Description

  The present invention relates to a weather strip that is attached along the periphery of an opening formed in a vehicle body.

  Generally, a weather strip is provided at the periphery of an opening formed in a vehicle body such as an automobile. The weather strip is attached to a flange portion provided along the periphery of the opening, and has a substantially U-shaped cross section including an inner peripheral side wall portion, an outer peripheral side wall portion, and a connecting portion connecting both side wall portions. And a hollow seal portion protruding from the trim portion and having a hollow portion. When the opening / closing member that opens and closes the opening is closed, the hollow seal portion is brought into pressure contact with the peripheral edge of the opening / closing member, thereby sealing between the vehicle body and the opening / closing member.

  By the way, when the opening / closing member is closed, a gap having a V-shaped cross section called “triangular gap” is formed between the opening / closing member and the hollow seal portion deformed so as to be crushed by being pressed against the opening / closing member. The Rukoto. For this reason, when a hollow seal part and an opening-and-closing member contact | abut in the direction which cross | intersects with respect to a perpendicular direction, we are anxious about rain water, washing water, etc. accumulating in this triangular gap. In this case, when the opening / closing member is opened, there is a possibility that water accumulated in the triangular gap may enter the room.

  In contrast, the triangular gap formed between the hollow seal portion and the opening / closing member is filled, and the open / close state in the closed state is projected to the outside of the vehicle and the outer peripheral side of the opening portion with respect to the distal end portion of the hollow seal portion. It is conceivable to provide a tip lip that presses against the member. However, in this case, there is a concern that a triangular gap is formed between the tip lip pressed against the opening / closing member and the hollow seal portion, and water is collected in the triangular gap, and when the opening / closing member is opened, the hollow seal portion is When returning to its original shape by its own elastic force, there is a risk that water accumulated in the triangular gap may enter the room.

  In addition, a lip portion extending from the hollow seal portion to the vehicle exterior side is provided at a position below the contact portion (tip lip) with the opening / closing member of the hollow seal portion, and when the opening / closing member is opened, the tip lip and the hollow seal are provided. When water accumulated in the triangular gap formed between the two parts flows downward, the lip part receives the water and suppresses intrusion into the room (for example, see Patent Document 1). .

Japanese Utility Model Publication No. 6-49225

  However, even if the lower lip portion is provided as described in Patent Document 1, water still accumulates in the triangular gap of the tip lip, so that when the opening and closing member is opened, the water accumulated in the triangular gap enters the room. There is a concern that problems such as intrusion cannot be completely resolved. Furthermore, depending on the case, when the opening / closing member is closed, there is a concern that water accumulated in the gap between the lower lip portion and the hollow seal portion may enter the indoor side. In addition, there is a concern that the presence of the lower lip portion may require a larger force when closing the opening / closing member (becomes difficult to close).

  The present invention has been made to solve the above-described problems, and the object thereof is to more reliably prevent the water that has accumulated at the contact portion between the hollow seal portion and the opening / closing member from entering the chamber. It is to provide a weather strip that can be used.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A connecting portion that is provided along the periphery of the opening of the vehicle body and that is attached to a flange portion extending in a direction intersecting the vertical direction, and connects the outer peripheral side wall portion, the inner peripheral side wall portion, and both side wall portions; A trim portion having a substantially U-shaped cross section,
A hollow seal portion that protrudes outward from the connecting portion along the extending direction of the flange portion and that is pressed against the peripheral edge portion of the opening and closing member when the opening and closing member that opens and closes the opening portion is closed. ,
The hollow seal portion includes a distal end lip that projects from the distal end in the projecting direction toward the vehicle outer side and the outer peripheral side of the opening, and contacts the opening and closing member when the opening and closing member is closed,
At least the upper side portion attached along the upper edge portion of the opening portion is adjacent to or adjacent to the outer peripheral side surface of the opening portion of the tip lip with respect to the hollow seal portion, and the inner peripheral surface of the hollow seal portion. A drain hole is formed to communicate the side and the outer peripheral surface side,
The lower side part attached along the lower edge part of the opening part has an inner periphery of the hollow seal part at a position located on the lowermost side of the inner peripheral surface of the hollow seal part with respect to the hollow seal part. A weather strip, wherein a discharge hole is formed to communicate the surface side and the outer peripheral surface side.

