Description

[Technical field]

[0001] The present invention relates to a fitting and a closure limiting device, and more specifically to a fitting in which a sliding screen is supported on a frame so that it can be tilted inward, and a closure limiting device applied thereto. [Background technology]

[0002] For fixtures in which a screen is arranged so that it can slide relative to a frame, such as sash windows and sliding windows, there are provided windows equipped with a closing limiting device to prevent fingers from becoming caught between the frame and the screen when the screen is placed in the closed position (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-303634 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in some fittings in which a sliding screen is arranged on a frame, the screen can be rotated around the leading edge of the screen so that the trailing edge protrudes into the room, and the screen can be placed in a tilted-in position relative to the frame. This type of fitting has the advantage that the surface of the screen facing the outside is exposed to the room, making cleaning easier. However, with this type of fitting, it is difficult to apply a closure limiting device because an external force is applied to the closure limiting device through the screen that moves to the tilted-in position, which may cause damage to the closure limiting device.

[0005] In view of the above-mentioned situation, the present invention aims to provide a fitting and a closure limiting device that can prevent fingers from becoming caught in a sliding door that can be moved into an inward tilting position relative to the frame. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the fittings of the present invention are fittings comprising a shoji screen that is slidable relative to a frame body and can be moved to an inward-tilted position with the door end side protruding toward the room from the center, and a close limiting device that is directly or indirectly attached to a structure that supports the frame body and limits the sliding of the shoji screen in the closing direction, wherein the close limiting device comprises a device main body that is directly or indirectly attached to the structure, and a stopper member that is movably supported relative to the device main body, and that moves forward and backward toward the outside of the room when the shoji screen is placed in the open position to prevent the shoji screen from sliding in the closing direction, and moves backward and toward the inside of the room when the shoji screen moves to the inward-tilted position. Effect of the Invention

[0007] According to the present invention, the stopper member is movably disposed relative to the device body, and the retractable movement eliminates the risk of damage caused by external force from the sliding screen that is tilted inward. Therefore, it is possible to prevent fingers from getting caught in fittings where the sliding screen is tilted inward. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a preferred embodiment of the fitting and the closing restriction device according to the present invention will be described in detail with reference to the attached drawings. In the following, for convenience, the terms "prospect direction" and "finding direction" may be used. The prospect direction is the direction along the depth of the fitting, as shown by the arrow A in the figure. A surface along the prospect direction may be called a "prospect surface." The prospect direction is a direction along the top and bottom perpendicular to the prospect direction in the case of an object that extends along the horizontal direction, such as a lower frame. In the case of an object that extends along the vertical direction, such as a vertical frame, the horizontal direction perpendicular to the prospect direction is called the "finding direction." A surface along the prospect direction may be called a "finding surface."

[0010] (Embodiment) 1 to 4 show a fitting according to an embodiment of the present invention. The fitting shown here is called a sash window, which is equipped with a frame 10, an inner screen 20A arranged on the indoor side of the frame 10, and an outer screen 20B arranged on the outdoor side of the frame 10. The frame 10 is constructed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13, 14 on all four sides. In the illustrated example, the frame 10 is constructed by welding the ends of the upper frame 11, the lower frame 12, and the vertical frames 13, 14 made of extruded material molded from resin. Although not shown in the figures, the frame 10 is attached to the frame B by providing a connecting member such as a nail or a screw to the frame B via the mounting fins 15 provided on the outer periphery of each frame. A frame 16 is provided on each of the indoor side portions of the frame 10. The picture frames 16 are made of thick, flat boards and are provided facing the room from the interior sides of the upper frame 11, the lower frame 12, and the vertical frames 13 and 14. The ends of these picture frames 16 are connected to each other and are supported by the frame body B via the frame body 10.

