  • Key combination element in key blank and key
    Patent number: 11933071
    Abstract: 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.
    Type: Grant

  • Eliminating maximum adjacent cut specification restrictions for telescoping pins
    Patent number: 9784013
    Abstract: A key device (10) includes a generally elongate shaft portion (12) including a key combination surface (16) that has a plurality of key cut stations (18) for forming telescoping key cuts at each key cut station (18). Each key cut station (18) has a telescoping maximum adjacent cut specification (MACS) that defines a maximum depth of adjacent. The key device (10) also has a non-MACS key cut (20), formed at one or more of the key cut stations (18), for interfacing with a first pin (24) of a given telescoping plug pin. The non-MACS key cut (20) is dimensioned to leave material in the elongate shaft portion (12) for forming another key cut (20A) for interfacing with a second pin (26) of the given telescoping plug pin.
