In FIG. 6, 41 is a top plate of the furniture main body 1, FIGS. 3 to 5 are 42, an adjuster of the furniture main body 1, 43 is a bottom plate of the furniture main body 1, and 44 is a height adjustment in FIG. Parts for
Reference numeral 45 is a height adjusting nut, which is attached by utilizing a gap provided at the lower end of the sliding door 2. Further, a groove for a driver, a hole for a hexagonal range, or the like is provided at the lower end of the height adjusting member 44, and a hole for inserting a tool such as the driver or the hexagonal range is provided at the lower end of the sliding door 2. Has been drilled.

To open the sliding door 2, first pull the sliding door 2 forward by the pull tab 2 ', and the lower movable frame 12 is moved via the rails 13 to which the inner sliding door rollers 35 and 35' and the sliding door guide 36 fit. The child 14 moves forward, and at the same time, the upper movable frame 16 also moves forward by interlocking with the lower movable frame 12 via the connecting shaft 21 and the upper and lower arms 22 and 23, and the sliding door 2 is pulled out forward, respectively. Stop at the front position restricted by the locking devices 26, 20 '; 27, 15'. At that time, the connecting rod 29 of the lower holding device 28 and the arm 23 are reversed to the front, and the lower movable frame 12 is pressed and held at the front stop position by the spring 32. At the front stop position, the outer sliding door trochanter 37 of the sliding door 2 is positioned directly above the sliding door opening / closing fixed rail 10 (FIG. 3, FIG. 4, FIG. 6, FIG. 8).
See figure).

If the sliding door 2 is pulled to the left at this front stop position, the sliding door 2 is first guided by the end guide trochanter 49 fitted to the movable frame rail 13 at the front end of the lower movable frame 12, and at the same time the inner sliding door trochanter 3
5,35 'and the sliding door guide 36 hold it to the left, but as described above, one end of the movable frame rail 13 is provided with an inclined prevention member 13' for preventing rattling at both ends of the bottom surface thereof. In addition, since the left end of the movable frame rail 13 is inclined downward, the sliding door 2 is lowered at this portion, and the outside sliding door trochanter
37 rides on the fixed rail 10 and thereafter the sliding door 2 is the outside sliding door trochanter
It is held at 37 and moves to the left, and the sliding door 2 is opened in a sliding manner in front of the adjacent sliding door 3. In the meantime, in the upper part, the sliding door 2 is guided by the upper movable frame guide 18 of the upper movable frame 16 to move the rail 39 of the sliding door 2, and the sliding door guide of the sliding door 2.
Since 40 moves in the movable frame rail 17 of the upper movable frame 16 and is held and moved at two locations, the upper movable frame guide 18 of the upper movable frame 16 and the sliding door guide 40 of the sliding door 2, Twist,
It prevents fluttering, etc., and allows a smooth straight line.
At this time, the movable frame rail 17 of the upper movable frame or the end of the rail 39 of the sliding door 2 serves as a stopper when the sliding door 2 is opened.

When closing the sliding door 2, the sliding door 2
If you go to the right, the sliding door trochanter 35,3
5 ′ and sliding door guides 36, 40 are movable frame rails 13 of the lower movable frame 12.
Since the outer sliding door trochanter 37 is separated from the fixed rail 10 of the furniture body 1, the sliding door 2 is moved to the end by the inner sliding door trochanters 35 and 35 'and the sliding door guides 36 and 40. When the sliding door 2 is pushed into the furniture main body 1 at the end, the upper and lower movable frames 16 and 12 move backward, and the connecting rod 29 of the holding device 28 reverses backward to cause the upper and lower locking devices 26. , 20 '; 27,1
Since the upper and lower movable frames 16 and 12 are pressed to the rear stop position regulated by 5 ', the sliding door 2 is closed flush with the adjacent sliding door 3 and held at that position.

Even when the sliding door 2 is moving to the right, the movable frame rail 17 of the upper movable frame or the end of the rail 39 above the sliding door 2 may be used as a stopper, or the end of the movable frame rail 13 of the lower movable frame may be used as a stopper. Alternatively, a stopper may be provided separately. Also, until the movable frame moves to the front stop position, the sliding door 2
In order to suppress the leftward movement of the sliding door 2, if necessary, for example, a locking piece projecting forward from the lower or upper fixing frame by an appropriate length is attached to the lower part of the sliding door 2 by an inwardly bent mounting plate 34 or an upper guider mounting piece. 40 'may be locked so that the lock is released when it is moved to the front stop position, or other locking device may be provided. In the figure, the left sliding door 3 can also be opened in a sliding manner in front of the sliding door 2 in the same manner as the right sliding door 2.

As described above, the present invention has a lower movable frame on the upper part of the furniture body 1.
An upper movable frame 16 that moves in the front-rear direction in conjunction with 12 is provided,
The upper movable frame guide 18 is provided at the inner end of the upper movable frame 16.
Of the sliding door 2 is movably fitted to a rail 39 provided above the sliding door 2, and a sliding door guide 40 is provided on the rear surface of the end of the sliding door 2 which is closer to the outer side. Since it is movably fitted to the rail 17 provided at the front end of the sliding door 2,
The upper part of the is held by the upper movable frame guide 18 and the sliding door guide 40 at two places, and can smoothly go straight when opening and closing in the lateral direction. Further, since the upper movable frame 16 is provided on the upper portion as described above, the interlocking device composed of the connecting shaft 21, the arms 22, 23, etc. may be provided on only one side. The partition wall 4 (see FIG. 2) can also be omitted. The interlocking device may have another structure.

[Effects of the Invention] The present invention can obtain the following effects based on the above configuration.

(1) Since the sliding door is moved back and forth and left and right, even if it is manufactured with precision, a slight vertical gap is generated, and there is variation in the joints, but this variation is eliminated and the joint width is adjusted to a constant value. However, it can be easily done with a screwdriver or a single tool such as a hexagon range.

(2) When moving over the guide rail for holding the sliding door against the forward / backward movement of the sliding door, it is possible to smoothly move by not hitting the rail.

(3) When pulling out the sliding door, it is possible to eliminate that the side opposite to the pull tab remains by changing the mounting direction of the spring.

(4) The sliding door trochanter can be rolled along both inner side walls of the guide rail, so that when the sliding door slides laterally,
It is possible to prevent the sliding door from jumping.
