    Abstract: The present invention relates to a chain actuator (1) for a window unit. Said window unit (2) comprises a fixed part (21) and a movable part (22) which are connected together and mutually movable.
    The chain actuator (1) comprises a frame (30) having a fixed portion (31) and a movable portion (32) apt to be coupled to the fixed part (21) and to the movable part (22), respectively.
    The actuator (1) also comprises an articulated chain (40) connected to the fixed portion (31) and to the movable portion (32) so as to move the movable portion with respect to the fixed portion in order to operate the window unit (2). The articulated chain (40) is composed of a plurality of segments (41) arranged in series between a head segment (42), connected to the movable portion (32), and a tail segment. Each segment has a direction of extension (S) and is connected to at least one further segment in such a way as to rotate reversibly about a hinge axis (C) in a first jamming direction (α11) or a first winding direction (α12) so as to orient its direction of extension (S), between a jamming angle and a winding angle, respectively. In the jamming angle position each segment of the plurality of segments (41) has its direction of extension (S) substantially parallel to the direction of extension (S) of the further segment so as to exert a thrust along an operating direction (D) so as to move the fixed portion (31) and the movable portion (32) of the frame (30) with respect to each other.
    The actuator (1) further comprises an actuation device (50) coupled to the fixed portion (31) and to the articulated chain (40) and able to be operated so as to extend said chain or retract it from/inside the fixed portion (31).
    In particular, the movable part (32) comprises, in turn, a fixing element (35), apt to be fixed to the movable part (22) of the window unit (20), and a coupling element (34) associated with the fixing element (35) so as to be able to rotate with respect to the latter about a first axis of rotation (A) transverse to the operating direction (D).
    The head segment (42) is connected to the coupling element (34) so as to rotate reversibly in a second jamming direction (α21) or in a second winding direction (α22) about a second axis of rotation (8), parallel to the hinge axis (C) and transverse to the first axis of rotation (A).
    The articulated chain (40) and said coupling element (34) are mutually configured and coupled together so that a rotation of the plurality of segments (41) in the first jamming direction (α11) is followed by a rotation of the head segment (42) in the second jamming direction (α21) which is limited by an interference between the head segment (42) and the coupling element (34) thus defining an angular jamming position of the head segment (42).
