Abstract

The invention relates to a drive for closures of apertures, more particularly sectional gates. The sectional gate is made up of slats 1a-1c directly hinged to one another and guided in vertical and horizontal rails 3, 5 on both longitudinal edges. In the deflecting zone between the vertical portion and the horizontal portion of the aperture closure, associated with each edge of the aperture closure is a sprocket wheel 6 engaging with a roller chain. The rollers 21-24 of the roller chain are disposed on pivot pins 17-20 borne by locking members 10-12. The locking members 10-12 are inserted in the ends of every second hollow slat 1a, 1b, 1c. The pivot pins 17-20 are so arranged as to be in alignment with the hinge points 13-15 of the slats 1a-1e hinged to one another.

Description

Die Erfindung bezieht sich auf einen durch einen Antrieb angetriebenen Öffnungsabschluß, wie Tür oder Tor, aus gelenkig miteinander verbundenen hohlen Lamellen, die an den beiden seitlichen Rändern des Öffnungsabschlusses in Schienen geführt sind und beim Öffnen und Schließen von einer ersten Ebene in eine zweite Ebene umgelenkt werden.The invention relates to an opening closure driven by a drive, such as a door or gate, made of hollow slats which are connected to one another in an articulated manner and which are guided in rails at the two lateral edges of the opening closure and are deflected when opening and closing from a first level to a second level will.

Ein solcher Öffnungsabschluß ist aus der FR-PS 2.116.869 bekannt. Eine Besonderheit bei solchen, auch "Sektionaltore" genannten Abschlüssen besteht darin, daß sie im Unterschied in ihrer Länge ausziehbaren Rolläden eine konstante Länge haben. Bei dem bekannten Öffnungsabschluß sind in den Gelenkpunkten der Lamellen, insbesondere als Gelenkzapfen einer Gelenkkette ausgebildete Mitnehmer befestigt, mit denen im Umlenkbereich des Öffnungsabschlusses vorgesehene, insbesondere als Kettenräder ausgebildete Antriebsräder in Eingriff stehen. Diese Art des Antriebes des Öffnungsabschlusses hat gegenüber einem anderen Antrieb, bei dem ein Zugmittel an der oberen Lamelle angeschlagen ist, den Vorteil, daß nicht die zwischen der Umlenkstelle und dem Anschlag des Zugmittels angeordneten Lamellen von dem Gewicht des vor der Umlenkstelle liegenden, herunterhängenden Teil des Öffnungsabschlusses belastet sind. Eine solche Belastung ist insbesondere dann kritisch, wenn die benachbarten, miteinander in Eingriff stehenden Längsränder der Lamellen die Gelenke bilden und keine zusätzliche Entlastung für diese Gelenke vorgesehen ist. Bei dem bekannten Öffnungsabschluß mit im Umlenkbereich des Öffnungsabschlusses vorgesehenem Antrieb sind an beiden Längsrändern des Öffnungsabschlusses Ketten angeordnet, deren Gelenkzapfen in den Gelenkpunkten der Lamelle vorgesehen sind. Die Gelenkzapfen werden von Stopfen getragen, die in den Enden von zylindrischen Hohlkörpern stecken, die zwischen den als entsprechende Lagerschalen ausgebildeten Längsrändern benachbarter Lamellen angeordnet sind. Diese Gelenkketten sorgen für den Zusammenhalt der nicht unmittelbar miteinander verbundenen hohlen Lamellen und zylindrischen Hohlkörper. Von Nachteil ist allerdings, daß der Herstellungs- und Montageaufwand für einen solchen Öffnungsabschluß groß ist.Such an opening closure is known from FR-PS 2.116.869. A special feature of such closures, also called "sectional doors", is that, in contrast to the length of their retractable shutters, they have a constant length. In the known opening closure, drivers designed in the articulation points of the lamellae, in particular as pivot pins of an articulated chain, are fastened, with which drivers provided in the deflection region of the opening termination, drive wheels designed in particular as chain wheels are engaged. This type of drive of the opening closure has the advantage over another drive in which a traction means is attached to the upper slat that the slats arranged between the deflection point and the stop of the traction means do not depend on the weight of the part hanging down in front of the deflection point of the opening closure are charged. Such a load is particularly critical when the adjacent, mutually engaging longitudinal edges of the lamellae form the joints and no additional relief is provided for these joints. In the known opening closure with a drive provided in the deflection area of the opening closure, chains are arranged on both longitudinal edges of the opening closure, the pivot pins of which are provided in the articulation points of the lamella. The hinge pins are carried by plugs which are inserted in the ends of cylindrical hollow bodies which are arranged between the longitudinal edges of adjacent lamellae which are designed as corresponding bearing shells. These link chains ensure the cohesion of the hollow slats and cylindrical hollow bodies which are not directly connected to one another. The disadvantage, however, is that the manufacturing and assembly costs for such an opening closure are large.

