Abstract

In a respirator mask in which the visor panels can be covered by light-absorbing supplementary panels, first and second snap-in hooks are molded onto opposite sides of the visor panel and a stop is molded onto a corner section to form a guide pocket. The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel, it is first fastened in the guide pocket and on the first snap-in hook. Then the opposite side is locked into the second snap-in hook after flexing the supplementary panel.

Description

Die Erfindung betrifft Atemschutzmasken mit Vorsatzscheiben, die als Lichtfilter vor den im Maskenkörper vorgesehenen Sichtscheiben befestigbar sind.The invention relates to respirators with attachment discs, as a light filter in front of the provided in the mask body Sight glasses are fastened.

In dem aus einem flexiblen Material bestehenden Maskenkörper von Atemschutzmasken sind in Augenhöhe des Benutzers Sichtscheiben eingesetzt. Zum Schutz der Augen vor schädigenden oder das Sehvermögen durch Blendwirkung beeinträchtigenden Lichtstrahlen ist es bekannt, im Bedarfsfall vor den Sichtscheiben aus einem die Lichtstrahlen filternden Material bestehende Vorsatzscheiben anzubringen. Zur Befestigung der Vorsatzscheiben ist am Maskenkörper im Umfangsbereich der Sichtscheiben jeweils ein Halterahmen vorgesehen, während die Vorsatzscheiben am umlaufenden Rand in eine Gummimanschette eingebettet sind. Das Anlegen der Vorsatzscheiben, bei dem die Gummimanschette über den Halterahmen gestülpt wird, ist mühsam und zeitaufwendig und beim Tragen von Schutzhandschuhen mit erheblichen Schwierigkeiten verbunden. In bestimmten Fällen von Lichtstrahlen ist zudem zur Vermeidung von Augenschäden ein umgehender Schutz der Augen erforderlich, der mit den bekannten Vorsatzscheiben-Systemen in der erforderlich kurzen Zeit und ohne fremde Hilfe nicht zu erreichen ist. Abgesehen von der aufgrund des Halterahmens und der Manschette aufwendigen Ausbildung, sind die bisher angewendeten Vorsatzscheiben bzw. deren Befestigungssysteme noch insofern nachteilig, als sie sehr voluminös aufgebaut sind und somit das Ablesen von Instrumenten erheblich erschwert wird. In the mask body consisting of a flexible material Respirators are at eye level of the user Sight glasses used. To protect the eyes damaging or impairing vision due to glare Light rays it is known, if necessary in front of the lenses from one the light rays to attach existing material to the filtering material. To attach the attachment discs is on the mask body in the peripheral region of the lenses each one Holding frame provided while the additional lenses on encircling edge embedded in a rubber cuff are. The attachment of the attachment discs, where the rubber boot slipped over the support frame is cumbersome and time consuming and wearing protective gloves associated with considerable difficulties. In particular Cases of light rays are also to prevent eye damage immediate protection of the eyes is required the required with the known attachment systems in the short time and unassisted is. Apart from the due to the support frame and the cuff elaborate training, are the hitherto applied attachment discs or their attachment systems still disadvantageous in that they are very voluminous and thus the reading of instruments considerably is difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Atemschutzmaske und die an dieser vorübergehend anfügbaren Vorsatzscheiben zur Lichtfilterung so auszubilden, daß im Einsatzfall, das heißt, bei aufgesetzter Maske, unabhängig von fremder Hilfe eine schnelle Befestigung der Vorsatzscheiben möglich ist und darüber hinaus der von den Vorsatzscheiben und dem Befestigungssystem eingenommene, über den Maskenkörper überstehende Raum gering ist.The invention is therefore based on the object, a respirator and the temporarily attachable to this Forming lenses for light filtering in such a way that in Use case, that is, with attached mask, regardless from foreign help a quick attachment of the attachment discs is possible and beyond that of the Attachment discs and the fastening system occupied, over the mask body projecting space is low.

