Description

Die Erfindung betrifft eine Bremsvorrichtung für Jalousiezüge oder dergleichen translatorisch bewegbare und/oder aufrollbare Roll- oder Schiebelemente von insbesondere Möbeln, wobei die Jalousiezüge aus nebeneinander angeordneten parallelen und in Querrichtung der Jalousien verlaufenden Stäben, Leisten oder ähnlichen zusammengesetzt und diese an ihren Querkanten in in den einander gegenüberliegenden Seitenwänden ausgeführten Nuten oder ähnlichen Führungsschienen hin und her beweglich geführt sind.The invention relates to a braking device for blinds or the like translationally movable and / or rollable rolling or sliding elements of particular furniture, the blinds consisting of juxtaposed parallel and running in the transverse direction of the blinds bars, strips or the like and composed at their transverse edges in the running opposite side walls executed grooves or similar guide rails are guided back and forth.

Schränke mit Jalousiezügen, auch als Rollschränke bezeichnet, finden heute vielfältig speziell in Büroeinrichtungen Verwendung. Rollschränke haben den Vorteil, dass sie hinsichtlich des Platzbedarfs sehr vorteilhaft sind. Sie nehmen den gleichen Platz in Anspruch unabhängig davon, ob sie geöffnet oder geschlossen sind. Rollschränke sind im allgemeinen so ausgeführt, dass an den vertikalen Schrankseiten Nuten ausgebildet sind, in denen sich die Jalousiezüge bewegen und zwar derart, dass sich die Jalousiezüge vorzugsweise auf- bzw. abwärts bewegen. Die Jalousiezüge werden üblicherweise aus Stäben, Leisten oder Ähnlichem gebildet und können rückseitig an einem einheitlichen Stoff oder einer ähnlichen Bahn befestigt sein.Cabinets with jalousie pulls, also called roll cabinets, are today used in a variety of ways, especially in office facilities. Rolling cabinets have the advantage that they are very advantageous in terms of space requirements. They occupy the same space regardless of whether they are open or closed. Rolling cabinets are generally designed so that on the vertical sides of the cabinet grooves are formed in which move the blinds in such a way that the blinds move preferably up or down. The blinds are usually formed from rods, strips or the like and can be attached to the back of a uniform fabric or similar track.

Jalousiezüge und die mit ihnen korrespondierenden Nuten müssen so ausgebildet sein, dass zum einen die Nuten so breit ausgeführt werden müssen, dass der Jalousiezug darin leicht und ohne großen Kraftaufwand läuft. Zum anderen darf der Jalousiezug in den Nuten nicht zu leicht laufen, da dieser sonst beispielsweise auf die Finger fallen kann und so Verletzungen verursachen kann.Venetian blinds and the corresponding grooves with them must be designed so that on the one hand, the grooves must be made so wide that the blind pull it easily and without much effort. On the other hand, the blind pull must not run too easily in the grooves, because otherwise it can fall on the fingers, for example, and thus cause injuries.

Jalousiezüge haben bei Rollschränken, in denen der Jalousiezug vertikal bewegt wird, d. h. auf- bzw. abwärts, den Nachteil, dass diese sich beim Öffnen oder Schließen ungebremst bewegen, wodurch ein gewisses Verletzungsrisiko beim Benutzer entstehen kann.Roller blinds have in roll cabinets, in which the blind pull is moved vertically, d. H. up or down, the disadvantage that they move unrestrained when opening or closing, which may cause a certain risk of injury to the user.

Um diese Nachteile zu beseitigen, ist bereits vorgeschlagen worden, im hinteren Teil von Jalousiezug und Schrank ein Federsystem unterzubringen.In order to eliminate these disadvantages, it has already been proposed to accommodate a spring system in the rear part of the pull-out pull-pull and closet.

