Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fittings such as doors and windows that are opened and closed by a pivot hinge, and more particularly to a fitting in which the structure of the pivot hinge for supporting the weight of a door is improved.

[0002]

2. Description of the Related Art Generally, in a fitting such as a door in which a door body is attached to a mounting frame of the door body via a pivot hinge, pivot hinges are arranged at an upper portion and a lower portion of the door body. The pivot hinge on the side supporting the weight of the door body (usually, the lower pivot hinge) has a hinge body that is provided in the door body and its mounting frame, respectively, and vertically opposed to each other, and the pivot body is attached to the lower hinge body. An upright hinge body is provided with a hole into which the pivot is rotatably fitted. The height of the door can be adjusted by attaching a washer for height adjustment to the pivot. However, in the above fitting, there is a problem in that the door body must be temporarily removed in order to mount the washer on the pivot when the height of the door body is adjusted, and the work is difficult.

On the other hand, in order to solve such a problem,
For example, as disclosed in Japanese Utility Model Application Laid-Open No. 50-143336, a screw hole is formed in the hinge body on the door side, and the side surface of the screw hole is chamfered for engaging a rotary tool and one end thereof is provided. It has been proposed that a bolt having a round shaft portion (pivot) is screwed into it, a lock nut is screwed into this bolt, and the round shaft portion is loosely fitted into a shaft pot formed in the frame side hinge body. There is. According to this fitting, the height can be adjusted by rotating the bolt without removing the door body.

[0004]

However, in the above fitting, the chamfer on the side surface of the bolt may be hidden by the lock nut and not exposed to the outside. In this case, the lock nut is first rotated to lock it. A gap where the chamfer of the bolt is exposed is created between the nut and the hinge body on the door side, and the height is adjusted by engaging the rotating tool with the chamfer of the bolt and rotating the bolt from the gap. After the adjustment, it is necessary to perform the operation of tightening the lock nut on the door side hinge main body side, and it is difficult to engage the rotating tool with the chamfer of the bolt from a narrow gap,
Not only is the thread of the bolt easily damaged, but there is also the problem that complicated operation is required for height adjustment. Further, since the round shaft portion having a diameter smaller than that of the bolt is loosely fitted in the shaft pot to support the weight of the door body, the strength is not suitable for a relatively large and heavy door body.

Therefore, the present invention has been made to solve the above problems, and the height of the door body can be easily adjusted by a simple operation without removing the door body, and is relatively large and heavy. It is an object of the present invention to provide a fitting that can be easily applied to a door body with a door.

[0006]

In order to achieve the above object, the invention according to claim 1 is a fitting having a pivot hinge for mounting the door body on its mounting frame so that the door body can be opened and closed. The pivot hinge on the supporting side has a hinge body that is provided on each of the door body and the mounting frame and vertically opposed to each other, and a male screw portion formed at one end of the pivot is raised in a screw hole provided on one of the hinge bodies. A flange portion having a diameter larger than that of the male screw portion is provided in the pivot so as to receive the other hinge body in the pivot, and an engaging portion for engaging a rotary tool is formed at an end portion of the collar portion or the pivot. At the same time, a lock nut is screwed into the male threaded portion, and the pivot is rotatably fitted in a hole provided in the other hinge body.

According to a second aspect of the present invention, there is provided a fitting having a pivot hinge for mounting the door body on its mounting frame so as to be openable and closable, wherein the pivot hinge for supporting the weight of the door body is:
Each of the door body and the mounting frame has a hinge body that vertically opposes, and a male screw portion formed at one end of the pivot is screwed into a screw hole provided in one of the hinge bodies so that height adjustment is possible. In order to receive the other hinge main body in the pivot, a flange portion having a diameter larger than that of the male screw portion is provided, and an engaging portion for engaging a rotary tool is formed at an end portion of the collar portion or the pivot.
A spacer for height adjustment is provided between the flange portion and one of the hinge bodies so that the spacer can be inserted and removed in the radial direction of the male screw portion, and the pivot is rotatably fitted in a hole provided in the other hinge body. It is characterized by

[0008]

According to the invention of claim 1, when the height of the door is adjusted, the lock nut is loosened, and the rotary tool is engaged with the engaging portion formed on the flange portion of the pivot or the end portion of the pivot. Then, the height is adjusted by rotating the pivot, and the lock nut may be tightened after the height is adjusted. Since the engaging part for the rotary tool is formed on the collar part of the pivot or the shaft part of the pivot, unlike the conventional one formed on the male screw part, there is a risk of requiring complicated operation and damaging the male screw part. Therefore, the height of the door can be easily adjusted by a simple operation without removing the door. Moreover, since the pivot is designed to receive the weight of the door body by the flange portion which is larger in diameter than the male screw portion and has a large receiving area, a high supporting strength is obtained, and the door body is relatively large and heavy. Can also be easily applied.

According to the second aspect of the present invention, when the height of the door is adjusted, the rotary tool is engaged with the engaging portion formed on the flange portion of the pivot or the end portion of the pivot to rotate the pivot. The height can be adjusted by doing so, and after adjusting the height, a spacer matching the gap can be inserted between the flange portion and the hinge main body in the radial direction of the male screw portion, and this can be tightened with the collar portion. While the invention according to claim 1 performs the height adjustment steplessly, the invention according to claim 2 performs the height adjustment stepwise, but like the invention according to claim 1, The height can be easily adjusted by a simple operation without removing the door body, and can be easily applied to a relatively large and heavy door body.
