Description

Die Erfindung betrifft eine Schutzanzug mit einem Reißverschluß als Durchlaßöffnung nach dem Oberbegriff des Anspruchs 1.The invention relates to a protective suit with a zipper as a passage opening according to the preamble of claim 1.

Um den Körper eines Menschen vor schädlichen Einwirkungen bei seinem Einsatz in vergifteter oder sonst mit Schadstoffen angereicherter Atmosphäre zu schützen, sind dafür geeignete Schutzanzüge oder Hauben bekannt, welche gas- und/oder wasserdicht um den gesamten Körper angelegt werden können. Sie sind so zugeschnitten, daß selbst Atemschutzgerät und/oder dazugehörige Atemschutzmasken unter dem Schutzanzug getragen werden können. Zum Einstieg in diesen Schutzanzug muß eine genügend weite Öffnung geschaffen werden, wozu beispielsweise ein Reißverschluß in einer dazu günstigen Wegführung eingearbeitet ist. Um einen bequemen Einstieg und nach beendetem Einsatz einen möglichst einfachen Ausstieg zu ermöglichen, bei dem der Anzugträger nicht mit äußeren, verschmutzten Oberflächen in Berührung kommt, ist der Verlauf des Reißverschlusses so vorzusehen, daß eine möglichst ungehinderte Entfaltung des geöffneten Schutzanzuges verwirklicht wird. Dies ist insbesondere dann notwendig, wenn weitere Geräte am Körper unterhalb des Schutzanzuges getragen werden müssen, wie dies zum Beispiel für den Einsatz unter schwerem Atemschutz bei Feuerwehrleuten, Tauchern, Bergleuten oder auch für Piloten notwendig ist, die einen ABC-Schutzanzug benötigen.In order to protect the body of a person from harmful effects when used in a poisoned or otherwise enriched atmosphere, suitable protective suits or hoods are known which can be put on the entire body in a gas-tight and / or watertight manner. They are tailored so that even respirators and / or associated respirators can be worn under the protective suit. To get into this protective suit, a sufficiently wide opening must be created, for which purpose, for example, a zipper is incorporated in a convenient route. In order to allow easy entry and, after use, the easiest possible exit, in which the suit wearer does not come into contact with external, dirty surfaces, the course of the zipper must be provided in such a way that the opened protective suit is unfolded as freely as possible. This is particularly necessary if additional devices have to be worn on the body underneath the protective suit, as is necessary for firefighters, divers, miners or pilots who need an ABC protective suit, for example under heavy breathing protection.

Bei dem dazu erforderlichen Verlauf des Reißverschlusses ergeben sich außer geraden Abschnitten dann oft auch gekrümmt um Körperbereiche verlaufende Umwegstrecken.In addition to straight sections, the zipper course required for this often results in detours that are curved around body areas.

Ein derartiger Schutzanzug ist aus der DE-Z: "Gebrauchsanleitung Gasschutzanzug 600 PF, Nr. 2536.3, 1. Ausgabe Januar 1980, Drägerwerk AG, Lübeck", bekannt, und wird darüber hinaus in der DE-Z: "Drägerheft, Nr. 312, Seite 5 bis 13, September/ Dezember 1978", beschrieben.Such a protective suit is known from DE-Z: "Instructions for Use Gas Protective Suit 600 PF, No. 2536.3, 1st Edition January 1980, Drägerwerk AG, Lübeck", and is also described in DE-Z: "Dräger Review, No. 312 , Pages 5 to 13, September / December 1978 ".

