The third lip portion 16 protrudes along the tip of the other wall 11d.
[0016]
The support lip 12 can be constituted by using the same kind of members constituting the first to third lip portions 14 to 16, preferably 70 ° HsA (Shore A hardness) or less synthetic resin, particularly preferably soft. Polyvinyl chloride resin, olefin elastomer (thermoplastic elastomer (TPO)) and the like are used. Alternatively, the outer surface portion may be 70 ° HsA (Shore A hardness) or less, and a metal core material or a synthetic resin core material of 100 ° HsA (Shore A hardness) or more may be embedded. The support lip 12 projects from the inner surface of the other wall 11d of the main portion 11a (the surface facing the one wall 11c) to the tip along the longitudinal direction of the outside molding body 11. At the front end portion 11b where one wall 11c is cut out, the support lip 12 and the third lip portion 16 are exposed in a single state when the outside molding 10 is viewed from the room.
[0017]
The support lip 12 separates the other wall 11d from the one wall 11c when the other wall 11d of the high-rigidity portion 13 is pressed toward the one wall 11c in the main portion 11a of the outside molding body 11. When the outside molding 10 is assembled to the door panel and the vehicle user or the like leans on the vehicle or leans by hand, the other wall 11d feels toward the one wall 11c. This is to prevent an unnatural fall feeling.
[0018]
The tip of the support lip 12 is fused to the resin on the support lip 12 and the outside molding body 11 side at the notched tip 11b of the outside molding body 11, and the support lip 12 is attached to the tip of the support lip 12 A notched fixing portion 17 formed by pressing so as to spread toward the edge of the portion 11b is formed. As will be described later, the fixing portion 17 heats the support lip end portion 44 using a condensing heating device, so that the members constituting the support lip 12 are melted earlier, and then the outside molding main body 11 is It can be formed by heating so that the high-rigidity portion 13 to be melted and pressing the tip. The material melting temperature of the support lip 12 and the high-rigidity portion 13 is preferably selected so that the high-rigidity portion 13 is higher than the support lip 12.
[0019]
By forming the fixing portion 17, the support lip end portion 44 has a bag shape, and this portion is difficult to move vertically and horizontally. As a result, the trouble of correcting the orientation of the support lip end 44 when the outside molding 10 is assembled to the door panel can be omitted, and the assembling workability can be improved.
Further, the fixing portion 17 is provided on the support lip 12, and the surface of the acute angle portion 18 of the outside molding body 11 is melted and the unevenness is flattened when the fixing portion 17 is formed. Even if it contacts the adjacent glass run 23, each surface is not damaged.
[0020]

As shown in FIG. 2, the outside molding 10 is attached to the door 21 of the automobile 20 at a portion in contact with the door glass 22. Further, reference numeral 23 in FIG. 2 denotes a glass run made of an elastic body such as rubber that supports the door glass 22 so as to be slidable up and down.
[0021]
FIG. 3 is a view showing a waist rear portion of the door 21 (front door). The door 21 is configured by joining a door inner panel 24 and a door outer panel 25 except for the door glass 22 portion.
The door outer panel 25 is formed with a first shelf 26 extending in the horizontal direction and a second shelf 27 extending in the vertical direction. The outside molding 10 is placed on the first shelf 26. The second shelf 27 extends from the door waist portion toward the roof portion. In this assembly structure, a shelf continuous portion 28 that connects the first shelf 26 and the second shelf 27 is provided. Such a structure having the shelf continuous portion 28 is often used for a vehicle having a narrow vehicle width, and by adopting such a structure, it is possible to secure an interior width and a front seat back side space, It can also be said to be a taste. The shelf continuous portion 28 is provided so as to be inclined in the cross section, and the overall length of the outside molding 10 can be shortened.
The door inner panel 24 is provided with a channel 29 that supports the back of the glass run 23.
[0022]
FIG. 4 is a view taken in the direction of arrow A in FIG. In this portion, the glass run 23 is mounted on the second shelf 27 of the door outer panel 25 and the back portion thereof is supported by the channel 29 of the door inner panel 24. The glass run 23 is in contact with the notched tip portion 11 b of the outside molding 10.
FIG. 5 is a sectional view taken along the line SA-SA in FIG. Outsa I The molding 10 is assembled to the first shelf 26 of the door outer panel 25 in a state where the protruding portion of the first shelf 26 is inserted into the pocket of the main portion 11a. In this state, the support lip 12 and the third lip portion 16 are in contact with the first shelf 26. Further, the support lip 12 has the other wall 11d when the other wall 11d of the main portion 11a is pushed toward the one wall 11c (ie, from the outside of the vehicle to the indoor side) (direction 45 toward the vehicle interior). Can be urged in the direction of separating from the one wall 11c.
