Abstract
Description
Technical Field
[0001] The present invention relates to a glass slide provided on a car door and having an extension portion with a decorative film provided on the outer side of the car, an installation structure of the glass slide, and a method for manufacturing the glass slide. Background Technology
[0002] In the past, such as Figure 11 as well as Figure 12 As shown, it is known that there are structures in which glass channels 10 and 20 with decorative films F are installed on the frames 3 and 4 of automobile doors 1 and 2 (front door 1 and rear door 2) (see, for example, Patent Document 1). Furthermore, in Figure 12 The injection molding part is indicated by a slash.
[0003] In the glass slide 10 installed on the front door 1, the decorative film F is provided on the outer side of the decorative lip 12 provided on the outer side of the installation part 11 of the glass slide 10. In particular, at the upper corner of the front door 1, the decorative lip 12 is formed to extend further to the rear side from the upper rear end. The decorative film F is also continuously provided on the outer side of the extended setting part 13.
[0004] Similarly, in the glass slide 20 installed on the rear door 2, the decorative film F is provided on the outer side of the decorative lip 22 provided on the outer side of the glass slide 20 mounting part. In particular, at the upper corner of the rear door 2, the decorative lip 22 is formed to extend further forward from the upper front end, and the decorative film F is also continuously provided on the outer side of the extended setting part 23.
[0005] At the dividing point between the front door 1 and the rear door 2, glass tracks 10 and 20 are installed with their extensions 13 and 23 facing each other.
[0006] Thus, the window frame trim between front door 1 and rear door 2 achieves a sense of continuity, enhancing the overall appearance.
[0007] However, the cross-sectional shapes of the extended portions 13 and 23 of the glass slides 10 and 20 are as follows: Figure 13 As shown, after the decorative film F is extruded together with the extrusion molding material, the end faces 13a and 23a of the extension parts 13 and 23 are supplemented by injection molding material.
[0008] Here, the end Fa of the decorative film F is also positioned at the same location as the end faces 13a and 23a of the extension portions 13 and 23. Additionally, in Figure 13 For ease of illustration, the decorative film F is painted black, but in actual products, the decorative film F is generally set to a color other than black.
[0009] Therefore, since the face-to-face ends of the glass grooves 10 and 20, which are extensions, are exposed by the black supplementary molding parts 14 and 24, when the front door 1 and the rear door 2 are closed, two black stripes caused by the supplementary molding parts 14 and 24 are generated between the front door 1 and the rear door 2 when viewed from the outside, resulting in poor aesthetics.
[0010] On the other hand, there is also a known structure where the supplementary molding parts 14 and 24 are not provided, and an end cap (not shown) is embedded in the end face of the extension part of the glass groove (for example, see Patent Document 2). In this case, stripes are formed between the end cap and the mating surface, which hinders the continuity of the decorative film F and results in poor aesthetics.

[0017] The decorative film (F) is configured such that it bends from the outer side of the extension portion (53, 73) to the inner side of the vehicle at the end of the extension portion (53, 73) to cover the end face (53c, 73c) of the extension portion (53, 73).
[0018] Furthermore, a feature of the present invention is that the upper end (F1) and lower end (F2) of the decorative film (F) are inclined from the outside of the vehicle to the inside of the vehicle or are arc-shaped.
[0019] The present invention is characterized in that the upper end (F1) and lower end (F2) of the decorative film (F) are formed by cutting off the decorative film side from a certain distance (FL1, FL2) from the end face (53a, 73a) of the extended setting portion (53, 73) to form a decorative film side cut-off portion (FK1, FK2), thereby reducing the width (FW1, FW2) of the remaining portion of the decorative film (F) in the vertical direction.
[0020] In addition, the present invention is characterized in that the upper end (F1) and the lower end (F2) of the decorative film (F) are chamfered on the opposite side of the end face (53a, 73a) of the extended setting portion (53, 73) to the side of the decorative film (F) side cut-out portion (FK1, FK2) so as to bend the corner (FK1a, FK2a).
[0021] Furthermore, the present invention is characterized in that the decorative film (F) is provided on the extension portion (53, 73) via a base member (90) of a hard resin that is harder than the material constituting the extension portion (53, 73), and at the end of the extension portion (53, 73), it bends together with the base member (90) from the outside of the vehicle to the inside of the vehicle, covering the end face (53c, 73c) of the extension portion (53, 73).
[0022] In addition, the present invention is characterized in that an insert plate (91) is embedded between the bent base member (90) and the end faces (53c, 73c) of the extended portion (53, 73).
