At its lower, in the direction of the vertical axis Z of the housing 20 facing region of the adapter 21 terminates with a housing-side adapter side 35, which may also be referred to as an adapter plate 35.
- the adapter plate 35 is connected in the direction of the vertical axis Z with a stop element 33, which is mitbeweglich with the adapter 21. This stop element 33 can therefore also be referred to as a movable stop element 33.
- a further stop member 31 is arranged, which is fixedly connected to the housing 20 and therefore can also be referred to as a fixed stop member 31.
- the rigid connection between the adapter plate 35 and the movable stop member 33 is for this purpose passed through an opening of the fixed stop member 31.
- the spring element 30 is arranged as a conical pressure spring 30, so that a relative movement of the two stop elements 31, 33 along the vertical axis Z against the spring force of the conical compression spring 30 can take place.
- the fixed stop element 31 has a rotation limiting element 32 in the form of a bolt 32 and the movable stop element 33 a Drehbegrenzungselement 34a, 34b in the form of two stages 34a, 34b, which are offset in the circumferential direction of the movable stop member 33 approximately 180 ° to each other.

- the movable stopper member 33 is spaced at a maximum to the fixed stopper member 31.
- the conical compression spring 30 is largely relieved in this state and exerts only so much spring force on the movable stop member 33, that the adapter 21 can be securely held in the housing 20.
- the adapter 21 is completely pulled out of the housing 20 by a user in the direction of the vertical axis Z, wherein the housing 20 must also be held for this purpose.
- the lamp 2 can be kept comfortable this, ie before the user stretch the lamp 2 to the rail bracket 1 on the ceiling and this may need to use a ladder.
- the adapter plate 35 is outside of the adapter-side housing side 29 and the conical compression spring 30 is maximally compressed, so that this movement must be made by the user against the spring force of the conical compression spring 30.
- a third assembly step according to the Fig. 7a, 7b the adapter 21 is rotated by the user about the vertical axis Z by about 90 ° and deposited in this state on the housing 20, so that the adapter plate 35 comes to rest on the adapter side housing side 29.
- the user only has to give way, since the conical compression spring 30 pulls the adapter 21 with its spring force to the housing 20 anyway. Then, the user can let go of the adapter 21 because it is held by the spring force of the conical compression spring 30 in the pulled-out state.
- the adapter 21 can be inserted into the receiving opening 13 of the rail bracket 1 in the direction of the vertical axis Z.
- the user must run the lamp 2 only with one hand, which is very advantageous especially for ceiling mounting and using a ladder.

After insertion into the receiving opening 13 of the adapter 21 is to be introduced by rotation about the vertical axis Z with its Adapternasen 23 and electrical contact elements 22 in the Adapternasenamfactn 14 and electrical insulation 11, which corresponds to the second rotational position.
- a fifth assembly step according to Fig. 9 the user can continue the rotational movement about the vertical axis Z beyond the second rotational position of the adapter 21, so that the adapter plate 35 and the adapter-side housing side 29 can slide on each other until the position of the second assembly step Fig. 6a, 6b is reached again.
- the user can then yield to the spring force of the conical compression spring 30 or release the housing 20 so that the housing 20 is automatically pulled by the spring force of the conical compression spring 30 over the lower part of the adapter 21, cf. Fig. 10 ,
- the housing lugs 24 engage in this case in the receiving opening 13 and thus secure the adapter 21 in the second rotational position.
- the corners 36 of the housing lugs 24 are rounded off in the direction of the transverse axis Y in order to facilitate insertion into the receiving opening 13 and to enable engagement even with a slight rotation of adapter 21 and housing 20 relative to one another.
- the housing 20 with the housing lugs 24 can in turn be secured by the spring force of the conical compression spring 30 in this state.
- the mounting steps four to six which must be done with a ceiling mounting over the head of the user and possibly on a ladder, be performed by the user with one hand, which makes the installation of the lamp 2 according to the invention much easier, faster and more convenient than previously known.
- the Fig. 11 to 13 show a function of a rotation limitation of the lamp 2 according to the invention in detail.
- the Fig. 11 equals to Fig. 5b of the first assembly step.
- the bolt 32 and the steps 34a, 34b are spaced apart in the direction of the vertical axis Z, wherein the bolt 32 in the circumferential direction of the movable stop member 33 to the first stage 34a a minimum distance of about 0 ° and to the second stage 34b a maximum distance of about 180 °.
- the bolt 32 and the steps 34a, 34b are in the plane of the longitudinal axis X and transverse axis Y, but without touching, see Fig. 12 , However, the distance between bolt 32 and first stage 34a is so small that a rotation of the adapter 21 about the vertical axis Z can be prevented in this direction of rotation.
- the movable stop member 33 has a stepless surface which extends through 180 ° to the second stage 34b.
- the adapter 21 is rotated by 90 ° in the direction which is not blocked by the bolt 32 and the first step 34s, the bolt 32 is equidistant from both stages 34a, 34b of the movable stop element 33 by approximately 90 °, see. Fig. 13 ,
- the user can rotate the housing 20 around the vertical axis Z in either of the two directions of rotation to perform the mounting steps four through six.
- This rotational movement is blocked in each case by the contact of the bolt 32 with one of the stages 34a, 34b, so that then the relative positioning of the housing 20 to the adapter 21 according to the sixth assembly step, see. Fig. 10 , is taken.
- the assumption of the position for the sixth assembly step can be facilitated, but it can also be an inadmissible twisting of the electrical lines 28 can be prevented.

Hierbei wird nicht die gesamte Leuchte am Stück an z.B. der Wand montiert, sondern es wird eine Halterung fest an der Wand, der Decke etc. befestigt, auf, in bzw. an der dann eine Leuchte oder mehrere Leuchten montiert werden kann bzw. können. Die Leuchte kann bzw. die Leuchten können in der Halterung nur an genau einer Stelle befestigbar sein oder es können z.B. bei Seilsystemen oder Schienensystemen eine Leuchte oder mehrere Leuchte zumindest entlang einer Längsachse der Halterung variabel befestigbar sein. Auch können die Leuchte bzw. die Leuchten auf, in bzw. an der Halterung verschoben werden können.In the field of luminaires, various systems are known for mounting one or more luminaires, each with a luminous means or with a plurality of luminous means in each case, in or on a support to e.g. a wall, a ceiling, a piece of furniture or the like to fix. In this case, not the entire luminaire is connected in one piece to e.g. mounted on the wall, but it is a bracket firmly attached to the wall, the ceiling, etc., on, in or on the then one or more lights can be mounted or can. The luminaire or the luminaires can be fastened in the holder only in exactly one place or it can be e.g. in cable systems or rail systems, a luminaire or a plurality of luminaires can be fastened variably at least along a longitudinal axis of the mounting. Also, the lamp or the lights can be moved to, in or on the holder.
