Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear technology, and in particular to a shoe with a V-shaped layered elastic extension structure. Background Technology
[0002] Shoes are essential clothing for daily walking. With increasing emphasis on exercise, people choose to wear athletic shoes. The soles of athletic shoes differ from ordinary leather or rubber shoes; they are generally soft and elastic, providing cushioning. This enhances elasticity during exercise and some even help prevent ankle injuries. Therefore, athletic shoes are essential for most sports, especially high-intensity physical activities such as basketball, running, and various everyday exercises. To ensure comfort, athletic shoes typically use soft materials for the uppers. However, athletic shoes are often used in high-intensity activities, and in some situations, shoes with soft uppers may lack sufficient foot support, increasing the risk of ankle sprains due to side roll. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a shoe with a V-shaped layered elastic extension structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model adopts the following technical solution:
[0005] A shoe with a V-shaped layered elastic extension structure includes a sole and an upper disposed on the sole. Support plates are respectively disposed on both sides of the shoe. Each support plate includes a support portion fixed to the side of the sole in a V-shape. The opening of the support portion faces upward and the two ends of the opening are located on the upper. The two ends of the support portion are respectively connected to a forefoot arm and a rearfoot arm. Both the forefoot arm and the rearfoot arm are straight structures. The forefoot arm is disposed on the side of the upper at the forefoot position, and the rearfoot arm is disposed on the side of the upper at the rearfoot position.
[0006] Furthermore, the angle between the forefoot arm and the rearfoot arm is greater than the angle of the V-shaped structure of the support part. The forefoot arm extends obliquely to the side of the toe tip, and the rearfoot arm extends obliquely to the heel near the shoe opening and the rear end of the shoe.
[0007] Furthermore, the inner wall of the support is provided with a plurality of protruding posts, and the side of the sole is provided with a slot that is adapted to be inserted and connected to the protruding posts.
[0008] Furthermore, the surface of the protruding post is surrounded by a plurality of protrusions, the surface of the protrusions is arc-shaped, and the sidewall of the slot is provided with a groove that is adapted to fit and be embedded in the protrusions.
[0009] Furthermore, the two forefoot arms of the support plates on both sides of the shoe upper extend forward and connect around the toe end of the shoe upper, while the two rearfoot arms extend backward and connect around the rear heel end of the shoe upper.
[0010] Furthermore, a heel arm is provided at the rear end of the heel position of the shoe upper. The top of the heel arm is connected to the left and right rear heel arms, and its bottom extends downward to the bottom of the shoe upper and is fixedly connected to the sole.
[0011] Furthermore, the thickness of the middle part of the heel arm is thinner than the thickness of the two ends.
[0012] Beneficial effects
[0013] Compared with the prior art, the present invention has at least the following advantages:
[0014] 1. The support plate, formed by the cooperation of the support section, forefoot arm, and heel arm, provides support from the sole to the upper, wrapping around the sides of the foot and reducing excessive deformation of the foot during exercise, such as lateral or supination. The forefoot arm enhances stability when the forefoot exerts force, while the heel arm reduces ankle sway, lowering the risk of sprains. The connection between the forefoot and heel arms and the support section is designed with an arc-shaped structure, which reduces stress concentration and improves the flexibility of the support plate when bending. When the heel is under stress, the heel arm transfers the force to the support section, and the angle change of the support section's V-shaped structure provides cushioning or support.
[0015] 2. The embedded engagement of the protrusion and the slot securely fixes the support piece to the sidewall of the shoe sole, improving the reliability of the support piece connection. The arc-shaped protrusion inserts into the groove to form a snap-fit fixation, enhancing the stability and anti-dislodgement properties of the connection between the protrusion and the slot, and improving the fixation effect of the support piece.
[0016] 3. The support plates on the left and right sides are connected to form an integral support frame, which wraps the shoe as a whole and improves the integrity of the support plate structure. The impact and force during exercise can be distributed to the entire support frame through the surrounding connection part, reducing the load on a single support plate.
[0017] 4. The heel arm design further reduces the risk of ankle inversion or eversion injuries and limits excessive longitudinal displacement of the heel arm. Attached Figure Description

[0028] Example 1
[0029] See Figures 1-4This embodiment provides a shoe with a V-shaped layered elastic extension structure, including a sole 2 and an upper 1 disposed on the sole 2. Support pieces 4 are respectively disposed on both sides of the shoe, and the support pieces are fixed to the shoe by adhesive. Each support piece 4 includes a V-shaped support portion 40 fixed to the side of the sole 2. The opening of the support portion 40 faces upward, and both ends of the opening are located on the upper 1. Forefoot arms 41 and heel arms 42 are respectively connected to both ends of the support portion 40. Both forefoot arms 41 and heel arms 42 are straight structures. The forefoot arm 41 is disposed on the forefoot side of the upper 1, and the heel arm 41 is disposed on the heel side of the upper. The angle between the forefoot arm 41 and the heel arm 42 is greater than the angle of the V-shaped structure of the support portion 40. The forefoot arm 41 extends obliquely to the side of the toe tip, and the heel arm extends obliquely to the heel near the shoe opening and rear end.
