Description

Technical Field

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

[0002] Current shoe solutions on the market are relatively mature, mainly including Velcro, adjustable elastic straps, shoelaces, twist locks, and slip-on designs. Among them, the slip-on structure enables quick on and off by connecting the elastic upper to the heel, but due to its convenient design, it often results in insufficient ankle support from the heel.

[0003] In addition, existing technologies also include designs with outward-folding collars to further improve the efficiency of putting on and taking off shoes. However, in pursuit of this functionality, such designs usually require reducing the tightness between the heel and the upper, which weakens the heel's support for the foot, thus affecting wearing stability and comfort. Utility Model Content

[0004] The purpose of this application is to provide a shoe that facilitates the adjustment of the tightness at the heel.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] The first technical solution relates to a shoe, which includes an upper and a heel. The heel includes a support layer and an adjustment component. The support layer includes an opening, a deformable portion, and a heel portion sequentially from the shoe opening to the sole. The opening is turned outward at the heel opening, and the heel portion is shaped to fit the curve of the heel and tapers inward at the sole. The adjustment component includes a connector and an adjustment member. The adjustment member is fixed to the opening. The connector connects the adjustment member and the upper. The adjustment member is adapted to change the length of the connector to adjust the distance between the upper and the heel. The deformable portion is adapted to deform to accommodate the adjustment component's adjustment of the distance between the upper and the heel.

[0007] The second technical solution is based on the first technical solution, wherein the adjusting component includes an adjusting knob and a bottom buckle, the bottom buckle is fixed to the opening of the support layer, the bottom buckle includes a base and a connecting platform, the base is shaped to fit the opening, the connecting platform is fixedly connected to the base, and the adjusting knob is rotatably connected to the connecting platform.

[0008] The third technical solution is based on the first technical solution, wherein the opening conforms to the curve of the ankle, and the support layer has an arc-shaped protrusion at the opening, the arc-shaped protrusion being adapted to abut against the depression of the ankle.

[0009] The fourth technical solution is based on the second technical solution, wherein the connecting platform is provided with a buffer part, the side of the buffer part near the adjustment knob is adapted to abut against the adjustment knob, and the buffer part is hollow in the middle.

[0010] The fifth technical solution is based on the first technical solution, wherein the heel of the shoe further includes a connecting layer and a cushioning layer. The connecting layer wraps the outer surface of the support layer and is connected to the upper of the shoe. The connecting layer has a through hole. The bottom buckle is fixed to the support layer and extends out of the through hole to be rotatably connected to the adjustment knob. The cushioning layer wraps the inner surface of the support layer.

[0011] The sixth technical solution is based on the fifth technical solution, wherein the hardness of the support layer is greater than that of the connecting layer and the buffer layer, and the connecting layer and the buffer layer are connected by sewing.

[0012] The seventh technical solution is based on the fifth technical solution, wherein the bottom buckle is fixedly connected to the support layer by high-temperature melting.

[0013] The eighth technical solution is based on the second technical solution, wherein the adjustment knob is adapted to rotate on the outer surface of the heel of the shoe, one end of the connector is wrapped around the adjustment knob, and the other end is fixedly connected to the shoe surface.

[0014] The ninth technical solution is based on the eighth technical solution, wherein the number of the connectors is 2, and the connectors are symmetrically distributed on both sides of the shoe. One end of the two connectors is connected to the same adjustment knob, and the other end is connected to the shoe upper.

[0015] The tenth technical solution is based on the fifth technical solution, wherein the thickness of the buffer layer is greater than that of the support layer, and the buffer layer always wraps around the ankle when the adjustment component adjusts the tightness of the shoe heel.

[0016] The eleventh technical solution is based on the fifth technical solution, wherein the support layer is made of TPU material, the buffer layer is made of composite sponge mesh, and the connecting layer is made of mesh.

[0017] Compared with existing technologies, the above solution has the following beneficial effects:

[0018] In the first technical solution, the opening at the heel opening is turned outwards, so that when the foot applies downward pressure while wearing the shoe, the outward-turned design of the opening will decompose part of the downward pressure, causing the opening to open outwards. This eliminates the need for the user to manually open the opening when wearing the shoe, making it more convenient for the user to wear the shoe.

[0019] In the first technical solution, the shape of the heel part conforms to the curve of the heel and is tapered inward on the sole. This design is ergonomic, which allows the heel to better support the heel. Furthermore, the tapering of the heel part on the sole and the outward flipping of the opening allow the deformation part of the support layer to conform to the outward bending of the ankle, which is beneficial for better ankle support.

