Description

Die Erfindung betrifft eine Leuchte mit einem Lampenfassungsträger, einem mindestens einen Stromleiter umgebenden Rohr und einem Halterungsteil für das Rohr, wobei das Rohr und die Aufnahmebereiche für die Rohrenden im zusammengefügten Zustand miteinander im Eingriff stehende, an den zugehörigen Bauteilen feste Kontaktstifte bzw. Kontaktbuchsen aufweisen, die konzentrisch zueinander und zur Mittelachse des Rohrs angeordnete Kontaktflächen aufweisen.The invention relates to a luminaire with a lamp holder carrier, a tube surrounding at least one current conductor and a holding part for the tube, the tube and the receiving regions for the tube ends in the assembled state having mutually engaged contact pins or contact sockets on the associated components, which have contact surfaces arranged concentrically to one another and to the central axis of the tube.

Bei einer bekannten Leuchte dieser Art (FR-A-1 215214) sind die Rohrenden ineinander eingesteckt. Eine Beweglichkeit der Rohrstücke ist damit nur um die gemeinsame Symmetrieachse der Verbindungsstellen, also um die Längsachse der Rohrstücke möglich.In a known lamp of this type (FR-A-1 215214) the tube ends are inserted into one another. Movement of the pipe sections is therefore only possible around the common axis of symmetry of the connection points, that is, around the longitudinal axis of the pipe sections.

Für Arbeitsplatzleuchten ist diese Möglichkeit in vielen Fällen nicht ausreichend.In many cases, this option is not sufficient for workplace lamps.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der als bekannt vorausgesetzten Art so auszubilden, dass ihre Rohrstücke in Abhängigkeit von deren Endausführung unterschiedliche Relativbewegungen zueinander ermöglichen. Dabei soll es möglich sein, dass die miteinander zu verbindenden Rohre an ihren benachbarten Bereichen auch völlig gleiche Durchmesser aufweisen.The object of the invention is to design a luminaire of the type known to be known in such a way that its tube pieces enable different relative movements to one another depending on their final design. It should be possible for the pipes to be connected to one another to have completely identical diameters at their adjacent areas.

Die Lösung dieser Aufgabe erfolgt dadurch, dass die Enden von zwei Rohren mittels eines Verbindungsstücks verbindbar sind, das zwei zueinander parallele Kanäle zur Aufnahme und zum klemmenden Umgreifen der Rohrenden besitzt, welche elektrische Kontaktstifte bzw. Kontaktbuchsen zum Anschluss an die zugehörigen Gegenstücke in den Rohrenden aufweisen.This object is achieved in that the ends of two pipes can be connected by means of a connecting piece which has two mutually parallel channels for receiving and for gripping around the pipe ends, which have electrical contact pins or contact sockets for connection to the associated counterparts in the pipe ends .

Gemäss einem weiteren Merkmal der Erfindung besteht das klemmende Verbindungsstück aus zwei plattenförmigen Halbschalen, die jeweils zwei annähernd hälftige Aufnahmekanäle aufweisen und mittels einer Verbindungsschraube zusammenspannbar sind.According to a further feature of the invention, the clamping connecting piece consists of two plate-shaped half-shells, each of which has two approximately half receiving channels and can be clamped together by means of a connecting screw.

Es hat sich ferner als zweckmässig erwiesen, dass in dem Verbindungsstück eine Rastfeder angeordnet ist, welche gleichzeitig in Rastnuten beider eingesetzter Rohrenden eingreift.It has also proven to be expedient for a catch spring to be arranged in the connecting piece, which spring engages in the catch grooves of both pipe ends used at the same time.

Es wird ferner vorgeschlagen, dass am Ende der beiden Aufnahmekanäle ein Verbindungsstück mit zwei stirnseitig in die Kanäle ragenden Kontaktstiften bzw. Kontaktbuchsen eingesetzt ist, wobei die Kontakte dieses elektrischen Kontaktstücks elektrisch leitend miteinander verbunden sind.It is further proposed that at the end of the two receiving channels a connecting piece with two contact pins or contact sockets projecting into the channels at the end is inserted, the contacts of this electrical contact piece being connected to one another in an electrically conductive manner.

