Description

  The present invention relates to a heat insulating sash installed in an opening of a building.

Conventionally, a sash installed in an opening of a building has been required to have a heat insulation property, and the frame body is configured by connecting an indoor side member and an outdoor side member with a heat insulating member, so that heat can be spread indoors and outdoors. Draw-type thermal insulation sashes that prevent transmission are known.
In such a sliding-type heat insulating sash, a cover member made of resin is covered between the outer guide rail of the outdoor member and the inner guide rail of the indoor member, and a shielding member is provided outside the inner guide rail. There has been known a heat insulating sash that improves the heat insulating performance by preventing the outside air or the like from directly hitting the inner guide rail.

JP 2001-55869 A

Normally, the sliding insulation sash is tightly sealed between the shoji and the frame, blocking the outdoor and indoor spaces, but the air to which cold heat is transmitted through the guide rail etc. By convection in the space between the two, cold heat is transmitted to the indoor space, leading to a decrease in heat insulation performance. In particular, between the upper surface of the shoji and the inner peripheral surface of the upper frame, it is necessary to secure a large space for the purpose of securing the standing dimension by Kendon, and the shoji, frame and tight material are used because the shoji is slid. There was also a restriction on the contact between the top and bottom, and the transfer of cold heat due to air convection in a large space between the upper surface of the shoji and the inner peripheral surface of the upper frame was not negligible.
In the heat insulating sash of the above-mentioned patent document 1, by providing a shielding member, it is possible to suppress the presence of outside air directly on the guide rail of the indoor side member and improve the heat insulating performance. The transfer of cold by air convection in the space between the surfaces was not considered.
Therefore, the cold heat transmitted from the outdoor to the outdoor member is transmitted to the air as radiant heat from the indoor surface of the guide rail of the outdoor member, and further transmitted to the indoor by air convection in the space between the shoji and the frame. There was a possibility.

  The present invention has been made in view of the above circumstances, and suppresses convection of air on the indoor side of the guide rail of the upper frame between the upper surface of the shoji and the inner peripheral surface of the upper frame, and from the indoor side surface of the guide rail of the upper frame. An object of the present invention is to provide a heat insulating sash capable of improving the heat insulating performance by preventing the cold heat from being transferred into the room.

  The present invention is characterized in that a protruding portion interposed between the upper surface of the shoji and the inner peripheral surface of the upper frame is provided at a position on the indoor side from the shoji guide rail of the upper frame, and the protruding portion is deformable and recoverable. To do.

  In the space between the upper surface of the shoji and the inner peripheral surface of the upper frame, a protrusion is provided at a position on the indoor side with respect to the guide rail of the upper frame to provide a protrusion between the upper surface of the shoji and the inner peripheral surface of the upper frame. By separating the space between the section and the guide rail and the indoor space, it is possible to suppress convection to the indoor space of air to which cold heat is transmitted by radiant heat from the guide rail or the like. And since the projecting part is provided so that it can be deformed and restored, the projecting part is deformed even if the shoji comes into contact with the projecting part during the construction of the shoji, and when the construction is finished, the projecting part is restored to maintain the predetermined shape. Therefore, the protruding portion can be brought closer to the upper frame or the upper arm of the shoji, and the flow of air from the space to the indoor space can be reliably suppressed.

(Frame structure)
The upper frame 11 is a connection made of a heat insulating material such as a resin connecting the outdoor upper member 111 and the indoor upper member 112, and the outdoor upper member 111 and the indoor upper member 112 formed of a metal material such as aluminum. The member 113 and the resin upper member 114 made of resin are disposed and fixed on the inner periphery of the lower surface of the indoor upper member 112.
An outer guide rail (guide rail) 111a for guiding the outer shoji 3 is suspended from the lower surface of the outdoor upper member 111 which is closer to the outdoor side. An inner guide rail (guide rail) 112a for guiding 2 is suspended.

The resin upper member 114 includes an outdoor wall portion 114a that covers the indoor surface of the inner guide rail 112a of the indoor upper member 112, an upper wall portion 114b that covers the lower surface of the indoor upper member 112, and an indoor side end of the upper wall portion 114b. It consists of an indoor wall portion 114c that hangs downward and a forehead portion 114d that extends from the lower end of the indoor wall portion 114c to the indoor side.

The inter-rail upper cover 51 is configured as a substantially flat plate-like long member having substantially half the length of the upper frame 11, and at least a windshield plate installed above the summing portion of the upper frame 11. d is disposed between the left vertical frame 14 and the inside and outside of the outer shoji 2 and 3 to prevent cold from being transmitted to the room from the lower surface of the outdoor upper member 111 exposed to the room. .

  Further, the bottom surface of the upper rail-to-rail cover 51 on the indoor side of the outer guide rail 111a and the lower surface of the upper wall portion 114b of the upper resin member 114 on the indoor side of the inner guide rail 112a are finned with a soft material such as soft resin. The protrusions 71 and 72 are suspended so as to be inclined toward the room as they go downward, and are provided so as to be close to or in contact with the outer surfaces of the inner and outer nails 3 and 2.

