Description

Die Erfindung betrifft das Gebiet der Schutzmasken. Sie bezieht sich auf ein Adaptersystem für eine Schutzmaske und auf eine Schutzmaske gemäss dem Oberbegriff der entsprechenden unabhängigen Patentansprüche.The invention relates to the field of protective masks. It relates to an adapter system for a protective mask and to a protective mask according to the preamble of the corresponding independent claims.

STAND DER TECHNIKSTATE OF THE ART

Ein derartiges Adaptersystem ist beispielsweise aus WO 99/26502 A1 bekannt: Eine Schutzmaske ist mittels eines Verstellmechanismus beweglich auf einem Schutzhelm ("Hard hat") befestigt, und kann von einer Position oberhalb des Schutzhelmes in eine Arbeitsposition vor dem Schutzhelm bewegt werden. Der Verstellmechanismus weist einen Verbindungsarm auf, der vom Stirnbereich des Schutzhelmes aus eine Verbindung zur Schutzmaske bildet. Der Mechanismus ist komplex.Such an adapter system is for example off WO 99/26502 A1 A protective mask is movably mounted on a protective helmet ("hard hat") by means of an adjusting mechanism and can be moved from a position above the protective helmet to a working position in front of the protective helmet. The adjusting mechanism has a connecting arm which forms a connection to the protective mask from the front area of the protective helmet. The mechanism is complex.

Auch sind Adapter bekannt, welche auf einem um den Schutzhelm umlaufenden Bügel bestehen, an welchem die Schutzmaske drehbar befestigt ist, wie beispielsweise aus US 7,409,723 .Adapters are also known, which consist of a protective strap surrounding the protective strap on which the protective mask is rotatably mounted, such as, for example US 7,409,723 ,

Bisher bekannte Adaptersysteme weisen keine oder nur eine beschränkte Anpassbarkeit an verschiedene Anwendungssituationen auf.Previously known adapter systems have no or only a limited adaptability to different application situations.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist deshalb Aufgabe der Erfindung, ein Adaptersystem für eine Schutzmaske und eine Schutzmaske der eingangs genannten Art zu schaffen, welche die oben genannten Nachteile behebt und insbesondere eine einfache, Platz sparende Konstruktion aufweisen und gleichwohl vielseitig einsetzbar sind.It is therefore an object of the invention to provide an adapter system for a protective mask and a protective mask of the type mentioned, which overcomes the disadvantages mentioned above and in particular have a simple, space-saving design and are nevertheless versatile.

Diese Aufgabe lösen ein Adaptersystem für eine Schutzmaske und eine Schutzmaske mit den Merkmalen der entsprechenden unabhängigen Patentansprüche.This object is achieved by an adapter system for a protective mask and a protective mask having the features of the corresponding independent patent claims.

Das Adaptersystem für eine Schutzmaske dient also zur bewegbaren Befestigung der Schutzmaske an einem Helm, wobei das Adaptersystem zwei einzelne Adapter aufweist, welche einerseits zum Ankoppeln an eine Anschlussvorrichtung des Helmes mittels einer Helmkupplung und andererseits zur Befestigung an der Schutzmaske mittels einer Maskenkupplung vorgesehen sind, und die Adapter jeweils ein Schwenkgelenk aufweisen, um welches eine am Adapter befestigte Schutzmaske drehbar ist. Dabei weisen die Adapter jeweils einen bezüglich des Schwenkgelenkes drehbaren Schwenkarm auf, wobei der Schwenkarm in seiner Länge verstellbar ist.The adapter system for a protective mask thus serves for the movable attachment of the protective mask to a helmet, wherein the adapter system has two individual adapters, which are provided on the one hand for coupling to a connection device of the helmet by means of a helmet coupling and on the other hand for attachment to the protective mask by means of a mask coupling, and the adapters each have a swivel joint about which a protective mask attached to the adapter is rotatable. In this case, the adapters each have a pivotable with respect to the pivot joint pivot arm, wherein the pivot arm is adjustable in its length.

