The meeting stile of the inner shoji screen 20B (hereinafter referred to as the inner meeting stile 24B) is provided by adding an outer smoke deflector 20d to the frame body 20a, which is the same as the upper frame 22. The outer smoke deflector 20d extends outward from the outer edge on the outer circumference of the frame body 20a, and then extends inward. The meeting stile of the outer shoji screen 20A (hereinafter referred to as the outer meeting stile 24A) is provided by adding an inner hollow section 20e and an inner smoke deflector 20f to the frame body 20a, which is the same as the upper frame 22. The inner hollow section 20e is a hollow rectangular section located on the indoor side of the frame body 20a. The inner smoke deflector 20f extends in the visible direction from the inner edge of the inner hollow section 20e on the indoor side toward the inner circumference. The dimensions of the inner hollow section 20e and the inner smoke deflector 20f are set so that when the outer sash 20A and the inner sash 20B are positioned in the closed position, the inner smoke deflector 20f is positioned between the frame body 20a of the inner meeting frame 24B and the outer smoke deflector 20d. The lower frame 23 and the door edge frame 25 are constructed to have the same cross-sectional shape as the upper frame 22, with the addition of an indoor cover wall section 20g and an outdoor cover wall section 20h to the frame body 20a. The indoor cover wall portion 20g extends from the edge located on the indoor side of the frame body portion 20a toward the outer periphery. The outdoor cover wall portion 20h extends from the edge located on the outdoor side of the frame body portion 20a toward the outer periphery.The extended dimensions of the interior cover wall portion 20g and the exterior cover wall portion 20h are equal to each other. These upper frame 22, interior meeting frame 24B, exterior meeting frame 24A, lower frame 23, and door edge frame 25 are welded to each other via 45° joint surfaces formed at the ends of the individual frame body portions 20a to constitute the outer sash 20A and the interior sash 20B.

[0015] As described above, opening limiting devices are provided between the frame 10 and the outer sash 20A and inner sash 20B. The opening limiting devices restrict the opening width of the sashes 20 relative to the frame 10 and consist of an engaging receiving member 30 provided on the upper frame 11 and an engaging unit 40 provided on the door frame 25 of the sash 20.

[0016] As shown in Figure 6, the engaging receiving member 30 has an engaging projection 32 at one end of the mounting plate portion 31 and is provided on the inner circumference side of the frame body portion 10a between the outer visible wall portion 10c and the intermediate visible wall portion 10e, and between the inner visible wall portion 10d and the intermediate visible wall portion 10e. The mounting plate portion 31 is flat and is formed with a width that allows it to be positioned between the outer visible wall portion 10c and the intermediate visible wall portion 10e, and between the inner visible wall portion 10d and the intermediate visible wall portion 10e. Screw insertion holes 31a are arranged side by side in the depth direction of the mounting plate portion 31. The engaging projection 32 is hollow and protrudes downward from the end of the mounting plate portion 31 located on the door edge side, and has a receiving-side inclined contact surface 32a and a receiving-side engaging contact surface 32b. The receiving-side inclined contact surface 32a is inclined so as to gradually move towards the door edge from the outer edge of the mounting plate portion 31 towards the inner edge. The receiving-side engaging contact surface 32b extends vertically from the protruding edge of the receiving-side inclined contact surface 32a. The protruding dimension of the engaging projection 32 is set to ensure a gap between it and the upper frame 22 of the sliding door 20.

[0017] The engaging receiving member 30 is attached to the upper frame 11 via a backing plate 33. The backing plate 33 has an insertion plate portion 33a and two clamping backing plate portions 33b. The insertion plate portion 33a is configured as a flat plate that can be inserted into the hollow interior of the engaging projection 32. The two clamping backing plate portions 33b protrude from both side edges of the insertion plate portion 33a and then extend in a perpendicular direction. Each clamping backing plate portion 33b is formed to ensure a gap between it and the mounting plate portion 31 when the insertion plate portion 33a is inserted into the hollow interior of the engaging projection 32. Screw holes 33c are provided in the clamping backing plate portion 33b in the portion corresponding to the screw insertion hole 31a of the mounting plate portion 31.

