Definitions

  • This invention relates to a washered rivet for use as a reinforcement to a sewn part of clothing or the like and also to a use of the rivet for clothes.
  • DE-C-836 120 discloses a washer rivet combination to fix a button plate to a garment.
  • the button plate not requiring holding by a die when attached.
  • the washer securing the rivet has a flanged opening with the opening widening as it extends from the main plane of the washer.
  • GB-A-1 479 646 discloses a button with a disc-shaped main portion, a boss and a protruding narrow and point-shaped connection member of plastics material. Extending around the connection member the boss the boss has a raised bevelled profile. The member is intended to be forced through a cloth so that the bevelled edge is brought into contact with one side of the cloth thus keeping the button head (main portion) of the button at a distance from the cloth surface. A round washer having a countersunk central through-hole is then brought into contact with the member so that the member extend through the through-hole.
  • Washered rivets are used in reinforcing the seams, pockets, and other sewn parts of heavy-duty clothes such as jeans and work clothes.
  • the washer 1 is an entirely flat, circular disk with a hole formed in the center.
  • the washer of that shape is combined with a rivet 2 inserted through a cloth, and the end of the rivet shank protruding from the cloth and washer is pressed down by a die 3 to form a second head.
  • the riveting has a shortcoming in that the scrap of the cloth punched by the rivet is left on the headed end 4 of the rivet 2 and affects the head contour unfavorably.
  • the present invention aims at providing a washered rivet which, when set on an article, forms a head sound in shape and appearance with the possibility of separating from the washer being very small.
  • the invention thus provides a washered rivet which is a combination of a washer whose inner peripheral portion around the center hole is depressed downwardly to a truncated conical shape toward the cloth with which the washer comes in contact and a rivet having a flat or more or less rounded shank end.
  • the headless end of the washered rivet of the invention is pressed down to form a second head for fastening purpose, using a die having a cavity larger in diameter than the hole of the washer.
  • a washered rivet 10 embodying the invention comprises a washer 20 whose inner peripheral portion 22 around the center hole is depressed to a truncated conical shape toward a cloth 40 with which it comes into contact and a rivet 30 having a rounded shank end 31.
  • the washer and rivet are combined with the cloth in between and are joined by pressing down the rivet end by means of a die 50 whose cavity 51 has a diameter greater than that of the washer hole.
  • the washer 20 replaces the conventional flat disk, with its inner peripheral portion 22 around the center hole depressed to a truncated conical shape toward the cloth 40 with which it comes into contact.
  • the shank end of the rivet 30, as shown in FIG. 2, may be partly flat as at 31' in lieu of being rounded.
  • the die 50 that closes the rivet 30 of the washered rivet 10 over the washer 20 has a cavity 51 larger in diameter than the hole of the washer 20.
  • the backing base located opposite to the die 50 and below the rivet 30 is not shown.
  • the downward pressing of the shank end 31 or 31' by the die 50 also causes the upper portion of the shank near the shank end 31 or 31' to bulge into a round head 33 larger in diameter than the washer hole, thereby securedly attaching the washer to the cloth as shown in Fig. 5.
  • the shank end of the rivet be sharply pointed.
  • the pointing requires secondary machining.
  • the present invention uses rivets with unpointed shank ends, such as rounded or flat ones in the embodiments described above. Even with an unpointed end, the rivet can be set using a die with a cavity greater in diameter than the washer hole to form a sound head; there occurs no such unwanted deformation that ordinarily results from pressing down with the cloth scrap deposited on the shank end.
  • the combination of rivet and washer of the structure and the method of setting the combination as described above in accordance with the present invention eliminate the undesirable deformation of the shank end or upward sloping of the periphery around the washer hole. Hence the invention precludes any adverse effect on the appearance of the headed end and its periphery or any separation of the rivet and washer from each other.