[0011] The inner screen 20A is constructed by attaching an upper frame 22A, a lower frame 23A, and left and right vertical frames 24A, 25A to the four periphery of a rectangular panel 21A such as double-glazed glass. In this inner screen 20A, the lower frame 23A is the door end, and the upper frame 22A is the door end. Similarly, the outer screen 20B is constructed by attaching an upper frame 22B, a lower frame 23B, and left and right vertical frames 24B, 25B to the four periphery of a rectangular panel 21B such as double-glazed glass. In the illustrated example, the upper frames 22A, 22B, lower frames 23A, 23B, and vertical frames 24A, 25A, 24B, 25B are made of extruded resin material, and the ends of the frames are welded together, as in the case of the frame 10. The inner and outer frames 20A, 20B are configured such that when they are placed in the closed position, that is, when the lower frame 23A of the inner frame 20A is abutted against the lower frame 12 and the upper frame 22B of the outer frame 20B is abutted against the upper frame 11, the upper frame 22A of the inner frame 20A and the lower frame 23B of the outer frame 20B are arranged side by side in the forward direction, and the opening of the frame 10 can be closed.

[0012] The upper frame 22A of the inner screen 20A and the lower frame 23B of the outer screen 20B are provided with smoke deflectors 26A, 26B on the facing surfaces. The smoke deflectors 26A, 26B engage with each other when the inner screen 20A and the outer screen 20B are placed in the closed position, respectively, and function to prevent the upper frame 22A of the inner screen 20A and the lower frame 23B of the outer screen 20B from moving away from each other.

[0013] A crescent lock 27 is provided at approximately the center of the length of the upper frame 22A of the inner screen 20A. When the inner screen 20A and the outer screen 20B are locked in their closed positions, the crescent lock 27 engages with a crescent receiver (not shown) provided on the lower frame 23B of the outer screen 20B, thereby preventing the inner screen 20A and the outer screen 20B from sliding vertically.

[0014] In the fitting of this embodiment, the outer screen 20B is fixed to the frame body 10 in the above-mentioned closed position, while the inner screen 20A is supported so that it can slide up and down and can be tilted inward relative to the frame body 10. That is, the outer screen 20B is prevented from moving relative to the frame body 10 by providing connecting members (not shown) between the upper frame 22B and the upper frame 11 and between the vertical frames 24B, 25B and the vertical frames 13, 14, and is always placed in the closed position. In contrast, the inner screen 20A can slide the lower frame 23A up and down relative to the frame body 10 by the link mechanism 28 provided between the vertical frames 24A, 25A and the vertical frames 13, 14, and can rotate around the axis along the length of the lower frame 23A so that the upper frame 22A is in an inward tilted position protruding into the room. In the embodiment of the fixture, the inward tilt angle of the inner sash 20A relative to the frame 10 is limited to approximately 30° by a link mechanism 28 interposed between the vertical frames 13, 14 and the vertical stiles 24A, 25A.

[0015] In addition, latches 30 are provided at both ends of the upper frame 22A of the inner sash 20A. As shown in FIG. 5, the latch 30 is configured with a case 31 and an engagement member 32, and is configured to be symmetrical on the left and right. The case 31 has an operation guide groove 31a on the upper surface along the longitudinal direction of the upper frame 22A. The engagement member 32 has an operation protrusion 32a on the upper surface. The latch 30 is attached to the upper surface of the upper frame 22A via the case 31 with the operation protrusion 32a of the engagement member 32 slidably fitted into the operation guide groove 31a of the case 31, and the tip of the engagement member 32 can appear and disappear from the expected surface on the outer periphery side of the vertical frames 24A and 25A. As is clear from the figure, the tip of the engagement member 32 is provided with a guide surface 32b and a regulating surface 32c. Guide surface 32b is provided on the edge of engaging member 32 facing the outside of the room, and is gradually inclined toward the inside of the room toward the outer periphery. Restriction surface 32c is provided on the edge of engaging member 32 facing the inside of the room, and is provided perpendicular to the projection direction. In addition, a coil spring 33 is provided between case 31 and engaging member 32 to constantly urge engaging member 32 toward the outer periphery.

[0016] In the inner sash 20A equipped with the latch 30 described above, when the vertical frames 24A, 25A are in a position along the vertical frames 13, 14 (hereinafter referred to as the upright position) and the tip of the engagement member 32 protrudes from the visible surface of the vertical frames 24A, 25A, the regulating surface 32c of the engagement member 32 engages with the slide guides 13a, 14a provided on the vertical frames 13, 14, as shown in the left half of Figure 5. This prevents the upper frame 22A from moving toward the inside of the room relative to the frame body 10, and allows the inner sash 20A to slide up and down while maintaining the upright position relative to the frame body 10, as shown in Figure 3.

