[0011] As shown in Figure 1, the upper frame 11 of the vertical sliding window in this embodiment comprises an upper frame material 111 made of a metal material such as an aluminum alloy, and a resin upper member 110 attached to the indoor side inner circumference of the upper frame material 111. The resin upper member 110 has an outer peripheral member 112 attached to the inner circumference of the upper frame member 111, and an inner peripheral member 113 attached to the inner circumference of the outer peripheral member 112.

[0012] The upper frame material 111 has an airtight seal mounting groove 111g on its exterior side, and an exterior airtight seal s12 that abuts against the upper frame 21 of the sliding door is attached to it. The upper frame material 111 has an opening / closing mechanism 4, such as a link mechanism that supports the sliding door, attached to its inner surface.

[0013] The resin upper member 110 attached to the upper frame member 111 has an airtight seal mounting groove 112g on the outdoor side surface of the outer peripheral member 112, and the indoor airtight seal s11 that abuts against the upper frame 21 of the sliding door is attached to the airtight seal mounting groove 112g. The resin upper member 110 is provided with a projection 113d that extends outward from the outdoor end of the inner circumferential member 113 and approaches the shoji screen without coming into contact with it.

[0014] The upper frame 21 of the sliding window sash in this embodiment is made of a metal material such as an aluminum alloy and has a panel holding portion 21a that holds the panel 25 and an outer peripheral piece 21b that extends outward from the outdoor side of the panel holding portion 21a. The upper frame 21 is supported by the upper frame 11 via an opening and closing mechanism 4 attached to the inner circumferential surface of the upper frame material 111. When the sliding door is closed, the indoor side wall portion of the panel holding portion 21a abuts against the indoor side airtight material s11 of the upper frame 11, and the outer periphery piece 21b abuts against the outdoor side airtight material s12 of the upper frame 11, thereby forming airtight lines.

[0015] As shown in Figure 1, the lower frame 12 of the vertical sliding window in this embodiment comprises a lower frame material 121 made of a metal material such as an aluminum alloy, and a resin lower member 120 attached to the indoor inner circumference of the lower frame material 121. The resin lower member 120 has an outer peripheral member 122 attached to the inner circumference of the lower frame member 121, and an inner peripheral member 123 attached to the inner circumference of the outer peripheral member 122.

[0016] The lower frame material 121 has an opening / closing mechanism 4, such as a link mechanism that supports the sliding door, attached to its inner surface. The resin lower member 120 attached to the lower frame member 121 has an airtight seal mounting groove 122g on the outdoor side surface of the outer peripheral member 122, and an airtight seal s21 that abuts against the lower frame 22 of the sliding door is attached to it. The resin lower member 120 is provided with a projection 123d that extends outward from the outdoor end of the inner circumferential member 123 and approaches the sash without abutting it.

[0017] The lower frame 22 of the sliding window sash in this embodiment is made of a metal material such as an aluminum alloy, has the same structure as the upper frame 21, and includes a panel holding portion 22a that holds the panel 25, and an outer peripheral piece 22b that extends outward from the outdoor side of the panel holding portion 22a.

[0018] The lower frame 22 is supported via an opening and closing mechanism 4 attached to the inner circumferential surface of the lower frame material 121. When the sliding door is closed, the indoor side wall portion of the panel holding portion 22a comes into contact with the airtight material s21 of the lower frame 12, forming an airtight line.

[0019] As shown in Figure 2, the vertical frame 13 of the vertical sliding window in this embodiment comprises a vertical frame member 131 made of a metal material such as an aluminum alloy, and a resin vertical member 130 attached to the inner circumference of the vertical frame member 131 on the indoor side. The resin vertical member 130 has an outer peripheral member 132 attached to the inner circumference of the vertical frame member 131, and an inner peripheral member 133 attached to the inner circumference of the outer peripheral member 132. Furthermore, the left and right vertical frames 13, 13 have a similar configuration, and the outer peripheral member 132 and inner peripheral member 133 that constitute the resin vertical member 130 have the same cross-sectional shape as the outer peripheral member 112 and inner peripheral member 113 that constitute the resin upper member 110.

[0020] The resin vertical member 130 attached to the vertical frame member 131 has an airtight seal mounting groove 132g on the outdoor side surface of the outer peripheral member 132, and an airtight seal s31 that abuts against the vertical frame 23 of the sliding door is attached to it.

[0021] The resin vertical member 130 is provided with a projection 133d that extends outward from the outdoor end of the inner circumferential member 133 and approaches the sash without abutting it.

