Abstract

PURPOSE:To improve the preventiveness for the intrusion of water into the car interior by forming the glass run body so as to be curved towards the groove bottom of a bracket for the installation of the glass run onto a corner piece. CONSTITUTION:The glass run body 80 of a corner piece glass run 50 is formed in bending towards the groove bottom 10a of a bracket 10, and made flexible so as to be extended and contracted towards the groove bottom 10a of the bracket 10, and a plurality of bottom parts 80b are formed on the inside surface 80a. With such constitution, though the water which intrudes from between an outer lip 60 and a door glass 4 tends to turn towards the close adhesion part between the inner side lip 70 and the door glass 4, water is guided towards the bottom part 80b by the curved inner surface 80a. Therefore, the intrusion of water into the car interior is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of Application 7m Invention H1 This invention relates to a corner piece glass run that is attached to a corner piece provided at the front end of the door waist portion of a front door of an automobile.

Conventional technology As shown in Fig. 3, in an automobile, the front door 1
It is known that a corner piece 3 is provided on the door waist portion 2 of the 4trgk in order to attach a door mirror (not shown).

This corner piece 3 is normally equipped with a corner piece glass run to guide the leading edge of the door glass 4 up and down and seal it, but in the case of a stubble-less type automobile, it is installed as shown in FIG. 4. In some cases, a corner piece glass run 5 made of rubber or the like is integrally formed from the oblique front #1 portion of the corner piece 3 to the rear edge. This similar structure is disclosed in, for example, Japanese Utility Model Application No. 60-11222.

To explain this with reference to FIGS. 4 to 6, such a corner piece glass run 5t'
The rear part 5a of the corner piece glass run 5 integrally formed in a letter shape is provided with an outer lip 6, an inner lip 7, and a glass run main body 8 provided on both sides of the outer lip 6 and the inner lip 7 to form the door glass 4. A guide groove 9 is formed.

As shown in FIG. 6, the glass run main body 8 of such a corner piece glass run 5 has a U-shaped cross section that is attached to the periphery of the corner piece main body 3a and is covered from the inside and outside with piece covers 3b and 30. The structure of the bracket 10 is fc'M.

Problems to be Solved by the Invention The corner piece glass run 5 is in close contact with the outer lip 6, the inch side lip 7, and the door glass 4 to prevent water from entering from the outside of the vehicle. A small amount of water that has entered between the outer lip 6 and the door glass 4 flows along the inner surface 8a of the glass run main body 8, which has a U-shaped cross section, of the corner piece glass run 5. It has been pointed out that there is leakage from the space to the single room side.

Also, depending on the car model, the groove bottom 10 &
If the depth of the groove JjE1 of the bracket 10 of the corner piece glass run 5 is different, the depth of the bracket 10 of the corner piece glass run 5 must be changed even in one direction, which is a problem that makes it impossible to share parts as the number of car models increases. There is also.

Therefore, this invention has developed a corner piece glass that reliably guides water that has entered between the actuator side lip and the door glass downwards, preventing it from entering the passenger compartment, and that can accommodate a wide variety of car models. Provided by runners.

Means for Solving the Problem In a corner piece glass run that is attached to the periphery of a corner piece provided at the front end of the door waist portion of a front door through a bracket having a U-shaped cross section to guide the door glass up and down, the above-mentioned bracket is used. The main body of the glass run, which is attached to the groove of the bracket and has an outer lip and an inner lip on both side edges, is curved toward the bottom of the groove of the bracket.

Function Water that enters between the outer lip of the corner piece glass run and the door glass oozes out along the curved inner surface of the glass run body of the corner piece glass run, but water that enters between the outer lip of the corner piece glass run and the door glass oozes out along the curved inner surface of the glass run body of the corner piece glass run. Because it is guided downward and discharged before reaching the interior, it does not seep into the passenger compartment.

In addition, even if the distance to the groove bottom of the bracket to which the glass run body is attached changes depending on the car model, the curved glass run body can expand and contract according to the distance to the groove bottom of each bracket, making it suitable for increasing the number of car models. The same parts can be used.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals used for the same parts as those of the above-mentioned conventional takeover.

In Fig. 1, a corner piece glass run 5° is attached to the periphery of the corner piece main body 3a, and a groove 10b l: of a bracket 10 having a U-shaped cross section is covered from the inside and outside of the vehicle interior with piece covers 3b and 3c. This is the same as the conventional method.

Here, the glass run main body 8ot-r of the corner piece glass run 50 is curved in the direction of the groove bottom 10a of the bracket 10 and has flexibility to expand and contract in the direction of the groove bottom 101L of the bracket 10, and has an inner surface soa I: forms the trough 80b of the antinodal number.

An outer lip 60 and an inner lip 70''4r are integrally formed on both side edges of the glass run main body 80 formed in this way, and are sealed to the door glass 41 to guide up and down.

According to the structure of the above embodiment, water that has entered from between the outer lip ω and the door glass 4 due to capillary phenomenon, etc., and the inner lip 70 and the door glass 4 are closely attached along the inner surface 80a of the glass body (material). I try to go around to the club side, but
Since the inner surface 80m is curved, the distance between the inner lip 70 and the contact part of the door glass 4 is long, and water is guided downward by the trough 80b of the inner surface 80m, so water may not enter. The water is discharged before reaching the close contact part 1 between the inner side lip 70 and the door glass 4, and does not seep into the single room.

In addition, as shown by the chain lines in Figures 1 and 2, depending on the vehicle type, the distance to the groove bottom of the bracket 10 may be longer than 10 m.
Even when used at 0', the glass run main body 8
Since the bracket 100 can be stretched in the direction of the groove bottom 10a and mounted, it can be installed in a wide variety of vehicle models, and To parts can be shared.

Effects of the Invention As described above, according to the present invention, the corner piece is attached to the periphery of the corner piece provided at the door waist WAIIIT end of the front door via a bracket l having a U-shaped cross section, and guides the door glass up and down. In the glass run, the glass run main body, which is attached to the groove of the bracket and has an outer lip and an inner lip on both sides, is curved toward the bottom of the groove of the bracket, so that the outer lip and the door glass are connected to each other due to capillary action. Even if water infiltrates through the tight contact area, it has the excellent effect of guiding this water downward and reliably preventing it from leaking into the passenger compartment.

Furthermore, since the glass run main body can expand and contract even if the depth to the bottom of the groove of the bracket changes, it can flexibly respond to the increasing number of car models and has the effect of allowing parts to be shared.
