Description

Technical Field

[0001] The utility model relates to the technical field of shoe body design, in particular to a carbon plate detachable insole and sports shoes. Background Art

[0002] Currently, most carbon plate running shoes and carbon plate cross-country running shoes on the market have the carbon plate placed in the front between the two midsoles or sandwiched between the outsole and the midsole. The carbon plate is not removable, resulting in a limited usage scenario. Some removable carbon plates are directly placed under the insole. Although simple to implement, the carbon plate is not well fixed in the shoe due to the thin insole, which fails to fully utilize the carbon plate's function and the user experience is poor. The gimmick is more than practical. As a result, it is impossible to achieve the true boost and stability experience brought by carbon plate running shoes, and it is more of a conceptual function. For example, the patent application number 202321645730 disclosed in the prior art discloses a high-elasticity, anti-sprain, and speed-increasing functional insole, which has corresponding grooves on the top and bottom sides of the insole, respectively, so that the support plate (i.e., the carbon plate) can be placed in the corresponding grooves. The support plate is a detachable structure and can be replaced at any time, thereby further improving the service life of the insole and the convenience of use. Although the support plate in this patent realizes the positioning connection between it and the insole through a clip-on structure, during the placement of the insole into the shoe, the support plate is very easy to fall off from the groove on the bottom side of the insole, which reduces the user experience. Summary of the Invention

[0003] The carbon plate detachable insole and sports shoes designed in the present invention can at least partially solve the above problems.

[0004] The purpose of the present utility model is to provide a carbon plate detachable insole, comprising an insole body and a carbon fiber plate, a receiving groove being formed on the bottom side surface of the insole body, the carbon fiber plate being capable of being detachably assembled in the receiving groove, a locking column being formed on the bottom wall of the receiving groove, the locking column extending from the bottom wall of the receiving groove to one side of the groove opening by a preset height, and the cross-sectional area of ​​the locking column gradually increasing in a direction away from the bottom wall of the groove, the carbon fiber plate having a locking hole, and when the carbon fiber plate is assembled in the receiving groove, the locking column is inserted into the locking hole and the free end of the locking column is stopped on the side surface of the carbon fiber plate away from the bottom wall of the groove.

[0005] In some embodiments, the locking hole has an assembly groove extending toward and passing through one side of the thickness side wall of the carbon fiber plate, and the minimum groove width of the assembly groove is between the maximum width and the minimum width of the locking column.

[0006] In some embodiments, the notch of the assembly slot is in an outwardly expanding trumpet-shaped shape.

[0007] In some embodiments, the cross-section of the locking column is oval-shaped, and the extension direction of the long axis of the oval circle is parallel to the width direction of the insole body, and the extension direction of the short axis is parallel to the length direction of the insole body. The hole shape of the locking hole is oval-shaped, and with the orientation of the carbon fiber plate assembled in the accommodating groove as a reference, the extension direction of the long axis of the oval circle is parallel to the length direction of the insole body, and the extension direction of the short axis is parallel to the width direction of the insole body, and the minimum short axis of the locking column is equal to the short axis of the locking hole.

[0008] In some embodiments, on the same cross section, the difference between the major axis and the minor axis of the oval shape of the locking post is 1 mm.

[0009] In some embodiments, the long axis of the free end face of the locking column is 15 mm and the short axis is 14 mm, the long axis of the connection end face of the locking column and the bottom wall of the groove is 14 mm and the short axis is 13 mm; and / or, the preset height of the locking column is 2 mm.

[0010] In some embodiments, with the orientation of the insole body in use as a reference, the locking column is located in the rear area of ​​the accommodating groove, and a limiting ridge extending toward the rear area is formed in the front area of ​​the accommodating groove. The carbon fiber plate also has a card slot. When the carbon fiber plate is assembled in the accommodating groove, the limiting ridge is engaged in the card slot.

[0011] In some embodiments, the free end surface of the limiting ridge has an anti-slip flange, and when the carbon fiber plate is assembled in the accommodating groove, the anti-slip flange stops on the side surface of the carbon fiber plate away from the bottom wall of the groove.

[0012] The utility model also provides a sports shoe, comprising an outsole, a midsole and an insole stacked in sequence from bottom to top, wherein the insole is the above-mentioned detachable carbon plate insole.

[0013] In some embodiments, when the insole is placed on the midsole, the sidewalls of the outsole protrude beyond the top side of the insole.

[0014] The utility model discloses a detachable carbon plate insole and sports shoes:

[0015] Since the cross-sectional area of ​​the locking column gradually increases in the direction away from the bottom wall of the groove, when the carbon fiber plate is assembled in the accommodating groove, the locking column not only limits the relative position of the carbon fiber plate with respect to the accommodating groove, but can also form a stop lock on the side surface of the carbon fiber plate away from the bottom wall of the groove through its free end with a larger cross-sectional area, thereby preventing the carbon fiber plate from falling out of the accommodating groove when the insole body and the carbon fiber plate are placed in the shoe in the assembled state, thereby improving the user experience.

