Definitions
- the invention relates to a device for fixing a lamp to a fixed space surface, in particular to a busbar adapter, wherein the lamp is pivotable about a first and about a second spatial axis relative to the fixed space surface and wherein a first and a second locking means is provided for Schwenkarret ist.
- the Applicant known device makes it possible to fix the lamp on a fixed space, for example on a busbar adapter, adjustable in rotation and to lock in a desired rotational position.
- the busbar adapter is held in a busbar, which is attached to a building surface, for example on a ceiling wall.
- the known device according to Fig. 2 of the EP 0 567 739 B1 a substantially L-shaped bracket with two Drehverstellvoridesen A and B, with which the lamp is pivotable about a vertical axis of space y and about a horizontal axis of space x.
- Each of the two Drehverstellvortechnischen A and B can be schwenkarretieren with a locking means to secure the set position of the lamp permanently. .
- the holder is rotatably connected via a hub element with a middle part fastened to the busbar adapter.
- the hub member is provided via spoke-like struts with a coaxial with the hub arranged annular disc.
- the annular disc On its underside, the annular disc has a toothing, which cooperates with a pinion which is rotatably mounted on a bolt.
- the bolt passes through a hole in one of the bracket attached console.
- the pinion runs with a relative movement between the bracket and busbar adapter with no resistance. It can be but by means of a knurled nut, which exerts a tensile force on the bearing pin, set against the console. In this way, a pivot lock of the rotary adjustment device A is effected.
- the second Drehverstellvortechnische B works in principle as the just described Drehverstellvortechnische A, wherein the toothing is arranged in a segmental arc of the holder and the pinion on an arm attached to the lamp.
- the object of the invention is to develop the known device such that their handling is facilitated.
- the invention solves this problem with the features of claim 1, in particular with those of the characterizing part and is accordingly characterized in that the device is associated with an actuating element with which both locking means are jointly addressed.
- the principle of the invention consists essentially in the fact that the lamp pivotable about two spatial axes can be locked in the set position after adjustment or alignment with the aid of only one actuating element.
- the adjustment of the device according to the invention is thus particularly time-saving, because only one actuator must be operated. This is particularly important when many lights are to be adjusted, as is the case in a museum, for example. Here, the lights must be regularly re-adjusted for changing exhibitions with different exhibits.
- the device according to the invention is used to attach a lamp to a solid surface, for example on a wall or a ceiling of a building.
- the lamp can either be attached directly to the building surface or, for example, via a busbar adapter to be fixed to a busbar fixed side or a comparable carrier element.
- the actuator may be formed of very simple mechanical elements, such as screws or levers.
- commercial, commercially available elements come into question.
- As a locking means are all components or component elements into consideration, which are suitable to produce a non-positive and / or positive locking, releasable connection and to ensure in this way a locking of the lamp in a set position.
- US-A-5,845,885 goes out a coupling device in which a relatively movable part can be set to a relatively fixed object.
- the device comprises two housing shells, which can be clamped against each other.
- the publication does not show an actuating element which, with the interposition of wedge surfaces, enables a common response of two locking means.
- this document does not show a soft deflection of an axial movement of the actuating element in a movement of an actuator with two different directional components.
- US-A-5,140,507 goes out an adjustment of a spotlight.
- An operator can set a standing on the floor, for example, a ceiling mounted light over an elongated trained adjustment.
- the adjusting element has two axially spaced-apart handles, which can be rotated in opposite directions or together.
- the interposition of wedge surfaces in order to address jointly by means of an actuating element two locking means, is also not apparent from this document.
- At least one actuator is associated with the actuating element for the response of the locking means.
- Such an actuator may serve to bridge the distance between the actuator and the locking means. This has the advantage that the position of the locking means is freely selectable. They can be located away from the actuator.
- At least one locking means is arranged on the actuator, which reduces the cost of manufacturing, assembly and storage.
- the locking means can be made in one piece with the actuator, for example, cohesively.
- both locking means are arranged on the actuator. This allows a particularly simple construction and construction.
- At least one locking means can according to another embodiment of the invention non-positively and / or positively cooperate with a corresponding antidote.
- the locking means may be arranged on a hinge part and the counter-agent on the other relative to the movable joint part. The cooperation of the locking means and the antidote may allow locking of the joint.
- the frictional connection between a clamping surface assigned to the locking means and a counter-clamping surface associated with the antivessel can, on the one hand, serve to lock the pivoting position of the luminaire.
- a frictional force to provide a resistance can be achieved by the traction when not pivotally locked light, which allows self-locking of the lamp during the adjustment, so that in its pivoting position set light can at least temporarily retain their set position due to the frictional resistance.
- the operator who actuates the actuating element for pivotal locking of the lamp for example, with one hand, therefore does not have to hold the lamp in its position with her other hand, but can work comfortably with one hand.
- An alternative to the traction alternative possible positive connection between the locking means and the antidote has the advantage of a particularly secure locking, but may require a larger adjustment.
- the antidote is fixed relative to the solid surface and / or arranged relative to the lamp.
- a first antidote is fixed relative to the space-fixed surface (fixed in space) arranged and a second antidote fixed relative to the luminaire.
- the attachment of the first antidote to the space fixed surface e.g. directly on a busbar adapter or on an associated bolt or the like, and an attachment of the second counter-agent takes place directly on the luminaire. This allows a simple construction and installation of the device, which can be connected via their antidote room side or light side.

- a clamping jaws or jaw-like design of the locking means is possible, with the particularly high clamping forces can be applied, which can permanently lock even heavy lights, eg very heavy spotlights in the selected pivot position.
- the curved surfaces form a pair of surfaces, which is preferably matched and matched to one another such that very large surface areas come to rest in the clamped state. This can be applied particularly large holding forces.
- a locking means with a clamping surface is associated with a light-side counter-agent with a counter-clamping surface, wherein the clamping surface overlaps or spans the counter-clamping surface.
- the inner of the two mutually to be clamped surfaces of the surface pair is a preferably convexly curved counter-clamping surface, which is overlapped by the preferably correspondingly concave curved clamping means-side clamping surface.
- the light-side counter-clamping surface is engaged behind by an actuator-side plug-extension.
- the extension is arranged for example in a foot region of the actuator, which, as will be explained later, may be formed by a housing shell.
- the plug-in projection with a free end, on which the extension is, advance be inserted between the other housing shell and the light-side counter-clamping surface, so that subsequently a pivoting of the actuator can be performed. If now a contact surface described later displaced, is the actuator held captive on the other housing shell.
- a manageable unit which is composed of the actuator and the other housing shell, and the total is fastened to the lamp.
- the clamping surface engages over the counter-clamping surface over an angular range of several 10 °.
- the optimum angle range depends on the curvature of the clamping surface and the counter-clamping surface.
- manufacturing tolerances play a role that can be controlled particularly well due to the curved clamping surface and the counter-clamping surface. It is important in this context that not only a point-like or line-like contact between clamping surface and counter-clamping surface occurs, but as large as possible to transfer large clamping forces can.
- a light-side counter-agent on a bearing eye for the second spatial axis (pivot axis).
- the actuator e.g. the first housing shell, after insertion of the plug-in extension in the space between the counter-clamping surface and the second housing shell relative to the second housing shell are clamped such that the two housing shells are mounted to each other after bracing and the preassembled unit via mounting lugs, preferably also located on the light-side antidote, is connected to the lamp.
