Summary of the Invention

Problems to be Solved by the Invention

[0004] When performing maintenance on the furniture, etc., it may be necessary to remove the shoji screen. In the furniture of Patent Document 1, when removing the shoji screen from the frame body, it is necessary to separate the opening / closing arm and the shoji screen. However, when a relatively large-sized frame is arranged on the indoor side of the shoji screen, it is assumed that it may be difficult to reach the connection part between the opening / closing arm and the shoji screen from the indoor side. In that case, it becomes difficult to separate the opening / closing arm and the shoji screen, and there is a risk that the removal of the shoji screen will be hindered.

[0005] An object of the present invention is to provide regulating components and furniture that facilitate the removal of the shoji screen.

[0163] Furthermore, the door / window 1 is not provided with an opening / closing arm that connects the sliding door 31 to the frame 2 and holds the sliding door 31 at a predetermined opening angle.

[0164] (Screen door) The screen door 37 is installed inside the newly installed frame 21. The screen door 37 is installed on the exterior side of the shoji screen 31. The screen door 37 has a screen door frame 38 and a screen part 39.

[0165] The screen door frame 38 is installed along the inner circumferential surface of the newly installed frame 21. The screen door frame 38 is attached to the screen door mounting portions 21Ad, 21Bc, 21Cf, and 21Df of the newly installed frame 21. The screen door frame 38 is frame-shaped, specifically rectangular. The screen door frame 38 has a hollow structure. The screen door frame 38 is made of a metal such as aluminum.

[0166] The mesh portion 39 is provided on the inner circumference side of the screen door 37. The mesh portion 39 has a roughly rectangular shape.

[0167] (Regulated parts) Here, the door / window 1 is equipped with a restricting component 50. The restricting component 50 is a member that restricts the opening movement of the sliding door 31 when the sliding door 31 is opened to a predetermined opening angle. The opening angle of the sliding door 31 refers to the angle formed by the sliding door panel in the closed state and the sliding door panel in the open state when viewed from the left to right, and is sometimes simply called the "opening angle". The predetermined opening angle is set to an angle smaller than 90°, for example.

[0168] First, the configuration of the restricting component 50 will be explained with reference to Figure 4. Note that the directions described in the explanation of the configuration of the restricting component 50 (the directions in Figure 4) refer to the directions when the restricting component 50 is attached to the joinery 1.

[0169] As shown in Figure 4, the restricting component 50 is block-shaped. The left-right dimension of the restricting component 50 is smaller than the left-right dimension of the sliding door 31. The restricting component 50 is made of, for example, resin. However, it is not limited to this, and the restricting component 50 can be made of metal, wood, etc.

[0170] The upper surface of the restrictor component 50 is formed in a stepped shape, with the exterior side being lower than the interior side. More specifically, the upper surface of the restrictor component 50 extends approximately parallel to the horizontal direction toward the interior side, then slopes upward toward the interior side, and then extends approximately parallel to the horizontal direction toward the interior side. The depth dimension of the lower portion of the upper surface of the restrictor component 50 is approximately the same as the depth dimension of the upper portion of the upper surface of the restrictor component 50.

[0171] The lower surface of the restrictor component 50 is formed in a stepped shape, with the exterior side being lower than the interior side. More specifically, the lower surface of the restrictor component 50 extends approximately parallel to the horizontal direction toward the interior side, then slopes upward toward the interior side, and then extends approximately parallel to the horizontal direction toward the interior side. The depth dimension of the lower portion of the lower surface of the restrictor component 50 is approximately the same as the depth dimension of the upper portion of the lower surface of the restrictor component 50. In the restrictor component 50, the sloped portion of the upper surface and the sloped portion of the lower surface overlap in the vertical direction.

[0172] The restricting component 50 has a screw hole 51 that penetrates it vertically. The screw hole 51 is provided, for example, on the part of the restricting component 50 that is closer to the interior side.

[0173] Next, the state in which the restrictive component 50 is attached to the joinery 1 will be explained with reference to Figure 5.

[0174] As shown in Figure 5, the restricting component 50 is provided, for example, on the frame 2. The restricting component 50 is provided on the lower frame 2A, and more specifically, on the lower frame angle 24A. The restricting component 50 is located on the interior side of the lower frame side sash connection portion 21Af.

[0175] The restricting component 50 is detachably attached to the lower frame 2A (specifically, the lower frame angle 24A). The sliding door 31 is detachably attached to the lower frame 2A while the sliding door 31 is attached to the frame 2.

[0176] In this specification, "detachable" means that different components are connected with sufficient strength, while also being able to be easily separated and then reconnected in the same manner.

[0177] The restricting component 50 is detachably fixed to the lower frame 2A by a screw B1. The screw B1 passes through the restricting component 50 in the vertical direction and is also screwed into the lower frame angle 24A.

