Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the structure of a molding portion of a weather strip tilt roof in which glass is fitted via an adhesive.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 to 3, as a molding portion structure 30 of a weather strip tilt roof in which a door glass 10 is fitted, a door is provided at one end of a base portion 31 against which the back surface of the door glass 10 is abutted. The U-shaped fitting portion 32 for fitting the end portion of the glass 10 is extended, and the U-shaped fitting portion 32 is provided.
When a lip 33 is projected on the bottom part of the base and a hollow seal part 34 is projected on the base part 31, when the door glass 10 is fitted,
An adhesive 50 is used between the base portion 31, the U-shaped fitting portion 32, and the door glass 10. In addition, in the portion corresponding to the hollow seal portion 34 of the base portion 31, there is formed a core-coring hole 35 into which the core is inserted at the time of molding and the core is extracted after molding.

However, if the hollow seal portion 34 is provided with the hollow core hole 35, as shown by a thin solid line in FIG. 3, the hollow core portion 35 is easily deformed and the sealing performance is deteriorated. Although a pad or the like is inserted into the portion 34 to prevent the deformation, there is a problem that the sealability is rather deteriorated and the man-hour for pad insertion is increased.

[0004]

The problem to be solved is that, in the conventional weather strip tilt roof mold forming structure, when the door glass 10 is fitted and adhered, the vicinity of the center hole 35 is deformed. However, in order to prevent the sealing performance from being deteriorated, it is necessary to insert a pad into the hollow seal portion 34, which increases the number of steps.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. 1 and 4 to 10. In the figure, one of the median lines from the apex angle of the isosceles triangle is filled, but the filled side represents the molding part, and the non-filled side represents the extrusion molding part. .

In the first invention, as shown in FIG. 5, a U-shaped fitting portion 32 for fitting the end portion of the door glass 10 is extended to one end of a base portion 31 against which the back surface of the door glass 10 is abutted. A lip 33 is projectingly provided on a bottom portion of the U-shaped fitting portion 32, and a hollow seal portion 34 is projectingly provided on the base portion 31, so that the base portion 31 and the U-shaped fitting are fitted when the door glass 10 is fitted. In the mold forming structure of the weather strip tilt roof in which the door glass 10 in which the adhesive 50 is interposed between the attachment part 32 and the door glass 10 is fitted, the part corresponding to the hollow seal part 34 of the base part 31 is provided. A center hole 35 is provided.

The second aspect of the present invention, as shown in FIG.
In addition to the configuration of the invention described above, a lip 37 capable of covering the center hole 35 is provided in a protruding manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment, 10 is a door glass, and 30 is a mold forming structure of a weather strip tilt roof to which the door glass 10 is fitted. One end of a base portion 31 against which the back surface of the door glass 10 is abutted. A U-shaped fitting portion 32 for fitting the end portion of the door glass 10 is extended to the bottom of the U-shaped fitting portion 32, and a lip 33 is projectingly provided on the bottom portion of the U-shaped fitting portion 32. 34 is provided so as to project, and the adhesive 50 is interposed between the door glass 10 and the base portion 31 and the U-shaped fitting portion 32 when the door glass 10 is fitted. In the present invention, especially the base part 3
A hollow core hole 35 is provided in a portion corresponding to the hollow seal portion 34 of 1. Further, it is preferable to project a lip 37 capable of covering the center hole 35. that time,
Due to the formation of the lip 37, as shown in FIG.
A lip molding gap 68 having an appropriate width is formed in a part of the mold split 65 between the core 61 and the mold 62 adjacent thereto.

To explain the operation, the door glass 10
Since the central core removal hole 35 is provided in the base portion 31 when fitting and adhering, the mold forming portion of the hollow seal portion 34 is not deformed to cause sealing failure, and it is not necessary to insert a pad. . Further, in the case where the adhesive 50 enters the hollow seal portion 34 through the hollow core hole 35 to affect the adhesiveness, it is possible to deal with this by attaching the masking tape 60 as shown in FIG. In order to avoid an increase in the attachment man-hour, as shown in FIG. 7 and FIG. 8, use a projecting lip 37 capable of covering the center core removal hole 35, tilt the lip 37, and then use It is also possible to cover the core hole 35 and prevent the adhesive 50 from leaking into the hollow seal portion 34. The present invention is not limited to a weather strip tilt roof, and is also effective when applied to a weather strip in which glass or a panel is attached via an adhesive.

[0010]

Since the present invention is constructed as described above,
By providing the center core removal hole 35 in the base portion 31 to secure the sealing property and to form the simple lip 37,
Prevents the adhesive 50 from leaking into the hollow seal portion 34,
The sealing property can be secured.
