Description

  The present invention relates to a glass run assembly structure, and more particularly to a glass run assembly structure assembled to a door frame having no channel member.

  Conventionally, as shown in FIG. 6, a glass run 60 that seals the peripheral portion of the door glass G that moves up and down is attached to a vehicle door such as an automobile along the inner peripheral side of the door frame 61.

  Generally, the door frame 61 includes an inner panel 62, an outer panel 63, and a channel member 64. On the other hand, the glass run 60 includes a bottom wall portion 65 and a pair of side wall portions 67, 68 extending from both ends of the bottom wall portion 65, and a body portion 69 having a substantially U-shaped cross section, and both side wall portions 67 of the body portion 69. , 68 extends from the front end of the main body 69 to the inside of the main body 69 and seals the door glass G, and a molding that extends from the front ends of both side walls 67, 68 of the main body 69 to the outside of the main body 69. Lips 73 and 74 are provided. In the assembled state of the glass run 60, the main body 69 of the glass run 60 is fitted into the channel member 64, and the end portions of the flanges 75 and 76 formed by the panels 62 and 63 and the channel member 64 are glass. The run 60 is inserted between the side wall portions 67 and 68 and the molding lips 73 and 74. Thus, conventionally, in the upper side portion of the door frame 61, since the upward movement of the glass run 60 is restricted by the channel member 64, even when pushed up by the door glass G, it is pushed up further. The glass run 60 is maintained in a proper position.

However, in recent years, a door frame 61 in which the channel member 64 is omitted has been proposed in order to reduce the weight of the door and simplify the manufacturing process. In such a configuration, when the door glass G is closed, the bottom wall portion 65 of the main body 69 is pushed into the door frame 61 by the door glass G at the upper side of the glass run 60, and the shape of the glass run G is Deforms greatly. At this time, the molding lips 73 and 74 disposed on the outer surfaces of the panels 62 and 63 are pulled and separated from the panels 62 and 63, and there is a possibility that the appearance quality is deteriorated (see FIG. 8). In recent years, as shown in FIG. 7, a stopper member 80 is mounted in the door frame 61 to restrict the movement of the glass run 60 (see, for example, Patent Document 1). ).
JP 2000-103242 A

  However, in a general door, the inner panel 62 and the outer panel 63 press-molded in a predetermined shape are overlapped, and the upper edge portion 63a of the outer panel 63 is bent so as to sandwich the upper end portion 62a of the inner panel 62. Hemming is applied. Here, when hemming is performed, the upper edge 63a of the outer panel 63 is generally bent toward the vehicle inner side (inner panel side) in order to suppress deterioration in appearance quality. Under such a configuration, the stopper member 80 is positioned in the vertical direction by contacting the bottom wall portion 62 b of the inner panel 62. Therefore, when there is an assembly error between the inner panel 62 and the outer panel 63, the distance between the glass run 60 and the stopper member 80 may not be stable. As a result, as shown in FIG. 8, when the relative position of the bottom wall 62 b of the inner panel 62 with respect to the outer panel 63 is shifted upward from the appropriate position, the glass run 60 is moved inside the door frame 61 by the door glass G. The molding lip 74 on the outside of the vehicle is pulled to open the mouth. On the contrary, as shown in FIG. 9, when the relative position of the bottom wall portion 62 b of the inner panel 62 with respect to the outer panel 63 is shifted downward from the appropriate position, the molding lip 74 on the vehicle outer side is bulged. There was a risk of becoming. As a result, there is a possibility that appearance quality is deteriorated.

  Since the molding lip 74 on the outer side of the vehicle is located on the outer side of the outer panel 63, it particularly affects the appearance quality. Further, in recent years, the outer surface 63 has a flush surface in which the outer side surface of the outer panel 63 is substantially flush with the outer side surface of the door glass G, so the side wall portion 68 on the outer side of the vehicle is relatively shorter than the side wall portion 67 on the inner side of the vehicle. In addition to the formation, the seal lip 72 and the molding lip 74 on the outside of the vehicle are also set to be relatively small (shorter) than the sealing lip 71 and the molding lip 73 on the inside of the vehicle. Even if it can be absorbed inside the vehicle, it may be easily affected by the outside.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a glass run that can suppress deterioration in the appearance quality of a glass run assembled to a door frame that does not have a channel member. It is to provide an assembly structure.

  In the case of the configuration of the means 6, the problem as described in the above problem is likely to occur. However, such a problem is effectively suppressed by the structure of each of the means.

  Hereinafter, an embodiment will be described in detail with reference to the drawings. As shown in FIG. 1, an automobile door (a front door in the figure: simply referred to as “door” in the figure) 1 as a vehicle door that can be opened and closed at an opening of an automobile body as a vehicle body is a door that can be raised and lowered. Corresponding to the outer peripheral shape of the door glass G, a glass run 2 made of EPDM (ethylene-propylene-diene copolymer rubber) is provided.

  The glass run 2 includes an extrusion molding portion 3 corresponding to the upper side portion in the longitudinal direction, extrusion molding portions 4 and 5 corresponding to the front and rear vertical side portions, and ends of the extrusion molding portions 3, 4 and 5. It is comprised from the shaping | molding parts 6 and 7 (part which attached | subjected the dot pattern in FIG. 1) to connect. Each of the extrusion molding portions 3 to 5 is formed in a substantially linear shape (in a long shape) by an extruder (not shown). In addition, the molding parts 6 and 7 are connected and molded by a mold apparatus (not shown) so that the two extrusion molding parts 3 and 4 and the extrusion molding parts 3 and 5 are connected to each other at a predetermined angle. Is done.

