Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an automobile sliding door mounting device that facilitates the installation of a sliding door in an automobile using a sliding door.

[Prior art]

In a cab-over type automobile as shown in Figure 1, the front door 1 has a structure in which the front end is supported by a hinge (not shown), but the rear door has a sliding door 2. It is designed to open and close by sliding against the vehicle body 3. The sliding door 2 is supported by the vehicle body at its upper and lower portions and at its center, and the lower part of the support structure includes:
There were still problems to be solved with the current version.

To explain this with reference to FIG. 2, which shows a cross section along the - line with the sliding door 2 of the automobile in FIG. 1 closed, 4 is a floor panel, and 5 is a section following this floor panel 4 This is a lower step (see Figure 1). A roller arm 6 is located at the bottom of the step 5 and protrudes inward from the bottom of the sliding door 2 located outside the step 5. A main roller 8, which receives the load of the sliding door 2, is rotatably supported in a vertical plane by a horizontal shaft 7 on the roller arm 6.

A separate roller arm 9 is attached to and integrated with the roller arm 6 to which the main roller 8 is attached by two bolts 10 and 11. These bolts 10 and 11 pass through round holes 12 and 13 drilled in the roller arm 9 located above, and are screwed into female threaded holes 14 and 15 cut in the roller arm 6 located below. Two roller arms 6 and 9 are fixed. The roller arm 9 includes a guide roller 16 that maintains the posture of the sliding door 2.
is rotatably supported in a horizontal plane by a vertical shaft 17.

The main roller 8 rolls on a base 18 located below the step 5, and the guide roller 16 rolls on a U-shaped guide rail 1 provided on the underside of the step 5.
It is designed to roll in contact with either the left or right side of 9. 20 is a weather strip attached to the base 18.

In the conventional sliding door mounting device having such a configuration, when the sliding door 2 is mounted on the vehicle body 3, it cannot be assembled with the roller arm 9 attached to the roller arm 6. Attach the sliding door 2 to the vehicle body 3 without attaching it, and then move the guide roller 16 to the second
As shown by the chain line in the figure, the roller arm 9 is attached to the roller arm 6 by passing through it from below and positioning it inside the guide rail 19. Therefore, in actual work, it is necessary to change the hand that was supporting the sliding door 2 to hold the roller arm 9, which causes a loss of man-hours.

[Purpose of invention]

The purpose of this invention is to solve such problems with conventional sliding door mounting devices and to enable easy mounting of a sliding door.

[Structure of the idea]

The automobile sliding door mounting device of this invention is
A guide rail is provided at the bottom of the floor panel or a step following the floor panel, and a base is provided at the bottom of the guide rail, and two roller arms protruding from the sliding door are pivoted to the guide rail and the base. In an automobile in which a plurality of rollers are engaged, one roller arm is formed with a round hole and a long hole, the other roller arm is formed with a female screw hole and a hole, and the round hole is formed with a female screw hole and a hole. inserting a bolt and screwing the bolt into the female threaded hole and tightening;
A crimping pin is inserted into the elongated hole and the crimping pin is crimped into the hole.

〔Example〕

Next, an embodiment of this invention will be explained with respect to the figures from FIG. 3 onwards, with the same members as in FIGS. As shown, one roller arm 9 to which the guide roller 16 is attached has a round hole 12 and a long hole 21, and the other roller arm 6 to which the main roller 8 is attached has a female screw hole 14 and a hole 23. It has been drilled. A caulking pin 22 is inserted into the long hole 21 and caulked into the hole 23 of the roller arm 6, so that the roller arm 9 is slidably attached to the roller arm 6.

In this device configured in this way, the roller arm 9 is slidably attached to the roller arm 6 using only the caulking pin 22, the roller arm 9 is fully pulled out as shown in FIG.
The sliding door 2 is tilted so that the sliding door 6 is positioned at the bottom of the guide rail 19. and guide roller 1
6 into the guide rail 19, raise the sliding door 2 as shown in FIG.
is slid against the roller arm 6 in the direction of retraction. Then, in the final position shown in FIG. 6, the bolt 10 is inserted into the round hole 12, screwed into the female threaded hole 14, and tightened to complete the installation work. Note that when tightening the bolt 10, the position of the sliding door 2 can be slightly adjusted within the range of a slight difference in diameter between the round hole 12 and the bolt 10.

[Effect of idea]

This invention is based on the elongated hole 21 of one roller arm 9.
Since the two roller arms 6 and 9 are pre-assembled temporarily by caulking the caulking pin 22 inserted through the hole 23 of the other roller arm 6, it is difficult to assemble the roller arm 9 to the roller arm 6 during the assembly work. Since there is no need to attach the roller arm 9 and there is no need to drop the roller arm 9, assembly work becomes easier.

Furthermore, when attaching the slide door 2 to the guide rail 19, simply by tilting the slide door 2, the roller arm 9 will incline in the direction of engagement with the guide rail 19 due to its own weight, making it easy to attach the slide door 2. If the round hole 12 and the female threaded hole 14 match, the rough adjustment of the position of the sliding door 2 is automatically completed, and then screw the bolt 10 into the female threaded hole 14 and adjust the bolt 10 while making fine adjustments to the sliding door 2. Since the position of the sliding door 2 is determined by tightening, the position of the sliding door 2 can be easily adjusted, and the conventionally used shim for position adjustment becomes unnecessary.
