Abstract

A safety catch is provided for firearms, such as pistols and revolvers, having a firing hammer (11) with a thrust spring (13) associated with a spring-holder rod (14) with a free end (16) of a noncircular cross section. The safety catch includes a safety pin (19), which is aligned with the free end of the spring holder (14) and is capable of axial, rotary translatory movements that can be controlled by a defined contour key (20) for a longitudinal blocking of the spring-holder rod (14), so as to prevent the arming and the action of the firing hammer when it is released and inhibits the functioning of the gun in the absence of the key.

Claims

1. 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 a 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 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.

2. A safety catch in accordance with claim 1, wherein the safety pin has a defined contour terminal portion for coupling with a control defined contour key, said safety pin being stressed in an axial direction by a safety spring acting in the manner of normally maintaining the safety pin in the passive, lowered position.

3. A safety catch in accordance with claim 1, wherein the safety pin is mounted in said housing of said safety body providing the possibility of the safety pin rotating by a certain angle around a geometric axis, and having lateral cam portions interacting with fixed companion cams, sad fixed companion cams being provided in said housing for a translation of said safety pin between the passive and active positions simultaneously with the rotation of the safety pin with the defined contour key.

4. A safety catch in accordance with claim 1, wherein 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.

5. A safety catch in accordance with claim 1, wherein a burglar-proof reinforcement part is provided in a safety body, around and at the level of said defined contour portion.

6. A safety catch in accordance with the above claims, wherein the safety body is fixed to the stock of the gun and the safety pin is held in the body, said safety pin being removable only when the safety pin is in the passive position.

7. A gun device, comprising:

a firing hammer rotating on an axis between a released position and an armed position;

a thrust spring;

a firing hammer rotating against the action of said thrust spring,

a spring-holder rod, said thrust spring being associated and guided with said spring-holder rod, the spring-holder rod having an end connected eccentrically to said firing hammer and an opposite free end of a noncircular cross section;

a safety body fixable to a part of a stock of a gun in association with a 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 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.

8. A gun device in accordance with claim 7, further comprising a sphere, said safety body being fixed to the stock of the gun and said safety pin being held in said safety body with said sphere to make possible disassembly only when the safety pin is in the passive position, said sphere being mounted radially in the safety body and interfering with the stock of the gun when the safety pin is in the active position.

9. A gun device in accordance with claim 7, wherein said safety pin has a defined contour portion and a rotatable terminal plug for preventing access to and grasping of the pin with working tools other than a key corresponding to said defined contour portion, said plug being having an antidrill conical head, said plug being applied to said safety pin on a side of said defined contour portion.
