Description

Technical Field

[0001] This application relates to the field of footwear, specifically to a type of footwear. Background Technology

[0002] With societal development, people have increasingly higher functional demands for shoes. Current shoe models are typically based on shoe length, but feet of the same length can vary in width, arch height, and instep thickness, requiring the same shoe model to have an upper that adapts to different foot shapes. Sometimes, frequent shoe removal is necessary for different occasions, necessitating easy on and off; other times, prolonged standing or walking requires relief from foot pressure. Some current shoes use Velcro to adjust the tightness, but repeated use of Velcro weakens its adhesion, making them prone to slipping off and affecting gait or even causing falls. Other shoes feature a tongue, which allows the foot to enter the shoe by moving it up or down. A knob on the outside of the upper corresponding to the tongue allows for tightening or loosening, securing the foot vertically. However, this method is cumbersome due to the tongue-moving mechanism and primarily focuses on vertical foot support, failing to provide adequate support in other directions, resulting in poor foot wrapping performance. The knob is located on the corresponding position on the tongue, which is located on the upper part of the forefoot. Placing the knob in this position affects the overall appearance of the shoe. Utility Model Content

[0003] The purpose of this application is to overcome the aforementioned defects or problems in the prior art and to provide a shoe with a quick-adjustable upper to accommodate different foot shapes and easy on and off.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] A shoe includes a sole, an upper, a heel, a connecting portion, and an elastic component. The upper and heel are respectively connected to the sole. The upper and heel are spaced apart at least on one of the inner and outer sides of the shoe. The elastic component includes a gear and an operating component. The connecting portion is connected to the top of the upper and surrounds the heel, connecting to the gear. The gear is mounted on the heel. The operating component has a limiting portion. The operating component is adapted to drive the gear to rotate and limit the gear by the limiting portion to tighten the connecting portion and reduce the gap, or to move relative to the gear in a direction away from the heel so that the limiting portion no longer limits the gear and loosens the connecting portion to increase the gap.

[0006] Furthermore, the upper and heel portion form the aforementioned gaps on the inner and outer sides of the shoe, respectively.

[0007] Furthermore, the intervals sequentially include a first interval, a second interval, and a third interval along the front-back direction of the shoe. A first side portion is provided between the first interval and the second interval, and a second side portion is provided between the second interval and the third interval. The connecting portion connects the top of the first side portion and the second side portion.

[0008] Furthermore, the connecting part includes a connecting strap and a traction rope, the connecting strap being connected to the top of the shoe upper, the first side, and the second side, and the traction rope connecting the connecting strap and the elastic assembly.

[0009] Furthermore, the heel portion includes a fixing component, which sequentially includes a first cushioning portion, a second cushioning portion, a first fixing portion, a second fixing portion, and a third fixing portion along the front-back direction of the shoe; the second fixing portion is located above the third fixing portion and is connected to the elastic component, and the second cushioning portion and the second fixing portion are correspondingly arranged.

[0010] Furthermore, it includes an insole that includes an upwardly projecting first protrusion located at a position corresponding to the metatarsal bone.

[0011] Furthermore, the insole includes an upwardly protruding second protrusion located at a position corresponding to the arch of the foot.

[0012] Furthermore, the insole includes a support member located at the bottom of the insole; the support member includes a first support portion, a second support portion, a third support portion, a fourth support portion, and a fifth support portion; the first support portion is located at a position corresponding to the arch of the foot, the second support portion and the third support portion extend forward from the inner and outer sides of the front end of the first support portion, respectively, and the fourth support portion and the fifth support portion extend backward from the inner and outer sides of the rear end of the first support portion, respectively.

[0013] Furthermore, the upper part of the sole is provided with a receiving cavity, and the insole is located in the receiving cavity.

[0014] Furthermore, the tightening component is a knob.

[0015] Compared with existing technologies, the above solution has the following beneficial effects:

[0016] In the first technical solution, the upper and heel form a gap on at least one of the inner or outer sides of the shoe. The elastic component includes a gear and an operating component, with the gear located in the heel. The elastic component tightens or loosens the connecting part, making the gap smaller or larger. A larger gap allows the foot to extend more easily; a smaller gap tightens the foot, preventing it from slipping off. No adjustment of the tongue or Velcro is needed when putting on or taking off the shoe, making it convenient. The gap is located on one of the inner or outer sides of the shoe. Operating the elastic component to tighten the connecting part pulls the upper and heel towards each other, reducing the first gap. This movement of the upper and heel improves the shoe's front-to-back fit. The connecting part connects to the top of the upper and wraps around the connecting gear at the heel. When the connecting part is tightened by the elastic component, the annular area formed by the connecting part decreases. The top of the upper is pulled by the connecting part in the direction of the decreasing annular area, causing the entire upper to move from the periphery of the foot towards the inwards, improving the fit of more parts of the foot. By providing multi-directional support, the upper can better adapt to different foot shapes. Consumers' subjective perception of the shoe's appearance is primarily focused on the forefoot and arch areas. Elastic components are not placed in these areas; instead, they are placed in the heel area, where consumers have a lower perception of appearance, minimizing the impact of the elastic components on the overall appearance of the shoe.

