Description

Die Gesichtsschutzmaske dient dazu (speziell beim Lichtbogenschweißen), einen Schutz für das Gesicht gegen spritzende Metall- und Schlacketeilchen zu bieten. The face mask is used (especially for arc welding), to provide protection for the face against splashing metal and slag particles.

Der zur Zeit gebräuchliche Schutz besteht aus einem Hartpappeschirm, versehen mit einem Fenster (Filterscheibe). Er wird von dem Schweißer beim Schweißen mit der Hand vor das Gesicht gehalten. Außerdem sind noch zwei weitere Gesichtsschutze bekannt, die aber weniger oder gar nicht im Gebrauch sind. Bei einem wird die Filterscheibe pneumatisch, beim anderen mittels Bowdenzuges geöffnet oder geschlossen. The protection currently in use consists of a hard cardboard screen, provided with a window (filter disc). He is held by the welder while welding held with the hand in front of the face. There are also two other face shields known, but they are less or not at all in use. One of them is the filter disc pneumatically, with the other open or closed by means of a Bowden cable.

Beide Prinzipien bergen jedoch die erhöhte Gefahr von Gesundheitsschädigung in sich, da in beiden Fällen die Betätigung des Mechanismus ganz oder teilweise mit dem Mund erfolgt und hierbei die beim Schweißen entstehenden Dämpfe durch den Mund strömen können.However, both principles harbor an increased risk of damage to health in itself, since in both cases the operation of the mechanism in whole or in part takes place with the mouth and the vapors produced during welding through the Mouth can flow.

Es wird nunmehr vorgeschlagen, um die Hand für andere notwendige Verrichtungen, z. B. zum Festhalten auf dem Gerüstfrei zu halten und dem unnötigen Einatmen von Giftstoffen vorzubeugen, die bekannten Schutzschirme durch eine Gesichtsschutzmaske zu ersetzen, welche vor dem Gesicht unverschiebbar befestigt wird. Offnen und Schließen der Filterscheibe wird mittels einer Vorrichtung durch das Heben und Senken des Kopfes erzielt. It is now suggested to hand necessary for others Performances, e.g. B. to hold on to the scaffolding and the unnecessary To prevent inhalation of toxins, the well-known protective shields through a face mask to replace, which is fixed in front of the face. Open and close the filter disc is raised and lowered by means of a device Head scored.

Ein Beispiel der technischen Lösung der an die Gesichtsschutzmaske gestellten Anforderung stellt die schematische Darstellung (Abb. I) dar. An example of the technical solution of the face mask The schematic representation (Fig. I) represents the requirement.

Im Rahmen R, der schräg zur Senkrechten in Augenhöhe der Gesichtsschutzmaske M vertikal verschiebbar gelagert ist, befindet sich die Filterscheibe F. Durch das Verbindungsgestänge V ist der Rahmen beweglich mit dem Betätigungshebel B, welcher seinen Drehpunkt unmittelbar an der Gesichtsschutzmaske selbst hat, verbunden. Um das Schweißen in allen Lagen, z. B. über dem Kopf oder in gebückter Stellung, zu ermöglichen, ist der Betätigungshebel durch den Gleithebel G verlängert. Dieser Gleithebel ist am unteren Ende des Betätigungshebels schwenkbar gelagert. Er muß der jeweiligen Schweißlage angepaßt und durch eine Klemmschraube festgestellt werden. Da die Vorrichtung bei Betätigung unter Spannung der Schraubenzugfeder S, die bei S, an dem Gestänge V und bei S2 an der Gesichtsschutzmaske M befestigt ist, kommt, bleibt der Gleithebel in ständiger Berührung mit dem nur durch die Kleidungsstücke getrennten Brustbein. In frame R, the one at an angle to the vertical at eye level of the face mask M is mounted so that it can be moved vertically, there is the filter disk F. Linkage V is the frame movable with the operating lever B, which has its pivot point directly on the face mask itself. Around welding in all positions, e.g. B. over the head or in a stooped position, too enable, the operating lever is extended by the sliding lever G. This Sliding lever is pivotably mounted at the lower end of the actuating lever. He must adapted to the respective welding position and fixed by a clamping screw. Since the device when actuated under tension of the helical tension spring S, which at S, which is attached to the linkage V and to the face mask M at S2, comes, the sliding lever remains in constant contact with the only through the garments separated sternum.

Das Öffnen oder Schließen der Filterscheibe erfolgt demgemäß durch Heben bzw. Senken des Kopfes.The filter disk is opened or closed accordingly Raising or lowering the head.

Abb. 2 und 3 zeigen die Funktion der Vorrichtung. Fig. 2 and 3 show the function of the device.
