Description

The present invention relates to a glass run bracket mounting structure for fixing a glass run or a division bar in which a glass run is integrated to a door via a bracket.

Conventionally, as shown in FIG. 7, a division bar 50 is attached to the rear door 1 of an automobile between a door glass 10 that moves up and down and a fixed glass 20.
In a general division bar, a glass run to be slid on the door glass 10 is attached to the front side of the metal sash, and a sealing material peripherally contacted with the fixed glass 20 is attached to the rear side of the metal sash. However, as shown in FIG. 8, a rubber or resin division bar 50 in which a sash 30 and a glass run 40 are integrally molded and a core material 45 such as metal or polypropylene is embedded is known (for example,). See Patent Document 1).
A sealing material 25 that is in contact with the fixed glass 20 is fitted on the rear side of the sash 30, but the sealing material 25 is also integrally molded with the sash 30.

Such a division bar 50 is fixed to the door 1 below the belt line BL via the bracket 100. The bracket 100 is provided with a screw hole 105, and the bracket 100 is fixed to the door 1 by a screw (not shown).

Here, as a method of attaching the bracket 100 to the division bar 50, as shown in FIG. 9, there is a method of surrounding the division bar 50 with the bracket 100, but simply surrounding the bracket 100 has a weak fitting force and can be attached in a stable state. There is a problem that it cannot be done.

On the other hand, as shown in FIG. 10, there is also a method in which a groove 55 is formed on the inside of the division bar 50, the outside of the vehicle, or both, and the protrusion 101 provided on the bracket 100 is fitted into the groove 55. Since the groove 55 formed in the division bar 50 appears on the external surface, the appearance is poor, and there is a problem that the cost is high because a cover such as a garnish that hides the groove 55 is required.

On the other hand, not only the division bar 50 in which the glass run is integrated, but also when the glass run 60 is fixed to the front door 2 below the belt line BL as shown in FIGS. 11 and 12, the same bracket 200 is used. However, in this case as well, the attachment between the glass run 60 and the bracket 200 becomes a problem, and in the type in which the protrusion 201 provided on the bracket 200 is fitted into the groove 65 formed in the glass run 60, The presence of the groove 65 makes it look unattractive (see, for example, Patent Document 2).

The mounting structure of the glass run bracket according to the embodiment of the present invention will be described with reference to the drawings.
In this mounting structure, as shown in FIGS. 1, 2 and 9, a rubber (or resin) division bar 50 in which the glass run 40 is integrated is attached to the rear door 1 as a bracket for the glass run. It is fixed via 500.

The division bar 50 is fixed to the rear door 1 at two positions above and below the belt line BL via the glass run bracket 500. The glass run bracket 500 is provided with a screw hole 505 and is fixed to the rear door 1 by a screw (not shown).
The division bar 50 is the same as that shown in the conventional example (FIG. 8), and the sash 30 and the glass run 40 are integrally molded on the front side of the vehicle, and the core material 45 such as metal or polypropylene is embedded in the rear of the vehicle. On the side, a sealing material 25 that is in contact with the fixed glass 20 is fitted.
A car inner lip portion 41 extending inward (outside the car) and sliding into the inner side surface of the door glass 10 is provided from the inner end of the glass run 40, and the inner lip portion 41 is provided from the outer end of the glass run 40. A vehicle outer lip portion 42 that extends toward the side (outside the vehicle) and slides on the vehicle outer surface of the door glass 10 is provided.
The sealing material 25 may be integrally molded with the sash 30.

As shown in FIGS. 2 and 4, the glass run bracket 500 includes a grip portion 510 having a U-shaped cross section and a fixing portion 520 having a screw hole 505 at the center.
The grip portion 510 is composed of a connecting wall 513 that connects the vehicle inner side wall 511, the vehicle outer wall 512, and both side walls 511 and 512, and extends in the vertical direction to wrap the division bar 50. The vehicle inner side wall 511 and the vehicle outer wall 512 of the grip portion 510 are attached so as to face the vehicle inner side surface and the vehicle outer surface of the division bar 50 and to sandwich the division bar 50 by utilizing elastic force, respectively.
The end portion 511a of the vehicle interior side wall 511 of the grip portion 510 is formed to be curved from the inside of the vehicle toward the outside of the vehicle, extends to the base of the vehicle interior lip portion 41 and covers the entire interior side surface of the division bar 50, as shown in FIG. It has become like. On the other hand, the end portion 512a of the vehicle outer wall 512 of the grip portion 510 extends straight from the vehicle rear side toward the vehicle front side to the front of the vehicle outer lip portion 42 to the base portion, and abuts on the vehicle outer surface of the division bar 50. I support it.