- the device has a diaphragm for covering a on the luminaire-side antidote. This allows an optically advantageous view of the detection means and the corresponding antidote and protection against dirt.
- a locking means is arranged in a head region of the actuator, which cooperates with a fixed relative to the space-fixed surface arranged antidote.
- the fixedly arranged relative to the space-fixed surface antidote is hereinafter referred to as room-side antidote and differs from the light-side antidote to be attached to the lamp.
- the room-side antidote in particular in the form of an annular body, is arranged between two clamping jaws.
- a first clamping jaw may be formed by the first locking means, in particular on the actuator, and a second clamping jaw may be formed by the second housing shell.

- the actuator speaks directly to a provided with the contact surface component and moves it. This allows a particularly simple design and the application of high actuation forces on the contact surface. Accordingly, the contact surface on the mating contact surface can also transmit large forces. This makes it possible that over the actuator large forces are exerted to lock the locking means.
- a further embodiment of the invention provides that the actuating element acts on a first component of the thrust element arrangement, which responds by interposition of a spring element provided with the contact surface second component.
- the spring allows the application of a variable locking force, which is also precisely adjustable.
- the contact surface and the mating contact surface of wedge surfaces are formed, which deflect an axial movement of the second component soft like a movement of the actuator with two different directional components.
- the contact surface can be between a rest position in which the lamp is pivotable about both spatial axes, and a working position in which locks the lamp to the spatial axes is, be relocatable. Between these extreme positions of the contact surface, there are other positions of the contact surface in which the lamp is pivotable against a more or less large resistance around the spatial axes.

- the crucial difference between the Drehverstellvortechnisch B of the second embodiment and the Drehverstellvortechnisch B of the first embodiment is that the inner and outer bearing shell are reversed.
- the outer bearing shell is associated with the actuator, whereby greater holding forces can be exercised. It is essential that the clamping surface overlaps the counter-clamping surface.

- the housing shell 14 can now, obliquely inclined, be moved toward the housing shell 14 to this, the plug 51 is inserted into the space Z between the counter-clamping surface 53 and the housing shell 14.
- the housing shell 15 can be pivoted in a clockwise direction relative to the housing shell 14 such that the two housing shells 14 abut each other.
- the mating contact surface 34 could thereby reach behind the contact surface 33 as a result of the pivoting movement in the x-direction. If now the threaded screw 27 is actuated and the component 32 is moved in the x-direction, the contact surface 33 comes into contact with the mating contact surface 34.

- the Housing shell 15 can still be displaced relative to the housing shell 14 in this pre-assembled state with movement play.
- the threaded screw 27 only needs to be operated. This happens primarily but only when the radiator 13 is connected to the device 10.
- a release of the actuating element 27 by rotation in the opposite direction can cancel a pivot lock of the radiator 13 about the two spatial axes S 1 and S 2 in the manner described above.
- the guided in a slide track member 32 moves upon rotation of the actuating element 27 about its longitudinal axis with respect Fig. 10 to the left, so that the wedge surfaces 33 and 34 move away from each other.
- the Drehverstellvorraumen A and B are solved.
- Fig. 10 indicates that when loosening the device 10 by turning the actuating element 27 prevents a stop element that the threaded screw 27 rotates out of the device 10 in the x direction. If the device 10 has been previously clamped with particularly large actuation forces, the two wedge surfaces 33 and 34 may be with each other with very large self-holding or braking forces. If now the actuator 27 are released, the component 32 may remain in place relative to the housing shell 15 and may unintentionally the threaded rod 27 with respect to Fig. 10 to the right, ie in the x-direction out of the device 10. This prevents as a stop element, a lock nut 54 with respect to their Fig. 10 right Ringstimseite on the inside 55 of the housing shell 14 can strike.
- the lock nut 54 After the threaded rod 27 is inserted in the assembly of the device 10 through the housing shell 14, the lock nut 54 from the respect Fig. 10 left side be screwed and then takes a fixed axial position on the threaded rod 27 a. The nut 54 then turns always with the threaded screw 27 and prevented by striking the inside 55 of the housing shell 14, a turning out of the actuating element 27 of the device 10th
- the lock nut 54 is set at a distance of, for example, about 0.5 mm to the inside 55, so that the actuator 27 can be operated easily due to the movement play.
- the housing shell 14 is attached to the antidote 46 to the radiator 13. Subsequently, electrical leads can be inserted into the cavity H of the housing shell 14 and connected to the radiator 13. Only last, the housing shell 15 can be fixed to the housing shell 14, wherein the aforementioned pivoting operation of the housing shell 15 relative to the housing shell 14 after insertion of the extension 51 in the intermediate space Z is equally accomplished.

An ihrer Unterseite weist die Kreisringscheibe eine Verzahnung auf, die mit einem Ritzel zusammenwirkt, das auf einem Bolzen drehbar gelagert ist. Der Bolzen durchgreift eine Bohrung einer an der Halterung befestigten Konsole. Das Ritzel läuft bei einer Relativbewegung zwischen Halterung und Stromschienenadapter widerstandslos mit. Es lässt sich aber mittels einer Rändelmutter, die eine Zugkraft auf den Lagerbolzen ausübt, gegen die Konsole festsetzen. Auf diese Weise wird eine Schwenkarretierung der Drehverstellvorrichtung A bewirkt.For this purpose, in the first rotary adjusting device A, the holder is rotatably connected via a hub element with a middle part fastened to the busbar adapter. The hub member is provided via spoke-like struts with a coaxial with the hub arranged annular disc. On its underside, the annular disc has a toothing, which cooperates with a pinion which is rotatably mounted on a bolt. The bolt passes through a hole in one of the bracket attached console. The pinion runs with a relative movement between the bracket and busbar adapter with no resistance. It can be but by means of a knurled nut, which exerts a tensile force on the bearing pin, set against the console. In this way, a pivot lock of the rotary adjustment device A is effected.
Die zweite Drehverstellvorrichtung B funktioniert prinzipiell wie die soeben beschriebene Drehverstellvorrichtung A, wobei die Verzahnung in einem Segmentbogen der Halterung und das Ritzel an einem an der Leuchte befestigten Arm angeordnet ist.The second Drehverstellvorrichtung B works in principle as the just described Drehverstellvorrichtung A, wherein the toothing is arranged in a segmental arc of the holder and the pinion on an arm attached to the lamp.
Die zuvor beschriebene Vorrichtung hat sich umfangreich bewährt.The device described above has proven itself extensively.
Ausgehend von diesem Stand der Technik besteht die Aufgabe der Erfindung darin, die bekannte Vorrichtung derart weiterzubilden, dass ihre Handhabung erleichtert wird.Based on this prior art, the object of the invention is to develop the known device such that their handling is facilitated.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruches 1, insbesondere mit denen des Kennzeichenteils und ist demgemäss dadurch gekennzeichnet, dass der Vorrichtung ein Betätigungselement zugeordnet ist, mit dem beide Feststellmittel gemeinsam ansprechbar sind.The invention solves this problem with the features of claim 1, in particular with those of the characterizing part and is accordingly characterized in that the device is associated with an actuating element with which both locking means are jointly addressed.
