Description

Die Erfindung betrifft ein Möbel mit einer Bremsvorrichtung für Jalousiezüge und dergleichen translatorisch bewegbarer und/oder aufrollbarer Roll- oder Schiebeelemente, wobei die Möbel kastenförmig ausgebildet sind und einander gegenüberliegende Korpusseiten aufweisen, wobei die Jalousiezüge, die aus nebeneinander angeordneten Profilen, Stäben, Leisten und dergleichen bestehen, beweglich in in den einander gegenüberliegenden Korpusseiten eingebrachten Nuten bzw. Führungselementen geführt sind und einem Bremskörper.The invention relates to a piece of furniture with a braking device for blinds and the like translationally movable and / or rollable rolling or sliding elements, wherein the furniture are box-shaped and have opposing cabinet sides, the blinds consisting of juxtaposed profiles, bars, strips and the like exist, are movably guided in introduced in the opposite carcass sides grooves or guide elements and a brake body.

Derartige Jalousiezüge werden in Einrichtungsgegenständen, insbesondere von Möbeln, eingesetzt, wobei diese auch als Rollschränke bezeichnet werden. Rollschränke haben den Vorteil, dass sie hinsichtlich des Platzbedarfes sehr vorteilhaft sind. Sie nehmen den gleichen Platz bzw. Volumen in Anspruch, unabhängig davon, ob sie geöffnet oder geschlossen sind. Derartige Rollschränke sind im Allgemeinen so ausgeführt, dass an den vertikalen oder auch horizontalen Korpusseiten Nuten ausgebildet sind, in denen sich die Jalousiezüge bewegen können und zwar derart, dass sie sich vorzugsweise auf- bzw. abwärts bewegen. Die Jalousiezüge aus dem bekannten Stand der Technik werden üblicherweise aus Profilen, Stäben, Leisten oder Ähnlichem gebildet, wobei diese beispielsweise rückseitig an einem einheitlichen Stoff oder an einer ähnlichen Bahn befestigt sind oder aber auch über Verbindungselemente miteinander direkt verbindbar sind.Such blinds are used in furnishings, especially furniture, which are also referred to as rolling cabinets. Rolling cabinets have the advantage that they are very advantageous in terms of space requirements. They occupy the same space or volume, regardless of whether they are open or closed. Such roller cabinets are generally designed so that on the vertical or horizontal carcass sides grooves are formed in which the blind pulls can move in such a way that they preferably move up or down. The blinds of the prior art are usually formed from profiles, bars, strips or the like, which are for example attached to the back of a uniform material or on a similar path or can be connected to one another directly via connecting elements.

Jalousiezüge und die mit ihnen korrespondierenden Nuten bzw. Führungselemente müssen so ausgebildet sein, dass zum einen die Nuten bzw. Führungselemente so breit ausgeführt sind, dass die Jalousiezüge darin leicht und ohne Kraftaufwand bewegbar sind. Andererseits dürfen die Jalousiezüge in den Nuten bzw. Führungselementen nicht zu leicht bewegbar sein, da diese sonst beispielsweise bei der Abwärtsbewegung auf die Finger des Nutzers fallen können und so zu Verletzungen führen.Venetian blinds and the corresponding with them grooves or guide elements must be designed so that on the one hand, the grooves or guide elements are made so wide that the blinds are easily and effortlessly moved therein. On the other hand, the blind pulls must not be too easy to move in the grooves or guide elements, as they can otherwise fall, for example, in the downward movement of the user's fingers and thus lead to injury.

Jalousiezüge haben beispielweise bei Rollschränken, in denen die Bewegung vertikal erfolgt, den Nachteil, dass diese sich beim Öffnen bzw. Schließen ungebremst bewegen können, wodurch beim Benutzer ein gewisses Verletzungsrisiko entstehen kann.Roller blinds, for example, have the disadvantage that they can move unrestricted when opening or closing, where the user a certain risk of injury may arise in rolling cabinets in which the movement is vertical.

