Description

Die Erfindung bezieht sich auf eine Halterungseinrichtung zur lösbaren, klirrfreien Befestigung der Schalen elektrischer Wand- oder Deckenleuchten an einem Träger mit einen nach außen überstehenden Randflansch des Halses der Schale untergreifenden radial federnden Haltevorsprüngen, von denen wenigstens einer als um eine zur Abzugsrichtung senkrechte Achse aus einer öffnung des Trägerrandes nach außen schwenkbarer, mit einem Hakenteil an den Hals federndes und mit einem i.w. radial nach außen ragenden Entriegelungsarm versehenes Blattfeder-Arretierglied ausgebildet ist.The invention relates to a mounting device for detachable, clink-free attachment of the shells of electrical wall or ceiling lights to a support with an outwardly projecting edge flange of the neck of the shell engaging radially resilient retaining projections, at least one of which as an axis perpendicular to the withdrawal direction from a Opening of the carrier edge can be pivoted outwards, with a hook part resilient to the neck and with an iw radially outwardly projecting unlocking arm provided leaf spring locking member is formed.

Eine derartige, aus der deutschen Offenlegungsschrift 29 28 495 bekannt gewordene Halterungseinrichtung ermöglicht bei einfachem Aufbau und einfacher Betätigbarkeit, insbesondere auch im Hinblick auf die Erkennbarkeit der Art und Weise, wie die Entriegelung erfolgen muß, eine klirrfreie, sichere Halterung, auch unter Berücksichtigung der relativ großen Fertigungstoleranz im Halsdurchmesser der Schalen.Such a mounting device, which has become known from German Offenlegungsschrift 29 28 495, enables simple, secure mounting, also with regard to the relative ease, with simple construction and simple actuation, in particular also with regard to the recognizability of the way in which the unlocking must take place large manufacturing tolerance in the neck diameter of the shells.

Ähnlich wie bei anderen derartigen Halterungseinrichtungen mit federnden Arretiergliedern können dabei allerdings Schwierigkeiten insbesondere dann auftreten, wenn bei Befestigung an einer Wand das federnde Arretierglied unten zu liegen kommt, so daß durch das Gewicht der Schale die Gefahr eines Nachaußendrückens der Blattfeder und damitdie Gefahr eines Herausfallens der Schale gegeben ist. Diese Schwierigkeit ließe sich zwar vermeiden, wenn entweder kein federndes Arretierglied vorgesehen wird, was aber im Hinblick auf den Ausgleich der Fertigungstoleranzen nachteilig ist, oder aber wenn man die Montage so vornimmt, daß das federnde Arretierglied oben liegt, was aber im praktischen Gebrauch nicht gewährleistet werden kann, und insbesondere dann nicht, wenn die Leuchte von Laien montiert wird.Similar to other such mounting devices with resilient locking members, difficulties can arise, in particular, if the resilient locking member comes to rest at the bottom when attached to a wall, so that the weight of the shell increases the risk of the leaf spring being pushed outward and thus the risk of the leaf spring falling out Shell is given. This difficulty could be avoided if either no resilient locking member is provided, but this is disadvantageous with regard to the compensation of the manufacturing tolerances, or if the assembly is carried out so that the resilient locking member is on top, but this does not guarantee practical use can, and especially not if the lamp is installed by laymen.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Halterungseinrichtung der eingangs genannten Art so auszugestalten, daß bei gleichbleibend einfachem und leicht betätigbaren Aufbau die Gefahr eines Entriegelns auch bei extrem schweren Schalen und unter beliebigen Montagebedingungen verhindert ist.The invention is therefore based on the object of designing a mounting device of the type mentioned in such a way that the risk of unlocking, even with extremely heavy shells and under any assembly conditions, is prevented with a consistently simple and easy-to-operate structure.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß am Kopf des Blattfeder-Arretiergliedes eine ihn überragende, bei Verschwenkung des Blattfeder-Arretiergliedes an der öffnungsbegrenzung des Trägerrandes anstoßende ausgebogene Arretierzunge angeordnet ist, die durch Drücken auf ihren vor dem Entriegelungsarm verlaufendes freies Ende in eine Freigabestellung verschwenkbar ist.To achieve this object, it is provided according to the invention that at the head of the leaf spring locking member a protruding, when the leaf spring locking member pivots against the opening limit of the support edge bent locking tongue is arranged, which by pressing on its free end running in front of the unlocking arm in a release position is pivotable.

