Description

Technical Field

[0005] , ,

[0001] This application claims the priority of a Chinese patent application filed with the China National Intellectual Property Administration on May 14, 2024, with an application number of 202421054138.5 and a utility model title of "Ultra-thin Snap Button", and all its contents are incorporated herein by reference.

[0002] This utility model belongs to the technical field of buttons, and particularly relates to an ultra-thin snap button.

Background Art

[0003] Snap buttons belong to ordinary fasteners and are called snap fasteners. Generally, they include female snaps and male snaps, and are widely used in products such as clothing, bags, umbrellas, etc. There is a locking groove at the center of the female snap for fastening and locking with the snap beads. In order to improve the elastic fastening force in the locking groove, generally, an elastic component is installed. There is a protruding snap bead at the center of the male snap. The female snap and the male snap are respectively attached to different fabrics. When the female snap and the male snap fit together, the snap bead of the male snap clamps the two together by the elastic force of the elastic component in the locking groove of the female snap, realizing the close adhesion of the two fabrics connected by the male snap and the female snap.

[0004] Currently, the thickness after the male snap and the female snap of the conventional snap button are fitted is too thick. For most products such as clothing, snap buttons with a large bottom material thickness result in insufficient adhesion between the two fabrics, generating a large gap, which affects the appearance and usage experience of the product.

Modes for Carrying Out the Invention

[0020] The embodiments of the present utility model will be described in detail below. An example of the above embodiments is shown in the drawings, and the same or similar reference numerals always represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are only for the purpose of interpreting the present utility model and should not be construed as limiting the present utility model.

[0021] The core of the present utility model is to provide an ultra-thin snap button that can effectively avoid the problem that the thickness of the bottom member is too thick.

[0022] In order for those skilled in the art to better understand the technical solutions provided by the present utility model, the following will combine the drawings and specific embodiments to explain the present utility model in detail.

[0023] Specifically, referring to FIGS. 1 to 8, the ultra-thin snap button provided by the present utility model includes a female snap unit 1 including a first snap surface 11 and a slingshot cup 12.

[0024] The first snap surface 11 has a first cavity and a first opening is provided. A first tapered gasket 112 and a first snap surface gasket 111 are installed in the first cavity of the first snap surface 11. The first snap surface gasket 111 is covered by the first tapered gasket 112 and forms a second cavity. A second opening is opened in the first snap surface gasket 111, and the tapered surface of the first tapered gasket 112 faces the second opening and the first opening. The first tapered gasket 112 has a tapered surface protruding outward. The first snap surface gasket 111 is a bending plate, and the shape of the bending plate can be adaptively improved according to the shapes of the first tapered gasket 112 and the inner wall of the first cavity of the first snap surface 11. The first tapered gasket 112 is restricted within the first snap surface 11 by the first snap surface gasket 111, and a second opening is opened in the first snap surface gasket 111, as long as the second opening can face the first opening and the tapered surface of the first tapered gasket 112.

[0025] The slingshot cup 12 has a first mounting post 121 on its upper surface and a third opening on its lower surface for engaging with the male snap unit 2. The first mounting post 121 can be inserted into the second opening of the first snap surface gasket 111 through the first opening of the first snap surface 11, and when pressed, the first mounting post 121 bends outward due to the guiding action of the tapered surface of the first tapered gasket 112, forming a first burring inside the second cavity.

[0026] When assembled, the first snap surface 11 is located on one side of the first fabric, and the slingshot cup 12 is located on the other side of the first fabric. The first mounting post 121 of the slingshot cup 12 can penetrate the first fabric and be press-fitted into the first tapered gasket 112. The first mounting post 121 forms a first burring in the second cavity, and the first burring is locked into the first snap surface gasket 111, thereby securing the first snap surface 11 and the slingshot cup 12 to the first fabric.

[0027] Conventional snap buttons have a mounting post on the snap surface and a tapered gasket inside the slingshot cup 12. When assembled, the mounting post bends outward into the slingshot cup 12, which compresses the space inside the slingshot cup 12 and makes the snap too thick. Snap buttons are often installed on the front placket of clothing, and a thick bottom component prevents the garment from fitting snugly after assembly, resulting in a slight gap in the front placket of the garment. This affects the quality and user experience of the product, as well as the overall aesthetic appearance of the garment.

[0028] Unlike conventional snap buttons, the ultra-thin snap button provided by this utility model has a first mounting post 121 attached to the slingshot cup 12, and a second cavity for forming the first burring of the first mounting post 121 is installed within the first snap surface 11 by a reverse connection method between the first snap surface 11 and the slingshot cup 12. This reduces the thickness of the slingshot cup 12 as a base member, effectively avoiding the problem of the base member being too thick.

[0029] In a specific embodiment, the slingshot cup 12 has an annular third cavity, the upper part of which communicates with the upper environment via the first mounting post 121, and the lower part of which communicates with the lower environment via the third opening. A protective gasket 123 is installed inside the third cavity and is used to shield the first mounting post 121 from the third opening.

[0030] Adding a protective gasket 123 to the slingshot cup 12 prevents the structure of the first mounting post 121, which may bend outward during use of the ultra-thin snap button, from being visible from the third opening, providing a more overall visual experience for the user. Furthermore, it protects the bead head of the snap bead 22 from being damaged during use, improving the aesthetic appearance of the garment and fastener.

