[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 sash 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 have a one-layer, two-layer, or four or more layer 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 configuration example of the cover materials 32a to 32d that constitute the frame 28 will be described.

[0026] As shown in FIG. 3, the cover materials 32a to 32d are connected in order to form a continuous frame shape around the four sides. That is, the longitudinal ends of the cover materials 32a, 32b of the upper and lower frames 28a, 28b are connected to the longitudinal ends of the cover materials 32c, 32d of the vertical frames 28c, 28d. Hereinafter, the cover materials 32a, 32b constituting the horizontal frames 28a, 28b are sometimes referred to as "horizontal cover materials 32a, 32b", and the frame materials 30a, 30b to which the horizontal cover materials 32a, 32b are attached are sometimes referred to as "horizontal frame materials 30a, 30b". Similarly, the cover materials 32c, 32d constituting the vertical frames 28c, 28d are sometimes referred to as "vertical cover materials 32c, 32d", and the frame materials 30c, 30d are sometimes referred to as "vertical frame materials 30c, 30d".

[0027] 3, the cover materials 32a to 32d of this embodiment have a so-called vertically connected structure in which the left and right ends of the horizontal cover materials 32a and 32b are connected to the upper and lower ends of the vertical cover materials 32c and 32d in a tangential manner. The horizontal cover materials 32a and 32b and the vertical cover materials 32c and 32d are connected to each other using connecting metal fittings 58.

[0028] In the following, as shown in Figures 4 to 7, the configurations and connecting structures of the horizontal cover material 32b and the vertical cover material 32c will be representatively described, and detailed descriptions of the configurations and connecting structures of the other cover materials 32a and 32d will be omitted. The configuration of the horizontal cover material 32a and the connecting structure with the vertical cover materials 32c and 32d can be the same as those of the horizontal cover material 32b, except that it is upside down (see Figure 1). Also, although the shape of the vertical cover material 32d is somewhat different from that of the vertical cover material 32c, the connecting structure with the horizontal cover materials 32a and 32b can be the same as that of the vertical cover material 32c, except that it is left-right reversed (see Figure 2).

[0029] 4 to 7, the horizontal cover material 32b is a metal extruded member that is thin in the projection direction (Z direction). The horizontal cover material 32b has a pressing edge 48, a fin portion 60, a pocket portion 62, and a claw portion 64.

[0030] 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 surface 34 of the frame material 30b (see FIG. 6). In this embodiment, the frame inner surface 34 of the frame material 30b is configured to have a gradient that slopes downward toward the outside of the room in consideration of drainage, but may be a flat surface. At the tip of the fin portion 60, a convex portion 60a that protrudes toward the lower surface side is bent and formed.

[0031] 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. 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 tips of the protrusions 62a, 62b are formed into an approximately U-shape with grooves facing each other. The pocket portion 62 functions as a pocket in which a member can be inserted and held by the space formed between the grooves of the protrusions 62a, 62b facing each other. The upper protrusion 62a is located in a position facing an R-shaped portion formed at the corner between the frame inner projection surface 34 and the outdoor facing surface 46 of the frame material 30b, for example. The lower protrusion 62b is located in a position facing the outdoor facing surface 46 of the frame material 30b. Although details will be described later, the pocket portion 62 has crimp fixing portions (fixing portions) 66 formed on parts of the protruding pieces 62a, 62b for fixing the position of the connecting fitting 58.

[0032] The protruding piece 62b may have a notch 67 (see FIG. 5) formed by cutting off a part of the protruding piece 62b at a position where the connecting metal fitting 58 is not installed. The notch 67 becomes part of a drainage path for rainwater and the like that has flowed in between the cover material 32b and the frame material 30b.

