Description

Technical Field

[0001] This utility model relates to the field of slipper technology, and in particular to a slipper with an airbag cushioning structure. Background Technology

[0002] Slippers are a type of lightweight footwear with an open heel and a toe box. The overall design prioritizes lightness and comfort. They are typically made of soft, breathable leather, fabric, or plastic, and usually have flat soles, requiring no laces or other fastening devices.

[0003] Traditional slippers are widely used because of their simple structure, low cost, and ease of putting on and taking off. However, they were originally designed for home use, short-term use, and lightweight purposes, which limits their functionality and comfort.

[0004] Traditional slippers typically have a single, flat sole and lack a design specifically for the human arch. Wearing them for extended periods can easily lead to arch fatigue, collapse, or pain, especially for people with flat feet or high arches. Traditional slippers also typically have thin soles and lack a cushioning layer or elastic material, which cannot effectively absorb the impact of the ground on the soles of the feet when walking. Wearing them for a long time may lead to plantar fascia strain, increased stress on the knees or lumbar spine, and cause foot pain, knee pain, or even back pain. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slipper with an airbag cushioning structure, which can improve the cushioning performance of the slipper sole, reduce the impact of the sole on the foot when walking, and improve the wearing comfort of the slipper.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a slipper with an airbag cushioning structure, comprising a sole and an upper, the two sides of the upper being fixed to the left and right sides of the front part of the sole, a recessed mounting groove forming on the upper surface of the sole, a cushioning insole being provided in the mounting groove, an airbag cushioning structure being provided on the upper surface of the cushioning insole, the airbag cushioning structure comprising multiple airbags, each airbag being distributed at intervals on the surface of the cushioning insole, and an air tube connecting two adjacent airbags to form a connected airbag cushioning structure composed of multiple airbags, wherein the ratio between the inner diameter d1 of the air tube and the maximum outer diameter d2 of the airbag satisfies the condition: d1∶d2=1∶4~10.

[0007] In a further technical solution, the projected shape of the airbag is circular, elliptical, or rectangular, with a maximum outer diameter of 6mm to 15mm and a protrusion height h of 2mm to 8mm.

[0008] In a further technical solution, the surface of the cushioning insole is also provided with a forefoot support pad, an arch support pad, and a heel support pad. The forefoot support pad, arch support pad, and heel support pad are each elastically set. The forefoot support pad is located in the middle of the front side of the cushioning insole; the arch support pad is located in the inner side of the middle of the cushioning insole; and the heel support pad is located in the middle of the rear side of the cushioning insole. The protrusion height of the forefoot support pad and the heel support pad is slightly smaller than the protrusion height of the air bladder; and the protrusion height of the arch support pad is slightly larger than the protrusion height of the air bladder.

[0009] In a further technical solution, the cushioning insole includes a bottom pad layer and a soft rubber surface layer. The soft rubber surface layer is made of silicone material and is formed into multiple semi-circular shells. A semi-tube shell is formed between two adjacent semi-circular shells. The two ends of the semi-tube shell are connected to the shell cavity of the corresponding semi-circular shell. The soft rubber surface layer is bonded or fused to the bottom pad layer. The bonding surface of the bottom pad layer surrounds each semi-circular shell and each semi-tube shell to form an air bladder and an air tube.

[0010] In a further technical solution, the soft rubber surface layer is also formed with a first convex shell, a second convex shell, and a third convex shell. The first convex shell has a circular projection shape and a first shell cavity is formed inside it. The first shell cavity and the adhesive surface of the base layer surround it to form a first cushioning airbag with cushioning performance, which is used as a foot support pad. The second convex shell has a crescent shape projection shape and a second shell cavity is formed inside it. The second shell cavity and the adhesive surface of the base layer surround it to form a second cushioning airbag with cushioning performance, which is used as an arch support pad. The third convex shell has an elliptical shape projection shape and a third shell cavity is formed inside it. The third shell cavity and the adhesive surface of the base layer surround it to form a third cushioning airbag with cushioning performance, which is used as a heel support pad.

[0011] In a further technical solution, the airbag cushioning structure includes multiple airbags with a circular projection shape. Each airbag is distributed at intervals along the edge of the cushioning insole to form a closed-track distribution airbag cushioning structure. The forefoot support pad and heel support pad are located on the inner side of the airbag cushioning structure, and the arch support pad is located on the outer side of the airbag cushioning structure.

[0012] In a further technical solution, there are 2 to 5 additional air bladders on the rear side of the foot support pad, and the two sides of these air bladders are connected to the adjacent air bladders on the left and right sides through air tubes.

[0013] In a further technical solution, the inner side of the shoe upper is provided with an instep cushioning structure, which includes multiple airbag cushioning combinations. The airbag cushioning combinations are arranged in an array, and each airbag cushioning combination includes 1 to 3 airbags. Adjacent airbags in the same airbag cushioning combination are connected by another air tube to form a connected airbag cushioning combination.

