Description

Die Erfindung bezieht sich auf ein Fanggerät mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a fishing gear with the features of the preamble of claim 1.

Solche Fanggeräte, die vielfach mit Fangklinken arbeiten, sind in verschiedensten Ausführungen bekannt, so beispielsweise aus der DE-AS 27 35 123.Such fishing gear, which often work with catch pawls, are known in a wide variety of designs, for example from DE-AS 27 35 123.

Von diesen Fanggeräten wird eine schnelle und zuverläßige Reaktion erwartet, wenn der jeweils zugeordnete Zugmittelstrang schlaff wird, beispielsweise weil die Gewichtsausgleichseinrichtung oder die Antriebseinrichtung ausfällt bzw. der Zugmittelstrang selbst reißt. Die bekannten Fanggeräte arbeiten jedoch vielfach zu langsam, sind zu aufwendig gebaut oder nicht sicher gegen Beschädigungen und müssen häufig gewartet werden, was zum Teil sehr schwierig ist.A quick and reliable response is expected from these fishing devices if the respectively assigned traction cable strand becomes slack, for example because the weight compensation device or the drive device fails or the traction cable strand itself breaks. However, the known fishing gear often works too slowly, is too expensive to build or is not safe from damage and has to be serviced frequently, which is sometimes very difficult.

Der Erfindung liegt die Aufgabe zugrunde, ein Fanggerät der eingangs genannten Art zu schaffen, das schnell und sicher arbeitet, gegen Verschmutzung und Beschädigung geschützt ist und sich insbesondere auch leicht warten und auf Funktionsfähigkeit überprüfen läßt.The invention has for its object to provide a gear of the type mentioned, which works quickly and safely, is protected against dirt and damage and in particular can also be easily maintained and checked for functionality.

Ausgehend von einem Fanggerät mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst.Starting from a gear with the features of the preamble of claim 1, this object is achieved according to the invention by its characterizing features.

Durch die Anordnung praktisch sämtlichter im Zuge eines Fangvorganges zu bewegende Teile im Inneren eines Gehäuses wird die Fangeinrichtung zunächst gegen Schmutz und Beschädigung bewahrt, die Anordnung ist dabei so getroffen, daß bei Erschlaffen des zugeordneten Zugmittelstranges oder dessen Reißen das Fangglied in die Fangstellung gerät, bevor sich das Verschlußblatt oder Torblatt aufgrund seiner Massenträgheit nennenswert abwärts bewegt. Die in diesem Zusammenhang eingesetzte Feder befindet sich ebenfalls innerhalb des Gehäuses, sie ist damit vor allem auch dagegen geschützt, daß ihre wirksame Federlänge durch ungewollt in den Federweg eingelagerte Fremdkörper eingeschränkt wird.By arranging practically all the parts to be moved in the course of a catching process inside a housing, the catching device is initially protected against dirt and damage, the arrangement being such that the catching member gets into the catching position before the associated traction cable strand slackens or tears due to its inertia, the shutter leaf or door leaf moves downwards to a significant extent. The spring used in this context is also located within the housing, so it is primarily protected against the fact that its effective spring length is restricted by foreign bodies that are unwantedly stored in the spring travel.

Das Fangglied kann grundsätzlich entlang einer translatorischen Strecke durch den federbelasteten Bolzen im Falle der Seilerschlaffung von der Freigabestellung in die Fangstellung überführt werden. In besonders bevorzugter Weise ist das Fangglied als verschwenkbar innerhalb des Gehäuses gelagerte Fangklinke ausgebildet, die mit einer in Bolzenlängsrichtung gesehenen Schrägfläche an dem innerhalb des Gehäuses liegenden Bolzenendes eingreift, so daß der Bolzen aufgrund seiner Federbelastung die Klinke nach außerhalb des Gehäuses in die Fangstellung verschwenkt, sobald die Feder aufgrund eines Seilbruches oder dgl. arbeiten kann.In principle, the catching element can be transferred from the release position to the catching position along a translational path by the spring-loaded bolt in the case of slackening of the rope. In a particularly preferred manner, the catch member is designed as a catch pawl which is pivotably mounted within the housing and engages with an inclined surface seen in the longitudinal direction of the bolt on the bolt end lying inside the housing, so that the bolt pivots the catch toward the outside of the housing into the catch position due to its spring load, as soon as the spring can work due to a broken rope or the like.

