Patent attributes
The description relates to an adjusting device for hook spindle rotating bolts, sash fastener rotating bolts, pull-turn bolts, swiveling bolts and the like of closures, particularly of closures for mounting in thin walls, such as sheet-metal cabinets with a frame and door, in which the closures have a closure driveshaft which is provided with an external thread and which holds a bolt so as to be axially adjustable, and/or a bolt which is provided with an internal thread or bore hole near its free end and which holds a back-engaging device so as to be adjustable perpendicular to the back-engagement plane. According to the invention, the rotating bolt carries or forms an internal thread for screwing in the closure driveshaft and one side of a coupling, such as a claw coupling, which acts by positive engagement, whose other side is held by the closure driveshaft so as to be rigid against rotation.
