Description

Technical Field

[0001] The invention relates to the technical field of shoe structure design, and in particular to a protective component and a protective shoe. Background Art

[0002] In daily life, it is common for the sole of the foot to be injured due to falling heavy objects or being stepped on by others. In addition, especially when playing intense sports such as football or basketball, the fierce body collision makes the vulnerable parts such as the sole of the foot or the ankle more vulnerable to impact and cause serious physical injuries. Among them, the main cause of injury is that the protective effect of the upper of the shoe is insufficient, so that the external impact force is directly applied to the sole of the foot or the ankle, causing injury.

[0003] Most of the existing sports shoes only have anti-collision strips at the toe of the shoe upper or at the heel of the shoe upper to provide local protection. However, this arrangement does not cover the area extending from the back of the toe to the ankle surface, which cannot provide comprehensive protection and still has a certain risk of injury. Moreover, the anti-collision strips provided at the toe of the shoe upper or at the heel of the shoe upper are generally only used to disperse the impact force in the horizontal direction to protect the toes and heels from collision, but cannot disperse the impact force in the vertical direction during hitting or collision, and the protection effect is limited. In addition, most of the existing sports shoes with protective components are relatively bulky and inconvenient for exercise, and have poor foot-holding properties and are uncomfortable to wear. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a protective component, which is used to provide comprehensive protection to the instep including the ankle surface, and has a good protective effect; and the protective component is light and easy to install as a whole. A protective shoe is also provided, which uses the above-mentioned protective component as the upper, can provide comprehensive protection for the instep, and has an ideal foot-wrapping property, and is light and suitable for wearing. In addition, a protective shoe is also provided, which, in addition to providing comprehensive protection, can also replace the protective component for recycling, saving manufacturing costs.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A protective component is used to be combined with a sole to form a shoe upper or to be combined with an upper to form a shoe upper protective layer. It includes a surface layer, an inner layer and a protective layer arranged between the two, and the protective layer is injection-molded from ESA material; it is provided with a main body for covering the instep, and wing parts extending on both sides of the main body, and the wing parts are used to cover the ankle surface; and it forms a rib structure, and a plurality of first recessed parts are provided on the upper surface of the area enclosed by the rib structure.

[0007] Preferably, the protective component is provided with a plurality of second recessed portions on the lower surface of the area enclosed by the rib structure thereof, corresponding to the first recessed portions.

[0008] Preferably, the protective component is provided with a plurality of ventilation holes penetrating the upper and lower surfaces in the area enclosed by its rib structure.

[0009] Preferably, the surface layer is a surface film, which is coated on the upper surface of the protective layer.

[0010] Preferably, the inner layer is a double-layer structure.

[0011] Preferably, the side edges of the protective component that are in contact with the ankle surface are rounded.

[0012] A protective shoe, preferably, comprises a sole and an upper formed by the protective component as described above; the upper is provided with a mounting edge extending outward along the bottom of the main body, and the sole is provided with a double-layer wrapping sheet for clamping the mounting edge; the mounting edge is fixed between the double-layer wrapping sheets.

[0013] Preferably, the outer edge of the upper in contact with the sole is subjected to a gradual fading treatment.

[0014] Preferably, it also includes a tension adjustment member; the upper is provided with an adjustment hole near the ankle; one end of the tension adjustment member passes through the adjustment hole, and the other end is fixed to the sole, so as to limit the degree of tightness between the upper and the ankle.

[0015] A protective shoe, preferably, comprises a sole, an upper and the protective component as described above; the upper is fixed to the sole, and the upper is provided with an installation pocket adapted to the protective component; the protective component is inserted into the installation pocket to combine with the upper to form an upper protective layer.

