Abstract
A key device (10) includes a generally elongate shaft portion (12), and at least one magnetic key combination element (20) disposed in the shaft portion (12), which is rotatable about a rotation axis (22).
Claims11
A key device comprising:
- a generally elongate shaft portion;
- and
- at least one magnetic key combination element disposed in said elongate shaft portion and rotatable with respect to said elongate shaft portion about a rotation axis, wherein said at least one magnetic key combination element has an operative mode in which it rotates with respect to said elongate shaft portion and aligns with a magnetic plug element such that said at least one magnetic key combination element magnetically interacts with said magnetic plug element and brings said magnetic plug element to a shear line of a cylinder lock and wherein said rotation axis is not parallel to said elongate shaft portion.
A lock and key combination comprising:
- a key device comprising a generally elongate shaft portion, and at least one magnetic key combination element disposed in said elongate shaft portion and rotatable with respect to said elongate shaft portion about a rotation axis;
- and
- a cylinder lock comprising a cylinder lock housing in which a plug is mounted for rotation along a shear line, said plug comprising a keyway and being operatively coupled to a cam;
- wherein said plug comprises at least one magnetic plug element, and wherein after insertion of said key device into said keyway, said at least one magnetic key combination element rotates with respect to said elongate shaft portion and aligns with said at least one magnetic plug element such that said at least one magnetic key combination element magnetically interacts with said at least one magnetic plug element against a force of a biasing device and brings said at least one magnetic plug element to said shear line.