[0022] The vertical frame 23 of the sliding window sash in this embodiment has the same configuration as the upper frame 21 and lower frame 22, is made of a metal material such as an aluminum alloy, and has a panel holding portion 23a that holds the panel 25, and an outer peripheral piece 23b that extends outward from the outdoor side of the panel holding portion 23a.

[0023] When the sliding door is closed, the vertical frame 23 has an indoor-side wall portion of the panel holding portion 23a that abuts against the airtight material s31 of the vertical frame 13, forming an indoor-side airtight line, and the outer peripheral piece 23b is close to the protruding piece 131d that extends inward from the outdoor-side inner peripheral surface of the vertical frame 13, forming an outdoor-side airtight line.

[0024] As described above, in this embodiment, the vertical sliding window is formed by attaching resin members (resin upper member 110, resin lower member 120, and resin vertical member 130) to the interior inner circumference of the metal frame material (upper frame material 111, lower frame material 121, and vertical frame material 131). The resin members constitute the interior visible wall portion that hides the sash frame, thus forming a concealed frame.

[0025] Furthermore, in this embodiment, the vertical sliding window improves airtightness and heat insulation by arranging airtight materials s11, s21, and s31 that abut against the frame of the sash at an intermediate position in the visible direction on the outdoor side surface of the resin member forming the concealed frame, thereby forming an airtight line that extends along all four sides.

[0026] Here, the airtight seals s11, s21, and s31, which are positioned at the midpoint in the visible direction on the outdoor side surface of the resin members of the upper frame 11, lower frame 12, and left and right vertical frames 13, 13, are difficult to make continuous over all four sides because discontinuities occur at the corners of the frame when using a simple notched frame.

[0027] In this embodiment, the vertical sliding window connects the airtight seals s11, s21, and s31, which are positioned at an intermediate position in the visible direction on the exterior side of the concealed frame, at the corners of the frame. To achieve this, the resin member is formed from two members, an inner circumferential member and an outer circumferential member, making it possible to connect the airtight seals at the corners of the frame with minimal processing. The following describes the framework structure at the corners (upper right and lower right) of the frame material.

[0028] -Composition of the upper corner- (Cross-sectional structure of upper frame 11 and vertical frame 13) In this embodiment, the vertical sliding window consists of a vertical frame (one member) 13 and an upper frame (the other member) 11, with the vertical frame being superior to the upper frame. That is, the left and right end faces of the upper frame 11 abut against the inner circumference of the upper end portion of the vertical frame 13 to form the frame.

[0029] As shown in Figures 3(a) and 3(b), the upper frame member 111 constituting the upper frame 11 includes an upper frame member main body portion 111a having a hollow section, an indoor-side facing wall portion 111b continuous with the indoor side of the upper frame member main body portion 111a, an indoor-side facing wall portion 111c extending inward (downward) from the indoor-side end of the indoor-side facing wall portion 111b, an outdoor-side facing wall portion 111d extending inward (downward) from the outdoor-side end of the indoor-side facing wall portion 111b, and a mounting piece 111h extending outward from the upper frame member main body portion 111a.

[0030] The upper frame member 111 is provided with engaging portions 111e and 111f at the inner circumference end of the indoor side visible wall portion 111c and the inner circumference end of the outdoor side visible wall portion 111d, respectively. The upper frame member 111 has an airtight seal mounting groove 111g on the outdoor side surface of the upper frame member body portion 111a.

[0031] As shown in Figures 3(a) and 3(c), the outer peripheral member 112 constituting the resin upper member 110 of the upper frame 11 has a recessed wall portion 112a, an indoor mounting wall portion 112b extending outward from the indoor side of the recessed wall portion 112a, an outdoor mounting wall portion 112c extending outward from the outdoor outer peripheral of the recessed wall portion 112a, an indoor visible wall portion 112d extending inward from the indoor side of the recessed wall portion 112a, an outdoor visible wall portion 112e extending inward from the outdoor side of the recessed wall portion 112a, and an angle portion 112f in which the recessed wall portion 112a extends further inward than the indoor visible wall portion 112d.

[0032] The outer peripheral member 112 has engaging portions 112h and 112i provided on the outer peripheral portions (upper ends) of the indoor mounting wall portion 112b and the outdoor mounting wall portion 112c, respectively, and engaged portions 112j and 112k provided on the outdoor side surface of the indoor visible wall portion 112d and the indoor side surface of the outdoor visible wall portion 112e, respectively.

