Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff der Patentansprüche 1, 7 oder 8.The invention relates to a device according to the preamble of claims 1, 7 or 8.

Eine Vorrichtung der eingangs genannten Art ist aus der DE-C-225 170 bekannt. Mit dieser Vorrichtung läßt sich eine Arretierung des Rolladenpanzers im herabgelassenen Zustand erreichen; im hochgezogenen Zustand wird ein Höherziehen des Rolladenpanzers dadurch vermieden, daß die Anschlagelemente in eine Aussparung in der Führungsschiene eingreifen, so daß der letzte Fallstab des Rolladenpanzers nicht über eine oberste Stellung hinaus in Richtung auf den Rolladenkasten vedagerbar ist. Dabei wirken die in die Aussparungen seitlicher Führungsschienen eingreifenden Anschlagelemente als Anschlagelemente für die Beendigung der Bewegung des Rolladenpanzers.A device of the type mentioned is known from DE-C-225 170. With this device, the roller shutter curtain can be locked in the lowered state; in the raised state, raising the roller shutter curtain is avoided by the stop elements engaging in a cutout in the guide rail, so that the last drop bar of the roller shutter curtain cannot be predicted beyond an uppermost position in the direction of the roller shutter box. The stop elements engaging in the recesses in the lateral guide rails act as stop elements for ending the movement of the roller shutter curtain.

Die DE-U-70 15 861 gibt eine Vorrichtung zur Begrenzung derAufwickelbewegung eines Rolladenpanzers als bekannt an, bei welcher ein in dem letzten Fallstab ausgebildetes Lager ein Profilscharnier aufnimmt. Das Profilschamier ist von der Seite her in den letzten Fallstab eingeschoben und wird in dem in dem Fallstab ausgebildeten Lager derart gelagert, daß es aus einer Lage, in der es um 90° gegenüber der Wandung des Fallstabes geschwenkt ist, in eine Lage parallel zur Wandung geschwenkt werden kann. In der Sperrstellung steht das Profilscharnier über die Vorderwand des Fallstabes nach vorne ab. Das Profilschamier ist bei dieser Vorrichtung außerhalb der seitlichen Führungsschiene angeordnet und findet seinen Gegenanschlag an der Unterkante des Rolladenkastens.DE-U-70 15 861 discloses a device for limiting the winding movement of a roller shutter curtain as known, in which a bearing formed in the last drop bar accommodates a profile hinge. The profiled hinge is inserted from the side into the last drop bar and is stored in the bearing formed in the drop bar in such a way that it is in a position parallel to the wall from a position in which it is pivoted by 90 ° relative to the wall of the drop rod can be pivoted. In the locked position, the profile hinge protrudes forward over the front wall of the drop bar. In this device, the profiled hinge is arranged outside the side guide rail and finds its counter-stop on the lower edge of the roller shutter box.

Die DE-A-27 28 440 beschreibt eine Ausstoßvorrichtung für Rolladenpanzer, die eine Begrenzung der Aufwickelbewegung des Rolladenpanzers und das sichere Herablassen des Rolladenpanzers aus der hochgezogenen Position bewirkt. Diese Vorrichtung weist eine in den letzten Fallstab einzusetzende Lagereinrichtung auf mit einer quer zur Achse des Fallstabes ausgebildeten Aufnahmehülse für einen Federstab, an dessen unterem Ende ein Anschlagteil befestigt ist, während es oberhalb des Lagerlementes eine den Federstab umgebende Feder aufweist. Ein am oberen Ende des Federstabes ausgebildetes Widerlager dient als Begrenzung der den Federstab umgebenden Feder. Das Lagerelement ist zur Aufnahme des Anschlagteiles mit einer seitlichen unteren Aussparung versehen, in welcher das Anschlagteil in der Sperrstellung zu liegen kommt. Das auf das untere Ende des Federstabes aufgesetzte Anschlagteil hat im wesentlichen T-förmige Gestalt und ist zusammen mit dem Federstab gegenüber dem Lagerelement drehfähig, wenn es gegenüber dem Lagerelement nach unten über die Aussparung hinweg gezogen wird. Das Anschlagteil ist damit in einer Richtung senkrecht zur Achse des letzten Fallstabes nach unten, d.h. in Laufrichtung des Rolladenpanzers nach unten gegenüber dem letzten Fallstab verlagerbar und in einer Ebene drehfähig, die etwa parallel liegt zum letzten Fallstab.DE-A-27 28 440 describes an ejection device for roller shutter curtain which limits the winding movement of the roller shutter curtain and the safe lowering of the roller shutter curtain from the raised position.

