Embodiments of the folding door runner auxiliary member according to the present invention will be described below with reference to FIGS. 1 to 3.

In this embodiment, one end of a rectangular parallelepiped block base B supporting wheels A rolling on a box-shaped rail R is projected in a rectangular shape in the longitudinal direction of the rail R. The application is for a folding door runner equipped with an extension C. In this folding door runner, a base B and a support member D fixed to a door plate P are rotatably connected by a support shaft E.

As shown in FIG. 1, this embodiment is provided with a rectangular parallelepiped block-shaped main body 1 formed of a synthetic resin material or the like and extending in the length direction of the rail R.

At one end of the main body portion 1, a rectangular mounting port 2 which is fitted and removed from the extension portion C is opened. At the other end of the main body portion 1, saw-tooth-shaped concave-convex portions 3 in which concaves and convexes having peaks and valleys of approximately 90 degrees are arranged on both sides in the width direction of the rail R are formed. Between these mounting ports 2 and the uneven portion 3,
The inside of the main body 1 has a horizontally elongated hollow through the through hole 4.

Further, on the upper surface of the main body portion 1, there is provided a mark 5 made of the character "upper" which clearly indicates the top and bottom.

According to this embodiment, as shown in FIG. 2, by fitting the mounting opening 2 into the extension portion C,
For the protrusion length b from the extension C of the main body 1, the extension C
It will be a more extended form. Therefore, as shown in FIG. 3, the interval a between the runners can be further extended to secure a larger opening / closing movement angle θ, and the door plate P can be opened / closed in a more stable posture.

When the door plate P is opened and closed, as shown in FIG. 3, the concavo-convex portions 3 abut against each other and mesh with each other, whereby the rail R
The positional deviation between the runners in the width direction of the rail R is corrected, and the rails are aligned on the straight line R extending in the length direction. Therefore, the stable posture of the door plate P during opening and closing is maintained.

Since the main body 1 is provided with the mark 5, the top and bottom of the extension C will not be mistaken when it is attached. For this reason, the engagement of the uneven portion 3 described above does not become impossible.

Further, at the time of hitting the uneven portion 3 described above,
Since the inside of the main body 1 is hollow, the impact force and impact sound at the collision are attenuated.

Further, in this embodiment, it is possible to prevent the dead space from becoming large by removing the door plate P from the extension portion C when the door plate P is folded and stored.

As described above, in addition to the illustrated embodiment, it is possible to prepare a plurality of types having different extensions of the rail R of the main body 1 in the length direction, and select and use them appropriately. .

Further, the uneven portion 3 can be formed in a corrugated shape, a square shape, or the like.

Further, it is also possible to embed the magnets in the main body 1 and to attract each other to prevent repetition of collision and separation to prevent impact of collision.

Furthermore, although the mounting portion has been described on the premise of the mounting opening 2, the fitting structure between the extension portion C and the mounting opening 2 may be replaced and implemented.

Further, although the description has been made on the premise that the opening 2 and the punched hole 4 have different hole diameters, it is possible to secure the fitting margin of the extension portion C with the same hole diameter, and in this case, the same. The hole diameter may be a slight taper hole so as to prevent the hole from coming off.

[0029]

As described above, in the folding door runner auxiliary member according to the present invention, the mounting opening is fitted to the extension portion of the folding door runner.
By attaching them together, the protrusion length from the extension is extended and extended.
Between the runners as the long part is further extended
The gap is further extended to ensure a large opening and closing angle , and when opening and closing the door plate, the uneven parts at the tips of the protruding lengths mesh with each other to correct the positional deviation, so even if the door plate is extended It has the effect of opening and closing in a stable posture.

Furthermore, since the door plate can be detached when it is folded and stored, there is an effect that a large dead space can be avoided.
