Abstract: The present invention relates to an arrangement in a pivotal screen or screen section for substantially continuous adjustability and parking of the screen in the desired position, the screen or screen section being provided with an upper hinge and a lower hinge, and the lower hinge being provided with a conicity for achieving a braking effect against pivoting of the parts in relation to one another.

Abstract: The present invention relates to a structural element for realizing continuous surfaces, for example a screen, a partition wall, a hoarding or the like, essentially for screening-off from noise, view, etc., each corner (5, 6, 7, 8) of a substantially quadrilateral, hollow profile (1-8) being reversed and directed in towards the center of the profile (1-8), and at least one side (1) of the profile (1-8) indented because of corner reversal, being provided, at each edge, with an outwardly directed flange (9, 10), the flanges (9, 10) being parallel with one another and fitting over the sides, indented because of corner reversal, of another substantially identical profile (1-8).
