Description

Technical Field

[0001] The present invention relates to a door and window, and more particularly to a door and window such as a horizontally connected window or a vertically connected window, which is formed by connecting a plurality of frames to each other. Background Art

[0002] Some of these doors and windows have vertical mullion members or middle mullion members interposed between frame bodies arranged side by side, and vertical frames of the respective frame bodies are connected to these vertical mullion members or middle mullion members (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent Laid-Open No. 7-54546 Summary of the invention

[0004] However, in these doors and windows, since the vertical mullion members or the middle mullion members are interposed between the vertical frames, there is a possibility that not only the manufacturing cost is increased but also the outer dimensions are increased.

[0005] In view of the above-mentioned actual situation, an object of the present invention is to provide a door and window capable of suppressing an increase in manufacturing cost and an increase in outer dimensions.

[0006] In order to achieve the above-mentioned purpose, the door and window of the present invention is constructed by connecting frames with panels arranged inside in a state of being arranged side by side with each other. In at least one of the frames, the first inner peripheral side edge portion of the profile supporting the edge portion of the surface facing the outdoor of the panel, and the second inner peripheral side edge portion of the profile supporting the edge portion of the surface facing the indoor of the panel, are respectively arranged at the following positions in the depth direction, that is, the position is the same as the frame material edge portion of the main viewing surface facing the indoor of the frame material, which is located on the inner peripheral side, or is closer to the outer peripheral side than the frame material edge portion. The frame materials adjacent to each other in the frame are respectively provided with locking pieces, which extend from the opposite depth surfaces in the direction of the main viewing surface, then bend and extend in the depth direction. The adjacent frame materials are prevented from moving in directions away from each other by locking the locking piece set on the other frame material between the locking piece set on the one frame material and the depth surface.

[0007] According to the present invention, by engaging the engaging pieces along the depth direction, adjacent frames can be prevented from moving in directions away from each other. Therefore, the frames arranged side by side can be connected to each other without the need for longitudinal or middle rail components, thereby suppressing the increase in manufacturing costs and external dimensions.

The protruding dimension of the middle inner panel clamping wall portion 12f from the middle panel cover wall portion 12b is substantially the same as that of the panel clamping portion 12i of the pressing edge 12g. Between the extending edge of the middle inner panel clamping wall portion 12f and the lower edge of the middle inner main viewing wall portion 12e, a horizontal bar hollow portion 12m is formed by the middle depth wall portion 12k.

[0057] The first lower frame 13 has a lower base wall portion 13a, a lower inner main viewing wall portion 13b, a lower inner panel clamping wall portion 13c, and a lower outer panel clamping wall portion 13d. The lower base wall portion 13a corresponds to the middle base wall portion 12a, the middle panel cover wall portion 12b, and the middle screen cover wall portion 12d of the first cross member 12. The lower inner main viewing wall portion 13b, the lower inner panel clamping wall portion 13c, and the lower outer panel clamping wall portion 13d correspond to the middle inner main viewing wall portion 12e, the middle inner panel clamping wall portion 12f, and the panel clamping portion 12i of the pressure edge 12g of the first cross member 12, respectively. The lower base wall portion 13a extends approximately horizontally along the depth direction. The lower inner main viewing wall portion 13b extends upward and downward along the main viewing surface direction from the edge of the lower base wall portion 13a located on the indoor side. The lower inner panel clamping wall portion 13c extends upward in the main viewing direction from a portion of the depth surface above the lower base wall portion 13a corresponding to the middle inner panel clamping wall portion 12f.

The lower outer panel clamping wall portion 13d extends upward in the main viewing direction from the edge of the lower base wall portion 13a located on the outdoor side. The protruding dimension of the lower outer panel clamping wall portion 13d from the lower base wall portion 13a is substantially the same as the protruding dimension of the lower inner panel clamping wall portion 13c.

[0058] The first longitudinal frame (hereinafter referred to as the first outer longitudinal frame 14 when distinction is needed) arranged on the outer peripheral side of the door and window and the first longitudinal frame (hereinafter referred to as the first inner longitudinal frame 15 when distinction is needed) connected to the second longitudinal frame 44 of the second longitudinal connecting window W2 are respectively arranged in a row between the longitudinal sliding window M11 of the first longitudinal connecting window W1 and the first fixed window M12.

[0059] The first outer longitudinal frame 14 has an outer base wall portion 14a, an outer door stop wall portion 14b, and an outer frame inner main viewing 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 main viewing wall portion 14c correspond to the upper door stop wall portion 11c and the upper inner main viewing wall portion 11e of the first upper frame 11, respectively. The outer base wall portion 14a extends approximately vertically along the depth direction. A strip hook 14d is provided at the edge of the outdoor side in the depth surface on the inner peripheral side of the outer base wall portion 14a. The strip hook 14d bends toward the indoor side after protruding toward the inner peripheral side. The outer door stop wall portion 14b extends toward the inner peripheral side from the portion corresponding to the upper door stop wall portion 11c of the first upper frame 11 in the depth surface on the inner peripheral side of the outer base wall portion 14a. The protruding dimension of the outer door stop wall portion 14b from the outer base wall portion 14a is set to be larger than the protruding dimension of the upper door stop wall portion 11c from the upper base wall portion 11a. In the approximately middle portion of the main viewing surface of the outer door stop wall portion 14b facing the outside, the inner sealing component S1 is installed via the sealing installation portion 14e only in the portion above the first cross member 12. The inner main viewing wall portion 14c of the outer frame extends from the edge of the outer base wall portion 14a located on the indoor side to the inner peripheral side and the outer peripheral side along the main viewing surface direction.

[0060] The first inner longitudinal frame 15 has an inner base wall 15a, an inner door stop wall 15b, and an inner frame inner main viewing wall 15c. The inner base wall 15a, the inner door stop wall 15b, and the inner frame inner main viewing wall 15c correspond to the outer base wall 14a, the outer door stop wall 14b, and the outer frame inner main viewing wall 14c of the first outer longitudinal frame 14, respectively. The inner base wall 15a extends substantially vertically along the depth direction. A strip hook 15d identical to the first outer longitudinal frame 14 is provided at the edge of the inner peripheral side of the depth surface of the inner base wall 15a on the outer side. The inner door stop wall 15b extends toward the inner peripheral side from a portion of the inner peripheral side of the depth surface of the inner base wall 15a corresponding to the outer door stop wall 14b of the first outer longitudinal frame 14. The protruding dimension of the inner door stop wall portion 15b from the inner base wall portion 15a is substantially equal to the protruding dimension of the upper door stop wall portion 11c from the upper base wall portion 11a. On the main viewing surface facing the outside of the extended edge of the inner door stop wall portion 15b, only the portion above the first crosspiece 12 is installed with the inner sealing component S1 via the sealing installation portion 15e. The inner frame inner main viewing wall portion 15c extends from the edge of the inner base wall portion 15a located on the indoor side to the inner peripheral side along the main viewing surface direction. The protruding dimension of the inner frame inner main viewing wall portion 15c to the inner peripheral side is substantially equal to the protruding dimension of the inner door stop wall portion 15b. As can be seen from the figure, the inner frame inner main viewing wall portion 15c of the present embodiment is configured to have a plate thickness greater than that of the outer frame inner main viewing wall portion 14c (almost 3 times in the example shown in the figure). The inner locking protrusion 15f is provided on the portion of the extended edge of the inner frame inner main viewing wall portion 15c located on the indoor side. The inner locking projection 15f has an engagement recess 15g and an introduction inclined surface 15h at the inner peripheral side portion, and projects toward the inner side of the room.

