Gate leaf i.e. firestop, for use in door of building e.g. hospital, has main faces extending with respect to each other with given thickness, and section fixed at door using fixation system

摘要

The leaf has two main faces (8, 9) extending with respect to each other with given thickness (d), where the faces are connected by two vertical edges (12, 13) and two horizontal edges. A pivoting system pivots with respect to a frame. A section (I, II) of an L-shaped section comprises a overlap wing (25) that extends at right angle by a fixation wing (30) covering the vertical edges along width lower than the thickness of the leaf, where the section is fixed at a door using an fixation system (33).
