Panel device

A roof light for a recreational vehicle, comprising an at least substantially polygonal frame which surrounds an opening and comprising a window, which window is connected to the frame for pivoting about a pivot axis and comprises a panel which extends over the opening, wherein provided between the frame and the window is at least a stay device which is manipulable between a first position, in which the window is forced into a flat state and closes the opening, and at least one second position in which the window is raised by the stay device and leaves the opening at least partially clear, which stay device comprises a stay which extends movably from an elongate guide at a first outer end and is connected pivotally to the window at an opposite, second outer end, wherein the stay is adjustable in the guide between a first position, in which the stay lies at least substantially flat relative to the guide, and a second position in which the stay has taken on a raised state from the guide, wherein the stay is coupled to an actuator via a flexible transmission, wherein the transmission comprises at least one tension-resistant pull member which is coupled to the stay and moves the stay from one of the first and second position to another of the first and second position when the actuator is energized, and wherein the at least one pull member is introduced axially movably into an axially at least substantially rigid yet flexible sleeve, a first outer end of which is fixed to or close to the stay and a second outer end of which is attached to or close to the actuator.