[0017] On the other hand, by moving the inner screen 20A slightly upward, the engagement state of the smoke deflectors 26A, 26B is released, and from this state, the engagement member 32 is operated via the operation protrusion 32a to move backward against the spring force of the coil spring 33, and the engagement state between the slide guides 13a, 14a of the vertical frames 13, 14 and the regulating surface 32c of the engagement member 32 is released as shown in the right half of Figure 5. Therefore, it becomes possible to move the upper frame 22A toward the inside of the room around the axis along the longitudinal direction of the lower frame 23A, and the inner screen 20A can be placed in an inward tilted position as shown in Figure 4. In this state, the surface of the inner screen 20A facing the outside is exposed to the inside of the room, which has the advantage of making cleaning easier.

[0018] When the upper frame 22A is rotated toward the outside of the room from the state in which the inner screen 20A is tilted inward, the inclination of the guide surface 32b that abuts against the vertical frames 13, 14 causes the engagement member 32 to move backward against the spring force of the coil spring 33, making it possible to return the inner screen 20A to an upright position. When the inner screen 20A is in an upright position, the spring force of the coil spring 33 causes the engagement member 32 to protrude, and the regulating surface 32c returns to a state in which it engages with the slide guides 13a, 14a of the vertical frames 13, 14.

[0019] Furthermore, the above-mentioned fitting is provided with a closure limiting device 40 at the lower end of the vertical frame 13 located on the left side when viewed from the inside of the room, as shown in Fig. 1. The closure limiting device 40 limits the movement of the inner screen 20A in the closing direction when the inner screen 20A slides upward to a height where a preset gap is created between the bottom frame 23A of the inner screen 20A and the bottom frame 12, and is indirectly provided on the frame B via the projected surface on the inner periphery of the vertical frame 13 and the projected surface on the inner periphery of the frame 16 provided on the vertical frame 13. In this embodiment, as shown in Fig. 6, the closure limiting device 40 is configured with a device main body 41 and a stopper member 42.

[0020] The device body 41 has a vertically elongated rectangular thick plate shape, and is attached to the inner surface of the vertical frame 13 and the inner surface of the frame 16 on the inner side of the sliding area of ​​the inner screen 20A via one surface 41a. The sliding area of ​​the inner screen 20A is the area that becomes the movement trajectory of the inner screen 20A when the inner screen 20A slides up and down while maintaining an upright posture. The device body 41 has a bearing hole 41c and a rotation restriction guide 41d on the other surface 41b. The bearing hole 41c is a circular recess in cross section provided at the corner on the lower side of the device body 41 and on the outer side of the room. The shaft mounting hole 41e is provided in the center of the bearing hole 41c so as to penetrate the device body 41. The rotation restriction guide 41d is an arc-shaped groove centered on the axis of the shaft mounting hole 41e, and is provided in a part above the bearing hole 41c. The central angle of the rotation restriction guide 41d is set so that the rotation angle of the stopper member 42, which will be described later, is greater than the inward tilt angle of the inner sash 20A. An engagement wall 41f is provided on the opening edge of the rotation restriction guide 41d in the outside half of the room. The engagement wall 41f protrudes from the opening edge located on the center side of the rotation restriction guide 41d toward the outer periphery, and is formed to narrow the opening width of the rotation restriction guide 41d.

[0021] The stopper member 42 is disposed so as to overlap the other surface 41b of the device body 41, and is configured to be a thick plate like the device body 41. The plate thickness of the stopper member 42 is set so that when disposed so as to overlap the device body 41, it protrudes to a position facing the vertical frame 24A of the inner screen 20A. The stopper member 42 is provided with a guide tube portion 42a and a guide protrusion 42b.

[0022] The guide tubular portion 42a is a cylindrical protrusion provided at the lower end of the stopper member 42, and is formed on a surface 42c of the stopper member 42 that faces the device body 41. The outer diameter of the guide tubular portion 42a is formed to a dimension that allows it to rotatably fit into a bearing hole 41c of the device body 41. A shaft insertion hole 42d is provided in the center of the guide tubular portion 42a so as to pass through the stopper member 42.

