Description

Die Erfindung betrifft einen jalousierbaren Rolladen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a Venetian blinds according to the preamble of claim 1.

Bei jalousierbaren Rolladen sind die einzelnen Rolladenstäbe gelenkig mit Zug- und Verstellkettengliedern verbunden, so daß die Rolladenstäbe aus einer Rolladenstellung, in welcher durch die Rolladenstäbe die dahinter befindliche Öffnung voll geschlossen bzw. abgedeckt ist, in eine Jalousie-Stellung verschwenkbar sind, in welcher die Durchsicht zwischen den derart verschwenkten Rolladenstäben möglich ist. Aufgrund der für die Verschwenkung dieser Rolladenstäbe erforderlichen Jalousiereinrichtung bedarf es zumeist spezieller Führungsschienen für den Einbau der Rolladen. Diese Führungsschienen müssen in der Regel breiter als die von normalen Rolladen dimensioniert sein, um die für die Verschwenkung der Rolladenstäbe erforderliche Jalousiereinrichtung bzw. Teile hiervon, unterbringen zu können. Dies hat zur Folge, daß eine Nachrüstung von bereits in Bauwerken vorhandenen normalen Rolladen durch jalousierbare Rolladen nur schwer möglich ist, weil die ortsfest vorhandenen Rahmen und Führungen durch solche mit größeren Abmessungen ersetzt werden müssen. Es liegt auf der Hand, daß es zweckmäßig wäre, derartige jalousierbare Rolladen so auszubilden, daß sie in bereits vor Ort vorhandene Führungsschienen oder Führungsprofile für normale Rolladen ohne Jalousiereinrichtung einbaubar sind.In roller shutters that can be louvered, the individual roller shutter slats are connected in an articulated manner to tension and adjustment chain links, so that the roller shutter slats can be pivoted from a roller shutter position, in which the opening behind them is fully closed or covered, into a blind position, in which the View between the roller shutter slats pivoted in this way is possible. Due to the blind device required for pivoting these roller shutter slats, special guide rails are usually required for the installation of the roller shutters. These guide rails usually have to be wider than those of normal roller shutters in order to be able to pivot the Roller shutter slats required to accommodate Venetian blind device or parts thereof. The consequence of this is that it is difficult to retrofit normal roller shutters already present in buildings with blinds that can be shut, because the frames and guides that are present in a fixed position have to be replaced by those with larger dimensions. It is obvious that it would be expedient to design roller shutters of this type in such a way that they can be installed in guide rails or guide profiles already present on site for normal roller shutters without a blind device.

Jalousierbare Rolladen, die eine solche Umrüstung vorhandener Anlagen ermöglichen, sind bereits aus FR-A- 2 553 467 und bekannt (EP-A-0 189 091). Gemäß der EP-A- 0 189 091 sind die jalousierbaren Rolladenstäbe an ihren oberen Enden durch Zugkettenglieder und an ihren unteren Enden durch Verstellkettenglieder verbunden. Die Zugkettenglieder und die Verstellkettenglieder sind hierbei an einem Ende in Art eines Auges und am anderen Ende in Art einer Gabel ausgebildet, so daß benachbarte Kettenglieder scharnierartig zusammengesetzt werden können. Zwischen je einem Paar von benachbarten Zug-und Verstellkettengliedern sind hierbei die Rolladenstäbe aufgenommen. Alleine diese Bauart macht es bereits unmöglich, die Rollädenstäbe in eine geschlossene Nut/Feder-Position zu verfahren, wo die in einem Rolladenstab ausgebildete Feder in eine am benachbarten Rolladenstab ausgebildete Nut zur Bildung eines einbruchssicheren Rolladenverschlusses einfahrbar ist.Roller shutters which can be blinded and which enable such retrofitting of existing systems are already known from FR-A-2 553 467 and (EP-A-0 189 091). According to EP-A-0 189 091, the blindable roller shutter slats are connected at their upper ends by pull chain links and at their lower ends by adjustable chain links. The pull chain links and the adjustment chain links are designed at one end in the manner of an eye and at the other end in the manner of a fork, so that adjacent chain links can be assembled in a hinge-like manner. The roller shutter slats are accommodated between a pair of adjacent tension and adjustment chain links. This type of construction alone makes it impossible to move the roller shutter slats into a closed tongue and groove position, where the tongue formed in a roller shutter slat can be moved into a groove formed on the adjacent roller shutter slat to form a burglar-proof roller shutter lock.

