[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-163876 Summary of the Invention [Problem to be solved by the invention]

[0004] In the fittings of Patent Document 1, the cover material is attached to the frame material with the fins protruding from the cover material in close contact with the visible surface of the frame material. For this reason, this configuration raises concerns that drainage in the space between the cover material and the frame material will be impeded, causing the wooden frame material to rot. Even if the frame material is not made of wood, for example a resin frame material, the accumulation of rainwater and the like in the space will pose a hygiene problem.

[0005] The present invention has been made in consideration of the problems with the conventional technology described above, and has an object to provide a fixture that can improve drainage performance. [Means for solving the problem]

[0006] A fixture according to one embodiment of the present invention is a fixture in which a panel material is supported by a frame body having a frame material and a cover material attached to the frame material, and is equipped with a setting block having a placement surface to be placed on the inner frame surface of the frame material and a support surface that supports the lower end surface of the panel material, and the cover material has a fin portion that protrudes toward the frame material, and the fin portion is supported by the setting block between the placement surface and the support surface.

[0009] BEST MODE FOR CARRYING OUT THE DISCLOSURE Hereinafter, preferred embodiments of the fitting according to the present invention will be described in detail with reference to the accompanying drawings.

[0010] As shown in FIG. 1 and FIG. 2, the fitting 10 according to this embodiment includes an opening frame 12 fixed to an opening of a building frame 11, and an inner screen 14 and an outer screen 15 supported on the inside of the opening frame 12. In this embodiment, a single-sliding window fitting 10 is exemplified, in which the inner screen 14 is supported slidably relative to the opening frame 12, and the outer screen 15 is fixedly fitted to the opening frame 12. The fitting 10 may be a double-sliding window in which both the screens 14 and 15 are slidable relative to the opening frame 12. The number of screens may be one or three or more. The present invention can be effectively used in addition to such sliding window fittings, and can be applied to various fittings, such as opening and closing windows such as sliding windows and vertical sliding windows, and sash windows.

[0011] The opening frame 12 is formed by framing an upper frame 12a, a lower frame 12b, and left and right vertical frames 12c, 12d all around, forming a rectangular opening.

[0012] In this application, the prospective direction refers to the indoor / outdoor direction of the fitting 10, that is, the direction from the indoor side to the outdoor side or the opposite direction (the direction indicated by the arrow Z in the figure), and the prospective surface refers to a surface extending along the prospective direction. The prospective direction is a direction perpendicular to the prospective direction, and in the case of a vertical frame 12c that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction indicated by the arrow X in the figure), and in the case of an upper frame 12a that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction indicated by the arrow Y in the figure). The prospective surface refers to a surface along the prospective direction. The frame inner side refers to the inner part of the opening frame 12, which is a frame-shaped member. The frame outer side refers to the outer part of the opening frame 12, which is a frame-shaped member. The frame inner direction refers to the direction from the frame outer side of the frame-shaped member toward the frame inner side. The frame outer direction refers to the direction from the frame inner side of the frame-shaped member toward the frame outer side.

[0013] First, the overall configuration of the fitting 10 will be described.

[0014] The opening frame 12 has frame members 18a-18d disposed on the indoor side and cover members 20a-20d covering the outdoor side of the frame members 18a-18d. The cover members 20a-20d may cover the entire outdoor facing surfaces of the frame members 18a-18d or may cover at least a part of them.

[0015] The upper frame 12a is composed of a frame material 18a and a cover material 20a, and the lower frame 12b is composed of a frame material 18b and a cover material 20b. The vertical frames 12c and 12d are composed of frame materials 18c and 18d and cover materials 20c and 20d, respectively. The frame materials 18a to 18d are made of wood. The frame materials 18a to 18d may be made of resin such as polyvinyl chloride resin (PVC) or metal such as aluminum. The frame materials 18a to 18d are fixed to the main body 11 with screws 22. Reference numeral 23 in Figs. 1 and 2 denotes a wooden frame member. The cover materials 20a to 20d are made of metal such as aluminum. The cover materials 20a, 20c, and 20d are fixed to the frame materials 18a, 18c, and 18d, respectively, using screws 24. The cover material 20b is fastened together with the frame material 18b with the screws 22.

