The guide rail 12 is provided with a forward stopper 31 and a backward stopper 32 for regulating the movement of the slider 3, and the drawbacks of the conventional example are solved by configuring it as described above. In other words, from the closed state where a plurality of sliding doors 2 are lined up in a straight line, any one of the sliding doors 2 is pulled out together with the rail body 5 toward the sliding door 2.
By moving left and right and transferring to the rail 3 in front of the adjacent rail body 5, the front opening of the storage furniture 1 can be opened so that the sliding doors 2 overlap, and the sliding door can be moved left and right from the open state where the sliding doors 2 overlap. Move sliding door 2
The front opening of the storage furniture 1 can be closed by arranging a plurality of sliding doors 2 in a straight line by transferring the sliding door 2 to the rear rail 4 and pushing the rail body 5 together with the sliding door 2 to the back. The rails can be lined up in a straight line to prevent dust from entering, and the appearance is improved.Moreover, the pitch of the rails 3 and 4 at the front and rear of the rail body 5 and the amount of movement of the rail body 5 back and forth are improved. The forward stopper 31 and the reverse stopper 32, which restrict the movement of the moving part 13 of the rail body 5, are connected to the guide rail 12 so that the movement of the moving part 13 of the rail body 5 is the same.
By providing this structure, when any sliding door 2 is pulled forward together with the rail body 5, the rail body 5 is pulled forward by the pitch of the rails 3 and 4, and when the rail body 5 is pulled out together with the sliding door 2, the rail body 5 is pulled out.
The rear rail 4 and the rail 3 in front of the adjacent rail body 5 that is not pulled out match exactly, and the sliding door 2 can be easily and reliably transferred by simply moving the sliding door 2 in the left and right direction. It is something that

Next, the operation of the storage furniture sliding door device configured as described above will be explained. The state shown in FIG. 2 is a closed state, in which the pair of sliding doors 2 are lined up in a straight line. At this time, the rail body 5 is inserted at the rear, and the arm 1
7 is also retreating. A force is applied by the tension spring 30 in the direction in which the movable part 13 moves rearward, and the backward movement stopper 32 abuts on the contact part 33. Also, at this time, the rail bodies 5 adjacent to the left and right
The front rails 3 and the rear rails 4 match in a straight line. From this state, the sliding door 2 on the right
To open it, do the following: First, pull out the sliding door 2 on the right side forward. Then, the rail body 5 and the arm 17 move forward together with the sliding door 2. At this time, the left and right moving parts 13 are interlocked by a pair of left and right interlocking links 22, so no matter which part of the sliding door 2 in the left and right direction is held and pulled, the sliding door 2 is synchronously moved by the left and right interlocking links 22 and the sliding door 2 is parallel. It is pulled out smoothly. In other words, when a force in the pulling direction is applied to one moving part 13, it acts as a force to rotate the pair of left and right interlocking links 22 about the shaft 23, and a pulling force also acts on the other moving part 13. Also at this time, the slide portion 26
moves backward along the slide rail 27, and when the pair of left and right interlocking links 22 go beyond a straight line, the pair of left and right interlocking links 22 are reversed by the tension spring 30, and the tension spring 30 A force is applied in the direction in which the moving part 13 moves forward. Then, the forward stopper 31 moves until it hits the moving metal fitting 21 and stops, and the rail body 5 moves to a predetermined position in front. Furthermore, a pair of vertical interlocking links 34
Since the arm 17 and the moving part 13 are interlocked, no matter which position in the vertical direction of the sliding door 2 is held and pulled, the sliding door 2 is synchronously pulled out in parallel by the vertical interlocking link 34. That is, as with the left and right interlocking links 22 described above, when a pulling force is applied to one side, a pulling force is applied to the other side at the vertical interlocking links 34. When the sliding door 2 is pulled forward, the vertical link 34 is reversed from the state shown in FIG. 4a to the state shown in FIG. 4b, and the arm 17 projects forward in synchronization with the rail body 5. When the right sliding door 2 protrudes together with the rail body 5, the moving bracket 21 hits the forward stopper 31, and the rail 3 of the left rail body 5 and the rail 4 of the right rail body 5 are moved as shown in FIG. Matches in a straight line. When the right sliding door 2 is moved to the left in this state, the right sliding door 2 is transferred onto the rail 3 of the left rail body 5 as shown in FIG. 3, and the sliding door 2 is opened, and the outer surface of the left sliding door 2 is Sliding door 2 on the right overlaps. Also, sliding door 2 on the right side
To close the door, move the sliding door 2 on the right side to the right side. When the sliding door 2 is moved to the right side, the sliding door 2 is transferred to the rail 4 of the right rail body 5. Then, push the sliding door 2 backward in the opposite direction to the above. Then, the rail body 5 and arm 17 retract backward together with the sliding door 2. At this time as well, the left and right links 22 synchronize the left and right sides, and the vertical link 34 synchronizes the top and bottom.
Further, when the slide portion 26 moves forward along the slide rail 27 and the left and right interlocking links 22 exceed the state where they are in a straight line, it is reversed by the tension of the tension spring 30 and moves backward together with the rail body 5. The moving part 13 moves and the reverse stopper 32 hits the contact part 3.
It stops when it hits 3. Also, when opening the left sliding door 2, move the sliding door 2 to the rail body 5 or the arm 1 as described above.
7 and pull it forward to move the sliding door 2 onto the rail 3 of the right rail body 5.

