Description

  The present invention relates to a division bar for an automobile that is mounted in a substantially vertical direction between a door glass that moves up and down and a fixed panel.

As in the car shown in FIG. 5, there is a vehicle in which a division bar 100 for an automobile is attached in a substantially vertical direction between a door glass 1 that moves up and down on the rear door side and a fixed panel (for example, glass fixture glass) 2.
As such an automobile division bar 100, a steel bar has been conventionally used. However, in recent years, as shown in FIG. 6, in order to reduce the weight, the whole is made of a highly rigid rubber or resin. In addition, a glass run (glass run) that is integrally extruded is used (see Patent Document 1 and Patent Document 2).

The automobile division bar 100 shown in FIGS. 6A and 6B is obtained by integrally forming a holding portion 20 that supports the glass run 10 and the fixed panel 2. The glass run 10 includes a body portion 11 having a substantially U-shaped cross section composed of a vehicle interior side wall 11a, a vehicle exterior side wall 11b, and a bottom wall 11c, and a vehicle interior lip 12 provided at both ends of the body portion 11 and in sliding contact with the door glass 1. And a vehicle outer lip 13. Further, as shown in FIG. 6 (b), the vehicle interior side wall 11 a of the main body 11 has a vehicle when the vehicle interior lip 12 slidably contacting the vehicle interior side surface of the door glass 1 is bent when the door glass 1 is moved up and down. An intermediate lip 14 is provided that contacts and supports the tip of the inner lip 12. The sliding contact surfaces of the vehicle inner lip 12 and the vehicle outer lip 13 (the vehicle outer surface of the vehicle inner lip 12 and the vehicle inner surface of the vehicle outer lip 13) are covered with sliding materials 15 and 16. A metal core material 17 having a substantially U-shaped cross section is embedded in the main body 11 to keep the rigidity high.
The holding portion 20 includes two members that support the fixed panel 2 so as to sandwich the seal member 3 provided around the fixed panel 2 from the vehicle inner side and the vehicle outer side.

  According to such an automobile division bar 100, the weight can be reduced and the U-shaped metal core 16 can be embedded to maintain high rigidity, so that the sectional dimension accuracy is increased and the sectional shape is made compact. be able to. And the accuracy of the assembly position with respect to the vehicle body is high.

Japanese Patent No. 4890192 Japanese Utility Model Publication No. 61-30896

  However, according to the above-described automobile division bar 100, high rigidity is maintained, so that it is difficult to incorporate the door glass 1 into the glass run 10 of the automobile division bar 100 after the automobile division bar 100 is assembled to the vehicle body. There is a problem that it takes time and effort. That is, when the door glass 1 is assembled in the automobile division bar 100, the door glass 1 may be inserted in an inclined state, so that the end portion 1a of the door glass 1 and the bottom wall 11c of the main body portion 11 in the glass run 10 are included. If there is no clearance between them and there is no escape space for the door glass 1, it must be pushed in forcefully. Therefore, there is a problem that workability is poor and time is required.

  In addition, when the vehicle travels on a rough road, the door glass 1 fluctuates in the front-rear direction in the vehicle due to vibration, so that the end portion 1a of the door glass 1 is the main body of the glass run 10 as shown in FIG. When contacting the bottom wall of the part 11, there is a problem that an unpleasant tapping sound that resonates highly is generated.

  On the other hand, in the invention described in Patent Document 2, since a soft synthetic resin is provided on the bottom wall of the glass run and a coating film is formed by a sliding member on the surface thereof, it is possible to suppress the generation of a tapping sound. However, since a core material made of aluminum foil is only embedded on the outside of the vehicle, the overall rigidity is not maintained and the dimensional accuracy of the cross section is not high. Also, the assembly position accuracy with respect to the vehicle body is not high. In particular, since there is no metal core on the bottom wall, the accuracy of the partitioning position of the glass placed in front and back is inferior, and the clearance between the glasses cannot be reduced. Therefore, the division bar becomes large and the clearance with the glass is large.

