Description

Technical Field

[0001] The present invention relates to an automotive glass catch provided on a glass run that is attached to a door frame of an automobile and guides a door glass, and a method for manufacturing the same.

Background Art

[0002] As shown in FIGS. 15 to 17, glass runs 20 and 30 for guiding a vertically moving door glass 2 are provided on a door frame 10 of an automobile, and glass catches (glass guides) 25 and 35 are provided on the glass runs 20 and 30 to reinforce the glass runs 20 and 30 (see, for example, Patent Documents 1 and 2).

[0003] The glass catch 25 shown in FIG. 16 is attached to the outside of the glass run 20 by inserting a fixing plate portion 26 that protrudes inward from the glass catch 25 into the glass run 20 from the outside of the vehicle. In this way, when the glass catch 25 is separate from the glass run 20, the number of parts increases, and since it is necessary to accurately engage the fixing plate portion 26 with the glass run 20 side, the processing man-hours also increase accordingly. In addition, since a joint portion is formed between the glass run 20 and the glass catch 25, it is necessary to devise a way to make the joint portion less noticeable.

[0004] On the other hand, the glass catch 35 shown in FIG. 17 is integrally formed with the glass run 30, so there is no particular increase in the number of parts or processing man-hours, and the appearance is also good.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the glass catch 35 shown in FIG. 17, the core material 37 is embedded. However, when the glass run 30 and the glass catch 35 are simultaneously molded, it is necessary to fix the core material 37 in the mold and keep its position stable. Although not specifically described in Patent Document 2, for example, when molding with pins standing from the mold and pressing the tips against the surface of the core material 37, the glass run 30 will have an outer surface with holes at the parts where the pins are pressed, and the surface of the core material 37 will be partially exposed, resulting in a poor appearance.

[0017] Further, the present invention is characterized in that third protrusions (105a, 105b) are formed on the second mold (102) which contact the lower side vehicle interior side surface of the resin member (70) attached to the insert panel (60).

[0018] Note that the symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the embodiments for carrying out the invention described later.

Effect of the Invention

[0019] The glass catch for an automobile door of the present invention is integrally molded with a glass run with a stainless steel insert panel embedded as a core material, so the number of processing steps can be reduced compared with a separate object, and the appearance is also good. Further, since the entire circumference of the insert panel is completely covered by the resin member, the metal surface of the insert panel is not exposed to the outside and inside of the vehicle. According to this, since the insert panel is covered with the resin member, there is no concern about rust and the rigidity is also improved. At this time, although the surface of the resin member is exposed, the exposed amount can be reduced by attaching a decorative mold to the outside of the vehicle, and the appearance is not significantly deteriorated by making the exposed part the same color as the color of the molded layer.

[0020] Also, when integrally molding the glass catch for automotive doors with the glass run, when setting the insert panel to be embedded between the first mold and the second mold, the upper part on the outside of the vehicle of the resin member is brought into contact with the inner surface of the first mold, and the upper part on the inside of the vehicle of the resin member is brought into contact with the inner surface of the second mold and set in this state, so that the position of the insert panel can be stabilized, and it is possible to easily manufacture a glass catch for automotive doors with a shape and size as intended by pouring the molding material.

[0021] Also, in the case where the inner side surface of the insert panel is exposed without being covered with the resin member, the amount of the resin member can be reduced, and the inner side surface of the exposed insert panel can be used for positioning.

[0022] Further, according to the present invention, since a protruding connecting portion that extends inward from the upper end portion of the insert panel and is integrally formed with the inner side wall portion of the glass run is formed in the resin member, the resin member has an L-shaped cross section, and when integrally molding the glass catch for automotive doors with the glass run, the insert panel covered with the resin member by the mold can be stably supported from the inside and outside of the vehicle.

[0023] Further, according to the present invention, since an upper through hole is formed in the upper part of the insert panel, it is also possible to support the insert panel locally covered with the resin member by inserting a protrusion (second protrusion) formed in the mold (second mold).