Derartige Halterungen in Form von Schienenhalterungen weisen hierzu üblicherweise einen entlang der Längsachse langen und starren Körper als Schiene auf, der z.B. mittels Schrauben in Bohrungen der Wand, Decke etc. fest befestigt werden kann. Auf bzw. in die Schiene kann die Leuchte bzw. können die Leuchten auf- bzw. eingesetzt und auf diese Weise gehalten werden. Dies kann über einen Adapter geschehen, der auf der einen Seite mit der Leuchte verbunden und an der anderen Seite zur Befestigung auf bzw. in der Schiene ausgebildet sein kann. Der Adapter kann ausgebildet sein, in einer ersten Drehstellung um die Hochachse in einer Richtung der Hochachse in die Schiene eingesetzt und durch eine Drehung um die Hochachse in eine zweite Drehstellung in der Schiene in der entgegengesetzten Richtung der Hochachse gehalten zu werden, z.B. durch einen Eingriff im Inneren der Schiene, der durch die Drehung bewirkt werden kann.Such brackets in the form of rail brackets for this purpose usually have a long along the longitudinal axis and rigid body as a rail, which can be firmly fixed, for example by means of screws in holes in the wall, ceiling, etc. On or in the rail, the lamp or the lights can be opened or used and held in this way. This can be done via an adapter which is connected on one side with the lamp and formed on the other side for attachment to or in the rail can be. The adapter may be configured to be inserted in a first rotational position about the vertical axis in a direction of the vertical axis in the rail and to be held by a rotation about the vertical axis in a second rotational position in the rail in the opposite direction of the vertical axis, for example by an engagement inside the rail, which can be caused by the rotation.
Um die Leuchte bzw. deren Adapter in der Schiene in diesem gehaltenen Zustand zu sichern, kann z.B. die Drehung um die Hochachse zurück in die erste Drehstellung verhindert werden. Hierzu ist es beispielsweise bekannt, ein Gehäuse bzw. eine Kappe an der Leuchte vorzusehen, welche zum einen den leuchtenseitigen Teil des Adapters, welcher im gehaltenen Zustand sichtbar sein kann, für den Betrachter verdecken und zum anderen eine Sicherung des Adapters in der zweiten Drehstellung bewirken kann. Beispielsweise kann das Gehäuse hierzu an jeder Seite in Richtung der Längsachse zur Schiene hin ein Befestigungsmittel in Form einer Gehäusenase aufweisen, welche derart in die Schiene hineinragen können, so dass die Gehäusenasen beidseitig seitlich in Richtung der Querachse von der Schiene umgriffen werden können. Werden in diesem Zustand der Adapter und das Gehäuse samt Gehäusenasen miteinander fest verbunden, so können die in die Schiene eingreifenden Gehäusenasen eine Drehung des Adapters um die Hochachse verhindern und hierdurch den Adapter in der zweiten Drehstellung sichern.In order to secure the lamp or its adapter in the rail in this held state, e.g. the rotation about the vertical axis back to the first rotational position can be prevented. For this purpose, it is known, for example, to provide a housing or a cap on the lamp, which on the one hand the light-side part of the adapter, which may be visible in the held state, obscure the viewer and on the other effect securing the adapter in the second rotational position can. For example, the housing for this purpose on each side in the direction of the longitudinal axis to the rail have a fastening means in the form of a housing nose, which can protrude into the rail so that the housing lugs can be laterally encompassed on both sides laterally in the direction of the transverse axis of the rail. If, in this state, the adapter and the housing together with the housing lugs are firmly connected to one another, then the housing lugs engaging in the rail can prevent a rotation of the adapter about the vertical axis and thereby secure the adapter in the second rotational position.
Um diese Art der Sicherung herzustellen ist es bisher bekannt, dass das Gehäuse an der Leuchte z.B. um eine Leuchtenverlängerung herum zwischen Adapter und Leuchtmittel angeordnet und sowohl in Richtung der Hochachse als auch um die Hochachse verdrehbar ist. Wurde der Adapter in die zweite Drehstellung in den gehaltenen Zustand gebracht, so kann das Gehäuse derart zur Hochachse gedreht und in Richtung der Hochachse über den Adapter geschoben werden, dass die Gehäusenasen in die Schiene eingreifen.In order to produce this type of fuse, it has heretofore been known that the housing may be attached to the luminaire, e.g. arranged around a lamp extension between the adapter and the bulb and is rotatable both in the direction of the vertical axis and about the vertical axis. If the adapter has been brought into the second rotational position in the held state, then the housing can be rotated in such a way to the vertical axis and pushed in the direction of the vertical axis on the adapter that the housing lugs engage in the rail.
Die Befestigung des Gehäuses samt Gehäusenasen in dieser Stellung erfolgt üblicherweise durch eine Mutter mit Innengewinde, welche um die Leuchtenverlängerung herum zwischen Leuchtmittel und Gehäuse angeordnet ist. Die Leuchtenverlängerung weist hierzu ein Außengewinde in dem Bereich auf, in dem die Mutter zur Befestigung des Gehäuses angeordnet werden soll. Ist somit das Gehäuse zur Sicherung des Adapters in der zweiten Drehstellung positioniert, kann die Mutter in Richtung der Hochachse zum Bereich des Außengewindes hin bewegt und auf das Außengewinde aufgeschraubt werden. Hierdurch kann die Beweglichkeit des Gehäuses in Richtung der Hochachse soweit eingeschränkt werden, dass der Eingriff der Gehäusenasen in die Schiene gesichert werden kann, welcher seinerseits den Eingriff des Adapters in die Schiene in der zweiten Drehstellung sichern kann.The attachment of the housing together with housing lugs in this position is usually carried out by a nut with internal thread, which is arranged around the lamp extension between the bulb and the housing. The lamp extension has for this purpose an external thread in the area in which the nut is to be arranged for attachment of the housing. Is thus the case for securing the adapter in the second Positioned rotary position, the nut can be moved in the direction of the vertical axis to the region of the external thread and screwed onto the external thread. In this way, the mobility of the housing in the direction of the vertical axis can be limited so far that the engagement of the housing lugs can be secured in the rail, which in turn can secure the engagement of the adapter in the rail in the second rotational position.
Nachteilig ist hieran, dass die Montage einer derartigen Leuchte mit Adapter in einer Halterung wie z.B. einer Schienenhalterung umständlich und unbequem sein kann. Denn wird der Adapter in die Schiene gehalten, so ist der Adapter in dieser zweiten Drehstellung durch die Gehäusenasen zu sichern und die Gehäusenasen selbst durch eine weitere Sicherung, nämlich die Mutter, ebenfalls zu sichern. So stellt das Einführen des Adapters in die Schiene und Drehen in die zweite Drehstellung einen ersten Arbeitsgang dar, welcher mit einer Hand ausgeführt werden kann. Der zweite Arbeitsgang erfordert jedoch üblicherweise zwei Hände, weil das Gehäuse in Richtung der Hochachse zur Schiene hin bewegt und dort von Hand gehalten werden muss, während mit der anderen Hand das Schrauben der Mutter auf das Außengewinde der Leuchtenverlängerung erfolgen kann. Dies kann gerade bei einer Deckenmontage über Kopf und auf einer Leiter für einen Benutzer sehr umständlich und unbequem sein.The disadvantage of this is that the mounting of such a lamp with adapter in a holder such. a rail bracket can be cumbersome and uncomfortable. Because the adapter is held in the rail, so the adapter is to be secured in this second rotational position by the housing lugs and the housing lugs themselves by another backup, namely the mother, also secure. Thus, the insertion of the adapter into the rail and turning into the second rotational position represents a first operation, which can be carried out with one hand. However, the second operation usually requires two hands, because the housing moves in the direction of the vertical axis to the rail and there must be held by hand, while with the other hand, the nuts can be screwed onto the external thread of the lamp extension. This can be very cumbersome and uncomfortable for a user, especially when overhead and on a ladder ceiling.

