Summary of the Invention

Problem to be Solved by the Invention

[0004] By the way, Patent Document 1 does not describe a specific attachment structure of the crescent receptacle to the outer meeting stile, but generally, the crescent receptacle is screwed to the outer meeting stile. Considering this point, in Patent Document 1, it is considered that the crescent receptacle is attached to the outer meeting stile by passing the screw through a long hole (screw insertion portion, see FIG. 3 of Patent Document 1 etc.) formed extending in the left-right direction in the plate-like body of the crescent receptacle and tightening the screw into the outer meeting stile side (see FIG. 7 of Patent Document 1). However, when the crescent receptacle is attached to the outer meeting stile as described above, when tightening the screw, there is a risk that the crescent receptacle is displaced in the rotation direction by the rotation of the screw. Further, when the outer meeting stile is made of resin, rattling of the crescent receptacle tends to be larger than when the outer meeting stile is made of metal, and there is a higher risk that the crescent receptacle is displaced.

[0005] The present invention aims to provide a door fitting that can suppress misalignment of the crescent lock receiver attached to the outer meeting stile. [Means for solving the problem]

[0006] The present invention relates to a joinery comprising a frame and a sliding screen disposed within the frame, wherein the sliding screen has a frame and a facing material, the frame has at least an outer meeting frame to which the base of a crescent receiver of a crescent lock is attached by a screw, a cover material is attached to the outer meeting frame to cover the base from the interior side, the crescent receiver has a screw insertion portion through which the shaft of the screw is inserted and which extends in a direction that allows the position of the crescent receiver to be adjusted in the sliding direction of the sliding screen, and the cover material has an opening in which the head of the screw is placed and a rotation restricting portion that restricts the rotation of the crescent receiver around the screw. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a door or window fitting that can suppress misalignment of the crescent lock receiver attached to the outer meeting stile. [Brief explanation of the drawing]

[0009] [Structure of this embodiment] Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 and 2, the sliding window 1 as a building fixture according to this embodiment is a so-called resin window installed in an opening in the building structure, and comprises a resin window frame 2 (frame body) and an outer sash 3 (sash) and an inner sash 4 (sash) that are slidably arranged within the window frame 2. This sliding window 1 can be installed, for example, as a standalone unit in an opening in the building structure, or as an inner window installed on the interior side of an existing window. In the following explanation, for the sake of clarity, the left-right direction of sliding window 1 will be defined as the X-axis direction (the sliding direction of sashes 3 and 4), the up-down direction of sliding window 1 will be defined as the Y-axis direction, and the depth direction of sliding window 1 will be defined as the Z-axis direction. The X, Y, and Z axes are mutually orthogonal.

[0010] The outer sliding door 3 and the inner sliding door 4 have resin frame bodies 30, 40 and facing materials 10, 10. The frame bodies 30 and 40 include upper frames 31 and 41, lower frames 32 and 42, door-edge frames 33 and 43, and meeting frames 34 and 44. Meeting frame 34 constitutes the exterior meeting frame on the outside, and meeting frame 44 constitutes the interior meeting frame on the inside. The facing materials 10, 10 are composed of single-layer or double-layer glass panels, and in the case of double-layer glass, they may be composed of vacuum glass with a vacuum between the glass panels. The upper frame 31, lower frame 32, door edge frame 33, outer meeting frame 34, and facing material 10 are assembled to form the outer shoji screen 3. The upper frame 41, lower frame 42, door edge frame 43, inner meeting frame 44, and facing material 10 are assembled to form the inner shoji screen 4. The outer meeting stile 34, as shown in Figures 2 and 3, for example, comprises a resin stile body 340 having a hollow section 340A along the Y-axis direction, and a metal reinforcing member 51 positioned in the hollow section 340A. The reinforcing member 51 is formed in a hollow rectangular shape in plan view. In this embodiment, the reinforcing member 51 is not directly connected to the stile body 340. The frame body 340 has an exterior facing portion 341 and an interior facing portion 342 that are aligned in the X-axis direction, and an inner perimeter facing portion 343 and an outer perimeter facing portion 344 that are continuous with the exterior facing portion 341 and the interior facing portion 342 and aligned in the Z-axis direction, respectively. The hollow portion 340A is formed in a rectangular shape in plan view by the exterior facing portion 341, the interior facing portion 342, the inner perimeter facing portion 343 and the outer perimeter facing portion 344. The exterior facing portion 341 and the interior facing portion 342 extend inward towards the outer perimeter of the outer sash 3 in the X-axis direction compared to the inner perimeter facing portion 343. The exterior facing portion 341, the interior facing portion 342 and the inner perimeter facing portion 343 constitute a surface material holding groove 345 that holds the edge of the surface material 10 on the meeting side (door tail side). The interior surface of the interior facing piece 342 is formed flat along the X,Y axis direction (in-plane direction). The crescent receiver 71 of the crescent lock 60, described later, is attached to the exterior meeting stile 34 along the interior surface of the interior facing piece 342, and the cover material 81, described later, is also attached. For these attachments, the interior facing piece 342 has a hole through which the shaft portion 13 of the screw 11, described later, is inserted, rectangular arrangement holes 15, 15 where the protruding portions 78, 78, described later, are placed, and square-shaped holes 16, 16 (square holes) through which the engaging projections 83, 83, described later, are inserted. The reinforcing material 51 has a screw hole into which the shaft portion 13 is screwed, and holes 52, 52 through which the engaging projections 83, 83 are inserted. The placement holes 15, 15 are arranged in the Y-axis direction with screw holes in between, the hole portions 16, 16 are arranged in the Y-axis direction with the placement holes 15, 15 in between, and the hole portions 52, 52 are positioned to communicate with the hole portions 16, 16 in the Z-axis direction. The hole portions 16, 16, 52, 52 constitute the insertion holes 34A, 34A of the outer meeting frame 34 into which the engaging projections 83, 83 are inserted. The inner meeting stile 44 is constructed in substantially the same manner as the outer meeting stile 34 described above, and holds the meeting edge of the facing material 10 in the inner sliding door 4. The crescent 61 of the crescent lock 60, which will be described later, is attached to the outer peripheral projection piece 444 of the inner meeting stile 44.