Dadurch ist also der Abstand zwischen Schwenkgelenk und Schutzmaske verstellbar. Es kann so der Abstand entsprechend dem aktuellen Einsatz der Schutzmaske eingestellt werden. Beispielsweise kann, wenn eine Frischluftzufuhr an der Maske im Stirnbereich angeordnet werden soll, der Abstand vergrössert werden, so dass die Frischluftzufuhr sowohl in der Arbeitsposition der Schutzmaske als auch im hochgeklappten Zustand Platz hat.As a result, so the distance between the swivel joint and protective mask is adjustable. It is thus possible to set the distance according to the current use of the protective mask. For example, if a fresh air supply is to be arranged on the mask in the forehead region, the distance can be increased, so that the fresh air supply has room both in the working position of the protective mask and in the folded-up state.

Vorzugsweise ist der verstellbare Schwenkarm in der kinematischen Kette zwischen Schwenkgelenk und Maskenkupplung angeordnet. In einer anderen Ausführungsform der Erfindung ist der Schwenkarm in der kinematischen Kette zwischen Schwenkgelenk und Helmkupplung angeordnet.Preferably, the adjustable pivot arm is arranged in the kinematic chain between the pivot joint and mask coupling. In another Embodiment of the invention, the pivot arm is arranged in the kinematic chain between the pivot joint and the helmet coupling.

In einer bevorzugten Ausführungsform der Erfindung ist der Schwenkarm von Hand um das Schwenkgelenk drehend in mindestens drei Positionen einrastend verstellbar. Eine erste der Positionen entspricht einer Arbeitsstellung der Schutzmaske vor dem Gesicht des Benutzers. Eine zweite Position entspricht einer vorübergehend hochgeschwenkten Schutzmaske, beispielsweise zum Kontrollieren einer Schweissarbeit. Eine dritte Position des Schwenkarmes entspricht einer Position der Schutzmaske oberhalb des Helmes, wobei vorzugsweise der Schwerpunkt der Schutzmaske in dieser Position zumindest annähernd in einer Mittelebene des Helmes verläuft.In a preferred embodiment of the invention, the swivel arm is manually adjustable to rotate around the swivel joint in at least three positions. A first of the positions corresponds to a working position of the protective mask in front of the user's face. A second position corresponds to a temporarily raised protective mask, for example for checking a welding job. A third position of the swivel arm corresponds to a position of the protective mask above the helmet, wherein preferably the center of gravity of the protective mask in this position extends at least approximately in a median plane of the helmet.

Diese Mittelebene ist eine senkrechte Ebene durch den Helm (wobei der Helm in der Normalposition ist, entsprechend einer aufrechten Kopfposition der Person, welche den Helm trägt), welche einen vorderen Teil des Helmes von einem hinteren Teil trennt. Anders gesagt verläuft die Mittelebene im Wesentlichen durch die beiden Punkte an der breitesten Stelle links und rechts des Helmes sowie durch den höchsten Punkt oder den Punkt oben in der Mitte der Helmschale. Im Bereich der Mittelebene sind bei vielen Helmen links und rechts standardardisierte Anschlussschlitze zum Einstecken von Zusatzgeräten wie Schutzbrillen, Ohrenschützer etc. ausgeformt.This median plane is a vertical plane through the helmet (with the helmet in the normal position, corresponding to an upright head position of the person wearing the helmet) separating a front part of the helmet from a rear part. In other words, the median plane passes essentially through the two points at the widest point to the left and right of the helmet and through the highest point or point in the top center of the helmet shell. In the area of the mid-plane, many helmets on the left and right have standardized connection slots for inserting additional devices such as goggles, earmuffs, etc.

Indem die Schutzmaske in der dritten Position senkrecht oberhalb des Helmes angeordnet ist, ist das Gewicht der Kombination von Schutzmaske und Helm ausgeglichen verteilt. Die Kombination kann also ohne asymmetrische Belastung des Trägers getragen werden, und der Schutz des Trägers durch den Helm bleibt gewahrt.By the protective mask is arranged in the third position vertically above the helmet, the weight of the combination of protective mask and helmet is distributed evenly. Thus, the combination can be worn without asymmetric loading of the wearer and protection of the wearer by the helmet is maintained.

