In this one, a base end of a shaft support plate extending in a horizontal direction whose tip is orthogonal to the mounting substrate is screwed to the inner surface of the mounting substrate of a vertical plate and a horizontal plate and having an L-shaped side view, It has a structure in which a vertical door support shaft is attached to the tip of the shaft support plate. In this shaft seat, the shaft support plate and the mounting board are separately configured so that they can be shared by left and right hands, and the mounting direction of the shaft support plate with respect to the mounting board can be selected to the left or right depending on the form of use. It is like this. And the shaft support plate is
It is fixed to the mounting substrate with a single screw in the center, and is also prevented from rotating by fitting a notch formed on the back surface of the shaft supporting plate into the horizontal plate of the mounting substrate.

[0003]

By the way, in the above-mentioned conventional device, the mounting substrate and the shaft supporting plate, which are separately configured, are turned in accordance with the usage pattern, and the notch is fitted to the horizontal plate while screwing. Since they are connected, the mounting substrate and the shaft support plate must be stored separately, and the assembly work on site is troublesome, and there is a problem that the handling is not convenient. Furthermore, once assembled, the shaft support plate is prevented from rotating by fitting the notch and the horizontal plate, so there is no adjustment allowance in the direction of rotation around the screw of the shaft support plate, and therefore the joint adjustment of the door ( Adjustment in the width direction along the surface of the door) was difficult.

Therefore, the present invention is excellent in convenience of handling,
Also, it is an object of the present invention to provide a pivot hinge shaft seat capable of easily adjusting a joint of a door.

In order to achieve the above object, the present invention has a side view shape of a vertical plate and a horizontal plate which is L.
It is composed of a V-shaped mounting board and a shaft support plate whose base end is fixed to the inner surface of the horizontal plate of this mounting board and whose tip extends in the horizontal direction orthogonal to the mounting board. In a shaft seat of a pivot hinge to which a shaft is attached, a base end of the shaft support plate is rotatably coupled to an inner surface of a horizontal plate of the mounting substrate by a pin, and the shaft support plate is provided around the pin with respect to the horizontal plate. It is characterized in that a screw for fixing is provided and a through hole for this screw is formed as an elongated hole that allows the rotation.

[0006]

When the door is supported by using the pivot hinge seat having the above construction, first the horizontal plate of the mounting board is aligned with the horizontal frame of the opening for mounting the door, and the vertical plate of the mounting board is set to the vertical frame of the opening. Fixed to. Then, depending on whether it is left-handed or right-handed, align the direction of the shaft support plate and lightly screw the shaft support plate to the mounting board. At that time, the lower side has the door support shaft directly attached to the tip of the shaft support plate in advance. Further, the upper side is left with a hole without attaching the shaft supporting shaft. Next, the door fittings attached to the upper and lower ends of the door are aligned with the upper and lower shaft support plates, respectively, and the lower holes of the fittings on the door side are dropped into the shaft support shaft. Regarding the upper side, the door support shaft is inserted from the door side (lower side) and the tip of the support shaft is inserted into the hole on the shaft support plate side.
In that state, fix the door support shaft to the door side with a set screw.

Next, in order to adjust the joint of the door, the position of the shaft support plate is adjusted with respect to the mounting substrate. In this case, the shaft support plate is rotatable because the screw through hole is a long hole. Therefore, by rotating the shaft support plate, the distance between the door support shaft and the vertical plate, that is, the support shaft and the vertical plate can be changed. The distance to the frame can be adjusted. Therefore, by adjusting this distance, the door can be finely moved in the width direction along the surface thereof, and the joint of the door can be adjusted.
