Abstract

Door with a braking stopper has a braking element arranged near to the bottom of the door. The braking element is moved by an actuator element from a retracted position when the door is closed to an extended position when the door is opened. Movement of the door activates the actuator. The door brake (3) is extended downwards from the door, by means of a pulling cable (6) anchored in the door frame, towards the ground to lock the door in an open position.

Description

Die Erfindung bezieht sich auf eine Tür mit einem im Bodenbereich der Tür angeordneten Bremselement, das verstellbar in der Tür geführt und über einen durch die Türbewegung betätigten Stelltrieb aus einer bei geschlossener Tür zurückgezogenen Grundstellung in seine bei geöffneter Tür die Türunterkante überragende Bremsstellung vorbewegbar ist.The invention relates to a door with a arranged in the bottom region of the door brake element, which is adjustably guided in the door and an actuated by the door actuator actuator from a retracted when the door closed basic position in his door open at the door lower edge superior braking position is vorbewegbar.

Bei einer derartigen Tür besteht der Stelltrieb beispielsweise aus einer entlang der Türunterkante schiebeverstellbar gelagerten Kulisse zur Schwenkverstellung des in Längsrichtung unverschiebbar geführten Bremselementes und aus einem Gestänge zur Anlenkung der Kulisse am Türstock oder am Fußboden ( AT 407 892 B ). Dabei wird durch ein Zusammenwirken von Bremselement und Stelltrieb das Bremselement in Abhängigkeit von der Öffnungsweite der Tür aus seiner Grundstellung in seine Bremsstellung bzw. aus seiner Bremsstellung in die Grundstellung verschwenkt und damit die Tür entweder in der vorbestimmten Offenstellung gebremst oder die Bewegung der Tür freigegeben. Das Bremselement und der Stelltrieb bleiben wegen ihrer Anordnung im Unterkantenbereich der Tür weitgehend unsichtbar, insbesondere da es keinen am Boden oder an einer Wand fest montierten Anschlag gibt. Von Nachteil ist bei dieser bekannten Vorrichtung allerdings die aufwendige Ausgestaltung des Stelltriebes in Form einer Kulissenführung, die einen erheblichen Platzbedarf hat, kostenintensiv anzufertigen und aufgrund des Gestänges umständlich zu montieren ist.In such a door, the actuator consists for example of a sliding along the lower edge sliding gate mounted for pivotal adjustment of the non-displaceably guided in the longitudinal direction of the brake element and a linkage for articulation of the backdrop on the door frame or on the floor ( AT 407 892 B ). In this case, the braking element is pivoted in response to the opening width of the door from its normal position to its braking position or from its braking position to the normal position and thus braked the door either in the predetermined open position or released the movement of the door. The brake element and the actuator remain largely invisible because of their arrangement in the lower edge region of the door, especially since there is no fixed to the ground or on a wall mounted stop. The disadvantage of this known device, however, the complex configuration of the actuator in the form of a slotted guide, which has a considerable footprint, costly to make and is awkward to assemble due to the linkage.

Zum Feststellen von Türen ist weiter bekannt ( WO 92/03630 A ), am Türblatt im Bereich der Türunterkante montierte Feststellelemente vorzusehen, mit denen eine Tür in beliebigen Öffnungswinkeln durch Verkeilen der Tür mit dem Boden festgestellt werden kann. Das Verkeilen oder Lösen der Tür erfolgt durch manuelles Absenken bzw. Anheben einer Exzenterrolle, wobei diese Verstellelemente zur Begrenzung des Öffnungswinkels einer Tür ungeeignet sind und sich auch nicht in ein Türblatt integrieren lassen.To detect doors is further known ( WO 92/03630 A ), to provide on the door leaf in the region of the lower edge of the door locking elements with which a door can be determined in any opening angles by wedging the door to the ground. The wedging or loosening of the door takes place by manually lowering or lifting an eccentric roller, wherein these adjusting elements are unsuitable for limiting the opening angle of a door and can not be integrated into a door leaf.

