  • Articulation fittings for window casings opening according to the Italian art
    Patent number: 4996794
    Abstract: Articulation fittings for window casings which partially covers the dormant casing and openings according to Italian art include lower compass arms and upper articulation members which cause the top rail of the window casing to project from the dormant casing during window opening movement. To detach immediately the top rail of the window casing from the dormant casing and thus avoid a premature wear and tear of the sealing joints adhering to the window casing, the articulation fittings are provided with means, which at the very beginning of the opening movement, cause the window casing to follow a path having a vertical component while causing the top rail of the window casing to follow a path having a horizontal component.
