The present invention relates to a window, comprising a case ( 2 ) and a frame ( 4 ), swingably fastened in the case by a swinging arm assembly ( 3 ). The assembly has a base plate ( 5 ), fastened to a case side piece, one end of an upper swinging arm ( 6 ) being flexibly fastened at the top of the base plate and one end of a lower swinging arm ( 7 ) being fastened at the bottom of the base in a similar way. The other ends of the arms are flexibly fastened to the top of a frame plate ( 8 ), the lower end of which supports a swinging axle ( 9 ), to be inserted into the respective side piece of the frame. Releasable locking elements are mounted between the frame and the case as well as the assembly parts, which belong thereto, respectively for a swinging limitation of the frame in relation to the case, which limitation can be cancelled. According to the invention the blocking elements are mounted adjacent the swinging center of the frame, partly at the frame plate ( 8 ) and partly at the base plate ( 5 ). At least one of the stop mechanism parts can be drawn out and be inserted respectively in a telescopic way. |
