Description

Die Erfindung bezieht sich auf eine Schließkanten-Sicherung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a closing edge fuse according to the preamble of claim 1.

Eine Schließkanten-Sicherung wird in der FR 21 35 922 A1 beschrieben. Bei dieser Anordnung sind in einem aus weichem Werkstoff bestehenden Schlauch Kugeln angeordnet, die vorzugsweise aus Stahl bestehen und einen Durchmesser aufweisen, 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 Kontaktleitungen anschließen. Die Stopfen erzeugen in Verbindung mit dem gespannten Schlauch innerhalb des gespannten Schlauches die erforderliche Vorspannung, mit der die Kugeln aneinander anliegen. A closing edge safety device is described in FR 21 35 922 A1. With this arrangement are made of soft Material existing hose balls arranged, preferably consist of steel and have a diameter, which is slightly smaller than the inside diameter of the soft one Hose, while during the filling of the balls in the Hose the hose is stretched elastically. Still in this elongated state are the two mouths of the hose sealed with a plug to which the contact leads connect. The plugs produce in connection with the tensioned Hose within the tensioned hose required preload with which the balls are in contact with each other.

Werden die Kugeln durch einen örtlichen Verformungsdruck voneinander entfernt, wird der Strom unterbrochen und ein Signal erzeugt.The balls are subjected to a local deformation pressure apart from each other, the power is cut off and on Signal generated.

Die bekannte Anordnung hat in der Praxis keinen Eingang gefunden, da die Kugeln sich in dem weichen Schlauch nicht zentrieren, sondern um der erzeugten Vorspannung durch den Schlauch auszuweichen, gegeneinander verschieben, so daß keine geradlinige Kugelkette im Endeinbauzustand vorliegt. Die Kugeln können dabei die äußere Oberfläche des Schlauches verformen, so daß Schwierigkeiten beim Einbau des Schlauches bestehen, aber auch die nicht zentrierten Kugeln verhindern ggf. bei Auftreten des örtlichen Verformungsdruckes die notwendige Signalgebung.The known arrangement has not been used in practice, because the balls don't center in the soft tube, but about the generated preload by the Dodge hose, move against each other, so that there is no straight ball chain in the final installation state. The Balls can cover the outer surface of the hose deform so that difficulties in installing the hose exist, but the non-centered balls may also prevent the necessary when the local deformation pressure occurs Signaling.

In der WO/97 38 199 wird eine Schließkanten-Sicherung beschrieben, bei welcher in einem elastischen Schlauch ein der Form der Kontaktelemente angepaßtes, die Kontaktelemente jeweils einzeln aufnehmendes, elastisches Kontaktelementebett ausgearbeitet ist, das ortsfest in bezug zum Schlauch und an der kraftbeaufschlagten Seite des Schlauches angeordnet ist, so daß die Kontaktelemente einerseits ortsfest in dem Kontaktelementebett gelagert sind und andererseits der Biegeradius in der Mittelachse der durch die Kontaktelemente gebildeten Kontaktkette größer ist als der Biegeradius des eigentlichen Kontaktelementebettes. In dieser Literaturstelle wird auch vorgeschlagen, daß zusätzlich die Kontaktelemente von einer Expanderschnur durchzogen sein können.WO / 97 38 199 describes a closing edge safety device in which one of the elastic tubes Adapted shape of the contact elements, the contact elements each individually accommodating, elastic contact element bed is worked out, the stationary with respect to the hose and on the pressurized side of the hose is arranged, so that the contact elements are stationary on the one hand in the contact element bed are stored and on the other hand the bending radius in the Central axis of the contact chain formed by the contact elements is greater than the bending radius of the actual contact element bed. This reference also suggests that in addition the contact elements of an expander cord can be pulled through.

Diese Anordnung ist aufwendig, da das Ausformen der Kontaktelementebetten natürlich einen Formaufwand bedeutet und sichergestellt sein muß, daß die Anordnung der Kontaktelementebetten und die Größe der Kontaktelemente derart zueinander angepaßt ist, daß sich im Ruhezustand die Kontaktelemente berühren. This arrangement is complex because the contact elements are shaped of course means a formal effort and it must be ensured that the arrangement of the contact element beds and the size of the contact elements to each other is adapted that the contact elements in the idle state touch.

In der EP 0 234 523 A wird eine Schließkanten-Sicherung beschrieben, bei welcher die Kontaktelemente je aus einer Kontaktrolle bestehen, also walzenförmig ausgebildet sind, wobei die Kontaktrollen an den Stirnenden 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 radial zur Isolierringachse ausgerichteten, in den Innenraum der Isolierringe vorspringenden Keilflächen zwischen den einzelnen Kontaktrollen angeordnet sind.EP 0 234 523 A describes a closing edge safety device in which the contact elements each from a contact roll exist, that is, are cylindrical, the Contact rollers at the front ends creating contact points to each other issue. There is an expander cord inside the contact rolls arranged that the individual contact roles with their Force contact points towards each other in the axial direction. Between insulating rings are arranged on the individual contact rollers, those with radially aligned to the insulating ring axis, in the interior of the insulating rings projecting wedge surfaces between the individual contact roles are arranged.

