Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft ein Lamellensystem nach dem Oberbegriff des Anspruchs 1 sowie ein Kastenmöbel, welches ein solches Lamellensystem aufweist.The invention relates to a lamellar system according to the preamble of claim 1 and to a piece of furniture which has such a lamellar system.

STAND DER TECHNIKSTATE OF THE ART

Es ist bekannt, insbesondere Kastenmöbel mit Türen zu versehen, die aus Lamellen zusammengesetzt sind. Da gibt es zum einen die klassische Lamellenjalousie, bei der eine Matte aus miteinander verbundenen Lamellen in einem Möbelkorpus geführt wird. Weiterhin hat sich in der Vergangenheit auch ein Lamellensystem etabliert, bei welchem die klassische Jalousiematte durch eine Anordnung aus parallel zueinander geführten Lamellen, die mit einer an den Stirnseiten der Lamellen angeordneten Getriebeanordnung bewegt werden, ersetzt wird. Letztere Anordnung hat insbesondere den optischen Vorteil, dass die gesamte Lamellentür im Grunde genommen vor dem Möbelkorpus angeordnet werden kann. Es gehen also keine Räume im Innern des Möbelkorpus für die Unterbringung von Lamellen im geöffneten Zustand verloren. Zum Verbringen des Lamellensystems in die Öffnungsstellung bzw. in die Schließstellung wird ein Antriebsmotor verwendet, der die zumeist als Scherengetriebe ausgebildete Getriebeanordnung betätigt. US 9,637 966 B1 beschreibt eine Lamellenjalousie nach dem Oberbegriff des Anspruchs 1.It is known to provide cabinet furniture in particular with doors that are composed of slats. On the one hand, there is the classic slat blind, in which a mat made of interconnected slats is guided in a furniture body. Furthermore, a slat system has also been established in the past in which the classic blind mat is replaced by an arrangement of slats guided parallel to one another, which are moved with a gear arrangement arranged on the end faces of the slats. The latter arrangement has the particular optical advantage that the entire louvre door can basically be arranged in front of the furniture body. So there are no spaces in the interior of the furniture body for the accommodation of slats lost in the open state. To move the lamella system into the open position or into the closed position, a drive motor is used which has the gear arrangement, which is usually designed as a scissor gear actuated. US 9,637,966 B1 describes a venetian blind according to the preamble of claim 1.

DIE ERFINDUNGTHE INVENTION

Aufgabe der vorliegenden Erfindung ist es, das Lamellensystem der eingangs genannten Art weiterzuentwickeln und ein Kastenmöbel zu schaffen, bei dem auf motorische Antriebe verzichtet werden kann.The object of the present invention is to further develop the slat system of the type mentioned at the outset and to create a cabinet in which motor drives can be dispensed with.

Gelöst wird diese Aufgabe durch ein Lamellensystem mit dem Merkmal des Anspruchs 1. Weiter wird die Aufgabe gelöst durch ein Kastenmöbel mit den Merkmalen des Anspruchs 13. Vorteilhafte Ausführungsformen finden sich in den jeweiligen Unteransprüchen.This object is achieved by a slat system with the feature of claim 1. The object is also achieved by a cabinet with the features of claim 13. Advantageous embodiments can be found in the respective subclaims.

Das erfindungsgemäße Lamellensystem weist einen Lamellenbehang, welcher eine Mehrzahl Lamellen umfasst, sowie eine Verschiebevorrichtung zum Verschieben der Lamellen auf. Die Mehrzahl Lamellen ist dabei miteinander gekoppelt, so dass sie sich mittels der Verschiebevorrichtung von einer Schließstellung, in der die Breitseiten der Lamellen im Wesentlichen in einer zu einer Öffnungs- und Schließrichtung parallelen Ebene flächenbündig liegen und Schmalseiten benachbarter Lamellen einander zugewandt sind, durch Verschieben der Lamellen in der Öffnungs- und Schließrichtung in eine Öffnungsstellung bewegen lassen. In der Öffnungsstellung liegen die Breitseiten der, insbesondere jeder der, Lamellen - insbesondere parallel zueinander aber - nicht parallel zur Öffnungs- und Schließrichtung. Die Verschiebevorrichtung umfasst wenigstens ein Zugmittel, welches an einem Ende mit dem Lamellenbehang gekoppelt ist. Die Lamellen können grundsätzlich aus jedem beliebigen Material sein, bevorzugt sind Glas oder Kunststoff als Material.The slat system according to the invention has a slat curtain which comprises a plurality of slats, as well as a displacement device for moving the slats. The plurality of slats are coupled to one another, so that they move by means of the displacement device from a closed position in which the broad sides of the slats are essentially flush in a plane parallel to an opening and closing direction and the narrow sides of adjacent slats face each other by moving the Let the slats move into an open position in the opening and closing direction. In the open position, the broad sides of the, in particular each of the, slats - in particular parallel to one another but not parallel to the opening and closing direction. The sliding device comprises at least one traction device which is coupled at one end to the slat curtain. The lamellas can in principle be made of any material, preferably glass or plastic as the material.

