  Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the embodiments for carrying out the invention described later.

According to the door weather strip according to claim 1 of the present invention, a rib is formed by providing a seal bead or a lip at the outer end of the vehicle in contact with the door sash of the mounting base of the upper extrusion molding portion, and molding is performed. In this section, the ribs are gradually moved in the outer peripheral direction (periphery direction of the door edge) and connected to the back lip of the lower extrusion part to form a series of ribs from the upper extrusion part to the lower extrusion part. The water that has entered between the rear lip of the molding part and the rib flows downward, and is discharged out of the vehicle along the outside of the rib. Therefore, even if the vehicle is designed to have a large angle between the upper extrusion part and the lower extrusion part in a side view, it is difficult for water to flow between the mounting base and the door sash, and the inside and outside of the vehicle can be reliably sealed. it can.
Therefore, since the sealing function can be secured without using any foamed sealing material, the manufacturing cost can be reduced. In addition, the manufacturing time can be shortened because there is no need to manually apply the foam seal material.

Further, according to the door weather strip according to claim 2, the foam sealing material is made of a high soft material between the rear end lip and the rear end lip of the part that contacts the door sash of the mounting base of the molded part connected by molding. Since a rib is formed by providing a seal bead or a lip at the outer end of the vehicle at the part that contacts the door sash of the mounting base of the upper extruded part, it is formed between the mounting base and the door sash. In the portion where water easily flows, double sealing can be performed by the foamed sealing material and the rib.
Furthermore, in the mold forming part, the ribs were gradually moved in the outer peripheral direction (periphery direction of the door edge) and connected to the back lip of the lower extrusion part to form a series of ribs from the upper extrusion part to the lower extrusion part. Therefore, the water that has entered between the back lip of the upper extrusion molding part and the high soft sponge material flows downward, and is discharged out of the vehicle along the outside of the rib. Therefore, even if the vehicle is designed to have a large angle between the upper extrusion part and the lower extrusion part in a side view, it is difficult for water to flow between the mounting base and the door sash, and the inside and outside of the vehicle can be reliably sealed. it can.

  Further, according to the door weather strip of the third aspect, in addition to the function and effect of the invention of the first or second aspect, the back lip of the mold forming part continuously provided from the back lip of the upper extrusion part is molded. Since it disappeared in the molding part, the water that has entered between the back lip and the foamed sealing material can be quickly discharged out of the vehicle from the end of the back lip. Therefore, a situation where water overflows and enters the vehicle is less likely to occur.

  Further, according to the door weather strip of the fourth aspect, in addition to the function and effect of the invention of the second or third aspect, the lower end of the foam seal material is placed in the molded part, so that the upper extrusion part, the lower extrusion part The amount of the foamed sealing material, which is inferior in installation reproducibility than the material of the molded part and the molded part, is reduced, and the sealing performance can be improved.

  According to the door weather strip of the fifth aspect, in addition to the function and effect of the invention of the second to fourth aspects, the foam sealing material is disposed below the end of the back lip lost in the molding part. Since the lower end is located, the sealing function by the foam sealant is secured even if water falls down intensively, and the foam seal is below the end of the back lip that has disappeared so that the water does not overflow. The sealing function can be secured without using any material. Therefore, the foamed sealing material can be functionally installed and the amount of use can be reduced, so that the manufacturing cost can be reduced without sacrificing the sealing function of the door weather strip.

(First embodiment)
A door weather strip according to a first embodiment of the present invention will be described with reference to FIGS. 1, 2, 5, and 6. In addition, the same symbol is attached | subjected to the same part as what was shown in the prior art example.

As shown in FIG. 5, the door weather strip according to the embodiment of the present invention has a gap with the body when the doors 1 and 2 are closed along the peripheral edges of the door sashes 3 and 4 of the front door 1 and the rear door 2 of the automobile. Installed to seal.
As shown in FIGS. 1 and 6, the weather strip 6 of the rear door 2 includes an upper extrusion portion 7 attached to the roof side of the door 2 and a lower extrusion portion 8 attached to the lower side of the door 2. It is formed by mold forming connection at the corner portion X. The hatched lines in FIG. 6 indicate the mold part 9 that connects the upper extrusion part 7 and the lower extrusion part 8 by molding. Moreover, in FIG. 1, the black side of the two black and white triangular marks described therein is the mold forming part 9, and the white side is the extrusion part (upper extrusion part 7 and lower extrusion part 8).

  Each of the upper extrusion part 7, the lower extrusion part 8, and the mold part 9 includes an attachment base 11, a hollow seal part 12, a sub seal part 13, and a back lip 14.

