Abstract
Closing, separating or covering device comprising a blind (1) capable of being wound about a winding axis with flexible lateral edges (2) held in position in guide tracks (3) during winding and unwinding, wherein the latter (3) are elastically mounted on a support or rotatably mounted about an axis substantially parallel to their longitudinal axis such that the said lateral edges (2) can be held in position in the guide tracks during the displacement by rotation and/or translation of the latter in relation to the support (4).
Claims15
A closing device comprising a blind (1) having flexible lateral edges (2) each held in one of a pair of elongated guide tracks (3), each of said tracks having opposing sides and being mounted on a respective one of a pair of supports (4) in an elastic manner and pivotable about an axis essentially parallel to their longitudinal axis in such a way that tension exerted by said blind on the guide tracks is always divided substantially equally on both sides of said guide tracks with respect to the blind;
- and said guide tracks being capable of undergoing simultaneous translation and pivoting when operational.
A closing device comprising a blind (1) having flexible lateral edges (2) held in guide tracks (3), wherein said blind (1) has a narrow zone (33) of low strength, located between a lateral edge (2) and the surface of the blind itself (1), extending over the whole length of said edge (2), said zone (33) yielding as soon as the force acting on the surface of the blind (1) reaches a predetermined value, which is less than forces necessary to free the edge (2) from the guide tracks (3).