Erfindungsgemäß umfasst das Lamellensystem weiter wenigstens eine um eine Achse in zwei Richtungen drehbar gelagerte Seilscheibe. An dieser ist das Zugmittel mit seinem anderen Ende befestigt. An der Seilscheibe ist wenigstens ein Arretiermittel angeordnet, welches dazu ausgelegt ist, die Drehung der Seilscheibe in der Öffnungsstellung zu blockieren.According to the invention, the lamella system further comprises at least one pulley mounted rotatably about an axis in two directions. The traction means is attached to this at its other end. At least one locking means is arranged on the pulley and is designed to block the rotation of the pulley in the open position.

Auf diese Weise wird erreicht, dass der Lamellenbehang aus der Schließstellung in die Öffnungsstellung überführt und dort in der Öffnungsstellung fixiert werden kann, ohne dass es eines elektrischen Antriebsmotors mit Selbsthemmung oder dergleichen bedarf.In this way it is achieved that the slat curtain can be transferred from the closed position into the open position and can be fixed there in the open position without the need for an electric drive motor with self-locking or the like.

Zur Arretierung des Lamellenbehanges in der geöffneten Stellung und/oder in Schließstellung ist vorgesehen, dass das wenigstens eine Arretiermittel einen Magneten und/oder ein magnetisierbares, insbesondere ferromagnetisches, Material umfasst. Die magnetische Variante hat den Vorteil, dass zum einen eine Arretierung bewegungslos möglich ist, sodass diese Form der Arretierung auch bei häufigem Öffnen und Schließen des Lamellensystems nicht verschleißt.
Um das erfindungsgemäße Lamellensystem noch flexibler zu gestalten, kann das Arretiermittel an der Seilscheibe in seiner Lage, insbesondere durch eine in der Seilscheibe vorgesehene Kulissenführung, verstellbar und insbesondere fixierbar ausgebildet sein. Auf diese Weise lässt sich eine Feinjustierung des genauen Haltepunktes in der Öffnungsstellung bzw. der Schließstellung der Lamellen vornehmen.To lock the slat curtain in the open position and / or in the closed position, it is provided that the at least one locking means comprises a magnet and / or a magnetizable, in particular ferromagnetic, material. The magnetic variant has the advantage that, on the one hand, locking is possible without moving, so that this form of locking does not wear out even with frequent opening and closing of the lamella system.
In order to make the lamellar system according to the invention even more flexible, the locking means on the pulley in its position, in particular by means of a link guide provided in the pulley, can be designed to be adjustable and, in particular, fixable. In this way, a fine adjustment of the exact stopping point in the open position or the closed position of the slats can be carried out.

Das erfindungsgemäße Lamellensystem kann nach einer besonderen Ausführungsform wenigstens ein erstes Zugmittel und ein zweites Zugmittel umfassen. Die beiden Zugmittel sind dann bevorzugt jeweils mit ihrem einen Ende mit dem Lamellenbehang gekoppelt.According to a particular embodiment, the lamella system according to the invention can comprise at least a first traction means and a second traction means. The two traction means are then preferably each coupled to the slat curtain at one end.

Bei dieser Ausführungsform mit zwei Zugmitteln kann insbesondere auch vorgesehen sein, dass jedem Zugmittel eine Seilscheibe zugeordnet wird. So ist bevorzugt vorgesehen, dass das erfindungsgemäße Lamellensystem in dieser Ausführungsform zusätzlich eine, um eine Achse in zwei Richtungen drehbar gelagerte, zweite Seilscheibe umfasst, wobei das erste Zugmittel mit seinem anderen Ende an der ersten Seilscheibe und das zweite Zugmittel mit seinem anderen Ende an der zweiten Seilscheibe befestigt ist. Mit zwei Seilscheiben lassen sich insbesondere schwerere Behänge vorteilhaft bewegen. In diesem Fall kann auch bei der Arretierung der Seilscheiben in der geöffneten Stellung eine Arretierung gewählt werden, bei der sich die beiden Seilscheiben gegenseitig in der Öffnungsstellung festhalten. Nach einer besonderen Ausführungsform der vorliegenden Erfindung kann daher vorgesehen sein, dass an jeder Seilscheibe wenigstens ein, insbesondere magnetisches oder magnetisierbares, Arretiermittel angeordnet ist, welche dazu ausgelegt sind, die relative Drehung der Seilscheiben in der Öffnungsstellung zu blockieren.In this embodiment with two traction means, it can also be provided in particular that a rope pulley is assigned to each traction means. So it is preferably provided that the lamella system according to the invention in this embodiment additionally comprises a second pulley rotatably mounted about an axis in two directions, the first traction means with its other end on the first rope pulley and the second traction means with its other end on the second pulley is attached. Heavy hangings in particular can be moved advantageously with two pulleys. In this case, when locking the pulleys in the open position, a lock can also be selected in which the two pulleys hold each other in the open position. According to a particular embodiment of the present invention, it can therefore be provided that at least one, in particular magnetic or magnetizable, locking means is arranged on each sheave, which are designed to to block the relative rotation of the pulleys in the open position.

