Definitions

  • the present invention relates to a venetian blind according to claim 6 of the present invention.
  • Another aspect of the invention relates to a slat according to claim 1 for use in a slat blind.
  • Slat blinds are used to protect against sun rays and the weather.
  • the slat blinds can in particular be attached to the outside of a building in front of windows and / or doors.
  • Slat blinds are known which contain a blind curtain with a plurality of slats and a lower rail that closes off the blind curtain at the bottom.
  • the slats and the closing bottom rail can be guided laterally between the respective guide rails.
  • the slats can be joined together with the closing bottom rail by flexible connecting elements, e.g. Cords to be connected together.
  • the individual slats can be swiveled into different inclinations in order to regulate the incidence of light.
  • a ruffled slat blind the slats of which have a curved and slightly Z-angled cross-sectional shape.
  • a slat of a blind or external venetian blind with a front and rear edge and side edges connecting these. At least one side edge has two sub-sections offset from one another to form a step, with a preferably slot-shaped recess being provided in one sub-section of the side edge.
  • One problem in the prior art is that a gap is created between the side ends of the respective slats and the respectively assigned guide rails through which light can enter the building.
  • Another disadvantage is that, additionally or alternatively, light enters the interior of the building via respective through-holes in the slats, through which elevator belts are guided, which run from the upper receptacle to the lower rail. Said disadvantageous incidence of light via the gaps and / or the perforations in the slats has the disadvantage that complete darkening is not achieved.
  • roller shutters which comprise a curtain made of visor elements that are flexibly connected to one another, the curtain being rolled up or unrolled for opening and closing. The entire hanging is laterally guided vertically within guide rails.
  • a roller shutter is not completely closed, the panel elements that are adjacent to one another in the vertical direction are held at a distance from one another by corresponding flexible straps. In this way, incidence of light through gaps between the respectively adjacent panel elements can be ensured. Only when the roller shutter is completely closed do all the panel elements lie essentially flush with one another, so that in this state one can speak of essentially complete darkening.
  • a disadvantage of this solution is that the incidence of light can only be adjusted within a narrow range.
  • Another disadvantage is that the user can only look outside to a very limited extent through the gaps in the adjacent panel elements. So that the user can have a complete look outside, the curtain of the roller shutter would have to be rolled up every time, which is laborious and time-consuming and leads to high wear.
  • a further disadvantage is a so-called roller shutter box, within which the curtain is rolled up, very large in size and takes up a lot of space. In addition, the roller shutter box takes up a large area of this in the upper section of a window or a door, which disadvantageously reduces the amount of light entering the building.
  • the object of the present invention is to provide a slat and a slatted blind which does not have the disadvantages mentioned above.
  • a slat according to claim 1 and a slat blind comprising: laterally arranged guide rails, a blind curtain with a plurality of slats arranged between the guide rails, a lower rail closing the blind curtain, and at least one elevator device.
  • the slats each have a closing panel surface and an upper edge angled for this purpose in the upper section, the angled upper edge being provided with laterally protruding guide pins over which the slats are pivotably guided in the guide rails.
  • the concluding panel surface protrudes laterally over the angled upper edge in such a way that protruding sections of the panel surface can be brought into contact with the guide rails when the blind is closed and are overlapped with the guide rails, so that this overlap does not result in direct light between the slats and the lateral ones Guide rails collapses.
  • the slat blind according to the present invention allows almost complete darkening, since the individual slats in the closed state with their faceplate surfaces are laterally brought into contact with the two guide rails.
  • the end faces of the Slats with the guide rails so that, compared to the prior art, in which the bottom rail For example, it is mounted in the middle, or the fulcrum of the slats is on their faceplate, no gap is created through which direct light can enter the building interior.
  • This advantage is achieved in that the guide pins are each attached to a section of the lamellas, here defined as the upper edge, which is angled with respect to the faceplate.
  • the individual slats swing down by gravity and are supported by the outer surfaces of the guide rails, or the faceplate surfaces of the individual slats come into contact with their rear side.
  • the upper edge can be angled at an angle in a range from 50 ° to 90 °, preferably substantially 70 °, with respect to the screen surface.
  • the lower rail is kept in a horizontal position in order to keep the slat stack in a horizontal position.
  • the lower rail can also be pivoted. However, this is not absolutely necessary.
  • the lower rail can also be non-pivotable.
  • the slat blind according to the invention allows a degree of darkening in the closed state, which can be similar to that of a roller shutter - but with a very significant advantage over a roller shutter, namely that the slats can simply be tilted at any time so that light can enter the interior of the building The user is able to look outside almost undisturbed.
  • the light / brightness regulation of the slat blinds according to the invention is greatly improved compared to roller shutters. This is the first time that an extremely reliable slat blind has been created, which offers almost complete darkening with simple means and also very comprehensive light / brightness regulation.
  • the slatted blind according to the invention also advantageously allows complete privacy protection from the outside into the interior of the building.
  • the slatted blind according to the invention also has a burglar-resistant appearance because when closed it looks like a roller shutter from the outside.
  • vertically adjoining lamellae are overlapped at least in sections.
  • lower edge sections of the diaphragm surfaces each rest on the upper edge portions of the diaphragm surface of lamellas arranged below.
  • the elevator device preferably contains at least one belt drive or a belt elevator.
  • the belt drive is arranged in the area of the guide rails. Examples of a belt drive are a toothed belt drive, a perforated belt drive, etc.
  • the belt elevator can be provided, which raises or lowers the lower rail via elevator belts.
  • the tape elevator can be arranged in any section between the two guide rails.
  • the elevator device preferably contains at least one electrically and / or manually drivable drive device.
  • Exemplary actuators for manually driving the elevator device can include a crank or an elevator cord.
  • An electrically drivable drive device can have an electric motor which raises or lowers the blind curtain by motor power. The inclination of the slats can also be changed by an electric drive.
  • the belt drive contains at least one toothed wheel, which is coupled to the drive device, and at least one belt, the belt being coupled at the lower end to the lower rail and at the further end is at least partially in engagement with teeth of the gear.
  • the belt can be a perforated belt, a toothed belt, etc.
  • the belt drive is characterized by the fact that it can absorb high forces.
  • the belts are preferably each guided within the guide rails.
  • the straps can be made of an elastic plastic material.
  • an elastic strap e.g. the perforated belt, guided 180 ° around the gear and thus comes into reliable contact with it.
  • the belt can be made from an abrasion-resistant plastic material.
  • the tape elevator contains an elevator tape which is coupled at one end to the lower rail and at least in sections can be wound or unwound at the other end by the at least one tape elevator.
  • the lower rail is reliably lifted and lowered by the belt lifts and the respectively assigned lift belts.
  • the slatted blind preferably also contains at least one cable elevator for winding or unwinding a cable coupled to the lower rail.
  • This embodiment is used for a venetian blind, in which the elevator device contains the at least one belt drive.
  • the lower rail is supported against bending by means of the cable lift.
  • the cable drive can be arranged centrally between the guide rails.
  • the at least one cable drive preferably contains a rotatable roller which is coupled to the drive device, the cable being coupled to the lower rail at one end and being able to be wound at least in sections on the circumference of the roller at the other end.
  • the roller can be rotated by an applied torque from an electric motor coupled to it.
  • the angled upper edges of the slats are preferably each provided with at least one through-hole, and the rope or the elevator belt is guided through these through-holes in the course between the cable drive and the lower rail or between the belt elevator and the lower rail.
  • a very significant advantage of this embodiment is that the elevator tape or the rope in the closed state of the blinds, with the slats inclined into the darkening position, runs completely behind the face of the blinds when viewed from the outside. The elevator tape or the rope is therefore not exposed to any UV radiation in the closed state (ie in the shaded state) of the blind curtain.
  • the elevator tape or the rope is and are effectively protected against UV radiation Aging processes of the elevator tape or of the rope are advantageously greatly delayed, whereby the wear thereof is greatly reduced. This significantly extends the service life of the elevator tape or rope.
  • Another advantage is that, in the completely closed state of the blind curtain, the through-holes for passing the elevator tape or the rope are not exposed to the outside. As a result, no light can enter the interior of the building through these perforations. Likewise, no unauthorized look inside the building can be thrown from the outside. Thus, a slat blind is created which enables complete darkening and complete privacy protection.
  • the cable drive is preferably arranged in a section of the slatted blind which is offset from the guide rails. In this way, in the case of especially long lower rails, it can be avoided that these are bent in the middle.
  • the cable drive offset from the guide rails is preferably set up to raise or lower the lower rail at a speed at which the belt drives installed in the guide rails raise or lower the lower rail. This advantageously ensures synchronicity between the drives and it can be avoided that the bottom rail along its entire length with is raised or lowered at different speeds and may be bent as a result.
  • the cable drive offset from the guide rails is preferably set up to wind up the cable, lined up in one layer, on the circumference of the roller along a longitudinal direction thereof.
  • This avoids the rope winding up on top of each other, which would have the disadvantage that the constantly increasing diameter also increases the relative speed at which the lower rail, e.g. in the middle of this, is raised.
  • Relative speed refers to the speed at which the blind curtain is moved on the sides (guide rails).
  • the slat blind preferably further comprises at least one turning device for adjusting the inclination of at least one of the slats.
  • the angle of inclination of the slats is reliably changed, namely in a range between complete darkening (essentially vertical orientation) and an essentially horizontal orientation.
  • the user can quickly and easily regulate the incidence of light and take a look outside.
  • the slatted blind preferably also contains a lever mechanism, set up to translate a substantially linear movement into a tilting movement for adjusting the inclination of the lower rail.
  • the bottom rail is suspended or stored at the end over the angled upper side (eccentrically). Therefore, compared to a solution in which the lower rail is mounted in the middle, for example, a greater force must be applied in order to incline the lower rail in the freely hanging state in the direction of horizontal alignment.
  • the lever mechanism is provided for power transmission.
  • the lever mechanism can be designed, for example, as a toggle lever, which generates an essentially long linear movement into a relatively short tilting movement with an increased force.
  • the lever mechanism can be any mechanism with a high power transmission or torque transmission.
  • the slat blind preferably further comprises a slide for receiving the lever mechanism, the slide being movable at least in sections together with the lower rail along the guide rail.
  • the lever mechanism thus follows the vertical direction, in which the lower rail is moved along the guide rail.
  • the turning device preferably contains a ball cord and a deflection device which is set up to deflect the ball cord in such a way that essentially parallel courses thereof are at a predetermined distance from one another.
  • a deflection device which is set up to deflect the ball cord in such a way that essentially parallel courses thereof are at a predetermined distance from one another.

