Abstract
Description
Glass catch for automobile door and manufacturing method thereof
[0001] The present invention relates to an automobile glass catch provided on a glass run attached to a window frame of an automobile door to guide the door glass, and a method for manufacturing the same.
[0002] As shown in Figures 7 to 9, a window frame 10 of an automobile door 1 is provided with glass runs 20, 30 for guiding a door glass 2 that rises and falls, and glass catches (glass guides) 25, 35 are provided on the glass runs 20, 30 to reinforce the glass runs 20, 30 (see, for example, Patent Documents 1 and 2).
[0003] The glass catch 25 shown in Figure 8 is separate from the glass run 20, and has a fixing plate 26 that protrudes from the glass catch 25 toward the vehicle interior and is attached to the exterior of the glass run 20 by inserting it from the exterior of the glass run 20. In this way, when the glass catch 25 is separate from the glass run 20, the number of parts increases, and the fixing plate 26 needs to be precisely engaged with the glass run 20, which increases the number of processing steps. In addition, a seam is created between the glass run 20 and the glass catch 25, so it is necessary to devise a way to make the seam inconspicuous.
[0004] In contrast, the glass catch 35 shown in FIG. 9 is integrally molded with the glass run 30, and therefore the number of parts and the number of processing steps do not increase, and the appearance is good.
[0005] Japanese Patent Application Laid-Open No. 2020-93626 Japanese Utility Model Application Laid-Open No. 56-133069
[0006] 9 has a core material 37 embedded in it, but when the glass run 30 and the glass catch 35 are molded simultaneously, 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, if molding is performed with a pin protruding from the mold and its tip pressed against the surface of the core material 37, the glass run 30 will have an outer surface with a hole in the part where the pin was pressed, and the surface of the core material 37 will be partially exposed, resulting in an unattractive appearance.
[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a glass catch for an automobile door that has excellent appearance quality without increasing the number of parts or the number of processing steps, and a method for manufacturing the same.
[0008] In order to achieve the above object, the glass catch for an automobile door of the present invention is attached to a window frame (10) provided on an automobile door (1), and is molded into a glass run (40) having an interior side wall portion (51) that guides the rising and falling door glass (2) into a groove portion, an exterior side wall portion (52), and a bottom wall portion (44) that connects both side wall portions (51, 52), wherein the exterior side wall portion (52) of the glass run (40) has a core material (60), and a fixing member (70) is attached to the core material (60) and has protrusions (71, 72) that protrude from at least one of the exterior side surface and the interior side surface of the core material (60), and the fixing member (70) abuts the protrusions (71, 72) against the mold when the mold is closed, thereby fixing the core material (60) itself within the mold.
[0009] Further, the present invention provides a method for manufacturing a vehicle having a core material (60) that is a stainless steel insert panel (60) having at least two through holes (61 a, 61 b), a fixing member (70) having the protrusions (71, 72) that is a resin member (70) having an outer protrusion (71) and an inner protrusion (72) that protrude from the outer side and the inner side of the insert panel (60), respectively, and the resin member (70) is attached to the insert panel (60) by being wrapped around the insert panel (60) so as to surround the space between the two through holes (61 a, 61 b), The insert panel (60) is covered by an exterior molded layer (M1) provided on the exterior side of the insert panel (60) up to the height position of the end (71a) of the exterior protrusion (71), and an interior molded layer (M2) provided on the interior side of the insert panel (60) up to the height position of the end (72a) of the interior protrusion (72).
[0010] The present invention is also characterized in that the two through holes (61a, 61b) are formed at the lower end of the insert panel (60) in a position that is in the fore-and-aft direction of the vehicle when the door (1) is closed.
[0011] The present invention is also characterized in that upper through holes (61c, 61e) are formed above the lower end of the insert panel (60) in which the two through holes (61a, 61b) are formed.
