Abstract

The door-leaf (1) is movable into an overhead position, having rollers (2) working in guide rails (3). The electrical arrester (15) is incorporated in the rope, and is connected to the leaf-driving motor, which it switches off when the rope goes slack. The mechanical arrester (7) has one half of the leaf, and which engages with a stationary half on the rope going slack. The arresters are interconnected so that the electrical one operates first, followed by the mechanical one. With the rope taut, the spring-loaded leaf half can bear against a catch, which is released on the rope going slack.

Description

Die Erfindung betrifft eine Überwachungseinrichtung für ein Tragseil eines über Kopf bewegbaren, mit Rollen in Laufschienen geführten Torblattes.The invention relates to a monitoring device for a suspension cable of a door leaf which can be moved overhead and is guided by rollers in running rails.

Aus dem Stand der Technik sind derartige Überwachungseinrichtungen bekannt, bei denen ein Tragseil um eine Rolle im unteren Torblattbereich herum geführt ist. Das Tragseil ist auf der Torblattinnenseite befestigt, wobei das Tragseil um eine schwenkbare Sperrklinke geführt ist, die unter Federkraft gehalten wird. Bei Schlaffwerden des Tragseiles, wie es beispielsweise bei einem Seilbruch oder einem Federbruch einer die Wickelwelle für das Tragseil haltenden Torsionsfeder vorkommt, wird die Sperrklinke durch die sich entspannende Feder in Richtung auf die Laufschiene verschwenkt, wo die Sperrklinke entweder mit der Laufschiene oder einem anderen an der Laufschiene befestigten Element in Eingriff kommt. Hierbei handelt es sich demzufolge um rein mechanisch wirkende Fangeinrichtungen, die Bestandteil einer gattungsgemäßen Überwachungseinrichtung sind. Darüberhinaus sind aus dem Stand der Technik elektrische Fangeinrichtungen für Überwachungseinrichtungen bekannt, welche bei Schlaffwerden des Tragseils, beispielsweise bei Bruch der Gewichtsausgleichsfeder, bei Seilbruch, bei Anschlußbruch an Federbruch im Bereich des Getriebes des Antriebsmotors und dergleichen eine elektrische Abschaltung des Antriebsmotors bewirken.Monitoring devices of this type are known from the prior art, in which a support cable is guided around a roller in the lower door leaf area. The suspension cable is attached to the inside of the door leaf, the suspension cable being guided around a pivotable pawl which is held under spring force. If the suspension cable becomes slack, as occurs, for example, in the event of a cable break or a spring break in a torsion spring holding the winding shaft for the suspension cable, the pawl is pivoted by the relaxing spring in the direction of the running rail, where the pawl either touches the running rail or another the track attached element comes into engagement. Accordingly, these are purely mechanical safety devices that are part of a generic monitoring device. In addition, electrical safety devices for monitoring devices are known from the prior art, which cause the drive motor to be electrically switched off when the suspension cable becomes slack, for example when the counterbalance spring breaks, when the cable breaks, when the spring breaks in the area of the transmission of the drive motor and the like.

Die voranstehend beschriebenen Überwachungseinrichtungen der gattungsgemäßen Art gemäß dem Stand der Technik haben sich für eine Schlaffseilsicherung eines über Kopf bewegbaren Torblattes bewährt.The above-described monitoring devices of the generic type according to the prior art have proven themselves for securing slack rope of a door leaf which can be moved overhead.

Ausgehend von dem voranstehend beschriebenen Stand der Technik ist es Aufgabe der Erfindung, eine gattungsgemäße Überwachungseinrichtung derart weiterzubilden, daß einerseits ein sicheres Abfangen des sich plötzlich in die Schließstellung bewegenden Torblattes ermöglicht wird, wobei andererseits jedoch die Überwachungseinrichtung, Fangeinrichtungen aufweisen soll, die in Abhängigkeit des zum Absturz des Torblattes führenden Schadens aktiviert werden.Based on the prior art described above, it is an object of the invention to develop a generic monitoring device such that, on the one hand, safe interception of the door leaf that suddenly moves into the closed position is made possible, but on the other hand, the monitoring device should have catching devices which, depending on the damage causing the door leaf to crash can be activated.

Die Lösung dieser Aufgabenstellung sieht bei einer gattungsgemäßen Überwachungseinrichtung eine elektrische Fangeinrichtung, die in das Tragseil eingeschaltet und mit einem Antriebsmotor für die Bewegung des Torblattes verbunden ist, welcher durch die elektrische Fangeinrichtung bei Schlaffseil abschaltbar ist, und eine mechanische Fangeinrichtung vor, die ein am Torblatt angeordnetes Fangglied aufweist, welches bei Schlaffseil mit einem relativ zum Torblatt feststehenden Element das Torblatt fangend zur Anlage kommt, wobei die elektrische Fangeinrichtung und die mechanische Fangeinrichtung derart in Reihe geschaltet sind, daß zunächst die elektrische und dann die mechanische Fangeinrichtung anspricht.The solution to this problem is provided in a generic monitoring device, an electrical safety device that is switched into the suspension cable and connected to a drive motor for the movement of the door leaf, which can be switched off by the electrical safety device for slack rope, and a mechanical safety device that a on the door leaf Arranged catch member, which catches the door leaf with slack rope with a fixed element relative to the door leaf, the electrical safety device and the mechanical safety device are connected in series such that the electrical and then the mechanical safety device responds.

