Description

Die Erfindung betrifft einen Türkontakt als Überbrückungskontakt mit einem Gehäuse und mit zumindest zwei in dem Gehäuse angeordneten elektrischen Kontaktelementen, wobei zumindest je zwei der Kontaktelemente durch eine einem ersten Türflügel zuordenbare Kontaktbrücke unter Schließung eines elektrischen Stromkreises überbrückbar sind.The invention relates to a door contact as a bridging contact with a housing and with at least two arranged in the housing electrical contact elements, wherein at least two of the contact elements can be bridged by a first door wing assignable contact bridge to close an electrical circuit.

Derartige Überbrückungskontakte werden bei Türen verwendet, um das Schließen bzw. Öffnen der Tür, z.B. einer Aufzugstür, sicher überwachen zu können. So können z.B. erst bei geschlossener Tür und damit bei überbrücktem Türkontakt bzw. geschlossenem Stromkreis bestimmte Einrichtungen aktiviert werden, z.B. ein Aufzug in Gang gesetzt werden. Der Kontakt wird hierbei zumeist benachbart der Tür angeordnet und an der Türzarge oder einem neben der Tür angeordneten Wandbereich befestigt, wobei die Kontaktbrücke an der Tür angeordnet und mit dieser bewegbar ist.Such bridging contacts are used on doors to lock the door, e.g. an elevator door to be able to monitor safely. Thus, e.g. certain devices are activated only when the door is closed and thus when the door contact or closed circuit is bridged, e.g. an elevator will be set in motion. The contact is in this case usually arranged adjacent to the door and fastened to the door frame or a wall region arranged next to the door, the contact bridge being arranged on the door and being movable therewith.

Bei zweiflügeligen Türen ist es dementsprechend zur Überwachung der Schließstellung der Tür notwendig, jedem der Türflügel einen Türkontakt an der Türzarge bzw. einem benachbarten Wandbereich zuzuordnen. Für bestimmte Anwendungsfälle ist es dann erforderlich, die beiden Türkontakte mittels einer Drahtbrücke über die jeweiligen Kontaktelemente kurzzuschließen. Des weiteren müssen die beiden Türkontakte jeweils in Bezug auf die korrespondierenden Überbrückungskontakte ausgerichtet werden, damit die Stifte der Überbrückungskontakte exakt mit den korrespondierenden Kontaktelementen zur Anlage kommen und Verkantungen der Kontaktelemente, ein Abrutschen der Stifte von den Kontaktelementen oder andere Fehlfunktionen vermieden werden. Der Aufwand bei der Herstellung, aber insbesondere auch bei der Montage herkömmlicher Türkontakte ist somit vergleichsweise hoch.Accordingly, in the case of double-leaf doors, it is necessary for monitoring the closed position of the door to associate each door leaf with a door contact on the door frame or on an adjacent wall area. For certain applications, it is then necessary to short-circuit the two door contacts by means of a wire bridge over the respective contact elements. Furthermore, the two door contacts must each be aligned with respect to the corresponding bridging contacts, so that the pins of the bridging contacts come exactly with the corresponding contact elements to the plant and tilting of the contact elements, slipping of the pins of the contact elements or other malfunctions are avoided. The effort in the production, but especially in the assembly of conventional door contacts is thus relatively high.

Die GB 294025 beschreibt einen Schalter eines Aufzuges, der an der Aufzugskabine angeordnet ist, welcher zwei schwenkbar gelagerte Kontaktelemente aufweist und die Verfahrung der Aufzugskabine in ihre Sollposition anzeigt.The GB 294025 describes a switch of a lift, which is arranged on the elevator car is, which has two pivotally mounted contact elements and indicates the passage of the elevator car in its desired position.

Der Erfindung liegt die Aufgabe zugrunde, einen Türkontakt zu schaffen, der einfach herstellbar und leicht montierbar ist.The invention has for its object to provide a door contact that is easy to manufacture and easy to install.