Erfindungsgemäß wird die Aufgabe mit einer gemäß den Merkmalen des Patentanspruches 1 ausgebildeten Atemschutzmaske mit Vorsatzscheiben gelöst.According to the invention, the object with a according to the Features of claim 1 trained respirator solved with attachment discs.

Aus den Unteransprüchen ergeben sich vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungen der Erfindung.From the dependent claims, advantageous developments and expedient embodiments of the invention.

Der Grundgedanke der Erfindung besteht mit anderen Worten darin, daß die biegeelastische und sowohl in den äußeren Konturen als auch in der Wölbung mit der Sichtscheibe identische Vorsatzscheibe unmittelbar auf der Sichtscheibe an in deren gegenüberliegende Seitenränder integrierten Rastmitteln fixiert wird, wobei zur schnellen, lagerichtigen Anordnung der Vorsatzscheibe an die Sichtscheibe ein Führungsmittel angeformt ist. Beim Anbringen der Vorsatzscheibe wird diese zunächst mit Hilfe des Führungsmittels auf der Sichtscheibe ausgerichtet, anschließend in dem ersten Rastmittel gehalten und danach - unter leichtem elastischem Biegen - in dem gegenüberliegenden zweiten Rastmittel endgültig, und zwar dicht auf der Sichtscheibe, fixiert.The basic idea of the invention exists in other words in that the flexurally elastic and both in the outer Contours as well as in the vault with the lens identical Attachment disc directly on the lens integrated into their opposite side edges Locking means is fixed, with the fast, correct position Arrangement of the additional lens to the lens a guide means is formed. When attaching the attachment disc This is done first with the help of the guide aligned on the lens, then held in the first locking means and then - under slight elastic bending - in the opposite second locking means final, and close to the Lens, fixed.

Sowohl die Sichtscheibe als auch die Vorsatzscheibe sind einfach ausgebildet und damit kostengünstig herstellbar. Das Anbringen der Vorsatzscheiben kann bei angelegter Atemschutzmaske ohne Werkzeuge oder fremde Hilfe erfolgen, und zwar in kürzester Zeit. Die Vorsatzscheibe ist sicher fixiert, jedoch bereitet auch deren Entfernen keinerlei Schwierigkeiten. Ein weiterer Vorteil liegt in dem geringen Platzbedarf, da die Bauhöhe nur um die Stärke der Vorsatzscheibe vergrößert wird.Both the lens and the attachment disc are simple and thus inexpensive to produce. The attachment of the attachment discs can with applied respiratory mask done without tools or outside help, in a very short time. The attachment disc is safe fixed, but also prepares their removal no Difficulties. Another advantage is the low Required space, since the height only to the strength of Attachment disc is enlarged.

Das Führungsmittel wird durch einen in einem Eckbereich der Sichtscheibe an deren Rand angeformten Anschlagsteg, der eine Führungstasche definiert, gebildet. Als Rastmittel sind an zwei gegenüberliegenden Rändern der Sichtscheibe Rasthaken angeformt, die jeweils aus einem senkrechten Steg und einem waagerechten Haltesteg bestehen. In dem Bereich, in dem die Vorsatzscheibe in montiertem Zustand unter dem Rasthaken liegt, sind in die Vorsatzscheibe jeweils Vertiefungen so eingeformt, daß die Oberkante der Rasthaken bündig mit der Oberfläche der Vorsatzscheibe abschließt.The guide means will be through one in a corner area the visor integrally formed on the edge stop web, which defines a leadership pocket formed. As locking means are on two opposite edges of the lens Latch hook molded, each consisting of a vertical Bridge and a horizontal jetty exist. In the area where the attachment disc in mounted Condition is below the latching hook, are in the attachment disc each wells formed so that the top edge the catch hook is flush with the surface of the attachment disc concludes.