In der EP 1 076152 A1 wird ebenfalls eine gattungsgemäße Bremsvorrichtung beschrieben. Diese Bremsvorrichtung wird für eine Schrankrollladentür eingesetzt, deren seitliche Kanten jeweils in einem Kanal/Führungsschiene geführt sind. Die Bremsvorrichtung ist an beiden Seiten des der Schrankinnenwand an der Führungsschiene/dem Kanal geordnet. Die Bremselemente der Bremsvorrichtung sind jeweils auf einem Hebel exzentrisch angeordnet. Bei Bewegung der Schrankrollladentür nach unten wird die Bremsvorrichtung in Gang gesetzt. Bei dieser Bewegung drückt das Bremselement die seitliche Kante der Schrankrollladentür gegen den Kanal/Führungseinrichtung derart, dass sich die Reibungskraft zwischen beiden wesentlich erhöht und eine Verzögerung der Bewegung hervorruft.In the EP 1 076152 A1 Also a generic brake device is described. This braking device is used for a cupboard door, the side edges are each guided in a channel / guide rail. The brake device is arranged on both sides of the cabinet inner wall on the guide rail / the channel. The brake elements of the brake device are each arranged eccentrically on a lever. When the cupboard door is moved down, the braking device is started. During this movement, the brake element presses the lateral edge of the cabinet roller shutter door against the channel / guide means such that the frictional force between them substantially increases and causes a delay in the movement.

Mit diesem Federsystem wird erreicht, dass der Jalousiezug leicht in der Nut läuft, ohne sich beim Loslassen von selbst zu bewegen. Der Nachteil dieser Lösung besteht darin, dass einerseits das Federsystem sehr kompliziertes aufgebaut und andererseits eine doppelte Rückwand erforderlich ist.This spring system ensures that the blind pulls easily into the groove without moving on release. The disadvantage of this solution is that on the one hand the spring system constructed very complicated and on the other hand, a double rear wall is required.

Eine weitere Möglichkeit besteht darin, die Nuten relativ breit auszuführen, um die Beweglichkeit des Jalousiezuges zu gewährleisten, und in der Nut einen bremsenden Stoff (z.B. Polyurethan) zum Bremsen der Jalousiebewegung anzubringen.
Des weiteren wurde vorgeschlagen, an bestimmten Stäben des Jalousiezuges Reibungszapfen anzubringen, die in den Nuten laufen und die Jalousiebewegung bremsen.
In der Funktionsfähigkeit dieser Möglichkeiten traten jedoch Nachteile und Probleme auf.Another possibility is to make the grooves relatively wide, to ensure the mobility of the blind pull, and to install in the groove a braking material (eg polyurethane) for braking the blind movement.
Furthermore, it has been proposed to attach friction pins to certain bars of the blind pull, which run in the grooves and slow down the movement of the blind.
However, in the functioning of these possibilities, disadvantages and problems arose.

Bremsvorrichtungen der eingangs beschrieben Art bestehen herkömmlicherweise aus an den Enden von Jalousiezügen befestigten Seilzügen, die ihrerseits mit einem eine Drehfeder und einen Arretierkörper aufweisenden Feststell- oder Bremskörper verbunden sind, der sich vorzugsweise im Schrankinneren im hinteren Bereich quer durch das Möbel erstreckt.
Diese sind bei Reparaturen nur sehr schwer zugänglich, so dass am Möbel selbst erhebliche Arbeiten auszuführen sind, um defekte Teile der Bremseinrichtung auszutauschen oder diese zu reparieren.Brake devices of the type described above are conventionally made of cables attached to the ends of blind trains, which in turn are connected to a torsion spring and a locking body having locking or braking body, which preferably extends in the cabinet interior in the rear area across the furniture.
These are very difficult to access in case of repairs, so that considerable work has to be carried out on the furniture itself in order to replace defective parts of the brake device or to repair them.

Weiterhin werden als Bremsvorrichtungen federbelastete Rollen, die auf die Innenseite des Jalousiezuges wirken, verwendet. Das durch eine Federkraft belastete und sich auf der Innenseite abstützende Element drückt die Außenfläche des Jalousiezuges gegen die Außenkante der Nut oder einer ähnlichen Führungsschiene, um so die der Bewegung des Jalousiezuges entgegen wirkende Reibungskraft zu erhöhen.
Diese Lösung hat den Nachteil, dass die Bremseinrichtung ständig im Eingriff steht, so dass das Öffnen oder Schließen nur gegen Überwindung der entgegenwirkenden Reibungskraft möglich ist. Eine Leichtgängigkeit ist somit nicht gegeben.Furthermore, as a braking devices spring-loaded rollers that act on the inside of the blind pull used. The loaded by a spring force and on the inside supporting element presses the outer surface of the blind pull against the outer edge of the groove or a similar guide rail, so as to increase the movement of the blind pull counteracting frictional force.
This solution has the disadvantage that the braking device is constantly engaged, so that the opening or closing is possible only to overcome the counteracting friction force. A smooth running is therefore not given.

Eine Bremsvorrichtung, die auf den Jalousiezug wirkt, ist aus der DE 195 31 071 C1 bekannt.A braking device that acts on the shutter pull is out of the DE 195 31 071 C1 known.

