An den benachbart übereinander liegenden Rändern von Wanne (15) und Gehäuse (10) ist mindestens je ein nach innen vorspringender Vorsprung (20, 19) vorgesehen, die gleichsinnig und parallel zueinander angeordnet und ausgerichtet sind, so daß sie im montierten Zustand von Wanne und Gehäuse übereinander liegen. Mit dem Schieberelement (21, 30) ist für jedes Vorsprungspaar ein Maul (24, 25; 36, 37) gekuppelt, dessen Backen das Vorsprungspaar zwischen sich nehmen, sobald das Schieberelement aus der Löse- in die Verriegelungsstellung verschoben wird.A device for locking a light-transparent trough (15) of a linear luminaire with a housing (11) has a slide element (21) that can be operated manually, is displaceable and is longitudinally displaceable in the housing, with which connecting elements (24, 25) for connecting the trough ( 15) can be operated with the housing (10). At the adjacent superimposed edges of tub (15) and housing (10) at least one inwardly projecting projection (20, 19) is provided, which are arranged and aligned in the same direction and parallel to each other, so that they are in the assembled state of tub and Casings are on top of each other. With the slide element (21, 30) a jaw (24, 25; 36, 37) is coupled for each pair of projections, the jaws of which the pair of projections take between them as soon as the slide element is moved from the release position into the locking position.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbe­griff des Ansprüches 1.The invention relates to a device according to the preamble of claim 1.

Zwischen den Längskanten des Gehäuses und der Wanne, die im zusammengebauten Zustand zusammen mit Leuchtstofflam­pen und weiteren Einbauten eine Langfeldleuchte bilden, befindet sich zur Erzielung der erhöhten Sicherheit (s. VDE-Vorschriften) eine Dichtung; die beiden Ränder von Wanne und Gehäuse werden mittels einer von außen manuell zu betätigenden Verriegelungseinrichtung gegeneinander gedrückt.A seal is located between the longitudinal edges of the housing and the tub, which when assembled together with fluorescent lamps and other fittings form a linear luminaire to achieve increased safety (see VDE regulations); the two edges of the tub and the housing are pressed against one another by means of a locking device which can be operated manually from the outside.

Zu diesem Zweck befindet sich innerhalb des Gehäuses an dessen Boden ein in seiner Längsrichtung bzw. in der Längsrichtung der Langfeldleuchte verschiebbares Schie­berelement, an dem Haken angebracht sind, die hinter Zapfen an der Wanne greifen.For this purpose, there is a slide element in the longitudinal direction or in the longitudinal direction of the linear luminaire on the bottom of the housing on the base of which hooks are attached, which engage behind pins on the trough.

Aufgabe der Erfindung ist es, eine Vorrichtung der ein­gangs genannten Art weiter zu verbessern, insoweit, als die Dichtkraft immer auf einer bestimmten Größe gehalten werden kann.The object of the invention is to further improve a device of the type mentioned, insofar as the sealing force can always be kept at a certain size.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kenn­zeichnenden Merkmale des Anspruches 1.This object is achieved according to the invention by the characterizing features of claim 1.

Dabei sind zwei Möglichkeiten gegeben:There are two options:

Zum einen kann das Maul oder können die Mäuler an dem Schiebeelement angeformt sein; dies bedeutet, daß die Flächen der Backen, die aufeinanderzuweisen, mindestens in Schieberichtung derart geneigt sind, daß sich der Ab­stand zwischen diesen in Schieberichtung verändert; da­durch sind die beiden Backen an den sich gegenüberliegen­den Seiten keilförmig und schließen in Schieberichtung gesehen einen spitzen Winkel zwischen sich ein, wobei der Winkel in Verschieberichtung offen ist, so daß beim Über­schieben der beiden Backen über die Vorsprünge aufgrund der keilförmigen Abschrägung der Backen die Vorsprünge gegeneinander gedrückt werden, wodurch auch die Dicht­kraft erzeugt ist.On the one hand, the mouth or the mouths can be molded onto the sliding element; this means that the surfaces of the jaws which face one another are inclined at least in the sliding direction in such a way that the distance between them changes in the sliding direction; as a result, the two jaws are wedge-shaped on the opposite sides and, when viewed in the sliding direction, form an acute angle between them, the angle being open in the sliding direction, so that when the two jaws are pushed over the projections, the projections against one another due to the wedge-shaped beveling of the jaws be pressed, which also creates the sealing force.