Ein Anschlagen von Türen an Wänden, Einrichtungsgegenständen oder anderen Hindernissen kann beispielsweise mittels Brems- oder Anschlagelementen aus Gummi bzw. Kunststoff verhindert werden, die am Boden, an einer Wand oder an den Einrichtungsgegenständen zu befestigen sind. Derartige Bremsstopper sind fest montiert und erlauben somit keine variable Begrenzung des Öffnungswinkels einer Tür sowie erschweren mit ihren fest montierten Stopperkörpern eine Bodenreinigung.An impact of doors on walls, furnishings or other obstacles can be prevented, for example, by means of brake or stop elements made of rubber or plastic, which are to be fastened to the floor, to a wall or to the furnishings. Such brake stops are firmly mounted and thus do not allow variable limitation of the opening angle of a door and complicate with their permanently mounted stopper bodies a floor cleaning.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Tür der eingangs geschilderten Art mit einem im Bodenbereich der Tür angeordneten Bremselement zu schaffen, deren Begrenzung des Öffnungswinkels mit möglichst einfachen Mitteln möglich ist und die sich durch ihre Funktionssicherheit sowie ihre einfache Montage und Ausgestaltung auszeichnet.The invention is therefore an object of the invention to provide a door of the type described with a arranged in the bottom region of the door brake element whose limitation of the opening angle is possible with the simplest possible means and which is characterized by their reliability and ease of installation and design.

Die Erfindung löst diese Aufgabe dadurch, daß der Stelltrieb wenigstens ein im Bereich der Türunterkante angeordnetes im montierten Zustand, einerends an einem Türstock oder am Fußboden von der Schwenkachse der Tür beabstandet angreifendens Zugmittel umfaßt, das andernends an einer Verlagerungseinrichtung zur Hubverstellung des Bremselementes senkrecht gegen den Fußboden aus seiner zurückgezogenen Grundstellung in seine gegen den Fußboden ausgefahrene Bremsstellung angreift.The invention solves this problem in that the actuator at least one arranged in the lower edge of the door in the mounted state, at one end on a door frame or on the floor of the pivot axis of the door spaced attacking traction means comprises the other end to a displacement device for the stroke adjustment of the brake element perpendicular to the Floor from his withdrawn basic position in his extended against the floor braking position attacks.

Durch das Vorsehen eines mit der in der Tür angeordneten Verlagerungseinrichtung zusammenwirkenden Zugmittels, beispielsweise eines Drahtoder Kunststoffseiles, wird bei einfachem Aufbau und einfacher Montagemöglichkeit des Bremselementes im Bereich der Türunterkante eine sichere Funktion der Bremse für die Türbewegung gewährleistet. Es muß lediglich eine Ausnehmung für die Verlagerungseinrichtung zur Hubverstellung des Bremselementes der Tür vorgesehen werden. Das Zugmittel kann wahlweise im Bereich zwischen Türunterkante und Fußboden oder in einer im Bereich der Türunterkante vorgesehenen Nut von der Verlagerungseinrichtung bis zu ihrem Angriffspunkt am Türstock oder Fußboden geführt werden. Es muß somit weder eine aufwendige Kulissenführung vorgesehen noch müssen die dafür erforderlichen aufwendigen Einstellarbeiten vorgenommen werden. Zum Einstellen des Bremsstoppers der erfindungsgemäßen Tür wird lediglich die Verlagerungseinrichtung in eine in der Tür vorgesehene Ausnehmung eingesetzt und das Zugmittel anschließend am gewünschten Befestigungspunkt am Fußboden oder am Türstock in Abhängigkeit des gewünschten Öffnungswinkels der Tür mit der erforderlichen Vorspannung befestigt.By providing a cooperating with the disposed in the door displacement device traction means, such as a wire or plastic rope, a safe function of the brake for the door movement is ensured with a simple design and easy mounting option of the brake element in the door lower edge. It must be provided only a recess for the displacement device for stroke adjustment of the brake element of the door. The traction device can either in the area between the lower edge of the door and floor or in the area of the lower door edge provided groove are guided by the displacement device to its point of attack on the door frame or floor. It must therefore be provided neither a complex slotted guide still have to be made the required elaborate adjustments. To set the brake stopper of the door according to the invention, only the displacement device is inserted into a recess provided in the door and the traction means then attached to the desired attachment point on the floor or on the door frame in dependence on the desired opening angle of the door with the required bias.

