Description

Technical Field

[0001] This invention relates to a dynamically adaptable shoe sole support frame, belonging to the field of sports shoes. Background Technology

[0002] The addition of reinforced support structures to some athletic shoes provides extra support and torsional rigidity to the sole. Conventional support structures are composite materials formed by bonding epoxy resin and carbon fiber filaments, characterized by high strength, high stiffness, and lightweight. While this material plays a role in providing torsional stability in athletic shoes, its high rigidity makes it unsuitable for non-active activities, especially during daily commutes or long walks. The high rigidity of the support structure also provides strong support to the sole, increasing pressure on the plantar fascia. This leads to prolonged tension on the plantar fascia, potentially causing tendon fatigue and inflammation, and even affecting the normal flexion of the metatarsophalangeal joint. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shoe sole support frame that dynamically adapts to the sole of the foot, so as to solve the problem that the existing support structure is not suitable for activities in non-movement states, especially during daily commutes or long-term walking. The high rigidity of the support structure also provides strong support to the sole of the foot, which can increase the pressure on the plantar fascia, causing the plantar fascia to be in a state of continuous tension for a long time, which can easily cause tendon fatigue and inflammation, and even affect the normal bending of the metatarsophalangeal joint.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a shoe sole support frame that dynamically adapts to the sole of the foot, the structure of which includes a central frame layer;

[0005] The central skeleton layer consists of a forefoot, an arch, and a heel from front to back. The forefoot is longitudinally cut to form several cutting slits and a push plate. The arch has several positioning protrusions extending at intervals on both sides.

[0006] Furthermore, the push plate extends upwards along the length direction away from the central body, and the middle of the push plate is concave to form an arc shape, which is connected to the arch and heel in sequence to form a shovel shape. The movement trajectory of the center of gravity transitions from the heel to the forefoot, providing the necessary propulsion and support for the movement.

[0007] Furthermore, the end of the cut away from the arch of the foot is an open cut, and its shape is an arc similar to the outer contour trajectory. The open cut is designed to better fit the trajectory of the forefoot movement.

[0008] Furthermore, the arch portion is provided with several limiting openings on both sides. The arch portion has a wave-shaped design, and the opening of the limiting opening is connected to the corresponding positioning protrusion. The limiting openings are provided to prevent displacement in the sole of the shoe.

[0009] Furthermore, the positioning protruding edge extends outward and vertically downward, forming a corresponding groove at the bottom of the arch of the foot. The groove forms a buffer cavity that absorbs the impact force of the foot first when the heel strikes the ground.

[0010] Furthermore, one end of the heel bends downward and extends to provide a support plate, which, together with the groove, forms an arc-shaped cushioning mechanism on the heel. When the heel touches the ground, the body's center of gravity is concentrated on the heel, and multiple positioning protrusions form multiple cushioning points, naturally dispersing the pressure from multiple force points.

[0011] Furthermore, the lower surface of the push plate is provided with a plurality of anti-slip limiting grooves, which are spaced laterally along the push plate. The anti-slip limiting grooves are strip-shaped or curved, which effectively prevents slippage during movement, limits displacement under complex movement trajectories, and improves the flexibility of movement.

[0012] Furthermore, the cross-section of the push plate and the cut is wavy. During movement, the cross-section of the push plate and the cut forms a wavy dynamic plane, reducing rigid constraints on the forefoot and increasing comfort during lateral foot movements.

[0013] Furthermore, the forefoot, arch, and heel are connected as a single unit, which improves production efficiency and flexibility.

[0014] Furthermore, the central skeleton layer is made of specially formulated TPU, which has high tensile strength and impact resistance. It can maintain the integrity of the structure when subjected to external forces, is not prone to breakage or deformation, and quickly recovers its original shape after compression or stretching, providing good cushioning and rebound effects and reducing the impact on the feet during exercise.

