Abstract

A strap for respirator masks comprises a head strap piece (1), made from elastically flexible synthetic material, with a strap fixing piece (5) and a head plate (4) with a greater wall thickness than the attached head straps (6). A neck strap, connected to the mask at two fixing points and an extending temple strap, which may be introduced in a detachable and length adjustable manner into fixing clips (7) attached to the head straps (6), are fixed to the strap fixing piece. The head strap piece thus consists of a straight and a curved piece. The crown-shaped embodiment with the elastic temple band is associated with good fitting and wearing properties and low maintenance requirements.

Bänderung für eine Atemschutz-VollmaskeStrap for a full face mask
Die Erfindung betrifft eine Bänderung mit für Atemschutz- Vollmasken, bestehend aus einem Kopfbandteil mit zwei an der Maske an zwei Punkten befestigten Kopfbändern und einem gemeinsamen Bandhalteteil für an zwei weiteren Maskenpunkten längenverstellbar gehaltene Nackenbänder.The invention relates to a harness for full face masks, consisting of a headgear part with two headgear straps attached to the mask at two points and a common strap holding part for neck straps adjustable in length at two further mask points.
Eine derartige Bänderung aus flexiblem, aber in Längsrichtung nicht elastisch dehnbarem Kunststoff- Material mit einer Vierpunkt-Befestigung der Bandenden an der Maske ist beispielsweise aus der JP 2000-102624 bekannt . Diese Bänderung mit nur vier Befestigungspunkten ist auf einfache Weise an der Maske montierbar, so dass auch eine leichte Reinigungsmöglichkeit gegeben ist. Sie ist jedoch insofern nachteilig, als ein fester Sitz der Maske, insbesondere bei mit einer stärkerenSuch a band made of flexible but not elastically stretchable plastic material in the longitudinal direction with a four-point fastening of the band ends on the mask is known for example from JP 2000-102624. This strap with only four attachment points can be easily mounted on the mask, so that it is also easy to clean. However, it is disadvantageous in that a tight fit of the mask, especially in the case of a stronger one
Schweißbildung verbundenen hohen Belastung des Benutzers oder wenn an der Maske aufgrund von an dieser angebrachten Geräten wie Schweißervorsatz und dgl . zusätzliche Kräfte wirken, nicht gewährleistet ist. Zwar wird in der JP 2000-102624 in Verbindung mit einer Fünfoder Sechs-Punkt-Befestigung mit an jedem Bänderende vorgesehenen Einstellelementen auch die Verwendung von integral an die Befestigungsplatte angeformten, d.h. aus dem gleichen Material wie die Befestigungsplatte bestehenden Seitenbändern vorgeschlagen, jedoch ist auch diese hinsichtlich der Bandeinstellung und -befestigung aufwendige Bänderung nicht geeignet, bei Belastung eine sichere Positionierung der Atemschutzmaske am Kopf des Benutzers zu gewährleisten. Die Fünf- oder Sechs-Punkt- Bänderung ist zudem mit einem höheren Montage- undSweating associated with high load on the user or when on the mask due to attached to this equipment such as welding attachment and the like. additional forces act, is not guaranteed. In JP 2000-102624 in connection with a five or six-point fastening with adjusting elements provided at each end of the band, the use of integrally molded onto the fastening plate, i.e. made from the same material as the fastening plate existing side straps, but this strap, which is complex in terms of strap adjustment and attachment, is also not suitable for ensuring that the respirator mask is securely positioned on the user's head when under load. The five or six point harness is also with a higher assembly and
Einstellaufwand verbunden und erschwert die Reinigung der Maske. Ein weiterer Nachteil der aus der JP 2000-102624 bekannten Bänderung ist schließlich darin zu sehen, dass die flexible Bänderung recht labil ist und daher das Anlegen der Maske für ungeübte Personen schwierig und mit erheblichem Zeitaufwand verbunden ist. Der Erfindung liegt daher die Aufgabe zugrunde, eine Bänderung für Atemschutzmasken anzugeben, die einfach zu handhaben und zu warten ist und sowohl bei körperlicher Belastung des Benutzers als auch bei erhöhtem Maskengewicht einen sicheren Sitz der Maske gewährleistet .Adjustment effort connected and difficult to clean the mask. Another disadvantage of the strapping known from JP 2000-102624 is finally to be seen in the fact that the flexible strapping is quite unstable and therefore the mask is difficult for inexperienced persons and is associated with a considerable expenditure of time. The invention is therefore based on the object of specifying a strap for respirator masks which is easy to handle and maintain and which ensures a secure fit of the mask both when the user is under physical strain and when the mask weight is increased.
