Title (EN) A CONSTRUCTION FOR SUPPORTING A FLEXIBLE SHEET
(FR) STRUCTURE DE SUPPORT POUR PANNEAU FLEXIBLE
Abstract:
(EN) A construction for supporting a flexible sheet (56) is disclosed, which construction includes a U-shaped channel (34) having opposed flanges (40, 42) that are adapted to receive a complementary spline member (50) for frictionally engaging a flexible sheet (56), such as window screen, between a surface of the spline member (50) and an adjacent inner surface of one flange of the U-shaped channel (34). The structure has several practical applications including the assembly of window screen frames, electrostatic air filters of the charged media type, frames for storm windows of plastic film, and the like. An improved construction for an electrostatic air filter of the charged media type, which air filter is assembled using the construction for supporting a flexible sheet (56), is also disclosed.
(FR) Structure de support pour panneau flexible (56) comprenant un profilé en U (34) doté de semelles opposées (40, 42) conçues pour recevoir un élément complémentaire cannelé (50) de manière à serrer par frottement un panneau souple (56), tel qu'un treillis, entre une surface de l'élément cannelé (50) et la surface interne adjacente de l'une des semelles du profilé en U (34). Ladite structure a de nombreuses applications pratiques parmi lesquelles l'assemblage de châssis de fenêtre treillissées, de filtres à air électrostatiques de type à milieu chargé, de châssis de contre-fenêtre à film plastique, etc. On décrit également une structure améliorée pour un filtre à air électrostatique de type à milieu chargé, que l'on assemble en utilisant ladite structure à titre de support d'un panneau flexible (56).
