Description

The present invention relates to a glass run that is fitted along a frame provided on a vehicle door to guide a door glass that moves up and down.

As shown in FIG. 7, the glass run 100 is fitted in the frame (door sash) of the front door 1 and the rear door 2 of the vehicle, or in the frame (door sash) 4 of the sliding door 3 as shown in FIG. It is dressed to guide the door glass 5 that goes up and down.
FIG. 9 shows a glass run 100 attached to the frame (door sash) 4 of the sliding door 3. The glass run 100 is composed of a front vertical side portion 100A and a rear vertical side portion 100B extending upward from the inside of the door panel of the sliding door 3, and a horizontal side portion 100C connecting the upper ends of the two vertical side portions 100A and 100B. ing. The front vertical side portion 100A is fitted along the so-called B pillar, and the rear vertical side portion 100B is fitted along the C pillar. The two vertical side portions 100A and 100B and the horizontal side portion 100C are usually formed by extrusion molding, and the vertical side portions 100A and 100B and the horizontal side portion 100C are connected to each other via a mold forming portion.

Such a glass run 100 is fitted along a frame body 4 having a substantially U-shaped cross section, and has a main body portion 10 having a substantially U-shaped cross section in which a groove portion 15 to which a door glass 5 for raising and lowering is assembled is formed inside. The main body portion 10 is formed by two side wall portions, that is, a connecting wall portion 13 connecting the car inner side wall portion 11, the car outer side wall portion 12, and the car inner side wall portion 11 and the vehicle outer side wall portion 12. .. An inner lip portion 17 extending toward the connecting wall portion 13 is formed on the inner surface of the vehicle inner side wall portion 11, that is, the vehicle outer surface of the vehicle inner side wall portion 11, and the inner surface of the vehicle outer side wall portion 12, that is, An outer lip portion 18 extending toward the connecting wall portion 13 side is formed on the vehicle inner side surface of the vehicle outer side wall portion 12. When the door glass 5 is raised and lowered, the inner lip portion 17 is in sliding contact with the inner surface side of the door glass 5, and the outer lip portion 18 is in sliding contact with the outer surface side of the door glass 5.

However, when assembling the door glass 5 to the glass run 100, the operator manually attaches the door glass 5 to the front vertical side portion 100A and the rear vertical side portion 100B after the glass run 100 is fitted to the frame 4 of the sliding door 3. After fitting the door glass 5 into one vertical side portion, for example, the front vertical side portion 100A, the door glass 5 is fitted into the other vertical side portion, for example, the rear vertical side portion 100B so as to be fitted in between. The work of inserting was very difficult and it took a long time to assemble.
This is because when the door glass 5 is fitted into the front vertical side portion 100A, the clearance at which the tip of the door glass 5 can be pushed from the groove portion 15 to the connecting wall portion 13 side with respect to the reference position M of the door glass 5 is provided. , As shown in FIG. 10, the connecting wall portion 13 is projected inward on the door glass 5 side, and one end of the vehicle outer side wall portion 12 is floated from the frame body 4 to absorb the impact when the tip of the door glass 5 collides. Even in the glass run 100 of the type considered to be used, the clearance is the distance L2 between the tip of the door glass 5 and the inner surface of the connecting wall portion 13, and the distance L3 between one end of the outer side wall portion 12 of the vehicle and the frame body 4. Since there is only a distance and the connecting wall portion 13 does not bend significantly, the fitting work of the door glass 5 is complicated. Further, as shown in FIG. 9, in order to increase the distance L1 between the tip of the door glass 5 and the inner surface of the connecting wall portion 13, a glass run 100 of a type that does not have a buffer structure for the tip of the door glass 5 may be used. However, as will be described later, if there is no buffer structure, abnormal noise due to vibration or collision of the door glass 5 is generated, and the distance between the tip of the door glass 5 and the inner surface of the connecting wall portion 13 is only L1, which is not preferable. ..

