Abstract

This innovation is a valve which can be applied into already existing or built into new manufactured air- and watertight clothing such as waders and other clothing. The valve enables the person wearing waders to let out accumulated air in the event of submerging. Thus the valve enables the unfortunate person to reach the bottom of the sea, alternatively to swim for his rescue and to undress from the waders. The valve is activated by pulling a string attached to the upper part of the boot-section of the waders - one valve in each leg/boot. When activating the valve a rubber membrane is released and a sufficient amount of air is ventilated very fast.

Description

Air-escape valve for waders and other airtight clothing
POSSIBLE AREAS FOR USE OF THIS NEW INNOVATION:
The innovation consists of a valve for manual operation securing the ventilation of accumulated air from air- and watertight clothing such as waders and other clothing. The valve is designed for building into waders, and is constructed with an inner holding-nut und an outer valve-head separated by a rubber-membrane. Activation is carried out by means of a pull-string-arrangement.
The innovation is expected to be applied for the purpose of reducing the very grave risk of life when using longlegged boots, waders or similar rubber PVC clothing where the hazard is the likelihood of tliis clothing being filled with air, when a person lips over when .standing in the water or if falling into the water.
THE HAZARD OR PROBLEM WHICH THIS INNOVATION SOLVES:
When or if the accident occurs, the waders submerge and the effect of the accumulated air gathered in the waders becomes apparent. Tliis has the consequence that the person's legs and feet .arc lifted to the water-surface. This ag.ain makes it impossible for the person to swim and at worst impossible even to keep the head above the water-surface.
THE NEW TECHNIQUE:
The application of this new innovation entails the possibility to ventilate accumulated air from waders and other similar clothing, thus allowing the person to swim and/or to reach the water-bottom. Or when in deep water to undress from the waders. The valve is activated by pulling the string attached to or built into the upper part of the boot-section of the waders.
HOW THIS TECHNIQUE WORKS:
By activating the pull-string, the rubber-membrane p.art of the valve opens whereby accumulated air is allowed to escape from the clothing. ILLUSTRATIONS:
Photograph no. 1 shows the valve (prototype) applied onto a pair of waders as seen from the outer side.
Photograph no. 2 shows the valve as seen from the inner side.
Photograph no. 3 shows the valve when .activated (open).
Drawings nos. 1, 2, 3 illustrate various parts and components.
A video has been taken showing actual testing of the waders with built-in valves and the valve-function.

Claims

CLAIMS:
A valve with its valve-bearing or valve-housing, a rubber-membrane and a pull-siring activator, all comprising new innovation thereby that :
- The valve .allows accumulated air to escape
- The valve is designed for applications in air- .and watertight materials with thicknesses between 0,01 mm and 200 mm, including materials used for clothing such as waders.
- The valve is activated by manually pulling the spring-pull device. (Illustration 3)
- The valve.-housing is designed with one or more grooves (Ill stration 1), and with one or more air-ventilating holes (Illustration 1), and which guide and hold firm the rubber- membrane, thus securing tight closing of the air-ventilating holes.
- The inner nut (Illustration 2) is designed with a rim and a screw thread or with a spring-log, where the rimpart contains one ore more holes for air-intake or air-escape.
- The membrane (Illustration 3) is designed for a rubber type, characterised thereby that it functions as sealing between the outer and inner parts of this innovation and at the same time serves as sealing of the grooves in the valve-housing.
- The specific part of this rubberlype membrane (illustration 3) serving as the scaling for the valve-housing groove(s) is reinforced at the end-piece to enable a stable fixing of the pull-ring-device.
