plate or multiple steel plates, and the multiple steel plates are arranged in a horizontal direction along the toe to the heel direction.

[0044] The steel plate layer in the shoe sole 1 is arranged as multiple spaced steel plates, which reduces the amount of steel plate compared to a whole steel plate, and can relatively reduce the overall weight of the shoe sole 1 while maintaining the required strength and rigidity; at the same time, the spaced steel plates can provide more flexibility, as there can be a certain space between each steel plate, which better fits the natural shape of the foot, making the shoe sole 1 more natural and comfortable when bending; during production, each steel plate can be designed to correspond to the key support areas of the foot, such as the arch and the heel, to provide better local support and stability.

[0045] In other embodiments, carbon fiber plates can also be considered as a replacement for steel plates. Carbon fiber has a higher strength-to-weight ratio, which can provide the same strength and rigidity while being lighter in weight, but the cost of making breathable shoes will be higher.

[0046] Of course, using steel plates can increase the weight of the shoes, which can be used as weight-bearing shoes, and is more suitable for people who usually exercise. Preferably, the thickness of the steel plate is 1-2 mm. In actual production, the thickness of the steel plate can also be customized according to user needs.

[0047] The connection structure of the shoe sole 1 and the spacer layer will be described below. The upper surface of the shoe sole 1 is provided with a spacer layer, and a through hole corresponding to the air hole 11 is formed in the spacer layer. The size and shape of the spacer layer are basically consistent with those of the shoe sole 1. The edge of the spacer layer is fastened and connected to the steel plate layer in the shoe sole 1 through fastening screws, which are screwed into the threaded holes in the steel plate layer after penetrating the mounting holes in the plastic wrapping layer.

[0048] The use of fastening screws to fix the spacer layer and the steel plate layer can provide a very stable connection and ensure that the spacer layer will not loosen or shift during long-term use. In addition, the through hole formed in the spacer layer corresponds to the air hole 11, ensuring the air permeability of the shoe sole 1 and helping to expel moisture, thereby improving the comfort of wearing. If the spacer layer is damaged or needs to be replaced, the design of the fastening screws makes it relatively simple to disassemble and reassemble the spacer layer, thereby prolonging the service life of the air-permeable shoes. Furthermore, the use of fastening screws can reduce the use of materials during manufacturing, as there is no need to completely fuse the materials of the spacer layer and the shoe sole 1 or use a large amount of adhesive.

[0049] In other embodiments, the connection between the shoe sole and the spacer layer can also be achieved in the following ways:

[0050] 1. Adhesive connection: using structural glue or other types of adhesives to bond the spacer layer to the shoe sole. This method can achieve a very smooth and seamless connection, but it is not as easy to disassemble as screw connection.

[0051] 2. Buckle connection: designing a buckle structure on the edge of the spacer layer, which can be directly inserted into the corresponding groove on the edge of the shoe sole, achieving quick disassembly and installation.

[0052] 3. Heat fusion: using heat fusion technology to fuse the spacer layer with the materials of the shoe sole, which is suitable for thermoplastic materials and can form a monolithic shoe sole structure.

[0053] 4. Elastic frame: designing an elastic frame on the edge of the spacer layer, which can be elastically inserted into the corresponding groove on the edge of the shoe sole, achieving flexible and stable connection.

[0054] In this application, the shape of the plurality of air holes 11 provided on the shoe sole 1 can be any one or a combination of circular, elliptical, triangular, square, pentagonal, or hexagonal shapes. Of course, it can also be other shapes that are easy to process. If the air hole 11 is a circular hole, the hole diameter can be set to 1-3 cm. The shape of the rubber block 12 provided in the air hole 11 can be the same as that of the air hole 11, or it can be different from that of the air hole 11, such as a square rubber block 12 provided in a circular air hole 11.

[0055] In this embodiment, the top of the rubber block 12 is flush with the upper surface of the partition layer, making the contact surface of the shoe sole 1 smoother, helping to disperse the pressure exerted by the foot, providing more uniform support, and enhancing the overall stability of the shoe sole 1.

[0056] In other embodiments, the top of the rubber block 12 is higher than the upper surface of the partition layer, which can serve as a foot massage.

