Description

TECHNICAL FIELD

[0001] The utility model discloses an automatic tightening shoe's upper structure belongs to footwear technical field. BACKGROUND

[0002] The shoelace is used for adjusting the tightness of the upper, and guarantees the comfort of the foot, and the shoelace always adopts the shoelace crossing knot mode, and the shoelace crossing knot mode is very tedious, and the shoelace is often too tight, too loose and loose when walking and moving, which causes a lot of inconvenience.

[0003] Therefore, many shoes with special structures for automatically binding the shoelace appear on the market, but these binding devices are generally arranged on the tongue or the vamp, and the tightness of the shoelace arranged on the top of the tongue is adjusted, but these shoes still need to be bent to manually rotate the knob to tighten the shoelace, which is inconvenient for people with bad back, so the automatic tightening shoe with patent application number CN200880019973.2 appears, which sets the tightening device at the heel, and adopts the mode of rolling the device by lifting the toe to tighten the shoelace, so that it is not necessary to bend.

[0004] However, the installation and stable structure of the pull rope in the above patent is relatively simple, and the stability of the pull rope is realized by fixing the pipe in the upper, and the pipe is directly fixed in the upper, first, when the pull rope is tightened, the tightening force point at the rear side of the upper will be concentrated on the two pipes, so that the upper cannot be well fitted to the heel of the wearer after being tightened, and the comfort is affected, second, the pipe is relatively long, and the force direction remains on the same side, so no matter what kind of fixing mode is used, displacement is likely to occur under the action of the pull force for a long time, and the displacement of the position will reduce the overall binding effect, third, the pipe is directly fixed in the upper, so that only manual positioning can be used for processing, and the production efficiency is low, therefore, a new scheme needs to be proposed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] The shoe upper structure in this application is applied to shoes with a tightening device, specifically a device located at the heel that can be rotated to wind up a cord, such as the tightening device structure in patent application number CN200880019973.2 mentioned in the background section of the specification. Of course, other existing devices that achieve this purpose can also be used. The specific structure of the tightening device is not within the scope of protection claimed in this application. An automatic tightening shoe upper structure, such as... Figure 1 , Figure 2 As shown, it includes an outer fabric piece 1, which is set as a semi-enclosed piece at the back of the shoe upper. The top has a curved part for lifting the shoe upper and providing guidance for the wearer's foot when wearing the shoe. The sides also include extensions 9 extending toward the front of the ankle. The extensions 9 allow the tube for tightening the shoe to be processed, combined and adjusted together with the back of the shoe upper, increasing production efficiency.

[0021] like Figure 1 As shown, a rope tube stabilizing assembly 3 is symmetrically arranged on the inner side of the outer layer fabric piece 1. The rope tube stabilizing assembly 3 includes a tightening rope 4, a guide tube 5, and a stabilizing member 6. The stabilizing member 6 is fixed to the inner side of the outer layer fabric piece 1 and is inclined along the extension 9. The guide tube 5 is disposed inside the stabilizing member 6. The two ends of the tightening rope 4 pass through the guide tubes 5 on both sides of the outer layer fabric piece 1, and protrude from the bottom of the guide tubes 5 to connect with the tightening device. The guide tubes 5 can guide the direction of the tightening rope 4. Figure 3 As shown, the extension 9 is provided with a rope hole 10. The tightening rope 4 extends from the rope hole 10 into the inside of the shoe upper and is guided by the guide tube 5 from the extension 9 to the bottom rear side of the outer layer fabric piece 1.

[0022] like Figure 4As shown, the stabilizing component 6 is an injection-molded sheet with a top profile that matches the extension 9. It has an overall backward-curved shape. A positioning groove 11 is provided on the side of the stabilizing component 6 away from the outer fabric sheet 1. The positioning groove 11 is positioned at the middle of the stabilizing component 6 along its curvature. The guide tube 5 is positioned along the positioning groove 11, with a portion of its bottom embedded within the positioning groove 11. A limiting tube wall 12 is provided at the positioning groove 11 on the stabilizing component 6. The limiting tube wall 12 has a semi-annular cross-section, and its inner diameter is equal to the outer diameter of the guide tube 5. The tube 5 is embedded in the channel formed between the positioning groove 11 and the limiting tube wall 12, thus being stably guided. It also serves to limit and support the guide tube 5. Even after long-term use, the guide tube 5 will not deviate or tilt, thus ensuring the long-term stability of the tightening effect. Furthermore, the cooperation between the positioning groove 11 and the limiting tube wall 12 simplifies the installation of the guide tube 5. The bending direction of the guide tube 5 can be determined simply by threading it through, thus avoiding the trouble of manual positioning. CNC equipment can even be used for threading to achieve maximum production efficiency.

[0023] like Figure 2 , Figure 4 As shown, the top of the stabilizer 6 is also provided with a second loop hole 13, which is aligned with the first loop hole 10. The guide tube 5 extends along the limiting tube wall 12 to the bottom of the outer layer fabric piece 1 and extends to the outside of the shoe upper. Therefore, when the tightening rope 4 is tightened, its forward pressure will be first dispersed by the guide tube 5 to the limiting tube wall 12. The limiting tube wall 12 will then form a pulling force on the stabilizer 6, further dispersing the direction of the force. Finally, the stabilizer 6 forms a pulling force on the shoe upper, making the shoe upper shrink and fit snugly against the ankle. The stabilizer 6 has a sheet-like body, and the connection area between it and the outer layer fabric piece 1 is large, making the connection more secure and stable. When transmitting the pulling force, it can also be dispersed more widely and evenly, making the fit of the shoe upper better and the wearing more comfortable.

[0024] like Figure 1 , Figure 2 As shown, a sponge component 7 is provided on the side of the rope tube stabilizing component 3 away from the outer fabric piece 1, and an inner fabric piece 8 is provided on the side of the sponge component 7 away from the outer fabric piece 1. The inner fabric piece 8 is pressed onto the outer fabric piece 1. The sponge component 7 can be made into different shapes using sponges with different rebound strengths and softness according to needs and styles, to increase the tactile feel between the shoe upper and the wearer's feet, thereby increasing comfort.

[0025] like Figure 1 , Figure 2As shown, a stabilizing buckle 14 is provided on the outer side of the outer fabric piece 1. The stabilizing buckle 14 passes through the first loop hole 10 and the second loop hole 13 respectively, and is fixed to the outer fabric piece 1 and the stabilizing member 6. Two stitching lines 15 are provided on the outer fabric piece 1 for fixing the stabilizing buckle 14. The stabilizing buckle 14 can be used to reinforce the first loop hole 10, prevent the first loop hole 10 from being worn and torn due to continuous pulling and pressing during use, and can also facilitate the alignment between the first loop hole 10 and the second loop hole 13, that is, it plays a positioning role in the installation of the stabilizing member 6.