Die DE 12 37 748 zeigt ein Bremssystem für einen Rollladen eines Schrankes, bei dem auf der Rückseite zwei Federn angeordnet sind. Die Federn sind mit einem Ende und gegenüberliegend im Bereich von Seitenflächen des Schrankes angelenkt, wobei das jeweilig andere Ende in einem an dem Schlussbalken des Rollladens befestigten Ring eingehängt ist. Sowohl beim Schließen wie auch Öffnen des Rollladens wird die Bewegung des Rollladens durch die beiden Federn abgebremst.
Durch die Anlenkung der Federn auf der Rückseite ist die Bestimmung des Bremspunktes, zumindest beim Verschließen des Rollladens, problematisch, da die Federn, wie in Figur 3 der Zeichnung dargestellt, an der hinteren oberen Kante des Schrankes abgeknickt werden. Die einzelnen Windungen der Spiralen der Federn verhaken sich somit beim Verschließen des Rollladens und insbesondere kurz vor der Endstellung des Rollladens können die durch das Verhaken erzeugten Kräfte je nach Geschwindigkeit der Bewegung des Rollladens unterschiedlich groß sein, so dass mal die eine, mal die andere Windung der Spiralen den Rollladen zum Halten bringt und somit unterschiedliche Haltepunkte definiert. Durch die permanente Verbindung von Ring und Spiralen ist die dargestellte Bremsvorrichtung auch denkbar ungeeignet für die durch die vorliegende Erfindung ebenfalls beanspruchte schneckenförmige Führungsschiene.The DE 12 37 748 shows a brake system for a shutter of a cabinet, in which two springs are arranged on the back. The springs are articulated at one end and opposite in the region of side surfaces of the cabinet, wherein the respective other end is suspended in a ring attached to the closing bar of the shutter. Both when closing and opening the shutter, the movement of the shutter is slowed down by the two springs.
Due to the articulation of the springs on the back of the determination of the braking point, at least when closing the shutter, problematic because the springs, as shown in Figure 3 of the drawing, are bent at the rear upper edge of the cabinet. The individual turns of the spirals of the springs thus get caught when closing the shutter and especially shortly before the final position of the shutter, the forces generated by the hooking can be different depending on the speed of movement of the shutter, so that sometimes the one, sometimes the other turn The spirals brings the shutter to a halt and thus defines different breakpoints. Due to the permanent connection of the ring and spirals, the brake device shown is also conceivable unsuitable for the also claimed by the present invention helical guide rail.

Die US 3,532,153 zeigt einen Rollladenschrank mit einem Bremssystem im oberen Bereich des Schrankes. Im Bereich der beiden Enden eines Profils des Rollladens sind federnde Elemente fest angelenkt, die gemäß einem Ausführungsbeispiel der Erfindung mit einem anderen Federelement, das an der Rückseite des Schrankes angelenkt ist, verbunden sind. Diese Verbindung bewirkt eine Bremsbewegung, jeweils beim Öffnen und Schließen des Rollladens. Vorteilhaft gegenüber der DE 12 37 748 ist die Befestigung des federnden Elementes an der Rückseite im oberen Bereich, so dass die Bremsvorrichtung nicht über eine Kante abgeknickt wird. Durch die permanente Verbindung der Bremsvorrichtung mit dem Rollladen ist auch dieses System für ein schneckenförmiges Aufrollen des Rollladens ungeeignet.The US 3,532,153 shows a roller shutter cabinet with a brake system in the upper part of the cabinet. In the region of the two ends of a profile of the shutter resilient elements are firmly articulated, which are connected according to an embodiment of the invention with another spring element which is hinged to the back of the cabinet. This connection causes a braking movement, respectively when opening and closing the shutter. Advantageous over the DE 12 37 748 is the attachment of the resilient element at the rear in the upper region, so that the braking device is not bent over an edge. Due to the permanent connection of the braking device with the roller shutter and this system is unsuitable for a helical rolling of the shutter.

Die US 4,657,318 betrifft ebenfalls einen Rollladenschrank mit Bremssystem. Das Bremssystem ist innerhalb des Schrankes unter einer Ebene des Rollladens im oberen Bereich des Schrankes angeordnet. Dabei weisen die jeweiligen Endprofile des Rollladens Haken auf, die in über die Breite des Schrankes gespannte federnde Elemente einhaken.The US 4,657,318 also relates to a roller shutter cabinet with brake system. The braking system is located within the cabinet below a level of the shutter in the upper area of the cabinet. In this case, the respective end profiles of the shutter on hooks that hook in over the width of the cabinet stretched resilient elements.

