Mode for Carrying Out the Invention
[0009] 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.
[0010] 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. A surface and a wall along the prospective direction may be referred to as a prospective surface and a prospective wall, respectively. 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 an object extending horizontally such as an upper frame, a lower frame, an upper sash, a 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 an object extending vertically such as a vertical frame, a vertical sash, etc. A surface and a wall along the finding direction may be referred to as a finding surface and a finding wall, respectively.
[0011] FIG. 1 is a longitudinal sectional view of a fitting 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the fitting 10. However, since the fitting 10 is basically symmetric about the left-right axis, only the left side portion is shown in FIG. 2.
[0012] The fitting 10 is a retrofit fitting in which a new frame 14 is provided on the inner peripheral side of an existing frame 12, and 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. By not removing the existing frame 12, the fitting 10 can reduce the construction cost. 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. 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 material and a resin material.
[0013] The existing frame 12 is configured by surrounding the upper frame 18, the lower frame 20, and the left and right vertical frames 22. The new frame 14 is configured by surrounding the upper frame 24, the lower frame 26, and the left and right vertical frames 28. The new frame 14 has a vertical-lapping structure.
[0014] The vertical frame 28 has an outdoor-side metal frame 30, an indoor-side first resin frame 32, and a second resin frame 34. A pressing edge 36 is attached to the vertical frame 28. The metal frame 30 has an outdoor-side hollow portion 30a that is long in the prospective direction, an outdoor-side finding portion 30b that protrudes toward the inner peripheral side, and a prospective piece 30c that extends toward the indoor side. The tip of the outdoor-side finding portion 30b supports the edge of the outdoor surface of the panel 16 via a pocket portion and a bead 37.
[0015] The length of the hollow portion 30a and the protruding piece 30c in the protruding direction is substantially the same. Almost all of the hollow portion 30a protrudes outside the room from the existing vertical frame 22. On the inner peripheral side closer to the room of the hollow portion 30a, a first engaging portion 30d and a second engaging portion 30e for engaging with the pressing edge 36 are provided. The first engaging portion 30d and the second engaging portion 30e are in an L shape protruding toward the adjacent side. The first engaging portion 30d is on the outside and outer peripheral side of the second engaging portion 30e. On the indoor-side facing 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 protruding piece 30c, a fourth engaging portion 30g for engaging with the first resin frame 32 is provided. The protruding piece 30c is fixed to the protruding wall of the 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 vertical frame 22 by screws. The base member 40 and the base members 54 and 80 described later are made of an aluminum alloy material or a stainless steel material, etc., and are of high strength.
[0016] The first resin frame 32 has a hollow portion 32a elongated in the protruding direction as a base, and has a protruding piece 32b protruding outside the room, a relay piece 32c protruding inside the room, and an engaging piece 32d protruding on the outer peripheral side. An engaging piece 32e protrudes outside the hollow portion 32a. The tip of the protruding 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 protruding piece 32b, but it is covered by the pressing edge 36 and is not visually recognized. The tip of the engaging piece 32d engages with the fourth engaging portion 30g.
[0017] 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 break-off grooves 34a are provided in this L portion, and by breaking off any one of the break-off grooves 34a, the distance from the existing frame 12 or the housing can be adjusted. A gap filling member 43 is provided adjacent to the tip of the second resin frame 34. The second resin frame 34 functions as a frame.
[0018] The edge trim 36 has a metal edge trim 44 on the outdoor side and a resin edge trim 46 on the indoor side. The metal edge trim 44 and the resin edge trim 46 are strongly engaged with each other at the L-shaped and square U-shaped engagement portions. The metal edge trim 44 has a fixing piece 44a that extends obliquely toward the outdoor side. The tip of the fixing piece 44a is engaged with the first engagement portion 30d, and the recess formed at the end is engaged with the second engagement portion 30e. The resin edge trim 46 has a substantially square cross section and is partitioned into two rooms arranged in the finding direction. An engagement piece 46a projects from the indoor side of the resin edge trim 46 to the outer peripheral side and is engaged with the engagement piece 32e.
[0019] A part of each of the metal edge trim 44 and the resin edge trim 46 of the edge trim 36 forms a finding portion 36a. The inner peripheral side end of the finding portion 36a supports the edge of the indoor surface of the panel 16 via a bead 37. A panel holding space 48 surrounded by the prospective 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. The panel holding space 48 is formed to communicate over four sides between the new frame 14 and the edge of the panel 16. The panel holding space 48 formed in the vertical frame 28 is also referred to as the vertical frame panel holding space 48a.
