[0005]

By the way, a glass run channel attached to a window frame of an automobile or the like is used in an environment where a temperature change is large. For example, depending on the location where the vehicle is used, the vehicle may be placed in a high temperature state of about 60 to 80 ° C and / or a low temperature state of about -10 to -30 ° C. For this reason, the vehicle glass run channel is required to have durability such that the shape and physical properties thereof are unlikely to change even when exposed to a large temperature change.

Conventional elastomeric glass run channels have room for improvement in terms of such durability. That is, the conventional glass run channel made of elastomer is relatively easy to expand and contract, and when used for a long time in an environment where the temperature change is large after mounting the window frame, the glass run channel may be displaced from the predetermined mounting position or may be dislocated (hereinafter referred to as " It is collectively referred to as "positional deviation".) There was a risk of a situation.
When such a positional shift becomes remarkable, the glass run channels 112, 11 are
The corner portions of the corner joint members 113 and 1
There may be a state in which the fifteen is bent inward toward the opening 102e side of the window frame 102 (a so-called curl). Occurrence of such a “roll” is not preferable because it not only impairs the aesthetic appearance but also impairs the normal movement of the window glass.

[0007] Conventionally, in order to prevent the occurrence of problems due to such positional displacement, the adhesion of the glass run channel to the window frame is strengthened, or a double-sided adhesive tape or an adhesive is used together and attached to the window frame. It was However, the above-mentioned means is not preferable because it deteriorates the mountability of the glass run channel on the window frame, lowers the work efficiency, and increases the cost.

The present invention was created in order to solve the above-mentioned problems in the conventional elastomer glass run channel, and the purpose of the present invention is to displace the position for a long period of time even in a use environment where the temperature changes greatly. It is an object of the present invention to provide a glass run channel made of an elastomer which does not cause a decrease in work efficiency and does not reduce work efficiency during mounting, and a glass run channel assembly including such a glass run channel.

[0009]

Means, Actions, and Effects for Solving the Problems The present invention provides the glass run channels listed below. That is, the invention of claim 1 has a long body glass mainly formed of an elastomer, which has a long body portion attached to a window frame of a vehicle and forming a groove into which an edge portion of the window glass can fit. It is a run channel. In the main body portion, a reinforced resin molding portion mainly composed of a thermoplastic resin and containing a fibrous reinforcing material and / or a powdery reinforcing material is formed in the longitudinal direction. The reinforced resin molding portion is configured to have a linear expansion coefficient smaller than that of the portion formed mainly of the elastomer, and preferably has a larger elastic modulus.

In this glass run channel, a reinforced resin molded portion having a linear expansion coefficient smaller than that of the main body made of an elastomer is formed in the main body in the longitudinal direction.
Expansion and contraction of the glass run channel main body in the longitudinal direction is limited by the existence of the reinforced resin molding portion. The “linear expansion coefficient” here can be typically calculated by the following method. [Measurement method of linear expansion coefficient] (1) Cut a long test piece into a length of 1000 mm at room temperature (25 ° C). (2) The test piece is freely expanded and contracted and set in a groove-shaped jig. (3) The length of the test piece is measured at −30 ° C. (left standing for 3 hours or more). The measurement result is “1000-α (mm)”. (4) The length of the test piece is measured at + 80 ° C. (left standing for 3 hours or more). The measurement result is “1000 + β (mm)”. (5) The following calculation formula: linear expansion coefficient = (α + β) mm / (10
00 mm × 110 ° C.) to calculate the linear expansion coefficient. Here, "110"
Is the temperature difference (° C.) between the measurements of (3) and (4).

It Alternatively, the base portion or the side wall portion of the main body portion may be substantially the entire reinforced resin molding portion. Further, the size and shape (for example, the cross-sectional shape) of the reinforced resin molding portion are not particularly limited, and may have any shape as long as the desired operation and effect can be obtained.
For example, a sheet or ribbon (plate) shape extending in the longitudinal direction and a non-sheet shape having a polygonal or circular cross section are suitable as the reinforced resin molding portion. The formation position, shape and size of the reinforced resin molding portion may be constant before and after in the longitudinal direction of the glass run channel, or may differ depending on the location.

The glass run channel of the present invention can be easily manufactured by adopting the same molding method as that conventionally used for manufacturing glass run channels for automobiles and various moldings. Typically, a glass run channel having a desired shape (cross-sectional shape) is produced by performing general extrusion molding using an elastomer material or another resin molding material for forming the main body portion and the reinforced resin molding portion. can do. For example, when a resin molding material containing a fibrous reinforcing material is extrusion-molded, the fibers tend to be oriented in the longitudinal direction. As a result, deformation (expansion and contraction) due to stress in the longitudinal direction can be suppressed. Further, the linear expansion of the entire glass run channel can be suppressed.