Die zwischen dem Verschlußblatt und dem Zugmittelstrang angeordnete Feder hat noch den Vorteil, daß insbesondere bei Handbetätigung aufgebrachte Beschleunigungen des Verschlußblattes gedämpft auf die Gewichtsausgleichseinrichtung übertragen werden, so daß die Zugmittelstränge, die insbesondere als Seile ausgebildet sind, nicht von den Seiltrommeln springen können. Hierzu hat man bislang einen gesonderten Federarm vorgesehen. Dadurch daß die erfindungsgemäß ausgebildete Fangeinrichtung diese Wirkungsfunktion miterfüllt, kann man auf den sonst an gleichem Platz vorzusehenden Federhebel verzichten.The spring arranged between the closure sheet and the traction element strand has the advantage that accelerations of the closure leaf applied in manual operation, in particular, are transmitted in a dampened manner to the weight compensation device, so that the traction element strands, which are designed in particular as ropes, cannot jump off the cable drums. So far, a separate spring arm has been provided for this. Characterized in that the catching device designed according to the invention also fulfills this function, one can do without the spring lever which is otherwise to be provided in the same place.

Das Fanggerät ist besonders bevorzugt derart ausgebildet, daß die Bewegungsrichtung des Fanggliedes etwa senkrecht zur Verschlußblattebene verläuft, so daß das Fangglied in der Fangstellung an einer Fangschiene angreift, die vorteilhaft nahe an der Brandung der zur verschließenden Toröffnung angeordnet werden kann. Dadurch lassen sich die beim Fangen auftretenden, unter Umständen erheblichen Kräfte gut in das Mauerwerk ableiten, die übrige Konstruktion kann entsprechend leichter ausgeführt werden. Zu diesem Zwecke ist das Fanggliedgehäuse, das sich im Fangfall gegenüber dem Verschlußblatt verschiebt, zumindest an seiner der Fangschiene abgewandten Seite führend abgestützt. Die Fangeinrichtung arbeitet grundsätzlich über den gesamten Weg hinweg, die das Verschlußblatt zwischen seiner öffnungsstellung und seiner Schiefstellung zurücklegt. Bei Oberkopftoren, insbesondere Deckengliedertoren, verschwinden jedoch die Kräfte, die der Antrieb und/oder die Gewichtsausgleichseinrichtung auf das Torblatt ausübt, wenn sich dieses in der öffnungsstellung befindet, d, h, die untere Kante im Bereich der bogenförmigen übergänge der Führungsschienen gelegen ist. Dieses praktische Verschwinden der Seilspannung kann dazu ausgenutzt werden, die Fangklinke aus der Freigabestellung in die Fangstellung zu überführen, ohne das sie in einen Fangeingriff mit der Fangschiene gerät, da in diesem Bereich ein Fangen nicht erforderlich ist. Dies hat den besonderen Vorteil, daß die Fangklinke gängig gehalten wird. Ähnliches erreicht man bei einem handbetätigten Tor, wenn das Torblatt gegen einen Anschlag in die öffnungsstellung läuft.The fishing gear is particularly preferably designed such that the direction of movement of the catch member runs approximately perpendicular to the plane of the closure leaf, so that the catch member engages in the catch position on a catch rail which can advantageously be arranged close to the surf of the gate opening to be closed. This allows the forces that occur when catching, which may be considerable, to be dissipated well into the masonry; the rest of the construction can be carried out correspondingly more easily. For this purpose, the catch member housing, which moves in relation to the locking sheet in the event of a catch, is supported at least on its side facing away from the catch rail. The catching device basically works over the entire path that the closing sheet travels between its open position and its inclined position. In overhead gates, especially overhead sectional gates, the forces that drive and / or weight disappear same device exerts on the door leaf when it is in the open position, that is, the lower edge is located in the region of the arcuate transitions of the guide rails. This practical disappearance of the rope tension can be used to transfer the catch from the release position to the catch position without it engaging in catch with the catch rail, since catch is not necessary in this area. This has the particular advantage that the catch is kept common. A similar situation can be achieved with a manually operated door if the door leaf runs into the open position against a stop.