[0178] The restricting component 50 overlaps the closed sash 31 in the vertical direction; more specifically, the portion of the sash 31 closer to the exterior side overlaps the sash 31 in the vertical direction. The exterior end of the restricting component 50 is close to or in contact with the lower frame side sash connection portion 21Af. The interior end of the restricting component 50 is located on the interior side of the interior side of the lower end of the bottom frame 32A. When the sash 31 is closed, the entire restricting component 50 is located below the interior side of the interior side of the lower end of the sash 31.

[0179] The upper surface of the restrictor component 50 is formed in a stepped shape, with the outdoor side being lower than the indoor side. The outdoor end of the upper surface of the restrictor component 50 is located lower than the indoor end of the upper surface of the restrictor component 50. The outdoor end of the upper surface of the restrictor component 50 overlaps vertically with the closed shoji screen 31. The outdoor end of the upper surface of the restrictor component 50 is located on the indoor side of the closed shoji screen 31. The inclined portion of the upper surface of the restrictor component 50 and the inclined portion of the lower surface of the restrictor component 50 are located on the indoor side of the indoor and lower ends of the lower frame 32A.

[0180] The lower surface of the restricting component 50 is formed in a stepped shape, with the outdoor side being lower than the indoor side. Similarly, the upper surface of the lower frame angle 24A is formed in a stepped shape, with the outdoor side being lower than the indoor side. The lower portion of the lower surface of the restricting component 50 faces the lower portion of the upper surface of the lower frame angle 24A. The upper portion of the lower surface of the restricting component 50 faces the upper portion of the upper surface of the lower frame angle 24A.

[0181] The entire screw head B1a of screw B1 is located on the interior side of the closed sliding door 31, and is further inward than the lower end of the door. The entire screw head B1a is housed inside the screw hole 51.

[0182] When installing the restricting component 50, it is inserted from the indoor side into the gap between the lower surface of the sash 31 and the upper surface of the lower frame angle 24A. At this time, the upper surface of the restricting component 50 is formed in a stepped shape, with the indoor side being lower than the indoor side, which allows for smooth placement of the restricting component 50. Furthermore, because the lower surface of the restricting component 50 is formed in a stepped shape, interference between the restricting component 50 and the lower frame angle 24A can be suppressed even in a configuration where the upper surface of the lower frame angle 24A is formed in a stepped shape.

[0183] Next, the function of the regulating component 50 will be explained with reference to Figures 6 and 7.

[0184] As shown in Figures 6 and 7, the sliding door 31 rotates inward and opens around the connection point between the lower frame side sliding door connection part 21Af and the sliding door side sliding door connection part 33Ac. When the sliding door 31 is opened to a predetermined opening angle, the restricting component 50 comes into contact with at least one of the lower surface of the lower frame 32A and the indoor side surface of the lower frame 32A, for example, it comes into contact with the indoor side and lower end of the lower frame 32A. When the sliding door 31 is opened to a predetermined opening angle, the restricting component 50 is sandwiched between the sliding door 31 (lower frame 32A) and the lower frame 2A (lower frame angle 24A), and more specifically, between the sliding door 31 and the top surface of the lower frame 2A. As a result, when the sliding door 31 is opened to a predetermined opening angle, its movement in the opening direction is restricted by the restricting component 50.

[0185] (Effects of the first embodiment) The restricting component 50 of this embodiment provides the following effects.

[0186] The restricting component 50 is provided on a door or window fitting that includes a frame 2 provided in an opening 101 of a building 100, a sliding door 31 provided on the inner circumference of the frame 2, without an opening / closing arm, with its lower end supported by the frame 2 and its upper end being able to tilt inward toward the interior, and frames 11, 13 provided extending further inward toward the interior than the frame 2. The restricting component 50 is provided on the frame 2 (specifically, the lower frame 2A) and, when the sliding door 31 is opened, it contacts at least one of the interior side surface of the sliding door 31 and the bottom surface of the sliding door 31 (specifically, the interior and lower end of the sliding door 31), thereby restricting the opening of the sliding door 31.

[0187] If the shoji screen and the frame are connected by an opening / closing arm that holds the shoji screen in the open position, then in order to remove the shoji screen, the connection between the shoji screen and the frame by the opening / closing arm must, in principle, be released. However, when attempting to remove the shoji screen from the interior side, if the frame extends further outward than the frame, the process of releasing the connection by the opening / closing arm may be hindered by the frame. Therefore, with this configuration, the restricting component 50 can restrict the opening of the shoji screen 31 when it is open to a predetermined opening angle. As a result, the opening / closing arm that connects the shoji screen 31 and the frame 2 to hold the shoji screen 31 in the open position can be omitted from the configuration of the joinery 1. This eliminates the need to separate the opening / closing arm from the shoji screen 31 when removing the shoji screen 31, thus making it easier to remove the shoji screen 31.

