Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a flexible, easy-to-wear and easy-to-take-off shoe. Background Technology

[0002] As children grow and develop, their foot shape, foot structure, and shoe-wearing habits differ significantly from adults. Children's feet are diverse, with varying instep heights, arch shapes, and calcaneal development, and these are constantly changing. Therefore, shoes designed for children need to pay special attention to ease of wear and comfort to minimize the need for children to adapt to the shoes. Currently, solutions for slip-on shoes are relatively mature on the market, such as Velcro, adjustable elastic straps, laces, screw-on buckles, and slip-ons. However, when these solutions are applied to children's shoes, several problems arise. For example, while Velcro is convenient, its length may be insufficient for children with wide feet, causing the burrs to be exposed, and it easily attracts dust after prolonged use, reducing its stickiness. Slip-ons may be too tight or too loose for children with wide feet or high insteps. Adjustable elastic straps may lose their elasticity after prolonged use. While screw-on buckle systems are suitable for older children, they may be difficult for infants and toddlers to operate independently. To address these issues, existing easy-on / off solutions on the market incorporate various movable components. These components attach to the sole or other parts of the shoe and allow a portion of the shoe to move under pressure, enabling the user's foot to quickly slip into the shoe. However, these existing easy-on / off solutions are primarily designed for adult shoes, and children of different ages differ significantly from adults in how they put on and take off shoes. Therefore, easy-on / off solutions for children's shoes need to be more tailored to children's actual needs. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide an elastic, easy-to-wear shoe that is easy to open and close while having excellent recovery performance, ensuring convenience and comfort during the putting on and taking off process.

[0004] To achieve the above objectives, the various embodiments of the present invention employ the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to an elastically folding, easy-to-wear shoe, comprising a shoe body; the shoe body includes a sole, an upper, and an elastic element; the upper includes a forefoot portion, a heel portion, and a connecting portion all connected to the sole, the connecting portion being close to the sole and connecting the forefoot portion and the lower part of the heel portion near the sole, the forefoot portion and the upper part of the heel portion being separated from each other away from the sole; the heel portion is adapted to switch between a first state and a second state under the action of external force, when the heel portion is in the first state, it is close to the forefoot portion and cooperates with the forefoot portion to form a complete shoe opening, when the heel portion is in the second state, it is away from the forefoot portion and the shoe opening is opened; the elastic element connects the forefoot portion, the heel portion, and the connecting portion, the elastic element is adapted to unfold under the action of external force to allow the heel portion to enter the second state, once the external force is lost, the elastic element rebounds and resets to allow the heel portion to return to the first state.

[0006] The second technical solution is based on the first technical solution, wherein the elastic member includes a first elastic part, a second elastic part, and an elastic bottom. The first elastic part is connected to the heel part, the second elastic part is connected to the forefoot part, and the elastic bottom is connected to the connecting part. The first elastic part is adapted to unfold under the action of an external force away from the forefoot part, and the first elastic part moves away from the second elastic part with the elastic bottom as a fulcrum, so that the heel part is in a second state. The first elastic part rebounds and recovers when the external force away from the forefoot part is removed, and the first elastic part moves closer to the second elastic part, so that the heel part returns to the first state.

[0007] The third technical solution is based on the second technical solution, wherein the elastic element is a U-shaped structure, the first elastic part and the second elastic part are the two sides of the U-shaped structure, and the elastic bottom is the bottom of the U-shaped structure; when the elastic element is not subjected to external force, the opening of the U-shaped structure is closed, and the first elastic part is close to the second elastic part; when the elastic element is subjected to external force, the opening of the U-shaped structure is opened, and the first elastic part is away from the second elastic part.

[0008] The fourth technical solution is based on the third technical solution, wherein the elastic element is disposed in an inclined manner in the forefoot, heel and connecting part, and the opening direction of its U-shaped structure forms an angle with the extension direction of the sole and extends obliquely upward.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the length of the first elastic part is greater than the length of the second elastic part.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the number of elastic elements is two, and the two elastic elements are respectively disposed on both sides of the shoe upper.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the elastic element is made of a highly elastic material.

