Definitions

  • the invention relates to a blind closure for closing an opening, comprising a plurality of interconnected slats, which are guided displaceably on their end faces directed perpendicular to the longitudinal direction of the slat, and a drive device for opening and closing the blind.
  • Closures of this type are known for a wide variety of purposes.
  • the slats of the blind are generally articulated together. To open the opening, the blind is pulled back completely and usually wound up on a roll or at least deflected in the housing to be closed. A selective release of any section of the opening to be closed is not possible with a conventional blind closure of the type mentioned above.

  • the arrangement is such that two adjacent slats can be displaced in opposite directions to one another in the direction of their longitudinal axes until the claw-like edge sections disengage from one another.
  • the threads on the bearing pins become effective again and lead to a rotation of the slats about their longitudinal axis.
  • the invention has for its object to provide a blind closure with which it is possible to selectively release a limited opening section within the opening frame closed by the entire blind, while the remaining parts of the opening remain closed.

  • the connecting element is preferably biased into its engagement position by a return spring, it also being provided with an instruction surface for the automatic engagement of the counter element of the respectively adjacent lamella. In this way, the two blind sections only need to be pushed together again to close the partial opening, so that the connecting element engages in the corresponding counter element of the adjacent slat.
  • the hook-shaped connecting elements are each pivotably mounted on the end faces of the slats about axes parallel to the longitudinal direction of the slats and the counter-element is in each case formed by a pin likewise arranged on the end face of the respectively adjacent slat.

Description

Die Erfindung betrifft einen Jalousieverschluß zum Verschließen einer Öffnung, umfassend eine Mehrzahl von miteinander verbundenen Lamellen, die an ihren senkrecht zur Lamellenlängsrichtung gerichteten Stirnseiten verschiebbar geführt sind, und eine Antriebsvorrichtung zum Öffnen und Schließen der Jalousie.The invention relates to a blind closure for closing an opening, comprising a plurality of interconnected slats, which are guided displaceably on their end faces directed perpendicular to the longitudinal direction of the slat, and a drive device for opening and closing the blind.

Verschlüsse dieser Art sind für die verschiedensten Zwecke bekannt. Dabei sind die Lamellen der Jalousie im allgemeinen gelenkig miteinander verbunden. Zur Freigabe der Öffnung wird die Jalousie vollständig zurückgezogen und dabei meist auf eine Rolle aufgewickelt oder zumindest in dem zu verschließenden Gehäuse umgelenkt. Eine selektive Freigabe eines beliebigen Abschnittes der zu verschließenden Öffnung ist mit einem herkömmlichen Jalousieverschluß der vorstehend genannten Art nicht möglich.Closures of this type are known for a wide variety of purposes. The slats of the blind are generally articulated together. To open the opening, the blind is pulled back completely and usually wound up on a roll or at least deflected in the housing to be closed. A selective release of any section of the opening to be closed is not possible with a conventional blind closure of the type mentioned above.

In der EP-A-0 141 805 ist ein Rolladen der eingangs genannten Art beschrieben, bei dem die einzelnen Lamellen an ihren Längsenden jeweils an Zugketten um ihre Längsachse'drehbar gelagert sind. Die Lagerzapfen sind dabei mit einer Art Gewinde großer Steigung ausgebildet und greifen in eine komplementär geformte Lagerbohrung in der Kette. Werden die beiden Zugketten quer zu ihrer Längsrichtung in Richtung auf die Lamel-lenenden oder von diesen weg bewegt, so werden durch diese Bewegung sämtliche Lamellen um ihre Längsachse gedreht. Auf diese Weise können sämtliche Lamellen gleichzeitig zwischen einer erster Stellung, in der sie in einer Ebene liegen und die Jalousie geschlossen ist, und einer zweiten Stellung verstellt werden, in der sie quer zur Jalousieebene stehen und praktisch die gesamte von der Jalousie überdeckte Öffnung freigeben. Dabei bleiben die Lamellen der Jalousie jedoch ständig durch die Zugketten miteinander verbunden. Bei einer speziellen in der EP-A-141 805 beschriebenen Ausführungsform sind je zwei einander benachbarte Lamellen noch durch klauenartig ineinandergreifende Randabschnitte gegen ein Auseinanderhebeln der Lamellen gesichert. Um die Lamellen um ihre Längsachse verschwenken zu können, ist die Anordnung so getroffen, daß je zwei benachbarte Lamellen gegenläufig zueinander in Richtung ihrer Längsachsen verschoben werden können, bis die klauenartigen Randabschnitte außer Eingriff miteinander treten. Bei einer weiteren Verschiebung der Zugketten in der oben beschriebenen Weise werden wieder die Gewinde an den Lagerzapfen wirksam und führen zu einer Drehung der Lamellen um ihre Längsachse.EP-A-0 141 805 describes a roller shutter of the type mentioned in the introduction, in which the individual slats are rotatably mounted on their longitudinal ends on pull chains about their longitudinal axis. The trunnions are designed with a kind of thread with a large pitch and engage in a complementarily shaped bearing hole in the chain. If the two pull chains are moved transversely to their longitudinal direction in the direction of the slat ends or away from them, all slats are rotated about their longitudinal axis by this movement. In this way, all the slats can be adjusted simultaneously between a first position in which they lie in one plane and the blind is closed, and a second position in which they are transverse to the plane of the blind and expose practically the entire opening covered by the blind. However, the slats of the blind remain connected to each other by the pull chains. In a special embodiment described in EP-A-141 805, two mutually adjacent slats are still secured against prying apart of the slats by claw-like interlocking edge sections. In order to be able to pivot the slats about their longitudinal axis, the arrangement is such that two adjacent slats can be displaced in opposite directions to one another in the direction of their longitudinal axes until the claw-like edge sections disengage from one another. With a further displacement of the pull chains in the manner described above, the threads on the bearing pins become effective again and lead to a rotation of the slats about their longitudinal axis.

