- the lever 7, integral with the pivot axis 8 of the louver blade 1 is provided with several holes 22 intended to cooperate with a lug secured to the corresponding end of the connecting rod 21, these holes 22 extending radially from the pivot axis 8 of the louver blade 1 and offset from a straight line connecting the pivot axis 8 to the drive pin 20 of the lever 7.
- each lever 7 is pivotally driven around the axis 8 of the louver 1 and the traction exerted by the spring forming the elastic prestressing means 11 on the link 21 and on the lever 7 achieves a lifting torque of the corresponding louver blade, the actuation of the means 2 simply requiring the development of a force corresponding to the friction forces in the different mechanisms.
- the force necessary for the operation of the means 2 is identical, the torque developed by the spring then serving only to maintain the louver blade and avoiding any sudden movement due to the weight of the latter.
- the elastic prestressing means 11 provides the same effect.
- the means 2 for centralized control of the louver blades 1 is advantageously constituted by a sliding handle 23 guided in the housing 4 and acting on the control lever 17 cooperating with the actuation means 3 louvre blades 1 by means of a cam 24 cooperating with at least one roller 25 of a pivot plate 26 articulated on said lever 17 ( Figure 1).
- a vertical displacement of the handle 23 will cause a corresponding displacement of the pivot plate 26 and of the lever 17 along the curve of the cam 24, so that device 10 for compensating the weight of the blades constituting the louvers 1 will be actuated and that the rod 6 will be moved in the corresponding direction.
- a straight profile of the cam 24 at the end of travel ensures the locking of the blades forming the blinds 1 in the closed and open positions.
- FIG. 3 of the accompanying drawings shows another alternative embodiment of the invention, in which the means 2 for centralized control of the louver blades 1 is in the form of a rotating handle 27, guided on the housing 4 and cooperating with an axis maneuver 28 via a screw and nut connection, this operating axis 28 being connected to articulation with the lever 17 by means of a drive pin 29, the lever 17 being connected to its articulation in the housing 4 by a guide slot 3 '.
- the operation of the rotary handle 27 causes a linear displacement of the operating axis 28 and a corresponding pivoting of the lever 17, simultaneously with the actuation of the device 10 for compensating the weight of the blades constituting the louvers 1.
- FIGS. 5 and 6 show the application of the sliding 23 and rotating 27 handles to the embodiments of the device concerning the application to decentralized compensation.
