Closure Device for Fastening an Object to a Carrier Element and Fastener for Fastening an Object to a Carrier 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.

主权项

1. A closure device for fastening an object to a carrier element, said closure device having
a first closure part which comprises a first connection portion, a second closure part which comprises a second connection portion and is mountable onto the first closure part in a closing direction and a magnet device which, when the closure parts are placed together, acts in a magnetically attracting manner between the first closure part and the second closure part, wherein 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, and the connection portions are screw-connectable together by rotation with respect to one another around the closing direction as a result of the at least one engagement element running onto the at least one thread, wherein 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, wherein the at least one first anti-rotation portion and the at least one second anti-rotation portion 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 said closure part.