[0023]
In the mounting structure of the outside molding 10, when the end surface of the outside molding 10 is formed so as to be parallel to the shelf continuous portion 28 being inclined in the cross section, when the outside molding 10 is assembled, the tip of the outside molding 10 is assembled. 4 and the shelf continuous portion 28 become inconspicuous, and the appearance is improved. Therefore, an acute angle portion indicated by reference numeral 18 in FIG. 4 is formed at the tip of the outside molding body 11. In the assembled state, since the acute angle portion 18 is located on the indoor side from the ridge line 28a of the shelf continuous portion 28, it is considered that the finger does not enter in the vehicle state, but care must be taken when replacing parts. The acute angle portion 18 may damage the glass run 23, particularly the glass run visible portion 23a, when the vehicle is assembled, and the glass run is exchanged for an object having no other damage. Further, when the damaged part is in a state where the vehicle is completed and hidden by the outside molding 10, the vehicle becomes as it is. If the glass run 23 slightly shifts when the door glass slides, a scratch hidden by the outside molding of the glass run visible portion 23a may be seen. According to the outside molding 10 of this embodiment, since the surface of the acute angle portion 18 of the outside molding main body 11 is melted and the unevenness is flattened when the fixing portion 17 is formed, the outer surface outer melting portion of the outside molding main body 11 is fixed. Even if 46 touches the glass run 23 at the time of vehicle assembly, the surface thereof is not damaged.
[0024]
FIG. 6 is a diagram for explaining an embodiment of a method for manufacturing an outside molding according to the present invention. In the manufacturing method according to the present embodiment, the front end portion of the support lip 12 and the high-rigidity portion 13 immediately below it are heated using the condensing heating device 30, and then the front end of the heated support lip 12 is pressed to fix the fixed portion. 17 is formed.
[0025]
The condensing heating device 30 used in this manufacturing method mainly includes a lamp (light source) 31 that generates near infrared light having a wavelength of 0.8 μm to 1.5 μm, and reflects the light from the lamp 31 to the focal point 32. And an apparatus main body 34 having a reflecting surface 33 for condensing light. As the lamp 31, a halogen lamp or the like having good near-infrared light emission efficiency is preferably used. Further, a gold plating layer having good infrared reflection efficiency can be provided on the reflection surface 33 of the apparatus main body 34. A holding portion 36 having a fixing hole 35 is formed at the rear end of the apparatus main body 34. The apparatus main body 34 is fixed to a processing apparatus 40 described later using the holding portion 36 and the fixing hole 35. As the condensing heating device 30, a conventionally known device as described in, for example, JP-A-4-42786 can be used.
[0026]
In this condensing heating device 30, the angle θ formed by the straight line connecting the lamp 31 and the focal point 32 and the longitudinal direction of the outside molding 10 is 100 to 160 degrees, preferably 130 to 155 degrees, and most preferably about 145 degrees. Arranged to perform heating. If this angle θ is the above angle, the cut surface at the tip of the outside molding 10, particularly the acute angle portion 18, is appropriately melted, the whitening of the cut surface is corrected, the color and gloss are good, and the irregular reflection is inconspicuous. An excellent cut surface can be formed.
[0027]
FIGS. 7 and 8 show the outside molding 10a before the formation of the fixing portion 17 (FIGS. 7A, 7B, and 8A) and after the formation (FIGS. 7C, 7D, and 7). It is a figure which shows the outside molding 10 of FIG.8 (b)).
The outside molding 10a before the formation of the fixing portion 17 shown in FIGS. 7A, 7B, and 8A includes a high-rigidity portion 13, first to third lip portions 14 to 16, and a support lip. 12 is formed by extrusion molding or the like to form a long molded product, and then cut into a desired length, and a notched tip portion 11b is produced.
[0028]
Since the tip of the support lip 12 is cut together with the high-rigidity portion 13 when cutting a long extruded product as described above, the tip of the cut support lip end 44 is sharpened. In this outside molding 10a, even if the support lip end portion 44 is slightly in contact with the glass run 23, it moves freely from side to side and up and down, and it takes time and effort to turn the support lip end portion 44 in a prescribed direction. Further, the tip of the support lip end 44 is visible from the clearance between the acute angle portion 18 and the shelf continuous portion 28 in the vehicle state, and the appearance is deteriorated. These disadvantages are inevitably caused in order to produce the outside molding 10a by constant cross-section extrusion. Conventionally, in order to reduce these problems, a process of cutting an extra support lip end 44 is added. However, it has been difficult to perform such a process at low cost without damaging other parts.
[0029]
In addition, in the outside molding 10a before the fixing portion 17 shown in FIG. 7A, the cut surface, in particular, the acute angle portion 18 shown in FIG. 7B becomes whitish due to the whitening phenomenon that occurs when the hard resin is cut, There was a problem that the color was clearly different from the design surface. This whitening always occurs when a shearing direction force is applied, degrading the appearance quality of the product.
[0030]
According to the method of the present invention, by forming the fixing portion 17 at the distal end of the support lip end portion 44, it is possible to eliminate all of these problems that have occurred in the outside molding 10a before processing.