  • the slat blind 10 contains two guide rails 12 (for reasons of illustration only one guide rail is shown) for vertically guiding a blind curtain 14 arranged between the guide rails 12, which in turn contains a plurality of slats 16'-16 '''.
  • the slat blind 10 is shown in the open state of the blind curtain 14. Although only three slats 16'-16 "'are shown in the drawing, a typical venetian blind 10 contains significantly more slats.
  • the blind curtain 14 is closed below by a lower rail 18.
  • the lower rail 18 is supported in the center via a rope 20 connected to it, so that the lower rail 18 will not sag.
  • the rope 20 is wound or unwound from a cable elevator 22 on the circumference of a roller (not shown).
  • the cable elevator 22 thus prevents the (long) lower rail 18 from sagging or being bent in the middle, in particular in the case of very wide slat blinds 10, as described in more detail below.
  • the lower rail 18 is moved up and down by means of a belt drive 24 which is integrated in the guide rail 12 (described in more detail below).
  • a belt drive 24 which is integrated in the guide rail 12 (described in more detail below).
  • slats positioned one on top of the other are sequentially picked up and with the lower rail 18 and already recorded slats are moved further upwards until this slat also receives a previously higher-level slat, and so on (generally known as the external venetian blind principle).
  • the package of the lamellas and the lower rail 18 itself can assume a high overall weight, which is reliably absorbed by the belt drive 24 on the sides.
  • the belt drive 24 contains a toothed wheel 26 which can be driven to rotate.
  • the gear wheel 26 engages with a belt 28 which is guided within the guide rail 12.
  • the belt 28 is in turn coupled to the lower rail 18 at the lower end. During one revolution of the gear wheel 26, the rotary movement is thus converted into a linear movement of the belt 28 for raising or lowering the lower rail 18.

This avoids the rope 20 being wound up in several layers - along with a steadily increasing diameter - which in turn increases the speed at which the rope 20 is wound up while the speed remains the same.
  • the cable drive 22 allows the cable 20 to be wound up and unwound at a constant speed or at a speed which is always the same (synchronous) with the speed of other elevator devices (e.g. the belt drives set up within the guide rails (see e.g. Figure 1b )).

  • Fig. 10 illustrates an example of the roller 44 which includes a sectionally spiral rope take-up.
  • the roller 44 contains a spiral winding section 52 with a spiral increasing radius. This makes it possible for the rope 20, starting from the closed state of the slatted blinds, to be wound up with a lower rope winding speed during the first turn. A structurally simple and reliable measure thus creates the possibility of minimizing overflow.

Description

Die vorliegende Erfindung betrifft eine Lamellenstore gemäss Anspruch 6 der vorliegenden Erfindung. Ein weiterer Aspekt der Erfindung betrifft eine Lamelle nach Anspruch 1 zur Verwendung in einer Lamellenstore.The present invention relates to a venetian blind according to claim 6 of the present invention. Another aspect of the invention relates to a slat according to claim 1 for use in a slat blind.

Lamellenstoren dienen zum Schutz gegen Sonnenstrahlen und Witterung. Die Lamellenstoren können insbesondere an der Aussenseite eines Gebäudes vor Fenstern und/oder Türen angebracht werden. Es sind Lamellenstoren bekannt, welche einen Storenbehang mit einer Mehrzahl von Lamellen und eine den Storenbehang unten abschliessende Unterschiene enthalten. Die Lamellen und die abschliessende Unterschiene können seitlich zwischen jeweiligen Führungsschienen geführt werden. Die Lamellen können zusammen mit der abschliessenden Unterschiene durch flexible Verbindungselemente, z.B. Kordeln, miteinander verbunden werden. Zusätzlich können die einzelnen Lamellen in verschiedene Neigungsstellungen verschwenkt werden, um hierdurch einen Lichteinfall zu regulieren.Slat blinds are used to protect against sun rays and the weather. The slat blinds can in particular be attached to the outside of a building in front of windows and / or doors. Slat blinds are known which contain a blind curtain with a plurality of slats and a lower rail that closes off the blind curtain at the bottom. The slats and the closing bottom rail can be guided laterally between the respective guide rails. The slats can be joined together with the closing bottom rail by flexible connecting elements, e.g. Cords to be connected together. In addition, the individual slats can be swiveled into different inclinations in order to regulate the incidence of light.

Wenn der Storenbehang in die tiefstmögliche Stellung abgesenkt ist und die einzelnen Lamellen zusammen mit der Unterschiene maximal aus der horizontalen Stellung heraus geschwenkt sind, kann ein Lichteinfall weitestgehend abgeschirmt werden, bzw. ein hoher Verdunkelungsgrad erzielt werden.When the blinds are lowered to the lowest possible position and the individual slats, together with the lower rail, are swiveled out of the horizontal position as much as possible, the incidence of light can be largely shielded or a high degree of darkening can be achieved.

Aus der DE 29613220 U1 bekannt ist eine raffbare Lamellenjalousie, deren Lamellen u.a. eine gekrümmte und schwach Z-winkelige Querschnittsform aufweisen. Aus der DE 20 2005 003 668 U1 bekannt ist eine Lamelle einer Jalousie bzw. Raffstore mit einer Vorder- und Hinterkante sowie diese verbindende Seitenkanten. Zumindest eine Seitenkante weist zwei unter Ausbildung einer Stufe gegeneinander versetzte Teilabschnitte auf, wobei in einem Teilabschnitt der Seitenkante eine vorzugsweise schlitzförmige Ausnehmung vorgesehen ist.From the DE 29613220 U1 Known is a ruffled slat blind, the slats of which have a curved and slightly Z-angled cross-sectional shape. From the DE 20 2005 003 668 U1 Known is a slat of a blind or external venetian blind with a front and rear edge and side edges connecting these. At least one side edge has two sub-sections offset from one another to form a step, with a preferably slot-shaped recess being provided in one sub-section of the side edge.

Ein Problem im Stand der Technik besteht darin, dass sich zwischen den Seitenenden der jeweiligen Lamellen und den jeweils zugeordneten Führungsschienen ein Spalt einstellt, durch welchen Licht ins Gebäudeinnere einfällt. Ein weiterer Nachteil besteht darin, dass, zusätzlich oder alternativ, über jeweilige Durchbohrungen in den Lamellen, durch welche Aufzugsbänder geführt sind, die von der oberen Aufnahme bis zur Unterschiene verlaufen, Licht ins Gebäudeinnere einfällt. Der besagte nachteilige Lichteinfall über die Spalten und/oder die Durchbohrungen in den Lamellen hat den Nachteil, dass keine vollständige Verdunkelung erzielt wird.One problem in the prior art is that a gap is created between the side ends of the respective slats and the respectively assigned guide rails through which light can enter the building. Another disadvantage is that, additionally or alternatively, light enters the interior of the building via respective through-holes in the slats, through which elevator belts are guided, which run from the upper receptacle to the lower rail. Said disadvantageous incidence of light via the gaps and / or the perforations in the slats has the disadvantage that complete darkening is not achieved.

Es sind Rollladen bekannt, welche einen Behang aus miteinander flexibel verbundenen Blendenelementen umfassen, wobei der Behang zum Öffnen und Schliessen jeweils aufgerollt bzw. abgerollt wird. Der gesamte Behang wird seitlich innerhalb von Führungsschienen vertikal geführt. Im nicht vollständig geschlossenen Zustand eines Rollladens werden jeweils die in vertikaler Richtung zueinander benachbarten Blendenelemente durch entsprechende flexible Bänder zueinander beabstandet gehalten. Hierdurch kann ein Lichteinfall durch Spalten zwischen den jeweils benachbarten Blendenelementen gewährleistet werden. Erst beim vollständigen Schliessen des Rollladens liegen alle Blendenelemente im Wesentlichen bündig aufeinander, so dass in diesem Zustand von einer im Wesentlichen vollständigen Verdunkelung gesprochen werden kann. Ein Nachteil bei dieser Lösung besteht darin, dass der Lichteinfall nur innerhalb eines schmalen Grades einstellbar ist. Ferner nachteilhaft kann der Benutzer durch die Spalten der zueinander benachbarten Blendenelemente nur sehr beschränkt einen Blick nach Aussen werfen. Damit der Benutzer einen vollständigen Blick nach Aussen werfen kann, müsste jedes Mal der Behang des Rollladens aufgerollt werden, welches mühsam und zeitaufwendig ist und zu einem hohen Verschleiss führt. Ferner nachteilig ist ein sogenannter Rollladenkasten, innerhalb welchem der Behang aufgerollt wird, sehr grossformatig und nimmt viel Platz ein. Zudem nimmt der Rollladenkasten im oberen Abschnitt eines Fensters oder einer Türe eine grosse Fläche hiervon ein, wodurch nachteilhafterweise verringert Licht in das Gebäudeinnere eintritt.There are known roller shutters which comprise a curtain made of visor elements that are flexibly connected to one another, the curtain being rolled up or unrolled for opening and closing. The entire hanging is laterally guided vertically within guide rails. When a roller shutter is not completely closed, the panel elements that are adjacent to one another in the vertical direction are held at a distance from one another by corresponding flexible straps. In this way, incidence of light through gaps between the respectively adjacent panel elements can be ensured. Only when the roller shutter is completely closed do all the panel elements lie essentially flush with one another, so that in this state one can speak of essentially complete darkening. A disadvantage of this solution is that the incidence of light can only be adjusted within a narrow range. Another disadvantage is that the user can only look outside to a very limited extent through the gaps in the adjacent panel elements. So that the user can have a complete look outside, the curtain of the roller shutter would have to be rolled up every time, which is laborious and time-consuming and leads to high wear. A further disadvantage is a so-called roller shutter box, within which the curtain is rolled up, very large in size and takes up a lot of space. In addition, the roller shutter box takes up a large area of this in the upper section of a window or a door, which disadvantageously reduces the amount of light entering the building.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Lamelle sowie eine Lamellenstore anzugeben, welche die vorstehend genannten Nachteile nicht aufweist.The object of the present invention is to provide a slat and a slatted blind which does not have the disadvantages mentioned above.