Normalerweise reißt nur ein Seil bzw. bricht nur eine Gewichtsausgleichsfeder, so daß bei getrennter Welle das Tor einseitig gefangen wird und sich verkanten kann. Außerdem führt das Torblatt in einem gewissen Spielraum seitliche Bewegungen aus. Durch entsprechend breit bemessene Fangöffnungen kann man dafür sorgen, daß in all diesen Fällen kein Verklemmen eintritt. Man hat nämlich vielfach das Bedürfnis, ein gefangenes Torblatt zu öffnen oder auch zu schließen. Dies geschieht einfach dadurch, daß man mit einem Gabelstapler oder dgl. das Torblatt untergreift und anhebt. Für das Absenken läßt sich in besonders bevorzugter Ausführung der Erfindung das Fangglied in der Freigabestellung arretieren, beispielsweise durch eine Schraube in dieser Stellung festlegen. Auf diese Weise ist ein öffnen und Schließen des Torblattes möglich. Im Normalfall kann das Fangglied durch eben diese Arretierungsöffnung mit Hilfe eines Stiftes oder dgl. zur überprüfung der Funktionsfähigkeit besonders einfach betätigt werden.Usually only one rope breaks or only one weight compensation spring breaks, so that the door is caught on one side and can tilt when the shaft is separated. In addition, the door leaf makes lateral movements within a certain scope. With appropriately wide catch openings you can ensure that no jamming occurs in all these cases. You often have the need to open or close a trapped door leaf. This is done simply by reaching under and lifting the door leaf with a forklift or the like. For lowering, in a particularly preferred embodiment of the invention, the catch member can be locked in the release position, for example fixed in this position by a screw. In this way, the door leaf can be opened and closed. In the normal case, the catch member can be actuated particularly simply through this locking opening with the aid of a pin or the like to check the functionality.

Das Fanggerät läßt sich sehr einfach an Gebäudeverschlüssen der in Frage stehenden Art anbringen. So lößt man bei bestehenden, seilgetragenen Torblättern lediglich die Seilbefestigung an den seitlich abragenden Befestigungsbolzen und hängt an diese den Bolzen des Fanggliedgehäuses an, während man das Seilende in das Fanggliedgehäuse verlegt und dort befestigt, was vorzugsweise an der Schwenkachse der Fangklinke geschieht. Im Falle eines motorisch betriebenen Torblattes läßt sich die Versetzung des Fanggliedes in die Fangstellung zur Betätigung eines Speisestromschalters ausnutzen. In einer bevorzugten Ausführung der Erfindung wird hierzu eine zweite Bewegung unter der Kraft einer zweiten Feder vorgesehen, die auf die das Fangglied auslösende Feder folgend arbeitet.The gear can be easily attached to building locks of the type in question. With existing, cable-borne door leaves, all you have to do is loosen the cable attachment to the laterally protruding fastening bolts and attach them to the bolts of the safety gear housing, while the cable end is laid in the safety gear housing and fastened there, which is preferably done on the pivot axis of the safety catch. In the case of a motorized door leaf, the catch member can be moved into the catch position for actuation of a supply current switch. In a preferred embodiment of the invention, a second movement under the force of a second spring is provided for this purpose, which works following the spring that triggers the catching element.

Weitere Ausführungen der Erfindung ergeben sich aus den Unteransprüchen im Zusammenhang mit dem in der Zeichnung wiedergegebenen Ausführungsbeispielen, auf das besonders Bezug genommen wird und dessen nachfolgende Beschreibung die Erfindung näher erläutert.Further embodiments of the invention result from the subclaims in connection with the exemplary embodiments shown in the drawing, to which particular reference is made and the following description of which explains the invention in more detail.

