May be provided directly on the movable wing (4), but the one shown is provided on the wing-side fixed body (7c) which is a component of the hinge (7).

Next, the hinge (7) is a door side fixed body (7a),
The arm (7b) and, as described above, the wing side fixed body (7c) are provided. The door side fixed body (7a) of the hinge (7) is fixed to the back surface near the free end of the hinged door (3) with screws or the like.

The door side fixed body (7a) rotatably supports the lower end of the arm (7b) on the shaft (8). Arm (7
b) is an acute angle E (smaller than 90 °) in the direction of the free end where the angle with the back surface of the hinged door (3) in the door-side fixed body (7a) is constant.
Will be stopped at.

The lower end of the arm (7b) shown in the drawing abuts against the inner wall of the door-side fixed body (7a) so that a constant acute angle E is obtained.
It is configured to stop at. Next, the wing-side fixed body (7c) is rotatably attached to the upper end of the arm (7b) at the shaft (10).

As described above, the shaft (10) of the blade-side fixed body (7c) is positioned substantially at the boundary line between the blade main portion (4a) and the extending portion (4b) of the movable blade (4). is there. Axis (1
In order to make the position of (0) such as that, in the illustrated embodiment, the movable blade (4) is provided with a notch from the trailing edge so that the blade fixed body (7).
c) is installed. Next, the wing-side fixed body (7c) always receives the rotational force inclined toward the free end of the hinged door (3) with respect to the arm (7b) by an elastic means such as a spring.

That is, in the illustrated embodiment, a spring (9) is mounted on the outer periphery of the shaft (10) to apply a rotational force to the blade-side fixed body (7c). As is clear from the above description, the movable wing (4) is naturally in the rear surface of the hinged door (3) due to both the rotational force on one shaft (10) and the stopping function on the other shaft (8) at a constant acute angle E. It will be tilted toward the free end and will be stationary.

That is, the angle between the arm (7b) and the movable wing (4) always tries to be closed by an elastic means such as a spring (9), while the arm (7b) is relative to the door side fixed body (7a). In the natural state, the front end of the movable wing (4) is in contact with the back surface of the hinged door (3) and the rear end is up to the position where the arm (7b) is stopped at the constant acute angle E because it does not open from the constant acute angle E. (The state of FIGS. 1 and 2).

The operation of the hinged door device shown in the above embodiment is as follows. That is, when the hinged door (3) is closed from the state shown in FIGS. 1 and 2, the front surface of the magnet catch provided on one or both of the top plate and the floor plate of the main body of furniture or the like is applied to it. ) Movable wings (4)

When the rear end of the extending portion (4b) of the movable blade (4) contacts the movable blade guide (6) and further closes the hinged door (3), the extending portion (4b) is extended as shown in FIG. Is pushed, the movable blade (4) rotates about the shaft (10) against the rotational force of the elastic means such as the spring (9) and is pressed along the movable blade guide (6).

When the hinged door (3) is further closed, the arm (7b) inclines about the shaft (8) and the movable blade (4) is guided by the movable blade guide (6) as shown in FIG. While invading the back of the other hinged door (2).

When the hinged door (3) is finally closed, FIG.
The movable wing (4) will close the gap between the free ends of both hinged doors (2) and (3) as shown in FIG. Next, when the hinged door (3) is opened from the state shown in FIG.
1 to the state of FIG. 1 in the reverse order of the above.

During this opening process, the rotating force of the elastic means such as the spring (9) centering on the shaft (10) serves as the driving force to restore the movable blade (4) to the natural state.
On the other hand, the other hinged doors (2) can be freely opened and closed regardless of the movable wings (4).

FIG. 6 shows another hinged door device, which has the following features in comparison with the one shown in FIG. That is, the shape of the wing-side fixed body (7c) of the hinge (7) is different.

FIG. 7 shows another hinged door device, which has the following features as compared with the one shown in FIG.

That is, the blade main portion (4a) of the movable blade (4) is made of a plate material, while the extending portion (4b) is attached to one or both of the upper end and the lower end of the movable blade (4). 11)
Corresponds to this. The extending portion (4b) of the movable wing (4) has an original purpose of rotating the movable wing (4), and thus may be provided only in a necessary portion as shown in FIG.

In the embodiment shown in FIG. 7, an L-shaped plate made of, for example, a synthetic resin material is used as the wing tip material (11).

