Definitions
- the invention relates to a projectile fuse with a safety device comprising a first ignition means in a housing on which a rotor is rotatably mounted with a second ignition means which can be pivoted via the first ignition means to form an ignition chain, and with a delay charge which can be moved into the ignition chain.
- Such a safety device is described in DE 26 40 782 C3 and in DE 31 07 110 A1. If the ignition device has an ignition delay, the ignition chain always works with the ignition delay. In any case, depending on the application, it is not possible to work with or without ignition delay.
- DE-AS 10 65 758 discloses a projectile detonator in which there is a free space between a squib and the detonator on the rotor which can be bridged by the squib. A delay pill can be inserted into the free space via a slide if an ignition delay is desired.
- the structure of this projectile detonator appears technically complex and complicated. In the underside of the rotor there is a groove in which the squib, the retardation pill and the transmission pill can be moved one above the other by means of separate slides under spring force.
- the object of the invention is to propose a projectile detonator with a safety device of the type mentioned in the introduction, in which the same ignition chain can be operated either with an ignition delay or without ignition delay and in which the ignition chain is constructed in a space-saving manner by simple components which ensure reliable operation .
- This new projectile detonator has ignition means that are simple in construction and have individual, interchangeable parts that can be used and replaced without great technical effort. These individual parts are easy to manufacture and assemble, which increases the overall economy in warehousing and production. If ignition without ignition delay is provided, then the slide is moved so that the delay charge is outside the ignition chain when the rotor is in focus. If, on the other hand, an ignition with ignition delay is provided, the slide is moved so that the delay charge is in the ignition chain.
- the delay charge is preferably neither in the free space nor above the ignition means.
- the slide is preferably mounted on the housing. However, it could also be mounted on the rotor itself.
- An ignition device (2) here an ignition transmitter, is arranged in a housing (1).
- a segment-shaped rotor (4) is pivotally mounted on the housing (1) on an axis (3) and is U-shaped by a recess (8) made transversely to the axis of rotation (3).
- the rotor (4) carries an igniter (5) in a bore (5.1) parallel to the axis of rotation (3) in a first leg (4.1) located at the top in FIG.
- a detonator (6) is inserted in the second leg (4.2) located at the bottom in FIG. 3 in a second bore (6.1), which is again parallel to the rotor axis of rotation (3).
- the axis of rotation (3) of the rotor (4) is provided in the remaining web (4.3) of the U design.
- a carrier (10) is pivotably mounted on the housing (1) on a further axis (9).
- a delay charge (11), which is formed by a delay piece, is arranged at one end of the carrier (10) projecting into the recess (9).
- the carrier (10) is loaded by means of a spring (12). It is locked by a locking pin (13) in the rotor (4) and in the arming of the rotor (4), if you want to work without ignition delay, locked (see Figure 1, 2).
- the rotor (4) is blocked by a pre-securing element (14) which engages in an indentation (15) in the circumference of the rotor (4) and by a wheel locking mechanism (16) with a flattened disc (17) engages in a second indentation (18) of the circumference of the rotor (4).
- the flattened disc (17) After the pre-securing element (14) has been released from the indentation (15) and the wheel inhibitor (16) has run off, the flattened disc (17) also releases the rotor (4) at its second indentation (18). It is then brought into focus (see FIGS. 2 to 5) under the action of a spring (19).
- the carrier (10) remains blocked by the locking pin (13), so that the delay charge (11) is outside the free space (7) (cf. FIGS. 2, 3). If the igniter (5) is initiated, then it ignites the detonator (6) across the free space (7), which in turn ignites the ignition means (2).
- the locking pin (13) is moved so that it releases the carrier (10). This then pivots under the force of the spring (12) so that the deceleration charge (11) is in the free space (7) (see FIGS. 4, 5). After initiating the igniter (5), the delay charge (11) is ignited. After its delay time, this ignites the detonator (6), which in turn ignites the ignition means (2).
- the delay charge (11) can be pivoted into the ignition chain before, during or after the pivoting of the rotor (4) from the securing position to the arming position.
- the delay charge (11) stands before it is pivoted outside the free space (7) and not above the ignition means (2).
- the delay charge (11) can be positioned above the ignition means (2) before pivoting.
- the rotor (4) in focus then swings the igniter (5) and the detonator (6) above or below the delay charge (11). If an ignition without ignition delay is desired in this case, then the carrier (10) is moved so that the delay device (11) goes out of the ignition chain. This can be done before, during or after the transition of the rotor (4) from securing to arming.
- the delay charge (11) is regularly in a position protected by the two legs (4.1, 4.2) of the rotor (4).
