[0011] Hereinafter, embodiments of the present invention will be described based on the drawings. The descriptions of the embodiments of the inventions according to claims 1, 2, and 3 are mainly described in paragraphs

[0013] ,

[0018] ,

[0019] , and

[0021] . Figs. 1 to 7 show a first embodiment of a fitting of the present invention. This fitting opens and closes an opening between rooms in a building or an opening between a corridor and a room with a single sliding door. As shown in Figs. 1 to 3, this fitting includes a rail 22 attached to the upper part of the opening 21, a sliding door 13 suspended and supported by the rail 22 via suspension wheels 14, 14, and a restraining component 12 installed on the floor surface 23.

[0012] As shown in Fig. 3, the rail 22 is formed in a groove shape with a substantially C-shaped cross-section that is open at the bottom, made of an aluminum alloy extrusion profile. The suspension wheels 14 are held on the rail 22 so as to be movable in the longitudinal direction of the rail 22. The rail 22 is attached to the upper edge 21a of the opening 21 by screwing from below with screws (not shown).

[0013] As shown in Figs. 1 to 3, the sliding door 13 is formed by assembling an upper frame 6, a lower frame 7, and vertical frames 1a, 1b on the leading and trailing sides of the door into a rectangle using aluminum alloy extrusion profiles, and fitting a panel 2 made of resin or glass inside. Further, the sliding door 13 has vertical and horizontal grids 8, 9 provided in a cross shape on the inner peripheral side of the four surrounding frames 1a, 1b, 6, 7. The vertical and horizontal grids 8, 9 are provided on both one side and the other side in the expected direction of the panel 2 as shown in Figs. 2 and 3.

[0014] As shown in Fig. 3, the upper frame 6 has a panel-engaging groove 3 with an open inner peripheral side. A hard gasket 5 is fitted and attached to the panel-engaging groove 3, and the upper edge portion of the panel 2 is held in the panel-engaging groove 3 via the hard gasket 5. The groove bottom wall 4 of the panel-engaging groove 3 is formed in a shape where the central portion in the expected direction is recessed toward the outer peripheral side, and the hard gasket 5 is inserted into the recess 24. Tapping holes 25 are formed on one side and the other side in the expected direction of the recess 24 of the groove bottom wall 4 of the panel-engaging groove 3. Furthermore, the upper frame 6 has a recessed wall 26 on its outer circumference, and a hollow section 27 is formed on the inner circumference of the recessed wall 26.

[0015] As shown in Figure 3, the lower frame 7, like the upper frame 6, has a panel-fitting groove 3 with an open inner circumference. A rigid glazing channel 5 is fitted into the panel-fitting groove 3 and attached, and the lower edge of the panel 2 is held in the panel-fitting groove 3 via the rigid glazing channel 5. Furthermore, the lower frame 7 has a groove 28 at its lower end with a roughly C-shaped cross-section that opens on its outer circumference. A resin rail 29 is held within this groove 28, and the guide pin (engaging part) 17 of the anti-sway component 12 engages with the groove 30 of the rail 29, thereby restricting the downward movement of the lower part of the sliding door 13.

[0016] As shown in Figure 2, the vertical frames 1a and 1b on the leading and trailing ends of the door have panel-receiving grooves 3 that are open on the inner circumference, similar to the upper and lower frames 6 and 7. A rigid glazing channel 5 is fitted into the panel-receiving groove 3, and the side edge of the panel 2 is held in the panel-receiving groove 3 via the rigid glazing channel 5. The bottom wall 4 of the panel-receiving groove 3 is formed in a shape that is recessed toward the outer circumference in the center in the depth direction, and the rigid glazing channel 5 is inserted into this recess 24. Furthermore, the vertical frames 1a and 1b do not have a recessed wall on the outer periphery side of the groove bottom wall 4 of the panel insertion groove 3, and a groove 31 is formed that is open on the outer periphery side, and this groove 31 is closed by attaching a cover plate 32. In this way, the central part of the groove bottom wall 4 of the panel insertion groove 3 is formed in a recessed shape toward the outer periphery, and the rigid glazing channel 5 is inserted into the recess 24, thereby minimizing the visible dimensions (width dimensions) of the vertical frames 1a and 1b. Specifically, the visible dimensions of the vertical frames 1a and 1b are set to 15 mm. The upper frame 6 and lower frame 7 also have a smaller visible dimension of 27mm.

