[0001] The present invention relates to building materials, and more particularly to building materials such as row windows and stepped windows that are constructed by connecting a plurality of frames to each other. [Background technology]

[0002] One type of fixture of this type involves placing vertical beam members or upright members between adjacent frame bodies, and connecting the vertical frames of each frame body to these vertical beam members or upright members (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-54546 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in these building fixtures, vertical beam members and upright members are interposed between the vertical frames, which not only increases manufacturing costs but also raises concerns about the overall dimensions becoming larger.

[0005] In view of the above-mentioned circumstances, the present invention has an object to provide a fitting that can suppress increases in manufacturing costs and large external dimensions. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the fitting of the present invention is a fitting constructed by connecting frame bodies with panels arranged inside them in a side-by-side state, and is characterized in that, on at least one of the frame bodies, a first inner periphery edge portion located on the inner periphery of the shaped member supporting the edge portion of the surface of the panel facing the outside of the room and a second inner periphery edge portion located on the inner periphery of the shaped member supporting the edge portion of the surface of the panel facing the inside of the room are each positioned at the same position in the projection direction as the frame material edge portion located on the inner periphery of the visible surface of the frame material facing the inside of the room, or are positioned more outer than the frame material edge portion, and adjacent frame members of the frame body are provided with engaging pieces that extend in the projection direction from the opposing visible surfaces and then bend and extend in the projection direction, and the adjacent frame members are prevented from moving away from each other by engaging the engaging piece provided on one frame member between the visible surface and the engaging surface with the engaging piece provided on the other frame member. Effect of the Invention

[0007] According to the present invention, by engaging the engaging pieces aligned in the projecting direction with each other, it is possible to prevent adjacent frame bodies from moving away from each other, making it possible to connect side-by-side frame bodies without the need for vertical frame members or upright members, thereby preventing increases in manufacturing costs and external dimensions.

The protruding dimension of the lower outer panel clamping wall 13d from the lower base wall 13a is approximately the same as the protruding dimension of the lower inner panel clamping wall 13c.

[0014] The first vertical frame (hereinafter, when distinguished, referred to as the first outer vertical frame 14) arranged on the outer periphery of the building material and the first vertical frame (hereinafter, when distinguished, referred to as the first inner vertical frame 15) connected to the second vertical frame 44 of the second stage window W2 are arranged so that they are continuous between the vertical sliding window M11 of the first stage window W1 and the first fixed window M12.

[0015] The first outer vertical frame 14 has an outer base wall portion 14a, an outer door stop wall portion 14b, and an outer frame inner sight wall portion 14c. The outer base wall portion 14a corresponds to the lower base wall portion 13a of the first lower frame 13. The outer door stop wall portion 14b and the outer frame inner sight wall portion 14c correspond to the upper door stop wall portion 11c and the upper inner sight wall portion 11e of the first upper frame 11, respectively. The outer base wall portion 14a extends almost vertically along the projection direction. An attachment hook 14d is provided on the edge portion that faces the outside of the room on the projection surface that is the inner periphery of the outer base wall portion 14a. The attachment hook 14d protrudes toward the inner periphery and then bends toward the inside of the room. The outer door stop wall 14b extends from the portion corresponding to the upper door stop wall 11c of the first upper frame 11 on the inner peripheral side of the outer base wall 14a. The protruding dimension of the outer door stop wall 14b from the outer base wall 14a is set to be larger than the protruding dimension of the upper door stop wall 11c from the upper base wall 11a. The inner seal member S1 is attached only to the portion above the first interlining 12 at the almost middle portion of the protruding surface of the outer door stop wall 14b facing the outside of the room, via the seal attachment portion 14e. The outer frame inner sight wall 14c extends in the sight direction from the edge portion located on the indoor side of the outer base wall 14a toward the inner peripheral side and the outer peripheral side. The protruding dimension of the outer frame inner sight wall 14c toward the inner peripheral side is approximately equal to the protruding dimension of the outer door stop wall 14b.

[0016] The first inner vertical frame 15 has an inner base wall portion 15a, an inner door stop wall portion 15b, and an inner frame inner sight wall portion 15c. The inner base wall portion 15a, the inner door stop wall portion 15b, and the inner frame inner sight wall portion 15c correspond to the outer base wall portion 14a, the outer door stop wall portion 14b, and the outer frame inner sight wall portion 14c of the first outer vertical frame 14, respectively. The inner base wall portion 15a extends almost vertically along the projection direction. An attachment hook 15d similar to that of the first outer vertical frame 14 is provided on the edge portion that faces the outside of the room on the projection surface that is the inner periphery of the inner base wall portion 15a. The inner door stop wall portion 15b extends toward the inner periphery from a portion that corresponds to the outer door stop wall portion 14b of the first outer vertical frame 14 on the projection surface that is the inner periphery of the inner base wall portion 15a. The protruding dimension of the inner door stop wall 15b from the inner base wall 15a is almost equal to the protruding dimension of the upper door stop wall 11c from the upper base wall 11a. The inner seal member S1 is attached to the extending edge of the inner door stop wall 15b, which faces the outside of the room, only above the first flap 12, via the seal mounting part 15e. The inner frame inner sight wall 15c extends in the sight direction from the edge located on the inside of the room of the inner base wall 15a toward the inner periphery. The protruding dimension of the inner frame inner sight wall 15c toward the inner periphery is almost equal to the protruding dimension of the inner door stop wall 15b. As is clear from the figure, the inner frame inner sight wall 15c of this embodiment is configured to have a plate thickness larger than that of the outer frame inner sight wall 14c (almost three times as thick in the illustrated example). An internal locking protrusion 15f is provided on the interior side of the extended edge of the inner frame inner sight wall 15c. The internal locking protrusion 15f has an engagement recess 15g and an introduction inclined surface 15h on the inner peripheral side, and protrudes toward the interior side of the room.

[0017] In addition, the first inner vertical frame 15 is provided with an inner engagement piece 15i and an inner overlapping piece 15j on the outer peripheral surface of the inner base wall portion 15a. The inner engagement piece 15i extends from a portion that is closer to the room than the edge portion located on the room side of the inner base wall portion 15a toward the outer peripheral side, then bends and extends in the inner direction toward the room side. The inner overlapping piece 15j extends from a portion that is closer to the room than the edge portion located on the room side of the inner base wall portion 15a toward the outer peripheral side. The protruding dimension of the inner overlapping piece 15j from the inner base wall portion 15a is approximately equal to the protruding dimension of the inner engagement piece 15i. A fitting groove portion (fitting portion) 15k is provided in the portion located at the connecting portion with the inner base wall portion 15a on the inner surface of the inner overlapping piece 15j facing the room.

[0018] In the first-stage window W1 having the first upper frame 11, first interlining 12, first lower frame 13, and first vertical frames 14, 15 configured as described above, the first upper frame 11, the first interlining 12, and the first vertical frames 14, 15 form an upper frame body 10A, and the first interlining 12, the first lower frame 13, and the first vertical frames 14, 15 form a lower frame body 10B.