[0023] The guide protrusion 42b protrudes from a surface 42c of the stopper member 42 facing the device body 41 toward the device body 41, and is formed with a plate thickness that allows it to be inserted into the narrow portion of the rotation restriction guide 41d where the engagement wall portion 41f is provided. An engagement protrusion 42e is provided at the protruding end of the guide protrusion 42b. The engagement protrusion 42e protrudes from the guide protrusion 42b toward the center side. This engagement protrusion 42e is configured to be insertable into a portion of the rotation restriction guide 41d where the engagement wall portion 41f is not provided, and to face the engagement wall portion 41f when the guide protrusion 42b is disposed in the narrow portion of the rotation restriction guide 41d.

[0024] The stopper member 42 is held in a state of being superimposed on the other surface 41b of the device body 41 by fitting the guide tubular portion 42a into the bearing hole 41c with the guide projection 42b inserted into the rotation restriction guide 41d, and by mounting the shaft member 43 into the shaft mounting hole 41e via the shaft insertion hole 42d. Furthermore, as shown in Figs. 1 to 4, a spacer 44 is disposed as a load receiver between the device body 41 and the lower frame 16 so as to abut on the lower surface of the stopper member 42. A cover member 45 for hiding the shaft insertion hole 42d is provided on the surface 42f of the stopper member 42.

[0025] The stopper member 42 held in the device body 41 is in a state where the guide protrusion 42b is inserted into the rotation restriction guide 41d, and can rotate around the axis of the guide tubular portion 42a within the range where the guide protrusion 42b abuts on both ends of the arc of the rotation restriction guide 41d. In this embodiment, as shown in Figures 7 to 10, the guide protrusion 42b and the rotation restriction guide 41d are provided so that the peripheral surface of the stopper member 42 facing the outside (hereinafter referred to as the outer surface 42g) can rotate between a position approximately along the vertical direction on the inside of the room from the sliding area of ​​the inner sash 20A to a position inclined approximately 30° toward the inside of the room.

[0026] 6, a torsion coil spring (spring member) 46 that urges the stopper member 42 to rotate in one direction relative to the device body 41 is interposed between the stopper member 42 and the device body 41. In this embodiment, the torsion coil spring 46 is provided around the guide tubular portion 42a so that the stopper member 42 is always urged to rotate clockwise relative to the device body 41 when viewed from the surface 42f side of the stopper member 42, and the outer surface 42g of the stopper member 42 is maintained in a position substantially along the vertical direction, as shown in FIG.

[0027] Furthermore, the stopper member 42 is provided with an operating protrusion 42h and a closing limiting protrusion 42j, as shown in Fig. 6. The operating protrusion 42h protrudes upward from the upper end of the stopper member 42 on the inside of the room. The closing limiting protrusion 42j protrudes from the outer surface 42g of the stopper member 42 toward the outside of the room, and can appear and disappear in the sliding area of ​​the inner door 20A by the rotation of the stopper member 42 relative to the device body 41. That is, as shown in Fig. 8, when the inner door 20A slides upward and the lower end surface of the lower frame 23A is positioned above the stopper member 42, the spring force of the torsion coil spring 46 causes the stopper member 42 to rotate to the farthest outside of the room relative to the device body 41, and the closing limiting protrusion 42j stops in a state where it protrudes into the sliding area of ​​the inner door 20A. In this state, the upper end face of the closing limiting protrusion 42j faces the lower face of the bottom frame 23A, and as shown in Figure 9, when the inner screen 20A is slid downward, the closing limiting protrusion 42j comes into contact with the bottom frame 23A of the inner screen 20A, preventing the inner screen 20A from further sliding downward. As a result, even if the inner screen 20A is slid downward with fingers placed between the bottom frame 12 and the bottom frame 23A, a gap is maintained between the bottom frame 12 and the bottom frame 23A, and there is no risk of fingers getting caught.