Ferner benötigt der bekannte jalousierbare Rolladen zu den beiden Ketten aus Zug- und Verstellkettengliedern eine weitere randseitig an den Rolladenstäben vorgesehene Kette aus Führungskettengliedern, die in den ortsfest eingebauten Führungsprofilen geführt sind. Die Führungskettenglieder sind als Schlitzkettenglieder ausgebildet und untereinander durch Schlitzbuchsen, also mit einem Längsschlitz versehene Buchsen scharnierartig verbunden. Die Aufhängung der Rolladenstäbe erfolgt über einen Gelenkbolzen, der axial mit den entsprechend zu gestaltenden Schlitzbuchsen der Führungskettenglieder auszurichten ist. Hierbei sind die Schlitzbuchsen als Verbindungselemente für die Führungskettenglieder festigkeitsmäßig so auszulegen, daß sie den Belastungen aus den darunterliegenden Kettengliedern und den darunter sich befindlichen Rolladenstäben standhalten können. Ferner sind die Schlitzbuchsen so auszulegen, daß sie die Gelenkbolzen für die Anlenkung der Rolladenstäbe aufnehmen können. Eine weitere Funktion, die diese Schlitzbuchsen zu erfüllen haben, besteht darin, daß die Schlitzbuchsen beim Übergang aus der Rolladenstellung in die Jalousierstellung ein Einfahren der Gelenkbolzen für die Aufhängung der Rolladenstäbe in die Schlitze der Schlitzkettenglieder ermöglichen müssen. Somit muß die Verbindung der Führungskettenglieder entsprechend den verschiedenen Funktionen ausgelegt werden, was kompliziert ist und es fürderhin erschwert, derartig gestaltete Führungskettenglieder in vorhandene Führungsschienen für normale Rolladen unterzubringen. Ein weiterer Nachteil ist darin zu sehen, daß die Gelenkstellen für die Anlenkung der Rolladenstäbe an den Führungskettengliedern axial mit den Achsen der Schlitzbuchsen ausgerichtet sein müssen, woraus sich wiederum bauliche Beschränkungen für die Rolladenkonstruktion ergeben. Für den Übergang aus der Rolladenstellung in die Jalousierstellung sind zudem an den Rolladenstäben und an den Führungskettengliedern entsprechende Anschläge auszubilden, ebenso wie an einer speziell am untersten Rolladenstab vorzusehenden Ausstellstütze. Insgesamt ist der bekannte jalousierbare Rolladen kompliziert aufgebaut und es sind auch Fehlfunktionen nicht ausgeschlossen. Auch der Wickelumfang aufgrund der auf der Vorderfläche und auf der Rückfläche der Rolladenstäbe auftragenden Verstell- und Zugkettenglieder ist vergleichsweise groß. Ein weiterer Nachteil besteht darin, daß aufgrund der drei Ketten und der im wesentlichen bandartigen Ausbildung der Zug- und Verstellkettenglieder sich eine Begrenzung der verfügbaren lichten Weite für den jalousierfähigen bzw. für die Durchsicht verfügbaren Bereich ergibt.Furthermore, the known blinds for the two chains consisting of tension and adjustment chain links require a further chain of guide chain links provided on the edge of the roller shutter bars, which are guided in the fixed guide profiles. The guide chain links are designed as slot chain links and are connected to one another in a hinge-like manner by slot bushings, that is to say bushes provided with a longitudinal slot. The roller shutter slats are suspended by means of a hinge pin, which corresponds axially with the to align slot bushings of the guide chain links. Here, the slotted bushings are designed as connecting elements for the guide chain links so that they can withstand the loads from the chain links underneath and the roller shutter bars underneath. Furthermore, the slot bushings are to be designed so that they can accommodate the hinge pins for the articulation of the roller shutter slats. Another function that these slotted sleeves have to fulfill is that the slotted sleeves must enable the pivot pins for the suspension of the shutter slats to be inserted into the slits of the slotted chain links during the transition from the roller shutter position to the blind position. Thus, the connection of the guide chain links must be designed according to the various functions, which is complicated and, moreover, makes it difficult to accommodate guide chain links designed in this way in existing guide rails for normal roller shutters. Another disadvantage is the fact that the articulation points for the articulation of the roller shutter bars on the guide chain links must be aligned axially with the axes of the slot bushings, which in turn results in structural restrictions for the roller shutter construction. For the transition from the roller shutter position to the blind position, appropriate stops must also be formed on the roller shutter bars and on the guide chain links, as well as on an extension support to be provided on the lowest roller shutter bar. Overall, the well-known Venetian blinds have a complicated structure and malfunctions are not excluded. The winding circumference is also comparatively large due to the adjustment and pull chain links applied to the front surface and to the rear surface of the roller shutter bars. Another disadvantage is that due to the three chains and the essentially band-like design of the pulling and adjusting chain links, there is a limitation in the available clear width for the blind-capable or for the viewing area.

Aufgabe der Erfindung ist es, eine jalousierbare Rollade zu schaffen, welche einfach und robust aufgebaut ist sowie eine zuverlässige Jalousierung ermöglicht. Ferner soll sich der Rolladen ohne Schwierigkeiten in vorhandene Führungsprofile für normale Rolladen unterbringen lassen und beim Aufwickeln einen mit einem normalen Rolladen vergleichbaren Wickeldurchmesser aufweisen.The object of the invention is to provide a roller shutter which is simple and robust and which enables reliable shuttering. Furthermore, the roller shutter should be able to be accommodated in existing guide profiles for normal roller shutters without difficulty and should have a winding diameter comparable to that of a normal roller shutter during winding.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 enthaltenen Merkmale gelöst, wobei zweckmäßige Weiterbildungen der Erfindung durch die in den Unteransprüchen enthaltenen Merkmale gekennzeichnet sind.This object is achieved by the features contained in the characterizing part of claim 1, expedient developments of the invention being characterized by the features contained in the subclaims.

Nach der Erfindung sind die Zugkettenglieder und die Verstellkettenglieder seitlich an den beiden Enden eines jeden Rolladenstabs angeordnet und zwar nebeneinander sowie in Flucht untereinander, so daß die Kettenglieder praktisch eine seitliche Verlängerung der Rolladenstäbe darstellen. Dadurch bauen die Rolladenstäbe an der Vorder- und an der Rückfläche nicht um die Dicke bzw. Stärke der Kettenglieder auf, was sich günstig für den Wickeldurchmesser des jalousierbaren Rolladens auswirkt. Sind die Zugkettenglieder und Verstellkettenglieder in ihrer Querschnittsabmessung der Querschnittsabmessung des Rolladenstabs angepaßt und verlaufen sie somit im wesentlichen bündig mit der Vorder- und Rückfläche der Rolladenstäbe, so ergibt sich praktisch derselbe Wickeldurchmesser wie bei einem normalen Rolladen ohne Jalousiereinrichtung. Infolge der seitlichen Anordnung der Kettenglieder in Flucht mit den Rolladenstäben entfällt eine Überdeckung der Rolladenstäbe durch die Kettenglieder, was eine Maximierung der lichten Weite des jalousierbaren Öffnungsbereiches erlaubt. Diese Optimierung kommt insbesondere zum Tragen, wenn mindestens die Verstellkettenglieder schmal in Art von Lamellen ausgeführt werden. Ferner können die Zugkettenglieder als Führungselemente für die Rolladenstäbe verwendet werden, was zur Folge hat, daß ein Kettenzug gegenüber dem konventionellen Stand der Technik entfällt. Durch diese Anordnung lassen sich ferner die für die Jalousierbewegung erforderlichen Bauelemente innerhalb der Querschnittsabmessung der Rolladenstäbe unterbringen.According to the invention, the pull chain links and the adjustment chain links are arranged laterally at the two ends of each roller shutter slat, side by side and in alignment with one another, so that the chain links practically represent a lateral extension of the roller shutter slats. As a result, the roller shutter slats on the front and rear surfaces do not build up by the thickness or strength of the chain links, which has a favorable effect on the winding diameter of the Venetian blind. If the pull chain links and adjustable chain links are adapted in their cross-sectional dimensions to the cross-sectional dimensions of the roller shutter slat and thus run essentially flush with the front and rear surfaces of the roller shutter slats, the winding diameter is practically the same as that of a normal roller shutter without a blind device. As a result of the lateral arrangement of the chain links in alignment with the roller shutter bars, there is no overlap of the roller shutter bars by the chain links, which allows the clear width of the blinds opening area to be maximized. This optimization is particularly important if at least the adjustment chain links are designed to be narrow in the manner of lamellae. Furthermore, the pull chain links can be used as guide elements for the roller shutter slats, with the result that a chain pull is opposite the conventional state of the art is eliminated. This arrangement also allows the components required for the blind movement to be accommodated within the cross-sectional dimension of the roller shutter slats.

