Definitions
- the invention relates to a lamp, in particular to an indicator lamp with one or two-sided light emission. Such lights are e.g. used as emergency lights.
- the luminaire to which the invention relates is also referred to as a profile luminaire because it has a frame which is composed of profile pieces, the profile pieces being grooves for receiving at least one permeable wall element, e.g. have a sheet of glass.
- a corresponding frame with the features of the preamble of claim 1 is known from DE-U-8905560.
- the invention is therefore based on the object to improve a lamp with the features of the preamble of claim 1 in such a way that the translucent wall element can be removed more easily and with a smaller space requirement and the lamp can also be mounted in a wall niche, for example.
- the frame of such a lamp consists of four frame parts designed as profile pieces, which touch in bearing points of corner connecting devices, which are arranged at all eight corners of the cuboid lamp.
- the frame parts are held in the respective bearing point by spring force.
- a glass pane is held in a groove in the frame along the entire circumference.
- To open the lamp two opposite frame parts are pulled apart slightly while overcoming the spring force until they snap into the second bearing point. Due to the position of the bearing points, the distance between the opposing first frame parts as well as that between the second frame parts arranged perpendicular to it is increased in this process, so that the glass pane is released on all sides.
- FIG. 1 shows a housing 10 of a luminaire according to the invention, which has a light exit pane on a front side as a translucent wall element 1.1.
- the disc is held in a circumferential groove 13 (see FIG. 2) in a frame composed of four frame parts 2.1, 2.2. Corner areas of the frame are covered by corner caps 9, which can be square or round as required.
- Figure 2 shows a section through the lamp, which is mounted in a recess of a wall 12.
- the luminaire contains a lamp 11, a translucent wall element 1.1 and an opaque wall element 1.2 designed as a mounting base plate.
- First frame parts 2.1 with grooves 13 are also shown. Components essential to the invention which are arranged in the corner regions of the housing (cf. FIGS. 3 to 6) cannot be seen in FIG. 2.
- Figures 3 and 4 are to be considered in connection, since Figure 3 shows a closed state of the housing frame and Figure 4 shows an open state.
- a pane 1.1 is shown in the section of the lamp illustrated, which in the closed state is held on all sides in a groove in top and bottom first frame parts 2.1 and left and right second frame parts 2.2, of which only one of the frame parts 2.2 can be seen in FIGS. 3 and 4.
- Corner connecting devices 3 are arranged in each of the corner areas, each with a first connecting part 6 and a second connecting part 5.
- the first connecting part 6 is firmly connected to a first frame part 2.1; the second connecting part 5 is firmly connected to the second frame part 2.2.
- the connecting parts 5, 6 can snap into one another in a first bearing 7.1 or in a second bearing 7.2. In the closed state, the parts 5, 6 snap into one another in the first bearing 7.1.
- the bearing points 7.1, 7.2 are not only rest points, but also allow the parts 5, 6 to rotate or tilt, which makes it possible to set each corner
- each corner parts 8 are shown, which have a hook 8.2, in which a tension spring 4 is suspended.
- the corner part 8 also serves to hold the frame parts 7.1, 7.2 at a right angle. This is achieved by a support edge or surface 8.1 (see FIG. 6) on the corner part 8 on which a second frame part 2.2 rests in the closed state.
- the corner part 8 can form a structural unit with the first connecting part 6, since both parts are firmly connected to a first frame part 2.1.
- Figures 5 and 6 show the corner area of the housing in an enlarged view and without a glass pane 1.1. It can be seen in particular from FIG.
- the desired change in position of the first frame parts 2.1 is achieved by a distance b between the bearing points 7.1, 7.2, for example in the vertical direction, and a change in position the second frame parts 2.2 by a distance a of the bearing points 7.1 and 7.2 in, for example, the horizontal direction.