Nach einer bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass das eine Ende des wenigstens einen Zugmittels - bevorzugt können aus Symmetriegründen zwei Zugmittel an beiden seitlichen Bereichen des Lamellenbehangs vorgesehen sein - mit einem mit dem Lamellenbehang gekoppelten Verschiebeelement verbunden ist. Dieses Verschiebeelement kann beispielsweise geführt sein, wobei dies nicht zwingend der Fall sein muss. Das Ende des Zugmittels kann auch alternativ direkt mit dem Lamellenbehang verbunden sein. Nach einer bevorzugten Ausführungsform ist vorgesehen, dass das Verschiebeelement als Mitnehmer ausgebildet ist, der den Lamellenbehang an geeigneter Stelle erfasst und mitzieht.According to a preferred embodiment of the present invention it is provided that one end of the at least one traction means - preferably two traction means can be provided on both lateral areas of the slat curtain for reasons of symmetry - is connected to a displacement element coupled to the slat curtain. This displacement element can be guided, for example, although this does not necessarily have to be the case. Alternatively, the end of the traction means can also be connected directly to the slat curtain. According to a preferred embodiment, it is provided that the sliding element is designed as a driver that grips and pulls the slat curtain at a suitable point.

Bevorzugt ist vorgesehen, dass die Lamellen durch ein Scherengetriebe miteinander gekoppelt sind. Bei der Ausbildung mit Scherengetriebe kann insbesondere vorgesehen sein, dass die Lamellen an parallel zueinander geführten Hebeln des Scherengetriebes angeordneten, zu einer Vorderseite des Lamellenbehangs vorstehenden Hebelfortsätzen angebracht sind. Auf diese Weise kann eine gute Zwangsführung der einzelnen Lamellen erreicht werden. Zudem genügt es hier, wenn das Zugmittel lediglich an einem Teil des Scherengetriebes angreift. Beispielsweise kann das Verschiebeelement mit dem Scherengetriebe gekoppelt, d.h. fest verbunden oder in Kontakt sein. Beispielsweise kann das Zugmittel in Verbindung mit dem Verschiebeelement unter dem untersten Hebel der Schere angeordnet sein und beim Bewegen in die Öffnungsstellung den untersten Hebel der Schere mitziehen. Eine lose Kopplung hat den Vorteil, dass der Lamellenbehang zu Wartungszwecken ausgebaut werden kann, ohne die gesamte Verschiebemimik ausbauen zu müssen.It is preferably provided that the lamellae are coupled to one another by a scissor gear. In the embodiment with a scissor gear, it can be provided in particular that the lamellae are attached to levers of the scissors gear that are arranged parallel to one another and protrude towards a front side of the lamella curtain. In this way, good forced guidance of the individual slats can be achieved. In addition, it is sufficient here if the traction device only engages part of the scissors gear. For example, the displacement element can be coupled to the scissors gear, that is to say firmly connected or in contact. For example, the traction means in connection with the sliding element under the lowest lever of the Be arranged scissors and pull the lowest lever of the scissors when moving into the open position. A loose coupling has the advantage that the slat curtain can be removed for maintenance purposes without having to remove the entire sliding mechanism.

Weiter kann vorgesehen sein, dass die Seilscheibe mit einem Vorspannelement, insbesondere einer Spiralfeder, gekoppelt ist. Dieses Vorspannelement kann insbesondere so ausgebildet sein, dass der Lamellenbehang so vorgespannt ist, dass das Vorspannelement das Bewegen der Lamellen in die Öffnungsstellung unterstützt. Auf diese Weise wird es für eine Bedienperson wesentlich einfacher, ein Kastenmöbel mit dem erfindungsgemäßen Lamellensystem manuell zu öffnen.It can further be provided that the rope pulley is coupled to a pretensioning element, in particular a spiral spring. This pretensioning element can in particular be designed in such a way that the slat curtain is pretensioned in such a way that the pretensioning element supports the movement of the slats into the open position. In this way it becomes much easier for an operator to manually open a cabinet with the slat system according to the invention.

Die Erfindung betrifft mithin auch ein Kastenmöbel, welches einen Möbelkorpus und eine frontseitige Öffnung und ein oben beschriebenes Lamellensystem umfasst. Dabei sind die Lamellen des Lamellensystems so an dem Kastenmöbel angeordnet, dass sie im geschlossenen Zustand die Öffnung des Kastenmöbels verschließen.The invention therefore also relates to a cabinet unit which comprises a furniture body and a front opening and a lamella system as described above. The slats of the slat system are arranged on the cabinet furniture in such a way that they close the opening of the cabinet furniture when it is closed.

