JP 2008-179945 A

In the conventional hinged door described above, the pivot hinge is provided in the middle of the out-of-plane direction (thickness direction) of the door body. It strongly contacts the airtight material attached to the airtight material, and the airtight material is worn early.
Therefore, the present applicant sets the airtight material attached to the hanging vertical frame to the inner side in the in-plane direction than the center of rotation of the door body in the out-of-plane direction (axial center of the pivot hinge), and the door body is in the out-of-plane direction. When the door is turned, the door does not come into strong contact with the airtight material attached to the hanging vertical frame, and when the door is in the closed position, one side surface of the door in the out-of-plane direction becomes the airtight material. It was proposed that the airtight material should not be worn early by contact.

  By doing as described above, early wear of the airtight material attached to the hanging vertical frame can be prevented, but by shifting the position of the airtight material inward in the in-plane direction as described above, the door body When the door is in the open position, the end surface on the hanging side of the door is concealed by the airtight material and the airtight material mounting part of the hanging frame, so that the airtight material and the hanging material vertical The part where the airtight material is attached gets in the way, making it difficult to operate the pivot hinge.

That is, the pivot hinge can be moved up and down and out of the plane for installation and removal of the door, adjustment of the installation of the door, etc. When the pivot hinge is attached to the door, The shaft can be moved in the vertical direction and the out-of-plane direction by rotating a screw or the like with a tool from the end surface on the suspending side of the door body.
Because of this, when adjusting the installation, installation and removal of the door by rotating the aforementioned screw with the door as the open position, the airtight material and the airtight material mounting part of the hanging vertical frame as described above It becomes very difficult to operate the pivot hinge.

  The object of the present invention is to prevent the suspension side airtight material attached to the suspension vertical frame from being worn out early by the door body when the door body is rotated in the out-of-plane direction, and to attach and remove the door body. It is to make the hinged door so that the pivot hinge can be easily operated when the door body is installed or adjusted.

In the present invention, the door suspension side is attached to the door frame by a pivot hinge so as to be pivotable in the out-of-plane direction between the closed position and the open position, and the pivot hinge is operated from the end surface of the door suspension side. The doors can be attached, removed, and adjusted for installation.
The hanging vertical frame of the door frame has a frame main body and an attachment detachably attached to the frame main body, the attachment being closer to one side in the out-of-plane direction than the door body, It protrudes to the inner side in the in-plane direction from the direction rotation center,
A suspension-side airtight material is placed near the projecting end of the attachment, toward the side surface in the out-of-plane direction of the door body, and the door body contacts in the closed position of the door body and in the vicinity of the closed position. The hinged door is mounted so that the door does not come into contact when rotating outward.

In the present invention, when the door body rotates in the out-of-plane direction around the pivot hinge, the in-plane direction side surface of the door body and the corner portion of the suspension side end surface move along the locus,
The suspension side airtight material is located on the opposite side of the trajectory center of the door body in the out-of-plane direction with respect to the locus, and when the door body is in the closed position, one side surface in the out-of-plane direction of the door body can be in contact. .
In this way, when the door rotates between the closed position close to the closed position and the open position, the corner portion of the door does not touch the hanging side airtight material. Premature wear due to airtight doors can be prevented.

In the present invention, the attachment has an attachment portion, an inward portion that extends inward in the in-plane direction from the attachment portion, and a recess for mounting an airtight material provided at an inner end portion in the surface direction of the inward portion,
By attaching the attachment portion to the inner side surface in the in-plane direction of the frame main body detachably with fixing means, the concave portion is positioned in the in-plane direction inner side than the rotation center in the out-of-plane direction of the door body,
A suspension side airtight material can be attached to the recess.
