Abstract

An elongated light fixture has a housing (11) and a transparent cover trough (18) attached thereto, a seal (20) and a device being inserted therebetween. Provided for the purpose of detachably connecting the trough (18) to the housing (11) is a device having an externally actuatable transmission for driving at least one actuating element which extends in the housing and with which at least one locking element (23) for fixing the trough (18) to the housing (11) cooperates. In order to achieve stress-free retention of the trough (18) on the housing (11), the locking elements (23) in the housing (11) are provided as rotatably mounted hooks which, driven by the actuating elements (28), are pressed in the locking state with their free hook-shaped end (25) against one projection each on the trough (18), and thus press the free edge of the trough (18) against the housing (11). Arranged in addition on each hook (57) is a spring (69) which loads the hook in its pressing-in direction against the projection on the trough (18), there being provided on the actuating elements (28) means which upon opening press the hooks away from the projection against the force of the spring, and release the springs upon closure. <IMAGE>

Description

Die Erfindung betrifft eine Langfeldleuchte nach dem Oberbegriff des Anspruches 1.The invention relates to a linear luminaire according to the preamble of claim 1.

Langfeldleuchten der eingangs genannten Art, die den Vorschriften für Explosionsschutz oder Schlagwetterschutz genügen, benötigen ein Gehäuse mit einer Abdeckwanne, welche dicht miteinander verbindbar sind, damit der Raum innerhalb der Leuchte eine den Vorschriften entsprechende erhöhte Sicherheit aufweist.Long-range luminaires of the type mentioned at the outset which meet the regulations for explosion protection or firedamp protection require a housing with a cover trough which can be connected tightly to one another so that the space inside the luminaire has an increased level of security which corresponds to the regulations.

Bei bekannten Langfeldleuchten befinden sich an einer der Längsseiten Scharniere, mit denen die Wanne am Gehäuse abschwenkbar verbunden ist; an der anderen Längskante sind mit Haken versehene, die Leuchte durchgreifende, mit dem Gehäuse verbundene Schieber vorgesehen. An der Wanne sind Zapfen angeordnet und wenn die längsverlaufenden Schieber in ihrer Längsrichtung verschoben werden, dann hintergreifen die Haken die Zapfen an der Wanne, so daß eine dichte Verbindung zwischen der Wanne und dem Gehäuse erzielt wird. Die Scharniere, die außerhalb des Gehäuses bzw. der Wanne angeordnet sind, lassen dabei zumindest auf dieser Seite wegen ihrer Geometrie nur eine bestimmte unveränderliche Dichtkraft zwischen der Wanne und dem Gehäuse zu und eine Nachstellbarkeit ist hier nicht möglich. Wenn die Dichtung zwischen Wanne und Gehäuse altert, besteht die Gefahr, daß dort Undichtigkeiten entstehen. Darüberhinaus besteht das Problem, daß insbesondere im Bereich der Scharniere bei längerdauernder Krafteinwirkung im verschlossenen Zustand ein Kaltfluß des Wannen- oder/und Gehäusematerials ebenfalls mit Verschlechterung der Dichtungswirkung eintritt. Weiterhin ist zu befürchten, daß an der Wanne insbesondere im Bereich der Scharniere durch Verbiegung der Wanne im Krafteinleitungsbereich eine Spannungsrißkorrosion auftreten kann, die schlußendlich zur Zerstörung der Wanne führt.Known linear luminaires have hinges on one of the long sides with which the trough is pivotally connected to the housing; on the other longitudinal edge, hooks are provided, which penetrate the lamp and are connected to the housing. Pins are arranged on the tub and when the longitudinal slides are moved in their longitudinal direction, the hooks engage behind the pins on the tub, so that a tight connection between the tub and the housing is achieved. The hinges, which are arranged outside the housing or the trough, only allow a certain, unchangeable sealing force between the trough and the housing, at least on this side, because of their geometry, and adjustment is not possible here. If the seal between the tub and the housing ages, there is a risk that leaks will occur there. In addition, there is the problem that, particularly in the area of the hinges, when the force is applied for a long time in the closed state, a cold flow of the tub or / and housing material also occurs with a deterioration in the sealing effect. It is also to be feared that stress cracking corrosion can occur on the tub, in particular in the area of the hinges, due to bending of the tub in the area of force introduction, which ultimately leads to the tub being destroyed.

Eine Langfeldleuchte der eingangs genannten Art ist aus der DE-B 10 19 009 bekannt geworden. Die Haken, die zum Andrücken der Wanne an das Gehäuse dienen, werden durch je eine schräg verlaufende Kulisse gesteuert; da der Bereich der Kulissen, in dem sich die Haken in Verriegelungsstellung befinden, genau in Verschieberichtung der Betätigungselemente verläuft, ist eine Nachstellung der Andrückkraft nicht möglich, so daß im Laufe der Zeit mit einer Verschlechterung der Dichtwirkung gerechnet werden muß. Im übrigen müssen die Haken zur Erreichung der Dichtwirkung um eine Achse verschwenkt werden, die senkrecht zur Bewegungsrichtung der Betätigungselemente verläuft.A linear light of the type mentioned is known from DE-B 10 19 009. The hooks, which are used to press the tub onto the housing, are each controlled by an inclined backdrop; since the area of the scenes, in which the hooks are in the locking position, runs exactly in the direction of displacement of the actuating elements, an adjustment of the pressing force is not possible, so that a deterioration in the sealing effect must be expected over time. In addition, the hooks must be pivoted to achieve the sealing effect about an axis that is perpendicular to the direction of movement of the actuating elements.

Gleichzeitig mit dem Verriegelungs- und Entriegelungsvorgang wird ein im Inneren der Leuchte befindlicher Schalter betätigt, der die Lampenversorgung zuschaltet, wenn die Verriegelung vorgenommen wird, und sie abschaltet, wenn entriegelt wird.Simultaneously with the locking and unlocking process, a switch located inside the lamp is actuated, which switches on the lamp supply when the locking is carried out and switches it off when the unlocking takes place.

