Description

Technical Field

[0001] The invention relates to a shoe structure for improving the support stability of tangential movements. Background Art

[0002] Field sports are all-round intense sports, especially basketball. In order to cope with intense multi-directional sports, a pair of basketball shoes needs to have good durability, support, stability, comfort and good shock absorption. In basketball, the constant starting, sudden stop, jump and rapid left and right movement put higher requirements on the stability of the shoes. Previously, there were cases in basketball games where players were injured due to the bursting of the connection between the upper and the sole. Usually, basketball shoes include a sole and an upper mounted on the sole. In order to improve the stability of the connection between the sole and the upper, the current manufacturers of basketball shoes mainly strictly control the bonding process (installing the sole under the upper), such as controlling the bonding pressure and selecting high-quality glue to ensure the peeling strength and stability of the connection between the sole and the upper. Although mass production can be guaranteed under the control of strict process manufacturing, basketball shoes manufactured using this processing method still have a relatively large risk of bursting during intense competitions.

[0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. Summary of the invention

[0004] The object of the present invention is to provide a shoe structure which is easy to manufacture and can improve the supporting and wrapping performance and supporting stability of tangential movement.

[0007] As a preferred embodiment of the present invention, the first connecting portion is fixed to the sole by gluing, and the second connecting portion is fixed to the upper by gluing or sewing.

[0008] As a preferred embodiment of the present invention, the shoe body is provided with the upper facing upward and the sole facing downward, the sole having an upper surface, a lower surface and a connecting wall formed between the upper surface and the lower surface, the first connecting portion being fixed on the connecting wall of the sole or the lower surface of the sole or the upper surface of the sole, and the second connecting portion being fixed on the upper facing.

[0009] As a preferred embodiment of the present invention, the sole comprises an outsole and a midsole composited on the outsole, and the first connecting portion is arranged between the outsole and the midsole.

[0010] As a preferred embodiment of the present invention, the first connecting portion extends from the outer side of the sole to the inner side and extends to the middle part of the sole.

[0011] As a preferred embodiment of the present invention, the second connecting portion extends backward from the front end portion of the forefoot portion of the upper along the outer side of the forefoot portion and extends to the outer side of the arch portion of the upper, and the first connecting portion extends backward from the front end portion of the forefoot portion of the lower surface of the midsole along the outer side of the forefoot portion and extends to the outer side of the arch portion of the midsole.

[0012] As a further improvement of the present invention, it also includes a reinforcing member, one end of the reinforcing member is connected to the reinforcing sheet, and the other end is connected to the upper or the sole.

[0013] As a preferred embodiment of the present invention, the reinforcing member includes a first connecting section, a second connecting section and a third connecting section, one end of the first connecting section is connected to the reinforcing plate, and the other end extends from the outer side of the upper to the inner side of the upper, and the position where the first connecting section contacts the upper is fixed on the upper, the second connecting section extends from the inner side of the upper to the outer side of the upper, and the second connecting section is arranged between the upper and the sole, or the second connecting section is arranged on the lower surface of the sole, the third connecting section extends from the outer side of the upper to the inner side of the upper, and the position where the third connecting section contacts the upper is fixed on the upper.

[0014] As a preferred embodiment of the present invention, the reinforcing sheet is a fabric sheet, a thermoplastic material or a rubber sheet.

[0015] As a preferred embodiment of the present invention, the sole comprises an outsole and a midsole composited on the outsole, the outsole is made of rubber or a highly wear-resistant composite material, and the midsole is made of a foaming material.

[0017] After adopting the technical solution of the present invention, the sole and the upper are further reinforced by setting a reinforcement plate. According to the characteristics of tangential movement, the outer side of the forefoot part of the shoe body is subjected to concentrated force during tangential movement compared with other parts. The foot has a greater tendency to deviate or detach from the outer side of the shoe body at this point, which may make it difficult for the athlete to perform the best movement, and the risk of detachment between the upper and the sole at this point is also relatively large. Setting the reinforcement plate at this position can improve the wrapping performance of the upper at this point, thereby improving the support stability, so that the foot will not deviate outward too much, and at the same time can effectively reduce the risk of bursting at the connection between the sole and the upper, ensure the support stability of the foot during lateral movement of the foot touching the ground, and improve sports performance and sports protection. Furthermore, in the present invention, the first connection portion of the reinforcing sheet is arranged between the midsole and the outsole, and the upper and lower surfaces of the first connection portion can be respectively combined with the midsole and the outsole to enhance the connection stability of the first connection portion. At the same time, during the movement, the first connection portion is further pressed between the midsole and the outsole by the foot, reducing the risk of the first connection portion and the corresponding position of the upper falling off, and the second connection portion is compounded on the upper to cover the upper, further reducing the risk of the upper and the sole peeling off. Furthermore, by arranging a tension member, the present invention can further enhance the connection strength of the reinforcing sheet and adjust the wrapping property of the upper.