Die zweifache Ausführung von federnden Elementen dient dem Abbremsen beim Öffnen bzw. Schließen des Rollladens aufgrund der zu geringen Tiefe des Schrankes und damit die federnden Elemente nicht umgelenkt werden müssen. Im Falle nur eines federnden Elementes würde sich nämlich entweder beim Schließen oder Öffnen des Rollladens das federnde Element quer durch den Innenraum des Schrankes erstrecken, sofern nicht eine Umlenkung im Bereich der Umlenkung des Rollladens vorgesehen ist.The double execution of resilient elements is used to slow down when opening or closing the shutter due to the low depth of the cabinet and thus the resilient elements must not be diverted. In the case of only one resilient element, namely, either the spring element would extend transversely through the interior of the cabinet when closing or opening the shutter, unless a deflection in the region of the deflection of the shutter is provided.

Bei der DE 298 16 832 U1 wird ein Rollladensystem beschrieben, das ein Federmechanismus auf der Rückseite eines Rollladenschrankes aufweist. Vornehmlich wird dieses Federsystem aber nicht zum Abbremsen des Rollladens verwendet, sondern es dient der leichtgängigen Betätigung des Rollladens selbst. Im Übrigen geht diese Vorrichtung nicht über den Stand der Technik der anderen zitierten Schriften hinaus.In the DE 298 16 832 U1 a roller shutter system is described which has a spring mechanism on the back of a roller shutter cabinet. Notably, this spring system is not used to slow down the shutter, but it is the smooth operation of the shutter itself. Incidentally, this device does not go beyond the prior art of the other cited scriptures.

Die DE 296 18 802 U1 zeigt als einzige Schrift eine schneckenförmige Führungsschiene für den Rollladen. Im Gegensatz zur erfindungsgemäßen Lösung ist aber ein Seil für einen Gewichtsausgleich des Rollladens an der vordersten Profilschiene, zumindest im vorderen Bereich des Rollladens, angelenkt. Dieses System kann durchaus als Bremssystem verstanden werden, wobei aber im Falle der schneckenförmigen Führungsschiene dieses System nicht mit denen aus den anderen zitierten Schriften mit fester Anlenkung des Bremssystems an dem Rollladen kombinierbar ist. Es erscheint nämlich nicht zweckmäßig, vielmehr ist es auch technisch unvorteilhaft, wenn das federnde Element, das im Bereich de hinteren Endes des Rollladens mit diesem fest verbunden ist, mit dem Rollladen im geöffneten Zustand des jeweiligen Schrankes aufgerollt würde.The DE 296 18 802 U1 shows as the only font a helical guide rail for the roller shutter. In contrast to the solution according to the invention but a rope for weight balance of the shutter on the front rail, at least in the front of the shutter, hinged. This system can certainly be understood as a braking system, but in the case of the helical guide rail this system can not be combined with those from the other cited documents with fixed articulation of the brake system on the roller shutter. It does not appear appropriate, but it is also technically unfavorable if the resilient element which is firmly connected in the area de rear end of the shutter with this, would be rolled up with the shutter in the open state of the respective cabinet.