Im geschlossenen Zustand des Rolladens erreicht man bei Anpassung der Kettenglieder an die Form eines Rolladenstabs ein voll glatt und bündiges Aussehen des Rolladenpanzers.In the closed state of the roller shutter, when the chain links are adapted to the shape of a roller shutter slat, the roller shutter curtain is completely smooth and flush.

Aufgrund der Anordnung der für das Jalousieren erforderlichen Elemente in Flucht des Rolladenstabs verhält sich der jalousierbare Rolladen beim Aufwickeln so, als wäre die Jalousiereinrichtung überhaupt nicht vorhanden. Dadurch lassen sich auch Fehlfunktionen, also ein unbeabsichtigtes Jalousieren, ausschließen.Due to the arrangement of the elements required for the blinds in alignment with the roller shutter rod, the roller shutter that can be rolled up behaves as if the blinding device were not present at all. This also prevents malfunctions, i.e. unintentional blinds.

Wesentlich ist ferner die nach der Erfindung erreichte Entkopplung zwischen den Gelenkkettengliedern einerseits und den Gelenken, die für die schwenkbare Lagerung eines jeden Rolladenstabs an den zugehörigen Zug- und Verstellkettengliedern erforderlich sind. Dadurch lassen sich die Kettengelenke einfach gestalten, ebenso wie die Gelenke zur Aufnahme der Rolladenstäbe. Für die Ketten können einfache Gelenkbolzen verwendet werden, die im oberen Bereich das gesamte Gewicht des darunterhängenden Rolladens zu tragen haben. Hingegen müssen die Gelenkbolzen für die Lagerung der Rolladenstäbe lediglich das Gewicht des einzelnen Rolladenstabs aufnehmen. Dadurch wird auch die Jalousierbewegung erleichtert. Ferner wird eine saubere Trennung zwischen den Kettengelenken und den Jalousiergelenken erreicht, was wiederum ein unbeabsichtigtes Auslösen der Jalousierbewegung verhindert. Im besonderen lassen sich die Gelenkstellen für die Anlenkung des Rolladenstabs an die Kettenglieder aus der vertikalen Ebene der Kettengelenkbolzen verlagern, wodurch sich die Jalousierbewegung begünstigende Hebelarme ergeben. Insgesamt vereinfacht sich die Gestaltung der für die Jalousierung erforderlichen Bauelemente, was sich günstig für die Herstellung des jalousierbaren Rolladens auswirkt.Also essential is the decoupling achieved according to the invention between the articulated chain links on the one hand and the joints, which are required for the pivotable mounting of each roller shutter bar on the associated tension and adjustment chain links. This makes it easy to design the chain links as well as the links to hold the roller shutter slats. Simple hinge pins can be used for the chains, which have to bear the entire weight of the roller shutter hanging underneath in the upper area. On the other hand, the hinge pins for the storage of the roller shutter slats only have to take up the weight of the individual roller shutter slats. This also makes the blind movement easier. Furthermore, a clean separation between the chain joints and the blind joints is achieved, which in turn prevents the blind movement from being triggered unintentionally. In particular, the articulation points for the articulation of the roller shutter rod to the chain links can be displaced from the vertical plane of the chain articulation pins, which results in lever arms which favor the blind movement. Overall, the design of the components required for the blinds is simplified, which is advantageous for the manufacture of the blinds Roller shutter affects.

In diesem Zusammenhang ist es zweckmäßig, die Gelenkbolzen in randseitig der Rolladenstäbe angeordnete einsteckbare Profile zu verlagern, so daß die Rolladenstäbe ohne Rücksicht auf die Jalousierbewegung gestaltet und hergestellt werden können.In this context, it is expedient to shift the hinge pins into insertable profiles arranged on the edge of the roller shutter slats, so that the roller shutter slats can be designed and manufactured regardless of the shutter movement.

Bei Ausbildung der oberen Längsränder der Rolladenstäbe als Feder, d.h. als vorspringende Nase, und der unteren Längsränder als Nut, die komplementär zu den Federn ausgebildet ist, lassen sich die Rolladenstäbe in eine Nut- und Feder-Position verfahren, wodurch sich eine Einbruchssicherung ergibt. Diese Bewegung in die Nut- und Feder-Position und aus dieser heraus kann an den Zug- und Verstellkettengliedern durch entsprechende längsverschiebliche Führung der Kettengelenkbolzen in baulich einfacher Weise aufgefangen bzw. kompensiert werden.If the upper longitudinal edges of the roller shutter slats are designed as springs, i.e. as a projecting nose and the lower longitudinal edges as a groove, which is complementary to the springs, the roller shutter slats can be moved into a tongue and groove position, which results in burglar protection. This movement into and out of the tongue and groove position can be absorbed or compensated for in a structurally simple manner on the pulling and adjusting chain links by corresponding longitudinally displaceable guidance of the chain link pins.

In vorteilhafter Weise sind die Zugkettenglieder mehrteilig, insbesondere zweiteilig, ausgebildet, was fertigungstechnisch Vorteile bringt und die Eingliederung einer verstärkenden Einlage aus Stahl ermöglicht. Die Zugkettenglieder können hierbei aus Materialersparnisgründen hohl ausgebildet sein, wobei der Hohlraum ggf. ausgeschäumt werden kann.The pull chain links are advantageously formed in several parts, in particular in two parts, which brings advantages in terms of production technology and enables the incorporation of a reinforcing insert made of steel. The pull chain links can be hollow for reasons of material savings, the cavity can be foamed if necessary.

