Abstract

A sliding door construction in which two sliding door panels are adapted to be moved into open position or into a position where one panel is in open or partially open position and the other panel is in closed position and wherein one of the juxtaposed stile members of the door panels is provided with a movable pivoted insect barrier blade extending the length of the stile member and in operative insect barrier position lying normal to the plane of the door panels and having a width for virtually closing the space between the stile and the surface of the other door panel. In non-operative position of the barrier blade, the blade lies parallel to the plane of the door panels. The barrier blade has an actuator rib engageable by an actuator flange carried by the stile of the other door panel for pivotally moving the blade into the said normal position to the planes of the door panels and to parallel position of the door panels. A sliding door construction which additionally includes a fixed door panel and a fixed insect barrier blade carried by the stile of the sliding door panel proximate to the fixed panel. A barrier strip member for use between relatively movable sliding panels in which the strip member includes a flange section extending normal to the strip member and hinge means along a longitudinal edge of the blade member adjacent the flange section.

Claims

1. In a sliding door construction having an inside fixed door panel, a sliding outer door panel, interlock means between juxtaposed door stiles in closed position, an outside sliding screen panel opposite the outside sliding door panel, both outside panels being movable relative to each other and the fixed door panel, the interlock stile of the outer sliding panel forming a space between the interlock stile and the glass surface of the fixed panel when the outer sliding panel is fully or partially opened, and the screen panel having a screen stile forming a space with the glass surface of the outer sliding panel when the outer panel is fully or partially opened;

the provision of;

barrier means for closing said spaces between the outer sliding panel, screen panel, and fixed panel;

said barrier means comprising;

a fixed blade extending the length of said outer sliding panel interlock stile, carried thereby, and extending inwardly into close proximity with the glass surface of the fixed door panel;

a movable barrier blade carried by the screen stile and extending in operative position into proximity with the glass surface of the outer sliding panel and extending the length of the screen stile;

said movable blade in non-operative position being parallel to plane of the screen panel;

and means on the movable blade and means on the interlock stile of the outer sliding panel for actuating said movable blade into said two positions upon relative sliding movement of said sliding panels;

said means for actuating said movable blade includes;

hinge means for said movable blade carried by the screen stile;

an actuator member on said movable blade adjacent said hinge means and extending in closed position of the outer sliding panel in the direction of sliding of said sliding panel;

said means on said outer sliding panel interlock stile for actuating said movable blade including an outwardly extending projection adapted to engage said actuator member on the movable blade when the screen panel is opened to pivot said movable blade into a position parallel to the screen panel, and to return said movable blade to a position normal to the screen panel and into closed operative position.

2. In a sliding door construction including two sliding door panels having panel surfaces lying in spaced parallel planes adapted to be moved into open position or into a position where one panel is open or partially open and the other panel is closed, each of said door panels having frame members in juxtaposed position when both panels are in relatively displaced position, the provision of:

a movable closure blade extending the length of said frame members and in closed position of said sliding panels extending normal to the plane of said panel surfaces and having a width for virtually closing the space between said panels;

and means carried by one of said frame members for actuating said closure blade into and out of operative position;

said means for actuating said movable blade includes a projection on said blade;

a cooperative projection on said frame member of one of said sliding panels adapted to contact said projection on said blade to move said blade from inoperative position parallel to one of the panel surfaces to an operative position normal to said panel surfaces.

3. A sliding panel construction as stated in claim 2 wherein said blade includes:

pivot means extending along one edge thereof adjacent one of the sliding panels,

means carried by said one of said panels for biased pressure engagement against said pivot means;

and means on said one edge for normally retaining said movable blade either normal to the plane of said panel surfaces or parallel to said panel surfaces when said sliding panel surfaces are in open condition.

4. A sliding panel construction as stated in claim 2 wherein:

said movable blade pivots about a longitudinal axis; and

said projection on said blade normal thereto includes an elongated flange section spaced from said axis.

5. A sliding panel construction as stated in claim 2 wherein:

said cooperative projection on said frame member includes a longitudinally extending rib projecting from the outer surface of said frame member and adapted to be received within the included angle formed by said blade projection and blade.

6. A door construction as stated in claim 2 wherein

said movable closure blade includes pivot means;

and hinge means carried by one of said frame members and engaged with said pivot means;

said hinge means including biased pressure means in engagement with said pivot means.

7. A sliding door construction as stated in claim 6 wherein

said hinge means includes a spring for exerting pressure against said pivot means on said blade.

8. A door construction as stated in claim 7 wherein

said spring means includes a flat configured spring member having a flat loop portion for contact with said pivot means.

9. A door construction as stated in claim 7 wherein

said spring means includes a coil spring having one end exerting spring pressure forces in a direction toward said pivot means.