Besonders einfache Montageverhältnisse ergeben sich für das Bremselement, wenn dieses samt Verlagerungseinrichtung in einem Gehäuse im Bereich der Türunterkante angeordnet ist, da somit zur Montage bzw. zur Wartung lediglich das Gehäuse in eine im Bereich der Türunterkante vorgesehene Öffnung der Tür eingesetzt bzw. aus dieser herausgenommen werden muß. Das Gehäuse bildet dabei mit dem Bremselement vorzugsweise eine in eine beliebige Tür einsetzbare, vorfertigbare Baueinheit, die nach Anfertigen einer entsprechenden Ausnehmung jederzeit in eine bestehende Tür nachgerüstet werden kann.Particularly simple mounting conditions arise for the brake element, if this is arranged together with displacement device in a housing in the lower edge of the door, as thus used for mounting or maintenance, only the housing in an opening provided in the door lower edge opening of the door or removed from this must become. The housing forms with the brake element preferably a deployable in any door, prefabricated unit that can be retrofitted after making a corresponding recess at any time in an existing door.

Um stets eine sichere Rückführung des Bremselementes in seine Grundstellung zu gewährleisten, empfiehlt es sich, wenn das Bremselement mit Hilfe des Zugmittels gegen Federkraft in Richtung seiner gegen den Fußboden ausgefahrenen Bremsstellung verlagerbar ist.In order to always ensure a safe return of the brake element to its normal position, it is recommended that the braking element by means of the traction device against spring force in the direction of its extended against the floor braking position is displaced.

Eine einfache und wenig Platzbedarf aufweisende Konstruktion ergibt sich, wenn das Bremselement an einem um seine Verstellachse drehfest gelagerten, aber zur Hubverstellung axial im Gehäuse verschiebbaren Träger befestigt ist und die Verlagerungseinrichtung für den Träger einen den Träger in Abhängigkeit vom Öffnungswinkel der Tür gegen den Fußboden verlagernden Gewindetrieb umfaßt. Das Bremselement kann dabei im Träger um eine zur Türunterkante parallele Achse, vorzugsweise anschlagbegrenzt und gegen Federkraft schwenkverstellbar gelagert sein, wodurch sich einerseits eine sichere Bremswirkung für die Tür im Bremsbereich beim Öffnen der Tür ergibt und anderseits ein leichtes Schließen der Tür mit geringem Kraftaufwand jederzeit möglich ist. Dies ist insbesondere dann der Fall, wenn das Bremselement exzenterförmig ausgebildet ist.A simple and little space-requiring construction results when the brake element is mounted on a rotatably mounted about its adjustment axis, but axially displaceable for stroke adjustment in the housing carrier and the displacement device for the carrier displacing the carrier depending on the opening angle of the door against the floor Threaded drive includes. The brake element can be mounted pivotally adjustable in the carrier about an axis parallel to the door lower edge, preferably stop and against spring force, whereby on the one hand results in a secure braking action for the door in the braking area when opening the door and on the other hand easy closing of the door with little effort is possible at any time. This is especially the case when the brake element is formed eccentric.

