Description

Elektrische Leuchte 'mit galvanischer Batterie und verschiebbarer Abblendvorrichtung Die vorliegende Erfindung bezieht sich auf eine elektrische Leuchte mit galvanischer Batterie und verschiebbarer Abblendvorrichtung. Dabei ist es Aufgabe der Erfindung. die Leuchte möglichst -flach auszuführen, um sie bequem in der Tasche unterbringen zu können. Dies wird erfindungsgemäß durch eine besondere Ausbildung des Abblendschiebers -erreicht.Electric lamp 'with galvanic battery and sliding Dimming device The present invention relates to an electric lamp with galvanic battery and sliding screen. It is a job the invention. Make the lamp as flat as possible so that it can be carried comfortably in your pocket to be able to accommodate. According to the invention, this is achieved through a special training of the stop-down slide reached.

Bei den bisher bekannten elektrischen Leuchten mit Abblendschieber bestand dieser aus einem mit einem Schlitz versiehenon Blech, wobei über dem Schlitz ein dachförmiger, aus dem Abblendschieber hervortretender Aufbau angebracht war, welcher den horizontalen Lichtaustritt verhindert und nur einen schmalen Lichtstreifen schräg nach unten austreten läßt. Es ergab sich hierdurch die Notwendigkeit, das Gehäuse der elektrischen Leuchte um die Höhe des dachförmigen Aufbaues zu vergrößern.In the previously known electric lights with dimming slide this consisted of a sheet metal provided with a slot, with over the slot a roof-shaped structure protruding from the shutter was attached, which prevents the horizontal light emission and only a narrow strip of light can exit obliquely downwards. This made it necessary to Housing of the electric light to increase the height of the roof-shaped structure.

Auf Grund der vorliegenden Erfindung wird dieser Nachteil dadurch vermieden, daß auf einem vor die Glühlampe verschiebbaren lichtundurchlässigen Blech über dem in dem Blech befindlichen Schlitz ein diesen abdekkendes Federblech angeordnet ist, welches nach innen, z. B. in den Reflektor, federnd zurückschlägt und den Schlitz freigibt, sobald die Abblendvorrichtung vor die Glühlampe gebracht ist. Dagegen wird das Federblech über dem Schlitz an das Blech z. B. mittels einer Zwischenwand des Lampengehäuses angedrückt, wenn die Abblendvorrichtung von der Glühlampe weggezogen ist.Because of the present invention, this disadvantage is eliminated avoided that on an opaque sheet which can be displaced in front of the incandescent lamp A spring steel sheet covering the slot is arranged above the slot in the sheet metal is which inside, e.g. B. in the reflector, resiliently strikes back and the slot releases as soon as the dimming device is brought in front of the light bulb. Against it the spring plate over the slot on the plate z. B. by means of a partition of the lamp housing when the dimming device is pulled away from the bulb is.

Die Zeichnung zeigt, und zwar Abb. i in Vorderansicht und Abb.2 im Seitenschnitt ein Ausführungsbeispiel der elektrischen Leuchte nach der Erfindung.The drawing shows, namely Fig. I in front view and Fig.2 in Side section of an embodiment of the electric lamp according to the invention.

Wie :ersichtlich, ist über dem in dem Blech b angebrachten Schlitz s das Federblech f angeordnet. Dieses Federblech f schlägt nach innen, z. B. in den Reflektor r, federnd zurück und gibt den Schlitz s für den Lichtdurchtritt schräg nach unten frei, sobald das Blech b vor die Glühlampe g gebracht ist. Für die Hinundherbewegung des Bleches b dienen die Hebel hl und lt., welche um entsprechende Drehpunkte dl und d2 mittels des außen zugänglichen Bedienungsknopfes k geschwenkt w #erden und in dem Drehpunkt da mit dem Blech b verbunden sind. Verschiebt man, wie in Abb. i strichpunktiert angedeutet, das Blech b nach unten, so legt sich das Federblech i dicht an das Blech b an, welches, zwischen der Außenwanda und der Zwischenwandz geführt, nach unten gleitet. Auf diese Weise wird die Stärke der gesamten Abblendvorrichtung gegenüber den bisher bekannten Vorrichtungen auf das Äußerste verringert, da das Federblech selbstverständlich ebenfalls sehr dünn ausgeführt werden kann und der zusätzliche Platzbedarf nur der Stärke des Federbleches entspricht.As can be seen, the spring plate f is arranged above the slot s made in the plate b. This spring plate f strikes inwards, for. B. in the reflector r, resiliently back and releases the slot s for the passage of light obliquely downwards as soon as the sheet b is brought in front of the bulb g. B for the reciprocation of the sheet, the lever and serve hl lt., Which are dl about respective pivot points pivoted k and d2 by means of externally accessible control knob w #erden and since b connected in the pivot point with the sheet. If one shifts the sheet metal b downwards, as indicated by dash-dotted lines in fig. In this way, the thickness of the entire dimming device is reduced to the utmost compared to the previously known devices, since the spring plate can of course also be made very thin and the additional space requirement only corresponds to the thickness of the spring plate.