[0012] The eighth technical solution is based on the first technical solution, wherein the elastic element is fixedly installed on the shoe upper by means of sewing, gluing or snapping to connect with the forefoot part, heel part and connecting part.

[0013] As can be seen from the above description of the various embodiments of the present invention, compared with the prior art, the various embodiments of the present invention have the following advantages:

[0014] Beneficial effects:

[0015] In the first technical solution and related embodiments, this elastic opening and closing easy-to-wear shoe design achieves easy-to-wear and easy-to-remove functionality through an elastic element, while ensuring the comfort and stability of the shoe. The elastic element connects the forefoot and heel of the shoe, realizing a separate design for the two parts. This design gives the forefoot and heel elastic characteristics. When the wearer is ready to put on the shoe, the elastic element can easily unfold, widening the shoe opening to facilitate the wearer's foot entering the shoe. Once the wearer's foot is inside the shoe, the elastic element quickly returns to its original position. Its elasticity and resilience help the shoe closely conform to the wearer's foot curve, providing necessary support and reducing foot sway during walking or running and jumping, thereby ensuring the stability of the shoe in various movements. When the wearer is ready to take off the shoe, the elastic element unfolds again, making it easy for the foot to exit the shoe. Subsequently, the elastic element automatically returns to the tightened state, narrowing the shoe opening and returning to its original position. The entire elastic opening and closing process simplifies the process of putting on and taking off the shoe. This design allows the shoe to adapt to changes in the wearer's foot shape during the process of putting on and taking off the shoe, avoiding the compression or discomfort that may occur with traditional shoes. This simple yet efficient design avoids the use of complex moving components, making the shoes both practical and stylish. The use of elastic elements also helps cushion the impact on the feet during walking or exercise, reducing fatigue and discomfort. Although the upper parts of the forefoot and heel are separate, the connecting part near the sole connects the lower parts of the forefoot and heel, and their connection with the elastic elements ensures the stability and support of the shoe when worn. At the same time, this separate design also gives the shoe a unique line and sense of layering, which, combined with the decorative design of the elastic elements, creates a shoe that is both comfortable and fashionable.

[0016] In the second technical solution and related embodiments, the elastic element includes a first elastic part, a second elastic part, and an elastic sole. This structure allows the heel of the shoe to open easily when subjected to external force, forming a larger shoe opening and greatly improving the ease of putting on and taking off the shoe. The rebound and recovery performance of the elastic element allows the shoe to automatically return to its original state after the external force is removed, that is, the heel and forefoot cooperate to form a complete shoe opening. This feature not only ensures the structural stability of the shoe but also ensures the comfort and safety of the shoe when worn. By using the elastic sole as a fulcrum, the first elastic part can move away from the second elastic part when subjected to external force, thereby opening the heel and making the opening and closing action of the shoe smoother.

[0017] In the third technical solution and related embodiments, the U-shaped structure design gives the elastic element excellent structural stability. This structure can effectively disperse external forces, such as the force generated when the wearer puts on or takes off shoes or walks, thereby ensuring that the elastic element can maintain its shape and function for a long time. The U-shaped structure generally has good elastic properties. This allows the elastic element to easily unfold when subjected to external force, making it convenient for the wearer to put on or take off shoes; and after the external force disappears, the elastic element can quickly return to its original state, maintaining the stability of the shoe. Due to the characteristics of the U-shaped structure, the elastic element can adapt to different foot shapes and foot structures. Whether the wearer has wide feet or a high instep, this structure can adapt to a certain extent and provide a comfortable wearing experience. At the same time, the U-shaped structure is relatively simple and easy to manufacture and process.

