Definitions
- the present invention relates to a device for unlocking a locking means, more in particular of a door, whereby the locking means is provided with a sliding bar or sliding pin, of which one end in the locked position has been introduced into a recess, more in particular arranged in a door frame or door sill.
- the free side of the door supports a laterally displaceable edge element which mates with either an adjacent door or a door frame when the door is in its closed position.
- the door may further have a bolt at the top of the door and a latch at the bottom of the door to lock the door to the door frame, and an operating handle is mechanically connected to the edge element to disengage it from its mating part and may simultaneously disengage the top bolt and bottom latch whereby the door can be opened. With this door the unlocking of the door takes place manually by pressing an actuating handle.
- FR-A-2294302 discloses a door which is provided with conventional means for locking the door.
- this conventional means for locking the door is unlocked by the personnel, but the door is then held in a locked position by means of a holding magnet provided at the door frame, which holds a bar mounted at the edge of the door.
- the bar may hinge around a hinge point away from the magnet, whereby the door may be pushed open.
- the unlocking device is characterized, in that this device is provided with a holding magnet by means of which an armature is held in a rest position, and which armature is connected to a striking element that co-operates with a projection mounted onto or connected to the sliding bar or sliding pin, and whereby the striking element in the rest position is spaced from the projection, such, that when the excitation of the magnet ceases to exist, the striking element is moved under weight and or spring force with a blow against the projection, thereby knocking the sliding bar or sliding pin out of its co-operating recess.
- the invention provides a greater safety for the public, that in a panic situation will have to be able to open quickly the locking means through which it wants to move.
- the armature and the striking element are mounted onto a hinged lever, whereby this hinged lever supports the armature on the one end and the striking element on the other end.
- unlocking device is characterized in that a weight and/or a spring is mounted underneath the armature.
- the end of the sliding bar or sliding pin 1 finds itself in the locked position of the locking means within the recess 2.
- the unlocking device is provided with a holding magnet 3.
