Abstract
A shutter locking assembly that has a bolt carriage with a bolt slidingly engageable with the bolt carriage and a biasing (actuator) means operatively connected to the bolt member and the bolt carriage. The bolt carriage is inserted into a cavity of a shutter slat, and the action of moving the shutter slat between an up (open) position and a down (locked) position, causing the bolt to be moved between an extended position and a retracted position. When the shutter slat is in a down (locked) position the bolt engages with a bolt receiving opening adjacent to the shutter slat, and when in an up (open position) the bolt is retracted
Claims16
A shutter locking assembly including:
- a bolt carriage;
- a locking bolt slidingly engageable with the bolt carriage between an extended position and a retracted position;
- a biasing (actuator) means, being a leaf spring or torsional spring, operatively connected to the locking bolt and the bolt carriage;
- the bolt carriage being inserted into a shutter slat cavity,
- the locking bolt being movable by movement of the shutter slat between an up (open) position and a down (locked) position, by action of the biasing (actuator) means within the shutter slat cavity, the shutter slat when in a down (locked) position urges against the biasing (actuator) means, the biasing (actuator) means forcing the locking bolt out to extend the locking bolt to engage with a locking bolt receiving opening adjacent to the shutter slat, and when in an up (open) position the locking bolt is retracted.

A roller shutter assembly which includes a plurality of shutter slats pivotally or hingedly interconnected with one another, at least one shutter slat having a cavity, a locking assembly including:
- a shutter slat having a cavity;
- a bolt carriage;
- a locking bolt slidingly engageable with the bolt carriage between an extended position and a retracted position;
- a biasing (actuator) means, being a leaf spring or torsional spring, operatively connected to the locking bolt and the bolt carriage;
- the bolt carriage being inserted into a shutter slat cavity,
- the locking bolt being movable by movement of the shutter slat between an up (open) position and a down (locked) position, by action of the biasing (actuator) means within the shutter slat cavity, the shutter slat when in a down (locked) position urges against the biasing (actuator) means, being a spring means, the biasing (actuator) means forcing the locking bolt out to extend the locking bolt to engage with a locking bolt receiving opening adjacent to the shutter slat, and when in an up (open) position the locking bolt is retracted.