Eine erfindungsgemäß ausgebildete Überwachungseinrichtung für ein Tragseil eines über Kopf bewegbaren, mit Rollen in Laufschienen geführten Torblattes sieht somit eine Zwangsfolge vor, derart, daß zunächst die elektrische Fangeinrichtung anspricht und den Antriebsmotor abschaltet, der aufgrund von Selbsthemmung des Motorausgangsgetriebes das sich in die Schließstellung bewegende Torblatt abfangen kann, so daß es im Zweifelsfall unnötig ist, die mechanische Fangeinrichtung auszulösen. Bricht beispielsweise eine Feder und das Tragseil wird kurzzeitig schlaff, dann spricht die elektrische Fangeinrichtung an und schaltet den Motor ab, der dann aufgrund des sich nach unten bewegenden Torblattes bei Motorstillstand das Tragseil wieder spannt, so daß die mechanische Fangeinrichtung nicht ausgelöst wird.A monitoring device designed according to the invention for a suspension cable of a door leaf that can be moved overhead and is guided by rollers in running rails thus provides a compulsory sequence, such that the electrical safety device responds first and switches off the drive motor, which, due to self-locking of the motor output gearbox, causes the door leaf to move into the closed position can intercept, so that in case of doubt it is unnecessary to trigger the mechanical safety gear. If, for example, a spring breaks and the suspension cable becomes slack for a short time, the electrical safety device responds and switches off the motor, which then tensions the suspension cable again when the engine is at a standstill due to the door leaf moving downwards, so that the mechanical Safety gear is not triggered.

In den Fällen, wenn der vorgeschilderte Vorgang, d.h. daß Spannen des Tragseiles durch die Arretierung des Antriebsmotoraggregates, nicht schnell genug erfolgt, oder das Tragseil reißt, muß das Torblatt mechanisch abgefangen werden. Es wird dann nach der elektrischen Fangeinrichtung, die eine Schlaffseilüberwachung aufweist, in Folge die mechanische Fangeinrichtung ausgelöst. Zu diesem Zweck sind die elektrische Fangeinrichtung und die mechanische Fangeinrichtung in das Tragseil insoweit in Reihe geschaltet. Die in den Tragseilverlauf eingeschaltete mechanische Fangeinrichtung arbeitet vorzugsweise mit einer unter Federvorspannung stehenden Klinke derart, daß die die Klinke betätigende Feder vorgespannt ist. Bei Schlaffwerden des Tragseils wird die Klinke unter der ihr? zugeordneten Federkraft verschwenkt und gibt dabei ein um eine Achse drehbares Fangglied frei, das unter der Kraft wiederum einer Feder, insbesondere einer Winkelfeder, in die Fangrichtung verschwenkt wird.In cases when the described process, i.e. The door leaf must be mechanically intercepted to prevent the suspension cable from being tensioned quickly enough by locking the drive motor unit, or the suspension cable to break. The mechanical safety device is then triggered after the electrical safety device, which has slack rope monitoring. For this purpose, the electrical safety device and the mechanical safety device are connected in series in the supporting cable. The mechanical catching device switched on in the course of the supporting cable preferably works with a spring-loaded pawl such that the spring actuating the pawl is pretensioned. If the suspension cable becomes slack, the pawl will be under yours? assigned spring force pivoted and thereby releases a catch member rotatable about an axis, which in turn is pivoted in the catch direction under the force of a spring, in particular an angle spring.

Vorzugsweise ist an dem rotierenden Fangglied eine scharfkantige Stahlschneide angeordnet, die auf eine Außenwölbung der Laufschiene auftrifft und durch das Gewicht des sich in die Schließstellung bewegenden Torblattes in das Laufschienenblech eingedrückt wird. Der Eingriff geschieht dabei insoweit formschlüssig, wobei die mit ihrer Schneide schräg nach unten gerichtete Stahlschneide unter der Kraft der Feder des Fanggliedes an das Laufschienenblech angedrückt wird.A sharp-edged steel cutting edge is preferably arranged on the rotating catch element, which strikes an outer curvature of the running rail and is pressed into the running rail plate by the weight of the door leaf moving into the closed position. The intervention takes place in this respect in a form-fitting manner, the steel cutting edge, which is directed obliquely downward with its cutting edge, being pressed against the running track plate under the force of the spring of the catching element.

Bei der erfindungsgemäßen Überwachungseinrichtung ist demzufolge von besonderer Bedeutung die Reihenschaltung der elektrischen Fangeinrichtung einerseits und der mechanischen Fangeinrichtung andererseits und zwar mit der Zwangsfolge, daß zunächst die elektrische Fangeinrichtung und dann die mechanische Fangeinrichtung anspringt.In the monitoring device according to the invention, the series connection of the electrical safety device on the one hand and the mechanical safety device on the other hand is therefore of particular importance, with the constraint that first the electrical safety device and then the mechanical safety device starts.

Vorzugsweise wird diese Zwangsfolge durch ein Schlaffseilsicherungselement erreicht, das Bestandteil der elektrischen Fangeinrichtung ist, wobei das Schlaffseilsicherungselement die Tragseilspannung misst und bei Schlaffwerden des Tragseils das Tragseil zunächst straff hält, so daß die reduzierte Tragseilspannung über einen bestimmten Zeitraum nicht auf die nachgeschaltete mechanische Fangeinrichtung übertragen wird. Wird in diesem vorbestimmten Zeitraum die erforderliche Tragseilspannung nicht wieder aufgebaut, so wird die reduzierte Tragseilspannung auf die nachgeschaltete mechanische Fangeinrichtung übertragen, so daß diese ausgelöst und das Torblatt abgefangen wird.This constraint sequence is preferably achieved by a slack rope securing element which is part of the electrical catching device, the slack rope securing element measuring the suspension rope tension and when the slackening Carrier rope initially holds the suspension rope taut so that the reduced suspension rope tension is not transmitted to the downstream mechanical safety gear over a certain period of time. If the required suspension cable tension is not re-established within this predetermined period of time, the reduced suspension cable tension is transmitted to the downstream mechanical catching device so that it is triggered and the door leaf is intercepted.

