Description

Die Erfindung betrifft eine Lichtschrankenhalterung, wie sie insbesondere bei Durchfahrtslichtschranken für automatische Garagentore eingesetzt werden.The invention relates to a light barrier holder, as they are used in particular for through-beam sensors for automatic garage doors.

Derartige Durchfahrtslichtschranken werden als Sensoren zur Absicherung gefahrbringender Bewegungen an Toren eingesetzt. Üblicherweise bestehen derartige Durchfahrtslichtschranken aus einem Lichtschrankensender und einem Lichtschrankenempfänger, die beispielsweise beidseitig an das Garagentor angeordnet sind, um so die Durchfahrt eines Fahrzeuges festzustellen. Derartige Lichtschranken werden üblicherweise mittels Montagewinkel installiert. Sie können aber auch in Torpfosten, Unterputzdosen oder in auf den Putz aufgesetzte Dosen montiert werden.Such through-beam sensors are used as sensors for securing dangerous movements on gates. Usually, such through-beam sensors consist of a light barrier transmitter and a light barrier receiver, which are arranged for example on both sides of the garage door, so as to determine the passage of a vehicle. Such photocells are usually installed by means of mounting brackets. But they can also be mounted in goal posts, flush-mounted boxes or placed on the plaster cans.

Bei der Montage der jeweiligen Teile der Lichtschranke, das heißt des Senders und des Empfänger, auf gegenüberliegenden Seiten erweist es sich häufig als schwierig, die jeweiligen Teile genau aufeinander auszurichten.When mounting the respective parts of the light barrier, that is, the transmitter and the receiver, on opposite sides, it often proves difficult to align the respective parts exactly to each other.

Aufgabe der Erfindung ist es daher, eine Lichtschrankenhalterung bereit zu stellen, die eine einfache Justierung der Lichtschrankenteile bei der Montage ermöglicht.The object of the invention is therefore to provide a light barrier holder, which allows easy adjustment of the light curtain parts during assembly.

Erfindungsgemäße wird diese Aufgabe durch die Kombination der Merkmale des Anspruchs 1 gelöst. Demnach besteht die erfindungsgemäße Lichtschrankenhalterung aus einem Aufnahmegehäuse zur Aufnahme eines Teiles der Lichtschranke, beispielsweise eines Senders oder Empfängers mit einer Öffnung, durch die die Strahlen der Lichtschranke treten können. Erfindungsgemäß ist die Oberfläche des Gehäuses im Bereich der Öffnung kalottenförmig gewölbt, wobei im Bereich der Öffnung ein rohrförmiger Ansatz am Gehäuse ansetzt, der durch entsprechende Öffnungen von jeweils eine entsprechende kalottenförmige Wölbung aufweisenden Montageelementen steckbar ist und durch ein Sicherungselement festlegbar ist. Unter Ausnutzung dieser kalottenförmigen Geometrie ist eine Einstellung und Einrichtung von Sender und Empfänger in einfacher Weise zueinander möglich. Vor Sichern mittels des Sicherungselements oder nach Lösen des Sicherungselementes kann das Aufnahmegehäuse aufgrund der kalottenförmigen Geometrie gegenüber den Montageelementen verschwenkt werden. Nach Erreichen der gewünschten Position kann dann die Position fixiert werden.According to the invention, this object is achieved by the combination of the features of claim 1. Accordingly, the light barrier holder according to the invention consists of a receiving housing for receiving a portion of the light barrier, such as a transmitter or receiver with an opening through which the beams of the light barrier can pass. According to the invention, the surface of the housing in the region of the opening is dome-shaped, wherein in the region of the opening attaches a tubular projection on the housing, which is pluggable through corresponding openings of each corresponding dome-shaped mounting elements mounting elements and can be fixed by a fuse element. Taking advantage of this dome-shaped geometry adjustment and setup of transmitter and receiver in a simple manner to each other possible. Before securing by means of the securing element or after releasing the securing element, the receiving housing can be pivoted due to the dome-shaped geometry relative to the mounting elements. After reaching the desired position, the position can then be fixed.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the subsequent claims to the main claim.

