Description

Technical Field

[0001] The utility model relates to the technical field of shoe soles, and particularly relates to a shock-absorbing shoe sole and a shoe with upper and lower layers shearing. Background Art

[0002] For existing shoes with shock-absorbing functions on the market, improvements are generally made in the material and structure of the shoe sole. For example, in terms of the shoe sole material, foamed thermoplastic polyurethane material with better shock-absorbing effect is adopted; or in terms of the shoe sole structure, structures such as air cushions and shock-absorbing columns are designed. Among them, compared with the improvement of the shoe sole material, the improvement of the shoe sole structure can more directly improve the shock-absorbing performance of the shoe sole. However, the current shock-absorbing shoe soles have problems of relatively hard overall wearing feeling and low comfort. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems in the background art, and provide a shock-absorbing shoe sole and a shoe with upper and lower layers shearing, which can improve the wearing comfort.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Technical solution one: A shock-absorbing shoe sole with upper and lower layers shearing. On both the inner side and the outer side in the width direction of the shoe sole, first grooves are respectively arranged along the length direction, and a second groove is arranged along the length direction at the middle position in the width direction of its bottom surface; in the length direction of the shoe sole, the width of the notch of the first groove has a change trend consistent with the thickness of the shoe sole, and the width of the notch of the second groove has a change trend consistent with the width of the shoe sole.

[0006] Technical solution two based on technical solution one: The depth of the first groove is the largest at the middle waist position of the shoe sole.

[0007] Technical solution three based on technical solution one: At the heel position of the shoe sole, the depth of the first groove on the inner side is less than the depth of the first groove on the outer side.

[0008] Technical solution four based on technical solution one: A third groove is arranged along the width direction at the rear end side in the length direction of the shoe sole, and both ends of the third groove are respectively connected to the rear ends of the two first grooves on the inner side and the outer side of the shoe sole.

[0009] Technical solution five based on technical solution one: The upper and lower side walls of the first groove extend obliquely towards each other from the notch position and are butted at the middle line position corresponding to the notch.

[0010] Technical solution six based on technical solution five: The shape of the docking line of the upper and lower side walls of the first groove in the projection plane perpendicular to the width direction is a broken line, and the upper and lower edges of the notch of the first groove are curves that are smoothly transitioned and relatively parallel along the length direction.

[0011] Technical solution seven based on technical solution six: At the vertex position of the broken line formed by the docking line of the upper and lower side walls of the first groove, on the side wall of the first groove with a smaller included angle corresponding to this vertex, a fourth groove is formed that connects to this vertex and extends to the notch edge of the first groove, and a fifth groove that is connected to the fourth groove and extends along the thickness direction is formed on the inner side and / or outer side of the sole.

[0012] Technical solution eight based on technical solution one: The bottom surface of the heel position of the sole is provided with a sixth groove whose depth is greater than that of the second groove, and the sixth groove extends from the outer side of the sole to the middle in the width direction of the sole and then extends backward to the rear side surface of the sole.

[0013] Technical solution nine based on technical solution one: The bottom surface of the heel position of the sole is provided with a sixth groove whose depth is greater than that of the second groove, and the sixth groove extends from the outer side of the sole to the inner side and then bends backward in the middle of the width direction of the sole.

[0014] In addition, the present utility model also provides technical solution ten: A shoe, which includes a shock-absorbing sole with upper and lower layered shearing as described in any one of technical solutions one to nine.

[0015] As can be seen from the above description of the present utility model, compared with the prior art, the present utility model has the following beneficial effects:

[0016] Technical solution one provides a shock-absorbing sole with upper and lower stratified shearing. The sole is provided with a first groove on the inner and outer sides in the width direction and a second groove is arranged at the middle position of the bottom surface. Both the first groove and the second groove extend along the length direction. Among them, the first groove divides the shock-absorbing sole into upper and lower parts. When the user walks, runs and other actions with this sole, the lower part of the sole will first contact the ground. The friction between the bottom surface of the sole and the ground makes the lower part of the sole relatively fixed to the ground compared with its upper part. Since the first groove weakens the connection between the upper part and the lower part of the sole, the upper part of the sole can translate forward relative to its lower part. At the same time, when the sole is subjected to a vertical pressure, the second groove arranged on the bottom surface of the sole will make the whole sole easier to be flattened. The bottom of the second groove will be closer to the ground or directly contact the ground. By the deformation of the second groove, the edges of the first groove will approach each other, thereby further increasing the relative sliding between the upper part and the lower part of the sole. At the same time, the upper part and the lower part of the sole will also approach each other in the up and down direction, so as to improve the overall shock-absorbing performance of the sole through the stratified shearing of the upper part and the lower part of the sole.

