Description

Die vorliegende Erfindung betrifft eine Bremsvorrichtung, insbesondere eine Auflaufbremse, für eine Schiebetür oder Schiebefenster, insbesondere Hebe-Schiebe-Tür, gemäß dem Oberbegriff des Anspruchs 1 , sowie eine Schiebetür oder Schiebefenster, insbesondere Hebe-Schiebe-Tür, gemäß dem Oberbegriff des Anspruchs 13.The present invention relates to a braking device, in particular a overrun brake, for a sliding door or sliding window, in particular lifting-sliding door, according to the preamble of claim 1, and a sliding door or sliding window, in particular lifting-sliding door, according to the preamble of claim 13 ,

Hebe-Schiebetüren sind aufgrund Ihrer Konstruktionsart besonders für großflächige Öffnungselemente geeignet. Durch die zusätzlichen Anforderungen an den Wärmeschutz in modernen Baukörpern und den daraus resultierenden Dreifach-Verglasungen ergeben sich bei diesen Elementen sehr große Flügelgewichte. Beim Schließen einer solchen Schiebetür wird nun durch die große Flügelmasse in Verbindung mit der Schließgeschwindigkeit eine große Bewegungsenergie aufgebaut, die beim Auftreffen des Flügels auf den Blendrahmen abgebaut werden muss. Dies geschieht in der Regel über die Anschlagdichtungen des Flügels, die aber nur einen sehr kleinen Arbeitsweg zur Verfügung haben. Die Belastung auf den Rahmen und den Anschluss sind demzufolge sehr groß und können zu Beschädigungen führen.Lifting / sliding doors are particularly suitable for large opening elements due to their design. Due to the additional requirements for thermal insulation in modern structures and the resulting triple glazing, these elements result in very large sash weights. When closing such a sliding door, a large kinetic energy is now built up by the large wing mass in conjunction with the closing speed, which must be reduced when the wing hits the frame. This is usually done via the stop seals the wing, but only a very small way to work available. The load on the frame and the connection are therefore very large and can lead to damage.

Es sind Konstruktionen auf dem Markt bekannt, die dieses Problem angehen. Eine Bremsvorrichtung für den waagerecht verschiebbaren Flügel einer Schiebetür oder eines Schiebefensters wird beispielsweise in der Auslegeschrift DE 1 559 726 beschrieben. Im Wesentlichen kommt hier ein verschiebbarer Bremsschuh zum Einsatz, der beispielsweise an dem Blendrahmen angebracht ist und auf den Flügelrahmen bremsend einwirkt. Beim Schließen der Tür läuft der Flügelrahmen kurz vor dem Schließzustand der Tür auf den Bremsschuh auf. Der Bremsschuh ist derart aufgenommen, dass er bei dieser Bewegungsrichtung des Flügels nicht ausweichen kann und den Flügel entsprechend abbremst. Wird die Tür wieder geöffnet, wird der Bremsschuh gegen die Kraft einer mechanischen Feder zurückgedrückt und schleift nur noch leicht über den Flügelrahmen, entwickelt demnach keine allzu große Bremswirkung mehr.Constructions are known in the market that address this problem. A braking device for the horizontally displaceable wing of a sliding door or a sliding window is, for example, in the Auslegeschrift DE 1 559 726 described. Essentially, here comes a sliding brake shoe used, which is attached for example to the frame and acting on the sash frame braking. When closing the door of the sash runs shortly before the closed state of the door on the brake shoe. The brake shoe is accommodated such that it can not escape in this direction of movement of the wing and decelerates the wing accordingly. When the door is opened again, the brake shoe is pushed back against the force of a mechanical spring and only slightly grinds over the sash, so it does not develop too much braking effect.

Diese Konstruktion weist einige Nachteile auf. Der Bremsschuh unterliegt einem dauerhaften Verschleiß, da der Bremsschuh nicht nur beim Schließen, sondern konstruktionsbedingt auch beim Öffnen der Tür über den Flügelrahmen schleift. Auch unterliegen zahlreiche weitere mechanische Komponenten, wie beispielsweise die Führung des Bremsschuhs und die Rückstellfeder, einem Verschleiß. Hieraus ergibt sich ein nicht unbeachtlicher Wartungsaufwand, der noch dadurch erschwert werden kann, dass die Bremsvorrichtung in einem schwer zugänglichen Teil der Schiebetür angebracht ist.This construction has some disadvantages. The brake shoe is subject to permanent wear, as the brake shoe grinds not only when closing, but also by design when opening the door on the sash. Also, numerous other mechanical components, such as the leadership of the brake shoe and the return spring, subject to wear. This results in a not inconsiderable maintenance, which can be made even more difficult by the fact that the brake device is mounted in a hard to reach part of the sliding door.

Hier setzt die vorliegende Erfindung an und macht es sich zur Aufgabe, eine verbesserte Bremsvorrichtung für eine Schiebetür vorzuschlagen, insbesondere eine Bremsvorrichtung vorzuschlagen, welche einen geringeren Verschleiß bzw. Wartungsaufwand ermöglicht.This is where the present invention sets out and makes it its mission to propose an improved braking device for a sliding door, in particular to propose a braking device which allows less wear or maintenance.

