A large door with an opening that can slide laterally, a small door that is attached to the front end of the large door in a sliding door type or a sliding door, and is narrower than the large door, and the large door is fully closed In this case, a fully closed detection means for detecting this and a fully open detection means for detecting the fully open state of the small door are provided, and further, the fully closed detection means detects the fully closed state of the large door. It is characterized by comprising control means for enabling the opening and closing operation of the small door only when the small door is opened, and for sliding the large door only when the full opening detecting means detects the full opening of the small door. is there.

[Embodiment] The present invention will be specifically described below based on the illustrated embodiment.

FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a plan view thereof, in which reference numeral 1 is a sliding door type gate.

The sliding door type gate 1 mainly includes a large door 2, a small door 3 and an opening / closing mechanism 4 (see FIG. 5) for opening and closing the doors.

The large door 2 connects the horizontal rails 5 and 6 arranged above and below with a large number of vertical rails 7, and at the rear side of the horizontal rails 5 and 6, reinforcing rails 8 and 9 are arranged in parallel with them to extend in the width direction. Multiple reinforcing ribs
10 and each of the crosspieces are connected. As shown in FIG. 2, the width W of the large door 2 is a width obtained by subtracting the width that allows one person to pass from the opening width P of the gate columns G1 and G2, more specifically, about 90 cm shorter than the opening width P. Width. The large door 2 is a gatepost G
A guide roller 12 pivotally supported on the lower surface of the reinforcing rib 10 is placed on two rails 11 laid between 1 and G2, and is moved along the rails 11 by an opening / closing mechanism 4 described later.

A small door 3 is hinged at the front end of the large door 2 in the moving direction.
It is attached so that it can be opened and closed via 13 (see FIG. 5).
This door 3 has a plurality of vertical bars 15 fixed to a metal frame body 14. When the large door 2 is closed at the same height as the large door 2, a space generated between the large door 2 and the gate post G1. Is the same width as. The small door 3 is folded inward from the hinge portion 13 when the large door 2 is opened (see FIG. 3). A small door opening / closing mechanism 16 (see FIG. 6) described later is attached to the small door 3.

Next, the opening / closing mechanisms 4 and 16 for the large door 2 and the small door 3 will be described.

First, the opening / closing mechanism 4 of the large door 2 will be described. As shown in FIG. 4, the large door 2 is opened, and the drive sprocket 19 and the driven sprocket 20 are inserted into the groove 18 provided in the ground of the storage 17 for storing the large door 2. A drive chain 21 is endlessly hung between these sprockets, and the drive sprocket 19 is connected to a drive motor 22 that rotates forward and backward by a control device by a chain 23. Also, the drive chain 21
Has a large door 2 attached to it. The mounting position is large door 2
Below the reinforcing rib 10 on the rear end side, as the drive chain 21 travels, the attachment part moves to the drive sprocket 19 side when the large door 2 is in the stored state, and to the driven sprocket 20 side when the large door 2 is in the closed state.

Next, the drive mechanism 16 for the small door 3 will be described. That is, as shown in FIGS. 5 and 6, the brackets 24 are attached to the upper and lower frame portions 14a and 14b of the frame body 14 of the small door 3 to attach these brackets.
A piston rod 26 of an electric power cylinder 25 whose end is attached to the bracket 2a on the side of the large door 2 is attached to 24, and the small door 3 is opened and closed by moving the piston rod 26 forward and backward. Each of the electric power cylinders 25 is connected to the control device 27 so as to operate only when the small door 3 is opened and closed after the large door 2 is completely closed (when the large door is closed).

The opening / closing mechanisms 4 and 16 for the respective doors are connected to a control device 27 arranged on the side of the storage 17 of the large door 2 and operated by a signal from this control device.

Further, lock devices 28 and 29 for locking each door are attached to both the large door 2 and the small door 3.

The lock device 28 on the side of the large door 2 locks the guide roller 12 when the large door 2 reaches the completely closed position.
When the dog 30 mounted on the lower surface of the rear end side comes into contact with the detection portion 31 arranged on the front end side of the groove 18, the lock device 28 moves the roller.
When 12 is locked and the closed small door 3 is completely opened, the inside of the free end of the small door 3 is a reinforcing rib at the tip of the large door 2.
It is configured to unlock when it comes into contact with the detection unit 33 (see FIG. 3) attached to the unit 10.

