In this way, it is easy to incorporate this door device into the furniture main body member 5. Next, the operation of the door device of this embodiment will be explained.

To open the door body 3 in the open state, first slide the door body 3 forward. That is, when you pull the door body 3 forward,
A front and rear movable rail 23 slides forward with respect to a front and rear fixed rail 22 of the front and rear slider 21, and this front and rear movable rail 2
31 connection plate 6 to the left and right slider 41 provided on the front side of 3
The door body 3 connected via G moves forward.

When the front and back slider 21 operates as described above, the movement of the front and rear movable rail 23 is smooth due to the rollers 24 and 25 provided on each rail 22 and 23.

Furthermore, the movement of both longitudinally movable rails 23 located on both sides of the furniture main body member 5 is synchronized by the left-right synchronization mechanism 31.

That is, only the suspension of both longitudinally movable rails 23 corresponding to the moving machine is rotated by the rotation of both arm bodies 36 that are respectively engaged with these longitudinally movable rails 23 and connected and fixed by shafts 34. movements are synchronized. Of course, the shaft 34 cannot move back and forth with respect to the furniture body 1, and the arm body 3 is engaged with the notch 31 of the guide plate 38 fixed to the back and forth movable rail 23.
It is necessary that the engagement shaft 35 of No. 6 does not move back and forth with respect to the back and forth movable rail 23. As described above, since the movements of both front and back movable rails 23 are synchronized, when the door body 3 is moved back and forth, the door body 3 does not tilt in the left-right direction.
That action will be sufficient.

In addition, when sliding the door body 3 forward, both roller holders 51.5 fixed to the front side of the left and right slider 41
A position regulating roller 57 and a guide roller 58 provided on the holder plate 2 slide along both the holder plates 13 and serve as guides in the front and rear directions.

Further, as the longitudinally movable rail 23 moves forward, the vertically synchronized arm body 73, which is engaged with the engagement plate 12 provided on the longitudinally movable rail 23, moves its shaft receiving portion 73b.
This shaft receiving portion 73
A vertically synchronized shaft 74 fixed to b rotates. As this shaft 74 rotates, this shaft 7
4 to which the supported portion 76a is fixed, the rear arm body 16 rotates, and accordingly, the back and forth moving plate 78 connected to this rear arm body 76 moves by T equal to the amount of movement of the back and forth movable rail 23. move forward. Therefore, the movement of the lower part and the upper part of the door body 3 is synchronized by the touch of the vertical synchronization mechanism 71, so that the door body 3 does not tilt in the front-rear direction.

Further, when the door body 3 is pulled out forward, the support rollers 55 and 56 provided on the front sides of the left and right sliders 41 are positioned slightly floating above the support rail 62. Therefore, in this state as well as the closed state of the door body 3, the load of the door body 3 is supported by the left and right sliders 41 in the folded state and the upper support roller 80 of the vertical synchronization mechanism 71.

Next, the door body 3 is slid to the left by the left and right slider 41, and this door body 3 is overlapped with the front side of the other door body 4, and the front frontage part 2 of the furniture main body member 5 is opened. That is, the left and right fixed rails 42 fixed to the front and rear movable rails 23
Against, inside! 1Ill left and right movable rail 44 and 9 bodies 3
The door body 3 is slid to the left by sliding the outer left and right movable rails 43 that are engaged with each other.

At this time, the positioning regulation roller 57 provided on the right side roller holder 51 fixed to the outer left and right movable rail 43 comes into contact with the front side of the positioning regulation rail 61 fixed to the frame rest 11, and the door The rearward movement of the body 3 is prevented. At the same time, the guide roller 58 provided on the left roller holder 52 abuts along the front surface of the rear vertical plate portion 66c of the connecting plate 66 of the adjacent door body 4, thereby preventing the adjacent door body 4 from opening. At the same time, the opened door body 3 is prevented from moving backward.

In addition, the left and right sliders 41 supporting the lower part of the door body 3 are supported only by the front and rear movable rails 23, and the front and rear movable rails 23 are supported with some play by the fixed rails 22. Therefore, when the door body 3 is slid half of its horizontal length,
The extended left and right slider 41 is slightly bent by the load of the door body 3, and the support roller 5G provided on the left side of the outer left and right movable rail 43 comes into contact with the support rail 62 provided on the adjacent furniture main body member 6. That is, at the stage when the left and right sliders 41 are extended and it is no longer desirable to apply the load of the door body 3 to the left and right sliders 41, the load of the door body 3 is supported by the support rollers 56.

Note that the movement of the door body 3 is performed by moving the horizontal plate portion 66 of the connecting plate 6G.
The stopper 68 provided at a is locked by coming into contact with the side edge of the connecting plate 6G of the adjacent door body 4.

By the way, as shown in (e) above, in the vertical tuning mechanism 71, the arm bodies 76 and 77 that connect the back and forth moving plate 78 having the upper support row 580 and the fixed plate 75 fixed to the furniture main body member 5 are Since the distance between the shaft parts 76b and 77b pivotally connected to the forward and backward moving plate 78 is smaller than the distance between the supported parts 76a and 77a pivotally connected to the fixed plate 75, the solid line in FIG. As shown in , when the door body 3 is positioned rearward, the longitudinal movement plate 18 tilts forward and to the right, and when the door body 3 is pulled out forward, the longitudinal movement plate 78 tilts forward. It will lean to the left. That is,
