[0007] Preferably, each of the protrusions is provided with a first isosceles trapezoidal block and a second isosceles trapezoidal block at its end. The two isosceles trapezoidal blocks are the same size and are arranged at an angular interval around the center of the circular hole. The second connecting plate is provided with an isosceles trapezoidal groove matching the size and shape of the first and second isosceles trapezoidal blocks on the bottom surface of each of the grooves. The isosceles trapezoidal groove is for the first and second isosceles trapezoidal blocks to be inserted into. When the first isosceles trapezoidal block is inserted into the isosceles trapezoidal groove, the first connecting plate and the second connecting plate are on the same plane. When the second isosceles trapezoidal block is inserted into the isosceles trapezoidal groove, the first connecting plate and the second connecting plate are bent relative to each other.

[0008] Preferably, the top surface of the forefoot portion is recessed with a first positioning groove matching the shape of the first connecting plate, and the top surface of the heel portion is recessed with a second positioning groove matching the shape of the second connecting plate. The first positioning groove and the second positioning groove are connected at the cut.

The top surface of the sole is covered with woven fabric, which is glued to the sole and cut at the cut.

[0009] Preferably, the opening and closing device further includes a flexible pad, which is attached to the upper surface of the first connecting plate and the second connecting plate. The area of ​​the flexible pad is greater than the sum of the areas of the upper surface of the first connecting plate and the second connecting plate. A third positioning groove is recessed on the top surface of the sole, which is used to accommodate and position the flexible pad. The flexible pad is pressed by the fabric.

[0010] Preferably, the forefoot upper has a groove at the top, the groove extending through the side of the forefoot upper near the heel upper, and multiple first elastic ribs are sewn into the forefoot upper at the groove, the multiple first elastic ribs being evenly distributed along the extension direction of the groove. A tongue is provided on the inner side of the forefoot upper, and one end of the tongue is sewn to the side of the forefoot upper away from the heel upper, and the tongue covers the groove.

[0011] Preferably, a second elastic rib is fixed on the side of the heel upper away from the forefoot upper, and the two ends of the second elastic rib extend from the opposite sides of the heel upper toward the forefoot upper and are sewn together with the forefoot upper.

[0012] Preferably, the heel upper has a forefoot extension on the side near the forefoot upper, and the forefoot extension extends into the inside of the forefoot upper.

[0013] The beneficial technical effects of this application are as follows:

[0014] 1. The sole is integrally molded from elastic material, allowing for bending under force. This bending of the forefoot and heel widens the opening and stretches the springs, causing the first and second connecting plates to bend and enlarge the openings in the heel and forefoot uppers, making it easy for the foot to slip on. Releasing the force on the forefoot and heel causes the springs to pull back, re-fitting the sides of the openings in the first and second connecting plates. This allows the heel and forefoot uppers to cover the foot, completing the shoe-wearing process. The steps are simple and the operation is convenient, enabling quick shoe-wearing.

[0015] 2. A protrusion is provided on the first connecting plate, and the protrusion is provided with a first isosceles trapezoidal block and a second isosceles trapezoidal block. The second connecting plate is provided with a groove for the protrusion to pass through. The bottom of the groove is recessed with an isosceles trapezoidal slot for the first and second isosceles trapezoidal blocks to be engaged. When the first isosceles trapezoidal block is engaged in the isosceles trapezoidal slot, the first and second connecting plates are on the same plane. When the second isosceles trapezoidal block is engaged in the isosceles trapezoidal slot, the first and second connecting plates are bent relative to each other, so that the first and second connecting plates are locked in both the same plane state and the relative bending state. The locking of the first and second connecting plates in the same plane state makes the shoe stable and the sole less likely to bend during walking, thus affecting stability. Furthermore, the locking of the first and second connecting plates in the bending state eliminates the need to apply force to the sole during shoe wearing, making the wearing process more convenient. Due to the inclined surface of the isosceles trapezoid, the first and second isosceles trapezoidal blocks can slide out of the isosceles trapezoidal slot to switch states when the second connecting plate is under force.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figure 1 A shoe that is easy to put on and take off includes a sole 1, which includes a forefoot portion 11 and a heel portion 12. The sole 1 is integrally molded from an elastic material so that the forefoot portion 11 and the heel portion 12 are set as a whole. The forefoot portion 11 is used to support the forefoot of the human foot, and the heel portion 12 is used to support the heel of the human foot. A heel upper 2 is provided on the upper side of the heel portion 12 for including the heel of the human foot. A forefoot upper 3 is provided on the upper side of the forefoot portion 11 for including the forefoot of the human foot. The top of the heel upper 2 is provided with an opening 21, through which the human foot is inserted so that the forefoot is inserted into the forefoot upper 3 and the heel is inserted into the heel upper 2 and is included.

