Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the fitting according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by this embodiment.

[0012] Hereinafter, for convenience, the terms "prospective direction" and "finding direction" may be used. The prospective direction (the direction indicated by arrow Z in the figure) is the indoor-outdoor direction along the depth of the fitting. The surface and wall along the prospective direction may be referred to as the prospective surface and prospective wall. The finding direction is the direction along the up and down perpendicular to the prospective direction (the direction indicated by arrow Y in the figure) in the case of those extending along the horizontal direction such as the upper frame, lower frame, upper sash, lower sash, etc., and is the direction along the horizontal perpendicular to the prospective direction (the direction indicated by arrow X in the figure) in the case of those extending along the vertical direction such as the vertical frame, vertical sash, etc. The surface and wall along the finding direction may be referred to as the finding surface and finding wall.

[0013] 〔Schematic configuration of fitting〕 FIG. 1 is a longitudinal sectional view of a fitting 10 according to an embodiment. FIG. 2 is a cross-sectional view of the fitting 10. However, since the fitting 10 is basically symmetric in shape, only the left side portion is shown in FIG. 2. The fitting 10 according to the present embodiment is a retrofit fitting in which a new frame 14 is provided on the inner peripheral side of an existing frame 12, and is what is called a FIX window in which a panel 16 such as laminated glass is held on the inner peripheral side of the new frame 14. In the fitting 10, the construction cost can be reduced by not removing the existing frame 12. Each frame member of the existing frame 12 is an extruded member made of a metal such as an aluminum alloy and is configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction. Also, the frame members of the new frame 14 are also extruded members and are configured to have a substantially uniform cross-sectional shape over the entire length, but are a composite material of a metal member on the outdoor side and a resin member on the indoor side.

[0014] The existing frame 12 is configured by surrounding the existing upper frame 18, the existing lower frame 20, and the left and right existing vertical frames 22. Also, the new frame 14 is configured by surrounding the new upper frame 24, the new lower frame 26, and the left and right new vertical frames 28. The new frame 14 has a vertical-dominant structure. Hereinafter, the configuration of the new frame 14 will be described sequentially for each frame member 24, 26, 28.

[0015] 〔Configuration of new vertical frame〕 The newly installed vertical frame 28 has an outdoor metal frame 30, a first resin frame 32 and a second resin frame 34 on the indoor side. The metal frame 30 corresponds to the metal member according to the present invention. Also, the first and second resin frames 32, 34 correspond to the resin members according to the present invention. An edge pressing 36 is attached to the newly installed vertical frame 28. The metal frame 30 has a hollow portion 30a on the outdoor side that is long in the prospecting direction, an outdoor finding portion 30b that protrudes toward the inner peripheral side, and a prospecting piece 30c that extends toward the indoor side. The tip of the outdoor finding portion 30b supports the edge of the outdoor surface of the panel 16 via a pocket portion and a bead 37.

[0016] The hollow portion 30a and the prospecting piece 30c have substantially the same length in the prospecting direction. Substantially all of the hollow portion 30a protrudes outside the existing vertical frame 22. On the inner peripheral side closer to the indoor side of the hollow portion 30a, a first engaging portion 30d and a second engaging portion 30e for engaging with the edge pressing 36 are provided. The first engaging portion 30d and the second engaging portion 30e are in an L shape protruding toward the side closer to each other. The first engaging portion 30d is on the outdoor side and the outer peripheral side of the second engaging portion 30e. On the indoor finding wall of the hollow portion 30a, a third engaging portion 30f for engaging with the first resin frame 32 is provided. At the end of the prospecting piece 30c, a fourth engaging portion 30g for engaging with the first resin frame 32 is provided. The prospecting piece 30c is fixed to the prospecting wall of the existing vertical frame 22 by screws (fasteners) 42 via a spacer 38 and a base member 40. The base member 40 extends to the indoor side and is fixed to the existing vertical frame 22 by screws 45. The base member 40 and the base members 54, 80 described later are made of an aluminum alloy material or a stainless steel material, etc., and are of high strength.

[0017] The first resin frame 32 has a hollow portion 32a that is elongated in the prospecting direction as a base, a prospecting piece 32b that protrudes outside, a relay piece 32c that protrudes inside, and an engaging piece 32d that protrudes on the outer peripheral side. An engaging piece 32e protrudes outside the hollow portion 32a. The tip of the prospecting piece 32b is bent and engages with the third engaging portion 30f. A screw insertion hole through which the screw 42 passes is formed in the prospecting piece 32b, but it is covered by the edge pressing 36 and not visible. The tip of the engaging piece 32d engages with the fourth engaging portion 30g.

