[0003]

However, the mounting of the above-mentioned handle usually requires the opening of the door and the work of mounting the handle separately from the mounting of the hinge. There was a problem in terms of workability and cost. On the other hand, according to the above-described conventional door hinge, when the door is closed, a fixed angle (about 18 when the door is fully opened) is used.
At 0 °), the connecting side that was open was closed, and there was a risk that the finger would be caught in that part.

On the other hand, there are door hinges in which the mounting and swinging portion of the door is formed of an extruded molded product, thereby simplifying the mechanism and improving the workability and the safety of the mounting portion. Japanese Unexamined Patent Publication No. Hei 8-105264, etc.), since a bent door in which a plurality of doors are swingably connected to each other is not premised, the workability of attaching the above-described handles and the finger claws between the doors are improved. There is no technical idea to do so.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a door hinge and a door hinge, which do not require a handle to be attached and are excellent in terms of workability and cost. It is to provide a door structure using the same.

[0006]

A feature of the door hinge according to the present invention for achieving the above object is to operate the door in a door hinge for connecting a plurality of doors to each other so as to be swingable. The point is that a handle is provided. The portion where the handle portion is provided may be any movable portion such as a door mounting portion in addition to the swing shaft. Here, the “door” is a broad concept including so-called doors such as storage doors, bathroom doors, and kitchen doors, as well as those having the same functions as doors such as partition panels.

[0007] The present invention further comprises a hinge body, and a door mounting member swingably connected to both sides of the hinge body, and a handle portion for operating the door is provided on the hinge body. It is preferable from the operation and effect described below.

When the second contact guide portion is provided separately on the hinge main body and the door mounting member and fitted to each other, the hinge main body and the door mounting member are easily swingably connected only by fitting. The members for connection (for example, pivot pins) are not particularly required, and the number of parts can be reduced. In addition, since the cross section can be made to have a constant shape, it can be extruded and thus can be manufactured easily.

On the other hand, according to the door structure of the present invention, since the door hinge of the present invention as described above is used, there is no need to attach a handle, which is excellent in workability and cost, and preferably when the door is opened and closed. It is possible to provide a door structure that has less danger of finger claws and the like and is also excellent in design. In addition, since the door mounting portion of the door hinge is formed integrally with the door itself, labor such as fixing the door mounting member to the door can be omitted, and the construction becomes easier.