In einer bevorzugten Ausführungsform der Erfindung verläuft, wenn die Adapter an einem Helm angebracht sind, die Drehachse des Schwenkgelenkes hinter einer Mittelebene des Helmes. Bei einem typischen Helm bedeutet dies auch, dass die Drehachse des Schwenkgelenkes hinter den Anschlussvorrichtungen des Helmes, in welche die Adapter angebracht sind, verläuft. Vorzugsweise ist dabei auch der Fall, dass die Drehachse des Schwenkgelenkes unterhalb der Anschlussvorrichtungen verläuft. Eine oder alle dieser Massnahmen führen mit sich, dass der Radius, um welchen die Schutzmaske geschwenkt wird, vergleichsweise gross ist. Dies wiederum ermöglicht es, dass die Schutzmaske ungeachtet der genauen Kontur des Helmes an diesem vorbei drehbar ist. Damit ist eine vielfältige Kombination von Schutzmasken mit Helmen möglich.In a preferred embodiment of the invention, when the adapters are attached to a helmet, the axis of rotation of the pivot joint runs behind a Midplane of the helmet. In a typical helmet, this also means that the axis of rotation of the pivot joint runs behind the connection devices of the helmet, in which the adapters are mounted. Preferably, the case is also that the axis of rotation of the pivot joint extends below the connection devices. One or all of these measures lead to the fact that the radius, by which the protective mask is pivoted, is comparatively large. This, in turn, allows the protective mask to be rotatable past it regardless of the exact contour of the helmet. This makes a diverse combination of protective masks with helmets possible.

Eine Längenverstellung des Schwenkarms gemäß einer bevorzugten Ausführungsform stellt eine weitere Möglichkeit dar, den Schwenkradius in diesem Sinne zu vergrößern.A length adjustment of the pivot arm according to a preferred embodiment is another possibility to increase the pivot radius in this sense.

In einer weiteren bevorzugten Ausführungsform der Erfindung weisen die Adapter jeweils ein Justiergelenk auf, um welches das Schwenkgelenk bezüglich der Helmkupplung drehbar ist. Damit ist es möglich, eine Feineinstellung der Relativposition von Schutzmaske zu Helm vorzunehmen, insbesondere um die Arbeitsstellung entsprechend den Präferenzen des Trägers einzustellen.In a further preferred embodiment of the invention, the adapters each have an adjustment joint about which the pivot joint is rotatable relative to the helmet coupling. This makes it possible to make a fine adjustment of the relative position of protective mask to helmet, in particular to adjust the working position according to the preferences of the wearer.

Das Adaptersystem gemäss der Erfindung kann als separater Satz mit zwei Adaptern realisiert werden, oder es kann eine Schutzmaske mit einem bereits montierten Adaptersystem gemäss der Erfindung hergestellt werden.The adapter system according to the invention can be realized as a separate set with two adapters, or it can be made with a protective mask already mounted adapter system according to the invention.

Weitere bevorzugte Ausführungsformen gehen aus den abhängigen Patentansprüchen hervor.Further preferred embodiments emerge from the dependent claims.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Die Figuren 1 bis 5 zeigen verschiedene Ansichten eines Helmes 1 mit einer Schutzmaske 2, welche mit einem Adaptersystem aus zwei Adaptern 3 miteinander verbunden sind. Der Helm 1 ist typischerweise ein Schutzhelm bekannter Art mit einer Kunststoffschale und einem Tragsystem mit einem um den Kopf des Trägers umlaufenden Band (nicht gezeichnet). Die genaue Helmform ist üblicherweise durch nationale Sicherheitsstandards bestimmt. In der Regel weist ein Helm 1 an beiden Seiten, etwa an der breitesten Stelle, oder in der Mitte zwischen Vorderseite 12 und Hinterseite 13 des Helmes 1, standardisierte Anschlussschlitze 11 zum Einstecken von Zusatzgeräten auf. Diese Mitte des Helms entspricht auch einer Mittelebene 14, welche im wesentlichen durch die Mitte des Helmes respektive des Kopfes der Person, welche den Helm trägt, verläuft. In der Regel liegt auch der höchste Punkt des Helmes oder des Kopfes, mindestens annähernd in der Mittelebene 14.The FIGS. 1 to 5 show various views of a helmet 1 with a protective mask 2, which are connected to an adapter system of two adapters 3 together. The helmet 1 is typically a protective helmet of known type with a plastic shell and a support system with a band circulating around the head of the wearer (not shown). The exact helmet shape is usually determined by national safety standards. In general, a helmet 1 on both sides, approximately at the widest point, or in the middle between the front 12 and rear 13 of the helmet 1, standardized connection slots 11 for insertion from additional devices. This center of the helmet also corresponds to a median plane 14, which runs essentially through the center of the helmet or the head of the person wearing the helmet. As a rule, the highest point of the helmet or of the head lies at least approximately in the midplane 14.