[0018] To attach the engagement receiving member 30 to the upper frame 11 via the backing plate 33, four through holes 15 are formed on the inner circumference side of the frame body portion 10a, as shown in Figure 7. The four through holes 15 are arranged in parallel in the longitudinal and depth directions of the upper frame 11. The spacing between the through holes 15 arranged in parallel along the longitudinal direction of the upper frame 11 is set to be the same distance as the distance from the mounting plate portion 31 to the screw hole 33c. The spacing between the through holes 15 arranged in parallel along the depth direction is set to a distance that allows for the insertion of two clamping backing plate portions 33b. For these through holes 15, the clamping backing plate portions 33b are inserted into the two through holes 15 arranged on the door edge side, and then the orientation of the clamping backing plate portions 33b is changed so that they align with the longitudinal direction of the upper frame 11, thereby aligning the screw holes 33c of the clamping backing plate portions 33b with the remaining through holes 15. From this state, the insertion plate portion 33a is inserted into the hollow interior of the engaging projection 32, and the screw members 34 are screwed into the respective screw holes 33c via the screw insertion holes 31a and through holes 15 of the mounting plate portion 31, thereby enabling the engaging receiving member 30 to be attached to the upper frame 11. The position in which the engaging receiving member 30 is provided is a position in which the receiving side engaging contact surface 32b coincides with the opening restriction position of the sliding door 20. The opening restriction position of the sliding door 20 is set on the same vertical plane as the outer peripheral surface of the frame body portion 20a on the door frame 25 when the sliding door 20 is positioned at a position that limits the opening width relative to the frame body 10.

[0019] The engagement unit 40 is capable of contacting the engagement projection 32 of the engagement receiving member 30, and as shown in Figures 8 to 10, it comprises an inner case 41, an outer case 42, a latch hook (engagement member) 43, a slider 44, a pull handle member (operating member) 45, and a cover member 46.

[0020] The inner case 41 and outer case 42 are each made of a metal such as stainless steel. The inner case 41 has an inner base plate portion 41a and an inner connecting plate portion 41b. The inner base plate portion 41a is a flat plate that extends vertically. The inner connecting plate portion 41b extends from the upper edge of the inner base plate portion 41a in a direction perpendicular to it. Screw insertion holes 41c and 41d are provided in the inner base plate portion 41a and the inner connecting plate portion 41b, respectively. This inner case 41 is sized to be positioned between the indoor cover wall portion 20g and the outdoor cover wall portion 20h of the door frame 25.

[0021] The outer case 42 has an outer base plate portion 42a, a spring support plate portion 42b, a housing plate portion 42c, two housing side plate portions 42d, an outer connecting plate portion 42e, and two connecting side plate portions 42f. The outer base plate portion 42a is a flat plate that extends vertically. The extended dimension of the outer base plate portion 42a is shorter than that of the inner base plate portion 41a. A screw insertion hole 42g is provided at the lower end of the outer base plate portion 42a in a portion corresponding to the screw insertion hole 41c of the inner base plate portion 41a. The spring support plate portion 42b extends perpendicularly from the upper edge of the outer base plate portion 42a. The housing plate portion 42c extends upward from the extended edge of the spring support plate portion 42b. The extended dimension of the housing plate portion 42c is approximately the same as the extended dimension of the spring support plate portion 42b, and is formed to be smaller than the dimension along the visible direction of the interior cover wall portion 20g provided on the door frame 25. The two housing side plate portions 42d extend from both side edges of the housing plate portion 42c in a direction approaching the outer base plate portion 42a, so as to be approximately parallel to each other. The outer connecting plate portion 42e extends from the upper edge of the housing plate portion 42c in a direction approximately perpendicular to the direction opposite to the spring support plate portion 42b. The extended dimension of the outer connecting plate portion 42e is set to be larger than that of the spring support plate portion 42b, and the extended edge reaches a position beyond the outer base plate portion 42a. In the illustrated example, when the inner substrate portion 41a of the inner case 41 is superimposed on the outer substrate portion 42a, the extended dimension of the outer connecting plate portion 42e is set to coincide with the extended edge of the inner connecting plate portion 41b. The outer connecting plate portion 42e is provided with a hook projection hole 42h and a screw insertion hole 42i. The hook projection hole 42h is provided in the portion opposite to the spring support plate portion 42b and has a roughly square shape. The screw insertion hole 42i is provided in the portion opposite to the screw insertion hole 41d of the inner connecting plate portion 41b when the inner substrate portion 41a of the inner case 41 is superimposed on the outer substrate portion 42a. The connecting side plate portion 42f extends from both side edges in the lower part of the outer substrate portion 42a, in the same direction as the spring support plate portion 42b, and is substantially parallel to it. Each connecting side plate portion 42f is provided with a cover engagement hole 42j.

