Description

Die Erfindung betrifft eine Einbauleuchte, die zur Aufnahme in Hohlräume, insbesondere in Hohlräume von Gebäudedecken, bestimmt ist. Eine solche Einbauleuchte ist Gegenstand des Oberbegriffs des Anspruchs 1 und im übrigen in der DE 33 29 794 A1 beschrieben.The invention relates to a recessed light which for Inclusion in cavities, especially in cavities of Ceilings, is determined. Such a downlight is Subject of the preamble of claim 1 and for the rest described in DE 33 29 794 A1.

Die Einbauhalterung der in der DE 33 29 794 A1 beschriebenen Deckeneinbauleuchte weist zur Abstützung an der Innenfläche (Hinterschnittfläche) des Hohlraums einer Gebäudedecke jeweils einen Drehriegel auf, der von einem Arm abgewinkelt ist, welcher in einer gewindelosen Buchse gehalten ist. Die gewindelose Buchse stellt den Drehlagerbereich des Drehriegels dar und ist auf dem Außengewinde eines drehgelagerten, jedoch in Axialrichtung festgelegten, Gewindeschaftes axial verstellbar angeordnet.The mounting bracket of the DE 33 29 794 A1 recessed ceiling light instructs for support the inner surface (undercut surface) of the cavity The ceiling of each building has a turnbuckle that is Arm is angled, which is in a threadless socket is held. The threadless bushing represents the pivot bearing area of the rotary bolt and is on the external thread a rotatably mounted, but fixed in the axial direction, Axially adjustable threaded shaft.

Die gewindelose Buchse gemäß der DE 33 29 794 A1 nimmt in einem Sekantialschlitz einen Federschenkel auf, der als Muttergewindeteil in das Außengewinde des Gewindeschaftes radial nachgiebig schwenkbar eingreift.The threadless socket according to DE 33 29 794 A1 takes in a secantial slot on a spring leg, which as Nut thread part in the external thread of the threaded shaft engages radially flexible pivoting.

Durch Drehung des Gewindeschaftes mittels eines Schraubwerkzeuges kann demnach die den Drehriegel tragende, den Federschenkel aufnehmende gewindelose Buchse in beiden axialen Verstellrichtungen verschoben werden, zumal der im Sekantialschlitz der gewindelosen Buchse gehaltene Federschenkel sich ständig im Eingriff mit dem Außengewinde des Gewindeschaftes befindet. By rotating the threaded shaft using a Screwing tool can accordingly the threadless bushing receiving the spring leg in both axial adjustment directions are shifted, especially since Secantial slot of the threadless bushing constantly engaged with the external thread of the Threaded shaft is located.

Wenn hingegen eine axiale Schnellverstellung des Drehriegels gemäß der DE 33 29 794 A1 vorgenommen werden soll, wird der Federschenkel außer Eingriff mit dem Außengewinde des Gewindeschaftes versetzt, indem er radial nach außen weggebogen wird. Nach Erreichen der gewünschten axialen Verstellhöhe läßt man den Federschenkel auf die Gewindeoberfläche des Gewindeschaftes zurückschnappen.If, however, an axial quick adjustment of the Rotary bolt can be made according to DE 33 29 794 A1 the spring leg is disengaged from the external thread of the threaded shaft by moving radially towards is bent outside. After reaching the desired axial Adjustment height is allowed to leave the spring leg on the thread surface snap back of the threaded shaft.

Die von der DE 33 29 794 A1 bekannte Einbauleuchte wird als verbesserungsbedürftig empfunden, weil die an sich vorteilhafte Schnellverstellung des Drehriegels eine Zweihandbetätigung erfordert, die insbesondere beim Eingriff in Deckenhohlräume Schwierigkeiten bereitet.The recessed luminaire known from DE 33 29 794 A1 is felt to be in need of improvement because of the advantageous quick adjustment of the rotary latch a two-hand operation requires, especially when engaging in Ceiling cavities are difficult.

Ausgehend von der Einbauleuchte gemäß der DE 33 29 794 A1, liegt der Erfindung die Aufgabe zugrunde, die bekannte Einbauleuchte so weiterzuentwickeln, daß sie eine handhabungssichere rasche Überführung des Drehriegels in seine die Einbauleuchte sichernde Verriegelungsposition, also dessen rasche und sichere Zustellung, gestattet.Starting from the recessed light according to the DE 33 29 794 A1, the invention is based on the object to develop the known recessed luminaire so that it a quick and easy transfer of the rotating latch in its locking position securing the recessed light, that is, its quick and safe delivery.

