2. Description of the Related Art FIG. 13 is a perspective view of a part of a vehicle, in which 1 is a vehicle body, 2 is a vehicle body panel, 3 is a front window plate (window shield glass), 4 is a window molding, and U is its upper. , C is a corner portion, and S is a side portion. The window molding 4 is attached along the outer peripheral edge of the window plate 3 so as to shield the outer peripheral edge of the window plate 3.

In such a window molding, the tip of the molding body forms a flush surface between the upper portion U and the window plate 3 in the vicinity of the window plate 3 and gradually changes near the corner portion C. It is known that the side portion S is deformed so that the front end portion is separated from the window plate 3 and integrally formed so as to form a water receiving portion such as a groove. In the window molding 4, the water on the window plate 3 is collected at the water receiving portion at the side portion S and flows, and is prevented from flowing laterally to the side window side to block the view.

The above-mentioned window molding is formed continuously and integrally along the gap between the outer peripheral edge extending from the upper portion U of the window plate 3 through the corner portion C to the side portion S and the vehicle body panel. A long molding body, a mounting member that engages with the outer peripheral edge of the window plate 3 and / or the vehicle body panel 2, and a support wall that connects the molding body and the mounting member. It is located at a first position close to the outer surface of the window plate 3, and has a first position in which the tip portion is close to the outer surface of the window plate 3 and substantially forms a flush surface with the outer surface of the window plate 3. In the side portion S, the molding body is entirely formed on the outer surface of the window plate 3. The second position and / or the distal end separated from the outside of the vehicle further changes from the first position to a second position further separated from the outer surface of the window plate 3, and between the second position and the outer surface of the window plate 3. A water receiving portion is formed by the support wall, and the molding body is moved from the first position and the first posture to the second position at or near the corner portion C.
Is known to have a third position and / or a third posture that changes to a second position and / or a second posture (for example, JP-A-2-124314, JP-A-9-207).
560).

However, in such a conventional window molding, the support wall is folded and accommodated between the molding body and the mounting member in order to maintain the upper portion U at the first position and the first posture. However, since the thickness of the folded support wall is limited, it is difficult to set the molding body to a position and a posture as close to the outer surface of the window plate 3 as possible. On the other hand, when the thickness of the support wall is reduced in order to lower the position and posture in the upper portion U, the support force is weakened in the side portion S, and it is easy to deform to the window plate outer surface side when an external force acts. There is a problem.

The method described in.

[0008] The window molding of the present invention is formed of a material such as a resin, a metal deformed material, or a composite thereof, so as to have the above structure. In the case of a resin or a composite, it is obtained by forming a molding material by extrusion molding, and displacing and changing the position and orientation of the molding body so as to be different from each other. In the case of a metal profile, a molding material is formed by bending a metal strip material by roll forming or the like, or by profile extrusion of an aluminum alloy or the like, and is obtained by displacing and deforming so that the position and posture of the molding body are deformed. .

In other words, the window molding of the present invention comprises a molding material connecting the above-mentioned molding body and the mounting member and having a support wall formed thick at the side and thin at the upper. By accommodating the thinned support wall between the molding body and the mounting member, the molding body is located at the first position near the outer surface of the window plate, and the front end portion is close to the outer surface of the window plate. The molding body has a first position substantially forming a flush surface with the outer surface, and the molding body in the side portion has a second position entirely separated from the outer surface of the window plate to the outside of the vehicle and / or the tip portion has the first position. To the second position further away from the outer surface of the window plate than the position By reduction to form the water receiving portion is thickened support wall between the window plate outer surface, molding body at a corner portion or periphery thereof, the first
The second position and / or the second position is changed from the first position and the first position to the second position and / or the second position.

In the window molding thus obtained, since the support wall accommodated between the molding body and the mounting member in the upper portion is thin, the volume of the support wall is smaller than that of the side portion, and the position and posture of the molding body can be lowered. On the other hand, since the side wall can have a required thickness, the supporting force can be increased to prevent deformation.

[0011] By forming a window plate-side support wall and a vehicle body panel-side support wall as support walls, and making both the support walls thicker at the side portions and thinner at the upper portion, the support, position and posture of the molding body are provided. Can be easily and accurately controlled.

As a method of forming support walls having different thicknesses, after a support wall having the same thickness is extruded in a shape integral with the molding body and the mounting member, at least a part of the support wall is removed at the upper portion. Thus, molding materials having different thicknesses of the support wall between the side portion and the upper portion can be formed. As a result, the thickness of the support wall can be changed efficiently with a simple device and simple operation.

