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 are formed by connecting vertical frames of frame bodies arranged side by side to each other (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent Publication No. 7-116888 Summary of the invention

[0004] However, in recent years, doors and windows require larger openings, in other words, the main surface of the frame material is required to be thinner. That is, if the size of the frame material along the main surface is reduced, the glass opening can be increased accordingly. However, when the apparent size of the frame material is reduced, the cross-sectional performance will be reduced. In particular, doors and windows set up at high places such as buildings often bear greater wind pressure, and if wind pressure resistance is considered, it may not be considered to be preferred.

[0005] In view of the above-mentioned actual situation, the present invention aims to provide a door and window that can achieve a larger opening while ensuring wind pressure resistance.

[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. Among the frame materials adjacent to each other in the frame, a reinforcement is provided on the main viewing surface facing the indoor of at least one.

[0007] According to the present invention, since a reinforcement member is provided on the main surface of the frame material facing indoors, the cross-sectional performance can be improved without increasing the dimension in the main surface direction, and a larger opening can be achieved while ensuring wind pressure resistance.

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.

[0046] 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.

[0047] 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.

[0048] 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. The protruding dimension of the inner main viewing wall portion 14c of the outer frame to the inner peripheral side is approximately equal to the protruding dimension of the outer door stop wall portion 14b.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 portion 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 portion 15a. In addition, the protruding dimension L1 of the engaging legs 16d and the fixing legs 16e is set in a manner substantially the same as the gap d1 that is to be ensured between the depth surface of the inner peripheral side of the inner base wall portion 15a in the upper frame 10A and the depth surface of the outer peripheral side of the portion 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 dimension of the longitudinal inner panel clamping plate portion 16b from the strip base plate portion 16a is 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.

[0055] 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.

[0056] 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 dimensions 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 dimensions and extend on the same straight line, which is advantageous in terms of appearance quality when observed from the outdoor side.

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.

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.

[0059] 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.

[0061] 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.

[0062] 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, the following state is achieved: the extended end surface (prescribed 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.

[0063] 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.

[0064] Door and window structure

[0065] 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, if the screw member B1 is screwed to the inner overlapping piece 15j via the longitudinal overlapping piece 44j from this state, the first longitudinal connecting window W1 and the second longitudinal connecting window W2 can be connected to each other in a state where the dimensions along the main viewing surface direction are 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 manufacturing cost and the increase in the outer dimensions can be suppressed. Figure 6 , Figure 7 As shown, in the longitudinal overlapping piece 44j, the part where the screw member B1 is screwed is provided with a recess 44n capable of accommodating the head of the screw member B1. Therefore, the head of the screw member B1 does not protrude from the main viewing surface of the longitudinal inner main viewing wall portion 44b facing the room to the indoor side.

[0066] Furthermore, in the door and window, a reinforcement member 50 and a cover member 51 are provided in the portion exposed to the indoor side and spanning the first inner longitudinal frame 15 and the second longitudinal frame 44. The reinforcement member 50 is formed of a metal such as an aluminum alloy, steel, or stainless steel, and is provided to span the entire length of the first inner longitudinal frame 15 and the second longitudinal frame 44 along the longitudinal direction. In the embodiment, a reinforcement member 50 having a reinforcement base 50a, a depth extension portion 50b, and an appearance extension portion 50c is applied. The reinforcement base 50a is in the shape of a flat plate, and its width corresponds to the mutual spacing between the inner locking protrusion 15f and the longitudinal locking protrusion 44d. The depth extension portion 50b extends from one edge of the reinforcement base 50a toward the indoor side in the depth direction. The appearance extension portion 50c extends from the extension edge of the depth extension portion 50b toward the direction opposite to the reinforcement base 50a in the main viewing direction. The reinforcement member 50 is fixed to the second longitudinal frame 44 by screwing the mounting screw 53 through the reinforcement base 50a to the longitudinal inner main wall portion 44b in a state where the reinforcement base 50a is in contact with both the main surface of the inner frame inner main wall portion 15c facing the room and the main surface of the longitudinal inner main wall portion 44b facing the room. The cover member 51 is in the shape of an angular column, one side of which is open and has a length substantially equal to the total length of the first inner longitudinal frame 15 and the second longitudinal frame 44 along the longitudinal direction, and is formed to a size capable of accommodating the reinforcement member 50 inside. The cover member 51 is installed at a portion spanning the first inner longitudinal frame 15 and the second longitudinal frame 44 via the inner locking protrusion 15f and the longitudinal locking protrusion 44d.

