Description

Die Erfindung betrifft eine Hilfseinrichtung zum Verschieben einer Nutzlastaufnahme eines Aufzugs.The invention relates to an auxiliary device for moving a payload of a lift.

Üblicherweise werden Aufzüge mit einer derartigen Hilfseinrichtung zum Transport von Personen oder Waren in vertikaler Richtung zwischen mindestens zwei vertikal versetzten Stationen benutzt und sind in einem Aufzugsschacht in oder an einem Gebäude angeordnet. Die den Aufzugsschacht begrenzende Wandung weist in der Höhe jeder Station eine mittels einer Türvorrichtung verschliessbare Lade/EntladeÖffnung beziehungsweise Türöffnung auf, an welche eine Wartezone angrenzt, in der sich die Nutzlasten und/oder Passagiere vor dem Beladen beziehungsweise nach dem Entladen der Nutzlastaufnahme befinden. Ein solcher Aufzug umfasst im Wesentlichen die erwähnte Nutzlastaufnahme, beispielsweise eine Plattform oder eine Kabine, ein Gegengewicht zur Nutzlastaufnahme, eine Antriebseinrichtung, eine Bremseinrichtung, mindestens ein flexibles Trag- und Antriebselement, das heisst ein Kabel oder Seil, welches über eine Treibscheibe der Antriebsvorrichtung läuft und auf der einen Seite der Treibscheibe mit der Nutzlastaufnahme und auf der anderen Seite der Treibscheibe mit dem Gegengewicht verbunden ist. Im weiteren besitzt der Aufzug die erforderliche Leistungs- und Steuerungselektronik. Die Antriebseinrichtung befindet sich im obersten Bereich des Aufzugsschachtes oberhalb der durch die Nutzlastaufnahme nutzbaren Zone desselben. Erfolgt eine Bremsung infolge eines technischen Problems beziehungsweise eine Notbremsung, so befindet sich die Lastaufnahme im allgemeinen nicht in einer der Stationen. Die Hilfseinrichtung ist für solche Fälle vorgesehen und dient dazu, in kurzer Zeit die Nutzlastaufnahme zu einer der Stationen zu bringen, damit die transportierten Personen und/oder Waren nicht in beziehungsweise auf der Nutzlastaufnahme im Aufzugsschacht verharren müssen. Die Hilfseinrichtung umfasst einerseits eine temporär aktivierbare Bremsfreigabevorrichtung, durch welche die Bremse gelöst wird und anderseits eine bei aktivierter Bremsfreigabevorrichtung betätigbare Hilfsantriebsvorrichtung, um die Nutzlastaufnahme zu heben oder zu senken und um sie in eine der Stationen oder mindestens in einen Bereich in Stationsnähe gebracht werden, wo eine gefahrlose Entladung stattfinden kann. Für Aufzüge, welche in Gebäuden mit wenigen Stockwerken montiert werden und zum Transport verhältnismässig geringer Nutzlasten ausgelegt sind, werden vorzugsweise einfache, manuell betätigbare mechanisch wirkende Bremsfreigabe- und Hilfsantriebsvorrichtungen vorgesehen.Typically, elevators are used with such an auxiliary device for transporting people or goods in the vertical direction between at least two vertically offset stations and are arranged in an elevator shaft in or on a building. The wall delimiting the elevator shaft has, at the level of each station, a loading / unloading opening or door opening which can be closed by means of a door device, to which a waiting zone adjoins, in which the payloads and / or passengers are located before loading or after unloading the payload receptacle. Such an elevator essentially comprises the aforementioned payload receptacle, for example a platform or a cabin, a counterweight for the payload receptacle, a drive device, a braking device, at least one flexible support and drive element, ie a cable or rope which runs over a traction sheave of the drive device and on one side of the traction sheave with the payload and on the other side of the traction sheave is connected to the counterweight. Furthermore, the elevator has the required power and control electronics. The drive device is located in the uppermost region of the elevator shaft above the through the Nutzlastaufnahme usable zone of the same. If braking occurs as a result of a technical problem or emergency braking, the load bearing is generally not located in one of the stations. The auxiliary device is provided for such cases and serves to bring the payload recording to one of the stations in a short time so that the transported persons and / or goods do not have to remain in or on the payload in the elevator shaft. The auxiliary device comprises on the one hand a temporarily activatable brake release device, by which the brake is released and on the other hand actuatable with activated brake release device auxiliary drive device to lift the payload recording or lower and brought to them in one of the stations or at least in an area near the station, where a safe discharge can take place. For elevators, which are mounted in buildings with a few floors and are designed to transport relatively low payloads, preferably simple, manually operable mechanically acting brake release and auxiliary drive devices are provided.