Die Aufgabe wird durch einen Türkontakt gelöst, bei welchem in dem Gehäuse zumindest eine weitere Kontaktelementanordnung mit zumindest einem Paar von elektrischen Kontaktelementen vorgesehen ist, die durch eine weitere Kontaktbrücke überbrückbar sind, welche einem weiteren Türflügel zuordenbar ist, wobei beide Kontaktelementanordnungen derart angeordnet sind, dass sie von an verschiedenen Türflügeln einer mehrflügeligen Tür angeordneten Kontaktbrücken überbrückbar sind. Zur Überwachung der Schließstellung einer mehrflügeligen Tür ist somit nur noch ein einziger Türkontakt zwischen beiden Türflügeln in deren Schließstellung zu montieren. Des weiteren ist es auch nicht mehr erforderlich, zwei unabhängige Türkontakte zu den jeweiligen Kontaktbrücken hin auszurichten, da durch die erfindungsgemäße Anordnung der den unterschiedlichen Kontaktbrücken zugeordneten Kontaktelemente in einem Gehäuse bei der Ausrichtung des Gehäuses gleichzeitig eine Ausrichtung der Kontaktelemente beider Kontaktelementanordnungen zu den korrespondierenden Kontaktbrücken erfolgt. Ist es des weiteren erforderlich, die den unterschiedlichen Kontaktbrücken zugeordneten Kontaktelemente miteinander zu überbrücken, so können diese Arbeiten bereits vor der Montage des Türkontaktes erfolgen, da in dem Gehäuse die den beiden Kontaktbrücken zugeordneten Kontaktelemente bereits vereinigt sind. Die Überbrückung kann gegebenenfalls auch bereits werksseitig erfolgen. Der Montageaufwand des erfindungsgemäßen Türkontaktes ist somit erheblich vereinfacht.The object is achieved by a door contact, wherein in the housing at least one further contact element arrangement is provided with at least one pair of electrical contact elements, which can be bridged by a further contact bridge which can be assigned to a further door leaf, wherein both contact element arrangements are arranged such that they can be bridged by arranged on different doors of a multi-leaf door contact bridges. To monitor the closed position of a multi-leaf door thus only a single door contact between the two leaves is to be mounted in its closed position. Furthermore, it is also no longer necessary to align two independent door contacts to the respective contact bridges, since at the same time aligning the contact elements of both contact element arrangements to the corresponding contact bridges by the inventive arrangement of the different contact bridges associated contact elements in a housing in the orientation of the housing , If it is further necessary to bridge the contact bridges associated with the different contact elements with each other, so these work can be done before the installation of the door contact, as in the housing, the two contact bridges associated contact elements are already united. If necessary, the bridging can already be done at the factory. The installation effort of the door contact according to the invention is thus considerably simplified.

Der erfindungsgemäße Türkontakt ist sowohl bei Schiebetüren als auch bei Schwenktüren bei entsprechender Anordnung der Kontaktelemente einsetzbar. Unter einer Tür seien hierbei auch Klappen oder andere plattenförmige Verschlußteile für Öffnung verstanden.The door contact according to the invention can be used both with sliding doors and swing doors with a corresponding arrangement of the contact elements. Under a door are here too Flaps or other plate-shaped closure members for opening understood.

Ist der erfindungsgemäße Türkontakt zur Überwachung der Schließstellung einer zweiflügeligen Schiebetür wie z.B. einer zweiflügeligen Aufzugstür vorgesehen, so sind vorzugsweise die von den beiden unabhängigen Kontaktbrücken jeweils überbrückbaren Kontaktelemente auf gegenüberliegenden Seiten des Gehäuses angeordnet und durch aus einander entgegengesetzten Richtungen heranführbare Kontaktbrücken überbrückbar. Der Türkontakt weist somit eine bezüglich der Schieberichtung der Türen senkrecht stehende Symmetrieebene auf.Is the door contact according to the invention for monitoring the closed position of a double-leaf sliding door such. provided a two-leaf elevator door, the contact elements bridged by the two independent contact bridges are preferably arranged on opposite sides of the housing and can be bridged by contact bridges which can be brought in from opposite directions. The door contact thus has a relative to the sliding direction of the doors perpendicular symmetry plane.

Bei zweiflügeligen Schwenktüren können die Kontaktelemente nebeneinander bzw. gleichsinnig orientiert parallel zueinander angeordnet sein, so daß beide an den Schwenkflügeln angeordnete Kontaktbrücken in gleicher Richtung auf den Türkontakt zugeschwenkt mit den zugeordneten Kontaktelementen zur Anlage bringbar sind.In two-leaf swing doors, the contact elements can be arranged side by side or in the same direction oriented parallel to each other, so that both arranged on the pivot wings contact bridges swung in the same direction on the door contact with the associated contact elements to the system can be brought.

