Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the fitting described in Patent Document 1, since the frame-side receiving member is inserted into the recess of the shoji-side receiving member when the shoji is in the closed state, there is a limit to the expected size of the contact surface of the shoji-side receiving member against which the stopper member abuts. For this reason, when the shoji collides with the stopper member, the shoji-side receiving member may be damaged.

[0005] An object of the present invention is to provide a fitting capable of suppressing damage to a shoji-side receiving member when the shoji collides with a stopper member.

Means for Solving the Problems

[0006] The fitting of the present invention has a frame body, a shoji door that slides within the frame body, and a stopper member that advances and retracts with respect to the movement path of the shoji door. The fitting includes a stopper device provided on a first vertical frame of the frame body that faces the door end frame of the shoji door, a shoji-side contact surface against which the stopper member in the operating state advancing into the movement path can abut, a shoji-side receiving portion provided on the door end frame, a frame-side contact surface against which the stopper member in the operating state can abut, and a frame-side receiving portion provided on the first vertical frame. The shoji-side receiving portion and the frame-side receiving portion are provided so as to face each other in the vertical direction when the shoji door is in the closed state.

Advantages of the Invention

[0007] According to the present invention, it is possible to provide a fitting that can suppress damage to the shoji-side receiving member when the shoji door collides with the stopper member.

The sliding window 1, which is a fitting shown in FIG. 1, is installed in an opening of a building such as a building, and includes a window frame 2 as a frame body, an outer shoji 3 and an inner shoji 4 that are slidably arranged in a sliding manner within the window frame 2, a first stopper device 5A, and a second stopper device 5B. In the following description, the left - right direction of the sliding window 1 is defined as the X - axis direction, the up - down direction of the sliding window 1 is defined as the Y - axis direction, and the prospective direction of the sliding window 1 is defined as the Z - axis direction. The X, Y, and Z - axis directions are perpendicular to each other.

[0010] As shown in FIGS. 2 and 3, the window frame 2 includes an upper frame 21, a lower frame 22, a first vertical frame 23, and a second vertical frame 24 that are assembled in a four - sided frame. The upper frame 21, the lower frame 22, and the first and second vertical frames 23, 24 are configured by connecting an outdoor - side metal frame material 211, 221, 231, 241 and an outdoor - side resin frame material 212, 222, 232, 242. On the metal frame material 211 of the upper frame 21, an outdoor - side upper rail 211A and an indoor - side guide groove 211B are formed along the X - axis direction. On the metal frame material 221 of the lower frame 22, an outdoor - side lower rail 221A and an indoor - side lower rail 221B are formed along the X - axis direction. On the outdoor side of the metal frame material 231 of the first vertical frame 23, a pulling piece 231A protruding toward the second vertical frame 24 side is provided along the Y - axis direction. On the resin frame material 232 of the first vertical frame 23, a cut - out portion 232A is provided, which is formed by cutting out a portion corresponding to the mounting position of a first stopper body 51A described later. On the indoor side of the metal frame member 241 of the second vertical frame 24, a pulling piece 241A protruding toward the first vertical frame 23 side is provided along the Y-axis direction. An excision part 241A1 (see Fig. 5(B)) is provided on the pulling piece 241A, which is formed by excising a portion corresponding to the height position where the second shoji-side receiving member 6B and the second frame-side receiving member 7B, which will be described later, are provided.

[0011] Each shoji 3, 4 (outer shoji 3 and inner shoji 4) includes a frame body 35, 45 in which an upper frame 31, 41, a lower frame 32, 42, a door tip frame 33, 43, and a mating frame 34, 44 are assembled in a four-sided frame structure, and panels 36, 46 formed of laminated glass and arranged inside the frame body 35, 45.

[0012] The upper frame 31, the lower frame 32, the door tip frame 33, and the mating frame 34 of the outer shoji 3 are configured by connecting a metal frame member 311, 321, 331, 341 on the outdoor side and a resin frame member 312, 322, 332, 342 on the indoor side. At the upper end of the metal frame member 311 of the upper frame 31, a guide member 311A into which the outdoor-side upper rail 211A of the upper frame 21 is fitted is provided. At both ends in the X-axis direction of the metal frame member 321 of the lower frame 32, one door wheel 37 each for running on the outdoor-side lower rail 221A of the lower frame 22 is provided. On the outdoor side of the portion of the metal frame member 331 of the door tip frame 33 facing the first vertical frame 23, an engaging recess 331A is provided along the Y-axis direction, which is formed in a shape where the first vertical frame 23 side is open and the pulling piece 231A of the first vertical frame 23 engages when the outer shoji 3 is in the closed state. On the indoor side of the engaging recess 331A in the metal frame member 331 of the door tip frame 33, an indoor-side recess 331B is provided along the Y-axis direction, which is formed in a shape where the first vertical frame 23 side is open. The indoor-side recess 331B includes a bottom 331B1 and a pair of side portions 331B2 extending along the X-axis direction from the outdoor-side and indoor-side ends of the bottom 331B1 toward the first vertical frame 23 side.

