On the other hand, an opening frame b serving as a closet frame is attached to four sides of an opening on the front surface of the storage unit serving as a closet, and a pivot shaft 2a,
Rails 3a and 3b for guiding 2b are embedded. The rails 3a and 3b are configured in accordance with the shapes of the ends of the pivot shafts 2a and 2b. In the embodiment, the rails 3a and 3b have a flange f on the inner surface.

The pivot shafts 2a, 2b are provided at the ends of the upper and lower rails 3a, 3b attached to the opening frame b serving as a closet frame.
Bearings 4a and 4b into which the front ends b are fitted are provided. The bearings 4a and 4b are upper bearings 4a installed on the upper rail 3a.
And a lower bearing 4b installed on the lower rail 3b.
The lower bearing 4b installed on the lower rail 3b includes a shaft hole 4h into which the lower pivot shaft 2b is fitted, a plate nut for fixing the lower bearing 4b on the lower rail 3b, and a fixing bolt v.

The fixing bolt v is inserted into a fixing bolt hole 4v formed in the lower rail end of the lower bearing 4b main body, fits with a plate nut p on the lower surface side of the lower bearing 4b, and tightens the bolt v to fix the plate. Nut p is lower bearing 4b
, And the lower bearing 4b and the flange 3f of the lower rail 3b are sandwiched between the lower bearing 4b and the lower rail 3b.
b. Reference numeral 4r denotes a rail receiver serving as a guide for the collar 3f.

The shaft hole may be of a type in which the nut and the shaft are fitted and the depth of the shaft hole can be adjusted by rotating the nut. Fine adjustment of the vertical position of d can be performed.

On the other hand, the upper bearing 4a installed on the upper rail 3a is provided with a slope which is thinner at the center of the upper rail and is thicker toward the end of the upper rail, and which pushes down the pivot shaft toward the door when the door is fixed. Near the upper end (upper rail end side), a shaft hole into which the pivot shaft fits, a plate nut for fixing the upper bearing to the upper rail, and a fixing bolt are provided. Further, the shaft hole may be in the middle of the slope.

The shaft hole 4h is desirably provided with a flat portion connected to the upper end of the slope 4s as shown in FIG.
Even if the upper pivot shaft 2a comes off from h, the upper pivot shaft 2a does not slide on the slope 4s and the upper pivot shaft 2a does not come off from the upper rail 3a. Fixing bolt v is lower bearing 4b
Similarly, the upper bearing 4a is inserted into a fixing bolt hole 4v drilled on the end side of the upper rail 3a of the main body, fits with the plate nut p on the back side of the upper bearing 4a, and tightens the bolt v to raise the plate nut p. The bearing 4a is fixed on the upper rail 3a while sandwiching the flange 3f of the upper rail 3a.

As described above, the fixing bolt v is provided at the end of the upper bearing 4a at the end of the upper rail 3a, and the slope 4 is provided at the center of the upper rail 3a.
The lower rail 3b has a lower bearing 4b fixed to the lower rail 3b end side with a fixing bolt v and a lower rail 3b.
b It is fixed so that the shaft hole 4h is located at the center side.

FIG. 2 shows a case where the shaft hole 4h is provided on the slope 4s. And guide 4g is slope 4.
s, and the tip of the upper pivot shaft 2a is guided by the guide 4g.

As described above, the slope 4s is attached to the upper bearing 4a.
And the upper pivot shaft 2a that has traveled on the upper rail 3a
When the tip reaches the slope 4s and is pushed down to the door d side, and the shaft hole 4h is provided at the end side of the upper rail 3a of the slope 4s, the lower pivot 4b is attached to the lower bearing 4b when attaching the door d to the opening frame b. The upper pivot shaft 2a can be fitted into the upper bearing 4a only by raising the pivot 1a at the end side of the upper rail 3a while applying the upper pivot shaft 2a to the upper rail 3a with the shaft 2b applied thereto. Even if there is, the door d can be easily attached.

