Description

Gegenstand der Erfindung ist eine Schließkantensicherung für kraftbetätigte Türen, Tore oder dgl.The invention relates to a closing edge safety device for power-operated doors, gates or the like.

Für die Absicherung der Einzugsschlitze von aufwickelbaren Roll­gittern sind sogenannte Einziehsicherungen bekannt geworden, welche aus einem über die gesamte Torbreite gespannten Seil bestehen. Diese Seile müssen aber in einem großen Abstand vom Einzugsschlitz angeordnet werden, damit ein ausreichender Schaltweg zur Verfügung steht. Zur Minimierung dieses Schaltweges ist es erforderlich, das Seil straff zu spannen, damit es nicht durchhängt. Diese bekannte Einziehsicherung mit einem freigespannten Seil kann nicht als Schließkantensicherung am unteren Ende eines Rolltores angeordnet werden, weil das Tor dann nicht mehr vollständig schließen könnte.So-called retraction safeguards, which consist of a rope stretched over the entire door width, have become known for securing the pull-in slots of roll-up grilles that can be wound up. However, these ropes must be arranged at a large distance from the feed slot so that a sufficient switching path is available. To minimize this switching path, it is necessary to tighten the rope so that it does not sag. This known pull-in safety device with a free-stretched rope cannot be arranged as a closing edge safety device at the lower end of a roller door, because the door could then no longer close completely.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine einfach konstruierte Schließkantensicherung zu schaffen, die aus möglichst wenigen Einzelteilen besteht und deren elektrisches Schaltelement sich nicht im Betätigungs­bereich befindet.Proceeding from this, the object of the invention is to create a simply constructed closing edge safety device which consists of as few individual parts as possible and whose electrical switching element is not in the actuation area.

Als technische Lösung wird dafür ein mit einem elastisch verformbaren Körper abgestütztes, unelastisches Zugelement als Schaltglied vorgeschlagen. Dabei kann der elastisch verformbare Körper aus einem profilierten Schlauch bestehen, an dessen schließkantenseitiger Mantellinie ein in Längsrichtung verlaufendes Seil als Zugelement angeordnet ist.As a technical solution , an inelastic tension element supported as a switching element, which is supported with an elastically deformable body, is proposed. The elastically deformable body can consist of a profiled hose, on the closing edge-side surface line of which a rope running in the longitudinal direction is arranged as a tension element.

Eine nach dieser technischen Lehre ausgebildete Schließkanten­sicherung hat den Vorteil, daß wie bei der bekannten Einziehsicherung ein durchgehendes Seil als Schaltglied verwendet werden kann, welches störungsfrei arbeitet. Der Schaltweg des Seiles wird bezogen auf eine bestimmte Eindring­tiefe im Vergleich zu dem freigespannten Seil der bekannten Einziehsicherung durch die Abstützung mit dem elastisch verform­baren Körper sprunghaft vergrößert, wobei es unerheblich ist, ob der Schaltimpuls in der Mitte oder im Randbereich mit einem schmalen oder einem breiteren Gegenstand erzeugt wird. Weil das Seil nicht so stark wie bei der bekannten Einziehsicherung vorgespannt werden muß, ist die Betätigungskraft nicht viel größer als der Verformungswiderstand des elastisch verformbaren Schlauches.A closing edge safety device designed according to this technical teaching has the advantage that, as in the known pull-in safety device, a continuous rope can be used as the switching element, which works without problems. The switching path of the rope is increased in relation to a certain penetration depth in comparison to the free-stretched rope of the known retraction protection by the support with the elastically deformable body, it being irrelevant whether the switching pulse in the middle or in the edge area with a narrow or a wider one Object is generated. Because the rope does not have to be pre-tensioned as much as in the known pull-in protection, the actuating force is not much greater than the resistance to deformation of the elastically deformable hose.

Bei einer praktischen Ausführungsform kann das Profil des Schlauches schließkantenseitig konisch geformt und das Seil in eine Längsöffnung im Mantel des Schlauches eingezogen sein um die Empfindlichkeit der Schließkantensicherung zu verbessern.In a practical embodiment, the profile of the hose can be conically shaped on the closing edge side and the rope can be drawn into a longitudinal opening in the jacket of the hose in order to improve the sensitivity of the closing edge safety device.

Es ist aber auch möglich, das Seil in eine im Mantel des Schlauches angeordnete, nach außen offene Längsnut einzubetten. Wichtig ist dabei nur, daß sich das Seil nicht aus der Nut herausbewegen und durchhängen kann.However, it is also possible to embed the rope in a longitudinal groove which is arranged in the jacket of the hose and is open to the outside. It is only important that the rope cannot move out of the groove and sag.

Für die Nachrüstung wird vorgeschlagen, das Seil in einen außen auf den Schlauch geklebten engeren Schlauch einzuziehen.For retrofitting, it is proposed to pull the rope into a narrower hose glued to the outside of the hose.

