Description

Technical Field

[0001] This utility model relates to the field of shoe technology, specifically to a shoe that automatically returns to its original position upon landing. Background Technology

[0002] When shoes are casually taken off and placed on the ground, or when they fall from the feet while still in use, they are prone to tipping over on the ground due to uneven force after contact with the ground. In this case, the shoe surface will touch the ground, causing the shoe surface to get dirty. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a shoe that automatically returns to its original position upon landing, which can reduce the chance of the shoe tipping over after falling off.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A shoe that automatically returns to its original position upon landing, comprising a sole and a shoe body, and further comprising a plurality of elastic guide members distributed in pairs on the left and right sides of the shoe; the elastic guide members extend in the vertical direction, with their bottom ends fixed to the side walls of the sole and / or the shoe body, and their top ends not lower than the upper surface of the corresponding part of the shoe body in the left and right direction.

[0009] Technical Solution 5 based on Technical Solution 1: The elastic guide is at least distributed in the forefoot and heel of the shoe.

[0010] Technical Solution Six based on Technical Solution One: The bottom edges of the left and right sides of the sole are at least in the arch position and are outwardly convex arcs.

[0011] Technical solution seven based on technical solution one: also includes a cushioning component; the bottom surface of the sole is recessed and provided with a receiving groove extending in the front-to-back direction, the openings of the receiving grooves extend towards each other to form an inwardly recessed limiting groove on the groove wall of the receiving groove; the cushioning component is provided with a support piece and a cushioning piece in sequence with gaps from top to bottom, the left and right sides of the support piece and the cushioning piece are connected to two snap-fit ​​parts provided on the left and right sides of the cushioning component, the two snap-fit ​​parts are supported and snapped into the limiting groove, and the support piece and the cushioning piece of the cushioning component are curved in a shape that protrudes downwards from the bottom surface of the sole.

[0012] Technical solution eight, based on technical solution seven, also includes an elastic sheet; the snap-fit ​​portion extends toward the middle position in the left-right direction of the shoe and is provided with a snap-fit ​​flange, the left and right sides of the elastic sheet are snapped below the snap-fit ​​flange and are limited and fixed above the support sheet by the snap-fit ​​portion and the snap-fit ​​flange; the elastic sheet is adapted to change from a downward convex bending shape to an upward convex bending shape when the buffer is deformed upward by force and when force is applied to the elastic sheet.

[0013] Technical solution nine based on technical solution eight further includes a reset member, which is slidably installed at the bottom of the receiving groove in the front-back direction and located above the elastic sheet, and is adapted to abut against the elastic sheet in the upwardly convex curved shape and apply downward force to the elastic sheet to restore it to the downwardly convex curved shape during the process of sliding from the first position to the second position.

[0014] Technical solution ten based on technical solution nine: The reset member is provided with an operating part, and the operating part is exposed in the receiving groove.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] Technical solution one provides a shoe that automatically returns to its original position upon landing. The shoe has several elastic guide members arranged in pairs on its left and right sides. These elastic guide members extend vertically and their bottom ends are fixed to the sidewalls of the shoe, while their top ends are not lower than the upper surface of the shoe at the corresponding position. With this design, if the shoe falls and tilts, the elastic guide members will first contact the ground. Due to the impact force of the fall, this force will react on the elastic guide members, causing them to deform. The elastic guide members then tend to return to their original shape. Combined with the relatively heavy sole, this changes the shoe's center of gravity, guiding the shoe to flip downwards, thus achieving a certain degree of automatic return to its original position after landing.

[0017] In technical solution two, the elastic guide bends or extends obliquely from bottom to top toward the middle position of the shoe in the left-right direction. This shape can prevent the elastic guide from extending too far beyond the shoe's range, making the overall appearance of the shoe more harmonious, while ensuring that the guiding function of the elastic guide for shoe rotation is not affected.

[0018] In technical solution three, guide ridges are provided on the elastic guide component. When the elastic guide component touches the ground, the guide ridges reduce the contact area between the elastic guide component and the ground, allowing the reaction force on the elastic guide component to act more concentrated on itself, improving the rebound effect of the elastic guide component and accelerating the shoe's rotation process. At the same time, the guide ridges also improve the overall structural strength of the elastic guide component and enhance its elastic recovery capability.

[0019] In technical solution four, the elastic guide component includes an inner core and an outer shell. The inner core, with a higher elastic modulus, provides sufficient elastic support and restoring force, ensuring that the guide component can quickly return to its original shape after being subjected to force, and is not prone to fatigue after repeated use. The outer shell provides good tactile feel and wear resistance, and different materials can be selected as needed to adjust the softness and hardness of the guide strip to adapt to different ground environments, while protecting the inner core from wear and corrosion.

