<p>A length-adjustable extension rod, near the too wing edge, incorporates a holder with a threaded hole. There is a screw engaging the rear flank of an end sideways-facing lug shaped as a hook protruding into a widened part of a shaft-shaped opening in a fitting for esp. turning and tilting wings on windows or doors . The leaf spring (40), acting as brake guide and running lengthways in this shaft (17), has a flap (45) bent back sideways towards the adjusting screw (20), in contact with the screw's thread lines.</p> |
