Description

Description: BACKGROUND OF THE INVENTION (Industrial Application Field) The present invention relates to a window molding to be mounted on the periphery of a window glass of an automobile, and in particular, to form both sides and an upper portion of a window glass and a corner between them with one molded product. At the same time, on both sides of the window glass, listen to the window molding with rain gutter function.

2. Description of the Related Art In a front window of an automobile, a structure in which a window glass is directly bonded to a window opening of a vehicle body panel via an adhesive is often used. In this case, window glass is attached to the opening flange 141 of the vehicle body panel 140 which is bent and formed into an L-shape as shown in FIG.
Since the 150 peripheral edge is bonded by the adhesive 170, a gap 142 is generated between the glass edge and the vehicle body panel 140. Therefore, as shown in the figure, a molding 110 usually made of an extruded product of plastic is mounted in the gap 142 to cover the gap 142. Extruded products have the same cross section in the longitudinal direction as is well known, and those made of plastic are relatively easy to be bent,
It is suitable for decorating the periphery of the window glass described above.

In a mall of this type, a type provided with a gutter channel in recent years is used so that when a car travels in the rain, the rainwater that has been flushed to the side by the wiper is not transmitted to the window glass on the side of the vehicle body. However, the gutter channel is required only on the side of the window, and is not required on the upper part of the window connected to the roof of the vehicle body. Therefore, conventionally, two types of moldings, such as a molding with a rain gutter on the side of the window and a molding without a gutter on the upper side, have been prepared and used by being connected by a corner joint. However, the use of these three parts in combination is not only disadvantageous in terms of cost, but also requires a complicated assembling work, and furthermore, the appearance of the molding is different from the other parts in the corner coin coin part. In addition, such combined use entails the risk of their falling off or breaking.

In order to solve such a problem, Japanese Utility Model Application Laid-Open No. 63-20416 discloses a leg 130 as shown in FIG. 11 to FIG.
Extruded product 111 provided with two grooves 131 and 132 on the glass side
As shown in FIG. 12, in the mall central portion 110c attached to the upper part of the window glass 150,
The lower portion of the leg portion 130 is cut off by a predetermined length so that the lower groove 132 is removed, and the molding side portion 110a attached to the side portion of the window glass 150 has two strips as shown in FIG. The grooves 131 and 132 of the molding are left, and the upper groove 131 left without being cut off of the molding central portion 110c is attached to the window glass edge 153 at the top of the window, while the molding side portion 110a is It has been proposed that the upper groove 131 be a rain gutter by attaching the lower groove 132 to the window glass edge 151 at the side of the window.

However, in this configuration, when the molding is mounted and fixed, the groove for the window glass 150 is different between the molding center portion 110c and the molding both side portions 110c, so that the mounting position (height) with respect to the window glass is different, It has been found that the surface of the exterior part is forcibly deformed in a short region where the part 110c changes to the molding side part 110a, and that the surface is likely to be wavy or wrinkled. This is such that the periphery of the window glass 150 in the area changes so as to draw an arc with a predetermined curvature.In order to make the molding 110 follow the arc shape, the molding 110 is moved not only in the height direction but also in the longitudinal direction. It seems that there is one factor in attaching while bending. In this molding, the edge of the window glass is fitted and fixed in a groove provided on one side of the molding. However, the gap between the edge of the window glass and the body panel is inherently narrow, and is bonded to the body panel. It is difficult to attach such a mall to the periphery of the window glass after the window glass has been made. This may be a problem that can be solved by attaching the mall to the window glass prior to bonding the window glass to the body panel, but repair such as replacement of the mall is extremely difficult. A structure to be attached after the window glass is bonded is preferred. In addition, this molding has a problem that only a part of the exterior part is in contact with the vehicle body panel, and the mounting posture differs depending on the bonding position of the glass.

(Problems to be Solved by the Invention) The present invention aims to provide a window molding which has solved the problems of the prior art, and a first object of the present invention is to provide at least both sides of a window glass.

A second object of the present invention is to provide a window molding in which, when the molding is attached along the periphery of the window glass, the exterior surface of the molding does not have a waving or the like in a region from a central portion of the molding to both side portions of the molding. Things. A third object is to provide a window molding that can be mounted after the window glass is adhered to the vehicle body panel and that can be easily mounted. Other objects will be apparent from the description of the embodiment which will be described later.