Aufgabe der Erfindung ist es, eine Langfeldleuchte der eingangs genannten Art zu schaffen, bei der die Verbindung zwischen Wanne und Gehäuse auch nach längerer Gebrauchsdauer abgedichtet bleibt.The object of the invention is to provide a linear luminaire of the type mentioned, in which the connection between the tub and the housing remains sealed even after a long period of use.

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

Dadurch, daß die Drehachsen der Verriegelungselemente, also der Haken, erfindungsgemäß parallel zur Erstreckungsrichtung der Dichtungsflächen zwischen dem Gehäuse und der Wanne verlaufen, können die Andrückkräfte der Haken nachträglich nachgestellt werden.Due to the fact that the axes of rotation of the locking elements, ie the hooks, according to the invention run parallel to the direction of extent of the sealing surfaces between the housing and the trough, the pressing forces of the hooks can be adjusted subsequently.

Eine weitere vorteilhafte Ausgestaltung der Erfindung kann dahin gehen, daß am Haken eine Feder angeordnet ist, die den Haken in Richtung Zudrücken des Hakens gegen den Vorsprung beaufschlagt, und daß an den Schieberelementen Mittel vorgesehen sind, die beim Öffnen die Haken entgegen der Kraft der Federn von dem Vorsprung wegdrücken und beim Schließen die Federn freigeben, so daß über die Vorsprünge die freien Kanten der Wanne gegen das Gehäuse gedrückt sind.A further advantageous embodiment of the invention can be that a spring is arranged on the hook, which acts on the hook in the direction of pressing the hook against the projection, and that means are provided on the slide elements, which open the hooks against the force of the springs when opening Push away from the projection and release the springs when closing, so that the free edges of the tub are pressed against the housing via the projections.

Durch das Vorsehen der Federn an jedem Haken wird auch dann eine Dichtung zwischen der Wanne und dem Gehäuse bewirkt, wenn die Dichtelemente, die zwischen der Wanne und dem Gehäuse eingesetzt sind, aufgrund einer Alterung verspröden oder sich plastisch verformen und damit eine Öffnung ins Innere der Wanne freigeben würden. Im Endeffekt ist hierdurch eine Selbstnachspannung bewirkt, mit der auch Toleranzen ausgeglichen werden können.The provision of the springs on each hook causes a seal between the trough and the housing even if the sealing elements, which are inserted between the trough and the housing, become brittle or plastically deform due to aging and thus open into the interior of the Would release the tub. The end result is self-tensioning, with which tolerances can also be compensated.

Eine besonders vorteilhafte Betätigung der Haken erfolgt über Schieberelemente, wie sie an sich schon bekannt sind. Zur Steuerung der Haken ist in vorteilhafter Weise das den Schieberelementen zugewandte Ende jedes Hakens mit an den Schieberelementen angeordneten, der Anzahl der Haken entsprechende Anzahl von Steuerkulissen gekuppelt, so daß beim Verschieben der Schieberelemente jeder Haken in Verriegelungsstellung oder in Freigebestellung verschwenkt wird.A particularly advantageous actuation of the hook takes place via slide elements, as are known per se. In order to control the hooks, the end of each hook facing the slide elements is coupled with the number of control links arranged on the slide elements and corresponding to the number of hooks, so that when the slide elements are moved, each hook is pivoted into the locking position or in the released position.

Dabei verläuft in vorteilhafter Weise die Steuerkulisse etwa parallel zu der Achse und besitzt auch zwei Bereiche, die eine unterschiedliche Entfernung von der Drehachse einnehmen, und einen beide Bereiche verbindenden Zwischenbereich, die das mit ihr gekuppelte Ende des Hakens führen.The control link advantageously runs approximately parallel to the axis and also has two regions which take up a different distance from the axis of rotation, and an intermediate region connecting both regions, which guide the end of the hook coupled to it.

Damit die Federn freigegeben werden können, ist die Steuerkulisse als eine Nut ausgebildet, deren Seitenflächen einen am Ende des Hakens befindlichen Zapfen zwischen sich aufnehmen und führen, und der Nutgrund der Steuerkulisse besitzt in besonders vorteilhafter Weise unterschiedliche Abstände von der Drehachse der Haken, wobei der Nutgrund des Bereiches der Nut, der die Lösestellung des Hakens bewirkt, näher an der Drehachse des Hakens angeordnet ist. Damit der Haken federnd gegen den Nutgrund gedrückt werden kann, um die Nachspannung bewirken zu können, ist er in seine Längsrichtung verschieblich gelagert.So that the springs can be released, the control link is designed as a groove, the side surfaces of which receive and guide a pin located at the end of the hook between them, and the groove base of the control link has, in a particularly advantageous manner, different distances from the axis of rotation of the hooks, the Groove bottom of the area of the groove that causes the release position of the hook is arranged closer to the axis of rotation of the hook. So that the hook can be pressed resiliently against the groove base in order to be able to effect the re-tensioning, it is slidably mounted in its longitudinal direction.

Speziell durch diese Maßnahme wird eine Nachspannung in besonders vorteilhafter Weise erleichtert.This measure, in particular, facilitates re-tensioning in a particularly advantageous manner.

Die Verriegelungselemente, die durch einzelne Haken gebildet sind, können auch durch eine durchgehende Schiene gebildet werden, die in ihrem Querschnitt der Form jedes Verriegelungselementes bzw. jedes Hakens entspricht; dabei ist dann an der den Schieberelementen zugewandten Kante der Schiene, welche Schiene ja in Längsrichtung der Langfeldleuchte sich erstreckt, mindestens ein Zapfen angeordnet, der in eine entsprechende Nut eingreift; die Anzahl der Zapfen wird dabei von der Festigkeit des Materials, aus dem das Verriegelungselement besteht, bestimmt; möglicherweise können vier oder fünf Zapfen oder Füße, die in die entsprechenden Nuten eingreifen, ausreichen.The locking elements, which are formed by individual hooks, can also be formed by a continuous rail which corresponds in cross section to the shape of each locking element or hook; then at least one pin is arranged on the edge of the rail facing the slide elements, which rail extends in the longitudinal direction of the linear luminaire, and engages in a corresponding groove; the number of pins is determined by the strength of the material from which the locking element is made; four or five pins or feet which engage in the corresponding grooves may be sufficient.

