[0097] In the sliding window 100, the abutting wall parts 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in surface contact with the sealing material 62 and support the sealing material 62. Generally, when the metal frame itself is in contact with the sealing material, if the temperature of the metal frame is lowered by the outside air, the low outside air temperature is transmitted to the indoor side Y2 through the sealing material in contact with the metal frame and the glass panel in contact with the sealing material. In this embodiment, the abutting wall parts 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in contact with the sealing material 62, so that the outside air temperature is not easily transmitted, and the heat insulation can be improved. It is preferable that the metal frames 31A, 33A, 35A, 37A are not in contact with the sealing material 62.

[0098] The sealing materials provided between the glass grooves 32, 34, 36, 38 and the glass panel 50 are the sealing materials 61, 62, so that the durability of the sealing materials can be improved. The abutment walls 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in surface contact with the sealing material 62. Therefore, the gaps between the abutment walls 324, 344, 364 and the sealing material 62 and the gaps between the sealing material 62 and the glass panel 50 can be reduced to improve airtightness.

[0099] The surface 344a of the abutment wall portion 344 of the resin lower frame 33B of the lower frame 33 and the surface 333a facing the outdoor side Y1 of the outer wall portion 333 of the metal lower frame 33A are arranged on approximately the same plane along the width direction X and the vertical direction Z.

It is easy to insert the backup material 57 between the glass grooves 32, 34 and the glass panel 50.

[0100] The support wall 337 of the metal lower frame 33A of the lower frame 33 abuts against the bent piece 348 of the abutment wall 344, supporting the abutment wall 344. The recess 355 of the metal end frame 35A of the end frame 35 and the joint frame 37 abuts against the tip of the bent piece 368 of the abutment wall 364 of the plastic end frame 35B, supporting the abutment wall 364. The metal frames 33A, 35A, 37A support and reinforce the plastic frames 33B, 35B, 37B, improving wind pressure resistance.

[0101] Both ends in the width direction X of the second folded wall portion 339 of the metal lower frame 33A of the lower frame 33 press the second folded wall portion 347 of the resin lower frame 33B toward the outdoor side Y1. Both ends in the width direction X of the second folded wall portion 319 of the metal upper frame 31A of the upper frame 31 press the folded wall portion 327 of the resin upper frame 31B toward the outdoor side Y1. Although the linear expansion coefficients of resin materials and metal materials are different, since the metal frames 31A, 33A and the resin frames 31B, 33B are reliably joined at both ends in the width direction X, the resin frames 31B, 33B are prevented from expanding and contracting in the width direction X relative to the metal frames 31A, 33A, causing the sealing material 62 to break or be damaged, and the durability of the sliding window 100 can be improved.

[0102] Second Embodiment The fitting according to the second embodiment will be described mainly with reference to Fig. 9. In the description of the embodiment shown below, the same members as those described above are given the same reference numerals and the description thereof will be omitted.

A surface 344a of the abutment wall portion 344 abuts against the sealing material 62 and the backup material 57.

[0104] The other frames 31, 35, 37 of the inner screen 3B and the frames 31, 33, 35, 37 of the outer screen 3A are configured in the same manner as the abutment wall portion 344 of the lower frame 33 shown above, so description thereof will be omitted.

[0105] In the sliding window 100, the abutting wall parts 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in surface contact with the sealing material 62 and support the sealing material 62. Generally, when the metal frame itself is in contact with the sealing material, if the temperature of the metal frame is lowered by the outside air, the low outside air temperature is transmitted to the indoor side Y2 through the sealing material in contact with the metal frame and the glass panel in contact with the sealing material. In this embodiment, the abutting wall parts 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in contact with the sealing material 62, so that the outside air temperature is not easily transmitted, and the heat insulation can be improved. It is preferable that the metal frames 31A, 33A, 35A, 37A are not in contact with the sealing material 62.

[0106] The contact wall portions 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B extend further outward in the viewing direction than the backup material 57. This prevents the metal frames 31A, 33A, 35A, 37A from contacting the sealing material 62. Since the linear expansion coefficients of resin materials and metal materials are different, if both the resin frames and the metal frames are in contact with the sealing material, there is a risk that the sealing material will be cut or damaged due to the difference in elongation. In this embodiment, since the metal frames 31A, 33A, 35A, 37A are not in contact with the sealing material 62, cutting or damage to the sealing material 62 is suppressed, and the durability of the sliding window 100 can be improved.

[0107] Third embodiment The fitting according to the third embodiment will be described mainly with reference to Figures 10 to 13. In the description of the embodiment shown below, the same members as those described above are given the same reference numerals and the description thereof will be omitted.

[0108] 10 to 12, in the sliding window 100 according to this embodiment, a glazing channel 63 is provided on the peripheral portion of each of the four sides of the glass panel 50. The glazing channel 63 is provided over substantially the entire length of the peripheral portion of each of the four sides of the glass panel 50.