[0018] In the fourth technical solution and related embodiments, due to the upward-sloping design of the elastic element opening, when the wearer tries to put on the shoe, the foot can more easily enter the shoe along this slope. Similarly, when taking off the shoe, the foot can easily move out along this direction. The sloped design helps reduce friction between the foot and the shoe upper, especially during the process of putting on and taking off shoes, which further increases the ease of putting on and taking off shoes. Due to the sloped design, the pressure points of the elastic element on the shoe upper are more evenly distributed, which helps reduce discomfort or pressure that the wearer may feel when putting on and taking off shoes. This sloped design takes into account ergonomics and foot anatomy, allowing the shoe to conform to the curve of the foot when worn, providing excellent comfort and support. At the same time, this sloped design not only considers practicality but also aesthetics. The streamlined U-shaped sloped design makes the shoe look more stylish and beautiful, meeting the aesthetic needs of modern people.

[0019] In the fifth technical solution and related embodiments, because the first elastic part is connected to the heel and is relatively long, it can provide stronger support when the wearer puts on the shoe, ensuring the stability of the shoe, especially in the heel area. Although the first elastic part is long, its design near the heel makes it easier for the foot to enter the shoe when the wearer tries to put it on. Simultaneously, when it is necessary to take off the shoe, the longer length of the first elastic part provides more room for elastic deformation, making the process of taking off the shoe smoother. By adjusting the length difference between the first and second elastic parts, this design can better adapt to wearers with different foot shapes. For example, for wearers with high insteps, the longer first elastic part can provide better adaptability and comfort. Because the first elastic part is close to the heel and is relatively long, its distribution inside the shoe is more even, which helps reduce the pressure or discomfort that the wearer may feel when putting on the shoe.

[0020] In the sixth technical solution and related embodiments, this flexible, easy-to-wear shoe achieves lateral support and adjustment by setting an elastic element on each side of the upper. The two elastic elements are located on the left and right sides of the upper, providing bilateral support. This design ensures that the shoe fits the wearer's foot shape securely, especially on the sides, providing additional support and stability. The dual-sided elastic elements distribute pressure more evenly across the sides of the shoe, helping to reduce discomfort caused by excessive localized pressure and improving comfort. Different wearers have different foot shapes, particularly in foot width. The dual-sided elastic element design can adapt to different foot widths, providing a more personalized wearing experience. When the wearer walks or engages in other activities, the dual-sided elastic elements work together to effectively resist external impacts and torsional forces, maintaining shoe stability and protecting the wearer's feet.

[0021] In the seventh technical solution and related embodiments, the elastic component made of a highly elastic material has excellent elasticity and resilience. This means that the elastic component can easily stretch when subjected to external force and then quickly return to its original state, ensuring that the shoe always fits the wearer's foot shape closely. Highly elastic materials generally have excellent durability and fatigue resistance, and the elastic component can maintain its original elasticity and function even under prolonged use or frequent external force, extending the lifespan of the shoe.

[0022] In the eighth technical solution and related embodiments, this type of flexible, easy-to-wear shoe connects the elastic element to the shoe upper by means of sewing, bonding, or snap-fitting, making it less likely to fall off. Attached Figure Description

[0033] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0034] See Figures 1 to 3 ,like Figure 1 and Figure 2 As shown, a flexible, easy-to-wear shoe includes a shoe body 1.

[0035] The shoe body 1 includes a sole 2, an upper 3, and an elastic element 4.

[0036] The sole (2) is a conventional structure that directly contacts the ground. Its structure typically includes the outsole, midsole, and heel. The outsole primarily serves to prevent slipping, provide abrasion resistance, and protect the foot, requiring good physical and chemical properties. The midsole mainly provides cushioning and support, reducing impact on the foot. The heel provides additional support and stability, especially during walking or running.

[0037] The upper 3, which is the outer part of the shoe, primarily functions to wrap around the foot and is located above the sole 2. It is typically composed of various materials, such as fabric and synthetic materials. The upper 3 and the sole 2 are connected through specific processes and structures to ensure the stability and comfort of the shoe.

[0038] The upper 3 includes a forefoot portion 5, a heel portion 6, and a connecting portion 7, all connected to the sole 2. The connecting portion 7 is close to the sole 2 and connects the forefoot portion 5 and the heel portion 6 near the lower end of the sole 2. The forefoot portion 5 and the heel portion 6 are separated from each other away from the upper end of the sole 2.