[0061] In addition, in the first inner longitudinal frame 15, an inner engaging piece 15i and an inner superimposing piece 15j are provided on the depth surface of the outer peripheral side of the inner base wall portion 15a. The inner engaging piece 15i extends from a portion of the inner base wall portion 15a that is closer to the indoor side than the edge portion located on the outdoor side to the outer peripheral side, then bends, and extends toward the indoor side along the depth direction. The inner superimposing piece 15j extends from a portion of the inner base wall portion 15a that is closer to the outdoor side than the edge portion located on the indoor side to the outer peripheral side. The protruding dimension of the inner superimposing piece 15j from the inner base wall portion 15a is substantially equal to the protruding dimension of the inner engaging piece 15i. A fitting groove portion (fitting portion) 15k is provided on the portion of the inner superimposing piece 15j that is located at the connection portion with the inner base wall portion 15a in the main viewing surface facing the indoor side.

[0062] In the first longitudinal connecting window W1 having the first upper frame 11, the first cross bar 12, the first lower frame 13, and the first vertical frames 14 and 15 constructed in the above manner, the upper frame 10A is composed of the first upper frame 11, the first cross bar 12, the first vertical frames 14 and 15, and the lower frame 10B is composed of the first cross bar 12, the first lower frame 13, the first vertical frames 14 and 15.

[0063] In the upper frame 10A, a link mechanism 1 called a slide brace is sandwiched between the upper base wall 11a of the first upper frame 11 and the upper frame 21 of the window sash 20, and between the middle base wall 12a of the first cross bar 12 and the lower frame 22 of the window sash 20, so as to form a longitudinal slide-out window M11 in a manner that can be opened to the outside. When the window sash 20 is arranged in a closed position, the depth surface of the inner peripheral side of the upper frame 10A and the depth surface of the outer peripheral side of the window sash 20 are ensured to have substantially equal gaps. Therefore, the inner sealing member S1 provided in each of the first upper frame 11, the first cross bar 12, and the first longitudinal frames 14 and 15 is in a state of being in contact with the main viewing surfaces of the upper frame 21, the lower frame 22, and the left and right longitudinal frames 23 and 23 facing the indoor room in a row. In addition, the upper sealing member 11g provided on the first upper frame 11 is sandwiched between the first upper frame 11 and the upper frame 21, and the side sealing members 23a, 23a provided on the longitudinal frames 23, 23 are sandwiched between the first longitudinal frames 14, 15 and the longitudinal frames 23, 23, respectively. Therefore, the water tightness and air tightness in the indoor and outdoor directions can be ensured. In addition, in the upper frame 10A, the part closer to the indoor side than the window sash 20 is stored between the outer door stop wall portion 14b of the first outer longitudinal frame 14 and the main visual wall portion 14c on the inner side of the outer frame. If the screen 30 is pulled out, the upper frame 10A can be covered by the mesh body 33 in the state of opening the window sash 20, so that ventilation between the indoor and outdoor can be achieved without causing foreign objects such as insects to enter the room.

[0064] In addition, it can be seen from the figure that in the first inner longitudinal frame 15, the inner peripheral edge portion (first inner peripheral edge portion) 25a of the edge portion of the press edge 25 of the surface facing the outdoor of the support panel 24, and the inner peripheral edge portion (second inner peripheral edge portion) 23b of the longitudinal frame 23 of the surface facing the indoor of the support panel 24 are both located on the same vertical plane along the depth direction relative to the innermost peripheral edge portion (frame material edge portion) 15m of the inner main visual wall portion 15c of the inner frame. Similarly, in the first outer longitudinal frame 14, the inner peripheral edge portion 25a of the press edge 25 of the surface facing the outdoor of the support panel 24, and the inner peripheral edge portion 23b of the longitudinal frame 23 of the surface facing the indoor of the support panel 24 are both located on the outer peripheral side relative to the innermost peripheral edge portion (frame material edge portion) 14f of the inner main visual wall portion 14c of the outer frame. Therefore, when viewed from the indoor side, the vertical side frames 23, 23 and the pressed edges 25, 25 of the window sash 20 do not protrude toward the inner peripheral side beyond the first vertical frames 14, 15, which is advantageous in terms of appearance quality.

[0065] On the other hand, in the frame 10B below, the first fixed window M12 is formed by installing the strips 16 on the first outer longitudinal frame 14 and the first inner longitudinal frame 15, and arranging the panel P1 between these strips 16 and the first cross member 12 and the first lower frame 13. The outer dimensions of the panel P1 are roughly the same as the panel P1 of the window sash 20 arranged in the frame 10A above. The strips 16 are symmetrical in shape and have a strip base plate portion 16a, a longitudinal inner panel clamping plate portion 16b, and a support plate portion 16c. The strip base plate portion 16a and the longitudinal inner panel clamping plate portion 16b correspond to the middle panel cover wall portion 12b and the middle inner panel clamping wall portion 12f of the first cross member 12, respectively. The strip base plate portion 16a extends roughly vertically along the depth direction. A pressing edge 12g is installed on the strip base plate portion 16a, and a snap-fit ​​foot portion 16d and a fixing foot portion 16e are provided. The edge pressing part 12g is the same as the edge pressing part provided on the first cross member 12, and has a mounting part 12h and a panel clamping part 12i, and is installed on the outdoor side of the depth surface of the inner peripheral side of the strip base plate part 16a. The engaging leg part 16d and the fixing leg part 16e extend from the depth surface of the outer peripheral side of the strip base plate part 16a to the outer peripheral side along the main viewing surface direction. The engaging leg part 16d extends from the outdoor side part to the outer periphery. At the extended edge of the engaging leg part 16d, an engaging claw part 16f capable of engaging with the strip hooks 14d and 15d of the first longitudinal frames 14 and 15 is provided in a manner bent toward the outdoor side. The fixing leg part 16e extends from the edge of the indoor side of the strip base plate part 16a to the outer peripheral side along the main viewing surface direction, and then bends and extends toward the indoor side. The protruding dimensions of the engaging legs 16d and the fixing legs 16e from the strip base plate 16a are substantially the same, and are set to be larger than the protruding dimensions of the inner superimposed piece 15j from the inner base wall 15a. In addition, the protruding dimensions (adjustment gap) L1 of the engaging legs 16d and the fixing legs 16e are set in a manner substantially the same as the following gap (adjustment gap) d1, that is, the gap (adjustment gap) d1 is the gap to be ensured between the depth surface of the inner peripheral side of the inner base wall 15a in the upper frame 10A and the depth surface of the outer peripheral side of the part of the longitudinal frame 23 of the window sash 20 located on the outdoor side. The longitudinal inner panel clamping plate portion 16b extends from the edge of the indoor side of the strip base plate portion 16a to the inner peripheral side. The protruding dimensions of the longitudinal inner panel clamping plate portion 16b from the strip base plate portion 16a are substantially the same as the panel clamping portion 12i of the press edge 12g. The support plate portion 16c extends from the inner peripheral edge of the vertical inner panel clamping plate portion 16b toward the interior of the room in the depth direction. An engaging portion 16g that can engage with the seal mounting portions 14e and 15e is provided at the extending edge of the support plate portion 16c.The strip 16 is installed at the opposite parts of each first longitudinal frame 14, 15 in the following manner, that is, the extended edge of the engaging foot 16d is engaged with the strip hooks 14d, 15d of the first longitudinal frames 14, 15, and the engaging portion 16g of the supporting plate portion 16c is engaged with the sealing mounting portions 14e, 15e of the first longitudinal frames 14, 15, and then the fixing screw 16h is screwed to the extended edge of the fixing foot 16e through the outer base wall portion 14a and the inner base wall portion 15a.