Die EP 0 947 460 A1 beschreibt eine solche Hilfseinrichtung für einen Personenaufzug, mit einer Bremsfreigabevorrichtung und einer Hilfsantriebsvorrichtung. Die Bremsfreigabevorrichtung und die Hilfsantriebsvorrichtung werden durch ein polyvalentes Kurbelgestänge betätigt. Das obere Ende des Kurbelgestänges ist sein Wirkende. Es ist mit der Bremsfreigabevorrichtung und der Hilfsantriebsvorrichtung gekoppelt oder koppelbar und befindet sich im obersten Teil des Aufzugsschachtes. Das untere Ende des Kurbelgestänges ist sein Betätigungsende und ist mit den erforderlichen Betätigungsgriffelementen versehen. Das Kurbelgestänge ist schwenkbar ausgebildet und gelagert, derart, dass es sich aus einer Ruhestellung, in welcher es sich vollständig im Aufzugsschacht befindet, in eine Arbeitsstellung schwenken lässt, in welcher sein Betätigungsende durch eine Öffnung einer den Aufzugsschacht begrenzenden Wandung ragt oder von einer solchen Öffnung aus betätigbar ist. Diese Öffnung befindet sich im Bereich des Warteraums der obersten Station des Aufzugs, so dass das Kurbelgestänge an seinem Betätigungs-Ende über die Betätigungsgriffelemente von einer im Warteraum dieser Station stehenden Person leicht betätigt werden kann. Der offensichtliche Nachteil dieser sonst sehr geeigneten Einrichtung ist darin zu sehen, dass ihre Betätigung unmittelbar unterhalb des Antriebsbereichs des Aufzugsschachtes erfolgen muss, wozu die Öffnung im allgemeinen in der er Höhe der obersten Station beziehungsweise des obersten vom Aufzug bedienten Geschosses angeordnet wird. Dieser Nachteil fällt besonders dann ins Gewicht, wenn sich diese Station innerhalb einer Wohneinheit befindet, wie es häufig in anspruchsvollen Wohnungen und insbesondere in Maisonette-Wohnungen und Penthouse-Wohnungen der Fall ist.The EP 0 947 460 A1 describes such an auxiliary device for a passenger elevator, with a brake release device and an auxiliary drive device. The brake release device and the auxiliary drive device are actuated by a polyvalent crank linkage. The upper end of the crank rod is its effect end. It is coupled or coupleable to the brake release device and the auxiliary drive device and is located in the uppermost part of the elevator shaft. The lower end of the crank linkage is its operating end and is with the required Provided actuating handle elements. The crank linkage is designed to be pivotable and mounted such that it can be pivoted from a rest position in which it is completely located in the elevator shaft into a working position in which its actuating end projects through an opening of a wall delimiting the elevator shaft or from such an opening off is actuated. This opening is located in the area of the waiting room of the uppermost station of the elevator, so that the crank rod can be easily actuated at its actuating end via the actuating handle elements from a person standing in the waiting room of this station. The obvious disadvantage of this otherwise very suitable device is the fact that its operation must be carried out immediately below the drive range of the elevator shaft, for which purpose the opening is generally arranged in the height of the uppermost station or of the uppermost elevator-operated projectile. This disadvantage is particularly significant when this station is located within a residential unit, as is often the case in sophisticated apartments and especially in duplex apartments and penthouse apartments.

Mit der DE GM 296 15 921 U1 ist eine diesbezüglich verbesserte Hilfseinrichtung bekannt geworden, bei welcher die Bedienung der Einrichtung von einem Standort aus erfolgen kann, der in einem gewissen Abstand von der obersten Station des Aufzuges liegt. Allerdings ist diese Hilfseinrichtung verhältnismässig kompliziert aufgebaut.With the DE GM 296 15 921 U1 an improved auxiliary device is known, in which the operation of the device can be carried out from a location which is located at a certain distance from the uppermost station of the elevator. However, this auxiliary device is constructed relatively complicated.