An abutment formed at the upper end of the spring bar serves to limit the spring surrounding the spring bar. The bearing element is provided for receiving the stop part with a lateral lower recess in which the stop part comes to rest in the locked position. The stop part placed on the lower end of the spring bar has a substantially T-shaped shape and, together with the spring bar, is rotatable relative to the bearing element when it is pulled downward over the recess relative to the bearing element. The stop part is thus in a direction perpendicular to the axis of the last drop bar downwards, i.e. Can be moved downwards in the direction of travel of the roller shutter curtain relative to the last drop bar and rotatable in a plane that is approximately parallel to the last drop bar.

Fig. 1 zeigt eine Teilschnittansicht des letzten Fallstabes eines Rolladenpanzers entsprechend der Schnittlinie I-I in Fig. 2. Der letzte Fallstab bzw. Rolladenstab ist in Fig. 1 mit dem Bezugszeichen 1 bezeichnet und weist gemäß der Seitenansicht nach Fig. 2 mehrere Stege, vorzugsweise Stege 2, 3, auf und besteht aus Kunststoff oder Metall. In dem zwischen den Stegen 2, 3 definierten Hohlraum ist ein Lagerelement 4 eingesetzt, beispielsweise aus Metall oder Kunststoff, das an seiner mit 4a bezeichneten unteren Stirnfläche eine halbkreisförmige und dem Krümmungsradius eines Bolzens 5 entsprechende Konfiguration hat, nämlich derart, daß die dadurch gebildete Fläche an der Stirnkante 4a zur drehfähigen Lagerung des Bolzens 5 dient. Der Bolzen 5 ist Bestandteil eines mit 6 bezeichneten Anschlagelementes, das den aus Fig. 2 ersichtlichen Anschlag 7 aufweist. Der Bolzen 5 und/oder der Anschlag 7 bestehen aus Metall oder Kunststoff. Die Materialwahl bestimmt sich nach den jeweiligen Erfordernissen an die Stabilität des Anschlagelementes, wobei das gesamte Anschlagelement 6 vorzugsweise aus Metall hergestellt ist, während das Lagerelement 4 nicht unbedingt aus Metall besteht, sondern auch aus Kunststoff hergestellt sein kann.Fig. 1 shows a partial sectional view of the last drop bar of a roller shutter curtain corresponding to section line II in Fig. 2. The last drop bar or roller shutter bar is designated by the reference numeral 1 in Fig. 1 and has several webs, preferably webs, according to the side view of Fig. 2 2, 3, and is made of plastic or metal. In the cavity defined between the webs 2, 3, a bearing element 4 is used, for example made of metal or plastic, which has a semicircular configuration on its lower end face denoted by 4a and corresponding to the radius of curvature of a bolt 5, namely in such a way that the surface formed thereby on the front edge 4a for the rotatable mounting of the bolt 5 is used. The bolt 5 is part of a stop element designated 6, which has the stop 7 shown in FIG. 2. The bolt 5 and / or the stop 7 are made of metal or plastic. The choice of material is determined according to the respective requirements for the stability of the stop element, the entire stop element 6 preferably being made of metal, while the bearing element 4 is not necessarily made of metal, but can also be made of plastic.

Rolladenpanzer werden im allgemeinen auf den beiden Seiten in Führungsschienen 8 geführt, wie dies in Fig. 1 bezüglich der linken Seite des Fallstabes 1 angedeutet ist. Die U-förmige Führungsschiene 8 ist in Fig. 1 in Teilschnittdarstellung angedeutet. Damit ist aus Fig. 1 erkennbar, daß sowohl der Anschlag 7 als auch ein Teil des Fallstabes sowie der übrigen Rolladenstäbe innerhalb der zugehörigen Führungsschienen liegt und an einer der oberen Endposition des Rolladenpanzers entsprechenden Stelle der Führungsschiene 8 ein Gegenelement als Begrenzung für den Anschlag 7 vorgesehen ist.Roller shutter curtains are generally guided on both sides in guide rails 8, as is indicated in FIG. 1 with regard to the left side of the drop bar 1. The U-shaped guide rail 8 is indicated in Fig. 1 in a partial sectional view. 1 that both the stop 7 and part of the drop rod and the other roller shutter rods lie within the associated guide rails and a counter element is provided as a limit for the stop 7 at a position on the guide rail 8 corresponding to the upper end position of the roller shutter curtain is.