[0012] The method for manufacturing a glass catch for an automobile door of the present invention is a method for manufacturing a glass catch (100) of an embedded type having a core (60) molded to partially expand and protrude downward from the exterior side wall (52) of a glass run (40) attached to a window frame (10) provided on an automobile door (1) and having an interior side wall (51) for guiding a door glass (2) that moves up and down into a groove, an exterior side wall (52), and a bottom wall (44) connecting both side wall portions (51, 52), wherein the core (60) is a stainless steel insert panel (60) having at least two through holes (61 a, 61 b) formed therein, and a resin member (70) having an exterior protruding portion (71) and an interior protruding portion (72) that protrude from the exterior side surface and the interior side surface, respectively, is attached to the lower end of the insert panel (60) by wrapping around the area between the two through holes (61 a, 61 b), The insert panel (60) is set between a first mold (101) and a second mold (102) with the exterior-side protruding portion (71) abutting against the inner surface of the first mold (101) and the interior-side protruding portion (72) abutting against the inner surface of the second mold (102), and then a molding material (M) is poured into a gap surrounded by the exterior and interior side surfaces of the insert panel (60), the opposing first mold (101) and second mold (102), and the resin member (70), thereby integrally molding the exterior side of the glass run (40). Note that the mold may consist of only the first mold (101) and the second mold (102), but depending on the shape of the glass run (40), one or more additional molds may be present in addition to the first mold (101) and the second mold (102).
[0013] The present invention is also characterized in that the two through holes (61a, 61b) are formed at the lower end of the insert panel (60) in a position that is in the fore-and-aft direction of the vehicle when the door (1) is closed.
[0014] Furthermore, the present invention is characterized in that upper through holes (61c, 61e) are formed above the lower end of the insert panel (60) in which the two through holes (61a, 61b) are formed, and the second mold (102) is formed with protrusions (102a, 102a) that are inserted into the upper through holes (61c, 61e) from the inside of the vehicle but do not abut on the first mold (101).
[0015] It should be noted that symbols in parentheses indicate corresponding elements or matters described in the drawings and in the detailed description to be described later.
[0016] The glass catch for automobile doors of the present invention has a stainless steel insert panel embedded as a core material and is molded integrally with the glass run, which reduces the number of processing steps compared to separate parts and provides a good appearance. Furthermore, the core material is fitted with a fixing member having a protrusion that protrudes from at least one of the exterior and interior surfaces of the vehicle, so the glass catch for automobile doors can be molded integrally with the glass run without leaving any holes on the surface.
[0017] Furthermore, a resin member having an exterior-facing protrusion and an interior-facing protrusion is wrapped around the insert panel so as to go around the two through holes formed in the insert panel, and the insert panel is covered by the exterior-facing molded layer and the interior-facing molded layer provided on the exterior and interior sides of the insert panel, so that the metal surface is not exposed on the exterior or interior sides of the vehicle. Although the ends of the exterior-facing protrusion and the interior-facing protrusion of the resin member are exposed, they are only slightly exposed due to the resin, so the appearance is not significantly impaired.
[0018] Furthermore, when a glass catch for an automobile door is molded integrally with a glass run, if the embedded insert panel is set between the first mold and the second mold, the position of the insert panel can be stabilized by abutting the outer protruding portion of the resin member against the inner surface of the first mold and the inner protruding portion of the resin member against the inner surface of the second mold, so that the molded material can be poured in and the glass catch for an automobile door of the desired shape and size can be easily manufactured.
[0019] Furthermore, the two through holes into which the resin members are attached are formed at the lower end of the insert panel in a position that faces the fore-and-aft direction of the vehicle when the door is closed. Therefore, when the glass catch for an automobile door is molded integrally with the glass run, the lower end of the insert panel can be positioned by abutting it against the first mold and the second mold via the resin members.
[0020] In addition, an upper through hole is formed above the lower end of the insert panel where the two through holes are formed, so that when the glass catch for an automobile door is molded integrally with the glass run, the molding material flows into the upper through hole, thereby restricting and supporting the movement of the insert panel.
