A toy hand grenade has a plurality of bores which receive soft darts. A launcher is received in each bore and is spring loaded. An actuator retains the launchers in a spring-loaded, unactuated position. The actuator is displaceable relative to the body to release the launchers and substantially concurrently eject the darts from the hand grenade. A pin or a clip may be employed to lock the actuator in a locked position. A timer is employed to delay actuation of the actuator to release the launchers and eject the darts from the hand grenade. A sandbag ring is imposed to ensure proper orientation and stability of the hand grenade for the timer actuated feature. |

Jahangir S. Rastegar; Thomas Spinelli; Richard T. Murray |
An inertia igniter including a mechanical delay mechanism having two or more members which are movable under different acceleration conditions to sequentially move a movable member upon sequential movement of the two or more members and an ignition member actuatable by the movable member such that movement of the movable member by the two or more members ignites the ignition member. The movable member can be movable by one of translation and rotation. The inertia igniter can further comprise an impact mass releasably movable in the housing, wherein the impact mass is released and movable by movement of the movable member to impact the ignition member. The inertia igniter can also further comprise a stop member for preventing movement of the impact mass until the movable member has moved a predetermined distance. |