Die Auslösung der Jalousierbewegung kann durch unterschiedliche Mechanismen erfolgen, zweckmäßigerweise ist jedoch an einem Verstellkettenglied oder Rolladenstab oder daran angeordnetem Einsteckprofil ein Haken ausgebildet, der mit einem Gegenhaken zur Auslösung der Jalousierbewegung zusammenwirkt. Zweckmäßigerweise ist der Gegenhaken auslenkbar angeordnet, so daß für die normale Rolladenfunktion der Haken am Gegenhaken vorbeigeführt werden kann.The shutter movement can be triggered by different mechanisms, but a hook is expediently formed on an adjustment chain link or roller shutter rod or an insertion profile arranged thereon, which cooperates with a counter-hook to trigger the shutter movement. The counter hook is expediently arranged such that it can be deflected so that the hook can be guided past the counter hook for the normal roller shutter function.

Bei der Ausführungsform nach den Fig. 1 bis 4 ist jedem Rolladenstab 1 ein Zugkettenglied 2 zugeordnet, die untereinander zu einer Zugkette 3 verbunden sind. Die Führung des Rolladens bzw. der Rolladenstäbe erfolgt in üblichen U-förmigen Profilen 4, die an den Wänden des Bauwerks im Bereich der durch den Rolladen zu verschließenden Öffnung befestigt sind. Zur jalousieartigen Verstellung der Rolladenstäbe 1 sind Verstellkettenglieder 5 vorgesehen, von denen jeweils ein Glied einem Ende eines Rolladenstabs 1 analog den Zugkettengliedern zugeordnet ist. Die Verstellkettenglieder 5 sind untereinander zur Bildung einer gelenkigen Verstellkette 6 verbunden.In the embodiment according to FIGS. 1 to 4, each roller shutter slat 1 is assigned a pull chain link 2, which are connected to one another to form a pull chain 3. The roller shutter or roller shutter slats are guided in conventional U-shaped profiles 4, which are fastened to the walls of the building in the region of the opening to be closed by the roller shutters. For the blind-like adjustment of the roller shutter slats 1, adjustment chain links 5 are provided, one link each one end of a roller shutter bar 1 is assigned analogously to the pull chain links. The adjustment chain links 5 are interconnected to form an articulated adjustment chain 6.

Es liegt auf der Hand, daß die Zugkettenglieder 2 und auch die Verstellkettenglieder 5 im jeweiligen Kettenzug vertikal übereinander angeordnet sind. Die an den beiden Enden eines jeden Rolladenstabs 1 vorgesehenen Zugkettenglieder 2 und Verstellkettenglieder 5 sind entsprechend Fig. 2 nebeneinander und, wie aus Fig. 1 hervorgeht, in Flucht zum entsprechenden Rolladenstab 1 angeordnet. Dies hat den Vorteil, daß die Zug- und Verstellkettenglieder 2 und 5 in ihrer Stärke bzw. Dicke nicht auf den Rolladenstab 1 auftragen, so daß bei dieser Anordnung auf die beim Stand der Technik häufig verwirklichte Maßnahme der Platzeinsparung durch Ausbildung von Ausnehmungen an der Vorder- und Rückfläche der Rolladenstäbe 1 verzichtet werden kann, die im übrigen mit einer Schwächung des Rolladenstabs verbunden sind. Ein weiterer Vorteil dieser Anordnung besteht darin, daß beim Aufwickeln des Rolladens der Wickeldurchmesser nur durch die Dicke der Rolladenstäbe 1 bestimmt ist, d.h. die Eingliederung einer Jalousiereinrichtung am Wickelumfang selbst nichts ändert.It is obvious that the pull chain links 2 and also the adjustment chain links 5 are arranged vertically one above the other in the respective chain hoist. The pull chain links 2 and adjustment chain links 5 provided at the two ends of each roller shutter bar 1 are arranged next to one another in accordance with FIG. 2 and, as can be seen from FIG. 1, in alignment with the corresponding roller shutter bar 1. This has the advantage that the tension and adjustment chain links 2 and 5 do not apply in their strength or thickness to the roller shutter rod 1, so that with this arrangement the measure of space saving often implemented in the prior art by forming recesses in the front - And rear surface of the roller shutter slats 1 can be dispensed with, which are otherwise connected to a weakening of the roller shutter slat. Another advantage of this arrangement is that when the roller shutter is wound up, the winding diameter is determined only by the thickness of the roller shutter bars 1, i.e. the inclusion of a blind device on the winding circumference itself does not change anything.

Die Zugkettenglieder 2 sind untereinander gelenkig verbunden. Im dargestellten Ausführungsbeispiel weist jedes Zugkettenglied 2 an seinem unteren Ende eine Gabel 7 gebildet aus zwei zwischen sich eine Ausnehmung begrenzenden Schenkeln und am oberen Ende ein Gelenkauge 8 auf, welches zwischen die Gabelausnehmung greift. Beim Ineinandergreifen von Gabel 7 und Auge 8 ergibt sich somit unter Einschluß eines Gelenkbolzens 9 ein scharnierartiges Gelenk zwischen den Zugkettengliedern 2.The pull chain links 2 are articulated to one another. In the exemplary embodiment shown, each pull chain link 2 has at its lower end a fork 7 formed from two legs delimiting a recess between them and at the upper end an articulated eye 8 which engages between the fork recess. When the fork 7 and the eye 8 interlock, a hinge-like joint is obtained between the pull chain links 2, including an articulated bolt 9.

In analoger Weise erfolgt auch die gelenkartige Verbindung der Verstellkettenglieder 5, wobei die Gabel mit 10, das Gelenkauge mit 11 und der Gelenkbolzen mit 12 bezeichnet sind.The joint-like connection of the adjustment chain links 5 also takes place in an analogous manner, the fork being designated by 10, the joint eye by 11 and the joint bolt by 12.

