Window and frame with transom - has transom window suspended by linkage from frame members and forming stop for hinging leaves

摘要

The fixed frame (2) encloses a single opening shut by the leaves (7) and transom window (12). The frame (16) of the latter is suspended by a linkage (18) from the lengthwise members (3, 4) of the fixed frame, while its bottom cross-member (14) forms a stop for the cross-members (8) of the leaf frames (17). The transom and leaf cross-members can lie flat against each other over at least part of their surfaces. ADVANTAGE - Gives impression, despite double-glazing, or single-glazing, eg in an old building.