An dem erfindungsgemäßen Kastenmöbel kann insbesondere vorgesehen sein, dass mit dem wenigstens einen Arretiermittel der Seilscheibe ein weiteres, mit dem Arretiermittel der Seilscheibe zum Herstellen einer Lagefixierung des Lamellenbehangs zusammenwirkendes Arretiergegenelement am Möbelkorpus angebracht ist. Die Seilscheibe ist bevorzugt am Möbelkorpus, insbesondere am Oberboden desselben, drehbar gelagert. Das genannte Arretiergegenelement kann nach einer bevorzugten Ausführungsform, insbesondere an einem Oberboden des Kastenmöbels angebracht sein. Das Arretiergegenelement kann - wie auch das Arretiermittel an der Seilscheibe - einen Magneten und/oder magnetisierbares, insbesondere ferromagnetisches, Material umfassen, so dass die Arretierung durch magnetische Wechselwirkung bewirkt wird. Natürlich können weitere Arretiermittel an der Seilscheibe oder Arretiergegenelemente am Möbelkorpus, insbesondere einem Oberboden, vorgesehen sein, insbesondere, wenn die Fixierung des Lamellenbehangs in der Schließstellung und/oder in einer Zwischenstellung gewünscht ist.On the cabinet furniture according to the invention it can in particular be provided that with the at least one locking means of the pulley a further counter-locking element cooperating with the locking means of the pulley to fix the position of the slat curtain is attached to the furniture body. The pulley is preferably rotatably mounted on the furniture body, in particular on the top of the same. Said locking counter element can after a Preferred embodiment, in particular be attached to a top panel of the cabinet. The counter-locking element can - like the locking means on the pulley - comprise a magnet and / or magnetizable, in particular ferromagnetic, material, so that the locking is effected by magnetic interaction. Of course, further locking means can be provided on the pulley or counter-locking elements on the furniture body, in particular a top panel, in particular if it is desired to fix the slat curtain in the closed position and / or in an intermediate position.

Nach einer bevorzugten erfindungsgemäßen Ausführungsform des Kastenmöbels ist der Lamellenbehang, insbesondere über ein oder zwei Scherengetriebe, an einer oder den beiden die Öffnung begrenzenden Seitenwänden in einem Führungsbereich des Möbelkorpus geführt. Der Führungsbereich kann dabei so vorgesehen sein, dass dieser sich in die Seitenwände des Möbelkorpus einsetzen lässt. Auf diese Weise kann eine sehr kompakte Führungsmimik für den Lamellenbehang zur Verfügung gestellt werden.According to a preferred embodiment of the cabinet furniture according to the invention, the slat curtain is guided, in particular via one or two scissor gears, on one or both of the side walls delimiting the opening in a guide area of the furniture body. The guide area can be provided so that it can be inserted into the side walls of the furniture body. In this way, a very compact guide mechanism for the slat curtain can be made available.

Auch kann vorgesehen sein, dass das oben beschriebene Verschiebeelement in wenigstens einer sich parallel zur Öffnungs- und Schließrichtung erstreckenden Führung in Öffnungs- und Schließrichtung verschieblich geführt ist. Diese Führung kann ebenso in dem Führungsbereich liegen, in dem auch der Lamellenbehang geführt ist.It can also be provided that the displacement element described above is guided displaceably in at least one guide extending parallel to the opening and closing direction in the opening and closing direction. This guide can also be located in the guide area in which the slat curtain is also guided.

Die oben beschriebene Technik mit der wenigstens einen Seilscheibe kann bei besonders schweren Behängen, z. B. bei hohen Schränken, genutzt werden, um zusätzlich einen Antriebsmotor anzubringen. Dabei kann vorgesehen sein, dass die wenigstens eine Seilscheibe an einem auf dem Oberboden befestigten Drehlager gelagert ist. Das Drehlager weist dabei einen Motoranschlussflansch auf, an welchem ein Antriebsmotor befestigt ist. Dabei ist die Motorwelle mit der Seilscheibe gekoppelt, so dass der Motor die Seilscheibe drehend antreiben kann. Auf diese Weise wird die Drehung der Motorwelle auf die Seilscheibe übertragen und es können aufgrund der so entstehenden Drehmomente auch größere Kräfte auf das oder die Zugmittel und somit auf den Behang übertragen werden. Zudem kann der Antrieb einfach ausgetauscht werden, ohne dass das übrige Lamellensystem oder die übrige Antriebsmimik demontiert werden muss. Auf diese Weise erhält man eine besonders wartungsfreundliche Konstruktion.The technique described above with the at least one pulley can be used for particularly heavy hangings, for. B. in tall cabinets, can be used to attach a drive motor. It can be provided that the at least one pulley is mounted on a pivot bearing attached to the top panel. The pivot bearing has a motor connection flange to which a drive motor is attached. The motor shaft is coupled to the pulley so that the motor can drive the pulley to rotate. In this way, the rotation of the motor shaft is transmitted to the sheave and, due to the torques that arise in this way, greater forces can also be transmitted to the traction device (s) and thus to the curtain. In addition, the drive can easily be exchanged without having to dismantle the rest of the lamella system or the rest of the drive mechanism. In this way, a particularly maintenance-friendly construction is obtained.

