Description

Technical Field

[0001] This invention relates to the field of shoe sole technology, specifically to a composite fabric shoe sole accessory, shoe sole, and shoe. Background Technology

[0002] A shoe sole generally consists of an outsole and a midsole. The outsole, usually made of rubber, is attached to the bottom of the midsole and is relatively thin, serving functions such as slip resistance and wear resistance. The midsole, made of materials such as EVA, TPE, and ETPU, is thicker and serves functions such as shock absorption, support, and rebound. The outsole and midsole are combined to form the shoe sole, and the upper is then sewn or glued onto it to create a complete shoe. However, because the midsole is relatively thick, it accounts for a large portion of the shoe's weight. Therefore, increasing the midsole thickness increases the shoe's weight, while decreasing the midsole thickness reduces its shock absorption, support, and rebound effects. In the pursuit of extremely lightweight shoe soles, existing midsole structures are no longer sufficient. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a composite fabric sole accessory, sole, and shoe. This sole accessory can reduce the weight of the sole while ensuring that the shock absorption, support, and rebound effects of the sole meet the usage requirements.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A composite fabric shoe sole component is made of 3D woven nylon fabric. The shoe sole component includes a first wing, a second wing, a third wing, a fourth wing, and a main rib, all extending from front to back. The inner edges of the first and second wings are connected to the outer edges of the main rib, and both are spread outward from the inside of the shoe sole component. The outer edges of the third and fourth wings are connected to the inner edges of the main rib, and both are spread outward from the outside of the shoe sole component.

[0006] Furthermore, the first wing is located above the second wing, and their outer edges cooperate to form an outer opening. The outer opening includes, from front to back, a first enlarging section, a first narrowing section, a second enlarging section, and a second narrowing section that are smoothly connected in sequence. In the first and second enlarging sections, the opening degree of the outer opening gradually increases; in the first and second narrowing sections, the opening degree of the outer opening gradually decreases. The range of the first enlarging section in the retardation direction of the sole component corresponds to the forefoot and the front part of the arch of the human foot. The range of the first narrowing section in the retardation direction of the sole component corresponds to the rear part of the arch of the human foot. The range of the second enlarging section in the retardation direction of the sole component corresponds to the front part of the heel of the human foot. The range of the second narrowing section in the retardation direction of the sole component corresponds to the rear part of the heel of the human foot.

[0007] Furthermore, the third wing is located above the fourth wing, and their inner edges cooperate to form an inner opening. The inner opening includes, from front to back, a third expanding section, a parallel section, and a third narrowing section that are smoothly connected in sequence. In the third expanding section, the opening degree of the inner opening gradually increases; in the parallel section, the opening degree of the inner opening remains unchanged; and in the third narrowing section, the opening degree of the inner opening gradually decreases. The range of the third expanding section in the anteroposterior direction of the sole component corresponds to the forefoot area of ​​the human foot; the range of the parallel section in the anteroposterior direction of the sole component corresponds to the arch and the front part of the heel of the human foot; and the range of the third narrowing section in the anteroposterior direction of the sole component corresponds to the rear part of the heel of the human foot.

[0008] Furthermore, the main rib includes a first curved segment, a second curved segment, and a third curved segment that are smoothly connected in sequence from the front end to the rear end of the sole component; the first curved segment extends obliquely from the outside of the sole component towards the inside from front to back, the second curved segment extends obliquely from the inside of the sole component towards the outside from front to back, and the third curved segment extends obliquely from the outside of the sole component towards the inside from front to back.

[0009] Furthermore, the area occupied by the first curved segment in the front-back direction of the sole component corresponds to the forefoot of the human foot; the area occupied by the second curved segment in the front-back direction of the sole component corresponds to the arch of the human foot; and the area occupied by the third curved segment in the front-back direction of the sole component corresponds to the heel of the human foot.

[0010] Furthermore, the outer edge of the first winglet, from the front end to the rear end of the sole component, includes a fourth, fifth, sixth, and seventh smoothly connected curved segment; the outer edge of the second winglet, from the front end to the rear end of the sole component, includes an eighth, ninth, tenth, and eleventh smoothly connected curved segment; the inner edge of the third winglet, from the front end to the rear end of the sole component, includes a twelfth, thirteenth, fourteenth, and fifteenth smoothly connected curved segment; the inner edge of the fourth winglet... The front to rear end of the sole component includes a sixteenth, seventeenth, eighteenth, and nineteenth curved segments that are smoothly connected in sequence; the fourth, sixth, eighth, tenth, thirteenth, fifteenth, seventeenth, and nineteenth curved segments all extend obliquely from the inside to the outside of the sole component from front to back; the fifth, seventh, ninth, eleventh, twelfth, fourteenth, and eighteenth curved segments all extend obliquely from the outside to the inside of the sole component from front to back.