Der Anschlag 7 in der in Fig. 2 gezeigten Stellung hat eine Länge 1, die größer als die Stärke des Fallstabes 1 ist Die mit 9 bezeichneten, mit oberen Ende der Führungsschienen 8 ausgebildeten Begrenzungselemente sind derart im Bewegungsweg des Anschlagelementes 7 vorgesehen, daß die mit 7a und 7b bezeichneten oberen Kanten der Anschläge 7 in der oberen Endstellung des Rolladenpanzers an den Begrenzungselementen 9 zur Anlage kommen, wenn der Rolladenpanzer entlang der Führungsschienen 8 nach oben gezogen wird. Die Ausführungsform nach Fig. 1 und 2 wird dann angewandt, wenn die Begrenzungselemente, in Fig. 1 durch das Bezugszeichen 9 angedeutet, im Bereich der Schenkel der U-förmigen Führungsschiene ausgebildetsind und damitdie Kanten 7a, 7b des Anschlages 7 beaufschlagen, wenn der Rolladenpanzer nach oben gezogen ist. Gleiches gilt, wenn gemäß dem DE-GM 7541435 ein Einlauftrichter vorgesehen ist, welcher im oberen Endbereich der Führungsschiene 8 eine Reduzierung des freien Querschnittes bewirkt, wobei dann die Anschlagkanten 7a, 7b an dem Einlauftrichter anliegen. Fig. 3a veranschaulicht den Fallstab 1 in seiner oberen Endstellung, wobei der Anschlag 7 an den Begrenzungselementen 9 anliegtThe stop 7 in the position shown in Fig. 2 has a length 1, which is greater than the strength of the drop rod 1. The designated 9, with the upper end of the guide rails 8 formed limiting elements are provided in the path of movement of the stop element 7 that the 7a and 7b refer to the upper edges of the stops 7 in the upper end position of the roller shutter curtain against the limiting elements 9 when the roller shutter curtain is pulled upwards along the guide rails 8. The embodiment according to FIGS. 1 and 2 is used when the delimiting elements, indicated by reference number 9 in FIG. 1, are formed in the region of the legs of the U-shaped guide rail and thus act on the edges 7a, 7b of the stop 7 when the roller shutter curtain is pulled up. The same applies if, according to DE-GM 7541435, an inlet funnel is provided which brings about a reduction in the free cross section in the upper end region of the guide rail 8, the stop edges 7a, 7b then abutting the inlet funnel. 3a illustrates the drop rod 1 in its upper end position, the stop 7 abutting the limiting elements 9

Gemäß der Erfindung ist das Anschlagelement 6 in oder an dem Lagerelement 4 drehfähig gelagert. Der Bolzen 5 ist mit wenigstens zwei senkrecht zueinanderstehenden Bohrungen versehen, von welchen eine in Fig. 1 mit 11 und die andere mit 12 bezeichnet ist. Die Bohrung 11 dient zurAufnahme eines Splintes 13 oder dergleichen. Wenn der Splint 13 in die Bohrung 11 eingesetzt ist, verhindert er eine Drehung des Bolzens 5 gegenüber dem Lagerelement 11 und somit auch gegenüber dem Fallstab 1, so daß das Anschlagelement 6 mit Anschlag 7 in der in Fig. 2 gezeigten Querstellung arretiert ist. Hierdurch wird entsprechend Fig. 3a die Bewegung des Rolladenpanzers bei Erreichen der oberen Endposition durch die Begrenzungselemente 9 in der Führungsschiene 8 sichergestellt. Wird der Splint 13 aus dem Bolzen und damit aus dem Fallstab 1 entfernt, ist eine Drehung des Anschlagelementes 6 um zumindest 90° in die in Fig. 3b gezeigte Drehlage möglich, die der in Fig. 5 in Schnittdarstellung wiedergegebenen Ansicht entspricht. Da der Anschlag 7 etwa gleiche Breite b wie Tiefe des Fallstabes 1 aufweist, kann nach erfolgter Drehung des Anschlagelementes 6 aus der in Fig. 1 und 3a gezeigten Position um 90° der Fallstab 1 an den Begrenzungselementen 9 gemäß Fig. 3b vorbei nach oben bewegt werden, d.h. der gesamte Rolladenpanzer läßt sich vollständig in einen nicht dargestellten Rolladenkasten hineinziehen. Die Drehung des Anschlagelementes 6 wird vorzugsweise mittels des Splintes 13 durchgeführt, indem dersplint 13vollständig aus der Bohrung 11 des Bolzens 5 herausgezogen wird und in die zweite Bohrung 12 von unten mit dem Schenkel 13a zur Drehung des Bolzens 5 über etwa 90° innerhalb des Schlitzes 14 hineingesteckt wird.According to the invention, the stop element 6 is rotatably mounted in or on the bearing element 4. The bolt 5 is provided with at least two bores perpendicular to one another, one of which is denoted by 11 in FIG. 1 and the other by 12. The bore 11 serves to receive a split pin 13 or the like. When the cotter pin 13 is inserted into the bore 11, it prevents the bolt 5 from rotating with respect to the bearing element 11 and thus also with respect to the drop bar 1, so that the stop element 6 is locked with the stop 7 in the transverse position shown in FIG. 2. In this way, according to FIG. 3a, the movement of the roller shutter curtain is ensured by the limiting elements 9 in the guide rail 8 when the upper end position is reached. If the cotter pin 13 is removed from the bolt and thus from the drop rod 1, the stop element 6 can be rotated by at least 90 ° into the rotational position shown in FIG. 3b, which corresponds to the view shown in section in FIG. 5. Since the stop 7 has approximately the same width b as the depth of the drop rod 1, after the stop element 6 has been rotated from the position shown in FIGS. 1 and 3a by 90 °, the drop rod 1 can move upward past the limiting elements 9 according to FIG. 3b become, ie the entire roller shutter curtain can be pulled completely into a roller shutter box, not shown. The rotation of the stop element 6 is preferably carried out by means of the split pin 13, in that the split pin 13 is completely pulled out of the bore 11 of the bolt 5 and into the second bore 12 from below with the leg 13 a for rotating the bolt 5 over approximately 90 ° within the slot 14 is inserted.