Die hier verwendeten Seilscheiben können Durchmesser aufweisen, die im Bereich der Korpustiefe des Kastenmöbels liegen.The pulleys used here can have diameters that are in the range of the body depth of the cabinet.

Vorteilhafterweise kann vorgesehen sein, dass die Drehachse der Motorwelle parallel zur Drehachse der Seilscheibe verläuft, insbesondere mit dieser identisch ist.It can advantageously be provided that the axis of rotation of the motor shaft runs parallel to the axis of rotation of the pulley, in particular is identical to it.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST WAY TO CARRY OUT THE INVENTION

Das in den Figuren 1 - 4 näher dargestellte Kastenmöbel 10 ist als Korpusmöbel aufgebaut und weist als solches Seitenwände 11, 13, eine Rückwand 12, einen Oberboden 14, welcher noch durch eine Abdeckung abgedeckt werden kann, einen Unterboden 15 und an der Frontseite eine Öffnung 16 auf, durch welche das Innere des Kastenmöbels 10 zugänglich ist.That in the Figures 1 - 4 Box furniture 10 shown in more detail is constructed as a body furniture and as such has side walls 11, 13, a rear wall 12, an upper floor 14, which can still be covered by a cover, a lower floor 15 and on the front side an opening 16 through which the interior of the box furniture 10 is accessible.

Das Kastenmöbel 10 ist mit einem erfindungsgemäßen Lamellensystem 20 ausgestattet, bei welchem ein Behang aus Lamellen 21 die Öffnung 16 verschließt. Das Lamellensystem lässt sich in einer Öffnungs- und Schließrichtung X öffnen bzw. schließen. Die Breitseiten 21a der Lamellen 21 liegen in der in Figur 1 gezeigten Schließstellung flächenbündig nebeneinander in einer Ebene. Dabei liegen die in der Zeichnung breiteren Schmalseiten 21b benachbarter Lamellen 21 einander gegenüber. Mit 21c sind die an der Stirnseite der Lamellen 21 im Bereich der Seitenwangen oder Seitenwände 11 und 13 liegenden Schmalseiten der Lamellen 21 bezeichnet.The cabinet furniture 10 is equipped with a slat system 20 according to the invention, in which a curtain made of slats 21 closes the opening 16. The lamella system can be opened and closed in an opening and closing direction X. The broad sides 21a of the slats 21 are in the Figure 1 shown closed position flush next to each other in one plane. The narrow sides 21b of adjacent slats 21, which are wider in the drawing, lie opposite one another. The narrow sides of the lamellae 21 lying on the end face of the lamellae 21 in the region of the side cheeks or side walls 11 and 13 are denoted by 21c.

Die miteinander gekoppelten Lamellen 21 sind über wenigstens ein Zugmittel 22a und 22b, bei welchem es sich bevorzugt um ein Zugseil oder Zugband handelt, mit einer in zwei Richtungen P1, P2 drehbar gelagerten Seilscheibe 23 gekoppelt, wobei das oder die Zugmittel 22a und 22b über die Schmalseite der Seilscheibe 23 geführt ist/sind. Durch Anheben des Behangs aus Lamellen 21, beispielsweise durch Angreifen an einen (hier nicht gezeigten) Griff im unteren Bereich des Kastenmöbels 10 können die in Figur 1 in der Schließstellung gezeigten Lamellen 21 in Richtung X in die in Figur 2 gezeigte Öffnungsstellung bewegt werden. Bei diesem Vorgang dreht sich die Seilscheibe 23 um die Drehachse A in Richtung des Pfeils P1. Umgekehrt dreht sich die am Oberboden 14 gelagerte Seilscheibe 23 um die Drehachse A in Richtung des Pfeils P2, wenn die Lamellen 21 aus der in Figur 2 gezeigten Stellung in die in Figur 1 gezeigte Stellung zurückgeführt werden. In beiden geschilderten Fällen wird eine Zwischenstellung durchlaufen, wie sie in Figur 3 gezeigt ist.The lamellas 21, which are coupled to one another, are coupled via at least one traction means 22a and 22b, which is preferably a traction rope or tension band, to a rope pulley 23 rotatably mounted in two directions P1, P2, with the traction means 22a and 22b via The narrow side of the pulley 23 is guided / are. By lifting the hanging made of slats 21, for example by grasping a handle (not shown here) in the lower region of the cabinet 10, the in Figure 1 in the closed position lamellae 21 in the direction X in the Figure 2 Open position shown are moved. During this process, the pulley 23 rotates about the axis of rotation A in the direction of the arrow P1. Conversely, the rope pulley 23 mounted on the top floor 14 rotates about the axis of rotation A in the direction of the arrow P2 when the slats 21 move out of the position shown in FIG Figure 2 position shown in Figure 1 position shown are returned. In both cases described, an intermediate position is passed through, as shown in Figure 3 is shown.

