Abstract

PURPOSE: To make it possible to provide general purpose properties which are applicable to various types of doors whose thickness dimensions are different from each other and inhibit precisely an unintentional closing motion of the doors as well. CONSTITUTION: A fixed blade plate 5 is connected to a movable blade plate 9 with a first connection plate 12 and a second connection plate 15. Where a door is in a closed state, the spacing of a fixed frame 1 on a first movable axis 11 from the inner side surface is set to be identical to that of the fixed frame 1 on a first fixed axis from the inner side surface. The second movable axis 14 is laid out at the middle part between the first movable axis 11 and the fixed axis 13. The spacing of the second movable axis 14 from the inner surface of the fixing frame is set to be larger than the spacing of the second fixing axis 13 from the inner surface 1a of the fixing frame. A tensile coil spring 16 stretchedly installed between the first fixing axis 10 and the second movable axis 14 is installed. When the door is in an open state, the second movable axis 14 is set so that it may be located close to the inner surface 1a of the fixing frame than a straight line which connects the first fixing axis 10 to the second fixing axis 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concealed hinge of a four-axis type in which a door is arranged outside 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 prevent the unintentional closing operation of the door accurately. The purpose is to provide a positionable 4-axis hidden hinge.

[0005]

The four-axis concealed hinge of the present invention is fixed to the inner surface 1a of the fixed frame 1 and has the first shaft at the tip thereof. A fixed blade 5 provided with a hole 3 and a second shaft hole 4, and the first shaft hole 3 is arranged closer to the inner surface 1a of the fixed frame than the second shaft hole 4; It is fixed to the back surface 6a of the door 6 arranged on the outer side, the third shaft hole 7 and the fourth shaft hole 8 are provided at the tip end, and the fourth shaft hole 8 is closer to the door back surface 6a than the third shaft hole 7. And the rotating vane plate 9 arranged as follows; the first fixed pivot 10 passing through the first shaft hole 3
The front end is connected to the fixed blade 5 by, and the rear end is connected to the rotating blade 9 by the first movable pivot 11 passing through the third shaft hole 7, and is located behind the fixed blade 5 when the door is closed. First
A connecting plate 12; a front end portion thereof is connected to the fixed blade plate 5 by a second fixed pivot shaft 13 passing through the second shaft hole 4, and a rear end portion thereof is rotatable by a second movable pivot shaft 14 passing through the fourth shaft hole 8. 9 and a second connecting plate 15 connected thereto.

In the door closed state, the distance from the inner side surface 1a of the fixed frame 1 of the first movable pivot 11 is set to be substantially the same as the distance from the inner side surface 1a of the fixed frame 1 of the first fixed pivot 10.
The second movable pivot 14 is replaced with the first movable pivot 11 and the second fixed pivot 1.
3, the distance between the second movable pivot 14 and the fixed frame inner surface 1a of the second movable pivot 14 is set to the fixed frame inner surface 1a of the second fixed pivot 13.
Set larger than the distance from.

In addition to the above structure, another four-axis concealed 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 outer 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 FIGS. 8 and 9, a 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 example shown in FIGS. 10 and 11, the mounting concave portion 2 is provided in the inner surface 1a of the fixed frame body 1 and the fixed blade 5 is fitted in the concave portion 2. Also, the depth dimension of the concave portion 2 is set deep, and the rear surface 6a of the door 6 is closer to the rough surface of the fixed frame 1 and the surface 1b in the opened state.

Also in the application examples shown in FIGS. 12 and 13, the mounting recess 2 is provided in the inner surface 1a of the fixed frame 1,
The fixed blade 5 is fitted in the recess 2, but the depth of the recess 2 is set to be shallower than that of the above two application examples.
The thickness of the door 6 is small. Also in the application examples shown in FIGS. 14 and 15, the mounting recess is not provided in the inner surface 1a of the fixed frame body 1, and the thickness dimension of the door 6 is smaller than that in each of the application examples.
