Description

[Detailed description of the invention] The present invention relates to a runner temporary fixing structure for a folding door. The runner mounting shaft 2 is rotatably inserted into the shaft hole 4 provided through the shaft hole 4 so that the upper end of the runner mounting shaft 2 protrudes, and a retaining portion 5 is formed at the upper end of the runner mounting shaft 2 to attach the runner to the door panel 1. 3, the temporary engagement body 6 is strong enough to be frictionally engaged with the runner mounting shaft 2 and easily destroyed by the rotational force of the runner mounting shaft 2 applied by the opening/closing operation of the folding door A. This is related to a temporary fixing structure for the runner of a folding door formed on the inner peripheral surface of the shaft hole 4 of the runner. To provide a structure for temporarily fixing a runner of a folding door, which can prevent the work of inserting the door into the rail from becoming troublesome due to the direction of the door being carelessly changed.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments. The folding door A is a bifold door in the embodiment,
It is constructed by connecting the inner sides of a pair of door panels 1 with each other through a hinge. A runner mounting portion 7 is provided protruding from the outside of each door panel 1, and a screw portion 9 for fixing the runner mounting shaft 2 is screwed into the screw hole 8 of the runner mounting portion 7 to secure the runner mounting shaft 2. It protrudes upward from the door panel 1. The runner mounting shaft 2 is made of metal, and the upper part of the runner mounting shaft 2 has a small diameter portion 1.
5. Reference numeral 3 denotes a runner, and a shaft hole 4 for the runner mounting shaft 2 is vertically penetrated through one end of a rectangular runner main body 11 that is elongated in the length direction of the rail 10. As shown in FIG. 5, small protrusions 13 are arranged circumferentially on the inner peripheral surface to form a temporary engagement body 6. When the runner mounting shaft 2 is inserted into the shaft hole 4, the outer periphery of the runner mounting shaft 2 is formed. The temporary engagement body 6 engages with friction. The strength of the temporary engaging body 6 is set to such a level that it is easily destroyed by the rotational force of the runner mounting shaft 2 applied when the folding door A is opened and closed. Reference numeral 14 denotes a retaining metal fitting which is fitted onto the small diameter portion 15 of the runner mounting shaft 2 protruding from the shaft hole 4 of the runner 3 to form the retaining portion 5 . FIG. 3 shows the operation of installing the folding door A onto the rail 10. Generally, the folding door A is folded and the runner 3 is inserted into the rail 10 in the direction of the arrow with the runner 3 protruding approximately at right angles to the door panel 1. It is mounted on the runner mounting shaft 2 in a state where it is approximately perpendicular to the panel 1. Therefore runner 3
The direction of the folding door A does not change, and the installation work of the folding door A becomes easier. When the folding door A is opened and closed after installation is completed, the temporary engagement body 6 is destroyed by the rotational force of the runner mounting shaft 2, and the inner peripheral surface of the shaft hole 4 of the runner 3 becomes smooth, and the temporary engagement body 6 opens and closes the door. There will be no hindrance to operation. still,
The temporary engaging body 6 may be located at the upper end or the lower end of the shaft hole 4 as shown in FIGS. 5b and 6, and the height position within the shaft hole 4 is not particularly limited.

FIG. 7 shows a temporary engagement body 6 formed from the burr 16, and FIG. 8 shows a temporary engagement body 6 formed from the soft layer 17.

As described above, the present invention is such that the runner mounting shaft protruding from the door panel is rotatably inserted into the shaft hole penetrated through the runner, the upper end of the runner mounting shaft protrudes, and the upper end of the runner mounting shaft is secured to prevent it from coming off. In the case where the runner is attached to the door panel, the temporary structure is strong enough to be frictionally engaged with the runner mounting shaft and easily destroyed by the rotational force of the runner mounting shaft that is applied when the folding door is opened and closed. Since the engaging body is formed on the inner circumferential surface of the shaft hole of the runner, when the runner is assembled to the runner mounting shaft of the door panel, the orientation of the runner will not change due to the temporary engagement body being regulated by the runner. This makes it easier to insert the runner into the rail, and the temporary engagement body is easily destroyed by the rotational force of the runner mounting shaft when the folding door is opened and closed after it is attached to the rail, so there is no problem in opening and closing the folding door. There is an advantage.
