Abstract

PROBLEM TO BE SOLVED: To facilitate door stop or height adjusting work while a sliding door is being hung by hanging the sliding door via an elastic substance such as rubber on the slider of a rail provided on the top rail of an opening frame body. SOLUTION: An upper rail 2 is constructed by fixing the casing 9 of an rail on the top rail 4 of a frame body fitted in the inner periphery of an opening via a connecting tool 5, a rail base 6 and a U-shaped channel member 8. A connecting piece 12 is connected to a hanging metal fitting 3 attached to a slider 10 and fastened by a hanging bolt 13 and a nut 16 such that a rubber material 17 is slightly compressed by a U-shaped reinforcing member 15, and a sliding door 1 is hung via a U-shaped reinforcing member 14. In stead of the rubber material 17, a coil spring or a leaf spring may be used. Thus, by fastening with the bolt 13 while the sliding door 1 is hung, a gap between the lower end surface of the sliding door and a floor surface and inclination are adjusted. Also, when the sliding door 1 is shaken, the distortion of the connecting piece 12 or the hanging metal fitting 3 is prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging structure of a sliding door, and more particularly to a connecting structure of a hanging fitting and a sliding door.

[0002]

2. Description of the Related Art A sliding door suspended on an upper rail is used to open and close a frontage. This sliding door is provided with a suspension vehicle having rollers on both sides, and the suspension vehicle can be mounted on an upper rail to travel. Types of sliding doors include a manual opening and closing type, a semi-automatic type that automatically closes a manually opened sliding door, and a fully automatic opening and closing operation.
The structure for suspending the sliding door is basically the same.

By the way, as shown in FIG. 3, an accurite rail can be used as the upper rail (b) for suspending the sliding door (a). The accurlite rail is configured such that a slider (d) is loosely fitted in a long casing (c), and the slider (d) can slide along the casing (c). Therefore, so that the slider (d) can slide smoothly without resistance, the casing (c) and slider (d)
There are many small balls (e), (e) ... between them.

Therefore, the suspending metal fittings (f) and (f) attached to the upper end of the sliding door can be connected to the slider (d) to be hung, and the sliding door (a) moves as the slider (d) moves to move the frontage. Can be opened and closed. However, the accurite rail is a casing of small balls (e), (e) ...
Since there is an intervening force between (c) and the slider (d), if excessive force is applied, the balls (e), (e), etc. will not be able to rotate and a large resistance will occur, causing the slider (d) Movement is hindered.

On the other hand, the sliding door (a) has an appropriate gap left from the floor surface at its lower end, but the gap is adjusted by the influence of the mounting position of the accurlite rail. There is. Moreover, not only the clearance with the floor surface, but also the sliding door (a) is hung vertically, that is, the sliding contact (a) is adjusted so that it hits the door stop without any clearance.

FIG. 4 shows a conventional example in which the height of the sliding door (a) is adjusted, and a spacer (g) is provided between the sliding door (a) and the hanging metal fitting (f).
Is intervening. By adjusting the thickness of the spacer (g) appropriately, the clearance between the lower end of the sliding door (a) and the floor surface can be adjusted, and the spacer between the left and right hanging metal fittings (f), (f) and the sliding door (a) can be adjusted. It is possible to eliminate the gap with the door stop by adjusting the thickness of (g) and (g), but in this case, the sliding door (a) must be temporarily hung and the gap must be appropriate. For example, you have to remove it again and increase or decrease the number of spacers (g).

[0007]

As described above, when suspending a sliding door, there are the above problems. The problem to be solved by the present invention is this problem, and even when the accurlite rail is used as the upper rail, the accurlite rail can be smoothly opened / closed without being unreasonable. Provided is a structure for suspending a sliding door, the height and inclination of which can be adjusted while the sliding door is suspended.

[0008]

The form of the upper rail in the structure for suspending a sliding door according to the present invention is not limited, but when an accurlite rail is used, a hanging metal fitting is attached to the slider of the accurlite rail. The sliding door is hung. In this case, the hanging metal fitting is connected to the upper end of the sliding door via a hanging bolt and is not completely fixed. An elastic body is interposed between the upper end surface of the sliding door and the hanging metal fitting. The configuration is the same when a suspension vehicle is used.

