Description
Die Erfindung bezieht sich auf ein Sicherheitskontaktelement mit einem Hohlprofil als Schaltschlauch, vorzugsweise aus Gummi, nach dem Oberbegriff von Patentanspruch 1.The invention relates to a safety contact element a hollow profile as a switching tube, preferably made of rubber, after the preamble of claim 1.
Es ist eine Sicherheitskontaktschiene bekannt (EP-Patent 0 353 332 B1), die ein Hohlprofil aufweist, innerhalb dessen Profilbereiche mit elektrisch leitenden Flachen vorgesehen ist, die bei gegenseitiger Berührung zu einem Schaltimpuls führen. Dieses Hohlprofil kann innerhalb der leitenden Bereiche elektrisch leitende Drähte oder Litzen aufweisen. Diese Sicherheitskontaktschiene ist für kraftbetätigte Anlagen ausgelegt und weist zu ihrer Befestigung eine Leiste auf, wobei zwischen dem Grundkörper und der Befestigungsleiste Hinterschneidungen vorgesehen sind, mit dem sie an den Endbereichen der kraftbetätigten Anlagen, wie Rolltoren, Rollgittern usw. befestigt werden kann. Diese Sicherheitskontaktschiene ist daher zum Einzug in Dicht- und/oder Schutzprofile nicht geeignet.A safety contact rail is known (EP patent 0 353 332 B1), which has a hollow profile, within the profile areas with electrically conductive surfaces is provided when touching each other lead to a switching impulse. This hollow profile can be within the conductive areas electrically conductive wires or strands exhibit. This safety contact rail is for power-operated systems designed and has a bar for their attachment, wherein undercuts between the base body and the fastening strip are provided with which they are at the end regions of the power operated Systems such as roller shutters, rolling grilles, etc. are attached can. This safety contact rail is therefore to be used in sealing and / or Protection profiles not suitable.
Aufgabe der vorliegenden Erfindung ist es, ein Sicherheitskontaktelement mit einem Hohlprofil als Schaltschlauch zur Verfügung zu stellen, das in Hohlraume von vorhandenen Dichtprofilen an Fahrzeugen, wie Bahnen, Bussen und dergleichen montiert werden kann. The object of the present invention is a safety contact element with a hollow profile as a switching hose place that in cavities of existing sealing profiles Vehicles such as trains, buses and the like can be mounted can.
Gelöst wird die Aufgabe der Erfindung dadurch, daß zum Einzug in Dicht- und/oder Schutzprofile das Hohlprofil an seinem Umfang vorzugsweise kreisförmig, zur Innenabmessung der Dicht- und/oder Schutzprofile passend ausgebildet ist. Dadurch besteht die Möglichkeit, das Sicherheitskontaktelement in die Profile von Fahrzeugtüren einzuziehen und zwar bei der Neuausrüstung der Fahrzeuge oder auch um diese damit nachzurüsten, so daß aus den vorhandenen und bekannten Dicht- und/oder Schutzprofilen Sicherheitsprofile entstehen, bei denen dann, wenn z.B. Gegenstände eingeklemmt werden, ein Schaltimpuls ausgelöst wird, der das weitere Schließen der Türen verhindert oder diese wieder in Öffnungsrichtung umschaltet.The object of the invention is achieved in that Sealing and / or protective profiles the hollow profile on its circumference preferably circular, for the inner dimension of the sealing and / or Protective profiles are designed appropriately. This makes it possible the safety contact element in the profiles of vehicle doors move in when refitting the vehicles or also to retrofit them so that from the existing and known sealing and / or protective profiles where, e.g. Objects get caught, a switching pulse is triggered, the further closing of the Prevents doors or switches them back in the opening direction.
In vorteilhafter Weise weist das Sicherheitskontaktelement am Außenumfang Leisten auf, die in radialer Richtung elastisch verformbar sind. Die Leisten können beliebige Form und Größe aufweisen. Sie können zum Beispiel bogen- oder halkreisförmig ausgebildet sein und als Wulst entlang des Hohlprofils verlaufen. Es können auch eine Vielzahl von im Querschnitt gesehen dreieckförmigen Riefen, Rillen oder entsprechende Vorsprünge entlang des Hohlprofils vorgesehen sein. Die Leisten können auch in tangentialer Richtung geneigt angeordnet sein. Vorzugsweise sind die Leisten an ihren freien Enden schneidenartig ausgebildet, wobei zumindest ihre äußeren Begrenzungslinien bogenförmig ausgebildet sind. Dadurch lassen sich die Sicherheitskontaktelemente leicht und unter Berücksichtigung der Profil-Grenzabmaße (Toleranzen) in die Dicht- und/oder Schutzprofile einziehen und ergeben trotzdem einen guten Schaltkontakt. Dadurch, daß die Leisten im Querschnitt gesehen, freistehende dünne Enden haben und tangenial ausgerichtet sind, können sie sich dem Innendurchmesser der Dicht- und/oder Schutzprofile leicht anpassen. Durch eine Drehung des Sicherheitskontaktelement entgegen der Neigungsrichtung der Leisten können diese beim Einziehen noch besser nachgeben. In an advantageous manner, the safety contact element has Outer circumference strips that are elastically deformable in the radial direction are. The strips can have any shape and size. For example, they can have an arcuate or a semicircular shape and run as a bead along the hollow profile. It can also be one A multitude of triangular grooves, grooves, seen in cross section or corresponding projections are provided along the hollow profile be. The strips can also be inclined in the tangential direction be arranged. The strips are preferably at their free Ends formed like a knife, at least their outer Boundary lines are arcuate. Let it through the safety contact elements easily and under Consideration of the profile limit dimensions (tolerances) in the sealing and / or Pull in protective profiles and still result in a good one Switch contact. Because the strips are seen in cross section, have free-standing thin ends and are aligned tangenially, can you the inner diameter of the sealing and / or Easily adjust protection profiles. By rotating the safety contact element against the direction of inclination of the strips give in even better when pulling in.
