[0003]

The wooden door panel is apt to warp and deform partly or wholly due to aging. Due to such deformation, in the case of a sliding door, for example, adjacent door panels abut and interfere with each other, which makes it difficult to open and close them, and there is a problem in putting them in and out of the door pocket. The deformed door panel needs to be replaced or extensively repaired, which is expensive in any case. Conventional runner units cannot handle the above situations. Further, when the door panel is suspended in the door frame and the finished dimensions of the door frame or door panel vary, adjacent door panels may rub against each other. There was a problem in that it was difficult to obtain construction quality.

An object of the present invention is to provide a lateral adjusting mechanism for adjusting the hanging posture of the door panel in the panel thickness direction, and by changing and adjusting the hanging posture of the door panel by this adjusting mechanism, the door panel can be adjusted. An object of the present invention is to provide a runner unit that can be opened and closed without any hindrance even when warped. Another object of the present invention is to provide a horizontal adjustment mechanism and a vertical adjustment mechanism, and it is possible to easily adjust the vertical and horizontal directions when suspending a door panel, and therefore, adjust the suspension posture of the door panel at a construction site. Another object is to provide a runner unit that enables easy maintenance after construction. Another object of the present invention is to provide a runner unit capable of easily performing adjustment operations of vertical and horizontal adjustment mechanisms at one end of a door panel. Another object of the present invention is to provide a runner unit which can be easily assembled and can be easily attached to a door panel at a construction site.

[0005]

A runner unit according to the present invention comprises a runner main body 3, a runner base 5 for supporting a runner shaft 4 provided on the runner main body 3, and a runner base mounted inside the door panel 1. And a housing 6 for housing and holding 5. A lateral adjustment mechanism for adjusting the position of the door panel 1 in the thickness direction is provided between the housing 6 and the runner base 5. The lateral adjustment mechanism includes a lateral adjustment shaft 33 rotatably supported by the housing 6, and a motion conversion mechanism that converts the rotational motion of the lateral adjustment shaft 33 into a motion in the thickness direction of the door panel 1 and transmits it to the runner table 5. It consists of. In the above runner unit, a vertical adjustment mechanism for vertically operating the runner shaft 4 is provided inside the runner base 5. The vertical adjustment mechanism is a vertical adjustment shaft 28 rotatably supported by the runner table 5.
