Patent number: 8807195Abstract: The invention concerns a device with a curtain which can be rolled up and unrolled between a shut position and an open position, whereby this curtain (1) comprises a belt (2,3) on each of its faces, whereby each belt (2,3) has successive teeth (5,6) in the longitudinal direction, whereby these belts (2,3) are situated opposite one another in such a way that they can mesh when the curtain (1) is being rolled up. At least one of these belts (2,3) comprises teeth (5,6) having at least one recess (8,9) in which at least one protruding part (10,11) of the teeth (5,6) of the other belt (2,3) can engage in such a way that the two belts (2,3) can mesh and such that one of these belts (2,3) can push the other belt (2,3) in their longitudinal directions.Type: GrantFiled: January 31, 2008Date of Patent: August 19, 2014Assignee: Dynaco Europe NVInventor: Benoit Coenraets

Patent number: 8672014Abstract: The invention concerns a device with a curtain (2) that can be rolled up and unrolled between a shut position and an open position comprising, near the lateral edges (3) on each face, a serrated belt (1,6) extending parallel to said lateral edges (3), whereby each of the belts (1,6) has successive teeth (5,8). The lateral face of the teeth, extending in the longitudinal direction of the corresponding lateral edge (3) of at least one of the belts (1,6) provided on a face of the curtain (2) rests on a supporting element when the curtain (2) is rolled up. This supporting element is provided on the other face of the curtain (2).Type: GrantFiled: January 31, 2008Date of Patent: March 18, 2014Assignee: Dynaco Europe NVInventor: Benoit Coenraets

Patent number: 8341885Abstract: System for controlling a door enabling driving from an initial position of its travel in a first direction at a speed v1 as far as a final position, said control system comprising a safety function comprising means for keeping a door in operation despite its having suffered an impact against an obstacle situated on its travel and enabling it to continue its initial movement automatically as soon as said obstacle is removed, through a design reconciling a sufficiently high normal speed of movement v1 of the door with the intention to prevent damage both to the obstacle and to the door by reducing the speed to v3<v1 close to the stored position of the impact.Type: GrantFiled: September 23, 2010Date of Patent: January 1, 2013Assignee: Dynaco EuropeInventor: Frédéric Bostyn

Patent number: 8272425Abstract: The invention relates to a flexible shutter device, designed for closing a bay or other opening which cooperates with drive means which permit a displacement of the flexible shutter between an open position and a closed position. The device comprises a drum which may turn about the axis thereof and about which the flexible shutter is wound in the open position thereof, forming a roll comprising turns made up of successive layers attaching one to the other and from which the flexible shutter can be unwound and pushed into the closed position thereof. Slides mounted on a fixed support provide guidance along the bay for the unwound part of the flexible shutter. Pressure or restriction elements (33, 50, 66) avoid buckling of the lateral edges (2,3) in the supported part thereof, extending between a first end (30) of the slides (4,5), nearest the roll and the roll.Type: GrantFiled: February 4, 2008Date of Patent: September 25, 2012Assignee: Dynaco EuropeInventor: Benoit Coenraets

Patent number: 8109317Abstract: Device with a shutter and element for the reinsertion of a shutter into a guide slide. Device with a shutter for the closing-off of a bay (1), comprising a slide (7, 8); a deformable shutter (3) comprising a lateral flange (10, 11, 27) which is mounted slidingly in the slide; and a means for reinserting the flange into the slide, after it has been pulled out of the slide, this means comprising at least one pair of rollers (17) which are placed on either side of the shutter and which, while the shutter is moved opposite the bay in order to uncover the latter, roll on the flange which has come out of the slide and push it back into the latter.Type: GrantFiled: June 13, 2008Date of Patent: February 7, 2012Assignee: Dynaco EuropeInventor: Frederic Bostyn