Damit das Sicherheitskontaktelement durch Krafteinleitung von nahezu allen Seiten einen Schaltimpuls auslöst, ist zumindest eines der Profilbereiche innerhalb des Hohlprofils als ins Innere ragende Rippe ausgebildet. Dabei weist die Rippe an ihrem freien Ende einen Wulst, vorzugsweise kreisförmigen Querschnitts auf, der an seiner Oberfläche leitend ausgebildet ist. Wird nun auf das Sicherheitskontaktelement eine Kraft ausgeübt, so braucht lediglich der zweite Profilbereich mit seiner elektrisch leitenden Fläche um weniger als den radialen Abstand verbogen zu werden bis ein Schaltimpuls ausgelöst wird. Die Leitfähigkeit und Möglichkeit des elektrischen Anschlusses zur Signalübertragung wird noch dadurch verbessert, daß innerhalb der Rippe, vorzugsweise innerhalb des Wulstes, zumindest ein elektrisch leitender Draht oder Litze aus Metall, Kohle- bzw. Grafitfasern oder dergleichen eingelagert ist.So that the safety contact element by applying force from triggers a switching pulse on almost all sides, is at least one the profile areas within the hollow profile as projecting into the interior Rib trained. The rib has one at its free end Bead, preferably circular cross-section, on its Surface is conductive. Now on the safety contact element exerted a force, only the second needs Profile area with its electrically conductive surface by less than the radial distance to be bent until a switching pulse is triggered becomes. The conductivity and possibility of electrical Connection for signal transmission is further improved by that inside the rib, preferably inside the bead, at least one electrically conductive wire or strand made of metal, carbon or Graphite fibers or the like is embedded.
In vorteilhafter Weise umfaßt der andere Profilbereich mit seiner elektrisch leitenden Fläche den neben der Rippe liegenden Innenbereich des Hohlprofils, wobei damit, abgesehen von dem Befestigungsbereich der Rippe an dem Hohlprofil, der übrige Innenbereich eine elektrisch leitende Fläche bildet. Um den Kontakt der elektrisch leitenden Flächen zueinander dadurch zu verbessern, daß der Abstand geringer ist und daß durch gezielte Berührung die Kontakgabe verbessert wird, weist der Innenbereich mehrere vorstehende Vorsprünge auf, die zusammen mit ihren Zwischenbereichen aus elektrisch leitendem Material hergestellt sind. Die Leitfähigkeit und Möglichkeit des elektrischen Anschlusses zur Signalübertragung wird noch dadurch verbessert, daß innerhalb des Innenbereichs, vorzugsweise innerhalb zumindest eines Vorsprungs ein elektrisch leitender Draht oder Litze aus Metall, Kohle- bzw. Grafitfaser oder dergleichen eingelagert ist.The other profile area advantageously comprises with its electrical conductive surface the inner area lying next to the rib of the hollow profile, with the exception of the fastening area the rib on the hollow profile, the rest of the inner area one forms an electrically conductive surface. To the contact of the electrical conductive surfaces to improve each other by making the distance is less and that through targeted contact the contact is improved, the inner region has several protruding projections on that out along with their intermediate areas are made of electrically conductive material. The conductivity and Possibility of electrical connection for signal transmission further improved by the fact that inside, preferably an electrically conductive within at least one projection Wire or strand made of metal, carbon or graphite fiber or the like is stored.
