Haltevorrichtung für eine Atemschutzmaske zu deren Verbindung mit einem SchutzhelmHolding device for a respirator for connection to a protective helmet
Die Erfindung betrifft eine Haltevorrichtung für eine Atemschutzmaske zu deren Verbindung mit einem Schutzhelm, mit beidseitig an der Atemschutzmaske vorgesehenen Befe tigungshaken, die in an der Außenseite desThe invention relates to a holding device for a respirator for connecting it to a protective helmet, with fastening hooks provided on both sides of the respirator, which hooks into the outside of the
Schutzhelms ausgebildete Hakenaufnähmetaschen einhängbar sind.Protective helmet-trained hook pockets are hooked.
Atemschutzmasken, die nicht unmittelbar am Kopf des Benutzers gehalten sind, sondern mittels einer speziellen Haltevorrichtung an dem Schutzhelm befestigt und am Gesicht des Maskenträgers verspannt werden, sind bekannt. Sie ermöglichen das schnelle Anlegen der Schutzmaske bei aufgesetztem Schutzhelm während eines Einsatzes. Bei einer bekannten Kombination aus Atemschutzmaske und Schutz- heim ist an den gegenüberliegenden Seitenrändern der A- temschutzmaske jeweils eine Haltevorrichtung angebracht, die eine gelenkig an der Atemschutzmaske gehaltene Befestigungsstange mit an deren freiem Ende unter der Wirkung einer Zugfeder teleskopisch fixiertem Befestigungshaken umfasst, während an den seitlich gegenüberliegenden Außenflächen des Schutzhelms jeweils eine Hakenaufnahmetasche ausgebildet ist, in die der jeweilige Befestigungshaken entgegen der Federwirkung eingehängt wird, um die Schutzmaske unter Vorspannung am Gesicht des Maskenträ- gers zu halten.Respirators that are not held directly on the user's head, but are attached to the protective helmet by means of a special holding device and braced on the face of the mask wearer, are known. They enable the protective mask to be put on quickly with the protective helmet on during use. In a known combination of a respirator and protective home, a holding device is attached to the opposite side edges of the respirator, which comprises a fastening rod that is articulated on the respirator with a fastening hook that is telescopically fixed at the free end under the action of a tension spring, while on the a hook-receiving pocket is formed in each of the laterally opposite outer surfaces of the protective helmet, into which the respective fastening hook is hung against the spring action in order to hold the protective mask under tension on the face of the mask wearer.
Das Anlegen der Atemschutzmaske mit dieser verhältnismäßig kompliziert ausgebildeten Haltevorrichtung bereitet insofern Schwierigkeiten, als die unter Federwirkung ste- henden und an einer starren Verlängerungsstange angeordneten Befestigungshaken unter schwierigen Einsatzbedin- gungen nicht einfach zu handhaben sind. In Abhängigkeit von der Kopfgröße des Maskenträgers kann die Atemschutzmaske aufgrund der nicht einstellbaren Federkräfte entweder zu fest oder zu locker am Gesicht anliegen, so dass der Tragekomfort leidet, Dichtheitsprobleme auftreten o- der die Atemschutzmaske leicht verrutschen kann. Eine Einstellung der Federstärke ist zwar indirekt über das Versetzen der Hakenaufnahmetaschen möglich, jedoch sind in diesem Fall die Schutzhelme zwischen den Benutzern mit unterschiedlicher Kopfform nicht mehr austauschbar. Der Erfindung liegt die Aufgabe zugrunde, eine einfach ausgebildete und leicht handhabbare Haltevorrichtung zur Befestigung einer Atemschutzmaske an einem Schutzhelm anzugeben, die einen hohen Trage- und Anlegekomfort und ei- nen sicheren Atemschutz gewährleistet.Putting on the respirator with this relatively complicated holding device presents difficulties insofar as the fastening hooks, which are under spring action and are arranged on a rigid extension rod, under difficult conditions of use. are not easy to use. Depending on the size of the head of the mask wearer, the non-adjustable spring force means that the respiratory mask can either be too tight or too loose on the face so that it is not comfortable to wear, problems with tightness occur or the respirator can slip slightly. Adjusting the spring strength is possible indirectly by moving the hook receiving pockets, but in this case the protective helmets are no longer interchangeable between users with different head shapes. The invention has for its object to provide a simply designed and easy-to-use holding device for attaching a respirator to a safety helmet, which ensures a high wearing and wearing comfort and safe respiratory protection.
Erfindungsgemäß wird die Aufgabe mit einer gemäß den Merkmalen des Patentanspruchs 1 ausgebildeten Haltevorrichtung gelöst. Aus den Unteransprüchen ergeben sich weitere Merkmale und vorteilhafte Weiterbildungen der Erfindung.According to the invention the object is achieved with a holding device designed according to the features of patent claim 1. Further features and advantageous developments of the invention result from the subclaims.
