Abstract: A hinging structure for fixing a cover onto a pickup truck bed. Easy access to the bed is provided by the pivoting of one end of the cover upward away from the bed side walls. The structure includes an angle bracket fixed to a bed side wall and a cooperating latch member fixed to the cover and which interlocks to hold the cover onto the bed side walls while allowing one end of the cover to be pivoted upward for access to the bed. The latch includes a pivoted member that interfits with the angle bracket to hold the cover on the bed but which can be pivoted to a position to disengage the angle bracket for removal of the cover.
