[0026] like Figure 1-5 As shown, a sole with a free-assembled upper provided by an embodiment of the present invention mainly comprises a sole body 1 , a through hole 2 and a guide hole 3 , and the through hole 2 and the guide hole 3 are integrally formed on the sole body 1 .

[0027] The sole body 1 of this embodiment is generally made of rubber material or EVA material, etc., and can also be a composite material, such as a composite of rubber and EVA, a composite of EVA and TPR, a composite of rubber and TPR, etc., and the sole body 1 is divided into a front part 4, a middle part 5 and a rear part 6 along the long axis direction, and the long axis direction is the length direction of the sole of the foot.

[0028] The perforations 2 of the present embodiment are used for assembly with the upper 10, and are respectively arranged at the front 4 and the rear 6 of the sole body 1. The number of the perforations 2 can be determined according to the connection position that matches the preset shape of the upper 10. If it is a slipper, it can be divided into flip-flops, flip-flops with heels, inverted flops, etc. If it is a flip-flop, only one perforation 2 is needed at the front 4 of the sole body 1. If it is a flip-flop with a heel, only one perforation 2 is needed at the front 4 and the rear 6 of the sole body 1. If it is an inverted flops, the perforations 2 at the front 4 and the rear 6 of the sole body 1 are useless or only the perforations 2 at the front 4 are used. See details in FIG. Figure 3-5 Embodiment 1-3 of the present invention.

[0029] The guide holes 3 of the present embodiment have a preset length and are arranged in pairs at the middle portion 5 of the sole body 1, one end of the paired guide holes 3 faces the front portion 4 and has a first spacing, and the other end of the paired guide holes 3 faces the rear portion 6 and has a second spacing, and the first spacing is smaller than the second spacing; of course, the number of the guide holes 3 can be provided in two pairs as needed, so that adjustment can be achieved for users with different foot widths. Generally, the two groups of paired guide holes 3 are arranged inside and outside, that is, one group of paired guide holes 3 is on the outside, and the other group of paired guide holes 3 is on the inside, and the two groups of paired guide holes 3 are independent of each other. In another embodiment, the guide holes 3 of different groups but located on the same side can be arranged to be connected, and the connecting position can be the end or the middle portion 5, so that the inclined surface can be directly slid from one group of guide holes 3 to the other group of guide holes 3 during assembly without pulling out the guide holes 3, which is more convenient to use.

[0030] In the guide hole 3 of the present embodiment, at least one hole position 7 is arranged along the length direction, and the hole position 7 and the through hole 2 have a mounting structure. In another embodiment, at least two hole positions 7 may also be arranged, which means that at least one gear is adjusted, and the adjacent hole positions 7 generally have a constant spacing, or the spacing is gradually increased, or the spacing is gradually decreased, and there are more options. The mounting structure is a buckle structure. The most commonly used and simple buckle structure is that the pin 11 at the root of the upper 10 is inserted into the through hole 2 or the hole position 7. Since the outer diameter of the end of the pin 11 is larger than the rod, an anti-slip undercut is formed. Specifically, the through hole 2 and the hole position 7 both include an entrance hole 8 and a button hole 9 connected in sequence along the central axis, and the inner diameter of the button hole 9 is larger than the inner diameter of the entrance hole 8. The entrance hole 8 and the button hole 9 of the adjacent hole position 7 are connected through the guide hole 3, and the inner diameter of the button hole 9 is larger than the guide hole 3. After the end of the plug 11 is inserted into the through hole 2 and the hole position 7, it is pulled back and embedded in the buckle hole 9, so that the end of the plug 11 will not exceed the bottom surface of the sole body 1 and affect walking after the user wears the shoes normally. In addition, the length of the plug 11 can be limited, so that the length between the root and the end of the plug 11 is just the depth of the entrance hole 8, and the outer diameter of the root of the plug 11 is larger than the inner diameter of the entrance hole 8, so that after the plug 11 is inserted through the hole 7, the end of the plug 11 can be embedded in the buckle hole 9 without adjustment, so that the inclined surface will not be easily loosened after assembly. Since the upper 10 and the sole body 1 are both made of rubber or EVA and other materials with a certain degree of softness and deformability, the outer diameter of the end of the plug 11 is larger than the inner diameter of the entrance hole 8 and slightly smaller than the inner diameter of the buckle hole 9. During the assembly process, the end of the plug 11 is squeezed and deformed to pass through the entrance hole 8 and enter the buckle hole 9.

