Japanese Patent No. 3755080

  However, the structure described in Patent Document 1 focuses on the moldability of the molded part and the workability of assembling the fixed plate. There are still challenges. For example, when the door weather strip is transported or transported with the fixed plate temporarily fixed, or when the door weather strip is assembled in the vehicle assembly process, the fixed plate falls off the door weather strip due to vibration or external force. There is still room for improvement. In particular, when a deformation force that causes a so-called opening in the direction in which the angle formed between the corner piece portion and the hollow seal portion in the mold forming portion is increased, the fixing plate is peeled off from the corner piece portion. When a strong force is applied, the fixed plate tends to come off anyway.

  The present invention has been made paying attention to such problems, and is considered so that the outsert clip corresponding to the fixed plate attached to the door weather strip in a temporarily fixed state can be prevented from falling off. Provide a structured.

  According to the first aspect of the present invention, a plate is attached to a tongue-shaped attachment base portion formed adjacent to a hollow lip among mold parts of a door weather strip to be mounted around a door of an automobile. The clip body portion of the outsert clip formed by protruding the locking shaft portion on the back surface of the clip-shaped clip body portion is arranged so as to be seated, and the locking shaft portion is formed on each of the mounting base portion and the door panel. It is premised on the structure of an automobile door weather strip in which the mounting base portion is sandwiched and fixed between the door panel and the clip main body portion by being inserted and locked into the mounting hole.

  In addition, since the base portion of the hollow lip and a part of the mounting base portion are overlapped in the vehicle width direction, a groove portion is formed between them, and the base portion of the hollow lip is engaged with the base portion. While the joint hole is formed, the end of the clip body portion of the outsert clip is inserted into and fitted into the groove portion, and the end of the clip body portion to be inserted and fitted into the groove portion A holding protrusion that engages with the engagement hole is formed in a protruding manner in the part in a direction opposite to the protruding direction of the locking shaft.

  In this case, from the viewpoint of preventing the outsert clip from falling off, it is more preferable that the claw portion is formed in a hook shape at the tip of the holding projection portion as described in claim 2.

  Further, for the same reason as described above, as described in claim 3, the locking shaft portion and the holding projection portion that are formed to protrude from the clip body portion of the outsert clip are offset from each other in the vehicle longitudinal direction. It is desirable.

  Therefore, in at least the invention described in claim 1, the end portion of the clip body portion on the outsert clip side is inserted and fitted into the groove portion formed between the root portion of the hollow lip and the mounting base portion. The locking shaft portion protruding from the clip main body portion is inserted and locked into the mounting hole of the mounting base portion, and the holding projection formed at the end portion of the clip main body portion is the engagement hole on the hollow lip side. The outsert clip can be temporarily fixed to the door weather strip with the state engaged with the door weather strip.

  According to the present invention, when the door weather strip is transported or transported with the outsert clip temporarily fixed, or when the door weather strip is assembled in the vehicle assembly process, the mounting base portion and the hollow portion at the mold forming portion are hollow. Even when a force is applied that causes a so-called mouth opening in the direction in which the angle between the lip and the lip increases, and a force that peels off the clip body of the outsert clip from the mounting base, The outsert clip can be prevented from falling off.

  As is clear from FIGS. 5 and 6, which are cross-sectional views, a resin-made outsert clip 9 is superposed on the mounting base portion 8 of the molded part 7, and the molded part is formed by the outsert clip 9. 7 is fixed to the door sash 2 that functions as a part of the door panel.

  As shown in FIG. 7, the outsert clip 9 is a relatively large plate-shaped clip main body portion that is substantially similar to the mounting base portion 8 on the mold forming portion 7 side, more specifically, a deformed rectangular shape or a deformed rectangular shape. For example, a prismatic locking shaft portion 11 is integrally formed on the back surface of a vertically long clip body portion 10 having a shape. Then, as shown in FIG. 6, the locking shaft portion 11 is inserted and locked into the square hole-shaped mounting hole 12 formed in the mounting base portion 8 and the square hole-shaped mounting hole formed in the door sash 2. By doing so, the mounting base portion 8 is sandwiched between the door sash 2 and the clip main body portion 10, and the mold forming portion 7 is positioned and fixed. Note that a bead portion 13 is formed on the mounting base portion 8 along the outline of the clip main body portion 10 of the outsert clip 9 that is overlapped with the mounting base portion 8.

  As described above, FIG. 2 shows a state in which the outsert clip 9 is arranged in an overlapping manner with respect to the mounting base portion 8 of the mold forming portion 7, whereby the mounting base portion 8 which is a part of the mold forming portion 7. And the clip body 10 of the outsert clip 9 are superposed so as to be in close contact with each other. At the same time, as shown in FIG. 6, a portion of the mounting base portion 8 close to the corner hollow seal lip 5a and a root portion of the corner hollow seal lip 5a are substantially overlapped in the vehicle width direction. A groove portion 14 is formed between the ends of the long side portions 10a and 10b (see FIG. 7) of the clip main body portion 10 on the long side portion 10a side. Will be pinched.