Der Schlitz 14 ist über eine Höhe h von unten in den Fallstab eingefräst, so daß der Schlitz von der Unterkante des Fallstabes bis etwa zur Stirnkante 4a des Lagerelementes 4 reicht.The slot 14 is in from a height h from below milled the drop rod so that the slot extends from the lower edge of the drop rod to approximately the front edge 4a of the bearing element 4.

Wenn der Splint 13 bei Einnahme der Drehlage des Bolzens und Anschlagelementes 3 nach Fig. 1 in die Bohrung 11 eingesetzt ist und damit der Splint 13 gegenüber dem Bolzen 5 die in Fig. 4 angedeutete Lage einnimmt, wird eine Verlagerung des Anschlagelementes 6 aus dem Fallstab und dem Lagerteil 4 heraus dadurch verhindert, daß der Splint 13 an den Schlitzwandungen anliegt. Fig. 6 zeigt eine Schnittansicht entlang der Linie 1-I (Fig. 2) entsprechend Fig. 5, wobei das Anschlagelement 6 nicht dargestellt ist und woraus hervorgeht, daß der Schlitz 4 die Außenwand des Fallstabes 1 im unteren Bereich des Fallstabes durchsetztIf the cotter pin 13 is inserted into the bore 11 when the pin and stop element 3 in accordance with FIG. 1 are taken up, and thus the cotter pin 13 assumes the position indicated in FIG. 4 relative to the pin 5, the stop element 6 is displaced from the drop rod and the bearing part 4 prevents thereby that the split pin 13 rests on the slot walls. Fig. 6 shows a sectional view along the line 1-I (Fig. 2) corresponding to Fig. 5, wherein the stop element 6 is not shown and from which it can be seen that the slot 4 penetrates the outer wall of the drop bar 1 in the lower region of the drop bar

