Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hidden hinge of a four-axis type in which a door is arranged inside an opening of a fixed frame body when the door is closed.

[Prior art]

A four-axis type hidden hinge in which each component such as a fixed blade and a rotating blade is hidden in the opening of the fixed frame and the back side of the door when the door is closed is already known. Since the relative positions of the four axes are designed and changed in accordance with the actual thickness of the door to which it is applied, there is a difficulty in lacking versatility.

Further, since the conventional four-axis hidden hinge does not have a means for holding the door in an open state, the door fanned by the wind may unintentionally rotate and close, and the door is opened. When it was necessary to maintain the position, it was necessary to separately install a door opening retainer such as a stay device.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to have general versatility applicable to various doors having different thickness dimensions, and to properly prevent unintentional closing operation of the door. The purpose is to provide a positionable 4-axis hidden hinge.

[0005]

The following is a description with reference to the reference numerals in the accompanying drawings. The 4-door concealed hinge in the door according to the present invention is fixed to the inner surface 1a of the fixed frame body 1 and has a front end portion. The first shaft hole 3 and the second shaft hole 4 are provided in the
Fixed wing plate 5 arranged closer to the inner surface 1a of the fixed frame than
And; fixed to the back surface 6a of the door 6 arranged outside the opening 17 of the fixed frame body 1, and has the third shaft hole 7 and the fourth shaft hole 8 at the tip.
And a rotating blade plate 9 in which the fourth shaft hole 8 is arranged closer to the door back surface 6a than the third shaft hole 7; and a front end portion is fixed by a first fixed pivot 10 passing through the first shaft hole 3. A first connecting plate 12 which is connected to the plate 5 and whose rear end is connected to the rotating blade plate 9 by the first movable pivot 11 passing through the third shaft hole 7 and which is located behind the fixed blade plate 5 when the door is closed. The front end is connected to the fixed blade 5 by the second fixed pivot 13 passing through the second shaft hole 4, and the rear end is connected to the rotating blade 9 by the second movable pivot 14 passing through the fourth shaft hole 8. And the second connecting plate 15.

When the door is closed, the distance between the first movable pivot 11 and the inner surface 1a of the fixed frame is set longer than the distance between the first fixed pivot 10 and the inner surface 1a of the fixed frame 1, and the second movable pivot 14 Is arranged in an intermediate portion between the first movable pivot 11 and the second fixed pivot 13, and the distance of the second movable pivot 14 from the fixed frame inner surface 1a is greater than the distance of the first movable pivot 11 from the fixed frame inner surface 1a. The length is set to be long, and the distance from the fixed frame inner surface 1a of the first movable pivot 11 is set to the fixed frame inner surface 1 of the second fixed pivot 13.
It is set longer than the distance from a.

In addition to the above structure, another four-axis hidden hinge of the present invention is provided with a tension coil spring 16 stretched between the first fixed pivot 10 and the second movable pivot 14, and when the door is open, the second It is set so that the movable pivot 14 is located closer to the inner surface 1a of the fixed frame than the straight line connecting the first fixed pivot 10 and the second fixed pivot 13.

[0008]

In the door closed state, the door 6 is arranged in the inner space of the opening 17 of the fixed frame 1. When the door 6 is opened, the first connecting plate 12 rotates about the first fixed pivot 10 in a direction away from the inner surface 1a of the fixed frame, and the rotary vane 9 makes the first contact about the first movable pivot 11. It rotates with respect to the plate 12 and moves further away from the inner surface 1a of the fixed frame.

At this time, the second connecting plate 15 is the second fixed pivot 1
While rotating 3 in the direction away from the inner surface 1a of the fixed frame, the rotation and rotation of the rotary blade 9 connected by the second movable pivot 14 is guided and regulated. When the front end of the first connecting plate 12 comes into contact with the front end of the second connecting plate 15 and the movement of the movable blade 9 is blocked, the door 6 is opened to the 90 degree position, and the back surface 6a of the door 6 is fixed. It comes to a position facing the outer surface 1b of the frame body 1.

In the 4-axis hidden hinge in which the tension coil spring 16 is provided between the first fixed pivot 10 and the second movable pivot 14, the second movable pivot 14 is fixed with respect to the straight line connecting the first fixed pivot 10 and the second fixed pivot 13. The movable blade 9 is rotationally biased in the closing direction by the elastic force of the tension coil spring 16 while the movable blade 9 is located on the opposite side of the frame inner surface 1a.

The door 6 is operated to open against the bias of the rotation. At the moment when the opening of the door 6 progresses and the second movable pivot 14 crosses the straight line connecting the first fixed pivot 10 and the second fixed pivot 13 to the fixed frame inner surface 1a side, the urging direction of the tension coil spring 16 is changed. Reversely, the movable blade 9 is rotationally biased in the opening direction. Therefore, the door 6 is automatically fully opened to the 90 degree position.

In the application example shown in FIG. 11 and FIG. 12, the mounting recess 2 having a predetermined depth is provided on the inner surface 1a of the fixed frame 1, and the fixed blade 5 is fitted into the recess 2 to fix the fixed frame. It is fixed to 1. Also in the application examples shown in FIGS. 8 and 9,
No mounting recess is provided on the inner surface 1a of the fixed frame body 1.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the fixed blade 5 is a mounting plate portion 1.
8 is fixed to the inner surface 1a of the fixed frame 1 by a screw 20 passing through the through hole 19 and the first connecting plate 12 is provided with a through hole 21 for escape of the head of the screw 20. First shaft hole 3 and second shaft hole 4