[0017] The elastic band is easy to operate. An operating component drives a gear mechanism to rotate, which in turn limits the gear mechanism's position. The rotating gear mechanism tightens the connecting part, reducing the gap. As the operating component is adjusted, the upper and heel gradually increase their fit around the foot. When the shoe is adjusted to a comfortable position, adjustment stops, and the limiting part stops the gear mechanism, fixing the relative positions of the upper and heel. Moving the operating component relative to the gear mechanism away from the heel removes the limiting part from the gear mechanism, and the gear mechanism stops tightening the connecting part, widening the gap and allowing the foot to easily extend out of the shoe. This easy-to-use elastic band improves the ease of putting on and taking off the shoes.

[0018] The second technical solution involves creating gaps on the inner and outer sides of the shoe's upper and heel. When the elastic component is adjusted, these gaps on both sides decrease simultaneously, resulting in more even adjustment and improved foot support.

[0019] The third technical solution includes a first interval, a second interval, and a third interval sequentially along the front-to-back direction. A connecting part connects the tops of the first and second sides. When the elastic component tightens the connecting part, the connecting part pulls the upper, the first and second sides, and the heel towards each other, causing the first, second, and third intervals to decrease in size. The first, second, and third intervals are sequentially arranged along the front-to-back direction and located in multiple parts of the shoe, allowing for adjustment of the fit around multiple parts of the foot and reducing the accumulation of the upper when pulled by the connecting part. Multiple intervals also increase the shoe's breathability.

[0020] The fourth technical solution involves a connecting section comprising a connecting strap and a traction rope. The connecting strap has a large surface area, which reduces pressure on the foot and improves foot comfort. The traction rope is strong, increasing its lifespan; and its small size reduces the space required to house the traction rope in the gear components, thus reducing the overall volume of the tensioning assembly.

[0021] The fifth technical solution includes a fixing component in the heel area. This fixing component, arranged sequentially along the front-to-back direction of the shoe, comprises a first cushioning part, a second cushioning part, a first fixing part, a second fixing part, and a third fixing part. The second fixing part is located above the third fixing part and is connected to an elastic component. In this solution, the elastic component is located at the top of the heel area for easy adjustment and to prevent damage from impacts during walking if the elastic component is located at the bottom of the heel. The first, second, and third fixing parts enhance the stability of the heel area. The first and second cushioning parts in the fixing component separate the harder components from the body and provide cushioning to maintain foot comfort.

[0022] The sixth technical solution is that the shoe includes an insole, which includes an upwardly protruding first protrusion located at the position corresponding to the metatarsal bone. When the human body walks and stands, the core force-bearing area of ​​the foot is mainly concentrated on the metatarsal bone. Setting the upwardly protruding first protrusion at the position corresponding to the metatarsal bone increases the force-bearing area of ​​the metatarsal bone, reduces the unit pressure, and better maintains foot health.

[0023] The seventh technical solution involves an upward-protruding second ridge at the arch position of the insole. The stress on the human foot arch is distributed in a triangular pattern: heel-outer arch-forefoot. This second ridge supports the arch, increasing the stress on the outer arch and distributing pressure from the inner arch and plantar fascia to the heel-outer arch-forefoot, reducing pressure on the plantar fascia and preventing damage. The combination of the first and second ridges alleviates localized pain points and improves foot stability, enhancing comfort during prolonged standing or walking.

[0024] The eighth technical solution includes an insole comprising a support member located at the bottom of the insole, below the first and second protrusions. The first support member is positioned corresponding to the arch of the foot. The second and third support members extend forward from the inner and outer sides of the front end of the first support member, respectively. The fourth and fifth support members extend backward from the inner and outer sides of the rear end of the first support member, respectively. This distributes the pressure of the foot to the inner and outer sides of the forefoot and the inner and outer sides of the heel, reducing pressure in various areas and improving wearing comfort. Furthermore, the fourth and fifth support members are located on the inner and outer sides of the heel, reducing pressure in various parts of the foot without affecting the contact between the heel and the elastic sole.

