As shown in FIGS. 1 and 3, the interlocking sliding door 100 is driven by the interlocking sliding door drive device 10 to open and close in an interlocking manner.
The interlocking sliding door drive device 10 includes a drive unit 20 and a control unit 30.

The drive unit 20 is a rack that is a rack arranged in the door frame along the sliding direction of the first sliding door 110, and a pinion that is arranged on the top surface of the first sliding door 110 and that rotates the guide rail 21. And a gear 22.
Further, the drive unit 20 includes a drive gear 23 that is a bevel gear that drives the traveling gear 22, and a motor 24 that rotationally drives the drive gear 23, and is arranged on the top surface of the first sliding door 110.
The motor 24 is rotationally driven to slide the first sliding door 110 in response to a drive instruction from the control means 30. The drive instruction is transmitted by the wiring 31 between the control means 30 and the motor 24. The wiring 31 has an extra length so that the first sliding door 110 can slide from the closed state to the fully opened state.

As shown in FIG. 1, a switch 40 for instructing the degree of opening is connected to the control means 30. The switch 40 includes first to fourth switches 41 to 43 in which “1” to “3” are written corresponding to the first to third sliding doors 110 to 130.
In the present embodiment, by pressing the first switch 41 to the third switch 43, an opening instruction corresponding to the number of sliding doors from the first sliding door 110 to the third sliding door 130 is output to the control means 30. Although only the switch 40 installed in front of the interlocking sliding door 110 is illustrated in FIG. 1, the switch 40 is also provided on the other side of the interlocking sliding door 100 for a passerby traveling from the opposite direction of the passage. It is connected to the control means 30 and is omitted in FIG. 1 for convenience.

When the first switch 41 to the third switch 43 are pressed by a passerby, the control unit 30 controls the plurality of sliding doors (the first sliding door 110 to the third sliding door 130) indicated by the first switch 41 to the third switch 43. Based on the opening instruction according to the number of opened/closed sheets, a driving instruction for instructing the motor 24 of the driving means 20 to open is output.

If the passerby is a healthy person who walks while standing, the first switch 41 labeled "1" is pressed. An opening instruction indicating that one sliding door is opened by pressing the first switch 41 is input to the control unit 30.

The control means 30 outputs a drive instruction to the motor 24 (drive means 20) for the time required for the slide before the first sliding door 110 interlocks the second sliding door 120. The motor 24 that has received the drive instruction rotates in the forward direction to rotate the drive gear 23, and the drive gear 23 rotates to rotate the traveling gear 24.
As the traveling gear 24 rotates, the traveling gear 24 moves along the guide rail 21, and thus the first sliding door 110 slides in the opening direction. Then, when the first sliding door 110 slides before the second sliding door 120 is interlocked, the opening instruction from the control means 30 stops.
Therefore, the interlocking sliding door 100 stops in a state where only the first sliding door 110 of the first sliding door 110 to the third sliding door 130 is open.
Therefore, when a normal person passes through the interlocking sliding door 100 as a passerby, it is possible to open a width suitable for the normal person.

Next, if the passerby is a cared person sitting in a wheelchair, the second switch 42 labeled "2" is pressed. An opening instruction indicating that the two sliding doors are opened by pressing the second switch 42 is input to the control means 30.
The control unit 30 outputs an opening instruction to the drive unit 20 for the time required for the slide before the first sliding door 110 interlocks the second sliding door 120 and the second sliding door 120 interlocks the third sliding door 120.

When the driving unit 20 slides the first sliding door 110 to interlock the second sliding door 120 and slides before the second sliding door 120 interlocks the third sliding door 130, the opening instruction from the control unit 30 stops.
Therefore, the interlocking sliding door 100 stops in the state where the first sliding door 110 and the second sliding door 120 of the first sliding door 110 to the third sliding door 130 are open.
Therefore, when the care-receiver passes through the interlocking sliding door 100 as a passer-by on a wheelchair, a width suitable for the wheelchair can be opened.

By doing so, it is possible to safely pass through the interlocking sliding door 100 even with a wide range of delivery vehicles.

As described above, according to the interlocking sliding door drive device 10, the control unit 30 outputs the driving instruction to the driving unit 20 based on the opening instruction indicating the width of the passerby, so that the number of opened sliding doors can be designated. Therefore, the interlocking sliding door drive device 10 can easily change the opening degree of the sliding door.

The control unit 30 outputs a drive instruction for a time period corresponding to the number of opened sheets to the drive unit 20, so that the control unit 30 can determine the drive instruction based on the release instruction.
A switch corresponding to the number of opened interlocking sliding doors 100 is provided. Therefore, by pressing the switch 40 corresponding to the number of opened interlocking sliding doors 100, an opening instruction corresponding to the number of opened/closed doors can be output to the control means 30.

In the above description, the control means 30 has explained that the sliding door 101 of the interlocking sliding door 100 is opened, but if some or all of the three sliding doors 101 are opened, the control means 30 is opened after a predetermined time. It is possible to bring the interlocking sliding door 100 into the closed state by outputting a closing instruction to the driving means 20 for closing for a time period corresponding to the number of sheets.

In addition, in the first embodiment, the control unit 30 controls the number of opened sheets according to the time when the drive instruction to the motor 24 is output, but the first sliding door 110 to the third sliding door 130 are sequentially opened. A sensor may be provided at each position and the number of opened sheets may be detected by the sensor.

Further, the control means 30 opens the first sliding door 110 to the third sliding door 130 as the opening degree according to the number of opened sheets corresponding to the first switch 41 to the third switch 43 of the switch 40. However, since the control means 30 outputs a drive instruction for a time period corresponding to the opening degree to the drive means 30, for example, every 0.5 sheets or 1 is made to correspond to the first switch 41 to the third switch 43. . It is possible to control not every single sheet, such as every two sheets. In addition, 0.2 sheets for pets and ventilation, 1 sheet for healthy persons, 1.5 sheets for cared persons in a wheelchair, and so on. It is also possible to freely set the opening degree.

However, in the first embodiment, the control unit 30 outputs a drive instruction in which the opening degree corresponds to the number of opened sheets, so that the passerby changes the opening degree of the first sliding door 110 to the third sliding door 130. Since it can be recognized as the number of sheets opened, it is easy to grasp the opening.

Further, after opening a predetermined number of sliding doors 101, the control means 30 outputs a closing instruction to the driving means 20 to close for a time corresponding to the number of opened doors when a predetermined time elapses. Is closed. For example, when the control means 30 is notified that the same switch 40 is pressed (the first switch 41 for the first switch 41, the second switch 42 for the second switch 42, etc.), the open state is maintained. Alternatively, the opening time may be extended by a predetermined time. By doing so, a passerby who takes a long time to pass through the interlocking sliding door 100 and a passerby who carries a luggage can be safely passed.
