Abstract
The disclosure relates to opening window, door or the like comprising a frame (1, 2), a casement (3, 4) and an exteriorly disposed protective cladding (7). The invention is designed to offer such a simple solution to the suspension of the casement and the mounting of the protective cladding as also permits that the casement may be pivoted so that its outside will be interiorly accessible. The window has at least one portion of the protective cladding (7) designed as a retainer unit which is pivotal and is fixedly retained in the frame (1, 2) by means of hinges (9). The casement (3, 4) is connected to the retaining unit by means of second hinges (10). The window is further provided with releasable locking devices (11) on the casement and the retaining unit, or grooves (13, 14) in the frame and a corresponding pin on the casement so as to hold together the casement and retaining unit whereby these, on normal opening and closing, are pivotal together as one unit while the casement, in certain positions, may be swung out away from the retaining unit and turned with its outside facing inwardly.
