Related to the storage provided in the storage.

[0002]

2. Description of the Related Art FIG. 10 is a schematic perspective view showing an interlocking sliding door disclosed in Japanese Patent Publication No. 2505720, in which 65 is a fixed rail in which a front sliding door 61 and a rear sliding door 63 are movably suspended. Department. FIG. 11 is a partial cross-sectional view of the interlocking sliding door shown in FIG. 10, taken along line XX. FIG. 12 is a schematic perspective view schematically showing the interlocking device 60 shown in FIG. As shown in FIG. 10, a lower rail portion 53 is disposed below the fixed rail portion 65, and both ends of the fixed rail portion 65 and the lower rail portion 53 are fixed to the column members 51, 51, and the fixed rail portion 65, lower rail 53
The pillars 51, 51 form a frame. A fixed panel 64 that covers approximately one third of the right side of the opening of the frame is fixed in the frame, and a front sliding door 61 and a rear sliding door 63 that cover the left of the opening of the frame are provided. It is hung in a pull shape.

As shown in FIGS. 11 and 12, the fixed rail portion 65 has a bottom surface on one side of a hollow rectangular column-shaped member, and an opening of a predetermined width including a longitudinal center line is formed on the bottom surface of the fixed rail portion 65. The two support rails 66, which are formed at both ends and which stand at the two edge portions facing the opening on the bottom surface, respectively,
67 is integrally formed. The lower ends of plate-shaped mounting members 71 and 73 are fixed to the upper ends of the rear sliding door 63 and the front sliding door 61, respectively. Two rotating wheels 74, 74, It is fixed to the central axis of 75,75. Then, the rotating wheels 75, 75 on the rear sliding door 63 side are fixed to the panel.
A rotating wheel on the support rail 67 near 64 and the front sliding door 61 side
The front and rear sliding doors 61 and 63 suspended from the mounting members 71 and 73 by the supporting rails 66 and 67 are supported by the supporting rails 66 and 67 so as to be movable left and right.

[0004] One side of a moving force transmitting member 77 formed by shaping a rectangular plate material into an inverted L-shape in cross section is attached to the center axis of the rotating wheels 74, 74 on the front sliding door 61 side together with a mounting member 71 by a nut. The other side of the moving force transmitting member 77 is abutted on at least one of the rotating wheels 75 provided on the rear sliding door 63.

The rotating wheels 74, 74, 75, 75, and 74 of the fixed rail portion 65, the moving force transmitting member 77, the front sliding door 61 and the rear sliding door 63.
In the interlocking sliding door provided with the interlocking device 60 provided with the sliding door 75, when a moving force to the left and right is applied to the front sliding door 61, the rotating wheels 74, 74 on the front sliding door 61 roll on the support rail 66, and the front sliding door The lower end of 61 is guided by the lower rail 53 (see FIG. 10), and the front sliding door 61 moves left and right. The moving force transmitting member 77 moves with the movement of the front sliding door 61, and the rotating wheel on the rear sliding door 63 side.
The sliding doors 75 and 75 are rolled in the same direction as the moving direction of the front sliding door 61 by the amount of movement of the central axes of the two rotating wheels 75 and 75, that is, the front sliding door 61
The sliding door 63 is moved by approximately half of the moving amount of the sliding door 63. Accordingly, when the front sliding door 61 is moved in the opening direction, the rear sliding door 63 moves in the moving direction of the front sliding door 61 by approximately half of the moving amount of the front sliding door 61 in conjunction therewith, and the fixed panel 64, the rear sliding door 63 and the front sliding door 61 overlap to be in a fully opened state. In this state, when the front sliding door 61 is moved in the closing direction, the rear sliding door 63 moves in the moving direction of the front sliding door 61 by approximately half the moving amount of the front sliding door 61 in conjunction with the movement, and the front sliding door 61 The sliding door 63 and the fixed panel 64 close the entrance in a stepped manner.

[0006]

However, in the conventional interlocking sliding door, a moving force transmitting member 77 formed in an inverted L-shape is brought into contact with rotating wheels 75 provided on the rear sliding door 63 to move the sliding door. Since the rotating wheels 75, 75 are rolled by the frictional force between the force transmitting member 77 and the rotating wheels 75, 75,
In addition to the weight of the rear sliding door 63, an appropriate load is applied by the front sliding door 61 from the moving force transmitting member 77 to prevent the sliding between the moving force transmitting member 77 and the rotating wheels 75, 75. Therefore, the rotating wheels 75, 75 must use a material having high mechanical strength such as reinforced plastic so as to withstand a large load. However, such a material has a low coefficient of friction, and when an excessive moving force is applied to the front sliding door 61, there is a problem that the sliding occurs and the rear sliding door 63 does not interlock.

In order to solve such a problem, the moving force transmitting member 77 and the rotating wheels 75, 75 on the side of the rear sliding door 63 are mounted on a rack.
It is conceivable to use a pinion structure, but even with such a structure, a large load is applied to the rack and pinion, so that a slight vibration occurs at the meshing portion, and the front sliding door 61 and the rear sliding door 63 are smoothly moved. In addition, there is a problem that the rack and pinion are hardly moved, and the service life of the interlocking device is short.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a transmission member fixed to one of two adjacent sliding doors and an auxiliary member provided on the other sliding door. By making it a configuration that comes into contact with the rotating wheel,
Sliding door interlocking device that enables the use of a material having low mechanical strength and a high coefficient of friction and that can move the sliding door smoothly even with a rack and pinion structure and has a long service life, and a storage provided with the interlocking device Is to provide.
