2. Description of the Related Art Generally, a window molding is attached to the peripheral edge of a window glass attached to a window opening of a vehicle body panel. That is, a continuous elongated gap is formed from the upper part to the side part between the peripheral end surface of the window glass and the opening edge of the window opening of the vehicle body panel. A molding body is inserted and sealed. This mall body is
It consists of a long extruded member and is continuously extruded from an extrusion forming port provided in a die.

[0003] In such a wind molding, as described in, for example, Japanese Utility Model Publication No. 57-41051 or Japanese Utility Model Publication No. 58-23699, it is conventional to provide a water conduit from the upper part to the side part of the molding body. generally known. This conduit drains rainwater and the like adhering to the windshield to the outside of the vehicle to prevent it from falling into the interior of the vehicle.

0004

[Problem to be solved by the invention] However, in general,
When wind molding is extruded, the cross section is extruded in a constant shape, so the formation position of the above-mentioned water conduit with respect to the cross section is constant in the longitudinal direction. Therefore, in the conventional water conduit, it is difficult to guide rainwater etc. to a desired position, and the function of the water conduit is not sufficient.

On the other hand, Japanese Patent Application Laid-open No. 1-195032 states,
A molding body in which a water conduit is formed by a "weir" made of ridges is first extruded into a shape with a constant cross section, and then the ridges forming the "weir" are partially cut away. It is disclosed that According to this one,
Although the protruding height of the "weir" can be adjusted arbitrarily,
The formation position of the water conduit with respect to the cross section is constant in the longitudinal direction, and therefore, similarly to what was described above, it is difficult to guide rainwater etc. to a predetermined position.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wind molding for an automobile in which a water conduit can be provided with a good water guiding function.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the invention according to claim 1 forms the water conduit by a raised part rising from the molding body toward the outdoor side, and By displacing in the longitudinal direction the formation position of the protrusion in the cross section orthogonal to the longitudinal direction, the formation position of the water conduit in the cross section can be displaced in the longitudinal direction.

[0008] Furthermore, the invention according to claim 2 is such that the water conduit is formed by extrusion molding a protrusion in a shape that rises from the molding body toward the outdoor side, and the cross section perpendicular to the longitudinal direction of the molding body By displacing the extrusion forming port of the die, the formation position of the protrusion is longitudinally displaced, and the formation position of the water conduit in the cross section is longitudinally displaced.

Furthermore, the invention according to claim 3 is the automobile window molding according to claim 1, in which the height of the protruding portion of the protruding portion in the cross section orthogonal to the longitudinal direction of the molding body is adjusted in the longitudinal direction. at least partially, and the depth of formation with respect to the cross section of the water conduit is varied in the longitudinal direction.

0010

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, as shown in FIG. 1, a back window glass 2 is attached from the outside to the window opening of a back door panel 1 that is attached to the rear of an automobile so that it can be opened and closed in the vertical direction. A molding body 3 made of an elongated extruded sealing member is installed in an elongated gap formed between the peripheral end surface of the back window glass 2 and the window opening edge of the back door panel 1. The molding body 3 includes an upper molding body 4 attached to the upper edge of the back window glass 2, and a side molding body 5 attached to both side edges of the back window glass 2.
and a lower side molding body 6 attached to the lower edge of the back window glass 2, which are integrally and continuously formed by extrusion molding. A first embodiment of such an automotive window molding is shown in FIGS. 2-5.

First, the upper side molding body 4 is shown in FIGS. 2 and 3.
and has the structure shown in FIG. That is, the window opening edge portion of the back door panel 1 is bent so as to have a recessed step toward the indoor side (lower side in FIG. 3), and is bent toward the back window glass 2 side via the indoor side bent portion 1a. An extending flange portion 1b is provided. The back window glass 2 is stacked on the outdoor side surface (top side in FIG. 3) of the flange portion 1b via the dam rubber 7, and the top end surface (right side in FIG. 3) of the back window glass 2 is on the indoor side. It is arranged opposite to the bent portion 1a with a constant interval therebetween. A space defined by the back window glass 2, the indoor bent portion 1a, and the flange portion 1b is filled with adhesive 8, and the adhesive 8 allows the above-mentioned members 2, 7, 1a, 1b are fixed.

