Description

Die Erfindung geht aus von einer Leuchte nach dem Oberbegriff des Anspruchs 1.The invention relates to a lamp according to the preamble of claim 1.

Leuchten nach dem Oberbegriff des ersten Anspruchs sind beispielsweise als Tisch-,Wand- oder Decken­leuchten bekannt. Die Drehbarkeit des Standfußes wird bei bekannten Leuchten dadurch sichergestellt, daß das Deckelteil (bzw. Bodenteil) eine umlaufende Nut aufweist. Nach dem Einpassen des Deckelteils in den zylindri­schen Topf wird die Nut durch das Eindrehen von Schrauben hinterfangen, ohne in seiner Drehbarkeit dadurch beschränkt zu werden. Bei dieser Anordnung hat sich gezeigt, daß ein Verkippen und eine Schwergängigkeit bei der Drehbewegung auftreten kann.Lights according to the preamble of the first claim are known for example as table, wall or ceiling lights. The rotatability of the base is ensured in known lights in that the cover part (or base part) has a circumferential groove. After the cover part has been fitted into the cylindrical pot, the groove is backed in by screwing in screws, without the rotatability being restricted thereby. With this arrangement it has been shown that tilting and stiffness can occur during the rotary movement.

Es ist Aufgabe der vorliegenden Erfindung, eine Leuchte bereitzustellen, die leichtgängig ist und bei der kein Verkippen auftreten kann.It is an object of the present invention to provide a luminaire which is smooth-running and in which no tilting can occur.

Diese Aufgabe wird durch die kennzeichnenden Merk­male des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen finden sich in den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further advantageous configurations can be found in the subclaims.

Die Vorteile der Erfindung liegen insbesondere in der Materialeinsparung (Schrauben), der einfachen Montage und der Bedienungsfreundlichkeit.The advantages of the invention lie in particular in the saving of materials (screws), the simple assembly and the ease of use.

Die in Figur 1 und 2 gezeigte Tischleuchte aus hochtemperaturbeständigem Kunststoff enthält eine Niedervolthalogenglühlampe 1 (12 V/75 W), die in einem Reflektor 2 mit Griffkappe 3 sitzt. Der Reflektor ist in eine zentrale, kreisförmige Öff­nung eines flächenförmigen, etwa quadratischen Halteteils 4 eingelassen. Eine etwa quaderförmige Fassung 5 ist am rückwärtigen Ende des Reflektors mittels zweier Schrauben 6 befestigt. An einer Seite des Halteteils 4 ist ein Scharnier 7 ausge­bildet, das das Halteteil mit einem flächenförmigen Basisteil 8 schwenkbar (um 98°) verbindet. Basis­teil und Halteteil haben die gleiche Breite. Das Basisteil 8 sitzt vertikal auf der Oberseite eines zylindrischen Standfußes 9 und ist seitlich etwas über den Standfuß herabgezogen, der einen kleineren Durchmesser (10,5 cm) als die Breite (13 cm) des Basisteils und Halteteils aufweist. Der Standfuß 9 ist dreiteilig gegliedert in einen - auf den Kopf gestellten - zylindrischen Topf 10, an dem das Basisteil 8 ansetzt, ein als Kreisscheibe ausge­bildetes Verschlußteil 11 sowie einen auf das Ver­schlußteil aufgesetzten Überdeckel 12, dessen mit Noppen bestückter Boden die eigentliche Standfläche der Tischleuchte bildet. Die Kreisscheibe des Ver­schlußteils 11 ist in ihrem Außendurchmesser dem Innendurchmesser von Topf 10 und Überdeckel 12 angepaßt und besitzt am Außenumfang einen umlau­fenden Wulst 19, dessen Außendurchmesser form­schlüssig an Topf und Überdeckel angepaßt ist und als Anschlag beim Zusammenbau des Standfußes dient.The table lamp shown in FIGS. 1 and 2 made of high-temperature-resistant plastic contains a low-voltage halogen incandescent lamp 1 (12 V / 75 W), which is seated in a reflector 2 with a grip cap 3. The reflector is embedded in a central, circular opening in a flat, approximately square holding part 4. An approximately cuboid socket 5 is attached to the rear end of the reflector by means of two screws 6. On one side of the holding part 4, a hinge 7 is formed, which connects the holding part to a flat base part 8 so that it can pivot (by 98 °). Base part and holding part have the same width. The base part 8 sits vertically on the top of a cylindrical base 9 and is pulled down laterally slightly above the base, which has a smaller diameter (10.5 cm) than the width (13 cm) of the base part and holding part. The stand 9 is divided into three parts in a - upside down - cylindrical pot 10, on which the base part 8 attaches, a closure part 11 designed as a circular disc and an overcap 12 placed on the closure part, the base of which is equipped with knobs and forms the actual standing surface of the table lamp. The circular disc of the closure part 11 is adapted in its outer diameter to the inner diameter of the pot 10 and cover 12 and has a circumferential bead 19 on the outer circumference, the outer diameter of which is form-fitted to the pot and cover and serves as a stop during assembly of the base.

