Embodiments for Carrying Out the Invention

[0009] Hereinafter, preferred embodiments of the furniture according to the present invention will be described in detail with reference to the accompanying drawings. For convenience, the terms "prospective direction" and "search direction" may be used hereinafter. The prospective direction is the direction along the depth of the furniture as shown by the arrow A in the figure. A surface along the prospective direction may be referred to as a prospective surface. The search direction is the direction along the up and down perpendicular to the prospective direction in the case of an object extending along the horizontal direction such as a lower frame. In the case of an object extending along the vertical direction such as a vertical frame, the horizontal direction perpendicular to the prospective direction is referred to as the search direction. A surface along the search direction may be referred to as a search surface.

[0010] Figs. 1 to 3 show the furniture which is an embodiment of the present invention. The furniture exemplified here is called a vertically sliding window and includes a frame body 10 and a shoji 20 supported so as to be openable to the outdoor side with respect to the frame body 10. The frame body 10 is constituted by surrounding the upper frame (frame member) 11, the lower frame 12, and the left and right vertical frames (frame members) 13. The upper frame 11, the lower frame 12, and the left and right vertical frames 13 constituting the frame body 10 each include a metal frame portion made of an extruded profile formed of a metal such as an aluminum alloy and a resin frame portion made of an extruded profile formed of a resin. In this embodiment, the left and right vertical frames 13 are configured to have a symmetrical shape with respect to each other. Therefore, the vertical frames 13 will be described with the same reference numerals on the left and right.

[0011] As shown in FIGS. 2, 4, and 5, the metal frame portion (metal frame forming portion) 110 of the upper frame 11 is formed by integrally molding the upper metal frame body 110a, the upper door contact wall portion 110b, and the upper resin frame support portion 110c. The upper metal frame body 110a is configured in a deformed hollow shape. An upper inner expected surface 110d and an upper outer expected surface 110e are provided on a portion on the inner peripheral side of the upper metal frame body 110a. The upper inner expected surface 110d and the upper outer expected surface 110e extend horizontally along the expected direction respectively. The upper inner expected surface 110d is provided on a portion that is closer to the indoor side and lower than the upper outer expected surface 110e. An upper stage finding surface 110f extending in the finding direction is provided between the upper inner expected surface 110d and the upper outer expected surface 110e. An outer seal member S0 is attached to a portion on the indoor side of the upper outer expected surface 110e. When the shoji 20 described later is arranged in the closed position, the outer seal member S0 abuts against the expected surface located on the outer peripheral side of the shoji 20, thereby ensuring watertightness in the indoor-outdoor direction between the shoji 20 and the outer seal member S0. The upper door contact wall portion 110b extends downward in the finding direction from the lower edge portion on the indoor side of the upper metal frame body 110a. A seal member S1 and an upper connecting fin portion 110g are provided at the lower edge portion of the upper door contact wall portion 110b. The seal member S1 is attached to the finding surface facing the outdoor side of the upper door contact wall portion 110b. When the shoji 20 described later is arranged in the closed position, the seal member S1 abuts against the finding surface facing the indoor side of the shoji 20 on the indoor space side rather than the outer seal member S0, thereby ensuring airtightness and watertightness in the indoor-outdoor direction between the shoji 20 and the seal member S1. The upper connecting fin portion 110g extends downward in the finding direction after bending slightly toward the indoor side at a portion lower than the seal member S1. The upper resin frame support portion 110c extends in the finding direction from the upper edge portion on the indoor side of the upper metal frame body 110a toward the indoor side, and has an upper resin insertion groove 110h opening downward at the edge portion located on the indoor side.

