Safety catch for pistols

A safety catch for firearms such as pistols and revolvers having a firing hammer rotating on an axis between a released position and an armed position against the action of a thrust spring, the thrust spring being associated and guided with a spring-holder rod, the spring-holder rod having an end connected eccentrically to the firing hammer and an opposite free end of a noncircular cross section, the safety catch comprising:

• a safety body fixable to a part of a stock of the firearm in association with said free end of the spring-holder rod, said safety body defining a housing;
• a safety pin mounted in a housing of the safety body in an arrangement that is aligned with a lower end of the spring holder rod and is capable of axial, rotary translatory movements;
• and
• a defined contour key for access and coupling to a part of the safety pin for the rotary translatory movements of the safety pin between a passive, lowered position, which does not affect the spring-holder rod for a normal functioning of the gun, and an active, raised position for the longitudinal blocking of the spring-holder rod for blocking the firing hammer in the released position and inhibiting the functioning of the gun;
• said safety pin has a top wall turned towards the lower end of said spring-holder rod, and in which in the top wall there is provided a hole having a cross section equal to that of the lower end of the spring-holder rod, said hole being aligned and coinciding with a lower end of the spring holder only when the safety pin is in the passive, lowered position, said hole being misaligned with respect to the rod for the interception of same by the safety pin when said safety pin is in the active, raised position.

A firearm comprising:

• a stock;
• a firing hammer rotatable on said stock between a released position and an armed position;
• a thrust spring biasing said firing hammer toward said released position;
• a spring-holder rod guiding said thrust spring, said spring-holder rod having a first end in contact with said firing hammer, said spring-holder rod having an opposite second end;
• a safety body fixable in said stock and defining a bore;
• a safety pin mounted in said bore of the safety body and contactable with said second end of said spring-holder rod, said safety pin being movable between a passive and an active position, said active position arranging said spring-holder rod to hold said firing hammer fixed, said passive position allowing movement of said firing hammer between said released position and said armed position;
• a key engageable with said safety pin for moving said safety pin between said active and said passive positions;
• a release member movable in said stock between a first position and a second position, said release member engaging said safety pin with said stock in said first position, said release member disengaging said stock and said safety pin in said second position, said release member and said safety pin being shaped to fix said release member in said first position when said safety pin is in said active position.
