Definitions

  • the invention relates to a bolt switch for locks and / or locking bolts of protected and monitored doors and windows with a reed contact arranged in a switch housing and a magnet which is arranged displaceably with a movable switching lever.
  • bolt switches are used for intrusion protection to monitor protected doors and windows on the locks.
  • Known latch switches are generally quite large and therefore make assembly on a lock or on a window latch difficult.
  • An assembly with the bolt switch previously used is very difficult or sometimes even impossible with a so-called hollow assembly, ie without a removable striking plate.
  • many of the well-known latch switches are sensitive to moisture, particularly condensation, when the latch switches have to be mounted on windows or external doors. This can often cause interference. Therefore, reed contacts are used in known bolt switches, which are hermetically sealed and thus ensure greater functional reliability.
  • installation is often difficult here, too, because the relatively large dimensions do not allow easy installation. In particular, installation on the door lock between the latch and bolt is not possible with the conventional door locks.
  • the object of the invention is to design a bolt switch with a reed contact so that the bolt switch has a relatively small volume and a reliable switching point, which should be reached relatively early when locking.
  • the form-fitting link control with the eccentric on the shift lever for moving the ring magnet achieves a significantly lower overall height than, for example, a bolt switch which has a non-positive cam control with a compression spring.
  • the bolt switch according to the invention therefore has the advantage that it easily between the latch and the bolt of a common door lock can be installed.
  • the bolt switch according to the invention can also be used for so-called hollow mounting without any problems, both for doors without a striking plate and in the window frame for window monitoring, so that only one switch design is required for intrusion protection.
  • the pivotable switching lever is expediently pivoted out when the reed contact is not switched. It is thus in its initial position and is actuated when locking with the locking bolt so that it can pivot into its end position.
  • lever deflection with an angle of only 10 ° is advantageously sufficient to effect the necessary stroke so that the reed contact can be actuated, i.e. so that it reaches its switching point early.
  • a mounting plate for mounting the latch switch is floatingly mounted in the switch housing, so that a height adjustment of more than ⁇ 2 mm is ensured when the latch switch is installed. This enables an optimal setting of the bolt switch.
  • the latch switch according to the invention is briefly explained with the aid of the drawing.
  • Fig. 1 the latch switch is shown in plan view, partially in section.
  • the cylindrical housing for the reed contact is arranged, in which the reed contact 2 is located, which is not specifically shown.
  • the reed contact housing 5 is from Ring magnet 3 enclosed.
  • the ring magnet 3 is connected to the sliding block 6, which has a recess 7.
  • the shift lever 4 is indicated in two positions, on the one hand in the swiveled-out position a and on the other hand in the end position e when it has been swiveled by the locking bolt.
  • the shift lever 4 is mounted in point 1a.
  • the shift lever 4 has the eccentric 8, which pushes the ring magnet 3 upwards when pivoting by means of the positive-locking link control.
  • a fastening plate 9 with two threaded bores 9a is arranged in a floating manner in the bolt switch, so that a height adjustment h of at least ⁇ 2 mm is ensured. This enables the bolt switch to be optimally positioned during assembly.
  • the two connecting wires 2a leading away from the reed switch 2 are soldered to two soldering support points 10, of which only one is visible.
  • pivoting the switching lever 4 by an angle of ⁇ 10 ° is sufficient to achieve the necessary stroke H, so that the reed contact 2 switches safely and relatively early by the ring magnet 3. This is illustrated in Figure 3.
  • Fig. 2 shows a diagram in which, depending on the angle, the stroke H is plotted in previous bolt switches.
  • a desired stroke H of, for example, approximately 0.5 mm the switch-on point E is only reached when the deflection angle ⁇ of the shift lever reaches 30 °.
  • Fig. 3 it is shown in the diagram that the bolt switch according to the innovation already reaches its switch-on point E at 10 °.
  • the stroke H is plotted over the deflection angle ⁇ .
  • the switch-on point E is at a stroke H of approximately 0.5 mm 10 ° reached. This early reaching of the switching point of the reed contact ensures a reliable switching of the bolt switch when the door or window is locked.