Das Prinzip der Erfindung besteht im wesentlichen darin, dass die um zwei Raumachsen schwenkbare Leuchte nach dem Justieren oder Ausrichten mit Hilfe lediglich eines Betätigungselementes in der eingestellten Position arretierbar ist. Der Einstellvorgang der erfindungsgemäßen Vorrichtung ist somit besonders zeitsparend, weil nur noch ein Betätigungselement bedient werden muss. Das spielt insbesondere dann eine Rolle, wenn viele Leuchten zu justieren sind, wie es beispielsweise in einem Museum der Fall ist. Hier müssen für wechselnde Ausstellungen mit unterschiedlichen Exponaten die Leuchten regelmäßig neu justiert werden.The principle of the invention consists essentially in the fact that the lamp pivotable about two spatial axes can be locked in the set position after adjustment or alignment with the aid of only one actuating element. The adjustment of the device according to the invention is thus particularly time-saving, because only one actuator must be operated. This is particularly important when many lights are to be adjusted, as is the case in a museum, for example. Here, the lights must be regularly re-adjusted for changing exhibitions with different exhibits.
Das Lösen und Arretieren der Betätigungselemente zum Justieren der Leuchten war bisher zeitaufwendig. Mit der erfindungsgemäßen Vorrichtung ist diese Arbeit schneller und komfortabler durchführbar. Es kann nahezu die Hälfte der Arbeitszeit eingespart werden.The release and locking of the actuators to adjust the lights has been time consuming. With the device according to the invention, this work is faster and easier to carry out. Almost half the working time can be saved.
Die erfindungsgemäße Vorrichtung dient der Befestigung einer Leuchte an einer raumfesten Fläche, beispielsweise an einer Wand oder einer Decke eines Gebäudes. Die Leuchte kann dabei entweder unmittelbar an der Gebäudefläche befestigt werden oder, beispielsweise über einen Stromschienen-Adapter, an einer wandseitig festgelegten Stromschiene oder einem vergleichbaren Trägerelement festgelegt werden.The device according to the invention is used to attach a lamp to a solid surface, for example on a wall or a ceiling of a building. The lamp can either be attached directly to the building surface or, for example, via a busbar adapter to be fixed to a busbar fixed side or a comparable carrier element.
Das Betätigungselement kann von sehr einfachen mechanischen Elementen, wie beispielsweise Schrauben oder Hebeln, gebildet sein. Insbesondere kommen auch handelsübliche, kommerziell erhältliche Elemente in Frage. Als Feststellmittel kommen alle Bauteile oder Bauteilelemente in Betracht, die geeignet sind eine kraft- oder / und formschlüssige, lösbare Verbindung herzustellen und auf diese Weise eine Arretierung der Leuchte in einer eingestellten Position zu gewährleisten.The actuator may be formed of very simple mechanical elements, such as screws or levers. In particular, commercial, commercially available elements come into question. As a locking means are all components or component elements into consideration, which are suitable to produce a non-positive and / or positive locking, releasable connection and to ensure in this way a locking of the lamp in a set position.

Gemäß einer Ausgestaltung der Erfindung ist dem Betätigungselement zum Ansprechen der Feststellmittel wenigstens ein Stellglied zugeordnet. Ein solches Stellglied kann dazu dienen, die Distanz zwischen dem Betätigungselement und den Feststellmitteln zu überbrücken. Das hat den Vorteil, dass die Position der Feststellmittel frei wählbar ist. Sie können entfernt vom Betätigungselement angeordnet werden.According to one embodiment of the invention, at least one actuator is associated with the actuating element for the response of the locking means. Such an actuator may serve to bridge the distance between the actuator and the locking means. This has the advantage that the position of the locking means is freely selectable. They can be located away from the actuator.
Dabei ist es vorteilhaft, wenn das Stellglied beide Feststellmittel zugleich anspricht. Diese Lösung ist in konstruktiver Hinsicht besonders vorteilhaft und erleichtert die Montage und Lagerhaltung, da an Stelle von zwei getrennten Stellgliedern nur noch ein Stellglied an der Vorrichtung angebracht werden muss.It is advantageous if the actuator both locking means responds at the same time. This solution is structurally particularly advantageous and facilitates assembly and storage, since instead of two separate actuators only one actuator must be attached to the device.
Des Weiteren ist es möglich, dass an dem Stellglied mindestens ein Feststellmittel angeordnet ist, was den Aufwand für Fertigung, Montage und Lagerhaltung herabsetzt. So kann das Feststellmittel zusammen mit dem Stellglied einstückig, beispielsweise stoffschlüssig, hergestellt werden.Furthermore, it is possible that at least one locking means is arranged on the actuator, which reduces the cost of manufacturing, assembly and storage. Thus, the locking means can be made in one piece with the actuator, for example, cohesively.
Weiter vorzugsweise sind beide Feststellmittel an dem Stellglied angeordnet. Dies ermöglicht eine besonders einfache Bauweise und Konstruktion.Further preferably, both locking means are arranged on the actuator. This allows a particularly simple construction and construction.
Wenigstens ein Feststellmittel kann gemäß einer weiteren Ausgestaltung der Erfindung kraft- und/oder formschlüssig mit einem korrespondierenden Gegenmittel zusammenwirken. Ist ein Verschwenken der Leuchte mittels der Drehverstellvorrichtungen, z.B. mittels drehbeweglicher Gelenke, möglich, kann das Feststellmittel an einem Gelenkteil und das Gegenmittel an dem anderen relativ dazu beweglichen Gelenkteil angeordnet sein. Das Zusammenwirken der Feststellmittel und der Gegenmittel kann ein Arretieren des Gelenks ermöglichen.At least one locking means can according to another embodiment of the invention non-positively and / or positively cooperate with a corresponding antidote. Is a pivoting of the lamp by means of Drehverstellvorrichtungen, e.g. by means of rotatable joints, possible, the locking means may be arranged on a hinge part and the counter-agent on the other relative to the movable joint part. The cooperation of the locking means and the antidote may allow locking of the joint.
Wird die Arretierung von einem Kraftschluss bewirkt, so hat das den Vorteil, dass dafür lediglich ein geringer Verstellweg zwischen Feststellmittel und Gegenmittel notwendig ist. Der Kraftschluss zwischen einer dem Feststellmittel zugeordneten Spannfläche und einer dem Gegenmittel zugeordneten Gegenspannfläche kann einerseits zur Arretierung der Schwenkposition der Leuchte dienen. Andererseits kann durch den Kraftschluss bei nicht schwenk-arretierter Leuchte auch eine Reibungskraft zur Bereitstellung eines Widerstandes erzielt werden, der eine Selbsthemmung der Leuchte während der Justage ermöglicht, so dass die in ihrer Schwenkposition eingestellte Leuchte zumindest kurzzeitig ihre eingestellte Position aufgrund des Reibungswiderstandes beibehalten kann. Die Bedienperson, die zur Schwenkarretierung der Leuchte z.B. mit einer Hand das Betätigungselement betätigt, muss daher nicht mit ihrer anderen Hand die Leuchte in ihrer Position festhalten, sondern kann auf komfortable Weise einhändig arbeiten.If the locking is effected by a frictional connection, this has the advantage that only a small adjustment path between the locking means and the antidote is necessary for this. The frictional connection between a clamping surface assigned to the locking means and a counter-clamping surface associated with the antivessel can, on the one hand, serve to lock the pivoting position of the luminaire. On the other hand, a frictional force to provide a resistance can be achieved by the traction when not pivotally locked light, which allows self-locking of the lamp during the adjustment, so that in its pivoting position set light can at least temporarily retain their set position due to the frictional resistance. The operator who actuates the actuating element for pivotal locking of the lamp, for example, with one hand, therefore does not have to hold the lamp in its position with her other hand, but can work comfortably with one hand.