Die Kontaktelementanordnung des erfindungsgemäßen Türkontaktes kann natürlich auch andere Geometrien aufweisen und an andere Schließstellungen der mehrflügeligen, insbesondere zweiflügeligen, Tür angepasst sein. So können beispielsweise die Kontaktelemente bzw. die Längsachsen der Federelemente einen Winkel von beipielsweise 90° einschließen wenn die Türflügel bei geschlossener Tür einen solchen Winkel einschliessen. Schließt die an den Türen angeordnete Kontaktbrücke einen Winkel zu dem zugeordneten Türblatt auf, so kann die Längserstreckung der Kontaktelemente bzw. der Federelemente auch einen hiervon unterschiedlichen geeigneten Winkel zu der Heranführungsrichtung des Türblattes aufweisen.Of course, the contact element arrangement of the door contact according to the invention can also have other geometries and be adapted to other closed positions of the multi-leaf, in particular double-leaf, door. For example, the contact elements or the longitudinal axes of the spring elements can include an angle of, for example, 90 ° when the door leaves enclose such an angle when the door is closed. If the contact bridge disposed on the doors forms an angle with respect to the associated door leaf, then the longitudinal extent of the contact elements or of the spring elements can also have a different angle to the pre-insertion direction of the door leaf.

Die Kontaktelemente sind vorzugsweise federnd gelagert, wozu Blattfedern, Wendel- bzw. Spiralfedern oder vorzugsweise Kegelstumpffedern verwendet werden, wobei die Wendel- bzw. Spiralfedern oder Kegelstumpffedern unter Zug, vorzugsweise unter Druck belastbar sein können. Die Federelemente, insbesondere die Kegelstumpffedern können Teil des jeweiligen Stromkreises sein.The contact elements are preferably spring-mounted, for which purpose leaf springs, helical or spiral springs or preferably truncated cones are used, wherein the helical or spiral springs or truncated cones under train, preferably under pressure can be loaded. The spring elements, in particular the truncated cone springs can be part of the respective circuit.

Nach einer vorteilhaften Ausführungsform sind die Kontaktelemente der ersten Kontaktelementanordnung mit den Kontaktelementen der zweiten Kontaktelementanordnung elektrisch leitend verbindbar oder verbunden. Hierzu kann ein Bereich des Gehäuses zur Aufnahme bzw. Durchführung eines Überbrückungsgliedes ausgebildet sein, ggf. durch Anordnung eines wahlweise demontierbaren Gehäusebereichs oder einem demontierbaren Trennelement, das mit Sollbruchstellen oder lösbaren Befestigungsbereichen ausgestattet sein kann, wobei das Überbrückungsglied beipielsweise als Draht oder als plättchenförmiges Bauteil mit Kontaktpolen oder auf andere geeignete Weise ausgeführt sein kann. Der das Überbrückungsglied aufnehmende Gehäusebereich kann derart ausgebildet sein, daß das Überbrückungsglied kraft- und/oder formschlüssig an dem Gehäuse festlegbar ist. Hierdurch liegen bei gleichzeitiger Überbrükkung der Kontaktelementanordnungen durch die an den Türen vorgesehenen Kontaktbrücken sämtliche Kontaktelemente des Türkontaktes auf gleichem Potential, wobei die beiden o.g. Kontaktelemente der ersten und zweiten Anordnung mit weiterführenden elektrischen Leitungen stromführend verbunden sein können.According to an advantageous embodiment, the contact elements of the first contact element arrangement are electrically conductively connected or connected to the contact elements of the second contact element arrangement. For this purpose, an area of the housing for receiving or carrying a bridging member may be formed, optionally by arranging an optionally removable housing portion or a removable partition member which may be equipped with predetermined breaking points or detachable mounting portions, wherein the bridging member with example as a wire or as a platelet-shaped component Contact poles or may be carried out in any other suitable manner. The housing portion accommodating the bridging member may be designed in such a way that the bridging member can be fastened non-positively and / or positively to the housing. As a result, all contact elements of the door contact at the same potential are at the same time bridging the contact element arrangements by the contact bridges provided on the doors, the two o.g. Contact elements of the first and second arrangement can be connected to live electrical leads.

