[Prior art]

 Conventionally, in order to rotatably attach a door to a door frame or the like, a hinge composed of two blade plates rotatably attached to an axial core is used. The blades were fixed to the door with screws, etc.

However, since the door frame to which the door is attached is constructed by on-site work and the door is often an off-the-shelf item, it is rarely always installed in an ideal state. It is common to do some rework.

According to the conventional mounting method, when the door is not mounted in a good condition on the door frame or the like, the blade plate is removed from either the door or the door frame, the position of the door is adjusted, and then the blade is adjusted again. I was wearing a board. This not only makes the work very complicated, but sometimes there is a situation in which there is a screw hole in the front of the door or door frame and the vane plate cannot be attached again.

In order to solve this problem, an adjusting hinge having a function of adjusting the mounting position in the left-right direction of the door (that is, the thickness direction of the door) and the vertical direction of the door (that is, the height direction of the door) is provided. Various proposals have been made. For example, Japanese Utility Model Laid-Open No. 62-16672 and Japanese Patent Application Laid-Open No. 3-187486.

The invention of Japanese Utility Model Laid-Open No. 62-16672 is a hinge having vertical / horizontal adjusting means, in which one vane plate is attached to a seat plate, and a gap between the seat plate and the vane plate is adjusted by a screw member. The door can be adjusted left and right by adjusting the amount of screwing, and by rotating the shaft pin up and down and the other blade plate up and down with the thigh screws attached to the upper and lower ends of the upper and lower bearings, Adjusting vertically.

The invention of Japanese Patent Laid-Open No. 3-187486 is a door hinge having vertical / horizontal adjusting means similar to the above invention, in which one vane plate is attached to an adjusting base having a projecting wall at the center in the vertical direction. Then, adjust the tilt of the blade to adjust the door to the left and right, and move the female screw body fitted to the hinge shaft up and down to move the other blade up and down to adjust the door up and down. There is.