[0020] In the first technical solution, the adjusting component is fixed to the opening. When the adjusting component changes the length of the connecting component to adjust the distance between the upper and the heel, the distance between the opening and the upper is changed by the adjusting component, and the heel is fixed to the sole. At this time, the deformable part deforms. Since the deformable part conforms to the ankle and bends outward, it is conducive to the deformation of the deformable part and more conducive to adjusting the tightness of the heel.

[0021] In the second technical solution, since the opening is turned outward at the heel opening of the shoe, the surface of the opening must be curved. In order to better fit the opening, the shape of the base must match the shape of the opening, which helps to avoid the base and the opening being not firmly connected.

[0022] In the third technical solution, the arc-shaped protrusion is suitable for abutting the concave part of the ankle. Since the ankle has a curve, the dimension of the ankle is smaller than the dimension of the calf and the heel, that is, the ankle has a concave part. The design of the arc-shaped protrusion is conducive to better support of the ankle.

[0023] In the fourth technical solution, since the adjustment knob is located on the outside of the heel, it is likely to damage the adjustment component or injure the ankle if it is impacted. The side of the cushioning part near the adjustment knob abuts against the adjustment knob, and the middle of the cushioning part is hollowed out. The hollowed-out middle of the cushioning part is to make the cushioning part more easily deformable. When the adjustment knob is impacted, the cushioning part deforms to cushion the impact force on the adjustment component, which helps to avoid damage to the adjustment component and is more conducive to protecting the ankle from impact injury.

[0024] In the fifth technical solution, the connecting layer wraps around the outer surface of the support layer and connects to the upper. The sole buckle is fixed to the support layer and extends out through a hole to connect with the adjustment knob. This design aims to avoid the sole buckle being directly connected to the connecting layer. If the sole buckle were directly connected to the connecting layer, since the connecting layer is exposed on the outer surface of the heel, the connection would be unsightly, and the connection would be less secure due to the lower hardness of the connecting layer. The support layer is harder than the connecting layer, so the connection strength between the sole buckle and the support layer is greater than that between the sole buckle and the connecting layer.

[0025] In the sixth technical solution, the support layer is harder than the connecting layer and the cushioning layer. The support layer needs to be hard enough to support the ankle and will not be crushed by the downward pressure applied by the foot when wearing the shoe. The connecting layer is used to wrap the outer surface of the support layer and connect with the cushioning layer and the upper. The cushioning layer is used to wrap the inner surface of the support layer and conforms to the heel and ankle. The cushioning layer is used to adapt to the shape of the heel and ankle. When adjusting the tightness of the heel, the cushioning layer can always conform to the heel and ankle.

[0026] In the seventh technical solution, the bottom buckle and the support layer are connected by high-temperature melting, so that the support layer and the bottom buckle are integrated into one. Traditional adjustment components are usually sewn to the shoe body, which creates physical gaps. After long-term stress, the threads are prone to breakage or material delamination, leading to structural failure. Integrating the support layer and the bottom buckle into one helps to avoid material delamination in the heel of the shoe.

[0027] In the eighth technical solution, one end of the connector is wrapped around the adjustment knob, and the other end is fixed to the shoe upper. When the adjustment knob is turned, the length of the connector can be adjusted, so that the distance between the shoe upper and the heel can also be adjusted, which is beneficial to adjusting the tightness of the heel.

[0028] In the ninth technical solution, there are two connectors, which are symmetrically distributed on both sides of the shoe. When the adjustment knob is turned, the length of the two connectors is adjusted at the same time, and the two connectors can pull the support layer at the same time. This makes it easier to adjust the tightness of the shoe heel by distributing the force more evenly on the heel.

[0029] In the tenth technical solution, since the thickness of the buffer layer is greater than that of the support layer and the hardness of the buffer layer is less than that of the support layer, when the support layer is pulled and deformed close to the upper, the buffer layer can always wrap around the ankle, which is beneficial to improving the support of the heel.

