Description

Technical Field

[0001] The invention belongs to the technical field of shoe manufacturing, and particularly relates to a shoe that is easy to put on by improving the shoe back support structure. The shoe optimizes the shoe opening design so that the heel can easily slide into the shoe, and the shoe can be put on and taken off without using hands or bending over. Background Art

[0002] Application No. CN2022207369553 discloses a heel-wrapping structure composed of a protective layer, a flexible layer, a hard plate, an outer layer, and a reinforcing rib. The lower part of the inner side of the second positioning portion is set to be concave outward, and the upper part is tilted upward and backward. The shoe is easy to put on and take off, and the foot is not easy to fall out when walking. This structure is an integral shoe back, the structure is too complicated, and the appearance visual design is single, which is easy to cause aesthetic fatigue.

[0003] Application No. CN 2022900002255 discloses a heel cup with uneven thickness, which can be deformed under stress and can adjust the width of the shoe opening when deformed. The rear end of the heel cup has an S-shaped cross-section. The heel cup is essentially an evolution of the cardboard of application No. CN2022207369553, and has no substantial contribution compared to the original application. Increasing the width of the shoe opening does not substantially solve the problem of difficulty in getting the shoe into the foot.

[0004] The main problem with shoes is that the longest diameter of the oval formed by the outer contour between the heel and the instep is larger than the longest diameter of the shoe opening, which makes it difficult for the heel to extend into the shoe by itself. The present invention aims to solve the problem of shoes being difficult to put on and take off quickly in the prior art by optimizing the support structure of the shoe back, while improving the aesthetics and practicality of the shoes. Summary of the invention

[0005] The invention provides a pair of shoes that are easy to wear, the core of which lies in the combination of the size of the shoe opening and the shape-preserving design of the shoe back.

[0006] The present invention optimizes the stretching design of the shoe opening to ensure that the shoe opening can form an elliptical opening in a natural state. When the shoe opening is stretched or expanded, the opening size of the ellipse is large enough to easily accommodate the elliptical contour formed by the minimum distance from the heel to the instep. Specifically, the maximum diameter of the elliptical opening formed after the shoe opening is stretched is larger than the maximum diameter of the ellipse formed by the shortest distance from the heel to the instep. This design ensures that the heel can slide smoothly into the shoe without causing difficulty in wearing the shoe due to insufficient shoe opening size.

[0007] Preferably, the shape-preserving harbor treasure includes the rear part and the left and right side wings.

[0008] Preferably, the left and right side wings are connected to the rear part to form a semi-enclosed structure facing the shoe cavity. This design not only enhances the support of the back of the shoe, but also ensures that the heel is not easily deformed when stepping on the upper edge of the shape-retaining support, thereby providing stable support.

[0009] Preferably, the heights of the ends of the left and right side wings away from the rear portion gradually decrease.

[0010] Preferably, the middle portion of the semi-enclosed structure in the up-down direction bulges away from the shoe cavity to form a shape that wraps the heel.

[0011] Preferably, the shape-retaining harbor guard has a supporting force, and the shape-retaining harbor guard is not easily deformed when the heel steps on the upper edge thereof.

[0012] Preferably, the upper end of the rear portion of the shoe upper is inclined and protrudes rearward and upward, forming a guide structure for the heel to slide into the shoe.

[0013] Preferably, when the heel of a human foot steps on the upper end of the shoe back, the heel slides down along the guide structure and slides into the shoe through the upper edge of the shape-retaining support without additional bending or hand assistance. This design significantly simplifies the process of putting on shoes, and is particularly suitable for the elderly, children or people with limited mobility.

[0014] Preferably, an extension portion extends from the top of the semi-enclosed structure and is inclined rearward and upward and is placed inside the guide structure at the upper rear end of the shoe upper.

[0015] Preferably, the connection between the extension part and the semi-enclosed structure is smoothly transitioned to form a raised structure toward the shoe cavity. In the side view, the highest point of the raised structure is closest to the toe direction compared with the shape-retaining support and the extension part. When the shoe is worn, the raised structure clamps the heel, making it difficult to fall off, preventing the foot from falling off, thereby ensuring the stability of the shoe. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The present invention discloses an overall structure of a shoe that is easy to wear.

[0017] Figure 2 It is a three-dimensional diagram of a shape-retaining support for a shoe that is easy to put on according to an embodiment of the present invention.

[0018] Figure 3 It is a longitudinal cross-sectional view of the rear central part of a shape-retaining shoe that is easy to put on according to an embodiment of the present invention.

[0019] In the figure: a shoe upper 1; a shoe sole 2; a shoe back 10; a guide structure 11, a shape-retaining support 100; a rear portion 101; two left and right side wings 102; an extension portion 104; and a raised structure 105. Specific embodiments

[0020] The structure and working principle of the present invention are described in detail below through specific embodiments. Shoe back 10 design

[0021] like Figure 1 As shown in FIG. 2 , the shoe 1 includes a sole 2 and a shoe upper 10. The shoe upper 10 includes a shape-retaining support 100, and the shape-retaining support 100 includes a rear portion 101 and two left and right side wings 102. The shape-retaining support 100 is made of a hard material, and its height gradually decreases toward the ends of the left and right side wings 102, forming a semi-enclosed structure facing the shoe cavity. The middle portion of the semi-enclosed structure in the upper and lower directions bulges away from the shoe cavity, forming a shape that wraps the heel.

[0022] Guide structure design The upper end of the rear part of the shoe back 10 is tilted and protruded backward and upward to form a guide structure. The inclination angle of the guide structure is 15° to 45°, ensuring that the heel can slide smoothly into the shoe when stepping on the upper end of the shoe back 10. Extension 104 design

[0023] like Figure 3 As shown, an extension portion 104 tilted upward and backward extends from the top of the semi-enclosed structure, and the connection between the extension portion 104 and the semi-enclosed structure smoothly transitions to form a raised structure 105 toward the shoe cavity. The highest point of the raised structure 105 is close to the toe direction, that is, in the longitudinal cross-section of the rear center of the shape-keeping port 100, the raised structure 105 is most prominent in the direction of the inside of the shoe cavity relative to the extension portion 104 and the semi-enclosed structure. This protruding structure can clamp the heel to ensure that the heel is not easy to fall off when the shoe is worn. Material selection

[0024] The rear part 101 of the shape-saving Gangbao 100 is made of hard resin material, which is not easily deformed by being stepped on. The sole is made of non-slip rubber material, and the upper is made of fabric material with good air permeability.

[0025] Through actual testing, the shoes of the present invention can easily slide the heel in, and can be put on and taken off without using hands or bending over. The shoes have good stability, the heel will not fall off when worn, and the appearance design is simple and beautiful, suitable for daily use. The present invention solves the problem that shoes are difficult to put on and take off quickly in the prior art by optimizing the size of the shoe opening, and the shape-preserving port 100 design and guide structure of the additional shoe back 10. Through verification of specific embodiments, the shoes of the present invention are not only easy to wear, but also have good support and aesthetics, and are suitable for use by all kinds of people.