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 koppelbaren 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 gelegen. Wird der Jalousiezug geöffnet, wird die Bremsbacke durch den Betätigungskörper, z.B. einen Streifen aus einem elastischen Material im Verlaufe der Öffnungsbewegung des Jalousiezuges automatisch in seine Freigabestellung überführt, so dass der Jalousiezug ohne irgendwelche Behinderungen durch den Bremskörper selbst in seine geöffnete Stellung gebracht werden kann.The braking device described here consists of a brake body arranged in a housing, wherein the brake body is designed as a movable, from a locking in the braking direction brake operating position by an engageable with the blind pull actuator in a release position convertible brake shoe. Due to the movable arrangement of the brake body within the housing, it is automatically located in the braking position as a result of its own weight when the blind pull is open. When the blind pull is opened, the brake shoe is moved by the operating body, e.g. a strip of an elastic material in the course of the opening movement of the blind train automatically transferred to its release position, so that the blind pull can be brought without any hindrance by the brake body itself in its open position.

Derartige Bremseinrichtungen sind konstruktiv sehr aufwendig und dadurch bedingt auch teuer. Darüber hinaus kann es durch den an der Innenseite des Jalousiezuges reibenden Bremskörpers zu Zerstörungen der Jalousiezüge kommen.Such braking devices are structurally very expensive and therefore also expensive. In addition, damage to the blind pulls can occur as a result of the brake body rubbing against the inside of the blind pull.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine neue Bremsvorrichtung für Jalousiezüge zu schaffen, mit der die oben erläuterten mit dem bekannten Stand der Technik verbundenen Nachteile beseitigt werden können, und die mit einfachen baulichen Mitteln hergestellt werden kann und einen geringen Kostenaufwand verursacht.The present invention has for its object to provide a new brake device for blind pulls, with which the above-mentioned known disadvantages associated with the known prior art can be eliminated, and which can be produced with simple structural means and causes a low cost.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Bremskörper der Bremsvorrichtung aus wenigstens einer orthogonal zum Jalousiezug angeordneten Rolle besteht, die an ihrem Umfang ein Ringelement aufweist, wobei die Rolle über eine Welle drehbeweglich gelagert und in einer im Grundkörper angeordneten Schlitzführung geführt ist, wobei die Rolle auf die Innenfläche des Jalousiezuges wirkt.According to the invention, the object is achieved in that the brake body of the brake device consists of at least one orthogonal to the blind pull arranged roller having a ring member at its periphery, wherein the roller is rotatably mounted on a shaft and guided in a arranged in the body slit guide, wherein the Roller acts on the inner surface of the blind pull.

Die Schlitzführung ist in zwei miteinander verbundene Führungskulissen aufgeteilt. Die Führungskulissen sind vorteilhafterweise winklig zueinander ausgeführt, wobei die eine Führungskulisse in einem geringeren Winkel zur Längsachse des Grundkörpers angeordnet ist als die andere Führungskulisse. Wesentlich an der Erfindung ist die Schlitzführung, in der die Rolle bewegbar ist.The slot guide is divided into two interconnected guide slots. The guide slots are advantageously carried out at an angle to each other, wherein the one guide slot is arranged at a smaller angle to the longitudinal axis of the base body than the other guide slot. Essential to the invention is the slot guide in which the roller is movable.