Eine besonders vorteilhafte, weil platzsparende Konstruktion ergibt sich für den in der Tür angeordneten Bremsstopper, wenn der Gewindetrieb einen im Gehäuse um die Verstellachse des Trägers drehbar gelagerten, eine gewindeförmige Nut an seinem Umfang tragenden Drehkörper umfaßt, wobei die Nut mit einem vom Träger ausgebildeten Gewinde zusammenwirkt und das Zugmittel an einer Umfangsfläche des Drehkörpers seiltrommelartig angreift. Das in die Nut eingreifende Gewinde kann zu wenigstens einem Gewindezapfen reduziert sein.A particularly advantageous because space-saving construction results for the arranged in the door brake stop when the screw comprises a rotatably mounted in the housing about the adjustment axis of the support, a thread-shaped groove on its circumference supporting rotary body, wherein the groove formed with a thread formed by the carrier cooperates and the traction means acts on a peripheral surface of the rotary body like a rope drum. The engaging in the groove thread can be reduced to at least one threaded pin.

Eine erfindungsgemäße Tür 1 weist einen im Bodenbereich der Tür 1 angeordneten Bremsstopper 2 mit einem Bremselement 3 auf, das verstellbar in einem im Bereich der Türunterkante 4 angeordneten Gehäuse 5 in der Tür 1 geführt ist. Das Bremselement 3 ist dabei mittels eines durch die Türbewegung betätigten Stelltriebes in Form eines Zugmittels 6 (eines Seilzuges) aus einer bei geschlossener Tür zurückgezogenen Grundstellung (Fig. 4) in seine bei geöffneter Tür 1 die Türunterkante 4 überragende Bremsstellung vorbewegbar. Das Zugmittel 6 ist im Bereich der Türunterkante 4 in einer Nut 7 angeordnet und einerends am Türstock 8 mittels einer Schraube 9 von der Schwenkachse 10 der Tür 1 beabstandet befestigt und greift andernends an einer Verlagerungseinrichtung 11 zur Hubverstellung des Bremselementes 3 senkrecht gegen den Fußboden 12 aus seiner in die Tür 1 zurückgezogenen Grundstellung in seine gegen den Fußboden 12 ausgefahrene Bremsstellung an.A door 1 according to the invention has a brake stopper 2 arranged in the bottom region of the door 1 with a brake element 3 which is adjustably guided in the door 1 in a housing 5 arranged in the region of the door lower edge 4. The brake element 3 is in this case by means of an actuated by the door movement actuator in the form of a traction device 6 (a cable) from a retracted closed door closed basic position (Fig. 4) in his open door 1, the door lower edge 4 superior braking position vorbewegbar. The traction means 6 is arranged in the region of the door lower edge 4 in a groove 7 and at one end on the door frame 8 by a screw 9 spaced from the pivot axis 10 of the door 1 and engages the other end to a displacement device 11 for the stroke adjustment of the brake element 3 vertically against the floor 12 from its retracted into the door 1 basic position in his against the floor 12 extended braking position.

