DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device installed at an entrance of a storeroom, a house, a warehouse or the like.

[0002]

2. Description of the Related Art Conventionally, as one form of the above-mentioned sliding door device, there is an interlocking sliding door device in which one of two sliding doors is opened and closed, and the other is also opened and closed in conjunction with the other. -23789. Such an interlocking sliding door device has a structural feature in that all the sliding doors are operated in an interlocking manner by running a towing wire between the sliding doors. However, in this interlocking sliding door device, since the pulling wire is used as the interlocking means, there is a possibility that the wire breaks or the wire comes off the pulley. In particular, when a sliding door made of a thin steel plate is used as in a storage, the door flaps when opening and closing, and the wire is likely to be detached. Therefore, the present applicant has previously proposed an interlocking sliding door device B having a configuration as shown in FIGS. 9 to 11 in Japanese Patent Application Laid-Open No. Hei 6-317067. The interlocking sliding door device B includes a left and right corner pillars 50 and 51, a fixed rail portion 52 and a lower rail portion 53, and a rectangular frame 5.
A fixed panel 55 is integrally attached to the right side of the rectangular frame 54, and a front sliding door 57 and a rear sliding door 58 are attached to the left opening 56 of the fixed panel 55 in a sliding manner. ing. As shown in FIGS. 10 and 11, a horizontal moving rail 60 is fixed to the upper surface of the front sliding door 57 via a front sliding door hanger portion 59, while the rear sliding door hanger is fixed to the upper surface of the rear sliding door 58. A rotating wheel 63 that can travel on a fixed support rail 62 provided on the fixed rail portion 52 is attached via a portion 61. The horizontal moving rail 60 is mounted on the rotating wheel 63. 10 and 11, an auxiliary wheel 64 is attached to the front sliding door hanger portion 59, and the auxiliary wheel 64 is mounted on another fixed support rail 65 provided on the fixed rail portion 52. I have. Therefore, when the front sliding door 57 is moved from the closed state to the opening direction, the horizontal moving rail 60 integrally attached to the front sliding door 57 moves integrally, and the horizontal moving rail portion 60 is placed by this movement. The rotating wheel 63 is rotated by the frictional resistance between the two, rotates on the fixed support rail 62, and also moves the sliding door 58 in the opening direction after the rotating wheel 63 is integrally attached. At this time, since the moving distance of the rear sliding door 58 is half of the moving distance of the front sliding door 57, the rear sliding door 58 and the front sliding door 57 are in the overlapping state at the end point position and are in the fully opened state.

[0003]

However, the above-mentioned interlocking sliding door device B still has the following problems to be solved. That is, the rotating wheel 63 is merely mounted on the fixed support rail 62 so as to be movable. Therefore, in a situation where the sliding doors 57 and 58 have become lighter as in recent years, if the front sliding door 57 is closed suddenly, a slip easily occurs between the rotating wheel 63 and the horizontal moving rail 60, and this slippage is caused. 12A, even if the user puts his hand on the front sliding door 57 in the fully closed state and opens it as shown in FIG.
As shown in (b), the rear sliding door 58 does not overlap with the front sliding door 57 at the end point position, and a part of the rear sliding door 58 remains and cannot be fully opened. In addition, when the rear sliding door 58 is moved to the fully closed position when the front sliding door 57 is closed with a hand from a state where the rear sliding door 58 is partially left as shown in FIG. As shown in c), the front sliding door 57 does not reach the fully closed position, and a gap G is left between the front sliding door 57 and the left corner post 50. To close this gap, the front sliding door 5 must be closed.
7 must be forcibly slipped, which causes a failure. The present invention has been made in view of such circumstances, and in an interlocking sliding door device including a plurality of sliding doors, by pulling one sliding door, the other sliding doors can be linked and fully opened, and the sliding door can be fully opened. It is an object of the present invention to provide an interlocking sliding door device that can be fully and automatically closed by releasing the sliding door.

The first rotating wheel and the second rotating wheel) move, the rear sliding door and the front sliding door overlap on the fixed panel, and the interlocking sliding door device is fully opened.

Further, the interlocking sliding door device is fully closed from the fully open state position or an arbitrary opening position by releasing the hand from the front sliding door. At this time, both the rotating wheel drive rail and the sliding door suspension support rail have an upward slope toward the opening direction, and are interposed between the first rotating wheel and the second rotating wheel. The one-way clutch can transmit the rotational force of the second rotating wheel to the first rotating wheel only when the second rotating wheel moves in the opening direction. Can rotate freely with each other.
Therefore, the first rotating wheel rolls on the fixed moving rail in the closing direction by the weight of the rear sliding door, and the rear sliding door integrally attached with the first rotating wheel also moves in the closing direction. On the other hand, the rotating wheel driving rail also rolls on the second rotating wheel that rotates independently of the rotation of the first rotating wheel in the closing direction by the weight of the front sliding door, and the second rotating wheel is integrally attached. The front sliding door also moves in the closing direction. in this way,

In the interlocking sliding door device described above, the outer peripheral portion of the second rotating wheel is formed of a rubber ring having a large coefficient of friction, and the lower surface of the rotating wheel driving rail mounted and supported on the second rotating wheel is also provided with a coefficient of friction. Since the large rubber shoe is attached, the rail for driving the rotating wheel is placed on the second rotating wheel, and when the rail for driving the rotating wheel is moved in the opening direction, slipping is caused only by the weight of the rail for driving the rotating wheel. Without the occurrence, the second rotating wheel can be surely rotated to roll on the rear sliding door suspension support rail, and the rear sliding door can be reliably moved.

In the interlocking sliding door device according to the third aspect,
A rocking amount restricting slot is provided vertically at a position spaced apart from the pivot pin of the rotating wheel drive rail, and a pin attached to the center of the upper part of the front sliding door is inserted into the rocking amount regulating slot. Therefore, it is possible to prevent the rotating wheel drive rail from swinging more than necessary, and it is possible to easily assemble the interlocking sliding door device.

In the interlocking sliding door device according to the fourth aspect,
Since the shock absorbing device absorbs the movement energy generated by the movement of the front sliding door during the closing operation, the front sliding door is closed quietly and gently.

In the interlocking sliding door device according to the fifth aspect,
Even when three or more sliding doors are movably arranged in a sliding state within the rectangular frame, the interlocking sliding door device can be completely and automatically fully closed.
