<p>A cover system according to one aspect of the invention includes a tarpaulin and a series of support rods attached to a longitudinal medial section thereof in spaced parallel relation and arranged to extend transversely of the truck box in the installed condition. A cable system is provided adapted to be installed such that each one of a pair of horizontal reaches of the cable extend along parallel to and above respective ones of the upper edges of the box. The support rods are adapted to be connected at their opposing ends to the respective horizontal reaches of the cable. These rods, save for a final or terminal one of the rods, are arranged to be connected to said reaches of the cable for relative movement therealong. The final rod is adapted to be connected to the tarpaulin and to said reaches of the cable so that movement of the latter can carry the tarpaulin along the upper edges of the box in either direction. The abovenoted tarpaulin also includes longitudinal marginal sections flanking the medial section and adapted to extend downwardly alongside the side walls of the box. Tensioning wire means are adapted to extend alongside the side walls of the box and means are provided for connecting the marginal sections of the tarpaulin to respective ones of the tensioning wires at spaced apart intervals for movement therealong when the tarpaulin is moved along the upper edges of the box.</p> |
