Definitions

  • the invention relates to a device for actuating and unlocking the shaft doors of an elevator, which has a first coupling element arranged on the shaft door and a second coupling element arranged on the car door, which can be brought into engagement with the first coupling element in the area of one floor, one at the shaft door arranged locking member is provided, which is operatively connected to the second coupling member when the cabin is held on one floor such that the shaft door is unlocked and can be opened.
  • Such devices have the purpose of opening and closing horizontally displaceable cabin and shaft doors synchronously by means of a door drive mounted on the cabin when stopped on a floor.
  • the movable coupling member presses on a roller mounted on a lever, so that a rod attached to the other end of the lever is shifted upward.
  • the upper end of the rod is connected to a pawl that thereby being pivoted upwards, the shaft door being unlocked and a control circuit being opened.
  • an electromagnet is installed directly above a movable coupling member in the cabin door and is connected to the coupling member by a joint.
  • the movable coupling member is held in the uncoupled position due to the force of gravity, while when the electromagnet is excited, a fixed coupling member attached to the shaft door engages.
  • Another electromagnet arranged on the cabin is connected to a lever arrangement to which a cam is articulated.
  • the cam rests on a roller mounted on a lever, the lever being connected to a pawl and being rotatably arranged on the shaft door.
  • the further electromagnet drops off, so that the cam is moved down and pressed against the roller.
  • the lever and thus also the pawl perform a swiveling movement, so that the shaft door is unlocked and a control circuit is opened.
  • the invention has for its object to provide a device according to the preamble, in which noises and vibrations when engaging or disengaging the coupling members and unlocking or locking the shaft doors are avoided, no high demands on manufacturing and assembly accuracy have to be provided and fewer mechanical components are required.
  • the coupling members consist of magnets which are designed such that a north pole of the first coupling member faces a north pole of the second coupling member, and a south pole of the first coupling member opposite a south pole of the second coupling member, separated by an air gap in the direction of movement of the doors.
  • a further magnet is arranged on the locking member, which is located in the area of one floor in the direction of movement of the doors with one pole opposite a pole of the same name of the second coupling member with an air gap.
  • the advantages achieved by the invention are to be seen in particular in the fact that noises and vibrations are largely avoided because of the contactless interlocking of the coupling members and the contactless driving of the shaft door as well as the contactless actuation of the locking member.
  • the shaft door is gradually slowed down to a stop by the repelling forces of the poles of the same name.
  • the doors can be opened faster, thereby increasing the effective door hold-open time, since the low initial speed required for some conventional devices for coupling and unlocking is not necessary.
  • Further advantages can be seen in the fact that fewer mechanical components are required and, because of the air gaps between the magnetic poles, coarser manufacturing and assembly tolerances are permissible. If the vehicle stops on a floor and there is a power failure, the doors can be opened by hand, since mechanical contact can then be made between the coupling members and between the second coupling member and the locking member.
  • a first coupling member 3 is arranged on the shaft door and a second coupling member 4 on the cabin door 2.
  • the coupling members 3, 4 are magnets of the same pole strength, wherein in a preferred embodiment the first coupling member 3 is a U-shaped permanent magnet and the second coupling member 4 consists of two identical electromagnets 4.1, 4.2.
  • the coupling members 3, 4 are arranged such that the legs 3.1, 3.2 of the U-shaped permanent magnet, which form magnetic poles in the area of one floor, overlap with an air gap on their outer sides.
  • the one electromagnet 4.1 with its north pole N faces the north pole N
  • the other electromagnet 4.2 with its south pole S faces the south pole S of the u-shaped permanent magnet in the direction of movement of the doors.
  • a u-shaped electromagnet can be used instead of the u-shaped permanent magnet, one leg 3.1 forming a north pole and the other leg 3.2 forming a south pole.
  • the electromagnets 4.1, 4.2 in principle consist, as is known, of hollow coils with cores made of ferromagnetic material, the electromagnets also being known, as is also known Reversing the connections of a supplying DC voltage source 5 can be reversed.
  • the locking member 6 has a pawl 7 rotatably mounted on the shaft door 1 and a toggle lever 8.
  • the toggle lever 8 consists of a first and second lever 9, 10, which are articulated at one end. The other end of the first lever 9 is rotatably attached to the pawl 7, while the other end of the second lever 10 is rotatably mounted on the shaft door 1.
  • a rod-shaped permanent magnet 12 is attached to the knee lever 8, one pole of which, in the presence of the cabin on one floor, is opposite a pole of the same name of the second coupling member 4 in the direction of movement of the doors with an air gap.
  • the electromagnetic second coupling part 4 When stopping on a floor, the electromagnetic second coupling part 4 is activated first, whereby the repulsive forces of the poles of the same name, for example two north poles, the rod-shaped permanent magnet 12 and the electromagnet 4.1 push the toggle lever 8 without contact in the direction of the arrow and the pawl 7 is pivoted upwards is so that the shaft door 1 is unlocked (Fig. 4). Thereafter, a door drive (not shown) arranged on the cabin is started and the shaft door 1 is carried along by the cabin door 2 without contact by the repulsive forces acting between the first and second coupling parts 3, 4. This will decrease in the direction of movement of the doors, for example indicated by the arrow (Fig.