[0022] The latch hook 43 is rod-shaped, with its upper end being insertable into the hook projection hole 42h and its lower end not being insertable into the hook projection hole 42h, and is die-cast from a metal such as an aluminum alloy. The upper end of the latch hook 43 is provided with a latch-side engagement contact surface 43a and a latch-side inclined contact surface 43b. The latch-side engagement contact surface 43a is a flat surface extending in the vertical direction. The latch-side inclined contact surface 43b is inclined upward so as to gradually approach the latch-side engagement contact surface 43a. The lower end of the latch hook 43 is provided with a fitting pin 43c on the side surface located on the extension of the latch-side inclined contact surface 43b, and two slider engagement protrusions 43d are provided on each side thereof. Furthermore, a spring guide pin 43e is provided projecting downward from the lower end surface of the latch hook 43.

[0023] The slider 44 has a slider base portion 44a with clamping plate portions 44b on both sides, and is made of a metal such as stainless steel. The slider base portion 44a is a flat plate with dimensions corresponding to the lower end of the latch hook 43. The slider base portion 44a is provided with a fitting hole 44c into which the fitting pin 43c of the latch hook 43 can be fitted. The width of the slider base portion 44a is formed to a size that allows it to be placed between the housing side plate portions 42d of the outer case 42. The clamping plate portions 44b extend from both side edges of the slider base portion 44a in the same direction and are substantially parallel to each other. Each clamping plate portion 44b is provided with a latch engagement hole 44d into which the slider engagement projection 43d of the latch hook 43 engages. As is clear from the figure, a pull handle connecting piece 44e extends downward from the lower edge of each clamping plate portion 44b. Each pull tab connecting piece 44e is provided with a pin insertion hole 44f at its lower end.

[0024] The slider 44 is connected to the lower end of the latch hook 43 by fitting a fitting pin 43c into a fitting hole 44c of the slider base plate portion 44a and engaging a slider engagement projection 43d into a latch engagement hole 44d. The latch hook 43 to which the slider 44 is connected is installed in the outer case 42 with its upper end inserted through a hook projection hole 42h of the outer connecting plate portion 42e, and a pressure spring (biasing member) 47 positioned between the lower end surface and the spring support plate portion 42b via a spring guide pin 43e. The pull tab connecting piece 44e of the slider 44 extends downward from the lower edge of the housing side plate portion 42d, and the pin insertion hole 44f is located between the spring support plate portion 42b and the connecting side plate portion 42f.

[0025] As described above, the latch hook 43, which is installed on the outer case 42, is in a state where its upper end moves upward from the outer connecting plate portion 42e due to the biasing force of the compression spring 47. The amount of movement of the latch hook 43 from the outer connecting plate portion 42e is set to be larger than the gap secured between the engaging projection 32 of the engaging receiving member 30 and the upper frame 22 of the sliding door 20. By pressing the latch hook 43 downward against the biasing force of the compression spring 47, it is possible to move the latch hook 43 downward together with the slider 44 relative to the outer case 42.

[0026] The pull handle member 45 is molded from resin and has a hook portion 45a at its upper end and a knob portion 45b at its lower end. The pull handle member 45 is connected to the slider 44 in such a state that it can rotate around the axis of the connecting pin 48 by engaging the hook portion 45a with the connecting pin 48 which is fitted into the pin insertion hole 44f of the pull handle connecting piece 44e, and together with the latch hook 43 it can move up and down relative to the outer case 42.

