t is disclosed herein a mechanism applicable to a tilting casement, which mechanism comprises one or several separately detachable parts, the detachment and consequent reinstallation of which can be quickly achieved in such a way that the stabilityof the whole mechanism is not affected, the connected-to-the-handle central stem 3 is not detached, and the potential intervention to a selected part of the mechanism is substantially facilitated. More precisely, there is proposed the addition & removal of the angular element 1 which is connected to the arm-scissor 5 of the roof of the casement and/or the lower vertically positioned latch 2. Through the end hole of the angular element 1 and latch 2, the coupling element 9 passes to connect them with the rest of the mechanism; consequently, the angular element 1 and the latch 2 can be separately detached, upon decoupling of the coupling element 9. |