Ein wichtiges Erfindungsmerkmal besteht zunächst darin, dass die Befestigungshaken jeweils an einem flexiblen, längenverstellbaren Spannband angebracht sind und die Befestigungshaken mithin bequem in die Hakenaufnähmetaschen eingeführt werden können. Der sichere Sitz der Maske am Gesicht des Benutzers kann in Abhängigkeit von der Kopfgröße individuell eingestellt werden. In Kombination mit dem biegeschlaffen Spannband sind im Bereich des Befestigungshakens Anschlagelemente vorgesehen, die reib- und formschlüssig am Schutzhelm oder dessen Hakenaufnahmetasche gehalten sind, so das sich die Befestigungshaken selbst bei einer äußeren Krafteinwirkung auf die Atem- schutzmaske nicht aus den Aufnähmetaschen lösen können. Gemäß einem mit den zuvor erwähnten Merkmalen kombinier- ten weiteren wichtigen Erfindungsmerkmal sind den reib- und formschlüssig wirkenden Anschlagelementen zu diesen versetzt angeordnete Gleitelemente zugeordnet, die beim Anziehen der Spannbänder eine selbsttätige Positionierung der Befestigungshaken und eine Ausrichtung der Spannbänder für einen optimalen Sitz der Atemschutzmaske gewährleisten. Unter diesen Voraussetzungen sorgt eine Haltevorrichtung mit Befestigungshaken für einen hohen Anlege- und Tragekomfort sowie einen sicheren Sitz bei einer mit dem Schutzhelm zu verbindenden Atemschutzmaske.An important feature of the invention is first of all that the fastening hooks are each attached to a flexible, length-adjustable tensioning band and that the fastening hooks can therefore be easily inserted into the hook-receiving pockets. The secure fit of the mask on the face of the user can be individually adjusted depending on the size of the head. In combination with the slack tension band, stop elements are provided in the area of the fastening hook, which are held in a frictional and form-fitting manner on the protective helmet or its hook pocket, so that the fastening hooks cannot come loose from the pocket even if the respirator mask is subjected to external force. According to a combination with the aforementioned features Ten further important features of the invention are assigned to the frictional and form-fitting stop elements, offset sliding elements which ensure automatic positioning of the fastening hooks and alignment of the tensioning straps for an optimal fit of the respiratory mask when the tensioning straps are tightened. Under these conditions, a holding device with fastening hooks ensures a high level of comfort and wearing comfort as well as a secure fit with a breathing mask to be connected to the protective helmet.
In weiterer Ausbildung der Erfindung ist der Befestigungshaken als Griffstück mit ergono isch gestalteten Griffelementen ausgebildet, um die Handhabung der Halte- Vorrichtung auch beim Tragen von Handschuhen weiter zu erleichtern.In a further embodiment of the invention, the fastening hook is designed as a handle with ergonomically designed handle elements in order to further facilitate the handling of the holding device even when wearing gloves.
Die Verbindung des Spannbandes mit dem Befestigungshaken erfolgt mit einem an das Spannband angeformten Halte- stück, das in einer in dem Griffstück ausgebildeten Ausnehmung formschlüssig fixiert ist. An die freie Oberfläche des aus gummielastischem Material bestehenden Haltestücks sind die aus dem gleichen Material bestehenden Anschlagelemente angeformt, während die Gleitelemente am Seitenrand der Ausnehmung des aus einem festen Material mit guten Gleiteigenschaften bestehenden Griffstückes ausgebildet sind.The tensioning strap is connected to the fastening hook with a holding piece molded onto the tensioning strap, which is positively fixed in a recess formed in the handle. The stop elements made of the same material are molded onto the free surface of the holding piece made of rubber-elastic material, while the sliding elements are formed on the side edge of the recess of the grip piece made of a solid material with good sliding properties.
Die Haltevorrichtung ist somit auch konstruktiv einfach und kostengünstig ausgeführt.The holding device is thus also structurally simple and inexpensive.
