Shoe rear cover structure with springback function

Abstract

The utility model provides a shoe rear cover structure with a springback function. The shoe rear cover structure comprises a springback frame and a lead-in piece. Wherein the springback frame and the guide-in piece are both embedded in the shoe rear sleeve, and the guide-in piece is folded backwards and outwards at the shoe opening position. When the shoe is worn, after a foot sole extends into a shoe from a shoe opening, the heel can press the springback frame downwards in the process of pedaling into the shoe under the guide of the guide-in piece, so that the upper edge of the frame body, the connecting rib and the elastic rib are all compressed downwards to deform, the height of the shoe rear cover is reduced, and the heel can be conveniently and directly pedaled into the shoe. And after the heel is completely put into the shoe, the rebound frame loses limitation, so that the connecting rib and the elastic rib recover deformation and are automatically supported upwards, and a shoe rear cover wrapping the heel is formed again. In the shoe wearing process, the shoe rear cover does not need to be held by hands, the heel only needs to be pedaled into the shoe along the guide-in piece, convenience and labor saving are achieved, the two hands do not need to make contact with the shoe, and therefore sanitation is achieved.

Description

Technical Field

[0001] The utility model relates to the field of shoe structures, in particular to a shoe back cover structure with a rebound effect. Background Art

[0002] Shoes can prevent the feet from being hurt during walking or sports, and provide stable support and safety. The back cover of the shoe is used to protect the heel, so it has a certain height.

[0003] However, when putting on shoes, due to the high height of the shoe cover, it is difficult to put the heel into the shoe, and the shoe cover needs to be pulled hard, and then the heel needs to be pushed hard into the shoe. This way of putting on shoes is time-consuming and laborious, and is unhygienic. Utility Model Content

[0004] In view of the deficiencies of the above-mentioned background technology, the utility model provides a shoe back cover structure with a rebound effect.

[0005] The utility model adopts the following technical solutions:

[0006] A shoe back cover structure with a rebound effect, the shoe back cover structure comprising:

[0007] A rebound frame, wherein a plurality of elastic ribs are distributed on the surface of the rebound frame, the elastic ribs are bent in a wave shape, and the elastic ribs are arranged obliquely, and a concave embedding groove is arranged on the upper side of the rebound frame facing outward;

[0008] An introduction sheet, wherein the introduction sheet is in an arc-shaped structure, and the upper end of the introduction sheet is folded outward;

[0009] The introduction piece is embedded in the embedding groove, and the rebound frame and the introduction piece are both embedded in the shoe rear cover, so that the introduction piece is folded backward and outward at the shoe opening.

[0010] In a possible implementation, the rebound frame includes a frame body, connecting ribs and the elastic ribs. The frame body is an arc-shaped structure that covers the heel, and the middle of the frame body is hollow. The connecting ribs are arranged in the middle of the frame body, and the two ends of the connecting ribs are respectively connected to the two sides of the frame body. Several elastic ribs are connected between the frame body and the connecting ribs, and a compression gap is formed between two adjacent elastic ribs.

[0011] In a possible implementation, the shoe rear cover structure further includes a positioning sleeve, which is fixed at the heel position in the shoe and is wrapped around the lower end of the rebound frame.

[0012] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: when wearing the shoes provided with the utility model, after the sole of the foot extends into the shoe from the shoe opening, the heel can press down the rebound frame during the process of stepping into the shoe under the guidance of the introduction sheet, so that the upper side of the frame, the connecting ribs and the elastic ribs are all compressed downward and deformed, thereby reducing the height of the shoe back cover, so that the heel can be directly stepped into the shoe more conveniently, and after the heel is completely inserted into the shoe, the rebound frame loses its restriction, so that the connecting ribs and the elastic ribs can restore their deformation and automatically prop up, forming the shoe back cover that wraps the heel again. This shoe-wearing process only requires the heel to step into the shoe along the introduction sheet, which is very convenient and labor-saving, and does not require both hands to touch the shoe, so it is also more hygienic.

[0018] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0019] In the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the change of the orientation of the components in the drawings.

[0020] The utility model provides a shoe back cover structure with a rebound effect, as shown in the attached Figure 1 and 2 As shown, the shoe rear cover structure includes a rebound frame 2, an introduction piece 3 and a positioning sleeve 4. A concave embedding groove 201 is provided on the upper side of the rebound frame 2 facing outward, and the introduction piece 3 fits in the embedding groove 201, and the rebound frame 2 and the introduction piece 3 are both embedded in the shoe rear cover 11.