[0022] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. In the figures, regions and layer thicknesses are exaggerated for clarity. Identical reference numerals in the figures denote identical or similar structures, and thus detailed descriptions thereof will be omitted.

[0023] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0024] The following examples illustrate the detachable carbon plate insoles and sports shoes of the present invention. These examples are only a portion of the embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 4 According to an embodiment of the present invention, a carbon plate detachable insole is provided, comprising an insole body 1 and a carbon fiber plate 2 (also known as a carbon plate). A receiving groove 11 is formed on the bottom side of the insole body 1. The bottom side is based on the orientation of the insole in use. The carbon fiber plate 2 can be detachably assembled in the receiving groove 11. It can be understood that the shape of the carbon fiber plate 2 and the shape of the receiving groove 11 are adapted to match each other. A locking column 111 is formed on the bottom wall of the receiving groove 11. The locking column 111 extends from the bottom wall of the receiving groove 11 to one side of the notch by a preset height, and the cross-sectional area of ​​the locking column 111 is along the groove away from the groove. The direction of the bottom wall gradually increases, and the carbon fiber plate 2 has a locking hole 21. When the carbon fiber plate 2 is assembled in the accommodating groove 11, the locking column 111 is inserted into the locking hole 21 and the free end of the locking column 111 stops on the side of the carbon fiber plate 2 away from the bottom wall of the groove. Specifically, taking the example of each cross section of the locking column 111 being circular, the longitudinal section of the locking column 111 is a truncated cone. At this time, the aperture of the locking hole 21 is between the top diameter and the bottom diameter of the aforementioned truncated cone, so that after the locking column 111 and the locking hole 21 are assembled, the large diameter surface of the locking column 111 can stop on the outer side of the carbon fiber plate 2.

[0026] In this technical solution, since the cross-sectional area of ​​the locking column 111 gradually increases in the direction away from the bottom wall of the groove, when the carbon fiber plate 2 is assembled in the accommodating groove 11, the locking column 111 not only limits the relative position of the carbon fiber plate 2 relative to the accommodating groove 11, but can also form a stop lock on the side of the carbon fiber plate 2 away from the bottom wall of the groove through its free end with a larger cross-sectional area, thereby preventing the carbon fiber plate 2 from falling out of the accommodating groove 11 when the insole body 1 and the carbon fiber plate 2 are placed in the shoe in the assembled state, thereby improving the user experience.

[0027] The carbon fiber plate 2 is a multi-layer stacked structure. It is matched with resin according to the designed angle and molded and cooled to achieve the required hardness and toughness. At the same time, the carbon fiber content is controlled at 65-72%. The surface of the carbon fiber plate 2 should be smooth and free of burrs, and the corners should be rounded to avoid hurting the palm during disassembly and assembly.

[0028] The insole body 1 is adjusted according to the designed thickness so that the sole of the foot does not feel the foreign body sensation of the carbon fiber plate 2. At the same time, the carbon fiber plate 2 should exert its unique rebound thrust. The shape design of the accommodating groove 11 on the lower side of the insole body 1 should be consistent with the shape of the carbon fiber plate 2. It can be seamlessly assembled during use and can be easily disassembled when the carbon fiber plate 2 is not used in daily commuting. The upper side design of the insole body 1 is similar to that of ordinary insoles, and the hardness is controlled within 40 degrees to ensure the foot feel while using a certain support force.

[0029] In some embodiments, see Figure 3 As shown, the locking hole 21 has an assembly groove 211 extending toward and through one side of the thickness side wall of the carbon fiber plate 2. The minimum groove width of the assembly groove 211 is between the maximum width and the minimum width of the locking column 111, so as to ensure that the locking column 111 can be inserted into the locking hole 21 from the side of the carbon fiber plate 2, thereby facilitating the user to lock the carbon fiber plate 2 and the insole body 1 into a whole. Figure 3 As shown, the notch of the assembly slot 211 is in an outwardly expanding trumpet-shaped shape. The notch of the assembly slot 211 is designed in an outwardly expanding trumpet-shaped shape to facilitate guiding the locking column 111 into the locking hole 21 .

[0030] In some embodiments, in conjunction with Figures 1 to 3As shown, the cross-section of the locking column 111 is an oval circle, and the extension direction of the long axis of the oval circle is parallel to the width direction of the insole body 1, and the extension direction of the short axis is parallel to the length direction of the insole body 1. The hole shape of the locking hole 21 is an oval circle, and with the orientation of the carbon fiber plate 2 assembled in the accommodating groove 11 as a reference, the extension direction of the long axis of the oval circle is parallel to the length direction of the insole body 1, and the extension direction of the short axis is parallel to the width direction of the insole body 1, and the minimum short axis of the locking column 111 is equal to the short axis of the locking hole 21.

