Abstract

PURPOSE:To make pressing-in of a molding easy and make reliable the fitting of the molding over front glass, by a method wherein a length of a thick part of a body lip of the molding is varied according to a distance between a leg part of the molding and a body panel. CONSTITUTION:An upper molding M1a is fitted over an end fringe part of front glass G under a pinching and holding state by a decorative part 4 and pinching and holding lip 5 formed on a leg part 3. The tip part of a thin part 6b of a body lip 6 comes into contact elastically with a tilting part 1a of a body panel 1. Since a base end part of the body lip 6 is formed of a thick part 6a, the body lip 6 is fitted reliably over the end fringe part of the front glass G by reaction force. Then since an elastic contacting part is formed of the thin part 6b and bent appropriately, the upper molding M1a can be inserted smooth into a gap 2. Furthermore, although a body lip 6 of a side molding M1b is formed of only the thin part 6b, since its length is short, it does not bend greatly.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automobile having a structure in which the vehicle is fitted by being pushed into a gap created between the peripheral edge of the automobile windshield and the window frame of the body. The present invention relates to a windshield molding and a molding device thereof.

[Conventional technology]

In most modern automobiles, the shapes of the gaps formed between the top and side edges of the windshield and the body panel vary considerably. In other words, the angle of inclination of the body panel at the portion facing the end surface of the windshield is considerably different between the upper circumference and the side circumference of the windshield. Distances are different. In many automobile designs, the distance between the edge of the windshield and the body panel is longer at the top perimeter of the windshield than at the side perimeter.

In the case of a structure in which a molding is pushed between the windshield and the body panel after the windshield is installed, the body lip protruding from the leg of the molding comes into elastic contact with the body panel. The reaction force caused by the windshield causes the molding to fit into the periphery of the windshield. Therefore, if a molding with the same cross-sectional shape is attached to the entire circumference of the windshield, the distance between the end surface of the windshield and the body panel is longer at the upper periphery, so the body lip of the molding is attached to the body panel. The reaction force generated by elastic contact with the windshield is smaller at the upper periphery of the windshield.As a result, the molding may not be fitted in the correct position relative to the windshield, for example, the molding may be fitted at an angle, resulting in poor sealing performance, appearance, etc. There was a problem that caused damage to the If the thickness of the body lip is increased in order to increase the reaction force when the molding is installed and to ensure that the molding fits into the windshield, the reaction force of the body lip will be too large and the relationship between the windshield and the body panel will increase. The molding cannot be pushed smoothly into the gap.

Therefore, conventionally, the cross-sectional shapes of the moldings attached to the upper peripheral edge and the side peripheral edge of the windshield are different, two types of moldings are used, and these are connected using a corner joint. For this reason, there is a problem that the number of parts increases and additional man-hours are required to join these parts, leading to an increase in cost. In addition, it is difficult to precisely match the gloss, color tone, etc. of each molding and corner joint, resulting in poor appearance and
There was also the problem that over time, gaps were created at the joint surfaces between each molding and the corner joint, and the joints were damaged at this point.

[Problem to be solved by the invention]

The first problem of the present invention is to solve the problem by devising the cross-sectional shape of the body lip in a structure in which a molding is inserted between the windshield and the body panel.
The objective is to make it easy to push the molding and at the same time ensure that it fits into the windshield.

A second object of the present invention is that each molding attached to the upper periphery and the side periphery of the windshield is continuously molded and integrated into a single molding. By closing the gap that occurs between the body and the window frame, corner joints are no longer necessary, and the first object is also achieved.

[Means to solve the problem]

A first means adopted by the present invention to solve the above problems is to form the body lip of the upper molding attached to the upper peripheral edge of the windshield so that the thin part is continuous with the thick part joined to the leg part. In addition, the body lip of the side molding attached to the periphery of both sides of the windshield is made up of only a thin part, or a structure in which a thin part is continuous with a thick part joined to the leg part. The length of the thick part of the body lip was changed according to the distance between the molding leg and the body panel.

