DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a molding for covering a gap when a plate-like component such as a window glass of a vehicle such as an automobile is attached to a vehicle body panel.

(Prior Art) Generally, a window glass (window plate) is provided on a vehicle body panel.
When attaching a plate-like part such as, when using a liquid adhesive to bond it, polyvinyl chloride (PVC), vinyl acetate (PVA), or polyvinyl chloride (PVA) in the gap between the outer peripheral edge and the vehicle body (roof or pillar) panel. A molding made of soft synthetic resin such as an ionomer is attached, and the decoration and the seal are combined to prevent a gap.

FIG. 14 is a cross section of a conventional molding and is shown in FIG.
AA cross section is shown.

In FIG. 2, the vehicle body 1 has a window plate 2 attached to the rear portion thereof, and a long molding 3 is bent around the peripheral portion of the vehicle body 1 at the corner portions so that the straight portions and the corner portions are integrally mounted.

In FIG. 14 showing a cross section, a molding 3 mounted in a gap between the plate 2 and the vehicle body panel 4 has a thick head portion 5 for covering the gap and a thick wall portion 5 extending so as to project downward from the head portion 5. The legs 6 and the head 5 extend toward the vehicle body panel 4 side,
In addition, the leg 6 is a tongue-shaped lip that extends obliquely at an obtuse angle α with respect to the bending neutral line XX of the molding 3.
Shield lip 7 and legs 6 that are made softer than
Holding part 8 extending in the same direction from the lower end to the head 5
And an outer lip-shaped contact portion that extends obliquely from the lower end of the leg portion 6 toward the shield lip 7 in the same direction at a substantially acute angle β with respect to the neutral line XX (the body panel step portion when mounting the molding 3). The inner lip abutting portion (which contacts the outer peripheral edge of the plate 2 when mounted as described above) and the plate housing groove 11 formed by the head portion 5 and the holding portion 8 extends obliquely from the back surface of the head portion 5 Abutting against) 12 and formed into a long length by extrusion molding.

The long molding 3 is cut into the length of the outer periphery of the plate 2, the outer peripheral edge of the plate 2 is inserted into the plate accommodating groove 11, and the bending neutral line X-
By bending around X, applying a liquid adhesive 13 to the back surface of the plate 2 and adhering it to the vehicle body panel 4, and covering the gap between the plate 2 and the vehicle body panel 4 with the molding 3, the role of decoration and sealing I am making

(Problems to be solved by the invention) When assembling, when the molding 3 is bent at the corner portion along the outer peripheral edge of the plate 2, the shield lip 7 located outside the bending neutral line XX and the outer lip. A tensile force acts on the contact portion 9.

As a result, the shield lip 7 is prone to fall and deform in the direction of the arrow A at which the obtuse angle α with respect to the bending neutral line XX becomes large as shown by the solid line in FIG. 14, and as a result, the shield lip 7 floats up from the vehicle body panel 4 and a gap is formed. It happened.

Further, the outer lip-shaped abutting portion 9 is also deformed in the direction of the arrow B, and the abutting force on the vehicle body panel step portion 10 is slightly reduced,
There is no problem.

In order to solve the above problems, the present invention examines the deformation or behavior of the shield lip of the molding, and aims to provide an effective molding for preventing the shield lip from deforming in the direction away from the vehicle body panel. .

[Means for Solving the Problems] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention continuously mounts along a gap between an outer peripheral edge of a plate-shaped component having a corner and a vehicle body panel of a vehicle. In a long molding made of synthetic resin, a head covering the gap, and a leg extending inward from the back surface of the head so as to integrally project into the gap,
The side wall of the head portion has a thickness smaller than that of the head portion and protrudes toward the vehicle body panel side by a predetermined length to extend so as to cover the gap from the outside of the vehicle, and forms an approximately obtuse angle with respect to the bending neutral line of the molding. With a shield lip that extends diagonally outside the vehicle,
The pulling ridge protruding from the back surface of the shield lip and extending toward the inside of the vehicle, and the pulling ridge extending from the leg portion toward the pulling ridge at an angle with respect to the bending neutral line, In order to prevent the obtuse angle from increasing due to bending, the pulling ridges and the pulling ridges are formed so as to be connected to or in contact with each other in at least the bent state.