Diese Aufgabe wird gelöst durch eine Lamelle gemäss Anspruch 1 sowie eine Lamellenstore, umfassend: seitlich angeordnete Führungsschienen, einen zwischen den Führungsschienen angeordneten Storenbehang mit einer Mehrzahl von Lamellen, eine den Storenbehang abschliessende Unterschiene, und wenigstens eine Aufzugsvorrichtung. Die Lamellen weisen jeweils eine abschliessende Blendenfläche und eine hierzu im oberen Abschnitt angewinkelte Oberkante auf, wobei die angewinkelte Oberkante mit jeweils seitlich vorragenden Führungszapfen bereitgestellt ist, über welche die Lamellen verschwenkbar in den Führungsschienen geführt sind. Die abschliessende Blendenfläche ragt derart über die angewinkelte Oberkante seitlich vor, dass vorragende Abschnitte der Blendenfläche in geschlossenem Zustand der Lamellenstore mit den Führungsschienen in Anlage bringbar sind und mit den Führungsschienen überlappt sind, so dass durch diese Überlappung kein direktes Licht zwischen der Lamelle und den seitlichen Führungsschienen einfällt.This object is achieved by a slat according to claim 1 and a slat blind, comprising: laterally arranged guide rails, a blind curtain with a plurality of slats arranged between the guide rails, a lower rail closing the blind curtain, and at least one elevator device. The slats each have a closing panel surface and an upper edge angled for this purpose in the upper section, the angled upper edge being provided with laterally protruding guide pins over which the slats are pivotably guided in the guide rails. The concluding panel surface protrudes laterally over the angled upper edge in such a way that protruding sections of the panel surface can be brought into contact with the guide rails when the blind is closed and are overlapped with the guide rails, so that this overlap does not result in direct light between the slats and the lateral ones Guide rails collapses.

Die Lamellenstore gemäss der vorliegenden Erfindung erlaubt eine nahezu vollständige Verdunkelung, da die einzelnen Lamellen im geschlossenen Zustand mit Ihren Blendenflächen seitlich mit den beiden Führungsschienen in Anlage gebracht sind. Mit anderen Worten, überlappen sich die Endseiten der Lamellen mit den Führungsschienen, sodass, gegenüber dem Stand der Technik, bei welchem die Unterschiene beispielsweise mittig gelagert wird, bzw. der Drehpunkt der Lamellen auf deren Blendenfläche liegt, kein Spalt entsteht, durch welchen direktes Licht in das Gebäudeinnere einfallen kann. Dieser Vorteil stellt sich dadurch ein, indem die Führungszapfen jeweils an einem Abschnitt der Lamellen angebracht sind, hier als Oberkante definiert, welcher gegenüber der Blendenfläche angewinkelt ist. Soweit keine weiteren Kräfte oder Drehmomente an die Lamellen anliegen, schwenken die einzelnen Lamellen durch Schwerkraft herunter und werden durch Aussenflächen der Führungsschienen abgestützt, bzw. gelangen die Blendenflächen der einzelnen Lamellen mit ihrer Rückseite hiermit in Anlage. Die Oberkante kann gegenüber der Blendenfläche in einem Winkel in einem Bereich von 50° bis 90° angewinkelt sein, vorzugsweise im Wesentlichen 70°. Während dem Heben und Absenken der Lamellen wird die Unterschiene in horizontaler Stellung beibehalten, um somit auch den Lamellenstapel in horizontaler Stellung zu halten. Sobald sich die Unterschiene in unterster Stellung befindet, kann auch die Unterschiene verschwenkt werden. Dies ist allerdings nicht zwingend notwendig. Die Unterschiene kann auch nicht-verschwenkbar sein.The slat blind according to the present invention allows almost complete darkening, since the individual slats in the closed state with their faceplate surfaces are laterally brought into contact with the two guide rails. In other words, the end faces of the Slats with the guide rails, so that, compared to the prior art, in which the bottom rail For example, it is mounted in the middle, or the fulcrum of the slats is on their faceplate, no gap is created through which direct light can enter the building interior. This advantage is achieved in that the guide pins are each attached to a section of the lamellas, here defined as the upper edge, which is angled with respect to the faceplate. As long as no further forces or torques are applied to the slats, the individual slats swing down by gravity and are supported by the outer surfaces of the guide rails, or the faceplate surfaces of the individual slats come into contact with their rear side. The upper edge can be angled at an angle in a range from 50 ° to 90 °, preferably substantially 70 °, with respect to the screen surface. During the lifting and lowering of the slats, the lower rail is kept in a horizontal position in order to keep the slat stack in a horizontal position. As soon as the lower rail is in the lowest position, the lower rail can also be pivoted. However, this is not absolutely necessary. The lower rail can also be non-pivotable.

Die erfindungsgemässe Lamellenstore erlaubt im geschlossenen Zustand einen Verdunkelungsgrad, welcher ähnlich dem eines Rollladens sein kann - allerdings mit einem ganz wesentlichen Vorteil gegenüber einem Rollladen, dass nämlich die Lamellen jederzeit einfach geneigt werden können, damit Licht ins Gebäudeinnere einfällt und es dem Benutzer ermöglicht wird, nahezu ungestört nach Aussen schauen zu können. Die Licht-/Helligkeit-Regulierung der erfindungsgemässen Lamellenstore ist gegenüber Rollladen stark verbessert. Damit ist erstmals eine überaus zuverlässige Lamellenstore geschaffen, welche mit einfachen Mitteln eine nahezu vollständige Verdunkelung und zudem eine sehr umfassende Licht-/Helligkeit-Regulierung bietet.The slat blind according to the invention allows a degree of darkening in the closed state, which can be similar to that of a roller shutter - but with a very significant advantage over a roller shutter, namely that the slats can simply be tilted at any time so that light can enter the interior of the building The user is able to look outside almost undisturbed. The light / brightness regulation of the slat blinds according to the invention is greatly improved compared to roller shutters. This is the first time that an extremely reliable slat blind has been created, which offers almost complete darkening with simple means and also very comprehensive light / brightness regulation.

Die erfindungsgemässe Lamellenstore erlaubt ferner vorteilhafterweise einen vollständigen Sichtschutz von aussen ins Gebäudeinnere. Die erfindungsgemässe Lamellenstore hat zudem ein einbruchhemmendes Erscheinungsbild, weil Sie im geschlossenen Zustand von aussen wie ein Rollladen aussieht. Zudem stören keine Sicken oder Biegekanten im sichtbaren Behangbereich die Ästhetik.The slatted blind according to the invention also advantageously allows complete privacy protection from the outside into the interior of the building. The slatted blind according to the invention also has a burglar-resistant appearance because when closed it looks like a roller shutter from the outside. In addition, there are no beads or bending edges in the visible area of the curtain to disturb the aesthetics.

In einer Ausführungsform sind einander vertikal angrenzende Lamellen wenigstens abschnittsweise überlappt. Hierbei liegen untere Kantenabschnitte der Blendenflächen jeweils auf oberen Kantenabschnitten von Blendenfläche von jeweils unterhalb angeordneten Lamellen an. Bei einem vollständig heruntergefahrenen Storenbehang kann die Überlappung der jeweils angrenzenden Lamellen minimal sein, jedoch immer noch ausreichend, um das Eindringen von Licht zu verhindern.In one embodiment, vertically adjoining lamellae are overlapped at least in sections. In this case, lower edge sections of the diaphragm surfaces each rest on the upper edge portions of the diaphragm surface of lamellas arranged below. When the blinds are completely lowered, the overlap of the adjacent slats can be minimal, but still sufficient to prevent light from entering.

Vorzugsweise enthält die Aufzugsvorrichtung wenigstens einen Riemenantrieb oder einen Bandaufzug. Der Riemenantrieb ist im Bereich der Führungsschienen angeordnet. Beispiele eines Riemenantriebs sind ein Zahnriemenantrieb, ein Lochriemenantrieb, usw. Alternativ zum Riemenantrieb kann der Bandaufzug vorgesehen sein, welcher die Unterschiene über Aufzugsbänder anhebt oder absenkt. Der Bandaufzug kann in einem jeglichen Abschnitt zwischen den beiden Führungsschienen angeordnet sein.The elevator device preferably contains at least one belt drive or a belt elevator. The belt drive is arranged in the area of the guide rails. Examples of a belt drive are a toothed belt drive, a perforated belt drive, etc. As an alternative to the belt drive, the belt elevator can be provided, which raises or lowers the lower rail via elevator belts. The tape elevator can be arranged in any section between the two guide rails.

Vorzugsweise enthält die Aufzugsvorrichtung wenigstens eine elektrisch und/oder manuell antreibbare Antriebsvorrichtung. Somit können die Lamellen des Storenbehangs per Motorkraft oder per Hand herauf- und herunterbewegt werden und optional in ihrer Neigung variiert werden. Beispielhafte Stellglieder zum manuellen Antreiben der Aufzugsvorrichtung können eine Kurbel oder eine Aufzugsschnur aufweisen. Eine elektrisch antreibbare Antriebsvorrichtung kann einen Elektromotor aufweisen, welcher den Storenbehang durch Motorkraft anhebt oder absenkt. Ebenso können die Lamellen durch elektrischen Antrieb in ihrer Neigung verändert werden.The elevator device preferably contains at least one electrically and / or manually drivable drive device. This means that the slats of the blinds can be moved up and down by motor power or by hand, and their inclination can optionally be varied. Exemplary actuators for manually driving the elevator device can include a crank or an elevator cord. An electrically drivable drive device can have an electric motor which raises or lowers the blind curtain by motor power. The inclination of the slats can also be changed by an electric drive.

Vorzugsweise, in einer Ausführung, bei welcher die Aufzugsvorrichtung den wenigstens einen Riemenantrieb enthält, enthält der Riemenantrieb wenigstens ein Zahnrad, welches mit der Antriebsvorrichtung gekoppelt ist, und wenigstens einen Riemen, wobei der Riemen am unteren Ende mit der Unterschiene gekoppelt ist und am weiteren Ende wenigstens abschnittsweise mit Zähnen des Zahnrads in Eingriff steht. Der Riemen kann ein Lochriemen, ein Zahnriemen, usw. sein. Der Riemenantrieb zeichnet sich dadurch aus, dass er hohe Kräfte aufnehmen kann.Preferably, in an embodiment in which the elevator device contains the at least one belt drive, the belt drive contains at least one toothed wheel, which is coupled to the drive device, and at least one belt, the belt being coupled at the lower end to the lower rail and at the further end is at least partially in engagement with teeth of the gear. The belt can be a perforated belt, a toothed belt, etc. The belt drive is characterized by the fact that it can absorb high forces.

