Description

Die Erfindung bezieht sich auf eine Sicherheitsleiste als Schaltleiste für eine Stoß- oder Schließkantensicherung bzw. Schaltmatte gemäß dem Oberbegriff der Ansprüche 1 und 2.The invention relates to a safety strip as a switching strip for a shock or closing edge safety or safety mat according to the preamble of claims 1 and 2.

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 eine "Sicherheitsleiste" angeordnet.A safety edge z. B. according to the EP 0 234 523 A2 has an "electrical connection" and a "mounting profile" that carries a "rubber jacket profile" that can be closed by rubber caps. In the rubber jacket profile, a "safety strip" is arranged on the pressurized side of the rubber jacket profile.

Die Sicherheitsleiste z. B. gemäß der EP 0 103 726 A1 besteht im Wesentlichen aus "Isolierkörper", die üblicherweise aus Kunststoff bestehen und mittig ein "Kontaktelement" 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, wo bei der elastische Schlauch im Gummimantelprofil der Schaltleiste angeordnet wird.The safety bar z. B. according to the EP 0 103 726 A1 consists essentially of "insulating", which are usually made of plastic and centered a "contact element", wherein the contact elements end of each contact element "contact points", whereby the individual contact elements come into contact with each other energized. 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, where in the elastic hose in the rubber jacket profile of the switching strip is arranged.

Gemäß der FR 21 35 922 bestehen die Kontaktelemente aus Kugeln, die 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 consist of the contact elements of balls, which are arranged from a tube made of 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, provide the required preload with which the balls abut each other.

In der EP 0 234 523 A2 wird eine Schließkantensicherung beschrieben, bei welcher die Isolierkörper, die die Kontaktelemente aufnehmen, je aus einer Kontaktrolle bestehen, also walzenförmig ausgebildet sind, wobei die 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 zwingen. Zwischen den einzelnen Kontaktrollen sind Isolierringe angeordnet, die mit vorspringenden Keilflächen zwischen den einzelnen Kontaktrollen angeordnet sind.In the EP 0 234 523 A2 a Schließkantensicherung is described, in which the insulating body, which receive the contact elements, each consist of a contact roller, so are formed roller-shaped, wherein the contact rollers abut the contact points creatively on the front sides. Inside the contact rollers an expander cord is arranged, which force the individual contact rollers with their contact points in the axial direction to 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 A1 wird eine Schließkantensicherheitsleiste beschrieben, bei welcher die Vorspannung, mit der die Kontaktelemente aneinander anliegen, durch in Längsrichtung vorgespannter Schlauchabschnitte erzielt wird. 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 A1 a closing edge safety strip is described in which the bias voltage with which the contact elements abut each other, is achieved by longitudinally biased tube sections. The switching process 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.

In der EP 421 048 B1 wird eine Sicherheitsleiste beschrieben, die als Schaltmatte benutzt werden soll, wobei eine Vielzahl von Kontaktelementen und Keilelementen vorgesehen sind, die durch eine Expanderschnur aufeinandergezogen 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 liegt.In the EP 421 048 B1 a safety strip is described, which is to be used as a switching mat, wherein a plurality of contact elements and wedge elements are provided, 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 lies 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 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 created to make contact, consist of a hose or an expander cord, the required elasticity of this means, so the hose or the expander cord, 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.

Wie der Stand der Technik zeigt, erfordert die Herstellung einer Sicherheitsleiste bei Einsatz von volumenelastischen Hilfsmitteln den Aufwand von relativ vielen Bauteilen, wenn diese Sicherheitsleiste empfindlich reagieren soll.As the prior art shows, the production of a safety strip with the use of volume-elastic tools requires the expense of relatively many components, if this safety strip is to react sensitively.

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.

