Description

[[Technical Field]]

[0001] The present invention relates to a fitting having a hollow portion in a profile that constitutes a frame body, and a reinforcing member disposed in the hollow portion of the profile. [[Background Art]]

[0002] Some fittings have a hollow portion in a profile that constitutes a frame body, and a reinforcing member is disposed in this hollow portion. The reinforcing member has a longitudinal dimension equivalent to that of the profile, and is fixed to the profile, for example, by attaching a fixing member such as a screw member from a portion constituting the face side of the profile (see, for example, Patent Document 1). [[Prior Art Literature]] [[Patent Literature]]

[0003] [[Patent Document 1]] Japanese Unexamined Patent Application Publication No. 2021-123973 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] By the way, the above-mentioned reinforcing member is inserted from the end of the profile and disposed in the hollow portion. For this reason, when workability during insertion is taken into consideration, it is preferable to configure the reinforcing member such that its dimensions ensure a gap between the reinforcing member and the profile. However, in the case of a reinforcing member that has a gap secured between itself and the profile, there is a concern that this may lead to a situation where the work of attaching the fixing member from the profile becomes complicated.

[0005] In view of the above circumstances, an object of the present invention is to provide a fitting that can facilitate the insertion work into a profile without complicating the fixing work to the profile. [[Means for Solving the Problem]]

[0006] To achieve the above objective, the joinery according to the present invention is characterized in that the frame has a hollow portion in the profiled material, and a reinforcing material is disposed in the hollow portion of the profiled material, and a movement restricting member is disposed between the reinforcing material and the profiled material to restrict relative movement along the depth direction. [Effects of the Invention]

[0007] According to the present invention, even when a gap is secured between the profile and the reinforcing material to facilitate insertion into the profile, relative movement along the projection direction can be restricted by arranging a movement restricting member, thereby preventing the work of attaching the fastener from becoming complicated.

[Modes for carrying out the invention]

[0009] The following describes in detail preferred embodiments of the joinery according to the present invention with reference to the attached drawings. For convenience, the terms "depth direction" and "face direction" may be used in the following description. The depth direction is the direction along the depth of the joinery, as indicated by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The face direction is the direction along the vertical direction perpendicular to the depth direction, in the case of a frame that extends horizontally, such as a bottom frame. In the case of a frame that extends vertically, such as a vertical frame, the face direction is the direction along the horizontal direction perpendicular to the depth direction. The surface along the face direction may be referred to as the face surface.

[0010] Figures 1 and 2 show a joinery that is an embodiment of the present invention. The joinery illustrated here is called a stepped window, having an upper sliding window and a lower fixed window inside a single frame 10, and is particularly illustrated as a stepped window applicable to buildings such as office buildings. The frame 10 is constructed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13 around the perimeter, and by installing a transom (horizontal frame) 14 in the middle of the left and right vertical frames 13. The upper frame 11, lower frame 12, vertical frame 13, and transom 14 (hereinafter, when referring to these upper frame 11, lower frame 12, vertical frame 13, and transom 14 collectively, they are simply referred to as profiles 11, 12, 13, and 14) are each composed of metal frame parts 11M, 12M, 13M, and 14M, which are extruded profiles formed from a metal such as an aluminum alloy, and resin frame parts 11P, 12P, 13P, and 14P, which are extruded profiles formed from resin. The outer sash 20A and inner sash 20B are respectively slidably arranged in the area enclosed by the upper frame 11, transom 14, and the left and right vertical frames 13. The outer sash 20A and inner sash 20B are constructed by supporting panels 24 such as double-glazed glass inside the upper frame 21, lower frame 22, and left and right vertical frames 23, respectively. Although not explicitly shown in the diagram, the upper frame 21, lower frame 22, and left and right vertical frames 23 are each constructed with an exterior metal frame portion made of a metal such as an aluminum alloy and an interior resin frame portion made of resin. A fixed panel 24F, such as double-glazed glass, is supported in the area enclosed by the transom 14, the lower frame 12, and the left and right vertical frames 13. As is clear from the diagram, an interior screen door 27 is provided in the area enclosed by the frame 25 provided on the interior side of the upper frame 11 and the left and right vertical frames 13, and the frame attachment 26 fixed to the transom 14. The following will mainly describe the structure of the transom 14 as described above, and will also detail the characteristic features of the present invention.