Vorzugsweise sind die Riemen jeweils innerhalb der Führungsschienen geführt. Die Riemen können aus einem elastischen Kunststoffmaterial hergestellt sein. In einem Beispiel wird ein elastischer Riemen, z.B. der Lochriemen, um 180° um das Zahnrad geführt und gelangt somit in zuverlässiger Anlage hiermit. In einem weiteren Beispiel kann der Riemen aus einem abriebfesten Kunststoffmaterial hergestellt sein.The belts are preferably each guided within the guide rails. The straps can be made of an elastic plastic material. In one example, an elastic strap, e.g. the perforated belt, guided 180 ° around the gear and thus comes into reliable contact with it. In another example, the belt can be made from an abrasion-resistant plastic material.

Vorzugsweise, in einer Ausführung, bei welcher die Aufzugsvorrichtung den wenigstens einen Bandaufzug enthält, enthält der Bandaufzug ein Aufzugsband, welches an einem Ende mit der Unterschiene gekoppelt ist und am weiteren Ende wenigstens abschnittsweise durch den wenigstens einen Bandaufzug aufwickelbar oder abwickelbar ist. Somit wird die Unterschiene durch die Bandaufzüge und jeweils zugeordnete Aufzugsbänder zuverlässig abgehoben und abgesenkt.Preferably, in an embodiment in which the elevator device contains the at least one tape elevator, the tape elevator contains an elevator tape which is coupled at one end to the lower rail and at least in sections can be wound or unwound at the other end by the at least one tape elevator. Thus, the lower rail is reliably lifted and lowered by the belt lifts and the respectively assigned lift belts.

Vorzugsweise enthält die Lamellenstore ferner wenigstens einen Seilaufzug zum Aufwickeln oder Abwickeln von einem mit der Unterschiene gekoppelten Seil. Diese Ausführungsform wird bei einer Lamellenstore angewendet, bei welcher die Aufzugsvorrichtung den wenigstens einen Riemenantrieb enthält. Mittels des Seilaufzugs wird die Unterschiene gegen ein Durchbiegen gestützt. In einem Beispiel kann der Seilantrieb mittig zwischen den Führungsschienen angeordnet sein.The slatted blind preferably also contains at least one cable elevator for winding or unwinding a cable coupled to the lower rail. This embodiment is used for a venetian blind, in which the elevator device contains the at least one belt drive. The lower rail is supported against bending by means of the cable lift. In one example, the cable drive can be arranged centrally between the guide rails.

Vorzugsweise enthält der wenigstens eine Seilantrieb eine umdrehbare Walze, welche mit der Antriebsvorrichtung gekoppelt ist, wobei das Seil an einem Ende mit der Unterschiene gekoppelt ist und am weiteren Ende wenigstens abschnittsweise auf dem Umfang der Walze aufwickelbar ist. Die Walze kann durch ein angelegtes Drehmoment von einem hiermit gekoppelten Elektromotor umdreht werden.The at least one cable drive preferably contains a rotatable roller which is coupled to the drive device, the cable being coupled to the lower rail at one end and being able to be wound at least in sections on the circumference of the roller at the other end. The roller can be rotated by an applied torque from an electric motor coupled to it.

Vorzugsweise sind die angewinkelten Oberkanten der Lamellen jeweils mit wenigstens einer Durchbohrung versehen, und ist das Seil oder das Aufzugsband im Verlauf zwischen dem Seilantrieb und der Unterschiene bzw. zwischen dem Bandaufzug und der Unterschiene durch diese Durchbohrungen geführt. Ein ganz wesentlicher Vorteil dieser Ausführungsform besteht darin, dass das Aufzugsband oder das Seil im geschlossenen Zustand des Storenbehangs, bei gleichzeitig in die Verdunklungsstellung geneigten Lamellen, von aussen betrachtet vollständig hinter der Blendenfläche des Storenbehangs verläuft. Somit ist das Aufzugsband oder das Seil im geschlossenen Zustand (d.h. im Beschattungszustand) des Storenbehangs keiner UV-Strahlung ausgesetzt. Hierdurch ist das Aufzugsband oder das Seil wirksam gegen UV-Strahlung geschützt und werden Alterungsprozesse des Aufzugsbandes oder des Seils vorteilhafterweise stark verzögert, wodurch der Verschleiss hiervon stark verringert wird. Hierdurch wird die Lebensdauer des Aufzugsbandes oder des Seils wesentlich verlängert. Ein weiterer Vorteil besteht darin, dass, im vollständig geschlossenen Zustand des Storenbehangs, die Durchbohrungen zum Durchführen des Aufzugsbandes oder des Seils nicht der Aussenseite ausgesetzt sind. Hierdurch kann kein Licht durch diese Durchbohrungen in das Gebäudeinnere einfallen. Ebenso kann von aussen kein unerlaubter Blick in das Gebäudeinnere geworfen werden. Somit ist eine Lamellenstore geschaffen, welche eine vollständige Verdunkelung und einen vollständigen Sichtschutz ermöglicht.The angled upper edges of the slats are preferably each provided with at least one through-hole, and the rope or the elevator belt is guided through these through-holes in the course between the cable drive and the lower rail or between the belt elevator and the lower rail. A very significant advantage of this embodiment is that the elevator tape or the rope in the closed state of the blinds, with the slats inclined into the darkening position, runs completely behind the face of the blinds when viewed from the outside. The elevator tape or the rope is therefore not exposed to any UV radiation in the closed state (ie in the shaded state) of the blind curtain. As a result, the elevator tape or the rope is and are effectively protected against UV radiation Aging processes of the elevator tape or of the rope are advantageously greatly delayed, whereby the wear thereof is greatly reduced. This significantly extends the service life of the elevator tape or rope. Another advantage is that, in the completely closed state of the blind curtain, the through-holes for passing the elevator tape or the rope are not exposed to the outside. As a result, no light can enter the interior of the building through these perforations. Likewise, no unauthorized look inside the building can be thrown from the outside. Thus, a slat blind is created which enables complete darkening and complete privacy protection.

Vorzugsweise ist der Seilantrieb in einem Abschnitt von der Lamellenstore angeordnet, welcher von den Führungsschienen versetzt ist. Hierdurch kann bei insbesondere langen Unterschienen vermieden werden, dass sich diese mittig durchbiegen werden.The cable drive is preferably arranged in a section of the slatted blind which is offset from the guide rails. In this way, in the case of especially long lower rails, it can be avoided that these are bent in the middle.

Vorzugsweise ist der von den Führungsschienen versetzte Seilantrieb dazu eingerichtet, die Unterschiene mit einer Geschwindigkeit anzuheben bzw. abzusenken, mit welcher die in den Führungsschienen eingerichteten Riemenantriebe die Unterschiene anheben bzw. absenken. Hierdurch wird vorteilhafterweise eine Synchronität zwischen den Antrieben sichergestellt und kann vermieden werden, dass die Unterschiene entlang ihrer gesamten Länge mit unterschiedlichen Geschwindigkeiten angehoben bzw. abgesenkt wird und hierdurch möglicherweise verbogen wird.The cable drive offset from the guide rails is preferably set up to raise or lower the lower rail at a speed at which the belt drives installed in the guide rails raise or lower the lower rail. This advantageously ensures synchronicity between the drives and it can be avoided that the bottom rail along its entire length with is raised or lowered at different speeds and may be bent as a result.

Vorzugsweise ist der von den Führungsschienen versetzte Seilantrieb dazu eingerichtet, das Seil einlagig aufgereiht auf dem Umfang von der Walze entlang einer Längsrichtung hiervon aufzuwickeln. Hierdurch wird vermieden, dass sich das Seil übereinander aufwickelt, welches den Nachteil hätte, dass sich durch den hierdurch stetig vergrössernden Durchmesser auch die relative Geschwindigkeit vergrössert, mit welcher die Unterschiene, z.B. in der Mitte hiervon, angehoben wird. Mit relativer Geschwindigkeit ist hiermit Bezug auf die Geschwindigkeit genommen, mit welcher der Storenbehang an den Seiten (Führungsschienen) bewegt wird. Indem das Seil einlagig, d.h. stets spiralförmig, aufgereiht wird, während es auf der Walze aufgewickelt wird, kann zuverlässig verhindert werden, dass sich der Wickeldurchmesser vergrössern wird. Mit anderen Worten, wird das Seil immer mit der gleichen Geschwindigkeit aufgewickelt und abgewickelt, wobei die Geschwindigkeit synchron ist zur Geschwindigkeit weiterer Aufzugsvorrichtungen, beispielsweise die im Bereich der Führungsschienen angeordneten Riemenantriebe.The cable drive offset from the guide rails is preferably set up to wind up the cable, lined up in one layer, on the circumference of the roller along a longitudinal direction thereof. This avoids the rope winding up on top of each other, which would have the disadvantage that the constantly increasing diameter also increases the relative speed at which the lower rail, e.g. in the middle of this, is raised. Relative speed refers to the speed at which the blind curtain is moved on the sides (guide rails). By making the rope in a single layer, i.e. is always spirally lined up while it is being wound on the roller, the winding diameter can be reliably prevented from increasing. In other words, the rope is always wound and unwound at the same speed, the speed being synchronous with the speed of other elevator devices, for example the belt drives arranged in the area of the guide rails.

Vorzugsweise umfasst die Lamellenstore ferner wenigstens eine Wendeeinrichtung zur Neigungsverstellung von wenigstens einer der Lamellen. Hierdurch wird der Neigungswinkel der Lamellen zuverlässig verändert, und zwar in einem Bereich zwischen einer vollständigen Verdunkelung (im Wesentlichen vertikalen Ausrichtung) und einer im Wesentlichen horizontalen Ausrichtung. Somit kann der Benutzer, unabhängig von der Stellung des Storenbehangs, schnell und einfach den Lichteinfall regulieren und einen Blick nach aussen werfen.The slat blind preferably further comprises at least one turning device for adjusting the inclination of at least one of the slats. As a result, the angle of inclination of the slats is reliably changed, namely in a range between complete darkening (essentially vertical orientation) and an essentially horizontal orientation. Thus, regardless of the position of the blinds, the user can quickly and easily regulate the incidence of light and take a look outside.