[0017] As shown in Figure 5, resin caps 33 are attached to the lower ends of the vertical frames 1a and 1b. The caps 33 have a projection 34 that is inserted from below into the panel-receiving grooves 3 of the vertical frames 1a and 1b. The projection 34 has a guide pin receiving groove 35 with an open inner circumference, into which the guide pin 17 of the anti-sway component 12 is inserted and held when the sliding door 13 is fully open or fully closed. This groove is formed to be continuous with the groove 30 of the rail 29.

[0018] As shown in Figures 2 and 3, the vertical and horizontal grids 8 and 9 are formed in the shape of round bars from extruded aluminum alloy profiles, with tapping holes 36 formed in the longitudinal direction at the center. As shown in Figures 1, 2, and 4(a), the horizontal lattice 9 is attached across the vertical frames 1a and 1b by having its left and right end faces abut against the inner circumferential surfaces of the vertical frames 1a and 1b on the door-leading and door-looping sides, and by screwing screws 37, which are inserted from the side into the vertical frames 1a and 1b, into the tapping holes 36 of the horizontal lattice 9. As shown in Figures 1, 3, and 4(a), the vertical grid 8 is divided vertically at the point where it intersects with the horizontal grid 9, and is connected to the horizontal grid 9 by a grid connector 10. The lattice connector 10 is made of resin and, as shown in Figure 4(a), has cylindrical parts 38a and 38b into which horizontal lattices 9 and vertical lattices 8 can be inserted, intersecting in a cross shape vertically and horizontally. The horizontal lattice 9 is inserted through the horizontal cylindrical part 38a, and the ends of the vertical lattices 8, which are divided above and below the horizontal lattice 9, are inserted into the vertical cylindrical parts 38b from above and below, respectively.

[0019] The upper and lower ends of the vertical lattice 8 are attached to the upper frame 6 and lower frame 7, respectively, via frame mounting brackets 11, as shown in Figures 4(b) and 10. The frame mounting bracket 11 is made of resin and has four divided claw-shaped outer peripheral retaining parts 39 and a circular flange-shaped inner peripheral retaining part 40, with a hole 41 formed in the center into which the end of the vertical lattice 8 is inserted. As shown in Figure 10(a), the frame mounting bracket 11 is installed by inserting the outer peripheral retaining portion 39 from the inner peripheral side into the hole 43 formed in the inner peripheral wall 42 of the upper frame 6 and lower frame 7. Then, as shown in Figure 10(b), the outer peripheral retaining portion 39 engages with the outer peripheral side of the hole 43, and the inner peripheral retaining portion 40 engages with the inner peripheral side of the hole 43, thereby preventing the frame mounting bracket 11 from coming out of the hole 43. Then, as shown in Figures 10(b) and (c), when the ends of the vertical bars 8 are inserted into the holes 41 of the frame mounting fixture 11 from the inner circumference side, the ends of the vertical bars 8 are attached to the upper frame 6 and lower frame 7 via the frame mounting fixture 11.

