DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1 and 2, the fixture 1 of this embodiment is a single-leaf door comprising a door frame 2, which is a fixture frame attached to an opening of a building, and a door 3, which is a shoji screen attached within the door frame 2 so as to be able to be opened and closed freely. In the following description, the left-right direction of the fitting 1 is the X-axis direction, the up-down direction of the fitting 1 is the Y-axis direction, and the front direction of the fitting 1 is the Z-axis direction. The X, Y, and Z axis directions are mutually perpendicular.

[0010] As shown in FIG. 1, the door frame 2 is a four-sided frame formed by joining an upper frame 21, a lower frame 22, a hanging vertical frame 23, and a door end vertical frame 24, which is a door end frame, into a square frame shape. As shown in Figure 2, the door end vertical frame 24 comprises a projection surface portion 241 arranged along the Z-axis direction (projection direction), a door stop portion 242 extending from the projection surface portion 241 toward the hanging vertical frame 23, i.e., in the X-axis direction, an exterior surface portion 243 which is a first side portion extending from the projection surface portion 241 toward the hanging vertical frame 23, an interior surface portion 244 which is a second side portion extending from the projection surface portion 241 toward the hanging vertical frame 23, and a mounting surface portion 245 which connects the exterior surface portion 243 and the interior surface portion 244. The exterior surface 243 extends linearly from the visible surface 241 in the visible direction of the door end vertical frame 24, that is, in the X-axis direction. On the other hand, the interior surface 244 extends from the visible surface 241 in the X-axis direction, further extends to the exterior side in the Z-axis direction, and further extends in the X-axis direction to be connected to the mounting surface 245, and is generally formed in a substantially Z-shaped cross section. In addition, in the mounting surface portion 245 of the vertical door end frame 24, the up-down direction (Y-axis direction) is defined as the first direction, and the prospective direction (Z-axis direction) is defined as the second direction. Therefore, the second direction is a direction along the surface of the mounting surface portion 245, and is a direction perpendicular to the up-down direction (first direction), which is the longitudinal direction of the vertical door end frame 24.

[0011] As shown in FIGS. 3 and 4, the mounting surface portion 245 has a frame opening 25 formed therein. A height dimension H1 of the frame opening 25 in the first direction (Y-axis direction) is set to a dimension slightly larger than a height dimension H2 of a front part 80 described later. Specifically, the dimension is set to a dimension that allows the front part 80 to be placed therein and allows the frame opening 25 to restrict movement of the front part 80 in the Y-axis direction. A width dimension W1 of the frame opening 25 in the second direction (Z-axis direction) is the same as the width dimension of the mounting surface portion 245, and is set to a smaller dimension than a width dimension W2 of the front part 80. That is, the frame opening 25 is formed over the entire width direction of the mounting surface portion 245, and as shown in Fig. 4, end faces of the exterior surface portion 243 and the interior surface portion 244 are exposed in the frame opening 25 portion. The door stop portion 242 is formed with a retaining groove that opens to the outside of the room, and a seal material 26 that abuts against the door 3 to ensure airtightness is attached to this retaining groove. A synthetic resin cover material 27 is attached to the vertical door end frame 24 to cover the surface of the vertical door end frame 24 exposed to the interior. Note that the seal material 26 and the cover material 27 are not shown in Figures 3(B) and 4(B). The hanging vertical frame 23 has the same structure as the door end vertical frame 24, so its explanation is omitted.

[0012] As shown in Figure 1, the door 3 is configured with a frame 30 formed by an upper frame 31, a lower frame 32, a hanging vertical frame 33, and a door end vertical frame 34, and a double-glazed glass 35 that is a surface material incorporated inside the frame 30. The frame 30 is a so-called vertical frame in which the small edges of the upper frame 31 and the lower frame 32 are abutted against the hanging vertical frame 33 and the door end vertical frame 34 and fixed. 1 and 2, the hanging vertical frame 33 is attached to the hanging vertical frame 23 of the door frame 2 via a hinge 39. This allows the door 3 to be freely opened and closed relative to the door frame 2. Since the fitting 1 in this embodiment is an outward-opening door, the door 3, which is a paper screen, is installed to open to the outside of the room and close to the inside of the room. The hinge 39 is a flag hinge that includes a frame side hinge 391 fixed to the hanging vertical frame 23 and a frame side hinge 392 attached to the hanging vertical frame 33.

