<p>Fixed to the blind frame are brackets (12, 13) which serve as guides for the axially sliding rod (14) and as mountings for the pivots (17, 18). The pivots (17, 18) carry the arms (15, 16) on which the window wing (11) is mounted. A further pair of arms (24, 25) pivoted on the sliding rod (14) have studs (35) which slide in the slots (36) of the main arms (15, 16). A further two studs on the main arms (15, 16) bear against the edges of the shorter arms (24, 25) to limit the window opening. The pivots (26, 27) of the shorter arms (24, 25) may be clamped in any position on the bar (14) to compensate manufacturing tolerances and simplify assembly.</p> |
