Abstract: A tonneau cover assembly is provided having a rail network, a plurality of clamps, one or more crossbars and a flexible top. The rail network is secured about the bed of a pick-up truck, using clamps. Thus, no holes are made in the vehicle, and the entire tonneau cover assembly can be mounted without the use of tools. After the rail network is secured to the truck, the crossbars are placed over the truck bed, and snap onto the clamps. Insert tips allow the crossbars to adjust to various lengths. A tang on the clamp is received by the insert tip, and provides resistance to torsional forces. A hook assembly is sewn about the periphery of the flexible cover and is secured to the rail network. To disengage the flexible cover from the rail network, a stripping member is used. In the first preferred embodiment, the stripping member rests within the rail network and forcibly ejects a portion of the hook assembly from the rail network.

Abstract: A unitary liner for truck beds including a flange for positioning the side wall of the liner relative to the side wall of the truck such that the bottom of the liner side wall and adjacent portions of the bottom side walls are displaced from the bed bottom wall. The bottom wall of the liner includes raised ribbed portion displaced from the side and front walls to create peripheral drains and the bottom wall is inclined relative to the side, front and bottom walls of the liner at the corners of the side and front walls to prevent water and other foreign material from collecting at the corners. A mounting device is provided which is secured to the side rail of the bed through a slot provided in the side wall of the liner to permit horizontal and vertically downward movement of the liner and prevent vertically upward movement of the liner.
