Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a gasket for attaching a window glass to a window of a building.

[Prior Art] A surface having a groove for inserting a glass plate and a mounting ridge or a mounting groove on the opposite side of the groove, and extending left and right from the base of the mounting ridge or the inlet of the mounting groove. A string-shaped gasket for attaching the window to the inner peripheral surface of the window and attaching it to the window is known. This gasket was attached by fitting it into a groove or ridge formed in an annular shape on the inner peripheral surface of the window so that the mounting ridge or the surface extending from the mounting groove to the left and right is in contact with the inner peripheral surface of the window. After that, the glass plate is attached by fitting the edge of the glass plate into the groove for inserting the glass plate. As a material for this gasket, chloroprene rubber (CR) is used, which has been recognized as weather resistant for many years of use. However, this CR contains a rubber compounding agent such as an anti-aging agent in order to increase weather resistance and strength, so if it is put in contact with a wall finishing sheet such as wallpaper, cloth or vinyl sheet, it will prevent aging. There is a problem that a compounding agent such as an agent stains and discolors these sheets. Therefore, conventionally,
The wall finishing sheet and the gasket are separated from each other, and a finishing material made of wood, metal or other non-polluting material is applied between the wall finishing sheet and the gasket.

[Problems to be solved by the invention]

The present invention provides a window glass mounting gasket that can be installed by stacking a wall finishing sheet with a gasket, does not cause contamination of the wall finishing sheet, and can omit the installation of another finishing material between the wall finishing sheet and the gasket. That is the purpose.

[Means for solving problems]

In order to achieve this object, the present invention has a portion having a width of 5 mm or more from the edge overlapping the wall finishing sheet on the inside of the window of the gasket,
Or, the width of 5 mm or more from the edge overlapping with the wall finishing sheet and the thickness of 5 mm or more is chlorosulfonated polyethylene (CSM) or ethylene propylene rubber (EPM, EP) that does not contain contaminant
DM).

[Action]

CSM, E from the edge that overlaps the gasket wall finishing sheet
If the width of the PM or EPDM portion is less than 5 mm, contamination may leak from the overlapping portion of the CR portion of the gasket and the wall finishing sheet to the exposed portion of the wall finishing sheet and reach the portion visible from the outside of the wall finishing sheet. So CSM, E
The width from the PM and EPDM portions and the gasket edge is 5 mm or more. Similarly, when there is a gasket part made of CR in the thickness direction of the wall finishing sheet, the CMS, E
By forming the PM and EPDM portions, contamination leached from the CR portion is prevented from reaching the wall finishing sheet.

〔Example〕

FIG. 1 shows an embodiment in which the present invention is applied to a gasket called a YE type gasket.
Reference numeral 1 is a gasket made of CR, which has a substantially triangular cross section. A groove 2 for inserting a glass plate, the bottom of which reaches the center, is formed on the top of the triangle, and a mounting groove 3 is formed on the bottom opposite to the groove 2 for inserting the glass plate.
A locking projection 7 made of aluminum or the like is fixed to the inner peripheral surface 6 of the window, and a mounting groove 3 is fitted in the inner peripheral surface 6 of the window with its surface extending from the inlet to the left and right in contact with the inner peripheral surface 6 of the window. The edge of the glass plate 8 is fitted into the groove 2 for inserting the glass plate. Inner surface of window 6
A wall finishing sheet 9 is inserted between the gasket 1 and the inner peripheral surface 6 of the window on the indoor side. A long width w from the edge 10 of the gasket 1 that overlaps with the wall finishing sheet 9 along the overlapping surface to the inside of the edge 10 of the wall finishing sheet 9 is about 17 mm, and the thickness d from the surface of the wall finishing sheet 9 is about 6 mm. The part 5 is formed by CSM. Since the gasket 1 is string-shaped, it is made by extrusion molding. At this time, the portion 5 can be integrally formed by coextrusion. 4 is a zipper.

The second embodiment shown in FIG. 2 shows a case where the present invention is applied to a gasket generally called a Y-type gasket. In the case of a Y-type gasket, a mounting projection 3'is formed on the opposite side of the groove 2 for inserting the glass plate, and the inner peripheral surface of the window 6
The mounting projection 3'is press-fitted into the locking groove 7'formed in the above. The portion 5 of this embodiment also has a width w and a thickness d of 5 mm.
That is all.

The third embodiment shown in FIG. 3 shows a case where the present invention is applied to a modification of the Y-type gasket shown in FIG. In this embodiment, a step 11 protruding inward of the window is formed on the indoor side of the window inner peripheral surface 6. Step 11 is convex ridge 3'for mounting
It rises from the outside from the edge 1a on the indoor side of the surface extending from the base part to the left and right. A wall finishing sheet 9 is provided on the upper surface of the step 11 so as to extend from the inner surface of the indoor side, and the portion 5 is formed into a fin shape so as to overlap the outer surface of the groove 2 for inserting a glass plate with the upper surface of the wall finishing sheet 9. It is formed to project. And this part 5 has a width w of 5 mm or more from the edge 10 and a gasket 1
It is connected to the part consisting of CR. In this case, since CR is not continuous in the thickness direction, the thickness of the part 5 is 5 mm.
The following is also acceptable.

[Effect of device]

According to the present invention, it is possible to prevent the wall finishing sheet coming into contact with the gasket from being contaminated and simplifying the interior finish of the inside of the window.
