The interior of the sash is maintained in a comfortable environment, and the efficiency of cooling and heating can be improved and energy can be saved.

[0004]

However, if the heat insulating sash is heated due to a fire or the like, the heat insulating material may be softened or melted depending on the situation, and particularly the heat insulating member provided on the frame of the shoji is softened. -If it is melted, the indoor member and the outdoor member may be separated from each other and the glass may fall off. For this reason, even if the heat insulating member of the frame is softened and melted, it is required that the glass be reliably held.

It is an object of the present invention to provide a heat insulating sash which can prevent the indoor member and the outdoor member from being separated from each other even if the heat insulating sash is heated by a fire or the like, thereby preventing glass or the like from falling off.

[0006]

The heat insulating sash of the present invention comprises:
A heat insulating sash including an indoor / outdoor member disposed indoors and outdoors, and a heat insulating member connecting the indoor member and the outdoor member, wherein the indoor / outdoor member has projecting sides opposed to each other. And a flame-retardant connecting member that is provided between the protruding portions and sandwiches the protruding portions from inside and outside the room.

In the present invention, since the protruding portions of the indoor member and the outdoor member are sandwiched by the flame-retardant connecting members, even when the heat insulating member is softened or melted by being heated by a fire or the like. The connected state of the indoor member and the outdoor member is maintained by the connecting member. Therefore, there is no fear that the indoor member and the outdoor member are separated from each other, and the glass or the like is securely held, and the glass or the like is prevented from falling off.

At this time, it is preferable that the connecting member is brought into contact with the respective opposing surfaces of the indoor member and the outdoor member. In such a case, since the connecting member is interposed between the indoor and outdoor members in a state of being in close contact with the respective opposing surfaces, when the heat insulating member is softened and melted, the indoor member and the outdoor member do not come close to each other, Glass and the like are maintained in a better state.

Further, in the heat insulating sash of the present invention, the connecting member may be constituted by two members of the first member and the second member, or may be constituted by one member. In the case of a two-member configuration, each member sandwiches the protruding portions of the indoor / outdoor member from the width direction, thereby preventing the indoor / outdoor member from shifting in the width direction. Further, even in the case of a single member, it is connected between the bent portion on the distal end side of each protruding portion provided at intervals in the width direction of the indoor member and the outdoor member, and the base portion of each protruding portion. By disposing the members, the displacement of the indoor and outdoor members in the width direction is similarly prevented.

Can be easily installed.

Further, in the connecting member 20 of the first embodiment,
Although the bent pieces 22A are provided at the upper and lower portions of the second member 22, the bent pieces 22A may be provided at the center in the vertical direction as shown in FIG.

Further, as shown in FIG. 7 and FIG. 8, the expected size (dimension in the indoor and outdoor directions when the second member 22 is finally arranged) constituting the connecting member 20 is changed to the indoor and outdoor member 11. Dimension A2 between Opposing Surfaces 11A, 12A
(A1 = A2), the second member 2
2, the opposing surfaces 11A, 1A are not provided with the bent piece 22A.
The entirety of the second member 22 abutting on 2A is the indoor and outdoor members 11, 1
2 may be prevented from approaching.

In such a case, the second member 2
2 is set to be smaller (B1 <B2) than the expected size B2 between the protruding sides 16 and 17, and a pair of diagonal directions is set. Preferably, the corners are chamfered. That is, by doing so, the second member 22 is previously integrated with the first member 21 and the screw 25 as shown in FIG. 8, and then rotated by 90 degrees from the state where it is finally arranged. In this state, it is inserted between the protruding sides 16 and 17 from the holding portion 14 side, and is disposed on the heat insulating member 13 side. Then, the second member 22 is rotated by rotating the screw 25 in the tightening direction, and the second member 22 is rotated.
It is maintained in a state of being returned 90 degrees in contact with A, and is securely attached by subsequently tightening the screw 23. Therefore, since the first and second members 21 and 22 are inserted in a joined state, the mounting operation can be easily performed similarly to the connecting member 20 shown in FIG.