[0033] The outer peripheral member 112 is attached to the upper frame member 111 by engaging the engaging portions 112h and 112i of the indoor mounting wall portion 112b and the outdoor mounting wall portion 112c with the engaging portions 111e and 111f provided on the indoor visible wall portion 111c and the outdoor visible wall portion 111d of the upper frame member 111.

[0038] The vertical frame member 131 is provided with engaging portions 131e and 131f at the inner circumference end of the indoor-facing wall portion 131b and the inner circumference end of the outdoor-facing wall portion 131c, respectively.

[0039] As shown in Figures 4(a) and 4(c), the outer peripheral member 132 constituting the resin vertical member 130 of the vertical frame 13 has a recessed wall portion 132a, an indoor mounting wall portion 132b extending outward from the indoor side of the recessed wall portion 132a, an outdoor mounting wall portion 132c extending outward from the outdoor side of the recessed wall portion 132a, an indoor visible wall portion 132d extending inward from the indoor side of the recessed wall portion 132a, an outdoor visible wall portion 132e extending inward from the outdoor side of the recessed wall portion 132a, and an angle portion 132f in which the recessed wall portion 132a extends further inward than the indoor visible wall portion 132d.

[0040] The outer peripheral member 132 is provided with engaging portions 132h and 132i at the outer peripheral ends of the indoor mounting wall portion 132b and the outdoor mounting wall portion 132c, respectively, and engaged portions 132j ​​and 132k are provided on the outdoor side surface of the indoor visible wall portion 132d and the indoor side surface of the outdoor visible wall portion 132e, respectively.

[0041] The outer peripheral member 132 is attached to the vertical frame member 131 by engaging the engaging portions 132h and 132i of the indoor mounting wall portion 132b and the outdoor mounting wall portion 132c with the engaging portions 131e and 131f provided on the indoor visible wall portion 131b and the outdoor visible wall portion 131c of the vertical frame member 131.

[0042] The outer peripheral member 132 has an airtight seal mounting groove 132g along its inner peripheral edge on the outdoor surface of the outdoor facing wall portion 132e, and the indoor airtight seal s31 that abuts against the vertical frame 23 of the sliding door is attached to the airtight seal mounting groove 132g.

[0043] The inner circumferential member 133 constituting the resin vertical member 130 of the vertical frame 13 has the same configuration as the inner circumferential member 113 of the upper frame 11, and as shown in Figures 4(a) and 4(d), it has a recessed wall portion 133a, an indoor visible wall portion 133b extending outward from the indoor end of the recessed wall portion 133a, and an outdoor visible wall portion 133c extending outward from the outdoor end of the recessed wall portion 133a, and a projection portion 133d extending outward from the outdoor end of the recessed wall portion 133a is provided.

[0044] The inner circumferential member 133 has engaging portions 133e and 133f at the outer circumferential ends of the indoor side visible wall portion 133b and the outdoor side visible wall portion 133c, respectively. The engaging portions 133e and 133f are engaged with the engaged portions 132j ​​and 132k of the indoor side visible wall portion 132d and the outdoor side visible wall portion 132e of the outer circumferential member 132, respectively, and the inner circumferential member 133 is attached to the outer circumferential member 132.

[0045] (Connection between upper frame 11 and vertical frame 13) When connecting the upper frame 11 and the vertical frame 13, the vertical frame member 131 of the vertical frame 13 has its recessed wall portion 131a, the indoor-side visible wall portion 131b, the outdoor-side visible wall portion 131c, and the upper portion of the protruding piece 131d appropriately cut out to prevent interference with the upper frame member 111 of the upper frame 11. Furthermore, the outer peripheral member 132 of the vertical frame 13 has the angle portion 132f, the recessed wall portion 132a, the outdoor mounting wall portion 132c, the indoor visible wall portion 132d, and the upper portion of the outdoor visible wall portion 132e appropriately cut out.

[0046] On the other hand, the upper frame material 111 and the outer peripheral member 112 of the upper frame 11 are cut vertically at both ends.

[0047] As shown in Figures 6 and 7, the upper part of the vertical frame member 131a of the recessed wall portion 131a is cut out from the upper end of the vertical frame member 131 by a length of dimension d. The dimension d of the cutout in the recessed wall portion 131a is, for example, approximately equal to the height dimension d' of the mounting piece 111h of the upper frame member 111, so that when the end face of the upper frame member 111 is brought into contact with the upper inner surface of the vertical frame member 131, the mounting piece 131h of the vertical frame member 131 and the mounting piece 111h of the upper frame member 111 come into contact with or be close to the outer periphery of the upper frame member body portion 111a and the recessed wall portion 131a.