[0020] In technical solution five, elastic guide components are distributed in both the forefoot and heel of the shoe, which can ensure that the shoe can effectively return to its correct position under different falling postures. Whether the shoe lands front-first, back-first, or side-first, the guide component in the forefoot or heel of at least one side can play a role, improving the success rate of the shoe's return to its correct position.

[0021] In technical solution six, the bottom edges of the left and right sides of the sole are curved outwards at least at the arch position. These curved bottom edges create a rolling fulcrum when the shoe lands on its side, making it easier for the shoe to roll along the curve and eventually flip to a sole-down position. The curved bottom edges work in conjunction with the elastic guide to further enhance the shoe's self-correcting ability.

[0022] In technical solution seven, the sole surface is recessed with a receiving groove extending in the front-to-back direction, and a limiting groove is formed within the opening of the receiving groove. The cushioning component consists of a support plate and a cushioning plate, which are engaged in the limiting groove via a snap-fit ​​part, causing the support plate and the cushioning plate of the cushioning component to protrude downwards towards the sole. When the shoe lands, if the sole hits the ground directly, without a cushioning component, the shoe will bounce and tip over. With a cushioning component, the cushioning plate first contacts the ground and absorbs part of the impact force through deformation. Then, the cushioning plate contacts the support plate, which also absorbs part of the impact force. The gap between the cushioning plate and the support plate improves the overall cushioning effect of the cushioning component. Under the action of the cushioning component, when the sole hits the ground directly, most of the impact force on the shoe is absorbed by the cushioning component, thus preventing the shoe from tipping over due to bounce.

[0023] In technical solution eight, an elastic sheet is incorporated, which is fixed above the support sheet via a snap-fit ​​structure. When the buffer is subjected to force, the elastic sheet can deform upwards, and when force is applied to the elastic sheet, it can change from a downward-convex bending shape to an upward-convex bending shape. The addition of the elastic sheet enhances the elasticity of the buffer, enabling it to better absorb impact energy and provide a softer landing experience.

[0024] In technical solution nine, a reset component is slidably installed at the bottom of the receiving groove, positioned above the elastic sheet. During sliding, the reset component abuts against the elastic sheet in its upward-protruding state and applies a downward force, restoring it to its downward-protruding bent shape. After the elastic sheet deforms under force, the reset component actively restores it to its initial state, preparing it for the next buffering and straightening action.

[0025] In technical solution ten, the reset component is provided with an operating part, which protrudes from the receiving groove. The operating part allows the user to manually control the sliding of the reset component. Attached Figure Description

[0044] Example

[0045] This utility model relates to a shoe that automatically returns to its original position upon landing, as described in the following embodiment. Figure 1 The shoe includes a sole 1 and a shoe body 101, as well as a fixing strap 2, several elastic guides 3, a cushioning member 4, an elastic sheet 403, and a reset member 7.

[0046] The sole 1 of the shoe can be made of conventional materials such as rubber, nylon, or EVA foam, while the upper 101 can be made of materials such as leather or mesh. For details, refer to... Figure 1The shoe body 101 includes an upper 102, a tongue 103, a rear protective plate, and a front protective plate. The upper 102 is primarily made of woven mesh material, providing excellent breathability. The tongue 103 is a flexible sheet structure located at the front of the shoe, covering the instep and lace area. Both the rear and front protective plates are made of rigid leather. The rear protective plate is located at the heel of the shoe body 101 and wraps around the heel in a semi-circular shape, providing circumferential support for the user's heel. The front protective plate is located at the forefoot of the shoe body 101 and covers the toe box, providing protection for the user's toes and preventing them from hitting hard objects. A fastening strap 2 is located at the tongue 103 of the shoe body 101, with one end fixed to one side of the shoe body 101 in the left-right direction, and the other end extending left-right and crossing the tongue 103 to connect with a detachable connecting component such as a Velcro strap or buckle on the other side of the shoe body 101 in the left-right direction. Furthermore, refer to... Figure 4 Furthermore, on the forefoot area of ​​the sole 1, anti-slip horizontal ridges can be recessed. These ridges extend from one edge of the sole 1 in the left-right direction to the other edge, and multiple ridges are provided in the front-back direction, thereby improving the anti-slip performance of the sole 1. Additionally, the anti-slip ridges can be designed in a wavy pattern to further enhance the anti-slip performance.

