Description

Die Erfindung betrifft ein Schnellauftor mit einer im Bereich des oberen Endes von Seitenprofilen gelagerten Wickelwelle, die durch einen Getriebe-Brems-Motor antreibbar und auf die das mit einem unteren aussteifenden Abschlußprofil versehene Torblatt aufwickelbar ist, mit einer im Bereich der unteren Kante des Abschlußprofils vorgesehenen Schalteinrichtung, die bei ihrer Betätigung die Bremse einfallen läßt, und mit einem Endschalter, der die Bremse einfallen läßt, wenn das Abschlußprofil den Boden - bereich erreicht hat.The invention relates to a high-speed door with a winding shaft mounted in the region of the upper end of side profiles, which can be driven by a gear-brake motor and onto which the door leaf provided with a lower stiffening end profile can be wound, with a provided in the region of the lower edge of the end profile Switching device which, when actuated, engages the brake and with a limit switch, which engages the brake when the end profile has reached the floor area.

Schnellauftore dieser Art sind in unterschiedlichen Ausführungsformen bekannt. Sie bestehen aus einem auf die Wickelwelle, vorzugsweise auf eine mit dieser verbundenen Wickeltrommel, aufwikkelbaren und von dieser abwickelbaren, das Torblatt bildenden Behang aus flexiblem Material, vorzugsweise durchsichtigem Kunststoff. Zur Aussteifung ist das untere Ende des Torblattes mit einem schwertförmigen Abschlußprofil versehen, dessen Enden in den Seitenprofilen, die auch durch die Türzarge gebildet sein können, geführt sind. Beim Öffnen und Schließen fährt das Abschlußprofil, das üblicherweise aus einem Aluminiumprofil besteht, mit relativ großer Geschwindigkeit nach oben und unten, wobei das während des Schließens nach unten fahrende Abschlußprofil mit großer Wucht auf unter diesem befindliche Personen oder Gegenstände mit entsprechender Verletzungs- und Beschädigungsgefahrtreffen kann.High-speed doors of this type are known in different embodiments. They consist of a curtain made of flexible material, preferably transparent plastic, which can be wound up and unwound from the winding shaft, preferably onto a winding drum connected to it, and can be unwound from it. For bracing, the lower end of the door leaf is provided with a sword-shaped end profile, the ends of which are guided in the side profiles, which can also be formed by the door frame. When opening and closing, the end profile, which usually consists of an aluminum profile, moves up and down at a relatively high speed, and the end profile, which moves downward during closing, can hit people or objects located underneath it with a corresponding risk of injury and damage .

Um diese Verletzungs- und Beschädigungsgefahr auszuschließen, sind die Abschlußprofile im Bereich ihrer unteren Kanten mit Sicherheitsleisten versehen, die Schalteinrichtungen aufweisen, die bei ihrer Betätigung die Motorbremse, üblicherweise durch Abschalten des Motorstroms, einfallen lassen. Aufgrund des Gewichts und insbesondere der kinetischen Energie des Torblatts und des Abschlußprofils ergibt sich abgesehen von der Schaltverzögerung ein unvermeidbarer Bremsweg, der einen besonderen Gefahrenbereich darstellt. Aus diesem Grunde bestehen die Sicherheitsleisten üblicherwiese aus Profilen, vorzugsweise Hohlprofilen, aus elastomerem Material, deren unteren Kantenbereiche mit den Schalteinrichtungen versehen sind, die bekannter Art sind und beispielsweise aus Kontaktlitzen oder Druckwellenschaltern bestehen können.In order to rule out this risk of injury and damage, the end profiles are provided in the area of their lower edges with safety strips which have switching devices which, when actuated, cause the motor brake to engage, usually by switching off the motor current. Due to the weight and in particular the kinetic energy of the door leaf and the end profile, apart from the switching delay, there is an unavoidable braking distance, which represents a special danger area. For this reason, the safety strips usually consist of profiles, preferably hollow profiles, made of elastomeric material, the lower edge regions of which are provided with the switching devices, which are of a known type and can consist, for example, of contact strands or pressure wave switches.

AusEP-A-0 143 712 ist eine aus einem Hohlprofil aus elastomerem Material bestehende Sicherheitsleiste bekannt, deren quer verlaufenden Kanäle durch Schläuche mit einem druckempfindlichen Schalter verbunden sind, der die Motorbremse betätigt, wenn der Druck in den Schläuchen durch Zusammendrücken der Sicherheitsleiste ansteigt.From EP-A-0 143 712 a safety strip consisting of a hollow profile made of elastomeric material is known, the transverse channels of which are connected by hoses to a pressure-sensitive switch which actuates the motor brake when the pressure in the hoses increases by compressing the safety strip.

