ABSTRACT:
The invention relates to an expandable tarpaulin comprising plastic or canvas materials, an X-pattern array of elasticized reinforcing and tie down straps or cords, and one or more elasticized perimeter cords. A problem with previous tarpaulins is that they are difficult to tie down over varying irregular sized loads. As a result, loose edges of tarp material flap in the wind causing distracting noise and damage to the vehicle, the load and the tarpaulin. Also the loose ends permit a wind tunnel effect which induces suction, loss of particulate loads causing road hazards. These problems are avoided by means of an expandable tarpaulin according to the invention which is characterized by a unitary expandable tarpaulin with elasticized reinforcing, tie downs, and perimeter hand holds, cord or straps. A safety reflective coating on selected portions of the tarp sheet may also be employed.