[0021] In the method for manufacturing a glass catcher for an automobile door of the present invention, the insert panel is placed between a first mold and a second mold, with the exterior-facing protruding portion of the resin member abutting against the inner surface of the first mold and the interior-facing protruding portion of the resin member abutting against the inner surface of the second mold, and after that, the protrusion formed in the second mold is inserted into the upper through-hole formed in the insert panel from the interior side of the vehicle, and then a molding material is poured into the gap surrounded by the exterior and interior sides of the insert panel, the opposing first and second molds, and the resin member, so that the insert panel is supported by the molds on both the upper and lower sides. This allows the insert panel to be supported in a more stable position between the first and second molds, and then by pouring the molding material, an automobile door glass catcher with high shape and size precision can be easily manufactured.

[0023] 1 to 6, a glass catch for an automobile door and a method of manufacturing the same according to an embodiment of the present invention will be described. Note that the same reference numerals are used to designate the same parts as those shown in the conventional example.
[0024] As shown in Figures 1 and 6, 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 edge) of the window frame (frame body) 10 provided on the door 1 of an automobile, and is molded so as to partially expand and protrude downward relative to the exterior side of the glass run 40 that guides the door glass 2 into a groove as it moves up and down, and has a core material 60 embedded inside.
[0025] As shown in FIG. 2, this glass run 40 is extruded and is a hidden type that is attached along the exterior side of the window frame 10 and covers and conceals part of the window frame 10 from the exterior of the vehicle. As shown in FIG. 1, the glass catch 100 for automobile doors is formed by partially cutting out the extruded glass run 40 and molding the cut-out portion.
[0026] As shown in Figure 2, the glass run 40 has an attachment portion 41 that is attached from the outside of the vehicle to the flange 10F that extends toward the outside of the vehicle on the window frame 10, and a main body portion 42 that forms a groove on the inside and guides the door glass 2 into the groove as it rises and falls.
[0027] The mounting portion 41 has a generally U-shaped cross section and is made up of an upper wall portion 43 extending in the vehicle interior / 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. On the inside, a locking portion 46 that elastically contacts the flange 10F and a lip portion 47 are formed. A body seal lip portion 48 that elastically contacts the periphery of the opening in the vehicle body and seals between the body and the door 1 is protruded from the upper surface of the upper wall portion 43 at approximately the center thereof.
[0028] The main body 42 includes the bottom wall 44, which guides the door glass 2 into the groove as it moves up and down, and an interior side wall 51 and an exterior side wall 52, which extend downward from the interior and exterior sides of the bottom wall 44. An inner lip 53 is provided on the exterior side of the end of the interior side wall 51, extending toward the exterior and making sliding contact with the interior side of the door glass 2. An outer lip 54 is provided on the interior side of the end of the exterior side wall 52, extending toward the interior and making sliding contact with the exterior side of the door glass 2. A molding lip 55 is also provided on the interior side of the end of the interior side wall 51. A seal lip that elastically contacts the edge of the door glass 2 may be provided below the bottom wall 44. The connecting wall 45 of the mounting portion 41 and the exterior side wall 52 of the main body 42 are vertically continuous, allowing a decorative molding, such as an optical molding, to be attached to their exterior sides.
[0029] As shown in FIG. 3 , the core material 60 is an L-shaped stainless steel (SUS) insert panel 60, with the shorter side of the L-shape embedded in the bottom wall 44 of the glass run 40 and the longer side embedded in the exterior side wall 52. The insert panel 60 also has a plurality of through holes (eight in this example) 61a-61h formed therein. The through holes 61a and 61b are formed at the lower end of the longer sides of the insert panel 60, spaced apart in positions that correspond to the longitudinal direction of the vehicle when the door 1 is closed. The through holes 61c, 61d, and 61e are formed at the upper end of the longer sides of the insert panel 60, spaced apart in positions that correspond to the longitudinal direction of the vehicle when the door 1 is closed. The through holes 61f, 61g, and 61h are formed at the middle of the longer sides of the insert panel 60, spaced apart in positions that correspond to the longitudinal direction of the vehicle when the door 1 is closed.
