This is designed to be easy and reliable.

FIG. 1 shows a door glass elevating device for an automobile. A door glass 1 is provided between a door outer panel 2 and a door inner panel 3 so that it can be raised and lowered by a guide device described below.

A retaining plate 4 is attached to the center of the lower end of the door glass 1, and sliders 5, 6 are attached to the upper and lower ends of the retaining plate 4.
is installed.

Each of the sliders 5 and 6 has a vertical hole formed in its center, and a guide rail 7 is inserted through this hole to slidably grip the slider.

The guide rail 7 is formed of a pipe material, the upper end of which is crushed into a flat shape, and is attached to the door inner panel 3 with bolts 8.

Further, a bolt member 9 serving as a fastening member is integrally attached to the lower end portion by means described later, and is inserted into a portion bent toward the front in the figure at the lower end of the door inner panel 3 and tightened with a nut 10. There is.

This guide rail 7, the aforementioned holding plate 4, and sliders 5 and 6 form a lifting guide device 11 for the door glass 1.

A regulator device 12 is attached to the door inner panel 3, and an arm 14 is rotated by rotation of a handle 13 operated from the passenger compartment side, and the tip of the arm 14 applies a force in the vertical direction to the holding plate 4. The door glass 1 is raised and lowered.

Reference numeral 15 denotes a rail provided horizontally on the holding plate 4 for guiding the tip of the arm 14.

FIG. 2 shows a case where the elevating guide device 11 of FIG. 1 is lowered to the lowest position.

That is, a part of the lower end of the door inner panel 3 is bent toward the front, and the guide rail 7 is attached to this bent portion 16.
The lower end of the guide rail 7 is attached to the door inner panel 3 by inserting the male threaded part 17 of the bolt member 9 attached to the lower end of the guide rail 7 and tightening it with a bolt 10 via washers 18 and 19.

A flat part 2 is provided on the outer periphery of the lower end of the guide rail 7 so as to be parallel and perpendicular to the door glass 1 (see Fig. 1).
0 is formed.

The slider 6 is attached to the holding plate 4 by bolts 21, and a hole 22 is provided in the center of the slider 6, through which the guide rail 7 is slidably inserted (see Fig. 3). .

Reference numeral 23 denotes a damper member that comes into contact with the bent portion 16 of the door inner panel 3 to provide a damping effect when the door glass is lowered to the lowest position.

As described above, the guide rail 7 is attached to the door inner panel 3 by the bolt member 9 attached to its lower end, so the bolt member 9, which serves as a fastening member, must be attached to the lower end of the guide rail 7 by some means. Must be.

Here, the conventional mounting structure of the bolt member 9 to the lower end portion of the guide rail 7 will be explained with reference to FIGS. 4 to 9.

First, in the one shown in FIG. 4, the head 24 of the bolt member 9 is press-fitted into the lower end of the guide rail 7 and fixed thereto.

In this case, the installation work is relatively easy, but since the guide rail 7 receives a load in its longitudinal direction, it may warp or damage the outer surface of the guide rail during chucking. There is a problem.

Furthermore, since the diameter of the press-fitted portion becomes large, there is a problem in that if the sliders 5, 6 are forcefully fitted from this portion, the holes in the sliders 5, 6 will become larger.

In the one shown in FIG. 5, the head 24 of the bolt member 9 is inserted into the lower end of the guide rail 7, and then the flange portion 25 is fixed by welding.

In this case, there is a problem in that the outer diameter changes due to distortion of the material due to heat.

Furthermore, since the welded portion protrudes beyond the outer periphery, correction work is required, which is complicated.

Next, in the one shown in FIG. 6, the head 24 of the bolt member 9 is screwed into the lower end of the guide rail 7.

In this case, thread cutting is required and the work is complicated.

Also, chucking during processing may cause scratches.
Furthermore, there is a problem in that it is necessary to prevent loosening after tightening.

In the bolt shown in FIG. 7, the head 24 of the bolt member 9 is inserted into the lower end of the guide rail 7, and then the flange 25 and the lower end of the guide rail 7 are welded together by projection welding.

In this case, the flange portion 25 is provided with a circular or triangular projection 26 as shown in FIGS. 8 and 9.

In this case, spatter (
There is a problem in that a thin blade-like protrusion) occurs, which requires correction, and requires special equipment for welding.