  According to the means 1, a drain hole is formed in the upper side portion of the weather strip adjacent to or close to the outer peripheral side surface of the opening portion of the tip lip so as to communicate the inner peripheral surface side and the outer peripheral surface side of the hollow seal portion. Has been. Therefore, when the open / close member is closed, if water enters a triangular gap formed at the contact portion (between the tip lip and the hollow seal portion) between the open / close member and the hollow seal portion, It is guided to the inner peripheral side (hollow part) of the hollow seal part through the drain hole. Therefore, water does not collect in the triangular gap, and it is possible to more reliably prevent the water collected in the triangular gap from entering the room when the opening / closing member is opened.

  Further, a discharge hole is formed in the lower side portion of the weather strip so that the inner peripheral surface side and the outer peripheral surface side of the hollow seal portion communicate with each other. The discharge hole allows the hollow seal portion to pass through the drain hole. The water guided to the inner peripheral side can be discharged to the outside at the lower edge of the opening. In particular, since the discharge hole is formed in the lowermost portion of the inner peripheral surface of the hollow seal portion, it is possible to suppress a situation in which water remains in the hollow seal portion.

  Further, a technique for forming an air vent hole in the hollow seal portion has been conventionally known in order to make the hollow seal portion easy to follow and deform and to reduce the force required to close the opening / closing member as much as possible (to make it easy to close). However, in this means, the same effect as the case where the air vent hole is provided by forming the water drain hole is exhibited. Therefore, the force required for closing the opening / closing member can be reduced as much as possible while suppressing an increase in the number of manufacturing steps.

  In addition, the sealing performance can be enhanced by providing the tip lip in the hollow seal portion. In particular, in this means, the drainage hole is formed in the vicinity of the contact portion of the hollow seal portion with the opening / closing member. However, the presence of the tip lip can ensure the pressure contact area, and the drainage hole is formed on the tip side in the protruding direction of the hollow seal portion. It is possible to suppress the deviation itself. For this reason, it is possible to reliably prevent a situation in which the sealing performance is deteriorated due to the formation of the drain hole. Furthermore, the water flowing into the contact portion between the hollow seal portion and the opening / closing member can be guided to the drain hole side by the tip lip. In addition, the tip lip can hide at least a part of the drainage hole formed adjacent to or close to the outer peripheral side surface of the opening of the tip lip from the person who opens and closes the opening / closing member. Therefore, it is possible to suppress a situation in which the designability is deteriorated by visually recognizing the drain hole.

Mean 2. An extruded part provided so that one end and the other end in the longitudinal direction are located at the lower edge of the opening;

  According to the means 2, by using the core hole formed to mold the inner peripheral surface of the hollow seal part of the mold forming part as the discharge hole, the discharge for discharging all the water in the hollow seal part It is not necessary to form a hole separately, and an increase in the manufacturing process can be suppressed. In addition, by forming the discharge hole in the extrusion molding part, the formation width of the molding part can be shortened as much as possible, and the mold can be downsized, the cost can be reduced, and the design can be improved.

  Means 3. The weather strip according to means 1 or 2, wherein the drain holes are formed at predetermined intervals in the entire longitudinal direction.

  According to the means 3, since the water drainage holes are formed at predetermined intervals in the entire longitudinal direction of the weather strip, the hollow seal portion is formed over the entire circumference of the weather strip without separately forming the air vent holes. The effect of making it easier to follow and deform is achieved. Therefore, the effect of reducing the force required to close the opening / closing member as much as possible while suppressing an increase in manufacturing man-hours and the like is more reliably achieved.

  Even when a large amount of water flows into the hollow seal part from the drain hole formed in the upper side of the weather strip, and the drain hole cannot catch up with such water, the water strip It can also be discharged to the outside through a drain hole formed in the lower side of the. As described above, since the drain hole is formed on the outer peripheral side of the opening portion with respect to the tip lip, even if water is discharged from the drain hole, the water does not enter the room.

  Means 4. The weather strip according to any one of means 1 to 3, wherein the drain hole has a diameter of 5 mm or more.

  According to the means 4, since the diameter of the drain hole is 5 mm or more, it is possible to avoid a situation in which water does not suitably escape from the drain hole due to surface tension. Therefore, it is possible to drain water reliably and relatively smoothly by forming the drain hole.

And the weather strip 5 is attached to the peripheral part of the opening part 4 by relatively fitting the flange part 33 inside the trim part 11. Further, when the luggage door 2 is closed, the hollow seal portion 15 is pressed against the peripheral edge portion of the luggage door 2 at the portion including the tip lip 41 and is crushed and deformed (see the two-dot chain line in FIG. 3). 2 and the vehicle body 3 are sealed.

