In the above-mentioned conventional hinge, since the vertical gap and the vertical and horizontal gaps between the door opening and the door can be adjusted, the front of the door with respect to the door opening is in a proper position. Although they can be mounted, any of these conventional examples has the following problems to be improved because the door cannot be adjusted in the thickness direction.

As shown in FIG. 8, a mounting recess 4 for mounting the hinge plate 6 is dug in the entrance opening 3. The position of the door 2 in the thickness direction (direction of arrow A) is determined by the position of the recessed hole 4 dug in the entrance opening 3. Therefore, for example, with respect to the width W of the hinge plate 6,
When the width of the recessed hole 4 is dug wide by L, a step is formed between the surface 301 of the entrance / exit opening 3 and the surface 201 of the door 2 by a dimension L, which makes the appearance unpleasant. In order to hide the space between the door 2 and the door 2, for example, when the member 5 is attached to the entrance opening 3 in advance, the edge of the door 2 may come into contact with the member 5 and the door 2 may not close. is there.

When such a situation occurs, the door 2 must be reattached. Therefore, the hinge plate 6 must be attached to the entrance / exit opening 3 in a state where the hinge plate 6 is pulled out from the concave hole 4 by the dimension L, so that a concave hole of the dimension L appears on the surface of the entrance / exit opening 3 to impair the appearance and to make the hinge plate Since the hinge plate 6 is attached to the entrance / exit opening 3 by passing a screw through the hole 13 (FIG. 9) provided in the part 6, when the dimension L is small, the hinge plate 6 is newly added in a state of being close to or interfering with the screw hole formed in the entrance / exit opening 3. There is a problem in that the screw hole cannot be opened and the mounting of the door 2 in the width direction cannot be substantially corrected.

The present invention has been made in view of the above problems, and it is possible to adjust the vertical gap and the vertical and horizontal gaps between the door opening and the door, and also to adjust the thickness of the door. It provides a hinge that is made possible.

There is. The position of the tongue piece 9 in the thickness direction with respect to the concave portion 8 can be adjusted by the screwing degree of the bolt 20 and the adjusting screw 22.

Reference numeral 901 denotes a mounting portion for rotatably mounting on the hinge plate 6 side, the shape of which is specified according to the type of the hinge plate 6, and the tongue piece 9 is moved up and down with respect to the hinge plate 6, The upper and lower gaps T1 and B1 between the door opening 3 and the door 2 shown in FIG. 12 can be adjusted.

For example, in the case of applying to the hinge plate 6 of FIG. 9 shown as a typical example using the tongue piece 9 as shown in FIG. 5, a female screw is provided on the inner surface of the mounting portion 901 and the hinge 1 The screw portions 27 and 28 of the bolts 17 and 18 serving as hinge shafts are screwed into the female screw 29 provided on the inner surface of the mounting portion 901, and the bolts 17 and 18 are
The unscrewed shaft portion is inserted so as to straddle the winding portions 10 and 11 having substantially the same inner diameter and the C ring 12, and the tongue piece 9 is restrained in the rotational direction with respect to the C ring 12. In this way, the weight of the door 2 is received by the shaft portions of the bolts 17 and 18, so that the screw portions 27 and 28 are not loaded. In this way, the load of the door 2 is received by the shaft portions of the bolts 17 and 18 and the load is not received by the screw portions 27 and 28, so that the bolt 2 is attached to the door opening 3 when the door 2 is attached. And the rotation of the door 18 is facilitated, and a vertical gap T between the door opening 3 and the door 2 is provided.
Adjust 1 and B1.

The operation of the present embodiment thus constructed will be described below. The hinge plate 6 is attached to the door opening 3 side, and the hinge plate 7 is attached to the door 2 side. First, Fig. 12
The adjustment of the upper and lower clearances T1 and B1 of the door 2 in FIG. 5 will be described. In FIG. 5 (the hinge plate 6 is an example and not limited to this), the screw portions 27 and 28 of the bolts 17 and 18 are screwed into the female screw 29. By attaching the tongue piece 9 to the hinge plate 6 rotatably, and adjusting the screwing amount of the bolts 17 and 18,
The tongue piece 9 can be positioned and held at an arbitrary position between the winding portions 10 and 11, and the door 2 can be moved in the vertical direction to adjust the gaps T1 and B1.

For example, if the screws 17 and 18 are screwed in equal amounts, the tongue 9 can be positioned and held by the bolts 17 and 18 in the center of the winding portions 10 and 11, and the screwing of the bolt 17 can be loosened. While tightening the bolt 18, the tongue piece 9 moves upward by the amount of loosening and is held in position by the bolts 17 and 18, and conversely, by tightening the bolt 17 while loosening the screw engagement of the bolt 18, The tongue 9 moves downward and is held in position by the bolts 17 and 18. In this way, the door 2 moves up and down by adjusting the screwing amount of the bolts 17 and 18.

Next, the upper left and right L1 of the door 2 in FIG.
And R1 and the lower left and right L2 and R2 clearances will be described. The width dimension of the recess 8 is larger than the thickness of the tongue 9 so that the tongue 9 can move in the recess 8 in the thickness direction. As a result, the position of the tongue piece 9 in the recess 8 is arbitrarily determined, so that the door 2 after attachment is moved in the left-right direction, and the door opening 3 and the door 2 are attached.
It is possible to adjust the gap between the edges of the.