[0018] The second resin frame 34 has an irregular L shape, and the short side portion of the L shape is screwed to the relay piece 32c. The long side portion of the L shape extends toward the outer peripheral side and closes the space between the existing frame 12 or the housing. A plurality of folding grooves 34a are provided in this L-shaped portion, and by folding any one of the folding grooves 34a, the distance from the existing frame 12 or the housing can be adjusted. A gap blocking member 43 is provided adjacent to the tip of the second resin frame 34. The second resin frame 34 functions as a frame.

[0019] 〔Configuration of the edge pressing member〕 The edge pressing member 36 includes a metal edge pressing member 44 on the outdoor side and a resin edge pressing member 46 on the indoor side. The metal edge pressing member 44 and the resin edge pressing member 46 are strongly engaged with each other at the engaging portions of L shape and square U shape. The metal edge pressing member 44 has a fixing piece 44a extending obliquely toward the outdoor side. The tip of the fixing piece 44a is engaged with the first engaging portion 30d, and the recess formed at the end is engaged with the second engaging portion 30e. The resin edge pressing member 46 has a substantially square cross section and is partitioned into two rooms arranged in the finding direction. From the indoor side of the resin edge pressing member 46, an engaging piece 46a protrudes toward the outer peripheral side and is engaged with the engaging piece 32e.

[0020] A part of each of the metal edge pressing member 44 and the resin edge pressing member 46 forms a finding portion 36a of the edge pressing member 36. The inner peripheral side end of the finding portion 36a supports the edge of the indoor surface of the panel 16 via the bead 37. A panel holding space 48 surrounded by the expected wall of the hollow portion 30a, the outdoor side finding portion 30b, and the finding portion 36a is formed. The finding portion 36a serves as the indoor side finding portion of the panel holding space 48. Note that the panel holding space 48 is formed to communicate over the four sides between the new frame 14 and the edge of the panel 16. The panel holding space 48 at the location facing the new vertical frame 28 is also referred to as the panel holding space 48a.

[0021] 〔Configuration of the new upper frame〕 The newly provided upper frame 24 has an outdoor metal frame 50, a first resin frame 52 and a second resin frame 34 on the indoor side. The metal frame 50 corresponds to the metal member according to the present invention. Also, the first and second resin frames 52, 34 correspond to the resin members according to the present invention. The metal frame 50 has a hollow portion 50a on the outdoor side that is long in the prospecting direction, an outdoor finding portion 50b that protrudes from the outdoor side end of the hollow portion 50a to the inner peripheral side, an indoor finding portion 50c that protrudes from the vicinity of the indoor side end of the hollow portion 50a to the inner peripheral side, and a prospecting piece 50d that extends indoors. The tip of the outdoor finding portion 50b supports the edge of the outdoor surface of the panel 16 via the pocket portion and the bead 37. The tip of the indoor finding portion 50c supports the edge of the indoor surface of the panel 16 via a part of the first resin frame 52 and the bead 37. That is, at this location, the panel holding space 48 is formed surrounded by the hollow portion 50a, the outdoor finding portion 50b, and the indoor finding portion 50c. The panel holding space 48 at this location is also referred to as the panel holding space 48b. The panel holding space 48b has an appropriate width in the prospecting direction so that the panel 16 can be assembled in the Kendon style.

[0022] The hollow portion 50a and the prospecting piece 50d have substantially the same length in the prospecting direction. The hollow portion 50a protrudes outside the existing upper frame 18. An engaging portion 50e for engaging with the first resin frame 52 is provided at the end of the prospecting piece 50d. The prospecting piece 50d is fixed to the prospecting wall of the existing upper frame 18 by screws 42 via the spacer 38 and the base member 54. The base member 54 extends to the indoor side and is fixed to the existing upper frame 18 by screws 45.

[0023] The first resin frame 52 has a hollow portion 52a that is elongated in the prospective direction as a base, and includes a prospective piece 52b that protrudes to the outdoor side, a relay piece 52c that protrudes to the indoor side, and an engagement piece 52d that protrudes from the indoor side end to the outer peripheral side. The tip of the prospective piece 52b is bent and engaged so as to mesh with the tip of the indoor-side finding portion 50c. The engagement piece 52d is engaged with the engagement portion 50e. The relay piece 52c is screwed to the second resin frame 34. The second resin frame 34 is the same as the above, but has a different length due to the folding of the folding groove 34a. Two screw insertion holes through which screws 42 pass are formed in the hollow portion 52a, but the screw insertion hole on the inner peripheral side prospective surface is blocked by a cap 56.