Vorzugsweise ist das Tragseil über eine Rolle am unteren Randbereich des Torblattes geführt und zwischen der elektrischen Fangeinrichtung und der mechanischen Fangeinrichtung eine Umlenkrolle für das Tragseil angeordnet. Durch diese konstruktive Ausgestaltung können die elektrische Fangeinrichtung und die mechanische Fangeinrichtung am Torblatt auf relativ begrenzter Fläche nebeneinander angeordnet werden, ohne daß die Wirkungsweisen der beiden Fangeinrichtungen gegenseitig nachteilig beeinflußt werden.The supporting cable is preferably guided over a roller at the lower edge region of the door leaf and a deflection roller for the supporting cable is arranged between the electrical catching device and the mechanical catching device. As a result of this design, the electrical catching device and the mechanical catching device can be arranged next to one another on the door leaf on a relatively limited area without the effects of the two catching devices being adversely affected.

Es hat sich ferner als vorteilhaft erwiesen, die Umlenkrolle vertikal verschiebbar am Torblatt zu befestigen, so daß einerseits über diese Umlenkrolle die Spannung des Tragseils eingestellt werden kann und andererseits die Umlenkrolle zum Auslösen der mechanischen Fangeinrichtung genutzt werden kann.It has also proven to be advantageous to fasten the deflecting roller vertically displaceably on the door leaf, so that on the one hand the tension of the supporting cable can be adjusted via this deflecting roller and on the other hand the deflecting roller can be used to trigger the mechanical catching device.

Wie voranstehend ausgeführt, soll zunächst der Antriebsmotor abgeschaltet werden, wodurch je nach Schadensfall das Torblatt durch den Stillstand des Antriebsmotors gehalten wird. Erst wenn hierdurch eine Weiterbewegung des Torblattes in Richtung auf die Schließstellung nicht ausgeschlossen wird, tritt die mechanische Fangeinrichtung in Kraft. Die mechanische Fangeinrichtung ist dann derart ausgebildet, daß sie nicht durch erneute Inbetriebnahme des Antriebsmotors aus ihrer Fangstellung herausgeschwenkt werden kann. Vielmehr ist es hierzu notwendig, daß die mechanische Fangeinrichtung erst nach Behebung sämtlicher aufgetretener Fehler wieder in die Wartestellung, also außer Eingriff mit der Laufschiene, insbesondere von Hand, überführt werden kann.As stated above, the drive motor should first be switched off, so that depending on the damage, the door leaf is held by the drive motor being at a standstill. Only if this does not preclude further movement of the door leaf in the direction of the closed position does the mechanical catching device come into effect. The mechanical catching device is then designed in such a way that it cannot be swiveled out of its catching position by restarting the drive motor. Rather, it is necessary for this that the mechanical catching device can only be brought back to the waiting position, ie out of engagement with the running rail, in particular by hand, after all errors that have occurred have been eliminated.

In anderer bevorzugter Ausführung ist das Fangglied als Fangexzenter ausgebildet, hinsichtlich eines Scheibenumfanges also exzentrisch drehgelagert, und in seinem an dem feststehenden Gegenstand, vorzugsweise der Laufschiene, mit wenigstens einem etwa radial zur Drehachse, vorzugsweise spitzzahnartig, abragenden Vorsprung versehen, der im Fangfall unter Federkraft in Anlage an den Gegenstand verschwenkt wird und sich unter dem Gewicht des sich in die Schließstellung bewegenden Torblattes in eine Fläche des feststehenden Gegenstandes, vorzugsweise einer Außenwölbung der Laufschiene, eindrückt. Im übrigen sind die Bauteile dieser anderen Ausführungsform mit denen des vorstehend geschilderten Beispieles zumindest weitgehend funktionsgleich.In another preferred embodiment, the catch element is designed as a catch eccentric, that is to say is eccentrically rotatably mounted with respect to a disk circumference, and provided on the fixed object, preferably the running rail, with at least one projection projecting approximately radially to the axis of rotation, preferably pointed tooth-like, which is pivoted under spring force into contact with the object and moves under the weight of the door leaf moving into the closed position presses a surface of the stationary object, preferably an outer curvature of the running rail. Otherwise, the components of this other embodiment are at least largely functionally identical to those of the example described above.

In besonders bevorzugter Ausführung ist dieses andere Ausführungsbeispiel mit einem dem exzentrischen Fangglied zugeordneten Blockierglied versehen, dessen Gestalt vorzugsweise etwa spiegelbildlich demjenigen des Fanggliedes entspricht. Der an dem Blockierglied in vergleichbarer Weise angeordnete wenigstens eine Vorsprung dient bei ausgelöstem Fangzustand und damit Angriff an den feststehenden Gegenstand, insbesondere Laufschiene, dazu, daß das in der Fangstellung befindliche Torblatt nicht durch unbefugten oder ungewollten Angriff in Richtung Offenstellung verschoben werden kann; es handelt sich bei diesem Blockierglied im Fangfall also um eine Aufschubsicherung für das Torblatt. Die hier geschilderte Funktion ist grundsätzlich mit nur einem geradlinig vorstehendem Vorsprung möglich, wenn der Angriff an dem ortsfesten Gegenstand entsprechend weit vor Erreichen des Totpunktes im Rahmen der jeweiligen Drehbewegung der beiden Exzenter stattfindet. In bevorzugter Ausführung sind das Fangglied und das Blockierglied jeweils mit Vorsprüngen versehen, die hinsichtlich des Fanggliedes aus der Radialen in die Schließstellung und hinsichtlich des Blockiergliedes in die Öffnungsstellung des Torblattes geneigt ausgebildet sind, wie dies aus Figur 5 des Ausführungsbeispieles ersichtlich ist.In a particularly preferred embodiment, this other exemplary embodiment is provided with a blocking member assigned to the eccentric catching member, the shape of which preferably corresponds approximately to that of the catching member in a mirror image. The at least one projection arranged in a comparable manner on the blocking member is used when the catch condition is triggered and thus attacking the fixed object, in particular running track, in such a way that the door leaf in the catching position cannot be moved in the direction of the open position by unauthorized or unwanted attack; in the event of a fall, this blocking member is therefore a deferral device for the door leaf. The function described here is fundamentally possible with only a straight protrusion if the attack on the stationary object takes place far before reaching the dead center as part of the respective rotary movement of the two eccentrics. In a preferred embodiment, the catch member and the blocking member are each provided with projections which are inclined with respect to the catch member from the radial to the closed position and with respect to the blocking member into the open position of the door leaf, as can be seen from FIG. 5 of the exemplary embodiment.