The attachment base 11 extends substantially parallel to the door sash 4 and is attached along the door sash 4.
The hollow seal portion 12 is a hollow main seal that is integrally formed with the mounting base portion 11 on the vehicle inner side of the mounting base portion 11 and elastically contacts the door opening peripheral edge of the body panel when the door is closed to seal the inside and outside of the vehicle.
The sub seal portion 13 protrudes from the attachment base portion 11 on the vehicle outer side of the attachment base portion 11 and outward from the hollow seal portion 12. Similar to the hollow seal portion 12, the sub seal portion 13 elastically contacts the door opening peripheral portion of the body panel when the door is closed, and assists the sealing function of the hollow seal portion 12.
The rear lip 14 protrudes from the mounting base 11 on the vehicle outer side of the mounting base 11 and on the mounting base 11 side from the sub seal portion 13. In a state where the attachment base 11 is attached to the door sash 4, the back lip 14 comes into elastic contact with the door sash 4.

  Further, a fin piece 16 extends from between the sub-seal portion 13 and the back lip 14 to the outer periphery of the upper extrusion molding portion 7 and the mounting base portion 11 of the die molding portion 9 and is attached to the door sash 4 via the clip 15. ing.

Further, a high soft sponge material 17 is provided between the vehicle outer side end portion 11 a of the portion that contacts the door sash 4 of the mounting base portion 11 of the upper extrusion molding portion 7 and the rear lip 14.
The high soft sponge material 17 here is a highly foamed sponge material, specifically, a sponge material foamed to have a specific gravity of 0.05 to 0.4.

Further, a separate foam sealing material 38 having an excellent sealing function is provided between the vehicle outer side end portion 11a of the mounting base portion 11 of the mold forming portion 9 that contacts the door sash 4 and the rear lip 14, and a high soft sponge. It continues from the material 17. This means that the foamed sealing material 38 is mainly disposed in the mold forming portion 9, and the continuous connection (connection) between the high soft sponge material 17 and the foamed sealing material 38 is an upper extrusion molding. Part 7 is done.
Note that unlike the extrusion molding unit 7, the foam sealing material 38 cannot be molded simultaneously with the molding of the door weather strip 6 unlike the extrusion molding unit 7. It is set by adhering to the mounting base 11 made by finishing.
Here, as a typical example of the foam sealing material 38, there is a product “Epto Sealer (registered trademark)” manufactured by Nitto Denko Corporation. The foam structure of the EPDM foam sealing material 38 includes a closed cell type in which bubbles are not in contact with each other and a semi-independent semi-open cell type in which bubbles are in contact with each other and are connected to each other.

  In the mold forming part 9, the back lip 14 of the upper extrusion part 7 is connected to the back lip 14 of the mold forming part 9, and a series of first ribs 14 are formed.

A seal bead (which may be a lip) is provided on the vehicle outer side end portion 11a of the portion of the upper extrusion molding portion 7 that is in contact with the door sash 4 of the mounting base portion 11, and the second rib 31 is formed. . That is, the second rib 31, the high soft sponge material 17, and the back lip 14 are arranged in this part in order toward the vehicle exterior.
Moreover, in the mold forming part 9, as it goes from the upper extrusion part 7 to the lower extrusion part 8, the second rib 31 is gradually moved from the change start point 31a in the outer peripheral direction (outer peripheral direction of the door edge), and finally Is connected to the back lip 14 of the lower extrusion molding portion 8 at the change end point 31b, so that a series of second ribs 31 are formed from the upper extrusion molding portion 7 to the lower extrusion molding portion 8.

  That is, the position where the second rib 31 is disposed in the upper extrusion part 7 and the position where the second rib 31 (the back lip 14 of the lower extrusion part 8) is disposed in the lower extrusion part 8 are cross sections. In this case, the relationship is twisted by approximately 90 °.

Further, the back lip 14 (first rib 14) of the mold forming part 9 continuously provided from the back lip 14 of the upper extrusion part 7 disappears in the mold forming part 9.
Then, the change end point 31b of the second rib 31 is positioned below the end 14a of the first rib 14, and the lower end 38a of the foam sealant 38 is positioned below the change end point 31b of the second rib 31. ing. Note that the lower end 38 a of the foam seal material 38 is positioned in the mold forming portion 9.

According to the door weather strip 6 configured as described above, the second rib 31 is formed by providing the seal bead on the vehicle outer side end portion 11a of the portion of the mounting base portion 11 of the upper extrusion molding portion 7 that is in contact with the door sash 4. At the same time, in the mold part 9, the second rib 31 is gradually moved in the outer peripheral direction (periphery direction of the door edge) and connected to the back lip 14 of the lower extrusion part 8 to be connected from the upper extrusion part 7 to the lower extrusion part. Since a series of second ribs 31 are formed up to 8, the water W that has entered between the back lip 14 of the upper extruded portion 7 and the high soft sponge material 17 is downward as shown by the broken lines in FIGS. Is discharged outside the vehicle along the outside of the second rib 31. Therefore, even if the vehicle has a design in which the angle θ formed by the upper extrusion portion 7 and the lower extrusion portion 8 is large when viewed from the side, the water W hardly flows between the mounting base portion 11 and the door sash 4, so The inside and outside can be sealed.
Of course, even if the door weather strip 6 according to the present embodiment is used in a vehicle having a general angle θ formed by the upper extrusion portion 7 and the lower extrusion portion 8, the inside and outside of the vehicle can be reliably sealed. Can do.

