Definitions
- the invention relates to a luminaire according to the preamble of claim 1.
- Such luminaires in the holder of which a rotary adjustment device is incorporated, have become well known through prior public use.
- a simple type of such rotary adjustment devices can consist of two mounting parts, the two rotary adjustment parts, which can be rotated relative to one another about a common axis of rotation and can be pressed against one another by means of a thread. This is to rotary adjusting devices with flat swivel joints that allow usually a peripheral adjustment of nearly 360 o. If a luminaire holder has two such rotary adjustment devices with mutually perpendicular rotating planes, the lamp holder fitting carried by the luminaire holder can be oriented in a spatially articulated manner.
- Luminaires of the genus according to the invention can, for example, be mounted on busbar adapters, at point outlets or on supporting structures, such as be attached to truss parts.
- Luminaires meanwhile represent technically complex luminaire systems consisting of various interchangeable modules, which place particularly high demands on the mechanical stability of the luminaire bracket, which means that hitherto usual rotary adjustment devices mostly can not meet.
- the object of the invention is to improve its mounting, in particular its rotary adjustment device, in such a way that it can safely accommodate large load torques of heavy lighting systems with exact adherence to the selected adjustment position.
- a rotary adjustment part forms an approximately strip-shaped circular path element with force or form-locking means, which cooperate with force or form-lock means of the other rotary adjustment part, which is held away from the axis of rotation by means of at least one spacer.
- a strip-shaped circular path element is held so far away from the axis of rotation by means of at least one spacer and thereby a lever arm is formed which enables large load moments of asymmetrically structured lighting systems to be safely intercepted.
- the force or positive locking means of the other rotary adjustment part which interacts with the force or positive locking means of the strip-shaped circular path element, is offset to the same extent away from the axis of rotation.
- the circular path elements according to the invention can - depending on the application - either over the entire Circumference, ie the full circle, or only extend over a partial circumference, ie over a partial circle.
- the circular path element can have a flat circular path in that the circular path element is at least part of a circular ring disk with at least one circular ring surface carrying the force or form-locking means.
- the invention provides that the circular path element is curved in a circular manner in that it is at least part of a hollow circular cylinder with at least one cylinder jacket surface that carries the force or form-locking means.
- the positive locking means can be designed so that the circular path element has a toothing in which at least one counter tooth of the other rotary adjustment part can engage in a rotationally locking manner.
- This solution according to the invention can also include an embodiment in which the respective opposing tooth is part of an adjusting pinion that rolls on the toothing of the circular path element.
- This adjustable toothed pinion is expediently designed to be self-locking due to the tooth geometry. In any case, it is advantageous if the circular path element has teeth over its entire circumferential length.
- the circular path element forms a braking surface, preferably over its entire circumferential length which at least one counter-braking element of the other rotary adjustment part can be pressed in a rotationally locking manner.
- the counter-braking element could be clamped to the circular path element approximately in the form of pliers.
- the design of the spacer can be about a spoke or a disc wheel.
- the spacer with its spoke or disc wheel-like design can either extend over a full circle or only over a circular sector. In the case of a circular sector, the circular path element would have a segment-like shape.
- the spacer in a further embodiment of the invention, it is also possible for the spacer to be detached from a lamp housing part that also defines the axis of rotation, e.g. is formed by a transformer housing.
- the lamp according to the invention is particularly suitable for being easily and precisely reproducibly adjusted.
- the circular path element carries a scale according to the invention, while the other rotary adjustment part forms a pointer which cooperates with the scale.
- each luminaire - regardless of the specific embodiment - is provided with the reference number 10 overall.
- the lamp holder 13 is located between its feed part, a busbar adapter 11, and its lamp holder fitting 12 for receiving a lamp (not shown), for example a plunger lamp.
- Two rotary adjustment devices A and B are incorporated into the holder 13.
- the rotation adjustment device A is assigned the rotation axis y and the rotation adjustment device B the rotation axis x.
- a rotary plate 14 is connected in a rotationally fixed manner to the adapter 11 by way of its hub-shaped central part 15.
