In a fourth embodiment, each opening mechanism includes an actuator telescoping arm which opens a cover door by extending the telescoping arm to a desired position up to at least 180° from the closed position. To close the cover door, the opening mechanism retracts the telescoping arm to close the cover door. To provide a seal between the opposed edges of the doors, the doors can include overlapping edges with a seal along the edge of one or both doors. To open the door with its edge beneath the edge of the other door, it is necessary to partially open the overlapping door edge far enough to allow freedom of movement of the other door.

In a fifth embodiment, the cover doors are pivotally mounted on tops of the sidewalls of the truck bed by hinge assemblies. In a preferred embodiment, heavy duty hinges are located along the outside edges of each door. For example, the hinges can be weld-on barrel hinges which are welded to the tops of the truck sidewalls and undersides of the doors. In an embodiment, three weld-on hinges are located on the edge of each cover door. Alternatively, each hinge assembly can include an upper plate with a hinge connection on an upper surface of the upper plate, a plurality of through holes extending between the upper surface and a lower surface of the upper plate, a lower plate having through holes aligned with the holes in the upper plate, fasteners extending through the holes in the upper plate and the lower plate and passing through factory rail anchor points in the truck bed, and a rubber bushing around each fastener and clamped between the lower plate and an underside of the truck bed top wall of the driver sidewall or passenger sidewall. The hinge assemblies can be a full length hinge assemblies which extend the entire length of the cover doors.

In a sixth embodiment, the opening mechanism includes microswitches which are remotely controlled to open and close each cover door.

In a seventh embodiment, the telescoping arms are mounted so as to be horizontal when the cover doors are closed and rotate to an angle less that 30° when the cover doors are opened to the 180° position or beyond 180° to 210°.

In an eighth embodiment, the cover doors can include various features to provide functionality such as mounting equipment on the inside or outside of the cover doors and/or storage space inside the cover doors. For example, the cover doors can include a pattern of pre-drilled and plugged holes which can be later opened to attach mounting brackets to support electrical equipment such as spotlights, infrared or LED light fixtures, cameras, flat panel TV screens, or the like, hardware such as tools, weapons, recreational gear including bicycles, motorcycles, ATVs, firefighting, search and rescue equipment, or the like, or even signage such as posters, panels, digital displays or the like. For military or police use, the cover doors can be covered with ballistic protection such as five ply level-four KEVLAR matting. The insides of the cover doors can be hollow to store equipment such as ladders, fishing poles, tent equipment, or the like.

In a ninth embodiment, the cover doors can be adapted for human transport by incorporating a transport basket for injured patients or military personnel.