Aus DE-U-8 615 042 ist eine aus einem Rohr aus elastomerem Material bestehende Sicherheitsleiste eine Abschlußprofils bekannt, der an einer Seite mit einer Lampe und an der anderen Seite mit einem lichtempfindlichen Widerstand versehen ist, so daß ein die Motorbremse betätigender Schaltimpuls erzeugt werden kann, wenn das Rohr durch Auftreffen auf ein Hindernis in der Weise zusammengedrückt wird, daß der lichtempfindliche Widerstand abgedunkelt wird.From DE-U-8 615 042 a safety bar consisting of a tube made of an elastomeric material is known as an end profile, which is provided on one side with a lamp and on the other side with a light-sensitive resistor, so that a switching pulse actuating the motor brake is generated can, if the tube is compressed by hitting an obstacle in such a way that the photosensitive resistance is darkened.

Bei diesen aus elastomerem Material bestehenden Sicherheitsleisten, die in ihrem unteren Kantenbereich mit Schalteinrichtungen versehen sind, ist aber nur dann eine hinreichende Sicherheit gengen Verletzungen und Beschädigungen gegeben, wenn deren Verformungsbereich dem Nachlaufweg von der Betätigung der Schalteinrichtung bis zum vollständigen Abbremsen des Abschlußprofils entspricht. Da ein relativ langer Nachlaufweg, der der Schaltverzögerung und dem Bremsweg entspricht, unvermeiddar ist, bedeutet dies, daß hole und damit teure Sicherheitsleisten aus profiliertem elastomerem Material verwendet werden müssen, deren Verformungsweg in den seltensten Fällen jedoch größer ist als der Nachlaufweg bis zum vollständigen Abbremsen des Abschlußprofils.In these safety strips made of elastomeric material, which are provided with switching devices in their lower edge area, there is only sufficient security against injuries and damage if their deformation area corresponds to the overtravel from the actuation of the switching device to the complete braking of the end profile. Since a relatively long overtravel, which corresponds to the switching delay and the braking distance, is unavoidable, this means that perforated and therefore expensive safety strips made of profiled elastomeric material must be used, the deformation path of which, however, is rarely greater than the overtravel distance until the brakes are fully applied of the final profile.

Ein weiterer Nachteil bekannter, aus profiliertem elastomerem Material bestehender Sicherheitsleisten besteht abgesehen von der unvermeidbaren Betätigungskraft und der sich aus deren Verformung ergebenden Widerstandskraft darin, daß sich entsprechend der Auftreffrichtung Schaltverzögerungen oder sogar Schaltausfälle ergeben können.Another disadvantage of known safety strips made of profiled elastomeric material, apart from the unavoidable actuation force and the resistance force resulting from their deformation, is that switching delays or even switching failures can occur depending on the direction of impact.

Aus der älteren aber nicht vorveröffentlichten WO 88/02804 ist ein Schnellauftor der eingangs angegebener Art bekannt, bei dem die Schalteinrichtung aus einer Lichtschranke besteht, deren Geber-und Aufnehmerelemente beidseits des Abschlußprofils in einem Abstand, der dem Bremsweg entspricht, unterhalb von diesem an mit Abstützsockeln versehenen blockartigen Abwinkelungen von Stempeln in der Bewegungsebene des Abschlußprofils angeordnet sind, so daß sich das Abschlußprofil in der Schließstellung des Tores auf diesen blockartigen Abwinkelungen abstützt. Das Abschlußprofil ist mit einem Abdichtstreifen versehen, der den Boden berühren kann.From the older but not pre-published WO 88/02804 a high-speed door of the type mentioned is known, in which the switching device consists of a light barrier, the transmitter and sensor elements on both sides of the end profile at a distance that corresponds to the braking distance, below this with Block-like bends of plungers provided with support bases are arranged in the plane of movement of the end profile, so that the end profile is supported on these block-like bends in the closed position of the door. The end profile is provided with a sealing strip that can touch the floor.

Aufgabe der Erfindung ist es daher, ein Schnellauftor der eingangs angegebenen Art zu schaffen, das mit einer Schalteinrichtung versehen ist, die dessen Abschlußprofil mit großer Sicherheit innerhalb eines Nachlaufweges zum Stillstand bringt, der die Verletzung von Personen und/oder Beschädigung von Gegenständen ausschließt.The object of the invention is therefore to provide a high-speed door of the type mentioned, which is provided with a switching device which brings its end profile to a standstill with great certainty within a caster path, which excludes the injury of people and / or damage to objects.

Erfindungsgemäß wird diese Aufgabe durch die Merkmal des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the feature of patent claim 1.

