ABSTRACT:
A shock absorbent structure for use in the wall construction of carrying cases to prevent damage to the contents within a carrying case from shock impacts. The shock absorbent structure includes a central impact shield formed of a rigid, impact resistant thermoplastic material having an interior corrugated core extending between and connecting to opposite upper and lower layers. The impact shield is sandwiched between a pair of impact pads formed of a high impact foam material adapted to absorb a substantial shock impact exerted thereon. The foam impact pads with the impact shield sandwiched therebetween are adapted to be fitted within the wall construction of a carrying case between the outer shell and inner lining whereby a shock delivered to the outer shell of the carrying case will be substantially absorbed by the impact pad with any excessive shock being elastically dispersed throughout the interior core of the impact shield in a direction substantially parallel to the wall of the carrying case.