Further, as shown in FIG. 8, the upper pivot shaft 2a fitted in the shaft hole 4h does not come off the upper bearing 4a.
A stopper st can be provided. This stopper st pushes down the upper pivot shaft 2a played by the upper bearing 4a when fixing the upper pivot shaft 2a performed by the upper bearing 4a to the door d when fixing the door d, or moves the upper pivot shaft into the shaft hole 4h. The upper pivot shaft 2a is prevented from slipping out of the shaft hole 4h and traveling in the direction of the slope 4s without hindering the action of fitting the 2a, thereby preventing the pivot 1 from coming off the opening frame b.

The stopper st is composed of a leaf spring having elasticity, is located on the slope 4s (rail center side) from the shaft hole 4h, the base end t is fixed on the upper bearing 4a, and the free end is the shaft hole 4h. Extended to the end of the shaft hole 4h
The bent portion u of the leaf spring is inserted into the shaft hole 4h. In a normal state, the free end of the stopper st is separated so that the upper pivot shaft 2a does not come off the shaft hole 4h. By doing so, when the pivot shaft is fitted, the shaft hole narrows, and the pivot shaft can be tightened and held.

The upper pivot shaft 2a is mounted on the upper bearing 4a.
When fitting over, when passing over the stopper st,
The stopper st is deformed by being pressed against the upper bearing 4a by the resiliently biased upper pivot shaft 2a so as not to obstruct the passage of the upper pivot shaft 2a from the slope 4s toward the shaft hole 4h. .

[0025]

Further, as shown in FIG.
The bent portion u of the leaf spring is inserted into the shaft hole 4h. In this way, the bent portion u comes into contact with the upper pivot shaft 2a as a surface, and has an advantage that the panel panel is less likely to be worn as compared with the case where the plate is not bent.

By providing such a stopper st, the upper pivot shaft 2a fitted into the upper bearing 4a becomes difficult to come off, and the upper pivot shaft 2a can be moved while the door d is being used by the shaft hole 4h of the upper bearing 4a. It is possible to prevent accidents such as falling out of the vehicle.

Next, a method of fixing the pivot 1 in the present fixing structure will be described with reference to FIGS. The rails 3a and 3b and the bearings 4a and 4b are installed in advance on the upper and lower sides of the earpiece frame b of the storage portion serving as a closet.

First, as shown by the dotted line in FIG. 6, the upper bearing 4a and the lower bearing 4b are fixed to the ends of the rails 3a and 3b, respectively.
The tip of the lower pivot shaft 2b of the pivot 1 is inserted into the shaft hole 4h of the lower bearing 4b, and the upper pivot shaft 2a is brought into contact with the upper rail 3a while slightly lowering the lower pivot 1b. While keeping this state, the tip of the upper pivot shaft 2a is slid toward the end of the upper rail 3a while raising the door, and is slid on the slope 4s of the upper bearing 4a to push down the upper pivot shaft 2a toward the door d. Further, the upper bearing 4 is raised on the end side of the upper rail 3a.
The upper pivot shaft 2a is moved toward the shaft hole 4h toward the position a, and the upper pivot shaft 2a is fitted into the shaft hole 4h.

Thus, the upper and lower pivot shafts 2a and 2b of the pivots 1a and 1b are connected to the upper and lower bearings 4a and 4 of the rails 3a and 3b.
b, and the pivot door d can be attached to the opening frame b. So far, the closet door has been described as an example, but the present invention is not limited to this, and any door using a pivot can be used,
For example, it is possible to provide only a bearing in an opening frame without using a rail and use it for a hinged door such as an interior door or furniture, or a folding door such as a closet door or a movable partition.

[0031]

As described above, when the pivot 1 using the pivot shaft is attached to the opening frame b, the upper pivot shaft 2a is brought into contact with the upper rail 3a and the upper rail 4a is moved up to the upper bearing 4a at the end. Since the pivot shaft 2a can be moved and the upper pivot shaft 2a can be fitted into the upper bearing 4a with one touch, the installation work can be performed by itself, the work itself can be facilitated, and the workability is greatly improved. .

Further, since the stopper st is attached to the upper bearing 4a, the upper pivot shaft 2a is inserted through the shaft hole 4h of the upper bearing 4a.
The door d does not come off and the accident that the door d comes off from the opening frame b can be prevented.
