Description

Die Erfindung bezieht sich auf eine Sicherheitsleiste als Schaltleiste gemäß dem Oberbegriff des Anspruches 1.The invention relates to a safety strip as a safety edge according to the preamble of claim 1.

Eine Schaltleiste z. B. gemäß der EP 0 234 523 A2 weist einen "elektrischen Anschluß" auf und ein "Befestigungsprofil", das ein "Gummimantelprofil" trägt, das durch Gummiverschlußkappen verschlossen werden kann. In dem Gummimantelprofil ist an der druckbeaufschlagten Seite des Gummimantelprofils eineA safety edge z. B. according to the EP 0 234 523 A2 has an "electrical connection" and a "mounting profile" which carries a "rubber jacket profile" which can be closed by rubber caps. In the rubber jacket profile is on the pressurized side of the rubber jacket profile a

"Sicherheitsleiste" angeordnet."Safety bar" arranged.

Die Sicherheitsleiste gemäß der EP 0 103 726 A1 besteht im wesentlichen aus "Isolierkörper", die üblicherweise aus Kunststoff bestehen und mittig "Kontaktelemente" aufweisen, wobei die Kontaktelemente endseitig an jedem Kontaktelement "Kontaktstellen" aufweisen, womit die einzelnen Kontaktelemente untereinander stromführend in Kontakt kommen. Diese Kontaktelemente mit ihren Isolierkörpern und Kontaktstellen sind in einem "Aufnahmekörper", einem in Längsrichtung vorgespannten Schlauch angeordnet und werden von diesem getragen, wobei der elastische Schlauch im Gummimantelprofil der Schaltleiste angeordnet wird.The safety bar according to the EP 0 103 726 A1 consists essentially of "insulating", which are usually made of plastic and having "contact elements" in the center, wherein the contact elements end of each contact element "contact points", whereby the individual contact elements come in contact with each other live. These contact elements with their insulating bodies and contact points are arranged in a "receiving body", a longitudinally biased hose and are supported by this, wherein the elastic hose is arranged in the rubber jacket profile of the switching strip.

Gemäß der FR 21 35 922 bestehen die Kontaktelemente aus Kugeln, die in einem aus einem aus weichem Werkstoff bestehenden Schlauch angeordnet sind. Die Kugeln weisen einen Durchmesser auf, der etwas kleiner ist als der Innendurchmesser des weichen Schlauches, wobei während des Einfüllens der Kugeln in den Schlauch, der Schlauch elastisch gelängt wird. Noch in diesem gelängten Zustand werden die beiden Mündungen des Schlauches mit Stopfen verschlossen, an die die elektrischen Zuleitungen anschließen. Die Stopfen erzeugen in Verbindung mit dem gespannten Schlauch innerhalb des gespannten Schlauches die erforderliche Vorspannung, mit der die Kugeln aneinander anliegen.According to the FR 21 35 922 The contact elements consist of balls which are arranged in a tube made of a soft material. The balls have a diameter which is slightly smaller than the inner diameter of the soft tube, wherein during the filling of the balls in the hose, the hose is elastically elongated. Even in this extended state, the two mouths of the hose are closed with plugs, which connect the electrical leads. The plugs, in conjunction with the tensioned hose within the tensioned hose, produce the required preload with which the balls abut each other.

In der EP 0 234 523 wird eine Schließkantensicherung beschrieben, bei welcher die Isolierkörper, die die Kontaktelemente aufnehmen, je aus einer Kontaktrolle bestehen, also walzenförmig ausgebildet sind, wobei diese Kontaktrollen an den Stirnseiten die Kontaktstellen schaffend aneinander anliegen. Im Inneren der Kontaktrollen ist eine Expanderschnur angeordnet, die die einzelnen Kontaktrollen mit ihren Kontaktstellen in axialer Richtung aufeinanderzu zwingt. Zwischen den einzelnen Kontaktrollen sind Isolierringe angeordnet, die mit vorspringenden Keilflächen zwischen den einzelnen Kontaktrollen angeordnet sind.In the EP 0 234 523 a closing edge safety device is described, in which the insulating body, which receive the contact elements, each consist of a contact roller, so are formed roller-shaped, these contact rollers abut the contact points creatively on the front sides. Inside the contact rollers, an expander cord is arranged, which forces the individual contact rollers with their contact points in the axial direction toward each other. Between the individual contact rollers insulating rings are arranged, which are arranged with projecting wedge surfaces between the individual contact rollers.