[0048] The vertical frame member 131 has the upper part of the interior facing wall portion 131b cut out by a length of dimension a from the upper end of the recessed wall portion 131a, the upper part of the exterior facing wall portion 131c cut out by a length of dimension b from the upper end of the recessed wall portion 131a, and the upper part of the protruding piece 131d cut out by a length of dimension c from the upper end of the recessed wall portion 131a.

[0049] The dimension a of the cutout in the interior facing wall portion 131b is approximately equal to the length dimension a' from the outer peripheral surface of the upper frame member body portion 111a of the upper frame member 111 to the inner peripheral tip of the interior facing wall portion 111c. This dimension ensures that when the end face of the upper frame member 111 is brought into contact with the upper inner peripheral surface of the vertical frame member 131, the interior facing wall portion 131b of the vertical frame member 131 and the interior facing wall portion 111c of the upper frame member 111 are continuous without interference.

[0050] Similarly, the dimension b of the cutout at the upper end of the exterior facing wall portion 131c is approximately equal to the length dimension b' from the outer peripheral surface of the upper frame member body portion 111a of the upper frame member 111 to the inner peripheral tip of the exterior facing wall portion 111d. This dimension ensures that when the end face of the upper frame member 111 is brought into contact with the upper inner peripheral surface of the vertical frame member 131, the exterior facing wall portion 131c of the vertical frame member 131 and the exterior facing wall portion 111d of the upper frame member 111 are continuous without interference.

[0051] Similarly, the dimension c of the cutout at the upper end of the protruding piece 131d is approximately equal to the dimension c' from the outer circumferential surface to the inner circumferential surface of the upper frame member body portion 111a of the upper frame member 111, and is such that the protruding piece 131d of the vertical frame member 131 does not interfere with the upper frame member body portion 111a of the vertical frame member 131 when the end face of the upper frame member 111 is brought into contact with the inner circumferential surface of the vertical frame member 131.

[0052] As shown in Figures 6 and 7, the outer peripheral member 132 of the vertical frame 13 has the upper part of the angle portion 132f cut out by a length of dimension e from the upper end, and the upper outdoor portion of the recessed wall portion 132a and the outdoor mounting wall portion 132c are cut out by a length of dimension f from the upper end.

[0053] The upper portion of the angle portion 132f of the outer peripheral member 132 of the vertical frame 13, and the upper outdoor portion of the visible wall portion 132a and the outdoor mounting wall portion 132c are cut out. This allows the upper end of the outer peripheral member 132 of the vertical frame 13 to enter between the indoor visible wall portion 111c and the outdoor visible wall portion 111d of the upper frame material 111, enabling the end face of the outer peripheral member 112 of the upper frame 11 to contact and fix the inner peripheral surface of the outer peripheral member 132 of the vertical frame 13.

[0054] The outer perimeter member 132 has a cutout of length g from the upper end of the angle portion 132f at the upper part of the indoor side visible wall portion 132d, and a cutout of length h from the upper end of the outdoor side visible wall portion 132e at the upper part of the interior wall portion 132a at the outdoor side.

[0055] The cutout dimension g of the interior facing wall portion 132d is approximately equal to the dimension g' from the outer circumference of the angle portion 112f of the outer peripheral member 112 of the upper frame 11 to the lower end of the interior facing wall portion 112d. This dimension ensures that when the end face of the outer peripheral member 112 of the upper frame material 111 is brought into contact with the upper inner surface of the outer peripheral member 132 of the vertical frame 13, the interior facing wall portion 132d of the outer peripheral member 132 of the vertical frame 13 and the interior facing wall portion 112d of the outer peripheral member 112 of the upper frame 11 are continuous without interference.

[0056] Similarly, the cutout dimension h of the exterior facing wall portion 132e is approximately equal to the dimension h' of the exterior facing wall portion 112e from the outer periphery side of the recessed wall portion 112a of the outer peripheral member 112 of the upper frame 11, and is such that when the end face of the outer peripheral member 112 of the upper frame material 111 is brought into contact with the upper inner surface of the outer peripheral member 132 of the vertical frame 13, the exterior facing wall portion 132e of the outer peripheral member 132 of the vertical frame 13 and the exterior facing wall portion 112e of the outer peripheral member 112 of the upper frame 11 are continuous without interference.

