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 in which a glass plate is fitted and mounted, and between glass plates or between window frames and glass plates.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, a glass plate 10 is fitted as a zipper gasket for a window frame for fitting and attaching a glass plate and sealing between the glass plates or between the window frame and the glass plate. One or two U-shaped glass plate fitting grooves 21 are provided, and the H-shaped (or Y-shaped) cross section is formed in an H-shape (or Y-shape). The zipper gasket 20 is provided with a glass plate fitting groove 21.
Is easily deformed, the glass plate 10 is easily fitted, and after the glass plate 10 is fitted, the lock is fitted with a star-shaped lock strip 30 that makes the glass plate 10 difficult to deform and prevents the glass plate 10 from coming off. A strip fitting groove 22 is provided, and small lips 23, 23 for strengthening the gripping force of the glass plate 10 are formed in the glass plate fitting groove 21, and the opening is narrowed so as to prevent the glass plate 10 from coming off.

However, since the window frame zipper gasket 20 is made of CR or EPDM rubber,
Although the frictional resistance when inserting the glass plate 10 is large and the depth of the glass plate fitting groove 21 is slightly larger than the insertion depth of the glass plate, the workability of inserting and mounting the glass plate is improved. Is bad.

[0004]

The problem to be solved is that the conventional window frame zipper gasket 20 has a large frictional resistance when the glass plate 10 is inserted, and the depth of the glass plate fitting groove 21 is large. Is slightly larger than the insertion depth of the glass plate, but the workability of inserting and mounting the glass plate is poor.

[0005]

SUMMARY OF THE INVENTION According to the present invention, one or two U-shaped cross-sections into which a glass plate is inserted and mounted, and a glass plate 10 for sealing between the glass plates or between the window frame and the glass plate are fitted. Lock strip 3 having a star-shaped cross section for providing a glass plate fitting groove 21 and preventing the glass plate 10 from coming off.
A zipper gasket 20 for a window frame made of a rubber-like elastic body formed by extruding a H-shaped or Y-shaped cross section as a whole. A thin layer 40 of PTFE, polyethylene or the like is formed on at least the inner bottom surface of the inner wall 21 except for the small lip 23 and the surface opposite to the end surface of the glass plate and the surface opposite to the lock strip fitting groove 22. Things.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
Is a glass plate, and 20 is a zipper gasket for a window frame made of a rubber-like elastic body into which the glass plate 10 is to be fitted. The zipper gasket is manufactured by extruding an H-shaped or Y-shaped cross section as a whole. It is configured as follows. 21 is the glass plate 1
One or two U-shaped cross-section glass plate fitting grooves into which 0 is fitted, 22 a lock strip fitting groove into which a star-shaped lock strip 30 for preventing the glass plate 10 from coming off, and 23 and 23 A small lip 40 protrudes so as to narrow the opening of the glass plate fitting groove 21.
A thin layer of PTFE, polyethylene, or the like formed on the inner wall of the glass plate 10, for example, as shown in FIG. Formed on the opposite side. Note that P
A thin layer of TFE, polyethylene, etc. may be manufactured as a zipper gasket, which may be attached separately. It can be integrated by vulcanization molding together, or the PTFE sheet can be integrated by hot melt.

The operation will be described. The charging process of the glass plate 10 will be described with reference to FIG. 5. The glass 10 is inserted in the Pa direction, and then set while moving in the Qb-Qa direction while checking the balance in the Pa-Pb direction. . The glass plate fitting groove 21 is easily deformed when the star-shaped lock strip 30 is pulled out, and the small lips 23, 23 narrowing the opening thereof are also easily deformed. In addition, the inner wall of the glass plate fitting groove 21 is formed. Further, as described above, the thin layer 40 of PTFE / polyethylene or the like is formed, and when the glass plate 10 is fitted into the glass plate fitting groove 21, the frictional resistance is significantly reduced. Insertion and mounting are significantly easier, and the workability is significantly improved. Moreover,
When the lock strip 30 is fitted into the lock strip fitting groove 22 after the glass plate 10 is fitted, the main body becomes difficult to deform this time. The lips 23, 23 are bent and deformed, and adhere closely along the glass plate 10, so that the glass plate 10 and the zipper gasket 20 are sufficiently sealed. Therefore, in such a state, even if a small amount of dust or foreign matter adheres to the surface of the glass plate 10, it is possible to perform a rain seal.

[0008]

[Effect of the Invention] Since the present invention is configured as described above,
Since the frictional resistance when the glass plate 10 is fitted into the glass plate fitting groove 21 is remarkably reduced, the glass plate 10 can be fitted more easily.
It has good conformability and close sealing property with the glass plates 10 of 3, 23, and even if a small amount of dust or foreign matter adheres to the surface of the glass plate 10, it is possible to seal after rain.
