Abstract

The present invention relates to a non-return valve (2, 3, 7) produced in one and the same operation in conjuction with the joint (5) around an air-containing product, such as an air mattress (4), to provide the valve function when the product is inflated.

Description

502 354 2 Figurbeskrivning. 502 354 2 Figure description.

Uppfinningen skall i det efterföljande närmare förklaras med hjälp av utföringsexempel med hänvisning till bifogad ritning i vilken; Fig l visar en backventil i enlighet med uppfin- ningen sedd delvis genomskuren, utförd på en luftmadrass.The invention will be explained in more detail below with the aid of exemplary embodiments with reference to the accompanying drawing, in which; Fig. 1 shows a non-return valve in accordance with the invention, seen partially cut through, made on an air mattress.

Fig 1 visar således backventilelementet 1, som genom sin vinklade utformning 2, tätar och ger backventilsfunk- tion vid övertrycket i den luftfyllda luftbehållande madrassen 4. Backventilen 2, 7 utformas i ett och samma moment vid samman- fogningen 5 av luftmadrassen 4. Materialet i de luftfyllda produkterna skall vara mjuk film 6 av plast eller gummi, som företrädesvis även omfattas av backventilen 2, 7. Vid behov av tömning av luften öppnas backventilen 2, 3, 7. Genom att dra i en flik 8 försvinner vecket 3, som tätat ventilen. I påfyllnads- kanalen 7 kan även en slang 9 fästas in så att fyllning och töm- ning av luft kan ske och manövreras från ett längre avstånd.Fig. 1 thus shows the non-return valve element 1, which due to its angled design 2, seals and provides non-return valve function at the overpressure in the air-filled air-retaining mattress 4. The non-return valve 2, 7 is formed in one and the same moment at the joining 5 of the air mattress 4. the air-filled products should be soft film 6 of plastic or rubber, which is preferably also covered by the non-return valve 2, 7. When the air needs to be emptied, the non-return valve 2, 3, 7 is opened. the valve. In the filling duct 7, a hose 9 can also be fastened so that filling and emptying of air can take place and be operated from a longer distance.

Tömning av luft sker genom att dra i slangen 9.Draining air is done by pulling on the hose 9.
