Abstract (en)
A concealed hinge is proposed (10) for mounting a door or a sash to a frame, with a defined opening angle 0° < ω < 180° between the open (20) and closed position (40), the hinge comprising a frame part (100) with a rotation axis R (120), a sash part (200) being pivotable around said rotation axis R, a rebate section (400) including neighboring portions of the frame part (100) and the sash part (200), forming a shadow gap (405) in between when the hinge (10) is in closed state. A rotational lever-arm (300) connecting the frame part (100) and the sash part (200) exhibits, viewed in cross-section, a hook-shaped contour. The rotational lever-arm (300) encompasses an enclosed clearance area F (350), said clearance area F (350) exhibiting an essentially circle-segment shape, which is defined by four corner points A, E, I', O' with circular arcs between A and E as well as I' and O' and straight lines between A and O' as well as E and I'; said corner points A E I' O' being designated by vectors A̅, E̅, I̅' , O', between the rotation axis R and said points, thus defining a polar coordinate system with the rotation axis R representing its origin. The clearance are is geometrically defined, wherein the length of vectors A̅ and E̅ as well as I̅' and O' are pairwise equal, the angle difference between I̅' and O̅' being designated as β, the angle difference between A̅ and E̅ being designated as α and the following relations for the angles α, β, ω are being valid: α ≥ ω as well as β ≥ ω. Further, a respective method for construing such a concealed hinge is disclosed.