[0188] The regulatory component 50 is provided in a detachable manner.

[0189] With this configuration, the degree of freedom in opening and closing the sliding door 31 can be increased by removing the restricting component 50 from the door 1. For this reason, for example, by removing the restricting component 50 from the door 1 before removing the sliding door 31, the workability of removing the sliding door 31 can be improved. This makes it even easier to remove the sliding door 31.

[0190] Furthermore, the opening angle of the sliding door 31 can be adjusted by replacing the restricting component provided on the door 1 with a restricting component that has a different shape and dimensions from the original restricting component.

[0191] The restricting component 50 restricts the opening of the sliding door 31 by being in contact with the interior side of the sliding door 31 when the sliding door 31 is opened.

[0192] The further the position where the restricting component 50 receives the sliding door 31 is from the axis of rotation during opening and closing of the sliding door 31, the less force the restricting component 50 can apply to receive the sliding door 31. With this configuration, it is easy to move the position where the restricting component 50 receives the sliding door 31 away from the axis of rotation during opening and closing of the sliding door 31. This allows for effective restriction of the opening operation of the sliding door 31.

[0193] The restricting component 50 is sandwiched between the open sash 31 and the lower frame 2A.

[0194] With this configuration, the load acting from the sliding door 31 to the restricting component 50 can be received by the lower frame 2A. Therefore, even when a relatively large load is applied to the sliding door 31, the opening operation of the sliding door 31 can be effectively restricted while the sliding door 31 is open to a predetermined opening angle.

[0195] The restricting component 50 is detachably fixed to the lower frame 2A by a screw B1, and the entire screw head B1a of the screw B1 is located on the interior side of the closed sash 31, and is further inward than the interior side and lower end.

[0196] With this configuration, it is possible to prevent the sliding door 31 from obstructing the process of attaching and detaching the screw B1 when attaching or detaching the restricting component 50. This makes it even easier to attach and detach the restricting component 50.

[0197] The joinery 1 comprises a frame 2 provided in the opening 101 of the building 100, a sliding door 31 provided on the inner circumference of the frame 2, without an opening / closing arm, with its lower end supported by the frame and its upper end being able to tilt inward toward the interior, a newly installed frame 13 provided extending further toward the interior than the frame 2, and a restricting component 50.

[0198] With this configuration, the opening and closing arm for restricting opening and closing can be omitted from the configuration of the door 1, making it possible to provide a door 1 in which the sliding door 31 can be easily removed.

[0199] Furthermore, the left-right dimension of the restricting component 50 may be approximately the same as the left-right dimension of the lower frame 2A. The restricting component 50 may be arranged continuously across the entire left-right area between the sliding door 31 and the lower frame 2A. In that case, the opening of the sliding door 31 can be restricted more reliably.

[0200] The joinery 1 is a remodeled joinery, and the frame 2 has an existing frame 12 provided in the opening 101 of the building 100, and a new frame 21 attached to the inner circumference of the existing frame 12, and a new frame 13 provided that protrudes inward from the existing frame 12 and the new frame 21.

[0201] When door 1 is a remodeling door, the projection of the frame into the interior tends to be greater compared to when it is a door for new construction. Therefore, when door 1 is a remodeling door, the effect of door 1 can be obtained more favorably.

[0202] <Modified form of the first embodiment> Next, various modifications of the first embodiment of this disclosure will be described with reference to Figures 8 to 10. The differences from the first embodiment will be the main focus of the description. Components similar to those in the first embodiment may be given the same reference numerals as in the first embodiment and their description may be omitted.

[0203] (First variation) First, a first modification of the first embodiment will be described. In this modification, the configuration of the regulating component differs from that of the above embodiment.

[0204] In this modified example, the directions described for each configuration of the restricting component 150 (as shown in Figure 8) refer to the directions when the sliding door 31 to which the restricting component 150 is attached is in the closed position.

[0205] As shown in Figure 8, in this modified example of the restrictor part 150, the depth dimension of the lower portion of the upper surface of the restrictor part 150 is smaller than the depth dimension of the upper portion of the upper surface of the restrictor part 150. The depth dimension of the lower portion of the lower surface of the restrictor part 150 is smaller than the depth dimension of the upper portion of the lower surface of the restrictor part 150. The position where the screw hole 51 is formed in the restrictor part 150 is on the outdoor side than the position where the screw hole 51 is formed in the restrictor part 50 of the first embodiment.

[0206] As shown in Figures 9 and 10, when the restricting component 150 is attached to the door 1, at least a portion of the screw head B1a of the screw B1 is located outside the interior side of the lower end of the closed sliding door 31. The exterior end of the screw head B1a is located outside the interior side of the lower end of the sliding door 31 when the sliding door 31 is in the closed position. The interior end of the screw head B1a is located inside the interior side of the lower end of the sliding door 31.

