Description

Technical Field

[0001] The invention relates to the technical field of soles, in particular to a shoe sole with sawdust patterns. Background Art

[0002] The structure of the sole is quite complicated. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be water resistance, heat resistance, pressure resistance, good elasticity, easy to adapt to the foot shape, and heat preservation.

[0003] However, while some of the soles currently have the above properties, they cannot have the characteristics of being light and tough. At the same time, the soles generally have no patterns or simple patterns, and the aesthetics are relatively average. When combined with the uppers, the overall aesthetics cannot be improved. In addition, the existing soles cannot provide good breathability when worn because they need to be strictly waterproof. Moreover, when worn, if perspiration occurs, sweat will accumulate in the shoes, resulting in excessive moisture, discomfort and easy slipping. Summary of the invention

[0004] The object of the present invention is to provide a wood bran pattern shoe sole to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a wood bran pattern sole, comprising a polyurethane shoe shape, the bottom of the polyurethane shoe shape is provided with a wood bran pattern TPU bottom film, the top of the polyurethane shoe shape is provided with a microfiber leather layer, the top of the microfiber leather layer is provided with a wood bran pattern TPU top film, and one side of the top of the polyurethane shoe shape is fixedly embedded with a plurality of U-shaped support tubes;

[0006] An expansion strip is fixedly embedded on the other side of the top of the polyurethane shoe shape, the top of the expansion strip is covered with a water-absorbent cotton layer, the top of the water-absorbent cotton layer is covered with an isolation membrane, and a plurality of tension holes are evenly opened on the surface of the isolation membrane.

[0007] As a preferred technical solution of the present invention, the wood bran texture TPU bottom film and the wood bran texture TPU top film are integrally formed, and the wood bran texture TPU top film, the wood bran texture TPU bottom film, the microfiber leather layer and the polyurethane shoe shape are pressed together.

[0008] Through the above technical solution, the above materials are combined to make the sole tough, waterproof, and lightweight, while having novel and unique patterns, thereby improving the aesthetics of the shoes.

[0009] As a preferred technical solution of the present invention, one end of the wood bran texture TPU top film and one end of the microfiber skin layer are both provided with a plurality of air holes, and the positions of the plurality of air holes correspond to the positions of the openings of the plurality of U-shaped support tubes.

[0010] Through the above technical solution, when wearing the sole, the air in the shoe will pass through the air holes into the U-shaped support tube, flow through the U-shaped support tube and then be discharged.

[0011] As a preferred technical solution of the present invention, a plurality of anti-slip protrusions are fixedly connected to the middle part of the top end of the microfiber cortex.

[0012] The above technical solution can improve the anti-skid property of the sole.

[0013] As a preferred technical solution of the present invention, the bottom surface of the absorbent cotton layer is bonded and fixed to the top surface of the polyurethane shoe shape, and the bottom surface of the isolation membrane is bonded and fixed to the top surface of the polyurethane shoe shape.

[0014] Through the above technical solution, the water-absorbent cotton layer and the isolation membrane are both bonded to the surface of the polyurethane shoe shape, so that they can swell and expand freely under the push of the thermal expansion strip at the bottom.

[0015] As a preferred technical solution of the present invention, the other end of the wood bran-grain TPU top film and the other end of the microfiber skin layer are both provided with strip grooves, and the isolation membrane passes through the two strip grooves in sequence.

[0016] Through the above technical solution, the isolation membrane penetrates the wood bran-grain TPU top membrane and the microfiber leather layer and is connected to the inside of the shoe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides a polyurethane shoe shape and a microfiber leather layer, and cooperates with an integrally formed wood bran-grain TPU top film and a wood bran-grain TPU bottom film wrapped on the outside. The above materials are pressed together to form a tough, waterproof and lightweight sole. The wood bran-grain film provides a novel and unique pattern, which improves the overall aesthetics of the upper. The multiple U-shaped support tubes embedded in the polyurethane shoe shape will accelerate the flow of gas in the shoe during the extrusion and separation process between the foot and the sole, promote the gas exchange between the inside and outside of the shoe, and improve the air permeability of the shoe when wearing the sole. At the same time, the multiple U-shaped support tubes are equivalent to a reinforcing rib structure, which greatly improves the buffering capacity and anti-deformation ability of the heel of the polyurethane shoe shape.

[0019] 2. The present invention provides an isolation membrane placed on the forefoot, and a water-absorbent cotton layer and an expansion strip under the isolation membrane. When the temperature inside the shoe rises, the expansion strip can be expanded by means of high temperature, thereby pushing the water-absorbent cotton layer to open the isolation membrane, so that multiple tension holes on the isolation membrane are opened. At this time, the sweat in the shoe will be absorbed by the water-absorbent cotton layer along the tension holes, keeping the shoe dry. When the temperature inside the shoe rises and sweating is about to occur, sweat will be absorbed again, avoiding premature absorption of other moisture that causes the water-absorbent cotton layer to lose its adsorption effect. When sweating occurs, the shoe can be adsorbed again, so as to keep the shoe dry when worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 , the present invention provides a technical solution for a sawdust pattern sole:

[0027] Embodiment 1:

[0028] according to Figure 1 , Figure 2 and Figure 3 As shown, a wood bran pattern sole includes a polyurethane shoe shape 6. The main material of the sole is made of polyurethane, so that the sole has the characteristics of lightness, wear resistance and good elasticity. The bottom of the polyurethane shoe shape 6 is provided with a wood bran pattern TPU bottom membrane 5, and the top of the polyurethane shoe shape 6 is provided with a microfiber leather layer 8. The microfiber leather layer 8 improves the wearing comfort. The top of the microfiber leather layer 8 is provided with a wood bran pattern TPU top membrane 1. The wood bran pattern TPU top membrane 1 and the wood bran pattern TPU bottom membrane 5 have novel and beautiful patterns. A plurality of U-shaped support tubes 7 are fixedly embedded on one side of the top of the polyurethane shoe shape 6. The U-shaped support tube 7 is hollow inside to allow airflow to pass through. At the same time, the structure has great elasticity, which can be equivalent to a reinforcing rib structure embedded in the polyurethane shoe shape 6.

