Description

Technical Field

[0001] The present invention relates to a shoji fixing tool for fixing a frame and a shoji, and a fitting provided with the shoji fixing tool.

Background Art

[0002] As a window for a building or a house, there is a casement window having a structure in which a shoji is rotatably supported with respect to a frame. Examples of the casement window include a projecting window having a hinge attached to the upper frame of the shoji and an outward-opening window having a hinge attached to the lower frame of the shoji.

[0003] This type of fitting is transported from a factory or the like to a construction site after rotatably attaching a shoji to a frame. At the site, after fixing the fitting to the building frame, glass is assembled, and then an opening / closing device such as a damper is attached between the shoji and the frame. Therefore, it is necessary to fix the shoji to the frame in the closed position until the opening / closing device is attached after being transported from a factory or the like. This is to prevent the shoji from opening / closing unintentionally due to the impact during transportation or the wind pressure, and to prevent damage to the shoji and the frame. For example, Patent Document 1 discloses a shoji holding member for holding a shoji to a frame.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, preferred embodiments of the shoji fixture and the fitting according to the present invention will be described in detail with reference to the accompanying drawings.

[0012] As shown in FIGS. 1 to 3, a fitting 10 according to an embodiment includes a frame body 12 fixed to an opening of a building body, and a shoji 14 rotatably supported inside the frame body 12. In this embodiment, the fitting 10 of a projecting window in which the shoji 14 rotates with the upper edge as a rotation fulcrum and the lower edge projecting toward the outdoor side is exemplified. The fitting 10 is, for example, a smoke exhaust window installed in a building or a house. The fitting according to the present application may be other than a projecting window, for example, an outward-opening window, an inward-opening window, a sliding window, a vertical sliding window, etc., and may be used for purposes other than a smoke exhaust window.

[0013] The frame body 12 forms a rectangular opening 16 inside by surrounding an upper frame 12a, a lower frame 12b, and left and right vertical frames 12c and 12d to form a four-sided frame.

[0014] In the present 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 reverse direction (the direction indicated by the arrow Z in the figure), and the prospective plane refers to a plane extending along the prospective direction. The finding direction is a direction orthogonal to the prospective direction. In the case of a vertically long vertical frame 12c or the like, it refers to the left-right direction (the direction indicated by the arrow X in the figure) orthogonal to its longitudinal direction. In the case of a horizontally long upper frame 12a or the like, it refers to the up-down direction (the direction indicated by the arrow Y in the figure) orthogonal to its longitudinal direction. The finding plane refers to a plane along the finding direction. The inside of the frame refers to the inner part of the frame-shaped member such as the frame body 12. The outside of the frame refers to the outer part of the frame-shaped member such as the frame body 12. The in-frame direction refers to the direction from the outside of the frame of the frame-shaped member toward the inside of the frame. The out-frame direction refers to the direction from the inside of the frame of the frame-shaped member toward the outside of the frame.

[0015] The frame body 12 is a window frame with a composite structure combining a metal frame member 18 arranged on the outdoor side and a resin frame member 19 arranged on the indoor side. The metal frame member 18 is an extruded profile of a metal material such as an aluminum alloy. The resin frame member 19 is an extruded profile of a resin material such as vinyl chloride resin (PVC). The metal frame member 18 includes a metal upper frame 18a, a metal lower frame 18b, and left and right metal vertical frames 18c, 18d. The resin frame member 19 includes a resin upper frame 19a, a resin lower frame 19b, and left and right resin vertical frames 19c, 19d.

[0016] As shown in FIG. 2, the upper frame 12a has a configuration in which the resin upper frame 19a is connected to the indoor side of the metal upper frame 18a. The resin upper frame 19a covers the indoor side surface of the metal upper frame 18a. The metal upper frame 18a has a predetermined anchor part connected to an anchor mounting part 20 formed on the prospective surface on the outer side of the frame, and is fixed to the building body through this anchor part. The resin upper frame 19a is connected to the metal upper frame 18a by, for example, a pair of engaging parts 22a, 22b, and the indoor side end is fixed to the building body with a screw 23.

