Abstract

PURPOSE:To improve the sealing performance in a car glass mounting-holding body by fusing a hard resin holding part formed inside a mounting groove for mounting and holding a window glass integrally with a soft resin sealing part forming a tongue-shaped sealing piece outside. CONSTITUTION:A holding part 12 of U-shaped cross section having a mounting groove 11 for mounting and holding the peripheral edge of a window glass inside, is made of hard resin. On the other hand, a sealing part 14 having a tongue-shaped sealing piece outside is formed by soft resin. The holding part 12 is fused integrally with the sealing part 14 in a high frequency forming die to be joined to each other to form a window frame 10. By this constitution, the sealing performance can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flexible window frame for mounting and holding the window glass of a motor vehicle.

2. Description of the Related Art A fixed window glass 1 of an automobile A shown in FIG. 1 is fitted and held by a window glass attachment holder 2 made of a band-shaped resin and attached to the peripheral edge of a window opening.

The window glass attachment holder (hereinafter simply referred to as a window frame) 2 is, for example, at the corner portion indicated by the circular C portion in FIG. are connected by fitting and gluing them with a resin corner connecting piece 3, or by injection molding a corner connecting piece 3' between the ends of the straight window frames 2a and 2b as shown in FIG. They were joined and integrated either by or.

Problems to be Solved by the Invention However, in the former two conventional techniques, a stepped portion 4.4 is formed between the end face of the corner connecting piece 3 and the surface of the linear window frames 2a, 2b, and the window The overall appearance of the frame becomes uneven, spoiling its aesthetic appearance, and in the latter case, the end faces of the straight window frames 2a and 2b and the end face of the corner connecting piece 3' are joined and welded, so a step like the former occurs. However, the end surface joint 11A5.5 was exposed, which not only spoiled the appearance, but also had the disadvantage that the joint surface was likely to peel off.

In addition, conventional window frames were molded with either soft or hard resin, so while the tongue-shaped seal piece improves the sealing performance of soft resin, the strength to hold the window glass in place is weak, and hard resin Although the strength of fitting and holding the peripheral edge of the window glass is improved, it has disadvantages such as poor conformability to the shape of the sealing part and a decrease in sealing action.

Means for Solving the Problems The present invention provides a method for connecting the ends of a window frame in which the part for fitting and holding the window glass is made of hard resin and the window frame part having the tongue-shaped sealing piece is made of soft resin. This is a method of manufacturing a window frame in which the end faces of the window frame to be connected are brought into contact with each other, placed in a high frequency molding mold having a predetermined cavity, and heated under high frequency to fuse and join the abutting end faces to each other to integrate the window frame.

The window frame is constructed by molding the holding part that forms the fitting groove at the edge of the window glass from hard resin, molding the sealing part that forms the tongue-shaped seal piece from soft resin, and fuses and integrates the two. Therefore, the fitting groove firmly holds the window glass without deforming, the tongue-shaped seal piece adapts to the shape of the seal part and deforms and presses into contact, enhancing the sealing effect. Since they are integrally joined and connected by high frequency welding, the joined parts do not overlap, and since they are mutually fused, no joining line is generated.

Embodiment FIG. 2 is a sectional view of the window frame 10 of the present invention, and shows a fitting groove 1 for fitting and holding the peripheral edge of the window glass! A holding part 12 having a U-shaped cross section on the inside is molded from hard resin, and a tongue-shaped sealing piece 13 is formed.
The sealing part 14 existing on the outside is molded with a soft resin, and the hard resin holding part 12 and the soft resin sealing part 14 are respectively placed in a cavity in a high frequency mold as shown in FIG. The window frame 10 made of soft resin can be obtained by fusion-bonding and integrating the two by high-frequency heating.

Further, as shown in FIG. 3, when the end of one window frame 10a and the end of the other window frame lOb are joined together by a corner connecting piece 10c that connects the end of the other window frame lOb at a part of the corner, one window After the joint end surfaces of the frame 10a, the other window frame 10b, and the corner connection piece 10c are placed in contact with each other and inserted into the cavity in the high-frequency mold F, the respective contact end surfaces are fusion-bonded by high-frequency heating. Then, the window frames 10a, 10
b can be formed into a series of window frames 10 with corner portions via corner connecting pieces 10c.

Effects of the Invention In the present invention, since the holding part having the fitting groove for fitting and holding the peripheral edge of the window glass is made of hard resin, the fitting groove firmly holds the window glass without being deformed, so that the window glass does not fit into the window. There is no risk of it falling off from the frame, and since the seal part with the tongue-shaped seal piece is made of soft resin, the tongue-shaped seal piece adapts to the shape of the sealing area and deforms and presses against it. It is possible to reliably prevent foreign matter from entering the vehicle from the outside by sealing the part, and furthermore, since the hard holding part and the soft sealing part are fused and bonded using high-frequency heating, both can be sealed. There is no risk of the window frame peeling off, and in some corners of the window frame, the joint ends are fused together and integrated by high-frequency heating through the corner connection piece, so the joint ends will not separate. Moreover, since the end faces are joined by contact with each other, there is no risk of creating a step at the connection part, and the appearance of the window frame forms a uniform smooth surface with no irregularities, so there is no risk of spoiling the aesthetic appearance of the window frame, etc. , which has many excellent effects.
