Abstract
Description
Technical Field
[0001] The present invention relates to a spring snap button, and more particularly to a spring snap button which can prevent a female snap button component from sliding or shaking even when the thickness of leather or fiber fabric is relatively thin, and because the diameter of the spring component can be changed by means of elastic force, the convenience of using the spring component can be achieved regardless of the size (diameter) of a snap-on protrusion formed on a male snap button component, and can prevent leather or fiber fabric from being damaged when the female snap button component is pressurized and installed. Background Art
[0002] A snap button is a metal button that is made up of a concave surface and a convex surface in pairs. It is also called a five-claw button (pressbutton), which is the abbreviation of a snap fastener, and is also called an emergency button. Such hidden buttons are widely used in belts (including leather and fiber fabrics), bags and clothing.
[0003] Generally speaking, spring snaps are Figure 1 As shown, it is composed of a female buckle component 120 and a male buckle component 110, and a fastening protrusion 112 protruding upward from the upper part of a main body 111 is formed on the male buckle component 110, and a coupling protrusion 113 protruding downward from the lower part of the main body 111 is formed. After the coupling protrusion 113 is inserted and installed into the through hole of the product to be installed, the coupling protrusion 113 is pressurized by using a punching machine or the like, so that a part of the coupling protrusion 113 can be torn and stretched, so that it can be coupled and installed in the product.
[0004] In addition, the female buckle component 120 is composed of a first connecting component 120a and a second connecting component 120b. When the raised outer cover 122 is placed in a manner to penetrate a through hole formed on the leather or fiber fabric, the first connecting component 120a and the second connecting component 120b are placed facing each other with the through hole as the center and then press-connected using a punching machine or the like.
[0005] A protrusion insertion port 123 is formed on the protrusion outer cover 122 for inserting the fastening protrusion 112 of the male buckle component 110 , and linear springs 125 are inserted on both sides of the interior of the female buckle component 120 . A portion of the linear spring 125 is located inside the protrusion insertion port 123 through the spring insertion port 124 of the female buckle component 120 .
[0006] When the fastening protrusion 112 of the male buckle component 110 is inserted into the protrusion insertion port 123 of the female buckle component 120, the protrusion 113 of the fastening protrusion 112 will be squeezed to the outside of the spring insertion port 124 by the spring 125. Then, when the groove 114 of the fastening protrusion 112 reaches the position of the spring insertion port 124, the spring 125 will squeeze the groove 114 of the fastening protrusion 112, thereby fastening the male buckle component 110 and the female buckle component 120.
[0007] In the fastening process of the existing spring snaps with the structure as described above, the extrusion spring 125 of the female snap component 120 will re-enter the spring insertion port 124 after being detached from the spring insertion port 124 with the help of the protrusion 113 of the coupling protrusion 112 of the male snap component 110. However, in the process of re-entering the spring insertion port 124 after being detached from the spring insertion port 124, the female snap component 110 often cannot be firmly fastened because the spring 125 is stuck at the upper end of the spring insertion port 124 and cannot enter.
[0008] Moreover, because the linear spring 125 is clamped on both sides with the fastening protrusion 112 as the center, its supporting force is weak and the spring 125 is easily deformed, thereby resulting in a decrease in the bonding force, which leads to a decrease in the function of the snap button. There is also the problem that the snap button cannot be used anymore when the diameter of the fastening protrusion 112 becomes larger.
[0009] In addition, because the thickness of the raised outer cover 122 is greater than the thickness of the combined product, it is impossible to fix the thinner product and its fixing force is weakened, which causes the first combining component 120a and the second combining component 120b to slide against each other and shake, and the shaking will also cause the female buckle component 120 to separate.

[0048] Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0049] In the attached figure Figure 2 is an exploded perspective view illustrating the structure of a spring snap button to which the present invention is applicable. Figure 3 It is a cross-sectional view illustrating the structure of a spring snap according to the technology applicable to the present invention. According to the structure of the spring snap 1 of the present invention, it includes: a female snap component 10, which is fixedly mounted on leather or fiber fabric and is formed with a through hole; a male snap component 20, which is fixedly mounted on the leather or fiber fabric and is connected and separated by being inserted into the through holes 10a-1 and 10b-1 of the female snap component 10; an anti-sway component 30, which is used to prevent the female snap component 10 or the leather or fiber fabric from rolling when the female snap component 10 is installed on a leather or fiber fabric F with a thinner thickness; and a spring component 40, which is in a "C" shape and is installed in the insertion portion in a manner that can prevent it from detaching with the help of the connecting portion.
[0050] The female buckle component 10 is composed of a first coupling component 10a-2 equipped with a through hole 10a-1 and integrally formed with a coupling portion protruding to one side, and a second coupling component 10b equipped with a through hole 10b-1 and integrally formed with an insertion portion 10b-2 into which the coupling portion 10a-2 can be inserted and embedded.