[0017] The metal upper frame 18a is provided with a door stop piece 26 at the indoor side end of the prospective surface 24 inside the frame, and a drain member 27 is attached to the outdoor side end of the prospective surface 24. The door stop piece 26 is a plate piece protruding from the prospective surface 24 inside the frame (downward). The door stop piece 26 is a part for receiving the shoji 14 in the fully closed position shown in FIG. 2. A pocket part opening toward the outdoor side is provided at the tip of the door stop piece 26, and a tight material 28 is attached to this pocket part. The tight material 28 is an airtight and watertight material for ensuring the airtightness and watertightness in the indoor-outdoor direction of the opening 16 by closely adhering to the indoor side surface of the shoji 14. The drain member 27 is attached to a pocket part formed on the prospective surface 24 and opening downward, and can contact the upper end of the shoji 14.

[0018] The resin upper frame 19a covers the surface of the door stop piece 26 of the metal upper frame 18a and the surface of the part on the indoor side thereof. The resin upper frame 19a has a hollow part 29 at a position aligned with the indoor side of the door stop piece 26.

[0019] As shown in FIG. 2, the lower frame 12b is configured by connecting a resin lower frame 19b to the indoor side of a metal lower frame 18b. The resin lower frame 19b covers the indoor side surface of the metal lower frame 18b. The metal lower frame 18b has a predetermined anchor component connected to an anchor attachment portion 30 formed on the prospective surface outside the frame, and is fixed to the building structure through this anchor component. The resin lower frame 19b is connected to the metal lower frame 18b by, for example, a pair of engagement portions 32a, 32b, and the indoor side end portion is fixed to the building structure with screws 23.

[0020] The metal lower frame 18b is provided with a door stop piece 36 at the indoor side end portion of the prospective surface 34 inside the frame. The door stop piece 36 is a plate piece protruding from the prospective surface 34 toward the inside (upward) of the frame. The door stop piece 36 is a portion that receives the shoji 14 in the fully closed position shown in FIG. 2. A pocket portion that opens toward the outdoor side is provided at the tip of the door stop piece 36, and a tight material 28 is attached to this pocket portion.

[0021] The resin lower frame 19b covers the upper end surface of the door stop piece 36 of the metal lower frame 18b and the portion on the indoor side thereof. The lower frame 12b has a hollow portion 37 formed by the metal lower frame 18b and the resin lower frame 19b on the indoor side of the door stop piece 36. A part of the wall portion surrounding the hollow portion 37 is formed by the metal lower frame 18b, and the rest is formed by the resin lower frame 19b.

[0022] As shown in FIG. 3, one vertical frame 12c is configured by connecting a resin vertical frame 19c to the indoor side of a metal vertical frame 18c. The resin vertical frame 19c covers the indoor side surface of the metal vertical frame 18c. The metal vertical frame 18c has a predetermined anchor component connected to an anchor attachment portion 38 formed on the prospective surface outside the frame, and is fixed to the building structure through this anchor component. The resin vertical frame 19c is connected to the metal vertical frame 18c by, for example, a pair of engagement portions 40a, 40b, and the indoor side end portion is fixed to the building structure with screws 23.

[0023] The metal vertical frame 18c is provided with a door-stop piece 44 at the indoor-side end of the prospective surface 42 inside the frame. The door-stop piece 44 is a plate piece protruding inward from the prospective surface 42. The door-stop piece 44 is a portion that receives the shoji 14 in the fully closed position shown in FIG. 3. A pocket portion that opens toward the outdoor side is provided at the tip of the door-stop piece 44, and the tight material 28 is attached to this pocket portion.

[0024] The resin vertical frame 19c covers the surface of the door-stop piece 44 of the metal vertical frame 18c and the surface of the portion on the indoor side thereof. The resin vertical frame 19c has a hollow portion 45 at a position aligned with the indoor side of the door-stop piece 44.

[0025] As shown in FIG. 3, the other vertical frame 12d can have a structure symmetrical to the one vertical frame 12c. Therefore, the same reference numerals are given to the respective components of the vertical frame 12d as those of the respective components of the vertical frame 12c, and detailed description thereof is omitted. That is, also in the vertical frame 12d, the resin vertical frame 19d is connected to the metal vertical frame 18d by the engaging portions 40a and 40b. The vertical frame 12d also has a door-stop piece 44 with the tight material 28 attached to the indoor-side end of the prospective surface 24, and the resin vertical frame 19d has a hollow portion 45.

[0026] As shown in FIGS. 1 to 3, the shoji 14 includes a face material 46, a frame body 47 that surrounds the four circumferences of the face material 46, and a pressing edge 48.

[0027] The face material 46 is, for example, a two-layer laminated glass in which a pair of plate glasses 46a and 46b face each other with a spacer sandwiched therebetween. The face material 46 may be a single layer or may have a structure of three or more layers.