[0016] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The protective component includes a surface layer, an inner layer and a protective layer arranged between the two, and the three are pressed and formed by an integrated foaming technology; and based on the principle of ergonomics, a main body and a wing portion that fit the shape of the instep and the ankle are formed by injection molding, that is, the main body and the wing portion are adapted to be coated on the instep and the ankle surface to provide comprehensive protection for the entire instep extending from the toe to the ankle, and the covering property is good. Among them, the protective layer is injection molded from ESA material, which is a shear thickening material. After being hit, it can quickly harden to withstand the impact of the outside world; and after the external force disappears, the material will return to a soft state, that is, under normal conditions, the material is soft and does not affect wearing, and has a good fit with the protective part, which improves the overall wearing comfort. In addition, since the wing portion extends on both sides of the main body, that is, the two are an integrated structure to form an independently assembled protective component, it is convenient to select the installation method of the protective component according to the actual use requirements. Specifically, the protective component can be combined with the sole to form the upper, and can also be combined with the upper to form the upper protective layer.

[0018] In addition, since the protective structure forms a rib structure and a plurality of first recessed parts are provided on the upper surface of the area enclosed by the rib structure, when each rib is subjected to impact in the vertical direction, its two sides can be deformed toward the first recessed parts provided on the left and right sides respectively, thereby dispersing and absorbing the impact force; and at the same time, the protective layer made of ESA material quickly hardens under the impact force to resist the external impact force, and provides a comprehensive protective effect for the foot surface including the ankle surface covered by it, and the protective effect is ideal, so that the foot surface and the ankle surface are protected from impact and injury. After the external impact force disappears, the rib deformation is restored and the protective layer returns to a soft state, which does not affect comfortable wearing.

[0019] Furthermore, there is no need to fill each first recessed portion with ESA material, which does not affect the final protective effect and can reduce the amount of ESA on the protective layer, thereby reducing the overall weight of the protective component and improving portability, while saving material costs.

[0020] 2. The protective component has a plurality of second recessed parts corresponding to the first recessed parts on the lower surface of the area surrounded by the rib structure, that is, the first recessed parts and the second recessed parts are relatively concave to further reduce the thickness, that is, reduce the ESA material on the protective layer to improve the overall lightness and further reduce the material cost. Specifically, the second recessed parts can be provided corresponding to the parts that are easy to bend, so as to reduce the overall thickness of the parts that are easy to bend to facilitate bending and deformation, that is, reduce the loss of the protective component caused by frequent bending, so as to extend the service life of the protective component.

[0021] 3. The protective component is provided with a number of ventilation holes penetrating the upper and lower surfaces in the area surrounded by the rib structure, which are used for ventilation to prevent the feet from getting stuffy and improve the user experience; specifically, the ventilation holes need to be dispersed to avoid concentrated arrangement resulting in a decrease in local strength. Among them, the ventilation holes can be set in a number of first recessed parts, that is, because the thickness of the first recessed part is relatively thin, the difficulty of punching can be reduced.

[0022] 4. The surface layer is a surface film, which can be attached to the upper surface of the protective layer through lamination, and is used to enhance the tear resistance of the ESA material, avoid cracking of the protective layer, and improve the overall strength of the protective component; and the surface film can play a certain waterproof and dustproof effect to delay the oxidation efficiency of the protective layer and ensure its durability; further, surface films with different patterns can be sprayed on the protective layer to enhance the overall aesthetics and fashion of the protective component, meeting the diverse selection needs of consumers. In addition, the protective component processed by lamination has further reduced the thickness compared with the actual three-layer structure, which is suitable for the needs of lightweight running shoes. Preferably, the tear resistance of the protective layer can also be improved by covering it with transparent mesh.

[0023] 5. The inner layer is a double-layer structure, that is, two layers of lining are provided to enhance the overall strength of the protective component, thereby compensating for the overall strength decreased due to the provision of the first recessed portion and the second recessed portion, so as to ensure that the protective component is stable and durable.

[0024] 6. The side of the protective component that contacts the ankle surface is rounded to prevent the protective layer from hitting the ankle surface when it becomes hard under force, thereby ensuring that wearing comfort is not affected.

