Description

The invention relates to a device for reducing the Rate of fire of automatic weapons.

Technology has made use of the advantages in various ways, a reduction in the rate of fire, especially in the case of continuous fire, which is more automatic Weapons, brings with it. The invention makes use of this to achieve such Reduction of the rate of fire in other contexts in the construction of firearms well-known spring-actuated hammer, which for the new: purpose in novel Way is formed and arranged. To solve this problem the new device to reduce the rate of fire of automatic weapons characterized in that that a well-known spring-loaded hammer acts on the firing pin, in which the The point of application of the spring is in its tensioned position in front of the pivot point of the hammer and is offset from it in such a way that the spring axis is practically in line Spring attack point hammer pivot falls.

The inventive arrangement of the spring-loaded hammer is achieved that the smallest torque from the spring in the starting position of the Hammer is exercised, the largest, however, in the end position, i.e. when touched of the firing pin. This deceleration torque is achieved in the simplest way by that the point of application of the spring in the cocked position on the hammer in such a way. arranges' that the spring axis runs approximately through the hammer pivot point, of course while avoiding a dead center. The start of the is confused by the small torque Hammer movement, a considerable delay in firing is achieved. Nevertheless it is on At the end of the movement, the energy is high enough to drive the firing pin forward with certainty. The invention thus makes it possible to reduce the rate of fire without compromising security to question the ignition.

At the same time, there is also another advantage, that of the deceleration movement to = related. Because the hammer torque is low at start-up, the pressure of the Hammer on the control edge of the lock accordingly slightly. At a Lock movement through the shot, the particularly small transverse pressure is desired, the the invention offers as an additional advantage.

It is in the drawing in a basic embodiment shown.

Fig. I shows the hammer in its cocked position, Fig. 2- at the moment the ignition.

A hammer i is rotatable around the pin 2, and the pin 3 engages Tension spring 4, the other end 5 of which is fixedly mounted. The center of the attack spigot 3 'for the spring 4 is only the distance a1 from the center of the pivot 2 for the hammer i offset. The spring force in the position of Fig. I is denoted by P1. The hammer lies against the leading edge 6 of the lock 7, in which the firing pin 8 acts in the usual way on the cartridge 9, the projectile after ignition by the Run io is driven.

At the moment of ignition, the pin a has the greatest distance a2 reached by the engagement pin 3 of the spring 4, the spring force of which riunmühr P is. Obvious a2 is much larger than a1, while P1 is larger than P2. Let the torques easily disregard one another in such a way that a very low starting moment and there is a significantly higher final torque.

PATENT CLAIM: Firearm with a spring-loaded firearm on the firing pin Hammer acts where the point of application of the spring is in its tensioned position in front of the pivot point of the hammer and is offset from him in such a way that the spring axis is practical falls in the line spring attack point-hammer pivot point, as a means of reducing the rate of fire with continuous fire from automatic weapons.