In this case, by removing at least a part of the support wall by a movable cutter that moves forward and backward toward the support wall, support walls having different thicknesses can be easily formed. A window molding in which the support wall on the window plate side and the support wall on the vehicle body panel side are thinned by lacking the outer resin in the upper portion can be manufactured by such a method, and is easy to manufacture.

As another method of forming the support walls having different thicknesses, the gap between the orifices forming the support walls is adjusted by moving the movable mold so that the support walls having the variable thickness are formed by the molding body and the mounting member. The molding material can be formed by extrusion molding into a shape integrated with the molding material. Accordingly, a molding material can be formed only by extrusion molding without requiring a separate processing step.

In this case, by changing the orifice so as to remove the inner portion of the support wall, the support wall on the window plate side and the support wall on the vehicle body panel side are thinned by lacking the inner resin in the upper portion. The formed molding material can be easily formed.
In such a molding material, the volume of the support wall is reduced in the upper portion from that of the side portion, and the area of the space sandwiched between the support wall on the window plate side and the support wall on the vehicle body panel side is increased to support the upper portion. The accommodation volume of the wall can be increased, thereby lowering the position and posture of the molding.

When the orifice is changed, the amount of resin supplied to the orifice is controlled (the amount of supply) according to the change (the size of the orifice area), so that the resin pressure in the extrusion die is kept constant. Extrusion molding can be performed stably, and a window molding having a uniform and excellent appearance and a stable shape can be manufactured.

By extruding a portion other than the support wall so as to have a deformable and stretch-resistant core material in the longitudinal direction, the molding material is prevented from expanding and contracting in the manufacturing process to maintain a stable shape. It is possible to control the operation of the movable die based on the extrusion amount of the molding material in a state where expansion and contraction is prevented or on the basis of the delivery amount of the core material to form a cross section of an accurate shape at an accurate position. . In addition, a molding with little expansion and contraction and high dimensional stability after molding can be obtained.

By providing a stretchable decorative strip on the outer surface of the molding body, a decorative strip that changes in response to a change in the position and posture of the molding body can be formed, and the decorativeness can be enhanced. Can be.

In this case, after the decorative strip on which the peelable film is adhered is integrated and extruded, the peelable film is peeled off to form a molding material, so that the decorative strip passes through the extrusion die. Processing can be performed in a state where the surface is prevented from being scratched and protected, and a highly decorative window molding can be manufactured.

The above-described window molding is used by being attached along a gap between an outer peripheral edge extending from an upper portion of a window plate to a side portion through a corner portion and a vehicle body panel in a front window of a vehicle. In the use (running) state, the front end of the molding main body is close to the outer surface of the window plate in the upper portion and substantially forms a flush surface with the outer surface of the window plate. Smaller,
Rainwater on the window plate is allowed to flow across the molding to the roof side. On the other hand, in the side portion, the water receiving portion is formed at a distance from the outer surface of the window plate, so that rainwater on the window plate is collected, flows along the water receiving portion, and is prevented from flowing to the side window side. Blocking the view at the window is prevented.

[0021]

According to the molding of the present invention, the supporting wall is formed to be thick at the side portion to support the molding body, and the upper portion is formed to be thin so as to reduce the volume of the supporting wall and accommodate it between the molding body and the mounting member. As a result, the position and orientation of the molding body can be reduced in the upper portion, and the supporting force when the position and / or orientation is increased in the side portion can be increased to prevent deformation.

According to the method of manufacturing a molding of the present invention, since the above-described molding material is processed, the above-described window molding can be efficiently manufactured.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is an s-s cross-sectional view of FIG. 13 showing an attached state of the window molding of the embodiment.
2B is a cross-sectional view taken along the line uu, and FIG. 2A is a cross-sectional view taken along the line c-c.

The window molding 4 is attached along the gap D between the outer peripheral edge extending from the upper portion U of the window plate 3 through the corner portion C to the side portion S and the vehicle body panel 2, and is a integrally formed length. A molding body 5 having a length and a holding wall 7 of a mounting leg 6 as a mounting member provided on the back side of the molding body 5 are supported via a support wall 8 on the window plate 3 side and a support wall 9 on the vehicle body panel 2 side. They are connected and integrally formed of rubber or thermoplastic synthetic resin.

