Dynamic roof top for truck body and method of operation

A method of providing a closure for a roof top for a truck body, the method comprising the steps of:

• providing at least one dynamic panel moveably supported by sub-walls coupled to first and second sidewalls that span a truck bed;
• translating the at least one dynamic panel from an extended or closed position to a retracted or opened position and from said retracted or opened position to said extended or closed position by a rail system comprising first and second rails each located on an exterior surface of the sub-walls, said first and second rails having a plurality of wheels coupled to said at least one dynamic panel, the wheels rotate along said track during translation of said dynamic panel;
• and
• providing a static panel that upon translating said at least one dynamic panel to the open or retracted position is overlapped by said at least one dynamic panel, a portion of said sub-walls coupling the static panel to said first and second sidewalls, the rail system supported at least partially by the sub-walls.

A dynamic roof top for a truck body, the dynamic roof top comprising:

• first and second dynamic panels that translate from an extended or closed position to a retracted or opened position and from said retracted or opened position to said extended or closed position;
• the translation of said dynamic panels occurring manually by an operator of said dynamic roof top;
• a static panel that is overlapped by said first and second dynamic panels, further wherein said second dynamic panel is enveloped by both the first and static panels when said first and second panels translate into the retracted or closed position;
• a rail system to allow said first and second dynamic panels to translate from said extended or closed position to the retracted or opened position and from said retracted or open position to said extended or closed position;
• and
• first and second sub-walls and said rail system comprising first and second rails coupled to outside surfaces of respective first and second sub-walls and third and fourth rails coupled to outside surfaces of respective first and second sub-walls, said first and second rails translate said first dynamic panel from said extended or closed position to the retracted or opened position and from said retracted or open position to said extended or closed position, said third and fourth rails translate said second dynamic panel from said extended or closed position to a retracted or opened position and from said retracted or open position to said extended or closed position;
• wherein said first and second rails translating said first dynamic panel operate independently of said third and fourth rails translating said second dynamic panel, and said first and second rails comprise differing lengths from said third and fourth rails based on travel distance of said first and second dynamic panels, further wherein, the first and second rails are supported at least partially on a portion of the first and second sub-walls located between the static panel and sidewalls of a truck body supporting the dynamic roof top.
