〔Example〕

Embodiments in which the glass plate fixing method of the present invention is applied to various window frames will be described with reference to the drawings.

What is Daigo? This example shows a case in which the present invention is applied to a rectangular window frame body.

FIG. 1 shows a perspective view of the window frame body 4. The frame plate 41 has a rectangular frame shape as a whole, and the glass mounting plate is installed by recessing the side and protruding horizontally from the frame plate 41. The window frame body 4, which includes a flange 42 that is thinner than the frame plate 41 and serves as a holding portion, is made of metal such as aluminum, stainless steel, or plated steel, or resin such as vinyl chloride resin or ABS resin.

A concave groove 43 is provided along the entire length of the flange 42 on the surface in contact with the glass plate on which the glass plate is placed. Window frame body 4
A through hole 4 is provided at one corner of the flange 42 in a continuous manner with the groove 43 of the flange 42.
Drill 4. The melting paper 5 is fitted into the groove 43 of the flange 42.

The melting paper 5 is connected to the heating wire 51 and the heating wire #! 51 and a covering portion 52 that covers the periphery thereof. The heating wire 51 is a nickel-column wire or an iron-chromium wire with a diameter of about 0.25++e.

The covering portion 52 is made of a thermoplastic resin such as vinyl chloride resin, polypropylene resin, or polyamide resin, or a thermosetting resin that has curing reaction adhesive properties and is rich in electrical insulation. The molten string 5 can be easily cut, and the covering portion 52 can be easily peeled off from the heating wire 51.

With this structure, the molten string 5 wound around a cone or the like is connected to a power source extending outside the window frame 4 along the entire length of the groove 43 provided in the flange 42 of the window frame 4. The length of the melted string 5 including the length of the section 53 is cut. The tip of the cut molten string 5 is inserted from the outside of the window frame body 4 through the through hole 44 into the inside of the window frame body 4, and inserted into the concave groove 4 of the flange 42.
3 along the entire circumference, and finally insert the end portion of the melted string 5 into the through hole 4 from the inside of the window frame body 4.
4 to the outside of the window frame body 4. The covering portion 52 is peeled off from the end of the melting string 5 outside the window frame body, leaving only the heating wire 51.

FIG. 2 shows the case where the glass plate 6 is placed and fixed on the flange 42, and FIG. 3 shows a sectional view taken along the line XX in FIG. 2.

A glass plate 6 is placed on the flange 42 of the window frame body 4 into which the melting string 5 is fitted. Then, the heating wire 51 at the end of the melting string 5 extending outside the window frame body 4 is connected to the power source 7. Switch 8 is energized with ONL to supply current to melting string 5. The covering portion 52 is melted by Joule heat. When the covering portion 52 is melted, it expands and is pressed against the lower surface of the glass plate 6 by at least the width of the groove 43, and at the same time, the groove 43 of the flange 42 is melted and filled with the resin.

At this time, the molten resin may overflow from the groove 43 due to the expansion of the covering portion 52, and the excess molten resin may push up the glass plate 6. In such a case, the glass plate 6 may be lifted and the window frame may be damaged. There is a risk that the positional relationship between the body 4 and the glass plate 6 will shift. Therefore, when the weight of the glass plate 6 is light, a load is applied to the glass plate 6 to prevent the glass plate 6 from slipping, and electricity is applied thereto.

When the switch 8 is turned off and left for a certain period of time to cool and solidify the molten resin, the glass plate 6 is fixed to the window frame 4 through the resin hairs filling the grooves 43.

In this way, the lower surface of the glass plate 6 is adhesively fixed to the flange 42 along the groove 43 using resin.

Finally, the connecting portions 53 at both ends of the melting string 50 protruding outward from the window frame body 4 are cut from the outer wall surface of the window frame body 4 to complete the attachment and fixing of the glass plate 6 to the window frame body 4.

In this case, the window frame material is made of resin.

Further, if the covering portion 52 of the molten string 5 is made of the same resin as the material of the window frame body 4, the groove 43 and the molten resin can be fused together; If the glass plate 6 or the window frame body 4 does not have adhesive properties, the adhesive portions of the glass plate 6 or the window frame body 4 are treated with a primer or the like in advance to impart adhesive properties.

For example, a molten string made of nichrome wire coated with vinyl chloride resin is provided on a window frame made of vinyl chloride. on the other hand.

A glass plate is prepared by applying a silane-based primer, which is an adhesive paint, to the adhesive part of the glass plate, and then overcoating it with a urethane-based adhesive. Then, the glass plate is placed inside the window frame body with the bonded portion of the glass plate coated with adhesive overlaid on the fused assembly of the window frame body. Then, after energizing at a voltage of 24 V for 5 seconds, the energization was terminated and left for 30 seconds. When we measured the adhesive strength of the window frame glass plate in this case, we found that the tensile strength was 2.
A good adhesive strength of 5 kg/d was obtained.

In addition, polyamide resin is modified into a thermosetting type that has curing reaction adhesive properties in the nichrome wire in the groove of the aluminum ring window frame body.
After arranging the molten string 5 coated with the adhesive, a glass plate was placed and electricity was applied for 8 seconds at a voltage of 24V, and then the electricity was turned off and left for 30 seconds.

After that, the adhesive strength between the window frame and the glass plate was determined by Oki 1.
Good adhesive strength was obtained with a shear strength of 17.3 kg/d. - This example shows the case of an automobile window glass, and a molding is used as the frame.

A recessed groove 22 is provided over the entire length of the portion that abuts on the upper surface of 0.

To fit the glass plate 6o into the recess 21 of the molding 20, first, the melting paper 5 is inserted into the groove 22 of the molding 2o, and both end portions of the melting paper 5 are placed at appropriate locations on the molding 20. It is pulled out to the outside through a through hole (not shown) that communicates with the groove 22 that is located in the hole.

After the edge of the glass plate 60 is fitted into the recess 21 of the molding 20, the heating wires 51 at both ends of the melting paper 5
is connected to a power source to supply current.

The covering portion 52 is melted by Joule heat, and the melted covering portion 52 is further cooled and solidified, so that the resin in the groove 22 of the molding 20 and the upper surface of the glass plate 60 are bonded to each other.

In this case as well, if the material of the molding 20, the covering part 52 of the fused paper 5, and the glass plate 60 do not have adhesive properties, the adhesive part of the glass plate 60 and the molding 2Q