In der DE 196 47 720 wird eine Schließkantensicherheitsleiste beschrieben, bei welcher die Vorspannung, mit der die Kontaktelemente aneinander anliegen, durch in Längsrichtung vorgespannte Schlauchabschnitte erzielt wird. Diese Schlauchabschnitte übergreifen jeweils zwei Kontaktelemente und drücken die übergriffenen Kontaktelemente gegeneinander. Die Schaltung erfolgt aufgrund einer Kippbewegung der Kontaktelemente gegeneinander und der Schaltvorgang wird durch Kippzonen bildende Wulste erreicht. Ausgehend von der Einrichtung gemäß der EP 0 103 736 A1 ist hier also der durchgehende Schlauch aufgelöst in einzelne Schlauchstücke, wodurch die Wartbarkeit verbessert werden soll.In the DE 196 47 720 a Schließkantensicherheitsleiste is described in which the bias voltage with which the contact elements abut each other, is achieved by longitudinally biased tube sections. These tube sections engage over two contact elements and press the overlapped contact elements against each other. The circuit is due to a tilting movement of the contact elements against each other and the switching operation is achieved by tipping zones forming beads. Starting from the device according to the EP 0 103 736 A1 So here is the continuous hose dissolved into individual pieces of tubing, whereby the maintainability is to be improved.

Aus der DE 100 02 926 C1 ist eine Sicherheitsleiste als Schaltleiste bekanntgeworden, bei der die Spannvorrichtung, mit der die einzelnen Kontaktelemente aufeinanderzu gezwungen werden, als Vorspannelemente ausgebildet sind, wobei die Vorspannelemente form- oder kraft- oder materialschlüssig mit den Kontaktelementen verbunden sind und die Verbindung der Vorspannelemente miteinander die erforderliche Vorspannung der Kontaktelemente bewirkt. Bei einer solchen Einrichtung ist kein die Vorspannung erzeugender Schlauch oder keine die Vorspannung erzeugende Expanderschnur erforderlich, sondern die Aufnahmekörper für die Kontaktelemente selbst sind als Vorspannelemente ausgebildet. Durch diese Anordnung ist eine langgestreckte Schaltleiste erreichbar.From the DE 100 02 926 C1 a safety strip has become known as a switching strip, in which the clamping device with which the individual contact elements are forced toward each other, are formed as biasing elements, the biasing elements form or force or materially connected to the contact elements and the connection of the biasing elements together the required bias causes the contact elements. In such a device, no tube generating the bias voltage or no expander cord generating the bias is required, but the receiving bodies for the contact elements themselves are formed as biasing elements. By this arrangement, an elongated safety edge is accessible.

Schließlich wird in der EP 421 048 B1 eine Sicherheitsleiste beschrieben, die als Schaltmatte benutzt werden soll, wobei eine Vielzahl von Kontaktelementen und Keilelementen vorgesehen sind, die durch eine Expanderschnur aufeinanderzu gezogen werden. Die Keilelemente sind als Keilplatten, die Kontaktelemente als Kontaktplatten ausgebildet, wobei im schaltbereiten Zustand die Expanderschnur in den Kontaktplatten und in den Keilplatten in unterschiedlicher Höhe liegen.Finally, in the EP 421 048 B1 described a safety strip to be used as a switching mat, wherein a plurality of contact elements and wedge elements provided are, which are pulled together by an expander cord. The wedge elements are designed as wedge plates, the contact elements as contact plates, wherein in the switch-ready state, the expander cord lie in the contact plates and in the wedge plates at different heights.

Unabhängig davon, ob die elastische Vorspannung, mit der die Kontaktelemente aneinander Kontakt schaffend angelegt werden aus einem Schlauch, aus Schlauchabschnitten, Vorspannelementen oder einer Expanderschnur bestehen, wird die erforderliche Elastizität dieses Mittels, also des Schlauches oder der Expanderschnur durch Volumenelastizität erreicht, d. h. der Schlauch oder die Expanderschnur verringern ihr Volumen bei Einwirken der äußeren Kraft, und wenn diese äußere Kraft wegfällt, nehmen diese Hilfsmittel ihr äußeres Volumen wieder an.Regardless of whether the elastic bias, with which the contact elements are made to create contact from a hose, hose sections, biasing elements or an expander cord, the required elasticity of this means, ie the hose or the expander cord is achieved by volume elasticity, d. H. the tube or expander cord reduces its volume upon application of external force, and when that external force ceases, these aids resume their outer volume.

Wird ein durchgehender Schlauch oder eine Expanderschnur eingesetzt, muß bei Auseinanderdrücken der Kontaktelemente der gesamte, über die Länge der Sicherheitsleiste reichende Schlauch oder die gesamte, über die Länge der Sicherheitsleiste reichende Expanderschnur gelängt werden. Eine individuelle Vorspannung für jeden einzelnen Bereich der Sicherheitsleiste ist in einem solchen Fall nicht möglich.If a continuous hose or an expander cord is used, when the contact elements are pushed apart, the entire hose extending over the length of the safety strip or the entire expander cord extending over the length of the safety strip must be elongated. An individual bias for each area of the safety bar is not possible in such a case.

Besteht das die Vorspannung erzeugende Hilfsmittel aus Schlauchabschnitten, ist eine Schaltung nur über ein Kippen mittels Kippzonen möglich, wobei in vielen Einsatzfällen eine solche Kippschaltung als zu unempfindlich angesehen wird.Is the bias generating tool from hose sections, a circuit is only possible by tilting by means of tilting zones, and in many cases such a flip-flop circuit is considered to be too insensitive.