[0011] As shown in Figures 2 to 4, the metal frame portion 14M of the transom 14 is integrally molded from the metal frame body 30, outer rail portion 31, inner rail portion 32, rail cover receiving portion 33, inner guide wall portion 34, outdoor rail portion 35, outer panel support portion 36, inner panel support portion 37, upper engaging piece 38, and lower engaging base portion 39.

[0012] The metal frame body 30 constitutes a hollow section 30a with an irregular cross-section, surrounded by a lower wall section 130, an exterior wall section 230, an interior wall section 330, and an upper wall section 430. The lower wall section 130 extends along the depth direction, and the half located on the interior side is set to be one step lower than the half located on the exterior side. The interior and exterior halves of the lower wall section 130 each extend almost horizontally. On the upper surface of the lower wall section 130, a first screw hole B1 and a second screw hole B2 are provided in the exterior half and the interior half, respectively. The exterior wall section 230 and the interior wall section 330 extend almost vertically upward from the exterior edge and interior edge of the lower wall section 130. The extension dimension of the exterior wall section 230 is set to be smaller than the extension dimension of the interior wall section 330. The upper wall section 430 is provided between the upper edge of the exterior wall section 230 and the upper edge of the interior wall section 330. More specifically, the upper wall section 430 has a first constituent wall 430a, a second constituent wall 430b, a third constituent wall 430c, a fourth constituent wall 430d, a fifth constituent wall 430e, a sixth constituent wall 430f, and a seventh constituent wall 430g. The first constituent wall 430a extends almost horizontally toward the interior. The second constituent wall 430b extends almost vertically upward from the interior edge of the first constituent wall 430a. The third constituent wall 430c extends almost horizontally toward the interior from the upper edge of the second constituent wall 430b. On the lower surface of the third constituent wall 430c, a third screw hole B3 and a fourth screw hole B4 are provided in the exterior and interior portions, respectively. The fourth structural wall 430d extends inclined from the interior edge of the third structural wall 430c toward the interior, gradually becoming upward. The fifth structural wall 430e extends almost horizontally toward the interior from the interior edge of the fourth structural wall 430d. The sixth structural wall 430f extends almost vertically toward the interior from the interior edge of the fifth structural wall 430e. The seventh structural wall 430g connects to the upper edge of the interior wall section 330 by extending almost horizontally toward the interior from the upper edge of the sixth structural wall 430f. Between the lower part of the sixth structural wall 430f and the interior wall, a connecting wall section 530 is provided, extending almost horizontally to connect them. A fifth screw hole B5 is provided in the inner corner between the lower surface of the connecting wall section 530 and the sixth structural wall 430f.

[0013] The outer rail portion 31 extends substantially vertically upward from a portion located on the outdoor side of the third constituent wall 430c. This outer rail portion 31 guides sliding of the outer sliding screen 20A between itself and the upper rail portion 11a provided on the metal frame portion 11M of the upper frame 11. The inner rail portion 32 extends substantially vertically upward from the upper edge of the sixth constituent wall 430f. This inner rail portion 32 guides sliding of the inner sliding screen 20B between itself and the sliding screen accommodating portion 11b provided on the metal frame portion 11M of the upper frame 11.

[0014] The rail cover receiving portion 33 extends substantially horizontally toward the outdoor side from the upper edge portion of the sixth constituent wall 430f. The extension dimension of the rail cover receiving portion 33 is set to be close to the visible surface of the lower rail 22 facing the indoor side when the outer sliding screen 20A is arranged on the outer rail portion 31. A sealing member S1 is attached to the extending edge portion of the rail cover receiving portion 33 toward the outdoor side.

[0015] The inner guide wall portion 34 extends substantially vertically upward from the upper edge of the indoor wall portion 330. A sealing member S2 is attached to a portion facing the outdoor side at the upper edge portion of the inner guide wall portion 34.

[0016] The outdoor rail portion 35 extends slightly toward the outdoor side substantially horizontally from the upper edge of the outdoor wall portion 230, and then extends substantially vertically upward. The upward extension dimension of the outdoor rail portion 35 is set to be substantially the same as the upper edge of the second constituent wall 430b.

