Roof window frame and method for embedding the window frame in a roof

Abstract

The subject of the invention is a roof window frame with two opposite parts ( 1 ) determining the window height, having in their outer side wall on their full length a rectangular recess ( 2 ) with a supporting surface ( 2 a ) facing the roof, and having through fixing holes ( 3 ) between the frame surface above the glazing plane and the parallel supporting surface ( 2 a ) of the recess ( 2 ). The method of embedding and fixing the window frame in the roof following the invention includes inserting the window frame in an opening of matching size in the roof surface so that the supporting surface ( 2 a ) of the recess ( 2 ) in the side parts ( 1 ) rests on the rafter framing elements of the roof, and then screwing it down to these elements with screws inserted in the through holes ( 3 ) in the side parts ( 1 ).

What is claimed is:  
     
         1 . A roof window frame characterized in that its two opposite side parts ( 1 ) determining the window height, have in the outer edge, on their full length at the side facing the roof, a rectangular recess ( 2 ) with a supporting surface ( 2   a ) and fixing holes ( 3 ) running from the window frame surface above the glazing plane to its parallel supporting surface ( 2   a ).  
     
     
         2 . A roof window frame as claimed in  claim 1  in which the through fixing holes ( 3 ) in the side parts ( 1 ) are arranged in diverging directions with respect to each other towards the roof surface.  
     
     
         3 . A method for embedding a window frame in a roof characterized in that the window frame is being inserted into an opening of matching size in the roof surface so, that the supporting surface ( 2   a ) of the rectangular recess ( 2 ) in the opposite side parts ( 1 ) determining the window height rest on the rafter framing elements of the roof and is then being screwed to it by screws inserted in the through holes ( 3 ).