  Since the protrusions 71 and 72 are formed of a soft material so that they can be deformed and restored, when the inner and outer shojis 2 and 3 are stood up with Kendon, the fin-like protrusions 71 and 72 are easily deformed. The standing work can be performed smoothly. Further, after construction, the lower end of the projecting portions 71, 72 can be restored to the original shape, and can be brought close to or in contact with the upper surface of the outer shoji 2, 3, so the inner peripheral surface of the upper frame 11 and the inner shoji The projecting portions 71 and 72 can block at least a part of the interval after the completion of the construction while securing a sufficient space to enable the shoji to be installed between the top surfaces of the second and third surfaces.

  Thereby, the space between the inner peripheral surface of the upper frame 11 on the indoor side of the outer and inner guide rails 111a and 112a and the upper surface of the inner and outer nails 3 and 2 is separated from the indoor space, and the outer and inner guide rails 111a and 112a are separated. The convection which the air to which cold heat was transmitted from the indoor side surface of this through the space flows into the room is suppressed.

  Furthermore, since the protrusions 71 and 72 are suspended while being inclined so as to become the indoor side as going downward, the deformation during the construction of the shoji is uniformly performed over the entire length in the longitudinal direction, and twisting or the like is performed in the middle. Can be prevented, and a good proximity or contact state can be maintained during restoration.

As Example 1, a heat insulating sash provided with a fin-like protrusion 71 on the lower surface of the inter-rail upper cover 51, and as Example 2, it further protrudes into the resin upper member 114, the resin lower member 124, and the resin right member 132, respectively. The heat insulating sash provided with the portions 81, 82, and 83 was used, and the fin-like protruding portion 71 and the protruding portions 81, 82, and 83 were not provided as a comparative example.
Table 1 shows the heat transmissivity of Examples 1 and 2 and Comparative Example of the present invention.
The heat transmissivity is used as one of the criteria for evaluating the heat insulation performance of the sash and the like, and the amount of heat passing through 1 m ² per hour when the temperature difference between the inside and outside of the sash and the like is 1 degree. Expressed in watts, the smaller the value, the better the heat insulation.
In the table, LE3-G16-3 is Low-E 3 mm glass + intermediate gas layer 16 mm + float transparent 3 mm glass double layer glass, and LE3-A16-3 is Low-E 3 mm glass + intermediate air layer 16 Multi-layer glass of millimeter + float transparent 3 mm glass, 3-G16-3, indicates a double-layer glass of float transparent 3 mm glass + medium air layer 10 mm + float transparent 3 mm glass.

  From Table 1, in any sash using any multilayer glass, a comparative example in which no protrusion is provided on any side of the window frame by providing a fin-like protrusion 71 on the lower surface of the upper cover 51 between the rails. On the other hand, the heat transmissibility is improved by 0.04 to 0.05 points, and furthermore, by providing the protrusions 81, 82 and 83 on the resin upper member 114, the resin lower member 124 and the resin right member 132, respectively, It is improved by 0.04 to 0.05 points, and it can be seen that the heat insulation of the sash is improved.

As described above, by interposing a protrusion that can be deformed and restored in the space between the inner peripheral surface of the upper frame 11 on the indoor side of the outer and inner guide rails 111a and 112a and the upper surface of the inner and outer impellers 2 and 3, During the construction work of the external shoji 2 and 3 by Kendon, it easily deforms and does not get in the way, and when the construction work is finished, it is restored to its original shape, and the inner peripheral surface of the upper frame 11 and the inside and outside Since it can be brought close to or in contact with either of the upper surfaces of the shoji 2 and 3, a sufficient space is provided to allow the shoji to be built between the inner peripheral surface of the upper frame 11 and the upper surface of the outer shoji 2 and 3. The fin pieces (protruding portions) 71 and 72 can close at least a part of the interval after the completion of the erection, and the upper frame 11 has an inner peripheral surface and an inner surface of the outer shoji 2,3. Air convection between them can be suppressed.
And, by projecting the projecting portion at an angle, the deformation during the construction of the shoji is uniformly performed over the entire length in the longitudinal direction, and it is possible to prevent twisting and the like from occurring in the middle, and good proximity when restoring Alternatively, the contact state can be maintained.
The protrusion may be provided on the indoor side of either the inner guide rail or the outer guide rail, but it is provided on the indoor side of both the inner guide rail and the outer guide rail. It is preferable to suppress air convection over the entire length of the upper frame 11 by making them approach.
Further, the resin upper member 114, the protrusions 81 and 82 provided at the inner peripheral end of the resin upper member 114, and the protrusions 83 and 84 provided at the inner peripheral end of the resin right member 55 and the resin left member 56. , And in cooperation with the protrusions 71 and 72 provided on the rail upper cover 51 and the resin upper member 114, it is possible to prevent the transfer of cold heat due to air convection over the four circumferences of the heat insulating sash. A heat insulating structure can be obtained.

  In addition, it is preferable that the projecting portion is in contact with either the upper frame or the upper collar, or is about 2 mm or less, but if close enough to be about 10 mm or less, convection can be suppressed to some extent. Insulation performance can be improved.
