Abstract

PROBLEM TO BE SOLVED: To impede rotation of a longitudinal shaft body at the time of mounting so as to prevent looseness of a height adjusting screw in a runner fixed to a door panel, with a plug provided at a longitudinal shaft body and a socket provided at a lateral shaft body as connecting elements. SOLUTION: A plug 14 of inverted T-shape formed of a longitudinal short shaft 14a and a lateral short shaft 14b is provided at the lower end of a longitudinal shaft body 11. A socket 17 formed of a suspension-holding hole 18 extended along an axis and an escape groove 19 of L-shape is formed at a shaft part of a lateral shaft body 12. After assembling the longitudinal shaft body 11 to a door panel P, the lateral shaft body 12 is assembled to the door panel P, and the plug 14 is engagedly caught by the socket 17. In the engaged state, the lateral short shaft 14b of the plug 14 of inverted T-shape is fixedly held and disabled from relative rotation by the suspension-holding hole 18. The longitudinal shaft body 11 is therefore hindered from being rotated at the time of opening/closing the door panel P, and a height adjusting screw can be hindered from getting loose.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension type runner applied to folding doors and sliding doors.

[0002]

2. Description of the Related Art A runner of the present invention is mounted on a door panel by using orthogonal plugs and sockets as connecting elements.
No. 13335 is known. In this case, as shown in FIG. 5, a vertical axis body 40 and a horizontal axis body 41 constitute an attachment portion, and a flat plate screw head-shaped plug 42 is provided at a lower portion of the vertical axis body 40. A socket 43 for catching and engaging the plug 42 is provided near the side end on the side. The socket 43 is formed by a vertical hole 43a that receives the large-diameter head of the plug 42 and that is perpendicular to the axis, and a circumferential groove 43b that is formed in the circumferential direction continuously from the vertical hole 43a.

In use, the horizontal shaft 41 is assembled on the door panel with the opening of the vertical hole 43a facing upward, and the vertical shaft 4
0 from the top side of the door panel, and the plug 42
Into the socket 43. Next, the horizontal shaft 41 is rotated, and the opening of the vertical hole 43a is directed downward, so that the plug 42 is retained and held.

[0004]

According to the above-mentioned runner mounting structure, the runner can be easily mounted on the door panel with one touch. Since the mounting structure is simple, the production cost of the runner can be reduced. The problem is vertical axis 4
0 also serves as a screw for height adjustment, and the plug 42 is freely rotatable with respect to the socket 43 in the mounted state, so that the longitudinal body 40 is easily loosened over time. . In particular, when the runner is applied to the folding door panel, the torsion moment acts on the longitudinal axis body 40 when the door panel is opened and closed, so that the runner tends to be loosened. In the folding door, since the vertical body 40 itself rotates relative to the door panel to absorb the relative displacement between the door panel and the runner, a large frictional resistance is generated between the vertical body 40 and the door panel. Easy to open and close the door panel smoothly.

An object of the present invention is to provide a suspension type runner which has a runner mounting structure using a plug and a socket as connecting elements, and can easily mount the runner to a door panel. Another object of the present invention is
