Protection device for protecting access to room through opening outside of building, has shutter forming screen to opening, and delimiting chamber for access to room, where chamber extends between protection assemblies

摘要

The device has a protection assembly (4) including a door (5) provided with a locking unit (6). Another protection assembly (7), structurally independent of the former protection assembly, includes a frame (8) carrying a motorized shutter (9), where the frame includes anchoring units (12) for anchoring the frame to a ceiling (14) and a floor (13). The shutter forms a screen to an opening (2), and delimits a chamber (35) for access to a room, where the chamber extends between the protection assemblies while being closed by partitions (31) placed laterally between protection assemblies. An independent claim is also included for a method for implementing the protection device.
