Definitions
- the invention relates to an emergency long-hand crank for motor drives for gates, roller shutters, overhead sectional doors or the like.
- Such emergency long-hand cranks are known today and usually make contact with the so-called engine emergency axis in that a slip clutch or claw clutch is arranged between the long-hand crank pin and the engine emergency axis. While the slip clutch does not provide the desired and desired safety, the claw clutch is a construction which is too complex, so that it cannot be produced in a desirable, inexpensive manner and in large numbers.
- the invention has for its object to provide an emergency long crank for the actual work shaft, which is inexpensive to manufacture and also retrospectively Lich can be easily added to existing facilities.
- This object on which the invention is based is achieved by a crown wheel connected directly or indirectly to the working shaft and a resilient mounting of a long-hand crank pin, at the end region of which a spur gear is arranged which, when the long-hand crank pin moves against the action of the spring of a spring bearing, in meshing contact with the crown wheel is feasible.
- the crown gear is arranged at the free end of the emergency motor axis.
- the procedure is such that the crown wheel is arranged on a worm shaft which meshes with a worm wheel of the working shaft.
- the spatial conditions can be kept low and in particular in that a direct action of the spur gear on the worm shaft vibrations within the gearbox binding can be switched off.
- the transmission ratio is improved in this arrangement for the emergency crank, since the crown gear acts directly on the worm shaft.
- 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 exemplary embodiment shown and in accordance with the proposal according to the invention, carries a crown wheel 4 at its end.
- 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.
- a long-hand crank pin 1 4 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 attached is closed.
- 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.
- the long-hand crank pin carries a spur gear 9 which, when the long-hand crank pin 14 is moved downward against the action of the helical spring 6, can be brought into meshing contact with the crown wheel 4.
- an overrun cam 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 motor 1 to be interrupted.
- 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.
- the overrun cam 1o is arranged in the region of the long-hand crank pin so that it is mounted in the track running around the crown wheel 4 and can thus be accommodated in a space-saving manner, but is sufficient space for the trouble-free movement of the long-hand crank pin is available.
- the long-hand crank pin is denoted by 114
- the overrun cam bears the reference number 1 00
- the spur gear has the reference number 19
- the helical spring required in this embodiment also the reference number 16.
- the motor can be seen at 1 and the motor output shaft acts on a gear 27 which meshes with a gear 23 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.
- the embodiment according to FIG. 2 is much smaller and more space-saving and, in addition, 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 wave are switched off and the transmission ratio is improved.
Abstract
Description
Die Erfindung bezieht sich auf eine Notlanghandkurbel für motorische Antriebe von Toren, Rolladen, Deckengliedertoren od. dgl..The invention relates to an emergency long-hand crank for motor drives for gates, roller shutters, overhead sectional doors or the like.
Derartige Notlanghandkurbeln sind heute bekannt und stellen üblicherweise einen Kontakt mit der sogenannten Motornotachse dadurch her, daß zwischen dem Langhandkurbelzapfen und der Motornotachse eine Rutschkupplung oder Klauenkupplung angeordnet ist. Während die Rutschkupplung nicht die angestrebte und gewünschte Sicherheit erbringt, ist die Klauenkupplung eine zu aufwendige Konstruktion, so daß sie nicht in der erstrebenswerten kostengünstigen Weise und in großer Stückzahl herstellbar ist.Such emergency long-hand cranks are known today and usually make contact with the so-called engine emergency axis in that a slip clutch or claw clutch is arranged between the long-hand crank pin and the engine emergency axis. While the slip clutch does not provide the desired and desired safety, the claw clutch is a construction which is too complex, so that it cannot be produced in a desirable, inexpensive manner and in large numbers.
Der Erfindung liegt die Aufgabe zugrunde, eine Notlanghandkurbel zur eigentlichen Arbeitswelle zu schaffen, die kostengünstig herstellbar ist und außerdem nachträglich in einfachster Weise an bestehende Einrichtungen angebaut werden kann.The invention has for its object to provide an emergency long crank for the actual work shaft, which is inexpensive to manufacture and also retrospectively Lich can be easily added to existing facilities.
