Description

Vorliegende Erfindung bezieht sich auf tragbare elektrische Lampen nach Patent 293882 und betrifft eine Lampe dieser Art, bei welcher der Mantel des die Lichtquelle einschließenden Hohlzylinders mit einem Fortsatz versehen ist, der bei der Drehung des Mantels mit einem nachgiebigen mittleren und zwei festen seitlichen Anschlägen und außerdem mit einem im anschließenden Teile des Lampengehäuses befindlichen Schleifkontakt in Berührung treten kann, derart, daß die Stellung des Mantels mit Bezug auf die im Hohlzylinder befindlichen seitlichen und unteren Öffnungen mit Sicherheit festgelegt und bei der Öffnung der Lichtöffnungen gleichzeitig das elektrische Licht eingeschaltet werden kann, welches alsdann bei entsp'rechender Drehung des Mantels wieder erlischt.The present invention relates to patent portable electric lamps 293882 and relates to a lamp of this type in which the jacket of the enclosing the light source Hollow cylinder is provided with an extension which, when the jacket rotates, with a flexible middle and two fixed side stops and also with one in the adjoining part of the Lamp housing located sliding contact can come into contact, such that the Position of the jacket in relation to the lateral and lower ones located in the hollow cylinder Openings determined with certainty and at the same time when opening the light openings the electric light can be switched on, which then with corresponding Rotation of the jacket goes out again.

Die Lampe besteht aus einem Gehäuse α zur Aufnahme der Batterie δ; in das Gehäuse ist der Scheinwerfer c eingebaut. An letzteren. schließt sich ein Hohlzylinder d (Fig. 7 und 8) an, der zur Aufnahme der Lichtquelle e (der' Deutlichkeit halber punktiert gezeichnet) dient. Diese ist in der Achse des Hohlzylinders mittels des Armes e' so angeordnet, daß sie ihre Strahlen nach hinten auf den Scheinwerfer c, nach vorn, nach beiden Seiten und nach unten möglichst gleichmäßig und kräftig aussendet.The lamp consists of a housing α to accommodate the battery δ; The headlight c is built into the housing. On the latter. adjoins a hollow cylinder d (FIGS. 7 and 8), which serves to accommodate the light source e (shown in dotted lines for the sake of clarity). This is arranged in the axis of the hollow cylinder by means of the arm e ' so that it emits its rays backwards onto the headlight c, forwards, to both sides and downwards as evenly and powerfully as possible.

Gegenüber der Lichtquelle e befinden sich in dem Hohlzylinder d zwei seitliche Öffnungen / und eine untere Öffnung g. Auf dem Zylinder d sitzt drehbar ein Außenzylinder h (Fig. 6) mit ζλνεΐ einander gegenüberliegenden Öffnungen i. Diese sind etwa ebenso groß ■ wie die Öffnungen / des Zylinders d und können mit diesen durch Drehen des Außenzylinders zur Deckung gebracht werden.Opposite the light source e there are two lateral openings / and a lower opening g in the hollow cylinder d. An outer cylinder h (FIG. 6) with ζλνεΐ opposing openings i is seated rotatably on the cylinder d. These are about the same size as the openings / of the cylinder d and can be brought into congruence with them by turning the outer cylinder.

Der Außenzylinder h trägt einen Fortsatz k, The outer cylinder h has an extension k,

Claims

which in the illustrated embodiment has the shape of a curved arm. This arm engages with play in a slot / of the housing a, which has the shape of a quarter circle. The arm is arranged at about 45 ^° to the tendon connecting the centers of the openings i.

A flexible stop is provided in the interior of the housing approximately in the middle of the slot I. This is set up in such a way that although it offers a noticeable obstacle to the movement of the arm k , it does not prevent this further movement. In the present exemplary embodiment, the flexible stop consists of a resilient contact in (FIGS. 9 and 10). This contact forms part of a metal strip t which is arranged inside the lamp housing, specifically on its front wall, concentric to the slot / by means of the insulating pieces u . On the strip f, two further contacts m ' and m "are formed, which over the ends of the slot / lie.

In the embodiment of the strip t according to FIGS. 9 and 10, the movement of the arm k is limited by the ends of the slot I or by special stops ν. In the embodiment of the strip t according to FIG. 11, the contacts m ' and m "are designed in such a way that they form stops for the contact arm k .

The metal strip t is in a conductive connection through the wire w with the battery b and the arm k with the one lamp wire χ through the cylinders h and d. The other lamp wire y is connected directly to the battery b .

A cover n, which is provided with a rotatable smaller cover 0 , serves to cover the front opening of the lamp. The cover η is carried by side arms p ; these are held by pins q which are inserted into slots r of the. Arms ρ intervene.

In order not to hinder the exit of the lateral rays, the arms p have recesses 5 of any shape.

The mode of operation of the lamp is as follows: In the position of the parts shown in FIG. 1, the arm k is in engagement with the central contact m. So the light source is switched on. Even so, no light beam can emerge from the lamp because all the apertures are closed. Namely, the front cover η rests against the cylinder d , the small cover 0 is folded down, and none of the openings / and g is released.

If you want to let a weak bundle of rays exit to the front, open the small cover 0 (Fig. 2). If a free exit of the rays to the front is desired, the cover η is first pulled forward (FIG. 8) and then folded down (FIG. 5).

If the light source is to be switched off, the outer cylinder h only needs to be rotated slightly to the right or left. The arm it then reaches either the position k ' or k " (FIGS. 10 and 11), ie it is not in contact with any of the contacts.

The lateral exit of the rays is achieved by turning the outer cylinder h in the direction of the arrow Z "until the arm k comes into engagement with the contact m". Here, the openings / and i of the two cylinders are congruent, while the light source e is switched on at the same time.

The exit of the rays downwards is achieved by turning the outer cylinder h in the direction of the arrow Z 'until the arm k comes into engagement with the contact m'. Here, one of the openings i is aligned with the opening g , while the light source e is switched on at the same time.
The arm k and its stops can of course also be designed in a different manner. ■ ■ "'. ■ ■'

Godfather τ-An saying:

Portable electric lamp according to patent 293882, characterized in that the jacket (h) is provided with a contact arm (k) which reaches into the interior of the housing and which, when the jacket is rotated, is provided with a flexible middle (m) and two fixed lateral fm ' , m "), contacts located in the adjacent parts' of the housing can come into contact, in such a way that the position of the jacket with respect to the lateral and lower openings in the hollow cylinder is determined with certainty and, when the light opening is opened, the electric light is simultaneously determined is switched on, which then goes out again when the jacket is rotated back in intermediate positions.