Wenn mehrere Verschlußelemente, also mehrere einzelne Haken vorgesehen sind, dann hat dies den Vorteil, daß bei Ausfall eines der Verschlußverriegelungselemente die Dichtwirkung der übrigen praktisch nicht beeinträchtigt wird.If a plurality of closure elements, that is to say a plurality of individual hooks, are provided, this has the advantage that the sealing effect of the others is practically not impaired if one of the closure locking elements fails.

Weitere Ausgestaltungen und Verbesserungen der Erfindung sind den weiteren Unteransprüchen zu entnehmen.Further refinements and improvements of the invention can be found in the further subclaims.

Die Fig. 1 zeigt eine Langfeldleuchte 10, die ein wannenförmiges Gehäuse 11 aufweist, an dessen Bodenteil 12 schräg und einen offenen stumpfen Winkel miteinander bildende Seitenwände 13 und 14 angeformt sind, die über nicht bezeichnete Stirnwände verbunden sind, wodurch sich eine Wannenform für das Gehäuse ergibt. Die Enden der Seitenwände besitzen einen an der Wannenform umlaufenden Rand 15 mit einer parallel zum Bodenteil 12 verlaufenden Dichtfläche 16 und einer senkrecht dazu verlaufenden Randfläche 17. Mit dem Gehäuse 11 ist eine Wanne 18 aus klartransparentem, elektrisch isolierendem Material verbunden, die im Querschnitt eine U-Form aufweist, an deren freien Randkanten eine in die gleiche Richtung wie die U-Form der Wanne 18 offene, ebenfalls U-förmige Rinne 19 angeformt ist, die eine mit der Dichtfläche 16 zusammenwirkende umlaufende Dichtung 20 aufnimmt. In der Wanne 18 angedeutet sind zwei nebeneinander liegende, parallel verlaufende Leuchtstofflampen 21 und 22 aufgenommen (siehe hierzu auch Fig. 4), die am Gehäuse 11 gehalten sind und mittels im Gehäuse 11 befestigter elektrischer Komponenten mit Strom versorgt werden.Fig. 1 shows a linear luminaire 10, which has a trough-shaped housing 11, on the bottom part 12 are formed obliquely and an open obtuse side walls 13 and 14 are formed, which are connected via end walls, not designated, whereby a trough shape for the housing results. The ends of the side walls have a peripheral edge 15 on the trough shape with a sealing surface 16 running parallel to the base part 12 and an edge surface 17 running perpendicular thereto. A trough 18 made of clearly transparent, electrically insulating material is connected to the housing 11 and has a U-shaped cross section -Shaped, on the free edge of which a U-shaped channel 19, which is open in the same direction as the U-shape of the tub 18, is formed, which receives a circumferential seal 20 cooperating with the sealing surface 16. Indicated in the tub 18 are two juxtaposed, parallel fluorescent lamps 21 and 22 (see also FIG. 4) which are held on the housing 11 and are supplied with power by means of electrical components fastened in the housing 11.

Zur Verbindung der Wanne 18 mit dem Gehäuse 11 sind mehrere hakenförmige Verriegelungselemente 23 vorgesehen, die mittels eines Zapfens 24 am Gehäuse 11 drehbar gelagert sind, wobei die Längsachse des Zapfens 24 parallel zur Längserstreckung der Dichtung 20 bzw. der Dichtfläche 16 verläuft. Das hakenförmige Verriegelungselement 23 besitzt (wie jedes Verbindungselement) an seinem einen Ende eine Verriegelungsnase 25, die mit der Wanne zusammenwirkt, und an seinem anderen Ende eine Abkröpfung 26 mit einem Zapfen 27, der im Verriegelungszustand angenähert senkrecht zum Bodenteil 12 verläuft.To connect the tub 18 to the housing 11, a plurality of hook-shaped locking elements 23 are provided which are rotatably mounted on the housing 11 by means of a pin 24, the longitudinal axis of the pin 24 running parallel to the longitudinal extent of the seal 20 or the sealing surface 16. The hook-shaped locking element 23 (like each connecting element) has at one end a locking lug 25, which cooperates with the trough, and at its other end an offset 26 with a pin 27, which in the locked state extends approximately perpendicular to the base part 12.

Am Bodenteil 12 ist ein Schieberelement 28 verschieblich gelagert, wobei am Bodenteil 12 mehrere kreisförmige Führungsvorsprünge 29 angeformt sind, die je ein Langloch 30 im Schieberelement 28 durchgreifen, die eine Verschiebung in Längsrichtung der Leuchte 10 gestatten. Die Anzahl dieser Führungen ist zumindest zwei, damit nur eine Längsverschiebung, nicht aber eine Verdrehung des Schieberelementes 28 gewährleistet ist.A slider element 28 is displaceably mounted on the bottom part 12, a plurality of circular guide projections 29 being formed on the bottom part 12, each of which extends through an elongated hole 30 in the slider element 28, which permit displacement in the longitudinal direction of the lamp 10. The number of these guides is at least two, so that only a longitudinal displacement but not a rotation of the slide element 28 is ensured.

In dem Schieberelement 28 befindet sich eine der Anzahl der Verriegelungselemente 23 entsprechende Anzahl Nuten 31, die im wesentlichen in einem Winkel Alpha zur Längsachse bzw. zur Längserstreckung des Schieberelementes 28 ausgerichtet sind, in welche Nuten die Zapfen 27 an den Verriegelungselementen 28 eingreifen. Die Nuten 31 können auch als die Schieberelemente durchgreifende Durchbrüche ausgebildet sein, wie in Fig. 1 dargestellt.In the slide element 28 there is a number of grooves 31 corresponding to the number of locking elements 23, which are oriented essentially at an angle alpha to the longitudinal axis or to the longitudinal extension of the slide element 28, into which grooves the pins 27 on the locking elements 28 engage. The grooves 31 can also be designed as openings penetrating the slide elements, as shown in FIG. 1.