Zum Aufbau dieser Anordnung können den Kontaktelementen jeweils elektrische Ableitelemente zur Kontaktierung mit elektrischen Leitungen zugeordnet sein, wobei zumindest je eines der Ableitelemente mit Kontaktelementen der ersten und zweiten Anordnung stromführend miteinander verbindbar sind. Hierzu sind diese beiden Ableitelemente vorzugsweise eng benachbart im Gehäuse angeordnet, z.B. mit einem Abstand von weniger als 5 mm, z.B. lediglich 2 bis 3 mm, wobei der Abstand noch ausreichend ist, um Luft- oder Kriechströme auf einem vorgegebenen und noch akzeptablen Niveau zu halten. Es versteht sich, dass die jeweilige Höhe der Kriech- und/oder Luftströme unter vorher definierten Bedingungen gemessen wird, wobei die Versuchsbedingungen frei gewählt oder einem üblichen Standard entsprechen können, sofern sie ausreichend definiert sind, um reproduzierbare Ergebnisse zu liefern.To construct this arrangement, the contact elements can each be associated with electrical discharge elements for contacting electrical lines, wherein at least one of the discharge elements with contact elements of the first and second arrangements can be connected to one another in a current-carrying manner. For this purpose, these two Ableitelemente are preferably arranged closely adjacent in the housing, for example, with a distance of less than 5 mm, for example, only 2 to 3 mm, the distance is still sufficient to keep air or leakage currents to a predetermined and still acceptable level , It is understood that the respective level of the creepage and / or air flows is measured under previously defined conditions, with the test conditions chosen freely or a conventional standard provided that they are sufficiently defined to give reproducible results.

Nach einer weiteren Ausführungsform kann der Türkontakt derart ausgebildet sein, daß die Kontaktelemente der ersten und der zweiten Anordnung von Kontaktelementen, die jeweils durch eine türseitige Kontaktbrücke überbrückbar sind, voneinander getrennt sind. Die beiden Kontaktelementanordnungen können somit auf unterschiedlichem Potential liegen, wenn die Tür geschlossen ist, so daß unabhängige Steuerungsfunktionen realisierbar sind.According to a further embodiment, the door contact may be formed such that the contact elements of the first and the second arrangement of contact elements, which are each bridged by a door-side contact bridge, are separated from each other. The two contact element arrangements can thus be at different potential when the door is closed, so that independent control functions can be realized.

Dadurch, daß die Kontaktelemente der ersten und zweiten Kontaktelementanordnungen bei Bedarf durch ein geeignetes Überbrückungsglied überbrückbar sind, kann zwischen zwei verschiedenen Schaltungsvarianten des Türkontaktes gewählt werden, ohne den Türkontakt austauschen zu müssen. Der Türkontakt ist hierzu vorzugsweise derart ausgeführt, daß zum Einbau des Überbrückungsgliedes lediglich der Deckel des Türkontaktes zu demontieren ist, um das Überbrückungsglied bestimmungsgemäß in den Türkontakt einsetzen zu können. Unter dieser Ausführungsform sind auch solche Türkontakte zu verstehen, bei denen elektrisch unverbundene Kontaktelemente verschiedener Kontaktelementanordnungen austauschbar sind und gegen bereits mit einem Überbrückungslied verbundene Kontaktelemente ersetzt werden können, wobei das Überbrückungsglied die den Kontaktelementen jeweils zugeordneten Ableitelemente kontaktieren kann.Characterized in that the contact elements of the first and second contact element arrangements can be bridged when required by a suitable bridging member can be selected between two different circuit variants of the door contact without having to replace the door contact. The door contact is for this purpose preferably carried out such that for installation of the bridging member only the cover of the door contact is to be dismantled in order to use the bridging member as intended in the door contact can. In this embodiment, such door contacts are to be understood in which electrically non-connected contact elements of different contact element arrangements are interchangeable and can be replaced with already connected to a bridging member contact elements, the bridging member can contact the contact elements respectively associated diverting.

Sind die beiden einander gegenüberliegenden Kontaktelementanordnungen voneinander getrennt, so führt jeweils ein Strompfad über eine elektrische Leitung zu einem der Kontaktelemente und über die an einer Tür angeordnete Kontaktbrücke zu dem zweiten Kontaktelement zu der entsprechenden elektrischen Ableitung.If the two opposing contact element arrangements are separated from one another, then in each case a current path leads via an electrical line to one of the contact elements and via the arranged on a door contact bridge to the second contact element to the corresponding electrical outlet.