  As shown in FIG. 1, the rear ceiling portion of the automobile 1 of the present embodiment is inclined downward toward the rear, and the luggage room provided at the rear portion of the automobile 1 is in accordance with the shape of the ceiling portion. In addition, it opens obliquely toward the rear, and also opens rearward so that luggage can be easily taken in and out. In other words, the opening 4 has an upper edge extending in the vehicle width direction, a side edge extending obliquely downward and downward from both ends of the upper edge, and a lower side from the rear end of each side edge. A vertical edge portion extending and a lower edge portion extending so as to connect lower end portions of both vertical edge portions are provided. However, in the present embodiment, the vertical edge portion does not extend in the vertical direction, but extends slightly inclined backward toward the lower side. Hereinafter, in the opening 4, a portion surrounded by the upper edge and both side edges is referred to as an upper opening surface 4 a, and a portion surrounded by the lower edge and both vertical edges is referred to as a lower opening surface 4 b.

  Moreover, the flange part 33 formed along the peripheral part of the opening part 4 is extended perpendicularly | vertically with respect to the corresponding opening surfaces 4a and 4b toward the vehicle outer side. More specifically, the portion of the flange portion 33 corresponding to the upper edge portion of the opening portion 4 extends upward in a direction slightly inclined backward (see FIGS. 3 and 4), and the opening portion 4. The portion corresponding to the lower edge portion of the portion extends in a direction slightly inclined upward (see FIG. 6). In the present embodiment, the weather strip 5 is attached to the flange portion 33 so that the mold forming portion 7 is positioned at the center of the lower edge portion of the opening 4.

  Further, the hollow seal portion 15 projects outward from the connecting portion 14 of the trim portion 11 along the extending direction of the corresponding flange portion 33. That is, the portion of the weather strip 5 corresponding to the upper edge portion of the opening 4 (hereinafter referred to as the upper side portion 5a) is inclined slightly downward from the connecting portion 14 of the trim portion 11 upward. (Refer to FIGS. 3 and 4), and a portion corresponding to the lower edge portion of the opening 4 (hereinafter referred to as the lower side portion 5b) is inclined slightly upward from the connecting portion 14 of the trim portion 11 toward the rear. It protrudes in the direction (see FIG. 6). As a result, the hollow seal portion 15 has a luggage door perpendicular to each of the opening surfaces 4a and 4b (in the extending direction of the flange portion 33) at a portion including the tip lip 41 provided at the tip portion in the protruding direction. 2 and pressure contact.

  Further, the trim portion 11 is provided with an inner peripheral holding lip 21 extending from the inner side surface of the inner peripheral side wall portion 12 and an outer peripheral side holding lip 22 extending from the inner side surface of the outer peripheral side wall portion 13. ing. Two inner peripheral holding lips 21 and two outer peripheral holding lips 22 are provided at a predetermined distance in the direction in which the trim portion 11 is attached to the flange portion 33. Then, by relatively fitting the flange portion 33 inside the trim portion 11, the inner peripheral holding lip 21 and the outer peripheral holding lip 22 are pressed against the flange portion 33, and the elastic force by the holding lips 21, 22, etc. The weather strip 5 is attached based on the above.

  Furthermore, the extrusion molding part 6 extends from the inner peripheral side wall part 12 to the inner peripheral side of the opening part 4 and covers a design lip 23 that covers the edge of the interior member 29, and the outer peripheral side wall part 13 to the outer periphery of the opening part 4. A draining lip 24 extending to the side and abutting a panel (outer panel) constituting the automobile body 3; a sub lip 25 extending from the tip of the outer peripheral side wall 13 to the inner peripheral side of the opening 4 and abutting the outer panel; It has.

  In this embodiment, the trim part 11 and the holding lips 21 and 22 are basically made of solid EPDM (ethylene-propylene-diene copolymer rubber), and have a hollow seal part 15, a design lip 23, a draining lip 24, The sub lip 25 is made of sponge EPDM. However, the outer peripheral side holding lip 22 on the base side of the flange portion 33 is made of sponge EPDM.

  Further, the extruded portion 6 includes a seal protrusion 27 having a substantially semicircular cross section that protrudes from the inner surface of the connecting portion 14 to the inside of the trim portion 11. When the weather strip 5 is attached to the flange portion 33, the seal projection 27 and the leading edge of the flange portion 33 are in contact with each other. Due to the presence of the seal protrusion 27 and the draining lip 24 and the sub lip 25, it is possible to more reliably prevent a situation in which rainwater or the like enters the indoor side (luggage room) from between the trim portion 11 and the flange portion 33. be able to.

  Note that the molded part 7 also has a cross-sectional shape substantially the same as that of the extruded part 6 and includes a trim part 11 and a hollow seal part 15.

