Description

[Detailed Description of the Invention] The present invention relates to a connection structure for moldings in vehicles and the like.

Generally, a window frame 1 of a vehicle is made by rolling a metal strip having a certain width and thickness to form a window frame material 3 having grooves 2 having a substantially U-shaped cross section by rolling the bottom shape as shown in FIG. It is formed by joining the inclined ends of the window frame material 3 to each other.

Recently, the surface of the window frame 1 and the surface of the joint are covered with a cover 4 made of synthetic resin as a molding having a C-shaped cross section as shown in FIG.

The ends of the cover 4 are joined to each other so as to maintain the same external shape as the window frame 1. Conventionally, as shown in FIG. A metal mesh 5 is arranged on the back side of the double-strength bar 4, and is heated and pressed with a heater 6, thereby embedding this mesh in the cover 4 as shown in FIG. By doing so, they are joined, and in this joined state, they are attached to the window frame 1.

However, with this method, the mesh 5 is integrated with the cover 4 accurately positioned, which makes the joining work complicated, and when the two force bars are joined,
Since the cover 4 has to be transported to the installation location on the window frame 1, it is not easy to transport.Moreover, the gap between the joints of the cover 4 can be seen from the front side, which spoils the aesthetics.Furthermore, water can enter through the gap between the joints, damaging the window. This has drawbacks such as causing the frame 1 to rust.

In the present invention, the covers are joined by a synthetic resin connector that covers at least the surface of the facing portion of the cover, and will be described in detail below using examples.

5 to 7 are diagrams showing an embodiment of the molding connection structure according to the present invention. In the figures, a window frame cover 7 as a molding for a vehicle has a substantially C-shaped cross section and a surface It has a stepped portion 8 that follows the surface of the window frame,
The end of this cover 7 is a beveled end which is inserted into a clamping gap 10.11 formed in the connector 9.

In this case, the inclined end of one cover 7 may be bonded to the wall of the clamping gap 10 with adhesive 12, but according to the integral fixing method described later, the fixing force can be increased and the connector 9 can be attached to the double-strength bar 7.
a vertical piece 13 located in the gap between the inclined ends of the vertical piece 1;
3, and the upper and lower covering pieces 14 and holding pieces 15 form the clamping gap 10.11.

The covering piece 14 is formed to cover the entire surface of the double force bar 7, and can close the gap between the opposing parts of the double force bar 7.

The length of the holding piece 15 is set to be longer than that of the covering piece 14, so that by positioning the end of the cover 7 on the upper part of the holding piece 15 and sliding it, it can be inserted into the clamping gap 10.11. becomes easier.

As an example of installing the double force bar 7, first, attach one cover 7.
The inclined end is fixed to one of the clamping gaps 10 by means described later, and the connector 9 is integrated with the cover 7.

The cover 7 with the connector and the cover 7 without the connector are transported to a cover installation location, and the cover 7 with the connector is first attached to the front side of the window frame material 3, and then the other cover 7 is used to attach the cover 7 to the window frame material 3. Cover the frame material 3 and insert its inclined end into the clamping gap 11.

This allows the covering piece 9 to cover the opposing portion of the double-strength bar 7, preventing water from entering, suppressing rust, and maintaining the aesthetic appearance. The cover 7 and the cover 7 without a connector can be mass-produced, transported to a mounting location, and mounted on the window frame of a vehicle, making transportation and mounting easy.

Here, the method for integrating the connector 9 and the cover 7 in this embodiment is as follows.

That is, by inserting one end of one cover 7 into an injection mold for the connector 9 and injecting the same resin as the cover 7, the connector 9 as an injection molded product is welded to the end of the cover 7.

According to this, the fixing force can be increased and the process of connecting the connector 9 to one cover 7 can be omitted, thus making mass production possible.

As explained above, according to the present invention, a connector is provided that includes at least a covering piece that covers the surface of the facing portion of each molding, and this connector is integrated with one molding by gluing or welding, so that the molding It is easy to transport and manufacture before installation on a vehicle, and the installation work is also easy, and even after installation, there is no gap at the joint of the double force bar, so the aesthetics are not spoiled, and there is no water leakage. This prevents the infiltration of water and prevents rust from forming on the window frame.
