Description
Anordning ved gassmaske. Device for gas mask.
Nærværende oppfinnelse gjelder anordning av befestigelse og luftpassasjer i forbindelse med en filterpatron festet til en gassmaske. The present invention relates to the arrangement of attachment and air passages in connection with a filter cartridge attached to a gas mask.
Tidligere har vanligvis filterpatronen vært festet til gassmaskens nedre ansikts-parti ved hjelp av en nippelanordning, hvori inngår ventiler for styring av inn- og utåndingsluften til og fra masken. Nærværende oppfinnelse har til hensikt å tilveiebringe en forenklet innfestings- og ventilanordning for slike gassmasker. Videre har oppfinnelsen til hensikt å tilveiebringe en slik anordning ved gassmasker at filterpatronen raskt og sikkert kan påsettes eller utskiftes samtidig som den foreslåtte holder- og ventilanordning gir en pålitelig funksjonering når masken er i bruk. In the past, the filter cartridge has usually been attached to the lower face of the gas mask by means of a nipple device, which includes valves for controlling the intake and exhalation air to and from the mask. The purpose of the present invention is to provide a simplified attachment and valve device for such gas masks. Furthermore, the invention aims to provide such a device for gas masks that the filter cartridge can be quickly and safely attached or replaced at the same time that the proposed holder and valve device provides reliable functioning when the mask is in use.
Ifølge oppfinnelsen oppnåes ovennevn-te hensikter ved at der til gassmaskens forsider ut for bærerens underansikt er anordnet en holder eller fatning som gri-per om filterpatronen på en slik måte at der mellom patronen og holderen dannes en fri passasje som tjener til utløp for ut-åndingsgassen fra masken, hvorhos der ved holderens indre parti er en ventilanordning som tettende ligger an mot patronens indre ende og tillater at innåndingsluften kun kan passere inn gjennom filterpatronen, mens utåndingsluften passerer ut gjennom den åpning som dannes ved nevnte passasje mellom patron og holder. According to the invention, the above-mentioned purposes are achieved by a holder or socket being arranged on the front sides of the gas mask facing the lower face of the wearer, which grips the filter cartridge in such a way that a free passage is formed between the cartridge and the holder which serves as an outlet for the breathing gas from the mask, where at the inner part of the holder there is a valve device that rests tightly against the inner end of the cartridge and allows the inhaled air to pass through the filter cartridge only, while the exhaled air passes out through the opening formed by said passage between cartridge and holder.
Ifølge en foretrukken utførelsesform er holderen for innfestning av filterpatronen utformet som en hylse med innvendige gripeanordninger for fastholdning av en i denne innført filterpatron, idet hylsens indre tverrsnittareal er større enn filterpatronens ytre tverrsnittsareal. According to a preferred embodiment, the holder for attaching the filter cartridge is designed as a sleeve with internal gripping devices for holding a filter cartridge inserted therein, the inner cross-sectional area of the sleeve being larger than the outer cross-sectional area of the filter cartridge.
Den ventilanordning som fortrinnsvis kommer til anvendelse for innfestningen ifølge oppfinnelsen består av en ringformet klappventil eller membran anordnet rundt en åpning, hvis kanter ligger tettende an mot filterpatronens ende og som tjener som innløpspassasje for innåndingsluften fra patronen til masken. The valve device which is preferably used for the attachment according to the invention consists of an annular flap valve or membrane arranged around an opening, the edges of which rest tightly against the end of the filter cartridge and which serves as an inlet passage for the inhaled air from the cartridge to the mask.
Til bedre forståelse av oppfinnelsen er denne nedenfor beskrevet nærmere i forbindelse med et på vedlagte tegning vist utførelseseksempel. For a better understanding of the invention, it is described below in more detail in connection with an embodiment shown in the attached drawing.
Fig. 1 viser gassmaskens holderanordning sett forfra uten innfestet patron, og Fig. 1 shows the gas mask holder device seen from the front without an attached cartridge, and
fig. 2 viser et snitt gjennom gassmas-kan ifølge oppfinnelsen med filterpatronen på plass. fig. 2 shows a section through the gas mask according to the invention with the filter cartridge in place.
Gassmasken F som kan være av vil-kårlig valgt og forøvrig kjent type er ut for den nedre del av ansiktet utformet med en rundtgående flens som gir permanent innfestning for en holderanordning bestå-ende av en sirkulær hylseformet holder B innvendig forsynt med et antall knaster E. Holderen B og knastene E er slik dimen-sjonert at en filterpatron A av vanlig type kan presses inn i holderen, idet knastene E er forsynt med spor H svarende til filterpatronens endefals. The gas mask F, which can be of an arbitrarily chosen and otherwise known type, is designed for the lower part of the face with a circumferential flange which provides permanent attachment for a holding device consisting of a circular sleeve-shaped holder B internally provided with a number of knobs E The holder B and the lugs E are dimensioned in such a way that a filter cartridge A of the usual type can be pressed into the holder, as the lugs E are provided with grooves H corresponding to the end seam of the filter cartridge.
