  • the present invention relates to a washer for a snap fastener.
  • the invention relates to a washer that prevents water from leaking through clothing on which the snap fastener is mounted.
  • Snap fasteners are comprised of two components that snap into each other to secure two sections of fabric to each other, such as on a coat.
  • the female portion of the snap fastener comprises a lower section with a post that fits through a hole in the fabric, and an upper section that snaps on to the post, over the fabric, so that the fabric is secured between the upper and lower sections.
  • a male portion of the snap fastener is secured to fabric in a similar fashion and then snapped into the female portion to secure two pieces of fabric to each other.
  • a washer adapted to be placed over the lower part of one of the snap fastener components so that the washer rests between the fabric and the bottom part of the snap fastener.
  • the upper part of the snap fastener is placed over the fabric and is pressed into place by a tool press.
  • the washer is made of a resilient material, such as plastic or rubber, which is then squeezed by the tool press to fill in any gaps that would allow water to leak through.
  • the washer In its unassembled state, the washer consists of a flat ring surrounding a center protrusion, which is hollow on its inside.
  • the center protrusion is placed over the central post of the lower part of the snap fastener. The central post with the washer is then inserted through a hole in the fabric to which the snap fastener is to be attached.
  • a tool press is then used to press the upper part down over the central post and into a final position.
  • the washer is compressed and squeezed to fill in any empty space between the bottom part and top part, so that no water can leak through.
  • the tool press also compresses the top of the center post so that it forms a barrier to keep the top part in place.
  • the central protrusion has an outer contour that forms a sidewall, a shoulder section and a closed top.
  • the shoulder section has a diameter that is greater than the diameter of the sidewall and greater than the diameter of the aperture in the upper part.

  • FIG. 1 shows a typical female snap fastener component according to the state of the art.
  • the snap fastener component consists of a lower part 20 having a central post 22 and a surrounding flange 21.
  • a layer of fabric 30 having a hole 31 is placed over central post 21 and an upper part 10 is secured in place over fabric 30, usually with a pressing tool.
  • the disadvantage to this configuration is that water can enter the space between the upper and lower parts, as shown by the arrows, as well as through the central hole in the top part, and can cause the snap fastener to leak. This is a big disadvantage if the snap fastener is being used on outdoor clothing, such as rain or snow jackets.
  • the present invention presents a solution by supplying a washer 40, which is placed between lower part 20 and upper part 10.
  • Washer 40 which is shown in FIGS. 2 and 3, is made of a resilient material, such as rubber or plastic.
  • Washer 40 consists of a central protrusion 42 having a hollow inner cavity 46 and which is surrounded by a flange 41.
  • Protrusion 42 is formed by a sidewall 43, a shoulder section 44 and a closed top 45.
  • Shoulder section 44 has a diameter that is larger than the diameter of sidewall 43.
  • FIGS. 4-7 The assembly of washer 40 onto a snap fastener component is shown in FIGS. 4-7.
  • washer 40 is placed on lower part 20 so that interior cavity 46 covers central post 22 and flange 41 of washer 40 is disposed on top of surrounding flange 21 of lower part 20.
  • central post 22 and protrusion 42 are inserted through a hole 31 in fabric 30.
  • a tool press 15 is placed within sidewall 12 of upper part 10.

  • washer 40 ends up completely surrounding edge 32 of hole 31 of fabric 30, as shown in FIG. 7.
  • flange 41 is pressed down on surrounding flange 21 to create a water-tight seal between upper part 10 and lower part 20.
  • tool press 15 causes top 45 of washer 40 to break, and the top of central post 22 to be deformed and spread out, along the contour of bottom 16 of tool press 15. This spreading of central post 22 creates a cap 25 to prevent upper part 10 from becoming disengaged from lower part 20.
  • Washer 40 also fills in any space between aperture 13 of upper part 10 and central post 22 of lower part 20 to ensure that no water can pass into the interior of the snap fastener.
  • the fully assembled female snap fastener component is shown in FIG. 8, along with a corresponding male snap fastener component.
  • washer 40,400 fills in any gaps between upper part 10,100 fabric 30,300 and lower part 20,200 to seal out any water and prevent leakage through the snap fastener components.
  • the washer according to the present invention is a simple way to prevent water from leaking through the snap fastener to the interior of the garment.

Abstract

La présente invention concerne une rondelle (40) pour utilisation dans un bouton-pression qui est adaptée pour être placée sur la partie inférieure (20) d'un composant de bouton-pression de sorte que la rondelle (40) soit située entre le tissu (30) et la partie inférieure (20) du bouton-pression. La partie supérieure (10) du bouton-pression est placée sur le tissu (30) et est pressée en place par un outil de presse (15). La rondelle (40) est constituée d'un matériau élastique, tel que du plastique du caoutchouc, qui est ensuite pressé par l'outil de presse (15) afin de combler tout espacement qui permettrait une fuite d'eau à travers celui-ci. Dans son état non assemblé, la rondelle (40) est constituée d'un anneau plat entourant une protubérance centrale (42), dont l'intérieur est creux. Afin d'assembler le bouton-pression, la protubérance centrale (42) est placée sur le montant central (22) de la partie inférieure (20) du bouton-pression. Le montant central (22) avec la rondelle (40) est ensuite inséré à travers un trou (31) dans le tissu (30) auquel le bouton-pression doit être fixé.