[0024] Further, according to the present invention, since an annular fitting portion that penetrates from the outside of the vehicle to the upper through hole is formed in the resin member, the upper through hole is blocked and the metal surface of the insert panel is not exposed to the inside of the vehicle. And since a recess that opens inward is formed in the central portion of the annular fitting portion, it is also possible to support the insert panel locally covered with the resin member by inserting a protrusion (second protrusion) formed in the mold (second mold) into this recess.

[0025] Further, according to the present invention, the second mold is formed with a third protrusion that abuts against the lower side inner surface of the vehicle of the resin member attached to the insert panel. Therefore, the lower part of the insert panel covered with the resin member is supported by being sandwiched from the outside and inside of the vehicle by the first mold and the second mold, and the movement of the insert panel can be restricted and stably supported when flowing the molding material.

Mode for Carrying Out the Invention

[0027] With reference to FIGS. 1 to 8 and FIG. 15, an automobile door glass catch and its manufacturing method according to an embodiment of the present invention will be described. The same parts as those shown in the conventional example are denoted by the same reference numerals.

[0028] As shown in FIGS. 1 to 3 and FIG. 15, the glass catch 100 for an automobile door according to an embodiment of the present invention is attached to a part (here, the front side of the upper side) of a frame body 10 provided on a door 1 of an automobile, and is molded so as to partially expand and protrude downward with respect to the outside of the vehicle of a glass run 40 that guides a vertically moving door glass 2 in a groove portion, and a core material 60 is embedded inside. Note that, as shown in FIG. 2, FIG. 1 shows a state where a decorative molding (such as a light molding) 80 attached to the outside of the vehicle is removed. The X-X line and Y-Y line shown in FIG. 1 correspond to the positions shown by the A-A line and B-B line in FIG. 15.

[0029] As shown in FIG. 4, this glass run 40 is formed by extrusion molding and is of a hidden type that is attached along the outside of the vehicle of the frame body 10 and covers and hides a part of the frame body 10 from the outside of the vehicle. As shown in FIG. 3, the automotive door glass catch 100 is formed by partially notching the extruded glass run 40 and molding it in the notched part.

[0030] As shown in FIG. 4, the glass run 40 has an attachment portion 41 attached to the flange 10F extending outward of the vehicle in the frame body 10 from the outside of the vehicle, and a main body portion 42 that forms a groove portion on the inside and guides the vertically moving door glass 2 in the groove portion.

[0031] The attachment portion 41 has a substantially U-shaped cross-section formed by an upper wall portion 43 extending in the vehicle interior and exterior direction, a bottom wall portion 44, and a connecting wall portion 45 connecting the upper wall portion 43 and the bottom wall portion 44. Two locking portions 46 and a lip portion 47 that elastically contact the flange 10F are formed inward. On the upper surface of the substantially central portion of the upper wall portion 43, a body seal lip portion 48 that elastically contacts the periphery of the vehicle body opening and seals between the body and the door 1 protrudes.

[0032] The main body portion 42 is composed of the above-described bottom wall portion 44 that guides the vertically moving door glass 2 in the groove portion, an inner side wall portion 51 provided from the inside and outside of the vehicle of the bottom wall portion 44, and an outer side wall portion 52. On the outer side surface of the end of the inner side wall portion 51 of the vehicle, an inner side seal lip portion 53 is provided which extends outwardly of the vehicle and is in sliding contact with the inner side surface of the door glass 2. Also, on the inner side surface of the end of the outer side wall portion 52 of the vehicle, an outer side seal lip portion 54 is provided which extends inwardly of the vehicle and is in sliding contact with the outer side surface of the door glass 2. Further, on the inner side surface of the end of the inner side wall portion 51 of the vehicle, a molding lip portion 55 is provided which extends inwardly of the vehicle. Note that a seal lip which elastically contacts the end of the door glass 2 can also be provided protruding downward of the bottom wall portion 44. The connecting wall portion 45 of the mounting portion 41 and the outer side wall portion 52 of the main body portion 42 are vertically continuous, and a decorative molding 80 is attached to the outer side thereof. Note that FIGS. 3 and 4 show a state in which the decorative molding 80 is omitted.

