Description

Die Erfindung betrifft eine Sicherheitsleiste nach dem Oberbegriff von Anspruch 1.The invention relates to a safety bar according to the preamble of claim 1.

Derartige Sicherheitsleisten sind aus dem Stand der Technik bekannt, beispielsweise aus der DE 196 47 720 A1. Bei der dort beschriebenen Sicherheitsleiste wird die Kontaktkette von einer Vielzahl von Kontaktelementen gebildet, welche längs der Sicherheitsleiste mittels einer Führungsvorrichtung aneinandergereiht sind und durch eine axiale Vorspannung längs der Sicherheitsleiste zusammengedrückt werden, wobei die Vorspannung durch manschettenförmige Schlauchstücke erzeugt wird, welche in alternierender Folge jeweils zwei zueinander benachbarte Kontaktelemente übergreifen und die Kontaktzonen dieser Kontaktelemente gegeneinander drücken. Diese Sicherheitsleiste kann kundenseitig auf einfache Art zusammengesetzt und den spezifischen Kundenbedürfnissen insbesondere hinsichtlich der Länge der Sicherheitsleiste individuell angepaßt werden, indem eine geeignete Anzahl von Kontaktelementen in einer Reihe angeordnet und mittels der Schlauchstücke miteinander verbunden werden. Die so gebildete Kontaktelementekette wird dann anschließend in einen elastischen Schlauch eingeführt, dessen stirnseitige Öffnungen schließlich durch Verschlußelemente abgedichtet werden, um die Schalteinrichtung vor Umwelteinflüssen und Feuchtigkeit zu schützen. Hierzu werden die Verschlußelemente mit dem elastischen Schlauch verklebt oder vulkanisiert. Dies hat sich als nachteilig erwiesen, weil nachträgliche Änderungen, insbesondere ein Kürzen der Sicherheitsleiste, nicht mehr möglich ist. Weiterhin hat es sich als problematisch erwiesen, Maßnahmen vorzusehen, welche den an den individuellen Bedürfnissen des Kunden ausgerichteten Zusammenbau einer Sicherheitsleiste in beliebiger Länge ermöglichen. Da die einzelnen Kontaktelemente eine vorgegebene Länge haben, war es bislang nur möglich, Sicherheitsleisten mit einer Länge zu fertigen, welche ein Vielfaches der Länge eines einzelnen Kontaktelements entspricht.Such safety strips are known from the prior art, for example from DE 196 47 720 A1. In the safety bar described there, the contact chain is from a plurality of contact elements formed, which along the security bar by means of a Guide device are strung together and by an axial preload along the Safety bar can be compressed, the preload through cuff-shaped pieces of hose is produced, which in alternating sequence each overlap two adjacent contact elements and the contact zones of these Press contact elements against each other. This safety bar can be opened by the customer simple type composed and the specific customer needs in particular can be individually adjusted with regard to the length of the safety bar by a suitable number of contact elements arranged in a row and by means of Pieces of tubing are connected together. The chain of contact elements thus formed becomes then then inserted into an elastic tube, the front openings finally be sealed by closure elements in front of the switching device Protect environmental influences and moisture. For this purpose, the closure elements with glued or vulcanized to the elastic hose. This has proven to be disadvantageous because subsequent changes, in particular shortening the safety bar, are no longer possible is possible. Furthermore, it has proven problematic to provide measures which is the assembly tailored to the individual needs of the customer allow a safety bar of any length. Because the individual contact elements have a predetermined length, it was previously only possible to use safety strips with a Length to produce, which is a multiple of the length of a single contact element equivalent.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Sicherheitsleiste zur Verfügung zu stellen, welche vor Ort auf einfache Art und an den jeweiligen individuellen Kundenbedürfnissen angepaßt zusammengebaut werden kann. The present invention is therefore based on the object of providing a safety bar To be made available on site in a simple manner and to the respective individual Can be assembled to meet customer needs.

Gelöst wird diese Aufgabe mit einer Sicherheitsleiste mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausfiihrungsbeispiele dieser Sicherheitsleiste sind den Unteransprüchen zu entnehmen.This problem is solved with a safety bar with the features of claim 1. Advantageous exemplary embodiments of this safety bar can be found in the subclaims remove.