[0031] The present invention is designed with a plurality of freely assembled installation structures on the sole body 1, which can be used to freely match with a variety of different styles of uppers 10, ropes, scarves, leather and other materials. Consumers can replace the uppers 10 and soles of the shoes by themselves to change different styles. For example, they can be assembled into different types of shoes such as flip-flops, flip-flops, beach shoes, leather shoes and sandals. Only one pair of soles is needed to assemble and switch multiple forms, reduce the types and number of personal slippers and sandals, and reduce the space occupied by shoes. It is not only environmentally friendly and reduces the cost of buying shoes, but also consumers can experience many non-traditional styles of shoes by assembling them by themselves, which effectively solves the defects of the prior art that the function and style of shoes are single, the cost of personal spare multiple shoes is high, it is not environmentally friendly, and it takes up more space.

[0032] In this embodiment, the guide hole 3 is a straight guide hole 3. In another embodiment, the guide hole 3 is an arc-shaped guide hole 3. The straight-line guide hole 3 brings a more direct and wider span tension adjustment effect, while the arc-shaped guide hole 3 brings a progressive tension adjustment effect. More adaptation options are available according to needs.

[0033] In this embodiment, the paired guide holes 3 have the same preset length, so that the guide holes 3 on both sides have the same adjustment range. Of course, in the case where the paired guide holes 3 have the same preset length, it is only necessary to set the spacing of the hole positions 7 in the inner guide hole 3 to be different from the spacing of the hole positions 7 in the outer guide hole 3, so that adjustment with a larger adaptation range can also be achieved to adapt to different foot shapes. In another embodiment, in order to better adapt to the shape of the foot, the paired guide holes 3 have different preset lengths, generally the guide holes 3 located on the inner side of the foot are short, and the guide holes 3 located on the outer side of the foot are long, so that the inner and outer guide holes 3 have different adjustment ranges to adapt to different foot shapes.

[0034] In the present embodiment, the sole body 1 is a single shoe material. In another embodiment, the sole body 1 at least includes an outsole and a midsole, and the outsole and the midsole are stacked as a whole by hot melting, gluing or buckling. For another example, the sole body 1 includes an outsole, a midsole and an insole. The sole body 1 is selected or assembled according to different use requirements, and the assembly method can be selected as the above-mentioned buckling method in the present application. Generally speaking, the midsole is softer than the outsole, so the buckle hole 9 is at least formed on the outsole to better prevent buckling.

[0035] In this embodiment, the upper 10 is used for assembly with the upper 10, and the upper 10 has at least two roots, and the roots are provided with an assembly structure for assembly with the mounting structure. The assembly structure is the aforementioned plug 11, and the end of the plug 11 has an undercut portion 12 with an outer diameter greater than the rod of the plug 11. Correspondingly, the roots of the upper 10 are assembled with at least two of the through holes 2 of the front part 4 of the sole body 1, the through holes 2 of the rear part 6 of the sole body 1, and the guide holes 3 of the middle part 5 of the sole body 1. As shown in the figure, in some embodiments, the root of the upper 10 is assembled with the through hole 2 of the front part 4 of the sole body 1, the through hole 2 of the rear part 6 of the sole body 1, and the guide hole 3 of the middle part 5 of the sole body 1 respectively; in other embodiments, the root of the upper 10 is assembled with the through hole 2 of the front part 4 of the sole body 1, and the through hole 2 of the rear part 6 of the sole body 1 respectively; in other embodiments, the root of the upper 10 is assembled with the through hole 2 of the front part 4 of the sole body 1, and the guide hole 3 of the middle part 5 of the sole body 1 respectively; in other embodiments, the root of the upper 10 is assembled with the through hole 2 of the rear part 6 of the sole body 1, and the guide hole 3 of the middle part 5 of the sole body 1 respectively; different assemblies of the uppers 10 are achieved through the aforementioned different assembly methods, and different types of shoes are formed.

[0036] In this embodiment, the upper 10 is an injection molded material or a woven material, wherein the woven material can be woven from cloth or bamboo strips, etc. On the basis of the sole body 1 of the above structure, if the woven material is a cloth such as a scarf, it can be directly formed into at least a part of the upper 10 or a part of the upper by a perforated 2 binding method.

[0037] The working principle of the embodiment of the present invention: a sole with a freely assembled upper 10, comprising: a sole body 1, which is divided into a front part 4, a middle part 5 and a rear part 6 in sequence along the long axis direction; perforations 2, which are respectively arranged at the front part 4 and the rear part 6 of the sole body 1; and guide holes 3 with a preset length, which are arranged in pairs at the middle part 5 of the sole body 1, one end of the pair of guide holes 3 faces the front part 4 and has a first spacing, and the other end of the pair of guide holes 3 faces the rear part 6 and has a second spacing, and the first spacing is smaller than the second spacing; wherein, at least two hole positions 7 are arranged on the guide holes 3 in the length direction, and the hole positions 7 and the perforations 2 have a mounting structure. The present invention is designed with a plurality of freely assembled installation structures on the sole body 1, which can be used to freely match with a variety of different styles of uppers 10, ropes, scarves, leather and other materials.