Eine selektive Freigabe eines beliebigen Abschnittes der zu verschließenden Öffnung ist jedoch auch bei dieser Jalousie nicht möglich.A selective release of any section of the opening to be closed is also not possible with this blind.

Der Erfindung liegt die Aufgabe zugrunde, einen Jalousieverschluß anzugeben, mit dem es möglich ist, innerhalb des von der gesamten Jalousie verschlossenen Öffnungsrahmens selektiv einen begrenzten Öffnungsausschnitt freizugeben, während die übrigen Teile der Öffnung verschlossen bleiben.The invention has for its object to provide a blind closure with which it is possible to selectively release a limited opening section within the opening frame closed by the entire blind, while the remaining parts of the opening remain closed.

Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Wird die Verbindung zwischen zwei benachbarten Lamellen gelöst, so bewegt sich bei einer Betätigung der Antriebsvorrichtung nur der mit dieser verbundene Jalousieabschnitt, während der entkoppelte Jalousieabschnitt stehen bleibt. Auf diese Weise entsteht zwischen den beiden ausgewählten entkoppelten Lamellen eine Öffnung, deren Breite von dem Verschiebeweg des mit der Antriebsvorrichtung verbundenen Jalousieabschnittes abhängt. Wie leicht einsehbar ist, kann diese Öffnung an beliebige Stellen der Jalousie verlegt werden, indem man an der betreffenden Stelle die einander benachbarten Lamellen entkoppelt. Der Verschiebeweg des mit der Antriebsvorrichtung verbundenen Jalousieabschnittes zur Freigabe der Teilöffnung ist dabei völlig unabhängig davon, wo diese Teilöffnung liegt oder wie lang die Jalousie ist. Dadurch ist es möglich, bei einer Jalousie beliebiger Länge eine Teilöffnung mit einer gewünschten Breite freizugeben, während der Rest der Öffnung verschlossen bleibt.If the connection between two adjacent slats is released, only the blind section connected to it moves when the drive device is actuated, while the decoupled blind section remains. In this way, an opening is created between the two selected decoupled slats, the width of which depends on the displacement path of the blind section connected to the drive device. As can be easily seen, this opening can be moved to any position on the blind by decoupling the adjacent slats at the relevant point. The displacement path of the blind section connected to the drive device to release the partial opening is completely independent of where this partial opening is or how long the blind is. This makes it possible to open a partial opening of a desired width in a blind of any length, while the rest of the opening remains closed.

Gemäß einer bevorzugten einfachen Ausführungsform ist an jeder Lamelle (mit Ausnahme einer Endlamelle) mindestens ein hakenförmiges Verbindungselement schwenkbar angeordnet, das zum Eingriff mit einem Gegenelement an der jeweils benachbarten Lamelle ausgebildet und durch die Betätigungsvorrichtung in seine Freigabestellung verschwenkbar ist. Vorzugsweise ist das Verbindungselement durch eine Rückstellfeder in seine Eingriffstellung vorgespannt, wobei es ferner mit einer Einweisungsfläche zum selbsttätigen Einrasten des Gegenelementes der jeweils benachbarten Lamelle versehen ist. Auf diese Weise brauchen die beiden Jalousieabschnitte zum Verschließen der Teilöffnung nur wieder zusammengeschoben werden, so daß das Verbindungselement in dem entsprechenden Gegenelement der benachbarten Lamelle einrastet. Eine besonders einfache Lösung ergibt sich, wenn die hakenförmigen Verbindungselemente jeweils an den Stirnflächen der Lamellen um zur Lamellenlängsrichtung parallele Achsen schwenkbar gelagert sind und das Gegenelement jeweils von einem ebenfalls an der Stirnfläche der jeweils benachbarten Lamelle angeordneten Zapfen gebildet ist. Wenn die Lamellen an ihren Stirnflächen mit Laufrollen versehen sind, kann beispielsweise die jeweilige Laufrollenachse als Gegenelement verwendet werden.According to a preferred simple embodiment, at least one hook-shaped connecting element is pivotally arranged on each lamella (with the exception of one end lamella), which is designed for engagement with a counter element on the respectively adjacent lamella and can be pivoted into its release position by the actuating device. The connecting element is preferably biased into its engagement position by a return spring, it also being provided with an instruction surface for the automatic engagement of the counter element of the respectively adjacent lamella. In this way, the two blind sections only need to be pushed together again to close the partial opening, so that the connecting element engages in the corresponding counter element of the adjacent slat. A particularly simple solution is obtained if the hook-shaped connecting elements are each pivotably mounted on the end faces of the slats about axes parallel to the longitudinal direction of the slats and the counter-element is in each case formed by a pin likewise arranged on the end face of the respectively adjacent slat. If the slats are provided with rollers on their end faces, the respective roller axle can be used as a counter element, for example.