Entsprechend den Fig. 1, 3 und 4 weisen die Gelenkaugen 8, 11 der Zug- und Verstellkettenglieder 2, 5 ein Langloch 13 auf, in welchem jeweils der Gelenkbolzen 9 bzw. 12 relativ längsverschieblich geführt ist. Die Langlöcher 13 haben den Zweck, das Einfahren der Rolladenstäbe 1 in eine Nut- und Feder-Position und das Herausfahren aus dieser Position zu ermöglichen, wie sich am besten anhand von Fig. 4 ergibt und im übrigen im folgenden noch näher erläutert wird.1, 3 and 4, the hinge eyes 8, 11 of the tension and adjustment chain links 2, 5 have an elongated hole 13, in each of which the hinge pin 9 and 12 is guided relatively longitudinally. The elongated holes 13 have the purpose of making it possible to retract the roller shutter slats 1 into a tongue and groove position and to move them out of this position, as can best be seen in FIG. 4 and will be explained in more detail below.

Jeder Rolladenstab 1 ist an seinen beiden Enden gelenkig mit einem Zug- und Verstellkettenglied 2 und 5 verbunden, um eine Jalousierbewegung des Rolladenstabs 1 zu ermöglichen. Entsprechend Fig. 2 ist jeder Rolladenstab 1 über einen Gelenkbolzen 14 mit einem zugeordneten Zugkettenglied 2 und mittels eines Gelenkbolzens 15 mit einem zugehörigen Verstellkettenglied 5 verbunden. Da der Gelenkbolzen 14 infolge der fluchtenden Anordnung von Zugkettenglied, Verstellkettenglied und Rolladenstab am Verstellkettenglied 5 vorbeigeführt werden muß, ist das Verstellkettenglied 5 an seiner Rückfläche mit einer entsprechenden Ausnehmung 16 versehen. Der Gelenkbolzen 14 ist hierbei im oberen Bereich des Zugkettenglieds 2, hingegen der Gelenkbolzen 5 im unteren Bereich des Verstellkettenglieds 5 verlagert. Die Gelenkbolzen 14 und 15 eines Rolladenstabes 1 sind zueinander bezüglich der vertikalen Ebene versetzt und zwar vorzugsweise im Bereich von 4 bis 5 mm, wie durch die beiden Pfeile in Fig. 1 bei 17 gekennzeichnet ist. Diese Versetzung der beiden Gelenkpunkte zueinander begünstigt die Einleitung und Ausführung der Jalousierbewegung der Rolladenstäbe 1. Die Verlagerung der Gelenkbolzen 14 und 15 in den Rolladenstäben 1 erfolgt im Ausführungsbeispiel nach den Fig. 1 bis 4 in buchsenartigen Profilabschnitten 18, wie sich aus Fig. 1 unten ergibt. Diese Profilabschnitte 18 sind Bestandteile des Profils entweder des Rolladenstabs 1 oder eines an den Enden des Rolladenstabs 1 einsteckbaren bzw. aufsetzbaren Einsteckprofils. Bei der Montage der Zugkettenglieder, Verstellkettenglieder und Rolladenstäbe werden diese Teile somit lediglich seitlich zusammengesteckt, so daß die Gelenkbolzen 14 und 15 in die entsprechenden buchsenartigen Profilabschnitte 18 greifen, insbesondere einschnappen.Each roller shutter slat 1 is articulated at its two ends to a pulling and adjusting chain link 2 and 5, in order to enable the roller shutter slat 1 to move in a louvered manner. According to FIG. 2, each roller shutter slat 1 is connected via a hinge pin 14 to an associated pull chain link 2 and by means of a hinge pin 15 to an associated adjustment chain link 5. Since the hinge pin 14 must be guided past the adjusting chain link 5 due to the aligned arrangement of the pull chain link, adjusting chain link and roller shutter bar, the adjusting chain link 5 is provided on its rear surface with a corresponding recess 16. The hinge pin 14 is here in the upper area of the pull chain link 2, whereas the hinge pin 5 in the lower area of the adjustment chain link 5. The hinge pins 14 and 15 of a roller shutter rod 1 are offset with respect to one another with respect to the vertical plane, and preferably in the range from 4 to 5 mm, as indicated by the two arrows in FIG. 1 at 17. This offset of the two hinge points to each other favors the initiation and execution of the shutter movement of the roller shutter slats 1. The displacement of the hinge pins 14 and 15 in the roller shutter slats 1 takes place in the embodiment according to FIGS. 1 to 4 in socket-like profile sections 18, as can be seen in FIG. 1 below results. These profile sections 18 are components of the profile of either the roller shutter rod 1 or of an insertable or attachable profile at the ends of the roller shutter rod 1. When assembling the pull chain links, adjustable chain links and roller shutter slats, these parts are only put together laterally, so that the hinge pins 14 and 15 engage, in particular snap, into the corresponding bush-like profile sections 18.

Die Betriebsweise des jalousierbaren Rolladens nach den Fig. 1 bis 4 wird am besten anhand der Fig. 3 und 4 erläutert, in denen Fig. 4 die normale Rolladenstellung zeigt, in der die Öffnung durch die Rolladenstäbe verschlossen ist, und Fig. 3 die Jalousierstellung zeigt, in der die Rolladenstäbe aus der vertikalen Ebene in eine mehr oder weniger starke Schräglage herausgeschwenkt sind, so daß zwischen den Rolladenstäben Durchsichtmöglichkeit besteht.1 to 4 is best explained with reference to FIGS. 3 and 4, in which FIG. 4 shows the normal roller shutter position, in which the opening is closed by the roller shutter slats, and FIG. 3 the blind position shows, in which the roller shutter slats are pivoted out of the vertical plane into a more or less strong inclined position, so that there is a possibility of inspection between the roller shutter slats.

