DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pivot for supporting a door so that the door can be freely opened and closed, and more particularly to a slide-type pivot capable of easily hanging the door.

[0002]

2. Description of the Related Art As a hinge mechanism for supporting a door so that it can be opened and closed, for example, a top pivot as shown in FIG. 5 has been developed and used. The top pivot is, the door side Pivot 1 00 attached to the door top, the door side Pivot 1 00
And a frame-side pivot 101 attached to the door frame side corresponding to the lower shaft (not shown) of the door closer 103 provided at the lower part of the door in a fitting hole (not shown) of the receiving seat 102 attached to the floor side. After inserting and-fitted substantially) been raised the door 104 is lowered to the shaft 101A of the frame side pivot 101, the shaft 101A of the door side pivot 1 00 Sha
So that the Komu hanging and is fitted to shift the receiving hole.

[0003]

However, in the case of such a top pivot, when the door is suspended, a screw provided on the frame-side pivot is turned to lower the shaft. Since the arm is extended from the lower side to the upper frame side to perform the screwing operation, there are inconveniences such as difficulty in performing the operation. Moreover In such a top pivot is because the shaft is unlikely to visually fitted state the door side Pivot directly fraught danger such door fall down not be confirmed whether the shaft has been fitted into .

[0004] In view of the above circumstances, the present invention provides a slide-type pivot capable of easily performing a hanging operation of a door, achieving good workability, and realizing a safe and reliable hanging operation. The purpose is to provide.

[0005]

That is, according to the present invention, a pair of substantially U-shaped holding members provided on a door frame side and having notches for gripping a door shaft are provided. A door-side pivot that extends in the horizontal direction and is fixed to a corner of the door that is cut out in a substantially rectangular shape with one of the holders opened in a shaft receiving hole formed between the holders. Was

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2
1 shows a sliding pivot according to the present invention, in which a pair of holding members 3A and 3B having a substantially U-shaped
To the side frame-side pivot 2 and its holding body 3
The shaft 6 sandwiched between A and 3B is pivoted to the door 4 on the door 4 side.
Includes the bets 5, also retaining body 3A, both these unexpected out during 3B are a fixing screw 7 for fixing (open unexpected) as attached.

A lower shaft, which is inserted and fitted into a fitting hole of a seat mounted on the floor, is attached to a lower portion (not shown) of the door 4 of this embodiment. Further, the lower shaft is provided as a part of a center suspension type door closer provided inside the door, but the closer does not need to be particularly the center suspension type. Good. In the case of a simple door which does not require a closer function, it is not necessary to provide the center suspension type door closer.

As shown in FIG. 4, the holding body 3A has a substantially semicircular notch 31 on one side and a groove 32 along the horizontal direction on the side having the notch 31. The other holding body 3B is rotatably attached to the groove 32 portion.
On the other hand, the holding body 3B has a substantially semicircular notch 33 formed on the side opposite to the holding body 3A, and is opened and closed by a rotating shaft 3C provided in the stationary holding body 3A. Mounted freely. As shown in FIG. 1, the holding body 3B is provided with a recess 34 which is a part of the stopper means on the base end side where the rotating shaft 3C is mounted. On the other hand, the holding body 3A has
When the holder 3B is closed, the holder 3B
B is a groove 3 into which a protrusion 35 for temporarily fixing B and a spring 36 pressing the protrusion 35 are slidably inserted.
2 at a predetermined position.

As shown in FIG. 3, the shaft 6 is integrally fixed to the door 4 by appropriate means, and a metal bearing 61 is rotatably mounted concentrically on the outer peripheral surface. There shaft 6 is made to allow smooth rotation relative to the retaining member 3A, 3B that sandwich the bearing 61 provided on the outer peripheral surface of the shaft 6 when the opening and closing. In FIG. 3, the bearing 6 provided on the outer peripheral surface of the shaft 6 is shown.
The diameter of the shaft head is formed larger than the diameter of the bearing 61 so that 1 does not come off the shaft 6. The means for rotatably attaching the shaft to the holding body is not particularly limited to this metal bearing, and various suitable bearings and the like can be applied. The fixing screw 7 inserts the shaft 6 from the side between the opened holding members 3A and 3B, closes the holding member 3B, and then screws into the screw hole 38 of the holding member 3B, and It is designed to be fixed together. In addition, the fixing means of the present invention is not limited to this screw, and any suitable means can be applied.

Next, the operation of this embodiment will be described with reference to FIG. First, the work of hanging the door 4
The operation is performed while the door 4 is tilted obliquely and the lower shaft protruding from the lower part of the door 4 is locked in the fitting hole on the floor surface side. In this case, the holding body 3B is rotated outward with respect to the holding body 3A to open the holding body 3A (turned clockwise in FIG. 4).

Here, the door 4 into which the lower shaft is inserted is slowly raised toward the vertical state. At this time, the shaft 6 of the door 4 is substantially inserted into the notch 31 of the holding body 3A which is opened. Insert from the side in the horizontal direction. And that shi
When the raft 6 is inserted, the holder 3B is rotated so as to close to the holder 3A. If it is completely closed in this way (by this, both holding bodies 3A,
Death composed of shaft receiver hole in the notches 31 and 33 of 3B
The shaft 6 is rotatably supported), and the projection 35 is fitted into the recess 34 of the holder 3B from the holder 3A side, so that a temporary stopper state of the holder 3B is realized. I do. The screw 3 is then screwed into the screw hole 38 to securely fix the holder 3B to the holder 3A. Finally, for example, the door 4 is opened, and the holding body 3 is exposed.
A portion including A and 3B is covered with an appropriate decorative cover 30 formed in advance.

[0012]

As described above, according to the present invention, a shaft provided with a bearing on the outer peripheral surface is provided at one corner of one of the doors (the side serving as the rotation center at the time of opening and closing).
On the corresponding door frame side, at least one is provided with a holding body (having a shaft supporting function) rotatable in a horizontal direction,
And confirmed directly quite easily and eyes only to fix the retaining body inserted a shaft provided with a fixing screw for clamping the bearing provided on the shaft outer circumferential surface, thereby simply slide the shaft in the horizontal direction and inserted Since the hanging operation of the door can be realized, there is no need to turn the face or the arm directly upward to perform a troublesome screwdriver or the like, and a slide pivot that has good workability and is safe and secure is provided. be able to.
