Further, a second sliding door drive sprocket 44c is provided on the side of the sliding door support 30 facing inward. The first sliding door drive sprockets 44 a and 44 b and the second sliding door drive sprocket 44 c constitute the first sprocket and are provided on the drive shaft 43 so as to transmit the rotational force of the drive shaft 43. .
[0019]
In addition, the second panel members 22a and 22a ′ have inwardly facing side surfaces at the same height as the first sliding door drive sprockets 44a and 44b, respectively, at corresponding positions separated by a predetermined distance. 45a and 45b are rotatably provided. Endless chains 46a and 46b, which are rotational force transmission members mounted between the first sliding door driving sprockets 44a and 44b and the second sprockets 45a and 45b of the first sprocket, are attached via mounting portions 47a and 47b. It is fixed to the first sliding door 21. That is, when the first sprockets 44a and 44b are rotated, the endless chains 46a and 46b are rotated, and at the same time, the attachment portions 47a and 47b are moved to move the first sliding door 21, and then the endless chains 46a and 46b are rotated. The force is transmitted to the second sprockets 45a and 45b, causing the second sprockets 45a and 45b to rotate. Further, the second sliding door of the first sprocket disposed on the side surface facing the outer side of the second panel member 22a ′ on the side surface facing the inner side of the sliding door support 30 facing the surface on which the drive motor 41 is located. A chain 48 is arranged so that the gears of the drive sprocket 44c mesh with each other. The chain 48 does not need to rotate and is fixed.
[0020]
Next, the operation of the sliding door device 1 of the present embodiment will be described. When closing the gate using the sliding door device 1 of the present embodiment, first, a switch (not shown) is pushed to activate the drive motor 41 and simultaneously connect the clutch mechanism 42 to the drive shaft 43 to drive. The shaft 43 is rotated to rotate the first sprockets 44a, 44b, 44c. Thereby, the second sliding door drive sprocket 44c of the first sprocket rotates to move the second sliding door 22 in the closing direction of the sliding door 2 (arrow direction D in FIG. 1). At the same time, the endless chains 46a and 46b are rotated by the rotation of the first sliding door driving sprockets 44a and 44b so that the mounting portions 47a and 47b, that is, the first sliding door 21 is directed in the same direction D as the second sliding door 22. Move. That is, the first sliding door 21 and the second sliding door 22 move in synchronization. At this time, the first sliding door 21 is housed between the two panel members 22 a and 22 a ′ of the second sliding door 22.
[0021]
Moreover, when opening a gate using the sliding door apparatus 1 of this embodiment, the 1st and 2nd sliding doors 21 and 22 are moved synchronously by performing the same operation from the state with the gate closed. be able to.
[0022]
Further, in the event of an emergency, the clutch mechanism 42 is operated to disconnect the drive motor 41 and the drive shaft 43, and the electric movement of the first sliding door 21 and the second sliding door 22 is stopped.
[0023]
According to the sliding door device 1 of this embodiment, since it is configured as described above, the sliding door device can be installed in a small installation space, and the first and second sliding doors are moved in synchronization. Easy to open and close the gate.
[0024]
In addition, since it can be automatically opened and closed by the drive motor, it can be opened and closed with a small force even when the sliding door is long.
[0025]
Furthermore, since it has a clutch mechanism that cuts off transmission of the driving force from the drive motor, it can be switched to manual opening / closing instead of automatic opening / closing in an emergency.
[0026]
In addition, the sliding door apparatus of this invention is not restrict | limited to the above-mentioned embodiment, It can change variously in the range which does not deviate from the meaning of this invention.
[0027]
For example, although an example in which a sprocket is used as a toothed rotating member and an endless chain is used as a rotational force transmitting member has been shown, an endless belt may be used instead of an endless chain using a pulley instead of a sprocket. A gear may be used instead of the sprocket. Furthermore, although the case where there were two sliding doors was described, three or more sliding doors may be provided.
[0028]

【The invention's effect】
The sliding door device of the present invention can easily open and close the sliding door without reducing the appearance, and can reduce the installation space of the sliding door device.
[0029]
Moreover, since the sliding door apparatus of this invention has an interlocking mechanism which moves a 1st sliding door and a 2nd sliding door interlockingly, it can open / close a sliding door rapidly.
[0030]
Furthermore, by providing a clutch mechanism that cuts off the driving force that drives the opening and closing of the sliding door, it is possible to switch from automatic opening and closing to manual opening and closing in the event of an emergency, which is excellent in safety.