Bei dem erfindungsgemäßen Schnellauftor wird somit die Motorbremse berührungslos durch die aus einer Lichtschranke bestehende Schalteinrichtung betätigt, so daß ein Auftreffen einer Sicherheitsleiste des Abschlußprofils auf Personen oder Gegenstände, das erst den Schaltimpuls erzeugt, mit dessen nachteiligen Folgen vermieden ist. Die Lichtschranke läßt sich in einfacher Weise in einem Abstand unterhalb des Abschlußprofils anordnen, der größer ist als der sich aus der Schaltverzögerung und dem Bremsweg ergebende Nachlauf.In the high-speed door according to the invention, the motor brake is thus actuated in a contactless manner by the switching device consisting of a light barrier, so that an impact of a safety strip of the end profile on persons or objects, which only generates the switching pulse, with the latter adverse consequences is avoided. The light barrier can be arranged in a simple manner at a distance below the end profile which is greater than the run-on resulting from the switching delay and the braking distance.

Stoßen die Stempel beim Herabfahren des Abschlußprofils auf den Boden, tauchen diese teleskopartig in ihre Führungen ein, sodaßsich dasAbschlußprofil behinderungsfrei unmittelbar auf dem Boden abstützen kann, wobei natürlich das Abschlußprofil zusätzlich auch mit einer puffernden unteren Kante aus einem elastomeren Material versehen sein kann, die aber nur noch Dichtungsfunktion zu haben braucht und keine Schalt- und Sicherheitsfunktion mehr.If the punches hit the floor when the end profile is lowered, they dip into their guides telescopically, so that the end profile can be supported directly on the floor without hindrance, although the end profile can of course also be provided with a buffering lower edge made of an elastomeric material, but this only needs to have a sealing function and no more switching and safety functions.

Die die Geber- und Nehmerelemente der Lichtschranke tragenden Stempel können unter Schwerkraftwirkung ausfahrbar und einschiebbar sein. Zweckmäßigerweise sind die Stempel aber in Richtung auf ihre ausgefahrene Stellung durch Federn beaufschlagt. Dadurch wird nicht nur die Funktionssicherheit erhöht, sondern die Stempel können auch leichter, d.h. mit geringerer Masse, ausgeführt werden, so daß diese mit geringerer Stoßbeanspruchung eingeschoben werden können.The stamps carrying the transmitter and receiver elements of the light barrier can be extended and inserted under the action of gravity. Advantageously, the stamps are acted upon by springs in the direction of their extended position. This not only increases functional reliability, but the stamps can also be lighter, i.e. with lower mass, so that they can be inserted with less impact.

Der Ausfahr- und Einschubweg der Stempel o.dgl. kann durch Anschläge begrenzt sein. Zweckmäßigerweise ist die Einschublänge der Stempel o.dgl. in den Führungen der Abschlußleiste einstellbar, so daß sich der Schaltzeitpunkt in der gewünschten Weise auf den jeweiligen Nachlaufweg des Abschlußprofils einstellen läßt.The extension and insertion path of the stamp or the like. can be limited by stops. The insertion length of the stamp or the like is expediently. adjustable in the guides of the end strip, so that the switching time can be adjusted in the desired manner to the respective overtravel of the end profile.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur eine Draufsicht auf den unteren Bereich eines Schnellauftores schematisch dargestellt ist, näher erläutert.An embodiment of the invention is explained below with reference to the drawing, in the single figure of which a plan view of the lower area of a high-speed door is schematically shown.

In vertikal verlaufenden schlitzartigen Führungen der Seitenprofile 1, 2 des Schnellauftores sind seitliche schwertartige Fortsätze 4, 5 des aus Aluminium bestehenden Abschlußprofils 6 geführt.

In the upper area of the end profiles 1, 2, the winding shaft is mounted in a known and therefore not described manner, which is driven in a known manner by a geared brake motor. The end profiles 1, 2 are fastened in a known manner in a gate opening or at the edge region thereof and are supported on the floor either directly or via base plates.

Das Abschlußprofil 6 ist in bekannter Weise an dem unteren Rand des flexiblen Torblattes 7 befestigt.The end profile 6 is attached to the lower edge of the flexible door leaf 7 in a known manner.