Eine Aufgabe der vorliegenden Erfindung ist es daher, eine Leuchte zur Befestigung in einer Halterung, insbesondere in einer Schienenhalterung, der eingangs beschriebenen Art bereit zu stellen, welche sich einfacher, schneller und bzw. oder bequemer in einer Halterung, insbesondere in einer Schienenhalterung, montieren lässt als bisher bekannt. Insbesondere soll die Montage, insbesondere an einer Decke, einhändig erfolgen können.An object of the present invention is therefore to provide a luminaire for mounting in a holder, in particular in a rail holder, of the type described above, which are easier, faster and / or more convenient in a holder, in particular in a rail mount mounted leaves as previously known. In particular, the assembly, especially on a ceiling, can be done with one hand.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.The object is achieved by the features of the characterizing part of
Somit betrifft die vorliegende Erfindung eine Leuchte zur Befestigung in einer Halterung, welche fest an einer Wand, einer Decke, einem Möbelstück oder dergleichen befestigt sein kann, z.B. mit Schrauben und Dübeln. Die Halterung kann der Befestigung einer Leuchte oder mehrerer gleicher oder unterschiedlicher Leuchten dienen. Diese Halterung kann insbesondere eine Schienenhalterung sein, d.h. eine sich länglich erstreckende Halterung, in der die Leuchte bzw. mehrere Leuchten befestigt werden kann bzw. können. Die Leuchte bzw. Leuchten können in der Schienenhalterung verschiebbar sein.Thus, the present invention relates to a lamp for mounting in a holder, which can be fixedly attached to a wall, a ceiling, a piece of furniture or the like, for example with screws and dowels. The holder can be used to attach a lamp or several identical or different lights. This bracket can In particular, be a rail bracket, ie an elongated bracket in which the lamp or more lights can be attached or can. The luminaire or luminaires can be displaceable in the rail holder.
Dabei ist unter der Formulierung "in der Halterung" auch zu verstehen, dass die Leuchte an oder auf der Halterung oder auch um die Halterung herum befestigt werden kann. Zur Vereinfachung der Formulierung soll jedoch stets nur der Fall der Befestigung "in der Halterung" verwendet werden, der auch alle sonstigen Varianten der Befestigung einer Leuchte bzgl. einer Halterung, welche ihrerseits zuvor fest an einer Wand etc. befestigt wurde, umfasst. Dies gilt ebenso für den Begriff "Eingriff", der entsprechend auch ein "Umgreifen" etc. umfasst.The term "in the holder" also means that the lamp can be attached to or on the holder or around the holder around. To simplify the formulation, however, only the case of attachment "in the holder" should always be used, which also includes all other variants of attaching a luminaire with respect to a holder, which in turn has been previously firmly attached to a wall, etc. This also applies to the term "intervention", which accordingly also includes a "grasping", etc.
Die Leuchte weist einen Adapter zum Eingriff in die Halterung auf, wobei der Adapter in einer ersten Drehstellung um eine Hochachse in die Halterung eingeführt und in einer zweiten Drehstellung um die Hochachse in der Halterung in einer Richtung der Hochachse gehalten werden kann. Der Adapter kann ein Bestandteil der Leuchte sein, der zu diesem Zweck geeignet ist, wie z.B. ein hervorragendes Element, welches von der Halterung aufgenommen werden und mit dieser eine Verbindung eingehen kann, die vorzugsweise auch wieder zerstörungsfrei lösbar sein kann. Als Hochachse wird die kartesische Achse angesehen, in der die Leuchte mit dem Adapter in die Halterung eingeführt werden muss, um einen Eingriff in die Halterung zu erreichen, wobei das Einführen in der ersten Drehstellung möglich ist. In der zweiten Drehstellung ist der Eingriff erfolgt, so dass ein Herausziehen des Adapters aus der Halterung in der entgegengesetzten Richtung der Hochachse nicht möglich ist. Mit anderen Worten kann der Adapter mittels einer translatorischen und anschließenden rotatorischen Bewegung in der Halterung gehalten werden.The lamp has an adapter for engagement in the holder, wherein the adapter can be inserted in a first rotational position about a vertical axis in the holder and held in a second rotational position about the vertical axis in the holder in a direction of the vertical axis. The adapter may be a component of the luminaire suitable for this purpose, e.g. an excellent element, which can be absorbed by the holder and can make a connection with it, which can preferably also be non-destructively detachable again. The vertical axis is the Cartesian axis, in which the luminaire with the adapter has to be inserted into the holder in order to achieve an engagement in the holder, wherein the insertion in the first rotational position is possible. In the second rotational position of the engagement takes place, so that an extraction of the adapter from the holder in the opposite direction of the vertical axis is not possible. In other words, the adapter can be held in the holder by means of a translatory and subsequent rotational movement.
Die Leuchte weist ferner wenigstens ein Befestigungsmittel zum Eingriff in die Halterung auf, wobei das Befestigungsmittel in der zweiten Drehstellung des Adapters derart in die Halterung eingeführt werden kann, so dass der Adapter in der zweiten Drehstellung gesichert wird. Das Befestigungsmittel kann ein weiterer Bestandteil der Leuchte sein, der diesen Zweck erfüllen kann, wie z.B. ein hervorragendes Element, welches in die Halterung derart eingreifen kann, dass die Drehung des Adapters von der zweiten Drehstellung zurück in die erste Drehstellung verhindert werden kann. Dabei ist das Befestigungsmittel gleichzeitig derart vorzusehen, dass die Drehung des Adapters von der ersten Drehstellung in die zweite Drehstellung ermöglicht werden kann.The lamp further comprises at least one fastening means for engaging in the holder, wherein the fastening means in the second rotational position of the adapter can be inserted into the holder in such a way that the adapter is secured in the second rotational position. The fastener may be another component of the luminaire that can serve this purpose, such as a protruding element which fits into the fixture engage such that the rotation of the adapter can be prevented from the second rotational position back to the first rotational position. In this case, the fastening means is simultaneously provided such that the rotation of the adapter from the first rotational position can be made possible in the second rotational position.
Die erfindungsgemäße Leuchte zeichnet sich durch wenigstens ein Federelement aus, welches derart angeordnet und ausgebildet ist, dass der Eingriff des Befestigungsmittels in die Halterung durch die Federkraft des Federelements gesichert werden kann. Das Federelement kann hierzu eine Zugkraft oder eine Druckkraft ausüben können. Das Federelement kann als eine Metallfeder oder als ein elastischer Körper wie z.B. ein Gummikörper ausgebildet sein. Mittels einer Metallfeder können verschiedene Ausführungsformen von Zug- und Druckfedern einfach realisiert werden. Vorzugsweise kann das Federelement als eine Kegeldruckfeder aus Metall umgesetzt werden, welche einen kompakten Aufbau mit gerichteter Federkraft in eine translatorische Richtung bei gleichzeitiger Möglichkeit zur Verdrehung in einem gewissen Maße ermöglicht.The lamp according to the invention is characterized by at least one spring element, which is arranged and designed such that the engagement of the fastening means in the holder can be secured by the spring force of the spring element. The spring element can exert a tensile force or a compressive force for this purpose. The spring element may be in the form of a metal spring or an elastic body such as a metal spring. be formed a rubber body. By means of a metal spring various embodiments of tension and compression springs can be easily realized. Preferably, the spring element can be implemented as a conical compression spring made of metal, which allows a compact structure with directed spring force in a translational direction with simultaneous possibility for rotation to a certain extent.