Entsprechend der Erfindung wird diese Aufgabe dadurch gelöst, daß das Federbauteil eine Klinke eines den Drehriegel entgegen seiner axialen Zustellrichtung sperrenden linearen Formrichtgesperres bildet.According to the invention, this object solved that the spring component is a pawl of the rotary latch locking against its axial infeed direction forms linear form locking.

Die erfindungsgemäße Einbauleuchte funktioniert in vorteilhafter Weise wie folgt:The recessed light according to the invention works in advantageously as follows:

Vor dem Einbau der Deckeneinbauleuchte ist der Drehriegel oder sind die Drehriegel der Einbauhalterung von ihrer Zustellposition distanziert und in den Umriß der Einbauleuchte hinein in ihre Entriegelungsstellung zurückgeschwenkt.Before installing the recessed ceiling light is the Twist bolts or are the twist bolts of the mounting bracket from their delivery position distanced and in the outline of the recessed light pivoted back into their unlocked position.

Sobald die Einbauleuchte durch die deckenseitige Einbauöffnung in den Deckenhohlraum hinein eingesetzt ist, wird der Drehriegel oder werden die Drehriegel in ihre Verriegelungsstellung nach außen geschwenkt und in einfacher Weise gegen die Hinterschnittfläche (Deckeninnenfläche) gezogen. Hierbei gestattet das Formrichtgesperre nur in der axialen Zustellrichtung, d.h. nur in einer Axialrichtung, eine Axialbewegung relativ zum Gewindeschaft.As soon as the recessed light through the ceiling-side installation opening is inserted into the ceiling cavity, the rotary latch or the rotary latches are in their locking position pivoted outwards and in simpler Way against the undercut surface (ceiling inner surface) drawn. Here, the form straightening lock only allows in the axial infeed direction, i.e. only in one axial direction, an axial movement relative to the threaded shaft.

Falls erwünscht, kann nach der vorbeschriebenen Zustellbewegung ein weiteres Anziehen des Drehriegels gegen die Hinterschnittfläche durch Drehung des Gewindeschaftes mittels eines Werkzeuges erfolgen. Hierzu kann die nach außen weisende Stirnseite des Gewindeschaftes nach Art eines Schraubenkopfes mit einer Werkzeugbetätigungsfläche, z.B. mit einem Schlitz- oder mit einem Innensechskant, versehen sein. Wenn der Drehriegel gelöst werden soll, geschieht dies durch Drehung des Gewindeschaftes in umgekehrter Drehrichtung (Löserichtung).If desired, you can use the one described above Incoming movement against further tightening of the rotary bolt the undercut surface by turning the threaded shaft by means of a tool. For this, the after outside face of the threaded shaft according to Art a screw head with a tool operating surface, e.g. with a slotted or with an internal hexagon be. If the twist lock is to be released, this is done by turning the threaded shaft in reverse Direction of rotation (release direction).

In weiterer Ausgestaltung der Erfindung ist das Federbauteil eine einseitig im Drehriegel eingespannte Blattfeder, welche mit ihrer freien kurzen Randkante in das Außengewinde eingreift, wobei zumindest der freie Endbereich der Blattfeder mit einer Mantellinie des Gewindeschaftes einen spitzen Winkel bildet, dessen Winkelöffnung in Zustellrichtung zeigt. Diese erfindungsgemäße Ausführungsform bietet eine höchst einfache Bauform, da die Sperrklinke aus einer Blattfeder besteht. In a further embodiment of the invention, the spring component a leaf spring clamped on one side in the rotary latch, which with its free short edge into the external thread engages, at least the free end region of the Leaf spring with a surface line of the threaded shaft one forms an acute angle, its angular opening in the feed direction shows. This embodiment according to the invention offers a very simple design, since the pawl consists of one Leaf spring exists.

Das die Klinke eines linearen Formrichtgesperres bildende erfindungsgemäße Federbauteil besitzt in jedem Falle die Funktion einer mit dem Gewindeschaft im Gewindeeingriff befindlichen Gewindemutter, welche gegen Drehung gesichert ist. Auf diese Weise kann das im Drehriegel gehaltene Federbauteil je nach Drehung des Gewindeschaftes den Drehriegel nach Art eines Gewindetriebs axial verschieben.The one that forms the pawl of a linear form locking mechanism has spring component according to the invention in any case the function of one with the threaded shaft in threaded engagement located threaded nut, which secured against rotation is. In this way, what is held in the rotary latch Spring component depending on the rotation of the threaded shaft Move the locking bolt axially in the manner of a screw drive.