- Spokes 16 integrally formed radially outward extend from the hub-shaped central part 15, which pass into a relatively high annular disk 17, which has a relatively small radial extent.
- the circular disk 17 represents an annular surface 18 which has a toothing 19, the tooth flanks of which extend essentially radially to the axis of rotation y.
- a hollow rivet-like component 22 rotatably connects the spatially fixed hub-shaped central part 15 and a hub-shaped central part 23 of a mounting arm 24 in the manner of a flat joint.
- Can not be exceeded in a known rotation restriction means 25 ensure that a rotation angle of 360 o y with respect to the axis of rotation.
- the circular ring surface 18 with its toothing 19 represents a strip-shaped circular path element, which is kept far from the axis of rotation y by spacers, namely through the spokes 16.
- the annular surface 18 is held spatially fixed with its toothing 19 on the adapter 11.
- a toothed pinion 30 engages in the toothing 19 of the circular ring surface 18 and is supported by the collar 26 of a bearing bolt provided with a thread 27 at the other end 28 is secured against axial displacement.
- the bearing pin 28 is secured against rotation by means of a flat 29 in the central pin shaft area in connection with a corresponding counter surface within the through hole 31 of the bearing bracket 32 of the mounting arm 24.
- the toothed pinion 30 meshing with the toothing 19 can be pressed by tightening the knurled nut 33 with a radial clamping surface 34 against a radial counter surface 35 of the bracket 32 and thus prevented from rotating.
- the bracket arm 24 is blocked by a very large lever arm with respect to its rotation about the axis of rotation y.
- the rotary adjustment device B functions in a fundamentally similar manner to the rotary adjustment device A.
- a difference is that the circular path element 36 represents the inner circumferential surface of a hollow circular cylinder.
- a toothing 19 is also provided on the inner cylinder surface 36, the tooth flanks of which advantageously extend parallel to the axis of rotation x.
- the arrangement of the pinion 30 with the bearing pin 28 is fundamentally similar in function and design to that of the rotary adjustment device B. Only the bearing pin 28 does not have a flattened portion for the purpose of securing it against rotation within the bearing bracket 32, but instead has a split lock pin 38 penetrating it in a radial bore 37. The anti-rotation split pin 38 is secured in position in a receiving space 39 of the console 32.
- the rotary adjustment device B functions as follows:
- the bracket arm 40 is blocked with respect to its rotation about the axis of rotation x.
- scale parts S are also indicated adjacent to the circular path elements 18 and 36 of the rotary adjustment devices A and B, each of which cooperates with a pointer-like extension 41 of the relevant bearing bracket 32. In this way, a certain setting position of the arrangement is easy to reproduce.
- the adjustment devices A and B of the embodiment according to FIGS. 5 and 6 do not fundamentally differ from the embodiment according to FIGS. 1-4. The only difference is that in the rotary adjustment device B of FIGS. 1-4 spokes 16 form the spacers between the axis of rotation x and the circular path element 36.
- a transformer housing 42 represents, as it were, the spacer which distances the segment arc 43 from the axis of rotation x.
- the transformer housing 42 also defines the axis of rotation x by means of a pivot bearing attachment 44.
- the transformer housing 42 partially takes over Function of the lamp holder. Namely, the transformer housing 42 replaces the bracket arm 24 according to the embodiment of FIGS. 1-3.
- the bracket 32 assigned to the turntable 14 (see FIG. 5) for holding the pinion 30 is therefore - like the hub-shaped middle part 23 - directly attached to the transformer housing 42.