Erfindungsgemäß wird die Aufgabe durch eine Bremsvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dadurch, dass die Bremsvorrichtung ein pneumatisches Bremsmittel aufweist, wird der Einsatz mechanischer Komponenten auf ein Minimum reduziert. Durch die Betätigung des pneumatischen Bremsmittels wird Luft komprimiert und durch die Komprimierung der Luft wird die aufgebaute Energie in Wärme umgewandelt, wodurch der Flügelrahmen der Schiebetür abgebremst werden kann. Im Ergebnis ist die vorgeschlagene Bremsvorrichtung sehr wartungsarm. Ferner ergeben sich durch die grundsätzlich pneumatische Ausgestaltung des Bremsmittels zahlreiche einfache Einstellungsmöglichkeiten hinsichtlich des Bremsverhaltens und der einfachen Ansteuerung beispielsweise eines zweiten Bremsmittels.According to the invention the object is achieved by a braking device with the characterizing features of claim 1. The fact that the brake device has a pneumatic braking means, the use of mechanical components is reduced to a minimum. By the operation of the pneumatic braking means, air is compressed and by the compression of the air is the converted energy into heat, whereby the sash of the sliding door can be slowed down. As a result, the proposed braking device is very low maintenance. Furthermore, due to the basically pneumatic design of the brake means numerous simple adjustment options with regard to the braking behavior and the simple control, for example, a second braking means.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Bremsvorrichtung ergeben sich insbesondere aus den Unteransprüchen. Die Merkmale der Unteransprüche können grundsätzlich beliebig miteinander kombiniert werden.Further advantageous embodiments of the braking device according to the invention will become apparent in particular from the dependent claims. The features of the subclaims can basically be combined with each other arbitrarily.