Um zwei Lamellen der Jalousie an einer gewünschten Stelle selbsttätig entkoppeln zu können, ist erfindungsgemäß vorgesehen, daß die Betätigungsvorrichtung senkrecht zur Lamellenlängsrichtung und parallel zur Jalousieebene verstellbar ist und mindestens einen Betätigungshebel zum Verschwenken des Verbindungselementes in seine Freigabestellung aufweist. Auf diese Weise ist es möglich, ohne Eingriff von außen an einer gewünschten Stelle eine Teilöffnung freizugeben. Vorzugsweise ist der Betätigungshebel durch einen Elektromagneten gegen die Wirkung einer Rückstellfeder in seine Arbeitsstellung verstellbar.In order to be able to automatically decouple two slats of the blind at a desired location, the invention provides that the actuating device is adjustable perpendicular to the longitudinal direction of the slats and parallel to the plane of the blind and at least one actuating lever for pivoting the connecting element tes in its release position. In this way it is possible to open a partial opening at a desired location without external intervention. The actuating lever is preferably adjustable into its working position by an electromagnet against the action of a return spring.

Die Betätigungsvorrichtung kann einen mittels eines Positionierantriebes verstellbaren und an dem zu verschließenden Gehäuse geführten Schlitten umfassen, an dem der Betätigungshebel im wesentlichen senkrecht zur Jalousieebene geradlinig verstellbar gelagert ist, wobei der Betätigungshebel an seinem freien Ende einen Mitnehmer aufweist, der in der Arbeitsstellung des Betätigungshebels einen Fortsatz an dem Verbindungselement hintergreift. Die Betätigungsvorrichtung wird also mit Hilfe des Schlittens bis auf die Höhe der Lamelle gefahren, an der das Verbindungselement in seine Freigabestellung verschwenkt werden soll. Nach Erreichen dieser Position wird der Betätigungshebel bewegt und dadurch das Verbindungselement verschwenkt. Der Positionierantrieb umfaßt zweckmäßigerweise einen Elektromotor, der beispielsweise über einen Zahnriemen oder dergleichen den Schlitten bewegt, wobei die Position mit Hilfe eines Codierlineals bestimmbar ist, das beispielsweise codierte Öffnungen aufweist, die mittels einer optoelektronischen Abtastvorrichtung abtastbar sind.The actuating device can comprise a slide adjustable by means of a positioning drive and guided on the housing to be closed, on which the actuating lever is mounted such that it can be adjusted in a straight line substantially perpendicular to the plane of the blind, the actuating lever having at its free end a driver which, in the operating position of the actuating lever, has a driver Extension extends behind the connecting element. The actuating device is thus moved with the aid of the slide to the height of the lamella at which the connecting element is to be pivoted into its release position. After reaching this position, the actuating lever is moved and the connecting element is thereby pivoted. The positioning drive expediently comprises an electric motor which, for example, moves the slide via a toothed belt or the like, the position being determinable with the aid of a coding ruler which, for example, has coded openings which can be scanned by means of an optoelectronic scanning device.