As an example, a resin material for forming a reinforced resin molding portion (a resin material mainly composed of polypropylene resin or other thermoplastic resin and containing a predetermined amount of fibrous reinforcing material and / or powdery reinforcing material) ) To the extrusion die,
An elongated molded body having a predetermined cross-sectional shape is extruded from the resin material. By this extrusion molding, a long reinforced resin molded body corresponding to the reinforced resin molded portion according to the present invention is molded in advance. Next, as shown in FIG. 3, the long reinforced resin molded body 70 is wound around a drum 71 or the like, and the long reinforced resin molded body 70 is continuously supplied from the drum 71 to an extrusion die 72, and a glass run is performed. An elastomer-forming material (olefin-based thermoplastic elastomer-forming material or the like) 73 for forming the main body of the channel is supplied to the extrusion die 72 in a heated and molten state from a supply port (not shown). Then, together with the elongated reinforced resin molded body 70, the elastomer forming material 7
3 is discharged from the extrusion die 72, and a glass run channel 74 having a predetermined cross-sectional shape is extruded. During this extrusion molding, the surface portion of the long-sized reinforced resin molded body (reinforced resin molded portion) 70 is melted by heat, and the reinforced resin molded portion and the main body made of a predetermined elastomer are integrated by heat welding. A glass run channel 74 is formed. After the extruded glass run channel 74 is cooled by the cooling device 75, it is taken through the take-up device 77 and cut by the cutting device 76.
The glass run channel 74 having a desired length can be obtained by cutting at. This manufacturing method is used when there is a large difference in molding temperature between the reinforced resin molding part and the other resin molding part (main body part) made of elastomer, or when both resins (reinforced resin molding part and main body part) are incompatible. It is preferably adopted. If the compatibility is not good or poor, the surface of the long reinforced resin molded body 70 supplied to the extrusion die 72 to be fixed to the main body can be coated with an adhesive in advance. This can improve the adhesiveness between the long reinforced resin molded portion and the main body made of elastomer.

In the above manufacturing method, the long reinforced resin molded body (reinforced resin molded portion) 7 extruded in advance is used.
0 was wound around a drum 71 and used, but a first extrusion die for molding a long reinforced resin molding and a second extrusion die for molding a glass run channel body were arranged in series. Alternatively, the long reinforced resin molded body molded by the first extrusion die may be continuously supplied to the second extrusion die as it is. In this case,
It is not necessary to store the long reinforced resin molding.

Alternatively, when the molding temperatures of both resins are substantially the same and compatible with each other, so-called two-color extrusion molding (coextrusion molding) is carried out so that the main body and the reinforced resin molding are integrated in the longitudinal direction. The glass run channel can be produced by An example thereof is shown in FIG.
The extrusion die 82 has a first supply port 81a in which a resin material 80 for forming a reinforced resin molding portion is put into a hopper and heated in a cylinder of an extrusion molding machine to be supplied in a molten state,
The elastomer forming material 83 for forming the main body of the glass run channel is similarly provided with the second supply port 81b which is heated and supplied in a molten state. The materials 80 and 83 are respectively supplied from these supply ports, and these materials are extruded from an extrusion port having a predetermined shape (not shown). As a result, the glass run channel 84 in which the reinforced resin molding portion and the body portion made of an elastomer are heat-welded and integrated in one extrusion die 82 is extruded.

Further, the glass run channel assembly including the glass run channel according to the present invention can be manufactured by the same method as the conventional assembly. Typically, predetermined corner joint members are formed by injection molding at the ends of the long glass run channels that are manufactured in advance by extrusion molding or the like. That is, the longitudinal ends of the glass run channels are arranged in a cavity of a mold for molding a predetermined corner joint member with a predetermined gap (cavity), and a predetermined molding material is injected into the cavity. As a result, a corner joint member having a desired shape is formed in a state of being connected to each end of the glass run channel. Since the injection molding method itself does not characterize the present invention, detailed description thereof will be omitted.