Um diese Nachteile zu beseitigen, ist bereits vorgeschlagen worden, im hinteren Teil von Schrank und Jalousiezug ein Federsystem einzubringen. Mit diesem Federsystem kann erreicht werden, dass der Jalousiezug leicht in der Nut bzw. Führungselement bewegbar ist, ohne sich von selbst zu bewegen, wenn der Nutzer diesen nicht mehr berührt. Der Nachteil dieser Lösung besteht darin, dass einerseits das Federsystem sehr kompliziert aufgebaut und damit sehr aufwändig montierbar ist und andererseits das nutzbare Volumen des Schrankes reduziert wird, da eine zusätzliche Rückwand erforderlich ist, hinter der dieses Federsystem befestigt werden muss.
Eine weitere Möglichkeit besteht darin, die Nuten bzw. Führungselemente relativ breit auszuführen, um die Beweglichkeit der Jalousiezüge zu gewährleisten, aber in der Nut bzw. dem Führungselement einen zusätzlichen Stoff einzubringen, wie z.B. einen Kunststoffstreifen, der die Bewegung der Jalousiezüge bremsen soll.
Es wurde weiterhin vorgeschlagen, an bestimmten Profilen, Stäben, Leisten und dergleichen der Jalousiezüge Reibungszapfen anzubringen, die in den Nuten bzw. Führungselementen mitlaufen und die Bewegung der Jalousiezüge bremsen.
In der Funktionsfähigkeit und auch in der Wirtschaftlichkeit dieser Lösungen treten jedoch erhebliche Nachteile und Probleme auf.To eliminate these disadvantages, it has already been proposed to introduce a spring system in the rear part of the cabinet and blind pull. With this spring system can be achieved that the blind pull easily in the groove or guide element is movable without moving by itself, if the user does not touch it. The disadvantage of this solution is that on the one hand the spring system is constructed very complicated and thus very expensive to assemble and on the other hand, the usable volume of the cabinet is reduced because an additional rear wall is required behind which this spring system must be attached.
Another possibility is to make the grooves or guide elements relatively wide in order to ensure the mobility of the blind pulls, but to introduce an additional material in the groove or the guide element, such as a plastic strip which is to slow the movement of the blind pulls.
It has also been proposed to attach to certain profiles, rods, strips and the like of the blind pulls friction pins that run in the grooves or guide elements and slow down the movement of the blind pulls.
In the functionality and also in the economy of these solutions, however, there are significant disadvantages and problems.

Bremsvorrichtungen für Jalousiezüge der eingangs beschriebenen Art bestehen herkömmlicherweise aus an den Enden von Jalousiezügen befestigten Seilzügen, die ihrerseits mit einem eine Drehfeder und einen Arretierkörper aufweisenden Feststelloder Bremskörper verbunden sind, der sich vorzugsweise im Inneren des Schrankes im hinteren Bereich quer durch diesen erstreckt.
Diese Bremsvorrichtungen sind jedoch bei Reparaturen nur sehr schwer und umständlich zugänglich, so dass am Möbel selbst erhebliche Vorarbeiten auszuführen sind, um mögliche defekte Teile der Bremsvorrichtung auszutauschen bzw. diese zu reparieren.Brake devices for blinds of the type described above are conventionally made of cables attached to the ends of blinds cables, which in turn are connected to a torsion spring and a locking body Feststelloder brake body, which preferably extends in the interior of the cabinet in the rear region across it.
However, these braking devices are very difficult and cumbersome to access during repairs, so that the furniture itself is to carry out considerable preliminary work to replace any defective parts of the brake device or to repair them.

Es wurden weiterhin als Bremsvorrichtungen federbelastete Rollen, die auf die Innenseiten der Jalousiezüge wirken, verwendet. Das durch eine Federkraft belastete und sich auf der Innenseite abstützende Element drückt die Außenfläche desJalousiezuges gegen die Außenkante der Nut bzw. des Führungselementes, um so eine die Bewegung der Jalousiezüge entgegenwirkende Reibungskraft zu erzeugen.
Diese Lösung hat jedoch den Nachteil, dass diese Bremsvorrichtung ständig im Eingriff zu den Jalousiezügen steht, so dass das Öffnen oder Schließen nur gegen die Überwindung der entgegenwirkenden Reibungskraft möglich ist. Eine Leichtgängigkeit, welche insbesondere bei sehr hohen Schränken erforderlich ist, ist durch diese Lösung somit nicht gegeben.There were also used as braking devices spring-loaded rollers that act on the inner sides of the blind pulls. The spring-loaded and internally-supporting member presses the outer surface of the blind pull against the outer edge of the groove or guide member so as to create a frictional force counteracting the movement of the blind pulls.
However, this solution has the disadvantage that this braking device is constantly engaged with the blinds, so that the opening or closing is possible only to overcome the counteracting friction force. A smooth running, which is required especially for very high cabinets, is thus not given by this solution.

