A thin piece-shaped outer lip 23a is extended in the.

Below the head 23, an upper edge leg 24 and a side edge leg 25 are formed in a bifurcated shape having a common base end. The side edge leg 25 is located on the side opposite to the head 23 with respect to the upper edge leg 24, that is, on the outer lip 23a side, and the upper edge leg 25 is It has a substantially right-angled shape with respect to the portion 24. The upper edge leg portion 24 and the side edge leg portion 25 have the same cross-sectional shape, and the holding pieces 24a, 25a project toward the left side (the side of the window glass 2 when mounted on the vehicle body) at the tip thereof. The inner lips 24b and 25b each have a thin piece shape and extend rightward. Here, the length L1 from the base end of the upper edge leg 24 to the holding piece 24a and the length L2 from the base end of the side edge leg 25 to the holding piece 25a are both the thickness of the window glass 2 and The window glass 2 is set to be equal, and the window glass 2 can be fitted and held in any of them as described later.

In the window molding 21 of this embodiment, as shown in FIG. 3, in the section of the upper edge portion X of the material 22, the side edge leg portion 25 is completely cut off, and as shown in FIG. In the section of the side edge portion Y of the material 22, the holding piece 24a and the inner lip 24b of the upper edge leg portion 24 are cut off. Further, in the corner portion Z of the material 22, from the portion adjacent to the upper edge portion X to the portion adjacent to the side edge portion Y, the upper edge leg portion 24 is cut off as shown in FIGS. 4 to 5.

Next, a manufacturing procedure of the automobile window molding thus configured will be described. First, the material 22 of the wind molding 21 is extruded into the cross-sectional shape shown in FIG. Therefore, the leg portion 24 for the upper edge and the leg portion 25 for the side edge are formed in the material 22 along with the head portion 23 in the entire longitudinal direction. Next, as shown in FIG. 3, in the section of the upper edge X of the material 22, the side edge leg portion 25 is completely cut off, and further, as shown in FIG. 5, the section of the side edge Y of the material 22. 2, the holding piece 24a and the inner lip 24b of the upper edge leg portion 24 are cut off, and the upper edge leg portion 24 is cut off at the corner portion Z of the material 22 as shown in FIGS. 4 to 5. The manufacturing of the molding 21 is completed.

As described above, the wind molding 21 of this embodiment can be manufactured by two processes, that is, the extrusion molding process of the raw material 22 and the cutting process of unnecessary parts. Thus, there is no need to carry out the injection molding process of the connecting pieces 7 and 8 after the cutting process.

On the other hand, a mounting state of the automobile wind molding 21 thus configured on the vehicle body will be described.

FIG. 6 is a sectional view taken along the line AA of FIG. 2 showing an engaged state of the windshield for an automobile according to an embodiment of the present invention with respect to the upper edge of the window glass, and FIG. 7 is an embodiment of the present invention. FIG. 8 is a sectional view taken along the line BB of FIG. 2 showing the engaged state of the corner adjacent to the upper edge of the window glass of the windshield for automobiles as an example, and FIG. 8 shows the windshield for automobiles as one embodiment of the present invention. It is the CC sectional view taken on the line of FIG. 2 which shows the engagement state with respect to the side edge of window glass.

As shown in FIGS. 6 to 8, the window molding 21 is arranged in a gap between the upper edge and the left and right side edges of the window glass 2 and the window frame 26 of the vehicle body, and the window frame is bonded with the adhesive 27. The outer lip 23 a is bonded to the surface 26 of the window frame 26. Then, as shown in FIG. 6, in the section of the upper edge portion X, the upper edge leg portion 24 is inserted in the gap between the upper edge of the window glass 2 and the window frame 26, and the inner edge of the upper edge leg portion 24 is inserted. The lip 24b elastically contacts the inner periphery of the window frame 26, and the upper edge leg portion 24 is pressed by the upper edge of the window glass 2 toward the window frame 26 side to assume a substantially upright posture, and the upper edge portion 24 and the upper portion 23. The upper edge of the window glass 2 is held between the edge leg 24 and the holding piece 24a. Therefore, in the section of the upper edge portion X, the head portion 23 of the wind molding 21 serves to cover the gap between the window glass 2 and the window frame 26 and improve the appearance quality.

Further, as shown in FIG. 7, in the section of the corner portion Z, the side edge leg portion 25 is inserted into the gap between the corner of the window glass 2 and the window frame 26, and the side edge leg portion is inserted. 25 is pressed toward the window glass 2 side by an inner lip 25b elastically contacted with the inner periphery of the window frame 26 and is held in a substantially upright posture, and the holding piece 25a of the side edge leg portion 25 and the upper edge leg 25 are held. The corner of the window glass 2 is held between the base end of the portion 24. Therefore, the leg portion 24 for the upper edge is located between the window glass 2 and the head portion 23 of the wind molding 21 and acts in a direction of separating the head portion 23 from the window glass 2, but as described above, Since the portion 23 is elastically contacted with the window glass 2 in the section of the adjacent upper edge portion X, the corner portion Z is gradually separated from the adjacent portion with the upper edge portion X to the adjacent portion with the side edge portion Y. However, it guides the rainwater at the time of rainfall to the drain 28, and prevents the rainwater from flowing to the window glass on the driver's seat and the passenger's side, thereby improving the visibility.

