Description

Technical Field

[0001] This utility model relates to the technical field of shoe decorative accessories, and in particular to a bending and shaping structure. Background Technology

[0002] In footwear design, especially casual and athletic shoes, the heel tab (also known as a "pulling loop") is a common functional and decorative component. In some classic shoe models, its initial function was to cover and secure the heel strap, facilitating on and off the foot and enhancing the overall look. However, with the evolution of shoe designs and changing trends, the functionality of the heel tab has gradually diminished, while its decorative and logo-displaying role has become increasingly prominent, making it an important visual element showcasing brand characteristics and design style.

[0003] Currently, the vast majority of shoes on the market with heel tongues have tongues that naturally curve outwards or stand upright. This design originates from the original structural need to secure the straps, but in today's primarily decorative market, it has significant shortcomings. First, the curved tongue completely or partially obscures the brand logo usually printed on the inside, preventing this important brand element from being effectively displayed and diminishing its decorative value. Second, the upright tongue, especially when paired with certain types of trousers such as joggers or skinny jeans, creates unnecessary interference and friction with the trouser hem, preventing the hem from hanging down naturally and affecting both aesthetics and wearing comfort.

[0004] To address the aforementioned issues, existing technologies lack effective and practical solutions. Some users attempt to shape the tongue by manually bending and pressing it for an extended period, but this method is short-lived due to the lack of internal support, and the tongue easily returns to its original shape. A few solutions consider using additional fasteners (such as stitching, snaps, or external clips), but these methods often cause permanent damage to the shoe upper fabric (such as pinholes), compromising the shoe's integrity and aesthetics, or adding a foreign object feel, significantly degrading the user's wearing experience. Therefore, the industry urgently needs an innovative built-in structure that can achieve stable and reliable bending and shaping of the heel tongue without compromising the shoe's appearance or wearing comfort. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a bending and shaping structure, which includes a first sheet-like body and a shaping member fixed on the first sheet-like body; wherein, the shaping member extends along the bending direction of the first sheet-like body, or, when the first sheet-like body is bent by an external force, the shaping member can bend along with the first sheet-like body and maintain the bent state.

[0006] The purpose of this design is to fix the bending and shaping structure to the tongue at the heel using adhesive or other methods during use. In one scenario, the shaping component in its bent and extended state allows the first sheet to be bent, thus enabling the tongue connected to it to bend. In another scenario, the shaping component follows the state of the first sheet; that is, when an external force is applied to bend and shape the tongue and the first sheet as a whole, the shaping component bends along with it and maintains its shaped state, achieving the bending effect.

[0007] In addition, this bending and shaping structure can also be used alone as a tongue or pull tab to fix the heel of the shoe, so that the tongue itself can achieve a bending effect.

[0008] The advantage of this setup is that:

[0009] First, this structure achieves stable shaping. In the first scenario mentioned above, the shaping element extends along a predetermined bending direction and is typically made of malleable metal wire, shape memory alloy strips, or high-yield-strength polymer strips. It provides sufficient anti-rebound torque to firmly maintain the bending angle, thereby overcoming the inherent elastic recovery problem of the tongue. In the other scenario mentioned above, the shaping element can follow the bending state of the first sheet-like body. It is typically made of materials such as iron wire, galvanized iron wire, stainless steel, or malleable plastics (polymers such as polyethylene or polypropylene). When an external force is applied to bend it, the inherent plasticity of the shaping element can maintain the bending state.

[0010] Secondly, this structure maintains the integrity and aesthetics of the shoe. Specifically, it is fixed to the inside of the tongue using adhesive or other methods, making it a completely non-invasive addition. The entire structure is hidden under the tongue and is not visible from any external viewpoint of the shoe. It does not damage the upper material, nor does it add any obtrusive extra parts, thus preserving the original design aesthetic value and integrity of the shoe.

