Description

Technical Field

[0001] The present application relates to the field of protective shoes, and in particular to a protective shoe upper and a casual shoe. Background Art

[0002] In outdoor mountaineering, construction sites, factory production lines and other scenarios, workers' insteps are at risk of being hit, so they usually need to wear shoes with protective uppers.

[0003] Existing uppers with high protective performance are usually made of soft materials with high elasticity to cushion and protect the foot when foreign objects hit the foot. However, in order to ensure the aesthetics and lightness of the upper, such uppers are usually not too thick, resulting in limited protective performance. Therefore, there is a need for a protective upper that is relatively light and thin while having good protective performance. Utility Model Content

[0004] In order to make the shoe upper relatively light and thin while having good protective performance, the present application provides a protective shoe upper and casual shoes.

[0005] On the one hand, the present application provides a protective shoe upper adopting the following technical solution:

[0006] A protective shoe upper includes a shoe upper body, wherein the shoe upper body includes PU leather, foam and Lixin cloth arranged in sequence from the outside to the inside, the shoe upper body is provided with multiple groups of stitches, the stitches are used to connect the PU leather and the Lixin cloth, the foam is compressed at the position where the stitches pass through, and the multiple groups of stitches separate the shoe upper body into multiple protective parts.

[0007] By adopting the above technical solution, when making the upper, the less elastic Lixin cloth is placed in a tight state, and then the foam is bonded to the Lixin cloth, and then the PU leather is sutured against the foam, and the foam at the suture position is compressed by the stitching, and at the same time, the PU leather at the remaining positions is adaptively deformed. After the upper is finally formed, the surface of the foam facing the Lixin cloth is set straight, and the surface facing the PU leather is set in an arc shape. That is, the inner surface of the upper body is set to be more comfortable and straight, so that the outer surface of the upper body forms multiple protrusions for protection at the positions of multiple protective parts, so that the upper still has good protection performance when the upper is not set too thick.

[0008] Optionally, a portion of the stitches in the plurality of groups of stitches are arranged at intervals along the circumference of the upper body.

[0009] By adopting the above technical solution, even if a part of the stitching is extended along the width direction of the upper, the upper has better bending performance.

[0010] Optionally, another portion of the stitches are extended along the length direction of the upper body.

[0011] By adopting the above technical solution, on the one hand, the connection between the Lixin cloth, foam and PU leather is strengthened, and on the other hand, the bending performance of the upper is further improved.

[0012] Optionally, the upper body further includes a protective layer, wherein the protective layer is located between the PU leather and the foam, and the protective layer is filled with D30 gel.

[0013] By adopting the above technical solution, D30 gel belongs to the category of "expandable material". It is a single impact-resistant material composed of a "smart molecule" (a combination of viscose liquid and a polymer), which can present two mechanical states under different gravity impacts. Under normal conditions, D30 gel remains relaxed, soft and elastic; when encountering severe impact or extrusion, the molecules immediately lock with each other, quickly tighten and harden to absorb the external force, forming a protective layer; after the external force disappears, the material will return to the original relaxed soft elastic state, with the characteristics of a non-Newtonian fluid. Therefore, by setting a protective layer filled with D30 gel between PU leather and foam, the protective performance of the upper is further improved.

[0014] Optionally, the protective layer includes a plurality of sub-parts, the plurality of sub-parts are independently arranged, and the plurality of sub-parts correspond one-to-one to the plurality of protective parts.

[0015] By adopting the above technical solution, it is convenient to set up the protective layer.

[0016] Optionally, one side of the sub-part is bonded and fixed to the foam, and a gap exists between the other side and the PU leather.

[0017] By adopting the above technical solution, the pulling damage between the PU leather and the protective layer and the foam can be reduced, thereby extending the service life of the shoe upper.

[0018] Optionally, each group of stitches includes two stitches; the PU leather is provided with a plurality of first air holes, and the plurality of first air holes are all located between the two stitches; the Lixin cloth is provided with a plurality of second air holes, and the plurality of second air holes are all located between the two stitches.

[0019] By adopting the above technical solution, the air permeability of the shoe upper is improved.

[0020] On the other hand, a casual shoe disclosed in the present application adopts the following technical solution:

[0021] A leisure shoe comprises an upper and a sole, wherein the upper is connected to the sole, and the upper is a protective upper as described above.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Multiple protrusions for protection are formed on the outer surface of the upper by stitching, so that the upper is relatively light and thin while having good protective performance;

[0024] 2. By setting a protective layer between PU leather and foam and filling the protective layer with D30 gel, the protective performance of the upper is further improved;

[0025] 3. The air permeability of the upper is improved by opening the first air hole in the PU leather and the second air hole in the Lixin cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The embodiments of the present application disclose a protective shoe upper and a casual shoe.

