Description

Die Erfindung bezieht sich auf eine Nothandkurbel für motorische Antriebe von Rolltoren, Rolladen, Deckengliedertoren od. dgl. mit einer federnd gelagerten Handkurbel, die ein Zahnrad trägt, das bei Bewegung der Handkurbel gegen die Wirkung einer Feder mit einem auf die Arbeitswelle wirkenden Getrieberad in kämmenden Kontakt bringbar ist.The invention relates to an emergency hand crank for motor drives of roller doors, roller shutters, overhead sectional doors or the like. With a spring-mounted hand crank that carries a gear that meshes with a gear wheel acting on the working shaft when the hand crank moves against the action of a spring Contact can be brought.

In der FR-A-1 270 577 wird eine solche Einrichtung beschrieben, die für den Einsatz mit einem üblichen Rottaden bestimmt ist, d. h. einer Vorrichtung, die relativ leicht ausgebildet ist. Handelt es sich bei den zu betätigenden Toren um große schwere Rolltore, treten erhebliche Gewichte auf und bei derartigen Einrichtungen hat sich herausgestellt, daß es nicht möglich ist, die beiden zusammenwirkenden Getriebeelemente zwischen der Nothandkurbel und der Antriebsachse als miteinander kämmende Kegelräder zu gestalten, wie dies bei der bekannten Einrichtung der Fall ist. In solchen Fällen ist vielmehr die Kraft, die bestrebt ist, das mit der Nothandkurbel verbundene Getriebeelement wieder zurückzudrücken, so groß, daß es für eine normale Bedienungsperson nicht möglich ist, die Nothandkurbel zu betätigen, sondern der stets und ständig aufzubringenden Druck oder der entsprechende Zug, der einmal den Druck der Feder, zum andern aber den durch die Kegelverzahnung auftretenden Druck überwinden muß, ist so groß, daß eine ordnungsgemäße Betätigung nicht möglich ist.In FR-A-1 270 577 such a device is described, which is intended for use with a conventional Rottaden, i. H. a device that is relatively light. If the gates to be operated are large, heavy roller gates, considerable weights occur and it has been found in such devices that it is not possible to design the two cooperating gear elements between the emergency hand crank and the drive axis as meshing bevel gears, as is the case with this is the case with the known device. In such cases, the force that tends to push back the gear element connected to the emergency hand crank is so great that it is not possible for a normal operator to actuate the emergency hand crank, but rather the pressure that is always to be applied or the corresponding pull , which on the one hand has to overcome the pressure of the spring, and on the other hand the pressure arising from the bevel gear, is so great that proper operation is not possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Getriebeverbindung zwischen der Nothandkurbel und der Arbeitswelle eines motorischen Antriebes von schweren Rolltoren oder Dekkengliedertoren zu schaffen, die unabhängig von dem Gewicht des zu betätigenden Öffnungsabschlusses eine einwandfreie und leichte Betätigung der Nothandkurbel gestattet.The invention has for its object to provide a gear connection between the emergency hand crank and the working shaft of a motor drive of heavy rolling gates or ceiling sectional doors, which allows a perfect and easy operation of the emergency hand crank regardless of the weight of the opening closure to be operated.

Diese der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß das auf der Handkurbel gelagerte Zahnrad ein Stirnrad mit parallel zur Handkurbelachse verlaufenden Mantellinien ist und das mit der Arbeitswelle mittelbar verbundene Getrieberad als Kronenrad ausgebildet ist, dessen Zahnmantellinien in einer zur Kronenradachse senkrechten Ebene liegen.This object of the invention is achieved in that the gear wheel mounted on the hand crank is a spur gear with surface lines running parallel to the hand crank axis and the gear wheel indirectly connected to the working shaft is designed as a crown wheel, the tooth surface lines of which lie in a plane perpendicular to the crown wheel axis.

Gemäß einer ersten Ausführungsform der Erfindung wird dabei so vorgegangen, daß das Kronenrad am freien Ende der Motornotachse angeordnet ist.According to a first embodiment of the invention, the crown gear is arranged at the free end of the emergency motor axis.

Gemäß einer anderen Ausführungsform der Erfindung wird so vorgegangen, daß das Kronenrad auf einer Schneckenwelle angeordnet ist, die mit einem Schneckenrad der Arbeitswelle kämmt, d. h. der Welle, auf der das Rolltor, das Deckengliedertor oder der Rolladen od. dgl. aufgewickelt ist.According to another embodiment of the invention, the procedure is such that the crown wheel is arranged on a worm shaft which meshes with a worm wheel of the working shaft, i. H. the shaft on which the roller door, the overhead sectional door or the roller shutter or the like is wound.

