Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window molding mounting structure and a manufacturing apparatus in which a window molding fitted in a gap between a window glass and a vehicle body panel is fixed by a fastener.

[0002]

2. Description of the Related Art Generally, a window molding is attached to a peripheral edge of a window glass attached to a window opening of a vehicle body panel. Specifically, a continuous elongated gap is formed between the peripheral edge of the window glass and the opening edge of the window opening of the vehicle body panel, and a window made of an elongated extruded member is formed in this gap. The molding is inserted and sealed. The window molding includes a leg portion that is inserted into the gap and a decorative portion that covers the gap from the outside of the vehicle.

When mounting such a wind molding, there are a case where the wind molding itself is fitted to the vehicle body panel side and a case where the wind molding is fitted to a fastener fixed to the vehicle body panel side.

As an example of fitting the window molding itself to the vehicle body panel side, US Pat.
There are 51432, 4165119 and 4441755. In this case, a part of the leg portion is fitted to the window glass side, and the elastic force of the leg portion causes the wind molding to be positioned at the central portion in the gap between the vehicle body panel and the window glass and the window of the vehicle body panel to be positioned. The window glass is arranged approximately in the center of the opening. As a similar example, Shoukai 60-158908
And window molding described in JP-A-62-178421.

On the other hand, as an example of attaching a window molding by using a fastener, see SAIkai 58-188.
No. 12, No. 61-115714, No. 62-1
0108, Japanese Utility Model Laid-Open No. 62-26719, Japanese Patent Laid-Open No. 61-
There is a wind molding described in No. 27723. The fasteners disclosed in these documents are provided with predetermined locking portions, and the legs of the window molding are fitted into the locking portions. If such a fastener is used, the wind molding can be securely attached to a predetermined depth, and as a result, the attachment depth of the window glass to the vehicle body panel can be accurately maintained. Incidentally, JP-A-59-164222
The window moldings described in Japanese Utility Model Publication No. 61-59421 and Japanese Utility Model Publication No. 61-59421 have substantially the same basic structure.

[0006]

When the fastener is used as described above, there is an advantage that the window molding can be accurately fixed and the position of the window glass in the depth direction can be accurately maintained, but on the other hand, The fitting portion on the side of the window glass is reduced, and the action force for restricting the position of the window glass toward the center of the window frame opening tends to be insufficient. Therefore, the attachment structure using the fastener has a problem that it lacks the function of arranging the window glass substantially at the center of the window opening of the vehicle body panel.

In view of this, the present invention is directed to mounting an automobile window molding in which the position of the window glass can be regulated in both the depth direction and the surface direction even when the window molding is mounted using a fastener. It is an object to provide a structure and a manufacturing method.

The part is configured to include a series of an outer peripheral arrangement part fitted and fixed to the fastener and an inner peripheral arranged part fitted to the peripheral edge of the window glass.

Further, in the method for manufacturing an automobile window molding according to the present invention, an extrusion forming port corresponding to a decorative portion of the window molding which covers a gap between the window glass and the vehicle body panel, and a window fitted in the gap. Using a die having an extrusion forming port corresponding to the leg portion of the molding, in a method for manufacturing an automobile window molding for extruding the window molding, an extrusion forming port corresponding to the leg portion of the die is formed. , For the extrusion forming port corresponding to the decorative part,
The extrusion is performed while moving the inner and outer circumferences of the window molding at a predetermined timing.

[0010]

In each of the means having such a structure, the leg portion forming a part in the longitudinal direction of the window molding is fitted to the engaging portion of the fastener provided on the vehicle body panel side, whereby the window glass is secured. Positionally regulated in the depth direction, the legs that make up the other part in the longitudinal direction of the window molding are fitted to the peripheral edge of the window glass, so that the window glass is positioned in the center direction of the window frame opening. It is becoming regulated.
