DESCRIPTION:
BRIEF SUMMARY
On the basis of the technical teaching derivable from DE-GM 8707653, the invention relates to a window for installation in an inclined roof with a main frame in which an upper window frame and a bottom-hinged lower frame are journalled, which frames in their closed position are situated in extension of each other in the height direction of the main frame and together cover the main frame opening, whereas the lower window frame by opening may be turned outwards into a substantially vertical position to form the breast wall of a balcony.
Said publication discloses an embodiment having a bottom-hinged lower frame in connection with a displaceable upper frame.
When the main frame is installed with its bottom member at a suitably low height above the floor in a top storey of a building, part of the closet space situated at the roof foot may be used as a balcony or roof terrace when the two window frames are opened, the lower frame forming a breast wall and the upper frame which may be top-hinged constituting a shed roof thereover, whereas the balcony is sidewards limited by side railings connected between either side of the lower window frame and the associated main frame side member and being unfolded and folded up upon opening and closing the lower window frame.
The object of the invention is to provide a window arrangement which in a relatively simple manner may be adapted to installation in inclined roof surfaces with varying inclinations within a predetermined angular range, e.g. 35.degree.-55.degree..
Based on the recognition of the fact that in order to meet aesthetic demands it is important that the handrails of the side railings with the lower window frame opened to a vertical position are substantially horizontal and the vertical bars of the side railings substantially vertical, the window according to the invention is characterized in that handrails connected between the lower window frame and each of the side portions of the main frame, and each forming in the open balcony position of the window the upper edge of a side railing, each have a length suitable for installation of the window at the smallest roof inclination within a specified angular range and is designed to be cut off for adaptation of its length to the actual roof inclination after having been permanently connected to the lower window frame and the relevant side portion of the main frame in its almost horizontal position, and vertical rail bars of each side railing being connected to the associated horizontal rail by means of pivotal joints, which are longitudinally displaceable in relation to the horizontal rail and can be fastened in arbitrary positions along same.
With this design of the handrail of each side railing and the joints for the vertical rail bars designed for connection therewith, it is obtained that during installation with the lower window frame being placed in its vertical position and the handrail in its horizontal position and after connection of the handrail to the side portion of the main frame and the lower window frame, respectively, a possible necessary adjustment of the length of the handrail can be made by cutting off the end of it projecting beyond the lower window frame. The vertical rail bars can then be placed in vertical positions evenly spaced, and their upper pivotal joints fastened to the handrail.
A simple embodiment which is easy to install can be obtained by shaping the horizontal rail as a U-profile with inwards turned edge portions at its downwards facing aperture for guiding said pivotal joints for the vertical rail bars, said pivotal joints being shaped as a U-profile adapted to fit into the handrail with a fastening screw for securing the pivotal joint against displacement in relation to the handrail, one of two pivotally connected parts of a fitting connected to the lower window frame being likewise shaped as a U-profile adapted to matchingly surround the handrail.
In order to facilitate fastening of the horizontal rail to the lower window frame prior to length adjustment said one part of the