[0024] The hollow portion 50a is partitioned into an outdoor-side chamber 50g and an indoor-side chamber 50h by a partition wall 50f. The outdoor-side chamber 50g is slightly smaller in prospective width than the indoor-side chamber 50h. A screw hole 58 is provided at the lower part of the partition wall 50f in the hollow portion 50a. The screw hole 58 is a portion where a screw 60 (see the virtual line in FIG. 2) for joining the new vertical frame 28 and the new upper frame 24 is screwed and is for joining the vertical frames. Since the new frame 14 is a vertical winner, the new upper frame 24 is fixed by screwing the screw 60 passing through the new vertical frame 28 into the screw hole 58. The screw hole 58 has a C shape and opens downward. That is, the screw hole 58 has an opening communicating with the panel holding space 48b. All the arc walls other than the opening forming the screw hole 58 are within the range of the hollow portion 50a and do not protrude into the panel holding space 48b.

[0025] 〔Configuration of the new lower frame〕 The new lower frame 26 includes a metal frame 62 on the outdoor side, and a first resin frame 64 and a second resin frame 34 on the indoor side. The metal frame 62 corresponds to the metal member according to the present invention. Also, the first and second resin frames 64, 34 correspond to the resin members according to the present invention.

[0026] First, the first resin frame 64 will be described. The first resin frame 64 has a hollow portion 64a as a base, a projected piece 64b protruding to the outdoor side, a relay piece 64c protruding to the indoor side, and an engaging piece 64d protruding from the indoor side end to the outer peripheral side. The tip of the projected piece 64b is bent and engaged so as to mesh with the tip of the indoor-side finding portion 62f. The engaging piece 64d is engaged with the engaging portion 62j. The relay piece 64c is screwed to the second resin frame 34. The second resin frame 34 is the same as the above, but has different lengths due to the folding of the folding groove 34a. The hollow portion 64a is partitioned by a partition wall into a relatively large outdoor-side chamber 64e and a relatively small indoor-side chamber 64f. A shallow recess 64g is formed on the upper surface of the hollow portion 64a.

[0027] Next, the metal frame 62 will be described. The metal frame 62 has a relatively large first hollow portion 62a and a relatively small second hollow portion 62b adjacent to the inner peripheral side of the first hollow portion 62a. The first hollow portion 62a is large and has sufficient strength to support the self-weight of the panel 16 and the like. The indoor-side finding surfaces of the first hollow portion 62a and the second hollow portion 62b are continuous, but from the outdoor side, the second hollow portion 62b is located deeper than the first hollow portion 62a.

[0028] The metal frame 62 further has an indoor-side projected piece 62c where the inner peripheral side wall of the second hollow portion 62b extends to the indoor side, an outdoor-side projected piece 62d extending to the outdoor side, an outdoor-side finding portion 62e protruding from the outdoor-side end of the outdoor-side projected piece 62d to the inner peripheral side, an indoor-side finding portion 62f protruding from the middle of the indoor-side projected piece 62c to the inner peripheral side, a finding support piece 62g protruding from the middle of the indoor-side projected piece 62c to the outer peripheral side, a finding support piece 62h protruding from the vicinity of the boundary portion between the first hollow portion 62a and the second hollow portion 62b in the second hollow portion 62b to the indoor side, and a fixing piece 62i protruding in an L shape from the lower end of the first hollow portion 62a toward the indoor side. The finding support piece 62g is moderately long, and its tip is located on the extension of the finding support piece 62h. The finding support piece 62g is on the extension of the indoor-side finding portion 62f. The finding support piece 62h is short. An engaging portion 62j for engaging with the first resin frame 64 is provided at the end of the indoor-side projected piece 62c.

[0029] The tip of the outdoor finding portion 62e supports the edge of the outdoor surface of the panel 16 via the pocket portion and the bead 37. The tip of the indoor finding portion 62f supports the edge of the indoor surface of the panel 16 via a part of the first resin frame 64 and the bead 37. That is, at this location, the panel holding space 48 is formed surrounded by the inner peripheral side wall of the second hollow portion 62b, the indoor looking-in piece 62c, the outdoor looking-in piece 62d, the outdoor finding portion 62e, and the indoor finding portion 62f. The panel holding space 48 at this location is also referred to as the panel holding space 48c. The panel 16 is supported by the setting block 66 within the panel holding space 48c.