Der bekannte Schutzanzug zeigt einen Reißverschluß, der ausgehend von der rechten Beinseite über die Brust zur Schulter und von dort aus quer über die gesamte Breite der Kopfhaube geführt ist. Andere Linienführungen bei ähnlichen Schutzanzügen verlaufen quer an der Vorderseite des Anzugs und sind zur Schulter bis hin zu einem rückwärtigen Teilbereich geführt. Besondere Schwierigkeiten bereitet die Betätigung von Reißverschlüssen an solchen Abschnitten, wo sie nicht gestreckt, sondern auf einer Umwegstrecke gekrümmt verlaufen. Dort muß der Schieber unmittelbar von Hand verschoben werden. Für vom Anzugträger nicht erreichbare Stellen muß er also eine weitere Person zur Hilfestellung hinzuziehen. Während des Einsatzes können jedoch Notsituationen auftreten, bei denen ein schnelles Öffnen beispielsweise im Kopfbereich des Schutzanzuges erforderlich wird. Ein solcher Notfall kann dadurch eintreten, daß im Bereich der Atemschutzmaske eine Sitzkorrektur erfolgen muß oder ein schnelles Ablegen der Atemschutzmaske notwendig wird, z.B. bei plötzlich auftretender Übelkeit. Solche Notfälle können aber auch dann entstehen, wenn der Anzugträger durch eine Irritation im Gesichtsbereich an einer sorgfältigen Ausübung seiner Tätigkeit gehindert ist. Er ist dann bestrebt, diese Irritation zu beseitigen oder auch die durchzuführende Korrektur des Maskensitzes so schnell wie möglich zu verwirklichen, wobei er leicht in Panik geraten kann, wenn die Befreiung des Kopfbereiches aus dem Schutzanzug nur umständlich oder mit fremder Hilfe durchzuführen ist, die nicht sofort zur Verfügung steht. Andere Bereiche, zu denen der Anzugträger möglichst schnell Zugang haben muß; ohne daß der Reißverschluß auf aufwendige Art und Weise geöffnet werden muß, sind in der Nähe des am Rücken getragenen Atemschutzgerätes zu suchen.The well-known protective suit shows a zipper, which runs from the right side of the leg over the chest to the shoulder and from there across the entire width of the hood. Other lines with similar protective suits run across the front of the suit and run from the shoulder to a rear section. The operation of zippers on those sections is particularly difficult where they are not stretched but rather curved on a detour. There the slide must be moved directly by hand. For places not reachable by the suit wearer, he has to call in another person to help. However, emergency situations may arise during use, in which a quick opening is necessary, for example in the head area of the protective suit. Such an emergency can occur in that a seat correction must be carried out in the area of the respirator or that the respirator must be removed quickly, e.g. if you suddenly experience nausea. However, such emergencies can also arise if the suit wearer is prevented from performing his job carefully due to irritation in the face area. He then endeavors to remove this irritation or to implement the correction of the mask fit as quickly as possible, whereby he can easily panic if the removal of the head area from the protective suit is difficult or with outside help, which is not possible is immediately available. Other areas to which the suit wearer must have access as quickly as possible; without the zipper having to be opened in a complex manner, are to be found near the breathing apparatus worn on the back.

Aus der US-A 2 177 585 ist ein Reißverschluß bekannt, der entlang seiner Streckenführung verschiebbare Klammern besitzt. Die Klammern sind untereinander mit einem Zugseil verbunden, indem jede Klammer eine das Zuggerät festklemmende Krampe aufweist. Mit Hilfe des Zugseils sollen beim Schließen des Reißverschlusses die anfänglich aufgereihten Klammern in feste Abstände zueinander gebracht werden. Ein öffnen des Reißverschlusses mit dem Zugseil ist wegen dessen Krampenbefestigung nicht möglich.From US-A 2 177 585 a zipper is known which has clamps which can be moved along its route. The brackets are connected to each other with a pull rope, in that each bracket has a clamp that clamps the pulling device. With the help of the pull rope, the initially lined up clips should be placed at fixed distances from each other when the zipper is closed. Opening the zipper with the pull rope is not possible because of its staple attachment.

In der weiteren bekannten US-A 2 908 057 ist ein flexibles Zumittel in Form eines Seils oder einer leichten Kette an dem Schieber eines Reißverschlusses vorgesehen. Das Seil verläuft frei zwischen Schieber und einem mit der Hand leicht ergreifbaren Clip, der beispielsweise an geeigneter Stelle eines Kleidungsstückes befestigt werden kann.In the further known US-A 2 908 057 a flexible means in the form of a rope or a light chain is provided on the slide of a zipper. The rope runs freely between the slider and a clip that is easy to grasp by hand and can be attached to a suitable item of clothing, for example.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, einen Schutzanzug der genannten Art so zu verbessern daß besonders in Notsituationen die Durchlaßöffnung im Bereich ihrer Umwegstrecke von dem Anzugträger von bequem erreichbaren Stellen aus leicht geöffnet werden kann, wobei unabhängig von dem Zuschnitt und der Lage der Umwegstrecke das Öffnen durch eine einhändige Zugbewegung in beliebiger körpergerechter Richtung erfolgen kann.The present invention is therefore based on the object of improving a protective suit of the type mentioned so that, particularly in emergency situations, the passage opening in the region of its detour can be easily opened by the suit wearer from easily accessible locations, regardless of the cut and the position of the detour the opening can be done by a one-handed pulling movement in any body-appropriate direction.

Die Lösung der Aufgabe erfolgt bei einem Schutzanzug der genannten Art dadurch, daß ein flexibles Zugmittel an dem Schieber angreift und in den als Zugmittelführungen ausgebildeten Klemmstücken lose geführt ist.The problem is solved in a protective suit of the type mentioned in that a flexible traction means acts on the slide and is loosely guided in the clamping pieces designed as traction means guides.

