  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 2 and 3 show an embodiment of a sash according to the present invention, which shows an example applied to a sliding sash for a house. FIG. 1A is an enlarged cross-sectional view of the lower frame 15 of the sash. FIG. This sash is opened and closed by moving the sash frame 10 attached to the housing opening, the outer shoji 11 and the inner shoji 12 accommodated in the sash frame 10 so as to be freely opened and closed, and moved to the outside of the outer door 11 in the left-right direction. The screen door 13 to be used.

The sash frame 10 is configured by a four-sided frame of an upper frame 14, a lower frame 15, and left and right collar frames 16, 16. As shown in FIG. 1 (a), the lower frame 15 includes an outdoor frame member 1 and an indoor frame member 2 made of an extruded shape of an aluminum alloy, and two heat insulating materials 3a and 3b on the inner peripheral side and the outer peripheral side. It becomes the heat insulation sash frame connected with.
The heat insulating materials 3a and 3b are arranged so as to be displaced in the indoor and outdoor directions so that the inner heat insulating material 3a is located on the outdoor side of the outer heat insulating material 3b. The amount of both the heat insulating materials 3a, 3b displaced in the indoor / outdoor direction is about half of the size of the heat insulating materials 3a, 3b in the indoor / outdoor direction. As the heat insulating materials 3a and 3b, non-shrinkable hard resin materials such as phenol resin or polyester resin reinforced with glass fibers are used. The end portions on the outdoor side and the indoor side of the heat insulating materials 3a and 3b are swelled in a substantially triangular cross section.

The outdoor frame member 1 has an outer rail 17 that guides the shoji 11 projecting toward the inner peripheral side, and a housing mounting fin 18 that is attached to the housing at the indoor side end portion and projecting toward the outer peripheral side. . On the indoor side surface of the outdoor frame 1, connecting grooves 4 a and 4 b in which the outdoor ends of the heat insulating materials 3 a and 3 b are fitted on the inner peripheral side and the outer peripheral side are shifted in the indoor and outdoor directions. And has an inclined portion 19a between the connecting grooves 4a and 4b.
The indoor side frame member 2 has an inner rail 20 that guides the inner shroud 12 at the outer end of the indoor side projecting toward the inner peripheral side, and has a frame attachment fin 21 for attaching to the outer peripheral side of the indoor side surface on the indoor side. Projecting. On the outdoor side surface of the indoor side frame member 2, as in the outdoor side frame member 1, there are connecting grooves 4 c and 4 d in which the indoor side ends of the heat insulating materials 3 a and 3 b are fitted on the inner peripheral side and the outer peripheral side. The positions are shifted outward and are formed in steps, and an inclined portion 19b is provided between the connecting grooves 4c and 4d.
Each of the connecting grooves 4a, 4b, 4c, 4d has a dovetail shape in which the groove width gradually increases toward the bottom of the groove, and the inlet side of the connecting grooves 4a, 4b, 4c, 4d is slightly expanded. After inserting the end portions of the heat insulating materials 3a and 3b into the connecting grooves 4a, 4b, 4c and 4d, press the caulking rollers 22a and 22b from the inner peripheral side and the outer peripheral side of the lower frame 15 as shown in FIG. Then, by crimping the opening edges 5a, 5d, 5e, 5h of the inner and outer peripheral connecting grooves 4a, 4b, 4c, 4d, the heat insulating material 3a, in the connecting grooves 4a, 4b, 4c, 4d, The end portion of 3b is firmly fitted and held.