Ein zu dem Kraftschluss alternativ möglicher Formschluss zwischen Feststellmittel und Gegenmittel hat den Vorteil einer besonders sicheren Arretierung, setzt allerdings unter Umständen einen größeren Verstellweg voraus.An alternative to the traction alternative possible positive connection between the locking means and the antidote has the advantage of a particularly secure locking, but may require a larger adjustment.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist das Gegenmittel fest relativ zu der raumfesten Fläche und/oder relativ zu der Leuchte angeordnet. Weiter vorteilhafterweise ist ein erstes Gegenmittel fest relativ zu der raumfesten Fläche (raumfest) angeordnet und ein zweites Gegenmittel fest relativ zu der Leuchte angeordnet. Auf diese Weise kann die Befestigung des ersten Gegenmittels an der raumfesten Fläche, z.B. unmittelbar an einem Stromschienen-Adapter oder an einem zugehörigen Bolzen od. dgl., erfolgen und eine Befestigung des zweiten Gegenmittels unmittelbar an der Leuchte erfolgen. Dies ermöglicht eine einfache Konstruktion und Montage der Vorrichtung, die über ihre Gegenmittel raumseitig bzw. leuchtenseitig angebunden werden kann.According to an advantageous embodiment of the invention, the antidote is fixed relative to the solid surface and / or arranged relative to the lamp. Further advantageously, a first antidote is fixed relative to the space-fixed surface (fixed in space) arranged and a second antidote fixed relative to the luminaire. In this way, the attachment of the first antidote to the space fixed surface, e.g. directly on a busbar adapter or on an associated bolt or the like, and an attachment of the second counter-agent takes place directly on the luminaire. This allows a simple construction and installation of the device, which can be connected via their antidote room side or light side.
Das Feststellmittel und das korrespondierende Gegenmittel können mit gegeneinander verspannbaren Flächen versehen sein. Diese Ausgestaltung der Erfindung ermöglicht es, die Vorrichtung konstruktiv einfach zu gestalten und die Schwenkarretierung mit einer geringen Anzahl von Bauteilen zu gewährleisten.The locking means and the corresponding antidote may be provided with mutually bracing surfaces. This embodiment of the invention makes it possible to design the device structurally simple and to ensure the pivot lock with a small number of components.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist eine Spannfläche eines Feststellmittels im Wesentlichen konkav gekrümmt ausgebildet. Dies bietet die Möglichkeit, dass die der Spannfläche zugehörige Gegenspannfläche im Wesentlichen konvex gekrümmt ausgebildet sein kann. Mit dieser Ausgestaltung der Erfindung wird eine spannbacken- oder klemmbackenartige Ausbildung der Feststellmittel möglich, mit der besonders hohe Spannkräfte aufgebracht werden können, die auch schwere Leuchten, z.B. sehr schwere Strahler, in der angewählten Schwenkposition dauerhaft arretieren können. Die gekrümmten Flächen bilden ein Flächenpaar, welches vorzugsweise derart aufeinander abgestimmt und abgepasst ist, dass im verspannten Zustand sehr große Flächenbereiche aufeinander zum Anliegen kommen. Damit können besonders große Haltekräfte aufgebracht werden.According to an advantageous embodiment of the invention, a clamping surface of a locking means is formed substantially concave curved. This offers the possibility of having the clamping surface associated counter-clamping surface may be formed substantially convex curved. With this embodiment of the invention, a clamping jaws or jaw-like design of the locking means is possible, with the particularly high clamping forces can be applied, which can permanently lock even heavy lights, eg very heavy spotlights in the selected pivot position. The curved surfaces form a pair of surfaces, which is preferably matched and matched to one another such that very large surface areas come to rest in the clamped state. This can be applied particularly large holding forces.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist einem Feststellmittel mit einer Spannfläche ein leuchtenseitiges Gegenmittel mit einer Gegenspannfläche zugeordnet, wobei die Spannfläche die Gegenspannfläche übergreift oder überspannt. Bei dieser Ausgestaltung der Erfindung ist die innere der beiden gegeneinander zu verspannenden Flächen des Flächenpaares eine vorzugsweise konvex gekrümmte Gegenspannfläche, die von der vorzugsweise entsprechend konkav gekrümmten feststellmittelseitigen Spannfläche übergriffen wird. Mit dieser Anordnung können besonders große Haltekräfte erzielt werden.According to a further advantageous embodiment of the invention, a locking means with a clamping surface is associated with a light-side counter-agent with a counter-clamping surface, wherein the clamping surface overlaps or spans the counter-clamping surface. In this embodiment of the invention, the inner of the two mutually to be clamped surfaces of the surface pair is a preferably convexly curved counter-clamping surface, which is overlapped by the preferably correspondingly concave curved clamping means-side clamping surface. With this arrangement, particularly large holding forces can be achieved.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die leuchtenseitige Gegenspannfläche von einem stellgliedseitigen Steck-Fortsatz hintergriffen. Der Fortsatz ist beispielsweise in einem Fußbereich des Stellgliedes angeordnet, welches, wie später erläutert wird, von einer Gehäuseschale gebildet sein kann. Zur Montage der beiden Gehäuseschalen aneinander kann der Steck-Fortsatz mit einem freien Ende, an dem sich der Fortsatz befindet, voraus, zwischen die andere Gehäuseschale und die leuchtenseitige Gegenspannfläche eingesteckt werden, so dass nachfolgend eine Verschwenkung des Stellgliedes durchgeführt werden kann. Wird nun eine später beschriebene Kontaktfläche verlagert, ist das Stellglied unverlierbar an der anderen Gehäuseschale gehalten. Damit wird eine handhabbare Baueinheit erreicht, die sich aus dem Stellglied und der anderen Gehäuseschale zusammensetzt, und die insgesamt an der Leuchte befestigbar ist.According to a further advantageous embodiment of the invention, the light-side counter-clamping surface is engaged behind by an actuator-side plug-extension. The extension is arranged for example in a foot region of the actuator, which, as will be explained later, may be formed by a housing shell. For mounting the two housing shells together, the plug-in projection with a free end, on which the extension is, advance, be inserted between the other housing shell and the light-side counter-clamping surface, so that subsequently a pivoting of the actuator can be performed. If now a contact surface described later displaced, is the actuator held captive on the other housing shell. In order for a manageable unit is achieved, which is composed of the actuator and the other housing shell, and the total is fastened to the lamp.