Bei Betätigen des Auslösegliedes bewegen sich Fangexzenter und Blockierexzenter in die Eingriffsdrehstellung, was besonders bevorzugt dadurch synchron geschieht, daß die Bewegung des einen Exzenters von derjenigen des anderen Exzenters abgeleitet ist. Bevorzugt wird durch das Auslöseglied einer der Exzenter, insbesondere der Fangexzenter, der unter Federvorspannung steht, in seine Eingriffstellung bewegt, wobei aufgrund einer getrieblichen Verbindung zwischen beiden Exzentern diese Drehbewegung gegensinnig auf den anderen Exzenter übertragen wird. Zu diesem Zwecke sind bevorzugt das Fangglied und das Blockierglied auf etwa parallelen Achsen angeordnet und mit jeweils etwa peripher über einen Teilumfangsbereich gegendrehsinnig an die jeweiligen spitzzahnartigen Vorsprünge anschließend ausgebildeten Verzahnungen versehen, die getrieblich ineinandergreifen.When the trigger member is actuated, the catch eccentric and the blocking eccentric move into the rotational engagement position, which is particularly preferably done synchronously in that the movement of one eccentric is derived from that of the other eccentric. Preferably, one of the eccentrics, in particular the catch eccentric, which is under spring preload, is moved into its engagement position by the triggering member, due to a gear connection between the two eccentrics this rotational movement is transmitted in opposite directions to the other eccentric. For this purpose, the catch member and the blocking member are preferably arranged on approximately parallel axes and are each provided with toothings which are formed approximately peripherally over a partial circumferential region in the opposite direction to the respective pointed tooth-like projections and which mesh with one another in a geared manner.

In der Figur 1 ist schematisch ein Torblatt 1 dargestellt, welches in Schließstellung in seinem unteren Seitenkantenbereich jeweils eine Laufrolle 2 hat, die in jeweils einer Laufschiene 3 geführt sind, welche in vertikaler Richtung verlaufen. Die Laufrollen 2 sind über Achsstummel 4 mit dem Torblatt 1 verbunden. Die Laufschienen 3 sind an Zargenteilen 5 befestigt, welche ihrerseits innerhalb einer Gebäudeöffnung an in den Figuren nicht dargestelltem Mauerwerk angeordnet sind.A door leaf 1 is shown schematically in FIG. 1, which in the closed position has a roller 2 in its lower side edge region, each of which is guided in a running rail 3, which run in the vertical direction. The rollers 2 are connected to the door leaf 1 via stub axle 4. The rails 3 are fastened to frame parts 5, which in turn are arranged within a building opening on masonry, not shown in the figures.

Auf der Innenseite des Torblattes 1 ist ein Träger 6 angeordnet, welcher eine mechanische Fangeinrichtung 7 aufweist, die nachfolgend noch detailliert beschrieben wird. Der Träger 6 ist plattenförmig ausgebildet und weist an seinen Schmalseiten abgeknickte Seitenstege 8 auf, die im wesentlichen parallel zueinander verlaufen und im wesentlichen im rechten Winkel zur Innenfläche des Torblattes 1 angeordnet sind.A carrier 6 is arranged on the inside of the door leaf 1 and has a mechanical catching device 7, which will be described in detail below. The carrier 6 is plate-shaped and has on its narrow sides kinked side webs 8 which run essentially parallel to one another and are arranged essentially at right angles to the inner surface of the door leaf 1.

Die mechanische Fangeinrichtung 7 weist eine Klinke 9 auf, die über eine Bolzenverbindung 10 schwenkbeweglich an einem Seitensteg 8 des Trägers 6 befestigt ist. Die Klinke 9 ist an ihrem einen, dem Träger 6 abgewandten Ende über ein Befestigungselement 11 mit einem Tragseil 12 verbunden, welches mit seinen dem Befestigungselement 11 abgewandten Ende an einer nicht dargestellten, mittels einer Torsionsfeder vorgespannten Welle befestigt ist. Das Tragseil läuft hierzu ausgehend von dem Befestigungselement 11 über eine Umlenkrolle 13 und eine Umlenkung 14, die vorzugsweise als Rolle ausgebildet und zwischen der Laufrolle 2 und der dieser Laufrolle 2 zugewandten Seitenkante des Torblattes 1 angeordnet ist. Das Tragseil 12 läuft somit zumindest mit einem Teilbereich etwa parallel zum Zargenteil 5.The mechanical catching device 7 has a pawl 9 which is fastened to a side web 8 of the carrier 6 so that it can pivot about a bolt connection 10. The pawl 9 is connected at its one end facing away from the carrier 6 via a fastening element 11 to a supporting cable 12 which is fastened with its end facing away from the fastening element 11 to a shaft (not shown) which is pretensioned by means of a torsion spring. For this purpose, the supporting cable runs from the fastening element 11 via a deflection roller 13 and a deflection 14, which is preferably designed as a roller and is arranged between the roller 2 and the side edge of the door leaf 1 facing this roller 2. The support cable 12 thus runs at least with a partial area approximately parallel to the frame part 5.

