The aforementioned member 14B is the same as the L-shaped member 14A in the lower part, which extends to s and is placed above. The other l-shaped members of the department are locked with it and have a long shape. The operation of the folding door A with the above mechanism is mainly described with reference to FIG. 4. Put your hand on the handle τ of the folding door A (picture丨), open it by pulling the door to the right, the moving body KK will go to the right At the same time, while moving the two doors Al and A2 with the first axis S1 as the pivot, they are folded toward each other, and close to the opening surface, and are opened to a state as large as 90 degrees as shown in FIG. 4. As shown in FIG. 4, the door A1 on the right side is opposite to the opening surface as shown in FIG. 4 at a substantially correct state of 90 degrees. Due to the constraint condition that the door A2 on the left side is connected by the rotating member 14, In the 0 degree state, the two doors Al, A2 can only be folded to the opening angle shown in Fig. 4. Moreover, the rotating member Η 'is pivoted by a small angle with the third axis S3 standing on the moving body 12 as a pivot. However 'If you want to open the door A1 from the 90-degree open state and use the second axis S2 as the pivot to open it 180 degrees, the left door A2 can follow the action of the door Al because of the existence of the rotating member 14 and can be opened to FIG. The state shown by the solid line (open state at approximately 90 degrees) is above. The better one is the paper size that can be opened.

However, in this configuration example, in order to open further from the 90-degree state, a hinge device with two pivot axes S2 and S2 "staggered from each other is used as the door A1 and the frame. The side hinge 10A is assembled with a hinge mechanism (as disclosed by the applicant in Japanese Patent Application Laid-Open No. 6-240943, which can be opened and closed in two stages). Therefore, after 90 degrees, the other axis S2 '' (located in the first The 2 axis S2 is close to the stated side A1L side of the door A1), which is the pivot. As a result, the two doors Al, A2 are folded together at approximately 180 degrees, as shown in FIG. 4 with a 2-point lock line A1 ' ', A2' '. In this case, the L-shaped member 14A and the member 14B of the rotating member 14 reach the positions of the two-point chain lines 14A '' and 14B '', respectively. That is, the length of the rotating member 14 from the position of the third axis S3 to the position of the fourth axis S4 is set to a size where the door A2 can be located at a position of approximately 180 degrees of the two-point chain line A ''. On the other hand, if only one hinge S2 hinge device is used, in order to enable & A1 to open more than 90 degrees, the aforementioned length of the rotating member 14 must be set to be larger than the embodiment of FIG. 4 Slightly shorter. The foregoing describes the advantages of using a hinge device having two pivots S2, S2, which are offset from each other. As shown by the two-point chain line in Fig. 4, if the cabinet is provided with several pieces, the door B1 "will be located in front of the frame 10" next door. In this state, if the second axis S2 is used as the pivot If the door A1 is to be opened more than 90 degrees, the door A1 will interfere with the opening of the cabinet next door Bi, which will cause interference. To prevent this interference, it is necessary to shift the pivot from the position of S2 to the door B1. ,, The thickness is equivalent to S2 "position to open.