Die Schutzmaske 2, beispielsweise eine Schweisserschutzmaske, weist unter anderem einen Maskenkörper 21 auf, mit einem darin eingelassenen Sichtfenster 22. Das Sichtfenster 22 weist typischerweise ein Schutzglas oder ein sich automatisch verdunkelndes Filter auf.The protective mask 2, for example a welding protection mask, has inter alia a mask body 21 with a viewing window 22 embedded therein. The viewing window 22 typically has a protective glass or an automatically darkening filter.

Ein Adapter 3 bildet eine verstellbare kinematische Kette zwischen Helm 1 und Schutzmaske 2. Am einen Ende dieser Kette ist der Adapter 3 jeweils mit einer Helmkupplung 31 in einen der Anschlussschlitze 11 gesteckt, am anderen Ende ist er mit einer Maskenkupplung 37 fest und in der Regel lösbar mit der Schutzmaske 2 verbunden. Jeweils zwei Adapter 3, die zueinander spiegelsymmetrisch sind und in die Anschlussschlitze 11 links und rechts des Helmes 1 steckbar sind, bilden ein Adaptersystem.An adapter 3 forms an adjustable kinematic chain between helmet 1 and protective mask 2. At one end of this chain, the adapter 3 is inserted in each case with a helmet coupling 31 in one of the connection slots 11, at the other end it is fixed with a mask clutch 37 and usually releasably connected to the protective mask 2. In each case two adapters 3, which are mirror-symmetrical to one another and can be plugged into the connection slots 11 on the left and right of the helmet 1, form an adapter system.

Die Helmkupplung 31 ist entsprechend einer standardisierten Form der Anschlussschlitz 11 ausgestaltet. Damit muss für einen bestimmten Markt nur der Typ von Helmkupplung 31 angepasst werden, und die übrigen Teile des Adapters 3 können unverändert bleiben. Vorzugsweise ist der Adapter 3 von unten her in den Anschlussschlitz 11 steckbar und gesteckt.The helmet coupling 31 is designed according to a standardized form of the connection slot 11. Thus, only the type of helmet coupling 31 must be adapted for a particular market, and the remaining parts of the adapter 3 can remain unchanged. Preferably, the adapter 3 can be plugged and inserted from below into the connection slot 11.

In der kinematischen Kette zwischen Helmkupplung 31 und Maskenkupplung 37 liegen, vorzugsweise in dieser Folge: ein Justierelement 33, ein Schwenkarm 35 und ein Verstellelement 36. Diese sind in der folgenden Weise gegeneinander bewegbar oder verstellbar:In the kinematic chain between helmet coupling 31 and mask coupling 37, preferably in this sequence: an adjusting element 33, a pivoting arm 35 and an adjusting element 36. These are mutually movable or adjustable in the following manner:

Das Justierelement 33 ist um ein Justiergelenk 32 bezüglich der Helmkupplung 31 drehbar verstellbar ( Figur 5 ). Damit ist ein Grundwinkel zwischen Helm 1 und Schutzmaske 2 einstellbar, der sich auf alle Stellungen der Schutzmaske 2 auswirkt. Insbesondere ist damit eine gewünschte Position der Schutzmaske 2 in einer Arbeitsstellung einstellbar. In der gezeigten Ausführungsform der Erfindung geschieht die Einstellung des Justierelementes 33 durch Abschnitte des Justierelementes 33 und der Helmkupplung 31, welche jeweils mit Löchern versehen sind und in verschiedenen Orientierungen mit einer Schraube durch die Löcher fixiert werden können. Diese Verstellung braucht in der Regel ein Werkzeug und wird selten vorgenommen, beispielsweise zur Anpassung des Systems aus Helm 1 und Schutzmaske 2 an einen Benutzer.The adjusting element 33 is rotatably adjustable about an adjusting joint 32 with respect to the helmet coupling 31 ( FIG. 5 ). This is a basic angle between the helmet 1 and 2 protective mask adjustable, which affects all positions of the protective mask 2. In particular, a desired position of the protective mask 2 can thus be adjusted in a working position. In the illustrated embodiment of the invention, the adjustment of the adjusting element 33 is effected by sections of the adjusting element 33 and the helmet coupling 31, which are each provided with holes and can be fixed in different orientations with a screw through the holes. This adjustment usually needs a tool and is rarely done, for example, to adapt the system of helmet 1 and protective mask 2 to a user.