Vorzugsweise enthält die Lamellenstore ferner einen Hebelmechanismus, eingerichtet zum Übersetzen einer im Wesentlichen linearen Bewegung in eine Kippbewegung zur Neigungsverstellung der Unterschiene. Die Unterschiene ist endseitig über die angewinkelte Oberseite (exzentrisch) aufgehängt, bzw. gelagert. Daher muss, gegenüber einer Lösung, bei welcher die Unterschiene beispielsweise mittig gelagert ist, eine grössere Kraft angelegt werden, um die Unterschiene im frei hängenden Zustand in Richtung zur horizontalen Ausrichtung zu neigen. Hierzu ist der Hebelmechanismus zur Kraftübersetzung bereitgestellt. Der Hebelmechanismus kann beispielsweise als ein Kniehebel ausgeführt sein, welcher eine im Wesentlichen lange lineare Bewegung in eine relativ kurze Kippbewegung mit übersetzter hoher Kraft erzeugt. Der Hebelmechanismus kann ein jeglicher Mechanismus mit hoher Kraftübersetzung bzw. Drehmomentübersetzung sein.The slatted blind preferably also contains a lever mechanism, set up to translate a substantially linear movement into a tilting movement for adjusting the inclination of the lower rail. The bottom rail is suspended or stored at the end over the angled upper side (eccentrically). Therefore, compared to a solution in which the lower rail is mounted in the middle, for example, a greater force must be applied in order to incline the lower rail in the freely hanging state in the direction of horizontal alignment. For this purpose, the lever mechanism is provided for power transmission. The lever mechanism can be designed, for example, as a toggle lever, which generates an essentially long linear movement into a relatively short tilting movement with an increased force. The lever mechanism can be any mechanism with a high power transmission or torque transmission.

Vorzugsweise umfasst die Lamellenstore ferner einen Schlitten zur Aufnahme von dem Hebelmechanismus, wobei der Schlitten wenigstens abschnittsweise zusammen mit der Unterschiene entlang der Führungsschiene verfahrbar ist. Der Hebelmechanismus folgt somit der vertikalen Richtung, in welche die Unterschiene entlang der Führungsschiene bewegt wird.The slat blind preferably further comprises a slide for receiving the lever mechanism, the slide being movable at least in sections together with the lower rail along the guide rail. The lever mechanism thus follows the vertical direction, in which the lower rail is moved along the guide rail.

Vorzugsweise enthält die Wendeeinrichtung eine Kugelschnur und eine Umlenkeinrichtung, welche eingerichtet ist, die Kugelschnur derart umzulenken, dass im Wesentlichen parallele Verläufe derer voneinander vorbestimmt beabstandet sind. Hierdurch kann gegenüber vorbekannten Lösungen der Abstand zwischen den vertikalen Verläufen der Kugelschnur vergrössert werden. Dieser vergrösserte Abstand erlaubt eine einfachere Bedienung, um die Lamellen einfacher zu Schwenken.The turning device preferably contains a ball cord and a deflection device which is set up to deflect the ball cord in such a way that essentially parallel courses thereof are at a predetermined distance from one another. As a result, the distance between the vertical courses of the ball cord can be increased compared to previously known solutions. This increased distance allows easier operation in order to pivot the slats more easily.

Lediglich diejenigen Kombinationen von Ausführungsvarianten sind ausgeschlossen, die durch die Kombination zu Widersprüchen führen würden.It is expressly pointed out that the above design variants can be combined as required. Only those combinations of design variants that would lead to contradictions through the combination are excluded.

Figuren 1a,b zeigen jeweils eine Lamellenstore 10 in einer ersten Ausführungsform der Erfindung in unterschiedlichen Ansichten. Die Lamellenstore 10 enthält zwei Führungsschienen 12 (aus darstellhaften Gründen ist nur eine Führungsschiene gezeigt) zum vertikalen Führen eines zwischen den Führungsschienen 12 angeordneten Storenbehangs 14, welcher wiederum eine Mehrzahl von Lamellen 16'-16''' enthält. In den Figuren 1a,b ist die Lamellenstore 10 im geöffneten Zustand des Storenbehangs 14 gezeigt. Obwohl in der Zeichnung nur drei Lamellen 16'-16''' gezeigt sind, enthält eine typische Lamellenstore 10 bedeutend mehr Lamellen. Figures 1a, b each show a slat blind 10 in a first embodiment of the invention in different ways Views. The slat blind 10 contains two guide rails 12 (for reasons of illustration only one guide rail is shown) for vertically guiding a blind curtain 14 arranged between the guide rails 12, which in turn contains a plurality of slats 16'-16 '''. In the Figures 1a, b the slat blind 10 is shown in the open state of the blind curtain 14. Although only three slats 16'-16 "'are shown in the drawing, a typical venetian blind 10 contains significantly more slats.

Der Storenbehang 14 wird unterhalb von einer Unterschiene 18 abgeschlossen. Die Unterschiene 18 wird in dem gezeigten Beispiel über ein hiermit verbundenes Seil 20 mittig gestützt, so dass die Unterschiene 18 nicht durchhängen wird. Das Seil 20 wird hierbei auf dem Umfang einer Walze (nicht gezeigt) von einem Seilaufzug 22 aufgewickelt oder abgewickelt. Durch den Seilaufzug 22 wird somit verhindert, dass insbesondere bei sehr breiten Lamellenstoren 10 die (lange) Unterschiene 18 in der Mitte durchhängen bzw. durchgebogen wird, wie im Folgenden detaillierter beschrieben.The blind curtain 14 is closed below by a lower rail 18. In the example shown, the lower rail 18 is supported in the center via a rope 20 connected to it, so that the lower rail 18 will not sag. The rope 20 is wound or unwound from a cable elevator 22 on the circumference of a roller (not shown). The cable elevator 22 thus prevents the (long) lower rail 18 from sagging or being bent in the middle, in particular in the case of very wide slat blinds 10, as described in more detail below.

Die Unterschiene 18 wird mittels einem Riemenantrieb 24, welcher in der Führungsschiene 12 integriert ist (im Folgenden detaillierter beschrieben), herauf und herunter bewegt. Beim Heraufbewegen der Unterschiene 18 werden sequentiell jeweils übereinander positionierte Lamellen aufgenommen und mit der Unterschiene 18 und bereits aufgenommenen Lamellen weiter nach oben bewegt, bis auch diese Lamelle eine vormals übergeordnete Lamelle aufnimmt, und so weiter (allgemein als Raffstoren-Prinzip bekannt). Das Paket aus den Lamellen und der Unterschiene 18 selber kann insgesamt ein hohes Gewicht annehmen, welches zuverlässig durch den Riemenantrieb 24 an den Seiten aufgenommen wird. Der Riemenantrieb 24 enthält ein Zahnrad 26, welches zur Umdrehung antreibbar ist. Das Zahnrad 26 steht mit einem Riemen 28 in Eingriff, welcher innerhalb der Führungsschiene 12 geführt ist. Der Riemen 28 ist wiederum am unteren Ende mit der Unterschiene 18 gekoppelt. Bei einer Umdrehung des Zahnrads 26 wird somit die Drehbewegung in eine lineare Bewegung des Riemens 28 zum Heben oder Absenken der Unterschiene 18 überführt. In dem gezeigten Beispiel ist der Riemen 28 als Lochriemen ausgebildet.The lower rail 18 is moved up and down by means of a belt drive 24 which is integrated in the guide rail 12 (described in more detail below). When the lower rail 18 is moved up, slats positioned one on top of the other are sequentially picked up and with the lower rail 18 and already recorded slats are moved further upwards until this slat also receives a previously higher-level slat, and so on (generally known as the external venetian blind principle). The package of the lamellas and the lower rail 18 itself can assume a high overall weight, which is reliably absorbed by the belt drive 24 on the sides. The belt drive 24 contains a toothed wheel 26 which can be driven to rotate. The gear wheel 26 engages with a belt 28 which is guided within the guide rail 12. The belt 28 is in turn coupled to the lower rail 18 at the lower end. During one revolution of the gear wheel 26, the rotary movement is thus converted into a linear movement of the belt 28 for raising or lowering the lower rail 18. In the example shown, the belt 28 is designed as a perforated belt.

Die Lamellenstore 10 enthält ebenso zwei Wendeeinrichtungen 30',30" zur Neigungsverstellung der Lamellen 16'-16"', wie im Folgenden detaillierter erläutert. Hierzu sind wenigstens die einzelnen Lamellen 16'-16''' abschnittsweise entlang ihrer Längsseiten, an jeweils gegenüberliegenden Stellen, mit Kordeln 32a',32b' und 32a",32b" gekoppelt. Die Lamellen 16'-16'" haben jeweils eine Blendenfläche und eine hierzu angewinkelte Oberkante. Die Blendenflächen der einzelnen Lamellen 16'-16''' bilden hierbei in ihrer Gesamtheit die nach Aussen zugewandte Lamellenstore-Aussenfläche, wie in Figuren 2a-c gezeigt, welche die Lamellenstore 10 gemäss der ersten Ausführungsform im geschlossenen Zustand des Storenbehangs 14 darstellen. Die angewinkelte Oberkante ist nach innen gerichtet angekantet und schliesst mit der jeweiligen Blendenfläche einen Winkel in einem Bereich von 50° bis 90°, im Wesentlichen 70°, ein. Die einzelnen Oberkanten weisen jeweils seitlich vorragende Führungszapfen 34'-34''' auf. Die einzelnen Lamellen 16'-16'" werden über ihre Führungszapfen 34'-34''' verschwenkbar und vertikal verstellbar in den Führungsschienen 12 geführt. Hierzu weisen die Führungsschienen 12 jeweils eine vertikal verlaufende Aussparung auf.The slat blind 10 also contains two turning devices 30 ', 30 "for adjusting the inclination of the slats 16'-16"', as explained in more detail below. For this purpose, at least the individual lamellas 16'-16 '''are coupled in sections along their longitudinal sides at opposite points with cords 32a', 32b 'and 32a ", 32b". The slats 16'-16 '"each have a panel surface and an upper edge angled to it. The panel surfaces of the individual slats 16'-16'"'here in their entirety form the external surface of the external blind facing, as in FIG Figures 2a-c shown, which the slat blinds 10 according to the first embodiment in represent the closed state of the blind curtain 14. The angled upper edge is canted inwards and forms an angle with the respective faceplate in a range from 50 ° to 90 °, essentially 70 °. The individual upper edges each have laterally protruding guide pins 34'-34 '''. The individual lamellas 16'-16 '"are guided in the guide rails 12 in a pivotable and vertically adjustable manner via their guide pins 34'-34"'. For this purpose, the guide rails 12 each have a vertically extending recess.

