<First embodiment>
As shown in FIGS. 1 to 5, the runner 1 of the curtain rail 100 is detachably attached to the curtain rail 100. As shown in FIG. A curtain is attached to the runner 1 , and the curtain can be opened and closed along the curtain rail 100 by moving the runner 1 along the extension direction of the curtain rail 100 . The mounting structure of the runner 1 to the curtain rail 100 is provided with the curtain rail 100 and the runner 1 .

As shown in FIGS. 1 and 2, the curtain rail 100 is made of metal or resin, for example. A rail groove 101 is formed in the curtain rail 100 at a position on the lower side when the curtain rail 100 is attached to a window frame or the like. The rail groove 101 is a portion into which the runner 1 is inserted and attached. The curtain rail 100 is formed so that the edges 102, 102 rise toward the inside, and the edges 102, 102 are positioned to face each other with a space therebetween. That is, the space formed between the edge portions 102 and 102 functions as the rail groove 101 . The distance between the opposing edges 102 , 102 (the width of the rail groove 101 ) is at least larger than part of the runner 1 .
The curtain rail 100 is formed such that a plate extending downward from above is folded back in front of the edges 102, 102 and curved, and the edges 102, 102 are formed so as to extend upward. there is The inner surface side of this curved portion functions as a placing portion 103 on which the ball 2 of the runner 1 is placed. The curvature of the mounting portion 103 is formed to have a smaller curvature than the curvature of the ball 2 .

As shown in FIGS. 1 to 5, the runner 1 is inserted into the rail groove 101 of the curtain rail 100, rotated 90 degrees, and attached to the curtain rail 100 so that the runner 1 can run freely along the rail groove 101. .
A runner 1 includes balls 2 and holders 3.
The ball 2 is made of metal, for example, and is sized to be freely inserted into the rail groove 101 . A pair of balls 2 are provided, for example, for one runner 1 , and each ball 2 is placed on a mounting portion 103 on the inner surface side of the curtain rail 100 and rolls on the mounting portion 103 . The ball 2 is formed to have a radius larger than the height from the mounting surface 103 of the ball 2 on the inner surface of the curtain rail 100 to the edges 102 of the rail groove 101 .
The holder 3 is made of, for example, resin, suspends the curtain, and holds the ball 2 . The holder 3 has a body portion 31 and a ball holding portion 32 .

The body portion 31 includes a columnar body 31a formed in the shape of a cylinder, a square column, or the like, and a hanging body 31b provided at one end of the columnar body 31a.

The accommodating portion 32a is formed so as to hold the ball 2 rotatably with a small gap therebetween. The accommodation portion 32a is formed, for example, so that at least half or more of the ball 2 can be accommodated therein.
The stopper 32b is formed to extend downward from the peripheral edge of the housing portion 32a. For example, two stoppers 32b are provided so as to face each other, and are formed to grip the outer surface of the ball 2. As shown in FIG. The stopper 32b is provided so as to face each other in a direction orthogonal to the rotation axis of the runner 1 and the extending direction of the ball holding portion 32 respectively. By pushing the ball 2 toward the accommodating portion 32a, the stopper 32b is slightly elastically deformed so that the ball 2 can be accommodated in the accommodating portion 32a.

Next, a method for attaching the runner 1 to the curtain rail 100 will be described.
When attaching the runner 1 to the curtain rail 100, as shown in FIG. 6, the runner 1 is held so that the longitudinal direction of the ball holding portion 32 of the runner 1 is along the rail groove 101 of the curtain rail 100, and the ball is held in that state. The holding portion 32 is inserted into the rail groove 101 .
Next, as shown in FIG. 7, the runner 1 is rotated 90 degrees around the axis of the main body portion 31 . As a result, the ball 2 held by the ball holding portion 2 is positioned above the placement portion 103 of the curtain rail 100 .

The runner 1 can be attached to the curtain rail 100 by the above operation.

As described above, since the runner 1 having the above structure has neither a wheel nor a shaft, it is not necessary to make the shaft thin by reducing the diameter of the wheel as in the conventional case. There is no lack of flexibility and there is no limit to the weight of curtains that can be hung.
Further, since the ball 2 is used instead of the wheel and the shaft, the runner 1 can be moved while the ball 2 is in surface contact with the mounting portion 103, so the running stability of the runner 1 is high. In particular, by forming the mounting portion 103 of the curtain rail 100 to have a smaller curvature than the curvature of the ball 2, the contact area between the ball 2 and the mounting portion 103 can be increased, and the runner 1 runs. Stability can be increased.
Also, since the ball 2 has a radius larger than the height from the mounting portion 103 of the ball 2 on the inner surface of the curtain rail 100 to the edges 102 of the rail groove 101 , the ball holding portion 32 is positioned at the edge 102 of the rail groove 101 . , 102, and running of the runner 1 is not hindered.
Further, since the ball 2 is rotatably accommodated in the accommodation portion 32a and is prevented from being detached by the stopper 32b, the running stability of the runner 1 can be enhanced.
Therefore, even if the runner 1 is installed after the curtain rail 100 is installed, the strength, durability, and running stability can be improved even with a so-called post-installation runner 1 .