[0013] The upper frame 41, lower frame 42, door edge frame 43 and joint frame 44 of the inner shoji screen 4 are constructed by connecting metal frame materials 411, 421, 431, 441 on the outside of the room and plastic frame materials 412, 422, 432, 442 on the inside of the room. The upper end of the metal frame material 411 of the upper frame 41 is fitted into the indoor guide groove 211B of the upper frame 21. At both ends in the Y-axis direction of the metal frame material 421 of the lower frame 42, one door roller 47 running on the indoor side lower rail 221B of the lower frame 22 is provided. The metal frame material 431 of the door end frame 43 has a portion facing the second vertical frame 24 that is open on the second vertical frame 24 side, and an engagement recess 431A is provided along the Y-axis direction to engage with the pulling piece 241A of the second vertical frame 24 when the inner shoji screen 4 is closed. The engagement recess 431A has a bottom 431A1 and a pair of side portions 431A2 that extend from the outdoor and indoor ends of the bottom 431A1 toward the second vertical frame 24 along the X-axis direction.

[0014] The first and second stopper devices 5A and 5B are mounted, for example, at a position approximately 150 cm above the floor of the room. As shown in Figures 3 and 4, the first stopper device 5A is mounted on the interior side of the metal frame material 231 of the first vertical frame 23, at a location that does not face the door frame 33 of the outer shoji screen 3. The second stopper device 5B is mounted on the interior side of the metal frame material 241 of the second vertical frame 24, at a location in the center of the projection direction that does not face the door frame 43 of the inner shoji screen 4. The first stopper device 5A includes a first stopper body 51A, a first stopper member 52A, and a first rotation restriction arm 53A. The second stopper device 5B includes a second stopper body 51B, a second stopper member 52B, and a second rotation restriction arm 53B.

[0015] The first stopper body 51A is directly attached to the metal frame material 231 with a portion thereof inserted through the cutout 232A in the resin frame material 232 of the first vertical frame 23. The second stopper body 51B is attached to the metal frame material 241.

[0016] The first and second stopper members 52A and 52B are rotatably provided on the first and second stopper bodies 51A and 51B via a rotation axis (not shown) parallel to the X-axis direction. The first stopper member 52A is biased by a coil spring (not shown) so as to rotate counterclockwise when viewed from the second vertical frame 24 side, that is, so as to enter an operating state of advancing with respect to the movement path of the outer shutter 3 as shown in FIG. 4. The second stopper member 52B is biased by a coil spring (not shown) so as to rotate clockwise when viewed from the first vertical frame 23 side, that is, so as to enter an operating state of advancing with respect to the movement path of the inner shutter 4. The rotation of the first and second stopper members 52A and 52B is restricted in the operating state by a rotation restricting portion (not shown) of the first and second stopper bodies 51A and 51B.

[0017] The first and second rotation restricting arms 53A and 53B are rotatably provided on the first and second stopper bodies 51A and 51B via a rotation axis (not shown) parallel to the Y-axis direction. As shown in FIG. 4, when the first and second stopper members 52A and 52B are in the operating state, the virtual line connecting the tip end and the rotation center thereof is substantially parallel to the Z-axis direction. As shown in FIG. 3, when the first and second stopper members 52A and 52B are in the standby state of retreating from the movement paths of the respective shutters 3 and 4, the tip ends thereof are configured to rotate in accordance with the rotation of the first and second stopper members 52A and 52B so as to be located at positions away from the center in the finding direction of the window frame 2 from the rotation axis. When the first and second stopper members 52A and 52B are in the standby state, the first and second rotation restricting arms 53A and 53B restrict the rotation of the first and second stopper members 52A and 52B due to the biasing of the coil spring in a state where the first and second stopper members 52A and 52B are separated from the door end frames 33 and 43 by the tip end sides thereof abutting against the finding surface on the indoor side of the door end frame 33 of the outer shutter 3 or the finding surface on the outdoor side of the door end frame 43 of the inner shutter 4.

