An apparatus actuatable under a rotary acceleration having a predetermined duration and magnitude. The apparatus including: a body having a first channel and a second channel, the second channel being disposed radially offset from the first channel; a mass disposed in the first channel, the mass having an arm disposed at a first end of the mass and the arm being rotatable from a first position in which the arm cannot move within the second channel to a second position in which the arm can move inside the second channel; a first biasing spring member having a first end connected to the body and a second end connected to the arm such that when the arm is subjected to the rotary acceleration greater than the predetermined duration and magnitude, the arm is biased to rotate from the first position to the second position; wherein the mass is connected to the arm such that the mass moves in the first channel and the arm moves in the second channel when the arm is biased into the second position.

ROCKER ARM DETONATOR
20170363400 · 2017-12-21 · ·

A rocker arm detonator is provided that includes a detonator head, which includes a pivotably arranged firing pin which is acted upon by a firing pin spring, and has a safety clip, which is pivotably disposed in the same direction of rotation as the firing pin from a starting position, in which it is pressed in the direction of the detonator head to a firing pin release position. To reliably avoid an unintentional detonation of the rocker arm detonator prior to its proper use, when the rocker arm detonator is not in use, the firing pin spring is in its untensioned state and may be tensioned by a separate tensioning lever as soon as the rocker arm detonator is to be properly deployed.

Safe and arm mechanisms and methods for explosive devices

A SAFE and ARM mechanism includes an elongated casing having a first end and a second end. A high-G force firing pin is arranged relatively near to the first end and a low-G force firing pin is arranged relatively near to the second end. A detonator is arranged between the high-G force firing pin and the first end. When a G-force within a first range of magnitudes is applied to the casing along its longitudinal axis, the low-G force firing pin is displaced to strike a portion of the high-G force firing pin, and if a G-force within a second range of magnitudes is applied to the casing along its longitudinal axis, the high-G force firing pin is displaced to strike the detonator. The device may become ARMED in response to a centrifugal force generated by spinning the casing on its longitudinal axis.
