Abstract

PURPOSE:To provide a precision guide rail in divergent form through a simple procedure with a good yield from production line. CONSTITUTION:Two straight members produced by extrusive shaping process where ceiling flanges 3a, 3b and rail flanges 4a, 4b are protruding in different sizes at the top and bottom of one of the surfaces, are formed through a roll flexing process in such directions that the surface on the flange projecting side becomes the inside surface and that it becomes the outside surface. The ceiling flanges having the same curvature of two curved shapes 2a, 2b produced thereby are butted to each other and joined so that a curved guide rail 1 having a rail opening 9 is formed, and a straight guide rail 6 is formed in the same manner through omission of only the flex processing. Split line joining edges 8a, 8b formed between the curved shape 2b and a straight shape 12a of respective members as confronting one another are butted together and joined so that the straight guide rail extends in the tangential direction on the outer side of the curved guide rail from a one-end curved base part of the rail 1 to its other end, and thereby the two guide rails 1, 6 are consolidated and turned in a divergent rail form.

Description

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.

[0009]

There are straight shaped members having flanges above and below the inner diameter side surface and the outer diameter side surface, respectively, and the cross-sectional shapes are bilaterally symmetrical, and each of them is a straight shape. Each of the ceiling flanges is in contact with each other and has a butt joint that is butt-joined to each other, and is composed of a straight guide rail having a rail opening between the rail flanges, and the straight guide rail is outside the curved guide rail. On the radial side, one end of the curved guide rail is extended tangentially to the other end of the curved guide rail so that the curved rails and the straight rails have a secant joint between the curved rails and the straight rails. It is characterized by being integrated.

According to the method of manufacturing a guide rail of the present invention, one of two straight extrusion-molded materials in which the ceiling flange and the rail flange are projected to different sizes in the upper and lower portions of one surface, and the surface on the flange protruding side is The inner surface and the outer surface formed by the ceiling flanges have the same curvature by roll bending in the direction that becomes the inner diameter surface and the other in the direction that the surface on the flange protruding side becomes the outer diameter surface. As a shape material, the ceiling flanges of these curved shape materials are butt-joined together with their inner and outer peripheral surfaces abutting against each other to form a curved guide rail with a rail opening between the rail flanges. Two straight extruded products with ceiling flanges and rail flanges protruding in different sizes are attached to the upper and lower parts of the Butt joints in the state of contacting each other to form a straight guide rail with a rail opening between the rail flanges, and the straight guide rail bends at one end of the curved guide rail on the outer diameter side of the curved guide rail. The curved guide rails and the straight guide rails are butt-joined to each other so as to extend in the tangential direction from the base portion to the other end of the curved guide rails, and the secant joining edges formed between the opposing curved die members and straight die members are joined together. It is characterized by being integrated into a branch rail shape.

By having the mating joint structure, 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 die member has its inner diameter. Since it has a simple and left-right symmetrical U-shape that only has a ceiling flange and a rail flange on the top and bottom of the side surface and outer shape side surface, it is possible to easily and accurately obtain what is required and to obtain the required curved state. The curved guide rail can be configured accurately, and the straight rail does not have to be curved, so it is easier and more accurate and accurate than the curved guide rail. These curved guide rails and straight guide rails have curved line members facing each other and secant line joints between the straight line members, and the secant line joint edges of this part are also accurate by angle cutting of each die member. Since the guide rail is formed easily and easily, a highly accurate guide rail in which a curved guide rail and a straight guide rail are combined in a branched shape can be easily and inexpensively obtained.

Further, in the above construction of the method for manufacturing the guide rail of the present invention, a straight extruded material having the same cross-sectional shape in which the ceiling flange and the rail flange project in different sizes at the upper and lower portions of one surface is roll-bent. Since it is processed into a predetermined curved mold material, by highly accurate bending using the guide of the roll, the cross-sectional shape of the same extrusion molded material that is molded with high accuracy can be maintained accurately, and the flange forming surface It is possible to accurately form two types of curved die members that are the inner and outer peripheries and are curved in the opposite directions in which the inner and outer peripheral surfaces of the ceiling flange have substantially the same curvature. Ceiling flanges,

On the other hand, the curved member 2b on the right side in the drawing is provided with a ceiling flange 3b and a rail flange 4b on the inner diameter side surface 2d in a position and orientation symmetrical to the curved member 2a. Further, the ceiling plate receiving flange portion 5b is also formed by the curved member 2a on the left side.
It is provided at a position and orientation symmetrical to the ceiling plate receiving flange 5a.

The curved mold members 2a and 2b are obtained by roll-bending a straight extrusion molding material having the same cross-sectional shape.

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 a case where a straight guide rail 6 is combined with the curved guide rail 1 to form a branched guide rail according to the present invention.

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. The curved guide rails 1 and 6 can be manufactured by butt-jointing the curved guide rails 1 like the curved guide rails 1. The straight guide rails 6 are curved guides on the outer diameter side of the curved guide rail 1. The rail 1 can be formed with high accuracy by angling or the like between the curved die members 2b and the straight die members 7 facing each other so as to extend in a tangential direction from one end curved base portion to the other end side of the curved guide rail 1. The curved guide rail 1 can be formed simply by butt-joining the split line joining edges 8a and 8b.
The straight guide rail 6 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.