Der Gewindeeingriff des von einer Blattfeder gebildeten Federbauteils kann dadurch verbessert werden, daß die freie kurze Randkante der Blattfeder eine an die Außenkontur des Gewindeschaftes angepaßte Aussparung darstellt, welche beispielsweise eine runde oder V-förmige Innenkontur aufweisen kann.The thread engagement of the formed by a leaf spring Spring component can be improved in that the free short edge of the leaf spring one on the outer contour represents a recess of the threaded shaft, which, for example, has a round or V-shaped inner contour can have.

Eine andere vorteilhafte erfindungsgemäße Variante besteht darin, daß der Drehriegel über einen von seiner axialen Zustellposition entfernten Axialbereich in seine Verriegelungsstellung schwenkbar und über einen der axialen Zustellposition benachbarten Axialbereich von mindestens sich einer parallel zum Gewindeschaft erstreckenden axialen Führungsfläche in seiner Verriegelungsstellung gehalten ist.Another advantageous variant according to the invention is that the rotary latch over one of its axial infeed position removed in its axial range Locking position pivotable and one of the axial Infeed position adjacent axial area of at least extending axially parallel to the threaded shaft Guide surface held in its locked position is.

Entsprechend der vorbeschriebenen bevorzugten erfindungsgemäßen Ausführungsform ist der Drehriegel über einen von seiner axialen Zustellposition entfernten Axialbereich in seine Verriegelungsstellung schwenkbar und aus dieser Verriegelungsstellung in seine Entriegelungsstellung zurückschwenkbar. According to the preferred invention described above The rotary latch is one embodiment axial area distant from its axial infeed position pivotable into and out of its locking position Locked position in its unlocked position swiveling back.

Sobald der Drehriegel durch eine einfache Zugbewegung in seinen axialen Zustellbereich hineingelangt, wird mittels der sich parallel zum Gewindeschaft erstreckenden axialen Führungsfläche eine Zwangsführung bewirkt, welche den Drehriegel in seiner ausgeschwenkten Verriegelungsstellung hält, was der Sicherheit der gesamten Anordnung zugute kommt.As soon as the twist lock with a simple pull movement to get into its axial infeed area is by means of the extending parallel to the threaded shaft axial guide surface causes a positive guide, which the rotary latch in its swung-out locking position holds, which benefits the safety of the entire arrangement is coming.

Die axiale Länge der der axialen Zustellposition benachbarten axialen Führungsfläche ist so bemessen, daß sie die Dickenunterschiede zumindest von gängigen Deckenpaneelen berücksichtigt.The axial length of the axial infeed position adjacent axial guide surface is dimensioned so that the thickness differences at least from common ceiling panels considered.

Eine weitere sehr vorteilhafte erfindungsgemäße Ausführungsform besteht darin, daß der Drehriegel entgegen Federrückstellkraft in seine Entriegelungsstellung schwenkbar ist. Dies bedeutet umgekehrt, daß der Drehriegel während des Einsetzens der Einbauleuchte in den Einbauhohlraum hinein von Hand in seiner Entriegelungsstellung gehalten wird und in seine Verriegelungsstellung ausschwenkt, sobald der Drehriegel losgelassen wird.Another very advantageous embodiment of the invention is that the rotary bolt counter Spring return force can be pivoted into its unlocked position is. Conversely, this means that the rotary latch during inserting the recessed luminaire into the recessed cavity held by hand in its unlocked position and swings out into its locked position as soon as the rotary latch is released.

Weitere Erfindungsmerkmale sind zusätzlichen Unteransprüchen zu entnehmen.Further features of the invention are additional subclaims refer to.

    Der Leuchtenkörper 12 verfügt über einen kreisrunden Rahmen 15, welcher von einem Bügel 16 überbrückt ist. Von dem nur teilweise dargestellten Bügel 16 sind lediglich dessen Bügelsteg 17 und dessen einer Bügelschenkel 18 in Fig. 1 dargestellt. Jeder Bügelschenkel 18 ist mittels einer Befestigungsstelle 19 mit dem Rahmen 15 verbunden.The lamp body 12 has a circular Frame 15, which is bridged by a bracket 16. From the only partially shown bracket 16 are only whose strap web 17 and one of a strap leg 18 in Fig. 1 shown. Each bracket leg 18 is by means of an attachment point 19 connected to the frame 15.

