[0002] In order to allow users to put on shoes and ensure that the shoes do not fall off their feet, shoes are generally provided with shoelaces or similar fasteners that can be fastened. When putting on shoes, users need to loosen the fasteners first and then fasten the fasteners after their feet enter the shoes. The overall process is rather cumbersome, and some shoes have shoe openings that are not adjusted to be loose enough, and shoes need to be put on easily with the help of a shoe horn or hands. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and provide a pair of shoes that are easy to put on and take off, so that users can put on and take off the shoes conveniently.

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

[0005] Technical solution 1: A shoe that is easy to put on and take off, comprising: a body, which includes a sole and an upper connected to the sole; the upper includes a forefoot surface and a heel surface, the rear edge of the forefoot surface extends obliquely from top to bottom and from front to back to the heel of the sole, and the front edge of the heel surface extends from top to bottom and from back to front to the arch of the sole or the rear side of the arch of the sole; the forefoot surface and the heel surface overlap from the arch to the heel of the sole, and in the overlapping part of the two, the heel surface is located at the The inner side of the forefoot surface; and an elastic heel, which is fixedly connected to the body and includes a deformation portion located at the rear end of the body; the deformation portion includes a sliding section and a deformation section from top to bottom, the inner side surface of the sliding section extends obliquely from top to bottom and from back to front, the inner surface of the deformation section is adapted to the shape of the heel of the foot, and the deformation section is suitable for recovering under its own elasticity after being compressed; the lower end of the deformation portion is connected to the sole, and the deformation portion is connected to the outer side surface of the heel surface at least in the deformation section.

[0006] Technical solution 2 based on technical solution 1: the outer surface of the deformation part is provided with a plurality of ridges spaced from top to bottom in the deformation section; the height of the ridges starts from the position corresponding to the midline of the shoe and gradually decreases toward both sides of the shoe.

[0007] Technical solution three based on technical solution two: a plurality of grooves are arranged at intervals from top to bottom on the inner surface of the deformation portion in the deformation section, and the grooves are in the shape of long strips extending along the two sides of the shoe.

[0008] Technical solution 4 based on technical solution 3: each of the convex edges on the deformation portion corresponds to the position of one of the grooves in the up and down directions.

[0009] Technical solution five based on technical solution four: the elastic heel includes an upper wing portion; the upper wing portion is formed by two side edges at the upper side of the deformation portion extending forward and laterally, and is connected to the outer surface of the heel surface.

[0010] Technical solution six based on technical solution five: the elastic heel includes a lower wing portion, which is formed by two side edges at the lower side of the deformation portion extending forward and laterally, and is fixedly connected to the sole.

[0011] Technical Solution 7 based on Technical Solution 5: The position of the uppermost ridge on the deformation portion in the up and down direction corresponds to the upper wing portion, and the length of the ridge on the deformation portion in the direction of both sides of the shoe tends to first decrease and then increase from top to bottom.

[0012] Technical solution eight based on technical solution seven: the edges of the deformation portion on both sides of the shoe are smoothly transitioned and connected with the upper wing portion and the lower wing portion.

[0013] Technical solution nine based on technical solution eight: a connecting portion is provided at the bottom of the elastic heel, and the connecting portion is embedded in the sole to fix the elastic heel to the sole.