Die Umlenkrolle 13 ist parallel zur die Umlenkung 14 aufweisenden Seitenkante des Torblattes 1 verschiebbar am Torblatt 1 befestigt, so daß beispielsweise mittels der Umlenkrolle 13 eine vorbestimmte Spannung im Tragseil 12 eingestellt werden kann, bzw. aufrechterhalten wenn bei Schlaffwerden des Seiles zunächst die Seilspannung mittels einer elektrischen Fangeinrichtung (15) abgetastet wird.The deflection roller 13 is slidably attached to the door leaf 1 parallel to the deflection 14 having the side edge of the door leaf 1, so that for example by means of the deflection roller 13 a predetermined tension in the supporting rope 12 can be set, or maintained when the rope first slackens the rope tension by means of a electrical safety device (15) is scanned.

Zwischen der Umlenkrolle 13 und der Umlenkung 14 ist diese elektrische Fangeinrichtung 15 in das Tragseil 12 eingeschaltet, welche über ein Kabel 16 mit einem nicht dargestellten Antriebsmotor verbunden ist.Between the deflection roller 13 and the deflection 14, this electrical catching device 15 is switched into the support cable 12, which is connected via a cable 16 to a drive motor, not shown.

Wie insbesondere aus der Figur 3 zu erkennen ist, weist die Klinke 9 eine parallel zur Flächennormalen des Torblattes 1 ausgerichtete Bohrung 17 auf, in welche eine Feder 18 eingesetzt ist, die sich mit einem Ende auf dem Träger 6 abstützt, wobei die Feder 18 bei gespanntem Tragseil 12 vorgespannt ist. Die im wesentlichen L-förmig ausgebildete Klinke 9 ist um einen durch die Bolzenverbindung 10 dargestellten Drehpunkt drehbar gelagert, wobei sich die Klinke 9 an ihrem dem Befestigungselement 11 gegenüberliegenden Ende an einem schwenkbaren Fangglied 19 abstützt, welches um eine Schwenkachse 20 verschwenkbar ist, wobei die Schwenkachse 20 parallel zu der durch die Bolzenverbindung 10 gebildete Schwenkachse verläuft. Das Fangglied 19 weist einen Absatz 21 auf, der mit der Klinke 9 zusammenwirkt.As can be seen in particular from FIG. 3, the pawl 9 has a bore 17 aligned parallel to the surface normal of the door leaf 1, into which a spring 18 is inserted, which is supported at one end on the carrier 6, the spring 18 being shown in FIG tensioned suspension cable 12 is biased. The essentially L-shaped pawl 9 is rotatably mounted about a pivot point represented by the bolt connection 10, the pawl 9 being supported at its end opposite the fastening element 11 on a pivotable catch member 19 which is pivotable about a pivot axis 20, the Pivot axis 20 runs parallel to the pivot axis formed by the bolt connection 10. The catch member 19 has a shoulder 21 which interacts with the pawl 9.

In der Figur 3 ist die Ausgangsstellung der Klinke 9 und des Fanggliedes 19 bei gespanntem Tragseil 12 durch ausgezogene Linien dargestellt, wogegen die strichpunktierten Linien in der Figur 3 die Stellung der Klinke 9 und des Fanggliedes 19 bei schlaffem Tragseil 12 darstellt.In Figure 3, the starting position of the pawl 9 and the catch member 19 is shown by the solid lines with the tensioned rope 12, whereas the dash-dotted lines in Figure 3 represents the position of the pawl 9 and the catch member 19 when the suspension rope 12 is slack.

An dem Fangglied 19 ist, wie es in Figur 2 dargestellt ist, eine Schneide 22 aus Stahl befestigt, die in Richtung auf die Laufschiene 3 ausgerichtet ist und sich bei schlaffem Tragseil 12 durch das Gewicht des sich in die Schließstellung bewegenden Torblattes 1 in die Laufschiene 3 eingräbt, so daß die Schneide 22 bei aktivierter mechanischer Fangeinrichtung 7 eine formschlüssige Verbindung mit der Laufschiene 3 herstellt, die ein weiteres Abstürzen des Torblattes 1 verhindert.On the catch member 19, as shown in FIG. 2, a cutting edge 22 made of steel is fastened, which is oriented in the direction of the running rail 3 and, when the carrying cable 12 is slack, by the weight of the door leaf 1 moving into the closed position into the running rail 3 digs in, so that the cutting edge 22 produces a positive connection with the running rail 3 when the mechanical catching device 7 is activated, which prevents the door leaf 1 from falling further.

Um eine sichere Auslösung des schwenkbaren Fanggliedes 19 zu ermöglichen, ist das Fangglied 19 mit einer nicht näher dargestellten Feder - vorzugsweise Schenkelfeder - verbunden, die das Fangglied 19 um die Schwenkachse 20 verdreht, wenn die Klinke 9 außer Eingriff mit dem Absatz 21 gerät.In order to enable safe triggering of the pivotable catch element 19, the catch element 19 is connected to a spring (preferably leg spring), which is not shown in any more detail and which rotates the catch element 19 about the pivot axis 20. if the pawl 9 disengages from the paragraph 21.