[0018] As shown in Figures 3, 4, 5(A) and (B), the sliding window 1 further includes a first shoji side support member 6A, a second shoji side support member 6B, a first frame side support member 7A and a second frame side support member 7B.

[0019] The first shoji-side support member 6A is disposed in the room-side recess 331B of the door frame 33. The second shoji-side support member 6B is disposed in the engagement recess 431A of the door frame 43. The first and second shoji-side support members 6A and 6B are formed by bending metal plate and include first and second fixing portions 61A and 61B and first and second shoji-side support portions 62A and 62B. The first and second shoji-side support portions 62A and 62B include first and second shoji-side opposing pieces 63A and 63B, first and second shoji-side support pieces 64A and 64B, and first and second shoji-side leg pieces 65A and 65B. Examples of materials for the first and second shoji-side support members 6A and 6B include stainless steel and steel, but resin may also be used. In this way, by forming the first and second shoji side support members 6A, 6B by bending metal plate, the first and second shoji side support members 6A, 6B can be made lighter and the amount of material used can be reduced.

[0020] The first fixing portion 61A is fixed in surface contact with the bottom 331B1 by a first screw 67A that penetrates the first fixing portion 61A and the bottom 331B1 of the indoor recess 331B and is screwed into the first back plate 66A. The second fixing portion 61B is fixed in surface contact with the bottom 431A1 by a second screw 67B that penetrates the second fixing portion 61B and the bottom 431A1 of the engagement recess 431A and is screwed into the second back plate 66B so that the second shoji side receiving portion 62B is located between the upper and lower ends of the cutout portion 241A1.

[0021] The first shoji-side facing piece 63A is provided so as to extend from the upper edge of the first fixing part 61A along the X-axis direction toward the first vertical frame 23, and so that its length, when viewed from inside the room, is the same as the length of the side part 331B2 of the indoor recess 331B. The second shoji-side facing piece 63B is provided so as to extend from the upper edge of the second fixing part 61B along the X-axis direction toward the second vertical frame 24, and so that its length, when viewed from inside the room, is the same as the length of the side part 431A2 of the engagement recess 431A.

[0022] The first and second shoji-side receiving pieces 64A, 64B are provided to extend upward along the Y-axis direction from the extending tips of the first and second shoji-side opposing pieces 63A, 63B. The first and second shoji-side receiving pieces 64A, 64B have first and second shoji-side abutment surfaces 641A, 641B that can abut against the first and second stopper members 52A, 52B in the operating state.

[0023] The first and second shoji side leg pieces 65A, 65B extend from the extending tips (upper ends) of the first and second shoji side receiving pieces 64A, 64B along the X-axis direction toward the bottom parts 331B1, 431A1, and are arranged so that their extending tips abut against the bottom parts 331B1, 431A1. In this way, by providing first and second shoji side leg pieces 65A, 65B extending toward the bottom 331B1, 431A1 at the extending tips of the first and second shoji side support pieces 64A, 64B, the possibility of users of the sliding window 1 touching the edges of the first and second shoji side support members 6A, 6B can be reduced. Furthermore, since the extended tips of the first and second shoji side leg pieces 65A, 65B abut against the bottoms 331B1, 431A1, the impact when the first and second shoji side support members 6A, 6B collide with the first and second stopper members 52A, 52B can be absorbed by the first and second shoji side leg pieces 65A, 65B, thereby suppressing deformation of the first and second shoji side support members 6A, 6B.

[0024] The first frame-side receiving member 7A is disposed at a position facing the indoor-side recess 331B of the door-end frame 33 in the first vertical frame 23. The second frame-side receiving member 7B is disposed within the cutout portion 241A1 of the pulling piece 241A in the second vertical frame 24. The first and second frame-side receiving members 7A and 7B are formed by bending a metal plate, and include first and second fixing portions 71A and 71B, and first and second frame-side receiving portions 72A and 72B. The first and second frame-side receiving portions 72A and 72B include first and second frame-side opposing pieces 73A and 73B, first and second frame-side receiving pieces 74A and 74B, and first and second frame-side leg pieces 75A and 75B. As the material of the first and second frame-side receiving members 7A and 7B, the materials exemplified as the materials of the first and second shoji-side receiving members 6A and 6B can be used. Thus, by forming the first and second frame-side receiving members 7A and 7B by bending a metal plate, the weight of the first and second frame-side receiving members 7A and 7B can be reduced, and the amount of material used can be decreased.