[0035] Example 1

[0036] This embodiment discloses a protective shoe upper

[0037] Reference Figure 1 and Figure 2A protective shoe upper includes a shoe upper body 1, and the shoe upper body 1 includes a PU leather 2, a foam 3 and a Lixin cloth 4 arranged in sequence from the outside to the inside. The shoe upper body 1 is provided with a plurality of sets of stitches 5, and the stitches 5 are used to connect the PU leather 2 and the Lixin cloth 4. The foam 3 is compressed at the position where the stitches 5 pass through, and the plurality of sets of stitches 5 separate the shoe upper body 1 into a plurality of protective parts. When making the shoe upper, the Lixin cloth 4 with less elasticity is put in a tight state, and then the foam 3 is bonded to the Lixin cloth 4, and then the PU leather 2 is abutted against the foam 3 for stitching, and the foam 3 at the stitching position is compressed by the stitches 5, and at the same time, the PU leather 2 at the remaining positions is adaptively deformed. After the shoe upper is finally formed, the surface of the foam 3 facing the Lixin cloth 4 is arranged flat, and the surface facing the PU leather 2 is arranged in an arc shape. That is, the inner surface of the upper body 1 is set to be more comfortable and straight, and the outer surface of the upper body 1 forms multiple protrusions for protection at the positions of multiple protective parts, so that the upper still has good protection performance without being set too thick.

[0038] Specifically, a portion of the plurality of stitches 5 are arranged at intervals along the circumference of the upper body 1, that is, a portion of the stitches 5 are extended along the width direction of the upper, so that the upper has better bending performance. Another portion of the stitches 5 are extended along the length direction of the upper, which on the one hand strengthens the connection between the Lixin cloth 4, the foam 3 and the PU leather 2, and on the other hand further improves the bending performance of the upper.

[0039] In this embodiment, in order to facilitate sewing and ensure the aesthetics of the upper, two groups of stitches 5 arranged along the width direction of the upper are connected at positions of the upper near the shoe holes, that is, two groups of stitches 5 are formed simultaneously during sewing. In other embodiments, the stitches 5 may also be arranged in other ways.

[0040] In this embodiment, each group of sutures 5 includes two sutures 5, which ensures that the sutures 5 have a good pressing effect on the foam 3 and reduces the workload of setting the sutures 5. In other embodiments, each group of sutures 5 may also include other numbers of sutures 5.

[0041] The implementation principle of Example 1 is as follows: when making the upper, the foam 3 is first bonded and fixed to the less elastic Lixin cloth 4, and then the PU leather 2 is sewn to the foam 3 and the Lixin cloth 4, so that the foam 3 is arranged flat on the surface close to the Lixin cloth 4 and is arranged in an arc shape on the surface close to the PU leather 2. Thus, the upper body 1 finally formed is relatively light and thin and has multiple protective parts for protection.

[0042] Example 2

[0043] This embodiment discloses a protective shoe upper.

[0044] Reference Figure 3 and Figure 4The difference between this embodiment and embodiment 1 is that the upper body 1 further includes a protective layer 6, and the protective layer 6 is located between the PU leather 2 and the foam 3. The protective layer 6 includes a plurality of sub-parts 61, and the plurality of sub-parts 61 are independently arranged, and the plurality of sub-parts 61 correspond to the plurality of protective parts one by one.

[0045] The protective layer 6 includes a first layer 62 and a second layer 63. The edge of the first layer 62 is bonded and fixed to the edge of the second layer 63. A filling cavity is defined between the middle of the first layer 62 and the middle of the second layer 63. The filling cavity is filled with D30 gel. D30 gel belongs to the category of "expandable materials". It is a single impact-resistant material composed of a "smart molecule" (a combination of viscose liquid and a polymer), which can present two mechanical states under different gravity impacts. Under normal conditions, D30 gel remains in a relaxed state, soft and elastic; when encountering severe impact or extrusion, the molecules immediately lock with each other, quickly tighten and harden to absorb external forces, and form a protective layer 6; after the external force disappears, the material will return to the original relaxed soft elastic state, with the characteristics of a non-Newtonian fluid. Therefore, by arranging a protective layer 6 filled with D30 gel between the PU leather 2 and the foam 3, the protective performance of the upper is further improved.

[0046] In this embodiment, one side of the plurality of sub-parts 61 is bonded and fixed to the foam 3 to ensure the installation stability of the foam 3. A gap is provided between the other side and the PU leather 2 to reduce the pulling damage between the PU leather 2 and the protective layer 6 and the foam 3, thereby extending the service life of the upper.

[0047] Reference Figure 5 Further, the PU leather 2 is provided with a plurality of first ventilation holes 21, and the plurality of first ventilation holes 21 are all located between a group of two stitches 5. The Lixin cloth 4 is provided with a plurality of second ventilation holes 41, and the plurality of second ventilation holes 41 are all located between a group of two risks, so as to improve the ventilation performance of the upper.

[0048] Example 3

[0049] Reference Figure 6 This embodiment discloses a casual shoe, including an upper 7 and a sole 8, wherein the upper 7 is connected to the sole 8, and the upper 7 is a protective upper as disclosed in Embodiment 1 or Embodiment 2.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
