Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pivot hinge, and more particularly to a pivot hinge capable of adjusting a hanging position of an upper portion of a door with respect to a door frame.

[Conventional technology]

As a means for adjusting the hanging position of the door in the pivot hinge in a direction substantially orthogonal to the door, the connecting member on the door or door frame side is moved within the play of the long hole, or the connecting member of the board to which it is attached. It is moved within the play of the slot.

[Problems to be Solved by the Invention]

The adjustment work of the connecting member is troublesome in order to move the connecting member within the range of the long hole of the connecting member and the mounting portion and fix the connecting member in a predetermined position with a screw or a bolt nut.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a work that facilitates the work of adjusting the hanging position of a door in a direction substantially orthogonal to the door.

[Means for Solving the Problems]

In order to achieve the above object, in a door-side first connecting member that pivotally attaches upper portions of a door and a door frame to each other, a fixed arm fixed to the upper portion of the door and a movable arm pivotally attached to the fixed arm are opened. It is configured to adjust the relative position of the longitudinal axis supported by the movable arm or the door and the door frame at an angle.

The relative rotation of the movable frame and the fixed frame is preferably performed by a first adjustment screw that blocks rotation of the movable frame in the closing direction and a second adjustment screw that blocks rotation of the movable frame in the opening direction.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The door (1) has its upper end at the first connecting member (2) on the upper side of the door, the second connecting member (3) at the upper side of the door frame and the vertical axis (4), and the lower end at the lower part of the door (1). The third connecting member (5) on the side, the fourth connecting member (6) on the lower side of the door frame, and the vertical axis (7) are pivotally attached to the door frame (8). The connecting members (2), (3), (5), and (6) are of a take-out type in which the vertical axes (4) and (7) protrude from the door (1).

The first connecting member (2) comprises a fixed arm (9) and a movable arm (11) pivotally attached to the arm by a longitudinal pin (10) at each end.
