Description

Elektrische Taschenlampe. Es sind elektrische Taschenlampen bekannt, bei welchen die Einschaltung der Lampe durch Drehen des Reflektors erfolgt. Bei dieser Anordnung dient das Metallgehäuse der Batterie, das dieselbe als Schutzhülle umgibt, als leitende Verbindung zwischen den beiden Polen und der Glühlampe. Hierdurch wird die Leistungsfähigkeit der Batterie stark beeinträchtigt, weil der Strom, besonders an den Übergängen und auch in der Hülse Widerstände zu überwinden hat, welche bedeutende Spannungsverluste zur Folge haben.Electric flashlight. Electric flashlights are known in which the lamp is switched on by turning the reflector. at this arrangement is used by the metal housing of the battery and the same as a protective cover surrounds, as a conductive connection between the two poles and the incandescent lamp. Through this Battery performance is severely affected because of the current, especially at the transitions and also in the sleeve has to overcome resistance, which is significant Result in voltage losses.

Bei der den Gegenstand der Erfindung bildenden Anordnung, bei welcher zweckmäßig eine Schutzhülse aus nichtleitendem Stoff gewählt wird, werden diese Mängel vermieden.In the arrangement forming the subject of the invention, in which expediently a protective sleeve made of non-conductive material is chosen, these will Defects avoided.

Der Kohlepol steht unmittelbar mit der Metallfassung, in welche die Lampe geschraubt wird, in leitender Verbindung. Die Glühlampe, welche in einem heb- und senkbaren Reflektorgehäuse untergebracht ist, gelangt beim Senken mit dem negativen Pol bzw. einer leitenden Verbindung zu,demsellbben in Berührung. Das Reflektorgehäuse kann entweder in einer Verschraubung oder einer zylindrischen Röhre bewegt werden nach Art der Edison- oder Swanfassungen. Um einen unbeabsichtigten Stromschluß oder Aufheben dessebben zu verhindern, legen sich gen Einkerbungen des beweglichen Reflektorgehäuses von selbst einschnappende Haltedrähtchen, welche dasselbe in der gewünschten Stellung festhalten.The carbon pole stands directly with the metal socket into which the Lamp is screwed, in conductive connection. The light bulb, which is in a lifting and lowerable reflector housing is housed, comes when lowering with the negative Pole or a conductive connection to the same in contact. The reflector housing can be moved in either a screw fitting or a cylindrical tube in the manner of Edison or Swan settings. To prevent an unintentional short circuit or To prevent lifting of the ebb, lay down against the notches in the movable reflector housing self-locking retaining wires, which the same in the desired position hold tight.

Die Abbildung zeigt eine beispielsweise Ausführungsform mit zwei Elementen im Aufriß als Schnitt dargestellt. Das Reflektorgehäuse, welches aus einem Trichter a besteht, an den sich ein Zylinder b anschließt, ist an seinem oberen Rand mit einer gegebenenfalls eingekerbten 'Wulst c versehen, so daß es sich von außen leicht anfassen und schrauben läßt; es ist in die Vergußmasse der Batterie eingelassen. Die Verschraubung von b umgibt eine zweite Verschraubung d, welche durch e mit dem positiven Pol leitend verbunden ist. Wird das Reflektorgehäuse niedergeschraubt, so berührt die Glühlampe f die Verbindung mit dem Zinkpol g und stellt Stromschluß her. Sobald das Reflektorgehäuse etwas herausgeschraubt wird, wird auch die Leitung aufgehoben und die Glühlampe außer Wirkung gesetzt. h, und lag sind die Haltedrähtchen, welche in Einkerbungen von a einschnappen und zur Feststellung des Reflektorgehäuses dienen.The figure shows an example embodiment with two elements shown in elevation as a section. The reflector housing, which consists of a funnel a to which a cylinder b adjoins, is provided on its upper edge with an optionally notched bead c so that it can be easily grasped and screwed from the outside; it is embedded in the potting compound of the battery. The screw connection of b surrounds a second screw connection d, which is conductively connected to the positive pole by e. If the reflector housing is screwed down, the incandescent lamp f touches the connection with the zinc pole g and creates a current connection. As soon as the reflector housing is unscrewed a little, the cable is also canceled and the light bulb is deactivated. h, and lag are the retaining wires that snap into notches at a and are used to hold the reflector housing in place.
