[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge having a function of adjusting a mounting position of a mounted door or the like up and down.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made for a hinge of this type.
There is an official gazette. In this proposal, a flange protruding from the center of the shaft pin is brought into contact with the lower end of the pipe of one of the upper wing plates, and is fixed to the lower end of the pipe of the other lower wing plate. With a pot screw that is screwed to the collar member, the shaft pin is moved up and down, and one of the blades is moved up and down through the flange, so that the mounting position of the door attached to the blade is adjusted up and down. is there.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned proposed hinge, since a load such as a door is constantly applied to the collar member through a tube, a flange, a shaft pin, and a potato screw, the collar member is not provided. However, since it is difficult to fix a collar member to a relatively thin-walled pipe by welding or the like in practice, it is necessary to use a considerable technique. Although the member and the pipe are fixed by spot welding, etc., the mechanical strength is insufficient with spot welding.) Sufficient mechanical strength cannot be obtained, and there is a risk of failure during use. , Especially for heavy doors.

In this hinge, since the upper end of the shaft pin is in direct contact with the lower end of the collar member fixed to the upper end of the pipe of one of the blades, the one of the hinges is rotated by opening and closing a door or the like. The contact resistance between the collar member and the shaft pin is large,
There is also a disadvantage that the opening and closing of doors and the like become heavy and the doors do not go smoothly.

In this hinge, when the pipe portion of one blade plate is adjusted upward, the space between the flange portion and the tube portion of the other blade plate is exposed, so that dust may adhere to the exposed shaft pin. Alternatively, there is a drawback that dust may enter between the shaft pin and the other pipe portion and cause a trouble that hinders smooth opening and closing of a door or the like.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and an adjusting screw for attaching to a lower tube portion is mounted on the lower tube portion. The object of the present invention is to solve the above-mentioned problems by screwing onto an adjusting ring, attaching a cover to the lower part of the pipe located above and providing a hinge equipped with a ball for bearing at the upper end of the shaft core. I have.

In the present invention, the left and upper tubes are formed by bending the upper and lower halves of the left and right halves, respectively, and are provided with lower and upper notches at required locations. An adjustment plate in which an adjustment screw is screwed into the lower cutout, in which the right blade is rotatably held by being inserted into the lower and upper tube portions by a core rod holding a ball rotatably at the upper end. A hinge, wherein a washer locked with an upper cap is inserted into the upper notch, and a cover is fitted on the upper end of the lower pipe to be fitted into the upper pipe. is there.

[0008]

[Function] The hinge applies a significant load such as a door to the adjusting plate, but the adjusting plate is inserted into the lower notch of the lower tube and firmly held by the lower tube. Even if it is used for a door or the like, there is no possibility that a failure will occur during use.

The hinge holds the right blade with a core rod via a washer inserted into the upper notch of the upper tube.
Since the washer is made of a material with excellent wear resistance and the ball is locked at the tip of the core rod to reduce sliding resistance,
When the door is opened and closed, the right wing rotates lightly and smoothly, and the opening and closing of the door does not become heavy. In addition, there is little wear of the washer and the ball, so the rotation can be performed smoothly for a long time. It is.

Also, when the right wing is moved upward by adjusting the adjusting screw, even if the space between the upper and lower pipes is exposed, the portion is covered with the cover. It is possible to prevent the occurrence of a failure that impedes the opening and closing of a door or the like.