The difficulty of fitting the door glass 5 is less likely to be a problem because the door glass 5 on the front door 1 side shown in FIG. 7 has a shape in which the front side of the vehicle is inclined and descends, and FIG. 7 In the door glass 5 on the rear door 2 side shown in the above, the division bar 7 that separates the rear quarter glass 6 and the door glass 5 can be inserted after the door glass 5 is assembled, so this is also not a problem. Absent.
On the other hand, as shown in FIG. 8, the type in which the rectangular door glass 5 is fitted between the vertical side portions 100A and 100B erected from the front and back of the door panel of the sliding door 3 has particularly good assembly workability. It becomes a problem.

On the other hand, in FIG. 5 of Patent Document 1, by forming a stretchable portion having a substantially V-shaped cross section protruding toward the door glass on the connecting wall portion of the glass run, the stretchable portion of the door glass is formed when the door glass is closed. A device that absorbs an impact and reduces the generation of impact noise by bringing the end faces into contact with each other is disclosed.

Japanese Patent No. 4385859

However, the telescopic portion formed in the glass run described in Patent Document 1 is folded so that the inner variable portion and the outer variable portion overlap each other to form a lip shape, and is laterally caused by vibration of the door glass during traveling. Although the movement is regulated, the structure is related to the lateral side portion 100C (roof side of the vehicle) shown in FIG. 8, and does not eliminate the difficulty when incorporating the door glass into the glass run.
Further, the glass run described in Patent Document 1 is attached to the front door of the vehicle, and there is no particular problem with the difficulty of fitting the door glass.
Further, the glass run described in Patent Document 1 has a cross section in which the main body portion is in an undeveloped state by contracting the telescopic portion to move the car inner side wall portion and the car outer side wall portion in parallel when the glass run is attached to the frame body (sash). Since it is fitted while maintaining a substantially U-shape, when the glass run is attached to the frame, pressure is applied to the inner side wall of the car and the outer side wall of the car so that they spread outward. There is a problem that it becomes difficult to set the target pressure when sliding the inner lip portion and the outer lip portion.

Therefore, an object of the present invention is to provide a glass run structure capable of improving the assembling workability of the door glass with respect to the glass run having a buffer structure for the tip of the door glass.

The glass run 100 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 5 and 8. The same parts as those shown in the conventional example are designated by the same reference numerals.
As shown in FIG. 8, the glass run 100 according to the embodiment of the present invention is fitted into a frame (door sash) 4 having a substantially U-shaped cross section of the sliding door 3, and the door glass 5 moves up and down in a substantially rectangular shape. It is designed to guide you.
The glass run 100 has a front vertical side portion 100A and a rear vertical side portion 100B, and two vertical side portions 100A, which are erected substantially parallel to the front and rear of the vehicle so as to extend upward from the inside of the door panel of the sliding door 3. , It is composed of a horizontal side portion 100C connecting the upper ends of 100B. The front vertical side portion 100A is fitted along the B pillar, and the rear vertical side portion 100B is fitted along the C pillar. The two vertical side portions 100A and 100B and the horizontal side portion 100C are usually formed by extrusion molding, and the vertical side portions 100A and 100B and the horizontal side portion 100C are connected to each other via a mold forming portion. The front vertical side portion 100A and the rear vertical side portion 100B are attached to the frame body 4 so as to face each other on the opening side, and are substantially the same except for the attachment direction. The side portion 100A will be described as an example. That is, the procedure of fitting the tip of the door glass 5 into the front vertical side portion 100A first and then fitting it into the rear vertical side portion 100B will be described. On the contrary, the rear vertical side portion 100B is fitted into the front side in advance. There is no difference in using the vertical side portion 100A after that.