The elastic body is rubber, spring, or the like, and the elastic body is in a compressed state by being interposed between the sliding door and the hanging metal fitting, so that an elastic force acts on the sliding door and the hanging metal fitting.
Of course, it does not come off because it is connected by the hanging bolt, but even if the sliding door is shaken by the pressing force acting on the sliding door surface, the elastic body is not deformed and the hanging metal fitting is not bent. Therefore, a bending moment does not act on the accurite rail, and only a vertical load acts so as not to force the slider, and the slider moves smoothly to open and close the sliding door. Moreover, the height and inclination of the sliding door can be adjusted by changing the degree of tightening of the suspension bolt. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an embodiment showing a vertical section of a sliding door suspension structure of the present invention. In FIG. 1, 1 is a sliding door, 2 is an upper rail, and 3 is a hanging metal fitting. And as the upper rail, the accurite rail is used. A rail stand 6 is attached to an upper rail 4 of a frame fitted on the inner circumference of a frontage via a connecting tool 5, and the rail stand 6 has a U-shaped channel member 8 and an upper rail 2, and opening and closing of a sliding door 1. The required control device is installed. In the present invention, this controller is irrelevant. A cover (not shown) is provided on the front side so that the cover can be opened and closed.

A support piece 7 is formed on the lower end of the rail base 6, and a U-shaped channel member 8 and an upper rail 2 are mounted on the support piece 7. By the way, since the upper rail 2 is an accurite rail and the slider 10 is loosely fitted in the casing 9 and a large number of balls 11, 11 ... Are interposed therebetween, the slider 10 has each ball 11, It is possible to move smoothly by rolling 11 ...

A hanging metal fitting 3 attached to the upper end of the sliding door 1.
Is attached to the slider 10, and the sliding door 1 can be moved with the movement of the slider 10 to open and close the frontage.
The hanging fitting 3 has a connecting piece 12 at its lower end, and the sliding door 1 is hung from the connecting piece 12 via a hanging bolt 13. At the upper end of the sliding door 1, a cross-section U-shaped reinforcing member 14 is provided with an opening at the top, and another U-shaped reinforcing member 15 is attached inside the U-shaped reinforcing member 14.

The hanging bolt 13 is screwed into a nut 16 fixed to a U-shaped reinforcing member 15 to suspend the sliding door 1. A rubber material 17 is provided between the connecting piece 12 of the hanging metal fitting 3 and the U-shaped reinforcing material 15, and the rubber material 17 is in a slightly compressed state. If the hanging bolt 13 is tightened, the rubber material 17 is further compressed, and the height and inclination of the sliding door 1 can be adjusted. Further, the rubber material 17 is accommodated in the U-shaped reinforcing material 14 and is covered by both side pieces 18 which stand upright. In this case, the surface material 19 attached to the surface of the sliding door 1 extends to the upper ends of the side pieces 18 of the U-shaped reinforcing material 14.

By the way, the rubber member 17 can be deformed by being sandwiched between the connecting piece 12 and the U-shaped reinforcing member 15. For example, when the sliding door 1 is shaken, the U-shaped reinforcing member 15 is replaced by the rubber member 17.
One side of is not compressed and the connecting piece 12 and the hanging metal fitting 3 are not bent. That is, the rubber material 17 absorbs the swing of the sliding door 1 and does not affect the hanging metal fitting 3 and the upper rail 2.

In the embodiment shown in FIG. 1, the rubber material 17 is interposed between the hanging fitting 3 and the sliding door 1, but a coil spring may be used instead of the rubber material. Figure 2 shows coil spring 2
0 is an embodiment using 0, the coil spring 20 is the connecting piece 12
And the U-shaped reinforcing material 15. Therefore, if the sliding door 1 is similarly tilted, one side of the coil spring 20 is compressed and the bending of the hanging fitting 3 is prevented.

The spring material is not limited to the above coil spring, and a leaf spring may be attached by sandwiching the hanging bolt 13, or a coil spring having a small diameter may be provided by sandwiching the hanging bolt 13. As described above, in the sliding door suspension structure of the present invention, the sliding door is hung with the hanging bolt on the hanging fitting, and the elastic body is interposed between the hanging fitting and the sliding door, and the following effects are obtained. You can

[0017]

Since the sliding door suspension structure of the present invention has an elastic body such as a rubber material or a spring material interposed between the hanging metal member and the sliding door, even when the sliding door is shaken by an external force. Absorb by deformation of the elastic body without bending the hanging metal fitting. Therefore, even if accurite rails are used as the upper rails, no bending moment acts on the accurlite rails, only vertical load acts and there is no overloading, and therefore smooth rolling without hindering ball rolling. You can open and close it.

Further, since the elastic body can be appropriately compressed by tightening a suspension bolt for suspending the sliding door, the height can be adjusted while the sliding door is suspended. Of course, the inclination of the sliding door can be eliminated by adjusting the tightening degree of the left and right suspension bolts, and the adjustment work for preventing a gap from being generated between the door stop is very simple.
