Description

Technical Field

[0001] The utility model relates to the technical field of shoe components, in particular to a heel back lining with an extended edge. Background Art

[0002] A heel counter is a reinforcing material used on the heel of a shoe. Its primary function is to maintain the shoe's shape and prevent deformation. It's typically placed between the lining and the upper at the toe and heel areas, providing support and stability. This ensures the heel remains straight and stable, making the shoe's structure more rigid and less prone to deformation, thereby maintaining its flawless appearance and comfortable fit.

[0003] Generally, the uppers of leather shoes are relatively thin. If traditional backing is used, bulges are likely to appear on the upper, affecting the appearance of the leather shoes. If a thinner backing is used, the support and wrapping of the heel are insufficient, and the heel is likely to slip out of the shoe when walking, affecting the comfort of the leather shoes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a heel back lining with an extended edge.

[0005] The purpose of the utility model can be achieved through the following technical solution: a heel lining with an extended edge, comprising a lining body, an extended edge is provided at the bottom of the lining body, a transition edge from thick to thin is provided on the outer side of the edge of the lining body, and the lining body has a U-shaped structure.

[0006] Preferably, the back lining body is formed as a whole by welding the TPU sheet and the lining sheet into one piece through a hot pressing mold.

[0007] Preferably, the side wall of the rear lining body is an arc-shaped structure.

[0008] Preferably, a reinforcing cloth is bonded to the inner side of the rear lining body.

[0009] Preferably, a positioning notch is provided in the middle of the transition edge.

[0010] Preferably, the side of the rear lining body is in an arc-shaped structure transitioning from high to low.

[0011] The beneficial effect of the utility model is that the outer edge of the back lining body is chamfered to form a transition edge from thick to thin, thereby preventing convex marks from being generated on the upper of the leather shoe after the back lining body is installed inside the shoe, so that the back lining body can provide support without affecting the appearance of the leather shoe.

[0017] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0019] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] See Figures 1 to 3As shown, the structure of the utility model is: a heel back lining with an extension, including a back lining body 1, a bottom of the back lining body 1 is provided with an extension 101, so that the sole can be fixed to the extension 101 by gluing, sewing, etc., thereby improving the firmness of the installation and preventing the back lining body 1 from falling off, and the outer side of the edge of the back lining body 1 is provided with a transition edge 102 from thick to thin, and the outer side of the edge of the back lining body 1 is chamfered to form the transition edge 102 from thick to thin, thereby preventing the back lining body 1 from being installed inside the shoe and generating convex marks on the upper of the leather shoe. The back lining body 1 has a U-shaped structure, which can fit the upper of the heel of the leather shoe well, thereby supporting and shaping the contour of the heel of the leather shoe.

[0021] Furthermore, the back lining main body 1 is formed as a whole by welding the TPU sheet 105 and the lining sheet 106 into one. Specifically, after the TPU sheet 105 is heated and melted, the lining sheet 106 is placed on the melted TPU sheet 105 to weld the lining sheet 106 and the TPU sheet 105 into one. After the TPU sheet 105 is cured, it is placed in a hot pressing mold. The mold is heated to soften the TPU sheet 105 to form the outline of the back lining main body 1. The lining sheet 106 not only improves the strength of the back lining main body 1, but also plays a shaping role after the back lining main body 1 is formed.

[0022] like Figures 1 to 2 As shown, the side wall of the rear lining body 1 is an arc-shaped structure. Specifically, the arc-shaped structure can better fit the shape of the heel, improve the comfort when wearing, and at the same time wrap the heel to prevent the heel from slipping out when walking.

[0023] like Figure 1 As shown, a reinforcing cloth 103 is bonded to the inner side of the back lining body 1. Specifically, when installing the back lining body 1, the back lining body 1 needs to be heated to soften the TPU material on the outer side of the back lining body 1, and then bonded between the lining and the upper. By bonding the reinforcing cloth 103 to the inner side of the back lining body 1, not only can the TPU material be prevented from penetrating into the inner lining of the shoe, but the strength and support of the back lining body 1 can also be further improved.

[0024] like Figure 2 、 Figure 3 As shown, a positioning notch 104 is provided in the middle of the transition edge 102. Specifically, the positioning notch 104 mainly plays a positioning role. When installing the back lining body 1, the positioning notch 104 is aligned with the center position of the heel upper of the leather shoe to prevent the back lining body 1 from being installed offset.

[0025] like Figure 1As shown, the side of the back lining body 1 is an arc-shaped structure that transitions from high to low. Specifically, the upper and sole of leather shoes will bend along with the sole of the foot when walking. By designing the side of the back lining body 1 into an arc-shaped structure that transitions from high to low, the back lining body 1 is prevented from interfering with the deformation of the upper and sole during walking, thereby avoiding affecting the comfort of walking in the shoes.

[0026] During specific use, the outer side of the back lining main body 1 is heated and softened during installation, and then bonded between the lining and the upper. When the upper and the sole of the leather shoe are combined, the extension 101 can be fixed to the sole by gluing, sewing, etc., thereby improving the firmness of the installation and preventing the back lining main body 1 from falling off after the leather shoe is worn for a long time. After the back lining main body 1 is installed in the leather shoe, the outer side of the edge of the back lining main body 1 is chamfered to form a transition edge 102 from thick to thin, thereby preventing convex marks from occurring on the upper.

[0027] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