[0066] In the frame 10B below where the strip 16 is installed, after the lower edge of the panel P1 is assembled between the lower inner panel clamping wall 13c and the lower outer panel clamping wall 13d of the first lower frame 13, the pressure edge 12g is installed on the strips 16, 16 of the first cross bar 12 and the first vertical frames 14, 15, respectively, thereby forming the first fixed window M12. The portions of the first cross bar 12, the first lower frame 13, and the first vertical frames 14, 15 that abut against the surface of the panel P1 are respectively provided with sealing members S2. In the first fixed window M12, when viewed from the indoor side, the edge of the strip 16 and the pressure edge 12g that support the panel P1 located on the inner peripheral side will not exceed the inner frame inner main visual wall 15c of the first inner vertical frame 15 or the outer frame inner main visual wall 14c of the first outer vertical frame 14 and be exposed to the inner peripheral side, which is advantageous in terms of appearance quality.

[0067] In addition, as described above, the gap d1 to be ensured between the window sash 20 and the first inner longitudinal frame 15 in the upper frame 10A and the gap L1 to be ensured between the strip base plate portion 16a and the first inner longitudinal frame 15 in the lower frame 10B are substantially the same. Therefore, the gap d1 to be ensured between the first inner longitudinal frame 15 and the longitudinal side frame 23 of the window sash 20 in the upper frame 10A and the gap L1 to be ensured between the first inner longitudinal frame 15 and the strip base plate portion 16a of the strip 16 in the lower frame 10B extend on the same straight line across the first crosspiece 12. That is, although different window types are arranged side by side in the upper frame 10A and the lower frame 10B, the left and right first longitudinal frames 14 and 15 extend on the same straight line respectively, and the longitudinal frame 23 and the pressure edge 25 of the edge of the supporting panel P1 and the pressure edge 12g of the strip 16 have the same appearance size and extend on the same straight line. Furthermore, the gap d1 between the first inner longitudinal frame 15 and the longitudinal frame 23 and the gap L1 between the first inner longitudinal frame 15 and the strip 16 have the same appearance size and extend on the same straight line, which is advantageous in terms of the appearance quality when observed from the outdoor side.

[0068] The second longitudinal window W2

[0069] The second upper frame 41 has an upper base wall portion 41a, an upper inner main viewing wall portion 41b, and an upper inner panel clamping wall portion 41c, and is configured to have a dimension along the depth direction that is substantially the same as that of the first upper frame 11. The upper base wall portion 41a extends substantially horizontally along the depth direction. An upper groove forming wall portion 41d is provided at the edge portion located outside the room in the upper surface of the upper base wall portion 41a. The upper groove forming wall portion 41d extends upward from the upper base wall portion 41a along the main viewing surface direction, then extends outside the room along the depth direction, and then extends upward along the main viewing surface direction, thereby forming a gap groove portion 41e that opens to the outside of the room above the upper base wall portion 41a. On the depth surface below the upper base wall portion 41a, a press edge 12g is installed on the part outside the room. The edge clamp 12g is the same as the edge clamp provided on the first upper frame 11, and has a mounting portion 12h and a panel clamp portion 12i, and the panel clamp portion 12i extends downward from the depth surface of the inner peripheral side of the upper base wall portion 41a in the direction of the main viewing surface. The upper inner main viewing wall portion 41b extends upward and downward in the direction of the main viewing surface from the edge of the upper base wall portion 41a located on the indoor side. The upper inner panel clamping wall portion 41c extends downward in the direction of the main viewing surface from a portion of the depth surface below the upper base wall portion 41a that is slightly closer to the outdoor side than the center. Between the extended edge of the upper inner panel clamping wall portion 41c and the lower edge of the upper inner main viewing wall portion 41b, an upper hollow portion 41g is formed by the upper depth wall portion 41f. The protruding dimension of the upper inner panel clamping wall portion 41c from the upper base wall portion 41a is substantially the same as that of the panel clamping portion 12i of the edge clamp 12g. Although not explicitly shown in the figure, the second upper frame 41 is constructed so that when the upper inner main viewing wall portions 11e and 41b are aligned with each other relative to the first upper frame 11, the upper base wall portion 41a is located at approximately the same height as the upper frame 21 of the first longitudinal window W1, and the portion of the upper groove wall portion 41d extending along the main viewing surface direction is located at approximately the same height as the upper panel cover wall portion 11b of the first upper frame 11.

[0070] The second crosspiece 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 hollow in a special shape. That is, the middle base 42a extends in a plane with the part facing the room, the upper part and the lower part respectively, and the central part of the part facing the outdoor protrudes to the outdoor in a hat-shaped manner, and has recessed parts 42d and 42e at the upper corner edge and the lower corner edge on the outdoor side respectively. The middle upper panel clamping wall 42b extends from the upper part of the part protruding to the outdoor side of the middle base 42a to the outdoor side roughly horizontally along the depth direction, and then extends upward along the main viewing surface direction. The size of the middle upper panel clamping wall 42b along the main viewing surface direction is roughly the same as the size of the main viewing surface facing the outdoor of the lower frame 22 of the window sash 20 of the first longitudinal window W1. The upper edge of the middle upper panel clamping wall 42b is located at a position roughly the same as the upper surface of the middle base 42a. The lower portion of the middle panel cover wall 42c protrudes from the middle base 42a toward the outside of the room and extends approximately horizontally toward the outside in the depth direction. A dimension d3 approximately the same as the following gap d2 is ensured between the middle panel cover wall 12b of the first cross bar 12 constituting the upper frame 10A in the first longitudinal window W1 and the outer peripheral depth surface of the portion of the lower frame 22 of the window sash 20 located outside the room. A press edge 12g is installed on the outdoor side portion of the depth surface below the middle panel cover wall 42c. The press edge 12g is the same as the press edge provided on the second upper frame 41, and has a mounting portion 12h and a panel clamping portion 12i, and the panel clamping portion 12i extends downward from the inner peripheral depth surface of the middle panel cover wall 42c toward the main viewing surface.

[0071] The second lower frame 43 has a lower base wall 13 a , a lower inner main viewing wall 13 b , a lower inner panel clamping wall 13 c , and a lower outer panel clamping wall 13 d , and has the same cross-sectional shape as the first lower frame 13 .