[0207] With this configuration, the screw head B1a can be concealed by the shoji screen 31, thereby enhancing the aesthetic appeal of the joinery 1.

[0208] Furthermore, the left-right dimension of the restricting component 150 may be approximately the same as the left-right dimension of the lower frame 2A. The restricting component 150 may be arranged continuously across the entire left-right area between the sliding door 31 and the lower frame 2A. In that case, the opening of the sliding door 31 can be restricted more reliably.

[0209] (Second variation) Next, a second modification of the first embodiment will be described with reference to Figures 11 to 13. In this modification, the configuration of the regulating component differs from that of the above embodiment.

[0210] In this modified example, the directions described for each configuration of the restricting component 250 (the directions shown in Figure 11) refer to the directions when the sliding door 31 to which the restricting component 250 is attached is in the closed state.

[0211] As shown in Figure 11, in the modified regulating part 250, the upper surface of the regulating part 250 has a lower section 251 that extends inclined downward from the outdoor end toward the indoor side, a rising section 252 that extends inclined upward from the indoor end of the lower section 251 toward the indoor side, and an upper section 253 that extends inclined downward from the indoor end of the rising section 252 toward the indoor side. The direction in which the rising section 252 extends is approximately perpendicular to the direction in which the lower section 251 extends when viewed in the left-right direction. The direction in which the upper section 253 extends is approximately parallel to the direction in which the lower section 251 extends when viewed in the left-right direction.

[0212] The portion of the lower surface of the restrictor part 250 that is closer to the outdoor side is curved so as to be convex downwards when viewed in the left-right direction. The lower surface of the restrictor part 250 extends from the outdoor end of the lower surface of the restrictor part 250 inwards and downwards, in a more gentle inward and downwards, in an inward direction approximately parallel to the depth direction, in an inward and upwards, and in an inward direction approximately parallel to the depth direction.

[0213] As shown in Figure 12, when the regulating component 250 is attached to the door 1 and the sliding door 31 is in the closed position, the lower section 251 is located on the interior side of the sliding door 31 and on the exterior side of the lower end. Each portion of the lower surface of the regulating component 250 that extends parallel to the depth direction is in contact with the upper surface of the lower frame angle 24A.

[0214] As shown in Figure 13, when the shoji screen 31 is opened to a predetermined opening angle, the lower section 251 comes into contact with the lower surface of the shoji screen 31. The rising section 252 comes into contact with the interior side surface of the shoji screen. The acute angle formed by the surface direction and the vertical direction of the rising section 252 is the same as or approximately the same as the opening angle of the shoji screen 31. The angle formed by the surface direction and the visible direction of the lower section 251 is the same as or approximately the same as the opening angle of the shoji screen 31.

[0215] In this modified example, when the sliding door 31 is opened to a predetermined opening angle, the restricting component 250 is in contact with the interior side surface of the sliding door 31. This allows the restricting component 250 to stably support the load of the sliding door 31 when it is opened to a predetermined opening angle, thereby effectively restricting the opening movement of the sliding door 31.

[0216] According to this modified version, the acute angle formed by the surface direction and the vertical direction of the rising portion 252 is the same as or approximately the same as the opening angle of the sliding door 31. The angle formed by the surface direction and the visible direction of the lower portion 251 is the same as or approximately the same as the opening angle of the sliding door 31. As a result, the opening angle of the sliding door 31, which is achieved by the restricting component 250, can be easily adjusted by adjusting the inclination angle of the rising portion 252 or the inclination angle of the lower portion 251.

[0217] Furthermore, when attaching the restrictor part 250 to the door frame 1, first, the exterior end of the restrictor part 250 is inserted into the gap between the sash 31 and the lower frame 2A. The exterior end of the restrictor part 250 has a pointed shape that faces outwards. Therefore, by moving the restrictor part 250 diagonally downward so that the exterior end of the restrictor part 250 faces diagonally downward, the restrictor part 250 can be easily inserted between the sash 31 and the lower frame 2A. Next, while moving the exterior end of the restrictor part 250 upward, the restrictor part 250 is moved further outwards, and the lower surface of the restrictor part 250 comes into contact with the upper surface of the lower frame angle 24A. The lower surface of the restrictor part 250 has a portion that extends parallel to the upper surface of the lower frame angle 24A. This allows the posture of the restrictor part 250 to be stabilized with the lower section 251 and the rising section 252 tilted in the desired direction.

[0218] Furthermore, the left-right dimension of the restricting component 250 may be approximately the same as the left-right dimension of the lower frame 2A. The restricting component 250 may be arranged continuously across the entire left-right area between the sliding door 31 and the lower frame 2A. In that case, the opening of the sliding door 31 can be restricted more reliably.

