However, as shown in FIG. 13, when the inner side wall 22 is longer than the outer side wall 23 and the base of the inner lip 25 is located at a distance from the end 22 a of the inner side wall 22. When the door glass 9 is closed, a large space M1 is generated between the door glass 9 and the end 22a of the inner side wall 22 and the base of the inner lip 25. Become.
This is because the sound transmitted through the door glass 9 (the transmitted sound is indicated by a solid line in FIG. 13) echoes between the inner side wall 22 and the door glass 9 when it enters the space M1 (FIG. 13 shows an echo) Sound pressure levels are amplified, as indicated by the dotted lines. This is because the sound pressure level is larger when the echo is emitted inside the vehicle (in FIG. 13, the emitted sound is indicated by an alternate long and short dashed line) than before entering the space M1.

  Further, in FIG. 13, although the glass run 20 provided on the rear side longitudinal side 12 formed by extrusion molding has been described, the invention is not limited thereto, and as shown in FIG. Also in the glass run 20, when the door glass 9 is closed, a large space M2 is created between the door glass 9 and the end 22a of the inner side wall 22 and the base of the inner lip 25 so that the same quietness is achieved. There is a problem with

  Further, although the glass run 20 provided on the rear side longitudinal side 12 formed by extrusion in FIG. 13 has been described, this shape may be applied to the lateral side 13 formed by extrusion, Also have problems with silence.

On the other hand, the invention described in Patent Document 1 places the lip of the strip near the border and blinds the border in order to prevent the border between the strip and the flap connected thereto to stand out. There is no mention that the phenomenon that the sound transmitted through the door glass is reflected and amplified in the space formed by the glass and the flap is to be taken against the phenomenon.
Further, in the invention described in Patent Document 2, in order to improve the appearance by narrowing the sash width of the panel door, the elastic contact piece is provided which elastically contacts the panel from the center of the inner side wall portion longer than the outer side wall portion. In the same manner as in Patent Document 1, it is described that the sound transmitted through the door glass is reflected and amplified in the space formed by the glass and the flap, as in the case of Patent Document 1, and the countermeasure is taken against the phenomenon. Absent.

  Therefore, an object of the present invention is to provide a glass run that reduces the sound transmitted through the door glass from the outside of the vehicle.

In order to achieve the above object, the glass run of the present invention is fitted along a frame (400) provided on a door (200) of a vehicle, and moves up and down a door glass (9) in a groove (27) A cross section having a cross section substantially consisting of an outer side wall (23) and an inner side wall (22) longer in cross section than the outer side wall (23) and a connecting wall (24) connecting them. An outer lip portion (26) extending from the end portion (23a) of the outer side wall portion (23) to the vehicle inner side and in sliding contact with the door glass (9); The inner side of the side wall (22) extends from the outer side of the vehicle at a predetermined distance (L1, L2) to the connection wall (24) side from the end of the side wall (22) toward the vehicle outer side and contacts the door glass (9) A lip (25) and an end (22a) of the inner side wall (22) From the inner side of the inboard frame (402) of the frame (400) to the inboard side wall (22) of the inboard side of the inboard side frame (402) of the frame (400) A glass run (20) having resiliently holding retaining lip portions (28),
The in-vehicle side surface of the door glass (9) between at least the end (22a) or the end (22a) of the in-vehicle side wall (22) and the root (25b) of the inner lip (25) And sound insulation walls (100) for closing the concave spaces (M1, M2) that are generated therebetween are integrally or separately protruded.
Here, "close" means not only completely closing the outlet of the concave space (M1, M2) but also closing the outlet as little as possible.

  Further, the present invention is characterized in that the sound insulation wall (100) is provided such that a gap (S) with the door glass (9) is in a range of 0 mm or more and 1 mm or less.

  The symbols in parentheses indicate corresponding elements or items described in the drawings and the modes for carrying out the invention described later.

