Abstract
The present disclosure provides for a lock cylinder having a rotatable spindle with at least one disc and at least one wafer housing rotatingly engaged therewith. A slidable wafer is carried on the wafer housing. A locking bar is operable to prevent rotation of the lock cylinder in a locked position and permit rotation of the lock cylinder in an unlocked position.
Claims17
A lock apparatus, comprising:
- a spindle including an aperture;
- a locking bar movably positioned relative to the spindle;
- and
- a plurality of rotatable elements rotatably mounted relative to the spindle, the plurality of rotatable elements including a disk, a wafer housing, and a wafer slidably coupled to the wafer housing;
- wherein each of the rotatable elements includes:
- a receiving portion sized and shaped to receive a portion of the locking bar;
- and
- a slot sized and shaped to receive a portion of a key;
- wherein each of the rotatable elements has a first position in which the receiving portion is not aligned with the locking bar, and a second position in which the receiving portion is generally aligned with the locking bar;
- wherein the wafer includes a lock extension sized and shaped to be received in the aperture;
- and
- wherein when the wafer is in the first position, the lock extension is generally aligned with the aperture and the wafer is movable between a first radial position in which the lock extension is received in the aperture and a second radial position in which the lock extension is not received in the aperture.

A lock apparatus, comprising:
- a spindle rotatably mounted in a support structure;
- a wafer housing rotatably mounted in the spindle;
- a wafer movably mounted to the wafer housing, the wafer operable to selectively couple the wafer housing to the spindle;
- a disk rotatably mounted in the spindle;
- and
- a locking bar having a first position in which the locking bar prevents rotation of the spindle with respect to the support structure, and a second position in which the locking bar does not prevent rotation of the spindle with respect to the support structure;
- and
- wherein each of the disk, the wafer, and the wafer housing is operable to selectively prevent movement of the locking bar from the first position to the second position;
- and
- wherein each of the disk, the wafer, and the wafer housing comprises a receiving portion sized and shaped to receive a portion of the locking bar, and is configured to prevent movement of the locking bar from the first position to the second position when the receiving portion thereof is misaligned with the locking bar.
