Description

Technical Field

[0001] This utility model relates to the field of footwear component structure, and in particular to the heel counter. Background Technology

[0002] To facilitate easy tightening and loosening of shoelaces when putting on and taking off shoes, existing footwear products have improved shoelace tightening by using a quick-tightening shoelace device. In addition to the common location on the instep, this device can also be located on the heel, such as on the heel of the shoe upper (this adjustment is usually achieved by manually rotating to tighten or by pressing and pulling to loosen) or on the rear side of the heel on the sole (this adjustment is usually achieved by foot movements, using the forefoot to lift, the heel to press down and slide forward and backward or backward and forward to tighten, and changing the state of the heel to loosen).

[0003] The aforementioned device is located at the heel, with shoelaces extending from the instep area of ​​the shoe upper to the heel area and threaded through a pre-fabricated cavity within the upper. The tension of the upper is quickly adjusted by controlling the linear displacement of the shoelaces within the cavity using an adjustment mechanism. While this design improves operational efficiency, it presents several problems in practical use: 1. Shoelace misalignment due to dynamic deformation: During wear, the upper undergoes continuous multi-directional deformation (bending, twisting, stretching) due to foot movement, and a gap must be maintained between the cavity and the shoelaces to ensure smooth sliding. 1. When the deformation of the upper exceeds the design threshold, the shoelaces are prone to unexpected displacement (misalignment) within the interlayer, causing them to deviate from the preset movement trajectory; 2. Systemic failures caused by traction transmission deviation: When the misaligned shoelaces are transmitted to the heel adjustment mechanism, two failure modes occur due to path inaccuracy. One is misalignment and jamming, where the shoelaces and the transmission wheel / locking teeth of the adjustment mechanism are misaligned, causing the mechanism to fail to lock or the adjustment resistance to increase dramatically. The other is uneven load wear, where the shoelaces continuously rub against the interlayer cavity wall or adjustment components on one side, accelerating material fatigue (such as lining tearing, rope fraying), ultimately leading to structural functional damage; 3. Decreased user experience and reliability: The above problems force users to frequently manually reset the shoelace position, losing the core advantage of "quick adjustment". At the same time, the risk of mechanism jamming or rope breakage significantly reduces the product's service life and increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a heel counter with a shoelace positioning and guiding sliding structure that can effectively solve the above-mentioned problems by limiting the position of the shoelace traction tension and sliding.

[0005] To achieve the above objectives, the technical solution of this utility model is: a heel counter with a shoelace positioning and guiding sliding structure, comprising a counter body, characterized in that the counter body is provided with a positioning and guiding structure, the positioning and guiding structure being configured to position the shoelace tension sliding path.

[0006] The positioning and guiding structure is a guiding channel formed between the inner and outer sides of the Hongbao body, and the two ends of the guiding channel are ports leading to the outside of the Hongbao body.

[0007] The positioning guide structure includes several positioning parts for shoelaces to be threaded or embedded.

[0008] The positioning part includes an inlet positioning part and an outlet positioning part. The positioning guide structure also includes a guide channel between the inlet positioning part and the outlet positioning part for the shoelace to be inserted or embedded and slid in and out.

[0009] The guide channel is a groove with an embedding opening provided on the inner side of the main body of the Hongbao, and the groove is constructed with a hook portion in the cross-section to prevent it from falling out of the groove.

[0010] The guide channel is a groove with an embedded opening provided on the outer side surface of the Hongbao body.

[0011] The groove is constructed with a hook-like structure on the cross-section to prevent it from being embedded and detached.

[0012] It also includes a guide tube connected to the main body of the heel counter via a positioning and guiding structure, which allows the shoelaces to slide and adjust within the tube; and / or, the main body of the heel counter is further provided with a corresponding device part, to which the positioning and guiding structure is correspondingly guided.

[0013] The end of the conduit extends out of the main body of the port to form a protective sleeve section.

[0014] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The above structural design, by setting a positioning and guiding structure on the heel counter, limits the position of the shoelace traction tension and slippage. Since the heel counter is mainly used to support the heel part of the shoe upper and has a certain anti-deformation and self-recovery structural function, the positioning and guiding structure set on the heel counter can effectively and reliably protect the shoelaces that slip through the heel area. The positioning and guiding structure is relatively fixed in position and structurally stable, thus effectively solving the problems of shoelace misalignment caused by dynamic deformation, systemic failures caused by traction force transmission deviation, and decreased user experience and reliability. The above-mentioned further structural design can simplify the product structure design, facilitate manufacturing and production operations, and reduce the impact on the product's structural strength and the problem of discomfort in the heel when the finished shoes are used.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] A heel counter with a shoelace positioning and guiding sliding structure, as shown in Figures 1-4, includes a heel counter body 10 that is typically arc-shaped and can correspond to and surround the heel of the human foot. The central section of the arc shape corresponds to the rear side of the heel, and the two ends of the arc shape extend towards the left and right sides of the foot. It is commonly made of plastic and / or rubber injection molding structure. Unlike existing product structures, the heel counter body 10 is provided with a positioning and guiding structure 1. The positioning and guiding structure 1 can be set in various structures, mainly to realize the function of positioning the shoelace tensioning and sliding path. Common quick shoelace tensioning devices set in the heel are mainly located on the rear side of the heel section of the upper or the rear side of the heel section of the sole. Therefore, the traction of the shoelace usually corresponds to the two ends or near the two ends of the heel counter body 10, passing through to the central section of the heel counter body 10 or to the lower edge of the central section of the heel counter body 10. The choice of structural settings on the corresponding shoes is mainly determined by the location of the quick-release sole tensioning device on the actual shoe product, the outline of the heel counter, the thickness of the shoelaces, and the introduction and exit points of the shoelace traction.

