Definitions

  • the invention relates to one in an elevator car arranged safety device to protect the Passengers from injuries caused by excessive Delays in the elevator car.
  • the known device is effective Safety device unusable because it is one of the Passenger impossible to recognize the lightning fast Dangerous situation and artistic practice in grasping the Rod requires. Others arranged inside the cabin Protective devices have so far not become known.
  • the invention seeks to remedy this.
  • the invention as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and to create a security device that provides security of the passengers effectively and without their assistance guaranteed.
  • Another advantage achieved by the invention is in seeing that the passengers are not only at excessive speed in the downward direction, in Extreme case with the impact of the elevator car in the Pit are protected, but also at comparable extreme movements of the elevator car in Upward direction. The passengers will be without them immediately protected.
  • the space-saving Safety device can be based on the driving data in time before the elevator car is in danger of impact, to be triggered.
  • Fig. 1 shows an elevator car 1 with one Cabin ceiling 2 arranged safety device 3.
  • the Elevator car is suspended on a suspension cable 4 and is up and down in an elevator shaft, not shown moves, with passengers 5 and / or objects from Floor to floor to be transported.
  • FIG. 3 shows the elevator car 1 with an example arranged on a cabin wall 9 safety device 3 with a trigger device 10 and a memory 11 snippets 12 serving as buffers for passengers 5.
  • a trigger device 10 and a memory 11 snippets 12 serving as buffers for passengers 5.
  • Fig. 4 shows the activated safety device 3 for Protection of passengers 5 in extreme situations Elevator car 1 in the downward direction or to protect the Passengers 5 after an extreme situation in the elevator car 1 in the upward direction.
  • Elevator car 1 in the downward direction
  • Passengers 5 Due to the extreme delay of the Elevator car 1 actuates the release device 10 Memory 11, the snippets 12 abruptly on the Cabin floor 8 are spread out. The on the passengers 5 acting forces become soft Underlying snippet 12 largely included.
  • the after an extreme situation of the elevator car 1 in Falling upwards from the cabin ceiling 2 Passengers 5 are caught by the snippet blanket and remain unharmed.
  • Fig. 5 shows an embodiment of the Safety device 3 with airbag 7 and one mechanically responding to extreme deceleration of elevator car 1 Release.
  • the example shows that according to FIGS. 1 and 2 the safety device 3 arranged in the cabin ceiling 2.
  • a permanent magnet 13 is on a deformable Bracket 14 arranged.
  • the permanent magnet 13 moves becomes.
  • the field lines intersecting the conductors of the coil 15 of the permanent magnet 13 induce an electrical Current in the coil 15, which serves as an ignition Resistance wire 16 flows.
  • the Resistance wire 16 becomes a resistance wire 16 surrounding pyrotechnic substance 17 ignites, the Substance 17 forms gas by chemical reaction, which the folded airbag 7 immediately and completely fills.
  • a valve instead of Permanent magnet 13 a valve can be operated, the one Pressure accumulator opens, the pressure medium of the airbag 7 fills.
  • Fig. 6 shows an embodiment of the Safety device 3 with airbag 7 and sensors for Acquisition of driving data.
  • an electrical one Memory 18 for example, a capacitor provided is discharged via the resistance wire 16 and the Fabric 17 ignites. The discharge is done by means of a switch 19 triggered, which is switched on or off by a limit value unit 20 is turned off.
  • An acceleration sensor 21 detects the acceleration or deceleration of the elevator car 1 and forwards its signal a to the limit value unit 20.
  • limit value unit 20 there are limit values for the Acceleration or for the speed of the Elevator car 1 set and if the signals of the Sensors 21, 22 will exceed these limit values Switch 19 closed.
  • a validation unit 23 checks the speed signal v and the acceleration signal a mutual on their trustworthiness.
  • the trigger device 10 is at the end of the blowpipe 29 a pyrotechnic substance. With ignition for example according to FIG. 5 or FIG. 6 of the substance expanding gases that generate kinetic energy to the Transfer snippet 12 and this for ejection in the Accelerate elevator car 1.
  • a protective grille 30 protects the snippets 12 located in the warm gas stream before severe warming. In the idle state, a prevents the other end of the blowpipe 29 arranged retaining disc 31 the exiting of the snippets 12 into the elevator car 1. If there is overpressure on the blowpipe side, it breaks Retaining disc 31 through.
  • Fig. 9 shows the arrangement of the blowpipes 29 on the Elevator car 1. With the arrangement of several blowpipes 29 on the elevator car 1 is a uniform distribution of the Scraps 12 achieved, making the current location of a Passenger in an extreme situation no longer Meaning is.
  • FIGS. 10 and 11 show an embodiment with a Compression spring 32 as a pressure medium for the in a container 33rd arranged snippets 12.
  • a Compression spring 32 as a pressure medium for the in a container 33rd arranged snippets 12.
  • the retaining disc 31 by means of the trigger device 10 for example, moved up pyrotechnically, whereby the Container 33 is opened on the cabin side and the snippets 12 are immediately ejected into the elevator car 1.
