Description

Technical Field

[0001] This utility model discloses an automatic tightening shoe, belonging to the field of footwear technology. Background Technology

[0002] Shoelaces are used to adjust the tightness of the shoe upper and ensure foot comfort. Traditionally, shoelaces are tied in a crisscross knot, which is tedious and often becomes too tight, too loose, or comes undone during walking and exercise, causing considerable inconvenience. Lace-less shoes overcome these problems. Through special design and materials, shoes can be worn without laces, maintaining both stability and comfort.

[0003] Currently, there is an automatic tightening shoe on the market with patent application number CN200880019973.2. It has a tightening device at the heel and the shoelaces are wrapped around the inside of the shoe upper and extended to the tightening device. This allows people to tighten the shoelaces by lifting their heels and rolling the tightening device, making it more convenient for people with lumbar problems to use.

[0004] However, in the aforementioned patent's tightening device, the tube used to thread the connecting rope is directly fixed inside the shoe upper, and the tube is made of a soft material, resulting in insufficient support. When the rope is tightened, the tightening force on the back of the shoe upper is concentrated on these two tubes, causing the shoe upper to not fit the wearer's heel well after tightening, affecting comfort. The concentrated tension also increases the probability of glue separation or stitching failure in these two areas. Furthermore, the insufficient support can easily lead to errors in the installation of the tubes and the installation of the upper and sole during production, resulting in frequent defective products. To solve this problem, a new solution is needed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic tightening shoe to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an automatic tightening shoe, comprising a sole and an upper, characterized in that: the upper comprises a forefoot component, a heel counter component, a tongue component, and an edge banding component; the front edge of the heel counter component is connected to the forefoot component; the edge banding component covers and fixes the top of the forefoot component and the heel counter component; the tongue component comprises a connecting portion and a tongue portion fixedly connected; the connecting portion is disposed at the edge of the tongue portion; the connecting portion is fixed to the forefoot component; the heel counter component comprises a lining piece, a backrest component, a cord tube, a drawstring, an outer fabric piece, and a buckle; the backrest component is fitted to the lining piece; the backrest component... A limiting groove for installing a rope tube is provided, the limiting groove extending from both ends of the top of the heel counter towards its bottom center. The pull rope is threaded through the rope tube. The edge of the outer fabric piece is connected to the edge of the inner fabric piece. The rope tube extends from the bottom of the heel counter to the outside of the heel counter. A groove is provided on the sole to mate with the rope tube. An installation groove communicating with the groove is provided at the heel of the sole. A tightening device is provided in the installation groove. Openings are provided at both ends of the outer fabric piece. Buckles are provided on the openings and are fixed to the outer fabric piece by two stitching lines. The pull rope extends to the outside from the buckles.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] 1. The upper is designed to consist of a forefoot component and a heel counter component. The drawstring tube is located inside the heel counter component, which also contains a backrest component. The rigidity of the backrest component provides good support for the heel counter component. The backrest component also has a limiting groove for installing the drawstring tube, so the backrest component also supports the drawstring tube. Therefore, when the drawstring is tightened, the tension will first act on the backrest component from the drawstring tube. The backrest component has a strong support effect and can disperse the force, thereby tightening the entire upper and making it fit the user's heel better. It also reduces the occurrence of glue separation and stitching due to concentrated tension.

[0009] 2. By setting a limiting groove on the back support component to install the rope tube, and combining the two inside the back support component, the back support component can support the rope tube, thereby stabilizing the rope tube during the production process, ensuring the installation position of the rope tube, and reducing the probability of skewed or defective products.

[0010] 3. By designing the upper to consist of a forefoot component, a heel counter, a tongue component, and an edge banding component, the heel counter, which has a composite and internal structure, and the forefoot component, which is simply cut, are produced separately, increasing production efficiency. Furthermore, the edges of the tongue component are fixed to the forefoot and heel counter components by gluing or sewing, so that the tongue will not retract into the shoe due to the pressure of the instep when wearing the shoes, thus further ensuring that the wearer does not need to bend over when wearing the shoes.

Detailed Implementation

[0016] 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.

[0017] A type of self-adjusting shoe, such as Figure 1 As shown, it includes a sole 1 and an upper 2, as... Figure 2 , Figure 3 As shown, the upper 2 includes a forefoot component 3, a heel counter component 4, a tongue component 5, and a edging component 6. The front edge of the heel counter component 4 is connected to the rear edge of the forefoot component 3, and the edging component 6 covers and fixes the top edges of the forefoot component 3 and the heel counter component 4 to enhance the aesthetics and comfort.