Vorteilhafterweise übergreift die Spannfläche die Gegenspannfläche über einen Winkelbereich von mehreren 10°. Der optimale Winkelbereich hängt allerdings von der Krümmung der Spannfläche und der Gegenspannfläche ab. Auch spielen Fertigungstoleranzen eine Rolle, die infolge der gekrümmten Spannfläche und der Gegenspannfläche besonders gut beherrschbar sind. Wichtig ist in diesem Zusammenhang, dass nicht nur eine punktartige oder linienartige Berührung zwischen Spannfläche und Gegenspannfläche auftritt, sondern eine möglichst großflächige, um große Klemmkräfte übertragen zu können.Advantageously, the clamping surface engages over the counter-clamping surface over an angular range of several 10 °. However, the optimum angle range depends on the curvature of the clamping surface and the counter-clamping surface. Also, manufacturing tolerances play a role that can be controlled particularly well due to the curved clamping surface and the counter-clamping surface. It is important in this context that not only a point-like or line-like contact between clamping surface and counter-clamping surface occurs, but as large as possible to transfer large clamping forces can.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung weist ein leuchtenseitiges Gegenmittel ein Lagerauge für die zweite Raumachse (Schwenkachse) auf. Dies ermöglicht eine besonders einfache Konstruktion derart, dass das leuchtenseitige Gegenmittel, also in der Terminologie der vorliegenden Anmeldung das zweite Gegenmittel, über das Lagerauge an der zweiten Gehäuseschale befestigbar ist. Das Stellglied, also z.B. die erste Gehäuseschale, kann nach dem Einstecken des Steckfortsatzes in den Zwischenraum zwischen der Gegenspannfläche und der zweiten Gehäuseschale relativ zu der zweiten Gehäuseschale derartig verspannt werden, dass die beiden Gehäuseschalen nach dem Verspannen aneinander montiert sind und die vormontierte Baueinheit über Befestigungsansätze, die sich vorzugsweise ebenfalls an dem leuchtenseitigen Gegenmittel befinden, mit der Leuchte verbunden wird.According to a further advantageous embodiment of the invention, a light-side counter-agent on a bearing eye for the second spatial axis (pivot axis). This allows a particularly simple construction such that the luminaire-side antidote, that is, in the terminology of the present application, the second antidote, on the bearing eye on the second housing shell can be fastened. The actuator, e.g. the first housing shell, after insertion of the plug-in extension in the space between the counter-clamping surface and the second housing shell relative to the second housing shell are clamped such that the two housing shells are mounted to each other after bracing and the preassembled unit via mounting lugs, preferably also located on the light-side antidote, is connected to the lamp.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die Vorrichtung eine Blende zur Abdeckung eines leuchtenseitigen Gegenmittels auf. Dies ermöglicht eine in optischer Hinsicht vorteilhafte Blickverhinderung auf das Feststellmittel und das entsprechende Gegenmittel sowie einen Schutz vor Schmutz.According to a further advantageous embodiment of the invention, the device has a diaphragm for covering a on the luminaire-side antidote. This allows an optically advantageous view of the detection means and the corresponding antidote and protection against dirt.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist in einem Kopfbereich des Stellgliedes ein Feststellmittel angeordnet, welches mit einem fest relativ zu der raumfesten Fläche angeordneten Gegenmittel kooperiert. Das fest relativ zu der raumfesten Fläche angeordnete Gegenmittel wird im Folgenden als raumseitiges Gegenmittel bezeichnet und unterscheidet sich insofern von dem an der Leuchte zu befestigenden leuchtenseitigen Gegenmittel.According to a further advantageous embodiment of the invention, a locking means is arranged in a head region of the actuator, which cooperates with a fixed relative to the space-fixed surface arranged antidote. The fixedly arranged relative to the space-fixed surface antidote is hereinafter referred to as room-side antidote and differs from the light-side antidote to be attached to the lamp.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das raumseitige Gegenmittel, insbesondere in Form eines Ringkörpers, zwischen zwei Spannbacken angeordnet. Eine erste Spannbacke kann von dem ersten Feststellmittel, insbesondere an dem Stellglied, und eine zweite Spannbacke kann von der zweiten Gehäuseschale gebildet sein. Mithin ist das raumseitige Gegenmittel zwischen zwei Spannbacken einspannbar und kann auf diese Weise besonders sicher arretiert werden, da durch die zwei Spannbacken große Klemmkräfte ausgeübt werden können.According to a further advantageous embodiment of the invention, the room-side antidote, in particular in the form of an annular body, is arranged between two clamping jaws. A first clamping jaw may be formed by the first locking means, in particular on the actuator, and a second clamping jaw may be formed by the second housing shell. Thus, the room-side antidote between two jaws can be clamped and can be locked in this way very safe because large clamping forces can be exerted by the two jaws.
Gemäß einer weiteren Ausgestaltung der Erfindung wirkt das Betätigungselement mit einer Schubelementanordnung zusammen. Mit Hilfe der Schubelementanordnung lässt sich eine Bewegung des Betätigungselementes beispielsweise auf das Stellglied übertragen.According to a further embodiment of the invention, the actuating element cooperates with a thrust element arrangement. With the help of the thrust element arrangement, a movement of the actuating element can be transmitted to the actuator, for example.
Zum Ansprechen mindestens eines Feststellmittels kann der Schubelementanordnung gemäß einer weiteren Ausgestaltung der Erfindung wenigstens eine Kontaktfläche zugeordnet sein. Mit Hilfe der Kontaktfläche läßt sich auf einfache Art und Weise ein Stellglied betätigen, das mit der Kontaktfläche in Verbindung steht.To respond to at least one locking means of the thrust element assembly according to another embodiment of the invention may be associated with at least one contact surface. With the help of the contact surface can be actuated in a simple manner, an actuator which is in communication with the contact surface.
Die Kontaktfläche kann mit einer an dem Stellglied angeordneten Gegenkontaktfläche zusammenwirken. Das Zusammenwirken von Kontaktfläche und Gegenkontaktfläche gestattet es auf vorteilhafte Weise, die von der Schubelementeanordnung übertragene Bewegung durch die Ausbildung der Kontaktflächen in der gewünschten Weise auf das Stellglied zu übertragen.The contact surface may cooperate with a counter contact surface arranged on the actuator. The interaction of the contact surface and the mating contact surface advantageously makes it possible to transfer the movement transmitted by the push element arrangement to the actuator in the desired manner by forming the contact surfaces.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung spricht das Betätigungselement ein mit der Kontaktfläche versehenes Bauteil unmittelbar an und verlagert dieses. Dies ermöglicht eine besonders einfache Bauweise sowie die Aufbringung hoher Betätigungskräfte auf die Kontaktfläche. Dementsprechend kann die Kontaktfläche auf die Gegenkontaktfläche auch große Kräfte übertragen. Hierdurch wird es möglich, dass über das Stellglied große Kräfte zur Arretierung der Feststellmittel ausgeübt werden.According to an advantageous embodiment of the invention, the actuator speaks directly to a provided with the contact surface component and moves it. This allows a particularly simple design and the application of high actuation forces on the contact surface. Accordingly, the contact surface on the mating contact surface can also transmit large forces. This makes it possible that over the actuator large forces are exerted to lock the locking means.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Betätigungselement auf ein erstes Bauteil der Schubelementanordnung einwirkt, welches durch Zwischenschaltung eines Federelementes ein mit der Kontaktfläche versehenes zweites Bauteil anspricht. Die Feder erlaubt das Aufbringen einer variablen Arretierkraft, die zudem genau einstellbar ist.A further embodiment of the invention provides that the actuating element acts on a first component of the thrust element arrangement, which responds by interposition of a spring element provided with the contact surface second component. The spring allows the application of a variable locking force, which is also precisely adjustable.
Gemäß einer weiteren Ausgestaltung der Erfindung werden die Kontaktfläche und die Gegenkontaktfläche von Keilflächen gebildet, welche eine Axialbewegung des zweiten Bauteils weichenartig in eine Bewegung des Stellgliedes mit zwei unterschiedlichen Richtungskomponenten umlenken. Diese Ausgestaltung ermöglicht in konstruktiv einfacher Form, beide Feststellmittel zugleich anzusprechen.According to a further embodiment of the invention, the contact surface and the mating contact surface of wedge surfaces are formed, which deflect an axial movement of the second component soft like a movement of the actuator with two different directional components. This embodiment allows in a structurally simple form to address both locking means at the same time.