Das Lagerelement 4 gemäß den Fig. 1 bis 6 erstreckt sich von der in Fig. 1 linken Kante des Fallstabes 1 nur über einen Teil der gesamten Fallstabbreite in den Fallstab hinein und dient zur Begrenzung eines Hohlraumes 10 gegenüber dem unteren Steg 3 zur Aufnahme des Bolzens 5. Das Lagerelement 4 ist nach einer weiteren Ausführungsform derart ausgebildet, daß es den gesamten Hohlraum 28 im Fallstab 1 zwischen dem Steg 2 und dem Steg 3 ausfüllt, somit keinen zylindrischen Hohlraum 10 zur Aufnahme des Bolzens 5 gegenüber dem Steg 3 definiert, sondern zwischen dem Steg 2 und 3 mit einer zylindrischen Bohrung zur Aufnahme des Bolzens 5 ausgebildet ist, wobei in diesem Fall der Schlitz 14 nicht nurdurch den Fallstab 1 hindurchgefräst ist, sondern auch in Deckung mit dem Schlitz 14 des Fallstabes im Lagerelement 4 über eine bestimmte Höhe vom Steg 3 nach oben ausgebildet ist, um die Drehung des Bolzens 5 mittels eines Splintes 13 oder dergleichen zu ermöglichen. Zweckmäßigerweise ist die Toleranz der Bohrung oder des Hohlraumes zur Aufnahme des Bolzens 5 derart gewählt, daß der Bolzen 5 nur unter Überwindung einer Reibungskraft in die in Fig. 3b dargestellte Lage verdrehbar ist und in dieser Lage durch die vorhandenen Reibungskräfte verbleibt, so daß eine unbeabsichtigte Weiterdrehung oder Rückdrehung des Anschlagelementes 6 aus der in Fig. 3b gezeigten Lage in eine Schräglage oder die in Fig. 3a gezeigte Lage ausgeschlossen ist. Weiterhin kann eine Arretiereinrichtung, z. B. eine zu der im peripheren Bereich des Bolzens 5 vorgesehenen Bohrung bzw. Aussparung 11 parallele mittige Bohrung 11' vorgesehen sein, die nach Drehung um 90° aus der in Fig. 10 dargestellten und Fig.1 entsprechenden Lage heraus in Flucht zu einer weiteren Bohrung 15 im Lagerelement 4 (Fig. 5) verbringbar ist und mittels eines Splintes oder dergleichen eine Arretierung des Anschlagelementes 6 gegenüber dem Lagerelement 4 in der Drehstellung nach Fig. 3b und Fig. 5 ermöglicht. Die Bohrung 11 kann auch als Vertiefung des Bolzens 5 zum Durchschieben des Schenkels 13a des Splintes 13 ausgebildet sein.The bearing element 4 according to FIGS. 1 to 6 extends from the left edge of the drop bar 1 in FIG. 1 only over part of the entire drop bar width into the drop bar and serves to delimit a cavity 10 with respect to the lower web 3 for receiving the bolt 5. The bearing element 4 is designed according to a further embodiment such that it fills the entire cavity 28 in the drop bar 1 between the web 2 and the web 3, thus not defining a cylindrical cavity 10 for receiving the bolt 5 relative to the web 3, but between the web 2 and 3 is formed with a cylindrical bore for receiving the bolt 5, in which case the slot 14 is not only milled through the drop bar 1, but also in register with the slot 14 of the drop bar in the bearing element 4 over a certain height from Web 3 is formed upwards to enable the rotation of the bolt 5 by means of a split pin 13 or the like. The tolerance of the bore or of the cavity for receiving the bolt 5 is expediently chosen such that the bolt 5 can only be rotated while overcoming a frictional force into the position shown in FIG. 3b and remains in this position due to the existing frictional forces, so that an unintentional one Further rotation or backward rotation of the stop element 6 from the position shown in FIG. 3b into an inclined position or the position shown in FIG. 3a is excluded. Furthermore, a locking device, for. For example, a central bore 11 ′ parallel to the bore or recess 11 provided in the peripheral region of the bolt 5 may be provided, which after rotation through 90 ° from the position shown in FIG. 10 and FIG. 1 is in alignment with another Bore 15 in the bearing element 4 (FIG. 5) can be brought in and enables the stop element 6 to be locked relative to the bearing element 4 in the rotational position according to FIGS. 3b and 5 by means of a split pin or the like. The bore 11 can also be formed as a depression of the bolt 5 for pushing the leg 13a of the split pin 13.

