Definitions

  • the invention relates to the locking of doors, in particular folding folding doors, on wagons for rail-bound passenger transport.
  • An additional locking of the door takes place via a locking bar that can be operated transversely to the direction of movement of the door.
  • the locking bar actuates a plunger in its closed end position, which in turn pivots a lever through which an electrical limit switch is actuated.
  • a circuit is interrupted by this electrical switch when actuated, so that a signal is only emitted due to the closed circuit when the switch is not actuated.
  • a direct actuation of the switch by the locking bar was avoided in order to prevent incorrect actuation. It should be borne in mind that the path to actuating an electrical switch is generally small, whereas relative movements between the switch and the locking bar can only be caused by vibrations, which lead to unwanted signals, so that disturbances to normal train traffic occur.
  • Such disturbances can be caused not only by vibrations, but also by different thermal expansion.
  • the electrical switch for signaling is usually on the car body Be provided so that the relative change in position of the switch is also caused by the action of heat and cold.
  • the locking bar is not exposed to the sun as much as the wagon body as such, so that at least thereby time-delayed thermal expansions occur, which means that the thermal expansion or contraction is another important disturbing factor, which can overlap, for example, with the vibrations.
  • the present invention is based on a prior art, as given by DE-A1 20 33 009 and has set itself the task of creating locks for doors on wagons for rail-bound traffic, which provide reliable feedback on the closed state of the Allow doors without having to provide an additional mechanical actuation mechanism that z. B. in the dirty state can lead to further malfunctions, which does not cause false messages even in the case of vibrations and thermal expansion and contraction.
  • the lock according to the invention for doors, in particular folding folding doors, on wagons for rail-bound passenger transport, the door articulated on the wagon body in the closed position being able to be fixed to the wagon body in at least one rest, in particular an upper rest, in at least one rest, in particular an upper rest, in the closed position via at least one rest is and an electric switch for the electrical display, in particular remote display, the closed position of the door can be actuated via the locking bar, consists essentially in that an electric proximity switch can be actuated via the locking bar, the sensor in the direction of movement to the closed position of the locking bar seen, in, especially after, the rest is arranged.
  • any mechanical actuation of the switch can be dispensed with, and safe signaling, ie avoidance of false signals, can already be guaranteed by the sensitivity of the sensor.
  • the sensor of the switch can be actuated by changing the inductance, interference factors such as those caused, for example, by electrostatic charges, such as those caused by synthetic fiber floor coverings, can be avoided in a particularly simple manner.
  • the locking bar can be magnetized in its end region, a particularly strong change in the inductance can be achieved, thus changing the sensitivity is not only possible through the sensor, but also through the locking bar itself.
  • the sensor or its response surface in the closed position of the locking catch surrounds this or at least overlaps it, a reliable function can be achieved even when the locking rod is displaced transversely to the direction of movement, which can be kept free from thermal expansion, shocks and other influences.
  • At least one locking bar can be actuated via a locking lever, the locking bar only actuating the proximity switch when the locking lever is in the closed end position, then an inevitable notification of the double locking is given.
  • the door has an associated, in particular visual, remote display for the open position of the doors, only attention is required when the doors are open, whereas with the doors closed there is no additional concentration for the driver of the train.
  • a, in particular optical, display is provided in and / or in the area of the door for the open position of this door, maintenance personnel can determine faults on site, regardless of the remote display, and can also remedy them at short notice.
  • the locking bar has a friction-reducing coating in its end region, tilting or tensioning of the locking bar in the catch and thus a false display can be avoided in a particularly simple manner.
  • the senor is arranged at least 0.5 times the thickness, in particular the diameter of the locking bar after the detent, then on the one hand the free movement of the locking bar due to thermal expansion and vibration is taken into account particularly favorably , furthermore a safe application of the sensor is guaranteed.
  • the locking bar is passed through a seal which is arranged on the front side of the door and in the closed position of this rests on the wagon body, in particular the latch for the locking bar, exposure to the sensors, for example with precipitation, can simply be avoided, furthermore contamination the end region of the locking bar is also particularly easily avoided.
  • the closing movement is usually actuated centrally, for example from the driver's cab of the locomotive or the railcar.
  • Such systems are well known and are described, for example, in DE-A1 20 33 009.
  • the locking bar 3 is passed through a seal 4, which consists of rubber-elastic material and abuts a sealing lip 5 on the car body.
  • the locking bar 3 in turn extends into the latch 6, so that a violent opening of the door can be safely prevented.
  • the lifting height of the locking bar is 10 mm, and it is in the upper position with its end face and the detent 6 by half the diameter D of the locking bar from the lower end of the sensor 7.
  • the large lifting height enables the door to be securely fixed, whereas, on the other hand, the distance from the sensor - in the drawing case at room temperature - can reliably prevent malfunctions in both the display and the fixing of the rotating folding door.
  • the sensor 7 is sensitive to changes in inductance, such as the approach of a steel locking bar. In order to increase the sensitivity, the end of the locking bar can either carry a magnet or be magnetized itself.
  • An electrical line 8 leads from the sensor 7 to the switch 9.
  • This switch 9 has several terminals which serve on the one hand for the power supply and on the other hand are connected to a signal lamp in the driver's cab and a signal lamp in the area of the rotating folding door.
  • Sensors can be provided both in the closing area of the upper and the lower locking bar, these Sensors can be connected in series, for example, so that the signal lamps light up when a locking bar is open.
  • the ends of the locking bars may also be desirable for the ends of the locking bars to have a coating 10 in order to reduce the frictional resistance in the catch 6.
  • capacitive sensors can also be used, for example, or a radiation barrier, e.g. B. light barrier, suitable for the purpose of the invention.
  • a radiation barrier e.g. B. light barrier
