Definitions

  • the invention relates to an auxiliary device for moving a payload of a lift.
  • 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.
  • 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 Nutzlasting 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.
  • brake release and auxiliary drive devices are provided for elevators.
  • 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.
  • the auxiliary device 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.

  • crank linkage 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.
  • an opening in the wall of the elevator shaft is provided.
  • 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.
  • rod extension so that it is composed of several series-arranged extension members.
  • extension members elastically, that is to say as a flexible shaft.
  • 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.
  • the lowermost extension member may be formed elastically to arrange the adjoining crank linkage at a suitable location.
  • extension member which has the greatest effective length in the vertical direction, rigid and mounted stationary in the elevator shaft.
  • crank linkage extension 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.
  • 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.
  • 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.
