Auf mindestens einen Umwelteinfluss ansprechende Stelleinrichtung für den aufklappbar gelagerten Deckel einer Dachluke, insbesondere für eine Lichtkuppel

摘要

The adjuster responds to air humidity, rain, light etc.. It has an electric motor (11) for moving reciprocally a lifting bar (7) w.r.t. to a common housing (4). The motor is controlled by a circuit (12), and can be cut-out by a limit switch. An ambient parameter sensro provides signals for the control circuit. The motor, the control and sensor circuits (12,16), and the limit switch form an integrated module in the housing. A part (10) of the sensro, affected by the ambient conditions, is integrated with the housing exterior, while the other sensor part is integrated inside the housing. The limit switch (15) responds to retarding of the lifting bar, forming a switch actuated by a preset, a theshold exceeding retardation.