(Action) When bending along the radius of curvature of the outer peripheral edge of the plate to mount the molding, the shield lip that is positioned outside the bending neutral line of the molding and extends obliquely with a generally obtuse angle to the bending neutral line Since tensile stress acts, the tip tends to rise and deform so as to increase the obtuse angle in order to relax the tensile stress and to deform so as to approach the bending neutral line.

However, the tow ridge that is inclined with respect to the bending neutral line,
Since it is deformed so as to approach the bending neutral line, the obtuse angle of the shield lip is reduced in the direction in which the obtuse angle of the shield lip is reduced through the pulling protrusions connected to the shield lip (downward in the drawing).
To prevent the deformation of the tip.

(Embodiment) An embodiment of the present invention will be described below with reference to the sectional views of FIGS.

1 to 5 show the first embodiment, and first,
The configuration will be described.

In each drawing, parts having the same structure as those of the conventional one shown in FIG. 14 are denoted by the same reference numerals, and the description of the structure is omitted.

The molding 23 shown in FIG. 1 shows a state in which it is not bent, and a thin pulling protrusion 24 extending from the back surface of the shield lip 7 toward the outer lip-shaped contact portion 9 and an upper portion of the leg portion 6 (shield). The pulling ridge 25 projecting obliquely downward from the vicinity of the base of the lip 7 (that is, diagonally toward the tip of the pulling ridge 24) and the tip ends of the pulling ridge 24 and the pulling ridge 25 respectively. It is provided with an enlarged portion 26 which is connected to each other and has a wall thickness thicker than each of these portions.

FIG. 3 shows the mounted state of the molding 23 of FIG.
FIG. 4 is a perspective view of a corner portion of the plate 2 in the mounted state, and FIG. 5 shows a state of being bent along the corner portion by a solid line. Towing ridge 25 shown by the chain line in Fig. 5
When the molding 23 is bent around the bending neutral line XX, it deforms so as to approach the bending neutral line XX as a solid line, and by this deforming action, the pulling protrusion 24 is pulled from the chain line position to the solid line position, The pulling protrusion 24 pulls the shield lip 7 in the arrow C direction.

Since the enlarged portion 26 is thicker than the pulling protrusions 24 and the pulling ridges 25, it is difficult to extend even when the molding 23 is bent. The above approaching movement to the bending neutral line XX is surely performed.

In the illustrated example, the core member 27 is also provided on the bending neutral line XX of the leg portion 6,
A core material 27 is embedded in the enlarging portion 26 over the entire length of the molding 23.

The core material 27 uses, for example, a glass fiber strand material that is flexible but poor in elasticity, and when the core material 27 is bent, the core material 27 is difficult to extend, so the bending neutral line X- of the enlarged portion 26-
The above-mentioned approach movement to X is further promoted and surely performed.

In addition, the core member 27 on the bending neutral line XX increases the tensile strength of the molding 23 and, while maintaining an appropriate softness against bending, allows the shield lip thin portion to be deformed by extension or compression. It is a thing.

However, the core material 27 is not always necessary.

Further, in the illustrated example, a groove 28 is provided at the base of the towing protrusion 25, and a groove 29 is also provided inside the connecting portion between the pulling protrusion 24 and the towing protrusion 25 over the entire length of the molding 23. The pulling ridge 25 and the pulling ridge 24 are devised so that the approaching movement to the bending neutral line XX at the time of pulling is performed with less resistance.

However, these concave grooves 28 and 29 are not always necessary.