[0031] In this technical solution, the cross-sections of the locking column 111 and the locking hole 21 are both designed to be oval-shaped, and the major axis and minor axis of each oval shape are necessarily limited. Specifically, when the carbon fiber plate 2 is assembled in the accommodating groove 11, the minor axes of the locking column 111 and the locking hole 21 coincide with each other, so that a reliable locking connection between the locking column 111 and the locking hole 21 can be achieved in a rotational manner.

[0032] In some embodiments, on the same cross section, the difference between the major axis and the minor axis of the oval shape of the locking post 111 is 1 mm.

[0033] See Figure 1 As shown, in a specific embodiment, the long axis of the free end surface of the locking post 111 is 15 mm and the short axis is 14 mm. The long axis of the end surface of the connecting end of the locking post 111 and the bottom wall of the groove is 14 mm and the short axis is 13 mm. Correspondingly, the short axis of the locking hole 21 is 13 mm. Since an interference fit is formed between the short axis of the locking hole 21 and a long axis of the locking post 111 when the carbon fiber plate 2 is assembled in the accommodating groove 11, the connection reliability between the carbon fiber plate 2 and the insole body 1 can be further improved. In a specific embodiment, the material of the insole body 1 is a material with a certain degree of elasticity.

[0034] In a specific embodiment, the preset height of the locking column 111 is 2 mm, which ensures that it can reliably lock the carbon fiber plate 2 without causing a large bulge or abnormal feeling on the sole of the user's foot.

[0035] In some embodiments, with the orientation of the insole body 1 in use as a reference, the locking column 111 is located in the rear area of ​​the accommodating groove 11, and a limiting ridge 112 extending toward the rear area is also formed in the front area of ​​the accommodating groove 11. The carbon fiber plate 2 also has a card slot 22. When the carbon fiber plate 2 is assembled in the accommodating groove 11, the limiting ridge 112 is engaged in the card slot 22.

[0036] In this technical solution, the rear side and the front side of the carbon fiber plate 2 form a reliable locking connection with the insole body 1 through the locking column 111 and the locking hole 21, the limiting protrusion 112 and the card slot 22, respectively, to further prevent the carbon fiber plate 2 from falling off from the accommodating groove 11 when the insole is placed in the shoe after the carbon plate is assembled.

[0037] As a more preferred embodiment, the free end face of the limiting ridge 112 (based on the specific usage orientation, that is, the bottom side face of the limiting ridge 112) has an anti-slip flange 1121. When the carbon fiber plate 2 is assembled in the accommodating groove 11, the anti-slip flange 1121 stops on the side face of the carbon fiber plate 2 away from the bottom wall of the groove. The anti-slip flange 1121 objectively forms an inverted hook structure on the free end face of the limiting ridge 112, thereby forming a reliable locking position for the front side of the carbon fiber plate 2.

[0038] According to an embodiment of the present invention, a sports shoe is also provided, comprising an outsole 101, a midsole 102 and an insole stacked in sequence from bottom to top. The insole is the above-mentioned detachable carbon plate insole. It can be understood that the upper area of ​​the insole is the upper 103.

[0039] In some embodiments, when the insole is placed on the midsole 102, the sidewalls of the outsole 101 protrude from the top side of the insole to match the thickness difference of the insole, making it more stable and comfortable.

[0040] Upper 103 is a commuting outdoor sports shoe upper. It is designed to be fully bonded to the outsole according to the cold-bonding shoe process. At the same time, the matching last should take into account the thickness of the insole to ensure that the entire shoe remains comfortable during wearing and can be used in multiple functions and scenarios.

[0041] In a specific embodiment, the thickness of the carbon fiber plate 2 is consistent with that of the accommodating groove 11 of the insole body 1, and the heel shape is the same width when the two are at 90 degrees. After the carbon plate is rotated 90 degrees clockwise, the carbon fiber plate 2 and the insole body 1 are stuck with each other and the shape of the carbon fiber plate 2 is completely locked with the accommodating groove 11. The forefoot (that is, the front area) of the insole is provided with a convex groove (that is, the aforementioned limiting convex strip 112) which is locked with the notch of the carbon fiber plate 2 (that is, the aforementioned locking groove 22). The front and rear ends of the carbon fiber plate 2 are both stuck under the insole body 1, and it is stuffed into the shoe body and compacted so that it completely follows the movement of the sole of the foot, playing a role in tortuous rebound and boosting after the carbon fiber plate 2 is bent. The carbon plate itself has a certain hardness and toughness, and also provides stability and torsion resistance for complex terrain.

[0042] During daily wear, remove the insole, slightly bend the insole in the opposite direction, and easily pull out the carbon fiber plate 2 at the forefoot position with the same hand. Then, rotate it 90 degrees counterclockwise around the heel locking point (i.e., the aforementioned locking post 111) to release the heel carbon fiber plate 2 from the insole body 1. Remove the carbon fiber plate 2 and reinsert it into the insole to compact it. The flexible removal of the carbon fiber plate 2 from the insole body 1 allows for different usage scenarios, allowing one shoe to be used in multiple scenarios, combining functionality and comfort with ease of operation and enhanced practicality.

[0043] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