[0011] Furthermore, the areas occupied by the fourth, eighth, twelfth, and sixteenth bending segments in the retardation direction of the sole component correspond to the forefoot portion of the human foot; the areas occupied by the fifth, ninth, thirteenth, and seventeenth bending segments in the retardation direction of the sole component correspond to the arch portion of the human foot; the areas occupied by the sixth, tenth, fourteenth, and eighteenth bending segments in the retardation direction of the sole component correspond to the anterior portion of the heel portion of the human foot; and the areas occupied by the seventh, eleventh, fifteenth, and nineteenth bending segments in the retardation direction of the sole component correspond to the posterior portion of the heel portion of the human foot.

[0012] Furthermore, on a projection plane perpendicular to the vertical direction, the outer edge of the first wing is located within the outer edge of the corresponding portion of the second wing at the forefoot of the human foot, and the inner edge of the third wing is located within the inner edge of the fourth wing.

[0013] In addition, the present invention also provides a shoe sole comprising a composite fabric shoe sole component as described in any of the preceding claims, as well as a midsole and an outsole; the midsole is attached to the upper surface of the shoe sole component, and the outsole is attached to the lower surface of the shoe sole component.

[0014] In addition, the present invention also provides a shoe made of a sole as described above.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] The composite fabric shoe sole accessory provided by this invention is made of 3D woven nylon fabric. This composite fabric provides better support while having a lower density. However, the rebound performance and shock absorption performance of this composite fabric are poor. When it is applied to the shoe sole, its shape and structure need to be further improved. The composite fabric shoe sole accessory provided by this invention is equipped with a main rib and four wings, which cooperate to form a shape with an "X"-shaped cross section. The second and fourth wings located at the bottom provide support for the ground, while the first and third wings located at the top receive the force applied by the human foot. The main rib connects the four wings, and an opening is formed between the first and second wings, and also between the third and fourth wings. These two openings allow the position of the wings to move up and down relative to the main rib when the shoe sole accessory is subjected to a force perpendicular to the upper and lower surfaces. Therefore, when subjected to force, the shoe sole accessory will deform downward to provide a shock absorption effect, and when the force decreases, the shoe sole accessory will rebound to provide a rebound effect. At the same time, based on the characteristics of 3D woven nylon fabric, it can also provide better support during this process.

[0017] Therefore, the sole made based on this sole component can achieve a good balance between weight and performance. At the same time, in the sole provided by the present invention, a midsole is attached to the upper surface of the sole component and an outsole is attached to the lower surface. The midsole can ensure that the foot does not come into direct contact with the sole component, which can improve comfort, and the outsole can provide good wear resistance and anti-slip performance.

[0033] Example 1

[0034] Embodiment 1 of this invention provides a composite fabric shoe sole accessory, which is made of 3D woven nylon fabric. This 3D woven nylon fabric is a conventional nylon woven product, made by weaving nylon yarn using a 3D weaving process. Based on different 3D weaving methods, the 3D woven nylon fabric may have different structural characteristics. In this embodiment, the 3D woven nylon fabric uses a three-dimensional, five-directional weaving process, and the nylon used is nylon 66. Other parameters can be adjusted by those skilled in the art according to actual needs.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The sole components include a first wing piece 1, a second wing piece 2, a third wing piece 3, a fourth wing piece 4, and a main rib. The main rib, the first wing piece 1, the second wing piece 2, the third wing piece 3, and the fourth wing piece 4 all extend from front to back, and their shapes are roughly consistent with the shape of the sole of the foot.

[0036] Among them, reference Figure 1 The shoe sole component can be defined in directions such as front, back, top, bottom, outside, and inside. The outside and inside refer to the outer and inner sides of the human foot corresponding to the shoe sole when the shoe sole component is applied to the shoe sole.

[0037] Reference Figure 1 The inner edges of the first wing piece 1 and the second wing piece 2 are connected to the outer edge of the main rib 5, and the two are spread outward from the inner side of the sole component; the outer edges of the third wing piece 3 and the fourth wing piece 4 are connected to the inner edge of the main rib 5, and the two are spread outward from the outer side of the sole component.

[0038] Therefore, the sole component forms an "X" shape in cross-section. The second and fourth wings 4, located at the bottom, provide support for the ground, while the first and third wings 3, located at the top, receive the force applied by the foot. The main rib 5 connects the four wings. An opening is formed between the first wing 1 and the second wing 2, and another opening is formed between the third wing 3 and the fourth wing 4. These two openings allow the wings to move up and down relative to the main rib 5 when the sole component is subjected to a force perpendicular to the upper and lower surfaces. Therefore, when subjected to force, the sole component will deform downwards, thus providing a shock absorption effect. When the force decreases, the sole component will rebound, thus providing a rebound effect. At the same time, based on the characteristics of 3D woven nylon fabric, it also provides better support during this process.