[0017] The outer panel support portion 36 extends substantially vertically downward from the lower edge of the outdoor wall portion 230. An outer pocket portion 36a is provided at a portion facing the room on the extending edge of the outer panel support portion 36. The inner panel support portion 37 extends substantially vertically downward from a position substantially in the middle of the depth direction on the lower wall portion 130. The outer panel support portion 36 and the inner panel support portion 37 are provided so as to face each other with a gap larger than the plate thickness of the FIX panel 24F secured therebetween. An inner pocket portion 37a and a cover engaging piece 37b are provided at a portion facing the outdoor on the extending edge of the inner panel support portion 37. A sixth screw hole B6 is provided in the internal corner between the viewing surface facing the room of the inner panel support portion 37 and the lower surface of the lower wall portion 130.

[0018] The upper engaging piece 38 extends substantially horizontally toward the room from a portion facing the room at the upper edge of the indoor wall portion 330, and then extends substantially vertically upward, and forms an upper fitting groove 38a between itself and the inner guide wall portion 34. The lower engaging base portion 39 extends substantially horizontally toward the room from the lower edge of the indoor wall portion 330. Engaging pieces 39a and 39b are provided on the lower surface of the lower engaging base portion 39 so as to protrude downward to the indoor side and the outdoor side respectively, and a lower fitting groove 39c is formed between the engaging pieces 39a and 39b.

[0019] The resin frame portion 14P of the transom 14 has an upper resin frame portion 14P1 provided at a portion on the indoor side in the upper part of the metal frame portion 14M, and a lower resin frame portion 14P2 provided at a portion on the indoor side in the lower part of the metal frame portion 14M.

[0020] The upper resin frame portion 14P1 is formed by integrally molding a resin frame main body 40 and an upper fitting fin portion 41. The resin frame main body 40 extends substantially horizontally along the depth direction. The upper fitting fin portion 41 extends downward in the width direction from a portion on the outdoor side on the lower surface of the resin frame main body 40. The upper resin frame portion 14P1 has the upper fitting fin portion 41 fitted into the upper fitting groove 38a, thereby being attached to the metal frame portion 14M.

[0021] The lower resin frame portion 14P2 covers the portion of the metal frame portion 14M that is on the indoor side of the inner panel support portion 37, and has a rectangular tube portion 50, an outer cover piece portion 51, an inner fitting fin portion 52, and a mounting plate portion 53. The rectangular tube portion 50 has a horizontally elongated rectangular cross-section and is hollow. In the illustrated example, a reinforcing rib 50a is provided in the middle portion, running vertically. The outer cover piece portion 51 engages with the inner panel support portion 37 via a cover engagement piece 37b, and extends almost horizontally outwards from the lower corner on the outdoor side of the rectangular tube portion 50, then bends upward, and then bends further inwards. The upper surface of this outer cover piece portion 51 is provided with an outer projection 51a that protrudes upward from the portion on the outdoor side. The outer projection 51a abuts against the lower surface of the cover engagement piece 37b when the outer cover piece portion 51 is engaged with the cover engagement piece 37b. The internal fitting fin portion 52 fits into the lower fitting groove 39c of the metal frame portion 14M and extends almost vertically upward from the upper corner on the indoor side of the rectangular tube portion 50. The mounting plate portion 53 extends almost horizontally into the room from the upper part on the indoor side of the rectangular tube portion 50. This lower resin frame portion 14P2 is attached to the metal frame portion 14M by engaging the outer cover piece portion 51 with the cover engaging piece 37b and fitting the internal fitting fin portion 52 into the lower fitting groove 39c.

[0022] The transom 14 described above is provided with reinforcing members 60, auxiliary reinforcing members 70, and transom attachments 80. The reinforcing members 60 and auxiliary reinforcing members 70 are made of a metal such as stainless steel that has rigidity equal to or greater than that of the aluminum alloy or other metal constituting the metal frame portion 14M, and a smaller coefficient of linear expansion than that of the aluminum alloy or other metal.

