In the adjustment flag hinge according to the first, second, and third aspects, the movable flag member opens and closes with the upper shaft portion as a fulcrum. The lower shaft portion can be rotated until adjustment of each position is completed, but the concave-convex engagement temporarily locks this rotation.
The lateral movement adjustment of the door is performed by strongly rotating the operation portion of the eccentric shaft using a tool. In accordance with this rotation operation, the convex portion engaged with the concave and convex portions gets over the concave portion and rotates the lower shaft portion. The lower shaft portion and the upper shaft portion are in an eccentric (offset) positional relationship, and the position of the upper shaft portion changes as the lower shaft portion rotates.
When the convex portion that has overcome the concave portion with the rotation of the lower shaft portion falls into the next concave portion, the operation portion that has been lifted by the convex portion at the time of rotation comes into contact with the lower receiving position. It can be known that the rotation has been positioned by the contact sound generated at this time and the touch applied to the operator's hand through the tool. Since the movable flag member opens and closes around the upper shaft portion whose position has changed, the lateral movement of the door closing position has been adjusted.
Two adjustable flag hinges are attached to the door. For this reason, it is possible to adjust the tilt of the door only by laterally adjusting the adjustment flag hinge at the lower position or by adjusting the horizontal position of the adjustment flag hinge at the upper and lower positions. If the relationship between the change in the position of the concave-convex engagement and the door position adjustment amount is set in advance, the door position adjustment operation can be performed quickly and smoothly.
When the nut is operated in one direction using a tool, the nut pushes up the threaded cylindrical member with a seat and moves the door upward together with the eccentric shaft. When the nut is operated in the opposite direction, the door moves downward. After these adjustments are completed, the lower shaft portion is prevented from rotating by using a shaft detent member.

The adjustment flag hinge according to claim 3 is an engagement between the lower shaft portion and the serration tube material or spline tube material in which the rotation stop of the lower shaft portion is inserted into the lower tube portion from below the lower tube portion and stopped. It is done by. When adjusting the lateral movement of the door and adjusting the inclination, the rotation of the serration cylinder or spline cylinder with respect to the lower cylinder is released. When the lateral movement adjustment and the inclination adjustment of the door are finished, the serration cylinder or the spline cylinder is once moved downward to release the engagement. Thereafter, the serration cylinder material or the spline cylinder material is returned to the direction suitable for the rotation prevention, and the rotation prevention is performed again.
The rotation prevention of the lower shaft portion using the serration tube material or the spline tube material does not damage the lower shaft portion and does not require a hole in the lower shaft portion. For this reason, readjustment of the position of a door can be performed without trouble. In addition, since the lower shaft portion can be moved upward, the height of the door can be adjusted only by rotating the nut.

The adjustment flag hinge according to claim 4 has a structure in which the adjustment flag hinge according to claim 1 is inverted up and down. The adjustment flag hinge of claim 5 has a structure in which the adjustment flag hinge of claim 2 is inverted up and down. The adjustment flag hinge according to claim 6 has a structure in which the adjustment flag hinge according to claim 3 is inverted up and down.
For this reason, in the adjustment flag hinge according to the fourth, fifth, and sixth aspects, the movable flag member attached with the door opens and closes together with the eccentric shaft and the lower shaft portion as a fulcrum. When the nut is rotated in one direction, the nut moves upward along the threaded cylindrical portion of the seated threaded tubular member, pushes up the seated tubular member attached to the lower end of the upper tubular portion, Move the door upward.
The disengagement of the serration tubular member or spline tubular member according to claim 6 and the upper shaft portion temporarily moves the serration tubular member or spline tubular member in the upper tubular portion upward.
The serration tubular member or spline tubular member according to claim 3 or 6 has a length that reaches the opening end of the lower tubular portion and the upper tubular portion, or the lower tubular portion, in order to facilitate operation in the temporary pulling direction. It is desired that the length protrudes from the opening end of the upper portion and the upper tube portion.

  The adjustment flag hinge according to the present invention is a door in which the rotational position of the eccentric shaft is positioned by providing an uneven engagement portion between the threaded cylinder member with a seat on the fixed side and the operation portion on the rotation side. The lateral movement of the mounting position can be adjusted, and the height of the eccentric shaft receiving the movable flag member can be adjusted by rotating the nut. As a result, accurate positioning of the door can be performed smoothly. Since the eccentric shaft is supported on the lower cylinder portion of the fixed flag member, the movable flag member can be stably supported, and the eccentric shaft is not rotated when the height is adjusted.