The decorative surface of the molding body 5 has a different color from the outer surface of the molding body 5 and has a glitter film, a coloring tape, etc. based on a thermoplastic resin which can be extended by heating to a predetermined temperature. A part of the decorative strip 11 is embedded and fixed along the entire length along the longitudinal direction, and a lip 12 is integrally fixed to the vehicle body panel 2 side with an elastic soft resin. The mounting member is composed of a holding wall 7 and mounting legs 6, and one or more deformable and non-stretchable core members 13 such as a thin metal wire or a glass fiber thread are embedded in the mounting legs 6 for mounting. An end portion of the mounting leg 6 is integrated with the leg 6, and a distal end portion of the mounting leg 6 is formed with a locking portion 14 which is bent toward the window plate 3 and is locked on an outer peripheral edge of the window plate 3. The fins 15 are integrally formed so as to be elastically deformable with a soft resin having elasticity so that the mounting legs 6 are pressed against the window plate 3 side.

The heights Hu, Hc and Hs of the side flanges 2a of the upper portion U, the corner portions C and the side portions S of the body panel 2 from the bottom flange 2b are Hu <Hc <Hs.
The height Hu of the upper portion U starts to increase and gradually changes in the middle of the corner portion or near the corner portion as shown in FIG.

The window molding 4 is formed in an arc-shaped cross section so that the support wall 8 on the window plate 3 side and the support wall 9 on the vehicle body panel 2 side are convex toward each other. , 9 are deformed, the first to third positions and the first to third postures are mutually changed. Reference numerals 8a and 9a indicate the positions of the inner surfaces of the upper portions U of the support walls 8 and 9, respectively. Assuming that the thicknesses of the support walls 8, 9 at the upper portion U, the side portion S, and the corner portion C are a first thickness Tu, a second thickness Ts, and a third thickness Tc, respectively, Tu <Tc <Ts.
It has become. The drawing shows a case where the thickness of the support walls 8 and 9 changes by removing the inside (inside), but the thickness may change by removing the outside (outside). And both may change. Further, the thickness of the holding wall 7 in the upper portion may be smaller than that in the side portion. A continuous V-shaped small groove is formed in the inner surface of each of the support walls 8 and 9 at a substantially middle portion, so that when the upper portions accommodate the support walls 8 and 9, the support walls 8 and 9 start to bend at the V grooves. Can be accurately and stably deformed.

In this case, the molding main body 5 is located at a first position close to the outer surface of the window plate 3 in the upper portion U, and the front end portion 16 contacts the outer surface of the window plate 3 to make contact with the outer surface. Has a first position to substantially form a flash surface, and has a side portion S
In such a case, the tip portion 16 is displaced from the outer surface of the window plate 3 toward the outside of the vehicle so as to be located at a second position, and the distal end portion 16 is further separated from the outer surface of the window plate 3 than the first posture. It has a second posture of deforming and forming the water receiving portion 17 with the window plate 3, and in the vicinity of the corner C, from the first position and the first posture to the second position and the second position. It has a third position and a third posture that change to a posture.

The respective heights Ku, Ks and Kc of the molding body at the first to third positions in the upper portion, side portions and corner portions (heights from the outer surface of the window plate 3) are Ku <Kc <Ks. It has become. The reference position K of the height of the molding body 5
Is based on the end near the body panel 2. A plane parallel to the outer surface of the window plate 3 in the first to third positions in the upper portion, the side portion, and the corner portion is set to an angle of 0 degree, and
Angles -Gu, Gs, -Gc intersect with -G
u <−Gc <Gs. Here, the symbol-indicates a negative angle. Distances Lu, L between the tip 16 of the molding body 5 and the outer surface of the window plate 3 at the upper, side, and corner portions, respectively.
s and Lc are Lu <Lc <Ls, and Lu = 0, Ls <Hs
It has become.

The support walls 8, 9 are thick at the side portions S, thin at the upper portions U, and have intermediate thicknesses at the corner portions C.

The support walls 8 and 9 have the most extended shapes at the side portions S, and a portion surrounded by the molding body 5 and the holding wall 7 forms a hollow portion 18. In the corner portion C, the support walls 8, 9 start to be deformed so as to be folded, so that the cross-sectional area of the hollow portion 18 becomes smaller than that of the side portion S, and in the upper portion U, the support walls 8, 9 are folded and become the support walls. The members are welded to each other, and the cross-sectional area of the cavity 18 is minimized.

The hollow portion 18 is preferably continuous with the corner portion C and the side portion S in the upper portion U along the longitudinal direction.
When there is a risk of the airflow being blocked, it is preferable to form a V-shaped hollow communication passage 18a over the entire length so as to allow ventilation. 21 is an opaque print layer formed on the outer periphery of the rear surface of the window plate 3, 22 is a dam rubber,
23 is an adhesive.