[0012] The resin frame part (resin frame forming part) 112 of the upper frame 11 has an upper resin frame main body 112a, an upper inner protruding part 112b, a main body contact fin part 112c, an upper insertion fin part 112d, and an upper mounting plate part 112e. The upper resin frame main body 112a has a substantially rectangular hollow shape with a vertically long cross-section in the finding direction. An upper accommodation forming fin part 112f is provided at a lower part on the finding surface of the upper resin frame main body 112a facing the outdoor. The upper accommodation forming fin part 112f extends toward the outdoor and then extends upward in a bent manner, and forms an upper accommodation part 112g that opens toward the outer peripheral side between the upper resin frame main body 112a. The dimensions of the upper accommodation part 112g are configured such that the upper connecting fin part 110g can be inserted. The upper inner protruding part 112b has a substantially rectangular hollow cross-section and is provided so as to protrude into the room from an upper part of the upper resin frame main body 112a and facing the indoor. The main body contact fin part 112c extends in the finding direction from the upper edge part located on the outdoor side of the upper resin frame main body 112a toward the outer periphery. The dimension of the main body contact fin part 112c along the finding direction is set such that when the upper connecting fin part 110g is accommodated in the upper accommodation part 112g, the upper edge is slightly lower than the lower surface of the upper resin frame support part 110c. The upper insertion fin part 112d extends in the finding direction upward from the upper edge part on the indoor side of the upper resin frame main body 112a. This upper insertion fin part 112d is provided so as to be insertable into the upper resin insertion groove 110h when the upper connecting fin part 110g is accommodated in the upper accommodation part 112g. The upper mounting plate part 112e extends in the looking-in direction into the room from the lower edge part on the indoor side of the upper inner protruding part 112b.

[0013] This resin frame part 112 is attached to the metal frame part 110 by inserting the upper insertion fin part 112d into the upper resin insertion groove 110h, inserting the upper connecting fin part 110g into the upper accommodation part 112g, and screwing a screw member (fastener) N1 into the upper connecting fin part 110g from the outdoor side in the looking-in direction through the upper accommodation forming fin part 112f. The tip of the screw member N1 terminates in the hollow part of the upper metal frame main body 110a. In the metal frame part 110 with the resin frame part 112 attached, the lower surface of the upper door contact wall part 110b and the finding surface facing the indoor are covered by the resin frame part 112.

[0014] The metal frame portion 120 of the lower frame 12 is formed by integrally molding the lower metal main body 120a, the lower door contact wall portion 120b, and the lower resin frame support portion 120c. The lower metal main body 120a is configured to have a lower inner prospective surface 120d, a lower outer prospective surface 120e, and a lower-stage portion finding surface 120f. The lower inner prospective surface 120d and the lower outer prospective surface 120e each extend horizontally along the prospective direction. The lower inner prospective surface 120d is provided at a portion that is closer to the indoor side and above the lower outer prospective surface 120e. The lower-stage portion finding surface 120f extends in the finding direction between the lower inner prospective surface 120d and the lower outer prospective surface 120e. The dimension along the prospective direction of the lower inner prospective surface 120d is substantially equal to the dimension along the prospective direction of the upper inner prospective surface 110d, and the dimension along the prospective direction of the lower outer prospective surface 120e is substantially equal to the dimension along the prospective direction of the upper outer prospective surface 110e. The lower door contact wall portion 120b extends upward in the finding direction from an edge portion located on the indoor side of the lower metal main body 120a. A seal member S1 is attached to a portion facing the outdoor side at the upper edge portion of the lower door contact wall portion 120b. The seal member S1 forms a series with the seal member S1 attached to the upper frame 11 and the seal member S1 attached to the vertical frame 13 described later. That is, when the sliding door 20 described later is disposed at the closed position, the seal member S1 abuts against a finding surface facing the indoor side of the sliding door 20, thereby ensuring airtightness and watertightness in the indoor-outdoor direction between the sliding door 20 and the seal member S1. A cover engagement protrusion 120g is provided at a portion facing the indoor side at the upper edge portion of the lower door contact wall portion 120b. The lower resin frame support portion 120c extends in the prospective direction toward the indoor side from a position that is approximately at the center in the height direction on a finding surface facing the indoor side of the lower door contact wall portion 120b. A resin contact plate portion 120h and a lower resin insertion groove 120j are provided in the lower resin frame support portion 120c. The resin contact plate portion 120h extends upward from a portion that is approximately in the middle on the upper surface of the lower resin frame support portion 120c and then inclines so as to gradually become upward toward the indoor side. The lower resin insertion groove 120j is provided at an edge portion located on the indoor side of the lower resin frame support portion 120c and opens upward.