Next, the operation of the above embodiment will be described.

The long molding 23 formed as shown in FIG. 1 is cut into a predetermined length, and the plate accommodating groove 11 is inserted into the outer peripheral edge of the plate 2 and attached to the vehicle body 1.

At this time, when bending along the radius of curvature of the radius R of the corner portion of the plate 2 as shown in FIG. 4, the expansion / contraction amount is 0 on the bending neutral line XX, but on the bending outer side with respect to the bending neutral line XX. Tensile stress and compressive force act on the bending center line XX on the bending center side.

As a result, the shield lip 7 is as shown by the solid line in FIG.
In order to alleviate the tensile stress, it tries to deform so as to approach the bending neutral line XX, and it tries to float and deform in a direction in which the obtuse angle α with respect to the bending neutral line XX becomes large (that is, the upward direction A in the drawing).

On the other hand, since the tow ridge 25 is deformed in the direction approaching the bending neutral line XX as shown by the solid line in FIG. 5, the tow ridge 25 and the pulling ridge 24 connected to the tow ridge 25 are connected to the shield lip 7. This will prevent the floating deformation. Since the enlarged portion 26 is thicker than the pulling protrusion 24 and the pulling ridge 25 and has the core material 27 embedded therein, it is poor in elasticity. Therefore, the pulling force by the pulling ridge 25 is strong and the deformation of the shield lip 7 is more prevented. It will be certain.

Therefore, when the adhesive 13 applied to the vehicle body panel 4 is moved toward the fifth
As shown in the solid line in FIG. 3, when the holding portion 8 is adhered to the vehicle body panel 4 with the molding 23 approached as shown in the figure,
The shield lip 7 is in close contact with the outer surface of the vehicle body panel 4, and no gap is generated between the shield lip 7 and the vehicle body panel 4.

At this time, the outer lip-shaped contact portion 9 is connected to the body panel step portion 10
In addition, the inner lip-shaped contact portions 12 are in close contact with the outer peripheral edge of the plate 2, respectively.

The molding 33 of the second embodiment shown in FIG. 6 is of an insert type, and by providing a plurality of outer lip-shaped contact portions 39, the adhesion to the vehicle body panel step portion 10 is strengthened, and the inner lip is formed. The contact portion 38 has a thin wall and is configured to be easily elastically deformed.

That is, the window plate 2 is attached to the vehicle body panel 4 with the adhesive 13
In the case of the type in which the molding 33 is inserted into the gap between the window plate 2 and the vehicle body panel 4 after being fixed via the above, the inner lip-shaped contact portion 38 is provided on the back surface of the plate 2 and the outer surface of the vehicle body panel 4. It will be easily inserted into the gap. Also in this case, the molding 33 is the fourth
When the plate 2 is bent along the radius of curvature of the radius R of the corner portion as shown in the drawing, the rising deformation of the shield lip 7 is prevented by the pulling protrusion 24, the pulling protrusion 25 and the enlarged portion 26.

The molding 43 of the third embodiment shown in FIG.
It is not provided with the enlarged portion 26 in the insertable molding shown. In the molding of FIG. 1 as well, the enlarging portion 26 may not be provided and the pulling protrusion 24 and the towing protrusion 25 may simply be connected.

In the molding 53 of the fourth embodiment shown in FIG. 8, the pulling protrusion 34 and the towing protrusion 35 are formed in a separated state, and when bent in the same manner as described above, the towing protrusion 35 is deformed. The shield lip 7 is devised so as to exert the above-mentioned deformation preventing action.

That is, the long pulling ridge 35 extending from the leg 6 is opposed to the short-thickness pulling ridge 34 protruding from the back surface of the shield lip 7.
Is formed in an arc shape, and the tip of the
Close to the outside of 34.