Zum Schließen des Rolladens wird der Rolladen in üblicher Weise abgewickelt, wobei die Zugkettenglieder 2 in den seitlichen U-Profilen 4 geführt sind. Die Verschlußstellung erreicht man, sobald der unterste Rolladenstab unten anschlägt und die weiteren Stäbe sich nacheinander aufsetzen, wobei im dargestellten Ausführungsbeispiel ein am Boden der durch den Rolladen zu schließenden Öffnung stationär angeordnetes leistenartiges Teil 19 mit einem nasenförmigen Vorsprung 20 in eine Nut 21 am unteren Längsrand des Rolladenstabs 1 greift bzw. der Rolladenstab auf den Vorsprung 20 aufgefahren wird. Da jeder Rolladenstab 1 an seinem oberen Ende mit einem nasenförmigen Vorsprung 20 und an seinem unteren Ende mit einer komplementär geformten Ausnehmung 21 ausgebildet ist (siehe auch Fig. 1), können die Rolladenstäbe 1 in die in Fig. 4 dargestellte Nut- und Feder-Position gefahren werden, in welcher die Rolladenstäbe 1 übereinander längs einer Vertikalen ausgerichtet sind. In dieser Nut- und Feder-Position ist eine Einbruchsicherung gewährleistet, weil die einzelnen Rolladenstäbe 1 von außen her nicht ausgehoben werden können.To close the roller shutter, the roller shutter is unwound in the usual way, the pull chain links 2 being guided in the lateral U-profiles 4. The closed position is reached as soon as the bottom roller shutter bar hits the bottom and the other bars sit up one after the other, in the illustrated embodiment a strip-like part 19 arranged at the bottom of the opening to be closed by the roller shutter with a nose-shaped projection 20 into a groove 21 at the lower longitudinal edge of the roller shutter rod 1 engages or the roller shutter rod is moved onto the projection 20. Since each roller shutter rod 1 is formed with a nose-shaped projection 20 at its upper end and with a complementarily shaped recess 21 at its lower end (see also FIG. 1), the roller shutter rods 1 can be inserted into the tongue and groove shown in FIG. Position are moved in which the roller shutter slats 1 are aligned one above the other along a vertical. In this tongue and groove position, burglar protection is ensured because the individual roller shutter slats 1 cannot be lifted from the outside.

Soll eine Jalousierung der Rolladenstäbe 1 stattfinden, so müssen die Rolladenstäbe 1 aus ihrer Nut- und Feder-Position ausgefahren werden. Zur Kompensation dieser Bewegung sind die Langlöcher 13 in den Gelenkaugen 8 und 11 der Zug- und Verstellkettenglieder 2 und 5 vorgesehen. Erst in dieser ausgehobenen Stellung lassen sich die Rolladenstäbe jalousieren.If the roller shutter slats 1 are to be blinded, the roller shutter slats 1 must be moved out of their tongue and groove position. To compensate for this movement, the elongated holes 13 are provided in the articulated eyes 8 and 11 of the pull and adjustment chain links 2 and 5. Only in this excavated Position the roller shutter slats can be blinded.

Anzumerken ist hierbei noch, daß bei jalousierbaren Rolladenstäben ganz allgemein die obersten Rolladenstäbe, meist die obersten drei bis fünf Rolladenstäbe, nicht jalousierbar ausgebildet sind, sondern erst die darunter folgenden. Da es sich hierbei aber um einen allgemein bekannten Sachverhalt handelt, ist dies im Vorliegenden nicht eigens erörtert. Jedenfalls weist das Verstellkettenglied des obersten jalousierbaren Rolladenstabs im dargestellten Ausführungsbeispiel einen Haken 22 auf, der zum Auslösen der Jalousierbewegung dient. Mit diesem Haken 22 wirkt ein Gegenhaken 23 zusammen, der an einem Lenkhebel 24 sitzt, der bei 25 gelenkig an einem ortsfesten Teil, etwa am U-Profil 4, befestigt ist. Oberhalb des Gegenhakens 23 befindet sich ein Auslenkglied 26 mit einer Schrägfläche 27, wobei im dargestellten Ausführungsbeispiel das Auslenkglied 26 an einem Stab 28 geführt und durch eine Feder 29 in seine untere Lage vorgespannt ist. Beim Herablassen des Rolladenpanzers fährt der Haken 22 am Gegenhaken 23 vorbei, weil der Lenkhebel 24 beim Auftreffen des Hakens 22 auf die Schrägfläche 27 nach außen weggeschwenkt wird. Zum Jalousieren ist der Rolladenpanzer durch Hochziehen des Rolladengurtes aus einer Nut- und Feder-Position zu heben, wobei der Haken 22 am Gegenhaken 23 von unten her kommend vorbeiläuft, was auch hier durch eine Schrägfläche 29 begünstigt ist, die ein Auslenken des Lenkhebels bewerkstelligt. Wird weiter hochgezogen, so drückt der Haken 22 das Auslenkglied 26 entgegen der Federvorspannung nach oben, wobei beim weiteren Hochziehen der Haken 22 schließlich infolge Auslenkung des Lenkhebels 24 ohne weiteres das Auslenkglied 26 passieren kann. Für das Jalousieren wird aber der Haken 22 nur über den Gegenhaken 23 gefahren und dann wieder abgesenkt, wobei dann der Haken 22 unmittelbar mit dem Gegenhaken 23 zusammenwirkt, da der Lenkhebel nicht mehr aufgrund einer Schrägfläche ausgelenkt wird. Beim weiteren Absenken des Rolladens verhakt sich der Haken 22, so daß die Verstellkettenglieder 5 in ihrer vertikalen Lage festgehalten, jedoch die Zugkettenglieder 2 weiter abgesenkt werden, so daß das Jalousieren der Rolladenstäbe 1 eintritt. Soll die Jalousierstellung aufgehoben werden, so wird der Gurt wieder angezogen, so daß die Zugkettenglieder 2 angehoben und schließlich, nachdem die Rolladenstäbe 1 weitgehend in Flucht mit den Zugkettengliedern 2 verschwenkt sind, der Haken 22 aus der Eingriffsstellung gefahren und der Rolladenpanzer nach oben gezogen werden kann. Hierbei sind die zugeordneten Zug-, Verstellkettenglieder und Rolladenstäbe wieder vertikal in Flucht zueinander ausgerichtet, so daß der Rolladenpanzer wie ein normaler Rolladenpanzer aufgewickelt werden kann. Das heißt, die Zugkettenglieder und Verstellkettenglieder sind bündig mit den Rolladenstäben, was durch die Anordnung der Elemente in Flucht zueinander ermöglicht wird. Beim Aufwickeln baut somit der jalousierbare Rolladen nicht stärker auf (kein größerer Wickeldurchmesser) als ein normaler Rolladen ohne Jalousiereinrichtung.It should also be noted here that in the case of roller shutter slats which can be louvered, the uppermost roller shutter slats, generally the uppermost three to five roller shutter slats, are generally not designed to be louvered, but only those below. However, since this is a generally known fact, this is not specifically discussed in the present. In any case, the adjustment chain link of the uppermost roller shutter slat in the illustrated embodiment has a hook 22, which serves to trigger the blind movement. With this hook 22, a counter hook 23 interacts, which sits on a steering lever 24, which is articulated at 25 to a stationary part, for example on the U-profile 4. Above the counter hook 23 there is a deflecting member 26 with an inclined surface 27, the deflecting member 26 being guided on a rod 28 in the exemplary embodiment shown and being biased into its lower position by a spring 29. When the roller shutter curtain is lowered, the hook 22 moves past the counter hook 23 because the steering lever 24 is pivoted outwards when the hook 22 hits the inclined surface 27. For blinding, the roller shutter armor is to be lifted from a tongue and groove position by pulling up the roller shutter belt, the hook 22 running past the counter hook 23 coming from below, which is also favored here by an inclined surface 29 which brings about a deflection of the steering lever. If it is pulled up further, the hook 22 presses the deflection member 26 upward against the spring preload, the hook 22 finally being able to easily pass the deflection member 26 as a result of the deflection of the steering lever 24 when the hook 22 is further raised. For the blinds, however, the hook 22 is only moved over the counter hook 23 and then lowered again, the hook 22 then interacting directly with the counter hook 23, since the steering lever is no longer deflected due to an inclined surface. When the roller shutter is lowered further, the hook 22 hooks, so that the adjusting chain links 5 are held in their vertical position, but the pull chain links 2 are further lowered, so that the blinds of the roller shutter bars 1 occur. If the blind position is to be lifted, the belt is tightened again so that the pull chain links 2 are raised and finally, after the roller shutter bars 1 are largely pivoted in alignment with the pull chain links 2, the hook 22 is moved out of the engaged position and the roller shutter armor is pulled upwards can. Here, the associated tension, adjustment chain links and roller shutter slats are again aligned vertically so that the roller shutter curtain can be wound up like a normal roller shutter curtain. This means that the pull chain links and adjustable chain links are flush with the roller shutter slats, which is made possible by the arrangement of the elements in alignment with one another. When rolling up, the blinds that can be rolled up therefore do not build up more (no larger roll diameter) than a normal blind without a blind.