[0028] The frame body 47 supports the facing material 46 inside by forming a four-sided frame structure with the upper frame 47a, the lower frame 47b, and the left and right vertical frames 47c and 47d. On the outdoor-side ends of the prospective surfaces 50 inside the frames 47a to 47d, there are locating pieces 51 provided. The locating pieces 51 are plate pieces protruding from the prospective surfaces 50 toward the inside of the frames. The locating pieces 51 are parts that support the outdoor-side surface of the facing material 46. The vertical frames 47c and 47d have locating pieces protruding outward from the outdoor-side ends of the prospective surfaces 52 outside the frames, and a drain material 53 is attached to the pocket parts formed on these locating pieces. The tip of the drain material 53 can contact the prospective surfaces 42 inside the frames of the vertical frames 12c and 12d.

[0029] The frames 47a to 47d are extruded profiles made of a metal material such as an aluminum alloy. In this embodiment, the upper frame 47a and the lower frame 47b have a vertically symmetric structure, and the vertical frames 47c and 47d have a horizontally symmetric structure. The frames 47a to 47d may each have different cross-sectional shapes, or all the frames 47a to 47d may have the same cross-sectional shape.

[0030] The edge retainers 48 are respectively attached to the indoor-side of the prospective surfaces 50 of each of the frames 47a to 47d. The edge retainers 48 are members that support the indoor-side surface of the facing material 46. That is, the fitting 10 of this embodiment has an inner-edge-retaining structure in which the edge retainers 48 are attached to the frame body 47 from the indoor side to support the indoor-side surface of the facing material 46. The facing material 46 is held via a gasket or a sealing material or the like in a state where the four peripheral edges are inserted into the opening grooves formed by the locating pieces 51, the edge retainers 48, and the prospective surfaces 50.

[0031] The edge retainers 48 include a metal edge retainer 48a and a resin edge retainer 48b. The metal edge retainer 48a is an extruded profile made of a metal material such as an aluminum alloy. The resin edge retainer 48b is an extruded profile made of a resin material such as polyvinyl chloride resin (PVC). The metal edge retainer 48a is connected to the prospective surfaces 50 of the frames 47a to 47d using the engaging part 54. The resin edge retainer 48b is connected to the metal edge retainer 48a and the prospective surface 50 by a pair of engaging parts 55a and 55b. The edge retainers 48 are configured to simultaneously hold the indoor-side surface of the facing material 46 with the metal edge retainer 48a and the resin edge retainer 48b arranged in the frame-inner and -outer direction.

[0032] As shown in FIGS. 1 to 3, the shoji 14 is rotatably connected to the frame body 12 via a hinge 60. The hinge 60 is connected to the prospective surface 24 inside the frame of the upper frame 12a and the prospective surface 58 outside the frame of the upper sash 47a. The reference numeral 61 in FIGS. 1 and 2 is a wire-type shoji opening / closing device provided between the frame body 12 and the shoji 14, and the shoji 14 can be opened and closed by operating an operation box having an operation button and an operation handle. The shoji opening / closing device 61 has, for example, a cable 61a, a cable guide 61b, a turning pulley 61c, and a pulley 61d. The cable 61a connects, for example, the operation box and the wire. The turning pulley 61c is a pulley that changes the direction of the wire. The pulley 61d is supported by the frame body 12 and the shoji 14, respectively, and a wire for opening and closing the shoji 14 is spanned therebetween. The reference numeral 62 in FIGS. 1 and 3 is a stay damper that biases the shoji 14 in the opening direction with respect to the frame body 12.

[0033] Incidentally, the fitting 10 is a casement window that rotatably supports the shoji 14 with respect to the frame body 12. The fitting 10 is assembled in a factory or the like and transported to the construction site. In a state until it is attached to the building frame, the facing material 46, the shoji opening / closing device 61, and the stay damper 62 are not attached. That is, in the fitting 10 in this state, only the sash 47 of the shoji 14 is rotatably supported by the hinge 60 on the frame body 12 (see FIG. 4).

[0034] The facing material 46 is attached after fixing the fitting 10 in this state to the building frame. The shoji opening / closing device 61 and the stay damper 62 are attached after assembling the facing material 46 to the shoji 14. This is to prevent the facing material 46 from being damaged during transportation or the frame body 12 and the sash 47 from being deformed by the load generated when attaching the shoji opening / closing device 61 and the stay damper 62. The pressing edge 48 may be temporarily attached to the sash 47 in a factory or the like, removed once during the assembly of the facing material 46 at the construction site, and then reattached, or may be attached for the first time after assembling the facing material 46 to the sash 47 at the construction site.