Die Montage einer erfindungsgemäß ausgebildeten Schließkanten­sicherung kann in der Weise erfolgen, daß ein Ende des Seiles an einem Ende des Schlauches festgeklemmt ist und das andere Ende des Seiles aus dem Schlauch heraus zu einem elektrischen Schalter geführt ist, mit dem ein Antriebsmotor abschaltbar ist. Der Abstand zwischen Schlauch und Schalter kann dabei mit einem Kurvenstück oder auch einem Bowdenzug überbrückt werden. In dem Schalter kann ein mit dem Seil verbundener Stößel axial beweglich und federnd gelagert sein, der einen Mikroschalter mit Zwangstrennung betätigt.A closing edge safety device designed according to the invention can be installed in such a way that one end of the cable is clamped at one end of the hose and the other end of the cable is guided out of the hose to an electrical switch with which a drive motor can be switched off. The distance between the hose and the switch can be bridged with a curve section or a Bowden cable. A plunger connected to the cable can be axially inserted in the switch be movable and resilient, which operates a microswitch with forced separation.

Um die Schließkantensicherung selbstüberwachend, also auch einen Bruch des Seiles kontrollierend auszubilden, wird in weiterer Ausgestaltung der Erfindung vorgeschlagen, in dem Stößel eine umlaufende Schaltrinne mit konischen Flanken anzuordnen, in die ein Schaltstift des Mikroschalters eingreift. Das Seil kann dann durch eine Längsbohrung des Stößels geführt und mit Schrauben fixiert sein. Zwischen dem Stößel und dem Gehäuse des Schalters wird eine Druckfeder angeordnet, welche den Stößel bei einem Bruch des Seiles gegen den Schaltstift des Mikroschalters verschiebt.In order to design the closing edge safety device to be self-monitoring, that is to say to control breakage of the rope, it is proposed in a further embodiment of the invention to arrange a circumferential switching channel with conical flanks in the plunger, in which a switching pin of the microswitch engages. The rope can then be guided through a longitudinal bore of the ram and fixed with screws. A compression spring is arranged between the plunger and the housing of the switch, which pushes the plunger against the switching pin of the microswitch if the cable breaks.

Als Materialien für den Schlauch kommen Gummi oder Kunststoffe mit einer bestimmten Elastizität in Betracht, während das Seil aus einem biegsamen Material, beispielsweise aus einem Drahtseil oder aus Kunststoff bestehen kann.Materials for the hose are rubber or plastics with a certain elasticity, while the rope can be made of a flexible material, for example a wire rope or plastic.

Im Normalfall wird ein Seil als Schaltglied für die Schließkantensicherung ausreichen. Es ist aber insbesondere bei größeren Schlauchprofilen auch möglich, mehrere Seile im Abstand nebeneinander und parallel zueinander verlaufend in entsprechende Längsöffnungen im Mantel des Schlauches einzuziehen.Normally, a rope will be sufficient as a switching element for the closing edge safety device. However, it is also possible, in particular in the case of larger hose profiles, to pull in several cables at a distance from one another and parallel to one another into corresponding longitudinal openings in the jacket of the hose.

Mit dem in der Fig. 1 dargestellten Rolltor kann eine Toröffnung 1 verschlossen werden. Am unteren Ende eines Behanges 2 ist eine Schließkantensicherung 3 angeordnet, die im dargestellten Aus­führungsbeispiel gemäß den Fig. 2 und 3 aus einem elastisch verformbaren Schlauch 4 mit einem in eine Längsöffnung 5 eingezogenen Seil 6 besteht.A gate opening 1 can be closed with the roller door shown in FIG. 1. At the lower end of a curtain 2, a closing edge safety device 3 is arranged, which in the exemplary embodiment shown in FIGS. 2 and 3 consists of an elastically deformable hose 4 with a rope 6 drawn into a longitudinal opening 5.

Der Schlauch 4 ist an seinem oberen Rand mit einem Verankerungs­profil 7 in eine im Querschnitt C-förmige Profilschiene 8 eingezogen, mit der er am unteren Rand des Behanges 2 befestigt werden kann.The tube 4 is drawn at its upper edge with an anchoring profile 7 into a cross-sectionally C-shaped profile rail 8 with which it can be attached to the lower edge of the curtain 2.

An einem Ende des Schlauches 4 ist das Seil 6 in einem Kopfstück 9 fixiert, welches gleichzeitig in eine Führungsschiene 10 eingreift. Am anderen Ende ist das Seil 6 aus dem Schlauch 4 durch ein Kopfstück herausgeführt und durch eine Hülle 11 nach Art eines Bowdenzuges in ein Schaltergehäuse 12 hineingeführt, der auf dem Behang 2 befestigt ist.At one end of the hose 4, the cable 6 is fixed in a head piece 9, which at the same time engages in a guide rail 10. At the other end, the cable 6 is led out of the hose 4 through a head piece and through a sheath 11 in the manner of a Bowden cable into a switch housing 12 which is fastened on the curtain 2.

