Description

  The present invention relates to an improvement of a fastener structure for fasteners, and more particularly, to an improved structure of a fastener in which a leaf spring is fixed to a cap and a pull tab is easily assembled manually.

  The conventional fastener structure is a connecting structure capable of opening and closing a fastener, and has a convenient operation characteristic, so far, the fastener has been widely applied to bags and clothes. The principle of the fastener is that a fastener tape that can be engaged with each other is opened and closed by reciprocating a fastener. The material of the fastener tape and fastener may be any of metal, nylon, plastic steel, and the like.

  Conventional fastener structures typically include a slide, a hose hitch, a leaf spring, a cap and a pull tab. The hook is extended into the guide groove of the slide by pressing the leaf spring, and one end of the pull tab is positioned below the hose hitch. The cap is secured over the slide so that the hose hitch and leaf spring are positioned within the cap. For example, Patent Document 1 discloses “fastener combination structure (2)”.

  However, in the conventional fastener, the leaf spring is fixed to the slide by a mechanical caulking method. When the leaf spring is fixed to the slide, the hose hitch and the pull tab are also fixed to the slide together, and the pull tab cannot be replaced. However, in actual use, all subcontracting manufacturers have different requirements for pull tabs, and in many cases, different pull tabs are replaced according to their own needs. In particular, some special pull tabs may be assembled only by a mechanical method such as manual because of the small quantity and various changes. In addition, since one type of special pull tab needs to be assembled with a specific machine base, an increase in cost is inevitable.

  Therefore, the present inventor considered that the above-mentioned drawbacks could be improved, and based on the experience accumulated in this area since many years, he conducted intensive observation and research, combined with the operation of academic theory, finally with a rational design and the above-mentioned We proposed the present invention that can effectively improve the defects.

FIG. 4 is a perspective view showing a cap having a fastener structure according to the present invention.

  1 to 4, an improved fastener structure according to the present invention includes a slide 1, a hose hitch 2, a pull tab 3, a leaf spring 4, and a cap 5. A guide groove 11 is formed on the surface and used for blending with a fastener tape (not shown). As shown in FIG. 1, a through hole 12 and a stereotaxic hole 13 are provided at the top of the slide 1. The through hole 12 penetrates to the guide groove 11, and the localization hole 13 is recessed at the top of the slide 1. Further, two stoppers 14 are respectively provided on the both sides of the through hole 12 so as to protrude from the slide 1.

  The hose hitch 2 has a flat base 21, a hook 22, and a fulcrum part 23, and the hook 22 is formed to bend and extend from one end of the base 21 to the lower side of the base 21. The base 21 is shaped so as to refract and extend downward from the base 21.

  The pull tab 3 has a sheet shape, and its outer shape is not limited, and a different pull tab 3 can be selected according to actual requirements. A positioning end 31 is provided at one end of the pull tab 3, and the positioning end 31 is a rod.

  The leaf spring 4 is made of an elastic metal material and formed into a sheet shape, and a fixed end 41 is provided at one end of the leaf spring 4.

  The cap 5 is a lid whose bottom is recessed and has an opening shape, and notches 51 are respectively provided on opposite side surfaces along the longitudinal direction of the cap 5. Two convex portions 52 are provided on the inner wall surface (back surface) of the cap 5, and a limiting surface 521 (as shown in FIG. 4) is provided at the ends of the two convex portions 52. A fixed seat 53 is separately provided on the inner wall surface (back surface) of the cap 5, and the fixed end 41 of the leaf spring 4 is caulked and fixed on the fixed seat 53 of the cap 5.

  In the present invention, at the time of assembly, first, the positioning end 31 of the pull tab 3 is installed above the top of the slide 1 (between the stereotaxic hole 13 and the stopper 14), and then the positioning end 31 of the pull tab 3 is moved. It is located below the center of the hose hitch 2. The hose hitch 2 is provided at the top of the slide 1 so that the hook 22 of the hose hitch 2 extends into the through hole 12 of the slide 1 and the fulcrum 23 extends into the localization hole 13 of the slide 1. The stoppers 14 of the slide 1 were provided on both sides of the hose hitch 2 in order to prevent the hose hitch 2 from causing left and right displacement (in a direction perpendicular to the positioning end 31).

  The both sides of the cap 5 are fixed by being crimped to the slide 1 at a plurality of points, and the slide 1, the hose hitch 2, the pull tab 3, the leaf spring 4 and the cap 5 are joined together to form a fastener structure. Since the leaf spring 4 is fixed in advance to the fixed seat 53 of the cap 5, when the cap 5 is fixedly covered on the top of the slide 1, the hose hitch 2 and the leaf spring 4 are simultaneously accommodated in the cap 5, The limiting surfaces 521 of the two convex portions 52 of the cap 5 are located above the fulcrum portion 23 of the hose hitch 2.
