Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a suspended wheel runner applied to a folding door or a sliding door.
[0002]
[Prior art]
The runner of this invention attaches a runner to a door panel using orthogonal plugs and sockets as connecting elements. This type of runner attachment structure is known in Japanese Utility Model Publication No. 6-13335. In this case, as shown in FIG. 5, the vertical axis body 40 and the horizontal axis body 41 constitute a mounting portion, and a flat screw head-like plug 42 is provided at the lower and lower sides of the vertical axis body 40. A socket 43 for capturing and engaging the plug 42 is provided near the side end. The socket 43 is formed by a vertical hole 43a that receives the large-diameter head of the plug 42 and is oriented perpendicular to the axis, and a circumferential groove 43b that is formed in the circumferential direction continuously to the vertical hole 43a.
[0003]
In use, the horizontal shaft body 41 is pre-assembled into the door panel with the opening of the vertical hole 43a facing upward, the vertical shaft body 40 is inserted from the upper surface side of the door panel, and the plug 42 is inserted into the socket 43. . Next, the horizontal shaft body 41 is rotated, and the plug 42 is retained and retained with the opening of the vertical hole 43a facing downward.
[0004]
[Problems to be solved by the invention]
According to the above runner mounting structure, the runner can be easily mounted on the door panel with a single touch. Since the mounting structure is simple, the production cost of the runner can be reduced. The problem is that the vertical body 40 also serves as a height adjusting screw, and the plug 42 can be freely rotated with respect to the socket 43 in the attached state. Is easy to loosen. In particular, when the runner is applied to a folding door panel, a torsional moment acts on the vertical axis body 40 when the door panel is opened and closed, so that looseness is likely to occur. In the folding door, since the vertical axis body 40 itself rotates relative to the door panel, the relative displacement between the door panel and the runner is absorbed, so that a large frictional resistance is generated between the vertical axis body 40 and the door panel. It is easy to open and close the door panel smoothly.
[0005]
An object of the present invention is to provide a runner-type runner having a runner mounting structure having a plug and a socket as a connecting element and capable of easily mounting the runner to a door panel.
Another object of the present invention is to provide a suspension type runner that can prevent the height adjusting screw from loosening, and therefore can always maintain the gap of the door panel properly.
Another object of the present invention is to provide a suspended-car runner that can be applied to sliding doors as well as sliding doors.
