Abstract

PURPOSE:In a sashless door car, to improve sealing performance by extending the upper end of door weather strip along a corner piece then contacting resiliently against a body side weather strip and connecting the extended end to the glass run. CONSTITUTION:The front upper end of a door weather strip 30 is extended along the front side section 20a of a corner piece 20 and connected to the upper end section 8a of a glass run 8 fitted at the inside 20b of corner piece 20 and the extended section 30a. The extended section 30a is held by fitting the base section 30a1 in a groove 26b of cover 26 of corner piece 20. The leading end face 30a2 is contacted resiliently against a body side weather strip 12. Consequently it will be continuous from the door weather strip 30 to the glass run 8 through the extended section 30a while the extended section 30a and the body side weather strip 12 are sealed resiliently to improve the sealing performance.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a sealing device for a sashless door, such as a corner piece of a sashless door.

b. Prior Art An example of a conventional sealing device of this type is shown in FIGS. , the corner piece protruding from the front end of the waist part 2a of the door frame, 2 is the door window panel, and the part with the corner bead sedge is the inner part 4ta of the corner bead sedge.
It comes into contact with the glass run installed in the window, creating a seal between the corner bead sedge and the door window panel.

IQ is a door weather strip that is attached to the periphery of the door λ, and when the door is closed, comes into elastic contact with the periphery of the door opening of the vehicle body to seal between the door control and the vehicle body. top end to
0/2 is a body side weather strip attached to the periphery of the opening of the vehicle body above the door waist portion 2a via a retainer/lA. , the vehicle body comes into elastic contact with the periphery of the door window panel B,
I'm trying to seal it no matter what. In addition, in this body side weather strip/2, in the part corresponding to the 'L corner beesedge, the outer part 4tb of the corner beesedge is
I try to make it come into contact with the ball.

However, in such a sealing device, a portion A where the lower front end C1 of the corner bead sedge, the upper end 10EL of the door weather strip, and the body side weatherstrip t come together, and a portion where the outer part 4tb of the corner bead sedge and the glass run are Due to installation error or long-term use, a gap may occur in the B portion where the upper end fa and the body side weather strip /, 2 meet, and there is a risk that rainwater may leak and enter the vehicle interior.

Also, the top of Grass Run ♂? At A, the seal reaction force P is received from the seal and the body side weather strip/U, and as a result, the upper end of the glass run moves in the direction of the arrow (jll), and the gap at part B becomes thicker, allowing the fractionated water, etc., to further infiltrate. OBJECT OF THE INVENTION This invention has been made in view of the above-mentioned circumstances.
The purpose of this is to improve the sealing performance by preventing seal leakage from the part B and the part B.

d0 Structure of the Invention This invention extends the upper end of the door weather strip upward along the outer side of the corner piece, and extends the upper end of the door weather strip upwardly along the outer side of the corner piece, in order to improve the sealing performance around the door, especially around the corner piece. The weatherstrip extension is connected to the glass run at the end, and the weatherstrip extension is brought into elastic contact with the body side weatherstrip. To explain, the waist part 2 of Satsushi Resto Ako
There are 20 corner pieces protruding from the front end of a.

This corner piece 20 has a U-shaped steel plate body U welded to the door 2, and a glass run Z that is welded to the rear end of this body and 2 U, and comes into elastic contact with the front peripheral edge of the door window.
It consists of a channel grate 2tI to hold, and a cover U which is held in shape by a clear lug part 26a on the main body 22 and covers the main body 72 and the channel grate 2 from the inside and outside. (Well, ditch?
The front side unit Oa of the corner piece 20 where Jb is formed faces the body side weather strip 2 attached to the opening periphery of the vehicle body via a retainer 1A. Side Weather Shark, Trip 7.2 & i It is added to make elastic contact with the periphery of the door window panel B to seal between the vehicle body and each door window panel. A door weather strip that is attached to the periphery of the second door and comes into elastic contact with and seals the periphery of the opening of the vehicle body. Corner piece 2 with the front upper edge of 0 intact.
0's front stroke 1] extends upward along the section 20a, ? Oal,
, this extension? Oa and inner part 2cb of corner piece 20
The extension part 70a is connected to the upper end a of the glass run fitted to the corner piece 2.0 (specifically, a certain length λq), and the base part 30a1 of the extension part 70a is fitted into the dovetail groove 2Ab of the cover 26 of the corner piece 2.0. Is the tip held? Oa2
is made to come into elastic contact with the body side weather strip/2.

With this configuration, an extension from the door weather strip 30 to the glass run, ? The extension part 10a and the body side weather strip 2 are integrally continuous by Oa, and the sealing bodies elastically contact each other to seal the corner piece 20 and the door weather strip 2. 0 and the body side weather strip /, j is reliably sealed.

Furthermore, even if the seal reaction force P of the body side weather strip 12 acts on the upper end portion a of the glass run, the extension portion 1
0 Grass run due to a? The collapse of the seal is suppressed, no gaps are formed, and the sealing performance is reliably maintained.

FIG. 3 shows another embodiment.

In this example, the cover 21 of the corner piece 20 is divided into two parts, an outer cover 26' and an inner cover 2A", and is fixed to both force bars 46' and 24" with screws 3, and the extension part of the door weather strip 70 is ,? Base of Oa? Extension by pinching Oa1, ? I try to maintain Oa.

The cover 26 is fixed to the main body 2.2 by fixing the boss 26'a protruding from the outer cover 26' and the corner piece main body n with screws 7g.

10 Effects and More of the Invention According to the present invention, the practical effect of significantly improving the sealing performance around the door, especially around the corner piece, is achieved.
