Description

Description: TECHNICAL FIELD The present invention relates to a glass run for a sliding window.

2. Description of the Related Art Some automobiles have a slide-type window glass attached to an opening provided on a vehicle body side, for example.

This example will be described with reference to FIGS. 2 and 3. A pair of slidable window glasses 3 is mounted on a side opening 2 of a vehicle body 1.

The window glass 3 slides along a glass run 4 attached to the peripheral edge of the side opening 2 of the vehicle body 1, especially a glass run arranged on the lower side. For example, the window glass 3 is configured as shown in FIG. I have.

That is, the glass run 4 has two concave portions 5 as a whole to accommodate two window glasses 3. The glass run 4 locks the weather strip 7 from the outside of the metal sash 6 and the inside of the sash 6. The glass run main body 8 is fitted.

The weatherstrip 7 is formed with a holding lip 9 for locking to the vehicle body and a seal lip 10 on the lower surface, while the glass run body 8 is formed with a guide lip 11 that is in close contact with the surface of the window glass 3.

Since the sash 6, the weather strip 7, and the glass run body 8 are composed of three parts, there is a problem that a sealing error may occur if a molding error or an assembly error occurs in each part. .

Further, since each part is manufactured separately, there is a problem that the manufacturing cost is increased and an operation of assembling each part is also required, which leads to an increase in cost.

Accordingly, the present invention provides a glass run for a sliding window that can be manufactured at low cost without causing a defective seal or the like.

Means for Solving the Problems A panel supporting portion that supports an edge of the window panel is
A core metal is formed of a hard rubber buried, and a holding lip to be locked to the vehicle body and a guide lip that is in close contact with the window panel surface are integrally formed of soft rubber on the upper portion of the panel supporting portion, respectively. A seal lip made of sponge rubber or soft rubber is integrally formed on the lower surface.

The entire structure including the cored bar is integrally formed to prevent the occurrence of sealing failure due to a molding error of each part.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG.

In FIG. 1, reference numeral 4 denotes a glass run, which is disposed below the side opening 2 of the vehicle body 1 and guides a window glass 3 as a pair of window panels.

The glass run 4 has a W-shaped cored bar 12 embedded in a glass support 13 as a panel support made of hard rubber, and protrudes from the upper edge of the glass support 13. A guide lip 11 made of soft rubber and in close contact with the surface of the window glass 3 is integrally formed so as to surround the metal core 12. Further, a holding lip 9 which is engaged with the mounting flange F of the vehicle body 1 is integrally formed of soft rubber near one side of the guide lip 11.

The glass support 13 and the guide lip thus formed
11 form recesses 5,5 for receiving the window glass 3.

A seal lip 10 made of sponge rubber or soft rubber that is in close contact with the panel P of the vehicle body 1 is integrally formed on the lower surface of the glass support portion 13.

Next, an example of a method for manufacturing the glass run 4 will be described.

First, a band-shaped metal plate (to be the core metal 12) is degreased, primed, and processed into a predetermined cross-sectional shape by roll forming or the like.

Then, after applying an adhesive to the surface of the cored bar 12, the adhesive is supplied to an extruder, and the glass support portion 13 and the guide lip are supplied.
11, the holding lip 9 and the sealing lip 10 are extruded and formed integrally with the cored bar 12. When a surface treatment agent is used, it is simultaneously applied through a die at the time of the extrusion. Thereafter, the glass run 4 is cut into a predetermined size, and if necessary, is subjected to bending.

Therefore, according to the structure of the embodiment described above, since each part is formed integrally at the same time, it is possible to maintain high product accuracy as compared with the related art in which each part is manufactured and attached separately, and it is attached to the vehicle body 1. In this case, the sealing performance with the vehicle body 1 can be ensured as set.

Further, since the glass support portion 13 is formed of hard rubber, the rigidity of the whole together with the metal core 12 can be secured, and the thickness of the metal core 12 can be reduced. On the other hand, the seal lip 10 made of sponge rubber or the like can sufficiently secure watertightness with the panel P of the vehicle body 1.

In this way, by forming each part with the most suitable material according to the function and integrally forming the whole by extrusion molding, the number of parts and the number of assembling steps can be reduced.

In particular, since the core metal 12 is buried, iron can be used without using a material that takes rust prevention into consideration, such as conventional sash, such as aluminum or stainless steel. This is advantageous in that the cost can be reduced.

Effect of the Invention As described above, according to the present invention, since the cored bar, the panel support, the holding lip, the guide lip, and the seal lip are integrally formed, a variation in dimensional accuracy due to an assembly error of each part occurs. And therefore,
There is an effect that the sealing property with the vehicle body and the sealing property with the window panel can be reliably maintained.

Further, since the core is buried inside, it is not exposed to rainwater or the like, and therefore, it is not necessary to take measures against rust on the core. As a result, it is not necessary to use expensive materials such as stainless steel and aluminum for the metal core, so that the cost can be reduced and the panel supporting portion is made of hard rubber or the like, which contributes to the improvement of rigidity. The overall thickness can be reduced by reducing the thickness.

Further, since each part is formed into a body, there is an effect that a significant cost reduction can be achieved by reducing the number of assembly steps and the number of parts.