  Accordingly, an object of the present invention is to provide an automotive division bar that is compact and excellent in assembling performance of the vehicle and that suppresses the generation of a beating sound due to rattling of the door glass after the assembling.

In order to achieve the above object, a division bar for an automobile according to the present invention is mounted in a substantially vertical direction between a vertically moving door glass (1) and a fixed panel (2), and has a substantially U-shaped cross section. A glass run (10) having a vehicle inner lip (12) and a vehicle outer lip (13) provided at both end portions of the portion (11) and the main body (11) and in sliding contact with the door glass (1), and the fixed panel (2) A rubber or resin automobile division bar (100) in which a holding portion (20) for supporting (2) is integrally extruded;
A metal core (17) having a substantially U-shaped cross-section embedded along the body (11) of the glass run (10);
Provided on the inner surface side of the bottom wall (11c) of the main body (11) of the glass run (10) opposite to the end (1a) of the door glass (1) so as to extend perpendicular to the door glass (1). It is provided with the soft material (30) which can be used.

In addition, the present invention is mounted in a substantially vertical direction between the elevating door glass (1) and the fixed panel (2), and has a body portion (11) having a substantially U-shaped cross section and both ends of the body portion (11). A glass run (10) having a vehicle inner lip (12) and a vehicle outer lip (13) slidably in contact with the door glass (1) and a holding unit (20) for supporting the fixed panel (2) are integrated. A rubber or resin automotive division bar (100) formed by extrusion,
A metal core (17) having a substantially U-shaped cross-section embedded along the body (11) of the glass run (10);
Provided on the inner surface side of the bottom wall (11c) of the main body (11) of the glass run (10) opposite to the end (1a) of the door glass (1) so as to extend perpendicular to the door glass (1). Soft material (30),
A flat sliding layer is formed so as to cover the surface of the soft material (30), and a sliding contactable with the end (1a) of the door glass (1) when the door glass (1) moves up and down. A moving material (40) is provided.

  In the invention, it is preferable that the soft material (30) is provided so as to be in contact with the vehicle inner side wall (11a) and the vehicle outer side wall (11b) of the main body (11) of the glass run (10). And

  Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

  According to the present invention, a rubber or resin automotive division bar in which a glass run and a holding portion are integrally formed by extrusion, a metal core material having a substantially U-shaped cross section along the main body portion of the glass run. As a result, the division bar for automobiles can be made compact and high rigidity can be maintained. And the soft material is provided in the bottom wall inner surface side of the main-body part of a glass run. The soft material does not become an obstacle at the time of raising and lowering if the door glass is lifted and lowered at a normal reference position so as not to contact the end portion of the door glass. When the edge of the door glass enters the bottom wall of the glass run body from the reference position, the soft material elastically contacts the edge of the door glass. If the door glass is inserted in a state where it is inserted, there will be a door glass escape space between the edge of the door glass and the bottom wall of the main body, so there is a gap between the edge of the door glass and the bottom wall of the main body. Even if the clearance of the door is small, the door glass cannot be assembled, or the parts will not be damaged by force. Therefore, it can be assembled in a short time without particularly deteriorating workability.

  Also, when the end of the door glass enters the bottom wall side of the glass run body from the reference position due to vibration during running on a rough road, the soft material provided on the inner side of the bottom wall of the glass run main body Since the soft material is elastically bent and exerts a buffering function, the occurrence of an unpleasant tapping sound that resonates with high “concon” as shown in the conventional example is suppressed. This beating sound makes a louder sound as the ramp width of the door glass in the glass run increases. However, as described above, the automobile division bar is compact and the clearance between the end of the door glass and the bottom wall of the main body is reduced. Therefore, the generation of sound is also suppressed by reducing the rampage.