Erfindungsgemäß wird die Aufgabe mit einer Bänderung mit Vierpunkt-Befestigung gemäß den Merkmalen des Patentanspruches 1 gelöst.According to the invention the object is achieved with a harness with four-point attachment according to the features of claim 1.
Der Grundgedanke der Erfindung besteht mit anderen Worten darin, dass das aus Kunststoff bestehende Kopfbandteil zwischen dem Bandhalteteil und den Kopfbändern eine biegeelastisch steife Kopfplatte aufweist, gegenüber der die Kopf änder deutlich flexibler sind. Dadurch wird ein im Kopfbandbereich gekrümmtes und im Bereich der Kopfplatte gerades, leicht und schnell anlegbares Kopfbandteil gebildet, das in Verbindung mit einem an dem Bandhalteteil und an Haltetaschen der Kopfbänder angebrachten dehnungselastischen Schläfenband etwa eine Hutform mit gekrümmten Kopfbändern und einer geraden Kopfplatte annimmt und daher haubenförmig geöffnet auf den Kopf gesetzt werden kann, ohne dass die Bänderung zuvor geordnet oder ausgerichtet werden muß oder sich verdrehen kann.In other words, the basic idea of the invention is that the plastic headband part between the band holding part and the headbands has a flexurally rigid head plate, against which the head changes are significantly more flexible. This forms a headband part that is curved in the headband area and straight and easy to put on in the area of the headplate, which, in conjunction with an elastic-elastic temple band attached to the band holding part and to holding pockets of the headbands, assumes a hat shape with curved headbands and a straight headplate and is therefore hood-shaped can be opened upside down without the straps having to be arranged or aligned beforehand or twisting.
Das Kopfbandteil besteht aus einem gleitfreudigen Kunststoff und gleitet daher im wesentlichen reibungsfrei über die Kopfhaare. Andererseits wird aber die Maske durch das elastische Schläfenband auch bei hoher Belastung des Benutzers und entsprechender Feuchtigkeitsbildung oder erhöhtem Maskengewicht dennoch sicher und 'abdichtend am Kopf des Benutzers gehalten.The headband part consists of a slippery plastic and therefore slides over the head hair essentially without friction. On the other hand, the mask is nevertheless held securely and 'sealingly on the user's head by the elastic temple band, even when the user is under a high load and corresponding moisture formation or increased mask weight.
Aus den Unteransprüchen ergeben sich weitere Merkmale und vorteilhafte Weiterbildungen der Erfindung.Further features and advantageous developments of the invention result from the subclaims.
So ergibt sich ein weiterer Vorteil aus der Befestigung des Schläfenbandes an unmittelbar mit den Kopfbändern verbundenen Haltelaschen insoweit, als trotz der Anordnung von sechs Bändern nur eine Vierpunkt- Befestigung an der Maske, nämlich zwei Befestigungspunkte für das Kopfbandteil und gleichzeitig das Schläfenband sowie zwei Befestigungspunkte für das Nackenband, erforderlich sind. Das vereinfacht die Montage und Demontage im Zusammenhang mit der Reinigung der Atemschutzmaske .So there is a further advantage from the attachment of the temple band to holding tabs directly connected to the headbands insofar as despite Arrangement of six bands only a four-point attachment to the mask, namely two attachment points for the headband part and at the same time the temple band and two attachment points for the neck band, are required. This simplifies assembly and disassembly in connection with cleaning the respirator.
In Ausgestaltung der Erfindung sind beispielsweise das Schläfenband und das Nackenband so in Führungsschlitzen des Bandhalteteils geführt, dass das glatte, nicht elastische Nackenband den zum Kopf des Benutzers weisenden, schlecht gleitenden Schläfenbandabschnitt im Bandhalteteil überdeckt, so dass die Bänderung beim Anlegen der Maske dennoch leicht auf dem Kopfhaar gleitet, nicht an diesem zerrt und dieses nicht einklemmt . Andererseits ist die Halterung des Nacken- und des Schläfenbandes in Führungsschlitzen des Bandhalteteils fertigungstechnisch vorteilhaft und kostengünstig.In an embodiment of the invention, for example, the temple band and the neck band are guided in guide slots of the band holding part in such a way that the smooth, non-elastic neck band covers the poorly sliding temporal band section in the band holding part facing the head of the user, so that the banding is still slightly applied when the mask is put on the head hair slides, does not pull on it and does not pinch it. On the other hand, the mounting of the neck band and the temple band in guide slots of the band holding part is advantageous in terms of production technology and is inexpensive.