[0047] Reference Figure 1 The bottom edges of the left and right sides of the sole 1 are curved outwards at least at the arch position. Specifically, curved portions 5 are formed on the bottom edges of the left and right sides of the sole 1. The curved portions 5 extend in the front-rear direction of the sole 1, mainly located at the arch position of the sole 1, and extend forward to the forefoot and then to the heel. In the curved portions 5, the bottom edge of the sole 1 is set to be curved outwards. Here, "curved" means that when viewed from a cross-section perpendicular to the front-rear direction of the sole 1, the bottom edge of the sole 1 smoothly transitions from the bottom surface of the sole 1 to the sidewall of the sole 1 in a curved shape, and the curvature is outwards. The curved bottom edges of the left and right sides of the sole 1 are curved outwards at least at the arch position. When the shoe is tilted to the side, the curved bottom edges of the sole 1 can form a rolling fulcrum, making it easier for the shoe to roll along the curve and eventually flip to a position with the sole 1 facing down. The curved bottom edge works in conjunction with the elastic guide 3 to further enhance the shoe's self-alignment ability.

[0048] Reference Figure 1 and Figure 2The elastic guide members 3 are distributed in pairs on the left and right sides of the shoe. Each elastic guide member 3 extends vertically, with its bottom end fixed to the side wall of the sole 1 and / or the upper 101, and its top end not lower than the upper surface of the corresponding portion of the upper 101 in the left-right direction. Furthermore, the elastic guide members bend or extend obliquely from bottom to top towards the middle position of the shoe in the left-right direction. Additionally, each elastic guide member 3 has a protruding guide ridge 303 on its outward-facing side surface relative to the shoe, extending along the front-back direction. Each elastic guide member 3 includes an inner core 302 and an outer shell 301; the inner core 302 is made of elastic metal or plastic material, and the outer shell 301 encloses the inner core 302 and is made of elastic rubber, silicone, or plastic.

[0049] Specifically, the elastic guides 3 are distributed at least in the forefoot and heel of the shoe. In this embodiment, a pair of elastic guides 3 are provided in the forefoot and a pair of elastic guides 3 are provided in the heel. The bottom end of the elastic guide 3 located in the forefoot is fixed to the side wall of the sole 1, and the bottom end of the elastic guide 3 located in the heel is fixed to the side wall of the shoe body 101, specifically fixed to the rear protective plate. The elastic guides 3 are distributed in both the forefoot and heel of the shoe, which can ensure that the shoe can effectively return to its correct position under different falling postures. Whether the shoe lands front-first, rear-first, or side-first, at least one guide in the forefoot or heel can play a role, improving the success rate of the shoe's return to its correct position.

[0050] All elastic guide members 3 extend vertically, with their tops higher than the upper surface of the corresponding shoe body 101. For example, the elastic guide member 3 located at the forefoot corresponds to the forefoot portion of the shoe body 101, and its top is higher than that portion of the shoe body 101; similarly, the elastic guide member 3 located at the heel corresponds to the heel portion of the shoe body 101, and its top is higher than that portion of the shoe body 101, i.e., higher than the edge of the shoe opening. Also, refer to... Figure 2 In this embodiment, the elastic guide 3 is configured to bend towards the middle position in the left-right direction of the shoe. That is, starting from the bottom end of the elastic guide 3, the elastic guide 3 gradually extends in a curved shape towards the middle position in the left-right direction of the shoe to its top end. The elastic guide 3 bends or extends obliquely from bottom to top towards the middle position in the left-right direction of the shoe. This shape can prevent the elastic guide 3 from extending too far beyond the range of the shoe, making the overall appearance of the shoe more harmonious, while ensuring that the guiding function of the elastic guide 3 for the shoe's rotation is not affected.

[0051] Reference Figure 3The elastic guide 3 is composed of an elastic inner core 302 and an elastic outer shell 301. The outer shell 301 encloses the inner core 302, forming a core-shell structure. The inner core 302 can be made of metal or plastic, while the outer shell 301 can be made of rubber, silicone, or plastic. It should be noted that the elastic modulus of the inner core 302 is higher than that of the outer shell 301. When the elastic guide 3 is fixed to a shoe, the bottom end of the inner core 302 is fixed to the sole 1 or upper 101 of the shoe. The outer shell 301 is detachably fitted onto the inner core 302 and can be replaced as needed. The method of fixing the inner core 302 to the sole 1 or upper 101 of the shoe is adapted to the material of the inner core 302. Under normal circumstances, the inner core 302 can be fixed by welding, including ultrasonic welding. The elastic guide 3 includes an inner core 302 and an outer shell 301. The inner core 302, with its higher elastic modulus, provides sufficient elastic support and restoring force, ensuring that the guide can quickly return to its original shape after being subjected to force, and is not prone to fatigue after repeated use. The outer shell 301 provides a good tactile feel and wear resistance, and different materials can be selected as needed to adjust the softness and hardness of the guide strip to adapt to different ground environments, while protecting the inner core 302 from wear and corrosion.

