Description

Technical Field

[0001] This utility model relates to the field of shoe technology, and more specifically to a quick-wearing shoe with adjustable tightness. Background Technology

[0002] The existing shoe soles shown in "Application No.: CN201921503199.4, Shoe Sole and Walking Shoe" and "Application No.: CN201020293792.3, A Novel Shoe Sole" use multiple perforations as movement space to improve resilience;

[0003] The application number CN202323276874.3, "A quick-wearing shoe", proposes a quick-wearing structure (i.e., the top surface of the heel is inclined downwards, and a fixing component is embedded inside the heel, which shapes the opening of the heel to facilitate faster shoe-wearing).

[0004] Furthermore, the aforementioned quick-wear shoes are described as having "a sock liner on the inside of the upper, wrapped by the flyknit fabric of the upper, and the lacing structure is also on the outermost flyknit surface, making it easy to adjust the overall tightness to suit different individuals." When setting the position for the lacing, it is necessary to process the flyknit surface separately. In order to meet the rebound function, when the aforementioned perforated sole is used, setting the lacing position separately has the disadvantage of low functional utilization. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable-tightness quick-wearing shoe in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes an adjustable quick-wear shoe, including a sole and an upper fixed at the top. The upper is composed of a front soft cover and a heel cover that are connected and fixed together. The sole has multiple sets of perforations from left to right.

[0008] It also includes elastic components that secure the perforations and the upper;

[0009] The elastic component includes a fixing strap fixed to the top of the front soft cover, multiple sets of limiting holes formed between the fixing strap and the front soft cover, shoelaces threaded through the limiting holes and perforations, adjustable and stabilizing buckles movable on the shoelaces, and a tensioning strap that fits against the outer side of the heel cover.

[0010] The tension band is arc-shaped, and the two sides of the shoelace are attached to the ends of the tension band. When the end of the tension band is tightened, the front soft cover shrinks, and the adjustment and stabilizing buckle is fixed to the side of the shoelace near the end.

[0011] As a preferred embodiment of this utility model, the multiple sets of limiting holes are distributed sequentially from left to right.

Detailed Implementation Example 1:

[0026] like Figures 1-4 As shown, this embodiment proposes: an adjustable quick-wear shoe, including a sole 1 and an upper fixed to its top. The upper is composed of a front soft covering 2 and a rear heel covering 3 connected and fixed together. The sole 1 is provided with multiple sets of perforations 4 from left to right. The perforations 4 pass through the sole 1 from front to back.

[0027] The front soft cover 2 can be the shoe upper structure described in "CN202323276874.3" in the background technology: "a sock liner is provided on the inside of the shoe upper, and the sock liner is wrapped by the fly-knit fabric of the shoe upper", which has a soft deformation effect;

[0028] It also includes a fastening component 5 that is fixed between the perforation 4 and the shoe upper;

[0029] The elastic component 5 includes a fixing strap 51 fixed to the top of the front soft cover 2, multiple sets of limiting holes 52 formed between the fixing strap 51 and the front soft cover 2, shoelaces 53 passing through the limiting holes 52 and the perforation 4, an adjustment and stabilizing buckle 54 movable on the shoelaces 53, and a tensioning strap 55 that fits against the outside of the heel cover 3.

[0030] The tension band 55 is arc-shaped, and the two sides of the shoelace 53 are respectively attached to the ends of the tension band 55. When the end of the tension band 55 is tightened, the front soft cover 2 is retracted, and the adjustment and stabilizing buckle 54 is fixed on the side of the shoelace 53 near the end.

[0031] The fixing strap 51 and the tensioning strap 55 are made of nylon fiber braided strap or polyester (PET) braided strap;

[0032] The adjusting and stabilizing buckle 54 is a shoelace clamping buckle, such as the fixing device on "Application No.: CN202120544128.X", or "Application No.: CN202020639369.8, shoelace buckle";