Further, FIGS. 13a, b, c, and d show other embodiments of the description. In this embodiment, the inside of the storage furniture 1 is partitioned by two partition plates 10 to form three partition spaces 11, and three sliding doors 2 are connected to the storage furniture so as to correspond to each partition space 11. It is arranged in the front opening of No. 1. In this case, each partition space 11 and the sliding door 2 have the same structure as in the above embodiment, and the first
It can be opened and closed as shown by the arrows in Figures 3a, b, c, and d. Furthermore, storage furniture 1 having three or more sliding doors 2 in its front opening can be similarly formed.

[Effect of the invention] As described above, the present invention arranges a plurality of rail bodies consisting of two rails in the front and back at the lower part of the front side of the storage furniture so that they are located in the width direction of the storage furniture. The lower part of the multiple sliding doors placed on the front side of the storage furniture can run freely on the rail of the rail body, so any sliding door can be moved from the closed state where multiple sliding doors are lined up in a straight line to the rail. The front opening of the storage furniture can be opened by pulling the door forward with the body, moving the sliding door from side to side, and transferring it to the rail in front of the adjacent rail body, so that the sliding doors overlap, and the sliding door can be opened from the open state where the sliding doors overlap. By moving the sliding door from side to side and transferring it to the rear rail, and pushing the rail body together with the sliding door to the back, multiple sliding doors can be lined up in a straight line to close the front opening of storage furniture. The sliding doors can be lined up in a straight line to prevent dust from entering, and the appearance is improved.In addition, the rails are arranged so that the pitch of the front and rear rails of the rail body and the amount of movement of the rail body are the same. Since the guide rail is provided with a forward stopper and a backward stopper that restrict the movement of the moving parts of the body, when the rail body is pulled out, the rail behind the pulled out rail body and the rail in front of the rail body that is not pulled out are It aligns accurately in a straight line, and allows the sliding door to be easily and securely moved from side to side.Furthermore, when the rail body is pushed in, the rails in front of the left and right rail bodies align with each other. The rear rails can be aligned in a straight line, and the sliding doors can be arranged in an accurate straight line when the sliding doors are closed. In addition, guide rails are placed on both sides below the bottom plate of the storage furniture, and movable parts that extend rearward from both the left and right sides of the rail body are movably attached to the guide rail, so that the rail body can be moved back and forth. Like a steel desk drawer, it can be moved back and forth with the rail body floating, and the rail body can be taken in and out smoothly with almost no frictional resistance, and it has a forward stopper and a reverse stopper. are installed on the guide rail, so even if a forward stopper or reverse stopper is installed, it can be installed in a position where it cannot be seen from the outside, improving the appearance.Furthermore, the rail body, moving part, guide rail, etc. can be attached to storage furniture. Since it is provided below the bottom plate of the storage furniture, the mechanical parts such as the rail body, the moving part, and the guide rail are provided outside the storage part of the storage furniture, and the above-mentioned mechanical parts do not interfere with the loading and unloading of items into the storage part of the storage furniture. It is something.