[0015] The resin frame portion 122 of the lower frame 12 is formed by integrally molding a lower resin frame body 122a, a lower resin engaging piece 122b, a lower resin support piece 122c, and a lower insertion fin portion 122d. The lower resin frame body 122a extends along the prospective direction and is formed to have a dimension that protrudes into the room from the lower door contact wall portion 120b of the metal frame portion 120 beyond the lower resin insertion groove 120j. The half portion located on the outdoor side of the lower resin frame body 122a is provided to be one step lower than the half portion located on the indoor side. The lower resin engaging piece 122b extends obliquely downward from a portion closer to the outdoor side on the lower surface of the lower resin frame body 122a so as to gradually become closer to the indoor side. The lower resin engaging piece 122b is provided with a lower engaging groove portion 122e at a portion that becomes the outdoor side at the lower edge portion. The lower resin support piece 122c extends downward in the prospective direction from a portion that is approximately in the middle on the lower surface of the lower resin frame body 122a. The lower insertion fin portion 122d extends downward in the prospective direction from a portion that is closer to the indoor side than the lower resin support piece 122c on the lower surface of the lower resin frame body 122a.

[0016] This resin frame portion 122 is attached to the metal frame portion 120 by engaging the lower engaging groove portion 122e with the cover engaging protrusion 120g and inserting the lower insertion fin portion 122d into the lower resin insertion groove 120j. At this time, the lower resin support piece 122c is in a state of being in contact with and supported by the upper edge portion of the lower resin frame support portion 120c. In the metal frame portion 120 with the resin frame portion 122 attached, the upper edge surface of the lower door contact wall portion 120b and the upper surface of the portion located more indoors than this are covered by the resin frame portion 122.

[0017] The metal frame part (metal frame forming part) 130 of the vertical frame 13 is formed by integrally molding a vertical metal frame main body 130a, an outer finding wall part 130b, an inner finding wall part 130c, and a vertical door contact wall part 130d. The vertical metal frame main body 130a is in the form of a flat plate extending substantially vertically along the prospective direction. On the edge located on the indoor side on the prospective surface facing the inner peripheral side of the vertical metal frame main body 130a, a vertical resin frame insertion groove 130e opening toward the inner peripheral side is provided. The outer finding wall part 130b extends in the prospective direction at the edge located on the outdoor side of the vertical metal frame main body 130a. The inner finding wall part 130c extends in the prospective direction from the edge located on the indoor side of the vertical metal frame main body 130a toward the outer periphery. The vertical door contact wall part 130d extends in the finding direction toward the inner peripheral side from the part closer to the indoor side on the prospective surface on the inner peripheral side of the vertical metal frame main body 130a. A seal member S1, a vertical connecting fin part 130f, and an intermediate prospective wall part 130g are provided in the part on the inner peripheral side of the vertical door contact wall part 130d. The seal member S1 is part of a series with the seal member S1 attached to the upper door contact wall part 110b of the upper frame 11 and the lower door contact wall part 120b of the lower frame 12, and is attached to the finding surface facing the outdoor side of the vertical door contact wall part 130d. The vertical connecting fin part 130f extends in the finding direction inward after bending slightly toward the indoor side in the part on the inner peripheral side of the seal member S1. The intermediate prospective wall part 130g extends in the finding direction toward the outdoor side from the part on the outer peripheral side of the seal member S1 on the finding surface facing the outdoor side of the vertical door contact wall part 130d, and then bends toward the outer periphery, forming a hollow part with a rectangular cross-section between it and the vertical metal frame main body 130a.

[0018] The resin frame portion (resin frame forming portion) 132 of the vertical frame 13 is formed by integrally molding a vertical resin frame main body 132a, a vertically inward protruding portion 132b, an inward insertion fin portion 132c, and a mounting plate portion 132d. The vertical resin frame main body 132a has a substantially rectangular hollow shape with a cross-section that is longitudinally long in the finding direction. A vertically receiving forming fin portion 132e is provided at a portion on the inner peripheral side of the finding surface facing the outside of the vertical resin frame main body 132a. The vertically receiving forming fin portion 132e extends toward the outside and then bends toward the outer peripheral side, and forms a vertically receiving portion 132f that opens toward the outer peripheral side between the vertically receiving forming fin portion 132e and the vertical resin frame main body 132a. The dimensions of the vertically receiving portion 132f are configured such that the vertical connecting fin portion 130f can be inserted therein. The vertically inward protruding portion 132b has a substantially rectangular hollow cross-section and is provided so as to protrude into the room from a portion on the outer peripheral side of the vertical resin frame main body 132a and facing the inside of the room. The inward insertion fin portion 132c extends in the finding direction from the edge portion on the outer peripheral side and the indoor side of the vertically inward protruding portion 132b toward the outer periphery. The mounting plate portion 132d extends in the prospective direction from the edge portion located on the inner peripheral side and the indoor side of the vertically inward protruding portion 132b toward the inside of the room.