As shown in FIG. 6, the glass run channel 14 according to the present embodiment has an opening along the longitudinal direction into which an edge portion of an elevating window glass (not shown) can be fitted when attached to the window frame 2 (2c). Body portion 20 forming groove 24
Is a main component. The main body portion 20 has a base portion 21 corresponding to the bottom portion of the groove 24, and a pair of side wall portions 2 that stand up from both ends of the base portion 21 in the width direction and serve as side walls of the groove 24.
2, 23 (that is, the side wall portion 22 near the vehicle interior and the side wall portion 23 near the vehicle exterior). On the outer surfaces of the side wall portions 22 and 23, a retaining lip 28 that is hooked on the inner surface side of the window frame to hold the glass run channel 14 in a glass run channel mounting groove (not shown) provided on the window frame side.
b and 28c and shielding lips 28a and 28d for covering the edge of the window frame (not shown) are provided. Further, at the free ends of the side walls 22 and 23, the edges of the window glass are provided with grooves 24.
Seal lips 26 and 27 are formed in the longitudinal direction so as to be in close contact with the window glass and prevent water from entering the inside of the vehicle when fitted into the vehicle. The glass run channel body 2

A part (ie, an elastomer constituent part) molded from the part.

As shown in FIG. 6, a sheet (thin plate) shaped reinforced resin molding portion 25 is integrally formed in the longitudinal direction on the groove inner surface of the base portion 21 of the glass run channel 14. The reinforced resin molding part 25 has 40 parts by weight of the olefinic thermoplastic elastomer molding material, 40 parts of ultra-high molecular weight polyethylene, and polypropylene resin 1 in a weight ratio.
5 parts and PAN-based carbon fiber (“Besfight (trademark) HTA-C6-N” manufactured by Toho Rayon Co., Ltd., fiber length 6)
mm, average fiber diameter 7 μm) 2.5 parts (including other auxiliary components 2.5 parts). That is, the carbon fiber (fibrous reinforcing material) content of the reinforced resin molding portion according to this example is in the range of 2 to 3 mass% (about 2.5 mass%).

The glass run channel 14 according to this embodiment.
Can be easily manufactured by coextrusion as illustrated in FIG. 3 above. That is, the main body molding material (the olefinic thermoplastic elastomer molding material) and the reinforced resin molding material (the carbon fiber-containing material) are supplied from different extruders to one extrusion die, Extrusion molding is performed from the extrusion port having the cross-sectional shape shown in FIG. As a result, the extruded body molding material and the reinforced resin molding material are welded and joined in the longitudinal direction,
It is possible to easily manufacture the glass run channel according to the present embodiment in which the main body portion 20 and the reinforced resin molding portion 25 are integrated.

In the glass run channel 14 according to this embodiment, the reinforced resin molding portion 25 is formed inside the groove of the base portion 21.
Since the base is formed, the mechanical strength (in particular, elastic modulus and rigidity corresponding thereto) of the base portion 21 (and thus the main body portion 20) can be kept high. Further, it is possible to suppress the occurrence of positional displacement due to the edge portion of the window glass that has entered the groove 24 coming into contact with the inside of the groove (typically the surface of the reinforced resin molding portion) of the glass run channel body portion 20. You can Further, since the reinforced resin molding portion 25 is formed in the base portion 21 in a sheet shape, the reinforced resin molding portion 25 can be mounted while freely bending in the sheet thickness direction (that is, the mounting direction of the glass run channel to the window frame). Therefore, a curved portion 2e (FIG. 5) between the inclined portion 2b and the horizontal portion 2c of the window frame 2 in the up-down direction (the same direction as the window frame mounting direction of the glass run channel).
It can be mounted correctly in the specified mounting position by following the above procedure. Further, the reinforced resin molding portion 25 according to the present embodiment is excellent in low friction property as a result of containing the ultrahigh molecular weight polyethylene in a relatively high rate. Therefore, the slidability of the window glass that contacts the glass run channel 14 is improved. Therefore, in the glass run channel at the position where the window glass slides (for example, the glass run channels indicated by reference numerals 12 and 16), the smooth movement (elevation) is realized, and the positional deviation of the glass run channel due to the movement of the window glass is realized. Can be prevented.

Next, the glass run channel according to this example was exposed to an environment accompanied by a large temperature change, and the stretch resistance was examined. That is, a glass run channel according to this example having a total length of 1000 mm was attached to a predetermined automobile door panel window frame, and the entire door panel was housed in a constant temperature test chamber. Then, (i) .- 30 ° C for 4 hours, (ii) .Normal temperature (25 ° C) for 1 hour, (iii) .80 ° C for 4 hours, and (iv) .Normal temperature (25 ° C).
The thermal cycle of (i) to (iv) consisting of 1 hour was repeated 3 times (10 hours × 3 times = total 30 hours). After the completion of the temperature change test by the cooling / heating cycle, the glass run channel attached to the window frame was removed and the entire length thereof was measured. The results are shown in Table 1. A glass run channel having the same raw material composition and shape as that of this example except that the portion corresponding to the reinforced resin molding is also made of the same material as that of the main body is extruded by the same manufacturing method (one-color extrusion molding using two extruders). It was manufactured under the conditions, and the same temperature change test was conducted at the same time as the above. The results are shown in Table 1 as a reference example.