[0033] like Figure 1As shown, when using the elastic component 5, the fixing strap 51 is first fixed to the front soft cover 2 by adhesive or sewing, and multiple limiting holes 52 are reserved. The shoelace 53 is first passed through the limiting holes 52, and then the two ends of the shoelace 53 are crossed and passed through the perforation 4 on the left side. Then, it is flipped upward and crossed through the limiting hole 52 again. This process is repeated multiple times according to the length and needs. Finally, the two ends of the shoelace 53 are attached to the two ends of the tensioning strap 55, which is pre-positioned against the right end of the heel cover 3. When the two ends of the shoelace 53 are tightened, the overall stability is improved. The tightness of the front soft cover 2 can be adjusted by setting the shoelace in this way. Finally, the two ends of the shoelace 53 are inserted into the adjusting and stabilizing buckle 54 and pressed into position. The adjustment of tightness is simple. The use of the perforation 4 as shoelace holes can further improve the utilization rate of the functional components.

[0034] Among them, multiple sets of limiting holes 52 are distributed sequentially from left to right; such as Figure 1 As shown, the shoelaces 53 can pass through the limiting holes 52 sequentially from left to right, increasing the area of ​​the shoelaces distributed on the front soft surface 2, making it more comfortable when adjusting the tightness.

[0035] The tension band 55 has tension holes at both ends for the shoelace 53 to pass through. The tension holes can be holes punched at both ends of the tension band 55, or the tension band 55 can be flipped over and attached together and fixed by adhesive or sewing, with a ring hole reserved between the flips, thus serving as the tension holes.

[0036] Among them, the material of the heel cover 3 is EVA; EVA (ethylene-vinyl acetate copolymer) is a lightweight, soft synthetic material with good elasticity and wear resistance;

[0037] The heel cover 3 is equipped with a "slip-on" structure, which is as follows: the top right side of the heel cover 3 is inclined towards the shoe opening, and the upper right side of the heel cover 3 is concave; due to the flexible rebound effect of EVA material, when the heel steps on the top right side of the heel cover 3, the pressure will create a fold at the concave position of the right side of the heel cover 3 to increase the entry point, and through the inclined guide surface, it will help the foot to enter the shoe, providing a quick-put effect;

[0038] The slip-on structure may be the quick-wear structure proposed in the background technology "CN202323276874.3", and it can be used on the heel cover 3. Example 2:

[0039] like Figures 1-4 As shown, the difference between this and Embodiment 1 is that: it also includes a side trim component 6 fixed at both ends of the heel cover 3, and the bottom end of the side trim component 6 is fixed to the top end of the sole 1; thus improving the overall aesthetic effect of the shoe.

[0040] The side trim component 6 includes a vertical piece 61, mounting holes 62 on the vertical piece 61, and decorative pieces 63 that are fixed to the vertical piece 61 through the mounting holes 62. The mounting holes 62 are provided in multiple sets and are evenly distributed on the vertical piece 61. The top of the vertical piece 61 is fixed to the heel cover 3, and the bottom of the vertical piece 61 is fixed to the sole 1. The decorative pieces 63 are fixed to the mounting holes 62, and multiple sets of decorative pieces 63 can be fixed in multiple positions and their positions can be adjusted.

[0041] Decorative component 63 includes a locking block 631, an annular groove 632 surrounding the locking block 631, and a decorative piece 633 fixed to the outside of the locking block 631. The locking block 631 is made of a flexible material; the locking block 631 is inserted into the mounting hole 62 until the annular groove 632 moves within the mounting hole 62; as Figure 2 As shown, by pressing the locking block 631 into the mounting hole 62, the locking block 631 will enter the mounting hole 62 under the deformation of the locking block 631. The pressing continues until the annular groove 632 is in the position of the mounting hole 62, and the depth of the annular groove 632 is not less than the thickness of the vertical piece 61, so as to ensure that the annular groove 632 can be stably placed in the mounting hole 62, and the assembly can be completed. The operation is simple.

[0042] Among them, the vertical strip 61 is made of TPU; by using this material to make the vertical strip 61, it can provide flexibility and support, thus providing support on the side of the heel cover 3 and improving a certain degree of resilience, increasing the functionality.

[0043] TPU (thermoplastic polyurethane) is a block copolymer composed of hard and soft segments. It combines the flexibility of rubber with the hardness of plastic, and has good abrasion resistance, oil resistance, chemical resistance and excellent mechanical properties, such as high tensile strength and good elasticity.