In einer vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass das erste Bremsmittel einen Zylinder und eine in dem Zylinder verfahrbare Kolbenstange mit einen Kolben umfasst. Diese Bauform eignet sich in besonders vorteilhafter Weise für ein pneumatisches Bremsmittel, da der Aufbau sehr einfach und bei geeigneter Ausgestaltung auch entsprechend wartungsarm ist.In an advantageous embodiment of the braking device can be provided that the first brake means comprises a cylinder and a movable piston rod in the cylinder with a piston. This design is particularly suitable for a pneumatic braking means, since the structure is very simple and with a suitable design also low maintenance.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die Kolbenstange mit einem Magnetkopf ausgestattet ist, wobei das Bremsmittel ferner einen Anschlag umfasst, wobei in einem Einbauzustand der Bremsvorrichtung der Magnetkopf zum Einschieben der Kolbenstange mit dem Anschlag in Kontakt treten kann und der Anschlag ferner dazu eingerichtet ist, dass der Magnetkopf zum Ausziehen der Kolbenstange daran haftet. Mit einer derartig ausgestalteten Bremsvorrichtung lässt sich folgendes Funktionsprinzip der Bremsvorrichtung realisieren. Die Bremsvorrichtung ist in einem Schiebefenster mit einem verschiebbaren Flügelrahmen und einem feststehenden Blendrahmen verbaut. In einem Ausgangszustand ist die Schiebetür geschlossen und wird geöffnet, sprich der Flügelrahmen wird zur Seite geschoben. Hierbei wird die Kolbenstange, die mittels des Magnetkopfes an den Anschlag gekoppelt ist, herausgezogen. Ist bei fortlaufender Bewegung die maximale Auszugslänge der Kolbenstange erreicht, so reißt der Magnet vom Anschlag ab. Der Flügelrahmen kann ohne Einschränkungen bis zur maximalen Öffnungsweite geöffnet werden. Durch diese Ausgestaltung der Bremsvorrichtung ist insbesondere die Baugröße der Bremsvorrichtung unabhängig von der Öffnungsweite des Flügelrahmens. Beim Schließvorgang trifft die ausgezogene Kolbenstange auf den Anschlag und wird durch die fortlaufende Bewegung in den Zylinder gedrückt. Hierdurch steigt der Druck im Zylinder an. Nachdem der Flügelrahmen in ausreichendem Maße abgebremst ist, kann der Druck, beispielsweise durch eine geeignete Entlüftung, so weit abgebaut sein, dass die Bremse wieder deaktiviert ist. Vorzugsweise ist das Bremsmittel gerade dann drucklos, wenn die Schiebetür wieder geschlossen ist. Für den Beginn des Öffnungsvorgangs ist vorzugsweise vorgesehen, dass die Bremsvorrichtung drucklos ist bzw. mit einem Rückschlagventil ausgestattet ist, so dass der Öffnungsbewegung auch keine Bremskraft entgegenwirkt.In a further advantageous embodiment of the braking device can be provided that the piston rod is equipped with a magnetic head, wherein the braking means further comprises a stop, wherein in an installed state of the braking device of the magnetic head for inserting the piston rod can come into contact with the stop and the stop is further adapted to the magnetic head adheres to pull out the piston rod. With a braking device designed in this way, the following operating principle of the braking device can be realized. The braking device is in a sliding window with a sliding sash and a fixed frame installed. In an initial state, the sliding door is closed and is opened, that is, the sash is pushed to the side. In this case, the piston rod, which is coupled by means of the magnetic head to the stop, pulled out. If the maximum extension length of the piston rod is reached during continuous movement, the magnet breaks away from the stop. The casement can be opened without restrictions up to the maximum opening width. Due to this configuration of the braking device, in particular the size of the braking device is independent of the opening width of the sash. During the closing process, the extended piston rod hits the stop and is pressed into the cylinder by the continuous movement. This increases the pressure in the cylinder. After the casement has been braked to a sufficient extent, the pressure, for example, by a suitable vent, be degraded so far that the brake is deactivated again. Preferably, the braking means is depressurized just when the sliding door is closed again. For the beginning of the opening operation is preferably provided that the braking device is depressurized or is equipped with a check valve, so that the opening movement also counteracts any braking force.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass das erste Bremsmittel, insbesondere der Kolben, mit einem Rückschlagventil ausgestattet ist. Durch diese Maßnahme kann die Kolbenstange bzw. der Kolben ohne einen relevanten Kraftaufwand, insbesondere aber ohne einen durch Unterdruck entstehenden Kraftaufwand, aus dem Zylinder herausgezogen werden.In a further advantageous embodiment of the braking device can be provided that the first brake means, in particular the piston, is equipped with a check valve. By virtue of this measure, the piston rod or the piston can be pulled out of the cylinder without a relevant expenditure of force, but in particular without a force arising due to negative pressure.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die Bremsvorrichtung ein zweites Bremsmittel umfasst, welches mindestens pneumatisch mit dem ersten Bremsmittel verbunden ist, wobei das zweite Bremsmittel eine Bremsbacke und ein pneumatisches Antriebsmittel zur Bewegung, insbesondere zum Schwenken, der Bremsbacke umfasst. Durch ein zweites Bremsmittel kann beispielsweise eine Rücklaufbremse realisiert werden. Durch den im ersten Bremsmittel beim Schließvorgang aufgebauten Druck könnte der Flügelrahmen nach dem Stillstand wieder zurückschnellen. Um dies zu vermeiden ist die Rücklaufbremsvorrichtung vorgesehen. Hierbei wird durch den beim Schließvorgang aufgebauten Druck im ersten Bremsmittel das zweite Bremsmittel aktiviert. Bei der Rückwärtsbewegung des Flügelrahmens kann die Bremsbacke mit dem Flügelprofil in Kontakt treten und so einer durch das erste Bremsmittel initiierten Öffnungsbewegung entgegenwirken. Vorzugsweise drückt sich die Bremsbacke wie ein Keil zwischen Flügelrahmen und Blendrahmen und verhindert damit diese Bewegung. Da der Druck in der Bremsvorrichtung bei Stillstand kontinuierlich, beispielsweise über eine Entlüftung, abnehmen kann, können die Bremsbacke und der diese antreibende Kolben über ein Federelement wieder in ihre Ausgangslage zurückgedrückt werden. Grundsätzlich kann das zweite Bremsmittel aber auch zur Unterstützung des ersten Bremsmittels eingesetzt werden, wobei das erste Bremsmittel aber auch ganz ohne das zweite Bremsmittel funktionsfähig ist. Auch können das erste Bremsmittel und das zweite Bremsmittel lediglich pneumatisch miteinander verbunden sein, insbesondere eine Leitung zwischen dem Zylinder des ersten Bremsmittels und dem Zylinder des zweiten Bremsmittels vorgesehen sein. Diese Leitung kann grundsätzlich beliebig ausgestaltet sein, beispielsweise als flexible Leitung, insbesondere als Schlauch. Diese Ausgestaltung bietet sich an, wenn erstes Bremsmittel und zweites Bremse beispielsweise an entfernten Orten in der Schiebetür verbaut werden sollen. Hierdurch ergibt sich beispielsweise eine große Flexibilität hinsichtlich des Anwendungsbereiches. Grundsätzlich können die Bremsmittel auch unmittelbar miteinander verbunden werden, beispielsweise wird der Montagebock des zweiten Bremsmittels unmittelbar an dem Zylinder des ersten Bremsmittels befestigt und die pneumatische Leitung als Bohrung innerhalb des Montagebocks ausgestaltet. Hierdurch ergibt sich eine sehr kompakte Bauweise.In a further advantageous embodiment of the braking device can be provided that the braking device comprises a second braking means which is at least pneumatically connected to the first braking means, wherein the second braking means comprises a brake shoe and a pneumatic drive means for moving, in particular for pivoting, the brake shoe. By a second braking means, for example, a return brake can be realized. By built up in the first braking means during the closing pressure of the sash could snap back after a standstill again. To avoid this, the return brake device is provided. In this case, the second braking means is activated by the pressure built up during the closing process in the first braking means. During the backward movement of the sash frame, the brake shoe can come into contact with the sash profile and thus counteract an opening movement initiated by the first brake means. Preferably, the brake shoe presses like a wedge between sash and frame and thus prevents this movement. Since the pressure in the brake device at standstill continuously, for example via a vent, can decrease, the brake shoe and this driving piston can be pushed back via a spring element to its original position. In principle, however, the second braking means can also be used to support the first braking means, but the first braking means is also able to function without the second braking means. Also, the first brake means and the second brake means may be only pneumatically connected to each other, in particular a conduit between the cylinder of the first brake means and the cylinder of the second brake means may be provided. This line can basically be configured as desired, for example as a flexible line, in particular as a hose. This embodiment lends itself to when first brake means and second Brake be installed, for example, at remote locations in the sliding door. This results, for example, in a great flexibility with regard to the field of application. In principle, the brake means can also be connected directly to one another, for example the mounting bracket of the second brake means is fastened directly to the cylinder of the first brake means and the pneumatic line is designed as a bore within the mounting bracket. This results in a very compact design.