Abstract

A louvre window having: a frame, the frame having a head, a sill and at least two jambs; a drive bar located in one or both of the jambs that is movable by a handle; a plurality of blades located within the frame and connected to the drive bar by a pivot drive connector, such that movement of the drive bar urges the blades to pivot, each blade having: a first windowpane attached to the blade; and a second windowpane attached to the blade, wherein operation of the handle causes movement of the blades between an open position and a closed position, wherein in the open position the first windowpanes are aligned to form a barrier against airflow and the second windowpanes are aligned to form a barrier against airflow and in the closed position the first windowpanes are pivoted out of alignment to allow airflow and the second windowpanes are pivoted out of alignment to allow airflow.

Dependent claims

A louvre window having:

a frame, the frame having a head, a sill and at least two jambs;
a drive bar located in one or both of the jambs that is movable by a handle;
a plurality of blades located within the frame and connected to the drive bar by a pivot drive connector, such that movement of the drive bar urges the blades to pivot, each blade having:
a first windowpane attached to the blade;
and
a second windowpane attached to the blade,
wherein operation of the handle causes movement of the blades between an open position and a closed position, wherein in the closed position the first windowpanes are aligned to form a barrier against airflow and the second windowpanes are aligned to form a barrier against airflow and in the open position the first windowpanes are pivoted out of alignment to allow airflow and the second windowpanes are pivoted out of alignment to allow airflow;
wherein the drive bar includes a pair of link bars and the pivot drive connector is connected to a respective link bar at opposite sides of the pivot drive connector such that differential translation of the link bars causes pivoting of the pivot drive connector;
and
wherein the link bars each have an upper and a lower recess for each pivot drive connector at an interior edge thereof, and the pivot drive connector has a boss that conforms to each recess, such that when the link bars are differentially translated, the boss releasably snaps into the upper recess of one link bar and the lower recess of the other link bar.

A louvre window having:

a frame, the frame having a head, a sill and at least two jambs;
a drive bar located in one or both of the jambs that is movable by a handle;
a plurality of blades located within the frame and connected to the drive bar by a pivot drive connector, such that movement of the drive bar urges the blades to pivot, each blade having:
a first windowpane attached to the blade;
and
a second windowpane attached to the blade,
wherein operation of the handle causes movement of the blades between an open position and a closed position, wherein in the closed position the first windowpanes are aligned to form a barrier against airflow and the second windowpanes are aligned to form a barrier against airflow and in the open position the first windowpanes are pivoted out of alignment to allow airflow and the second windowpanes are pivoted out of alignment to allow airflow,
wherein each blade further includes
a slide drive member that pivots together with the pivot drive connector, the slide drive member having a recess that pivots with the slide drive member, and
a sliding member mounted to be movable in a first direction parallel to the first windowpane and having a lower end that extends in a second direction normal to the first windowpane as well as a drive boss received by the recess in the slide drive member,
wherein, when the blades are driven from the closed position to the open position, the slide drive member pivots and thereby urges the sliding member in the first direction to increase a distance between the first windowpane and the second windowpane.

A louvre window having:

a frame, the frame having a head, a sill and at least two jambs;
a drive bar located in one or both of the jambs that is movable by a handle;
a plurality of blades located within the frame and connected to the drive bar by a pivot drive connector, such that movement of the drive bar urges the blades to pivot, each blade having:
a first windowpane attached to the blade;
and
a second windowpane attached to the blade,
wherein operation of the handle causes movement of the blades between an open position and a closed position, wherein in the closed position the first windowpanes are aligned to form a barrier against airflow and the second windowpanes are aligned to form a barrier against airflow and in the open position the first windowpanes are pivoted out of alignment to allow airflow and the second windowpanes are pivoted out of alignment to allow airflow,
wherein each blade further includes a cap member between the first and second windowpane, and
wherein each blade further includes a sliding member mounted to be movable in a second direction and to which the first windowpane is attached, the sliding member having an upper end extending over the first windowpane, and wherein the cap member has a lower end extending below second windowpane such that, when the blades move from the closed position to the open position, the lower end of the cap member of an upper blade abuts the upper end of the sliding member of a lower blade to urge the first windowpane of the lower blade in the second direction.