[0020] Next, the assembly procedure for the sliding door 13 will be explained. First, as shown in Figure 8, the rigid glazing channel 5 is fitted into the panel-fitting grooves 3 of the upper frame 6, lower frame 7, and vertical frames 1a and 1b from the inner circumference side. Next, as shown in Figure 9-1(a), one end face of the upper frame 6 is brought into contact with the inner circumferential surface of one of the vertical frames 1a, and the screw 44, which has been inserted through the vertical frame 1a from the outer circumferential side, is screwed into the tapping hole 25 (see Figure 3) of the upper frame 6 to connect the upper frame 6 and the vertical frame 1a. Next, as shown in Figure 9-1(b), the panel 2 is inserted from the inner perimeter into the rigid glazing channel 5 of the upper frame 6 and vertical frame 1a, which are connected in an L-shape. Next, as shown in Figure 9-2(c), the other vertical frame 1b is attached from the outer periphery while inserting the panel 2 into the rigid glazing channel 5, and the screws 44 that were inserted through the vertical frame 1b from the outer periphery are screwed into the tapping holes 25 of the upper frame 6 to connect the upper frame 6 and the vertical frame 1b. Subsequently, as shown in Figure 9-2(d), the lower frame 7 is attached from the outer periphery while inserting the panel 2 into the rigid glazing channel 5, and screws 44 inserted from the outer periphery into the vertical frames 1a and 1b are screwed into the tapping holes 25 of the lower frame 7 to connect the lower frame 7 and the vertical frames 1a and 1b.

[0021] Next, as shown in Figure 9-3(e), the horizontal lattice 9 is passed through the lattice connector 10, and both ends of the horizontal lattice 9 are brought into contact with the inner circumferential surfaces of the vertical frames 1a and 1b. Screws 37, which have been inserted through the vertical frames 1a and 1b from the outer circumferential side, are then screwed into the tapping holes 36 (see Figure 3) of the horizontal lattice 9 to install the horizontal lattice 9 between the vertical frames 1a and 1b. In addition, frame mounting fixtures 11 are attached to the holes 43 of the upper frame 6 and lower frame 7 from the inner circumferential side (see Figure 10). Next, as shown in Figure 9-3(f), the lowest of the three divided vertical bars 8 is attached between the lower horizontal bar 9 and the lower frame 7. When attaching this vertical bar 8, the lower horizontal bar 9 is bent upward, the upper end of the vertical bar 8 is inserted into the cylindrical part 38b of the bar connector 10, and the lower end of the vertical bar 8 is inserted from the inner side into the hole 41 of the frame mounting fixture 11 attached to the lower frame 7. Next, as shown in Figure 9-4(g), the middle vertical lattice 8 of the three divided sections is attached between the horizontal lattices 9, 9. When attaching this vertical lattice 8, the upper horizontal lattice 9 is bent upward, the upper end of the vertical lattice 8 is inserted into the cylindrical part 38b of the lattice connector 10, and the lower end of the vertical lattice 8 is inserted into the cylindrical part 38b of the lattice connector 10 attached to the lower horizontal lattice 9. Next, as shown in Figure 9-4(h), the uppermost of the three divided vertical bars 8 is attached between the upper frame 6 and the upper horizontal bar 9. When attaching this vertical bar 8, the upper horizontal bar 9 is bent downwards, the lower end of the vertical bar 8 is inserted into the cylindrical part 38b of the bar connector 10, and the upper end of the vertical bar 8 is inserted from the inner side into the hole 41 of the frame mounting fixture 11 attached to the upper frame 6. Next, the fascia boards 32 are attached to the outer perimeter of the vertical frames 1a and 1b.

[0022] In this way, the sliding door 13 of this joinery can be easily assembled by fitting the rigid glazing channel 5 into the panel-receiving grooves 3 of the upper frame 6, lower frame 7, and vertical frames 1a, 1b, and then sequentially connecting the frames 1a, 1b, 6, and 7 while inserting the edges of the panel 2 into the rigid glazing channel 5. Furthermore, the vertical and horizontal grids 8 and 9 only require cutting round rods to a predetermined length, and after assembling the four perimeter frames 1a, 1b, 6, and 7, the vertical and horizontal grids 8 and 9 can be easily attached to the inner sides of the four perimeter frames 1a, 1b, 6, and 7 via the grid connectors 10 and frame mounting fixtures 11, resulting in good assembly efficiency.

