Abstract:
A pry-proof gun port for shielding a gun whenever the gun port is in a closed position, and for permitting a bullet of the gun to be discharged through the gun port whenever the gun port in an open position, the pry-proof gun port comprising:a. a frame for mounting the pry-proof gun port to a support structure, the frame including an exterior mount plate that defines a discharge port dimensioned to support a closure shield; b. a push rod having an exterior end of the push rod secured to a peripheral region of the closure shield, the push rod having an intermediate portion passing through a chamber of the frame, and the push rod having an interior end opposed to the exterior end of the push rod; c. a lock shaft adjustably secured within a lock chamber defined within the interior end of the push rod, the lock shaft defining a raised exterior end opposed to an interior button end and a notch between the raised exterior end and the interior button end; d. a lock rod secured within a throughbore in the interior end of the push rod perpendicular to the push rod and lock shaft so that an upper end of the lock rod abuts a shoulder of the chamber of the frame whenever a lower end of the lock rod contacts the raised exterior end of the lock shaft; and, e. the frame, push rod, lock shaft and lock rod being cooperatively dimensioned so that whenever the lock shaft is moved toward the exterior end of the push rod, the lower end of the lock rod moves into the notch of the lock shaft and the upper end of the lock rod moves out of abutment with the shoulder of the chamber of the frame so that the push rod may then move toward the exterior mount plate to push the closure shield out of the discharge port of the exterior mount plate to permit rotation by the push rod of the closure shield away from the discharge port to permit passage of a bullet through the discharge port.
