<p>The invention concerns a shutter for closing an opening (11), the shutter (1) having flexible lateral edges (5, 6) moving in guideways (7, 8), means being provided for releasing the lateral edges (5, 6) from their guideways (7, 8) when a certain tensile force transverse to the longitudinal direction of the guideways (7, 8) is exerted on said edges (5, 6), reinserting means being provided for re-engaging the edges (5, 6) in the guideways (7, 8). Said device is characterized in that said reinserting means comprise guiding members (20) arranged opposite the guideways (7, 8), so as to deflect the edges (5, 6) of the shutter (1) into the guideways (7, 8) when the shutter (1) moves upwards.</p> |
