Mode for Carrying Out the Invention

[0010] [First Embodiment] Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the fitting 1 of this embodiment is a single-leaf door including a door frame 2 which is a fitting frame attached to an opening of a building, and a door 3 which is a shoji door attached to be openable and closable within the door frame 2. In the following description, the left-right direction of the fitting 1 is defined as the X-axis direction, the up-down direction of the fitting 1 is defined as the Y-axis direction, and the prospective direction of the fitting 1 is defined as the Z-axis direction. The X, Y, and Z-axis directions are orthogonal to each other.

[0011] As shown in FIG. 1, the door frame 2 is a square frame formed by joining an upper frame 21, a lower frame 22, a suspension-side vertical frame 23, and a leading-edge vertical frame 24 which is a leading-edge frame in a square frame shape. The upper frame 21, the lower frame 22, the suspension-side vertical frame 23, and the leading-edge vertical frame 24 are each composed of an aluminum extrusion profile. As shown in FIG. 2, the leading-edge vertical frame 24 includes a prospective surface portion 241 provided along the Z-axis direction (prospective direction), a door-contact portion 242 extending from the prospective surface portion 241 toward the suspension-side vertical frame 23, that is, in the X-axis direction, an outdoor surface portion 243 extending from the prospective surface portion 241 toward the suspension-side vertical frame 23, an indoor surface portion 244 extending from the prospective surface portion 241 toward the suspension-side vertical frame 23, and an attachment surface portion 245 connecting the outdoor surface portion 243 and the indoor surface portion 244. The outdoor surface portion 243 extends linearly from the prospective surface portion 241 in the finding direction of the leading-edge vertical frame 24, that is, in the X-axis direction. On the other hand, the indoor surface portion 244 extends from the prospective surface portion 241 in the X-axis direction, further extends to the outdoor side in the Z-axis direction, and further extends in the X-axis direction to be connected to the attachment surface portion 245, and is formed in a substantially Z-shaped cross section as a whole. The attachment surface portion 245 has a surface, that is, a surface facing the door 3, which is a surface along the Z-axis direction, that is, the prospective direction. A holding groove that opens to the outdoor side is formed in the door-contact portion 242, and a sealing material 26 that abuts against the door 3 to ensure airtightness is attached to the holding groove. A synthetic resin cover material 27 that covers the indoor exposed surface of the leading-edge vertical frame 24 is attached to the leading-edge vertical frame 24. In FIGS. 3 and 4, the illustration of the sealing material 26 and the cover material 27 is omitted. Since the suspension-side vertical frame 23 has the same configuration as the leading-edge vertical frame 24, the description thereof is omitted.

[0012] As shown in Fig. 1, the door 3 is composed of a frame body 30 formed by framing an upper frame 31, a lower frame 32, a hanging-side vertical frame 33, and a door-tip vertical frame 34, and a multilayer glass 35 which is a surface material incorporated inside the frame body 30. The frame body 30 is a so-called vertical-lap frame body in which the edges of the upper frame 31 and the lower frame 32 are fixed by abutting against the hanging-side vertical frame 33 and the door-tip vertical frame 34. As shown in Figs. 1 and 2, the hanging-side vertical frame 33 is attached to the hanging-side vertical frame 23 of the door frame 2 via a hinge 39. Thereby, the door 3 is attached to the door frame 2 so as to be openable and closable. Since the fitting 1 of the present embodiment is an outward-opening door, the door 3 which is a shoji screen is provided so as to open to the outdoor side and close to the indoor side. The hinge 39 is a flag hinge including a frame-side hinge 391 fixed to the hanging-side vertical frame 23 and a frame-side hinge 392 attached to the hanging-side vertical frame 33.

[0013] At the intermediate position in the vertical direction of the door-tip vertical frame 34, a lock case 40 which is a locking component and a lever handle 36 are attached. At the intermediate position in the vertical direction of the door-tip vertical frame 24, a lock receiving device 50 to which a latch bolt 41 and a dead bolt 42 which are lock bolts protruding from and retracting into the lock case 40 are engaged is attached.