[0072] The second vertical frames 44, 44 are symmetrical in shape and are configured to have approximately the same size along the length direction as the first vertical frames 14, 15. In the illustrated example, the second vertical frames 44, 44 are configured to have a vertical base wall portion 44a, a vertical inner main viewing wall portion 44b, and a vertical inner panel clamping plate portion 44c. The vertical base wall portion 44a, the vertical inner main viewing wall portion 44b, and the vertical inner panel clamping plate portion 44c correspond to the upper base wall portion 41a, the upper inner main viewing 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 depth direction. On the depth surface of the inner peripheral side of the vertical base wall portion 44a, a press edge 12g is installed on the outdoor side portion. The edge clamp 12g is the same as the edge clamp provided on the second upper frame 41, and has a mounting portion 12h and a panel clamping portion 12i, and the panel clamping portion 12i extends from the depth surface of the inner peripheral side of the longitudinal base wall portion 44a to the inner peripheral side along the main viewing surface direction. The longitudinal inner main viewing wall portion 44b extends from the edge of the longitudinal base wall portion 44a located on the indoor side to the inner peripheral side along the main viewing surface direction. As can be seen from the figure, the longitudinal inner main viewing wall portion 44b of this embodiment is configured to have a plate thickness greater than the longitudinal base wall portion 44a (almost 3 times in the example shown in the figure). A longitudinal locking protrusion 44d is provided on the indoor side of the extended edge of the longitudinal inner main viewing wall portion 44b. The longitudinal locking protrusion 44d is paired with the inner locking protrusion 15f of the first inner longitudinal frame 15, and has a locking recess 44e and an introduction inclined surface 44f on the inner peripheral side, protruding to the indoor side. The longitudinal inner panel clamping plate portion 44c extends from the portion of the inner peripheral side of the longitudinal base wall portion 44a corresponding to the lower inner panel clamping wall portion 13c toward the inner peripheral side along the main viewing surface direction. Between the extended edge of the longitudinal inner panel clamping plate portion 44c and the inner peripheral edge of the longitudinal inner main viewing wall portion 44b, a longitudinal hollow portion 44h is formed by the longitudinal depth wall portion 44g. The protruding dimension of the longitudinal inner panel clamping plate portion 44c from the longitudinal base wall portion 44a is substantially the same as that of the panel clamping portion 12i of the pressure edge 12g.

[0073] In addition, in the second vertical frames 44, 44, a vertical engaging piece 44i and a vertical superimposing piece 44j are provided on the depth surface of the outer peripheral side of the vertical base wall portion 44a. The vertical engaging piece 44i extends from the portion of the vertical base wall portion 44a that is closer to the indoor side than the edge portion located on the outdoor side to the outer peripheral side and then bends, and extends to the outdoor side in the depth direction, and a gap is formed between the vertical base wall portion 44a and the vertical base wall portion 44a, in which the inner engaging piece 15i of the first inner vertical frame 15 can be engaged. The vertical superimposing piece 44j protrudes from the edge portion located on the indoor side of the vertical base wall portion 44a to the outer peripheral side in the main viewing surface direction, and is provided in such a manner that when the vertical engaging piece 44i is engaged with the inner engaging piece 15i, the vertical superimposing piece 44j can be superimposed on the inner superimposing piece 15j of the first inner vertical frame 15 from the indoor side. The plate thickness of the longitudinal superimposed sheet 44j is substantially the same as that of the longitudinal inner main viewing wall portion 44b, and is set in the following manner: when the longitudinal superimposed sheet 44j is superimposed on the inner superimposed sheet 15j from the indoor side, the main viewing surface of the longitudinal inner main viewing wall portion 44b facing the indoor side and the main viewing surface of the inner frame inner main viewing wall portion 15c facing the indoor side are located on the same plane along the main viewing surface direction. In addition, at this time, the edge of the longitudinal base wall portion 44a located on the outdoor side and the edge of the inner base wall portion 15a located on the outdoor side are located on the same plane along the main viewing surface direction. The protruding dimension of the longitudinal superimposed sheet 44j from the longitudinal base wall portion 44a is substantially equal to the protruding dimension of the inner superimposed sheet 15j from the inner base wall portion 15a. A fitting protrusion (fitting portion) 44k is provided at the extended edge of the longitudinal superimposed sheet 44j at the portion located on the outdoor side. The engaging protrusion 44k is used to engage with the engaging groove portion 15k of the inner overlapping piece 15j, and when engaged with the engaging groove portion 15k, it is in the following state: the extended end surface (specified surface) 44m of the longitudinal overlapping piece 44j abuts against the depth surface of the outer peripheral side of the inner base wall portion 15a, and the surface of the longitudinal overlapping piece 44j facing the outside of the room abuts against the surface of the inner overlapping piece 15j facing the inside of the room.

[0074] In the second longitudinal connecting window W2 having the second upper frame 41, the second cross bar 42, the second lower frame 43, and the second vertical frames 44, 44 configured in the above manner, the upper frame 10C is formed by the second upper frame 41, the second cross bar 42, and the second vertical frames 44, 44, and the lower frame 10D is formed by the second cross bar 42, the second lower frame 43, and the second vertical frames 44, 44. The second upper fixed window M21 and the second lower fixed window M22 are formed by arranging panels P2, P3 having the same outer dimensions in each frame 10C, 10D. That is, in the upper frame 10C, after the lower edge of the panel P2 is assembled between the recessed portion 42d provided at the upper corner edge of the second cross bar 42 and the middle upper panel clamping wall portion 42b, the pressing edge 12g is installed on each of the second upper frame 41 and the second vertical frames 44, 44, thereby forming the second upper fixed window M21. The second upper frame 41, the second crosspiece 42, and the second longitudinal frames 44, 44 are provided with sealing members S2 in the portions that abut against the surface of the panel P2. Similarly, in the lower frame 10D, after the lower edge of the panel P3 is assembled between the lower inner panel clamping wall 13c and the lower outer panel clamping wall 13d of the second lower frame 43, the pressing edge 12g is installed on each of the second crosspiece 42 and the second longitudinal frames 44, 44, thereby forming the second lower fixed window M22. The second crosspiece 42, the second lower frame 43, and the second longitudinal frames 44, 44 are provided with sealing members S2 in the portions that abut against the surface of the panel P2. The second crosspiece 42 is provided at a position in which the upper surface of the middle lower panel cover wall 42c is consistent with the upper surface of the middle panel cover wall 12b in the first crosspiece 12.

[0075] Door and window structure

[0076] In order to connect the first longitudinal connecting window W1 and the second longitudinal connecting window W2 to each other, firstly, the inner engaging piece 15i provided on the first inner longitudinal frame 15 is engaged with the longitudinal engaging piece 44i provided on the second longitudinal frame 44, and Figure 8As shown, the longitudinal superimposed piece 44j provided on the second longitudinal frame 44 is overlapped with the inner superimposed piece 15j provided on the first inner longitudinal frame 15 from the indoor side, and the engaging protrusion 44k is engaged with the engaging groove 15k. In the state where the engaging protrusion 44k is engaged with the engaging groove 15k, the extended end surface 44m of the longitudinal superimposed piece 44j is maintained in a state of abutting against the depth surface of the outer peripheral side of the inner base wall 15a. That is, on the outdoor side, the engagement of the inner engaging piece 15i with the longitudinal engaging piece 44i restricts the first inner longitudinal frame 15 and the second longitudinal frame 44 from moving in directions away from each other, and on the indoor side, the engagement of the engaging protrusion 44k with the engaging groove 15k restricts the first inner longitudinal frame 15 and the second longitudinal frame 44 from moving in directions away from each other. In addition, the extended edge of the inner engaging piece 15i abuts against the longitudinal base wall 44a, and the extended end surface 44m of the longitudinal overlapping piece 44j abuts against the inner base wall 15a, thereby accurately defining the interval between the first inner longitudinal frame 15 and the second longitudinal frame 44. Figure 6 and Figure 7 As shown, by screwing the screw member B1 to the inner overlapping piece 15j via the longitudinal overlapping piece 44j, the first longitudinal connecting window W1 and the second longitudinal connecting window W2 can be connected to each other in a state where the dimension along the main viewing surface direction is accurately defined. Moreover, in this door and window, the first longitudinal connecting window W1 and the second longitudinal connecting window W2 are connected without the need for a longitudinal stile member or a middle stile member, so that the increase in manufacturing cost and external dimensions can be suppressed. Furthermore, by installing the cover member C1 along the length direction on the first inner longitudinal frame 15 and the second longitudinal frame 44 exposed to the inner side of the room via the inner locking protrusion 15f and the longitudinal locking protrusion 44d respectively provided, it is possible to prevent the connecting portion or the screw member B1 from being exposed, which is also preferred in terms of design.