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die Bremse einen Montagebock umfasst. Bei dem Montagebock handelt es sich vorzugsweise um ein Formteil, welches durch Spritzguss oder ein ähnliches Verfahren hergestellt werden kann. Insofern können hier verschiedene Funktionen in den Montagebock integriert werden.In a further advantageous embodiment of the braking device can be provided that the brake comprises a mounting bracket. The mounting bracket is preferably a molded part which can be produced by injection molding or a similar method. In this respect, various functions can be integrated into the assembly stand here.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die Bremsbacke bewegbar, insbesondere um eine Achse schwenkbar, in dem Montagebock aufgenommen ist, wobei das Antriebsmittel einen Zylinder und einen bewegbar in dem Zylinder aufgenommenen Kolben umfasst, wobei der Kolben mit der Bremsbacke in Kontakt treten kann. Eine derartige schwenkbare Aufnahme der Bremsbacke in Zusammenschau mit der ZylinderKolben Kombination stellt eine einfache und kostengünstige, vor allem aber wartungsarme Ausgestaltung eines zweiten Bremsmittels dar, das von dem pneumatischen ersten Bremsmittel angesteuert werden kann. Über die entsprechende Ausgestaltung der Hebelarmverhältnisse kann zudem auf beispielsweise kleiner gebaute Bremsmittel zurückgegriffen werden.In a further advantageous embodiment of the braking device can be provided that the brake shoe is movable, in particular mounted pivotable about an axis in the mounting bracket, wherein the drive means comprises a cylinder and a piston movably received in the cylinder, wherein the piston with the brake shoe in Can contact. Such a pivotable receiving the brake shoe in conjunction with the cylinder piston combination represents a simple and inexpensive, but especially low-maintenance design of a second brake means, which can be controlled by the pneumatic first brake means. On the appropriate design of Hebelarmverhältnisse can also be used, for example, smaller built brake means.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass das zweite Bremsmittel, insbesondere die Bremsbacke, mit einer Rückstelleinrichtung, insbesondere einer Feder um die Achse, ausgestattet ist. Über eine derartige Maßnahme kann sichergestellt werden, dass die zweite Bremsvorrichtung nicht länger aktiv ist, als es für ein Abbremsen des Flügelrahmens notwendig ist. Es kann insbesondere sichergestellt werden, dass die Bremsbacke nicht unnötig, beispielsweise beim Öffnen des Flügelrahmens, abgenutzt wird.In a further advantageous embodiment of the braking device can be provided that the second braking means, in particular the brake shoe, with a return device, in particular a spring about the axis, is equipped. Such a measure can ensure that the second braking device is no longer active, as it is necessary for a deceleration of the sash. In particular, it can be ensured that the brake shoe is not unnecessarily worn, for example when the casement is opened.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass das erste Bremsmittel mit einem Anschlussmittel, insbesondere der Zylinder mit einem Anschlussmittel und/oder der Anschlag mit einem Anschlussmittel, und/oder das zweite Bremsmittel mit einem Anschlussmittel, insbesondere der Montagebock mit einem Anschlussmittel, zur Montage an einem Blend- oder Flügelrahmen ausgestattet ist. Hierdurch kann die Bremsvorrichtung, insbesondere deren einzelne Komponenten, sicher an einem Blend- oder Flügelrahmen befestigt werden.In a further advantageous embodiment of the braking device can be provided that the first braking means with a connection means, in particular the cylinder with a connection means and / or the stop with a connection means, and / or the second brake means with a connection means, in particular the mounting bracket with a connection means , equipped for mounting on a glare or sash frame. As a result, the braking device, in particular its individual components, can be securely fastened to a glare or casement frame.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass das erste Bremsmittel und das zweite Bremsmittel, insbesondere der Montagebock und der Zylinder, in einer Flucht hintereinander angeordnet sind, insbesondere der Montagebock unmittelbar mit dem Zylinder verbunden ist. Durch diese Maßnahme ergibt sich eine kompakte Bauform der Bremsvorrichtung.In a further advantageous embodiment of the invention can be provided that the first brake means and the second brake means, in particular the mounting bracket and the cylinder are arranged in alignment in a row, in particular the mounting bracket is directly connected to the cylinder. This measure results in a compact design of the braking device.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die Bremsvorrichtung, insbesondere der Zylinder des ersten Bremsmittels und/oder der Zylinder der zweiten Bremsvorrichtung, mit einer Entlüftung, insbesondere einer einstellbaren Entlüftung, verbunden bzw. ausgestattet ist. Mit einer einstellbaren Entlüftung kann die Bremsvorrichtung optimal an eine Schiebetür angepasst werden. Durch eine einstellbare Entlüftungsöffnung kann die Bremsvorrichtung auf unterschiedliche Flügelgewichte und Schließgeschwindigkeiten angepasst werden. Es kann somit eingestellt werden, ob der Flügel bei normaler Schließgeschwindigkeit die Endposition erreicht oder ob er schon vor dieser Position zum Stillstand kommen soll, wodurch beispielsweise ein Klemmschutz gewährleistet werden kann. Mit der einstellbaren Entlüftung ggf. in Zusammenspiel mit einer Rückstelleinrichtung des zweiten Bremsmittels, kann auch ein Handhabungsnachteil bei bekannten Bremsvorrichtungen für Schiebetüren (beispielsweise DE 1 559 726 ) überwunden werden. Der Handhabungsnachteil beruht im Wesentlichen darauf, dass neben der ohnehin zu überwindenden Reibung beim Öffnen der Schiebetür, Reibkräfte durch ein Schleifen des Bremsschuhs hinzukommen. Dieses Problem ist mit den vorgeschlagenen mechanischen Konstruktionen der DE 1 559 726 nicht oder zumindest nicht mit vertretbarem Aufwand lösbar, da die Ausweichbewegung stets durch einen Kontakt des Bremsschuhs mit dem Flügelrahmen ausgelöst wird, d.h. ein Schleifen des Bremsschuhs unabhängig von der jeweiligen Bewegungsrichtung ist unausweichlich. Hier bietet die erfindungsgemäße Bremsvorrichtung mit einer Entlüftung, insbesondere einer einstellbaren Entlüftung, Möglichkeiten zur Beeinflussung der Bremswirkung des zweiten Bremsmittels, insbesondere in Abhängigkeit vom Öffnungszustand der Schiebetür. Beispielsweise kann durch gezielten Druckverlust die Bremswirkung des zweiten Bremsmittels aufgehoben werden. Es kann beispielsweise sichergestellt werden, dass das zweite Bremsmittel in einem geschlossenen Ausgangszustand der Schiebetür vollständig drucklos ist und entsprechend deaktiviert ist. Hierdurch kann vermieden werden, dass zum Öffnen der Schiebetür eine Anfangsreibung der Bremsbacke überwunden werden muss bzw. die Bremsbacke unnötig abgenutzt wird.In a further advantageous embodiment of the braking device can be provided that the braking device, in particular the cylinder of the first braking means and / or the cylinder of the second braking device, with a vent, in particular a adjustable vent, connected or equipped. With an adjustable vent, the braking device can be optimally adapted to a sliding door. Through an adjustable vent opening, the braking device can be adapted to different sash weights and closing speeds. It can thus be adjusted whether the wing reaches the end position at normal closing speed or whether it should come to a standstill before this position, whereby, for example, a pinch protection can be ensured. With the adjustable vent possibly in conjunction with a restoring device of the second braking means, also a handling disadvantage in known braking devices for sliding doors (for example DE 1 559 726 ) are overcome. The handling disadvantage is based essentially on the fact that, in addition to the friction which has to be overcome anyway when opening the sliding door, frictional forces are added by grinding the brake shoe. This problem is with the proposed mechanical constructions of the DE 1 559 726 not or at least not solvable with reasonable effort, since the evasive movement is always triggered by a contact of the brake shoe with the sash, ie, a grinding of the brake shoe regardless of the direction of movement is inevitable. Here, the braking device according to the invention with a vent, in particular an adjustable vent, offers possibilities for influencing the braking action of the second braking means, in particular depending on the opening state of the sliding door. For example, the braking effect of the second braking means can be canceled by targeted pressure loss. It can be ensured, for example, that the second braking means is completely depressurized in a closed initial state of the sliding door and is correspondingly deactivated. This can be avoided that to open the sliding door a Initial friction of the brake shoe must be overcome or the brake shoe is worn out unnecessarily.