Vorzugsweise sind auf dem Weg der stromführenden Verbindung zwischen den beiden stromführend miteinander verbindbaren oder verbundenen Kontaktelementanordnungen (bzw. deren Ableitelementen) Mittel zur Verringerung von Kriech- und/oder Luftströmen vorgesehen. Diese Mittel können derart wirken, dass sie den Strompfad entlang der Verbindungslinie der beiden Kontaktelementanordnungen verlängern, wobei diese Mittel von einem Überbrückungsglied elektrisch leitend überbrückbar sind. Als Mittel zur Verlängerung des Strömungspfades kann eine Trennwand bzw. ein Unterbrechungssteg vorgesehen sein, der an dem Gehäuse befestigt oder einteilig angeformt sein kann und der sich über die Verbindungslinie der beiden Kontaktelementanordnungen bzw. deren Ableitelemente erstreckt, wodurch ein möglicher Weg von Kriechströmen verlängert wird. Durch die mechanische Entfernung der Trennwand bzw. des Unterbrechungssteges kann die Anordnung eines Überbrückungsgliedes zwischen den benachbarten Ableitelementen erleichtert werden. Hierzu können entsprechende Sollbruchstellen an der Trennwand bzw. dem Unterbrechungssteg vorgesehen sein, es kann auch lediglich die Wandstärke dieser Bereiche entsprechend gewählt sein, so daß die Trennwand bzw. der Steg mittels einer Zange oder dergleichen abgebrochen werden können, ohne die angrenzenden Bereiche des Gehäuses zu beschädigen.Preferably, on the way of the current-carrying connection between the two current-carrying connectable or connected contact element assemblies (or their Ableitelementen) means for reducing creepage and / or air currents provided. These means may act to extend the current path along the connecting line of the two contact element arrangements, these means being bridged by a bridging member in an electrically conductive manner. As a means for extending the flow path may be provided a partition wall or an interruption bar which may be attached to the housing or integrally formed and which extends over the line connecting the two contact element arrangements and their Ableitelemente, whereby a possible path of leakage currents is extended. The mechanical removal of the partition wall or the interruption web, the arrangement of a bridging member between the adjacent Ableitelementen can be facilitated. For this purpose, corresponding predetermined breaking points can be provided on the partition wall or the interruption web, it can also be selected only the wall thickness of these areas, so that the partition or the web can be canceled by means of pliers or the like, without the adjacent areas of the housing to damage.

Zur Verlängerung des Weges der stromführenden Verbindung zwischen den benachbarten Ableitelementen können auch eine oder mehrere nutenförmige Vertiefungen bzw. Hinterschneidungen in dem Gehäuse vorgesehen sein oder auch Potentialsenken, die Kriechströme ableiten.To extend the path of the current-carrying connection between the adjacent Ableitelementen also one or more groove-shaped recesses or undercuts may be provided in the housing or potential wells that derive leakage currents.

Um den erfindungsgemäßen Türkontakt wahlweise in verschiedenen Schaltungsanordnungen einsetzen zu können, d.h. wahlweise mit oder ohne Überbrückungselementen, können die Eintrittsöffnungen für die elektrischen Zu- bzw. Ableitungen im Gehäuse zumindest teilweise mit an einem Gehäusebereich angeformten und entfernbaren Abdeckelementen versehen sein. Die Abdeckelemente können z.B. an dem Basisteil des Gehäuses oder an dem das Gehäuse verschließenden Deckel angeformt sein. Die Abdeckelemente können lediglich einseitig oder mit Sollbruchstellen an dem Gehäuse angeformt sein, so daß diese einfach mittels z.B. einer Zange abbrechbar sind.In order to be able to use the door contact according to the invention optionally in different circuit arrangements, ie optionally with or without bridging elements, the inlet openings for the electrical supply and discharge lines in the housing can be at least partially provided with cover elements formed and removable on a housing area. The cover elements may be formed, for example, on the base part of the housing or on the cover closing the housing. The cover can be integrally formed only on one side or with predetermined breaking points on the housing so that they easily by means such a pair of pliers are break off.

