| 20090302617 | SAFETY INTERLOCKING DEVICE WITH ESCAPE UNLOCKING MEANS - A safety interlocking device has a locking unit for mounting on the safe side to a door relative to a hazardous region, and a locking cage for mounting on a door frame interacting with the door. In order to be able to open, from the hazardous region, the locked door and escape from the hazardous region, an escape unlocking device is provided for unlocking the safety interlocking device. The locking cage has a locking stop which is articulated to a base plate so as to be able to pivot about a pivot axis from an interlocking position into an emergency opening position. The escape unlocking device possesses at least one arresting tip which, in an escape position, releases the locking stop for pivoting into the emergency opening position. Provided between an emergency handle and the arresting tip is a stretched rod piece which is embodied so as to be displaceable together with the arresting tip. In the normal position of the escape unlocking (EU) device, the arresting tip is in arresting operative connection with a first arresting surface of the locking stop and a second arresting surface of the base plate. At least one of these operative connections can be released by displacement of the arresting tip in the rod direction. | 12-10-2009 |