Eine weitere Bremsvorrichtung, die auf Jalousiezüge wirkt, ist aus der DE 195 31 071 bekannt.
Die hier beschriebene Bremsvorrichtung besteht aus einem in einem Gehäuse angeordneten Bremskörper, wobei der Bremskörper als bewegliche, aus einer in Bremsrichtung arretierenden Bremsbetriebsstellung durch ein mit dem Jalousiezug koppelbarem Betätigungselement in eine Freigabestellung überführbare Bremsbacke, ausgebildet ist. Durch die bewegliche Anordnung des Bremskörpers innerhalb des Gehäuses ist dieser in Folge des Eigengewichtes bei geöffnetem Jalousiezug automatisch in der Bremsstellung positioniert. Wird der Jalousiezug geöffnet, wird die Bremsbacke durch den Betätigungskörper, beispielsweise einem Streifen aus einem elastischen Material, im Verlaufe der Öffnungsbewegung des Jalousiezuges automatisch in seine Freigabestellung überführt, so dass der Jalousiezug ohne Behinderungen durch den Bremskörper selbst in seine geöffnete Stellung gebracht werden kann. Derartige Bremsvorrichtungen sind jedoch konstruktiv sehr aufwändig herstellbar bzw. montierbar und dadurch entsprechend kostenintensiv. Ein weiterer Nachteil wird darin gesehen, dass es durch den an der Innenseite des Jalousiezuges reibenden Bremskörper zu optischen Beeinträchtigungen bzw. zu Schädigungen des Jalousiezuges führen kann.Another braking device that acts on blind pulls is out of the DE 195 31 071 known.
The brake device described here consists of a brake body arranged in a housing, wherein the brake body is designed as a movable, from a brake operating position arresting in the braking direction by a can be coupled to the blind pull actuator operable in a release position brake shoe. Due to the movable arrangement of the brake body within the housing this is automatically positioned in the braking position as a result of its own weight with the blinds open. If the blind pull open, the brake shoe is automatically transferred by the actuator body, such as a strip of an elastic material in the course of the opening movement of the blind pull in its release position, so that the blind pull can be brought without hindrance by the brake body itself in its open position. However, such braking devices are structurally very complex to produce or assemble and thus correspondingly expensive. Another disadvantage is seen in the fact that it can lead to visual impairment or damage to the blind pull by rubbing on the inside of the blind train braking body.

Der vorliegenden Erfindung liegt somit die Aufgabe zu Grunde, eine Bremsvorrichtung für Jalousiezüge zu schaffen, mit der die erläuterten, mit dem bekannten Stand der Technik verbundenen Nachteile beseitigt werden können, die mit einfachen baulichen Mittel hergestellt bzw. montiert werden kann und die einen geringen Kostenaufwand verursacht.The present invention is therefore based on the object to provide a braking device for blinds, with the explained, associated with the known prior art disadvantages can be eliminated with simple structural Means can be manufactured or assembled and which causes a low cost.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Weitere vorteilhafte Ausgestaltungen sind den entsprechenden Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in the corresponding subclaims.

In einer vorteilhaften Ausführung des erfindungsgemäßen Möbels mit einer Bremsvorrichtung für Jalousiezüge ist das dehnbare Element als Gummischnur mit an ihren freien Enden angeordneten Befestigungselementen ausgebildet, so dass diese vorteilhafterweise sehr einfach auch an sehr gut zugänglichen Stellen in dem Möbel anbringbar ist.In an advantageous embodiment of the furniture according to the invention with a braking device for blinds the stretchable element is designed as a rubber cord with arranged at their free ends fasteners so that it is advantageously very easy to attach even in very accessible places in the furniture.

Das verwendete Halteelement, welches wenigstens einen von seiner Grundfläche wegragenden bogenförmigen Haken aufweist, ist an dem Profil, Stab, Leiste oder dergleichen des Jalousiezuges angeordnet, welches bei durch den Jalousiezug geschlossenem Möbel der oberen Korpusseite beabstandet zugeordnet ist.The holding element used, which has at least one projecting from its base arcuate hook is disposed on the profile, bar, bar or the like of the blind pull, which is associated with spaced by the blind pull furniture of the upper cabinet side spaced.