[0019] In the upper frame body 10A, a link mechanism 1 called a friction stay is interposed between the upper base wall portion 11a of the first upper frame 11 and the upper frame 21 of the shoji screen 20, and between the middle base wall portion 12a of the first transom 12 and the lower frame 22 of the shoji screen 20, respectively, to form a vertical sliding window M11 that can be opened to the outside. When the shoji screen 20 is placed in the closed position, approximately equal gaps are secured between the four peripheral projection surfaces on the inner periphery of the frame body 10A and the four peripheral projection surfaces on the outer periphery of the shoji screen 20. Therefore, the inner seal members S1 provided on each of the first upper frame 11, the first transom 12, and the first vertical frames 14, 15 are in a state of continuous contact with the projection surfaces of the upper frame 21, the lower frame 22, and the left and right vertical frames 23, 23 facing the room. In addition, an upper seal member 11g provided on the first upper frame 11 is interposed between the first upper frame 11 and the upper frame 21, and side seal members 23a, 23a provided on the vertical frames 23, 23 are interposed between the first vertical frames 14, 15 and the vertical frames 23, 23. Therefore, watertightness and airtightness in the indoor and outdoor directions can be ensured. In addition, a folding screen door 30 is stored between the outer door contact wall 14b of the first outer vertical frame 14 and the inner sight wall 14c of the outer frame in the part of the upper frame body 10A that is on the indoor side of the shoji screen 20. By pulling out this screen door 30, the upper frame body 10A can be covered with a mesh body 33 with the shoji screen 20 open, allowing ventilation between the indoor and outdoor without causing a situation where foreign objects such as insects enter the room.

[0020] As is clear from the figure, in the first inner vertical frame 15, the inner peripheral edge (first inner peripheral edge) 25a of the batten 25 supporting the edge portion of the surface of the panel 24 facing the outside and the inner peripheral edge (second inner peripheral edge) 23b of the vertical frame 23 supporting the edge portion of the surface of the panel 24 facing the inside are both located on the same vertical plane along the projection direction with respect to the edge (frame material edge) 15m located on the innermost side of the inner frame inner sight wall 15c. Similarly, in the first outer vertical frame 14, the inner peripheral edge 25a of the batten 25 supporting the edge portion of the surface of the panel 24 facing the outside and the inner peripheral edge 23b of the vertical frame 23 supporting the edge portion of the surface of the panel 24 facing the inside are both located on the outer peripheral side with respect to the edge (frame material edge) 14f located on the innermost side of the outer frame inner sight wall 14c. Therefore, when viewed from inside the room, the vertical frames 23, 23 and the edges 25, 25 of the shoji screen 20 do not extend beyond the first vertical frames 14, 15 and are not exposed on the inner periphery, which is advantageous in terms of appearance quality.

[0021] On the other hand, in the lower frame 10B, the attachments 16 are attached to the first outer vertical frame 14 and the first inner vertical frame 15, and the panel P1 is disposed between the attachments 16, the first transom 12, and the first bottom frame 13 to form the first fixed window M12. The outer dimensions of the panel P1 are almost the same as the panel P1 of the shoji screen 20 disposed in the upper frame 10A. The attachments 16 are symmetrical on the left and right, and have an attachment base plate 16a, a vertical inner panel clamping plate 16b, and a support plate 16c. The attachment base plate 16a and the vertical inner panel clamping plate 16b correspond to the middle panel cover wall 12b and the middle inner panel clamping wall 12f of the first transom 12, respectively. The attachment base plate 16a extends almost vertically along the projection direction. The attachment base plate 16a is provided with a flange 12g, an engagement leg 16d, and a fixed leg 16e. The flange 12g has a mounting portion 12h and a panel clamping portion 12i, similar to the flange 12 provided on the first transom 12, and is attached to the exterior side of the inner peripheral surface of the attachment base plate 16a. The engagement leg 16d and the fixed leg 16e extend in the viewing direction from the outer peripheral surface of the attachment base plate 16a toward the outer peripheral side. The engagement leg 16d extends from the exterior side toward the outer peripheral side. The extended edge of the engagement leg 16d is provided with an engagement claw portion 16f that is bent toward the exterior side and can engage with the attachment hooks 14d, 15d of the first vertical frames 14, 15. The fixed leg 16e extends from the edge of the attachment base plate 16a on the room side toward the outer periphery in the direction of sight, and then bends and extends toward the room side. The projection dimensions of the engagement leg 16d and the fixed leg 16e from the attachment base plate 16a are approximately the same as each other, and are set to be larger than the projection dimension of the inner overlapping piece 15j from the inner base wall 15a. The projection dimension (adjustment gap) L1 of the engagement leg 16d and the fixed leg 16e is set to be approximately the same as the gap (adjustment gap) d1 secured between the projection surface on the inner periphery of the inner base wall 15a in the upper frame 10A and the projection surface on the outer periphery of the part of the vertical frame 23 of the shoji screen 20 located on the room side.The vertical inner panel clamping plate portion 16b extends from the edge of the attachment base plate portion 16a on the interior side toward the inner periphery. The projection dimension of the vertical inner panel clamping plate portion 16b from the attachment base plate portion 16a is approximately the same as the panel clamping portion 12i of the pressing edge 12g. The support plate portion 16c extends from the edge of the vertical inner panel clamping plate portion 16b on the interior side toward the interior of the room in the forward direction. The extending edge of the support plate portion 16c is provided with an engagement portion 16g that can engage with the seal mounting portions 14e, 15e. This attachment 16 is attached to the opposing portions of each of the first vertical frames 14, 15 by engaging the extended edge portion of the engagement leg portion 16d with the attachment hooks 14d, 15d of the first vertical frames 14, 15, engaging the engagement portion 16g of the support plate portion 16c with the seal mounting portions 14e, 15e of the first vertical frames 14, 15, and further screwing a fixing screw 16h into the extended edge portion of the fixing leg portion 16e through the outer base wall portion 14a and the inner base wall portion 15a.

[0022] The lower edge of the panel P1 is inserted between the lower inner panel sandwiching wall 13c and the lower outer panel sandwiching wall 13d of the first lower frame 13 into the lower frame 10B to which the attachment 16 is attached, and then the first fixed window M12 is formed by attaching the battens 12g to the attachments 16, 16 of the first transom 12 and the first vertical frames 14, 15. The first fixed window M12 is also formed by attaching the battens 12g to the attachments 16, 16 of the first transom 12, the first lower frame 13, and the first vertical frames 14, 15, which abut against the surface of the panel P1, with the seal member S2 interposed therebetween. In this first fixed window M12, the attachment 16 and the battens 12g supporting the panel P1 do not have their edges located on the inner periphery side exposed beyond the inner frame inner sight wall 15c of the first inner vertical frame 15 or the outer frame inner sight wall 14c of the first outer vertical frame 14 when viewed from the inside of the room, which is advantageous in terms of appearance quality.

