[Detailed description of the device]

[0001]

[Industrial application]

 According to the present invention, by combining the cam plate and the link assembly member, the door can be opened and closed within a range of 180 ° and can be opened to the closest distance to the door of the adjacent furniture, and at the same time, the hinge itself. It is related to the hidden hinge of the door in furniture, etc., where the door is not projected outside.

[0002]

[Prior Art]

 Conventionally, the opening of the door was limited by the door of the adjacent furniture, and as a solution to the inconvenience that it could not be opened sufficiently, it was provided at the doorway of the furniture body so that it could move in the front-back direction and A door holding member having a hinged door and a pivotally mounted member that is pivotally attached to the door holding member in conjunction with opening and closing of the door. There is known a door hinge device for furniture including a drive member configured to drive the above-mentioned door holding member (see Japanese Patent Laid-Open No. 60-219379).

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, a door holding member having a complicated structure and a driving member (for example, a pulley, a belt, a rack, a pinion, etc.) for driving the door holding member are required, and further, opening and closing of the door is required. Since the support shaft that supports the vehicle, which replaces the hinge, supports the entire door, there is a problem in terms of strength as a support shaft that can be used in a limited space. There was a problem that it could not be opened to a close range. In view of this point, the present invention has a simple structure, and by combining a cam plate with a link assembly member made of a plate material that is also strong in strength, it is possible to open and close the door smoothly and obtain a sufficient opening degree. The purpose is to provide a hidden hinge for the door in furniture.

[0004]

[Means for Solving the Problems] The present invention is intended to solve the above problems, and in a hidden hinge of a door in furniture or the like, a base plate is fixed at an appropriate position on the opening side of the furniture body. A cam plate is fixed to one end of the door, and the base plate and the cam plate are connected by a link assembly member made of a plate material. As the link assembly member, the first plate is the first caulking shaft and the first arm is the first arm. And the second arm is attached by the second caulking shaft, and the other end of the first arm and the end of the substantially Z-shaped first lever are pivotally attached by the third caulking shaft. The end portion and the middle portion of the first lever are pivotally attached by the seventh caulking shaft, and further, one end portion of the substantially Z-shaped second lever is pivotally attached by the fourth caulking shaft to the middle portion of the second arm. The other end of the 1 lever has one end of the third arm and the fifth cover. In addition to being pivotally attached by a female shaft, a pin is provided so as to engage with the cam groove of the cam plate, and the other end of the second lever, the other end of the third arm, and the end of the cam plate are connected to each other by the sixth caulking. We adopted the technical means of forming by pivoting on a shaft.

[0005]

[Action]

 By adopting the above technical means, the present invention enables the door to be propelled forward while rotating in response to opening and closing of the door by the link assembly member, and further along the cam groove of the cam plate. By moving the pin, the door can be opened at the closest distance to the front of the adjacent furniture, and the operation can be performed continuously, allowing smooth opening and closing operations.