[0039] Specifically, the forefoot portion 5 includes the entire upper 3 except for the heel portion 6 and the connecting portion 7, and its range corresponds to the area from the toes to the instep. The lower edge of the forefoot portion 5 is bonded to the sole 2. The heel portion 6 corresponds to the heel of the foot and covers both sides of the heel; the lower edge of the heel portion 6 is also bonded to the sole 2. The connecting portion 7 is close to the sole 2 and connects to the lower ends of the forefoot portion 5 and the heel portion 6. The forefoot portion 5 and the heel portion 6 are connected by the connecting portion 7 near the lower end of the sole 2, and separate from each other away from the upper end of the sole 2. This ensures that the heel portion 6 does not completely detach from the forefoot portion 5 and still provides support for the foot.

[0040] The heel portion 6 is adapted to switch between a first state and a second state under the action of external force, such as Figure 1 As shown, when the heel part 6 is in the first state, it is close to the forefoot part 5 and cooperates with the forefoot part 5 to form a complete shoe opening 11, as shown. Figure 2 As shown, when the heel portion 6 is in the second state, it moves away from the forefoot portion 5, causing the shoe opening 11 to open. Specifically, in the normal state, the heel portion 6 and the forefoot portion 5 cooperate to form the shoe opening 11. Based on the characteristics of the upper material 3, it has good deformation characteristics. When the upper part of the heel portion 6 is subjected to an external force away from the forefoot portion 5, it folds backward and deforms, opening the shoe opening 11, making it easier for the wearer's foot to enter the shoe cavity. It should be noted that when the heel portion 6 switches from the first state to the second state, the lower part of the heel portion 6 and the connecting part 7 do not change. The deformation of the upper part of the heel portion 6 is achieved based on the characteristics of its material.

[0041] Elastic element 4, such as Figures 1 to 3 As shown, the elastic element 4 includes a first elastic portion 8, a second elastic portion 9, and an elastic bottom 10. The first elastic portion 8 connects to the heel portion 6, the second elastic portion 9 connects to the forefoot portion 5, and the elastic bottom 10 connects to the connecting portion 7. Specifically, the elastic element 4 is fixedly installed on the shoe upper 3 by sewing, gluing, or snapping, making it difficult to fall off. In this embodiment, the elastic element 4 has a U-shaped structure, with the first elastic portion 8 and the second elastic portion 9 forming the two sides of the U-shaped structure, and the elastic bottom 10 forming the bottom of the U-shaped structure. When there is no external force, the opening of the U-shaped structure is closed, and the first elastic portion 8 is close to the second elastic portion 9; when there is an external force, the opening of the U-shaped structure opens, and the first elastic portion 8 moves away from the second elastic portion 9. In this embodiment, the elastic element 4 is inclinedly disposed on the forefoot portion 5, the heel portion 6, and the connecting portion 7, with the opening direction of its U-shaped structure forming an angle with the extension direction of the sole 2 and extending obliquely upward. The length of the first elastic portion 8 is greater than the length of the second elastic portion 9. The length of the second elastic part 9 is approximately half the length of the first elastic part 8. The longer first elastic part 8, after elastic deformation, extends a greater distance, allowing the shoe opening 11 to open wider, facilitating the wearer's foot entering the shoe's interior. However, because the second elastic part 9 connects to the forefoot part 5, its elastic deformation distance is smaller; the forefoot part 5 remains almost unchanged as the shoe opening 11 widens. Simultaneously, the end of the second elastic part 9 is arc-shaped and bends towards the first elastic part 8. This means the first elastic part 8 does not need to rebound to a completely closed state with the second elastic part 9. Even when the end of the second elastic part 9 is attached to the first elastic part 8, the portion of the second elastic part 9 near the elastic bottom 10 remains separate from the first elastic part 8, thus reducing the rebound distance of the first elastic part 8.

[0042] There are two elastic components 4, one on each side of the shoe upper. The elastic components 4 are made of a highly elastic material. The selection of this material requires excellent elasticity and resilience. This means that the elastic component 4 can easily stretch under external force and then quickly return to its original state, ensuring the shoe always fits the wearer's foot shape closely. Highly elastic materials typically have excellent durability and fatigue resistance, allowing the elastic component 4 to maintain its original elasticity and function even under prolonged use or frequent external force, extending the shoe's lifespan. Specifically, high-elastic materials can be selected from materials with good elastic properties such as polyurethane (PU), natural rubber, or thermoplastic elastomers (TPE).