[0011] The aforementioned outer meeting stile 34 and inner meeting stile 44 are provided with crescent locks 60. The crescent lock 60 comprises a crescent 61 and a metal crescent receiver 71 that receives the crescent 61.

[0012] The crescent 61 comprises a base 62 attached to the outer peripheral projection piece 444 of the inner meeting stile 44, and a crescent body 63 that is rotatably connected to the base 62 about an axis along the X-axis. The crescent body 63 has a handle 64 for rotating the crescent 61, and a semicircular hook portion 65 that engages with and disengages from the crescent receiver 71 by the rotation of the handle 64.

[0013] As shown in Figures 3 to 5, for example, the crescent receiver 71 has a plate-shaped body 74 having upper and lower side edges 72, 72 along the X-axis direction, a receiver portion 75 formed on one end of the plate-shaped body 74 in the X-axis direction and to which the aforementioned hook portion 65 engages and disengages, a pair of upper and lower screw insertion portions 77, 77 formed on the base portion 76 which is the other end of the plate-shaped body 74 in the X-axis direction and consisting of elongated holes extending in the X-axis direction, and a pair of protruding portions 78, 78 that protrude toward the outer meeting frame 34 in the Z-axis direction and press against the reinforcing member 51. In this embodiment, the screw insertion portions 77, 77 are composed of elongated holes extending in the X-axis direction, so as to extend in a direction that allows the crescent receiver 71 to be positioned in the X-axis direction. The shaft portion 13 of a screw 11, which has a head portion 12 and a shaft portion 13, is inserted through these screw insertion portions 77, 77. When the screw 11 is tightened, the shaft portion 13 is inserted through the frame body 340 and screwed into the reinforcing member 51, and the head portion 12 engages with the crescent receiver 71, thereby fixing the crescent receiver 71 to the outer meeting frame 34. The protruding portions 78, 78 are arranged with the screw insertion portions 77, 77 interposed therebetween in the Y-axis direction. By being arranged at two such positions, the bending force that can be applied to the crescent receptacle 71 when tightening the screw 11 can be dispersed compared to, for example, a case where the protruding portions are arranged at only one position.