Es ist daher eine Aufgabe der Erfindung, eine Hilfseinrichtung der eingangs genannten Art vorzuschlagen, die bezüglich Aufbau, Anordnung und Betrieb einfach ist und die von einem Standort aus bedient werden kann, der eines oder mehrere Geschosse unterhalb der obersten vom Aufzug bedienten Station liegt.It is therefore an object of the invention to propose an auxiliary device of the type mentioned, which is simple in construction, layout and operation, and which can be operated from a location one or more floors below the uppermost station served by the elevator.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäss durch die Merkmale des Patentanspruchs 1.The solution of this object is achieved according to the invention by the features of claim 1.

Bevorzugte Weiterbildungen der erfindungsgemässen Hilfseinrichtung sind durch die vom Anspruch 1 abhängigen Ansprüche 2 bis 6 definiert.Preferred developments of the auxiliary device according to the invention are defined by claims 2 to 6 dependent on claim 1.

Die Hilfseinrichtung nach der Erfindung weist zur Aktivierung der Bremsfreigabevorrichtung und zur Betätigung der Hilfsantriebsvorrichtung ein herkömmliches Kurbelgestänge auf, dessen wirksame Länge in vertikaler Richtung aber durch eine Gestängeverlängerung vergrössert ist, welche zwischen Bremsfreigabevorrichtung und Hilfsantriebsvorrichtung einerseits und herkömmlichem Kurbelgestänge anderseits angeordnet ist. Es werden also nicht die Längselemente des herkömmlichen Kurbelgestänges länger ausgebildet, sondern es wird im Wesentlichen ein Kurbelgestänge in einer üblichen Länge, das eine Höhendifferenz von höchstens einem Geschoss überbrückt, verwendet. An das obere Ende dieses Kurbelgestänges schliesst sich die Gestängeverlängerung an. Das Wirkende des Kurbelgestänges ist mit dem unteren Ende der Gestängeverlängerung gekoppelt, und das Betätigungsende des Kurbelgestänges ist aus einer Ruhestellung innerhalb des Aufzugsschachtes in eine Arbeitsstellung bringbar, in welcher es von einer ausserhalb des Aufzugsschachtes befindlichen, die Hilfseinrichtung bedienenden Person betätigbar ist.The auxiliary device according to the invention comprises a conventional crank linkage for activating the brake release device and for actuating the auxiliary drive device, the effective length of which is increased in the vertical direction by a linkage extension which is arranged between brake release device and auxiliary drive device on the one hand and conventional crank linkage on the other hand. Thus, the longitudinal elements of the conventional crank linkage are not made longer, but essentially a crank rod of a standard length, which bridges a height difference of at most one projectile, is used. At the upper end of this crank linkage joins the boom extension. The operative end of the crank linkage is coupled to the lower end of the linkage extension, and the actuating end of the crank linkage can be brought from a rest position within the elevator shaft into a working position in which it can be actuated by a person operating outside of the elevator shaft and operating the auxiliary device.

Hierzu ist eine Öffnung in der Wandung des Aufzugsschachtes vorgesehen.For this purpose, an opening in the wall of the elevator shaft is provided.

Die wirksame Länge der Gestängeverlängerung wird in Abhängigkeit des Vertikalabstandes zwischen dem Wirkende des Kurbelgestänges und der Bremsfreigabe- und Hilfsantriebsvorrichtung gewählt.The effective length of the linkage extension is selected as a function of the vertical distance between the action end of the crank linkage and the brake release and auxiliary drive device.

Es hat sich als günstig erwiesen, die Gestängeverlängerung so auszubilden, dass sie sich aus mehreren in Serie angeordneten Verlängerungsgliedern zusammensetzt.It has proven to be beneficial to form the rod extension so that it is composed of several series-arranged extension members.