Bei der ersten Ausführungsform wird eine leicht herstellbare einfache Verbindung geschaffen, während bei der zweiten Ausführungsform die räumlichen Verhältnisse niedrig gehalten werden können und insbesondere dadurch, daß ein unmittelbares Einwirken des Stirnrades auf die Schneckenwelle Schwingungen innerhalb der Getriebeverbindung ausgeschaltet werden. Außerdem ist das Übersetzungsverhältnis bei dieser Anordnung für die Nothandkurbel verbessert, da das Kronenrad direkt auf die Schneckenwelle wirkt.In the first embodiment, an easy to manufacture simple connection is created, while in the second embodiment the spatial conditions can be kept low and in particular by the fact that a direct action of the spur gear on the worm shaft vibrations within the transmission connection are eliminated. In addition, the transmission ratio is improved in this arrangement for the emergency hand crank, since the crown gear acts directly on the worm shaft.

Bevor der Kontakt zwischen dem Kronenrad und dem Stirnrad hergestellt wird, ist sichergestellt, daß über einen am Langhandkurbelzapfen vorgesehenen Auflaufnocken ein Unterbrecherkontakt betätigt wird, der die Stromzufuhr zum Motor stillsetzt, so daß sichergestellt ist, daß dann, wenn ein kämmender Eingriff zwischen Stirnrad und Kronenrad erfolgt, der Motor nicht motorisch angetrieben werden kann, so daß dann der Antrieb des Motors ausschließlich über den Langhandkurbelzapfen erfolgt.Before the contact between the crown gear and the spur gear is made, it is ensured that an interrupter contact is actuated via a stop cam provided on the long-hand crank pin, which shuts off the power supply to the motor, so that it is ensured that if there is a meshing engagement between the spur gear and the crown gear takes place, the motor can not be driven by a motor, so that the motor is then driven exclusively via the long-hand crank pin.

Ausführungsbeispiele der Erfindung werden nachfolgend an Hand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei in

  • Fig. 1 eine erste Ausführungsform der Erfindung, wobei die Notlanghandkurbel auf die Motornotachse wirkt und in
  • Fig. 2 eine zweite Ausführungsform der Erfindung, bei der die Notlanghandkurbel unmittelbar auf die Schneckenwelle, die die Arbeitswelle antreibt, wirkt.
Embodiments of the invention are explained below with reference to the drawings. The drawings show in
  • Fig. 1 shows a first embodiment of the invention, wherein the emergency long-hand crank acts on the engine emergency axis and in
  • Fig. 2 shows a second embodiment of the invention, in which the emergency long hand crank acts directly on the worm shaft that drives the working shaft.

In Fig. 1 ist mit 1 der eigentliche Motor für den Antrieb, beispielsweise eines Rolladens oder eines Deckengliedertores bezeichnet. Der Motor ist innerhalb einer Schutzvorrichtung 2 angeordnet und weist eine sogenannte Motornotachse 3 auf, die bei dem dargestellten Ausführungsbeispiel und in Übereinstimmung mit dem erfindungsgemäßen Vorschlag an ihrem Ende ein Kronenrad 4 trägt, dessen Zahnmantellinien in einer zur Kronenradachse senkrechten Ebene liegen. Das Kronenrad 4 liegt bereits außerhalb der Schutzvorrichtung 2 für den Motor, und zwar an einem an die Schutzvorrichtung 2 anzuflanschenden Gehäuse 5, das den gesamten Notlanghandkurbeltrieb aufnimmt.In Fig. 1, 1 is the actual motor for the drive, for example a roller shutter or a sectional door. The motor is arranged within a protective device 2 and has a so-called motor emergency axis 3, which in the illustrated embodiment and in accordance with the proposal according to the invention carries at its end a crown wheel 4, the tooth surface lines of which lie in a plane perpendicular to the crown wheel axis. The crown wheel 4 is already outside the protective device 2 for the motor, specifically on a housing 5 to be flanged onto the protective device 2, which accommodates the entire emergency long-hand crank drive.

In diesem Gehäuse ist gegen die Kraft einer Wendeldeder 6 gelagert ein Langhandkurbelzapfen 14 angeordnet, der gegen die Kraft der Wendelfeder 6 nach unten bewegbar ist, wenn eine entsprechende Langhandkurbel angeschlossen wird. Die Wendelfeder 6 ist dabei in einem haubenförmigen Sicherheitsgehäuse 7 angeordnet, das über einen entsprechenden Bolzen 8 an dem Kurbelzapfen festgelegt ist. Die Wendelfeder 6 stützt sich andererseits an der Unterseite des Kurbelgehäuses 5 ab.In this housing, a long-hand crank pin 14 is arranged against the force of a helical spring 6 and can be moved downward against the force of the helical spring 6 when a corresponding long-hand crank is connected. The helical spring 6 is arranged in a hood-shaped safety housing 7, which is fixed to the crank pin via a corresponding bolt 8. The helical spring 6, on the other hand, is supported on the underside of the crankcase 5.

Am oberen Ende trägt der Langhandkurbelzapfen ein Stirnrad 9 mit parallel zur Handkurbelachse verlaufenden Mantellinien, das, wenn der Langhandkurbelzapfen 14 gegen die Wirkung der Wendelfeder 6 nach unten bewegt wird, mit dem Kronenrad 4 in kämmendem Kontakt bringbar ist.At the upper end, the long-hand crank pin carries a spur gear 9 with surface lines running parallel to the hand crank axis, which, when the long-hand crank pin 14 is moved downward against the action of the helical spring 6, is in meshing contact with the crown wheel 4 is feasible.