Further, as shown in FIG. 8, in the section of the side edge portion Y, the leg portion for the side edge portion is provided in the gap between the left and right side edges of the window glass 2 and the window frame 26, almost like the corner portion Z. 25 is inserted, and the side edge leg portion 25 is pressed by the inner lip 25b and is held in a substantially upright posture, and the side edge leg portion 25 has a holding piece 25a and an upper edge leg portion 24. The side edges of the window glass 2 are held between them. Since this side edge portion Y is located at a position sufficiently separated from the section of the upper edge portion X where the head portion 23 elastically contacts the window glass 2, the head portion 23 is inevitably separated from the window glass 2. Then, a drain groove 28 is formed between the upper edge leg portion 24 and the upper edge leg portion 24. Therefore, in the section of the side edge portion Y, not only the head 23 of the wind molding 21 covers the gap between the window glass 2 and the window frame 26, but also the drain groove 28 guides the rainwater at the time of rain to operate. It prevents rainwater from flowing to the window glass on the passenger side and passenger side and improves the visibility.

As described above, the automobile window molding 21 of the above-described embodiment has the head 23 formed by extrusion molding to have the same cross-sectional shape in the longitudinal direction, and the head 23 formed by extrusion molding together with the head 23. At the upper edge portion X which forms an acute angle and corresponds to the upper edge of the window glass 2, the head is inserted into the gap between the upper edge of the window glass 2 and the window frame 26 by the holding piece 24a provided at the tip. The leg portion 2 for the upper edge which holds the upper edge of the window glass 2 with respect to the portion 23 and is cut off with a section of the side edge portion Y corresponding to the side edge of the window glass 2 leaving the base end. 4 and the head portion 23 and the upper edge leg portion 24 are extruded and provided on the opposite side of the head portion 23 with respect to the upper edge leg portion 24, and at the side edge portion Y, the window glass 2 Is inserted into the gap between the side edge of the window frame 26 and the window frame 26, and is held by the holding piece 25a provided at the tip. The side edge of the window glass 2 is held between the base edge of the upper edge leg 24 and the side edge leg 25 in which the section of the upper edge X is cut off.

Therefore, in the section of the side edge portion Y, the side edge of the window glass 2 is held between the base end of the upper edge leg portion 24 and the holding piece 25 a of the side edge leg portion 25, which is inevitable. A drainage groove 28 is formed between the head portion 23 and the upper edge leg portion 24, and thus the upper edge leg portion 24 and the side edge leg portion 25 of the extruded material 22 are appropriately cut off, The drain groove 28 can be formed only by properly using the legs 24 and 25 according to the part of the window glass 2. Therefore, the windmill 21 can be manufactured by performing only two processes, that is, the extrusion molding process of the material 22 and the unnecessary part cutting process, reducing the number of manufacturing processes and increasing the manufacturing cost. The width can be reduced.

By the way, the windmoles of the above-mentioned embodiments are composed of the material 22 extruded from polyvinyl chloride, but the present invention is not limited to this, and is flexible. As long as the upper edge leg 24 and the side edge leg 25 can be selectively inserted into the gap between the window glass 2 and the window frame 26.

Further, the upper edge leg portion and the side edge leg portion in the above-described embodiment are the upper edge leg portion 24 and the side edge portion having the same sectional shape, which are provided with the holding pieces 24a, 25a and the inner lips 24b, 25b. Although it is configured as the leg portion 25, the present invention is not limited to this. The gap between the upper edge of the window glass 2 and the window frame 26, or the left right side of the window glass 2 is not limited thereto. It may be inserted into the gap between the edge and the window frame 26 so as to be able to hold the upper edge and the side edges. Therefore, for example, the upper edge leg portion 24 and the side edge leg portion 25 may have different sectional shapes or the inner lips 24b and 25b may be omitted.

[0031]

[Effect of the device]

 As described above, the automobile window molding of the present invention is extruded together with the head portion formed by extrusion molding, and is held between the head portion by the holding piece at the tip of the window glass. An upper edge leg portion that retains the edge and is cut away with a section corresponding to the side edge of the window glass leaving at least the base end, and the upper edge leg portion that is extruded together with the head portion. The side edge of the window glass is held between the base edge of the leg for the upper edge and the side edge of the window glass by the holding piece at the tip, which corresponds to the upper edge of the window glass. Since all the sections have side edge legs that have been cut off, during windmill manufacturing, a material consisting of the head, upper edge legs, and side edge legs is integrally formed by extrusion molding. In the section corresponding to the upper edge of the windowpane, the side edge leg is cut off to hold the head and the upper edge leg. Hold the upper edge of the windowpane between them, and in the section corresponding to the side edge of the windowpane, cut off at least the base end of the upper edge leg to leave the base edge of the upper edge leg. Hold the side edge of the windowpane between the window and the holding piece of the side edge leg, so that the head is inevitably separated from the window glass, and the head and the upper edge leg are separated from each other. A drainage groove is formed between them, and in this way, it can be manufactured by two types of processes, the extrusion molding process of the material and the cutting process of unnecessary parts, reducing the number of manufacturing processes and reducing the manufacturing cost. It can be reduced significantly.