[0015] The beneficial effects of this invention are as follows: The central skeleton layer of this invention, as a support structure in the sole, uses several cutouts and push plates in the forefoot area. In both active and inactive states, foot deformation is concentrated in the forefoot. With different left, right, forward, and backward movements, the forefoot adopts different bending postures, creating a dynamic plane in different directions of movement and allowing the foot to return to a natural posture during movement. The positioning protrusions in the arch and the support plate in the heel create an arc-shaped cushioning mechanism in the heel. When the heel strikes the ground, multiple positioning protrusions form multiple cushioning points, naturally dispersing pressure and providing strong support to cushion and stabilize the foot.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] [A dynamically adaptable shoe sole support frame according to the present invention]

[0026] Example 1

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution for a shoe sole support frame that dynamically adapts to the foot: its structure includes a central frame layer 1;

[0028] The central skeletal layer 1 consists of a forefoot portion 11, an arch portion 12, and a heel portion 13, arranged sequentially from front to back. The forefoot portion 11 is longitudinally cut to form several slits 111 and a push plate 112. The arch portion 12 has several positioning protrusions 122 extending at intervals on both sides. Through the slits 111 and push plates 112 in the forefoot portion 11, the forefoot and foot exhibit different bending postures as the center of gravity changes from left to right and front to back, allowing the forefoot to form a dynamic plane in different directions of movement, thus returning the movement state to a natural posture.

[0029] Please see Figure 3 In order to provide a support structure that facilitates movement, the push plate 112 extends and curves upward along the length direction away from the central body 121. The middle of the push plate 112 is concave to form an arc shape, and is connected to the arch part 12 and the heel part 13 in sequence to form a shovel shape. The design of the shovel-shaped structure cleverly combines stability and flexibility, optimizes the dynamic response during movement, and better fits the movement trajectory of the center of gravity transitioning from the heel to the forefoot during movement, providing the necessary propulsion and support for movement.

[0030] Please see Figure 3 In order to make the dynamic plane fit the foot movement better, the end of the cut 111 away from the arch 12 is an open cut, and its shape is an arc similar to the outer contour trajectory.

[0031] Please see Figure 2 , Figure 3 To prevent displacement within the sole, the arch portion 12 is provided with several limiting openings 123 on both sides. The arch portion 12 has a wave-shaped design, and the openings of the limiting openings 123 are connected to the corresponding positioning protrusions 122.

[0032] Please see Figure 3 , Figure 4 To provide stronger support and stability, the positioning protrusion 122 extends outward and vertically downward, forming a corresponding groove 124 at the bottom of the arch portion 12. One end of the heel portion 13 bends downward and extends to provide a support piece 131. When the sole contacts the ground, the heel section of the sole absorbs the impact force of the foot first. Through the positioning protrusion 122 provided in the arch portion 12 and the support piece 131 provided in the heel portion 13, an arc-shaped cushioning mechanism is formed in the heel. When the heel lands, the center of gravity of the whole body is concentrated on the heel, and multiple positioning protrusions 122 form multiple cushioning points to naturally disperse the pressure from multiple force points.

[0033] Please see Figure 2To prevent displacement within the sole, the lower surface of the push plate 112 is provided with several anti-slip limiting grooves 113. The anti-slip limiting grooves 112 are spaced laterally along the push plate 113. The anti-slip limiting grooves 113 are strip-shaped. The strip-shaped anti-slip limiting grooves 113 effectively prevent the push plate from sliding during movement by increasing the friction between the push plate 112 and the contact surface.

[0034] To optimize the structure of the dynamic plane, the cross-section of the push plate 112 and the cut 111 is wavy.

[0035] Please see Figure 2 For ease of production, the forefoot 11, arch 12, and heel 13 are connected as a single unit.

[0036] To prevent excessive rigidity, the material of the central skeleton layer 1 is specially formulated TPU.