As shown in FIG. 6, a heating region in which the fixing portion 17 is to be formed by condensing and irradiating near infrared light mainly having a wavelength of 0.8 to 1.5 μm to the tip of the support lip end 44 of the outside molding 10 The focal point 32 is moved along the (reflected beam focal point irradiation range) to perform local heating. This type of heating method is characterized in that the focal point 32 is rapidly locally heated and the other parts are hardly heated. The heating at the focal point 32 has a fast rise time up to a maximum output of 1200 ° C. (about 5 to 6 seconds), and the heating of the support lip 12 and the high-rigidity portion 13 heated to about 200 to 250 ° C. It can be heated in a short time (about 1 second) and is excellent in productivity.
[0031]
After the support lip end portion 44 is heated, this portion is pressed and spread, and is pressed against the high-rigidity portion 13 of the outside molding body 11. As a result, the tip of the support lip 12 is bonded to the high-rigidity portion 13, and as shown in FIGS. 7C, 7D, and 8B, the tip of the support lip 12 is bonded to the high-rigidity portion 13 in an adhesive manner. Part 17 is formed. The front end of the support lip end 44 is fixed to the high-rigidity portion 13 and is formed into a bag shape to restrict the left / right / up / down movement.
[0032]
Since the fixing portion 17 is provided at the tip of the support lip end 44 in this manner, the tip of the support lip end 44 becomes difficult to move left and right and up and down, and it is troublesome to correct the orientation of the support lip 12 when the outside molding 10 is assembled. This can be omitted and the assembly workability can be improved.
Further, since the surface of the acute angle portion 18 of the outside molding body 11 is melted and the unevenness is flattened when the fixing portion 17 is formed, the outer surface melting portion 46 of the outside molding body 11 contacts the glass run 23 during the vehicle assembly. But it won't damage the surface.
In this manufacturing method, the angle formed by the straight line connecting the light source and the focal point of the condenser heating device 30 and the longitudinal direction of the outside molding 10 is about 145 degrees, and near infrared light having a wavelength of 0.8 μm to 1.5 μm. By heating using, the acute angle portion 18 of the outside molding main body 11 is appropriately melted, whitening is corrected, and a surface excellent in color, gloss, and irregular reflection can be formed.
[0033]
In order to form the fixing portion 17 for limiting the movement of the tip of the support lip end 44 on the outside molding 10a before the fixing portion 17 is formed using the condensing heating device 30 shown in FIG. It is preferable to carry out using the processing apparatus 40 shown in FIG. 9-14 is a figure which shows in order the process of forming the said adhering part 17 in the outside molding 10a shown in Fig.7 (a) obtained by cutting a long molded article.
[0034]
The processing device 40 shown in these drawings includes a lower mold 41 on which at least the notched tip end portion 11b of the outside molding 10a is placed with the support lip 12 facing downward, and is movable up and down above the lower mold 41. Condensation provided so as to be movable between a position where the upper mold 42 provided and the support lip end 44 of the outside molding 10a placed on the lower mold 41 can be focused and a standby position below the position. The heating device 30 is provided. A cutter 43 that cuts off the excess at the tip of the outside molding 10 after pressing is attached to the upper mold 42 so as to be movable in the horizontal direction in the figure.
[0035]
In order to process the outside molding 10a using the processing apparatus 30, first, as shown in FIG. 9, the outside molding 10a produced by cutting a long molded product is used as a lower mold 41 of the processing apparatus 30. As shown in FIG. 10, the outside molding 10a is set on the lower mold 41 with the support lip 12 facing downward. In the state where the outside molding 10a is set on the lower mold 41, the upper mold 42 stands by at the upper and lower upper limit positions, and the condensing heating device 30 is at the lower standby position with respect to the outside molding 10a.
[0036]
Next, as shown in FIG. 11, the condensing heating device 30 is raised from the standby position to a position that focuses on the tip of the support lip end 44 of the outside molding 10 a set on the lower mold 41. The tip of the end 44 is heated locally for a short time. This heating time can be appropriately selected depending on the heating capacity of the condensing heating device 30, the material of the support lip 12, and the like. By using the high performance condensing heating device 30, the tip of the support lip 12 is instantaneously melted at its melting temperature. It is possible to raise the temperature to
[0037]
Next, as shown in FIG. 12, the condensing heating device 30 is lowered to the lower standby position, then the upper die 42 is lowered as shown in FIG. 13, and the outside molding 10a set in the lower die 41 is moved. By pressing, the tip of the support lip end 44 heated to the molten state is pressed against the high-rigidity portion 13 to form the fixing portion 17 where both are fused together.
[0038]
Next, the cutter 43 is moved to the front end side of the outside molding 10 while the upper die 42 is lowered, and the excess wall protruding from the upper and lower dies 41 and 42 is cut. By this series of operations, as shown in FIGS. 7C and 8B, the outside molding 10 in which the fixing portion 17 is formed at the tip of the support lip end 44 is manufactured.
Then, the upper mold | type 42 is raised, the outside molding 10 is taken out, it returns to the state shown in FIG. 9, and the said process is repeated.