[0023] Furthermore, the installation structure of the glass slide of the present invention is characterized in that the glass slides (50, 70) are respectively installed on the front door (1) and the rear door (2). On the front door (1) side, the extension part (53) of the glass slide (50) extends from the rear end of the upper part of the front door (1) to the rear side, and on the rear door (2) side, the extension part (73) of the glass slide (70) extends from the front end of the upper part of the rear door (2) to the front side. The extension parts (53, 73) are provided opposite to each other at the dividing part between the front door (1) and the rear door (2).
[0024] Furthermore, the manufacturing method of the glass slide of the present invention includes a mounting portion (51, 71) mounted on the frame (3, 4) of a car door (1, 2), a main body portion (52, 72) for guiding the raised and lowered door glass (G) in the slide portion, and an extension portion (53, 73) extending from the upper edge of the car door (1, 2) toward a side away from the car door (1, 2) and provided with a decorative film (F).
[0025] The decorative film (F) is configured such that it is disposed on the extension portions (53, 73) via a base member (90) of a hard resin that is harder than the material constituting the extension portions (53, 73), and at the ends of the extension portions (53, 73), it bends together with the base member (90) from the outside of the vehicle to the inside of the vehicle, covering the end faces (53c, 73c) of the extension portions (53, 73). Its characteristic is that...
[0026] For the extended setting portion (53, 73), after the decorative film (F) and the base member (90) are extruded together, a cut (M1) is made by cutting a certain distance (L) parallel to the decorative film (F) from the end face (53a, 73a) of the extended setting portion (53, 73), and a cut (M2) is made by cutting a certain distance (J) from the inside of the vehicle to the outside of the vehicle, thereby removing a portion of the extended setting portion (53, 73). After removing the removed portion (K), the remaining portion (Z) is bent towards the inside of the vehicle at any position. Then, injection molding is performed in a manner that covers the end face (Za) of the bent remaining portion (Z).
[0027] Furthermore, the manufacturing method of the glass slide of the present invention includes a mounting portion (51, 71) mounted on the frame (3, 4) of a car door (1, 2), a main body portion (52, 72) for guiding the raised and lowered door glass (G) in the slide portion, and an extension portion (53, 73) extending from the upper edge of the car door (1, 2) toward a side away from the car door (1, 2) and provided with a decorative film (F).
[0028] The decorative film (F) is configured such that it is disposed on the extension portions (53, 73) via a base member (90) of a hard resin that is harder than the material constituting the extension portions (53, 73), and at the ends of the extension portions (53, 73), it bends together with the base member (90) from the outside of the vehicle to the inside of the vehicle, covering the end faces (53c, 73c) of the extension portions (53, 73). Its characteristic is that...
[0029] For the extended setting parts (53, 73), after the decorative film (F) and the base member (90) are extruded together, a cut (M1) is made by cutting a certain distance (L) parallel to the decorative film (F) from the end face (53a, 73a) of the extended setting parts (53, 73), and a cut (M2) is made by cutting a certain distance (J) from the inside of the vehicle to the outside of the vehicle, thereby removing a portion of the extended setting parts (53, 73). After removing the removed portion (K), the remaining portion (Z) is bent towards the inside of the vehicle by a bending distance (S = LT) obtained by subtracting the non-bending distance (T) from the certain distance (L). Then, injection molding is performed in a manner that covers the end face (Za) of the bent remaining portion (Z).
[0030] Furthermore, the manufacturing method of the glass slide of the present invention includes a mounting portion (51, 71) mounted on the frame (3, 4) of a car door (1, 2), a main body portion (52, 72) for guiding the raised and lowered door glass (G) in the slide portion, and an extension portion (53, 73) extending from the upper edge of the car door (1, 2) toward a side away from the car door (1, 2) and provided with a decorative film (F).
[0031] The decorative film (F) is configured such that it is disposed on the extension portions (53, 73) via a base member (90) of a hard resin that is harder than the material constituting the extension portions (53, 73), and at the ends of the extension portions (53, 73), it bends together with the base member (90) from the outside of the vehicle to the inside of the vehicle, covering the end faces (53c, 73c) of the extension portions (53, 73). Its characteristic is that...
[0032] The upper end (F1) and lower end (F2) of the decorative film (F) are inclined from the outside of the vehicle to the inside of the vehicle or are arc-shaped.
[0033] Regarding the extended mounting portions (53, 73), after the decorative film (F) and the base member (90) are extruded together, a cut (M1) is made by cutting a certain distance (L) parallel to the decorative film (F) from the end face (53a, 73a) of the extended mounting portion (53, 73), and a cut (M2) is made by cutting a certain distance (J) from the inside of the vehicle to the outside of the vehicle, thereby removing a portion of the extended mounting portion (53, 73). After removing the removed portion (K),
[0034] For the upper end (F1) and lower end (F2) of the decorative film (F), a decorative film side cut-off portion (FK1, FK2) is formed by cutting off the decorative film side from a certain distance (FL1, FL2) from the end face (53a, 73a) of the extended setting portion (53, 73), thereby reducing the width (FW1, FW2) of the remaining portion in the vertical direction.
