Device for seamless attachment of buttons for use on buttons provided with conventional holes, comprising a base element to be placed under the button between the button itself and cloth, wherein such a base element comprises through holes intended to at least partially coincide with the button holes, and wherein said through holes are internally provided with retaining means, preferably in the form of annular flats or projecting ridges, as well as fastening means, preferably in the form of rivet-like elements to be inserted on one side in the button holes to downwardly project into said base element, and on the other side to be inserted in the cloth for similarly engaging said base element, the engagement from one to the other side being carried out by means of the projections provided on the shank of said rivet-like elements hooking on said annular flats or projecting ridges provided internally of the base element holes.
A device for seamless attachment of buttons intended to be used on buttons having conventional holes, the device comprising a base element to be placed under the button, said base element including through holes designed to coincide with the button holes, and wherein retaining means are provided within said through holes for a fastening counter-element of the button, fastening means to be inserted in the button holes and designed for engagement with flats or projecting ridges thereof in said retaining means provided in said through holes, and at least one fastening head for insertion through the fabric or cloth material, intended to pass through retaining means provided in a through hole of said base element.
A device as set forth in any of the preceding claims, wherein where four-hole buttons are concerned, the upper rivet-like elements and the lower base element are so arranged that fastening occurs on two holes of the button located at the two ends of a diagonal in a square, at the vertices of which the four holes of the button are arranged.
