Abstract

The invention relates to a protective shield for work carried out with evolution of smoke or gas, the protective shield being double-walled and the outer wall being provided with openings through which the smoke or the gas enters the suction space connected to a suction line.

Description

Schutzschild für Arbeiten bei Rauch- und/oder GasentwicklungProtective shield for work in the event of smoke and / or gas development

Die vorliegende Erfindung betrifft einen Schutzschild für Arbeiten bei Rauch- und/oder Gasentwicklung vorzugsweise beim Schweißen, der in seiner Wandung ein Schauschutzglas aufweist.The present invention relates to a protective shield for work in the case of smoke and / or gas development, preferably during welding, in its wall has a protective glass.

Derartige Schutz schilde werden insbesondere beim Schweißen benötigt um den Schweißer gegen Funkenflug zu schützen. Obendrein treten jedoch noch bei derartigen Arbeiten Rauch und Gase auf, die nicht nur störend, sondern auch gesundheitsschädlich sind.Such protective shields are particularly needed when welding to protect the welder against flying sparks. On top of that, however, still join Such work produces smoke and gases, which are not only annoying but also harmful to health are.

Es sind bereits Schutzschilde für Schweißer mit zugeordneter vor dem Schauglas angebrachter Absaugvorrichtungen bekannt, die die beim Arbeiten entstehenden Gase vom unmittelbaren Bereich der Schweißstelle absaugen. Dies hat jedoch noch den Nachteil, daß die Absaugung nur auf einen begrenzten Bereich beschränkt ist und damit die Güte der Schweißung gefährdet.There are already protective shields for welders assigned in front of the Sight glass attached suction devices known that arise when working Extract gases from the immediate area of the welding point. However, this still has the disadvantage that the suction is limited to a limited area and thus the quality of the weld is endangered.

Aus der CH-PS 563 153 ist fernerhin ein Schweißschild bekannt, bei dem unmittelbar unterhalb des Schauglases eine Vorwölbung mit aufgesetztem Saugraum vorgesehen ist, deren obere Abschlußwand siebartig gelocht ist. beim Abzug der von der Schweißstelle stammenden Gase streichen diesc.die nach unten in die Sieblöcher einzusaugen sind, zuerst sichtbehindernd vor dem Schauglas vorbei, wobei fernerhin der Nachteil auftritt, daß Rauch und gesundheitsschdliche GaseGaseunten und seitliche um den Schild herum zum Kopf des Schweißers vordringen können.From CH-PS 563 153 a welding shield is also known at immediately below the sight glass there is a bulge with an attached suction chamber is provided, the upper end wall is perforated like a sieve. when deducting from The gases coming from the welding point sweep these down into the sieve holes are to be sucked in, first past the sight glass, obstructing the view, and furthermore the disadvantage occurs that smoke and noxious gasesgases below and side can get around the shield to the welder's head.

Der Erfindung liegt die Aufgabe zugrunde, einen Schutzschild für Arbeiten bei Rauch- und/oder Gasentwicklung zu schaffen, der so ausgestaltet ist, daß der Rauch und/oder die Gase nicht vor das Schauglas gelangen können und auch nicht bis zu der Person hinter dem Schauglas vordringen können.The invention is based on the object of a protective shield for work to create in the event of smoke and / or gas development, designed like this is that the smoke and / or gases cannot reach the sight glass and nor can they penetrate to the person behind the sight glass.

Ausgehend von einem Schutzschild der eingangs genannten Art, wird zur Lösung dieser Aufgabe vorgeschlagen, daß der Schild doppelwandig als Saugraum ausgeführt ist,daß die Außenwand, im wesentlichen über ihre ganze Ausdehnung verteilt, Saugschlitze oder -löcher aufweist, durch welche Rauch und/oder Gas in den an die Saugleitung angeschlossenen Saugraum einsaugbar sind, und daß die Innenwand zum Rauch- und/oder Gasstau als Umrandung vorsteht.Starting from a protective shield of the type mentioned above, proposed to solve this problem that the shield double-walled as a suction chamber it is designed that the outer wall, essentially distributed over its entire extent, Has suction slots or holes through which smoke and / or gas enters the Suction line connected suction chamber can be sucked in, and that the inner wall to Smoke and / or gas jam protrudes as a border.

Mit dem erfindungsgemäßen Schutzschild wird nicht nur das Schauglas wirksam vor Sichtbehinderungen bewahrt, sondern es wird hierdurch eine unsichtbare Trennwand geschaffen, die Rauch und/oder Gase über einen bestimmten Bereich daran hindern, zur arbeitenden Person vorzudringen.With the protective shield according to the invention not only the sight glass effectively protected from visual obstructions, but it becomes an invisible one Partition wall is created that adapts smoke and / or gases over a certain area prevent access to the working person.

Im folgenden wird die Erfindung anhand der Zeichnung näher erläutert, in der ein vorteilhaftes Ausführungsbeispiel der Erfindung dargestellt ist. Es zeigen: Figur 1 eine Vorderansicht und Figur 2 einen Schnitt durch den erfindungsgemäßen Schild.In the following the invention is explained in more detail with reference to the drawing, in which an advantageous embodiment of the invention is shown. Show it: Figure 1 is a front view and Figure 2 is a section through the invention Sign.

Der erfindungsge:äße Schutzschild ist in Richtung des Schweißers hin konkav ausgestaltet und weist zwei Wandungen 1, 2 auf, die im wesentlichen über ihre ganze Ausdehnung einen Hohlraum 3 begrenzen, der den Saugraum bildet. In den so gebildeten Saugraum 3 können durch eine beliebige Anzahl von Löchern oder Schlitzen 4 entsprechender Größe,die beliebig über die vordere Wandung 1 verteilt sein können und auch um die Schauglasumrandung herum angeordnet sein können, die ab, zuführenden Gase von der Bearbeitungsstelle her gelangen.The erfindungsge: äße protective shield is in the direction of the welder designed concave and has two walls 1, 2, which essentially limit their entire extent a cavity 3, which forms the suction space. In the So formed suction space 3 can be through any number of holes or slots 4 of a corresponding size, which can be distributed as desired over the front wall 1 and can also be arranged around the sight glass border, which from feeding Gases come from the processing point.

Zweckmäßigerweise ist an der Innenwand 2,in deren Fensteröffnung das Schauschutzglas 6 eingesetzt ist, ein Absaugstutzen 5 angeordnet, der nach unten abgewickelt sein kann, und mittels entsprechender Schnaub- oder Steckelemente mit dem Saugschlauch 7 verbunden ist, dessen Ansatz gleichzeitig den Handgriff bildet.Appropriately is on the inner wall 2, in the window opening Protective glass 6 is inserted, a suction nozzle 5 is arranged, which is down can be handled, and by means of appropriate screw or plug elements with the suction hose 7 is connected, the approach of which forms the handle at the same time.

Beim Einsatz des erfindungsgemäßen Schutzschildes ist es möglich, ohneunnötignaheandLeschweißstelle herangehen zu müssen, bei freier Sicht und ohne Behinderung durch Rauch oder Gase zu arbeiten.When using the protective shield according to the invention, it is possible Without having to go unnecessarily close to the welding point, with a clear view and without Obstruction by smoke or gases to work.

Zum Rauch- und/oder Gasstau ist die Innenwand derart ausgebildet, daß sie als Umrandung vorsteht.For smoke and / or gas accumulation, the inner wall is designed in such a way that that it protrudes as a border.