Further, an upper side of the molding body 3, that is, an upper side molding body 4 is attached to the gap between the back window glass 2 and the indoor bent portion 1a. This upper side molding body 4 includes a glass engaging part 401 that fits into the back side (lower side in FIG. an elastic lip 402 extending toward the portion 1a; a strut portion 403 extending from the glass engaging portion 401 toward the outdoor side (upper side in FIG. 3) in the thickness direction of the back window glass 2; a lip-shaped inner decorative molding portion 404 extending from the outdoor side (upper side in FIG. 3) toward the outdoor surface of the back window glass 2; and an indoor side bending portion opposite to the extending direction of the inner decorative molding portion 404 It is provided with an outer decorative molding part 405 that branches off from the pillar part 403 and extends toward the part 1a.

The glass engaging portion 401 has a stepped shape with a substantially triangular cross section that fits into the rear (lower side in FIG. 3) edge of the back window glass 2. It is fitted into the indoor side twill part (lower right side twill part in FIG. 3) at the edge. Further, the elastic lip 402 is pressed against the indoor bent portion 1a surface of the back door panel 1 in a bent state, and the repulsive force due to the bending causes the support portion 403 and the glass engaging portion 401 to be pressed against the back window glass 2. This acts as a biasing force that presses the glass engaging portion 401 toward the side, and the engaging stepped portion of the glass engaging portion 401 is press-fitted to the edge portion of the back window glass 2 by the pressing force. Due to the fitting relationship between the glass engaging portion 401 and the back window glass 2, the upper side molding body 4 is engaged with the back door panel 1 without falling off and is held at a fixed position.

01-506,12. Also, this side molding body 5 is located on the side upper side near the corner (Fig. 3).
The cross-sectional shape is continuously displaced from the corner to the lower side, and the lower side farther from the corner has the cross-sectional structure shown in FIG. 4, for example. However, in this case, the only difference in the cross-sectional structure from FIG. 3 to FIG. is maintained.

The formation position of the raised portion 506 is gradually moved toward the outside of the vehicle from the upper side side shown in FIG. 3 to the lower side side shown in FIG. The amount is being gradually reduced. More specifically, first, the raised portion 506 provided on the upper side portion near the corner portion extends from the inner peripheral edge (the left side edge in the figure) of the inner decorative molding portion 504, as shown in FIG. 6a. A side surface that protrudes diagonally inward and is formed by a space having a triangular cross section between the glass side surface (left side surface in the figure) 506a of the raised portion 506, the inner decorative molding portion 504, and the back window glass 2. A water conduit 12 is defined.

In a portion slightly lower than this, as shown in FIG. 6b, the formation position of the raised portion 506 is moved slightly outward (to the right in the figure). At this time, the raised portion 5
The protrusion height of 06 is maintained as it is, and this figure 6
The protrusion 506 at the position shown in b protrudes in a direction perpendicular to the surface of the back window glass 2. Along with the movement of the formation position of the raised portion 506,
The formation position of the side water conduit 12 is also continuously displaced in the longitudinal direction toward the outside of the vehicle. Furthermore, in a region below this, the protrusion height of the raised portion 506 is gradually reduced while the formation position of the raised portion 506 is maintained as it is.

In other words, in the lower part shown in FIG. 6c, the protrusion height of the protrusion 506 is slightly reduced, while the formation position of the protrusion 506 is maintained as described above. In the lower part shown in FIG. 6d, the protruding height of the ridge 506 is almost gone.

In a portion further below the position shown in FIG. 6d, the protruding portion 506 is not formed and has disappeared. Along with this, the side water conduit 12 has also disappeared. As described above, in this embodiment, the formation position of the side water conduit 12 is continuously displaced in the longitudinal direction by the formation position displacement and the protrusion height displacement of the raised portion 506, and is simultaneously moved toward the outside of the vehicle. The lower end portion of the side water conduit 12 is open to the outside of the vehicle.

