Description

Technical Field

[0001] This utility model relates to the field of footwear, and more particularly to a support member, as well as a sole and a shoe containing the support member. Background Technology

[0002] In sports like basketball, "lateral shearing reaction speed" refers to an athlete's ability to react quickly and initiate lateral movement when faced with changes in the lateral direction of the court. In basketball, offensive players with the ball need to use lateral shearing reaction speed to quickly change direction and shake off defenders. Defenders, in turn, need to use lateral shearing reaction speed to adjust their defensive positions in time. When an offensive player makes a lateral change of direction, the defender must react quickly, changing their own direction of movement to stay in front of the offensive player and disrupt their offensive path. A slow lateral shearing reaction speed will reduce the success rate of both drives and defenses.

[0003] Existing basketball shoes incorporate carbon fiber plates or thermoplastic polyurethane support plates in key areas of the midsole, such as below the arch and in the forefoot, to improve the overall torsional rigidity and stability of the shoe. These support structures reduce deformation of the foot under lateral shear forces, thereby improving responsiveness.

[0004] However, the carbon fiber plates or thermoplastic polyurethane support plates currently used in shoes have insufficient strength and stiffness, and weak impact resistance. The carbon plates are prone to breakage when subjected to excessive lateral impact or compression. In order to increase the strength and stability of the carbon plates, their thickness and weight need to be increased, but this will affect the lightness and flexibility of the shoes.

[0030] In order to better understand the purpose, structure and function of the utility model, the support of the utility model is described in detail below in combination with the drawings.

[0031] As Figures 1 to 5As shown, the support member comprises a first support unit and a second support unit arranged oppositely, the first support unit comprises a forefoot region, the inner side of the sole body is defined as the medial side of the sole body, and the outer side of the sole body is defined as the lateral side of the sole body, the lateral side of the forefoot region of the first support unit is provided with a first support area, the second support unit is arranged relative to the first support area, the first support area and the second support unit are mutually embedded to form a fixed connection through at least one concave-convex structure, so that the support member becomes an integral structure, the concave-convex structure limits the relative displacement or rotation between the first support unit and the second support unit, thereby enabling the support member to withstand greater impact load and complex stress, and improving the overall stability and strength of the support member.

[0032] The end of the sole body close to the human toe is defined as the front side of the sole body, the end of the sole body close to the human heel is defined as the rear side of the sole body, the line connecting the front side and the rear side is defined as the longitudinal direction, the line connecting the medial side and the lateral side is defined as the transverse direction, and the line connecting the top and the bottom of the sole body is defined as the vertical direction, each concave-convex structure is arranged in transverse extension, the concave-convex structure is composed of a convex part and a concave part, when the two are transversely extended and connected to each other, an interlocking effect is formed, which enables the connection part to more effectively transfer and disperse stress when subjected to transverse shear force. The convex part is embedded in the concave part, increasing the contact area and friction of the connection surface, thereby improving the stability and shear resistance of the connection. In addition, the embedding and fixing of the concave-convex structure is realized through precise fitting and installation, which not only increases the tightness of the connection, but also improves the strength of the connection part, so that the concave-convex structure can better resist deformation and damage when subjected to transverse shear force, and maintain the integrity and stability of the connection.

[0033] The convex part of the concave-convex structure has a support surface extending along the side wall of the forefoot region of the first support unit, when the human foot moves transversely in the movement, the transverse shear force is applied to the lateral side of the forefoot of the first support unit during starting, the transverse shear force is transmitted to the second support unit through the support surface, and then quickly transmitted to the ground. It can be understood that the inclined support surface in the concave-convex structure is similar to a starting device in track and field, which can effectively transmit this transverse shear force to the ground, and the ground also generates an equal and opposite reaction force acting on the human foot.