[0023] As shown in Figures 1 and 6, the suspension rollers 14 are attached to both the left and right ends of the upper frame 6. As shown in Figures 3, 6, and 7, the suspension roller 14 has a suspension roller body 46 equipped with wheels 45 that engage with the rail 22 and rotate, and a mounting shaft 15 (height adjustment mechanism) suspended from the suspension roller body 46, with a mounting part 20 attached to the upper frame 6 at the lower part of the mounting shaft 15. The mounting part 20 has a hexagonal head 47 provided at the lower end of the mounting shaft 15, and a circular flange 48 provided above the hexagonal head 47 with a gap equal to the thickness of the recessed wall 26 of the upper frame 6. The mounting shaft 15 has a male screw 49 formed on its outer circumference, and by placing a tool on the hexagonal head 47 and rotating it, the length of the protrusion from the suspension roller body 46 changes, and the height of the sliding door 13 can be adjusted accordingly.

[0024] As shown in Figures 6 and 7, notches 19 are formed at both the left and right ends of the projection wall 26 of the upper frame 6, with the outer circumference in the longitudinal direction of the upper frame 6 being open. The suspension pulley 14 is attached to the upper frame 6 by inserting the mounting portion 20 provided at the lower part of the mounting shaft 15 into the notches 19 from the outer circumference in the longitudinal direction of the upper frame 6. Fixing parts 18 are attached to the upper ends of the left and right vertical frames 1a and 1b to hold the mounting part 20 of the suspension wheel 14 in place so that it does not come out of the notch 19 of the upper frame 6. The fixing part 18 is made of resin and also serves as a cap to conceal the notch 50 (see Figure 7) formed at the upper end of the vertical frames 1a, 1b for inserting the mounting portion 20 of the suspension wheel 14. It has a plate-like portion 51 that is flush with the cover plate 32, and a support portion 52 and a claw piece 53 that protrude inward from the plate-like portion 51 and are inserted into the inner side of the inner wall 26 of the upper frame 6. The support portion 52 has an engaging portion 54 at its tip that engages with the hexagonal head 47 of the mounting portion 20 of the suspension wheel 14. The claw piece 53 has a locking portion 56 at its tip that engages with a square hole 55 formed in the inner wall 26 of the upper frame 6. As shown in Figure 7, the fixing component 18 is attached by first inserting the mounting portion 20 of the suspension wheel 14 into the notch 19 of the inner wall 26 of the upper frame 6 from the outer circumference in the longitudinal direction of the upper frame 6, and then inserting the support portion 52 and claw piece 53 into the inner circumference of the inner wall 26 of the upper frame 6 from the outer circumference in the longitudinal direction of the upper frame 6. Once the fixing component 18 is attached in this way, as shown in Figure 6, the hexagonal head 47 of the mounting portion 20 of the suspension wheel 14 engages with the engaging portion 54 provided at the tip of the support portion 52 of the fixing component 18, and the locking portion 56 provided at the tip of the claw piece 53 engages with the square hole 55 provided in the inner wall 26 of the upper frame 6, thereby preventing the fixing component 18 from coming off, and thus the mounting portion 20 of the suspension wheel 14 is fixed to the notch 19 of the upper frame 6.

[0025] As shown in Figures 2, 3, and 5, the anti-vibration component 12 has a base portion 16 fixed to the floor surface 23 and a guide pin (engaging portion) 17 that protrudes upward from the base portion 16. As shown in Figures 2 and 5, the base portion 16 is formed in a long, plate-like shape in the left-right direction, and has mounting portions 57, 57 at both left and right ends that are attached to the floor surface 23, with the intermediate portion between the mounting portions 57, 57 being raised above the floor surface 23. The mounting portions 57, 57 have elongated holes 58 formed along the depth direction, and the base portion 16 is fixed to the floor surface 23 with screws 59 inserted into the elongated holes 58 from above. An elongated hole 60 is formed in the intermediate portion of the base portion 16 along the opening and closing direction (left-right direction) of the sliding door 13. As shown in Figure 5, the guide pin 17 has its lower end attached to the elongated hole 60 in the middle of the base portion 16, and is movable in the opening and closing direction of the sliding door 13.

