Abstract

A face shield comprising a frame (1), a glass (2) attached to the frame, a padding (3) between the frame and the face and an attaching portion, for example, a ribbon (4) encircling the head, and to which face shield air is led. The frame is hollow so that the air led into the face shield is directed into the hollow frame and the frame comprises openings through which the air is discharged inside the face shield. <IMAGE>

Description

15 20 25 30 40 ï ;f .I Hífl' 505 34? 2 digt med den. Det finns även utrymme för glasögon inuti an- siktsmasken. 15 20 25 30 40 ï; f .I Hí fl '505 34? 2 poems with it. There is also space for glasses inside the face mask.

En utföringsform av uppfinningen kännetecknas av att öppningarna är långsträckta slitsar placerade vid ramens sidor och riktade mot glaset, så att luften utströmmas för att andas framför ansiktet och för att samtidigt bortblåsa eventuell imma från glasets insida. Följaktligen erhålls tillräckligt med luft för såväl andning som avlägsnande av imma t.o.m. när bäraren av masken andas kraftigt eller talar. .An embodiment of the invention is characterized in that the openings are elongate slots located at the sides of the frame and directed towards the glass, so that the air is expelled to breathe in front of the face and to simultaneously blow away any mist from the inside of the glass. Consequently, sufficient air is obtained for both breathing and removal of mist up to and including when the wearer of the mask breathes heavily or speaks. .

En annan utföringsform av uppfinningen kännetecknas av att stoppningen mellan ramen och ansiktet består av skumplast med öppna celler, så att den luft som har införts för andning kan tillsammans med utandningsluften utträda genom stoppningen från ansiktsmaskens insida. övertryck upprätthålles konstant i ansiktsmasken, så att det finns ett kontinuerligt luftflöde genom stoppningen. Stoppningspartiet kan framställas på sådant sätt, att det enkelt kan ändras för att upprätthålla hygien- krav. Det kan exempelvis innehålla ett tejpfäste. De utbytbara stoppningarna kan vara av olika storlek och tjocklek, varigenom bästa passform uppnås för ansikten av olika storlek.Another embodiment of the invention is characterized in that the padding between the frame and the face consists of foam cells with open cells, so that the air which has been introduced for breathing can, together with the exhaled air, exit through the padding from the inside of the face mask. overpressure is constantly maintained in the face mask, so that there is a continuous flow of air through the padding. The padding portion can be made in such a way that it can be easily changed to maintain hygiene requirements. It may, for example, contain a tape bracket. The replaceable pads can be of different sizes and thicknesses, whereby the best fit is achieved for faces of different sizes.

Uppfinningen beskrivs närmare i det följande med hän- visning till bifogade ritningar, på vilka fig. 1 är en diago- nalfrontvy av ansiktsmasken, fig. 2 är en sidovy av ansiktsmas- ken och fig. 3 är en snittvy av ansiktsmasken.The invention is described in more detail below with reference to the accompanying drawings, in which Fig. 1 is a diagonal front view of the face mask, Fig. 2 is a side view of the face mask and Fig. 3 is a sectional view of the face mask.

Ansiktsmasken innefattar en ram 1, ett glas 2 fastsatt vid ramen, en stoppning 3 placerad mellan ramen och ansiktet och ett band 4, vilket åtdrages runt huvudet. Luft inleds i ansiktsmasken genom en slang 5. Ramen 1 är ihålig, så att den in i ansiktsmasken förda luften riktas in i den ihåliga ramen 1, vilken innefattar öppningar 6, genom vilken luft utströmmas in i ansiktsmasken. Öppningarna 6 är långsträckta slitsar placerade vid ramens 1 sidor och riktade mot glaset, så att luften utströmmas framför ansiktet för andning och samtidigt för bortblåsníng av eventuell imma från glasets inneryta.The face mask comprises a frame 1, a glass 2 attached to the frame, a padding 3 placed between the frame and the face and a band 4, which is tightened around the head. Air is introduced into the face mask through a hose 5. The frame 1 is hollow, so that the air introduced into the face mask is directed into the hollow frame 1, which comprises openings 6, through which air flows out into the face mask. The openings 6 are elongate slits placed at the sides of the frame 1 and directed towards the glass, so that the air flows out in front of the face for breathing and at the same time for blowing away any mist from the inner surface of the glass.

Stoppningen 3 mellan ramen 1 och ansiktet består av en skum- plast med öppna celler, så att luften som införts för andning tillsammans med utandningsluften kan utträda genom stoppningen från ansiktsmaskens insida.The padding 3 between the frame 1 and the face consists of an open-cell foam plastic, so that the air introduced for breathing together with the exhaled air can exit through the padding from the inside of the face mask.

Särskilt i förening med en fläktanordníng och även till- sammans med komprimerad luft finns behov för en ansiktsmask av ._.Especially in connection with a fan device and also together with compressed air, there is a need for a face mask of ._.

QfHIIc 3 505 347 denna typ, vilken är enkel att använda, är lätt och ej dyrbar.QfHIIc 3 505 347 this type, which is easy to use, is light and not expensive.

Stoppningen behöver nödvändigtvis ej vara utförd enligt exemp- let. Den kan även ha slutna celler eller på något annat sätt vara luftgenomsläpplig, varvid den extra luften avlägsnas genom en separat utträdesöppning. I detta fall avses med glas ej vanligt glasmaterial, utan en transparent skärmplatta, vilken i realiteten består av transparent plast eller PLEXIGLAS eller motsvarande. ur'The padding does not necessarily have to be made according to the example. It can also have closed cells or in some other way be air-permeable, the extra air being removed through a separate outlet opening. In this case, glass does not mean ordinary glass material, but a transparent screen plate, which in reality consists of transparent plastic or PLEXIGLAS or the like. from'