Bei der Ausführungsform nach den Fig. 5 bis 8 sind für dieselben Bauteile die gleichen Bezugszeichen verwendet worden. Bei dieser gleichfalls weitgehend schematisch nur anhand eines Teils des Rolladens dargestellten Ausführungsform sind die Zugkettenglieder 2 zweiteilig ausgebildet, wobei die Hälften mit 2a und 2b bezeichnet sind. Diese zweiteilige Ausbildung hat fertigungstechnische Vorteile, weil die Zugkettenglieder hohl und aus Kunststoff hergestellt sind und zum Zugkettenglied zusammengesteckt werden können. Hierbei lassen sich weitgehend gleiche Wanddicken erreichen, was fertigungstechnisch vorteilhaft ist. Im besonderen läßt sich infolge dieser Zweiteilung jedoch eine lamellenartige Stahleinlage 2c zwischen den Profilhälften 2a und 2b anordnen, wodurch sich eine Festigungserhöhung ergibt. Eine solche Ausführungsform eignet sich insbesondere für Rolläden mit einer entsprechenden Länge und Breite. Die Versetzung der Teile bei 30 erklärt sich daraus, daß die Zugkettenglieder oben und unten zur Aufnahme des Gelenkbolzens 9 vorbeigeführt werden müssen. Aus der Darstellung rechts in Fig. 5 ergibt sich das Ineinanderfahren der Rolladenstäbe 1 in die Nut- und Feder-Position infolge Ineinandergreifens der nasenartigen Vorsprünge 20 und der Ausnehmungen 21. Das gleichfalls sehr schmale Verstellkettenglied 5 ist oben bei 31 gegabelt, um das untere Ende des darüberliegenden Verstellkettenglieds scharnierartig aufzunehmen.In the embodiment according to FIGS. 5 to 8, the same reference numerals have been used for the same components. In this embodiment, which is also shown largely schematically using only part of the roller shutter, the pull chain links 2 are formed in two parts, the halves being designated by 2a and 2b. This two-part training has advantages in terms of production technology because the pull chain links are hollow and made of plastic and can be plugged together to form the pull chain link. In this way, largely the same wall thicknesses can be achieved, which is advantageous in terms of production technology. In particular, as a result of this division in two, a lamellar steel insert 2c can be arranged between the profile halves 2a and 2b, which results in an increase in strengthening. Such an embodiment is particularly suitable for roller shutters with a corresponding length and width. The displacement of the parts at 30 can be explained by the fact that the pull chain links must be passed above and below to receive the hinge pin 9. From the illustration on the right in FIG. 5, the rolling shutters 1 move into one another in the tongue and groove position due to the interlocking of the nose-like projections 20 and the recesses 21. The likewise very narrow adjustment chain link 5 is bifurcated at 31 to receive the lower end of the overlying adjustment chain link in a hinge-like manner.

Bei 32 ist eine am Teil 2b seitlich angeformte Zunge zu erkennen, die auch in Fig. 4 ersichtlich ist und die das Verstellkettenglied 5 von hinten überdeckt und damit in Schließstellung des Rolladenpanzers eine Durchsicht zwischen Zugkettenglied und zugeordnetem Rolladenstab 1 verhindert.At 32, a tongue formed laterally on part 2b can be seen, which can also be seen in FIG. 4 and which covers the adjustment chain link 5 from behind and thus prevents a view between the pull chain link and the assigned roller shutter rod 1 in the closed position of the roller shutter curtain.

Der aus Fig. 6 ersichtliche Gelenkbolzen 14 für die gelenkige Aufhängung des Rolladenstabs 1 dient zugleich als Befestigung der beiden Hälften 2a und 2b des Zugkettenglieds 2. Beim Ausführungsbeispiel nach Fig. 6 sind sowohl der Gelenkbolzen 14 wie auch der Gelenkbolzen 15 in einem Einsteckprofil 33 des Rolladenstabs 1 verlagert, der seitlich in das offene Ende des Rolladenstabes 1 einsteckbar ist. Dadurch kann der Rolladenstab 1 als im Querschnitt über die gesamte Länge gleichbleibend konturiertes Bauteil in entsprechenden Längen hergestellt und in der Fertigung auf die gewünschte Rolladenstablänge zugeschnitten werden.The hinge pin 14 shown in FIG. 6 for the articulated suspension of the roller shutter bar 1 also serves as fastening of the two halves 2a and 2b of the pull chain link 2. In the embodiment according to FIG. 6, both the hinge pin 14 and the hinge pin 15 are in an insertion profile 33 of the Roller shutter rod 1 is shifted, which can be inserted laterally into the open end of the roller shutter rod 1. As a result, the roller shutter rod 1 can be produced as a component of corresponding lengths that is contoured over the entire length and can be cut to the desired length of the roller shutter rod during production.

