A key device () includes a generally elongate shaft portion (), and at least one magnetic key combination element () disposed in the shaft portion (), which is rotatable about a rotation axis ().

Rotatable magnetic key combination element

A key device includes a generally elongate shaft portion that has first and second oppositely directed side surfaces, at least one of which is cuttable to form key cuts that define a key combination surface. First and second key combination elements, disposed in the elongate shaft portion, are side-by-side one another at different lateral positions along the width of the elongate shaft portion and located at overlapping longitudinal positions along the length of the elongate shaft portion. The first and second key combination elements are each pivotable about a pivot axis.

Key combination element in key blank and key

A key device () includes a generally elongate shaft portion () including a key combination surface () that has a plurality of key cut stations () for forming telescoping key cuts at each key cut station (). Each key cut station () has a telescoping maximum adjacent cut specification (MACS) that defines a maximum depth of adjacent. The key device () also has a non-MACS key cut (), formed at one or more of the key cut stations (), for interfacing with a first pin () of a given telescoping plug pin. The non-MACS key cut () is dimensioned to leave material in the elongate shaft portion () for forming another key cut (A) for interfacing with a second pin () of the given telescoping plug pin.

Eliminating maximum adjacent cut specification restrictions for telescoping pins

A lock assembly () including a plug () having a keyway () for inserting therein a key (), the plug () arranged for movement in a bore () formed in a lock body () along a shear line () defined between an outer perimeter of the plug () and an inner perimeter of the bore (), and at least one movable element () slidingly disposed in an opening formed in the plug (), wherein insertion of the key in the keyway () without movement of the plug () in the lock body () does not align the at least one movable element () with the shear line (), but movement of the plug () in the lock body () with the key () inserted in the keyway () aligns the at least one movable element () with the shear line ().

Lock assembly with movable element

A lock assembly () including a plug () having a keyway () for inserting therein a key (), and a movable element () movingly disposed in the plug (), the movable element () being divided into at least two separate magnetic portions () arranged to move relative to one another and having identical magnetic polarity, wherein the magnetic portions () are sufficiently near one another such that one of the magnetic portions () applies a magnetic repelling force on the other magnetic portion ().

Magnetically repelling lock assembly

A lock and key combination that uses a key device which includes a shaft portion, and at least one movable key combination element which is retained within the shaft portion and which includes first and second portions adjacent one another, the first portion of the at least one movable key combination element being located along on the shaft portion and the second portion of the at least one movable key combination element being located offset to the first portion.

Movable key combination element and lock assembly

A key device for use with more than one lock, the key device including a shaft portion, and at least one movable key combination element retained within the shaft portion and including first and second portions adjacent one another, the first portion of the at least one movable key combination element being located along on the shaft portion and the second portion of the at least one movable key combination element being located offset to the first portion.

A key blank including a generally elongate shaft portion defining first and second generally flat oppositely directed side surfaces, joined by edge surfaces, at least one of the first and second side surfaces cuttable to form key cuts that define a key combination surface, and at least one key combination element movably disposed in the elongate shaft portion and adapted for touching a lock combination element disposed in a cylinder lock plug, wherein the at least one key combination element has inherent energy for applying an urging force against the lock combination element. A key formed from the key blank and lock therefore are also disclosed.