[0025] 7. The protective shoe comprises a sole and an upper formed by the protective member as described above. The protective shoe not only has a comprehensive protective effect on the instep including the ankle, but is also light and suitable for wearing, and has an ideal user experience. The upper can be firmly mounted on the sole, and is not easily displaced or detached after installation, so as to ensure the normal use of the protective member. Specifically, the installation edge of the upper is clamped by the double-layer wrapping sheet provided on the sole, and the installation edge is firmly positioned in the double-layer wrapping sheet by sewing or gluing, so as to achieve stable fixing of the upper and the sole.

[0026] 8. The protective component is used to perform a gradual fading treatment on the outer edge that contacts the sole, that is, to form a continuous inclined surface on the outer edge. When the outer edge is hit, the force points can be dispersed into force surfaces to further disperse and absorb the impact force and enhance the overall protective effect; and the outer edge that has undergone the gradual fading treatment can be more closely fixed to the sole and enhance the foot-holding and wrapping properties.

[0027] 9. The protective shoe also includes an elastic adjustment piece, which is convenient for the user to adjust the tightness between the shoe upper and the ankle according to actual use needs, avoid excessive squeezing of the ankle, and adjust the wearing style; at the same time, the elastic adjustment piece plays a limiting role on the protective component, so that it can fit and wrap around the ankle surface, avoiding the protective component from curling up at the corresponding position of the shoe tongue due to frequent contact with the ankle.

[0028] 10. The protective shoe comprises a sole, an upper and the protective component as described above. The protective component is inserted and installed in the installation pocket of the upper to provide a comprehensive protective effect for the foot, that is, the protective component is combined with the upper to form an upper protective layer; in addition, the insertion installation method is convenient for replacing damaged or aged protective components to recycle the upper, further reducing the manufacturing cost. Similarly, the protective component can also be recycled when the upper is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the claims, specification and the above drawings of the present invention, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0042] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0043] See also Figure 1, the present invention provides an embodiment, which is embodiment 1; this embodiment 1 provides a protective component 1, which is used to combine with the sole 2 to form a shoe upper or to combine with the shoe upper to form a shoe upper protective layer, which includes a surface layer, an inner layer and a protective layer arranged between the two, and the three are pressed and formed using an integrated foaming technology; and based on the principle of ergonomics, a main body 11 and a wing 12 that fit the shape of the instep and ankle surface are formed by injection molding, wherein the wing 12 is adapted to the arc of the ankle surface and is mostly U-shaped; that is, the main body 11 and the wing 12 are adapted to cover the instep and ankle surface to provide comprehensive protection to the entire instep extending from the toe to the ankle to avoid injury, and the coverage is good. Preferably, since the parts that are generally hit or impacted are mostly the main body 11, and the impact force on the wing 12 is generally small and easy to disperse; based on the consideration of overall lightness, the thickness of the wing 12 can be reduced to reduce the overall weight of the protective component 1 and improve lightness.

[0044] The protective layer is injection molded from ESA material, which is a shear thickening material that can quickly harden after being hit to withstand external impact force; and after the external force disappears, the material will return to a soft state, that is, under normal circumstances, the material is soft and does not affect wearing, and it fits well with the protected part and is comfortable to wear.

[0045] In the first embodiment, the surface layer is a surface film, which is coated on the upper surface of the protective layer; the surface film is used to enhance the tear resistance of the ESA material, avoid cracking of the protective layer, and improve the overall strength of the protective component; and the surface film can play a certain waterproof and dustproof effect to delay the oxidation efficiency of the protective layer and ensure its durability; further, the surface film of different patterns can be sprayed on the protective layer to enhance the overall aesthetics and fashion of the protective component, meeting the diverse selection needs of consumers. In addition, the protective component 1 coated in the first embodiment of the present invention further reduces the thickness compared with the actual three-layer structure, which is suitable for the needs of running shoes and sports shoes that are light to wear. Preferably, the tear resistance of the protective layer can also be improved by covering with transparent mesh. Since the lining is located on the side of the protective component 1 that is used to contact the instep and ankle surface, a soft, smooth and breathable textile fabric is preferably used, such as a warp-knitted lycra mesh; and the number of layers of the lining can be selected according to the actual use requirements, and a single-layer or double-layer setting can be selected.