[0016] The inner screen 14 comprises a panel 26 and a frame 28 that surrounds and supports the panel 26 on all four sides. The panel 26 is, for example, a triple-layered glass made up of three glass sheets arranged with a spacer in between. The panel 26 may be a single-layered, two-layered, or four or more-layered structure.

[0017] The frame body 28 is a rectangular opening formed by framing the upper frame 28a, the lower frame 28b, and a pair of vertical frames 28c, 28d on the left and right sides. The frame body 28 has frame members 30a to 30d arranged on the indoor side and cover members 32a to 32d that cover the outdoor side of the frame members 30a to 30d. The frame members 30a to 30d are made of wood. The frame members 30a to 30d may be made of resin such as polyvinyl chloride resin or metal such as aluminum. The upper frame 28a is made of the frame member 30a and the cover member 32a, and the lower frame 28b is made of the frame member 30b and the cover member 32b. The vertical frames 28c, 28d are made of the frame members 30c, 30d and the cover members 32c, 32d, respectively. The frame members 30a-30d have wooden battens 36 attached to the indoor-side end of each frame-inside visible surface 34. The battens 36 are members that press and support the indoor-side surface of the panel 26. The cover materials 32a-32d may cover the entire outdoor-side visible surfaces of the frame members 30a-30, or may cover at least a portion of them.

[0018] A guide piece 38 is attached to the frame outer projection surface of the frame material 30a of the upper frame 28a. The guide piece 38 is slidably inserted into a guide groove 39 formed on the frame inner projection surface of the upper frame 12a. A door roller 40 protrudes from the frame outer projection surface of the frame material 30b of the lower frame 28b. The door roller 40 can roll on a guide rail 41 that protrudes from the frame inner projection surface of the lower frame 12b.

[0019] One of the vertical frames, 28c, serves as the door end frame. A receiving part 42 is attached to the frame material 30c of the vertical frame 28c on the outer frame front surface. A lock pin 43 protruding from the inner frame front surface of the vertical frame 12c engages and disengages with the receiving part 42. The other vertical frame, 28d, serves as the door joint frame. The frame material 30d of the vertical frame 28d is positioned so that it meets the vertical frame 52 of the outer shoji screen 15. A smoke deflector is provided between the vertical frames 28d, 52.

[0020] In Fig. 1, the guide piece 38 is misaligned from the guide groove 39 toward the outside of the room, and the roller 40 is tilted at an angle. This is because the lock pin 43 engages with the receiving part 42, locking the inner screen 14 in the fully closed position relative to the opening frame 12, and the state in which the inner screen 14 has moved beyond its normal sliding position is shown. Reference numeral 44 in Fig. 2 is an operating handle for opening and closing the inner screen 14, and is attached to the interior facing surface of the vertical frame 28c.

[0021] The cover materials 32a-32d are made of a metal such as aluminum. The cover materials 32a-32d are attached to the frame materials 30a-30d so as to cover the outdoor facing surfaces 46 of the frame materials 30a-30d, respectively. A ridge 48 is formed on the inner frame end of each of the cover materials 32a-32d. The ridge 48 is a portion that supports the outdoor surface of the face material 26. The indoor and outdoor surfaces of the four peripheral edges of the face material 26 are supported by the ridges 36, 48, and thus the face material 26 is supported by the frame 28.

[0022] The outer screen 15 includes a surface material 50. The surface material 50 is, for example, a triple-layer glass having three glass sheets arranged with a spacer between them. The surface material 50 may have a one-layer, two-layer, or four or more layer structure.

