(57) The locking device for blinds and the like comprises a fixed stop (1,4,5) secured
to an upright (2) of a door or window to be closed by the blind and a movable part
(8) in the manner of a catch, mounted on one of the slats (3a) of the said blind and
adapted to assume a protruding position (Fig. 3) in which it may be blocked by the
stop (5) when the blind is pry opened from its lower side, and a withdrawn position
(Fig. 5) in which it can surmount the stop (5) when the blind is raised by rolling
it up, the catch-like movable part (8) having its gravity center point offset towards
a side and upwards of the plane where the articulation axis (7) thereof is located,
such that the said movable part (8) tends to assume a blocking, protruding position
under the action of gravity.