Figur 1 zeigt einen erfindungsgemäßen Türkontakt mit einem Gehäuse 1 und 2 einander gegenüberliegenden Kontaktelementanordnungen 2, 3, die jeweils zwei Kontaktelemente 4 aufweisen, die untereinander baugleich sind. Die beiden Kontaktelemente 4 der Anordnungen 2, 3 können jeweils durch eine nicht dargestellte Kontaktbrücke elektrisch leitend überbrückt werden, wozu Stifte der Kontaktbrücke in die parallel zueinander angeordneten Eintrittsöffnungen 5 des Gehäuses eingeführt werden können. Die Kontaktbrücken sind hierbei an den Türflügeln der Tür angebracht, deren Schließstellungen zu überwachen ist. Der Türkontakt ist hierbei mittig zwischen den Türen an der Türzarge oder dem angrenzenden Wandbereich angeordnet, so daß beim Schließen der Tür die beiden zugehörigen Kontaktbrücken mit dem Türkontakt bestimmungsgemäß zum Eingriff gebracht werden können. FIG. 1 shows a door contact according to the invention with a housing 1 and 2 opposite contact element assemblies 2, 3, each having two contact elements 4, which are identical to each other. The two contact elements 4 of the arrangements 2, 3 can each be electrically conductively bridged by a contact bridge, not shown, including pins of the contact bridge can be inserted into the mutually parallel inlet openings 5 of the housing. The contact bridges are hereby attached to the door leaves of the door, whose closed positions is to be monitored. The door contact is in this case arranged centrally between the doors on the door frame or the adjacent wall region, so that when closing the door, the two associated contact bridges with the door contact can be brought to service as intended.

Die Kontaktelemente 4 sind jeweils als Kegelstumpffedern ausgeführt, die aus einem spiralförmig gewickeltem Band mit vorzugsweise rechtwinkeligem bzw. rechteckigem Querschnitt bestehen. Die einzelnen Windungen der Federn überlappen einander, wodurch eine Selbstzentrierung der Kontaktflächen beim Niederdrücken der druckbeanspruchten Federn erfolgt. Die Druckplatten 6 mit den stirnseitigen Kontaktflächen 7 sind hierzu an den Kegelstumpffedern 8 dauerhaft befestigt, vorteilhafterweise angeschweißt, wobei an den gegenüberliegenden Enden des die Feder bildenden Bandes Ableitelemente 9 elektrisch leitend, in diesem Falle durch eine Punktschweißverbindung, angeordnet sind. Die Ableitelemente 9 weisen Durchgangsöffnungen zur Einführung einer Schraube auf, um zur Festlegung der elektrischen Ableitung dienenden Klemmen anzuschrauben als auch die Ableitelemente 9 an dem Gehäuse zu befestigen.The contact elements 4 are each designed as truncated cones, which consist of a spirally wound band with preferably rectangular or rectangular cross section. The individual turns of the springs overlap each other, whereby a self-centering of the contact surfaces when depressing the compression-loaded springs takes place. The pressure plates 6 with the frontal contact surfaces 7 are permanently attached to the truncated cones 8, advantageously welded, wherein at the opposite ends of the spring-forming band diverting elements 9 are electrically conductive, in this case by a spot welding connection arranged. The diverting elements 9 have through holes for insertion of a screw to screw to define the electrical discharge terminals serving as well as the diverting elements 9 to be attached to the housing.

Dadurch, daß das Gehäuse 2 jeweils durch eine an einer Tür angeordnete Kontaktbrücke überbrückbare Kontaktelementanordnungen aufweist, ist zur Überwachung der Schließstellung einer doppelflügeligen Tür, etwa einer Schiebetür, lediglich ein Türkontakt zu montieren, der bereits sämtliche erforderlichen Kontaktelemente sowie die zur elektrisch leitenden Verbindung derselben erforderlichen Einrichtungen aufweist. Durch die bestimmungsgemäße Montage des Türkontaktes sind dann bereits beide Kontaktelementanordnungen zu den jeweiligen Kontaktbrücken hin ordnungsgemäß ausgerichtet, wodurch sich der Montageaufwand erheblich vereinfacht.Characterized in that the housing 2 in each case by a arranged on a door contact bridge bridgeable contact element arrangements, to monitor the closed position of a double-leaf door, such as a sliding door, only a door contact to assemble, which already required all the contact elements and the electrically conductive connection of the same Has facilities. By proper installation of the door contact then both contact element arrangements are already properly aligned to the respective contact bridges out, which greatly simplifies the assembly effort.