[0024] Reference Figure 2-5To facilitate quick foot insertion, a shoe designed for easy wear also includes an opening and closing device 4. The top surface of the sole 1 has a downward-facing cutout 13 between the forefoot portion 11 and the heel portion 12. The opening and closing device 4 includes a first connecting plate 41, a second connecting plate 42, and a spring 43. The first connecting plate 41 has three protrusions 411 spaced apart at one end, and the second connecting plate 42 has three recesses 421 spaced apart at one end. The recesses 421 penetrate the upper and lower surfaces of the second connecting plate 42, and each recess 421 corresponds to one of the three protrusions 411. Each protrusion 411 has a circular hole 412 penetrating it from the side, and the three circular holes 412 are aligned. The second connecting plate 42 has a running track penetrating it from the side. A first connecting plate 41 has a shaped hole 422, through which a first connecting shaft 413 is inserted via multiple circular holes 412. The first connecting shaft 413 passes into the shaped hole 422, allowing the first connecting shaft 413 to move and avoid obstruction. A groove 423 is recessed on the bottom surface of the second connecting plate 42, connecting to the end of the mounting groove away from the shaped hole 422. A mounting groove is recessed at the bottom end of the second connecting plate 42 at the position of the clearance groove 421, extending to connect to the shaped hole 422. A semi-circular groove 424 is recessed on the side wall of the groove 423 near the shaped hole 422, into which a second connecting shaft 425 is inserted. A spring 43 (not shown in the figure) is installed in the mounting groove, with one end connected to the first connecting shaft 413 and the other end connected to the second connecting shaft 425. The spring 43 tightens the first connecting shaft 413 and the second connecting shaft 425, thereby tightening the first connecting plate 41 and the second connecting plate 42. By bending the first connecting plate 41 and the second connecting plate 42 towards each other, the spring 43 is further compressed, causing them to bend towards each other. Releasing the force on the first connecting plate 41 and the second connecting plate 42 returns them to their original position, at the same horizontal plane. The first connecting plate 41 is then fixed to the forefoot portion 11, and the second connecting plate 42... 2. The heel part 12 is connected and fixed, so that the first connecting plate 41 and the second connecting plate are pulled in opposite directions by the spring 43 to make the two sides of the cut 13 fit together. When putting on the shoes, the forefoot part 11 and the heel part 12 of the sole 1 are bent in opposite directions, which causes the first connecting plate 41 and the second connecting plate 42 to bend in opposite directions, thereby expanding the cut 13 and making the opening 21 formed by the heel upper 2 and the forefoot upper 3 larger to facilitate the human foot to easily put on the shoes. By releasing the force applied to the forefoot part 11 and the heel part 12, the spring 43 is pulled in opposite directions to make the first connecting plate 41 and the second connecting plate 42 fit together again, so that the heel upper 2 and the forefoot upper 3 cover the human foot and complete the shoe wearing. The steps are simple and the operation is convenient, so the shoes can be put on quickly.

[0025] Reference Figure 2-5Furthermore, each protrusion 411 has a first isosceles trapezoidal block 414 and a second isosceles trapezoidal block 415 at its end. The two isosceles trapezoidal blocks are the same size and are arranged at an angular interval around the center of the circular hole 412. The angle between the first isosceles trapezoidal block 414 and the second isosceles trapezoidal block 415 is preferably greater than 90° and less than 120°. The second connecting plate 42 has an isosceles trapezoidal groove 426 on the bottom surface of each of the grooves 421, which matches the size and shape of the first isosceles trapezoidal block 414 and the second isosceles trapezoidal block 415. The isosceles trapezoidal groove 426 is for the first isosceles trapezoidal block 414 and the second isosceles trapezoidal block 415 to be inserted into. When the first isosceles trapezoidal block 414 is inserted into the isosceles trapezoidal groove 426, the first connecting plate 41 and the second connecting plate 42 are on the same plane. When the second isosceles trapezoidal block 415 is inserted into the isosceles trapezoidal groove 426, the first connecting plate 41 and the second connecting plate 42 are on the same plane. The connecting plate 41 and the second connecting plate 42 are bent relative to each other, and the first isosceles trapezoidal block 414 and the second isosceles trapezoidal block 415 are limited by the isosceles trapezoidal groove 426, so that the first connecting plate 41 and the second connecting plate 42 are locked in both the same plane state and the relative bending state. The locking of the first connecting plate 41 and the second connecting plate 42 in the same plane state makes the shoe stable and the sole 1 less likely to bend during walking, thus affecting stability. Furthermore, the locking of the first connecting plate 41 and the second connecting plate 42 in the bending state eliminates the need to apply force to the sole 1 during the wearing process, making the wearing process more convenient. Due to the inclined surface of the isosceles trapezoid, the first isosceles trapezoidal block 414 and the second isosceles trapezoidal block 415 can slide out of the isosceles trapezoidal groove 426 to switch states when the second connecting plate 42 is subjected to force. The switching is achieved by the force applied by the ball of the foot during the wearing process.