[0111] The side edge 636 is provided with a pair of inner fins 637, 637 extending toward the corresponding faces 50a, 50b of the glass panel 50. The pair of inner fins 637, 637 are arranged apart in the up-down direction Z. The tip of the inner fin 637 abuts against the faces 50a, 50b of the glass panel 50. The number of inner fins 637 can be set as appropriate.

[0112] An outer fin 638 is provided on the side edge 636, extending opposite the inner fin 637. The outer fin 638 is positioned in the up-down direction between the pair of inner fins 637, 637. The tip of the outer fin 638 on the outdoor side Y1 abuts against the surface of the groove outdoor side panel 332 facing the indoor side Y2.

[0113] A tip fin portion 639 is provided at the tip of the side edge portion 636. The end of the tip fin portion 639 on the outdoor side Y1 on the indoor side Y2 abuts against the surface 50a of the glass panel 50. The end of the tip fin portion 639 on the outdoor side Y1 on the outdoor side abuts against the upper end of the groove outdoor side plate portion 332 of the metal lower frame 33A. The end of the tip fin portion 639 on the indoor side Y1 on the indoor side abuts against the surface 50b of the glass panel 50. The end of the tip fin portion 639 on the indoor side Y2 on the indoor side abuts against the corner portion between the resin inner plate portion 343 and the abutting wall portion 344 of the resin lower frame 33B. The abutting wall portion 344 of the resin lower frame 33B abuts against the upper portion of the side edge portion 636 on the indoor side Y2 in surface contact.

[0114] As shown in Figure 10, in the bottom frame 33 of the outer screen 3A, as in the bottom frame 33 of the inner screen 3B, the abutment wall portion 344 abuts in surface contact with the side edge portion 636 of the glazing channel 63.

[0115] In the upper frame 31 of the outer frame 3A and the inner frame 3B, the glazing channel 63 is arranged with the end face support portion 631 of the glazing channel 63 oriented along the upper end portion 50u of the glass panel 50. The abutment wall portion 324 of the resin upper frame 31B abuts against the side edge portion 636 of the glazing channel 63 in surface contact.

[0116] As shown in Fig. 12, in the door end frame 35 and the joint frame 37 of the outer door 3A and the inner door 3B, the glazing channel 63 is arranged with the end face support portion 631 of the glazing channel 63 oriented along the end portion 50s in the width direction X of the glass panel 50. The abutment wall portion 364 of the plastic door end frame 35B and the joint frame 37B abuts against the side edge portion 636 of the glazing channel 63 in surface contact.

[0117] In the sliding window 100, the abutment wall portions 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in surface contact with the side edge portion 636 of the glazing channel 63 to support the side edge portion 636. Generally, when the metal frame itself is in contact with the glazing channel, when the temperature of the metal frame is lowered by the outside air, the low outside air temperature is transmitted to the indoor side Y2 through the glazing channel that is in contact with the metal frame and the glass panel that is in contact with the glazing channel. In this embodiment, the abutment wall portions 324, 344, 364 of the resin frames 31B, 33B, 35B, 37B are in contact with the glazing channel 63, so that the outside air temperature is not easily transmitted, and the heat insulation can be improved. It is preferable that the metal frames 31A, 33A, 35A, 37A are not in contact with the glazing channel 63.

[0118] The low temperature of the outside air is transmitted to the ends 50d, 50s, and 50u of the glass panel 50 through the glazing channel 63, and the temperature of the ends 50d, 50s, and 50u drops, which may cause condensation on the glass panel 50. In the case of a seal specification in which the sealant 62 is provided as in the first embodiment, the glass panel 50 and the sealant 62 are in surface contact, and the glass panel 50 and the backup material 57 are in surface contact. In contrast, in this embodiment, the glazing channel 63 has convex ribs such as the tip fin portion 639 and the inner fin portion 637 in contact with each other, so that heat transfer is reduced and the temperature transfer to the glass panel 50 is reduced. As a result, condensation can be suppressed and heat insulation can be improved.

The vertical frame 13D has hollow portions S121 to S125, thereby improving the heat insulation property.

[0145] The joint between the end of the upper frame 11D and the lower frame 12D in the width direction X and the vertical frame 13D will be described. FIG. 19 shows an exploded cross section of the joint A1 between the end of the lower frame 12D in the width direction X and the vertical frame 13D. As shown in FIG. 19, a caulking sealer 17 is provided on the joint surface 13a between the metal vertical frame 13A1 and the lower frame 12D. The caulking sealer 17 is also provided between the metal vertical frame 13A1 and the resin lower frame 12B1. The caulking sealer 17 is also provided on the joint surface between the metal vertical frame 13A1 and the upper frame 11D. The caulking sealer 17 is a caulking sealer such as butyl rubber that exerts a water-stopping effect when compressed. The upper frame 11D and the lower frame 12D correspond to the horizontal member in the claims. The vertical frame 13D corresponds to the vertical member in the claims. The width direction X of the upper frame 11D and the lower frame 12D corresponds to the longitudinal direction in the claims. The up-down direction Z of the vertical frame 13D corresponds to the longitudinal direction in the claims. The caulking sealer 17 corresponds to the airtight material in the claims.