[0035] The remaining portions (FZ1, FZ2) after removing the decorative film (F) side cut-out portions (FK1, FK2) are bent inwards by a bending distance (S), and then injection molded in a manner that covers the end faces (FZ1a, FZ2a) of the bent remaining portions (FZ1, FZ2).
[0036] In addition, the present invention is characterized in that the upper end (F1) and the lower end (F2) of the decorative film (F) are chamfered (FK1, FK2) on the side opposite to the end face (53a, 73a) of the extended part (53, 73) in such a way that the corner is bent.
[0037] In addition, the reference numerals in parentheses indicate the corresponding elements or items described in the drawings and the embodiments described below.
[0038] According to the present invention, since the decorative film provided on the outer side of the extended portion of the glass channel is configured such that it bends from the outer side of the extended portion to the inner side of the vehicle at its end, covering the end face of the extended portion, the decorative film is exposed on the surface. In particular, products based on the present invention can be manufactured at a lower cost and are lighter in weight compared to products with metal decorative strips.
[0039] As a result, the extended sections of the glass tracks installed on the front and rear doors are positioned opposite each other at the boundary between the front and rear doors, resulting in a high degree of continuity between the decorative film installed on the front door side and the decorative film installed on the rear door side, and a good aesthetic appearance.
[0040] In other words, it will not be like the past ( Figure 13 As shown in the diagram, two black stripes are generated at the end of the extended section, caused by a supplementary molding section formed by injection molding material.
[0041] Furthermore, in automobiles, the area of the center pillar opposite the front and rear doors is located at eye level, making it more visually noticeable than other parts, thus enhancing the effectiveness of this invention.
[0042] Furthermore, according to the present invention, since the upper end and lower end of the decorative film are inclined or arc-shaped from the outside of the vehicle to the inside of the vehicle, the upper end and lower end of the decorative film are formed by cutting off the decorative film side from a certain distance (L) from the end face of the extension setting portion, thereby reducing the width of the remaining portion of the decorative film in the vertical direction. Therefore, when the end of the extension setting portion bends from the outside of the vehicle to the inside of the vehicle, it is possible to prevent the formation of a sharp point or wrinkle at the bending position.
[0043] Furthermore, since the upper and lower ends of the decorative film are chamfered on the side opposite to the end face of the extended part to bend the corner, it is possible to further prevent the formation of sharp points or wrinkles.
[0044] Furthermore, according to the present invention, since the decorative film is disposed on the extension portion via a base member made of a hard resin that is harder than the material constituting the extension portion, the decorative film is stably supported on the base member. Therefore, even if the decorative film itself is very thin, it can be easily bent from the outside of the vehicle to the inside of the vehicle together with the base member at the end of the extension portion, and can be configured to cover the end face of the extension portion.
[0045] Furthermore, according to the present invention, since an insert plate is embedded between the bent base member and the end face of the extension part, the base member with the decorative film can be easily supported and fixed in the mold when supplementary molding is performed using injection molding material.
[0046] Furthermore, according to the present invention, since the decorative film and the base member are extruded together for the extended setting portion during the manufacture of the glass groove, a cut (M1) is made by cutting a certain distance (L) parallel to the end face of the extended setting portion, and a cut (M2) is made by cutting a certain distance (J) from the inside of the vehicle to the outside of the vehicle, thereby removing a portion of the extended setting portion, and after removing the removed portion (K), the remaining portion (Z) is bent towards the inside of the vehicle at any position. Therefore, compared with the case where the decorative film and the base member are separately attached to the end of the extended setting portion after extrusion, the extended setting portion, the decorative film and the base member can be integrated to improve the tight contact.
[0047] Furthermore, according to the present invention, since the bending distance (S = LT) obtained by subtracting the non-bending distance (T) from the certain distance (L) to bend the remaining part (Z) towards the inside of the vehicle is obtained, and then injection molding is performed in a manner that covers the end face (Za) of the bent remaining part (Z), even if there is a deviation in the shape of the cut-off part, the injection molding material fills the gap and the processing can be perfectly completed.
[0048] Furthermore, according to the present invention, since the upper and lower ends of the decorative film are inclined from the outside of the vehicle to the inside of the vehicle or are arc-shaped, after a portion of the extended setting portion is cut off, the decorative film side is also cut off from the end face of the extended setting portion at a certain distance (FL1, FL2) for the upper and lower ends of the decorative film, reducing the width of the remaining portion in the vertical direction. After removing the cut portion of the decorative film side, the remaining portion is bent towards the inside of the vehicle by a bending distance (S). Then, injection molding is performed in a manner that covers the end face of the bent remaining portion. Therefore, when bending the remaining portion from the outside of the vehicle to the inside of the vehicle, it is possible to prevent the formation of a sharp point or wrinkle at the bending position of the decorative film.