[0035] As described above, until the fitting 10 is assembled at a factory or the like and the shoji opening / closing device 61 or the like is attached at the construction site (during the curing period), the shoji 14 is in a state of being rotatable freely with respect to the frame body 12 via the hinge 60. For this reason, in the fitting 10, the shoji 14 is not stable during transportation or before and after fixing to the building frame, and there is also a concern that it may open and close due to wind pressure or the like and be damaged. Therefore, the fitting 10 includes a shoji fixing tool 64 for temporarily fixing the shoji 14 to the frame body 12 during the curing period (see FIG. 4).

[0036] Next, the configuration of the shoji fixing tool 64 and the method of fixing the shoji 14 by the shoji fixing tool 64 will be described.

[0037] As shown in FIG. 4, in the fitting 10, the upper frame 12a and the upper sash 47a are connected by the hinge 60. The shoji fixing tool 64 is installed so as to fix the lower frame 12b and the lower sash 47b (see also FIG. 1). Hereinafter, regarding the shoji fixing tool 64, based on the posture and direction in which the lower frame 12b and the lower sash 47b are fixed as shown in FIG. 4, the arrangement and structure of its components will be described.

[0038] As shown in FIGS. 4 to 7B, the shoji fixing tool 64 is a sheet metal part formed by bending a metal plate such as stainless steel or steel. The shoji fixing tool 64 has a frame side plate portion 64a, a standing plate portion 64b, a shoji side plate portion 64c, an operation portion 65, a long hole 66, and a slit portion 67.

[0039] The frame side plate portion 64a is a flat plate along the expected direction, and is arranged opposite to the expected surface 34 of the lower frame 12b in a state of being in contact with or close to it. The standing plate portion 64b is a flat plate bent upward from the outdoor side end portion of the frame side plate portion 64a. The shoji side plate portion 64c is a flat plate bent inward from the upper end portion of the standing plate portion 64b along the expected direction, and is arranged opposite to the expected surface 58 of the lower sash 47b.

[0040] The operation part 65 is composed of a finding plate part 64d and a prospect plate part 64e. The finding plate part 64d is a flat plate part bent upward from the indoor-side end of the shoji side plate part 64c. The prospect plate part 64e is a flat plate bent from the upper end of the finding plate part 64d toward the indoor side and along the prospect direction. The operation part 65 is a part that an operator operates with fingertips or the like when sliding the shoji fixture 64 in the X direction as described later.

[0041] As shown in FIG. 4, the finding plate part 64d is provided so as to extend in the frame inward direction between the finding surface 68 on the outdoor side of the lower frame 12b and the finding surface 69 on the indoor side of the lower frame 47b. The finding surface 68 is the finding surface of the door stop piece 36. That is, the finding plate part 64d is arranged so as to pass between the door stop piece 36 and the tight material 28 provided at the upper end thereof and the finding surface 69 of the lower frame 47b which is the contact target of the tight material 28. A cushion material 70 is attached to the outdoor-side surface of the finding plate part 64d. The cushion material 70 is, for example, a thin rubber sheet or a sponge sheet. The cushion material 70 prevents the lower frame 47b from being damaged due to the contact between the finding plate part 64d and the finding surface 69 of the lower frame 47b, and can also suppress the generation of abnormal sounds and the like.

[0042] The expected plate portion 64e is installed so as to be located outside the frame of the frame body 12 in the inner frame direction of the frame, relative to the installation surface 71 of the facing material 46. In the case of the fitting 10 of the present embodiment, the lower end surface 46c of the facing material 46 is placed on the upper surface of a setting block SB placed on the expected surface 50 of the lower frame 47b. Accordingly, the installation surface 71 becomes the upper surface of the setting block SB, and the expected plate portion 64e is arranged below the installation surface 71 and the lower end surface 46c of the facing material 46. Here, a flat surface 72 is provided on the lower frame 12b on the indoor side of the shoji 14. The flat surface 72 is the expected surface on the inner side of the frame of the lower frame 12b located on the indoor side of the tight material 28, and in the present embodiment, it is the expected surface on the inner side of the resin lower frame 19b. The expected plate portion 64e is arranged along the flat surface 72. Thereby, the expected plate portion 64e can be smoothly arranged below (outside the frame) the installation surface 71, and further smooth sliding in the X direction becomes possible. A cushion material 70 is also attached to the lower surface of the expected plate portion 64e. This cushion material 70 prevents the expected plate portion 64e from coming into contact with the flat surface 72 of the lower frame 12b (resin lower frame 19b) and damaging the flat surface 72, and can also suppress the generation of abnormal noises and the like.