[0033] The claw portion 64 is formed on the indoor side of a hollow portion 68 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 70 is engaged with the claw portion 64. The bracket 70 is a member made by bending a metal plate such as stainless steel or steel. The other end of the bracket 70 is screwed to the lower surface (outer frame surface) of the frame material 30b. In other words, one end of the bracket 70, the other end of which is fixed to the frame material 30b, is engaged with the claw portion 64, so that the lower portions of the frame material 30b and the cover material 32b are positioned in the YZ direction. Reference numeral 71 in FIG. 3 denotes a cap that closes the small end of the hollow portion 68 on the vertical frame 28d side.

[0034] As shown in FIG. 6, the lower frame 28b supports the lower end surface 26a of the panel 26 with a setting block 72 placed on the frame inner projection surface 34 of the frame material 30b. The setting block 72 is molded from rubber or resin. The setting block 72 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 72 are provided in pair, for example, on the left and right sides in the longitudinal direction of the lower frame 28b (see FIG. 3). In this embodiment, the frame material 30b has a majority of the frame inner projection surface 34 formed as an inclined surface. For this reason, it is preferable to fix the setting block 72 to the frame material 30b with screws 73 (see FIG. 1).

[0035] The setting block 72 of this embodiment can support and hold the fin portion 60 of the cover material 32b. The setting block 72 has a clip-shaped horizontal groove that opens on the side surface facing the outside of the room. This horizontal groove is formed between the first support piece 72a on the upper side and the second support piece 72b on the lower side. The support pieces 72a and 72b have an arm shape that protrudes from the side surface and can be elastically deformed in the vertical direction. The setting block 72 can insert the fin portion 60 between the support pieces 78a and 78b and hold it. At this time, the convex portion 60a at the tip of the fin portion 60 engages with the concave portion 72c formed in the second support piece 72b. As a result, the fin portion 60 is supported by the setting block 72 in a state where it is held and prevented from slipping out to the outside of the room.

[0036] 4, 5 and 7, the vertical cover material 32c is a metal extrusion member that is thin in the projection direction (Z direction). The vertical cover material 32c has a pressing edge 48, a fin portion 74, and an engagement piece 76.

[0037] The fin portion 74 protrudes from the inner surface 77 of the cover material 32c toward the frame material 30c. The inner surface 77 faces the frame material 30c (inside the room). The fin portion 74 is provided on the outer side of the frame of the batten 48 in the view direction (X direction) of the cover material 32c, and extends over approximately the entire length of the cover material 32c. The fin portion 74 is a portion that abuts the end surface 78 of the horizontal cover material 32b. The fin portion 74 has a notch portion 74a at the end in the longitudinal direction, in which a part of the fin portion 74 is cut off to reduce the protruding length. As shown in FIG. 7, the joint portion 80 between the horizontal frame material 30b and the vertical frame material 30c is formed by, for example, a tenon joint. The notch portion 74a is a relief portion that prevents the fin portion 74 from interfering with the joint portion 80. The fin portion 74 is fixed to the frame inner surface 34 of the vertical frame material 30c by a screw 81 (see FIG. 2).

[0038] The fin portion 74 has a hole 82 formed through it in the plate thickness direction, and through which the connecting metal fitting 58 is inserted. The hole 82 is provided at a position in the longitudinal direction of the fin portion 74 where the horizontal cover material 32b abuts. A protrusion 83 is formed on the outdoor side of the hole 82, protruding from the frame outer visible surface of the fin portion 74. The details will be described later, but the edge of the hole 82 in the fin portion 74 functions as a locking portion 84 that locks the connecting metal fitting 58.

[0039] The engagement piece 76 protrudes from the outer frame end of the cover material 32c toward the frame material 30c. The engagement piece 76 engages with the end face of the frame material 30c to position the outer frame ends of the frame material 30c and the cover material 32c in the XZ directions. The engagement piece 76 is also formed on the horizontal cover material 32a of the upper frame 28a (see FIG. 1). Reference numeral 86 shown in FIG. 4 etc. is a cap that closes the small end of the vertical cover material 32c.