Das Bremselement 3 ist an einem um seine Verstellachse 14 drehfest gelagerten, aber zur Hubverstellung axial im Gehäuse 5 verschiebbaren Träger 13 befestigt. Die Verlagerungseinrichtung 11 für den Träger 13 weist einen den Träger 13 in Abhängigkeit vom Öffnungs- bzw. Schließwinkel der Tür 1 gegen den Fußboden 12 verlagernden Gewindetrieb auf. Der Gewindetrieb umfaßt einen im Gehäuse 5 um die Verstellachse 14 des Trägers 13 drehbar gelagerten, eine gewindeförmige Nut 17 an seinem Umfang tragenden Drehkörper 16, wobei die Nut 17 mit einem vom Träger 13 ausgebildeten Gewindezapfen 15 zusammenwirkt und das Zugmittel 6 an einem zylindrischen Abschnitt der Umfangsfläche 18 des Drehkörpers 16 seiltrommelartig angreift. Der Drehkörper 16 ist dabei gegenüber dem Gehäuse 5 mittels einer Spiralfeder 19 derart mittels Federkraft vorbelastet, daß die Spiralfeder 19 beim Schließen der Tür 1 für eine Rückstellung des Bremselementes 3 aus der Bremsstellung in seine Grundstellung sorgt und dabei das Zugmittel 6 am zylindrischen Abschnitt 18 des Drehkörpers 16 seiltrommelartig aufwickelt. Wird die Tür aus ihrer Schließstellung in die Offenstellung verschwenkt, wickelt sich das Zugmittel 6 vom zylindrischen Abschnitt 18 des Drehkörpers 16 ab und verdreht dabei den Drehkörper 16 im Gehäuse 5, wodurch der Träger 13 samt Bremselement 3 mittels des Gewindetriebes aus seiner in die Tür 1 zurückgezogenen Grundstellung in seine gegen den Fußboden 12 ausgefahrene Bremsstellung verlagert wird.The brake element 3 is fastened to a support 13 mounted rotatably about its adjustment axis 14 but axially displaceable in the housing 5 for stroke adjustment. The displacement device 11 for the carrier 13 has a the carrier 13 in response to the opening or closing angle of the door 1 against the floor 12 displacing screw drive. The screw drive comprises a rotatably mounted in the housing 5 about the adjustment axis 14 of the carrier 13, a thread-shaped groove 17 at its periphery supporting rotary body 16, wherein the groove 17 cooperates with a carrier 13 formed by the threaded pin 15 and the traction means 6 on a cylindrical portion of Peripheral surface 18 of the rotary body 16 rope drum-like attacks. The rotary body 16 is biased relative to the housing 5 by means of a coil spring 19 by spring force such that the coil spring 19 when closing the door 1 provides for a provision of the brake element 3 from the braking position to its normal position while the traction means 6 on the cylindrical portion 18 of Rotary body 16 wound up like a rope drum. If the door is pivoted from its closed position to the open position, the traction means 6 winds from the cylindrical portion 18 of the rotary body 16 and thereby rotates the rotary body 16 in the housing 5, whereby the carrier 13 together with the brake element 3 by means of the screw drive from his in the door. 1 retracted basic position is shifted in his against the floor 12 extended braking position.

Das Bremselement 3 ist im Träger 13 um eine zur Türunterkante 4 parallele Achse 20 anschlagbegrenzt gegen die Kraft einer Feder 21 schwenkverstellbar gelagert und gemäß dem Ausführungsbeispiel nach den Fig. 1 bis 4 exzenterförmig ausgebildet, wobei das Bremselement 3 in seiner Bremsstellung (Fig. 3) eine dem Fußboden 12 zugewandte Aufstandsfläche aufweist, die unter anderem dafür sorgt, daß die geöffnete Tür 1 sicher in ihrer Offenstellung gehalten wird und zum Schließen der Tür ein gewisser Kraftaufwand erforderlich ist. Eine Konstruktionsvariante eines Bremselementes 3 ist Fig. 5 zu entnehmen. Das Bremselement 3 könnte allerdings auch lediglich ein in den Träger 13 eingesetzter Bremsstoppel sein. Außerdem besteht die Möglichkeit mehrere Bremsstopper 2 in einer Tür 1 anzuordnen, was beispielsweise für den Fall besonders schwerer Türen von Interesse sein könnte.The brake element 3 is mounted pivotally adjustable in the support 13 about an axis parallel to the door lower edge 4 axis 20 against the force of a spring 21 and formed according to the embodiment of FIGS. 1 to 4 eccentric, wherein the brake element 3 in its braking position (Fig. 3) has a floor 12 facing contact patch, which ensures, inter alia, that the open door 1 is held securely in its open position and to close the door a certain amount of force is required. A design variant of a brake element 3 is shown in FIG. 5. However, the brake element 3 could also only one in the carrier 13 used brake stopper be. In addition, it is possible to arrange a plurality of brake stops 2 in a door 1, which could be of interest, for example in the case of particularly heavy doors.