[0034] It should be noted that the starting device can provide strong support for the athlete in the sprint, and when the athlete steps off the starting device, the structure of the starting device can resist the strong thrust of the athlete's leg and give a stable reaction force. Similarly, the design structure similar to the starting device in the concave-convex structure can also provide stable support at the starting moment. When starting in the transverse shear, the stability of the foot is crucial. If the foot is not well supported, it is easy to sway or the force is not evenly transmitted. The support surface structure similar to the starting device can provide a solid transverse support platform for the foot, and then the concave-convex structure can ensure that the sole is tightly attached to the sole, preventing the sole from sliding in the shoe. This enables the human body to more accurately control the force direction of the foot, concentrate the force in the transverse direction, thereby improving the transverse shear reaction speed.

[0035] It can be understood that the concave-convex structure is arranged along the transverse direction to optimize the force transmission path. At the starting moment of the transverse start, the force is transmitted from the leg muscles to the foot through the bones, and then the shoe contacts the ground. The inclined support surface in the concave-convex structure can make the force more directly transmitted from the foot to the ground. The support member reduces the loss of force in the transmission process through the concave-convex structure. Similar to the rigid body model in physics, ideal force transmission has no energy loss. The concave-convex structure enables the human body to more efficiently convert the muscle contraction force into transverse displacement when starting the transverse shear action, thereby accelerating the transverse reaction speed.

[0036] In order to better understand the purpose, structure and function of the utility model, the support member will be further described in detail below with reference to the specific structure of the support member.

[0037] As shown in Figures 1 to 5 The support member includes a first support unit 100 and a second support unit 200 arranged opposite to each other. The first support unit 100 includes a forefoot region, a midfoot region and a heel region connected in sequence. The outer side of the forefoot region is provided with a first support area 101. The second support unit 200 is arranged opposite to the outer side of the forefoot region of the first support unit 100. The second support unit 200 includes a second support area 201. The second support area 201 is arranged opposite to the first support area 101 and is connected by a first assembly. The first assembly includes a convex rib and a groove that can be engaged with each other. The convex rib and the groove are arranged along the transverse direction. When the first support area 101 is subjected to a transverse pressure from the inner side to the outer side, the pressure can be transmitted to the second support area 201 along the transverse direction through the first assembly. The second support area 201 obtains support force through the ground and then feeds it back to the first support area 101 along the transverse direction through the first assembly. Therefore, when the human body moves transversely, the human body can more accurately control the force direction of the foot, concentrate the force in the transverse direction, and thereby improve the transverse shear reaction speed.

[0038] It should be noted that the first support area 101 and the second support area 201 can also be arranged close to the inner side of the forefoot region, or arranged at the middle position between the outer side and the inner side of the forefoot region, and the first assembly is correspondingly arranged between the first support area 101 and the second support area 201, which can also achieve the effect of concentrating the force in the lateral direction when the human body moves laterally, thereby improving the lateral shear reaction speed. In the embodiment, the first support area 101 is arranged close to the outer side of the forefoot region, and the preferred scheme is that one end of the first assembly extends to the inner side of the forefoot region and the other end of the first assembly extends upward to the outer side of the forefoot region in combination with the first assembly.

[0039] The above-mentioned convex ribs and grooves are arranged in the lateral direction, which includes not only the horizontal lateral arrangement perpendicular to the front-rear connecting line, but also the lateral arrangement non-perpendicular to the front-rear connecting line, as long as the effect of transmitting the force on the outer side of the forefoot of the support member in the direction of the inner side and the outer side can be achieved.

[0040] It can be understood that the first assembly can also be arranged in a riveting or screwing structure, and the second support area 201 and the first support area 101 are correspondingly fixedly connected by rivets or screws, wherein the rivets and screws are arranged in the lateral direction, and can also guide the interaction force between the first support unit 100 and the second support unit 200 to be transmitted in the lateral direction, thereby improving the lateral shear reaction speed.