When the back door panel 1 is opened upward, rainwater etc. on the back window glass 2 moves toward the upper side molding body 4 side and is sent to the side side water conduit 12 through the upper side water conduit 11. It will be done. Since the lower end portion of the side headrace 12 is opened after being displaced toward the outside of the vehicle as described above, rainwater etc. that have been guided through the side headrace 12 are transferred to the side headrace 1.
2 is discharged from the lower end toward a predetermined position outside the vehicle. The destination of rainwater and the like can be arbitrarily set by appropriately adjusting the positional displacement of the side water conduit 12.

Next, the molding body manufacturing apparatus according to the above-described embodiment will be explained. 7 and 8, the molding body 3
A die configuration for extrusion forming is shown. The die in this device includes a first die 21, a second die 22, and a third die 23, which are arranged in parallel in the extrusion direction of the molding body 3 (perpendicular to the plane of the paper). 1 die 21
is installed in a fixed state, and the second die 22
is provided so as to be rotatably movable on the front side of the first die 21, and the third die 23 is provided so as to be movable in parallel along the front side of the second die 22. The first die 21 is provided with an extrusion forming opening 211 corresponding to the outer shape of the molding body (4, 5) having the above-described structure excluding the protruding parts (406, 506), and the second die 22 is provided with an extrusion forming port 221 for molding both sides of the raised portion (406, 506), and the third die 23 is provided with an extrusion forming port 221 for molding both sides of the raised portion (406, 506). An extrusion forming side 231 is provided for forming.

The second die 22 is formed into a disk shape, and is rotatably supported by a plurality of guides 222. Further, a rack tooth 223 is cut into a part of the outer circumference of the second die 22 over a predetermined arc length, and a pinion gear 224 that meshes with the rack tooth 223 is fixed to the output shaft of a drive motor 225. ing. On the other hand, the third die 23 is held so as to be able to move in parallel, and a support shaft 232 protruding from the third die 23 is connected to an output shaft of a drive motor 234 via a rotational movement conversion mechanism 233. has been done.

According to the manufacturing apparatus in this embodiment, by operating the drive motor 225, the first
The set position of the second die 22 with respect to the die 21, that is, the formation position of the raised portions (406, 506) is adjusted as appropriate. Furthermore, by operating the drive motor 234, the set position of the third die 23 with respect to the second die 22, that is, the height of the protruding portion (406, 506) can be adjusted as appropriate. That is, by setting the molding body in the position shown in FIG. 7, a molding body having a cross-sectional shape corresponding to that shown in FIG. 6a is obtained.
When set in the position shown in FIG. 8, a molding body having a cross-sectional shape corresponding to that shown in FIG. 6d is obtained. Therefore, the molding bodies 4 and 5 having different cross-sectional shapes in the longitudinal direction as described above are successively formed.

9 to 11 show a second embodiment in which the present invention is applied to a front window glass 32. In FIGS. In the description of this second embodiment, the same components as those of the first embodiment described above will be illustrated with the reference numeral 40 and the reference numeral 50 in the first embodiment replaced with 34 and 35, respectively, and the explanation thereof will be omitted. , only the different parts will be explained below.

First, as shown in FIG. 1, the front windshield 32 is attached from the outside to a window opening surrounded by a roof panel 30 and a pillar panel 31. As shown in FIGS. 10 and 11, an elongated sheet is formed in a gap continuously formed between the peripheral end surface of the front windshield 32 and the window opening edges of the roof panel 30 and pillar panel 31. A molding body 33 made of an extruded seal member is attached. The molding body 33 includes an upper molding body 34 attached to the upper edge of the front window glass 32 and a side molding body 35 attached to the side edge of the front window glass 32. These molding bodies 34,
35 is also integrally and continuously extruded.