Mit Bezug auf die Figuren 4 und 5 wird die Ankopplung des Zugmittels 22a, 22b an die Seilscheibe 23 und die Arretierung der Seilscheibe 23 näher erläutert. In Figur 4 ist dazu eine Stellung gezeigt, die weitgehend der Öffnungsstellung von Figur 2 entspricht. Im gezeigten Beispiel ist das Zugmittel 22a über eine Umlenkrolle 27 geführt und mit einem Ende in dem Bereich 28a an der Seilscheibe 23 befestigt. In der Seilscheibe 23 kann eine Kulisse 29a oder allgemein eine Verstelleinrichtung angebracht sein, sodass der Befestigungspunkt 28a sich noch in radialer Richtung verstellen lässt. Dies hat den Vorteil, dass eine Feinanpassung der Länge des Zugmittels 22a möglich ist. Ähnliches gilt entsprechend für das bevorzugt vorgesehene weitere Zugmittel 22b hinsichtlich des Befestigungspunktes 28b und der Kulisse 29b.With reference to the Figures 4 and 5 the coupling of the traction means 22a, 22b to the pulley 23 and the locking of the pulley 23 are explained in more detail. In Figure 4 a position is shown that is largely the open position of Figure 2 corresponds. In the example shown, the traction means 22a is guided over a deflection roller 27 and fastened with one end in the area 28a to the pulley 23. A link 29a or generally an adjusting device can be attached in the pulley 23, so that the fastening point 28a can still be adjusted in the radial direction. This has the advantage that a fine adjustment of the length of the traction means 22a is possible. The same applies accordingly to the preferably provided further traction means 22b with regard to the fastening point 28b and the link 29b.

Zumindest in der Öffnungsstellung sollte der aus den Lamellen 21 gebildete Behang nicht von selbst infolge der Schwerkraft in die Schließstellung zurückkehren. Hierzu ist eine Arretierung vorgesehen, die zumindest in der Öffnungsstellung die Seilscheibe 23 gegenüber dem Oberboden 14 des Kastenmöbels 10 arretiert. Dazu ist am Oberboden ein Magnet 24 oder zumindest ein magnetisches Material fixiert. An der Seilscheibe 23 findet sich ein entsprechendes Gegenelement 25, welches entweder magnetisch oder zumindest magnetisierbar ist. Auch andere Arretierungen sind natürlich möglich. Wird also der Behang aus Lamellen 21 geöffnet, gelangt die Seilscheibe mit dem Element 25 in den Wirkbereich des Magneten 24, sodass zwischen diesen beiden Elementen 24, 25 eine gegenseitige magnetische Anziehung bewirkt wird, welche die Seilscheibe 23 dort festhält und gegenüber dem Oberboden 14 arretiert, wo die magnetische Wechselwirkung am größten ist. Zur Feinjustierung kann hier ebenfalls in Umfangsrichtung an der Seilscheibe 23 eine Verstellkulisse 25a oder allgemein eine Verstelleinrichtung zur Verstellung des Elements 25 an der Seilscheibe 23 vorgesehen sein.At least in the open position, the curtain formed from the slats 21 should not return to the closed position by itself as a result of gravity. For this purpose, a locking device is provided which, at least in the open position, locks the pulley 23 relative to the top panel 14 of the cabinet 10. For this purpose, a magnet 24 or at least a magnetic material is fixed on the top floor. On the pulley 23 there is a corresponding counter element 25 which is either magnetic or at least magnetizable. Of course, other locks are also possible. If the curtain made of slats 21 is opened, the pulley with element 25 comes into the effective area of magnet 24, so that a mutual magnetic attraction is brought about between these two elements 24, 25, which holds pulley 23 there and locks it against top panel 14 where the magnetic interaction is greatest. For fine adjustment, an adjusting link 25a or generally an adjusting device for adjusting the element 25 on the sheave 23 can also be provided on the sheave 23 in the circumferential direction.

Soll der Behang aus Lamellen 21 aus der Öffnungsstellung wieder in die Schließstellung überführt werden, wird der Benutzer an dem Behang aus Lamellen 21 ziehen (beispielsweise über einen schon angesprochenen Griff), und dadurch die Arretierung durch Überwinden der Magnetkraft oder einer sonstigen durch die Arretierung ausgeübten Kraft oder durch Entsperren eines Riegels oder dergleichen lösen. Der Behang kann dann durch eine Bedienperson wieder in die geschlossene Stellung zurückgezogen werden.If the curtain made of slats 21 is to be moved from the open position back into the closed position, the user will pull on the curtain made of slats 21 (for example using a handle already mentioned) and thereby lock the device by overcoming the magnetic force or something else Loosen force or by unlocking a bolt or the like. The curtain can then be pulled back into the closed position by an operator.

