Abstract
Description
[Technical Field]
[0001] The present invention relates to a drip weatherstrip that is attached to the door opening edge of a vehicle body having a hinged door, elastically contacts the door when the door is closed, and has a drip passage for conducting water. [Background technology]
[0002] As shown in FIG. 10, a known automobile 200 has a hinged door (front door) 201, and a drip weather strip 300 is provided on the vehicle body side facing the door 201 when the door 201 is closed (see, for example, Patent Document 1). As shown in Fig. 11, this drip weatherstrip 300 includes a seal portion 302 extending from a mounting base 301 attached to the body B side toward the door 201, and a drip lip 303 provided below the seal portion 302, with a first drip passage 304 formed from the base of the seal portion 302 to the body B side, and a second drip passage 305 formed between the seal portion 302 and the drip lip 303, and as shown in Fig. 12, the first drip passage 304 and the second drip passage 305 are communicated with each other by a communication portion 306. The communication portion 306 is formed on the body B side of a seal lip 307 which integrates the seal portion 302 and the drip lip 303.
[0003] According to this, by merging the water that has passed through the first drip passage 304 and the water that has passed through the second drip passage 305 at the communication part 306, the water that has passed through the second drip passage 305 flows toward the side edge seal, thereby preventing water droplets from falling at the end of the upper edge of the door 201. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 6067125 Summary of the Invention [Problem to be solved by the invention]
[0005] However, there is no description of how the water that has joined the communication section 306 is subsequently drained, and it is assumed that it will be drained directly downwards. However, since hinges H1 for the door 201 are provided above and below the door 201, if the water is drained directly downwards, there is a risk that the hinges H1 will get wet. If too much water gets on the hinge H1, it will cause rusting problems.
[0006] In response to this, it is conceivable to extend the drip weatherstrip 300 forward of the position of the hinge H1 so as to prevent the amount of water that gets on the hinge H1 from becoming too large. However, simply extending the drip weatherstrip 300 would require cutting (cutting off) the seal lip 307 from the tip 307a to the base 307b of the seal lip 307 directly above the hinge H1, as shown in Figure 13, due to the layout of the door 201 and the body B, as the door 201 interferes with the seal lip 307 when the door 201 is closed. More specifically, in the area directly above hinge H1, when door 201 is closed, seal lip 307 assumes a bent shape as shown by the dashed line, and when door 201 is subsequently opened, the tip of door 201 scratches the surface of seal lip 307 facing door 201, causing seal lip 307 to break or tear. This is not limited to the drip weatherstrip 300 shown in Figures 10 to 13, but is a common problem with drip weatherstrips generally installed along the front pillars (A-pillars) of automobiles with hinged doors.
[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a drip weather strip that minimizes the amount of water that is applied to door hinges and makes the hinges less susceptible to rust. [Means for solving the problem]

[0016] It should be noted that symbols in parentheses indicate corresponding elements or matters described in the drawings and in the detailed description to be described later. [Effects of the Invention]
[0017] According to the drip weatherstrip of the present invention, a first drip passage formed between the mounting portion and the main seal lip and capable of conducting water extends from a position opposite to the position directly above the rear of the door to a position directly above the door hinge or just before that position, and a second drip passage is provided that extends from a position below the front end of the first drip passage to a position forward of the position directly above the door hinge.Water falling from the front end of the first drip passage is received in the second drip passage and is then allowed to fall through the second drip passage to a position forward of the position directly above the door hinge, thereby reducing the amount of water that comes into contact with the door hinge and making the door hinge less susceptible to rust.
[0018] In addition, according to the present invention, the second drip passage is formed between an extension base that bends and extends forward from the mounting portion of the first drip passage and is located lower than the mounting portion, and an extension sub-lip that extends upward from the lower portion of the extension base, so that it can receive a sufficient amount of water and reduce the amount of water that gets on the door hinge.
[0019] In addition, according to the present invention, the inclination angle of the second drip passage relative to the horizontal plane on which the vehicle is placed is smaller than the inclination angle of the first drip passage relative to the horizontal plane on which the vehicle is placed, so that the set length of the second drip passage can be shortened.
[0020] Furthermore, according to the present invention, the main seal lip of the first drip passage is gradually shortened from just before the position directly above the door hinge and disappears at the position directly above the door hinge, so that when the door is closed, the door does not interfere with the main seal lip at the position directly above the door hinge. This improves the durability of the drip weatherstrip and does not particularly impair door closing performance.