Durch diese zusätzliche Arretierzunge kann bei extrem schwerem Gewicht und der bereits genannten ungünstigen Montagestellung die Schale das Blattfeder-Arretierglied nur soweit nach außen schwenken, bis die überstehende Ausbiegung der Arretierzunge am Rand der öffnung des Trägerrandes anstößt. Auch durch beliebig hohe Kräfte ist dann eine Weiterverschwenkung nicht möglich und somit die vorstehend beschriebene Gefahr einer selbsttätigen Entriegelung sicher verhindert. Zum Zwecke des gewollten Lösens der Halterungseinrichtung muß die Bedienungsperson auf den Entriegelungsarm des Blattfeder-Arretiergliedes drücken, wobei zwangsläufig das, im wesentlichen parallel vor ihm verlaufende freie Ende der Arretierzunge mitbetätigt wird, die auf diese Art und Weise quasi in die Höhe des Kopfs des Blattfeder-Arretiergliedes zurückverschwenkt wird, so daß die vorstehende zusätzliche Verriegelung außer Betrieb gesetzt ist. Es steht nunmehr kein Teil mehr soweit vor, daß es hinter der Begrenzung der Ausschwenköffnung im Trägerrand anstoßen könnte, so daß im Zuge der weiteren Verschwenkung das Blattfeder-Arretierglied den Halsabschnitt der Schale freigibt, die damit aus ihrem Sitz im Träger herausgehoben werden kann.With this additional locking tongue, the shell can only pivot the leaf spring locking member outward in the case of extremely heavy weight and the aforementioned unfavorable mounting position until the protruding bend of the locking tongue hits the edge of the opening of the carrier edge. A further pivoting is then not possible even by any high forces and thus the risk of automatic unlocking described above is reliably prevented. For the purpose of deliberately loosening the mounting device, the operator must press the unlocking arm of the leaf spring locking member, the free end of the locking tongue, which essentially runs parallel to it, is inevitably also actuated, which in this way is virtually at the level of the head of the leaf spring - Locking member is pivoted back so that the above additional locking is deactivated. There is no longer any part so far that it could abut behind the limitation of the pivoting opening in the carrier edge, so that in the course of the further pivoting the leaf spring locking member releases the neck portion of the shell, which can thus be lifted out of its seat in the carrier.

Neben der selbstverständlich ebenfalls gegebenen Möglichkeit die Arretierzunge als gesondertes Bauteil am Blattfeder-Arretierglied - insbesondere durch Punktschweißen - zu befestigen, hat es sich als besonders zweckmäßig erwiesen, beide als einstückiges Bauteil derart auszubilden, daß die Arretierzunge ein aus der Blattfeder ausgebogenes Stanzteil ist. Vor dem Biegen des Blattfeder-Arretiergliedes wird es mit einer zweckentsprechend angeordneten U-förmigen Längausstanzung versehen, die in anderer Weise als das eigentliche Blattfederelement gebogen wird, um die besondere zusätzliche Arretierzunge zu bilden.In addition to the possibility of fixing the locking tongue as a separate component on the leaf spring locking element - in particular by spot welding - it has proven particularly expedient to design both as a one-piece component in such a way that the locking tongue is a stamped part bent out of the leaf spring. Before the leaf spring locking member is bent, it is provided with an appropriately arranged U-shaped longitudinal punching, which is bent in a different way than the actual leaf spring element in order to form the special additional locking tongue.