[0057] When connecting the upper frame 11 and the vertical frame 13, as shown in Figures 8 and 9, first, the outer peripheral member 132 is attached to the indoor side inner circumference of the vertical frame member 131 of the vertical frame 13, and the outer peripheral member 112 is attached to the indoor side inner circumference of the upper frame member 111 of the upper frame 11.

[0058] The outer peripheral member 132 of the vertical frame 13 is attached to the vertical frame member 131 with the upper end of the indoor mounting wall portion 132b aligned with the upper end of the indoor visible wall portion 131b of the vertical frame member 131, and the upper end of the outdoor mounting wall portion 132c aligned with the upper end of the outdoor visible wall portion 131c.

[0059] On the other hand, the outer peripheral member 112 of the upper frame 11 is attached so as to be located on the inner circumference side by a length of dimension i from the end of the upper frame material 111. In other words, the outer peripheral member 112 of the upper frame 11 is formed to be twice as short as the upper frame material 111 by a dimension i.

[0060] The dimension i between the end of the outer peripheral member 112 of the upper frame 11 and the end of the upper frame material 111 is approximately equal to the dimension i' from the inner surface of the recessed wall portion 131a of the vertical frame material 131 of the vertical frame 13 to the inner surface of the recessed wall portion 132a of the outer peripheral member 132 of the vertical frame 13. This is set so that when the end face of the upper frame material 111 abuts against the inner surface of the recessed wall portion 131a of the vertical frame material 131, the end face of the outer peripheral member 112 of the upper frame 11 abuts against the inner surface of the recessed wall portion 132a of the outer peripheral member 132 of the vertical frame 13.

[0061] The outer periphery member 112 is attached to the outer periphery member 111, and the end face of the upper frame member 111 is attached to the inner periphery member 132 of the vertical frame member 131, and the two are connected by fixing means such as screws, as shown in Figures 10 and 11.

[0062] At this time, the upper end of the outdoor-facing visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13 is cut out by a length of dimension h (the cut-out portion is called the "notch h"), so the outer peripheral member 112 of the upper frame 11 is connected by its end face abutting against the visible wall portion 132a of the notch h of the outer peripheral member 132 of the vertical frame 13.

[0063] As a result, the end of the airtight material mounting groove 132g provided on the outdoor surface of the outdoor visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13 abuts against the airtight material mounting groove 112g provided on the outdoor surface of the outdoor visible wall portion 112e of the outer peripheral member 112 of the upper frame 11 from the inner side, thereby enabling the airtight material s31 of the vertical frame 13 and the airtight material s11 of the upper frame 11 to be continuous.

[0064] Subsequently, the inner circumferential member 113, which is cut perpendicularly from the inner side, is attached to the outer circumferential member 112 of the upper frame 11, and the inner circumferential member 133 of the vertical frame 13, which is cut perpendicularly from the inner side, is attached to the outer circumferential member 132 of the vertical frame 13, thereby completing the framing of the vertical frame (one member) 13 and the upper frame (the other member) 11 at the upper corner of the frame, as shown in Figures 12 and 13.

[0065] -Composition of the lower corner- (Cross-sectional structure of lower frame 12) In this embodiment, the vertical sliding window consists of a vertical frame (one member) 13 and a lower frame (the other member) 12, with the vertical frame being superior to the lower frame. That is, the left and right end faces of the lower frame 12 abut against the inner circumference of the lower end portion of the vertical frame 13 to form the frame.

[0066] As shown in Figures 5(a) and 5(d), the lower frame material 121 that constitutes the lower frame 12 includes a lower frame material main body portion 121a having a hollow section, an outdoor facing wall portion 121d extending in the circumferential direction (upward) from the indoor end of the lower frame material main body portion 121a, an indoor recessed wall portion 121b extending inward from the outdoor side surface of the outdoor facing wall portion 121d, and an indoor facing wall portion 121c that is continuous with the indoor end of the indoor recessed wall portion 121b.

[0067] The lower frame member 121 is provided with engaging portions 121e and 121f at the inner circumference end (upper end) of the indoor side visible wall portion 121c and the inner circumference end (upper end) of the outdoor side visible wall portion 121d, respectively.