[0219] (Third variation) Next, a third modification of the first embodiment will be described with reference to Figures 14 to 20. In this modification, the configuration of the regulating component differs from that of the above embodiment.

[0220] In this modified example, the directions described for each configuration of the restricting component 350 (the directions shown in Figures 14 and 15) refer to the directions when the sliding door 31 to which the restricting component 350 is attached is in the closed state.

[0221] As shown in Figures 14 to 18, the restricting component 350 in this modified example is provided on the sliding door 31, and more specifically, on the lower part of the interior side of the sliding door 31. Multiple restricting components 350 are provided, for example, two are provided. Of each restricting component 350, one is provided on the left frame 32C and the other is provided on the right frame 32D.

[0222] The restricting component 350 is block-shaped. The restricting component 350 has a stopper body portion 352 and a protruding portion 357. The shape of the restricting component 350 is, for example, symmetrical. The shape of the restricting component 350 will be described below, in principle, while viewing the stopper body portion 352 from the left-right direction.

[0223] The stopper body 352 has a polygonal columnar shape that extends in the left-right direction.

[0224] The outdoor surface of the stopper body 352 has an outdoor facing surface 353a extending parallel to the facing direction, and an outdoor inclined surface 353b connected to the lower end of the outdoor facing surface 353a, which extends in a direction that slopes downward as it moves in the left-right direction and towards the indoor side.

[0225] The exterior facing surface 353a is in contact with the exterior sides of the left frame 32C and the right frame 32D. The lower end of the exterior facing surface 353a is roughly aligned vertically with the interior and lower end of the shoji screen 31.

[0226] The exterior inclined surface 353b is located further inward and below the interior and lower end of the closed sash 31. The exterior inclined surface 353b is approximately perpendicular to the exterior facing surface 353a.

[0227] The indoor side surface of the stopper body 352 has an indoor inclined surface 354a that extends inclined upward and inward from the lower end of the outdoor inclined surface 353b, an indoor inclined surface 354b that extends inclined upward and inward from the upper end of the indoor inclined surface 354a, an indoor inclined surface 354c that extends inclined upward and inward from the upper end of the indoor inclined surface 354b, and an indoor facing surface 354d that extends parallel to the facing direction from the upper end of the indoor inclined surface 354c.

[0228] The indoor-facing inclined surface 354a is located on the indoor side and below the indoor-facing and lower end of the closed shoji screen 31. The indoor-facing inclined surface 354a is approximately perpendicular to the outdoor-facing inclined surface 353b.

[0229] The interior-side inclined surface 354b is located further inward and lower than the interior-side and lower end of the closed shoji screen 31. The vertical position of the interior-side end of the interior-side inclined surface 354a is approximately the same as the vertical position of the interior-side and lower end of the closed shoji screen 31. Viewed from left to right, the interior-side inclined surface 354b is approximately perpendicular to the interior-side inclined surface 354a.

[0230] The interior-side inclined surface 354c is aligned in the depth direction with the interior-side and lower end of the closed shoji screen 31. The interior-side inclined surface 354c is approximately perpendicular to the interior-side inclined surface 354b.

[0231] The interior facing surface 354d is approximately parallel to the exterior facing surface 353a. The interior facing surface 354d is approximately parallel to the interior side of the closed shoji screen 31. However, in a plan view, the middle part of the interior facing surface 354d in the left-right direction is recessed toward the exterior, and more specifically, it is recessed in the shape of a groove that opens toward the interior and extends vertically.

[0232] The upper surface of the restricting component 350 has an upper surface portion 355 that connects the upper end of the outdoor-facing surface 353a and the upper end of the indoor-facing surface 354d, and extends parallel to the depth direction. However, in a plan view, the middle portion of the indoor-facing edge of the upper surface portion 355 in the left-right direction is slightly concave toward the outdoor side.

[0233] The protrusions 357 are provided on the interior-facing surface 354d. Multiple protrusions 357 are provided, for example, spaced apart in the left-right direction (more specifically, two). Each protrusion 357 is convex toward the interior from the interior-facing surface 354d. Each protrusion 357 is provided along each left-right edge of the interior-facing surface 354d. Each protrusion 357 is provided on either side of a recess formed in the interior-facing surface 354d.

[0234] Each projection 357 is a short, roughly triangular prism shape extending in the left-right direction. The indoor-facing surface of each projection 357 has an indoor-facing inclined surface 357a that extends inclined upward and inward from the lower end of each projection 357, and an indoor-facing inclined surface 357b that extends inclined upward and outward from the upper end of the indoor-facing inclined surface 357a toward the upper end of each projection 357.

[0235] The indoor-facing inclined surface 357a is connected to the indoor-facing inclined surface 354c of the stopper body 352. The indoor-facing inclined surface 354c and the indoor-facing inclined surface 357a are flush with each other.