  Furthermore, the soft material is provided so as to extend perpendicularly to the inner surface of the bottom wall of the glass run main body in the direction in which the door glass enters. Therefore, when the door glass is incorporated into an automobile division bar, Thus, even if the end of the door glass fluctuates in the left-right direction of the vehicle, the amount of elastic contact is constant. Therefore, even if the end portion of the door glass fluctuates in the left-right direction of the vehicle, it can be incorporated evenly, and it does not become a great resistance when the door glass is raised and lowered.

Further, according to the present invention, since the flat sliding layer is formed so as to cover the surface of the soft material, and further provided with the sliding material that can contact the end portion of the door glass when the door glass moves up and down, the door Compared with the case where the end of the glass is in contact with the sliding material, the sliding resistance is reduced as compared with the case where the glass is not in contact with the sliding material, and the door glass moves up and down smoothly and the durability of the glass run is improved.
According to this, the position of the soft material on which the sliding layer is formed, for example, the shape of the soft material bends even when the end portion of the door glass that moves up and down normally contacts the sliding layer at the reference position. However, when the door glass is installed or when driving on rough roads, if the edge of the door glass enters the bottom wall side of the glass run body from the reference position, the shape of the soft material will be bent and a position where the buffer function is exhibited. Thus, it is possible to obtain a compact automotive division bar that can be easily incorporated into the glass run of the automotive division bar and that can suppress the generation of a tapping sound after being incorporated.

  Further, according to the present invention, since the soft material is provided so as to be in contact with the vehicle inner side wall and the vehicle outer side wall of the glass runn main body, the end portion of the door glass largely fluctuates in the left-right direction of the vehicle. Can also respond.

  As described above, the present invention holds the glass run main body with high rigidity by embedding a metal core having a substantially U-shaped cross section in a glass run of a rubber or resin automotive division bar. By increasing the accuracy, the soft material or the soft material with the sliding layer is accurately provided at a position determined corresponding to the position of the end portion of the door glass. Even if a metal core material having a substantially U-shaped cross section is embedded as in 1, the soft material is not provided at the position corresponding to the edge of the door glass. However, it is difficult to conceive of the present invention by combining the contents of Patent Document 2 that are not considered to have a high dimensional accuracy, but the idea of combining both Patent Documents 1 and 2 in the first place arises. Not to.

Shows the state after.

A vehicle division bar according to an embodiment of the present invention will be described with reference to FIGS. 1 and 5. The same parts as those shown in the conventional example are denoted by the same reference numerals.
An automotive division bar 100 according to an embodiment of the present invention is made of a resin (rubber) that is attached in a substantially vertical direction between a door glass 1 that moves up and down a rear part of a rear door of an automobile and a fixed panel (for example, glass fixture glass) 2. The glass run 10 and the holding part 20 are integrally extruded. And in the division bar 100 for motor vehicles based on embodiment of this invention, the metal core material 17, the soft material 30, and the sliding material 40 are provided especially.

The glass run 10 has a main body portion 11 having a substantially U-shaped cross section, and a vehicle inner lip 12 and a vehicle outer lip 13 that are provided at both ends of the main body portion 11 and are in sliding contact with the door glass 1. The main body 11 includes a vehicle inner side wall 11 a, a vehicle outer side wall 11 b, and a bottom wall 11 c, and a metal core material 17 having a substantially U-shaped cross section is embedded along the main body 11. As a result, the automobile division bar 100 can be made compact and high rigidity can be maintained.
Moreover, as shown in FIG.1 (b), after the door glass 1 is integrated in the vehicle interior side wall 11a of the main-body part 11, the vehicle interior lip 12 which slidably contacted with the vehicle inner side surface of the door glass 1 at the time of raising / lowering, for example. An intermediate lip 14 is provided to support the vehicle inner lip 12 by contacting the tip of the vehicle inner lip 12 when bent. The sliding contact surfaces of the vehicle inner lip 12 and the vehicle outer lip 13 (the vehicle outer surface of the vehicle inner lip 12 and the vehicle inner surface of the vehicle outer lip 13) are covered with sliding materials 15 and 16.
The holding portion 20 includes two members that support the fixed panel 2 so as to sandwich the seal member 3 provided around the fixed panel 2 from the vehicle inner side and the vehicle outer side.