[0014] In addition, the present invention also provides technical solution ten: the elastic heel is made of TPU or TPEE material.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical solution 1 provides a shoe that is easy to put on and take off, the shoe comprises a body and an elastic heel, the body comprises a sole and an upper, the upper comprises a forefoot surface and a heel surface separated from each other, the forefoot surface and the heel surface have an overlapping portion, and the heel surface is located on the inner side of the forefoot surface at the overlapping position; at the same time, the elastic heel is arranged at the rear end of the body, and comprises a deformation part located at the rear end of the body and connected to the sole at the lower end, the deformation part comprises a sliding section and a deformation section from top to bottom, the deformation section is elastic, and when compressed When the pressure is removed or the pressure decreases to a critical value, the deformed section can restore the deformation. When the user wears the shoe, the user can first extend the front section of the foot into the shoe cavity from the shoe opening formed by the forefoot surface and the heel surface. Due to the obstruction of the instep position of the forefoot surface, the user's foot cannot completely enter the shoe cavity. At this time, the user's heel will contact the heel surface and first contact the sliding section of the elastic heel. Since the inner surface of the sliding section extends obliquely from top to bottom and from back to front, a backward shape is formed. Therefore, a larger part of the user's heel will fit into the sliding section, and the heel can be inserted into the shoe cavity more smoothly; then the user's heel applies force to the elastic heel, so that the deformation section is compressed and deformed, and the elastic heel is pressed down as a whole. At the same time, since the forefoot surface and the heel surface are separated structures, the heel surface on both sides of the shoe will deform with the downward pressure of the elastic heel, and this deformation will not be constrained by the forefoot surface, and the deformation degree of the heel surface is greater and the deformation range is controllable. Afterwards, the front part of the user's foot can continue to extend forward into the shoe cavity until the user's heel also extends into the shoe cavity. At this time, the pressure of the user's heel on the deformation part of the elastic heel is reduced. Under the action of the deformation part, the elastic heel restores its original shape and drives the heel surface to restore deformation, thereby completing the shoe-wearing action. At this time, the deformation part fits the heel of the foot and can restrain the foot to prevent the shoe from falling off; when taking off the shoe, fix the heel of the shoe and lift the foot from the shoe cavity.

[0017] In the second technical solution, a number of ridges are arranged at intervals along the up-and-down directions on the outer surface of the deformation part, and the height of the ridges starts from the position corresponding to the midline of the shoe and gradually decreases toward the two sides of the shoe; the arrangement of the ridges changes the deformation section of the deformation part from the structure with uniform thickness in the conventional design, and when the deformation part is compressed and deformed, the ridges can pull the two sides of the deformation part so that the deformation part is only bent in the front-to-back direction without deflection, so its performance in recovering deformation is better, and at the same time, the structure is less prone to material fatigue and can have a longer service life.

[0018] In technical solution three, a number of grooves are arranged at intervals along the up and down directions on the inner surface of the deformation part, and the grooves are in the shape of long strips extending along the two sides of the shoe. When the elastic heel is deformed, the presence of the grooves can make the elastic heel deform in a preset manner, thereby avoiding the elastic heel from piling up when it is compressed. The structure is less prone to material fatigue and can have a longer service life. In addition, by providing the grooves, the deformation part can also have better deformation ability, avoiding the elastic heel from breaking due to frequent compression.

[0019] In technical solution four, each ridge on the deformation part corresponds to the position of a groove in the up and down direction, further constraining the deformation mode of the elastic heel, improving the deformation recovery ability of the elastic heel, reducing the material fatigue of the elastic heel, and increasing the service life of the elastic heel.

[0020] In technical solution five, the elastic heel includes an upper wing portion, which is formed by the two side edges of the upper side of the deformation portion extending forward and laterally, and is connected to the outer surface of the heel surface; the upper wing portion can improve the wrapping of the elastic heel on the heel surface, thereby improving the wrapping performance of the shoe on the heel of the foot. At the same time, the upper wing portion can also increase the contact area between the elastic heel and the user's foot when the user wears the shoe, and the user can easily press down to deform the elastic heel.

[0021] In technical solution six, the elastic heel includes a lower wing portion, which is formed by the two side edges of the lower side of the deformation portion extending forward and laterally, and is fixedly connected to the sole; through the lower wing portion, the overall support performance of the elastic heel can be improved, and the deformation of the deformation portion is not only generated relative to the sole, but also relative to the lower wing portion. The elastic heel formed by the lower wing portion and the deformation portion has a higher deformation ability as a whole. After the user's foot enters the shoe cavity to a certain extent, the elastic heel can restore the deformation by itself, thereby improving the efficiency and comfort of wearing shoes.

[0022] In Technical Solution 7, the position of the uppermost ridge on the deformation part in the up-down direction corresponds to the upper wing part, and the length of the ridge on the deformation part in the direction of both sides of the shoe decreases first and then increases from top to bottom; the shape and size of the ridge are adapted to the size of the elastic heel as a whole in the direction of both sides of the shoe, which can ensure that the ridge has a maximized auxiliary effect at each position of the deformation part and is more harmonious in appearance.

