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.
Claims18
-26. (canceled)
A lock apparatus, comprising:
- a spindle including a channel, an aperture, and a chamber in communication with the channel and the aperture;
- a locking bar movably positioned in the channel;
- and
- a plurality of rotatable elements rotatably mounted in the chamber, 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
- an opening 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 and the wafer housing is operable to selectively prevent movement of the locking bar from the first position to the second position.