[0014] In a further technical solution, the instep cushioning structure includes two rows of airbag cushioning assemblies. The row of airbag cushioning assemblies on the front includes two sets of three-airbag assemblies consisting of three airbags each, and one set of two-airbag assemblies consisting of two airbags each. The two sets of three-airbag assemblies are located on the left and right sides respectively, and the two-airbag assemblies are located in the middle position. The row of airbag cushioning assemblies on the rear includes three sets of two-airbag assemblies consisting of two airbags each, and two sets of single-airbag assemblies consisting of one airbag each. The two-airbag assemblies and single-airbag assemblies are alternately arranged in the lateral direction. One set of two-airbag assemblies is located in the middle position of the inner side of the shoe upper.

[0015] In a further technical solution, the projected shape of each airbag in the front row of airbag cushioning assemblies is circular; the projected shape of each airbag in the rear row of airbag cushioning assemblies is elliptical, and the long diameter of these airbags is arranged along the front-rear direction of the shoe upper.

[0016] The advantages of this invention compared to the prior art after adopting the above structure are: 1. The airbag cushioning structure of the sole disperses the impact force through multiple connected airbags and air tubes, which can reduce the vibration of the ground on the sole of the foot when walking and improve comfort.

[0017] 2. It is equipped with support pads for the sole, arch, and heel, which fit the key parts of the foot, providing both cushioning and stable support to reduce arch fatigue or injury.

[0018] 3. The airbag body is made by overlapping a base layer and a soft rubber surface layer, which is simple to manufacture and not easy to leak; the airbag size and air tube ratio are scientifically designed to balance cushioning effect and durability.

[0019] 4. The air cushion combination on the inside of the shoe upper covers the instep, distributing pressure on the instep, avoiding friction or compression, and improving the all-around wearing experience.

[0020] 5. With its multi-layered cushioning and support design, it is suitable for different foot shapes and daily and short-distance scenarios, reducing the risk of fatigue or pain from prolonged wear. Attached Figure Description

[0027] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, a slipper with an airbag cushioning structure includes a sole 1 and an upper 2. The two sides of the upper 2 are fixed to the left and right sides of the front part of the sole 1. A recessed mounting groove 10 is formed on the upper surface of the sole 1. A cushioning insole 3 is provided in the mounting groove 10. An airbag cushioning structure 4 is provided on the upper surface of the cushioning insole 3. The airbag cushioning structure 4 includes multiple airbags 41. Each airbag 41 is distributed at intervals on the surface of the cushioning insole 3. An air tube 42 is connected between two adjacent airbags 41 to form a connected airbag cushioning structure 4 composed of multiple airbags 41. The ratio between the inner diameter d1 of the air tube 42 and the maximum outer diameter d2 of the airbag 41 satisfies the condition: d1∶d2=1∶7.

[0029] By incorporating a connected airbag cushioning structure on the upper surface of the cushioning insole, and designing a ratio between the inner diameter d1 of the air duct and the maximum outer diameter d2 of the airbag, the system ensures both the elastic deformation space of the airbag itself and the balanced transmission of air pressure through the appropriately sized air duct. When the foot is pressed down, any airbag deforms under pressure, and the gas can quickly diffuse to adjacent airbags through the air duct, making the pressure distribution of the entire cushioning structure more uniform and avoiding localized stress concentration. At the same time, the connected structure enhances the overall deformation recovery capability, effectively absorbing and dispersing the vertical impact force of the ground on the sole of the foot during walking, significantly reducing the load on the plantar fascia, joints, and spine caused by long-term impact, and reducing the risk of foot pain, knee pain, and back pain.

[0030] Specifically, the airbag body 41 has a circular projection shape, with a maximum outer diameter of 12 mm and a protrusion height h of 4 mm.

[0031] Specifically, the surface of the cushioning insole 3 is also provided with a forefoot support pad 5, an arch support pad 6, and a heel support pad 7. The forefoot support pad 5, the arch support pad 6, and the heel support pad 7 are elastically arranged. The forefoot support pad 5 is located in the middle of the front side of the cushioning insole 3; the arch support pad 6 is located in the inner side of the middle of the cushioning insole 3; and the heel support pad 7 is located in the middle of the rear side of the cushioning insole 3. The protrusion height of the forefoot support pad 5 and the heel support pad 7 is slightly less than the protrusion height of the air bladder 41; and the protrusion height of the arch support pad 6 is slightly greater than the protrusion height of the air bladder 41.

[0032] By adding differentiated elastic support pads to the surface of the cushioned insole, and specifically designing their positions and protrusion heights: the protrusion height of the forefoot support pad and heel support pad is slightly smaller than that of the air bladder, mainly playing an auxiliary cushioning role, conforming to the contact area between the forefoot and heel, and relieving concentrated pressure during the initial stepping; the protrusion height of the arch support pad is slightly larger than that of the air bladder, which can precisely conform to the natural curvature of the human arch, providing stable upward support for the arch, especially for people with flat feet or high arches, effectively maintaining the normal shape of the arch and avoiding arch collapse or excessive fatigue caused by long-term wear; the above support pads and air bladder cushioning structure work together to form a composite function of "distributed cushioning + focused support", which not only ensures the comfort of the entire foot, but also provides extra protection for vulnerable areas such as the arch.