[0011] Furthermore, this structure maintains a high level of comfort. Specifically, due to the combination of a flexible sheet and thin shaping components, the overall thickness is strictly controlled, resulting in a soft texture. Once fitted to the inside of the tongue, its presence is minimal, ensuring that users experience no discomfort, friction, or other foreign object sensations when wearing the shoes, walking, or exercising, guaranteeing a wearing experience indistinguishable from the original shoe.

[0012] In some examples of this utility model, the shaping component and the first sheet body are connected by one or more of the following methods: adhesive bonding, sewing, welding, and weaving.

[0013] The advantages of this design are as follows: Firstly, the use of adhesives, stitching, welding, and weaving to connect the two components ensures strong bonding between the shaping component and the first sheet. Secondly, this integrated structural design avoids problems such as internal detachment, displacement, or abnormal noise caused by bending during use, ensuring long-term stability of the bending shaping effect and product lifespan. Thirdly, multiple connection methods provide high flexibility for product design. Specifically, weaving allows the shaping component to be directly integrated into the fabric, achieving extreme thinness and flexibility; welding (such as hot-melt welding) is suitable for polymer materials and can achieve efficient sealing connections; and stitching is perfectly compatible with traditional shoemaking processes, facilitating direct integration on the production line.

[0014] In some examples of this utility model, the bending and shaping structure further includes a second sheet disposed on the side of the shaping member away from the first sheet, the second sheet being used to press the shaping member onto the first sheet.

[0015] The advantage of this setup is that:

[0016] First, the second sheet acts as a protective layer, preventing the shaping components (especially potentially sharp edges such as broken metal wires) from directly contacting the shoe tongue fabric during the adhesion process. This eliminates potential safety hazards.

[0017] Secondly, the two sheet-like bodies tightly press and fix the shaping part on its predetermined path and position. The first and second sheet-like bodies can provide a larger effective bonding area, effectively preventing the shaping part from loosening, shifting or twisting inside due to bending during use.

[0018] In some examples of this utility model, the second sheet body is connected to the first sheet body by one or more of the following methods: adhesive bonding, sewing, welding, and weaving.

[0019] The advantage of this setup is that by using adhesives, welding, or other methods, the edges of the first and second sheet-like bodies can form a continuous seal, thus encapsulating the shaping component and ensuring that the two sheet-like bodies and the internal shaping component deform together to form a whole.

[0020] When the sheet material is textile, sewing or gluing is the best option, as it is compatible with traditional shoe material processes.

[0021] When the sheet is a polymer film such as thermoplastic polyurethane (TPU) or polyethylene (PE), hot pressing or ultrasonic welding can be used to form a high-strength, seamless sealing edge.

[0022] Weaving allows all structures to be molded in one piece during the early stages of manufacturing, achieving high production efficiency and structural consistency.

[0023] In some examples of this utility model, the shaping component is made of one or more of the following: metal, plastic, malleable metal, shape memory alloy, and high yield strength polymer. The shaping component is one or more of the following: sheet, spaced sheet, spaced filament, curved filament, and woven filament.

[0024] The advantages of this design are: diverse materials and form designs provide multiple options for market positioning. For example, plastics or high-yield-strength polymers are inexpensive, corrosion-resistant, and easy to process, making them suitable for the mass consumer market; malleable metals (such as aluminum and mild steel) offer excellent shaping strength and durability, offering high cost-effectiveness. Furthermore, sheet-like materials provide uniform and strong support and anti-rebound force, suitable for scenarios requiring significant and strong fixed shaping. The spaced sheet-like or filamentous materials are an innovative design of this application, providing discontinuous support, reducing material usage, achieving lightweighting, and the entire structure has excellent lateral flexibility, making it easier to conform to the curves of the shoe tongue and avoiding stiffness; curved or woven filaments can better adapt to complex stress distributions, providing more natural and ergonomic bending curves.

[0025] In some examples of this utility model, a coating layer is provided on the shaped part made of any one of metal, malleable metal, and shape memory alloy.

