Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a window glass in a fixed window device for a vehicle or the like.

Conventionally, a method for fixing a window glass to a window frame of an automobile or the like through a weather strip is to attach a weather strip 1 to an inner circumferential groove 11 and an outer circumferential groove 12, as shown in FIGS. 1 and 2, for example. After forming the weather strip 1 into a substantially S-shaped cross section with an outer circumferential portion 13 and pasting the circumferential green 21 of the window glass 2 into the inner circumferential groove 11 of the weather strip 1, the creasing portion of the window glass 2 is filled and bonded. A nozzle 100 for injecting the sealer is inserted between the inner circumferential groove 11 of the weather stripper and the window glass 2, and while moving along the inner circumferential groove 11, the nozzle 100 is inserted between the inner circumferential groove 11 and the window glass. By filling the gap between the window glass 2 and the weather strip 1 with a sealer, the peripheral edge 21 of the window glass 2 and the weather strip 1 are bonded together in a liquid-tight manner.

In this conventional method, when injecting the sealer into the gap between the inner circumferential groove 11 of the weather strip 1 and the circumferential green 21 of the window glass 2, an operation is performed so that the injection amount is constant over the entire circumference of the window glass 2. As it is extremely difficult to do so, it is inevitable that there will be places where the amount of injection is excessive or insufficient, and if there is an excess, it will be necessary to clean the sealer that protrudes outside, and if there is an insufficient amount, water will leak. However, there were problems such as the need for additional work to detect water leaks and inject sealer, and the sealer injection work itself required a large number of man-hours.

The present invention has been made in view of these problems, and includes applying a pressure-sensitive adhesive tape to the bottom and at least one side of the U-shaped inner circumferential groove formed in the weather strip. By inserting the peripheral green of the window glass into the inner peripheral groove of the weather strip and iron-bonding the weather strip to the peripheral green of the window glass, the inner peripheral groove of the weather strip and the peripheral edge of the window glass become adhesive. The tape is compressed and deformed to fill and bond the gap, and then the flange part of the window frame is inserted into the outer groove of the weather strip iron-bonded to the circumference of the window glass, and the window glass is attached to the window frame. The purpose of the present invention is to provide a method for installing window glass that is attached to the side.

EMBODIMENT OF THE INVENTION Hereinafter, an embodiment in which the method of the present invention is applied to a fixed window of an automobile will be described in detail with reference to the drawings.

The pressure-sensitive adhesive tape 4 used in the method of the present invention is shown in FIG. It is formed into a scroll shape with a release paper 41 interposed therebetween.

A specific example of the pressure-sensitive adhesive is a butyl rubber adhesive, which is a semi-vulcanized material containing butyl rubber as its main component and a tackifier, an inorganic filler, a vulcanizing agent, and other additives. This is a sulfur molded product.Next, the method for attaching the window glass of the present invention will be explained with reference to FIGS. 3 to 5.

First, as shown in FIG. 5A, while rewinding the adhesive tape 4, attach the side of the adhesive tape 4 on which the release paper 41 is not attached to the entrance part 11a of the inner circumferential groove 11 of the weather strip. Have them face each other.

Next, as shown in FIG. is inserted into the inner circumferential groove turtle 1, and the adhesive tape 4 is bent into a U-shape and attached to the bottom surface 11b, side surface 11c, and turtle d of the inner circumferential groove 1 oven.

Next, insert the peripheral edge 21 of the window glass 2 sequentially from the closing part 11a of the inner peripheral groove 11 of the weather stripper, and immediately before the peripheral edge 21 of the window glass 2 reaches the pressure-sensitive adhesive tape 4, release paper 41 is inserted. By peeling off the pressure-sensitive adhesive tape 4 from the adhesive tape 4 and further inserting the peripheral edge 21, the pressure-sensitive adhesive tape 4 is compressively deformed within the gap between the inner peripheral groove 11 and the peripheral green 26 of the window glass 2, and fills the gap. Adhesive weather strips are iron-bonded to the periphery of the window glass 2 in a liquid-tight manner.

Next, the window glass 2 is attached to the window frame 5 by iron-bonding the outer circumferential groove 12 of the weather stripper, which is iron-bonded to the peripheral edge 21 of the window glass 2, to the flange portion 52 of the window frame 5.

The outer periphery 13 of the weatherstrip stove and the step 51 of the window frame 5
A suitable filler adhesive is injected into the gap between the two to maintain a liquid-tight seal. Note that the form in which the adhesive tape 4 is attached to the inner circumferential groove 11 of the weatherstrip layer is not limited to the U-shape of the above embodiment; It may be in an L-shape extending from the bottom side surface 11c, or may be an L-shape extending from the bottom surface 11b to the inner side surface 1d.

As described above, "the present invention applies pressure-sensitive adhesive tape to the bottom surface and at least one side of the inner circumferential groove of the U-shaped cross section formed in the weatherstrip, and then to the inner circumferential groove of the weather strip. By inserting the periphery of the window glass and iron-bonding the weather strip to the cylindrical edge of the window glass, the pressure-sensitive adhesive tape is compressed and deformed within the gap between the inner circumferential groove of the weather strip and the periphery of the window glass. Then, the flange part of the window frame is inserted into the outer circumferential groove of the weather strip attached to the periphery of the window glass, and the window glass is attached to the window frame. A method for attaching a window glass in a fixed window device of a vehicle, etc., in which the pressure-sensitive adhesive tape has sufficient adhesive strength, and the pressure-sensitive adhesive tape extends over at least two sides of the inner circumferential groove of a weatherstripping. In order to adhere to the window glass, the area between the green circumference and the inner circumferential groove is ensured in a liquid-tight manner.The pressure-sensitive adhesive tape has release paper attached to one side, so it can be applied from the side of the release paper. By pressing with a pressing tool, the other side of the pressure-sensitive adhesive tape is attached to the bottom side of the inner circumferential groove of the weatherstripping in a U-shape or L-shape, and the surrounding green of the window glass is attached to the inner circumferential groove. From the opening □, the pressure-sensitive adhesive tape is inserted without adhesion.Before the periphery of the window glass touches the release paper, peel off the release paper from the pressure-sensitive adhesive tape and place the periphery of the window glass with the pressure-sensitive adhesive tape. The work is extremely simple, and there is no need for correction work like conventional sealer injection work.