[0077] Between the first longitudinal connecting window W1 and the second longitudinal connecting window W2 connected to each other, a groove-shaped recessed portion 2 opened to the outside is formed in the portion surrounded by the inner base wall portion 15a, the inner engaging piece 15i, and the longitudinal base wall portion 44a. Therefore, by filling the recessed portion 2 with the sealing material S4, water or air can be prevented from flowing between the first longitudinal connecting window W1 and the second longitudinal connecting window W2 between the indoor and outdoor, which is advantageous in terms of water tightness and air tightness.

[0078] Moreover, the gap d4 to be ensured between the first upper frame 11 and the upper frame 21 of the window sash 20 in the first longitudinal connecting 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 longitudinal connecting window W2 have the same appearance size and extend in the left-right direction at the same height position. Similarly, the gap d2 to be ensured between the middle panel cover wall portion 12b of the first cross bar 12 and the lower frame 22 of the window sash 20 in the first longitudinal connecting window W1 and the gap d3 between the middle lower panel cover wall portion 42c of the second cross bar 42 and the middle upper panel clamping wall portion 42b in the second longitudinal connecting window W2 have the same appearance size and extend in the left-right direction at the same height position. Therefore, in the two adjacent longitudinal connecting windows W1 and W2, the gap extending in the left-right direction is also continuous, which is advantageous in terms of appearance quality when observed from the outdoor side.

[0079] Furthermore, the size of the gaps to be ensured on both sides of the first longitudinal connecting window W1 and the second longitudinal connecting window W2 are different through the first inner longitudinal frame 15. However, by connecting the first longitudinal connecting window W1 to both sides of the second longitudinal connecting window W2 in a mutually symmetrical manner, a shape that is bilaterally symmetrical with the second longitudinal connecting window W2 as the center is formed. Therefore, the appearance quality of the door and window when viewed from the outdoor side is preferred.

[0080] In addition, in the above-mentioned embodiment, the protruding dimension of the inner snap-fitting piece 15i from the first inner longitudinal frame 15 is larger than the protruding dimension of the longitudinal snap-fitting piece 44i from the second longitudinal frame 44, but it can also be configured that the protruding dimension of the longitudinal snap-fitting piece 44i from the second longitudinal frame 44 is larger than the protruding dimension of the inner snap-fitting piece 15i from the first inner longitudinal frame 15.

[0081] In addition, in the above-mentioned embodiment, although the example of connecting a plurality of vertically connected windows W1 and W2 to the left and right is shown, the connected frames do not need to be vertically connected windows.

[0082] Modification 1

[0083] In the above embodiment, examples are given of a horizontally connected window of a vertically sliding window M11 and a fixed window, and a horizontally connected window of a fixed window and a fixed window, but the window types of the frame connected left and right are not limited to these. Fig. 9 In the variation example 1 shown, a longitudinal slide-out window M11 and a transverse connecting window of the longitudinal slide-out window M11 are shown. The frame of the longitudinal slide-out window M11 shown on the left side of the figure (hereinafter referred to as the first frame 10E when it is necessary to distinguish) has the same structure as the frame 10A above the first longitudinal connecting window W1 shown in the embodiment. Therefore, for the first frame 10E, the same symbols as in the embodiment are marked, and detailed descriptions are omitted. In contrast, the frame of the longitudinal slide-out window M11 shown on the right side of the figure (hereinafter referred to as the second frame 10F when it is necessary to distinguish) is only a structure of a longitudinal frame adjacent to the first frame 10E, which is different from the first frame 10E.

[0084] That is, the longitudinal frame (frame material) 50 of the second frame body 10F has a longitudinal base wall portion 50a, a longitudinal door stop wall portion 50b, and a longitudinal inner main viewing wall portion 50c. The longitudinal base wall portion 50a extends approximately vertically along the depth direction. The longitudinal door stop wall portion 50b extends from the depth surface of the inner peripheral side of the longitudinal base wall portion 50a to the inner peripheral side. In the extended edge portion of the longitudinal door stop wall portion 50b, the main viewing surface facing the outside is installed with a sealing component S1 via a sealing mounting portion 50d. The longitudinal inner main viewing wall portion 50c extends from the edge portion of the longitudinal base wall portion 50a located on the indoor side to the inner peripheral side along the main viewing surface direction. The protruding dimension of the longitudinal inner main viewing wall portion 50c to the inner peripheral side is approximately equal to the protruding dimension of the longitudinal door stop wall portion 50b. The plate thickness dimension of the longitudinal inner main viewing wall portion 50c is configured to be larger than the longitudinal base wall portion 50a. A vertical locking projection 50e is provided on the indoor inner portion of the extended edge of the vertical inner main wall portion 50c. The vertical locking projection 50e has an engagement recess 50f and an introduction inclined surface 50g on the inner peripheral portion and protrudes toward the indoor inner side.

[0085] In addition, in the longitudinal frame 50, a longitudinal engaging piece 50h and a longitudinal superimposing piece 50i are provided on the depth surface of the outer peripheral side of the longitudinal base wall portion 50a. The longitudinal engaging piece 50h extends from a portion of the longitudinal base wall portion 50a that is closer to the indoor side than the edge portion located on the outdoor side to the outer peripheral side and then bends, and extends to the outdoor side in the depth direction, and a gap is formed between the longitudinal base wall portion 50a and the longitudinal base wall portion 50a, in which the inner engaging piece 15i of the first inner longitudinal frame 15 can be engaged. The longitudinal superimposing piece 50i protrudes from the edge portion located on the indoor side of the longitudinal base wall portion 50a to the outer peripheral side in the main viewing surface direction, and is provided in such a manner that when the longitudinal engaging piece 50h is engaged with the inner engaging piece 15i, the longitudinal superimposing piece 50i can be superimposed with the inner superimposing piece 15j of the first inner longitudinal frame 15 from the indoor side. The plate thickness of the longitudinal superimposed sheet 50i is substantially the same as that of the longitudinal inner main visual wall portion 50c, and is set in the following manner: when the longitudinal superimposed sheet 50i is superimposed on the inner superimposed sheet 15j from the indoor side, the main visual surface of the longitudinal inner main visual wall portion 50c facing the indoor side and the main visual surface of the inner frame inner main visual wall portion 15c facing the indoor side are located on the same plane along the main visual surface direction. In addition, at this time, the edge of the longitudinal base wall portion 50a located on the outdoor side and the edge of the inner base wall portion 15a of the first inner longitudinal frame 15 located on the outdoor side are located on the same plane along the main visual surface direction. The protruding dimension of the longitudinal superimposed sheet 50i from the longitudinal base wall portion 50a is substantially equal to the protruding dimension of the inner superimposed sheet 15j from the inner base wall portion 15a. A fitting protrusion 50j is provided at the extended edge of the longitudinal superimposed sheet 50i at the portion located on the outdoor side. The mating protrusion 50j is used to be mated with the mating groove portion 15k of the inner overlapping piece 15j, and when mated with the mating groove portion 15k, the following state is achieved: the extended end surface (specified surface) of the longitudinal overlapping piece 50i abuts against the depth surface of the outer peripheral side of the inner base wall portion 15a, and the surface of the longitudinal overlapping piece 50i facing the outside of the room abuts against the surface of the inner overlapping piece 15j facing the inside of the room.