[0023] The upper edge of the surface material 50 is supported by the cover material 20a of the upper frame 12a and a wooden batten 54 (see FIG. 1) fixed to the inner frame surface of the frame material 18a. The lower edge of the surface material 50 is supported in an opening groove formed in the inner frame surface of the lower frame 12b. One vertical edge of the surface material 50 is supported by a vertical frame 52 standing between the frames 12a and 12b. The vertical frame 52 has a frame material 52a arranged on the indoor side and a cover material 52b covering the outdoor side of the frame material 52a. The frame material 52a is made of wood. The frame material 52a may be made of a resin such as polyvinyl chloride resin or a metal such as aluminum. The cover material 52b is made of a metal such as aluminum. The frame material 52a of the vertical frame 52 is arranged so as to meet the vertical frame 28d of the inner sash 14. The other vertical edge of the panel 50 is supported by the cover material 20d of the vertical frame 12d and a wooden batten 55 fixed to the inner frame surface of the frame material 18d. The batten 55 is also attached to the indoor end of the inner frame surface of the frame material 52a. The battens 54, 55 are members that support the indoor surface of the panel 50.

[0024] The support structure of the outer screen 15 with respect to the opening frame 12 may be other than that described above. When the outer screen 15 is a sliding screen, the outer screen 15 may have a structure similar to that of the inner screen 14, for example.

[0025] Next, a specific example of the configuration of the lower frame 28b of the inner screen 14 and its surrounding area will be described.

[0026] As shown in Figures 3 to 5, the lower frame 28b is configured by covering the outdoor facing surface 46 of the indoor frame material 30b with a cover material 32b. In Figure 3, the illustration of the battens 36 attached to the frame materials 30b to 30d is omitted.

[0027] The frame material 30b is a wooden frame material having a substantially rectangular cross-sectional shape. An inclined surface 34a is provided on the upper surface of the frame material 30b, which is the inner frame projection surface 34, which gradually slopes downward toward the outside of the room. The inclined surface 34a is provided on most of the inner frame projection surface 34 except for the inner end portion on the indoor side. The inclined surface 34a may be provided over the entire projection width of the inner frame projection surface 34. A thin groove 34b is formed on the inner end portion of the inner frame projection surface 34, which is a horizontal surface. A water-stopping material 58 is attached to the groove 34b. The water-stopping material 58 waterproofs the joint surface between the edge 36 and the inner frame projection surface 34.

[0028] The cover material 32b is a metal extrusion member that is thin in the projection direction (Z direction). The cover material 32b has a ridge 48, a fin portion 60, a pocket portion 62, and a claw portion 64.

[0029] The fin portion 60 protrudes from the inner surface 65 of the cover material 32b toward the frame material 30b. The inner surface 65 is a surface facing the frame material 30b (the room side). The fin portion 60 is provided between the pressing edge 48 and the pocket portion 62 in the vertical direction, and extends over substantially the entire length of the cover material 32b. The tip of the fin portion 60 is disposed between the lower end surface 26a of the face material 26 and the frame inner side projection surface 34 (inclined surface 34a) of the frame material 30b. At the tip of the fin portion 60, a convex portion 60a protruding toward one surface (lower surface) is bent and formed. In FIG. 4, the convex portion 60a protrudes toward the lower surface of the fin portion 60, but it may protrude toward the upper surface.

[0030] The pocket portion 62 has a pair of upper and lower protrusions 62a, 62b protruding from the inner surface 65 of the cover material 32b toward the frame material 30b, and is formed by grooves provided in the protrusions 62a, 62a that face each other. The pocket portion 62 is provided below the fin portion 60 in the vertical direction of the inner surface 65, and extends over approximately the entire length of the cover material 32b. The upper protrusion 62a is located in a position facing an R-shaped portion formed at the corner between the inclined surface 34a of the frame material 30b and the exterior facing surface 46. The lower protrusion 62b is located in a position facing the exterior facing surface 46 of the frame material 30b. The protrusions 62b may have a cutout portion 66 in which a part of the longitudinal direction is cut off (see FIG. 5). The cutout portion 66 becomes a part of the drainage path described later.