Nach einer weiteren Ausführungsform, die in Fig. 8 dargestellt ist, bewirkt eine Schraube, beispielsweise eine Madenschraube 18, die Arretierung des Bolzens 5 und damit des Anschlagelementes 6 in der Fig. 1 und 2 entsprechenden Drehlage des Anschlagelementes 6 dadurch, daß die Schraube 18 durch die äußere Wandung 19 in ein im Bolzen 5 ausgebildetes Gewinde 20 eingeschraubt ist. Nach Ausführung einer Drehung des Bolzens 5 um 90° fluchtet eine zweite Gewindebohrung 21, die eine Querbohrung zur Gewindebohrung 20 darstellt, mit der in der äußeren Wandung 19 ausgebildeten Öffnung 22, so daß nach Einschrauben der Schraube 18 das Anschlagelement in seiner Fig. 3b entsprechenden Lage fixiert ist. Die Arretierung bzw. Fixierung des Bolzens 5 in seinen beiden möglichen Stellungen wird bei der Ausführungsform nach Fig. 8 und 9 dadurch erreicht, daß die Schraube 18 in dem Fallstab 1 derart angeordnet wird, daß sie im Bolzen 5 und der zugehörigen Öffnung 22 der äußeren Wandung 19 sitzt. Bei der Ausführungsform nach Fig. 8 und 9 erübrigt sich damit ein Lagerelement 4 gemäß den Ausführungsformen nach Fig. 1 bis 6, wobei der Bolzen 5 an seinem die Gewindebohrungen 20, 21 beinhaltenden Ende auf dem Steg 3 und zumindest auf einem Stegabschnitt 3' aufliegt, wobei der Stegabschnitt 3' an der linken Kante des Fallstabes 1 durch eine Öffnung oder Aussparung 23 festgelegt ist. Damit liegt das Anschlagelement 6 sicher auf dem Steg bzw. Stegabschnitt 3 bzw. 3' auf, wenn der Rolladenpanzer nach oben gegen das bzw. die Begrenzungselemente 9 bewegt wird.According to a further embodiment, which is shown in FIG. 8, a screw, for example a grub screw 18, locks the bolt 5 and thus the stop element 6 in FIGS. 1 and 2 corresponding rotational position of the stop element 6 in that the screw 18th is screwed through the outer wall 19 into a thread 20 formed in the bolt 5. After rotating the bolt 5 by 90 °, a second threaded bore 21, which is a transverse bore to the threaded bore 20, is aligned with the opening 22 formed in the outer wall 19, so that after screwing in the screw 18 the stop element in FIG. 3b corresponds Location is fixed. The locking or fixing of the bolt 5 in its two possible positions is achieved in the embodiment according to FIGS. 8 and 9 in that the screw 18 is arranged in the drop bar 1 such that it is in the bolt 5 and the associated opening 22 of the outer Wall 19 sits. In the embodiment according to FIGS. 8 and 9, there is therefore no need for a bearing element 4 according to the embodiments according to FIGS. 1 to 6, the bolt 5 resting on the web 3 and at least on a web section 3 ′ at its end containing the threaded bores 20, 21 , wherein the web section 3 'on the left edge of the drop bar 1 is fixed by an opening or recess 23. The stop element 6 thus lies securely on the web or web section 3 or 3 ′ when the roller shutter curtain is moved upwards against the delimitation element or elements 9.

Wird die Breite b des Anschlages 7 etwas kleiner als die Stärke des Fallstabes bzw. die innere lichte Weite des durch die Wandungen des Fallstabes gebildeten Hohlraumes 28 gewählt, wobei die Öffnung 23 in ihren Ausmaßen ebenfalls der lichten Weite des Fallstabes entspricht, kann das gesamte Anschlagelement 6 im Bedarsfall nach Lösung der Schraube 18 und geringfügiger Bewegung in die Führungsschiene 8 hinein mit dem einen Ende 5a zuerst durch die Öffnung 23 aus dem Fallstab entfernt werden.If the width b of the stop 7 is selected to be somewhat smaller than the thickness of the drop rod or the inside clear width of the cavity 28 formed by the walls of the drop rod, the dimensions of the opening 23 also corresponding to the clear width of the drop rod, the entire stop element can 6 in case of need after loosening the screw 18 and slight movement into the guide rail 8 with one end 5a first be removed from the drop rod through the opening 23.

Fig. 11 zeigt eine weitere Ausführungsform der Erfindung, bei welcher der Bolzen 5 wesentlich kürzer ausgebildet ist als bei der Ausführungsform nach Fig. 8 oder 10 und der Fallstab eine Öffnung 23 an seiner unteren Stimfläche aufweist, wie dies in Verbindung mit Fig. 8 beschrieben ist. Der Bolzen 5 ist mittels einer Schraube 18 in der Lage nach Fig. 3a fixiert und gegen eine Verschiebung gesichert, vorzugsweise auch durch eine zweite Schraube 25, wobei der Stegabschnitt 3' zur Lagerung des Bolzens 5 aus reicht und die beiden Schrauben 18 und 25 zusätzlich eine Lagerung des Bolzens 5 zwischen der äußeren Wandung 19 und einer inneren Wandung 24 des Fallstabes gewährleisten. Außerdem ist ein Schlitz 14 vorgesehen, wie dies vorstehend in Verbindung mit Fig. 5 erläutert wurde. Nach Entfernung der Schrauben 18, 25, die den Stift somit gegenüber den beiden Wandungen 19, 24 des Fallstabes halten, läßt sich das Anschlagelement 6 mit Hilfe einer zum Gewinde für die Schraube 25 ausgebildeten Querbohrung 27 um 90° drehen und dann über die Öffnung 23 durch den zwischen den Stegen 2 und 3 gebildeten Hohlraum 28 aus dem Fallstab herausnehmen. Bei dieser Ausführungsform ist somit vor einer Herausnahme des Anschlagelementes 6 eine Drehung um 90° erforderlich, damit das Anschlagelement 6 mit dem Anschlag 7 in den Hohlraum 28 hineingezogen werden kann, bevor das Anschlagelement 6 über die Öffnung 23 vollständig aus dem Fallstab 1 entfernt wird.FIG. 11 shows a further embodiment of the invention, in which the bolt 5 is substantially shorter than in the embodiment according to FIG. 8 or 10 and the drop rod has an opening 23 on its lower end face, as described in connection with FIG. 8 is. The bolt 5 is fixed by means of a screw 18 in the position according to FIG. 3a and secured against displacement, preferably also by a second screw 25, the web section 3 'being sufficient for mounting the bolt 5 and the two screws 18 and 25 additionally ensure storage of the bolt 5 between the outer wall 19 and an inner wall 24 of the drop rod. A slot 14 is also provided, as explained above in connection with FIG. 5. After removing the screw ben 18, 25, which thus hold the pin relative to the two walls 19, 24 of the drop rod, the stop element 6 can be turned by 90 ° with the aid of a transverse bore 27 designed for the screw 25 and then through the opening 23 through the between remove the webs 2 and 3 formed cavity 28 from the drop bar. In this embodiment, a rotation through 90 ° is thus required before the stop element 6 is removed so that the stop element 6 with the stop 7 can be drawn into the cavity 28 before the stop element 6 is completely removed from the drop bar 1 via the opening 23.