Die mit der Erfindung erzielten Vorteile liegen im wesentlichen darin, daß nunmehr die Umwegstrecke, die nicht notwendigerweise mit der Hauptzugrichtung des Reißverschlusses der übrigen Durchlaßöffnung zusammenfallen muß, dennoch durch eine einzige Zugbewegung schnell und vollständig geöffnet werden kann. Nach Eröffnung der Umwegstrecke ist ein Zugang zum freigelegten Körperteil des Trägers oder zu einem Geräteteil möglich, ohne daß ein aufwendiges Öffnen des übrigen Anzugs erforderlich wäre. Es wird eine einfache Fernbetätigung des Reißverschlußschiebers ermöglicht, wenn dieser bei geschlossenem Reißverschluß vom Anzugträger nicht unmittelbar erreichbar ist, und dank der Führung für das Zugmittel sogar über einen gekrümmten Verlauf und in beliebiger Zugrichtung.The advantages achieved by the invention are essentially that now the detour route, which does not necessarily have to coincide with the main pulling direction of the zipper of the other passage opening, can nevertheless be opened quickly and completely by a single pulling movement. After opening the detour, access to the exposed body part of the wearer or to a device part is possible without having to open the rest of the suit. A simple remote operation of the zipper slide is made possible if it is not directly accessible from the suit wearer when the zipper is closed, and thanks to the guide for the traction means even over a curved course and in any direction of pull.

Eine derartige Lösung ist in gleicher Weise auch bei Hüllen anwendbar, die den Körper nur teilweise einschließen, wie z.B. Kopf-Schulter-Hauben, oder in ähnlichen Fällen.Such a solution can also be used in the same way for covers which only partially enclose the body, such as Head and shoulders, or in similar cases.

Das flexible Zugmittel, z.B. ein Zugseil, läuft in der Zugmittelführung und bestimmt somit die Länge der Umwegstrecke. Die Zugmittelführung sorgt dafür, daß auch bei Betätigung des Zugseils in einer Schrägzugrichtung dennoch die Führung des Schiebers entlang der Umwegstrecke erfolgt.The flexible traction device, e.g. a traction rope runs in the traction device guide and thus determines the length of the detour route. The traction means ensures that even when the pull rope is actuated in an oblique pull direction, the slide is guided along the detour route.

Die Zugmittelführung kann aus mehreren einzelnen, entlang der Umwegstrecke positionierten Stütz- und Führungsstellen in Form von Ösen oder auch aus einer ununterbrochenen geschlitzten Kulissenführung bestehen, in der das Zugseil aufgenommen ist.The traction means guide can consist of a plurality of individual support and guide points positioned along the detour route in the form of eyelets or also of an uninterrupted slotted link guide in which the traction cable is received.

Bei einer Anordnung von mehreren Zugmittelführungen entlang der Umwegstrecke wird die in Öffnungsrichtung endständige Zugmittelführung feststellbar und die übrigen verschiebbar ausgebildet. Bei geschlossenem Reißverschluß können die verschiebbaren Zugmittelführungen beliebig nach Gesichtspunkten der Zweckmäßigkeit entlang der Umwegstrecke positioniert werden, wobei lediglich die endständige Zugmittelführung an einer geeigneten Stelle des Reißverschlusses am Ende der Umwegstrecke festgestellt werden kann. Bei geschlossenem Reißverschluß legen die Zugmittelführungen den Verlauf des Zugseils entlang der Umwegstrecke fest. Beim Öffnen des Reißverschlusses werden die verschiebbar angeordneten Zugmittelführungen von dem Reißverschlußschieber mitgeschleppt, bis sie die festgestellte Zugmittelführung erreichen. Soll späterhin der Reißverschluß über die Umwegstrecke hinaus geöffnet werden, kann die festgestellte Zugmittelführung gelöst und der Reißverschlußschieber weiter entlang des Reißverschlusses gezogen werden.In the case of an arrangement of a plurality of traction device guides along the detour route, the traction device guide which is terminal in the opening direction is ascertainable and the others are designed to be movable. When the zipper is closed, the displaceable traction means guides can be positioned as desired along the detour route from the point of view of expediency, only the terminal traction device guide being able to be determined at a suitable point on the zipper at the end of the detour route. When the zipper is closed, the traction device guides determine the course of the traction rope along the detour route. When the zipper is opened, the displaceably arranged traction device guides are dragged along by the zipper slide until they reach the determined traction device guide. If the zipper is later to be opened beyond the detour, the traction device guide can be released and the zipper slide pulled further along the zipper.

Das Schließen des Reißverschlusses erfolgt nach herkömmlicher Art, wobei dann entlang der Umwegstrecke die verschiebbaren Zugmittelführungen positioniert und die Endständige festgestellt werden muß.The zipper is closed in a conventional manner, the displaceable traction means guides then having to be positioned along the detour route and the end position determined.

