Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a gate opening / closing device capable of electrically opening and closing a gate.

[Prior art]

The gate is formed by being horizontally rotatably supported by a hinge on a gate pillar or a gate wall, and the gate supported by the hinge is manually rotated. However, manually operating the gate is troublesome, and various attempts have been made to electrically open and close the gate. For example, by providing a motor and a drive shaft that is rotationally driven by the motor on a gate post or a gate wall, and mounting the gate by supporting the gate on this drive shaft
The gate can be rotationally driven according to the operation of the motor.

[Problems to be solved by the device]

However, when the gate is supported by the drive shaft that is rotated and driven by the motor in this way, the conventional structure in which the gate is horizontally hinged to the gate pillar or gate wall and the structure for supporting the gate are provided. However, there is a problem that the conventional gate cannot be used as it is and a large design change is required. Further, when the gate is thus supported by the drive mechanism portion such as the drive shaft, the weight of the gate acts on the drive mechanism portion, which causes a problem such as a failure or a shortened life. The present invention has been made in view of the above points, and it is possible to electrically open and close it by adding a simple modification to the hinge-supported gate, and there is a possibility that the failure or the life may be shortened. It is an object of the present invention to provide a gate opening / closing device that can be used without any use.

[Means for Solving the Problems]

The gate opening / closing device according to the present invention is a fixed side arm that pivotally supports a gate 2 on a gate support member 1 such as a gate pillar or a gate wall so as to be horizontally rotatable by a hinge 3 and fixes the hinge 3 to the gate support member 1. Four
And a pivot shaft 6 for rotatably connecting the fixed arm 4 and the pivot arm 5 to each other, and the pivot arm 6 fixed to the gate 2. The drive mechanism 7 is fixed to the outer surface of the member 1, the drive device 7 is arranged in the gate support member 1, and the transmission mechanism 8 for transmitting the drive of the drive device 7 to the rotation shaft 6 of the hinge 3 is provided at the opening of the side wall of the gate support member 1. The transmission mechanism 8 is connected to the lower end of the rotary shaft 6 which is inserted and led out from 12 and projects downward from the fixed arm 4 so that the rotary arm 5 rotates in conjunction with the rotary shaft 6. By adopting such a configuration, the above-described object of the present invention is achieved.

[Action]

According to the present invention, the drive of the drive device 7 arranged in the gate support member 1 is transmitted to the rotary shaft 6 of the hinge 3 by the transmission mechanism 8 to rotate the rotary shaft 6, and the rotary shaft 6 is rotated. The rotation side arm 5 can be rotated by the rotation of, and the gate 2 can be automatically rotated. Further, since the rotary shaft 6 of the hinge 3 is rotated by the drive device 7 to rotate the gate 2, the rotary shaft 6 of the hinge 3 and the rotary side arm 5 are used for automatically rotating the gate 2. It can also be used as a part of the device, reducing the number of members,
Further, since the driving device 7 is arranged in the gate support member 1, the appearance is improved without disturbing. Further, since the gate 2 is supported by the gate support member 1 by the hinge 3, the gravity of the gate 2 can be prevented from being directly applied to the drive device 7 in the gate support member 1.

【Example】

Hereinafter, the present invention will be described in detail with reference to embodiments. FIG. 1 shows an embodiment of the present invention. A gate 2 is pivotally supported horizontally by a hinge 3 on a gate support member 1 such as a gate pillar or a gate wall. Here, the hinge 3 is the gate support member 1
Fixed side arm 4 fixed to the gate 2 and rotation side arm 5 fixed to the gate 2.
And a rotating shaft 6 for rotatably connecting the fixed side arm 4 and the rotating side arm 5. A drive device 7 such as a motor and a sprocket 9 rotated by the drive device 7 are arranged in the gate support member 1, and the hinge 3 is also provided.
A sprocket 10 is fixed to the lower end of the rotary shaft 6. A drive string-like body 11 such as a chain, a belt or a wire rope is laid over both sprockets 9 and 10. Here, in this embodiment, the sprockets 9 and 10 and the drive string-like body 11 constitute the transmission mechanism 8. The drive string-like body 11 is led out from an opening 12 provided in a side wall of the gate support member 1. Regarding the connection relationship between the rotating side arm 5 and the rotating shaft 6, the rotating side arm 5 has the rotating shaft 6
It is connected to rotate in conjunction with. For example, the rotating shaft 6 and the rotating side arm 5 may be fixed to each other, or at least the upper part of the rotating shaft 6 may be formed into a square cross section, and the hole of the rotating side arm 5 may be formed into a square shape that fits exactly with this. Are fitted and connected. The rotating shaft 6 is rotatably passed through the fixed side arm 4. Then, the drive device 7 is driven to rotate the rotary shaft 6 of the hinge 3 via the transmission mechanism 8, and the rotary side arm 5 is rotated in conjunction with the rotary shaft 6, whereby the gate 2 To open and close. FIG. 3 shows another embodiment of the present invention. In this embodiment, the rotation of the drive unit 7 is changed by the gear mechanism 13 to the hinge 3
This gear mechanism is designed to be transmitted to the rotating shaft 6 of
13 is the transmission mechanism 8. By the way, the gate 2 is supported by a plurality of hinges 3 and 3'up and down with respect to the gate support member 1 as shown in FIG. 2, and the rotating shaft rotated by the drive device 6 as described above. One hinge 3 provided with 6 is enough, and another hinge 3 '
Should use normal hinges. In addition, in the embodiment shown in the accompanying drawings, the example of the single-open gate 2 is shown, but the double-open gate 2 may be used. In the case of the double-opened gate 2, only the one gate 2 can be automatically opened and closed by rotating the rotation shaft 6 of the hinge 3 of the one gate 2 by the drive device 7, and the other gate 2 May be manually opened or closed, or both of the gates 2 may be automatically opened and closed by rotating the rotary shafts 6 of the hinges 3 of the two gates 2 by the drive device 7, respectively. Is.

[Effect of device]

As described above, in the present invention, the fixed side arm that pivotally supports the gate on the gate support member such as the gate pillar or the gate wall so as to be horizontally rotatable by the hinge, and the hinge is fixed to the gate support member, and the gate. The fixed side arm is fixed to the outer surface of the gate support member, and the fixed side arm is fixed to the outer surface of the gate support member. A drive device is arranged inside, and a transmission mechanism for transmitting the drive of the drive device to the rotation axis of the hinge is inserted and led out from the opening of the side wall of the gate support member, and the rotation side arm rotates in conjunction with the rotation axis. Since the transmission mechanism is connected to the lower end of the rotating shaft that protrudes downward from the fixed side arm so as to move,
The drive of the drive device is transmitted to the rotary shaft of the hinge via the transmission mechanism so that the gate can be opened and closed, and the gate that is supported horizontally by the hinge can be electrically opened and closed as it is. Further, since the gate is supported by the gate support member by the hinge, there is no fear that the gravity of the gate will be applied to the drive mechanism portion, and it is possible to prevent the drive mechanism portion from breaking down or shortening its life. It is a thing. Further, since the pivot shaft of the hinge is pivoted by the drive device to pivot the gate, the pivot shaft of the hinge and the pivoting side arm are part of the device for automatically pivoting the gate. Since it can be used in common, the number of members can be reduced, and since the driving device is arranged in the gate support member, it does not get in the way and has a good appearance.