[0041] Specifically, the first assembly includes a first convex rib 102 and a first groove 103 arranged on the first support area 101, and a second convex rib 202 and a second groove 203 arranged on the second support area 201, a plurality of first convex ribs 102 and first grooves 103 are arranged alternately, a plurality of second convex ribs 202 and second grooves 203 are arranged alternately, the first convex rib 102 is protrudingly arranged on the lower surface of the first support area 101, the second convex rib 202 is protrudingly arranged on the upper surface of the second support area 201, then the first convex rib 102 is clamped with the second groove 203, the first groove 103 is clamped with the second convex rib 202, and the first support unit 100 and the second support unit 200 are fixedly connected to form the overall structure of the support member by means of adhesive, so as to ensure that the first support unit 100 and the second support unit 200 do not slide relative to each other.

[0042] The first rib 102 and the first groove 103 in the first component are arranged alternately in the longitudinal direction, and the second rib 202 and the second groove 203 are arranged alternately in the longitudinal direction. On the one hand, the first support area 101 and the second support area 201 are arranged in a long strip shape, that is, the length from the front side to the back side is greater than the length from the inner side to the outer side, so as to cover more of the lateral side of the forefoot of the human body in the longitudinal direction, thereby facilitating the improvement of the lateral shear force of the forefoot area. On the other hand, during the extension stage, the forefoot area of the human body completes the action of pushing the ground through lateral bending, so that the structure provides lateral starting support while taking into account the need for flexibility of the forefoot area.

[0043] Further, the first rib 102 includes a first end 104 and a second end 105 arranged oppositely in the transverse direction, and a rib portion between the first end 104 and the second end 105. The second rib 202 also includes a first end 204 and a second end 205 arranged oppositely in the transverse direction, and a rib portion between the first end 204 and the second end 205. The first end 104, 204 extends towards the inner side of the sole body, and the second end 105, 205 extends towards the side wall of the outer side of the sole body, so that the cross section of the rib in the transverse direction is in an arc-shaped curved structure. The purpose of arranging the curved structure rib portion is to disperse the lateral force to the upper side of the support and the bottom of the support along the rib portion when the middle position of the rib portion is subjected to the lateral force, thereby obtaining the support of the lateral side and the bottom of the support. In particular, the force transmitted along the bottom of the second support unit 200 in the transverse direction can increase the lateral shear force of the support.

[0044] As shown in Figure 1 and Figure 3 Preferably, the upward face of the rib portion of the second rib 202 is defined as the second abutting face 206, and the downward face of the rib portion of the first rib 102 is defined as the first abutting face 106. The distance between the first abutting face 106 and the first support area 101, and the distance between the second abutting face 206 and the second support area 201 are both the first thickness 207. The first thickness 207 gradually decreases in the direction from the middle position of the abutting face to the first end 104, 204, and the first thickness 207 gradually decreases in the direction from the middle position of the abutting face to the second end 204, that is, the cross section of the rib in the transverse direction gradually narrows from the middle to the two ends, so that the rib as a whole has a wedge structure with a thick middle and flat ends, which is similar to the structure of the starting block. When the force is applied to the position of the maximum first thickness 207 in the middle of the rib portion, the force is first received by the second abutting face 206. Due to the wedge structure of the rib, the force is gradually dispersed along the slope of the abutting face and transmitted in the transverse direction to the first end 104, 204 and the second end 105, 205 with the minimum first thickness 207, thereby accelerating the shear speed in the transverse direction.

[0045] It can be understood that the first thickness 207 can also gradually decrease from the middle position to one side of the first end or the second end, that is, form a one-sided gradually narrowing structure, which can also achieve the effect of accelerating the transverse shear speed.

[0046] It should be noted that the engagement structure of the convex ribs and the grooves can achieve the effect of accelerating the transverse shear speed by arranging a group of convex ribs and grooves on the outside of the forefoot. If multiple groups are arranged, the self-locking property between the engagement structures can be fully utilized to enhance the stability of the first assembly in maintaining the support after being stressed.

