The invention relates to a swirl projectile percussion fuse with one of one under the influence of a delay mechanism Oscillating link made of an actuatable safety device, which is a normally secured swiveling ratchet for securing an axially displaceable primer carrier and one on one End of a locking axis which simultaneously forms the axis of rotation of the oscillating member Has locking part for securing an ignition charge carrier displaceable in the transverse direction.

The invention is that the locking axis at its other end also with a Locking part is provided, which serves to secure the swivel bolt, such that the delayed when firing Unlocking of the swivel bolt and the ignition charge carrier takes place suddenly at the same time.

Impact fuses are known in which the oscillating member itself is a locking member with its own safety function is. According to the invention, however, the vibrating member does not exercise directly, but only indirectly the backup function off. The effect of this is that in the case of the known detonators, the two Fuses for the firing pin and the firing channel one after the other while they are according to the invention be released suddenly at the same moment. The advantage of this simultaneous release of both fuses lies in the greater security after the launch, since both fuses up to complete unlocking of the projectile are fully effective, which is what the known detonators mentioned is not the case.

In the drawing, an embodiment of the igniter according to the invention is illustrated.

Fig. 1 is a vertical section of the with a Safety device provided with twist projectile percussion fuse;

F i g. 2 and 3 are horizontal sections according to the line H-II in Fig. 1, showing certain parts of the safety device in the locked and unlocked state;

F i g. 4 and 5 are similar sections according to the line IV-IV in Fig. 1, the other parts of the safety device show in the locked and unlocked state, and

F i g. 6 and 7 are similar sections according to the line VI-VI in Fig. 1, again showing different parts show the safety device in the two states mentioned.

The swirl projectile percussion fuse according to FIG. 1 has a striker 1, an inertial mass 2, which in Swirl projectile percussion fuse with safety device

an axial, stepped bore of the igniter body 3 is guided and by a compression spring 4 in its rearward position or rest position is held, a primary detonator provided in this inertial mass 5, an ignition charge 6 and a carrier 7 for the latter, which is guided transversely in the igniter body 3. The igniter also has a mechanical safety device which retards the ignition of the ignition charge on, the downpipe safety device of at least 50 meters in relation to the firearm guaranteed. This safety device has a toothed sector 8 with which a pinion 9 meshes, which forms a single piece with a gear 9 α (FIG. 1), an oscillating delay element 10, which by means of its two beak-shaped ends 10 α cooperates with the gear 9 α, one in With respect to the tooth sector 8 coaxial and firmly connected with this locking axis 11 and one as Rocker arm formed latch 12.

The two ends of the locking shaft 11 are designed as locking cams which, in the locked state (FIGS. 2, 4 and 6), hold the bolt 12 and the carrier 7 provided with the ignition charge 6 in their rest positions.

The locking and unlocking members of the safety device are relative to their movements at the same time delayed and act on the carrier 7 and on the inertial mass 2. In the locked state is any premature effect of the inertial mass 2, that of counter-impacts, side impacts, speed decelerations etc. in the cannon barrel or over a distance of at least 50 meters

Claims (2)

the mouth of the same could be caused completely. Before the projectile is fired, the safety device is secured in its entirety by means of bolts, not shown here. During the launch, the tooth sector 8, under the influence of centrifugal force, tends to move in the direction of FIG. 4 drawn arrow A to execute a pivoting movement. Its movement in this direction is, however, delayed by the gear wheel 9 α ίο, which can only rotate if it gives the delay element 10 an alternating oscillating movement. The toothed sector 8 thus executes a delayed movement in the direction of arrow A and finally reaches its position in FIG. 5 unlocked position shown. Since the toothed sector 8 is firmly connected to the locking axle part, the latter is rotated at the same time and thus moves from its locking position according to FIG. 2 and FIG. 6 in their unlocked position according to FIG. 3 or FIG. 7. Under the influence of the centrifugal force, the bolt 12 is moved from its locking position according to FIG. 2 transferred to its unlocked position according to FIG. 3, whereby the inertial mass 2 is unlocked and from now on on the occasion of a sudden delay that occurs when the projectile hits an obstacle and causes the ignition, in that the detonator 5 in turn opens impact pin 1. At the same time, the carrier 7 with the ignition charge 6 has moved from its locking position according to FIG. 6 into its unlocking position according to FIG. Paientanspjräihe: 1. Swirl projectile percussion fuse with one of one under the influence of a delay · ", Mechanism standing vibrating link from actuatable ft Safety device, which is a normally secured swivel bolt for securing one axially displaceable primer carrier and one at one end a locking axis which simultaneously forms the axis of rotation of the oscillating member Locking part for securing an ignition charge carrier which can be displaced in the transverse direction having, characterized in that the locking shaft (11) is also provided with a locking part at its other end, which is used to secure the swivel bolt (12) in such a way that the delayed unlocking when firing the swivel bolt and the ignition charge carrier suddenly at the same time he follows. 2.