Der Erfindung liegt die Aufgabe zugrunde, einen im Aufbau einfacheren Öffnungsabschluß zu schaffen.The object of the invention is to create an opening closure which is simpler in construction.

Diese Aufgabe wird nach einer ersten Alternativen durch folgende Merkmale gelöst:

  • a) Der Öffnungsabschluß besteht aus über ihre gesamte Länge ineinandergreifenden, gelenkig miteinander verbundenen hohlen Lamellen.
  • b) Die beiden seitlichen Ränder des Öffnungsabschlusses sind in Schienen geführt, derart, daß der Öffnungsabschluß beim Öffnen und Schließen von einer ersten Ebene in eine zweite Ebene umgelenkt wird.
  • c) In den Enden jeder zweiten hohlen Lamelle sind Arretierstücke eingesetzt, die durch Übergreifen der Enden der jeweils benachbarten Lamellen die Lamellen gegen gegenseitige Längsverschiebung sichern.
  • d) Die Arretierstücke tragen in den Gelenkpunkten der Lamellen Mitnehmer.
  • e) Mit den Mitnehmern stehen im Umlenkbereich des Öffnungsabschlusses Antriebsräder in Eingriff.
According to a first alternative, this task is solved by the following features:
  • a) The opening closure consists of interlocking, articulated hollow slats over their entire length.
  • b) The two lateral edges of the opening closure are guided in rails such that the opening closure is deflected from a first level into a second level when opening and closing.
  • c) In the ends of every second hollow lamella locking pieces are inserted, which secure the lamellae against mutual longitudinal displacement by reaching over the ends of the adjacent lamellae.
  • d) The locking pieces carry drivers in the hinge points of the slats.
  • e) Drive wheels engage with the drivers in the deflection area of the opening closure.

Nach einer zweiten Alternativen besteht die Lösung in folgenden Merkmalen:

  • a) Der Öffnungsabschluß besteht aus über ihre gesamte Länge ineinandergreifenden, gelenkig miteinander verbundenen hohlen Lamellen.
  • b) Die beiden seitlichen Ränder des Öffnungsabschlusses sind in Schienen geführt, derart, daß der Öffnungsabschluß beim Öffnen und Schließen von einer ersten Ebene in eine zweite Ebene umgelenkt wird.
  • c) Die Gelenke benachbarter Lamellen bestehen aus einer am Längsrand der einen Lamelle vorgesehenen offenen kreiszylindrischen Lagerschale und einem darin gelagerten, am benachbarten Längsrand der anderen Lamelle vorgesehenen kreiszylindrischen Auge, in dessen beiden hohlen Enden Stopfen eingesetzt sind, die mit einem die Lagerschale übergreifenden Kragen die benachbarten Lamellen gegen gegenseitige Längsverschiebung sichern.
  • d) Die Stopfen tragen in den Gelenkpunkten der Lamellen Mitnehmer.
  • e) Mit den Mitnehmern stehen im Umlenkbereich des Öffnungsabschlusses Antriebsräder in Eingriff.
According to a second alternative, the solution consists of the following features:
  • a) The opening closure consists of interlocking, articulated hollow slats over their entire length.
  • b) The two lateral edges of the opening closure are guided in rails such that the opening closure is deflected from a first level into a second level when opening and closing.
  • c) The joints of adjacent lamellae consist of an open circular cylindrical bearing shell provided on the longitudinal edge of one lamella and a circular cylindrical eye mounted therein, provided on the adjacent longitudinal edge of the other lamella, in the two hollow ends of which plugs are inserted, which are connected to the Collar overlapping the bearing shell secure the adjacent slats against mutual longitudinal displacement.
  • d) The plugs carry drivers in the articulation points of the slats.
  • e) Drive wheels engage with the drivers in the deflection area of the opening closure.