Für den Fall, daß die Teilöffnung nur relativ schmal zu sein braucht und somit der mit der Antriebsvorrichtung verbundene Jalousieabschnitt nur um ein kurzes Stück verschoben zu werden braucht, wird erfindungsgemäß vorgeschlagen, daß die an einer Endlamelle der Jalousie angreifende Antriebsvorrichtung eine um eine erste ortsfeste Achse drehfest gelagerte und durch einen Stellmotor antreibbare Kurbel sowie einen zweiarmigen Hebel umfaßt, der um eine zweite ortsfeste Achse schwenkbar gelagert und mit seinem einen Ende an der Endlamelle angelenkt und mit seinem anderen Ende über einen Doppellenker mit der Kurbel verbunden ist, wobei die Endlamelle mit ihren Laufrollen in einer der Bewegung des zweiarmigen Hebels angepaßten Schiene geführt ist. Dieser Antrieb ermöglicht eine Zwangsbewegung des mit der Antriebsvorrichtung verbundenen Jalousieabschnittes in beiden Richtungen. Vorzugsweise ist der Stellmotor dabei so gesteuert, daß die Kurbel für die Öffnungs- und Schließbewegung der Jalousie jeweils eine halbe Umdrehung durchführt. Dies ermöglicht bei der vorbeschriebenen Antriebsvorrichtung eine Verstellung der Jalousie in beiden Richtungen bei gleichbleibender Drehrichtung des Stellmotors. Dadurch vereinfacht sich die Steuerung des Stellmotors. Die Steuerung des Stellmotors für eine Drehbewegung der Kurbel in Schritten von jeweils 180° läßt sich auf einfache Weise dadurch erreichen, daß auf einer mit der Kurbel drehfest verbundenen und durch den Stellmotor drehbaren Welle mindestens eine Nockenscheibe angeordnet ist, die mit einem Schalter zur Steuerung des Stellmotors zusammenwirkt.In the event that the partial opening need only be relatively narrow and thus the blind section connected to the drive device only needs to be moved a short distance, it is proposed according to the invention that the drive device engaging an end lamella of the blind has a fixed axis about a first rotatably mounted and driven by a servomotor crank and a two-armed lever, which is pivotally mounted about a second fixed axis and articulated at one end to the end plate and at the other end via a double link to the crank, the end plate with their Rollers is guided in a rail adapted to the movement of the two-armed lever. This drive enables a forced movement of the blind section connected to the drive device in both directions. The servomotor is preferably controlled in such a way that the crank makes half a turn for the opening and closing movement of the blind. With the drive device described above, this enables the blind to be adjusted in both directions while the direction of rotation of the servomotor remains the same. This simplifies the control of the servomotor. The control of the servomotor for a rotary movement of the crank in steps of 180 ° can be achieved in a simple manner in that at least one cam disk is arranged on a shaft which is connected in a rotationally fixed manner to the crank and rotatable by the servomotor and which is equipped with a switch for controlling the Servomotor interacts.

Der vorstehend beschriebene Jalousieverschluß ist besonders geeignet für Wertscheinbehälter mit einer Vielzahl von einzelnen Fächern, von denen jeweils nur das Fach geöffnet und freigegeben werden soll, zu dem gerade ein Zugriff erwünscht ist. Die Betätigungsvorrichtung und der Stellmotor zum Verstellen des jeweils zu verschiebenden Jalousieabschnittes können elektronisch angesteuert werden, so daß das Öffnen und Schließen des Jalousieverschlusses an der gewünschten Stelle völlig selbsttätig erfolgen kann. Das Öffnen und Schließen des Verschlusses geht relativ rasch, da der mit der Antriebsvorrichtung verbundene Jalousieabschnitt unabhängig von dem Ort der jeweiligen Teilöffnung immer nur um eine relativ kurze Strecke verschoben werden muß.The above-described blind closure is particularly suitable for note receptacles with a large number of individual compartments, of which only the compartment to which access is desired is to be opened and released. The actuating device and the servomotor for adjusting the respective blind section to be displaced can be controlled electronically, so that the opening and closing of the blind lock can take place completely automatically at the desired point. The opening and closing of the closure is relatively quick, since the blind section connected to the drive device always has to be displaced only a relatively short distance regardless of the location of the respective partial opening.

In Fig. 1 erkennt man einen allgemein mit 10 bezeichneten Behälter mit einem Gehäuse 12, das an seiner Deckfläche 14 eine Öffnung 16 aufweist, die mit der erfindungsgemäßen Jalousie 18 verschließbar ist. Der Behälter '10 dient zur Aufnahme eines Einschubes 20 mit einzelnen Fächern 22, die an ihren oberen Enden offen sind und zur Aufnahme von Banknoten dienen. Der Einschub 20 wird durch eine verschwenkbare Gehäuseklappe 24 auf Winkelschienen 26 eines innerhalb des Gehäuses 12 angeordneten Behältergestelles 28 eingeschoben, das nur so weit dargestellt ist und beschrieben wird, wie es zur Erläuterung der Lagerung und Betätigung der Jalousie 18 erforderlich ist. Der Behälter 10 soll im vorliegenden Fall beispielsweise zur Aufbewahrung von Banknoten an einem Bankschalter dienen, wobei die Jalousie 18 so ausgebildet ist, daß sie jeweils nur den Zugriff zu einem der Fächer 22 freigibt. Außer durch Öffnen der absperrbaren Klappe 24 soll es nicht möglich sein, sämtliche Fächer 22 gleichzeitig zum Zugriff freizugeben. Der Aufbau und die Funktionsweise der Jalousie 18, die diese Aufgabe erfüllt, wird nun im folgenden erläutert.In Fig. 1 you can see a generally designated 10 container with a housing 12 which has an opening 16 on its top surface 14, which can be closed with the blind 18 according to the invention. The container '10 serves to receive an insert 20 with individual compartments 22 which are open at their upper ends and serve to receive banknotes. The insert 20 is inserted through a pivotable housing flap 24 onto angle rails 26 of a container frame 28 arranged within the housing 12, which is only shown and described as far as is necessary to explain the storage and actuation of the blind 18. In the present case, the container 10 is intended, for example, to store banknotes at a bank counter, the blind 18 being designed in such a way that it only allows access to one of the compartments 22. Except by opening the lockable flap 24, it should not be possible to release all compartments 22 for access at the same time. The structure and the mode of operation of the blind 18, which fulfills this task, will now be explained in the following.

