Convertible load cover for trucks and trailers

A cover system for a bed of a truck or trailer which is convertible between a covered condition wherein a load supported upon the bed is covered to prevent or reduce weather or other damage to the load, and a retracted condition wherein the bed of the truck or trailer is open along substantial portions of its length to allow convenient loading and unloading, comprising:

• a first framework connected to the bed, said first framework being positioned at a first framework position along the bed;
• a second framework connected to the bed, said second framework being positioned at a second framework position along the bed which is spaced from the first framework position;
• a flexible cover for covering the bed approximately between the first framework and the second framework:
• a first cover tension frame connected to the flexible cover at a first tension frame connection;
• a second cover tension frame connected to the flexible cover at a second tension frame connection;
• at least one cover tensioner for tensioning the flexible cover to help support the flexible cover between the first and second frameworks;
• at least one cover suspension member which can be selectively extended along the bed to help support the cover.

• wherein at least one of the frameworks includes:
• at least one brace which is detachably mounted to portions of the bed to allow disconnection of at least portions of the frameworks during loading or unloading;
• at least one pivot connection between the at least one of the frameworks which allows the framework to pivot into a collapsed position upon the bed.