Demnach kann der rohrförmige Ansatz ein Außengewinde aufweisen. Das Sicherungselement ist als Befestigungsmutter ausgebildet, die auf das Außengewinde des rohrförmigen Ansatzes aufschraubbar ist. Hierdurch ist ein leichtes Montieren bzw. Lösen der Verbindung möglich.Accordingly, the tubular projection may have an external thread. The securing element is designed as a fastening nut which can be screwed onto the external thread of the tubular extension. As a result, an easy mounting or disconnecting the connection is possible.

Vorteilhaft bestehen sämtliche Einzelteile aus Kunststoff.Advantageously, all items are made of plastic.

Die Montageelemente bestehen aus scheiben- oder plattenförmigen Elementen. Vorteilhaft sind zwei Montageelemente vorhanden, die ganz besonders vorteilhaft ineinander steckbar und miteinander verclipsbar sind, so daß eine Montage in einer entsprechenden Ausnahmeöffnung - beispielsweise eines Montagewinkels oder eines Torpfostens oder dergleichen - möglich ist. Bei dieser Ausführung werden die scheiben- bzw. plattenförmigen Elemente beidseitig der Montageöffnung des Montagewinkels bzw. Torpfostens aufgesetzt und miteinander verclipst. In diese vormontierten Montageelemente wird dann das entsprechende Aufnahmegehäuse eingeschoben und über das Sicherungselement festgelegt.The mounting elements consist of disc or plate-shaped elements. Advantageously, two mounting elements are present, which are very particularly advantageous plugged into each other and clipped together, so that an assembly in one appropriate exception opening - for example, a mounting bracket or a goal post or the like - is possible. In this embodiment, the disc or plate-shaped elements are placed on both sides of the mounting hole of the mounting bracket or goal post and clipped together. In this preassembled mounting elements, the corresponding receiving housing is then inserted and fixed on the fuse element.

Besonders vorteilhaft sind die Montageelemente beidseitig einer langgestreckten Ausnehmung beispielsweise eines Montagewinkels angeordnet. Hierdurch ist nicht nur ein Verschwenken der Lichtschrankenhalterung zur Einstellung und Ausrichtung von Sender und Empfänger zueinander sondern auch ein Längsverschieben entlang der langgestreckten Ausnehmung möglich.Particularly advantageously, the mounting elements are arranged on both sides of an elongate recess, for example a mounting bracket. This not only a pivoting of the photocell holder for adjusting and alignment of transmitter and receiver to each other but also a longitudinal displacement along the elongated recess is possible.

Anstelle des Vorsehens von separaten Montageelementen, kann das Montageelement mit der an die kalottenförmige Oberfläche des Ausnahmegehäuses angepassten kalottenförmigen Wölbung Teil eines ansonsten bereits handelsüblichen Montagegehäuses sein. Das Montageelement kann alternativ auch mit angepaßter kalottenförmiger Wölbung mit entsprechender Ausnehmung als Teil eines Torpfeilers oder eines anderen Bauelementes ausgebildet sein.Instead of providing separate mounting elements, the mounting element with the dome-shaped curvature adapted to the dome-shaped surface of the exception housing can be part of an otherwise already commercially available mounting housing. The mounting member may alternatively be formed with adapted dome-shaped curvature with a corresponding recess as part of a Torpfeilers or other component.