Show it
  • 1 shows a lower side area of a door leaf with roller guide rail and safety gear in a top view of the door leaf area;
  • Figure 2 seen the same corner area, but in the direction of the wire rope.
  • 3 shows a view of the narrow side of the door leaf with a cut catch housing and the catch pawl in the release position;
  • Fig. 4 is a representation corresponding to FIG. 3 with the catch pawl in the catch position.

Wie insbesondere aus den Figuren 1 und 2 ersichtlich, sind an dem Torblatt über Rollenhalter 2 Rollen 3 befestigt, die in eine Führungsschiene 4 eingelagert sind. Von diesen Rollenhaltern und Rollen sind insbesondere bei einem sogenannten Sektionaltor eine ganze Reihe vorhanden, wie dies bekannt ist. Weiterhin hat man sich selbstverständlich die für den im Bild rechten Randbereich vorgesehenen Bauteile und Baumaßnahmen spiegelsymmetrisch für den nicht dargestellten linken Randbereich des Torblattes vorzustellen. Die Führungsschienen 4 sind mittels Halterungen 5 im Bereich der seitlichen Gebäudeöffnungsberandung in nicht weiter dargestellter Weise festgelegt. An den Halterungen 5 sind zugleich Fangschienen 7 befestigt, die sich somit ebenfalls im Bereich der seitlichen Gebäudeöffnungsberandung 6 befinden und dort entsprechend gut abstützten können. Wie insbesondere Figur 1 erkennen läßt, sind die Fongschienen 7 mit einer Reihe in Längsrichtung aufeinanderfolgend angeordneter Fangöffnungen 8 versehen, die verhältnismäßig breit ausgeführt sind, im vorliegenden Falle breiter als die ihnen zugewandte Seite eines Fanggliedgehäuses 10, das im Schmalseitenbereich des Torblattes angeordnet ist, wie dies v. a. Fig. 2 erkennen läßt. An der der Fangschiene 7 gegenüberliegenden Gehäuseseite greift ein Führungsbeschlag 11 an, so daß das - wie später noch geschildert - im Fangfall sich gegenüber dem Torblatt 1 entlang seiner Schmalseite verschiebende Fanggliedgehäuse 10 mit in der Fangstellung befindlichen Fangglied - Fig. 4 - nicht von der Fangschiene 7 fortgerichtet ausweichen kann.As can be seen in particular from FIGS. 1 and 2, rollers 3, which are embedded in a guide rail 4, are fastened to the door leaf via roller holders. A large number of these roller holders and rollers are available, in particular in a so-called sectional door, as is known. Furthermore, of course, one has to imagine the components and construction measures provided for the right edge area in the image in mirror symmetry for the left edge area (not shown) of the door leaf. The guide rails 4 are fixed by means of brackets 5 in the area of the side edge of the building opening in a manner not shown. To the stops stanchions 5 are at the same time fixed rails 7, which are thus also located in the area of the side building opening 6 and can support them there accordingly. As can be seen in particular in Figure 1, the fong rails 7 are provided with a series of longitudinally arranged catch openings 8 which are relatively wide, in the present case wider than the side of a catch member housing 10 facing them, which is arranged in the narrow side area of the door leaf, such as this reveals above all Fig. 2. A guide fitting 11 engages on the housing side opposite the catch rail 7, so that the catch member housing 10 with catch member located in the catch position - FIG. 4 - does not move from the catch rail - as described later - when the catch member 10 moves along its narrow side with respect to the door leaf 1 7 can avoid evasive.

Fig. 1 zeigt - wie auch die Figuren 3 und 4 - einen Bolzen 12, der bei 13 an einem Befestigungsbolzen 27 angreift, wobei 13 eine öse innerhalb einer Lasche sein kann. Dieser Bolzen 12 greift durch die untere Stirnseite 17 des Gehäuses 10 in dessen Inneres ein. Durch die dieser Stirnseite gegenüberliegende obere Stirnseite 16 ist eine Klemmhülse 15 hindurchgeführt, mit welcher das als Zugmittelstrang dienende Drathseil 14 zu einer Schlaufe geformt zusammengefaßt ist.Fig. 1 shows - like the figures 3 and 4 - a bolt 12 which engages at 13 on a fastening bolt 27, 13 may be an eye within a tab. This bolt 12 engages through the lower end face 17 of the housing 10 in its interior. A clamping sleeve 15 is passed through the upper end face 16 opposite this end face, with which the wire rope 14 serving as a traction means strand is combined to form a loop.