  Now, as shown in FIG. 4, in the present embodiment, with respect to the hollow seal portion 15 of the extrusion molding portion 6, the inner peripheral surface of the hollow seal portion 15 is adjacent to the outer peripheral side surface of the opening portion 4 of the tip lip 41. A drain hole 42 is formed to communicate with the outer peripheral surface. The drain holes 42 are formed at predetermined intervals (in this example, at a pitch of 100 mm) over the entire longitudinal direction of the extruded portion 6. Moreover, the diameter of the drain hole 42 is 5 mm.

  As described above, in the present embodiment, the hollow seal portion 15 of the upper side portion 5a of the weather strip 5 protrudes upward and rearward along the extending direction of the flange portion 33 from the trim portion 11, As shown by the two-dot chain line in FIG. 4, when the luggage door 2 is closed, the bottom lip 41 that is in pressure contact with the luggage door 2 and the hollow seal portion 15 that is crushed and deformed by pressure contact with the luggage door 2 are A triangular gap (triangular gap 43) that is concave is formed. And since the drain hole 42 is formed in the site | part which comprises this triangular gap 43 among the hollow seal parts 15, the water (rain water, washing water, etc.) which flowed into this triangular gap 43 is the drain hole 42. It will be guided to the inner peripheral side (hollow part 15a) of the hollow seal part 15 via.

  Further, as shown in FIGS. 5 and 6, in the lower side portion 5 b of the weather strip 5, the inner periphery of the hollow seal portion 15 of the mold forming portion 7 is located in the vicinity of the mold forming portion 7 in the extrusion forming portion 6. A core punching hole 44 for punching a core mold for molding the surface is formed. The core punching hole 44 is located at the lowermost position of the inner peripheral surface of the hollow seal portion 15 of the extruded portion 6 (lower side portion 5b) in the state of being attached to the flange portion 33. The inner circumferential surface and the outer circumferential surface are formed to communicate with each other. For this reason, in this embodiment, the water guided to the hollow portion 15a through the drain hole 42 is discharged from the core hole 44 to the outside. That is, in the present embodiment, the core hole 44 constitutes a discharge hole. Further, the core hole 44 has a long hole shape, and the formation width in the longitudinal direction of the weather strip 5 is 15 mm, and the formation width in the circumferential direction of the hollow seal portion 15 is 3 mm.

  The formation width in the longitudinal direction of the weather strip 5 of the molded portion 7 of this embodiment is 5 mm for the hollow seal portion 15, the tip lip 41, the design lip 23, the drain lip 24, and the sub lip 25, and the trim portion. 11 and the holding lips 21 and 22 are 15 mm.

  As described above in detail, according to the present embodiment, the upper side portion 5a of the weather strip 5 is adjacent to the outer peripheral side surface of the opening 4 of the tip lip 41 and the inner peripheral surface side and the outer periphery of the hollow seal portion 15. A drain hole 42 is formed to communicate with the surface side. For this reason, when the luggage door 2 is closed, water enters the triangular gap 43 formed at the contact portion between the luggage door 2 and the hollow seal portion 15 (between the tip lip 41 and the hollow seal portion 15). The water is guided to the inner peripheral side (hollow portion 15a) of the hollow seal portion 15 through the drain hole 42. Therefore, water does not collect in the triangular gap 43, and it is possible to more reliably prevent the water collected in the triangular gap 43 from entering the room when the luggage door 2 is opened.

  Further, the lower side portion 5b of the weather strip 5 is formed with a core hole 44 as a discharge hole for communicating the inner peripheral surface side and the outer peripheral surface side of the hollow seal portion 15. With the core hole 44, the water guided to the hollow portion 15 a through the water hole 42 can be discharged to the outside at the lower edge of the opening 4. In particular, since the cored hole 44 is formed at the lowermost portion of the inner peripheral surface of the hollow seal portion 15, it is possible to suppress a situation in which water remains in the hollow portion 15a. .

  Further, by using the core hole 44 formed for molding the inner peripheral surface of the hollow seal portion 15 of the mold forming portion 7 as a discharge hole for discharging all the water in the hollow portion 15a, the discharge is performed. It is not necessary to form a hole separately, and an increase in the manufacturing process can be suppressed. In addition, by forming the cored hole 44 in the extruded part 6, the formation width of the molded part 7 can be shortened as much as possible, and the mold can be reduced in size, reduced in cost, improved in design, etc. Can do.