Schließlich liegt es auch noch im Rahmen der Erfindung, daß die Blattfeder ein doppellagiges Biegeteil ist, dessen übereinanderliegende, am Bodenabschnitt des Trägers befestigte Abschnitte,zumindest im Kopf-und Hakenbereich voneinander beabstandet sind. Diesesdoppellagige Biegeteil ermöglicht eine Einstellung der Gesamtfederhärte des so gebildeten Arretiergliedes im weiten Umfang unabhängig von der Federkraft des verwendeten Bandmaterials, so daß je nach den Gegebenheiten nur durch entsprechende Biegung eine optimale Anpassung an de gewünschten Betriebsbedingungen, insbesondere auch an das abzufangende Gewicht der Schale erzielt werden kann.Finally, it is also within the scope of the invention that the leaf spring is a double-layer bent part, the superimposed sections of which are fastened to the bottom section of the carrier and are spaced apart from one another, at least in the head and hook area. This double-layered bending part enables the total spring hardness of the locking member thus formed to be adjusted to a large extent independently of the spring force of the strip material used, so that, depending on the circumstances, optimum adaptation to the desired operating conditions, in particular also to the weight of the shell to be intercepted, can only be achieved depending on the circumstances can.

Further advantages, features and details of the invention result from the following description of an exemplary embodiment and from the drawing. Show:
  • 1 is a partially broken side view of a wall or ceiling lamp according to the invention,
  • 2 is a broken top view of the carrier with the shell removed,

Die Schale 1 der in Fig. 1 dargestellten Wand- oder Deckenleuchte weist einen verjüngten Halsabschnitt 2 mit einem überstehenden Randflansch 3 auf, der einerseits durch zwei im Umfang um etwa 120° versetzte federnde Haltevorsprünge 4 (vgl. insb.Fig.2 u.Fig. 4) und andererseits von einem Blattfeder-Arretierglied 5, der gegenüber den beiden Haltevorsprüngen 4 jeweils um wiederum 120° versetzt am Umfang angeordnet ist, untergriffen wird. Die Haltevorsprünge 4 sind entsprechend abgewinkelte Blattfedern, die in einer Stanzausbiegung 6 mit ihrem Schenkel 7 verklemmt sind, wobei eine ausgebogene, abgewinkelte Steckbegrenzungszunge 8 einen Einsteckbegrenzungsanschlag beim Einsetzen dieses Blattfederbauteils vor dem Verklemmen der Stanzausbiegung 6 bildet. Das Blattfeder-Arretierglied 5, welches zum Freigeben des Randflansches 3 der Schale 1 aus einer öffnung 9 des Randes 10 des an der Wand oder Decke befestigten Trägers 11 herausverschwenkt werden kann, ist als doppellagiges Biegeteil ausgebildet. Die beiden Abschnitte 5a und 5b sind dabei zumindest im Bereich des Kopfes 12 und des den Randflansch 3 untergreifenden Hakens 13, im dargestellten Ausführungsbeispiel auch im Bereich des Entriegelungsarms 14 voneinander beabstandet, wobei die Art der Beabstandung eine weitgehende Einflußmöglichkeit auf die Federkraft dieses Arretiergliedes 5 zuläßt. Durch eine U-förmige Ausstanzung 15 im Bereich des Kopfes 12 und des Entriegelungsarms 14 ist eine Arretierzunge 16 gebildet, die so gebogen ist, daß ihr über den Kopf 12 des Blattfeder-Entriegelungsgliedes 5 überstehender Biegeabschnitt 17 beim Nachaußenverschwenken des Arretiergliedes 5 an der Randbegrenzung 18 der Ausschwenköffnung 9 des Randes 10 des Trägers 11 anstößt. Damit ist ein selbsttätiges öffnen des Arretiergliedes 5 infolge sehr starker Zugkräfte an der Schale, beispielsweise durch deren hohes Gewicht, insbesondere aber einer gegenüber Fig. 1 um 90° verdrehten Wandbefestigung, so daß das Arretierglied 5 unten zu liegen kommt, ausgeschlossen. Beim Drücken auf den Entriegelungsarm 14 in Richtung des Pfeils 20 muß zwangsläufig das freie Ende 21 der Arretierzunge zunächst gegen den Entriegelungsarm 14 verschwenkt werden, wodurch die vorspringende Biegung 17 praktis.ch in die Höhe des Kopfes 12 des Blattfeder-Entriegelungsgliedes 5 zurückbewegt wird. Bei der Weiterbewegung kann nunmehr der Entriegelungsarm 14 gegen die Decke oder die Wand bewegt werden, wodurch der infolge des Zurückziehens der Arretierzunge entriegelte Kopf 12 aus der öffnung 9 herausschwenken kann (vgl. Fig. 5). Damit wird der Randflansch 3 des Halses . 