Die perspektivische Darstellung der Figur 1 zeigt die Schalteinrichtung 1 einer Sicherheitsleiste zur Anordnung an Schließkanten bewegbarer Einrichtungen. Die Schalteinrichtung 1 umfaßt eine Kontaktelementekette 2, welche von einer Vielzahl von Kontaktelementen 2a, 2b, ......, 2x, 2y gebildet ist. Diese Kontaktelemente sind längs der Sicherheitsleiste linear aneinandergereiht. Jedes der Kontaktelemente 2a, 2b, ....., 2x, 2y weist einen elektrisch leitfähigen Kern auf. Dieser elektrisch leitfähige Bereich jedes Kontaktelements ist nach beiden Seiten mit dem jeweils benachbarten Kontaktelement 2b; 2a; ........., 2y; 2x elektrisch leitend verbunden. In einem Ruhezustand liegen die Kontaktelemente damit koaxial aneinandergereiht und stellen über die elektrisch leitfähigen Kernbereiche eine elektrisch leitfähige Verbindung zum jeweils benachbarten Kontaktelement und somit über die gesamte Sicherheitsleiste hinweg her.The perspective view of Figure 1 shows the switching device 1 one Safety bar for arrangement on closing edges of movable devices. The Switching device 1 comprises a contact element chain 2, which of a variety of Contact elements 2a, 2b, ......, 2x, 2y is formed. These contact elements are along the Safety bar lined up linearly. Each of the contact elements 2a, 2b, ....., 2x, 2y has an electrically conductive core. This electrically conductive area each Contact element is on both sides with the adjacent contact element 2b; 2a; ........., 2y; 2x electrically connected.

Zur Erzeugung einer axialen Vorspannung längs der Sicherheitsleiste werden die Kontaktelemente von Schlauchstücken 13a, 13b, ........., 13x, 13y an ihren Stirnseiten gegeneinander gedrückt. Die manschettenförmig ausgebildeten Schlauchstücke 13a, 13b, ......., 13x, 13y übergreifen jeweils die Endbereiche von zwei benachbarten Kontaktelementen 2a, 2b; 2x, 2x und drücken die Kontaktzonen an der Stirnseite der Kontaktelemente gegeneinander.To generate an axial preload along the safety bar, the Contact elements of hose pieces 13a, 13b, ........., 13x, 13y on their end faces pressed against each other. The sleeve-shaped hose pieces 13a, 13b, ......., 13x, 13y each overlap the end areas of two adjacent contact elements 2a, 2b; 2x, 2x and press the contact zones on the front of the contact elements up to today.

Bei äußerem Druck auf die Sicherheitsleiste wird die elektrische Verbindung zwischen benachbarten Kontaktelementen zumindest lokal gelöst. Die dadurch bedingte Unterbrechung der elektrischen Verbindung längs der Sicherheitsleiste wird dann durch eine hier nicht gezeigte Auswerteeinheit registriert, um dadurch beispielsweise den Kontakt der Sicherheitsleiste mit einem Hindernis zu registrieren.With external pressure on the safety bar, the electrical connection between neighboring contact elements at least locally solved. The resulting interruption the electrical connection along the safety bar is then not by one here shown evaluation unit registered to thereby, for example, the contact of the Register safety bar with an obstacle.

Die Schalteinrichtung 1 ist in einem in Figur 1 aus Gründen der besseren Darstellung nicht gezeigten elastischen Schlauch eingeführt. Die stirnseitigen Öffnungen dieses elastischen Schlauchs sind jeweils mit Verschlußelementen 3, 5 feuchtigkeitsdicht abgeschlossen. Die in Figur 1 gezeigten Verschlußelemente 3, 5 weisen eine Kabeldurchführung zum Herausführen eines Kontaktkabels 12 aus dem Schlauchinneren auf. Die Kabel 12 sind jeweils an einer Seite mit dem ersten Kontaktelement 2a bzw. dem letzten Kontaktelement 2y elektrisch verbunden und an der anderen Seite an die Auswerteeinheit angeschlossen.The switching device 1 is not in one in FIG. 1 for reasons of better illustration elastic hose shown introduced. The front openings of this elastic Hoses are each sealed moisture-tight with closure elements 3, 5. In the Figure 1 shown closure elements 3, 5 have a cable duct for leading out a contact cable 12 from the inside of the hose. The cables 12 are each on one Side with the first contact element 2a or the last contact element 2y electrical connected and connected to the evaluation unit on the other side.