Fig. 7 zeigt die Rolladenstäbe 1 in normaler Schließstellung und Fig. 8 den Rolladen in jalousierter Stellung der Stäbe 1, wobei mit 1' der bereits zuvor erläuterte festbleibende Rolladenstab bezeichnet ist. In Fig. 8 ist unten schematisch das ortsfeste Führungsprofil 4 zum Führen der Rolladenstäbe 1 bzw. der Zugkettenglieder 2 dargestellt.FIG. 7 shows the roller shutter slats 1 in the normal closed position and FIG. 8 the roller shutter in the blinded position of the slats 1, 1 ′ denoting the fixed roller shutter slat which has already been explained above. In Fig. 8, the stationary guide profile 4 for guiding the roller shutter bars 1 or the pull chain links 2 is shown schematically below.

Aus Fig. 8 ist auch eine Ausführungsvariante des Hakens ersichtlich. Der Haken 22 ist hierbei am Verstellkettenglied des obersten jalousierbaren Rolladenstabs 1 federnd angelenkt, so daß der Haken 22 beim Aufwickeln der Rolladenstäbe 1 nach innen geschwenkt werden kann und somit beim Aufwickeln der Rolladenstäbe 1 nicht mehr stört. Sobald beim Abwickeln der Rolladenstäbe 1 der Haken 22 freigegeben wird, schwenkt er in die in Fig. 8 ersichtliche Position, wo er mit einem ortsfest angeordneten Gegenhaken 23 zum Auslösen der Jalousierbewegung zusammenwirkt. Aus Fig. 8 unten sind hakenartige Endausbildungen der Gelenkbolzen 14 und 15 ersichtlich, die beim Zusammenstecken hinter entsprechende Rastausbildungen am Rolladenstab 1 oder Einsteckprofil 33 greifen, so daß die Gelenkbolzen 14 und 15 fest verrastet werden können. Zur Montage brauchen die Zugkettenglieder, die Verstellkettenglieder und die Rolladenstäbe 1 nur durch Zusammenstecken über die Gelenkbolzen zusammengesteckt werden. Ersichtlich ist die Anlenkung der Rolladenstäbe 1 an den Verstellkettengliedern und den Zugkettengliedern völlig unabhängig und damit entkoppelt von der Verbindung der Zugkettenglieder und Verstellkettenglieder zu einer Kette untereinander, so daß die Gelenkbolzen 14 und 15 festigkeitsmäßig nur zur Aufnahme des Gewichts eines Rolladenstabes dimensioniert werden müssen.An embodiment variant of the hook can also be seen from FIG. The hook 22 is resiliently articulated on the adjustment chain link of the uppermost roller shutter slat 1, so that the hook 22 can be pivoted inwards when winding up the roller shutter slats 1 and thus no longer interferes with the winding up of the roller shutter slats 1. As soon as unwinding of the roller shutter slats 1, the hook 22 is released, it pivots into the position shown in FIG. 8, where it interacts with a fixedly arranged counter hook 23 for triggering the blind movement. From Fig. 8 below hook-like end configurations of the hinge pins 14 and 15 can be seen, which when plugging together engage behind corresponding latching configurations on the roller shutter rod 1 or insert profile 33, so that the hinge pins 14 and 15 can be firmly locked. For assembly, the pull chain links, the adjustment chain links and the roller shutter bars 1 need only be put together by plugging them together via the hinge pins. As can be seen, the articulation of the roller shutter slats 1 on the adjustment chain links and the pull chain links is completely independent and thus decoupled from the connection of the pull chain links and adjustment chain links to form a chain with one another, so that the hinge pins 14 and 15 have to be dimensioned in terms of strength only to accommodate the weight of a roller shutter bar.

Claims (15)

  1. Rolling shutter with tilting slats, having a number of tiltable lamellar rolling-shutter bars (1) which are connected in articulated fashion at their upper ends to pulling chain links (2) and at their lower ends to adjusting chain links (5) and are guided at the sides in fixed guide profiles (4) via chain links, characterised in that guidance in the guide profiles (4) is provided by the pulling chain links (2), which, in each case with the associated adjusting chain links (5) and tiltable rolling-shutter bars (1), are arranged directly next to one another, those surfaces of the pulling chain links, adjusting chain links and rolling-shutter bars which face the outside of the rolling shutter being in alignment with one another in the closure position and the adjusting chain links (5) being arranged outside the guide profiles (4).
  2. Rolling shutter according to Claim 1, characterised in that the pulling chain links (2) are connected by means of a hinge joint (7, 8, 9) to form a pulling chain (3), in that the adjusting chain links (5) are connected to one another by means of a hinge joint (10, 11, 13) to form an adjusting chain (6) and in that the rolling-shutter bars (1) are articulated on the corresponding adjusting chain links (5) and pulling chain links (2) by means of separate hinge pins (14, 15) and are decoupled from the hinge joints (7, 8, 9; 10, 11, 12).
  3. Rolling shutter according to Claim 1 or 2, characterised in that each tiltable rolling-shutter bar (1) is connected at its end to in each case one pulling chain link (2) and one adjusting chain link (5) by an upper and a lower hinge pin (14, 15), which are arranged spatially between the hinge joints (7, 8, 9; 10, 11, 12) of the pulling and adjusting chain links (2, 5).
  4. Rolling shutter according to one of Claims 1 to 3, characterised in that, to hang the rolling-shutter bars (1), the hinge pins (14, 15) are offset relative to one another out of the vertical plane (shown at 17), preferably uniformly within a range of from 4 to 5 mm.
  5. Rolling shutter according to one of the preceding claims, characterised in that the upper hinge pin (14) is connected to the pulling chain link (2) and the lower hinge pin (15) to the adjusting chain link (5) arranged between the pulling chain link (2) and the rolling-shutter bar (1).