[0023] In technical solution eight, the edges of the deformation part on both sides of the shoe are smoothly transitioned to the upper wing part and the lower wing part to avoid stress concentration caused by abrupt turns, which can effectively improve the overall deformation performance of the elastic heel.

[0024] In technical solution nine, a connecting portion is provided at the bottom of the elastic heel, and the connecting portion is embedded in the sole to fix the elastic heel to the sole. The connecting portion can improve the firmness of the connection between the elastic heel and the sole and provide a basis for the deformation of the elastic heel.

[0025] In technical solution ten, the elastic heel is made of TPU or TPEE material. TPU or TPEE material has good elasticity and wear resistance, and is very suitable for parts such as elastic heels that require frequent deformation and recovery. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0038] The embodiment of the present invention relates to a pair of shoes that are easy to put on and take off. Figure 1 The shoe comprises a body 1 and an elastic heel 6.

[0039] Reference Figure 1 The main body 1 includes a sole 2 and an upper 3 connected to the sole 2; the upper 3 includes a forefoot surface 4 and a heel surface 5, the rear edge of the forefoot surface 4 extends obliquely from top to bottom and from front to back to the heel of the sole 2, and the front edge of the heel surface 5 extends from top to bottom and from back to front to the arch of the sole 2 or the rear side of the arch of the sole 2; the forefoot surface 4 and the heel surface 5 overlap from the arch to the heel of the sole 2, and in the overlapping part, the heel surface 5 is located on the inner side of the forefoot surface 4.

[0040] Specifically, the sole 2 of the main body 1 is of a conventional structure and can be formed by a composite outsole and a midsole. The outsole can be made of a relatively wear-resistant material such as nylon and rubber, and the midsole can be made of a polymer foam material such as EVA to provide better rebound and shock-absorbing properties.

[0041] The upper 3 of the body 1 is fixed on the sole 2 by sewing, bonding, etc. The material of the upper 3 can be mesh, foam, etc. Figure 1 The upper 3 includes a forefoot surface 4 located at the front position of the shoe, and a heel surface 5 located at the heel position of the shoe. The forefoot surface 4 can be sewn or bonded to the sole 2, and the heel surface 5 can also be sewn or bonded to the sole 2, and the forefoot surface 4 is separated from the heel surface 5. Specifically, the forefoot surface 4 can be compared to the structure of a conventional slipper. After being compounded on the sole 2, it forms a shoe cavity without a heel structure, and its approximate range corresponds to the position from the toes to the instep of the foot, that is, the position for configuring the tongue; the top of the rear edge of the forefoot surface 4 corresponds to the instep position of the user's foot, and the bottom of the rear edge extends to the position corresponding to the heel position of the user's foot. In this structure, the rear edge of the forefoot surface 4 extends obliquely from top to bottom and from front to back. The heel surface 5 in this embodiment is similar to the heel part of a conventional shoe, except that the heel surface 5 is not connected to the forefoot surface 4, and the heel surface 5 is only connected to the sole 2. The forefoot surface 4 and the heel surface 5 are in a cross-overlapping state near the heel on both sides of the shoe, and in the overlapping position, the heel surface 5 is located on the inner side of the forefoot surface 4.

[0042] At the same time, the forefoot surface 4 and the heel surface 5 cooperate to form a shoe opening on the upper 3 of the shoe, and the two cooperate to form the shoe cavity of the shoe, and the shoe opening is connected to the shoe cavity, and the user can insert the foot into the shoe cavity. By separating the forefoot surface 4 from the heel surface 5, the relatively stable structure of the forefoot surface 4 itself will not affect the deformation of the heel surface 5, and the front edge of the heel surface 5 is tilted forward, so that the heel surface 5 has a better deformation ability; in addition, the heel surface 5 and the forefoot surface 4 have an overlapping part, which can ensure that the upper 3 has sufficient wrapping for the user's foot.

