Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dam rubber of an adhesive window panel for a vehicle, and in particular, a predetermined adhesive thickness can be secured, and the thickness is constant regardless of the location of the window panel. The present invention relates to a dam rubber for an adhesive window panel for a vehicle.

[Prior Art] Generally, a vehicle window, for example, a vehicle 1 as shown in FIG.
There is a structure for attaching the window panel 3 to the front window 2 by fixing the window panel 3 to the vehicle body 1 by using an adhesive. As shown in FIG. 6, a dam rubber 5 is attached to the inner surface of the window panel 3 to prevent the adhesive 4 from overflowing, and the adhesive 4 is attached to the flange 6 formed on the edge of the window opening of the vehicle body 1. Place it
The window panel 3 is attached from the outside. When the window panel 3 is attached using the adhesive 4 as described above, the window panel 3 is pushed further in the state of being in contact with the adhesive 4 so that the window panel 3 is sufficiently adhered to the adhesive 4. I try to secure the sex.

Here, the dam rubber 5 used for the adhesive fixing of the window panel 3 is as follows.

As shown in FIGS. 6 and 7, the dam rubber 5 is formed by molding sponge rubber into a rectangular cross section, and is compressed when the window panel 3 is pressed to reduce its thickness.

Further, as another type, as shown in FIG. 8, a base 8 for attaching the dam rubber 7 to the window panel 3,
There is one formed by a lip portion 9 rising from the base portion 8 and formed by extruding synthetic rubber. When the window panel 3 is pushed, the lip portion 9 comes into contact with the flange portion 6 and bends to prevent the adhesive 4 from overflowing.

By the way, when adopting the above dam rubber,
When the pressing force at the time of attaching the window panel is too large, the dam rubber 5 of the first type is too compressed, and the dam rubber 7 of the second type is as shown in FIG. The lip portion 9 falls down, and it is not possible to secure a sufficient thickness to hold the window panel 3 in the event of a collision. Further, when the window panel 3 is pressed in a non-uniform manner, the thickness of the adhesive 4 becomes non-uniform.

For this reason, as shown in FIGS. 10 and 11, there is a dam rubber 10 in which a notch is provided at a predetermined position and a solid rubber having a predetermined thickness is attached as a spacer 11 (Japanese Patent Laid-Open No. 59-153615). See the bulletin).

[Problems to be solved by the invention]

By the way, in the window panel 3 attached using the conventional dam rubber 10 and the spacer 11 as described above, the thickness of the adhesive can be secured and a uniform adhesive layer can be obtained. When the vehicle body or the like is twisted, the force applied to the peripheral edge of the window panel 3 is different due to the difference in hardness between the dam rubber 10 and the spacer 11, and the window panel 3 may be damaged.

[Means for solving problems]

In the present invention, a means for solving the above-mentioned problems is a dam rubber for a vehicle adhesive window panel that is attached to the inner surface of the window panel to prevent the adhesive from overflowing, and a soft portion and this soft rubber are provided over the entire length of the dam rubber. That is, it is configured as the same cross-sectional structure including a hard portion having a width smaller than that of the portion.

〔Example〕

An embodiment of a dam rubber for an adhesive window panel for a vehicle according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of a dam rubber for an adhesive window panel for a vehicle according to the present invention.

In this embodiment, the dam rubber 20 has a soft portion 21 formed of a soft sponge rubber and having a substantially U-shaped cross section, and a soft portion 21 formed of hard solid rubber and having a substantially rectangular cross section provided inside the U-shaped portion of the soft portion 21. It is formed from the hard part 22 and is entirely formed on the string by double extrusion molding.

In the present embodiment, the cross section is the same in all parts over the entire length of the dam rubber 20. Further, in the present embodiment, the soft portion 21 is brought into contact with the window panel 3 to reduce the stress.

Therefore, according to the present embodiment, in order to attach the window panel 3 to the vehicle body 1, first one dam rubber 20 is attached to the third body.
As shown in the drawing, it is arranged so as to surround the peripheral edge of the window panel 3. At this time, since the hard portion 22 having a relatively high hardness is set to be fine, the corner portion 3a of the window panel 3 is set.
Also in, the dam rubber 20 can be easily bent. Then, the window panel 3 to which the dam rubber 20 is attached may be attached so as to be pressed against the flange portion 6 on which the adhesive 4 is arranged. When the window panel 3 is pressed, the soft portion 21 of the dam rubber 3 is crushed and the window panel 3 comes into sufficient contact with the adhesive. The thickness of the adhesive 4 is regulated by the dimension of and the uniform thickness of the adhesive 4 can be secured. Further, according to the present embodiment, since the structure of the cross section of the dam rubber 20 is the same at any position, it is caused by the partial difference in hardness of the dam rubber at the peripheral edge of the window panel 3 even when the vehicle body is twisted. The uneven force is not applied and the window panel 3 is not damaged.

In the above embodiment, the dam rubber 20 is composed of the U-shaped soft portion 21 and the rectangular hard portion 22. However, as shown in FIG. 25 and a soft member 26 surrounding the hard portion 25. As shown in FIG. 4, the dam rubber 27 has a cross section such that a rectangular soft portion 29 is placed on a rectangular hard member 28. It may have a substantially T-shaped structure.

[Effect of device]

As described above, the dam rubber of the vehicle adhesive window panel according to the present invention is configured to have the same cross-sectional structure including the soft portion and the hard portion having a width smaller than the soft portion over the entire length thereof. The distance between the window and the window panel is regulated by the size of the hard part of the dam rubber, and it is possible to secure a uniform and predetermined adhesive thickness.Because the cross-sectional structure of the dam rubber is the same at any position, the vehicle body is screwed. Even when the window panel is damaged, the window panel will not be damaged due to uneven and abnormal force caused by the partial difference in hardness of the dam rubber.