Further, the central portion of the connecting wall 513 of the grip portion 510 is cut out, and the vehicle rear side of the vehicle inner side wall 511 and the vehicle rear side of the vehicle outer wall 512 connected thereto are also cut out, so that the weight can be reduced. At the same time, the gripping force for gripping the division bar 50 is concentrated on the end portion 511a side of the vehicle inner side wall 511 and the end portion 512a side of the vehicle outer wall 512.
The fixed portion 520 has a substantially rectangular shape, one end side of which is integrally molded with the rear side of the vehicle at the center of the inner side wall 511 of the vehicle of the grip portion 510, and the other end side extends to the rear side of the vehicle.

The inner side wall 511 and the outer wall 512 of the grip portion 510 are formed with claws 531, 532, 533, 534 that are bendable inward and pierce the division bar 50 when bent.
The two claws 531, 532 are separated from each other on the vehicle inner side wall 511 of the grip portion 510, that is, the two claw portions 533 are provided on the upper and lower sides of the vehicle inner side wall 511 and on the vehicle outer wall 512 of the grip portion 510. , 534 are also provided in a separated state, that is, on the upper side and the lower side of the vehicle outer wall 512.

The claws 531, 532, 533, 534 have an isosceles triangle shape, and the isosceles are cut out from the vertices 531a, 532a, 533a, 534a, and are bent inward around the bottoms 531b, 532b, 533b, 534b. By bending the vertices, the vertices 531a, 532a, 533a, and 534a are pierced into the division bar 50.

Further, the claws 531 and 532 provided on the inner side wall 511 of the vehicle and the claws 533 and 534 provided on the outer wall 512 of the vehicle have a direction of 90 degrees when bent (note that 90 degrees here is strict). Not only when the temperature is 90 degrees, but also when the temperature is about 90 degrees, the appearance is changed in consideration of variations.
That is, the claw portion 531 is formed above the inner side wall 511 of the vehicle, the bottom portion 531b thereof extends in the front-rear direction of the vehicle, and the apex 531a before being bent faces downward.
Further, the claw portion 532 is formed below the inner side wall 511 of the vehicle, the bottom portion 532b thereof extends in the front-rear direction of the vehicle, and the apex 532a before being bent faces upward.
Further, the claw portion 533 is formed above the vehicle outer wall 512, the bottom portion 533b thereof extends in the vertical direction of the vehicle, and the apex 533a before being bent faces the rear side of the vehicle.
Further, the claw portion 534 is formed below the vehicle outer wall 512, the bottom portion 534b thereof extends in the vertical direction of the vehicle, and the apex 534a before being bent faces the rear side of the vehicle.

When the claws 531 and 532 formed on the inner side wall 511 of the vehicle are pierced into the inner side surface of the division bar 50 arranged in the grip 510, the inner side wall 511 of the vehicle is pushed inward and then the claws 531 and 531 are inserted. The 532 is bent vertically inward (outside the vehicle), and the claws 531, 532 are pierced perpendicularly to the division bar 50 from the apex 531a, 532a side so as to return the expanded vehicle interior side wall 511 to its original position. ..
As a result, the movement of the division bar 50 in the vehicle vertical direction with respect to the glass run bracket 500 is restricted.

Further, when the claw portions 533 and 534 formed on the vehicle outer wall 512 are pierced into the vehicle outer surface of the division bar 50 arranged in the grip portion 510, the vehicle outer wall 512 is pushed outward and then spread out. The claws 533, 534 are bent vertically inward (inside the car), and the claws 533, 534 are moved from the apex 533a, 534a side to the division bar 50 so as to return the expanded car outer wall 512 to the original position. Stick vertically against it.
As a result, the movement of the division bar 50 with respect to the glass run bracket 500 in the vehicle front-rear direction is restricted.