[0040] Next, the connection structure between the horizontal cover material 32b and the vertical cover material 32c using the connecting metal fitting 58 will be described.

[0041] 3 to 7, the connecting fitting 58 is a metal plate made of stainless steel, steel, or the like. The connecting fitting 58 is arranged along the XY directions and is a plate that is thin in the Z direction. This allows the connecting fitting 58 to be installed across the space S1 that is narrow in the Z direction between the horizontal cover material 32b and the horizontal frame material 30b, and the space S2 that is narrow in the Z direction between the vertical cover material 32c and the vertical frame material 30c.

[0042] The connecting fitting 58 has a tip portion 58a and a base portion 58b, and is generally T-shaped and oriented sideways when viewed from the front as shown in FIG.

[0043] The tip portion 58a is a portion that is inserted into and fixed to the pocket portion 62 in the space S1. The tip portion 58a is narrower in the Y direction than the base portion 58b. The tip portion 58a has a width in the Y direction and a plate thickness in the X direction that allows it to be inserted into a hole portion 82 formed in the fin portion 74 of the vertical cover material 32c. A pair of chamfered portions are provided in the Y direction at the tip corners of the tip portion 58a to facilitate smooth insertion into the hole portion 82 and the pocket portion 62.

[0044] A notched receiving portion 58c is formed on the upper and lower edges of the tip 58a extending along the X direction. A crimp fixing portion 66 formed on the protrusions 62a, 62b fits into each receiving portion 58c. The receiving portion 58c may have a shape other than a notched shape as long as it is structured to be able to fit the crimp fixing portion 66. For example, the receiving portion 58c may be formed as a recess formed by recessing the interior side surface of the tip 58a, or as a hole formed by boring the tip 58a in the plate thickness direction.

[0045] The base portion 58b is a portion that is locked by the edge (locking portion 84) of the hole portion 82 in the space S2. The base portion 58b is wider in the Y direction than the tip portion 58a. The base portion 58b has a width in the Y direction that prevents it from being inserted through the hole portion 82.

[0046] The base 58b may have a configuration other than that of having a larger width in the Y direction than the tip 58a, so long as it can be locked by the locking portion 84. For example, the base 58b may have a configuration in which the width in the Y direction is the same as that of the tip 58a, but the plate thickness in the X direction is larger than the width in the X direction of the hole 82, or a protrusion protruding in the plate thickness direction is provided so that the base 58b can be locked to the edge of the hole 82. However, a configuration in which the plate thickness of the base 58b is larger than that of the tip 58a or a protrusion is provided not only reduces the manufacturing efficiency of the connecting fitting 58, but may also require the expected dimension of the space S2 to be increased. Therefore, it is preferable that the base 58b has a configuration in which the plate thickness is the same as that of the tip 58a, but only the width in the Y direction is increased, as in the configuration example shown in FIG. 5.

[0047] Here, one procedure of the method of connecting the horizontal cover material 32b and the vertical cover material 32c using the connecting metal fitting 58 will be described. First, as shown in FIG. 5, the end of the horizontal cover material 32b is tucked into the vertical cover material 32c, and the end surface 78 is abutted against the fin portion 74. Next, the tip portion 58a of the connecting metal fitting 58 is inserted into the hole portion 82 from the outside of the frame and inserted into the pocket portion 62. Then, the base portion 58b of the connecting metal fitting 58 is engaged with the engaging portion 84, which is the edge of the hole portion 82, and the movement toward the horizontal cover material 32b is restricted. Then, the member constituting the pocket portion 62, that is, a part of the indoor side plate piece of the protruding pieces 62a, 62b is crushed toward the outdoor side and crimped to the receiving portion 58c of the connecting metal fitting 58. As a result, the crimp fixing portion 66 fits into the receiving portion 58c, and the position of the connecting metal fitting 58 in the XYZ directions relative to the horizontal cover material 32b is fixed. As a result, the cover materials 32b and 32c are connected by the connecting metal fitting 58. At this time, since the vertical cover material 32c has a protrusion 83 on the outdoor side of the hole 82, the connecting metal fitting 58 does not rattle in the space S2 (see FIG. 7). The protrusion 83 can also guide the insertion of the tip 58a into the hole 82.

