Description

Batteriegespeiste Kleinstablampe für * . andbedienung mit längs bewegbaren Batterieelementen in einem deren e'#i#'#ä-ektroden kraftschlüssig umfassenden und beideren i#W##4# Isolierrohr Das Patent 646 885 betrifft eine batteriegespeiste Kleinstäblampe für Einhandbedienung mit längs bewegbaren Batterieelementen in -einem deren Außenelektroden kraftschIüssig umfassenden und beiderends offenen Isolierrohr, an dem eine Kontaktfeder befestigt ist, die mit ihrem einen Ende ständig einer Batterieelektrode (Außenmantel) anliegt und mit ihrem anderen Ende mit der Glühlampenfassung als Schalter zusammenwirkt.Battery-powered miniature lamp for *. and operation with longitudinally movable battery elements in one of their e '# i #'# ä -electrodes frictionally encompassing both i # W ## 4 # insulating tube The patent 646 885 relates to a battery-powered miniature lamp for one-hand operation with longitudinally movable battery elements in one of their outer electrodes frictionally comprehensive insulating tube, open at both ends, to which a contact spring is attached, one end of which is constantly in contact with a battery electrode (outer jacket) and the other end of which interacts with the bulb socket as a switch.

Die Erfindung betrifft eine besonders vorteilhafte Ausführungsform einer derartigen Kleinstablampe und kennzeichnet sich dadurch, daß das Isolierrohr am unteren Ende teilweise, z. B. durch einen Innenringflansch, geschlossen ist, und daß in der verbleibenden öffnung ein federnd gegen den Boden der Batterie bewegbarer Druckknopf angeordnet ist. Mittels dieses Druckknopfes werden die Batterie und die Glühlampenfassung von der einen in die andere Schaltstellung, im Regelfall von der Ausschaltstellung in die Einschaltstellung bewegt. Dabei ist es von Vorteil, zwischen dem Druckknopf und der Batterie eine Schraubenfeder anzuordnen, deren Vorspannung nur so groß bemessen zu werden braucht, daß der Stirnrand des Druckknopfes ständig dem Innenringflansch des Gehäuses aufliegt, wenn auf den Druckknopf keine Kraft ausgeübt wird.The invention relates to a particularly advantageous embodiment such a miniature lamp and is characterized in that the insulating tube at the lower end partially, z. B. is closed by an inner ring flange, and that in the remaining opening a resiliently movable against the bottom of the battery Push button is arranged. The battery and the Incandescent lamp holder from one switch position to the other, usually from the Switch-off position moved to the switch-on position. It is an advantage to choose between the push button and the battery to arrange a coil spring, the preload only needs to be dimensioned so large that the front edge of the push button is constantly rests on the inner ring flange of the housing when no force is applied to the push button is exercised.

Ein Beispiel dieser Ausführungsform der Erfindung ist auf der Zeichnung veranschaulicht. Abb. i ist ein Längsschnitt durch eine Kleinstahlampe im Ausschaltzustand mit einem als Kapsel gestalteten Druckknopf. Abb. 2 veranschaulicht schematisch, teils in Ansicht, teils im Schnitt, die überführung der Kleinstablampe nach Abb. i in den Einschaltzustand durch vorübergehendes Abstützen auf einer Unterlage. Abb. 3 ist ein Längsschnitt durch die Kleinstablampe nach Abb. i im Einschaltzustand. Die Anordnung der außen am Gehäuse 31 vorgesehenen Kontak-tfeder 38, der Batterieelemente mit ihren Außenelektroden 32 bzw. 34, der Glühlampenfassung 37 und der ihr ,weiterhin zugeordneten Teile entspricht dem in den Abb. 5 und 6 des Hauptpatents Dargestellten. Der Innenringflansch am unteren Ende des Gehäuses 3 1 ist mit 5 2, der als Kapsel ausgebildete Druckknopf mit 53, sein Stirnrad mit 54 und die. zwischen dem Druckknopf 5 3 und der Außenelektrode 3 2 der Batterie liegende Schraubenfeder mit 55 bezeichnet. Im Ausschaltzustand liegt stets der Stirnrand 54 des Druckknopfes 53 dem innenringflansch52 des Gehäuses 31 auf und ihm liegt der Boden der Außenelektrode 32 der Batterie an. Drückt man, wie es, Abb. 2 erkennen läßt, das Gehäuse 3 1 der Kleinstablampe gegen eine Unterlage, dann werden durch Vermittlung des Druckknopfes 53 die Innenteile der Kleinstablampe verschoben, so daß diese in den Ausschaltzustand gelangt. Hebt man alsdann die Kleinstablampe von der Unterlage ab, dann legt sich wieder unter der Wirkung der Schraubenfeder 55 der Stirnrand 54 des Druckknopfes 53 gegen den Innenringflansch52 des Gehäuses 31.An example of this embodiment of the invention is illustrated in the drawing. Fig. I is a longitudinal section through a small steel lamp in the switched-off state with a push button designed as a capsule. Fig. 2 illustrates schematically, partly in view, partly in section, the transfer of the miniature lamp according to Fig. I into the switched-on state by temporarily supporting it on a base. Fig. 3 is a longitudinal section through the miniature lamp according to Fig. I in the switched-on state. The arrangement of the contact spring 38 provided on the outside of the housing 31, the battery elements with their outer electrodes 32 and 34, the incandescent lamp socket 37 and the parts still assigned to it corresponds to that shown in FIGS. 5 and 6 of the main patent. The inner ring flange at the lower end of the housing 3 1 is 5 2, the push button designed as a capsule with 53, its spur gear with 54 and the. Coil spring located between the push button 5 3 and the outer electrode 3 2 of the battery is denoted by 55. In the switched-off state, the end edge 54 of the push button 53 always rests on the inner ring flange 52 of the housing 31 and the bottom of the outer electrode 32 of the battery rests against it. If, as can be seen in Fig. 2, the housing 3 1 of the miniature lamp is pressed against a base, the inner parts of the miniature lamp are displaced by means of the push button 53, so that it is switched off. If the miniature lamp is then lifted from the base, the end edge 54 of the push button 53 rests against the inner ring flange 52 of the housing 31 again under the action of the helical spring 55.
