Wishbone a mortar and Granada Granada mortar can be fired from a mortar fuze with a pin of this type

摘要

Fuze active part for Granada mortar with the following characteristics: a) the fuze active part (8) comprises a detonator holder (9) which can pivot from a locked position to an on position; b) the holder detonator (9) is connected actively to a first security device (10), if used as provided, comprising a locking pin (12) loaded by a spring (11) which extends in the direction of the longitudinal axis (100) of Granada mortar (1) and corresponding with its first end (13) is supported by a shear pin (14); c) the shear pin (14) is disposed within a transverse bore (15) and has on its side facing the first end (13) of the locking bolt (12) having a guide contour (16), so that, in the secured position the holder detonator (9), the second end (17) of the locking bolt (12) is pressed against spring pressure (11) in a first recess (18) of the holder detonator (9) and prevents a tilting movement of the detonator holder (9) to its on position; d) the transverse bore (15) has a connecting bore (19), through which gases propellant charge produced during the firing of the Granada mortar (1) corresponding can reach the transverse bore and produce there a pressure increase which is sufficient to separate the portion (26) of the shear pin (14), equipped with the guide contour (16) of the remaining portion of shear pin (14) and move along the transverse bore (15) towards the outer wall (27) of Granada mortar (1), so that the locking pin (12) supported on the guide contour (16) with its first end ( 13), because the guide contour (16) is changed, it is pressed out of the first recess (18) of the holder detonator (9) and the carrier detonator (9) can be pivoted to its position.