[0030] The connection between the forefoot arm 41 and the heel arm 42 and the support portion 40 is designed with an arc-shaped structure, which can reduce stress concentration and improve the flexibility of the support plate 4 when bending. The support plate 4, formed by the cooperation of the support portion 40, the forefoot arm 41, and the heel arm 42, provides support from the sole 2 to the upper 1, wrapping the side of the foot and reducing excessive deformation of the foot during exercise, such as lateral or supination. The forefoot arm 41 can enhance the stability when the forefoot exerts force, while the heel arm 42 enhances the wrapping and locking feel of the heel, reducing ankle swaying and lowering the risk of sprains when landing or jumping. When the heel is under force, the heel arm 42 transmits the force to the support portion 40, and the angle change of the V-shaped structure of the support portion 40 achieves cushioning or support. In this embodiment, the support portion 40 is located in the transition area between the forefoot and the arch, which allows for moderate deformation when the forefoot bends without hindering gait, while also providing support for the arch.
[0031] The inner wall of the support portion 40 is provided with multiple protrusions 5, and the side of the sole 2 is provided with slots 7 that are adapted to and inserted into the protrusions 5. Multiple protrusions 6 are arranged around the surface of the protrusions 5, and the surface of the protrusions 6 has an arc-shaped structure. The side wall of the slot 7 is provided with grooves 8 that are adapted to and embedded into the protrusions 6. In this embodiment, the sole 2 can be made of a material with a certain degree of elasticity and resilience, such as EVA or rubber. The support piece, protrusions, and protrusions are made of TPU material. Through the embedded engagement of the protrusions 5 and the slots 7, the support piece 4 can be firmly fixed to the side wall of the sole, improving the reliability of the support piece connection. When the protrusion 5 is inserted into the slot 7, the arc-shaped protrusions 6 are inserted into the grooves 8, forming a snap-fit fixation, enhancing the stability and anti-dislodgement of the connection between the protrusions 5 and the slots 7, and improving the fixing effect of the support piece 4. When the foot is subjected to force, the forefoot and heel arms of the support plate 4 transmit the force to the middle of the support part 40, and then transmit it to the sole through the rigid connection between the protrusion 5 and the slot 7, which improves the overall torsional resistance of the shoe to a certain extent. The protrusion 5 and the slot 7 can be fixed with glue.
[0032] Example 2
[0033] See Figures 5-6 The difference from Embodiment 1 is that in this embodiment, the two forefoot arms 41 of the two side support plates 4 of the upper extend forward and connect together around the toe end of the upper, while the two rearfoot arms 42 extend backward and connect around the rear end of the heel of the upper 1. This connects the left and right support plates into an integral support frame, providing a holistic wrap around the shoe and improving the overall integrity of the support plate structure. Impact and force during movement can be dispersed throughout the support frame via the connecting area, reducing the load on individual support plates. When the forefoot exerts force, the force can be evenly distributed to the left and right support plates, reducing localized stress concentration. Simultaneously, the forefoot arms 41 wrap around the toe, preventing collapse or deformation of the toe due to prolonged use or external pressure. The rearfoot arms 42 wrap around the heel, forming a wrap around the left and right sides and rear end of the heel, limiting excessive ankle displacement, reducing the risk of sprains, and resisting heel deformation, preventing collapse due to repeated pressure, and maintaining the structural stability of the shoe.
[0034] Preferably, a heel arm 9 is provided at the rear end of the heel position of the upper 1. The heel arm 9 is glued to the upper. The top of the heel arm 9 connects to the left and right rear heel arms 42, and its bottom extends downward to the bottom of the upper 1 and is glued and fixed to the sole 2. The sole 2, the rear heel arm 42, and the heel arm 9 form a triangular support structure, distributing the lateral force on the rear heel arm 42 to the sole 2, preventing the rear heel arm 42 from deforming uncontrollably due to excessive force, and further reducing the risk of ankle inversion or eversion injury. The connection between the heel arm 9 and the sole limits the excessive longitudinal displacement of the rear heel arm 42, reducing the risk of breakage of the rear heel arm 42. At the same time, the heel arm 9 improves the comfort of the shoe during exercise through its own elastic deformation during heel movement.
[0035] The heel arm 9 is made of TPU material, and the side of the heel arm 9 that is bonded to the upper 1 is set as a rough surface. Preferably, the thickness of the middle part of the heel arm 9 is thinner than that of the two ends, which ensures the flexibility of the heel arm 9 during movement and strengthens the connection structure between the two ends of the heel arm 9 and the upper 1 and the sole 2.
[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