[0030] In the first hollow portion 62a, a screw hole 68 is provided at the lower part of the outdoor wall 62o of the second hollow portion 62b. The screw hole 68 is the part where a screw 70 (refer to the virtual line in FIG. 2) for joining the new vertical frame 28 and the new lower frame 26 is screwed, and is for joining the vertical frames. Since the new frame 14 is a vertical winner, the new lower frame 26 is fixed by screwing the screw 70 passing through the new vertical frame 28 into the screw hole 68. The screw hole 68 has the same C shape as the above screw hole 58 and opens downward. That is, the screw hole 68 has an opening communicating with the first hollow portion 62a. All the arc walls forming the screw hole 68 are within the range of the first hollow portion 62a and do not protrude into the second hollow portion 62b and the outdoor communication space 62k communicating with the outside. Note that the screw hole 68 and the above screw hole 58 are in overlapping positions in plan view, and the screw 70 and the above screw 60 are in overlapping positions in plan view.

[0031] Returning to FIG. 1, the connection and fixation between the existing lower frame 20 and the new lower frame 26 will be described. In the cross section of FIG. 1, the metal frame 62 is connected and fixed to the new lower frame 26 at two locations (however, a plurality of locations are fixed along the longitudinal direction of the frame material). One location is the L-shaped tip of the fixing piece 62i, which is fixed to the lower end looking-in wall of the new lower frame 26 by a screw 79.

[0032] Another location is at the indoor-side projected piece 62c, which is part of the projected wall in the panel holding space 48c, and is indirectly connected and fixed via the base member 80 by screws 42. The base member 80 has an L-shaped configuration consisting of a first side portion 80a forming a long side in the finding direction and a second side portion 80b forming a short side in the projected direction. The screws 42 fix the metal frame 62 by screwing through the indoor-side projected piece 62c into the second side portion 80b. A plurality of screws 42 are provided at positions avoiding the setting block 66.

[0033] The first side portion 80a abuts against the outdoor-side finding wall 20b of the existing lower frame 20, and this portion is fixed by screws 82. In this embodiment, there is a pocket 20c on the indoor side of the outdoor-side finding wall 20b, and the screws 82 are screwed from the outdoor-side finding wall 20b into the pocket 20c.

[0034] The inner peripheral-side ends of the first side portion 80a and the outdoor-side finding wall 20b coincide. The first side portion 80a is slightly longer than the outdoor-side finding wall 20b on the outer peripheral side. The second side portion 80b protrudes outward from the inner peripheral-side end of the first side portion 80a, and its tip abuts against the indoor-side finding wall 62p. The tip of the finding support piece 62g abuts against the indoor-side end of the second side portion 80b, and the projected support piece 62h abuts against the upper surface of the outdoor-side end, stably supporting the metal frame 62 in the projected direction and the finding direction.

[0035] The heads of the screws 42 are exposed within the panel holding space 48c, but since the panel holding space 48c is not visible from the indoor and outdoor sides, the heads are not visually recognized either. The connection and fixation between the existing lower frame 20 and the new lower frame 26 may be achieved by providing screw through-holes in the resin frame portion like the connection and fixation between the existing upper frame 18 and the new upper frame 24, fixing with screws 42 at the back, and then closing the screw through-holes with caps 56. However, the first resin frame 64 of the new lower frame 26 is in a relatively visible position, and moreover, a plurality of screws 42 need to be provided along the long direction of the frame material, making them conspicuous. Therefore, it is desirable to make them invisible by utilizing the panel holding space 48c. Thereby, a suitable design can be maintained.

[0036] Further, although the panel holding space 48c is a location that receives a relatively large load due to the wind pressure on the panel 16, in this embodiment, it has a sufficiently short connection path via the screws 42 and the base member 80 to the existing lower frame 20, enabling reliable load support at the existing lower frame 20 and improving the wind resistance. Also, although the panel holding space 48c receives the self-weight of the panel 16, the existing lower frame 20 can reliably support this self-weight due to the short connection path.

[0037] The base member 80 is preferably applied in a form where the second side portion 80b protrudes from the first side portion 80a in the outdoor direction, and the panel holding space 48c and the hollow portions 62a, 62b are arranged on the outdoor side of the existing lower frame 20. However, depending on the conditions, the second side portion 80b may protrude inward. Also, depending on the conditions, the base member 80 may be omitted, and the panel holding space 48c may be directly connected and fixed to the existing lower frame 20 with the screws 42.