[0040] In order to further explain the technical solution of the present invention, it is described in detail below in conjunction with embodiments.

[0041] Reference Figures 1 to 3 A shoe structure for improving the support stability of tangential movements includes a shoe body, the shoe body includes a sole 10 and an upper 20 mounted on the sole 10, and the upper 20 is mounted on the sole 10 in a conventional manner, such as by bonding with an adhesive or sewing with stitches. The side of the shoe body corresponding to the inner side of the instep is the inner side 17, and the side corresponding to the outer side of the instep is the outer side 16. The position of the shoe body corresponding to the front of the sole of the foot is the forefoot portion 13, the position corresponding to the heel is the heel portion 15, and the position corresponding to the arch of the foot is the arch portion 14. The arch portion 14 is located between the forefoot portion 13 and the heel portion 15. In the present invention, the position corresponding to the upper 20 is also correspondingly referred to as the forefoot portion 13, the arch portion 14, the heel portion 15, the outer side 16 and the inner side 17. At the same time, the position corresponding to the sole 10 is also correspondingly referred to as the forefoot portion 13, the arch portion 14, the heel portion 15, the outer side 16 and the inner side 17, so as to roughly divide the areas of the upper 20 and the sole 10.

[0042] The present invention also includes a reinforcing sheet 30 for reinforcing the connection strength between the outer side 16 of the forefoot portion 13 of the sole 10 and the outer side 16 of the forefoot portion 13 of the upper 20. The reinforcing sheet 30 is in the shape of a sheet to increase the connection surface area between the reinforcing sheet 30 and the upper 20 or the sole 10. The reinforcing sheet 30 is compounded on the outer side 16 of the forefoot portion 13 of the shoe body. The reinforcing sheet 30 has a first connection portion 31 fixed on the sole 10 and a second connection portion 32 fixed on the upper 20. In the area covered by the reinforcing sheet 30 of the present invention, on the one hand, the upper 20 is less likely to deform in the area where the reinforcing sheet 30 is provided, and can provide stable support for the foot. On the other hand, the reinforcing sheet 30 enhances the connection strength between the upper 20 and the sole 10, so that the upper 20 is not easily separated from the sole 20.

[0043] As a preferred embodiment of the present invention, the first connection portion 31 is fixed to the sole 10 by gluing, for example, by gluing with adhesive or by hot pressing, and the second connection portion 32 is fixed to the upper 20 by gluing or sewing. The side of the upper 20 that fits the foot is the inner side, and the other side opposite to the upper side is the outer side, and the first connection portion 31 is compounded on the surface of the upper 20.

[0044] As a preferred embodiment of the present invention, the position where the upper 20 is arranged on the shoe body is the upper position, and the position where the sole 10 is arranged is the lower position. The sole 10 has an upper surface, a lower surface, and a connecting wall formed between the upper surface and the lower surface. The first connecting portion 31 is fixed on the connecting wall of the sole 10. The first connecting portion 31 of the reinforcing sheet 30 spans the junction between the sole 10 and the upper 20 and is compounded on the upper 20 to form a second connecting portion 32, thereby reducing the risk of bursting at the connection between the upper 20 and the sole 10. On this basis, the first connecting portion 31 can be further extended downward along the connecting wall, and after extending a certain length on the lower surface of the sole 10, it is fixed to the lower surface of the sole 10. With this structure, the upper 20 and the sole 10 are fixed in a conventional manner, and the outer side 16 of the forefoot portion 13 of the upper 20 is further fixed to the outer side 16 of the forefoot portion 13 of the sole 10 by the reinforcing sheet 30, which greatly reduces the risk of bursting at the corresponding positions of the upper 20 and the sole 10.

[0045] The present invention may also adopt another fixing method, where the first connecting portion 31 of the reinforcing plate 30 is fixed to the upper surface of the sole 10 , and the second connecting portion 32 is fixed to the upper 20 .