Der Herstellungsaufwand für diese Schließkanten-Sicherung ist relativ hoch.The manufacturing effort for this closing edge fuse is quite high.

Der Erfindung liegt die Aufgabe zugrunde, eine Schließkanten-Sicherung zu schaffen, bei der sichergestellt sein soll, daß die eingesetzten Kontaktelemente, vorzugsweise Kugeln oder kugelähnliche Teile, korrekt ausgerichtet sind, trotzdem aber auf den geringsten Verformungsdruck signalgebend reagieren. Weiterhin soll der Herstellungsaufwand aber niedrig gehalten werden.The invention has for its object a closing edge fuse to create, to ensure that the used contact elements, preferably balls or ball-like Parts that are correctly aligned, but still on react the lowest deformation pressure signaling. Furthermore, the manufacturing effort should be kept low become.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Anspruches 1 gelöst.This object of the invention is achieved by Doctrine of claim 1 solved.

Vorteilhafte Ausgestaltungen sind in den eigentlichen Unteransprüchen erläutert.Advantageous refinements are in the actual subclaims explained.

Während bei allen bisher zum Stand der Technik gehörenden Sicherheitsleisten erhebliche Aufwendungen dafür gemacht werden, daß die Kontaktelemente, gleichgültig ob diese als Kugeln, Walzen oder wie auch immer ausgebildet sind, an ihren Kontaktstellen aneinandergepreßt werden, wird nunmehr gemäß der Erfindung der Vorschlag gemacht, daß die Kontaktierung der einzelnen Kontaktelemente miteinander lediglich durch die Schwerkraft, d. h. durch das Gewicht der Kontaktelemente dann erfolgen kann, wenn die Sicherheitsleiste vertikal ausgerichtet ist. Hierbei wird selbstverständlich eine um so bessere Kontaktierung der Elemente miteinander erreicht, je schwerer die Elemente sind, aber auf jeden Fall haben die Elemente ein Gewicht, das ausreicht, bei lotrechtem Einbau der Sicherheitsleiste kontaktgebend aneinander anzuliegen.While all of the prior art so far Security strips made considerable effort for this that the contact elements, whether they are spheres, Rollers or whatever are trained on their Contact points are pressed together, is now according to the invention made the proposal that contacting the individual contact elements with each other only by Gravity, d. H. then by the weight of the contact elements can be done if the safety bar is aligned vertically is. This will of course make contacting all the better the elements reached each other, the heavier the elements are, but in any case the elements have a weight that is sufficient if the safety bar is installed vertically to be in contact with each other.

Gemäß Anspruch 2 werden die Kontaktelemente als teilkugelförmige Kugeln ausgebildet, die umlaufende Kontaktflächen aufweisen. Hierdurch wird eine bessere Kontaktbildung erreicht, eine größere Berührungsfläche sichergestellt, so daß ein geringerer Widerstand bewirkt wird und die Zentrierung der Kontaktelemente ist besser und leichter.According to claim 2, the contact elements are partially spherical Balls formed, which have circumferential contact surfaces. In this way, better contact formation is achieved, ensures a larger contact area, so that a smaller Resistance is caused and the centering of the contact elements is better and easier.

Gemäß einem Vorschlag der Erfindung werden die Kontaktelemente als einfache Kugeln ausgebildet.According to a proposal of the invention, the contact elements designed as simple balls.

Weiterhin wird gemäß der Erfindung vorgesehen, daß das Kontaktelement dabei so aufgebaut sein kann, daß eine leitfähige Hülse eingesetzt wird, um die ein Mantel aus Kunststoff gespritzt wird. Die Hülse weist dabei planparallele Flächen auf.Furthermore, it is provided according to the invention that the contact element can be constructed so that a conductive Sleeve is inserted around which a plastic jacket is injection molded becomes. The sleeve has plane-parallel surfaces.

In Fig. 1 ist zum besseren Verständnis der Erfindung eine Schließkantensicherung dargestellt, die aus einem Profilelement P besteht, das an der zu sichernden Schließkante angeschlossen werden kann. Dieses Profilelement P weist an seiner der zu sichernden Kante hin gerichteten Seite einen Aufnahmeraum auf, in dem eine Sicherheitsleiste S angeordnet ist, auf deren Ausbildung und Gestaltung sich die Erfindung bezieht.In Fig. 1, a closing edge safety device is shown for a better understanding of the invention, which consists of a profile element P , which can be connected to the closing edge to be secured. This profile element P has, on its side facing the edge to be secured, a receiving space in which a safety strip S is arranged, the design and configuration of which the invention relates to.

