Combination magnetic key

Claim 1

An adjustable combination key for use with magnetic locks of the general type having magnetically attractable tumbler devices and a contoured surface of a given configuration for positionally locating the key relative to said tumbler devices, which key comprises: a key body portion formed of a non-magnetic material and having front and rear surfaces connected by a side surface, said front, rear and side surfaces being shaped to define a body portion configuration corresponding to said given configuration whereby to permit said rear surface to be positionally located by said contoured surface, said body portion having a plurality of internal cavities and access openings extending between said cavities and one of said surfaces; a plurality of combination setting dials formed of a non-magnetic material, each of said dials being supported within one of said cavities for rotation through a plurality of combination setting positions about an axis extending essentially normal to said rear surface, each of said dials bearing indicia indicative of said combination setting positions thereof, said access openings affording access to said dials for permitting manual rotation thereof by an operator of said key; a plurality of magnet devices imbedded one within each of said dials in a radially spaced relationship relative to said axis of its associated dial whereby each of said magnet devices is caused to move about a circular path, as its associated dial is rotated through said combination setting positions thereof; and means for releasably retaining each of said dials in successive ones of said combination setting positions thereof.