Um elektrische Leitungen zu den Ableitelementen 9 führen zu können, sind Kabeldurchführungen 10 vorgesehen. Um eine möglichst kompakte Bauweise zu ermöglichen, weisen die Ableitelemente an beiden gegenüberliegenden Kontaktelementanordnungen einen nur geringen Abstand von einigen Millimetern auf, wobei die Aufnahmeräume für die Ableitelemente 9 durch eine Trennwand 11, die der Höhe der Gehäusehöhe entspricht, voneinander abgekapselt sein können, wodurch um Luft- und/oder Kriechströme sicher verhindert sind. Die Aufnahmeräume für die verschiedenen Kontaktelementanordnungen sind somit durch die Trennwand vollständig voneinder getrennt.In order to be able to lead electrical lines to the diverting elements 9, cable feedthroughs 10 are provided. In order to enable the most compact possible construction, the discharge elements on both opposing contact element arrangements only a small distance of a few millimeters, wherein the receiving spaces for the discharge elements 9 by a partition wall 11, which corresponds to the height of the housing height, can be encapsulated from each other, thereby Air and / or leakage currents are reliably prevented. The receiving spaces for the various contact element arrangements are thus completely separated from each other by the partition wall.

Im einfachsten Falle ist das Gehäuse 1 daher entlang beider parallel zu der Gehäuseebene verlaufenden Hauptachsen spiegelsymmetrisch ausgeführt. Das Gehäuse kann auch nur symmetrisch zu einer Hauptachse ausgeführt sein, wobei die Kontaktelemente der verschiedenen Kontaktelementanordnungen bei bestimmungsgemäß montiertem Türkontakt paarweise oder insgesamt auf einer Höhe angeordnet sind. Die Kontaktelemente können hierbei unter Einwirkung der an den Türen vorgesehenen Kontaktbrücken in entgegengesetzten Richtungen oder z.B. beim Einsatz bei Schwenktüren in der gleichen Richtung bewegbar sein, um eine Bewegung der Kontaktelemente unter währender Kontaktierung durch die Kontaktbrücke zu ermöglichen.In the simplest case, the housing 1 is therefore designed mirror-symmetrically along both main axes extending parallel to the housing plane. The housing can also be designed only symmetrically to a main axis, wherein the contact elements of the various contact element arrangements are arranged in accordance with the purpose mounted door contact in pairs or in total at a height. The contact elements can in this case under the action of the doors provided on the contact bridges in opposite directions or e.g. when used in swing doors in the same direction to be movable to allow movement of the contact elements while contacting through the contact bridge.

Nach der gezeigten Ausführungsform ist das Gehäuse derart ausgebildet, daß zwischen zumindest zwei Kontaktelementen der beiden gegenüberliegenden Kontaktelementanordnungen ein stromleitendes Überbrückungsglied anordenbar ist. Die Überbrückung kann hier über die Ableitelemente 9 erfolgen, gegebenenfalls können auch die Kontaktelemente 4 unmittelbar überbrückt werden. Zur Anordnung des Überbrückungsgliedes, das an den Kontaktelementen bzw. Ableitelementen dauerhaft oder lösbar befestigt sein kann, ist in dem Gehäuse eine die gegenüberliegenden Kontaktelementanordnungen verbindende Durchführung 12 vorgesehen. Diese Durchführung ist nach dem Ausführungsbeispiel in der Verbindungslinie der Ableitelemente 9 in das Gehäuse eingebracht und weist Mittel zur Minimierung von Kriech- bzw. Luftströmen in Form eines Stegs bzw. einer Trennwand 13 auf, der bzw. die über die Höhe der Kontaktflächen der Ableitelemente 9 nach oben vorsteht sowie die Durchführung 12 zumindest auf der Verbindungslinie der Ableitelemente, vorzugsweise aber über die gesamte Breite, überbrückt und hierdurch den Strompfad von möglichen Kriechströmen verlängert. Alternativ könnte das Gehäuse an der Verbindungslinie der Ableitelemente auch mit einer grabenförmigen Vertiefung versehen sein. Die Höhe des Steges 13 ist so bemessen, daß zwischen diesen und dem nicht dargestellten Gehäusedeckel ein an den Ableitelementen 9 angreifendes Überbrückungselement anordenbar ist.According to the embodiment shown, the housing is designed such that between at least two contact elements of the two opposite contact element arrangements, a current-conducting bridging member can be arranged. The bridging can take place here via the discharge elements 9, if appropriate, the contact elements 4 can be bridged directly. For arranging the bridging member, which may be permanently or detachably fastened to the contact elements or diverting elements, a passage 12 connecting the opposing contact element arrangements is provided in the housing. This implementation is introduced according to the embodiment in the connecting line of the Ableitelemente 9 in the housing and has means for minimizing creepage or air flows in the form of a web or a partition 13, the or over the height of the contact surfaces of the diverter. 9 protrudes upward and the implementation 12 at least on the connecting line of the Ableitelemente, but preferably over the entire width, bridged and thereby extends the current path of possible leakage currents. Alternatively, the housing could also be provided with a trench-shaped depression at the connecting line of the diverting elements. The height of the web 13 is dimensioned such that between these and the housing cover, not shown, an attacking on the discharge elements 9 bridging element can be arranged.

