Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a window glass support device for a wind regulator.

[Prior Art] Generally, in the case of a wire-type wind regulator, a wire is connected to a bracket that supports the window glass, and the wire is wound around a wire drum connected to a power-type or manual-type drive device. ing. Therefore, as the wire drum rotates forward or backward, the bracket moves up and down while being guided by a guide rail disposed along the up-and-down locus of the window glass.

A conventional guide rail 101 that guides a windshield in the vertical direction includes, for example, left and right side rail surfaces 10 facing in the vehicle width direction X, as shown in FIG.
5, 105 and a guide rail surface 103 facing in the front-back direction Y. It is formed in a C-shaped channel shape. The guide rail 101 has a guide rail surface 1
An elastic body 107 that is in elastic contact with 03 and each side rail surface 105, 105 is biased by the elastic body 107.
A slider 113 made of synthetic resin is slidably disposed in contact with a guide surface 111 in which a dovetail groove 109 is formed. Note that the slider 113 is supported by a bracket shaft 115.

The elastic body 107 having such a configuration secures the desired contact pressure on the slider 113 so that the bracket shaft 11
This prevents the window glass supported by 5 from rattling due to vibrations during driving. in this case,
If a molding error occurs in the guide rail 101 and the slider 113, a gap will occur between the guide rail 101 and the slider 113 and each rail surface. A gap in the width direction X can be absorbed by the elastic body 107, but a gap in the longitudinal direction Y appears as looseness. On the other hand, since the elastic body 107 is made of a material such as rubber, it tends to wear out easily, and if used for a long period of time, it will wear out and its biasing function will deteriorate. When the biasing function deteriorates, backlash will occur in the width direction of the vehicle, and this play may increase over time. Further, in order to form the slider 113 so that it properly contacts each rail surface, high machining accuracy is required, and the contact of the slider 113 wears out over time, resulting in the formation of gaps.

[Purpose of the invention] Therefore, the invention provides a window glass support device for a wind regulator that ensures reliable contact pressure over a long period of time and enables stable vertical movement.

[Structure of the invention] In order to achieve the above object, in this invention, the guide rail of the wind regulator has a pair of side rail surfaces facing in the width direction of the vehicle and a guide rail surface facing in the front-rear direction. formed in a channel shape and perpendicular to the guide rail surface,
and a first slider rotatable about the axis of the shaft as a fulcrum, and a second slider rotatable in a direction orthogonal to the first slider, on the bracket shaft of the bracket supporting the window glass. The first slider has a pair of cam parts in contact with each side rail surface and an elastic tongue part in elastic contact with the rail surface, and the second slider has a pair of cam parts in contact with each side rail surface, and a second slider has a pair of cam parts in contact with each side rail surface, and an elastic tongue part in elastic contact with the rail surface. It has a structure including a cam part that comes in contact with the rail surface and an elastic tongue part that comes into elastic contact with the rail surface.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 2 to 9.

In the figure, 1 indicates a door consisting of a door inner panel and an outer panel, and 3 indicates a window regulator, which includes a central bracket 9 that supports a window glass 5 via a carrier plate 7 and a direct support The front and rear brackets 9, 9 (left and right in FIG. 2), the guide rails 11, 11, 11 for guiding the brackets 9 along the upward and downward locus of the windshield 5, and the carrier plate 7 are connected to each other, and wire drum 1
3 and the wire drum 13
The guide rail 11 is fixed to the inner panel of the door 1. As a result, each bracket 9 is guided by the guide rail 11 and moves up and down as the wire 15 rotates (arrow A) due to the forward or reverse rotation of the wire drum 13.

The guide rail 11 includes a guide rail surface 21 facing in the longitudinal direction Y, side rail surfaces 19, 19 facing the vehicle width direction X, and a regulating surface 25 facing the guide rail surface 21 and having a dovetail groove 23 formed in the longitudinal direction. A first slider 27 and a second slider 29 are disposed within the rail 11, which has a C-shaped channel shape in cross section. The first and second sliders 27 and 29 are made of a material such as synthetic resin, and are spherical portions 31 of a bracket shaft 31 whose axis P is perpendicular to the guide rail surface 21.
It is fitted in a. Threaded portion 3 of bracket shaft 31
1a protrudes from the dovetail groove 23 and is screwed onto the bracket 9.

On the other hand, the first slider 27 has arc-shaped cam portions 33, 33 in line contact with the respective side rail surfaces 19, 19.
and the elastic tongue portion 3 in elastic contact with the rail surfaces 19, 19.