Bei dem Stromunterbrecher gemäß der DE 94 17 518 U1 ist der Aufnahmekörper elektrisch leitend und z. B. als Wendelfeder ausgebildet, die an ihren Enden die eigentlichen Kontaktstellen schafft. Die Wendelfeder wird dabei von einem nach außen über die Sicherheitsleiste vorstehenden Stößel bei Druck beaufschlagt, wird dadurch aus ihrer Ebene ausgelängt und unterbricht dadurch den Kontakt an den Kontaktstellen. Die Unterbrechung ist aber nur möglich, wenn im Bereich der Kontaktstellen bockartig ausgebildete Auflagen vorgesehen sind, auf denen sich die die Kontaktstellen tragenden Kontaktplatten abstützen, die bei Druckbeaufschlagung durch den Stößel eine Kippbwegung ausführen und dadurch die Unterbrechung des Stromes herbeiführen. Eine solche Anordnung ist nicht nur sehr aufwendig, sondern auch wenig druckempfindlich, d. h. die Schaltempfindlichkeit ist gering und hängt von der Verhaltensweise der Schraubenfeder oder eines Federblattes ab.In the circuit breaker according to the DE 94 17 518 U1 the receiving body is electrically conductive and z. B. formed as a helical spring, which creates the actual contact points at their ends. The spiral spring is acted upon by an outwardly on the safety bar projecting plunger under pressure, is thereby expelled from its level and thereby interrupts the contact at the contact points. The interruption is only possible if provided in the area of the contact points buckled pads on which support the contact points bearing contact plates, which perform a Kippbwegung when pressurized by the plunger and thereby bring about the interruption of the current. Such an arrangement is not only very expensive, but also little pressure-sensitive, ie the switching sensitivity is low and depends on the behavior of the coil spring or a spring leaf.

Bei der Schaltleiste gemäß der EP 0 172 136 A1 wird ebenfalls eine Wendelfeder eingesetzt, die die beiden an den Kontaktstellen in Kontakt elektrisch leitenden Bolzen umschließt, aber nicht elektrisch leitend ist.In the safety edge according to the EP 0 172 136 A1 a helical spring is also used, which surrounds the two electrically conductive at the contact points in contact bolt, but is not electrically conductive.

Diese bekannte Anordnung umfasst weiterhin eine Schiene sowie eine Anzahl hintereinander angeordnete Kontaktvorrichtungen, die mittels federnder Aufnahmekörper gegenüber der Schiene auf Abstand gehalten sind, wobei eine elastische Schutzhülle die Kontaktvorrichtungen umgibt und formschlüssig mit den Längsseiten der Schiene verbunden ist.This known arrangement further comprises a rail and a number of successively arranged contact devices, which are held by means of resilient receiving body with respect to the rail at a distance, wherein an elastic protective sleeve surrounds the contact devices and is positively connected to the longitudinal sides of the rail.

Diese Einrichtung ist nur einsatzfähig, wenn die zusätzlich vorgesehenen Aufnahmekörper vorgesehen sind, die wenigstens zwei der in Längsrichtung hintereinander angeordneten Kontaktelemente (Bolzen) im unbelasteten Zustand im Wesentlichen geradlinig ausgerichtet auf Abstand hält. Die Kontaktelemente (Bolzen) sind dabei bei Einwirken einer äußeren Kraft in Richtung quer zur Längserstreckung der Kontaktelemente (Bolzen) durch Formänderung der federnden Aufnahmekörper beweglich. Als Aufnahmekörder sind bei dieser bekannten Einrichtung einzelne Drahtbügel vorgesehen, wobei jeder Drahtbügel einerseits an der Schiene und andererseits an einem Halter, der mit den Kontaktelementen verbunden ist, anschließt. Auch bei dieser Anordnung erfolgt der Schaltvorgang durch einen Kippvorgang, und um die Kontaktelemente (Bolzen) funktionsbereit zu halten, sind die außer den Wendelfedern die federnden Aufnahmekörper erforderlich, die also einen zusätzlichen erheblichen Fertigungsaufwand bedeuten.This device is only operational when the additionally provided receiving body are provided, which holds at least two of the longitudinally successively arranged contact elements (bolts) in the unloaded state substantially rectilinearly spaced. The contact elements (bolts) are movable by the action of an external force in the direction transverse to the longitudinal extent of the contact elements (bolts) by changing the shape of the resilient receiving body. As a receiving conveyor single wire bracket are provided in this known device, each wire bracket on the one hand to the rail and on the other hand to a holder which is connected to the contact elements, connects. Also with this Arrangement of the switching operation by a tilting operation, and to keep the contact elements (bolts) ready to operate, the spring except the coil springs are required, which means an additional significant manufacturing effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitsleiste zu schaffen, die in ihrer Herstellung wesentlich einfacher aufgebaut ist und eine hohe Ansprechempfindlichkeit aufweist. Diese der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, dass ausgehend von einer im Oberbegriff des geltenden Hauptanspruches angeordneten Einrichtung die Aufnahmekörpern eine in sich geschlossene runde, ovale, elliptische oder polygonale Form aufweisen.The invention has for its object to provide a safety strip that is much simpler in their manufacture and has a high responsiveness. This object of the invention is based solves that starting from a arranged in the preamble of the current main claim means the receiving bodies have a self-contained round, oval, elliptical or polygonal shape.