Dabei besteht auch die Möglichkeit, daß die Backen quer zur Verschieberichtung geneigt sind, so daß das Maul in Maulöffnungsrichtung offen ist; dadurch wird eine wind­schiefartige Anordnung der beiden aufeinanderzuweisenden Flächen bewirkt und dadurch können auch Toleranzen quer zur Schieberichtung ausglichen werden.There is also the possibility that the jaws are inclined transversely to the direction of displacement, so that the mouth is open in the jaw opening direction; this results in a skewed arrangement of the two surfaces to be facing each other and thereby tolerances can also be compensated for transverse to the sliding direction.

Eine weitere Ausführungsform der Erfindung kann dahinge­hen, daß das Maul an einem Verriegelungselment angebracht ist, welches innerhalb des Gehäuses um eine in Richtung der Dichtungserstreckung verlaufende Achse drehbar ist; dazu ist dann am Schieberelement eine Steuerkulisse vor­gesehen, die den Schieber quer zur Schieberichtung über die beiden Vorsprünge drückt.A further embodiment of the invention can be that the mouth is attached to a locking element which is within the housing by one direction the axis of the seal extending is rotatable; for this purpose, a control link is then provided on the slide element, which presses the slide across the two projections transversely to the sliding direction.

Weiter vorteilhafte Ausgestaltungen und Verbesserungen sind den weiteren Unteransprüchen zu entnehmen.Further advantageous refinements and improvements can be found in the further subclaims.

Anhand der Zeichnung, in der einige Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung so­wie weitere vorteilhafte Ausgestaltungen und Verbesserun­gen näher erläutert und beschrieben werden.The invention and further advantageous refinements and improvements are to be explained and described in more detail with reference to the drawing, in which some exemplary embodiments of the invention are shown.

Eine Langfeldleuchte besitzt ein Gehäuse 10 mit einem Bodenteil 11 und zwei Seitenwänden, von denen lediglich die Seitenwand 12 dargestellt ist, an deren Randkante eine Dichtfläche 13 und ein senkrecht zum Bodenteil 11 verlaufender Randbord 14 vorgesehen ist. Die Langfeld­leuchte besitzt ferner eine lichttransparente Wanne 15, die an ihrem freien Rand eine umlaufende Rille 16 auf­weist, in der eine Dichtung 17 untergebracht ist, die im verschlossenen Zustand der Langfeldleuchte gegen die Dichtfläche 13 wirkt.A linear luminaire has a housing 10 with a bottom part 11 and two side walls, of which only the side wall 12 is shown, on the edge of which a sealing surface 13 and a rim 14 running perpendicular to the bottom part 11 is provided. The linear luminaire also has a light-transparent trough 15, which has a circumferential groove 16 on its free edge, in which a seal 17 is accommodated, which acts against the sealing surface 13 in the closed state of the linear luminaire.

An der Innenseite des freien Randes, beim Gehäuse 10 in Verlängerung der Dichtfläche und bei der Wanne 15 am in­neren Schenkel 18 schließen Vorsprünge 19 und 20 an, deren Anzahl der Anzahl von Verriegelungselementen (s. weiter unten) entspricht.On the inside of the free edge, in the housing 10 in the extension of the sealing surface and in the tub 15 on the inner leg 18, there are projections 19 and 20, the number of which corresponds to the number of locking elements (see below).

