Abstract

The safety device is for the automatic shutting mechanism of building doors, each such mechanism having a shoe on the free end of an arm and sliding in a guide in the door lintel. It comprises an electrical circuit with a DC source and one or more damage detector switches opening when damage occurs. Each door has a micro-switch (20-22) closed by the shoe (7) when the door is wide open, so as to excite an electromagnet holding the door open. The door is held wide open only as long as the electromagnet is excited.