[0068] As shown in Figures 5(a) and 5(b), the outer peripheral member 122 constituting the resin lower member 120 of the lower frame 12 has a recessed wall portion 122a, an indoor mounting wall portion 122b extending outward (downward) from the indoor side of the recessed wall portion 122a, an outdoor mounting wall portion 122c extending outward (downward) from the outdoor side of the recessed wall portion 122a, an indoor visible wall portion 122d extending inward (upward) from the indoor side of the recessed wall portion 122a, an outdoor visible wall portion 122e extending inward (upward) from the outdoor side of the recessed wall portion 122a, and an angle portion 122f extending inward from the upper end of the indoor visible wall portion 122d.

[0069] The outer peripheral member 112 is provided with engaging portions 122h and 122i on the outer peripheral portion (lower end) of the indoor mounting wall portion 122b and the outdoor mounting wall portion 122c, respectively, and engaged portions 122j and 122k are provided on the outdoor side of the indoor visible wall portion 122d and the indoor side of the outdoor visible wall portion 122e, respectively.

[0070] The outer peripheral member 122 is attached to the lower frame member 121 by engaging the engaging portions 122h and 122i of the indoor mounting wall portion 122b and the outdoor mounting wall portion 122c with the engaging portions 121e and 121f provided on the indoor visible wall portion 121c and the outdoor visible wall portion 121d of the lower frame member 121.

[0071] The outer peripheral member 122 has an airtight seal mounting groove 122g on the outdoor side surface of the outdoor mounting wall portion 122c, and an airtight seal s21 that abuts against the lower frame 22 of the sliding door is attached to the airtight seal mounting groove 122g.

[0072] As shown in Figures 5(a) and 5(c), the inner circumferential member 123 constituting the resin lower member 120 of the lower frame 12 has a recessed wall portion 123a, an indoor mounting portion 123b extending outward from the indoor side of the recessed wall portion 123a, and an outdoor mounting portion 123c extending outward from the outdoor side of the recessed wall portion 123a, and is provided with a projection portion 123d extending outward from the outdoor end of the recessed wall portion 123a.

[0073] The inner circumferential member 123 is attached to the outer circumferential member 122 by engaging its indoor mounting portion 123b and outdoor mounting portion 123c with the engaging portions 122j and 122k provided on the indoor visible wall portion 122d and outdoor visible wall portion 122e of the outer circumferential member 122, respectively.

[0074] (Connection between the lower frame 12 and the vertical frame 13) When connecting the lower frame 12 and the vertical frame 13, the vertical frame member 131 of the vertical frame 13 has appropriate cutouts in the recessed wall portion 131a, the indoor-side visible wall portion 131b, the outdoor-side visible wall portion 131c, and the lower part of the protruding piece 131d to prevent interference with the lower frame member 121 of the lower frame 12. Furthermore, the outer peripheral member 132 of the vertical frame 13 has the angle portion 132f, the indoor-facing wall portion 132d, and the lower portion of the outdoor-facing wall portion 132e appropriately cut out.

[0075] On the other hand, the lower frame material 121 of the lower frame 12 has both ends cut vertically. Furthermore, the outer peripheral member 122 of the lower frame 12 has both ends of the exterior facing wall portion 122e cut out as appropriate.

[0076] As shown in Figures 14 and 15, the vertical frame member 131 is cut out by a length of dimension k from the lower end of the vertical frame member 131 on the indoor side of the lower part of the recessed wall portion 131a, and by a length of dimension m from the lower end of the vertical frame member 131 on the outdoor side of the lower part of the recessed wall portion 131a, beyond the mounting piece 131h.

[0077] The dimension k of the cutout in the lower indoor portion of the recessed wall 131a is approximately equal to the height dimension k' from the lower end of the mounting piece 121h of the lower frame material 121 to the lower end of the indoor visible wall portion 121c, and the dimension m of the cutout in the lower outdoor portion of the recessed wall 131a is approximately equal to the height dimension m' from the lower end of the mounting piece 121h of the lower frame material 121 to the lower surface of the main body portion 121a of the lower frame material. In other words, the lower portion of the recessed wall portion 131a of the vertical frame member 131 is cut out to match the cross-sectional shape of the lower frame 12.

[0078] The vertical frame member 131 has the lower part of the interior facing wall portion 131b cut out by a length of dimension n from the lower end of the interior wall portion 131a, the lower part of the exterior facing wall portion 131c cut out by a length of dimension p from the lower end of the interior wall portion 131a, and the lower part of the protruding piece 131d cut out by a length of dimension q from the lower end of the interior wall portion 131a.

