BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can open a pivoting door in furniture or a pivoting door in a building by 90 ° or more with respect to a fixed body such as a furniture body or a building. The present invention relates to the improvement of the hinge device.

[0002]

2. Description of the Related Art When horizontally attaching a door to a furniture such as a locker or a cabinet through a hinge device so that the opened door does not interfere with people's walking or putting things in or out of the furniture, It is being done that the door can be opened wide up to about 180 °.

As a prior art of the conventional hinge device for enabling the door to be opened up to about 180 ° as described above, Japanese Patent Laid-Open No. 49-75967 and Japanese Utility Model Publication 59-1.
There is one disclosed in Japanese Patent No. 0301. In the former case, a straight long hole long in the depth direction of the cabinet and an arcuate long hole in the front position are bored in the mounting plate mounted on the inner surface of the cabinet body, and the base end is pinned to the back side of the mounting plate. An arc-shaped guide groove is provided on the pivotally mounted arm, the guide groove and the linear elongated hole are connected by a first movable shaft, and the tip of the arm and the proximal end of the linear rod are pivotally attached by a pin.
The tip of this straight rod is pivotally attached to the inner surface of the door. A middle portion of a bending rod whose tip is pivotally attached to a portion near the center of rotation of the door is movably connected to the arcuate elongated hole via a second movable shaft, while the base end of the bending rod is connected to the first portion. It is rotatably connected to a movable shaft.

On the other hand, the latter is composed of three link bodies, and the base end of the first link body is movable back and forth and rotatable with respect to the furniture main body along the depth direction of the furniture main body. On the other hand, the tip of the first link body is pivotally attached to the door, and the one end of the second link body is pivotally attached to the furniture body while the middle portion between the one end and the other end of the second link body is attached. Is pivotally attached to a middle portion between one end and the other end of the first link body, and one end of the third link body is pivotally attached to the other end of the second link body, while The other end is pivotally attached to the door.

[0005]

However, in the former case, the linear rod is attached to the inner surface of the door via the arm pivotally attached to the mounting plate so as to rotate the arm and the inner surface of the mounting plate. There is a problem that a large space is required between the linear rod and the door and the door cannot be opened 90 degrees or more with respect to the opening surface.

Further, in the latter case, although the base end of the first link body linearly moves back and forth along the inner surface of the mounting plate, the tip end side of the first link body swings in response to the rotation of the door. Move. Since the second link body and the third link body respectively rotate, a large space is required for the rotation as a whole. In summary, in these prior arts, depending on the opening and closing movements of the door, a considerable amount of space has to be taken up by the pivoting parts of the hinge device, which may lead to an opening in the opening obstructed by the door of furniture such as cabinets. There is a problem that an effective volume (a volume capable of accommodating articles) of the volume is reduced because the hinge device is attached.

Further, in the latter case, since the three link bodies rotate in different directions to open and close the door, the first link body and the second and third link bodies interlocked with the first link body are twisted. There is a problem that it is easy to occur and the door cannot be opened and closed smoothly. The present invention aims to provide a hinge device that solves these problems.

[0008]

In order to achieve this object, the present invention is a hinge device for opening and closing a door to an opening in a fixed body such as a furniture body. The first slide body and the second slide body are positioned in parallel with respect to the inner surface of the mounting plate fixed to the base plate, and the two slide bodies can be moved back and forth only in a straight line along the depth direction of the fixed body. The interlocking mechanism is mounted between the mounting plate and the first slide body and the second slide body so that the first slide body is simultaneously advanced and retracted at a faster speed than the second slide body. On the other hand, one of the slide bodies is provided with a pivotal attachment portion for the door at the tip of one of the slide bodies, and the tip of the other slide body is formed at the tip of the other slide body according to the difference in advancing and retracting speeds of the slide bodies. , Lock the door Serial is provided with a guide means so as to rotate about the pivot point at one of the slide body.

[0009]

In this configuration, when the door is pulled toward you, the interlocking mechanism provided between the mounting plate, the first slide body and the second slide body, and the two slide bodies function as the mounting plate. Since the first slide body is mounted so as to advance and retreat only linearly in the inward direction with respect to the inner surface, the first slide body moves linearly in the outward direction of the fixed body at a faster speed than the second slide body. At the same time, since the locking portion of the door rotates around the pivotal attachment portion at the tip of one of the slide bodies, the door as a whole rotates while moving away from the fixed body, and therefore the door should be opened greatly. You can

Further, according to the present invention, as a space for attaching the hinge device to a fixed body such as a furniture body,
It is sufficient if there is a narrow space that allows the linear movement of both slides with respect to the mounting plate, and the effect that the article storage volume in the opening is not restricted. Further, since the interlocking mechanism merely moves the first slide body and the second slide body back and forth in the same direction at different speeds, an unnecessary moment does not act on the interlocking mechanism and both slide bodies, so that both slide bodies are moved. Since it is possible to ensure the operation of the smooth linear movement of, the door can be opened and closed smoothly.
