Gun trigger mechanism

A gun trigger mechanism comprising

• a gun frame,
• a trigger mounted on the frame, the trigger being pulled to fire the gun,
• a gun hammer movable between a fully-cocked position, from which the gun is intended to be fired by release of the gun hammer, and a firing position, the gun hammer being biased from the fully-cocked position toward the firing position,
• an interlock mounted on the gun frame, the interlock being movable between
• a locked state in which it acts to block movement of the gun hammer toward the firing position, and
• an unlocked state in which it does not act to block the movement of gun hammer toward the firing position,
• wherein the interlock is biased toward its locked state and is coupled to the trigger, such that the interlock blocks the gun hammer when it is released from reaching the firing position, unless the trigger is concurrently pulled,
• a means for revolving a cylinder to thereby advance a subsequent chamber,
• a cylinder latch that locks a cylinder of the gun and prevents it from rotating, at least when the gun hammer is in the fully-cocked position, the cylinder latch being pivotally mounted on the frame upon a pivot pin, and the interlock is pivotally mounted on the frame upon the same pivot pin as the cylinder latch is pivotally mounted upon,
• the interlock is pivotally mounted on the gun frame and is biased to rotate in a first rotational direction, and
• the interlock mounts a trigger arm perpendicular to the plane of the interlock, the trigger arm adapted to engage the trigger, and
• a trigger-biasing spring mounted to the gun frame, the trigger-biasing spring engaging the trigger arm and thereby biasing the interlock toward the locked state,
• the trigger is pivotally mounted by a pivot pin on the gun frame,
• the trigger includes a nose that is adapted to engage the trigger arm of the interlock on a first side of the trigger arm, the first side is opposite a second side of the trigger arm that is engaged by the trigger-biasing spring,
• the trigger-biasing spring biases the trigger arm, to urge the interlock to pivot in a first rotational direction, and the trigger arm transfers bias to the nose of the trigger, which is thereby urged to pivot in a second rotational direction, opposite the first,
• the trigger-biasing spring is a leaf-spring that is mounted on the gun frame at a first end and is free at a second end,
• the trigger pivots about the pivot pin without the nose engaging the free end of the leaf-spring,
• the trigger arm above the interlock engages both of the free end of the leaf spring and the nose of the trigger, and
• the arm is urged into engagement with the nose by the leaf-spring.

A gun trigger mechanism comprising

• a gun frame,
• a trigger mounted on said gun frame,
• a gun hammer mounted on said gun frame and movable toward a firing position, and
• an interlock mounted on said gun frame, said interlock being continuously biased toward a locked state to block movement of said gun hammer toward the firing position, said interlock being movable against the bias away from the locked state when said trigger is pulled.

A gun trigger mechanism comprising

• a gun frame,
• a trigger mounted on said gun frame and biased toward a position at which it may be pulled against the bias by a finger of a gun operator,
• a gun hammer movable between a fully-cocked position and a firing position, said gun hammer being biased toward an at-rest position interposing the fully-cooked and firing positions,
• a hammer sear formed in said gun hammer,
• a trigger sear formed in said trigger, said trigger sear being urged by the bias on said trigger to engage said hammer sear when said gun hammer is in the fully-cocked position, and
• a blocking device biased at all times to block movement of said gun hammer from the fully-cocked position, the at-rest position or any position therebetween, past the at-rest position to prevent said gun hammer from reaching the firing position unless said trigger is being concurrently pulled.

A gun trigger mechanism comprising

• a gun frame having a frame shoulder,
• a gun hammer movable between a fully-cocked position and a firing position and being pivotally mounted on said gun frame,
• a hammer shoulder formed in said gun hammer, said hammer shoulder movable toward said frame shoulder when said gun hammer moves toward the firing position, said hammer shoulder opposing said frame shoulder, and
• an interlock movable between a locked state at which it cooperates with said frame shoulder forming a stop that blocks movement of said hammer shoulder thereby preventing said gun hammer from moving toward said firing position, and an unlocked state at which it does not block said hammer from moving toward said firing position, said interlock being continuously biased toward the locked state and being coupled to a trigger and movable by said trigger against the bias and towards the unlocked state when the trigger is pulled.

The gun trigger mechanism comprising a gun frame,

• a gun hammer pivotally mounted on said gun frame and movable between a fully-cocked position and a firing position, said gun hammer being biased from the fully-cocked position toward the firing position,
• a trigger operably connected to said gun hammer,
• a rebound device operably connected to said hammer to urge said hammer away from the firing position towards an at-rest position, and
• an interlock mounted on said frame and continuously biased toward a locked state at which it blocks movement of said gun hammer past the at-rest position when said gun hammer is moved from the fully-cocked position, the at-rest position or any, position therebetween, towards the firing position unless the trigger is being concurrently pulled.

A firing interlock for a gun comprising

• a body having a first end and a second end, said body being adapted to mount on a frame of a gun adjacent a trigger and a hammer of the gun,
• a pivot formed in said body adjacent said first end,
• a hammer arm extending from said body adjacent said second end, said hammer arm being adapted to interpose the frame and the hammer of the gun when biased to a locked state, and
• a trigger arm extending from said body interposed between said pivot and said hammer arm, said trigger arm being adapted to engage a trigger-biasing spring and the trigger of the gun, and transfer the bias of said trigger-biasing spring to the trigger.

A gun trigger mechanism comprising

• a gun frame,
• a trigger mounted on said gun frame,
• a gun hammer mounted on said gun frame and movable toward a firing position,
• an interlock mounted on said gun frame, said interlock being biased toward a locked state to block movement of said gun hammer toward the firing position, said interlock being movable against the bias away from the locked state when said trigger is pulled, and
• a trigger-biasing spring engaging said interlock to bias said interlock toward its locked state, said interlock engages said trigger and transfers said bias of said trigger-biasing spring to said trigger, said trigger biasing spring terminates at a position in spaced relation with said trigger.

A gun trigger mechanism comprising

• a gun frame,