Die Teilschnittdarstellungen nach den Fig. 3 und 4 zeigen die Ausbildung des Fanggliedgehäuses 10 und der diesem zugeordneten Bauteile deutlich. Das Gehäuse weist innerhalb seiner der Fangschiene 7 zugewandten Längsseitenwand 18 eine seitliche öffnung 19 auf, die der Gehäuseseite 20 gegenüberliegt, an welcher der Führungsbeschlag 11 abstützend angreift. Die weiteren seitlichen Gehäusewandungen 21, die sich senkrecht zu den Landungen 18 und 20 erstrecken und von denen man aufgrund des Gehäuseschnittes nur die hintere erkennt, halten zwischen sich eineSchwenkachse 22, um welche die Fangklinke 23 verschwenkbar gelagert ist. Wie Fig. 3 erkannen läßt, befindet sich die Schwenkklinke samt der Klinkennase innerhalb des Fanggliedgehäuses 10, wenn die Fangklinke 23 aufgrund eines ausreichendes Spannungszustandes in dem zuge- hörigen Seil 14 sich in der Freigabestellung befindet, die den normalen Betriebsfall bei intaktem Seil, ordnungsgemäß arbeitender Gewichtsausgleichseinrichtung und dgl. darstellt. Der mittels der Use 13 und dem Befestigungsbolzen 27 im unteren Seitenbereich des Torblattes gehaltene Bolzen 12 durchgreift die untere Stirnseite 17 durch eine Durchführungsöffnung 28 verschiebbar. In seinem im Inneren des Gehäuses liegenden Endbereich ist der Bolzen 12 mit einem Kopf 29 versehen, der derart verbreitert ausgeführt ist, daß die Seitenflächen des Bolzenkopfes an den Gehäuseinnenseitenwandungen geführt wird. Zwischen der Innenwand der unteren Stirnseite 17 des Gehäuses 10 und der dieser gegenüberliegenden Unterfläche des Kopfes 29 ist eine Schraubendruckfeder 32 vorgesehen, durch welche der Bolzenschaft hindurchgeführt ist. Um die Schraubenfeder herum ist einnhülsenförmiger Anschlag 33 angeordnet, der wiederum einen Endes an der Innenfläche der Sitrnseite 17 und anderen Endes an der dieser zugewandten Unterfläche des Kopfes 29 abgestützt ist. Wie in Fig. 3 gezeigt, befindet sich der Bolzen 12 bei gespanntem Seil 14 mit seinem Kopf 29 in Anlage mit dem Anschlag 33, so daß die Schraubendruckfeder 32 ihre größtmögliche Zusammendrückung aufweist.The partial sectional views according to FIGS. 3 and 4 clearly show the design of the catching member housing 10 and the components assigned to it. Within its longitudinal side wall 18 facing the catch rail 7, the housing has a lateral opening 19 which lies opposite the housing side 20, on which the guide fitting 11 engages in a supporting manner. The further lateral housing walls 21, which extend perpendicular to the landings 18 and 20 and of which only the rear one can be seen due to the housing cut, hold between them a pivot axis 22 about which the catch pawl 23 is pivotably mounted. As can be seen in FIG. 3, the swivel pawl together with the pawl nose is located within the catch member housing 10 when the catch pawl 23 is in the associated is h örigen cable 14 in the release position, which represents the normal operation with intact rope properly working weight balancer and the like.. The bolt 12 held in the lower side region of the door leaf by means of the use 13 and the fastening bolt 27 passes through the lower end face 17 through a through opening 28. In its end region located inside the housing, the bolt 12 is provided with a head 29 which is widened in such a way that the side surfaces of the bolt head are guided on the inner walls of the housing. Between the inner wall of the lower end face 17 of the housing 10 and the lower surface of the head 29 opposite this, a helical compression spring 32 is provided, through which the bolt shaft is passed. Arranged around the helical spring is an n- shaped stop 33, which in turn is supported at one end on the inner surface of the side 17 and at the other end on the lower surface of the head 29 facing it. As shown in Fig. 3, the bolt 12 is in tension with the rope 14 with its head 29 in contact with the stop 33, so that the helical compression spring 32 has its greatest possible compression.

