[0009]
[Action]
The gasket for a vehicle window of the present invention includes a window between a vehicle outer side holding portion and an intermediate holding portion in a longitudinal direction by continuously extruding rubber or a synthetic resin into a supply extrusion die while supplying a strip material to the extrusion mold. A molding material having a plate holding groove and having a vehicle body panel holding groove between the intermediate holding portion and the vehicle inner side holding portion is extruded in a state where the strip material is integrated, and at this time, the vehicle outer side holding portion is held. This is obtained by changing the cross-sectional shape of the long material so that the upper portion forms a flush portion in the upper portion and a water receiving portion for blocking the flow of water from the window plate in the side portion. It is manufactured by cutting the formed material into a long material having a length corresponding to one continuous upper part, upper corner part, side part, lower corner part and lower part.
[0010]
In manufacturing the gasket, the flash portion and the water receiving portion of the molding material can be formed by adjusting the shape of the orifice of the extrusion mold in accordance with the extrusion length.
The orifice shape can be adjusted by moving a cutter provided in the orifice and cutting a portion of the extruded long material by a controlled amount along the longitudinal direction. This can be done by moving the movable part of the extrusion mold to change the shape of the orifice. In addition, the flush portion and the water receiving portion can be formed by operating a shaping device provided at a position downstream of the orifice in accordance with the extrusion length.
The molding material is cured by vulcanization in the case of rubber and by cooling in the case of synthetic resin.
[0011]
The gasket manufactured in this manner joins the cut ends together to form a ring, and is attached to the window plate and the vehicle body panel to form a front window of the vehicle. At this time, while guiding by stripping the strip integrated with the gasket, the outer peripheral edge of the window plate is inserted into the window plate holding groove of the gasket, whereby the upper edge of the window plate, the upper corner edge, the side edge, Attach the upper, upper, side, lower, and lower gaskets along the lower and lower corner edges. Similarly, while stripping and guiding the strip, the end portion of the window opening of the vehicle body panel is inserted into the vehicle body panel holding groove of the gasket and attached to the window opening of the vehicle.
[0012]
In this case, when the strip is integrated so that it can be peeled off to the window plate holding groove or the vehicle body panel holding groove, the strip is peeled off to deform the vehicle outer side holding portion or the vehicle inner side holding portion. Therefore, since the window plate or the vehicle body panel is guided to be inserted, the insertion of these becomes easy.
[0013]
In the mounted state, the gasket outer side holding part has a flush part in the upper part, so that the water on the window plate gets over the gasket by the wind pressure during traveling and flows to the roof side, and the air resistance Is small and wind noise is reduced. Since the water receiving part is formed on the side part, rain water on the window plate is prevented from flowing over the gasket and collected or allowed to flow down, or it is guided to near the upper corner part during traveling. Thus, it is possible to prevent the visibility of the side window from deteriorating due to the water droplets flowing laterally to the side window beyond the gasket. Note that whether the water collected in the side portion while preventing lateral flow by the water receiving portion flows down or flows upward along the water receiving portion is determined by the inclination of the vehicle window plate, the traveling speed, and the like. By the way, hereinafter, the term of flowing down also means flowing upward.
At this time, if the water receiving portion has a water collecting groove, the water flows along the water collecting groove, so that the water lateral flow blocking effect is further increased.
Further, when the vehicle outer side holding portion has a water receiving portion in the upper portion, it is possible to keep the visibility of the front window good by blocking the flow of water from the roof panel.
[0014]
  The above gasket has an upper part, upper corner part, side part, lower corner part, and lower part, which have different cross-sectional shapes, and are integrally formed continuously. Appearance is obtained. In the case where the third cross-sectional portion is continuously formed along the longitudinal direction between the first cross-sectional portion and the second cross-sectional portion of the gasket, the first and second cross-section portions are particularly formed as the third cross-sectional portion. One of the cross sections of the other cross section is the other cross sectiongraduallyWhen formed in a changed manner, smooth continuity is maintained between the first and second cross-sections, so that an even better appearance can be obtained.

[0025]
FIG. 5 is a system diagram showing a gasket manufacturing method, FIG. 6 is a side view showing an orifice adjusting device, and FIG.