In dem Schalter 12 ist ein Stößel 13 mit einer umlaufenden Schaltrinne 14 axial verschiebbar angeordnet. Das Seil 6 ist durch eine Längsbohrung 15 des Stößels 13 geführt und mit Schrauben 16 fixiert. Zwischen dem Stößel 13 und dem Schalter­gehäuse 12 ist eine Druckfeder 17 angeordnet, die gleichzeitig zwei Funktionen erfüllt. Mit der Druckfeder 17 kann das Seil 6 über eine Einstellschraube 25 soweit vorgespannt werden, daß jeder Schaltimpuls an der Schließkante auch unmittelbar auf den Stößel 13 übertragen wird. Außerdem bewirkt die Druckfeder 17 bei einem Seilriß ebenfalls eine Verschiebung des Stößels 13, der in beiden Bewegungsrichtungen mit einem Schaltstift 18 eines Mikroschalters 19 zusammenwirkt.In the switch 12, a plunger 13 with a circumferential switching channel 14 is arranged axially displaceably. The rope 6 is guided through a longitudinal bore 15 of the plunger 13 and fixed with screws 16. Between the plunger 13 and the switch housing 12, a compression spring 17 is arranged, which simultaneously fulfills two functions. With the compression spring 17, the cable 6 can be prestressed via an adjusting screw 25 to such an extent that each switching pulse at the closing edge is also transmitted directly to the plunger 13. In addition, the compression spring 17 also causes a displacement of the plunger 13, which interacts in both directions of movement with a switching pin 18 of a microswitch 19 in the event of a cable break.

Aus dem Schaltplan der Fig. 7 ist ersichtlich, daß der Mikro­schalter 19 im Strompfad 20 für eine Schützspule 21 eines Motor­schützes für die Zu-Bewegung eines Antriebsmotors 22 liegt.7 that the microswitch 19 is located in the current path 20 for a contactor coil 21 of a motor contactor for the closing movement of a drive motor 22.

Durch die Abstützung des Seiles 6 an dem elastisch verformbaren Schlauch 4 ergeben sich im Falle eines Schaltimpulses an der Schließkante Einbuchtungen 23 mit verhältnismäßig steilen, unter einem Winkel von ca. 30° geneigten Flanken. Dabei ist die Neigung der Flanken von dem elastischen Verformungswiderstand des Schlauches 6 abhängig. Die Größe des Neigungswinkels bestimmt dabei die Länge des Schaltweges am Stößel 13 im Schaltergehäuse 12. Die Empfindlichkeit der Schließkanten­sicherung ist damit proportional zum Verformungswiderstand des Schlauchs
In der Praxis muß ein Kompromiß gesucht werden, denn der Verformungswiderstand des Schlauches darf einerseits nicht so groß sein, daß der Schlauch selbst Verletzungen verursachen kann, und darf andererseits nicht so niedrig sein, daß die Empfindlichkeit bzw. der Schaltweg am Stößel bei einem nennens­werten Schaltimpuls zu klein werden. Außerdem muß das Schlauch­profil eine Eindringtiefe von mehreren Zentimetern ermöglichen, weil der Antriebsmotor auch nach dem Abschalten noch einen Nachlauf hat.By supporting the cable 6 on the elastically deformable hose 4, in the event of a switching pulse, indentations 23 with relatively steep flanks which are inclined at an angle of approximately 30 ° result at the closing edge. The slope of the flanks depends on the elastic resistance to deformation of the hose 6. The size of the angle of inclination determines the length of the switching path on the plunger 13 in the switch housing 12. The sensitivity of the closing edge safety device is therefore proportional to the deformation resistance of the hose
In practice, a compromise must be sought, because the resistance to deformation of the hose must not be so great that the hose itself can cause injuries, and on the other hand it must not be so low that the sensitivity or the switching path on the plunger with a significant switching impulse get too small. In addition, the hose profile must allow a depth of penetration of several centimeters because the drive motor still has a run-on after it has been switched off.

Mit der schematischen Darstellung in der Fig. 6 soll veranschaulicht werden, daß die Empfindlichkeit einer erfindungsgemäß ausgebildeten Schließkantensicherung unabhängig davon ist, an welcher Stelle auf einer Länge von ca. 5 m ein Schaltimpuls mit einer Eindringtiefe von z.B. 50 mm erfolgt und ob die dabei erzeugte Einbuchtung 23 kurz oder lang ist. Bei den dargestellten Schaltimpulsen A, B und C wird in jedem Falle rechnerisch ein Schaltweg von ca. 20 mm am Stößel 13 erzeugt.The schematic representation in Fig. 6 is intended to illustrate that the sensitivity of a closing edge safety device according to the invention is independent of the point at which a switching pulse with a penetration depth of e.g. 50 mm takes place and whether the indentation 23 produced is short or long. In the switching pulses A, B and C shown, a switching path of approximately 20 mm is generated on the plunger 13 in any case.

Wäre das Seil 6 freitragend gespannt, so würde der Schaltweg nur ca. 1 mm betragen und damit noch im Bereich der durch Temperaturschwankungen bedingten Längenänderungen des Seiles 6 liegen. Dieser geringe Schaltweg wäre für eine zuverlässige Funktion der Schließkantensicherung nicht ausreichend.If the rope 6 were cantilevered, the switching path would only be approx. 1 mm and would therefore still be in the range of the length changes of the rope 6 caused by temperature fluctuations. This short switching path would not be sufficient for the closing edge safety device to function reliably.