[0033] As shown in FIG. 5, the core material 60 is a substantially flat plate-shaped insert panel 60 made of stainless steel (SUS) and extends vertically along the shape of the outer side wall portion 52 of the vehicle, and is embedded in the outer side wall portion 52 of the vehicle. Further, through holes 61a, 61b, 61c, 61d are formed at the four corners of the insert panel 60. Note that the number of through holes in the insert panel 60 may be further increased in order to strengthen the adhesive force between the insert panel 60 and the resin member 70.

[0034] As shown in FIGS. 6 and 7, a resin member 70 that covers the entire circumference of the insert panel 60 is attached to the insert panel 60 so that the insert panel 60 is not exposed. The resin member 70 has a substantially rectangular covering portion 71 that covers the insert panel 60, a support portion 72 that extends in the front-rear direction of the door 1 from the upper portion of the covering portion 71 along which the glass run 40 extends, and a protruding connecting portion 73 that extends inwardly from the upper end portion of the support portion, and the longitudinal cross-sectional shape is an L shape. The assembly of the insert panel 60 and the covering portion 71 of the resin member 70 is not particularly limited, and it is sufficient that the entire insert panel 60 is embedded in the resin member 70 so as not to be exposed. Here, a cut 74 is provided at the upper part of the resin member 70, and with the lower end 75 of the resin member 70 as a fulcrum, the upper part opens outward and inward from the cut 74 like the arrows in FIG. 7. When opened, after the insert panel 60 is placed in the recess 76 formed in the resin member 70, it is closed and the cut 74 is sealed with a connecting agent so that the insert panel 60 is sandwiched by the resin member 70 from both the outside and inside of the vehicle. At this time, the protruding portions 75a, 75b, 75c, 75d provided at the four corners of the resin member 70 are respectively inserted into the through holes 61a, 61b, 61c, 61d formed in the insert panel 60, thereby being positioned and stably assembled.

[0035] As the resin member 70, it is desirable to use a lightweight and strong one. Here, talc polypropylene is used, but it is not particularly limited. Also, for the color of the resin member 70, the same color as the later-described mold forming layer M1 is used so that the boundary portion with the mold forming layer M1 is not conspicuous.

[0036] As shown in FIG. 3, in the portion of the glass run 40 where the automotive door glass catch 100 is provided, the mounting portion 41 excluding the bottom wall portion 44 of the glass run 40 is extrusion-molded, and the other parts, that is, the main body portion 42 of the glass run 40 integrally formed with the automotive door glass catch 100, is mold-formed. The entire insert panel 60 is covered by the resin member 70. The upper part of the outer surface of the resin member 70 is exposed, and a mold forming layer M1 is provided on the surface of the resin member 70 to cover the lower part of the outer surface and the lower end part to the inner surface of the vehicle. Also, the protruding connecting portion 73 of the resin member 70 extends inward from the upper end of the insert panel 60 to form the bottom wall portion 44 of the mounting portion 41 of the glass run 40, and an inner side wall portion 51 is integrally mold-formed with the inner side seal lip portion 53 at the tip thereof. Further, the molded layer M1 extends so as to form the inner side surface of the outer side wall portion 52 of the glass run 40 up to the lower part of the approximate center of the protruding connecting portion 71 including the outer side seal lip portion 54. As a result, the bottom wall portion 44 of the mounting portion 41 of the glass run 40 is formed such that the inner side is the protruding connecting portion 73, and the outer side is formed by overlapping the protruding connecting portion 73 and the molded layer M1, making it thick.

[0037] The automotive door glass catch 100 configured as described above is manufactured as follows. First, a predetermined length is cut out from the main body portion 42 (including the bottom wall portion 44) of the extruded glass run 40 and the lower half of the connecting wall portion 45 of the mounting portion 41 in the longitudinal direction in which the glass run 40 extends. The remaining portion of the mounting portion 41 is sandwiched between a first mold 101 and a second mold 102 as shown in FIG. 8.

[0038] Next, an insert panel 60 with a resin member 70 mounted so as to be entirely covered is placed between the first mold 101 and the second mold 102. The upper part of the resin member 70 on the outer side of the vehicle is brought into contact with the inner surface of the first mold 101, and the upper part of the resin member 70 on the inner side of the vehicle is brought into contact with the inner surface of the second mold 102. Further, a part of the lower surface of the protruding connecting portion 73, that is, the inner side of the vehicle, is set in a state of being in contact with a first protrusion 103 formed on the second mold 102. Note that the upper surface side of the protruding connecting portion 73 is also in contact with the second mold 102.

