Abstract

(57) [Abstract] [Purpose] To provide a run channel capable of preventing wind noise generated when a door window glass of an automobile is slightly opened. In a run channel 11 attached to a sash 1 of a door, when a door window glass 7 is opened, a tip portion of one lip 15 is elastically attached to an inner surface 19 of an edge 18 formed on the other lip 17 side. The surfaces 21 and 22 are in close contact with each other to form a continuous surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a run channel structure capable of preventing wind noise when a window glass of an automobile is slightly opened.

[0002]

[Prior Art]

 FIG. 3 shows an example of a front door lantern structure shown in a cross section taken along the line AA in FIG. 2 showing the vehicle. This is disclosed, for example, in Japanese Utility Model Publication No. 52-4648.

Reference numeral 1 denotes a sash (window frame) of a door, a holding portion 2 is provided inside the sash, and a run channel 3 is attached to the holding portion 2.

The run channel 3 has an inner lip 4, an outer lip 5 and a middle lip 6. When the door window glass 7 is raised, the upper end surface of the door window glass 7 pushes the middle lip 6 to deform it. At the same time, the inner lip 4 and the outer lip 5 are brought into close contact with both side surfaces of the upper portion.

[0005]

[Problems to be solved by the device]

 By the way, in the above-described run channel structure door, there is a problem that a wind noise (whistle sound) is generated when the door window glass 7 is slightly lowered as shown in FIG.

When the cause of the wind noise is investigated, a vortex is generated in the cavity portion 8 when the air sucked from the inside of the vehicle to the outside of the vehicle passes through the corner portion 4a of the inner lip 4, and it collides with the outer lip 5. It turned out to be due to doing.

[0007]

[Means for Solving the Problems] The present invention was made on the basis of the above findings with the object of preventing the generation of wind noise when the window glass is slightly opened. In the run channel structure that is provided along the inner circumference of the sash and the inner and outer lips are attached to the inner and outer surfaces of the window glass when the window glass is closed, when the window glass is separated from the inner and outer lips. It is characterized in that the end portion of one lip is in close contact with the end portion of the edge portion formed on the other lip side so that these surfaces become a continuous surface.

[0008]

[Action]

 In the above run channel structure, vortices are generated because the surface along which the air flows is continuous even when air is sucked out of the passenger compartment with the window glass slightly open. Without it, the generation of wind noise is prevented.

[0009]

【Example】

 FIG. 1 is a cross-sectional view of the run channel structure according to the embodiment of the present invention, taken along the line AA of FIG.

Reference numeral 1 is a sash of a door, in which a channel 11 made of rubber, synthetic resin or the like is fitted in a groove thereof and attached by a clip or the like.

The run channel 11 includes an attachment portion 12 attached to the door sash 1, an inner side wall portion 13 extending inward (downward in the figure) from an end portion near the vehicle interior, and an end portion of the inner wall portion 13. The formed inner edge portion 14, the inner lip 15 extending from the inner edge portion 14 to the outer side in the width direction of the sash 1, and the outer wall extending inward (downward in the figure) from the end portion of the mounting portion 12 near the outside of the vehicle compartment. It comprises a portion 16, an outer lip 17 formed at the end of the outer wall portion 16, and an outer edge 18 formed integrally with the outer lip 17 and protruding toward the inner lip 15 side. .

The inner lip 15 is formed to be longer than the outer lip 17, so that the inner lip 15 has elasticity to rotate downward. That is, when the door window glass 7 is lowered and separated from the lips 15 and 17, the tip of the inner lip 15 is brought into close contact with the inner side surface 19 of the outer edge 18 so that the two are in a continuous state. . In this state, the surfaces 20, 21, 22 of the inner edge 14, the inner lip 15, and the outer edge 18 are continuous surfaces.

In the above run channel structure, when the door window glass 7 is closed, the inner lip 15 and the outer lip 17 are elastically deformed and adhere to the front and back surfaces of the door window glass 7 to prevent rain, sound, dust, and the like. It serves to prevent entry into the passenger compartment and to prevent vibration of the door window glass 7.

When the door window glass 7 is opened, the tip of the inner edge 15 is in close contact with the inner surface 19 of the outer edge 18 and these are in a continuous state, and the cavity 23 is in a sealed state, Does not appear. The surfaces of the inner edge 14, the inner lip 15, and the outer edge 18 are continuous surfaces with very few undulations.

Therefore, even if the air is sucked out of the vehicle compartment with the door window glass 7 slightly opened, the air smoothly flows along the surfaces of the inner lip 15, the outer edge 18, etc., and swirls, No turbulence or the like occurs, and the generation of wind noise is prevented.

By devising the shapes of the outer edge 18 and the inner lip 15, the surface can be made substantially flush. Further, by making the surfaces of the inner lip 15 and the outer edge 18 steep, it is possible to make the air flow smoother.

Further, by adjusting the wall thickness of the relatively long inner lip 15 and the like, its elasticity can be adjusted. For example, the repulsive force is set to be weak, and the lifting operation of the door window glass can be performed. It is possible to improve the sex. The relationship between the inside of the lip and the edge and the outside thereof may be opposite to that of the above-described embodiment, and the outer lip may be extended toward the passenger compartment.

The run channel according to the present invention is applicable not only to the one attached to the sash of the door but also to all the windows opened and closed by the window glass.

[0019]

[Effect of the device]

 According to the run channel structure of the present invention, when the window glass is opened, the lip and the edge come into contact with each other to form a continuous surface, which causes turbulence or vortex in the air flow. This prevents wind noise when the window glass is opened a little.