In Figur 1 ist schematisch der Innenraum einer Garage gezeigt, in welcher ein automatisches Sektional-Garagentor 10, das in Laufschienen 12 geführt ist, über einen Garagentorantrieb 14 geöffnet und geschlossen werden kann. Derartige Systeme sind allgemein bekannt, so daß hier auf eine detaillierte Darstellung verzichtet werden kann. Das Sektional-Garagentor 10 ist hier in geschlossener Position gezeigt. Neben dem Sektional-Garagentor 10 sind mittels zweier Montagewinkel 16 identischen Aufbaus zwei Teile einer Lichtschranke, nämlich ein Lichtschrankensender 18 und ein Lichtschrankenempfänger 20 angeordnet. Sowohl der Lichtschrankensender 18 wie auch der Lichtschrankenempfänger 20 sind über Leitungen 22 mit dem Garagentorantrieb 14 verbunden, so daß entsprechende Signale beim Erfassen eines Gegenstandes, beispielsweise eines Kraftwagens 5, an den Garagentorantrieb gemeldet werden können.In Figure 1, the interior of a garage is shown schematically, in which an automatic sectional garage door 10, which is guided in rails 12, can be opened and closed by a garage door drive 14. Such systems are well known, so that can be dispensed with a detailed presentation here. The sectional garage door 10 is shown here in the closed position. In addition to the sectional garage door 10 two parts of a light barrier, namely a light barrier transmitter 18 and a light barrier receiver 20 are arranged by means of two mounting bracket 16 identical structure. Both the light barrier transmitter 18 and the light barrier receiver 20 are connected via lines 22 to the garage door drive 14, so that corresponding signals when detecting an object, such as a motor vehicle 5, can be reported to the garage door drive.

In der Figur 2 ist zunächst der Aufbau des Montagewinkels 16 im einzelnen dargestellt. Der Montagewinkel 16 besteht aus einem abgekanteten Blechzuschnitt mit zwei Stegen 24 und 26. Der von beiden Stegen 24 und 26 eingeschlossene Winkel beträgt ca. 90°, so daß sich insgesamt die Form eines L ergibt. Der Montagewinkel 16 weist eine langgestreckte rechteckige Öffnung 32 auf, in welche die Lichtschrankenhalterungen 50 für den Sender bzw. Empfänger der Lichtschranke aufgenommen und durch entsprechendes Verschieben der Lichtschrankenhalterung 50 auch in der Länge positioniert werden kann.In the figure 2, first, the structure of the mounting bracket 16 is shown in detail. The mounting bracket 16 consists of a folded sheet metal blank with two webs 24 and 26. The included by two webs 24 and 26 angle is about 90 °, so that overall the shape of an L results. The mounting bracket 16 has an elongated rectangular opening 32, in which the light barrier holders 50 can be added to the transmitter or receiver of the light barrier and positioned by appropriate displacement of the light barrier holder 50 in length.

Der Aufbau der Lichtschrankenhalterung 50 ergibt sich insbesondere aus der explosionsartigen Darstellung in Figur 2 b. Die Lichtschrankenhalterung 50 besteht zunächst aus einem Gehäuse 52, in welchem jeweils Teile der Lichtschranke, beispielsweise eines Senders oder Empfängers in hier nicht näher dargestellter Art und Weise eingesetzt sind. Die Strahlen der Lichtschranken treten durch eine Öffnung 54 aus. Die Oberfläche 56 des Gehäuses im Bereich der Öffnung 54 ist kalottenförmig gewölbt und im Bereich der Öffnung ist ein rohrförmiger Ansatz 58 am Gehäuse angesetzt. Der rohrförmige Ansatz 58 weist ein Außengewinde auf.The structure of the light barrier holder 50 results in particular from the exploded view in Figure 2 b. The light barrier holder 50 initially consists of a housing 52, in which parts of the light barrier, for example, a transmitter or receiver are used in a manner not shown here in detail. The beams of the light barriers exit through an opening 54. The surface 56 of the housing in the region of the opening 54 is dome-shaped curved and in the region of the opening, a tubular extension 58 is attached to the housing. The tubular extension 58 has an external thread.