[0031] The pocket portion 62 can be used as an attachment portion of the connecting fitting 68 (see FIG. 5). The connecting fitting 68 is a fitting that connects the cover material 32b of the lower frame 28b, which is a horizontal frame, to the cover materials 32c, 32d of the vertical frames 28c, 28d. The connecting fitting 68 is a metal plate made of stainless steel, steel, or the like. The connecting fitting 68 is arranged along the XY direction and is a plate that is thin in the Z direction. This allows the connecting fitting 68 to be installed in the narrow space in the Z direction between the cover material 32b and the exterior facing surface 46. Fin portions 69 are formed to protrude from the inner surface of the cover materials 32c, 32d. The fin portions 69 are portions that abut against the end surface of the cover material 32b. The connecting fitting 68 has a tip portion 68a that is narrow in the Y direction inserted into the pocket portion 62. A crimp fixing portion 70 formed by crushing the protrusions 62a, 62b is fitted into the tip portion 68a, thereby fixing the connecting fitting 68 to the cover material 32b. A base portion 68b that is wider in the Y direction than the tip portion 68a is provided at the base end of the connecting fitting 68. The tip portion 68a of the connecting fitting 68 is inserted into a hole portion 69a formed in a fin portion 69, and the base portion 68b is engaged with the fin portion 69. This allows the connecting fitting 68 to connect the cover material 32b to the cover materials 32c, 32d.

[0032] 5 shows only the cover material 32c of one vertical frame 28c, the relationship between the cover material 32d of the other vertical frame 28d and the connecting fitting 68 may be the same or similar except that it is symmetrical (see FIG. 2). The cover material 32a of the upper frame 28a and the cover materials 32c, 32d of the vertical frames 28c, 28d can also be connected using the connecting fitting 68 in the same manner as in the case of the lower frame 28b (see FIG. 1).

[0033] The claw portion 64 is formed on the indoor side of a hollow portion formed at the lower end of the cover material 32b. The claw portion 64 is formed, for example, of an upper protruding piece and a lower L-shaped protruding piece. One end of an L-shaped bracket 72 is engaged with the claw portion 64. The bracket 72 is a member made by bending a metal plate such as stainless steel or steel. The other end of the bracket 72 is screwed to the lower surface (outer frame surface) of the frame material 30b. In other words, by engaging one end of the bracket 72, the other end of which is fixed to the frame material 30b, with the claw portion 64, the lower parts of the frame material 30b and the cover material 32b are positioned relative to each other in the YZ direction.

[0034] As shown in Figure 4, the bottom frame 28b supports the bottom end surface 26a of the face material 26 with a setting block 74 placed on the frame inner projection surface 34 of the frame material 30b. Incidentally, setting blocks used in general window fittings have a simple rectangular parallelepiped shape and their only function is to support the face material. In contrast, the setting block 74 of this embodiment has a function of supporting the face material 26 as well as the cover material 32b.

[0035] Next, the configuration and function of the setting block 74 will be described.

[0036] As shown in Figs. 3 to 7, the setting block 74 has a mounting surface 75, a support surface 76, a pair of mounting holes 77, 77, and a holding portion 78. The setting block 74 is molded from rubber or resin. The setting block 74 is a piece component having a width dimension significantly shorter than the overall length of the lower frame 28b in the longitudinal direction. The setting blocks 74 are provided in pairs, for example, on the left and right sides in the longitudinal direction of the lower frame 28b (see Fig. 3), but the number and positions of the setting blocks can be changed as appropriate.