In der Zeichnung gemäß Fig. 2 ist mit 1 ein Abschnitt einer Sicherheitsleiste bezeichnet, die durch einen Schlauch 3 gebildet wird, der aus einem flexiblen, weichelastischen Material besteht, das z. B. eine Shorehärte von 40 Shore aufweisen kann. Hierbei kann der Schlauch einen weichen Kern aufweisen und eine etwas härtere oder abriebfester gestaltete Oberfläche und wird vorzugsweise aus einem thermoplastischen Elastomer gefertigt. Der Schlauch 3 kann auch aus einem Moosgummi gebildet werden, das mit einem entsprechenden Bezug als Oberfläche ausgerüstet ist.2, 1 is a section of a Security bar referred to, which is formed by a hose 3 which is made of a flexible, flexible material, the Z. B. may have a Shore hardness of 40 Shore. The tube can have a soft core and a somewhat harder or more abrasion-resistant surface and is preferably made from a thermoplastic elastomer. The tube 3 can also be formed from a foam rubber with a corresponding reference as a surface is equipped.

Innerhalb des Schlauches 3 sind Kontaktelemente 2 angeordnet, die bei dem dargestellten Ausführungsbeispiel gemäß Fig. 2 und 3 aus Kugeln 2a gebildet werden. Die in den Endbereichen der Schließkanten-Sicherung 1 erforderlichen elektrischen Anschlußkontakte sind aus Übersichtlichkeitsgründen in der Zeichnung nicht dargestellt und gehören zum Stand der Technik.Contact elements 2 are arranged inside the hose 3, those in the illustrated embodiment according to FIG. 2 and 3 are formed from balls 2a. The in the end areas the closing edge fuse 1 required electrical For reasons of clarity, connection contacts are in the Drawing not shown and belong to the prior art.

Fig. 3 zeigt, daß bei Einwirken eines örtlichen Verformungsdruckes die der Druckeinwirkung zugewandte Wandung des Schlauches 3 ein Auseinanderziehen der Kugeln 2a bewirkt, wodurch der Ruhestrom unterbrochen wird und dadurch das gewünschte Signal erzeugt wird.Fig. 3 shows that under the action of a local deformation pressure the wall of the pressure facing Hose 3 causes balls 2a to pull apart, whereby the quiescent current is interrupted and thereby the desired signal is generated.

Wird die Sicherheitsleiste lotrecht, d. h. also vertikal verlegt, beispielsweise an Türkanten od. dgl., ist es möglich, die erforderliche Vorspannung, die zu dem Kontaktieren der Kontaktelemente miteinander führt, nur durch das Gewicht der Kontaktelemente herbeizuführen. Eine Solche Anordnung würde bei gleicher Sicherheit wie die bisher im Stand der Technik bekannten Anordnungen zu einer wesentlich kostengünstigeren Herstellungsweise führen, wobei dann aber der Innendurchmesser des Schlauches größer sein sollte als der Außendurchmesser der Kontaktelemente.If the safety bar is vertical, i.e. H. so laid vertically, for example on door edges or the like, it is possible to provide the required Bias leading to the contacting of the contact elements leads together, only by the weight of the contact elements bring about. Such an arrangement would be the same Security like the arrangements previously known in the prior art to a much cheaper way of manufacturing lead, but then the inner diameter of the Hose should be larger than the outside diameter of the Contact elements.

Bei der Ausführungsform gemäß Fig. 4 ist das Kontaktelement als Teilkugelelement 2b ausgebildet, das um eine Mittelachse X - X umlaufende Kontaktflächen 6 und 7 aufweist, die an den abgeflachten Seitenwänden 12 und 14 ausgebildet sind. Durch diese Anordnung wird eine größere Berührungsfläche als bei einer normalen Kugel geschaffen, so daß der elektrische Widerstand geringer ist und die Zentrierung verbessert wird. Es wird also insgesamt eine bessere Kontaktbildung erreicht. Das Kontaktelement 2b kann dabei so aufgebaut sein, daß eine leitfähige Hülse 8 vorgesehen ist, um die ein Mantel 9 aus Kunststoff gespritzt ist. Die Hülse 8 weist dabei planparallele Flächen 6 und 7 auf, die die Kontaktflächen 6 und 7 bilden.4 is the contact element formed as a partial spherical element 2b that around a central axis X - X has circumferential contact surfaces 6 and 7, which on the flattened side walls 12 and 14 are formed. By this arrangement will have a larger contact area than at a normal ball created so that the electrical resistance is less and the centering is improved. It will overall better contact formation. The contact element 2b can be constructed so that a conductive Sleeve 8 is provided, around which a jacket 9 is injection molded from plastic is. The sleeve 8 has plane-parallel surfaces 6 and 7 on, which form the contact surfaces 6 and 7.

Das in Fig. 4 dargestellte Kontaktelement 2b kann natürlich auch komplett aus leitfähigem Werkstoff gefertigt werden.The contact element 2b shown in FIG. 4 can of course also be made entirely of conductive material.