The second means is to form the body lips of the upper molding and the side molding to be thick, and to form bending grooves continuously in the length direction at predetermined positions along the width direction. , the distance between the base end of the body lip and the bending groove is changed depending on the distance between the leg of the molding and the body panel.

The third means is to install a shutter in the molding die to change the length of the thick part of the body lip protruding from the leg of the molding or the position of the bending groove provided in the body lip. By providing the molding in a linearly movable manner on the front surface, the upper molding and the side molding, which have different cross-sectional shapes, are continuously molded and integrated.

[Action of the invention]

In the case of a molding in which the body lip has a partially thickened part, the length of the thickened part of the body lip of the molding is longer at the upper periphery of the windshield where the distance between the body panel and the body panel is long. Because it is,
Even if the tip of the body lip comes into elastic contact with the body panel,
The body lip does not curve significantly, so the reaction force due to the impact increases, and the molding is securely fitted into the windshield. Since the part elastically contacts the body panel and curves, the leg part of the molding can be smoothly pushed into the gap between the windshield and the body panel.

In addition, in a molding in which the entire body lip is formed thick and a bending groove is formed at a predetermined position in the width direction, the body lip is largely bent at the bending groove, and the tip part is Since it makes elastic contact with the body panel, the body lip will not bend too much. Therefore, the reaction force due to the elastic contact of the body lip with the body panel increases, and the molding is reliably fitted into the windshield. In addition, when pressing the molding, the body lip is largely bent at the bending groove, so even if the entire body lip is thick, the molding can be smoothly inserted into the gap between the windshield and the body panel. Can be pushed.

Furthermore, the shape of the body lip changes depending on where it is installed, and if you use a molding with an integral structure in which two types of upper and side moldings with different cross-sectional shapes are continuously molded, it will not work like conventional molding. Eliminates the need to use corner fittings. As a result, the joint surface at the corner of the molding is eliminated, increasing its strength and improving the overall appearance of the molding. In addition, the number of molding parts is reduced to one, reducing the number of man-hours required for installation, leading to cost reductions. Also, when continuously forming moldings,
The body lip can be molded to match the shape of the gap between the end of the windshield and the body panel.
Mounting of the molding becomes easy and mistakes in mounting are eliminated.

〔Example〕

The present invention will be explained in more detail with reference to Examples below.

FIG. 1 is a perspective view of an automobile equipped with molding M1 of the present invention, FIG. 2 is an enlarged cross-sectional perspective view of the portion indicated by rcJ in FIG. FIG. 2 is an enlarged sectional view taken along the XX line, FIGS. 4 and 5 are enlarged sectional views taken along the X-X line and Y-Y line in FIG. It is a diagram.

In the molding MI according to the present invention, the upper molding M 1 a s and the side moldings M and b, which are respectively attached to the upper peripheral edge and both side peripheral edges of the windshield G, are continuously molded by a molding device described below and are integrally formed. It has become.

Upper molding M, a, and side molding M
, b include a leg 3 that is inserted into the gap 2 between the peripheral edge of the windshield G and the body panel 1 constituting the body window frame, and a leg 3 that is integrally molded on the upper end of the leg 3. and a decorative part 4 for closing the gap 2.

The leg portion 3 has a windshield G which cooperates with the decorative portion 4.
a clamping lip 5 for clamping the body panel 1;
body lift protrusions that come into elastic contact with the inclined portions 1a of the body lifters protrude in opposite directions, respectively. A decorative lip 7 that comes into elastic contact with the upper surface of the body panel 1 is provided on the decorative portion 4 so as to protrude in the same direction as the body lip 6.

As shown in FIGS. 2 to 5, the body lip 6 of the upper molding Mla has a thin portion 6b continuous with a thick portion 6a joined to the leg portion 3, while a side portion The body reinforcement of molding M+b is entirely formed of a thin wall portion 6b.