[0042] Example

[0043] Figure 1 The shoe 1 in this embodiment is shown, as follows: Figure 1 As shown, shoe 1 includes upper 2 and heel 3, which are sewn together. Figure 2 The heel 3 in this embodiment is shown, as follows: Figure 2 As shown, the heel 3 includes a support layer 4, a connecting layer 5, a cushioning layer 6, an arc-shaped protrusion 7, and an adjustment component 8. The connecting layer 5 covers the outer surface of the support layer 4, and the cushioning layer 6 covers the inner surface of the support layer 4. In this embodiment, the connecting layer 5 and the cushioning layer 6 are sewn together, and the connecting layer 5 is bonded to the support layer 4, and the cushioning layer 6 is bonded to the support layer 4. In other embodiments, the connecting layer 5 and the support layer 4 can also be sewn together, and the cushioning layer 6 can also be sewn together. The support layer 4 is harder than the connecting layer 5 and the cushioning layer 6 because the support layer 4 needs sufficient rigidity to prevent it from being crushed by the downward pressure applied by the foot when wearing the shoe 1. The connecting layer 5 is used to cover the outer surface of the support layer 4 and connects to the cushioning layer 6 and the upper 2. The cushioning layer 6 is used to cover the inner surface of the support layer 4, and the cushioning layer 6 conforms to the heel and ankle, adapting to the shape of the heel and ankle. When adjusting the tightness of the heel 3, the cushioning layer 6 can always conform to the heel and ankle.

[0044] like Figure 2 As shown, the connecting layer 5 has a through hole 9 corresponding to the opening 10 of the support layer 4, and the connecting layer 5 is made of mesh fabric. The support layer 4 includes an opening 10, a deformation part 11, and a heel part 12 sequentially from the shoe opening 1 to the sole of the shoe 1. The opening 10 is turned outward at the opening of the heel 3 and conforms to the curve of the ankle. The shape of the heel part 12 conforms to the curve of the heel and is recessed inward at the sole of the shoe 1. The deformation part 11 wraps around the heel and curves outward. The cushioning layer 6 is thicker than the support layer 4. When the adjustment component 8 adjusts the tightness of the heel 3, the cushioning layer 6 always wraps around the ankle. This design is ergonomic and can provide a certain degree of support for the ankle, making it less prone to sprains. The arc-shaped protrusion 7 is set at the opening on the inner surface of the support layer 4. The arc-shaped protrusion 7 is fixedly connected to the inner surface of the support layer 4. The arc-shaped protrusion 7 is suitable for abutting against the concave part of the ankle. The design of the arc-shaped protrusion 7 is conducive to better support of the ankle.

[0045] like Figure 1 As shown, the adjustment assembly 8 includes an adjustment member 13 and a connecting member 14. The adjustment member 13 is fixed to the opening 10. One end of the connecting member 14 is connected to the adjustment member 13, and the other end is connected to the upper 2. The adjustment member 13 is adapted to change the length of the connecting member 14 to adjust the distance between the upper 2 and the heel 3. The deformable part 11 is adapted to deform to adapt to the adjustment assembly 8 adjusting the distance between the upper 2 and the heel 3. In this embodiment, there are two connecting members 14, which are symmetrically distributed on both sides of the shoe 1. One end of each connecting member 14 is connected to the same adjustment member 13, and the other end is connected to the upper 2. When the adjustment member 13 rotates, the lengths of the two connecting members 14 can be adjusted simultaneously, and the two connecting members 14 can pull the support layer 4 simultaneously.

[0046] Figure 2 The adjustment component 8 in this embodiment is shown, such as Figure 2 As shown, the adjusting component 13 includes an adjusting knob 15 and a bottom buckle 16. The adjusting knob 15 is adapted to rotate on the outer surface of the heel 3. The bottom buckle 16 is fixed to the opening 10 of the support layer 4. The bottom buckle 16 includes a base 17 and a connecting platform 18. The base 17 is shaped to fit the opening 10, and the connecting platform 18 is fixedly connected to the base 17. The adjusting knob 15 is rotatably connected to the connecting platform 18, as shown... Figure 1 and Figure 2 As shown, when the adjusting member 13 changes the length of the connecting member 14 to adjust the distance between the upper 2 and the heel 3, the deformable part 11 is adapted to deform to accommodate the adjusting assembly 8 adjusting the distance between the upper 2 and the heel 3. In this embodiment, the bottom buckle 16 is fixedly connected to the support layer 4 by high-temperature melting, the base 17 is integrally melted with the support layer 4, and the connecting platform 18 passes through the connecting layer 5 to the outer surface of the heel 3 through the through hole 9. Then, the connecting platform 18 is rotatably connected to the adjusting knob 15.