  In addition, the sealing performance can be enhanced by providing the tip lip 41 in the hollow seal portion 15. In particular, in this embodiment, since the drain hole 42 is formed in the vicinity of the contact portion of the hollow seal portion 15 with the luggage door 2, the position where the drain hole 42 is formed protrudes from the hollow seal portion 15 due to a manufacturing error or the like. However, the presence of the tip lip 41 can ensure the pressure contact area, and the water drainage hole 42 is formed in a hollow seal. It can be suppressed that the portion 15 is shifted to the front end side in the protruding direction. For this reason, it is possible to reliably prevent a situation in which the sealing performance is deteriorated due to the formation of the drain hole 42. Further, the water flowing into the contact portion between the hollow seal portion 15 and the luggage door 2 can be guided to the drain hole 42 side by the tip lip 41. Further, the tip lip 41 can hide at least a part of the drain hole 42 formed adjacent to or close to the outer peripheral side surface of the opening 4 of the tip lip 41 from those who open and close the luggage door 2. Therefore, it is possible to suppress a situation in which the designability is deteriorated by visually recognizing the drain hole 42.

  Further, in order to make the hollow seal portion 15 easier to follow and deform and to reduce the force required to close the luggage door 2 as much as possible (to make it easier to close), a technique for forming an air vent hole in the hollow seal portion 15 from the past. However, in this embodiment, the same effect as the case where the air vent hole is provided by forming the water drain hole 42 is exhibited. Therefore, the force required for closing the luggage door 2 can be reduced as much as possible while suppressing an increase in the number of manufacturing steps. In particular, in the present embodiment, since the drain holes 42 are formed at predetermined intervals over the entire length of the extruded portion 6, it is possible to extend over the entire circumference of the weather strip 5 without forming additional air vent holes. The effect of making the hollow seal portion 15 easy to follow and deform is exhibited. Therefore, such an effect is more reliably achieved.

  Further, even when a large amount of water flows into the hollow portion 15a from the drain hole 42 formed in the upper side portion 5a of the weather strip 5 and the drainage of the water cannot catch up with the core hole 44 alone, this is required. Water can also be discharged to the outside from a drain hole 42 formed in the lower side portion 5b (and the vertical side portion and the side portion) of the weather strip 5. Since the drain hole 42 is formed on the outer peripheral side of the opening 4 with respect to the tip lip 41 as described above, even if water is discharged from the drain hole 42, the water enters the room. There is no.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the said embodiment, although the drain hole 42 is formed for every predetermined space | interval over the longitudinal direction whole region of the weather strip 5 (extrusion molding part 6), it is not limited to such a structure in particular. It is sufficient that at least one drain hole 42 is formed in at least the upper side portion 5a of the weather strip 5. For example, drain holes 42 are formed at predetermined intervals along the longitudinal direction of the weather strip 5 at the upper side 5a of the weather strip 5 and at the corner formed by the upper side 5a and the side. In the portion where the drain hole 42 is not formed in the strip 5 (extrusion molding portion 6), the air vent hole having a smaller diameter (for example, 3 mm) than the drain hole 42 extends along the longitudinal direction of the weather strip 5. It may be formed at predetermined intervals. In the case of forming the air vent hole, the air vent hole is formed on the outer peripheral side of the opening 4 with respect to the tip lip 41 in the same manner as the water vent hole 42. That is, it is possible to reliably avoid a situation in which water guided from the drain hole 42 to the inner peripheral side of the hollow seal portion 15 enters the indoor side through the air vent hole.

  (B) In the said embodiment, although the diameter of the drain hole 42 is 5 mm, it is not limited to this structure in particular. However, if the diameter of the drain hole 42 is 3 mm or less, there is a concern that it is difficult for water to escape from the drain hole 42 due to surface tension or the like, so the diameter of the drain hole 42 is 4 mm or more. Is preferably 5 mm or more. On the other hand, even if the drain hole 42 is too large, there is a risk of causing a decrease in designability or a decrease in rigidity. Therefore, the diameter of the drain hole 42 is set to 10 mm or less, and further to 8 mm or less in order to suppress such problems. It is desirable that

  (C) In the above embodiment, the weather strip 5 is made of EPDM, but may be made of another material such as an olefinic thermoplastic elastomer (TPO). Moreover, in the said embodiment, although the trim part 11 and the holding lips 21 and 22 are comprised by solid EPDM, for example, it is more rigid than the hollow seal part 15 grade | etc. (The degree of foaming is low, and the hollow seal part 15 is made. It is good also as comprising by sponge EPDM (fine foaming material) whose density is larger than the material to comprise. In this case, the deformation of the trim portion 11 can be suppressed while reducing the weight, and the weather strip 5 can be assembled to the flange portion 33 in a stable state.