[0025] The first fixing portion 71A penetrates through the metal frame member 231 of the first fixing portion 71A and the first vertical frame 23 so that the first frame-side receiving portion 72A is positioned below the first shoji-side receiving portion 62A, and is fixed in a state of surface contact with the metal frame member 231 by a first screw 77A screwed into the first back plate 76A. The second fixing portion 71B penetrates through the metal frame member 241 of the second fixing portion 71B and the second vertical frame 24 so that the second frame-side receiving portion 72B is positioned between the upper end and the lower end of the cutout portion 241A1 and below the second shoji-side receiving portion 62B, and is fixed in a state of surface contact with the metal frame member 241 by a second screw 77B screwed into the second back plate 76B.

[0026] The first frame-side facing piece 73A is provided so as to extend from the lower edge of the first fixing part 71A along the X-axis direction toward the door stile 33, and so as to be longer in length than the pulling piece 231A when viewed from inside the room. The second frame-side facing piece 73B is provided so as to extend from the lower edge of the second fixing part 71B along the X-axis direction toward the door stile 43, and so as to be longer in length than the pulling piece 241A when viewed from inside the room.

[0027] The first and second frame-side receiving pieces 74A and 74B are provided to extend downward along the Y-axis direction from the extending tips of the first and second frame-side opposing pieces 73A and 73B. The first and second frame-side receiving pieces 74A and 74B have first and second frame-side abutment surfaces 741A and 741B that can abut against the first and second stopper members 52A and 52B in the operating state.

[0028] The first and second frame side leg pieces 75A, 75B extend from the extending tips (lower ends) of the first and second frame side receiving pieces 74A, 74B along the X-axis direction toward the metal frame materials 231, 241, and are arranged so that their extending tips abut against the metal frame materials 231, 241. In this way, by providing first and second frame side leg pieces 75A, 75B extending toward the metal frame materials 231, 241 at the extended tips of the first and second frame side support pieces 74A, 74B, the possibility of users of the sliding window 1 touching the edges of the first and second frame side support members 7A, 7B can be reduced. Furthermore, since the extended tips of the first and second frame side leg pieces 75A, 75B abut against the metal frame materials 231, 241, the impact when the first and second frame side support members 7A, 7B collide with the first and second stopper members 52A, 52B can be absorbed by the first and second frame side leg pieces 75A, 75B, thereby suppressing deformation of the first and second frame side leg pieces 75A, 75B.

[0029] By arranging the first and second shoji side support members 6A, 6B and the first and second frame side support members 7A, 7B as described above, when each shoji 3, 4 is in the closed state, the first and second shoji side support portions 62A, 62B and the first and second frame side support portions 72A, 72B face each other in the vertical direction while being spaced apart from each other, as shown in Figures 6(A) and (B). With this configuration, there is no need to provide recesses in the first and second shoji-side support members 6A and 6B for the first and second frame-side support portions 72A and 72B to fit into when the shoji screens 3 and 4 are closed, so the projected dimensions of the first and second shoji-side contact surfaces 641A and 641B can be made larger than in the configuration described in Patent Document 1, which provides such recesses. Therefore, when the shoji screens 3 and 4 collide with the first and second stopper members 52A and 52B, the impact per unit area received by the first and second shoji-side contact surfaces 641A and 641B can be reduced, and damage to the first and second shoji-side support members 6A and 6B can be suppressed.