[0049] Furthermore, since the upper and lower ends of the decorative film are chamfered on the side opposite to the end face of the extended part, the corners are bent, thus further preventing the formation of sharp points or wrinkles. Attached Figure Description

[0132] Reference Figures 1 to 6A ~ Figure 6D as well as Figure 10 The glass slide according to an embodiment of the present invention will be described. Furthermore, the same reference numerals are used for parts that are identical to those shown in the conventional examples. Additionally, in Figure 1 The injection molding section is indicated by a diagonal line. Additionally, in... Figures 1 to 6A ~ Figure 6D The decorative film F is marked in black.
[0133] The glass slide 50 of the embodiments of the present invention is as follows: Figure 1 , Figure 2 , Figure 3 as well as Figure 10 As shown, a concealed glass slide is installed on the flange 3A extending along the outer side of the car door, specifically the front door 1, in a manner that covers the frame 3 from the outside of the car.
[0134] The glass channel 50 is formed by connecting two extruded components, one on the roof side and the other on the center pillar side (not shown), at the corner of the upper rear end side of the front door 1 via an injection molding part Mo. It has a mounting part 51 mounted on the flange 3A and a main body part 52 that guides the raised and lowered door glass G within the channel.
[0135] The outer side of the mounting section 51 is an extension section 53 extending from the upper rear end of the front door 1 toward the side away from the front door 1, that is, toward the rear of the car when the front door 1 is closed. A decorative film (here, a glossy film) F is provided on the outer side of the extension section 53 via a base member 90. Here, decorative pieces 81 and 82 are installed on the outer side of the front door 1 and the rear door 2, respectively, on the center pillar side.
[0136] like Figure 2 As shown, the mounting portion 51 has a roughly U-shaped cross-section. The mounting portion 51 includes an upper sidewall portion 55 extending in the inward / outward direction, a lower sidewall portion 56, and a connecting wall portion 57 connecting the upper sidewall portion 55 and the lower sidewall portion 56. An engaging and fixing portion 58 is formed on the inner side, which elastically contacts the flange 3A. Here, three lip-shaped engaging and fixing portions 58 are formed on the lower part of the upper sidewall portion 55, and two protruding engaging and fixing portions 58 are formed on the upper part of the lower sidewall portion 56.
[0137] A body sealing lip 59 protrudes from the upper part of the upper sidewall 55 at approximately the center, elastically contacting the periphery of the body opening (not shown) to seal the body between the body and the front door 1. Additionally, a sealing lip 60 protrudes from the inner end of the upper sidewall 55, extending downwards towards the inner side and elastically contacting the flange 3A, and a lip 61 extends upwards towards the outer side. Furthermore, a covering lip 62 protrudes from the upper outer surface of the upper sidewall 55, connecting to and covering the decorative film F installed on the outer side of the glass channel 50. Additionally, a core material 63 with a generally U-shaped cross-section is embedded along the upper sidewall 55, connecting wall 57, and lower sidewall 56, thereby improving rigidity.
[0138] The main body 52 includes the aforementioned lower sidewall portion 56 that guides the raised and lowered door glass G in a groove, an inner sidewall portion 64 and an outer sidewall portion 65 extending downward from the inner and outer sides of the lower sidewall portion 56. The outer sidewall portion 65 is continuously provided with the connecting wall portion 57. The portion where the outer sidewall portion 65 and the connecting wall portion 57 are joined together extends towards the rear of the vehicle when the front door 1 is closed, forming an extension portion 53 (e.g., ...). Figure 10 (As shown).
[0139] An inner lip 66 is provided on the outer side of the end of the inner side wall portion 64, extending outward and slidingly contacting the inner side of the door glass G. An outer lip 67 is provided on the inner side of the end of the outer side wall portion 65, extending inward and slidingly contacting the outer side of the door glass G. Additionally, a glass sealing lip 68 protrudes below the lower side wall portion 56, elastically contacting the end of the door glass G, but this can be omitted.
[0140] Here, as Figure 3 As shown, the mounting portion 51 and the main body portion 52 of the extended mounting portion 53 are configured to extend from... Figure 2 The extruded cross-sectional shape of the glass channel 50 shown on the roof side is the extruded cross-sectional shape after the inner side wall portion 64, inner lip portion 66, outer lip portion 67, and glass sealing lip 68 have been removed.
[0141] Although detailed descriptions are omitted, the shape of a portion of the supplementary molding part 54, which will be described later, can be connected to the mounting part 51 or the main body part 52 side by injection molding to form an integral connection.