[0017] Among them, the notch widths of the first groove and the second groove are made to be consistent with the changing trends of the thickness and width of the sole, so that the degree of change in the relative slip between the upper part and the lower part of the sole can be kept consistent at each position in the length direction of the sole, avoiding the situation that the slip degree between the upper part and the lower part of the sole is too small due to the insufficient notch width of the first groove at the thicker position of the sole, and at the same time, it can also avoid the situation that the slip degree between the upper part and the lower part of the sole is too large due to the too large notch width of the first groove at the thinner position of the sole, and the overall deformation of the sole and the shearing shock-absorbing effect between the upper part and the lower part are better.

[0018] At the same time, the relative slip between the upper part and the lower part of the sole has a strong correlation with the notch width and notch depth of the second groove. The second groove should have a larger notch width and a deeper notch depth, so that the sole can be more easily flattened when subjected to a vertical pressure, thereby increasing the relative slip between the upper part and the lower part of the sole. However, the notch depth of the second groove should be kept within an appropriate range to ensure that the sole has good support performance.

[0019] In technical solution two, the notch depth of the first groove is the largest at the midriff position of the sole. Correspondingly, the notch depth of the first groove is smaller at the forefoot position and the heel position of the sole compared with the midriff position. With such a setting, the upper part and the lower part of the sole have a larger deformation space at the midriff position. When the sole is stepped on and bent, the upper part and the lower part of the sole can still have relative slip.

[0020] In Technical Solution 3, at the heel position of the sole, the depth of the first groove on the inner side is less than that on the outer side. The shallower depth of the groove on the inner side can improve the support performance of the heel of the sole, while the deeper depth of the groove on the outer side can improve the slippage degree between the upper part and the lower part of the sole, enhancing the shock absorption effect.

[0021] In Technical Solution 4, a third groove is provided at the end face of the heel of the sole. The third groove connects the first grooves on both sides, thereby forming a continuous groove structure on the side part of the sole. The sole is divided into an upper part and a lower part from the heel to the forefoot position, reducing the pulling force of the heel end face on the upper part and the lower part of the sole, and making the relative slippage between the two more significant.

[0022] In Technical Solution 5, the upper and lower groove walls of the first groove extend obliquely relative to each other and butt at the midline position corresponding to the groove opening, enabling a certain degree of connection between the upper part and the lower part of the sole, ensuring the overall support performance of the sole. At the same time, the upper part and the lower part of the sole can produce relative slippage within a certain range, improving the shock absorption performance of the sole.

[0023] In Technical Solution 6, the docking line is designed in a zigzag shape, and the edge of the groove opening of the first groove is designed as a smoothly transitioning parallel curve. When the sole is stepped on and the upper part and the lower part of the sole undergo relative slippage, the zigzag docking line can cause the upper part and the lower part of the sole to produce slippage deformation within the preset range at the position of the first groove. The upper groove wall and the lower groove wall of the first groove will push against each other, preventing the upper part and the lower part from slipping too much. At the same time, the resistance received by the upper part at the first groove during slippage will be transmitted to the user's foot, thereby improving the shock absorption performance of the sole.

[0024] In Technical Solution 7, a fourth groove is provided on the groove wall of the first groove corresponding to the vertex of the zigzag line, and a fifth groove is provided on the side of the sole corresponding to the fourth groove. The fourth groove and the fifth groove can improve the deformation degree of the upper part and the lower part of the sole in the length direction, enhancing the shock absorption effect.