The glass run 100A (100) has a main body portion 10 having a substantially U-shaped cross section forming a groove portion 15 for guiding the door glass 5 to be raised and lowered, and the main body portion 10 is a car inner side wall portion 11 which is two side wall portions. It is formed by a connecting wall portion 30 that connects the vehicle outer side wall portion 12 and the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12.
An inner lip portion 17 extending from the vehicle inner side wall portion 11 toward the connecting wall portion 30 side is formed on the vehicle outer side surface of the vehicle inner side wall portion 11, and the vehicle inner side wall surface of the vehicle outer side wall portion 12 is formed. An outer lip portion 18 extending from the portion 12 toward the connecting wall portion 30 side is formed. The inner lip portion 17 and the outer lip portion 18 are provided so as to sandwich the door glass 5 from the inside of the vehicle and the outside of the vehicle, and are in sliding contact with the surface of the door glass 5 that moves up and down.

Further, a lip portion 19a extends toward the outside of the vehicle on the inner side wall portion 11 of the vehicle. The lip portion 19a abuts on the inside of the vehicle of the inner lip portion 17 that bends toward the side wall portion 11 on the inner side of the vehicle by sliding contact with the door glass 5 to support the inner lip portion 17. Further, a holding lip portion 19b is provided on the inner side surface of the vehicle at the end portion of the inner side wall portion 11 of the vehicle, and the end portion of the frame body 4 is inserted between the holding lip portion 19b and the inner side wall portion 11 of the vehicle. Then, the glass run 10 is held.

As shown in FIG. 1, the connecting wall portion 30 is composed of a first connecting wall portion 31 having a substantially V-shaped cross section and a second connecting wall portion 32 having a substantially mountain-shaped cross section.

One end 31a of the first connecting wall portion 31 is connected to one end of the vehicle outer side wall portion 12, and the other end 31b of the first connecting wall portion 31 is located closer to the other end side of the vehicle outer side wall portion 12. Have been placed. That is, the opening of the first connecting wall portion 31 faces the vehicle outer side wall portion 12 side, and the top portion 31c of the first connecting wall portion 31 faces the vehicle inner side wall portion 11 side. Further, the top portion 31c of the first connecting wall portion 31 is located on the opening side of the main body portion 10 with respect to the straight line T connecting one end of the vehicle outer side wall portion 12 and one end of the vehicle inner side wall portion 11.
This is because, as will be described later, the first connecting wall portion 31 having a substantially V-shaped cross section exerts a high bending and stretching motion. That is, the first connecting wall portion 31 bends when the tip of the door glass 5 collides with and is pushed in, and is restored to its original state when separated. Therefore, if the top portion 31c of the first connecting wall portion 31 is provided on a straight line T connecting one end of the vehicle outer side wall portion 12 and one end of the vehicle inner side wall portion 11, the top portion 31c of the first connecting wall portion 31 and the first portion 31c are provided. Since the wall portion connecting the other end 31b of the one connecting wall portion 31 approaches the side surface of the door glass 5 in parallel (the angle of intersection with the side surface of the door glass 5 is small), it is difficult to bend, which is not preferable. Further, while ensuring flexibility (increasing the angle of intersection with the side surface of the door glass 5), the top portion 31c is provided on a straight line T connecting one end of the vehicle outer side wall portion 12 and one end of the vehicle inner side wall portion 11. Then, the distance between the wall portion connecting the top portion 31c and the other end 31b becomes unnecessarily large. Further, since one end 31a of the first connecting wall portion 31 does not operate as a bending point, the flexibility is also inferior.

Further, the second connecting wall portion 32 connects the other end 31b of the first connecting wall portion 31 and one end of the car inside side wall portion 11, and the other end 31b of the first connecting wall portion 31 connects the other end 31b of the vehicle outer side wall portion 12. It extends in a direction substantially orthogonal to the vehicle, and is curved (may be bent) on the indoor side, here at substantially the center of the groove portion 15, and is inclined to extend to one end of the car inside side wall portion 11.