Besonders vorteilhaft ist es, eines oder gegebenenfalls auch mehrere Verlängerungsglieder elastisch, das heisst als flexible Welle, auszubilden. Beispielsweise erlaubt es ein direkt mit der Bremsfreigabevorrichtung und der Hilfsantriebsvorrichtung gekoppeltes elastisches Verlängerungsglied, das nach unten folgende Verlängerungsglied an einer besonders günstigen Stelle anzuordnen. Auch das unterste Verlängerungsglied kann elastisch ausgebildet sein, um das daran anschliessende Kurbelgestänge an einer geeigneten Stelle anzuordnen.It is particularly advantageous to form one or possibly also a plurality of extension members elastically, that is to say as a flexible shaft. For example, an elastic extension member directly coupled to the brake release device and the auxiliary drive device allows the extension member to be positioned downward at a particularly favorable location. Also, the lowermost extension member may be formed elastically to arrange the adjoining crank linkage at a suitable location.

Im allgemeinen wird dasjenige Verlängerungsglied, das in der Vertikalrichtung die grösste wirksame Länge aufweist, starr ausgebildet und ortsfest im Aufzugsschacht montiert.In general, that extension member which has the greatest effective length in the vertical direction, rigid and mounted stationary in the elevator shaft.

Mit dem untersten Verlängerungsglied der Gestängeverlängerung wird dann das Wirkende des eigentlichen Kurbelgestänges gekoppelt. Die Koppelung erfolgt an einer Koppelungsstelle um welche das Kurbelgestänge aus seiner Ruhelage so verschwenkbar ist.The action end of the actual crank linkage is then coupled with the lowermost extension link of the linkage extension. The coupling takes place at a coupling point around which the crank rod from its rest position is so pivotable.

Mit in geeigneten Abständen angebrachten Markierungen am flexiblen Trag- und Antriebsorgan kann mit einem Blick durch die Öffnung erfasst werden, wann die Nutzlastaufnahme die genaue Höhenlage einer Station erreicht hat.With appropriately spaced marks on the flexible support and drive member can be detected with a view through the opening when the payload recording has reached the exact altitude of a station.

Vorzugsweise umfasst die Hilfseinrichtung auch eine Bildübertragungsvorrichtung, mit einem Sensor zum Erfassen von Bildern des obersten Bereiches des Aufzugsschachtes, mit einer Anzeigevorrichtung zum Visualisieren dieser Bilder im Bereich der Öffnung und mit einer Transferstrecke zum Verbinden des Sensors mit der Anzeigevorrichtung zwecks Übermittlung der Bilder.The auxiliary device preferably also comprises an image transmission device with a sensor for capturing images of the uppermost region of the elevator shaft, with a display device for visualizing these images in the region of the opening and with a transfer path for connecting the sensor to the display device for the purpose of transmitting the images.

Damit gegebenenfalls ein Benutzer des Aufzugs, der sich in einem ausserhalb einer Station stehenden Aufzug befindet, selbst die Bremsfreigabevorrichtung und die Hilfsantriebsvorrichtung betätigen und sich dadurch selbst befreien kann, wird mittels einer Flexwelle zusätzlich eine Verbindung zwischen der Bremsfreigabevorrichtung und Hilfsantriebsvorrichtung einerseits und einem HilfsKurbelgestänge anderseits, das von der blockierten Nutzlastaufnahme beziehungsweise Kabine aus bedienbar ist, vorgesehen. Das von der Nutzlastaufnahme aus zu betätigende Ende des Hilfs-Kurbelgestänges kann hinter einer Türe oder Klappe angeordnet sein, deren Schliessmechanismus vorzugsweise zur Vermeidung von Missbräuchen des Hilfs-Kurbelgestänges mit einer Plombe versehen wird. Im Weiteren kann die oben erwähnte Bildübertragungsvorrichtung eine Hilfsanzeigevorrichtung aufweisen, die von der Nutzlastaufnahme aus einsehbar ist.In order for a user of the elevator, who is located in an out-of-station elevator, to actuate the brake release device and the auxiliary drive device himself and thus free himself, a connection between the brake release device and auxiliary drive device on the one hand and an auxiliary crank linkage on the other hand is additionally provided by means of a flexible shaft. which is operable from the blocked payload or cab, provided. The end of the auxiliary crank linkage to be actuated from the payload receptacle can be arranged behind a door or flap, the closing mechanism of which is preferably provided with a seal to prevent misuse of the auxiliary crank linkage. Furthermore, the above-mentioned image transmission device may have an auxiliary display device which can be viewed from the payload receptacle.