[0051]

[Table 1]

As is clear from Table 1, as compared with the reference example, the glass run channel according to this example hardly contracted even after being exposed to a large temperature change due to the above temperature cycle, and the glass run channel at the beginning of molding It kept almost the entire length. From this, it was confirmed that the glass run channel according to this example has a high degree of stretch resistance. In addition, when each of the separate glass run channels identical to those of the example and the reference example was left in a natural state and the state was confirmed by hand at a high temperature of 80 ° C., the reference example softened and easily bent. In contrast, the example remained relatively rigid. From this, it was confirmed that the example maintained a higher elastic modulus than the reference example, especially at high temperature. Further, in the glass run channel according to the present example (similarly to the examples described later), as a result of the reinforced resin molding portion having a low linear expansion coefficient including the fibrous reinforcing material (and / or the powdery reinforcing material), the thermoplastic resin It has higher elongation resistance and shrinkage resistance than the glass run channel body made of elastomer. Therefore, for example, even when a tensile force is applied when the glass run channel is attached to the window frame, no distortion occurs. Further, since the high-rigidity reinforced resin molded portion is formed in the longitudinal direction, when a physical force from the outside (for example, a compressive force in the glass run channel longitudinal direction accompanying the up and down movement of the window glass) is applied, It is possible to prevent the glass run channel main body from contracting or extending by the reinforced resin molded portion serving as a support portion capable of withstanding the physical external force.

Next, glass run channels in which a reinforced resin molding portion having the same composition as that of the first embodiment is formed in different portions of the base will be described as a second embodiment and a third embodiment. still,
The glass run channels 14A and 14B according to the second embodiment and the third embodiment have the same outer shape and structure as the first embodiment except the formation position of the reinforced resin molding portion. The same glass run channel assembly 10 (see FIG. 5) having excellent stretch resistance can be manufactured.

In the glass run channel 14A shown in FIG. 7 as the second embodiment, the reinforced resin molding portion 25A has the base portion 20.
It is characterized in that it is formed on the outer surface side of A, that is, on the outer surface of the groove 24. According to this configuration, the reinforced resin molding portion 25
As a result of A being formed on the outer side of the base portion 21A, that is, on the side of the window frame mounting surface, the mechanical strength and rigidity of the base portion 21A can be improved without impairing the appearance (aesthetics). Further, since the reinforced resin molding portion 25A is provided in a portion where the window glass cannot contact, it is not necessary to provide the reinforced resin molding portion 25A with a low friction property (slippery for realizing high sliding of the window glass). . Further, various desired accessories can be provided inside the groove 24 without being restricted by the presence of the reinforced resin molding portion 25A. For example, in a glass run channel (for example, a glass run channel attached to the window frames 2a and 2d) at a position corresponding to the edge of the window glass moving in the groove, a resin molded portion (that is, a glass run channel attached to the window frames 2a and 2d) having a low friction property (that is, Glass sliding layer) groove 24
The glass run channel (for example, the window frame 2) that can be laminated and formed on the inner surface of the
In the glass run channel attached to c), a collision noise preventing device can be formed in the groove.

In the glass run channel 14B shown in FIG. 8 as the third embodiment, the reinforced resin molding portion 25B has the base portion 20.
It is characterized in that it is embedded inside B. According to this configuration, as a result of the reinforced resin molding portion 25B being embedded inside the base portion 21B, it is possible to improve the mechanical strength and rigidity of the base portion 21B without impairing the appearance (aesthetic appearance) as in the second embodiment. You can In addition, since the reinforced resin molding portion 25B is provided at a portion where the window glass cannot come into contact with the reinforced resin molding portion 25B, it is not necessary to provide the reinforced resin molding portion 25B with low frictional property (slippery for realizing high sliding of the window glass). . Accordingly, various desired accessories (for example, the glass sliding layer and the collision noise generation preventing device) can be provided inside or outside the groove 24 without being restricted by the existence of the reinforced resin molding portion 25B. Also,
As a result of embedding the reinforced resin molded part 25B, the reinforced resin molded part 25B and the base part 21B are excellent in unity, and even if the glass run channel 14B is strongly curved, the reinforced resin molded part is peeled off. Can be prevented.
