A button wherein the deformable shank of a rivet (which carries the enlarged portion that is to pass through a buttonhole) must be caused to penetrate through a layer of textile or other carrier material and to thereupon enter a retaining device having a portion which deforms the free end portion of the rivet. The rivet is part of the male component of a universal joint which further comprises a socket secured to the rear surface of the enlarged portion. The retaining device has a shallow metallic cup- or pan-shaped enclosure for the rear portion of an elastically deformable insert which is deformed by the shank while the shank penetrates into and is deformed by the enclosure whereby the insert blocks extraction of the deformed shank from the enclosure and sealingly engages the adjacent rear side of the carrier material to prevent the flow of air and/or water through the hole which is formed in the carrier material as a result of penetration of the shank through the carrier material on its way into the retaining device. The insert fills the enclosure and is maintained in stressed condition when the deformation of the shank is completed.
A button for attachment to a penetrable carrier, such as a garment, which has a front side and a rear side, comprising a head having an enlarged portion arranged to pass through a buttonhole and a deformable tubular shank articulately connected with said enlarged portion and arranged to penetrate through the carrier from the front side toward and beyond the rear side of the carrier;
A button for attachment to a penetrable carrier, such as a garment, which has a front side and a rear side, comprising a head having a deformable tubular shank arranged to penetrate through the carrier from the front side toward and beyond the rear side of the carrier;
A button for attachment to a penetrable carrier, such as a garment, which has a front side and a rear side, comprising a head having a deformable tubular shank arranged to penetrate through the carrier from the front side toward and beyond the rear side of the carrier, said head further having an enlarged portion arranged to pass through a buttonhole and having a front surface and a rear surface, and a universal joint connecting said enlarged portion with said shank, said universal joint including an apertured socket at the rear surface of said enlarged portion and a male component including an enlarged section in said socket, said shank being rigid with said enlarged section and being located outside of said socket, said socket having a radially outwardly extending flange at the rear surface of said enlarged portion and means for bonding said flange to said enlarged portion, said bonding means comprising a mass of hardened bonding material and said rear surface being provided with a barrier which is surrounded by said flange and limits the extent of flow of bonding material into said socket prior to hardening of the bonding material;