[0019] This resin frame portion 132 is attached to the metal frame portion 130 by inserting the inward insertion fin portion 132c into the vertical resin frame insertion groove 130e, inserting the vertical connecting fin portion 130f into the vertically receiving portion 132f, and screwing a screw member N1 into the vertical connecting fin portion 130f from the outside toward the prospective direction through the vertically receiving forming fin portion 132e. The tip of the screw member N1 terminates in the hollow portion of the vertical metal frame main body 130a. In the metal frame portion 130 with the resin frame portion 132 attached, the prospective surface located on the inner peripheral side of the vertical door contact wall portion 130d and the finding surface facing the inside of the room are covered by the resin frame portion 132.

[0020] The shoji 20 is configured by assembling upper and lower horizontal frames (frame materials) 22 and left and right vertical frames (frame materials) 23 around the four sides of a panel 21 such as a multilayer glass having a square shape. The upper and lower horizontal frames 22 and the left and right vertical frames 23 that constitute the shoji 20 are each configured to include an outdoor metal frame portion formed of a metal such as an aluminum alloy and an indoor resin frame portion formed of a resin. In the present embodiment, the upper and lower horizontal frames 22 are configured to have a symmetrical shape with respect to each other. Similarly, the left and right vertical frames 23 are configured to have a symmetrical shape with respect to each other. Therefore, the horizontal frames 22 will be described with the same reference numerals for the upper and lower parts, and the vertical frames 23 will be described with the same reference numerals for the left and right parts.

[0021] The metal frame portion (metal frame forming portion) 220 of the horizontal frame 22 is formed by integrally molding a horizontal metal frame base portion 220a, a horizontal panel support wall portion (panel support piece) 220b, and a horizontal shoji support portion 220c. The horizontal metal frame base portion 220a has a substantially rectangular hollow shape with a horizontally long cross-section in the prospective direction. An edge pressing strip 221 is attached to an edge located on the outdoor side on the inner peripheral side of the horizontal metal frame base portion 220a via an edge pressing strip mounting portion 220d. The edge pressing strip 221 is provided so as to protrude inward from the prospective surface on the inner peripheral side of the horizontal metal frame base portion 220a. The horizontal panel support wall portion 220b extends in the prospective direction inward from an edge located on the inner peripheral side and indoor side of the horizontal metal frame base portion 220a. The protruding dimension of the horizontal panel support wall portion 220b from the horizontal metal frame base portion 220a to the inner peripheral side is substantially equal to the protruding dimension of the edge pressing strip 221 from the horizontal metal frame base portion 220a to the inner peripheral side. The horizontal shoji support portion 220c has a substantially rectangular hollow shape with a horizontally long cross-section in the prospective direction, and protrudes indoors from a portion on the inner peripheral side on the indoor-facing prospective surface of the horizontal panel support wall portion 220b. The horizontal resin frame insertion portion 220e and the horizontal resin frame engaging fin portion 220f are provided on the horizontal shoji support portion 220c. The horizontal resin frame insertion portion 220e is provided at an edge located on the inner peripheral side and indoor side of the horizontal shoji support portion 220c. The horizontal resin frame engaging fin portion 220f extends in the prospective direction inward from an edge located on the inner peripheral side and outdoor side of the horizontal shoji support portion 220c. A horizontal engaging protrusion 220g is provided on a portion located on the outer peripheral side rather than on the inner peripheral side facing prospective surface of the horizontal resin frame engaging fin portion 220f and facing indoors. An upper edge portion and a lower edge portion of the panel 21 are sandwiched between the edge pressing strip 221 and the horizontal panel support wall portion 220b of the metal frame portion 220 via a sealing material S2.

[0022] The resin frame portion (resin frame forming portion) 222 of the horizontal frame 22 is formed by integrally molding a resin frame base portion 222a, an insertion fin portion 222b, an engagement fin portion 222c, and a locating wall portion 222d. The resin frame base portion 222a is in the form of a plate that extends substantially horizontally along the prospective direction. The insertion fin portion 222b extends in the locating direction from the edge located on the indoor side of the resin frame base portion 222a toward the outer peripheral side. The extending edge of the insertion fin portion 222b is configured to be insertable into a horizontal resin frame insertion portion 220e provided in the horizontal shutter support portion 220c. The engagement fin portion 222c extends from the edge located closer to the outdoor side of the resin frame base portion 222a toward the outer peripheral side and then bends toward the outside. This engagement fin portion 222c can engage with a horizontal engagement protrusion 220g of the horizontal shutter support portion 220c when the insertion fin portion 222b is inserted into the horizontal resin frame insertion portion 220e. The locating wall portion 222d protrudes from the edge located on the outdoor side of the resin frame base portion 222a toward the outer peripheral side.