According to the present invention, in the glass run in which the cross-sectional shape of the main body portion is longer on the inner side wall portion side than the outer side wall portion and the inner lip portion is provided at a distance from the end of the inner side wall portion A sound insulation wall is formed between the base of at least the end of the side wall or near the end and the base of the inner lip to close the concave space created between the inner side of the door glass and the door lip. Sometimes, the sound transmitted through the door glass from the outside of the vehicle is reflected and amplified in the concave space, and the sound emitted to the inside of the vehicle can be shielded.
Thus, the discomfort to the crew is reduced.

A sufficient sound insulation effect can be obtained by providing such a sound insulation wall only partially, such as provided only at or near the end of the inner side wall.
On the other hand, although the material cost is high, the sound insulation wall is provided from the end or near the end of the inner side wall of the car to the base of the inner lip continuously to fill the concave space. It can also be reduced overall. According to this, the sound insulation wall can be reflected and amplified in the concave space, and not only can shield the sound emitted to the inside of the vehicle, but also reduce the space itself where the sound transmitted through the door glass can enter .
At this time, it is desirable that the sound insulation wall is not in contact with the inner lip portion so as not to adversely affect the sealability of the inner lip portion, but the present invention is not limited thereto.
For example, the inner lip portion may be set to be connected to the connection wall side end of the sound insulation wall. At this time, the inner lip is sealed against the door glass when the door glass is closed, and slides against the door glass when the door glass moves up and down, from the connecting wall side end of the sound insulation wall to the outside of the vehicle It is set to extend.

In addition, it is desirable that the sound insulation wall be provided so that the gap with the door glass is in the range of 0 mm or more and 1 mm or less, and furthermore, it is ideal to be in a 0 touch state of 0 mm. On the other hand, when it is smaller than 0 mm, that is, when the sound insulation wall is in elastic contact with the door glass, the vibration state of the door glass changes depending on the elastic contact portion, which affects the sound pressure level of the transmitted sound. . In a certain frequency band, the sound pressure level of the transmitted sound is undesirably increased.
In addition, although the lip | rip is set to the edge part of the vehicle interior side wall part in the above-mentioned patent document 1 and patent document 2, all are elastically in contact with door glass, and it is in this undesirable state.
Even when the inner lip is set to be connected to the connection wall side end of the sound insulation wall, the gap between the sound insulation wall and the door glass is provided so as to fall within the above range. Although it is desirable from the viewpoint of reducing the size, if the gap between the root of the inner lip and the door glass, which is set to extend from the connection wall side end of the sound insulation wall toward the vehicle exterior, is in the 0 touch state, the inner lip Is over-compressed to the door glass, in order to prevent this, the gap between the sound insulation wall and the door glass should be at least 1 mm at least at the part of the sound insulation wall connected to the root of the inner lip. Is desirable.

FIG. 1 shows a state in which the glass run 20 according to the embodiment of the present invention is assembled to a door sash (frame) 400, and corresponds to an enlarged cross section taken along line A-A of FIG. It corresponds to the 12 B-B line enlarged sectional view. The same parts as those shown in the conventional example are given the same reference numerals.

The glass run 20 according to the embodiment of the present invention is mounted on a door sash (frame) 400 attached by spot welding to a door panel 200 a of a press door type front door 200 (same as in the case of the rear door 300). The door glass 9 is guided into the groove 27.
In the case shown in FIG. 12, the glass run 20 shown in FIG. 1 extends upward from the inside of the door panel 200a of the front door 200, and is arranged vertically continuous across the position of the belt line BL. It applies to the side 12 and is usually formed by extrusion molding. The glass run 20 shown in FIG. 2 is applied to the molded part 15 in which the vertical side 12 and the horizontal side 13 of the front door 200 are connected, and is usually formed by molding.

  As shown in FIG. 1, the door sash 400 has a cross section substantially in the shape of a letter whose inner side is longer than the outer side of the vehicle, and the outer frame portion 401 and the inner frame portion 402 and a connecting frame portion connecting them. It consists of 403. Here, in the cross-sectional shape, the length of the inner frame portion 402 is approximately twice the length of the outer frame portion 401, and the outer frame portion 401 and the inner frame portion 402 are substantially parallel. In the inside frame part 402, a projecting part 402a which protrudes toward the vehicle outside is formed.

