Patent ID: 8061272

Claim:
A command to arm device, comprising: a hollow housing having a rounded leading end, an open trailing end, and a longitudinal axis of symmetry; a cylindrical upper housing disposed within said hollow main housing in concentric relation to said longitudinal axis of symmetry; said cylindrical upper housing having an open top and an open bottom; a lower housing disposed within said hollow main housing in concentric relation to said longitudinal axis of symmetry and having a flat bottom wall and a cylindrical sidewall mounted about the periphery of said flat bottom wall, projecting upwardly therefrom in supporting relation to said cylindrical upper housing; a centrally bored flywheel rotatably mounted about an axis of rotation, said axis of rotation being concentric with said longitudinal axis of symmetry; said flywheel having a center of gravity concentric with its axis of rotation; a timing post depending from said flywheel into said lower housing in eccentric relation to said longitudinal axis of symmetry; an actuator dome having a central aperture formed therein and having a peripheral edge that engages said upper housing; a firing pin slideably received in said central aperture of said actuator dome and in said central bore of said flywheel in coincidence with said longitudinal axis of symmetry; a zip rotor rotatably mounted about an axis of rotation, said zip rotor positioned atop said bottom wall of said lower housing; said zip rotor having a center of gravity eccentric to its axis of rotation; a detonator mounted in said zip rotor; said zip rotor having a first, unrotated position of repose where said detonator is misaligned with said firing pin; a first spring for preventing said flywheel from rotating when centrifugal forces acting on said first spring are below a preselected threshold; and a second spring for holding said zip rotor in said first, unrotated position of repose; said first spring having a first end permanently secured to a cylindrical sidewall of said upper housing; said first spring having a second end releasably secured to said flywheel; said first spring being biased radially inwardly; said bias of said first spring being overcome when centrifugal forces acting on said first spring exceed said predetermined threshold; and said flywheel being free to rotate about said firing pin when said bias of said first spring is overcome.
