Description

[Detailed description of the invention] This invention relates to an improvement of a guide rail device for a sliding door for a vehicle. The purpose of this is to prevent the lower surface of the guide rail from expanding (deforming) by interposing a holder made of resin or the like.

The guide rail of a sliding door for a vehicle is provided in a steel part by cutting out the outer panel of the vehicle body, or by forming an emboss on the outer panel of the vehicle body and providing it within the embossment.

In the latter case, a gap was created between the embossment on the outer panel of the vehicle body and the guide rail for the following reason.

That is, (1) When the car body outer plate 1 is integrally recessed to form the embossment 2 in order to provide the guide rail 3 on the car body outer plate 1, the car body outer plate 1 is placed on the inside of the vehicle as shown in FIG. There is a limit to the depth of the embossing 2 when the guide rail 2 is recessed at right angles toward the guide rail 3, and it is difficult to form the embossing to a depth necessary for arranging the guide rail 3.

For this reason, as shown in FIG.
b is provided and integrally molded to obtain the depth of the embossing 2 necessary for arranging the guide rail 3.

Therefore, a gap 4 is created between both inclined surfaces 2 a and 2 b of the embossing 2 and the guide rail 3.

(2) In addition, the guide rail 3 is also made of roll-formed stainless steel for reasons of appearance and precision.
(for example, applying a patch).

(3) As mentioned above, there is a gap 4 between the embossment 2 on the vehicle body outer panel 1 and the guide rail 3, and it is difficult to reinforce the bending point A of the guide rail 3. As shown, the load F of the sliding door transmitted through the guide roller 5 is applied to the lower surface of the guide rail 3, and the bending point 4
A force that opens the lower surface of the guide rail 3 downward acts on the guide rail 3, deforming the guide rail 3. Therefore, countermeasures have been taken such as increasing the thickness of the plate.

6 is a part of a cover formed integrally with the guide rail 3 and covers the gap 4; 7 is a roller that receives a lateral load; 8 is a bracket attached to the door; 9 is a pin.

This invention eliminates the above-mentioned drawbacks.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

FIG. 1 is a side view of a vehicle having a sliding door a that is opened and closed in the longitudinal direction of the vehicle.A guide rail 13 is provided on the outer panel 11 of the vehicle body to guide a guide roller 5 provided on the sliding door a. ing.

FIG. 2 is an enlarged vertical cross-sectional view of the first embodiment taken along line I-I in FIG. There is.

The embossment 12 is an upper inclined surface 12a extending obliquely downward from the outer panel surface 11a of the vehicle body toward the inside of the vehicle interior.
, a side surface 12b extending substantially perpendicularly downward from the lower end 12d of the upper inclined surface 12a, and a lower end 12 of the side surface 12b.
A lower inclined surface 12a extends obliquely downward toward the outside of the vehicle from e.
, the side surface 12b and the lower inclined surface 12C are the vehicle body outer plate surface 11a.
It is continuous and integrally formed.

The embossing 12 has a depth and width that accommodate the guide rail 13, and the guide rail 13 is disposed within the embossing 12.

Further, the sliding door a is provided with a load roller 5 that receives the load of the sliding door a, which is a guide member, and a roller 7 that receives the load in the lateral direction, via a bracket 8 that is rotatably provided with a pin 9. A load roller 5, which is the guide member, and a roller 7, which receives a load in the lateral direction, are removably disposed within the guide rail 13 that supports and guides the guide member.

A holder 14 made of rubber, resin, or the like and having a substantially triangular cross section is interposed between the lower surface 13b of the guide rail 13 and the lower inclined surface 12C of the embossing 12.

The holding body 14 is held down by the lower flange 13a of the guide rail 13 so as not to move.

The holder 14 is provided with a through hole 1 for draining water that has entered between the guide rail 13 and the embossing 12.
9 is dawning.

The drain may also be a drainage ditch.

In the second embodiment shown in FIG. 3, a holder 14 is held on the lower surface of the guide rail 13 with an adhesive or an adhesive tape, and a contact portion 1 is provided at the lower corner of the guide rail 13.
6, it comes into contact with the holder 14 to prevent the holder 14 from moving.

In the third embodiment shown in FIG. 4, the holder 14 extends to the gap between the upper surface of the guide rail 13 and the upper inclined surface 12a of the embossing 12, and a molding 17 is provided on the holder 14 to improve the appearance. did.

In the fourth embodiment shown in FIG. 5, the shape of the holding body 14 is configured to have a vertical section so that the rear surface of the guide rail 13 and the outer plate 1 of the vehicle body are connected to each other.
The embossing 12 is sandwiched between the embossing 12 and the side 12C of the emboss 12 for individual identification.

18 is a mounting bolt/nut.

The holding body 14 of the present invention may be provided along the entire length of the guide rail 13, or may be attached at a pitch.

In this case, water is drained between the holders 14.

The holding body 14 is provided with a through hole 19 or a drainage groove for discharging rainwater, etc. that enters the back surface of the guide rail 13 (between the guide rail and the outer panel of the vehicle body), so that the holding body 14 is connected to the entire length of the guide rail 13. Even if the guide rail 13 is provided over a wide area, rainwater will not accumulate, and there is no risk of rust occurring or water entering from the mounting bolt/nut 18 portion of the guide rail 13.

In order to fix the holder itself to the outer panel of the vehicle body, a fixing device such as a bolt/nut, screw, or clip may be used instead of adhesive.

As described above, in this invention, a holder having a substantially triangular cross section is provided between the lower surface of the guide rail and the lower inclined surface of the embossment on the outer panel of the vehicle body, so that the guide rail can be held as shown in FIG.
The load F of 3 is transmitted to the 31st surface by the holding body 14,
The component force F' becomes the compressive force of 31, and F'' is the holder 14
and a frictional force at 31 and a force at 32 which applies a moment to the bending point 33.

Therefore, it is possible to prevent the bottom surface of the guide rail from opening (spreading) downward, and there is no need to take measures such as increasing the thickness of the entire guide rail or reinforcing parts, making processing and assembly easy. It is.

Since the load of the sliding door is not supported only by the mounting bolts, it is borne by the entire embossment (which is also supported by the entire rail and the holder on the bottom of the rail), and the strain on the outer skin of the car body due to the sliding door load is also affected by the plate thickness. This can be prevented without causing any problems.