Unter einem Eingriff ist dabei zu verstehen, dass ein Element durch ein anderes Element in mindestens einer Richtung einer Achse in der Bewegung blockiert werden kann, d.h. die Ausführung der Bewegung in dieser Richtung verhindert werden kann. In diesem Fall greift der Adapter in die Halterung derart ein, dass eine Bewegung entgegen der Richtung des Einführens nach der Drehbewegung formschlüssig verhindert werden kann. Ferner greift das Befestigungsmittel ebenfalls in die Halterung ein, wobei jedoch erfindungsgemäß dieser Eingriff durch die Federkraft des Federelements bewirkt und bzw. oder gehalten werden kann. Mit anderen Worten kann anstelle der bekannten Schraubverbindung zur Sicherung des Befestigungsmittels im Eingriff mit der Halterung ein Federelement wie vorzugsweise eine mechanische Kegeldruckfeder verwendet werden.By an intervention is meant that one element can be blocked by another element in at least one direction of an axis in the movement, i. the execution of the movement in this direction can be prevented. In this case, the adapter engages in the holder such that a movement counter to the direction of insertion after the rotational movement can be positively prevented. Furthermore, the fastening means also engages in the holder, but according to the invention this engagement can be effected and / or held by the spring force of the spring element. In other words, instead of the known screw connection for securing the fastening means in engagement with the holder, a spring element such as preferably a mechanical conical compression spring can be used.
Dies ist vorteilhaft, weil sich auf diese Art und Weise das Befestigungsmittel in einer Richtung der Hochachse unter Spannung des Federelements, d.h. gegen dessen Federkraft, von dem Adapter wegbewegen lassen kann, um diesem den Eingriff in die Halterung zu ermöglichen. Ist dieser Eingriff erfolgt, kann das Befestigungsmittel durch die Federkraft wieder zurück in seine Ausgangsstellung bei entspanntem bzw. entspannterem Federelement gebracht werden und hierdurch selbst derart in die Halterung eingreifen, dass der Adapter gegen Zurückdrehen in die erste Drehstellung gesichert werden kann. Die Federkraft des Federelements ist dabei derart auszulegen, dass dieser Zweck erfüllt werden kann. Hierdurch kann zur Montage der Leuchte in der Halterung das Federelement gespannt, der Adapter in die Halterung eingeführt und verdreht und dann das Federelement einfach losgelassen werden. Dies kann deutlich einfacher, schneller und bequemer erfolgen als die bisher bekannte Montage mit geschraubter Sicherung des Befestigungsmittels. Mit anderen Worten erfolgt durch das Federelement erfindungsgemäß sozusagen eine selbstständig Sicherung des Befestigungsmittels in der zweiten Drehstellung.This is advantageous because in this way the fastening means in a direction of the vertical axis under tension of the spring element, ie against its spring force, can move away from the adapter to allow this engagement in the holder. If this intervention is carried out, the fastening means by the spring force back to its original position at relaxed or relaxed Be brought spring element and thereby intervene even in such a way in the holder that the adapter can be secured against turning back into the first rotational position. The spring force of the spring element is to be interpreted such that this purpose can be met. In this way, the spring element can be clamped for mounting the lamp in the holder, the adapter inserted into the holder and rotated and then the spring element can be easily released. This can be much easier, faster and more convenient than the previously known assembly with screwed securing the fastener. In other words, by the spring element according to the invention, so to speak, an independent backup of the fastener in the second rotational position.
Vorteilhaft ist hierbei insbesondere, dass keine zusätzlichen Elemente wie die Mutter zusätzlich zur Leuchte selbst bedient werden müssen, was üblicherweise eine zweite Hand erfordern kann. Daher kann diese Montage vorzugsweise einhändig erfolgen.It is advantageous in particular that no additional elements such as the mother in addition to the lamp itself must be operated, which may usually require a second hand. Therefore, this assembly can preferably be done with one hand.
Vorteilhaft ist weiterhin, dass bei ausreichend großer Federkraft des Federelements zur Halterung hin zusätzlich eine kraftschlüssige Befestigung der Leuchte in der Halterung erfolgen kann. Hierdurch kann die Leuchte bei einer vertikalen Montage wie z.B. einer Wandmontage in Position gehalten werden, insbesondere bei einer in vertikaler Richtung orientierten Schienenhalterung.A further advantage is that with sufficiently large spring force of the spring element for holding out additionally a non-positive attachment of the lamp can be done in the holder. This allows the lamp in a vertical mounting such. a wall mounting are held in position, in particular in a vertically oriented rail bracket.
Vorteilhaft ist auch, dass das Befestigungsmittel und das Federelement bei der Montage der Leuchte in der Halterung nicht von außen für den Benutzern zugänglich sein müssen. Hierdurch kann ein flacher Aufbau der Leuchte realisiert werden. Auch müssen Schrauben, Muttern und dergleichen nicht beim Design der Leuchte berücksichtigt werden.It is also advantageous that the fastening means and the spring element during installation of the lamp in the holder need not be accessible to the user from the outside. As a result, a flat structure of the lamp can be realized. Also, screws, nuts and the like must not be considered in the design of the lamp.