[0051] Among them, the length of the insertion part 10b-2 is the minimum thickness that can pressurize the leather or fiber fabric F and fix the female buckle component 10 when the first combining component 10a and the second combining component 10b are combined. When the thickness of the leather or fiber fabric is less than the length of the insertion part 10b-2, the female buckle component 10 cannot be fixed and installed and will shake.
[0052] Therefore, when the thickness of the leather or fiber fabric is smaller than the length of the insertion portion 10b-2, when the first combining component 10a and the second combining component 10b are combined, the first combining component 10a and the second combining component 10b are combined as shown in the accompanying drawings. Figure 3 As shown in the side of the leather or fiber fabric F or as shown in the accompanying drawings Figure 6 As shown, anti-sway components 30 are installed on both sides.
[0053] The structure of the anti-sway component 30 is a structure in which a through hole 32 for the coupling protrusion 21 of the male buckle component 20 to pass through is formed on a flat anti-slip plate 31 of a certain thickness, and a plurality of spikes 33 are protruded at a certain interval on one side of the anti-slip plate 31 and fixedly installed by being inserted into leather or fiber fabric.
[0054] You can use the following figure Figure 3 The sharp burr shape formed by striking the surface of the anti-slip plate 31, or as shown in the accompanying drawings Figure 5a to Figure 5c The pointed object 33 is one of a cone, a triangular pyramid and a quadrangular pyramid formed by striking the surface of the anti-slip plate 31. As a method for forming the pointed object 33, a method of forming the pointed object 33 by pressurizing the anti-slip plate 31 or a method of forming the pointed object 33 and the anti-slip plate 31 as a whole can be used.
[0055] The anti-sway component 30 is described by taking the case where the thickness of the leather or fiber fabric is less than the length of the insertion part 10b-2 as an example, but is not limited to this. When the thickness of the leather or fiber fabric is greater than the length of the insertion part 10b-2, that is, the thickness is thicker, the anti-sway component 30 can be installed on one side or both sides of the leather or fiber fabric when the first combining component 10a and the second combining component 10b are combined, thereby preventing the leather or fiber fabric from being damaged by the first combining component 10a and the second combining component 10b that are combined under pressure.
[0056] Regarding the structure of the male button component 20, when the coupling portion 10a-2 is embedded and coupled to the insertion portion 10b-2, the coupling protrusion 21 penetrates into the through holes 10a-1, 10b-1, and on the opposite side of the button plate 22 equipped with the snap-fit groove 21-1, at the end of the rod portion 23 that penetrates the leather or fiber surface, there is formed an inner hollow support portion 23-1 that can be cut open with the aid of a punch.
[0057] Regarding the installation of the male buckle component 20,
[0058] As shown in the attached figure Figure 4a As shown, after a small hole of a certain size is punched on the leather or fiber fabric F and the rod 23 is embedded in the small hole, the button plate 22 will be tightly attached to and blocked by the leather or fiber fabric F. At this time, by putting it into a clamp not shown in the figure and pressurizing the rod 23, the internal hollow production part 23-1 can be unfolded and cut like a petal, so that it can be fixed to the leather or fiber fabric F.
[0059] As shown in the attached figure Figure 4b As shown, when the snap-fit protrusion 21 of the installed male snap component 20 is inserted into the through holes 10a-1, 10b-1 of the female snap component 10, the spring component 40 installed in a "C" shape between the insertion portion 10b-2 and the coupling portion 10a-2 will be expanded outward with the help of the snap-fit protrusion 21, and when a part of the snap-fit protrusion 21 is inserted, the spring component 40 will be narrowed with the help of elasticity and return to the original position of the snap-fit groove 21-1, thereby combining the female snap component 10 and the male snap component 20.
[0060] On the contrary, regarding the method of separating the female buckle component 10 and the male buckle component 20 in the engaged state, when the spring component 40 is expanded by applying external force to one side of the female buckle component 10 and the male buckle component 20, it will disengage from the snap-fit groove 21-1, thereby separating the female buckle component 10 and the male buckle component 20.
[0061] The cross section of the spring component 40 is shown in the accompanying drawings. Figure 5a to Figure 5c As shown, you can choose to use one of a circle, a square, and a rectangle.
[0062] In the present invention as described above, since the diameter of the spring component 40 can be changed by means of elastic force, the convenience of using the spring component regardless of the size (diameter) of the snap-fit protrusion formed on the male buckle component can be achieved, and since the thickness of leather and fiber fabrics is relatively thin, after the female buckle component and the male buckle component are combined, even in the case of thin thickness of leather and fiber fabrics, the female buckle component can be prevented from sliding or shaking, thereby preventing the female buckle component from being separated from leather and fiber fabrics, and further, since the diameter of the spring component can be deformed, the spring can be prevented from being deformed and thereby ensured to be used for a long time, and the leather or fiber fabric can be prevented from being damaged by the first combining component and the second combining component.
