When assembling the frame-side hinge component and the door-side hinge component described above, with the door lifted upward, fit the shaft of the door-side hinge component above the insertion shaft of the frame-side hinge component. After aligning the joints, the door must be lowered and installed.
However, while the door is in the lifted state, for example, door-side hinge components are attached to the upper, lower, and center portions of the side surfaces of the door, and frame-side hinge components are attached to the upper, lower, and center portions of the inner surface of the frame. The work is not easy because it requires aligning the parts. When the door is heavy, it is not particularly easy for the worker to align the door with the door lifted, and there are also safety issues.

In order to solve the above-mentioned problems, the present invention has been made such that when assembling the door-side hinge components and the frame-side hinge components, the positions of the door-side hinge components and the frame-side hinge components are adjusted while the door is lifted. The present invention provides a frame-side hinge component or a door-side hinge component that includes a guide portion that allows easy alignment.

The hinge component according to the present invention comprises a frame-side hinge component attached to a frame and a door-side hinge component attached to a door to form a hinge that is attached to the frame so that the door can be opened and closed. A hinge component of either the frame side hinge component or the door side hinge component, which includes a guide portion for assembling the frame side hinge component and the door side hinge component ; The hinge component includes a lower shaft, an upper shaft that extends upward from the upper end surface of the lower shaft and has a smaller diameter than the lower shaft and is concentric with the lower shaft, and a lower shaft. It is fixed to the frame and has a plate surface extending from a portion of the outer peripheral surface of the side shaft portion extending along the central axis of the lower shaft portion in a direction along the central axis and in a direction orthogonal to the central axis. The door-side hinge component includes a tube portion with a lower end opening, and a portion extending along the central axis of the tube portion on the outer circumferential surface of the tube portion in a direction along the central axis and a fixing plate part having a plate surface extending in a direction perpendicular to the central axis and fixed to the door; It is made of a plate material that extends upward along the axis and has a plate surface facing the outer circumferential surface of the upper shaft part, or from a part of the outer circumferential surface of the pipe part of the door side hinge component. It is characterized by being constructed from a plate member provided so as to extend downward along the central axis.
Additionally, the guide section moves the door downward from a state in which the lower end opening of the tube of the door-side hinge component fixed to the door is positioned above the upper shaft of the frame-side hinge component fixed to the frame. When constructing a hinge by inserting the upper shaft part inside the pipe part and assembling the frame-side hinge component and the door-side hinge component, the lower end opening of the pipe part of the door-side hinge component It is characterized in that the pipe portion of the door side hinge component is guided downward after being positioned above the upper shaft portion of the frame side hinge component.
