Definitions

  • the present invention relates to an emergency call switch for a hazard detection system with an adjustable between a rest position and an alarm position or fragile trigger element for the operation of an alarm triggering switch, the trigger element carries an alarm indicator or is connected to such.
  • the trigger element is pivoted by a relatively small angle upon actuation of the emergency call switch, whereby on the one hand released the switch and on the other hand, not visible in the rest position alarm indicator is pivoted into the viewing window of the emergency call. Because of the relatively small pivoting angle of the triggering element in the operation of the emergency call switch, the alarm display formed by a title block is relatively small and therefore not easily recognizable. In addition, it can not be ruled out that the triggering element canted during its pivoting, which means a certain susceptibility to failure of this emergency call switch.
  • a first preferred embodiment of the emergency call switch according to the invention is characterized in that the front element is made opaque with the exception of at least one transparent area.
  • a second preferred embodiment of the emergency call switch according to the invention is characterized in that the at least one transparent area is formed by conventional display symbols, in particular a circle and two arrows directed against them.
  • a third preferred embodiment of the emergency call switch according to the invention is characterized in that the front element consists of a transparent material which is printed flat on one side and which is not printed at the location of the at least one transparent region.
  • a fourth preferred embodiment of the emergency call switch according to the invention is characterized in that the rear element has two color-different areas, one color representing the normal state and the other color representing the alarm state of the emergency call switch and being visible in each case by the at least one transparent area of the front element, and that the change from normal state to alarm state and vice versa by a corresponding displacement of the front element takes place.
  • a fifth preferred embodiment of the emergency call switch according to the invention is characterized in that the front element forms an integral part of the triggering element and is displaced upon actuation of the emergency call switch or upon its return after actuation.

  • a carriage-like release element 9 is mounted vertically displaceable, which is by pressure from the front to its center of the bendable and then returns to its rest position.
  • the trigger element 9 is guided by means of guide lugs F on the left and right side wall 6 of the lid 2 and additionally by means of guide grooves 10 secured to the cover plate 5 guide pin 11, which simultaneously limit the stroke of the trigger element.
  • a spring 12 is arranged, which presses the trigger element in the direction of arrow A downwards.
  • the triggering element 9 is opaque and has three transparent regions 13 in the form of symbols common in manual fire detectors.
  • the trigger element 9 is made of a transparent material which is printed on the front or back outside the transparent areas with a color.

Abstract

Le bouton d'appel d'urgence présente un élément déclencheur (9), pouvant être rompu ou déplacé entre une position de repos et une position d'avertissement, lequel élément permet l'enclenchement d'un bouton déclenchant une alarme. L'élément déclencheur porte un indicateur d'alarme ou est relié à un indicateur de ce type. Deux éléments plans superposés, mobiles l'un par rapport à l'autre, sont prévus, éléments parmi lesquels celui de derrière est fixe et pourvu d'un indicateur d'alarme et celui de devant, faisant face à l'observateur, peut effectuer un mouvement linéaire. Lors d'un déplacement linéaire de l'élément de devant, l'indicateur d'alarme de l'élément de derrière est visible. De préférence, l'élément de devant fait partie intégrante de l'élément déclencheur (9) et est déplacé lorsque le bouton d'appel d'urgence est enclenché ou lorsque ce dernier retourne à sa position initiale après avoir été enclenché. L'élément déclencheur (9) est constitué par un coulisseau mobile et pressé élastiquement contre une bascule (20).
