One or more soft partition walls 35 are interposed between the inner wall 5 and the side wall portion 13 of the hard portion 12, and the hollow portion 26 is divided into two or more compartments 36 by the soft partition wall pieces 35. This is the same as the glazing channel 11 shown in FIG.

The soft portion 21 in the present invention has a substantially U-shaped concave portion of the hard portion 12 for receiving the multilayer glass G and a buffering action between the multilayer glass G and the sash frame 5 and the hard portion 12. Between the rigid portion 12 and the multilayer glass G, and also prevents the multilayer glass G from falling out of the hard portion 12 and preventing the hard portion 12 from falling out of the sash frame 5. There is no particular limitation on the shape as long as it has the function of performing the above.

Next, the operation of the glazing channel 11 shown in FIG. 1A will be described with reference to FIG.
First, the hard portion 12 is pressed against the peripheral portion including the end surface of the multilayer glass G and fixed thereto.

At this time, since the hard portion 12 has the soft lip portion 29 on the inner surface of the side wall portion 14, the hard portion 12 can provide a buffering action between the hard portion 12 and the double-layer glass G, and can have the soft lip portion. Due to the pressing force generated by 29, the sealing property and the fitting property with the double-glazed glass G can be improved.

Further, since the support arm 15 provided on the side wall portion 14 of the hard portion 12 is integrally connected to the top portion 24 of the outer soft portion 22, the hard portion 12 is fixed to the double-layer glass G. In this case, the so-called sneaking phenomenon that tends to occur on the top portion 24 of the outer soft portion 22 can be reliably prevented. The function of preventing the penetration of the top portion 24 can be similarly obtained by using the glazing channel 11 shown in FIG.

After the glazing channel 11 is fixed to the multi-layer glass G in this manner, the multi-layer glass G is placed together with the glazing channel 11 in the glass groove 6 of the sash frame 5 to which the multi-layer glass G is to be mounted. Press fit.

At this time, the swelling portion 25 of the outer soft portion 22 constituting the soft portion 21 is formed by the side wall portion 5 of the sash frame 5.
As a result, the hollow portion 26 is pressed by being pressed against
7 comes into contact with the opposed side wall portion 14 of the hard portion 12, and the hollow portion 26, which is likely to be generated with long-term use.
Crush deformation can be reliably prevented.

The top portion 24 of the outer soft portion 22 forms a gap 7 formed between the side wall 6a of the sash frame 6 and the multilayer glass G when the multilayer glass G is mounted on the sash frame 5. Can be reliably closed.

Therefore, the double-glazed glass G is formed under the sealing structure excellent in airtightness and watertightness by the top portion 24 and the bulging portion 25 of the outer soft portion 22 in the interposed glazing channel 11. It can be mounted on the sash frame 5.

When the glazing channel 11 shown in FIG. 1 (c) is used, the hollow portion 26 can be formed as a result when the double-glazing glass G is mounted on the sash frame 5. Thus, a sealing effect excellent in airtightness and watertightness can be obtained.

On the other hand, when the glazing channel 11 shown in FIG. 3 is used, the bulging portion 25 of the outer soft portion 22 is pressed against the side wall portion 5a of the sash frame 5 and is pushed back. Can be held in contact with the inner surface of the opposed bulging portion 25, so that the hollow portion 26 can still maintain its shape without being crushed, and can be airtight. It is possible to obtain a sealing effect excellent in watertightness and watertightness.

When the glazing channel 11 shown in FIG. 4 is used, the hollow portion 26 is formed by interposing a soft partition wall 35 between the bulging portion 25 of the outer soft portion 22 and the side wall portion 13 of the hard portion 12. Can be partitioned into two or more compartments 36, so that the collapse of the hollow portion 26 can be more reliably prevented, and an excellent sealing effect over a longer period can be obtained.

[0036]

As described above, according to the present invention, at least the soft portion located on the side in contact with the sash frame is integrated with the hard portion such that a hollow portion is defined between the soft portion and the hard portion. Since the soft portion is brought into close contact with the sash frame by the cushioning property of the hollow portion, a sealing effect excellent in airtightness and watertightness can be obtained.

In the case where the hollow portion is protruded from at least one of the soft portion and the hard portion and is supported by an eave-shaped soft piece that abuts on the opposing surface when interposed, An excellent sealing effect can be obtained by reliably preventing crush deformation of the hollow portion, which tends to occur with use over a long period of time.

Further, when the hollow portion is divided into two or more compartments by one or more soft partition walls interposed between the hard portion and the soft portion, the collapse of the hollow portion is more reliably prevented. As a result, an excellent sealing effect over a longer period can be obtained.

When the multilayer glass is mounted on the sash frame, the open end of the hard portion is immersed in the soft portion that seals the gap formed between the sash frame and the multilayer glass. When the hard portion is fastened to the double-glazing unit, the so-called sneaking phenomenon, which is likely to occur in the soft portion located at the corresponding portion when the hard portion is fixed to the double-layer glass, can be surely prevented.