Es sind auch Aufnahmekörper bekanntgeworden, die nicht aus volumenelastischem Werkstoff bestehen, sondern die Aufnahmekörper bestehen aus metallischen Wendelfedern oder metallischem Federblech.There are also known receiving body, which do not consist of volume-elastic material, but the receiving body consist of metallic coil springs or metallic spring plate.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Sicherheitsleiste zu schaffen, die eine hohe Ansprechempfindlichkeit aufweist und bei der problemlos zwei Stromkreise realisiert werden können.The invention is therefore an object of the invention to provide a safety bar, which has a high sensitivity and can easily be realized in the two circuits.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst, der im Oberbegriff von der Einrichtung gemäß der EP 0 234 523 ausgeht.This object of the invention is achieved by the teaching of the main claim, in the preamble of the device according to the EP 0 234 523 emanates.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous embodiments are explained in the subclaims.

Die Kontaktleisten können langgestreckt ausgebildet sein oder auch als kurze Bauteile gestaltet sein, je nach Einsatzzweck und geometrischer Figur der eigentlichen Sicherheitsleiste.The contact strips can be elongated or designed as short components, depending on the purpose and geometric figure of the actual safety bar.

Die Vorspannung wird durch ein Vorspannelement erzielt, das sowohl volumenelastisch wie formelastisch arbeiten kann.The bias is achieved by a biasing element, which can work both volume elastic and form-elastic.

Sollen mit einer Kontaktleiste zwei Stromkreise realisiert werden, führen kleine Unebenheiten, Reibungen, Biegungen usw. zu einem undefinierten Schaltzustand, der fertigungstechnisch bei den bisherigen Anordnungen nicht herstellbar und beherrschbar war.If two circuits are to be realized with a contact strip, small unevenness, friction, bending, etc. lead to an undefined switching state which could not be produced and controlled in terms of production engineering in the previous arrangements.

Dieses Problem wird dadurch gelöst, daß bei der Ausbildung von zwei Stromkreisen zwei äußere Kontaktleisten und eine einstückige mittlere Kontaktleiste vorgesehen ist, wobei die beiden äußeren Kontaktleisten Kontaktelemente aufweisen, die mit Kontaktelementen der mittleren Kontaktleiste in Kontakt treten können.This problem is solved in that in the formation of two circuits, two outer contact strips and a one-piece middle contact strip is provided, the two outer contact strips have contact elements that can come into contact with contact elements of the middle contact strip.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Hierbei zeigt

Fig. 1
eine Sicherheitsleiste, bei der zwei Stromkreise realisiert werden können und in
Fig. 2
eine Draufsicht auf die Anordnung gemäß Fig. 1 bei abgenommener Abdeckplatte.

Fig. 2
a plan view of the arrangement of FIG. 1 with removed cover plate.

Bei der Ausführungsform gemäß Fig. 1 ist eine Bodenplatte 20 trogförmig ausgebildet und nimmt in diesem Trog die Kontaktleisten auf, die, wie dies besonders deutlich Fig. 7 zeigt, einmal aus den beiden Kontaktleisten 1 und 2 bestehen, die als äußere Kontaktleisten bezeichnet werden können, während eine mittlere, einstückige Kontaktleiste 2a vorgesehen ist. Die beiden äußeren Kontaktleisten 1 und 2 tragen die Kontaktelemente 3, während die mittlere Kontaktleiste 2a die Kontaktelemente 4 trägt. Durch diese Anordnung wird ein Stromkreis 22 und ein Stromkreis 23 gebildet. Diese Gesamtanordnung wird durch bei dem dargestellten Ausführungsbeispiel in der trogartigen Bodenplatte angeordnete Spannelemente 6 unter Vorspannung gesetzt, wobei die Spannelemente 6 als volumenelastische Druckelemente ausgebildet sind und sich beispielsweise über die gesamte Länge der Sicherheitsleiste erstrecken können. Die Isolierkeilelemente 5 sind natürlich bei dieser Ausführungsform gemäß den Fig. 1 und 2 ebenfalls doppelt ausgebildet.In the embodiment of FIG. 1, a bottom plate 20 is formed trough-shaped and accommodates in this trough the contact strips, which, as shown particularly clearly Fig. 7, once from the two contact strips 1 and 2, which can be referred to as outer contact strips while a middle, one-piece contact strip 2a is provided. The two outer contact strips 1 and 2 carry the contact elements 3, while the middle contact strip 2a carries the contact elements 4. By this arrangement, a circuit 22 and a circuit 23 is formed. This overall arrangement is biased by arranged in the illustrated embodiment in the trough-like bottom plate clamping elements 6, wherein the clamping elements 6 are formed as volume elastic pressure elements and can extend over the entire length of the safety strip, for example. The Isolierkeilelemente 5 are of course also doubly formed in this embodiment according to FIGS. 1 and 2.