Es konnte weiterhin überraschend festgestellt werden, dass an den Aufnahmeelementen, welche eine schneckenförmig ausgebildete Führungsschiene aufweisen, Befestigungselemente für das dehnbare Element anordenbar sind, die eine Funktionsfähigkeit der Bremsvorrichtung gewährleisten.It has further been found, surprisingly, that attachment elements for the expandable element can be arranged on the receiving elements, which have a helically formed guide rail, which ensure a functional capability of the braking device.

Die Vorteile des erfindungsgemäßen Möbels mit einer Bremsvorrichtung werden in dem geräuscharmen Bremsvorgang, dem extrem geringen Montageaufwand der Bremsvorrichtung und den geringen Kosten gesehen. Die Bremsvorrichtung für Jalousiezüge ist auf Grund ihrer Dimensionierung sehr platzsparend in den entsprechenden Möbeln integrierbar, und kann auch jederzeit in bereits bestehende Schranksysteme nachträglich montiert werden. Die Bremsvorrichtung kann durch das verwendete dehnbare Element sehr individuell den entsprechenden Schrankbreiten bzw. Schrankhöhen und damit dem Gewicht der Jalousiezüge angepasst werden.
Zur weiteren Erläuterung der Erfindung wird auf die Unteransprüche, die Zeichnungen sowie die nachfolgende Beschreibung verwiesen. In den Zeichnungen sind dargestellt:

