Description

  The present invention relates to an opening device provided in an opening of a building, and more particularly to an opening device provided with a pivot hinge.

  Among the opening devices provided in the building opening, there is a device that uses a so-called pivot hinge, and the door of the opening device can be opened and closed in a swinging manner using this as a shaft. Here, the pivot hinge is usually brought close to one vertical frame side of the opening device, and one pivot hinge is provided on each of the upper and lower portions of the opening device.

  The pivot hinge includes a pivot shaft side member having a pivot shaft extending in a direction parallel to the vertical direction of the opening device, and a bearing side member having a bearing for receiving the pivot shaft. As a pair, it plays the role of a hinge. One of the pair of members functions as a rotation axis of the door body by fixing one of the members to the frame of the opening device and the other to the door body.

  Thus, since the pivot hinge has a structure for connecting the pivot shaft and the bearing, it is necessary to finely adjust the relative position relationship between the pivot shaft and the bearing each time the opening device is installed. And since this fine adjustment is an adjustment performed in three dimensions including the width direction, the thickness direction, and the height direction of the door, it has been difficult to determine the position. Also, it took a lot of time to make adjustments.

  Patent Documents 1 to 3 disclose the structure of a pivot hinge for facilitating such fine adjustment. These pivot hinges are provided with a pivot shaft or a bearing on a member that swings by operation, or by providing a pivot shaft or a bearing eccentrically on a rotating member so that the pivot shaft or the bearing is placed in a horizontal plane. It is comprised so that it can be moved within.