Gemäß einem Aspekt der vorliegenden Erfindung sind der Adapter und das Befestigungsmittel relativ zueinander in Richtung der Hochachse beweglich und relativ zueinander um die Hochachse verdrehbar. Hierdurch kann die Beweglichkeit entlang der Hochachse gegeben werden, welche dem Adapter das Einführen in die Halterung ermöglichen kann, ohne hierbei durch das Befestigungsmittel blockiert oder gehindert zu werden. Die Beweglichkeit um die Hochachse ermöglicht die Positionierung des Befestigungsmittels relativ zum im Eingriff befindlichen Adapter, um diesen dort zu sichern.According to one aspect of the present invention, the adapter and the fastening means are movable relative to each other in the direction of the vertical axis and rotatable relative to each other about the vertical axis. In this way, the mobility can be given along the vertical axis, which can allow the adapter to insert into the holder, without being blocked or prevented by the fastener. The mobility about the vertical axis allows positioning of the fastener relative to the engaged adapter to secure it there.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung ist das Federelement zwischen dem Adapter und dem Befestigungsmittel derart angeordnet, dass das Federelement auf den Adapter und das Befestigungselement in Richtung der Hochachse eine aufeinander zu gerichtete Federkraft ausüben kann. Diese Federkraft kann als Zug oder Druck realisiert sein. Hierdurch kann das Federelement bewirken, dass Adapter und Befestigungsmittel bei der Montage unter Spannung des Federelements voneinander weg bewegt werden können, um dem Adapter das Einführen in die Halterung in der ersten Drehstellung zu ermöglichen, jedoch durch die Spannung des Federelements danach streben, wieder in eine enger zueinander angeordnete Stellung zurückzukehren, in der dann die Sicherung des Adapters in der zweiten Drehstellung durch das Befestigungsmittel erfolgen kann. Dabei kann das Federelement seinerseits das Befestigungsmittel durch seine Federkraft im Eingriff in der Halterung sichern.According to a further aspect of the present invention, the spring element between the adapter and the fastening means is arranged such that the spring element on the adapter and the fastening element in the direction of the vertical axis can exert a spring force directed towards each other. This spring force can be realized as a train or pressure. This can cause the spring element that adapter and fastening means can be moved away from each other in the assembly under tension of the spring element to allow the adapter to insert into the holder in the first rotational position, but strive by the tension of the spring element, again in a return closer to each other arranged position in which then the backup of the adapter in the second rotational position can be done by the fastener. In this case, the spring element in turn secure the fastening means by its spring force in engagement in the holder.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung kann das Befestigungsmittel in der ersten Drehstellung des Adapters gegen die Federkraft des Federelements in Richtung der Hochachse derart beabstandet zur Halterung positioniert werden, dass das Befestigungsmittel das Eingreifen des Adapters in die Halterung nicht blockiert, und kann das Befestigungsmittel in der zweiten Drehstellung des Adapters durch die Federkraft des Federelements in Richtung der Hochachse zum Eingriff in die Halterung gebracht werden. Auf diese Weise kann verhindert werden, dass das Einführen des Adapters in die Halterung durch das Befestigungsmittel gestört werden kann, indem das Befestigungsmittel in diesem Montageschritt ausreichend zur Halterung beabstandet ist. Ist der Eingriff des Adapters in die Halterung durch die Drehung in die zweite Drehstellung erfolgt, kann durch die Federkraft selbstständig die Sicherung des Befestigungsmittels in dieser zweiten Drehstellung des Adapters erfolgen.According to a further aspect of the present invention, in the first rotational position of the adapter, the fastening means may be positioned against the spring force of the spring element in the direction of the vertical axis spaced from the holder, such that the fastening means does not block the engagement of the adapter in the holder, and the fastening means in FIG the second rotational position of the adapter are brought by the spring force of the spring element in the direction of the vertical axis for engagement in the holder. In this way, it can be prevented that the insertion of the adapter into the holder can be disturbed by the fastening means by the fastening means in this assembly step is sufficiently spaced from the holder. If the engagement of the adapter in the holder is carried out by the rotation in the second rotational position, can be done by the spring force automatically securing the fastener in this second rotational position of the adapter.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist das Befestigungsmittel in Richtung einer Querachse wenigstens eine abgerundete oder abgeschrägte Ecke oder Kante auf, um bei einer Bewegung in Richtung der Hochachse zur Halterung hin ein Eingreifen zu erleichtern. Die Querachse ist senkrecht zur Hochachse angeordnet und entspricht der Orientierung, in der sich die Halterung bzw. dessen Öffnung erstreckt, in die der Eingriff des Befestigungsmittels erfolgen kann. Dabei ist das Befestigungsmittel je nach Gestaltung der Halterung bzw. der Öffnung derart auszubilden, dass das Eingreifen erleichtert werden kann.According to another aspect of the present invention, the attachment means in the direction of a transverse axis has at least one rounded or chamfered corner or edge to facilitate engagement upon movement in the direction of the vertical axis towards the support. The transverse axis is arranged perpendicular to the vertical axis and corresponds to the orientation in which the holder or its opening extends into which the engagement of the Fastener can be done. In this case, the fastening means, depending on the design of the holder or the opening in such a way that the intervention can be facilitated.
Mit anderen Worten ist das Befestigungsmittel an wenigstens einer Seite, d.h. Ecke bzw. Kante, derart auszubilden, dass es bei einer Bewegung in Richtung der Hochachse auf die Halterung zu einer Positionierung in Richtung der Querachse in einem gewissen Maße selbstständig korrigieren kann. Hierdurch kann das Befestigungsmittel etwas ungenauer zur Halterung bzw. Öffnung positioniert werden, bevor die Bewegung zur Halterung erfolgt. Dies ist insbesondere aufgrund der Verwendung des Federelements vorteilhaft, weil die Federkraft des Federelements diese Bewegung selbstständig ausführt und dann das Befestigungsmittel in einer ungefähren Positionierung zur Halterung losgelassen werden kann, um die genaue Positionierung und Sicherung selbstständig durchzuführen. Dies vereinfacht die Montage noch mehr.In other words, the fastener is on at least one side, i. Corner or edge, in such a way that it can correct itself to a certain extent on a movement in the direction of the vertical axis on the holder to a positioning in the direction of the transverse axis. As a result, the fastener can be positioned somewhat inaccurate to the holder or opening before the movement to the holder. This is particularly advantageous because of the use of the spring element, because the spring force of the spring element performs this movement independently and then the fastener can be released in an approximate positioning for mounting to perform the exact positioning and securing independently. This simplifies the assembly even more.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist die Leuchte ein Gehäuse auf, an dem das Befestigungsmittel fest angeordnet ist und an dem der Adapter in Richtung der Hochachse beweglich und um die Hochachse verdrehbar angeordnet ist. Das Gehäuse und das Befestigungsmittel sind vorzugsweise einteilig, d.h. aus einzelnen Teile und einem Gesamtteil zusammengesetzt, oder einstückig, d.h. aus einem Stück geformt, ausgebildet. Vorzugsweise weist das Gehäuse zwei Befestigungsmittel auf, die vorzugsweise in einer Richtung der Längsachse einander gegenüberliegend an dem Gehäuse angeordnet sind. Vorteilhaft ist hierbei, dass sich eine Leuchte mittels ihres Gehäuses bei der Montage gut handhaben lässt. Auch kann eine Belastung des Leuchtmittels bei der Montage vermieden werden.According to a further aspect of the present invention, the luminaire has a housing, on which the fastening means is fixedly arranged and on which the adapter is arranged to be movable in the direction of the vertical axis and to be rotatable about the vertical axis. The housing and fastener are preferably one-piece, i. composed of individual parts and a total part, or in one piece, i. formed from one piece, formed. Preferably, the housing has two attachment means, which are preferably arranged opposite to one another in a direction of the longitudinal axis on the housing. The advantage here is that a lamp can be handled well by means of their housing during assembly. Also, a burden of the bulb can be avoided during assembly.