[0043] The long hole 66 is formed in the frame side plate portion 64a and extends along the X direction. The long hole 66 is a special-shaped hole called, for example, a daruma hole. The long hole 66 is a punched-out hole with a closed perimeter. The long hole 66 has a large-diameter portion 66a formed at one end in the extending direction (X direction), and a long small-diameter portion 66b extending from the large-diameter portion 66a toward the other end. The large-diameter portion 66a is formed in a circular shape, and its diameter is larger than the width in the short-side direction (Z direction) of the small-diameter portion 66b.

[0044] The elongated hole 66 is capable of inserting a frame-side fastener 74 that protrudes upward from the prospective surface 34 of the lower frame 12b in its axial direction (Y direction). The elongated hole 66 is capable of relatively moving the inserted frame-side fastener 74 in its extending direction (X direction) and locking it in the prospective direction (Z direction). The frame-side fastener 74 is, for example, a stepped screw having a flange portion 74a at its tip. The flange portion 74a has a larger diameter than the shaft portion 74b on the proximal end side. The large-diameter portion 66a has an inner diameter capable of inserting and removing the flange portion 74a. The small-diameter portion 66b has a prospective width such that the flange portion 74a cannot be inserted and removed, and the shaft portion 74b can be inserted. Thereby, the small-diameter portion 66b can prevent the flange portion 74a of the frame-side fastener 74 through which the shaft portion 74b is inserted from coming off in the Y direction.

[0045] The slit portion 67 is formed in the shoji side plate portion 64c and partially extends to the standing plate portion 64b. The slit portion 67 has a first slit 67a and a second slit 67b, and forms a substantially L shape in plan view. The first slit 67a is a notch extending in the prospective direction and opens in the standing plate portion 64b. That is, the first slit 67a is a shape in which a notch formed in the standing plate portion 64b is extended in the prospective direction to the shoji side plate portion 64c. A wide portion 67c is formed in the portion where the first slit 67a opens in the standing plate portion 64b. The width in the X direction of the wide portion 67c is a width capable of inserting and removing the flange portion 75a of the shoji-side fastener 75 described later, and is, for example, the same as the diameter of the large-diameter portion 66a of the elongated hole 66. The second slit 67b is a notch that bends and continues from the indoor-side end of the first slit 67a and extends in the X direction. The first slit 67a and the second slit 67b other than the wide portion 67c have, for example, the same width as the small-diameter portion 66b of the elongated hole 66.

[0046] The slit portion 67 can insert the shoji side fastener 75 protruding downward from the prospective surface 58 of the lower frame 47b in the prospective direction, and can move relatively along the extending direction of the slits 67a and 67b. The second slit 67b can lock the inserted shoji side fastener 75 in the Z direction. The shoji side fastener 75 may have the same or similar configuration except that its axial length is slightly longer than that of the frame side fastener 74. That is, the shoji side fastener 75 has a large-diameter flange portion 75a formed at the tip, and the shaft portion 75b has a smaller diameter than the flange portion 75a. The flange portion 75a can be inserted and removed in the prospective direction with respect to the wide portion 67c. The first slit 67a and the second slit 67b other than the wide portion 67c can prevent the flange portion 75a of the shoji side fastener 75 through which the shaft portion 75b is inserted from coming off in the Y direction.

[0047] As shown in FIGS. 7A and 7B, in the shoji fixing tool 64, the small-diameter portion 66b of the long hole 66 and the second slit 67b of the slit portion 67 overlap in the Y direction. The end portion of the small-diameter portion 66b (the end portion opposite to the large-diameter portion 66a side) is at a position substantially coinciding with the outer peripheral edge portion of the bent portion between the first slit 67a and the second slit 67b in the Y direction. The end portion of the second slit 67b (the end portion opposite to the first slit 67a side) is at a position overlapping the small-diameter portion 66b in the Y direction and does not overlap the large-diameter portion 66a.

[0048] As shown in FIGS. 4 and 6A, when the shoji 14 is in the fully closed position shown in FIG. 4, the axial directions of the frame side fastener 74 and the shoji side fastener 75 are coaxially arranged in the Y direction. That is, the X-direction positions of the frame side fastener 74 and the shoji side fastener 75 coincide with each other.

