Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate that automatically opens and closes.

[0002]

2. Description of the Related Art Conventionally, when the gate is open, the gates are stacked on top of each other, and when the gate is closed, those doors move between gate posts to open and close. It has been known. In this gate, casters are attached to the lower surface of each door, and one of those doors is fixed to one gate post.

When the gate is closed, the front door is moved to the other gate post side, and the other doors are moved in tandem with this to close the gate, and when the gate is opened, the front door is opposite to this. When one is moved to the side of the gate, the other doors are moved to the original position in line with this and are stored in a state where they overlap each other.

[0004]

However, since the gate as described above is manually opened and closed, the opening and closing work is troublesome, and it has been necessary to carry out the operation with an umbrella, especially when it is raining or the like. . Furthermore, since this gate is moved by the casters on the lower surface of the door, there is a problem that the moving direction is not fixed and opening and closing is difficult. The present invention has been made in view of the above problems, and an object thereof is to provide a gate that can be automatically opened and closed and that has a stable moving direction.

[0005]

A gate of the present invention for achieving the above object comprises a fixed door fixed to a drive unit located on one gate pole side and a plurality of movable doors. Multiple movable doors move between gate posts to open and close the gate, and when the gate is closed, the movable doors move to the other gate post side and the end of each door overlaps the end of the adjacent door. In addition, when the gate is opened, the movable door is stored in a state where the movable door and the fixed door substantially overlap each other.In the gate, a fixed door and a plurality of movable doors are mounted on a rail laid between the gate posts. The drive section is provided with a drive side sprocket and a driven side sprocket at a predetermined interval, and a driven side sprocket is provided at both ends of the lower surface of the movable door excluding the movable door at the tip and the lower surface tip of the fixed door. , The drive side sprouting in the drive section And Tsu door and the driven sprocket,
A chain is stretched around the fixed door and the driven side sprocket of the movable door, one end of the chain is fixed to the movable door at the tip via the driving side sprocket in the drive section, and the other end of the chain is driven in the drive section. The configuration is characterized in that it is fixed to the movable door at the tip through the side sprocket and the driven side sprocket of the fixed door and the movable door.

[0006]

[Function] When the gate is open, the movable door is stored with the fixed door overlapping the fixed door, and when closing the gate from this state, the chain can be rotated by the clockwise rotation of the drive side sprocket that can be placed in the drive unit. From the front door of each movable door, move on the rail to the side opposite to the fixed door and close the gate. Then, in order to open the door from this state, when the drive side sprocket is rotated counterclockwise, the chain rotates and the chain moves sequentially from the movable door at the tip to the fixed door side and sequentially overlaps with the fixed door. Is opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the gate of the present invention will be described in detail below with reference to the drawings. 1 is a front view of the gate, FIG. 2 is a plan view thereof, and FIG. 3 is a sectional view thereof.

The gate 1 of the present invention is formed by mounting a fixed door 4 and a movable door 5 on a rail 3 laid inside the gate pillars 2a and 2b, and the fixed door 4 has a rear end of a door panel 6 as a gate pillar. The door panel 6 is fixed to the drive unit 7 mounted on the rail 2a, and the front end of the door panel 6 is mounted on a dolly 9 provided with a door roller 8 rolling on the rail 3 via a support 9a. Door panel 6
A guide rail 11 on which the guide roller 10 of the movable door 5 rolls is provided on the lower surface of the.

Similar to the fixed door 4, the movable door 5 is provided with a carriage 9 provided with a door roller 8 rolling on the rail 3 at the tip of a door panel 6 via a support body 9a, and a rear end side surface thereof. A guide roller 10 is provided, and the guide roller 10 is placed on a guide rail 11 on a door panel 6 of the fixed door 4 and the movable door 5 which are adjacent to each other.

Therefore, when the gate 1 is open, as shown in FIG. 7, the movable door 5 and the fixed door 4 are housed in a state where they overlap each other, and when the gate is closed. As shown in FIG. 2, the movable door 5 extends in a state where the ends of the fixed door 4 and the movable door 5 overlap each other.

Further, driven side sprockets 12 are provided at both ends of the lower surface of the door panel 6 of the movable door 5 excluding the movable door 5a at the tip and at the tip of the lower surface of the door panel 6 of the fixed door 4. A chain 14 is stretched over the driven side sprocket 12, the driving side sprocket 13 and the driven side sprocket 12 provided in the drive unit 7, and one end of the chain 14 is attached to the movable door 5a at the tip via the driving side sprocket 13. While being fixed, the other end from the driven side sprocket 12 of the drive unit 7 to the driven side sprocket 12 of the fixed door 4, and the driven door sprocket 12 from the driven side sprocket 12 through the driven side sprockets 12 of the movable door 5 has a tip end movable door It is fixed to 5a.

Further, the drive motor 15 in the drive unit 7 for driving the drive side sprocket 13 is operated by a distance operation or by a drive switch (not shown) in the drive unit. Of course, these should be used together. You can also

Next, the operation of the gate will be described with reference to FIGS. 7 and 8. First, when closing the gate from the state where the gate is open in FIG. 2, when the "close" button of the drive switch which is placed on the remote control or the drive section is turned on, the drive motor 15 is driven and the drive side sprocket 13 is moved. Rotate clockwise to rotate the chain 14. By this rotation, the carriage 9 of the movable door 5 at the tip travels on the rail 3, and the guide roller 10 travels on the guide rails 11 of the fixed door 4 and the movable door 5 and moves to the other gate post 2b side. The other movable doors 5 also move in conjunction with this to close the gate.

Next, in order to open the gate from the closed state, when the "open" button of the drive switch is pressed, the drive motor 15 rotates counterclockwise in the opposite manner to the above, and the chain 14 is rotated. To rotate. With this rotation, the carriage 9 of the movable door 5a at the tip travels on the rail 3, and the guide roller 10 travels on the guide rail 11 of the movable door 5 and the fixed door 4 adjacent to each other and moves to the fixed door 4 side. at the same time,
The other movable doors 5 also move in conjunction with this to open the gate. In addition, the ON-O of this drive switch
The FF can be operated by remote operation or manual operation.

[0015]

A fixed door and a plurality of movable doors are placed on a rail laid between the gate poles, a drive side sprocket and a driven side sprocket are provided at a predetermined interval, and a tip is provided. The driven side sprockets are provided at both ends of the lower surface of the movable door excluding the movable door and at the front end of the lower surface of the fixed door.The driven side sprockets of the drive section and the driven side sprockets of the fixed door and the movable door are chained. And one end of the chain is fixed to the movable door at the tip through the driven side sprocket in the drive section, and the other end of the chain is connected to the drive side sprocket in the drive section and the driven side in the fixed door and the movable door. Since it is fixed to the movable door at the tip via the sprocket, the movable door is rotated by the rotation of the drive side sprocket. It can automatically open and close the gates moving on Le.