Bei den vorstehend beschriebenen Ausführungsformen ist vorgesehen, daß das Begrenzungselement oder die Begrenzungselement 9 an den Schenkeln der Führungsschienen 8 vorgesehen sind. Ersichtlicherweise können die Begrenzungselemente 9 oder eine entsprechende Ausbildung eines Einlauftrichters derart konzipiert sein, daß der Begrenzungsabschnitt von der Basis der U-förmigen Führungsschiene 8 absteht, d. h. mittig in den Raum zwischen der Basis der Führungsschiene 8 und der Seitenkante des Fallstäbes 1 ragt, wie dies in Fig. 12 dargestellt ist. In diesem Fall würde eine Drehung des Anschlages 7 nicht bewirken, daß eine Bewegung des Rolladenpanzers über das Begrenzungselement 9' in Fig. 11 hinaus möglicht ist. Fig. 13 zeigt eine entsprechende Möglichkeit des Begrenzungselementes 9' im Basisteil der Führungsschiene 8 entsprechend Fig. 12. Bei einer derartigen Ausbildung der Begrenzungselemente 9' ist der Anschlag 7 aus der Führungsschiene 8 zu entfernen, z. B. dadurch daß gemäß Fig. 7 das Anschlagelement 6 über eine Schraube oder Niet 30 schwenkbar gelagert ist und eine zweite Schraube 31 das Anschlagelement 6 in der gestrichelt dargestellten Lage in Fig. 13 fixiert. Nach Entfernung der Schrauben 31 läßt sich das Anschlagelement 6 in die voll ausgezeichnete Lage, d. h. um etwa 90° in den Hohlraum 28 hinein verlagern. In der gestrichelt dargestellten Lage liegt das Anschlagelement 6 auf dem Stegabschnitt 3' auf, wie dies vorstehend erläutert ist. Bei der Ausführungsform nach Fig. 13 ist es, wie vorstehend bereits beschrieben, notwendig, daß der Anschlag 7 etwa s kleiner als der Hohlraum 28 dimensioniert ist, damit der Anschlag 7 in den Hohlraum 28 verschwenkt werden kann. Eine Drehung um die Achse des Bolzens 5 ist bei der Ausführungsform nach Fig. 13 nicht erfordedich.In the embodiments described above, it is provided that the limiting element or the limiting element 9 are provided on the legs of the guide rails 8. Obviously, the delimiting elements 9 or a corresponding design of an inlet funnel can be designed such that the delimiting section protrudes from the base of the U-shaped guide rail 8, i. H. protrudes centrally into the space between the base of the guide rail 8 and the side edge of the drop bar 1, as shown in FIG. 12. In this case, a rotation of the stop 7 would not have the effect that a movement of the roller shutter curtain beyond the limiting element 9 'in FIG. 11 is possible. FIG. 13 shows a corresponding possibility of the limiting element 9 'in the base part of the guide rail 8 corresponding to FIG. 12. With such a configuration of the limiting elements 9', the stop 7 must be removed from the guide rail 8, e.g. B. in that the stop element 6 is pivotally mounted via a screw or rivet 30 according to FIG. 7 and a second screw 31 fixes the stop element 6 in the position shown in broken lines in FIG. 13. After removing the screws 31, the stop element 6 can be in the fully excellent position, i.e. H. shift by about 90 ° into the cavity 28. In the position shown in dashed lines, the stop element 6 rests on the web section 3 ', as explained above.

