Description

  The present invention relates to a door weather strip attached to a door frame of an automobile.

  This will be described with reference to FIGS. A door frame 1 of an automobile is attached to a mounting portion 1a, which is an outer peripheral end of the door frame 1, and a trunk portion 12 positioned at an intermediate portion, and a hollow seal portion 13 positioned on the indoor side and elastically contacting the body panel, A weather strip 20 is provided that is located on the vehicle exterior side of the body portion 12 and includes a back rib 11 that elastically contacts the door frame 1 (see FIGS. 1 and 2).

  The rear rib 11 of the weather strip 20 is formed so as to elastically contact the edge curved portion 4 of the door frame 1 (the folded portion of the door outer panel 3) in the straight portion S of the door frame 1. The sealing property between the door frame 1 and the door frame 1 is ensured (see FIGS. 3 and 4. The imaginary line in FIG. 3 indicates the tip of the rear rib 11). This is because the edge bent portion 4 is bent in a straight line with a sufficiently large bending width W in the straight portion S (see FIG. 5).

  However, unlike the straight line portion S, the bent portion 4 is formed with a short bending width (see FIG. 6) or with the bending width short and raised in the corner portion C. (See FIG. 7). Therefore, the back rib 11 is placed at the corner portion C of the door frame 1 over the sealer 5 provided in a raised state between the edge curved portion 4 and the door inner panel 2 as shown in FIG. It is in a state of being detached from the portion 4 (the end 4a of the edge curved portion 4).

  Therefore, the back rib 11 is lifted at two points (P, Q) of the sealer 5, and the back rib 11 is formed at both side portions (Pb-Pb, Qb-Qb and Pc-Pc, Qc-Qc) of each point. And the edge curved portion 4 (see FIG. 8, Pb-Pb or Qb-Qb) and between the back rib 11 and the door inner panel 2 (see FIG. 9, Pc-Pc or Qc-Qc). Will occur. In particular, since the door inner panel 2 is recessed from the edge curved portion 4 (because the gap between the rear rib 11 is large), a large gap G is formed between the rear rib 11 and the door inner panel 2. . Further, even if the rear rib 11 does not get over the sealer 5, it only rides up (see FIG. 10), and there is a gap between both sides (Pb-Pb, Qb-Qb and Pc-Pc, Qc-Qc) in the same manner. G is generated.

  Further, unlike the straight portion S, the sealer 5 is likely to have a variation in the bonding position and height in the corner portion C where the bending width of the edge bent portion becomes narrow. As a result, a gap G is also generated between the back rib 11 and the sealer 5. In addition, there is a problem that intrusion water B enters through these gaps G during high-pressure washing, and the water passes over the water stop beads 14.

  In order to prevent such intrusion water B from entering the room, in the conventional door weather strip 10, as shown in FIGS. 2 and 8, in addition to the water stop bead 14, an ept sealer is provided at the lower end of the body 12. 16 is attached with a double-sided adhesive tape.

Further, as another means for solving the above-described problem, a means for covering the corner portion C of the door frame 1 with a cover tape has been devised (for example, see Patent Document 1).
JP 2007-62532 A

  However, in the prior art in which the opt sealer 16 is provided, it is necessary to stick the ept sealer 16 separately to the lower end portion of the body portion 12 with a double-sided adhesive tape, which increases the molding cost and makes the mounting operation troublesome. There is a problem that productivity is bad.

  Further, the conventional technique for covering the corner portion C with the cover tape has a problem in appearance because the end face of the cover tape is formed in a bellows shape.

  The present invention has been devised in view of these points, and it is an object of the present invention to provide a door weather strip that does not allow intrusion of water into the room from the corner portion of the door frame and is excellent in productivity and appearance.

  This will be described with reference to FIGS. 1, 11 and 12. The door weather strip 10 according to claim 1 is provided with a bottom surface portion 10a for mounting attached to a mounting portion 1a of a door frame 1 of an automobile, a trunk portion 12 located in the center, and a position on the indoor side of the trunk portion 12. A hollow seal portion 13 that elastically contacts the body panel, a rear rib 11 that is positioned outside the body portion 12 and elastically contacts the door frame 1, and is provided between the mounting bottom surface portion 10 a and the rear rib 11. And a water stop bead 14 elastically contacting the door frame 1.