  When the heat insulating materials 3a and 3b on the inner peripheral side and the outer peripheral side are arranged at the same position in the indoor / outdoor direction, between the frame mounting fin 18 of the outdoor frame member 1 and the inner rail 20 of the indoor frame member 2. However, the sash lower frame 15 is arranged so that the heat insulating material 3a on the inner peripheral side is placed on the outdoor side of the heat insulating material 3b on the outer peripheral side. By disposing them, the distance between the frame mounting fin 18 of the outdoor frame member 1 and the inner rail 20 of the indoor frame member 2 can be reduced, and the outer shape of the lower frame 15 is accordingly shown in FIG. It becomes possible to make it the same as the lower frames 91 and 92 of other conventional sashes shown in b) and (c). 1B shows an integrally formed lower frame 91 that does not include a heat insulating material. FIG. 1C shows a case where a heat insulating material 95 is cast between the outdoor side frame material 93 and the indoor side frame material 94. The lower frame 92 is connected. In this way, by making the outer shape of the lower frame 15 the same as the lower frames 91 and 92 of other existing sashes, the external shoji 11 and the inner shoji 12 can be shared with other sashes and compatible with other sashes. Have sex. Compared with the integrally formed lower frame 91 shown in FIG. 1B, the sash lower frame 15 is provided with heat insulating materials 3 a and 3 b between the outdoor frame material 1 and the indoor frame material 2, so that the heat insulating property is reduced. There are advantages such as improvement, prevention of dew condensation on the indoor side, and reduction of heating and cooling costs. In the type in which the heat insulating material 95 as shown in FIG. 1C is cast, urethane resin is used as the heat insulating material 95, and since this heat insulating material 95 has low hardness and is weak against heat, the heat insulating material 95 is used in a fire. However, in this sash lower frame 15, phenol resin or polyester resin is used as the heat insulating materials 3 a and 3 b, but the lower frame is deformed and the combustible gas is easily generated from the molten heat insulating material 95. Because non-shrinkable hard resin material reinforced with glass fiber is used, it is not easily deformed by the heat of the fire, and since there is little combustible gas generated from the heat insulating materials 3a and 3b at the time of fire, the fireproof performance of the sash It can be improved.

  5 and 6 show an example of an apparatus in which the heat insulating materials 3a and 3b are caulked to the connecting grooves 4a, 4b, 4c and 4d of the outdoor frame material 1 and the indoor frame material 2 and the lower frame 15 is integrated. ing. This apparatus rotates by sandwiching the lower frame 15 that is horizontally oriented so that the outdoor side surface is on the top and bottom, and moves the lower frame 15 in the longitudinal direction, and the inner periphery of the lower frame 15.

It has an auxiliary roller 25 that is spaced apart above the caulking roller 22a and rotates with the caulking roller 22a while abutting against the horizontal portion of the outer peripheral side surface of the outdoor frame member 1. Since the positions of the heat insulating materials 3a and 3b on the inner peripheral side and the outer peripheral side are shifted in the indoor / outdoor direction, the left and right caulking rollers 22a and 22b are vertically offset.

  Since the left and right caulking rollers 22a and 22b are offset vertically in this way, the lower frame 15 is applied with the pressing forces F1 and F2 being shifted vertically from the caulking rollers 22a and 22b, and there is no auxiliary roller 25. Although the lower frame 15 tends to rotate counterclockwise (see FIG. 8), in this apparatus, the auxiliary roller 25 comes into contact with the outdoor frame material 1 at a position away from the caulking roller 22a. Can be prevented from rotating and twisting. By integrating the auxiliary roller 25 with the caulking roller 22a, the structure of the apparatus can be simplified and the effect of preventing the lower frame 15 from rotating and twisting can be enhanced.

  FIGS. 7A and 7B illustrate another example of the arrangement of the auxiliary roller 25. In FIG. 7A, the upper roller 23 also serves as the auxiliary roller 25, and the lower frame is brought into contact with the wall from which the screen door rail 40 of the outdoor frame 1 projects by the side surface of the upper roller 23. 15 rotations are restricted. In FIG. 7B, the auxiliary roller 25 is brought into contact with the outdoor side surface of the outer rail 17 of the outdoor frame member 1 to restrict the rotation of the lower frame 15. 7C, the auxiliary roller 25 is provided integrally with the right caulking roller 22b, and the auxiliary roller 25 is brought into contact with the inner peripheral side surface of the indoor side frame member 2 to restrict the rotation of the lower frame 15. ing. FIG. 7-2 (d) shows that the lower roller 24 also serves as the auxiliary roller 25, and the lower roller 24 comes into contact with the corners of the indoor side wall of the indoor side frame member 2 and the housing mounting fins 21, thereby lowering the lower frame. 15 rotations are restricted. In FIG. 7-2 (e), the auxiliary roller 25 is provided integrally with the left caulking roller 22a, and the auxiliary roller 25 is brought into contact with the protruding piece 26 of the outdoor frame member 1 to restrict the rotation of the lower frame 15. ing. As described above, the auxiliary roller 25 may be provided anywhere as long as the rotation of the lower frame 15 can be restricted. A plurality of auxiliary rollers 25 may be provided.

In this sash lower frame 15, in order to increase the fitting strength of the end portions of the heat insulating materials 3a, 3b to the connecting grooves 4a, 4b, 4c, 4d of the outdoor side frame material 1 and the indoor side frame material 2, the caulking rollers 22a, Prior to caulking at 22b, knurling 27 (gagged) is applied to predetermined opening edges of the connecting grooves 4a, 4b, 4c and 4d.
