<p>The closure door (100) has an element (110) including a plate of constant thickness delimited by an upper wall and a lower wall, and another element (130) including a pair of parallel walls joined together locally by a junction area. The elements are slidably mounted to each other so as to change the width of the closure door. A slide (140) covers one of the walls of the latter element, where the slide is bordered by a rounded wall that accompany movement of a curtain (T) in a tunnel-shaped casing (CT). An independent claim is also included for a tunnel-shaped casing.</p> |