In the cross-sectional shape of the first connecting wall portion 31, the length from the top portion 31c to one end 31a connected to one end of the vehicle outer side wall portion 12 is slightly longer than the length from the top portion 31c to the other end 31b. And as shown in FIG. 2, the other end 31b of the first connecting wall portion 31 does not contact the vehicle outer side wall portion 12 until the door glass 5 abuts on the second connecting wall portion 32, but the door glass 5 When the first connecting wall portion 31 abuts on the second connecting wall portion 32 and bends so as to close the opening having a substantially V-shaped cross section in conjunction with the movement of the second connecting wall portion 32, the other end 31b is shown in FIG. As shown, it is in contact with the outer side wall portion 12 of the vehicle. As shown in FIG. 4, even when the door glass 5 is pushed in so that the substantially V-shaped opening of the first connecting wall portion 31 is bent so as to completely close, the first connecting wall portion 31 and others The length of the end 31b from the top 31c of the first connecting wall 31 to the other end 31b can be set so as not to come into contact with the outer side wall portion 12 of the vehicle.

Further, in the cross-sectional shape of the second connecting wall portion 32, the length from one end 32a connected to the other end 31b of the first connecting wall portion 31 to the curved portion 32c is larger than the length from the curved portion 32c to the car inside side wall portion 11. The length up to the other end 32b connected to one end of the is longer. Moreover, the curved portion 32c to the other end 32b of the second connecting wall portion 32 bulges and curves toward the opening side of the main body portion 10, and as shown in FIG. 4, the door glass 5 is pushed in. When the opening having a substantially V-shaped cross section of the first connecting wall portion 31 is bent so as to be completely closed, it is prevented from contacting the top portion 31c of the first connecting wall portion 31. As a result, the top portion 31c of the first connecting wall portion 31 does not press the end of the car inside side wall portion 11 on the connecting wall 30 side via the second connecting wall portion 32, and the glass run 100A is assembled. Does not affect the state of attachment.

Further, the thickness of the first connecting wall portion 31 and the thickness of the second connecting wall portion 32 are substantially the same, and are slightly thinner than the thickness of the vehicle outer side wall portion 12. Then, as shown in FIG. 4, when the door glass 5 is pushed in and the opening having a substantially V-shaped cross section of the first connecting wall portion 31 is bent so as to completely close, the car at the tip of the door glass 5 is bent. The curved portion 32c of the second connecting wall portion 32 abuts on the inside, and the tip of the door glass 5 is pushed toward the car outer side wall portion 12 by pressing the curved portion 32c. As a result, as shown in FIG. 5, the door glass 5 pushed so that the connecting wall portion 30 bottoms out can be easily tilted in the groove portion 15 with the tip of the door glass 5 as a fulcrum and the opposite side toward the inside of the vehicle. Can be done.

Examples of the material of the main body 10, inner lip 17, and outer lip 18 of the glass run 100A include EPDM rubber, olefin-based thermoplastic elastomer, and styrene-based thermoplastic elastomer, but the material is not particularly limited, and is rubber-like. It may be an elastic body. Further, the product may have a single configuration made of one of these materials, or may have a configuration in which two or more types are combined. It is also possible to use a foamed one.

According to the glass run 100A configured in this way, when the operator manually assembles the door glass 5 to the glass run 100A fitted to the frame body 4, the tip of the door glass 5 is inserted into the groove portion 15. The door glass 5 comes into contact with the second connecting wall portion 32, and the pressure pushed from the second connecting wall portion 32 into the first connecting wall portion 31 is transmitted. At the same time, the stress of pushing back the tip of the door glass 5 from the first connecting wall portion 31 to the second connecting wall portion 32 is exerted.
When the door glass 5 is further pushed in from this contact state, the first connecting wall portion 31 corresponds to this, from the top 31c to a portion from the top 31c to one end 31a in the cross-sectional shape, as shown in FIG. Since the portions up to the other end 31b overlap and bend so as to completely close the opening having a substantially V-shaped cross section, sufficient clearance can be provided when assembling the door glass 5 to the glass run 100A.