Wie aus der Fig. 2 ersichtlich, sind die Nuten 31 so den hakenförmigen Verriegelungselementen 23 zugeordnet, daß in der Verriegelungsstellung je der Zapfen 27 einen größeren Abstand D₁ von der benachbarten Längskante 32 des Schieberelementes 28 einnimmt als in der anderen Stellung, bei der der Abstand D₂ ist. Jene Stellung wird erreicht, wie aus Fig. 2 ersichtlich ist, durch Verschieben des Schieberelementes 28 aus der Stellung 28₁ in die Stellung 28₂ des Schieberelementes 28; die Indizes sollen nicht zur Unterscheidung der beiden Schieberelemente dienen, sondern lediglich andeuten, daß hier zwei unterschiedliche Stellungen eingenommen worden sind. Links von der Mittellinie ist die Wanne 18 mit dem Gehäuse 12 fest verbunden, wogegen rechts, wenn also der Zapfen 27 den kleineren Abstand von der Längskante 32 einnimmt, die Lösestellung angedeutet ist, in der die Wanne 18 von dem Gehäuse 12 und von den Verriegelungsnasen 25 gerade freikommen kann.As can be seen from Fig. 2, the grooves 31 are assigned to the hook-shaped locking elements 23 that in the locking position each of the pins 27 a larger distance D₁ from the adjacent longitudinal edge 32 of Slider element 28 occupies than in the other position, in which the distance is D₂. That position is reached, as can be seen from FIG. 2, by moving the slide element 28 from the position 28 1 to the position 28 2 of the slide element 28; the indices are not intended to differentiate between the two slide elements, but merely to indicate that two different positions have been adopted here. To the left of the center line, the tub 18 is firmly connected to the housing 12, whereas on the right, if the pin 27 is at a smaller distance from the longitudinal edge 32, the release position is indicated, in which the tub 18 is removed from the housing 12 and from the locking lugs 25 can just be released.

Die Verriegelungsnasen 25 der Verriegelungselemente 23 drücken auf die Bodenfläche der U-förmigen Rinne 19 der Wanne 18. Dadurch wird die Krafteinleitung der Druckkraft der Verriegelungsnasen 25 auf die Wanne besser über die gesamte Länge der Rinne verteilt, und es ist festzustellen, daß durch diese Einleitung der Kraft in die Wanne Verbiegungen der Wannenschale im wesentlichen vermieden sind. Dadurch vermeidet man auch Spannungsrißkorrosionen insbesondere durch Dehnungen auf den Außenflächen der Wanne. Man kann festhalten, daß die Krafteinleitung um so besser ist, je näher die Verriegelungsnase 25 an der Innenfläche der Wanne liegt.The locking lugs 25 of the locking elements 23 press on the bottom surface of the U-shaped channel 19 of the trough 18. As a result, the introduction of force by the pressure force of the locking lugs 25 onto the trough is better distributed over the entire length of the channel, and it can be seen that this introduction The force in the tub bends in the tub shell are substantially avoided. This also prevents stress corrosion cracking, in particular due to stretching on the outer surfaces of the tub. It can be said that the closer the locking lug 25 is to the inner surface of the tub, the better the introduction of force.

Die Verriegelungselemente 23 bzw. die Zapfen 24 sind an einem podestartigen Vorsprung 33 an der Innenfläche der Seitenwände 13 und 14 gelagert.The locking elements 23 and the pins 24 are mounted on a platform-like projection 33 on the inner surface of the side walls 13 and 14.

Auf dem in Fig. 1 und 2 beschriebenen Verriegelungsprinzip basieren alle im folgenden näher erläuterte weitere Ausführungsformen der Erfindung.All further embodiments of the invention which are explained in more detail below are based on the locking principle described in FIGS. 1 and 2.

Es sei nun Bezug genommen auf die Fig. 4.Reference is now made to FIG. 4.

Die dort gezeigte Langfeldleuchte 40 besitzt ein Gehäuse 41, das im Grundaufbau dem Gehäuse 11 der Fig. 1 entspricht und ein Bodenteil 42 sowie Seitenwände 43 und 44 mit einem daran anschließenden Rand 45 aufweist. Mit diesem Gehäuse 41 ist die Wanne 18 verbunden. Innerhalb der Wanne 18 befinden sich die beiden Leuchtstofflampen 21 und 22, denen Reflektoren 51 und 52 zugeordnet sind.The linear light 40 shown there has a housing 41 which corresponds in its basic structure to the housing 11 in FIG. 1 and has a base part 42 and side walls 43 and 44 with an adjoining edge 45. The tub 18 is connected to this housing 41. The two fluorescent lamps 21 and 22, to which reflectors 51 and 52 are assigned, are located inside the tub 18.

Am Bodenteil 42 springt ein dem Vorsprung 29 entsprechender zylinderförmiger Vorsprung 49/46 vor, der einen kragenartigen Fortsatz 47 aufweist, der zur Führung eines Schieberelementes 48 dient. An den Längskanten des Schieberelementes 48 sind senkrecht zu der durch das Schieberelement 48 gebildeten Ebene in Richtung zur Wanne 18 Vorsprünge 49 angeformt, die auf ihrer Außenfläche - bezogen auf das Schieberelement 48 - je eine Kulissenfläche 50 aufweisen bzw. bilden, dergestalt, daß der Abstand der Kulissenfläche 50 sich von der Mittelachse M-M des Schieberelementes 48 in Richtung der Längskanten verändert; an der Längskante 54 sind zur Bildung der Kulissenflächen Rücksprünge 55 vorgesehen, deren innerer, also der Mittellinie nächstgelegener Abschnitt 53 über eine Schrägfläche 56 zur Längskante 54 übergeht.A cylindrical projection 49/46, corresponding to the projection 29, projects on the base part 42 and has a collar-like extension 47, which is used to guide a slide element 48. On the longitudinal edges of the slide element 48, projections 49 are formed perpendicular to the plane formed by the slide element 48 in the direction of the trough 18, each of which has or form a link surface 50 on its outer surface, based on the slide element 48, such that the distance the link surface 50 changes from the central axis MM of the slide element 48 in the direction of the longitudinal edges; Recesses 55 are provided on the longitudinal edge 54 to form the link surfaces, the inner portion 53 thereof, ie the portion closest to the center line, merges with the longitudinal edge 54 via an inclined surface 56.