Schliesslich wird erfindungsgemäss noch vorgeschlagen, dass die Rohre an einem Ende oder beiden Enden winklig abgebogen sind.Finally, it is also proposed according to the invention that the tubes are bent at an angle at one end or both ends.

Nachstehend werden bevorzugte Ausführungsformen der Erfindung anhand der Zeichnung im einzelnen beschrieben. Es zeigen:

In Fig. 1 ist eine Gelenkleuchte dargestellt. Diese Gelenkleuchte besitzt ein Fussteil 18, in dem ein Halterungsteil 2 für ein Rohr 1 angeordnet ist. Das Rohr 1 kann unterschiedliche Form aufweisen. Es kann beispielsweise winklig abgebogen sein, wie im unteren Bereich von Fig. 1, ferner kann es an beiden Enden gekröpft sein, wie im oberen Bereich von Fig. 1, es kann jedoch auch gradlinig ausgebildet sein. Da es nur auf den grundsätzlichen Aufbau des Rohrs 1 ankommt, sind sämtliche Rohre mit den gleichen Bezugszeichen bezeichnet und nur durch unterschiedliche Hochstriche voneinander unterschieden.In Fig. 1, an articulated lamp is shown. This articulated lamp has a foot part 18 in which a holding part 2 for a tube 1 is arranged. The tube 1 can have different shapes. For example, it can be bent at an angle, as in the lower region of FIG. 1, furthermore it can be cranked at both ends, as in the upper region of FIG. 1, but it can also be designed in a straight line. Since it is only a matter of the basic structure of the tube 1, all the tubes are identified by the same reference numerals and are distinguished from one another only by different prime lines.

Das obere Rohr 1" greift mit seinem abgewinkelten Bereich ebenfalls in ein Halterungsteil 2 ein, das in einen als Reflektorteil ausgebildeten Fassungsträger 19 eingesetzt ist.The angled area of the upper tube 1 ″ also engages in a holding part 2 which is inserted into a mount carrier 19 designed as a reflector part.

Das Halterungsteil 2 ist in Fig. 2 genauer dargestellt. Es besteht aus zwei halbschalenartigen Teilen 20 und 21 mit im zusammengesetzten Zustand zu einer Durchgangsbohrung sich ergänzenden Kanälen 22 und 23. In die aus den beiden Kanälen 22 und 23 gebildete Durchgangsbohrung ragt eine Rastfeder 24 ein. Die beiden Halbschalen nehmen die Kontaktbuchsen 25 zwischen sich auf und werden von der Schraube 26 zusammengespannt. Ähnlich wie das Halterungsteil 2 ist das Verbindungsstück 10 ausgebildet, das zwei zueinander parallele Kanäle 11 und 12 aufweist, die durch das Zusammenfügen von zwei plattenförmigen Halbschalen 13 und 14 gebildet werden. Die beiden plattenförmigen Halbschalen 13 und 14 werden durch die Verbindungsschrauben 15 zusammengespannt. Eine Rastfeder 16 erstreckt sich mit jeweils einem Schenkel in jeden der beiden Kanäle 11 und 12.The holding part 2 is shown in more detail in FIG. 2. It consists of two half-shell-like parts 20 and 21 with channels 22 and 23 which complement each other in the assembled state to form a through hole. A detent spring 24 projects into the through hole formed from the two channels 22 and 23. The two half-shells hold the contact sockets 25 between them and are clamped together by the screw 26. Similar to the holder part 2, the connecting piece 10 is formed, which has two mutually parallel channels 11 and 12, which are formed by the joining of two plate-shaped half-shells 13 and 14. The two plate-shaped half-shells 13 and 14 are clamped together by the connecting screws 15. A detent spring 16 extends with one leg in each of the two channels 11 and 12.