Erfindungsgemäss ragt die Blendenfläche über die angewinkelte Oberkante seitlich vor (siehe hierzu insbesondere Figuren 2b-e). Hierbei ragen die Blendenflächen derart vor, dass deren Rückflächen jeweils mit den Führungsschienen 12 in Anlage bringbar sind (siehe insbesondere Figuren 2b,c). Mit anderen Worten, überlappen sich also die jeweils seitlich vorragenden Abschnitte der Blendenflächen mit Abschnitten der jeweils zugeordneten Führungsschiene 12. Durch diese Überlappung fällt kein Licht zwischen den Lamellen 16'-16''' und den seitlichen Führungsschienen 12 ins Innere des Gebäudes ein. Gegenüber dem Stand der Technik, in welchem sich ein Spalt zwischen den Lamellen 16'-16''' und den Führungsschienen 12 einstellt, ist somit insgesamt ein wesentlich höherer Verdunkelungsgrad der Lamellenstore 10 geschaffen.According to the invention, the panel surface protrudes laterally over the angled upper edge (see in particular Figures 2b-e ). Here, the panel surfaces protrude in such a way that their rear surfaces can each be brought into contact with the guide rails 12 (see in particular Figures 2b, c ). In other words, the laterally protruding sections of the panel surfaces overlap with sections of the respectively assigned guide rail 12. Due to this overlap, no light penetrates into the interior of the building between the slats 16'-16 '''and the lateral guide rails 12. Compared to the prior art, in which a gap is established between the slats 16'-16 '''and the guide rails 12, a significantly higher degree of darkening of the slat blinds 10 is thus created overall.

In Figuren 2d,e ist jeweils die Lamellenstore 10 in einer zweiten Ausführungsform gezeigt. In dieser zweiten Ausführungsform wird die Unterschiene 18 über zwei Bandaufzüge 35',35" heraufbewegt bzw. herunterbewegt. Hierzu werden Aufzugsbänder 36',36", welche jeweils an der Unterschiene 18 fixiert sind, durch den jeweils zugeordneten Bandaufzug 35',35" aufgewickelt bzw. abgewickelt. In der gezeigten Ausführungsform sind die Wendeeinrichtungen 30',30" und Bandaufzüge 35',35" jeweils zu einer Einheit integriert. Obwohl nicht gezeigt, können die Wendeeinrichtungen 30',30" und Bandaufzüge 35',35" getrennt sein. Unabhängig ob gemeinsam integriert oder separat, können auch mehr als zwei Wendeeinrichtungen 30',30" und Bandaufzüge 35',35" vorgesehen sein. In der in Figuren 2d,e gezeigten Ausführungsform ist die Unterschiene 18 nicht verschwenkbar gelagert. Hierbei sind lediglich die Lamellen 16'-16''' verschwenkbar.In Figures 2d, e each of the slat blinds 10 is shown in a second embodiment. In this second embodiment, the lower rail 18 is moved up or down via two belt lifts 35 ', 35 ". For this purpose, lift tapes 36', 36", which are each fixed to the lower rail 18, are wound up by the respectively assigned belt lift 35 ', 35 " In the embodiment shown, the turning devices 30 ', 30 "and belt lifts 35', 35" are each integrated into a unit. Although not shown, the turning devices 30 ', 30 "and belt lifts 35', 35" can be separate Regardless of whether they are integrated together or separately, more than two turning devices 30 ', 30 "and belt lifts 35', 35" can also be provided Figures 2d, e The embodiment shown, the lower rail 18 is not pivoted. Only the lamellae 16'-16 '''can be pivoted here.

Wie in Figuren 2b,e gezeigt, ist die Oberkante jeweils der Lamellen 16'-16''' mit wenigstens einer Durchbohrung 37, auch als Lamellenstanzung bezeichnet, versehen (in Figur 2b aus darstellhaften Gründen nur bei Lamelle 16' zu erkennen). Die Durchbohrung 37 dient zum Durchführen des Seils 20 (siehe die in Figuren 2a-c gezeigte erste Ausführungsform) oder des Aufzugsbandes 36'-36" (siehe die in Figuren 2d,e gezeigte zweite Ausführungsform). Im Unterschied zum Stand der Technik, verläuft das Seil 20 oder verlaufen die Aufzugsbänder 36'-36" somit (im geschlossenen Zustand des Storenbehangs 14) gänzlich hinter der Blendenfläche.As in Figures 2b , e As shown, the upper edge of each of the lamellae 16'-16 '''is provided with at least one through hole 37, also referred to as a lamella punching (in Figure 2b for illustrative reasons only to be seen with lamella 16 '). The through hole 37 is used to pass through the rope 20 (see the in Figures 2a-c first embodiment shown) or the elevator tape 36'-36 "(see the in Figures 2d, e second embodiment shown). In contrast to the prior art, the rope 20 or the elevator tapes 36'-36 "thus run (in FIG closed state of the blind curtain 14) completely behind the screen surface.

Hieraus ergibt sich der Vorteil, dass im geschlossenen Zustand des Storenbehangs 14 keine Durchbohrungen zum Führen des Seils 20 oder Aufzugsbandes 36',36" der Aussenseite ausgesetzt sind, durch welche Durchbohrungen Licht einfallen kann. Mit anderen Worten, fällt im Bereich des Seilaufzugs 22 oder des Bandaufzugs 35',35" kein Licht ins Innere des Gebäudes ein. Somit ermöglicht die Lamellenstore 10 eine vollständige Verdunkelung, wie im Stand der Technik bislang unerreicht.This results in the advantage that in the closed state of the blind curtain 14 no through-holes for guiding the cable 20 or elevator tape 36 ', 36 "are exposed on the outside through which through-holes light can enter of the belt elevator 35 ', 35 "does not allow light into the interior of the building. The slat blind 10 thus enables complete darkening, as has been previously unattainable in the prior art.

Weiter vorteilhaft verläuft das Seil 20 (siehe Figuren 2a-c) oder verlaufen die Aufzugsbänder 36',36" (siehe Figuren 2d,e) im geschlossenen Zustand des Storenbehangs 14 vollständig im inneren Bereich der Lamellen 16'-16''' und ist bzw. sind somit vor UV-Einwirkung geschützt. Somit wird das Seil 20 bzw. werden die Aufzugsbänder 36',36" gegen vorzeitigen Verschleiss geschützt. Im Vergleich zum Stand der Technik wird somit zuverlässig verhindert, dass das Seil 20 vorschnell reissen wird bzw. die Aufzugsbänder 36',36" vorschnell reissen werden.The rope 20 (see FIG Figures 2a-c ) or run the elevator bands 36 ', 36 "(see Figures 2d, e ) in the closed state of the blind curtain 14 completely in the inner area of the slats 16'-16 '''and is or are thus protected from UV exposure. Thus, the rope 20 or the elevator tapes 36 ', 36 "are protected against premature wear. Compared to the prior art, this reliably prevents the rope 20 from breaking prematurely or the elevator tapes 36', 36" from breaking prematurely .

Figuren 3a-d zeigen jeweils eine Seitenansicht auf die verschwenkbare Unterschiene 18 zur Verdeutlichung eines Hebelmechanismus 38 zum hebelmässigen Unterstützen der Aufrichtung von der Unterschiene 18 von der im Wesentlichen vertikalen Ausrichtung (siehe Figur 3a) in eine im Wesentlichen horizontale Ausrichtung (siehe Abläufe in Figuren 3b-d). In Figuren 4a-d und 5a-d sind Detailansichten von dem Hebelmechanismus 38 gezeigt. Da die Unterschiene 18 endseitig, d.h. exzentrisch, über ihre Führungszapfen (siehe z.B. Figur 1b) aufgehängt bzw. gelagert ist, muss, gegenüber einer Lösung, bei welcher eine Unterschiene 18 im Wesentlichen mittig gelagert ist, eine verstärkte Kraft angelegt werden, um die Unterschiene 18 aufzurichten. Hierbei unterstützt der Hebelmechanismus 38, welcher, gleich dem Prinzip eines Kniehebels, die Unterschiene 18 in die horizontale Stellung (und umgekehrt in die vertikale Stellung) überführt. Ein Ausleger 40 bzw. Hebelarm des Hebelmechanismus 38 greift hierbei gelenkig an einen Mittenabschnitt 42 von der Unterschiene 18 an, um gemäss dem Prinzip eines verlängerten Hebelarms eine verstärkte Druckkraft zum Aufrichten der Unterschiene 18 anzulegen. Der Hebelmechanismus 38 ist in einem Schlitten 43 aufgenommen, über welchen der Hebelmechanismus 38 zusammen mit der Unterschiene 18 entlang der Führungsschiene 12 verfahrbar ist. Figures 3a-d each show a side view of the pivotable lower rail 18 to illustrate a lever mechanism 38 for lever-like support of the erection of the lower rail 18 from the substantially vertical alignment (see Figure 3a ) in an essentially horizontal orientation (see processes in Figures 3b-d ). In Figures 4a-d and 5a-d detailed views of the lever mechanism 38 are shown. Since the lower rail 18 ends, ie eccentrically, via its guide pin (see e.g. Figure 1b ) is suspended or stored, in contrast to a solution in which a lower rail 18 is mounted essentially in the middle, an increased force must be applied in order to erect the lower rail 18. This is supported by the lever mechanism 38, which, similar to the principle of a toggle lever, transfers the lower rail 18 into the horizontal position (and vice versa into the vertical position). A boom 40 or lever arm of the lever mechanism 38 engages in an articulated manner on a central section 42 of the lower rail 18 in order to apply an increased pressure force to erect the lower rail 18 according to the principle of an extended lever arm. The lever mechanism 38 is received in a slide 43, via which the lever mechanism 38 can be moved together with the lower rail 18 along the guide rail 12.