In the manufacturing method of the gasket 5, first, the strips 19a and 19b are fed out from the bobbins 21a and 21b, and continuously fed into the extrusion mold 23 in a state where they are tensioned to the extent that the brake 22 does not stretch.
[0026]
The extrusion mold 23 is connected to supply rubber or synthetic resin 26a for the main body 5a from the extruder 24 through the resin supply path 25a. The extruder 24 is provided with a motor M <b> 1 that adjusts the resin supply amount according to a command from the control device 27. An extruder for supplying the rubber for the surface layer portion 5b or the synthetic resin 26b is connected to the resin supply path 25b, but the illustration is omitted.
[0027]
An orifice adjusting device 31 that adjusts the shape of the orifice 28 is provided on the outlet side of the extrusion mold 23. In the orifice adjusting device 31, a moving member 34 having a cutter 32 and a discharge path 33 can be moved forward and backward along a guide 35 by a drive screw 36.A clearance angle θ is formed on the back surface of the blade portion of the cutter 32.The drive screw 36 is driven by a motor M <b> 2 that rotates according to an instruction from the control device 27. Reference numeral 38 denotes an extrusion amount detection device for detecting the extrusion amount of the molding material 40, and a detection signal is sent to the control device 27.
[0028]
The extrusion molding material 40 is formed by supplying rubber or synthetic resins 26a and 26b to the extrusion mold 23 and extruding the extrusion mold 23. At this time, the extrusion amount of the molding material 40 is detected by the extrusion amount detection device 38, the motor M2 is driven by a signal from the control device 27, and the cutter 32 is advanced so as to be at the height of the design portion 11 in FIG. The shape of the orifice 28 is adjusted by retracting and cutting off a part of the resin 26b. The cut portion 26c can be recycled and reused.
[0029]
When adjusting the orifice 28 by moving the cutter 32 as described above, the total resin extrusion amount does not change, that is, the screw rotation speed of the extruder is constant, and the extruder 24 changes to the extrusion die 23. Since the amount of resin supplied per time is constant, there is no temporal change in the extrusion pressure of the resin, and stable extrusion can be performed. When the extrusion pressure changes as in the case of adjusting the opening degree of the orifice 28 by vibrating the movable mold of the extrusion mold 23, the motor M1 is controlled by a signal from the control device 27 and the extrusion amount of the extruder 24 is controlled. By adjusting, the resin extrusion pressure can be kept constant.
[0030]
As described above, the flash part 17 is formed in the upper part 5U and the lower part 5L, the water receiving part 18 is formed in the side part 5S, and the upper and lower corner parts 5C.₁5C₂Thus, the molding material 40 whose shape changes is formed, and curing is performed by the curing device 41. The curing device 41 cures the molding material 40 by vulcanizing the rubber and cooling the synthetic resin.
[0031]
The cured molding material 40 is taken up by a take-up machine 42, the take-up quantity is detected by a take-up quantity detection device 43, and cut by a cutting machine 44 driven by a command from the control device 27 based on the signal to form the gasket 5. Is done. The cutting by the cutting machine 44 is performed at an intermediate point of 5L in FIG. 3B, that is, 5K, whereby a gasket 5 made of a long material having a length L corresponding to one is obtained.
[0032]
The gasket 5 manufactured in this manner joins the cut ends 5K to form an annular shape as shown in FIG. 3A, and then attaches to the window plate 4 to form the front window 6 of the vehicle. In addition, it attaches to the protrusion flange 2b of the vehicle body panel 1 after that in the assembly process of a vehicle. At this time, as shown in FIGS. 4 (a) and 4 (b), the vehicle is held outside the vehicle so that the window plate holding groove 14 is expanded while being guided by pulling and peeling the strip 19a integrated with the gasket 5. The outer peripheral edge of the window plate 4 is inserted into the window plate holding groove 14 of the gasket 5 by elastically deforming the portion 12, whereby the upper edge 4U and the upper corner edge 4C of the window plate 4 are inserted.₁Side edge 4S, lower corner edge 4C₂And the upper portion 5U and the upper corner portion 5C of the gasket 5 along the lower edge 4L₁Side part 5S, lower corner part 5C₂And attach the lower part 5L. Similarly, in the vehicle body assembling process, while the strip 19b is peeled and guided, the protruding flange 2b of the vehicle body panel 1 is inserted into the vehicle body panel holding groove 16 of the gasket 5 and attached to the window opening 3 of the vehicle.