Die Bremsfreigabevorrichtung 26 und die Hilfsantriebsvorrichtung 28 sind Bestandteile einer Hilfseinrichtung 30, welche dazu dient, die Nutzlastaufnahme 14 zu verschieben, wenn sie infolge technischer Probleme durch die Bremseinrichtung 24 zwischen zweien der Stationen 12.1 bis 12.4 blockiert ist. Zur Verschiebung der blockierten Nutzlastaufnahme 14 in eine Station wird von einer bedienenden Person 1 im Warteraum der Station 12.1 die Bremsfreigabevorrichtung 26 aktiviert und während der Aktivierung der Bremsfreigabevorrichtung 26 die Hilfsantriebsvorrichtung 28 betätigt. Unter der Wirkung der Hilfsantriebsvorrichtung 28 dreht sich die Treibscheibe 18, wodurch das flexible Trag- und Antriebselement 16 in Bewegung gesetzt wird, mit der Folge, dass die Nutzlastaufnahme 14 je nach der Drehrichtung der Treibscheibe 18 angehoben oder, wie es im allgemeinen der Fall ist, abgesenkt wird. Die bedienende Person 1 kann sich hierbei im Warteraum einer der Stationen 12.1 bis 12.3, jedenfalls aber unterhalb der obersten Station 12.4, welche durch den Aufzug 10 bedient wird, befinden. Im dargestellten Ausführungsbeispiel ist die Nutzlastaufnahme 14, wie schon erwähnt, zwischen den Stationen 12.1 und 12.2 blockiert und soll mittels der Hilfsantriebsvorrichtung in die Station 12.1 gebracht werden, wo ihre Lage mit 14' angedeutet ist.The in FIG. 1 illustrated elevator 10 is arranged in an elevator shaft 11 and operates several stations 12.1, 12.2, 12.3, 12.4 in superimposed floors. In each of the floors, the elevator shaft 11 has a door opening, which is closed by means of a door, not shown. The door of a station can only be opened when a Nutzlastaufnahme 14 of the elevator 10 is resting in this station. On each floor are waiting rooms in front of the doors, whose walk-in floor areas are marked 13.1, 13.2, 13.3, 13.4. The vertical distance Δh of two adjacent floors is the distance between the accessible floor areas of two adjacent floors. Blocked in the elevator shaft 11 between the stations 12.1 and 12.2 is the above-mentioned payload receptacle 14, which is designed here as a cabin. The payload receptacle 14 is attached to one end of a flexible support and drive element 16. Starting from the payload recording 16 runs the flexible support and Drive element 16 up to a traction sheave 18 in the uppermost region of the elevator shaft 11, around this traction sheave 18 and back down to a counterweight 20 of the payload receptacle 14. To drive the traction sheave 18 is a drive device 22. In the upper region of the elevator shaft 11 is also a braking device 24. Furthermore, in the uppermost area of the elevator shaft 11, a temporarily activatable brake release device 26 and an auxiliary drive device 28 for the traction sheave 18. The brake release device 26 and the auxiliary drive device 28 are components of an auxiliary device 30, which serves to move the payload receptacle 14, if it is blocked due to technical problems by the braking device 24 between two of the stations 12.1 to 12.4. To move the blocked payload receptacle 14 into a station, the brake release device 26 is activated by a serving person 1 in the waiting room of the station 12 and the auxiliary drive device 28 is actuated during the activation of the brake release device 26. Under the action of the auxiliary drive device 28, the traction sheave 18 rotates, causing the flexible support and drive element 16 to move, with the result that the payload receptacle 14 is raised depending on the direction of rotation of the traction sheave 18 or, as is generally the case , is lowered. The serving person 1 can be located in the waiting room of one of the stations 12.1 to 12.3, but in any case below the top station 12.4, which is operated by the elevator 10. In the illustrated embodiment, the payload receptacle 14, as already mentioned, is blocked between the stations 12.1 and 12.2 and is intended by means of Auxiliary drive device are brought into the station 12.1, where its position is indicated by 14 '.