  Corresponding to the shape of the door sash 400, the shape of the glass run 20 is also a cross-sectional substantially "T" shape longer in the inner side than the outer side of the vehicle, forming the main body 21 forming the groove portion 27 for guiding the door glass 9 Have. The main body portion 21 is formed by two side wall portions, ie, an inner side wall 22 and an outer side wall 23, and a connecting wall 24 connecting the inner side wall 22 and the outer side wall 23. Here, in the cross-sectional shape, the length of the inner side wall 22 is approximately twice the length of the outer side wall 23. Further, in a state where the glass run 20 is assembled to the door sash 400, the inner side wall 22 and the outer side wall 23 are substantially linear in cross section, and the outer side wall 23 is substantially parallel to the outer frame 401 However, with respect to the side wall 22 side, the end 22a side of the side frame portion 402 is inclined toward the inside of the vehicle.

On the vehicle exterior surface at a position separated by a predetermined distance L1 from the end 22a of the vehicle interior side wall 22 to the connection wall 24 side, the connection wall is more specifically connected from the interior side wall 22 to the vehicle exterior, more specifically An inner lip portion 25 is formed, which extends toward the portion 24 toward the tip 25a.
Further, a bifurcated outer lip 26 extending inward is formed on the inner surface at the end 23a of the outer side wall 23, that is, on the inner side at the end 23a of the outer side wall 23. . The inner lip portion 25 and the outer lip portion 26 are provided so as to sandwich the door glass 9 from the inner side and the outer side of the vehicle and slide on the surface of the door glass 9.

  The outer lip portion 26 extends from the position of the end 23a of the outer side wall portion 23 toward the inner side of the vehicle, more specifically, toward the connecting wall portion 24 and is an inner contact lip 26X opposite to the inner lip portion 25. And an outer fitting lip 26Y substantially perpendicular to the extending direction of the inner fitting lip 26X from the base of the inner fitting lip 26X and extending in the opposite direction to the connecting wall 24 side, and is bifurcated .

  Further, lip portions 29a and 29b are provided on the inboard side wall portion 22 so as to extend toward the inner side and the outer side of the vehicle, respectively. A lip 29a extending from the inner side wall 22 to the inner side of the car is locked by a protrusion 402a provided on the inner side 402 of the door sash 400 and a lip 29b extending from the inner side wall 22 to the outer side is a door By sliding contact with the glass 9, the inner lip portion 25 is supported by being in contact with the inner side of the inner lip portion 25 bent toward the inner side wall portion 22 side.

  A holding lip 28 is provided on the inner side surface of the end 22a of the inner side wall 22. When the glass run 20 is assembled to the door sash 400, the holding lip portion 28 extends toward the rear of the vehicle so as to sandwich the inner side frame portion 402 of the door sash 400 with the inner side wall portion 22. The outer side of the holding lip portion 28 resiliently contacts the inner side surface of the inner frame portion 402 so that the glass run 20 fitted in the door sash 400 is held in the door sash 400. In addition, uneven portions 29d, 29e, 29f, 29g, and 29h for non-slip are respectively provided on the inner side and outer side of the inner side wall portion 22, inner side and outer side of the outer side wall portion 23, and outer side of the lip 29b. It is formed.

Then, as shown in FIG. 3, a sound insulation wall 100 is provided protruding above the belt line BL at an end 22 a of the inboard side wall 22.
The sound insulation wall 100 has a slender shape (bulk) having a substantially rectangular cross section, and is projected from the end 22 a of the inner side wall 22 in a direction substantially perpendicular to the surface of the door glass 9 on the outer side of the vehicle. Further, the sound insulation wall 100 is set so that the gap S with the door glass 9 is small, and the concave space M1 (between the end 22a of the inner side wall 22 and the root 25b of the inner lip 25 and the door The gap at the outlet of the space) between the glass 9 and the inner side of the car is closed. In the present embodiment, the gap S with the door glass 9 is provided so as not to elastically contact the door glass 9 within the range of 0 mm or more and 1 mm or less.