[0018] like Figure 3As shown, the shoe tongue 5 includes a connecting part 17 and a tongue part 18 that are fixed together. The connecting part 17 is located on the edge of the tongue part 18. The connecting part 17 and the tongue part 18 can be integrally cut from the same piece of fabric and then heat-pressed, or the two parts can be cut separately and then sewn together. The connecting part 17 is fixed to the inside of the forefoot part 3 and is covered by the forefoot part 3. The tongue part 18 is located at the opening of the shoe tongue at the top of the forefoot part 3 and the heel counter 4. The connecting part 17 is fixed by sewing, and the sewing line is set along the edge of the tongue part 18. Therefore, the sides and bottom of the tongue part 18 are fixed. When the wearer wears the shoe, the shoe tongue will not retract into the shoe due to the pressure of the instep when wearing the shoe, further ensuring that the wearer does not need to bend over when wearing the shoe.

[0019] like Figure 4 As shown, the back panel 4, from the inside out, includes a lining piece 7, a pull tab 8, a rope tube 9, a drawstring 10, an outer fabric piece 11, and a buckle 16. The pull tab 8 can be shaped with a pull head and is fitted to the lining piece 7. A limiting groove 12 for installing the rope tube 9 is provided on the side of the pull tab 8 away from the lining piece 7. The limiting groove 12 extends from both ends of the top of the pull tab 8 towards its bottom center. The limiting groove 12 can be set on the mold, so that it can be directly formed on the pull tab 8 after injection molding, or it can be added after the pull tab 8 is formed. Grooving offers two advantages: the former provides higher production efficiency, while the latter facilitates temporary adjustments to the shape of the limiting groove 12. The rigidity of the heel counter 8 provides good support for the back panel, and the setting of the limiting groove 12 also allows the heel counter 8 to support the rope tube 9. Therefore, when the pull rope 10 is tightened, the tension will first act on the heel counter 8 from the rope tube 9. The heel counter 8 has a strong supporting effect and can disperse the force, thereby allowing the back panel 4 to tighten as a whole, fit the user's heel better, and also reduce the occurrence of glue separation and stitching due to concentrated tension.

[0020] like Figure 2 As shown, the rope tube 9 extends from the bottom of the back panel 4 to the outside of the back panel 4. The pull rope 10 is inserted into the rope tube 9. The edge of the outer fabric piece 11 is connected to the edge of the inner fabric piece 7. The sole 1 is provided with a groove 13 that cooperates with the rope tube 9. The groove 13 can be modified according to the specific style, for example, it can be set as two round holes or as a square groove. The groove 13 can also be formed together with the sole 1 during injection molding or cut after the sole 1 is formed. The heel of the sole 1 is provided with an installation groove 14 that communicates with the groove 13. A tightening device is provided in the installation groove 14. The tightening device can be the device in the patent document with patent number CN200880019973.2 mentioned in the background art, or other existing rolling tightening device structures that use ropes for tightening. The specific structure of the tightening device is not within the scope of protection claimed in this application, but the shoe structure of this application is applied to such a shoe with a tightening device.

[0021] like Figure 3 , Figure 4 As shown, openings 15 are provided at both ends of the outer fabric piece 11, and buckles 16 are provided on the openings 15 and fixed to the outer fabric piece 11 by two stitching lines. The pull cord 10 extends to the outside from the buckle 16. The buckle 16 plays a protective role for the openings 15, enhances the strength and stability of the openings 15, prevents cracking, and also makes it easier to thread the pull cord 10.

[0022] This invention divides the shoe upper 2 into a heel counter 4 with a composite structure and internal structure, and a forefoot 3 that is simply cut, allowing the two to be produced separately and then combined, increasing production efficiency. When adjustments or modifications are needed, the structural parts inside the heel counter 4 can be modified separately before processing and forming, reducing modification costs. The installation structure and steps of the rope tube 9 inside the heel counter 4 are simple, strong and reliable, reducing the probability of defects and skew in the finished product, and making it easier to modify and design different styles and models.

[0023] The retaining part 8 is provided with a limiting groove 12 to install the rope tube 9, and the two are combined inside the back support part 4. The retaining part 8 can support the rope tube 9, thereby stabilizing the rope tube 9 during the production process, ensuring the installation position of the rope tube 9, and reducing the probability of skewed defective products.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
