This design relates to a button assembly attached to a garment fabric.

Various buttons are known that can be fixed to a fabric without having to sew. The basic form of such buttons consists of a female member, i.e., a button body, and a male member, ie a tack member, the two members being joined together by inserting the male member through the fabric into the female member. The tack bends near the arm when penetrating the fabric. In order to bend the tack well, it has been proposed to use an intermediate member or insert in the arm member, which is arranged to contact the tack so that the tack bends or deforms so that the button assembly is firmly in place in the fabric. To be fixed.

Typical of such inserts known in the art are illustrated in FIGS. 6 and 7 of the accompanying drawings. One is a disc shaped insert (FIG. 6) and the other is a cabin insert (FIG. 7). The two inserts are simply loosely inserted and not fixed in place, causing the inserts to hit an inner wall of the button or linger inside, causing an unpleasant metal sound or sometimes loosening the tack and button body engagement.

In view of the foregoing drawbacks, the object of this invention is to provide an improved button assembly which can be securely held in place in the garment fabric and free of unpleasant metal noise which can be caused by the welding of loosely coupled button members. will be.

According to the present invention, the button assembly consists of a button body, a cap, an insert and a tack, and these members are assembled to be attached to the garment fabric without the aid of sewing. The button body includes a plurality of retainers projecting radially inwards from the hub to securely hold the insert in the hollow barrel hub. The insert is of a helpable structure and includes a central guide protrusion which is installed to deflect the rakes in the opposite direction.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the button assembly 10 according to the present invention includes a button body 11, a cap 12, an insert 13 and a tack 14, and all parts 11-14. ) Is made of metal. The button body 11 has a cabin structure with a hollow cylindrical hub 11a and a horizontal circumferential flange 11b integrated therewith. At the bottom of the hub 11a, a plurality of guide grooves 11c forming a path coinciding with the rakes or toenails of the tack 14, and each guide to accommodate the rakes through the interior of the button body 11 The same number of stepped recesses 11d communicating with the recesses 11c are provided. A plurality of retainers 11e which protrude inwardly from the hub 11a in a similar manner and are one body with a hub are provided for the purpose of the following description. The retainers 11e may take various shapes, such as circular, square or linear, as the case may be, and the number thereof may vary depending on the size of the button and the desired fixing strength.

The insert 13 is of an assisting structure with an annular body 13b that is substantially perpendicular to the assisting head 13a. The assisting head 13a has a recess in the center, and thus has a central circular guide 13c extending inward from the top of the aid for the purpose described below.

The tack 14 usually has a lug base 14a squeezed by a pinch and a plurality of rakes or claws 14b, the rakes 14b of which two are currently shown are the button body 11 and the tack 14. Extend vertically from the base 14a to engage.

The cap 12 is an approximately circular plate 12a having a vertical circumferential flange 12b and a central hole 12c.

To assemble the members of the button assembly 10, the insert 13 is first pressed into the hub 11a of the button body 11. At this time, importantly, the annular body 13b of the insert 13 has an outer diameter slightly larger than the inner diameter of a circle commonly formed by the retainer 11e of the hub 11a, whereby the insert 13 has an annular body 13b. Is elastically deformed at the time of pressure contact with the retainer 11e of the hub 11a shown in FIG. The cap 12 is then placed over the button body 11 and on the button body 11 by folding the vertical circumferential flange 12b over the horizontal flange 11b of the hub 11a as shown in FIG. It is fixed. The tack 14 is engaged with the button body 11 by pushing the rakes 14b into the guide recess 11c and into the stepped recess 11d through the garment fabric F. The rakes 14b penetrate the button material of the recess 11d to abut against the inner wall of the assisting head 13a, wherein the rakes 14b are deflected in opposite directions and do not interfere with each other. Bent along the inner contour of (13); Thus, the circular guide protrusion 13c is provided in the insert 13, which moves the distal ends of the rakes 14b away from each other so that they can bend along the inner wall of the insert 13. Thus, the tack 14 is fully inserted and firmly fixed in place, thereby serving to grip the fabric F on the bottom of the button body 11 as shown in FIG.

3 shows a deformation of the tack 14 where the rakes 14b are not aligned with each other so that their distal ends are separated about the axis of the tack 14. This rake structure allows the rakes to take the proper orientation in opposite directions across the guide projection 13c of the insert 13.

5 shows a deformation of the cap 12 made of a plastic material covered over the entire area of the back side of the button body 11, which is convenient for the button to fit properly against the fabric F or for aesthetic reasons. Are decorated.

However, the insert 13 exhibits an attractive appearance through the hole 12c in the center of the cap 12 shown in FIGS. 1 and 2, and according to this design provides an aid 13. Aesthetic considerations can be excluded.