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:

Gemäß der Darstellung in Fig. 1 ist an einem Scheibenrahmen 1 einer Atemschutzmaske 2 seitlich gegenüberliegend jeweils eine Haltevorrichtung 3 mit Hilfe eines Bügels 4 befestigt. Am freien Ende des Bügels 4 ist eine Verriege- lungsvorrichtung für ein Spannband 10, die eine am Umfang profilierte Klemmrolle 5 und eine unter Federwirkung verschwenkbare Klemmtaste 6 umfasst, angeordnet. Außerdem ist am Bügelende ein Haltering 7 zur Befestigung eines Nackenbandes 8 vorgesehen. Mit dem Nackenband 8 kann die Atemschutzmaske 2 bei Nichtbenutzung um den Hals des Maskenträgers gehängt werden und steht somit jederzeit für eine Benutzung zur Verfügung. Die Haltevorrichtung 3 umfasst ferner das in Querrichtung verlaufende, im Abstand angeordnete Raststege 11 aufweisende Spannband 10, das zwischen der Klemmrolle 5 und der Klemmtaste 6 geführt und entsprechend dem Abstand der Raststege 11 arretierbar ist, und zwar in der jeweils gewünschten Position zum dichten Anlegen der Atemschutzmaske an das Gesicht des Maskenträgers . An dem von der Verriegelungsvorrichtung entfernten Ende des Spannbandes 10 ist ein Haltestück 12 einstückig angeformt, auf dessen freier Oberfläche Anschlagelemente 13 ausgebildet sind. Das Spannband 10, das Haltestück 12 und die Anschlagelemente 13 bestehen aus einem gummielastischen Material. In das Spannband 10 ist eine Armierung eingebunden, so dass das Spannband 10 zwar flexibel, aber in Längsrichtung im Wesentlichen nicht dehnbar ist.According to the illustration in FIG. 1, a holding device 3 is attached to a pane frame 1 of a respirator mask 2 laterally opposite by means of a bracket 4. At the free end of the bracket 4 there is a locking device for a tensioning band 10, which comprises a clamping roller 5 profiled on the circumference and a clamping button 6 which can be pivoted under spring action. In addition, a retaining ring 7 is provided on the bracket end for attaching a neck strap 8. The breathing mask 2 can be hung around the neck of the mask wearer when the neck strap 8 is not in use and is therefore available for use at any time. The holding device 3 further comprises the tensioning band 10, which runs in the transverse direction and has a spacing between the locking webs 11, which is guided between the clamping roller 5 and the clamping button 6 and can be locked in accordance with the spacing of the locking webs 11, in the respectively desired position for tightly fitting the Respirator mask on the face of the mask wearer. At the end of the tensioning strap 10 remote from the locking device, a holding piece 12 is integrally formed, on the free surface of which stop elements 13 are formed. The tensioning band 10, the holding piece 12 and the stop elements 13 consist of a rubber-elastic material. Reinforcement is integrated into the tensioning strap 10, so that the tensioning strap 10 is indeed flexible, but essentially not stretchable in the longitudinal direction.
Die Haltevorrichtung umfasst des Weiteren einen mit dem Spannband 10 verbundenen, aus einem biegesteifen Material (Hartkunststoff) bestehenden Befestigungshaken 9, der zur Herstellung der Verbindung zwischen der Atemschutzmaske 2 und einem Schutzhelm (nicht dargestellt) in eine an dessen Außenseiten vorgesehene Hakenaufnahmetasche (nicht dargestellt) eingehängt werden kann. Die Breite der Hakenaufnahmetasche ist größer als die des Befestigungshakens 9, so dass dieser ohne Mühe in die Aufnähmetasehe eingeführt werden kann.The holding device further comprises a fastening hook 9, which is connected to the tensioning band 10 and is made of a rigid material (hard plastic) and which, in order to establish the connection between the respiratory mask 2 and a protective helmet (not shown), is placed in a hook-receiving pocket (not shown) provided on the outer sides thereof. can be hung. The width of the hook receiving pocket is greater than that of the fastening hook 9, so that it can be inserted into the receiving meta without any difficulty.
Die Verbindung zwischen dem Befestigungshaken 9 und dem Spannband 10 erfolgt über ein an den Befestigungshaken 9 anschließendes Griffstück 14, in das eine Ausnehmung 15 eingeformt ist, und das an dem Spannband 10 angeformte Haltestück 12, das in der Ausnehmung 15 formschlüssig gehalten ist, und zwar mit am Anschlussstück 12 angeformten Noppen 21, die in Rastöffnungen 22 in den gegenüberliegenden Seitenrändern 16 des Griffstücks 14 eingreifen, sowie mit einer im hinteren Rand des Griffstücks vorgesehenen Schlitzöffnung 20, durch die das Spannband 10 in- durchgeführt ist. Das formschlüssig in die Ausnehmung 15 eingepasste Haltestück 12 ist so dimensioniert, dass es nicht über die Seitenränder 16 der im Griffstück gebildeten Ausnehmung 15 hinausragt bzw. unterhalb der Oberkante der Ausnehmung endet. Die Anschlagelemente 13 ragen je- doch über die Oberkante der Seitenränder 16 hinaus.The connection between the fastening hook 9 and the tensioning strap 10 takes place via a handle 14 adjoining the fastening hook 9, into which a recess 15 is formed, and the retaining piece 12 formed on the tensioning strap 10, which is held in the recess 15 in a form-fitting manner with knobs 21 integrally formed on the connection piece 12, which engage in latching openings 22 in the opposite side edges 16 of the grip piece 14, and with a slot opening 20 provided in the rear edge of the grip piece, through which the tensioning strap 10 is inserted. The form-fitting holding piece 12 which is fitted into the recess 15 is dimensioned such that it does not protrude beyond the side edges 16 of the recess 15 formed in the handle or ends below the upper edge of the recess. However, the stop elements 13 project beyond the upper edge of the side edges 16.