[0026] Next, I will explain how to hang the sliding door 13. First, before hanging the sliding door 13, attach the suspension rollers 14, 14 to the rail 22. Then, the sliding door 13 is held at an angle in the forward direction, the guide pin 17 of the anti-sway component 12 is inserted into the groove 30 of the rail 29 attached to the lower end of the sliding door 13, and then the sliding door 13 is raised vertically. Next, as shown in Figure 7, the suspension wheel 14 is slid along the rail, and the mounting portion 20 of the suspension wheel 14 is inserted into the notch 19 of the recessed wall 26 of the upper frame 6 from the outer peripheral side in the longitudinal direction of the upper frame 6. Subsequently, as shown in Figure 7, the fixing parts 18 are attached to the upper ends of the vertical frames 1a and 1b from the outer circumference in the longitudinal direction of the upper frame 6, thereby fixing the suspension rollers 14 to the upper frame 6.

[0027] Figure 17 shows an example of a conventional suspension pulley 90. In the conventional suspension pulley 90, a metal fitting 92 made of a bent metal is provided at the lower end of the mounting shaft 91, and this fitting 92 is attached to the inner wall 26 of the upper frame 6 by screwing it with screws 93 from the outer circumference. In this structure, the fittings 92 of the suspension wheel 90 must be screwed to the outer wall 26 of the upper frame 6, so the sliding door 13 cannot be hung from the in-plane direction on the rail 22 attached to the opening 21 afterwards, resulting in poor workability. In contrast, as mentioned earlier, the sliding door 13 of this joinery is constructed by inserting the mounting portion 20 of the suspension wheel 14 into the notch 19 of the recessed wall 26 of the upper frame 6 from the outer circumference in the longitudinal direction of the upper frame 6, and then inserting it into the inner circumference of the recessed wall 26 of the upper frame 6 and attaching the fixing part 18 to fix the mounting portion 20 of the suspension wheel 14, thereby making it easy to hang the sliding door 13 from the in-plane direction. Furthermore, by not using metal fittings 92 made of bent material like the conventional suspension wheel 90, the visible dimensions of the upper frame 6 can be reduced.

[0028] Figure 11 shows the case where the column 61 forming the opening 21 is slightly inclined in the in-plane direction (the upper part of the column is tilted to the left). When the column 61 is tilted in this way, a gap 63 is created between the column 61 and the lower side of the door edge 62 of the sliding door 13, as shown in Figure 11(a). In such cases, as shown in Figure 11(b), the mounting shaft 15 of the hanging roller 14 on the door edge side is rotated with a tool, lowering the door edge side of the sliding door 13. As a result, the lower part of the door edge side of the sliding door 13 moves towards the door edge side, and the guide pin 17 also moves towards the door edge side accordingly. This eliminates the gap 63 between the door edge 62 of the sliding door 13 and the lower post 61, allowing the sliding door 13 to be closed properly. In this manner, by rotating the mounting shaft 15 of the suspension wheel 14 to adjust the position of the sliding door 13, the guide pin 17 moves in accordance with the movement of the sliding door 13, so that the sliding door 13 can be properly closed without creating a gap 63 between the door edge 62 of the sliding door 13 and the column 61. Furthermore, if the guide pin 17 is fixed in the position shown in Figure 11(a), even if the mounting shaft 15 of the hanging roller 14 on the door-end side is extended, the movement of the lower part of the door-end side of the sliding door 13 is restricted by the guide pin 17, making it impossible to eliminate the gap 63 between it and the column 61.

[0029] Figure 12 is a cross-sectional view of the door, with Figure 12(a) showing the fully open state and Figure 12(b) showing the fully closed state. Because the visible dimensions of the vertical frames 1a and 1b are very small at 15 mm, the range in which the guide pin 17 can move left and right within the visible dimensions of the vertical frames 1a and 1b is small. However, as shown in the figure, the position of the guide pin 17 moves in the opening and closing direction of the sliding door 13 in the fully open and fully closed states. As a result, in the fully open state shown in Figure 12(a), the leading edge 62 of the sliding door 13 is at the same position as the side edge 21b on the tail end side of the opening 21, and in the fully closed state shown in Figure 12(b), the inner circumferential surface 64 of the vertical frame 1b on the tail end side is at the same position as the side edge 21b on the tail end side of the opening 21, resulting in a good fit of the vertical frames 1a and 1b to the opening 21.

