DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding for automobiles, and more particularly to a series of moldings mounted from a side edge of a windshield glass to a side edge of a roof.

[0002]

2. Description of the Related Art As shown in FIG. 10 and FIG. 11 showing an AA section thereof and FIG. 12 showing a BB section thereof, a molding for automobiles is provided between a side edge of a front windshield glass G1 and an outer pillar P1. There is a molding 50 in which a wind molding portion 50A attached to the gap S and a roof molding portion 50B attached to the groove M1 on the side edge of the roof R1 are formed in a series and the same shape by extrusion. There is also a molding that is installed up to the side edge of the rear windshield glass. The molding 50 in which the wind molding part 50A and the roof molding part 50B are integrally formed by this extrusion has advantages such as good appearance and simple molding work because there is no seam. In the drawing, reference numeral 51 denotes a metal core material, 52 and 53 denote clips for attaching a molding, and 54 and 55 denote adhesives.

However, in the above-mentioned series of moldings 50 having the same shape, the gap S1 at the side edge of the windshield glass and the shape of the groove M1 at the roof side edge are greatly different from each other. Different clips 52,5
3 is mounted on the vehicle body, and there are problems that two types of clips have to be prepared and that the mounting work is complicated. Moreover, the molding 50
Is formed by bending a band-shaped metal material having a width substantially equal to that of the molding 50 and forming claws 51a and 51b at both ends in the width direction so that the metal core material 51 can be securely engaged with the clips 52 and 53. Because of the structure buried inside, not only the product cost is high, but also the degree of freedom in bending is limited, and the boundary 57 between the windshield glass part and the roof part of the vehicle body cannot follow the curved shape, and the molding surface and In some cases, a gap was created between the vehicle bodies and the appearance was impaired.

Japanese Patent Application Laid-Open No. 5-46999 discloses that
As shown in FIG. 13, a molding 60 having a locking leg 61 and an auxiliary leg 62 has been proposed. Reference numeral 63 is a metal core material.

However, since the molding 60 is used as shown in FIG. 14 by cutting off the auxiliary leg pieces 62 in the windshield glass portion, the cutting is troublesome. Further, as shown in FIG. 15, in the roof R2, the locking piece 64 of the locking leg 61 is locked to a locking ridge R3 provided upright in the groove M2 of the roof R2. At this time, since a gap 68 for a rainwater suction groove is formed between one side edge 60a of the molding 60 and the wall W2 of the groove M2 of the roof at that time, car washing or waxing is performed. There is a problem in that, when hanging, the hand is caught on one side edge 60a of the molding 68 of the gap 68, and the molding 60 is raised in the width direction, so that the molding 60 is easily detached from the roof. Further, since a gap 68 for a rainwater suction groove is formed between one side edge 60a of the molding and the groove M2 of the roof, an undercut shape in which the groove M2 of the roof is narrowed on the outside is provided. Has a problem that is difficult to deal with. In addition, since the locking projection R3 of the roof tends to vary in height and angle during molding, the molding 60 may not be locked properly.
When the automobile is running, there is also a problem that the wind noise and wind resistance increase due to the rainwater inducing gap 68.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and relates to a molding in which a wind molding portion and a roof molding portion are formed in a series by extrusion molding. There is no need to use clips when attaching to the side edges of the roof, and it is not necessary to cut off a part of the molding when installing, so it can be installed easily and securely, and moldings with low wind noise and wind resistance provide.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a wind molding portion attached to a gap between a side edge of a windshield glass and an outer pillar and a roof molding portion attached to a groove at a side edge of a roof are formed in series.

A molding 10 of the present invention shown in FIG.
Is a series of extrusion molding of a wind molding portion 10A inserted into a gap between a side edge of a windshield glass of an automobile and an outer pillar, and a roof molding portion 10B inserted into a groove at a side edge of a roof. During the extrusion, the shapes of the wind molding portion 10A and the roof molding portion 10B are different from each other. At the boundary 10C between the wind molding 10A and the roof molding 10B, the shape gradually changes. In the case of a molding (not shown) that is attached from the front windshield glass section to the rear window glass section via the roof section,
The wind molding 10A is formed in series at both ends of the roof molding portion 10B.