[0048] As described above, the connecting structure between the horizontal cover material 32b and the other vertical cover material 32d, and the connecting structure between the other horizontal cover material 32a and the vertical cover materials 32c, 32d may be similar to the connecting structure between the horizontal cover material 32b and the vertical cover material 32c described above. Therefore, for these connecting structures, the same reference numerals as those used in the connecting structure between the horizontal cover material 32b and the vertical cover material 32c in Fig. 3 are used, and detailed explanations are omitted.

[0049] Next, a procedure for assembling the inner screen 14 by mounting the cover materials 32a to 32d connected using such connecting fittings 58 to the frame materials 30a to 30d will be described.

[0050] First, the cover materials 32a to 32d are connected around all four sides using the connecting metal fittings 58 to form a frame shape. At the same time, the frame materials 30a to 30d are also connected around all four sides to form a frame shape. The method of connecting the cover materials 32a to 32d with the connecting metal fittings 58 is as described above. The frame materials 30a to 30d can be appropriately connected using the joint portion 80 or a similar joint structure, etc.

[0051] Next, the cover materials 32a-32d connected around the four sides are attached to the frame materials 30a-30d connected around the four sides. In the lower frame 28b, the fin portion 60 of the horizontal cover material 32b is inserted between the support pieces 72a, 72b of the setting block 72 fixed to the frame inner projection surface 34 of the horizontal frame material 30b and held. Furthermore, the bracket 70 fixed to the frame outer projection surface of the horizontal frame material 30b is supported by the claw portion 64. In the upper frame 28a, the fin portion 60 of the horizontal cover material 32a is screwed to the frame inner projection surface 34 of the horizontal frame material 30a, and the engagement piece 76 is engaged with the frame outer projection surface of the horizontal frame material 30b. In the vertical frame 28c, the fin portion 74 of the vertical cover material 32c is screwed to the frame inner projection surface 34 of the vertical frame material 30c, and the engagement piece 76 is engaged with the frame outer projection surface of the vertical frame material 30c. In the vertical frame 28d, the fin portion 74 of the vertical cover material 32d is screwed to the inner frame surface 34 of the vertical frame material 30d, and the end of the vertical cover material 32d is screwed to the outdoor surface 46 of the vertical frame material 30d (see Figure 2).

[0052] Next, the face material 26 is supported. The face material 26 is inserted from the indoor side into the opening within the frame of the frame body 28, which has the cover materials 32a-32d attached to the frame materials 30a-30d. The face material 26 is then pressed against the ridges 48 of the cover materials 32a-32d via a predetermined waterproofing material. Next, the ridges 36 are attached to the frame inner projection surfaces 34 of the frame materials 30a-30d. As a result, the indoor and outdoor surfaces of the face material 26 are held by the ridges 36, 48, the face material 26 is supported by the frame body 28, and the assembly of the inner sash 14 is completed.

[0053] As described above, the fitting 10 of this embodiment is disposed so as to straddle between the horizontal covering materials 32a, 32b and the horizontal frame materials 30a, 30b (space S1) and between the vertical covering materials 32c, 32d and the vertical frame materials 30c, 30d (space S2), and is provided with the connecting metal fittings 58 that connect the horizontal covering materials 32a, 32b and the vertical covering materials 32c, 32d. Here, the vertical covering materials 32c, 32d have the locking portions 84 that lock the connecting metal fittings 58 and restrict movement toward the horizontal covering materials 32a, 32b. The horizontal covering materials 32a, 32b have fixing portions (rivet fixing portions 66) that fix the position of the connecting metal fittings 58.