[0027] The cover member 46 is molded from resin and has a cover base 46a and two cover side plates 46b. The cover base 46a covers the connection between the housing plate portion 42c and the spring support plate portion 42b of the outer case 42 and is flat in shape. A notch 46c is provided at the lower end of the cover base 46a for positioning the pull handle member 45. The cover side plates 46b extend from both side edges of the cover base 46a in the same direction and are substantially parallel. Outer connecting pieces 46d extend downward from the lower edges of the cover side plates 46b. Each outer connecting piece 46d is provided with a case engaging projection 46e that engages with a cover engaging hole 42j provided in the connecting side plate portion 42f. This cover member 46 is connected to the outer case 42 via the connecting side plate portion 42f by engaging the case engaging projections 46e with the cover engaging holes 42j.

[0028] As shown in Figures 9 to 11, the engagement unit 40 described above holds the inner base plate portion 41a of the inner case 41 superimposed on the outer base plate portion 42a of the outer case 42, and the inner connecting plate portion 41b superimposed on the outer connecting plate portion 42e. Then, while maintaining this state, the inner connecting plate portion 41b is superimposed on the outer peripheral surface of the upper frame 22, and the inner base plate portion 41a is positioned between the indoor cover wall portion 20g and the outdoor cover wall portion 20h of the door frame 25 and superimposed on the outer peripheral surface. From this state, the screw member 49 is screwed into the turn nut 50 of the upper frame 22 via the screw insertion hole 42i of the outer connecting plate portion 42e and the screw insertion hole 41d of the inner connecting plate portion 41b, and the screw member 49 is screwed into the turn nut 50 of the door frame 25 via the screw insertion hole 42g of the outer base plate portion 42a and the screw insertion hole 41c of the inner base plate portion 41a, thereby attaching it to the shoji screen 20. When screwing the screw member 49 into the turn nut 50 of the door frame 25 via the screw insertion hole 42g of the outer base plate portion 42a and the screw insertion hole 41c of the inner base plate portion 41a, this can be easily done by temporarily rotating the pull handle member 45, as shown in Figure 10.

[0029] In the engagement unit 40 attached to the sliding door 20, as shown in Figures 11(a), 12(a), and 13, the biasing force of the pressing spring 47 maintains the latch hook 43 in an extended position (engaged position) from the outer peripheral surface of the upper frame 22. As described above, the extension distance of the latch hook 43 is set to be larger than the gap secured between the engagement projection 32 of the engagement receiving member 30 and the upper frame 22 of the sliding door 20. Therefore, when the sliding door 20 is slid from the closed position toward the open position, as shown in Figures 14 and 15, the latch hook 43 comes into contact with the receiving-side engagement contact surface 32b of the engagement receiving member 30 via the latch-side engagement contact surface 43a. As a result, the opening width of the sliding door 20 relative to the frame 10 is limited, and it cannot be slid to the fully open position. Furthermore, even when the shoji screen 20 is open, the engaging unit 40 is positioned within an area that overlaps with the interior cover wall portion 20g and the exterior cover wall portion 20h in the depth direction, making it difficult to see from both the interior and exterior sides, thus avoiding any risk of impairing the appearance quality of the joinery. In addition to being difficult to see, the engaging unit 40 is positioned at the upper end of the shoji screen 20, so it is not within reach of children, and there is no concern about damage caused by mischief.

[0030] As described above, even when the opening width is limited, by inserting fingers between the indoor cover wall portion 20g and the outdoor cover wall portion 20h and operating the pull handle member 45 downward via the knob portion 45b, it is possible to move the latch hook 43 downward against the biasing force of the pressing spring 47, as shown in Figures 11(b), 12(b), and 16, and release the contact between the latch hook 43 and the engagement receiving member 30 (disengaged position). Therefore, by sliding the shoji screen 20 toward the open position from this state, the shoji screen 20 can be opened to the fully open position, as shown in Figure 17.