[0029] The wood chaff TPU bottom film 5 and the wood chaff TPU top film 1 are integrally formed, and the wood chaff TPU top film 1, the wood chaff TPU bottom film 5, the microfiber leather layer 8 and the polyurethane shoe shape 6 are pressed together, so that the sole has the advantages of being light, tough and elastic, and also has the wood chaff pattern to enhance the aesthetics.

[0030] One end of the wood bran-grain TPU top membrane 1 and one end of the microfiber leather layer 8 are both provided with a plurality of ventilation holes 4, and the positions of the plurality of ventilation holes 4 correspond to the positions of the openings of the plurality of U-shaped support tubes 7 respectively. The air in the shoe can pass through the ventilation holes 4, enter from one opening of the U-shaped support tube 7, and be discharged from the other opening. A plurality of anti-slip protrusions 3 are fixedly connected to the middle part of the top of the microfiber leather layer 8.

[0031] In specific use, the wood bran pattern sole of the present invention covers the top of the polyurethane shoe shape 6 with a microfiber leather layer 8 during production and processing, and then wraps the external integrally formed wood bran pattern TPU top film 1 and wood bran pattern TPU bottom film 5, and multiple materials are pressed together to form a wood bran pattern sole, and the isolation film 2 sequentially penetrates the strip grooves 9 of the wood bran pattern TPU top film 1 and the strip grooves 9 of the microfiber leather layer 8, and the multiple air holes 4 on the wood bran pattern TPU top film 1 correspond to the multiple air holes 4 on the microfiber leather layer 8 in a one-to-one manner, and then correspond to the openings at both ends of the multiple U-shaped support tubes 7 respectively. During the user's wearing and use, due to the continuous squeezing and separation of the foot and the sole, the squeezing process will squeeze the air in the shoe into the U-shaped support tube 7 (the airflow enters from one end opening). ), and the airflow is discharged from the other end along the U-shaped structure (this requires that the foot does not contact the opening at the other end during the extrusion process, because the openings at both ends of the U-shaped support tube 7 are large in number and occupy a large area, and the foot does not contact all the openings when stepping on and squeezing), so during the extrusion and separation process of the foot and the sole, the airflow will be driven to flow continuously through the U-shaped support tube 7, accelerating the air flow in the shoe, thereby promoting the gas exchange between the inside and outside of the shoe, and improving the air permeability of the shoe when wearing this sole. In addition, during long-term wearing, the multiple U-shaped support tubes 7 embedded in the polyurethane shoe shape 6 will provide elastic support. The multiple U-shaped support tubes 7 are equivalent to the role of reinforcing ribs, which improve the extrusion resistance of the heel part of the sole, improve cushioning and avoid the problem of easy damage to the heel part of the sole.

[0032] Embodiment 2:

[0033] On the basis of the first embodiment, Figure 1 and Figure 2 , Figure 4As shown, an expansion strip 12 is fixedly embedded on the other side of the top of the polyurethane shoe shape 6. The expansion strip 12 is made of heat-expandable rubber. When the temperature inside the shoe is high, that is, when sweating occurs, it expands and becomes larger, and the tension hole 10 is stretched open. In this way, when the temperature is low, that is, when there is no sweating, the tension hole 10 is relatively closed and does not absorb environmental moisture. The top of the expansion strip 12 is covered with an absorbent cotton layer 11, and the top of the absorbent cotton layer 11 is covered with an isolation membrane 2. A plurality of tension holes 10 are evenly provided on the surface of the isolation membrane 2. The bottom surface of the absorbent cotton layer 11 is bonded and fixed to the top surface of the polyurethane shoe shape 6, and the bottom surface of the isolation membrane 2 is bonded and fixed to the top surface of the polyurethane shoe shape 6. The other end of the wood bran texture TPU top membrane 1 and the other end of the microfiber leather layer 8 are provided with strip grooves 9, and the isolation membrane 2 passes through the two strip grooves 9 in sequence.

[0034] During specific use, the present invention provides a wood bran pattern sole. When wearing the sole, the forefoot will rest on the isolation membrane 2. As the temperature inside the shoe rises, indicating that sweating may occur subsequently, the high temperature causes the expansion strip 12 to expand thermally, and the increased volume pushes the water-absorbing cotton layer 11 to push up, causing the isolation membrane 2 to swell. In this way, the multiple tension holes 10 on the isolation membrane 2 will expand their apertures when supported by the bottom water-absorbing cotton layer 11, so that foot sweat will enter the water-absorbing cotton layer 11 from the multiple opened tension holes 10. The water-absorbing cotton layer 11 absorbs foot sweat and moisture in the shoe to keep the shoe dry and improve the wearing comfort. When the temperature inside the shoe rises and sweating may occur, the sweat will be absorbed again to avoid absorbing other moisture too early and causing the water-absorbing cotton layer 11 to lose its adsorption effect. The water-absorbing cotton layer 11 will be adsorbed again when sweating occurs to keep the shoe dry when sweating.

[0035] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one scheme", "some schemes", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the scheme or example are included in at least one scheme or example of the present invention.
