Description of the Related Art Double glazing not only exhibits excellent heat insulating and soundproofing properties, but also has additional functions such as solar shading and safety, so that energy saving and safety are emphasized. It is well suited to today's needs and is expected to be in great demand not only for business use but also for general household use.

[0003] The double glazing having such a function is attached by being fitted into a glass groove of a sash frame, which is a member to be attached, and is usually provided with a glazing channel to secure watertightly and securely. Need to be interposed.

FIG. 4 is an explanatory view showing a conventional example of a glazing channel used in this case, and FIG. 5 is a vertical cross-section when a double-layer glass is mounted on a sash frame using the glazing channel shown in FIG. It is explanatory drawing which shows a structure.

[0005] According to these figures, the entire glazing channel 1 has a substantially U-shaped cross section and is fixed to a peripheral portion including the end surface of the double-glazed glass G;
And the outer soft portion 3 and the hard portion 2 which are provided integrally with the side walls 5a, 5a when they are mounted in the glass groove 6 of the sash frame 5 and which are integrally formed on the side of the outer surface facing each other. And a soft lip portion 4 integrally provided on the side surface side.

For this reason, when the double glazing G is fixed to the glazing channel 1, a pressing force may be generated by the soft lip portion 4 interposed between the hard portion 2 and the double glazing G. As a result, the fitting between the glazing channel 1 and the double-glazed glass G can be improved.

[0007] Further, when the double-glazed glass G is mounted in the sash frame 5, as shown in FIG. 5, the top soft portion 3 a of the outer soft portion 3 in the interposed glazing channel 1 causes the sash frame 5 to be connected. Since the cushioning function and the sealing function can be simultaneously exhibited by covering the void surface 7 formed between the multilayer glass G, the airtightness and the watertightness between the sash frame 7 and the multilayer glass G can be achieved. And can be increased.

When the conventional glazing channel 1 shown in FIG. 4 is used, the outer soft portion 3 tends to wobble due to its softness, and it is difficult to perform high-precision cutting. For this reason, there is a trouble that a jig for fixing the outer soft part 3 is separately required.

When the glazing channel 1 is fixed to the double-glazed glass, the top soft portion 3a of the outer soft portion 3 is required.
However, there was a problem that frictional resistance was generated in trying to get into the contact portion with the glass surface in the above, so that it was not possible to feed smoothly.

Further, the multi-layer glass G having the glazing channel 1 fixed thereto is sash-frame 5 through the glass groove 6.
After mounting, the top soft portion 3a of the outer soft portion 3 bends and becomes difficult to settle, and there is also a problem that the repair work is required afterwards.

Further, when the sash shoji made by mounting the multi-layered glass G on the sash frame 5 receives a severe impact such as abutting against a door stop when the sash frame is opened and closed, the glass groove 6 of the sash frame 5 is opened. There is also a problem that the top soft portion 3a of the outer soft portion 3 gets into the inside.

The present invention has been made in view of the above-mentioned problems in the prior art, and provides more robust linearity to the glazing channel, so that the cutting work and the mounting work can be performed more smoothly than before. It is an object to provide a glazing channel for a double glazing that can be performed.

The specific shape is not particularly limited as long as it has the function of performing the above.

Next, the operation of the present invention will be described with reference to FIG. 2 taking the glazing channel 11 shown in FIG.

That is, the glazing channel 11
Is that the main soft part 22 constituting the soft part 21 is the hard part 1
Since it is fixed integrally with the bent portion 15 without swaying, excellent linearity is imparted to the whole as a result, without using a jig for fixing a soft portion which was conventionally required, Cutting can be performed with high accuracy.

In this way, the glazing channel 11 that has been cut and processed with precision as desired is first
The hard portion 12 is pushed in so as to be sandwiched between peripheral portions including the end surface of the multilayer glass G and fixed.

At this time, since the hard portion 12 has the soft lip portion 23 on the inner side 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 also has the soft lip portion. Due to the pressing force generated by the sealing member 23, the sealing property and the fitting property with the double-glazing glass G can be improved.

Further, since the bent portion 15 provided on the side wall portion 14 of the hard portion 12 is integrally connected with the main soft portion 22, the bent portion 15 is mainly used for fixing the hard portion 12 to the double-layer glass G. The so-called sneaking phenomenon that tends to occur on the side of the glass contact portion 22a of the soft portion 22 can be reliably prevented by being supported by the bent portion 15. Therefore, when fastening the hard portion 12 to the double-glazed glass G, the work can be smoothly performed without receiving unnecessary frictional resistance of the main soft portion 22. Note that such a sneaking-in prevention function is shown in FIG.
The same can be obtained by using the glazing channel 11 shown in (a) to (d).

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 attached. Press fit.

Further, the main soft portion 22 ensures that the gap surface 7 formed between the side wall 5a of the sash frame 5 and the multilayer glass G when the multilayer glass G is mounted on the sash frame 5 is ensured. Can be closed. Therefore, the multi-layer glass G is more preferably sealed when the soft sealing portion 24 is provided under a sealing structure excellent in airtightness and watertightness by the main soft portion 22 in the interposed glazing channel 11. It can be attached to the sash frame 5 under the stop structure.

Further, since the main soft portion 22 is integrally supported on the hard portion 12 side through the bent portion 15, the main soft portion 22 is mounted when the multilayer glass G is mounted on the sash frame 5. As a result, bending can be prevented from occurring, and as a result, it is possible to contribute to smooth mounting work by improving the fit and eliminating the need for subsequent correction work.

Further, even when the sash shoji made by mounting the multi-layer glass G on the sash frame 5 receives a strong impact such as abutting against a door stop when the sash shoji is opened and closed, the main soft portion 22 is folded. Since it is integrally supported on the side of the hard portion 12 via the curved portion 15, the main soft portion 22 does not sink into the glass groove 6 of the sash frame 5, and stable product quality is maintained. be able to.

[0037]

As described above, according to the present invention, when the double-glazed glass is mounted on the sash frame, the soft portion located at the portion that covers and seals the gap formed between the two is replaced with the hard portion. Because it is directly connected to the open end of the side wall part of the part and it is hard to wobble, it is possible to impart excellent linearity to the entire glazing channel, so that a jig for fixing a soft part that was conventionally necessary is used It is possible to perform cutting processing with high accuracy without any need.

Further, since the soft portion is directly connected to the hard portion side, when the hard portion is fixed to the double-layer glass, the so-called sneaking phenomenon is surely prevented and unnecessary frictional resistance is received. It is possible to proceed smoothly without any work.

Further, since the soft portion is integrally supported on the hard portion side, no bending occurs when the double glazing is mounted on the sash frame. It can contribute to smoothness.

Furthermore, even when the sash shoji made by mounting the double-glazed glass on the sash frame receives a strong impact such as abutting against a door stop when the sash is opened and closed, the soft part is located on the hard part side. As a result of being supported integrally, stable product quality can be maintained without troubles such as a soft portion getting into the glass groove of the sash frame.

On the other hand, when the open end of the hard portion is fixed to the soft portion along with the bent portion, it is possible to more reliably prevent the wobble that tends to occur in the soft portion and to support the hard portion on the side of the hard portion. Can be done. Further, when the soft portion is provided integrally with the outer surface of the side wall portion of the hard portion and has a soft seal portion that is in close contact with the sash frame side, a state excellent in cushioning action and sealing action can be obtained. And can be attached to the sash frame.