[0033]
In this case, since the strips 19a and 19b are integrated with the window plate holding groove 14 or the vehicle body panel holding groove 16 in a peelable state, the strips 19a and 19b are pulled and peeled in a direction intersecting the holding groove. Accordingly, the vehicle outer side holding portion 12 or the vehicle inner side holding portion 15 is deformed so as to be turned, and the insertion of the window plate 4 or the projecting flange 2b of the vehicle body panel 1 is guided.
[0034]
In the mounted state, the outer side holding portion 12 of the gasket 5 is formed with the flush portion 17 in the upper portion 5U, so that the lateral flow of water on the window plate 4 is allowed, the air resistance is small, and wind noise is also generated. Less. Since the water receiving portion 18 is formed in the side portion 5S, the lateral flow of water is prevented, and the rainwater 8 on the window plate 4 is collected and guided or flows down, so that water droplets pass over the gasket 5 to the side window. Deterioration of the visibility of the side window due to the lateral flow can be prevented.
If the water receiving part 18 has the water collecting groove 18a at this time, since the water flows through the water collecting groove 18a, the water blocking effect is further increased.
[0035]
The gasket 5 includes an upper portion 5U and an upper corner portion 5C having different cross-sectional shapes.₁Side part 5S, lower corner part 5C₂Since the lower portion 5L is continuously and integrally formed, there is no sense of incongruity and an excellent appearance can be obtained.
[0036]
8A and 8B show another embodiment, in which FIG. 8A is a UU cross-sectional view of FIG. 1 and FIG. 8B is a SS cross-sectional view. In this embodiment, the water receiving portion 18 in the side portion 5S of the gasket 5 is formed by a ridge 45 that protrudes from the design portion 11. The protrusion 45 is deformed so as to overlap the vehicle outer side holding portion 12 in the upper portion 5U to form a flash portion 17.
[0037]
Such a gasket 5 is formed by extruding in an extrusion mold with the protrusion 45 protruding as shown in FIG. 8B, and then a shaping device installed at the downstream position of the orifice according to the extrusion length. By operating, the protrusion 45 is deformed to form the flash part 17 and the water receiving part 18.
The gasket 5 is attached and used in the same manner as in the previous embodiment.
[0038]
FIG. 9A is a cross-sectional view taken along the line U-U of FIG. 1 showing still another embodiment, and FIG. 9B is a cross-sectional view taken along the line SS. In this embodiment, the water receiving portion 18 is formed on the side of the window plate 4 by the ridge 45 in the side portion 5S as in FIG. 8, but in the upper portion 5U, the ridge 45 is inclined toward the vehicle body panel 1 side. The water receiving portion 18b is formed on the vehicle body panel 1 side, and the outer surface side of the protrusion 45 is the flash portion 17.
[0039]
This gasket 5 is also manufactured by deforming the ridge 45 by a shaping device after extrusion, as in the case of FIG. The actions and effects in the side portion 5S during use are the same as those in FIG. 8, but in the upper portion 5U, the rain water 8 on the vehicle body panel 1 (roof panel 1a) is blocked by the water receiving portion 18b, and the vehicle brakes. Even when applied, it is prevented from flowing down on the window plate 4 and obstructing the field of view.
[0040]
FIG. 10 is a cross-sectional view taken along the line S-S in FIG. 1 showing a gasket according to another embodiment. In this embodiment, the gasket 5 is an example in which a water collecting groove 18 a is formed at the base of the protrusion 46. 46 a is a free state of the ridge 46, and when the gasket 5 is attached to the vehicle body panel 1, the ridge 46 is deformed to a solid line position to form the water collecting groove 18 a.
In use, the rainwater 8 is dammed by the water receiving portion 18 and flows down the water collecting groove 18a, so that the rainwater blocking effect is enhanced.
[0041]
In the above-described embodiment, the combination of the cross-sectional shapes of the upper part and the side part in the gasket 5 in each figure is arbitrary, for example, the upper part in FIG. 2 (a) and FIGS. 8 (b) and 9 (b). Alternatively, a gasket by a combination with the side part of FIG. 10 or a combination of the side part of FIG. 2B and the upper part of FIG. 9A is also possible.
