<Prior Art> Conventionally, as this type of window glass lifting guide device for an automobile door, the one shown in FIGS. ).

In this conventional example, when the window glass 3 of the automobile door 2 is guided up and down by the sash 1, the outer surface 4 of the sash 1 and the outer surface 5 of the window glass 3 are placed on the same plane (flush surface formation). It is intended to improve aerodynamic characteristics, wind noise reduction characteristics, and design by providing a smooth outer surface, and according to this, the grooves 8.9 for guiding the upper and lower sashes 6 and lower sashes 7 for raising and lowering each is the inner surface 10 of the window glass 3
offset state (inward in the vehicle width direction (direction of arrow A)
The window glass 3 is raised and lowered by sliding the slider 11 in each groove of the upper and lower sashes 8.9 via the glass run 12. You will be guided.

The slider 11 is formed in a cross-sectional shape by the fixing part 15 and the guide part 16, and is located at both the front and rear ends 17 and 18 of the window glass 3, and in the window glass lifting direction (up and down in FIG. 10). direction). The guide portion 16 of the slider 11 is formed in an offset state inward in the vehicle width direction with respect to the inner surface 10 of the window glass 3 over its entire length, and is used for guiding up and down the upper and lower sashes 6.7. They correspond to the grooves 8.9, respectively. Furthermore, 19 in the figure is a door panel, 20
21 represents a door outer panel, 21 represents a door inner panel, 22 represents a door lock, and 23 represents a weather strip. Further, arrow B indicates the front side.

<Problems to be Solved by the Invention> However, in such a conventional automobile door window glass elevating guide device, firstly, the groove portion 9 for elevating and lowering the lower sash 7 is not connected to the inner surface of the window glass 3. 10 is formed in the same offset state as the groove 8 for guiding the upper sash 6 up and down, and as a result, the rear end 18 of the window glass 3 is located inside the automobile door 2 and does not enter into the lower sash 7. When the water 24 adhering to the window glass 3 flows down along the window glass 3, it drips down from the lower end of the window glass 3 and especially the rear end 1 of the window glass 3.
If the water that has fallen through the door lock 22 hits the door lock 22, there is a risk of adverse effects such as "grease flow" or "freezing".Secondly, the window glass 3 is directly supported by the sash 1. Because it is supported via the slider 11, if a force in the vehicle width direction is applied to the window glass 3 due to sudden opening and closing of the automobile door 3, suction of the window glass 3 during high-speed driving, etc., the slider 1
1, and in order to withstand the burden, the momentum slider 11 is increased in size, the length of the slider 11 is increased, and the amount of riding increases accordingly, reducing the operability of raising and lowering the window glass 3. Furthermore, since the slider 11 is conspicuous, the appearance quality of the automobile door 2 is also degraded, and there is room for improvement.

<Means for Solving the Problems> As a means for solving the above problems, in the window glass lifting guide device for an automobile door according to the present invention, the fixing part and the guide part are formed in a cross-sectional shape. A slider is provided at an end of the window glass and extends along the up and down direction of the window glass, and a guide portion of the slider is formed to be offset inward in the vehicle width direction from the inner surface of the window glass over its entire length, The guide portion of the slider is slidably guided by the groove of the upper sash of the automobile door, and the edge of the window glass is slidably guided by the groove of the lower sash that is offset outward in the vehicle width direction from the groove of the upper sash. The gist is to do so.

<Function> In other words, the edge of the window glass is slidably guided by the groove of the lower sash which is offset outward in the vehicle width direction from the groove of the upper sash, so that the edge of the window glass is prevented from falling through the window glass. The water is guided by the lower sash and flows to the lower end of the door panel without dripping onto the door lock and thus causing no adverse effects on the door lock. In addition, since the window glass is guided by the groove of the lower sash, the load on the slider is reduced accordingly, and the slider can be made smaller in proportion to this reduction, improving the operability of raising and lowering the window glass and the appearance quality of the automobile door. You will be able to improve your performance.

<Example> Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 7. In the following description, parts that are common or similar to the prior art and parts that are common to each embodiment are indicated by the same reference numerals, and redundant description will be omitted.

In this car door window glass lifting guide device,
A slider 32 formed with a fixed part 30 and a guide part 31 in a curved cross section is attached to the front and rear ends 17. of the window glass 3.
18 and extends along the up-and-down direction of the window glass 3 (up and down direction in the figure), and the guide part 31 is located inside the vehicle width direction (direction of arrow A) with respect to the inner surface 10 of the window glass 3 over its entire length. The groove 8 of the upper sash 6 of the automobile door 2 allows the glass run 12 to be formed in an offset state.
The guide portion 31 is slidably guided through the lower sash 7, and the lower sash 7 is offset outwardly in the vehicle width direction from the groove 9 of the upper sash 6, and the groove 9 of the lower sash 7 allows the window glass to be guided through the glass run 12. 3 is slidably guided. Furthermore, by guiding the window glass 3 through the groove 9 of the lower sash 7 when it descends into the door panel 19, the load is reduced and the required support strength is reduced, so that the rear end 18 Guide part 3 of slider 32
1 is shortened to approximately the size of the rear end portion 18 of the window glass 3.

Therefore, in this automobile door window glass lifting guide device, the water 24 that has fallen through the window glass 3 is guided by the groove 9 of the lower sash 7, flows to the lower end of the door panel 19, and hangs on the door lock 22. There will be no negative impact on this. Further, since the window glass 3 is guided by the groove 9 of the lower sash 7, the load on the slider 32 is reduced accordingly, and the guide portion 31 of the slider 32 is shortened in accordance with this reduction, and as a result, the window glass 3 The operability of lifting and lowering the door 2 and the appearance quality of the automobile door 2 are improved.

FIG. 7 shows another embodiment.

In this embodiment, unlike the previous embodiment in which only the guide portion 3 was shortened, the entire slider 40 at the rear end portion 18 is approximately 1/1/2 the size of the rear end portion 18 of the window glass 3.
It is distinctive in that it is reasonably short. Therefore, the appearance quality of the automobile door 2 and the operability of raising and lowering the window glass 3 are further improved.

Note that this invention is mainly intended for the side where the lower sash 7 is provided, that is, the wide end side of the window glass 3, so detailed illustrations and explanations are omitted for the opposite end side. Omitted.

Further, in each of the above embodiments, explanation has been given only for the case where the rear end portion 18 of the window glass 3 is wide, but the same applies to the opposite case, that is, when the front end portion 17 is wide. Of course, that is true.

<Effects of the Invention> As described above, the window glass lifting guide device for an automobile door according to the present invention raises and lowers the edge of the window glass using the groove of the lower sash offset outward in the vehicle width direction with respect to the groove of the upper sash. Because the guide is slidable, water that has fallen down the window glass is guided by the lower sash and flows to the bottom edge of the door panel, without hanging over the door lock, thus preventing the water from reaching the door lock. It has the excellent effect of preventing adverse effects, and since the window glass is guided by the groove of the lower sash, the load on the slider can be reduced, and this reduction allows the slider to be made smaller, making it easier to raise and lower the window glass. It also has the excellent effect of improving the quality and appearance of the vehicle door.
