Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Im Haupt-Patent geschieht die Lösung des zur Sicherung der gegenseitigen Lage von Boden und oberem Fassungstheil der Glühlampe in ein Loch des Bodens eingeschnappten Stiftes durch Ausheben desselben mittelst eines Schlüssels, indem der Stift an seinem oberen Theil eine Einschnürung besitzt, an welche sich ein durch den Schlüssel bewegbarer Querstift anlegt.In the main patent, the solution to secure the mutual position of The bottom and upper part of the bulb holder are snapped into a hole in the bottom By lifting it out with a key by placing the pin on its upper part Part has a constriction to which a transverse pin, movable by the key, is attached applies.

An Stelle dieser Einrichtung soll die im nachfolgenden beschriebene und auf beiliegender Zeichnung dargestellte einfachere Anordnung dienen.Instead of this device, the one described below and on the enclosed Simplified arrangement shown in the drawing.

Die Befestigung der den Stift b tragenden Feder c geschieht auf der inneren Fläche des oberen Fassungstheiles D und ist dementsprechend der Stift (Körner) b auch bedeutend kurzer. Dagegen ist die Feder c mit ihrem freien Ende so lang ausgebildet, dafs dasselbe durch ein Loch der Wandung etwas nach aufsen hervorragt, so dafs auf diese Weise die ■ Wiederauslösung des Stiftes b einfach durch Empordrücken der Feder c geschehen kann.The fastening of the spring c carrying the pin b takes place on the inner surface of the upper socket part D and accordingly the pin (center point) b is also significantly shorter. On the other hand, the free end of the spring c is so long that it protrudes slightly outwards through a hole in the wall, so that in this way the pin b can be released again simply by pushing the spring c upwards.

Der Vortheil dieser Einrichtung liegt in der aufserordentlichen Einfachheit derselben und darin, dafs sie einen Schlüssel vollständig entbehrlich macht.The advantage of this arrangement lies in its extraordinary simplicity and in that it makes a key completely dispensable.

Giebt man dem Körner einen dreikantigen Querschnitt, derart, dafs eine Schärfe desselben in der Richtung liegt, in welcher sich jener beim Aufschrauben bewegt, so gelingt, wenn derselbe etwa nur 1 bis 1,5 mm lang ist, das Lösen bereits durch einen etwas kräftigen Ruck beim Losdrehen der Lampe. In diesem Fall fällt also die Ausbildung der Feder c mit nach aufsen verlängertem freien Ende ganz weg. Trotzdem wird auch bei dieser einfachsten Anordnung ein Selbstlockern der Lampe nicht eintreten.If the grain is given a triangular cross-section in such a way that it is sharp in the direction in which it moves when it is screwed on, then, if it is only about 1 to 1.5 mm long, the loosening is already a little stronger Jerk when loosening the lamp. In this case, the design of the spring c with an outwardly extended free end is completely eliminated. Nevertheless, even with this simplest arrangement, the lamp will not loosen itself.
