Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an improvement in a synthetic resin end cap that is fitted onto the upper end of a partition sash that defines a glass opening of an automobile door.

BACKGROUND ART FIG. 5 shows, for example, a left rear door 1 of an automobile, and a partition sash 2 has a glass opening surrounded by a main sash 3 fitted into an opening for a door glass 4 that can be opened and closed. It is arranged along the vertical direction to separate the opening for the partition glass 5 which is in a dead state, and its lower end is fixed inside the door panel 6, and its upper end is connected to the main sash 3 in a T-shape. Connected and fixed.

FIG. 6 is an exploded perspective view showing the sealing structure at the upper end of the partition sash 2 at the connection part with the main sash 3 (section A in FIG. 5). A glass run fitting groove 9 and a gasket fitting groove 10 are provided to hold the glass launch channel 7 whose edges are in sliding contact and the gasket type weather strip 8 which clamps and fixes the partition glass 5 back to back to each other. It has a substantially H-shaped cross-sectional shape. Then, an L-shaped bracket 12 is fixed to the gasket fitting groove 10 side surface of the central partition wall 11 by welding or the like, and is attached to the main sash 3 via a screw (not shown) that is screwed into the screw hole 12a. ing.

Here, between the upper end of the partition sash 2 and the main sash 3, there is a partition sash 2.
Synthetic resin end cap 13 fitted to the upper end
are held in place to create a seal between the two and improve their appearance.

Specifically, the end cap 13 covers the outer side end surface of the partition sash 2, covers the outer side spacer portion 14 which is clamped between it and the main sash 3, and covers the end surface of the partition sash 2 on the side of the passenger compartment. In addition, a spacer portion 15 on the vehicle interior side which is similarly pressed between the main sashes 3, and both spacer portions 14,
15, and the above partition sash 2
A partition wall part 16 is connected to the central partition wall 11 of the partition wall part 16, and the partition wall part 16 is connected to both sides of the partition wall part 16, and forms a substantially U-shape together with the lower part of the partition part 16, and fits into the glass run fitting groove 9 of the partition sash 2. leg portion 17,
18, and a substantially triangular side wall portion 19 that stands upright from the inner edge of the outer side spacer portion 14 to be orthogonal to the partition wall portion 16, and the upper edge of the partition wall portion 16 is The main sash 3 is thinned so as to be in elastic contact with the inner surface thereof, and a substantially rectangular notch 20 is formed in the upper part of the partition wall 16 on the compartment side.

On the other hand, a thin plate-shaped seal lip 21 is formed elongated in the vertical direction at the upper part of the glass launch channel 7 facing the partition wall 16 on the passenger compartment side, and a seal lip 21 in the form of a thin plate is formed in an elongated manner in the vertical direction. There is also a thin plate-like seal lip 22 on the top.
is formed to be elongated in the vertical direction. Both seal lips 22 are attached to the end cap 13.
In the assembled state, as shown in FIG. 7, their distal edges abut against each other through the notch 20, so that they are in close contact with each other.

That is, the side wall 19 of the end cap 13 on the outside of the vehicle prevents raindrops and car wash water from entering into the gap created at the boundary between the glass launch channel 7 and the gasket type weather strip 8 at the upper end of the partition sash 2. On the other hand, on the passenger compartment side, the glass launch channel 7 and the gasket type weather strip 8 are made substantially continuous by abutting both seal lips 21 and 22 to ensure sealing performance. There is.

Problems to be solved by the invention However, in the conventional configuration as described above,
Both seal lips 21 and 22 are molded with sufficient allowance for the vertical length of the notch 20 to avoid problems such as errors during assembly, and in the assembled state, the lower part of the seal lips 21 and 22 corresponds to the thickness of the partition wall 16. As a result, as shown in FIG. 7, a substantially triangular gap 23 was created between the lower edge 20a of the notch 20 and the lower edge 20a of the notch 20, as shown in FIG. Also, if both seal lips 2
Even if the lengths of 1 and 22 are made to match the length of the notch 20, if the seal lip 21 of the glass launch channel 7 is molded at the same time as the corner connection part, the lower edge of the notch 20 20
It is impossible to precisely form the edge in contact with a at right angles, and a gap 23 also occurs.

Therefore, when car wash water hits strongly from the side or rainwater is pushed in by wind pressure, the above gap 2
3, water sometimes seeped into the passenger compartment.

Means for Solving the Problems In order to solve the above-mentioned problems, the end cap of the partition sash according to the present invention has the lower edge of the notch where both the seal lips of the glass launch channel and the gasket type weather strip come into contact with each other. , it is characterized by being formed in a tapered shape that gradually becomes thinner toward the top.

Function: By tapering the lower edge of the notch,
Since there is no sudden step difference and the tip edge of the seal lip is not significantly deformed at the lower edge of the notch, the generation of gaps is prevented.

Embodiment FIG. 1 shows an embodiment of the end cap 13 according to the present invention, and since this embodiment has the same basic structure as the end cap shown in FIG. 6 described above, there are no particular differences. are given the same reference numerals, and duplicate explanations will be omitted.

That is, in the case of this end cap 13, the lower edge 20a of the approximately rectangular notch 20 provided in the upper part of the partition wall 16 on the passenger compartment side has a tapered cross-section with a mountain-shaped cross section that gradually becomes thinner toward the top. It is formed.

Therefore, in the assembled state, as shown in FIG.
1 and the seal lip 22 of the gasket-type weather strip 8 are gradually deformed along the tapered surface of the lower edge 20a of the notch 20, and a gap 23 (see FIG. 7) is not generated as in the conventional case. do not have. Note that the slopes on both sides of the lower edge 20a do not necessarily have to be straight, and may be gently curved.
Furthermore, as shown in FIG. 3 or 4, even if only the glass launch channel 7 side or the gasket type weather strip 8 side is sloped, the gap 23 created there can be reduced to the extent that it can be virtually ignored. is possible.

In addition, not only when the seal lip 21 of the glass launch channel 7 and the seal lip 22 of the gasket type weather strip 8 are butted together as described above, but also by slightly extending them in the longitudinal direction of the vehicle and overlapping them alternately for sealing. The present invention is also applicable to such a configuration.

Effects of the Invention As is clear from the above explanation, in the end cap of the partition sash according to the present invention, the close contact between the seal lip of the glass launch channel and the seal lip of the gasket-type weather strip is the same as that of the end cap partition wall. Since it is not obstructed by the thickness and the generation of a gap with the lower edge of the notch is prevented, it is possible to reliably prevent rainwater and the like from seeping into the vehicle interior.
