ABSTRACT:
A window has a rectangular frame with pivotable sections movable between an opened and closed position. A level connected to a movement transmission bar is provided to pivot the sections about pegs mounted to a support in the frame. The level is of a deformable material and has a detent on a shaft thereof. The detent will engage a first or second opening in the frame to lock the sections in an opened or closed position. The lever can be bent to remove the detent from one of the openings and to slide the detent along the frame to the other opening. When the detent reaches the other opening, the lever will resume its initial configuration and the sections will again be locked in position. The frame has various grooves such that multiple frames can be interlocked together or runners or a wall can be mounted thereto. The sections are aerodynamically formed and are generally hollow except for interior longitudinal walls and a removable reinforcing insert. The windows allow easy ventilation and are of a relatively simple construction.