[0039] Reference Figure 4 The first wing 1 is located above the second wing 2, and their outer edges cooperate to form an outer opening. The outer opening includes, from front to back, a first enlarging section 71, a first narrowing section 81, a second enlarging section 72, and a second narrowing section 82 that are smoothly connected in sequence. In the first enlarging section 71 and the second enlarging section 72, the opening degree of the outer opening gradually increases; in the first narrowing section 81 and the second narrowing section 82, the opening degree of the outer opening gradually decreases. The range corresponding to the first enlarging section 71 in the front-back direction of the sole component corresponds to the forefoot and the front part of the arch of the human foot. The range corresponding to the first narrowing section 81 in the front-back direction of the sole component corresponds to the back part of the arch of the human foot. The range corresponding to the second enlarging section 72 in the front-back direction of the sole component corresponds to the front part of the heel of the human foot. The range corresponding to the second narrowing section 82 in the front-back direction of the sole component corresponds to the back part of the heel of the human foot.

[0040] Reference Figure 5 The third wing 3 is located above the fourth wing 4, and their inner edges cooperate to form an inner opening. The inner opening includes, from front to back, a third enlarging section 73, a parallel section 90, and a third narrowing section 83 that are smoothly connected in sequence. In the third enlarging section 73, the opening degree of the inner opening gradually increases; in the parallel section 90, the opening degree of the inner opening remains unchanged; in the third narrowing section 83, the opening degree of the inner opening gradually decreases. The area corresponding to the third enlarging section 73 in the front-back direction of the sole component corresponds to the forefoot of the human foot; the area corresponding to the parallel section 90 in the front-back direction of the sole component corresponds to the arch and the front part of the heel of the human foot; the area corresponding to the third narrowing section 83 in the front-back direction of the sole component corresponds to the rear part of the heel of the human foot.

[0041] It should be understood that a larger opening provides better shock absorption and rebound, while a smaller opening provides better support. Based on this principle, when the human foot steps on this sole component, the openings of the first enlarged section 71 and the third enlarged section 73 gradually increase, providing a certain level of support while ensuring shock absorption and rebound in the forefoot area. The first enlarged section 71 and the first reduced section 81 work together to form an upward bulge at the corresponding position of the first wing piece 1, which can be adapted to the outer side of the arch of the human foot, allowing the force exerted on the first wing piece 1 by this part to be better distributed throughout the sole component. At the same time, the parallel section 90 corresponds to the inner side of the arch of the human foot. This part experiences less force when the human foot steps on it, and the opening opening remains basically unchanged, providing better shock absorption and rebound for the human foot. The second enlarged section 72, the second reduced section 82, and the third reduced section 83 work together to provide better support for the heel area of ​​the human foot.

[0042] Reference Figure 6 and Figure 7 The main rib 5, extending from the front to the rear of the sole component, comprises a first curved segment 61, a second curved segment 62, and a third curved segment 63 that are smoothly connected sequentially. The first curved segment 61 extends obliquely from the outside to the inside of the sole component from front to back; the second curved segment 62 extends obliquely from the inside to the outside of the sole component from front to back; and the third curved segment 63 extends obliquely from the outside to the inside of the sole component from front to back. The area occupied by the first curved segment 61 in the anteroposterior direction of the sole component corresponds to the forefoot of the human foot; the area occupied by the second curved segment 62 in the anteroposterior direction of the sole component corresponds to the arch of the human foot; and the area occupied by the third curved segment 63 in the anteroposterior direction of the sole component corresponds to the heel of the human foot.

[0043] Reference Figure 6 and Figure 7The outer edge of the first wing piece 1, from the front end to the rear end of the sole component, includes a fourth curved segment 64, a fifth curved segment 65, a sixth curved segment 66, and a seventh curved segment 67 that are smoothly connected in sequence; the outer edge of the second wing piece 2, from the front end to the rear end of the sole component, includes an eighth curved segment 68, a ninth curved segment 69, a tenth curved segment 610, and an eleventh curved segment 611 that are smoothly connected in sequence; the inner edge of the third wing piece 3, from the front end to the rear end of the sole component, includes a twelfth curved segment 612, a thirteenth curved segment 613, a fourteenth curved segment 614, and a fifteenth curved segment 615 that are smoothly connected in sequence; the inner edge of the fourth wing piece 4, from the front end to the rear end of the sole component, includes... The sixteenth, seventeenth, eighteenth, and nineteenth curved segments 616, 617, 618, and 619, which are smoothly connected, and the fourth, sixth, eighth, tenth, thirteenth, thirteenth, 615, seventeenth, and nineteenth curved segments 619, all extend from the inside to the outside of the sole component from front to back. The fifth, seventh, ninth, eleventh, eleventh, twelfth, fourteenth, and eighteenth curved segments 618 all extend from the outside to the inside of the sole component from front to back.