Über die Führungskulisse mit dem kleineren Winkel wird die Rolle durch den Jalousiezug in die untere Endlage verfahren. Dadurch verringert sich der Abstand des Rollenpaares zum Jalousiezug.
Der Jalousiezug wird dadurch mit seiner Außenseite gegen die Innenkante der Nut bzw. Führungskulisse gedrückt und somit die Reibungskraft erhöht. Infolge dessen wird der Jalousiezug abgebremst. Bei der entgegengesetzten Bewegung des Jalousiezuges wird die Rolle in die zweite Führungskulisse verfahren. Diese ist wesentlich steiler ausgeführt, so dass die Bremswirkung auf den Jalousiezug aufgehoben wird. Dadurch, dass die Rolle nunmehr in die obere Endlage verfahren wird, ist auch der Druck auf den Jalousiezug aufgehoben. Der Jalousiezug ist wieder leicht bewegbar.
Durch die vorteilhafte Verwendung eines Rollenpaares können Verkantungen bei ihrem Verfahren in die jeweilige Endlage der Schlitzführung vermieden werden.
Die einzelnen Rollen weisen eine Ringnut zur Aufnahme von Ringelementen auf. Die Ringnut kann voll umfänglich oder in Segmenten ausgeformt sein. Mindestens ein Grundkörper mit dem Bremskörper ist im nicht sichtbaren Bereich zwischen einer das Innere der Möbel freigebenden bzw. verschließenden Position des Jalousiezuges angeordnet.About the guide slot with the smaller angle, the roller is moved by the shutter pull in the lower end position. This reduces the distance of the pair of rollers to the blind pull.
The blind pull is thereby pressed with its outer side against the inner edge of the groove or guide slot and thus increases the frictional force. As a result, the blind pull is slowed down. In the opposite movement of the blind pull the roller is moved in the second guide slot. This is designed much steeper, so that the braking effect is canceled on the blind pull. The fact that the role is now moved into the upper end position, the pressure on the blind pull is canceled. The blind pull is again easily movable.
Due to the advantageous use of a pair of rollers tilting can be avoided in their process in the respective end position of the slot guide.
The individual rollers have an annular groove for receiving ring elements. The annular groove can be formed fully circumferentially or in segments. At least one main body with the brake body is arranged in the non-visible region between a position of the blind pull releasing or closing the interior of the furniture.

Die Vorteile der erfindungsgemäßen Bremsvorrichtung sind zum einen in einem geräuscharmen Bremsvorgang, da sich die Rolle mitdreht, und zum anderen in einem geringen Verschleißverhalten, da die Ringelemente, welche beispielsweise aus Silikon bestehen, nicht bleibend verformt werden und ein gutes Rückstellverhalten aufweisen, zu sehen.
Ein weiterer Vorteil ist, dass die Bremsvorrichtung so ausgebildet ist, dass sie sowohl rechts oder links als auch horizontal oder vertikal, insbesondere bei Möbeln, eingesetzt werden kann.The advantages of the braking device according to the invention are on the one hand in a low-noise braking, since the role rotates, and on the other in a low wear behavior, since the ring elements, which consist for example of silicone, are not permanently deformed and have a good recovery behavior to see.
Another advantage is that the braking device is designed so that it can be used both on the right or left as well as horizontally or vertically, especially in furniture.

The arranged parallel to the roller axis fasteners 11, 11 'are designed so that their width is slightly larger than that of the shaft 4 connected to the rollers 2, 2'. The main body 1 is designed so that it can be mounted both left and right inside the cabinet.

Die Fig. 2 zeigt ein Rollenpaar. Dieses besteht aus den beiden Rollen 2, 2', wobei an einer der beiden Rollen 2, 2' eine Welle 4 angeformt ist. Nach dem Durchstecken der Welle 4 durch die Schlitzführung 6 im Grundkörper 1 kann die zweite Rolle 2, 2' aufgesteckt werden. Am äußeren Umfang der Rollen 2, 2' sind die kreisförmig ausgeführten Ringelemente 3, 3' eingebracht. Durch die Verwendung eines Rollenpaares kann dieses bei der Bewegung innerhalb der Schlitzführung 6 des Grundkörpers 1 nicht verkannten. Bei Verwendung einer einzelnen Rolle 2, 2' im Grundkörper 1 kann es zum Verklemmen bzw. zur Schwergängigkeit kommen.The Fig. 2 shows a pair of roles. This consists of the two rollers 2, 2 ', wherein on one of the two rollers 2, 2', a shaft 4 is formed. After inserting the shaft 4 through the slot guide 6 in the base body 1, the second roller 2, 2 'are plugged. On the outer circumference of the rollers 2, 2 ', the circular running ring elements 3, 3' are introduced. By using a pair of rollers this can not be misjudged in the movement within the slot guide 6 of the base body 1. When using a single roller 2, 2 'in the base body 1, it can lead to jamming or stiffness.