Bevor dieser Kontakt stattfindet, läuft ein am Langhandkurbelzapfen 14 vorgesehener Aufnokken 10 an einem Schalter 11 eines Unterbrechers 12 auf und bewirkt dadurch, daß die Stromzufuhr zum Motor 1 unterbrochen wird. Hierzu ist der Unterbrecher 12 unmittelbar in die Stromzufuhr des Motors eingeschaltet, was aus der Zeichnung nicht zu ersehen ist und aus Übersichtlichkeitsgründen auch nicht dargestellt werden muß.Before this contact takes place, a catch 10 provided on the long-hand crank pin 14 runs on a switch 11 of an interrupter 12 and thereby causes the power supply to the engine 1 to be interrupted. For this purpose, the interrupter 12 is switched directly into the power supply to the motor, which cannot be seen from the drawing and, for reasons of clarity, also does not have to be shown.

In besonders vorteilhafter Weise ist dabei vorgesehen, daß der Auflaufnocken 10 im Bereich des Langhandkurbelzapfens so angeordnet ist, daß er in der vom Kronenrad 4 umlaufenden Bahn gelagert ist und damit raumgünstig untergebracht werden kann, aber ein genügender Raum für die störungsfreie Bewegung des Langhandkurbelzapfens zur Verfügung steht.In a particularly advantageous manner, it is provided that the overrun cam 10 is arranged in the region of the long-hand crank pin in such a way that it is mounted in the path encircling the crown wheel 4 and can therefore be accommodated in a space-saving manner, but sufficient space is available for the trouble-free movement of the long-hand crank pin stands.

Es ist erkennbar, daß bei der erfindungsgemäßen Einrichtung bei Betätigen des Langhandkurbelzapfens 14, d. h. also Bewegungen des Kurbelzapfens nach unten gegen die Kraft der Wendelfeder 6, das Stirnrad 9 in einfachster Weise mit dem Kronenrad 4 in Kontakt bringbar ist, wobei gleichzeitig die Stromzufuhr zum Motor stillgesetzt ist und nunmehr über den Langhandkurbelzapfen und die daran anschließende Langhandkurbel das Betätigen der Motornotachse 3 möglich ist.It can be seen that in the device according to the invention when the long-hand crank pin 14, d. H. So movements of the crank pin down against the force of the helical spring 6, the spur gear 9 can be brought into contact with the crown wheel 4 in the simplest manner, the power supply to the engine being stopped at the same time and now actuating the emergency engine axis via the long-hand crank pin and the subsequent long-hand crank 3 is possible.

Bei der in Fig. 2 dargestellten Ausführungsform ist der Langhandkurbelzapfen mit 114 bezeichnet, der Auflaufnocken trägt das Bezugszeichen 100, das Stirnrad das Bezugszeichen 19 und die auch bei dieser Ausführungsform erforderliche Wendelfeder das Bezugszeichen 16. Der Motor ist bei 1 erkennbar und die Motorabtriebswelle wirkt auf ein Zahnrad 27, das mit einem auf einer Schneckenwelle 25 angeordneten Zahnrad 28 kämmt, wobei dieses Zahnrad 28 das Kronenrad 24 trägt. Die Schneckenwelle 25 treibt über ein entsprechendes Getriebe die eigentliche Arbeitswelle 26 an, die in der Zeichnung in der Front erkennbar ist.In the embodiment shown in FIG. 2, the long-hand crank pin is designated by 114, the overrun cam bears the reference number 100, the spur gear has the reference number 19 and the helical spring also required in this embodiment has the reference number 16. The motor can be seen at 1 and the motor output shaft acts a gear 27 which meshes with a gear 28 arranged on a worm shaft 25, this gear 28 carrying the crown gear 24. The worm shaft 25 drives the actual working shaft 26 via a corresponding gear, which can be seen in the drawing in the front.

Im Gegensatz zu der in Fig. 1 dargestellten Ausführungsform baut die Ausführungsform gemäß Fig. 2 wesentlich kleiner und raumsparender, und außerdem wirkt das vom Stirnrad 9 betätigte Kronenrad 24 unmittelbar auf die Hauptantriebswelle für die Arbeitswelle, so daß irgendwelche Vibrationen oder sonstige schädliche Übertragungen zwischen dem Nottrieb und der Arbeitswelle ausgeschaltet sind und das Übersetzungsverhältnis verbessert ist.In contrast to the embodiment shown in FIG. 1, the embodiment according to FIG. 2 builds much smaller and space-saving, and also the crown gear 24 actuated by the spur gear 9 acts directly on the main drive shaft for the working shaft, so that any vibrations or other harmful transmissions between the Emergency drive and the working shaft are switched off and the gear ratio is improved.
