Abstract
A device for sequentially switching at least one first and at least one second Venetian blind, the slats of which can each be synchronously rotationally moved by means of at least one coupling rod in order to open and close the blinds. The device includes an actuator for generating a rotational movement of the slats through 80° to 90°, a coupling for rotatably coupling the actuator to a slat of the first blind, a link rod which has a partially-circular link, and a transmission rod. The actuator has an eccentric pin parallel to its axis of rotation which engages in the partially-circular link of the link rod, and the linear movement of the link rod is transmitted to the coupling rod of the at least second blind.

1-11. (canceled)
An apparatus for the sequential switching of at least one first louvre blind (11) and at least one second louvre blind (12, 13), the slats (2) of which are synchronously rotationally moveable by means of at least one respective coupling rod (6) to open and close the louvre blinds including
- an actuator (10) for producing a rotary movement of the slats through 80° to 90°,
- a coupling for rotatably coupling the actuator to a slat of the first louvre blind (11),
- a link rod (9) having a part-circular sliding guide (92), and
- a transmission rod (8),
- wherein the actuator has an eccentric pin (102) which is parallel to its axis of rotation (101) and which engages into the part-circular sliding guide of the link rod,
- wherein
- there is provided a stationarily rotatably mounted transmission rod (8) which has pivotal levers (82 and 83) fixed thereto, wherein the link rod (9) acts on the pivotal lever (83) for rotation of the transmission rod and the pivotal lever (82) acts on the coupling rod (6) of the at least second louvre blind so that the linear movement of the link rod (9) can be transmitted by way of the transmission rod to the coupling rod (6) of the at least second louvre blind (12, 13).
An apparatus for the sequential switching of at least one first louvre blind (11) and at least one second louvre blind (12, 13), wherein the slats (2) of a louvre blind are synchronously rotationally moveable by means of at least one respective coupling rod (6) associated therewith to open and close the louvre blinds including
- an actuator (10) for producing a rotary movement of the slats through 80° to 90°,
- wherein the actuator has two eccentric pins (102, 103) which are parallel to its axis of rotation (101) and non-rotatably connected thereto,
- a link rod (9) having a part-circular sliding guide (92),
- wherein one of the pins (102) engages into the part-circular sliding guide (92) of the link rod (9),
- wherein the coupling rod (7) of the first louvre blind (11) has a part-circular sliding guide (92) which is complementary to the sliding guide of the link rod and into which the second pin (103) of the actuator engages whereby the coupling rod (7) can be displaced in a guided linear movement,
- and a linear movement of the link rod can be transmitted to the coupling rod of the second louvre blind (12),
- wherein
- the pins (102) and (103) are peripherally displaced through 70° to 110° relative to the axis of rotation (101).