Um die elektrisch leitenden Flächen elektrisch voneinander zu trennen, ist der Rippengrund im Übergangsbereich zum Hohlprofil aus nicht leitende Material, insbesondere Gummi, hergestellt. Um das Hohlprofil nach außen nicht leitend auszubilden, durchdringt der nicht leitende Übergangsbereich am Rippengrund das Hohlprofil, wobei sich daran ein nicht leitender Umfangsbereich anschließt, der das ganze Hohlprofil hülsenartig umfaßt. In vorteilhafter Weise sind auch die Leisten aus nicht leitendem Material hergestellt und an den Umfangsbereich angeformt.To electrically separate the electrically conductive surfaces separate, the rib base is in the transition area to the hollow profile made of non-conductive material, especially rubber. To do that Not forming a hollow profile to the outside does not penetrate conductive transition area at the base of the rib the hollow profile, wherein this is followed by a non-conductive peripheral area that the entire hollow profile includes sleeve-like. Are also advantageous the strips made of non-conductive material and to the peripheral area molded.
Ein solches Sicherheitskontaktelement bzw. das Hohlprofil läßt sich aus extrudierbarem Material, insbesondere Polymeren, einstückig durch extrudieren herstellen, so daß ein vom Fertigungsverfahren her gesehen, endloser Schlauch entsteht, der leitende Bereiche und nicht leitende Bereiche einschließlich der Drähte und Litzen und der übrigen Teile umfaßt.Such a safety contact element or the hollow profile can be made of extrudable material, in particular polymers, in one piece produce by extrusion, so that from the manufacturing process seen, endless hose is created, the conductive areas and not conductive areas including the wires and strands and the includes other parts.
Zur weiteren Erläuterung der Erfindung wird auf die Zeichnung verwiesen, in der ein Querschnitt durch das Sicherheitskontaktelement dargestellt ist.To further explain the invention, reference is made to the drawing, in which a cross section through the safety contact element is shown.
In der Abbildung ist allgemein mit 1 das Sicherheitskontaktelement
bezeichnet, das als Hohlprofil 2 ausgebildet ist. Das Hohlprofil 2 ist
an seinem Außenumfang 3 im wesentlichen kreisförmig ausgeführt
und passend zur Innenabmessung 4 eines Dicht- und/oder Schutzprofils
ausgebildet. An dem Außenumfang 3 sind Leisten oder
Noppen angeformt. Die Leisten sind tangential geneigt und laufen an
ihren freien Enden schneidenartig aus. Durch ihre Ausgestaltung sind
die Leisten 5 radial nachgiebig elastisch angelenkt, so daß sie beim
Einführen des Hohlprofils in das Dicht- und/oder Schutzprofil sich an
der Innenabmessung anlegen und dadurch einen guten Kontakt bei
Krafteinwirkung auf das Dicht- und/oder Schutzprofil haben und die
Verformung in das Hohlprofil weiterleiten. Im Inneren des Hohlprofils
2 ist eine Rippe 6 angeordnet, die an ihrem freien Ende einen Wulst 7
aufweist, in dem ein elektrisch leitender Draht 8, ohne Isolierung zur
besseren Leitfähigkeit eingelagert ist. Der Rippengrund 9, der in der
Abbildung schraffiert dargestellt ist, ist aus nicht leitendem Material
hergestellt und durchdringt das Hohlprofil, wobei sich ein nicht
leitender Umfangsbereich anschließt, der um das gesamte Hohlprofil
herumläuft und die Leisten mit beinhaltet. Der Übergangsbereich
zwischen leitendem und nicht leitendem Gummi ist zwar bei genauer
Betrachtung sichtbar, er hat aber keine feste Trennlinie, wie sie der
Einfachheit halber in der Abbildung dargestellt ist. Es handelt sich
dadurch, daß das gesamte Hohlprofil einstückig extrudiert ist, um
einen homogenen Übergangsbereich. Beidseitig des Rippengrunds 9
schließt sich der Innenbereich 11 an, der wiederum leitend ausgeführt
ist und mehrere Vorsprünge 12 aufweist, wobei zumindest in einem
Vorsprung ein elektrisch leitender Draht ohne Isolierung direkt
eingelagert ist, um die Leitfähigkeit entlang des Hohlprofils, wie im
Wulst, zu verbessern. Es können auch in mehreren oder in allen
Vorsprüngen Drähte eingelagert sein. Durch die Vorsprünge wird der
Schaltweg, der erforderlich ist, um einen Kontakt zwischen der
Oberfläche der Vorsprünge und dem Wulst herzustellen, verringert.
Durch die schneidenartige Anformung der Vorsprünge wird bei einer
Betätigung / Schaltung der Kontaktübergangswiderstand minimiert.
Deshalb ist der Querschnitt des Wulstes und die Größe der
Vorsprünge, so wie sie in der Abbildung dargestellt sind, nicht
unbedingt maßstabsgetreu. Sie können so variiert werden, daß
bezogen auf den Verwendungszweck ein Schaltimpuls bei bestimmter
vorgegebener Verformung gewährleistet ist bzw. erfolgt. Um
möglichst von allen Seiten bei gleichem Verformungsweg einen
Schaltimpuls auszulösen, ist der Wulst der Rippe etwa im Zentrum
des Hohlprofils angeordnet und die Vorsprünge gleichmäßig über den
Innenraum verteilt und von gleicher Größe.In the illustration, the safety contact element is generally 1
