Abstract

PURPOSE:To prevent gaps from being created between a panel and tip sections of holding lips by forming at least portions of tip sections of hook-like holding lips made of a hard elastic member in contact with the outside surface of a door sash panel end by use of a soft elastic member. CONSTITUTION:A substratum constituted with a bottom plate 5 made of a hard elastic member such as hard rubber or hard synthetic resin and side plates 6, 6 on the car outside and car inside and having a cross section of a near U-shape is coupled in a glass run channel coupling groove 2c formed with the car outside panel 2a and car inside panel 2b of a door sash 2. Tip sections 7', 7' of holding lips 7, 7 made of a hard elastic member such as hard rubber or hard synthetic resin and molded in a hook shape are molded with a soft elastic member made of soft rubber, sponge rubber, soft synthetic resin and their foamed bodies.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in glass launch channels for automobiles.

Conventionally, a glass launch channel for an automobile is generally formed on the inner periphery of the door sash portion 2Q') of the door 1, as shown in FIG.

Conventional glass lanchan Furukeyu, Utsukai 53-121
As disclosed in No. 25 and shown in FIG. 2, the glass launch channel formed by the outside panel 2a of the door stopper 2 and the inside panel 2b is covered with a hard material such as hard rubber or synthetic resin. It is composed of a bottom plate 5 made of an elastic material and a side plate 6゜6 made of an elastic material, and has a cross section of approximately U.
A letter-shaped base A is fitted. A hook-shaped retaining lip 7.7 integrally formed on the outer end of the side plate is latched onto the end of both panels 2a, 2b. 8, 8 are lips formed in the grooves of the side plates 6, 6, 9 is a door glass stopper formed on the inner surface of the bottom plate 5, and the sliding contact surface with the door glass 3 is flocked lO. 11 is the bottom plate 5 and side plates 6, 6.
A shallow slit is formed along the boundary between each corner. Further, reference numeral 12 denotes a holding stopper formed on the outside of the side plates 6, 6.

However, in the conventional glass launch channel, the hook-shaped retaining lips 7, 7- formed of a hard elastic material are attached to the side plates 6, 7-.
6, so that when this glass launch channel is locked to the ends of the panels 2a, 2b of the door sash 2, the retaining lips 7.7 are formed at the ends of the panels 2a, 2b. The panel fitting grooves 4, 4 formed by the side plates 6, 6 are inserted and locked, and the panel fitting grooves 4, 4 formed by the side plates 6, 6 are inserted and locked. Due to variations in the shaping of panels 2a and 2b, variations in the shaping of the glass launch channel, and changes in the shape of the bent portions of the panels 2a and 2b, the end of the retaining lip 7.7 may differ from the shape of the outer surface of the panels 2a and 21). You can follow
There was a point in the assembly where a gap was created in the part, impairing the sealing performance and making the part look bad.

The present invention has been made in order to eliminate the points between the conventional glass launch channels, and the present invention has been made in order to eliminate the points between the above-mentioned conventional glass launch channels. Provided is a glass launch channel in which the contact portion of the panel is formed of a soft elastic material such as soft rubber, sponge rubber, soft synthetic resin, or foamed material thereof, thereby preventing the generation of a gap between the panel and the tip of the retaining lip. It's about doing. The present invention will be explained in detail with reference to FIGS. 3 and 4. Note that the same parts as those in the prior art are given the same reference numerals and the description thereof will be omitted.

FIG. 3 shows a first embodiment of the glass launch channel of the present invention. The structure that is particularly different from the conventional glass launch channel shown in FIG.
7 is made of a soft elastic material such as soft rubber, sponge rubber, soft synthetic resin, and foam thereof. In addition, as a design change, a bent portion 13 made of a soft elastic material is added in place of the shallow slit formed along the corner boundary between the conventional bottom plate 5 and the side plates 6, 6.
13 is formed, the lateral roots 6, 6 are developed around the bent part, and the ml slides into sliding contact with the door glass 3 instead of the conventional flocked lO.
The surface treatment layer 14 is formed using a technique commonly used in the past.
The difference is that it is given in a different way.

Since the tips 7', 7' of the retaining lip 7.7 of the present invention are formed of a soft elastic material such as soft rubber, the panel 2a of the door sash 2 as shown in FIG.

The panels 2a, 2b are attached to the tips 7', 7' of the retaining lip 7.7, even if the panels 2b are intricately shaped as shown.
By shaping the outer garment surface so as to suppress it, the shape of the panels 2a and 2b can be closely followed, and the sealing properties of the parts can be improved. In addition, due to errors in the molding of the panels, errors in the molding of the glass launch channel, etc., the tips of the retaining lips act to press against the outer surfaces of the panels 2a and 2b, creating gaps in these areas. There is no damage to the appearance of the part where the glass launch channel is made.

FIG. 4 shows a second embodiment of the invention. Compared to the first embodiment of FIG. 3, the tip 7' of the retaining lip 7.7.

By enlarging the soft elastic part formed at 7', panel 2
The difference is that the followability for a and 2b is improved. With this topography, the sealing performance and followability are improved, and the tip parts 'I' and 7' are easily bent, so the work of fitting the ends of the panels 2a and 2b into the panel fittings @4 and 4 sex has improved. 12".

Reference numeral 12'' indicates a holding stopper integrally molded on the inner and outer surfaces 911I of the side plates 6 and 60. Reference numeral 16 indicates a bending portion formed in the center of the bottom plate 5 in place of the bending portions 13 and 13 of the first embodiment. It is.

As described above, since the holding stopper 12'' and the bent portion 16 are formed of a soft elastic material, the installation workability of fitting the glass launch channel into the glass launch channel fitting groove 2C is improved.

The present invention is constructed as described above, and the portion of the tip of the retaining lip that contacts the outer surface of the panel edge of the door sash portion is made of soft elastic material. It follows the shape of the external surface and improves the sealing performance of this part, and there is no gap between the retaining lip and the external surface of the panel edge as in the conventional case, and the r & fitting part of the glass launch channel is improved. It has the effect that it does not impair the appearance quality of the product.