Als Verriegelungselemente sind den Verriegelungselementen 23 entsprechende Verriegelungselemente 57 vorgesehen. Diese Verriegelungselemente 57 besitzen an einem ihrer Enden eine Verriegelungsnase 58 und am entgegengesetzen Ende eine angenähert parallel zum Schieberelement bzw. zur Bodenplatte 42 verlaufende Steuernase 59, wobei die Längserstreckung des Verriegelungselementes ähnlich wie die des Verriegelungselmentes 23 angenähert parallel zu der benachbarten Seitenwand 13 bzw. 14 oder 43/44 verläuft. Im mittleren Bereich zwischen der Verriegelungsnase und der Steuernase besitzt das Verriegelungselement einen annähernd trapezförmigen oder dreieckförmigen Körper, der eine der Seitenwand benachbarte Basisebene 61 und zwei ein Dreieck damit bildende Oberkanten 62 und 63, die eine Ecke 64 miteinander bilden, wogegen die Basisebene 61 mit der Verriegelungsnase 51 eine zweite Ecke 65 bildet, welche Ecke 65 auf der Innenfläche der Seitenwand 40 bzw. auf den Innenwänden der Seitenwände 43 und 44 sich drehen kann.Corresponding locking elements 57 are provided as locking elements 23. These locking elements 57 have a locking lug 58 at one end and a control lug 59 running approximately parallel to the slide element or to the bottom plate 42 at the opposite end, the longitudinal extension of the locking element similar to that of the locking element 23 being approximately parallel the adjacent side wall 13 or 14 or 43/44. In the middle region between the locking lug and the control lug, the locking element has an approximately trapezoidal or triangular body, which has a base plane 61 adjacent to the side wall and two upper edges 62 and 63 forming a triangle therewith, which form a corner 64 with one another, whereas the base plane 61 with the Locking lug 51 forms a second corner 65, which corner 65 can rotate on the inner surface of the side wall 40 or on the inner walls of the side walls 43 and 44.

Senkrecht an dem Bodenteil 42 des Gehäuses 41 sind an den Übergängen zwischen dem Bodenteil 42 und den Seitenwänden 43 und 44 je eine senkrecht dazu verlaufende Führungswand 66 angeformt, die Durchbrüche 67 besitzt, durch die die Steuernasen 59 der Verriegelungselemente 58 hindurchgreifen. Der Körper 60 des Verriegelungselementes besitzt, ausgehend von der Basiskante 61, eine Vertiefung 68, in der eine Druckfeder 69 eingesetzt ist. Durch die Druckfeder, in Verbindung mit der Steuernase 59, wird das Verriegelungselement bzw. werden die Verriegelungselemente an Ort und Stelle gehalten.Perpendicularly to the bottom part 42 of the housing 41, a perpendicular guide wall 66 is formed on the transitions between the bottom part 42 and the side walls 43 and 44, which has openings 67 through which the control lugs 59 of the locking elements 58 extend. The body 60 of the locking element has, starting from the base edge 61, a recess 68 in which a compression spring 69 is inserted. The locking element or the locking elements are held in place by the compression spring in connection with the control lug 59.

Die Steuernase 59 wirkt mit dem Rücksprung 55 so zusammen, daß beim Verschieben in die Doppelpfeilrichtung P die Steuernase 59 einmal in den Rücksprung 55 hineingreift und zum anderen auf der Außenfläche bzw. Außenseite der Längskante 54 aufliegt. Wenn sich die Steuernase 59 innerhalb des Rücksprunges 55 befindet, dann ist dies die dick ausgezogene Verriegelungsstellung, in der die Wanne 18 mit der Rinne 19 gegen die Dichtfläche am Rand 45 gedrückt wird, welche Dichtfläche der Dichtfläche 16 entspricht. Wenn sich die Steuernasen 59 auf der Außenfläche oder der Außenseite der Längskante 54 befinden, dann nehmen diese die strichlierte Lage (s. Fig. 4) ein, die die Lösestellung ist.The control lug 59 interacts with the recess 55 in such a way that the control lug 59 engages once in the recess 55 when it is moved in the double arrow direction P and, on the other hand, rests on the outer surface or outside of the longitudinal edge 54. If the control lug 59 is within the recess 55, then this is the thick extended locking position in which the trough 18 with the groove 19 is pressed against the sealing surface at the edge 45, which sealing surface corresponds to the sealing surface 16. If the control lugs 59 on the Outer surface or the outside of the longitudinal edge 54, then they take the dashed position (see Fig. 4), which is the release position.

Zur Verbindung der Wanne mit dem Gehäuse ist an der Wanne ein Filmscharnier 70 angeformt, welches mit dem Gehäuse 41 im Bereich der Seitenwand 43 mittels einer Schraubenverbindung 71 befestigt ist. Selbstverständlich sind mehrere derartiger Filmscharniere 70 auf der in der Fig. 4 dargestellten rechten Seite vorhanden.To connect the tub to the housing, a film hinge 70 is formed on the tub, which is fastened to the housing 41 in the region of the side wall 43 by means of a screw connection 71. Of course, there are several such film hinges 70 on the right-hand side shown in FIG. 4.

