Definitions

  • the present invention relates to a device for burglary alarm protected doors, intended to prevent unintentional false alarm indication.
  • a device for this purpose is previously disclosed in SE, A, 419 879, and includes a movable slide member located by the outside door plane, in a first position located extending across a key hole for a lock mechanism arranged in the door, being manually movable to a second position, in which the key hole is uninterruped and free.
  • An electromagnet connected to the alarm circuit, locks the slide member in the position extending across the key hole when the alarm system is switched on, thereby preventing unintentional unlocking of the door when the alarm system has not been disconnected.
  • a disadvantage with this previously known device is that the electromagnet in locked position receives its voltage supply from the alarm circuit, and an alarm circuit must be operable for a long period of time after an interruption of the mains voltage supply, during which time period voltage is supplied from electric accumulators.
  • existing standby power must be dimensioned considering the power consumption of the electromagnet, which results in a larger number of electric accumulators being required, and thus also an increased cost for standby power, and same also requires an increased space.
  • it has therefore been proposed examples of embodiments in which the electromagnet causes a locking action when no voltage is supplied, releasing the slide member from locked position when a voltage is supplied.
  • such an embodiment involves voltage feed from an independent supply circuit, and this supply circuit must be switched via the alarm circuit, which involves additional wiring, separate voltage source, and special switching equipment for switching a relay on/off.
  • the object of the present invention is to overcome the disadvantages associated with the previously known device.
  • An installation with voltage supply from the alarm circuit is also advantageous, both with regard to simplified installation and lower cost, but has not previously always been possible, due to existing regulations relating to standby power in case of mains supply interruption. According to the present invention, it is now possible to obtain such a simplified installation, without increasing the power consumption of the alarm installation.
  • the device includes a displacably arranged slide at the outer plane of the door, arranged to be secured in a position extending across the key hole of the lock mechanism by means of influence from an electromagnet when the alarm circuit is switched on, and is mainly characterised in that the slide is arranged to influence an electrical switch means when in a position extending across the key hole, and thereby interrupt a voltage supply from the alarm circuit to the electromagnet, and that a first displacement movement of the slide in direction from the key hole is arranged to make the switching means close the voltage supply to the electromagnet from the alarm circuit, thereby causing the electromagnet to lock the slide aga-inst further displacement movement intended to open the key hole.
  • the slide is arranged to return from a position locked by the electromagnet to a position influencing the electrical switching means under influence of a return spring member or similar, thereby interrupting the voltage feed from the alarm circuit to the electromagnet.
  • the device shown in Figs. 1 - 5 includes a base part 1, intended to be attached against an outer door surface by means of screws or similar. With regard to the portion of the base plate 1 having a larger width, same is intended to be covered by a protective housing in use, but in order to simplify the disclosure, said housing is not shown.
  • the narrow portion of the base plate 1 is arranged with a through slot 2, which when attached is located over the key hole to be protected (indicated by broken lines in Fig. 4).
  • a longitudinally extending slide member 3 is displacably arranged in relation to the base plate 1, partly covered by a supporting plate member 4 attached against the wider portion of the base plate 1.
  • the supporting plate member 4 which advantageously may comprise of a circuit board arranged to support and electrically interconnect utilized components, is arranged with a through slot 5, extending in the direction of movement for the slide 3.
  • An abutment means 6 extends upwards from the slide 3 through the slot 5, preferably having the free end portion enlarged by means of a folded portion, as shown in Fig. 3.
  • the plate member 4 supports a relay 7, but also an electrical switch means 8, e.g. a micro-switch.
  • the armature of the relay 7 is designed as a longitudinally extending member 9, pivotably attached against an edge portion of the relay 7, and arranged having a substantially U-shaped locking member 10 attached to the free end portion.
  • a not shown return spring member is also arranged, acting on the slide 3 in such a manner, that same takes up the position shown in Fig. 1 when the slide 3 is not manually operated.
  • the not shown return spring member applies a pressure moving the slide 3 towards the end portion of the narrow part of the base plate 1, said movement being restricted by contact between the abutment means 6 against an end portion of the slot 5.
  • the abutment means 6 also takes up contact against a contact lever extending from the switch means 8, thereby influencing same into a non-closed position.
  • This position is also illustrated as a circuit diagram in Fig. 6, and results in no voltage feed to the coil of the relay 7. Accordingly, if the circuit shown in Fig. 6 is connected for voltage supply from an operative alarm circuit, no voltage is supplied in this position to the coil of the relay 7, and the device is thus not causing any power drain from the alarm circuit.
  • a rapid and distinct switching operation id obtained, thereby securing that the relay 7 can lock the slide 3 by moving the locking member 10 to a contact position against the abutment means 6.
  • the portion of the locking member 10 that contacts the abutment means 6 is preferably when uninfluenced, as illustrated in Fig. 1, arranged located adjacently in a sideway relationship to the slot 5, and at a small distance from the adjacent portion of the abutment means 6, in order to secure that the locking member 10 takes up intended position within the time period necessary for moving the slide 3 to the position in which same is locked.
  • the described and shown embodiment thus facilitates a locking action only when the alarm circuit from which voltage is supplied is switched on, and results in no power consumption when the slide 3 is not manually influenced.
  • a locking action does not occur when the alarm system is switched on, but only when the slide 3 is manually influenced, in order to open the key hole protected by the device.
  • Such an optical indication can also be arranged between the switch means 8 and the relay 7, thus resulting in optical indication only when the slide 3 is influenced, i.e. as further indication to the person trying to open the key hole that the alarm system is switched on.
  • an acoustic signal source e.g. a buzzer, can obviously also be used.