[0037] Example 2

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution for a shoe sole support frame that dynamically adapts to the foot: its structure includes a central frame layer 1;

[0039] The central skeletal layer 1 consists of a forefoot portion 11, an arch portion 12, and a heel portion 13, arranged sequentially from front to back. The forefoot portion 11 is longitudinally cut to form several slits 111 and a push plate 112. The arch portion 12 has several positioning protrusions 122 extending at intervals on both sides. Through the slits 111 and push plates 112 in the forefoot portion 11, the forefoot and foot exhibit different bending postures as the center of gravity changes from left to right and front to back, allowing the forefoot to form a dynamic plane in different directions of movement, thus returning the movement state to a natural posture.

[0040] Please see Figure 3 In order to provide a support structure that facilitates movement, the push plate 112 extends and curves upward along the length direction away from the central body 121. The middle of the push plate 112 is concave to form an arc shape, and is connected to the arch part 12 and the heel part 13 in sequence to form a shovel shape. The design of the shovel-shaped structure cleverly combines stability and flexibility, optimizes the dynamic response during movement, and better fits the movement trajectory of the center of gravity transitioning from the heel to the forefoot during movement, providing the necessary propulsion and support for movement.

[0041] Please see Figure 3 In order to make the dynamic plane fit the foot movement better, the end of the cut 111 away from the arch 12 is an open cut, and its shape is an arc similar to the outer contour trajectory.

[0042] Please see Figure 2 , Figure 3 To prevent displacement within the sole, the arch portion 12 is provided with several limiting openings 123 on both sides. The arch portion 12 has a wave-shaped design, and the openings of the limiting openings 123 are connected to the corresponding positioning protrusions 122.

[0043] Please see Figure 3 , Figure 4 To provide stronger support and stability, the positioning protrusion 122 extends outward and vertically downward, forming a corresponding groove 124 at the bottom of the arch portion 12. One end of the heel portion 13 bends downward and extends to provide a support piece 131. When the sole contacts the ground, the heel section of the sole absorbs the impact force of the foot first. Through the positioning protrusion 122 provided in the arch portion 12 and the support piece 131 provided in the heel portion 13, an arc-shaped cushioning mechanism is formed in the heel. When the heel lands, the center of gravity of the whole body is concentrated on the heel, and multiple positioning protrusions 122 form multiple cushioning points to naturally disperse the pressure from multiple force points.

[0044] Please see Figure 2 To prevent displacement within the sole, the lower surface of the push plate 112 is provided with a plurality of anti-slip limiting grooves 113. The anti-slip limiting grooves 112 are arranged laterally along the push plate 113 at intervals. The anti-slip limiting grooves 113 are curved. The curved anti-slip limiting grooves 113 can better adapt to the anti-slip requirements of the push plate under complex movement trajectories and improve movement flexibility.

[0045] To optimize the structure of the dynamic plane, the cross-section of the push plate 112 and the cut 111 is wavy.

[0046] Please see Figure 2 For ease of production, the forefoot 11, arch 12, and heel 13 are connected as a single unit.

[0047] To prevent excessive rigidity, the material of the central skeleton layer 1 is specially formulated TPU.

[0048] When in use, during daily commutes or long walks, the heel of the foot contacts the ground first when the shoe touches the ground. The heel section composed of the heel part 13 and the arch part 12 of the central skeleton layer 1 absorbs the impact force of the sole first. Through the positioning protrusions set in the arch part 12 and the support plate 131 set in the heel part 13, the heel forms an arc-shaped cushioning mechanism. When the heel hits the ground, multiple positioning protrusions 122 form multiple cushioning points to naturally disperse the pressure from multiple force points. Then the forefoot contacts the ground, and the body's center of gravity naturally shifts to the forefoot. At this time, the deformation of the foot is concentrated in the forefoot. Through the several cutting holes 111 and the push plate 112 set in the forefoot part 11, the forefoot presents different bending postures as the center of gravity changes in the left, right, front and back, so that the forefoot forms a dynamic plane in different directions of movement, allowing the movement state to return to a natural posture. This ensures that the forefoot will not be "too stiff" in the normal non-stress state when not in motion.
