Since the wedge surfaces 30 and 31 of the lock guide 29 have inclined surfaces which become lower toward the rear (to the right in FIG. 1), when the lock guide 29 is moved rearward by tightening the tightening screw 37. To generate a large force for pushing the pushed portion 22 of the lock member 19,
The friction surface 21 of # 1 strongly presses the inner wall surface of the arm accommodating chamber 9.

A recess 41 for avoiding interference with the fine adjustment bolt 39 described below is provided on the upper portion of the lock guide 29 (see FIG. 1). Fine adjustment bolt 39 with head 39a
However, after being inserted into the through hole 10 of the end wall 6 and the washer 42, the retaining ring 43 is fitted, and the tip of the fine adjustment bolt 39 is screwed into the fine adjustment screw hole 28 of the support arm 11.

Next, the operation of the gate adjustment hinge constructed as described above will be described. First, the lock insertion holes 15 and 16
The lock guide 29 is inserted into the lock guide accommodating recess 12 of the support arm 11 into which the lock member 19 is inserted.
The tightening screw 37 is inserted into the screw insertion hole 26 of the support arm 11 and loosely screwed into the nut 38.

On the other hand, a fine adjustment bolt 39 with a bolt plate 4 is screwed into the fine adjustment screw hole 28. For attachment, the bolt plate 4 is fitted in the plate fitting groove 3 of the case 1. The tip portion 11a of the support arm 11 is inserted into the arm accommodating chamber 9, and the auxiliary plate 5 is fitted into the plate fitting groove (see FIG. 9A). Then, after adjusting the height of the hinge pin 25 of the support arm 11 according to the gate D, the bolt 40 inserted into the mounting bolt hole 2 of the mounting seat 1a with the opening 7 of the arm accommodating chamber 9 of the case 1 facing the gate D. The case 1 is fixed to the gate post G (see FIG. 11). At this time, the end wall 6 is sandwiched between the inner wall surface of the arm storage chamber 9 and the gate post G.

At this time, since the tightening screw 37 has not been tightened yet, the guide plate 35 has the lateral hole 32.
It is slidable inside, and the support arm 11 can be freely tilted within a horizontal plane in a state where both ends of the guide plate 35 are in contact with the inner wall surface of the arm accommodating chamber 9.
(B)). The depth at which the support arm 11 is inserted into the case 1 depends on the screwing position of the fine adjustment bolt 39.
It can be made shallow as in (B) or deep as in FIG. 9 (C).

When the tightening screw 37 is firmly tightened into the nut 38, the lock guide 29 is slightly moved to the gate D side,
The wedge surfaces 30 and 31 press the lock member 19 against the inner surface of the arm housing chamber 9, and the support arm 11 is fixed to the case 1.
Since the tightening force of the tightening screw 25 is increased by the wedge effect of the wedge surfaces 23 and 24, the support arm 6 is firmly fixed to the case.

Further, since the guide plate 35 is tightened, it cannot slide in the lateral hole 32 and the displacement of the support arm 11 is prevented, so that the support arm 11 is subjected to repeated impact force by opening and closing the gate G. The position of does not shift. The insertion depth of the support arm 11 into the case 1 is
The fine adjustment bolt 39 allows fine adjustment.

When changing the hand of the gate adjustment hinge, it is sufficient to rotate the bolt plate 4 by 180 degrees and insert it into the plate fitting groove 3. When the distance between the gate post G and the through hole 10 at the center of the bolt plate 4 is the same as the distance between the through hole 10 and the inner wall surface of the arm accommodating chamber 9, the through hole is obtained even if the hand of the adjustment hinge for the gate post is changed. Since the position does not change to 10, the auxiliary plate 5 is unnecessary (FIG. 10 shows an example of a gate adjustment hinge without the auxiliary plate 5). By exchanging the bolt plate 4 and the auxiliary plate 5, one type of case 1 can handle two types of distances.

[0030]

Since the present invention is constructed as described above, it has the following effects. (1) Since the tightening screws are tightened from the gate side, the work space can be widened and the screw tightening work becomes easier. (2) Since the tightening screw is installed below the support arm, the head of the screw is not exposed in a conspicuous place. Therefore, the appearance of the gate adjustment hinge is improved as compared with the conventional one.

(3) Since the tightening force of the tightening screw is increased by the wedge surface, it does not loosen even when subjected to repeated impact loads due to opening and closing of the gate. Moreover, since the guide plate prevents the support arm from tilting, the position of the hinge pin can be accurately maintained. (4) The gate adjustment hinge of the present invention is convenient because it can be used as a double-handed gate with a simple operation.