[0054] In the fitting 10, the horizontal cover materials 32a, 32b covering the horizontal frame materials 30a, 30b and the vertical cover materials 32c, 32d covering the vertical frame materials 30c, 30d are connected by a connecting metal fitting 58 installed so as to straddle the spaces S1, S2. Therefore, the cover materials 32a to 32d do not need to secure installation space on their back sides (inner surfaces 65, 77 sides) for screws to connect adjacent ones to each other. Therefore, the fitting 10 can make the expected dimensions of the cover materials 32a to 32d as thin as possible, and can reduce material costs. Furthermore, the fitting 10 can reduce the expected dimensions of the frame 28, and as a result, the expected dimensions of the fitting 10 itself can be reduced, making it possible to slim down the window.

[0055] Particularly in the present embodiment, the frame members 30a-30d are made of wood, and the cover members 32a-32d are made of metal. Therefore, the wooden frame members 30b-30d tend to be thicker than frame members made of shaped materials made of metal such as aluminum, making it even more important to make the cover members 32a-32d thinner. In this respect, the door and window 10 uses the connecting metal fittings 58 as described above, which makes it possible to reduce the thickness of the cover members 32a-32d, and is therefore even more advantageous as a window using wooden frame members 30a-30d.

[0056] Moreover, in a configuration in which the cover materials are fastened together with screws, the cover materials rotate relative to each other when the screws are fastened, reducing the flatness of the connecting surfaces of the cover materials, which may cause problems with watertightness at those points. In this regard, the fitting 10 of this embodiment uses connecting metal fittings 58 that do not require screw fastening to connect the cover materials 32a-32d, so this type of problem can be avoided. The connection of the cover materials 32a-32d with connecting metal fittings 58 may be applied to only some of the four corners.

[0057] The horizontal cover members 32a and 32b have pockets 62 extending along their longitudinal direction and into which the connecting fittings 58 are inserted, and the fixing parts may include rivet fixing parts 66 formed by rivet-fixing the members (projections 62a and 62b) that form the pockets 62 to the connecting fittings 58 inserted into the pockets 62. In this case, screws are not required to fix the positions of the horizontal cover members 32a and 32b and the connecting fittings 58, and the expected dimensions and material costs can be reduced. Furthermore, the connecting fittings 58 can be easily positioned in the X direction by the rivet fixing parts 66 when positioned in the YZ directions by the pockets 62, and the structure can be simplified. The fixing parts that fix the positions of the connecting fittings 58 in the horizontal cover members 32a and 32b may be other than the rivet fixing parts 66, and it is also possible to use fasteners smaller than normal screws, such as press-fit pins and set screws.

[0058] The vertical cover materials 32c, 32d may have fin portions 74 extending along the longitudinal direction thereof and holes 82 formed through the fin portions 74, and the locking portions 84 may include edges of the holes 82. In this case, the connecting fittings 58 may have a tip portion 58a that is fixed to the horizontal cover materials 32a, 32b by the crimp fixing portions 66 in a state where the connecting fittings 58 are inserted through the holes 82 and inserted into the pocket portions 62, and a base portion 58b that is formed wider than the tip portion 58a and is locked by the locking portions 84. In this case, the connecting fittings 58 can be configured to have a reduced thickness so as not to hinder the thinning of the cover materials 32a to 32d, and can be locked to the vertical cover materials 32c, 32d with a simpler structure.

[0059] Next, the connection structure of the cover materials 32a to 32d using a connecting metal fitting 88 according to a modified example will be described with reference to Figures 8 and 9. In Figures 8 and 9, the same reference symbols as those shown in Figures 1 to 7 indicate the same or similar configurations, and therefore detailed descriptions will be omitted assuming that they have the same or similar functions and effects. Also, in this modified example, the configurations of the horizontal cover material 32b of the lower frame 28b and the vertical cover material 32c of the vertical frame 28c and the mutual connection structure will be representatively described, and detailed descriptions of the configurations and connection structures of the other cover materials 32a, 32d will be omitted.