  And in the attachment surface (surface facing the door inner panel 2) of the fin part F attached to the corner part C of the door frame 1, the protrusion height which elastically contacts the door frame 1 on the inner peripheral side of the corner part F1 And a wall having a length that hangs continuously from the horizontal portion of the back rib 11 and has a lower end adjacent to the water stop bead 14 and forming a discharge recess 19 between the water stop bead 14. The part 17 is provided by integral molding.

  Thereby, the intrusion water B that has entered from the gap G between the corner portion C of the door frame 1 and the back rib 11 can be blocked by the wall portion 17 provided in the fin portion F.

In addition to the structure of claim 1, the door weather strip 10 according to claim 2 is a back surface in which intrusion water B that has entered from between the corner portion of the door frame 1 and the fin portion F is provided in the fin portion F. The water stop bead 14 prevents the intrusion water B from being discharged from the discharge groove 18 formed between the lower end of the rib 11 vertical part and the water stop bead 14 and over the wall 17. And it discharges out of the vehicle from the discharge recess 19 along the water stop bead 14.

  The door weather strip 10 according to claim 3 is provided with a mounting bottom surface portion 10a attached to a mounting portion 1a of a door frame 1 of an automobile, a trunk portion 12 located in the center portion, and a position on the indoor side of the trunk portion 12. A hollow seal portion 13 that elastically contacts the body panel, a rear rib 11 that is positioned outside the body portion 12 and elastically contacts the door frame 1, and is provided between the mounting bottom surface portion 10 a and the rear rib 11. And a water stop bead 14 that elastically contacts the door frame 1.

  And in the attachment surface of the fin part F attached to the corner part C of the said door frame 1, it has the protrusion height which elastically contacts the said door frame 1 in the inner peripheral side of the corner part F1, and the said back rib 11 horizontal A wall portion 17 having a length that forms a discharge recess 19 between the lower end portion and the water stop bead 14 is formed in the fin portion F. The outer side of the clip hole H is formed by integral molding.

  Thereby, the intrusion water B that has entered from the gap G between the corner portion C of the door frame 1 and the back rib 11 can be blocked by the wall portion 17 provided in the fin portion F.

In addition to the structure of claim 3, the door weather strip 10 according to claim 4 is a back surface in which intrusion water B that has entered from between the corner portion of the door frame 1 and the fin portion F is provided in the fin portion F. The water stop bead 14 prevents the intrusion water B from being discharged from the discharge groove 18 formed between the lower end of the rib 11 vertical part and the water stop bead 14 and over the wall 17. Then, the water is discharged from the discharge recess 19 along the water stop bead 14 to the outside of the vehicle.

  The door weather strip 10 according to claim 1 has a protruding height that elastically contacts the door frame 1 on the inner peripheral side of the corner portion F1 on the mounting surface of the fin portion F attached to the corner portion C of the door frame 1. Since the wall portion 17 having a length that reaches the water stop bead 14 at the lower end portion is provided by integral molding while continuously hanging from the horizontal portion of the rear rib 11, the corner portion C and the fin portion F of the door frame 1 are provided. The intruding water B that has entered from the gap G with the rear rib 11 can be blocked by the wall portion 17.

The door weather strip 10 according to claim 2 passes between the wall portion 17 and the vertical portion of the back rib 11 and between the lower end portion of the vertical portion of the back rib 11 provided in the fin portion F and the water stop bead 14. It can be discharged out of the vehicle from the discharge groove portion 18 formed in. Further, since the pressure is reduced by the wall portion 17 even at the time of high water pressure washing, even if the intruding water B over the wall portion 17 does not get over the water stop bead 14, it can be discharged out of the vehicle from the discharge recess 19. it can.

  Accordingly, it is possible to reliably prevent the intrusion water B from entering the room. Further, the intruding water B is dammed by the wall portion 17 and discharged from the discharge groove portion 18 formed by the vertical portion of the back rib 11, and the water over the wall portion 17 is dammed by the water stop bead 14 and the wall portion 17. Since the water is discharged from the discharge concave portion 19 formed by the water stop rib 14 and the intrusion into the room is prevented, it is not necessary to provide the ept sealer 16 which has been conventionally required. Therefore, it is not necessary to separately mold the eptosealer 16 and attach it with a double-sided adhesive tape, so that productivity can be improved.