[0023] As described above, the gap d1 secured between the screen 20 and the first inner vertical frame 15 in the upper frame body 10A and the gap L1 secured between the attachment base plate 16a and the first inner vertical frame 15 in the lower frame body 10B are substantially the same. Therefore, the gap d1 secured between the first inner vertical frame 15 and the vertical frame 23 of the screen 20 in the upper frame body 10A and the gap L1 secured between the first inner vertical frame 15 and the attachment base plate 16a of the attachment 16 in the lower frame body 10B extend on the same straight line with the first transom 12 in between. In other words, different window types are arranged side by side in the upper frame body 10A and the lower frame body 10B, but the first vertical frames 14, 15 on the left and right each extend on the same straight line, and the vertical frames 23 and ridges 25 supporting the edges of the panel P1 and the ridges 12g of the attachment 16 extend on the same straight line with the same visible dimensions, and further, the gap d1 between the first inner vertical frame 15 and the vertical frame 23 and the gap L1 between the first inner vertical frame 15 and the attachment 16 also extend on the same straight line with the same visible dimensions, which is advantageous in terms of appearance quality when viewed from outside the room.

[0024] (Second stage window W2) The second upper frame 41 has an upper base wall 41a, an upper inner sight wall 41b, and an upper inner panel clamping wall 41c, and is configured so that the dimensions along the projection direction are approximately the same as those of the first upper frame 11. The upper base wall 41a extends approximately horizontally along the projection direction. An upper groove forming wall 41d is provided on the edge located on the outside of the room on the upper surface of the upper base wall 41a. The upper groove forming wall 41d extends upward from the upper base wall 41a in the projection direction, then extends toward the outside of the room in the projection direction, and further extends upward in the projection direction to form a gap groove 41e that opens to the outside above the upper base wall 41a. A batten 12g is attached to the portion of the projection surface below the upper base wall 41a that is the outside of the room. The push edge 12g, like that provided on the first upper frame 11, has an attachment portion 12h and a panel clamping portion 12i, and the panel clamping portion 12i extends downward in the find direction from the projected surface that is the inner periphery of the upper base wall portion 41a. The upper inner find wall portion 41b extends in the find direction from the edge portion located on the indoor side of the upper base wall portion 41a in the vertical direction. The upper inner panel clamping wall portion 41c extends in the find direction from a portion that is slightly outside the room from the center on the projected surface that is the lower side of the upper base wall portion 41a in the find direction downward. Between the extended edge portion of the upper inner panel clamping wall portion 41c to the lower edge portion of the upper inner find wall portion 41b, an upper hollow portion 41g is formed by the upper see-through wall portion 41f. The projection dimension of the upper inner panel clamping wall 41c from the upper base wall 41a is approximately the same as the panel clamping portion 12i of the ridge 12g. Although not shown in the figure, the second upper frame 41 is configured such that when the upper inner sight walls 11e, 41b are matched with the first upper frame 11, the upper base wall 41a is positioned at approximately the same height as the upper frame 21 of the first-stage window W1, and the portion of the upper groove-forming wall 41d extending in the sight direction is positioned at approximately the same height as the upper panel cover wall 11b of the first upper frame 11.

[0025] The second transom 42 has a middle base 42a, a middle-upper panel clamping wall 42b, and a middle-lower panel cover wall 42c. The middle base 42a is an irregular hollow shape. That is, the middle base 42a has a part facing the room, an upper part, and a lower part each extending on a flat surface, while the center part of the part facing the outside of the room is hat-shaped so that it protrudes toward the outside, and has recesses 42d, 42e at the upper corner edge and the lower corner edge on the outside of the room. The middle-upper panel clamping wall 42b extends from the upper part of the part protruding toward the outside of the middle base 42a in the projection direction almost horizontally toward the outside, and then extends upward in the sight direction. The dimension of the middle-upper panel clamping wall 42b along the sight direction is almost the same as the dimension of the sight surface of the lower frame 22 facing the outside of the shoji 20 of the first-stage window W1. The upper edge of the middle-upper panel clamping wall 42b is at approximately the same position as the upper surface of the middle base 42a. The middle-lower panel cover wall 42c extends approximately horizontally from the lower part of the part of the middle base 42a that protrudes to the outside of the room toward the outside of the room. Between the middle-lower panel cover wall 42c and the middle-upper panel clamping wall 42b, a dimension d3 is secured that is approximately the same as the gap d2 secured between the middle panel cover wall 12b of the first transom 12 that constitutes the upper frame 10A of the first stage window W1 and the projected surface that is the outer periphery side of the part located on the outside of the lower frame 22 of the shoji screen 20. A batten 12g is attached to the projected surface that is the lower part of the middle-lower panel cover wall 42c, on the part that is the outside of the room. The pressing edge 12g, like the one provided on the second upper frame 41, has an attachment portion 12h and a panel clamping portion 12i, and the panel clamping portion 12i extends downward in the viewing direction from the projected surface that is the inner periphery of the middle-lower panel cover wall portion 42c.

[0026] The second lower frame 43 has a lower base wall portion 13a, a lower inner sight wall portion 13b, a lower inner panel clamping wall portion 13c, and a lower outer panel clamping wall portion 13d, and has the same cross-sectional shape as the first lower frame 13.

[0027] The second vertical frames 44, 44 are symmetrical to each other on the left and right, and are configured so that the dimensions along the length are approximately the same as those of the first vertical frames 14, 15. In the illustrated example, each second vertical frame 44, 44 is configured with a vertical base wall portion 44a, a vertical inner sight wall portion 44b, and a vertical inner panel clamping plate portion 44c. The vertical base wall portion 44a, the vertical inner sight wall portion 44b, and the vertical inner panel clamping plate portion 44c correspond to the upper base wall portion 41a, the upper inner sight wall portion 41b, and the upper inner panel clamping wall portion 41c of the second upper frame 41, respectively. The vertical base wall portion 44a extends approximately vertically along the projection direction. A batten 12g is attached to the portion of the projection surface on the inner periphery side of the vertical base wall portion 44a that faces the outside of the room. The ridge 12g, like that provided on the second upper frame 41, has an attachment portion 12h and a panel clamping portion 12i, and the panel clamping portion 12i extends in the sight direction from the projected surface that is the inner periphery of the vertical base wall portion 44a toward the inner periphery. The vertical inner sight wall portion 44b extends in the sight direction from the edge portion located on the interior side of the vertical base wall portion 44a toward the inner periphery. As is clear from the figure, the vertical inner sight wall portion 44b in this embodiment is configured to have a plate thickness larger than that of the vertical base wall portion 44a (almost three times as thick in the illustrated example). A vertical locking protrusion 44d is provided on the interior side of the extended edge of the vertical inner sight wall portion 44b. The vertical locking protrusion 44d is paired with the inner locking protrusion 15f of the first inner vertical frame 15, has an engagement recess 44e and an introduction inclined surface 44f on the inner peripheral side, and protrudes toward the inside of the room. The vertical inner panel clamping plate portion 44c extends in the sight direction from a portion corresponding to the lower inner panel clamping wall portion 13c on the inner peripheral side of the projection surface of the vertical base wall portion 44a toward the inner peripheral side. A vertical hollow portion 44h is formed by the vertical projection wall portion 44g between the extending edge portion of the vertical inner panel clamping plate portion 44c and the inner peripheral edge portion of the vertical inner sight wall portion 44b. The projection dimension of the vertical inner panel clamping plate portion 44c from the vertical base wall portion 44a is approximately the same as the panel clamping portion 12i of the push edge 12g.