2 der Schale 1 frei und die Schale kann vom Träger 11 abgezogen werden. Die beiden Abschnitte 5a und 5b des doppellagigen Biegeteils des Blattfeder-Arretiergliedes 5 sind bevorzugt mit Hilfe einer ausgebogenen, nachträglich verdrückten Klemmlasche 22 am Boden 23 des Trägers 11 befestigt.The shell 1 of the wall or ceiling lamp shown in FIG. 1 has a tapered neck section 2 with a protruding edge flange 3 which, on the one hand, has two resilient retaining projections 4 which are offset by approximately 120 ° in circumference (cf. especially Fig. 2 and Fig. 4) and on the other hand by a leaf spring locking member 5, which is arranged in relation to the two holding projections 4, each offset by 120 ° on the circumference. The holding projections 4 are correspondingly angled leaf springs, which are clamped in a stamped bend 6 with their legs 7, a bent, angled pin limiting tongue 8 forming an insert limit stop when inserting this leaf spring component before the pin bend 6 is jammed. The leaf spring locking member 5, which can be pivoted out of an opening 9 of the edge 10 of the support 11 fastened to the wall or ceiling in order to release the edge flange 3 of the shell 1, is designed as a double-layer bent part. The two sections 5a and 5b are spaced apart from one another at least in the area of the head 12 and the hook 13 engaging under the edge flange 3, in the illustrated embodiment also in the area of the unlocking arm 14, the type of spacing permitting the spring force of this locking member 5 to be largely influenced . A U-shaped punching 15 in the area of the head 12 and the unlocking arm 14 forms a locking tongue 16 which is bent in such a way that its bending section 17 protruding beyond the head 12 of the leaf spring unlocking member 5 when the locking member 5 pivots outward at the edge 18 the pivot opening 9 of the edge 10 of the carrier 11 abuts. An automatic opening of the locking member 5 as a result of very strong tensile forces on the shell, for example due to its high weight, but in particular a wall fastening rotated by 90 ° with respect to FIG. 1, so that the locking member 5 comes to lie below, is excluded. When pressing the unlocking arm 14 in the direction of arrow 20, the free end 21 of the locking tongue must inevitably first be pivoted against the unlocking arm 14, as a result of which the projection bend 17 Praktis.ch is moved back into the height of the head 12 of the leaf spring unlocking member 5. When moving further, the unlocking arm 14 can now be moved against the ceiling or the wall, as a result of which the head 12 unlocked as a result of the retraction of the locking tongue can pivot out of the opening 9 (cf. FIG. 5). So that the edge flange 3 of the neck. 2 of the shell 1 free and the shell can be removed from the carrier 11. The two sections 5a and 5b of the double-layer bent part of the leaf spring locking member 5 are preferably fastened to the bottom 23 of the carrier 11 with the aid of a bent-out, subsequently compressed clamping tab 22.

Die Erfindung ist nicht auf das dargestellte Ausführungs- Deispiel beschränkt. Wesentlich ist lediglich das Vorsehen einer zusätzlichen Verriegelungsfeder, die durch Anstoßen am Rand der Ausschwenköffnung des Trägerrandes eine ungewollte Entriegelung des Arretiergliedes durch ungünstige Montageverhältnisse oder hohes Gewicht der Schale verhindert und die automatisch vor der gewollten Betätigung des Arretiergliedes entriegelt wird. Hierzu könnte beispielsweise auch eine gesonderte, am Blattfeder-Arretierglied 5 angeschweißte, oder sonstwie befestigte Arretierzunge verwendet werden.The invention is not limited to the illustrated exemplary EXAMPLE D. All that is essential is the provision of an additional locking spring which, by bumping against the edge of the pivoting opening of the carrier edge, prevents an undesired unlocking of the locking member by unfavorable assembly conditions or high weight of the shell and which is automatically unlocked before the locking member is actuated intentionally. For this purpose, for example, a separate locking tongue welded to the leaf spring locking member 5 or otherwise secured could also be used.