Am Griffstück 14 sind auf den Seitenrändern 16 der Ausnehmung 15 Gleitschienen 17 ausgebildet, die die Anschlagelemente 13 geringfügig überragen und geringfügig versetzt zu diesen angeordnet sind. Außerdem sind am zum Spannband 10 weisenden Ende des Griffstücks 14 zur Er- leichterung des Abnehmens und Einhängens des Befestigungshakens 9, und zwar auch mit Handschuhen, Griffele- mente 18 sowie im Bereich des Befestigungshaken 9 Griffelemente 19a, 19b, 19c ausgebildet.On the handle 14, 15 slide rails 17 are formed on the side edges 16 of the recess, which project slightly beyond the stop elements 13 and are arranged slightly offset from these. In addition, at the end of the handle 14 facing the tensioning strap 10, easier removal and attachment of the fastening hook 9, specifically also with gloves, grip elements 18 and in the region of the fastening hook 9 grip elements 19a, 19b, 19c.
Beim Anlegen der Atemschutzmaske 2 befinden sich die unteren Enden der Spannbänder 10 im Bereich der Klemmrolle 5 und der Klemmtaste 6, so dass genügend Spielraum zum Einhängen der Befestigungshaken 9 in die Hakenaufnahmeta- sehen am Schutzhelm (nicht dargestellt) besteht. Anschließend werden die Spannbänder 10 zwischen Klemmtaste und Klemmrolle in Abhängigkeit von der Kopfform und Kopfgröße soweit angezogen, dass der Maskenrand ausreichend dicht und komfortabel am Gesicht anliegt. Dabei gleitet der Befestigungshaken 9 auf den Gleitelementen 17 selbsttätig in die vorgegebene Lage in der Hakenaufnahmetasche . Das Spannband 10 ist dabei zwischen Aufnahmetasche und Klemmrolle/Klemmtaste 5, 6 so ausgerichtet, dass die Zugbelastung am oberen Rand des Spannbandes 10 größer als am unteren Rand ist. Diese Position bzw. Belastung desWhen the respirator mask 2 is put on, the lower ends of the tensioning straps 10 are located in the area of the clamping roller 5 and the clamping button 6, so that there is sufficient scope for hanging the fastening hooks 9 into the hook receiving pocket on the protective helmet (not shown). The tensioning straps 10 between the clamping button and the clamping roller are then tightened depending on the shape and size of the head to such an extent that the edge of the mask lies sufficiently close and comfortably against the face. The fastening hook 9 slides automatically on the sliding elements 17 into the predetermined position in the hook receiving pocket. The tensioning strap 10 is aligned between the receiving pocket and the clamping roller / clamping button 5, 6 in such a way that the tensile load on the upper edge of the tensioning strap 10 is greater than on the lower edge. This position or burden of
Spannbandes 10 hat sich als vorteilhaft für einen komfortablen und gasdichten Sitz der Atemschutzmaske erwiesen. Bei einer frontalen Kraftwirkung auf die Atemschutzmaske, zum Beispiel beim Anstoßen an ein Hindernis in engen Räu- men, kann sich der Befestigungshaken 9 aufgrund der Flexibilität des Spannbandes 10 in Verbindung mit den aus dem Haltestück 12 des Spannbandes 10 ragenden gummielastischen Anschlagelementen 13 nicht aus der Hakenaufnähme- tasche am Schutzhelm lösen. Wenn beim Anstoßen an die A- temschutzmaske über das flexible Spannband 10 dennoch eine Kraftwirkung auf den Befestigungshaken 9 ausgeübt wird, wird dessen Bewegung durch die Anschlagelemente 13 verhindert, und zwar formschlüssig an einer Kante der Hakenaufnahmetasche und reibschlüssig aufgrund des gummi- elastischen Materials. Bes gszeichenlisteTension band 10 has proven to be advantageous for a comfortable and gas-tight fit of the breathing mask. With a frontal force effect on the respirator mask, for example when hitting an obstacle in narrow spaces, the fastening hook 9 cannot move out of the way due to the flexibility of the tensioning strap 10 in connection with the rubber-elastic stop elements 13 protruding from the holding piece 12 of the tensioning strap 10 Loosen the hook holder pocket on the protective helmet. If a force is nevertheless exerted on the fastening hook 9 when the respirator mask is pushed against the breathing mask, its movement is prevented by the stop elements 13, namely in a form-fitting manner on an edge of the hook-receiving pocket and in a frictional manner due to the rubber-elastic material.
