DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower fixing bearing such as a folding door or a partition door which is directly mounted on a floor or the like in order to be barrier-free, and an upper fixing which is fixed to an upper rail. It relates to a bearing bracket and the like.

[0002]

2. Description of the Related Art Conventionally, folding doors, partition doors and the like used for storage furniture such as clothes closets or storage fixtures such as closets, as shown in FIG.
The side edges of 0, 50 are connected to each other by hinges 51, 51 so as to be foldable, and upper rails 52 and lower rails 53 are respectively attached to upper and lower frame portions of the mounting frame. The upper and lower rails 5
Bearing brackets 54, 55 fitted to the rails 2 and 53 and fixed at predetermined positions on the rail by a fixing mechanism, and the upper and lower pivots of the folding door are rotatably supported by the bearing brackets 54 and 55, respectively. On the other hand, runners 56 and 57, which are movable along the upper and lower rails 52 and 53 in accordance with opening and closing, are attached to the upper and lower portions on the front side of the folding door so as to be openable and closable.

[0003]

According to the tendency of barrier-free in recent years, the lower rail 53 has a structure that does not protrude from the floor surface or a structure in which the amount of protrusion is small.
It is needless to say that it is desirable to provide a structure having no border on the floor surface without providing a lower rail for barrier-free. In this case, as a fixed support structure of the folding door, the bearing bracket is directly fixed to the floor surface, the pivot of the folding door is fitted and rotatably supported, and a hanging door wheel is mounted on the upper edge of the door end side. And a structure that runs on the upper rail is adopted.

However, in general, there is a manufacturing error in assembling accuracy of storage furniture and storage fixtures, and since the distance between the floor and the door is not constant, it is necessary to adjust the height between adjacent doors. Or the adjustment of the rotation axis position is often required. Of course, it is desirable from the viewpoint of workability that these adjustments can be performed with the folding door installed.

Therefore, a main object of the present invention is to make it possible to easily adjust the height of a folding door and the position of a rotating shaft in a state where the folding door is built, and to fix a lower part fixed directly to a floor surface. It is an object of the present invention to provide a bearing, an upper fixing bearing capable of firmly fixing the position with respect to the upper rail, and a positioning guide / side frame for installing the lower fixing bearing.

In addition, a preliminary hole 21d is provided at a position adjacent to the fixing screw mounting portion 21b for changing the fixing position in the future.
Are formed.

In the mounting operation of the folding door 1 by the lower fixing bearing 2 and the upper fixing bearing 3, first, the substrate 10 is fixed to the floor surface 6 by the first fixing screws 18. When fixing the substrate 10, as shown in FIG. 4B, it is desirable to mount the substrate 10 while using a side frame 25 mounted on the side of the mounting opening frame such as a folding door as a positioning guide. This positioning guide combined side frame 25
Is a projection 25a projecting inwardly formed at the end of the prospective surface 25c along the longitudinal direction of the member.
One end surface of the substrate 10 is brought into contact with the prospective surface 25c, and the step 2 formed by the projection 25a is formed.
The substrate 10 is positioned by attaching one corner end of the substrate 10 to 5b. By using such a positioning guide / side frame 25, the horizontal position adjustment and the front / rear position adjustment can be easily performed.

When the fixing work of the substrate 10 is completed, the folding door 1 is built. As shown in FIG. 2, the folding door 1 includes a lower end pivot 7 at a lower end of a door side, and an upper end pivot 8 at an upper end of the door side, and pivot shafts 7 a and 8 a are respectively connected to upper and lower portions. The mounting is performed so as to be fitted to the pivot receiving portions 13a and 20a of the fixing bearings 2 and 3.

In the horizontal mounting adjustment, the sliding body 12 of the lower fixing bearing 2 is slid in the left and right direction by moving the folding door 1 in the left and right direction, and the upper fixing bearing 3 is moved. This is done by moving in the rail direction. Incidentally, FIG. 5A is a diagram when the slide body 12 is moved to the door side, and FIG. 5B is a diagram when the slide body 12 is moved to the door side. The adjustment allowance is usually about ± 3 to 5 mm.

When the horizontal adjustment of the folding door 1 is completed and the positions of the upper and lower fixing bearings 2 and 3 are determined, the assembling screw 15 is first screwed into the lower fixing bearing 2. By doing so, the slide body 12 is immovably fixed, and the second fixing screw 17 is
The second screw through hole 12 c and the second fixing long screw hole 10 g of the substrate 10 are passed through and screwed into the floor surface 6 and fixed. Also,
For the upper fixing bearing 3, the fixing bolt 22 is turned to pinch and fix the horizontal protruding pieces 5 a, 5 a of the upper rail 5 with the position fixing fastening member 21 and the receiving metal body 20, and the position fixing fastening is performed. The fixing screw 23 is screwed through the fixing screw installation portion 21b of the member 21 and fixed firmly.

Next, the vertical mounting adjustment is performed by turning the vertical adjusting screw 14 of the lower mounting bracket 2 clockwise or counterclockwise to adjust the vertical position of the bearing member 13.

The present invention has been described above with reference to the example of the folding door 1.
The fixing brackets 2 and 3 can be similarly applied to a partition door or the like. Further, the lower fixing bearing 2 may be applied to the upper and lower ends of the door side of the hinged door.

[0030]

As described above in detail, according to the present invention, it is possible to easily adjust the height of the folding doors and the position of the rotating shaft in the state where the folding door is installed in the lower fixing bearing bracket directly attached to the floor surface. Will be able to do it. Further, it is possible to provide an upper fixing bearing which can be firmly fixed to the upper rail. Further, the use of the positioning guide / side frame makes it possible to accurately fix the lower fixing bearing member to the floor surface.
