[0003]

[Problems to be solved by the device]

 In the above runner mounting mode, since the center of the screw shaft 34 and the side wall 38 of the mounting bracket 33 are fixed, the thickness center of the door panel 32 and the center of the screw shaft 34 are changed when the panel thickness changes. They cannot be located on the same plane. In other words, the door panel 32 is suspended in a state of being displaced in the thickness direction with respect to the guide rail, which is unsatisfactory in appearance. Of course, it is possible to prepare various kinds of mounting fittings 33 depending on the thickness of the door panel 32, but it is inevitable that the management thereof becomes complicated.

Depending on the variation in the formation position of the mounting hole 37, the side wall 38 of the mounting bracket 33 may float away from the main surface wall, or it may be difficult to mount the mounting bracket 33. The hole 37 needs to be formed.

An object of the present invention is to improve the relational structure between the mounting bracket and the female screw cylinder so that the door panel can be hung in an appropriate state even when the thickness of the door panel changes, and the thickness can be different. This is to obtain a runner with excellent versatility that can be commonly used for door panels.

[0006]

[Means for Solving the Problems]

 The runner of the present invention comprises a runner body 2 guided by a guide rail 1, a vertically elongated screw shaft 3 rotatably mounted on the runner body 2, and a mounting hole 19 provided in an upper end wall of a door panel 5. A female screw cylinder 4 that is inserted into the screw shaft 3 and screwed into the screw shaft 3, and a mounting bracket 6 that is screwed to the door panel 5 and presses and fixes the female screw cylinder 4 irremovably from the mounting hole 19. The upper wall 20 of the mounting bracket 6 for holding and fixing the female screw cylinder 4 is provided with a shaft insertion hole 23 for inserting the screw shaft 3, and the shaft insertion hole 23 is formed in the door panel 5. It is required to be formed in a long hole that is long in the thickness direction.

[0007]

[Action]

 If the female screw cylinder 4 and the mounting bracket 6 which are fitted into the mounting hole 19 are formed as independent parts and the shaft insertion hole 23 provided in the upper wall 20 of the mounting bracket 6 is formed as an elongated hole, the screw shaft 3, the mounting bracket 6 can be moved in the thickness direction of the door panel 5 while maintaining the relational structure among the three members, the female screw cylinder 4, and the mounting bracket 6, and any position within the slot of the shaft insertion hole 23 can be moved. In, the mounting bracket 6 can be fixed to the door panel 5.

[0008]

[Effect of the device]

 In the runner of the present invention, the mounting metal member 6 is adjusted and moved in the panel thickness direction with respect to the female screw cylinder 4 fitted in the door panel 5, and the female screw cylinder 4 can be fixed at that position, so that the panel thickness is large or small. Even if the thickness is different, the door panel 5 can be hung on the guide rail 1 in an appropriate hanging state in which the center of the thickness and the center of the screw shaft 3 match, and the runner is commonly used for the door panels 5 having different thicknesses. And its versatility can be improved. Even if there are variations in the positions where the mounting holes 19 are formed, the mounting brackets 6 can absorb the variations and mount the runners, so the runners can be easily mounted and the mounting holes 19 can be positioned with high positional accuracy. It is advantageous in that it need not be formed.

The runner body 2 has a screw shaft 3 at the center of the runner body 10. Is vertically passed through and the upper end is caulked and fixed. The screw shaft 3 is formed by integrally forming the pivot shaft 11, the hexagonal operation portion 12 in plan view, and the male screw portion 13, and fixing the rotation stopping piece 14 to the lower end of the male screw portion 13 by press fitting. The door panel 5 and the door panel 5 are connected via the female screw cylinder 4. By turning the operation portion 12 by twisting, the vertical distance between the guide rail 1 and the door panel 5 can be adjusted. A thrust washer 15 made of plastic is sandwiched between the operation portion 12 and the runner body 10.

The female screw cylinder 4 is made of a pipe material having a thread formed on the inner surface thereof, and as shown in FIG. 4, a quadrangle rotation stopper seat 17 is caulked and fixed to the upper end thereof, and the rotation stopper piece of the screw shaft 3 is fixed to the lower end of the cylinder wall. A groove 18 that engages with 14 is provided. The female screw cylinder 4 is inserted into a mounting hole 19 formed in the upper end wall of the door panel 5, and is fixed by a mounting bracket 6 so that it cannot be removed. The mounting hole 19 is formed on the center of the thickness of the door panel 5 by drilling.

In FIG. 2, the mounting member 6 is made of an inverted L-shaped metal plate having an upper wall 20 and a side wall 21 which are orthogonal to each other. The upper wall 20 has a plate surface center recessed upward so as to rotate the female screw cylinder 4. A seat receiving portion 22 that engages with the stop seat 17 is provided, and a shaft insertion hole 23 for inserting the screw shaft 3 is provided in the center of the seat receiving portion 22 in the left and right direction. In order to cope with the change in thickness of the door panel 5, the shaft insertion hole 23 is formed as a long hole in the panel thickness direction. Screw holes 24 are formed at the left and right ends of the upper wall 20 and at the four corners of the side wall 21, respectively. 25, the screw hole 24 on the upper wall 20 side is an elongated hole like the shaft insertion hole 23. 1 and 4, reference numeral 26 is a screw.

In the runner configured as described above, the male screw portion 13 of the screw shaft 3 is screwed into the female screw cylinder 4 through the shaft insertion hole 23, and the lower end thereof faces the lower end of the female screw cylinder 4 and is stopped.
