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

Beschreibung description
Atemschutzmaske mit VorsatzscheibenRespirator mask with front lenses
Die Erfindung betrifft Atemschutzmasken mit Vorsatzscheiben, die als Lichtfilter vor den im Maskenkörper vorgesehenen Sichtscheiben befestigbar sind.The invention relates to respiratory masks with front lenses that can be attached as light filters in front of the viewing windows provided in the mask body.
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 Be- darfsfall 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. Der Erfindung liegt daher die Aufgabe zugrunde, eine A- temschutzmaske und die an dieser vorübergehend anfügbaren Vorsatzscheiben zur Lichtfilterung so auszubilden, daß im Einsatzfall, das heißt, bei aufgesetzter Maske, unabhän- gig 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.In the mask body made of a flexible material of respiratory masks, viewing windows are inserted at eye level of the user. To protect the eyes from damaging rays of light or impairing vision through glare, it is known to attach front lenses made of a material that filters the rays of light, if necessary, in front of the lenses. A holding frame is provided on the mask body in the circumferential area of the viewing panes to fasten the front screens, while the front screens are embedded in a rubber sleeve on the peripheral edge. The attachment of the front lenses, in which the rubber sleeve is put over the holding frame, is tedious and time-consuming and involves considerable difficulties when wearing protective gloves. In certain cases of light rays, in order to avoid damage to the eyes, immediate protection of the eyes is required, which cannot be achieved with the known lens systems in the required short time and without outside help. Apart from the complex training due to the holding frame and the cuff, the previously used cover plates and their fastening systems are also disadvantageous in that they are very voluminous and therefore make reading instruments much more difficult. The invention is therefore based on the object of designing a respirator mask and the attachment lenses for light filtering which can be temporarily attached to it in such a way that a fast attachment of the attachment lenses and beyond is possible independently of outside help in use, that is to say with a mask attached in addition, the space occupied by the front lenses and the fastening system and protruding beyond the mask body is small.
Erfindungsgemäß wird die Aufgabe mit einer gemäß den Merkmalen des Patentanspruches 1 ausgebildeten Atemschutzmaske mit Vorsatzscheiben gelöst.According to the invention, the object is achieved with a breathing mask with front lenses designed according to the features of claim 1.
Aus den Unteransprüchen ergeben sich vorteilhafte Weiter- bildungen und zweckmäßige Ausgestaltungen der Erfindung.Advantageous further developments and expedient refinements of the invention result from the subclaims.
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 i- dentische 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.In other words, the basic idea of the invention is that the flexible elastic lens, which is identical both in the outer contours and in the curvature with the lens, is fixed directly on the lens to locking means integrated in the opposite side edges thereof, for fast, correct positioning Arrangement of the front lens on the lens, a guide means is molded. When attaching the front lens, it is first aligned on the lens using the guide means, then held in the first locking means and then - with slight elastic bending - finally fixed in the opposite second locking means, tightly on the lens.
Sowohl die Sichtscheibe als auch die Vorsatzscheibe sind einfach ausgebildet und damit kostengünstig herstellbar. Das Anbringen der Vorsatzscheiben kann bei angelegter A- temschutzmaske 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 viewing window and the front lens are simple and therefore inexpensive to manufacture. The attachment of the front lenses can be done without tools or outside help when the respirator mask is on. in no time. The front lens is securely fixed, but removing it is not difficult. Another advantage is the small space requirement, since the overall height is only increased by the thickness of the front lens.
Das Führungsmittel wird durch einen in einem Eckbereich der Sichtscheibe an deren Rand angeformten Anschlagsteg, der eine Führungstasche definiert, gebildet. Als Rastmit- tel 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 Vorsatz- Scheibe jeweils Vertiefungen so eingeformt, daß die Oberkante der Rasthaken bündig mit der Oberfläche der Vorsatzscheibe abschließt.The guide means is formed by a stop web which is formed in a corner region of the viewing window and defines a guide pocket on the edge thereof. As a locking means, locking hooks are formed on two opposite edges of the lens, each consisting of a vertical web and a horizontal holding web. In the area in which the attachment disc lies under the latching hook in the assembled state, depressions are formed in each case in the attachment disk such that the upper edge of the latching hook is flush with the surface of the attachment disk.