[0030] Figure 13 shows a comparative example of the door fitting of the present invention, in which the guide pin 17 is fixed to the floor. In this case, as shown in Figure 13(a), if the leading edge 62 of the sliding door 13 is in the same position as the side edge 21b on the tail end side of the opening 21 when fully open, then as shown in Figure 13(b), when fully closed, the inner circumferential surface 64 of the vertical frame 1b on the tail end side is shifted toward the tail end side relative to the side edge 21b on the tail end side of the opening 21, resulting in a poor fit of the vertical frames 1a and 1b relative to the opening 21.

[0031] Figures 14 and 15 show a second embodiment of the joinery of the present invention. This joinery opens and closes with two sliding doors: a one-sided sliding door 13a positioned on one side of the interior opening 21 in the depth direction, and a other-sided sliding door 13b positioned on the other side in the depth direction. The one-sided sliding door 13a and the other-sided sliding door 13b have the same structure as the sliding door 13 of the first embodiment, except that the vertical and horizontal grids 8 and 9 are not attached.

[0032] As shown in Figures 14 and 15, a magnetic guide pin 65 is embedded in the floor surface 23 along the line through which the sliding door 13a passes. This guide pin 65 protrudes from the floor surface 23 only when the sliding door 13a passes, and engages with a groove 30 in the rail 29 provided at the lower end of the sliding door 13a, thereby restricting the downward movement of the lower part of the sliding door 13a.

[0033] As shown in Figures 14 and 15, an interlocking component 66 is attached to the lower end of the vertical frame 1a on the leading edge side of one sliding door 13a, for interlocking both sliding doors 13a and 13b when opening and closing them. The interlocking component 66 has a plate-shaped base portion 16 fixed to the lower end of one sliding door 13a, and a guide pin 17 that protrudes upward from the base portion 16. The base portion 16 extends from below the vertical frame 1a on the leading edge side of one sliding door 13a to the other side, and extends to below the other sliding door 13b. Below the other sliding door 13b, the base portion 16 has an elongated hole 60 (see Figure 15) that is aligned with the opening and closing direction (left and right direction) of the other sliding door 13b. The guide pin 17 has its lower end attached to the elongated hole 60 of the base portion 16 and is movable in the opening and closing direction of the other sliding door 13b.

[0034] As shown in Figures 15(a) and (b), the guide pin 17 moves within the elongated hole 60 of the base portion 16 when the door is fully open and fully closed. As a result, in the fully open state shown in Figure 15(a), the leading edges 62 of one sliding door 13a and the other sliding door 13b are in the same position as the side edge 21b on the tail end side of the opening 21. In the fully closed state shown in Figure 15(b), the inner circumferential surface 64 of the vertical frame 1b on the tail end side of one sliding door 13a is in the same position as the side edge 21b on the tail end side of the opening 21. Furthermore, the vertical frame 1a on the leading edge side of one sliding door 13a and the vertical frame 1b on the tail end side of the other sliding door 13b perfectly overlap in the projection direction, resulting in a good fit of the vertical frames 1a and 1b to the opening 21.

[0035] Figure 16 shows a comparative example of the joinery of the present invention, in which the guide pin 17 is fixed to one side sliding door 13a. In this case, as shown in Figure 16(a), when fully open, the other side sliding door 13b is slightly offset towards the leading edge relative to the one side sliding door 13a, and the leading edge 62 of the other side sliding door 13b protrudes from the side edge 21b on the trailing edge side of the opening 21. As shown in Figure 16(b), when fully closed, the vertical frame 1a on the leading edge side of the one side sliding door 13a and the vertical frame 1b on the trailing edge side of the other side sliding door 13b are slightly offset laterally, resulting in a poor fit of the vertical frames 1a and 1b relative to the opening 21.