[0023] As shown in Figures 5(a), 6 to 8, the reinforcing member 60 is positioned in the hollow portion 30a of the metal frame body 30 of the transom 14, and has a reinforcing base 61 and two mounting pieces 62. The reinforcing base 61 is composed of a first plate portion 61a, a second plate portion 61b, a third plate portion 61c, a fourth plate portion 61d, and a fifth plate portion 61e. The dimensions of the reinforcing base 61 along the left and right sides are slightly smaller than the dimensions along the longitudinal side of the metal frame body 30. The first plate portion 61a is a flat plate that extends almost vertically along the top and bottom. The dimensions of the first plate portion 61a along the top and bottom are smaller than the dimensions along the top and bottom from the upper end of the second screw hole B2 to the lower surface of the connecting wall portion 530. The second plate portion 61b is a flat plate that extends almost horizontally from the lower edge of the first plate portion 61a toward the outside. The dimensions of the second plate section 61b along the depth direction are smaller than the dimensions along the depth direction from the exterior surface of the interior wall section 330 to the interior end of the fourth screw hole B4. The third plate section 61c is a flat plate that extends almost vertically upward from the exterior edge of the second plate section 61b. The dimensions of the third plate section 61c along the top and bottom are smaller than the dimensions from the upper end of the second screw hole B2 to the lower end of the fourth screw hole B4. The fourth plate section 61d is a flat plate that extends almost horizontally outward from the upper edge of the third plate section 61c. The dimensions of the fourth plate section 61d along the depth direction are smaller than the third constituent wall 430c. The fifth plate section 61e is a flat plate that extends almost vertically downward from the exterior edge of the fourth plate section 61d. The vertical dimension of the fifth plate portion 61e is smaller than the vertical dimension from the lower end of the third screw hole B3 to the upper end of the first screw hole B1, and is also smaller than the vertical dimension of the third plate portion 61c. Furthermore, the dimension in the depth direction from the indoor-facing surface of the first plate portion 61a to the outdoor-facing surface of the fifth plate portion 61e is smaller than the dimension in the depth direction from the outdoor wall portion 230 to the second constituent wall 430b in the hollow portion 30a. The mounting piece portion 62 is a flat plate shape that extends almost vertically upward from both side edges of the second plate portion 61b. The vertical dimension of the mounting piece is smaller than the vertical dimension of the third plate portion 61c.

[0024] The reinforcing member 60 is fixed to the metal frame portion 14M of the transom 14 by inserting the metal frame portion 14M into the hollow portion 30a of the metal frame body 30 in its standalone state, and then screwing a screw member (fixing device) N1 into the first plate portion 61a via the interior wall portion 330. As shown in Figure 3, in this embodiment, the screw members N1 are screwed only into both ends of the first plate portion 61a. Here, in the above-described reinforcing member 60, the external dimensions are made smaller than the internal dimensions of the hollow portion 30a, making it possible to easily insert it into the hollow portion 30a. However, in this state, the reinforcing member 60 can move in the depth direction and up and down inside the hollow portion 30a. For example, as shown in Figure 9(a), if the metal frame portion 14M is rotated 90° so that the interior wall portion 330 is at the top, the interior wall portion 330 and the first plate portion 61a of the reinforcing member 60 become separated. In order to screw in the aforementioned screw member N1, the metal frame portion 14M must be positioned in this orientation. This may complicate the process of screwing the screw member N1 into the first plate portion 61a via the interior wall portion 330. Therefore, in this embodiment, as shown in Figure 9(b), the above problem is solved by interposing a movement restricting member 90 between the metal frame portion 14M and the reinforcing material 60.

[0025] In other words, the movement restricting member 90 is formed from thermal insulation material and, as shown in Figures 5(b), 6 to 8, has a first block portion 90a, a connecting piece portion 90b, and a second block portion 90c. The first block portion 90a is shaped like a rectangular parallelepiped. The dimension of the first block portion 90a along the depth direction is smaller than the gap that is created between the fifth plate portion 61e and the exterior wall portion 230 when the first plate portion 61a is brought into contact with the interior wall portion 330, and the dimension of the first block portion 90a along the top and bottom is set to be smaller than the dimension along the top and bottom between the first constituent wall 430a and the lower wall portion 130. The connecting piece 90b is a flat plate with a thickness corresponding to the gap created between the second constituent wall 430b and the fifth plate 61e when the first plate 61a is brought into contact with the interior wall 330, and extends almost vertically upward from the edge on the interior side of the upper surface of the first block 90a. The second block 90c is a rectangular parallelepiped provided on the upper edge of the connecting piece 90b. The dimensions of the second block 90c along the depth direction are approximately the same as the dimensions between the second constituent wall 430b and the third screw hole B3, and the dimensions of the second block 90c along the top and bottom are set to be slightly larger than the protruding dimension of the third screw hole B3. The position in which the second block 90c is provided is set so that it is interposed between the second constituent wall 430b and the third screw hole B3 when the upper end surface of the first block 90a is brought into contact with the lower surface of the first constituent wall 430a.

