Patent ID: 7416014

Claim:
Shutter device with a shutter intended to close a bay ( 6 ) or other opening, the shutter presenting a plane in a closed position, with flexible edges ( 2 , 3 ) protruding with respect to the plane of the shutter ( 1 ) and running in opposing guideways ( 4 , 5 ) having an upper part ( 11 ) and a lower part ( 13 ), at least one reintroduction element ( 12 ) being provided at the upper part ( 11 ) of at least one of the guideways, allowing the said edges ( 2 , 3 ) to be reintroduced into the guideways ( 4 , 5 ) during an upwards movement of the shutter when these edges ( 2 , 3 ) have become disengaged from the lower part ( 13 ) of the guideways under the action of a force exerted on these edges ( 2 , 3 ) in a direction transverse to the guideways ( 4 , 5 ), wherein this reintroduction element ( 12 ) has guide members ( 14 , 15 ) with rounded surfaces on their sides facing the lower part ( 13 ) and the at least one guideway respectively, the lateral edges ( 2 , 3 ) being guided by said rounded surfaces during reintroduction of the edges ( 2 , 3 ) into the guideways ( 4 , 5 ), whereby the guide members ( 14 , 15 ) press against the lateral edges ( 2 , 3 ) over a contact surface ( 37 ) between the guide members ( 14 , 15 ) of the reintroduction element ( 12 ) and the corresponding edge ( 2 , 3 ) during this reintroduction, wherein the lateral edges ( 2 , 3 ) consist at least partially of an elastomeric material so that the said contact surface ( 37 ) increases as the said force increases, spreading this force over the contact area ( 37 ).
