JPH09264088A - Suspension structure of slide door using accuride rail (accurate slide rail) - Google Patents

Abstract

PROBLEM TO BE SOLVED: To ensure a smooth opening/closing operation by arranging a suspension metal fitting journalled to a shaft at a slider, interposing an elastic member in the suspension metal fitting and the slider, and making a plane containing balls arranged upward and downward of the slider correspond to the center of sliding door. SOLUTION: A rail base 6 is mounted on an upper beam 4 of frame fitted in the inner circumferential of frontage by means of an interconnector 5, an U-shaped channel member in which an upper rail 2 being an ACCURIDE RAIL (R) (accurate slide rail) is fitted is mounted on a support metal fitting 7 of L shape in section mounted on a lower end of the rail base 6. In a casing 9 of the upper rail 2 a slider 10 is loosely fitted, and between them a plurality of balls 11... are interposed. A suspension metal fitting 3 mounted on an upper end of a sliding door 1 is mounted to the slider 10, and the sliding door 1 is moved in association with the movement of the slider 10. A rubber plate 12a is interposed between the fitting 3 and the slider 10 while a rubber plate 12b is placed on the outside of the metal fitting 3 and they are screw fixed through a washer 13. Accordingly, even if the door 1 swings to a some extent the bend of the fitting 3 is absorbed by the plates 12a, 12b, thereby alleviating the external force applied to the slider 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door suspension device using an accurite rail, and more particularly to a connecting structure between the rail and the 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.

[0005]

As described above, when the accurlite rail is used as the upper rail for suspending the sliding door, there are the above problems. The problem to be solved by the present invention is this problem, and it provides a hanging structure of a sliding door that does not force the accurlite rail and enables a smooth opening / closing operation.

[0006]

The hanging structure for a sliding door according to the present invention uses an accurlite rail as an upper rail, and a hanging fitting is attached to the slider of the accurlite rail to attach the sliding door. It is hanging. In this case, the hanging metal fitting is not completely fixed to the slider, and has a mounting structure that can be slightly bent by an external force applied to the surface of the sliding door.

The hanging metal fitting extending upward from the sliding door is connected to the shaft provided on the slider while being pivotally supported.
An elastic body such as a rubber plate or a spring is interposed between the slider and the hanging metal fitting so that the bending of the hanging metal fitting does not affect the slider. That is, the structure is such that the elastic body is not deformed to force the ball of the accurite rail and the rotation of the ball is not hindered. 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. A rail stand 6 is attached to the upper rail 4 of the frame fitted on the inner circumference of the front through a connecting tool 5, and the rail stand 6 has a support fitting 7 having an L-shaped cross section.
A U-shaped channel member 8 and a control device required for opening and closing the sliding door 1 are attached. In the present invention, this controller is irrelevant. And the front side is equipped with a cover that can be opened and closed.

The support metal fitting 7 is attached to the lower end of the rail base 6, a U-shaped channel member 8 is attached on the support metal fitting 7, and the upper rail 2 is fitted in the U-shaped channel member 8. . 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 moves smoothly. You can

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.
Here, the hanging metal fitting 3 is attached to the slider 10,
A rubber plate 12a is interposed between the slider 10 and the hanging fitting 3 instead of being in a completely fixed state. Similarly, a rubber plate 12b is also provided on the outside of the hanging metal fitting 3, and is screwed via a washer 13. Therefore, even if the sliding door 1 is slightly shaken, the bending of the hanging metal fitting 3 is caused by the rubber plate 12 described above.
The external force exerted on the slider 10 due to the compressive deformation of a and 12b is relaxed.

Here, a hole is formed in the hanging metal fitting 3, and the shaft 14 is inserted into this hole and screwed.
There must be some clearance between the holes. The elastic body interposed between the hanging metal fitting 3 and the slider 10 is not limited to the rubber plate 12, and a disc spring can be used. Also, the coil spring can be loosely fitted on the shaft.

FIG. 2 shows an embodiment in which a disc spring is used instead of the rubber plate. A disc spring 15a is provided between the slider 10 and the hanging metal fitting 3, and a disc spring 15 is provided outside the hanging metal fitting 3.
b is attached, and both disc springs 15a and 15b are provided with hanging metal fittings in between. Therefore, even when the hanging metal fitting 3 is bent as in the case of the rubber plate, the disc spring is deformed and an unreasonable external force does not act on the slider 10, so that the balls 11, 11 ... I can't be disturbed.

As described above, the hanging structure of the sliding door according to the present invention uses the accurlite rail as the upper rail, and the hanging metal fitting is screwed to the slider of the accurlite rail and the elastic body is interposed. These are connected, and the following effects can be obtained.

[0014]

In the sliding door of the present invention, since the accurlite rail is used as the upper rail, it suffices to attach the hanging metal fitting to the slider, and the structure is simple as compared with the case of using the hanging vehicle equipped with the rollers. Is. The hanging metal fitting for suspending the sliding door is connected to the slider of the accurite rail, but it is not completely fixed and an elastic body such as a rubber plate is interposed between the hanging metal fitting and the hanging metal fitting. It is possible. Therefore, the suspension metal is bent by the deformation of the elastic body, so that no moment acts on the slider and the rolling of the ball is not hindered, so that the sliding door can be opened and closed smoothly. Further, since the planes including the balls arranged above and below the slider are suspended so as to coincide with the center of the sliding door, only a vertical load acts on the upper rail and no moment is generated.