The molding 10 has a basic shape common to the whole, and a predetermined portion is further provided with respect to the basic shape to constitute a wind molding portion 10A and a roof molding portion 10B.

The basic shape of the molding 10 comprises a main body 11 and elastic fins 20, as shown in FIG. The main body 11 has a surface portion 12 formed at an upper end of the main leg portion 13,
Further, a protruding ridge 14 is provided at a lower portion of one side of the main leg portion 13 and is made of an extrudable soft resin. The main body 11 of this example is made of a soft vinyl chloride resin having a hardness of about 90 to 95 °, which is harder than the elastic fins 20 and the elastic fins 25 for the roof described later.

In the wind molding portion 10A, the front surface portion 12 has a gap S between the windshield glass G and the outer pillar P as shown in FIG.
On the other hand, in the roof molding portion 10B, as shown in FIG.
And is formed to protrude from both sides of the main leg 13. As described above, since the surface portion 12 covers the groove M of the roof and no gap is formed between the side end of the surface portion 12 and the wall W of the groove M, wind noise and wind resistance when the vehicle is running are reduced. Further, when the car is washed, the wind molding 10 does not come off due to the hand being caught on the side end of the wind molding section 10A located in the gap.

In this example, the eaves-like portions 12a and 12b of the surface portion 12 projecting to both sides of the main leg portion 13 are shown in FIG.
As shown in FIG. 6, the wind molding portion 10A has the outer pillar P side, and the roof molding portion 10B has the portion 12a facing the side end of the roof R in the roof molding portion 10B as shown in FIG.
It is made thinner than the opposite portion 12b so that the hardness becomes relatively low. With such a configuration, when the molding 10 is mounted on the vehicle body, the eaves-like portion 12 is formed in the gap S between the side edges of the windshield glass.
Due to the elastic deformation of a, the surface portion 12 is pressed against the opening side (outside) of the gap S to beautifully close the gap S, and in the groove M on the side edge of the roof portion R, the opening side (outside) of the groove M Surface part 12
Will be pressed tightly and closed beautifully.

The main leg portion 13 serves as a support for the surface portion 12 and other portions. The main leg portion 13 extends along the roof portion from the windshield glass portion to the roof portion.
0 is formed to be thicker than the surface portion 12 so as to have a predetermined shape retaining property even when 0 is attached. Also,
In this example, a metal core material 15 is buried in the main leg 13 along the longitudinal direction, whereby the shape retention of the main leg 13 is further enhanced. As the metal core member 15, either a core member 15a made of a wire or a flat plate-shaped core member 15b having a narrow width indicated by a broken line is suitable. By embedding the metal core material 15 in the main leg portion 13 and not providing it on the surface portion 12, and further by using a wire or a narrow flat metal core material 15, the molding 10 can be performed without bending. Can easily follow the shape of the roof portion from the windshield glass portion, and can be more securely attached to the vehicle body.

The ridge 14 is a side surface 13a facing the win shield glass side of the main leg 13 or the center of the roof.
The lower portion is formed so as to protrude in the lateral direction similarly to the eave-shaped portion 12b of the surface portion 12, and forms a glass fitting groove 16 with the eave-shaped portion 12b. As shown in FIG. 5, in the wind molding portion 10 </ b> A, the ridges 14 connect the side edges of the windshield glass G fitted in the glass fitting grooves 16 to the eaves-like portions 12 of the surface portion 12.
b, while the roof molding 10
In FIG. 4B, as shown in FIGS. 4 and 6, it is a portion for supporting a roof elastic fin 25 described later. Therefore, the protruding ridges 14 are thickened to have a required rigidity, and the eaves of the surface portion 12 are not hindered from being inserted into the gap S on the side edge of the windshield glass G or the groove M on the roof side edge. It is formed shorter than the shape portion 12b.

Further, in the main body 11 of this example, a concave rainwater guiding groove 17 is formed on the upper surface of the surface portion 12 so as to face the same side as the glass fitting groove 16 along the longitudinal direction. In this way, rainwater is efficiently guided at the time of driving a car or the like, so that rainwater does not splash on the side window glass side.

