Skylight With Manual Closing Feature

2) A system for lateral movement of a disc, comprising:

• an axle, said axle having a curved groove therein, the curved groove comprising side walls;
• the curved groove comprising a proximal end a distal end;
• the distal end of the curved groove comprising an end wall;
• a disc having an annular edge and an inner lumen;
• the disc comprising a rider extending into the lumen;
• the disc mounted on the axle, whereby the rider inserts to the curved groove;
• the disc rotatable in a first direction and a second direction;
• whereby, when said disc rotates in the first direction, the rider travels from a proximal end of the curved groove to a distal end of the curved groove, thereby moving the disc laterally in space.

3) A control unit for manually controlling opening and closing of a hinged panel, said control unit comprising:

• a first axle;
• a pulley wheel having a chain wrapped around a segment thereof mounted on said first axle;
• a first sprocket wheel mechanically linked to said pulley wheel;
• a second axle;
• a second sprocket wheel and a third sprocket wheel mounted on said second axle;
• a cable reel mounted on said second axle;
• a cable extending from said cable reel, a section of said cable being in contact with said hinged panel;
• a chain engaged with said first sprocket wheel and said second sprocket wheel;
• said second sprocket wheel being rotatable about an axis thereof, said second sprocket wheel being movable in a first lateral plane and a second lateral plane;
• said pulley wheel being mechanically linked to said first sprocket wheel to rotate said first sprocket wheel in a first direction, whereby when said sprocket wheel is rotated in said first direction, said first sprocket wheel rotates said second sprocket wheel is said first direction, whereby when said second sprocket wheel rotates in said first direction, said second sprocket wheel contacts said cable reel and rotates said cable reel in a first direction, and when said pulley wheel is rotated in a second direction, said second sprocket rotates about an axis thereof in said second direction and also move laterally, whereby lateral movement of said second sprocket reel causes said hinged panel to open through a series of mechanical linkages.