[0067] According to the door and window provided with the reinforcement member 50 in the above manner, the cross-sectional performance of the first inner longitudinal frame 15 and the second longitudinal frame 44 is improved by providing the reinforcement member 50. Therefore, even when the dimensions of the first inner longitudinal frame 15 and the second longitudinal frame 44 along the main viewing surface direction are set small in order to seek a larger opening, sufficient rigidity can be ensured. This has the following advantages: even when it is installed in a high place such as a building, there is no need to worry about the central part of the first inner longitudinal frame 15 and the second longitudinal frame 44 along the longitudinal direction being deformed, such as bulging indoors or outdoors, due to the outdoor wind pressure applied to the panels 24, P1, P2, and P3.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] In addition, in the above-mentioned embodiment, the protrusion dimension of the inner engaging piece 15i from the first inner longitudinal frame 15 is larger than the protrusion dimension of the longitudinal engaging piece 44i from the second longitudinal frame 44, but it is also possible to configure the protrusion dimension of the longitudinal engaging piece 44i from the second longitudinal frame 44 to be larger than the protrusion dimension of the inner engaging piece 15i from the first inner longitudinal frame 15. In addition, although the example of connecting a plurality of longitudinal connecting windows W1 and W2 left and right is shown, the connected frame body does not need to be a longitudinal connecting window. Furthermore, although the example of connecting the left and right frames is shown, it can also be connected up and down. Furthermore, although the example of the door window with the screen 30 is shown, it is not necessary to have the screen.

[0072] Modifications

[0073] In the above embodiment, the reinforcement member 50 includes a reinforcement base 50a, a depth extension portion 50b, and an appearance extension portion 50c, and the reinforcement base 50a is provided so as to span the first inner longitudinal frame 15 and the second longitudinal frame 44, but the shape of the reinforcement member is not limited thereto. Fig. 9 Modification 1 shown or Fig.10 As shown in the second modification, separate reinforcement members are provided on the first inner longitudinal frame 15 and the second longitudinal frame 44. Fig. 9In the modification 1, two reinforcement members 54 having a reinforcement base 54a, a depth extension portion 54b, and an appearance extension portion 54c are prepared, and the mounting screw 53 is screwed to the inner frame inner main visual wall portion 15c of the first inner longitudinal frame 15 via the reinforcement base 54a of one reinforcement member 54. Similarly, regarding the other reinforcement member 54, the mounting screw 53 is screwed to the longitudinal inner main visual wall portion 44b of the second longitudinal frame 44 via the reinforcement base 54a. In addition, back plates 56 are respectively provided on the inner side of the inner locking protrusion 15f and the longitudinal locking protrusion 44d, and the reinforcement screw 55 is reinforced and screwed to the back plate 56 via the cover member 51, thereby clamping the inner locking protrusion 15f and the longitudinal locking protrusion 44d between the cover member 51 and the back plate 56.

[0074] In addition, Fig.10 In the second modification, two reinforcing members 57 having a reinforcing base 57a, a depth extension 57b, and an appearance extension 57c are prepared, and the reinforcing base 57a of one reinforcing member 57 is brought into contact with the inner frame inner main visual wall 15c of the first inner longitudinal frame 15, and from this state, the mounting screw 53 is screwed into the depth extension 57b via the cover member 51, thereby clamping the inner locking protrusion 15f between the cover member 51 and the depth extension 57b. Similarly, the reinforcing base 57a of the other reinforcing member 57 is brought into contact with the longitudinal inner main visual wall 44b of the second longitudinal frame 44, and from this state, the mounting screw 53 is screwed into the depth extension 57b via the cover member 51, thereby clamping the longitudinal locking protrusion 44d between the cover member 51 and the depth extension 57b.

