Abstract
Abstract The present invention presents a movable sky light assembly used on a opening of a roof comprising a fixed frame, a wing frame with a lighting member supported on the fixed frame, said fixed frame being equipped with a driving device to operate said wing frame capable of opening and closing by connecting members for the frames. The fixed frame is provided with a detecting device for rainfall and the detecting device comprises a detecting sensor and its protecting means, and the sky light is constructed so as, when the wing frame is open, the detecting sensor of the detecting device is in the working posture and, when the wing frame is closed, the detecting sensor is protected by the protecting means. As the sky light is used also for ventilation, the connecting members of the frames are formed as a operating member of the wing frame and various aspects of the rain detecting device to close the wing frame in the rain is disclosed in relation to the operating member. Also in the invention, the fixing construction of the lighting member on the wing frame as well as the means for stable operation is improved in many ways to eliminate drawbacks of prior art through the actual experiences obtained. Various combinations are available for the product of the sky light including device for eventual manual operations.