[0046] Preferably, based on the consideration of improving the overall strength of the protective component 1, a surface layer and an inner layer may be respectively attached to the upper and lower surfaces of the protective layer, which can also achieve the same protective effect; the surface layer may preferably be made of PP material, but is of course not limited to other materials that can achieve the same anti-tearing effect.

[0047] Among them, since the wing portion 12 extends on both sides of the main body 11, that is, the two are an integrated structure, forming a protective component 1 that can be assembled independently, it is convenient to select the installation method of the protective component 1 according to actual usage requirements. It can be directly installed on the sole 2 as an upper, or it can be installed on the upper as an independent component to cooperate with the upper to form an upper protective layer. Both installation methods can provide protection for the instep of the foot including the ankle.

[0048] like Figure 1-Figure 3 As shown, the protective component 1 is provided with a rib structure 13, and a plurality of first recessed portions 141 are provided on the upper surface within the area enclosed by the rib structure 13, a plurality of second recessed portions 142 are provided on the lower surface of the enclosed area corresponding to the first recessed portions 141, and a plurality of air-permeable through holes 143 penetrating the upper and lower surfaces are also provided in the enclosed area, and each of the first recessed portions 141 and the second recessed portions 142 does not need to be filled with ESA material.

[0049] Preferably, the lower surface can be concavely formed into a plurality of second concave portions 142 corresponding to the first concave portions 141 provided at the bendable part; and a plurality of dispersed first concave portions 141 can be selected to provide ventilation holes 143. The side edge 16 of the protective member 1 that contacts the ankle surface is rounded to prevent the protective layer from hitting the ankle surface when it is hardened by force, thereby ensuring wearing comfort.

[0050] Among them, the thickness is further reduced by the relatively concave first recessed portion 141 and the second recessed portion 142, that is, the material of ESA on the protective layer is reduced to improve the overall lightness and further reduce the material cost; and the first recessed portion 141 and the second recessed portion 142 are correspondingly arranged at the easily bent position, that is, the overall thickness of the corresponding position is reduced to facilitate bending and deformation, reduce the loss of the protective component 1 caused by frequent bending, and extend the service life of the protective component 1. Each breathable through hole 143 is used for ventilation to avoid stuffy feet and improve the user experience; it should be noted that each breathable through hole 143 needs to be dispersed to avoid concentrated arrangement and cause local strength reduction. The breathable through holes 143 can be dispersed in several selected first recessed parts, that is, because the thickness of the first recess 141 is thinner, the difficulty of punching processing can be reduced.

[0051] Furthermore, since the relatively concave first recessed portion 141 and second recessed portion 142 may reduce the overall strength, in the first embodiment, a double-layer lining is provided to enhance the overall strength of the protective component 1, thereby ensuring the overall stability and durability of the protective component 1.

[0052] It should be noted that the protective component 1 provided in the first embodiment can be applied to different types of shoes, including but not limited to: basketball shoes, running shoes, hiking shoes and other types of shoes. Furthermore, since the protective component 1 needs to be attached to the curved surface of the foot and ankle, in the process of mass production, based on the difficulty of the process and the convenience of transportation, the protective component 1 can adopt a split structure, that is, the main body 11 is divided into several pieces with smaller curvatures according to the structure of the main body 11, so that each piece is separately injection molded and then spliced ​​to form an integral protective component 1, and adjacent pieces can be spliced ​​by stitching. Among them, the preferred splitting position is the part that is easy to bend, so that the splicing seam line coincides with the bending line to facilitate bending activities, and it is not easy to form bending marks on the main body 11.

[0053] like Figure 4 As shown, based on the protective component 1 of the first embodiment, the present invention further provides a protective shoe, which includes an upper formed by the protective component 1, a sole 2 and a tension adjustment member 3.