Holderen B går i den indre ende over i en perforert plate med en sentral åpning K og en kanal av mindre huller G rundt denne. Inne i åpningen K er der festet en elaststisk hylseanordning som med den ytre ende ligger tettende an mot filterpatronen og som ut til sidene går over i en ringformet klappventii eiler membran C ligger over hullene G. The holder B passes at the inner end into a perforated plate with a central opening K and a channel of smaller holes G around this. Inside the opening K, an elastic sleeve device is attached, the outer end of which rests tightly against the filter cartridge and which extends to the sides into an annular flap valve or membrane C lies over the holes G.
Når masken er i bruk vil således under innånding membranen C hindre at ytter-luften kan trekkes inn i masken gjennom hullene G og luftpassasjen I mellom patronen og holderen. Derimot vil åpningen K gi innpassasje for luft suget inn gjennom filtret A. Ved innånding i masken får således kun filteret luft. When the mask is in use, the membrane C will thus prevent outside air from being drawn into the mask through the holes G and the air passage I between the cartridge and the holder during inhalation. In contrast, the opening K will provide passage for air sucked in through the filter A. Thus, when breathing into the mask, only the filter receives air.
Ved utånding vil den ringformede ven-til eller membran C presses ut fra holderplaten og utåndingsluften vil fritt kunne passere ut gjennom hullene G og klaringen I mellom patronen og hylsen. Der en vanlig elastisk klappventii i form av en tynn gummiskive med sentral befestigelse til patronen. When exhaling, the annular valve or membrane C will be pushed out from the holder plate and the exhaled air will be able to pass freely through the holes G and the clearance I between the cartridge and the sleeve. There is an ordinary elastic folding valve in the form of a thin rubber disc with a central attachment to the cartridge.
Det vil umiddelbart sees at fatningen eller holderen ifølge oppfinnelsen gir en usedvanlig enkel og allikevel pålitelig innfestings- og ventilanordning for filterpatronen for en gassmaske. Ventilanordnin-gen er solid og lett tilkommelig når patronen er fjernet slik at den kan ettersees. It will immediately be seen that the socket or holder according to the invention provides an exceptionally simple and yet reliable attachment and valve device for the filter cartridge for a gas mask. The valve device is solid and easily accessible when the cartridge is removed so that it can be inspected.
Gassmaskens fatning behøver nødven-digvis ikke å ha form av en hylse som om-gir den indre ende av patronen, idet fatningen istedenfor kan bestå av hensikts-messige gripeorganer som holder patronen på plass mot en til masken festet under-lagsplate forsynt med nødvendige åpnin-ger eller tilbøyninger for å gi nødvendig utpassasje for utåndingsluften. Likeledes kan ringventilen om ønskes være festet til holderplaten langs den ytre periferi, istedenfor som vist i det beskrevne eksempel, langs den indre. En hensiktsmessig tet-ningskant anordnes da rundt den sentrale åpning K i holderbunnen. The socket of the gas mask does not necessarily have to be in the form of a sleeve that surrounds the inner end of the cartridge, as the socket can instead consist of suitable gripping means that hold the cartridge in place against a base plate attached to the mask, provided with the necessary openings -gives or bends to provide the necessary outlet for the exhaled air. Likewise, if desired, the ring valve can be attached to the holder plate along the outer periphery, instead of, as shown in the described example, along the inner. A suitable sealing edge is then arranged around the central opening K in the base of the holder.
Selv om ovenfor filterpatronen er blitt beskrevet som en bokslignende beholder, fortrinsvis av sylindrisk form forsynt med endefalser, vil det umiddelbart forstås at slike bokslignende filterpatroner også kan være fremstilt uten endefalser, f. eks. av plastmateriale. For fastholdning til gassmaskens fatning vil det da imidlertid være nødvendig å utstyre boksens ender med knaster, spor eller lignende elementer som kan samvirke med tilsvarende elementer på fatningens innside. Although above the filter cartridge has been described as a box-like container, preferably of cylindrical shape provided with end rebates, it will immediately be understood that such box-like filter cartridges can also be produced without end rebates, e.g. of plastic material. For attachment to the gas mask socket, however, it will then be necessary to equip the ends of the box with knobs, grooves or similar elements that can interact with corresponding elements on the inside of the socket.