Gemäß Fig. 2 besteht die Jalousie 18 aus einzelnen Lamellen 30, die entlang ihrer Längskanten sich teilweise überlappend miteinander verbindbar sind. Jede Lamelle 30 trägt an ihren Stirnflächen 32 Laufrollen 34, die in einem Abstand von der jeweiligen Stirnfläche 32 um eine. zur Lamellenlängsrichtung parallele Achse 36 frei drehbar gelagert sind. Mit den Laufrollen 34 sind die Lamellen in C-förmigen Schienen 38 geführt, die entlang den Längsrändern der Gehäuseöffnung 16 an dem Behälterrahmen 28 befestigt sind (Fig. 1).2, the blind 18 consists of individual slats 30 which partially overlap with one another along their longitudinal edges are connectable. Each lamella 30 carries on its end faces 32 rollers 34 which are at a distance from the respective end face 32 by one. axis 36 parallel to the slat longitudinal direction are freely rotatable. With the rollers 34, the lamellae are guided in C-shaped rails 38 which are fastened to the container frame 28 along the longitudinal edges of the housing opening 16 (FIG. 1).

Zwischen den beiden Laufrollen 34 ist an den Stirnflächen 32 jeder Lamelle 30 jeweils ein allgemein mit 40 bezeichnetes Verbindungselement auf einem Zapfen 42 um eine zur Lamellenlängsrichtung parallele Schwenkachse 44 schwenkbar gelagert. Das Verbindungselement 40 besitzt ein Z-Profil (siehe Fig. 3) mit einem ersten parallel zur Stirnfläche 32 der Lamelle 30 gerichteten Schenkel 46, einem rechtwinklig von diesem nach außen abstehenden Schenkel 48 und einem sich an diesen anschließenden parallel zum ersten Schenkel 46, jedoch nach der entgegengesetzten Seite gerichteten dritten Schenkel 50. Der erste Schenkel 46 ist in Form eines um die Achse 44 verschwenkbaren Hakens mit einer Hakenöffnung 52 ausgebildet, die zum Umgreifen des Lagerzapfens 54 der Laufrolle 34 einer benachbarten Lamelle 30 bestimmt ist, wie dies in Fig. 2 dargestellt ist. Das Verbindungselement wird dabei durch eine Torsionsfeder 56 in die in der Fig. 2 für das rechte Verbindungselement dargestellte Verbindungs- oder Verriegelungsstellung vorgespannt. Aus dieser Verriegelungsstellung kann das jeweilige Verbindungselement 40 gegen die Rückstellkraft der Torsionsfeder 56 in die in der Fig. 2 durch strichpunktierte Linien wiedergegebene Freigabestellung verschwenkt werden, in welcher der Zapfen 54 außer Eingriff mit der Hakenöffnung 52 tritt, so daß die einander benachbarten und vorher durch die Verbindungselemente 40 miteinander verbundenen Lamellen 30 nun entkoppelt sind. Im folgenden soll nun die zur Entkoppelung der Lamellen. dienende allgemein mit 58 bezeichnete Betätigungsvorrichtung insbesondere anhand der Fig. 1 und 3 beschrieben werden.Between the two rollers 34 on the end faces 32 of each lamella 30 there is in each case a connecting element, generally designated 40, on a pin 42 which is pivotable about a pivot axis 44 parallel to the longitudinal direction of the lamella. The connecting element 40 has a Z-profile (see FIG. 3) with a first leg 46 directed parallel to the end face 32 of the lamella 30, a leg 48 protruding at right angles therefrom and an adjoining leg 48 parallel to the first leg 46, however to the opposite side directed third leg 50. The first leg 46 is designed in the form of a pivotable about the axis 44 hook with a hook opening 52, which is intended to engage around the bearing pin 54 of the roller 34 of an adjacent lamella 30, as shown in Fig. 2 is shown. The connecting element is prestressed by a torsion spring 56 in the connecting or locking position shown in FIG. 2 for the right connecting element. From this locking position, the respective connecting element 40 can be pivoted against the restoring force of the torsion spring 56 into the release position shown by dash-dotted lines in FIG. 2, in which the pin 54 disengages from the hook opening 52, so that the adjacent and previously through the connecting elements 40 interconnected slats 30 are now decoupled. In the following, the decoupling of the slats will now be described. serving generally designated 58 actuator described in particular with reference to FIGS. 1 and 3.