[0142] Furthermore, although detailed descriptions are omitted, a glass track 70 with the same structure as the glass track 50 installed on the front door 1 is also installed on the rear door 2. The glass tracks 50 and 70 are respectively installed on the frames 3 and 4 of the front door 1 and the rear door 2, such that on the front door 1 side, the extension portion 53 of the glass track 50 extends toward the rear side, which is the side away from the upper rear end of the front door 1, and correspondingly, on the rear door 2 side, the extension portion 73 of the glass track 70 extends toward the front side, which is the side away from the upper front end of the rear door 2. The extension portions 53 and 73 are provided opposite each other at the dividing point between the front door 1 and the rear door 2.
[0143] The glass channels 50 and 70 are made of materials such as EPDM (rubber) or TPE (thermoplastic elastomer) such as TPO or TPS, and can be made of sponge or solid materials. In this case, they are made of solid TPE materials.
[0144] In addition, the base member 90 is made of a hard resin that is harder than the material of the extended parts 53 and 73 constituting the glass grooves 50 and 70, and its thickness is 2 mm or less (preferably 1 mm or less). Its flexural modulus is higher than that of the glass grooves 50 and 70, and it is made of a material in the range of 850 to 4500 MPa.
[0145] The base member 90 is made of, for example, a material in which talc or glass fiber is mixed into polypropylene. The flexural modulus can be adjusted by varying the amount of talc or glass fiber incorporated to achieve the aforementioned range. The material of the base member 90 is not particularly limited as long as it falls within the aforementioned range; other materials may also be used.
[0146] Decorative film F such as Figure 2 as well as Figure 3 As shown, its upper end F1 and lower end F2 bend from the outside of the car towards the inside in an inclined or arc shape (alternatively, it can also be the following shape: the upper end F1 and lower end F2 of the decorative film F do not bend, but extend straight up and down). Furthermore, with Figure 3 Different, such as Figure 20 As shown, the upper end F1 and lower end F2 of the decorative film F can also be bent into an arc shape, and the extruded material can be used to cover a portion of both ends of the decorative film F.
[0147] In addition, such as Figure 4 as well as Figure 5 As shown, at the ends of the extension parts 53 and 73, they are configured to bend at a right angle from the outside of the vehicle to the inside of the vehicle together with the base member 90, covering the end faces 53c and 73c of the extension parts 53 and 73.
[0148] The base member 90 with the decorative film F, which is bent, is supplemented by supplementary molding parts 54 and 74 made of injection molding material between the end faces 53c and 73c produced by the removal of the extended parts 53 and 73. Figure 4 In order to facilitate the understanding of positional relationships, the intermediate core N used in injection molding using a mold is also recorded.
[0149] Additionally, as a decorative film F, examples include thin films or film materials with an adhesive or bonding layer on the back side of the appearance design layer.
[0150] Examples include stainless steel films, metal vapor-deposited films, synthetic resin laminated films, films with decorative patterns on the surface, and films colored in the desired color.
[0151] The adhesive layer or bonding layer can be any layer that has adhesive properties to the base member 90, or it can have a primer layer between the layer and the base member 90.
[0152] Glass channels 50 and 70 are two components extruded and formed on the roof side and the center pillar side as described above. They are connected via injection molding parts Mo at the upper rear corner of the front door 1 and the upper front corner of the rear door 2, respectively, and thus extend into extension parts 53 and 73. The manufacturing method is described in [reference needed]. Figures 6A to 6D Please provide an explanation.
[0153] First, the base component 90 and the decorative film F are extruded together with the mounting parts 51, 71 and the main body parts 52, 72. Figure 6A ).
[0154] Then, at a certain distance (L) from the end, the member is cut off using a cutter or rotary cutter, etc., so as to remove a portion of the extended part 53, 73 in a manner that at least the decorative film F and the base member 90 are preserved. Figure 6B ).
[0155] Furthermore, more specifically, firstly, in Figure 6A In the middle, a cut M1 is made by cutting a certain distance (L) from the ends 53a and 73a of the extended setting part 53 and 73 parallel to the decorative film F, and a cut M2 is made by cutting a certain distance (J) from the inside of the vehicle to the outside of the vehicle.
[0156] Next, as Figure 6B As shown, the cut-off portion K, which is part of the extension setting portion 53, 73, can be easily removed through the cut M1 and cut M2.
