Shock energy absorber
A shock absorber includes damping material in a solid state and which transitions from a solid to a viscous fluid state when stressed and a plunger device including a depending blade positioned in or adjacent the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing the impact.
1 . A shock absorber comprising:
damping material in a solid state and which transitions from a solid to a viscous fluid state when stressed in compression; and
a plunger device including a depending blade positioned in or adjacent the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing impact energy.
2 . The shock absorber of claim 1 in which the plunger further includes a plurality of concentric depending blades.
3 . The shock absorber of claim 2 in which the plunger includes a face plate and the concentric blades depend from the face plate.
4 . The shock absorber of claim 2 in which the blades are round.
5 . The shock absorber of claim 1 further including a rail containing the damping material.
6 . The shock absorber of claim 5 in which the plunger is configured as a beam with a linear blade depending from a top plate.

8 . The shock absorber of claim 7 in which the plunger device includes an inner cylinder having a wall terminating in said depending blade.
9 . The shock absorber of claim 8 in which said inner cylinder wall is also lined with said damping material.
10 . The shock absorber of claim 9 further including an end cap plunger with a depending blade in or adjacent damping material lining said inner cylinder wall.
11 . The shock absorber of claim 10 further including a damping material confinement wall depending from said end cap.
12 . The shock absorber of claim 11 further including a strut depending from the end cap inside the innermost confinement wall.
13 . A shock absorbing structure comprising:
a platform including damping material in a solid state which transitions from the solid state to a viscous fluid state when stressed under compression; and
a plunger including:
a face plate, and
concentric blades depending from the face plate in or adjacent the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing the impact.
14 . The shock absorbent structure of claim 13 in which the platform includes a drop platform.
15 . The shock absorbent structure of claim 13 in which the platform includes a blast shield securable to the under side of a vehicle.
16 . A drop platform comprising:
a bottom surface;
damping material in a solid state and which transitions from a solid state to a viscous fluid state when stressed under compression on said bottom surface;
a plunger including:
a face plate, and
concentric blades depending from the face plate in or adjacent the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing the impact; and
one or more side rails including:
damping material in a solid state and which transitions from a solid state to a viscous fluid state when stressed, and
a plunger configured a beam with a blade depending therefrom adjacent to or in the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing the impact.
17 . A shock absorber comprising:
an outer cylinder wall lined with damping material in a solid state and which transitions from the solid state to a viscous fluid state when stressed in compression; and
a plunger device including an inner cylinder having a wall terminating in a depending blade position in or adjacent the damping material to be driven into the damping material when impacted transitioning the damping material to a viscous fluid state absorbing the impact.

22 . The shock absorbing method comprising:
positioning a plunger device including a depending blade in or adjacent damping material in a solid state but which transitions from the solid state to a viscous fluid state when stressed; and
upon an impact, driving the depending blade into the damping material transitioning the damping material to a viscous fluid state to absorb the energy of the impact.