Die elektrische Stromversorgung erfolgt über ein Netzkabel 13 mit Stecker, das in den Innenraum des Überdeckels 12 geführt ist und von dort durch eine zentrale Öffnung der Kreisscheibe mit Verlänge­rungsstutzen 14 in den Innenraum des Topfes 10 gelangt. Am "Boden" 15 des Topfes ist eine Platine 16 montiert, die die für die Stromversorgung der Lampe 1 verwendeten elektrischen Bauteile 17 trägt, darunter insbesondere einen Transformator. Eine mögliche Betriebsschaltung, die die Leuchte für den Dimmerbetrieb geeignet macht, ist z.B. in der DE-OS 36 35 109 beschrieben. Über einen Kanal im Innern des Basisteils 8 werden die elektrischen Zuleitungen in das Scharnier 7 eingefädelt. An dessen Mittelstück ist ein elastisches breitflä­chiges Halteband 18 angesetzt, das sich bogenförmig bis zur Fassung 5 erstreckt. Das Halteband 18 enthält zwei Kanäle, in denen die elektrischen Zuleitungen zur Fassung geführt werden. Halteband und Fassung sind Gegenstand der Parallelanmeldung mit der Anmelde-Nr......The electrical power supply takes place via a mains cable 13 with a plug, which is led into the interior of the cover 12 and from there reaches the interior of the pot 10 through a central opening of the circular disk with extension piece 14. On the "bottom" 15 of the pot, a circuit board 16 is mounted, which carries the electrical components 17 used for the power supply of the lamp 1, including in particular a transformer. A possible operating circuit that makes the lamp suitable for dimmer operation is described, for example, in DE-OS 36 35 109. The electrical leads are threaded into the hinge 7 via a channel in the interior of the base part 8. An elastic, broad holding strap 18 is attached to the middle piece and extends in an arc shape up to the holder 5. The tether 18 contains two channels in which the electrical leads are led to the socket. The tether and socket are the subject of the parallel application with application number ......

Der Topf 10 und das Verschlußteil 11 sind mittels eines Bajonettverschlusses gegeneinander drehbar. Figur 3 zeigt einen Blick in den Innenraum des Topfes 10. Kurz unterhalb des Topfrandes 20 sind - unregelmäßig über den Umfang der Seitenwände des Topfes verteilt - sechs radial nach innen abste­hende Rippen 21 angeordnet. Sie sind jeweils 12 mm lang (entsprechend einer Bogenlänge von 14°) und ca. 2 mm breit. Die Verteilung der Rippen 21 über den Umfang ist so gewählt, daß zwei Sätze von jeweils drei Rippen, die näherungsweise (jedoch nicht exakt!) ein gleichseitiges Dreieck (mit Winkeln, die von 60° maximal um 15° abweichen) bilden, ineinander verschachtelt sind. Durch diese Anordnung wird ein optimales Gleiten zwischen Topf 10 und Verschlußteil 11 sichergestellt (s. u.). Eine der Rippen, 21a, ist mit einer nach innen verlängerten Nase 22 ausgestattet, die einen An­schlag für einen Verdrehschutz bildet. Im einzelnen beträgt der Abstand der Rippen voneinander, ausge­hend von Rippe 21a, 47° - 65° - 51° - 31° - 38° - 43°.The pot 10 and the closure part 11 can be rotated relative to one another by means of a bayonet catch. FIG. 3 shows a view into the interior of the pot 10. Shortly below the pot rim 20, six ribs 21 projecting radially inwards are arranged, irregularly distributed over the circumference of the side walls of the pot. They are each 12 mm long (corresponding to an arc length of 14 °) and approx. 2 mm wide. The distribution of the ribs 21 over the circumference is chosen so that two sets of three ribs, which approximately (but not exactly!) Form an equilateral triangle (with angles that deviate from 60 ° by a maximum of 15 °), are nested one inside the other . This arrangement ensures optimal sliding between the pot 10 and the closure part 11 (see below). One of the ribs, 21a, is equipped with an inwardly extended nose 22, which forms a stop for an anti-rotation protection. Specifically, the spacing of the ribs from one another, starting from rib 21a, is 47 ° -65 ° -51 ° -31 ° -38 ° -43 °.

Außer den Rippen 21 enthält der Topf 10 noch eine Öffnung 23 im Boden 15, durch die die elektrische Zuleitung in das Basisteil und das Scharnier 7 eingeführt werden kann. Ferner sind am Boden 15 noch Befestigungspunkte 24 für die Platine vorhan­den. Ein Teil der Seitenwand ist mit Lüftungs­schlitzen 25 zur Temperaturregulierung für die elektrischen Bauteile versehen.In addition to the ribs 21, the pot 10 also contains an opening 23 in the base 15 through which the electrical feed line can be inserted into the base part and the hinge 7. Furthermore, attachment points 24 for the board are also present on the bottom 15. Part of the side wall is provided with ventilation slots 25 for regulating the temperature of the electrical components.

