Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window hinge for rotatably connecting a movable shoji such as a push-up window to a fixed side.

[0002]

2. Description of the Related Art A push-up window is a window frame in which the upper part of a movable shoji is connected by a hinge so as to be rotatable in an out-of-plane direction.
As this hinge, a hinge in which a first member and a second member are rotatably connected by a shaft is generally used. The first member is fixed to a window frame, and the second member is fixed to an upper part of a movable shoji. The movable shoji is rotatable about the axis in the out-of-plane direction.

[0003]

With such a hinge, since the second member rotates about the axis with respect to the first member, when the movable shoji is opened when the window is a push-up window, the movable shoji will not move. Since the upper part rotates while moving above the shaft, the upper part of the movable shoji may interfere with the window frame.

Therefore, in order to greatly open the movable shoji, it is necessary to increase the vertical dimension between the upper part of the movable shoji and the window frame when the movable shoji is closed. Not only is the seal between and uncertain, but when the movable shoji is closed, a large gap is created between the upper part of the movable shoji and the window frame, resulting in poor appearance.

Therefore, an object of the present invention is to provide a window hinge capable of solving the above problems.

[0006]

Means for Solving the Problems First fixed to a fixed side
The longitudinal direction ends of the first link 13 are rotatably connected in the out-of-plane direction across the bracket 11 and the second bracket 12 fixed to the movable shoji 1, and the first link 13
The second link 16 is rotatably connected in the out-of-plane direction to an intermediate portion in the longitudinal direction of the third link 18, and the third link 18 is connected to one end of the second link 16 in the out-of-plane direction so as to be rotatable in the out-of-plane direction. 1
A fourth link 19 rotatably connected to the bracket 11 in the out-of-plane direction and connected to the other end of the second link 16 in the longitudinal direction rotatably in the out-of-plane direction is connected to the second bracket 12 in the out-of-plane direction. When the movable shoji 1 is in a closed state, the first link 13 does not rotate in the out-of-plane direction indoor side, and the second link 16 faces in the out-of-plane direction. The third and fourth links 18, 19 in a substantially horizontal position
The hinge for the window that makes the posture almost vertical.

First bracket 50 fixed to the fixed side
And a second bracket 51 fixed to the movable shoji 1, and first and second rotatably connected at a longitudinal intermediate portion.
Links 52 and 53 are provided, and one longitudinal end of the first link 52 is connected to the first bracket 50 so as to be slidable in the out-of-plane direction and rotatable in the out-of-plane direction. The other end is rotatably connected to the second bracket 51 in the out-of-plane direction, and the one longitudinal end of the second link 53 is rotatably connected to the first bracket 50 in the out-of-plane direction. The other end of the link 53 in the longitudinal direction is connected to the second bracket 51 so as to be slidable in the vertical direction and rotatable in the out-of-plane direction, and when the movable shoji 1 is closed, the first link 52
Is a window hinge in which the second link 53 does not slide downward relative to the first bracket 50, and the second link 53 does not slide downward relative to the first bracket 50.

[0008]

[Operation] If it is the first window hinge, the fourth link 1
9 moves the second link 16 in the out-of-plane direction, and
Since the movement of the link 16 is restricted by the third link 18 to rotate the first link 13 in the out-of-plane direction, the second bracket 12
Moves upward relative to the first bracket 11 while moving downward and out-of-plane. Therefore, when the movable shoji 1 is opened, the upper part of the movable shoji rotates upward and downward and downward.

In the case of the second window hinge, the first link 5
The second bracket 53 moves in the first bracket 50 because the second link 53 moves in the out-of-plane direction and the connecting portion of the first and second links 52, 53 moves downward due to the movement of the second bracket in the out-of-plane direction. On the other hand, since the movable sliding door 1 is opened upward while moving in the downward and out-of-plane directions, the upper portion of the movable sliding door moves upward while moving in the downward and out-of-plane directions when the movable sliding door 1 is opened.