Der Bolzen 5 ist mit einer Rille 45 versehen, in die mittels eines Schraubenziehers oder dergleichen eingegriffen werden kann, um das Anschlagelement 6 aus der in Fig. 17 gezeigten Position nach links aus dem Fallstab 1 heraus zu verschieben. Die im Lagerelement 4 ausgebildete Öffnung 46 definiert mit ihren Wänden 46a und 46b die Größe der möglichen seitlichen Verschiebung des Bolzens 5. Wenn die Ausnehmung 45 in FluchtzurWandung 46a des Lagerelementes 4 gelangt, hat das Anschlagelement seine Endstellung erreicht, in welcher der Anschlag aus dem Fallstab 1 herausragt ; in dieser Position ist der Bolzen 5 durch eine Bohrung 47 mit Hilfe eines Splintes oder dergleichen verdrehbar, indem über den Schlitz 14 in die Querbohrung 47 der Splint eingesetzt und der Bolzen 5 verdreht wird, bis der Anschlag 7 die in Fig. 3a gezeigte Querlage erreicht hat.Fig. 17 shows a representation corresponding to Fig. 15; development of the device in which the stop element 6 is rotatable and is also displaceable relative to the bearing element 4. In the position shown in FIG. 17, the stop element 6 can be locked with respect to the slot 14 by means of a pin (not shown in further detail), the stop 7 taking the position shown in FIG. 3b and being arranged within the drop rod, i. H. does not protrude laterally from the drop rod The bolt 5 is provided with a groove 45 which can be engaged by means of a screwdriver or the like in order to move the stop element 6 out of the drop bar 1 from the position shown in FIG. 17. The opening 46 formed in the bearing element 4 defines with its walls 46a and 46b the size of the possible lateral displacement of the bolt 5. When the recess 45 comes into alignment with the wall 46a of the bearing element 4, the stop element has reached its end position in which the stop from the drop bar 1 protrudes; in this position, the bolt 5 can be rotated through a bore 47 with the aid of a split pin or the like, by inserting the split pin into the transverse bore 47 through the slot 14 and rotating the bolt 5 until the stop 7 reaches the transverse position shown in FIG. 3a Has.

Die Fig. 18 und 19 zeigen eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung. In den Fallstab 1 ist als Anschlagelement 6' ein in Seitenansicht im wesentlichen T-förmiges Element eingesetzt, wie Fig. 19 zeigt, wobei der T-Abschnitt untenliegend vorgesehen ist. Das Anschlagelement 6' ist mittels einer oder zweier Schrauben gegenüber den Wandungen fixiert, wie dies aus Fig. 19 hervorgeht, in welcher die Schrauben durch die Linien 50 und 51 angedeutet sind. Der Fallstab 1 ist an seinen unteren Seitenkanten mit Ausschnitten zu versehen, die in Fig. 20 durch das Bezugszeichen 52 angedeutet sind und durch welche das Anschlagelement 6' in den Fallstab und in dessen Hohlraum 28 von unten nach oben hinein verlagerbar ist, bis das Anschlagelement an dem Steg 2 anstößt. Zur Entfernung eines derartigen Anschlagelementes 6' sind lediglich die Schrauben 50, 51 zu lösen, so daß das Anschlagelement 6 nach unten aus dem Fallstab 1 herausgezogen werden kann und damit eine Bewegung des Rolladenpanzers über das Begrenzungselement 9 hinaus ermöglicht Das unter Bezugnahme auf Fig. 18 und 19 beschriebene Anschlagelement 6' weist in Bezug auf seinen T-Abschnitt 53 größere Breite auf als die Stärke des Fallstabes 1 ist, so daß die mit 53a und 53b bezeichneten Flächen in der bereits unter Bezugnahme auf Fig. 3a beschriebenen Weise mit den Begrenzungselementen 9 in Anlage gelangen, wenn der Rolladenpanzer nach oben gezogen wird.18 and 19 show a further embodiment of the device according to the invention. In the drop rod 1, an essentially T-shaped element is used as a stop element 6 'in side view, as shown in FIG. 19, the T section being provided at the bottom. The stop element 6 'is fixed with respect to the walls by means of one or two screws, as can be seen from FIG. 19, in which the screws are indicated by lines 50 and 51.
