ABSTRACT:
A modular sliding window assembly has a molded plastic frame comprising a molded plastic circumferential frame member and at least one molded plastic post segment within and unitary with the circumferential frame member. The frame defines primary and secondary apertures. A sliding pane having an inboard side and an outboard side is slidable from an open position to a closed position and the sliding pane closes the primary aperture when it moves to the closed position. The sliding pane is secured to the frame by a latch assembly which includes a latch which releasably engages a latch keeper. The latch can be fixedly attached to the sliding pane and the latch keeper made unitary with one of the frame, or, alternatively, the latch may be attached to the frame and the latch keeper may be attached to the sliding pane. Anti-theft means auxiliary to the latch keeper secure the sliding pane to the frame against inboard separation of the sliding pane from the frame. The anti-theft means has at least one anti-theft projection unitary with the frame. The projection restricts inboard motion of the sliding pane, preventing disengagement of the latch from the latch keeper and thereby denying unauthorized access through the window assembly. In certain preferred embodiments a pair of projections may be used. Each projection may optionally have an arc-shaped base segment and a laterally extending segment.
