Abstract
Elastic, spider web shaped devices for restraining cargo located in the bed of a truck or trailer are disclosed. Elastic, spider web shaped, cargo restraint devices for both holding down loads and for enclosing the open tailgate area of a truck or trailer are disclosed. The spider web shaped cargo restraint devices are formed of pieces of tough, elongated, stretchable material, e.g., bungee or shock cord. The pieces include two or more generally concentric loops and a plurality of radial arms laid out in a spider web shape. The concentric loops are spaced apart and surround a center device, such as a stainless steel ring, a metal plate or a piece of rigid plastic. The inner ends of the radial arms are attached to the center device and radiate outwardly. Where the loops and arms cross, they are joined by "hog" rings, or some other suitable attachment element. Depending upon strength requirements, the outer loop may be formed of the same strength shock cord as the inner loop(s) and the radial arms, or by stronger shock cord. The outer loop is attachable to the side wall surrounding the bed of the truck or trailer or to the edges of an open tailgate area in various ways. Cleats or hoo…