Die Betätigungsvorrichtung umfaßt einen Schlitten 60, der sich in Lamellenlängsrichtung quer über die Behälterbreite erstreckt und auf einer senkrecht zur Lamellenlängsrichtung verlaufenden Führungsstange 62 verschiebbar geführt ist. Ferner ist der Schlitten 60 an seinen beiden Längsenden jeweils über eine Rolle 64 auf einer Stützschiene 66 abgestützt. Zum Antrieb des Schlittens dient ein in beiden Richtungen antreibbarer Elektromotor 68, der über Zahnriemen 70 und 72 den Schlitten entlang der Führungsstange 62 und somit quer zur Lamellenlängsrichtung verfahren kann.The actuating device comprises a slide 60 which extends across the width of the container in the longitudinal direction of the slats and is displaceably guided on a guide rod 62 running perpendicular to the longitudinal direction of the slats. Furthermore, the carriage 60 is supported at its two longitudinal ends by a roller 64 on a support rail 66. The carriage is driven by an electric motor 68 which can be driven in both directions and which can move the carriage along toothed belts 70 and 72 along the guide rod 62 and thus transversely to the longitudinal direction of the slats.

Der Schlitten trägt an seinen beiden Längsenden jeweils eine vertikal gerichtete Stütze 74, an der ein Betätigungshebel 76 senkrecht zur Ebene der Jalousie 18 geradlinig verschiebbar geführt ist. Die Führung erfolgt über zwei Stifte 78, die entsprechende Langlöcher 80 in dem Betätigungshebel 76 durchsetzen. An seinem unteren Ende ist der Betätigungshebel 76 mit dem Anker 82 eines Elektromagneten 84 verbunden, so daß der Betätigungshebel 76 bei Bestromung des Elektromagneten 84 nach unten gezogen wird. Durch eine Rückstellfeder 86, die einerseits an dem oberen Zapfen 78 und andererseits an einer Nase 88 des Betätigungshebels 76 angreift, wird dieser beim Ausschalten des Elektromagneten 84 nach oben in seine Ausgangsstellung zurückgezogen. Der Betätigungshebel 76 weist an seinem oberen Ende einen in Form einer rechtwinklig abgebogenen Klaue 90 ausgebildeten Mitnehmer auf, der eine Rolle 92 übergreift, die an dem Schenkel 50 des Verbindungselementes 40 um eine zur Lamellenlängsrichtung parallele Achse 94 drehbar gelagert ist. Wird der Betätigungshebel 76 durch den Elektromagneten 84 nach unten verstellt, drückt der Mitnehmer 90 auf die Rolle 92, wobei das Verbindungselement 40 um die Achse 44 verschwenkt und dadurch die Verbindung zwischen zwei benachbarten Lamellen 30 gelöst wird. Die beiden Stellungen des Betätigungshebels 76 und die korrespondierenden Stellungen des Verbindungselementes 40 sind in Fig. 2 durch ausgezogene bzw. strichpunktierte Linien dargestellt.The carriage carries at each of its two longitudinal ends a vertically directed support 74, on which an actuating lever 76 is guided so as to be linearly displaceable perpendicular to the plane of the blind 18. The guide takes place via two pins 78 which pass through corresponding elongated holes 80 in the actuating lever 76. At its lower end, the actuating lever 76 is connected to the armature 82 of an electromagnet 84, so that the actuating lever 76 is pulled downward when the electromagnet 84 is energized. By means of a return spring 86, which acts on the one hand on the upper pin 78 and on the other hand on a lug 88 of the actuating lever 76, the latter is retracted upward into its starting position when the electromagnet 84 is switched off. The actuating lever 76 has at its upper end a driver designed in the form of a claw 90 bent at right angles, which engages over a roller 92 which is rotatably mounted on the leg 50 of the connecting element 40 about an axis 94 parallel to the longitudinal direction of the slats. If the actuating lever 76 is adjusted downward by the electromagnet 84, the driver 90 presses on the roller 92, the connecting element 40 being pivoted about the axis 44 and the connection between two adjacent slats 30 being thereby released. The two positions of the actuating lever 76 and the corresponding positions of the connecting element 40 are shown in FIG. 2 by solid or dash-dotted lines.

