DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concealed hinge for foldably connecting doors and doors to each other or to a mounting portion thereof (a door frame or the like). The present invention relates to a recombination type in which a function of adjusting a position can be selectively added.

[0002]

2. Description of the Related Art When a hidden hinge is used, for example, in a folding door, the presence of the hinge can be hidden from both inside and outside of the partition space when the door is closed. It has the advantage of not impairing the appearance of the space.

A concealed hinge of this kind has a basic structure in which an arm or a link rotatably supported at one end is arranged crosswise and the other end is mutually inserted into the other casing. Specifically, a substantially "-" shaped link member is rotatably supported at one end of a casing embedded and fixed at an end face of a door or the like so as to be rotatable at one end, and the other end is inserted in the other casing in an intersecting manner. There is a known type in which an intersecting portion is rotatably supported at the intersection and the other end is connected to the other end of a link whose one end is supported by the other casing (Japanese Patent Laid-Open No. 2-240384). Publications etc.).

[0004]

By the way, generally, when a hinge is attached to a door or the like, the attachment position mainly in the vertical direction often shifts somewhat. If the mounting position of the hinge is shifted, the mounting position of the door or the like in the vertical direction is inevitably shifted. Therefore, conventionally, various hinges have been proposed in which the mounting position of a door or the like can be adjusted in the vertical direction (for example, see Japanese Utility Model Publication No. 4-9416).

The inventor of the present application has attempted to add the above-described position adjusting function to the above-mentioned hidden hinge. However, the hidden hinge is, for example, a part which may be slightly displaced vertically, for example. The vertical position adjustment means is not required because it is used for the lower door member to which it is attached, such as one that is provided at a lower cost (one without the vertical position adjustment means), for example, one used in the door of a folding door It is necessary to be able to adjust the position in the vertical direction individually (with means for adjusting the vertical position on both sides), such as those used between the door and the door frame, so that the vertical position can be adjusted only on one side It has been found that there is a need to prepare three types of products, which require means (one with a one-side vertical position adjusting means).

Conventionally, when a plurality of types of hinges are required as described above, they are individually designed and assembled, and sharing of parts is limited to general-purpose articles such as screws. Particularly, in the case of the hidden hinge, the mechanism is complicated, so that a position adjusting means can be selectively added to the hidden hinge, and a special device is required to share the main parts. There is no one that can share the main parts among the three types of hidden hinges.

[0007] In view of the above, the present invention enables a selective addition of a position adjusting means and a common type of common component to reduce the production cost so as to suppress the production cost. And a method for producing the same.

[0008]

In order to achieve the above-mentioned object, a hidden hinge according to the present invention uses a link mechanism comprising a pair of link members on the left and right as a common unit, and a door door is provided on each of the left and right link members. It is obtained by selectively assembling the following two types of casings A and B embedded in the end surfaces of the above-mentioned components. And the casing A is
A pivot portion is formed at one end side of each of the left and right link members, but does not include a position adjusting means, and the casing B includes a casing main body and a position adjusting member assembled to the mounting portion of the casing main body. The position adjusting member is formed with a pivot portion at one end of each of the left and right link members so that position adjustment can be performed between the position adjusting member and the casing body. Things.

As a preferred embodiment of the hidden hinge of the present invention, a catch mechanism having a common specification is incorporated in each of the casing A and the casing B. If at least one of the casing A and the casing B is turned upside down, the left and right sides are turned over. One that can be replaced between link members, and the like.

Further, in the method of manufacturing a hidden hinge according to the present invention, the link mechanism comprising a pair of right and left link members is used as a common unit, and the left and right link members are respectively fixed to doors or the like. Types of casings A and B
Are selectively combined and pin-coupled to obtain three types of hidden hinges including the casing A and the casing A, the casing B and the casing B, and the casing A and the casing B.

[0011]

In the concealed hinge according to the present invention constructed as described above, a link mechanism is used as a common unit, and a casing A having no vertical position adjusting means and a casing B having vertical position adjusting means are provided. Since they can be selectively assembled, the three required hidden hinges are each manufactured on demand. At the time of manufacture, either casing A or B is incorporated into the pivot portion of the link member and is pin-connected.

Further, the casing A and the casing B
By incorporating a catch mechanism with a common specification that maintains the open / closed state with a door opening force within a certain range, even if the opening and closing direction of the door etc. is suppressed and the proper opening and closing posture is maintained, Parts can be shared.

Further, the casing A and the casing B are