[0021] Furthermore, according to the present invention, a third drip passage is provided that extends from the rear end position of the second drip passage to a position rearward of the position directly above the door hinge, and water that falls from the first drip passage and cannot be received by the second drip passage is collected and channeled into the second drip passage, thereby reducing the amount of water that enters the interior of the vehicle and further reducing the amount of water that comes into contact with the door hinge.
[0022] Furthermore, according to the present invention, the third drip passage is formed between an extension plate extending rearward from the rear end of the mounting portion of the first drip passage and a sub-seal lip extending upward from the extension plate and elastically contacting the door together with the main seal lip when the door is closed, thereby enabling water to be guided forward and further reducing the amount of water that gets on the door hinge.
[0023] In addition, according to the present invention, the inclination angle of the third drip passage relative to the horizontal plane on which the vehicle is placed is larger than the inclination angle of the first drip passage relative to the horizontal plane on which the vehicle is placed. Therefore, compared to when the inclination angle of the first drip passage is equal to or smaller than that of the first drip passage, water leaking from the first drip passage can be collected over a wider area, and the amount of water that gets on the door hinge can be further reduced.
[0024] In addition, according to the present invention, the sub-seal lip of the third drip passage is connected to the extended sub-lip of the second drip passage, and the extension plate of the third drip passage is connected to the extended base plate of the second drip passage, so that the amount of water dripping onto the door hinge can be reduced while maintaining the continuity of water conduction with a simple structure.

[0026] A drip weatherstrip according to an embodiment of the present invention will be described with reference to Figures 1 to 9. Note that the same parts as those shown in the conventional example are given the same reference numerals.
[0027] As shown in Figure 1, the drip weatherstrip 1 according to an embodiment of the present invention is attached to the door opening edge DK1 of the body B of an automobile 100 having a hinged door (front door) 101 that opens and closes via hinges H1 provided at the top and bottom. As shown in Figures 4 and 7, the drip weatherstrip 1 includes mounting portions 11, 21 that are directly attached to the door opening edge DK1, main seal lips 12, 22 that extend upward from the outer end of the mounting portions 11, 21 and elastically contact the door 101 when the door 101 is closed, and a first drip passage DT1 that can conduct water and is formed between the mounting portions 11, 21 and the main seal lips 12, 22. In addition, a rear seal lip 13, 23 is extended from the upper front side of the mounting portion 11, 21 and elastically contacts a molding extension plate FMb extending from the molding mounting portion FMa of the front fixed glass molding FM attached to the periphery of the front fixed glass FG toward the door opening edge DK1. As shown in FIG. 1, a second drip passage DT2 is provided below the first drip passage DT1, and a third drip passage DT3 is provided at the rear end of the second drip passage DT2.
[0028] The front fixed glass FG is fixed to the vehicle body B with a urethane adhesive or the like (not shown). As shown in Figures 4 and 7, the front fixed glass molding FM has molding attachment parts FMa attached to the ends of the front fixed glass FG on the (left and right) vehicle sides, and is equipped with molding extension plates FMb (not shown) that protrude from the interior vehicle side of the rear end of the molding attachment parts FMa toward the body opening edge DK1 and extend in the fore-and-aft direction of the vehicle.
[0029] As shown in FIG. 1, the drip weatherstrip 1 is formed by molding the lower end of an extruded portion that extends downward along the front pillar (A-pillar) from a position P that faces directly above the rear of the door 101 when the door 101 is closed, and as shown in FIG. 2, a molded mounting portion 21 and main seal lip 22 are connected to the extruded mounting portion 11 and main lip 12. In FIG. 2, a boundary line L1 is shown, and the front side (lower side) of the boundary line L1 indicates the molded part side, and the rear side (upper side) of the boundary line L1 indicates the extrusion molded part side.
[0030] As shown in FIG. 3, in the extrusion-molded portion of the drip weatherstrip 1, the mounting portion 11 is provided along the door opening edge DK1 and is composed of a base plate 11a that is inclined downward in cross section, an upper plate 11b that is connected to the upper end of the base plate 11a and extends diagonally upward, a lower plate 11c that is connected to the lower end of the base plate 11a and extends diagonally upward, and a lid 11d that connects the lower side of the upper plate 11b to the upper side of the lower plate 11c, and a hollow portion 11e is formed in the center. The main seal lip 12 is connected to the upper end of the lower plate 11c of the mounting portion 11, and is in elastic contact with the leading edge hem portion DOH of the outer panel DO of the front door 101 when the front door 101 is closed. The rear seal lip 13 is connected to the upper side of the upper plate 11b of the mounting portion 11, and is in elastic contact with the molding extension plate FMb of the front fixed glass molding FM. The first drip passage DT1 is formed between the lid 11d of the attachment portion 11 and the main seal lip 12 in the extrusion molding portion.
