Definitions

  • the present invention relates to a device for triggering a complementary warning system signaling the defectiveness of a safety warning light, in particular for an elevator, which indicator is mounted on a plate integral with the door frame and connected to an electronic circuit detecting the defect.
  • the indicator lights are easily vandalized and thus not only disturb the proper functioning of the installation, but also call into question the safety of people.
  • the indicator indicating on the landing the presence or not of the cabin on the floor.
  • a user may then make a fatal drop in the sheath by opening a previously forced door and poorly locked, while the cabin is not present.
  • the purpose of the present invention is to meet this standard, and for this purpose concerns a device for triggering a complementary warning system signaling the defect of a warning light, in particular for an elevator, which indicator is mounted on a plate and connected to an electronic circuit for detecting the defect, characterized in that the indicator light is mechanically associated with the electronic circuit against which it bears freely, directly or indirectly, the subassembly thus formed also bearing freely on the inner periphery a hole formed on the plate in which is housed the apparent light portion of the witness, by means of fixing means, so that any external mechanical action exerted on the witness, beyond a determined force corresponding to a burglary, causes repercussion a break or a short circuit of the printed circuit, and consequentmen t triggering an additional audible and / or optical alarm.
  • the present invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.
  • the indicator light 1 is integral with the plate 2 and is intended to be fixedly applied to a frame 3 of an elevator landing door 4.
  • the indicator light 1 is associated with a trigger device 10 of a complementary warning system 11 signaling any defect in the indicator 1, door indicator open, except the presence of the cabin on the floor, and connected to an electronic detection circuit 12.
  • the indicator light 1 is mechanically associated with the electronic circuit 12 against which it bears freely, directly or indirectly, the subassembly thus formed also bearing freely on the inner periphery 13 of a hole 14 formed on the plate 2 in which is housed the apparent light portion 15 of the control 1, by means of fastening means 16, so that any external mechanical action exerted on the control 1, beyond a determined force F corresponding to a burglary, causes by repercussion a break or a short circuit of the printed circuit 12, and consequently the triggering of an additional audible and / or optical alarm 17.
  • the indicator light 1 is placed in free abutment against the inner peripheral zone 13 of the hole 14 of the plate 2 by means of two diametrically opposite lugs 18 formed on the upper periphery of the witness 1 which are traversed by fixing screws 16 from the plate 2, at opposite ends of which is fixed the electronic circuit 12 by means of two spacers 19 interposed between said circuit 12 and the legs 18 of the control 1 so that breaking them during a break-in consequently causes that of the electronic circuit 12 on which is bearing the control 1, or its short-circuit.
  • the indicator light 1 has a hollow body 20 in which is freely slidable a cap 21 also hollow whose apex 22 is disposed in the immediate vicinity of the face 15 of the control 1, said cap 21 comprising at its lower peripheral end a flange 23 freely interposed between the lower peripheral end of the body 20 of the control 1 and the electronic circuit 12, so that a break in the indicator light 1 made by a force F insufficient to damage its legs; support 18 nevertheless causes the displacement in translation of the cap 21 alone against the electronic circuit 12 to break.
  • the cap 21 is immobilized in rotation by a lug 24 penetrating into a housing 25 of the body 20 of the control 1.
  • the spacers 19 providing the mechanical connection between the electronic circuit 12 and the lugs 18 of the indicator light 1 as well as the free bearing of these against the plate 2, are elastically deformable in compression, so as to that any action brought by break-in on the indicator light 1 allows its movement in translation towards the electronic circuit 12 to break it, by means of the cap 21 or not, by breaking or not the tabs 18.
  • the struts are elastically deformable in compression consist of spiral springs.
  • the electronic circuit 12 has a zone of weakness 26 situated opposite the indicator light 1, so as to promote the breakage of said circuit 12.
  • the bleeding 26 constitutes a rupture primer.
  • the electronic circuit 12 comprises in particular a light bulb 27 housed in the light 1, as well as a sound alarm 17, associated with various electronic components, via conductive tracks of a printed circuit 12, the breaking of a of these 28 having the effect of activating the supplementary alert system 11.
  • the electronic circuit 12 comprises in particular a light bulb 27 housed in the light 1, as well as a sound alarm 17, associated with various electronic components via conductive tracks of a printed circuit 12, the short circuit of one of the electrical or electronic components causing the rupture of a fuse F1 of the complementary warning system 11 and consequently triggering.
  • the audible alarm 17 is disposed on the electronic circuit 12, above a perforated area of holes 29 of the plate 2, so as to allow the passage of sounds, while avoiding said alarm 17 to be reached by projections or infiltrations of water.
  • the entire device 10 is protected by a cover 30 fixed to the rear of the plate 2 having plumb with the perforations 29 of the plate 2, a drain hole 31 of the water, made in a lower zone. of the hood 30.
  • the plate 2 thus equipped is fixed on the frame 3 of the door 4 by means of studs 32.
  • the track 28 of the printed circuit 12 provides the connection between an input TP4 and an output TP5 of a negative voltage.
  • TP4 being connected on the point 2 of a terminal 33 and TP5 being connected on the point 3 of said terminal block.
  • the octocoupler OK1 Since it no longer has a negative voltage continuity at the input of the octocoupler OK1, the latter causes the state of the transistor T1 to change, which then sends a positive voltage in the track 32 and therefore causes the supplying the coil of the relay K1 and the transistor Q1, this having the effect, on the one hand, of changing the state of the "alarm report” contacts X12 and those of the "security chain” X7, and on the other hand to feed the alarm 17 (B22) and the flash light connected to X4 and consequently to warn of the break-in on the indicator light 1.
  • the same final result is also obtained, if during the break-in a short circuit is caused either for example by the rupture of the bulb 27, or by any other connection of the positive voltage with the negative voltage.
  • This short circuit then causes the breaking of the fuse F1 and therefore the discontinuity of the negative voltage at the input of the octocoupler OK1.
  • the situation is then identical to that described above and concludes with the expected final result, namely to trigger the additional alert 11, in case of break-in.
