Abstract

Half masks are used in escape filter equipment. In emergencies even untrained individuals must be capable of putting them on properly, the breathing filters must be used to a maximum and the dead space for the breathing air moved in to and fro respiration must be minimal. In the half mask according to the invention the sealing lips of the mask body which form a breathing air channel on the face of the mask wearer are extended to reach up to the breathing air inlet opening and are tightly connected to this opening. The breathing air channel rests tightly against the face so as to form the minimal dead space for the air breathed to and fro. The void space which forms between the envelope surface of the half mask and the breathing air channel is connected with the environment via one or more pore-like openings for the purpose of pressure equalization. However, these prevent the breathing air channel and hence the dead space from participating in the respiration during the individual inspirations.

Description

Das Fluchtfiltergerät 1 besteht aus der Halbmaske 2, in der das Atemfilter 3 dicht in die Atemlufteintrittsöffnung 4 eingesetzt ist. Die umlaufende Dichtlippe 5 am Halbmaskenkörper 6 verlängert sich, damit ein Atemluftkanal 7 bildend, bis zur Atemlufteintrittsöffnung 4 und ist dort dicht mit dieser verbunden. Die Wandstärke des Atemluftkanals 7 ist derart, daß sie sich, damit eine Gesichtsauflagefläche bildend, dem hineintauchenden Gesicht anschmiegt. Der zum Anpassen notwendige Luftausgleich aus dem Leerraum 8, der sich zwischen dem Halbmaskenkörper 6 und dem Atemluftkanal 7 bil- det, erfolgt über eine oder mehrere porenartige Öffnungen 9. Diese sind so klein, daß es wohl nach aufgesetzter Halbmaske 2 verzögert zu einem Anpassen des Atemluftkanals 7 kommt, ein Mitatmen bei den einzelnen Atemzügen jedoch nicht erfolgt. Der minimale Totraum für die Pendelatemluftmenge bestimmt sich aus dem Volumen des an die Gesichtsform angeschmiegten Atemluftkanals 7. The escape filter device 1 consists of the half mask 2, in which the breathing filter 3 is inserted tightly into the breathing air inlet opening 4. The circumferential sealing lip 5 on the half-mask body 6 is extended to form a breathing air channel 7 to to the breathing air inlet opening 4 and is tightly connected to it there. The wall thickness of the breathing air channel 7 is such that it is so that a face support surface forming, hugs the plunging face. The air balance necessary for adjustment from the empty space 8, which is between the half-mask body 6 and the breathing air duct 7 picture det, takes place via one or more pore-like openings 9. These are like this small that there is probably a delay in adjusting the Breathing air channel 7 comes, but breathing with the individual breaths does not take place. The minimum dead space for the amount of pendulum breathing air is determined from the volume of the Breathing air duct 7 nestled against the shape of the face.

Claims (1)

Patentanspruch: Halbmaske in Pendelatmung zur Verwendung mit einem Atemfilter als Fluchtfiltergerät mit umlaufender Dichtlippe, dadurch gekennzeichnet, daß die umlaufende Dichtlippe (5) als Gesichtsauflagefläche bis zur Atemlufteintrittsöffnung (4) verlängert und dort mit dieser dicht verbunden einen Atemluftkanal (7) darstellend mit dem Halbmaskenkörper (6) einen Leerraum (8) bildet, der über eine oder mehrere porenartige Offnungen (9) im Halbmaskenkörper (6) mit der Umgebung verbunden ist.Claim: Half mask in pendulum breathing for use with a Breathing filter as an escape filter device with a circumferential sealing lip, characterized in that the circumferential sealing lip (5) acts as a face support surface up to the breathing air inlet opening (4) extended and there, tightly connected to this, representing a breathing air channel (7) with the half-mask body (6) forms an empty space (8) which over one or more pore-like openings (9) in the half-mask body (6) is connected to the environment. Die Erfindung betrifft eine Halbmaske in Pendelatmung nach dem Oberbegriff des Patentanspruches. The invention relates to a half-mask in pendulum breathing according to the preamble of the claim. Fluchtfiltergeräte müssen in Notfällen, z. B. bei Bränden in Hotels, auch von Ungeübten sicher aufsetzbar sein und dann ihre Schutzaufgaben erfüllen. Sie werden in Pendelatmung mit Filtern benutzt. Dazu ist es zur maximalen Filterausnutzung notwendig, daß der Totraum, der sich im Atemluftraum bildet, möglichst klein ist. Escape filter devices must be used in emergencies, e.g. B. in case of fire in hotels, can be safely put on even by inexperienced users and then fulfill their protective tasks. They are used in pendulum breathing with filters. In addition it is for maximum filter utilization It is necessary that the dead space that forms in the breathing air space is as small as possible. In der DE-PS 29 48 423 ist ein Fluchtfiltergerät mit einer Schutzhaube und einer inneren Halbmaske bekanntgeworden, das die verschiedenen Gesichtsformen durch eine nach innen gezogene breitere Dichtlippe als Gesichtsauflagefläche ausgleicht. Sie überbrückt damit die verschiedenen Kopfgrößen und Gesichtsformen. In DE-PS 29 48 423 an escape filter device with a protective hood and an inner half mask that shows the different face shapes compensated for by an inwardly drawn, wider sealing lip as a face support surface. It bridges the different head sizes and face shapes. Der sich dabei zwischen der Gesichtsauflagefläche und der Mantelfläche der Halbmaske bildende Hohlraum ist gegenüber der Atmungsluft nicht abgeschlossen, sein Volumen wird bei den Atemzügen jeweils ausgespült und verringert damit quasi die aktive Atemluftmenge für den Maskenträger.The one between the face support surface and the lateral surface the cavity forming the half mask is not closed off from the breathing air, its volume is flushed out with each breath and thus virtually reduced the active air volume for the mask wearer. Aufgabe der Erfindung ist es, eine Halbmaske in Pendelatmung der eingangs genannten Art so zu verbessern, daß der Totraum minimiert wird. The object of the invention is to provide a half mask in pendulum breathing To improve the aforementioned type so that the dead space is minimized. Diese Aufgabe wird erfindungsgemäß bei einer Halbmaske in Pendelatmung der eingangs genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs gelöst. According to the invention, this object is achieved with a half mask in pendulum breathing of the type mentioned by the characterizing features of the claim solved. Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß der sich unter Anpassung an die jeweilige Gesichtsform bildende Leerraum, der von der Atmungsluft völlig abgeschlossen ist, wirklich die kleinste Pendelatemluftmenge und damit den kleinsten Totraum ermöglicht. Das Atemfilter kann damit maximal ausgenutzt werden. Dieses ist gerade für Fluchtfiltergeräte, die besonders klein und leicht sein müssen, ein sehr großer Vorteil. The advantages achieved with the invention are in particular: that the empty space that is formed while adapting to the respective face shape, the is completely cut off from the breathing air, really the smallest amount of pendulum breathing air and thus enables the smallest dead space. The respiratory filter can thus be used to the maximum will. This is especially for escape filter devices that are particularly small and light must be a very big advantage. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher beschrieben. An embodiment of the invention is shown in the drawing and described in more detail below.
