Abstract
The present invention is directed to key assemblies and their mating locks, and more particularly, to keys with mutually compressible, actuating elements capable of being continuously positioned axially within apertures in a key blade.
Claims13
A key assembly comprising:
- a key blade, the key blade being substantially flat and having a first surface and a second surface, the key blade configured to be inserted into a mating lock;
- an aperture in the key blade, the aperture having an axis;
- a cap having an outer surface, captured in the aperture for continuous axial travel between a first limit extending out of the first surface and a second limit recessed within the aperture;
- and
- a base having an outer surface, captured in the aperture for continuous axial travel between a first limit extending out of the second surface and a second limit recessed within the aperture;
- and
- a magnet associated with the base, the cap or both, the magnet having sufficient magnetic strength to attract or repel a movable part of the key, or the lock from a locking position to an unlocking position in the lock, or in both the key and the lock.
4 more elements
A lock assembly comprising:
- a barrel;
- a column extending from the barrel, the column having at least two column apertures;
- a cylinder configured to rotate within the barrel, the cylinder including a guide way sized and configured to receive a key blade, the cylinder including a cylinder aperture axially registered with the column aperture when the lock assembly is locked, and movable out of registration with the column aperture with the key blade to unlock the lock assembly;
- a first and a second pin captured by one of the cylinder and the column, the pins having a first portion slidable in the cylinder aperture and a second portion slidable in the column aperture, the pins normally being biased to a locking position with the first portion within the cylinder aperture and the second portion within the column aperture to lock the cylinder relative to the barrel;
- a magnetically influenced part associated with the first pin, the magnetically influenced part being movable responsive to a magnetic field provided in the guide way to move the first pin to an unlocking position;
- and
- a mechanically influenced part associated with the second pin, the mechanically influenced part being movable responsive to a non-magnetic force provided in the guide way to move the second pin to an unlocking position.
4 more elements
The combination of a key assembly and a lock assembly:
- the lock assembly having:
- a barrel;
- a column extending from the barrel, the column having a column aperture;
- a cylinder configured to rotate within the barrel, the cylinder including a guide way sized and configured to receive a key blade, the cylinder including a cylinder aperture axially registered with the column aperture when the lock assembly is locked, and movable out of registration with the column aperture with the key blade to unlock the lock assembly;
- a first and a second pin captured by one of the cylinder and the column, the pins having a first portion slidable in the cylinder aperture and a second portion slidable in the column aperture, the pins normally being biased to a locking position with the first portion within the cylinder aperture and the second portion within the column aperture to lock the cylinder relative to the barrel;
- a magnetically influenced part associated with the first pin, the magnetically influenced part being movable responsive to a magnetic field provided in the guide way to move the first pin to an unlocking position;
- and
- a mechanically influenced part associated with the second pin, the mechanically influenced part being movable responsive to a non-magnetic force provided in the guide way to move the second pin to an unlocking position;
- and
- the key assembly comprising:
- a key blade, the key blade being substantially flat and having a first surface and a second surface, the key blade configured to be inserted into a mating lock;
- an aperture in the key blade, the aperture having an axis;
- a cap having an outer surface, captured in the aperture for continuous axial travel between a first limit extending out of the first surface and a second limit recessed within the aperture;
- and
- a base having an outer surface, captured in the aperture for continuous axial travel between a first limit extending out of the second surface and a second limit recessed within the aperture;
- and
- a magnet associated with the base, the cap or both, the magnet having sufficient magnetic strength to attract or repel a movable part of the key, or the lock from a locking position to an unlocking position in the lock, or in both the key and the lock.
