Description

[Detailed Description of the Invention] The present invention relates to a glass run used for sliding windows of vehicles.

As shown in FIG. 1, a sliding window in a vehicle is held by a sash 1 and is provided with a glass run 2 having two parallel guide grooves.
A center sash 4 is vertically provided at the lap portions of the window glasses 3a, 3b.

Incidentally, this type of window glass is required to have good sealing properties with the glass run, but at the same time, it is also required that the sliding resistance when opening and closing the window glass be small and the operation be easy. Therefore, as shown in Fig. 2, there is a gap d ₁ between the guide grooves 2a and 2b and the upper end of the window glass.
, and a gap d ₂ is provided to make the lip 21 easier to bend. However, if rainwater or car wash water enters the gaps d ₁ and d ₂ from the edge of the window glass, etc., it will flow along the glass run. The flow may flow down from the upper end of the center sash 4 along the center sash 4 and leak into the room.

3 and 4 show a cover member conventionally used as a means for preventing water leakage. The cover member 5 has a box-shaped part 51 that is open at the lower end, and a fin-shaped part that extends from both sides of the box-shaped part 51. It consists of a flat plate part 52 that projects. The upper half of the box-like part 51 is fitted from below into a hole 22 provided at the center of the upper part of the glass run 2, and the upper end of the center sash 4 is fitted into the opening at the lower end of the box-like part 51. Then, the upper end portions of the sash 1, the cover member box-shaped portion 51, and the center sash 4 are fixed with screw members 53. According to this, the window glasses 3a and 3b have a wrap portion whose upper end surface is the flat plate portion 5.
2, and the upper end of the center suspension 4 is covered by the box-shaped portion 51, so that the center suspension 4
Prevents water from leaking into the tank.

However, the lower surface of the flat plate portion 52 and the window glass 3
Since the upper end surfaces of a and 3b are pressed against each other, the sliding resistance of the glass is large, reducing operability. On the other hand, in order to improve operability, the flat plate part 52 and the window glass 3 are
The contact pressure with a and 3b must be lowered, and the sealing performance is reduced.

Therefore, an object of the present invention is to provide a glass run that can prevent water leakage at the center sash without increasing the sliding resistance of the window glass.

The glass run of the present invention has a sealing member at the upper center opposite to the upper end of the center sash. This seal member is connected in series with the glass run, has an integral window glass guide groove that is continuous with the window glass guide groove of the glass run, and projects downward and fits over the upper end of the center sash. It has a fitting part for tightening. Furthermore, a recessed portion having a thin lower surface is provided on the upper surface of both the guide grooves and is recessed into the guide groove, and the lower surface of this recessed portion is in liquid-tight contact with the upper end of the window glass.

The details of the present invention will be explained below with reference to the embodiments shown in FIGS. 5 and 6.

As shown in FIG. 5, the sealing member 6 of the present invention is interposed at the center of the upper part of the glass run 2 and is formed continuously with the glass run 2. The sealing member 6 is formed by setting both ends of the upper center of the glass run 2 in a mold and casting rubber of the same material as the glass run 2. As shown in FIG. 6, a cylindrical fitting part 61 is formed at the center of the sealing member 6 and projects downward, and by fitting the upper end of the center sash 4, the sash is covered. Further, guide grooves 61a and 61b are formed on both sides of the sealing member 6 and open downward to guide the window glasses 3a and 3b. This guide groove 61
a, 61b are continuous with the guide grooves 2a, 2b of the glass run 2.

Furthermore, recessed portions 62a and 62b recessed into the grooves are formed on the upper surfaces of the guide grooves 61a and 61b.
The thickness of the lower surfaces of the recessed portions 62a, 62b is made thinner than that of the upper wall of the groove. As shown in FIG. 2, the upper surface of the guide grooves 2a, 2b of the glass run 2 and the window glass 3
Although a gap d ₁ is formed between the upper end surfaces of b (and 3a), the lower surfaces of the recessed portions 62a and 62b are connected to the guide grooves 61a of the sealing member 6 that are connected to the guide grooves 2a and 2b of the glass run 2. , 61b, and therefore come into pressure contact with the upper end surfaces of the glasses 3a, 3b as shown in FIG. Concave portion 62a,
There are gaps 63a, 63 between 62b and sash 1.
b exists. The seal member 6, which is thus formed in series with the glass run, is integrally connected to the sash 1 and the center sash 4 by means of a screw member 64. In addition, in FIG. 6, reference numeral 41 denotes a flocked hair provided on the side surface of the center sash 4 and slidingly contacted with the side surfaces of the glasses 3a and 3b.

However, the glass run 1 configured as described above
In this case, the sliding window glasses 3a and 3b have a continuous guide groove 2 between the glass run 1 and the sealing member 6.
a, 61a and 2b, 61b so as to be movable.

In the glass run of the present invention, even if rainwater or the like flows to the center along the groove of the lip 21 of the glass run, the sealing member 6 is fitted to the head of the center sash 4, and the window glass 3a , 3b are in pressure contact with the lower surfaces of the concave portions 62a, 62b, so that rainwater and the like are prevented from entering the vehicle interior. In the glass run of the present invention, the window glasses 3a and 3b
The upper ends are pressed against the lower surfaces of the concave portions 62a and 62b so as to push them up a little, so that good sealing performance is maintained. Further, since the concave portions 62a and 62b are thin and easily deformed, the window glass 3a,
3b, and is in close contact with the upper end surface of the window glass 3a,
Even if the slider 3b is moved with its upper end pushing up the concave portions 62a and 62b, the sliding resistance is small.

Furthermore, the sealing member 6 in the present invention can be easily formed by mold injection. Furthermore, conventionally, glass runs were formed into a series of ring-shaped items by extrusion molding, cutting to specified dimensions, and bonding both ends with adhesive. There were times when there was a hole, but
Glass runs joined via a sealing member formed by mold injection do not have such an adhesive portion, and the ends are vulcanized and bonded via the sealing member, so there is no risk of gapping occurring.
