Abstract

The invention starts from a folding door. To make it possible to achieve high speeds while opening and closing the door, the invention provides that the door-forming sections (1) can be swivelled about a vertical axis (11) which is situated centrally with respect to their width extent, and the sections additionally consist essentially of plastic-foam panelling on either side. <IMAGE>

Description

Die Erfindung geht aus von einem an einer waagerechten Schiene aufgehängten Falttor, dessen Sektionen beim Falten um eine senkrechte Achse verschwenkbar sind.The invention is based on a folding door suspended on a horizontal rail, the sections of which can be pivoted about a vertical axis during folding.

Bei den bekannten Falttoren dieser Art fallen die Schwenkachsen der Sektionen im wesentlichen mit den Seitenkanten bzw. den Faltachsen der Sektionen zusammen. Hierdurch bedingt müssen insb. zum Öffnen des Tores bestimmte, vergleichsweise grosse Massenkräfte überwunden werden; die Sektionen müssen in ihrer Gesamtheit aus einer Ebene herausbewegt werden, die durch das geschlossene Tor bestimmt ist.In the known folding gates of this type, the pivot axes of the sections essentially coincide with the side edges or the folding axes of the sections. As a result, certain comparatively large mass forces must be overcome, in particular to open the gate; the sections as a whole must be moved out of a plane which is determined by the closed gate.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnten Tore so auszubilden, dass sie mit geringen Antriebskräften schnell geöffnet und geschlossen werden können. Es wird somit ein Schnellauftor angestrebt.The invention has for its object to design the gates mentioned in the introduction so that they can be opened and closed quickly with low driving forces. A fast-moving goal is therefore sought.

Zur Lösung dieser Aufgabe sind erfindungsgemäss die Sektionen um eine mittig in Bezug auf ihre Breite nerstreckung befindliche Achse verschwenkbar und sie bestehen im wesentlichen aus einem beidseitig paneeliertem Kunstschaum.To achieve this object, according to the invention, the sections can be pivoted about an axis located centrally in relation to their width and essentially consist of a synthetic foam paneled on both sides.

Aufgrund einer solchen Lagerung der Sektionen sind insb. zum Öffnen des Tores nur geringe Trägheitskräfte zu überwinden; dieser Effekt wird noch durch die erwähnte Bauweise der Sektionen unterstützt. Die Sektionen sind biegesteif, aber leicht. Daher gelingt es mit kleinen Antriebsmotoren, das Tor vergleichsweise schnell zu öffnen und zu schliessen.Due to such a storage of the sections, only small inertia forces have to be overcome, in particular to open the gate; this effect is further supported by the construction of the sections mentioned. The sections are rigid but light. Small drive motors therefore enable the gate to be opened and closed comparatively quickly.

Der Öffnungsvorgang des Tores kann noch dadurch beschleunigt werden, dass zwischen benachbarten Sektionen Druckfedern vorgesehen werden, die im geschlossenen Zustand des Tores gespannt sind und durch ein Entspannen zumindest die Losbrechkräfte des Tores überwinden. Beim Schliessen des Tores dienen diese Druckfedern als Bremsen; sie werden beim Schliessvorgang durch die abzubremsenden Massenkräfte gespannt und können zum Verschwenken der Sektionen beitragen, wenn das Tor geöffnet werden soll.The opening process of the door can be accelerated by providing compression springs between adjacent sections, which are tensioned when the door is closed and at least overcome the breakaway forces of the door by relaxing. When the gate closes, these compression springs act as brakes; they are tensioned during the closing process by the mass forces to be braked and can contribute to the pivoting of the sections when the gate is to be opened.

Die Sektionen 1 des Tores haben eine Breite 2 x X. Ihre Längsmittelachse ist mit 2 bezeichnet. Sie bestehen im übrigen aus einem hart eingestellten, spezifisch leichten Kunststoffschaum als Kernkörper 3, der vorne und hinten mit einer folien- bzw.- blechartigen Paneele 4 aus Aluminium festhaftend bedeckt ist. An den Enden der Sektionen 1 befinden sich u-förmige Profile 5 als Randeinfassung.The sections 1 of the gate have a width of 2 x X. Their longitudinal center axis is designated by 2. They also consist of a hard-set, specifically light plastic foam as the core body 3, which is covered at the front and rear with a foil or sheet-like panel 4 made of aluminum. At the ends of the sections 1 there are U-shaped profiles 5 as a border.

