Abstract
Abstract A portable bullet-proof shield for use by law enforcement agents, is horizontally curved and of sufficient height and width to protect substantially the body of the user when the shield is being carried or is resting in a free-standing mode. The shield includes a viewing lens assembly near its top, an adjustable shoulder suspension strap, a horizontal hand grip bar, and elastic horizontal stand-off straps on its interior side to protect the body against "blunt trauma". The shield has a frontal skin formed of aluminum or high-impact plastics behind which is disposed a penetration-resistant wall consisting of multiple layers of woven synthetic fabric which may be laminated or non-laminated. A single layer of waterproof synthetic fabric or rear skin formed of high-impact plastics defines the interior face of the shield. The shield possesses a frame consisting of top, intermediate and bottom horizontal bows which are riveted to the shield primarily at opposite side rearwardly projecting portions of the shield. When the rear skin is formed of high-impact plastics, these may be integrally formed into the skin. The top and bottom edges of the shield may be capped with tough plastics material. The viewing lens assembly includes multiple thicknesses of clear penetration-resisting plastics material held in assembled relationship by front and rear lens caps secured by interfitting bolts and tubular nuts which penetrate the body of the shield, or integrally formed when the frontal and rear skins are formed of plastics.
