Description

[Detailed Description of the Invention] This invention relates to a glass launch channel for an automobile.

As a conventional glass launch channel of this type, for example, the fourth
There is something like the one shown in the figure.

That is, the base 1a of the glass launch channel 1, which has a U-shaped cross section, is connected to the door glass guide recess 3 of the door 2's sash 3.
a, has a seating part 1c that projects from both the inner and outer ends of the base 1a toward the window opening OP side, and comes into contact with the window opening OP peripheral part 3b of the recess 3a in the sash 3;
A lip lb protruding from the seating portion 1c into the recess 3a;
lb' comes into elastic contact with the door glass 4 to clamp and guide the door glass.

In addition, 5 has a glass launch channel 1 on the outer periphery of the satshu 3.
This is a door weather strip that is held in a similar manner.

However, in such a conventional glass launch channel 1, the amount of protrusion a of the seating portion 1c toward the window opening OP side is small, and therefore the insertion guide width of the door glass 4 is narrow. If the door glass 4 swings laterally when closing the glass 4, or if the installation is deviated in the horizontal direction due to uneven installation, or especially when driving at high speed, the glass 4 may be sucked outward due to negative pressure generated around the door glass 4. There is a problem in that the glass 4 may be unable to close due to the glass 4 being pulled out and displaced, thereby deviating from within the insertion guide width.

This problem of the glass 4 deviating from the insertion guide width is particularly noticeable in front doors.

That is, the window opening OP of the front door has a trapezoidal shape, and the door glass 4 has a similar shape that is slightly larger than the window opening OP.

Therefore, during the opening/closing of the door crow 4, the upper edge of the door glass 4 from the upper edge to the front edge is not guided by the sash 3, but only the rear edge and lower part of the front edge of the door glass 4 are guided by the sash 3.

Therefore, at the end of the rise of the door glass 4, the door glass 4
Make sure that the upper part of the front edge from the upper edge is in the concave part 3a of the sash 3.
This means that the door glass is required to be fully closed, but generally when the car is parked, unless the installation is very uneven, the door glass will close smoothly. However, when driving at high speed, the negative pressure generated around the door glass 4 causes the glass 4 to be sucked out to the outside (outside the vehicle), and this suction causes the upper part of the front edge of the door glass 4 to The insertion guide width of the sash 3 protrudes outside, and the glass 4 cannot be raised to the fully closed position, causing air leakage and rain leakage.

Therefore, it is necessary to greatly increase the protrusion amount a of the seating IC of the glass launch channel 1 over the entire area.
-16098 Publication Figure 2), but this not only narrows the window opening OP over the entire area and deteriorates side visibility, but also improves the appearance quality because the glass launch channel 1 protrudes from the door sash 3 over the entire area. The actual situation is that the amount of protrusion a of the seating portion 1c is made as small as possible, which is undesirable as it gives the user the impression of poor quality and poor installation.

The present invention has been devised by paying attention to these conventional problems, and aims to solve the above-mentioned problems.

In order to achieve this objective, the present invention includes a roughly U-shaped base that is fitted into the door glass guide recess of the door sash, and a glass run that protrudes toward the window opening from both the inner and outer ends of the base. A front frame along the front pillar of the door sash, comprising: a seating portion that abuts the peripheral edge of the recess on the window opening side; and a lip that projects into the recess from the rain seating portion and comes into elastic contact with the door glass that closes the window opening; Only at a portion corresponding to the upper end of the rain seat, the amount of protrusion of at least the outer seat of the rain seat toward the window opening side is enlarged compared to other portions, and from the protruding end of the enlarged protrusion, It is formed as a guide surface that extends smoothly over the lip and slides and guides the door glass into the door sash recess.

This will be explained below based on the drawings.

1 to 3 are diagrams showing an embodiment of this invention.

Note that parts that are the same as those in the prior art will be described with the same reference numerals.

First, to explain the structure, a sash 3 is erected on the front door 2, and a window opening OP is formed.

Satoshi 3 is a front frame part 3 along the vehicle front pillar (not shown)
A, a horizontal frame 3B along the vehicle roof site rail (not shown), and a rear frame portion 3c along the vehicle body center pillar (not shown).

The glass launch channel 1 is made of rubber and includes a roughly U-shaped base 1a that is fitted into the four door glass guide portions 3a of the door sash 3, and a base 1a that protrudes toward the window opening OP from both the inner and outer ends of the base 1a, and is attached to the door glass guide 3a of the door sash 3. The seat part 1c contacts the window opening peripheral edge 3b of the recess 3a, and the rain seat 1c protrudes into the recess 3a and comes into elastic contact with the door glass 4 that closes the window opening OP. and lips lb and lb' for sealing between the two.

In the portion of the door sash 3 of this glass launch channel 1 corresponding to the upper end of the front frame portion 3A, the amount of protrusion A toward the window opening OP side of the seating portion 1c on the outside (outside of the vehicle) is set to the amount A of protrusion of other portions (conventional). The enlarged protrusion 6 has the same protrusion amount) and is smoothly continuous from the protruding end of the enlarged protrusion 6 to the lip 1b to form a guide surface 6a that slides and guides the door glass 4 into the door sash recess 3a. .

Regarding the method of forming the glass launch channel 1, conventionally extrusion molding was performed, but the area H including the enlarged protrusion 6 and its surrounding area is molded, and the other parts are extruded to form the molded part H. In addition, since the guide surface 6a of the door glass 4 is formed, it is necessary to provide the enlarged protrusion 6 with appropriate rigidity so that the glass 4 can be reliably guided.

As a means for this, for example, as shown in FIG. 5, the hardness of the seating portion 1c may be increased to form a rigid guide surface 6a of the enlarged protrusion 6, or the hardness may be maintained as is, and a steel plate may be used as shown in FIG. A core bar 7 such as the like is inserted.

With such a configuration, the seating portion 1 of the glass launch channel 1
In c, the protrusion amount A is partially large, and the insertion guide width B of the guide surface 6a of the door glass 4 is also large, so that the negative force generated around the door glass 4 when closing the door glass 4 during high-speed driving, for example. Even if the door glass 4 is sucked outward and displaced by the pressure, the door glass 4 does not deviate from the guide surface 6a and slides smoothly.

In this case, since the enlarged protrusion 6 is given rigidity, it will not be crushed.

Note that the amount of protrusion of the inner (vehicle inner side) seating portion 1c (naturally at the portion corresponding to the upper end of the door sash front frame portion 3A) can be made to protrude 6 larger than other portions.

In this case, even if a large wind pressure is applied to the glass 4 under strong winds and the door glass 4 is displaced inward (inward the vehicle interior) contrary to the above-mentioned suction, the door glass 4 can smoothly close without deviating from the guide surface 6a. be.

As explained in detail above, according to the present invention, the seating portion of the glass launch channel with the door sash is partially enlarged and protruded, so that the guide surface portion when the door glass rises becomes larger, and therefore the door glass deviates. This provides the effect that the closing operation will not become impossible.

Further, since the enlarged protrusion is formed only in a portion, side visibility is not impaired and the appearance quality is not impaired.

Furthermore, the number of parts to be installed is the same as before, so there is no loss in installation workability.