Die Fig. 1 zeigt einen Ausschnitt einer Innenansicht eines Rollladenschrankes, in dem der Jalousiezug 8 von seiner Rückseite sichtbar ist. Dieser Schrank kann beispielsweise als Küchenschrank, als Rollschrank unter einem Schreibtisch oder aber als normaler Büroschrank ausgeführt sein. Der Schrank besteht aus einander gegenüberliegenden Korpusseiten 2, von denen nur einer dargestellt ist, eine diese Korpusseiten 2 bedeckende Korpusseite 1 und einen nicht dargestellten Korpusboden. An der Korpusseite 2 sind im oberen Bereich des Schrankes Aufnahmeelemente 3 angebracht, die eine schneckenförmig ausgebildete Führungsschiene 31 aufweisen. Der Jalousiezug 8 wird beim Öffnen durch die Führungsschiene 31 des Aufnahmeelementes 3 kontrolliert geführt. Das Aufnahmeelement 3 kommuniziert mit einer Schiene 4, so dass der Jalousiezug 8 an seinen Seitenteilen komplett durch die Führungsschiene 31 bzw. die Schiene 4 geführt und teilweise abgedeckt ist. In diesem Ausführungsbeispiel ist das Halteelement 6 an dem Profil 9 des Jalousiezuges 8 angeordnet, welches bei durch den Jalousiezug 8 geschlossenem Möbel der Korpusseite 1 beabstandet zugeordnet ist. An der Korpusseite 1 befindet sich eine Bremsvorrichtung, welche in diesem Ausführungsbeispiel als Gummischnur 51 ausgeführt ist. Die Gummischnur 51 weist an ihren freien Enden angeordnete Befestigungselemente 7 auf, die in der Korpusseite 1 befestigbar sind. Die Gummischnur 51 ist zur Korpusseite 1 so beabstandet angeordnet, dass bei einer Bewegung des Jalousiezuges 8 das Halteelement 6 in diese eingreift und die Bewegung desJalousiezuges 8 abbremst. Die Spannung des zwischen den Befestigungselementen 7 angeordneten, als Gummischnur 51 ausgeführten dehnbaren Element 5 ist so gewählt, dass entsprechend der Höhe des Schrankes ein sicheres und unfallfreies Abbremsen des Jalousiezuges 8 jederzeit gewährleistet ist. Bei der Schließbewegung des Jalousiezuges 8 setzt sich dieser nach Überschreiten seines Schwerpunktes in vertikaler Richtung in Bewegung, bis das Haltelement 6 in das als Gummischnur 51 ausgebildete dehnbare Element 5 eingreift, so dass dieses entsprechend dem Gewicht des Jalousiezuges 8 nachgibt und bei optimaler Einstellung der Spannung des als Gummischnur 51 ausgeprägten, dehnbaren Elementes 5 kurz vor dem Verschließen am Korpusboden des Möbels gestoppt wird. Durch ein leichtes Nachdrücken an den am Jalousiezug 8 angebrachten Griffelementen kann dieser nun in eine Schließstellung gebracht werden. Es liegt jedoch auch im Rahmen der Erfindung, dass das dehnbare Element 5 im Bereich der an den Korpusseiten 2 anbringbaren Aufnahmeelemente 3 anbringbar ist. Diese Aufnahmeelemente 3 weisen eine schneckenförmig ausgebildete Führungsschiene 31 auf, in der der Jalousiezug 8 im oberen Bereich der Korpusseiten 2 führbar ist.The Fig. 1 shows a section of an interior view of a roller shutter cabinet in which the blind pull 8 is visible from its back. This cabinet can be designed, for example, as a kitchen cupboard, as a roll-up cupboard under a desk or as a normal office cupboard. The cabinet consists of opposite sides of the cabinet 2, of which only one is shown, these body sides 2 covering body side 1 and a body bottom, not shown. On the body side 2 receiving elements 3 are mounted in the upper region of the cabinet, which have a helical guide rail 31 formed. The blind pull 8 is guided controlled by the guide rail 31 of the receiving element 3 when opening. The receiving element 3 communicates with a rail 4, so that the blind pull 8 is guided at its side parts completely through the guide rail 31 and the rail 4 and partially covered. In this embodiment, the holding element 6 is arranged on the profile 9 of the blind pull 8, which is associated with spaced by the blind pull 8 furniture of the cabinet side 1 spaced. On the body side 1 is a braking device, which is designed in this embodiment as a rubber cord 51. The rubber cord 51 has at its free ends arranged fastening elements 7, which are fastened in the body side 1. The rubber string 51 is arranged so spaced from the body side 1, that during a movement of the blind pull 8, the holding element 6 engages in this and the movement of the blind pull 8 brakes. The voltage of the arranged between the fasteners 7, designed as a rubber belt 51 stretchable element 5 is chosen so that according to the height of the cabinet a safe and accident-free braking of the blind pull 8 is guaranteed at all times. During the closing movement of the blind pull 8, this is after moving its center of gravity in the vertical direction in motion until the holding element 6 engages the trained as a rubber string 51 stretchable element 5, so that this yields according to the weight of the blind pull 8 and optimal setting of the voltage of the rubber belt 51 pronounced, stretchable element 5 is stopped shortly before closing on the body floor of the cabinet. By a slight pressure on the attached to the blind pull 8 handle elements this can now be brought into a closed position. However, it is also within the scope of the invention that the expandable element 5 in the region of attachable to the carcass sides 2 receiving elements 3 can be attached. These receiving elements 3 have a helical guide rail 31, in which the blind pull 8 can be guided in the upper region of the carcass sides 2.

In Figur 2 ist ein Halteelement 6 dargestellt, welches in diesem Ausführungsbeispiel eine annährend ovale Grundfläche 62 aufweist, in die Öffnungen 63 eingebracht sind. Das Halteelement 6 weist wenigstens einen von seiner Grundfläche 62wegragenden bogenförmigen Haken 61 auf, welcher so dimensioniert ist, dass er an dem dehnbaren Element 5 eingreift und den Jalousiezug 8 abbremst. Es liegt jedoch auch im Rahmen der Erfindung, dass das Halteelement 6 zwei von seiner Grundfläche 62 wegragende bogenförmige Haken 61 aufweist, so dass der Jalousiezug 8 sowohl beim Öffnen als auch beim Schließen durch die erfindungsgemäße Bremsvorrichtung abstoppbar ist.In FIG. 2 a holding element 6 is shown, which in this embodiment has an approximately oval base 62, are introduced into the openings 63. The holding element 6 has at least one arc-shaped hook 61 protruding from its base 62, which is dimensioned such that it engages the expandable element 5 and brakes the blind pull 8. It is, however, also in the Frame of the invention that the holding element 6 has two projecting from its base 62 arcuate hook 61, so that the blind pull 8 can be stopped both when opening and when closing by the braking device according to the invention.