Zur Betätigung der Bremsfreigabevorrichtung 26 und der Hilfsantriebsvorrichtung 28 dient ein Kurbelgestänge 40, welches oben durch eine Gestängeverlängerung 43 verlängert ist, die ihrerseits ein unteres Verlängerungsglied 42 und ein oberes Verlängerungsglied 44 aufweist. Das Kurbelgestänge 40 ist in seiner Ruhestellung vollständig im Aufzugsschacht 11 aufgenommen, während es in seiner Arbeitsstellung gemäss Figur 1 so verschwenkt ist, dass mindestens sein unteres Ende 40.1, das auch als Betätigungs-Ende 40.1 bezeichnet wird, durch eine Fensteröffnung 11.1 der Wandung des Aufzugsschachts 11 aus dem letzteren ragt. Das obere Ende 40.2 des Kupplungsgestänges 40, das auch als Wirk-Ende 40.2 bezeichnet wird, ist mit dem unteren Ende 42.1 des unteren Verlängerungsgliedes 42 gekoppelt. Dieses untere Verlängerungsglied 42 ist starr ausgebildet und ortsfest im Aufzugsschacht 11 montiert. Das obere Ende 42.2 des unteren, starren Verlängerungsgliedes 42 ist mit dem unteren Ende 44.1 des oberen Verlängerungsgliedes 44 gekoppelt. Das obere Verlängerungsglied 44 ist flexibel beziehungsweise in der Art einer Flexwelle ausgebildet. Das obere Ende 44.2 dieses flexiblen, oberen Verlängerungsgliedes 44 der Gestängeverlängerung 43 ist schliesslich mit der Bremsfreigabevorrichtung 26 und der Hilfsantriebsvorrichtung 28 gekoppelt.To actuate the brake release device 26 and the auxiliary drive device 28 is a crank link 40, which is extended above by a rod extension 43, which in turn has a lower extension member 42 and an upper extension member 44. The crank rod 40 is completely absorbed in its rest position in the elevator shaft 11, while in its working position according to FIG. 1 is pivoted so that at least its lower end 40.1, which is also referred to as actuation end 40.1, projects through a window opening 11.1 of the wall of the elevator shaft 11 from the latter. The upper end 40.2 of the coupling linkage 40, which is also referred to as the active end 40.2, is coupled to the lower end 42.1 of the lower extension member 42. This lower extension member 42 is rigid and mounted stationary in the elevator shaft 11. The upper end 42.2 of the lower, rigid extension member 42 is coupled to the lower end 44.1 of the upper extension member 44. The upper extension member 44 is flexible or formed in the manner of a flex shaft. The upper end 44.2 of this flexible upper extension member 44 of the linkage extension 43 is finally coupled to the brake release device 26 and the auxiliary drive device 28.

Die Gestängeverlängerung 43 erlaubt es, wie beabsichtigt, das Betätigungsende 40.1 des Kurbelgestänges 40 eines oder mehrere Geschosse unterhalb des obersten vom Aufzug bedienten Geschosses und anzuordnen. Im vorliegenden Ausführungsbeispiel bedient der Aufzug 10 die vier Stationen 12.1 bis 12.4, wobei 12.4 die oberste Station ist und die Bedienung der Hilfseinrichtung beziehungsweise die Betätigung des Kurbelgestänges 40 vom Warteraum der Station 12.1 aus vorgesehen ist. Die Hilfseinrichtung 30 kann daher, wie beabsichtigt, von einem Standort ausserhalb eines Penthouses mit internem Aufzugszugang betätigt werden. Es besteht die Möglichkeit, die Gestängeverlängerung 43 so auszubilden, dass die Hilfseinrichtung 30 sogar in grösserer Distanz, das heisst im Extremalfall vom Kellergeschoss aus, betätigt werden kann, wie es in Figur 1 dargestellt ist.The linkage extension 43 allows, as intended, the operating end 40.1 of the crank linkage 40 to dispose one or more projectiles below the uppermost elevator-supported projectile. In the present Embodiment operates the elevator 10, the four stations 12.1 to 12.4, wherein 12.4 is the top station and the operation of the auxiliary device or the operation of the crank link 40 from the waiting room of the station 12.1 is provided. The auxiliary device 30 can therefore, as intended, be operated from a location outside a penthouse with internal elevator access. It is possible to form the rod extension 43 in such a way that the auxiliary device 30 can be actuated even at a greater distance, that is to say in the extreme case from the basement, as is shown in FIG FIG. 1 is shown.