[0014] A base portion 76 of the crescent receptacle 71 is covered from the indoor side by a cover member 81. The cover member 81 has openings 82, 82 in which the head portions 12 of the screws 11 are disposed, and a pair of upper and lower engaging convex portions 83, 83 arranged with the openings 82, 82 interposed therebetween in the Y-axis direction. The engaging convex portions 83, 83 extend toward the outer meeting stile 34 in the Z-axis direction. As shown in FIG. 5, the upper engaging convex portion 83 includes a U-shaped insertion piece portion 831 that opens upward, and an elastically deformable engaging piece portion 832 disposed at an upper position relative to the insertion piece portion 831, and a claw portion 84A is formed upward at a tip end of the engaging piece portion 832. Further, the lower engaging convex portion 83 includes a U-shaped insertion piece portion 831 that opens downward, and an elastically deformable engaging piece portion 832 disposed at a lower position relative to the insertion piece portion 831, and a claw portion 84B is formed downward at a tip end of the engaging piece portion 832. Further, the cover member 81 has a rotation restricting portion 85 that restricts rotation of the crescent receptacle 71 around the screw 11. The rotation restricting portion 85 is formed on the back surface 81A of the cover member 81 facing the crescent receptacle 71 in the Z-axis direction, and is constituted by a bottom surface 86 extending along the X-axis direction, and restricting surfaces 87, 87 which are a pair of side surfaces continuous with the bottom surface 86 and extending along the X-axis direction. A base portion 76 of the crescent receptacle 71 is disposed in this rotation restricting portion 85, the bottom surface 86 is disposed facing the indoor surface of the crescent receptacle 71, and the restricting surfaces 87, 87 are disposed opposite and parallel to the upper and lower side edges 72, 72 along the X-axis direction of the crescent receptacle 71. The spacing dimension in the Y-axis direction between the restricting surfaces 87, 87 is set to be equivalent to the width dimension of the crescent receptacle 71 in the Y-axis direction. Note that the spacing dimension in the Y-axis direction between the restricting surfaces 87, 87 may be set to be slightly larger than the width dimension of the crescent receptacle 71 in the Y-axis direction; in this case, the dimension is set such that a gap that may occur between the restricting surfaces 87, 87 and the side edges 72, 72 of the crescent receptacle 71 is as small as possible.

[0015] [Procedure for Mounting Crescent Receptacle] The aforementioned crescent receptacle 71 is mounted in the following manner. First, the outdoor surface of the crescent receptacle 71 is disposed along the indoor facing surface of the indoor facing piece portion 342 of the stile main body 340, the protruding portions 78, 78 are disposed in the disposition holes 15, 15, and subsequently, the shaft portion 13 of the screw 11 is inserted into the screw insertion portions 77, 77 of the crescent receptacle 71 and screwed into the screw hole of the reinforcing member 51. At this time, the screw 11 is loosely tightened to temporarily fix the crescent receptacle 71. Next, the cover member 81 is attached to the outer meeting stile 34. Specifically, the engaging convex portions 83, 83 are inserted into the insertion hole portions 34A, 34A, and the claw portions 84A, 84B are engaged with the reinforcing member 51. When inserting the engaging convex portions 83, 83 into the insertion hole portions 34A, 34A, the engaging piece portions 832, 832 are temporarily elastically deformed as the claw portions 84A, 84B abut against the reinforcing member 51 at the hole portions 52, 52. At this time, the base portion 76 of the crescent receptacle 71 is disposed in the rotation restricting portion 85, and the restricting surfaces 87, 87 are disposed opposite to the side edges 72, 72 of the crescent receptacle 71 in the Y-axis direction. The head portion 12 of the screw 11 is disposed in the openings 82, 82. Next, the crescent receiver 71 is positioned in the X-axis direction, and then the screws 11 are tightened to press the protruding parts 78, 78 against the interior surface of the reinforcing material 51, thereby permanently fixing the crescent receiver 71 in place. At this time, when the crescent receiver 71 is attached to the reinforcing material 51, which is not directly connected to the frame body 340, by tightening the screws 11, the crescent receiver 71 will try to rotate slightly. However, since the rotation of the crescent receiver 71 is restricted by the rotation restricting part 85 of the cover material 81, displacement of the crescent receiver 71 is suppressed. In this fixed state, as shown in Figure 6, the engaging projection 83 is inserted into the insertion hole 34A, the protruding portion 78 is positioned in the placement hole 15 and pressed against the interior surface of the reinforcing member 51, and the screw 11 is inserted through the screw insertion portion 77 and screwed into the screw hole of the reinforcing member 51. Note that Figure 6(A) is a cross-sectional view taken along the line AA shown in Figure 3(A), Figure 6(B) is a cross-sectional view taken along the line BB shown in Figure 3(A), and Figure 6(C) is a cross-sectional view taken along the line CC shown in Figure 3(A). In this embodiment, the mounting structure 5 for the crescent lock receiver is constructed by attaching the crescent lock receiver 71 in this manner.

