Pivot wing arrangement with electro-mechanical drive e.g. for doors

摘要

The arrangement includes an electro-mechanic drive motor with an output shaft (7) proceeding parallel to the pivot axis (11), by which a transmission lever (9) is reciprocally moved to open and close the pivot wing (1). A connecting arrangement for a slider (19) is provided at the free end of the transmission lever, which is moved along a rail (17) firmly mounted at the pivot wing during the rotation movement of the output shaft. The pivot wing is formed as a pendulum pivot, and a soluble clutch arrangement (27) is provided between the output shaft of the drive unit (6) and the slider. At an excess of an activation force opposing the opening direction, the clutch arrangement is brought into a release condition, discontinuing the connection to the drive unit. In its usual operation, the clamping and/or holding forces of the clutch arrangement in its closed position are larger than the power exercised by the drive unit.
