The gate 101 is vertically lowered, the cylinder portions 103c and 103c are fitted to the pivot shafts 103b and 103b, and both hinges 103 and 103 are set at the same time.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional configuration, since the gate 101 has a large weight of several tens of kilograms (for example, 50 kg or more), while the operator lifts the gate 101, the lower ends of the cylindrical portions 103c and 103c are connected to the pivot shafts 103b and 103b. It was extremely difficult for the worker to position the gate 101 above the upper end and concentrically face it, and to accurately vertically lower the gate 101, which was a tough task for the worker.

In view of the above points, the present invention has an object to provide an opening / closing support device for an opening / closing body such as a gate so that an operator can easily attach the opening / closing body such as a gate to a support such as a gate pillar. There is.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is provided with a pivot that is fixed to a side surface of a support body that is erected at a predetermined position at predetermined intervals in an upward and downward direction, and a pivot shaft that is protruded on each pivot. The doors and other opening and closing bodies are supported by a plurality of hinges that are fixed to the side edges of the doors and other opening and closing bodies at predetermined intervals in the vertical direction and have a tubular portion that is rotatably fitted to the pivot shafts. In the opening / closing support device for an opening / closing body such as a door that is openably / closably supported, in each of the above hinges, the height of the pivot of the upper hinge is lower than the height of the pivot of the lower hinge. It is characterized in that the cylindrical portions of each hinge are formed to have the same height.

[0007]

[Action]

 According to the above configuration, first, the opening / closing body is lifted, and the tubular portion below the opening / closing body is slightly fitted to the pivot shaft below the support body. Next, with the slightly fitted portion as a fulcrum, the opening / closing body is vertically raised so that the tubular portion above the opening / closing body is fitted to the pivot shaft above the support body, and the opening / closing body is raised. By vertically lowering, each hinge can be easily set.

Further, in the case of the present invention, since only the height of the pivots is changed and the heights of the respective cylinders are formed to be the same, the pivots having different heights are not exposed to the outside after being set. Not only does it worsen the appearance, but also the lower end of each tube is supported by each pivot, so when using the opening / closing body, an unreasonable load is not applied to the pivot or pivot of a specific hinge. The smooth opening / closing of the opening / closing body and safety can be ensured for a long period of time as in the conventional case.