[0047] Figure 3The adjusting element 13 in this embodiment is shown, such as Figure 3 As shown, the bottom buckle 16 includes a base 17 and a connecting platform 18. The base 17 is shaped to fit the opening 10, the connecting platform 18 is fixedly connected to the base 17, and the adjusting knob 15 is rotatably connected to the connecting platform 18. Figure 3 As shown, the side of the connecting platform 18 near the adjusting knob 15 is horizontal, and the end away from the adjusting knob 15 is fixedly connected to the base 17. The connecting platform 18 is provided with a buffer part 19, which is fixedly connected to the base 17 and the connecting platform 18. The side of the buffer part 19 near the adjusting knob 15 is adapted to abut against the adjusting knob 15, and the other side is fixedly connected to the bottom surface. The buffer part 19 is hollow in the middle. In this embodiment, there is a gap between the adjusting knob 15 and the buffer part 19 under normal circumstances. When the adjusting knob 15 is impacted, the adjusting knob 15 will abut against the buffer part 19. At this time, the buffer part 19 deforms to buffer the impact force on the adjusting assembly 8. This design can help avoid ankle injury caused by the adjusting knob 15 being impacted, and also makes the adjusting knob 15 less easily damaged when it receives external impact.

[0048] This embodiment also discloses a method for manufacturing the heel 3 of a shoe, the steps of which include: mold assembly, high-temperature melting, pressure molding, cooling and demolding, and installation of adjustment knob 15.

[0049] Mold assembly: Stack the buffer layer 6, support layer 4, bottom buckle 16 and connecting layer 5 into the mold in sequence, and spray hot melt adhesive between the layers. When stacking the bottom buckle 16 and connecting layer 5, the connecting platform 18 of the bottom buckle 16 passes through the connecting layer 5 through the through hole 9.

[0050] High-temperature melting: The mold needs to be preheated to 240°C first, then the temperature is increased to 255°C so that the bottom buckle 16 and the support layer 4 reach a molten state. Finally, the temperature is raised to 260°C to completely fuse the support layer 4 and the bottom buckle 16 into one piece, and at this time the hot melt adhesive also reaches a molten state.

[0051] Pressure molding: When the initial pressure is 2MPa, the molten bottom buckle 16 and support layer 4, as well as the air bubbles in the hot melt adhesive, are expelled. Then, the pressure is continuously increased to 20MPa to completely compact the bottom buckle 16 and support layer 4.

[0052] Cooling: After the mold cools, the molten buffer layer 6, support layer 4, bottom buckle 16, and connecting layer 5 are demolded and removed. In this embodiment, the support layer 4, bottom buckle 16, and burrs generated by the hot melt adhesive are cut off after demolding, and the edges are stitched. In this embodiment, the stitch distance is 2.5mm / stitch, with double-line reinforcement. Other stitch distances can be used in other embodiments. Alternatively, in other embodiments, the edges can be reversed during high-temperature molding.

[0053] Install adjustment knob 15: Assemble and connect adjustment knob 15 to bottom buckle 16.

[0054] In this embodiment, the opening 10 is turned outward at the opening of the heel 3, so that when the foot applies downward pressure while wearing the shoe 1, the outward design of the opening will decompose part of the downward pressure and cause the opening to open outward, so that the user does not need to manually open the opening when wearing the shoe 1, which makes it easier for the user to wear the shoe 1.

[0055] In this embodiment, the heel portion 12 is shaped to fit the curve of the heel and is recessed inward at the bottom of the shoe 1. This design is ergonomic, which allows the heel 3 to better support the heel. Furthermore, the recessed heel portion 12 at the bottom of the shoe 1 and the outward folding of the opening portion 10 at the opening allow the deformable portion 11 of the support layer 4 to conform to the ankle and bend outward, which is beneficial for better ankle support.

[0056] In this embodiment, the adjusting member 13 is fixed to the opening 10. When the adjusting member 13 changes the length of the connecting member 14 to adjust the distance between the upper 2 and the heel 3, the distance between the opening 10 and the upper 2 is changed by the adjusting component 8, and the heel 12 is fixed to the bottom of the shoe 1. At this time, the deformable part 11 deforms. Since the deformable part 11 conforms to the ankle and bends outward, it is beneficial for the deformable part 11 to deform, which is more conducive to adjusting the tightness of the heel 3.

[0057] In this embodiment, since the opening 10 is turned outward at the opening of the heel 3, the surface of the opening 10 must be curved. In order to better fit the opening 10, the shape of the base 17 must match the shape of the opening 10, which helps to avoid the base 17 and the opening 10 being not firmly connected.

[0058] In this embodiment, the arc-shaped protrusion 7 is adapted to abut against the depression of the ankle. Since the ankle has a curve, the dimension of the ankle is smaller than the dimension of the calf and the heel, that is, the ankle has a depression. The design of the arc-shaped protrusion 7 is conducive to better support of the ankle.