Die Verschiebung des Schieberelementes 48 in Pfeilrichtung P erfolgt mittels eines Zahnradgetriebes. Zu diesem Zweck besitzt die Seitenwand 43 in der Mitte der Langfeldleuchte 40 einen Einzug 72, der einen Wandabschnitt 73 aufweist, der senkrecht zum Bodenteil 42 verläuft. Durch eine Bohrung 74 in diesem Wandabschnitt ist ein Antriebszapfen 75 abgedichtet hindurchgeführt.The slide element 48 is displaced in the direction of arrow P by means of a gear mechanism. For this purpose, the side wall 43 has a draw-in 72 in the middle of the linear luminaire 40, which has a wall section 73 which runs perpendicular to the base part 42. A drive pin 75 is passed through a bore 74 in this wall section in a sealed manner.

Der Antriebszapfen besitzt an seinem einen Ende eine Vierkantprofilierung 76, an der ein radialer Bund 77 anschließt, mit dem der Antriebszapfen 75 gegen die Außenfläche der Wandung 73 zum Anliegen kommt. Das andere, innerhalb des Gehäuses 41 befindliche Ende des Antriebszapfens besitzt ein Zahngetriebeelement 77, welches mit einer zahnstangenartigen Ausgestaltung 78 am Schieberelement 48 zusammenwirkt, wie weiter unten näher anhand eines anderen Ausführungsbeispiels der Langfeldleuchte beschrieben werden soll. Die Wirkungsweise ist so, daß bei Verdrehen des Antriebszapfens 75 mittels eines auf das Vierkantprofil 76 auf steckbaren Werkzeuges über das Zahngetriebeelement 77 und die zahnstangenartige Ausgestaltung 78 das Schieberelement 48 in Pfeilrichtung P hin und her verschoben werden kann. Die Führung des Schieberelementes 48 erfolgt dadurch, daß in dem Schieberelement Langlöcher 79 vorgesehen sind, durch die ein in den Vorsprung 46/47 eingeschraubter Schraubenbolzen 80 mit einer Führungsscheibe 81 das Langloch 79 durchgreift und so zu einer Führung dient, wie oben beschrieben.The drive pin has at one end a square profile 76, to which a radial collar 77 connects, with which the drive pin 75 comes to rest against the outer surface of the wall 73. The other end of the drive pin located within the housing 41 has a toothed gear element 77 which interacts with a rack-like configuration 78 on the slide element 48, as will be described in more detail below with the aid of another exemplary embodiment of the linear light. The mode of operation is such that when the drive pin 75 is rotated by means of a tool which can be plugged onto the square profile 76 by means of the toothed gear element 77 and the rack-like configuration 78, the slide element 48 can be moved back and forth in the direction of the arrow P. The slide element 48 is guided in that in the slide element Elongated holes 79 are provided, through which a screw bolt 80 screwed into the projection 46/47 with a guide disk 81 passes through the elongated hole 79 and thus serves as a guide, as described above.

Die Fig. 6 zeigt eine Langfeldleuchte 82, die das Gehäuse 11 und die Wanne 18 umfaßt; innerhalb des Gehäuses 11 ist parallel zu diesem ein Schieberelement 83 angeordnet, welches mehrere Nuten 84 (s. weiter unten) aufweist, in welche ein Fuß 85 je eines Verriegelungselementes 86 eingreift. Das Verriegelungselement 86 besitzt einen mit parallel verlaufenden Längsseiten seitlich begrenzten Körper 87, an dessen einem Ende eine Verjüngung 89 mit einer Verriegelungsnase 90 angeformt ist, wogegen am anderen Ende ein L-förmiger Fuß 91, der dem Fuß 84 etwa entspricht, angeformt und angebracht ist. Der L-förmige Fuß besitzt einen L-förmigen freien Schenkel 92, der etwa in die entgegengesetzte Richtung wie die Verriegelungsnase 90 am Fuß 91 angeformt ist. Innerhalb des Körpers 87 ist eine längliche Ausnehmung 88 eingebracht, die an ihrem verriegelungsnasenseitigen Ende eine Abrundung 93 und an ihrem fußseitigen Ende eine Auflagefläche 94 mit einem daran angreifenden Führungszapfen 95 aufweist; innerhalb der Ausnehmung 88 ist eine Druckfeder 96 aufgenommen, die durch den Führungszapfen 95 geführt ist. An den Seitenwänden 13 und 14 des Gehäuses 10 sind Vorsprünge 33 (s. Fig. 1) vorgesehen, die den Zapfen 24 tragen, der die Ausnehmung 88 durchgreift (s. Fig. 4, strichliert gezeigt). Die Druckfeder 96 stützt sich einerseits gegen die Auflagefläche 94 und andererseits gegen die Achse bzw. den Zapfen 24 ab.Fig. 6 shows a linear light 82, which includes the housing 11 and the tub 18; Within the housing 11, a slide element 83 is arranged parallel to the latter, which has a plurality of grooves 84 (see below), into which a foot 85 engages one locking element 86 each. The locking element 86 has a body 87 which is laterally delimited with parallel longitudinal sides, at one end of which a taper 89 is formed with a locking lug 90, whereas at the other end an L-shaped foot 91, which corresponds approximately to the foot 84, is formed and attached . The L-shaped foot has an L-shaped free leg 92, which is formed approximately in the opposite direction to the locking lug 90 on the foot 91. An elongated recess 88 is made inside the body 87, which has a rounded portion 93 on its locking nose-side end and a support surface 94 with a guide pin 95 engaging thereon on its foot-side end; a compression spring 96 is received within the recess 88 and is guided through the guide pin 95. On the side walls 13 and 14 of the housing 10, projections 33 (see FIG. 1) are provided which carry the pin 24 which extends through the recess 88 (see FIG. 4, shown in broken lines). The compression spring 96 is supported on the one hand against the bearing surface 94 and on the other hand against the axis or the pin 24.