As shown in FIGS. 1b and 1c, which are cross-sectional views of the extruded product cut along the line C--C,
In the upper surface of the glass pressing piece 22 constituting the one wall portion 21a facing the rain gutter groove 21, in other words, from the II line connecting the predetermined position of the inner wall 24 of the rain gutter groove 21 and the upper surface of the fin strip 23. By cutting off the gutter groove 21 so as to delete the upper central outer portion 27, a molding central portion 10c having a central outer surface 63 extending from the glass presser piece 22 to the fin strip 23 is formed. .

Also, as shown in the figure, first, as shown in the figure, the molding corner portion 10b which changes from the molding central portion 10c to the molding side portion 10a is formed by extrusion molding 1 to form the molding central portion 10c.
From the end II of the II line (the end of the molding center portion 10c on the molding corner portion 10b side) from which the exterior portion 27 of the center portion 1 is cut off, the upper wall 25 of the rain gutter groove 21 of the molding side portion 10a ( (Corresponding to the lower surface of the wall portion 21b) and cut obliquely a predetermined length so as to cross the rain gutter groove 21 toward the first cut surface 61. A line II-III reaching a predetermined position IV on the surface 28 of the exterior unit 20 so as to form a second cut surface 62 that opens from the position III toward the molding central portion 10c and opens the mouth with respect to the first cut surface 61. The central side exterior portion 27 'defined by -IV is cut out in a V-notch shape, and the first cut surface 61 is formed as an oblique surface. That is, a part of the exterior part 27 ′ is cut off so as to make the V-shaped cut 26 of the exterior part 20 in the area 13 changing from the molding central part 10 c to the molding side part 10 a, thereby forming an oblique first cut surface 61. At this time, the cut-out exterior portion 27 in the center portion 10c of the molding and the exterior portion 27 'of the corner portion of the molding can be cut off together. In the width direction of the extruded product 11 (mall 10), cut lines II'-II 'and II in FIG.
As indicated by I'-III ', the molding is cut in the substantially same direction as the cutting line II of the center portion 10c. Next, the extruded product 11 cut in this way is cut along the cutting line III-I.

By pressing down and deforming to the first cutting surface 61 formed by the cutting line II-III, the first cutting surface 61 and the second cutting surface 62 are brought into close contact with each other, and the joint portion is joined by bonding or welding. Thereby, the molding corner portion 10b is formed. Thereby, the sloped surface 20 of the exterior part connecting the central exterior part surface 63 of the molding central part 10c and the exterior part 20 surface 20a of the molding side part 10a is formed, and a rain gutter channel is formed on the molding side part 10a. Rain gutter 21
The opposing wall portions 21a and 21b gradually approach from the molding side portion 10a to the molding central portion 10c side, and join before reaching the molding central portion 10c to close the rain gutter groove 21. Accordingly, the rain gutter groove 21 does not open at the upper end of the window glass to the exterior surface of the upper surface of the molding, and the
It is formed so as to converge as shown in the figure.

The joining in this case is performed by adhesion or welding.
In the case of bonding, an adhesive such as dope cement in which the plastic forming the extruded product is dissolved in a solvent or a good solvent of the plastic forming the extruded product is applied to the first cut surface 61 or the second cut surface 62 and joined. It is desirable to do. When the extruded product is made of a soft vinyl chloride resin, usable solvents include tetrahydrofuran and cyclohexanone. On the other hand, in order to join the first cut surface 61 and the second cut surface 62 by welding, as shown in FIG. 7 and FIG. The central part and the joint part of the extruded article 11, that is, the center part 10 c and the corner part 10 b of the molding are sandwiched between dies 81 and 82 such as silicone resin having a predetermined cavity shape, and electrodes 83 provided on the upper and lower surfaces of the mold. , 84, that is, the extruded product itself is heated and melted by dielectric heating, and the joint portion 64 (the first cut surface 61 and the second cut surface 62) is welded and extruded. It is preferable to eliminate traces of resection appearing on the product surface. At this time rain gutter 21
The central exterior surface 63 of the molding central portion 10c cut away is sandwiched between the molds 81 and 82 together with the joining portion 64, and the joining portion 64 is welded and the central exterior surface 63 of the molding central portion 10c is melted. And a smoother surface. In the figure, reference numeral 85 denotes a high-frequency oscillator.

