Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding window device for an automobile.

An automobile slide comprising an opening formed in a vehicle body, a window frame attached to the opening, at least one slide glass fitted into a guide groove of the frame via a glass run, and slidably supporting the glass. The type window device has been well known (Japanese Utility Model Application No. 57-79012). Such a window device is widely used, for example, in a back panel at the rear of the cab of a freight vehicle or a door attached to the cab, or in a side part of a luggage compartment of a passenger-cargo vehicle.

In such window devices, there is also a device in which the distance between the upper and lower portions of the window frame is not constant, but is continuously changed, for the purpose of improving the appearance of the window or for reasons related to the structure of the vehicle body. It is publicly known. For example, the catalog "1980 Trucks by Toyota" (Toyota Motor
Sales USA Inc.), the lower part of the window frame attached to the back panel of the cab is placed approximately horizontally, while the upper part of the window frame is placed upward so that the central area protrudes slightly upward. Arrangements for curved sections are known.

However, when the window frame is formed in this way, when the slide glass slides in the narrow space between the upper and lower parts, a large resistance force acts on the glass slide, making it difficult to slide the glass smoothly. It becomes difficult.

This invention was made based on the above recognition,
The object thereof is to provide a sliding window device for a motor vehicle which can eliminate or reduce the above-mentioned conventional drawbacks by a simple construction.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a truck, with reference numeral 1 showing a cab, 2 a loading platform, and 3 a back panel constituting the rear wall of the cab 1.

The back panel 3 is provided with a sliding window device 4 according to the present invention, the details of which are as follows.

1 to 4, a substantially rectangular opening 5 is formed in the back panel 3, and a window frame 7 is attached via a weather strip 6 fixed to the inner peripheral edge of the opening 5. As shown in FIGS. The frame 7 extends along the inner peripheral edge of the opening 5, and is integrally constituted as a frame by an upper portion 7a, a lower portion 7b located below the upper portion 7a, and both side portions 7c. The upper part 7a extends above and opposite the lower part 7b. 3a is a roof rail fixed to the back panel 3.

Guide grooves are formed along the inner periphery of the window frame 7, and in this example, two rows of guide grooves 8 and 9 are formed over the entire inner periphery of the frame 7. Two fixed glasses 10 and 11 are fixed to one of the guide grooves, in this example, the guide groove 8 on the outside of the vehicle via a gasket 12. These fixed glasses 10 and 11 are located at both end areas of the opening 5, respectively, and a division bar 1 is fixed to the upper part 7a and the lower part 7b of the window frame 7.
2 and 13 hold the edges of both fixed glasses 10 and 11 facing each other, respectively. Reference numeral 13a in FIG. 2 is a brush provided on the division bar, and the brush 13a comes into sliding contact with a slide glass, which will be described later.

Another guide groove 9 formed in the frame 7
A glass run 14 is fitted over its entire circumference, and a suitable number of glass slides 15 and 16, two in this example, are fitted through the glass run 14. These slide glasses 15 and 16 slide in sliding contact with the glass run 14 while moving in the lateral direction
(Fig. 1), and can close both slide glasses 15 and 16 as shown in Fig. 1, close the space between the two division bars 12 and 13, or open it as shown in Fig. 3. I can do it. The glass run 14 is made of an elastic material such as rubber or soft synthetic resin. Furthermore, there is a slight drop between the bottom surface of the guide groove 9 and the portion of the glass run 14 that faces the bottom surface.
The back surface of the glass run 14 is curved so that a gap 30 (see FIG. 2) is formed.

By the way, the lower part 7b of the window frame 7
The entire frame extends horizontally while maintaining a substantially constant height, but the upper part 7a of the frame 7
As shown in an exaggerated manner in FIGS. 1 and 3, the central area A is gently curved and viewed in the lateral direction X of the vehicle.
is higher than that in both end regions B. In this way, the distance between the lower portion 7b and the upper portion 7a, which extend substantially horizontally, is not constant. Therefore, the distance D between the upper part 7a and the lower part 7b (FIGS. 2 and 4) is
The central area A is narrower than the central area A. For this reason, in the past, the slide glasses 15 and 16 were spaced apart by D.
when sliding it into the small end area B (third
(Figure), there was a drawback that the resistance force acting on the glass increased, making it difficult to slide the glass. Conversely, the slide glasses 15 and 16 are located in the end area B of the frame 7.
If the interval D is set so that the sliding movement is performed smoothly when the glass 15, 16 reaches
When sliding in the central area A, the gap D is too large, which inevitably causes the slide glasses 15 and 16 to wobble or the sealing between the slide glasses 15 and 16 and the glass run 14 to deteriorate.

Therefore, in the configuration according to the present invention, as shown in FIGS. 4 and 5, in the upper part 7a of the window frame 7, the distance D between the upper part 7a and the lower part 7b is the maximum. An appropriate number of slits 20 are formed at the bottom of the glass run portion located at a portion other than the portion where the frame is located, that is, the glass run portion fitted into both end regions B of the frame. This slit 20 penetrates from the side where the slide glasses 15 and 16 are located to the side of the gap 30 described above. Since the slit 20 is formed at the bottom of the glass run that slides into contact with the upper end surfaces of the slide glasses 15 and 16, the bottom can be elastically deformed in the direction of arrow C (FIG. 4) more easily than when there is no slit. can do. For this reason, slide glass 1
When sliding 5 and 16 in the end area B,
Since the glass run 14 pressed by the glasses 15 and 16 has the slit 20, the glass run 14 is pressed by the arrow C
It deforms easily in the direction, that is, without exhibiting a large resistance force. Therefore, the resistance force exerted on the slide glasses 15 and 16 by the glass run 14 is reduced compared to the case without the slit 20, and therefore the vertical distance D of the frame 7 in both end regions B is relatively narrow; Glasses 15, 16 operate smoothly. Conversely, when the slide glasses 15 and 16 slide in the central area A, the glass run 14 is difficult to deform because no slit is formed in the glass run portion existing in this area A. However, since the vertical distance D of the frame 7 in the central area A is relatively wide, the slide glasses 15 and 16
can operate smoothly. In this way, the slide glasses 15 and 16 operate smoothly both when they are located in the central region A of the window frame 7 and when they are located in both end regions B. In other words, it is possible to prevent rattling of the slide glasses 15, 16 or a reduction in sealing performance between the glass and the glass run without reducing the smoothness of operation of the slide glasses 15, 16.

In the above embodiment, a plurality of slits 20 are formed at the bottom of the glass run portions in both end regions B of the frame 7, but it is also possible to provide only one slit, or to extend the slits in the lateral direction X of the vehicle. Instead of extending in the direction of travel, it may be extended in any other suitable direction, for example in the direction of travel. Also slit 20
It suffices if they are formed on at least a portion of the bottom of the glass run located in both end regions B.

The present invention can also be applied to a sliding window device installed on the door of a car or on the side of the luggage compartment of a passenger/cargo vehicle (van).

As described above, according to the present invention, with the very simple structure of forming slits in the glass run,
Even if the distance between the upper part and the lower part of the window frame is not constant, the slide glass sliding therebetween can be operated more smoothly than before. Moreover, the original function of the glass run is not inhibited.