Nach einer vorteilhaften Ausgestaltung der Erfindung sind die Mitnehmer als Gelenkzapfen einer Gelenkkette ausgebildet und die Antriebsräder Kettenräder.According to an advantageous embodiment of the invention, the drivers are designed as pivot pins of a link chain and the drive wheels are chain wheels.

Der erfindungsgemäße Öffnungsabschluß ist im Vergleich zu dem bekannten, im Umlenkbereich Antriebsräder aufweisenden Öffnungsabschluß einfacher, weil für den Zusammenhalt der Teile des Öffnungsabschlusses eine Gelenkkette zwar vorteilhaft, aber nicht notwendig ist. Die hohlen Lamellen halten sich vielmehr aufgrund ihrer unmittelbaren gelenkigen Verbindung selbst. Der Antrieb läßt sich bei herkömmlichen Lamellen verwirklichen. Ein Sonderprofil ist nicht erforderlich. Der einzige zusätzliche Aufwand für den Antrieb besteht darin, daß die Arretierstücke beziehungsweise die Stopfen Mitnehmer für die Antriebsräder tragen. Dieser Aufwand ist im Vergleich zu dem Aufwand des bekannten Öffnungsabschlusses mit hohlen Lamellen und zwischen ihnen angeordneten zylindrischen Hohlkörpern und Gelenkketten vernachlässigbar gering.The opening closure according to the invention is simpler in comparison to the known opening closure having drive wheels in the deflection area, because a link chain is advantageous but not necessary for holding the parts of the opening closure together. Rather, the hollow slats hold themselves due to their direct articulated connection. The drive can be realized with conventional slats. A special profile is not required. The only additional effort for the drive is that the locking pieces or the plugs carry drivers for the drive wheels. This effort is negligible compared to the effort of the known opening closure with hollow lamellae and cylindrical hollow bodies and link chains arranged between them.

Sofern an den seitlichen Rändern des Öffnungsabschlusses Gelenkketten vorgesehen sind, ist es von Vorteil, wenn die Gelenkketten auf ihren Gelenkzapfen zwei mit seitlichem Abstand voneinander angeordnete Reihen von Verbindungslaschen aufweisen, zwischen denen die Kettenräder eingreifen. Darüber hinaus ist es von Vorteil, wenn die Gelenkzapfen mit Führungsrollen bestückt sind. Diese können einen größeren Durchmesser als die Laschen haben und in den Schienen geführt sein.If articulated chains are provided on the lateral edges of the opening closure, it is advantageous if the articulated chains have on their articulated pins two rows of connecting straps arranged at a lateral distance from one another, between which the chain wheels engage. It is also an advantage if the pivot pins are equipped with guide rollers. These can have a larger diameter than the tabs and can be guided in the rails.

Beim Einschieben des Öffnungsabschlusses durch die Antriebsräder in die Schienen der zweiten, im wesentlichen horizontalen Ebene ist der Öffnungsabschluß üblicherweise an seiner Unterseite nicht lückenlos abgestützt. Damit der Öffnungsabschluß an dieser Übergangsstelle zwischen dem unterstützenden Antriebsrad und der horizontalen Schiene trotzdem nicht durchhängen kann, ist nach einer Ausgestaltung der Erfindung vorgesehen, daß die an beiden Längsrändern des Öffnungsabschlusses angeordnete Gelenkkette an ihren Gelenkpunkten mit einseitig zu den Antriebsrädern hin wirkenden Abknicksicherungen versehen ist. Da auf der den Antriebsrädern abgewandten Seite die Genlenkkette durch die verlängerte Schiene abgestützt ist und deshalb zu dieser Seite nicht ausknicken kann, ist sie auf der Seite der Antriebsräder, also nach unten durch die Abknicksicherungen gehalten, so daß durch die Antriebsräder der Öffnungsabschluß in gestreckter Lage problemlos in die Führungsschienen eingeschoben werden kann.When the opening closure is pushed into the rails of the second, essentially horizontal plane by the drive wheels, the opening closure is usually not completely supported on its underside. So that the opening at this transition point between the supporting drive wheel and the horizontal rail still cannot sag, according to one embodiment of the invention it is provided that the articulated chain arranged on both longitudinal edges of the opening end is provided at its articulation points with anti-kink devices acting on one side towards the drive wheels. Since the articulated chain is supported on the side facing away from the drive wheels by the extended rail and therefore cannot buckle to this side, it is held on the side of the drive wheels, that is to say downwards by the anti-kink devices, so that the opening closure is stretched by the drive wheels can be easily inserted into the guide rails.