Further, as shown in FIGS. 4 and 5, the angle of inclination of the inclined portion 1a of the body panel 1 is larger at the upper edge of the body window frame than at the side edge. Therefore, the distance between the end surface of the windshield G and the inclined portion 1a of the body panel 1 is larger at the upper edge of the windshield G than at the side edge. Corresponding to this, the length of the body lip 6 of the upper molding M+a is longer than the length of the body lip 6 of the side molding M+b.
It is longer by the length of the thick portion 6a.

In order to attach this molding M to the gap 2 between the end surface of the windshield G and the inclined portion 1a of the body panel 1, first apply a sealant 8 to the body panel 1,
Insert the windshield G into the body window frame and fix the windshield G with the sealant 8. In this state, the upper molding M1a and the side molding M+b are continuously molded and integrated. When the molding M1 is pushed and inserted into the gap 2, the upper molding M+a part passes through the state shown in FIG. The upper molding Mla is fitted into the edge of the windshield G in a pinched state by the sandwiching lip 5, and the thin part 6 of the body lip 6
The tip portion of b comes into elastic contact with the inclined portion 1a of the body panel 1 (see FIG. 4).

The reaction force generated when the tip of the thin wall portion 6b of the body lip pro comes into elastic contact with the inclined portion 1a of the body panel 1 is caused by the thin wall as a whole because the base end of the body lip 6 is formed by the thick wall portion 6a. As a result, the upper molding M+a is reliably fitted into the edge of the windshield G by the reaction force. Further, as shown in FIG. 3, when inserting the upper molding Mla into the gap 2, the thin wall portion 6b of the body lip 6 comes into elastic contact with the inclined portion 1a of the body panel 1, but the elastic contact portion is not the thin wall portion. Since the body lip 6 is formed of thick-walled parts, the upper molding M is curved appropriately.
+a can be smoothly inserted into the gap 2.

In addition, since the length of the body lift pro is short in the side moldings M and b, the side moldings M and b can be smoothly inserted into the gap 2, and when completely inserted, As shown in Figure 5,
The tip portion of the body lift pro consisting of only the thin wall portion 6b comes into elastic contact with the inclined portion 1a of the body panel l, and the side moldings M and b are fitted into the edge portion of the windshield G by the reaction force. The body lip 6 of the side moldings M, b is formed only from the thin wall portion 6b, but since its length is short, even if the tip portion comes into elastic contact with the sloped portion 1a of the body panel 1, it will be largely curved. Therefore, the reaction force caused by the elastic contact of the body lip 6 is not reduced.

In addition, in FIGS. 2 to 5, 9 indicates a dam rubber for preventing the sealant 8 from being washed away, and 10 indicates a dam rubber.
A core material buried between the leg portion 3 and the decorative portion 4 of the molding M1 is shown.

Next, referring to FIG. 6, a forming apparatus for molding M1 will be described.

The molding die 11 is provided with an extrusion opening 12 corresponding to the cross-sectional shape of the upper molding M1a, and a shutter 13 is provided on the front surface of the molding die 11 so as to partially close this extrusion opening 12. It is being The shutter 13 is mounted so as to be linearly movable along the length direction of the opening 12a forming the body lip 6 in the extrusion opening 12. The rotation of the drive motor 14 is converted into linear motion by the conversion mechanism 15, so that the shutter 13 is guided by the shutter guide 16 and moves linearly. What is shown by a solid line in FIG. 6 is the molded state of the upper molding M+a, and what is shown by the two-dot chain line in the figure is the molded state of the side molding M+b.

And, as shown in the schematic diagrams of FIGS. 7 and 8,
From upper molding Mla to side molding M
+ To move to the molding of b (in the same figure, mark the transition part as A)
), when the shutter 13 is gradually linearly moved in the direction of arrow P during molding, the protruding length of the body lip 6 is gradually shortened, and at the same time, the length of the thick part 6a is also gradually shortened, resulting in a thick wall. As the portion 6a disappears, the body lip 6 is shifted to side moldings M and b formed only of the thin portion 6b.

