Definitions

  • the invention relates to a command and signaling element for lifts in explosive buildings, consisting of a pressure switch arranged in a housing with a light indicator.
  • a contactless push button transmitter with integrated incandescent lamp which is provided for lifts in explosive buildings is known, which has a transformer in the form of a magnetically non-conductive cylindrical double coil body with a primary coil and a secondary coil.
  • a magnetizable part is immersed in the double coil body, as a result of which the magnetic coupling between the primary coil, which is subjected to a low-frequency voltage, and the secondary coil is changed.
  • a voltage surge is generated, which is detected by a downstream evaluation circuit and passed on to the elevator control in the form of a voltage pulse.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a command and notification element that today's Lifts in potentially explosive buildings.
  • 1 denotes a first housing and 2 denotes a second housing.
  • a button 3 is arranged on the front of the first housing 1, into which a bar-shaped magnifying glass 4 is embedded over the entire width.
  • the button 3 is carried by a base plate 5 lying in the first housing 1, which has an inner actuating bracket 6.
  • the movement of the button 3 is transmitted via the actuating bracket 6 to a plunger 7 of an explosion-proof switch 8 fastened to the second housing 2.
  • the command triggered by a step function of the switch 8 is forwarded to the elevator control system via a first cable 9.
  • a compression spring 11 which is guided at one end in a second recess 10 and at the other end on the base plate 5, brings the key 3 back into the rest position.
  • the switching elements of the circuit arrangement according to FIG. 7 are arranged on a circuit board, not shown, which is held in the second housing 2 by guides, not shown. On the front of the second housing 2 there are light-emitting diodes 12; 13; 14; 15; 16 out. After the test and installation of the circuit board, the second housing 2 is cast with casting resin from the rear side.
  • the circuit arrangement according to FIG. 7 receives the light emitting diodes 12; 13; 14; 15; 16 control messages to be visualized via a second cable 17 from the elevator control.
  • a first recess 18 in the first housing 1 connects to the light-emitting diodes 12; 13; 14; 15; 16 on.
  • the first housing 1 has a collar 20 with holes on the front for fastening.
  • the housing 1; 2 are on mounting tabs 21; 22 screwed together.
  • a push button 23 is symbolized below the bar-shaped magnifying glass 4 with a circular depression in the button 3.
  • the remaining area on button 3 is intended for use-specific information such as floor numbers, door closing or door opening symbols etc.
  • the signaling element shown in FIGS. 4 to 6 as a variant of the command and signaling element is essentially constructed in the same way as the signaling and signaling element in FIGS of the first housing 1 fixed.
  • the area below the bar-shaped magnifying glass 4 is intended for use-specific information such as operating conditions, error or fault messages, etc.
  • the explosion-proof switch 8 is not required for the signaling element variant.
  • the circuit arrangement shown in FIG. 7 consists on the input side of a protective diode 25 connected to the anode at a terminal labeled +, the cathode of which is connected to a limiting resistor 26 and a parallel connection of two Zener diodes 27; 28 is connected. At the other end are the Zener diodes 27; 28 to a - designated terminal, the limiting resistor 26 to a two-branch, output-side parallel connection connected to the terminal - in connection.
  • the first branch of the parallel connection on the output side consists of a series connection of a first light-emitting diode 12, a second light-emitting diode 13, a third light-emitting diode 14, a fourth light-emitting diode 15, a fifth light-emitting diode 16, a first transistor 29 and an emitter resistor 30.
  • the output-side Parallel connection is a collector resistor 31 in series with a second transistor 32.
  • the base of the first transistor 29 is located on the collector of the second transistor 32.
  • the base of the second transistor 32 is located on the emitter of the first transistor 29.
  • the purpose of the parallel connection on the output side is at a strongly fluctuating input voltage U through the current the LEDs 12; 13; 14; 15; 16 to keep constant in order to ensure a constant lighting effect on the beam-shaped magnifying glass 4.