[0030] As shown in Fig. 4, the insert panel 60 has an exterior protruding portion 71 and an interior protruding portion 72 that protrude from the exterior and interior sides, respectively. A resin member 70, which functions as a fixing member, is attached to the insert panel 60 by wrapping it around the two through holes 61a, 61b. More specifically, the resin member 70 is an integral unit of exterior and interior strip portions 73a, 73b that are in close contact with the exterior and interior sides of the insert panel 60 between the two through holes 61a, 61b, respectively, and two through holes 74, 74 that pass through the two through holes 61a, 61b without any gaps. The exterior protruding portion 71 protrudes from the exterior side of the two through holes 74, 74, and the interior protruding portion 72 protrudes from the interior side of the two through holes 74, 74. Note that the resin member 70 may be provided on at least one of the exterior protruding portion 71 and the interior protruding portion 72. When the mold is closed, the resin member (fixing member) 70 abuts both protruding portions 71 and 72 against the mold, thereby fixing the core material 60 itself within the mold.
[0031] 1, the portion of the glass run 40 on which the automobile door glass catch 100 is provided is formed by extrusion molding of the mounting portion 41 excluding the bottom wall portion 44 of the glass run 40, and molding the rest, i.e., the main body portion 42 of the glass run 40, which is integrally formed with the automobile door glass catch 100, by molding. The insert panel 60 is entirely covered, and an exterior molded layer M1 is provided on the exterior side of the insert panel 60 up to the height position of the end 71a of the exterior protrusion 71, and an interior molded layer M2 is provided on the interior side of the insert panel 60 up to the height position of the end 72a of the interior protrusion 72.
[0032] The automobile door glass catch 100 configured as described above is manufactured as follows: First, the main body 42 (including the bottom wall 44) of the extruded glass run 40 and the lower half of the connecting wall 45 of the mounting portion 41 are cut out by a predetermined length in the longitudinal direction of the glass run 40, and the remaining portion of the mounting portion 41 is sandwiched between a first mold 101 and a second mold 102 as shown in FIG.
[0033] Next, the insert panel 60 with the resin member 70 attached is set between the first mold 101 and the second mold 102, with the exterior protruding portion 71 of the resin member 70 abutting against the inner surface of the first mold 101 and the interior protruding portion 72 of the resin member 70 abutting against the inner surface of the second mold 102.
[0034] Then, by pouring molding material M into a gap surrounded by the exterior and interior side surfaces of the insert panel 60, the opposing first and second molds 101 and 102, and the resin member 70, the automobile door glass catch 100 is molded integrally on the exterior side of the glass run 40. At this time, the main body 42 (including the bottom wall 44) of the glass run 40 and the lower half of the connecting wall 45 of the mounting portion 41 are molded and connected to the extrusion molded portion of the glass run 40 sandwiched between the first and second molds 101 and 102. The molding material M also flows into the through holes 61c, 61d, 61e, 61f, 61g, and 61h formed in the insert panel 60, restricting the movement of the insert panel 60.
[0035] The automobile door glass catch 100 of this embodiment has a stainless steel insert panel 60 embedded as a core material and is molded integrally with the glass run 40. This reduces the number of manufacturing steps compared to a glass catch 100 and glass run 40 that are separate components, and provides a more attractive appearance. Furthermore, a resin member 70 having an exterior-side protrusion 71 and an interior-side protrusion 72 is wrapped around the insert panel 60, surrounding the two through holes 61a, 61b formed in the insert panel 60. The insert panel 60 is concealed by the exterior-side molded layer M1 and the interior-side molded layer M2 provided on its exterior and interior sides, so that the metal surfaces of the insert panel 60 are not exposed to the exterior or interior of the vehicle. Although the ends of the exterior-side protrusion 71 and the interior-side protrusion 72 of the resin member 70 are exposed, they are only slightly exposed by the resin, and therefore do not significantly impair the appearance.