[0043] Reference Figure 1 and Figure 2 The elastic heel 6 is an independent component and can be fixedly connected to the body 1. The elastic heel 6 mainly includes a deformation part 7, an upper wing part 12, a lower wing part 13 and a connecting part 14. The deformation part 7 is located at the midline of the elastic heel 6, the upper wing part 12 and the lower wing part 13 each have two, and are respectively located at the two sides of the elastic heel 6 corresponding to the midline, and the connecting part 14 is located at the bottom of the elastic heel 6 and corresponds to the lower wing part 13 and the deformation part 7.

[0044] The lower end of the deformation part 7 is connected to the sole 2, and the deformation part 7 is connected to the outer surface of the heel surface 5 at least in the deformation section 9, so that the deformation part 7 is located at the rear end of the body 1. Figure 3 and Figure 4The upper part of the deformation part 7 is the slide-in section 8, and the inner surface of the slide-in section 8 extends obliquely from top to bottom and from back to front, so that the inner side of the slide-in section 8 forms a shape with a backward angle; the deformation section 9 smoothly connects with the slide-in section 8 and is located in the middle and lower parts of the deformation part 7. The deformation section 9 will deform and accumulate elastic potential energy when it is compressed. After the compression is removed or reduced to a critical value, the deformation section 9 will release the accumulated elastic potential energy to restore the original shape. The deformation and restorable deformation characteristics of the deformation section 9 are related to the material and structure of the deformation section 9. In this embodiment, the elastic heel 6 is made of TPU or TPEE material, which has good elasticity and wear resistance.

[0045] When the user puts on the shoe, he can first extend the front section of the foot into the shoe cavity of the shoe from the shoe opening formed by the forefoot surface 4 and the heel surface 5. Due to the obstruction of the instep position of the forefoot surface 4, the user's foot cannot completely enter the shoe cavity. At this time, the user's heel will contact the heel surface 5 and first contact the sliding section 8 of the elastic heel 6. Since the inner surface of the sliding section 8 extends obliquely from top to bottom and from back to front to form a backward state, a larger part of the user's heel will fit into the sliding section 8, and the heel of the foot can be inserted into the shoe cavity more smoothly; then the user's heel applies force to the elastic heel 6, causing the deformation section 9 to be compressed and deformed, and the elastic heel 6 is pressed downward as a whole. At the same time, since the forefoot surface 4 and the heel surface 5 are separated The structure is separated, so the parts of the heel surface 5 on both sides of the shoe will be deformed as the elastic heel 6 is pressed down, and this deformation will not be constrained by the forefoot surface 4. The deformation degree of the heel surface 5 is greater and the deformation range is controllable. After that, the front section of the user's foot can continue to extend forward into the shoe cavity until the user's heel also extends into the shoe cavity. At this time, the pressure degree of the user's heel on the deformation part 7 of the elastic heel 6 is reduced. Under the action of the deformation part 7, the elastic heel 6 restores its original shape and drives the heel surface 5 to restore its deformation, thereby completing the shoe-wearing action. At this time, the deformation part 7 fits the heel of the foot and can restrain the foot, thereby preventing the shoe from falling off. When taking off the shoe, fix the heel of the shoe and lift the foot from the shoe cavity.

[0046] Reference Figure 3 and Figure 4 The outer surface of the deformation part 7 is provided with a plurality of ridges 10 at intervals from top to bottom in the deformation section 9; the height of the ridges 10 starts from the position corresponding to the midline of the shoe and gradually decreases toward the sides of the shoe. The inner surface of the deformation part 7 is provided with a plurality of grooves 11 at intervals from top to bottom in the deformation section 9, and the grooves 11 are in the shape of long strips extending along the sides of the shoe. And each ridge 10 on the deformation part 7 corresponds to the position of a groove 11 in the up-down direction.

[0047] Specifically, three ridges 10 are protruding from the outer side of the deformation part 7 corresponding to the position of the deformation section 9. The three ridges 10 are arranged at approximately equal intervals from top to bottom, and the three ridges 10 have a certain length in the width direction of the shoe. At the same time, the protruding heights of the three ridges 10 relative to the outer surface of the deformation part 7 vary. The height of the ridges 10 gradually decreases from the middle position to both sides, that is, the middle position is protruding and the two sides gradually approach the outer surface of the deformation part 7. The provision of the ridges 10 makes the deformation section 9 of the deformation part 7 change the structure of uniform thickness in the conventional design. When the deformation part 7 is compressed and deformed, the ridges 10 can pull the two sides of the deformation part 7, so that the deformation part 7 is only bent in the front-to-back direction without deflection. Therefore, its performance in recovering deformation is better, and the structure is less prone to material fatigue, and can have a longer service life.