[0157] Here, through cut M1, side surfaces 53b and 73b, created by cutting, are formed in the extension portion 53; through cut M2, end surfaces 53c and 73c, created by cutting, are formed in the extension portion 53. Furthermore, either cut M1 or cut M2 can be made first, or they can be made simultaneously, but it is preferred to make cut M1 first. Additionally, at this time, cut M1 may only retain the decorative film F and the base member 90, but... Figure 3 As shown, when the wall thickness of the base member 90 is thin, or when the boundary line between the base member 90 and the connecting wall portion 57 and the outer side wall portion 65 is not straight but curved, the cut M1 can be cut out in such a way that a part of the connecting wall portion 57 or the outer side wall portion 65 is retained together with the base member 90 in the extended setting portion 53.
[0158] Even though the decorative film F is very thin, it is supported in a stable state by the base member 90 at the ends 53a and 73a of the extension parts 53 and 73, so it is easy to cut off only a part of the extension parts 53 and 73.
[0159] like Figure 6B , Figure 6C , Figure 6D As shown, the remaining portion (Z) consisting of the decorative film F retained after removing the cut-off portion K from the extended setting portion 53, 73 and the base member 90 is bent towards the inside of the vehicle by a bending distance (S). The bending distance (S) is the bending distance obtained by subtracting the non-bending distance (T) from a certain distance (L) (S = LT).
[0160] Since the decorative film F is supported in a stable state by the base member 90, even a thin decorative film F can be easily bent from the outside of the vehicle to the inside of the vehicle together with the base member 90.
[0161] At this time, the decorative film F and the base member 90 bend inward toward the vehicle with respect to a point P located below the base member 90 at a distance (S) from the end face 90a of the base member 90.
[0162] Here, as Figure 6C As shown, an incision M3 is made on the base member 90 from the side 53b created by the excision, extending upwards and outwards to point P, as... Figure 6D As shown, the cut M3 is blocked during bending, but the cut M3 can be a triangular recess, a line, or no cut M3 at all. Alternatively, the remaining portion (Z) consisting of the decorative film F retained after removing the cut portion K from the extended setting portions 53 and 73 and the base member 90 can be bent inwards at any position of the retained remaining portion (Z).
[0163] Alternatively, the M3 cut can also be replaced as follows: Figure 19A As shown, the recessed part M4 is a quadrilateral shape formed using a cutting tool or heating plate, etc., and can also be... Figure 19B As shown, the quadrilateral recess M5 is obtained by removing a portion up to a part of the base member 90 using a tool or heating plate. Alternatively, it can be obtained as follows: Figure 19C As shown, the quadrilateral recess M6 is obtained after removing the base component 90 by using a tool or the like, and the non-bending distance is 0.
[0164] After that, as Figure 5 as well as Figures 6A to 6D As shown, the end (Za) of the decorative film F and the remaining part of the base member 90 that can cover the bending is injection molded with respect to the range (R) of the end face 53c, 73c produced by cutting of the mounting part 51, 71 of the extension part 53, 73 or the main part 52, 72, and supplementary molding parts 54, 74 are formed by injection molding material.
[0165] Therefore, even if there is a deviation in the shape of the cut-off part K, the injection molding material will fill the gap, thus enabling perfect processing.
[0166] Here, the supplementary molding parts 54 and 74 are formed in such a way that they become one with the surface of the bent decorative film F, so that when the car doors 1 and 2 are viewed from the outside of the car, the black supplementary molding parts 54 and 74 will not be visible.
[0167] According to the glass channels 50 and 70 configured in this way, the decorative film F provided on the outer side of the extended installation portions 53 and 73 of the glass channels 50 and 70 is configured such that at the end of the extended installation portions 53 and 73, it bends from the outer side of the extended installation portions 53 and 73 towards the inner side of the vehicle, covering the end faces 53c and 57c of the extended installation portions 53 and 73, so that the decorative film F is exposed on the surface.
[0168] Therefore, at the boundary between the front door 1 and the rear door 2, the decorative film F installed on the front door 1 side and the decorative film F installed on the rear door 2 side have a high degree of continuity and good aesthetic appearance.
[0169] In addition, the decorative film F, in particular, can produce the same appearance at a lower cost and is lighter than products with metal decorative strips.
[0170] In addition, in this embodiment, such as Figure 5 as well as Figures 6A to 6D As shown, at least the decorative film F and the base member 90 are bent at a right angle from the outside of the vehicle to the inside, but it can also be as follows: Figure 7As shown, the decorative film F and the base member 90 are bent into an acute angle relative to a right angle, that is, folded back forward on the front door 1 side and folded back backward on the rear door 2 side. Then, injection molding is performed to supplement the molding of the area (R) of the end faces 53c, 73c generated by the cutting, which can cover the remaining bent part and the extension parts 53, 73 that were not cut off (remaining after cutting off).
[0171] At this time, the supplementary molding parts 54 and 74 are not on the same surface as the decorative film F, but because the bent decorative film F and the base member 90 are held by the injection molding material, the close contact with the injection molding material is high, which improves the bonding strength.