[0014] As shown in Figs. 3 and 4, a frame opening 25 is formed in the attachment surface portion 245 of the door-tip vertical frame 24. As shown in Fig. 4, the frame opening 25 is a rectangular opening having a height dimension in the vertical direction (Y-axis direction) of H1 and a width dimension in the prospective direction (Z-axis direction) of W1. A lock receiving body 70 described later is arranged in this frame opening 25. In the attachment surface portion 245, long holes 28 which are first long holes are respectively formed above and below the frame opening 25. Each long hole 28 is a long hole extending in the vertical direction. Also, the formation position of the long hole 28 in the Z-axis direction is set at the central position in the width direction (Z-axis direction) of the frame opening 25. The width dimension of the long hole 28 is set according to the screw inserted into the long hole 28.

[0015] [Lock receiving device] As shown in FIGS. 2 and 3, the ingot receiver 50 includes a back plate 60, an ingot receiver body 70, and an ingot receiver cover 80.

[0016] [Back plate] As shown in FIG. 5, the back plate 60 is a rectangular metal plate, with a height dimension in the vertical direction of H11 and a width dimension in the prospective direction of W11. In this embodiment, the back plate 60 is made of steel. A rectangular opening 61 is formed in the middle of the back plate 60 in the vertical direction. The height dimension of the opening 61 is H12, and the width dimension is W12. Also, the thickness dimension of the back plate 60 is such that the force applied when the latch bolt 41 and the dead bolt 42 are engaged with the ingot receiver body 70 can be supported by the door end vertical frame 24 through the back plate 60, and for example, it is 1.6 mm. Two screw holes 62 and 63 are formed above and below the opening 61 of the back plate 60, respectively. The screw hole 62 is formed near the upper end and the lower end of the back plate 60, and is a screw hole used when attaching the back plate 60 to the attachment surface portion 245 of the door end vertical frame 24. The screw hole 63 is formed between the upper and lower screw holes 62 and the opening 61, and is a screw hole for attaching the ingot receiver body 70 and the ingot receiver cover 80. The back plate 60 is disposed on the back surface side of the attachment surface portion 245, that is, inside the hollow portion of the door end vertical frame 24. The screw hole 62 of the back plate 60 is provided at a position corresponding to the long hole 28 of the door end vertical frame 24. As shown in FIG. 3, by inserting a screw 91, which is a first fastening component, into the long hole 28, which is a first long hole, and screwing it into the screw hole 62, the back plate 60 is attached to the attachment surface portion 245. At this time, since the long hole 28 is long in the vertical direction, the height position of the back plate 60 can be adjusted by loosening the screw 91 and moving it within the long hole 28. For example, in this embodiment, the back plate 60 can be moved about 3 mm in the vertical direction. The position adjustment direction of the back plate 60 with respect to the door end vertical frame 24, that is, the vertical direction (Y-axis direction), which is the longitudinal direction of the door end vertical frame 24, is the first direction.