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung ist der Adapter ausgebildet, in der zweiten Drehstellung und bei gesichertem Befestigungsmittel in der Halterung und bzw. oder im Gehäuse im Wesentlichen aufgenommen werden zu können. Hierdurch kann der Adapter nach der Montage der Leuchte in der Halterung für den Betrachter verborgen bleiben, was den Anblick der Leuchte verbessern kann. Auch kann die Leuchte kompakter ausgebildet werden, weil auf eine Zugänglichkeit zu den Sicherungsmitteln wie bisher Mutter und Gewinde aufgrund des Federelements verzichtet werden kann. Vorzugsweise kann hierzu die für die Beweglichkeit des Adapters in Richtung der Hochachse erforderliche Mechanik sowie das Federelement im Gehäuse vollständig aufgenommen werden, so dass lediglich der Adapter aus dem Gehäuse herausragt und im montierten Zustand im Wesentlichen, vorzugsweise vollständig, in der Halterung aufgenommen sein kann.According to a further aspect of the present invention, the adapter is designed to be substantially received in the second rotational position and with a secured fastening means in the holder and / or in the housing. As a result, the adapter can remain hidden in the holder for the viewer after mounting the lamp, which can improve the appearance of the lamp. Also, the lamp can be made more compact, because it can be dispensed with accessibility to the securing means as previously nut and thread due to the spring element. Preferably For this purpose, the required for the mobility of the adapter in the direction of the vertical axis mechanism and the spring element in the housing can be completely absorbed, so that only the adapter protrudes from the housing and in the assembled state substantially, preferably completely, can be accommodated in the holder.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist das Gehäuse eine adapterseitige Gehäuseseite und der Adapter eine gehäuseseitige Adapterseite auf, wobei der Adapter gegen die Federkraft des Federelements soweit aus dem Gehäuse herausgezogen werden kann, dass die gehäuseseitige Adapterseite zur adapterseitigen Gehäuseseite beabstandet ist und der Adapter gegenüber dem Gehäuse um die Hochachse gedreht werden kann. Auf diese Weise kann realisiert werden, dass der Adapter gegenüber dem Gehäuse bzw. dessen Befestigungsmittel in Richtung der Hochachse entgegen der Federkraft des Federelements beweglich und um die Hochachse verdrehbar ist, ohne hierbei durch das Gehäuse behindert zu werden.According to a further aspect of the present invention, the housing has an adapter-side housing side and the adapter has a housing-side adapter side, wherein the adapter against the spring force of the spring element can be pulled out of the housing against the spring force of the spring element, that the housing-side adapter side to adapter side housing side is spaced and the adapter opposite the housing can be rotated about the vertical axis. In this way it can be realized that the adapter relative to the housing or its fastening means in the direction of the vertical axis against the spring force of the spring element is movable and rotatable about the vertical axis, without being hindered by the housing.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung kann die gehäuseseitige Adapterseite des aus dem Gehäuse herausgezogenen und um die Hochachse gedrehten Adapters mittels der Federkraft des Federelements in Kontakt mit der adapterseitigen Gehäuseseite gehalten werden. Mit anderen Worten kann der um die Hochachse verdrehte Adapter mit seiner gehäuseseitigen Adapterseite auf dem Gehäuse bzw. dessen adapterseitigen Seite abgesetzt und dort durch die Federkraft des Federelements gehalten werden. Dies ist vorteilhaft, weil der Adapter zur Montage in der Halterung aus dem Gehäuse herausgezogen und gedreht auf diesem festgeklemmt werden kann. Da hierzu üblicherweise zwei Hände erforderlich sind, diese Montagestellung der Leuchte dann jedoch selbstständig durch die Federkraft des Federelements beibehalten werden kann, kann dieser Montageschritt jederzeit vor dem Einführen des Adapters in die Halterung erfolgen, z.B. vor dem Besteigen einer Leiter. Dies vereinfacht die Montage weiterhin.According to another aspect of the present invention, the housing-side adapter side of the adapter pulled out of the housing and rotated around the vertical axis can be held in contact with the adapter-side housing side by means of the spring force of the spring element. In other words, the adapter rotated about the vertical axis adapter can be placed with its housing side adapter side on the housing or its adapter side side and held there by the spring force of the spring element. This is advantageous because the adapter for mounting in the holder can be pulled out of the housing and rotated clamped on this. Since this usually two hands are required, but this mounting position of the lamp then can be maintained independently by the spring force of the spring element, this assembly step can be done at any time before inserting the adapter into the holder, e.g. before climbing a ladder. This further simplifies the assembly.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist die Leuchte eine Drehbegrenzung auf, welche die Drehbarkeit des aus dem Gehäuse herausgezogenen Adapters um die Hochachse begrenzen kann. Diese Drehbegrenzung kann durch mechanische Blockade den Drehwinkel um die Hochachse einschränken. Dies kann derart erfolgen, dass ein Verdrehen von elektrischen Leitungen, die über den Adapter mit der Halterung elektrisch leitfähig verbunden werden können, zwischen Gehäuse und Adapter vermieden werden kann.According to a further aspect of the present invention, the luminaire has a rotation limitation, which can limit the rotatability of the adapter pulled out of the housing about the vertical axis. This rotation limit can limit the rotation angle about the vertical axis by mechanical blockade. This can be done like this take place that a twisting of electrical lines that can be electrically conductively connected via the adapter to the holder, between the housing and adapter can be avoided.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung kann die Drehbegrenzung die Drehbarkeit des aus dem Gehäuse herausgezogenen Adapters um die Hochachse in wenigstens eine Drehrichtung auf maximal ca. 180° begrenzen. Somit kann der Adapter auch senkrecht, d.h. um 90°, zum Gehäuse verdreht werden, so dass der Adapter bei der Montage bestmöglich von jenseits des Gehäuses für den Benutzer sichtbar und damit gut in die Halterung einführbar sein kann. Vorteilhaft ist dabei auch, dass die Verdrehung des Adapters aus dieser senkrechten Drehstellung zurück in eine Drehstellung, in der der Adapter in das Gehäuse eingezogen werden, in beide Drehrichtungen um 90° erfolgen kann, so dass der Benutzer die freie Wahl der Drehrichtung hat.According to a further aspect of the present invention, the rotation limiting the rotation of the drawn out of the housing adapter about the vertical axis in at least one direction of rotation to a maximum of about 180 ° limit. Thus, the adapter may also be vertical, i. rotated 90 ° to the housing, so that the adapter during assembly as possible from beyond the housing visible to the user and thus well into the holder can be inserted. It is also advantageous that the rotation of the adapter from this vertical rotational position back into a rotational position in which the adapter are retracted into the housing, can be done in both directions by 90 °, so that the user has the free choice of direction.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist die Drehbegrenzung ein Drehbegrenzungselement auf, das an einem feststehenden Anschlagselement angeordnet ist, und weist ein Drehbegrenzungselement auf, das an einem mit dem Adapter mitbeweglichen Anschlagselement angeordnet ist, wobei sich die beiden Drehbegrenzungselemente im Zustand des aus dem Gehäuse herausgezogenen Adapters in einer Ebene senkrecht zur Hochachse blockieren können. Die Ebene senkrecht zur Hochachse entspricht der Ebene, die durch eine Längsachse und eine Querachse aufgespannt wird. Dabei sind die Drehbegrenzungselemente vorzugsweise derart ausgebildet, dass sie beide Drehrichtungen um die Hochachse blockieren können.According to a further aspect of the present invention, the rotation limiter has a rotation limiting element, which is arranged on a fixed stop element, and has a rotation limiting element, which is arranged on a movable with the adapter stop member, wherein the two rotation limiting elements in the state of the out of the housing pulled adapter in a plane perpendicular to the vertical axis can block. The plane perpendicular to the vertical axis corresponds to the plane defined by a longitudinal axis and a transverse axis. The rotation limiting elements are preferably designed such that they can block both directions of rotation about the vertical axis.
