Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a guide device for raising and lowering an automobile window glass, and in particular to an improvement of a guide roller that slides while fitting into a guide rail of the guide device.

[Prior art]

In the conventional guide device, as shown in FIG. 2, the roller shaft 5 is assembled into the guide roller 4 and then fixed to the support 3 of the window glass by caulking. In such a structure, if the roller diameter (B dimension) is made smaller, the shaft diameter (C dimension) of the caulked portion with the support body becomes smaller, which hinders compactness.

[Problem that the invention attempts to solve]

In view of the above-mentioned problems, the object of this invention is to provide an automobile window glass guide device in which the diameter of the rollers and the cross section of the guide rail are made compact.

[Means for solving problems]

The automotive window glass guide device of this invention has a guide roller attached to one end of the window glass fitted to the inner surface of a guide rail with a U-shaped cross section that is fixed inside the vehicle window. In an automotive window glass guide device that raises and lowers a window glass, the roller shaft has a flange at one end of the shaft portion, and the flange is brought into contact with a side piece of a support that holds the window glass. is fixed to the side piece of the support body, a guide roller having a hat-shaped cross section is rotatably fitted to the shaft portion of the roller shaft, and the cylindrical portion of the guide roller is attached to the opposing wall surface of the guide rail having a U-shaped cross section. The flange of the guide roller is slidably fitted on the inner surface of the guide rail, and the flange of the guide roller is brought into contact with an outward flange provided on one of the opposing wall surfaces of the guide rail.

〔Example〕

An embodiment of this invention will be explained with reference to the drawings. 1st
The figure is a front view of the mounting part of the window glass guide device. 1 is the window glass, 2 is the guide rail, and 3 is the support for the window glass. A roller shaft 5 is fixed to the support 3, and the roller shaft 5 is used for guiding. Fitting and supporting the roller 4,
A guide roller 4 is provided on the inner surface of the guide rail 2.
is fitted in a slidable manner. Specifically, in FIG. 3, 5 is a roller shaft, and a collar 52 is formed at one end of a shaft portion 51, and a protruding shaft portion 53 is formed on the end surface of the collar 52.
A convex portion 55 is formed at the other end of the shaft portion 51 so as to be continuous with the groove portion 54 . Reference numeral 3 denotes a support body for holding the window glass 1, and the shaft portion 53 of the roller shaft 5 is fitted into a hole 33 formed in a side piece 32 bent at right angles to the window glass support surface 31, and the flange is inserted into the hole 33. 52 to side piece 3
2, and the roller shaft 5 is fixed by caulking, welding, or the like. 4 is a guide roller made of synthetic resin formed into a hat-shaped cross section, and the cylindrical portion 4
A hole 43 is bored in the bottom surface 42 of 1. Therefore, if the cylindrical part 41 of the guide roller 4 is rotatably fitted to the shaft part 51 of the roller shaft 5, the convex part 55 of the roller shaft 5 will fit into the hole 43 bored in the bottom surface 42 of the guide roller 4. They are press-fitted and sandwich the groove 54 of the roller shaft 5, and the flange 44 of the guide roller 4 comes into contact with the collar 52 of the roller shaft 5, so that the guide roller 4 is pivotally attached to the roller shaft 5 without coming off. be done. Reference numeral 2 denotes a guide rail that is fixed inside the vehicle under the window, and has wall surfaces 22 and 23 extending at right angles to both sides of a bottom surface 21 to form a U-shaped cross section. In FIG. 3, the free end of the wall surface 22 is bent outward at a substantially right angle to form a flange 24, and when the guide roller 4 is inserted into the inner surface of the wall surfaces 22, 23 of the guide rail 2, the flange A flange 44 comes into contact with 24 to constitute a window glass guide device that regulates the position of the window glass in the left and right and front and back directions. FIG. 4 shows another embodiment of this invention, in which the roller shaft 6 has a collar 62 at one end of the shaft portion 61, and a convex portion 64 connected to the groove portion 63 at the other end.
is formed, and the shaft portion 61 is inserted into the hole 33 bored in the side piece 32 of the support 3 of the window glass 1, and the flange 62 is inserted.
is brought into contact with the side piece 32 of the support body 3, and the roller shaft 6 is fixed.

This invention is based on the above-mentioned structure, and the roller shaft 5 can be fixed to the support body 3 in advance,
If the guide roller 4 is inserted into the roller shaft 5,
The flange 44 contacts the collar 52, and the guide roller 4 can be attached to the roller shaft 5. Moreover, if the guide roller 4 is fitted into the inner surface of the guide rail 2 and the flange 44 of the guide roller 4 is brought into contact with the flange 24 of the guide rail 2,
It is possible to regulate the position of the window glass in the left-right and front-back directions. In addition, since the flange 24 of the guide rail 2 is provided only on either the wall surface 22 or 23 of the U-shaped cross section, the contact resistance with the flange 44 of the guide roller 4 is alleviated, and smooth vertical sliding is achieved. can be done.

According to this embodiment, as is clear from FIGS. 3 and 4, the roller shaft can be fixed by its collar, which allows for a large contact surface (dimension D) with the support, so that external forces (thrust direction, shear direction, bending moment). In particular, the caulking portion can be prevented from coming off or deforming due to bending moments by making the D dimension large. Further, the size C of the caulked portion can be selected without being influenced much by the roller diameter B.

[Effect of idea]

This automotive window glass guide device has a guide roller attached to one end of the window glass fitted to the inner surface of a guide rail with a U-shaped cross section that is fixed inside the vehicle window. In an automobile window glass guide device that raises and lowers glass, the roller shaft is supported by having a flange at one end of the shaft portion, and the flange of the roller shaft is brought into contact with a side piece of a support that holds the window glass. A guide roller having a hat-shaped cross section is rotatably fitted to the shaft portion of the roller shaft, and the cylindrical portion of the guide roller is attached to the inner surface of the opposing wall of the guide rail having a U-shaped cross section. The flange of the guide roller abuts the outward flange provided on either side of the opposing wall of the guide rail, which is an extremely simple structure, and the diameter of the guide roller and cross section of the guide rail are compact. In addition to making it possible to
This has the advantage that the contact resistance between the guide roller and the guide rail can be alleviated.
