Patent attributes
A barrel breech lock and mechanism for a projectile launcher chat uses a launcher body, a lower rail extending forward and under the launcher's barrel breech and a pivotally mounted latch plate. Extending downward extending from the latch plate is a front handgrip. Disposed between the lower rail and the latch plate and directly above the front handgrip is a locking mechanism that selectively blocks rotation of the proximal end of the latch plate. In two embodiments, the locking mechanism is a biased lateral push button or a biased sliding button. When the lock mechanism is activated, the proximal end of the latch plate may be rotated downward by a twisting force applied via the from handgrip. Disposed between the proximal end of the latch plate and the barrel breech is a second lock mechanism that includes a pin. The end of the pin engages a stop surface formed on the barrel breech when axially aligned in the breech void area. The first lock mechanism can be easily activated with the hand holding the from handgrip. Because the first and second lock mechanisms must be sequentially activated in order to open the barrel breech, the operation of the projective launcher is safer.
