Weapons storage system and locking mechanism

A locking mechanism for a rotating cylindrical assembly, comprising:

• a shaft fixed to a base;
• a sear hub concentrically fixed to the shaft and having a notch on a peripheral surface;
• a stop shaft that rotates on the rotating cylindrical assembly between a first locked position and a second unlocked position;
• a stop plate concentrically fixed to the shaft that has a first arm that engages the stop shaft in the first locked position, and a second arm that engages the stop shaft in the second unlocked position;
• a sear lock having a projection that pivots into and out of the notch in the sear hub;
• and
• a lock body pivotally attached to the sear lock that causes the projection of the sear lock to engage and disengage into and out of the notch in the sear hub.

A locking mechanism for a rotating cylindrical assembly, comprising:

• a housing having an upper wall, a lower wall and a side wall;
• a main shaft fixed through the lower wall to a base;
• a sear hub having a notched indentation about a peripheral surface, the sear hub being concentrically fixed to the main shaft;
• a stop shaft that rotates on the rotating cylindrical assembly between a first locked position and a second unlocked position;
• a stop plate concentrically fixed to the main shaft that has a first arm that engages the stop shaft in the first locked position, and a second arm that engages the stop shaft in the second unlocked position;
• a sear lock having a projection that pivots into and out of the notched indentation in the sear hub;
• and
• a lock body attached to the sear lock that engages and disengages the projection of the sear lock into and out of the notched indentation in the sear hub,
• wherein when the projection of the sear lock is actuated by the lock body to engage the notched indentation in the sear hub, the rotating cylindrical assembly is blocked from rotating relative to the base.