[0037] The placement surface 75 is a surface on which the setting block 74 is placed on the frame inner projection surface 34 of the frame material 30b. In the frame material 30b of this embodiment, most of the frame inner projection surface 34 is formed by the inclined surface 34a. Therefore, the placement surface 75 is composed of an inclined surface along the inclined surface 34a, that is, an inclined surface that gradually slopes downward from the indoor side to the outdoor side. As shown in FIG. 4, the lower end surface 26a of the surface material 26 protrudes slightly into the indoor side from the inclined surface 34a. In other words, the projection dimension of the lower end surface 26a is larger than the projection dimension of the inclined surface 34a. Therefore, at the indoor end of the placement surface 75, a horizontal surface 75a is formed to be placed on the horizontal surface formed at the indoor end of the frame inner projection surface 34. The setting block 74 has a vertical slit-shaped cut 75b at the boundary between the inclined surface of the placement surface 75 and the horizontal surface 75a. The slit 75b serves as a bending portion that enables the mounting surface 75 to smoothly adapt to changes in slope of the frame inner projection surface 34.

[0038] The support surface 76 is a surface that supports the lower end surface 26a of the face material 26. The support surface 76 is formed as a horizontal surface parallel to the lower end surface 26a. Therefore, the support surface 76 and the placement surface 75 are not parallel to each other.

[0039] Each mounting hole 77 is an insertion hole for a screw 79. The screw 79 is for fixing the setting block 74 to the frame material 30b. That is, the setting block 74 is pressed by the weight of the face material 26, and the mounting surface 75 is pressed against the frame inner projection surface 34, so that the setting block 74 does not easily shift out of position. However, in the present embodiment, most of the mounting surface 75 of the setting block 74 is placed on the inclined surface 34a. Therefore, in order to prevent the setting block 74 from slipping on the inclined surface 34a and shifting out of position, the setting block 74 is fastened to the frame material 30b with a screw 79. The number of mounting holes 77 may be one or three or more. When the angle of the inclined surface 34a is gentle or when the mounting surface 75 can be adhesively fixed to the frame inner projection surface 34, the mounting holes 77 and the screws 79 may be omitted.

[0040] The holding portion 78 can support and hold the fin portion 60 of the covering material 32b. The holding portion 78 is a clip-shaped horizontal groove that opens onto the side surface of the setting block 74 facing the outside of the room, i.e., the side surface facing the covering material 32b. The holding portion 78 has a first support piece 78a on the upper side and a pair of second support pieces 78b, 78b on the lower side. The support pieces 78a, 78b have an arm shape that protrudes from the side surface.

[0041] The first support piece 78a is provided at the center in the width direction (X direction) of the setting block 74, and its upper surface also serves as the support surface 76. The second support pieces 78b are arranged on the left and right so as to straddle the first support piece 78a in the width direction, and their lower surfaces also serve as the placement surface 75. A slit 78c is formed at the boundary between the first support piece 78a in the center and the second support pieces 78b, 78b on the left and right. The slit 78c is narrow in the width direction of the support pieces 78a, 78b, and is long in the protruding direction (Z direction) of the support pieces 78a, 78b. This increases the effective protruding length of the support pieces 78a, 78b, allowing the support pieces 78a, 78b to elastically deform in the Y direction.

[0042] A downwardly protruding claw-shaped protrusion 78d is formed on the underside of the protruding end of the first support piece 78a. An upwardly protruding claw-shaped protrusion 78e is formed on the upper surface of the protruding end of the second support piece 78b. As a result, the second support piece 78b has a downwardly recessed recess 80 formed on the base end side (room side) of the protrusion 78e.

