Dual safety fuze for grenade |
| 摘要 |
A hand grenade fuze includes a secondary safety feature in the form of a trigger pin inserted through the striker lever. One end of the trigger pin has an undercut portion. A slide bar is disposed in the fuze body and has a keyhole opening at one end for selectively engaging the undercut portion of the trigger pin. A trigger has one end connected to the slide bar and another end rotatably fixed to the fuze body. A spring biases the trigger away from the fuze body. When the trigger is depressed, the slide bar translates and releases the trigger pin, which releases the restraint on the striker lever. |

a fuze body; a striker lever rotatably mounted to the fuze body; a rotor assembly rotatably mounted to the fuze body; a spring that torsionally biases the rotor assembly; a pull ring having a pull pin that is inserted through the striker lever to restrain rotation of the striker lever and the rotor assembly; a trigger pin having a longitudinal axis and inserted through the striker lever to restrain rotation of the striker lever, one end of the trigger pin including an undercut portion; a slide bar disposed in the fuze body and having a keyhole opening at one end for selectively engaging the undercut portion of the trigger pin; a trigger having one end connected to the slide bar and another end rotatably fixed to the fuze body; and a second spring that biases the trigger away from the fuze body. |