[0023] This resin frame portion 222 is attached to the metal frame portion 220 by engaging the engagement fin portion 222c with the horizontal engagement protrusion 220g with the insertion fin portion 222b inserted into the horizontal resin frame insertion portion 220e. In the metal frame portion 220 with the resin frame portion 222 attached, the prospective surface on the inner peripheral side of the horizontal shutter support portion 220c is covered by the resin frame portion 222.

[0024] The metal frame portion (metal frame forming portion) 230 of the vertical frame 23 is formed by integrally molding a vertical metal frame base portion 230a, a vertical panel support wall portion (panel support piece) 230b, and a vertical shoji support portion 230c. The vertical metal frame base portion 230a is in the form of a plate extending vertically along the prospective direction. On this vertical metal frame base portion 230a, an edge pressing strip 221 is attached via a vertical edge pressing strip mounting portion 230d to an edge located on the outdoor side on the inner peripheral side. The edge pressing strip 231 is the same as the one attached to the horizontal frame 22 and is provided so as to protrude inward from the prospective surface on the inner peripheral side of the vertical metal frame base portion 230a. An outer sealing member S3 is attached to the prospective surface on the outer peripheral side of the vertical metal frame base portion 230a. The outer sealing member S3 ensures watertightness in the indoor-outdoor direction between the vertical frame 13 by coming into contact with the prospective surface on the inner peripheral side of 130g in the metal frame portion 130 of the vertical frame 13 when the shoji 20 is arranged in the closed position. The vertical panel support wall portion 230b extends in the finding direction from an edge located on the inner peripheral side and on the indoor side of the vertical metal frame base portion 230a toward the inner peripheral side. The protruding dimension of the vertical panel support wall portion 230b from the vertical metal frame base portion 230a toward the inner peripheral side is substantially equal to the protruding dimension of the edge pressing strip 231 from the vertical metal frame base portion 230a toward the inner peripheral side. The vertical shoji support portion 230c has a substantially rectangular hollow shape with a vertically long cross-section in the prospective direction and protrudes into the room from a portion on the inner peripheral side on the finding surface facing the room of the vertical panel support wall portion 230b. The vertical resin frame insertion portion 230e and the vertical resin frame engaging fin portion 230f are provided on the vertical shoji support portion 230c. The vertical resin frame insertion portion 230e is provided at an edge located on the inner peripheral side and on the indoor side of the vertical shoji support portion 230c. The vertical resin frame engaging fin portion 230f extends in the finding direction from an edge located on the inner peripheral side and on the outdoor side of the vertical shoji support portion 230c toward the inner peripheral side. A vertical engaging protrusion 230g is provided on a portion located on the outer peripheral side rather than on the finding surface facing the inner peripheral side of the vertical resin frame engaging fin portion 230f and facing the room. Both side edges of the panel 21 are clamped between the edge pressing strip 231 and the vertical panel support wall portion 230b of this metal frame portion 230 via a sealing material S2.

[0025] The resin frame portion (resin frame forming portion) 232 of the vertical frame 23 has the same cross-sectional shape as the resin frame portion 222 of the horizontal frame 22. That is, the resin frame portion 232 is formed by integrally molding a resin frame base portion 222a, an insertion fin portion 222b, an engagement fin portion 222c, and a finding wall portion 222d.

[0026] This resin frame portion 232 is attached to the metal frame portion 230 by engaging the engagement fin portion 222c with the vertical engagement protrusion 230g in a state where the insertion fin portion 222b is inserted into the vertical resin frame insertion portion 230e. In the metal frame portion 230 to which the resin frame portion 232 is attached, the prospective surface on the inner peripheral side of the vertical shutter support portion 230c is covered by the resin frame portion 232. Note that the reference sign H in FIG. 3 is an operation handle attached to one of the vertical frames 23.