[0059] In this embodiment, since the adjustment knob 15 is located outside the heel 3 of the shoe, once the adjustment knob 15 is impacted, it may damage the adjustment component 8 or cause injury to the ankle. The side of the buffer part 19 near the adjustment knob 15 abuts against the adjustment knob 15 and the buffer part 19 is hollow in the middle. The hollow in the middle of the buffer part 19 is to make the buffer part 19 more easily deformable. When the adjustment knob 15 is impacted, the buffer part 19 deforms to buffer the impact force on the adjustment component 8, which helps to avoid damage to the adjustment component 8 and is more conducive to protecting the ankle from being injured by the impact force.

[0060] In this embodiment, the connecting layer 5 wraps around the outer surface of the support layer 4 and connects to the shoe upper 2. The bottom buckle 16 is fixed to the support layer 4 and extends out of the through hole 9 to rotate and connect with the adjustment knob 15. This design aims to avoid the bottom buckle 16 being directly connected to the connecting layer 5. If the bottom buckle 16 is directly connected to the connecting layer 5, since the connecting layer 5 is exposed on the outer surface of the heel 3, this connection is not aesthetically pleasing, and the connection between the bottom buckle 16 and the connecting layer 5 is not tight due to the relatively low hardness of the connecting layer 5. The support layer 4 has a higher hardness than the connecting layer 5, so the connection strength between the bottom buckle 16 and the support layer 4 is greater than the connection strength between the bottom buckle 16 and the connecting layer 5.

[0061] In this embodiment, the support layer 4 is harder than the connecting layer 5 and the cushioning layer 6. The support layer 4 needs to be hard enough to support the ankle and not be crushed by the downward pressure applied by the foot when wearing the shoe 1. The connecting layer 5 is used to wrap the outer surface of the support layer 4 and connect to the cushioning layer 6 and the upper 2. The cushioning layer 6 is used to wrap the inner surface of the support layer 4 and conforms to the heel and ankle. The cushioning layer 6 is used to adapt to the shape of the heel and ankle. When adjusting the tightness of the heel 3, the cushioning layer 6 can always conform to the heel and ankle.

[0062] In this embodiment, the bottom buckle 16 is connected to the support layer 4 by high-temperature melting, so that the support layer 4 and the bottom buckle 16 are fused into one. Traditional adjustment components are usually sewn to the shoe body, which creates physical gaps. After long-term stress, the thread ends are prone to breakage or material delamination, leading to structural failure. Fusing the support layer 4 and the bottom buckle 16 into one helps to avoid material delamination in the heel 3 of the shoe.

[0063] In this embodiment, one end of the connector 14 is wrapped around the adjustment knob 15, and the other end is fixed to the upper 2. When the adjustment knob 15 is rotated, the length of the connector 14 can be adjusted, so that the distance between the upper 2 and the heel 3 is also adjusted, which is beneficial to adjusting the tightness of the heel 3.

[0064] In this embodiment, there are two connectors 14. The connectors 14 are symmetrically distributed on both sides of the shoe 1. When the adjustment knob 15 is turned, the length of the two connectors 14 is adjusted at the same time. The two connectors 14 can pull the support layer 4 at the same time, which is beneficial to make the force on the heel 3 more even when adjusting the tightness of the heel 3, and is more conducive to adjusting the tightness of the heel 3.

[0065] In this embodiment, since the thickness of the buffer layer 6 is greater than that of the support layer 4 and the hardness of the buffer layer 6 is less than that of the support layer 4, when the support layer 4 is pulled and deformed close to the upper 2, the buffer layer 6 can always wrap around the ankle, which is beneficial to improving the support of the heel 3.

[0066] In this embodiment, hot melt adhesive is sprayed between layers because when the temperature rises, the hot melt adhesive will reach a molten state, and at this temperature the viscosity of the hot melt adhesive will not fail, which helps to avoid delamination caused by the failure of other adhesives.

[0067] In this embodiment, when the temperature rises, bubbles will be generated in the hot melt adhesive, the bottom buckle 16 and the support layer 4, or bubbles will be generated in the gaps between them. Therefore, it is necessary to use an initial pressure of 2MPa to expel the bubbles in the molten bottom buckle 16 and the support layer 4 to avoid weak adhesion.

[0068] In this embodiment, since the bottom buckle 16 and the support layer 4 are melted together by high temperature melting, the molten material may overflow to the edge and form burrs. For aesthetics and comfort, the burrs of the support layer 4, bottom buckle 16 and hot melt adhesive after demolding need to be cut off, which helps to improve aesthetics and comfort.

[0069] 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.