[0017] [Ingot receiver body] As shown in Fig. 6, the ingot receiver body 70 is a rectangular metal plate, with a height dimension in the vertical direction being H21 and a width dimension in the prospective direction being W21. In this embodiment, the ingot receiver body 70 is made of stainless steel. A rectangular opening 71 is formed in the middle of the ingot receiver body 70 in the vertical direction. The height dimension of the opening 71 is H22, and the width dimension is W22. Also, the thickness dimension of the ingot receiver body 70 is such that it has the rigidity to support the force applied when the latch bolt 41 and the dead bolt 42 are engaged with the opening 71, for example, it is 1.5 mm. Above and below the opening 71 of the ingot receiver body 70, elongated holes 73, which are second elongated holes, are respectively formed. Each elongated hole 73 is an elongated hole extending in the prospective direction (Z-axis direction). As shown in Fig. 3, the ingot receiver body 70 is attached to the back plate 60 with screws 92, which are second fastening components, screwed into the screw holes 63 of the back plate 60 through the elongated holes 73, which are second elongated holes. At this time, since the elongated holes 73 are long in the prospective direction, the position of the ingot receiver body 70 in the prospective direction can be adjusted by loosening the screws 92 and moving them within the elongated holes 73. For example, in this embodiment, the ingot receiver body 70 can move approximately 3 mm in the prospective direction with respect to the back plate 60. The position adjustment direction of the ingot receiver body 70 with respect to the back plate 60, that is, the prospective direction (Z-axis direction) is the second direction. The ingot receiver body 70 is attached to the surface of the back plate 60, that is, the surface on the ingot case 40 side, and is disposed within the frame opening 25 of the attachment surface portion 245. The thickness dimension of the ingot receiver body 70 is the same as the thickness dimension of the attachment surface portion 245, and the surface of the ingot receiver body 70 is flush with the surface of the attachment surface portion 245. The height dimension H21 and the width dimension W21 of the ingot receiver body 70 are set to be smaller than the height dimension H1 and the width dimension W1 of the frame opening 25 so that the position of the ingot receiver body 70 within the frame opening 25 can be adjusted in the vertical direction and the prospective direction. Specifically, the height dimension H21 is set such that when the back plate 60 is vertically adjusted with respect to the mounting surface portion 245, the ingot receiver main body 70 can move vertically together with the back plate 60. In the present embodiment, since the back plate 60 can be moved vertically by about 3 mm, the height dimension H21 is set to be 3 mm or more smaller than the height dimension H1, and in the present embodiment, H21 = H1 - 3 mm. The width dimension W21 of the ingot receiver main body 70 is set such that the ingot receiver main body 70 can be horizontally adjusted with respect to the back plate 60. In the present embodiment, since the ingot receiver main body 70 can be moved horizontally by about 3 mm with respect to the back plate 60, the width dimension W21 is set to be 3 mm or more smaller than the width dimension W1, and in the present embodiment, W21 = W1 - 3 mm.

[0018] [Ingot Receiver Cover] As shown in FIG. 7, the ingot receiver cover 80 is a rectangular metal plate, with the height dimension in the vertical direction being H31 and the width dimension in the prospective direction being W31. In the present embodiment, the ingot receiver cover 80 is made of stainless steel. A rectangular opening 81 is formed in the middle of the ingot receiver cover 80 in the vertical direction. The height dimension of the opening 81 is H32 and the width dimension is W32. The height dimension H31 and width dimension W31 of the ingot receiver cover 80 are made larger than the height dimension H1 and width dimension W1 of the frame opening 25. As shown in FIG. 3, the ingot receiver cover 80 is set to a size that can hide the frame opening 25. Further, the ingot receiver cover 80 is attached to the surface of the ingot receiver main body 70 and is arranged across the surfaces of the ingot receiver main body 70 and the mounting surface portion 245. That is, the ingot receiver cover 80 hides the back plate 60, the ingot receiver main body 70, and the frame opening 25. Also, the openings 71 and 81 overlap, and the latch bolt 41 and dead bolt 42 inserted into the openings 71 and 81 are mainly engaged with the opening 71, and the forces applied from the bolts 41 and 42 are supported by the ingot receiver main body 70, so there is no need for the ingot receiver cover 80 to support. For this reason, the thickness dimension of the ingot receiver cover 80 is set to, for example, 0.5 mm, etc., and the ingot receiver cover 80 is configured in a thin plate shape. As shown in FIG. 7, long holes 83 are formed above and below the opening 81 of the tablet receiver cover 80, respectively. Each long hole 83 is a long hole extending in the prospective direction (Z-axis direction). The tablet receiver cover 80 is attached to the back plate 60 together with the tablet receiver body 70 by screws 92 that are screwed into the screw holes 63 of the back plate 60 through the long holes 83. Since the long holes 83 are long in the prospective direction, the position of the tablet receiver cover 80 in the prospective direction can be adjusted by loosening the screws 92 and moving them within the long holes 83. For example, in this embodiment, the tablet receiver cover 80 can move approximately 3 mm in the prospective direction (the second direction) with respect to the back plate 60, similar to the tablet receiver body 70. Note that the long holes 83 have the same shape and size as the long holes 73, and are arranged so as to overlap each other when viewed from the front in the X-axis direction of the mounting surface portion 245.