[0036] In the second embodiment, similar to the first embodiment, if the column 61 forming the opening 21 is slightly inclined in the in-plane direction, the mounting shaft 15 of the suspension wheel 14 of the other sliding door 13b is rotated to adjust the position of the other sliding door 13b. As a result, the guide pin 17 moves in accordance with the movement of the lower part of the other sliding door 13b, eliminating the gap 63 between the door edge 62 of the other sliding door 13b and the column 61, allowing the other sliding door 13b to be properly closed.

[0037] As described above, the joinery (first and second embodiments) comprises vertical frames 1a and 1b and a panel 2. The vertical frames 1a and 1b have panel-receiving grooves 3 on their inner circumference, and the groove bottom wall 4 of the panel-receiving groove 3 is formed in a shape where the central part in the depth direction is recessed toward the outer circumference. The panel 2 is held in the panel-receiving groove 3 via a glazing channel (hard glazing channel) 5 (see Figure 2), resulting in good assembly. Furthermore, because the groove bottom wall 4 of the panel-receiving groove 3 of the vertical frames 1a and 1b is formed in a shape where the central part in the depth direction is recessed toward the outer circumference, the visible dimensions of the vertical frames 1a and 1b can be reduced. This joinery further improves the ease of assembly of the sliding door 13 by inserting the panel 2 into the glazing channel 5 while the glazing channel 5 is fitted into the panel-receiving groove 3 of the frame (upper frame 6, lower frame 7, vertical frame 1a, 1b). In addition to the vertical frames 1a and 1b, the top frame 6 and bottom frame 7 also have the groove bottom wall 4 of the panel-receiving groove 3 formed in a shape where the center in the depth direction is recessed toward the outer periphery, which allows the visible dimensions of the top frame 6 and bottom frame 7 to be reduced.

[0038] This joinery (first embodiment) comprises frames 1a, 1b, 6, and 7 on all four sides, and vertical and horizontal grids 8 and 9 provided on the inner sides of the frames 1a, 1b, 6, and 7. The vertical and horizontal grids 8 and 9 are connected at their intersections by grid connectors 10. One grid 9 of the vertical and horizontal grids 8 and 9 is inserted through the grid connector 10, and the end of the other grid 8 is inserted into the grid connector 10 (see Figures 1 and 4). This allows the vertical and horizontal grids 8 and 9 to be easily assembled, resulting in good assembly efficiency. The grid connector 10 has cylindrical parts 38a and 38b into which grids 8 and 9 can be inserted, which intersect in a cross shape (see Figure 4), so that vertical and horizontal grids 8 and 9 can be easily connected by intersecting them. On the other hand, the lattice 9 is fixed to frames 1a and 1b at both ends in the longitudinal direction (see Figure 2), making installation easy. Since the other grid 8 is divided by the other grid 9 (see Figure 4(a)), there is no need to form a notch at the intersection, and it is only necessary to cut the end straight, making it easy to process. One of the grids, 9, is a long piece that spans between the frames 1a and 1b, while the other grid, 8, is divided by the first grid, 9 (see Figures 2, 3, and 4). Since both the first grid, 9, and the second grid, 8, only need to be cut to a predetermined length, costs can be reduced.

[0039] This joinery (first embodiment) comprises frames 1a, 1b, 6, and 7 on all four sides, and a lattice (vertical lattice) 8 provided on the inner side of the frames 1a, 1b, 6, and 7. The longitudinal ends of the lattice 8 are attached to the frames 6 and 7 via frame mounting fixtures 11 that engage with holes 43 in the frames 6 and 7 (see Figures 3, 4, and 10), making it easy to install the lattice 8 and improving ease of assembly. In this door and window (first embodiment), the frame mounting bracket 11 is attached by engaging it with the holes 43 in the frames 6 and 7, and the lattice 8 is attached to the frame mounting bracket 11 attached to the frames 6 and 7 from the inner circumference side using a sliding tab (see Figures 9-3 and 9-4), making it easy to attach the ends of the lattice 8 to the frames 6 and 7. The frame mounting bracket 11 has a retaining portion 39 that engages with the outer circumference of the holes 43 in the frames 6 and 7, and a retaining portion 40 that engages with the inner circumference of the holes 43 in the frames 6 and 7 (see Figure 10). Therefore, it can be easily attached to the holes 43 in the frames 6 and 7, further improving ease of assembly.