Das Abschlußprofil 6 ist im Bereich seiner beiden Enden mit zu den Seitenprofilen 1, 2 parallelen Führungen, 8, 9 versehen, in denen Stempel 10, 11 einfahrbar und ausschiebbar geführt sind. Die Stempel 10, 11 sind in den Führungen 8, 9 durch Druckfedern in Ausschubrichtung belastet. Der Ein- und Ausschubweg der Stempel 10, 11 in den Führungen 8, 9 ist durch nicht dargestellte Anschläge begrenzt. Dabei ist es im Grunde nur erforderlich, den Ausschubweg durch Anschläge zu begrenzen, damit die Stempel 10, 11 aus ihren Führungen nicht herausfahren, da die Stempel beim Herabfahren des Abschlußprofils 6 vollständig in die Führungen eingedrückt werden sollen, so daß insoweit keine Anschläge erforderlich sind.The end profile 6 is provided in the region of its two ends with parallel to the side profiles 1, 2 guides 8, 9, in which stamps 10, 11 are guided retractable and extendable. The punches 10, 11 are loaded in the guides 8, 9 by compression springs in the direction of extension. The insertion and extension path of the punches 10, 11 in the guides 8, 9 is limited by stops, not shown. It is basically only necessary to limit the extension path by stops so that the stamps 10, 11 do not move out of their guides, since the stamps are to be pressed completely into the guides when the end profile 6 is lowered, so that no stops are required .

Die Stempel 10, 11 sind mit Geber- und Aufnehmerelementen 12, 13 versehen, die eine Lichtschranke bilden. Dabei weist die die Geber- und Nehmerelemente 12, 13 verbindende optische Achse von der Unterkante des Abschlußprofils 6 einen Abstand x auf, der gleich oder vorzugsweise größer ist als der Nachlaufweg des Abschlußprofils nach Betätigung der Lichtschranke bis zum Stillstand des Abschlußprofils.The stamps 10, 11 are provided with transmitter and sensor elements 12, 13, which form a light barrier. The optical axis connecting the transmitter and slave elements 12, 13 has a distance x from the lower edge of the end profile 6 which is equal to or preferably greater than the overtravel of the end profile after actuation of the light barrier until the end profile has come to a standstill.

Den Führungen 8,9 entsprechende Führungen können auch in den seitlichen schwertartigen Fortsätzen 4,5 angeordnet sein. Diese Ausgestaltung hat den Vorteil, daß dann die in den Führungen geführten und in diese einschiebbaren Stempel 10,11 weiter seitlich nach außen verlagert und auch in den Seitenprofilen, die üblicherweise als Hohlprofile ausgebildet sind, angeordnet werden können. Dadurch können die Stempel zusätzlich geschützt werden. Die die Geber- und Nehmerelemente 12,13 verbindende optische Achse kann dann durch Schlitze in den Seitenprofilen verlaufen.Guides corresponding to the guides 8, 9 can also be arranged in the lateral sword-like extensions 4,5. This configuration has the advantage that the punches 10, 11 which are guided in the guides and can be pushed into them can be further displaced laterally outwards and also be arranged in the side profiles, which are usually designed as hollow profiles. This allows the stamps to be additionally protected. The optical axis connecting the transmitter and receiver elements 12, 13 can then run through slots in the side profiles.

Es ist auch möglich, die Stempel 10,11 starr mit dem Abschlußprofil oder den seitlichen schwertartigen Fortsätzen 4,5 zu verbinden und diese sodann in entsprechende Ausnehmungen am Boden eintauchen zu lassen. Diese Ausführung setzt aber voraus, daß die Ausnehmungen nicht verstopft werden können, was vermutlich nicht in allen Fällen mit Sicherheit ausgeschlossen werden kann.It is also possible to rigidly connect the punches 10, 11 to the end profile or the lateral sword-like extensions 4, 5 and then to immerse them in corresponding recesses on the floor. However, this embodiment assumes that the recesses cannot be blocked, which probably cannot be excluded with certainty in all cases.

Die Geber- und Nehmerelemente sind in nicht dargestellter Weise durch Leitungen mit einer Steuereinrichtung verbunden. Diese Leitungen sind in bekannter Weise flexibel ausgebildet, damit diese den Bewegungen der Stempel 11, 12 und auch des Abschlußprofils folgen können.The transmitter and slave elements are connected in a manner not shown by lines to a control device. These lines are flexible in a known manner so that they can follow the movements of the stamp 11, 12 and also the end profile.

Weiterhin ist in bekannter Weise ein Endschalter vorgesehen, der die Bremse einfallen läßt, wenn das Abschlußprofil den Bodenbereich erreicht hat.Furthermore, a limit switch is provided in a known manner, which can apply the brake when the end profile has reached the floor area.

Bei dem beschriebenen Schnellauftor fällt die Motorbremse ein, wenn die aus den Geber- und Nehmerelementen 12, 13 bestehende Lichtschranke ein Schaltsignal liefert, so daß das Abschlußprofil durch die berührungslose Abschaltung zum Stillstand kommt, bevor die Person oder der Gegenstand von dem Abschlußprofil getroffen wird, die das Schaltsignal ausgelöst haben.In the high-speed door described, the motor brake is applied when the light barrier consisting of the transmitter and receiver elements 12, 13 delivers a switching signal so that the end profile comes to a standstill due to the contactless shutdown before the person or object is hit by the end profile. that triggered the switching signal.