[0079] The dimension n of the cutout in the interior-facing wall portion 131b is approximately equal to the height dimension n' of the interior-facing wall portion 121c of the lower frame member 121, and is such that when the end face of the lower frame member 121 is brought into contact with the lower inner surface of the vertical frame member 131, the interior-facing wall portion 131b of the vertical frame member 131 and the interior-facing wall portion 121c of the lower frame member 121 are continuous without interference.

[0080] Similarly, the dimension p of the cutout at the lower end of the exterior facing wall portion 131c is approximately equal to the height dimension p' of the exterior facing wall portion 121d of the lower frame member 121, and is such that when the end face of the lower frame member 121 is brought into contact with the lower inner surface of the vertical frame member 131, the exterior facing wall portion 131c of the vertical frame member 131 and the exterior facing wall portion 121d of the lower frame member 121 are continuous without interference. In this embodiment, dimensions n and p are approximately the same.

[0081] Furthermore, the dimension q of the cutout at the lower end of the protruding piece 131d is approximately equal to the dimension q' from the outer circumferential surface to the inner circumferential surface of the lower frame member 121a, and is such that the protruding piece 131d of the vertical frame member 131 does not interfere with the lower frame member 121a when the end face of the lower frame member 121 is brought into contact with the inner circumferential surface of the vertical frame member 131.

[0082] As shown in Figures 14 and 15, the outer peripheral member 132 of the vertical frame 13 has a cutout in the lower part of the angle portion 132f from the lower end by a length of dimension r.

[0083] The lower portion of the angle portion 132f of the outer peripheral member 132 of the vertical frame 13 is cut out, which allows the lower end of the outer peripheral member 132 of the vertical frame 13 to enter between the indoor-facing wall portion 121c and the outdoor-facing wall portion 121d of the lower frame material 121 when connecting the lower frame 12 and the vertical frame 13, enabling the end face of the outer peripheral member 122 of the lower frame 12 to abut and fix against the inner peripheral surface of the outer peripheral member 132 of the vertical frame 13.

[0084] The outer peripheral member 132 has a cutout in the lower part of the indoor-facing wall portion 132d by a length of dimension s from the lower end, and a cutout in the lower part of the outdoor-facing wall portion 132e by a length of dimension t from the lower end.

[0085] On the other hand, as shown in Figures 14 and 15, the outer peripheral member 122 of the lower frame 12 has the left and right ends of the exterior-facing wall portion 122e cut out by a length of dimension u from the left and right ends.

[0086] The dimension s of the cutout in the indoor-side visible wall portion 132d of the outer peripheral member 132 of the vertical frame 13 is approximately equal to the dimension s' from the position above the engaging portion 112h of the indoor-side mounting wall portion 112b of the outer peripheral member 122 of the lower frame 12 to the inner-side tip of the indoor-side visible wall portion 112d. This dimension ensures that when the end face of the outer peripheral member 122 of the lower frame material 121 is brought into contact with the lower inner surface of the outer peripheral member 132 of the vertical frame 13, the indoor-side visible wall portion 132d of the outer peripheral member 132 of the vertical frame 13 and the indoor-side visible wall portion 122d of the outer peripheral member 122 of the lower frame 12 are continuous without interference.

[0087] The dimension t of the cutout in the outdoor-facing visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13 is approximately equal to the dimension t' from the position above the engaging portion 122i of the outdoor-facing mounting wall portion 122c of the outer peripheral member 122 of the lower frame 12 to the upper surface of the visible wall portion 122a. Furthermore, the dimension u of the cutout in the outdoor-facing visible wall portion 122e of the outer peripheral member 112 of the lower frame 12 is approximately equal to the visible dimension u' of the outdoor-facing visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13.

[0088] When connecting the lower frame 12 and the vertical frame 13, as shown in Figures 16 and 17, first, the outer peripheral member 132 is attached to the indoor side inner circumference of the vertical frame member 131 of the vertical frame 13, and the outer peripheral member 122 is attached to the indoor side inner circumference of the lower frame member 121 of the lower frame 12.

[0089] The outer peripheral member 132 of the vertical frame 13 is attached to the vertical frame member 131 with the lower ends of the indoor mounting wall portion 132b and the outdoor mounting wall portion 132c aligned with the lower ends of the indoor visible wall portion 131b and the outdoor visible wall portion 131c of the vertical frame member 131.