[0038] 〔Configuration of the gap member〕 Between the existing frame 12 and the new frame 14 described above, a closing member 100 is provided to close the gap between the existing frame 12 and the new frame 14 and ensure the heat shielding property in the gap. This closing member 100 includes an upper closing member 200 that closes the gap between the existing upper frame 18 and the new upper frame 24, and vertical closing members 300 that each close the gap between the left and right existing vertical frames 22 and the left and right new vertical frames 28. In this embodiment, since there is no gap between the existing lower frame 20 and the new lower frame 26, no closing member is provided therebetween. And the upper closing member 200 and the left and right vertical closing members 300 are connected to each other by a vertical overlapping structure. Each member constituting these closing members 100 is an extruded molding made of a metal such as an aluminum alloy and is configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction.

[0039] The upper closing member 200 is composed of two members, a first closing member 210 and a second closing member 220.

[0040] The first closing member 210 is a portion fixed to the existing upper frame 18. This first closing member 210 has a substantially L-shaped cross section including a fixing portion 211 and an existing frame side connecting portion 212. The fixing portion 211 has a substantially flat plate shape extending substantially parallel to the indoor-side finding surface 18a of the existing upper frame 18, and is a portion fixed to the finding surface 18a by screws 231. The existing frame side connecting portion 212 has a substantially flat plate shape extending in the prospective direction from the inner peripheral side end of the fixing portion 211 toward the indoor side, and is a portion connected to the second closing member 220 by screws 232.

[0041] The second closing member 220 is a portion fixed to the new upper frame 24. This second closing member 220 has a substantially flat plate shape extending substantially parallel to the prospective piece 50d of the new upper frame 24, and is fixed to the prospective surface on the outer peripheral side of the prospective piece 50d by screws 233. Further, when the second closing member 220 is fixed to the new upper frame 24, it protrudes from the indoor-side tip of the prospective piece 50d toward the indoor side. And the second closing member 220 is connected to the existing frame side connecting portion 212 by screws 232 in a state where the protruding portion overlaps below the existing frame side connecting portion 212.

[0042] The vertical closing member 300 is composed of two members, a first closing member 310 and a second closing member 320.

[0043] The first closing member 310 is a portion fixed to the existing vertical frame 22. This first closing member 310 has a substantially L-shaped cross section including a fixing portion 311 and an existing frame side connecting portion 312. The fixing portion 311 has a substantially flat plate shape extending substantially parallel to the indoor-side finding surface 22a of the existing vertical frame 22, and is a portion fixed to the finding surface 22a by screws 331. The existing frame side connecting portion 312 has a substantially flat plate shape extending in the prospective direction from the inner peripheral side end of the fixing portion 311 toward the indoor side, and is a portion connected to the second closing member 320 by screws 332.

[0044] The second closing member 320 is a portion fixed to the newly installed vertical frame 28. This second closing member 320 has a substantially flat plate shape extending substantially parallel to the projected piece 30c in the newly installed vertical frame 28, and is fixed to the projected surface on the outer peripheral side of the projected piece 30c by screws 333. Further, when the second closing member 320 is fixed to the newly installed vertical frame 28, it protrudes inward from the tip of the projected piece 30c on the indoor side. Then, the second closing member 320 is connected to the existing frame side connecting portion 312 by screws 332 in a state where the protruding portion overlaps the inner peripheral side of the existing frame side connecting portion 312.

[0045] 〔Construction method of fittings〕 Next, the construction method of the above-described fitting 10 will be described. Figs. 3A to 3E and Figs. 4A to 4E are diagrams for explaining the construction method of the fitting 10. Specifically, Figs. 3A to 3E are longitudinal sectional views corresponding to Fig. 1. Figs. 4A to 4E are cross-sectional views corresponding to Fig. 2. First, the operator cuts the fin portions 18b and 22b protruding inward on the inner peripheral sides provided on the existing upper frame 18 and the left and right existing vertical frames 22 (Figs. 3A and 4A). Further, the operator fixes the base members 54, 80, and 40 to the existing upper frame 18, the existing lower frame 20, and the left and right existing vertical frames 22 by screws 53, 82, and 45, respectively (Figs. 3A and 4A).

[0046] Next, the operator moves the newly installed frame 14 from the outdoor side of the existing frame 12 and installs the newly installed frame 14 on the inner peripheral side of the existing frame 12 (Figs. 3B and 4B: newly installed frame installation step). At this time, as the newly installed upper frame 24, the newly installed lower frame 26, and the left and right newly installed vertical frames 28 constituting the newly installed frame 14 installed on the inner peripheral side of the existing frame 12 in this newly installed frame installation step, only the first resin frames 52, 64, and 32 are fixed to the metal frames 50, 62, and 30, and the second resin frames 54 and 34 are not connected.
