Easy fitting can be achieved by providing tapered inclines (6) and rear cut elements on the connector and holders.

Description

Die Erfindung betrifft ein Anschlußteil einer Atemschutzmaske z.B. für Filter, Sprechmembran, Ausatemventil, das direkt in die Sichtscheibe eingesetzt wird und eine leichte Montage und Demontage gewährleistet.The invention relates to a connection part of a respirator e.g. for filters, Speech membrane, exhalation valve that is inserted directly into the viewing window and ensures easy assembly and disassembly.

Der Stand der Technik bietet eine Vielzahl von Lösungen bei denen das Anschlußteil z.B. für Filter, Sprechmembran usw. im Maskenkörper angeordnet ist. Diese Lösungen haben u.a. den Nachteil, daß die Anordnung des Anschlußstückes zu lasten der Größe der Sichtscheibe geht und damit das Sichtfeld des Maskenträgers eingeschränkt wird.The prior art offers a variety of solutions in which the connector e.g. for filters, speech membrane, etc. is arranged in the mask body. These solutions include the disadvantage that the arrangement of the connector at the expense of the size of the lens and thus the field of vision of the Mask wearer is restricted.

Aus der DE-PS 23 04 866 ist lediglich die Durchführung von Drehachsen für Innenscheibenwischer durch eine in der Sichtscheibe angeordnete Buchse bekannt, die mit der erfindungsgemäßen Lösung nicht vergleichbar ist.From DE-PS 23 04 866 is only the implementation of axes of rotation for Internal windshield wipers known from a socket arranged in the viewing window, which is not comparable to the solution according to the invention.

Eine Lösung zur Anordnung eines Anschlußteiles einer Atemschutzmaske direkt in der Sichtscheibe ist von einer Atemschutzmaske im Markt bekannt. Dabei greift ein Clip zum Halten des Anschlußstückes in Aussparungen im Sichtscheibenrand ein. Nachteilig an dieser Lösung sind höhere Fertigungskosten für die Sichtscheibe, eine kompliziertere Handhabbarkeit und die Sicherung der Halterung des Anschlußteiles in nur zwei Kraftaufnahmepunkten. A solution for the arrangement of a connection part of a respirator directly in the window is known from a respirator in the market. there grips a clip to hold the connector in recesses in the edge of the lens on. The disadvantage of this solution are higher manufacturing costs for the Lens, a more complicated handling and securing the bracket of the connection part in only two force absorption points.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Anschlußteil einer Atemschutzmaske z.B. für Filter, Sprechmembran, Ausatemventil zu schaffen, das direkt in die Sichtscheibe eingesetzt wird und eine sichere Halterung sowie eine leichte Montage und Demontage gewährleistet.The present invention has for its object a connector part Respirator e.g. to create for filters, speech membrane, exhalation valve, which is inserted directly into the lens and a secure bracket as well easy assembly and disassembly guaranteed.

Erfindungsgemäß wurde die Aufgabe dadurch gelöst, daß ein Anschlußteil einer Atemschutzmaske entwickelt wurde, daß direkt in der Sichtscheibe angeordnet ist, wobei ein klammerförmiges Verschlußelement auf dem Scheibenrand der Sichtscheibe einer Atemschutzmaske aufliegend so angeordnet ist, daß die Klemmelemente des Verschlußelementes in die Aufnahmeelemente des Anschlußstückes federnd eingreifen, am Anschlußstück Halteelemente als Gegenhalterung für das Verschlußelement angeordnet sind und ein Befestigungselement auf dem Scheibenrand der Sichtscheibe aufliegend angeordnet ist.
Mit der erfindungsgemäßen Lösung ist eine leichte Montage und Demontage des Anschlußteiles möglich und es wird eine hohe Sicherheit für den Maskenträger im Einsatz gewährleistet, da die Kraftaufnahme für die Anschlußteile, z.B. einem Filteranschluß in mindestens drei Punkten erfolgt.
Das erfindungsgemäße Anschlußteil einer Atemschutzmaske ist durch die Ausführung des Verschlußelementes eine besonders platzsparende Lösung mit leichten, handhabungsfreundlichen, kurzen Montagewegen und direktem, kurzem Kraftfluß.
Kostenaufwendige Durchbrüche in der Sichtscheibe oder im Sichtscheibenrand werden bewußt vermieden.According to the invention the object was achieved in that a connection part of a respirator mask was developed that is arranged directly in the viewing window, with a clamp-shaped closure element lying on the pane edge of the viewing window of a respirator mask so that the clamping elements of the closure element resiliently in the receiving elements of the connector intervene, holding elements are arranged on the connector as a counter-holder for the closure element and a fastening element is arranged lying on the edge of the lens of the lens.
With the solution according to the invention, an easy assembly and disassembly of the connection part is possible and a high level of security is guaranteed for the mask wearer in use, since the force absorption for the connection parts, for example a filter connection, takes place in at least three points.
The connection part of a breathing mask according to the invention is a particularly space-saving solution with light, easy-to-use, short assembly paths and direct, short power flow due to the design of the closure element.
Expensive breakthroughs in the lens or in the lens edge are deliberately avoided.