[0039] Then, by flowing the molding material M into the lower part of the resin member 70 and the gap between the first mold 101 and the second mold 102 facing them, the automotive door glass catch 100 is integrally molded on the outer side of the glass run 40. At this time, the upper end on the vehicle exterior side of the resin member 70 and the lower half of the connecting wall portion 45 of the attachment portion 41 of the glass run 40 are also molded, and are connected to the extrusion molding portion of the glass run 40 sandwiched between the first mold 101 and the second mold 102. Further, the molded layer M1 molded on the vehicle interior side of the resin member 70 is formed so as to extend to the lower part of the approximate center of the protruding connecting portion 73 including the outer lip portion 54 of the glass run 40. The bottom wall portion 44 of the attachment portion 41 of the glass run 40 is composed of the protruding connecting portion 73 on the vehicle interior side, and the vehicle exterior side is composed of the overlapping of the protruding connecting portion 73 and the molded layer M1 and is thickened. Furthermore, the vehicle interior side of the protruding connecting portion 73 is integrally connected to the upper part on the vehicle exterior side of the vehicle interior side wall portion 51 molded together with the vehicle interior side seal lip portion 53 and the mold lip portion 55.

[0040] The glass catch 100 for an automobile door of the present embodiment is one in which a stainless steel insert panel 60 is embedded as a core material and is integrally molded with the glass run 40. Therefore, the number of processing steps can be reduced as compared with a case where the glass catch 100 for an automobile door and the glass run 40 are separate bodies, and the appearance is also good. In addition, since the entire circumference of the insert panel 60 is completely covered by the resin member 70, the metal surface of the insert panel 60 is not exposed to the vehicle exterior side and the vehicle interior side. According to this, there is no concern about rust of the insert panel 60, and the rigidity is also improved.

[0041] At this time, the surface of the resin member 70 is exposed. However, as shown in FIG. 2, by attaching the decorative mold 80 to the vehicle exterior side, the exposed amount can be reduced, and since the exposed portion is also the same color as the molded layer M1, the appearance is not significantly deteriorated.

[0042] In addition, when integrally molding the glass catch 100 for an automobile door with the glass run 40, when setting the insert panel 60 to be embedded between the first mold 101 and the second mold 102, the upper part on the outer side of the vehicle of the resin member 70 is brought into contact with the inner surface of the first mold 101, and the upper part on the inner side of the vehicle of the resin member 70 is brought into contact with the inner surface of the second mold 102 and set in this state. Thus, the position of the insert panel 60 can be stabilized, and the glass catch 100 for an automobile door with a desired shape and size can be easily manufactured by pouring the molding material M.

[0043] In addition, as shown in FIGS. 9 to 11, upper through holes 62a and 62b are formed in the upper part of the insert panel 60, and annular fitting parts 78a and 78b protruding toward the inner side of the vehicle are formed in the resin member 70. When covering the insert panel 60 with the resin member 70, the annular fitting parts 78a and 78b may be inserted into the upper through holes 62a and 62b from the outer side of the vehicle. Here, FIG. 9(b) shows a longitudinal section passing through the upper through hole 62a, and FIG. 11 shows a part molded in FIG. 9(b). In addition, in the present embodiment, the mold has a structure of only the first mold 101 and the second mold 102, but depending on the shape of the seal lip of the glass run 40 or the like, it may have a structure divided into more molds.

[0044] A recess H opening toward the inner side of the vehicle is formed in the central part of the annular fitting parts 78a and 78b. When setting the insert panel 60 in a state where the resin member 70 is mounted between the first mold 101 and the second mold 102, second protrusions 104a and 104b formed to protrude outward from the vehicle from the second mold 102 are inserted into the upper through holes 62a and 62b from the inner side of the vehicle and come into contact with the resin member 70 mounted on the outer side surface of the insert panel 60 through the recess H.