[0031] 4, the extrusion of the drip weatherstrip 1 is attached by fitting a clip C1, which is attached and fixed to a first hole BH1 provided in the base plate 11a of the attachment portion 11, into a hole provided in the door opening edge DK1. More specifically, the hole provided in the door opening edge DK1 is provided on a flat surface of the door opening edge DK1 of the vehicle body B that faces the interior surface of the leading edge hem portion DOH of the outer panel DO of the front door 101, and the drip weatherstrip 1 is attached to this facing flat surface of the door opening edge DK1.
[0032] First, as shown in Figures 2 and 5, the upper portion of the first drip passage DT1 in the molded portion of the drip weatherstrip 1 is the portion that is attached by the clip C2. Although it is a molded portion, its cross-sectional shape is made to be substantially the same as the extruded cross-sectional shape shown in Figure 4. Then, as shown in Figure 5, by fitting the clip C2, which is attached and fixed to the second hole BH2 formed in the first base plate 21a1 of the attachment portion 21, into a hole formed in the door opening edge DK1, the upper portion of the first drip passage DT1 in the molded portion is attached to the opposing flat surface of the door opening edge DK1. 2 and 6, the central portion of the first drip passage DT1 in the molded portion of the drip weatherstrip 1 is not attached by clips. The attachment portion 21 is made up of an upper mold portion plate 21b, a lower mold portion plate 21c, and a mold portion lid 21d, which are molded to extend continuously from the upper plate 11b, lower plate 11c, and lid 11d of the attachment portion 11 of the extrusion molded portion. 2 and 7, the lower portion of the first drip passage DT1 in the molded portion of the drip weatherstrip 1 is attached by clip C3. A mold section second base plate 21a2 is provided, which is connected to the mold section upper plate 21b and the mold section lower plate 21c and molded to extend away from the mold section lid 21d, thereby forming a mold section second hollow portion 21e2. The clip C3 is attached and fixed to a third hole BH3 formed in the second base plate 21a2 of the attachment portion 21, and is fitted into a hole formed in the door opening edge DK1, whereby the lower portion of the first drip passage DT1 in the molded portion is attached to the opposing flat surfaces of the door opening edge DK1. Finally, as shown in FIG. 2 and FIG. 9 described later, the lowest end portion of the first drip passage DT1 in the molded portion of the drip weatherstrip 1 is a portion that is not attached by a clip. As shown in Figures 2, 6, and 7, the main seal lip 22 is molded so as to extend continuously from the main seal lip 12 of the extrusion molded portion, is connected to the upper end of the lower plate 21c of the mounting portion 21, and elastically contacts the tip hem portion DOH of the outer panel DO of the front door 101 when the front door 101 is closed. The rear seal lip 23 is molded so as to extend continuously from the rear seal lip 13 of the extrusion molded portion, is connected to the upper side of the upper plate 21b of the mounting portion 21, and is in elastic contact with the molding extension plate FMb of the front fixed glass molding FM. The first drip passage DT1 is also formed in the molded portion between the lid 21d of the mounting portion 21 and the main seal lip 22, and extends continuously from the first drip passage DT1 formed between the lid 11d of the mounting portion 11 and the main seal lip 12 in the extrusion molded portion.
[0033] 7, an extension plate 24 is provided that extends rearward from the rear end of the lower plate 21c of the mounting portion 21, and a sub-seal lip 25 is provided that extends obliquely upward from the upper surface of the rear end of the extension plate 24. When the front door 101 is closed, the sub-seal lip 25 elastically contacts the front door 101 together with the main seal lip 22. More specifically, the sub-seal lip 25 elastically contacts a protruding step portion DID of the inner panel DI that is located below the leading edge hem portion DOH of the front door 101. A third drip passage DT3 is formed between the sub-seal lip 25 and the extension plate 24.
[0034] 1 and 2, the first drip passage DT1 extends from a position P that faces directly above the rear of the door 101 when the door 101 is closed to a position Q that is just directly above the door hinge H1. Alternatively, the first drip passage DT1 may be extended to a position just short of the position Q that is just above the door hinge H1. The main seal lip 22 of the molded portion that forms the first drip passage DT1 is gradually shortened in length from just before the position Q directly above the door hinges H1, H1, and completely disappears at the position Q directly above the door hinge H1. This prevents the front door 101 from interfering with the main seal lip 22 when the front door 101 is opened, as shown in FIG. 1 and 2, in this embodiment, the first drip passage DT1 is extended to just before the position Q directly above the door hinge H1, and is not located at the position Q directly above the door hinge H1, so the main seal lip 22 is not located there either. As described above, if the first drip passage DT1 were extended to the position Q just above the door hinge H1, the main seal lip 22 would The length is gradually shortened from just before the position Q directly above the door hinge H1, and the length is completely eliminated at the position Q directly above the door hinge H1.