[0172] In this embodiment, the injection molding material flows into the area (R) that covers the bent decorative film F, the base member 90, and the end faces 53c and 73c created by cutting off the extended portions 53 and 73. However, it is also possible to... Figure 8 As shown, a rectangular insert plate 91 is inserted therebetween, and injection molding is performed on the end face (Za) that can cover the remaining bent part, the end faces 53c and 73c of the extension parts 53 and 73 produced by cutting, and the range (R) of the insert plate 91.
[0173] Here, before injection molding using a mold, the insert plate 91 can be bonded as needed to the ends 53c, 73c of the extension parts 53, 73 produced by cutting or the bent portion of the remaining part (Z) of the base member 90 to form an integral part.
[0174] Alternatively, at this time, the decorative film F and the base member 90, which are bent and held together by the insert plate 91, can be covered from the outside by using injection molding material to form the supplementary molding parts 54 and 74.
[0175] Therefore, since the injection molding is performed on the area that covers the lower end of the insert plate 91, the bent decorative film F, and the base member 90 after the insert plate 91 is inserted, the base member 90 with the decorative film F can be easily supported and fixed in the mold (not shown) used during injection molding, and the shape accuracy of the injection-molded part can also be improved. Furthermore, although the figure is omitted, the area of the insert plate 91 can be set to be smaller than the area of the bent decorative film F and the bent part of the base member 90, thereby increasing the bonding area between the base member 90 and the supplementary molding parts 54 and 74 and further improving the bonding strength.
[0176] Furthermore, alternative uses in Figure 8 The insert plate 91 shown can also be used as follows: Figure 9As shown, the intermediate core N of the mold is used for direct support to injection mold supplementary molding parts 54 and 74.
[0177] In addition, in this embodiment, such as Figure 6B As shown, after removing the cut-off portion K, which is part of the extension installation portions 53 and 73, using cuts M1 and M2, the remaining portion (Z) is bent inwards to obtain the bending distance (S = LT) by subtracting the non-bending distance (T) from a certain distance (L). However, after removing the cut-off portion K, further as... Figure 15 As shown, it is also possible to remove the trimmed portion FK1 from the upper end F1 and lower end F2 of the decorative film F, and then bend the remaining portion (FZ1) towards the inside of the vehicle.
[0178] This is because, since the upper end F1 and lower end F2 of the decorative film F are respectively bent from the outside of the vehicle to the inside into an inclined or arc-shaped extruded cross-section, when the remaining part (Z) of the extended installation parts 53 and 73 is bent from the outside of the vehicle to the inside, due to the difference in circumference, there is no space for wall thickness to be removed on the inner part of the bend. Figure 14 As shown, there are cases where pointed V-shapes or wrinkles are formed, and as... Figure 15 That's how it's shown, to prevent this from happening.
[0179] Therefore, as Figure 6B As shown, after a portion (cut-off portion K) of the extension mounting portions 53 and 73 is cut off, as Figure 15 As shown, for the upper end F1 and lower end F2 of the decorative film F, a certain distance FL1 is cut off from the end faces 53a and 73a of the extended parts 53 and 73, reducing the width FW1 of the remaining portion in the vertical direction. Regarding the decorative film side cut-off portion FK1 at this time, in... Figure 15 The middle part is represented by a slash.
[0180] After that, according to Figure 15 When the dotted line X1 bends the remaining portion (FZ1) of the extended mounting parts 53 and 73 from the outside of the vehicle to the inside, it becomes... Figure 16 As shown, when the injection molding material is further used to form the supplementary molding parts 54 and 74, it becomes Figure 17 As shown.
[0181] Additionally, here, the bend line X1 slopes forward from top to bottom, but this can be changed to match the car's exterior design. For example, in the case of a glass slide installed at the upper rear end of the front door or at the upper front end of the rear door, it can also slope forward to match the exterior design. Figure 15 Tilt in the same direction.
[0182] Alternatively, it can be designed to complement the car's exterior without tilting.
[0183] In addition, such as Figure 6C As shown, a triangular recess or a linear cutout M3 can be provided for the base member 90 extending upwards and outwards to point P, or it can be omitted.
[0184] In addition, alternative Figure 6C , Figure 6D The cut M3 shown can also be set. Figure 19A , Figure 19B , Figure 19C The cuts shown are M4, M5, and M6.
[0185] In addition, such as Figure 15 As shown, when cutting off the decorative film F-side cut-off portion FK1, a chamfer FK1a is obtained by chamfering the side of the decorative film F-side cut-off portion FK1 opposite to the end faces 53a and 73a of the extension portions 53 and 73 in a manner that makes the corner bend, thereby further preventing the formation of sharp V or wrinkles.