Figuren 4a-d zeigen den Hebelmechanismus 38 jeweils in einer Detailansicht. Figuren 5a-d zeigen Ansichten von dem Hebelmechanismus 38 in einer Abfolge zum Überführen der Unterschiene 18 aus der horizontalen Ausrichtung (siehe Figur 5a) in die im Wesentlichen vertikale Ausrichtung (siehe Figur 5d). Figures 4a-d each show the lever mechanism 38 in a detailed view. Figures 5a-d 12 show views of the lever mechanism 38 in a sequence for moving the bottom rail 18 from the horizontal orientation (see FIG Figure 5a ) into the essentially vertical orientation (see Figure 5d ).

Figuren 6a-g zeigen den zuvor erläuterten Seilantrieb 22 in mehreren Erläuterungsansichten. Wie zuvor erwähnt, dient der Seilantrieb 22 dazu, ein Durchbiegen von einer insbesondere langen Unterschiene zu verhindern (siehe z.B. Figur 1a). Der Seilantrieb 22 enthält eine Walze 44 zum Aufrollen und Abrollen des Seils 20 (siehe Figuren 6a,d). Die Walze 44 dient zur Aufnahme des Seils 20 über ihren Umfang. Hierbei wird das Seil 20 durch eine im Gehäuse 46 des Seilantriebs 22 eingetragene Öffnung 48 geführt. Der Seilantrieb 22 ist dazu in der Lage, das Seil 20 einlagig aufgereiht, d.h. spiralförmig, auf dem Umfang von der Walze 44 entlang einer Längsrichtung hiervon aufzuwickeln bzw. abzuwickeln. Hierzu wird die Walze 44 in der besagten Längsrichtung verschoben. Zur Längsverschiebung ist der Umfang von der Walze 44 mit einem Aussengewinde versehen, welches mit einem Innengewindeabschnitt 50 in Eingriff steht, welcher wiederum statisch mit dem Gehäuse 46 des Seilantriebs 22 fixiert ist bzw. hiermit einstückig ausgebildet ist. Bei der Umdrehung der Walze 44 wird diese somit gewindemässig nach links bzw. nach rechts vorgeschoben. Mit der Umdrehung der Walze 44 wird somit gleichzeitig das Seil 20 auf den Umfang der Walze 44 aufgewickelt bzw. abgewickelt und hierbei ebenso durch die Längsverschiebung der Walze einlagig aufgereiht. Somit wird vermieden, dass das Seil 20 in mehreren Lagen aufgewickelt wird - einhergehend mit einem stetig zunehmenden Durchmesser - wodurch wiederum, bei gleichbleibender Drehzahl, die Geschwindigkeit zunimmt, mit welcher das Seil 20 aufgewickelt wird. Mit anderen Worten, gestattet der Seilantrieb 22 ein Aufwickeln und Abwickeln des Seils 20 mit konstanter Geschwindigkeit, bzw. mit einer Geschwindigkeit, welche stets gleich (synchron) ist mit der Geschwindigkeit von weiteren Aufzugsvorrichtungen (z.B. die innerhalb der Führungsschienen eingerichteten Riemenantriebe (siehe z.B. Figur 1b)). Der Seilantrieb 22 gestattet somit Windungen mit konstantem Durchmesser. Figures 6a-g show the previously explained cable drive 22 in several explanatory views. As mentioned above, the cable drive 22 serves to prevent bending of a particularly long lower rail (see e.g. Figure 1a ). The cable drive 22 contains a roller 44 for rolling up and unrolling the cable 20 (see Figures 6a, d ). The roller 44 serves to receive the rope 20 over its circumference. Here, the cable 20 is guided through an opening 48 registered in the housing 46 of the cable drive 22. The cable drive 22 is capable of winding or unwinding the cable 20 in a single layer, ie in a spiral, on the circumference of the roller 44 along a longitudinal direction thereof. For this purpose, the roller 44 is displaced in said longitudinal direction. For longitudinal displacement, the circumference of the roller 44 is provided with an external thread which engages with an internal thread section 50, which in turn is statically fixed to the housing 46 of the cable drive 22 or is formed in one piece with it. When the roller 44 rotates, it is threadedly advanced to the left or to the right. With the rotation of the roller 44, the rope 20 is thus simultaneously wound or unwound onto the circumference of the roller 44 and, in this case, likewise lined up in a single layer by the longitudinal displacement of the roller. This avoids the rope 20 being wound up in several layers - along with a steadily increasing diameter - which in turn increases the speed at which the rope 20 is wound up while the speed remains the same. In other words, the cable drive 22 allows the cable 20 to be wound up and unwound at a constant speed or at a speed which is always the same (synchronous) with the speed of other elevator devices (e.g. the belt drives set up within the guide rails (see e.g. Figure 1b )). The cable drive 22 thus allows windings with a constant diameter.

Figur 6d veranschaulicht ein Beispiel der Walze 44, welche eine abschnittsweise spiralförmige Seilaufnahme enthält. Hierzu enthält die Walze 44 einen Spiralwicklungsabschnitt 52 mit einem spiralförmig zunehmenden Radius. Hierdurch wird es ermöglicht, dass das Seil 20, ausgehend vom geschlossenen Zustand der Lamellenstore, bei der ersten Windung mit einer geringeren Seilspulgeschwindigkeit aufgewickelt wird. Somit ist durch eine konstruktiv einfache und zuverlässige Massnahme die Möglichkeit geschaffen, dass ein Überlauf minimiert wird. Figure 6d Fig. 10 illustrates an example of the roller 44 which includes a sectionally spiral rope take-up. For this purpose, the roller 44 contains a spiral winding section 52 with a spiral increasing radius. This makes it possible for the rope 20, starting from the closed state of the slatted blinds, to be wound up with a lower rope winding speed during the first turn. A structurally simple and reliable measure thus creates the possibility of minimizing overflow.

Figuren 7a,b veranschaulichen das zuvor erläuterte Prinzip des Seilantriebs 22 in jeweils einer Detailansicht. Hierbei ist die Walze 44 mit dem Spiralwicklungsabschnitt 52 mit spiralförmig zunehmenden Radius ausgebildet. Figures 7a, b illustrate the previously explained principle of the cable drive 22, each in a detailed view. Here, the roller 44 is formed with the spiral winding section 52 with a spiral increasing radius.

Figuren 8a-c veranschaulichen Detailansichten von der Wendeeinrichtung 30' (siehe auch Figur 1b). Die Wendeeinrichtung 30' enthält, wie in der Figur 8b veranschaulicht, eine Umlenkeinrichtung 54, über welche eine Kugelschnur 56 von der Wendeeinrichtung 30' an einem Ende vorteilhafterweise derart umgelenkt werden kann, dass die zwei vertikal und parallel zueinander verlaufenden Abschnitte der umgelenkten Kugelschnur 56 weitestgehend maximal voneinander beabstandet werden. Hierbei wird die Bedienung erleichtert. Figuren 9a-c veranschaulichen das Prinzip der Umlenkung von der Kugelschnur 56 in weiteren Detailansichten. Figures 8a-c illustrate detailed views of the turning device 30 '(see also Figure 1b ). The turning device 30 'contains, as in Figure 8b illustrates a deflection device 54, via which a ball cord 56 from the turning device 30 'to a The end can advantageously be deflected in such a way that the two vertically and mutually parallel sections of the deflected ball cord 56 are spaced apart from one another as far as possible to the maximum. Operation is made easier here. Figures 9a-c illustrate the principle of the deflection of the ball cord 56 in further detailed views.

Die Figuren 10a-d zeigen eine Ausführungsform einer Lamelle, wie sie beispielsweise, aber nicht ausschliesslich, in einer der bisher beschriebenen Lamellenstoren zum Einsatz kommen kann. Die Lamelle 116 ist unterteilt in eine Blendenfläche 120 und eine Oberkannte 130. In Bezug auf den Verlauf der Blendenfläche 120 ist die Oberkannte 130 angewinkelt und kann nach innen gerichtet angekantet bzw. nach innen gerichtet gebördelt sein. Die Oberkante 130 ist gegenüber der Blendenfläche 120 bevorzugt in einem Winkel α von 50° bis 80°, insbesondere von 60° bis 70°, wie beispielsweise α = 66°, abgewinkelt. Die Blendenfläche 120 selbst umfasst drei Abschnitten, einen an die Oberkante 130 angrenzenden ersten Blendenflächenabschnitt 121, einen endständigen dritten, Blendenflächenabschnitt 123 und einen zwischen dem ersten Blendenflächenabschnitt 121 und dem dritten Blendenflächenabschnitt 123 liegenden zweiten Blendenflächenabschnitt 122. Der dritte Blendenflächenabschnitt 123 kann ebenfalls nach innen gerichtet angekantet bzw. nach innen gerichtet gebördelt sein. Die Oberkante 130 umfasst zwei Abschnitten, einen endständigen ersten Oberkantenabschnitt 131 und einen an die Blendenfläche 120 angrenzenden zweiten Oberkantenabschnitt 132. Die Unterteilung der Abschnitte ist gegeben durch Änderungen im Verlauf der Lamelle, insbesondere durch eine Biegung oder Winkelung. Bezeichnet man das Abwinkeln der Oberkante 130 in Bezug auf deren Verlauf relativ zur Blendenfläche 120 als nach innen abgewinkelt, so ist die Unterteilung zwischen drittem und zweitem Blendenflächenabschnitt 123, 122 durch eine Innen-Winkelung gekennzeichnet, die Unterteilung zwischen zweitem und erstem Blendenflächenabschnitt 122, 121 durch eine Aussen-Winkelung gekennzeichnet und der Übergang Blendenfläche 120 zu Oberkante 130, und somit die Unterteilung zwischen erstem Blendenflächenabschnitt 121 und zweitem Oberkantenabschnitt 132, durch eine Innen-Winkelung gekennzeichnet. Erster und zweiter Oberkantenabschnitt 131, 132 hingegen sind wieder durch eine Aussen-Winkelung gekennzeichnet. Innen- und Aussen-Winkelung alternieren also im Verlauf des Lamellenquerschnitts, vom freien Ende der Blendenfläche 120 her mit einer Innen-Winkelung beginnend.The Figures 10a-d show an embodiment of a slat, as it can be used, for example, but not exclusively, in one of the slat blinds described so far. The lamella 116 is subdivided into a diaphragm surface 120 and an upper edge 130. With respect to the course of the diaphragm surface 120, the upper edge 130 is angled and can be canted inwardly or beaded inwardly. The upper edge 130 is preferably angled at an angle α of 50 ° to 80 °, in particular 60 ° to 70 °, such as α = 66 °, for example, with respect to the diaphragm surface 120. The screen surface 120 itself comprises three sections, a first screen surface section 121 adjoining the upper edge 130, a terminal third screen surface section 123 and a second screen surface section 122 lying between the first screen surface section 121 and the third screen surface section 123. The third screen surface section 123 can also be directed inwards be canted or beaded facing inwards. The upper edge 130 comprises two sections, a terminal first upper edge section 131 and one on the second upper edge section 132 adjoining the screen surface 120. The subdivision of the sections is given by changes in the course of the lamella, in particular by a bend or angle. If the angling of the upper edge 130 in relation to its course relative to the panel surface 120 is angled inwards, the subdivision between the third and second panel surface sections 123, 122 is characterized by an inner angle, the division between the second and first panel surface sections 122, 121 characterized by an outer angulation and the transition from the diaphragm surface 120 to the upper edge 130, and thus the subdivision between the first diaphragm surface section 121 and the second upper edge section 132, characterized by an inner angled. On the other hand, the first and second upper edge sections 131, 132 are again characterized by an outer angle. Inner and outer angulation thus alternate in the course of the slat cross-section, starting from the free end of the screen surface 120 with an inner angulation.