Der Endbereich der Schalteinrichtung 1 ist in einer Schnittzeichnung in Figur 2 näher dargestellt. Dort ist das erste Kontaktelement 2a gezeigt. Dieses weist einen elektrisch leitfähigen Metallkern 16 und eine isolierende Kunststoff-Ummantelung 18 auf. Das in der Darstellung der Figur 2 linke Ende des Metallkerns 16 ist mit der stirnseitigen Kontaktzone des Metallkerns des benachbarten Kontaktelements 2b (in Figur 2 nicht mehr dargestellt) elektrisch leitend verbunden und an das in der Darstellung der Figur 2 rechte Ende des Metallkerns 16 ist das Kontaktkabel 12 angelötet. In der Figur 2 ist ferner der elastische Schlauch 4 gezeigt, in den die Kontaktelementekette 2 eingeführt ist. Die stirnseitige Öffnung des Schlauches 4 ist durch ein Verschlußelement 5 feuchtigkeitsdicht verschlossen. Das Verschlußelement 5 umfaßt einen topfförmigen Verschlußstopfen 7, dessen Wandung 9 in den Innenraum des Schlauches 4 eingreift und dessen Topfboden 14 die stirnseitige Öffnung des Schlauches 4 verschließt. In den Topfboden 14 des Verschlußstopfens 7 ist eine Kabeldurchführung 8 vorgesehen, um das Kontaktkabel 12 aus dem Schlauchinneren nach außen zu führen.The end region of the switching device 1 is closer in a sectional drawing in FIG. 2 shown. The first contact element 2a is shown there. This has an electrical conductive metal core 16 and an insulating plastic sheath 18. That in the Representation of Figure 2 left end of the metal core 16 is with the front contact zone of the metal core of the adjacent contact element 2b (no longer shown in FIG. 2) electrically connected and to the right in the illustration of Figure 2 end of Metal core 16, the contact cable 12 is soldered. In Figure 2 is also the elastic Hose 4 shown, in which the contact element chain 2 is inserted. The front opening the hose 4 is closed moisture-tight by a closure element 5. The Closure element 5 comprises a cup-shaped plug 7, the wall 9 in engages the interior of the hose 4 and the pot bottom 14 of the front opening the hose 4 closes. In the pot bottom 14 of the sealing plug 7 is one Cable bushing 8 is provided to the contact cable 12 from the inside of the hose to lead outside.

Das Verschlußelement 5 umfaßt ferner ein Distanzstück 6, welches zwischen dem Verschlußstopfen 7 und dem ersten Kontaktelement 2a angeordnet ist. Bei dem in der Figur 2 dargestellten Ausführungsbeispiel ist das Distanzstück 6 von einer ersten zylindrischen Distanzhülse 6a und einer diesbezüglich in Längsrichtung der Sicherheitsleiste verschieblich angeordneten zweiten zylindrischen Distanzhülse 6b gebildet. Die Länge des Distanzstücks 6 ist stufenlos zwischen einer Minimalstellung und einer Maximalstellung verstellbar, indem die beiden Distanzhülsen 6a, 6b gegeneinander verschoben werden. The closure element 5 further comprises a spacer 6, which between the Sealing plug 7 and the first contact element 2a is arranged. In the case of FIG The illustrated embodiment is the spacer 6 from a first cylindrical Spacer sleeve 6a and in this regard displaceable in the longitudinal direction of the safety bar arranged second cylindrical spacer sleeve 6b formed. The length of the spacer 6 is continuously adjustable between a minimum position and a maximum position by the two spacer sleeves 6a, 6b can be moved against each other.

Die Länge des Distanzstücks 6 kann dadurch bei der Montage der Sicherheitsleiste angepaßt werden, um die Gesamtlänge der Sicherheitsleiste den örtlichen Gegebenheiten entsprechend einzustellen.The length of the spacer 6 can thus be adjusted when installing the safety bar the total length of the safety bar according to local conditions adjust.

Die dem ersten Kontaktelement 2a zugewandte innere Distanzhülse 6b ist an ihrem einen Ende mit dem ersten Kontaktelement 2a fest verbunden. Die andere Distanzhülse 6a weist einen Innendurchmesser auf, welcher geringfügig größer ist als der Außendurchmesser der inneren Distanzhülse 6b, so daß diese Distanzhülse 6a als äußere Distanzhülse über die innere Distanzhülse 6b geschoben werden kann.The inner spacer sleeve 6b facing the first contact element 2a is at one of them End firmly connected to the first contact element 2a. The other spacer sleeve 6a has an inner diameter which is slightly larger than the outer diameter of the inner spacer 6b, so that this spacer 6a as an outer spacer over the inner Spacer sleeve 6b can be pushed.

Zur Fixierung einer gewünschten Länge des Distanzstücks 6 ist in der äußeren Distanzhülse 6a eine Bohrung 15 vorgesehen, in welche eine Madenschraube eingedreht werden kann, wodurch die relative Lage zwischen den Distanzhülsen 6a und 6b fixierbar ist.To fix a desired length of the spacer 6 is in the outer spacer sleeve 6a a bore 15 is provided into which a grub screw can be screwed, whereby the relative position between the spacer sleeves 6a and 6b can be fixed.