[0025] The ninth technical solution is that the upper part of the sole, near the foot, has a receiving cavity, and the insole is located in the receiving cavity. The receiving cavity restricts the insole, prevents the insole from moving, and improves wearing stability.

[0026] The tenth technical solution is to use a knob as the tensioning component. The knob is small in size, easy to operate, and enhances the overall aesthetics and ease of operation. Attached Figure Description

[0041] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0042] Example 1

[0043] See Figure 1 , Figure 1 A schematic diagram of a shoe is shown. Shoe 1 includes a sole 2, an upper 3, a heel 4, a connecting part 5, and an elastic component 6. The upper 3 and heel 4 are respectively connected to the sole 2, and the sole 2, upper 3, and heel 4 form a space for the foot. The upper 3 is made of a soft fabric to improve wearing comfort. In this embodiment, the upper 3 and heel 4 form a gap 7 on the outer side of the shoe. In other embodiments, the upper 3 and heel 4 may form a gap 7 on the inner side of the shoe 1. The gap 7 is a hollow structure, providing space for movement between the upper 3 and heel 4. The orientation in this embodiment is as follows... Figure 1 As shown, the side where the little finger is located is the outer side, and the side where the thumb is located is the inner side.

[0044] The elastic component 6 is located on the rear side of the heel portion 4, such as... Figure 7As shown, the tensioning assembly 6 includes a gear 61 and an operating member 62. The connecting portion 5 connects to the top of the upper 3 and wraps around the outer rear side of the heel portion 4, connecting to the gear 61 of the tensioning assembly 6 on the outer rear side of the heel portion 4. The tensioning assembly 6 is located on the outer rear side of the heel portion 4 for easy operation and minimal impact on the overall appearance of the shoe 1. The connecting portion 5 is located at the top of the upper 3, forming a passage for foot entry and exit between it and the heel portion 4. A gap 7 is located between the upper 3 and the heel portion 4, with the connecting portion 5 connecting the top of the upper 3 and the gear 61 outside the heel portion 4, and the connecting portion 5 is located at the upper part of the gap 7.

[0045] The operating component 62 is equipped with a limiting part. After the foot is inserted into the shoe 1, the operating component 62 is operated. The operating component 62 drives the gear component 61 to rotate. When the gear component 61 rotates, it tightens the connecting part 5. The limiting part limits the gear component 61, preventing the connecting part 5 from returning to its original position. Under the tightening of the gear component 61, the connecting part 5 drives the upper 3 and the heel 4 to move towards each other along the interval 7. The interval 7 becomes smaller, and the space for the foot formed by the sole 2, upper 3, and heel 4 becomes smaller, thus wrapping the foot. The upper 3 is made of soft fabric. Under the pull of the connecting part 5, the upper 3 and the heel 4 move towards each other in the front-back direction, improving the front-back wrapping of the foot. In addition to driving the upper 3 and the heel 4 to move towards each other, the connecting part 5 also reduces the opening for the foot to enter and exit through the foot. The connecting part 5 drives the upper 3 to move in the direction of narrowing opening, thus wrapping the foot in all directions. This design provides a three-dimensional wrap around the foot, enhancing its support and better adapting to various foot widths, arch heights, and instep thicknesses.

[0046] The operating member 62 moves relative to the gear member 61 in a direction away from the heel portion 4 so that the limiting part no longer limits the gear member 61, thereby loosening the connecting part 5 and increasing the gap 7. In other embodiments, the operating member 62 may also move in other directions so that the limiting part does not limit the gear member 61. After the limiting part no longer limits the gear member 61, the gear member 61 is not fixed to the connecting part 5. After the connecting part 5 is loosened, the gap 7 increases, the space formed by the sole 2, the upper 3, and the heel portion 4 increases, and the foot passage formed by the connecting part 5 and the heel portion 4 increases, making it easier for the foot to exit the shoe 1. The operating member 62 conveniently reduces the space inside the shoe 1 to wrap the foot and increases the space inside the shoe 1 to facilitate the foot's extension, improving the ease of putting on and taking off the shoe.

