| (54) | Mechanism for closing and opening a swinging-sliding door leaf |
| (57) The invention relates to a mechanism for closing and opening a swinging-sliding door
leaf (1), comprising a fixed horizontal guide (4), over which a carriage (5) slides,
and a groove-cam (6) which is almost entirely rectilinear, except in at least one
of its ends in which it forms a curvilinear portion (6a) towards one of the sides
of the door and over which a wheel (9) supported in the door leaf slides, the mechanism
comprising a push-pull connecting rod (10), fixed in articulated manner to the carriage
(5) and to the door leaf (1), the first point of articulation (11) with the door leaf
of which remains during the closing of the door in front of the imaginary line (100)
transverse to the guide (4) passing through its second point of articulation (12)
with the carriage (5); whereas when the carriage (5) reaches the end of its path,
due to the effect of the curvilinear portion (6a) of the groove, the connecting rod
is forced to rotate until its first point of articulation (11) is located behind the
mentioned imaginary line (100).
