Description

461 478 According to the invention, this object is achieved by the rotor is mounted on a holder carrying an ignition transmitter, that the holder is axially displaceably arranged in the housing, hole f is read by the rotor in its secured position and released in the rotor unsecured position for displacement in axial direction, and that in radial movable bodies are provided, which at radial displacement actuation of the holder in the axial direction, whereby the igniter in the rotor strikes the spark plug.

In the event of a target impact with a steep impact angle, the ignition the agent against the spark plug due to the inertia of the holder and the rotor hot. At a flat angle of impact or unequal spark plug hit the bodies are displaced by their inertia in the radial direction.

In this way an additional axial pressure is exerted on the holder.

The invention will be described in more detail below with reference to the accompanying drawings, on which Figure 1 is a longitudinal section through a spark plug in secured location; and in Figure 2 is a longitudinal section through the spark plug in unsecured location.

In a housing 1 a bottom screw 2 is screwed in, which shows a bottom 3. On the bottom screw 2 a cup 4 is fixed screwed, which contains a charge 5. Another cover plate 6 the charge 5 abuts the bottom 3.

The bottom 3 has several cut-outs 7, in which segment shaped wedge bodies 8 are inserted. The wedge bodies 8 are movable ' in radial direction R.

On the bottom 3 is a support part 9 which holds a bottom plate 10 in the housing 1. Attached to the support part 9 are guide pins 25, whereupon a holder 11 is slidably guided in the axial direction A. Using locking springs 12, the holder 11 is pressed with one edge 13 towards the bottom 3. The holder 11 has a chamfer 14 which is located opposite bevelled surfaces 15 on the wedge bodies 8.

On the holder ll are the first and second ignition transmitters 16 and 17 fasten. The ignition transmitter 17 engages deeply in the charge 5. On the holder 11, via a pin 18, is a rotor 19 rotatably mounted. The rotor 19 is locked in a secured position (see figure 1) f of a fuse shaft 20. On the rotor 19 a weight body 21 is formed. mad, which in a secured position abuts the bottom plate 10, so that axial displacement of the holder ll together with the tower 19 is not possible. f:

Claims (8)

A spark plug 23 projects into a recess 22 in the goktenp socket 10. The rotor 19 has a detonator 24 which in a secured position is pivoted away from the spark plug 23. After firing, the rotor 19 is released from the fuse shaft 20. This is then rotated, depending on its center of gravity, to an unsafe position, with the weight body 21 ending up in front of the recess 22 (see figure 2). The ignition chain formed by spark plug 23, detonator 24 and ignition transmitter 16, 17 is now closed. The detonator 24 is kept via the rotor 19 and via the holder 11 at a distance from the spark plug 23 by means of the locking springs 12. When the target strikes, the holder 11 is thrown forward together with the rotor 19, the holder 11 sliding on the guide pin 25. The detonator 24 strikes the spark plug 23. 21 .going into the recess 22. Ignition takes place. Since the ignition transmitter 17 engages deeply in the charge 5, ignition thereof is not prevented by the displacement of the ignition transmitter 17 together with the holder 11. Appearing at target impacts, especially at target impacts at a flat angle or at uneven spark plug hits, transversely directed forces, a part of the wedge bodies 8 is thrown towards the center of the spark plug, their bevelled surfaces 15 hitting the chamfer 14 and thereby with additional force throws the holder 11 with the rotor 19 and the detonator 24 against the spark plug 23. With the increasing mass of the wedge bodies 8, the function of the device is improved at flat angles of incidence. In other embodiments of the invention, balls or rollers can be used instead of wedge-shaped bodies 8. The rotor 19 can also be stored on the holder 11 in another way. It is important that the axial displacement of the holder 11 is transmitted to the rotor 19 supporting the detonator 24. Spark plug with a rotor carrying an igniter arranged in a housing, which is locked in a secured position but which after release is turned to an unsafe position, and with a spark plug, which ignites the igniter at target impact, characterized in that the rotor (19 ) is mounted on a holder (11) supporting an ignition transmitter (16, 17), that the holder (11) is axially displaceably arranged in the housing (1), is held by the rotor (19) in its secured position and is released in the rotor (19). unsecured position 461 478 for displacement in the axial direction, and that radially movable bodies (8) are arranged, which in the case of radial displacement (R) actuate the holder (11) in the axial direction (A), the igniter (24) in the rotor (19) strikes the spark plug (23).
