Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a sealing structure for a revolving window such as a triangular window of an automobile.

(Prior Art) Conventionally, as shown in FIG.
It is well known that a rotating window 3, commonly called a triangular window, is attached to a triangular portion of a window frame 2.

This revolving window 3 usually has a triangular window frame 8 formed by a vertical partition member 5 and two sashes 6 and 7, which partition the window frame 8 from a substantially square door glass 4.
A triangular glass 9 is supported rotatably around a rotation axis determined by two upper and lower rotation shaft members 10 and 11.

In the rotary window 3, a seal rubber 12 is supported along the inner circumference of the window frame 8, and this seal rubber 12 and inner and outer weather strips (not shown in FIG. 1) A seal is designed.

However, the sash 7 forming the lower side of the window frame 8 is simply fitted into the gap between the door outer panel and the door inner panel that define the window frame 2 of the automobile door 1.
There was a problem that dust inside the door body entered the room through the small gap between the door frame 2 and the window frame 2.

In order to solve this problem, Japanese Patent Publication No. 56-45804 discloses that the door inner panel is wrapped around the lower side of the sash 7, and the edge of the door inner panel is joined to the edge of the door outer panel. Accordingly, a door has been disclosed in which the sash 7 is surrounded from below to shield dust from entering from within the door body.

However, with this method, it is difficult to process the door inner panel, and the door outer panel must be joined to the window frame, which makes the joining work difficult.

Furthermore, with the above structure, it is difficult to process the upper edge of the trim mounted on the door inner panel.

(Purpose of the invention) The purpose of the invention is to prevent dust from entering the passenger compartment from inside the door body even if there is a gap between the window frame of the revolving window and the door inner panel that communicates with the inside of the door body. To provide a sealing structure for a rotating window that can securely seal and also allow easy processing of the upper edge of a trim.

(Structure of the invention) Therefore, in the present invention, a window frame is provided in the upper part of the door body formed by the outer panel and the inner panel, and the window frame is provided with a glass that rotates via a rotating shaft. , a sealing structure for a rotary window of an automobile in which a sealing rubber is provided around the entire circumference of the window frame, wherein a downwardly bent part is formed at the upper end of the inner panel, and the inner panel is bent downwardly. A trim that covers the inner panel is disposed on the front surface side of the panel, and this trim has a bent portion provided along the downward bent portion of the inner panel, and the inner panel of the seal rubber. The side surface on the panel side is formed to have a gap between the downwardly bent portion of the inner panel and the downwardly bent portion of the trim into which the downwardly bent portion of the trim can be inserted. In the natural state, the first lip curves upward, and in the natural state, the second lip curves downward, which are spaced apart in the vertical direction. The tip of the second lip provided above is elastically abutted against the lower part of the vertical surface portion in an upwardly curved state, and is curved downward when the downwardly bent portion of the trim is inserted through the gap. The present invention provides a seal structure for a revolving window of an automobile, characterized in that the trim elastically contacts the vertical surface of the downwardly bent portion of the trim in a closed state.

(Effects of the invention) According to the invention, since the first and second lips provide a double seal between the window frame of the revolving window and the door inner panel, dust from inside the door body is reliably sealed. Since it can be sealed, the sealing performance is improved.

Furthermore, the improved sealing performance eliminates the need for the door inner panel to enclose the lower side of the rotary window seal structure, making processing of the door inner panel easier and eliminating the need for joining it to the door outer panel.

In addition, a gap is provided between the side surface of the seal rubber on the inner panel side and the downward bent part of the inner panel to allow the downward bent part of the trim to be inserted.
The trim can be installed after the revolving window is assembled.
The alignment between the revolving window and the door glass can be adjusted without any trouble.

Furthermore, by making the first lip curved upward, the rotating window can be installed smoothly without the first lip interfering with the door inner panel, while the second lip is curved downward. By doing so, the downwardly bent portion of the trim can be inserted smoothly, and the rotating window and trim can be assembled smoothly as a whole.

Furthermore, since the first and second lips extending in the left-right direction are provided with an interval in the vertical direction, even if there are variations in assembly between the sash and the seal rubber or between the door panel and the can be easily absorbed to ensure sealing performance.

(Example) Hereinafter, embodiments of the present invention will be described in detail.

As shown in FIG. 2, which is an enlarged sectional view taken along line A-A in FIG. gap 16
The sash 7 forming the window frame 8 of the rotating window 3 is shown in FIG.
(See Figure 1) is loosely fitted into this sash.
A triangular glass 9 is rotatably supported on the inner periphery of (7), and a seal rubber 17 according to the present invention
is installed. In FIG. 2, the seal rubber 17 is shown in its natural state so that its original shape can be easily understood.

This seal rubber 17 has its outer circumference (lower part)
is attached to the sash 7, and the inner periphery has outer and inner seal edges 17 that elastically press against the periphery of the triangular glass 9 from the inside and outside.
a, 17b are formed. Further, on the outside of the seal rubber 17, there is a weather strip outer 20 that is integrally attached to a molding 19 that is fixed to the door outer panel 14 by a clip 18.
It is sealed by the seal pieces 20a and 20b. On the other hand, the inner surface 17s of the seal rubber 17 is
When the seal rubber 17 is installed, a gap 16a is formed between the door inner panel 15 and the downwardly bent portion 15a for inserting the upper end edge of the door trim 21 in a downwardly bent state. The sealing piece 22a of the weather strip inner 22 is integrally attached to the downward bent part of the door trim 21 inserted into the gap 16a along the downward bent part 15a of the door inner panel 15. be done. and,
The lower part of the inner surface 7s of the seal rubber 17 is curved upward in its natural state, and when the sash 7 is installed, it is further curved upward and elastically attached to the lower part of the downward bent part 15a of the door inner panel 15. In the natural state, the first lip 23 that comes into contact with the first lip 23 is warped downward, and when the door trim 21 is attached, the weather strip inner 22, which is attached to the downward bent part of the door trim 21, is bent further downward and elastically attached to the lower part of the weather strip inner 22. 2nd lip 2 that presses against
4 are integrally formed, and the bent portion 15a of the door inner panel 15 and the inner surface 17s of the seal rubber 17
The gap 16a between the two is doubly sealed by these first and second lips 23 and 24.

Therefore, the space inside the triangular glass 9, that is, the vehicle interior A, is completely sealed from the interior space B of the door body 13, and dust is completely prevented from entering from the interior space B.

Note that if a lip 25 is provided on the outer side surface of the seal rubber 17 as well, which contacts the inner wall surface of the weather strip outer 20, rainwater etc. can be removed from the door body 13.
It is preferable to provide another seal portion 17c, which is effective in preventing intrusion into the inside, and which cooperates with the upper seal piece 22a of the weather strip inner 22 at the upper part of the inner side surface.

In addition, for the door glass 4, as shown in FIG.
20'b, 22'a, and 22'b are provided to press against the inside and outside of the door glass 4 that is raised and lowered in the vertical direction, and to seal the inside of the door body 13 against rainwater etc. adhering to the door glass 4. I have to.