In vorteilhafter Weiterbildung der Erfindung sind die Haltelaschen mit seitlichen Führungsnuten versehen, um das in einer Schnalle mit Mittelsteg gehaltene Schläfenband entsprechend der Kopfgröße in der Länge verstellbar an den Haltelaschen zu befestigen.In an advantageous further development of the invention, the retaining tabs are provided with lateral guide grooves in order to fix the temple strap, which is held in a buckle with a central web, adjustable in length according to the head size on the retaining tabs.
Nach einem weiteren Merkmal der Erfindung ist an dem Bandhalteteil eine Grifflasche angeformt, deren Benutzung das Anlegen der Atemschutzmaske weiter erleichtert, weil damit die „Haubenöffnung" der Bänderung weit ist und winklig nach außen gestellt ist und außerdem ein Griffelement für den Benutzer beim Aufsetzen zur Verfügung steht.According to a further feature of the invention, a grip tab is formed on the strap holding part, the use of which further facilitates the application of the respiratory mask, because the “hood opening” of the strap is wide and angled outwards and a grip element is also available for the user when putting it on stands.

Die Bänderung umfasst ein einstückiges, durchThe strap includes a one-piece, through
Spritzgießen aus Kunststoff gefertigtes Kopfbandteil 1 mit einem mit diesem verbundenen elastischen Schläfenband 2 und einem nicht dehnbaren Nackenband 3 , dessen freie Enden in der Länge einstellbar an zwei Punkten an der Maske befestigt werden. Das Kopfbandteil 1 besteht aus einer Kopfplatte 4 mit einem Bandhalteteil 5 für das Schläfenband 2 und das Nackenband 3 und einem V-förmig geteilten, von der Kopfplatte 4 ausgehenden Kopfband 6 mit an dessen beiden Enden in einem Winkel angeformten Haltelaschen 7 zur Befestigung der Enden des in der Länge einstellbaren dehnungselastischen Schläfenbandes 2. Die freien Enden des V-förmigen Kopfbandes 6 sind mit einem and der Maske angebrachten Befestigungclip 8 (siehe Fig. 3) lösbar verbunden.Injection molding headband part 1 made of plastic with an elastic temple band 2 connected to it and a non-stretchable neck band 3, the free ends of which are adjustable in length and attached to the mask at two points. The headband part 1 consists of a head plate 4 with a band holding part 5 for the temple band 2 and the neck band 3 and a V-shaped head band 6, starting from the head plate 4, with holding straps 7 formed at both ends at an angle for fastening the ends of the Length-adjustable elastic elastic temple band 2. The free ends of the V-shaped head band 6 are detachably connected to a fastening clip 8 (see FIG. 3) attached to the mask.