  Next, the configuration of the upper side portion (extrusion molding portion) 3 of the glass run 2 and the configuration of the door frame 1a of the door 1 to which the glass run 2 is attached will be described in detail with reference to FIGS. 2 is a partial cross-sectional view taken along the line JJ of FIG. 1 showing a general portion of the upper side of the door frame 1a, and FIG. 3 is a partial cross-sectional view taken along the line KK of FIG. FIG.

  The upper side portion of the door frame 1a includes an inner panel 51 disposed on the inner side of the vehicle and an outer panel 52 disposed on the outer side of the vehicle. More specifically, a so-called hemming process is performed in which the upper edge portion 52a of the outer panel 52 is bent so as to sandwich the upper end portion 51a of the inner panel 51, and both the panels 51 and 52 are integrally joined. Here, when the hemming process is performed, the upper edge portion 52a of the outer panel 52 is bent toward the vehicle inner side (the inner panel 51 side) in order to suppress deterioration in appearance quality. The door frame 1a in the present embodiment has a channelless structure in which a channel member having a substantially U-shaped cross section for fitting the glass run 2 is not provided. Therefore, the glass run 2 is attached between the inner panel 51 and the outer panel 52.

  Next, the structure of the upper side part (extrusion molding part) 3 of the glass run 2 is demonstrated. The upper side 3 of the glass run 2 includes a bottom wall 10, a main body 13 having a substantially U-shaped cross section including a vehicle inner side wall 11 and a vehicle outer side wall 12 extending from both ends of the bottom wall 10, and the vehicle inner side. A pair of seal lips 14 and 15 extending from the side wall 11 and the vehicle outer side wall 12 to the inside of the main body 13 and sealing with the door glass G, and both side walls 11 and 12 of the main body 13 are substantially omitted. Mold lips 17 and 18 extending from the tip to the outside of the main body 13 are provided.

  In the assembled state of the glass run 2, the main body 13 of the glass run 2 is fitted between the inner panel 51 and the outer panel 52, and the lower edge portions 51b and 52b of the panels 51 and 52 are respectively glass run. 60 are inserted between the side wall portions 11 and 12 and the molding lips 17 and 18.

  The vehicle outer side wall portion 12 is formed to be relatively shorter than the vehicle inner side wall portion 11, and the vehicle outer seal lip 15 and molding lip 18 are associated with the vehicle inner sealing lip 14 and molding lip 17. It is set to be relatively small (short) compared to. Thus, the flash surface is formed so that the vehicle outer side surface of the outer panel 52 is substantially flush with the vehicle outer side surface of the door glass G.

  In this embodiment, as shown in FIGS. 3 and 4, stopper members 25 as restricting members are attached to the upper side of the door frame 1 a at two locations in the longitudinal direction. FIG. 4 is a schematic perspective view showing the configuration of the door frame 1a.

  The stopper member 25 is made of, for example, a metal member. The stopper member 25 is opposed to the bottom wall portion 10 of the glass run 2 and restricts the upward movement of the door glass 2, the vehicle inner side fixing portion 27 extending from both ends of the restriction portion 26, and the vehicle outer side. It consists of a fixed portion 28 and is configured to have a substantially U-shaped cross section.

  The front end portions 27a and 28a of the vehicle inner side fixing portion 27 and the vehicle outer side fixing portion 28 are formed to be bent outward. And the stopper member 25 is fixed with respect to the door frame 1a so that the lower edge parts 51b and 52b of each panel 51 and 52 are clamped by the main-body part of each fixing | fixed part 27 and 28, and front-end | tip part 27a and 28a. ing. In the assembled state of the glass run 2, the tip portions 27 a and 28 a of the fixing portions 27 and 28 are covered with the molding lips 17 and 18 of the glass run 2, and deterioration of the appearance quality is suppressed.

  Further, at the location where the stopper member 25 is provided, the steps formed on the inner side of the stopper member 25 are the locking lips 21 and 22 provided on the side wall portions 11 and 12 in the assembled state of the glass run 2. Locked to the portions 27b and 28b.

  As described above in detail, in the present embodiment, in the door frame 1a having no channel member, the upward movement of the glass run 2 is restricted by the stopper member 25 fixed to the inner panel 51 and the outer panel 52. Therefore, even when the glass run 2 is pushed up by the door glass G at the upper side of the door frame 1a, the glass run 2 is not pushed up any more, and the glass run 2 is maintained at an appropriate position.

  In this embodiment, since the stopper member 25 is fixed to at least the outer panel 52, the relative position of the inner panel 51 with respect to the outer panel 52 is caused by an assembly error between the inner panel 51 and the outer panel 52. Even when it deviates from the proper position, the relative position of the glass run 2 with respect to the outer panel 52 does not change. Therefore, the molding lip 18 on the outside of the vehicle, which is the portion of the outer panel 52 that has an influence on the external appearance quality, is maintained in a properly assembled state with the outer panel 52. For example, the relative position of the inner panel 51 with respect to the outer panel 52 is shifted upward from the appropriate position, the glass run 2 is pushed into the door frame 1a by the door glass G, and the molding lip 18 on the outside of the vehicle is pulled to open the mouth. In addition, the relative position of the inner panel 51 with respect to the outer panel 52 is deviated downward from the appropriate position, and the problem that the molding lip 18 on the outside of the vehicle bulges out can be suppressed. As a result, deterioration in appearance quality can be suppressed.

  In addition, since the stopper member 25 is separate from the glass run 2, the configuration of the glass run 2 can be used without changing from the conventional one, and as a result, an increase in manufacturing cost can be suppressed.