Benachbarte Sektionen 1 sind durch in Bezug auf die Längsmittelachse versetzte, also aussermittige Gelenkbolzen 6 mit Scharnierteilen 7 verbunden, und zwar wechselseitig, um in bekannter Weise eine Faltung der Sektionen 1 zu erreichen, wie dies in Fig. 1 gestrichelt wiedergegeben ist. An den einander zugekehrten Flächen 8 der Profile 5 sind hohl gehaltene Gummiprofile 9 befestigt, die im unverformten Zustand bei gefaltetem Tor stark ausgewölbt sind, beim Erreichen der Betriebsstellung ( Tor geschlossen ) stark vorgespannt werden, um so Energie zu speichern. Infolge der Aussermittigkeit der Gelenkbolzen 6 trachten die Gummiprofile 9 danach, die beiden Sektionen 1 im Sinne des Doppelpfeiles 1 zu trennen.Adjacent sections 1 are connected to hinge parts 7 by hinge parts 7 which are offset with respect to the longitudinal central axis, that is to say eccentric, in order to achieve a folding of the sections 1 in a known manner, as shown in dashed lines in FIG. 1. On the mutually facing surfaces 8 of the profiles 5, hollow rubber profiles 9 are fastened, which, in the undeformed state, are strongly arched when the door is folded, and are strongly pretensioned when the operating position (gate closed) is reached, so as to save energy. As a result of the eccentricity of the hinge pin 6, the rubber profiles 9 seek to separate the two sections 1 in the sense of the double arrow 1.

Die Sektionen 1 sind mittig, also auf halber Breite x durch einen senkrechten Bolzen 11 gehalten, der auch in der Längsmittelachse 2 liegt.Die Halterung erfolgt mittels angedeuteter Kugellager 12. Somit ist jede Sektion 1 um die durch den Bolzen 11 bestimmte senkrechte Achse verschwenkbar. Die Bolzen 11 sind je unten an einer waagerechten Halterung 16 befestigt, die oben mit drei Führungsrollen 13 (in den Ecken eines gleichseitigen Dreiecks gelegen ) versehen ist, welche mit ihrer umlaufenden Umfangsrille 13' in eine waagerechte Führungsschiene 14 bzw. in die seitlich spitz auslaufenden Ränder 15 dieser Schiene eingreifen. Die Führungsschiene 14 ist ihrerseits durch Haltebolzen 16' im Sturzbereich unter der Decke befestigt.The sections 1 are held in the center, that is to say half the width x, by a vertical bolt 11 which also lies in the longitudinal center axis 2. The mounting is carried out by means of indicated ball bearings 12. Each section 1 can thus be pivoted about the vertical axis determined by the bolt 11. The bolts 11 are each fastened at the bottom to a horizontal holder 16, which is provided at the top with three guide rollers 13 (located in the corners of an equilateral triangle), which with its circumferential circumferential groove 13 'into a horizontal guide rail 14 or into the laterally tapering end Engage edges 15 of this rail. The guide rail 14 is in turn fastened by retaining bolts 16 'in the lintel area under the ceiling.

Die Verschwenkung der Sektionen 1 erfolgt durch Hebelangriff auf eine Sektion 1 mittels Elektromotor. Es sind aber auch andere Antriebs- bzw. Verschwenkungsmöglichkeiten für die Sektionen 1 geeignet. Diese Verschwenkung erfolgt - unterstützt durch die vorgespannte Feder in Form der Gummiprofile 9 - augenblicklich; die Sektionen 1 haben infolge des erwähnten Aufbaus ein geringes Gewicht. Zudem kann eine schnelle Verschwenkung deshalb vollzogen werden, weil diese um die erwähnte Achse des Bolzens 11 geschieht.The sections 1 are pivoted by lever action on a section 1 by means of an electric motor. However, other drive or pivoting options for the sections 1 are also suitable. This pivoting takes place - supported by the prestressed spring in the form of the rubber profiles 9 - instantaneously; the sections 1 have a low weight due to the construction mentioned. In addition, a quick pivoting can be carried out because this takes place about the axis of the pin 11 mentioned.

