Abstract

The welding shield (1) is characterized in that the darkened protective window can be pushed into an upper position by the user's chin.

Description

Bei den mechanischen Kopfschweißschirmen muß der ganze Schirm nach oben bzw. nach unten geklappt werden. Dies geschieht entweder mit den Händen oder mittels heftiger Kopfbewegungen.In the case of the mechanical head welding shields, the entire shield must be replaced can be folded up or down. This happens either with the Hands or violent head movements.

Das Problem dabei ist, daß wenn man viele einzelne Schweißpunkte anbrin­ gen muß, daß man nie die Hände frei hat zum hoch- bzw. runterklappen. Wenn man den Schirm mit heftigen Kopfbewegungen hoch- bzw. runter­ klappen will, verliert man leicht die Orientierung wieder, an welcher Stelle man zu schweißen hat.The problem with this is that if you attach a lot of individual welding spots You must never have your hands free to fold up or down. If you look up or down the screen with violent head movements want to work, you can easily lose your bearings at which point you have to weld.

Im Gegensatz dazu wird von der Erfindung das Schutzfenster durch Kinn­ druck nach belieben nach oben geschoben. Mittels Federkraft fällt das Schutzfenster wieder in seine Ausgangsposition zurück.In contrast, the invention provides the protective window through chin Push the pressure up at will. This is done by spring force Protective window back to its starting position.

Der große Vorteil dabei ist, daß man zügig schweißen kann, ohne die Hände vom Werkstück zu nehmen, was für Punktschweißen unerläßlich ist, da man kurze Wechselzeiten zwischen "sehen" und "schweißen" hat.The big advantage is that you can weld quickly without the hands to remove from the workpiece, which is essential for spot welding, since one has short changing times between "seeing" and "welding".

Zusätzlich läßt sich das Schutzfenster durch stärkeren Kinndruck weiter nach oben schieben, wodurch es einrastet und solange eine freie Sicht gewährt, bis erneuter stärkerer Kinndruck das Schutzfenster wieder schließt. In addition, the protective window can be further reduced by increasing the child pressure slide up, which will snap it into place and provide a clear view until the child pressure closes again.

Die (1) stellt einen normalen Schweißschirm dar, der mit einem Kopfgurt auf dem Kopf befestigt werden kann. Dieser ist mit einem Hebemechanismus (2) zum heben der Schutzglashalterung (3), die mit den Federn (4)-(7) fixiert ist, ausgestattet. Die (8) stellt den verstellbaren Kinngurt dar, der wenn nach unten gedrückt wird, die beiden kreuzförmig angeordneten Hebel (9) und (10) über die Drehpunkte (11) und (12) nach oben drückt. Da diese wieder­ um mittels Verbindungsstücke (13) und (14) an der Schutzglashalterung (3) befestigt sind, wird die Schutzglashalterung (3) nach oben geschoben und gibt somit den ungehinderten Blick auf das Arbeitsfeld frei. Durch zurücknehmen des Kinndrucks, fallen die kreuzförmig angeordneten Hebel in Ihre Ausgangsposition zurück und schieben somit die Schutzglashalterung wieder nach unten.The ( 1 ) represents a normal welding umbrella that can be attached to the head with a head strap. This is equipped with a lifting mechanism ( 2 ) for lifting the protective glass holder ( 3 ), which is fixed with the springs ( 4 ) - ( 7 ). The ( 8 ) represents the adjustable chin strap, which, when pressed down, presses the two cross-shaped levers ( 9 ) and ( 10 ) above the pivot points ( 11 ) and ( 12 ). Since these are again fastened to the protective glass holder ( 3 ) by means of connecting pieces ( 13 ) and ( 14 ), the protective glass holder ( 3 ) is pushed upwards and thus gives an unobstructed view of the working area. By lowering the child pressure, the cross-shaped levers fall back into their starting position and thus push the protective glass holder down again.

Will man das Schutzglas länger obenbehalten, kann dies durch stärkeren Kinndruck erreicht werden. Der stärkere Kinndruck bewirkt, daß die Schutz­ glashalterung weiter nach oben geschoben wird, so daß der Haltestift (15) im Ein/Ausrastmechanismus (16) einrastet. Bei erneutem stärkeren Kinndruck rastet der Haltestift (15) wieder aus und das Sichtfenster schließt sich wieder. If you want to keep the protective glass on top for a longer time, this can be achieved by using stronger child pressure. The stronger child pressure causes the protective glass holder to be pushed further upwards so that the retaining pin ( 15 ) engages in the on / off mechanism ( 16 ). If the child pressure is stronger again, the holding pin ( 15 ) will snap out again and the window will close again.