    Der Rahmen 15 weist einen Flansch 20 auf, der sich an der Außenfläche 21 eines Deckenpaneels 22 abstützt, dessen Innenfläche (Hinterschnittläche) die Bezugsziffer 23 trägt.The frame 15 has a flange 20 which is attached the outer surface 21 of a ceiling panel 22 supports the Inner surface (undercut surface) bears the reference number 23.

    Mittels einer Halteaussparung 24 des Rahmens 15 und einer Durchstecklasche 25 des Bügelschenkels 18 ist eine Schraube 26 entlang ihrer Längsmittelachse L unverschieblich gehalten und überdies um ihre Längsmittelachse L drehbar gelagert.By means of a holding recess 24 in the frame 15 and a push-through tab 25 of the bracket leg 18 is one Screw 26 is immovable along its longitudinal central axis L. held and also rotatable about its longitudinal central axis L. stored.

    Die Axialsicherung der Schraube 26 erfolgt dadurch, daß deren Schraubenkopf 27 sich an einem Anschlag 28 des Rahmens 15 abstützt, während am oberen Ende des Gewindeschaftes G, dessen Außengewinde mit 29 bezeichnet ist, eine Gewindemutter 30 zur Axialsicherung der Schraube 26 vorgesehen ist. Anstelle der Gewindemutter 30 könnte auch ein Seegerring, ein Splint oder eine Kunststoffkappe verwendet werden.The axial securing of the screw 26 takes place that the screw head 27 on a stop 28 of the Frame 15 supports while at the upper end of the threaded shaft G, whose external thread is designated 29, a Threaded nut 30 is provided for axially securing the screw 26 is. Instead of the threaded nut 30 could also Seegerring, a split pin or a plastic cap used will.

    Zu ihrer Montage wird die Schraube 26 mit dem vorderen freien Ende 31 ihres Gewindeschaftes G voran vor Montage des Leuchtenkörpers 12 etwa in Radialrichtung r zunächst durch die Halteaussparung 24 hindurch und sodann durch die Durchstecklasche 25 geführt und dort mittels der Gewindemutter 30 gesichert.To assemble the screw 26 with the front Free end 31 of their threaded shaft G ahead before assembly of the lamp body 12 initially in the radial direction r through the holding recess 24 and then through the Push-through tab 25 guided and there by means of the threaded nut 30 secured.

    Bevor das freie Ende 31 des Gewindeschaftes G durch die Durchstecklasche 25 hindurchgeführt wird, werden zunächst die beiden Drehriegel D mit ihren glatten Lagerlöchern 33 und zugleich der zentrale Wicklungsbereich 35 einer Schenkelfeder 39 auf den Gewindeschaft G aufgesteckt.Before the free end 31 of the threaded shaft G through the push-through tab 25 is passed through first the two rotary latches D with their smooth bearing holes 33 and at the same time the central winding area 35 a leg spring 39 is attached to the threaded shaft G.

    Die Lagerlöcher 33 sind in Gabelschenkel 34 der Drehriegel D eingeformt. Die Drehriegel D bestehen zweckmäßig aus Kunststoffspritzguß.The bearing holes 33 are in the fork leg 34 of the Twist lock D molded in. The rotary latches D are useful made of injection molded plastic.

    In einem Flügel 32 eines Drehriegels D ist in einer winkelförmigen Einlegeöffnung 36 ein Federbauteil F, und zwar eine Blattfeder gehalten, welche einen freien geraden Federschenkel S besitzt. Der Federschenkel S schließt mit der Mantellinie M des Gewindeschaftes G einen spitzen Winkel α ein, dessen Winkelöffnung O in die axiale Zustellrichtung Z der Drehriegel D weist.In a wing 32 of a rotary latch D is in one angular insertion opening 36 a spring component F, and Although a leaf spring is held, which is a free straight Spring leg S owns. The spring leg S also closes the surface line M of the threaded shaft G an acute angle α a, the angular opening O in the axial feed direction Z the rotary latch D points.

