Definitions

  • the invention relates to a device for unlocking a landing door, an elevator installation with such a device and a method for unlocking such a landing door.
  • An elevator installation usually comprises an elevator car which can be moved within an elevator shaft.
  • components of the elevator installation for example the lower area of the elevator cage or components arranged in the shaft pit of the elevator shaft, to maintenance, a service technician enters the shaft pit through a lowermost shaft door.
  • the service technician unlocks the bottom landing door to open this shaft door and thus leave the elevator shaft.
  • the corresponding locking device of the shaft door is located in the upper door area of this shaft door. It is known that, for unlocking from the interior of the elevator shaft, an unlocking cable can be fixed to the latch of the locking device, this unlocking cable extending from the locking device into the lower door region of the elevator door. The service technician can pull this release cable to unlock the elevator door.
  • each elevator door has a force storage device for the automatic closure of the elevator door in the event of a power failure.
  • a disadvantage of such an embodiment of the elevator door is that the presence of the energy storage device and the unlocking device is a component-rich, so complicated, construction of the device.
  • a device for unlocking an elevator door which has a simplified structure. This object is achieved by a device for unlocking a shaft door, the device comprising:
  • a door leaf which is displaceable between an open position and a closed position
  • a latch arranged on the door leaf for locking the door leaf in its closed position
  • a force accumulator which is coupled to the door leaf and which provides energy for the movement of the door leaf into its closed position upon failure of the energy supply necessary for driving the door leaf
  • the energy storage device is coupled by means of an elastic element with the door leaf, that by displacing the energy storage device in the arranged in its closed position door leaf, the bolt is displaceable in its unlocked position.
  • an elevator installation which comprises a plurality of shaft doors arranged one above the other, through which shaft doors of the elevator shaft of the elevator installation can be walked by a plurality of floors arranged one above the other, the device being arranged on a lowermost one of the shaft doors.
  • the object is also achieved by a method for unlocking an elevator door with such a device, wherein the door leaf is unlocked by displacing the force accumulator.
  • the invention is based on the finding that a force storage device is usually arranged in the lower region of the elevator door and thus easily accessible for a service technician located in the shaft pit when this elevator door is arranged directly on the shaft pit.
  • this energy accumulator is coupled to an upper region of the elevator door or of the door leaf, in which upper region the latch for locking the elevator door is also connected. is ordered.
  • the elastic element With the aid of the elastic element, it is consequently possible in the closed position of the door leaf to generate a movement on the latch in the upper region of the door leaf in the case of a preferably manual displacement of the force accumulator.
  • This movement performed in the lower door area is used to transfer the latch from its locked position to its unlocked position by means of the elastic element in the upper door area and thus to release the door leaf to the opening.
  • Elastic elements in the sense of this description also include devices which undergo a change in length by displacing the force accumulator for the purpose of unlocking, this change in length being reversed when the force accumulator resumes its starting position corresponding to the locked position of the latch.
  • the energy accumulator is coupled to the door leaf by means of an attachment point arranged on the door leaf. In this way it can be ensured that the movement of the energy accumulator causes the door leaf to be closed when the door leaf is open.
  • the elastic element is supported at the fastening point and can be relieved by the displacement of the force accumulator displacing the latch into its locking position. It is thus possible to achieve that the movement of the energy store in the lower region of the elevator door causes a movement in the upper region of the elevator door, wherein the movement in the upper region of the elevator door is used for unlocking the door leaf.
  • the elastic element may be fixed for this purpose at the attachment point or merely supported on this.
  • the elastic element may be supported at the attachment point and be extensible by the relocation of the force accumulator displacing the latch into its locked position.
  • the extended arm of the bolt By means of a fixed to the rope actuator can therefore the extended arm of the bolt are pivoted so that the bolt assumes its unlocked position.
  • the elastic element is formed by a spring element such that the spring element displaces the bolt into its unlocked position by displacing the force accumulator.
  • the force accumulator causes the elastic member formed by the spring member to be in a state that the extended arm of the latch is not operated when the force accumulator is not moved by a service technician.
  • the spring element is relieved or loaded and thus moves the bolt in its unlocked position.
  • a refinement of the device comprises a cable, which cable is connected at its first end to the energy store and at its second end to the elastic element arranged at the attachment point. In this way, a connection is created between the energy store, which can be moved by the service technician, and the bolt.
  • a closing weight or by a closing spring are usually in the lower region of the door jamb of the corresponding door can be arranged and easily by a service technician reach or movable.
  • the door leaf is unlocked by pulling in the direction of a shaft pit pulling the force accumulator or by lifting the force accumulator.
  • a constellation which causes a unlocking of the shaft door by a downward pulling the energy accumulator, it is advantageous that the shaft door is not unlocked by an optionally torn rope.