[0020] (Regarding the upper frame 24, the screw hole 58, and its peripheral portion) The upper frame 24 has a metal frame 50 on the outdoor side, a first resin frame 52 and a second resin frame 34 on the indoor side. The metal frame 50 has a hollow portion 50a on the outdoor side that is long in the prospective 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 prospective piece 50d that extends on the indoor side. The tip of the outdoor finding portion 50b supports the edge of the outdoor surface of the panel 16 via a pocket portion and a 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 a 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 formed in the upper frame 24 is also called the upper frame panel holding space 48b. The upper frame panel holding space 48b has an appropriate width in the prospective direction so that the panel 16 can be assembled in a Kenden style.
[0021] The hollow portion 50a and the prospective piece 50d have substantially the same length in the prospective direction. The hollow portion 50a protrudes outside the outdoor side of the existing vertical frame 22. An engaging portion 50e for engaging with the first resin frame 52 is provided at the end of the prospective piece 50d. The prospective piece 50d is fixed to the prospective wall of the upper frame 18 by screws 42 via a spacer 38 and a base member 54. The base member 54 extends to the indoor side and is fixed to the upper frame 18 by screws.
[0022] The first resin frame 52 has a long and narrow hollow portion 52a in the prospective direction as a base, a prospective piece 52b that protrudes outside the outdoor side, a relay piece 52c that protrudes inside the indoor side, and an engaging piece 52d that protrudes from the indoor side end to the outdoor side. The tip of the prospective piece 52b is bent and engaged so as to mesh with the tip of the indoor finding portion 50c. The engaging piece 52d is engaged with the engaging 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 the 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.
[0023] The hollow portion 50a is partitioned by a partition wall 50f into an outdoor-side chamber 50g and an indoor-side chamber 50h. The outdoor-side chamber 50g is slightly narrower in the prospective width than the indoor-side chamber 50h. In the hollow portion 50a, screw holes 58 are provided at the lower part of the partition wall 50f. The screw holes 58 are the portions where screws 60 (refer to the phantom line in Fig. 2) for joining the vertical frame 28 and the upper frame 24 are screwed, and are for joining the vertical frames. Since the new frame 14 is a vertical winner, the upper frame 24 is fixed by screwing the screws 60 passing through the vertical frame 28 into the screw holes 58. The screw holes 58 are C-shaped and open downward. That is, the screw holes 58 have openings communicating with the upper frame panel holding space 48b. All the arc walls other than the openings forming the screw holes 58 are within the range of the hollow portion 50a and do not protrude into the upper frame panel holding space 48b.
[0024] The screw holes 58 are located outside the outdoor-side finding surface of the existing upper frame 18, and water may enter through the screws 60 and the screw holes 58. However, since the screw holes 58 provided in contact with the hollow portion 50a open into the inner peripheral side vertical frame panel holding space 48a, there is no water intrusion into the interior of the hollow portion 50a, and means such as a drain valve are not required for the hollow portion 50a. Thus, in the fitting 10, water intrusion into the hollow portion 50a can be prevented with a simple and inexpensive configuration. The water that enters the upper frame panel holding space 48b is drained to the outside through the vertical frame panel holding space 48a, the lower frame panel holding space 48c (described later), and the drain holes 62m. Since the screw holes 58 are provided on the inner peripheral side prospective wall of the metal frame 50, the distance to the panel 16 is relatively short, which is suitable for the framework. In this embodiment, such a configuration is applied to the upper frame 24, but it may also be applied to the lower frame 26 to open the screw holes into the lower frame panel holding space 48c.
[0025] (Regarding the lower frame 26, the screw holes 68, and their peripheral parts) The lower frame 26 has an outdoor-side metal frame 62, an indoor-side first resin frame 64, and a second resin frame 34.
[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. A drain hole 64h is formed at the lower portion 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 includes 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 part 62e supports the edge of the outdoor surface of the panel 16 via the pocket part and the bead 37. The tip of the indoor finding part 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 second hollow part 62b, the indoor looking-in piece 62c, the outdoor looking-in piece 62d, the outdoor finding part 62e, and the indoor finding part 62f. The panel holding space 48 formed in the lower frame 26 is also called the lower frame panel holding space 48c. The panel 16 is supported by the setting block 66 within the lower frame panel holding space 48c.
[0030] An outdoor communication space 62k that opens to the outside is formed by the inner peripheral wall of the first hollow part 62a, the outdoor wall of the second hollow part 62b, and the outdoor looking-in piece 62d. The outdoor looking-in piece 62d is provided with a drain hole 62m that communicates with the outdoor communication space 62k. At the tip of the outdoor looking-in piece 62d, there is a small downward protruding piece 62n so that the drain hole 62m is not conspicuous.
[0031] In the first hollow part 62a, a screw hole 68 is provided at the lower part of the outdoor wall 62o of the second hollow part 62b. The screw hole 68 is the part where a screw 70 (refer to the virtual line in Fig. 2) that joins the vertical frame 28 and the lower frame 26 is screwed, and it is for joining the vertical frames. Since the new frame 14 is vertical, the lower frame 26 is fixed by screwing the screw 70 that penetrates the 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 that communicates with the first hollow part 62a. All the arc walls forming the screw hole 68 are within the range of the first hollow part 62a and do not protrude into the second hollow part 62b and the outdoor communication space 62k. 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.