Das feststehende Anschlagselement kann fest mit dem Gehäuse verbunden und innerhalb des Gehäuses angeordnet sein. Der Adapter kann mit dem mitbeweglichen Anschlagselement fest verbunden sein, so dass die Mitbeweglichkeit dieses Anschlagselement sich durch die Beweglichkeit des Adapters gegenüber dem Gehäuse ergeben kann. Zwischen den beiden Anschlagselementen kann das Federelement angeordnet sein, so dass der Adapter, wenn er aus dem Gehäuse herausgezogen wird, das Federelement zusammendrücken und hierdurch spannen kann. Ist der Adapter aus dem Gehäuse herausgezogen, so dass er um die Hochachse gedreht werden kann, so liegen die beiden Drehbegrenzungselemente in einer Ebene und können bei Drehung aneinander stoßen und hierdurch die Drehbewegung um die Hochachse wenigstens in einer Drehrichtung, vorzugsweise in beiden Drehrichtungen, blockieren und begrenzen. Auf diesen Weise kann eine Drehbegrenzung umgesetzt werden, die lediglich im herausgezogenen Zustand des Adapters wirken kann und damit genau dann, wenn es erforderlich ist.The fixed stop member may be fixedly connected to the housing and disposed within the housing. The adapter can be firmly connected to the movable stop element, so that the Mitbeweglichkeit this stop element can result from the mobility of the adapter relative to the housing. Between the two stop elements, the spring element may be arranged, so that the adapter when it is pulled out of the housing, compress the spring element and thereby tension. If the adapter is pulled out of the housing, so that it can be rotated about the vertical axis, so are the two rotation limiting elements in a plane and can abut each other upon rotation and thereby block and limit the rotational movement about the vertical axis at least in one direction of rotation, preferably in both directions of rotation. In this way, a rotation limitation can be implemented, which can act only in the pulled-out state of the adapter and thus, if necessary.
Vorzugsweise kann hierzu die Drehbegrenzung des feststehenden Anschlagselements als Bolzen ausgebildet sein, der in Richtung des mitbeweglichen Anschlagselements zeigt, welches als Scheibe ausgebildet sein kann, an der eine Kegeldruckfeder als Federelement anliegen kann. Die Scheibe kann in Umfangsrichtung eine Erhebung wie z.B. einen Rand aufweisen, der in Richtung des feststehenden Anschlagselements zeigt. Die Drehbegrenzung der Scheibe kann dann durch jeweils eine Stufe des Rands ausgebildet sein, so dass der Bolzen und der Rand in einer Ebene liegen und sich gegenseitig in beiden Drehrichtungen blockieren können, falls der Adapter aus dem Gehäuse herausgezogen ist.Preferably, for this purpose, the rotational limit of the fixed stop member may be formed as a bolt, which points in the direction of the movable stop member, which may be formed as a disc on which a conical compression spring may abut as spring element. The disk may have a protrusion in the circumferential direction, e.g. have an edge pointing in the direction of the fixed stop member. The rotation limit of the disc can then be formed by a respective step of the edge, so that the bolt and the edge lie in one plane and can block each other in both directions of rotation, if the adapter is pulled out of the housing.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist der Adapter in einer Ebene senkrecht zur Hochachse eine Kontur auf, so dass der Adapter in der ersten Drehstellung um die Hochachse in die Halterung eingeführt und in der zweiten Drehstellung um die Hochachse in der Halterung in Richtung der Hochachse gehalten werden kann. Diese Kontur kann vorzugsweise als Raute ausgebildet sein, dessen Fläche in der Ebene der Längsachse und Querachse liegt. Zur Kontur können auch Elemente wie z.B. seitliche Vorsprünge gehören, die mit dem Adapter verbunden oder mit dem Adapter einteilig oder einstückig ausgebildet sind. Auf diese Weise kann das seitliche Maß des Adapters durch eine Drehung um die Hochachse verändert werden, so dass der Adapter in der ersten Drehstellung in die Halterung eingeführt und durch Drehung in die zweite Drehstellung dort formschlüssig entgegen der Einführrichtung gehalten werden kann.According to a further aspect of the present invention, the adapter has a contour in a plane perpendicular to the vertical axis, so that the adapter is inserted in the first rotational position about the vertical axis in the holder and in the second rotational position about the vertical axis in the holder in the direction of the vertical axis can be held. This contour may preferably be formed as a rhombus whose surface lies in the plane of the longitudinal axis and transverse axis. The contour may also contain elements such as e.g. include lateral projections which are connected to the adapter or formed integrally with the adapter or in one piece. In this way, the lateral extent of the adapter can be changed by a rotation about the vertical axis, so that the adapter can be inserted into the holder in the first rotational position and held there by rotation in the second rotational position there positively against the insertion direction.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist der Adapter wenigstens zwei seitliche Vorsprünge in einer Richtung einer Querachse auf, die ausgebildet sind, in der zweiten Drehstellung in zwei korrespondierende Vorsprungaufnahmen der Halterung in der Richtung der Querachse eingreifen zu können, so dass der Adapter durch die Vorsprünge in Richtung der Hochachse in den Vorsprungaufnahmen gehalten werden kann. Diese Vorsprungaufnahmen können als seitliche Öffnungen ausgebildet sein, die wenigstens den Adapter entgegen der Einführrichtung blockieren können und vorzugsweise gleichzeitig die Drehung um die Hochachse derart begrenzen, dass die zweite Drehstellung die Grenze dieser Drehbewegung in dieser Drehrichtung darstellt. In den Vorsprungaufnahmen kann der Adapter mit seinen Vorsprüngen zusätzlich auch kraftschlüssig gehalten werden, indem die Vorsprünge und Vorsprungsaufnahmen korrespondierend geformt und ggfs. zumindest teilweise eine spannende bzw. klemmende Federkraft aufeinander ausüben können.According to a further aspect of the present invention, the adapter has at least two lateral projections in a direction of a transverse axis, which are adapted to be able to engage in the second rotational position in two corresponding projection receptacles of the holder in the direction of the transverse axis, so that the adapter Projections can be held in the direction of the vertical axis in the projection receptacles. These Projection receptacles may be formed as lateral openings, which can block at least the adapter against the insertion direction and preferably at the same time limit the rotation about the vertical axis such that the second rotational position represents the limit of this rotational movement in this direction of rotation. In the protruding receptacles, the adapter with its projections can also be held in a non-positive manner by the projections and projections receptacles formed corresponding and possibly. At least partially an exciting or clamping spring force can exert on each other.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung weist der Adapter wenigstens zwei elektrische Kontaktelemente auf, welche in der zweiten Drehstellung einen elektrisch leitfähigen Kontakt mit zwei elektrischen Leitern der Halterung aufweisen können. Diese Kontaktelemente sind vorzugsweise als seitliche Vorsprünge in Richtung der Querachse ausgebildet. Die elektrischen Leiter der Halterung sind vorzugsweise von Isolationsmitteln umgeben und in diese zurückversetzt angeordnet, um einen elektrischen Kontakt mit einem Benutzer z.B. bei der Montage zu vermeiden. Hierdurch kann eine elektrische Versorgung der Leuchte über den Adapter realisiert werden, so dass keine separaten Leitungen und Montageschritte für einen elektrischen Anschluss der Leuchte erforderlich sind.According to a further aspect of the present invention, the adapter has at least two electrical contact elements, which in the second rotational position can have an electrically conductive contact with two electrical conductors of the holder. These contact elements are preferably formed as lateral projections in the direction of the transverse axis. The electrical conductors of the support are preferably surrounded by and recessed into insulating means to make electrical contact with a user e.g. to avoid during assembly. In this way, an electrical supply of the lamp can be realized via the adapter, so that no separate lines and assembly steps for an electrical connection of the lamp are required.