FIG. 3 shows a state in which the claws 531, 532, 533, 534 are pierced by the division bar 50 in this way. In this case, the claws 513 to 534 are pierced vertically with respect to the division bar 50, but the effect can be obtained even when the claws are pierced diagonally.

Further, as a method of piercing the claws 531, 532, 533, 534 into the division bar 50, after the grip portion 510 of the glass run bracket 500 is made slightly larger than the division bar 50 and the division bar 50 is inserted into the glass run bracket 500. By sliding, it is also possible to pierce the claw portion 531, 532, 533, 534 that is slanted toward the division bar 50 side to be inserted in advance.
Further, only one of the inner side wall 511 and the outer wall 512 of the vehicle, for example, the claws 531, 532 formed on the inner side wall 511 of the vehicle are slanted toward the division bar 50 to be inserted in advance and inserted into the bracket 500 for glass run. After sliding the division bar 50 and piercing the claws 531, 532, the other car outer wall 512 is pushed out to the outside of the car, and then the claws 533, 534 are directed inward (inside the car) vertically (inside the car). Bend it diagonally (even diagonally) and pierce the claws 533,534 from the apex 533a, 534a side perpendicular to the division bar 50 (even diagonally) so that the outer wall 512 of the car that has been pushed out is returned to its original position. You can also do it.

According to such a mounting structure of the glass run bracket, the movement of the division bar 50 with respect to the glass run bracket 500 in the vehicle left-right direction is restricted by gripping the division bar 50 from inside and outside the vehicle with the grip portion 510 of the glass run bracket 500. To.
Then, the claws 531, 532 formed on the inner side wall 511 of the vehicle are bent and pierced into the division bar 50 to regulate the vertical movement of the division bar 50 with respect to the bracket 500 for glass run, and are formed on the outer wall 512 of the vehicle. By bending the claws 533 and 534 and piercing the division bar 50, the movement of the division bar 50 in the vehicle front-rear direction with respect to the glass run bracket 500 is restricted.

Therefore, the glass run bracket 500 can be fixed to the division bar 50 in a stable state by using only one glass run bracket 500 having a simple structure such that the claws 513 to 534 are pierced into the division bar 50.

In the present embodiment, the bottom side portions 531b and 532b form the claws 531 and 532 in the vehicle front-rear direction on the vehicle inner side wall 511 of the grip portion 510, and the bottom side portions 533b and 534b form the vehicle vertical direction on the vehicle outer wall 512. Although the claw portions 533 and 534 are formed, conversely, the claw portions 533 and 534 may be formed on the inner side wall 511 of the vehicle and the claw portions 531 and 532 may be formed on the outer wall 512 of the vehicle.
Further, as shown in FIG. 5, the positions of the claw portion 531 and the claw portion 533 may be changed so as to intersect each other face-to-face. That is, the bottom side portion 533b may form the claw portion 533 in the vehicle vertical direction above the vehicle inner side wall 511, and the bottom side portion 531b may form the claw portion 531 in the vehicle front-rear direction above the vehicle outer wall 512.

Further, as shown in FIG. 6, the extending direction of the bottom portions 535b to 538b of the four claw portions 535 to 538 may be tilted by 45 degrees with respect to the vehicle front-rear direction. Here, it is assumed that the claw portion 535 and the claw portion 538 are oriented in the same direction, the claw portion 536 and the claw portion 537 are oriented in the same direction, and the bottom portion 535b of the claw portion 535 and the bottom portion 536b of the claw portion 536 are displaced by 90 degrees. ..

Further, the shape of the claws 531 to 538 is an isosceles triangle, but the shape is not limited to this, and any claw portion may be foldable and pierces the division bar 50 when bent.
Further, although two claws are formed on the inner side wall 511 of the grip portion 510 and the outer wall 512 of the vehicle, each of the two claws has an effect of restricting the movement of the division bar 50 with respect to the glass run bracket 500. ..

Further, in the present embodiment, an example in which the division bar 50 in which the glass run 40 is integrated is fixed to the rear door 1 via the glass run bracket 500 is shown, but as shown in FIG. 11, it is made of rubber or It can be applied to a glass run bracket for fixing the resin glass run 60 to the front door 2 (or the rear door 1).