FIG. 8 shows another hinged door device, in which a stepped portion (16) is provided on the rear surface of the hinged door (2). The step portion (16) improves the sealing property by pressing the elastic body (12) provided at the tip of the movable blade (4).

FIG. 9 shows another hinged door device, and the hinged door device extends to only one of the upper end and the lower end (the upper end in the figure) of the movable blade (4) (hence the movable blade guide (6)).
Also). In this case, since the movable blade (4) receives a biased force from the upper end, the width L of the upper hinge (7) is widened and consideration is given so that the force is transmitted to the entire movable blade (4). Be done. Further, it is desirable that the hinge (7) (particularly the arm (7b)) is made of a material such as a metal which is strong against twisting. When the length of the movable blade (4) is long, a method for providing the movable blade guides (6) at both the upper end and the lower end, or FIG.
It is desirable to apply the aforementioned method of.

FIG. 10 shows another hinged door device. In the hinged door device, rubber, foam, synthetic resin material, cork, non-woven fabric or the like is attached to the back surface of the hinged door (3) with which the tip of the movable wing (4) abuts. A padding (15) made of cushioning material is provided. The padding material (15) may be one that extends in the vertical direction of the hinged door (3) or one that is only the upper and lower ends.

The backing material (15) is provided in consideration of the danger that the movable wing (4) may hit the rear surface of the hinged door (3) to make a sound and the danger that the rear surface of the hinged door (3) may be damaged by long-term use. .

In FIG. 11, the rear end of the extending portion (4b) of the movable blade (4) has three positions, namely, a position A rearward from the normal line from the shaft (8), a position B substantially on the normal line and a front position C. To explain. That is, the rearward position A is most advantageous in that the force from the movable blade guide (6) is transmitted to the rotation about the axis (10) which is the first movement of the movable blade (4). However, the position B may be on the substantially normal line, and the rear position C may be used.
However, the operation is possible when the hinged door (3) is closed with inertia.

12 and 13 show a hinge of a hinged door device according to the present invention. The hinged door device has a leaf spring or a wire spring (coiled on the back surface of the hinged door (3) with which the tip of the movable wing (4) abuts. (Including those) or plate-like or linear spring means (5)
Is fixed to the hinged door (3). The plate-like or linear spring means (5) is a concept including both a plate-like or linear spring itself and a plate material or a wire material subjected to a force by the elastic means. The plate-shaped or linear spring means (5) shown is interposed between the door-side fixed body (7a) of the hinge (7) and the rear surface of the hinged door (3) and the hinged door (3) is fixed at the same time. Considered to be fixed to the back of the. It should be noted that the door-side fixed body (7a) of the hinge (7) is provided with a screw hole at least on the free end side of the hinged door (3). Here, at least the meaning means that screw holes may be provided not only on the free end side of the hinged door (3) but also on both sides of the door side fixed body (7a), behind or both. Next, the plate-like or linear spring means (5) is shown as being cantilevered and projected from the door-side fixed body (7a) in a free state. Therefore, the tip of the movable blade (4) elastically contacts the plate-shaped or linear spring means (5) shown in the figure. Therefore, when the movable wing (4) returns, the plate-shaped or linear spring means (5) decelerates the movable wing (4) and the movable wing (4) collides with the back surface of the hinged door (3). Is prevented by.

The plate-like or linear spring means (5) is usually provided for each hinge (7), but when three or more hinges (7) are used, there may be no hinge (7). . Although the plate-shaped or linear spring means (5) is fixed together with the hinge (7), only the plate-shaped or linear spring means (5) may be separately fixed by screws or the like. Since the plate-shaped or linear spring means (5) can be thin, thin or small in volume, it is possible to prevent the movable blade (4) from being lifted up from the rear surface when the hinged door (3) is closed. To When a leaf spring (one or more, one using a perforated plate for adjusting the force, etc.) is used as the plate-like or linear spring means (5), the tip of the leaf spring is fixed to the movable blade (4). You may fold it slightly downward or fold it in the opposite direction so that it will not get caught. The reason why the door-side fixed body (7a) of the hinge (7) is provided with a screw hole at least on the free end side of the hinged door (3) is only for fixing the plate-shaped or linear spring means (5). is not. The screw hole on the free end side is also set at that position because the force is applied by pulling from the direction of the force applied to the door-side fixed body (7a) of the hinge (7).