[0027] In this fitting, the shutter 20 is disposed on the frame body 10 via a link mechanism L called a friction stay between the upper outer prospective surface 110e of the upper frame 11 and the horizontal shutter support portion 220c of the upper horizontal frame 22, and between the 120d of the lower frame 12 and the horizontal shutter support portion 220c of the lower horizontal frame 22. When the shutter 20 is pushed open to the outdoor side via the operation lever H, the frame body 10 can be opened. In a state where the shutter 20 is disposed at the closed position, the seal members S1 are respectively pressed against the finding surfaces of the metal frame portions 220 and 230 constituting the peripheral frames 22 and 23, and the airtightness and watertightness between the frame body 10 are ensured.

[0028] Moreover, as described above, the screw member N1 that connects the metal frame portion 110 and the resin frame portion 112 of the upper frame 11 and the screw member N1 that connects between the metal frame portion 130 and the resin frame portion 132 of the vertical frame 13 are both screwed at positions on the indoor space side with reference to the position where the seal member S1 abuts. Therefore, even when through holes are formed in the resin frame portion 132 and the metal frame portion 130 by screwing the screw member N1, there is no risk that the through holes will affect the sealing performance. In addition, since the screw members N1 are all screwed along the prospective direction when viewed from the outdoor side, it is difficult to visually recognize the screw members N1 from the indoor side, and there is no concern that the appearance quality will be impaired. Further, since the resin frame portions 112, 122, and 132 are arranged on the indoor side at the four circumferences of the frame body 10, and the resin frame portions 222 and 232 are arranged on the indoor side at the four circumferences of the shoji 20, in other words, since the metal frame portions 110, 120, and 130 and the metal frame portions 220 and 230 are not exposed indoors, it is advantageous in terms of heat insulation and dew prevention.

[0029] In the above-described embodiment, the upper frame 11 is provided with portions (upper connecting fin portions 110g, upper housing forming fin portions 112f) that overlap each other in the prospective direction between the metal frame portion 110 and the resin frame portion 112, and the metal frame portion 110 and the resin frame portion 112 are connected by screwing the screw member N1 from the outdoor side along the prospective direction. However, the metal frame portion 130 and the resin frame portion 132 are also provided with portions (vertical connecting fin portions 130f, vertical housing forming fin portions 132e) that overlap each other in the prospective direction, and the metal frame portion 130 and the resin frame portion 132 are connected by screwing the screw member N1 from the outdoor side along the prospective direction. However, the present invention is not limited to this, as in the case of the fitting shown in the modified examples in FIGS. 8 and 9.

[0030] That is, in the fitting of the modification example, in the metal frame portion 110 of the upper frame 11, an upper projected connecting fin portion (overlapping portion) 110k extending inwardly along the expected direction is formed at the lower edge portion of the upper door contact wall portion 110b. Instead of the upper accommodation forming fin portion 112f and the upper accommodation portion 112g, in the resin frame portion 112 of the upper frame 11, an upper overlapping fin portion (overlapping portion) 112j extending in the expected direction is provided by providing a recess 112h on the finding surface facing the outside at the lower end portion of the upper resin frame main body 112a. Further, at the lower end portion of the upper resin frame main body 112a, upper cap mounting wall portions 112k are provided so as to project downward from the edge portions on both sides. A cap member (cover member) 113 is detachably mounted between the upper cap mounting wall portions 112k.

[0031] The metal frame portion 110 and the resin frame portion 112 constituting the upper frame 11 of the modification example are configured such that the configurations other than those described above are the same as those of the embodiment. Therefore, the same reference numerals are given to the same configurations as those of the embodiment, and the detailed description thereof is omitted.

[0032] This resin frame portion 112 is mounted on the metal frame portion 110 by inserting the upper insertion fin portion 112d into the upper resin insertion groove 110h, overlapping the upper overlapping fin portion 112j with the upper projected connecting fin portion 110k, and screwing a screw member N1 from the inner peripheral side (downward) into the upper projected connecting fin portion 110k in the finding direction through the upper overlapping fin portion 112j. After the screw member N1 is screwed, the cap member 113 is mounted between the upper cap mounting wall portions 112k. In the metal frame portion 110 with the resin frame portion 112 mounted thereon, the lower surface of the upper door contact wall portion 110b and the finding surface facing the interior are covered by the resin frame portion 112.