[0030] The distance G1 between the first shoji-side receiving portion 62A and the first frame-side receiving portion 72A, and the distance G2 between the second shoji-side receiving portion 62B and the second frame-side receiving portion 72B are set as follows. As shown in FIG. 7(A), the door rollers 37, 47 provided on the shoji screens 3, 4, respectively, are attached to the lower frames 32, 42 via height adjustment mechanisms 37A, 47A so that the height positions relative to the lower frames 32, 42 can be adjusted. As shown in Figure 7(A), when the sliding window 1 is first installed, the window frame 2 is installed in an undeformed state, that is, with the first and second vertical frames 23, 24 perpendicular to the upper frame 21 and lower frame 22. In this state, in order to ensure the airtightness of the sliding window 1, the height positions of the rollers 37, 47 of each shoji screen 3, 4 relative to the lower frames 32, 42 are adjusted to the same height so that the first and second vertical frames 23, 24 and the door end frames 33, 43 are parallel. As shown in Figure 7(B) or 7(C), the window frame 2 may become deformed after a long period of time has passed since the installation of the sliding window 1. As shown in Figure 7(B), if the angle between the bottom frame 22 and the first vertical frame 23 becomes an obtuse angle and the angle between the bottom frame 22 and the second vertical frame 24 becomes an acute angle, the height position of the rollers 37, 47 on the second vertical frame 24 side relative to the bottom frame 32, 42 of each shoji screen 3, 4 is adjusted so that it is lower than the height position of the rollers 37, 47 on the first vertical frame 23 side, in order to make the first and second vertical frames 23, 24 parallel to the door stiles 33, 43. As shown in Figure 7 (C), when the angle between the bottom frame 22 and the first vertical frame 23 becomes an acute angle and the angle between the bottom frame 22 and the second vertical frame 24 becomes an obtuse angle, in order to make the first and second vertical frames 23, 24 parallel to the door stiles 33, 43, the height position of the door rollers 37, 47 on the first vertical frame 23 side relative to the bottom stiles 32, 42 of each shoji screen 3, 4 is adjusted to be lower than the height position of the door rollers 37, 47 on the second vertical frame 24 side.

[0031] The distances G1, G2 between the first and second shoji side receiving portions 62A, 62B and the first and second frame side receiving portions 72A, 72B are set to a size such that the first and second shoji side receiving portions 62A, 62B do not come into contact with the first and second frame side receiving portions 72A, 72B when the shoji screens 3, 4 are in the closed state, including the state in which the shoji screens 3, 4 are tilted to their maximum by adjusting the height of the rollers 37, 47. By setting the gaps G1 and G2 in this manner, the airtightness of the sliding window 1 can be ensured while the shoji screens 3 and 4 can be kept closed.

[0032] Next, we will explain the contact state between the first and second stopper members 52A and 52B of the first and second stopper devices 5A and 5B and the first and second shoji side contact surfaces 641A and 641B of the first and second shoji side support members 6A and 6B and the first and second frame side contact surfaces 741A and 741B of the first and second frame side support members 7A and 7B. As shown in Figures 8(A) and (B), the first and second stopper members 52A and 52B are formed so that their tip ends are thinner than their base ends when viewed from the center of the projection direction of the window frame 2. 8(A), when the first stopper member 52A is in the operating state, a right-angled triangular contact area 641A1 on the first shoji-side contact surface 641A may contact the first stopper member 52A, and a substantially trapezoidal contact area 741A1 on the first frame-side contact surface 741A may contact the first stopper member 52A. The length of the contact area 641A1 in the Z-axis direction is slightly shorter than the length of the first shoji-side receiving portion 62A in the Z-axis direction, but the length of the contact area 741A1 in the Z-axis direction is the same as the length of the first frame-side receiving portion 72A in the Z-axis direction. 8(B), when the second stopper member 52B is in the operating state, the trapezoidal contact area 641B1 on the second shoji-side contact surface 641B may contact the second stopper member 52B, and the trapezoidal contact area 741B1 on the second frame-side contact surface 741B may contact the second stopper member 52B. The length in the Z-axis direction of the contact area 641B1 is the same as the length in the Z-axis direction of the second shoji-side receiving portion 62B, and the length in the Z-axis direction of the contact area 741B1 is the same as the length in the Z-axis direction of the second frame-side receiving portion 72B.

[0033] [Variations] Instead of the first and second shoji side receiving portions 62A, 62B, first and second block-shaped shoji side receiving portions having first and second shoji side abutment surfaces 641A, 641B may be provided, and instead of the first and second frame side receiving portions 72A, 72B, first and second block-shaped frame side receiving portions having first and second frame side abutment surfaces 741A, 741B may be provided. Although an example has been given of a configuration in which the first and second shoji side support portions 62A, 62B are fixed to the door frame 33, 43 via the first and second fixing portions 61A, 61B, the first and second shoji side support portions 62A, 62B and the door frame 33, 43 may be formed integrally, or a similar configuration may be applied to the first and second frame side support portions 72A, 72B.