[0186] Alternatively, the starting position of the chamfer FK1a can be near the point where the cut portion FK1 on the F side of the decorative film intersects with the bend line X1, or it can be at the point where the cut portion FK1 on the F side of the decorative film intersects with the bend line X1.
[0187] In addition, in order to minimize the cutting of the decorative film F-side cut-out portion FK1 when the open portion is formed by bending the remaining portion (FZ1) of the extension setting portion 53, 73, shaping based on thermo-compression molding can also be performed at the same time.
[0188] In addition, alternative Figure 15 The decorative film side cut-off portion FK1 shown can also be Figure 18 The decorative film side excision portion FK2 is shown.
[0189] Furthermore, such as Figure 15 , Figure 18 As shown, the bending lines X1 and X2 are preferably set near the curvature radius R cutoff of the chamfers FK1a and FK2a. If they extend beyond the curvature radius R cutoff, and are further away from the straight section, the size of the black injection-molded material portion of the supplementary molding portions 54 and 74 embedded in the chamfers FK1a and FK2a will be larger when viewed from the outside of the vehicle, resulting in a worse vehicle appearance, which is not preferable. Conversely, if the portion does not extend beyond the curvature radius R cutoff but is further away from it, the walls will overlap more during bending, resulting in larger V-shaped tips or wrinkles, a worse product appearance of the glass groove, which is also not preferable.
[0190] Furthermore, compared to the decorative film F-side cut-out portion FK1, the decorative film F-side cut-out portion FK2 is configured such that the upper and lower ends are closer to the center side as it approaches the end face of the decorative film. Also, the width FW2 of the remaining portion of the decorative film in the vertical direction is smaller than the width FW1, and the cut-out distance FL2 is set to be smaller than the cut-out distance FL1. A chamfer FK2a is obtained by beveling the side of the decorative film F-side cut-out portion FK2 opposite to the end faces 53a and 73a of the extension portions 53 and 73, by bending the corner. The chamfer FK2a is set to be smaller than the chamfer FK1a. By configuring the decorative film F-side cut-out portion FK2 in this way, the chamfer FK2a is set to be smaller than the chamfer FK1a.
[0191] Alternatively, the starting position of the chamfer FK2a can be near the intersection of the cut portion FK2 on the F side of the decorative film and the bend line X2, or it can be at the intersection of the cut portion FK2 on the F side of the decorative film and the bend line X2.
[0192] like Figure 16 as well as Figure 17 As shown, since the black injection molding material portion that conceals the chamfer FK1a as a supplementary molding portion 54, 74 is smaller when viewed from the outside of the vehicle, the appearance of the vehicle is further improved. Furthermore, since the remaining width FW2 of the decorative film F is set to be smaller than the width FW1, the degree of wall overlap is smaller when bending the decorative film F, and the tip V or wrinkles are smaller, further improving the product appearance of the glass groove.
[0193] In this embodiment, after the base member 90 and the decorative film F are extruded together with the mounting parts 51, 71 and the main body parts 52, 72, a portion of the extension parts 53, 73 is cut off. Alternatively, the structure obtained by extruding the connecting wall parts 55, 57 of the glass grooves 50, 70 and the outer side wall part 65 of the vehicle without setting the base member 90 can be bonded to the extruded part on the center pillar side via the injection molding part Mo. Then, the separate decorative film F is pasted on the outer side of the glass grooves 50, 70. After the end faces 53a, 73a of the extension parts 53, 73 are supplemented and molded using injection molding material, the ends are bent from the outer side of the vehicle to the inner side of the vehicle to cover the ends of the extension parts 53, 73 that are supplemented and molded using injection molding material.
[0194] Furthermore, in this embodiment, the case where a decorative film F is installed on a concealed type of extended mounting portion 53, 73 that is installed in a manner that covers the frames 3, 4 of the front door 1 and the rear door 2 from the outside of the vehicle is described, but as shown in the conventional examples ( Figure 12It can also be used when the mounting part 11 is inserted into the frame from below, and when the decorative film F is installed on the extension parts 13 and 23 of the decorative lips 12 and 22 provided on the outside of the vehicle.
[0195] In addition, in this embodiment, such as Figure 5 , Figure 10 As shown, the description focuses on the portion where the extension part 53 of the front door 1 and the extension part 73 of the rear door 2 are provided opposite each other at the dividing point. However, it can also be applied to portions where there are no extension parts facing each other, such as the injection molding part on the front side of the front door 1 or the injection molding part on the rear side of the rear door 2.
[0196] In addition, in this embodiment, such as Figure 5 , Figure 10 The description is for the case where the extension part 53 of the front door 1 or the extension part 73 of the rear door 2 protrudes further to the dividing part than the extruded part on the center pillar side, but it can also be applied to the case where it does not protrude but only reaches the position of the extruded part on the pillar side.
