摘要

The door has a casement (2) with peripheral walls (13, 18) comprising inclined zones (14, 19) which extend in slanted manner with respect to a main plane (P) of the casement. The inclined zones (14, 19) cooperate with an inclined lateral wall (11) of a sill (10) and an inclined zone (20) of a frame (9), respectively. The zones form an angle with the plane, where the angle is lower than 90 degree and is not equal to zero.