- the corner connection devices 3 are arranged in all eight corner areas of the lamp. Since the bearing points 7.1, 7.2 allow a small rotation or tilting movement, the housing 10 can also be brought into an open state only on one side, that is to say either on the front or the back, so that only one wall element 1.1 or 1.2 is released .
- a mounting plate for quick installation can be used as an opaque wall element 1.2 on the rear side.
- this mounting plate on which, for example, the connection terminals, the illuminant and a ballast are located, can be installed and installed.
- the luminaire housing can then be snapped onto the mounting plate in the easiest way when it is opened.

Abstract
Description
Die Erfindung bezieht sich auf eine Leuchte, insbesondere auf eine Hinweisleuchte mit ein- oder zweiseitigem Lichtaustritt. Solche Leuchten werden z.B. als Notleuchten verwendet.The invention relates to a lamp, in particular to an indicator lamp with one or two-sided light emission. Such lights are e.g. used as emergency lights.
Die Leuchte, auf die sich die Erfindung bezieht, wird auch als Profilleuchte bezeichnet, weil sie einen Rahmen aufweist, der aus Profilstücken zusammengesetzt ist, wobei die Profilstücke Nuten zur Aufnahme wenigstens eines durchlässigen Wandelements, z.B. eine Glasscheibe, haben. Ein entsprechender Rahmen mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der DE-U-8905560 bekannt. Bei einem solchen vorbekannten Rahmen ist es nicht mehr notwendig, um beispielsweise ein darin enthaltenes Leuchtmittel, wie eine Glüh- oder Leuchtstofflampe, austauschen zu können, wenigstens eines der Profilstücke des Rahmens durch Lösen oder Entfernen von Schrauben wegzunehmen, damit die Glasscheibe entfernt werden kann. Statt dessen wird lediglich ein Rahmenteil soweit gelockert und geschwenkt, daß die Scheibe ohne Beeinträchtigung der Stabilität des Gesamtgehäuses herausgezogen werden kann.The luminaire to which the invention relates is also referred to as a profile luminaire because it has a frame which is composed of profile pieces, the profile pieces being grooves for receiving at least one permeable wall element, e.g. have a sheet of glass. A corresponding frame with the features of the preamble of claim 1 is known from DE-U-8905560. In the case of such a known frame, it is no longer necessary, for example in order to be able to replace an illuminant contained therein, such as an incandescent or fluorescent lamp, to remove at least one of the profile pieces of the frame by loosening or removing screws so that the glass pane can be removed. Instead, only a frame part is loosened and pivoted so far that the pane can be pulled out without affecting the stability of the overall housing.
Bei dem vorbekannten Gehäuserahmen ist allerdings weiterhin von Nachteil, daß die Glasscheibe noch seitlich zum Rahmen aus den Nuten in den Rahmenteilen herausgezogen werden muß, so daß beispielsweise seitlich neben dem Rahmen ausreichend Raum vorhanden sein muß.In the case of the known housing frame, however, it is still disadvantageous that the glass pane has to be pulled out laterally of the frame from the grooves in the frame parts, so that, for example, there must be sufficient space to the side of the frame.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Leuchte mit den Merkmalen des Oberbegriffs des Anspruchs 1 dahingehend zu verbessern, daß das lichtdurchlässige Wandelement einfacher und mit geringerem Raumbedarf entnehmbar ist und die Leuchte beispielsweise auch in einer Wandnische montierbar ist.The invention is therefore based on the object to improve a lamp with the features of the preamble of claim 1 in such a way that the translucent wall element can be removed more easily and with a smaller space requirement and the lamp can also be mounted in a wall niche, for example.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.