[0047] Preferably, the rib portion of the first convex rib 102 further comprises a first connecting surface, and the rib portion of the second convex rib 202 further comprises a second connecting surface. The first connecting surface is arranged relative to the first abutting surface 106 and is fixedly connected with the first support area 101. The second connecting surface is arranged relative to the second abutting surface 206 and is fixedly connected with the second support area 201. The width of the first connecting surface in the longitudinal direction of the sole body is defined as the first width 208, and the distance between the front side and the rear side of the first abutting surface 106 and the distance between the front side and the rear side of the second abutting surface 206 are defined as the second width 209. The first width 208 is 2.5mm to 4.5mm, the second width 209 is 7.5mm to 9.5mm, and the first thickness 207 is 1.5mm to 4.5mm, so that the middle part of the first convex rib 102 and the second convex rib 202 has a trapezoidal structure, and the inclined surface between the connecting surface and the abutting surface helps the forefoot area of the support to bend and improves the flexibility of the support.

[0048] Preferably, the first width 208 is 3.5mm, the second width 209 is 8.5mm, and the first thickness 207 is 2mm, or the first width 208 is 3.5mm, the second width 209 is 8.5mm, and the first thickness 207 is 4mm. With this parameter setting, the support has the fastest transverse shear speed, while the flexibility of the forefoot area of the support is also considered.

[0049] It can be understood that the first groove 103 has the same size structure as the second convex rib 202, and the second groove 203 has the same size structure as the first convex rib 102, so that the first convex rib 102 is connected with the second groove 203, and the first groove 103 is connected with the second convex rib 202. The above two can form a tight connection, so the specific structure and parameters of the first groove 103 and the second groove 203 can be realized by referring to the first convex rib 102 and the second convex rib 202 by those skilled in the art, and will not be described here.

[0050] As Figure 1 and Figure 2Further, the support member further comprises a second component in the form of a strip, the first support region 101 and the second support region 201 are connected by the second component, the second component comprises a first protrusion 107 and a first accommodating groove 210, the first protrusion 107 is arranged above the outer side of the forefoot region, close to one side of the second end of the protruding rib and protrudes outwardly of the support member, the first accommodating groove 210 is located on the second support region 201 and protrudes outwardly of the second support region 201, and a groove matching the structure of the first protrusion 107 is formed on the inner side of the second support region 201, so that the first protrusion 107 can be embedded in the first accommodating groove 210, so that the first support region 101 and the second support region 201 are arranged in close contact with each other. Preferably, the first protrusion 107 and the first accommodating groove 210 are bonded by an adhesive, so that relative sliding between the two does not occur.

[0051] The second component extends in the direction from the front side to the rear side, so that the transverse force acting on the outer side of the first support region 101 is transmitted in the extension direction of the second component to the front side and the rear side, thereby forming rapid and effective lateral support on the outer side of the second support region 201, which helps to maintain the overall stability of the support member.

[0052] Further, the first protrusion 107 comprises a third end located on the front side of the sole body and a fourth end located on the rear side of the sole body, the thickness of the first protrusion 107 protruding outwardly is defined as a second thickness, and the distance between the vertical top and the bottom of the first protrusion 107 is defined as a third width, the second thickness gradually decreases from the middle of the first protrusion 107 to the third end and the fourth end, and the third width gradually decreases from the middle of the first protrusion 107 to the third end and the fourth end, so that the first protrusion 107 has a triangular wedge structure as a whole. When the forefoot of the human foot applies a transverse force on the outer side of the first support region 101, due to the wedge structure of the first protrusion 107, the force will gradually disperse along the inclined surface of the first protrusion 107 and the first accommodating groove 210, and be conducted longitudinally to the third end and the fourth end with the smallest second thickness, thereby accelerating the decomposition of the transverse force and further forming rapid and effective lateral support on the outer side of the second support region 201, thereby improving the stability of the support member.

[0053] The utility model also provides a sole comprising the first support region 100 and the second support region 201, the heel support member 300, the bottom support member 400 and the outsole 500.

[0057] 2. The first protruding ribs and the first recesses in the first assembly are arranged alternately in the longitudinal direction, the second protruding ribs and the second recesses are arranged alternately in the longitudinal direction, in the toe-off stage, the forefoot region of the human foot completes the toe-off action through transverse bending, this structure provides transverse starting support while taking into account the bending flexibility requirement of the forefoot region;