Conversely, in order to transition from the side moldings M, b to the upper molding M+a (the transition part is indicated by B in the figure), the shutter 13 is moved linearly in the opposite direction to the above during molding, and the body At the same time as the protruding length of the lip protrusion gradually increases, the length of the thick part 6a formed at the joint with the leg part 3 gradually increases, so that the body lip 6 is divided into the thick part 6a and the thin part 6b. The process moves on to the molding of the upper molding M+a formed by the above.

By cutting the molding continuously formed in this way at a predetermined position and bending it at the connecting portion between the upper molding M+a and the side molding Mlb, the desired molding Ml is obtained.

Note that the body lip 6 formed on the side moldings M and b in the molding M1 of the above embodiment is formed only of the thin wall portion 6b, but the thick wall portion 6a is left in this portion as well. It is also possible.

Another molding M2 of the invention is shown in FIGS. 9-11.

This molding M2 consists of a leg part 3 and a decorative part 4 like the above-mentioned molding M1, and a body lip 6' is protruded from the leg part 3. At the same time, it is formed thickly over the entire width, and a bending groove 17 is continuously formed in the length direction of the body lip 6° at a predetermined position in the width direction. In the upper molding Mza to be installed, the bending groove 17 is formed near the tip of the body lip 6'', whereas in the side molding Mza to be installed on both sides of the body window frame! In b, a bending groove 17 is formed in a portion of the body lip 6'' close to the leg 3. That is, the body lip 6' is bent in accordance with the distance between the end surface of the windshield G and the body panel 1. The position of the bending groove 17 to be formed is determined.

Therefore, when inserting the molding M2 into the gap 2 between the windshield G and the body panel 1, the body lip 6° is bent greatly at the bending groove 17, as shown in FIG. Even if the entire body lift pro is formed to be thick, the molding M2 can be inserted into the gap 2 relatively smoothly.

When the molding M2 is completely inserted into the gap 2, the body lip 6' is largely bent at the bending groove 17 and comes into elastic contact with the inclined part 1a of the body panel 1. Body Lift Pro" is thickly formed over the entire width, so body lift Pro"
The reaction force caused by the elastic contact is considerably large, and as a result, the molding M is reliably fitted into the edge of the windshield G.

FIG. 12 shows a molding apparatus for the molding M2. An extrusion opening 12'' corresponding to the cross-sectional shape of the upper molding Mta is provided on the front surface of the molding die 11, and a shutter 13'' is provided on the front surface of the molding die 11. This shutter 13° is for forming a bending groove 17 at a predetermined position of the body lift projector, which is thick-walled as a whole and has the same width over the entire length. It moves linearly along the length direction of the opening 12'a that forms the "Body Linn Pro". In the same figure, the solid line and the dashed-double line are
These are the molding states of the upper molding Mta and the side molding Mzb, respectively.

[Effects of the Invention] (1) In the molding according to the present invention, the shape of the body lip changes in accordance with the shape of the gap between the peripheral edge of the windshield and the body window frame, so that it does not fit with the windshield. The legs of the molding can be smoothly pushed into the gap between the body window frame and the molding, and at the same time, the reaction force generated when the body lip comes into elastic contact with the body panel increases, so the molding can be securely inserted into the windshield. I can do it. As a result, the reaction force of the body lip elastically contacting the body panel may be too large, making it difficult to insert the molding leg, or the reaction force may be too small, causing the molding to be placed in the wrong position relative to the windshield. It will no longer be attached to the

(2) If you use an integrated molding in which the shape of the body lip changes depending on where it is installed, and two types of upper and side moldings with different cross-sectional shapes are continuously molded, it will not work as well as in conventional moldings. Eliminates the need to use corner fittings. Therefore, there is no joint surface at the corner of the molding, increasing its strength and improving the overall appearance of the molding. In addition, the number of molding parts is reduced to one, reducing the number of man-hours required for installation, thereby reducing costs.

(3) Furthermore, according to the molding apparatus according to the present invention, the shape of the body lip can be changed by moving the shutter in a predetermined direction during molding and changing the shape of the extrusion opening provided in the molding die. Different upper moldings and side moldings can be continuously molded to form an integrated molding.
