A closing device for fixing an object to a manned element and a supporting device for fixing an object to a manned element

摘要

A closure device for fastening an object, for example an electronic instrument, to a carrier element includes a first closure part and a magnet device which acts in a magnetically attracting manner between the first closure part and the second closure part. At least one thread is arranged on one of the connection portions and at least one engagement element is arranged on the other of the connection portions. The connection portions are screw-connectable together by rotation with respect to one another as a result of the at least one engagement element running onto the at least one thread. The first closure part includes at least one first anti-rotation portion and the second closure part includes at least one second anti-rotation portion. The at least one first anti-rotation portion and the at least one second anti-rotation portion (33) are non-rotatably connected together when the connection portions are screw-connected, and at least one of the connection portions of one closure part is rotatable relative to the anti-rotation portion of the closure part.