Am Ende der beiden Kanäle ist ein elektrisches Verbindungsstück 17 zwischen die Halbschalen 13 und 14 eingelegt, das zwei Kontaktbuchsen 27 und 28 enthält, die elektrisch miteinander verbunden sind. Mit 30 sind die Muttern für die Verbindungsschrauben 15 bezeichnet.At the end of the two channels, an electrical connector 17 is inserted between the half-shells 13 and 14, which contains two contact sockets 27 and 28, which are electrically connected to one another. With 30 the nuts for the connecting screws 15 are designated.

Aus den Fig. 4 bis 7 ist die Endausbildung der Rohre 1 bzw. der zugehörigen Gegenstücke entnehmbar, die entweder in Fassungsteilen, Halterungsteilen, Verbindungsrohren oder anderen Rohren angeordnet sein können.4 to 7, the final formation of the tubes 1 and the associated counterparts is ent acceptable, which can either be arranged in socket parts, mounting parts, connecting tubes or other tubes.

Ein erstes Steckerteil 31 besitzt in seinem Zentrum einen Kontaktstift32, der mit der elektrischen Zuleitung 33 verbunden ist. Der Kontaktstift 32 wird von einer Hülse 34 umgriffen. Ein entsprechendes Gegenstück, das als Buchse 35 ausgebildet ist, ist im gegenüberliegenden Rohrende enthalten (vergleiche Fig. 6). Diese Buchse 35 ist elektrisch mit dem im Rohrinneren geführten Kabel 36 verbunden. Im zusammengesteckten Zustand ergibt sich die in Fig. 7 dargestellte Einschubposition. In dieser Einschubposition liegt die Rastfeder 9 in der Rastnut 8 des Endstücks des Rohrs 1.A first plug part 31 has a contact pin 32 in its center, which is connected to the electrical feed line 33. The contact pin 32 is encompassed by a sleeve 34. A corresponding counterpart, which is designed as a bush 35, is contained in the opposite pipe end (see FIG. 6). This socket 35 is electrically connected to the cable 36 guided inside the tube. When inserted, the insertion position shown in FIG. 7 results. In this insertion position, the detent spring 9 lies in the detent groove 8 of the end piece of the tube 1.

Bei der Ausführungsform gemäss Fig. 8 und 9 ist ein zentraler Kontaktstift 41 vorgesehen, der mit einem buchsenartigen Gegenstück 42 korrespondiert. Die Teile 41 und 42 übertragen den Strom aus den Leitern 43 und 44.In the embodiment according to FIGS. 8 and 9, a central contact pin 41 is provided, which corresponds to a socket-like counterpart 42. The parts 41 and 42 transmit the current from the conductors 43 and 44.

Zwei weitere Stromleiter 45 und 46 enden an zwei metallischen, konzentrisch angeordneten Buchsen 47 und 48, die aneinander anliegen. Auch bei dieser Anordnung von Rohren, die mehrere Leiter enthalten, ist eine Verdrehbarkeit der miteinander im Eingriff stehenden Rohre oder Bauteile um die Rohrachse sichergestellt.Two further current conductors 45 and 46 end at two metallic, concentrically arranged sockets 47 and 48 which abut one another. With this arrangement of pipes, which contain several conductors, the mutually engaging pipes or components can be rotated about the pipe axis.

Es sind auch andere Steckerausführungen denkbar, bei denen die Kontaktflächen jeweils konzentrisch zur Rohrachse liegen. Dabei ist es unerheblich, welche der beiden zusammengehörigen Steckerteile in welchem der angeschlossenen Bauteile liegen. Die Buchsen und die Kontaktstifte können isoliert in entsprechend ausgebildeten Trägerkörpern aus gespritztem Kunststoff angeordnet sein.Other connector designs are also conceivable in which the contact surfaces are each concentric to the tube axis. It is irrelevant which of the two associated connector parts are in which of the connected components. The sockets and the contact pins can be arranged insulated in appropriately designed carrier bodies made of injection-molded plastic.