This invention solves all of the various problems that these conventional methods had, and one embodiment thereof will be described below.

First, what is shown in FIG. 10 is a bolt member 9 that becomes a fastening member.
The head 24 of the head 24 is knurled to prevent rotation, and the one shown in FIG. 11 is serrated to prevent rotation.

Moreover, the parts shown in FIGS. 12 and 13 are partially flattened, and the parts shown in FIGS. 14 and 15 are hexagonal and each is processed to prevent rotation.

The bolt member 9 processed in this way is attached to the lower end of the guide rail 7, but it is better to form the flange portion 25 at the boundary between the head 24 and the male threaded portion 17 for more accurate positioning. The method of attaching the part 25 will be explained with reference to FIGS. 16 to 18.

As is clear from FIG. 16, the flange portion 25 has a slightly smaller diameter than the guide rail 7, and after the head 24 is inserted into the lower end of the guide rail 7, it is sandwiched from the outer periphery by molds 27 and 28. By applying pressure (see FIG. 18), the bolt member 9 is gripped and fixed in a state where this portion is reduced in diameter from the original outer diameter of the guide rail 7, as shown in FIGS. 16 and 17.

By processing in this manner, a flat portion 20 is formed on the outer periphery of the lower end portion of the guide rail 7.

FIG. 19 shows a nut 29 used as a fastening member for the guide rail 7.
This shows an example in which the nut 29 is held and fixed at the lower end of the guide rail 7, and the nut 29 is inserted into the lower end of the guide rail 7 and compressed from the outer periphery so that the inserted part extends to the end to form a flat part 20 and the diameter is reduced. It is.

This guide rail 7 is connected to the bent part 16 of the door inner panel 3.
When attaching the bolt to nut 2, insert the washer and attach the bolt to nut 2.
It will be screwed into 9.

Similar to that shown in FIG. 2, the plane 20 in FIGS. 16, 17, and 19 has been deformed under pressure so that it is parallel and perpendicular to the door glass.

In the guide rail 7, the diameter of the original part of the pipe material is the largest, the diameter of the flange part 25 is slightly smaller than this, and the diameter of the part reduced by forming the flat part 20 is smaller than the original diameter of the pipe material. becomes smaller.

Therefore, when inserting the guide rail 7 into the holes 22 of the sliders 5 and 6, the flange portion or the original part of the pipe material contacts and is guided by the holes 22, forming a flat surface 20 and reducing the diameter. The portion does not touch the hole 22.

Therefore, the guide rail 7 can be removed without damaging the inner surface of the hole 22.
can be inserted into the holes 22 of the sliders 5 and 6.

Further, the plane 20 is deformed under pressure so as to be parallel and perpendicular to the door glass 1.

During this pressurized deformation, the hole 22 is caused by the distortion of the guide rail 7.
Can be larger than about 45mm for door glass 1
Only in the diagonal direction of °.

Therefore, the inner surface of the hole 22 into which the guide rail 7 is inserted is likely to be scratched only in the diagonal direction where the door glass is held by the belt line and cannot move; Or the door glass parallel direction and vertical direction corresponding to the lateral direction will not be damaged.

Therefore, it is also possible to prevent the door glass 1 from vibrating in the longitudinal and lateral directions.

In the embodiment described above, the fastening member is attached to the lower end of the guide rail 7, but the invention is not limited to this, and depending on the mounting structure of the guide rail 7 to the door inner panel 3, the fastening member may be attached to the upper end. It is also possible.

In this invention, the guide rail 7 is formed of a pipe material, and at least one end thereof has knurling, serrations, etc.
Insert fastening members such as bolt members 9 and nuts 29 that have been subjected to anti-rotation processing such as polygon molding, and insert the inserted portion from the outer periphery of the pipe material so that the plurality of flat parts 20 are parallel and perpendicular to the door glass. The diameter of the inserted part is reduced by deforming it under pressure, and the insertion part can be inserted into the hole of the slider without contacting it, so that it can be slid by inserting the guide rail into the hole of the sliding member. When mounting the member on the guide rail, the insertion is easy, and there is no fear that the inner surface of the hole of the sliding member will be damaged by the end of the guide rail, and smooth sliding after assembly will not be impaired.

The fastening member is firmly attached to the guide rail, and there is no fear that the fastening member will rotate or come off when attached to the door.