Durch diese Ausbildung wird nicht nur ein einfacher, sicherer Aufbau erreicht, sondern gleichzeitig erfolgt das Trennen der Kontaktstellen in Längsrichtung der Kontaktelemente, wodurch die Schaltempfindlichkeit gegenüber allen anderen Einrichtungen bedeutend erhöht wird.This design not only achieves a simpler, safer construction, but at the same time separates the contact points in the longitudinal direction of the contact elements, which significantly increases the switching sensitivity to all other devices.

Vorzugsweise besteht der die Kontaktelemente aufnehmende Aufnahmekörper aus einem hochpolymeren Werkstoff, wie Kunststoff oder Gummi, wobei diese hochpolymeren Werkstoffe sich üblicherweise aus einem elastischen und einem plastischen Anteil zusammensetzen. Der elastische Anteil verhält sich dabei im Wesentlichen temperaturunabhängig, während der plastische Anteil sich temperaturabhängig verhält. Für den Einsatz bei einer Sicherheitsleiste muss also dafür Sorge getragen werden, dass der elastische Anteil des Werkstoffes relativ hoch ist, so dass die Sicherheitsleiste unabhängig von Temperaturschwankungen ihre Aufgabe erfüllt.Preferably, the receiving body receiving the contact elements made of a high polymer material, such as plastic or rubber, these high polymer materials are usually composed of an elastic and a plastic portion. The elastic portion behaves essentially independent of temperature, while the plastic portion behaves temperature-dependent. For use in a safety strip so care must be taken to ensure that the elastic portion of the material is relatively high, so that the safety bar performs its task regardless of temperature fluctuations.

Die erfindungsgemäße Sicherheitsleiste arbeitet in gleicher Weise durch den Einsatz des formelastischen Aufnahmekörpers sowohl nach dem Öffnerprinzip wie auch nach dem Schließerprinzip (Anspruch 2), wie dies nachfolgend noch verdeutlicht wird.The safety strip according to the invention works in the same way by the use of the form-elastic receiving body both after the Öffnerprinzip as well as after the NO principle (claim 2), as will be made clear below.

Zur Verdeutlichung der erfindungsgemäßen Begriffe wird sich auf die Darstellung "Stand der Technik" bezogen, die den Zeichnungen beigefügt ist.To clarify the terms according to the invention, reference is made to the illustration "prior art", which is attached to the drawings.

Die Zeichnung "Stand der Technik" zeigt den allgemeinen Aufbau einer Schaltleiste. Hier ist ein elektrischer Anschluß zur Schalteinrichtung erkennbar, wobei ein Gummimantelprofil an einem Befestigungsprofil angeordnet ist. Das Gummimantelprofil ist stirnseitig durch Gummiverschlußkappen verschlossen und trägt die eigentliche Sicherheitsleiste, die bei der Darstellung "Stand der Technik" rein schematisch ohne Bezugnahme auf die erfindungsgemäße Ausbildung dargestellt ist.The drawing "prior art" shows the general structure of a safety edge. Here, an electrical connection to the switching device can be seen, wherein a rubber jacket profile is arranged on a mounting profile. The rubber casing profile is closed at the end by rubber caps and carries the actual safety strip, which is shown in the illustration "prior art" purely schematically without reference to the inventive design.

In den Fig. 1 bis 4 ist im Schnitt eine Sicherheitsleiste 1 dargestellt mit einem Aufnahmekörper 2. Der Aufnahmekörper 2, der bei den Darstellungen in den Fig. 1 bis 4 polygonal dargestellt ausgebildet ist, trägt fest Isolierkörper 3, in denen in an sich bekannter Weise Kontaktelemente 4 angeordnet sind, die an der Kontaktstelle 5 aneinander anliegen und über elektrische Verbindungen 6, beispielsweise elektrische Leitungen, in Reihe hintereinander geschaltet sind. Da die Aufnahmekörper 2 aus elektrisch isolierendem Werkstoff bestehen, kann auf den Isolierkörper 3 auch verzichtet werden.In the Fig. 1 to 4 is shown in section a safety strip 1 with a receiving body 2. The receiving body 2, in the representations in the Fig. 1 to 4 formed polygonal, carries fixed insulating body 3, in which contact elements 4 are arranged in a conventional manner, which abut against each other at the contact point 5 and are connected in series via electrical connections 6, such as electrical lines. Since the receiving body 2 consist of electrically insulating material, it is also possible to dispense with the insulating body 3.

