A pivot bracket for supporting an outwardly-opening window casement

A pivot bracket for use in support of an outwardly opening window comprises an elongate mounting member (10), for securement to the inside of a window frame, an elongate support member (11) for attachment to an edge of a window, and two arms (12, 13) pivoted at opposite ends to the two members. The members (10) (11) having means (24) (25) for holding them in the closed position. The axes of the pivot connections (16, 18) to the mounting member (10) are further apart than the axes of the pivot connections (20, 22) to the support member (11) to provide a swinging movement to the window during opening whereby both sides of the window can be cleaned from inside the window frame. The geometry is such as to provide a self-locking action when the window is closed.
