CONNECTED STRUCTURE OF TRIPLE SLIDING DOOR

PURPOSE: To make a wide opening part obtainable without shutting the finger hanging part of a sliding door on an operation side by connectedly sliding a sliding door on a middle side through the connection part of the sliding door on the operation side. CONSTITUTION: In the connected structure of a triple sliding door composed by overlappedly slidably accommodating three sheets of sliding doors composed of right and left stiles and a vertical frame in a frame body attached to the opening part C of a building, either of the sliding doors except the central one of three sheets of sliding doors is set up as the sliding door 6A on an operation side, and a finger hanging part 22 is provided on the inner and outer sides of either of right and left stiles of the sliding door 6A. A connection part 20 is formed on the inside face of the sliding door 6A on the operation side, and the connection part 20 makes a sliding door 6B on a central side slide with the slide of the sliding door 6A on the operation side as it makes the finger hanging part 22 position nearer an entrance D than the sliding door 6B on the central side. The longitudinal width of the sliding door on the central side is set up shorter than that of the sliding door 6A on the operation side.