The soft material 30 has a flat shape, and is provided on the inner surface side of the bottom wall 11c of the main body 11 of the glass run 10 so as to face the end 1a of the door glass 1 so as to extend perpendicularly to the door glass 1. . The soft material 30 may be provided so as to be adhered to the inner surface side of the bottom wall 11c of the main body 11 of the glass run 10, but here, the soft material 30 is extruded simultaneously and integrally with the glass run 10 and the holding unit 20. Is provided by.
A flat sliding layer is formed on the surface of the soft material 30 by the sliding material 40 so that the end portion 1a of the door glass 1 can be contacted when the door glass 1 moves up and down.
Moreover, the soft material 30 is extended so that it may each contact | connect the vehicle interior side wall 11a and the vehicle exterior side wall 11b of the main-body part 11 of the glass run 10 with a flat sliding layer.

Normally, the position of the soft material 30 with the sliding layer is set so that the shape of the soft material 30 does not bend even if the end 1a of the door glass 1 that moves up and down contacts the sliding layer 40 at the reference position. When the end portion 1a of the door glass 1 enters the bottom wall 11c side of the main body portion 11 of the glass run 10 when the glass 1 is assembled or when traveling on a rough road, the shape of the soft material 30 is bent to provide a buffering function.
With respect to this installation position, the door glass 1 is smoothly raised and lowered by the action of the sliding layer without causing a resistance (obstacle) of the door glass 1 in which the soft material 30 is raised and lowered normally. When the end portion 1a of the door glass 1 enters the side of the bottom wall 11c of the body portion 11 of the glass run 10 from the reference position when the road is not normal such as when traveling on a rough road, the soft material 30 is bent to exert a buffer function. I am letting. Since the metal core 17 having a substantially U-shaped cross section is embedded in the main body 11 of the glass run 10, the dimensional accuracy is set high, so even if the clearance between the door glass 1 and the fixed panel 2 is small. There is almost no variation in position, and it is attached to the vehicle body with high positional accuracy, and there is no problem even if the glass run 10 and the holding portion 20 are made compact.

  Here, with respect to the reference position of the end portion 1a of the door glass 1 that moves up and down, the end portion 1a of the door glass 1 is separated from the sliding layer 40 as shown by the solid line in FIG. Position. However, depending on the movement of the door glass 1, the end portion 1a of the door glass 1 may be in the position (P) indicated by a dotted line. The end portion 1a of the door glass 1 that moves up and down comes into contact with the sliding layer. The shape of 30 does not bend, so that it does not become a resistance (obstacle), and the door glass 1 is raised and lowered smoothly.

  The material of the soft material 30 is not particularly limited as long as the end portion 1a of the door glass 1 is elastically contacted and exhibits a cushioning function as a flexible cushion material, and the sliding material 40 is also slid. The material is not limited as long as it exhibits a normal sliding function like the moving materials 15 and 16.

  According to the automotive division bar 100 configured as described above, it is easy to incorporate the automotive division bar 100 into the glass run 10. That is, if the door glass 1 is assembled in an inclined state after the automobile division bar 100 is assembled to the vehicle body, the end portion 1a and the main body of the door glass 1 are bent by the flexible material 30 being bent. Since the escape window of the door glass 1 is generated between the bottom walls 11c of the part 11, even if the clearance between the end part 1a of the door glass 1 and the bottom wall 11c of the main body part 11 is small, the door glass 1 cannot be assembled. Do not force the parts to be damaged. Therefore, it can be assembled in a short time without particularly deteriorating workability.