[0028] In addition, the second vertical frame 44, 44 has a vertical engagement piece 44i and a vertical overlap piece 44j on the projection surface on the outer periphery side of the vertical base wall portion 44a. The vertical engagement piece 44i extends from the portion inside the room from the edge portion located on the outside of the vertical base wall portion 44a toward the outer periphery, then bends and extends in the projection direction toward the outside of the room, forming a gap between the vertical base wall portion 44a and the inner engagement piece 15i of the first inner vertical frame 15. The vertical overlap piece 44j protrudes in the projection direction toward the outer periphery from the edge portion located on the inside of the vertical base wall portion 44a, and is provided so that when the vertical engagement piece 44i is engaged with the inner engagement piece 15i, it can be overlapped with the inner overlap piece 15j of the first inner vertical frame 15 from the inside of the room. The thickness of the vertical overlapping piece 44j is almost the same as that of the vertical inner sight wall 44b, and when it is overlapped with the inner overlapping piece 15j from the inside of the room, the sight surface of the vertical inner sight wall 44b facing the room and the sight surface of the inner frame inner sight wall 15c facing the room are set to be located on the same plane along the sight direction. In addition, at this time, the edge portion located on the outside of the vertical base wall 44a and the edge portion located on the outside of the inner base wall 15a are located on the same plane along the sight direction. The protruding dimension of the vertical overlapping piece 44j from the vertical base wall 44a is almost equal to the protruding dimension of the inner overlapping piece 15j from the inner base wall 15a. The extending edge portion of the vertical overlapping piece 44j is provided with a fitting protrusion (fitting portion) 44k on the part located on the outside of the room. The fitting protrusion 44k fits into the fitting groove portion 15k of the inner polymer piece 15j, and when fitted into the fitting groove portion 15k, the extending end face (defined surface) 44m of the vertical polymer piece 44j abuts against the expected surface on the outer periphery of the inner base wall portion 15a, and the surface of the vertical polymer piece 44j facing outside the chamber and the surface of the inner polymer piece 15j facing inside the chamber abut against each other.

[0029] In the second-stage window W2 having the second upper frame 41, second interlining 42, second lower frame 43, and second vertical frames 44, 44 configured as described above, the upper frame body 10C is formed by the second upper frame 41, the second interlining 42, and the second vertical frames 44, 44, and the lower frame body 10D is formed by the second interlining 42, the second lower frame 43, and the second vertical frames 44, 44, and a second upper FIX window M21 and a second lower FIX window M22 are formed by arranging panels P2, P3 having the same external dimensions in each frame body 10C, 10D. That is, in the upper frame body 10C, the lower edge of the panel P2 is set between the recessed portion 42d provided at the upper corner edge of the second transom 42 and the middle upper panel sandwiching wall portion 42b, and then the second upper frame 41 and the second vertical frame 44, 44 are fitted with the pressing edge 12g, respectively, to form the second upper FIX window M21. The second upper frame 41, the second transom 42, and the second vertical frame 44, 44 have the sealing member S2 interposed therein at their portions that abut against the surface of the panel P2. Similarly, in the lower frame body 10D, the lower edge of the panel P3 is set between the lower inner panel sandwiching wall portion 13c and the lower outer panel sandwiching wall portion 13d of the second lower frame 43, and then the pressing edge 12g is fitted to the second transom 42 and the second vertical frame 44, 44, respectively, to form the second lower FIX window M22. A seal member S2 is interposed in the portions of the second transom 42, the second lower frame 43, and the second vertical frames 44, 44 that come into contact with the surface of the panel P2. The position of the second transom 42 is set so that the upper surface of the middle / lower panel cover wall portion 42c coincides with the upper surface of the middle panel cover wall portion 12b in the first transom 12.

[0030] (Furniture configuration) To connect the first and second window sections W1 and W2 to the left and right, first, the inner engagement piece 15i on the first inner vertical frame 15 is engaged with the vertical engagement piece 44i on the second vertical frame 44, and then, as shown in Fig. 8, the inner overlap piece 15j on the first inner vertical frame 15 is overlapped with the vertical overlap piece 44j on the second vertical frame 44 from the inside of the room, and the fitting protrusion 44k is fitted into the fitting groove 15k. When the fitting protrusion 44k is fitted into the fitting groove 15k, the extending end surface 44m of the vertical overlap piece 44j is maintained in contact with the expected surface on the outer periphery side of the inner base wall portion 15a. That is, on the outside of the room, the engagement of the inner engagement piece 15i and the vertical engagement piece 44i restricts the movement of the first inner vertical frame 15 and the second vertical frame 44 in the direction away from each other, and on the inside of the room, the engagement of the engagement protrusion 44k and the engagement groove portion 15k restricts the movement of the first inner vertical frame 15 and the second vertical frame 44 in the direction away from each other. In addition, the extended edge portion of the inner engagement piece 15i abuts against the vertical base wall portion 44a, and the extended end face 44m of the vertical overlapping piece 44j abuts against the inner base wall portion 15a, so that the mutual distance between the first inner vertical frame 15 and the second vertical frame 44 is accurately determined. Therefore, from this state, as shown in Figures 6 and 7, if the screw member B1 is screwed into the inner overlapping piece 15j via the vertical overlapping piece 44j, the first and second step windows W1 and W2 can be connected to each other with the dimensions along the viewing direction accurately determined. Moreover, this fitting connects the first and second window sections W1 and W2 without the need for vertical frame members or mullion members, making it possible to prevent increases in manufacturing costs and external dimensions. Furthermore, the first inner vertical frame 15 and the second vertical frame 44 exposed to the interior side are fitted with a cover member C1 along their longitudinal lengths via the inner locking protrusions 15f and the vertical locking protrusions 44d provided on each of them, preventing the connection parts and screw members B1 from being exposed, which is also preferable in terms of design.

[0031] Between the first and second window stages W1 and W2, which are connected to each other, a groove-shaped recess 2 that opens toward the outside is formed in the area surrounded by the inner base wall portion 15a, the inner engagement piece 15i, and the vertical base wall portion 44a. Therefore, by filling this recess 2 with a sealant S4, it is possible to prevent water and air from passing between the first and second window stages W1 and W2, which is advantageous in terms of watertightness and airtightness.