[0044] The areas occupied by the fourth, eighth, twelfth, and sixteenth bend segments 64, 68, 612, and 616 in the fore-and-aft direction of the sole component correspond to the forefoot of the human foot; the areas occupied by the fifth, ninth, thirteenth, and seventeenth bend segments 617 in the fore-and-aft direction of the sole component correspond to the arch of the human foot; the areas occupied by the sixth, tenth, fourteenth, and eighteenth bend segments 618 in the fore-and-aft direction of the sole component correspond to the front of the heel of the human foot; and the areas occupied by the seventh, eleventh, fifteenth, and nineteenth bend segments 619 in the fore-and-aft direction of the sole component correspond to the rear of the heel of the human foot.

[0045] It should be understood that the curvature of the main rib 5 indicates the difference in support, shock absorption, and rebound performance of the sole component on the inner and outer sides. A wider wing width can provide better shock absorption and rebound, while a narrower wing width can provide better support.

[0046] Reference Figure 6On a projection plane perpendicular to the vertical direction, the outer edge of the first wing 1, corresponding to the forefoot portion of the human foot, lies within the outer edge of the corresponding portion of the second wing 2, and the inner edge of the third wing 3 lies within the inner edge of the fourth wing 4. Since the second wing 2 and the fourth wing 4 are located below the first wing 1 and the third wing 3, their larger area provides better stability.

[0047] To further illustrate the rebound and shock absorption performance of the sole component provided in this embodiment, an impact simulation experiment was conducted on the sole component. Nylon 66 was used as the weaving material. A lightweight plate was fixed on the top of the sole component by adhesive or other means, ensuring that the plate did not detach from the sole component. A steel ball of constant mass was then impacted at the middle position of the plate. The initial velocity of the steel ball was 2.3 m / s, the rebound velocity after impact was 2.23 m / s, the peak impact force was approximately 1132.4 N, the displacement of the steel ball was 11 mm, and the contact time was approximately 0.015 s. Simultaneously, comparative verification was conducted using a conventional EVA midsole as the verification object. Its mass is 2.8 times that of the sole component in this embodiment. A lightweight plate was fixed to the top of the EVA midsole by adhesive or other means, ensuring the plate did not detach from the EVA midsole. A steel ball of constant mass impacted the center of the plate. The initial velocity of the steel ball was 2.3 m / s, the rebound velocity after impact was 2.13 m / s, the peak impact force was approximately 1132.4 N, the displacement of the steel ball was 10 mm, and the contact time was approximately 0.020 s. The experimental results show that the sole component provided in this embodiment, while significantly reducing weight, provides rebound performance and shock absorption performance that are essentially the same as or even better than those of conventional EVA midsole materials.

[0048] Furthermore, to further illustrate the support performance of the sole component provided in this embodiment, a support simulation experiment was conducted. A lightweight plate was fixed to the top of the sole component by adhesive or other means, ensuring that the plate did not detach from the sole component. The sole component was then placed on a horizontal base, and pressures of 335N, 565N, and 880N were applied sequentially to the middle of the plate. The changes in distance between the lower surface of the plate and the horizontal base were measured to be 3.2mm, 5.4mm, and 7.6mm, respectively. Simultaneously, a comparative verification was performed using a conventional EVA material midsole, which has a mass 2.8 times that of the sole component in this embodiment. A lightweight plate was fixed to the top of the EVA material midsole by adhesive or other means, ensuring that the plate did not detach from the EVA material midsole. The EVA material midsole was then placed on a horizontal base, and pressures of 335N, 565N, and 880N were applied sequentially to the middle of the plate. The changes in distance between the lower surface of the plate and the horizontal base were measured to be 3.4mm, 6.1mm, and 8.2mm, respectively. The above experimental results show that the shoe sole accessories provided in this embodiment not only greatly reduce weight, but also have better support performance.

[0050] Embodiment 2 of the present invention provides a shoe sole, which includes a composite fabric shoe sole accessory as provided in Embodiment 1, as well as a midsole and an outsole, wherein the midsole is attached to the upper surface of the shoe sole accessory and the outsole is attached to the lower surface of the shoe sole accessory.

[0051] The midsole and outsole can be bonded to the shoe sole components. Since the midsole, outsole, and shoe sole components are all made of polymer resin materials, they can be bonded and fixed by melting and heating.

[0052] In this embodiment, the midsole is made of EVA material, and its lower surface shape is adapted to the upper surface shape of the sole component. Because EVA material is relatively soft, it can provide good wearing comfort. The outsole is made of nylon material, which can provide good anti-slip and wear-resistant properties.