[0028] From this state, by applying an operating force to the operating protrusion 42h and rotating the stopper member 42 toward the room against the spring force of the torsion coil spring 46, the closing limiting protrusion 42j can be retracted from the sliding area of ​​the inner screen 20A, making it possible to slide the inner screen 20A downward and place it in the closed position, as shown in Figure 7. When the operating force applied to the operating protrusion 42h of the stopper member 42 is removed with the inner screen 20A placed in the closed position, the spring force of the torsion coil spring 46 causes the closing limiting protrusion 42j of the stopper member 42 to stop in contact with the vertical frame 24A of the inner screen 20A. Therefore, when the inner screen 20A is slid upward from this state, the spring force of the torsion coil spring 46 rotates the stopper member 42 toward the outside of the room at the point when the bottom frame 23A is positioned above the stopper member 42, and the closing limiting protrusion 42j is again positioned opposite the bottom frame 23A of the inner screen 20A, as shown in Figure 8. In other words, without any operation being required, when the inner screen 20A is slid upward, the closing limiting protrusion 42j is automatically positioned opposite the bottom frame 23A, making it possible to prevent fingers from being pinched between the bottom frame 12 and the bottom frame 23A.

[0029] Moreover, the above-mentioned stopper member 42 can rotate until the outer surface 42g is inclined approximately 30 degrees toward the room side, as shown in Fig. 10. In other words, when the inner screen 20A is placed in an inward tilted position with the lower frame 23A of the inner screen 20A in contact with the stopper member 42, the stopper member 42 rotates to retreat toward the room side together with the inner screen 20A. Therefore, even when the inner screen 20A is placed in an inward tilted position, there is no risk of external force being applied that could damage the closure limiting device 40, and it is possible to prevent fingers from getting caught for a long period of time.

[0030] In the above embodiment, a sash window in which the inner screen 20A slides up and down relative to the frame 10 is shown as an example, but the present invention is not limited to this, and can also be applied to fittings such as sliding windows and single-sliding windows in which the screen slides left and right relative to the frame. Also, in the above embodiment, when applied to a sash window, an example in which the outer screen 20B is fixed to the frame 10 is shown as an example, but the present invention is not necessarily limited to this. For example, the present invention can be applied to a fitting with only one screen, or to a fitting with multiple screens that all slide.

[0031] Furthermore, in the above-mentioned embodiment, the closure limiting device 40 is provided in the portion spanning the vertical frame 13 and the frame 16, but the present invention is not limited thereto. For example, the closure limiting device 40 may be provided only on the frame 16, or may be provided only on the vertical frame 13. When the closure limiting device 40 is indirectly provided on the body B via the frame body 13 or the frame 16, it is not necessary for the connecting member such as the mounting screw for fixing the device main body 41 to reach the body B directly, and it is sufficient that it reaches the frame body 13 or the frame 16 attached to the body B. Furthermore, the closure limiting device 40 does not need to be indirectly provided on the body B via the frame 16 or the vertical frame 13, and may be directly attached to the body B. Furthermore, the closure limiting device is provided only on the left side as viewed from the inside of the room, but it may be provided only on the right side as viewed from the inside of the room, or it may be provided on both the left and right sides.

[0032] Furthermore, in the above-described embodiment, the stopper member 42 of the closure limiting device 40 is rotated relative to the device main body 41 to limit the downward movement of the inner screen 20A via the closure limiting protrusion 42j, but the present invention is not limited to this and may be configured, for example, as shown in the following modified example.

[0033] (Modification) Fig. 11 shows a fitting that is a modified example of the present invention. The fitting illustrated here is called a sash window, which is equipped with a frame body 10, an inner screen 20A arranged on the indoor side of the frame body 10, and an outer screen 20B arranged on the outdoor side of the frame body 10, just like the embodiment, and differs from the embodiment only in the configuration of the closing restriction device. Below, the configuration that differs from the embodiment will be described in detail, and the same reference numerals will be used to designate the same configuration as the embodiment, and the description will be omitted.

[0034] As is clear from the figure, the fitting of this modified example is also provided with a closure limiting device 140 at the lower end of the vertical frame 13 located on the left side when viewed from the inside of the room. The closure limiting device 140 limits the movement of the inner screen 20A in the closing direction when the inner screen 20A slides upward to a height where a preset gap is created between the bottom frame 23A of the inner screen 20A and the bottom frame 12, and is configured with a device main body 141 and a rotation support member (stopper member) 142 as shown in Figure 12.