[0019] The height dimension H32 of the opening 81 is the same as the height dimension H22 of the opening 71, and the width dimension W32 of the opening 81 is the same as the width dimension W22 of the opening 71. Therefore, the opening 71 of the tablet receiver body 70 and the opening 81 of the tablet receiver cover 80 have the same shape and size, and are arranged so as to overlap each other when viewed from the front in the X-axis direction of the mounting surface portion 245. Also, since the tablet receiver body 70 and the tablet receiver cover 80 move integrally with the back plate 60 in the vertical direction, the height dimensions H22 and H32 of the openings 71 and 81 are the same as the height dimension H12 of the opening 61. On the other hand, since the tablet receiver body 70 and the tablet receiver cover 80 move with respect to the back plate 60 in the prospective direction, the width dimension W12 of the opening 61 of the back plate 60 is made larger than the width dimensions W22 and W32 of the openings 71 and 81, so that when the tablet receiver body 70 and the tablet receiver cover 80 move in the prospective direction, the periphery of the opening 61 of the back plate 60 is set not to be exposed from the openings 71 and 81. In this embodiment, since the tablet receiver body 70 and the tablet receiver cover 80 move 3 mm in the prospective direction with respect to the back plate 60, the width dimension W12 of the opening 61 is made 3 mm larger than the width dimensions W22 and W32 of the openings 71 and 81.

[0020] [Position adjustment of the tablet receiver device] Next, the position adjustment of the lock receiver device 50 will be described with reference to FIG. 8. In the present embodiment, after the door 3 is attached to the door frame 2 via the hinge 39, the attachment position of the lock receiver device 50 can be adjusted in two directions, the vertical direction (Y-axis direction) and the depth direction (Z-axis direction). Thereby, the positions of the openings 71 and 81 of the lock receiver main body 70 and the lock receiver cover 80 can be adjusted according to the protruding and retracting positions of the latch bolt 41 and the dead bolt 42. To adjust the positions of the openings 71 and 81 in the vertical direction, the position of the screw 91 may be adjusted in the vertical direction within the long hole 28 of the door end vertical frame 24, and the position of the back plate 60 attached to the attachment surface portion 245 may be adjusted in the vertical direction. Since the lock receiver main body 70 and the lock receiver cover 80 move vertically together with the back plate 60, the position of the lock receiver device 50 can be adjusted vertically, and the positions of the openings 71 and 81 can be moved vertically. At this time, the vertical adjustment amount of the back plate 60 is set by the vertical length of the long hole 28, and further, the vertical adjustment amount of the lock receiver main body 70 disposed within the frame opening 25 is set by the height dimension H1 of the frame opening 25 and the height dimension H21 of the lock receiver main body 70. In the present embodiment, since all the adjustment amounts are 3 mm, the lock receiver device 50, that is, the openings 71 and 81, can be adjusted 3 mm in the vertical direction. In FIG. 8(A), since the screw 91 is moved to the upper end of the long hole 28, the openings 71 and 81 are located at the uppermost position. In FIG. 8(B), since the screw 91 is moved to the lower end of the long hole 28, the openings 71 and 81 are located at the lowermost position.

[0021] To adjust the positions of the openings 71 and 81 in the depth direction, since the position of the screw 92 can be adjusted in the depth direction within the long holes 73 and 83 of the lock receiver main body 70 and the lock receiver cover 80, the lock receiver main body 70 and the lock receiver cover 80 may be adjusted in the depth direction with respect to the back plate 60. Since the lock receiver main body 70 and the lock receiver cover 80 both move in the depth direction with respect to the back plate 60, the positions of the openings 71 and 81 can be moved in the depth direction. At this time, the adjustment amount in the prospective direction of the ingot receiver main body 70 and the ingot receiver cover 80 is set by the length in the prospective direction of the long holes 73 and 83. Further, the adjustment amount in the prospective direction of the ingot receiver main body 70 disposed within the frame opening 25 is set by the width dimension W1 of the frame opening 25 and the width dimension W21 of the ingot receiver main body 70. In this embodiment, since the adjustment amount is 3 mm in all cases, the openings 71 and 81 can be adjusted by 3 mm in the prospective direction. In FIG. 8(A), since the ingot receiver main body 70 and the ingot receiver cover 80 are moved to the outdoor side so that the screw 92 is positioned at the indoor-side end of the long holes 73 and 83, the openings 71 and 81 are located at the outermost outdoor side. In FIG. 8(B), since the ingot receiver main body 70 and the ingot receiver cover 80 are moved to the indoor side so that the screw 92 is positioned at the outdoor-side end of the long holes 73 and 83, the openings 71 and 81 are located at the outermost indoor side.