On the other hand, the elastic fin 20 abuts against the wall Wa of the outer pillar P in the gap S between the windshield glass portions in the wind molding portion 10A, as shown in FIG. As shown in FIG. 6, the groove M is in contact with a wall Wb on the roof center side to maintain the posture of the molding 10 and prevent the molding 10 from coming off. An eave-like portion 12a of the surface portion 12 is provided at a lower portion.
It is projected shorter than it is. The elastic fin 20 is made of a resin softer than the main body 11 so as to be able to elastically contact with the wall Wa of the outer pillar P and the wall Wb of the groove of the roof, and has a hardness of about 75 to 80 ° in this example. And is extruded integrally with the main body 11.

In addition to such a basic shape, in the wind molding portion 10A, as can be understood from FIG.
A tapered tip leg 23 having an inclined surface 23a on the side surface on the sixth side
Extends downward. The reason for providing the tip leg 23 in this way is as follows. That is, as shown in FIG. 5, in the windshield glass portion, when the molding is mounted, the inclined surface 23a of the tip leg 23 comes into contact with the edge of the glass G, so that the inclined surface 23a forms a guide, This is because not only can the molding be smoothly inserted, but also the glass G and the outer pillar P can be fixed by inserting and fixing the tip leg portion 23 to the adhesive 27 provided in the recess Pa of the outer pillar P.
In this example, the tip leg 23 has a substantially wedge-shaped cross section (triangular shape) in this example, but is not limited thereto and may have an appropriate cross-sectional shape such as a trapezoid. However, it is preferable that the side surface on the glass fitting groove 16 side is the inclined surface 23a as described above. The material of the tip leg 23 preferably has the same hardness as the main body 13, and in this example, is made of the same material as the main body 13.

On the other hand, the roof molding unit 10
In FIG. 4B, as can be understood from FIG. 4 showing the cross section, a roof elastic fin 25 is provided at the tip of the ridge 14 in the basic shape, instead of the tip leg 23 of the wind molding portion 10A. 12 extend in the same direction as the eave-shaped portion 12b. This elastic fin 25 for roof
6, elastically presses against the roof outer wall Wc in the groove M on the roof side edge, and opposes the wall Wa on the opposite side.
The elastic fins 20 press-contact the roof molding portion 10B correctly in the groove M on the roof side edge, and prevent the roof molding portion 10B from coming off. The material of the elastic fin 25 for the roof is preferably softer than the material of the main body 11, and in this example, the elastic fin 25 is made of a soft vinyl chloride resin having the same shape as the elastic fin 20 in the basic shape at about 75 to 80 °.

In the roof molding portion 10B, the tip leg 2 of the wind molding portion 10A is provided.
The reason for not providing 3 is as follows. That is, the groove M at the side edge of the roof is provided for concealing a joint of the vehicle body panel. As shown in FIG. 6, the vehicle body panels whose end portions are stepped by press molding (see FIG. 6). Rp, Rp). Therefore, a curved step must be formed at the end of the vehicle body panel Rp at a corner portion (position 57 in the automobile shown in FIG. 10) which forms a boundary with the windshield glass portion. In molding, it is not easy to beautifully form a deep curved step at the end of a metal plate.
Therefore, usually, a groove shallower than the gap S of the windshield glass portion is formed in the corner portion, and a groove M on the roof side edge is formed in accordance with the shallow groove. Therefore, if the roof molding portion 10B is provided with a tip leg 23 similar to the wind molding portion 10A, the tip leg 23 collides with the bottom surface of the groove M on the side edge of the roof, and the roof molding portion 10B is correctly positioned in the groove. In such a case, there is a problem that the device is not easily attached and the device is easily detached. To avoid such a problem, a tip leg is not provided.

The roof molding section 1 of this example
The groove M on the roof side edge of the vehicle body on which 0B is mounted has an undercut shape in which the width on the opening side (outside) of the groove is narrow. For this reason, when a force is applied to the roof molding portion 10B to pull it out of the groove M, the elastic fins 20 and the roof elastic fins 25 of the roof molding portion 10B strongly press against the standing walls on both sides of the groove. Thus, the roof molding portion 10B is securely prevented from coming off. The groove M on the roof side edge of the vehicle body has steps Da, Db formed on both outer surfaces thereof, and the steps Da, Db
The eave-shaped portions 12a and 12b of the surface portion 12 are adapted to enter the space. Therefore, the positioning of the surface portion 12 is reliably performed by the step portions Da and Db, and meandering of the roof molding portion 10B is prevented.