[0032] Moreover, the gap d4 secured between the first upper frame 11 and the upper frame 21 of the shoji screen 20 in the first step window W1 and the gap groove portion 41e formed by the upper groove forming wall portion 41d of the second upper frame 41 in the second step window W2 have the same visible dimension and extend in the left-right direction at the same height position. Similarly, the gap d2 secured between the middle panel cover wall portion 12b of the first transom 12 and the lower frame 22 of the shoji screen 20 in the first step window W1 and the gap d3 between the middle lower panel cover wall portion 42c of the second transom 42 and the middle upper panel clamping wall portion 42b in the second step window W2 have the same visible dimension and extend in the left-right direction at the same height position. Therefore, in the two adjacent step windows W1 and W2, the gaps extending in the left-right direction are also continuous, which is advantageous in terms of appearance quality when viewed from the outside of the room.

[0033] Furthermore, the dimensions of the gaps provided on both sides of the first inner vertical frame 15 are not the same for the first and second window sections W1 and W2. However, by connecting the first window section W1 to both sides of the second window section W2 symmetrically, the left and right sides are symmetrical with the second window section W2 at the center. This results in a favorable appearance quality of the fixture when viewed from the outside.

[0034] In the above-described embodiment, the protruding dimension of the inner engagement piece 15i from the first inner vertical frame 15 is configured to be larger than the protruding dimension of the vertical engagement piece 44i from the second vertical frame 44, but it may also be configured so that the protruding dimension of the vertical engagement piece 44i from the second vertical frame 44 is larger than the protruding dimension of the inner engagement piece 15i from the first inner vertical frame 15.

[0035] Further, in the above-described embodiment, an example in which a plurality of step windows W1, W2 are connected to the left and right has been given, but the connecting frame body does not have to be a step window.

[0036] (Variation 1) In the above-mentioned embodiment, a continuous window of a vertical sliding window M11 and a fixed window and a continuous window of a fixed window and a fixed window are exemplified, but the window type of the frame body connected to the left and right is not limited to these. For example, in the modified example 1 shown in FIG. 9, a continuous window of a vertical sliding window M11 and a vertical sliding window M11 is shown. The frame body of the vertical sliding window M11 shown on the left side of the figure (hereinafter, referred to as the first frame body 10E when distinguishing) has the same configuration as the frame body 10A above the first stage window W1 shown in the embodiment. Therefore, the first frame body 10E is given the same reference numeral as in the embodiment, and detailed description is omitted. On the other hand, the frame body of the vertical sliding window M11 shown on the right side of the figure (hereinafter, referred to as the second frame body 10F when distinguishing) differs from the first frame body 10E only in the configuration of the vertical frame adjacent to the first frame body 10E.

[0037] That is, the vertical frame (frame material) 50 of the second frame body 10F has a vertical base wall portion 50a, a vertical door stop wall portion 50b, and a vertical inner sight wall portion 50c. The vertical base wall portion 50a extends almost vertically along the projection direction. The vertical door stop wall portion 50b extends from the projection surface that is the inner periphery side of the vertical base wall portion 50a toward the inner periphery side. A seal member S1 is attached to the projection surface facing the outside of the room at the extended edge of the vertical door stop wall portion 50b via a seal mounting portion 50d. The vertical inner sight wall portion 50c extends in the projection direction from the edge portion located on the indoor side of the vertical base wall portion 50a toward the inner periphery side. The protruding dimension of the vertical inner sight wall portion 50c toward the inner periphery side is almost equal to the protruding dimension of the vertical door stop wall portion 50b. The plate thickness of the vertical inner sight wall 50c is configured to be larger than that of the vertical base wall 50a. A vertical locking protrusion 50e is provided on the interior side of the extended edge of the vertical inner sight wall 50c. The vertical locking protrusion 50e has an engagement recess 50f and an introduction inclined surface 50g on the inner peripheral side, and protrudes toward the interior side of the vehicle.

[0038] In addition, the vertical frame 50 has a vertical engagement piece 50h and a vertical overlap piece 50i on the projection surface on the outer periphery of the vertical base wall portion 50a. The vertical engagement piece 50h extends from the portion inside the room from the edge portion located on the outside of the vertical base wall portion 50a toward the outer periphery, then bends and extends in the projection direction toward the outside of the room, forming a gap between the vertical base wall portion 50a and the inner engagement piece 15i of the first inner vertical frame 15. The vertical overlap piece 50i protrudes in the projection direction toward the outer periphery from the edge portion located on the inside of the vertical base wall portion 50a, and is provided so that when the vertical engagement piece 50h is engaged with the inner engagement piece 15i, it can be overlapped with the inner overlap piece 15j of the first inner vertical frame 15 from the inside of the room. The thickness of the vertical overlapping piece 50i is almost the same as that of the vertical inner sight wall 50c, and when it is overlapped with the inner overlapping piece 15j from the inside of the room, the sight surface of the vertical inner sight wall 50c facing the room and the sight surface of the inner frame inner sight wall 15c facing the room are set to be located on the same plane along the sight direction. In addition, at this time, the edge portion located on the outside of the vertical base wall portion 50a and the edge portion located on the outside of the room of the inner base wall portion 15a of the first inner vertical frame 15 are located on the same plane along the sight direction. The protruding dimension of the vertical overlapping piece 50i from the vertical base wall portion 50a is almost equal to the protruding dimension of the inner overlapping piece 15j from the inner base wall portion 15a. The extending edge portion of the vertical overlapping piece 50i is provided with a fitting protrusion 50j on the part located on the outside of the room. The fitting protrusion 50j fits into the fitting groove portion 15k of the inner polymer piece 15j, and when fitted into the fitting groove portion 15k, the extended end face (specified surface) of the vertical polymer piece 50i abuts against the expected surface on the outer periphery of the inner base wall portion 15a, and the surface of the vertical polymer piece 50i facing outside the chamber and the surface of the inner polymer piece 15j facing inside the chamber abut against each other.

[0039] As is clear from the figure, in the vertical frame 50, the inner peripheral edge (first inner peripheral edge) 25a of the batten 25 that supports the edge of the surface of the panel 24 facing the outside, and the inner peripheral edge (second inner peripheral edge) 23b of the vertical frame 23 that supports the edge of the surface of the panel 24 facing the inside, are both located on the same vertical plane along the projection direction with respect to the edge (frame edge) 50k located on the innermost side of the vertical inner visible wall 50c. Therefore, when viewed from inside the room, the vertical frame 23 and batten 25 of the shoji screen 20 are not exposed to the inner peripheral side beyond the vertical frame 50, which is advantageous in terms of appearance quality.