An Figur 2 b sind beidseitig der langgestreckten Ausnehmung 32 des Montagewinkels 16 Montageelemente 60 und 62 angeordnet. Beide Montageelemente 60 und 62 weisen jeweils vergleichsweise zum Außendurchmesser des rohrförmigen Ansatzes 58 große Öffnungen 64 und 66 auf. Die jeweiligen Montageelemente sind teilweise oder vollständig ebenfalls kalottenförmig geformt, wobei die Oberflächenwölbung der kalottenförmigen Oberfläche 56 des Aufnahmegehäuses 52 entspricht. Die beiden Montageelemente 60 und 62 sind in der hier dargestellten Ausführungsvariante derart ausgebildet, dass sie nach beidseitigem Aufsetzen auf den Montagewinkel 16 im Bereich der langgestreckten Ausnehmung 32 miteinander verclipsbar sind.On Figure 2 b 16 mounting elements 60 and 62 are arranged on both sides of the elongated recess 32 of the mounting bracket. Both mounting elements 60 and 62 each have comparatively to the outer diameter of the tubular extension 58 large openings 64 and 66. The respective mounting elements are partially or completely also dome-shaped, wherein the surface curvature of the dome-shaped surface 56 of the receiving housing 52 corresponds. The two mounting elements 60 and 62 are formed in the embodiment shown here in such a way that they are clipped together after two-sided placement on the mounting bracket 16 in the region of the elongated recess 32.

Das Montageelement 60 ist als Kunststoffspritzgussteil ausgebildet, das im wesentlichen ringförmig gestaltet ist, wobei der Ring an seiner inneren und äußeren Oberfläche jeweils die zuvor beschriebene Kalottenform aufweist. Der Außendurchmesser des Rings 60 entspricht im wesentlichen der Breite der Ausnehmung 32 des Montagewinkels 16. Am ringförmigen Hauptteil des Montageelementes 60 sind zwei Ansätze 68 angeformt, die die Ausnehmung 32 übergreifen und das Montageelement 60 einseitig an der Schiene 60 abstützen. Seitlich sind am Montageelement 60 zwei kleine Ausnehmungen 70 vorgenommen, die in entsprechende Vorsprünge im Montageelement 62 eingreifen können und dadurch ein verclipsen bzw. festklemmen der beiden Montageelemente 60 und 62 ermöglichen. Nach entsprechender Montage der Montageelemente 60 und 62 und im gegenseitigen Verclipsen bzw. Festklemmen können diese entlang der langgestreckten Ausnehmung 32 im Montagewinkel 16 verschoben werden, so daß hier eine Längsverschiebung der Lichtschrankenhalterung 50 und damit auch der Lichtschrankenteile ermöglicht wird.The mounting member 60 is formed as a plastic injection molded part, which is designed substantially annular, wherein the ring has on its inner and outer surfaces each have the previously described Kalottenform. The outer diameter of the ring 60 corresponds substantially to the width of the recess 32 of the mounting bracket 16. On the annular main part of the mounting member 60 two lugs 68 are formed, which engage over the recess 32 and the mounting member 60 are supported on one side of the rail 60. On the side of the mounting element 60 two small recesses 70 are made, which can engage in corresponding projections in the mounting member 62 and thereby verclipsen or clamp the two mounting members 60 and 62 allow. After appropriate mounting of the mounting members 60 and 62 and mutual clipping or clamping they can be moved along the elongated recess 32 in the mounting bracket 16 so that a longitudinal displacement of the light barrier holder 50 and thus also the light cabinet parts is made possible.