Die Fig. 11 zeigt eine Aufsicht auf das Schieberelement 83 mit der Nut 84, welche, wie aus der Fig. 6 ersichtlich, im Querschnitt eine L-Form aufweist, die bezogen auf die Mittelachse des Schieberelementes 83 so geformt ist, daß sie einen L-förmigen Bereich 84₁, der näher der Mittelachse ist, und einen L-förmigen Bereich 84₂, der von der Mittelachse des Schieberelementes 83 weiter entfernt ist, besitzt.FIG. 11 shows a plan view of the slide element 83 with the groove 84, which, as can be seen from FIG. 6, has an L-shape in cross section, which is related on the central axis of the slide element 83 is shaped so that it has an L-shaped area 84 1, which is closer to the central axis, and an L-shaped area 84 2, which is further away from the central axis of the slide element 83.

Die Fig. 8, 9 und 10 zeigen ein speziell ausgebildetes Schieberelement, dessen Form auf der Form des Schieberelementes 83 basiert.8, 9 and 10 show a specially designed slide element, the shape of which is based on the shape of the slide element 83.

Das Schieberelement 97 besitzt einen langgestreckten zentralen Bereich 98, an dem beidseitig flügelartig eine der Anzahl der Verriegelungselemente entsprechende Anzahl von Schieberflügeln 99 und 100 angeformt sind, in denen den L-förmigen Nuten 84 entsprechende L-förmige Nuten 101 angeformt bzw. eingebracht sind. Wie aus Fig. 9 ersichtlich, ist der Nutgrund 102 in einer der Verschieberichtungen geneigt ausgebildet, so daß der Nutgrund in dem Bereich, der weiter von der Mittelachse M-M des Schieberelementes 97 entfernt ist, bezogen auf die Drehachse oder den Drehzapfen 24 weiter entfernt ist, als der Nutgrund 102 im Bereich 101₂ der Nut 101, der näher an der Mittellinie M-M liegt als der andere Bereich 101₁. Wenn der L-förmige Fuß 91 in der Nut 101 gleitet, dann wird gleichzeitig mit der Verriegelung eine Freigabe der Druckfeder 96 erreicht, so daß eine dauernde Nachspannung des Dichtungsdruckes der Dichtung 20 bewirkt wird.The slide element 97 has an elongated central region 98, on which on both sides a number of slide wings 99 and 100 corresponding to the number of locking elements are integrally formed, in which L-shaped grooves 101 corresponding to the L-shaped grooves 84 are formed or introduced. As can be seen from FIG. 9, the groove base 102 is inclined in one of the displacement directions, so that the groove base is further away in the region which is further away from the central axis MM of the slide element 97, with respect to the axis of rotation or the pivot pin 24. than the groove bottom 102 in the area 101₂ of the groove 101, which is closer to the center line MM than the other area 101₁. If the L-shaped foot 91 slides in the groove 101, then release of the compression spring 96 is achieved simultaneously with the locking, so that a permanent re-tensioning of the sealing pressure of the seal 20 is brought about.

Das Zahngetriebe, welches weiter oben dargestellt ist, ist in den Fig. 12 bis 14 im Detail gezeigt. Man erkennt das Schieberelement 97, an dem ein nischenartiges Abteil 103 durch senkrecht zu dem Schieberelement 97 und parallel dazu verlaufende Wände 104 und 105 abgeteilt ist. Die Fig. 12 zeigt den Antriebszapfen 75 mit dem Vierkantprofil 76 und dem Zahngetriebeelement 77. Dieses Zahngetriebelement 77 besitzt einen halbzylindrischen Bereich 106, an dem zwei Zahnsegmente 107 und 108 angeformt sind, die radial von dem Mittelpunkt des Halbzylinders 106 aus vorspringen und dadurch zwischen sich einen Einschnitt 109 aufweisen, der einem Einschnitt in einem Malteserkreuz entspricht. An der parallel zum Schieberelement 97 verlaufenden Wand sind zwei Durchbrüche 110 und 111 vorgesehen, die einen mittleren Steg 112 zwischen sich nehmen; in die Durchbrüche 110 und 11 greifen die beiden Zahnsegmente 107 und 108 ein und bei Verdrehen des Antriebszapfens 75 nehmen die Zahnsegmente 107 und 108 jeweils den Steg 112 mit, entweder nach links oder nach rechts, wodurch eine Verschiebung des Schieberelements 97 und damit eine Verstellung der Verriegelungselemente bewirkt wird.The toothed gear, which is shown above, is shown in FIGS. 12 to 14 in detail. One recognizes the slide element 97, on which a niche-like compartment 103 is divided by walls 104 and 105 running perpendicular to the slide element 97 and parallel to it. Fig. 12 shows the drive pin 75 with the square profile 76 and the toothed gear element 77. This Gear transmission element 77 has a semi-cylindrical region 106, on which two tooth segments 107 and 108 are formed, which project radially from the center of the half cylinder 106 and thereby have an incision 109 between them, which corresponds to an incision in a Maltese cross. On the wall running parallel to the slide element 97, two openings 110 and 111 are provided, which take a central web 112 between them; the two toothed segments 107 and 108 engage in the openings 110 and 11 and when the drive pin 75 is rotated, the toothed segments 107 and 108 each take the web 112 with them, either to the left or to the right, as a result of which a displacement of the slide element 97 and thus an adjustment of the Locking elements is effected.

Diese Ausführung mit den Verriegelungselementen mit Federn ist die günstigste Ausführung, da diese zum Ausgleich der Toleranzen und zur Verhinderung eines Verschlechterung der Dichtigkeit dienen.This version with the locking elements with springs is the cheapest version because they serve to compensate for the tolerances and to prevent a deterioration in the tightness.