[0033] Specifically, the cushioning insole 3 includes a bottom pad layer 301 and a soft rubber surface layer 302. The soft rubber surface layer 302 is made of silicone material. The soft rubber surface layer 302 is formed with multiple semi-circular shells 3021. A semi-tube shell 3022 is formed between two adjacent semi-circular shells 3021. The two ends of the semi-tube shell 3022 are connected to the shell cavity of the corresponding semi-circular shell 3021. The soft rubber surface layer 302 is bonded to the bottom pad layer 301. The bonding surface of the bottom pad layer 301 surrounds each semi-circular shell 3021 and each semi-tube shell 3022 to form an air bladder 41 and an air tube 42.

[0034] The soft rubber surface layer is made of flexible materials such as silicone. It is formed by molding a semi-circular shell and a semi-tube shell and bonding / fusion with the bottom pad layer to form a sealed airbag and air tube. This design not only simplifies the production process, but also improves the overall integrity and durability of the structure. At the same time, the elastic properties of silicone material further enhance the softness of the cushioning.

[0035] Specifically, the soft rubber surface layer 302 is also formed with a first convex shell, a second convex shell, and a third convex shell. The first convex shell is circular in shape and has a first shell cavity inside. The first shell cavity and the adhesive surface of the base layer 301 surround the first shell cavity to form a first cushioning airbag with cushioning performance, which is used as a foot support pad 5. The second convex shell is crescent-shaped in shape and has a second shell cavity inside. The second shell cavity and the adhesive surface of the base layer 301 surround the second shell cavity to form a second cushioning airbag with cushioning performance, which is used as an arch support pad 6. The third convex shell is elliptical in shape and has a third shell cavity inside. The third shell cavity and the adhesive surface of the base layer 301 surround the third cushioning airbag with cushioning performance, which is used as a heel support pad 7.

[0036] Specifically, the airbag cushioning structure 4 includes multiple airbags 41 with a circular projection shape. Each airbag 41 is distributed at intervals along the edge direction of the cushioning insole 3 to form a closed-track distribution airbag cushioning structure 4. The forefoot support pad 5 and the heel support pad 7 are located on the inner side of the airbag cushioning structure 4, and the arch support pad 6 is located on the outer side of the airbag cushioning structure 4.

[0037] Specifically, there are three additional airbags 41 on the rear side of the foot support pad 5. The two sides of these airbags 41 are connected to the adjacent airbags 41 on the left and right sides through air tubes 42.

[0038] Specifically, the inner side of the shoe upper 2 is provided with an instep cushioning structure, which includes multiple airbag cushioning assemblies 40. The airbag cushioning assemblies 40 are arranged in an array, and each airbag cushioning assembly 40 includes 1 to 3 airbags 41. Adjacent airbags 41 in the same airbag cushioning assembly 40 are connected by another air tube 42 to form a connected airbag cushioning assembly 40.

[0039] Specifically, the instep cushioning structure includes two rows of airbag cushioning assemblies 40. The row of airbag cushioning assemblies 40 located on the front includes two sets of three-bag assemblies consisting of three airbags 41, and one set of two-bag assemblies consisting of two airbags 41. The two sets of three-bag assemblies are located on the left and right sides respectively, and the two-bag assemblies are located in the middle position. The row of airbag cushioning assemblies 40 located on the rear includes three sets of two-bag assemblies consisting of two airbags 41, and two sets of single-bag assemblies consisting of one airbag 41. The two-bag assemblies and single-bag assemblies are alternately arranged in the lateral direction. One set of two-bag assemblies is located in the middle position of the inner side of the shoe upper 2.

[0040] Specifically, the projected shape of each airbag body 41 in the front row of airbag cushioning assemblies 40 is circular; the projected shape of each airbag body 41 in the rear row of airbag cushioning assemblies 40 is elliptical, and the long diameter of these airbag bodies 41 is arranged along the front-back direction of the shoe upper 2.

[0041] By setting up an array of airbag cushioning units on the inner side of the shoe upper, a cushioning protection layer is formed for the instep: the front row of airbag cushioning units can disperse the pressure on the toes and the front of the instep; the rear row of airbag cushioning units focuses on fitting the middle of the instep and the area near the ankle, avoiding the upper being too tight or the shoe upper rubbing and squeezing the instep during walking; furthermore, by differentiating the projected shapes of the front and rear airbags, the force adaptation of different areas is optimized - the round airbags evenly distribute the pressure, while the oval airbags extend longitudinally along the instep, better conforming to the natural curve of the human foot, improving the overall fit and comfort of wearing.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