[0043] Here, the procedure for supporting the face material 26 using such a setting block 74 will be described. First, the setting block 74 is placed on the mounting surface 75 on the frame inner projection surface 34 and fixed to the frame material 30b with screws 79. Next, the fin portion 60 of the cover material 32b among the cover materials 32a to 32d connected around the four sides using the connecting metal fittings 68 is inserted into the holding portion 78. Then, the upper surface of the fin portion 60 is pressed downward by the first support piece 78a, and the lower surface is pressed upward by the second support piece 78b, and the fin portion 60 is sandwiched between the support pieces 78a and 78b. In particular, since the support pieces 78a and 78b have protrusions 78d and 78e at their respective tips, the fin portion 60 can be more reliably sandwiched by the protrusions 78d and 78e. At this time, the protrusions 60a at the tips of the fin portion 60 engage with the recesses 80. As a result, the fin portion 60 is supported in a state where it is prevented from slipping out to the outside of the room by the setting block 74. Finally, the lower end surface 26a of the face material 26 is supported on the support surface 76, thereby completing the support of the face material 26 by the setting block 74.

[0044] Next, the drainage structure of the lower frame 28b and its surrounding area will be described.

[0045] When the fitting 10 of this embodiment is subjected to rainwater or the like, the drainage water W, such as rainwater that falls on the outdoor surface of the inner screen 14, flows down the outdoor surface of the face material 26 and flows into the back side of the cover material 32b. The arrows shown by dashed lines in Figures 4 and 5 show the drainage path of the drainage water W. Note that although the batten 48 seals off the water between it and the face material 26 with a water-stopping material such as a specified gasket or waterproof material, it is not possible to completely prevent water from entering.

[0046] The wastewater W that flows into the back side of the cover material 32b first flows over the upper surface of the fin portion 60 and then flows onto the frame inner projection surface 34 of the frame material 30b. Here, the fin portion 60 is supported by the setting block 74 at the holding portion 78 between the placement surface 75 and the support surface 76. In other words, the fin portion 60 is in a floating state from the frame inner projection surface 34. For this reason, the wastewater W that flows down from the fin portion 60 to the frame inner projection surface 34 passes the side of the setting block 74 and smoothly flows below the fin portion 60, and flows down into the space S between the cover material 32b and the frame material 30b. At this time, the inclined surface 34a on the frame inner projection surface 34 allows the wastewater W to flow into the space S more smoothly. In addition, the notch 66 on the protruding piece 62b that constitutes the pocket portion 62 allows the wastewater W to flow through the space S more smoothly.

[0047] The wastewater W that has flowed down the space S then passes through the gap between the cover material 32b and the frame material 30b from the side of the bracket 72 and flows into the lower frame 12b. The wastewater W is then smoothly discharged to the outside through drainage holes formed in appropriate locations of the lower frame 12b.

[0048] As described above, in the fitting 10 of this embodiment, the cover material 32b covering the outside of the frame material 30b has a fin portion 60 protruding toward the frame material 30b side. This fin portion 60 is supported by the setting block 74 between the placement surface 75 and the support surface 76, based on the inside-outside direction (up-down direction) of the lower frame 28b.

[0049] In this way, in the fitting 10, the fin portion 60 of the cover material 32b is supported by the setting block 74 in a state where it is separated from the frame inner projection surface 34 of the frame material 30b. As a result, the cover material 32b can be supported on the frame material 30b via the setting block 74 in a state where the fin portion 60 is not in close contact with the frame material 30b. Therefore, the fin portion 60 is prevented from blocking the outflow path of the drainage water W from the frame inner projection surface 34, and the drainage water W that flows from the upper surface of the fin portion 60 to the frame inner projection surface 34 smoothly passes through the lower surface side of the fin portion 60 and is discharged to the outside of the room. As a result, the fitting 10 improves the drainage in the space between the cover material 32b and the frame material 30b, and maintains a dry state in the space. The fitting 10 can suppress decay of the wooden frame material 30b, and further suppresses the occurrence of hygiene problems caused by rainwater and the like accumulating in the space.

[0050] In addition, the inclined surface 34a is not essential for the fitting 10 because high drainage is ensured by the fin portion 60 not being in close contact with the frame inner visible surface 34. However, it goes without saying that the drainage is further improved if the inclined surface 34a is provided on the frame inner visible surface 34.

