Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run mounting structure.

[0002]

2. Description of the Related Art In a side door a of an automobile shown in FIG. 4, a glass run c is mounted on a sash b to guide a door glass d up and down. As a mounting structure of the glass run c, for example, as shown in FIG. 3, hooks e, e are provided at both ends of the glass run mounting portion of the sash b, and these hooks e, e are respectively engaged with the engaging grooves f, f of the glass run c. A combination is known (see JP-A-63-43823).

[0003]

In assembling the glass run c, first, the engaging groove f of the glass run c is engaged with the hook e on the lower side of the sash b, and then the glass run c is engaged with the hook e on the upper side. The glass run c is rotated while pressing the side surface so that the engaging groove f is engaged with the upper hook e.
Must be engaged. In other words, such an operation must be performed over the entire length of the glass run c, which requires a great deal of trouble.

[0004] In view of such circumstances, an object of the present invention is to provide a glass run mounting structure having excellent assemblability.

[0005]

According to the present invention, there is provided a sash having a glass run mounting portion provided with a locking portion at one end outside the vehicle body and a glass run mounting portion provided at the other end inside the vehicle body with the glass run mounting portion. A locking portion having a first guide surface, and further forming a second guide surface by partially raising the inner surface of the glass run mounting portion, while the glass run is provided with a first cover at the lower end of the base portion. A guide portion and an engagement groove, a second guided portion in the middle of the base portion, and a hook portion on the upper end of the base portion on the outer side of the vehicle body, and the first and second guide surfaces of the sash have first and second glass run portions. The glass run is pushed into the glass run mounting portion of the sash while the guided portions are in contact with each other, and the hook portion and the engaging groove are respectively engaged with the locking portions at both ends of the glass run mounting portion. .

A first seal lip may be provided at the upper end of the base of the glass run to bend and deform by being pressed against the second guide surface when the glass run is mounted.

[0007] A second seal lip may be provided at the upper end of the base of the glass run, the second seal lip extending on the opposite side to the first seal lip.

[0008]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a cross section taken along line AA of FIG.
In the figure, 1 is a sash, and the sash 1 is a plate 2
The glass run mounting portion 3 having a substantially L-shaped cross section is formed by roll molding. The glass run mounting portion 3 has a bent portion 4 formed at a side end of an upper wall 3a, and a lower end of a side wall 3b is bent into a substantially L shape to form a locking portion 5 and a first guide surface 6.
Is formed. The second guide surface 7 is formed by partially protruding the side wall 3b. Furthermore, the upper wall 3a
, A weather strip 8 is mounted, and the tip of the weather strip 8 is wound around the bent portion 4 to form a locking portion 9.

A glass run 10 has a first guided portion 12 and an engagement groove 13 formed at a lower end of a base portion 11 thereof. Further, the glass holding lip 14 extends obliquely upward from the lower end of the base portion 11, and the first and second seal lips 15, 16 extend from the upper end of the base portion 11 to the inside and outside of the vehicle body, respectively. is there. A horizontal wall 18 is provided near the upper end of the base portion 11 with a hook portion 17, and a glass holding wall 19 is provided at an end of the horizontal wall 18. A hollow portion 21 is formed by extending a seal bridge 20 from the tip of the glass holding wall 19 to the base portion 11. A second guided portion 22 is formed on a side surface of the base portion 11 opposite to the hollow portion 21. The first and second seal lips 15, 16 and the seal bridge 20 are formed of sponge rubber, and the other portions are formed of solid rubber.

When assembling the glass run 10 to the sash 1, first, as shown in FIG.
The glass run 10 is pushed up while the first and second guided portions 12 and 22 of the glass run 10 abut against the first and second guide surfaces 6 and 7, respectively, and the engagement grooves 13 and the hook portions 17 are respectively moved. Locking part 5 and hook part 9 of sash 1
May be engaged.

In this embodiment, since the glass run 10 is inserted into the sash 1 while being guided by the two guide surfaces 6, 7 of the sash 1, the insertion direction is stable, and the insertion is easily performed. In particular, when the glass run 10 is set as shown in FIG. 2, the first seal lip 15 is pressed against the second guide surface 7 and is bent and deformed. Since the distance between the guide surface 7 and the hook 9 is smaller than the distance between the guide surface 7 and the hook 9, the upper end of the glass run 10 smoothly passes through the gap.
When the insertion of the glass run 10 is started, the first seal lip 15 separates from the second guide surface 7 and is restored, and the second guided portion 22 comes into contact with the second guide surface 7, so that the hook is formed. The parts 9, 17 are engaged with each other.

Further, when the glass run 10 is mounted, the first and second seal lips 15 and 16 are in close contact with the side walls of the glass run mounting portion and the inner surfaces of the upper walls 3b and 3a, respectively. Even if there is a distortion or a dimensional error of the glass run 10, stable sealing performance can be ensured.

In the glass run 10 of this embodiment, when the upper end of the door glass 23 pushes up the seal bridge 20, the seal bridge 20 folds the glass holding wall 19 inward, and the front end of the glass bridge 10 touches the surface of the door glass 23. Although it is of a so-called flash surface type that smoothly connects, the present invention is not limited to this type of glass run.

[0015]

According to the present invention, when assembling the glass run, the glass run is placed in the glass run mounting portion of the sash while the first and second guided portions of the glass run are respectively brought into contact with the first and second guide surfaces of the sash. , The hook portion and the engaging groove only need to be engaged with the locking portions at both ends of the glass run mounting portion, respectively.