[0016] In the sliding window 1 of this embodiment, rotational force is applied to the crescent receiver 71 when the screw 11 is tightened, but the rotation of the crescent receiver 71 is restricted by the side edges 72, 72 of the crescent receiver 71 contacting the restricting surfaces 87, 87 of the rotation restricting portion 85 of the cover material 81, thereby suppressing displacement of the crescent receiver 71 in the rotational direction. Furthermore, even if an external force in the X-axis direction is applied to the crescent receiver 71, the protruding portions 78, 78 of the metal crescent receiver 71 are pressed against the reinforcing material 51, so displacement of the crescent receiver 71 in the X-axis direction can be suppressed. Note that when the screw 11 is loosened, the position of the crescent receiver 71 can be adjusted in the X-axis direction. Furthermore, in the mounting structure 5 for the crescent receiver in the sliding window 1, the protruding parts 78, 78 abut against the reinforcing material 51, thereby preventing excessive force from being applied to the interior facing piece 342 of the resin frame body 340 when the screws 11 are tightened, which would cause creep deformation of the interior facing piece 342 and reduce the mounting strength of the crescent receiver 71.

[0017] [Differentiation] In the above embodiment, a sliding window 1 having one outer sash 3 and one inner sash 4 was described as a joinery, but the window is not limited to this, and a window having multiple outer sashes 3 and inner sashes 4 within a window frame 2 may also be described as a joinery. For example, as shown in Figure 7, a sliding window 1B with four sashes may be used as the joinery. In this case, the sliding window 1B has a pair of sliding window sections 90 in the X-axis direction, each consisting of an outer sash 3 and an inner sash 4. The pair of sliding window sections 90 are arranged to slide open within a common window frame 2B, and the inner sashes 4 are abutted against each other. In this case, the door frames 43 of adjacent inner sashes 4 are configured as abutting frames that abut against each other. The crescent lock 60 is located at the meeting portion of each sliding window section 90, on the door frame side of each outer sash 3 of the sliding window section 90. Therefore, for example, when one inner sash 4 is moved to close in the X-axis direction, if that inner sash 4 collides with the other inner sash 4, an external force due to the closing movement is applied to the crescent receiver 71 of the crescent lock 60, and there is a risk that the crescent receiver 71 will be displaced in the X-axis direction due to this external force. However, since the protruding parts 78, 78 are pressed against the reinforcing material 51, this displacement is suppressed. In the modified example shown in Figure 7, the inner sliding doors 4 are butted against each other, but instead, the outer sliding doors 3 may be butted against each other. Alternatively, the fixture may be configured to include five or more sliding shoji screens.

[0018] In the above embodiment, the rotation restricting portion 85 has restricting surfaces 87, 87 parallel to the side edges 72, 72 extending in the X-axis direction of the crescent receiver 71. However, it is not limited to this, and even if the side edges 72, 72 have other shapes, the restricting surfaces 87, 87 may be formed in a shape complementary to that shape, or the restricting surfaces 87, 87 may be configured to partially contact the side edges 72, 72 in the Y-axis direction. In the above embodiment, the crescent receiver 71 is screwed to the reinforcing member 51 of the outer meeting stile 34, but if there is no reinforcing member 51, it may be screwed to the frame body 340. Also, if there is no reinforcing member 51, the cover material 81 may be attached to the frame body 340. In the above embodiment, the crescent receiver 71 has protruding portions 78, 78, but it is not limited to this, and for example, if it is sufficient to suppress the displacement of the crescent receiver 71 when the screw 11 is tightened, the configuration of the protruding portions 78, 78 may be omitted. In this case, the configuration of the mounting holes 15, 15 may also be omitted. In the above embodiment, the crescent receiver 71 is provided with protruding portions 78, 78, but instead, for example, a protruding portion that presses against the crescent receiver 71 may be provided on the reinforcing member 51. In this case, for example, two U-shaped reinforcing materials may be combined to form a hollow rectangular reinforcing member 51, and by sequentially inserting the reinforcing materials into the frame body 340, the reinforcing member 51 can be easily inserted into the frame body 340 even if there is a protruding portion. In the above embodiment, for example, the frame body 340 is configured to have a flat interior-facing surface. However, for example, the frame body 340 may be provided with a folded portion along the Y-axis direction that protrudes inward from the interior-facing surface. In this case, by cutting out a part of the folded portion, a configuration can be made in which the crescent lock receiver 71 can be placed. A cover material 81 may be fitted into the folded portion. In the above embodiment, the outer meeting stile 34 is configured as a so-called resin stile, having a resin stile body 340. However, it is not limited to this, and may be configured as a composite stile having, for example, a metal stile material such as aluminum and a resin stile material. In this case, the configuration of the reinforcing member 51 may be omitted, and the crescent receiver 71 and cover material 81 may be attached to the metal stile material. In this case, the engaging protrusions 83, 83 may be configured to engage with the metal stile material. In the above embodiment, the outer meeting stile 34 is configured such that the engaging projections 83, 83 engage with a reinforcing member 51 disposed in the hollow portion 340A of the resin stile body 340. However, the embodiment is not limited to this configuration, and for example, if there is no reinforcing member 51, the engaging projections 83, 83 may engage with the stile body 340. In the above embodiment, a sliding window 1 was described as a joinery, but other types of joinery such as a single-hung window or a double-hung window may also be used. When a double-hung window is equipped with a crescent lock 60 and used as joinery, the sliding direction of the sash is the Y-axis direction, and the orientation in which the crescent lock 60 is attached is also changed according to the sliding direction of the sash.