[0022] [Operational Effects of the First Embodiment] According to the fitting 1 of the first embodiment, the ingot receiver device 50 is composed of the back plate 60, the ingot receiver main body 70, and the ingot receiver cover 80. The back plate 60 is attached to the back surface of the attachment surface portion 245 of the door-end vertical frame 24 so as to be vertically position-adjustable. The screws 92 inserted into the long holes 73 and 83 of the ingot receiver main body 70 and the ingot receiver cover 80 are screwed into the back plate 60, and the ingot receiver main body 70 and the ingot receiver cover 80 are attached to the back plate 60 so as to be position-adjustable in the prospective direction. Therefore, the positions of the openings 71 and 81 can be adjusted in two directions, the vertical direction and the prospective direction. Further, since the openings 71 and 81 are arranged to overlap in a front view, the ingot receiver main body 70 is not exposed from the opening 81 of the ingot receiver cover 80, and only the ingot receiver cover 80 is exposed on the prospective surface of the door-end vertical frame 24. Therefore, the design property of the ingot receiver device 50 can be improved. Since the ingot receiver cover 80 disposed on the surface of the attachment surface portion 245 of the door-end vertical frame 24 is a thin plate with a small thickness dimension, the protruding amount from the surface of the attachment surface portion 245 to the surface of the ingot receiver cover 80 can be reduced, and the clearance between the door-end vertical frame 34, the door-end vertical frame 24, and the ingot receiver cover 80 can be ensured. Therefore, it is also possible to prevent the door-end vertical frame 34 from interfering with the door-end vertical frame 24 when the door 3 is opened and closed. By making the height dimension H1 and width dimension W1 of the frame opening 25 formed in the mounting surface portion 245 larger than the height dimension H21 and width dimension W21 of the lock receiver main body 70, the lock receiver main body 70 can be arranged within the frame opening 25. Thus, the back plate 60, the lock receiver main body 70, and the lock receiver cover 80 can be arranged in close contact with each other in the thickness direction, and the back plate 60 can also be attached in close contact with the back surface of the mounting surface portion 245. For this reason, the back plate 60, the lock receiver main body 70, and the lock receiver cover 80 can be configured by simply processing each opening 61, 71, 81, elongated holes 73, 83, etc. in a simple rectangular plate material, so that the cost of the lock receiver device 50 can be reduced. Furthermore, since the lock receiver main body 70 is in close contact with the lock receiver cover 80, the distance from the lock case 40 can be shortened. For this reason, the latch bolt 41 and the dead bolt 42 protruding from the lock case 40 can surely engage with the opening 71, and each bolt 41, 42 engages with the opening 71 at a position closer to the base end side, which is advantageous in terms of strength.

[0023] [Second Embodiment] Next, the fitting 1B of the second embodiment will be described with reference to FIGS. 9 to 14. In the second embodiment, the shape of the frame opening 25B formed in the mounting surface portion 245 of the door end vertical frame 24 is different, and furthermore, some configurations of the back plate 60B, the lock receiver main body 70B, and the lock receiver cover 80B that constitute the lock receiver device 50B are different. For this reason, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. The fitting 1B is a single-leaf door including the same door frame 2 and door leaf 3 as those in the first embodiment. Since the door frame 2 is the same as that in the first embodiment except that the shape of the frame opening 25B formed in the mounting surface portion 245 of the door end vertical frame 24 is different, the description thereof is omitted. Also, since the door leaf 3 has the same configuration as that in the first embodiment, the description thereof is omitted.

[0024] As shown in Fig. 10, the frame opening 25B includes a first opening 251 that is rectangular and long in the vertical direction, and second openings 252 that are formed continuously in the vertical direction from the upper and lower ends of the first opening 251, respectively. Let the height dimension of the first opening 251 be H41, and the height dimension from the upper end of the upper second opening 252 to the lower end of the lower second opening 252, that is, the overall height dimension of the frame opening 25B, be H42. Let the width dimension of the first opening 251 be W41, and the width dimension of the second opening 252 be W42. In the second embodiment, since the lock receiver body 70B is not arranged within the frame opening 25B, the size of the frame opening 25B is made smaller than that of the frame opening 25 in the first embodiment. For this reason, the height dimension H42 of the frame opening 25B is set to be smaller than the height dimension H1 of the frame opening 25, and the width dimension W41 of the frame opening 25B is set to be smaller than the width dimension W1 of the frame opening 25. In the attachment surface portion 245, long holes 28 similar to those in the first embodiment are formed above and below the frame opening 25B, respectively.