Der Rahmen einer solchen Leuchte besteht aus vier als Profilstücke ausgebildeten Rahmenteilen, die sich in Lagerstellen von Eckverbindungseinrichtungen, die an allen acht Ecken der quaderförmigen Leuchte angeordnet sind, berühren. Es gibt jeweils eine Lagerstelle für einen geöffneten und einen geschlossenen Zustand. Die Rahmenteile werden durch Federkraft in der jeweiligen Lagerstelle gehalten. Eine Glasscheibe wird am gesamten Umfang in einer Nut des Rahmens gehalten. Zum Öffnen der Leuchte werden zwei gegenüberliegende Rahmenteile unter Überwindung der Federkraft etwas auseinandergezogen bis sie in der zweiten Lagerstelle einrasten. Bedingt durch die Lage der Lagerstellen wird bei diesem Vorgang sowohl der Abstand zwischen den gegenüberliegenden ersten Rahmenteilen, als auch der zwischen den senkrecht dazu angeordneten zweiten Rahmenteilen vergrößert, so daß die Glasscheibe allseits freigegeben wird.The frame of such a lamp consists of four frame parts designed as profile pieces, which touch in bearing points of corner connecting devices, which are arranged at all eight corners of the cuboid lamp. There is a storage location for an open and a closed state. The frame parts are held in the respective bearing point by spring force. A glass pane is held in a groove in the frame along the entire circumference. To open the lamp, two opposite frame parts are pulled apart slightly while overcoming the spring force until they snap into the second bearing point. Due to the position of the bearing points, the distance between the opposing first frame parts as well as that between the second frame parts arranged perpendicular to it is increased in this process, so that the glass pane is released on all sides.
Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels weiter erläutert. Es ist zu beachten, daß es sich nicht um alle Einzelheiten zeigende Konstruktionszeichnungen, sondern um Prinzipskizzen handelt.The invention is explained below with reference to an embodiment shown in the drawings. It should be noted that these are not construction drawings showing all the details, but sketches of the principle.

Figur 1 zeigt ein Gehäuse 10 einer erfindungsgemäßen Leuchte, die auf einer Vorderseite als lichtdurchlässiges Wandelement 1.1 eine Lichtaustrittsscheibe aufweist. Die Scheibe wird in einer umlaufenden Nut 13 (vergl. Figur 2) in einem aus vier Rahmenteilen 2.1, 2.2 zusammengesetzten Rahmen gehalten. Eckbereiche des Rahmens sind durch Eckkappen 9 abgedeckt, die je nach Bedarf eckig oder rund ausgeführt sein können.FIG. 1 shows a
Figur 2 zeigt einen Schnitt durch die Leuchte, die in einer Nische einer Wand 12 montiert ist. Die Leuchte enthält ein Leuchtmittel 11, ein lichtdurchlässiges Wandelement 1.1 und ein als Montagegrundplatte ausgeführtes lichtundurchlässiges Wandelement 1.2. Es sind außerdem erste Rahmenteile 2.1 mit Nuten 13 dargestellt. Erfindungswesentliche Komponenten, die in den Eckbereichen des Gehäuses angeordnet sind (vgl. Figur 3 bis 6) sind in Figur 2 nicht zu sehen.Figure 2 shows a section through the lamp, which is mounted in a recess of a
Die Figuren 3 und 4 sind in Zusammenhang zu betrachten, da Figur 3 einen geschlossenen Zustand des Gehäuserahmens und Figur 4 einen geöffneten Zustand zeigt. In dem dargestellten Ausschnitt der Leuchte ist eine Scheibe 1.1 gezeigt, die im geschlossenen Zustand allseitig in einer Nut in oben und unten befindlichen ersten Rahmenteilen 2.1 und linken und rechten zweiten Rahmenteilen 2.2 gehalten wird, von denen in den Figuren 3 und 4 lediglich eines der Rahmenteile 2.2 zu sehen ist. In den Eckbereichen sind jeweils Eckverbindungseinrichtungen 3 angeordnet, mit jeweils einem ersten Verbindungsteil 6 und einem zweiten Verbindungsteil 5. Das erste Verbindungsteil 6 ist fest mit einem ersten Rahmenteil 2.1 verbunden; das zweite Verbindungsteil 5 ist fest mit dem zweiten Rahmenteil 2.2 verbunden. Die Verbindungsteile 5, 6 können in einer ersten Lagerstelle 7.1 oder in einer zweiten Lagerstelle 7.2 ineinanderrasten. Im geschlossenen Zustand rasten die Teile 5, 6 in der ersten Lagerstelle 7.1 ineinander. Die Lagerstellen 7.1, 7.2 sind nicht nur Raststellen, sondern lassen auch eine Dreh- oder Kippbewegung der Teile 5, 6 zu, wodurch es möglich ist, jeden Eckbereich einzeln in einen geöffneten oder geschlossenen Zustand zu versetzen.Figures 3 and 4 are to be considered in connection, since Figure 3 shows a closed state of the housing frame and Figure 4 shows an open state. A pane 1.1 is shown in the section of the lamp illustrated, which in the closed state is held on all sides in a groove in top and bottom first frame parts 2.1 and left and right second frame parts 2.2, of which only one of the frame parts 2.2 can be seen in FIGS. 3 and 4.