[0026] Reference Figure 4 Furthermore, the first connecting plate 41 is provided with an abutment edge 416 on the end face between two adjacent protrusions. The abutment edge 416 is used to abut against the second connecting plate 42. When the second connecting plate 42 abuts against the abutment edge 416, the first connecting plate 41 and the second connecting plate 42 are on the same horizontal plane, making the shoe more stable and the sole 1 less likely to bend during walking, thus affecting stability.

[0027] Reference Figure 2Furthermore, the top surface of the forefoot portion 11 is recessed with a first positioning groove 14 matching the shape of the first connecting plate 41, and the top surface of the rear foot portion is recessed with a second positioning groove 15 matching the shape of the second connecting plate 42. The first positioning groove 14 and the second positioning groove 15 communicate at the cut 13. The first connecting plate 41 is inserted into the first positioning groove 14, and the second connecting plate 42 is inserted into the second positioning groove 15. The opening and closing device 4 also includes a flexible pad 44, which is attached to the upper surfaces of the first connecting plate 41 and the second connecting plate 42. The area of ​​the flexible pad 44 is larger than that of the first connecting plate 41 and the second connecting plate 42. The sum of the surface areas of the connecting plate 42, the top surface of the shoe sole 1 is recessed with a third positioning groove 16, the third positioning groove 16 is used to accommodate and position the flexible pad 44, so that the upper surface of the flexible pad 44 is flush with the upper surface of the shoe sole 1, the top surface of the shoe sole 1 is covered with a woven fabric, the woven fabric is glued to the shoe sole 1, the flexible pad 44 is confined in the third positioning groove 16 by the woven fabric to realize the connection and fixation between the opening and closing device 4 and the shoe sole 1, the woven fabric is cut at the cut 13 to avoid hindering the bending of the shoe sole 1, the interface gap between the first connecting plate and the second connecting plate is eliminated by the flexible pad 44, making the shoe sole 1 more comfortable to wear.

[0028] Reference Figure 2-5 Furthermore, the forefoot portion 11 is provided with a first limiting post 17 on the bottom surface of the first positioning groove 14, and the heel portion 12 is provided with a second limiting post 18 on the bottom surface of the second positioning groove 15. The first connecting plate 41 is provided with a first through groove 417 matching the size of the first limiting post 17, and the second connecting plate 42 is provided with a second through groove 427 matching the size of the second limiting post 18. The first connecting plate 41 is limited in movement by the first limiting post 17 passing through the first through groove 417, and the second connecting plate 42 is limited in movement by the second limiting post 18 passing through the second through groove 427. This makes the installation of the first connecting plate 41 and the second connecting plate 42 more stable and less prone to displacement during bending and recovery.

[0029] Reference Figure 1 Furthermore, a slot 31 is provided at the top of the forefoot upper 3, extending through the side of the forefoot upper 3 near the heel upper 2. Multiple first elastic ribs 32 are sewn into the forefoot upper 3 at the slot 31, and the multiple first elastic ribs 32 are evenly distributed along the extension direction of the slot 31. A tongue 33 is provided on the inner side of the forefoot upper 3, and one end of the tongue 33 is sewn to the side of the forefoot upper 3 away from the heel upper 2. The tongue 33 covers the slot 31. The first elastic ribs 32 pull on both sides of the slot 31, so that the forefoot upper 3 has elastic opening performance, which is convenient to adapt to different sizes of feet and has better foot wrapping performance. At the same time, when wearing, the forefoot upper 3 is stretched open to make it easier to put on. The design of the tongue 33 prevents the forefoot upper 3 from being exposed to air through the slot 31, reducing the impact on the shoe's warmth performance. The tongue 33 fits the foot, making it more comfortable to wear.

[0030] Reference Figure 1 Furthermore, a second elastic rib 22 is sewn and fixed on the side of the heel upper 2 away from the forefoot upper 3. The two ends of the second elastic rib 22 extend from the opposite sides of the heel upper 2 toward the forefoot upper 3 and are sewn together with the forefoot upper 3. The second elastic rib 22 pulls the forefoot upper 3 and the heel upper 2 toward each other, so that the two sides of the cut 13 of the sole 1 fit together, making the sole 1 less likely to bend when walking, thus increasing the stability of the shoe.

[0031] Reference Figure 1 Furthermore, a forefoot extension 23 is provided on the side of the heel upper 2 near the forefoot upper 3. The forefoot extension 23 extends into the inside of the forefoot upper 3. The forefoot extension 23 causes the straight gap of the heel upper 2 to form a misaligned gap, reducing air permeability and making the shoe warmer.