The above-mentioned window molding 4 is used for the window plate 3 in the front window of the vehicle.
Is mounted along the gap D between the outer peripheral edge extending from the upper portion U to the side portion S via the corner portion C and the vehicle body panel 2. In this case, the window molding 4 is attached to the vehicle body panel 2 after the window molding 4 is attached to the outer peripheral edge of the window plate 3 in advance. There is a case to install with. At this time, the window plate 3 was held between the holding wall 7 and the locking portion 14, the side flange 2 a of the vehicle body panel 2 was pushed by the fin 15, and the mounting leg 6 was pressed against the end face side of the window plate 3 by elastic force. In this state, it is adhered and fixed by the adhesive 23.

In the mounted state, the distal end portion 16 of the molding main body 5 contacts the outer surface of the window plate 3 at the upper portion to form a flush surface, so that the air resistance during running of the vehicle decreases and the Is allowed to flow to the roof panel side across the molding body 5. In the side part, since the water receiving part 17 is formed at a distance from the outer surface of the window plate 3, the rainwater 1 on the window plate 3
9 is collected and flows along the water receiving portion 17, and the rainwater is prevented from crossing the molding body and flowing to the side window side, thereby preventing the view at the side window portion from being obstructed.

In the above-described window molding 4, since both the position and the posture of the molding body 5 are changed, the design of the body panel 2 and the molding body 5 are changed.
Even if the posture of the camera is not largely changed, the one having high water receiving capacity and high decorativeness can be obtained.

That is, the molding body 5 is located at the first position at a height of Ku close to the outer surface of the window plate 3 in the upper portion, and the tip portion 16 contacts the outer surface of the window plate 3 so that the flash surface is formed. It has a first attitude of an angle of -Gu to be formed, and the side portion is displaced from the outer surface of the window plate 3 to a second position at a height of Ks, which is separated from the outer surface of the window plate 3 to the outside of the vehicle. 16 has a second posture in which the angle of Gs is changed so as to be further away from the outer surface of the window plate 3 than the first posture to form the water receiving portion 17 between the window plate 3 and the corner; Near the part
And the third position and the third position changing from the position and the first position to the second position and the second position, the height of the side flange 2a of the vehicle body panel at the upper portion and the side portion is reduced. If you do not want to increase the difference, that is, the molding body 5 in the upper part and the side part
Is small, the water receiving capacity can be increased by changing the posture by displacing the molding body 5 or its distal end portion 16 with the deformation of the support walls 8 and 9, and even in this case, the molding can be performed. Since the position of the main body 5 has changed, the amount of change in the posture may be small, and the appearance is not impaired. As is clear from the above description, the difference between the heights Ls, Lu, and Lc is determined by the heights Ks, Ku, and Ks.
Since this can be achieved by a combination of the difference between c and the difference between the angles Gs, Gu, and Gc, it can be more easily dealt with than when the change is achieved only by the angle G or the height K.

In this case, in the first position and the first position of the upper portion U, the supporting walls 8 and 9 are thin, so that the volume is reduced and the space between the molding body 5 and the holding wall 7 of the mounting member is increased. The molding body 5 is housed in a small folded state, so that the position and posture of the molding body 5 can be lowered. Then, the second position of the side portion S and the second position
In the posture, the supporting walls 8 and 9 are thick, so that the supporting force of the molding main body 5 is increased, and deformation due to external force is prevented.

FIG. 2B is a cross-sectional view taken along the line s-s in FIG. 13 showing a mounting state at a side portion of the window molding of another embodiment in which the mounting member is also locked to the vehicle body panel. This window molding 4 is configured in substantially the same manner as described above, except that a locking member 25 protrudes from the lip 12 side of the molding body 5 to the back surface side.
A fastener 27 previously fixed to a side flange 2a of the vehicle body panel 2 with an adhesive material 26 such as a double-sided adhesive tape.
Is configured to engage with the locking member 27a. It is preferable that the fastener 27 be continuously attached to the left and right sides, the left and right corners, and the upper portion of the side flange 2a.

Such a window molding 4
Even if a force is applied from the vehicle body panel 2 side to the window plate 3 side, the vehicle body 2 is prevented from moving off or falling down to the vehicle body panel 2 side and the window plate 3 side, and maintains a stable mounting state. Other operations and effects are the same as those in the above-described example.