[0060] As shown in Figs. 8 and 9, the connecting fitting 88 is a metal plate formed in a substantially U-shape when viewed from the front. The tip 58a of the connecting fitting 88 is bifurcated. That is, the connecting fitting 88 has a pair of tip parts 58a, 58a in the Y direction. The base part 58b of the connecting fitting 88 is a part that connects the bifurcated tip parts 58a, 58a to each other, and is a bridge part extending in the Y direction. As shown in Fig. 8, the horizontal cover material 32b using the connecting fitting 88 has a pair of pocket parts 62, 62 in the Y direction. Each tip part 58a is inserted into each pocket part 62, and fixed by a crimp fixing part 66. The end surface 58d of the base part 58b facing the tip side of the tip part 58a at a position sandwiched between the pair of tip parts 58a, 58a is engaged with an engaging part 84 of the vertical cover material 32c described later.

[0061] 8 illustrates a structure in which the horizontal covering material 32b is not connected to the vertical covering material 32c by a spigot structure, but rather an end face 78 of the horizontal covering material 32b is butted against the surface of the edge 48 that forms the inner frame surface of the vertical covering material 32c. For this reason, the vertical covering material 32c shown in FIG. 8 employs a structure in which the base 58b of the connecting metal fitting 88 is locked by the edge 48 that stands up from the inner frame end of the inner surface 77 toward the room side, instead of the fin portion 74.

[0062] Specifically, the pressing edge 48 of the vertical cover material 32c has a pair of notches 48a, 48a formed by cutting off a portion of the portion where the two tip portions 58a are to be installed. The pressing edge 48 has a base portion where the tip side is cut off by these notches 48a, that is, a fin portion 48b (see also Figs. 2 and 4) that stands up from the frame inner end of the inner surface 77 toward the room side. A pair of holes 82 are provided for the fin portion 48b. In these vertical cover materials 32c, the edge between the holes 82, 82, that is, the fin portion 48b located between the holes 82, 82, functions as a locking portion 84 that locks the end surface 58d of the base portion 58b.

[0063] When connecting the horizontal cover material 32b and the vertical cover material 32c using such a connecting metal fitting 88, first, as shown in FIG. 8, the end surface 78 of the horizontal cover material 32b is butted against the pressing edge 48 (fin portion 48b) of the vertical cover material 32c. At this time, it is preferable to provide a waterproofing material 90 at the boundary between the end surface 78 and the fin portion 48b, that is, between the connecting surfaces of the cover materials 32b and 32c. The waterproofing material 90 is, for example, a sealer. That is, the configuration example shown in FIG. 8 is different from the inro structure shown in FIG. 1 to FIG. 7 in that the connecting surfaces of the cover materials 32b and 32c are exposed to the outside of the room, and therefore waterproofing becomes a problem. Therefore, in this configuration example, the waterproofing material 90 is provided to stop water from flowing between the connecting surfaces of the cover materials 32b and 32c. Of course, the waterproofing material 90 may be applied to the above-mentioned inro structure configuration example.

[0064] Next, the two tips 58a of the connecting fitting 88 are inserted into the holes 82 from the outside of the frame, and inserted into each pocket 62. Then, the base 58b of the connecting fitting 88 is engaged with the engaging portion 84, which is the edge sandwiched between the holes 82, 82, and the movement toward the horizontal cover material 32b is restricted. Then, the members constituting each pocket 62, that is, a part of the indoor side plate of the protruding pieces 62a, 62b, is crushed toward the outdoor side and crimped to the receiving portion 58c of the connecting fitting 88. As a result, the crimp fixing portion 66 fits into the receiving portion 58c, and the position of the connecting fitting 88 in the XYZ directions relative to the horizontal cover material 32b is fixed. As a result, the covering materials 32b, 32c are connected by the connecting fitting 88. At this time, since the vertical cover material 32c has the engaging portion 84 between the pair of holes 82, 82, the connecting fitting 88 does not rattle in the space S2.