[0075] 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 pressure edge 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 pressure edge of the surface facing the indoor 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 indoor, or is closer to the outer peripheral side than the frame material edge portion, but it is not necessary to be limited to this. Especially for double-groove sliding windows, from the viewpoint of opening and closing operability, it is preferably set to a structure in which the frame material protrudes from the main viewing surface of the frame body to the indoor side. In addition, although the reinforcement is provided in the two longitudinal frames, it is sufficient to be provided in at least one longitudinal frame, and the cover component is not necessary.

[0076] As described above, the doors and windows of the present invention are 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, a first inner peripheral side edge portion of a profile supporting an edge portion of a surface facing the outdoor of the panel and a second inner peripheral side edge portion of a profile supporting an edge portion of a surface facing the indoor of the panel are respectively arranged at the following positions in the depth direction, that is, the positions are the same as the frame material edge portion of the main viewing surface facing the indoor of the frame material and located on the inner peripheral side or are closer to the outer peripheral side than the frame material edge portion. In the frame materials adjacent to each other in the frame, a reinforcement is provided on the main viewing surface facing the indoor of at least one of them.

[0077] According to the present invention, since a reinforcement member is provided on the main surface of the frame material facing indoors, the cross-sectional performance can be improved without increasing the dimension in the main surface direction, and a larger opening can be achieved while ensuring wind pressure resistance.

[0078] Furthermore, in the above-mentioned door and window of the present invention, the reinforcing member is provided at a portion spanning across each of the adjacent frame materials, and is in contact with a front surface of each frame material facing the interior of the room.

[0079] According to the present invention, the cross-sectional performance of each of adjacent frame materials can be improved.

[0080] In addition, in the above-mentioned doors and windows of the present invention, the reinforcement member is constructed to have a reinforcement base and a depth extension portion, wherein the reinforcement base covers the main viewing surface of the frame material facing the interior, and the depth extension portion extends from the reinforcement base toward the interior along the depth direction.

[0081] According to the present invention, a profile having a reinforcement base portion and a depth-extending portion can be used as a reinforcement member, and therefore, an increase in weight can be suppressed.

[0082] Furthermore, in the above-mentioned door and window of the present invention, a cover member is provided on a portion of the frame material facing the interior of the room in a state of covering the reinforcement member.

[0083] According to the present invention, it is possible to prevent the reinforcement member from being exposed to the outside, and there is no concern about deterioration of the appearance quality.

[0084] In addition, in the above-mentioned doors and windows of the present invention, adjacent frame materials of the frame body are respectively provided with locking pieces, each of which extends from mutually opposite depth surfaces along the main viewing surface direction and then bends and extends along 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 and the depth surface with the locking piece provided on the other frame material.

[0085] 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.

[0086] 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, which abuts against the depth surface of the frame material on which the other overlapping piece is provided.

[0087] 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.

[0088] In the above-mentioned door and window of the present invention, the two overlapping pieces are provided with a fitting portion, and the fitting portion restricts the relative movement of the two overlapping pieces in the depth direction by fitting when the predetermined surface abuts against the depth surface of the frame material provided with the other overlapping piece.

[0089] According to the present invention, since the relative movement is restricted by fitting the fitting portions of the superimposed sheets, the frame body connection work and the cover member mounting work can be easily performed.

[0090] In the above-mentioned door and window of the present invention, the overlapping piece arranged on the indoor side is provided with a recessed portion facing the indoor side, and the mounting screws are screwed into the overlapping piece arranged on the outdoor side through the recessed portion of the overlapping piece.

[0091] According to the present invention, adjacent frame materials are firmly connected by being screwed with the superimposed sheets of the mounting screws. And the heads of the mounting screws do not protrude from the indoor front view of the frame material, and therefore, do not hinder the installation of the reinforcement.