Die genaue Position der Nutzlastaufnahme kann durch entsprechende Markierungen des flexiblen Trag- und Antriebselementes 16 sichtbar gemacht werden.The exact position of the payload can be made visible by appropriate markings of the flexible support and drive element 16.

Insbesondere wenn die Hilfseinrichtung 30 in grosser Vertikaldistanz von der Antriebsvorrichtung betätigt wird, ist es vorteilhaft, die bisher beschriebenen Bestandteile der Hilfseinrichtung 30 durch eine Bildübertragungsvorrichtung zu ergänzen, um der bedienenden Person 1 die Möglichkeit zu geben, die Bewegung der Treibscheibe 18 oder sogar die Treibscheibe 18 selbst zu beobachten, und zwar auch dann, wenn kein Sichtkontakt besteht. Zu diesem Zwecke wird im Bereich der Treibscheibe 18 ein Sensor 52 zur Erfassung von Bildern insbesondere der Treibscheibe angeordnet, und im Bereich des Warteraumes der Station 12.1 wird eine Anzeigevorrichtung 54 zum Visualisieren dieser Bilder angeordnet. Der Sensor 52 und die Anzeigevorrichtung 54 sind durch eine geeignete Transferstrecke 56 zur Übertragung der von Sensor 52 erfassten Bilder verbunden, welche auf der Anzeigevorrichtung 54 visualisiert werden. Da für diese Bildübertragungsvorrichtung im allgemeinen Energie benötigt wird, die Blockierung der Nutzlastaufnahme 14 aber häufig auf einem Ausfall der Energiezufuhr beruht, ist ein Notstromaggregat 57 für die Bildübertragungsvorrichtung vorgesehen.In particular, when the auxiliary device 30 is operated at a large vertical distance from the drive device, it is advantageous to supplement the previously described components of the auxiliary device 30 by an image transfer device to give the operator 1 the opportunity to move the traction sheave 18 or even the traction sheave 18 even when there is no visual contact. For this purpose, a sensor 52 for capturing images, in particular of the traction sheave, is arranged in the region of the traction sheave 18, and a display device 54 for visualizing these images is arranged in the area of the waiting room of the station 12.1. The sensor 52 and the display device 54 are connected by a suitable transfer path 56 for transmitting the images captured by the sensor 52, which are visualized on the display device 54. Because for this Image transmission device is generally required energy, the blocking of the payload receptacle 14 but often based on a loss of power supply, an emergency generator 57 is provided for the image transfer device.

Figur 2 zeigt einen Aufzug 10 mit einer Hilfseinrichtung 30 nach der Erfindung, der im Wesentlichen gleich ausgebildet und mit gleichen Bezugszeichen versehen ist wie der Aufzug gemäss Fig. 1, der aber zusätzlich ein Hilfskurbelgestänge 140 aufweist, dessen Betätigungsende 140.1 im Bedarfsfall von der Nutzlastaufnahme 14 aus zugänglich bzw. betätigbar ist. Dieses Hilfskurbelgestänge 140 ist über eine flexible Gestängeverlängerung 144 mit der Bremsfreigabevorrichtung 26 und der Hilfsantriebsvorrichtung 28 unmittelbar oder mittelbar gekoppelt. FIG. 2 shows an elevator 10 with an auxiliary device 30 according to the invention, which is formed substantially the same and provided with the same reference numerals as the elevator according to Fig. 1 However, which additionally has an auxiliary crank linkage 140, the actuating end 140.1 is accessible or actuated if necessary by the payload receptacle 14 from. This auxiliary crank linkage 140 is coupled via a flexible link extension 144 with the brake release device 26 and the auxiliary drive device 28 directly or indirectly.

Die Erfindung ist für maschinenraumlose Aufzüge geeignet. Darunter sind Aufüge zu verstehen, die keinen eigenen Maschinenraum aufweisen. Deren Antrieb befindet sich somit neben dem Gegengewicht und der Auf zugkabine im Aufzugschacht.The invention is suitable for machine roomless elevators. These are lifts that do not have their own machine room. Their drive is thus next to the counterweight and on the elevator cab in the elevator shaft.