[0052] Continue to refer to Figure 3 The elastic guide 3 is provided with a guide ridge 303, which is located on the outward side of the elastic guide 3 and extends along its length. On the side of the elastic guide 3 facing the shoe body 101, it has a relatively large contact surface, which can ensure sufficient contact between the elastic member and the shoe body 101. The guide ridge 303 has a structure with a gradually narrowing width at the free end. When the elastic guide 3 touches the ground, the guide ridge 303 reduces the contact area between the elastic guide 3 and the ground, so that the reaction force on the elastic guide 3 can be more concentrated on itself, improving the rebound effect of the elastic guide 3 and accelerating the shoe's rotation process. At the same time, the setting of the guide ridge 303 can also improve the overall structural strength of the elastic guide 3 and improve its elastic recovery ability.

[0053] Reference Figure 4 and Figure 6The bottom surface of the sole 1 is recessed and has a receiving groove 8 extending in the front-to-back direction. The openings of the receiving groove 8 extend towards each other to form an inwardly recessed limiting groove 801 on the groove wall of the receiving groove 8. The cushioning member 4 is provided with a support piece 401 and a cushioning piece 402 in sequence from top to bottom with a gap. The left and right edges of the support piece 401 and the cushioning piece 402 are connected to two snap-fit ​​parts 405 provided on the left and right sides of the cushioning member 4. The two snap-fit ​​parts 405 are supported and snapped into the limiting groove 801, and the support piece 401 and the cushioning piece 402 of the cushioning member 4 are curved and protrude downward toward the bottom surface of the sole 1.

[0054] Specifically, refer to Figure 4 and Figure 6 The receiving groove 8 is located at the heel and arch of the sole 1 and extends in the front-to-back direction. Limiting grooves 801 are recessed on both sides of the receiving groove 8, also extending in the front-to-back direction. Due to the presence of the limiting grooves 801, the left and right edges of the opening of the receiving groove 8 tend to extend towards each other; that is, the distance between the bottoms of the two limiting grooves 801 is greater than the distance between the two edges of the opening of the receiving groove 8. Simultaneously, a sliding ridge 802 extending in the front-to-back direction and protruding from the bottom (top) of the receiving groove 8 is provided, extending to the front end of the receiving groove 8.

[0055] The buffer 4 is made of elastic plastic, and the buffer sheet 402 can be wrapped with soft material on its outside to increase the buffering and energy absorption effect of the buffer 4. A gap is formed between the buffer sheet 402 and the support sheet 401, so that the buffer sheet 402 can bend more than the support sheet 401. The left and right edges of the buffer plate 402 and the support plate 401 are connected to the two snap-fit ​​parts 405 of the buffer member 4, thereby combining the buffer plate 402 and the support plate 401 into a buffer member 4. The buffer member 4 is roughly flat in the initial state. At this time, the distance between its left and right edges is greater than the distance between the bottom of the two limiting grooves 801. Then, the left and right snap-fit ​​parts 405 of the buffer member 4 can be inserted from the opening of the receiving groove 8 into the limiting groove 801. Since the bottom distance of the limiting groove 801 is short, the buffer member 4 can no longer be flat. Instead, it will be blocked by the limiting groove 801 and maintain a downward convex bending state. The buffer member 4 will protrude from the bottom surface of the shoe sole 1, thus contacting the ground earlier than the shoe sole 1. When the shoe lands, if the sole 1 hits the ground directly, without the cushioning element 4, the shoe will bounce and tip over. With the cushioning element 4 in place, the cushioning plate 402 first contacts the ground and absorbs some of the impact force through deformation. Then, the cushioning plate 402 contacts the support plate 401, which also absorbs some of the impact force. The gap between the cushioning plate 402 and the support plate 401 improves the overall cushioning effect of the cushioning element 4. With the cushioning element 4 in place, when the sole 1 hits the ground directly, most of the impact force is absorbed by the cushioning element 4, thus preventing the shoe from bouncing and tipping over.