Die Verschwenkung einer Sektion 1 führt infolge der gelenkigen Verbindung aller Sektionen 1 zu einer Öffnungs- bzw. einer Schliessbewegung des Tores. Da die Führung der Sektionen 1 infolge der Halterung 16 mit den drei Führungsrollen 13 sehr präzise und verkantungsfrei erfolgt, kann auf eine Führung und Halterung am unteren Ende der Sektionen 1 verzichtet werden. Diese sind also nur am oberen Ende mit Hilfe der Bolzen 11 geführt und aufgehängt.The pivoting of a section 1 leads to an opening or a closing movement of the gate as a result of the articulated connection of all sections 1. Since the sections 1 are guided very precisely and without tilting as a result of the holder 16 with the three guide rollers 13, one can Guide and bracket at the lower end of the sections 1 are dispensed with. These are therefore guided and suspended only at the upper end with the aid of the bolts 11.

Um den Vorgang des Torschliessens noch zu beschleunigen, ist eine aus Gummi oder einem anderen eigengedämpften Elastomer bestehende Zugfeder 2o vorgesehen. Mit einem Ende ist die sich im wesentlichen parallel zur Führungsschiene 14 erstreckende ( im gespannten Zustand ) Zugfeder 2o an der Seite der Toröffnung z.B. durch eine kleine Konsole 21 oder durch Befestigen an einem Bolzen 16' befestigt. Das andere Ende dieser Zugfeder 2o ist an dem der Konsole 21 zugekehrten, vorne liegenden Wagen bzw. an dem zugehörigen Bolzen 11' befestigt Die Zugfeder 2o ist so bemessen, dass sie im geöffneten Zustand des Tores etwa das 1.5 bis 3-fache ihrer nicht gedehnten Länge aufweist. Wird nunmehr unter diesen Voraussetzungen durch Einschalten des Antriebsmotors und Verschwenken der Sektionen 1 das Tor geöffnet, so unterstützt die Zugfeder 2o die Öffnungsbewegung, weil sie an dem vorne liegenden Wagen bzw. an der vorne liegenden Sektion 1 angreift. Mit der weiteren Öffnungsbewegung entspannt sich die Zugfeder 20. Bei geschlossenem Tor kann sie hinter dem Tor frei herabhängen oder durch Ringe od. dgl. gehalten sein.In order to accelerate the process of closing the door, a tension spring 2o made of rubber or another self-damped elastomer is provided. One end of the tension spring 2o, which extends essentially parallel to the guide rail 14 (in the tensioned state), is fastened to the side of the door opening, for example by a small bracket 21 or by fastening to a bolt 16 '. The other end of this tension spring 2o is fastened to the carriage lying at the front facing the bracket 21 or to the associated bolt 11 '. The tension spring 2o is dimensioned such that, when the door is open, it is about 1.5 to 3 times its unextended Has length. If the door is now opened under these conditions by switching on the drive motor and pivoting the sections 1, the tension spring 2o supports the opening movement because it engages the carriage lying in front or section 1 lying in front. The tension spring 2 0 relaxes with the further opening movement. When the gate is closed, it can hang freely behind the gate or be held by rings or the like.

Wird das Tor geöffnet, so wird die Zugfeder 2o zunehmend gespannt, wobei sie dämpfend wirkt und einen harten Anschlag in der Paketstellung verhindert.If the gate is opened, the tension spring 2o is increasingly tensioned, whereby it has a damping effect and prevents a hard stop in the package position.

Ggfs. kann auch die Konsole 21 weiter von der Toröffnung entfernt angeordnet sein, damit die Zugfeder 2o nicht zu stark durchhängt, wenn das Tor geöffnet ist.If necessary. the console 21 can also be arranged further away from the door opening so that the tension spring 2o does not sag too much when the door is open.

Im übrigen ist die Zugfeder 2o in Fig. 1 im gespannten Zustand gestrichelt und im entspannten Zustand gepunktet wiedergegeben.Otherwise, the tension spring 2o is dashed in Fig. 1 in the tensioned state and dotted in the relaxed state.