[0013] A lock case 40, which is a lock part, and a lever handle 36 are attached to the vertical middle position of the door end vertical frame 34. A lock receiving part 50 is attached to the vertical middle position of the door end vertical frame 24, with which a latch bolt 41 and a deadbolt 42, which are lock bolts that protrude from and retract into the lock case 40, engage.

[0014] [Lock receiving parts] As shown in FIGS. 2 and 3, the lock receiving part 50 includes a liner 60, a back plate part 70, and a front part 80. As shown in FIG. As shown in FIG. 5, the liner 60 includes a liner body 61 and a reinforcing plate 62. 4, the liner body 61 is formed of a rectangular metal plate longer in the vertical direction (Y-axis direction, first direction) than the height dimension H1 of the frame opening 25, and includes a rectangular opening 63 that is longer in the vertical direction, a first long hole 64 formed continuously from the upper end of the opening 63 upward, and a second long hole 65 formed on the opposite side of the opening 63 to the first long hole 64, i.e., below the opening 63. Furthermore, the liner body 61 is formed with through holes 66 at a position above the first long hole 64 and a position below the second long hole 65. Furthermore, the liner body 61 is formed with positioning holes 67 for the reinforcing plate 62 at oblique positions sandwiching the through hole 66. The first elongated hole 64 and the second elongated hole 65 have the same width dimension W3. The width dimension W4 of the opening 63 is larger than the width dimension W3. The reinforcing plate 62 is a metal plate having a thickness greater than that of the liner body 61, and is fixed to the upper and lower ends of the liner body 61 by welding or the like. The reinforcing plate 62 is formed with screw holes 68 that are concentric with the through holes 66 and have a smaller diameter than the through holes 66. The reinforcing plate 62 also has a positioning protrusion 69 that is inserted into a positioning hole 67 of the liner body 61. The height dimension between the upper and lower reinforcing plates 62, i.e., the height dimension of the region where only the liner body 61 is provided, is the same as the height dimension H1 of the frame opening 25.

[0015] The liner 60 having the above configuration is formed by welding and fixing the liner body 61 and the reinforcing plate 62 in a state where the positioning protrusions 69 of the reinforcing plate 62 are inserted into the positioning holes 67 of the liner body 61 and positioned. The liner 60 is not limited to being composed of the liner body 61 and the reinforcing plate 62, and may be composed of a single plate material having a thickness that allows the screw holes 68 to be formed. However, if the liner 60 is configured as in this embodiment, since the screw holes 68 are formed in the reinforcing plate 62, there is no need to increase the thickness dimension of the liner body 61, and the cost of the liner 60 can be reduced. As shown in Fig. 4, the liner 60 is disposed across the frame opening 25 on the back side of the mounting surface portion 245 of the door end vertical frame 24, that is, on the hollow portion side defined by the projected surface portion 241, the exterior surface portion 243, the interior surface portion 244, and the mounting surface portion 245. The liner 60 is fixed to the mounting surface portion 245 by screwing the flat head screws 91, which are inserted through the through holes formed above and below the frame opening 25 of the mounting surface portion 245, into the screw holes 68 via the through holes 66. At this time, the opening 63, the first elongated hole 64, and the second elongated hole 65 of the liner body 61 are exposed to the frame opening 25 of the mounting surface portion 245.

[0016] As shown in FIG. 6, the back plate component 70 is a metal plate manufactured by bending using a press process, and includes a pair of upper and lower base portions 71 and a pair of connecting portions 72 that connect the base portions 71 together. A first screw hole 73 and a press pilot hole 75 are formed in the upper base portion 71, and a second screw hole 74 and a press pilot hole 75 are formed in the lower base portion 71. The first screw hole 73 and the second screw hole 74 are formed in the burred portion of the base portion 71. The connecting portion 72 has an inclined surface 76 formed on both the upper and lower ends. The height dimension of the back plate component 70 is set to a height dimension H2 that is the same as that of the front component 80 described below. The width dimension W5 of the back plate component 70 is set to a dimension smaller than the width dimension W4 of the opening 63 of the liner 60.