[0031] After the sliding door 20 has been opened to a position where the latch hook 43 has moved beyond the engaging receiving member 30, when the operating force applied to the pull handle member 45 is removed, the latch hook 43 is maintained in an upward-extended position again due to the biasing force of the pressing spring 47. Therefore, when the sliding door 20 is slid towards the closed position from this state, as shown in Figure 18, the latch hook 43 comes into contact with the receiving-side inclined contact surface 32a of the engaging receiving member 30 via the latch-side inclined contact surface 43b. When the sliding door 20 is slid further towards the closed position with the latch hook 43 in contact with the engaging receiving member 30 via the latch-side inclined contact surface 43b and the receiving-side inclined contact surface 32a, the inclined action of the latch-side inclined contact surface 43b and the receiving-side inclined contact surface 32a causes the latch hook 43 to move downward against the biasing force of the pressing spring 47, and eventually the contact between the latch-side inclined contact surface 43b and the receiving-side inclined contact surface 32a is released. This makes it possible to slide the sliding door 20 to the closed position without any operation on the engagement unit 40. When the sliding door 20 slides toward the closed position to a position where the latch hook 43 has passed the engagement receiving member 30, the biasing force of the pressing spring 47 maintains the latch hook 43 in an upward position again. Therefore, if the sliding door 20 is slid toward the open position from this state, the latch hook 43 will again come into contact with the receiving engagement contact surface 32b of the engagement receiving member 30 via the latch-side engagement contact surface 43a, making it possible to limit the opening width of the sliding door 20 relative to the frame 10.

[0032] In the above-described embodiment, a sliding window is used as an example, but it may also be a single-sliding window, or a double-hung window where the sash slides up and down. Furthermore, although the frame material of the frame body and the frame material of the sash are shown as being made of resin, they do not necessarily have to be made of resin. In addition, although the example shows an engaging receiving member that is attached to the upper frame to engage with the latch hook, it is not necessarily limited to this, and for example, it is also possible to configure it so that an engaging hole is directly provided in the upper frame and the latch hook is engaged with it. Furthermore, since a pressure spring is provided on the latch hook to bias it to the engaged position, the operation of engaging the latch hook with the engaging receiving member is unnecessary, but it is not necessarily necessary to provide a biasing member such as a pressure spring. In the above-described embodiment, when a pressure spring is provided, inclined surfaces are provided on both the latch hook and the engaging receiving member, so that when the sash is slid toward the closed position, the latch hook is retracted by the action of the inclined surfaces, but it is not necessarily necessary to provide inclined surfaces. If inclined surfaces are provided, it is sufficient to have one of them.

[0033] Furthermore, the frame material is provided with an indoor cover wall and an outdoor cover wall, and the latch hook is provided at a position that overlaps these in the depth direction; however, the outdoor cover wall is not necessarily required. In addition, the frame material may be formed in a hollow shape, and the latch hook may be provided inside it.

[0034] As described above, the joinery according to the present invention comprises a frame and a sliding screen slidably mounted on the frame, wherein the frame material that forms the door edge of the sliding screen has an interior cover wall portion, and the portion of the frame material that is on the exterior side of the interior cover wall portion is provided with an engaging member that moves between an engaged position and an unengaged position relative to the frame material, and an operating member that moves the engaging member, which is positioned in the engaged position, to the unengaged position, and the frame material extending in the sliding direction of the sliding screen in the frame is provided with an engaging receiving member that allows the sliding screen to slide to the fully open position relative to the frame when the engaging member is positioned in the unengaged position, while engaging with the engaging member to limit the opening width of the sliding screen relative to the frame when the engaging member is positioned in the engaged position, and each of the engaging member and the operating member is disposed within an area that overlaps with the interior cover wall portion in the depth direction. According to this invention, by engaging an engaging member provided on the frame material with an engaging receiving member provided on the frame material, it is possible to limit the opening width of the sliding door relative to the frame. Moreover, since the engaging member and the operating member for operating it are arranged in an area of ​​the frame material that overlaps with the interior side cover wall, it becomes difficult to see them from the interior side, thus preventing damage due to vandalism or compromising the appearance quality.

[0035] Furthermore, the present invention is characterized in that, in the above-described joinery, the frame material has an outdoor cover wall portion at a position opposite to the indoor cover wall portion, and the engaging member and the operating member are each disposed within an area that overlaps with the indoor cover wall portion and the outdoor cover wall portion in the depth direction. According to this invention, since the engaging member and the operating member are each disposed within an overlapping area of ​​the indoor and outdoor cover walls, it becomes difficult to see them from the outside, further reducing the risk of damage due to vandalism or deterioration of the appearance quality.

