Description

[Detailed description of the invention] The present invention relates to a device for raising and lowering the window glass of a side window of an automobile, and in particular, its purpose is to enable the window glass having a sufficiently large area to be completely opened. be.

As shown in FIG. 1, a conventional car side window lifting device moves a window glass 1 through two parallel guide sashes 2 and 3.
Because it was configured to be raised and lowered in a straight line along the
If the lower part of the door 4 is narrow due to the influence of the wheel house etc., as in the case of the rear door 4 of a four-door car,
If the area of the window glass 1' is made large enough, the window glass 1' will end up hitting the door 4, which has the disadvantage that the window glass 1' cannot be opened completely. Was.

This invention solves the above-mentioned problems, and by changing the posture of the window glass and moving it up and down to avoid obstacles, it is possible to completely open a window glass that has a sufficiently large area. It is characterized by the following.

Furthermore, the present invention is characterized in that it can be applied not only to the side window provided on the rear door of a four-door vehicle, but also to the rear side window and front door side window of a two-door vehicle.

Embodiments of the present invention will be described below with reference to the drawings. Figure 2 shows a first embodiment in which the present invention is applied to a side window opened in the rear door of a four-door car.
1 is a rear door main body, and a cutout portion 10a is provided at the rear of the lower part of the main body 10 to allow the wheel house to escape.

11 is a side window.

The window 11 is provided with a window glass 12 having a sufficiently large area to cover the entire window 11, and the window glass 12 can be moved up and down by a lift drive arm 13 whose one end is pivotally attached below the window 11. is supported by.

A guide groove 14 is provided along the lower edge of the window glass 12, and a support roller 13a pivotally attached to the tip of the arm 13 is slidably fitted into the iron 14.

A pair of guide sashes 15 and 16 are provided on both sides of the elevating drive arm 13 to guide the side parts 12a and 12b of the window glass 12 so that the window glass 12 can move up and down while changing its attitude counterclockwise in the figure. It is being

That is, both the sashes 15 and 16 are appropriately bent to avoid the notch 10a so as to be able to hold both sides 12a and 12b of the rotating window glass 12.

A guide roller 18 (see FIG. 3) is pivotally attached to the lower edge of the window glass 12 via a holder 17, and the guide roller 18 is fitted between the two sashes 15 and 16 to move the window glass. 12
control rail 19 that guides the
is provided independently of the lift drive arm 13.

In the above configuration, when the lift drive arm 13 is rotated clockwise, the guide roller 18 is guided along the straight portion 19a of the control rail 19, and the window glass 12 approaches the notch 10a of the door body 10. (state A in the figure),
The guide roller 18 is guided by the bent portion 19b.

At this time, the window glass 12 is turned counterclockwise, and the side portion 12a of the window glass 12 reaches the lowest portion 10b below the notch 10a.

Therefore, the upper edge of the window glass 12 is completely hidden under the window 11.

The reason why the window glass 12 can freely change its attitude in this way is due to the structure in which the control rail 19 is provided independently of the lifting drive arm 13.

FIG. 4 shows a second embodiment of the present invention, and among the components in the figure, the same reference numerals as in FIG. 2 have the same structure and function as in the above embodiment. Detailed explanation of these will be omitted.

This embodiment is characterized in that the linear control rail 19 is installed with an arbitrary inclination. With this configuration, the window glass 12 can be lowered while changing its attitude at the same time as the lowering starts. As in the above embodiment, it can be displaced to the lowest part 10b below the notch 10a.

In this embodiment, since the control rail 19 is arranged on a straight line, it is easy to manufacture and can be provided at a lower cost.

FIG. 5 shows a third embodiment of the present invention, which is applied to a rear side window of a two-door car.

Among the components in the figure, those having the same reference numerals as in FIG. 2 have the same structure and function as in the first embodiment.

For such a window 11, as in the first embodiment, it is possible to make one side 12a of the window glass 12 reach the lowest part 20b below the notch 20a formed below the vehicle body 20. The upper edge of the window glass 12 can be completely hidden below the window 11.

FIG. 6 shows a fourth embodiment of the present invention, which is applied to a side window of a front door.

Among the components in the figure, those having the same reference numerals as in FIG. 2 have the same structure and function as in the first embodiment.

In the figure, 21 is a front door body;
A door lock device 22 is provided on the rear side of the vehicle.

Here, a pair of guide sashes 15 and 16 are provided on both sides of the elevating drive arm 13 to guide the side parts 12 a and 12 b of the window glass 12 so that the window glass 12 can move up and down while changing its attitude clockwise in the figure. A roller 1, which is directly pivoted to the window glass 12, is provided between the two sashes 15 and 16.
A control rail 19 is provided which fits into the window glass 8 and guides the window glass 12 in the clockwise direction in the figure.

Therefore, when the lift drive arm 13 is rotated clockwise, a downward force is applied to the window glass 12 via the support roller 13a, and a downward force is applied to the window glass 12 via the guide roller 18.
A clockwise force acts on 2.

Therefore, the window glass 12 sequentially descends from state C to state D in the figure while changing its posture in the clockwise direction, and reaches the lowest portion 21 a below the door lock device 22 .

Therefore, the upper edge of the window glass 12 is hidden below the side window 10.

As explained above, the present invention provides a pair of guide sashes for guiding both sides of the window glass so that the window glass can move up and down while changing its posture in a specific direction, and a pair of guide sashes are provided on the window glass between the two sashes. Since a control rail is provided that fits into the guide roller and guides the window glass along both sashes, it changes the attitude of the window glass and avoids obstacles such as the wheel house and door lock device. It becomes possible to lower the window glass, and the window glass having a sufficient area can be completely hidden under the window.

Therefore, it becomes possible to improve the visibility and the feeling of openness when the window is opened.

Further, since the present invention changes the attitude of the window glass using the guide roller and the control rail, it is possible to completely open the window with a very small number of parts.

Therefore, manufacturing and assembling of parts is simplified, and supplies can be made at a very low cost.

Furthermore, in the present invention, the guide roller provided on the window glass is guided by a control rail provided independently of the arm that drives the window glass up and down, so that the window glass moves smoothly and the window glass is guided. It also has the effect of eliminating the need to incorporate it into the satush.
