Definitions

  • the invention relates to a manual hazard detector according to the preamble of claim 1.
  • detectors for one manual operation namely manual risk detectors, so-called "Push button” used.
  • Such detectors are usually produced in two versions.
  • Detector type B represents an indirect actuation, a so-called push button design.
  • the trigger element is the button (control element).
  • a so-called spring button design only has to the glass pane is broken in, then the jumps Button by spring pressure, i.e. is the trigger element from the disc (fragile element) plus the button (Control element) formed.
  • the Button movement an electrical switch actuates which the alarm message as an electrical signal to the hazard alarm system forwards. It is extraordinary it is important that these detectors function properly and are always ready for a safe alarm.
  • the object of the invention is manual risk detectors described above to further develop such that the switching or Actuation mechanism independent of mechanical friction forces and manufacturing tolerances a reliable alarm ensures and optionally in those described above Detector variants (type A or type B) can be used.
  • the manual hazard detector the housing of which is usually a Detector door, a fragile element and a detector insert which has a printed circuit board or a support element, at least one switch, one actuator with an associated compression spring and a
  • the trough has between the PCB or the support part and the tub one redesigned fastening mechanics by one Operating lever that is fixed on one side but rotatable is stored, a protruding through the tub Control button and on the other side a resilient element on which is a switch button of a switch assigned.
  • the invention has the advantage that the friction-dependent Force redirection at the switch button by 90 ° is eliminated because you a direct-acting friction and tolerance independent Has mechanics. Likewise, a safe one Switch actuation through a tolerance-independent button attachment and guidance possible.
  • the resilient element can expediently be of a Leaf spring be formed, which is attached to the control lever is.
  • the leaf spring can have a longitudinal section, so that the two leaf spring ends each have a switching element can operate.
  • the Control lever, the control element and the resilient element in one piece, e.g. be made of resilient plastic.
  • the resilient element of a multiple be angled spring plate formed by means of a Pivot bearing is attached to the operating lever.
  • Fig. 1 is the basic structure of a known Push button detector, i.e. a manual hazard detector for indirect actuation (type B) shown.
  • a manual hazard detector for indirect actuation type B
  • the push button 3 In the event of an alarm after breaking the glass pane 4 (fragile Element) the push button 3 in the direction of the arrow pressed. The slope 3a presses the push button 3 beveled switch button 5a and thereby triggers the alarm signal out.
  • FIG. 2 shows the basic structure of a known one Spring button detector (detector type A) for direct actuation shown.
  • the spring button 3 with the beveled Switching gate 3a is extended by a resilient pin 6a.
  • the spring pin 6a lies against the glass pane 4 and holds the jump button 3 in the pressed position so that the switch button 5a held in this standby position becomes.
  • the spring button 3 by the compression spring 6 pressed outwards in the direction of the arrow and the switch button 5a of the switch 5 released for triggering the alarm signal.
  • the manual hazard detector according to the invention has a newly designed one Actuation mechanism 19 on by the operating lever 9, the control element 3 and the resilient element, here a leaf spring 10 is formed.
  • a tub 7 is placed on the circuit board 8 with one or more pressure switches 5 - here two are shown - a tub 7 is placed.
  • the operating lever 9 is fixed on the upper side and rotatably mounted (9a).
  • the Leaf spring 10 made of spring plate is attached to the operating lever 9, for example with a snap connection.
  • a compression spring 6 holds the operating button or the control element 3, the control lever 9 and the leaf spring 10 in the rest position, i.e. the indirect operated detector is ready for operation in the rest position.
  • Control element 3 is in detector type A on the glass pane, i.e. on the fragile element 4 (Fig.).
  • the indirectly operated detector, type B, according to 5 the tub 7 forms the counterpart for the control element 3rd
  • actuation mechanism 19 in one piece, e.g. designed as a molded plastic part, i.e. the control lever 9, the control element 3 and that Resilient element 12 are made in one piece and form the actuating mechanism 19.
  • FIGS. 7a, 7b and 7c presented the invention. It is instead of the leaf spring 10 a spring plate 11 is provided according to FIGS. 4 and 5, that is rotatable on the operating lever 9 by means of a rotary bearing 9c is appropriate. In the form shown here, it can Only bend the spring plate 11 to one side.
  • Fig. 7a shows the basic structure
  • Fig.7b and 7c Function Fig. 7b
  • Fig. 7c shows the indirectly operated detector type B.
  • 8 and 9 are two different embodiments for a directly operated detector (type A).
  • 8 shows a so-called spring button detector, in which after breaking the glass pane 4 (fragile element) the compression spring 6 the spring button 3 (control element) in the direction of the arrow.
  • the leaf spring 10 is supported on the tub 7, whereby the free end 10a of the leaf spring 10 in the opposite Direction is moved and the pressure switch 5 on the circuit board 8 actuated, which leads to the alarm triggering.
  • high impact energy can cause it the operating lever 9 is also pushed in as far as it will go will.
  • An alarm is also triggered in this case, because the jumping button detector is also like a push button detector behaves.
  • the control lever fixed in the alarm position, but this is not shown is.
  • Fig. 9 shows a so-called tilting glass version.
  • Pressure on the disc 4 breaks it at the predetermined Predetermined breaking point 4a (scoring on the inside of the pane in Middle of the button) and tilts in the printing direction as shown.
  • the control button 3 and the leaf spring 10 in The direction of the arrow moves and the alarm is triggered.
  • This kind direct activity is in some European countries, such as Finland and England, common. For protection injuries can occur in all versions on the A transparent film on the outside of the detector 4b inserted or glued.
  • Fig. 10 there is again an indirectly operated detector, a so-called push button version (type B) is shown. After breaking the glass pane 4 and pressing the actuation button 3 presses the leaf spring 10 directly on the switch button 5a of switch 5 and triggers the alarm. The control lever 4 is then by a not shown here Bolt fixed in the alarm position.
