Abstract
A truck cargo bed utility box blow molded of high density polyethylene which complements the styling of many truck bedliners. The utility box incorporates a mounting system for a central pneumatic spring which holds the lid of the box open. The mounting system consists of a bracket mounted to a wall forming part of the storage bin and a bracket on the bin lid. The lid bracket and the bin bracket extend to and engage with a hinge pin which joins the lid to the storage bin. The brackets are constructed of sheet metal and are mechanically joined by the hinge pin. The loads imposed on the lid and bin wall by the air spring are distributed through the hinge pin. The bin bracket is also attached to a metal rim which surrounds the opening into the box to provide load distribution. The metal rim provides a distortion resistant structure to which locking hasps can reliably latch. By distributing the loads imposed on the plastic lid and plastic bin distortion of the plastic is prevented.