[0040] In order to connect the left and right frame bodies 10E, 10F in this modified example 1, first, the inner engagement piece 15i provided on the first inner vertical frame 15 is engaged with the vertical engagement piece 50h provided on the vertical frame 50, and the inner overlap piece 15j provided on the first inner vertical frame 15 is overlapped from the room side of the vertical overlap piece 50i provided on the vertical frame 50, and the fitting protrusion 50j is fitted into the fitting groove portion 15k. In the state where the fitting protrusion 50j is fitted into the fitting groove portion 15k, the extending end face of the vertical overlap piece 50i is maintained in contact with the expected surface on the outer periphery side of the inner base wall portion 15a, and the movement in the direction away from each other is restricted, and the mutual distance between the first inner vertical frame 15 and the vertical frame 50 is accurately determined. Therefore, if the screw member B1 is screwed into the inner overlapping piece 15j through the vertical overlapping piece 50i in this state, the two frame bodies 10E, 10F can be connected to each other with the dimensions along the viewing direction accurately defined. In this modified fitting, the left and right frame bodies 10E, 10F are connected without the need for vertical frame members or upright members, so that it is possible to suppress the increase in manufacturing costs and external dimensions. Furthermore, the first inner vertical frame 15 and the vertical frame 50 exposed to the interior side can be fitted with a cover member C1 along the length via the inner locking protrusion 15f and the vertical locking protrusion 50e provided on each of them, thereby preventing the connection part and the screw member B1 from being exposed, which is also preferable in terms of design.

[0041] Between the mutually connected frame bodies 10E, 10F, a groove-shaped recess 2 that opens toward the outside of the room is formed in the area surrounded by the inner base wall portion 15a, the inner engagement piece 15i, and the vertical base wall portion 50a. Therefore, by filling this recess 2 with a sealant S4, it is possible to prevent the flow of water and air between the indoors and outdoors through the space between the frame bodies 10E, 10F, which is advantageous in terms of watertightness and airtightness. In addition, when viewed from the outside of the room, the left and right sides are symmetrical, which is advantageous in terms of appearance quality.

[0042] In this modified example 1, the projection dimension of the inner engagement piece 15i, the projection dimension of the inner overlapping piece 15j, the projection dimension of the vertical overlapping piece 50i, and the dimension of the gap secured between each frame body 10E, 10F and each shoji 20 may be appropriately adjusted. For example, if the dimension d5 from the edge located on the innermost periphery of the vertical frame 23 and the batten 25 in the first frame body 10E to the edge located on the innermost periphery of the vertical frame 23 and the batten 25 in the second frame body 10F is set equal to the dimension d6 from the edge located on the innermost periphery of the vertical frame 23 and the batten 25 in the first stage window W1 of the embodiment shown in (b) to the edge located on the innermost periphery of the second vertical frame 44 and the batten 12g in the second stage window W2, the cover member C1 shown in the embodiment can be applied as it is. Furthermore, it becomes possible to arrange the connecting part of the vertical frame 50 exposed when viewed from the outside of the room on the same straight line with the same visible dimension, and there is no risk of impairing the appearance quality.

[0043] (Variation 2) In the above-mentioned embodiment, the first inner vertical frame 15 is exemplified as an inner base wall portion 15a having a flat plate shape, while the second vertical frame 44 is exemplified as an inner hollow portion 44h, but the present invention is not limited thereto. For example, in the modified example 2 shown in FIG. 10, a hollow portion is applied as the first inner vertical frame (frame material) 60, and a flat portion is applied as the second vertical frame (frame material) 61. That is, in the first inner vertical frame 60 of the modified example 2, compared with that of the embodiment, the inner engagement piece 60i and the inner overlapping piece 60j are each extended, and an inner projection wall portion 60m along the projection direction is provided between the extended inner engagement piece 60i and the inner overlapping piece 60j, thereby forming a hollow portion 60n between the inner base wall portion 15a. The protruding dimensions of the inner engagement piece 60i and the inner overlapping piece 60j from the inner projection wall portion 60m are the same as the protruding dimensions from the inner base wall portion 15a in the embodiment. On the other hand, in the second vertical frame 61 of the second modified example, the vertical projection wall portion 44g is omitted to open the gap between the vertical inner panel clamping plate portion 44c and the vertical inner projection wall portion 44b. In the second modified example shown in FIG. 10, the same components as those in the embodiment are denoted by the same reference numerals as those in the embodiment.

[0044] In this modified example 2, as in the embodiment, the inner engagement piece 60i provided on the first inner vertical frame 60 is engaged with the vertical engagement piece 44i provided on the second vertical frame 61, and the inner overlap piece 60j provided on the first inner vertical frame 60 is overlapped with the vertical overlap piece 44j provided on the second vertical frame 61 from the room side, and in this state, a screw member (not shown) is screwed into the inner overlap piece 60j via the vertical overlap piece 44j, making it possible to connect them together with the dimensions along the viewing direction accurately defined. In modified example 2, the screw member and cover member are omitted, but it goes without saying that they are provided as in the embodiment.

[0045] Between the first inner vertical frame 60 and the second vertical frame 61, which are connected to each other, a groove-shaped recess 3 that opens toward the outside is formed in the area surrounded by the inner base wall portion 15a, the inner engagement piece 60i, and the vertical base wall portion 44a. Therefore, by filling this recess 3 with the sealant S4, it is possible to prevent the flow of water and air between the inside and outside of the room through the space between the first inner vertical frame 60 and the second vertical frame 61, which is advantageous in terms of watertightness and airtightness.

[0046] (Variation 3) In the above-mentioned embodiment, the first inner vertical frame 15 is exemplified as an inner base wall portion 15a having a flat plate shape, and the second vertical frame 44 is exemplified as an inner base wall portion 44a having a flat plate shape, but the present invention is not limited thereto. For example, in the modified example 3 shown in FIG. 11, in the first inner vertical frame 60 shown in the modified example 2, a bridge material 63 made of a resin material is interposed in the middle part between the inner base wall portion 15a and the inner projection wall portion 60m. Similarly, in the second vertical frame (frame material) 64, the part of the vertical base wall portion 44a that is on the outdoor side of the vertical inner panel clamping plate portion 44c is configured to be hollow, and a bridge material 65 made of a resin material is interposed in the middle part. According to this modified example 3, it is possible to achieve the same action and effect as the embodiment, and the bridge materials 63, 65 can block the heat transfer between the indoors and outdoors through the first inner vertical frame 60 and the second vertical frame 64, which is advantageous in terms of heat insulation. In the third modification shown in Fig. 11, the same components as those in the embodiment are given the same reference numerals as those in the embodiment. The reference numeral 66 in Fig. 11 denotes a bridge material made of a resin material interposed between the part of the vertical frame 23 of the shoji screen 20 that faces the room interior and the part that faces the room exterior.

[0047] (Variation 4) In the above-described embodiment, the screen door 30 is provided on the indoor side of the vertical sliding window M11, but it is also possible to omit the screen door 30 and connect the left and right vertical frames as in Variation 4 shown in Fig. 12. In Variation 4, the same components as in the embodiment are given the same reference numerals. In Variation 4, the inner frame inner sight wall 15c is omitted and the inner door stop wall 15b is provided with an inner locking protrusion 15f, but the inner door stop wall 15b may be omitted and a seal mounting portion 15e may be provided on the inner peripheral edge to give the inner frame inner sight wall 15c a door stop function, and an inner seal member S1 may be attached thereto.