[0236] The indoor-facing inclined surface 357b is connected to the upper surface 355 of the stopper body 352. The indoor-facing inclined surface 357b is approximately perpendicular to the indoor-facing inclined surface 357a.

[0237] The restricting component 350 has screw holes 351 formed in it that penetrate the stopper body portion 352 in the depth direction, and more specifically, there are multiple (more specifically, four) screw holes 351 formed in it. Each screw hole 351 penetrates from the indoor side surface 354d to the outdoor side surface 353a. Each screw hole 351 opens in the area of ​​the indoor side surface 354d sandwiched between the protrusions 357. Each screw hole 351 is spaced apart in the vertical direction. Each screw hole 351 is spaced apart in the horizontal direction.

[0238] The restricting component 350 is detachably fixed to the interior side of the sliding door 31, and more specifically, it is detachably fixed to either the left frame 32C or the right frame 32D by a plurality of screws B2 that penetrate the restricting component 350 in the depth direction.

[0239] Each screw B2 is inserted through a screw hole 351 formed in the restricting component 350 from the indoor side to the outdoor side, and is screwed into the indoor side of the sash 31. The entire screw head B2a of each screw B2 is located on the indoor side of the indoor side of the sash 31 when it is closed, and is further inward than the lower end.

[0240] Furthermore, the configuration of the restricting component fixed to the sliding door 31 is not limited to the configuration of the restricting component 350 described above. For example, the number and position of the protrusions 357 provided on the restricting component 350 are not particularly limited. The protrusions 357 are not an essential component. The restricting component 350 does not necessarily have to be formed symmetrically. The number of screws B2 used to fix the restricting component 350 is not particularly limited.

[0241] The left-right dimension of the restricting component 350 may be approximately the same as the left-right dimension of the lower frame 2A. The restricting component 350 may be arranged continuously across the entire left-right area between the sliding door 31 and the lower frame 2A. In that case, the opening of the sliding door 31 can be restricted more reliably.

[0242] Furthermore, the number of restricting components fixed to the shoji screen 31 is not particularly limited; it may be one or three or more. The parts of the shoji screen 31 on which the restricting component 350 is provided are not limited to the left frame 32C and the right frame 32D. The restricting component 350 may be provided, for example, on the bottom frame 32A.

[0243] As shown in Figures 19 and 20, when the sliding door 31 is opened to a predetermined opening angle, the indoor-side inclined surface 354a and the indoor-side inclined surface 357a of the restricting component 350 come into contact with the upper surface of the lower frame 2A (specifically, the lower frame angle 24A). The restricting component 350 is sandwiched between the sliding door 31 and the lower frame 2A, in contact with the indoor side surface of the sliding door 31 and the upper surface of the lower frame 2A. This allows the load of the sliding door 31 to be stably supported when the sliding door 31 is opened to a predetermined opening angle, thus effectively restricting the opening operation of the sliding door 31.

[0244] Furthermore, because the restricting component 350 is provided with a protrusion 357, the contact area between the restricting component 350 and the lower frame 2A is increased by the area of ​​the indoor-facing inclined surface 357a of the protrusion 357. As a result, the load acting from the sash 31 on the restricting component 350 can be effectively received by the lower frame 2A.

[0245] The restricting component 350, when the sliding door 31 is opened, is in contact with the interior side of the sliding door 31, thereby restricting the opening of the sliding door 31.

[0246] With this configuration, the restricting component 50 can receive the sliding door 31 at a position relatively far from the axis of rotation when the sliding door 31 is opened or closed, thus effectively restricting the opening operation of the sliding door 31.

[0247] In the regulated part 350, the exterior facing surface 353a is the surface that abuts against the interior side surface of the sash 31. The interior inclined surface 354a, interior inclined surface 354c, and interior inclined surface 357a are surfaces that abut against the upper surface of the lower frame 2A in the closed state. The acute angle formed by the interior inclined surface 354a and the exterior facing surface 353a is the same as or approximately the same as the opening angle of the sash 31, and the acute angle formed by the interior inclined surface 354a, interior inclined surface 354c, and interior inclined surface 357a is the same as or approximately the same as the opening angle of the sash 31. Therefore, the opening angle of the sash 31 can be adjusted by adjusting the angles formed by the exterior facing surface 353a and the interior inclined surfaces 354a, 354c, and 357a.

[0248] In the door / window 1, multiple (specifically, two) restricting components 350 are provided at intervals in the left-right direction.

[0249] With this configuration, water can flow down between the restricting parts 350, thereby improving drainage. Furthermore, by making the restricting parts 350 smaller, the restricting parts 350 can be made less conspicuous, improving the design, and the material used for the restricting parts 350 can be reduced, thereby lowering costs. In addition, if foreign matter gets caught between the restricting parts 350 and the lower frame 2A, it may interfere with the opening and closing of the sliding door 31. By reducing the contact area between the restricting parts 350 and the lower frame 2A, the possibility of foreign matter getting caught between the restricting parts 350 and the lower frame 2A can be reduced.

