<p>Hinge fitting (13, 14) are used on a window or door between a frame capping (68) and a wing capping (12) parallel to it; of which the frame bearing bracket (18, 38) of the hinge fitting (13, 14) has a flat base plate (21, 41) which lies flush in a cavity (23) sunk into the visible face (22) of the frame (11) and opening out onto the frame rebate-peripheral face (24). The shallow cavity (23), on its boundary edges facing away from the frame rebate-peripheral face (24), has a contour formed by several (at least two) mutually intersecting circular arcs (67) to which the boundary edges (26) of the base plate (21) have a complementary line.</p> |