[0026] The movement restricting members 90 are interposed between the metal frame portion 14M and the reinforcing member 60 at both ends. When the movement restricting members 90 are interposed, the first plate portion 61a of the reinforcing member 60 remains in contact with the interior wall portion 330 and the second plate portion 61b remains in contact with the upper end of the second screw hole B2, regardless of the orientation of the metal frame portion 14M. In other words, by interposing the movement restricting members 90, relative movement of the reinforcing member 60 along the depth direction and relative movement along the visibility direction with respect to the metal frame portion 14M are both prevented. As a result, even when the metal frame portion 14M is rotated 90° so that the interior wall portion 330 is facing upward, as shown in Figure 9(b), the contact between the interior wall portion 330 and the first plate portion 61a of the reinforcing member 60 is maintained, making it easy to screw in the screw member N1. Furthermore, since the movement restricting member 90 is formed from thermal insulation material, it is possible to suppress heat transfer in the depth direction in the transom 14, and there is no risk of impairing thermal insulation.

[0027] The metal frame portion 14M of the transom 14 described above is placed between the left and right vertical frames 13 with the reinforcing material 60 positioned in the hollow portion 30a, and screw members (not shown) are screwed into the screw holes B1 to B6 via the metal frame portion 13M of the vertical frame 13, thereby forming the frame body 10 together with the upper frame 11 and the lower frame 12. Furthermore, as shown in Figure 10, the reinforcing material 60 is fixed to the metal frame portion 13M of the vertical frame 13 by screwing a screw member N2 into the mounting piece 62 via the metal frame portion 13M of the vertical frame 13.

[0028] As shown in Figures 5(c) and 6-8, the auxiliary reinforcing member 70 is attached to the interior wall portion 330 facing the interior of the metal frame body 30 of the transom 14, and has an auxiliary base portion 70a and two reinforcing plate portions 70b. The auxiliary base portion 70a is a flat plate that extends vertically. The vertical dimension of the auxiliary base portion 70a is smaller than the vertical dimension from the upper engaging piece 38 to the lower engaging base portion 39 in the interior wall portion 330. The longitudinal dimension of the auxiliary base portion 70a is set to a length that can be positioned between the two screw members N1 used when fixing the reinforcing member 60. As shown in Figure 3, the auxiliary base portion 70a is provided with a plurality of notches 70c along its longitudinal direction. The notches 70c are rectangular through holes and are arranged side by side at equal intervals. The reinforcing plate portion 70b extends almost horizontally from both the upper and lower edges of the auxiliary base portion 70a toward the interior, then curves toward a direction toward proximity to each other and extends almost vertically. A gap of a size sufficient to expose the notch 70c of the auxiliary base portion 70a toward the interior is secured between the curved portions of the auxiliary base portion 70a.

[0029] As shown in Figures 3, 6 to 8, the auxiliary reinforcing member 70 is fixed to the metal frame 14M by screwing a screw member (auxiliary fastener) N3 into the interior wall 330 via an auxiliary base 70a, while the auxiliary reinforcing member 70 is in contact with the interior wall 330 at positions between the screw members N1 on the interior-facing surface of the interior wall 330. The screw members N3 are screwed into both ends of the auxiliary reinforcing member 70 and at positions between the notches 70c. As shown in Figure 7, a screw insertion hole 63 is formed in the first plate portion 61a of the reinforcing member 60 in the portion corresponding to the screw member N3 for fixing the auxiliary reinforcing member 70. In other words, the screw member N3 for fixing the auxiliary reinforcing member 70 is screwed only into the interior wall 330 of the metal frame 14M, and does not screw into the reinforcing member 60 but passes through the screw insertion hole 63.