[0048] (Variation 5) In the above-mentioned embodiment, a continuous window in which the frame bodies arranged side by side are connected to each other is illustrated, but the present invention is not limited to this, and can be similarly applied to the frame bodies arranged side by side vertically, as in the modified example 5 shown in FIG. 13. That is, the fitting shown in the modified example 5 has an upper vertical sliding window M11 and a lower FIX window, similar to the first-stage window W1 of the embodiment, and the lower frame (frame material) 71 of the upper frame body (hereinafter, when distinguished, referred to as the upper frame body 10A) and the upper frame (frame material) 72 of the lower frame body (hereinafter, when distinguished, referred to as the lower frame body 10B) are connected to each other. Note that the fitting of the modified example 5 has the same configuration as the first-stage window W1 of the embodiment, except for the lower frame 71 of the upper frame body 10A and the upper frame 72 of the lower frame body 10B. Therefore, in the following, the lower frame 71 of the upper frame body 10A and the upper frame 72 of the lower frame body 10B will be mainly described, and the same reference numerals will be used to denote the same configuration as the embodiment, and the description will be omitted.

[0049] The lower frame 71 of the upper frame body 10A has a lower base wall portion 71a, a lower shoji cover wall portion 71b, a lower door stop wall portion 71c, a lower screen cover wall portion 71d, and a lower inner sight wall portion 71e. The lower base wall portion 71a extends almost horizontally along the projection direction. The lower shoji cover wall portion 71b protrudes downward from the edge portion of the lower base wall portion 71a that is the outside of the room, and then extends in the projection direction toward the outside of the room. The lower door stop wall portion 71c extends upward in the projection direction from the edge portion located on the inside of the room of the lower base wall portion 71a. An inner seal member S1 is attached to the part of the extended edge portion of the lower door stop wall portion 71c that faces the outside of the room via a seal attachment portion 71f. The lower screen cover wall portion 71d protrudes downward from the edge portion located on the inside of the room of the lower base wall portion 71a, and then extends in the projection direction toward the room. The lower inner sight wall 71e extends upward in the sight direction from the edge of the lower screen cover wall 71d located on the interior side of the room. As is clear from the figure, the lower inner sight wall 71e of the modified example 5 is configured to have a thickness greater than that of the lower base wall 71a. A lower locking protrusion 71g is provided on the interior side of the extending edge of the lower inner sight wall 71e. The lower locking protrusion 71g has an engagement recess 71h and an introduction inclined surface 71i on the upper part, and protrudes toward the interior side of the room.

[0050] The lower frame 71 is provided with a lower engagement piece 71j on its projected surface below the lower shoji cover wall portion 71b, and a lower overlapping piece 71k on its projected surface below the lower screen cover wall portion 71d. The lower engagement piece 71j extends downward from a portion that is closer to the interior side than the edge portion located on the exterior side of the lower shoji cover wall portion 71b, then bends and extends in the projected direction toward the interior side of the room. The lower overlapping piece 71k extends downward from a portion that is closer to the exterior side than the edge portion located on the interior side of the lower screen cover wall portion 71d. An engagement groove portion (engagement portion) 71m is provided in the portion of the lower overlapping piece 71k that is located at the connection portion with the lower screen cover wall portion 71d on its projected surface facing the interior of the room.

[0051] The upper frame 72 of the lower frame body 10B has an upper base wall portion 72a, an upper panel cover wall portion 72b, an upper inner projection wall portion 72c, an upper inner panel clamping wall portion 72d, and an upper inner sight wall portion 72e. The upper base wall portion 72a extends almost horizontally along the projection direction. The upper panel cover wall portion 72b extends in the projection direction toward the outside of the room after protruding upward from the edge portion located on the outside of the upper base wall portion 72a. A joist 12g is attached to the portion of the projection surface that is the lower side of the upper panel cover wall portion 72b that is the outside of the room. The joist 12g has an attachment portion 12h and a panel clamping portion 12i, as in the embodiment. The upper inner projection wall portion 72c extends in the projection direction toward the room after protruding upward from the edge portion located on the inside of the upper base wall portion 72a. The upper inner panel clamping wall 72d extends downward in the find direction from the lower projection surface of the upper base wall 72a. The projection dimension of the upper inner panel clamping wall 72d from the upper base wall 72a is approximately the same as the panel clamping portion 12i of the ridge 12g. The upper inner find wall 72e extends downward in the find direction from the edge portion located on the interior side of the upper inner find wall 72c. The plate thickness of the upper inner find wall 72e is approximately the same as that of the lower inner find wall 71e. An upper locking protrusion 72f is provided on the interior side of the extended edge portion of the upper inner find wall 72e. The upper locking protrusion 72f is paired with the lower locking protrusion 71g of the lower frame 71, has an engagement recess 72g and an introduction inclined surface 72h on the lower portion, and protrudes toward the interior side. An upper hollow portion 72j is defined by an upper front wall portion 72i between the extended edge portion of the upper inner front wall portion 72e and the lower edge portion of the upper inner panel sandwiching wall portion 72d.

[0052] In addition, the upper frame 72 is provided with an upper engagement piece 72k on the projection surface above the upper panel cover wall portion 72b, and an upper overlapping piece 72m is provided on the edge portion on the interior side of the upper inner projection wall portion 72c. The upper engagement piece 72k extends upward from a portion that is on the interior side of the interior of the upper panel cover wall portion 72b, then bends and extends in the projection direction toward the exterior of the room, forming a gap between the upper panel cover wall portion 72b and the upper panel cover wall portion 72b into which the lower engagement piece 71j of the lower frame 71 can be fitted. The upper overlapping piece 72m protrudes upward in the projection direction from the edge portion on the interior side of the upper inner projection wall portion 72c, and is provided so that when the upper engagement piece 72k is fitted into the lower engagement piece 71j, it can be overlapped with the lower overlapping piece 71k of the lower frame 71 from the interior side. The thickness of the upper overlapping piece 72m is approximately the same as that of the upper inner sight wall 72e, and is set so that when it is placed over the lower overlapping piece 71k from the inside of the room, the sight surface of the upper inner sight wall 72e facing the room and the sight surface of the lower inner sight wall 71e facing the room are located on the same plane along the sight direction. Also, at this time, the edge portion located on the outside of the lower shoji cover wall 71b and the edge portion located on the outside of the upper panel cover wall 72b are located on the same plane along the sight direction. The extending edge portion of the upper overlapping piece 72m is provided with a fitting protrusion (fitting portion) 72n on the part located on the outside of the room. The fitting protrusion 72n fits into the fitting groove 71m of the lower overlapping piece 71k, and when fitted into the fitting groove 71m, the extended end face (defined surface) 72p of the upper overlapping piece 72m abuts against the expected surface of the lower screen cover wall portion 71d, and the surface of the upper overlapping piece 72m facing outside the room and the surface of the lower overlapping piece 71k facing inside the room abut against each other.