[0036] Furthermore, when the glass catch 100 for automobile doors is molded integrally with the glass run 40, if the embedded insert panel 60 is set between the first mold 101 and the second mold 102, the position of the insert panel 60 can be stabilized by abutting the outer protruding portion 71 of the resin member 70 against the inner surface of the first mold 101 and the inner protruding portion 72 of the resin member 70 against the inner surface of the second mold 102, and therefore the mold-forming material M can be poured in to easily manufacture the glass catch 100 for automobile doors of the desired shape and size.
[0037] Furthermore, the two through holes 61a, 61b into which the resin member 70 is attached are formed at the lower end of the insert panel 60 in a position that is in the fore-and-aft direction of the vehicle when the door 1 is closed. Therefore, when the glass catch 100 for automobile doors is molded integrally with the glass run 40, the lower end of the insert panel 60 can be positioned by abutting it against the first mold 101 and the second mold 102 via the resin member 70.
[0038] In addition, a plurality of through holes 61c, 61d, 61e, 61f, 61g, and 61h are formed above the lower end of the insert panel 60 where the two through holes 61a and 61b are formed. Therefore, when the glass catch 100 for automobile doors is molded integrally with the glass run 40, the molding material M flows into these through holes 61c, 61d, 61e, 61f, 61g, and 61h, thereby effectively restricting and supporting the movement of the insert panel 60.
[0039] 6, two protrusions 102a, 102a extending toward the first mold 101 (extending from the vehicle interior side toward the vehicle exterior) can be formed on the second mold 102, and the protrusions 102a, 102a can be inserted from the vehicle interior side into upper through-holes 61c, 61e formed above the insert panel 60 set between the first mold 101 and the second mold 102 to fix the upper part of the insert panel 60. The two protrusions 102a, 102a formed on the second mold 102 extend toward the first mold 101, but are non-contacting protrusions that do not reach the first mold 101, so that the molding material M flows between the tips of the protrusions 102a, 102a and the first mold 101. The molding material M flows directly into the through-holes 61d, 61f, 61g, 61h to support the insert panel 60.
[0040] According to this, at the lower end side of the insert panel 60 between the first mold 101 and the second mold 102, the vehicle exterior protrusion 71 and the vehicle interior protrusion 72 of the resin member 70 attached to the lower end side are abutted against the first mold 101 and the second mold 102, and at the upper end side of the insert panel 60, the two protrusions 102a, 102a formed on the second mold 102 are inserted into the upper through-holes 61c, 61e formed above the insert panel 60 from the vehicle interior side and fixed, so that the insert panel 60 can be supported in an even more stable position, and then, by pouring the molding material M, it is possible to easily manufacture an automobile door glass catch 100 with high accuracy in shape and size. Note that, although the portions of the insert panel 60 where the two protrusions 102a, 102a formed on the mold 102 are inserted into the upper through-holes 61c, 61e are exposed, they are on the vehicle interior side and do not particularly impair the external appearance.
[0041] In this embodiment, the glass run 40 from which the automobile door glass catch 100 is molded is a hidden type that is attached along the exterior side of the window frame 10 and covers and conceals part of the window frame 10 from the exterior of the vehicle, but it can also be applied to a type of glass run that is fitted into the window frame 10 from below, as shown in Figure 9 (conventional example). In particular, the hidden type glass run 40 uses a stainless steel insert panel 60 for firm attachment to the flange 10B of the window frame 10, so molding the automobile door glass catch 100 after attaching the resin member 70 to the insert panel 60 in this embodiment is effective in preventing the metal surface from being exposed and in stably supporting the insert panel 60 during molding.