Die Fig. 3 zeigt eine weitere Ausgestaltung der Nut, wie sie beispielsweise bei einem Verriegelungselement ähnlich dem Verriegelungselement 86 Anwendung finden könnte, an dem anstatt eines Fußes 91 ein dem Zapfen 27 entsprechender Zapfen angebracht wäre. Die Nut, hier die Nut 31, hat unterschiedliche Tiefen; dort wo der Abstand der Nut 31 von der Drehachse des Verriegelungselementes d₁ beträgt, ist die Nut 31 mit einem tieferen Abschnitt 31₁, und dort wo der kürzere Abstand d₂ ist, die Nut mit einem Abschnitt 31₂ mit geringerer Tiefe versehen. Wenn das Verriegelungselement in Verriegelungsstellung verbracht wird, dann gleitet der Zapfen 27 auf dem Nutgrund der Nut 31 (Fig. 3) entlang und gelangt aus der Freigebestellung, bei der das Verriegelungselement entgegen der Kraft der Druckfeder 86 von der Rinne 19 abgehoben ist, in die Stellung, in der die Feder 96 wirkt.FIG. 3 shows a further embodiment of the groove, as could be used, for example, in a locking element similar to locking element 86, to which a pin corresponding to pin 27 would be attached instead of a foot 91. The groove, here the groove 31, has different depths; where the distance of the groove 31 from the axis of rotation of the locking element is d 1, the groove 31 is provided with a deeper section 31 1, and where the shorter distance d 2 is, the groove is provided with a section 31 2 with a smaller depth. When the locking element is brought into the locking position, the pin 27 slides along the groove base of the groove 31 (FIG. 3) and comes out of the release position, in which the locking element is raised against the force of the compression spring 86 from the groove 19, in the position in which the spring 96 acts.

Bei den normalen Landfelgleuchten ist mit dem Schieber bzw. mit den Schieberelementen verbunden ein elektrischer Schalter (nicht näher dargestellt), mit dem die Stromzuführung zu den Leuchtstofflampen dann unterbrochen wird, wenn die Wanne geöffnet werden soll. Bei den bekannten Langfeldleuchten kann manchmal die Möglichkeit gegeben sein, daß die Schieberelemente auch bei geöffneter Wanne verschoben werden können. Die Ausführung nach Fig. 15 soll dies vermeiden. Zu diesem Zweck sind an der Wanne 18, insbesondere an der Innenseite der Rinne 19, wenigstens zwei Laschen 115 befestigt, die entlang der Seitenfläche 14 verlaufen und am inneren Ende, also an dem dem Bodenteil 12 zugewandten Ende eine L-förmige Abwinkelung 116 aufweisen. Diese Abwinkelung 116 kann ein Zapfen oder eine Feder sein, die in eine entsprechende Nut 117 oder Durchbrechung an dem Schieberelement 28 eingreifen kann. An der Innenfläche der Seitenwand 14 befinden sich pilzförmige Führungselemente (Pilze) 118, die durch je ein Langloch 119 in den Laschen 115 durchgreifen. Diese Pilze 118 dienen auch zur Führung der Laschen 115 an der Innenfläche der Seitenwand. Wenn die Wanne 18 geöffnet wird, dann wird sich die Rinne 19 von der Dichtfläche 16 des Randes 15 entfernen und zieht auf diese Weise die Laschen 115 in Pfeilrichtung Q. Dadurch gelangen die Abwinkelungen 116 in die Nuten 117 und, da ein Abheben der Wanne 18 soweit nur möglich ist, wie es der Länge der Langlöcher 119 entspricht, verbleiben die Abwinkelungen 116 in der Nut und im geöffneten Zustand der Wanne kann wegen der Zusammenwirkung zwischen Nuten 117 und Abwinkelungen 116 das Schieberelement nicht verschoben werden. Dadurch ist ein Einschalten des Schalters bei geöffneter Wanne 18 nicht möglich. Das Eingreifen der Abwinkelungen 116 in die Nuten 117 erfolgt schon dann, wenn der Abklappvorgang der Wanne gerade eingeleitet wird, damit eine "Überlistung" verhindert wird.In the normal Landfel lights, an electrical switch (not shown in more detail) is connected to the slide or to the slide elements, with which the power supply to the fluorescent lamps is interrupted when the tub is to be opened. In the case of the known linear luminaires, there may sometimes be the possibility that the slide elements can also be moved when the trough is open. 15 is intended to avoid this. For this purpose, at least two tabs 115 are attached to the tub 18, in particular on the inside of the channel 19, which extend along the side surface 14 and have an L-shaped bend 116 at the inner end, that is to say at the end facing the base part 12. This bend 116 can be a pin or a spring which can engage in a corresponding groove 117 or opening on the slide element 28. On the inner surface of the side wall 14 there are mushroom-shaped guide elements (mushrooms) 118, which each penetrate through an elongated hole 119 in the tabs 115. These mushrooms 118 also serve to guide the tabs 115 on the inner surface of the side wall. When the tub 18 is opened, the groove 19 will move away from the sealing surface 16 of the edge 15 and in this way pulls the tabs 115 in the direction of arrow Q. As a result, the bends 116 enter the grooves 117 and, since the tub 18 is lifted off as far as possible, as it corresponds to the length of the elongated holes 119, the bends 116 remain in the groove and in the open state of the tub, the slide element cannot be moved because of the interaction between the grooves 117 and bends 116. This is it is not possible to switch on the switch when the tub 18 is open. The engagement of the bends 116 in the grooves 117 already takes place when the folding process of the trough is just being initiated, so that "outwitting" is prevented.

In der Fig. 15 ist lediglich eine Lasche 115 dargestellt; selbstverständlich sind so viele Laschen vorhanden, wie es dem Gewicht der Wanne entspricht.15 only a tab 115 is shown; of course there are as many tabs as the weight of the tub.

In Fig. 15 ist angedeutet, daß die Lasche 115 bzw. die Laschen 115 an dem innenliegenden Schenkel der Rinne 19 befestigt sind. Es besteht natürlich die Möglichkeit, diese Lasche bzw. diese Laschen an der Wanne zu verrasten, beispielsweise durch entsprechende Rastnasen am Ende der Lasche 115.In Fig. 15 it is indicated that the tab 115 or the tabs 115 are attached to the inner leg of the channel 19. There is, of course, the possibility of locking this tab or these tabs on the trough, for example by means of corresponding locking lugs at the end of the tab 115.
