し、フロアの外観等を悪化させる問題があった。In a door hinge device of this type, a door closer is generally provided in a floor hinge for automatically closing an opened door, but the door is opened in both directions. For a double door,
There is a problem that the structure of the door closer becomes large and the manufacturing cost of the device becomes high. This also increases the size of the floor hinge as a whole, and when the floor hinge is actually buried in the floor, the cover panel of the floor hinge increases the area where tiles and other flooring materials cannot be attached, increasing the floor area. There is a problem that the appearance and the like are deteriorated.

ドアクローザが突出し、外観を悪くする問題があった。[0004] Conventionally, as a door hinge device for a double door or the like, a spring-type door closer has been used. However, this type of conventional door closer has two coils because the door is incorrect on both sides. Because the springs are arranged side by side, the shape becomes large, and when it is attached to the edge of the door,
There was a problem that the door closer protruded and the appearance was deteriorated.

す方向、つまり平面視で時計方向に回動力が生じる。When the door is opened, for example, in a counterclockwise direction in a plan view, the main body case is rotated in the same direction together with the door because the rotating shaft is fixed to the receiving bracket. Pivoted in the direction. Therefore, the locking pin pushes the locking portion to rotate the lower locking member counterclockwise, whereby the coil spring in the main body case is rotated in the same direction. At this time, since the upper locking member on which the upper end of the coil spring is locked cannot abut on the locking pin of the rotating shaft and cannot be rotated, the coil spring is twisted, and there is a direction of returning the twist, that is, a plan view. Produces a clockwise turning force.

生じる。When the gate door 20 is opened, for example, in a counterclockwise direction in a plan view, since the rotating shaft 4 is fixed, the body case 2 is rotated in the same direction together with the gate door 20, whereby the engagement on the bottom plate 5 is established. The stop pin 5b is rotated in the same direction. Therefore, the locking pin 5b pushes the locking portion 7b to rotate the locking member 7 in the counterclockwise direction, whereby the coil spring 8 in the main body case 2 is rotated in the same direction. At this time, since the locking member 6 to which the upper end of the coil spring 8 is locked cannot abut on the locking pin 4c and cannot be rotated, the coil spring 8 is twisted, and the torsion is returned there, that is, in plan view. Clockwise rotation is generated.

The stop pin 3b is rotated in the same direction. For this reason,
The locking pin 3b pushes the locking portion 6b to rotate the locking member 6 clockwise, whereby the coil spring 8 in the main body case 2 is rotated in the same direction.