Abstract
Description
Die Erfindung betrifft eine Leuchte entsprechend dem Oberbegriff des Patentanspruchs 1. Derartige Leuchten, in deren Halterung eine Drehverstellvorrichtung eingegliedert ist, sind durch offenkundige Vorbenutzung hinlänglich bekanntgeworden. Eine einfache Art derartiger Drehverstellvorrichtungen kann aus zwei um eine gemeinsame Drehachse gegeneinander verdrehbaren und mittels eines Gewindes gegeneinander preßbaren Halterungsteilen, den beiden Drehverstellteilen, bestehen. Es handelt sich hierbei um Drehverstellvorrichtungen mit ebenen Drehgelenken, welche in der Regel eine Umfangsverstellung von nahezu 360o gestatten. Wenn eine Leuchtenhalterung zwei derartige Drehverstellvorrichtungen mit senkrecht zueinander angeordneten Drehebenen aufweist, kann die von der Leuchtenhalterung getragene Lampenfassungsarmatur raumgelenkig orientiert werden.The invention relates to a luminaire according to the preamble of claim 1. Such luminaires, in the holder of which a rotary adjustment device is incorporated, have become well known through prior public use. A simple type of such rotary adjustment devices can consist of two mounting parts, the two rotary adjustment parts, which can be rotated relative to one another about a common axis of rotation and can be pressed against one another by means of a thread. This is to rotary adjusting devices with flat swivel joints that allow usually a peripheral adjustment of nearly 360 o. If a luminaire holder has two such rotary adjustment devices with mutually perpendicular rotating planes, the lamp holder fitting carried by the luminaire holder can be oriented in a spatially articulated manner.
Leuchten der erfindungsgemäßen Gattung können mit ihrer Halterung beispielsweise an Stromschienen-Adaptern, an Punktauslässen oder an Tragkonstruktionen, wie z.B. an Raumfachwerkteilen, befestigt sein.Luminaires of the genus according to the invention can, for example, be mounted on busbar adapters, at point outlets or on supporting structures, such as be attached to truss parts.
Leuchten stellen inzwischen technisch aufwendige, aus verschiedenen gegeneinander austauschbaren Modulen bestehende Leuchtensysteme dar, welche an die Drehverstellvorrichtungen der Leuchtenhalterung besonders hohe Ansprüche mechanischer Festigkeit stellen, welche die bislang üblichen Drehverstellvorrichtungen zumeist nicht erfüllen können.Luminaires meanwhile represent technically complex luminaire systems consisting of various interchangeable modules, which place particularly high demands on the mechanical stability of the luminaire bracket, which means that hitherto usual rotary adjustment devices mostly can not meet.
Ausgehend von der eingangs beschriebenen, durch offenkundige Vorbenutzung bekanntgewordenen Leuchte, liegt der Erfindung die Aufgabe zugrunde, deren Halterung, insbesondere deren Drehverstellvorrichtung, so zu verbessern, daß diese große Lastmomente schwerer Leuchtensysteme unter genauer Einhaltung der gewählten VerStellposition sicher aufnehmen können.Based on the lamp described at the outset, which has become known through prior public use, the object of the invention is to improve its mounting, in particular its rotary adjustment device, in such a way that it can safely accommodate large load torques of heavy lighting systems with exact adherence to the selected adjustment position.
Diese Aufgabe wird entsprechend der Erfindung dadurch gelöst, daß ein Drehverstellteil ein mittels mindestens eines Distanzstückes von der Drehachse entfernt gehaltenes, etwa streifenförmiges Kreisbahnelement mit Kraft- oder Formschlußmitteln bildet, die mit Kraft- oder Formschlußmitteln des anderen Drehverstellteils zusammenwirken.This object is achieved in accordance with the invention in that a rotary adjustment part forms an approximately strip-shaped circular path element with force or form-locking means, which cooperate with force or form-lock means of the other rotary adjustment part, which is held away from the axis of rotation by means of at least one spacer.
Entsprechend der Erfindung wird ein streifenförmiges Kreisbahnelement mittels mindestens eines Distanzstückes so weit von der Drehachse weg nach außen gehalten und dabei ein so großer Hebelarm gebildet, der es ermöglicht, große Lastmomente asymmetrisch aufgebauter Leuchtensysteme sicher abzufangen. Hierbei ist das mit den Kraft- oder Formschlußmitteln des streifenförmigen Kreisbahnelements Zusammenwirkende Kraft- oder Formschlußmittel des anderen Drehverstellteils in gleichem Maße von der Drehachse weg nach außen versetzt.According to the invention, a strip-shaped circular path element is held so far away from the axis of rotation by means of at least one spacer and thereby a lever arm is formed which enables large load moments of asymmetrically structured lighting systems to be safely intercepted. Here, the force or positive locking means of the other rotary adjustment part, which interacts with the force or positive locking means of the strip-shaped circular path element, is offset to the same extent away from the axis of rotation.
