Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a door glass run to be mounted on a door sash of an automobile, particularly to a structure of a corner portion thereof.

[Prior Art] As shown in FIG. 1, a door glass run 4 is attached to a door sash 2 of an automobile door 1 along the inner circumference thereof. The portion of the door glass run 4 along the door sash corner portion A is a terminal end of an extruded material 4A attached along the horizontal portion of the door sash and an extruded material 4B attached along the vertical portion as shown in FIG. Connected by molding to form an L-shaped corner 3C.

The door glass run 4 has a substantially U-shaped cross section as shown in FIG. 4, and a seal lip for sandwiching the door glass 3 from both sides at both opening ends.
In addition to having 41, holding lips 42 that engage with the door sash 2 are provided at both corners. In the free state, the door glass run 4 has a cross-sectional shape with a wide open side as shown in FIG. 5, and is fitted into the door sash 2 so that the open side is sandwiched during mounting.

The retaining lip 42 serves to attach to the door sash 2,
At the same time, it has a sealing function. Therefore, the molding corner
Even at 4C, it is desirable to form a continuous holding lip from the viewpoint of sealing property. However, corner section 4C
Originally, it is difficult to fit into the door sash 2, and if a continuous holding lip is formed, the fitting work becomes more difficult. Therefore, as shown in FIG. 6, the holding lips 42 of both extruded materials 4A and 4B are extended. Only the short ribs 42a and 42B are provided, and most of the corner portion 4C does not have a retaining lip (rib).

[Problems to be solved by the present invention] In view of the above situation, the present invention is intended to improve the sealing property of a die-molding corner portion, and has a sealing property equivalent to that of a linear extruded material portion, Moreover, it is an object of the present invention to provide a corner structure of a door glass run that does not hinder the fitting into the door sash.

[Means for Solving the Problems] As illustrated in FIG. 2, the present invention has a holding lip 42 of a horizontal extruded material 4A connected to the outer surface on the horizontal side of the molding corner portion 4C. It is characterized in that the extending rib 42a is extended to the corner end, while the rib 42b on the outer surface on the vertical side is not extended and both ribs 42a and 42b are discontinuous.

[Operation and Effect] Since both ribs 42a and 42b are separated, there is no particular hindrance when the corner portion 4C is fitted into the door sash 2. Regarding the sealing property, even if water invades the side surface of the corner portion at the time of high-pressure car washing on the vertical side, there is no problem because the invading water drops downward along the door glass run. The sealability is particularly required on the horizontal side, and in the present invention, the rib 42a is extended to the corner end on the horizontal side so that sufficient sealability is secured.

[Embodiment] In the embodiment shown in FIGS. 1 to 5, a door glass run 4 made of solid rubber is attached along the inner periphery of the door sash 2 as shown in FIG. As shown in FIG. 2, the portion of the door sash 2 along the corner portion A has an end of the extruded material 4A along the horizontal portion of the door sash 2 (FIG. 1) and an end of the extruded material 4B along the vertical portion. Is an L-shaped corner portion 4C connected by molding.

As shown in FIG. 5, the extruded materials 4A and 4B have a substantially U-shaped cross section with a wide open side, and have seal lips 41 extending in opposite directions at both open ends. A retaining lip 42 projects from both corners. Further, notches 43 are provided on the inner surfaces of both corners to facilitate bending. Both extruded materials 4A, 4B
Are set in a mold with the ends facing each other at a right angle, and a rubber material is injected between the ends to connect at the corners 4C.

The molding corner portion 4C has ribs 42a and 42b on the side surface which is on the outer side of the vehicle when attached to the sash. The rib 42a is formed on the horizontal side of the corner portion 4C, and extends to the corner end on the extension line of the holding lip 42 of the extruded material 4A. The rib 42b is formed on the vertical side of the corner portion 4C, and is formed short on the extension line of the holding lip 42 of the extruded material 4B.
There are no ribs between the tips of 2b and they are discontinuous. In FIGS. 3 and 4, reference numeral 5 is a seal member that seals between the door sash 2 and the vehicle body.

Therefore, the corner portion 4C and the linear extruded material 4A (4B) of the door glass run 4 configured as described above sandwich the opening side having the seal lip 41 as shown in FIGS. 3 and 4, respectively. In the closed state, the channel-shaped door sash 2
Fit inside. Then, both holding lips 42 of the extruded material 4A (4B) are engaged with the door sash 2 to prevent it from coming off. The ribs 42a and 42b are pressed against the door sash 2 at the corner portion 4C. These retaining lips 42 and ribs 42a, 42b simultaneously provide a sealing action between the glass run 4 and the door sash 2. Both seal lips 41 sandwich the peripheral edge of the glass 3 from both sides when the door glass is closed.

However, in the corner portion 4C of the door glass run of the present invention, the rib 42a reaching the corner end is formed on the horizontal side thereof and is pressed against the inner surface of the door sash 2, so that it is sufficient for high pressure water such as when washing a car. A good sealing property is secured. Also, the corner section
Since the ribs 42a and 42b of the 4C are separated from each other without being continuous, when the corner portion 4C is pushed into the door sash 2, the ribs 42a and 42b may stick to each other and hinder the deformation of the corner portion 4C for pushing. There is no hindrance to the installation work of the corner section 4C.