Vorzugsweise sind die Abknicksicherungen an den Verbindungslaschen ausgebildet. Dies kann beispielsweise in der Weise verwirklicht sein, daß jede auf der dem Antriebsrad abgewandten Seite jenseits des Gelenkpunktes der Gelenkkette angeordnete Abknicksicherung aus einem Anschlag, der von einer Verbindungslasche getragen ist, und einem mit diesem Anschlag zusammenwirkenden Widerlager besteht, das von der benachbarten Verbindungslasche getragen ist.The kink protection devices are preferably formed on the connecting straps. This can be realized, for example, in such a way that each kink protection arranged on the side facing away from the drive wheel beyond the articulation point of the articulated chain consists of a stop which is carried by a connecting link and an abutment which cooperates with this stop and which is carried by the adjacent connecting link is.

Der in Figur 1 dargestellte Öffnungsabschluß in Form eines Sektionaltores besteht aus einer Vielzahl von unmittelbar durch angeformte Teile gelenkig miteinander verbundenen Lamellen 1, die an ihren beiden seitlichen Rändern in U-förmig profilierten Schienen 2,3,4,5 in einer vertikalen Ebene und einer horizontalen Ebene geführt sind. Im Umlenkbereich zwischen der vertikalen Ebene und der horizontalen Ebene befindet sich ein Antrieb mit zwei Antriebsrädern 6,7, die beispielsweise von einem Rohrmotor 8 gemeinsam angetrieben werden. Im Umlenkbereich werden die Lamellen 1 in noch zu beschreibender Weise von diesen Antriebsrädern 6,7 formschlüssig angetrieben und geführt.The opening closure shown in Figure 1 in the form of a sectional door consists of a plurality of directly connected to each other by molded parts slats 1, the two sides of which in U-shaped rails 2,3,4,5 in a vertical plane and one horizontal level. In the deflection area between the vertical plane and the horizontal plane there is a drive with two drive wheels 6, 7, which are jointly driven, for example, by a tubular motor 8. In the deflection area, the slats 1 are driven and guided in a form-fitting manner by these drive wheels 6, 7, to be described below.

Wie aus Figur 2 ersichtlich, steckt in jeder zweiten hohl ausgebildeten Lamelle 1a,1b,1c ein Arretierstück 10,11,12, das sich von herkömmlichen Arretierstücken dadurch unterscheidet, daß es in den Gelenkpunkten 13,14,15 zwischen den hintereinander liegenden Lamellen 1a bis 1e Zapfen 17,18,19,20 trägt, die die Gelenkzapfen einer Gelenkkette, insbesondere einer Rollenkette mit Rollen 21,22,23,24 und Laschen 25,26,27,28,29,30,31,32,33,34 bilden. Die Teilung dieser Rollenkette entspricht somit der Teilung der miteinander gelenkig verbundenen Laschen 1. In die Rollenkette greift das Kettenrad 6 ein. Zur Erleichterung des Eingriffs des scheibenförmigen Kettenrades 6 in die Rollenkette sind die Rollen 21 bis 24 keilförmig ausgebildet.As can be seen from FIG. 2, a locking piece 10, 11, 12 is inserted in every second hollow lamella 1a, 1b, 1c, which differs from conventional locking pieces in that it lies in the articulation points 13, 14, 15 between the lamellae 1a lying one behind the other to 1e pin 17,18,19,20, which carries the pivot pins of a link chain, in particular a roller chain with rollers 21,22,23,24 and plates 25,26,27,28,29,30,31,32,33, 34 form. The division of this roller chain thus corresponds to the division of the link plates 1 which are connected to one another in an articulated manner. The chain wheel 6 engages in the roller chain. To facilitate the engagement of the disk-shaped chain wheel 6 in the roller chain, the rollers 21 to 24 are wedge-shaped.

