DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge mounting method used when a door is mounted on a fixed member such as a pillar.

[0002]

2. Description of the Related Art When a door is attached to a fixed member such as a pillar, a hinge is often used. FIG. 3 (a), (b)
Shows an example of a hinge 51 supporting a heavy door. The hinges 51 are provided with shaft holes 54 and 55 on one side of a mounting plate 52 for the fixed side member and a mounting plate 53 for the door side, respectively.
And a shaft pin 56 fitted in the shaft holes 54 and 55.
Each of the mounting plates 52 and 53 rotates about the center. One side of the mounting plate 53 on the door side is engaged between one side of the mounting plate 52 on the fixed side member, and a thrust ball bearing 59 is sandwiched in this engaging portion. I have. Thrust bearings are used in particular in hinges that support heavy doors.

At the upper and lower ends of a shaft hole 54 of a mounting plate 52,
A boss 58 provided on the lower surface side of the cap 57 is fitted,
The shaft pin 56 is retained. Pins 60 are driven into the boss 58 of the cap 57 through one side of the mounting plate 52, and the mounting plates 52 and 53, the shaft pin 56, and the cap 57 are integrally assembled so as not to be disassembled.

FIG. 4 shows a state in which a plurality of hinges 51 are attached to the pillar 13 by welding. Usually, at the time of welding the hinges 51, the mounting position is marked on the pillar 13 in advance, but the center axis 66 of the shaft pin 56 of each hinge 51 may be slightly shifted. Misalignment of the center axis 66 of each shaft pin 56 not only prevents smooth opening and closing of the door, but also generates an excessive load on the sliding portion on one side of the mounting plates 52 and 53 when the door is opened and closed. There is a problem that the ball bearing 59 is damaged and the life of the hinge 51 is significantly reduced.

[0005] The hinge may be attached to a pillar or the like with a bolt. In this case, a method of adjusting the mounting position of the hinge with the elongated hole is often adopted. Also in this case, it is difficult to accurately match the center axes of the plurality of hinge shaft pins, and the same problem as in the case of the above-described attachment by welding occurs.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to accurately match the center axes of the shaft pins of each hinge when mounting a door with a plurality of hinges. is there.

[0007]

Means for Solving the Problems To solve the above problems,
Therefore, the present invention relates to a method for mounting a plurality of hinges, in which two mounting plates are pivotally attached to a shaft pin with shaft holes provided on one side thereof, in a straight line on a fixed member. ,
The shaft pin of each hinge can be removed from the shaft hole,
A straight centering rod having substantially the same diameter as the shaft pin is inserted into a shaft hole from which the shaft pin of each hinge is removed, and a plurality of hinges through which the centering rod is inserted are temporarily fixed to the fixed side member. Then, the mounting position of each hinge is determined, and thereafter, the centering rod is pulled out, each shaft pin is fitted into the shaft hole of each mounting plate, and each hinge is mounted at the positioned mounting position. I did it.

That is, the shaft pin of each hinge can be removed.
And insert the centering rod into the shaft hole from which the shaft pin of each hinge was removed.
Positioning of the mounting position through
The center axis of the numbered shaft pin can be precisely matched
You.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1A and 1B show this implementation.
1 shows a hinge 1 used in the form. The hinge 1 is provided with shaft holes 4 and 5 on one side of a mounting plate 2 for the fixed member and a mounting plate 3 for the door, respectively, and has a shaft pin 6 fitted in the shaft holes 4 and 5. Each of the mounting plates 2 and 3 rotates around the center. One side of the mounting plate 3 on the door side is engaged between one side of the mounting plate 2 on the fixed side member, and a thrust ball bearing 9 is sandwiched in this engaging portion. I have. Instead of the thrust ball bearing 9, a slide bearing made of an oil-impregnated alloy or the like may be used.

Bosses 8 provided on the lower surface side of the cap 7 are fitted into upper and lower ends of the shaft hole 4 of the mounting plate 2, respectively.
Has been retained. A set screw 10 with a hexagonal hole is screwed into the upper and lower ends of one side of the mounting plate 2. The tip of the set screw 10 is inserted into an annular groove 11 provided in a boss 8 of the cap 7, and the cap 7 is It is fixed to one side of the mounting plate 2. Therefore, by retracting the tip of the set screw 10 from the annular groove 11, the cap 7 can be removed and the shaft pin 6 can be easily removed.

Next, a method of attaching a plurality of hinges 1 to a pillar as a fixed member will be described. First, the shaft pin 6 is removed as described above, and a straight centering rod 12 having substantially the same diameter as the shaft pin 6 is passed through the shaft holes 4 and 5 of each hinge 1 as shown in FIG. Then, each hinge 1 is temporarily fixed to a mounting position of the pillar 13 by a clamp tool (not shown). In this state, holes 14 and 15 for knock pins for positioning are made in the mounting plate 2 and the pillar 13.

Next, the clamp tool is removed and the centering rod 12 is removed, and the shaft pins 6 are fitted into the shaft holes 4 and 5 from which the centering rod 12 is removed, and the cap 7 is attached. After this, the holes 14 and the pillars 13 of the mounting plate 2 of each hinge 1
With the hole 15 of
Each hinge 1 is welded to the pillar 13 as shown in FIG. Since the center axis 16 of the shaft pin 6 of each hinge 1 is precisely matched, the door attached to the attachment plate 3 (not shown)
Can be opened and closed smoothly.

When a hinge is attached to a fixed member such as a door frame at a factory, there is sufficient space above and below the fixed member, so that each hinge is inserted with a centering rod passed through each hinge. The work can be performed by attaching to the fixed side member, then removing the centering rod, inserting the shaft pin and attaching the cap. In this case, the work of temporarily fixing the hinge to the fixed side member and positioning the mounting position can be omitted.

As a method for allowing the shaft pin to be pulled out, as described in this embodiment , the cap is set with the set screw.
In addition to the locking method, for example, a method in which the boss of the cap is threaded, and the cap is screw-coupled to a shaft hole on one side of the mounting plate to be detachably and fixably mounted may be employed.

[0015]

As described above, the hinge mounting method according to the present invention enables a plurality of hinge shaft pins to be pulled out.
After positioning the mounting position with the centering rod passed through the shaft hole from which the hinge shaft pin was removed, each hinge was mounted, so that the center axis of each hinge shaft pin matched precisely. The door can be opened and closed smoothly, and the life of the hinge can be improved.