Die erfindungsgemäßen Kreisbahnelemente können sich - je nach Anwendungsfall - entweder über den gesamten Kreisumfang, also den Vollkreis, oder nur über einen Teilumfang, d.h. über einen Teilkreis, erstrecken.The circular path elements according to the invention can - depending on the application - either over the entire Circumference, ie the full circle, or only extend over a partial circumference, ie over a partial circle.
In weiterer Ausgestaltung der Erfindung kann das Kreisbahnelement eine ebene Kreisbahn dadurch aufweisen, daß das Kreisbahnelement zumindest Teil einer Kreisringscheibe mit mindestens einer die Kraft- oder Formschlußmittel tragenden Kreisringfläche ist.In a further embodiment of the invention, the circular path element can have a flat circular path in that the circular path element is at least part of a circular ring disk with at least one circular ring surface carrying the force or form-locking means.
Andererseits sieht die Erfindung vor, daß das Kreisbahnelement kreisförmig gewölbt ist, indem dieses zumindest Teil eines hohlen Kreiszylinders mit mindestens einer die Kraft- oder Formschlußmittel tragenden Zylindermantelfläche ist.On the other hand, the invention provides that the circular path element is curved in a circular manner in that it is at least part of a hollow circular cylinder with at least one cylinder jacket surface that carries the force or form-locking means.
Entsprechend der Erfindung können die Formschlußmittel so gestaltet sein, daß das Kreisbahnelement eine Verzahnung aufweist, in welche mindestens ein Gegenzahn des anderen Drehverstellteils dreharretierend eingreifen kann. Zu dieser erfindungsgemäßen Lösung kann auch eine Ausführungsform gehören, bei welcher der jeweilige Gegenzahn Teil eines sich auf der Verzahnung des Kreisbahnelementes abwälzenden Verstellzahnritzels ist. Dieses Verstellzahnritzel ist zweckmäßig, bedingt durch die Zahngeometrie, selbsthemmend ausgebildet. Vorteilhaft ist es jedenfalls, wenn das Kreisbahnelement auf seiner gesamten Umfangslänge eine Verzahnung aufweist.According to the invention, the positive locking means can be designed so that the circular path element has a toothing in which at least one counter tooth of the other rotary adjustment part can engage in a rotationally locking manner. This solution according to the invention can also include an embodiment in which the respective opposing tooth is part of an adjusting pinion that rolls on the toothing of the circular path element. This adjustable toothed pinion is expediently designed to be self-locking due to the tooth geometry. In any case, it is advantageous if the circular path element has teeth over its entire circumferential length.
In zusätzlicher vorteilhafter Ausgestaltung der Erfindung bildet das Kreisbahnelement, vorzugsweise auf seiner gesamten Umfangslänge, eine Bremsfläche, gegen welche mindestens ein Gegenbremselement des anderen Drehverstellteils dreharretierend anpreßbar ist. Bei jener Ausführungsform könnte das Gegenbremselement etwa zangenförmig am Kreisbahnelement verklemmbar sein.In an additional advantageous embodiment of the invention, the circular path element forms a braking surface, preferably over its entire circumferential length which at least one counter-braking element of the other rotary adjustment part can be pressed in a rotationally locking manner. In that embodiment, the counter-braking element could be clamped to the circular path element approximately in the form of pliers.
Die Gestaltung des Distanzstückes kann etwa speichen- oder Scheibenradartig sein. Dabei kann sich das Distanzstück je nach Anwendungsfall mit seiner Speichen- oder Scheibenradartigen Gestaltung entweder über einen Vollkreis oder nur über einen Kreissektor hinweg erstrecken. Für den Fall eines Kreissektors hätte das Kreisbahnelement eine segmentbogenartige Form.The design of the spacer can be about a spoke or a disc wheel. Depending on the application, the spacer with its spoke or disc wheel-like design can either extend over a full circle or only over a circular sector. In the case of a circular sector, the circular path element would have a segment-like shape.