[0250] <Second Embodiment> Next, a second embodiment of this disclosure will be described with reference to Figures 21 to 23. The explanation will focus on the differences from the first embodiment. Components similar to those in the first embodiment may be denoted by the same reference numerals and their description may be omitted.

[0251] In the second embodiment, the position where the restricting component is provided in the joinery 1 differs from that in the first embodiment. As shown in Figures 21 and 22, the restricting component 450 in the second embodiment is provided on the frame. The restricting component 450 is provided, for example, on the newly installed right frame 13D, and more specifically, on the left side of the newly installed right frame 13D. The restricting component 450 is located on the interior side of the shoji screen 31.

[0252] The right end of the restrictor component 450 is fixed to the left side of the newly installed right frame 13D. The restrictor component 450 is cantilevered by the newly installed right frame 13D. The method of fixing the restrictor component 450 to the newly installed right frame 13D is not particularly limited and may include, for example, screwing, double-sided tape, or adhesive bonding.

[0253] In the second embodiment, the shape of the restricting component 450 is rod-shaped. The restricting component 450 is, for example, elongated with the left-right direction as its longitudinal direction, and more specifically, elongated cylindrical in shape.

[0254] The entire restricting component 450 is located above the lower end of the sliding door 31. The restricting component 450 is aligned with the middle of the sliding door 31 in the vertical direction and in the depth direction.

[0255] When the sliding door 31 is closed, the restricting component 450 is not in contact with any components other than the newly installed frame 13.

[0256] As shown in Figure 23, when the sliding door 31 is open to a predetermined opening angle, the restricting component 450 is in contact with the interior side of the sliding door 31. The restricting component 450 supports the sliding door 31, which is open to a predetermined opening angle, from below, specifically from the interior side and from below. This allows the opening operation of the sliding door 31 to be restricted when it is open to a predetermined opening angle.

[0257] Furthermore, the opening angle of the sliding door 31, which is held in place by the restricting component 450, can be adjusted by adjusting the vertical and horizontal position of the restricting component 450 (in other words, by adjusting the positional relationship between the sliding door 31 and the restricting component 450).

[0258] (Effects of the second embodiment) The restricting component 450 of this embodiment provides the following effects.

[0259] According to this embodiment, the restricting component 450 is formed in an elongated shape, and the longitudinal end of the restricting component 450 is connected to the newly installed frame 13.

[0260] With this configuration, compared to a configuration in which the restricting component is provided between the sliding door 31 and the lower frame 2A, the installation and removal of the restricting component 450 can be made easier. Furthermore, when removing the sliding door 31, it is preferable to remove the restricting component 450 first before removing the sliding door 31. Because the attachment and detachment of the restricting component 450 is easy, the series of operations can be carried out smoothly, making it easy to replace the sliding door 31.

[0261] Furthermore, with this configuration, the opening angle of the sliding door 31 can be adjusted by adjusting the position where the restricting component 450 is attached to the newly installed frame 13. This increases the versatility of restricting components 450 of the same shape.

[0262] According to this embodiment, the entire regulating component 450 is located above the interior side and lower end of the sliding door 31.

[0263] If the corner of the sliding door 31 comes into contact with the restricting component, depending on the material of the sliding door 31 and the restricting component, the corner of the sliding door 31 and the restricting component may become dented or worn down. However, with this configuration, the entire restricting component 450 is located above the interior side and lower end of the sliding door 31. Therefore, when the sliding door 31 is in the open position, it is possible to prevent the corner of the sliding door 31 from coming into contact with the restricting component 450. This reduces wear and tear on the sliding door 31 and the restricting component 50.

[0264] While embodiments of the building components described herein have been explained above, the invention is not limited to the embodiments described above, and any modifications, improvements, etc., within the scope that can achieve the purpose of this disclosure are included. Various modifications and changes that do not depart from the gist of this disclosure are included herein.

[0265] In each of the embodiments described above, the door 1 was a remodeled door, but it is not limited to this. The door is not limited to one installed through renovation, but may also be newly installed. However, when the door is a remodeled door, the projection of the frame into the interior tends to be larger, so the effects of the door described above are more favorably exhibited when the door is a remodeled door. Also, when the door is a remodeled door, the type of existing door is not particularly limited.

[0266] According to the embodiments described above, the door 1 was installed in a bathroom, but it is not limited to this. However, when the door is installed in a bathroom as a remodeling door, the frame tends to protrude more inward into the room in order to allow for the placement of bathroom piping etc. within the frame, so the effects of the door described above are more preferably exhibited when the door is installed in a bathroom.