  Further, since the first rib 14 has disappeared in the mold forming part 9, the water W that has entered between the first rib 14 and the foamed sealing material 38 is quickly discharged from the end 14a of the first rib 14 to the outside of the vehicle. can do. Therefore, the situation where the water W overflows and enters the vehicle is less likely to occur.

Furthermore, since the lower end 38a of the foam seal material 38 is positioned below the change end point 31b of the second rib 31, the location where the water tends to fall down due to concentration of water is the foam seal material 38 and the second rib 31. Double sealing is possible, and a sealing function is ensured. On the other hand, in a place where it is difficult to overflow below the change end point 31b of the second rib 31, a sealing function can be secured without setting the foamed sealing material 38, and the manufacturing cost can be reduced by the amount used. In other words, since the foamed sealing material 38 can be functionally installed and the amount of use can be reduced, the manufacturing cost can be reduced without sacrificing the sealing function of the door weather strip 6.
Moreover, since the amount of the foamed sealing material 38 that is inferior to the material of the upper extrusion molding part 7, the lower extrusion molding part 8 and the molding part 9 is reduced, the sealing performance can be improved.
Here, if the change start point 31a and the change end point 31b of the second rib 31 are shifted and molded toward the upper extrusion part 7 in the mold part 9, the amount of use of the foam sealant 38 can be further reduced.
Therefore, in the door weather strip 6 according to the conventional example, the use amount of the foam sealing material 38 is increased in the door weather strip 6 according to the present embodiment as compared with the case where the ept sealer 18 must be extended to the waist portion 2a of the door 2. Is much less.

(Second embodiment)
Next, with reference to FIG. 3 and FIG. 4, the door weather strip 6 which concerns on 2nd embodiment of this invention is demonstrated. In addition, the same code | symbol was attached | subjected to the same part as 1st embodiment.
The difference of this embodiment from the first embodiment is that no foamed sealing material 38 is used, and the other components are the same as those of the first embodiment.

As described above, even when the foam seal material 38 is not used at all, the second rib 31 is provided with a seal bead on the vehicle outer side end portion 11a of the attachment base portion 11 of the upper extrusion molding portion 7 in contact with the door sash 4. In the mold forming part 9, the second rib 31 is gradually moved in the outer peripheral direction (periphery direction of the door edge) and is connected to the back lip 14 of the lower extrusion part 8 to be connected to the lower part from the upper extrusion part 7. Since the series of second ribs 31 is formed up to the extrusion molding part 8, the water W that has entered between the back lip 14 of the upper extrusion molding part 7 and the second ribs 31 as shown by the broken lines in FIGS. Is discharged downward along the outer side of the second rib 31. Therefore, in a vehicle having a design in which the angle θ formed by the upper extrusion portion 7 and the lower extrusion portion 8 is large in a side view, like the door weather strip 6 according to the first embodiment, the foam sealing material 38 and the second rib 31 are used. Therefore, the water W hardly flows between the mounting base 11 and the door sash 4 as compared with the door weather strip 6 according to the conventional example without double sealing, and the inside and outside of the vehicle can be reliably sealed.
According to this, since the sealing function can be ensured without using any foamed sealing material 38, the manufacturing cost can be reduced. In addition, since the step of manually attaching the foam seal material 38 is eliminated, the manufacturing time can be shortened.

  In addition, in 1st and 2nd embodiment, although the 1st rib 14 is lose | disappeared in the shaping | molding part 9, it is not restricted to this, It is made to lose | disappear after extending to the 2nd extrusion molding part 8. Also good.

  In addition, it is desirable to position the change end point 31b of the second rib 31 below the end 14a of the first rib 14, but since the drain end also drains from the end 14a of the first rib 14, the end 14a of the first rib 14 The change end point 31b of the second rib 31 may be positioned above the position.

  Moreover, although the example which applied the door weather strip 6 to the corner part of the rear door 2 was shown, it is not restricted to this, It can apply also to the corner part of the front door 1, Even in this, it is surely inside and outside the vehicle Can be sealed.

  In the first embodiment, the lower end 38a of the foam sealing material 38 is positioned below the end 14a of the first rib 14. However, the present invention is not limited to this, and the end 14a of the first rib 14 is not limited thereto. The lower end 38a of the foamed sealing material 38 may be positioned further upward.

In addition, it is desirable that the lower end 38a of the foam sealing material 38 is located below the change end point 31b of the second rib 31, and the portion that is likely to overflow is preferably sealed twice with the foam sealing material 38 and the second rib 31. Even if the lower end 38a of the sealing material 38 is located above the change end point 31b of the second rib 31, the second rib 31 can be sealed alone as in the door weather strip 6 according to the second embodiment.
On the contrary, the lower end 38 a of the foam seal material 38 may be extended to the second extruded portion 8. Thus, even if the foamed sealing material 38 is extended, it is not necessary to extend to the waist portion 2a of the door 2, so that the cost is lower than that of the door weather strip 6 according to the conventional example.