Nach entsprechender Vormontage der Montageelemente 60 und 62 an das Aufnahmegehäuse 50 mit seinem rohrförmigen Ansatz 58 durch die Öffnungen 64 und 66 der Montageelemente 60 und 62 gesteckt werden und nach entsprechender Positionierung durch Verschwenken mittels eines als Befestigungsmutter 72 ausgebildetes Sicherungselements durch Aufschrauben derselben fixiert werden. Auch die Sicherungsmutter 72 ist so ausgeformt, dass sie sich der kalottenförmigen Wölbung des Sicherungselemente 62 anpasst. Durch Festziehen der Befestigungsmutter 72 kann die Lichtschrankenhalterung in der gewünschten Position fixiert werden.After appropriate pre-assembly of the mounting members 60 and 62 are inserted into the receiving housing 50 with its tubular extension 58 through the openings 64 and 66 of the mounting members 60 and 62 and after appropriate positioning by pivoting by means of a trained as a fastening nut 72 securing element by screwing them are fixed. Also the Lock nut 72 is formed so that it adapts to the dome-shaped curvature of the securing elements 62. By tightening the fastening nut 72, the light barrier holder can be fixed in the desired position.

In den Figuren 3 a und 3 b ist die Lichtschrankenhalterung jeweils in einer anderen perspektivischen Darstellung im montierten Zustand gezeigt.In Figures 3 a and 3 b, the light barrier holder is shown in each case in a different perspective view in the assembled state.

Die hier dargestellte Ausführungsvariante zeigt, dass zwischen den beiden Montageelementen 60 und 62 der Montagewinkel 16 angeordnet ist. Durch eine entsprechende Handhabung kann eine abstandsveränderte Festlegung längs der rechtekkigen Öffnung 32 im Montagewinkel 16 sowie eine Ausrichtung der optischen Achse "Sender - Empfänger" mit Rundum-Schwenkmöglichkeit des kalottenförmig ausgebildeten Gehäuses erfolgen.The embodiment variant shown here shows that the mounting bracket 16 is arranged between the two mounting elements 60 and 62. By appropriate handling, a distance-changing attachment can be made along the rectangular opening 32 in the mounting bracket 16 as well as alignment of the optical axis "transmitter - receiver" with all-round pivoting possibility of the dome-shaped housing.

In den hier dargestellten Ausführungsbeispielen nicht gezeigt ist die Möglichkeit, dass das Lichtschrankengehäuse 50 in einer handelsüblichen Unterputzdose eingebaut wird. Hier wird die Lichtschranke mit einer glattflächigen Abschlussblende verklemmt, die auf die Unterputzdose montiert ist. Möglich wäre auch die Unterbringung der Lichtschranke in einem Torpfeiler, der beispielsweise bei Hofschiebetoren oder Hofdrehtoren zum Einsatz kommen kann. In entsprechenden Bohrungen kann die Lichtschranke bei einer derartigen Einbauvariante unmittelbar in den Pfeiler unter Ausnutzung der Schwenkmöglichkeit durch die Kalottengeometrie montiert werden.Not shown in the embodiments shown here is the possibility that the light barrier housing 50 is installed in a commercially available flush-mounted box. Here, the light barrier is jammed with a smooth-surfaced cover, which is mounted on the flush-mounted box. It would also be possible to accommodate the light barrier in a Torpfeiler that can be used for example in Hofschiebetoren or Hofdrehtoren. In appropriate holes, the light barrier can be mounted in such a mounting variant directly into the pillar by utilizing the possibility of pivoting through the Kalottengeometrie.

Sofern die Montage der Lichtschranke in Verbindung mit einem Montagewinkel oder Unterputz in einer Wand oder innerhalb eines Torpfeilers nicht in Frage kommt, kann eine weitere Aufputzmontageart in unterschiedlichsten Gehäusen vorgenommen werden. Durch diese Gehäuse ist weiterhin ein zusätzlicher Feuchtigkeitsschutz gegeben, welcher für die Montage im Außenbereich erforderlich ist.If the mounting of the light barrier in connection with a mounting bracket or flush-mounted in a wall or within a Torpfeilers is out of the question, another Aufputzmontageart can be made in a variety of housings. Through these housing, an additional moisture protection is given, which is required for outdoor installation.