[0033] Similarly, in the metal frame portion 130 of the vertical frame 13, a vertical projected connecting fin portion (overlapping portion) 130h extending indoors along the projected direction is formed at the inner peripheral edge portion of the vertical door contact wall portion 130d. In the resin frame portion 132 of the vertical frame 13, instead of the vertical accommodation forming fin portion 132e and the vertical accommodation portion 132f, a vertical overlapping fin portion (overlapping portion) 132h extending in the projected direction is provided by providing a recess 132g on the finding surface facing the outside at the inner peripheral edge portion of the vertical resin frame main body 132a. Further, at the inner peripheral end portion of the vertical resin frame main body 132a, vertical cap mounting wall portions 132j are provided so as to project downward from the edge portions on both sides. A cap member (cover member) 133 is detachably mounted between the vertical cap mounting wall portions 132j.

[0034] The metal frame portion 130 and the resin frame portion 132 constituting the vertical frame 13 of the modification are configured such that the configurations other than those described above are the same as those of the embodiment. Therefore, the same reference numerals are given to the same configurations as those of the embodiment, and the detailed description thereof is omitted.

[0035] This resin frame portion 132 is mounted on the metal frame portion 130 by inserting the inner insertion fin portion 132c into the vertical resin frame insertion groove 130e, overlapping the vertical overlapping fin portion 132h with the vertical projected connecting fin portion 130h, and screwing a screw member N1 from the inner peripheral side in the projected direction into the vertical projected connecting fin portion 130h through the vertical overlapping fin portion 132h. After screwing the screw member N1, the cap member 133 is mounted between the vertical cap mounting wall portions 132j. In the metal frame portion 130 with the resin frame portion 132 mounted thereon, the projected surface located on the inner peripheral side of the vertical door contact wall portion 130d and the finding surface facing the indoors are covered by the resin frame portion 132.

[0036] In the fitting of this modification example, when the shoji 20 is arranged in the closed position, the seal members S1 are respectively pressed against the finding surfaces of the metal frame portions 220 and 230 that constitute the four peripheral frames 22 and 23, ensuring the airtightness and watertightness between the frame body 10. Moreover, as described above, the screw member N1 that connects the metal frame portion 110 and the resin frame portion 112 of the upper frame 11 and the screw member N1 that connects between the metal frame portion 130 and the resin frame portion 132 of the vertical frame 13 are both screwed at positions on the indoor space side with reference to the positions where the seal member S1 abuts. Therefore, even when through holes are formed in the resin frame portion 132 and the metal frame portion 130 by screwing the screw member N1, there is no risk that the through holes will affect the sealing performance. In addition, since the cap members 113 and 133 are attached to the portions where the screw member N1 is screwed, it is difficult to visually recognize the screw member N1, and there is no concern that the appearance quality will be impaired. Furthermore, since the resin frame portions 112, 122, and 132 are arranged on the indoor side around the frame body 10, and the resin frame portions 222 and 232 are arranged on the indoor side around the shoji 20, in other words, since the metal frame portions 110, 120, 130 and the metal frame portions 220, 230 are not exposed indoors, it is advantageous in terms of heat insulation and dew prevention.

[0037] In the above-described embodiment, a vertically sliding window is exemplified. However, as long as the shoji is supported by the frame body so as to be openable and closable, it can also be applied to other fittings. Also, although a screw member is exemplified as the fixing tool, other fixing tools such as rivets may be applied. Furthermore, although only the upper frame and the lower frame are connected by the fixing tool between the metal frame forming portion and the resin frame forming portion, the same can be applied to the lower frame as well.

[0038] As described above, the fitting according to the present invention includes a frame body, a shoji door disposed so as to be openable and closable with respect to the frame body, and a seal member provided on the frame body. The frame material constituting the frame body has a metal frame molded portion formed of metal and a resin frame molded portion formed of resin. The seal member is provided at a position where it abuts against the shoji door when the shoji door is disposed at the closed position with respect to the frame body. The metal frame molded portion and the resin frame molded portion are connected to each other by a fixture at a position on the indoor space side with reference to the position where the seal member abuts. According to this invention, since the fixture is provided at a position on the indoor space side with reference to the position where the seal member abuts, even when a through hole is formed by providing the fixture, the sealing performance is not affected. Thereby, it becomes possible to improve the heat insulation property without impairing the sealing performance.

[0039] Further, in the present invention, in the fitting described above, the metal frame molded portion and the resin frame molded portion have overlapping portions in the prospecting direction, and the fixture is mounted along the prospecting direction from the outdoor side to these overlapping portions.
