Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a pivot hinge for opening and closing a door, and more specifically to a door that opens and closes with a pivot as a swing center and a building that swingably supports the door. The present invention relates to a pivot hinge for opening and closing a door capable of adjusting a clearance between the pivot hinge and the door mounting portion.

[Conventional technology]

BACKGROUND ART When attaching a door that can perform a swing-type opening / closing operation to a door attachment portion of a building, a hinge mechanism or a pivot hinge is used as a support tool for the door.

[Problems to be solved by the device]

As described above, the conventional door support device swingably suspends and supports the door body on the vertical frame of the door mounting portion of the building facing the swing center side edge of the door body. An integral structure type support mechanism is formed in which the relative position of the part to the vertical frame does not change. For this reason, when installing the door in the building, the door support fixture should be formed so that the minimum gap required for swinging the door is formed between the side edge of the door and the vertical frame of the door mounting portion of the building. It is necessary to adjust the mounting position. Accurately performing this clearance adjustment work is not easy as a practical problem due to the heavy weight of the door and the fact that the work space is often relatively small, and it is not easy to squeak on the door installed in the building. In many cases, inconveniences such as the occurrence of noise and poor opening and closing were caused. Even if the door is installed correctly, the relative position may be different between the door and the door installation part of the building due to aging, and in such a case, the conventional hinge mechanism or pivot hinge may be used. Cannot exert the function of adjusting the mounting dimensions at all.

The main object of the present invention is to provide a pivot hinge for opening and closing a door which can eliminate the above-mentioned inconveniences found in conventional door supporting devices.

[Means for solving the problem]

In view of such an object, the present invention is to insert an eccentric ring having a shaft supporting hole whose center is eccentric with respect to the center of the fitting hole into the fitting hole provided in the base plate, and to provide an inner peripheral surface end of the fitting hole. Part of the eccentric ring is engaged with a plurality of engaging pieces provided on the end of the eccentric ring to engage the eccentric ring in the fitting hole, and the base of the pivot shaft is attached to the base plate. The end of the pivot shaft is locked, and the tip of the pivot shaft is rotatably fitted and supported in the shaft support hole of the eccentric ring in the upper part of the top pivot. While inserting an eccentric ring having a shaft support hole whose center is eccentric to the center,
An arm that meshes and locks an eccentric ring in the fitting hole by meshing a plurality of meshing pieces provided on the end surface of the eccentric ring with a plurality of meshing pieces provided on the inner peripheral surface end portion of the fitting hole. The base end of the pivot shaft is locked to the base plate, the thrust bearing is fitted on the middle part of the pivot shaft, and the tip of the pivot shaft is rotatably fitted and supported in the shaft support hole of the eccentric ring of the arm. The pivot hinge for opening and closing the door, which is made up of a base and is provided with the door suspended between the upper frame of the door mounting portion of the building and the floor frame through the upper part of the top pivot, the lower part of the top pivot, the arm and the base. It is what

[Action]

By disengaging the engagement piece provided on the top pivot upper part and the fitting hole of the arm and the engagement piece provided on the eccentric ring engaged in the fitting hole to displace the eccentric ring, the pivot shaft is moved. It can be supported eccentrically, and the mounting position of the door can be adjusted very easily and at any time as necessary. Therefore, the gap between the door and the door mounting portion of the building can be finely adjusted with high accuracy not only when the door is mounted but also after a long time has passed.
