Title (EN) BLIND OR CURTAIN
(FR) STORE OU RIDEAU
Abstract:
(EN) A roller blind intended to be placed over an existing window so as to redirect light impinging thereon from the window includes an inner surface formed of a plurality of elongate prisms. The orientation of the prisms is such that light from the sky above the window is reflected into a room rather than immediately towards the floor. Each prism may have a width of up to approximately 100 micrometers. The angle of the operative surface of each prism can be chosen in dependence upon in particular effect sought, although it is preferably 45° or more relative to the plane of the blind or curtain when in use.
(FR) On décrit un store roulant qui s'intalle au-dessus d'une fenêtre de manière à réorienter la lumière qu'il reçoit depuis la fenêtre. Ledit store roulant inclut une surface interne constituée d'une série de prismes allongés. L'orientation des prismes est telle que le rayonnement solaire au-dessus de la fenêtre est réfléchi à l'intérieur d'une pièce plutôt qu'il n'aille directement vers le sol. Chaque prisme peut avoir une largeur pouvant atteindre approximativement 100 micromètres. L'angle de la surface utile de chaque prisme peut être choisi en fonction, notamment, de l'effet recherché, bien que cet angle doive être, de préférence, supérieur ou égal a 45° relativement au plan du store ou du rideau pendant le fonctionnement.