When the molding 53 is bent along the radius of curvature of the corner radius R of the plate 2 as shown in FIG. 4, the tip of the pulling ridge 35 is deformed in the direction of arrow D by the action of tensile force, and the pulling ridge 35 is pulled. The contact protrusion 34 engages with and pushes it, and the pulling protrusion 34 is displaced in the arrow E direction with the base of the shield lip 7 as the center of rotation. Along with this, the shield lip 7 deforms and moves in the direction indicated by the arrow F toward the bending neutral line XX, and the deformation of the shield lip 7 in the floating direction is prevented during the bending operation.

Since the towing ridge 35 is formed in an arc shape as described above, the enlarged portion 26 of the pulling tongue 34 can slide on the towing ridge 35 without difficulty during the above-mentioned insertion.

In the embodiment shown in FIG. 8, since the core material 27 is embedded in the tip of the pulling protrusion 34, the core material 27 bends when bent.
By moving so as to approach XX, the movement of the pulling protrusion 34 in the direction of the arrow E is further promoted.

The molding 63 of the fifth embodiment shown in FIG. 9 is one in which the enlarging portion 26 and the core material 27 are not provided in the pulling protrusion 34.

In the molding 73 of the sixth embodiment shown in FIG. 10, a thin pulling protrusion 44 extending from the back surface of the shield lip 7 is formed by connecting to the leg portion 6, and an enormous amount is provided at the tip of the pulling protrusion 45. Department
The 26 is arranged in a long state to approach the middle portion of the pulling protrusion 44 from the outside.

When the molding 73 is bent along the radius of curvature of the radius R of the corner portion of the plate 2, the pulling ridge 45 is deformed in the direction of arrow G by the action of the tensile force, and the pulling ridge 44 is moved in the same direction by the enlarged portion 26. It is pushed by and bends. Due to this bending action of the pulling protrusion 44, the shield lip 7 moves in the direction of the arrow H toward the bending neutral line XX, and the floating deformation of the shield lip 7 during the bending operation is prevented.

The seventh embodiment shown in FIG. 11 does not include the enlarged portion 26 and the core material 27 in the sixth embodiment.

The molding 93 of the eighth embodiment shown in FIG. 12 has a hook 54a formed at the tip of the pulling protrusion 54, while it extends from the leg portion 6 obliquely downward, that is, in a direction away from the pulling protrusion 54. Further, a pulling ridge 55 is provided which is integrally folded back and extends in a direction approaching the pulling ridge 54, and a hook 55a formed at the tip of the pulling ridge 55 is brought closer to the hook 54a.

When the molding 93 is bent, the pulling ridge 55 moves in the arrow J direction, and the hooks 55a and 54a engage with each other, thereby pulling the shield lip 7 in the arrow K direction.

The molding 103 of the ninth embodiment shown in FIG. 13 is provided with an enlarged portion 36 in the intermediate portion of the pulling ridge / towing ridge 64 formed to connect the shield lip 7 and the leg 6 to each other. 27 is buried in the enormous part 36.

When the molding 103 is bent, the enlarged portion 36 is difficult to extend, so that it moves together with the core material 27 so as to approach the bending neutral line XX, whereby the pulling ridge / towing ridge 64 is deformed in the direction of the arrow L, and the shield lip 7 Will be moved in the direction of arrow M toward the bending neutral line XX.

The present invention is not limited to the window molding described above, but can be applied to molding when mounting other plate-shaped parts such as a sunroof.

[Effects of the Invention] As described above, the present invention bends the pulling ridges and the legs that connect or contact each other in a state where the molding is bent along the radius of curvature R of the corner of the window plate. Towing ridges that extend obliquely to the neutral line,
Since the shield lip and the leg portion are provided, the shield lip is prevented from being lifted up and deformed when bent, and the problem caused by use along the corner R of the long molding window plate is eliminated.

Further, there is an effect that it is possible to deal with a single molding, it can be used even in a small corner without any trouble, it is possible to prevent variation during assembly, and it is possible to prevent cost increase.