Nach einem weiteren Merkmal der Erfindung ist die Vorsatzscheibe - zur Sichtscheibe hin gesehen - konkav gewölbt, so daß das zur Montage oder Demontage erforderliche geringfügige elastische Verbiegen der Vorsatzscheibe auf einfache Weise möglich ist. Um für das elastische Verbiegen eine Angriffsfläche zu schaffen, ist im Randbereich der Vorsatzscheibe eine Fingermulde ausgeformt. Dadurch wird die Handhabung der Vorsatzscheibe bei der Montage und Demontage erleichtert.According to a further feature of the invention is the attachment disc - seen towards the lens - concave, so that required for assembly or disassembly slight elastic bending of the attachment disc is possible in a simple way. Um for the elastic Bending to create an attack surface is in the edge area the attachment disc formed a finger recess. Thereby is the handling of the attachment disc during assembly and disassembly easier.

Die Sichtscheibe 1 ist gewölbt ausgebildet und weist eine am Umfang umlaufende Nut 2 auf, über die sie mit dem Maskenkörper einer Atemschutzmaske (nicht dargestellt) verbunden ist.The lens 1 is curved and has a on the circumference circumferential groove 2, via which it with the mask body a respirator (not shown) connected is.

In einem winklig konturierten Randbereich 3 der Sichtscheibe 1 ist eine Führungstasche 4 zum lagerichtigen Anordnen einer Vorsatzscheibe 5 auf der Sichtscheibe 1 ausgebildet. Die Führungstasche 4 wird durch einen von der Sichtscheibenoberfläche senkrecht aufragenden Anschlagsteg 6 gebildet. An den einander gegenüberliegenden Seitenrändern der Sichtscheibe 1 sind erste und zweite Rasthaken 7 und 8 angeformt, die jeweils aus einem senkrecht von der Frontscheibenoberfläche ausgehenden langgestreckten Steg 7a bzw. 8a und einem waagerecht zur Sichtscheibenmitte weisenden Haltesteg 7b bzw. 8b bestehen. Aus Fig. 4 ist erkennbar, daß der Anschlagsteg 6 in den Steg 7a des ersten Rasthaken 7 übergeht.In an angular contoured edge region 3 of the lens 1 is a guide pocket 4 for arranging in the correct position an attachment disc 5 formed on the lens 1. The guide pocket 4 is replaced by one of the Lens surface vertically rising stop ridge 6 formed. At the opposite side edges the lens 1 are first and second locking hooks 7 and 8 formed, each consisting of a vertical extending from the windshield surface elongated Bridge 7a or 8a and a horizontal to the lens center pointing holding web 7b and 8b exist. Out Fig. 4 it can be seen that the stop web 6 in the web 7a of the first latching hook 7 passes.

Die Form der Vorsatzscheibe 4 entspricht hinsichtlich des Kantenverlaufs und der Wölbung der Scheibenfläche im wesentlichen der der Sichtscheibe 1. In dem Randbereich, in dem die Vorsatzscheibe 5 in montiertem Zustand unter dem ersten Rasthaken 7 und dem zweiten Rasthaken 8 liegt, ist in die Vorsatzscheibe 5 eine erste und eine zweite Vertiefung 9, 10 (Materialschwächung) eingeformt, deren Länge und Breite geringfügig größer als die der waagerechten Stege 7b bzw. 8b des betreffenden Rasthakens ist. Auf der Sichtscheibe 1 ist vor der zweiten Vertiefung 10 eine Fingermulde 11 ausgebildet. Die Vorsatzscheibe 5 ist aufgrund der gewölbten Ausbildung in einer Richtung geringfügig, aber dennoch leicht elastisch verformbar.The shape of the attachment disc 4 corresponds in terms of Edge course and the curvature of the disc surface substantially the sight glass 1. In the edge area, in the attachment disc 5 in the assembled state under the first latching hook 7 and the second latching hook 8 is in the attachment disc 5, a first and a second recess 9, 10 (material weakening) molded, whose length and width slightly larger than that of the horizontal Webs 7b and 8b of the respective latching hook is. On the Lens 1 is in front of the second recess 10 a Finger recess 11 is formed. The attachment disc 5 is due the domed formation in one direction slightly, but still slightly elastically deformable.