Die Fig. 3 zeigt den Grundkörper 1 in einer Seitenansicht. In diesem ist in etwa mittig die Schlitzführung 6 angeordnet. Die Schlitzführung 6 ist in zwei unterschiedliche Führungskulissen 7 und 8 aufgeteilt. Die flachere Führungskulisse 7 verläuft in einem Winkel von etwa 5° in Bezug zur Längsachse des Grundkörpers 1. Das Bewegen der Rollen 2, 2' über die Welle 4 in dieser Führungskulisse 7 bewirkt ein Abbremsen des Jalousiezuges. Die Führungskulisse 8 verläuft wesentlich steiler. Der Winkel beträgt in etwa 30° in Bezug auf die Längsachse des Grundkörpers 1. Beim Bewegen der Rollen 2, 2' über die Welle 4 in dieser Führungskulisse 8 wird die Bremswirkung auf den Jalousiezug aufgehoben.The Fig. 3 shows the main body 1 in a side view. In this center slot guide 6 is arranged approximately. The slot guide 6 is divided into two different guide slots 7 and 8. The flatter guide slot 7 extends at an angle of about 5 ° with respect to the longitudinal axis of the main body 1. Moving the rollers 2, 2 'on the shaft 4 in this guide slot 7 causes a slowing down of the blind train. The guide slot 8 is much steeper. The angle is approximately 30 ° with respect to the longitudinal axis of the base body 1. When moving the rollers 2, 2 'on the shaft 4 in this guide slot 8, the braking effect on the blind pull is canceled.

In der Fig. 4 sind die Endlagen 9 und 10 der Rollen 2, 2' im Grundkörper 1 dargestellt. Befinden sich die Rollen 2, 2' - hier strichpunktiert dargestellt - in der oberen Endlage 9, ist die Bremswirkung vollständig aufgehoben. Der Jalousiezug lässt sich frei innerhalb der Führungsnuten bewegen. Befinden sich die Rollen 2, 2' in der unteren Endlage 10, wird der größtmögliche Druck auf den Jalousiezug erreicht. Dieser wird über in der Ringnut 12, 12' der Rollen 2, 2' befindlichen Ringelemente 3, 3' abgebremst und mit seiner Außenseite gegen die Außenkante der Führungsnut gedrückt und somit die Reibungskraft erhöht. Der Jalousiezug wird abgebremst.In the Fig. 4 the end positions 9 and 10 of the rollers 2, 2 'in the base body 1 are shown. Are the rollers 2, 2 '- shown here in phantom - in the upper end position 9, the braking effect is completely eliminated. The blind pull can be moved freely within the guide grooves. Are the rollers 2, 2 'in the lower end position 10, the greatest possible pressure on the shutter pull is achieved. This is braked over in the annular groove 12, 12 'of the rollers 2, 2' located ring elements 3, 3 'and pressed with its outer side against the outer edge of the guide groove and thus increases the frictional force. The blind pull is slowed down.

Die erfindungsgemäße Bremsvorrichtung wird in sogenannten Rollschränken verwendet. Die Frontseite wird durch einen Jalousiezug verschlossen. Beim Öffnen wird der Jalousiezug in einer Schnecke bzw. auf einer Rolle aufgewickelt.
Da der Jalousiezug von oben öffnet und beim Aufsperren durch das Eigengewicht aus der Schnecke fährt, kann dies bei ungebremsten Ausführungen zu Verletzungen des Bedieners bzw. zu Beschädigungen am Jalousiezug/Schrank führen.
Durch die beiden nebeneinanderliegenden Rollen 2, 2' wird der Jalousiezug abgebremst. Dazu verfährt die Welle 4 der Rollen 2, 2' in die Führungskulisse 7 bis in die untere Endlage 10. Beim Hochziehen des Jalousiezuges klinken sich die über die Welle 4 verbundenen Rollen 2, 2' aus und der Jalousiezug kann ohne spürbares Hindernis wieder nach oben gezogen werden.
Durch die beiden Ringelemente 3, 3' auf den Rollen 2, 2', die in diesem Ausführungsbeispiel als Silikonringe ausgeführt sind, benötigt man keinen zusätzlichen Bremsschuh, der sehr genau auf der innenliegenden Seite des Jalousiezuges montiert werden muss, um eine optimale Bremswirkung zu erzielen.The braking device according to the invention is used in so-called roll cabinets. The front side is closed by a blind pull. When opening, the blind pulls up in a worm or on a roll.
Since the shutter pulls open from above and moves out of the screw during unlocking due to its own weight, unrestrained implementations can lead to operator injuries or damage to the pull-pull / cabinet.
By the two adjacent rollers 2, 2 'of the blind train is braked. To do so, the shaft 4 moves the rollers 2, 2 'in the guide slot 7 to the lower end position 10. When pulling up the blind pull the connected via the shaft 4 rollers 2, 2' and the blind pull can without noticeable obstacle back up to be pulled.
By the two ring elements 3, 3 'on the rollers 2, 2', which are designed in this embodiment as silicone rings, you need no additional brake shoe, which must be mounted very accurately on the inner side of the blind pull to achieve optimum braking effect ,
