DEVICE CONCERNING A SAFETY DOOR, OPENABLE BY DIGICODE OR OTHERWISE. IT OFFERS A SIGNAL IN PERMANENT SLEEP IN THE EVENT OF AN INTRUSION ATTRACTION BY THE CLOSING COAST

摘要

The present invention relates to a device for unlocking a door without lock, by the introduction of an electric message that makes active opening handle that turns on itself in the absence of the message. On the other hand, the sliding bolts in closed mode penetrate in bridges held by elastic studs which are compressed in case of pressure on the door. The trigger guard then approaches a contact that triggers an alarm as soon as the trigger guard touches it. The unlocking is obtained by driving the axis 5 by the handle 6 of the door 1 once the code entered. The electromagnets 17 and 18 place on them the disk 16 integral in rotation with the axis 5 and having a play in the axial direction. The part 11 is driven by the disk 16. The cables 21/22 are pulled and retract the sliding bolts 24 which unlock the door 1. The sliding bolts 24 remain open by the action of an electromagnet 25 which is actuated as soon as door 1 opens. In the closed position, the sliding bolts 24 are introduced under bridges 21 pressed against the doorframe 32 by elastic studs 33. In the event of significant force on the door 1, the elastic studs 33 are compressed, the bridges 31 recede, touch a contact screw 38, isolated from the blade 34 by a wire pass 37, and trigger an alarm.