[0049] Next, a method for fixing the shoji 14 using the shoji fixing tool 64 will be described with reference to FIGS. 8A to 9B. In FIGS. 9A and 9B, the resin lower frame 19b is not shown.

[0050] The fitting 10 attaches the shoji fixing tool 64 after connecting the frame 47 of the shoji 14 to the frame body 12 with the hinge 60 at a factory or the like.

[0051] First, as shown in FIGS. 8A and 9A, the shoji fixing tool 64 inserts the frame-side fastener 74 protruding from the prospective surface 34 of the lower frame 12b into the large-diameter portion 66a of the long hole 66 and sets it at the position where the shaft portion 74b is inserted into the long hole 66. At this time, the shoji 14 is opened to the outside to some extent via the hinge 60. The large-diameter portion 66a has a diameter that allows the flange portion 74a of the frame-side fastener 74 to be inserted and removed. Therefore, the long hole 66 allows the frame-side fastener 74 to be inserted smoothly.

[0052] As shown in FIG. 8B, slide the shoji fixing tool 64 along the longitudinal direction (X direction) of the prospective surface 34. The sliding can be easily performed by operating the operation portion 65 with a fingertip or the like. Then, the frame-side fastener 74 relatively moves in the extending direction of the small-diameter portion 66b with the shaft portion 74b. The shoji fixing tool 64 is slid until the frame-side fastener 74 abuts against the end portion of the small-diameter portion 66b (the end portion opposite to the large-diameter portion 66a side).

[0053] Next, support the shoji 14 with the shoji fixing tool 64. As shown in FIGS. 8C and 9B, rotate the shoji 14, which was opened to the outside, in the closing direction. Then, the shoji-side fastener 75 protruding from the prospective surface 58 of the shoji 14 is inserted into the slit portion 67. That is, the shoji-side fastener 75 passes through the wide portion 67c, which is the entrance of the slit portion 67, with the flange portion 75a and the shaft portion 75b. The shoji 14 is closed until the finding surface 69 on the indoor side abuts against the finding plate portion 64d (cushion material 70). Then, the shoji-side fastener 75 moves to the position where the shaft portion 75b abuts against the indoor-side end portion of the first slit 67a (see FIG. 8D).

[0054] As shown in FIG. 8E, the shoji fixture 64 is slid along the longitudinal direction (X direction) of the end face 34. This sliding can also be easily performed by operating the operation portion 65 with a fingertip or the like. Then, the shaft portion 75b of the shoji side fastener 75 relatively moves in the extending direction of the second slit 67b. The shoji fixture 64 is slid until the shoji side fastener 75 abuts against the end portion (the end portion opposite to the first slit 67a side) of the second slit 67b. At this time, the frame side fastener 74 relatively moves such that the shaft portion 74b moves from the small diameter portion 66b of the long hole 66 toward the large diameter portion 66a. When the shoji side fastener 75 abuts against the end portion of the second slit 67b, the frame side fastener 74 is disposed in the middle of the small diameter portion 66b.

[0055] In this state, as shown in FIGS. 6A, 6B, and 8E, the frame side fastener 74 engages with the small diameter portion 66b to restrict relative movement in the end face direction, and the shoji side fastener 75 engages with the second slit 67b to restrict relative movement in the end face direction. Therefore, rotation of the shoji 14 in the end face direction is restricted, and the shoji 14 is fixed to the frame body 12 by the shoji fixture 64.

[0056] The fitting 10 is transported to the construction site in a state where the shoji 14 is fixed to the frame body 12 by the shoji fixture 64 and is attached to the building structure.

[0057] As an example of the construction procedure of the fitting 10, the shoji 14 is attached to the building structure while being fixed by the shoji fixture 64. That is, the frame body 12 is fixed to the building structure using the anchor attachment portions 20, 30, 38, the screws 23, and the like.

[0058] Next, attach the facing material 46. As shown in FIG. 4, for the shoji fixture 64, the operation portion 65 (prospective plate portion 64e) located at the uppermost part thereof is below the installation surface 71 (lower end surface 46c) of the facing material 46. For this reason, the facing material 46 can be easily assembled inward from the indoor side to the inside of the frame body 47 fixed to the frame body 12 by the shoji fixture 64. That is, the lower end surface 46c of the facing material 46 does not interfere with the prospective plate portion 64e. Subsequently, attach the pressing edge 48 to the frame body 47 to support the indoor side surface of the facing material 46. Thereby, the attachment of the facing material 46 is completed. The shoji fixture 64 may be left attached during the curing period until the shoji opening / closing device 61 and the stay damper 62 are attached, and removed when the shoji opening / closing device 61 and the stay damper 62 are attached.