Der Schwenkarm 35 ist um ein Schwenkgelenk 34 bezüglich des Justierelementes 33 drehbar und einrastend verstellbar. Das Einrasten geschieht beispielsweise mittels eines Rastelementes 40, welches federnd am Schwenkarm 35 angeordnet ist, beim Schwenken des Schwenkarmes 35 entlang einer Bahn 38 am Justierelement 33 gleitet und ein Kerben 39 in dieser Bahn 38, entsprechend den Rastpositionen des Adapters 3 respektive der Schutzmaske 2 einrastet. Diese Verstellung geschieht manuell und sehr häufig während der Arbeit mit dem System. Dabei wird die Schutzmaske 2 zwischen einer Arbeitsposition ( Figur 3 ) und einer Mittelstellung ( Figur 2 ) verstellt. Vorzugsweise liegt eine weitere Stellung vor ( Figur 1 ), in welcher die Schutzmaske 2 sich in einer gewichtsmässig ausbalancierten Position über dem Helm 1 befindet, so dass das System aus Helm 1 und Schutzmaske 2 bei längerem Nichtgebrauch der Schutzmaske 2 angenehm zu tragen ist.The pivot arm 35 is rotatable about a pivot joint 34 with respect to the adjusting element 33 and latching adjustable. The latching is done for example by means of a locking element 40 which is resiliently mounted on the pivot arm 35, slides during pivoting of the pivot arm 35 along a path 38 on the adjusting element 33 and a notch 39 in this path 38, corresponding to the detent positions of the adapter 3 and the protective mask 2 engages , This adjustment happens manually and very often while working with the system. In this case, the protective mask 2 between a working position ( FIG. 3 ) and a middle position ( FIG. 2 ) adjusted. Preferably there is another position ( FIG. 1 ), in which the protective mask 2 is located in a weight balanced position over the helmet 1, so that the system of helmet 1 and protective mask 2 is comfortable to wear with prolonged disuse of the protective mask 2.

Das Verstellelement 36 ist entlang des Schwenkarmes 35 verschiebbar ( Figur 4 ). Mit dem Verstellelement 36 fest verbunden, oder einstückig an das Verstellelement 36 angeformt, ist die Maskenkupplung 37 zur Fixierung des Adapters 3 an der Schutzmaske 2. Durch Verschieben des Verstellelementes 36 wird ein Radius der Schwenkbewegung des Schwenkarmes 35 und damit der Schutzmaske 2 eingestellt.The adjusting element 36 is displaceable along the pivot arm 35 ( FIG. 4 ). Fixedly connected to the adjusting element 36, or integrally formed on the adjusting element 36, the mask coupling 37 for fixing the adapter 3 to the protective mask 2. By moving the adjusting element 36, a radius of the pivotal movement of the pivot arm 35 and thus the protective mask 2 is set.

Die Verstellung kann mit einer manuell oder mittels eines Werkzeuges lösbaren Raste oder Fixierung geschehen. Diese Verstellbarkeit erlaubt einen flexibleren Einsatz desselben Adaptertypes mit unterschiedlich grossen Helmen, sowie die Anpassung an unterschiedliche Einsätze eines Helmes 1 mit Schutzmaske 2, beispielsweise in Kombination mit einer Frischluftzufuhr.The adjustment can be done with a manually or by means of a tool releasable detent or fixation. This adjustability allows a more flexible use of the same adapter type with different size helmets, as well as the adaptation to different uses of a helmet 1 with protective mask 2, for example in combination with a fresh air supply.

Der Drehpunkt oder die Drehachse des Schwenkgelenkes 34 befindet sich (bezüglich der Orientierung des Helmes 1 respektive des Kopfes des Helmträgers) hinter und vorzugsweise auch unter der Helmkupplung 31. Damit wird die Länge des Schwenkarmes 35 oder der Radius der Drehbewegung der Schutzmaske 2 grundsätzlich verlängert, und wird eine Positionierung der Schutzmaske 2 in einer ausbalancierten Stellung über dem Helm 1 erleichtert.The pivot point or the axis of rotation of the pivot joint 34 is (with respect to the orientation of the helmet 1 or the head of the helmet wearer) behind and preferably also under the helmet coupling 31. Thus, the length of the pivot arm 35 or the radius of rotation of the protective mask 2 is basically extended, and facilitates positioning of the protective mask 2 in a balanced position over the helmet 1.