[0030] As shown in Figure 2, the transom attachment 80 is interposed between the frame attachment 26 and the metal frame portion 14M of the transom 14, and is used to fix the frame attachment 26 to the metal frame portion 14M. The transom attachment 80 in this embodiment is an extruded profile formed from a metal such as an aluminum alloy, and as shown in Figures 5(d), 6 to 8, it has an attachment base plate portion 81, an upper support piece portion 82, and a lower support piece portion 83. The attachment base plate portion 81 has a first base plate 81a, a second base plate 81b, a third base plate 81c, a fourth base plate 81d, and a fifth base plate 81e. The first base plate 81a is a flat plate that extends almost vertically along the vertical direction, and is formed to a size that allows it to be inserted between the reinforcing plate portions 70b provided on the auxiliary reinforcing member 70. A seating member 100 is attached to the surface of the first base plate 81a that is located on the outdoor side. The seating member 100 is a block-shaped piece formed from thermal insulation material and is attached to the first base plate 81a via engaging fins 81f provided on the first base plate 81a. The dimensions of the seating member 100 along the depth direction are set so that when it is brought into contact with the interior-facing surface of the interior wall portion 330, the first base plate 81a is located on the interior side of the bent portion of the reinforcing plate portion 70b. The second base plate 81b is a flat plate that extends almost horizontally inward from the upper edge of the first base plate 81a. The dimensions of the second base plate 81b along the depth direction are set so that when the seating member 100 is brought into contact with the interior-facing surface of the interior wall portion 330, it protrudes inward from the bent portion of the reinforcing plate portion 70b. The third base plate 81c extends almost vertically upward from the interior-side edge of the second base plate 81b. The fourth substrate 81d extends almost horizontally from the lower edge of the first substrate 81a toward the interior. The dimension of the fourth substrate 81d along the depth direction is smaller than that of the second substrate 81b, and it is set to protrude toward the interior from the bent portion of the reinforcing plate 70b when the seating member 100 is brought into contact with the interior-facing surface of the interior wall portion 330. The fifth substrate 81e extends almost vertically downward from the interior-facing edge of the fourth substrate 81d. The dimension of the fifth substrate 81e along the top and bottom is approximately the same as the dimension of the third substrate 81c along the top and bottom.As shown in Figure 2, the vertical dimension from the lower edge of the fifth substrate 81e to the upper edge of the third substrate 81c is approximately equal to the distance between the resin frame body 40 of the upper resin frame portion 14P1 and the mounting plate portion 53 of the lower resin frame portion 14P2 in the resin frame portion 14P of the transom 14. The lower part of the fifth substrate 81e, on the surface facing the room, is provided with a lower engagement receiving portion for engaging the lower engaging fin portion 26a of the picture frame attachment 26.

[0031] As shown in Figures 2 and 5(d), the upper support piece 82 extends outward from the upper edge of the third substrate 81c. The extension dimension of the upper support piece 82 is set to be slightly larger than the extension dimension of the second substrate 81b. An upper engagement groove 82a is provided on the upper surface of the upper support piece 82 for engaging with the upper engaging fin portion 26b of the frame attachment 26. A connecting substrate 84 is provided between the upper support piece 82 and the second substrate 81b, and is approximately vertical in the vertical direction. The position where the connecting substrate 84 is provided is on the extension of the fifth substrate 81e.

[0032] The lower support piece 83 extends from the lower edge of the fifth substrate 81e toward the outside. The extension dimension of the lower support piece 83 is set so that the position of the outer edge is approximately the same as the outer edge of the upper support piece 82.

[0033] As shown in Figures 2, 6 to 8, the transom attachment 80 is fixed to the metal frame portion 14M of the transom 14 by screwing a screw member N4 into the interior base plate via the first base plate 81a and the seating member 100, with the seating member 100 in contact with the interior wall portion 330 via the notch 70c of the auxiliary reinforcing member 70, and the upper support piece 82 and lower support piece 83 positioned between the resin frame body 40 of the upper resin frame portion 14P1 and the mounting plate portion 53 of the lower resin frame portion 14P2. As shown in Figure 8, the first plate portion 61a of the reinforcing member 60 also has a screw insertion hole 64 in the portion corresponding to the screw member N4 for fixing the transom attachment 80. In other words, the screw member N4 for fixing the transom attachment 80 is screwed only into the interior wall portion 330 of the metal frame portion 14M, and passes through the reinforcing material 60 via the screw insertion hole 64 without being screwed into it. The transom attachment 80, which has been installed as described above, is fitted with the aforementioned frame attachment 26 by engaging the upper engaging fin portion 26b with the upper engaging groove 82a and engaging the lower engaging fin portion 26a with the lower engaging receiving portion.

