By winding up or rewinding, the door roller 8 is guided up and down on the side frames 20, and the side frames 20 are simultaneously opened and closed by extension and folding in a bellows shape as shown in FIG.

At this time, the side frame 20 is provided with a fixed outer frame 21 and a movable frame 24 which is inserted into the fixed outer frame 21 by being biased inward, and in this example, the fixed outer frame 21 is Side end rails for receiving and guiding the swing door roller 10 provided at the tip of the suspension arm 9.
The movable frame 24 is provided with a pair of front and rear long fin members facing each other, and the door frame 8 of the folding door body 2 is provided by the facing surfaces. The movable frame 24 is biased inward in the fitting groove 23 so that the movable frame 24 is fitted and inserted over substantially the entire length thereof to open and close the folding door body 2. The movable frame 24 is projected and retracted from the fixed outer frame 21 in conjunction with.

That is, the projecting and retracting of the movable frame 24 is caused by the intersection guide 28 disposed between the fixed outer frame 21 and the movable frame 24 and directed in the intersection direction.
The movable frame guide portion 26 by the engaging body 29 that engages with 28, the receiving member 31 arranged inside the movable frame 24 in the front-rear direction, and the folding door body 2 protruding from the folding door body 2 for closing movement. As an interlocking operation, by providing the movable frame 24 with an inclined guide 32 that applies force in the protruding direction from the fixed outer frame 21 against the urging force of the inward urging force, which engages with the receiving member 31. is there.

In this example, the movable frame guide portions 26 are arranged in a horizontal groove shape by forming a pair facing each other in the front and rear of the fixed outer frame 21 and opening one end in each of a plurality of pairs of guide blocks 27 provided at upper and lower ends in the longitudinal direction thereof. The cross guide 28 and the movable frame 24 project from the movable frame 24 in the front-rear direction and are engaged with the cross guide 28.

In this example, the receiving member 31 is installed on the upper and lower ends in the longitudinal direction also for connecting the facing movable frames 24, and is a vertically erected pair of synthetic resin cushion material-covered erected pipes. It is composed by.