In einer weiteren vorteilhaften Ausgestaltung der Bremsvorrichtung kann vorgesehen sein, dass die pneumatische Verbindung zwischen dem ersten Bremsmittel und dem zweiten Bremsmittel als Leitung ausgestaltet ist, die zumindest abschnittsweise als Bohrung innerhalb des Montagebocks ausgestaltet ist, wobei die Entlüftung eine in den Montagebock eingedrehte Schraube, insbesondere Madenschraube, und eine Entlüftungsleitung umfasst, wobei die Schraube zur Einstellung des Durchtrittsquerschnitts zwischen der Leitung und der Entlüftungsleitung eingerichtet ist. Eine derartige Ausgestaltung der Leitung und der Entlüftung trägt weiterhin zu einer kompakten und preiswerten Bauweise der Bremsvorrichtung bei.In a further advantageous embodiment of the braking device can be provided that the pneumatic connection between the first braking means and the second braking means is designed as a line which is at least partially configured as a bore within the mounting bracket, wherein the vent screwed into the mounting bracket screw, in particular Grub screw, and a vent line, wherein the screw for adjusting the passage cross-section between the line and the vent line is set. Such a design of the line and the vent further contributes to a compact and inexpensive construction of the braking device.

Eine weitere Aufgabe der vorliegenden Erfindung liegt darin, eine verbesserte Schiebetür oder Schiebefenster, insbesondere Hebe-Schiebe-Tür, umfassend mindestens einen Blendrahmen, einen Flügelrahmen und eine zwischen Blendrahmen und Flügelrahmen angeordnete Bremsvorrichtung, bereitzustellen, insbesondere eine Schiebetür oder Schiebefenster, insbesondere Hebe-Schiebe-Tür, umfassend mindestens einen Blendrahmen, einen Flügelrahmen und eine zwischen Blendrahmen und Flügelrahmen angeordnete Bremsvorrichtung bereitzustellen, die wartungsärmer ist.A further object of the present invention is to provide an improved sliding door or sliding window, in particular a lift-and-slide door, comprising at least one frame, a sash and a braking device arranged between frame and sash, in particular a sliding door or sliding window, in particular lifting and sliding Door, comprising at least one frame, a sash and a arranged between the frame and sash brake device to provide, which is less expensive.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass es sich um eine Bremsvorrichtung gemäß mindestens einem der Ansprüche 1 bis 12 handelt. Eine derartige Schiebetür bzw. ein derartiges Schiebefenster ist besonders wartungsarm, da die Bremsvorrichtung bereits sehr wartungsarm ausgestaltet ist.According to the invention this object is achieved in that it is a braking device according to at least one of claims 1 to 12. Such a sliding door or such a sliding window is particularly low maintenance, since the brake device is already designed very low maintenance.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Schiebetür oder Schiebefenster ergeben sich insbesondere aus den Unteransprüchen. Die Merkmale der Unteransprüche können grundsätzlich beliebig miteinander kombiniert werden.Further advantageous embodiments of the sliding door or sliding window according to the invention will become apparent in particular from the dependent claims. The features of the subclaims can basically be combined with each other arbitrarily.

In einer vorteilhaften Ausgestaltung der Schiebetür oder des Schiebefensters kann vorgesehen sein, dass die Bremsvorrichtung in der Schiebetür bzw. dem Schiebefenster, insbesondere zwischen dem Blendrahmen und dem Flügelrahmen, insbesondere in einer oberen Beschlagkammer des Flügelrahmens, angeordnet ist. Hierdurch ergibt sich eine optisch ansprechende Schiebetür bzw. Schiebefenster, da die Bremsvorrichtung für den Betrachter weitgehend unsichtbar bleibt. Lediglich der Anschlag ist bei geöffnetem Flügelrahmen sichtbar.
In einer weiteren vorteilhaften Ausgestaltung der Schiebetür oder Schiebefenster kann vorgesehen sein, dass die Bremsvorrichtung, vorzugsweise der Montagebock, insbesondere die Schraube der Entlüftung, am Ende des Flügelrahmens, insbesondere im Bereich der Flügelrahmenecke, angeordnet ist. Durch die Positionierung der Bremsvorrichtung am Ende des Flügelrahmens, insbesondere im Bereich der Flügelrahmenecke, ist es durch eine Bohrung möglich, die Einstellschraube der Entlüftung im eingebauten Zustand mittels eines geeigneten Werkzeugs, beispielsweise durch einen Sechskantschlüssel, zu betätigen.In an advantageous embodiment of the sliding door or the sliding window can be provided that the braking device in the sliding door or the sliding window, in particular between the window frame and the sash, in particular in an upper fitting chamber of the sash is arranged. This results in a visually appealing sliding door or sliding window, since the braking device remains largely invisible to the viewer. Only the stop is visible with the sash open.
In a further advantageous embodiment of the sliding door or sliding window can be provided that the braking device, preferably the mounting bracket, in particular the screw of the vent, at the end of the sash, in particular in the field of sash. By positioning the brake device at the end of the sash, in particular in the area of the sash corner, it is possible through a bore to operate the adjustment screw of the vent when installed by means of a suitable tool, for example by a hex wrench.