In Figur 10b ist das Zusammenspiel dreier, wie in Figur 10a näher beschriebener Lamellen 116, 116', 116'' gezeigt. Zu sehen ist, dass insbesondere der einen S-Abbug bildende Verlauf des ersten und des zweiten Blendenflächenabschnitts 121, 122 der einen Lamelle 116'' Raum schafft zum Aufnehmen des, hier gebördelt dargestellten, Endes des dritten Blendenflächenabschnittes der darüber angeordneten Lamelle 116' (siehe gestrichelt gezeichneter Kreis). So ist für eine optisch ebene Behangfläche gesorgt, welche angedeutet ist durch die vertikal verlaufende, gestrichelte Linie. Weiter dargestellt ist der Bereich 155, in welchem sich bevorzugt Durchbohrungen zum Durchführen von Seilen und/oder Aufzugsbändern befinden. Entscheidend für ein gutes Abdunkeln ist, dass die Durchbohrung der einen Lamelle 116' in geschlossenen Zustand von der Blendenfläche der darüber angeordneten Lamelle 116 abgedeckt ist. Die Linie 160 markiert die Grenze des Überlapps der Lamelle 116 und 116'. Die Durchbohrungen befinden sich bevorzugt auf einer Geraden, insbesondere auf der durch den Drehpunkt 135 festgelegten Drehachse der Lamelle 116'. Der Bereich 155 und der Drehpunkt 135 sind der Übersichtlichkeit halber nur für die Lamelle 116' eingezeichnet.In Figure 10b is the interaction of three, as in Figure 10a Slats 116, 116 ', 116''described in more detail are shown. It can be seen that, in particular, the course of the first and second diaphragm surface sections 121, 122 of one lamella 116 ″, which forms an S-bend, creates space for receiving the end of the third diaphragm surface section of the lamella 116 'arranged above it, which is shown here flanged (see Fig dashed circle). In this way, a visually even curtain surface is provided, which is indicated is indicated by the vertical dashed line. The area 155 is also shown, in which there are preferably through-holes for the passage of ropes and / or elevator tapes. It is crucial for good darkening that the through-hole of one lamella 116 ′ is covered in the closed state by the screen surface of the lamella 116 arranged above it. The line 160 marks the limit of the overlap of the lamella 116 and 116 '. The through bores are preferably located on a straight line, in particular on the axis of rotation of the lamella 116 ′ defined by the pivot point 135. For the sake of clarity, the area 155 and the pivot point 135 are only shown for the lamella 116 '.

In Figur 10c zu sehen ist eine Lamelle 116 in unterschiedlichen Ansichten. Die unterste Ansicht zeigt einen Querschnitt der Lamelle 116 in geschlossener und somit im Wesentlichen vertikaler Position, die mittlere Ansicht zeigt einen Querschnitt der Lamelle 116 in offener und somit im Wesentlichen horizontaler Position, und die obere Ansicht zeigt eine Draufsicht auf die Lamelle 116. In der Draufsicht gut zu erkennen ist der seitlich vorragende Führungszapfen 134, dessen Zylinderachse den Drehpunkt 135 bildet. Eingezeichnet in die Figur 10c sind diverse Abstände, wie beispielsweise die Tiefe t der Lamelle, die Distanz X1 der horizontalen Lamelle vom Drehpunkt 135 der Lamelle zum Ende des vorragenden Abschnitts 125 der Blendenfläche 120, der mit der Führungsschiene in Anlage gebracht werden kann, die Distanz X2 der vertikalen Lamelle vom Drehpunkt 135 der Lamelle zum Ende des vorragenden Abschnitts 125 der Blendenfläche 120, und die Distanz X3 vom Ende der Lamelle bis zum Ende des vorragenden Abschnitts 125 der Blendenfläche 120. Die Distanzen X1 und X2 liegen beispielsweise in einem Bereich von 10 bis 20 mm, wie z.B. 14 mm, die Breite b liegt beispielsweise in einem Bereich von 60 bis 80 mm, wie z.B. 69 mm.In Figure 10c a lamella 116 can be seen in different views. The bottom view shows a cross section of the lamella 116 in the closed and thus essentially vertical position, the middle view shows a cross section of the lamella 116 in the open and thus essentially horizontal position, and the upper view shows a top view of the lamella 116 The laterally protruding guide pin 134, the cylinder axis of which forms the pivot point 135, can be clearly seen from above. Drawn in the Figure 10c are various distances, such as the depth t of the slat, the distance X1 of the horizontal slat from the pivot point 135 of the slat to the end of the protruding section 125 of the panel surface 120, which can be brought into contact with the guide rail, the distance X2 of the vertical slat from the point of rotation 135 of the lamella to the end of the protruding section 125 of the diaphragm surface 120, and the distance X3 from the end of the lamella to the end of the protruding section 125 of the diaphragm surface 120. The distances X1 and X2 are, for example, in a range from 10 to 20 mm, such as 14 mm, for example, the width b is in a range from 60 to 80 mm, such as 69 mm.

Der vorragende Abschnitt 125 kann sowohl mit einer Führungsschiene in Anlage gebracht werden als auch mit der Führungsschiene überlappen. Ein Überlappen wird z.B. ermöglicht, indem die Breite bA des vorragenden Abschnitts 125 so gewählt wird, dass diese Breite bA zumindest teilweise den im montierten Zustand von einer Führungsschiene aufgenommen Teil 1341 des Führungszapfens 134 überragt, z.B. um die Breite bz.The protruding section 125 can both be brought into abutment with a guide rail and also overlap with the guide rail. Overlapping is made possible, for example, in that the width b A of the protruding section 125 is selected so that this width b A at least partially protrudes beyond the part 1341 of the guide pin 134, which is received by a guide rail in the assembled state, for example by the width b z .

Figur 10d zeigt zwei Ansichten einer Lamelle 116. Bei der oberen Ansicht handelt es sich um einen Querschnitt, bei der unteren Ansicht um eine Draufsicht. Diese untere Ansicht dient insbesondere dazu, um zu veranschaulichen, wo sich welcher anhand des Querschnitts gezeigte Blendenflächenabschnitt 121, 122, 123 und Oberkantenabschnitt 131, 132 in der Draufsicht auf die Lamelle wiederfindet. Weiter zu erkennen ist, wo im Querschnitt der Lamelle sich der vorragende Abschnitt 125 der Blendenfläche 120 befindet, der mit der Führungsschiene in Anlage gebracht werden kann. Setzt man z.B. die Figuren 10b und 10d miteinander im Bezug, so erkennt man, dass der dritte Blendenflächenabschnitt 123 einer Lamelle 116 so auf einer darunter angeordneten Lamelle 116' zum Liegen kommt, dass ein erster Bereich des vorragenden Abschnitt 125 der Lamelle 116' ebenfalls abgedeckt wird. Zur besseren Kenntlichmachung wurde die Linie 160, welche die Grenze des Überlappens der Lamelle 116 und 116' andeutet, auch in die Figur 10d übertragen. Figure 10d shows two views of a lamella 116. The upper view is a cross section, the lower view is a plan view. This lower view serves in particular to illustrate where the diaphragm surface section 121, 122, 123 and upper edge section 131, 132 shown on the basis of the cross-section can be found in the top view of the lamella. It can also be seen where in the cross section of the lamella the protruding section 125 of the screen surface 120 is located, which can be brought into contact with the guide rail. If you put the Figures 10b and 10d in relation to one another, it can be seen that the third panel surface section 123 of a lamella 116 comes to rest on a lamella 116 'arranged below it that a first area of the protruding portion 125 of the lamella 116 'is also covered. For better identification, the line 160, which indicates the limit of the overlapping of the lamella 116 and 116 ', was also included in the Figure 10d transfer.

Zusammenfassend kann die in den Figuren 10a-d dargestellte Lamelle beschrieben werden als eine Lamelle 116, welche eine abschliessende Blendenfläche 120 und eine hierzu im oberen Abschnitt angewinkelte Oberkante 130 aufweist. Die abschliessende Blendenfläche 120 ragt derart über die abgewinkelte Oberkante 130 seitlich vor, dass der vorragende Abschnitt (125) der Blendenfläche (120) mit Führungsschienen in Anlage bringbar ist und mit seitlichen Führungsschienen überlappbar ist. Die Lamelle ist in einen ersten Blendenflächenabschnitt 121, einen zweiten Blendenflächenabschnitt 122, einen dritten Blendenflächenabschnitt 123, einen ersten Oberkantenabschnitt 131 und einen zweiten Oberkantenabschnitt 132 unterteilt, insbesondere durch Winkelungen, insbesondere durch alternierende Innen-Winkelungen und Aussen-Winkelungen. In summary, the Figures 10a-d The lamella shown are described as a lamella 116 which has a closing panel surface 120 and an upper edge 130 angled in the upper section for this purpose. The closing screen surface 120 protrudes laterally over the angled upper edge 130 in such a way that the protruding section (125) of the screen surface (120) can be brought into contact with guide rails and can be overlapped with lateral guide rails. The lamella is divided into a first panel surface section 121, a second panel surface section 122, a third panel surface section 123, a first upper edge section 131 and a second upper edge section 132, in particular by angles, in particular by alternating inside angles and outside angles.