[0025] In Technical Solution 8, a sixth groove is provided on the bottom surface of the sole. The sixth groove is deeper and extends from the outer side of the sole to the rear side of the sole. When the sole is stepped on, the degree of deformation is higher, thereby increasing the closing degree of the first groove and the relative slippage degree between the upper part and the lower part of the sole, further improving the shock absorption performance of the sole.

[0026] In technical solution nine, a sixth groove is provided on the bottom surface of the sole. The sixth groove is deeper and extends from the outer side surface to the inner side surface of the sole and bends backward at the middle position. When the sole is stepped on, the degree of deformation is higher, thereby improving the degree of closure of the first groove and the relative slippage degree of the upper and lower parts of the sole, further improving the shock absorption performance of the sole.

[0027] Technical solution ten provides a shoe comprising the above-mentioned upper and lower layered sheared shock-absorbing sole, which can provide the user with sufficient shock-absorbing performance through the relative sliding of the upper and lower parts of the sole.

[0051] Embodiment 1

[0052] Referring to Figure 1 , Embodiment 1 of the present utility model provides a shoe, which includes a shoe upper and a sole 10 compounded with the shoe upper. The sole 10 is a shock-absorbing sole 10 with upper and lower layers sheared provided in this embodiment.

[0053] Among them, referring to Figure 1 , the shock-absorbing sole 10 with upper and lower layers sheared provided in this embodiment includes a sole 10 member formed by processes such as foaming or thermoplastic molding. Based on the understanding of the structure of the conventional sole 10 by those skilled in the art, it is known that the sole 10 has a width direction and a length direction. The two side surfaces in the width direction of the sole 10 are respectively an inner side surface 11 and an outer side surface 12. At the same time, the rear end position in the length direction of the sole 10 is the rear end side surface of the sole 10. It should be understood that at the front end position in the length direction of the sole 10, the sole 10 has a shape with gradually decreasing thickness, so a side surface is not defined at the front end position of the sole 10.

[0054] At the same time, those skilled in the art are familiar with that the sole 10 can be divided into a forefoot position 16, a midfoot position 15 and a heel position 14 in the length direction according to the corresponding relationship between the sole 10 and the foot. It should be understood that the forefoot position 16, the midfoot position 15 and the heel position 14 here are only rough divisions of different parts of the sole 10, and there is no strict dividing boundary between the three.

[0055] In the sole 10 provided in this embodiment, first grooves 21 are provided along the length direction on the inner side surface 11 and the outer side surface 12 in the width direction of the sole 10. The shape of the first grooves 21 can be obtained by Figure 1 observation, but Figure 1 it is only the outer view of the sole 10, and a first groove 21 is also provided on the inner side surface 11 of the sole 10 not shown. At the same time, referring to Figure 2 , a second groove 22 is provided along the length direction at the middle position in the width direction of the bottom surface 13 of the sole 10.

[0056] Referring toFigure 1 , the notch edges of the first groove 21 are the first edge 211 and the second edge 212 respectively; refer to Figure 2 , the notch edges of the second groove 22 are the third edge 221 and the fourth edge 222 respectively. The distance between the first edge 211 and the second edge 212 is the notch width of the first groove 21, and the distances from the first edge 211 and the second edge 212 to the bottom of the first groove 21 are the notch depths of the first groove 21; the distance between the third edge 221 and the fourth edge 222 is the notch width of the second groove 22, and the distances from the third edge 221 and the fourth edge 222 to the bottom of the second groove 22 are the notch depths of the second groove 22.

[0057] Refer to Figure 1 and Figure 2 , in the length direction of the sole 10, the notch width of the first groove 21 has a variation trend consistent with the thickness of the sole 10, and the notch width of the second groove 22 has a variation trend consistent with the width of the sole 10. It is easy to understand that the so-called having a consistent variation trend here means that the notch width of the first groove 21 is set according to the thickness variation of the sole 10, and the notch width of the second groove 22 is also set according to the width variation of the sole 10. Among them, the thickness of the sole 10 referred to here means the thickness dimension of the sole 10 including the side wall, rather than the thickness dimension at the midline position in the width direction of the sole 10. Therefore, for a conventional sole 10, its thickness variation trend is generally the thinnest at the forefoot position 16, followed by the heel position 14, and the thickest at the midfoot position 15. Correspondingly, the notch width of the first groove 21 is also the narrowest at the forefoot position 16, followed by the heel position 14, and the widest at the midfoot position 15. Similarly, the width variation trend of the sole 10 is generally the widest at the forefoot position 16, followed by the heel position 14, and the narrowest at the midfoot position 15. Correspondingly, the notch width of the second groove 22 is also the widest at the forefoot position 16, followed by the heel position 14, and the narrowest at the midfoot position 15.

