<p>A connection structure between three profiles (1,3,4) being at an angle to one another and being interconnected with the aid of a coupling piece (2) having parts located in two profiles (3,4) and being fastened to the third profile (1) with the aid of a bolt or the like, the position of which is such that the centre line of the bolt coincides at least substantially with the bisector of the angle between the profiles (3, 4) receiving the parts of the coupling piece (2), whereby the coupling piece (2) and the two profiles (3,4) receiving the parts of the coupling piece have co-operating elements (10,21) being at an angle other than 90 DEG to the longitudinal axes of the profiles (3,4) concerned.</p> |