[0025] [Lock Receiver Device] As shown in Fig. 9, the lock receiver device 50B includes a back plate 60B, a lock receiver body 70B, and a lock receiver cover 80B.

[0026] [Back Plate] As shown in Fig. 11, the back plate 60B is composed of a rectangular metal plate 65 and a spacer 66 fixed to the surface of the rectangular plate 65. Since the rectangular plate 65 is the same steel rectangular plate as the back plate 60 in the first embodiment, the same reference numeral is given and the description is omitted. The spacer 66 is a ring-shaped component in which a screw hole 67 continuous with the screw hole 62 is formed, and is fixed to the rectangular plate 65 by welding or the like. As shown in Fig. 9, the back plate 60B is disposed on the back side of the mounting surface portion 245, that is, inside the hollow portion of the door end vertical frame 24. Then, by bringing the spacer 66 into contact with the back surface of the mounting surface portion 245 and screwing the screw 91 from the long hole 28 into the screw hole 67 of the spacer 66 and the screw hole 62 of the rectangular plate material 65, the back plate 60B is attached to the mounting surface portion 245. At this time, since the long hole 28 is long in the vertical direction, the height position of the back plate 60B can be adjusted by loosening the screw 91 and moving it within the long hole 28. For example, in the present embodiment, the back plate 60B can be moved about 3 mm in the vertical direction (the Y-axis direction, which is the first direction). Further, the rectangular plate material 65 of the back plate 60B is disposed at a distance from the back surface of the mounting surface portion 245 by the thickness dimension of the spacer 66 (for example, 2.0 mm).

[0027] [Lock receiver body] As shown in Fig. 12, the lock receiver body 70B includes a rectangular plate material 75 made of metal and a spacer 76 fixed to the surface of the rectangular plate material 75. Since the rectangular plate material 75 is the same stainless steel rectangular plate material as the lock receiver body 70 of the first embodiment, the same reference numerals are given and the description thereof is omitted. The spacer 76 is a liner plate formed in a rectangular plate shape and is fixed to the rectangular plate material 75 by welding or the like. The width dimension of the spacer 76 is set to W23, which is the same as the width dimension of the long hole 73. As shown in Fig. 9, the lock receiver body 70B is disposed on the back side of the mounting surface portion 245, that is, inside the hollow portion of the door end vertical frame 24. The spacer 76 is disposed in the second opening portion 252 of the frame opening 25B. At this time, the width dimension W23 of the spacer 76 is made smaller than the width dimension W42 of the second opening portion 252, and the spacer 76 is configured to be movable about 3.0 mm in the prospective direction (the Z-axis direction, which is the second direction) within the second opening portion 252. Each elongated hole 73 is disposed at a position overlapping with the second opening 252, and the screw receiver body 70B is attached to the back plate 60B by a screw 92 that is screwed into the screw hole 63 of the back plate 60B from the screw receiver cover 80B, which will be described later, through the second opening 252 and the elongated hole 73. At this time, since the elongated hole 73 is long in the prospective direction, the position of the screw receiver body 70B in the prospective direction can be adjusted by loosening the screw 92 and moving it within the elongated hole 73. For example, in the present embodiment, the screw receiver body 70B can move approximately 3 mm in the prospective direction with respect to the back plate 60.