[0036] Furthermore, the present invention is characterized in that, in the above-described joinery, the shoji screen is arranged to slide left and right relative to the frame, and the engaging receiving member is provided on the inner circumferential surface of the upper frame constituting the frame. According to this invention, since the engagement receiving member is provided on the upper frame, the engagement member and the operating member are positioned high up on the vertical frame, eliminating the risk of them being tampered with by children.

[0037] Furthermore, the present invention is characterized in that the above-described joinery includes a biasing member that constantly biases the engaging member toward the engagement position relative to the frame material. According to this invention, since the engaging member is constantly biased toward the engaging position by the biasing member, there is no risk of forgetting to position the engaging member in the engaging position.

[0038] Furthermore, the present invention is characterized in that, in the above-described joinery, the engaging receiving member and at least one of the engaging members are provided with an inclined contact surface that gradually becomes toward the door edge side toward the inner circumference, and when the sliding door that has been opened beyond the engaging receiving member is slid toward the closed position, the engaging member and the engaging receiving member positioned at the engaging position come into contact with each other via the inclined contact surface. According to this invention, when a sliding door that has been opened beyond the engagement receiving member is slid toward the closed position, the inclination action of the inclined contact surface causes the engagement member to move toward the disengaged position against the biasing force of the biasing member, making it possible to slide the sliding door to the closed position without manipulating the engagement member. Moreover, if the sliding door slides beyond the engagement receiving member, the biasing member returns the engagement member to the engaged position, so even when the sliding door is slid toward the open position again, the opening width can be reliably limited.

[0039] Furthermore, in the above-described joinery, the present invention is characterized in that the engaging member is rod-shaped and is positioned at the engaged position and the disengaged position by reciprocating along the extending direction of the frame material. According to this invention, since the movement of the engaging member is a reciprocating movement along a straight line, the structure can be simplified.

[0040] Furthermore, the joinery according to the present invention comprises a frame and two sliding doors provided to slide left and right relative to the frame, wherein each vertical frame that forms the door edge of the sliding doors has an indoor cover wall portion and an outdoor cover wall portion that project toward the vertical frame constituting the frame, and in the portion of the vertical frame between the indoor cover wall portion and the outdoor cover wall portion, there is an engaging member that moves between an engaged position and an unengaged position by moving along the extending direction of the vertical frame, a biasing member that constantly biases the engaging member to the engaged position, and an operating member that moves the engaging member to the unengaged position against the biasing force of the biasing member, and the inner circumferential surface of the upper frame constituting the frame has a front relative to the frame when the engaging member is positioned in the unengaged position The sliding door is provided with an engagement receiving member that allows the sliding door to slide to its fully open position, while limiting the opening width of the sliding door relative to the frame by engaging with the engagement member via an engagement contact surface when the engagement member is positioned at the engagement position. The engagement receiving member and the engagement member are each provided with an inclined contact surface that gradually becomes the door edge side toward the inner circumference. When the sliding door that has been opened beyond the engagement receiving member is slid toward the closed position, the engagement member and the engagement receiving member positioned at the engagement position come into contact with each other via the inclined contact surfaces. The engagement member and the operating member are each disposed within an area that overlaps with the interior cover wall and the exterior cover wall in the depth direction.

[0041] According to this invention, by engaging an engaging member provided on the frame material with an engaging receiving member provided on the frame material, it is possible to limit the opening width of the sliding door relative to the frame. Moreover, since the engaging member and the operating member are each located in an area that overlaps with the indoor and outdoor cover wall portions, it becomes difficult to see them from the outside, thus preventing damage from vandalism or compromising the appearance quality. In addition, since the engaging receiving member is provided on the upper frame, the engaging member and the operating member are located high up on the vertical frame, eliminating the risk of children tampering with them. Furthermore, when a sliding door that has been opened beyond the engaging receiving member is slid toward the closed position, the inclined action of the inclined contact surface causes the engaging member to move to the unengaged position against the biasing force of the biasing member, making it possible to slide the sliding door to the closed position without operating the engaging member. Moreover, when the sliding door slides beyond the engaging receiving member, the biasing member returns the engaging member to the engaged position, so even when the sliding door is slid toward the open position again, the opening width can be reliably limited.