    Die Funktion der gezeigten Einbauhalterung 11 ist folgende:The function of the mounting bracket 11 shown is as follows:

    Vor dem Einsetzen der Deckeneinbauleuchte 10 durch die Einbauöffnung 37 des Deckenpaneels 22 hindurch werden die beiden Drehriegel D entgegen der Rückstellkraft der beiden geraden Federenden 38 der Schenkelfeder 39 mit den Fingern einer Hand in Richtung der Pfeile u so weit nach innen geschwenkt, daß die Einbauhalterung 11 durch die Einbauöffnung 37 hindurch in den Deckenhohlraum H eingesetzt werden kann. Bei dieser Maßnahme ist der Leuchtenkörper 12 noch nicht an der Einbauhalterung 11 befestigt. In dieser Montagestellung befinden sich die Drehriegel D zunächst noch in ihrer Entriegelungsstellung.Before inserting the recessed ceiling light 10 through the Installation opening 37 of the ceiling panel 22 through the two rotary latches D against the restoring force of the two straight spring ends 38 of the leg spring 39 with the fingers one hand in the direction of the arrows u so far inward pivoted that the mounting bracket 11 through the mounting opening 37 can be inserted into the ceiling cavity H. can. With this measure, the lamp body 12 is still not attached to the mounting bracket 11. In this assembly position the rotary latches D are initially still in their unlocked position.

    Sodann werden beide Drehriegel D des Drehriegelpaares P losgelassen, so daß die beiden Federenden 38 ihre zugehörigen Drehriegel D entsprechend den Pfeilen v in ihre Verriegelungsstellung (Fig. 1 und 3) versetzen.Then both latches D of the pair of latches P released so that the two spring ends 38 their associated Turning latch D according to the arrows v into its locking position (Fig. 1 and 3) move.

    Sodann übergreifen die Finger der Bedienungshand das Drehriegelpaar P oberseitig und ziehen dieses entlang der Zustellrichtung Z so weit nach unten, bis die Riegelfläche 40 eines jeden Flügels 32 auf der Innenfläche 23 des Paneels 22 aufliegt. Diese ungehinderte Zustellbewegung in axialer Zustellrichtung Z ist möglich, weil das Federbauteil F mit seinem Federschenkel S eine federnde Klinke eines linearen Formrichtgesperres bildet. Der Federschenkel S verhindert also zugleich eine axiale Öffnungsbewegung der Drehriegel D in Öffnungsrichtung A.Then the fingers of the operating hand reach over it Pair of rotary latches P on top and pull them along the Infeed direction Z down until the locking surface 40 of each wing 32 on the inner surface 23 of the Panels 22 rests. This unimpeded delivery movement in axial feed direction Z is possible because the spring component F with its spring leg S a resilient pawl of a linear form locking mechanism. The feather leg S thus prevents an axial opening movement of the Quarter-turn lock D in opening direction A.

    Soll eine Öffnungsbewegung der Drehriegel D in Richtung A bewirkt werden, so kann dies nur dann geschehen, wenn die Schraube 26 in entsprechender Drehrichtung um ihre Längsmittelachse L verdreht wird. Hierbei übernimmt der Federschenkel S die Funktion einer Gewindemutter wie bei einem Gewindetrieb und nimmt dabei beide Drehriegel D mit, zumal zwischen beiden Drehriegeln D ein Formschluß bezüglich beider axialer Richtungen Z und A herrscht, da die Gabelschenkel 34 radial ineinandergreifen.Should an opening movement of the rotary latch D in the direction A can be effected, this can only happen if the screw 26 in the corresponding direction of rotation about their Longitudinal central axis L is rotated. Here the Spring leg S the function of a threaded nut as in a screw drive and takes both rotary latches D with it, especially since there is a positive connection between the two locking bolts D. in both axial directions Z and A, since the Fork legs 34 engage radially.

    Gemäß der in den Fig. 1 und 3 gezeigten Zustellposition sind die beiden Drehriegel D gegen ein Zurückschwenken in Richtung der Pfeile u gesperrt, da über einen der axialen Zustellposition benachbarten Axialbereich zwei axiale Führungsflächen 41 vorhanden sind. Diese axialen Führungsflächen 41 erstrecken sich nur über eine axiale Teilhöhe des Gewindeschaftes G. Die axiale Teilhöhe berücksichtigt unterschiedliche Dicken gängiger Deckenpaneele 22.According to the delivery position shown in FIGS. 1 and 3 are the two rotary latches D against swinging back locked in the direction of arrows u because of one of the axial Infeed position adjacent axial area two axial Guide surfaces 41 are present.
