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.
Claims13
A key device comprising:
- a generally elongate shaft portion having a length and a width that respectively define longitudinal and lateral positions along said elongate shaft portion, said elongate shaft portion comprising first and second oppositely directed side surfaces, at least one of which is cuttable to form key cuts that define a key combination surface;
- and
- first and second key combination elements, disposed in said elongate shaft portion, side-by-side one another at different lateral positions along the width of said elongate shaft portion and located at overlapping longitudinal positions along the length of said elongate shaft portion, wherein said first and second key combination elements are each pivotable about a pivot axis, and wherein said first and second key combination elements are independently active biasing elements, capable of providing a biasing force independently from one another.
A key device and lock assembly comprising:
- a cylinder lock housing comprising a driver pin movable to a shear line;
- a plug having a keyway and rotatable relative to said cylinder lock housing along the shear line said plug comprising a plug pin aligned with said driver pin and movable to the shear line;
- and
- a key device comprising a generally elongate shaft portion having a length and a width that respectively define longitudinal and lateral positions along said elongate shaft portion, said elongate shaft portion comprising first and second oppositely directed side surfaces, at least one of which is cuttable to form key cuts that define a key combination surface;
- and
- first and second key combination elements, disposed in said elongate shaft portion, side-by-side one another at different lateral positions along the width of said elongate shaft portion and located at overlapping longitudinal positions along the length of said elongate shaft portion, wherein said first and second key combination elements are each pivotable about a pivot axis;
- and
- wherein insertion of said key device into said keyway aligns one of said first and second key combination elements with said plug pin to urge said plug pin to the shear line to allow rotation of said plug and the other one of said first and second key combination elements abuts against a portion of said plug and not against said plug pin, and wherein said first and second key combination elements are independently active biasing elements, capable of providing a biasing force independently from one another.