Die
Die Halterung 1 ist als Schienenhalterung 1 ausgebildet. Die Schienenhalterung 1 weist eine Halterungsaufnahme 10 in Form einer Schiene 10 auf. Die Schiene 10 ist U-förmig ausgebildet, so dass sich eine Aufnahmeöffnung 13 oder ein Aufnahmeschlitz 13 bildet. Innerhalb der Aufnahmeöffnung 13 sind in den seitlichen Flanken der Schiene 10 zwei elektrische Leiter 12 angeordnet, die sich in der Längsachse X erstrecken und sich in der Querachse Y direkt gegenüberliegen. Die elektrischen Leiter 12 sind jeweils von einer elektrischen Isolation 11 U-förmig derart umschlossen, dass die elektrischen Isolationen 11 zueinander hin offen ausgebildet sind. Parallel zu den elektrischen Leitern 12 sind in der Schiene 10 zwei Vorsprungaufnahmen 14 angeordnet, die auch als Adapternasenaufnahmen 14 bezeichnet werden können und die ebenfalls U-förmig geformt sind, so dass die Öffnungen in der Querachse Y zueinander hin ausgerichtet sind. Die Schiene 10 ist an z.B. einer Decke fest befestigt, so dass die Aufnahmeöffnung 13 von der Decke weg nach unten in den Raum geöffnet ist.The
Die Leuchte 2 weist einen Adapter 21 auf, welcher dazu dient, eine feste und einfach herstellbare aber lösbare Verbindung der Leuchte 2 mit der Halterung 1 zu erzeugen. Der Adapter 21 erstreckt sich von einem Gehäuse 20 der Leuchte 2 in der Richtung der Hochachse Z zur Halterung 1 hin. Der Adapter 21 weist in der Ebene der Längsachse X und Querachse Y die Kontur einer Raute auf, so dass der Adapter 21 in einer ersten Drehstellung um die Hochachse Z in die Aufnahmeöffnung 13 in Richtung der Hochachse Z eingeführt werden kann. Durch Drehung des Adapters 21 um die Hochachse Z in eine zweite Drehstellung kann der Adapter 21 in der Aufnahmeöffnung 13 gehalten werden. Hierzu weist der Adapter 21 zwei seitliche Vorsprünge 23 auf, die auch als Adapternasen 23 bezeichnet werden können. Die Adapternasen 23 sind derart ausgestaltet und am Adapter 21 seitlich angeordnet, dass sie in der zweiten Drehstellung in die Vorsprungaufnahmen 14 der Halterung 1 eingreifen und von diesen umgriffen werden können. Der Adapter 21 weist ferner zwei elektrische Kontaktelemente 22 auf, die derart ausgestaltet und am Adapter 21 seitlich angeordnet sind, dass sie in der zweiten Drehstellung in die Öffnungen der elektrischen Isolationen 11 eingreifen und die elektrischen Leiter 12 elektrisch leitfähig kontaktieren können. Die elektrischen Kontaktelemente 22 des Adapters 21 sind mittels elektrischer Leitungen 28 (vgl. z.B.
In dieser zweiten Drehstellung des Adapters 21 kann die Leuchte 2 mittels des Adapters 21 sicher in der Schienenhalterung 1 gehalten und betrieben werden. Um den Adapter 21 in dieser zweiten Drehstellung zu sichern, weist die Leuchte 2 zwei Befestigungsmittel 24 in Form von Gehäusenasen 24 auf, die einstückig mit dem Gehäuse 20 ausgebildet sind. Die Gehäusenasen 24 erstrecken sich in Richtung der Hochachse Z über die adapterseitige Gehäuseseite 29 soweit hinaus und sind in der Querachse Y derart ausgestaltet, dass die Gehäusenasen 24 in der zweiten Drehstellung des Adapters 21 in die Aufnahmeöffnung 13 eingreifen und bei einer festen Verbindung zwischen Gehäuse 20 und Adapter 21 eine Drehbewegung des Adapters 21 aus der zweiten Drehstellung heraus vermeiden können. Die adapterseitige Gehäuseseite 29 liegt dabei mit ihrer Kante bzw. Fläche an der Schiene 10 an.In this second rotational position of the
Um nun seinerseits das Gehäuse 20 in dieser Stellung, in der die zweite Drehstellung des Adapters 21 durch die Gehäusenasen 24 gesichert wird, zu sichern, ist es bisher bekannt, eine Schraubverbindung zwischen dem Adapter 21 und dem Gehäuse 20 herzustellen, siehe
Nachdem der Adapter 21 in der zweiten Drehstellung in die Schienenhalterung 1 eingegriffen hat, kann dieser Zustand gemäß dem Stand der Technik dadurch gesichert werden, dass das Gehäuse 20 in Richtung der Hochachse Z zur Schienenhalterung 1 über den Adapter 21 bewegt wird, so dass die Gehäusenasen 24 in die Aufnahmeöffnung 13 eingreifen. Da bei einer Deckenmontage das Gehäuse 20 hierbei entgegen der Richtung der Schwerkraft bewegt werden muss, würde sich dieser Sicherungszustand von alleine wieder lösen. Daher ist dann die Mutter 27 auf das Außengewinde 25 aufzuschrauben, so dass der Eingriff der Gehäusenasen 24 in die Aufnahmeöffnung 13 hierdurch fixiert werden kann.After the
Nachteilig ist hierbei, dass gerade bei einer Deckenmontage das Gehäuse 20 so lange mit einer Hand gegen die Schiene 10 gedrückt werden muss, bis mit der anderen Hand die Mutter 27 auf das Außengewinde 25 aufgeschraubt wurde. Dies ist umständlich, unbequem und kann für die Arme des Benutzers sehr schnell ermüdend sein.The disadvantage here is that just in a ceiling mounting the
Erfindungsgemäß wird stattdessen vorgeschlagen, den Adapter 21 über ein Federelement 30 in Form einer Kegeldruckfeder 30 mit dem Gehäuse 20 bzw. dessen Gehäusenasen 24 zu verbinden, so dass eine einfache und bequeme einhändige Montage der Leuchte 2 in der Schienenhalterung 1 erfolgen kann. Dies wird nun im Zusammenhang mit den

In Richtung der Hochachse Z ist zwischen der Adapterplatte 35 und dem beweglichen Anschlagselement 33 ein weiteres Anschlagselement 31 angeordnet, welches feststehend mit dem Gehäuse 20 verbunden ist und daher auch als feststehendes Anschlagselement 31 bezeichnet werden kann. Die starre Verbindung zwischen der Adapterplatte 35 und dem beweglichen Anschlagselement 33 ist hierzu durch eine Öffnung des feststehenden Anschlagselements 31 hindurchgeführt. Zwischen den beiden Anschlagselementen 31, 33 ist das Federelement 30 als Kegeldruckfeder 30 angeordnet, so dass eine Relativbewegung der beiden Anschlagselemente 31, 33 entlang der Hochachse Z gegen die Federkraft der Kegeldruckfeder 30 erfolgen kann. Das feststehende Anschlagselement 31 weist ein Drehbegrenzungselement 32 in Form eines Bolzens 32 und das bewegliche Anschlagselement 33 ein Drehbegrenzungselement 34a, 34b in Form zweier Stufen 34a, 34b auf, die in Umfangsrichtung des beweglichen Anschlagselements 33 ca. 180° zueinander versetzt sind.