Die Kontaktfläche kann zwischen einer Ruheposition, in der die Leuchte um beide Raumachsen schwenkbar ist, und einer Arbeitsposition, in welcher die Leuchte um die Raumachsen arretiert ist, verlagerbar sein. Zwischen diesen Extrempositionen der Kontaktfläche gibt es weitere Positionen der Kontaktfläche, in denen die Leuchte gegen einen mehr oder minder großen Widerstand um die Raumachsen herum schwenkbar ist.The contact surface can be between a rest position in which the lamp is pivotable about both spatial axes, and a working position in which locks the lamp to the spatial axes is, be relocatable. Between these extreme positions of the contact surface, there are other positions of the contact surface in which the lamp is pivotable against a more or less large resistance around the spatial axes.
Gemäß einer weiteren Ausgestaltung der Erfindung sind zwei Gehäuseschalen vorgesehen, zwischen denen im montierten Zustand ein Bewegungsspiel vorhanden ist. Eine der beiden Gehäuseschalen kann somit die Funktion des Stellgliedes übernehmen, wofür andernfalls ein gesondertes Bauteil notwendig wäre.According to a further embodiment of the invention, two housing shells are provided, between which in the mounted state, a movement play exists. One of the two housing shells can thus take over the function of the actuator, for which otherwise a separate component would be necessary.
So kann gemäß einer Ausgestaltung der Erfindung das Stellglied von einer Gehäuseschale gebildet sein, was eine einfache Bauweise ermöglicht und die Anzahl der Bauteile reduziert.Thus, according to one embodiment of the invention, the actuator may be formed by a housing shell, which allows a simple construction and reduces the number of components.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Kontaktfläche als Haltefläche für das Zusammenhalten der Gehäuseschalen ausgebildet. Die beiden Gehäuseschalen müssen auf diese Weise nicht durch Schrauben, Nieten od. dgl. Befestigungselemente miteinander verbunden sein, wodurch die Montage erleichtert wird.According to a further advantageous embodiment of the invention, the contact surface is designed as a holding surface for holding together the housing shells. The two housing shells od not in this way by screws, rivets. Like. Fasteners be connected to each other, whereby the assembly is facilitated.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Betätigungselement von einer Gewindeschraube gebildet ist. Dies ermöglicht die Verwendung handelsüblicher Teile für das Betätigungselement.A further embodiment of the invention provides that the actuating element is formed by a threaded screw. This allows the use of commercially available parts for the actuator.
Die Gewindeschraube kann mit einem Innengewinde in dem die Kontaktfläche aufweisenden Bauteil oder in dem ersten Bauteil der Schubelementeanordnung zusammenwirken. Mit dieser einfachen Anordnung ist es möglich, bei einfacher Bauweise eine lineare Verschiebung des Schubelements zu erreichen.The threaded screw can cooperate with an internal thread in the component having the contact surface or in the first component of the push element arrangement. With this simple arrangement, it is possible to achieve a linear displacement of the thrust element with a simple construction.

Eine Vorrichtung zur Befestigung einer Leuchte 13 wird in den Figuren insgesamt mit der Bezugsziffer 10 bezeichnet. In der nachfolgenden Figurenbeschreibung werden, sofern gleiche oder vergleichbare oder in ihrer Funktion ähnliche Teile oder Elemente beschrieben werden, der Übersichtlichkeit halber gleiche Bezugszeichen verwendet. Das gilt zur besseren Übersicht auch bei den unterschiedlichen Ausführungsbeispielen.A device for fixing a

Die Vorrichtung 10 weist eine erste Gehäuseschale 14 und eine zweite Gehäuseschale 15 auf, die im wesentlichen L-förmig ausgebildet sind. Gemäß den
Zur Ausbildung der ersten Drehverstellvorrichtung A ist an der Gehäuseschale 14 im Kopfbereich 41 ein Ringsteg 16 fest angeordnet, dessen Öffnung 18 von einem hohlen Gewindebolzen 17, welcher mit dem Stromschienen-Adapter 11 fest verbunden ist, durchgriffen wird. Auf diese Weise ist die Gehäuseschale 14 um die raumfeste Achse S1 drehbar auf dem Gewindebolzen 17 gelagert. Der Gewindebolzen 17 ist an dem Ringsteg 16 mittels eines Rings 22 gekontert, der auf dem Gewindebolzen 17 aufgeschraubt und durch z.B. eine Madenschraube M (siehe
Die Gehäuseschale 15 weist in einem dem Ringsteg 16 nahen Bereich Rippen 21a und 21b auf, welche mit der Außenumfangsfläche 23 des Ringes 22 zusammenwirken können und auf diese Weise eine Arretierung der Schwenkbewegung um die Achse S1 ermöglichen, wie weiter unten im Einzelnen beschrieben ist.The

Die innere Gehäuseschale 15 weist an ihrem zur Leuchte 13 hin gerichteten Ende Klemmelemente 35a auf, die als Zylindersegmente ausgebildet und mit konvexen zylindrischen Außenflächen 24a versehen sind. Diese wirken mit konkaven zylindrischen Flächen 25a der Flansche 26a, 26b kraftschlüssig zur Schwenkarretierung zusammen.The
In einem dem Stromschienen-Adapter 11 nahen Kopfbereich 41 der Vorrichtung 10 ist eine Schubelementanordnung E in dem Hohlraum H zwischen den Gehäuseschalen 14 und 15 angeordnet. Mittels einer Gewindeschraube 27, deren Außengewinde in ein Innengewinde 29 eines Schubbauteils 30 eingreift, kann letzteres in x-Richtung bewegt werden. Die Gewindeschraube 27 stützt sich mit ihrem Kopf in einer Sackausnehmung in dem Schalenteil 14 ab. Die Bewegung des Schubbauteils 30 bewirkt über eine Feder 31 mittelbar auch die Bewegung eines fliegend, also lose, auf der Gewindeschraube 27 gelagerten Keilelementes 32, dessen Kontaktfläche 33 mit einer an einem Vorsprung 39 der Gehäuseschale 15 angeordneten Gegenkontaktfläche 34 zusammenwirkt. Die Kontaktfläche 33 und die Gegenkontaktfläche 34 sind z.B. in einem 30°-Winkel zur Bewegungsrichtung x des Keilelementes 32 angeordnet. Die in x-Richtung wirkende Federkraft wird daher in in x- und y-Richtung wirkende Kraftkomponenten umgelenkt. Das Schubbauteil 30 und das Keilelement 32 sind von einer in
