Definitions

  • the present invention relates to a button stopper, and more particularly to a button stopper such as a rivet used for attaching a button such as a bar to a cloth.
  • FIG. 30 shows a bar (button) 30 and a conventional rivet (button stopper) 130.
  • 31 and 32 are sectional views taken along lines LL and MM in FIG.

  • the length in the axial direction of the tip portion 142 is shorter than the length in the axial direction of the body portion 141, and is about 1: 3 in the illustrated example.
  • the bar 30 has an annular plate-shaped flange 31 and a convex portion 32 that swells upward in a substantially dome shape on the radially inner side of the flange 31.
  • the convex portion 32 receives the post 140 of the rivet 130 and defines a space in which it is deformed and locked.

  • the behavior in which the post 140 of the rivet 130 is crimped in the internal space of the convex portion 32 of the bar 30 is as follows. First, the post 140 that has penetrated the fabric upward enters the internal space of the convex portion 32, and the tip 143 of the post 140 strikes the upper end of the convex portion 32. This upper end is supported by an upper die (not shown). After the front end 143 of the post 140 abuts the upper end of the internal space of the convex portion 32, the bar 30 is further lowered, so that the post 140 is crushed in the axial direction in the internal space of the convex portion 32 in the radial direction. Deforms to swell.

  • the horizontal surface of the inner surface of the convex portion 32 of the bar 30 on the side that receives the post 140 extending in the radial direction with the cloth interposed therebetween is also a perfect circle. Therefore, the post 140 that expands in the radial direction presses the fabric against the inner surface of the convex portion 32 with an almost equal force of 360 degrees.

In this case, for example, if washing is repeated, the bar 30 may come off the fabric.
  • the proximal end portion 141 starts to deform first when the rivet 130 is caulked, and the proximal end portion 141 sometimes deformed excessively.
  • the deformed base end portion 141 lifts the dough, whereby the dough is separated from the upper surface of the base 131 of the rivet 130, and a gap is generated between the base 131 and the flange 31 of the bar 30. If the user's finger enters the gap, the user may be injured.

  • the horizontal cross section (cross section perpendicular to the post axis) of the tip of the post is non-circular. Therefore, when the post is caulked, when the tip end of the post expands radially outward in the internal space of the convex part of the bar, the contour of the non-circular shape is compared with the inner side surface of the circular part in the horizontal section of the convex part.

Abstract

L'invention concerne un élément de fixation de bouton (10) pourvu d'une base (11) et d'un montant (20) faisant saillie de la base (11). Le montant (20) comprend une partie d'extrémité de base (21) sur le côté de la base, et une partie d'extrémité avant (22) s'étendant d'une extrémité côté partie saillante de la partie d'extrémité de base (21) à une extrémité en saillie (23) du montant (20). La section transversale perpendiculaire à l'axe du montant (20) de la partie d'extrémité de base (21) est un cercle parfait, et la section transversale perpendiculaire à l'axe du montant (20) de la partie d'extrémité avant (22) est un ovale, et diminue progressivement ou par étapes en direction de l'extrémité en saillie (23). La section transversale de la partie d'extrémité avant (22) du montant (20) peut être un ovale. Dans le montant (20), la longueur dans la direction axiale de la partie d'extrémité avant (22) est supérieure à la longueur dans la direction axiale de la partie d'extrémité de base (21).
