The brace has a profiled plate (7) fixed to it and to the lower part of the leaf, the body being hollow to take the articulation axis of the brace. The body houses a pivoting spring-mounted profiled catch (10) that locks onto a finger (14) on an opposed base plate (13) in the lower part of the fixed frame, when the leaf is completely closed.</p> |
