Checking assembly, suitable for motorized opening, closing or holding of wings

摘要

The motorised scissor assembly has an elongated housing (1) with a first longitudinal extension for the scissor assembly (7) and with a motorised drive on the inside of a second longitudinal extension. An engagement unit is longitudinally displaceable on a side opposite the attachment site of the scissors through a thread-less elongated shear rail which is coupled to the motorised drive. A nut longitudinally displaceable by a spindle rod is coupled to the drive. The drive has two synchronised elongated shear members. Two scissor-free sides of the housing are set close together so that the opposing end sides do not have the same width. - Independent claim describes structural space for holding electric or electronic switch units and extends between one end of the electric drive unit with motor and gearing, and a rear side of a connecting terminal.