[0040] This joinery (first embodiment) comprises frames 1a, 1b, 6, and 7 on all four sides, and vertical and horizontal grids 8 and 9 provided on the inner sides of the frames 1a, 1b, 6, and 7. The vertical and horizontal grids 8 and 9 are connected at their intersections by grid connectors 10. One of the grids 9 is inserted through the grid connector 10, and the other grid 8 is attached to the frames 6 and 7 via a frame mounting bracket 11 that locks one end in the longitudinal direction into the grid connector 10 and the other end into a hole 43 in the frame 6 and 7 (see Figures 1 and 4). As a result, the vertical and horizontal grids 8 and 9 can be easily attached to the inner sides of the frames 1a, 1b, 6, and 7, and assembly is easy.

[0041] This door (first embodiment) comprises a sliding door 13 and a sway-preventing component 12. The sliding door 13 is suspended from above by a suspension wheel 14, and the suspension wheel 14 has a height adjustment mechanism (mounting shaft) 15 for the sliding door 13. The sway-preventing component 12 has a base portion 16 fixed to the floor surface 23 and an engaging portion (guide pin) 17 provided on the base portion 16 so as to be movable in the opening and closing direction of the sliding door 13. The engaging portion 17 engages with the lower end of the sliding door 13 to restrict the sway of the sliding door 13 in the forward direction (see Figures 2 and 3). As shown in Figure 11, when the height of the sliding door 13 is adjusted using the height adjustment mechanism 15 of the suspension wheel 14, the engaging portion 17 of the sway-preventing component 12 moves in accordance with the movement of the sliding door 13, allowing the sliding door 13 to be closed properly and providing good usability.

[0042] This door (second embodiment) comprises a sliding door 13a on one side, a sliding door 13b on the other side, and an interlocking component 66. Both sliding doors 13a and 13b are suspended and supported by a suspension roller 14, the suspension roller 14 has a height adjustment mechanism (mounting shaft) 15 for the sliding doors 13a and 13b, and the interlocking component 66 has a base portion 16 fixed to the lower end of the leading edge side of the sliding door 13a on one side, and an engaging component provided on the base portion 16 so as to be movable in the opening and closing direction of the sliding door 13b on the other side. The interlocking component 66 has a guide pin 17, and the engaging portion 17 engages with the lower end of the other sliding door 13b to restrict the forward movement of the other sliding door 13b (see Figures 14 and 15). Therefore, when the height of the other sliding door 13b is adjusted using the height adjustment mechanism of the suspension wheel 14, the engaging portion 17 of the interlocking component 66 moves in accordance with the movement of the other sliding door 13b, allowing the other sliding door 13b to be properly closed, resulting in a user-friendly design.

[0043] This door (first and second embodiments) comprises an upper frame 6, a suspension wheel 14, and a fixing part 18. The upper frame 6 has a notch 19 at the longitudinal end of the interior wall 26, with the longitudinal outer circumference of the upper frame 6 being open. The suspension wheel 14 has a mounting part 20 that attaches to the upper frame 6, and the mounting part 20 is inserted into the notch 19 of the upper frame 6 from the longitudinal outer circumference of the upper frame 6. The fixing part 18 is attached to the inner circumference of the interior wall 26 at the longitudinal end of the upper frame 6, and holds the mounting part 20 of the suspension wheel 14 so that it does not come out of the notch 19 of the upper frame 6 (see Figures 6 and 7). As a result, the sliding door 13 can be easily hung and is easy to use.

[0044] The present invention is not limited to the embodiments described above. The material and cross-sectional shape of the frame and lattice can be changed as appropriate. The shape and material of the lattice connector and frame mounting fixture can be changed as appropriate. The present invention is not limited to building fixtures installed indoors, but can also be applied to windows and the like that are installed facing outdoors. [Explanation of Symbols]
