ABSTRACT:
The invention relates to a shutter device intended to close a bay (11) or other opening and able to experience a downwards and upwards movement, the shutter (1) having flexible lateral edges (5, 6) projecting with respect to the plane of the shutter (1) and roughly continuous running in guideways (7, 8) mounted on a fixed support (9), means being provided, at least in the region of the lower part of the bay (11) or the said other opening, for allowing the projecting lateral edges (5, 6) to disengage from their guideways (7, 8) as soon as a certain tensile force transverse to the longitudinal direction of the guideways (7, 8) is exerted on these edges (5, 6), reintroduction means being provided so as to allow the lateral edges (5, 6) to engage once again in the upper part of the guideways (7, 8) during the upwards movement of the shutter (1), this device being characterized in that the said reintroduction means comprise guide members (20) provided facing the guideways (7, 8) so as to divert the edges (5, 6) of the shutter (1) into the guideways (7, 8) during the upwards movement of the shutter (1).
