Benefits of technology

The invention aims to prevent water from passing through a fabric hole that accommodates a snap fastener. This is accomplished through a device that blocked the hole and prevents water from passing through.

Problems solved by technology

One of the problems with mounting snap fasteners on fabric is that water can leak through the hole in the fabric that was cut to allow the snap fastener to be attached.
This can be very problematic, especially when the snap fastener is attached to outdoor clothing, such as rain and snow jackets.

Embodiment Construction

[0017]Referring now in detail to the drawings and, in particular, 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.

[0018]Accordingly, 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...

Abstract

A washer for use in a snap fastener is adapted to be placed over the lower part of a snap fastener component so that the washer rests between the fabric and the lower 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. In its unassembled state, the washer consists of a flat ring surrounding a center protrusion, which is hollow on its inside. To assemble the snap fastener, 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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a washer for a snap fastener. In particular, the invention relates to a washer that prevents water from leaking through clothing on which the snap fastener is mounted.[0003]2. The Prior Art[0004]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.[0005]One of the problems with mounting snap fasteners on fabric is that water can leak through the hole in the fabric that was cut to allow the snap ...