[0035] The device body 141 has an outer shape of a vertically long rectangular thick plate, and is attached via one surface to a portion of the vertical frame 13 that is closer to the room than the sliding area of ​​the inner sash 20A on the projected surface that is the inner periphery of the vertical frame 13. Although not shown in the figure, this device body 141 has a bearing hole (41c) and a rotation restriction guide (41d) on the other surface 141b, as in the embodiment.

[0036] The rotating support member 142 is arranged so as to overlap the other surface 141b of the device body 141, and is configured to be a thick plate like the device body 141. The plate thickness of the rotating support member 142 is set so that when it is arranged overlapping the device body 141, it protrudes to a position facing the vertical frame 24A of the inner screen 20A. Although not shown in the figure, this rotating support member 142 has a guide tube part (42a) and a guide protrusion (42b) like the embodiment, and can rotate around the axis of the guide tube part (42a) within the range where the guide protrusion (42b) abuts on both ends of the arc of the rotation restriction guide (41d). In this modified example, the peripheral surface of the rotating support member 142 facing the outside of the room (hereinafter referred to as the outer surface 142g) is configured to be able to rotate between a position approximately along the vertical direction on the room side of the sliding area of ​​the inner screen 20A to a position inclined approximately 30 degrees toward the room side.

[0037] As in the embodiment, this rotation support member 142 is rotatably held in a state where it is superimposed on the other surface 41b of the device body 141. Between the rotation support member 142 and the device body 141, there is interposed a torsion coil spring 146 which urges the rotation support member 142 to rotate in one direction relative to the device body 141. In this modification, the torsion coil spring 146 is provided so as to constantly urge the rotation support member 142 to rotate clockwise relative to the device body 141 when viewed from the rotation support member 142, and to maintain the outer surface 142g of the rotation support member 142 in a position substantially along the vertical direction, as shown in Figures 12(a), 12(b), and 13.

[0038] 12, the above-mentioned rotation support member 142 is provided with a housing portion 142k that opens to an outer surface 142g, and a restriction block member (stopper member) 147 is housed in the housing portion 142k. The restriction block member 147 is supported so as to be able to advance and retreat with respect to the outer surface 142g of the rotation support member 142. A coil spring (spring member) 148 that constantly biases the restriction block member 147 in a direction that protrudes outward is interposed between the restriction block member 147 and the rotation support member 142. In order to prevent the restriction block member 147 from falling off the rotation support member 142, for example, one end of the coil spring 148 is fixed to the rotation support member 142, and the other end is fixed to the restriction block member 147.

[0039] In the closing restriction device 140 configured as described above, the restriction block member 147 can appear and disappear from the sliding area of ​​the inner door 20A. That is, when the inner door 20A slides upward and the lower end surface of the lower frame 23A is positioned above the restriction block member 147, as shown in Fig. 13, the spring force of the coil spring 148 causes the restriction block member 147 to be in a position where it protrudes most outside the room relative to the rotation support member 142, and the tip of the restriction block member 147 stops in a state where it protrudes into the sliding area of ​​the inner door 20A. In this state, the upper end surface of the restriction block member 147 is in a position facing the lower surface of the lower frame 23A, and when the inner door 20A slides downward, the restriction block member 147 abuts against the lower frame 23A of the inner door 20A, preventing the inner door 20A from sliding downward thereafter. As a result, even if, for example, fingers are placed between the bottom frame 12 and the bottom stile 23A and the inner screen 20A is slid downward, a gap is maintained between the bottom frame 12 and the bottom stile 23A, eliminating the risk of fingers getting caught.

[0040] If an operating force is applied to the restricting block member 147 from this state and the restricting block member 147 is slid toward the inside of the room against the spring force of the coil spring 148, the restricting block member 147 will retreat from the sliding area of ​​the inner door 20A, and the inner door 20A can be slid downward to the closed position as shown in Fig. 11. When the restricting block member 147 is removed from the operating force when the inner door 20A is placed in the closed position, the restricting block member 147 will stop in abutment against the vertical frame 24A of the inner door 20A due to the spring force of the coil spring 148. Therefore, if the inner door 20A is slid upward from this state, the restricting block member 147 will slide toward the outside of the room due to the spring force of the coil spring 148 at the point when the lower frame 23A is placed above the restricting block member 147, and as shown in Fig. 12, the restricting block member 147 will again be placed in a position facing the lower frame 23A of the inner door 20A. In other words, without any operation being required, when the inner screen 20A is slid upward, the restricting block member 147 is automatically positioned opposite the bottom frame 23A, thereby making it possible to prevent fingers from becoming pinched between the bottom frame 12 and the bottom frame 23A.