Auch ist es in weiterer Ausgestaltung der Erfindung möglich, daß das Distanzstück von einem zugleich die Drehachse definierenden Leuchtengehäuseteil, z.B. von einem Transformatorgehäuse, gebildet ist.In a further embodiment of the invention, it is also possible for the spacer to be detached from a lamp housing part that also defines the axis of rotation, e.g. is formed by a transformer housing.
Die erfindungsgemäße Leuchte ist besonders dazu geeignet, leicht und genau reproduzierbar eingestellt zu werden. Hierzu trägt das Kreisbahnelement erfindungsgemäß eine Skala, während das andere Drehverstellteil einen mit der Skala kooperierenden Zeiger bildet.The lamp according to the invention is particularly suitable for being easily and precisely reproducibly adjusted. For this purpose, the circular path element carries a scale according to the invention, while the other rotary adjustment part forms a pointer which cooperates with the scale.

In den Zeichnungen ist jede Leuchte - unabhängig von der jeweiligen Ausführungsform - insgesamt mit der Bezugsziffer 10 versehen.In the drawings, each luminaire - regardless of the specific embodiment - is provided with the
Zwischen ihrem Einspeisungsteil, einem Stromschienenadapter 11, und ihrer Lampenfassungsarmatur 12 zur Aufnahme einer nicht dargestellten Lampe, beispielsweise einer Preßkolbenlampe, befindet sich die Leuchtenhalterung 13.The
In die Halterung 13 eingegliedert sind zwei Drehverstellvorrichtungen A und B.Two rotary adjustment devices A and B are incorporated into the
Wie im Zusammenhang der Fig. 1-3 zu erkennen, ist der Drehverstellvorrichtung A die Drehachse y und der Drehverstellvorrichtung B die Drehachse x zugeordnet.As can be seen in the context of FIGS. 1-3, the rotation adjustment device A is assigned the rotation axis y and the rotation adjustment device B the rotation axis x.
Mit dem Adapter 11 drehfest verbunden ist ein Drehteller 14 über sein nabenförmiges Mittelteil 15. Vom nabenförmigen Mittelteil 15 gehen radial nach außen einstückig angeformte Speichen 16 aus, welche in eine verhältnismäßig hohe Kreisringscheibe 17 übergehen, die eine relativ geringe radiale Erstreckung aufweist.A
Unterseitig stellt die Kreisscheibe 17 eine Kreisringfläche 18 dar, welche eine Verzahnung 19 trägt, deren Zahnflanken sich im wesentlichen radial zur Drehachse y erstrecken.On the underside, the
Unter Zwischenschaltung einer Unterlegscheibe 20 und einer Tellerfeder 21 verbindet ein hohlnietartiges Bauteil 22 das raumfeste nabenförmige Mittelteil 15 und ein nabenförmiges Mittelteil 23 eines Halterungsarmes 24 nach Art eines ebenen Gelenks drehbeweglich miteinander. An sich bekannte Drehbegrenzungsmittel 25 sorgen dafür, daß ein Drehwinkel von 360o in bezug auf die Drehachse y nicht überschritten werden kann.With the interposition of a
Die Kreisringfläche 18 mit ihrer Verzahnung 19 stellt ein streifenförmiges Kreisbahnelement dar, welches durch Distanzstücke, und zwar durch die Speichen 16, weit von der Drehachse y entfernt gehalten ist. Die Kreisringfläche 18 ist mit ihrer Verzahnung 19 am Adapter 11 raumfest gehalten.The
In die Verzahnung 19 der Kreisringfläche 18 greift ein Zahnritzel 30 ein, welches durch den Bund 26 eines am anderen Ende mit einem Gewinde 27 versehenen Lagerbolzens 28 gegen Axialverschiebung gesichert ist. Der Lagerbolzen 28 ist mittels einer Abflachung 29 im mittleren Bolzen-Schaftbereich in Verbindung mit einer entsprechenden Gegenfläche innerhalb der Durchgangsbohrung 31 der Lagerkonsole 32 des Halterungsarms 24 gegen Drehung gesichert.A