[0086] As can be seen from the figure, in the longitudinal frame 50, the inner peripheral edge (first inner peripheral edge) 25a of the edge portion of the pressure edge 25 of the surface facing the outside of the supporting panel 24, and the inner peripheral edge (second inner peripheral edge) 23b of the longitudinal frame 23 of the surface facing the indoor of the supporting panel 24 are located on the same vertical plane along the depth direction relative to the innermost edge (frame material edge) 50k of the longitudinal inner main visual wall 50c. Therefore, when observed from the indoor side, the longitudinal frame 23 and the pressure edge 25 of the window sash 20 will not exceed the longitudinal frame 50 and be exposed to the inner peripheral side, which is advantageous in terms of appearance quality.

[0087] In this modification 1, in order to connect the left and right frames 10E and 10F, first, the inner engaging piece 15i provided on the first inner longitudinal frame 15 is engaged with the longitudinal engaging piece 50h provided on the longitudinal frame 50, and the longitudinal superposition piece 50i provided on the longitudinal frame 50 is superposed on the inner superposition piece 15j provided on the first inner longitudinal frame 15 from the indoor side, and the engaging protrusion 50j is engaged with the engaging groove 15k. In the state where the engaging protrusion 50j is engaged with the engaging groove 15k, the extended end surface of the longitudinal superposition piece 50i is maintained in contact with the deep surface of the outer peripheral side of the inner base wall 15a, and the movement in the direction away from each other is restricted, and the interval between the first inner longitudinal frame 15 and the longitudinal frame 50 is accurately determined. Therefore, if the screw member B1 is screwed to the inner superimposed piece 15j via the longitudinal superimposed piece 50i from this state, the two frames 10E and 10F can be connected to each other in a state where the dimensions along the main viewing surface direction are accurately defined. In the door and window of this modified example, the left and right frames 10E and 10F are connected without the need for longitudinal stile members or middle stile members, so the increase in manufacturing cost and external dimensions can be suppressed. Furthermore, on the first inner longitudinal frame 15 and the longitudinal frame 50 exposed to the indoor side, by installing the cover member C1 along the length direction via the inner stop protrusion 15f and the longitudinal stop protrusion 50e respectively provided, it is possible to prevent the connection part or the screw member B1 from being exposed, which is also preferred in terms of design.

[0088] Between the mutually connected frames 10E and 10F, a groove-shaped recess 2 opening to the outside is formed in the portion surrounded by the inner base wall 15a, the inner engaging piece 15i, and the longitudinal base wall 50a. Therefore, by filling the recess 2 with a sealing material S4, water or air can be prevented from flowing between the frames 10E and 10F between the indoor and outdoor, which is advantageous in terms of water tightness and air tightness. In addition, the shape becomes bilaterally symmetrical when viewed from the outdoor side, so it is advantageous in terms of appearance quality.

[0089] In this modification example 1, it is sufficient to appropriately adjust the protruding dimensions of the inner snap-fitting piece 15i, the protruding dimensions of the inner overlapping piece 15j, the protruding dimensions of the longitudinal overlapping piece 50i, and the dimensions of the gaps to be ensured between each frame 10E, 10F and each window sash 20. For example, the cover part C1 shown in the embodiment can be directly applied by setting the following dimension d5 to be equal to the following dimension d6, that is, the dimension d5 is the dimension from the innermost edge of the longitudinal frame 23 and the pressure edge 25 in the first frame 10E to the innermost edge of the longitudinal frame 23 and the pressure edge 25 in the second frame 10F, and the dimension d6 is the dimension from Fig. 9In the embodiment shown in (b), the dimension from the innermost edge of the longitudinal frame 23 and the pressing edge 25 in the first longitudinal connecting window W1 to the innermost edge of the second longitudinal frame 44 and the pressing edge 12g in the second longitudinal connecting window W2 is shown. Furthermore, the connecting parts of the longitudinal frames 50 exposed when viewed from the outside can be arranged on the same straight line with the same appearance dimensions, without worrying about the loss of appearance quality.

[0090] Modification 2

[0091] In the above embodiment, as an example of the first inner vertical frame 15, the inner base wall portion 15a is shown to be flat, and as an example of the second vertical frame 44, the inner base wall portion 15a is shown to have a vertical hollow portion 44h, but the present invention is not limited to these. Fig.10 In the variation example 2 shown, the first inner longitudinal frame (frame material) 60 used is hollow, and the second longitudinal frame (frame material) 61 used is flat. That is, in the first inner longitudinal frame 60 of variation example 2, compared with the embodiment, the inner snap-fitting piece 60i and the inner overlapping piece 60j are respectively extended, and an inner depth wall portion 60m along the depth direction is provided between the extended inner snap-fitting 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 snap-fitting piece 60i and the inner overlapping piece 60j from the inner depth wall portion 60m are respectively the same as the protruding dimensions from the inner base wall portion 15a in the embodiment. On the other hand, in the second longitudinal frame 61 of variation example 2, the longitudinal depth wall portion 44g is omitted, thereby opening the space between the longitudinal inner panel clamping plate portion 44c and the longitudinal inner main visual wall portion 44b. For Fig.10 In the second variation shown, the same structures as those in the embodiment are denoted by the same reference numerals as those in the embodiment.

[0092] In this modification example 2, similarly to the embodiment, the inner engaging piece 60i provided on the first inner longitudinal frame 60 is engaged with the longitudinal engaging piece 44i provided on the second longitudinal frame 61, and the longitudinal overlapping piece 44j provided on the second longitudinal frame 61 is overlapped with the inner overlapping piece 60j provided on the first inner longitudinal frame 60 from the indoor side. If a screw member (not shown) is screwed to the inner overlapping piece 60j via the longitudinal overlapping piece 44j from this state, the two can be connected in a state in which the dimension along the main viewing surface direction is accurately defined. Of course, in modification example 2, although the screw member and the cover member are omitted, they are provided similarly to the embodiment.

[0093] A groove-shaped recessed portion 3 opening to the outside is formed between the first inner longitudinal frame 60 and the second longitudinal frame 61 connected to each other in a portion surrounded by the inner base wall portion 15a, the inner engaging piece 60i, and the longitudinal base wall portion 44a. Therefore, by filling the recessed portion 3 with the sealing material S4, water or air can be prevented from flowing between the first inner longitudinal frame 60 and the second longitudinal frame 61 between the indoor and outdoor, which is advantageous in terms of water tightness and air tightness.

[0094] Modification 3

[0095] In the above embodiment, as an example of the first inner vertical frame 15, the inner base wall portion 15a is shown to be flat, and as an example of the second vertical frame 44, the vertical base wall portion 44a is shown to be flat, but the present invention is not limited to these. Fig.11 In the variation example 3 shown, a bridge member 63 made of a resin material is sandwiched between the inner base wall portion 15a and the inner depth wall portion 60m in the first inner longitudinal frame 60 shown in the variation example 2. Similarly, in the second longitudinal frame (frame material) 64, the portion of the longitudinal base wall portion 44a that is closer to the outside of the room than the longitudinal inner panel clamping plate portion 44c is formed into a hollow shape, and a bridge member 65 made of a resin material is sandwiched in the middle thereof. According to this variation example 3, the same effects as those of the embodiment can be achieved, and the heat transfer between the indoor and outdoor through the first inner longitudinal frame 60 and the second longitudinal frame 64 can be blocked by the bridge members 63 and 65, so it is advantageous in terms of thermal insulation. For Fig.11 In the modification example 3 shown, the same structures as those in the embodiment are marked with the same reference numerals as those in the embodiment. Fig.11 Reference numeral 66 in the figure denotes a bridge member which is interposed between the indoor side portion and the outdoor side portion of the vertical frame 23 of the window sash 20 and is made of a resin material.