Am Bodenteil 11 und parallel dazu in Richtung der Längs­erstreckung der Langfeldleuchte, ist ein Schieberelement 21 verschiebbar geführt, an dessen Längskanten mehrere Verriegelungselmente 22 angeformt sind, die ein in der Ausführungsform nach Fig. 1 bis 3 jeweils einen unter einem Winkel zum Schieberelement 21 verlaufenden Steg 23 aufweisen, an dem maulförmig zwei Backen 24 und 25 ange­formt sind, wobei die beiden Schenkel bzw. Backen quer zur Längserstreckung des Schieberelementes 21 ein nach außen hin offenes U bilden. In ihrer Erstreckung in Längsrichtung, d.h. quer zum Schieberelement 21, sind die Innenflächen der Backen geneigt, so daß sich dort ein spitzer Winkel Alpha ergibt; darüberhinaus sind die Backen 24 auch in Verschieberichtung geneigt, so daß sich ein in Verschieberichtung offener Winkel Alpha₂ ergibt, s. Fig. 2 und Fig. 4. Die beiden Vorsprünge 19 und 20 können dann in gleicher Richtung und angenähert parallel auf ihren entgegesetzt liegenden Flächen geneigt sein, wie die Innenflächen der beiden Backen 24 und 25.On the bottom part 11 and parallel to it in the direction of the longitudinal extension of the linear luminaire, a slide element 21 is slidably guided, on the longitudinal edges of which a plurality of locking elements 22 are formed, each of which in the embodiment according to FIGS. 1 to 3 has a web running at an angle to the slide element 21 23, on which two jaws 24 and 25 are integrally formed, the two legs or jaws forming a U open to the outside transverse to the longitudinal extent of the slide element 21. In their extension in the longitudinal direction, ie transversely to the slide element 21, the inner surfaces of the jaws are inclined, so that there is an acute angle alpha; moreover, the jaws 24 are also inclined in the direction of displacement, so that there is an open angle Alpha₂ in the direction of displacement, see. Fig. 2 and Fig. 4. The two projections 19 and 20 can then in the same direction and approximately parallel be inclined on their opposing surfaces, like the inner surfaces of the two jaws 24 and 25.

Es besteht natürlich auch die Möglichkeit, einen Schieber 30 vorzusehen, in dem Nuten 31 eingebracht sind, in Wel­che ein Zapfen 32 eines Verriegelungselementes 33 ein­greift, welches Verriegelungselement 33 annähernd in sei­ner Mitte an einer Drehachse 34 am Gehäuse gelagert ist, wobei die Längserstreckung der Drehachse einerseits in die gleiche Richtung weist wie die Längserstreckung des Schiebers oder die Verschieberichtung oder die Längser­streckung der Dichtfläche.There is of course also the possibility of providing a slide 30, in which grooves 31 are made, into which a pin 32 of a locking element 33 engages, which locking element 33 is mounted approximately in the middle on an axis of rotation 34 on the housing, the longitudinal extent of the axis of rotation on the one hand points in the same direction as the longitudinal extension of the slide or the direction of displacement or the longitudinal extension of the sealing surface.

Die Nut 31 des Schieberelementes 30 ist gegenüber der Längskante 35 unter einem Winkel Beta ausgerichtet, so daß dann, wenn der Schieber oder das Schieberelement 30 sich in Pfeilrichtung P bewegt, der Zapfen 32 quer zur Pfeilrichtung P, also quer zur Verschieberichtung nach außen oder nach innen verschwenkt wird, so daß demgemäß die am Verriegelungselement angeformten Backen 36 und 37, die den Backen 24 und 25 entsprechen, über die Vorsprünge 19 und 20 oder von diesen beiden Vorsprüngen weg bewegt werden. Zu diesem Zweck wäre die Innenfläche der beiden Backen 36 und 37 in Verschwenkrichtung geneigt und geöff­net, s. Winkel Alpha zwischen den beiden Backen 24 und 25 der Fig. 3.The groove 31 of the slider element 30 is aligned with respect to the longitudinal edge 35 at an angle beta, so that when the slider or the slider element 30 moves in the direction of the arrow P, the pin 32 transversely to the direction of the arrow P, that is to say transversely to the direction of displacement to the outside or towards is pivoted inside, so that the molded on the locking element jaws 36 and 37, which correspond to the jaws 24 and 25, are moved over the projections 19 and 20 or away from these two projections. For this purpose, the inner surface of the two jaws 36 and 37 would be inclined and opened in the pivoting direction, see FIG. Angle alpha between the two jaws 24 and 25 of FIG. 3.