[0017] The front part 80 is a part also called a striker that receives the latch bolt 41 and the deadbolt 42 of the lock case 40. In this embodiment, the front part 80 is a metal plate manufactured by bending through press working, as shown in Fig. 7, and includes a main body part 81 and side parts 82 bent from both side surfaces of the main body part 81. The main body portion 81 has a thickness dimension that is the same as that of the mounting surface portion 245, and this main body portion 81 is formed with a lock hole 83, a first insertion hole 84, a second insertion hole 85, a first folded portion 86, and a second folded portion 87. The lock hole 83 is a hole (strike hole) into which the latch bolt 41 and dead bolt 42 of the lock case 40 are inserted, and in this embodiment, is formed with a size that allows both the latch bolt 41 and the dead bolt 42 to be inserted. As shown in Fig. 3, the lock hole 83 is set to a size smaller than the opening 63 of the liner 60. Specifically, the opening 63 of the liner 60 is set so that the lock hole 83 fits within the range of the opening 63 even if the front part 80, i.e., the lock hole 83, is moved in the prospective direction (Z-axis direction) or the front part 80 is attached upside down to move the lock hole 83 in the vertical direction (Y-axis direction), as described below. The first insertion hole 84 and the second insertion hole 85 are countersunk holes in which flat head screws 92 for fixing the front component 80 are placed. The first folded portion 86 and the second folded portion 87 are formed by bending both side surfaces of the lock hole 83 along the up-down direction toward the rear surface side.

[0018] A first distance L1 from the center of the first insertion hole 84 of the front part 80 to the upper end of the lock hole 83 and a second distance L2 from the center of the second insertion hole 85 to the lower end of the lock hole 83 are different dimensions. In this embodiment, the second distance L2 is set to a dimension 1 mm longer than the first distance L1.

[0019] [How to install the lock receiving parts] Next, the procedure for attaching the lock receiving part 50 to the attachment surface portion 245 of the door end vertical frame 24 will be described with reference to FIG. First, the liner 60 is attached to the back surface of the mounting surface portion 245. Since the width dimension of the liner 60 is smaller than the width dimension W1 of the frame opening 25, the liner 60 can be inserted from the frame opening 25 to the back surface side of the mounting surface portion 245, and then the liner 60 is attached to the mounting surface portion 245 using the countersunk screws 91. In addition, the back plate component 70 and the front component 80 are connected with a flat head screw 92, which is a fastening component. Specifically, the flat head screw 92 is inserted into the first insertion hole 84 of the front component 80, and the flat head screw 92 is screwed into the first screw hole 73 of the back plate component 70, thereby connecting the back plate component 70 and the front component 80. That is, the flat head screw 92 is attached only to the first insertion hole 84 and the first screw hole 73, and the back plate component 70 and the front component 80 are connected with only the single flat head screw 92, as shown in FIG. 8(A).

[0020] Next, as shown in FIGS. 8(A) and (B), the lower end of the back plate component 70 is inserted through the opening 63 of the liner 60. 8(C), the entire back plate component 70 is inserted through the opening 63 of the liner 60 and placed on the back side of the liner 60. At this time, since the inclined surface 76 is formed on the connecting portion 72 of the back plate component 70, the upper end side of the connecting portion 72 does not interfere with the opening 63, and can be smoothly inserted.

[0021] 8(D), the back plate component 70 and the front component 80 are moved upward relative to the liner 60, and the flat head screws 92 are moved from the openings 63 into the first elongated holes 64. At this time, the upper and lower ends of the front component 80 are moved to a position where they fit within the frame openings 25 of the mounting surface portion 245. 8(E), flat head screws 92 are inserted from the second insertion holes 85 of the front part 80 and screwed into the second screw holes 74 via the second elongated holes 65. When the flat head screws 92 are tightened, the back plate part 70 and the front part 80 are crimped onto the back and front surfaces of the liner body 61 of the liner 60. In this manner, the lock receiving part 50 is attached to the frame opening 25 of the mounting surface portion 245.