Eine besonders vorteilhafte Ausführungsform der endständigen Zugmittelführung kann dadurch verwirklicht werden, daß diese mit einer in Öffnungsrichtung des Schiebers gleitenden Sperrklinke versehen ist. Eine derartige Sperrklinke wird unter Schrägzug des Zugseils in Sperrichtung belastet, wodurch deren Verschiebung in Richtung zur Umwegstrecke verhindert wird, sie kann jedoch durch den auflaufenden Schieber in Löserichtung leicht mitgenommen werden. Nach dem Öffnen einer mehr oder weniger kleinen Durchtrittsöffnung längs der Umwegstrecke kann dann der Reißverschluß vollends auf dem sonst üblichen Weg geöffnet werden.A particularly advantageous embodiment of the terminal traction means guide can be realized in that it is provided with a pawl sliding in the opening direction of the slide. Such a pawl is loaded by pulling the traction cable obliquely in the reverse direction, thereby preventing its displacement in the direction of the detour route, but it can easily be taken along in the release direction by the slider which runs up. After opening a more or less small passage opening along the detour route, the zipper can then be opened completely in the usual way.

Eine weitere vorteilhafte Ausbildung der feststellbaren Zugmittelführung besteht darin, daß sie mit einem Rastschieber versehen ist, dessen Rastung durch die vom Zugseil mitgeschleppten Schieber bzw. Zugmittelführungen lösbar ist. Dadurch wird die Zugmittelführung mit Hilfe einer Sperre festgehalten, die beispielsweise zwischen die Zähne des Reißverschlusses eingreift. Sie kann dadurch wieder gelöst werden, indem die mitgeschleppten Zugmittelführungen oder auch der Reißverschlußschieber selbst auf ein Betätigungselement des Rastschiebers auflaufen oder dieses auch übergreifen und so die festgestellte Zugmittelführung entrasten.A further advantageous embodiment of the ascertainable traction means guide is that it is provided with a latching slide, the latching of which can be released by the slider or traction means guides carried by the pull rope. As a result, the traction device guide is held in place with the aid of a lock which, for example, engages between the teeth of the zipper. It can be released again by the traction means guides carried along or also the zipper slide itself running onto an actuating element of the latching slide or also engaging over it and thus unlatching the determined traction means guide.

Eine weitere Erleichterung in der Handhabung ergibt sich, wenn die Umwegstrecke das eine Ende eines doppelseitig öffenbaren Reißverschlusses ist. Dadurch wird erreicht, daß die Umwegstrecke ein nur in Notfällen zu öffnender Durchlaß ist, wobei der vollständige Ausstieg aus dem Schutzanzug durch das Öffnen des übrigen leicht zugänglichen Reißverschlußteiles erfolgen kann.A further simplification in handling results when the detour is the one end of a zipper that can be opened on both sides. This ensures that the detour is a passage that can only be opened in emergencies, and the complete exit from the protective suit can be done by opening the other easily accessible zipper part.

Ein Ausführungsbeispiel der Erfindung wird anhand der schematischen Zeichnung dargestellt und im folgenden näher erläutert.An embodiment of the invention is illustrated by the schematic drawing and explained in more detail below.

Auf der gegenüberliegenden Seite der Bahn (4) ist die Sperrklinke (13) durch die Feder (14) an die Zähne (5) gedrückt. Dabei bildet die Sperrklinke (13) an ihrem Berührungspunkt mit den Zähnen (5) einen in Öffnungsrichtung (dargestellt durch den Pfeil (17)) spitzen Winkel.The lockable traction device guide (7) is shown in more detail in Fig. 3. It carries on one side of the web (4) the eyelet (8) shown in the sectional view, through the channel (16) of which the pull rope (9), not shown, is guided. On the opposite side of the track (4), the pawl (13) is pressed against the teeth (5) by the spring (14). The pawl (13) forms an acute angle in the opening direction (represented by the arrow (17)) at its point of contact with the teeth (5).

Die Zugmittelführung (7) kann somit in der Öffnungsrichtung (17) mit schleppender Sperrklinke (13) gleiten. Eine Verstellung in entgegengesetzter Richtung ist nur möglich, wenn die Sperrklinke durch Druck auf ihr Betätigungsende (13) von den Zähnen (5) abgehoben ist.The traction means guide (7) can thus slide in the opening direction (17) with a trailing pawl (13). An adjustment in opposite Direction is only possible if the pawl is lifted off the teeth (5) by pressing its actuating end (13).

Die gleitende Befestigung ist bei den Zugmittelführungen (6, 7) ähnlich wie beim Schieber (11) dadurch erreicht, daß sie unter den Hinterschnitt der einzelnen Zähne (5) greifen.The sliding attachment is achieved in the traction device guides (6, 7) similar to the slide (11) in that they reach under the undercut of the individual teeth (5).
