Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zipper gasket for a window frame for fitting and attaching glass plates and sealing between the glass plates or between the window frames and the glass plates.

[0002]

2. Description of the Related Art Conventionally, as a zipper gasket for a window frame for fitting and attaching a glass plate or the like and sealing between the glass plates or the like, as shown in FIGS. These are provided with two fitting grooves 21 and 21 having a U-shaped cross section into which the fittings 10 and 10 are fitted, and having a H-shaped cross section.

A lock strip provided on the upper surface of a zipper gasket 20 for facilitating the fitting of the glass plate 10 or the like, and preventing the glass plate 10 or the like 10 from coming off after the glass plate 10 is fitted. A lock strip 30 having a star-shaped cross section is fitted into the groove 22 and pressurized, thereby generating a stress F to apply a sealing pressure to the glass plates 10 and the like.

[0004] The zipper gasket 20 may be manufactured by extruding CR or EPDM as a main body if the black zipper gasket 20 is acceptable, and may be manufactured mainly with a silicone rubber or a inside of the color body. CR or EPD
M, and the surface is coated with a color film such as CSM or CPE.

However, the conventional zipper gasket 20 requires a width D and a thickness E of, for example, a rubber material having a JIS-A hardness of 75 degrees in order to secure a sealing pressure on the glass plates 10 and the like. However, there is a problem that the thickness E has to be large, for example, 10 mm or more, and there is a limitation in design design.

[0006]

The problem to be solved is that the conventional zipper gasket 20 for a window frame has a width D and a thickness in order to secure a sealing pressure on the glass plates 10 and the like. E must be increased, and there is a limit in design design.

[0007]

A description will be given with reference to FIGS. In the present invention, glass plate or the like fitting grooves 21 and 21 having a substantially U-shaped cross section for fitting the glass plates or the like 10 are provided.
A window frame zipper gasket made of a rubber-like elastic body in which a lock strip 30 having a star-shaped cross section is fitted into a lock strip fitting groove 22 provided at the center of the upper surface. To
The core bars 40, 40 having at least a substantially L-shaped section are embedded.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the embodiments will be described. A zipper gasket for a window frame having a substantially H-shaped cross section as a whole, which is configured as follows.

That is, reference numeral 21 denotes a U-shaped cross section for fitting each glass plate 10 formed on both the left and right sides, and 22 denotes a star-shaped cross section for preventing each glass plate 10 from coming off. A lock strip fitting groove into which the lock strip 30 is fitted, which is formed at the center of the upper surface. 40, 40
Is a core bar having a substantially L-shaped cross section composed of two surfaces and embedded on both left and right sides of the lock strip fitting groove 22, respectively. The two surfaces are fitted with a glass plate fitting groove 21 and a lock strip fitting groove. 22.

The operation will be described with reference to the drawings. In fitting the glass plates 10, 10 into the glass plate fitting groove 21 of the zipper gasket 20, first, the glass plate 1, etc.
The lock strip 30 is removed in order to make the 0 easily fitted.

In such a state, a glass plate 1
The lock strips 30 are fitted into the lock strip fitting grooves 22 so that the glass plates 10 and 10 do not fall out of the grooves 21 and 21. When the zipper gasket 20 is pressurized, a stress G is generated in the zipper gasket 20. The stress G is transmitted through the metal cores 40, 40 to the glass plate 10, etc.
10, a higher sealing pressure is obtained as compared with the conventional example, and the width D and thickness E of the zipper gasket 20 can be reduced (the window frame is reduced) to improve the appearance, and the like. The degree of freedom in design design increases.

The grooves 21 and 10 of the glass plate 10 and the like 10 are provided.
The insertability into 1 is not impaired.

The core metal 40 having a substantially L-shaped cross section may be changed in direction as shown in FIG. 5 or may be partially supplemented as shown in FIGS.

[0014]

[Effect of the Invention] Since the present invention is configured as described above,
As compared with the conventional example, a higher sealing pressure can be obtained, the size of the window frame can be reduced, the appearance can be improved, and the degree of freedom in design design increases.