[0090] On the other hand, the outer peripheral member 122 of the lower frame 12 is attached in the same way as the outer peripheral member 112 of the upper frame 11, so as to be located on the inner circumference side of the end of the lower frame material 121 by a length of dimension i. In other words, the outer peripheral member 122 of the lower frame 12 is formed to be twice as short as the lower frame material 121 by a dimension i.

[0091] The dimension i between the end of the outer peripheral member 122 of the lower frame 11 and the end of the lower frame material 121 is approximately equal to the dimension i' from the inner surface of the recessed wall portion 131a of the vertical frame material 131 of the vertical frame 13 to the inner surface of the recessed wall portion 132a of the outer peripheral member 132 of the vertical frame 13. This is set so that when the end face of the lower frame material 121 abuts against the inner surface of the recessed wall portion 131a of the vertical frame material 131, the end face of the outer peripheral member 122 of the lower frame 12 abuts against the inner surface of the recessed wall portion 132a of the outer peripheral member 132 of the vertical frame 13.

[0092] The outer periphery member 122 is attached to the lower frame member 121, and the two are connected by bringing the end face of the lower frame member 121, to which the outer periphery member 122 is attached, into contact with the inner periphery surface of the vertical frame member 131, to which the outer periphery member 132 is attached, and fixing them with fastening means such as screws, as shown in Figures 18 and 19.

[0093] At this time, the lower end of the outdoor-facing visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13 is cut out by a length of dimension t (the cut-out portion is called the "notch t"), and the outdoor-facing visible wall portion 122e of the outer peripheral member 112 of the lower frame 12 is cut out by a length of dimension u from the end. As a result, the end face of the outdoor-facing visible wall portion 122e of the outer peripheral member 122 of the lower frame 12 abuts against the visible wall portion 132a of the notch t of the outer peripheral member 132 of the vertical frame 13, and the outer end face of the cut-out outdoor-facing visible wall portion 122e abuts against the inner circumference of the outdoor-facing visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13, and they are connected.

[0094] As a result, the lower end of the airtight seal mounting groove 132g provided on the outdoor surface of the outdoor visible wall portion 132e of the outer peripheral member 132 of the vertical frame 13 abuts against the airtight seal mounting groove 122g provided on the outdoor surface of the outdoor visible wall portion 122e of the outer peripheral member 122 of the lower frame 12 from the inner side, thereby enabling the airtight seal s31 of the vertical frame 13 and the airtight seal s21 of the lower frame 12 to be continuous.

[0095] Subsequently, the inner circumferential member 123, which is cut perpendicularly from the inner side, is attached to the outer circumferential member 122 of the lower frame 12, and the inner circumferential member 133 of the vertical frame 13, which is cut perpendicularly from the inner side, is attached to the outer circumferential member 132 of the vertical frame 13, thereby completing the framing of the vertical frame (one member) 13 and the lower frame (the other member) 12 at the lower corner of the frame, as shown in Figures 20 and 21.

[0096] -Effects of the opening device of the embodiment- In this embodiment, the opening device is formed by creating two resin members, an inner circumferential member and an outer circumferential member, for the vertical frame 13 (one member) and the upper frame 11 (the other member). At the upper corner of the frame, the visible wall portion is cut out at the longitudinal end of the outer circumferential member of the vertical frame (one member) so that the end face of the outer circumferential member of the upper frame abuts against the visible wall portion of the outer circumferential member of the vertical frame, thereby connecting the airtight materials that are positioned along the longitudinal direction at an intermediate position in the visible direction of the resin members of the vertical frame and the upper frame.

[0097] In this embodiment, the opening device is formed by creating two resin members for the vertical frame (one member) and the lower frame (the other member): an inner circumferential member and an outer circumferential member. By simply cutting notches into the outer circumferential member of the vertical frame (one member) and the outer circumferential member of the upper frame (the other member), the end face of the airtight material placed in the vertical frame can be brought into contact with the airtight material placed in the lower frame (the other member). This allows the airtight materials, which are provided along the longitudinal direction in the intermediate portion of the visible direction of the resin members of the vertical frame and the lower frame, to be continuous at the corners.

[0098] -Other Embodiments- The dimensions of the notches in each part of the opening device are not limited to the dimensional relationships of the above embodiment, but can be set appropriately within a range that is consistent with the original. The opening device is not limited to vertical sliding windows; any type of opening device equipped with a resin frame and framed around all four sides may be used for windows, as long as it is not inconsistent.

[0099] It goes without saying that the embodiments described above are not intended to limit the inventions described in the claims, but are to be treated as illustrative examples. [Explanation of symbols]