Auf diese Weise kann das mit der Verzahnung 19 kämmende Zahnritzel 30 durch Anziehen der Rändelmutter 33 mit einer radialen Klemmfläche 34 gegen eine radiale Gegenfläche 35 der Konsole 32 gepreßt und so an einer Drehung gehindert werden. In diesem Fall ist der Halterungsarm 24 über einen sehr großen Hebelarm hinsichtlich seiner Drehung um die Drehachse y blockiert.In this way, the
Die Drehverstellvorrichtung B funktioniert in grundsätzlich ähnlicher Weise wie die Drehverstellvorrichtung A. Ein Unterschied besteht darin, daß das Kreisbahnelement 36 die Innenmantelfläche eines hohlen Kreiszylinders darstellt. Analog zur Drehverstellvorrichtung A ist auch auf der Zylinderinnenmantelfläche 36 eine Verzahnung 19 vorgesehen, deren Zahnflanken sich zweckmäßig parallel zur Drehachse x erstrecken. Auch die Anordnung des Ritzels 30 mit dem Lagerbolzen 28 ist hinsichtlich Funktion und Gestaltung grundsätzlich ähnlich wie bei der Drehverstellvorrichtung B. Nur weist der Lagerbolzen 28 zu seiner Drehsicherung innerhalb der Lagerkonsole 32 keine Abflachung, sondern einen ihn in einer Radialbohrung 37 durchsetzenden Drehsicherungssplint 38 auf. Der Drehsicherungssplint 38 ist in einem Aufnahmeraum 39 der Konsole 32 lagegesichert.The rotary adjustment device B functions in a fundamentally similar manner to the rotary adjustment device A. A difference is that the
Analog zur Drehverstellvorrichtung A funktioniert die Drehverstellvorrichtung B wie folgt:Analogous to the rotary adjustment device A, the rotary adjustment device B functions as follows:
Durch Anziehen der Rändelmutter 33, und mithin Festlegen des Zahnritzels 30, erfolgt eine Blockierung des Halterungsarms 40 hinsichtlich seiner Drehung um die Drehachse x.By tightening the
In den Fig. 1, 5 und 6 sind noch Skalenteile S benachbart den Kreisbahnelementen 18 und 36 der Drehverstellvorrichtungen A und B angedeutet, die jeweils mit einem zeigerartigen Fortsatz 41 der betreffenden Lagerkonsole 32 kooperieren. Auf diese Weise ist eine bestimmte Einstellage der Anordnung leicht zu reproduzieren.1, 5 and 6, scale parts S are also indicated adjacent to the
Die Verstellvorrichtungen A und B der Ausführungsform gemäß den Fig. 5 und 6 unterscheiden sich grundsätzlich nicht von der Ausführungsform gemäß den Fig. 1-4. Der einzige Unterschied besteht darin, daß bei der Drehverstellvorrichtung B der Fig. 1-4 Speichen 16 die Distanzstücke zwischen der Drehachse x und dem Kreisbahnelement 36 bilden. Bei der Ausführungsform gemäß den Fig. 5 und 6 hingegen stellt ein Transformatorgehäuse 42 gewissermaßen das Distanzstück dar, welches den Segmentbogen 43 von der Drehachse x distanziert. Das Transformatorgehäuse 42 definiert außerdem die Drehachse x mittels eines Drehlageransatzes 44.The adjustment devices A and B of the embodiment according to FIGS. 5 and 6 do not fundamentally differ from the embodiment according to FIGS. 1-4. The only difference is that in the rotary adjustment device B of FIGS. 1-4
Bei den Ausführungsformen gemäß den Fig. 5 und 6 übernimmt das Transformatorgehäuse 42 teilweise die Funktion der Leuchtenhalterung. Und zwar ersetzt das Transformatorgehäuse 42 den Halterungsarm 24 gemäß dem Ausführungsbeispiel der Fig. 1-3. Die dem Drehteller 14 zugeordnete Konsole 32 (s. Fig. 5) zur Halterung des Zahnritzels 30 ist daher - ebenso wie das nabenförmige Mittelteil 23 - unmittelbar am Transformatorgehäuse 42 befestigt.In the embodiments according to FIGS. 5 and 6, the