Hierzu kann es sich als nützlich erweisen, wenn ein Vorspannelement eingesetzt wird, welches auf die Seilscheibe 23 eine Vorspannung ausübt. Diese ist bevorzugt so gehalten, dass eine Vorspannung aufgebaut wird, wenn der Behang in die Schließstellung zurückkehrt. Dies hat den Vorteil, dass zum einen die Abwärtsbewegung des Behangs aus Lamellen 21 gebremst oder gedämpft wird, sodass der Behang in der Schließstellung z.B. nicht an einem Anschlag hart anschlägt. Zum anderen kann diese Vorspannung dazu verwendet werden, beim Öffnen des Behangs die ansonsten gegen die Schwerkraft aufzubringende Muskelkraft der betätigenden Person zu unterstützen. Bevorzugt ist dazu vorgesehen, dass eine um die Drehachse A herum gelegte, im Bereich der Drehscheibe 23 angeordnete Spiralfeder als Vorspannelement eingesetzt wird. Natürlich sind auch andere Vorspannelemente grundsätzlich möglich.For this purpose, it can prove to be useful if a prestressing element is used which exerts a prestress on the pulley 23. This is preferably held in such a way that a pretension is built up when the curtain returns to the closed position. This has the advantage that, on the one hand, the downward movement of the curtain made of slats 21 is braked or dampened so that the curtain does not hit a stop in the closed position, for example. On the other hand, this pretension can be used to support the muscle force of the person operating the device, which otherwise has to be applied against gravity, when the curtain is opened. For this purpose, it is preferably provided that a spiral spring placed around the axis of rotation A and arranged in the area of the rotary disk 23 is used as a preloading element. Of course, other pretensioning elements are also possible in principle.

Während das eine Ende des Zugmittels 22a, 22b an der Seilscheibe 23 befestigt ist, greift das andere Ende des Zugmittels an dem Lamellensystem 20 an, um dieses beim Öffnen anzuheben bzw. beim Schließen zu bremsen. Dabei kann das Zugmittel direkt mit den Lamellen 21 oder deren Antriebsvorrichtung 30 verbunden sein. Im in Figur 5 gezeigten Beispiel umfasst das Antriebssystem 30 der Lamellen ein Scherengetriebe, wobei - wie in Figur 6 gezeigt - dieses Scherengetriebe aus einer Mehrzahl miteinander gelenkig verbundener Hebel 31, 32, 34 gebildet sein kann, wobei die parallel zueinander angeordneten Hebel 31 einen zur Vorderseite 35 weisenden Fortsatz 33 aufweisen, an welchem die Lamellen 21 befestigt sind.While one end of the traction mechanism 22a, 22b is attached to the pulley 23, the other end of the traction mechanism engages the lamellar system 20 in order to raise it when opening or to brake it when closing. The traction means can be connected directly to the slats 21 or their drive device 30. In the in Figure 5 In the example shown, the drive system 30 of the slats comprises a scissor gear, wherein - as in FIG Figure 6 shown - this scissors mechanism can be formed from a plurality of levers 31, 32, 34 articulated to one another, the levers 31 arranged parallel to one another having an extension 33 facing the front 35 to which the lamellae 21 are attached.

In Figur 5 ist ein Führungsbereich 40 an der Seitenwand 13 (ein entsprechender Führungsbereich kann auch an der gegenüberliegenden Seitenwand 11 vorgesehen sein) abgebildet, in welchem das Scherengetriebe 30 geführt oder jedenfalls untergebracht ist. Am in der Zeichnung unteren Ende des Scherengetriebes 30 ist ein Verschiebeelement 42 vorgesehen, welches mit dem Ende des entsprechenden Zugmittels 22a bzw. 22b fest verbunden ist oder in Kontakt steht. Dieses Verschiebeelement 42 liegt im gezeigten Beispiel gegen die Unterseite des Scherengetriebes 30 an. Wird also die Seilscheibe so bewegt, dass sich der Behang aus Lamellen 21 öffnet, drückt das Verschiebeelement 42 gegen das Scherengetriebe und schiebt dieses zusammen, sodass man die in Figur 5 dargestellte Situation erhält. Das Verschiebeelement 42 ist bevorzugt in einer Führung 41 im Bereich 40 geführt. Wird die Arretierung in der Öffnungsstellung gelöst und der Behang wieder in Richtung der geschlossenen Stellung gezogen, schiebt sich die Schere 30 auseinander und schiebt das Verschiebeelement 42 in Richtung X nach unten, bis die Schließstellung erreicht ist. Wenn die Seilscheibe 23 vorgespannt ist, wird das Verschiebeelement 42 durch die sich aufbauende Vorspannung im Verlauf des Schließvorgangs abgebremst, da es über ein Zugmittel mit der Seilscheibe verbunden ist. Je nach Auslegung der Vorspannung kann das Schließen des Behangs durch die Schwerkraft des Behangs unterstützt werden. Bei geeigneter Ausführung des Vorspannelements kann auch erreicht werden, dass der Schließvorgang eine Selbsthemmung aufweist, sodass der Behang in jeder beliebigen Stellung zwischen der Öffnungsstellung und der Schließstellung verharren kann.In Figure 5 a guide area 40 is shown on the side wall 13 (a corresponding guide area can also be provided on the opposite side wall 11) in which the scissors gear 30 is guided or at least accommodated. At the lower end of the scissors gear 30 in the drawing, a displacement element 42 is provided, which is firmly connected or in contact with the end of the corresponding traction means 22a or 22b. In the example shown, this displacement element 42 rests against the underside of the scissors gear 30. If the pulley is moved in such a way that the curtain made of slats 21 opens, the sliding element 42 presses against the scissor gear and pushes it together so that the situation shown in FIG. 5 is obtained. The displacement element 42 is preferably guided in a guide 41 in the area 40. If the lock is released in the open position and the curtain is pulled back in the direction of the closed position, the scissors 30 pushes apart and pushes the sliding element 42 downward in the direction X until the closed position is reached. When the sheave 23 is pretensioned, the displacement element 42 is braked by the pretension that builds up in the course of the closing process, since it is connected to the sheave via a traction means. Depending on the design of the bias, the closing of the curtain can be supported by the gravity of the curtain. With a suitable design of the prestressing element, it can also be achieved that the closing process has a self-locking so that the curtain can remain in any position between the open position and the closed position.