[0051] The setting block 74 may have a recess 80 into which the protrusion 60a of the fin portion 60 engages. This allows the setting block 74 to hold the fin portion 60 more securely, and more reliably prevents the cover material 32b from falling off to the outside of the room. Furthermore, by forming the recess 80 in the setting block 74, it is not necessary to provide a recess for the protrusion 60a to engage with the frame inner visible surface 34 of the frame material 30b as in the conventional configuration. This further improves drainage at the frame inner visible surface 34. The protrusion 60a and the recess 80 may be omitted, and instead the fin portion 60 may be fixed to the setting block 74 with screws or the like.

[0052] The setting block 74 may have a holding portion 78 that is provided on the side facing the cover material 32b and can hold the fin portion 60. In this case, the setting block 74 can hold the fin portion 60 more easily, improving the assembling of the fitting 10. In this case, the holding portion 78 may have a first support piece 78a that supports one side of the fin portion 60 and a second support piece 78b that supports the other side, which is the back side of the first side, and the fin portion 60 may be sandwiched and held between the support pieces 78a and 78b. In this case, the setting block 74 can hold the fin portion 60 more easily. Moreover, the support pieces 78a and 78b receive the weight of the face material 26 and apply a compressive force between them, so that the fin portion 60 can be more firmly held.

[0053] As described above, the fitting according to one aspect of the present invention is a fitting in which a surface material is supported by a frame body having a frame material and a cover material attached to the frame material, and is provided with a setting block having a placement surface that is placed on the inner frame surface of the frame material and a support surface that supports the lower end surface of the surface material, and the cover material has a fin portion that protrudes toward the frame material side, and the fin portion is supported by the setting block between the placement surface and the support surface. With this configuration, the fin portion of the cover material is supported by the setting block in a state where it is separated from the inner frame surface of the frame material. This makes it possible to prevent the fin portion from coming into close contact with the frame material, and improves the drainage of rainwater and the like that has flowed into the back space of the cover material.

[0054] The fin portion may have a protrusion protruding from one side, and the setting block may have a recess into which the protrusion engages. In this way, the fin portion can be more reliably held by the setting block, and drainage at the frame inner surface is further improved by not providing a recess on the frame inner surface of the frame material.

[0055] The setting block may have a holding portion that is provided on the side facing the cover material and is capable of holding the fin portion, which makes it easier to hold the fin portion on the setting block.

[0056] The holding portion may have a first support piece that supports one surface of the fin portion and a second support piece that supports the other surface of the fin portion, which is the reverse surface of the one surface, and the holding portion may be configured to hold the fin portion by sandwiching it between the first support piece and the second support piece. In this way, the weight of the face material can be used to more firmly sandwich the fin portion between the first and second support pieces.

[0057] The frame inner surface of the frame material may be configured to have an inclined surface that gradually slopes downward toward the cover material side, thereby further improving drainage at the frame inner surface.

[0058] The cover material may be provided with a ridge that presses the surface of the face material, so that the cover material also functions as the ridge, making it possible to reduce the number of parts.

[0059] The frame material may be made of wood and the cover material may be made of metal, which improves drainage and inhibits decay of the wooden frame material, and further protects the exterior surface of the wooden frame material with the metal cover material.

[0060] It should be noted that the present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention.

[0061] The inner sash 14 having the drainage structure described above may be used as a fixed window that is fitted into the opening frame 12. When the inner sash 14 is a fixed window, a frame body can be used instead of the frame body 26, for example, a frame body in which the frame material 18b constituting the lower frame 12b is integrally formed with the frame material 30b, and the cover material 20b constituting the lower frame 12b is integrally formed with the cover material 32b, and the face material 26 can be supported by this frame body. In this case, too, the face material 26 can be supported by the frame material formed by integrally forming the frame material 18b and the frame material 30b via the setting block 74, and the cover material formed by integrally forming the cover material 20b and the cover material 32b can be supported by the setting block 74.