[0022] [Adjusting the position of the front part in the projection direction] Next, the position adjustment of the front part 80 of the lock receiving part 50 in the projection direction (out-of-plane direction) will be described with reference to Fig. 9. The out-of-plane direction is the direction perpendicular to the surface of the door 3, that is, the Z-axis direction (second direction), and is the projection direction of the fitting 1, that is, the indoor / outdoor direction. Therefore, adjusting the position of the front part 80 in the projection direction means adjusting the position of the front part 80 in the Z-axis direction. The adjustment of the projection direction of the front part 80 is performed by adjusting the position of the flat head screw 92 in the first long hole 64 and the second long hole 65 of the liner 60. That is, the width dimension W3 in the projection direction of the first long hole 64 and the second long hole 65 is set to a dimension larger than the nominal diameter W6 of the flat head screw 92, and the position of the flat head screw 92 can be adjusted in the first long hole 64 and the second long hole 65. For example, when the width dimension W3 in the projection direction of the first long hole 64 and the second long hole 65 is 9 mm and the nominal diameter W6 of the flat head screw 92 is 4 mm, the front part 80 and the back plate part 70 can be adjusted in the projection direction by about 5 mm relative to the liner 60. Therefore, if the projection direction of the front part 80 needs to be adjusted after the door frame 2 to which the lock receiving part 50 is attached and the door 3 to which the lock case 40 is attached are installed at the construction site, the flat head screw 92 is loosened and the front part 80 and the back plate part 70 are moved in the Z-axis direction. This allows the position of the flat head screw 92 to be adjusted in the Z-axis direction within the first elongated hole 64 and the second elongated hole 65 of the liner 60, and by tightening the flat head screw 92 after adjusting the position, the front component 80 and the back plate component 70 are pressed against the liner 60, and the position of the front component 80 in the prospective direction, i.e., the position of the lock hole 83 in the prospective direction, can be adjusted. The adjustment range of the position of the front part 80 in the forward direction is regulated by the position where one side portion 82 of the front part 80 abuts either the exterior surface portion 243 or the interior surface portion 244, or the position where the countersunk screw 92 abuts one side of the first long hole 64 and the second long hole 65.

[0023] [Strike direction position adjustment] Next, the position adjustment of the front part 80 in the facing direction will be described with reference to Fig. 10. Here, the facing direction is the direction perpendicular to the surface of the mounting surface portion 245 of the vertical door end frame 24, that is, the left-right direction (X-axis direction) of the fitting 1, and adjusting the position of the front part 80 in the facing direction means adjusting the position of the front part 80 in the left-right direction (X-axis direction). The facing direction of the front part 80 can be adjusted by disposing a spacer 100 between the front part 80 and the liner 60 . That is, as shown in FIG. 3, when the spacer 100 is not arranged with the front part 80 directly abutting the liner 60, the front part 80 is arranged in a position where its surface coincides with the surface of the mounting surface portion 245. On the other hand, as shown in Fig. 10(A), when a spacer 100 is placed between the front part 80 and the liner 60, the surface of the front part 80 can be adjusted to a position closer to the door end vertical frame 34 than the surface of the mounting surface portion 245 by the thickness dimension of the spacer 100. Therefore, the position of the front part 80 in the front direction can be adjusted in two stages depending on whether or not the spacer 100 is placed.

[0024] As shown in FIG. 10(B), the spacer 100 is arranged between the upper and lower ends of the front part 80 and the lock hole 83, and is composed of a rectangular plate material with slits 101 formed therein through which the flat head screws 92 can be inserted. Therefore, after the door frame 2 and the door 3 are installed at the construction site, it is checked whether the front part 80 needs to be adjusted in the front direction. If the adjustment is necessary, the flat head screw 92 is loosened to provide a space between the front part 80 and the liner 60, the spacer 100 is inserted into the space from above and below, and the flat head screw 92 is placed in the slit 101 to place the spacer 100 between the front part 80 and the liner 60. Then, the flat head screw 92 is tightened to press the front part 80 and the back plate part 70 against the spacer 100 and the liner 60, and the front part 80 can be adjusted in the front direction. If multiple types of spacers 100 with different thicknesses are prepared, the front part 80 can be adjusted in multiple steps.