Die für einen Zusammenhalt der Rahmenteile 7.1, 7.2 erforderliche Kraft wird durch Zugfedern 4 aufgebracht. In den Figuren 3 bis 6 sind jeweils Eckteile 8 dargestellt, die einen Haken 8.2 haben, in den eine Zugfeder 4 eingehängt ist. Das Eckteil 8 dient außerdem dazu, die Rahmenteile 7.1, 7.2 im rechten Winkel zu halten. Dies wird durch eine Auflagekante oder -fläche 8.1 (vgl. Figur 6) am Eckteil 8 erreicht, an der ein zweiter Rahmenteil 2.2 im geschlossenen Zustand aufliegt. Das Eckteil 8 kann mit dem ersten Verbindungsteil 6 eine konstruktive Einheit bilden, da beide Teile mit einem ersten Rahmenteil 2.1 fest verbunden sind. Die Figuren 5 und 6 zeigen den Eckbereich des Gehäuses in einer vergrößerten Darstellung und ohne Glasscheibe 1.1. Insbesondere aus Figur 6 ist ersichtlich, daß die angestrebte Positionsänderung der ersten Rahmenteile 2.1 durch einen Abstand b der Lagerstellen 7.1, 7.2 in z.B. vertikaler Richtung erreicht wird, und eine Positionsänderung der zweiten Rahmenteile 2.2 durch einen Abstand a der Lagerstellen 7.1 und 7.2 in z.B. horizontaler Richtung.The force required to hold the frame parts 7.1, 7.2 together is applied by
Die Eckverbindungseinrichtungen 3 sind in allen acht Eckbereichen der Leuchte angeordnet. Da die Lagerstellen 7.1, 7.2 eine kleine Dreh- oder Kippbewegung zulassen, kann das Gehäuse 10 auch nur auf einer Seite, also entweder auf der Vorder- oder der Rückseite in einen geöffneten Zustand gebracht werden, so daß nur ein Wandelement 1.1 oder 1.2 freigegeben wird.The
Im Fall einer einseitigen Leuchte, also nur mit einem Lichtaustritt auf einer Vorderseite, kann auf der Rückseite ein Montageblech für eine Schnellmontage als lichtundurchlässiges Wandelement 1.2 eingesetzt werden. Bei der Installation der Leuchte kann zunächst dieses Montageblech, auf dem sich z.B. die Anschlußklemmen, das Leuchtmittel und ein Vorschaltgerät befinden, montiert und installiert werden. Anschließend kann auf einfachste Weise das Leuchtengehäuse im auf der Rückseite aufgeklappten Zustand auf das Montageblech aufgeschnappt werden.In the case of a one-sided luminaire, that is to say only with a light exit on a front side, a mounting plate for quick installation can be used as an opaque wall element 1.2 on the rear side. When installing the luminaire, this mounting plate, on which, for example, the connection terminals, the illuminant and a ballast are located, can be installed and installed. The luminaire housing can then be snapped onto the mounting plate in the easiest way when it is opened.
