Projectile launcher with barrel breech lock mechanism

A projectile launcher that includes a launcher body containing a firing pin assembly or a valve assembly, a primary handgrip integrally formed or attached to the launcher body, an upper rail, a front ring assembly attached to the upper rail, a barrel breech, and a breech void area between the launcher body and the front ring assembly, the barrel breech being pivotally connected to the front ring assembly and configured to fit inside the breech void area so that the barrel breech may be axially aligned with the launcher body, the projectile launcher further comprising;

• a. a stop surface formed on the barrel breech;
• b. a lower rail extendingly mounted on the launcher body and under the breech void area, the lower rail includes a distal end and a proximal end;
• c. a latch plate axially aligned with and located under the lower rail, the latch plate being pivotally attached to the distal end of the lower rail;
• d. an alignment pin coupled to the latch plate and extending through the lower rail, the alignment pin configured to engage the stop surface formed on the barrel breech when the latch plate is axially aligned with the lower rail and the barrel breech is axially aligned in the breech void area, the alignment pin being configured to disengage the stop surface on the barrel breach when a proximal end of the latch plate is rotated downward;
• e. a front handgrip attached to said latch plate;
• f. a first lock mechanism disposed between the lower rail and the latch plate, the first lock mechanism configured to automatically lock the latch plate in axial alignment with said lower rail and configured to be selectively moved to unlock the latch plate from the lower rail to enable the proximal end of the latch plate to be forcibly pulled downward from the lower rail using the front handgrip;
• and
• g. a second lock mechanism located between the latch plate and the lower rail, the second lock mechanism includes a biased blocking member configured to prevent rotation of the proximal end of the latch plate from the lower rail, the blocking member being attached to a button located on the lower rail and above tire front handgrip, when the button is moved on the lower rail, the blocking member moves to an unblocking location thereby enabling the proximal end of the latch plate to rotate downward.