[0034] In the embodiment described above, a reinforcing member 60 is provided on the transom 14 as an example, but it can also be similarly applied when the reinforcing member 60 is provided on other profiles such as the upper frame 11 and lower frame 12, etc. Also, when applied to the transom 14, a stepped window having an upper sliding window and a lower fixed window is given as an example, but it can of course also be applied to stepped windows with other types of windows. In this case, it is not necessary for the profiles to have resin frame parts 11P, 12P, 13P, 14P, nor is it necessary for the interior side to have an interior screen door 27.

[0035] Furthermore, while the above-described embodiment illustrates a movement-restricting member 90 formed from thermal insulation material, which is advantageous in terms of thermal insulation, the movement-restricting member does not necessarily have to be formed from thermal insulation material. The shape of the movement-restricting member 90 is also not limited to that of the embodiment. In addition, although the movement-restricting member 90 is provided on the outermost part of the reinforcing member 60, it may be provided on other parts as long as it can restrict relative movement in the depth direction between it and the profile. Furthermore, although the movement-restricting member 90 is provided on both ends of the reinforcing member 60, it is not necessarily limited to this, and may be provided at three or more locations including both ends, or it may be provided along the entire length of the reinforcing member 60.

[0036] Furthermore, since the ends of the reinforcing material 60 are fixed to the vertical frame 13, even if the horizontal frame such as the transom 14 is exposed to high temperatures such as a fire and melts or softens, it is possible to prevent it from falling off, which is advantageous in terms of fire resistance, but it is not necessarily limited to this.

[0037] As described above, the joinery according to the present invention is characterized in that the frame has a hollow portion in the profiled material, and a reinforcing material is disposed in the hollow portion of the profiled material, and a movement restricting member is disposed between the reinforcing material and the profiled material to restrict relative movement along the depth direction. According to this invention, even when a gap is secured between the profile and the reinforcing material to facilitate insertion into the profile, relative movement along the projection direction can be restricted by arranging a movement restricting member, thereby preventing the work of attaching the fastener from becoming complicated.

[0038] Furthermore, the present invention is characterized in that, in the above-described joinery, the reinforcing material is formed from metal, and the movement restricting member is formed from thermal insulation material. According to this invention, heat transfer along the depth direction can be suppressed by the movement restricting member, which is advantageous in terms of thermal insulation.

[0039] Furthermore, the present invention is characterized in that, in the above-described joinery, the frame is constructed by providing a horizontal frame having the hollow portion between the left and right vertical frames, and the reinforcing material and the movement restricting member are arranged in the hollow portion of the horizontal frame. According to this invention, the process of inserting reinforcing materials and attaching fasteners to horizontal frames such as transoms can be made easier.

[0040] Furthermore, the present invention is characterized in that, in the above-described joinery, the end of the reinforcing member is fixed to the vertical frame. According to this invention, it is possible to prevent the side frame from falling off even if it melts or softens at high temperatures.

[0041] Furthermore, the present invention is characterized in that, in the above-described joinery, the reinforcing member is fixed to the horizontal frame by providing a fastener through a portion that extends vertically on the interior side of the horizontal frame. According to this invention, the reinforcing material is fixed to the horizontal frame via a fastener that extends vertically on the indoor side of the horizontal frame, thereby suppressing the amount of thermal expansion in the longitudinal direction of the horizontal member and the reinforcing material.

[0042] Furthermore, the present invention is characterized in that, in the above-described joinery, the movement restricting member is interposed between the portion of the horizontal frame that extends vertically on the exterior side and the reinforcing material. According to this invention, it is possible to attach the fastener while the reinforcing material is in contact with the portion of the horizontal frame located on the interior side.

[0043] Furthermore, the present invention is characterized in that, in the above-described joinery, an auxiliary reinforcing member is provided on the visible surface of the horizontal frame facing the interior side, and the auxiliary fastener for fixing the auxiliary reinforcing member is attached to the horizontal frame in a state in which it is not attached to the reinforcing member. According to this invention, the reinforcing material and auxiliary reinforcing material are fixed to the profile by individual fasteners and auxiliary fasteners. [Explanation of symbols]