[0025] [Up and down adjustment of lock hole] Next, adjustment of the vertical position of the lock hole 83 of the front part 80 will be described with reference to Fig. 11. The vertical position of the front part 80 cannot be adjusted because it is restricted by the front part 80 or the spacer 100 abutting against the lower end surface of the frame opening 25 of the mounting surface portion 245. For this reason, in this embodiment, the vertical position of the lock hole 83 in the front part 80 is shifted and the front part 80 is attached to the liner 60 upside down, so that the vertical position of the lock hole 83 can be adjusted in two stages. In this embodiment, the deadbolt 42 of the lock case 40 is formed with a sickle lock 421 that protrudes from the deadbolt 42 when locked. This sickle lock 421 protrudes upward when the deadbolt 42 is locked while inserted in the lock hole 83 of the front part 80. At this time, a predetermined dimension (e.g., 3 mm) needs to be secured as the dimension from the upper end of the lock hole 83 to the upper end of the sickle lock 421, that is, the hook allowance L3 of the sickle lock 421. Here, as shown in FIG. 11(B), when the height position of the lock case 40 is lowered by dimension L0 (for example, 1 mm) due to the sagging of the door end vertical frame 34 compared to the height position of the lock case 40 in standard installation shown in FIG. 11(A), the hook allowance L3 of the sickle lock 421 becomes 1 mm smaller. In that case, as shown in FIG. 11(B), the front part 80 is turned upside down, and the second insertion hole 85 is arranged on the upper side and the first insertion hole 84 on the lower side. Since the second distance L2 is 1 mm longer than the first distance L1, the upper end position of the lock hole 83 in FIG. 11(B) is 1 mm lower than that in FIG. 11(A), and the hook allowance L3 of the sickle lock 421 can be secured to the same dimension (for example, 3 mm) as in standard installation.

[0026] [Effects of the embodiment] According to the fitting 1 of this embodiment, the liner 60 is attached to the back surface of the mounting surface portion 245 of the door end vertical frame 24, and the front part 80 and the back plate part 70 are fastened by screwing a flat head screw 92 into the back plate part 70 through the frame opening 25 formed in the mounting surface portion 245 and the first long hole 64 and the second long hole 65 formed in the liner 60 from the front part 80, so that the position of the front part 80 in which the lock hole 83 is formed can be adjusted in the expected direction (second direction). Therefore, unlike Patent Document 1, it is not necessary to expose the front base, the long hole, the left-right adjustment screw, and the left-right adjustment member in the opening of the front plate fixed immovably, and the size of the front part can be reduced. In addition, it is not necessary to form a long hole in the front part 80, and the through hole through which the flat head screw 91 for fixing the liner 60 is inserted does not need to be a long hole, and the liner 60 can be hidden by the front part 80, so that the design of the exposed surface of the lock receiving part 50 can be improved. Furthermore, as shown in FIG. 9, the thickness dimension of the main body 81 of the front part 80 is set to the same dimension as the thickness dimension of the mounting surface part 245. Therefore, by closely adhering the front part 80 to the surface of the liner 60, the surface of the front part 80 and the surface of the mounting surface part 245 can be made flush with each other. This ensures a large clearance between the end frame 34 and the end frame 24 when the door 3 is opened or closed, and also prevents the end frame 34 from interfering with the end frame 24 when the door 3 is opened or closed.

[0027] As shown in FIG. 10, by disposing the spacer 100 between the front part 80 and the liner 60, the position of the front part 80 can be adjusted in the front direction. Therefore, even if the door 3 is moved toward the hanging side from the standard construction state when the fitting 1 is installed on site, there is no need to adjust the position of the door 3 on the hanging side, and the adjustment can be performed simply by inserting the spacer 100 on the door end side, so that the adjustment work on site can be easily performed. In addition, by preparing spacers 100 with different thickness dimensions, the front part 80's position in the front direction can be easily adjusted in multiple stages. Furthermore, since the spacer 100 is disposed between the front part 80 and the liner 60 and is not exposed on the surface of the lock receiving part 50, the design of the lock receiving part 50 can be prevented from being deteriorated.

[0028] As shown in FIG. 11, the position of the lock hole 83 can be easily adjusted in the vertical direction by turning the front part 80 up and down. In addition, when the vertical dimension of the frame opening 25 is increased and the first long hole 64 and the second long hole 65 of the liner 60 are also elongated in the vertical direction to adjust the mounting position of the front part 80 in the vertical direction, a gap is generated between the frame opening 25 and the front part 80, and a part for closing this gap is required, which reduces the design of the lock receiving part 50. However, in this embodiment, since it is only necessary to turn the front part 80 up and down, the design of the lock receiving part 50 can be prevented from being reduced. Furthermore, since the front part 80 has a first folded portion 86 and a second folded portion 87 formed on both sides of the lock hole 83, the latch bolt 41 can be reliably guided even when the front part 80 is turned upside down.