[0026] The advantages of this design are as follows: First, the coating layer (such as polymer coatings: PVC, PE, epoxy resin, etc.) forms a dense physical barrier, preventing strength reduction and fracture failure caused by metal corrosion. Second, there are significant differences in hardness, surface friction coefficient, and elastic modulus between the metal material and the materials of the first / second sheet. Under the dynamic load of repeated bending, the hard metal edge is prone to wear, cutting, or even puncturing the surrounding material. The coating layer, as a soft buffer interface and transition layer, effectively absorbs stress, reduces hard friction, and protects the sheet from damage.

[0027] In some examples of this invention, the first sheet is made of fabric or leather.

[0028] The advantage of this design is that the fabric or leather and the tongue material belong to the same broad category, making them compatible. When using high-adhesion professional shoe adhesive, an extremely strong bonding interface can be formed between the fabric / leather and the fabric / leather of the tongue. Furthermore, the fabric or leather can be selected to closely resemble the original tongue in color, texture, and thickness. Once this structure is glued to the inside of the tongue, its appearance is seamlessly integrated with the tongue when viewed from the outside or slightly flipped open, providing excellent concealment.

[0029] In some examples of this invention, the second sheet is made of one of fabric, plastic, or leather. Preferably, the second sheet is a lightweight fabric with a mesh.

[0030] The advantage of this design lies in the following: the use of fabrics, leathers, etc., allows for material consistency with the first sheet, while the thin, mesh-like fabric provides a strong, anchoring adhesive effect. When the adhesive is applied to the first sheet, the mesh fabric is placed on top and pressure is applied. The adhesive partially penetrates through the mesh openings. After curing, these penetrated adhesives form numerous "micro-anchor points" or "glue nails," mechanically locking the second sheet to the first sheet. This three-dimensional bonding strength is far higher than traditional surface-to-surface bonding, greatly enhancing interlayer adhesion and effectively preventing delamination and displacement of the shaping component under repeated bending stress. Correspondingly, when this bending and shaping structure is bonded to the heel tongue, the second sheet is placed between the first sheet and the tongue. The adhesive can also penetrate the mesh openings, mechanically locking the second sheet to the tongue and deepening the bond strength between the first sheet and the tongue.

[0031] In some examples of this invention, the first sheet body forms a U-shaped groove by recessing the edge of the part to be bent toward its center.

[0032] The advantage of this design is that the U-shaped groove structurally creates a pre-defined, weaker area with lower strength, precisely defining the location where bending occurs. Furthermore, without the U-shaped groove, stress concentrates at the outermost edge of the crease during bending. The arc-shaped concave design of the U-shaped groove effectively disperses this concentrated stress across the entire arc surface of the groove, preventing excessive stress concentration at a single point that could lead to premature tearing or plastic deformation of the material, thus significantly extending the product's lifespan.

[0033] In some examples of this invention, the edge of the first sheet protrudes laterally away from its center to form a protrusion.

[0034] The advantage of this design is that the protrusions act as physical positioning blocks. During installation, the user ensures that the protrusions do not extend beyond the edge of the shoe tongue, thus guaranteeing the entire bending and shaping structure is in the correct position. Furthermore, positioning via the protrusions absolutely ensures that the auxiliary structure is completely encased in the back of the shoe tongue, with no part of it protruding from the side or bottom edge of the tongue. This achieves an "invisible" installation.

[0035] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0057] The following is for reference. Figures 1-5 The description shown is of the bending and shaping structure provided in Embodiment 1 of this utility model.

[0058] Specifically, please see the appendix. Figure 1 ~Attached Figure 3 , attached Figure 1 This is a front view of the bent and shaped structure, with attached... Figure 2 This is a rear view of the bent and shaped structure, attached. Figure 3 This is a front view of the shaping component; the bending shaping structure includes a first sheet 1a, which is made of leather and is consistent with most footwear materials. The first sheet 1a is preferably made of split leather, because both sides of the split leather are suede. One side of the suede can maintain material consistency with the tongue or zipper of the shoe itself, while the other side of the suede has good adhesive properties and can be fixedly connected to the second sheet 2a by adhesive.

