Description

Technical Field

[0001] The utility model relates to the field of sole structures, in particular to a stitched shoe outsole. Background Art

[0002] Shoes are an important part of people's daily life. Traditional shoes are composed of uppers, outsoles, midsoles, and heels. The outsoles are bonded to the uppers by gluing, and the midsoles are placed on top of the outsoles by gluing, sewing, or directly placing them. In the manual production process, adhesives pose a great threat to workers' health and also pose a great harm to the environment. Therefore, the gluing method has been gradually eliminated and replaced by the sewing method, which connects the uppers to the sewing grooves on the outsoles through sutures. However, the sewing method currently has some disadvantages. For example, in actual use, corrosive substances such as rainwater and mud easily adhere to the sutures, which reduces the toughness and strength of the sutures. During exercise, the sutures are easily broken due to the friction between the sutures and the suture holes, causing the uppers to partially separate from the outsoles, which not only affects the aesthetics of the shoes, but also reduces the comfort when wearing them. Therefore, it is necessary to produce a sewn outsole to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of the utility model is to provide a stitched shoe outsole to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] A sewn shoe outsole comprises a sole plate, a sewing ring and a dustproof ring. The lower end of the sewing ring is fixed to the upper end surface of the sole plate, the sewing ring surrounds the edge of the sole plate, the inner side of the sewing ring is provided with an inner sewing groove, the outer side of the sewing ring is provided with an outer sewing groove, the lower end of the dustproof ring is fixed to the upper end surface of the sole plate, the dustproof ring surrounds the outer circumference of the sewing ring, the inner lower side of the outer sewing groove is provided with a sewing working area, and the upper end surface of the dustproof ring is higher than the sewing working area.

[0006] Further description of the utility model: the upper end of the dustproof ring is inclined toward the inner side of the sole plate.

[0024] The present invention will be further described below with reference to the following embodiments and accompanying drawings:

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, a stitched shoe outsole includes a sole plate 01, a stitching ring 02 and a dustproof ring 03. The lower end of the stitching ring 02 is fixed to the upper end surface of the sole plate 01, and the stitching ring 02 surrounds the edge of the sole plate 01. The inner side of the stitching ring 02 is provided with an inner stitching groove 021, and the outer side of the stitching ring 02 is provided with an outer stitching groove 022. The lower end of the dustproof ring 03 is fixed to the upper end surface of the sole plate 01, and the dustproof ring 03 surrounds the outer circumference of the stitching ring 02. The inner lower side of the outer stitching groove 022 is provided with a stitching working area 0221, and the upper end surface of the dustproof ring 03 is higher than the stitching working area 0221.

[0027] The lower end of the upper 05 corresponds to the sewing work area 0221 and is sewn to the sewing ring 02 through sewing thread. The sewing needle shuttles the sewing thread back and forth between the inner sewing groove 021 and the outer sewing groove 022 to form a sewing hole. By arranging a dustproof ring 03 on the outer periphery of the sewing ring 02, it can prevent corrosive substances such as rainwater and mud from contacting the sewing thread during the use of the shoe, avoid the sewing thread from being corroded and causing the toughness and strength to decrease, and make the upper 05 not easy to separate from the sole plate 01, thereby ensuring the beauty of the shoe and the comfort when wearing the shoe; on the other hand, it can also effectively prevent dirty water from soaking the bottom of the upper 05, thereby preventing dirty water from spreading upward from the upper 05 and spreading to the inside of the shoe through the sewing hole, ensuring the cleanliness of the upper 05 and the dryness and comfort inside the shoe.

[0028] The sole plate 01 is provided with a wear-resistant portion 011 protruding outward from the dust ring 03. By providing the wear-resistant portion 011, the dust ring 03 can be protected. In some designs where the upper 05 protrudes outward more, the upper 05 can also be protected.

[0029] The protruding length of the wear-resistant portion 011 relative to the lower end of the dust ring 03 is not less than 5 mm, as shown by the length X in the figure, which can effectively ensure that the dust ring 03 and the shoe upper 05 are not worn.

[0030] This design also includes a heel 04, which is fixed to the rear end of the sole plate 01. The sole plate 01, the sewing ring 02, the dust ring 03, and the heel 04 are integrated into one piece. This facilitates the one-time molding of the sole plate 01, the sewing ring 02, the dust ring 03, and the heel 04, reducing assembly steps and manufacturing costs.

[0031] The rear side of the upper end surface of the sole plate 01 is evenly provided with a plurality of first buffer grooves 012, which extend downward into the heel 04. This can reduce the weight of the heel 04 and increase its softness, thereby improving the comfort when wearing.

[0032] The upper end surface of the sole plate 01 is provided with a wavy second buffer groove 013, which is evenly arranged on the front side of the heel 04. This can reduce the weight of the sole and increase the softness, thereby improving the comfort when wearing.

[0033] Example 2:

[0034] like Figure 5 As shown, this embodiment is basically the same as the first embodiment, except that the upper end of the dust ring 03 is tilted toward the inner side of the sole plate 01. The angle between the upper end of the dust ring 03 and the vertical plane is 15° to 30°, as shown by angle Y in the figure.

[0035] After the upper 05 is sewn, the sewing ring 02 and the dustproof ring 03 are on both sides of the upper 05. A gap is likely to appear between the top of the dustproof ring 03 and the upper 05. Therefore, the dustproof ring 03 is set to a certain degree of inclination, so that the top of the dustproof ring 03 can press the upper 05 inward, avoiding the formation of a gap between the top of the dustproof ring 03 and the upper 05, thereby preventing dust and other particulate foreign matter from entering the bottom of the sewing ring 02 through the gap.

[0036] Example 3:

[0037] like Figure 6 As shown, this embodiment has essentially the same structure as the second embodiment, differing in that the upper end surface of the dust ring 03 is higher than the upper end surface of the sewing ring 02. Conventional vamps 05 are prone to collapsing outwards under the influence of gravity, making the vamp 05 appear wider and bulky, affecting the aesthetics. Furthermore, the bottom of the vamp 05 does not fit the foot well, affecting comfort. However, by setting the upper end surface of the dust ring 03 higher than the upper end surface of the sewing ring 02, the vamp 05 can be corrected to fit inwards, thereby making it fit the foot better and not appear bulky.

[0038] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