[0059] As a procedure for removing the shoji fixture 64, operate the operation portion 65 on the prospective surface (flat surface 72) of the lower frame 12b with a fingertip or the like, and move the shoji fixture 64 at the position shown in FIG. 8E to the position shown in FIG. 8D. Thereby, the shoji side fastener 75 is disposed in the first slit 67a. Then, open the shoji 14 to the outdoor side to disengage the shoji side fastener 75 from the shoji fixture 64. Subsequently, while keeping the shoji 14 open to a certain extent, operate the operation portion 65 again, and move the shoji fixture 64 at the position shown in FIG. 8C to the position shown in FIG. 8A. Thereby, the frame side fastener 74 is disposed in the large diameter portion 66a of the long hole 66. Then, the shoji fixture 64 can be easily removed from the frame side fastener 74 by simply gripping it with a fingertip or the like from the indoor side of the fitting 10 and pulling it upward.

[0060] As described above, the fitting 10 of the present embodiment includes a shutter fixture 64 that fixes the shutter 14 rotatably supported with respect to the frame body 12 to the closed position. The shutter fixture 64 has an elongated hole 66 and a slit portion 67. The elongated hole 66 is a hole portion with a closed periphery. The elongated hole 66 extends along the longitudinal direction of the prospective surface 34 of the frame body 12, and the frame side fastener 74 can be inserted along its axial direction, and relative movement of the inserted frame side fastener 74 in the prospective direction can be restricted. The slit portion 67 has a first slit 67a into which the shutter side fastener 75 can be inserted along the prospective direction, and a second slit 67b that bends from the first slit 67a and extends along the longitudinal direction of the prospective surface 34, and can restrict relative movement of the inserted shutter side fastener 75 in the prospective direction.

[0061] Therefore, the shutter fixture 64 can lock the frame side fastener 74 protruding from the prospective surface 34 of the frame body 12 with the elongated hole 66 having a closed periphery. For this reason, even when the fitting 10 is a high-weight and large-sized window or the like, for example, the shutter fixture 64 can receive the wind pressure received by the shutter 14 with the high-strength elongated hole 66. For this reason, the shutter fixture 64 can stably fix the shutter 14.

[0062] Specifically, for example, consider the case where the shutter 14 in the closed position shown in FIG. 4 receives an external force to rotate to the outdoor side. In this case, the load from the shutter 14 is transmitted from the shutter side fastener 75 to the shutter fixture 64, and the shutter fixture 64 receives the load in the direction of moving to the outdoor side. Then, the shutter fixture 64 is strongly pressed against the inner wall surface on the indoor side of the elongated hole 66 by the frame side fastener 74 fixed to the frame body 12. However, the elongated hole 66 is a through hole with a closed entire circumference. For this reason, deformation of the peripheral edge portion (frame side plate portion 64a) of the elongated hole 66 due to the load from the frame side fastener 74 is suppressed, and the shutter 14 can be stably supported. is possible.

[0063] The elongated hole 66 of this embodiment is a Daruma hole (irregular hole) having a large-diameter portion 66a and a small-diameter portion 66b. Therefore, the large-diameter portion 66a can smoothly insert and remove the large-diameter flange portion 74a of the frame-side fastener 74, and the small-diameter portion 66b can stably lock the shaft portion 74b of the frame-side fastener 74. The frame-side fastener 74 may have a cylindrical structure with only the shaft portion 74b without the flange portion 74a. In this case, the large-diameter portion 66a of the elongated hole 66 may be omitted. However, when the frame-side fastener 74 has the flange portion 74a and the elongated hole 66 is a Daruma hole having the large-diameter portion 66a, the frame-side fastener 74 is prevented from coming off from the small-diameter portion 66b, so that the stability of fixing the shoji 14 by the shoji fixture 64 is improved. The elongated hole 66 may be formed with the same diameter up to the small-diameter portion 66b as the large-diameter portion 66a. In this case, the shaft portion 74b locked by the elongated hole 66 will have some looseness, but the opening and closing of the shoji 14 can be prevented.