  Examples of the material of the main body portion 21 of the glass run 20, the inner lip portion 25, the outer lip portion 26, the holding lip portion 28 and the lip portions 29a and 29b include EPDM rubber, an olefin thermoplastic elastomer, and a styrene thermoplastic elastomer. There is no particular limitation. Moreover, as a product, the single structure by one of these materials may be sufficient, and the structure which combined 2 or more types may be sufficient. In addition, it may be foamed.

  Further, the sound insulation wall 100 can be formed of various known materials such as elastic rubber-like material and porous material, but in the present embodiment, by using solid rubber, it is integral with the main body 21 of the glass run 20 It has been molded.

  The sound insulation wall 100 is provided so as to protrude from the extruded glass run 20 as shown in FIG. 1, but as shown in FIG. 2, the sound insulation wall 100 is similarly integrally formed with the molded glass run 20 as well. It is provided in the In the glass run 20 shown in FIG. 2, the inner lip 25 is separated from the end 22 a of the inner side wall 22 by a predetermined distance L 2 from the end 22 a to the connecting wall 24 side. To the outside, more specifically, the tip 25 a side is formed to extend toward the connection wall 24 side. Further, the outer lip portion 26 extends from the end 23a of the outer side wall portion 23 toward the inner side of the vehicle, and unlike the extrusion molded portion (FIG. 1), is not bifurcated. The shapes of the inner lip 25 and the outer lip 26 are not particularly limited.

As described above, by projecting the sound insulation wall 100 at the end 22 a of the in-vehicle side wall 22, a concave space M1 (see FIG. 12) generated between the door glass 9 and the in-vehicle side wall 22 when the door glass 9 is closed. In the case of 2, the gap at the exit of the concave space M2) is reduced, so that the sound transmitted through the door glass 9 from the vehicle exterior when the door glass 9 is closed is reflected and amplified in the concave space M1, The sound emitted can be shielded.
Further, since the area of the concave space M1 itself is reduced by providing the sound insulation wall 100, the amount of the sound transmitted through the door glass 9 is reflected and amplified in the concave space M1 (in the case of FIG. 2, the concave space M2). Can also be reduced.

In the present embodiment, the long and narrow sound insulation wall 100 having a substantially rectangular cross section is protruded only at the end 22 a of the in-vehicle side wall 22, but this is the position of the end 22 a of the in-vehicle side wall 22. However, it may be around the end 22a.
Further, as shown in FIGS. 4 and 5, the sound insulation wall 100 is continued from the vicinity of the end 22a or the end 22a of the inner side wall 22 to the root 25b of the inner lip 25 to fill the concave spaces M1, M2. As a result, the concave spaces M1 and M2 may be reduced as a whole.
According to this, since the whole of the concave spaces M1 and M2 is filled with the sound insulation wall 100, the space itself to which the sound transmitted through the door glass 9 is reflected can be reduced.

Further, as shown in FIG. 15 and FIG. 16, the sound insulation wall 100 is provided continuously from the end 22a or the end 22a of the inner side wall 22 to the inner lip 25 to fill the concave spaces M1, M2. The concave spaces M1 and M2 may be further reduced. At this time, the inner lip portion 25 seals against the door glass 9 when the door glass 9 is closed, and slides on the door glass 9 when the door glass 9 moves up and down. It is set so as to extend from the portion 100a to the outside of the vehicle.
According to this, since the whole of the concave spaces M1 and M2 is filled with the sound insulation wall 100, the space itself in which the sound transmitted through the door glass 9 is reflected can be further reduced.

