DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a top pivot hinge for taking out and hanging according to the present invention will be described with reference to FIGS. First, the configuration will be described with reference to FIG. The take-out hanging top pivot hinge includes a pivot shaft device 10 attached to the upper end of the door D in an extended state and a pivot shaft holding device 20 attached to the upper side of the door frame W in an extended state.

The pivot shaft device 10 has a base end fitted into a concave portion formed at the upper end of the door D, fixed with screws 14, and a door-side hinge body 11 projects to the side of the door D. A bearing 13 is housed in a bearing receiving hole 11a recessed on the upper surface of the projecting end of the main body 11, a lower part 12a of the pivot shaft 12 is supported by the bearing 13, and is rotatable. The cover 15 projects upward from the door-side hinge body 11, and the cover 15 is fitted from below to the projecting portion of the door-side hinge body 11.

In the pivot shaft holding device 20, the door frame side hinge main body 21 has its base end fitted into a concave portion formed on the upper side of the door frame W, is fixed with screws 27, and projects to the side of the door frame W. And has a concave portion 21a facing the upper side of the door frame side hinge body 11 to receive the upper portion 12b of the pivot shaft 12 from the horizontal direction.
A hook 22 for holding the pivot shaft 12 received in the concave portion 21a of the door frame side hinge body 21 is pivotally mounted on a lower surface of the first frame 22 by a first pin 22e.
A stopper 23 is pivotally attached to the back surface of the second 2 by a second pin 23b. The holding plate 26 has the same shape as the projecting portion of the door frame side hinge body 21, and
The hook 22 and the stopper 23 are swingably sandwiched between the door frame 1 and the door frame 1 and are fixed to the door frame side hinge body 21 by screws 29. The hook 22 has two finger portions 22a, 22a.
b, the opening 22c between the fingers coincides with the recess 21a of the hinge body 21 on the door frame side in a plan view, and the upper part 12a of the pivot shaft 12 is received from the horizontal direction while rotating. Hugging 12 Stopper 23
Is pressed by a spring 24 to press the hook 22, and a step 23 formed at the tip of the stopper 23
When a is engaged with the stepped portion 22d formed on the back surface of the hook 22 in the assembled state, the locked state is established, and the rotation of the hook 22 is disabled. The cover 25 has a slit corresponding to the recess 21 a and is fitted to the door frame side hinge main body 21 from below to hide the holding plate 26 and the stopper 23.
The screw screw 28 is screwed into the door frame side hinge main body 21, and when screwed in, presses a projection 23 c formed on the stopper 23, and rotates the stopper 23 in a direction to compress the spring 24 to rotate the stopper 23. The stopper 23 can be separated from the hook 22 to release the engagement lock with the hook 22. Hold down 3
Numeral 0 is fitted in a lateral groove engraved on the pivot shaft 12 and fixed to the door frame side hinge main body 21 with a screw 31 so as to prevent the pivot shaft 12 from coming out of the concave portion 21a.

To suspend the door D, a pivot shaft device 10 is attached to the upper end of the door D as shown in FIG.
The pivot shaft holding device 20 is attached to the upper side of the door frame W. Then, as shown in FIG. 2A, a concave portion 21 a of the hinge body 21 on the door frame side of the pivot shaft holding device 20.
The door D is raised by aligning the bay 22c of the hook 22 with the pivot 22 so that the pivot 12 is relatively received in the recess 21a of the hinge body 21 on the door frame side.
2 is positioned corresponding to the open end of the concave portion 21a of the door frame side hinge body 21. Therefore, first, a take-out hanging pivot anchor shaft (not shown) attached to the lower end of the door vertical frame is fitted into a bearing hole of a lower pivot (not shown) attached to the lower end of the door, and then shown in FIGS. 2 (b) and 2 (c). By raising the upper end of the door D to the center of the thickness width of the door frame W as described above, the pivot shaft device 10 is moved to the pivot shaft holding device 20.
And the pivot shaft 12 of the pivot shaft device 10 is fitted into the concave portion 21 a of the hinge body 21 on the door frame side of the pivot shaft holding device 20 and the concave portion 22 a of the hook 22.
Then, the pivot shaft 12 rotates the hook 22, so that the bay portion 22 c of the hook 22 changes direction to make the pivot shaft 12 unable to escape, and the stopper 23.
Engages and locks the stepped portions 22d and 23a formed between the hook 22 and the back surface of the hook 22 to make the hook 22 unable to return to rotation, thereby completing the temporary fixing. Next, as shown in FIG.
When it is tightened and fixed in step 1, the hanging of the door D is completed.

In order to remove the door D, as shown in FIG. 3, when the screw 28 is closed after removing the holding member 30 first, the stopper 23 rotates in the direction to compress the spring 24, and Since the formed step portion 23a is separated from the step portion 22d formed on the back surface of the hook 22, the hook 22 can be returned to the rotation. So, door D
Door D to avoid interference with the side edge of the door frame W.
When the pivot shaft 12 is slightly opened and the upper end of the door D is strongly pushed in the direction of the arrow X in a direction in which the pivot shaft 12 escapes from the concave portion 21a of the door frame side hinge main body 21, the pivot shaft 12 returns and rotates the hook 22. As a result, the door frame side hinge body 21 escapes from the concave portion 21a. With the above operation, door D
Can be removed.

In short, according to the present invention, the door D is raised and the upper end of the door is raised to the center of the thickness of the door frame W, so that the concave portion 21a and the hook 22 The bay portion 22c is fitted with the pivot shaft 12 of the pivot shaft device 10 facing the same. Then, since the pivot shaft 12 rotates the hook 22, the bay portion 22 c of the hook 22 changes its direction to make the pivot shaft 12 unable to escape, and the stopper 23 engages and locks with the back surface of the hook 22. As a result, the hook 22 cannot rotate and return, and the temporary fixing is completed.

[0012]

As described above, according to the top pivot hinge for lifting and hanging according to the present invention, the pivot shaft holding device attached to the door frame is held closer to the pivot shaft attached to the door than in the horizontal direction. It can be temporarily fixed in the engaged state and then permanently fixed, so that the door can be easily hung alone.