Die voranstehend beschriebene Überwachungseinrichtung für das Tragseil 12 des über Kopf bewegbaren, mit Laufrollen 2 in Laufschienen 3 geführten Torblattes 1 weist demzufolge zwei in Reihe geschaltete Fangeinrichtungen 7, 15 auf, wobei die elektrische Fangeinrichtung 15 anspricht und den nicht dargestellten Antriebsmotor abschaltet, wenn das Tragseil 12 schlaff wird. In diesem Fall besteht die Möglichkeit, daß aufgrund der Selbsthemmung des Motorausgangsgetriebes das Torblatt 1 abgefangen wird, so daß das Tragseil 12 sich spannt. Zu diesem Zweck weist die elektrische Fangeinrichtung 15 ein nicht dargestelltes Schlaffseilsicherungselement auf, welches die Spannung des Tragseils 12 misst und bei Schlaffwerden des Tragseils 12 das Tragseil 12 zunächst straff hält, so daß die reduzierte Tragseilspannung über einen bestimmten Zeitraum nicht auf die nachgeschaltete mechanische Fangeinrichtung 7 übertragen wird. Demzufolge wird bei kurzfristig schlaffem Tragseil 12 lediglich die elektrische Fangeinrichtung 15 aktiviert, wogegen die mechanische Fangeinrichtung 7 in nicht aktiviertem Zustand verbleibt.The above-described monitoring device for the suspension cable 12 of the door leaf 1, which can be moved overhead with guide rollers 2 in rails 3, accordingly has two safety devices 7, 15 connected in series, the electrical safety device 15 responding and switching off the drive motor (not shown) when the suspension cable 12 goes limp. In this case, there is the possibility that the door leaf 1 is intercepted due to the self-locking of the motor output transmission, so that the supporting cable 12 is tensioned. For this purpose, the electrical safety device 15 has a slack rope securing element, not shown, which measures the tension of the suspension cable 12 and initially keeps the suspension rope 12 taut when the suspension cable 12 becomes slack, so that the reduced suspension cable tension does not affect the downstream mechanical safety device 7 for a certain period of time is transmitted. Accordingly, only the electrical safety device 15 is activated when the suspension cable 12 is slack for a short time, whereas the mechanical safety device 7 remains in the non-activated state.

Diese Funktionsweise ist dann gegeben, wenn beispielsweise eine von zwei Federn bricht, welche die Wickelwelle unter Spannung halten, so daß nur kurzfristig das Tragseil 12 schlaff wird.This mode of operation is given when, for example, one of two springs breaks, which keep the winding shaft under tension, so that the suspension cable 12 only slackens briefly.

In anderen Fällen, wenn der voranstehend geschilderte Vorgang des kurzzeitigen Schlaffwerdens des Tragseils 12 über einen gewissen Zeitraum anhält, beispielsweise wenn ein Tragseil 12 reißt, muß das Torblatt 1 mittels der mechanischen Fangeinrichtung 7 abgefangen werden, um ein Absturz des Torblattes 1 zu verhindern. In diesem Fall wird nach der elektrischen Fangeinrichtung 15 die mechanische Fangeinrichtung 7 ausgelöst, d.h. die Klinke 9 wird mittels der Feder 18 um die Bolzenverbindung 10 verschwenkt, so daß sie außer Eingriff mit dem Absatz 21 des Fanggliedes 19 gelangt. Hierdurch verdreht eine nicht dargestellte, vorgespannte Feder das Fangglied 19 um die Schwenkachse 20, wodurch die Schneide 22 des Fanggliedes 19 in Richtung auf die Laufschiene 3 verschwenkt und sich in diese formschlüssig eingräbt. Als Feder für das Fangglied 19 ist vorzugsweise eine Winkelfeder vorgesehen.In other cases, if the above-described process of the suspension rope 12 temporarily falling asleep for a certain period of time, for example if a suspension rope 12 breaks, the door leaf 1 must be intercepted by means of the mechanical catching device 7 in order to prevent the door leaf 1 from falling. In this case, the mechanical safety device 7 is triggered after the electrical safety device 15, ie the pawl 9 is pivoted about the bolt connection 10 by means of the spring 18, so that it disengages from the shoulder 21 of the safety element 19. As a result, a preloaded spring (not shown) rotates the catch element 19 about the pivot axis 20, as a result of which the cutting edge 22 of the catch element 19 pivots in the direction of the running rail 3 and digs into it in a form-fitting manner. As a spring for the catch member 19, an angle spring is preferably provided.

Die scharfkantige Schneide 22 greift vorzugsweise auf die Außenwölbung der Laufschiene 3, wobei das Eingreifen möglichst gegenüber einer Laufrolle 2 erfolgt, so daß ausreichender Gegendruck auf die Laufschiene 3 ausgeübt wird, der ein, das Einrasten der Schneide 2 verhinderndes Ausweichen der Laufschiene 3 behindert.The sharp-edged cutting edge 22 preferably engages on the outer curvature of the running rail 3, the engagement taking place as far as possible with respect to a running roller 2, so that sufficient counter pressure is exerted on the running rail 3, which prevents the running rail 3 from evading to prevent the cutting edge 2 from snapping into place.

Bei der erfindungsgemäßen und voranstehend beschriebenen Überwachungseinrichtung ist wesentlich die Reihenschaltung der elektrischen Fangeinrichtung 15 vor der mechanischen Fangeinrichtung 7, so daß eine Zwangsfolge der beiden Fangeinrichtungen 7 und 15 gegeben ist, die zunächst die elektrische Fangeinrichtung 15 und dann die mechanische Fangeinrichtung 17 auslöst. Die mechanische Fangeinrichtung 7 ist darüberhinaus derart ausgebildet, daß nach ihrem Auslösen eine erneute Inbetriebnahme bzw. Bewegung des Torblattes 1 durch den nicht dargestellten Antriebsmotor aus der Fangstellung heraus nicht möglich ist. Die mechanische Fangeinrichtung 7 muß vielmehr ganz gezielt nach Behebung sämtlicher aufgetretener Fehler wieder in ihre Wartestellung, also außer Eingriff mit der Laufschiene 3, überführt werden. Diese Überführung geschieht in der Regel per Hand, so daß sichergestellt ist, daß ein Anfahren des Antriebsmotors vor Behebung aller Fehlerquellen unmöglich ist. Es kann darüberhinaus vorgesehen sein, daß mittels der mechanischen Fangeinrichtung 7 ein Signal ausgelöst wird, das ein erneutes Anfahren des Antriebsmotors nach Auslösen der mechanischen Fangeinrichtung 7 unmöglich macht.In the monitoring device according to the invention and described above, the series connection of the electrical safety device 15 in front of the mechanical safety device 7 is essential, so that there is a forced sequence of the two safety devices 7 and 15, which triggers the electrical safety device 15 and then the mechanical safety device 17. The mechanical catching device 7 is also designed such that after it has been triggered, the door leaf 1 cannot be restarted or moved from the catching position by the drive motor (not shown). Rather, the mechanical catching device 7 must be brought back into its waiting position, ie out of engagement with the running rail 3, in a very targeted manner after the elimination of all errors that have occurred. This transfer is usually done by hand, so that it is ensured that it is impossible to start the drive motor before eliminating all sources of error. It can also be provided that a signal is triggered by the mechanical safety device 7, which makes it impossible to restart the drive motor after the mechanical safety device 7 has been triggered.