Hierbei ist es auch möglich, den Aufnahmekörper 2 und die Kontaktstellen 5 einstückig auszubilden, wobei aber die Kontaktstellen 5 aus einem elektrisch leitenden Werkstoff, vorzugsweise Kunststoff bestehen, der im Koextrusionsverfahren mit dem Aufnahmekörper hergestellt wird.In this case, it is also possible to form the receiving body 2 and the contact points 5 in one piece, but the contact points 5 are made of an electrically conductive material, preferably plastic, which is produced by coextrusion with the receiving body.

Bei der Ausführungsform gemäß den Fig. 1 und 2 wird das sogenannte Öffnerprinzip dargestellt. Bei Einwirken einer äußeren Kraft auf den Aufnahmekörper 2 wird dieser, wie Fig. 2 zeigt, zusammengedrückt, da der Aufnahmekörper 2 an der der einwirkenden Kraft P abgewandten Seite beispielsweise sich in dem Gummimantelprofil abstützt. Hierdurch werden die fest mit dem Aufnahmekörper 2 verbundenen Isolierkörper 3 auseinanderbewegt und hierdurch der erwünschte Schaltvorgang erreicht.In the embodiment according to the Fig. 1 and 2 the so-called opener principle is shown. Upon application of an external force on the receiving body 2 of this, as Fig. 2 shows, compressed, since the receiving body 2 on the side facing away from the applied force P side, for example, is supported in the rubber jacket profile. As a result, the fixed with the Receiving body 2 apart insulator 3 moved apart and thereby achieved the desired switching operation.

Bei der Ausführungsform gemäß Fig. 3 und 4 ist ein Aufnahmekörper 2 dargestellt, der ebenfalls Isolierkörper 3 fest trägt, die die Kontaktelemente 4 aufweisen, der aber nach dem Schließerprinzip arbeitet. Bei der Darstellung in Fig. 3 ist der Kontakt im Bereich der Kontaktstelle 5 unterbrochen und durch Einwirkung einer äußeren Kraft werden nunmehr die beiden im Aufnahmekörper 2 getragenen Isolierkörper 3 mit ihren Kontaktelementen 4 im Bereich der Kontaktstelle 5 aneinandergelegt, wodurch der gewünschte Schaltvorgang herbeigeführt wird.In the embodiment according to 3 and 4 a receiving body 2 is shown, which also carries insulating 3 fixed, which have the contact elements 4, but which operates on the NO principle. When displayed in Fig. 3 the contact in the region of the contact point 5 is interrupted and by the action of an external force, the two insulating bodies 3 carried in the receiving body 2 are now abutted with their contact elements 4 in the region of the contact point 5, whereby the desired switching operation is brought about.

Bei der Ausführungsform gemäß Fig. 5 ist eine Sicherheitsleiste 10 dargestellt, in der einzelne Aufnahmekörper 20 in Längsachse der Sicherheitsleiste 10 gesehen hintereinander angeordnet sind. Auch hier tragen die Aufnahmekörper 20 ggf. Isolierkörper 30 mit Kontaktelementen 40, wobei die einzelnen Kontaktelemente 40 der einzelnen Aufnahmekörper 20 über die elektrische Leitung 60 miteinander verbunden sind. Diese in Fig. 5 dargestellte Anordnung arbeitet nach dem Öffnerprinzip, aber kann in gleicher Weise unter Hinweis auf die Fig. 3 und 4 auch nach dem Schließerprinzip ausgebildet sein.In the embodiment according to Fig. 5 a safety strip 10 is shown, are arranged in the individual receiving body 20 seen in the longitudinal axis of the safety bar 10 one behind the other. Again, the receiving body 20 optionally insulator 30 with contact elements 40, wherein the individual contact elements 40 of the individual receiving body 20 are connected to each other via the electrical line 60. This in Fig. 5 shown arrangement operates on the Öffnerprinzip, but can in the same way with reference to the 3 and 4 be designed according to the NO principle.
