Height and width adjustable metallic safety door structure for e.g. preventing access to unauthorized person, has sliding parts moved vertically and laterally in support frames due to auger permitting to completely block secured openings

摘要

The structure has support frames (3, 3b, 4, 4b) in which a door panel is mounted on pivots (9, 9b) that are installed at top, bottom and lateral sides in a lintel and/or applied to the lintel or a steel framework of a door. Adjustment in height and width of the structure is obtained using sliding parts (1, 1b, 6) of the framework through an auger (10). The sliding parts are slided in U-shaped pieces (2, 2b, 5), and are moved vertically and laterally in the frames due to the auger permitting to completely block secured openings.