Das Anbringen der Vorsatzscheibe 5 auf der Sichtscheibe 1 wird folgendermaßen durchgeführt:Attaching the attachment plate 5 on the lens 1 is performed as follows:

Die Vorsatzscheibe 5 wird mit ihrer winkligen (spitzen) Seite in die Führungstasche 4 bis an den Anschlagsteg 6 eingeschoben und nimmt dadurch automatisch ihre lagerichtige Position mit Bezug auf die Sichtscheibe 1 ein. Dabei gleitet die erste Vertiefung 9 in der Vorsatzscheibe 5 unter den ersten Rasthaken 7, so daß die Vorsatzscheibe 5 auf der einen Seite der Sichtscheibe 1 bereits arretiert ist. Durch einen mit dem Finger des Benutzers auf die Fingermulde 11 in Richtung des Pfeils in Fig. 2 ausgeübten Druck wird die Vorsatzscheibe 5 etwas stärker gewölbt, so daß auch die zweite Vertiefung in der Vorsatzscheibe 5 unter den zweiten Rasthaken 8 gelangt, wobei sich die Vorsatzscheibe 5 aufgrund ihrer Eigenelastizität wieder streckt und die zweite Vertiefung 10 unter den zweiten Rasthaken 8 gleitet. Die Vorsatzscheibe 5 ist damit senkrecht zur Sichtscheibenoberfläche sicher arretiert, aber aufgrund des gekrümmten Verlaufs des Haltesteges 8a und des Anschlagstegs 6 und in allen seitlichen waagerechten Richtungen fixiert. Die Vorsatzscheibe 5 kann auf einfache Weise wieder von der Sichtscheibe 1 entfernt werden, indem durch seitlichen Druck auf die Fingermulde 11 die Vorsatzscheibe 5 elastisch stärker gekrümmt wird, so daß sie aus dem zweiten Rasthaken 8 herausgleitet und dann nach oben abgenommen werden kann. The front lens 5 is with its angled (pointed) Side in the guide pocket 4 to the stop bar. 6 pushed in and automatically takes their correct position Position with respect to the lens 1 a. there slides the first recess 9 in the attachment disc. 5 under the first latching hooks 7, so that the attachment disc 5 already locked on one side of the lens 1 is. By one with the finger of the user on the Fingermulde 11 exerted in the direction of the arrow in Fig. 2 Pressure, the lens 5 is slightly more curved, so that the second recess in the attachment disc 5 passes under the second locking hooks 8, wherein the attachment disc 5 due to their inherent elasticity stretches again and the second recess 10 under the second snap hook 8 slides. The attachment disc 5 is so securely locked perpendicular to the lens surface, but due to the curved course of the retaining bar 8a and the stop bar 6 and in all lateral horizontal directions fixed. The attachment disc 5 can easily return to the lens 1 be removed by applying lateral pressure on the Fingermulde 11 the attachment disc 5 more elastic curved is, so that it slides out of the second locking hook 8 and then taken off to the top.

Aufgrund der Ausbildung der Sichtscheibe mit Führungstasche und Anschlagleiste sowie den beiden an den Seitenrändern der Sichtscheibe gegenüberliegend angeordneten Rasthaken ist eine einfache, schnelle und sichere Anbringung der Vorsatzscheiben bei aufgesetzter Atemschutzmaske ohne fremde Hilfe möglich. Die Vorsatzscheibe liegt im wesentlichen auf der Sichtscheibe auf, so daß die Höhe des Aufbaus vor der Sichtscheibe allein durch die Stärke der Vorsatzscheibe bestimmt wird und somit äußerst gering ist. Due to the design of the lens with guide pocket and stop bar and the two at the side edges arranged opposite the lens Latch hook is a simple, fast and secure attachment the attachment discs with attached respiratory mask possible without outside help. The attachment disc is located in essential on the lens, so that the height of the construction in front of the window alone by the strength the attachment disc is determined and thus extremely low is.