Figure 2
Viewing window

Bei der Montage des erfindungsgemäßen Anschlußteils wird das Anschlußstück 2 von innen so durch eine Sichtscheibenöffnung gesteckt, daß das Befestigungselement 11 in eine Nut 12 des Scheibenrandes angeordnet wird und die Auflagefläche 15 am Scheibenrand 16 anliegt. Anschließend wird das Verschlußelement 1 von außerhalb der Sichtscheibe so aufgesetzt, daß es den Anschlußzylinder 9 umfaßt und die Freimachungen 7 im Gegenwirken mit den Halteelementen 5 wie eine Führung wirken, bis das Verschlußelement 1 am Scheibenrand 16 anliegt. Die erfindungsgemäße Ausführung des Verschlußelementes 1, der Abstand der Klemmelemente 3 ist kleiner als der Durchmesser des Anschlußzylinders 9, bewirkt, daß bei der Montage ein Vorfixieren erreicht wird, d.h. ein Wegrutschen des Verschlußelementes 1 nicht möglich ist, allenfalls die gewollte Entnahme in entgegengesetzter Richtung des Aufsetzens. Durch einen leichten Druck auf das Verschlußelement 1 in Richtung der Aufnahmeelemente 4 des Anschlußstückes 2 greifen die Klemmelemente 3 des Verschlußelementes 1 in die Aufnahmeelemente 4 des Anschlußstückes 2 ein. Dabei gleitet das Verschlußelement 1 unter die Halteelemente 5 und 8 die als Gegenhaltung wirken. Dieser Prozeß wird durch Anlaufschrägen 6 und 17 am Verschlußelement und durch zusätzliche Anlaufschrägen an den Halteelementen 5 erleichtert.
Zur leichten Demontage des Anschlußteils nach einem Einsatz, z.B. zum Reinigen der Sichtscheibe und des Anschlußteils sind am Verschlußelement 1 die Griffelemente 13 angeordnet. Durch einen leichten Druck auf die Griffelemente nach außen können die Klemmelemente 3 aus den Aufnahmeelementen 4 gelöst und das Verschlußelement 1 entgegen der Eingriffsrichtung verschoben werden bis die Freimachungen 7 und die Halteelemente 5 übereinander angeordnet sind. Die Entnahme ist dann leicht in entgegengesetzter Aufsetzrichtung möglich.When assembling the connecting part according to the invention, the connector 2 is inserted from the inside through a viewing window opening in such a way that the fastening element 11 is arranged in a groove 12 in the edge of the window and the bearing surface 15 rests on the edge 16 of the window. Subsequently, the closure element 1 is placed from the outside of the viewing pane in such a way that it encompasses the connecting cylinder 9 and the clearances 7 act as a guide in counteraction with the holding elements 5 until the closure element 1 lies against the pane edge 16. The inventive design of the closure element 1, the distance between the clamping elements 3 is smaller than the diameter of the connecting cylinder 9, has the effect that pre-fixing is achieved during assembly, ie slipping of the closure element 1 is not possible, at most the desired removal in the opposite direction Putting on. By a slight pressure on the closure element 1 in the direction of the receiving elements 4 of the connecting piece 2, the clamping elements 3 of the closing element 1 engage in the receiving elements 4 of the connecting piece 2. The closure element 1 slides under the holding elements 5 and 8 which act as a counterhold. This process is facilitated by bevels 6 and 17 on the closure element and by additional bevels on the holding elements 5.
For easy disassembly of the connection part after use, for example for cleaning the lens and the connection part, the grip elements 13 are arranged on the closure element 1. With a slight pressure on the handle elements to the outside, the clamping elements 3 can be released from the receiving elements 4 and the closure element 1 can be moved against the direction of engagement until the clearances 7 and the holding elements 5 are arranged one above the other. The removal is then easily possible in the opposite direction of placement.

Zur Abdichtung des Verschlußteils gegen die Sichtscheibe wird in die Nut 14 des Anschlußstückes 2 vor dem vorher beschriebenen Einsetzen in die Sichtscheibe ein Dichtring eingelegt, der nach der Montage gegen den Scheibenrand wirkt und eine sichere Abdichtung gegenüber der Umgebungsatmosphäre gewährleistet.
Durch die erfindungsgemäße Ausführung von Verschlußelement 1 und Anschlußstück 2 im Zusammenwirken mit der Sichtscheibe wird eine Kraftaufnahme des Anschlußteiles in sechs Punkten erreicht, Halteelemente 5 und 8, Aufnahmeelemente 4 und Befestigungselement 11.
Die Befestigungselemente 10 und 11 dienen darüber hinaus zur Halterung einer Schutzkappe.To seal the closure part against the lens, a sealing ring is inserted into the groove 14 of the connector 2 before the previously described insertion into the lens, which acts against the edge of the lens after assembly and ensures a secure seal against the ambient atmosphere.
Through the inventive design of the closure element 1 and the connector 2 in cooperation with the lens, a force absorption of the connection part is achieved in six points, holding elements 5 and 8, receiving elements 4 and fastening element 11.
The fastening elements 10 and 11 also serve to hold a protective cap.

In einer weiteren Ausführungsform in der eine Kraftaufnahme in drei Punkten erreicht wird könnten die Halteelement 5, damit auch die Aussparungen 7, sowie das Befestigungselement 11 entfallen. Bei verringerten Herstellkosten steht in diesem Fall ebenfalls eine funktionsfähige Variante zur Verfügung. In a further embodiment in which a force absorption is achieved in three points could the holding element 5, so that the recesses 7, and the fastener 11 is omitted. With reduced manufacturing costs is in In this case, a functional variant is also available.
