Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hidden hinge that foldably connects a door, a door, or the like, or a mounting portion thereof (door frame, etc.), and more specifically, a door or the like. The present invention relates to a recombinant type in which a position-adjustable function 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 the partition space when the door is closed. It has the advantage of not impairing the appearance of the space.

This type of hidden hinge has a basic structure in which arms or links rotatably supported at one end are arranged in a cross manner, and the other ends enter into the other casing. Specifically, a substantially U-shaped link member is rotatably supported at one end in a casing fixedly embedded in the end face of the door, etc., and the other end enters the other casing. It is known that a crossing portion is rotatably supported 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. 240240/1990). Publication, etc.)

[0004]

By the way, in general, when a hinge is attached to a door or the like, the attachment position in the up-down direction often shifts to some extent. If the hinge is installed at a different position, the vertical installation position of the door will inevitably be displaced. 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 (see, for example, Japanese Utility Model Publication No. 4-9416).

The inventor of the present application has attempted to add the position adjusting function as described above to the above-mentioned hidden hinge. However, as the hidden hinge, at least, for example, a portion in which vertical displacement may occur. The vertical position adjusting means is not required, and it is desired to provide it at a lower cost (the one without the vertical position adjusting means), for example, the one used for the doors of folding doors. Vertical position adjustment on one side only, such as those that need to be able to adjust the vertical position individually (equipped with both-side vertical position adjustment means), for example used between the door and the door frame We have found that there is a demand to prepare three types of products, one that requires a means (one that has a vertical position adjustment means on one side).

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. In particular, since the hidden hinge has a complicated mechanical part, it is necessary to add a position adjusting means selectively to the hidden hinge, and special measures are required to make the main parts common. There is no one that allows commonization of major parts among the three types of hidden hinges.

In view of the above point, the present invention is a recombinant hidden hinge which is capable of selectively adding the position adjusting means, and can reduce the production cost by sharing the main parts. And its manufacturing method.

[0008]

In order to achieve the above-mentioned object, a hidden hinge according to the present invention has a link mechanism composed of a pair of left and right link members as a common unit, and each of the left and right link members has a door door. It is obtained by selectively assembling the following two types of casings A and B which are embedded in the end faces of the above. And the casing A is
Although a pivotally-attached portion is formed on one end side of each of the left and right link members, no position adjusting means is provided, and the casing B is divided into a casing main body and a position adjusting member assembled thereto, The position adjusting member is formed with a pivotal attachment portion at one end of each of the left and right link members, and is configured so that position adjustment can be performed between the position adjusting member and the casing body.

As a preferred embodiment of the hidden hinge of the present invention, a casing A and a casing B each having a catch mechanism of a common specification are incorporated, and at least one of the casing A and the casing B is left and right when inverted upside down. The link members can be replaced with each other, and the like.

Further, in the method for manufacturing the hidden hinge according to the present invention, the above-mentioned two methods of fixing the door mechanism and the like to the left and right link members using a link mechanism composed of a pair of left and right link members as a common unit. Type of casing A, B
Is selectively combined and pin-connected to obtain three kinds 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, the link mechanism is used as a common unit, and the casing A having no position adjusting means such as up and down and the casing B having position adjusting means such as up and down. As they can be assembled selectively, the required three types of hidden hinges are manufactured on demand. At the time of manufacture, either casing A or B is incorporated in the pivotal attachment portion of the link member and pin-connected.

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

Further, the casing A and the casing B are
By turning upside down so that the left and right link members can be attached to each other, parts management becomes easier, and two types of hidden hinges, a left-opening door and a right-opening door, are composed of the same part. This also makes it possible to standardize parts.