An dem Bolzenkopf 29 ist eine Abschrägung 30 ausgebildet, die hinsichtlich der Schräge mit dem Verlauf einer Schrägfläche 31 übereinstimmt, an der die Abschrägung 30 anliegt und die ausgehend von der Klinkennase 24 in dem der Schwenkachse 22 gegenüberliegenden Bereich der Fangklinke an dieser ausgebildet ist. Diese Anlage zeigt Fig. 3 für die Freigabestellung 25 der Fangklinke.On the bolt head 29, a bevel 30 is formed which, with respect to the bevel, corresponds to the course of an inclined surface 31 against which the bevel 30 rests and which, starting from the pawl nose 24, is formed on the catch pawl in the region of the catch pawl opposite the pivot axis 22. This system is shown in FIG. 3 for the release position 25 of the catch.

Wenn das Seil 14 reißt oder aus anderen Gründen seine Spannung verliert, so verschiebt sich das Gehäuse 10 gegenüber dem Bolzen 12 nach unten, und zwar unter der Kraft der zusammengedrückten und sich nunmehr entspannenden Feder 32 weitaus schneller als die Anfangsgeschwindigkeit des nunmehr absturzgefährdeten Torblattes. In Fig. 4 ist die Relativlage zwischen dem in durchgezogenen Strichen wiedergegebenen Gehäuse 10 und dem strichpunktiert wiedergegebenen Kopf 29 des Bolzens 12 dargestellt, der also bei sich entspannender Feder 32 in diese strichpunktierte Endverschiebelage 40 in das Gehäuseinnere hinein gelangt. Dabei drückt der Kopf 29 über seine Abschrägung 30 an der Schrägfläche 31 der Fangklinke 23 entlanggleitend die Fangklinke in Drehbewegung um die Schwenkachse 22 herum mit der Klinkennase 24 zuerst durch die seitliche öffnung 19, so daß die Klinkennase 24 in die nach unten nächstfolgende Fangöffnung 8 der Fangschiene 7 eingreift, wie dies Fig. 4 zeigt. In dieser Lage befindet sich die Fangklinke 23 somit-in der Fangstellung 26.If the cable 14 breaks or loses its tension for other reasons, the housing 10 moves downwards relative to the bolt 12, namely under the force of the compressed and now relaxing spring 32, much faster than the initial speed of the door leaf, which is now at risk of falling. In Fig. 4 the relative position between the solid line 10 housing 10 and the dash-dotted head 29 of the bolt 12 is shown, so that the spring 32 relaxing in this dotted end shift position 40 gets into the interior of the housing. The head 29 presses its bevel 30 along the inclined surface 31 of the catch pawl 23, sliding the catch pawl in rotary motion around the pivot axis 22 with the pawl nose 24 first through the lateral opening 19, so that the pawl nose 24 into the catch opening 8 next to the bottom Catch rail 7 engages, as shown in Fig. 4. The catch pawl 23 is thus in the catch position 26 in this position.