Bei dem in Figur 1 dargestellten Türkontakt können somit die einander gegenüberliegenden Kontaktelementanordnungen, die jeweils durch eine Kontaktbrücke überbrückt werden, auf unterschiedlichem Potential liegen bzw. unterschiedlichen Einrichtungen wie Steuerungs- oder Signaleinrichtungen zugeordnet sein. Hierzu sind die Ableitelemente 9 der beiden Kontaktelementanordnungen unabhängig voneinander an die entsprechenden elektrischen Zuleitungen anzuschließen. Die an einem Teil der Kabeldurchführungen 10 vorgesehenen einstückig an dem Gehäuse 1 angeformten Abdeckelemente 14 sind hierzu zu entfernen bzw. wegzubrechen. Jedem der Ableitelemente 9 wird somit eine elektrische Zuleitung zugeordnet.At the in FIG. 1 door contact shown can thus be the opposite contact element arrangements, which are each bridged by a contact bridge, at different potential or be assigned to different devices such as control or signaling devices. For this purpose, the diverting elements 9 of the two contact element arrangements are to be connected independently of one another to the corresponding electrical supply lines. The cover elements 14 integrally formed on the housing 1 on a part of the cable bushings 10 are to be removed or broken away for this purpose. Each of the diverting elements 9 is thus assigned an electrical supply line.

Alternativ kann, wie in Fig. 3 gezeigt, der Türkontakt bei identischem Gehäuse mit einem internen Überbrückungsglied 15 versehen sein, welches die einander gegenüberliegenden Kontaktelementanordnungen elektrisch leitend verbindet. Das Überbrückungsglied 15 übergreift hierzu den Steg 13, wobei nach den Figuren 3, 4 das stegförmige Überbrückungsglied 15 an den Ableitelementen 9 befestigt bzw. angeschweißt ist, so daß ein einstückiges Doppelkontaktelement resultiert. Der Türkontakt kann somit durch Austausch vorliegendeer Kontaktelemente gegen dieses Doppelkontaktelemente einfach umgerüstet werden. Das Überbrückungselement kann auch mit einem oder beiden der Ableitelemente bzw. dazugehörigen Kontaktelemente lösbar verbunden sein und durch geeignete Mittel wie z.B. Federelemente oder Formschlußmittel an die Kontaktelemente gedrückt werden. Nach der in Figur 3 dargestellten Anordnung können somit in dem Falle, daß lediglich zwei der Kontaktelemente an elektrische Leitungen angeschlossen sind (hier die beiden Kontaktelemente 16 a, 16 b der gegenüberliegenden Kontaktelementanordnungen) nur die zugeordneten Kabeldurchführungen 17a, 17b frei bzw. freigelegt sind, wobei ein Strom zwischen den beiden Kontaktelementen der beiden Kontaktelementanordnung über die an beiden Türen angeordneten Kontaktbrücken und das Überbrükkungsglied 15 fließen kann. Sämtliche Kontaktelemente des Türkontaktes liegen somit bei geschlossener Tür auf dem gleichen Potential.Alternatively, as in Fig. 3 shown, the door contact may be provided in an identical housing with an internal bridging member 15, which connects the opposing contact element assemblies electrically conductive. The bridging member 15 engages over this the web 13, wherein after the Figures 3 . 4 the web-shaped bridging member 15 is fastened or welded to the diverting elements 9, so that a one-piece double contact element results. The door contact can thus be easily converted by replacing existing contact elements against this double contact elements. The bridging element can also be detachably connected to one or both of the diverting elements or associated contact elements and pressed against the contact elements by suitable means, such as spring elements or positive locking means. After the in FIG. 3 Thus, in the case that only two of the contact elements are connected to electrical lines (here, the two contact elements 16 a, 16 b of the opposite contact element arrangements) only the associated cable bushings 17 a, 17 b are exposed or exposed, wherein a current between the two contact elements of the two contact element arrangement can flow over the contact bridges arranged on both doors and the bridging member 15. All contact elements of the door contact thus lie with the door closed at the same potential.
