DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge used for a turning door such as an entrance door or a partition door, and more particularly to a simple hinge capable of adjusting the door vertically and horizontally by a simple mechanism. It is about adjustment hinges.

[0002]

2. Description of the Related Art Conventionally, various types of hinges have been proposed which are capable of performing fine adjustments in the vertical and horizontal directions of a door when a revolving door is mounted. However, there is a problem that the cost is very high due to the complicated mechanism. In addition, in the conventional adjustment hinge, the hinge installation position is specified on either the right side or the left side of the door, so two types, right and left, are required, making production and management complicated and costly. High has become a major factor.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the vertical and horizontal directions of the door can be reliably and easily adjusted by an extremely simple mechanism, and both the right and left sides of the door can be adjusted simply by turning the door upside down. A main object of the present invention is to provide a simple type of adjustable hinge that can be attached to both sides at low cost.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the hinge according to the present invention, an upper cylindrical body 1a formed at one end of the wing plate 1, a lower cylindrical body 2a formed at one end of the wing plate 2, and a large diameter A flange 3a;
A pivot 3 in which an upper shaft portion 3b of an upper portion is slidably inserted into the upper cylinder 1a up and down and a lower shaft portion 3c of a lower portion is inserted in the lower cylinder 2a; and an upper end of the upper cylinder 1a A vertical adjustment screw 4 screwed into the inner peripheral surface and abutting on the upper end surface of the pivot 3, a left and right adjustment screw 5 arranged on the back surface of one of the blades 2, and a wall A such as a fixed frame or a door. A horizontal screw hole 6 that is embedded and receives the left-right adjustment screw 5
a having a. The left and right adjusting screw 5 has a large-diameter flange portion 5a and a driver engagement groove 5b at its head, and is disposed so that the surface of the flange portion 5a is in contact with the back surface of the blade plate 2; 5b is formed so as to be exposed to the outside through an opening 2c provided in the blade plate 2, and furthermore, the respective blade plates 1 and 2 are provided with fixing screw insertion holes 1b and 2b. And The upper and lower positions of the blades 1 and 2 may be reversed.

The decorative tube 7 is preferably slidably covered from the lower outer peripheral surface of the upper cylindrical body 1a to the upper outer peripheral surface of the lower cylindrical body 2a. As a result, the gap between the two cylindrical bodies 1a and 1b can be hidden to enhance the appearance.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the hinge according to the present invention will be described below with reference to an embodiment shown in FIGS. The hinge shown in this embodiment is composed of an upper cylinder 1a formed at one end of a slat 1, a lower cylinder 2a formed at one end of a slat 2, and a large-diameter flange 3a at an intermediate part. The collar 3a
The upper shaft portion 3b of the upper portion is rotatably and vertically slidably inserted into the upper cylindrical body 1a, and the lower shaft portion 3c of the lower portion is
And a pivot 3 firmly fitted to the lower cylinder 2a.
The blade plates 1 and 2 are provided with fixing screw insertion holes 1b and 2b, respectively.

A female screw 1c is formed on the inner peripheral surface of the upper end of the upper cylindrical body 1a, and a vertical adjusting screw 4 is screwed into the female screw 1c. The lower end of the vertical adjustment screw 4 is disposed so as to face the upper end surface of the pivot 3 via the ball 8. The ball 8 can be omitted.

A right and left adjustment screw 5 is arranged on one of the blade plates 1 and 2, for example, on the back surface of the lower blade plate 2, and has a cylindrical receiving hole provided with a horizontal screw hole 6 a for receiving the left and right adjustment screw 5. The tool 6 is embedded in a fitting hole B formed in the wall surface A of the fixed frame (frame). The receiving member 6 is fixed in a state where free rotation is prevented by a rib-like projection 6b provided on the outer peripheral surface.

The left and right adjusting screw 5 has a large diameter flange portion 5a and a driver engagement groove 5b on its head, and is disposed so that the surface of the flange portion 5a is in contact with the back surface of the blade plate 2. The driver engagement groove 5b is formed so as to be exposed to the outside from the opening 2c provided in the blade plate 2,
Thus, the left and right adjustment screw 5 can be rotated by a driver from the outside.

A decorative tube 7 is slidably covered from the lower outer peripheral surface of the upper cylindrical body 1a to the upper outer peripheral surface of the lower cylindrical body 2a. Thereby, the two cylindrical bodies 1a, 1
The appearance is enhanced by hiding the gap between b. Reference numeral 10 denotes a cap removably fitted to the open end of each of the cylindrical bodies 1a, 2a.

The hinge constructed as described above is attached to the wall A of the fixed frame by inserting a wood screw 9 into the screw insertion hole 2b of the blade 2 with the door (not shown) attached to the blade 1. At this time, if it is desired to adjust the distance between the wing plate 2 and the wall surface A of the fixed frame (this is substantially adjustment in the left and right direction of the door), the driver adjusts the left and right adjustment screw 5 with the wood screw 9 loosened. After turning and appropriately screwing or retreating, adjustment can be performed by tightening the wood screw 9 again. The vertical adjustment of the door can be easily performed by removing the cap 10 from the state shown in FIG. 2, rotating the vertical adjustment screw 4, and moving the blade plate 1 up and down.
Also, by inverting the hinge of the present invention, a right-opening door,
It can be used for any of the left doors.

In the holder 6 shown in the above embodiment, the screw hole 6
Although a circular flange 6c is provided at the opening edge of a, the flange 6c can be omitted as shown in FIG. Further, as shown in FIG. 5, the flange 6c may be formed in a rectangular shape so as to reliably prevent free rotation.

Further, in the above embodiment, the lower shaft portion 3c of the pivot 3 is integrally and firmly fitted to the cylinder 2a of the blade plate 2, thereby preventing the blade plate 2 from being released from the pivot 3. However, the blade 2 and the cylindrical body 2a may be relatively rotatable if some kind of separation preventing means is provided.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, it is possible to mount the blade plate 1 on a fixed frame and mount the blade plate 2 on a door for use, or to arrange the blade plates 1 and 2 upside down. In addition, the present invention can be appropriately modified and implemented as long as it has the above-mentioned constituent features, achieves the above-mentioned objects, and has the following effects.

[0015]

Since the adjusting hinge of the present invention is constructed as described above, it has an extremely simple structure and can be manufactured at low cost while having the function of adjusting the horizontal and vertical directions of the door. Has a remarkable effect that it can be mounted on either the left or right side of the door only by inverting the door.
