Patent ID: 8267453

Claim:
A roof ( 10 ) for use in conjunction with a pop-out ( 200 ) on a trailer ( 100 ), the trailer ( 100 ) having a body and an interior compartment ( 230 ) and the pop-out having a first sidewall ( 220 ), a second sidewall ( 230 ), an exterior rear wall ( 240 ), a floor ( 210 ) and a top opening ( 270 ), and movably extendable from a condition where it is retracted into the trailer ( 100 ) to a position where it is extended out of the trailer ( 100 ), the roof comprising: a. the roof ( 10 ) conformed to the shape of the top opening ( 270 ) of the pop-out ( 200 ) and having at least an interior longitudinal edge ( 18 ); b. the interior longitudinal edge ( 18 ) of the roof ( 10 ) rotatably affixed to the top of the trailer ( 100 ) by rotatable hinge means ( 20 ); c. the roof ( 10 ) having an underside surface with at least one track member ( 70 ) and the top ( 242 ) of the exterior rear wall ( 240 ) of the pop-out ( 200 ) having a corresponding track retaining mechanism ( 30 ) so that the track retaining mechanism ( 30 ) of the pop-out ( 200 ) slides relative to the track mechanism of the roof so that as the pop-out ( 200 ) is moved from the retracted condition to the extended condition, the roof ( 10 ) rotates about its hinge means ( 20 ) and is moved to a position over the top opening ( 270 ) of the pop-out ( 200 ) by the track retaining mechanism ( 60 , 62 , 64 ) sliding relative to the track ( 70 ) on the underside of the roof ( 10 ) until the roof ( 10 ) is in the fully extended condition over the pop-out ( 200 ), the combination track ( 70 ) and track retaining mechanism ( 60 , 62 , 64 ) serving to retain the roof ( 10 ) in its fully extended condition over the pop-out ( 200 ), and when the pop-out ( 200 ) is returned to its fully retracted position within the trailer ( 100 ), the combination track ( 70 ) and track retaining mechanism ( 60 , 62 , 64 ) enables the roof ( 10 ) to rotate in the opposite direction and rest over the exterior rear wall ( 240 ) of the retracted pop-out ( 200 ); and d. the at least one track mechanism on the underside of the roof ( 10 ) comprises an interior horizontal wall ( 72 ) on the underside of the roof ( 10 ), a first transverse sidewall ( 74 ) with an interiorly extending lower wall ( 73 ), a parallel oppositely disposed second transverse sidewall ( 76 ) with an interiorly extending lower wall ( 77 ) all of which surround a gap ( 78 ), and the track retaining mechanism on the pop-out ( 200 ) having a vertical tooth member ( 60 ) having spaced apart flanges ( 62 , 64 ), the flanges ( 62 , 64 ) respectively retained in a transverse sidewall ( 74 , 76 ) and lower interior extending wall ( 73 , 77 ) within the gap ( 78 ).
