Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding wall guide rail used for partitioning a room, and a method for manufacturing the same, and more particularly to a curved guide rail and a tangential direction from one end on the outer diameter side to the other end. The present invention relates to a branched guide rail in which a curved guide rail extends and a method for manufacturing the same.

[0002]

2. Description of the Related Art A curved guide rail used for this kind of branched guide rail is a curved portion c of a guide rail b for guiding and suspending a sliding wall a as shown in FIG.
It is used for the sliding wall a and the curved portion c.
Since various guide rails that combine a curved guide and a straight guide are necessary so that the guide can be performed in a straight branch direction such as a virtual line, various considerations have been considered.

As shown in FIGS. 4 to 6, the curved guide rail has a substantially C-shaped lateral cross section. The rail flange portions d, d located at the lower stage support the runner e provided at the upper end of the sliding wall a from both sides. Further, the rail opening f formed between the rail flange portions d, d allows a hanging bolt g connecting the runner e and the sliding wall a to be loosely inserted. still,
Reference numeral h in the figure denotes a ceiling plate receiving flange portion, which is welded to the curved guide rail body.

Conventionally, such a curved guide rail is formed by casting because it has the above-mentioned substantially C-shaped cross-sectional shape and a complicated shape curved in the length direction.
Further, the rail flange portion d is formed to be thick in terms of strength.
Furthermore, there are various difficulties in combining a straight guide with this curved guide, and in some cases, various combinations are constructed.

[0005]

However, in the conventional case, even with a curved guide rail, there is a difference in shrinkage during cooling between the thick portion such as the rail flange portion d and the other thin portion, so that the shape is different. Distortion occurs. Therefore, there is a problem that the rail flange portion d is easily deformed into a twisted or inclined shape, and the sliding wall a during sliding is vertically moved or inclined. There is also a problem that a step is likely to occur at the joint between the curved guide rail and another guide rail, and the runner e is caught and the sliding wall a does not slide smoothly.

Further, since it is difficult to form a complicated shape such as a pair of ceiling plate receiving flange portions h, h on the left and right by casting, the ceiling plate receiving flange portion h is formed separately and curved. Since it has to be welded to the lower part of the guide rail body at two places on the left and right, there is a problem that the manufacturing cost of the curved guide rail by casting is further increased.

Further, it is more difficult to obtain precision in combining such a curved guide rail with a straight guide rail to form a branched guide rail, and even if it is carried out, great labor and cost are required.

An object of the present invention is to provide a sliding rail guide rail and a method for producing the same, which can solve the above problems.

Of the ceiling flange is the inner diameter surface, and the other surface is the flange protruding side is the outer diameter surface, and the inner and outer surfaces of the ceiling flanges have almost the same curvature. And the ceiling flanges of these curved members are butt-joined together with their inner and outer peripheral surfaces abutted to form a curved guide rail with a rail opening between the rail flanges. Then, on the upper and lower parts of one side, two straight extruded materials with ceiling flanges and rail flanges protruding in different sizes And butt joining in a state of combined abut the ceiling flange each other of mold material, forming a straight guide rail with a rail opening between the rails flange,

[0011]

In the above construction of the guide rail of the sliding wall of the present invention, each curved die member has a ceiling flange and a rail flange which are provided above and below the outer diameter side surface and the inner diameter side surface, respectively, and between the ceiling flanges. By having a butt joint structure in the, it is possible to satisfy the C-shaped cross-sectional shape and the required curved shape required for the curved guide rail of the sliding wall, and each curved mold member is Since it has a simple and left-right symmetrical U-shaped shape that only has ceiling flanges and rail flanges above and below the inner diameter side surface and the outer shape side surface, it is possible to apply what is easily and accurately obtained and bend it to the required shape.

Further, in the above construction of the method for manufacturing the sliding rail guide rail of the present invention, the ceiling flange and the rail flange are formed in a straight shape having the same sectional shape in which the ceiling flange and the rail flange project at different sizes. Since the extruded molding material of No. 2 is bent into a predetermined curved shape material, the cross-sectional shape of the same extruded molding material that is molded with high accuracy can be accurately maintained by high-precision bending processing that uses the guide of the roll. In addition, it is possible to accurately form two types of curved die members that are curved in the opposite directions such that the flange forming surface is the inner circumference and the outer circumference, and the inner circumference surface and the outer circumference surface formed by the ceiling flange have substantially the same curvature. By simply butt-welding these two types of curved flanges with their inner and outer peripheral surfaces in contact with each other, the two types of ceiling flanges can be welded together. The curved material can be integrally formed in a correctly aligned state, and a curved guide rail having an accurate cross-sectional shape and dimensions can be easily manufactured with high yield. Bending can be omitted, and those with accurate cross-sectional shapes and dimensions can be manufactured more easily and with good yield. Moreover, these curved guide rails and straight guide rails are adjacent to each other at one end and are straight. Guide

The ceiling plate receiving flanges 5a and 5b provided at the lower ends of the curved members 2a and 2b support the open ends of the ceiling plate.

In this embodiment, the ceiling plate receiving flange portion 5a,
Since 5b is formed integrally with the curved guide rail 1, it can be manufactured at a low cost, as compared with the case where the cast molded one has to weld the separately formed ceiling plate receiving flange portion to the curved guide rail body. You can Also, in FIG. 1, left and right 1
Welding to join the pair of curved mold members 2a and 2b is partially performed, but if all the abutting portions of the ceiling flanges 3a and 3b are welded or sealed with a sealing material or the like, scattering occurs between the ceiling plate and the slab. The scattered light generated can be prevented from leaking into the room through the gap between the abutting portions.

FIG. 3 shows the case of a branched guide rail according to the present invention in combination Jikajo guide rails 6 in the curved guide rail 1.

The straight guide rail 6 is made by using straight as-extruded straight shape members 7a and 7b which do not require bending, such as the curved shape members 2a and 2b of the curved guide rail 1, and both ceiling flanges 12a and 12b. What happened can the be manufactured by butt joining similarly to curved guide rail 1, the curved guide rail 1 and the straight guide rail 6, one
The guide rails 6 that are adjacent to each other and have straight guide rails 6 are curved.
Facing the drail 1 in the tangential direction, the other ends are separated from each other.
Then, in a state of facing each other, the dividing line joining edges 8a, 8b which can be formed with high accuracy by angling between the adjacent one ends of the curved mold material 2b and the straight mold material 7a which face each other are butt-joined to each other. With this, the curved guide rail 1 and the straight guide rail 6 are integrated at the secant joining portion 8 so as to have a highly accurate branched shape, and a branched rail-shaped guide rail can be easily manufactured with high yield. .
