[Conventional technology]

As one type of hinge, a fixed body attached to the door side and a movable body attached to the door opening frame side are relatively bendable and extensible via a plurality of arms pivoted across the connecting ends of these bodies. A mounting board and an adjustment plate are interposed between a seat plate that is rotatably connected and fixed by coming into contact with the inner surface of the door opening frame, and a movable body that is stacked and fixed on the seat plate. There are things that have been done.

FIGS. 5 and 6 show typical examples of such hinges.

In FIGS. 5 and 6, a fixed body k attached to the inner surface of the door i and a movable body h attached to the inner surface of the mounting plate a of the door opening frame are two arms l extending over their connecting ends. , l' so that they can be relatively bent, extended, and rotated.

The base ends of the mounting board b and adjustment plate c combined with the movable body h are pivotally connected to each other via pins d, and the free ends thereof include
An adjusting screw e is provided which is screwed into the adjusting plate c and is rotatably held by the mounting board b to prevent it from coming off.

When the hinge illustrated in FIGS. 5 and 6 is attached across the door and the door opening frame, the process is as follows.

The fixed body k is embedded in the inner surface of the door i and fixed with screws.

The mounting board b and adjustment plate c are screwed to the inner surface of the mounting plate a.

Thereafter, the movable body h is placed over the adjustment plate c, and the screw g is screwed in from the movable body h side to the adjustment plate c, thereby fixing the movable body h to the mounting plate a.

In this installation mode, when screw g is loosened and adjusting screw e is turned, adjusting plate c is rotated with pin d as a fulcrum.
rotates in the direction of arrow ff' in FIG. 6, so the movable body h moves in the direction of arrow j-j' in the figure.

Thus, when the movable body h is adjusted to move in the above-mentioned j-j' direction, the amount that the door i covers the mounting plate a is adjusted.

After this adjustment, the screw g is tightened again.

Incidentally, a hinge having such technical content is disclosed in Japanese Utility Model Publication No. 7976/1983.

[The problem that the idea aims to solve]

In the case of the hinge described above, the mounting board b and the adjustment plate c
and are pivotally connected to each other via pin d.

In such a pivoting means, since it is necessary to rotate the mounting board b and the adjusting plate c relative to each other, it is necessary to provide a slight amount of slack in the pivoting portion.

However, like a hinge, each time it is opened or closed, the
In the case of a structure that is subject to vibration, in the long run, due to the lack of tightening force of the loosened portions, adjustment screws e and screws g become loosened, and the mounting position of door i relative to the door opening frame becomes misaligned.

In view of these technical problems, the present invention aims to provide a hinge that can prevent screws from loosening and ensure the accuracy of door installation over a long period of time.

[Means to solve the problem]

In order to achieve the intended purpose of this invention, a fixed body attached to the door side and a movable body attached to the door opening frame are connected via a plurality of arms pivoted across the connecting ends of these bodies. A mounting board is installed between a seat plate that is connected to the seat plate so as to be relatively bendable and rotatable, and that is fixed by coming into contact with the inner surface of the door opening frame, and a movable body that is stacked and fixed on the seat plate. In the hinge in which the adjustment plate is interposed, the adjustment plate is connected to one end of the mounting board, the mounting board and the adjustment plate are integrally formed, and the adjustment plate is located on the plate side of the mounting board. The mounting board is folded back and formed at the connecting portion between the mounting board and the adjustment plate, and has a spring property that resists the folding direction, and is integrated through the folded part. and an adjusting plate is interposed between the seat plate and the movable body, with the mounting board facing the seat plate and the adjusting plate facing the movable body, and the mounting board and the seat plate adjacent to each other are integrated. A first adjustment screw is formed or separately formed, and is screwed into the adjustment plate and is rotatably held by the installation board to prevent it from coming off, on the free end side of the mounting board and the adjustment plate. A second adjustment screw is provided on the folded side between the mounting board and the adjustment plate, and is screwed into the seat plate through the mounting board, and both adjustment screws are screwed into the seat plate. A third adjustment screw is provided between the screws, passing through the movable body side and screwed into the adjustment plate.

[Effect]

When the hinge according to the present invention is installed across the door and the door opening frame, the following will occur.

The fixing body is screwed to the inner surface of the door.

The seat plate is screwed to, for example, the inner surface of the mounting plate on the side of the door opening frame.

The mounting board and the adjustment plate are fixed onto the seat plate with the mounting board facing the seat plate and via adjustment screws extending between the mounting board and the seat plate.

The movable body is placed over the adjustment plate and fixed onto the adjustment plate via an adjustment screw extending between the movable body and the adjustment plate.

In the above, when the adjusting screw screwed into the free end side of the mounting board and adjusting plate is turned, the free end of the adjusting plate moves in the feeding direction of the adjusting screw ( Since the movable body supported by the adjustment plate also moves in the same direction, the amount that the door covers is adjusted.

Furthermore, in the above, when the adjustment screws that tighten the movable body and the adjustment plate together are removed, the mounting position of the movable body with respect to the adjustment plate (door opening frame) can be adjusted.

In the case of the hinge according to the present invention, the folded part formed at the connection part between the mounting board and the adjustment plate has a spring property that resists the folded direction, so there is no room for loosening here. Moreover, it absorbs and alleviates shock and vibration when opening and closing the door, and also functions as a spring back, making it difficult for screws to loosen.

As the adjustment plate 3 moves, the movable body 10
moves in the direction of the arrow Q or the direction of the arrow Q' in FIGS. 1 and 3, and the door 8 also moves in the same direction, so the amount of cover of the door 8 is adjusted.

In such a hinge configuration, since the folded portion 4 having spring properties applies elastic force in the direction of arrow P to the adjustment plate 3 using this as a fulcrum, the threaded portion 5a of the adjustment screw 5 and the adjustment plate The screw holes 3c of No. 3 become loose with each other, and no rattling occurs.

Therefore, the above-mentioned covering amount is always maintained properly, and the mounting position of the door 8 is unlikely to be misaligned.

[Effects of the invention] In the present invention, the mounting board and the adjustment plate, which are interposed between the seat plate and the movable body at a predetermined hinge, are integrally connected by a folded part that maintains spring properties. Since the plate is configured to be screwed to the seat plate and the movable body through each adjustment screw, by turning the predetermined adjustment screw,
The amount that the door covers the door opening frame can be adjusted.

Moreover, the above-mentioned folded portion having springiness in a predetermined direction not only has no room for loosening, but also
It also prevents the adjustment screw from loosening, so the door will not be installed in the wrong position over a long period of time.

Further, since the movable body, the mounting board, and the adjustment plate are separate bodies and are screwed together with adjustment screws, the adjustment function along the length direction of the movable body is not sacrificed.
