Abstract

PURPOSE:To improve the appearance on opening a hinged door, by providing a movable blade along the inside of the rear free end of one side hinged door and holding it so as to be freely rotatable through an arm and projecting the movable blade toward the other side hinged door when closing the door. CONSTITUTION:A hinged door 3 is closed, the rear end of extended part 4b of a movable blade 4 abuts on the movable blade guide 6 attached to the upper and lower part of a box body. Then the extended part 4b is pushed and the blade 4 rotates around the shaft 10, resisting against the torque of elastic means of a spring 9 or the like and it is pressed along the guide 6. Next, the arm 7b slants around the axis 8 and the blade 4 projects to the rear face of the other side hinged door 2 while being led by the guide 6. When the hinged door 3 is completely closed, the blade 4 closes the clearance between the free ends of the hinged doors 2, 3. Further at this time, the extended part 4b is formed by a blade end material 11. The thickness thereof is made about one third of the chief part of blade. In this way, the movable blade is prevented from extending in the free condition and the appearance can be improved. Further, it can be used for making an enclosed space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hinged door device of the present invention will be described below with reference to an embodiment shown in the drawings. 1 and 2 show a hinged door device according to the invention, which has hinged doors (2) (3) with their free ends abutted.

A movable wing (4) is attached to the back surface of the hinged door (3) near the free end along the free end.
The movable wing (4) includes a wing main part (4a) and the wing main part (4a).
Has an extending portion (4b) continuously extending rearward from.

The blade main portion (4a) and the extending portion (4b) are conceptual parts corresponding to the front portion and the rear portion of the movable blade (4), respectively. The extending portion (4b) shown in the figure is formed of a tip material (11) such as a metal or a plastic material. The movable blade (4) is provided on the boundary line between the blade main portion (4a) and the extending portion (4b).
Axis (10) of which is positioned. The shaft (10) of the movable blade (4) may be provided directly on the movable blade (4), but the one shown is provided on the blade-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.
It is stopped at (preferably 60 ° to 70 °).

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. 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) abuts against the back surface of the hinged door (3) because the arm (7b) stands up to a 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). Here, in order to assist the rising of the arm (7b), elastic means other than the elastic means such as the spring (9) may be provided on the shaft (8), for example.

The operation of the hinged door device of the present invention shown in the above embodiment is as follows. That is, when the hinged door (3) is closed from the state of FIG. 1 and FIG. 2, the movable wing guide in which the front surfaces of the magnet catches (5) provided on both the top and bottom of the box body and the like are applied thereto The rear end of the movable wing (4) approaches (6).

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 pushed to move the movable blade (4b). 4) is a spring (9)
It is rotated around the shaft (10) against the rotational force of the elastic means such as and is pressed against the movable blade guide (6).

When the hinged door (3) is further closed, the arm (7b) inclines about the shaft (8) and the movable wing (4).
While being guided by the movable wing guide (6), it invades the back surface 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.
From the state of, the procedure proceeds in the reverse order.

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).

The wing tip material (11) of the hinged door device as described above has a thickness (for example, 0 mm) or less (for example, 0 mm or less) about 1/3 of the thickness (for example, 6 mm) of the wing main portion (4a) of the movable blade (4). 0.5 mm)
To be By making the blade tip material (11) thin in this way, the gap between the hinged doors (2) (3) and the movable blade guide (6) becomes thin, and the tightness of the upper and lower ends of the movable blade (4) is improved.

The back of the hinged doors (2) and (3) and the movable wings (4)
There is also a method of using a warped movable blade (4) as shown in FIG. When the upper and lower ends of the movable wing guide (6) are pressed by the warpage, the movable wing (4) is brought into close contact with the rear surfaces of the hinged doors (2) and (3) over the entire surface.

When the airtightness is required, an elastic material (12) is provided around the rear edges of the hinged doors (2) and (3) as shown in FIGS. 5 and 6. The elastic material (12)
For example, rubber having a substantially V-shaped cross section as illustrated may be used.

The elastic member (12) shown is a hinged door (2).
It is illustrated that not only the seal between (3) and the movable wing (4) but also the seal between the hinged doors (2) and (3) and the box body is continuously performed. If magnetism is added to the elastic material (12) and the movable blade (4) is made of a magnetic material so that both can be adsorbed, it is suitable for a more required application of hermeticity.

[0023]

The embodiments of the hinged door device of the present invention are as described above, and the effects are listed below. (1) In the hinged door device of the present invention, in particular, in the natural state, the movable wing is inclined toward the free end direction on the back surface of one of the hinged doors by the action of the hinge or the like, so that the movable wing does not project and the appearance is clean. (2) The hinged door device of the present invention can be used in applications where it is necessary to hermetically seal, since the movable blades linearly invade the rear surface of another hinged door, so that the gap between the movable blades and the rear surface of the hinged door can be almost eliminated. To be
