Abstract:
1. A portable convertible blast effects shield comprising: a standalone set of at least two frusto-conically-tapered telescoping rings each having a lesser diameter end and a greater diameter end and constructed from a composite fiber and matrix material substantially inhibiting blast effects from passing therethrough, said set of telescoping rings arranged so that for each adjacent pair of rings the diameter of the greater diameter end of a first ring is less than the diameter of the greater diameter end of a second ring but greater than the diameter of the lesser diameter end of the second ring, for enabling conversion of said set of telescoping rings between a telescopically-extended upright configuration having adjacent pairs of rings releasably secured to each other by friction fit so as to form an expanded inner volume, and a telescopically-collapsed configuration having adjacent pairs of rings disengaged from each other, wherein the telescopically-extended upright configuration has opposing open ends formed by innermost and outermost ones of said rings, with the open ends dimensioned to receive a suspected explosive through one of the open ends so as to surround the suspected explosive, whereby upon detonation of the explosive in the expanded inner volume, blast effects of the detonation are laterally shielded by the set of telescoping rings and directed out through said open ends.