[0059] The second piece 2a is glued to one side of the first piece 1a, and the edges of the second piece 2a are all covered by the first piece 1a. In other words, the edges of the first piece 1a extend beyond the edges of the second piece 2a. This is because the side of the first piece 1a with the second piece 2a needs to be glued to the tongue or zipper of the shoe. The second piece 2a is hidden inside the first piece 1a and the tongue, which maintains the uniformity of the shoe's style. The part of the first piece 1a not covered by the second piece 2a is in direct contact and glued to the tongue, which increases the bonding strength between the first piece 1a and the tongue. In addition, at the glued edge, there is only the first piece 1a as a single layer, without the second piece 2a superimposed as a second layer. Therefore, during subsequent long-term use, the adhesive force does not have to overcome the stress and tension caused by the multi-layer structure, thus maintaining a longer service life.

[0060] The second sheet 2a is specifically made of a padding lining, which is a non-woven fabric. It is lightweight and has permeability. This lining hardly increases the thickness of the bending and shaping structure. It has good and stable adhesive properties with the material of the second sheet 2a. When the two are glued together, the shaping part 3a can be pressed between the first sheet 1a and the second sheet 2a, thereby fixing the shaping part 3a to the first sheet 1a in this way. The permeability of the second sheet 2a also allows the glue between the second sheet 2a and the tongue to penetrate into the first sheet 1a, thereby ensuring the bonding strength between the first sheet 1a and the tongue.

[0061] Please see the appendix Figure 3 ~Attached Figure 4 , attached Figure 4 This is a perspective view of the various components of the bending and shaping structure. The shaping component 3a includes several spaced metal wires 31a (attached). Figure 3 (As shown by the dashed line in the middle), the metal wire 31a is preferably aluminum wire or galvanized iron wire, because the metal wire 31a needs to have sufficient fatigue resistance, will not break after a certain number of bends, and will not be corroded. Each metal wire 31a extends along the longitudinal direction of the first sheet 1a. When an external force is applied to the bending and shaping structure, the first sheet 1a is bent from the middle, and the metal wire 31a is also bent from the middle.

[0062] Ideally, the second sheet 2a needs to cover the end of each metal wire 31a. The metal wire 31a is completely wrapped between the first sheet 1a and the second sheet 2a by adhesive. This can prevent the end of the metal wire 31a from generating stress on the second sheet 2a during multiple bending processes, which would cause the edge of the second sheet 2a to curl up.

[0063] However, in this embodiment, the end of the metal wire 31a extends exactly to the end of the second sheet 2a, flush with it. This is for production considerations. Specifically, in the production process of this embodiment, sufficiently long shaping parts 3a can be arranged and fixed on the second sheet 2a first, and then the shapes of the second sheet 2a can be cut out in batches. This eliminates the need to first cut out the shape of the second sheet 2a and then glue the shaping parts 3a of a certain length and a certain spacing one by one onto the second sheet 2a, thus reducing the number of process steps.

[0064] Please see the appendix Figure 2 and attached Figure 4 As mentioned above, the edges of the first sheet 1a extend beyond the edges of the second sheet 2a. Furthermore, the longitudinal misalignment distance D between the second sheet 2a and the first sheet 1a is greater than their transverse misalignment distance d. This is to prevent the stress generated at the end of the shaping part 3a during bending from acting on the longitudinal edge of the first sheet 1a, thus reserving a sufficiently large area at the edge of the first sheet 1a for connection with the tongue, thereby coping with the stress generated at the end of the shaping part 3a. Meanwhile, the area of ​​the second sheet 2a in the transverse extension direction should be increased as much as possible to provide the shaping part 3a with the greatest possible pressing force.

[0065] Please continue reading the appendix. Figure 3 ~Attached Figure 4 The shaping component 3a also includes a covering layer 32a, which covers each metal wire 31a in a corresponding manner. The covering layer 32a is made of polyester fiber, is flat, and has anti-mildew and anti-corrosion properties. The covering layer 32a serves two purposes: firstly, to wrap the metal wire 31a inside to avoid the metal wire 31a being directly exposed and thus avoiding the risk of scratching; secondly, the flat covering layer 32a increases the area of ​​the shaping component 3a, which helps to achieve the shaping state.