[0031] To improve the fastening of the connection between the slingshot cup 12 and the snap bead 22 in the male snap unit 2, an elastic washer 122 is installed in the third cavity, and the elastic washer 122 provides pressing force to the snap bead 22 in the radial direction. By retaining the elastic member inside the conventional snap, the problem of the snap being too thick in the prior art is solved, and the mating force of the product is ensured not to change due to the structural modification.

[0032] As shown in Figure 5, the slingshot cup 12 has an annular structure, and the cross-section of the annular structure is U-shaped with the opening facing the axis, and the U-shaped groove formed by the annular mechanism is the third cavity. The first mounting post 121 includes a tubular structure and a bent plate connected to one end of the tubular structure, the bent plate being stepped, and the bent plate is used so that its upper surface is in close contact with the inner wall of the slingshot cup 12 and its lower surface abuts against the protective gasket 123. The protective gasket 123 is a stepped bent plate, and the protective gasket 123 is used so that its highest horizontal plane can shield the first mounting post 121, specifically so that it can abut against the bent plate portion of the first mounting post 121. The protective gasket 123 has both sides of its lowest vertical plane abutting against the inner wall of the slingshot cup 12 and the outer wall of the elastic washer 122, respectively. On the one hand, the position of the elastic washer 122 can be limited and prevented from swinging, and on the other hand, the first mounting post 121 can be shielded so that the first burring of the first mounting post 121 is not visible from the third opening.

[0033] Of course, at least two of the first mounting post 121, slingshot cup 12, and protective gasket 123 are either integrated or separate components. At least two of the first snap face 11, first tapered gasket 112, and first snap face gasket 111 are either integrated or separate components. Adopting an integrated structure makes it convenient to simplify the product, while adopting a separate structure allows the whole to be formed by combining and mounting them, and specifically, it can be adaptively selected according to the actual application scene.

[0034] This solution further includes a male snap unit 2 for locking onto a female snap unit 1, the male snap unit 2 being installed on a second fabric. The female snap unit 1 and the male snap unit 2 are each installed on different fabrics.

[0035] The male snap unit 2 includes a second snap surface 21 and a snap bead 22, and a second mounting post 211 is installed on the second snap surface 21.

[0036] The snap bead 22 consists of a locking post 221, a second tapered gasket 222, and a second snap surface. Gasket 223 The locking post 221 includes a protrusion on one side for engaging with the third opening of the female snap unit 1, and a fourth cavity on the other side for attaching the second tapered gasket 222, and the second snap surface Gasket 223 It is covered by the second tapered gasket 222 and forms a fifth cavity, and the second snap surface Gasket 223 A fourth opening is provided, and the tapered surface of the second tapered gasket 222 faces the fourth opening.

[0037] When assembled, the second snap surface 21 is located on one side of the second fabric, the snap bead 22 is located on the other side of the second fabric, the second mounting post 211 on the second snap surface 21 can penetrate the second fabric and be press-fitted into the second tapered gasket 222, the second mounting post 211 forms a second burring in the fifth cavity, and the second burring is on the second snap surface Gasket 223 It is secured to the second snap surface 21 and snap bead 22, fixing them to the second fabric.

[0038] In specific embodiments, the second snap surface 21 and the second mounting post 211 are either an integrated structure or separate structures. The locking post 221, the second tapered gasket 222, and the second snap surface Gasket 223 At least two of these structures are either integrated or separate. While an integrated structure allows for convenient product simplification, a separate structure allows for the entire product to be formed by combining and attaching components, and specifically, the choice can be adaptively made depending on the actual application scenario.

[0039] As shown by combining Figures 7 and 8, the process of attaching the first snap surface 11 and the slingshot cup 12 is as follows: a hole is made in the first fabric, the first mounting post 121 is aligned with the first tapered gasket 112 on the first snap surface 11 at the hole position, the first snap surface 11 is struck, the first mounting post 121 is pressed and deformed, the edge of the first mounting post 121 curls up and generates a first burring, the first burring is locked into a second cavity formed between the first snap surface gasket 111 and the first tapered gasket 112, thereby forming the female snap unit 1, and at the same time the first snap surface 11 and the slingshot cup 12 are clamped to the first fabric. The process of attaching the second snap surface 21 and snap bead 22 is as follows: a hole is made in the second fabric, the second mounting post 211 is aligned with the second tapered gasket 222 on the snap bead 22 at the hole position, the second snap surface 21 is struck, the second mounting post 211 is pressed and deformed, the edge of the second mounting post 211 is curled up and a second burring occurs, and the second burring is attached to the second snap surface Gasket 223 The male snap unit 2 is formed by engaging with the fifth cavity formed between the second tapered gasket 222, and at the same time the second snap surface 21 and snap bead 22 are clamped to the second fabric.

[0040] As shown in Figure 8, during use, the locking post 221 of the snap bead 22 passes through the third opening at the bottom of the slingshot cup 12, pressing and deforming the elastic washer 122 inside the slingshot cup 12, thereby effectively engaging the snap bead 22 with the slingshot cup 12, and thereby enabling the release or engagement of the female snap unit 1 and the male snap unit 2 in the snap.
