<p>The two arms (5 and 6) of the locking means (4) are swingable relative to one another about axis (7) at right angle to the hinge axis between the leaf (2) and the frame (1). Arm (6) is swinging about hinge pin (22) arranged on a part (18). Axis (16), which is parallel to said hinge axis, connects part (18) to part (17) fastened to the leaf (2). Arm (5) is swinging about a hinge pin (11) through which said arm (5) is connected to part (9) mounted on the frame (1). In swung-shut position, the axes of hinge pins (11 and 22) coincide and are parallel to axis (7). After the arms (5 and 6) have been swung shut, the swinging movement may be continued about the coinciding axes. During this continuation, a screw (23) screwed through arm (6) cooperates with an eccentrically-running head arranged on hinge pen (11) in such a way that leaf (2) is clamped thereby against frame (1).</p> |