Nachfolgend wird der Einfachheit halber auf eine Schiebetür eingegangen. Eine Hebe-Schiebetür umfasst neben den ohnehin vorhandenen Linearlagern der Schiebetür einen entsprechenden Hebe-Schiebe-Mechanismus, dessen Details dem Fachmann hinreichend bekannt sind. Ein Schiebefenster ist im Wesentlichen wie eine Schiebetür ausgestaltet, wobei der Einsatzzweck jedoch abweicht. Auch diese Unterschiede bzw. Gemeinsamkeiten sind dem Fachmann hinreichend bekannt.Hereinafter, a sliding door will be discussed for the sake of simplicity. In addition to the already existing linear bearings of the sliding door, a lifting-sliding door comprises a corresponding lifting-sliding mechanism whose details are sufficiently known to the person skilled in the art.

Insofern ist zumindest das Anschlagmittel 15 vorzugsweise aus einem ferromagnetischen Material hergestellt.The cylinder 1 is designed substantially hollow cylindrical and equipped with at least one connecting means 13 for attachment to the wing frame 11 or frame 10. The piston rod 2 is end equipped with a magnetic head 3 and a piston 2a. The piston 2 a and a portion of the piston rod 2 is slidably received within the cylinder 1.

Das Antriebsmittel ist im Wesentlichen in einem Montagebock 5 untergebracht, der ebenfalls zur schwenkbaren Aufnahme der Bremsbacke 8 eingerichtet ist. Die Bremsbacke 8 ist im wesentlichen als flaches Formteil ausgestaltet und mittels einer Achse 16 mit dem Montagebock 5 verbunden. Die Achse 16 kann mit einem Federelement 9 ausgestattet sein. Die Bremsbacke 8 kann, wie hier vorgeschlagen, einen separaten Bremsbelag 8a aufweisen, jedoch auch einteilig ausgestaltet sein. Das Antriebsmittel umfasst im Wesentlichen einen Zylinder 17 und einen in dem Zylinder bewegbaren Kolben 7. Das erste Bremsmittel, insbesondere der Zylinder 1 , ist mit einem Anschluss zur mindestens pneumatischen Verbindung mit dem zweiten Bremsmittel, insbesondere dem Zylinder 17, ausgestattet. Entsprechend ist auch das zweite Bremsmittel, insbesondere der Zylinder 17, mit einem Anschluss zur mindestens pneumatischen Verbindung mit dem ersten Bremsmittel, insbesondere dem Zylinder 1 , ausgestattet. In der vorliegenden bevorzugten Ausführungsform wird die pneumatische Verbindung durch die als Bohrung innerhalb des Montageblocks ausgestaltete Leitung 18 ausgebildet, die einerseits in dem Zylinder 1 und andererseits in dem Zylinder 17 mündet. Vorzugsweise sind erstes Bremsmittel und zweites Bremsmittel auch jeweils mit einem mechanischen Anschluss zur unmittelbaren Verbindung ausgestattet, die beispielsweise als Gewinde- oder Steckverbindung 20 ausgestaltet sein kann. Ferner ist die Leitung 18 mit einer Entlüftung 6a ausgestattet, deren Durchsatz über eine Schraube 6, insbesondere Madenschraube, einstellbar ist. Auch das zweite Bremsmittel II, insbesondere der Montagebock 5, ist mit einem Anschlussmittel 19 zur Anbringung an den Flügelrahmen 11 oder Blendrahmen 10 ausgestattet.The drive means is substantially accommodated in a mounting bracket 5, which is also arranged to pivotally receive the brake shoe 8. The brake shoe 8 is designed substantially as a flat molded part and connected by means of an axis 16 with the mounting bracket 5. The axle 16 may be equipped with a spring element 9. The brake shoe 8 may, as proposed here, have a separate brake pad 8a, but also be designed in one piece. The drive means essentially comprises a cylinder 17 and a piston 7 which is movable in the cylinder. The first brake means, in particular the cylinder 1, is provided with a connection to the at least pneumatic connection to the second brake means, in particular the cylinder 17. Accordingly, the second brake means, in particular the cylinder 17, with a connection to the at least pneumatic connection to the first braking means, in particular the cylinder 1, equipped. In the presently preferred embodiment, the pneumatic connection is formed by the designed as a bore within the mounting block line 18, which opens on the one hand in the cylinder 1 and on the other hand in the cylinder 17. Preferably, first brake means and second brake means are also each equipped with a mechanical connection for direct connection, which may be configured, for example, as a threaded or plug connection 20. Further is the line 18 is equipped with a vent 6a, the throughput of a screw 6, in particular grub screw, is adjustable. Also, the second braking means II, in particular the mounting bracket 5, is equipped with a connection means 19 for attachment to the wing frame 11 or frame 10.