Nach einem weiteren Merkmal der Erfindung ist die Vor- satzscheibe - 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 Randbe- reich 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, the front lens - viewed towards the viewing window - is concavely curved, so that the slight elastic bending of the front lens required for assembly or disassembly is possible in a simple manner. In order to create a contact surface for elastic bending, a finger recess is formed in the edge area of the cover plate. This makes handling the front lens easier during assembly and disassembly.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail with reference to the drawing. Show it:

Fig. 4 eine Vorderansicht des Systems nach Fig. 3.4 shows a front view of the system according to FIG. 3.
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) ver- bunden ist.The lens 1 is curved and has a circumferential groove 2, via which it is connected to the mask body of a respirator (not shown).
In einem winklig konturierten Randbereich 3 der Sichtscheibe 1 ist eine Führungstasche 4 zum lagerichtigen Anordnen einer Vorsatzscheibe 5 auf der Sichtscheibe 1 aus- gebildet. 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 angularly contoured edge region 3 of the viewing pane 1, a guide pocket 4 is formed for the correct arrangement of a front pane 5 on the viewing pane 1. The guide pocket 4 is formed by a stop web 6 which rises vertically from the surface of the lens. First and second locking hooks 7 and 8 are formed on the opposite side edges of the lens 1, each of which consists of an elongated web 7a or 8a extending perpendicularly from the windshield surface and a holding bar 7b or 8b pointing horizontally to the lens center. From Fig. 4 it can be seen that the stop web 6 merges into the web 7a of the first locking hook 7.
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 Ver- tiefung 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 front lens 4 corresponds essentially to that of the viewing window 1 in terms of the edge shape and the curvature of the lens surface. In the edge region, in which the front lens 5 lies under the first locking hook 7 and the second locking hook 8 in the assembled state, the front lens 5 a first and a second sales recess 9, 10 (material weakening) molded in, the length and width of which is slightly greater than that of the horizontal webs 7b and 8b of the latching hook in question. A finger recess 11 is formed on the lens 1 in front of the second depression 10. The front lens 5 is slightly deformable in one direction due to the curved design, but is nevertheless slightly elastically deformable.
Das Anbringen der Vorsatzscheibe 5 auf der Sichtscheibe 1 wird folgendermaßen durchgeführt:Attaching the front lens 5 to the lens 1 is carried out 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 lagerich- tige 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 her- ausgleitet und dann nach oben abgenommen werden kann. 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 Anbrin- gung 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. The front lens 5 is inserted with its angled (pointed) side into the guide pocket 4 up to the stop web 6 and thereby automatically assumes its correct position with respect to the lens 1. The first recess 9 slides in the front lens 5 under the first locking hook 7, so that the front lens 5 is already locked on one side of the lens 1. By a pressure exerted by the user's finger on the finger recess 11 in the direction of the arrow in FIG. 2, the front lens 5 is curved somewhat more so that the second recess in the front lens 5 also comes under the second latching hook 8, the front lens being located 5 stretches again due to its inherent elasticity and the second recess 10 slides under the second latching hook 8. The front lens 5 is thus securely locked perpendicular to the surface of the lens, but is fixed in all lateral horizontal directions due to the curved shape of the holding web 8a and the stop web 6. The front lens 5 can easily be removed again from the viewing window 1 by the front lens 5 being elastically curved more strongly by lateral pressure on the finger recess 11, so that it can slide out of the second latching hook 8 and then be removed upwards. Due to the design of the lens with guide pocket and stop bar as well as the two latching hooks located opposite each other on the side edges of the lens, it is possible to attach the lenses easily, quickly and safely with the respirator mask on without outside help. The front lens lies essentially on the viewing window, so that the height of the structure in front of the viewing window is determined solely by the thickness of the front window and is therefore extremely low.
