DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door used for a closet or a partition, and more particularly, to a folding door provided with an elevating skirt at a lower portion to improve airtightness when closed.

[0002]

2. Description of the Related Art A folding door in which a plurality of door bodies are foldably connected by hinges is used for a closet or a room partition. In this folding door, a guide rail is usually attached to an upper frame and a lower frame, and the door is opened and closed via a runner or a pivot. However, in recent years, in view of the aging society, there has been proposed a folding door in which a lower frame and a guide rail, which are obstacles thereof, are omitted and a floor surface is formed flat in order to easily pass a wheelchair. When the folding door is opened and closed, a certain gap is provided between the folding door and the floor surface so as not to contact the floor surface.

[0003]

However, if a gap is provided between the door body and the floor surface, there is a problem that light leaks or dust enters through the gap when the door is closed. Therefore, we tried to prototype a folding door that attaches a skirt to the lower end of the door body of the folding door and closes the gap. In addition, there is a problem that the opening and closing sound generated when the skirt rubs against the floor surface is noisy. Further, when there is dust on the floor surface, there is a problem that dust adheres to the skirt and conversely allows dust to enter. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a folding door in which dust does not adhere to a skirt, furthermore, no opening and closing sounds are generated, and light leakage and the like can be sufficiently prevented. And

[0004]

According to the present invention, there is provided a semiconductor device comprising:
The folding door described above includes a plurality of door bodies connected by hinges, and in a folding door that is supported and supported by a runner that can travel on a guide rail provided on an upper frame and opens and closes, at a lower portion of each of the door bodies, An elevating skirt that protrudes downward when closed and covers the gap with the floor surface is arranged.
Further, in the folding door according to the second aspect, in the folding door according to the first aspect, the lowering drive of the elevating skirt is such that the elevating skirt normally biased upward by an elastic member is connected by a hinge. This is performed by pushing a pin protruding from the contact surface of the door body when the door is closed.

In the folding door according to the first and second aspects, an elevating skirt is provided at a lower portion of the plurality of door bodies connected by hinges and protrudes downward when closed to cover a gap with a floor surface. Leakage and intrusion of dust can be prevented. Since the elevating skirt projects downward only when the folding door is closed, the elevating skirt does not rub against the floor surface when opening and closing. In particular, in the folding door according to the second aspect, the lifting skirt is urged upward by using an elastic member such as a spring, and the lowering drive of the lifting skirt pushes the pin protruding from the contact surface of the door body when the door is closed. Therefore, it can be operated with a simple structure without requiring power such as electricity.