Therefore, after the front side of the door glass 5 is assembled to the groove portion 15 of the glass run 100A which is the front vertical side portion, the rear side of the door glass 5 is easily assembled to the groove portion 15 of the glass run 100B which is the rear side vertical side portion. Can be attached. That is, in the glass run 100B which is the rear vertical side portion, the tip of the door glass 5 needs to "dodge" the window opening side end portion of the vehicle outer side wall portion 12 on the glass run 100B, but the glass run on the front vertical side portion. Sufficient clearance at 100A allows for a "dodge" action on the posterior vertical side portion 100B.

Further, the second connecting wall portion 32 has a substantially mountain-shaped cross section, and when the door glass 5 abuts between one end 32a on the outside of the vehicle of the second connecting wall portion 32 and the curved portion 32c, the second connecting wall portion 32 is curved from the one end 32a. Since the portion of the side extending to the portion 32c inclined from the direction substantially orthogonal to the vehicle outer side wall portion 11 toward one end side of the vehicle outer side wall portion 11, the tip of the door glass 5 slides along the inclined direction. Since it is easily guided and pushed to the back side of the groove portion 15, the burden on the operator can be reduced and the assembling workability of the door glass 5 can be further improved.

Further, when the tip of the door glass 5 is pushed to the back side of the groove portion 15, the door glass 5 is formed in the groove portion 15 by the inclined surface in contact with the door glass 5 from the indoor side, as shown in FIG. Since the opposite side is easily tilted toward the inside of the vehicle with the tip of 5 as a fulcrum, the door glass 5 is attracted to the groove 15 in the rear vertical side portion 100B.

Further, when the door glass 5 is assembled to the groove portion 15, the door glass 5 abuts on the second connecting wall portion 32 and the first connecting wall portion 31 has a substantially V-shaped cross section in conjunction with the movement of the second connecting wall portion 32. When the door glass is bent so as to close the opening, stress is generated from the first connecting wall portion 31 having a substantially V-shaped cross section, so that the operator can grasp the position of the door glass 5 without visually observing the rear. Before the door glass 5 enters the groove 15 of the side vertical side portion 100B, the load of the door glass 5 can be temporarily deposited in the front side vertical side portion 100A, for example, the holding hand can be changed and the work status can be confirmed. As shown in FIG. 3, when the first connecting wall portion 31 bends so as to close the opening having a substantially V-shaped cross section, the other end 31b of the first connecting wall portion 31 comes into contact with the vehicle outer side wall portion 12. By doing so, it is possible to increase the stress from the first connecting wall portion 31 having a substantially V-shaped cross section.

Further, according to the present embodiment, the cross-sectional shape of the second connecting wall portion 32 is partially curved to form a substantially mountain-shaped cross section, but as shown in FIG. 6, the main body portion of the first connecting wall portion 31 is formed. The other end 31b on the opening side of the car 10 may extend substantially linearly from the other end 31b to one end of the car inside side wall portion 11 without providing a partially curved portion.
According to this, when the door glass 5 comes into contact with the second connecting wall portion 32, the second connecting wall portion 32 overlaps the side from the top portion 31c to the other end 31b of the first connecting wall portion 31, and then the first The substantially V-shaped opening of the connecting wall portion 31 bends so as to be completely closed, which also provides sufficient clearance when assembling the door glass 5 to the glass run 100A.

Further, even if the door glass 5 may collide with the connecting wall portion 30 while the vehicle is running after the door glass 5 is assembled, in the present embodiment, the connecting wall portion 30 facing the tip of the door glass 5 A cushioning function is exhibited by the first connecting wall portion 31 and the second connecting wall portion 32 that allow the glass to bend.

Further, according to the present embodiment, a sliding door vehicle of a type in which a substantially rectangular door glass 5 is attached to a front vertical side portion 100A and a rear vertical side portion 100B which are erected substantially parallel to the front and rear of the vehicle.
