Reinforcement structure to prevent button from falling off

Abstract

The reinforcing structure for preventing the button from falling off comprises a mounting layer clamped between a female button and a male button, the male button is fixedly connected with the female button through a mounting hole on the mounting layer, and further comprises non-continuous reinforcing stitches, the reinforcing stitches are discontinuous in the circumferential direction of the mounting hole; the number of the reinforcing stitches is at least one, reinforcing threads are arranged between the upper surface and the lower surface of the mounting layer to form the reinforcing stitches; the reinforcing stitches fall into the overlapping area of the orthographic projection of the female button and the male button, and the reinforcing stitches are discontinuous with the mounting hole. The reinforcing stitches assist in positioning the fabric near the mounting hole, are not easy to twist, and effectively restrict the further expansion of the crack; the non-continuous design of the reinforcing stitches forms an open area in the circumferential direction of the mounting hole, provides a stress buffering function, and avoids that the mounting layer generates a too large crack due to the tension in the button assembly process.

Description

Technical Field

[0001] This utility model patent relates to the technical field of snap fastener installation, and in particular to a reinforcement structure to prevent snap fasteners from falling off. Background Technology

[0002] Snap fasteners, commonly known as four-piece snap fasteners or spring snaps, consist of four parts: A, B, C, and D. Typically, parts A and B are clamped together to form the first snap body, and parts C and D are clamped together to form the second snap body. The first and second snap bodies are pressed together to secure them, achieving the connection function. The male snaps (parts A and D, also called the face and bottom parts) each have protrusions for passing through mounting holes.

[0003] The snap assembly process generates significant impact, which poses a risk of fabric twisting and tearing. This can result in insufficient fit between the AB and CD parts. During mass production, cracks in the mounting layer caused by tearing can easily expand due to uneven stress, ultimately causing the snaps to break off or loosen during use, leading to a poor consumer experience.

[0004] Existing snap-button reinforcement devices improve the flatness of the mounting position and enhance the overall impact resistance of the mounting layer by sandwiching an inner lining or padding material between the outer and inner layers of the bulk fabric. However, due to the uneven thickness of the outer and inner layers, the lining edge is easily visible on the outer layer, especially for thin garments, affecting the overall design. Furthermore, the lack of restraint on cracks in the outer layer means that tears created during snap-button assembly can easily expand further during wear. Utility Model Content

[0005] The purpose of this utility model is to solve the existing technical problems by proposing a reinforced structure to prevent snaps from falling off.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a reinforcing structure to prevent snaps from falling off, comprising an installation layer sandwiched between the female snap and the male snap, wherein the male snap passes through an installation hole on the installation layer and is fixedly connected to the female snap, and further comprising a reinforcing stitch that is not connected end to end, wherein the reinforcing stitch has a break in the outer circumferential direction of the installation hole; the number of reinforcing stitches is at least one, and the reinforcing thread passes between the upper and lower surfaces of the installation layer to form the reinforcing stitch; the reinforcing stitch falls within the overlapping area of ​​the orthographic projection of the female snap and the male snap, and the reinforcing stitch is not connected to the installation hole.

[0007] Preferably, the mounting layer includes a low-elasticity fabric sheet and a water-soluble liner, with the water-soluble liner covering the upper and / or lower surface of the low-elasticity fabric sheet.

[0008] Preferably, the number of reinforcing stitches is one, and the reinforcing stitches are ring-shaped or square with breaks.

[0009] Preferably, the central angle of the fracture is not less than 10°.

[0010] Preferably, the number of reinforcing stitches is 3-6, and the reinforcing stitches coincide with the radial lines of the center of the mounting hole.

[0011] Preferably, the water-soluble lining is a water-soluble film or water-soluble cloth, and the width of the water-soluble lining is greater than the width of the male or female fastener.

[0012] The beneficial effects of this utility model are: the reinforced stitching assists in the positioning of the fabric near the mounting hole, making it less prone to twisting, while effectively restraining the further expansion of the tear; the design of the ends not being connected allows the fixing stitching to form an open area around the mounting hole, providing stress buffering function and preventing the mounting layer from having excessive tears due to tension during the snap assembly process; the water-soluble lining provides pressure buffering for the low-elasticity garment piece during the snap assembly stage, reducing the occurrence of twisting and tearing of the low-elasticity garment piece; after assembly, only the water-soluble lining needs to be washed off to reveal the design of the bulk surface layer.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combined with Examples 1-3 and Appendix Figure 1-3 The reinforcement structure to prevent snaps from falling off includes an installation layer sandwiched between the female snap 12 and the male snap 11. The male snap 11 passes through the installation hole 20 on the installation layer and is fixedly connected to the female snap 12. It also includes a reinforcement stitch 4 that is not connected end to end. The reinforcement stitch 4 has a break 40 in the outer peripheral direction of the installation hole 20. There is at least one reinforcement stitch 4. The reinforcement line 30 passes between the upper and lower surfaces of the installation layer to form the reinforcement stitch 4. The reinforcement stitch 4 falls within the overlapping area of ​​the orthographic projection of the female snap 11 and the male snap 12, and the reinforcement stitch 4 is not connected to the installation hole 20.

[0018] Furthermore, the mounting layer includes a low-elasticity fabric piece 21 and a water-soluble lining 22, with the water-soluble lining 22 covering the upper and / or lower surface of the low-elasticity fabric piece 21. The water-soluble lining is a water-soluble film or water-soluble fabric, or it can be water-soluble paper. The width of the water-soluble lining is greater than the width of the male or female snap fastener. After the bulk production is assembled using snap fasteners, the water-soluble lining can be removed by washing. The water-soluble lining covering the outside of the (bulk production) avoids the problem of the inner lining and padding material edges easily protruding on the surface of existing mounting layers. The low-elasticity fabric piece can be cut and shaped from woven, cotton-linen, or leather fabrics.

[0019] Furthermore, the low-elasticity garment piece includes an overlapping outer garment piece and an inner garment piece.

There are 3-6 reinforcement stitches 4, and the reinforcement stitches 4 coincide with the radial lines radiating from the center of the mounting hole 20. There is a fan-shaped break with equal or unequal arc spacing between adjacent reinforcement stitches 4, and the central angle of the fan-shaped break is 30-180°.

[0026] Example 3