[0064] In the fitting 10, the shoji 14 has an inner pressing edge structure that holds the indoor-side surface of the facing material 46 with the pressing edge 48. Here, the operation portion 65 of the shoji fixture 64 has a prospective plate portion 64e bent from the finding plate portion 64d toward the indoor side. The prospective plate portion 64e is disposed outside the frame relative to the installation surface 71 of the facing material 46. Since the fitting 10 has the inner pressing edge structure in this way, the facing material 46 can be attached from the indoor side, and the construction work is easy even on high floors where there is no scaffold or the like outdoors. Moreover, the operation portion 65 of the shoji fixture 64 is disposed outside the frame relative to the installation surface 71 of the facing material 46. Therefore, when the fitting 10 attaches the facing material 46 from the indoor side, the operation portion 65 of the shoji fixture 64 does not interfere with the facing material 46. For this reason, the fitting 10 can perform the assembly work of the facing material 46 in a state where the shoji 14 is fixed by the shoji fixture 64, and the workability is further improved. It is also possible to prevent the frame body 47 from accidentally opening during the assembly work of the facing material 46. Further, the prospective plate portion 64e of the operation portion 65 is bent from the finding plate portion 64d toward the indoor side. Therefore, the operation portion 65 has high operability from the indoor side, and the prospective plate portion 64e does not interfere with the facing material 46 installed on the installation surface 71.

[0065] The shoji fixture according to one aspect of the present invention is a shoji fixture that fixes a shoji supported rotatably with respect to a frame body to a closed position. The frame body has a frame-side fastener protruding from an expected surface, and the shoji has a shoji-side fastener protruding from an expected surface facing the expected surface of the frame body. The shoji fixture includes a long hole that extends along the longitudinal direction of the expected surface of the frame body, into which the frame-side fastener can be inserted along its axial direction, and whose periphery is closed and can restrict relative movement of the inserted frame-side fastener in the expected direction, a first slit into which the shoji-side fastener can be inserted along the expected direction, and a slit portion having a second slit that bends from the first slit and extends along the longitudinal direction and can restrict relative movement of the inserted shoji-side fastener in the expected direction. According to such a configuration, the frame-side fastener protruding from the expected surface of the frame body can be locked with the long hole whose periphery is closed. Therefore, even when the shoji fixture receives a high-load from the shoji, deformation of the periphery of the long hole is suppressed, and the shoji can be stably fixed.

[0066] The shoji has an inner pressing edge structure that holds the indoor-side surface of the surface material with a pressing edge, and includes an operation portion for relatively moving the shoji fixture with respect to the frame body and the shoji in the longitudinal direction. The operation portion has a finding plate portion that extends inward of the frame body between the finding surfaces of the frame body and the shoji facing each other, and a prospective plate portion that is bent from the finding plate portion toward the indoor side. When based on the inside-outside direction of the frame of the frame body, the prospective plate portion may be arranged outside the frame than the installation surface of the surface material. Then, when attaching the surface material from the indoor side, interference of the operation portion with the surface material can be avoided, and the workability of the assembly work is improved.

[0067] The frame body may have a flat surface on the indoor side of the shoji, and the prospective plate portion may be arranged along the flat surface. Then, the operation portion can be further suppressed from protruding inside the frame, and the sliding operation of the operation portion becomes smoother.

[0068] The frame-side fastener has a large-diameter flange portion at the tip in the protruding direction from the expected surface of the frame body. The long hole is provided at one end in its extending direction and has a large-diameter portion through which the flange portion can be inserted, and a small-diameter portion that extends from the large-diameter portion toward the other end in the extending direction and can prevent the flange portion from coming off. Such a configuration may be adopted. In this way, the frame-side fastener having a flange portion can be smoothly inserted into and removed from the long hole, and the frame-side fastener can be prevented from coming off when the shoji is fixed, so that the fixing stability of the shoji is improved.

[0069] The fitting according to the second aspect of the present invention is a fitting provided with the shoji fixing tool of the above aspect, and includes the frame body and the shoji, and the frame body and the shoji are fixed by the shoji fixing tool. According to such a configuration, the shoji can be stably fixed to the frame body.

[0070] The frame body has an upper frame, a lower frame, and left and right vertical frames. The shoji has an upper frame, a lower frame, and left and right vertical frames. The shoji can be opened and closed toward the outdoor side with respect to the frame body by the upper frame being rotatably connected to the upper frame. The shoji fixing tool may be configured to fix the lower frame and the lower frame. In this way, the lower part of the shoji whose upper part is rotatably supported with respect to the frame body can be surely fixed to the frame body, and the fixing stability of the shoji is improved.

[0071] Note that 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.