FIGS. 9A to 9E show a plurality of other modifications of the connecting member 20 of the first embodiment. The connecting member 20 shown in (A) is different from the first embodiment in that the connecting member 20 is composed of a first member 21, a second member 22, and a third member 26, and the second member 22 is simply formed in a plate shape. The third member 26 has a U shape having bent pieces and is interposed between the protruding portions 16 and 17. In the connecting member 20 shown in (B), the first member 21 is provided with two types of U-shaped portions, one of which sandwiches the protruding portions 16 and 17, and the other of which is interposed between the protruding portions 16 and 17. ing. In the connecting member 20 shown in (C), the expected size of the first member 21 is set to be the same as the expected size between the opposing surfaces 11A and 12A of the indoor and outdoor members 11 and 12, and two types of cores as shown in (B). It is possible to prevent the indoor / outdoor members 11, 12 from approaching and separating at the same time without providing the letter-shaped portion. Although each of the connecting members 20 has a different configuration, the above-described effects 1) to 6) can be similarly obtained.

The connecting member 20 shown in (D) has a configuration in which the third member 26 shown in (A) is thinned out. In such a case, the connecting member 20 does not have a portion that comes into contact with the opposing surfaces 11A and 12A of the indoor and outdoor members 11 and 12, and the above-mentioned 2).
Cannot be obtained, but other effects can be obtained similarly.

The connecting member 20 shown in (E) is made of one member, and a bent portion is provided at the end of the central U-shaped portion of the first member 21 shown in (B). And the width of the indoor and outdoor members 11 and 12 in the width direction and the connection member 2
0 prevents itself from coming off to the holding section 14 side. Such a connecting member 20 may be engaged with the protruding portions 16, 17 from the end portions of the frame material or the discontinuous portions 16C, 17C shown in FIG. 3, and the central side U-shaped portion has a spring property. By giving, the part may be elastically deformed (two-dot chain line) and may be engaged with the protruding parts 16, 17 in a one-touch manner.
However, in the case where the one-touch type is engaged, even if the heat insulating member is melted and softened and the indoor and outdoor members 11 and 12 approach, it is necessary to allow the above-mentioned parts to be opposed without being elastically deformed. It is necessary to carefully set the spring force.

FIGS. 10A and 10B show a modification of the second embodiment. In the connecting member 20 shown in (A), a plurality of protrusions 27 are provided on the inner surface of the slit 24, and the pressing force is concentrated by bringing these protrusions 27 into point contact with a protrusion (not shown). In addition, the connecting member 20 is harder to come off in the engaging direction.

In the connecting member 20 shown in (B), the slit 24 is made to be large over a protruding side (not shown).
Even in such a case, the indoor and outdoor members can be prevented from separating. However, in such a connecting member 20, the entire expected dimension is set to the estimated dimension A2 between the facing surfaces of the indoor and outdoor members.
If it is the same as FIG. 8, it is possible to prevent the indoor and outdoor members from approaching.

Further, the heat insulating member constituting the heat insulating sash is not limited to the one into which urethane resin is injected, but is a plate made of synthetic resin, and is disposed between the indoor and outdoor members and caulked. Thereby, these indoor and outdoor members may be connected.

And, as the connecting member according to the present invention,
The material is not limited to metal, and may be any material having flame retardancy such as ceramic.

Further, the heat-insulating sash according to the present invention can be suitably used for a sliding window, a sliding window, an up-and-down window, and especially a heat-insulating sash having a shoji having glass or the like fitted therein.

[0048]

As described above, according to the present invention,
Since each protruding portion of the indoor member and the outdoor member is sandwiched by the flame-retardant connecting member, there is a concern that the indoor member and the outdoor member may be separated from each other even when the heat insulating member is heated and softened or melted by a fire or the like. Therefore, there is an effect that the glass or the like can be securely held to prevent the glass or the like from falling off.
