Convertible tonneau cover

A method of using a truck bed cover comprising:

• providing the truck bed cover, wherein the truck bed cover includes:
• a top panel;
• a plurality of side panels connected to the top panel, each of the side panels including a connection portion having a slot;
• a track system, the track system including a track disposed on a bottom surface of the top panel;
• and
• a rear panel slidably disposed within the top panel,
• wherein:
• the top panel and the plurality of side panels are configured to move between a collapsed tonneau configuration and an extended cap configuration,
• the rear panel is configured to slide out from the top panel and rotate down from the top panel to form the rear panel of the truck bed cover in the extended cap configuration,
• each connection portion is curved in shape and configured to be slidably disposed in the track of the track system, and
• the track system is configured for moving the truck bed cover between the collapsed tonneau configuration and the extended cap configuration, each connection portion configured to slide along the track causing each side panel of the plurality of side panels to move outward from a center of the truck bed cover from the collapsed tonneau configuration to the extended cap configuration and to reversibly slide along the track causing each side panel of the plurality of side panels to move inward toward the center of the truck bed cover from the extended cap configuration to the collapsed tonneau configuration;
• placing the truck bed cover on a truck bed in a first collapsed tonneau configuration;
• converting the truck bed cover from the first collapsed tonneau cover configuration to a second extended cap configuration;
• slidably removing the rear panel from the top panel of the truck bed;
• and
• rotating the rear panel down from the top panel to form the rear panel adjacent to the plurality of side panels of the truck bed cover.

A truck bed cover for a truck bed, comprising:

• a top panel;
• a plurality of side panels connected to the top panel, each of the side panels including a connection portion having a slot disposed adjacent a free edge and a side panel locking portion disposed on an end adjacent to the truck bed;
• a track system, the track system including a track disposed on a bottom surface and along a length of the top panel;
• a rear panel slidably disposed within the top panel and including a window and a rear panel locking portion configured to releasably lock with a side panel locking portion of at least one of the side panels to secure the rear panel;
• a front panel slidably disposed with the top panel;
• wherein:
• the top panel and the plurality of side panels are configured to move between a collapsed tonneau configuration and an extended cap configuration,
• the rear panel is configured to slide out from the top panel and rotate down from the top panel to form the rear panel of the truck bed cover in the extended cap configuration, and
• the side panel locking portion configured to selectively secure the rear panel into place in the cap configuration,
• each connection portion is curved in shape and configured to be slidably disposed in the track of the track system, and
• the track system is configured for moving the truck bed cover between the collapsed tonneau configuration and the extended cap configuration, each connection portion configured to slide along the track causing each side panel of the plurality of side panels to move outward from a center of the truck bed cover from the collapsed tonneau configuration to the extended cap configuration and to reversibly slide along the track causing each side panel of the plurality of side panels to move inward toward the center of the truck bed cover from the extended cap configuration to the collapsed tonneau configuration.
