BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass run that is fitted into a door sash of an automobile and performs a door glass lifting guide function and a sealing function.

0002

2. Description of the Related Art FIG. 6 shows a front door of an automobile, in which a door sash 2 is installed upright at the door waist portion W of a door body 1, and has a front side sash 2 that is tilted significantly backwards to match the shape of the opening of the vehicle body. The door glass run 3 is made up of an inclined side 2A, an upper side 2B, and a rear vertical side 2C, and a door glass run 3 is fitted and arranged within the open section of the door sash 2.
This guides the door glass 4 up and down and seals the periphery of the door glass 4.

The door glass 4 and the door sash 2 are arranged with a gradual curvature toward the passenger compartment as they move upward to match the eggshell shape of the side surface of the vehicle body. Therefore, when the door glass 4 is fully closed, The upper end of the door glass 4 tends to swing out toward the outside of the vehicle.

Therefore, as shown by the chain line in FIG. 6, the edge of the door glass run 3 is integrally molded at the corner of the boundary between the inclined side 2A and the upper side 2B of the door sash 2. A glass guide 5 that protrudes further outward is provided so that when the door glass 4 is raised and fully closed, the door glass 4
Even if it swings out to the outside of the vehicle, the glass guide 5 allows the glass guide 5 to properly guide the door glass run 3 by sliding it. This similar structure is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-150820.
It is shown in the publication No.

[0005]

As described above, the glass guide 5 protrudes outward beyond the edge of the door sash 2, which gives a sense of discomfort and is not desirable in terms of appearance.

On the other hand, apart from the purpose of preventing the upper end of the door glass from swinging out, for example, as shown in Japanese Utility Model Publication No. 2-34980, the door glass is installed at a position near the door waist on the vertical side of the door sash. A spacer is interposed between the outer lip of the door glass run and the base side wall, and the lower part of the door glass is pushed toward the passenger compartment by this spacer. A structure that suppresses the tendency of the door glass to move outward has been proposed, but with this structure, if the reaction force of the spacer is too large, the upper end of the door glass will move toward the passenger compartment during the upward movement of the door glass. It is conceivable that the spacer's reaction force may start to swing out, making it difficult to tune the spacer reaction force.

Therefore, the present invention is capable of suppressing the deflection of the upper end of the door glass in the vehicle width direction when fully closing the door glass to the minimum possible extent without impairing the appearance, thereby making it possible to perform the fully closing operation smoothly. The present invention provides a door glass run for an automobile that can be used.

[0008]

[Means for solving the problem] A base having a channel-shaped cross section, and an outer lip that is integrally molded by folding inward from the edges of both side walls and coming into close contact with the door glass.
In a structure in which a door glass run having an inner lip is fitted into a door sash, and the door glass run is guided up and down by the door glass run, the door glass run disposed on the vertical side of the door sash is A first spacer is provided near the door waist portion and is integrally molded between the outer lip and the base side wall to push the door glass toward the passenger compartment. A second spacer is provided which is integrally formed between the lip and the base side wall and which pushes the door glass toward the outside of the vehicle.

[0009]

[Operation] When the door glass is raised, the door glass passes through the first spacer area and is pushed toward the passenger compartment. When the second spacer is installed, the upper end of the door glass is pushed toward the outside of the vehicle, and the first and second spacers cause the upper and lower parts of the door glass to swing out in the vehicle width direction. is balanced and properly accommodated within the door glass run. Therefore, by regulating the deflection of the door glass on the vertical side of the door sash, the deflection of the door glass on the upper side of the door sash and on the sloped side of the door sash is also suppressed as much as possible. The galling phenomenon on the door glass run is avoided.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, the door glass run 3 fitted and arranged in the door sash 2 includes a base 6 having a substantially channel-shaped cross section, and side walls 6a, 6b of this base 6.
It has an outer lip 7 and an inner lip 8 which are integrally molded by folding inward from the edge of the inner lip.
These outer lip 7 and inner lip 8 are the door glass 4
By coming into elastic contact with the surface, the door glass 4 can perform a lifting guide function and a sealing function.

Here, the portion of the door glass run 3 disposed on the vertical side of the door sash 2, for example, in the case of the front door shown in FIG. Door waist part W of door glass run 3
A first plate is integrally formed between the outer lip 7 and the base side wall 6a at a nearby position and pushes the door glass 4 toward the passenger compartment.
spacer 9 is provided, and the door glass run 3
The inner lip 8 and the base side wall 6b are located near the upper end of the
A second spacer 10 is provided which is integrally molded between the two spacers and the second spacer 10 to push the door glass 4 toward the outside of the vehicle.

In this embodiment, the first spacer 9,
The second spacer 10 has an outer lip 7 and a base side wall 6.
a, and the grooves inside the inner lip 8 and the base side wall 6b are formed by integrally building up the required length in the vertical direction, and each of these building ups has a length of The pressure is gradually decreased from the center to the upper and lower ends, so that the regulator operating force does not suddenly become heavier when the door glass 4 is raised.

According to the structure of the above embodiment, the door glass 4
When the door glass 4 is raised, the door glass 4 passes through the portion where the first spacer 9 is provided, so that the door glass 4 is raised as shown in FIG.
As shown by the chain line trajectory, the door glass 4 is pushed toward the passenger compartment, but when the upper end of the door glass 4 reaches the area where the second spacer 10 is disposed, the upper end of the door glass 4 is now pushed toward the outside of the vehicle as shown by the chain line locus in the same figure, and the door glass 4 is balanced in its swing in the vehicle width direction at its upper and lower portions by the first and second spacers 9 and 10. As a result, it is properly accommodated in the door glass run 3 as shown by the solid line in the figure.

[0015] Therefore, by restricting the deflection of the door glass 4 in the vehicle width direction by the longitudinal side 2C on the rear side of the door sash 2, the swing out of the door glass 4 in the vehicle width direction is restricted by the vertical side 2C on the rear side of the door sash 2. The deflection of the edge of the door glass 4 in the vehicle width direction is also suppressed as small as possible, and the galling phenomenon of the door glass 4 against the door glass run 3 is avoided.

[0016] In the above embodiment, the first and second
The spacers 9 and 10 are both formed by building up the grooves inside the molded bases of the outer lip 7 and the inner lip 8, but in addition to this, as shown in FIG.
A spacer can be formed by integrally molding a protrusion from a or 6b toward the outer lip 7 or the inner lip 8.

[0017]

As described above, according to the present invention, when the door glass is raised, the first spacer of the door glass run pushes the door glass toward the passenger compartment at a position near the door waist portion on the vertical side of the door sash. , and then push the upper end of the door glass toward the outside of the vehicle using the second spacer at a position near the upper end,
Since the deflection of the door glass in the vehicle width direction can be balanced by these first and second spacers, the door glass can be properly held within the door glass run, and the longitudinal side of the door sash can By regulating door glass runout, the runout of the edge of the door glass in the vehicle width direction on the upper side of the door sash and the sloped side of the door sash is also suppressed to the minimum possible, thereby preventing galling of the door glass against the door glass run. can be eliminated.

Furthermore, unlike the conventional glass guide in which the glass guide is formed to protrude outward, there is no protrusion on the outside of the vehicle, and the appearance and quality can be improved.