Further, the sound insulation wall 100 is provided so that the gap S with the door glass 9 does not elastically contact the door glass 9 within the range of 0 mm or more and 1 mm or less. However, as shown in FIGS. Even if the gap S with 9 is a little wider, for example, 6 mm, the outlets of the concave spaces M1 and M2 can be closed accordingly, so that the transmission of sound to the inside of the vehicle can be suppressed.
As shown in FIGS. 8 and 9, it is conceivable to make the sound insulation wall 100 into a seal lip shape having a substantially tongue-like cross section, but when the sound insulation wall 100 abuts on the door glass 9, the door glass Vibration conditions change, which affects the sound pressure level of the transmitted sound. In a certain frequency band, the sound pressure level of the transmitted sound is undesirably increased.
Ideally, a state of 0 touch where the gap S between the sound insulation wall 100 and the door glass 9 is 0 mm is ideal.

  Even when the inner lip 25 is set to be connected to the connection wall side end 100a of the sound insulation wall 100, the gap S between the sound insulation wall 100 and the door glass 9 should be within the above range. Although it is desirable from the viewpoint of reducing the sound pressure level of the transmitted sound, the gap S between the root of the inner lip 25 and the door glass 9 set to extend from the connecting wall side end 100a of the sound insulating wall 100 toward the vehicle exterior. In the state of 0 touch, the inner lip portion 25 becomes over-compressed with respect to the door glass 9, so in order to prevent this, at least the portion 100a of the sound insulating wall 100 to which the root of the inner lip portion 25 is connected It is desirable that the gap S between 100 and the door glass 9 be 1 mm or more.

Next, FIG. 10 shows the result of measurement of the volume transmitted to the inside of the vehicle when a sound is produced from a speaker (not shown) provided outside the vehicle at a position equivalent to the ear position on the glass side of the driver.
In FIG. 10 (a), when the gap S between the sound insulation wall 100 and the door glass 9 is 1 mm, in FIG. 10 (b), 0 touch is made with the gap S between the sound insulation wall 100 and the door glass 9 as 0 mm. In the case of FIG. 10C, the gap S between the sound insulation wall 100 and the door glass 9 is (−) minus 4 mm, that is, when the sound insulation wall 100 is elastically contacted to the gear glass 9 as shown in FIGS. , The relationship between the frequency and the sound pressure level.
According to this, it has been confirmed that the 0 touch state in a wide range such as 500 to 8000 Hz around the 3150 Hz that is the coincidence frequency of the door glass 9 is effective. Also, it was confirmed that the effect was good around 3150 Hz even when the gap S was 1 mm. In addition, it has been confirmed that when the gap S between the sound insulation wall 100 and the door glass 9 is (−) minus 4 mm, the sound pressure level rises around 2000 Hz to deteriorate the performance.

As a result of repeating such measurement, the sound insulation wall 100 provided at the exit of the concave spaces M1 and M2 is more effective in suppressing echo emission as the distance S with the door glass 9 becomes narrower, and the door glass It turned out that the effect becomes the maximum in the state which becomes 0 touch to 9.
When the sound pressure level is measured even when the distance S to the door glass 9 is 4 to 6 mm, the sound insulation wall 100 is not provided, the sound insulation wall 100 is provided, the space S is 4 to 6 mm, and the sound insulation wall 100 is provided. It was found that the sound pressure level decreased and the quietness was improved in the vehicle as the sound insulation wall 100 was provided and the interval S was set to 0 mm in the state of 1 mm.

Further, in the present embodiment, the sound insulation wall 100 is provided above the belt line BL at the rear side vertical side 12 up to the molded portion at the corner of the front door 200, but the ears of the crew at the rear side vertical side 12 It may be provided only around the height position of.
Alternatively, the sound insulation wall 100 may be provided up to the horizontal side portion 13 including the molded portion of the corner portion of the front door 200 above the belt line BL in the rear side vertical side portion 12.
Further, although the sound insulation wall 100 is integrally formed with the glass run 20, the separate sound insulation wall 100 may be attached to the glass run 20 using an adhesive, double-sided tape or the like.