  Then, as is clear from FIG. 6, the above-mentioned locking is provided on the surface side of the clip main body portion 10 in the outsert clip 9 and on the end portion on the one long side portion 10 a side of the clip main body portion 10. A holding projection 15 is formed in a direction opposite to the protruding direction of the shaft 11. The holding projections 15 are offset from each other in the vehicle front-rear direction with respect to the locking shaft 11 on the surface side of the clip main body 10. A single small engagement hole 16 that faces the groove portion 14 is formed at the base of the corner hollow seal lip 5 a forming the groove portion 14. The holding projection 15 on the main body 10 side is engaged.

  Therefore, as shown in FIGS. 5 and 6 in addition to FIGS. 1 and 2, when the door weather strip 3 is attached to the door 1, when attention is paid to the molded part 7 that is a part of the door weather strip 3, While the clip main body portion 10 of the clip 9 is seated on the mounting base portion 8 of the mold forming portion 7, the locking shaft portion 11 (see FIG. 7) is fitted or locked into the mounting hole on the door sash 2 side. As a result, the molding part 7 is fixedly supported while being positioned on the door sash 2, but the outsert clip 9 is previously attached to the molding part 7 in the state of the door weather strip 3 alone before being assembled to the door sash 2. It shall be attached temporarily and temporarily attached.

  Specifically, the insertion shaft portion 11 of the outsert clip 9 is inserted into the attachment hole 12 (see FIGS. 5 and 6) on the attachment base portion 8 side in the mold forming portion 7, and the attachment base portion 8 The clip main body 10 is seated so as to overlap with the mounting base portion 8 of the mold forming portion 7 so that the contours of both of the clip main body portions 10 are matched. At that time, as shown in FIG. 6, one end of the clip body 10 on the long side 10a (see FIG. 7) side is a groove between the mounting base 8 and the corner hollow seal lip 5a. 14 and sandwich. At the same time, the holding projection 15 formed at the end of the clip main body 10 on the one long side 10a side is engaged with the engagement hole 16 on the corner hollow seal lip 5a side.

  As a result, the outsert clip 9 is not only inserted and supported in the mounting hole 12 formed in the mounting base portion 8 of the mold forming portion 7 in the locking shaft portion 11, but also in one of the clip main body portions 10. After the end on the long side 10 a side is inserted into the groove 14, the holding projection 15 attached to the end on the one long side 10 a is engaged with the engagement hole 16. As a result, the position of the clip main body portion 10 that is superposed so as to be in close contact with the mounting base portion 8 is regulated and is in a temporarily fixed state. Therefore, even if an external force such as a twisting force or vibration is applied to the molding part 7 in the state of the door weather strip 3 alone before being assembled to the door 1, the posture and orientation of the outsert clip 9 should not change. In this case, the outsert clip 9 does not fall off from the mold part 7.

  More specifically, for example, as shown in FIG. 8, in the state of the door weather strip 3 alone with the outsert clip 9, the mounting base portion 8 in the mold forming portion 7 and the corner hollow seal lip 5a are formed. When deformed in the direction in which the angle increases, for example, in the state in which the mounting base portion 8 and the corner hollow seal lip 5a in the molded portion 7 are deformed in a so-called opening direction by an external force F, outsert in the direction of the arrow P Even when a force that peels off the clip 9 is received, the holding projection 15 on the clip body 10 side and the engagement hole 16 on the corner hollow seal lip 5a are engaged, so the outsert clip 9 is positioned. It is possible to prevent a situation in which a deviation or a posture change occurs or the mold forming unit 7 falls off.

  Thus, the outsert clip 9 is stably supported by the mold forming part 7 even when the weather strip 3 is alone, so that the mold forming part 7 is attached to the door sash 2 when the door weather strip 3 is assembled to the door 1. In order to fix it, the direction of the mold forming part 7 is matched with the direction of the door sash 2, and the outsert clip 9 attached to the mold forming part 7 side as shown in FIGS. The locking shaft portion 11 is inserted into the mounting hole on the door sash 2 side and pushed in from the clip main body portion 10 side. By doing so, as shown in FIGS. 5 and 6, the mounting base portion 8 is sandwiched between the door sash 2 and the clip main body portion 10, and the mold forming portion 7 is in a correct position with respect to the door sash 2. It will be assembled while being positioned.

  FIG. 9 shows a second embodiment of an automobile door weather strip according to the present invention, and shows a cross-sectional view of the same portion as FIG. Therefore, the same reference numerals are given to portions common to FIG.

  In the second embodiment shown in FIG. 9, the claw portion 15a is bent and formed so as to be further folded back at the tip of the holding projection 15 in order to further extend the holding projection 15 formed on the clip body 10. Thus, the tip of the holding projection 15 is substantially formed in a bowl shape.

  According to the second embodiment, as shown in FIG. 9, with the holding projection 15 engaged with the engagement hole 16, the claw 15a at the tip further has an inner peripheral surface of the corner hollow seal lip 5a. Therefore, the retainability of the outsert clip 9 with respect to the mounting base portion 8 is further enhanced, and it is further advantageous in preventing the outsert clip 9 from dropping off particularly in the state of the door weather strip 3 alone.

  Here, in the first and second embodiments, the holding projection 15 on the clip body 10 side and the corresponding engagement hole 16 on the corner hollow seal lip 5a are both formed as one. If necessary, two or more holding projections 15 and engagement holes 16 may be formed.