Auf diese Weise lässt sich ein entsprechender Behang aus Lamellen 21 mit einem relativ einfachen System manuell aus einer Öffnungsstellung in eine Schließstellung und umgekehrt bewegen. Wird ein Vorspannelement verwendet, ist diese Art der Verstellung auch komfortabel und kann den Behang aus Lamellen 21 vor Beschädigungen schützen.In this way, a corresponding curtain made of slats 21 can be moved manually from an open position into a closed position and vice versa with a relatively simple system. If a pretensioning element is used, this type of adjustment is also convenient and can protect the curtain made of slats 21 from damage.

Das in Figur 7 dargestellte Ausführungsbeispiel unterscheidet sich von dem vorher diskutierten Ausführungsbeispiel lediglich darin, dass nicht nur eine Seilscheibe 23', sondern eine weitere Seilscheibe 23" am Oberboden 14 des Kastenmöbels 10 gelagert ist. Jede der Seilscheiben 23', 23" ist dann mit einem Ende eines Zugmittels verbunden, dessen anderes Ende jeweils mit dem Behang aus Lamellen 21 gekoppelt ist, beispielsweise so wie oben beschrieben. In dieser Ausführungsform gibt es also zwei Seitenscheiben und zwei Zugmittel. Die Zugmittel sind dann an beiden Seitenwänden 13 bzw. 11 des Möbels 10, zum Beispiel in der oben beschriebenen Weise, geführt. Zwar ist auch hier möglich, dass die beiden Seilscheiben entsprechend über Arretierungsmittel gegenüber dem Oberboden 14 in der Öffnungsstellung arretiert werden. In dieser Ausführungsform ist jedoch bevorzugt vorgesehen, dass die beiden Seilscheiben 23', 23" in der geöffneten Stellung sich gegenseitig festhalten. Dies wird erreicht, indem eine magnetische Wechselwirkung zwischen den beiden Seilscheiben 23', 23" hervorgerufen wird. Bevorzugt werden dazu magnetische bzw. magnetisierungsbare Elemente 25', 25" im radial äußeren Bereich der Seilscheiben vorgesehen, die sich jeweils an einer Position befinden, sodass sie sich im geöffneten Zustand des Möbels 10 gegenüber liegen und einander magnetisch anziehen können.This in Figure 7 The illustrated embodiment differs from the previously discussed embodiment only in that not only one pulley 23 ', but a further pulley 23 "is mounted on the top 14 of the cabinet 10. Each of the pulleys 23', 23" then has one end of a traction device connected, the other end of which is coupled to the curtain made of slats 21, for example as described above. In this embodiment there are two side windows and two traction means. The traction means are then guided on both side walls 13 and 11 of the piece of furniture 10, for example in the manner described above. It is also possible here for the two pulleys to be locked in the open position with respect to the top panel 14 using locking means. In this embodiment, however, it is preferably provided that the two pulleys 23 ', 23 "hold each other tightly in the open position. This is achieved by causing a magnetic interaction between the two pulleys 23', 23". For this purpose, magnetic or magnetizable elements 25 ′, 25 ″ are preferably provided in the radially outer region of the pulleys, which are each located in a position so that they are in the open state of the Furniture 10 are opposite and can attract each other magnetically.

Zur Unterstützung bzw. Arretierung des Behangs in der Schließstellung kann bei allen Ausführungsformen vorgesehen sein, dass im oder am Boden 16 ein Magnet angeordnet ist und zumindest die letzte, d. h. unterste bzw. dem Boden 16 in der Schließstellung am nächsten liegende Lamelle des Behangs ein magnetisches oder magnetisierungsbares Bauteil aufweist. In der Schließstellung wird so erreicht, dass aufgrund der magnetischen Wechselwirkung zwischen Boden 16 des Kastenmöbels 10 und der letzten Lamelle diese an den Boden 16 herangezogen wird.