In den Darstellungen des zweiten Ausführungsbeispieles nach den Figuren 4 bis 7 sind funktionsgleich arbeitende Teile wie beim Beispiel nach den Figuren 1 bis 3 mit apostrophierten, ansonsten übereinstimmenden Bezugsziffern versehen. Insoweit wird auch hinsichtlich der übereinstimmenden Funktionen und Bewegungen der Teile auf die Beschreibung der Figuren 1 bis 3 bezuggenommen. Auch hier ist im schematisch dargestellten unteren Eckbereich des Torblattes 1, das in seinen unteren Seitenkantenbereichen jeweils eine Laufrolle 2' aufweist, die in jeweils einer Laufschiene 3' geführt ist, ein plattenförmiger Träger 6' vorgesehen, an dem ein Achsstummel 4' der Laufrolle 2' gehalten ist. Der Träger weist seitlich abragende Stege 8' auf, die im wesentlichen im rechten Winkel von der Platte abragend parallel zueinander verlaufen und der Aufnahme der Laufrollenachse 4' und der Achse der insgesamt mit 7' bezeichneten mechanischen Fangeinrichtung dienen.In the illustrations of the second exemplary embodiment according to FIGS. 4 to 7, parts having the same function as in the example according to FIGS. 1 to 3 are provided with apostrophized, otherwise identical reference numerals. In this respect, reference is also made to the description of FIGS. 1 to 3 with regard to the matching functions and movements of the parts. Here, too, in the schematically illustrated lower corner region of the door leaf 1, which in its lower side edge regions each has a roller 2 ', which is guided in a respective rail 3', a plate-shaped carrier 6 ' provided on which an axle stub 4 'of the roller 2' is held. The carrier has laterally projecting webs 8 ', which project substantially parallel to one another at a right angle from the plate and serve to accommodate the roller axis 4' and the axis of the mechanical catch device, designated overall by 7 '.

In Abweichung vom ersten Ausführungsbeispiel ist das Auslöseglied der Fangeinrichtung hier als Schieber 9' ausgebildet, der einen säulenförmigen Mittelteil 9'' und dessen Abmessungen seitlich überragende Stegplatten 9''' aufweist und an dem Träger 6' geradlinig in Bewegungsrichtung des Torblattes verschiebbar gelagert ist. Das Seil 12' durchgreift eine an dem Träger 6' abgestützte Hülse 28, die anderen Endes an der oberen Stegplatte 9''' angreift und die von einer Schraubendruckfeder 18' umgriffen ist. Das an den Hülsendurchgriff anschließende Seilende ist in einem Befestigungselement 11' festgelegt, das mit einem Außengewindeabschnitt aus dem unteren Ende des Mittelteils 9'' jenseits der unteren Stegplatte 9''' aus dem Schieber 9' austritt und mittels konterbarer Muttern 29 bei gestrafftem Seil in der in Figur 6 dargestellten Lage einjustiert ist. Die untere Stegplatte 9''' des Schiebers 9' hält über einen Anschlag 21' das Fangglied 19' in der in Figur 6 gezeigten Position.In a departure from the first exemplary embodiment, the triggering element of the catching device is designed here as a slide 9 ', which has a columnar central part 9' 'and the dimensions of which are laterally projecting web plates 9' '' and is mounted on the carrier 6 'so that it can be moved in a straight line in the direction of movement of the door leaf. The cable 12 'passes through a sleeve 28 which is supported on the carrier 6' and which engages at the other end on the upper web plate 9 '' 'and which is encompassed by a helical compression spring 18'. The end of the cable adjoining the sleeve penetration is fixed in a fastening element 11 'which, with an external thread section from the lower end of the middle part 9' 'beyond the lower web plate 9' '', emerges from the slider 9 'and by means of lockable nuts 29 when the cable is taut in the position shown in Figure 6 is adjusted. The lower web plate 9 ″ ″ of the slide 9 ′ holds the catch member 19 ′ in the position shown in FIG. 6 via a stop 21 ′.