  Moreover, since this wall part 17 is provided in the attachment surface (surface which opposes the door frame 1) of the fin part F, after attaching to the door frame 1, it is not visible from either the vehicle exterior side or the indoor side. Therefore, the appearance can be kept good.

  Similarly to the invention according to claim 1 or 2, the door weather strip 10 according to claim 3 or 4 can surely prevent the intrusion water B from entering the room, and can improve productivity. And maintain good appearance.

  Further, since the wall portion 17 is provided on the outer peripheral side of the clip hole H formed in the fin portion F, the intrusion water B enters the clip hole H and accumulates inside the weather strip, and deteriorates the weather strip. Do not cause problems.

  An embodiment of a door weather strip 10 according to the present invention is shown in FIGS. 1, 11 and 12. This is attached to a mounting portion 1a formed with a bottom surface portion 10a for mounting on an outer peripheral end portion of a door frame 1 of a left front door of an automobile, and includes a body portion 12, a hollow seal portion 13, a back rib 11, and a water stop bead. 14.

  The trunk | drum 12 is a solid thing located in the approximate center part of a weather strip. The hollow seal portion 13 is located on the indoor side of the body portion 12 and elastically contacts the body panel to seal between the body panel and the door frame 1. The back rib 11 is located on the vehicle exterior side of the trunk portion 12 and elastically contacts the door frame 1. The water stop bead 14 is connected to the vehicle outer wall surface of the body portion 12, is located between the mounting bottom surface portion 10 a and the rear rib 11, and is located on the inner peripheral side from the portion where the rear rib 11 of the door frame 1 is elastically contacted. Elastic contact. Further, the door weather strip 10 includes a seal lip 15 that elastically contacts the door opening edge of the body panel on the roof side.

  And, in the mounting surface (surface facing the door frame 1) of the fin portion F attached to the corner portion C of the door frame 1 (in this embodiment, the corner portion on the rear side of the front door), the inner periphery of the corner portion F1 The wall 17 is provided on the side (front side) by integral molding. The wall portion 17 has a protruding height that elastically contacts the door frame 1, and continuously hangs down from the horizontal portion of the back rib 11 having a substantially inverted L shape in the fin portion F, and the lower end portion stops. It is close to the water bead 14 and has a length that forms a discharge recess 19 with the water stop bead 14. In addition, the part (including fin part F) attached to the corner part C of this weather strip is formed by mold forming, and the part attached to the straight part S is formed by extrusion molding. In the triangle mark shown in FIG. 11, the white side of the extrusion-molded part is black and the side of the mold-formed part is shown.

  As a result, most of the intrusion water B that has entered from between the corner portion C and the fin portion F of the door frame 1 is allowed to pass between the vertical portion of the back rib 11 having a substantially inverted L shape and the wall portion 17. Thus, it can be discharged from the discharge groove 18 to the outside of the vehicle. Further, the slight intrusion water B that has passed over the wall portion 17 generated at the time of the high water pressure washing car flows down along the water stop bead 14 and is formed between the water stop bead 14 and the lower end portion of the wall portion 17. It can be discharged from the recess 19 to the outside of the vehicle. Thereby, it is possible to prevent the intrusion water B from entering the room. In addition, the discharge groove part 18 does not provide the lower end part of the back rib 11 perpendicular | vertical part until it reaches the water stop bead 14, but is formed by the recessed part formed between both by it.

  In this way, the intrusion water B is discharged outside the vehicle at two locations, between the wall portion 17 and the back rib 11 (discharge groove portion 18) and between the wall portion 17 and the water stop bead 14 (discharge recess 19). This eliminates the need for an ept sealer that had to be molded separately and attached. Thereby, productivity can be improved significantly.

  Moreover, since this wall part 17 is provided in the attachment surface (surface which opposes the door frame 1) of the fin part F, after attaching to the door frame 1, either the vehicle exterior side, the indoor side, or other than that Is not even visible. Therefore, a good appearance can be ensured.

  In the present embodiment, the wall portion 17 is provided on the outer peripheral side (rear side) of the clip hole H formed in the fin portion F. This prevents the intrusion water B from entering the clip hole H and accumulating inside the weather strip, thereby causing problems such as deterioration of the weather strip.
