Abstract
A sliding sash window ventilator assembly for insertion between the window sashes and the window frame comprises an elongate ventilator housing having an air passage through and between its inner and outer lateral faces and an elongate facing member mounted by a parallel motion linkage onto said ventilator housing, such that lengthwise movement of said facing member produces movement of said facing member towards or away from said housing between a fully closed position obstructing said air passage and a fully open position.
Claims28
A ventilator assembly for a sliding sash window comprising an elongate ventilator housing with inner and outer lateral faces, an air passage through and between its inner and outer lateral faces and an elongate facing member mounted on hinges of a parallel motion linkage onto said ventilator housing such that lengthwise movement of said facing member produces movement of said facing member towards or away from said housing between a fully closed position obstructing said air passage and a fully open position, the hinge being positioned within the air passage in the housing, a first airflow section adjacent said outer face of said housing, a third airflow section adjacent said inner face of said housing and a second airflow section linking said first and third airflow sections, said first and third airflow sections being substantially parallel to and spaced from one another and said second airflow section being substantially normal to said first and third airflow sections.
A ventilator assembly for a sliding sash window comprising an elongate ventilator housing comprising a uniform section extrusion with inner and outer lateral faces, an air passage extending through the housing perpendicular to its length between openings formed in its inner and outer lateral faces, an elongate facing member mounted on hinges of a parallel motion linkage onto said ventilator housing such that lengthwise movement of said facing member produces movement of said facing member towards or away from said housing between a fully closed position obstructing said air passage and a fully open position, the hinges being positioned within the air passage in the housing, the housing also defining an outer sash facing surface.
A ventilator assembly for a sliding sash window, comprising an elongate ventilator housing comprising a uniform section extrusion with an air passage extending through the housing perpendicular to its extruded length between openings form in its inner and outer lateral faces, an elongate facing member mounted by a parallel motion linkage onto said ventilator housing such that lengthwise movement of said facing member produces movement of said facing member towards or away from said housing between a fully closed position obstructing said air passage and fully open position, the assembly further being provided at its outer lateral face with an angular longitudinally extending channel for location of an elongate exterior hood, which angular channel comprises a first substantially horizontal section and a second substantially vertical section extending from the base of said first section.
A sash window comprising a window frame, inner lower and outer upper sashes mounted to slide respectively within inner and outer channels in said window frame, and a ventilator located between said sashes and said window frame, the said ventilator comprising an elongate ventilator housing having an air passage through and between its inner and outer lateral faces and an elongate facing member mounted by a parallel motion linkage onto said ventilator housing such that length wise movement of said facing member produces movement of said facing member towards or away from said housing between a fully closed position obstructing said air passage and a fully open position, the housing further having substantially horizontal inner and outer sash facing surfaces, said inner and outer sash facing surfaces being substantially parallel to and spaced from one another;
- the ventilator being further provided at its uter lateral face with an angular longitudinally extending channel for location of a member selected from the group consisting of an elongate exterior hood and a spacer for said elongate hood, and said air passage comprising a first air flow section adjacent said outer face of said housing, a third airflow section adjacent said inner face of said housing and a second airflow section linking said first and third airflow sections, said first and third airflow sections being substantially parallel to and spaced from one another and said second airflow section being substantially normal to said first and third airflow sections.