Das Fangglied 19' umfaßt einen Anschlagteil 19'' der über eine Achse 25 mit rechteckigen Querschnitt mit einem Fangexzenter 19''' zu einer verdrehfesten Einheit verbunden ist, wie dies insbesondere die Figuren 5 und 6 erkennen lassen. Der Fangexzenter ist in einem Umfangsbereich, der bei Fangsstellung auf die Laufschiene 3' zu verschwenkt ist, mit spitzzahnartigen Vorsprüngen versehen, hier drei 23 23' 23'', die in der Reihenfolge ihrer Verschwenkstellung auf die Laufschiene 3 zu zunehmend radial weiter abragend ausgebildet und aus der nicht dargestellten Eingriffstellung gesehen in Richtung der Schließstellung des Torblattes geneigt ausgebildet sind, so daß sich ein Wiederhakeneffekt für die Bewegung in die Schließstellung ergibt. Der Angriff dieser Vorsprünge 23... an der Laufschiene 3' erfolgt unter dem Gewicht des zu fangenden Torblattes durch Eindrücken der Sptizzahnform insoweit formschlüssig. Auch hier erfolgt der Eingriff der Vorsprünge des Fangexzenters 19''' an der laufschiene 3' im Nachbarbereich der Rolle 2' an der Unterkante des Torblattes.The catch member 19 'comprises a stop part 19''which is connected via an axis 25 with a rectangular cross section to a catch eccentric 19''' to form a torsion-proof unit, as can be seen in particular in FIGS. 5 and 6. The catch eccentric is provided with pointed teeth-like projections in a circumferential area which is pivoted towards the running rail 3 'in the catching position, here three 23 23' 23 '' which, in the order of their pivoting position on the running rail 3, are designed to protrude increasingly radially and seen from the engagement position, not shown, are inclined in the direction of the closed position of the door leaf, so that there is a barbing effect for the movement into the closed position. The attacks of these projections 23 ... on the running rail 3 'takes place under the weight of the door leaf to be caught by pressing in the spitz tooth shape in a positive manner. Here too, the projections of the catch eccentric 19 '''engage on the running rail 3' in Neighboring area of roller 2 'on the lower edge of the door leaf.

Dem Fangglied 19' ist ein Blockierglied 24 zugeordnet, das einen Blockierexzenter 24' aufweist, der mittels einer Achse 26 drehbar gelagert ist. Der Blockierexzenter 24' entspricht in spiegelbildlicher Anordnung dem Fangexzenter 19''', wie dies insbesondere Figur 5 erkennen läßt. Die beiden Exzenter sind getrieblich über Verzahnungen 30 und 31 verbunden, die bei jedem der Exzenter in dessen Drehrichtung gesehen über einen Teilumfangsbereich vor den Vorsprüngen 23... bzw. 27... ausgebildet sind. Durch die ineinandergreifenden Verzahnungen 30, 31 wird die bei Auslösung des Fanggliedes unter vorgespannter Feder vom Fangexzenter ausgeführte Drehbewegung - in Figur 5 im Gegenuhrzeigersinn - auf den Blockierexzenter 24' - in Figur 5 im Uhrzeigersinn - übertragen, so daß beide Vorsprünge 23... und 27... in Eingriff mit der Laufschiene 3' gelangen. Aufgrund der Neigung der Laufschiene 3' gegenüber der Vertikalen ist die Achse 26 des Blockiergliedes 24 gegenüber der Achse 25 um eine in Figur 5 x bezeichnete Strecke versetzt angeordnet.A blocking member 24 is assigned to the catching member 19 'and has a blocking eccentric 24' which is rotatably mounted by means of an axis 26. The blocking eccentric 24 'corresponds to the catch eccentric 19' '' in a mirror-image arrangement, as can be seen in particular in FIG. The two eccentrics are connected by gearing 30 and 31, which are formed in each of the eccentrics in the direction of rotation over a partial circumferential area in front of the projections 23 ... and 27 .... Due to the interlocking toothings 30, 31, the rotational movement carried out by the catch eccentric when the catch member is released under a pretensioned spring - counterclockwise in FIG. 5 - to the blocking eccentric 24 '- clockwise in FIG. 5 - so that both projections 23 ... and 27 ... engage the running rail 3 '. Due to the inclination of the running rail 3 'with respect to the vertical, the axis 26 of the blocking member 24 is offset from the axis 25 by a distance designated in FIG. 5 x.

Bei Erschlaffen des Seiles über die Betätigung der elektrischen Fangeinrichtung 15' hinaus wird die mechanische Fangeinrichtung 7' dadurch ausgelöst, daß sich der Schieber 9' unter der Kraft der vorgespannten Feder 18' nach unten versetzt - Figur 6 - so daß der Anschlag zwischen der unteren Stegplatte 9''' und Anschlagteil 19'' außer Eingriff gerät, wodurch das Fangglied 19' unter der Kraft der nicht dargestellten vorgespannten Feder, insbesondere Schenkelfeder, in den Eingriff mit der Laufschiene verschwenkt wird. Diese Verschwenkbewegung wird über die Verzahnungen der Exzenter auf das Blockierglied 24 übertragen, so daß auch dieses in Eingriff mit der Laufschiene gelangt.When the rope slackens beyond the actuation of the electrical safety device 15 ', the mechanical safety device 7' is triggered by the fact that the slide 9 'moves downwards under the force of the prestressed spring 18' - FIG. 6 - so that the stop between the lower one Web plate 9 ″ ″ and stop part 19 ″ comes out of engagement, as a result of which the catch element 19 ′ is pivoted into engagement with the running rail under the force of the prestressed spring, in particular leg spring, which is not shown. This pivoting movement is transmitted via the toothing of the eccentric to the blocking member 24, so that this also comes into engagement with the running rail.

Wie die Figuren 4 bis 7 zeigen, sind ansonsten im Verhältnis zum ersten Ausführungsbeispiel bauliche Modifikationen für das zweite Ausführungsbeispiel vorgenommen worden, so die an die andere Fangeinrichtung 7' angepaßte Ausbildung des Trägers 6', die Ausbildung der unterkantenseitigen Umlenkeinrichtung 14' für das Seil 12' und die Ausbildung der oberen Umlenkung für das Seil in Form einer Gleitkufe 13'. Die elektrische Fangeinrichtung 15' stimmt vorzugsweise mit derjenigen 15 des ersten Ausführungsbeispieles überein.As FIGS. 4 to 7 show, structural modifications for the second exemplary embodiment have been made in relation to the first exemplary embodiment, such as the design of the carrier 6 ′ adapted to the other catching device 7 ′, the design of the deflection device 14 ′ on the lower edge for the cable 12 'and the formation of the upper deflection for the rope in the form of a skid 13'. The electrical catching device 15 'is preferably correct with that of the first embodiment.