[0048] The inner side of the deformation part 7 is concavely provided with three grooves 11 corresponding to the position of the deformation section 9. The three grooves 11 are arranged at approximately equal distances from top to bottom, and the three grooves 11 have a certain length in the width direction of the shoe, so the three grooves 11 are in the shape of long strips extending to both sides of the width direction of the shoe. When the elastic heel 6 is deformed, the presence of the grooves 11 can make the elastic heel 6 deform in a preset manner, thereby avoiding the elastic heel 6 from piling up when being compressed, making the structure less prone to material fatigue and having a longer service life; and the deformation part 7 has a certain length in the up and down direction, which makes it easy for the deformation part 7 to be affected by its own material properties and break. By providing the grooves 11, the deformation part 7 can also have a better deformation ability, avoiding the elastic heel 6 from breaking due to frequent compression.

[0049] Each ridge 10 on the deformation portion 7 corresponds to a groove 11 in the up and down direction, further constraining the deformation mode of the elastic heel 6, improving the deformation recovery ability of the elastic heel 6, reducing the material fatigue of the elastic heel 6, and increasing the service life of the elastic heel 6.

[0050] Reference Figure 3 and Figure 4 The upper wing portion 12 is formed by the two side edges of the upper side of the deformation portion 7 extending forward and laterally, and is connected to the outer surface of the heel surface 5. The lower wing portion 13 is formed by the two side edges of the lower side of the deformation portion 7 extending forward and laterally, and is fixed to the sole 2. The edges of the deformation portion 7 on both sides of the shoe are smoothly transitioned and connected to the upper wing portion 12 and the lower wing portion 13.

[0051] Specifically, the length of the upper wing 12 extending forward is shorter than that of the lower wing 13, and the position of the upper wing 12 in the vertical direction roughly corresponds to the lower section of the sliding section 8 and the upper section of the deformation section 9. The upper wing 12 can improve the wrapping of the elastic heel 6 on the heel surface 5, thereby improving the wrapping performance of the shoe on the heel of the foot. At the same time, the upper wing 12 can also increase the contact area between the elastic heel 6 and the user's foot when the user wears the shoe, and the user can easily press down to deform the elastic heel 6. The lower wing 13 extends forward for a longer length, which can increase the area where the elastic heel 6 is connected with the sole 2 and the heel surface 5. The lower wing 13 can improve the overall support performance of the elastic heel 6. The deformation of the deformation part 7 is not only generated relative to the sole 2, but also relative to the lower wing 13. The elastic heel 6 formed by the lower wing 13 and the deformation part 7 has a higher deformation capacity. After the user's foot enters the shoe cavity to a certain extent, the elastic heel 6 can restore the deformation by itself, thereby improving the wearing efficiency and comfort. The edges of the deformation part 7 on both sides of the shoe are smoothly transitioned to the upper wing part 12 and the lower wing part 13 to avoid stress concentration caused by abrupt transitions, which can effectively improve the overall deformation performance of the elastic heel 6.

[0052] Reference Figure 3 and Figure 4 The position of the uppermost ridge 10 on the deformation part 7 in the vertical direction corresponds to the upper wing part 12, and the length of the ridge 10 on the deformation part 7 in the direction of both sides of the shoe decreases first and then increases from top to bottom. The shape and size of the ridge 10 are adapted to the size of the elastic heel 6 as a whole in the direction of both sides of the shoe, which can ensure that the ridge 10 has a maximized auxiliary effect at each position of the deformation part 7 and has a more harmonious appearance.

[0053] In addition, a connecting portion 14 is provided at the bottom of the elastic heel 6 , and the connecting portion 14 is embedded in the sole 2 to fix the elastic heel 6 to the sole 2 . The connecting portion 14 can improve the firmness of the connection between the elastic heel 6 and the sole 2 , and provide a basis for the deformation of the elastic heel 6 .

[0054] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