The specific adjustment of this gap is performed as follows. In Fig. 12, adjust the upper hinge 1 side to make the gap R
When 1 is narrowed, the lower clearance R2 is widened (L1 is widened and L2 is narrowed), and the door 2 is inclined with respect to the entrance / exit opening 3. Therefore, the clearance is adjusted so that L1 = L2 and R1 = R2. In FIG. 11, while loosening the adjustment screw 22, the bolt 20
When the tongue piece 9 is tightened, the tongue piece 9 can move to the right side of the drawing to move the door 2 in the direction of arrow (a) in FIG. 12, and conversely, by tightening the adjusting screw 22 while loosening the bolt 20, The door 2 can be moved in the direction of the arrow (b) of 12. Thereby, for example, by adjusting the lower hinge 1'with reference to the upper hinge 1, the gap L1 = L
2 and R1 = R2.

Next, the adjustment of the door 2 in the thickness direction will be described. In FIG. 1, the valley portion of the screw portion 322 of the adjusting screw 32 is engaged with the projection portion 33 of the tongue piece 9, and the through hole 240 of the bolt 20 and the step portion of the adjusting screw 22 opened in the tongue piece 9. Since the hole 250 into which is fitted is a long hole, by rotating the adjusting screw 32 shown in FIG. 1 from the side of the hinge plate 7,
The door 2 can be moved in the arrow (C) direction shown in FIG. The hinge plate 7 is then recessed 8 as shown in FIG.
The part where is formed is the protrusion 30 symmetrically,
Since the protruding portion 30 is exposed on the side surface of the door 2, the adjusting screw 32 can be rotated from the side surface of the door 2 using a jig as shown in FIG.

Next, when the holes formed in the tongue 9 are arcuate long holes 241 and 251 as shown in FIG. 3 or elliptical holes 242 and 252 as shown in FIG. When the tongue piece 9 is moved in the inserting direction of the recessed hole 8 by rotating 32, the bolt 20 and the adjusting screw 22 are guided to the above holes, so that the door 2 moves up and down by the shift amount ΔL of the center of the bolt 20. However, the upper and lower clearances T1 and B1 of the door 2 previously adjusted by the bolts 17 and 18 can be finely adjusted.

Further, the arc-shaped elongated holes 241 and 251 have the following effects. In FIG. 12, for example, when the hinge 1 side is fixed (position in the upper thickness direction of the door 2) and positioned in the lower thickness direction of the door 2, the through hole of the tongue piece 9 of the lower hinge 1'is obtained. In 241 and 251, a circular arc whose radius is the distance W between the hinges 1 and 1'is drawn. Therefore, since the through-holes 241 and 251 are arc-shaped long holes, after the upper or lower side of the door 2 is positioned in the thickness direction, the other side is positioned in the thickness direction. It is possible to facilitate the positioning work. However, as shown in FIG. 3, since the arcuate elongated holes 241 and 251 have a downward curvature, the tongue piece 9 has the hinge 1 side fixed and the 1 ′ side moved to move the door 2 thickness. It will have to be aligned in the direction. Of course, if the curvatures of the arcuate elongated holes 241 and 251 of the tongue piece 9 are reversed, the opposite is true.

On the other hand, the long holes 242 and 2 shown in FIG.
If the shape is elliptical like 52, the arc-shaped long hole 2
There is no orientation like 41 and 251 and it is possible to position the upper or lower side of the door 2 in the thickness direction and then position the other side in the thickness direction, and Since the tongue piece 9 has no directionality, the hinge plates 6 and 7 can be attached in any direction to the pillar or door, and workability is good.

[0032]

As described in detail above, according to the present invention, the through-hole of the tongue piece is a long hole that can adjust the left and right and the vertical and horizontal gaps between the door opening and the door by using the tongue piece. The adjustment screw provided on the side surface of one of the hinge plates is screwed into the protrusion provided on the tip of the tongue to move the tongue up and down, left and right, and in the thickness direction of the door. By turning the adjusting screw provided on the side of the hinge plate with a tool while it is attached to the door, even if there are some errors in the holes dug in the pillar or the wall, the door can be accurately positioned with respect to the entrance opening. Can be installed.

Then, the through hole formed in the tongue is formed into an arc-shaped long hole, and the tongue is fixed to the hinge plate by aligning the position of the upper door in the thickness direction of the door, and the tongue in the thickness direction of the lower part of the door is adjusted. Since the positions can be aligned, the vertical clearance of the door can be finely adjusted and the workability of mounting the door can be improved.

Further, the through hole formed in the tongue is made elliptical,
Either the upper or lower part of the door can be aligned in the thickness direction of the door, and the tongue can be fixed to the hinge plate, then the door on the other side can be aligned in the thickness direction. Even if it is reversed, since the door can be aligned in the thickness direction as described above, the vertical clearance of the door can be finely adjusted and the work of mounting the door can be further improved.