[0043] The elastic element 4 connects the forefoot portion 5, the heel portion 6, and the connecting portion 7. The elastic element 4 is adapted to unfold under external force, allowing the heel portion 6 to enter a second state. Once the external force is removed, the elastic element 4 rebounds and returns to its original position, allowing the heel portion 6 to return to its first state. Specifically, the first elastic portion 8 is adapted to unfold under external force acting away from the forefoot portion 5. The first elastic portion 8, with its elastic bottom 10 as a fulcrum, moves away from the second elastic portion 9, allowing the heel portion 6 to be in the second state. When the external force acting away from the forefoot portion 5 is removed, the first elastic portion 8 rebounds and returns to its original position, moving closer to the second elastic portion 9, allowing the heel portion 6 to return to its first state. Figure 3 As shown, when an external force is applied to the top of the first elastic member 4 away from the second elastic part 9, the first elastic part 8 elastically deforms away from the second elastic part 9, and the opening of the U-shaped structure of the elastic member 4 opens. At this time, the heel part 6 folds away from the forefoot part 5, and the heel part 6 switches to the second state, allowing the wearer's foot to easily enter the shoe cavity through the open shoe opening 11. When the shoe is put on, the first elastic part 8 elastically returns to its original position, wrapping the wearer's foot and providing sufficient support for walking. When it is necessary to take off the shoe, the wearer's foot applies a force to the first elastic part 8 away from the forefoot part 5, causing the first elastic part 8 to elastically deform, and the opening of the U-shaped structure of the elastic member 4 opens, allowing the wearer's foot to easily leave the shoe cavity. At this time, the first elastic part 8 elastically returns to its original position, moving closer to the second elastic part 9, and the heel part 6 moves closer to the forefoot part 5, returning to the first state.

[0044] In this embodiment, the elastic element 4 includes a first elastic part 8, a second elastic part 9, and an elastic bottom 10. This structure allows the heel part 6 to open easily when the shoe is subjected to external force, thereby forming a larger shoe opening 11, which greatly improves the convenience of putting on and taking off the shoe. The rebound and recovery performance of the elastic element 4 allows the shoe to automatically return to its original state after the external force is removed, that is, the heel part 6 and the forefoot part 5 cooperate to form a complete shoe opening 11. This feature not only ensures the structural stability of the shoe, but also ensures the comfort and safety of the shoe when worn. By using the elastic bottom 10 as a fulcrum, the first elastic part 8 can move away from the second elastic part 9 when subjected to external force, thereby opening the heel part 6 and making the opening and closing action of the shoe smoother.

[0045] In this embodiment, the U-shaped structure design gives the elastic element 4 excellent structural stability. This structure effectively disperses external forces, such as those generated when the wearer puts on or takes off shoes or walks, thus ensuring that the elastic element 4 can maintain its shape and function for a long time. U-shaped structures generally have good elastic properties. This allows the elastic element 4 to easily unfold when subjected to external force, making it convenient for the wearer to put on or take off shoes; and after the external force disappears, the elastic element 4 can quickly return to its original state, maintaining the stability of the shoe. Due to the characteristics of the U-shaped structure, the elastic element 4 can adapt to different foot shapes and foot structures. Whether the wearer has wide feet or a high instep, this structure can adapt to a certain extent and provide a comfortable wearing experience. At the same time, the U-shaped structure is relatively simple and easy to manufacture and process.

