BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiplex door body in which openings are opened and closed by moving a plurality of sliding door bodies in the same direction, and the positions of the sliding door bodies when the openings are closed are shifted in the opening and closing directions. The sliding door device, for example,
Each sliding door body can be used for a top-hanging sliding door device or the like suspended from a guide rail above these sliding door bodies.

[0002]

BACKGROUND ART Among sliding door devices for opening and closing an opening by a sliding door body, there is a multiple sliding door device. This multi-sliding sliding door device is generally applied when the width of the opening is large, and is provided with a plurality of sliding door main bodies, and the openings are opened and closed by moving these sliding door main bodies in the same direction. At the same time, the opening is closed by these sliding door bodies that are displaced in the opening / closing direction.

In such a multi-sliding type sliding door device, when one first sliding door body, which is the most closed side when the opening is closed, is moved to the open side, it becomes the next closed side. When one second sliding door main body moves to the open side in conjunction with the first sliding door main body, and when the first sliding door main body moves to the closing side, the second sliding door main body interlocks with the first sliding door main body. It is designed to move to the closed side. Conventionally, the interlocking movement of these sliding door main bodies is performed by, for example, the first sliding door main body and the second sliding door main body in the double sliding type sliding door device in which the number of sliding door main bodies is two.
In order to move the sliding door main body at a speed of 2: 1, the first sliding door main body and the second sliding door main body are connected by an interlocking device using a timing belt, a timing pulley or the like.

[0004]

According to this prior art, in order to open and close a plurality of sliding door main bodies of a multiple sliding door apparatus in conjunction with each other, an interlocking apparatus having a complicated structure assembled from a large number of parts is required. Therefore, the assembly work is troublesome, and the overall cost of the multi-sliding sliding door device may increase.

An object of the present invention is to provide a multi-sliding type sliding door device capable of interlocking a plurality of sliding door bodies with a relatively simple structure.

[0006]

A multiple sliding door device according to the present invention comprises a plurality of sliding door main bodies, and the openings are opened and closed by moving the sliding door main bodies in the same direction. In the multiple sliding door device that closes the opening with the plurality of sliding door bodies, at least one first sliding door body that is the most closed side when the opening is closed is excluded from the plurality of sliding door bodies. A biasing unit that biases one second sliding door body toward the opening side, and the first sliding door body and the second sliding door body are connected to each other when the first sliding door body is moved to the closing side. And a connecting means for moving the second sliding door body to the closing side by moving the body to the closing side.

According to this multiple sliding door device, when the first sliding door body is moved to the opening side, the second sliding door body is urged to the opening side by the urging means, so that the second sliding door body is also opened. And the first sliding door body and the second sliding door body move together. Further, when the first sliding door body moves to the closing side, the first sliding door body and the second sliding door body are connected by the connecting means with respect to the movement in this direction, so the second sliding door body also moves closed.
The first sliding door body and the second sliding door body move together.

The biasing means in this multi-sliding sliding door device need only urge the second sliding door body toward the open side, and the connecting means moves when the first sliding door body moves toward the closing side. Since it is only necessary to connect the first sliding door body and the second sliding door body, the means for moving the first sliding door body and the second sliding door body in conjunction with both the opening side and the closing side is relatively simple. It can be of construction.

In the above, the urging means for urging the second sliding door body toward the opening side may be based on any principle. An example thereof is that when the second sliding door body is guided by a guide member to open and close, the guide member is tilted downward to the opening side, and the downward inclination of the guide member causes the second sliding door body to move. It is to always urge the opening side.

In this case, the guide member may be a guide rail, a sliding rail or the like.

Another example of the urging means is a driving device having a driving force for moving the second sliding door body to the opening side. This drive device is, for example, a device including an elastic member made of a spiral spring, a coil spring, rubber or the like in one of a second sliding door body and an immovable member that is immovable with respect to the second sliding door body. While the main body is attached, a cord-shaped member such as a wire or a belt is installed between the device main body and the other side, and the second sliding door main body is attached to the opening side by the elastic force of the elastic member acting on the cord-shaped member. It may be a vibrant thing. In addition, the drive device includes a second sliding door body and a second sliding door body.

The sliding door body may be biased toward the opening side. Further, in this drive device, electromagnets that attract or repel each other are attached to the second sliding door body and the immovable member that is immovable with respect to the second sliding door body, and the attraction force or repulsive force of these electromagnets is applied. A linear motor type that uses the second sliding door body to urge the second sliding door body toward the opening side, or an electric drive type that uses the driving force of the electric motor to urge the second sliding door body toward the opening side may be used.

Further, the connecting means for connecting the first sliding door body and the second sliding door body when the first sliding door body is moved to the closing side may be arbitrary, and one example thereof is the first sliding door body. And one of the second sliding door main bodies is provided with a connecting member that contacts the other sliding door main bodies when the first sliding door main body moves to the closing side and connects the sliding door main bodies. Another example is that both the first sliding door body and the second sliding door body
This is to provide a connecting member that abuts each other when the first sliding door body moves to the closing side and connects the sliding door bodies. Further, another example is to provide a connecting member for constantly connecting the first sliding door body and the second sliding door body so as not to interfere with the opening and closing operations thereof.

In the multi-sliding sliding door device according to the present invention described above, the movement of the first sliding door body toward the closing side is different from the biasing means for biasing the second sliding door body toward the opening side. It may be done by means of force or artificially.

In the former case, the biasing means for biasing the first sliding door body toward the closing side is provided in the multiple sliding door device, and the biasing force of this biasing means causes the second sliding door body to move. It is preferable to make it larger than the biasing force of the biasing means for biasing to the opening side.