[0028] [Screw Receiver Cover] The screw receiver cover 80B is different from the screw receiver cover 80 of the first embodiment only in the width dimension, and the other configurations are the same, so the same reference numerals are used and the description is omitted. That is, as shown in FIG. 13, the screw receiver cover 80B is a rectangular plate made of stainless steel. The height dimension H31 in the vertical direction is the same as that of the screw receiver cover 80, but the width dimension W33 in the prospective direction is smaller than the width dimension W31 of the screw receiver cover 80. Also, the thickness dimension of the screw receiver cover 80B is 0.5 mm, the same as that of the screw receiver cover 80 of the first embodiment. The screw receiver cover 80B is fastened together with the screw receiver body 70B by a screw 92 that is screwed into the screw hole 63 of the back plate 60B through the elongated hole 83, and is attached to the back plate 60B. At this time, since the elongated hole 83 is long in the prospective direction, the position of the screw receiver cover 80B in the prospective direction can be adjusted by loosening the screw 92 and moving it within the elongated hole 83. For example, in the present embodiment, the screw receiver cover 80B can move approximately 3 mm in the prospective direction (the Z-axis direction and the second direction) with respect to the back plate 60B, the same as the screw receiver body 70B. The height dimension H31 and width dimension W33 of the screw receiver cover 80B are set to be larger than the height dimension H42 and width dimension W41 of the frame opening 25B, so as to be able to hide the frame opening 25B. Also, the screw receiver cover 80B abuts on the surface of the spacer 76 of the screw receiver body 70B and is disposed across the surface of the attachment surface portion 245.

[0029] [Position Adjustment of Screw Receiver Device] Next, the position adjustment of the ingot receiver device 50B will be described with reference to FIG. 14. Also in this embodiment, similar to the first embodiment, the positions of the openings 71 and 81 of the ingot receiver main body 70B and the ingot receiver cover 80B can be adjusted. To adjust the positions of the openings 71 and 81 in the vertical direction, similar to the first embodiment, within the elongated hole 28 of the door-end vertical frame 24, the position of the screw 91 is adjusted in the vertical direction, and the position of the back plate 60B attached to the attachment surface portion 245 is adjusted in the vertical direction. Also in this embodiment, since the vertical adjustment amounts of the back plate 60B, the ingot receiver main body 70B, and the ingot receiver cover 80B are set by the vertical length of the elongated hole 28, the ingot receiver device 50B, that is, the openings 71 and 81, can be adjusted by 3 mm in the vertical direction. In FIG. 14(A), since the screw 91 is moved to the upper end of the elongated hole 28, the openings 71 and 81 are located at the uppermost position. In FIG. 14(B), since the screw 91 is moved to the lower end of the elongated hole 28, the openings 71 and 81 are also located at the lowermost position.

[0030] To adjust the positions of the openings 71 and 81 in the prospective direction, similar to the first embodiment, within the elongated holes 73 and 83 of the ingot receiver main body 70B and the ingot receiver cover 80B, the position of the screw 92 can be adjusted in the prospective direction, so the ingot receiver main body 70B and the ingot receiver cover 80B may be adjusted in the prospective direction with respect to the back plate 60. At this time, the prospective adjustment amounts of the ingot receiver main body 70 and the ingot receiver cover 80 are set by the prospective lengths of the elongated holes 73 and 83, similar to the first embodiment, and the prospective adjustment amount of the spacer 76 disposed within the second opening portion 252 of the frame opening 25B is set by the width dimension W42 of the second opening portion 252 and the width dimension W23 of the spacer 76. Since both are adjustment amounts of 3 mm in this embodiment, the openings 71 and 81 can be adjusted by 3 mm in the prospective direction. In FIG. 14(A), since the ingot receiver main body 70B and the ingot receiver cover 80B are moved to the outdoor side so that the screw 92 is located at the indoor-side end of the elongated holes 73 and 83, the openings 71 and 81 are located at the outermost outdoor position. In FIG. 14(B), since the ingot receiver main body 70B and the ingot receiver cover 80B are moved to the indoor side so that the screw 92 is located at the outdoor-side end of the elongated holes 73 and 83, the openings 71 and 81 are located at the innermost indoor position.