[0029] By disposing the front part 80 in the frame opening 25, the movement of the front part 80 in the up and down direction can be restricted easily and stably. Since the width dimension W2 of the front part 80 is larger than the width dimension W1 of the mounting surface part, when the position of the front part 80 is adjusted in the prospective direction, the mounting surface part 245 can be reliably covered by the front part 80. Therefore, the frame opening 25 formed in the mounting surface part 245 can be prevented from being exposed, improving the design.

[0030] With the front part 80 and the back plate part 70 fastened with one flat head screw 92, the back plate part 70 can be inserted through the opening 63 of the liner 60, and with it positioned on the back side of the liner 60, the flat head screw 92 can be moved from the opening 63 to the first long hole 64, so that the back plate part 70 can be easily positioned on the back side of the liner 60 and the workability of installing the lock receiving part 50 can be improved.

[0031] [Variations] The fixture of the present invention is not limited to the outward opening door of the above embodiment, but may be an inward opening door or a sliding door, and the present invention can be used for various fixtures having lock parts and lock receiving parts such as front doors, back doors, interior doors, etc. Furthermore, the lock receiving parts are not limited to those attached to the visible surface of the vertical frame, but may be attached to the exterior surface of the vertical frame, as in the case of an offset sliding door. Furthermore, the present invention is not limited to fittings that have a lock receiving part attached to a vertical frame, but can also be used for fittings that have a lock receiving part attached to the top or bottom frame, such as French drop brackets.Furthermore, the fitting is not limited to doors, but can be used for various fittings that have a door end lock.

[0032] The fastening parts for fastening the front part and the back plate part are not limited to the flat head screws 92, but may be any parts capable of fastening the front part 80 and the back plate part 70 together, such as bolts. The back plate component 70 is not limited to the configuration of the above embodiment. For example, when a bolt is used as the fastening component, a nut may be used as the back plate component. In other words, the back plate component may be any component that can be fastened to the front component by a fastening component and can hold the liner between the front component and the back plate component.

[0033] In the above embodiment, the first distance L1 and the second distance L2 between the first insertion hole 84, the second insertion hole 85, and the lock hole 83 of the front part 80 are different, but they may be the same distance. In particular, when the deadbolt 42 is not provided with the sickle lock 421, and there is no need to adjust the vertical position of the lock hole 83 and there is no need to turn the front part 80 upside down, the distances L1 and L2 can also be set to the same distance. The configuration of the liner 60 is not limited to the above embodiment. For example, the first elongated hole 64 is not limited to being continuous with the opening 63, and may be formed discontinuously with the opening 63, similar to the second elongated hole 65. In this case, the back plate component 70 is arranged on the back side of the liner 60 using a jig or the like, and flat head screws 92 are inserted from the first insertion hole 84 and the second insertion hole 85 of the front component 80 into the first elongated hole 64 and the second elongated hole 65 independent of the opening 63, and then screwed into the first screw hole 73 and the second screw hole 74 of the back plate component 70.

[0034] [Summary of the invention] The fixture of the present invention comprises a fixture frame, a shoji screen that can be freely opened and closed within the fixture frame, a lock receiving part attached to the end frame of the fixture frame, and a lock part attached to the end frame of the shoji screen, wherein the end frame has a mounting surface part to which the lock receiving part is attached, and the lock part has a lock bolt that protrudes and retracts from the end frame, and the lock receiving part comprises a liner fixed to the back surface of the mounting surface part, a front part that is arranged on the front side of the liner and has a lock hole into which the lock bolt is inserted, and a back plate part that is arranged on the back side of the liner, and the front part and the back plate part are fastened to each other by fastening parts that are fastened to the back plate part from the front part through a frame opening formed in the mounting surface part and a long hole formed in the liner, and the fastening parts are arranged within the frame opening and the long hole so that their position can be adjusted in a second direction that is perpendicular to a first direction, which is the longitudinal direction of the end frame, and is a direction along the surface of the mounting surface part. According to the fitting of the present invention, a liner is attached to the reverse side of the mounting surface of the door frame, and the front and back components are fastened with fastening components that are fastened from the front component to the back component through a frame opening formed in the mounting surface and an elongated hole formed in the liner, and the fastening components are arranged to be position adjustable in a second direction within the frame opening and the elongated hole, so that the positions of the front and back components, i.e., the lock holes into which the lock bolts are inserted, can be adjusted in the second direction relative to the liner and door frame. For example, if the door frame is a vertical frame, the first direction, which is the longitudinal direction of the door frame, is the up-down direction, and if the mounting surface of the door frame is the inner peripheral surface of the fitting frame, i.e., the projected surface, the second direction is the projected direction, so that the positions of the front and back components, i.e., the lock holes, can be adjusted in the projected direction relative to the liner and door frame. Therefore, there is no need to expose the liner inside the lock hole of the front part, and the frame opening of the door frame and the long hole of the liner can be covered with the front part, improving the design of the lock receiving part.