[0041] Moreover, the rotating support member 142 housing the above-mentioned restricting block member 147 can rotate until the outer surface 142g is inclined at approximately 30 degrees toward the room side, as shown in Figures 12(c) and 14. In other words, when the inner screen 20A is placed in an inwardly tilted position with the lower frame 23A of the inner screen 20A in contact with the rotating support member 142, the rotating support member 142 rotates together with the inner screen 20A so as to retreat toward the room side. Therefore, even when the inner screen 20A is placed in an inwardly tilted position, there is no risk of external force that could damage the closing limiting device 140 being applied, and it is possible to prevent fingers from getting caught for a long period of time.

[0042] In the above-described embodiment and variant examples, the stopper member is rotated relative to the device main body to move it retractably toward the inside of the room, but the present invention is not limited to this, and it is also possible to move it retractably toward the inside of the room by sliding it toward the inside of the room.

[0043] As described above, the fittings of the present invention are fittings comprising a shoji screen that is slidable relative to a frame body and can be moved to an inward-tilted position with the door end side protruding toward the room from the center, and a close limiting device that is directly or indirectly attached to the main body that supports the frame body and limits the sliding of the shoji screen in the closing direction, and are characterized in that the close limiting device comprises a device main body that is directly or indirectly attached to the main body, and a stopper member that is movably supported relative to the device main body, and when the shoji screen is placed in the open position, it moves forward to the outside of the room to prevent the shoji screen from sliding in the closing direction, and moves backward to the inside of the room when the shoji screen moves to the inward-tilted position. According to this invention, the stopper member is movably disposed relative to the device body, and the retracting movement eliminates the risk of damage caused by external force from the shoji screen that is tilted inward. Therefore, it is possible to prevent fingers from being caught even in fittings where the shoji screen is tilted inward. The opening and closing direction of the shoji screen may be vertical or horizontal. The retracting movement of the stopper member is not limited to rotation, and it is also possible to configure it to move linearly into the room. The device body of the closure limiting device may be directly attached to the structure, or indirectly attached to the structure via a frame or frame.

[0044] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the stopper member is rotatably supported relative to the device body in a state in which it can be displaced in the indoor / outdoor direction. According to this invention, it is possible to prevent a situation in which the stopper member is damaged due to rotation.

[0045] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the stopper member is biased toward the outside of the room so as to abut against the visible surface of the shoji screen facing the inside of the room when the shoji screen is placed in the closed position, and is moved forward and backward to the outside of the room by the biasing force when the shoji screen is moved to the open position. According to this invention, when the screen is moved to the open position, the stopper member is automatically positioned to prevent the screen from moving in the closing direction, making it possible to more reliably prevent fingers from getting caught between the screen and the frame.

[0046] Furthermore, the present invention is characterized in that in the above-mentioned fitting, the stopper member is biased toward the outside of the room by a spring member interposed between the stopper member and the device body. According to this invention, since the stopper member is biased by the spring member, it is possible to attach the stopper member without considering the direction of gravity.

[0047] In addition, the closure limiting device of the present invention is a closure limiting device that is slidable relative to a frame body and limits the sliding of a shoji screen that is in an inward-tilted position with the door end side protruding toward the inside of the room, centered on the door tip side, and is characterized in that it comprises a device main body that is directly or indirectly attached to a structure that supports the frame body, and a stopper member that is movably supported relative to the device main body, and when the shoji screen is placed in the open position, it moves forward and backward toward the outside of the room to prevent the shoji screen from sliding in the closing direction, and when the shoji screen moves to the inward-tilted position, it moves backward and toward the inside of the room. According to this invention, the stopper member is movably disposed relative to the device body, and the retractable movement eliminates the risk of damage caused by external force from the sliding screen that is tilted inward. Therefore, it is possible to prevent fingers from being caught in the sliding screen that is tilted inward. The retractable movement of the stopper member is not limited to rotation, but can also be configured to move linearly into the room. [Explanation of symbols]