The molding 10 for an automobile having the above-described structure is provided with a plurality of shields at the die portion of the extruder, and the openings (resin outlet) of the dies are partially opened and closed by the shields so that the window can be easily formed. The molding 10A and the roof molding 10B can be continuously extruded.

For example, as shown in FIGS. 7 to 9, the die 30 of the extruder is provided with a molding opening (resin outlet) 31 for forming the basic shape, the tip leg and the elastic fin for the roof. At the same time, a slide shield 41 for opening and closing the tip leg forming opening 32 and a slide shield 42 for opening and closing the roof elastic fin piece opening 33 are provided. Then, at the time of extrusion molding of the wind molding portion, as shown in FIG. 7, the slide shield 41 of the distal leg portion is retracted to open the distal leg portion forming opening portion 33.
While the sliding shield 4 of the elastic fin for the roof is opened.
2 to advance the roof elastic fin piece forming opening 33
Extrude the resin with the closed. At this time, the main body 11 and the tip leg 23 of the basic shape and the elastic fin 2
The part 0 is extruded integrally with a different material as described above. Then, the wind molding part 10A
Is obtained.

When the desired length of the wind molding portion 10A is formed, the slide shield 41 of the distal leg is advanced to close the distal leg forming opening 32, as shown in FIGS. 8 and 9. The sliding shield 42 of the roof elastic fin is retracted to open the roof elastic fin forming opening 33, and the extrusion is continued. At this time, the roof elastic fin 25 is formed of a resin softer than the main body 11. If it does so, the roof molding part 10B will be formed continuously after the said wind molding part 10A via the gradually changing part of a shape. The gradual change part of the shape is a wind molding part 10.
A and the boundary between the roof molding portion 10B.

In the case of molding which is mounted from the front windshield glass portion to the rear windshield glass portion via the roof portion, the slide of the tip leg portion is performed again when the required length of the roof molding portion 10B is formed. While retracting the shield 41,
The slide shield 42 of the elastic fin for the roof may be advanced to the state shown in FIG. 7, and the wind molding may be continuously formed again after the roof molding.

The molding 10 thus formed is extremely convenient because it is not necessary to cut off a part of the molding in a later step to form a wind molding portion and a roof molding portion.

[0027]

As shown and described above, in the molding for automobiles of the present invention, the wind molding and the roof molding are changed in shape and continuously formed integrally, so that post-processing is performed. It is not necessary to cut off a part of the molding, and it can be installed from the front windshield glass part to the roof part, and if necessary, the rear windshield glass part. Therefore, there is an effect that the forming operation and the mounting operation are facilitated and the cost is reduced. Also, since it can be attached to the vehicle body without using a clip, the mountability to the vehicle body is extremely good,
Cost reduction can be realized by omitting clips. In addition, between the roof groove and one side of the molding surface,
Since the gap for rainwater infusion described in the prior art is not formed, there is no possibility that the molding may be easily dislodged due to a hand being caught on one side edge of the molding during the car washing or the like. This can prevent wind noise and wind resistance increase.

Further, in the automobile molding according to the present invention, the width of the molding can be reduced according to the groove width of the roof. In addition, if the roof groove is undercut, the elastic fin and roof elastic fin will elastically deform when inserted into the groove, allowing the molding to be inserted into the groove. Since the piece and the elastic fins for the roof are pressed against the two walls of the groove to securely fix the molding, not only mounting is easy but also detachment is prevented.
Furthermore, if a metal core material is provided on the main leg, the shape retention of the molding can be improved without impairing the ability to follow the molding from the side edge of the windshield glass to the side edge of the roof. The properties and the appearance after wearing are improved. Further, if the rainwater guide groove is protrudingly provided on the upper surface of the surface portion, rainwater flowing from the roof and the windshield glass can be efficiently guided and drained.