[0045] According to this, since the annular fitting portions 78a and 78b of the resin member 70 are inserted into the portions of the upper through holes 62a and 62b formed in the insert panel 60, the metal surface of the insert panel 60 is not exposed. In addition, the insert panel 60 covered with the resin member 70 is locally pressed from the vehicle interior side by the second protrusions 104a and 104b formed in the second mold 102, so that the insert panel 60 can be supported at a more stable position. Thereafter, by flowing the mold molding material M, an automotive door glass catch 100 with high accuracy in shape and size can be easily manufactured.

[0046] In addition, in this embodiment, the entire insert panel 60 is covered with the resin member 70, but various shapes of the resin member 70 can be considered.

[0047] For example, as shown in Fig. 12(a), lower through holes 63a and 63b are formed between the upper through holes 62a and 62b formed in the insert panel 60 and the lower end of the insert panel 60, and the resin member 70 is fixed so as to penetrate the lower through holes 63a and 63b. Also, the inner side of the insert panel 60, more specifically, the inner side surface between the upper through holes 61a and 61b and the lower through holes 63a and 63b may be exposed without being covered with the resin member 70. According to this, the amount of the resin member 70 can be reduced, and the inner side surface of the exposed insert panel 60 can be used for positioning.

[0048] Also, as shown in Fig. 12(b), the protruding connecting portion 73 of the resin member 70 may be omitted. Also, in Figs. 9(b), 12(a), and 12(b), the annular fitting portions 78a and 78b of the resin member 70 are inserted into the upper through holes 62a and 62b formed in the insert panel 60. However, the second protrusions 104a and 104b formed in the second mold 102 may be inserted into the upper through holes 62a and 62b exposed on the inner side of the vehicle without providing the annular fitting portions 78a and 78b so as to abut against the resin member 70 (not shown).

[0049] Furthermore, as shown in FIGS. 13(a) and 13(b), third protrusions 105a and 105b that contact the lower inner surface of the resin member 70 attached to the insert panel 60 may be formed on the second mold 102. According to this, since the lower part of the insert panel 60 covered with the resin member 70 is supported so as to be sandwiched from the outside and inside of the vehicle by the first mold 101 and the second mold 102, the movement of the insert panel 60 can be restricted and stably supported when flowing the molding material M. Also, the insert panel 60 may be formed in an L shape, and the portions extending inside and outside the vehicle may be embedded in the protruding connecting portion 73 of the resin member 70 to further enhance the rigidity.

[0050] Also, the attachment of the resin member 70 to the insert panel 60 is such that, as shown in FIGS. 6 and 7, the insert panel 60 is stored in a storage portion provided in the resin member 70. However, as shown in FIG. 14, after setting the insert panel 60 in a mold (not shown), the molding material can be flowed to form the resin member 70.

[0051] As shown in FIG. 14(a), when the insert panel 60 is set in the upper mold and the lower mold (not shown), pins (not shown) extending from the upper mold enter through holes 61e, 61f, 61g, and 61h provided in the insert panel 60, and thus the insert panel 60 is pressed from above. As shown in FIG. 14(b), the insert panel 60 is supported from below by a protruding portion (not shown) protruding from the lower mold and contacting a portion 61r of the insert panel 60 exposed inside the vehicle. Note that, in order to strengthen the adhesive force between the insert panel 60 and the resin member 70, further through holes may be formed in the insert panel 60 so that the resin member 70 can enter.

[0052] In this embodiment, the glass run 40 on which the glass catch 100 for an automobile door is molded is of the hidden type that is attached along the outside of the vehicle of the frame body 10 and covers and hides a part of the frame body 10 from the outside of the vehicle. However, as shown in FIG. 17 (conventional example), it can also be applied to a glass run of the type that is fitted from below to the frame body 10. Particularly, for the hidden type glass run 40, since the stainless steel insert panel 60 is used to firmly attach it to the flange 10B of the frame body 10, after attaching the resin member 70 to the insert panel 60 as in the glass catch 100 for an automobile door of this embodiment and then performing molding, it is effective in that the metal surface is not exposed and the support of the insert panel 60 during molding is stabilized.