On the other hand, the lock device 29 on the small door 3 side is composed of an engagement hole 34 provided on the free end side of the small door 3 and an electric lock 35 provided on the gate post G1 side, and is connected to the control device 27.

As shown in FIGS. 5 and 6, the electric lock 35 has the latch 35a of the electric lock 35 fitted into the engagement hole 34 and engaged when the small door 3 is completely closed, so that the opening is opened. Closed with large door 2. Further, when there is a visitor during closing, the small door 3 is unlocked, for example, by an operation from a guard station, and then the opening / closing mechanism 16 for the small door 3 is operated so that a person can enter. It can be opened and closed again.

[Operation] Next, the operation of the sliding door type gate having the above configuration will be described.

First, the case of closing the gate in the open state will be described. When the motor 22 of the opening / closing mechanism 4 is driven by an appropriate switching operation, this rotation is transmitted to the drive sprocket 19 by the chain 23 and at the same time, the drive sprocket.
Drive chain 21 hung between 19 and driven sprocket 20
To rotate. Since the large door 2 is attached to the drive chain 21, the large door 2 moves in the closing direction along the rail 11 as the chain 21 travels. When the large door 2 reaches the stop position, the dog 30 attached to the end of the door 2 abuts on the detection portion 31 arranged at the tip of the groove 18, and the locking device 28 of the large door 2 operates to guide the guide roller 12 The motor 22 senses that the dog 30 has come into contact with the detection unit 31, and stops the rotation.

When the large door 2 stops at the closed position, a signal from the control device 27 causes the cylinder 25 to operate and the piston rod 26
Is extended. Since a small door 3 connected to a large door 2 by a hinge 13 is attached to the tip of the rod,
The extension of 26 causes the small door 3 to rotate in the closing direction with the hinge 13 as the center of rotation. Then, when the latch 35a of the electric lock 35 arranged on the gate G1 is engaged with the engagement hole 34 provided at the tip of the door 3,
The closing is completed and the operation of the cylinder 25 is stopped at the same time, so that the opening formed by the gate columns G1 and G2 is completely closed.

If there is a visitor at the time of complete closing, the small door 3 is unlocked by an appropriate switching operation, and the opening / closing mechanism 16 of the small door 3 is operated to open the small door to the extent that one person can pass, After passing the visitor, the opening / closing mechanism 16 is operated again to close the small door 3.

Next, the case of opening the gate 1 which is completely closed will be described. First, the small door 3 is unlocked and the opening / closing mechanism 16 is operated to rotate the small door 3 to the completely open position (storage position). When the small door reaches the completely open position, the inside of the door 3 comes into contact with the detection portion 33 attached to the large door 2 and the locking device 28 of the large door 3
Is released and the guide roller 12 is unlocked. Next, when the drive motor 22 is driven to drive the drive chain 21 in the opening direction, the large door 2 moves in the opening direction along the rail 11 and abuts against the stopper S provided at the end of the groove 18 to stop and open. The part is opened.

In the above embodiment, the small door 3 is hinged to the large door 2.
Although it is rotatably connected via 13, the rail 41 is attached to the upper and lower frames 40a and 40b of the large door 40 as shown in FIG. 7, and the small door 42 is slidably housed along the rail 41. You may do it. Further, although the drive chain is used as the opening / closing mechanism of the large door in the above embodiment, the present invention is not limited to this, and a rack, a combination of pinions or a wire instead of the chain may be used.
Further, the large door may be manually pressed to open and close without using the driving mechanisms. On the other hand, the opening / closing mechanism of the small door is not limited to the power cylinder in the above-mentioned embodiment, but a door check or the like may be used.

Alternatively, a generator such as a voice or a buzzer may be incorporated in the control device, and these may be activated when the gate is closed to call attention.

Furthermore, the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the spirit of the invention.
It goes without saying that the design can be changed.

[Effects of the Invention] Since the present invention has the above-mentioned configuration, it is safe because a person is not caught between the gate and the pillar when the gate is closed.

Further, the gate of the present invention can be used as a small gate part as a general gate, and it is not necessary to separately install a general gate beside the gate pillar.
