Description

[Detailed Description of the Invention] This invention relates to a guide tube fixing device that guides the windshield for an automobile and sets its up-and-down locus when the windshield is raised and lowered during opening and closing.

Examples of conventional guide tube fixing devices for door glass include those shown in FIGS. 1 to 4.

1 and 2 show how the guide tube 1 is installed, and the guide tube 1 is brought into direct contact with the mounting surface 2a formed at the lower end of the door inner panel 2 during panel molding. It is attached to the upper end of the inner panel via a bracket 3 so as to be adjustable in the vehicle width direction X.

A slider 4 is slidably attached to the guide tube 1, and a door glass 6 attached to the slider 4 by adhesive or bolts 5 moves up and down along the guide tube 1.

The slider 4 is attached to the lower end of the door glass 6, and in order to support the door glass 6 so that it does not swing, two sliders 4 are used at a slight interval in the figure.

The vicinity of the mounting surface 2a against which the lower end of the guide tube 1 comes into contact is shown in detail in FIGS. 3 and 4.

In FIG. 3, the mounting surface 2a is formed as an inclined surface on the lower surface of the inner panel 2, and has a hole 2b formed therein.

A hollow protruding glue retainer 7 projects through the hole 2b and is attached by welding 8.

The lower end of the guide tube 1 is inserted into and fixed to the outer periphery of the retainer 7 via a packing 9 made of rubber, for example, in order to prevent moisture and metal-to-metal contact.

On the other hand, FIG. 4 shows another example in which the guide tube 1 is shaped by directly processing a threaded portion 10 at its tip or by attaching a separate part. For example, a flat rubber gasket 11 is attached to the guide tube 1. It is sandwiched between the mounting surface 2a of the inner panel 2 and protrudes through the hole 2b, and a washer 12 is inserted into the protruding threaded portion 10 and is secured by tightening with a nut 13.

Therefore, since the distal ends of the guide tubes 1 are fixed via the gaskets 9 and 11, they have a slight degree of freedom with respect to inclination, and this degree of freedom allows the guide tubes 1 to be adjusted in the vehicle width direction.

Incidentally, there is a technique very similar to such a conventional technique as disclosed in Japanese Utility Model Application Laid-Open No. 53-90323.

However, in such a conventional guide tube fixing device, the inner panel itself is provided with a mounting surface perpendicular to the guide tube and a hole into which the retainer or threaded part is inserted, and the guide is inserted through the packing. Since the tube 1 was configured to be fixed, the mounting surface processing part was visible from the indoor side and was unsightly, and the retainer 7 and threaded part 10
Since the insertion hole is opened, there is a risk of water entering the room unless it is completely sealed with not only the gasket but also other sealants, such as vinyl chloride sheet material.
There was a problem in that workability was poor because of the welding work and the tightening work of the nut 13.

This invention was made by focusing on the problems of the conventional guide tube, and includes a guide having a mounting surface perpendicular to the axis of the guide tube and a retaining section protruding from the mounting surface and extending into the guide tube. It is an object of the present invention to solve the above-mentioned problems by fixing a tube support bracket to an inner panel to form a lower guide tube attachment structure.

This invention will be explained below based on the drawings.

FIG. 5 is a diagram showing an embodiment of this invention, and in the figure, members that are the same or equivalent to those shown in FIGS. 1 to 4 are designated by the same numbers and their explanations will be omitted.

First, to explain the structure, the guide tube support bracket 14 is a molded product of a steel plate or resin, and has a mounting surface portion 14a that is approximately perpendicular to the central axis of the guide tube 1, and is provided protruding from the mounting surface portion 14a. It has a retaining portion 14b that extends into the guide tube 1.

The guide tube support bracket 14 is a separate component from the inner panel 2, and is fixed to the door inner panel 2 at a flange portion 14C by welding, adhesive, or the like.

Generally, the collar 15 absorbs variations in the inner diameter of the guide tube 1 and variations in the outer diameter of the retaining portion 14b, eliminates rattling that causes abnormal noise during driving, and improves the width of the guide tube 1 in the vehicle width direction X. To enable position adjustment,
For example, it is made of rubber and is fitted onto the outer periphery of the retaining portion 14b or the guide tube 1.

The guide tube 1 is fitted into the retaining portion 14b of the guide tube support bracket 14 via the collar 15.

The lower end of the guide tube 1 is fixed by attaching the guide tube support bracket 14 to the locking portion 14b via the collar 15.
The upper part is fixed with a conventional adjustable bolt as shown in Figure 2, and the guide tube 1 is inserted into the guide tube 1.
By moving the upper end in the vehicle width direction X, the lower end changes its inclination using the locking part 14b as a fulcrum, changes the axis of the guide tube 1, and adjusts the vertical locus of the door glass.

As explained above, according to this invention, there is no hole or mounting surface provided at the lower end of the inner panel itself, so there is no need to seal that part, and the appearance is improved, as well as the need for brackets. Easy to automate resistance welding (
For example, spot welding) can be performed, and the guide tube can be fixed downward simply by inserting the end into the retaining part, resulting in extremely good workability.

Further, since the retaining portion has a bullet-shaped shape as in the embodiment, the guide tube can be inserted smoothly.