[0065] In the configuration using the connecting fitting 88, the expected dimensions of the cover materials 32a-32d can be made thinner, and material costs can be reduced, as in the configuration using the connecting fitting 58 described above. The connecting fitting 88 has a more complicated structure than the connecting fitting 58, but has the advantage that the connecting strength of the cover materials 32a-32d is improved compared to the connecting fitting 58 by having a pair of tip portions 58a fixed to the horizontal cover materials 32a, 32b. Such a connecting fitting 88 may be applied to the example of the inro structure described above.

[0066] In the above-mentioned configuration examples, the cover materials 32a to 32d have a so-called vertically-supported structure. For this reason, the horizontal cover materials 32a and 32b are provided with pockets 62 and fixing parts (crimp fixing parts 66), the vertical cover materials 32c and 32d are provided with locking parts 84, and the connecting metal fittings 58 and 88 are configured to have their tips 58a installed horizontally. However, in the fitting 10, the cover materials 32a to 32d may have a so-called horizontally-supported structure in which the ends of the vertical cover materials 32c and 32d are inverted or butted against the frame inner projection surface of the horizontal cover materials 32a and 32b. In the case of this horizontally-supported structure, the vertical cover materials 32c and 32d are provided with pockets 62 and fixing parts (crimp fixing parts 66), the horizontal cover materials 32a and 32b are provided with locking parts 84, and the connecting metal fittings 58 and 88 are configured to have their tips 58a installed vertically.

[0067] As described above, a fixture according to one aspect of the present invention is a fixture comprising a horizontal frame material, a vertical frame material, a horizontal covering material attached to the horizontal frame material, and a vertical covering material attached to the vertical frame material, and is provided with connecting fittings arranged to straddle between the horizontal covering material and the horizontal frame material and between the vertical covering material and the vertical frame material, connecting the horizontal covering material and the vertical covering material, one of the horizontal covering material and the vertical covering material has a locking portion that locks the connecting fitting to restrict the connecting fitting from moving toward the other covering material, and the other covering material has a fixing portion that fixes the position of the connecting fitting. With this configuration, the horizontal covering material and the vertical covering material are connected by the connecting fittings, so that each covering material can be made thinner.

[0068] The other cover material may have a pocket portion extending along its longitudinal direction and into which the connecting fitting is inserted, and the fixing portion may include a crimp fixing portion formed by crimping a member forming the pocket portion to the connecting fitting inserted into the pocket portion. In this way, the positional fixing of the other cover material and the connecting fitting can be simplified, and the expected dimensions and material costs of the cover material can be further reduced.

[0069] The one cover material may have a fin portion extending along its longitudinal direction and a hole portion formed through the fin portion, the locking portion includes an edge of the hole portion, and the connecting fitting may have a tip portion fixed to the other cover material by the crimp fixing portion in a state where the connecting fitting is inserted through the hole portion and inserted into the pocket portion, and a base portion formed wider than the tip portion and locked by the locking portion. In this way, the connecting fitting can be made thinner and simpler in configuration, while being reliably locked by the locking portion.

[0070] The horizontal frame material and the vertical frame material may be made of wood, and the horizontal cover material and the vertical cover material may be made of metal. In this way, while using wooden frame material, which tends to be thicker than frame material formed from metal shaped members, it is possible to reduce the total thickness of the frame material and the cover material by making the cover material thinner, thereby reducing the disadvantages of wooden frame material.

[0071] A waterproof material may be provided between the connecting surfaces of the horizontal cover material and the vertical cover material, thereby improving the waterproof performance between the cover materials.

[0072] 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.

[0073] The inner sash 14 using the above-mentioned connecting fittings 58, 88 may be used as a fixed window that is fitted into the opening frame 12. The connecting fittings 58, 88 may also be applied to a frame other than a frame that supports a panel, i.e., a frame such as the opening frame 12. [Explanation of symbols]