[0057] The connection structure of the shoe sole 1 and the shoe upper will be described in detail below. The shoe sole 1 has a circle of first connection holes evenly arranged near its outer edge, and the shoe upper 2 has a circle of second connection holes evenly arranged near the shoe sole 1. The first connection holes correspond one-to-one to the second connection holes, and a first connection hole and a corresponding second connection hole are connected by a connecting rope. The shoe sole 1 is connected to the shoe upper 2 by the connecting rope.

[0058] In the above connection structure, the use of the connecting rope improves the flexibility of the connection between the shoe sole 1 and the shoe upper 2, making it easy to disassemble and replace. The connecting rope can be designed as a component that is easy to replace. If the connecting rope is worn or damaged, it can be replaced individually without the need to replace the entire shoe sole 1 or shoe upper. Users can customize the fit of the shoe by adjusting the tightness of the connecting rope according to their personal preferences or foot characteristics, thereby achieving a better wearing experience. Compared to using rigid connecting components, the connecting rope is usually lighter, which helps to reduce the overall weight of the shoe, making it more lightweight. In addition, the connecting rope can provide uniform tension between the shoe sole 1 and the shoe upper, helping to improve the structural strength and support of the shoe. In specific production, the connecting rope can be designed in various colors and styles to add design elements to the shoe and improve its appearance appeal. Compared to complex sewing or bonding processes, the use of connection holes and connecting ropes can simplify the manufacturing process and reduce production costs.

[0059] In this application, the shoe upper 2 includes a left shoe upper 21 and a right shoe upper 22. The left shoe upper 21 is closely connected to the right shoe upper 22 near the front half of the toe, and the left shoe upper 21 is oppositely spaced from the right shoe upper 22 near the back half of the shoe opening 3 to form an adjustment opening 23. The tongue can be provided at the adjustment opening 23, of course, the single shoe can also not be provided with the tongue.

[0060] In this application, the first slide 211 is provided near the position of the shoe opening 3 of the left shoe upper 21, and the second slide 221 is provided near the position of the shoe opening 3 of the right shoe upper 22. The first slide 211 and the second slide 221 are respectively arranged on both sides of the adjustment opening 23.

The first slide 211 is located in front of the shoe opening 3, as shown in Figure 5The first slide 211 includes a first track slot 2111 arranged on the vamp and a strip-shaped clamping seat 2112 arranged at the bottom of the first track slot 2111, and a plurality of mounting holes 2113 are uniformly arranged on the strip-shaped clamping seat 2112; the first buckle 212 is in sliding connection with the first track slot 2111, and a fixing hole corresponding to the mounting hole 2113 is arranged on the first buckle 212; the first locking structure includes a locking screw 213, the locking screw 213 passes through the fixing hole on the first buckle 212 and one of the mounting holes 2113 on the strip-shaped clamping seat 2112 in sequence, so that one end of the shoe cord 4 is fixedly connected with the first slide 211.

[0062] The second slide 221 extends along the length direction of the breathable shoe on the vamp, and is located on the side of the shoe opening 3. The second slide 221 has the same structure as the first slide, and includes a second track slot arranged on the vamp and a strip-shaped clamping seat arranged at the bottom of the second track slot, and a plurality of mounting holes are uniformly arranged on the strip-shaped clamping seat; the second buckle 222 is in sliding connection with the second track slot, and a fixing hole corresponding to the mounting hole is arranged on the second buckle 222; the second locking structure includes a locking screw, the locking screw passes through the fixing hole on the second buckle 222 and one of the mounting holes on the strip-shaped clamping seat in sequence, so that the other end of the shoe cord 4 is fixedly connected with the second slide 221.

[0063] The above-mentioned slide buckle type shoe cord 4 design allows the shoe cord 4 to slide along the length direction of the slide, thereby providing flexible adjustment of the tightness of the shoe opening 3, and the user can adjust the fit of the shoe according to needs; the shoe cord 4 is fixedly connected with the slide through the locking screw, so that the shoe cord 4 will not loosen after intense exercise or long-term wearing, and the stability and comfort of the shoe are maintained; the slide design on the front and side of the shoe opening 3 allows the user to easily adjust and fix the tightness of the shoe opening 3, facilitating quick putting on and taking off, and the slide buckle type shoe cord 4 design is convenient for standardized production, improves the assembly efficiency of the production line, and reduces the production cost.