[0032] At the lower end of the indoor-side finding wall 62p of the first hollow portion 62a, a first drain hole 62q is formed. A second drain hole 62r is formed at a location closer to the outdoor side in the extending portion of the fixing piece 62i in the prospective direction. The first drain hole 62q and the second drain hole 62r are adjacent to each other. The newly installed lower frame 26 and the existing lower frame 20 are separated in the prospective direction to form a drainage intermediate space 72. The first drain hole 62q opens into the drainage intermediate space 72.
[0033] In the existing lower frame 20, a drain hole 20a is formed in a part of the prospective wall. Therefore, the water that has entered the recess 64g due to condensation or the like is drained into the drainage intermediate space 72 through the two drain valves 74 and the drain holes 64h, 20a.
[0034] The screw hole 68 is located outside the outdoor-side finding surface of the existing lower frame 20, and water may enter through the screw 70 and the screw hole 68. Since the water that has entered the first hollow portion 62a from the screw hole 68 is drained from the first drain hole 62q of the indoor-side finding wall 62p, there are no exposed holes or drain valves on the outdoor surface, and the water in the first hollow portion 62a can be discharged while maintaining a suitable design. Basically, a drain valve, a filter, etc. are not required for the first drain hole 62q and the second drain hole 62r, and the structure is simple. The second drain hole 62r is in a deep position and has a downward opening, so it is hardly visible from the outdoor side.
[0035] The drainage intermediate space 72 is originally a space for discharging condensed water or the like that can enter the existing lower frame 20 from the drain hole 20a, and it is reasonable to also use it as a drainage path for the water in the first hollow portion 62a. Note that since a seal member 76 provided with a drain pipe 76a may be provided at the lower part of the first hollow portion 62a as shown by the virtual line in FIG. 1, it is not preferable to provide the first drain hole 62q on the lower surface of the first hollow portion 62a because there is a concern that it will be blocked by the seal member 76. The first drain hole 62q, the second drain hole 62r, the drain holes 20a, 62m, 64h, etc. may be provided, for example, near both ends in the longitudinal direction of the frame material.
[0036] (Regarding the connection and fixation of the lower frame 20 and the lower frame 26) Returning to FIG. 1, the connection and fixation between the lower frame 20 and the lower frame 26 will be described. In the cross-section of FIG. 1, the metal frame 62 is connected and fixed to the lower frame 26 at two locations on the lower frame 20 (however, a plurality of locations are fixed along the longitudinal direction of the frame member). One location is the L-shaped tip of the fixing piece 62i, which is fixed to the prospective wall at the lower end of the lower frame 26 by screws 79.
[0037] The other location is at the indoor prospective piece 62c, which is a part of the prospective wall in the lower frame panel holding space 48c, and is indirectly connected and fixed by screws 42 through the base member 80. 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 prospective direction. The screws 42 fix the metal frame 62 by screwing through the indoor prospective piece 62c into the second side portion 80b. A plurality of screws 42 are provided at positions avoiding the setting block 66.
[0038] The first side portion 80a is in contact with the outdoor finding wall 20b of the 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 finding wall 20b, and the screws 82 are screwed from the outdoor finding wall 20b to the pocket 20c.
[0039] The present invention is not limited to the above-described embodiments, and it goes without saying that it can be freely changed without departing from the gist of the present invention.
[0040] The fitting according to the present embodiment is a fitting for holding a panel on the inner peripheral side of a frame body, wherein an edge of the panel is held by an outdoor finding portion and an indoor finding portion, a panel holding space surrounded by a prospective surface, an outdoor finding portion, and an indoor finding portion of the frame body is formed, and at least one of an upper frame and a lower frame of the frame body has a hollow portion, and a screw hole for vertical frame joining has an opening communicating with the panel holding space on the inner peripheral side.
[0041] Thereby, water does not enter the hollow portion from the screw hole, and it is not necessary to provide drainage means in the hollow portion.
[0042] When the screw holes for vertical frame joining are provided in the prospective wall on the inner peripheral side of the upper frame, water is discharged downward directly from the screw holes.
[0043] The panel holding space is composed of an upper frame panel holding space formed in the upper frame, a lower frame panel holding space formed in the lower frame, and vertical frame panel holding spaces formed in the left and right vertical frames, and is formed along the four circumferences of the panel. Water that has entered the upper frame panel holding space may be drained to the outside from the lower frame panel holding space through the vertical frame panel holding space. Thereby, water can be discharged from the panel holding space.
[0044] The frame body is a newly installed frame provided on the inner peripheral side of an existing frame, and the screw holes may be on the outdoor side of the outdoor side finding surface of the existing frame.
