Abstract:
A metal frame for the metal door leaf of a door comprises: a first metal jamb (1) and a second metal jamb (2) which (1, 2) extend vertically and delimit the passage opening of the door laterally, and at least one metal header (3) which (3) extends horizontally and is fixedly connected to each of the jambs (1, 2), wherein the header also delimits the passage opening of the door. The first jamb (1) has a first connecting bracket (1a) at one of its ends, and the second jamb (2) has a second connecting bracket (2a) at one of its ends, wherein each of the two connecting brackets (1a, 2a) has a vertically upwardly directed insertion opening. In addition, the header (3) has, at one of its two ends, a first connection portion (4) intended to be inserted into said first connecting bracket (1a) and, at the other of its two ends, a second connection portion (5) intended to be inserted into said second connecting bracket (2a). If the header (3) and the two jambs (1, 2) are in a mutually connected position, the first connection portion (4) is arranged in the first connecting bracket (1a), and the second connection portion (5) is arranged in the second connecting bracket (2a) and the insertion, through the associated insertion openings in the two connecting brackets (1a, 2a), of the two connection portions (4, 5) into the associated connecting brackets (1a, 2a) has taken place due to the translation of the header (3) along the vertical.