[0019] [Summary of the invention] (1) The joinery of the present invention comprises a frame and a sliding screen disposed within the frame, wherein the sliding screen has a frame and a facing material, the frame has at least an outer meeting frame to which the base of a crescent receiver of a crescent lock is attached by a screw, a cover material is attached to the outer meeting frame to cover the base from the interior side, the crescent receiver has a screw insertion portion through which the shaft of the screw is inserted and which extends in a direction that allows the position of the crescent receiver to be adjusted in the sliding direction of the sliding screen, and the cover material has an opening in which the head of the screw is disposed and a rotation restricting portion that restricts the rotation of the crescent receiver around the screw. According to the joinery of the present invention, the aforementioned crescent receiver, which is attached to the outer meeting stile by a screw, has its rotation restricted by a rotation-restricting portion of a cover material that covers its base from the interior side. This prevents the crescent receiver from shifting position in the direction of the screw's rotation when the screw is tightened. (2) In the joinery of the present invention, the crescent receiver may have a side edge along the sliding direction, and the rotation restricting portion may have a restricting surface that is opposite and parallel to the side edge. With this configuration, the position of the crescent receiver in the sliding direction can be adjusted even when the screw is loosened, and when the screw is tightened, the side edge of the crescent receiver can come into contact with the regulating surface, thereby restricting the rotation of the crescent receiver and suppressing misalignment of the crescent receiver. (3) In the joinery of the present invention, the cover material may have an engaging projection that protrudes toward the outer meeting stile and engages with the outer meeting stile, and the outer meeting stile may have an insertion hole into which the engaging projection is inserted. With this configuration, the cover material can be easily and securely attached to the outer meeting frame by inserting the engaging protrusion of the cover material into the insertion hole and engaging it with the outer meeting frame. (4) In the joinery of the present invention, the outer meeting stile has a resin stile body having a hollow portion and a metal reinforcing material disposed in the hollow portion, the insertion hole portion is composed of a hole formed in the stile body and a hole formed in the reinforcing material, and the engaging projection portion may be inserted through each of the holes and engaged with the reinforcing material. With this configuration, the engaging projection engages with a metal reinforcing material, which increases the engagement strength compared to, for example, engaging the engaging projection with a resin part. This allows the cover material to be attached to the outer frame more securely. Furthermore, when the frame body of the outer meeting stile is made of resin, there tends to be more play with the crescent lock receiver compared to when it is made of metal. However, as mentioned above, the rotation restricting part restricts the rotation of the crescent lock receiver, so the aforementioned misalignment can be effectively suppressed. (5) In the joinery of the present invention, the crescent receiver has a protruding portion that extends toward the outer meeting stile, the frame body has an arrangement hole in which the protruding portion is positioned, and the protruding portion may be pressed against the reinforcing material by tightening the screw. With this configuration, the protruding portion can be pressed against a metal reinforcing material, so that even if an external force in the sliding direction of the sliding screen is applied to the crescent receiver, for example, it is possible to suppress the crescent receiver from shifting position in that sliding direction. Furthermore, even when the screw is tightened, the protruding portion is pressed against the reinforcing material, which suppresses creep deformation of the resin frame body caused by excessive force being applied to the frame body, and thus suppresses the reduction in the mounting strength of the crescent receiver due to such creep deformation. (6) In the joinery of the present invention, the joinery has at least one pair of sliding window sections in the left-right direction, each of which has an outer sash and an inner sash as the sash, and the outer sash or the inner sash of each sliding window section is configured to abut each other, and the crescent lock may be provided at the meeting portion of each sliding window section. With this configuration, when one of the interior sliding doors of the door closes in the sliding direction, if that interior sliding door collides with the other interior sliding door, an external force due to the closing movement is applied to the crescent receiver of the crescent lock. This external force may cause the crescent receiver to shift position in the sliding direction. However, since the protruding part is pressed against the reinforcing material, this positional shift can be suppressed. [Explanation of Symbols]