[0035] In the fitting of the present invention, it is preferable that a spacer is disposed between the front part and the liner. According to the fitting of the present invention, a spacer is placed between the front part and the liner, so the position of the front part can be adjusted in a direction perpendicular to the first and second directions. For example, if the door frame is a vertical frame, the first direction is the up-down direction, and the second direction is the forward direction, the position of the front part can be moved in the forward direction of the door frame, and it can be brought closer to the door frame of the shoji screen. Therefore, the position of the front part in the forward direction can be easily adjusted depending on the presence or absence of a spacer and the thickness dimension of the spacer, and furthermore, since the spacer is placed between the front part and the liner and is not exposed, a decrease in design can be prevented.

[0036] In the building fixture of the present invention, it is preferable that the front part has the lock hole, and a first insertion hole and a second insertion hole formed at a distance in the first direction from the lock hole and through which the fastening part is inserted, and that in the first direction, a first distance from the first insertion hole to the lock hole and a second distance from the second insertion hole to the lock hole are different distances. According to the fitting of the present invention, the lock hole is formed shifted toward one of the first and second insertion holes through which the fastening parts are inserted, so that the position of the lock hole in the first direction (for example, the vertical direction) can be easily changed by inverting the mounting direction of the front part by 180 degrees. In addition, since the direction of the front part is changed, there is no need to increase the dimension of the frame opening in the first direction, and the design can be prevented from being deteriorated.

[0037] In the building fixture of the present invention, it is preferable that the door frame has the mounting surface portion and a first side portion and a second side portion extended from both side surfaces of the mounting surface portion along the first direction, and the dimension of the frame opening in the first direction is set to a size that allows the front part to be placed, and the dimension in the second direction is set to the same dimension as the mounting surface portion, and the dimension of the front part in the second direction is larger than the width dimension in the second direction of the mounting surface portion. According to the fittings of the present invention, the front part can be placed in the frame opening, and by making the thickness dimension of the front part the same as the thickness dimension of the mounting surface part, when the front part is in close contact with the surface side of the liner, the surface of the mounting surface part and the surface of the front part can be made flush, improving the design.Furthermore, when the shoji screen is opened or closed to the outside or inside of the room relative to the fitting frame, a large clearance can be ensured between the lock receiving part of the door frame and the door end frame, and interference between the door end frame and the lock receiving part of the door end frame can be prevented when the shoji screen is opened or closed. Furthermore, by arranging the front component in the frame opening, movement of the front component in a first direction (for example, the up-down direction) can be restricted. Since the dimension of the front part in the second direction is larger than the dimension of the mounting surface in the second direction, the mounting surface can be covered by the front part when the position of the front part is adjusted in the second direction, which prevents the frame opening formed in the mounting surface from being exposed and improves the design.

[0038] In the building fixture of the present invention, it is preferable that the liner has an opening whose width and length dimensions are larger than those of the lock hole, a first long hole formed continuous with the opening in the first direction, and a second long hole formed on the opposite side of the opening to the first long hole, and that the back panel component is configured to be insertable into the opening of the liner. According to the fitting of the present invention, with the front part and the back plate part fastened with one fastening part, the back plate part can be inserted through the opening of the liner, and with the fastening part positioned on the back side of the liner, the opening can be moved to the first long hole. Therefore, the back plate part can be easily positioned on the back side of the liner, improving the assembly workability of the lock receiving part. [Explanation of symbols]