Zur Lösung der Verbindung zwischen zwei ausgewählten benachbarten Lamellen 30 genügt es also, die Betätigungsvorrichtung 58 entlang der Führungsstange 62 in die gewünschte Stellung unter den ausgewählten Lamellen zu fahren, so daß der Mitnehmer 90 die Rolle 92 des betreffenden Verbindungselementes 40 übergreift. Anschließend wird der Elektromagnet 84 betätigt. Um die Betätigungsvorrichtung 58 in die gewünschte Position zu bringen, ist ein Codierlineal 96 vorgesehen, das den möglichen Stellungen des Schlittens 60 entsprechende nicht dargestellte Codieröffnungen aufweist, die mittels einer ebenfalls nicht dargestellten optoelektronischen Abtastvorrichtung abgetastet werden können. Die Verstellung des Betätigungshebels kann auch durch andere Mittel, z. B. durch einen Motor und ein geeignetes Getriebe erfolgen.To solve the connection between two selected adjacent slats 30, it is therefore sufficient to move the actuating device 58 along the guide rod 62 into the desired position under the selected slats, so that the driver 90 engages over the roller 92 of the connecting element 40 in question. The electromagnet 84 is then actuated. In order to bring the actuating device 58 into the desired position, a coding ruler 96 is provided which has coding openings (not shown) corresponding to the possible positions of the carriage 60, which can be scanned by means of an optoelectronic scanning device (also not shown). The adjustment of the actuating lever can also be done by other means, e.g. B. done by a motor and a suitable gear.

Um nun den Zugriff zu dem ausgewählten Fach 22 freizugeben, muß nach dem Lösen der Verbindung zwischen zwei einander benachbarten Lamellen 30 einer der zusammenhängenden Jalousieabschnitte um eine Fachbreite verschoben werden. Hierzu dient eine an einer Endlamelle 30' angreifende Antriebsvorrichtung, die nun anhand der Fig. 2 und 4 näher erläutert werden soll.In order to now allow access to the selected compartment 22, one of the contiguous blind sections must be displaced by a compartment width after the connection between two adjacent slats 30 has been released. For this purpose, a drive device acting on an end lamella 30 ′ is used, which will now be explained in more detail with reference to FIGS. 2 and 4.

An einer Traverse 98 des Behälterrahmens 28 ist mit Hilfe von Stützen 100 eine in Lamellenlängsrichtung gerichtete Welle 102 gelagert. Diese Welle trägt an ihren beiden Enden jeweils eine Kurbel- oder Exzenterscheibe 104, die über einen an einem exzentrischen Zapfen 106 der Kurbelscheibe 104 angelenkten Doppellenker 108 mit dem einen Ende eines zweiarmigen Hebels 110 gelenkig verbunden ist. Dieser ist um eine zur Welle 102 parallele Welle 112 schwenkbar gelagert und mit seinem anderen Ende an der Stirnfläche 32' der Endlamelle 30' angelenkt.A shaft 102 directed in the longitudinal direction of the slats is mounted on a crossbar 98 of the container frame 28 with the aid of supports 100. This shaft has a crank or eccentric disk 104 at its two ends, which is articulated to one end of a two-armed lever 110 via a double link 108 articulated on an eccentric pin 106 of the crank disk 104. This is pivotally mounted about a shaft 112 parallel to the shaft 102 and is hinged at its other end to the end face 32 'of the end plate 30'.

Die Welle 102 wird über einen Elektromotor 114 angetrieben, dessen Antriebsritzel 116 mit einem auf der Welle 102 drehfest angeordneten Zahnrad 118 kämmt. Auf der Welle 102 sind ferner zwei Nockenscheiben 120 und 122 drehfest angeordnet, die mit zwei rahmenfesten Schaltern 124, 126 zusammenwirken, welche das Ein- und Ausschalten des Motors 114 steuern.The shaft 102 is driven by an electric motor 114 driven, the drive pinion 116 meshes with a gear 118 arranged on the shaft 102 rotatably. Furthermore, two cam disks 120 and 122 are arranged on the shaft 102 in a rotationally fixed manner, which interact with two switches 124, 126 which are fixed to the frame and which control the switching on and off of the motor 114.

Wird nach dem Lösen der Verbindung zwischen zwei benachbarten Lamellen 30 die Kurbelscheibe 104 in Richtung des Pfeiles C in Fig. 2 durch Einschalten des Motors 114 gedreht, so wird der zweiarmige Hebel 110 aus der in der Fig. 2 mit ausgezogenen Linien dargestellten Stellung in die strichpunktiert eingezeichnete Stellung verschwenkt, wobei die Endlamelle 30' und die mit ihr noch verbundenen weiteren Lamellen 30 in der Fig. 2 nach links verschoben werden. Die Endlamelle 30' ist dabei mit ihren Laufrollen 34' in einem abgebogenen Abschnitt 38' der Laufschiene 38 geführt, so daß die Endlamelle 30' der Schwenkbewegung des zweiarmigen Hebels 110 folgen kann. Die Hebellängen und der Kurbelradius der Kurbelscheibe 104 sind so gewählt, daß bei einer Drehung der Kurbelscheibe um 180° die . Endlamelle 30' und die mit ihr zusammenhängenden weiteren Lamellen 30 gerade um eine Fachbreite verschoben werden. Dieser Verschiebeweg bleibt stets gleich unabhängig davon, an welcher Stelle die Jalousie die Verbindung zwischen den Lamellen 30 unterbrochen wird und eine Fachöffnung freigegeben werden soll.If, after releasing the connection between two adjacent lamellae 30, the crank disk 104 is rotated in the direction of arrow C in FIG. 2 by switching on the motor 114, the two-armed lever 110 is moved from the position shown in solid lines in FIG Position shown in dash-dotted lines pivoted, the end lamella 30 'and the further lamella 30 still connected to it being shifted to the left in FIG. 2. The end plate 30 'is guided with its rollers 34' in a bent section 38 'of the running rail 38, so that the end plate 30' can follow the pivoting movement of the two-armed lever 110. The lever lengths and the crank radius of the crank disk 104 are selected so that when the crank disk rotates through 180 °, the. End lamella 30 'and the associated further lamella 30 are just shifted by a compartment width. This displacement path always remains the same regardless of the point at which the blinds the connection between the slats 30 is interrupted and a compartment opening is to be released.