[0054] In the second embodiment, the outer edge 15 of the upper formed by the protective component 1 that contacts the sole 2 is subjected to a gradual fading treatment; that is, the outer edge 15 forms a continuous inclined surface, and when the outer edge 15 is hit, the force points can be dispersed into force surfaces to further disperse and absorb the impact force and enhance the overall protective effect. In addition, the outer edge 15 that has undergone the gradual fading treatment can be more snugly fixed to the sole 2, and has a good foot-wrapping property. In addition, the upper is provided with a mounting edge 17 along the bottom extension of the main body 11, which is used for fitting and mounting with the sole 2; the upper is provided with an adjustment hole 18 near the ankle, which is used for the installation of the tension adjustment member 3.

[0055] The sole 2 is provided with a double-layer wrapping sheet 21 for clamping the mounting edge 17, and the shape of the double-layer wrapping sheet 21 is adapted to the mounting strip 17; that is, the mounting edge 17 is clamped by the double-layer wrapping sheet 21 provided on the sole 2, and then the mounting edge 17 is firmly positioned in the double-layer wrapping sheet 21 by sewing or gluing, so as to achieve stable fixation between the upper and the sole 2.

[0056] Among them, one end of the elastic adjustment member 3 passes through the adjustment hole 18, and the other end is fixed to the sole 2, which is used to limit the degree of closeness between the upper and the ankle; preferably, the elastic adjustment member 3 includes shoelaces, Velcro and / or zippers. In the second embodiment, the elastic adjustment member 3 is Velcro, one end of which is fixed to the sole, and the other end is pasted on the first end after passing through the adjustment hole 18, so that the user can adjust the degree of closeness between the upper and the ankle according to the actual height of the instep, avoid excessive squeezing of the ankle, and adjust the wearing; at the same time, the elastic adjustment member 3 plays a limiting role on the protective member 1, so that the protective member 1 can be wrapped around the ankle surface, avoiding the protective member 1 from being lifted up at the corresponding position of the tongue due to frequent contact with the ankle, ensuring stable wrapping and reducing the risk of injury.

[0057] In the above-mentioned embodiment 2, the protective member 1 is used as the upper to be combined with the sole 2 to form a protective shoe; in another embodiment of the present invention, namely embodiment 3. Embodiment 3 provides a protective shoe in which the protective member 1 is combined with the upper to form an upper protective layer. In embodiment 3, the protective shoe comprises the protective member 1, the sole 2 and the upper as described above; the sole is a conventional sole; the upper is fixed to the sole 2, and an installation pocket adapted to the protective member 1 is provided on the upper for inserting the protective member 1 therein.

[0058] Specifically, the protective component 1 is inserted as a separate component into the installation pocket as a whole. Since the installation pocket is adapted to the shape of the protective component 1, the protective component 1 can fitly cover the inner layer of the installation pocket after installation to form an overall upper protective layer with the upper, thereby providing comprehensive protection for the foot including the ankle.

[0059] Preferably, the installation pocket can be provided with a sealing member at the opening. After the protective member 1 is inserted into the installation pocket, the sealing member closes the opening to limit the protective member 1 from sliding out of the installation pocket, thereby ensuring the stable installation of the protective member 1. In addition, the installation pocket can also be in the form of a mesh bag, which can cover the protective member 1 as a whole to limit its sliding outward. The plug-in installation method provided in this Example 3 can replace the damaged protective member 1 or the upper at any time without disassembly, so as to recycle the intact accessories, further reducing the manufacturing cost of the product.

[0060] In summary, based on the second and third embodiments provided above, the appropriate installation method can be selected according to the actual usage scenarios of different types of shoes. When the protective component 1 stably covers the instep including the ankle, it can achieve an ideal anti-collision effect to protect the entire instep from impact and reduce the risk of injury. Moreover, based on the material characteristics and shape setting adopted by the protective component 1, it has good coverage of the instep and ankle, is comfortable to wear, and is light as a whole and suitable for sports.

[0061] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