Moreover, after the door glass 1 has been incorporated into the glass run 10 of the automobile division bar 100, the generation of the hitting sound can be suppressed. That is, the end portion 1a of the door glass 1 enters the bottom wall 11c side of the main body portion 11 of the glass run 10 by vibration during traveling on a rough road, and the end portion 1a of the door glass 1 in FIG. Even if the abrupt movement and the collision with the bottom wall 11c are repeated, the end 1a of the door glass 1 elastically contacts the soft material 30 provided on the inner surface side of the bottom wall 11c of the main body 11 of the glass run 10, and the soft material Since the shape of 30 is bent and exhibits a buffering function, the occurrence of an unpleasant tapping sound that resonates highly as shown in the conventional example is suppressed. The beating sound becomes louder as the ramp width of the door glass 1 in the glass run 10 is larger. However, since the automobile division bar 100 is made compact, noise can be generated even if the ramp width of the door glass 1 is reduced. It is suppressed.
At this time, in addition to the high sound range, the generated sound is suppressed by about 10 to 20 (dB) in the entire frequency range, and an improvement effect is recognized to a level that can be understood even when actually heard by ear.

  As shown in FIG. 2, only the soft material 30 (the sliding layer by the sliding material 40 is provided on the inner surface side of the bottom wall 11 c of the main body portion 11 of the glass run 10, which faces the end portion 1 a of the door glass 1. When the door glass 1 moves up and down at a normal reference position (the position indicated by the solid line in FIG. 2), the end 1a of the door glass 1 is The end 1a of the door glass 1 has a predetermined amount T from the reference position (the distance between the position of the end 1a of the door glass 1 that moves up and down normally and the surface of the soft material 30). If the swing width of the door glass 1 is defined to be a predetermined amount T so that the glass run 10 enters the bottom wall 11c side of the main body 11 of the glass run 10 and elastically contacts the end 1a of the door glass 1, the sliding layer 40 can be abolished. Even in this case, according to the present invention, the predetermined amount T can be set smaller than the conventional clearance. The regulation of the swing width of the door glass 1 can be achieved by, for example, a door glass driving mechanism.

  Therefore, in FIG. 2, the reference position of the door glass 1 is set to a position immediately before contacting the surface of the soft material 30, and the end portion 1a of the door glass 1 enters the bottom wall 11c side of the main body portion 11 of the glass run 10 even slightly. And can be made to elastically contact the soft material 30.

  3, the soft material 30 is embedded in the bottom wall 11c of the main body 11 of the glass run 10, and the inner surface side of the bottom wall 11c (the door glass 1 side from the embedded soft material 30) is hard material 50. It may be formed so that the sliding function is exhibited. At this time, the embedment position of the soft material 30 is normally set such that the shape of the soft material 30 does not bend even if the end 1a of the door glass 1 that moves up and down contacts the portion of the hard material 50. When the end 1a of the door glass 1 enters the side of the bottom wall 11c of the main body 11 of the glass run 10 during assembling or running on a rough road, it is preferable that the shape of the soft material 30 bend and be set to a position that exhibits a buffering function.

Further, in the present embodiment, the holding unit 20 supports the fixed panel 2 so as to sandwich the sealing member 3 provided around the fixed panel 2 from the vehicle inner side and the vehicle outer side. As described above, the fixing panel 2 may be directly sandwiched and supported without using the seal member 3.
Further, as shown in FIG. 4 (a), the intermediate lip 14 may not be provided, and as shown in FIG. 4 (b), the vehicle inner side and the vehicle outer side of the soft material 30 with the sliding layer. The corners on the inner surface side of the end portions may be curved to prevent the glass run 10 from being turned over or peeled off from the main body 11.

  In the embodiment of the present invention, the automobile division bar 100 provided at the rear part of the rear door of the automobile has been described. However, it is attached in a substantially vertical direction between the door glass that moves up and down and a fixed panel (for example, glass fixture glass). It can be applied even if it is attached to the front door side. Further, the fixed panel does not need to be made of a glass material, and the material such as resin or metal is not limited.