[0096] Modification 4

[0097] In the above embodiment, a screen window 30 is provided on the indoor side of the longitudinally sliding window M11, but it may also be provided as Fig.12 As shown in the modification 4, the screen 30 is omitted and the left and right vertical frames are connected. The same symbols are marked for the same structures in the modification 4 as those in the embodiment. In addition, in the modification 4, the inner main viewing wall portion 15c of the inner frame is omitted, and the inner locking protrusion 15f is provided on the inner door stop wall portion 15b, but the inner door stop wall portion 15b can also be omitted, and the sealing installation portion 15e is provided on the inner peripheral side edge to install the inner sealing component S1, so as to give the inner main viewing wall portion 15c of the inner frame a door stop function.

[0098] Modification 5

[0099] In the above-mentioned embodiment, a horizontally connected window formed by connecting the frames arranged side by side on the left and right is exemplified, but the present invention is not limited thereto. Fig.13 The variant example 5 shown can also be applied similarly to the frames arranged side by side in the upper and lower parts. That is, the door and window shown in the variant example 5 is the same as the first longitudinal window W1 of the embodiment, and has an upper longitudinal sliding window M11 and a lower fixed window, and the lower frame (frame material) 71 of the upper frame (hereinafter, referred to as the upper frame 10A when it is necessary to distinguish) and the upper frame (frame material) 72 of the lower frame (hereinafter, referred to as the lower frame 10B when it is necessary to distinguish) are connected to each other. In addition, in the door and window of the variant example 5, except for the lower frame 71 of the upper frame 10A and the upper frame 72 of the lower frame 10B, the other structures are the same as the first longitudinal window W1 of the embodiment. Therefore, the following mainly describes the lower frame 71 of the upper frame 10A and the upper frame 72 of the lower frame 10B, and the same symbols are marked for the same structures as the embodiment, and the description is omitted.

[0100] The lower frame 71 of the upper frame 10A has a lower base wall 71a, a lower window sash cover wall 71b, a lower door stop wall 71c, a lower screen cover wall 71d, and a lower inner main viewing wall 71e. The lower base wall 71a extends roughly horizontally along the depth direction. The lower window sash cover wall 71b protrudes downward from the edge of the lower base wall 71a on the outdoor side, and then extends to the outdoor along the depth direction. The lower door stop wall 71c extends upward along the main viewing surface direction from the edge of the lower base wall 71a located on the indoor side. The inner side sealing component S1 is installed in the portion facing the outdoor in the extended edge of the lower door stop wall 71c via the sealing mounting portion 71f. The lower screen cover wall 71d protrudes downward from the edge of the lower base wall 71a located on the indoor side, and then extends to the indoor along the depth direction. The lower inner main viewing wall portion 71e extends upward along the main viewing surface direction from the edge of the lower screen cover wall portion 71d located on the indoor side. As can be seen from the figure, the lower inner main viewing wall portion 71e of Modification 5 is configured to have a plate thickness greater than the lower base wall portion 71a. A lower locking protrusion 71g is provided on the indoor side of the extended edge of the lower inner main viewing wall portion 71e. The lower locking protrusion 71g has a locking recess 71h and an introduction inclined surface 71i at the upper part, and protrudes toward the indoor side.

[0101] In addition, in the lower frame 71, a lower engaging piece 71j is provided on the depth surface below the lower window sash cover wall portion 71b, and a lower superimposing piece 71k is provided on the depth surface below the lower screen cover wall portion 71d. The lower engaging piece 71j extends downward from a portion of the lower window sash cover wall portion 71b that is closer to the indoor side than the edge portion located on the outdoor side, then bends, and extends toward the indoor side along the depth direction. The lower superimposing piece 71k extends downward from a portion of the lower screen cover wall portion 71d that is closer to the outdoor side than the edge portion located on the indoor side. An engaging groove portion (engaging portion) 71m is provided on the portion of the lower superimposing piece 71k that is located at the connection portion with the lower screen cover wall portion 71d in the main viewing surface facing the indoor side.

[0102] 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 side depth wall portion 72c, an upper inner side panel clamping wall portion 72d, and an upper inner side main viewing wall portion 72e. The upper base wall portion 72a extends approximately horizontally along the depth direction. The upper panel cover wall portion 72b protrudes upward from the edge of the upper base wall portion 72a located on the outdoor side, and then extends to the outdoor side along the depth direction. On the depth surface below the upper panel cover wall portion 72b, a press edge 12g is installed on the outdoor side. The press edge 12g is the same as the press edge used in the embodiment, and has a mounting portion 12h and a panel clamping portion 12i. The upper inner side depth wall portion 72c protrudes upward from the edge of the upper base wall portion 72a located on the indoor side, and then extends to the indoor side along the depth direction. The upper inner panel clamping wall portion 72d extends downwardly in the main viewing direction from the depth surface below the upper base wall portion 72a. The protruding dimension of the upper inner panel clamping wall portion 72d from the upper base wall portion 72a is substantially the same as that of the panel clamping portion 12i of the edge 12g. The upper inner main viewing wall portion 72e extends downwardly in the main viewing direction from the edge portion of the upper inner depth wall portion 72c located on the indoor side. The plate thickness of the upper inner main viewing wall portion 72e is substantially the same as that of the lower inner main viewing wall portion 71e. An upper locking protrusion 72f is provided in the portion on the indoor side of the extended edge portion of the upper inner main viewing wall portion 72e. The upper locking protrusion 72f is paired with the lower locking protrusion 71g of the lower frame 71, and has a locking recess 72g and an introduction inclined surface 72h in the lower portion, protruding toward the indoor side. An upper hollow portion 72j is formed by the upper deep wall portion 72i between the extending edge of the upper inner main wall portion 72e and the lower edge of the upper inner panel clamping wall portion 72d.

[0103] In addition, in the upper frame 72, an upper engaging piece 72k is provided on the depth surface above the upper panel cover wall portion 72b, and an upper superimposing piece 72m is provided on the edge of the upper inner side depth wall portion 72c on the indoor side. The upper engaging piece 72k extends upward from a portion of the upper panel cover wall portion 72b that is closer to the indoor side than the edge located on the outdoor side, and then bends, and extends toward the outdoor side in the depth direction, and a gap is formed between the upper panel cover wall portion 72b and the upper panel cover wall portion 72b so that the lower engaging piece 71j of the lower frame 71 can be engaged. The upper superimposing piece 72m protrudes upward from the edge located on the indoor side of the upper inner side depth wall portion 72c in the main viewing direction, and is provided in such a manner that when the upper engaging piece 72k is engaged with the lower engaging piece 71j, the upper superimposing piece 72m is superimposed on the lower superimposing piece 71k of the lower frame 71 from the indoor side. The thickness of the upper overlapping piece 72m is substantially the same as that of the upper inner main visual wall portion 72e, and is set in the following manner: when the upper overlapping piece 72m overlaps with the lower overlapping piece 71k from the indoor side, the main visual surface of the upper inner main visual wall portion 72e facing the indoor side and the main visual surface of the lower inner main visual wall portion 71e facing the indoor side are located on the same plane along the direction of the main visual surface. In addition, at this time, the edge of the lower sash cover wall portion 71b located on the outdoor side and the edge of the upper panel cover wall portion 72b located on the outdoor side are located on the same plane along the direction of the main visual surface. A fitting protrusion (fitting portion) 72n is provided at the extended edge of the upper overlapping piece 72m at the portion located on the outdoor side. The engaging protrusion 72n is used to engage with the engaging groove portion 71m of the lower overlapping piece 71k, and when engaged with the engaging groove portion 71m, the following state is achieved: the extended end surface (specified surface) 72p of the upper overlapping piece 72m abuts against the lower depth surface of the lower screen cover wall portion 71d, and the surface of the upper overlapping piece 72m facing the outside and the surface of the lower overlapping piece 71k facing the inside abut against each other.