Insofern sind in der hier beschriebenen bevorzugten Ausführungsform das erste Bremsmittel I und das zweite Bremsmittel II sowohl mechanisch, als auch pneumatisch unmittelbar miteinander verbunden, wodurch sich eine besonders kompakte Ausgestaltung der Bremsvorrichtung ergibt. Auch sind erstes Bremsmittel und zweites Bremsmittel in der hier beschriebenen bevorzugten Ausführungsform in einer Flucht hintereinander angeordnet, so dass sich die Bremsvorrichtung optimal in ein in der Regel längliches Rahmenprofil integrieren lässt. Denkbar ist aber auch eine pneumatisch Verbindung mittels Pneumatikschlauch oder ähnlichen Mitteln, so dass erstes Bremsmittel und zweites Bremsmittel als separate Teile ausgeführt sind. Hierdurch kann die Bremsvorrichtung sehr flexibel auf die jeweiligen Anforderungen der Schiebtür angepasst werden. Denkbar ist auch der Zusammenschluss mehrerer erster Bremsmittel und/oder zweiter Bremsmittel zu einer erfindungsgemäßen Bremsvorrichtung, beispielsweise für sehr große und/oder schwere Schiebetürkonstruktionen.In this respect, in the preferred embodiment described here, the first brake means I and the second brake means II are connected both mechanically and pneumatically directly to each other, resulting in a particularly compact design of the brake device. Also, first brake means and second brake means are arranged in alignment in the preferred embodiment described here in succession, so that the brake device can be optimally integrated into a generally elongated frame profile. It is also conceivable, however, a pneumatic connection by means of pneumatic hose or similar means, so that first brake means and second braking means are designed as separate parts. As a result, the braking device can be adapted very flexibly to the respective requirements of the sliding door. Also conceivable is the merger of a plurality of first braking means and / or second braking means to a braking device according to the invention, for example, for very large and / or heavy sliding door structures.

Bevorzugterweise sind die Bremsmittel bzw. die Bremsvorrichtung in der Schiebetür befestigt, Insbesondere sind der Zylinder 1 und der Montagebock 5 mittels der jeweiligen Anschlussmittel 13, 19 an dem Flügelrahmen 11 und der Anschlag 4 über das Anschlussmittel 14 an dem Blendrahmen 10 angebracht. Die Bremsbacke 8 ist dabei so ausgerichtet, dass sie mit dem Blendrahmen 10 in Kontakt treten kann. Weiterhin bevorzugt, ist die Bremsvorrichtung V innerhalb der Schiebetür, insbesondere zwischen dem Blendrahmen 10 und dem Flügelrahmen 1 1 , angebracht. Grundsätzlich sind aber auch weitere geeignete Montagepositionen denkbar.Preferably, the braking means and the braking device are mounted in the sliding door, in particular, the cylinder 1 and the mounting bracket 5 by means of the respective connection means 13, 19 attached to the sash 11 and the stop 4 via the connecting means 14 on the frame 10. The brake shoe 8 is aligned so that it can come into contact with the frame 10 in contact. Further preferably, the braking device V is within the Sliding door, in particular between the frame 10 and the sash 1 1, attached. In principle, however, other suitable mounting positions are conceivable.

Weitere Details der vorliegenden Erfindung ergeben sich aus einer beispielhaften Funktionsbeschreibung der Schiebetür bzw. der Bremsvorrichtung.Further details of the present invention will become apparent from an example of a functional description of the sliding door or the braking device.

Als Ausgangszustand wird von einer geschlossenen Schiebtür ausgegangen, wie sie beispielsweise in Fig. 4 dargestellt ist.The initial state is assumed to be a closed sliding door, as used, for example, in US Pat Fig. 4 is shown.

Der Flügelrahmen 11 wird geöffnet, sprich der Flügelrahmen 11 wird zur Seite geschoben, bis er beispielsweise eine Position gemäß Fig. 4a erreicht hat. Hierbei wird die Kolbenstange 2, die mittels des Magnetkopf 3 an den Anschlag 4 gekoppelt ist, herausgezogen. Ist bei fortlaufender Bewegung die maximale Auszugslänge der Kolbenstange 2 erreicht, so reißt der Magnet 3 vom Anschlag 4 ab.The casement 11 is opened, that is, the casement 11 is pushed to the side until, for example, a position according to Fig. 4a has reached. In this case, the piston rod 2, which is coupled by means of the magnetic head 3 to the stop 4, pulled out. If the maximum extension length of the piston rod 2 is reached during continuous movement, the magnet 3 tears off the stop 4.

Das erste Bremsmittel, insbesondere der Kolben 7, ist vorzugsweise mit einem Rückschlagventil ausgestattet, welches ein Ausziehen der Kolbenstange 2 nahezu ohne Kraftaufwand ermöglicht. Hierzu öffnet das Rückschlagventil bei Unterdruck im Zylinder 1 , sprich wenn die Kolbenstange 2 aus dem Zylinder 1 herausgezogen wird, und schließt bei Druck, sprich sobald die Kolbenstange 2 in den Zylinder 1 eingeschoben wird. Das Rückschlagventil kann beispielsweise als entsprechend gestalteter Kolbenring des Kolbens 7 ausgestaltet sein. Der Kolbenring ist vorzugsweise ein O-Ring. Bei der Vorwärtsbewegung des Kolbens liegt der O-Ring an der Seitenwand der Kolbenringnut und an der Zylinderwand an und dichtet hier ab. Bei der Rückwärtsbewegung des Kolbens hebt der O-Ring von der Seitenwand der Kolbenringnut ab und die Luft kann unter dem O-Ring hindurch strömen.The first braking means, in particular the piston 7, is preferably equipped with a check valve, which allows a withdrawal of the piston rod 2 with almost no effort. For this purpose, the check valve opens at negative pressure in the cylinder 1, that is, when the piston rod 2 is pulled out of the cylinder 1, and closes when pressure, that is, as soon as the piston rod 2 is inserted into the cylinder 1. The check valve may be configured, for example, as a correspondingly shaped piston ring of the piston 7. The piston ring is preferably an O-ring. During the forward movement of the piston, the O-ring abuts against the side wall of the piston ring groove and on the cylinder wall and seals off here. During the backward movement of the piston, the O-ring lifts from the Side wall of the piston ring groove and the air can flow under the O-ring.