[0035] As shown in Figures 1, 2 and 8, the second drip passage DT2 is formed between an extension base 31a located at a lower position than the mounting portion 21 that constitutes the first drip passage DT1, and an extension sub-lip 32 that extends upward from the lower portion of the extension base 31a, and extends from a position below the front end DT1E of the first drip passage DT1 to a position forward of the position Q directly above the door hinge H1. The rear end of the second drip passage DT2 is connected to the lower end of the lid 21d of the mounting part 21 that constitutes the first drip passage DT1, and then bends and extends forward from there to reliably receive the water W1 that falls from the front end DT1E of the first drip passage DT1. The water W1 received in the second drip passage DT2 descends the second drip passage DT2 and falls from the front position as water W2. The cross-sectional shape of the front position of the second drip passage DT2 is as shown in FIG.
[0036] As shown in Figures 1, 2, 7 and 9, the third drip passage DT3 extends from the rear end position of the second drip passage DT2 to a position rearward of the position Q directly above the door hinge H1, and receives water W3 that leaks to the rear or splashes out of the water W1 that falls from the first drip passage DT1 and cannot be received by the second drip passage DT2, and directs the water W3 into the second drip passage DT2.
[0037] As shown in FIG. 2, the sub-seal lip 25 of the third drip passage DT3 and the extension sub-lip 32 of the second drip passage DT2 are connected in a continuous, integrated manner, and the extension plate 24 of the third drip passage DT3 and the extension base plate 31a of the second drip passage DT2 are also connected in a continuous, integrated manner.
[0038] Also, as shown in FIG. 1, the inclination angle θ2 of the second drip passage DT2 with respect to the horizontal installation plane SM of the automobile 100 is smaller than the inclination angle θ1 of the portion of the first drip passage DT1 extending to the front end DT1E with respect to the horizontal installation plane SM of the automobile 100. This prevents water from splashing onto the hinge H1 in the second drip path DT2. In other words, if the inclination angle θ1 of the first drip path DT1 is maintained, the distance required to guide water forward of the hinge H1 becomes long. On the other hand, by setting the inclination angle θ2 of the second drip path DT2 to be smaller than the inclination angle θ1, the distance required to guide water forward of the hinge H1 becomes shorter.
[0039] Furthermore, the inclination angle θ3 of the third drip passage DT3 with respect to the horizontal installation plane SM of the automobile 100 is set to be larger than the inclination angle θ1 of the portion of the first drip passage DT1 that extends to the front end DT1E with respect to the horizontal installation plane SM of the automobile 100. This allows a wider area to receive water leaking from first drip passage DT1, compared to when the inclination angle θ3 of third drip passage DT3 is equal to or smaller than the inclination angle θ1 of first drip passage DT1.
[0040] The drip weatherstrip 1 configured in this manner comprises a first drip passage DT1, a second drip passage DT2, and a third drip passage DT3. The first drip passage DT1 extends from a position P opposite to the position directly above the rear of the front door 101 to just before the position Q directly above the door hinge H1. The second drip passage DT2 extends from a position below the front end DT1E of the first drip passage DT to a position forward of the position Q directly above the door hinge H1. Therefore, water W1 dropping from the front end of the first drip passage DT1 is received by the second drip passage DT2 and is channeled via the second drip passage DT2 to drop W2 at a position forward of the position Q directly above the door hinge H1. This reduces the amount of water that falls on the door hinge H1, making the door hinge H1 less susceptible to rust.
[0041] Furthermore, the third drip passage DT3 is arranged to extend from the rear end position DT2E of the second drip passage DT2 to a position rearward of the position Q directly above the door hinge H1, so that water W3 that falls from the first drip passage DT1 and cannot be received by the second drip passage DT2 can be received and flowed into the second drip passage DT2, further reducing the amount of water that falls on the door hinge H1.
[0042] Furthermore, the materials that can be used for the drip weatherstrip 1 are not particularly limited as long as they are rubber-like elastic bodies for both the extruded and molded parts, but in the case of rubber, EPDM sponge rubber is preferred, and in the case of thermoplastic resin, foamed TPO or soft TPO is preferred.
[0043] In this embodiment, the drip weatherstrip 1 is fixed to the body B of the automobile 100 using clips C1, C2, and C3, but it can also be fixed using double-sided tape instead.