In the molding 10 pressurized in this manner, the molding central portion 10c has no rain gutter groove, and the molding side portions 10a on both sides in the longitudinal direction of the molding have glass holding pieces 22.
Subsequently, a rain gutter groove 21 is provided. The molding corner portion 10b, which changes from the molding central portion 10c to the molding side portion 10a, is formed by the above-described processing.
The surface of the exterior part of the molding and the center part 10c of the molding are continuously connected by a smooth inclined surface 20b, and the leg part 30 is common to the molding side part 10a and the molding center part 10c. At this time, as is clear from the above,
Since the lower part of the exterior part 20 including the fin strips 22 and the fin strips 23 and the leg parts 30 are not subjected to any processing,
The positional relationship among the glass pressing piece 22, the fin strip 23, and the leg 30 over the entire length of 10 is the same as that of the extruded product.

Therefore, common leg portions 30 are provided on the upper portion 53 of the window glass 50 to cover the molding central portion 10c, and the side portions 51 of the window glass 50 are covered with the molding side portion 10a. 6, the glass pressing piece 22 is mounted so as to be placed on the periphery of the window glass 50 over its entire length as shown in FIG. The exterior has no gutter groove at the upper part of the window glass, and has a gutter groove 21 formed at the side of the window glass. Moreover, at this time, the surface of the exterior portion of the molding corner portion 10b from the upper portion of the window glass to the side portion of the window glass is connected by a series of smooth inclined surfaces 20b.

When inserting the leg 30 into the gap 42, the glass side locking piece
32 is formed obliquely from the tip of the main leg 31 so that an end 34 having a step 35 on its outer surface is separated from the main leg 31 as described above.
Because they extend toward
33 is inserted in such a manner that the end portion of the glass plate 33 slides against the glass edge and the vehicle body panel, and when the outer surface stepped portion 35 of the glass side locking piece 32 is positioned below the glass, the elasticity of the vehicle body panel locking piece 33 causes the glass The locking piece 32 and the main leg 31 are pushed toward the glass 50, and the step 35 on the outer surface of the leading end is locked to the lower surface of the end 54 of the glass 50 so that the glass-side locking piece 32 sinks under the glass.
At this time, it goes without saying that the glass pressing piece 22 of the exterior part is placed so as to be in close contact with the peripheral upper surface of the glass 50, and the fin strip 23 on the vehicle body side is also in close contact with the vehicle body panel 40.
As a result, the gap 42 between the window glass 50 and the body panel 40 is
Is concealed in series at the top and on both sides.

It will be apparent that the present invention is not limited to the extruded products according to the above-described embodiment, but can be similarly applied to other extruded products 211 and 311 whose cross sections are shown in FIGS. 9 and 10.

2 to 4, reference numeral 39 denotes a reinforcing core material such as an aluminum foil or a polyester film embedded in the main leg 31 of the extruded product 11, which is embedded at the same time as the extruded product 11 is formed. Reference numeral 70 denotes an adhesive for bonding the window glass 50 to the vehicle body panel 40.

(Effect) As described above, the present invention is configured such that the molding covering the side portion and the upper portion of the window glass is constituted by one molding having a common mounting leg, so that the molding is formed around the periphery of the window glass. When mounted, the mounting position with respect to the glass and the vehicle body is constant at the side and upper portions of the window glass. In other words, since it is not necessary to deform the molding in the height direction, it is easy to attach the molding, and there is no possibility that a defect such as deformation occurs in the exterior part. Further, the mounting may be performed by inserting the molding legs into the gap between the window glass and the vehicle body panel after the window glass is bonded to the vehicle body panel, so that the mounting posture can be easily adjusted.

On the other hand, as a molding exterior part, while being composed of one extruded product, there is no rain gutter groove in the center part of the molding covering the upper part of the window glass, but it has rain gutter grooves on both sides of the molding covering the side part of the window glass. Therefore, rainwater pushed by the wiper is prevented from flowing to the side of the vehicle body. Also, the gutter grooves are formed so as to converge at the corners of the mall, and the appearance is beautiful.
