Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the joint structure between a door sash and a partition sash in an automobile door.

As a rear side door of an automobile, for example, as shown in FIG. 1, a partition suspension 3 is attached to a door suspension 2 that constitutes the upper part of the rear side door 1, and the window panel of the rear side door 1 is opened and closed in front and behind this partition suspension 3. There is a type that is divided into a rear window panel 4 as a window and a partition panel 5 as a fixed window. In this type, the door sash 2 and the partition sash 3 are generally made of metal sash members, and if they interfere at the joint 6, the sash will rust, so recently, the joint between the two has been 6, and a waterproof sealing member is interposed in this gap to prevent rainwater, dust, etc. from entering, and to prevent deterioration in appearance.

As a conventional joint structure of this type of door sash 2 and partition sash 3, for example, the means described in Japanese Utility Model Publication No. 58-21768 is known.
As shown in FIGS. 2 to 4, the partition sash 3 is formed into a substantially H-shaped cross section, and an L-shaped bracket 7 is welded to the upper end of the partition sash 3 on the inner surface of the door sash 2. By screwing the bracket 7 to the bottom surface 9 of the fitting groove 8 formed along the rear window panel, the rear window panel is divided into an open/close type rear window panel 4 and a fixed type partition panel 5. Incidentally, during this installation, in order to prevent interference between the lower end edge 11 of the door sash 2 and the upper end 12 of the partition sash 3, a slight gap 13 is formed at the joint 6 of the two. And the rear window panel 4 is
Glass run rubber 15 is fitted and held in the fitting groove 8 of the door sash 2 and the front groove 14 of the partition sash 3 on the front side of the joint 6.
The partition panel 5 is supported so as to be movable up and down by a weather holder which is fitted and held in the fitting groove 8 of the door sash 2 on the rear side of the joint 6 and the rear groove 16 of the partition sash 3. The strips 17 are used to secure the ends.

And the above joint part 6 of the weather strip 17
A pair of seal portions 18 extending in the front horizontal direction are integrally molded with the weather strip 17 in the vicinity thereof,
This seal portion 18 is connected to the gap 1 in the joint portion 6.
3 to prevent interference between the door sash 2 and the partition sash 3, as well as to prevent water, dust, etc. from entering from the joint 6.

However, in the conventional joint structure described above, the seal portion 18 inserted in the gap 13 of the joint portion 6 is
The front part of the seal part 18 is only inserted between the door sash 2 and the partition sash 3, so if the tip of the seal part 18 is exposed to strong wind during high-speed driving, the hypothetical case shown in Figs. 2 and 4 As shown by the line, the seal portion 18 is pushed out to the outside of the joint and protrudes from the gap 13 of the joint 6. There are also problems such as the seal part 18 protruding outward from the vehicle causing wind noise, rainwater and dust entering through the gap 13 where the seal part 18 is removed, and degrading the appearance. Ta.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to solve the above-mentioned conventional problems by preventing the seal portion from protruding outward from the joint during high-speed running. It is about solving problems.

The gist of the present invention is a joint structure between a door sash that constitutes the upper part of a side door and a partition sash that divides the window panel of the side door whose upper end is fixed to this door sash in the longitudinal direction of the vehicle body. At the same time, a glass run rubber is attached to the sash section of the divided front window panel, and a weather strip is attached to the sash section of the rear window panel,
A seal portion extending rearward is formed integrally with the glass run rubber at a portion near the joint portion of the glass run rubber, and this seal portion is inserted between the seal portions formed at the joint portion of the door sash and the partition sash. Furthermore, the seal portion is provided with a hanging piece and an upwardly clamping piece, and the hanging piece is provided with a tongue portion extending from the side surface of the weather strip to the glass side at the end thereof.

The present invention will be described in detail below based on the accompanying drawings.

In the structure of the partition suspension shown in FIGS. 5 to 8, the partition suspension 3 is formed into a substantially H-shaped cross section as in the conventional case, and an L-shaped bracket 7 is welded to the upper end thereof. By screwing this bracket 7 to the bottom surface 9 of the fitting groove 8 formed on the inner surface of the door sash 2, the rear window panel 4 held by the glass run rubber 15 and the weather strip 17 are secured together. In addition to being divided into a partition panel 5 which is held together, a slight gap 13 is formed at the joint 6 between the lower edge 11 of the door sash 2 and the upper end 12 of the partition panel 5.

A channel-shaped glass run rubber 15 is attached to the fitting groove 8 of the door sash 2 and the front groove 14 of the partition sash 3 at the front side of the joint 6.
A clamping piece 28 is formed upright at the lower end of the door frame 5, and the clamping piece 28 and the side wall 29 of the glass run rubber 15 are clamped and fixed to the opening wall 30 of the door sash 2. In this type, the clamping piece 28 is also extended from the rear end of the upper side 15a of the glass run rubber 15 toward the corner member 23, and the sealing part 31 is formed by this extension part 32 and a hanging piece 33 integrally molded on the lower side thereof. configured. The hanging piece 33 is integrally molded on the rear side 15b side of the corner member 23. Further, a horizontal fitting piece 34 is formed at the lower end of the extension portion 32 to be inserted into the gap 13 in the joint portion 6 of the sash.

Therefore, in this structure of the partition sash, the gap 13 at the joint 6 can be closed by the clamping piece 28 near the rear end of the upper side 15a of the glass run rubber 15 and the extension 32 following this,
In addition to preventing the protrusion of the seal portion 31 during high-speed running, since the upper and lower sides of the gap 13 are covered with the extension portion 32 and the hanging piece 34,
Accordingly, the waterproofness and dustproofness of the joint part 6 can be improved, and interference between the sashes in the joint part 13 can be prevented.Furthermore, the tip of the seal part 31 is integrated with the glass run rubber 15. Since the wind is connected to the seal part 31, even when the vehicle is running at high speed, the wind that flows along the vehicle body flows backward along the outer surface of the seal part 31, and the tip of the seal part 31 is damaged by the wind as in the conventional case. The sealing function of the seal portion 31 can be fully demonstrated without being pushed out toward the outside of the vehicle body.

In addition, in the structure of the above partition chassis,
Although a structure has been described in which a pair of seal parts are provided on both sides of the glass run rubber 15 and the seal parts seal the joint part 6 on the outside of the vehicle interior between the door suspension 2 and the partition suspension 3, at least the joint part on the outside of the vehicle is sealed. It may be a structure.

As explained above, according to the joint structure of the door sash and the partition sash according to the present invention, the gap formed at the joint between the two can be separated by the clamping piece 28 of the glass run rubber and the extension piece 32 of the sealing part. Since it can be closed by the hanging piece 33, even when driving at high speed, there is no possibility that the seal part will be pushed out to the outside of the vehicle, and the sealing performance and appearance can be improved. In addition to being able to
It is possible to prevent situations such as the generation of wind noise due to the conventional seal portion.

Furthermore, by providing the extension piece 32 and the hanging piece 33, it is possible to cope with variations in the distance due to variations in the installation of the partition sash, parts precision, etc. Due to the extension, even if the extension piece 32 and the hanging piece 33 open, the space between them and the side surface of the weather strip can be covered, which improves the appearance and improves product quality. can.
