Metalwork of a window and elements thereof

A metalwork for a window comprising:

• a fixed frame (2) and a leaf (3,) and a control (15) of the metalwork arranged to open and close the leaf (3) to turn round a vertical axis (X-X′) or which can tilt round a horizontal axis (Y-Y′) depending on the position of the control (15) arranged to move from a closing position in which the window (1) is closed, to a first opening position for one of either movements of the leaf (3) including turning for a turn tilt type of window (1) and tilting for a tilt before turn type of window (1), and further on into a second opening position for the other movement including tilting for a turn tilt type of window (1) or turning for a tilt before turn type of window (1);
• wherein a scissor mechanism (29) is provided with a main arm (30) freely rotatable in relation to the leaf (3) in order to tilt the window (1) and lockable in relation to the leaf (3) in order to turn the window (1) by a locking device having two coupling elements, a first coupling element (37) located on the main arm (30) and a second coupling element (38) located on the leaf (3) respectively, which can mesh to lock the main arm (30) by controlling the metalwork (1) or be moved apart in view of the free movement of the main arm (30);
• wherein at least one of the first and second coupling elements (37-38) are an adjustable part permitting via mutual adjustment, to transform the scissor part of the metalwork (1) from a turn tilt type into a tilt turn type;
• wherein the second coupling element (38) is provided on the leaf (3) on a slide lath (28) shiftable over an outer perimeter (8) by the control (15), the first coupling element (37) on the main arm (30) formed as a rotating arm (39) having an eccentric gudgeon working in conjunction with a the second coupling element (38) the rotating arm (39) provided on the main arm (30) arranged to turn half a turn between two lockable positions, corresponding to a turn tilt or a tilt before turn type of metalwork (6), respectively.
