Patent attributes
The invention relates to a shutter device intended to close a bay (6) or other opening, with flexible edges (2, 3) projecting with respect to the plane of the shutter (1) and collaborating with guideways (4, 5), at least one reintroduction element (12) being provided, allowing the said edges (2, 3) to be reintroduced into the guideways (4, 5) when these edges (2, 3) become disengaged from the latter under the action of a force exerted on these edges (2, 3) in a direction transverse to the guideways (4, 5), a contact area (37) being formed during this reintroduction between the reintroduction element (12) and the corresponding edge (2, 3), characterized in that the lateral edges (2, 3) consist at least partially of an elastomeric material so that the said contact area (37) increases as the said force increases, spreading this force over the contact area (37).
