Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a wind regulator device suitable for automobiles and the like.

[Prior Art] Conventionally, as a wind regulator device for raising and lowering a wind panel along a guide rail,
For example, the one shown in Japanese Utility Model Publication No. 49-47623 is known.

That is, as shown in FIG. 5, a slider 105 is supported via a bracket 103 on a window panel 101 that can be moved up and down by a wire type regulator (not shown), and the slider 105 is attached to a door inner wall. It is adapted to roll in contact with a rail surface 109 of a guide rail 107 mounted on the panel.

[Problems to be Solved by the Invention] The guide rail 107 having such a configuration has the slider 1
05 is formed by a sliding rail surface 109 and a web surface 111 connecting this rail surface. The rail surface 109 on the window panel 101 side is approximately V
It has a letter-shaped cross-sectional shape and serves as a guide surface that guides the slider 105 along the surface without shifting. In addition, the web surface 111 and the slider 105
A desired clearance l is secured between the two.

If this clearance l is secured too large, there is a risk that the slider 105 may come off from the rail surface 109 on one side as shown by the chain line when an external force is applied to the wind panel 101 in the direction along the surface when the wind panel 101 is raised or lowered. Conversely, if the clearance l is small, the roller shaft 113
This caused problems such as interference with the slider, which created sliding resistance and made lifting and lowering movements heavier.

Therefore, an object of the present invention is to provide a wind regulator device that can smoothly raise and lower a wind panel even when an external force is applied not only perpendicular to the surface but also along the surface using a simple device. .

[Means for Solving the Problems] In order to achieve the above problems, the present invention provides a wind regulator that raises and lowers a wind panel equipped with a slider along a rail surface of a guide rail. In the device, the guide rail has a rail surface substantially parallel to the wind panel surface and a rail surface opposing the rail, and one rail surface of the guide rail is formed as a guide groove with a substantially V-shaped cross section. a first slider that is formed in a roller shape and rolls on one of the rail surfaces, while the other rail surface is formed in a planar shape, and the slider is formed in a roller shape; a second slider that rolls on the other rail surface and is biased toward the rail surface, connects one rail surface and the other rail surface of the guide rail, and When an external force in a direction along the wind panel surface is applied to either the web surface facing the side of the slider or the side of the slider facing this web surface, the web surface and A slider is provided with a smooth surface that abuts against the slider side.

[Operation] In this configuration, the roller-shaped slider rolls along the substantially V-shaped guide groove, so that the window panel can move up and down smoothly and correctly. On the other hand, when an external force along the surface is applied to the wind panel during elevation, the side surface of the slider comes into contact with the web surface, preventing it from separating from the guide groove, and the sliding resistance is kept small by the slider section. .

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 4.

In the figure, reference numeral 1 indicates a base plate fixed to the inner panel 5 of the door, and a pair of guide rails 7, 7 for guiding the window panel 5 in a vertically movable manner are attached to the plate 1. The guide rail 7 has rail surfaces 9a and 9b on which the first and second sliders 15a and 15b slide, and a web surface 11 that is perpendicular to the wind panel surface a and connects the rail surface 9a and the rail surface 9b. It is formed. A guide groove 13 having a substantially V-shaped cross section is formed along the longitudinal direction on the inner rail surface 9a facing the window panel 5.

The first and second sliders 15a and 15b are formed in the shape of rollers and are rotatably supported by a bracket 17 fixed to the window panel 5 via a rotating shaft 19, as shown in FIG. Panel 5
The inner rail surface 9a and the inner rail surface 9
a and the opposing outer rail surface 9b, respectively, and are able to roll. Outer rail surface 9b
The support bracket 21 supporting the central slider 15b in contact with the outer rail surface 9 is supported by a spring 23.
It is biased toward b (arrow side). As a result, the upper and lower sliders 15a come into strong contact with the inner rail surface 9a due to reaction, thereby preventing rattling in the direction perpendicular to the wind panel surface.

Further, when an external force F in the direction along the wind panel surface is applied to the first and second sliders 15a and 15b, the sliders 15a and 15b
A slider portion 25 is formed to reduce the sliding resistance between the side surface of the web surface 11 and the web surface 11.

The slider part 25 has a protruding part of the rotating shaft 19 protruding from the sliders 15a and 15b formed into a flange shape, and has a smooth surface 27 so as to make point contact with the surface facing the web surface 11. There is some clearance in between.

The slider portion 25 can also be formed by bulging the web surface 11 toward the side surfaces of the sliders 15a and 15b as shown in FIG. 2 (26 in the figure). The bulging surface facing the sliders 15a and 15b is a smooth surface 28. In this case, it is preferable that the rotating shaft 19 not protrude toward the side surface of the slider so that the sliders 15a, 15b and the slider portion 26 can smoothly contact each other.

The window panel 5 configured in this way is
It is guided by the guide rail 7 and moves up and down. In this case, the roller-shaped slider 15a is guided by the V-shaped guide groove 13 and rolls correctly and smoothly. On the other hand, window panel 5
When the external force F in the direction along the wind panel surface is applied to the wind panel 5 when the slider 1 is raised and lowered, the slider 1
The movement of the slider 15a is restricted by the contact between the side portion of the slider 5a and the web surface 11, and there is no possibility that the slider 15a will come off the guide groove 13. Furthermore, the slider portions 25 or 26 having a smooth surface do not generate any resistance that would restrict the sliding movement of the slider 15a.

Note that by covering the slider portion 25 with a synthetic resin cap, it is possible to further reduce the sliding resistance.

[Effects of the Invention] As explained above, according to the present invention, even if an external force is applied to the wind panel in the direction along its surface, the wind panel can be prevented from coming off the guide groove of the guide rail together with the slider. can. Moreover, the sliding resistance generated between the side portion of the slider and the web surface is suppressed to a small level, so that the wind panel can be smoothly raised and lowered without affecting the raising and lowering operation.