[0058] Refer to Figure 1 , the shape feature of the first groove 21 is that the notch width is small and the notch depth is large. Thus, the sole 10 is separated into an upper part and a lower part by the first groove 21. The setting of the first groove 21 weakens the connection between the upper part and the lower part of the sole 10 and destroys the integrity of the upper part and the lower part of the sole 10, enabling a relatively large degree of horizontal translation to occur between the upper part and the lower part of the sole 10. However, only by setting the first groove 21, the upper part and the lower part of the sole 10 will only have a relatively large degree of horizontal translation when subjected to a horizontal shear force. For this reason, refer to Figure 2, in the sole 10 of this embodiment, a second groove 22 is provided on the bottom surface 13. The shape of the second groove 22 is characterized by a large groove opening width and a small groove depth. With such a setting, when the user wears the shoes and walks or runs, the lower part of the sole 10 will first contact the ground. At this time, the state of the sole 10 can be referred to Figure 3 . The upper part and the lower part of the sole 10 have not yet deformed. At the same time, the friction between the bottom surface 13 of the sole 10 and the ground fixes the lower part of the sole 10 relative to its upper part on the ground. Since the first groove 21 weakens the connection between the upper part and the lower part of the sole 10, the upper part of the sole 10 can translate forward relative to its lower part. After that, refer to Figure 4 . When the sole 10 is subjected to a vertical pressure on the bottom surface 13 provided with the second groove 22, the whole sole 10 is flattened. The bottom of the second groove 22 will be closer to the ground or directly contact the ground. By the deformation of the second groove 22, the edges of the opening of the first groove 21 will approach each other, thereby further increasing the relative sliding between the upper part and the lower part of the sole 10. At the same time, the upper part and the lower part of the sole 10 will also approach each other in the up and down direction. Thus, through the layered shear of the upper part and the lower part of the sole 10, the overall shock absorption performance of the sole 10 is improved. Refer to Figure 5 、 Figure 6 and Figure 7 . During a walking process, the upper part and the lower part of the sole 10 slide relative to each other, and at the same time, the first groove 21 changes from an open state to a closed state and then returns to an open state. During this process, the sole 10 provides sufficient shock absorption for the user's foot, improving the comfort during walking and running. In addition, the shock absorption structure design of the sole 10 also enables the shoes with the sole 10 to be worn on rough roads, such as mountain roads. Through the relative sliding of the upper part and the lower part of the sole 10, the ground contact feeling of the foot can be improved, and the wearing fatigue of the user can be reduced.

[0059] Among them, the notch widths of the first groove 21 and the second groove 22 are made to be consistent with the changing trends of the thickness and width of the sole 10, so that the degree of relative slippage between the upper part and the lower part of the sole 10 can be kept consistent at each position in the length direction of the sole 10, avoiding too small a slippage degree between the upper part and the lower part of the sole 10 due to an insufficient notch width of the first groove 21 at a thicker position of the sole 10, and at the same time, also avoiding too large a slippage degree between the upper part and the lower part of the sole 10 due to too large a notch width of the first groove 21 at a thinner position of the sole 10. The overall deformation of the sole 10 and the shear shock absorption effect between the upper part and the lower part are better. At the same time, the relative slippage between the upper part and the lower part of the sole 10 has a strong correlation with the notch width and the notch depth of the second groove 22. The second groove 22 should have a relatively large notch width and a relatively deep notch depth, so that the sole 10 can be more easily flattened when subjected to a vertical pressure, thereby increasing the relative slippage between the upper part and the lower part of the sole 10. However, the notch depth of the second groove 22 should be kept within an appropriate range to ensure that the sole 10 has good support performance.