[0025] like Figure 3In the first embodiment shown, the positioning guide structure 1 is a guide channel 11 formed between the inner and outer sides of the heel counter body 10, and both ends of the guide channel 11 are ports 12 leading to the outside of the heel counter body 10. This structure makes the guide channel 11 invisible internally, and it can be an integrally formed structure during the manufacturing of the heel counter body 10. The guide channel 11 can be formed by a core-pulling process. This structure is more suitable for products with sufficient thickness in the parts on the heel counter body 10. The overall structure has high strength and allows shoelaces to be directly inserted inside. The port 12 can be inserted with an end protective sleeve for shoelaces to be inserted inside (not shown in the figure). The length of the end protective sleeve can be adapted to extend from the port 12 to the corresponding shoelace hole near the instep, which can play a role in protecting and guiding the shoelaces.

[0026] Alternatively, the positioning and guiding structure 1 can also be as follows: Figure 2 Another embodiment shown includes several positioning portions 13 for inserting or embedding shoelaces. The positioning portions 13 are arranged along the intended shoelace tensioning and sliding path, and can be located at the ends or spaced apart along the intended shoelace tensioning and sliding path. The structure of the positioning portions 13 can be a positioning lug with a through hole or a positioning lug on the backrest body 10 that is concave on one side and convex on the other side, forming a through hole. In use, the shoelaces are passed through the positioning portions 13 one by one along the tensioning and sliding path to achieve the desired tension. Figure 1 The structure effectively positions the object without affecting its sliding motion, and it also does not affect the overall structural strength of the Hongbao body 10.

[0027] Again, such as Figure 1 and Figure 4 The third embodiment shown is... Figure 2The improved structure includes an introduction positioning part 131 and an exit positioning part 132. The positioning guide structure 1 also includes a guide channel between the introduction positioning part 131 and the exit positioning part 132 for the shoelace to slide and tighten or be inserted. In this embodiment, the guide channel is different from the guide channel 11 in the first embodiment. It can be a groove with an insertion opening on the inner side of the backrest body 10 (the figure shows the structure with the groove on the inner side). The shoelace enters from the introduction positioning part 131, exits from the exit positioning part 132, and the section in between is then inserted into the groove through the insertion opening. The introduction positioning part 131 and the exit positioning part 132 act as a guide for the two ends of the groove. Due to the concave, arc-shaped inner surface of the heel counter 10, if the shoe is not prevented from slipping out of the groove, the normally traction shoelaces will tend to shift to the side of the straight traction and slip out of the groove, rendering the groove ineffective in restraining the shoe. To address this issue, this embodiment constructs the groove with a hook-like structure in its cross-section to prevent slippage. Specifically, the cross-section of the groove has a C-shaped hook arm, with the C-shaped opening serving as the insertion opening. This allows the shoelaces to be hooked in the C-shaped hook arm to prevent slippage. If the thickness of the guide channel 14 corresponding to the heel counter 10 is relatively thin, it can be increased by protruding from the outer surface of the heel counter 10 corresponding to the groove, thereby increasing the thickness of that area and improving structural strength. Additionally, if... Figure 1 and Figure 4 As shown, the guide channel 14 is a groove 141 with an embedding opening provided on the outer surface of the heel counter body 1. This outer surface is arc-shaped. After the shoelace is pulled across the outer surface and embedded in the groove 141, it will slide close to the bottom of the groove, making it less likely to come out. Therefore, compared with the inner surface, this structure can keep the inner surface of the heel counter body 1 flat, avoiding the problem of discomfort when wearing shoes and the problem of the shoelace tending to deviate from the straight pulling side and come out of the groove 141. If there is a problem of coming out, the groove 141 can be constructed with a hook-shaped structure in the cross-section to prevent it from coming out of the groove 141, achieving the same effect as above.

[0028] To protect the shoelace components and prevent wear or breakage of the shoelaces or grooves that could shorten their lifespan or cause slippage, the structural design of the above-described embodiments can be further modified. Specifically, the positioning guide structure 1 may include a conduit 2 (e.g., a guide tube 2 connected to the heel counter body 10 for the shoelaces to slide and adjust within the conduit) that allows the shoelaces to pass through and adjust their tension. Figure 1 or Figure 4(As shown in the dotted line portion), the conduit 2 can be made of a flexible and wear-resistant material. Besides protecting the shoelaces and guide channel 14, the conduit 2 also improves the smoothness of the shoelaces' movement. In use, it can be directly inserted into the guide channel 11 of the first embodiment or the upper inner positioning part 131, exit positioning part 132, groove, or groove 141 of the second or third embodiment and fixed in place. The shoelaces slide within the conduit 2, further stabilizing the structure and its function. The end of the conduit 2 can extend beyond the main body 10 to form a protective sleeve section 21. Its function is as described above; the length of the protective sleeve can be adapted to extend from the port 12 to the corresponding shoelace hole near the instep, providing both protection and guidance for the shoelaces.

[0029] Furthermore, to ensure smooth guidance of the shoelaces on the heel counter body, the present invention can also provide a corresponding device part on the heel counter body 10, as shown in the figure, which is located at the bottom of the rear side of the heel. Its structure is designed to cooperate with the quick-tightening shoelace device. The positioning guide structure 1 guides the shoelaces to the corresponding device part, thereby enabling the shoelace traction to be closer to the inlet and outlet of the quick-tightening shoelace device, making the shoelace unwinding action smoother.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