Diese der Erfindung zugrundeliegende Aufgabe wird gelöst durch ein mit der Arbeitswelle mittelbar oder unmittelbar verbundenes Kronenrad und eine federnde Lagerung eines Langhandkurbelzapfens, an dessen Endbereich ein Stirnrad angeordnet ist, das bei Bewegung des Langhandkurbelzapfens gegen die Wirkung der Feder einer Federlagerung mit dem Kronenrad in kämmenden Kontakt bringbar ist.This object on which the invention is based is achieved by a crown wheel connected directly or indirectly to the working shaft and a resilient mounting of a long-hand crank pin, at the end region of which a spur gear is arranged which, when the long-hand crank pin moves against the action of the spring of a spring bearing, in meshing contact with the crown wheel is feasible.
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.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.
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 Notkurbel verbessert, da das Kronenrad direkt auf die Schnekkenwelle 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 in that a direct action of the spur gear on the worm shaft vibrations within the gearbox binding can be switched off. In addition, the transmission ratio is improved in this arrangement for the emergency crank, since the crown gear acts directly on the worm shaft.
Das wesentliche Merkmal der Erfindung ist also darin zu sehen, daß bei Betätigen des Langhandkurbelzapfens durch das Zusammenwirken eines Kronenrades und eines Stirnrades eine Verbindung zur Arbeitswelle hin erfolgt, wobei der Langhandkurbelzapfen vorzugsweise in seiner Längsachse gegen die Kraft einer Feder bewegbar ist und dadurch diese beiden vorgenannten Getrieberäder miteinander in Kontakt bringbar sind.The essential feature of the invention is thus to be seen in the fact that when the long-hand crank pin is actuated, a connection to the working shaft takes place through the interaction of a crown gear and a spur gear, the long-hand crank pin preferably being movable in its longitudinal axis against the force of a spring and thereby these two aforementioned Gear wheels can be brought into contact with each other.
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.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Einrichtung sind in den Unteransprüchen definiert.Further advantageous refinements of the device according to the invention are defined in the subclaims.
Ausführungsbeispiele der Erfindung werden nachfolgend anhand 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.
- F ig. 1 shows a first embodiment of the invention, the emergency long-hand crank acting 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. 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
In diesem Gehäuse ist gegen die Kraft einer Wendelfeder 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 1 4 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 attached is closed. The helical spring 6 is arranged in a hood-shaped safety housing 7, which is fixed to the crank pin via a
Am oberen Ende trägt der Langhandkurbelzapfen ein Stirnrad 9, 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
Bevor dieser Kontakt stattfindet, läuft ein am Langhandkurbelzapfen 14 vorgesehener Auflaufnocken 1o 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, an
In besonders vorteilhafter Weise ist dabei vorgesehen, daß der Auflaufnocken 1o im Bereich des Langhandkurbelzapfens so angeordnet ist, daß er in der von 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 1o is arranged in the region of the long-hand crank pin so that it is mounted in the track running around the crown wheel 4 and can thus be accommodated in a space-saving manner, but is sufficient space for the trouble-free movement of the long-hand crank pin is available.
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 E, das Stirnrad 9 in einfachster Weise mit dem Kronenrad 4 in Kontakz bringeinfachster weise mit dem Kronenrad 4 in Kontakt bringbar ist, wobei gleichzeitig die Stromzufuhr zum Motor stillgesetzt ist und number über den Langhandkurbelzapfen und die daran anschließende Lanchandkurbel das Betätigen der Motornotachse 3 möglich ist.It can be seen that in the device according to the invention when the long-
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 23 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 denoted by 114, the overrun cam bears the reference number 1 00 , the spur gear has the
Im Gegensatz zu der in Fig. 1 dargestellten Ausführjngsform 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 is much smaller and more space-saving and, in addition, the