[0047] Example 2

[0048] The difference between Example 2 and Example 1 lies in the following:

[0049] See Figure 2 , Figure 2The upper 3 and heel 4 form gaps 7 on the inner and outer sides of the shoe 1, respectively. There are three gaps 7, sequentially named first gap 71, second gap 72, and third gap 73 along the front-to-back direction of the shoe 1. That is, the inner side of the shoe 1 includes the first gap 71, second gap 72, and third gap 73 along the front-to-back direction; the outer side of the shoe 1 also includes the first gap 71, second gap 72, and third gap 73 along the front-to-back direction. When the elastic component is adjusted, the gaps on both the inner and outer sides decrease simultaneously, resulting in more even adjustment and improved foot support. A first side portion 81 is provided between the first gap 71 and the second gap 72, and a second side portion 82 is provided between the second gap 72 and the third gap 73. A connecting portion 5 connects the tops of the first side portion 81 and the second side portion 82. Figure 2 As shown, the connecting part 5 includes a connecting strap 51 and a traction rope 52. The connecting strap 51 connects the top of the upper 3, the top of the first side 81 and the second side 82. The traction rope 52 connects the rear end of the connecting strap 51 to the elastic component 6 of the heel part 4. The connecting strap 51 has a large surface area, reducing the pressure on the foot. When the elastic component 6 of the heel part 4 tightens the connecting part 5, the first interval 71, the second interval 72 and the third interval 73 all become smaller. The upper 3, the first side 81 and the second side 82 wrap around the foot under the action of the connecting part 5. The intervals set in multiple parts of the shoe 1 reduce the accumulation between the fabrics of the upper 3, more accurately control the wrapping of the upper 3, and make it more comfortable to wear. In this embodiment, the elastic component 6 is a knob. The knob can realize stepless adjustment of the connecting part 5, thereby accurately controlling the tightness of the upper 3 to adapt to various foot sizes.

[0050] See Figure 3 , Figure 3 An exploded view of the fixing component 40 is shown. The fixing component 40 is located at the heel portion 4 and is used to fix the elastic component 6. The fixing component 40 includes, in sequence along the front-to-back direction of the shoe 1, a first cushioning portion 41, a second cushioning portion 42, a first fixing portion 43, a second fixing portion 44, and a third fixing portion 45. The elastic component 6 is subjected to significant forces during use; therefore, the fixing component 40 is provided when the elastic component 6 is connected to the heel portion 4. The high strength of the fixing component 40 prevents damage to the heel portion 4. The third fixing portion 45 of the fixing component 40 has a shape corresponding to the heel of the foot, serving to fix the heel portion 4 and prevent deformation. The second fixing portion 44 is located above the third fixing portion 45 and is connected to the elastic component 6. The elastic component 6 is located above the heel portion 4, facilitating operation and reducing the risk of damage. The first fixing portion 43 improves the support of the fixing component 40 and better fixes the second fixing portion 44, preventing the second fixing portion 44 from falling off. The second buffer part 42 is provided correspondingly to the second fixing part 44 to reduce the pressure exerted by the second fixing part 44 on the foot. The first buffer part 41 is provided correspondingly to the heel of the foot to prevent the heel from contacting the strong fixing part and reduce discomfort.

[0051] See Figure 4 and 6 The shoe 1 includes an insole 9. A receiving cavity 21 for accommodating the insole 9 is provided on the upper surface of the sole 2. The shape of the receiving cavity 21 is adapted to the insole 9 to prevent the insole 9 from moving within the shoe, thus improving stability during walking. In this embodiment, the sole 2 includes a non-slip and wear-resistant rubber outsole and a highly resilient midsole, providing excellent resilience and non-slip performance, suitable for prolonged standing and walking. The insole 9 includes an upwardly protruding first protrusion 91 and a second protrusion 92. The first protrusion 91 is located at a position corresponding to the metatarsal bones, preferably at a position corresponding to the anterior end of the metatarsal bones. The upward protrusion of the first protrusion 91 increases the pressure area on the foot, reduces foot pressure, and improves foot comfort. The second protrusion 92 is located at a position corresponding to the arch of the foot, preferably at a position corresponding to the medial side of the arch. The second protrusion 92, by supporting the medial side of the arch, redistributes the pressure originally concentrated in the plantar fascia to the heel, the lateral side of the arch, and the forefoot, reducing pressure on the plantar fascia. The combined action of the first protrusion 91 and the second protrusion 92 redistributes pressure on the foot, reducing discomfort in the metatarsals and plantar fascia.

[0052] See Figure 5 The insole 9 has a support member 10 at its bottom, which includes a first support part 11, a second support part 12, a third support part 13, a fourth support part 14, and a fifth support part 15. The first support part 11 is located at the position corresponding to the arch of the foot. The second support part 12 and the third support part 13 extend from the inner and outer sides of the front end of the first support part 11 toward the forefoot, respectively. The fourth support part 14 and the fifth support part 15 extend from the inner and outer sides of the rear end of the first support part 11 toward the heel 4, respectively. The support member 10 distributes pressure to the inner and outer sides of the forefoot and heel, reducing pressure in each area and improving comfort. The fourth support part 14 and the fifth support part 15 are located on the inner and outer sides of the heel, so they do not affect the contact between the heel and the high-resilience material of the sole 2.

[0053] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