Die zwischen dem Schubelement 30 und dem Keilelement 32 angeordnete Druckfeder 31 bewirkt, dass mit zunehmenden Verstellweg des Schubbauteils 30 in Richtung x in Folge einer Betätigung der Gewindeschraube 27 eine größere Federkraft von der Feder 31 auf das Keilelement 32 übertragen wird. Die Kontaktfläche 33 spannt somit die Gehäuseschale 15 mit zunehmender Kraft gegen die Gehäuseschale 14. Die Arretierkraft kann somit variabel und genau eingestellt werden.The
Im weitgehend entspannten Zustand der Druckfeder 31 befindet sich das Schubelement 30 in einer Position, in der es an einem Anschlag 40 der Gehäuseschale 15 anliegt. Von der Feder 31 wird höchstens eine nur geringe Kraft auf das Keilelement 32 und damit auf die Gehäuseschale 14 ausgeübt. Die Gehäuseschalen 14, 15, die gemeinsam eine Art Tragarm 12 für die Leuchte 13 bilden, sind entgegen einem leichten Widerstand gemeinsam relativ zum Stromschienen-Adapter 11 um die Schwenkachse S1 schwenkbar. Infolge einer Drehbewegung des Tragarmes 12 relativ zu dem raumfest befindlichen Gewindebolzen 17, bewegen sich die Rippen 21a, 21b (
Ebenso ist der Strahler 13 entgegen einem leichten Widerstand relativ zum Tragarm 12 um die Schwenkachse S2 schwenkbar. Infolge einer Drehbewegung des Strahlers 13 um die Schwenkachse S2 relativ zu dem Tragarm 12 gleitet die dem Flansch 26a zugehörige Lagerfläche 25a entlang der entsprechenden zylindrischen Außenfläche 24a der Gehäuseschale 14. Gleichermaßen muss erwähnt werden, dass über das nur geringfügig gespannte Druckfederelement 31 und über das Keilelement 32 auch nur eine geringe Kraft in y-Richtung auf die Gehäuseschale 15 ausgeübt wird. Da der Strahler 13 über die Zapfen 38a, 38b fest mit der äußeren Schale 14 verbunden ist, und da bei Verlagerung der Gehäuseschale 15 in y-Richtung die Flächen 25a und 24a aufeinander zu bewegt werden, ist bei nur geringfügig gespanntem Federelement 31 die Klemmung zwischen den Flächen 24a und 25a nur relativ gering. Die Klemmkraft kann aber derartig hoch gewählt oder eingestellt werden, dass eine eingestellte Schwenkposition des Strahlers 13 um die Schwenkachse S2 aufgrund der Haftreibung beibehalten wird.Similarly, the
Ein Betätigen der Gewindeschraube 27 nach Ausrichtung des Strahlers 13 um die Achsen S1 und S2 bewirkt nun, dass das Schubbauteil 30 in x-Richtung bewegt wird wodurch die Federkraft der Feder 31 ansteigt. Das Keilelement 32 wird von der Feder 31 mit der Federkraft in x-Richtung gedrückt. Die in x-Richtung wirkende Kraft wird auf die Kontaktfläche 34 übertragen und weichenartig in x- und y-Richtung aufgeteilt, so dass sich die Gehäuseschale 15 relativ zu der Gehäuseschale 14 geringfügig sowohl in x- als auch in y-Richtung bewegt. Indem Seitenwände 20a und 20b der Gehäuseschale 14 Seitenwände 19a und 19b der Gehäuseschale 15 umgreifen (siehe
Die in x-Richtung wirkende Kraft bewirkt, dass die Stirnflächen 28a und 28b (
Durch Eindrehen der Gewindeschraube 27 können also gleichzeitig die Drehvorrichtungen A und B arretiert werden. Ein Lösen der Schwenkarretierung der beiden Achsen S1 und S2 ist auf einfache Weise durch Herausdrehen der Gewindeschraube 27 möglich, wodurch die Federkraft geringer wird. Dadurch hat die Gehäuseschale die Möglichkeit, sich in eine Position zu bewegen, in der beide Drehverstellvorrichtungen A und B gelöst, das heißt nicht arretiert, sind.By screwing in the threaded
Das in den Zeichnungen dargestellte Ausführungsbeispiel sieht die Befestigung der Leuchte 13 über die Vorrichtung 10 an einem Stromschienen-Adapter 11 vor, der somit, infolge seiner Festlegung an der gebäudefesten Stromschiene, die raumfeste Fläche im Sinne des Anspruches 1 darstellt. Gleichermaßen sind aber auch Ausführungsbeispiele von Vorrichtungen denkbar, bei denen die Leuchte 13 mittels der Vorrichtung 10 unmittelbar an einer raumfesten Fläche festgelegt werden kann.The embodiment shown in the drawings provides for the attachment of the
Bei dem Ausführungsbeispiel kann durch den Hohlraum H der Vorrichtung 10 auch eine Reihe von Spannungsversorgungsleitungen geführt werden. Die Vorrichtung 10 gemäß dem Ausführungsbeispiel dient somit sowohl der mechanischen Halterung der Leuchte 13 an der raumfesten Fläche als auch der Führung von elektrischen Zuleitungen für die Leuchte 13.In the embodiment, through the cavity H of the
Bei einem nicht dargestellten Ausführungsbeispiel der Erfindung ist es möglich, dass die Vorrichtung 10 nur der mechanischen Befestigung der Leuchte an der raumfesten Fläche dient.In an embodiment of the invention, not shown, it is possible that the
Des weiteren ist anzumerken, dass bei der in den Figuren dargestellten Ausführungsform das jeweilige Flächenpaar der Spannfläche und Gegenspannfläche, also das Paar der Flächen 28a, 23 der Drehverstellvorrichtung A und das Flächenpaar der Flächen 25a und 24a der Drehverstellvorrichtung B, als reine Klemm- oder Spannflächen ausgebildet ist. Alternativ kann im Bereich dieser Spannflächen bei einer nicht dargestellten Ausführung der Erfindung auch eine Verzahnung od. dgl. vorgesehen sein, die zu einem Formschluss zwischen diesen Flächen führen kann.Furthermore, it should be noted that in the embodiment shown in the figures, the respective surface pair of clamping surface and counter-clamping surface, ie the pair of
Schließlich kann im Bereich der Spannflächen auch ein reibungserhöhendes Element, beispielsweise ein Kunststoffelement oder ein Kunststoffbelag, angeordnet sein. Ein derartiges, reibungserhöhendes Element ist aber nicht in jedem Falle erforderlich.Finally, in the area of the clamping surfaces, a friction-increasing element, for example a plastic element or a plastic covering, may also be arranged. However, such a friction-enhancing element is not required in every case.