Das Kopfbandteil 1 weist im Bereich der Kopfplatte 4 eine größere Stärke (1 mm) als im Bereich des Kopfbandes 6 (0,5 mm) auf und ist in sich im wesentlichen steif, jedoch unter Belastung noch so flexibel oder biegeelastisch, dass es sich an die Kopfform anpassen kann. Die dünneren Kopfbänder 6 sind hingegen weniger steif bzw. soweit flexibel, um von sich aus eine etwa der Kopfform entsprechende Wölbung auszubilden. Die Wandstärke des Kopfbandes 6 kann zu den hitzebelasteten Seitenrändern hin oder generell im Endbereich etwas größer werden, um bei Hitzeeinwirkungen eine lange Haltbarkeit zu gewährleisten. Zusammen mit dem an dem Bandhalteteil 5 und den Haltelaschen 7 angebrachten Schläfenband 2 weist ein derart ausgebildetes Kopbandteil 1 eine haubenartige Struktur auf und kann somit in Verbindung mit den gleitfreudigen, ebenen Kunststoffflächen des Kopfbandteils 1 auch von einem ungeübten Benutzer einfach und schnell, d.h. ohne besondere Übung oder Fertigkeiten, angelegt werden. Die einzelnen Teile der Bänderung können sich nicht verdrehen oder aufgrund von Reibungskräften an den Haaren zerren.The headband part 1 has a greater thickness (1 mm) in the area of the head plate 4 than in the area of the headband 6 (0.5 mm) and is essentially stiff in itself, but is still so flexible or elastic under load that it is suitable can adjust the head shape. The thinner head straps 6, on the other hand, are less stiff or flexible enough to inherently form a curvature corresponding approximately to the shape of the head. The wall thickness of the headband 6 can become somewhat larger towards the heat-stressed side edges or generally in the end region, in order to ensure a long shelf life when exposed to heat. Together with the temple band 2 attached to the band holding part 5 and the holding tabs 7, a head band part 1 designed in this way has a hood-like structure and can thus be used in conjunction with the smooth, planar ones Plastic surfaces of the headgear part 1 can also be created easily and quickly by an inexperienced user, ie without any special practice or skills. The individual parts of the harness cannot twist or pull on the hair due to frictional forces.
Das Bandhalteteil 5 verfügt über erste Führungsschlitze 9, die im wesentlichen waagerecht und parallel zueinander angeordnet und zudem so ausgerichtet sind, dass das in diesem geführte Nackenband 3 V-förmig zu denThe band holding part 5 has first guide slots 9, which are arranged essentially horizontally and parallel to one another and are also aligned such that the neck band 3 guided therein is V-shaped to the
Befestigungspunkten an der Maske (nicht dargestellt) gerichtet ist. Zwei jeweils zu den Enden der parallelen ersten Führungsschlitze 9 fluchtend und zwischen diesen angeordnete zweite Führungsschlitze 10 dienen der Aufnahme des elastischen Schläfenbandes 2. Das V-förmig nach unten verlaufende Nackenband 3 und das im wesentlichen waagerecht verlaufende Schläfenband 2 sind jeweils so durch die zugehörigen Führungsschlitze 9 bzw. 10 geführt, dass die an der Innenseite des Bandhalteteils 5 liegenden, zum Kopf des Benutzers weisenden Abschnitte des elastischen Schläfenbandes 2 von dem glatten, nicht elastischen Nackenband 3 überdeckt werden. Das heißt, die stumpfen und zudem waagerecht verlaufenden Abschnitte des Schläfenbandes 2 werden von senkrechten gleitfähigen Abschnitten des Nackenbandes 3 überdeckt, und somit stellt auch die Bandbefestigung an der Kopfplatte keinen Widerstand beim Anlegen der Atemschutzmaske dar.Attachment points on the mask (not shown) is directed. Two in each case aligned with the ends of the parallel first guide slots 9 and arranged between them, second guide slots 10 serve to accommodate the elastic temple band 2. The V-shaped neck band 3 and the substantially horizontal temple band 2 are each so through the associated guide slots 9 and 10, respectively, that the sections of the elastic temple band 2 lying on the inside of the band holding part 5 and facing the head of the user are covered by the smooth, non-elastic neck band 3. This means that the blunt and also horizontally running sections of the temple band 2 are covered by vertical, slidable sections of the neck band 3, and thus the band attachment to the head plate does not represent any resistance when the respirator mask is put on.
Die Befestigung der Enden des Schläfenbandes 2 erfolgt mit Hilfe einer in zwei seitlichen Führungsnuten 12 der jeweiligen Haltelasche 7 vor einem Querschlitz 11 lösbar arretierten Schnalle (nicht dargestellt) , um deren Mittelsteg eine Schlaufe (nicht dargestellt) des durch den Querschlitz 11 gesteckten Schläfenbandes 2 geführt ist. Die Haltelaschen 7 sind so an das Kopfband 6 angeformt, dass sie etwa parallel zu den Schläfen des Maskenträgers verlaufen und somit die vorgegebene Haubenform der Bänderung unterstützen.The ends of the temple band 2 are fastened with the aid of a buckle (not shown) which is releasably locked in two lateral guide grooves 12 of the respective retaining tab 7 in front of a transverse slot 11, around the central web of which a loop (not shown) of the temple band 2 inserted through the transverse slot 11 is guided is. The retaining tabs 7 are molded onto the headband 6 in such a way that they run approximately parallel to the temples of the mask wearer and thus support the predetermined hood shape of the strap.