[0053] To connect the upper and lower frame bodies 10A, 10B in this modified example 5, first, the lower engagement piece 71j on the lower frame 71 is engaged with the upper engagement piece 72k on the upper frame 72, and the upper overlapping piece 72m on the upper frame 72 is overlapped from the inside of the room with the lower overlapping piece 71k on the lower frame 71, and the fitting protrusion 72n is fitted into the fitting groove 71m. With the fitting protrusion 72n fitted into the fitting groove 71m, the extending end surface 72p of the upper overlapping piece 72m is maintained in contact with the expected surface below the lower screen cover wall portion 71d, restricting movement away from each other and accurately defining the distance between the lower frame 71 and the upper frame 72. Therefore, if the screw member B1 is screwed into the lower overlapping piece 71k via the upper overlapping piece 72m in this state, it becomes possible to connect the two frames 10A, 10B to each other with the dimensions along the viewing direction accurately defined. By attaching the cover member C2 along the longitudinal direction via the lower locking protrusions 71g and upper locking protrusions 72f provided on the lower frame 71 and upper frame 72 exposed to the indoor side, respectively, it is possible to prevent the connecting parts and the screw member B1 from being exposed, which is also preferable in terms of design.

[0054] Between the mutually connected frame bodies 10A, 10B, a groove-like recess 4 that opens toward the outside is formed in the area surrounded by the lower shoji cover wall portion 71b, the lower engagement piece 71j, and the upper panel cover wall portion 72b. Therefore, by filling this recess 4 with a sealant S4, it is possible to prevent the flow of water and air between the upper frame body 10A and the lower frame body 10B, which is advantageous in terms of watertightness and airtightness.

[0055] In the above-mentioned embodiment, the first inner peripheral edge portion located on the inner periphery of the battens and vertical frames that support the edge portion of the surface of the panel facing the outside, and the second inner peripheral edge portion located on the inner periphery of the battens and vertical frames that support the edge portion of the surface of the panel facing the inside of the room, are configured to be located on the same side as the frame edge portion located on the inner periphery of the visible surface of the vertical frame that faces the inside of the room in the projection direction, or on the outer side of the frame edge portion, but this is not necessarily limited to this. In particular, for sliding windows, it is preferable to configure the frame material to protrude from the visible surface of the frame body to the inside of the room from the viewpoint of opening and closing operability.

[0056] As described above, the fittings of the present invention are fittings constructed by connecting frame bodies with panels arranged inside them in a side-by-side state, and are characterized in that, on at least one of the frame bodies, the first inner periphery edge portion located on the inner periphery of the shaped member supporting the edge portion of the surface of the panel facing the outside of the room and the second inner periphery edge portion located on the inner periphery of the shaped member supporting the edge portion of the surface of the panel facing the inside of the room are each positioned at the same position in the projection direction as the frame material edge portion located on the inner periphery of the visible surface of the frame material facing the inside of the room, or are positioned more outer than the frame material edge portion, and the adjacent frame members of the frame body are provided with engaging pieces that extend in the projection direction from the opposing visible surfaces and then bend and extend in the projection direction, and the adjacent frame members are prevented from moving away from each other by engaging the engaging piece provided on one frame member between the engaging piece and the visible surface with the engaging piece provided on the other frame member. According to this invention, by engaging the engagement pieces along the projection direction, it is possible to prevent the adjacent frame bodies from moving away from each other, so it is possible to connect the frame bodies arranged side by side without the need for vertical beams or uprights, and it is possible to prevent the increase in manufacturing costs and external dimensions. Note that the frame bodies arranged side by side do not have to be arranged side by side, and the invention can be applied to cases where they are arranged side by side vertically.

[0057] The present invention is also characterized in that, in the above-mentioned building fixture, the engaging piece is provided on a portion that is closer to the inside of the room than the edge portion of the frame body that is located on the outside of the room, and a recess for filling with sealing material is provided in the portion of the engaging piece facing the outside of the room between the one frame material and the other frame material. According to this invention, by filling the recesses with a sealing material, it is possible to prevent the passage of water and air between the indoors and outdoors through between the frame bodies, which is advantageous in terms of watertightness and airtightness.

[0058] The present invention is also characterized in that, in the above-mentioned building fixture, the one frame material and the other frame material each have a flat base wall portion extending along the projection direction, and are connected to each other with their projection surfaces facing each other on the outer periphery of the base wall portions. According to this invention, the shape of the outer peripheral surface of the frame can be simplified, which has the advantage that the operation of engaging the engaging pieces can be made easier.

[0059] The present invention is also characterized in that, in the above-mentioned building fixture, an adjustment gap is secured on one side of the frame body between a projected surface that is on the inner periphery of the base wall portion of the frame material and a projected surface that is on the outer periphery of the projected wall portion that faces the outer periphery of the panel in the frame material supporting the panel. According to this invention, when the frame bodies are arranged side by side above and below, the positions of the adjustment gaps can be made to coincide, which is preferable in terms of appearance quality.

[0060] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the engaging piece is provided on a portion that is closer to the interior side than the edge portion located on the exterior side of the frame body, a recess for filling with sealing material is provided in the portion of the engaging piece facing the exterior between the one frame material and the other frame material, the dimension of the adjustment gap along the find direction is larger than the dimension of the recess along the find direction, and frame bodies having the adjustment gap are each connected to both sides of a single frame body via one of the frame materials. According to this invention, by providing frame bodies having recesses and adjustment gaps of different dimensions on both sides of a single frame body, it is possible to construct a fitting having an overall symmetrical shape, which is advantageous in terms of appearance quality.

[0061] The present invention is also characterized in that, in the above-mentioned building fixture, the one frame material and the other frame material are each provided with overlapping pieces that overlap each other in the front direction at a portion located on the inside of the room relative to the engaging piece, and at least one of the overlapping pieces is provided with a defined surface that abuts against the front surface of the frame material on which the other of the overlapping pieces is provided. According to this invention, it is possible to accurately determine the dimensions of the connected frame body by abutting the specified surface of the overlapping piece with the prospective surface of the frame material.

[0062] The present invention is also characterized in that, in the above-mentioned building fixture, the overlapping pieces are provided with an engaging portion, which engages when the defined surface abuts the projected surface of the frame material on which the other of the overlapping pieces is provided, thereby regulating the relative movement of the overlapping pieces along the projected direction. According to this invention, the relative movement is restricted by fitting the fitting portions of the overlapping pieces together, which has the advantage that the work of connecting the frame bodies can be simplified.

[0063] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the frame bodies are arranged side by side on the left and right and connected to each other via adjacent vertical frames. According to the present invention, a series of windows having the above-mentioned advantages can be constructed. [Explanation of symbols]