[0146] In the fixed window 100D, the abutment wall 137 of the resin frame 11B1, 12B1, 13B1 is in surface contact with the sealant 62 and supports the sealant 62. Generally, when the metal frame itself is in contact with the sealant, if the temperature of the metal frame is lowered by the outside air, the low outside air temperature is transmitted to the indoor side Y2 through the sealant in contact with the metal frame and the glass panel in contact with the sealant. In this embodiment, the abutment wall 137 of the resin frame 11B1, 12B1, 13B1 is in surface contact with the sealant 62, so that the outside air temperature is not easily transmitted, and the heat insulation can be improved. It is preferable that the metal frame 11A1, 12A1, 13A1 is not in contact with the sealant 62.

[0147] Both ends in the width direction X of the lower folded wall portion 128 of the metal lower frame 12A1 of the lower frame 12D press upward against the locked wall portion 139 of the resin lower frame 12B1. Although the linear expansion coefficients of resin materials and metal materials are different, because the metal lower frame 12A1 and the resin lower frame 12B1 are securely joined at both ends in the width direction X, the resin lower frame 12B1 is prevented from expanding and contracting in the width direction X relative to the metal lower frame 12A1, which would cause the sealant 62 to break or be damaged, thereby improving the durability of the fixed window 100D.

[0148] Both ends in the width direction X of the folded wall portion 114 of the metal upper frame 11A1 of the upper frame 11D press the folded wall portion 115 of the resin upper frame 11B1 toward the outdoor side Y1. Although the linear expansion coefficients of resin materials and metal materials are different, because the metal upper frame 11A1 and the resin upper frame 11B1 are securely joined at both ends in the width direction X, the resin upper frame 11B1 is prevented from expanding and contracting in the width direction X relative to the metal upper frame 11A1, which would cause the sealant 62 to break or be damaged, thereby improving the durability of the fixed window 100D.

[0149] Both ends in the vertical direction Z of the folded wall portion 151 of the metal edge 15A1 of the vertical frame 13D press the folded wall portion 142 of the resin vertical frame 13B1 toward the outdoor side Y1. Although the linear expansion coefficients of resin materials and metal materials are different, the metal edge 15A1 and the resin vertical frame 13B1 are securely joined at both ends in the vertical direction Z, so that the resin vertical frame 13B1 is prevented from expanding and contracting in the vertical direction Z relative to the metal edge 15A1, which would cause the sealing material 62 to break or be damaged, thereby improving the durability of the fixed window 100D.

[0150] The lower folded wall portion 128 of the lower metal frame 12A1, the folded wall portion 114 of the upper metal frame 11A1, and the folded wall portion 151 of the metal edge 15A1 are disposed inside in the viewing direction from the bottom of the glass groove 15. This further prevents the sealing material 62 disposed in the glass groove 15 from being cut or damaged.

[0151] A caulking sealer 17 is provided on the joint surface 13a between the metal vertical frame 13A1 and the resin lower frame 12B1 and upper frame 11B1. By sandwiching the caulking sealer 17 between the metal vertical frame 13A1 and the resin lower frame 12B1 and upper frame 11B1, the watertightness of the joint between the metal vertical frame 13A1 and the resin lower frame 12B1 and upper frame 11B1 can be improved.

[0152] Fifth embodiment The fitting according to the fifth embodiment will be described mainly with reference to Figures 20 to 22. In the description of the embodiment shown below, the same members as those described above are given the same reference numerals and the description thereof will be omitted.

[0153] As shown in Figures 20 and 21, in the fixed window 100C according to this embodiment, bead materials 64, 65 are provided on both sides in the indoor-outdoor direction Y of the peripheral portion of the four sides of the glass panel 50. The bead materials 64, 65 are provided over substantially the entire length of the peripheral portion of the four sides of the glass panel 50. The bead material 64 is sandwiched between the surface 50a of the glass panel 50 and the glass groove 15. The bead material 65 is sandwiched between the surface 50b of the glass panel 50 and the glass groove 15. The bead materials 64, 65 are made of, for example, a soft resin material, and polyvinyl chloride resin, chloroprene rubber, etc. can be used.

[0154] As shown in FIG. 22, in the lower frame 12D, the bead material 64 is engaged with the wall portion 124b of the groove outdoor side panel portion 124 of the metal lower frame 12A1. The bead material 64 abuts against the surface 50a of the glass panel 50. A protrusion 651 that protrudes toward the indoor side Y2 is provided on the upper portion of the bead material 65. The protrusion 651 is engaged with the upper end of the abutment wall portion 137. The surface of the bead material 65 facing the indoor side Y2 abuts in surface contact with the abutment wall portion 137 of the resin lower frame 12B1.
