Abstract:
1. A magnetic coupling device, comprising a first element and a second element, wherein the first and the second elements either are integrally connected with the objects to be coupled or are mounted on the objects, the coupling device comprising: a coupling element coupling the first element and the second element, wherein the coupling element is movable on the second element in two degrees of freedom in that a first magnetic system, which is arranged on the first element and comprises at least two magnets or a magnet arrangement with two magnetic poles; a second magnetic system, which is arranged on the coupling element and comprises two magnets or a magnet arrangement with at least four magnetic poles, of which at least two magnetic poles are arranged on the front side of the coupling element facing the first magnetic system, wherein by means of the input actuation in the second degree of freedom the coupling element is moved in the first degree of freedom from the coupling position, in which the coupling element is in attraction to the first element, into the decoupling position, in which the coupling element is in repulsion to the first element; and a third magnetic system, which is arranged on the second element and comprises at least two magnets or a magnet arrangement with two magnetic poles, wherein in the second magnetic system of the coupling element at least two magnetic poles are arranged on the rear side facing the third magnetic system, wherein by means of the input actuation in the second degree of freedom the coupling element is moved in the first degree of freedom from the coupling position, in which the coupling element is in repulsion to the second element, into the decoupling position, in which the coupling element is in attraction to the second element.