[0046] In this embodiment, due to the upward-sloping design of the opening of the elastic element 4, the foot can more easily enter the shoe along this slope when the wearer tries to put it on. Similarly, the foot can easily move out in this direction when taking off the shoe. The sloping design helps reduce friction between the foot and the shoe upper, especially during the process of putting on and taking off the shoe, which further increases the ease of putting on and taking off the shoe. Due to the sloping design, the pressure points of the elastic element 4 on the shoe upper are more evenly distributed, which helps reduce discomfort or pressure that the wearer may feel when putting on and taking off the shoe. This sloping design takes into account ergonomics and foot anatomy, allowing the shoe to conform to the curve of the foot when worn, providing excellent comfort and support. At the same time, this sloping design not only considers practicality but also aesthetics. The streamlined U-shaped sloping design makes the shoe look more stylish and beautiful, meeting the aesthetic needs of modern people.

[0047] In this embodiment, because the first elastic part 8 is connected to the heel part 6 and is relatively long, it can provide stronger support when the wearer puts on the shoe, ensuring the stability of the shoe, especially at the heel part 6. Although the first elastic part 8 is relatively long, its design near the heel part 6 makes it easier for the foot to enter the shoe when the wearer tries to put it on. At the same time, when it is necessary to take off the shoe, the longer length of the first elastic part 8 can provide more room for elastic deformation, making the process of taking off the shoe smoother. By adjusting the length difference between the first elastic part 8 and the second elastic part 9, this design can better adapt to wearers with different foot shapes. For example, for wearers with high insteps, the longer first elastic part 8 can provide better adaptability and comfort. Because the first elastic part 8 is close to the heel part 6 and is relatively long, its distribution inside the shoe is more even, which helps to reduce the pressure or discomfort that the wearer may feel when putting on the shoe.

[0048] In this embodiment, the flexible, easy-on / off shoe achieves lateral support and adjustment by incorporating an elastic element 4 on each side of the upper. The two elastic elements 4 are located on the left and right sides of the upper, providing bilateral support. This design ensures the shoe fits snugly to the wearer's foot shape, providing additional support and stability, especially on the sides. The dual elastic elements 4 distribute pressure more evenly across the sides of the shoe, reducing discomfort caused by excessive localized pressure and improving comfort. Different wearers have different foot shapes, particularly in foot width. The dual elastic elements 4 design accommodates foot widths, providing a more personalized wearing experience. When the wearer walks or engages in other activities, the dual elastic elements 4 work together to effectively resist external impacts and torsional forces, maintaining shoe stability and protecting the wearer's feet.

[0049] In this embodiment, the elastic opening and closing easy-to-wear shoe design achieves the easy-to-wear function of the shoe through the elastic element 4, while ensuring the comfort and stability of the shoe. The elastic element 4 connects the forefoot part 5 and the heel part 6 of the shoe, realizing the separation design of the two parts. This design gives the forefoot part 5 and the heel part 6 elastic characteristics. When the wearer is ready to put on the shoe, the elastic element 4 can easily unfold, making the shoe opening 11 wider, making it easier for the wearer to put their foot into the shoe. Once the wearer's foot is inside the shoe, the elastic element 4 will quickly return to its original position. Its elasticity and resilience help the shoe fit the curve of the wearer's foot closely, providing necessary support and reducing foot sway during walking or running and jumping, thereby ensuring the stability of the shoe in various movements. When the wearer is ready to take off the shoe, the elastic element 4 unfolds again, making it easy for the foot to come out of the shoe. Subsequently, the elastic element 4 will automatically return to the tightened state, making the shoe opening 11 narrow and return to its original position. The entire elastic opening and closing process of the shoe opening 11 simplifies the process of putting on and taking off the shoe. This design allows the shoe to adapt to changes in the wearer's foot shape during on / off, avoiding the compression or discomfort that can occur with traditional shoes. This simple yet efficient design avoids the use of complex moving parts, making the shoe both practical and stylish. The use of the elastic element 4 also helps cushion the impact on the feet during walking or exercise, reducing fatigue and discomfort. Although the upper ends of the forefoot 5 and heel 6 are separate, the connecting part 7 near the sole 2 connects the lower ends of the forefoot 5 and heel 6, and their connection with the elastic element 4 ensures the stability and support of the shoe during wear. At the same time, this separate design also gives the shoe a unique line and sense of layering, which, combined with the decorative design of the elastic element 4, creates a shoe that is both comfortable and fashionable.