Das Verschlußteil 11 ist eine Kreisscheibe 11a mit beidseitig hochgezogenen Seitenrändern, wie in Draufsicht und im Schnitt in Figur 4 dargestellt. Oberhalb des Wulstes 19 läuft außen an der Kreis­scheibe 11a eine Nut 27 um, die durch Seitenwände 28, 29 aus dem Fleisch der Kreisscheibe begrenzt ist. Den Rippen 21 des Topfes 10 sind entsprechende Aussparungen 26 in der topfseitigen Seitenwand 28 angepaßt, so daß ein formschlüssiges Aufsetzen des Verschlußteils 11 auf den Topf 10 möglich ist. Die Rippen 21 greifen dabei in die Nut 27 ein und hin­terfangen die Seitenwand 28, sobald der Topf und das Verschlußteil gegeneinander verdreht werden. Als Überdrehschutz im Zusammenwirken mit der Nase 22 wird eine Schraube 30 in eine Gewindebohrung im Bereich einer Aussparung 26a des Verschlußteils 11 eingefügt, so daß sie in die Nut 27 hineinragt. Im Zusammenwirken mit der Nase 22 wird dadurch eine Überdrehsicherung bewirkt und ein Lösen des Ver­schlußdeckels verhindert. Die Anordnung der Rippen bzw. Aussparungen ist nun so gewählt, daß in jeder Drehstellung sichergestellt ist, daß immer einer der beiden ein gleichseitiges Dreieck bildenden Sätze von drei Rippen, z.B. 21a, 21c, 21e in der Nut 27 von beiden Seitenwänden 28, 29 geführt wird. Darüber hinaus können auch weitere Rippen, z.B. 21f, diese Bedingung erfüllen. Je mehr Rippen gleichzeitig geführt werden, desto besser sind die Gleiteigenschaften beim Drehen des Standfußes. Dieses Konzept der "Dreipunktlagerung" läßt sich minimal mit vier Rippen durchführen: wenn eine der Rippen sich über einer Aussparung befindet, bilden die jeweils drei restlichen das gleitende Dreieck.The closure part 11 is a circular disc 11a with raised side edges on both sides, as in Top view and shown in section in Figure 4. Above the bead 19, a groove 27 runs around the outside of the circular disk 11a and is delimited by side walls 28, 29 made from the meat of the circular disk. Corresponding recesses 26 in the pot-side wall 28 are adapted to the ribs 21 of the pot 10, so that a form-fitting placement of the closure part 11 on the pot 10 is possible. The ribs 21 engage in the groove 27 and catch the side wall 28 as soon as the pot and the closure part are rotated against each other. As an overturn protection in cooperation with the nose 22, a screw 30 is inserted into a threaded bore in the region of a recess 26a of the closure part 11, so that it projects into the groove 27. In cooperation with the nose 22, an overturn protection is thereby effected and a loosening of the closure cover is prevented. The arrangement of the ribs or recesses is now selected so that it is ensured in each rotational position that one of the two sets of three ribs, for example 21a, 21c, 21e, forming an equilateral triangle, is guided in the groove 27 by both side walls 28, 29 becomes. In addition, other ribs, eg 21f, can also meet this requirement. The more ribs are guided at the same time, the better the sliding properties are when turning the stand. This concept of "three-point support" can be carried out minimally with four ribs: if one of the ribs is located above a recess, the three remaining ones form the sliding triangle.

Ein optimales Gleitverhalten wird bei sechs Rippen erzielt, da dann jeweils drei Rippen gleichsam entkoppelt in zwei ineinander verschachtelten Drei­ecken angeordnet werden können. Das Hinzufügen weiterer Rippen verschlechtert das Gleitverhalten wieder, da jede zusätzliche Rippe auch eine weitere Aussparung zum Einsetzen benötigt.Optimal gliding behavior is achieved with six ribs, since then three ribs each, as it were decoupled in two nested triangles can be arranged. The addition of further ribs worsens the sliding behavior again, since each additional rib also requires an additional recess for insertion.

Die Erfindung ist nicht auf das gezeigte Ausfüh­rungsbeispiel einer Leuchte beschränkt, sondern läßt sich bei einer Vielzahl von drehbaren Leuch­tengehäusen verwenden. Je nachdem, ob es sich um eine Tisch-, Wand- oder Deckenleuchte handelt, ist beispielsweise der Überdeckel mit Standnoppen oder mit einem in eine Stromschiene einsetzbaren Mitten­abgriff oder mit Bohrungen zur Befestigung an der Wand ausgestattet.The invention is not limited to the illustrated embodiment of a lamp, but can be used with a variety of rotatable lamp housings. Depending on whether it is a table, wall or ceiling lamp, for example, the cover is equipped with standing knobs or with a center tap that can be inserted into a track or with holes for fastening to the wall.