Im Folgenden soll nun das zweite Ausführungsbeispiel anhand der
Das zweite Ausführungsbeispiel umfasst eine gleichermaßen aus zwei Gehäuseschalenteilen 14, 15 jeweils im Wesentlichen L-förmiger Grundform (
Wie sich am Besten aus
Infolge einer Verlagerung des Bauteiles 32 in x-Richtung wird auch der Kopfbereich 41 des Gehäuseteiles 15 in x-Richtung verlagert. Wie sich am besten aus den
Infolge einer Betätigung der Gewindeschraube 27 wird somit infolge einer Verlagerung der Gehäuseschale 15 relativ zu der Gehäuseschale 14 der Ringkörper 22 beidseitig zwischen den beiden Gehäuseschalen 14, 15 eingespannt. Damit können gegenüber dem ersten Ausführungsbeispiel höhere Haltekräfte ausgeübt werden. Ein besonderer Vorteil ist dabei, dass die Außenumfangsfläche 23, 44 des Ringkörpers 20 auf die Innenumfangsflächen 43, 45 der beiden Spannbacken abgestimmt ist. Damit kann eine besonders sichere Klemmung erreicht werden.As a result of an actuation of the threaded
Der Fußbereich 42 der Vorrichtung 10 ist gegenüber dem ersten Ausführungsbeispiel der
Der sich über einen Winkelbereich von ca. 100° entlang einem Kreisbogen erstreckende Fußabschnitt 42 der Gehäuseschale 15 ruht auf einem Gegenmittel 46, welches nach Art einer Lagerschale gebildet ist, die auf ihrer Außenumfangsseite eine Gegenspannfläche 53 ausbildet. Das Gegenmittel 46 weist ein Lagerauge 48 auf, in dem ein Schwenkachsenelement 49 aufgenommen ist. Das Schwenkachsenelement 49 ist mit seinen beiden axialen Enden unmittelbar an der ersten Gehäuseschale 14 auf nicht dargestellte Weise befestigt.The over a angular range of about 100 ° along a circular arc extending
An dem bezüglich
Anzumerken ist; dass nicht die gesamte konkav ausgebildete Innenseite des Fußabschnittes 42 der Gehäuseschale 15 als Spannfläche fungiert, sondern lediglich ein sich über einen Winkelbereich von beispielsweise 40° oder 60° erstreckender Abschnitt, der die eigentliche Spannfläche 52 ausbildet. Die Spannfläche 52 und die gegenmittelseitige Gegenspannfläche 53 liegen über einen großflächigen Bereich aufeinander auf und ermöglichen die Erzielung großer Haltekräfte. Somit können auch schwere Strahler in der eingestellten Schwenkposition dauerhaft arretiert werden.It should be noted; that not the entire concave inside of the
Wird durch Betätigung des Betätigungselementes 27 das Bauteil 32 in x-Richtung bewegt, findet infolge der Keilflächen 33, 34 eine Verlagerung des Fußteils 42 des Stellgliedes 15 in y-Richtung statt. Dabei wird die Spannfläche 52 auf die Gegenspannfläche 53 gespannt, so dass es dort zu einer Verklemmung kommt. Das Gegenmittel 46 stützt sich dabei an der an der ersten Gehäuseschale 14 fest angeordneten Schwenkachse 49 ab, so dass in dem Fußbereich 42 eine Verspannung der Gehäuseschale 15 relativ zu der Gehäuseschale 14 erreicht wird.If the
Anzumerken ist, dass der Aufbau der Gehäuseschalenteile 14 und 15 des zweiten Ausführungsbeispieles mit dem des ersten Ausführungsbeispieles vergleichbar ist. Vorteilhaft ist, wenn an den Gehäuseschalen 14, 15 nicht dargestellte Versteifungsrippen oder Versteifungsstreben angeordnet sind, die sich innerhalb des Hohlraumes H der beiden Gehäuseschalenteile 14, 15 erstrecken.It should be noted that the structure of the
Ein besonderer Vorteil dieses Ausführungsbeispieles besteht darin, dass die aus den beiden Gehäuseschalenteilen 14, 15 und dem Gegenmittel 46 gebildete Baueinheit vormontierbar ist und insoweit handhabbar ist. Über die Befestigungsansätze 47 kann eine Befestigung der vormontierten Baueinheit mittels zweier Schrauben 56, von denen in
Lediglich zur Klarstellung sei angemerkt, dass die Befestigungsansätze 47 und die Befestigungsmittel 56 in
Der entscheidende Unterschied zwischen der Drehverstellvorrichtung B des zweiten Ausführungsbeispieles und der Drehverstellvorrichtung B des ersten Ausführungsbeispieles besteht darin, dass die innere und äußere Lagerschale vertauscht sind. Bei dem zweiten Ausführungsbeispiel ist die äußere Lagerschale dem Stellglied zugeordnet, wodurch größere Haltekräfte ausgeübt werden können. Dabei ist wesentlich, dass die Spannfläche die Gegenspannfläche übergreift.The crucial difference between the Drehverstellvorrichtung B of the second embodiment and the Drehverstellvorrichtung B of the first embodiment is that the inner and outer bearing shell are reversed. In the second embodiment, the outer bearing shell is associated with the actuator, whereby greater holding forces can be exercised. It is essential that the clamping surface overlaps the counter-clamping surface.
Wie sich aus der vorstehenden Beschreibung ergibt, ist bei dem zweiten Ausführungsbeispiel ein Zusammenbau der Vorrichtung 10 wie folgt möglich:As apparent from the foregoing description, in the second embodiment, assembly of the
An der Gehäuseschale 14 ist bereits das später noch leuchtenseitig anzubringende Gegenmittel 46 festgelegt. Die Gehäuseschale 14 kann nun, schräg geneigt, zu der Gehäuseschale 14 auf diese zubewegt werden, wobei der Steckansatz 51 in den Zwischenraum Z zwischen Gegenspannfläche 53 und Gehäuseschale 14 eingeführt wird. Nachfolgend kann die Gehäuseschale 15 im Uhrzeigersinn relativ zu der Gehäuseschale 14 derart verschwenkt werden, bis die beiden Gehäuseschalen 14 aneinander anliegen. Die Gegenkontaktfläche 34 konnte dabei infolge der Schwenkbewegung in x-Richtung hinter die Kontaktfläche 33 gelangen. Wird nun die Gewindeschraube 27 betätigt und das Bauteil 32 in x-Richtung bewegt, kommt es zu einem Kontakt der Kontaktfläche 33 mit der Gegenkontaktfläche 34. Damit ist die Gehäuseschale 15 an zwei Punkten, nämlich im Bereich der Kontakt- und der Gegenkontaktfläche 33/34 und im Bereich der Spannfläche 52 und der Gegenspannfläche 53 an der Gehäuseschale 14 gehalten. Damit ist eine unverlierbare Anordnung der Gehäuseschalenteile 14, 15 getroffen. Die Gehäuseschale 15 kann aber in diesem vormontierten Zustand noch mit Bewegungsspiel relativ zu der Gehäuseschale 14 verlagert werden. Hierzu muss die Gewindeschraube 27 lediglich weiter betätigt werden. Dies geschieht vornehmlich aber erst dann, wenn der Strahler 13 an der Vorrichtung 10 angebunden ist.On the
Ein Lösen des Betätigungselementes 27 durch Drehung in der entgegengesetzten Richtung kann eine Schwenkarretierung des Strahlers 13 um die beiden Raumachsen S1 und S2 in der zuvor beschriebenen Weise aufheben. Dabei bewegt sich das in einer Kulissenbahn geführte Bauteil 32 bei Drehung des Betätigungselementes 27 um dessen Längsachse bezüglich
Nachdem die Gewindestange 27 bei der Montage der Vorrichtung 10 durch die Gehäuseschale 14 eingesteckt ist, kann die Sicherungsmutter 54 von der bezüglich
Vorteilhafterweise wird die Sicherungsmutter 54 mit einem Abstand von beispielsweise ca. 0,5 mm zu der Innenseite 55 festgelegt, so dass sich das Betätigungselement 27 aufgrund des Bewegungsspieles problemlos betätigen lässt.Advantageously, the
Alternativ zu der zuvor beschriebenen Montage der Vorrichtung 10 zu einer handhabbaren Einheit kann auch vorgesehen sein, dass zunächst die Gehäuseschale 14 mit dem Gegenmittel 46 an dem Strahler 13 befestigt wird. Anschließend können elektrische Zuleitungen in den Hohlraum H der Gehäuseschale 14 eingelegt und mit dem Strahler 13 verbunden werden. Erst zuletzt kann die Gehäuseschale 15 an der Gehäuseschale 14 festgelegt werden, wobei der zuvor erwähnte Einschwenkvorgang der Gehäuseschale 15 relativ zu der Gehäuseschale 14 nach dem Einstecken des Fortsatzes 51 in den Zwischenraum Z gleichermaßen bewerkstelligbar ist.As an alternative to the above-described assembly of the
