79021411-0 2 ningarna i gummit ger i sin Lun störningar i lHLningsytan,vilket yttrar sig som störande veckblidning 3 nämnda yta samt därmed risk för läckage. En annan nackdel är att användaren normalt önskar så litet tryck som möjligt mot näsan, vilket resulterar i att träden höjes felaktigt och tätningen blir otillförlitlig. Enligt föreliggande uppfinning elimineras nackdelarna med trepunkts- fästet på så sätt att det fjädrande elementet kunnat fästas endast i två punkter. Dessutom är fjädringen anpassad så att ingen justering behövs för att ge ett tillräckligt men ändå bekvämt tätningstryck. Uppfinningenskännetecken framgår av följande patentkrav. En utföringsform av uppfinningen åskådliggörs på åtföljande ritning, där figur l visar utförandet i sin helhet och figur 2 gumminabben och hålet i det fjädrande elementet. I figur l syns halvmasken l med två stycken gumminabbar 2. Dessa gumminabbar utföres med rektangulär eller ovalformad tvärsnittsarea passande till motsvarande hål 5 (figur 2) i det fjädrande elementet79021411-0 2 the ings in the rubber give in their Lun disturbances in the hHLning surface, which manifests itself as disturbing creasing 3 mentioned surface and thus risk of leakage. Another disadvantage is that the user normally wants as little pressure as possible against the nose, which results in the trees being raised incorrectly and the seal becoming unreliable. According to the present invention, the disadvantages of the three-point bracket are eliminated in such a way that the resilient element could be fastened in only two points. In addition, the suspension is adapted so that no adjustment is needed to provide a sufficient but still comfortable sealing pressure. Characteristic features of the invention are set forth in the following claims. An embodiment of the invention is illustrated in the accompanying drawing, in which figure 1 shows the embodiment in its entirety and figure 2 the rubber tab and the hole in the resilient element. Figure 1 shows the half mask 1 with two rubber tabs 2. These rubber tabs are made with a rectangular or oval-shaped cross-sectional area fitting to the corresponding hole 5 (Figure 2) in the resilient element. 4. Gumminabbarna 2 har dessutom ett huvud 3 som införes genom nämnda hål 5 samt därmed håller fjäderelementet på plats. Nabbarnas och hålens rektangulära form gör att fjädrande elementet hålls på plats något nedtryckt mot masken över näsan. Längden och tjockleken på skänklarna i fjäderelementet 4 avpassas så att lämplig fjädring samt tryekkraft fås på maskens sidor vid nabbarnas fästpnnkter. Patentkrav l. Ansiktsmask med näsklämma, lämpligen halvmask, k ä n n e t e c k n a d av att masken (l) är försedd med två nabbar (2), lämpligen gumminabbar, vilka fasthåller ett fjädrande element (4), som ger ett tätningstryck på masken vid näsans båda sidor.4. The rubber tabs 2 further have a head 3 which is inserted through said hole 5 and thus holds the spring element in place. The rectangular shape of the hubs and holes means that the resilient element is held in place slightly pressed against the mask over the nose. The length and thickness of the legs in the spring element 4 are adjusted so that suitable suspension and compressive force are obtained on the sides of the mask at the attachment points of the hubs. A face mask with a nose clip, preferably a half mask, characterized in that the mask (1) is provided with two hubs (2), preferably rubber hubs, which hold a resilient element (4), which gives a sealing pressure on the mask at both sides of the nose. . 2.