Wird die Kurbelscheibe 104 in Richtung des Pfeiles C aus der in der Fig. 2 durch strichpunktierte Linien wiedergegebenen Stellung weitergedreht, so wird der zweiarmige Hebel 110 wieder in der Gegenrichtung verschwenkt und schiebt die Endlamelle 30' zusammen mit den ihr benachbarten Lamellen in die Ausgangslage zurück. Diese Zwangsbewegung der Endlamelle 30' wird durch die schräge Rampe an dem abgesenkten Schienenabschnitt 38' erleichtert. Die schräge Rampe bewirkt ferner, daß beim Öffnen der Jalousie die Endlamelle 30' etwas abgesenkt und dadurch eine unbeabsichtigte Entkopplung der benachbarten Lamelle 30 verhindert wird. Wenn die beiden Lamellen 30, zwischen denen die Verbindung gelöst worden war, wieder aneinander anliegen, wird der Elektromagnet 84 ausgeschaltet, worauf das Verbindungselement 40 durch die Rückstellfeder 56 in seine Ausgangslage zurückgeführt wird, in der es den jeweiligen Zapfen 54 an der Nachbarlamelle umgreift. Gegebenenfalls kann die Anordnung auch so getroffen sein, daß der Elektromagnet 84 nach der Freigabe der Fachöffnung augeschaltet wird, wodurch das Verbindungselement 40 in seine Ruhelage zurückkehrt. In diesem Falle sollte das Verbindungselement 40 mit Einweisungsflächen versehen sein, so daß der Zapfen 54 der Nachbarlamelle beim Zusammenschieben der beiden Jalousieabschnitte in die Hakenöffnung 52 selbsttätig einrastet.If the crank disk 104 is rotated further in the direction of arrow C from the position shown by dash-dotted lines in FIG. 2, the two-armed lever 110 is pivoted again in the opposite direction and pushes the end plate 30 'together with the adjacent plates back into the starting position . This forced movement of the end lamella 30 'is facilitated by the inclined ramp on the lowered rail section 38'. The inclined ramp also has the effect that the end lamella 30 'is lowered somewhat when the blind is opened, thereby preventing inadvertent decoupling of the adjacent lamella 30. When the two lamellae 30, between which the connection has been released, are in contact again, the electromagnet 84 is switched off, whereupon the connecting element 40 is returned to its starting position by the return spring 56, in which it engages around the respective pin 54 on the neighboring lamella. If necessary, the arrangement can also be such that the electromagnet 84 is switched off after the compartment opening has been released, as a result of which the connecting element 40 returns to its rest position. In this case, the connecting element 40 should be provided with instruction surfaces so that the pin 54 of the neighboring slat automatically engages in the hook opening 52 when the two blind sections are pushed together.

Das vorstehende Ausführungsbeispiel zeigt die erfindungsgemäße Jalousie in Verbindung mit einem Behälter für Wertscheine oder Banknoten. Es versteht sich, daß dieser Jalousieverschluß überall dort Verwendung finden kann, wo nur eine Teilöffnung einer durch die Jalousie insgesamt verschließbaren Öffnung freigegeben werden soll, wie z. B. bei Warenausgabeautomaten und dgl. Die Verbindungselemente und die Betätigungsvorrichtung wurden nur auf einer Seite der Jalousie dargestellt und beschrieben. Es versteht sich, daß die Verbindungselemente auf beiden Stirnflächen der Lamellen angeordnet sein können, so wie dies in Fig. 2 andeutungsweise erkennbar ist. Entsprechend muß auf der anderen Jalousieseite auch ein Betätigungshebel vorgesehen sein.The above embodiment shows the blind according to the invention in connection with a container for notes or banknotes. It goes without saying that this blind closure can be used wherever only a partial opening of an opening that can be closed by the blind as a whole is to be released, such as, for. B. in goods dispensing machines and the like. The connecting elements and the actuating device were shown and described only on one side of the blind. It goes without saying that the connecting elements can be arranged on both end faces of the slats, as can be seen in FIG. 2. Accordingly, an operating lever must also be provided on the other side of the blind.
