Abstract
A lock mechanism is provided for engaging a lock bolt within a bolt cavity. In one embodiment, the lock bolt is disposed within a strike pocket of a door frame and the bolt cavity is disposed within a strike housing assembly of a door. A shutter plate slideably covers the bolt cavity when the lock bolt is not engaged within the bolt cavity. The shutter plate is configured to be in a normally-closed position and is slidable to an open position when the lock bolt is sufficiently proximate to the bolt cavity, to allow the lock bolt to enter the bolt cavity.

A lock mechanism for engaging a lock bolt within a bolt cavity, the lock mechanism comprising:
- a shutter plate that slideably covers the bolt cavity when the lock bolt is not engaged within the bolt cavity, the shutter plate configured to be in a normally-closed position and slidable to an open position to allow the lock bolt to enter the bolt cavity when the lock bolt is sufficiently proximate to the bolt cavity;
- a strike pocket that contains the lock bolt and a strike housing assembly that contains the bolt cavity;
- and
- wherein the strike pocket further comprises a magnet that attracts a piston within the strike housing assembly such that when the magnet is sufficiently close to the piston, the piston moves and actuates a shutter lever latch within the strike housing assembly, the shutter lever latch configured to unlock the shutter plate upon actuation by the piston, allowing the shutter plate to slide open.
A lock mechanism for engaging a lock bolt within a bolt cavity, the lock mechanism comprising:
- a strike pocket comprising a lock bolt and a magnet;
- a strike housing assembly comprising a bolt pocket, the lock bolt engageable within the bolt pocket;
- a shutter plate slideably affixed over the bolt pocket to prevent the bolt pocket from accumulating debris;
- a shutter lever latch disposed on the strike housing assembly, the shutter lever latch comprising a stop end that contacts the shutter plate and maintains the shutter plate in a normally-closed position until the shutter lever latch rotates open;
- a piston attached to a piston end of the shutter lever latch, the piston comprising a metallic head attractable to the magnet when the piston is in close enough proximity to the magnet, such that when the piston approaches the magnet, the piston end of the shutter lever latch rotates the stop end of the shutter lever latch to unlock the shutter plate, permitting the shutter plate to open.
A lock mechanism for engaging a lock bolt within a bolt cavity, the lock mechanism comprising:
- a shutter plate that slideably covers the bolt cavity when the lock bolt is not engaged within the bolt cavity, the shutter plate configured to be in a normally-closed position and slidable to an open position to allow the lock bolt to enter the bolt cavity when the lock bolt is sufficiently proximate to the bolt cavity;
- a strike pocket that contains the lock bolt and a strike housing assembly that contains the bolt cavity;
- and
- wherein the shutter plate further comprises a shutter slide tab extending from the shutter plate, the shutter slide tab engagable with a shutter slide engagement tab disposed within the strike pocket such that when the shutter slide tab contacts the shutter slide engagement tab, the shutter plate slides open to uncover the bolt cavity.