[0021] As attached Figure 2 and 5As shown, the positioning sleeve 4 is a C-shaped semi-enclosed structure, and the positioning sleeve 4 wraps the lower end side of the rebound frame 2, so that the rebound frame 2 is confined in the positioning sleeve 4. Preferably, the shoe rear cover 11 includes an inner layer and an outer layer, and the inner layer and the outer layer clamp and wrap the side of the rebound frame 2, the side of the positioning sleeve 4 and the guide piece 3. This structure can limit the rebound frame 2 to the position of the shoe rear cover 11, and prevent the rebound frame 2 from shaking left and right when the rebound frame 2 is stepped on.

[0022] Please refer to the attached Figures 1 to 3 As shown, the guide piece 3 is in an arc shape, and the upper end of the guide piece 3 is folded outwards, and the guide piece 3 is embedded in the embedding groove 201, so that the upper end of the guide piece 3 at the shoe opening is folded backwards and outwards. When wearing shoes, the structure of the guide piece 3 can play a guiding role, making it easier for the heel to step into the shoe.

[0023] As attached Figure 4 As shown, the rebound frame 2 includes a frame 21, a connecting rib 22 and an elastic rib 23, wherein the frame 21, the connecting rib 22 and the elastic rib 23 are integrally formed by an injection molding process to form the overall structure of the rebound frame 2. Preferably, the rebound frame 2, the introduction sheet 3 and the positioning sleeve 4 can all be made of TPU. The frame 21 is an arc-shaped structure covering the heel, and the middle of the frame 21 is hollowed out, and the embedding groove 201 is arranged on the periphery above the frame 21. The connecting rib 22 is arranged in the middle of the frame 21, and the two ends of the connecting rib 22 are respectively connected to the two sides of the frame 21, which is equivalent to the connecting rib 22 being arranged in the middle of the hollow position on the back of the frame 21, and the extension direction of the connecting rib 22 is consistent with the setting angle of the upper side of the frame 21, and both sides are inclined upward. This structure enables the upper side of the frame 21 and the connecting rib 22 to have elastic force to rebound upward after being pressed down. A plurality of elastic ribs 23 are connected between the frame 21 and the connecting ribs 22, that is, a plurality of elastic ribs 23 are provided at both the upper and lower ends of the connecting ribs 22, and the elastic ribs 23 form a structure supporting the connecting ribs 22 and the frame 21. A compression gap 202 is formed between two adjacent elastic ribs 23, and the compression gap 202 is the gap required when the rebound frame 2 is compressed as a whole. Furthermore, the structure in which the elastic ribs 23 connect the frame 21 and the connecting ribs 22 enables the rebound frame 2 to form a mesh frame structure as a whole, so as to support the entire shoe cover 11, so that the shoe cover 11 keeps covering the heel.

[0024] Continue to refer to the attached Figure 4 The elastic ribs 23 are bent into a wave shape, and the elastic ribs 23 are arranged obliquely. This structure allows the elastic ribs 23 to be compressed downward to a straight state when subjected to the downward pressure of the heel, thereby forming a state in which the upper and lower sides of each frame 21 and the connecting ribs 22 and the elastic ribs 23 are superimposed and fitted after compression. When the rebound frame 2 loses pressure, the elastic ribs 23 return to an inclined state under the elastic force of restoring deformation, so that the rebound frame 2 automatically recovers as a whole to form a mesh frame structure. In other words, the structure of the elastic ribs 23 allows the overall compression of the rebound frame 2 to have better resilience.

[0025] When wearing the shoe of the utility model, after the sole of the foot is inserted into the shoe from the shoe opening, the heel can press down the rebound frame 2 during the process of stepping into the shoe under the guidance of the introduction piece 3, so that the upper side of the frame 21, the connecting ribs 22 and the elastic ribs 23 are all compressed downward and deformed, thereby reducing the height of the shoe rear cover 11, so that the heel can be directly stepped into the shoe more conveniently, and after the heel is completely inserted into the shoe, the rebound frame 2 loses its restriction, and the connecting ribs 22 and the elastic ribs 23 can restore their deformation and automatically prop up, forming the shoe rear cover 11 that wraps the heel again to protect the heel. In this shoe-wearing process, there is no need to carry the shoe rear cover 11 by hand, and the heel only needs to be stepped into the shoe along the introduction piece 3, which is very convenient and labor-saving, and there is no need to touch the shoes with both hands, so it is also more hygienic.

[0026] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