[0104] In this modification 5, in order to assemble the upper and lower frames 10A and 10B, first, the lower engaging piece 71j provided on the lower frame 71 is engaged with the upper engaging piece 72k provided on the upper frame 72, and the upper superimposing piece 72m provided on the upper frame 72 is superimposed on the lower superimposing piece 71k provided on the lower frame 71 from the indoor side, and the engaging protrusion 72n is engaged with the engaging groove 71m. In the state where the engaging protrusion 72n is engaged with the engaging groove 71m, the extended end surface 72p of the upper superimposing piece 72m maintains a state of contacting the lower depth surface of the lower screen cover wall 71d, restricting the movement in the direction of departure from each other, and accurately defining the interval between the lower frame 71 and the upper frame 72. Therefore, if the screw member B1 is screwed to the lower overlapping piece 71k via the upper overlapping piece 72m from this state, the two frames 10A and 10B can be connected to each other in a state where the dimensions along the main viewing surface direction are accurately defined. By installing the cover member C2 along the length direction via the lower locking protrusion 71g and the upper locking protrusion 72f respectively provided on the lower frame 71 and the upper frame 72 exposed to the indoor side, it is possible to prevent the connection part or the screw member B1 from being exposed, which is also preferred in terms of design.

[0105] Between the mutually connected frames 10A and 10B, a groove-shaped recessed portion 4 opening to the outside is formed in the portion surrounded by the lower sash cover wall portion 71b, the lower engaging piece 71j, and the upper panel cover wall portion 72b. Therefore, by filling the recessed portion 4 with a sealing material S4, water or air can be prevented from circulating between the upper frame 10A and the lower frame 10B between the indoor and outdoor, which is advantageous in terms of water tightness and air tightness.

[0106] In addition, in the above-mentioned embodiment, as the so-called hidden frame, the first inner peripheral side edge portion located on the inner peripheral side of the edge portion of the edge portion of the surface facing the outside of the supporting panel or the longitudinal frame, and the second inner peripheral side edge portion located on the inner peripheral side of the edge portion of the edge portion of the surface facing the room of the supporting panel or the longitudinal frame are respectively arranged in the following positions in the depth direction, that is, the position is the same as the frame material edge portion located on the inner peripheral side of the main viewing surface of the longitudinal frame facing the room or is closer to the outer peripheral side than the frame material edge portion, but it is not necessary to be limited to this. In particular, for double-groove sliding windows, from the viewpoint of opening and closing operability, it is preferably set as a structure in which the frame material protrudes from the main viewing surface of the frame body to the indoor side.

[0107] As described above, the door and window of the present invention is constructed by connecting frames with panels arranged inside in a state of being arranged side by side with each other. In at least one of the frames, the first inner peripheral side edge portion of the profile supporting the edge portion of the surface facing the outdoor of the panel, and the second inner peripheral side edge portion of the profile supporting the edge portion of the surface facing the indoor of the panel, are respectively arranged at the following positions in the depth direction, that is, the position is the same as the frame material edge portion of the main viewing surface facing the indoor of the frame material, which is located on the inner peripheral side, or is closer to the outer peripheral side than the frame material edge portion. The frame materials adjacent to each other in the frame are respectively provided with locking pieces, which extend from the opposite depth surfaces in the direction of the main viewing surface, then bend and extend in the depth direction. The adjacent frame materials are prevented from moving in directions away from each other by locking the locking piece provided on one frame material with the locking piece provided on the other frame material between the locking piece provided on the one frame material and the depth surface.

[0108] According to the present invention, by engaging the engaging pieces along the depth direction, adjacent frames can be prevented from moving in directions away from each other, so that the frames arranged side by side can be connected to each other without the need for longitudinal or middle stile components, and the increase in manufacturing cost and external dimensions can be suppressed. In addition, the frames arranged side by side do not need to be left and right, and can be similarly applied when they are arranged side by side up and down.

[0109] In addition, in the above-mentioned doors and windows of the present invention, the locking piece is arranged at a portion of the frame body that is closer to the indoor side than the edge portion located on the outdoor side, and a recess for filling a sealing material is provided at a portion of the locking piece facing the outdoor side between the one frame material and the other frame material.

[0110] According to the present invention, by filling the concave portion with a sealing material, it is possible to prevent water or air from flowing between the frames and between the indoor and outdoor areas, which is advantageous in terms of water tightness and air tightness.

[0111] In the above-mentioned door and window of the present invention, the one frame member and the other frame member each have a flat plate-shaped base wall portion extending in the depth direction, and are connected to each other in a state where the depth surfaces of the outer peripheral sides of the base wall portions face each other.

[0112] According to the present invention, there are advantages such as being able to simplify the shape of the outer peripheral surface of the frame, facilitating the engagement work of the engagement piece, and the like.

[0113] In addition, in the above-mentioned doors and windows of the present invention, in one of the frames, an adjustment gap is ensured between the depth surface on the inner peripheral side of the base wall portion of the frame material and the depth surface on the outer peripheral side of the depth wall portion in the frame material supporting the panel and opposite to the outer peripheral surface of the panel.

[0114] According to the present invention, when the frames are arranged vertically side by side, the positions of the adjustment gaps can be aligned, which is preferable in terms of appearance quality.

[0115] In addition, in the above-mentioned doors and windows of the present invention, the locking piece is arranged at a portion of the frame body that is closer to the indoor side than the edge portion located at the outdoor side, and between the one frame material and the other frame material, a recess for filling a sealing material is provided at a portion of the locking piece facing the outdoor side, and a dimension of the adjustment gap along the main viewing surface direction is configured to be larger than a dimension of the recess along the main viewing surface direction, and frames having the adjustment gap are respectively connected to both sides of a single frame body via the one frame material.

[0116] According to the present invention, by providing the frames having the recessed portions and the adjustment gaps of different sizes on both sides of a single frame, a door or window having an overall symmetrical shape can be formed, which is advantageous in terms of appearance quality.

[0117] In addition, in the above-mentioned doors and windows of the present invention, in the one frame material and the other frame material, overlapping pieces overlapping each other in the depth direction are respectively provided in the parts located closer to the indoor side than the locking piece, and at least one of the overlapping pieces is provided with a specified surface, and the specified surface abuts against the depth surface of the frame material on which the other overlapping piece is provided.

[0118] According to the present invention, by making the predetermined surface of the superimposed sheet contact the deep surface of the frame material, the dimensions of the frame body after the connection can be accurately determined.

[0119] In the above-mentioned door and window of the present invention, the overlapping piece is provided with a fitting portion, and the fitting portion restricts the relative movement of the overlapping piece in the depth direction by fitting when the specified surface abuts against the depth surface of the frame material provided with another overlapping piece.

[0120] According to the present invention, since the relative movement is restricted by fitting the fitting portions of the superimposed sheets, there is an advantage that the frame connection work can be easily performed.

[0121] In the above-mentioned door and window of the present invention, the frame bodies are arranged side by side on the left and right and are connected to each other via adjacent vertical frames.

[0122] According to the present invention, a transversely connected window having the above-mentioned advantages can be constructed.
