4 and 5 show an outline of a conventional gate.
In the figure, reference numeral 1 denotes a pair of left and right gate posts, and a pair of left and right gate doors 2 are rotatably attached to the insides of the gate posts 1 by a pair of upper and lower hinges 3, respectively.

Each of the above hinges 3 is fixed to the gate pole 1, a case 4, a gate pole side member 6 rotatably attached to the case 4 about a shaft 5, and a rotatably attached to the end of the member 6 about a shaft 7. It is composed of a gate side member 8 and the gate 2 is fixed to the member 8.

In this conventional technique, the vertical and lateral adjustment of the left and right gates 2 can be relatively easily performed by adjusting the long holes and the mounting bolts in the mounting portion of the case 4 to the gate post 1. The adjustment in the front-rear direction, that is, the inward / outward direction of the gate is performed by rotating the member 6 around the shaft 5 to adjust the position of the shaft 7 in the front-rear direction, and after adjustment, it is fixed by the fixing bolt 9.

[Problems to be solved by the device]

In the case of the conventional gate hinge 3 described above, the entrance / exit of the gate 2 is adjusted by rotating the gate post side member 6 about the shaft 5, so that the shaft 7 serving as the rotation center of the gate 2 is centered on the shaft 5. Move along an arcuate trajectory.

For this reason, although the position of the gate 2 in the front-back direction can be adjusted, the gate 2 will move slightly to the left and right along with it, and the left and right positions of the gate 2 that were previously adjusted will be incorrect. There is the problem of having to do it again.

An object of the present invention is to solve the above problems and to provide an adjusting device in which the left and right positions do not change even when the front and rear positions of the gate are adjusted.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a long hole in the front-rear direction at the upper and lower ends of a case fixed to a gate pole, and a vertical fixing bolt inserted in the middle part of the gate pole side member is used for the upper and lower holes. It can be fixed at any position in the long hole, and a longitudinal adjustment bolt is rotatably and axially immovably attached to the other end of the case. It is screwed into the screw hole in the front-back direction.

[Action]

Since the present invention has the above-mentioned configuration, when adjusting the front and rear position of the gate, the fixing bolt mounted in the long hole of the case is loosened so that the bolt can freely move along the long hole along with the gate post side member. State.

Then, when the adjusting bolt is turned, the gate post member having the screw hole screwed into it moves straight forward and backward along the adjusting bolt, so that the rotation of the adjusting bolt is stopped when the position of the gate is appropriate.

After that, the fixing bolt is tightened to fix the gate pole side member to the case, and the adjustment work is finished.

〔Example〕

In the embodiment shown in FIGS. 1 to 3, 11 is a gate pillar, 12 is a gate, and 13 is a hinge.

The hinge 13 is formed by rotatably connecting the gate pillar side member 16 and the gate side member 18 attached to the case 14 by a shaft 17. The lower end of the shaft 17 is vertically fixed to one end of the member 16 and fixed to the gate 12. The shaft hole of the gate side member 18 and the shaft 17 are rotatably fitted through the washer 15.

One end of the case 14 is an opening, elongated holes 20 in the front-rear direction are formed on the upper and lower sides of the case 14 on this side, and an inner case 21 is mounted in the other end of the case 14. Reference numeral 22 is an adjusting bolt. A peripheral groove 23 is formed inside the head of the bolt 22 as shown in FIG. 2, and the bolt 22 is fitted into a dullama hole 24 on the front surface of the case.

The darma hole 24 has a large-diameter portion with a diameter into which the male screw of the bolt 22 is fitted, and a small-diameter portion is fitted with only the circumferential groove 23 to prevent the bolt 22 from moving back and forth. Support holes 25 and 26 that fit into the bolt 22 are provided at the front and rear at the position where the groove 23 enters the small diameter portion of the dullama hole 24, but the rear hole 26 is cylindrical and holds the rear end of the bolt 22.

A screw hole 28 into which the adjusting bolt 22 is screwed is provided at the other end of the gate post member 16, and a vertical hole 29 for inserting the fixing bolt 27 is provided at an intermediate portion of the member 16.

Seat plates 30 are integrally provided on the upper and lower rear sides of the case 14,
The seat plate 30 is provided with a long hole 31 for inserting the mounting bolt 32.

The adjusting bolt 22 is inserted into the large diameter portion of the dharma hole 24 of the case 14, its head is brought into contact with the front surface of the case 14, and then is laterally displaced, and its circumferential groove 23 is engaged with the small diameter portion of the dharma hole 24. To combine.

Then, the inner case 21 is fitted from the rear of the case 14, and at this time, the other end of the gate pillar side member 16 is inserted into the inner case 21.
The bolt 22 is inserted into the support hole 25 in the front of the inner case 21 and then screwed into the screw hole 28 of the member 16 so that the rear end of the bolt 22 protruding rearward of the member 16 is inserted into the support hole 26. Fit loosely.

Further, the fixing bolt 27 is inserted into the vertical hole 29 of the member 16 in the case 14 through the elongated hole 20 above the case 14, and the nut 33 is screwed into the lower end of the bolt 27 protruding from the elongated hole 20 in the lower part of the case 14. .

As described above, the case 14 to which the gate post member 16 and the inner case 21 are attached is fixed by screwing the plurality of fixing bolts 32 inserted into the upper and lower long holes 31 into the screw holes of the gate post 11.

When fixing the case 14 to the gate post 11, the shaft 17 is directed upward, and the gate-side member 18 fixed to the gate 12 is lowered from above the shaft 17 so that the shaft 17 is fitted into the shaft hole of the member 18. The gate 12 is attached by this.

After mounting the gate 12 as described above, in order to adjust the front-back position of the gate 12, the fixing bolt 27 is loosened to remove the member 16
When the adjustment bolt 22 is normally or reversely rotated, the bolt 22 does not move forward and backward, and the member 16 having the screw hole 28 screwed therein moves forward and backward. The front and rear positions of the gate 12 can be finely adjusted.

In the above case, since the bolt 27 of the member 16 moves back and forth within the elongated hole 20, the shaft 17 at the end of the member 16 does not move in an arc, and there is no possibility that the left and right positions of the gate 12 will be misaligned.

Thus, when the adjustment is completed, the fixing bolt 27 is tightened to fix the member 16 to the case 14.

It is needless to say that an opposite-handed hinge is used for the gate on the opposite side of the drawing, but it is not necessary to make parts of the opposite-handed one, and the parts may be made to be opposite-handed when assembled. The vertical and horizontal adjustment of the gate is performed by a known method.

[Effect of device]

As described above, according to the present invention, the longitudinal holes are provided at the upper and lower ends of the case in the front-rear direction, and the vertical fixing bolts inserted in the middle portion of the gate post member are inserted into the upper and lower oblong holes. It can be fixed at any position, and a longitudinal adjustment bolt is attached to the other end of the case in a freely rotatable and axially immovable manner, and the adjustment bolt is screwed into the longitudinal screw hole of the gate post member. Therefore, when adjusting the front and rear position of the gate, loosen the fixing bolt attached to the long hole of the case and make the bolt move freely along the long hole together with the gate post side member, When the adjusting bolt is turned, the gate post member having the screw hole screwed into it moves straight forward and backward along the adjusting bolt, so that the gate moves only forward and backward. Therefore, since the gate does not move left and right when the gate is adjusted in the front-rear direction, the gate can be adjusted easily and accurately. Further, after the adjustment, the gate post member can be fixed only by tightening the fixing bolt inserted in the long hole of the case, so that there is an effect that there is no fear that the installation of the gate will be misaligned after the adjustment.