Die Befestigung des Kopfbandteils 1 an der Maske erfolgt jeweils über einen in einer Ausnehmung 16 der Haltelasche 7 drehbar gelagerten Befestigungssteg 17 an einem Haltehaken 18 eines mit der Maske verbundenen Befestigungsclips 8, der über zwei entgegengesetzt zueinander federnde Rasthaken 15 in einer Scheibenrahmenöse 13 lösbar verrastet ist. Mit Hilfe der an den Enden des V-förmig verlaufenden Kopfbandes 6 angeformten Haltelaschen 7 wird somit mit zwei Befestigungspunkten (Halterhaken 18) an der Maske eine Vierpunkt-Bänderung mit Zweipunkt-Befestigung geschaffen, die einen festen Sitz der Maske und gleichzeitig deren einfache Wartung und Montage gewährleistet. Zu dem sicheren und jederzeit gasdichten Anliegen der Atemschutzmaske, und zwar auch bei körperlicher Belastung des Benutzers und bei hohem Maskengewicht, trägt in erheblichem Maße das in Schläfenhöhe des Benutzers verlaufende dehnungselastische Schläfenband 2 bei. Der hohe Tragekomfort und das leichte Anlegen der Maske ist wesentlich auf die biegeelastisch steife, gleitfreudige Ausbildung des aus Kunststoff bestehenden Kopfbandteils 1, dessen Kopfbänder und Kopfplatte zur Bildung der Haubenform jedoch eine unterschiedliche Steifigkeit aufweisen, zurückzuführen. Aus der Zeichnung ist weiter ersichtlich, dass an dem unteren Rand des Bandhalteteils 5 eine Grifflasche 14 angeformt ist. Durch deren Verwendung wird das schnelle Anlegen der Atemschutzmaske weiter erleichtert, weil der Öffnungswinkel des Bandhalteteils 5 und damit auch des elastischen Schläfenbandes 2 vergrößert wird und das Schläfenband sich somit nicht verdrehen kann und die Haare des Benutzers nicht eingeklemmt werden können und an diesen keine das Anlegen der Maske störenden Reibungskräfte wirken .The headband part 1 is attached to the mask in each case by means of a recess 16 in the retaining tab 7 rotatably mounted fastening web 17 on a retaining hook 18 of a fastening clip 8 connected to the mask, which is releasably latched in a pane frame eyelet 13 by means of two latching hooks 15 which are resiliently opposed to one another. With the help of the molded on the ends of the V-shaped headband 6 retaining tabs 7 is thus created with two attachment points (holder hooks 18) on the mask a four-point harness with two-point attachment, the firm fit of the mask and at the same time its easy maintenance and Assembly guaranteed. The stretch-elastic temple band 2, which runs at the user's temple height, makes a significant contribution to the safe and gas-tight fitting of the respiratory mask at all times, even when the user is under physical strain and with a high mask weight. The high wearing comfort and the easy application of the mask is essentially due to the flexible, stiff, slippery design of the plastic headgear part 1, the headgear and headplate of which form the hood shape but have different stiffness. It can also be seen from the drawing that a grip tab 14 is formed on the lower edge of the band holding part 5. Through their use, the rapid application of the respiratory mask is further facilitated because the opening angle of the band holding part 5 and thus also of the elastic temple band 2 is increased and the temple band cannot twist and the user's hair cannot be pinched and no application can be pinched on it frictional forces acting on the mask.
Aus den Zeichnungen geht weiter hervor, dass das Bandhalteteil 5 nach beiden Seiten durch Seitenlaschen 19 verlängert is . Dadurch wird einem Verdrehen des Schläfenbandes 2 beim Anlegen der Maske entgegengewirkt . Außerdem werden die durch das Schläfenband verursachten Reibungskräfte minimiert und die Bänderung (das Schläfenband) ist beim Anlegen der Maske entsprechend der Kopfform (Kopf mfang) ausgerichtet. Bezugs zeichenlisteFrom the drawings it can further be seen that the band holding part 5 is extended on both sides by side tabs 19. This counteracts a twisting of the temple band 2 when the mask is put on. In addition, the frictional forces caused by the temple band are minimized and the banding (the temple band) is aligned when the mask is put on according to the shape of the head.