[0066] Please continue reading the appendix. Figure 2 and attached Figure 4 A marking line 11a is provided on the side of the first sheet 1a facing the second sheet 2a. The marking line 11a forms inward along the edge of the first sheet 1a. This is to facilitate the bonding of the bending and shaping structure to the tongue. That is, the glue is applied to the area within the marking line 11a. During the bonding process, the glue will penetrate to the edge of the first sheet 1a, which can prevent excessive glue from leaking outside the bending and shaping structure. After bonding, a bending force is applied to the tongue, which allows the bending and shaping structure to follow the tongue to form as shown. Figure 5 The bending state shown can be maintained by the shaping part 3a.

[0067] Please continue reading the appendix. Figure 1 Appendix Figure 4 The first sheet 1a is recessed at the edge of the part to be bent, forming a U-shaped groove 12a. The U-shaped groove 12a corresponds to the upper edge of the heel, which is used to reduce the stress of the heel on the bending and shaping structure.

[0068] Please continue reading the appendix. Figure 1 Appendix Figure 4 The edge of the first sheet 1a protrudes in a direction away from its center to form a protrusion 13a. There are three protrusions 13a, which are distributed along the edge of the first sheet 1a and are mainly distributed on the upper edge of the first sheet 1a. This is to ensure that the entire bending and shaping structure is in the correct position, that is, during installation, the protrusions 13a should not exceed the edge of the shoe tongue.

[0069] The following is for reference. Figures 6-8 The diagram illustrates the bending and shaping structure provided in Embodiment 2 of this utility model.

[0070] Please see the appendix Figure 6 ~Attached Figure 8 , attached Figure 6 This is a front view of the bent and shaped structure, with attached... Figure 7 This is a rear view of the bent and shaped structure, attached. Figure 8 This is a front view of the shaping component; the bending shaping structure includes a first sheet 1b, on which a marking line 11b, a U-shaped groove 12b, and a protrusion 13b are provided; it also includes a second sheet 2b and a shaping component 3b, which includes a metal wire 31b and a covering layer 32b.

[0071] The difference between Embodiment 2 and Embodiment 1 lies in the second sheet 2b. The second sheet 2b is made of the same material as the first sheet 1b and is connected to the first sheet 1b by sewing. The first sheet 1b and the second sheet 2b are sewn together to form several cloth bags, and the shaping parts 3b are placed in the several cloth bags one by one.

[0072] The following is for reference. Figures 9-10 The description shown is of the bending and shaping structure provided in Embodiment 3 of this utility model.

[0073] Please see the appendix Figure 9 ~Attached Figure 10 , attached Figure 9 This is a front view of the bent and shaped structure, with attached... Figure 10 This is a rear view of the bending and shaping structure; the bending and shaping structure includes a first sheet 1c, on which a marking line 11c, a U-shaped groove 12c, and a protrusion 13c are provided; it also includes a shaping component 3c, which is a metal wire 31c, which is made of pure metal or formed by winding metal wire and other filamentous materials.

[0074] The difference between this embodiment 3 and embodiment 1 is that there is no second sheet, and the metal wire 31c is sewn onto the first sheet 1c.

[0075] Please see the appendix Figure 11 The image shows a side view of the shaping component in some embodiments. In some embodiments, the shaping component 3d is bent and extended along the bending direction. After the bent shaping structure is installed on the tongue, it can present a bending effect. The shaping component 3d is made of materials such as plastic, malleable metal, shape memory alloy, and high yield strength polymer, and has the ability to recover deformation and maintain the predetermined bending shape.

[0076] Please see the appendix Figure 12 The image shown is a front view of the shaping element in some other embodiments. In some embodiments, the shaping element 3e is a curved filament, which may also be provided with a covering layer.

[0077] Please see the appendix Figure 13 The image shown is a front view of the shaping element in some other embodiments. In some embodiments, the shaping element 3f is a woven filament, which may also be provided with a covering layer.