First, the upper molding body 34 has the structure shown in FIG. 9, and is different from the upper molding body 4 in the first embodiment described above (see FIG. 3) in that the outer decorative molding part 345 is The pillar part 343 is branched from the middle part on the back side, the formation position of the raised part 346 is shifted to the outside (upper side), and the glass engaging part 341 is slightly offset from the glass surface. The two points are that a long contact portion is provided and that an elastic lip (represented by reference numeral 402 in FIG. 3) is not provided.

The outer decorative molding portion 345 is connected to the support portion 343.
It branches from the middle of the roof panel 30 and is pressed against the indoor side bent portion 30a of the roof panel 30 in a bent state, and performs a sealing action in the gap between the roof panel 30 and the front window glass 32. At this time, the bent portion of the outer decorative molding portion 345 is shaped like a groove. Further, as described above, the raised portion 346 is pushed toward the outside (upper side) and protrudes toward the front side of the front windshield 32. An upper outer water conduit 36 is defined by the shaped portion. This upper outer side conduit 36 extends in a long shape along the upper bent edge of the roof panel 30, and is used to direct rainwater from the roof panel 30 side to the front windshield 32 side when the car is decelerating. The flow is received by the upper outer water conduit 36, and visibility on the front windshield 32 is maintained well.

Next, the side molding body 35 is continuous from the upper molding body 34 via a corner portion, and has the same cross-sectional structure as the upper molding body 4 except for the raised portion. ing. In FIG. 9, the structure of the side molding body 35 is indicated by reference numeral 3 on the upper side.
4 has been replaced with 35.

This side molding body 35 is provided with a side outer side outer water flow channel 37 which is continuous from the above-mentioned upper outer side water flow channel 36, and a side inner side inner water flow channel 38 defined by a raised portion 356. It is being As shown in FIGS. 9 to 11, the raised portion 356 is formed at an outer side on the upper side near the corner and has a small protrusion from the lower side to the side. It changes gradually towards the top.

More specifically, first, the lower part of the side in FIG.
The raised portion 356 shown on the right end surface is set at the inner molding position closest to the front windshield 32,
Moreover, it is set to have a relatively large amount of protrusion molding height. The molding position and protrusion molding height of the raised portion 356 are maintained the same over a certain section toward the upper side. Thereafter, the molding position of the protruding portion 356 is gradually moved outward, and the height of the protrusion molding is also gradually reduced. At the location near the corner shown in FIG. 11, the molding position of the raised portion 356 has been moved slightly outward, and the amount of protrusion molding height has been significantly reduced. Further, in the upper position shown in FIG. 10, the molding position of the raised portion 356 is moved to the outermost position, and the amount of protrusion molding height is also reduced the most. Then, at the corner portion, the change is made so as to continue to the above-mentioned upper side.

[0033] Due to the gradual change of the protrusion 356,
The side inner water conduit 38 defined between the glass side surface 356a, the front windshield 32, and the inner decorative molding part 353 reduces the groove depth from the lower side to the upper side in the cross section. It is moved toward the outside, and is opened toward the outside of the vehicle just before the corner.

[0034] When the automobile is running, rainwater and the like on the front windshield 32 is sent to the upper side. Therefore, the rainwater, etc. is transferred to the side inner side conduit 38.
It is received by the opponent and moves to the uppercut side. Since the upper end portion of the side inner side water conduit 38 is opened after being displaced toward the outside of the vehicle as described above, rainwater, etc. in the side inner side water conduit 38 flows into the side inner side water conduit 38. It is discharged from the upper end toward a predetermined position outside the vehicle. The discharge destination at this time can be arbitrarily set by appropriately adjusting the molding position displacement and height change of the side inner side water conduit 38.

[0035]

Effects of the Invention As described above, the present invention allows the formation position of the water passage to be continuously changed in the longitudinal direction by extrusion molding of the molded body while changing the formation position of the protruding portion constituting the water passage. Since rainwater, etc. is guided towards a predetermined position where it should be discharged by the guiding action of the headrace whose position has been changed, the headrace can be equipped with a good water guiding function, and the molding function can be improved. can be improved.