[0056] In addition, refer to Figure 6 The snap-fit ​​portion 405 extends toward the middle position in the left-right direction of the shoe and has a snap-fit ​​flange. The left and right sides of the elastic piece 403 are snapped below the snap-fit ​​flange and are limited and fixed above the support piece 401 by the snap-fit ​​portion 405 and the snap-fit ​​flange. The elastic piece 403 is adapted to change from a downward convex bending shape to an upward convex bending shape when the buffer 4 is subjected to force and deforms upward, and when force is applied to the elastic piece 403.

[0057] Specifically, the elastic sheet 403 can be made of metal to provide better fatigue resistance. A snap-fit ​​flange is provided on the inward-facing surface of the snap-fit ​​portion 405 of the buffer member 4. The snap-fit ​​flange extends along the front-rear direction of the buffer member 4. The left and right sides of the elastic sheet 403 can snap into the underside of the snap-fit ​​flange. When the buffer member 4 is located within the receiving groove 8, the snap-fit ​​portion 405 of the buffer member 4 is inclined, while the extension direction of the snap-fit ​​flange is approximately horizontal. Therefore, the snap-fit ​​flange and the portion of the snap-fit ​​portion 405 below it form a space for the elastic sheet 403 to snap into. The elastic sheet 403 can snap into this position and will not come off the buffer member 4. When the elastic sheet 403 is snapped into this position, the left and right sides of the elastic sheet 403 are subjected to force, causing the elastic sheet 403 to also bulge downwards and bend. The elastic sheet 403 is fixed above the support piece 401 by the snap-fit ​​structure. The elastic sheet 403 can deform upward when the buffer 4 is subjected to force, and when force is applied to the elastic sheet 403, it can change from a downward convex bending shape to an upward convex bending shape. The addition of the elastic sheet 403 enhances the elasticity of the buffer 4, which can better absorb impact energy and provide a softer landing experience.

[0058] Reference Figure 4 , Figure 5 and Figure 6 The reset member 7 is slidably mounted on the bottom of the receiving groove 8 in the front-rear direction and located above the elastic sheet 403. It is adapted to abut against the upwardly convex, bent elastic sheet 403 and apply downward force to the elastic sheet 403 to restore it to its downwardly convex bent shape during the sliding process from the first position to the second position. Furthermore, the reset member 7 is provided with an operating part 702, which protrudes from the receiving groove 8.

[0059] The reset member 7 is further provided with a reset part 701, which can be used to abut against the elastic piece 403. The reset member 7 and the sliding protrusion 802 provided on the bottom of the receiving groove 8 are slidably engaged by a snap-fit ​​mechanism. The reset member 7 can move between a first position and a second position in the front-back direction. When it is in the first position, the operating part 702 is exposed from the receiving groove 8. This exposure means that the operating part 702 can be operated, and it can still be within the receiving groove 8. At this time, the reset part 701 does not abut against the elastic piece 403, regardless of whether the elastic piece 403 protrudes downward or upward. When the reset member 7 is in the second position, the operating part 702 can still be exposed from the receiving groove 8. At this time, the reset part 701 can abut against the elastic piece 403 or not. However, during the process of the reset member 7 moving from the first position to the second position, the reset part 701 will inevitably have an abutment relationship with the elastic piece 403 in the upward protruding state. The reset part 701 of the reset member 7 can be specifically configured as a downwardly protruding structure, and its rearward end can be configured with an inclined guide structure so as to contact the elastic sheet 403 and apply force to the elastic sheet 403. During the sliding process, the reset member 7 can abut against the elastic sheet 403 in the upwardly protruding state and apply a downward force to restore it to the downwardly protruding bent shape. After the elastic sheet 403 is deformed by force, the reset member 7 can actively restore the elastic sheet 403 to the initial state, preparing for the next buffering and straightening action. The operation part 702 allows the user to manually control the sliding of the reset member 7.

[0060] This utility model embodiment relates to a shoe that automatically returns to its original position upon landing. The shoe has a plurality of elastic guide members 3 arranged in pairs on its left and right sides. The elastic guide members 3 extend vertically and their bottom ends are fixed to the sidewall of the shoe, while their top ends are not lower than the upper surface of the shoe body 101 at the corresponding position. With this configuration, if the shoe falls and tilts, the elastic guide members 3 will first contact the ground. Due to the impact force of the fall, this force will react on the elastic guide members 3, causing them to deform. The elastic guide members 3 then tend to recover their deformed shape. Combined with the heavier sole 1, this changes the shoe's center of gravity, guiding the shoe to flip downwards towards the sole 1, thus achieving a certain degree of automatic return to its original position after landing.

[0061] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