Die Klemmhülse 15 des Seiles 14 durchgreift eine Durchtrittsöffnung 34 in der oberen Stirnseite 16 des Gehäuses 10, und zwar ebenfalls längsverschiebbar. Die im Inneren des Gehäuses 10 liegende Seilschlaufe greift in eine Kausche 35 ein, die ihrerseits die Schwenkachse 22 umfaßt, und zwar mit einem gewissen Spiel derart, daß bei Schlaffwerden des Seiles eine zwischen der Innenwand der Stirnseite 16 und der Kausche 35 angeordnete Druckfeder, die das Seil 14 und dessen durch die Hülse 15 zurückgeführtes Ende umgreift, die Kausche 35 gegenüber der Schwenkachse 22 in das Gehäuseinnere um eine geringe Strecke verschiebt. An der Kausche 35 greift ein Betätigungsglied 38 eines elektrischen Schalters 39 an, mit welchem ein hier vorgesehener Antriebsmotor abgeschaltet wird. Da die Schraubendruckfeder 32, die den Bolzen 12 umfaßt, härter bzw. steifer ausgebildet ist als die Druckfeder 36, die das Seil 14 umgreift, verschiebt sich zunächst das Gehäuse 10 gegenüber dem Bolzen 12, so daß die Fangklinke 23 in ihre Fangstellung 26 gerät, woraufhin die Verschiebung der Kausche 35 zur Betätigung des Schalters 39 Platz greift.The clamping sleeve 15 of the cable 14 passes through a passage opening 34 in the upper end face 16 of the housing 10, and also in a longitudinally displaceable manner. The rope loop lying inside the housing 10 engages in a thimble 35, which in turn comprises the pivot axis 22, with a certain amount of play in such a way that when the rope slackens a compression spring arranged between the inner wall of the end face 16 and the thimble 35, the engages around the rope 14 and its end returned through the sleeve 15, displaces the thimble 35 by a small distance with respect to the pivot axis 22 into the housing interior. On the thimble 35, an actuator 38 of an electrical switch 39 engages with which a drive motor provided here is switched off. Since the helical compression spring 32, which comprises the bolt 12, is designed to be harder or stiffer than the compression spring 36, which encompasses the cable 14, the housing 10 first moves relative to the bolt 12, so that the catch pawl 23 moves into its catch position 26, whereupon the displacement of the thimble 35 for actuating the switch 39 takes place.

Wie Fig. 3 zeigt, weist die Fangklinke 23 an ihrer der Fangschiene 7 abgewandten Seite eine Gewinde-Sacklochbohrung 41 auf, die in der Freigabestellung 25 der Klinke 23 hinsichtlich ihrer Eingangsöffnung mit einer Bohrung 42 in der Gehäuseseite 20 fluchtet. Durch eine von der Gehäuseaußenseite her durch die Bohrung 42 in das Gewindesackloch 41 eingeführte Schraube kann die Fangklinke 23 in der Freigabestellung gehalten bzw. in diese zurückgeführt und dort arretiert werden, wenn das Torblatt nach einem Fangfall nicht nur geöffnet werden soll - die Fangklinke würde wie eine Ratsche wirken -, sondern auch verschließbar sein soll, beispielsweise mit Hilfe eines Gabelstaplers, bis das defekte Seil bzw. der zum Schlaffwerden des Seiles führende Fehler beseitigt worden ist.As shown in FIG. 3, the catch pawl 23 has on its side facing away from the catch rail 7 a threaded blind hole 41 which, in the release position 25 of the pawl 23, is aligned with a bore 42 in the housing side 20 with respect to its input opening. By means of a screw inserted from the outside of the housing through the bore 42 into the threaded blind hole 41, the catch pawl 23 can be held in the release position or returned to it and locked there if the door leaf is not only to be opened after a fall - the catch pawl would be like a ratchet - but also lockable should be, for example with the help of a forklift, until the defective rope or the fault leading to the rope becoming slack has been eliminated.

Wie bereits eingangs kurz erwähnt, sind die Fangöffnungen 8 quer zur Bewegungsrichtung des Torblattes 1 sehr breit ausgebildet, und zwar um ein Vielfaches der Breite der Klinkennase 24, so daß das Tor in jeder möglichen seitlichen Versetzbewegung sicher gefangen werden kann. Ein einseitiger Fehler, beispielsweise Seilriß, führt zu keinem Verklemmen des Tores derart, daß dieses nicht angehoben werden kann.As already briefly mentioned at the beginning, the catch openings 8 are very wide transversely to the direction of movement of the door leaf 1, namely by a multiple of the width of the latch nose 24, so that the door can be caught safely in any possible lateral displacement movement. A one-sided error, such as a rope break, does not result in the door jamming in such a way that it cannot be lifted.