[0031] [Operational Effects of the Second Embodiment] According to the second embodiment, the same operational effects as those of the first embodiment can be achieved. That is, since the latch receiver device 50B is composed of the back plate 60B, the latch receiver main body 70B, and the latch receiver cover 80B, the positions of the openings 71 and 81 into which the latch bolt 41 and the dead bolt 42 are inserted and engaged can be adjusted in two directions, the vertical direction and the prospective direction. Moreover, since only the latch receiver cover 80B is exposed on the prospective surface of the door end vertical frame 24, the design property of the latch receiver device 50B can be improved. Since the latch receiver cover 80B is a thin plate with a small thickness dimension, similar to the first embodiment, a clearance can be ensured between the door end vertical stile 34, the door end vertical frame 24, and the latch receiver cover 80B, and it is also possible to prevent the door end vertical stile 34 from interfering with the door end vertical frame 24 when the door 3 is opened and closed. Since the latch receiver main body 70B is arranged on the back side of the mounting surface portion 245 and there is no need to arrange the latch receiver main body 70B within the frame opening 25B, the size of the frame opening 25B can be minimized to the necessary minimum, and the rigidity of the door end vertical frame 24 can be improved. Since the spacer 76 provided on the latch receiver main body 70B is brought into contact with the back surface of the latch receiver cover 80B, and the spacer 66 provided on the back plate 60B is brought into contact with the back surface of the mounting surface portion 245, the latch receiver device 50B can be attached to the door end vertical frame 24 without rattling. Further, since the spacer 76 of the latch receiver main body 70B is arranged in the second opening portion 252 of the frame opening 25B, particularly, when the latch receiver main body 70B is moved to the outdoor side or the indoor side and the side surface of the spacer 76 is brought into contact with the second opening portion 252, a part of the force applied to the latch receiver main body 70B from the latch bolt 41 and the dead bolt 42 can also be directly supported by the mounting surface portion 245 via the spacer 76.

[0032] [Modification Example] The hardware of the present invention is not limited to the outward-opening door of the above embodiment, and may be an inward-opening door or a sliding door. The present invention can be used for various hardware having lock parts and latch receiver parts, such as an entrance door, a side door, and an interior door. Further, the latch receiver part is not limited to being attached to the prospective surface of the vertical frame, and may be attached to the outdoor surface of the vertical frame, such as in the case of an offset sliding door. Furthermore, the present invention is not limited to a fitting in which a lock receiver component is attached to a vertical frame, and can also be used for fittings in which a lock receiver component is attached to an upper frame or a lower frame, such as a French window receiver. Also, the fitting is not limited to a door, and can be used for various fittings having a door lock.

[0033] The fastening components for attaching the back plates 60, 60B to the attachment surface portion 245, and the fastening components for attaching the lock receiver bodies 70, 70B and the lock receiver covers 80, 80B to the back plates 60, 60B are not limited to screws 91, 92, and may be bolts and nuts or the like, as long as each member can be fastened to each other. The back plates 60, 60B are not limited to the configuration of the above-described embodiment. For example, the back plate is not limited to being formed in a plate shape, and may have a structure that closes the back surface side of the openings 71, 81, such as being formed in a U-shaped cross section or a box shape. Also, the back plate 60B is not limited to having the spacer 66 fixed thereto, and may not have the spacer 66. The back plates 60, 60B may be attached to the door vertical frame 24 so as to be position-adjustable in the second direction (prospective direction), and the lock receiver bodies 70, 70B and the lock receiver covers 80, 80B may be attached to the back plates 60, 60B so as to be position-adjustable in the first direction (vertical direction). When attaching the back plate to the attachment surface portion 245 with bolts and nuts, a long hole extending in the vertical direction may be formed in the back plate, the bolt may be inserted through the through hole formed in the attachment surface portion 245 and the long hole of the back plate, and fastened to the nut disposed on the back side of the back plate, so that the back plate can be attached so as to be position-adjustable in the vertical direction. Similarly, when attaching the lock receiver body and the lock receiver cover to the back plate with bolts and nuts, a long hole extending in the prospective direction may be formed in the back plate, the bolt may be inserted through the through holes formed in the lock receiver body and the lock receiver cover and the long hole of the back plate, and fastened to the nut disposed on the back side of the back plate, so that the lock receiver body and the lock receiver cover can be attached to the back plate so as to be position-adjustable in the prospective direction. In the first embodiment, since the lock receiver body 70 is disposed within the frame opening 25 and is integrally moved in close contact with the lock receiver cover 80, the lock receiver body 70 and the lock receiver cover 80 may be integrated by welding, an adhesive, or the like, or the component having the lock receiver body 70 and the lock receiver cover 80 may be integrally molded.