[0060] Referring to Figure 1 , the notch depth of the first groove 21 is the largest at the midfoot position 15 of the sole 10. Correspondingly, the notch depth of the first groove 21 is smaller at the forefoot position 16 and the heel position 14 of the sole 10 compared to the midfoot position 15. With such a setting, the upper part and the lower part of the sole 10 have a larger deformation space at the midfoot position 15, and when the sole 10 is bent during stepping, the upper part and the lower part of the sole 10 can still have relative slippage.

[0061] In addition, referring to Figure 1 , a third groove 23 is provided on the rear end side surface of the sole 10 in the length direction and extends along the width direction, and both ends of the third groove 23 are respectively connected to the rear ends of the two first grooves 21 located on the inner side surface 11 and the outer side surface 12 of the sole 10. The third groove 23 connects the two first grooves 21 on both sides, thereby forming a continuous groove structure on the side part of the sole 10, dividing the sole 10 from the heel to the forefoot position 16 into an upper part and a lower part, reducing the pulling force of the heel end face on the upper part and the lower part of the sole 10, and the relative slippage generated between the two is more significant.

[0062] Referring to Figure 1 , the upper and lower groove walls of the first groove 21 extend obliquely towards each other from the notch position and are butted at the midline position corresponding to the notch. The docking line 213 of the upper and lower groove walls of the first groove 21 has a zigzag shape on the projection plane perpendicular to the width direction, and the upper and lower edges of the notch of the first groove 21 are curves that are smoothly transitioned along the length direction and are relatively parallel.

[0063] Specifically, the upper and lower side walls of the first groove 21 are not relatively parallel structures, but relatively inclined structures. The bottom of the first groove 21 is not the flat bottom shape in a conventional groove structure, but a broken line shape formed by the connection of the upper and lower side walls of the first groove 21. The broken line shape here means that the docking line 213 formed by the upper and lower side walls of the first groove 21 at the bottom of the groove is in a broken line shape on the projection plane perpendicular to the width direction of the sole 10. When actually observing the structure of the first groove 21, it can be regarded that the side walls of the first groove 21 form multiple triangular parts. The vertices of these triangular shapes are the broken line vertices 214 in the docking line 213, and the two sides of these triangular shapes extend from the broken line vertices 214 to the edge of the notch of the first groove 21. At the same time, the triangular shapes of the upper and lower side walls are staggered from each other, that is, the triangular shapes on one side wall include relatively protruding parts and relatively recessed parts. The triangular shapes of the protruding parts in the upper side wall and the triangular shapes of the recessed parts in the lower side wall are opposite to each other, and vice versa.

[0064] The docking line 213 is designed to be in a broken line shape, and the edge of the notch of the first groove 21 is designed as a smoothly transitioning parallel curve. When the sole 10 is stepped on and the upper part and the lower part of the sole 10 undergo relative sliding, the broken line-shaped docking line 213 can cause the upper part and the lower part of the sole 10 to produce sliding deformation within a preset range at the position of the first groove 21. The upper side wall and the lower side wall of the first groove 21 will push against each other, preventing the upper part and the lower part from sliding too much. At the same time, the resistance received by the upper part at the first groove 21 during sliding will be feedback to the user's foot, thereby improving the shock absorption performance of the sole 10.

[0065] Among them, at the vertex position of the broken line formed by the docking line 213 of the upper and lower side walls of the first groove 21, the side wall of the first groove 21 with a smaller included angle corresponding to this vertex forms a fourth groove 24 connecting to this vertex and extending to the edge of the notch of the first groove 21, and a fifth groove 25 connecting to the fourth groove 24 and extending in the thickness direction is formed on the inner side surface 11 and / or the outer side surface 12 of the sole 10.

[0066] Specifically, a fourth groove 24 is further provided on the side wall of the first groove 21, and fifth grooves 25 are provided on both the inner side surface 11 and the outer side surface 12 of the sole 10. The fourth groove 24 and the fifth groove 25 cooperate to make the side surface of the sole 10 form an origami-like structure. When the upper part and the lower part of the sole 10 undergo relative sliding, the side walls of the fourth groove 24 and the fifth groove 25 will approach each other, thereby increasing the sliding degree of the upper part and the lower part of the sole 10 and further improving the shock absorption effect.