Der Flügelrahmen 11 kann ohne Einschränkungen bis zur maximalen Öffnungsweite geöffnet werden. Beim Schließvorgang, angedeutet durch die Schließbewegung gemäß den Pfeilen in den Fig. 4a bis 4c, trifft die ausgezogene Kolbenstange 2 auf den Anschlag 4 auf und wird durch die fortlaufende Bewegung in den Zylinder 1 gedrückt. Hierdurch steigt der Druck im Zylinder 1 an. Über die am Ende des Zylinders 1 im Montagebock 5 angebrachte einstellbare Entlüftung 6, 6a entweicht kontinuierlich Luft. Nichtsdestotrotz entfaltet das erste Bremsmittel hier bereits eine Bremswirkung, da Luft komprimiert werden muss.The sash 11 can be opened without restrictions up to the maximum opening width. When closing, indicated by the closing movement according to the arrows in the Fig. 4a to 4c , the extended piston rod 2 strikes the stop 4 and is pressed into the cylinder 1 by the continuous movement. As a result, the pressure in the cylinder 1 increases. Through the mounted at the end of the cylinder 1 in the mounting bracket 5 adjustable vent 6, 6a escapes continuously air. Nevertheless, the first brake means already has a braking effect here, since air must be compressed.

Gleichzeitig wird der im Montagebock 5 angebrachte Kolben 7 durch den im Zylinder 1 herrschenden Druck herausgedrückt. Der Kolben 7 wiederum drückt die Bremsbacke 8 mit dem aufgebrachten Bremsbelag 8a an den Blendrahmen 10, insbesondere dessen oberes Blendrahmenprofil. Durch den ansteigenden Druck wird die Andruckkraft auf die Bremsbacke 8 größer, so dass die Bewegung des Flügelrahmens 11 zusätzlich abgebremst wird. Insofern unterstützt das zweite Bremsmittel das erste Bremsmittel durch die Reibung der Bremsbacke an dem Blendrahmen 10.At the same time, the piston 7 mounted in the mounting bracket 5 is pushed out by the pressure prevailing in the cylinder 1. The piston 7 in turn pushes the brake shoe 8 with the applied brake pad 8a to the frame 10, in particular its upper frame profile. Due to the increasing pressure, the pressing force on the brake shoe 8 is greater, so that the movement of the sash 11 is additionally braked. In this respect, the second brake means assists the first brake means by the friction of the brake shoe on the frame 10.

Kommt der Flügelrahmen 11 vor dem Anschlag 4 zum Stillstand, ist im Zylinder 1 noch kurzzeitig ein Restdruck, der den Flügelrahmen 11 wieder aufdrücken könnte. Dies wird durch das zweite Bremsmittel, insbesondere die Bremsbacke 8, verhindert. Insbesondere ist die Bremsvorrichtung, insbesondere die Entlüftung, so eingestellt, dass noch ein ausreichender Restdruck im Zylinder 17 vorhanden ist, der die Bremsbacke 8 gegen den Blendrahmen 10 drückt und entsprechend festhält. Ferner wird dem unbeabsichtigten Aufdrücken des Flügelrahmens auch noch durch die Form und Lage der Bremsbacke 8 entgegengewirkt. Die Bremsbacke 8 klemmt sich beim Einleiten der durch den Restdruck eingeleiteten unbeabsichtigten Öffnungsbewegung wie ein Keil zwischen Blendrahmen 10 und Flügelrahmen 11.If the casement 11 stops in front of the stop 4, there is still a residual pressure in the cylinder 1 for a short time, which could press the casement 11 back again. This is prevented by the second brake means, in particular the brake shoe 8. In particular, the brake device, in particular the vent, is set so that there is still a sufficient residual pressure in the cylinder 17, which presses the brake shoe 8 against the frame 10 and holds accordingly. Furthermore, the unintentional pressing of the sash also counteracted by the shape and position of the brake shoe 8. The brake shoe 8 clamps when initiating the initiated by the residual pressure unintentional opening movement as a wedge between the frame 10 and sash 11th

Sinkt der Druck im Zylinder 1 nun weiter ab, so wird der die Bremsbacke 8, 8a steuernde Kolben 7 und die Bremsbacke 8 über das Federelement 9 wieder in seine Ausgangsstellung zurückgedrückt. Grundsätzlich kann diese Rückstellfunktion aber auch durch Schwerkraft erreicht werden.If the pressure in the cylinder 1 now decreases further, the piston 7 controlling the brake shoe 8, 8a and the brake shoe 8 are pushed back into its starting position via the spring element 9. Basically, this reset function can also be achieved by gravity.

Der Bremseffekt beruht im Wesentlichen darauf, dass die Luft in dem Zylinder komprimiert und nur langsam über die Entlüftung abgelassen wird. Unterstützend kann die Bremsbacke den Flügelrahmen abbremsen. Das Bremsverhalten der Bremsvorrichtung kann im Wesentlichen durch die Schraube 6 der Entlüftung 6a eingestellt werden. Durch eine geeignete Abbremsung des Flügelrahmens 11 kann eine Beschädigung der Schiebtür im Wesentlichen ausgeschlossen werden.The braking effect is essentially due to the fact that the air in the cylinder is compressed and only slowly drained through the vent. Supportive, the brake shoe can slow down the sash. The braking behavior of the brake device can be adjusted substantially by the screw 6 of the vent 6a. By a suitable deceleration of the sash 11 damage to the sliding door can be substantially excluded.