[0267] According to the embodiments described above, the door 1 was installed on an upper floor of the second floor or higher, but it is not limited to this. However, when the door is installed on an upper floor, it is difficult to remove the opening and closing arm that connects the sash and the frame from the outside, so the effect of being able to omit the opening and closing arm for opening and closing restriction from the configuration of the door is more preferably exhibited when the door is installed on an upper floor.

[0268] According to each of the above first embodiments, only one of the restricting components provided on the shoji 31 and the restricting components provided on the lower frame 2A was provided on the fitting 1, but the present invention is not limited to this. Both the restricting components provided on the shoji and the restricting components provided on the lower frame may be provided on the fitting. In that case, in a state where the shoji is opened, the restricting components provided on the shoji and the restricting components provided on the lower frame may be configured to abut against each other.

[0269] In this specification, the state where "the restricting component and the shoji are in contact" includes not only the state where the restricting component and the shoji are in direct contact with each other, but also the state where another restricting component is sandwiched between the restricting component and the shoji. Similarly, the state where "the restricting component and the frame body are in contact" includes not only the state where the restricting component and the frame body are in direct contact with each other, but also the state where another restricting component is sandwiched between the restricting component and the frame body.

[0270] The restricting components of each of the above first embodiments may be provided only in a partial range in the left-right direction of the region between the shoji 31 and the frame body 2, or may be arranged continuously over the entire left-right direction of the region between the shoji 31 and the frame body 2.

[0271] In the above first embodiment, the first modification example, and the second modification example of the first embodiment, the restricting component was provided on the angle 24 of the frame body 2, but it may be provided on a part of the frame body 2 other than the angle 24. The restricting component may be provided on, for example, the newly installed frame 21.

[0272] In the above second embodiment, the restricting component 450 was fixed to the newly installed right side molding 13D, but the present invention is not limited to this. The restricting component 450 can be fixed to at least any one of the newly installed lower side molding 13A, the newly installed upper side molding 13B, the newly installed left side molding 13C, and the newly installed right side molding 13D.

[0273] In the second embodiment described above, the regulating component 450 has an elongated shape with the longitudinal direction being the left-right direction. However, the direction in which the regulating component 450 extends can be arbitrarily changed. For example, when the regulating component 450 is provided on the newly installed upper frame edge 13B or the newly installed lower frame edge 13A, the regulating component 450 can be formed, for example, in an elongated shape with the longitudinal direction being the up-down direction.

[0274] In the second embodiment described above, the shape of the regulating component 450 was an elongated cylindrical shape, but it is not limited thereto. For example, the regulating component 450 may be, for example, a polygonal cylindrical shape. Further, the regulating component 450 is not limited to having a hollow structure and may be formed solid. Also, the shape of the regulating component 450 is not limited to a straight line shape and may be curved as long as it is elongated as a whole. The regulating component 450 can be formed, for example, in an L shape, a T shape, etc. The longitudinal dimension of the regulating component 450 may be, for example, substantially the same as the distance between the left frame 2C and the right frame 2D. The regulating component 450 does not have to be supported by the frame body 2 in a cantilevered manner and may be, for example, spanned between the left frame 2C and the right frame 2D.

[0275] The present disclosure includes the regulating component and the fitting described in the following aspects. <Aspect 1> A regulating component used for a fitting including a frame body provided at an opening of a building, a shoji provided on the inner peripheral side of the frame body, having no opening / closing arm, and having a lower end supported by the frame body and an upper end side configured to be able to fall inward toward the indoor side, and a frame edge provided so as to project inward from the frame body toward the indoor side, the regulating component being provided on at least one of the frame body, the shoji, and the frame edge, and regulating the opening of the shoji by abutting against at least one of the indoor side surface and the lower surface of the shoji when the shoji is opened. <Aspect 2> The regulating component according to Aspect 1, which regulates the opening of the shoji in a state of abutting against the indoor side surface of the shoji when the shoji is opened. <Aspect 3> The aforementioned restrictive component is a restrictive component according to embodiment 1 or 2, which is detachably provided. <Aspect 4> The frame has a lower frame, and the restricting component is sandwiched between the open sliding door and the lower frame, as described in embodiments 1 to 3. <Aspect 5> The restricting component according to embodiment 4, wherein the restricting component is detachably fixed to the lower frame by a screw, and the entire head of the screw is located on the interior side of the closed sash and on the interior side of the lower end. <Aspect 6> The restricting component according to embodiment 1 or 2, wherein the restricting component is formed in an elongated shape, and the longitudinal end of the restricting component is connected to the frame. <Aspect 7> A frame provided in the opening of a building; a shoji screen provided on the inner circumference of the frame, without an opening / closing arm, whose lower end is supported by the frame and whose upper end is configured to tilt inward toward the interior; a frame provided extending further toward the interior than the frame; and a restricting component as described in any one of embodiments 1 to 6.