[0067] Embodiment 2

[0068] With reference to Figure 8 and Figure 9 , on the basis of Embodiment 1 of the present utility model, the depth of the first groove 21 is specifically improved in Embodiment 2. In this embodiment, at the heel position 14 of the sole 10, the depth of the first groove 21 on the inner side 11 is less than the depth of the first groove 21 on the outer side 12.

[0069] Specifically, first with reference to Figure 8 , which is a schematic diagram of the outer side 12 of the shoe, and then with reference to Figure 9 , which is a schematic diagram of the inner side 11 of the shoe. By observing the heel position 14 of the sole 10 in Figure 8 and Figure 9 , it can be found that in the part of the heel position 14, the depth of the first groove 21 on the inner side 11 is relatively shallow, and the depth of the first groove 21 on the outer side 12 is relatively deep. With such a setting, the support performance of the heel position 14 of the sole 10 can be improved through the relatively shallow first groove 21 on the inner side 11, and at the same time, the slip degree between the upper part and the lower part of the sole 10 can be improved through the relatively deep first groove 21 on the outer side 12, thereby improving the shock absorption effect. Therefore, by setting the depths of the first grooves 21 on the outer side 12 and the inner side 11 of the sole 10 differently, a better balance can be achieved between the shock absorption and support performance of the sole 10.

[0070] Embodiment 3

[0071] With reference to Figure 10 , on the basis of Embodiment 1 or Embodiment 2 of the present utility model, the structure of the bottom surface 13 of the sole 10 is improved. In this embodiment, a sixth groove 26 with a depth greater than that of the second groove 22 is provided on the bottom surface 13 at the heel position 14 of the sole 10, and the sixth groove 26 extends from the outer side 12 of the sole 10 to the middle in the width direction of the sole 10 and then extends backward to the rear side surface of the sole 10.

[0072] Specifically, the sixth groove 26 forms an open port on the outer side 12 of the sole 10, and the position of this port is at the middle waist position 15 of the sole 10. After cutting the sole 10 at a slightly forward inclination angle, it extends to the fourth edge 222 of the second groove 22 on the sole 10, and then turns and extends obliquely backward until it reaches the rear end surface of the sole 10, and forms another open port on the rear end surface of the sole 10, and the position of this port is at the position of the rear end surface of the sole 10 close to the inner side 11 of the sole 10. With such a setting, the deformation degree of the sole 10 when being stepped on is higher, thereby improving the closing degree of the first groove 21 and the relative slip degree between the upper part and the lower part of the sole 10, and further improving the shock absorption performance of the sole 10.

[0073] Example 4

[0074] Reference Figure 11 Based on Example 1 or Example 2 of the present utility model, the structure of the bottom surface 13 of the sole 10 is improved in Example 4 of the present utility model. In this embodiment, a sixth groove 26 with a depth greater than that of the second groove 22 is provided on the bottom surface 13 at the heel position 14 of the sole 10. The sixth groove 26 extends from the outer side surface 12 of the sole 10 to the inner side surface 11 and bends backward in the middle in the width direction of the sole 10.

[0075] Specifically, the sixth groove 26 forms an open port on the outer side surface 12 of the sole 10. The position of this port is at the part of the heel position 14 of the sole 10 close to the mid-waist position 15. After cutting the sole 10 at a slightly forward inclination angle, it extends to the fourth edge 222 of the second groove 22 on the sole 10, then turns and extends obliquely toward the rear side of the sole 10, and turns back at the midline position in the width direction of the sole 10 to extend obliquely toward the front side of the sole 10 until it reaches the third edge 221 of the second groove 22, and then turns again and continues to extend at a slightly backward inclination angle until it reaches the inner side surface 11 of the sole 10, and forms another open port on the inner side surface 11 of the sole 10. The position of this port is at the middle part of the heel position 14 of the sole 10. With such a setting, the deformation degree of the sole 10 when being stepped on is higher, thereby improving the closing degree of the first groove 21 and the relative sliding degree between the upper part and the lower part of the sole 10, and further improving the shock absorption performance of the sole 10.