[0046] In another preferred embodiment of the present invention, the sole 10 includes an outsole 12 and a midsole 11 composited on the outsole 12, and the first connection portion 31 is arranged between the outsole 12 and the midsole 11. The first connection portion 31 extends from the outer side 16 of the sole 10 to the inner side 17 and extends to the middle part of the sole 10 (i.e., the middle part of the sole 10 in the inner and outer directions, i.e., the middle part of the shoe body in the left and right directions). In the process of composite the midsole 11 and the outsole 12, the first connection portion 31 of the reinforcing sheet 30 is placed between the midsole 11 and the outsole 12. If necessary, an adhesive can be coated on the upper surface or the lower surface of the first connection portion 31, or a hot melt adhesive film can be arranged, so that the reinforcing sheet 30 is stably clamped between the midsole 11 and the outsole 12. When the upper 20 is installed on the sole 10, the second connection portion 32 is fixed to the upper 20.

[0047] As a preferred embodiment of the present invention, the second connection portion 32 extends backward from the front end of the forefoot portion 13 of the upper 20 (i.e., the front end of the toe portion of the shoe body) along the outer side 16 of the forefoot portion 13, and extends to the outer side 16 of the arch portion 14 of the upper 20, and the first connection portion 31 extends backward from the front end of the forefoot portion 13 of the lower surface of the midsole 11 along the outer side 16 of the forefoot portion 13, and extends to the outer side 16 of the arch portion 14 of the midsole 11. With this structure, the connection strength between the reinforcing sheet 30 and the sole 10 or the upper 20 is enhanced by increasing the contact area between the reinforcing sheet 30 and the sole 10 or the upper 20.

[0048] Reference Figure 4 and Figure 5 On the basis of the first embodiment, a tension member 40 is further added, one end of the tension member 40 is connected to the second connection portion 32 of the reinforcement sheet 30, and the other end can be connected to the inner side 17 of the upper 20 or to the inner side 17 of the sole 10, whereby the tension member 40 applies sufficient tension from the outer side 16 to the inner side 17, which further enhances the stability of the reinforcement sheet 30. In the embodiment, the tension member 40 is a belt-shaped object, and the tension member 40 can be fixed on the upper as a whole. A male Velcro patch can also be provided on the belt-shaped object, and a female Velcro patch can be provided on the reinforcement sheet 30, one end of the belt-shaped object is a fixed end, and the other end is a free end, and the male Velcro patch is provided on the free end, thereby, the male Velcro patch is buckled on different positions of the female Velcro patch, and the belt-shaped object can adjust the wrapping of the upper 20. Refer to Figure 6 and Figure 7Compared with the first embodiment, the third embodiment includes an auxiliary bending groove 33 disposed on the reinforcing sheet 30, and the auxiliary bending groove 33 is opened along the inner side 17 or the outer side 16 of the vamp 20. In the embodiment, the auxiliary bending groove 33 is opened from the inner side 17 to the outer side 16. In the embodiment, there are multiple auxiliary bending grooves 33, and the multiple auxiliary bending grooves 33 are arranged along the front and rear direction of the reinforcing sheet 30. The design of the auxiliary bending grooves 33 meets the bending requirements of the vamp 20 during movement, so that the shoe has both support stability and flexibility. The size and number of the auxiliary bending grooves 33 can be adjusted according to the material of the reinforcing sheet 30.

[0049] Reference Figure 8 and Fig. 9 In the fourth embodiment of the present application, the fourth embodiment adds a tension member 40 on the basis of the third embodiment, and the structure and connection method of the tension member 40 are the same as those of the tension member 40 in the second embodiment.

[0050] Reference Fig.10 and Fig.11 In the fifth embodiment, the tension member 40 is a rope, which is used to replace the belt in the second or fourth embodiment. One end of the rope is fixed to the reinforcing sheet 30, and the other end is fixed to the upper 20 or the inner side 17 of the sole 10. An adjuster can also be provided on the upper 20 or the sole 10, one end of the rope is fixed to the reinforcing sheet 30, and the other end is installed in the adjuster. The adjuster is a common accessory in the field of shoe processing, which is used to retract and position the rope. For example, the wire clamping device introduced in the authorization announcement No. CN104219977B discloses such an adjuster. Sufficient tension can be applied to the rope through the adjuster, so that the reinforcing sheet 30 can be more stably pressed against the upper 20.

[0051] Reference Fig.12 and Fig.13In the sixth embodiment, another tension member 40 is proposed, which can replace the tension member 40 in the second, fourth and fifth embodiments.
