Abstract: A movable louver window has a frame body and a plurality of double-vane assemblies each having first and second louver vanes and a pair of left and right coupling members. Each pair of left and right coupling members couples said first and second louver vanes. A plurality of double-vane assemblies are mounted within the frame body. Air-tight and water-tight sealing between the frame body and the double-vane assemblies is established by seal members which are provided over the entire circumference of the frame body and continuously connected with each other.

Abstract: A sash supporting structure of a hinged swinging window includes a sash bar hinge secured to a horizontal rail of a sash and having a pivot shaft, and a support groove formed in a horizontal frame member of a window frame and pivotally receiving therein the pivot shaft of the sash bar hinge. The support groove has a width dimensioned such that the sash bar hinge can be inserted in the support groove from the inner periphery side of the window frame. With this arrangement, the sash can be readily installed in the window frame without requiring prior connection between the horizontal rail or the sash and the horizontal frame member. The sash supporting structure further has a dislocation stop member secured to the horizontal frame member of the window frame and extending through a cutout opening in the sash bar hinge to prevent horizontal in-plane displacement of the sash bar hinge.

Abstract: A panel fastener construction is used for fastening a plurality of building panels to a primary structure with a uniform gap interposed between each vertically adjacent panels. The panel fastener construction comprises a plurality pair of upper and lower upward supporting hooks provided on the primary structure with the upper and lower upward supporting hooks vertically spaced from each other, and a pair of upper and lower downward catching hooks provided on the exterior side of each panel for engagement with the upper and lower upward supporting hooks, respectively, of the primary structure. The height of the downward hooks is slightly less than the inter-panel gap.

Abstract: A door pull comprises a pull member and a pair of fittings coupled with opposite ends of the pull member. The door pull is attached to a door by these fittings.

Abstract: A weatherproof curtain wall unit (U) comprises a rectangular frame (F) enclosing a panel (P) therein and a resilient weatherstrip (A) provided at least along a pair of vertical sides and an upper side of the rectangular frame (F). The resilient weatherstrip (A) is offset between the vertical sides and the upper side to prevent a gap from arising between the resilient weatherstrips (A, A) of the adjacent curtain wall units (U1, U2, U3).

Abstract: In a windowsill, when a sill attachment is pushed downwardly by the weight of a window pane, a pair of vertical plates of a sill member are pulled inwardly by engagement of downward hooks of a horizontal plate with upward hooks of vertical plates, thereby keeping the vertical plates from being deformed outwardly. Therefore, no gap would be formed between the vertical plates and side muntins, keeping rain water from penetrating into the windowsill.