Bei dem Öffnungsabschluß gemäß Fig. 4 und 5 sind die Lamellen in ihren Gelenkpunkten ebenfalls durch angeformte Teile unmittelbar gelenkig miteinander verbunden. An den Längsrändern benachbarter Lamellen ist eine offene zylindrische Lagerschale 36 und ein darin gelagertes hohlzylindrisches Auge 35 angeformt. In den offenen Enden eines jeden Auges 35 sitzen Stopfen 37, die einen Kragen 38 und einen als Mitnehmer einer Gelenkkette ausgebildeten Gelenkzapfen 39 tragen. Die Krägen 38 sichern die benachbarten Lamellen gegen gegenseitige Längsverschiebung. Die Funktion der Krägen können allerdings auch auf den Gelenkzapfen 39 angeordnete Rollen oder die Verbindungslaschen der Gelenkketten übernehmen.4 and 5, the lamellae are also directly articulated to one another at their articulated points. At the longitudinal edges of adjacent lamellae is an open cylindrical bearing shell 36 and one which is mounted therein molded hollow cylindrical eye 35. In the open ends of each eye 35 there are plugs 37 which carry a collar 38 and a hinge pin 39 designed as a driver of an articulated chain. The collars 38 secure the adjacent slats against mutual longitudinal displacement. The function of the collars can, however, also be taken over by rollers arranged on the pivot pin 39 or the connecting plates of the link chains.

Bei dem gegenüber Fig. 2 und 3 abgewandelten Ausführungsbeispiel der Figuren 6 und 7 ist eine einseitig wirkende Abknicksicherung vorgesehen. Diese Abknicksicherung besteht aus einem Anschlag 30′, der an dem dem Antriebsrad 6 abgewandten Rand der äußeren Verbindungslasche 30 als die innere Verbindungslasche 32 übergreifender Steg ausgebildet ist, und aus einem Widerlager 32′, das von der dem Antriebsrad 6 abgewandten Kante der inneren Lasche 32 gebildet ist. Der Anschlag 30′ erstreckt sich über den vom Gelenkzapfen 20 gebildeten Gelenkpunkt hinaus. Mit dieser Abknicksicherung wird erreicht, daß in dem Bereich, in dem die Gelenkkette weder durch das Antriebsrad 6 noch durch die Schiene 5 unterstützt wird die Gelenkkette und damit auch der Öffnungsabschluß nicht in Richtung des Antriebsrades 6 abknicken kann. Da ein Abknicken der Gelenkkette und des Öffnungsabschlusses zu der dem Antriebsrad 6 abgewandten Seite durch die bis in den Bereich des Antriebsrades 6 einseitig verlängerte Schiene 5 verhindert wird, ist die Gelenkkette und damit auch der Öffnungsabschluß in gestreckter Lage geführt und kann durch das Antriebsrad 6 in die Schiene 5 eingeschoben werden, ohne zu der einen oder der anderen Seite abknicken zu können.In the exemplary embodiment of FIGS. 6 and 7 modified compared to FIGS. 2 and 3, a one-way kink protection is provided. This protection against kinking consists of a stop 30 ', which is formed on the edge of the outer connecting plate 30 facing away from the drive wheel 6 as a web overlapping the inner connecting plate 32, and from an abutment 32', which is remote from the drive wheel 6 edge of the inner plate 32 is formed. The stop 30 'extends beyond the hinge point formed by the hinge pin 20. With this kink protection it is achieved that in the area in which the articulated chain is neither supported by the drive wheel 6 nor by the rail 5, the articulated chain and thus also the opening closure cannot bend in the direction of the drive wheel 6. Since kinking of the articulated chain and the opening end to the side facing away from the drive wheel 6 is prevented by the rail 5 which is extended on one side up to the region of the drive wheel 6, the articulated chain and thus also the opening end is guided in an extended position and can be guided by the drive wheel 6 in the rail 5 are inserted without being able to bend to one or the other side.

Bei dem Ausführungsbeispiel der Fig. 8 und 9 werden bei der Abknicksicherung der Anschlag 30˝ von einer nach außen abgebogenen Nase der inneren Verbindungslasche 30a und das Widerlager 32˝ von einer Kante einer Stufe am oberen Rand der äußeren Verbindungslasche 32a gebildet.In the embodiment of FIGS. 8 and 9, the stop 30˝ from one to the outside when securing against kinking bent nose of the inner connecting plate 30a and the abutment 32˝ formed by an edge of a step at the upper edge of the outer connecting plate 32a.
