Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weather strip for fixing a wind panel of an automobile.

FIG. 2 shows an example of a conventional structure in which the wind panel 1 of an automobile shown in FIG. 1 is attached to the edge of an opening on the vehicle body side. That is, a glass fitting groove 5 is provided on the other side of the weather strip 4, which has a fitting groove into which a flange 3 extending from the roof panel 2 is fitted, and the wind panel 1 is fitted and fixed therein. Note that 6 indicates a molding member attached to the surface of the weather strip 4.

However, in the structure example shown in Fig. 2,
A step corresponding to the distance 1 is generated between the window panel 1 and the roof panel 2 or the molding member 6, and there is a problem that the outer shape is not flat. That is, since a streamlined and flattened line from the roof panel 2 to the wind panel 1 is desirable from the standpoint of design and wind pressure reduction during driving, it is ideal to eliminate the step l. However, since the weather strip 4 must have the function of reliably holding the flange 3 and the wind panel 1 and preventing the intrusion of rainwater, etc., it is necessary to have an appropriate wall thickness, and the above-mentioned flattened weather strip 4 must have a function of preventing rainwater from entering. If the wall thickness is reduced based on the requirement to obtain a tight line, the holding and sealing forces will be insufficient. Therefore, it is difficult to obtain the flattened line while maintaining the holding power and sealing power of the weather strip, and involves technical requirements that are mutually exclusive. Furthermore, since the weather strip 4 is a rubber product, there is also the drawback that the color cannot be unified.

The structure shown in FIG. 3 has been implemented as a means of dealing with the above problem. That is, the wind panel 1 and the roof panel 2 are bonded with an adhesive 7 interposed between them,
A dam rubber 8 is installed to prevent the adhesive 7 from protruding to the inside of the vehicle, and the wind panel 1 is
A molding member 9 is inserted and fixed so as to cover the gap between the roof panel 2 and the roof panel 2, so that an overall flat line can be obtained. However, in the case of such an adhesive type window fixing structure, the adhesion and dam rubber insertion processes are troublesome, and furthermore, when the molding member 9 is made of metal, it is necessary to insert a gasket between the vehicle body and the molding member to prevent rust. It is necessary to insert fasteners to prevent slippage on the side portions, which increases the cost, and also has the disadvantage that repair costs are high when the wind panel 1 is damaged.

The present invention has been made in view of the above, and includes:
The object of the present invention is to provide a weather strip for fixing a wind panel that eliminates the drawbacks of conventional structures. Still another object of the present invention is to obtain a flat panel mounting structure that is entirely level-free while maintaining a high mounting strength for a wind panel.

Embodiments of the present invention will be described below based on the drawings. That is, in FIG. 4, reference numeral 11 denotes a grooved welt with an inverted U-shaped cross section, which encloses a core material 12. A flange 14 extending from the body panel 13 is held in the groove of this grooved welt 11. Two pairs of flange retaining lips 15 are arranged opposite to each other so that the
a, 15b and 16a, 16b are formed. This grooved welt 11 and flange holding lips 15a, 15b, 16a, 16b are connected to the flange 1.
It forms the attachment part to 4. Furthermore, a soft material 17 extending from one side of the groove-shaped welt 11 and hard materials 18, 18 integrally provided on the outside of the vehicle, that is, on the left side in the drawing, provide a weather-resistant structure as a whole. A lip is formed. The soft material 17 is a soft elastic body such as rubber, and the hard material 1
8 and 18 can be made of hard rubber or the like and can be integrally extruded together with the soft material 17 during molding. The soft material 17 has seal lips 17a, 17.
b and 17c protrude and come into elastic contact with the wind panel 1 and the body panel 13 to improve sealing performance. A fitting and fixing groove 18a into which the wind panel 1 is inserted is formed in the hard material 18, and a fitting groove 19 having a substantially key-shaped cross section is bored between the hard materials 18 and 18 from the outside of the vehicle. The leg portion 20a of the molding member 20 to be mounted on the outside is inserted and locked. A protrusion 20b is provided at one end of the molding member 20, and the tip of the protrusion 20b is connected to the wind panel 1.
It has the function of coming into contact with the surface of the wind panel and pressing and locking the peripheral end surface of the window panel. A hook portion 20 c corresponding to the shape of the fitting groove 19 formed in the hard material 18 is formed at the tip of the leg portion 20 a of the molding member 20 . It is locked in a key-shaped part.

As described above, the wind panel fixing weather strip according to the present invention includes the soft material 17 extending from the attachment part side to the flange 14, and is integrally formed on the outside of the vehicle with the soft material 17. a soft material 18 having a wind panel fitting and fixing groove 18a, and a fitting groove 19 having a substantially key-shaped cross section from the outside of the vehicle in a portion of the hard material 18 facing the bottom surface of the wind panel fitting and fixing groove 18a.
A hook portion 20 is formed at the tip of the leg portion 20a of the molding member 20 to be attached to the outside.
c is engaged with the key-shaped portion of the fitting groove 19, and the peripheral end surface of the wind panel 1 is pressed by a protrusion 20b provided at one end of the molding member 20 on the outside of the vehicle. Therefore, there are various effects described below. That is, soft material 1
7 contributes to improving the sealing properties between the body panel 13 and the wind panel 1, and on the other hand, this soft material 17
Since the wind panel fitting and fixing groove 18a formed in the hard material 18 formed integrally with the wind panel 1 firmly holds the wind panel 1, even if the hard material 1
With a wall thickness of 8, there is no risk that the holding force will be insufficient even if it is formed thinly. Moreover, the peripheral end surface of the wind panel 1 is pressed from the outside of the vehicle by the protruding portion 20b provided at one end of the outside of the vehicle of the molding member 20 fixed to the fitting groove 19 bored in this hard material. Therefore, there is an advantage that the holding force of the window panel 1 is further improved by the pressing force of the protrusion 20b. Further, since the hook portion 20c formed at the tip of the molding member 20 is locked to the key-shaped portion of the fitting groove 19 formed in the hard material 18, the locking of the molding member 20 is ensured. It has the effect of becoming

Furthermore, a wind panel 1 and a molding member 2
This has a great effect of flattening the line connecting the body panel 13 and the body panel 13. In the enlarged example of FIG. 4, the molding member 20 is attached to the wind panel 1.
Although it appears to protrude slightly, the height difference between the wind panel 1 and the molding member 20 is 2.
Since it can be held down to about 1 mm, it is possible to virtually unify the top surface. Furthermore, by painting the surface of the molding member 20 or using resin or the like, there is an advantage that a total color matching the interior and exterior colors can be realized. Further, on the hard material of the portion of the wind panel 1 facing the bottom surface of the fitting and fixing groove 18a,
Since the fitting groove 19 is formed from the outside of the vehicle, when the wind panel 1 is fitted, the fitting fixing groove 18a tends to fall toward the fitting groove 19. In other words, the fitting fixing groove 18a Since the fitting and fixing groove 18a is tilted in the opening direction, the hard material 18
In spite of the fact that the wind panel 1 is formed as shown in FIG.

As explained above, the present invention provides a structure in which a streamlined and flattened line is obtained when fixing a wind panel to a vehicle body, which is effective in terms of design and wind pressure reduction. A feature of this invention is that the weather strip has sufficient holding power for the weather stripping member, and can be applied to various vehicles with great effect.
