Description

The present invention relates to a fitting that holds double glazing via a gasket.

In fittings that hold double glazing, such as sliding windows and sliding windows, fittings that incorporate double glazing in the glass holding groove of the stile material are known in order to improve heat insulation and sound insulation. (For example, Patent Document 1).
In the fitting of Patent Document 1, in the double glazing, spacers are arranged between a plurality of plate glasses, and the outer peripheral side of the spacers is further filled with a sealing portion seal (seal material between panels) to fix each plate glass. Further, a gasket (glazing channel) is attached to the outer peripheral portion of the double glazing, and the gasket and the double glazing are inserted into the glass holding groove to assemble the fitting.

The fitting of Patent Document 1 enters between the plate glasses and seals the gas between the plate glasses in order to prevent ignition by the gas when the sealing portion seal melts and burns due to heating and generates flammable gas. A heating expansion material was provided. Specifically, a configuration in which a heat-expanding material is fixed to the bottom surface of a reinforcing member incorporated in the glass holding groove and the heat-expanding material is arranged between the reinforcing member and the gasket, or between the gasket and the end of the glass. The configuration in which the heating expansion material is arranged is disclosed.

Japanese Unexamined Patent Publication No. 2013-19116

When the heat expansion material is placed between the reinforcing member and the gasket, the gasket is placed between the heat expansion material and the sealing portion seal, so that the gasket remains when the heat expansion material expands. If so, it prevents the heat expansion material from entering between the plate glasses. Therefore, the gasket may be cracked, and the flammable gas may flow out from the glass holding groove through the crack.

Further, when the heat expansion material is arranged between the gasket and the glass end, there is a problem that the type of gasket differs depending on whether or not there is fire resistance, and the management becomes complicated. That is, in the case of fittings that do not require fire resistance, the gasket is in close contact with the end of the glass. On the other hand, in the case of fittings that require fire resistance, the gasket needs a space for storing the heated foam material between the gasket and the glass end. Therefore, the structure of the gasket is different, the types of gaskets are increased, and management becomes complicated.

An object of the present invention is to provide a fitting that can quickly close the gap between glasses with a heated foaming material and can prevent an increase in the types of gaskets.

According to the present invention, since a plurality of openings are formed in the bottom surface of the gasket provided in the glass holding groove of the frame material, when the heated foaming material foams and expands, it enters the inside of the gasket through the openings. The outer peripheral surface of the double glazing can be covered with a heated foam material. Therefore, even if flammable gas is generated from the sealing portion seal, the gas can be sealed between the glasses, and ignition by the gas can be prevented. Further, since the gasket has an opening, even if the gasket remains, the sealing portion seal can be reliably and quickly covered with the heated foam material. Further, since the expanded heated foam material closes between the frame material and the glass, it is possible to prevent the flame from penetrating from the heated surface to the non-heated surface.
Further, since the heated foam material is arranged between the gasket and the stile material and not between the gasket and the double glazing, it is not necessary to change the type of gasket depending on the presence or absence of the heated foam material. Therefore, it is possible to prevent an increase in the types of gaskets and facilitate parts management.

On the other hand, in the lower stile 32, since the heated foaming materials 514 and 515 are not adhered to the prospective surface portion 321, the rainwater flowing into the lower stile 32 does not become an obstacle when flowing over the prospective surface portion 321 and the rainwater is used as the prospective surface portion It can be easily drained from the drain hole formed in 321.

(4) The vertical frames 33 and 34 are arranged not only on the heated foam material 516 arranged so as to face the opening 77 of the bottom surface portion 71 of the gasket 70, but also on the outdoor surface portion 72 and the indoor surface portion 73 of the gasket 70. Since the heated foaming materials 517 and 518 are provided, the total volume of the heated foaming materials 516 to 518 arranged between the gasket 70 and the vertical frames 33 and 34 can be increased. For this reason, even if heat warpage occurs in the vertical frames 33 and 34 and the gap between the outdoor finding piece 322 and the indoor finding piece 323 and the outdoor surface or the indoor surface of the double glazing 50 becomes large, the gap is formed. It can be closed by the heated foaming materials 517 and 518, and the fire prevention performance can be further improved.

(5) Since the heated foaming materials 511 to 518 are formed in the shape of a long tape, they can be easily adhered along the longitudinal direction of each of the frames 31 to 34.
Further, the opening 77 formed in the bottom surface 71 of the gasket 70 is a square hole, and a pair of long sides 771 along the longitudinal direction of the gasket 70, that is, the longitudinal direction of the stiles 31 to 34, and a pair of long sides orthogonal to the long sides 771. Since the opening 77 is formed by the short side 772, the area that overlaps the opening 77 in a plane can be increased when the tape-shaped heated foam materials 511 and 516 are arranged so as to face the bottom surface portion 71. Therefore, when the heated foaming materials 511 and 516 expand, many heated foaming materials 511 and 516 can be expanded from the opening 77 to the outer peripheral surface side of the double glazing 50, and the surface of the sealing portion seal 54 can be expanded. Can be reliably covered.

(6) Since the recess 76 is formed in the bottom surface 71 of the gasket 70, the expanded heated foam materials 511 to 518 can spread from the opening 77 in the recess 76 to cover the sealing portion seal 54. Therefore, even if the area of the opening 77 is small, the heated foaming material 511 to 518 can be expanded in a wider range by providing the recess 76, and the entire surface of the sealing portion seal 54 can be covered more reliably.

[Modification example]
The present invention is not limited to the configuration described in the above embodiments, and modifications within the range in which the object of the present invention can be achieved are included in the present invention.
For example, the heated foaming materials 511 to 518 are not limited to those bonded to the stiles 31 to 34, and may be bonded to the gasket 70 side. That is, the heated foaming materials 511 to 518 may be arranged between the stiles 31 to 34 and the gasket 70.
Further, the number and arrangement positions of the heated foaming materials in each of the frames 31 to 34 are not limited to the above-described embodiment. For example, in the lower stile 32, the heated foaming material may be adhered to the prospective surface portion 321 facing the opening 77 of the bottom surface portion 71. On the contrary, in the upper stiles 31 and the vertical stiles 33 and 34, the heating foaming agent is not arranged on the prospective surface portions 311, 331 and 341, and the outdoor finding pieces 312, 332 and 342 and the indoor finding pieces 313, 333 and 343 are not arranged. A heated foaming material may be adhered to the surface.

The gasket 70 is not limited to the shape and structure disclosed in the above embodiment. For example, a gasket in which the recess 76 is not formed may be used, and at least a plurality of openings 77 may be formed in the bottom surface portion 71.
Further, the shape of the opening 77 is not limited to the square hole, and may be an elliptical shape or the like, and it is sufficient that the sealing portion seal 54 can be covered when the heated foam materials 511 to 518 are expanded by foaming. Further, the plurality of openings 77 of the bottom surface portion 71 of the gasket 70 do not necessarily have to be provided by all the gaskets 70 provided on the four sides (upper, vertical, lower) of the fitting, and only the gasket 70 provided on any one side of the fitting. The opening 77 may be provided in the gasket 70, or the gasket 70 provided on two or three sides of the fitting may be provided with the opening 77.