[0034] The first and second shoji side leg pieces 65A, 65B do not have to be provided at the extending tips of the first and second shoji side support pieces 64A, 64B, and the first and second frame side leg pieces 75A, 75B do not have to be provided at the extending tips of the first and second frame side support pieces 74A, 74B. The first and second shoji-side leg pieces 65A, 65B do not have to abut against the bottom parts 331B1, 431A1, and the first and second frame-side leg pieces 75A, 75B do not have to abut against the metal frame materials 231, 241.

[0035] The first shoji-side support member 6A and the first frame-side support member 7A may be positioned so that the first frame-side support portion 72A is positioned higher than the first shoji-side support portion 62A, or the second shoji-side support member 6B and the second frame-side support member 7B may be positioned so that the second frame-side support portion 72B is positioned higher than the second shoji-side support portion 62B. In this case, it is preferable to set the gap G1 so that the first shoji-side support portion 62A and the first frame-side support portion 72A do not come into contact, even if the window frame 2 is deformed, as shown in Figures 7(B) and (C), and to set the gap G2 so that the second shoji-side support portion 62B and the second frame-side support portion 72B do not come into contact. The rollers 37, 47 may be provided on each shoji screen 3, 4 without using the height adjustment mechanisms 37A, 47A, and in this case, the spacing G1, G2 may be set without taking into account deformation of the window frame 2.

[0036] The window frame 2 may be made up of only metal frame material, and the frame 35 of the outer shoji 3 and the frame 45 of the inner shoji 4 may be made up of only metal frame material. Although a sliding window 1 has been exemplified as a fixture equipped with the stopper device, shoji-side receiving portion, and frame-side receiving portion of the present invention, the stopper device, shoji-side receiving portion, and frame-side receiving portion of the present invention may also be applied to a sliding door as a fixture.

[0037] [Summary of the invention] The building fixture of the present invention comprises a frame body, a shoji screen that slides within the frame body, and a stopper member that moves back and forth along the shoji screen's movement path, and is provided with a stopper device on a first vertical frame facing the shoji screen's door sill in the frame body, a shoji screen-side abutment portion provided on the door sill and having a shoji screen-side abutment surface against which the stopper member can abut when in an operating state in which it has advanced into the movement path, and a frame-side abutment portion provided on the first vertical frame and having a frame-side abutment surface against which the stopper member can abut when in the operating state, and the shoji screen-side abutment portion and the frame-side abutment portion are arranged so as to face each other in the vertical direction when the shoji screen is closed. According to the present invention, there is no need to provide a recess in the shoji side receiving portion into which the frame side receiving portion fits when the shoji is closed, so the expected size of the shoji side abutment surface can be made larger compared to a configuration in which the recess is provided.As a result, the impact per unit area received by the shoji side abutment surface when the shoji collides with the stopper member can be reduced, and damage to the shoji side receiving member can be prevented.

[0038] In the building fixture of the present invention, it is preferable that the shoji side receiving portion comprises a shoji side facing piece that faces the frame side receiving portion when in the closed state, and a shoji side receiving piece that has the shoji side abutment surface and extends from the end of the shoji side facing piece on the first vertical frame side in a direction away from the frame side receiving portion, and that the frame side receiving portion comprises a frame side facing piece that faces the shoji side receiving portion when in the closed state, and a frame side receiving piece that has the frame side abutment surface and extends from the end of the frame side facing piece on the door stile side in a direction away from the shoji side receiving portion. According to the present invention, the weight of the shoji side receiving portion and the frame side receiving portion can be reduced, and the amount of material used can be reduced.

[0039] In the building fixture of the present invention, it is preferable that the shoji side support portion has a shoji side leg piece extending from the extended tip of the shoji side support piece toward the door frame, and the frame side support portion has a frame side leg piece extending from the extended tip of the frame side support piece toward the first vertical frame side. According to the present invention, the possibility that users of the fixture will touch the edges of the shoji side receiving portion or the frame side receiving portion can be reduced.

[0040] In the building fixture of the present invention, it is preferable that the shoji side leg piece has its extended tip abutting the door stile, and the frame side leg piece has its extended tip abutting the first vertical frame. According to the present invention, the impact when the shoji-side receiving part collides with the stopper member can be absorbed by the shoji-side leg piece that abuts against the door stile, thereby suppressing deformation of the shoji-side receiving part. Also, the impact when the stopper member collides with the frame-side receiving part can be absorbed by the frame-side leg piece that abuts against the first vertical frame, thereby suppressing deformation of the frame-side receiving part.

[0041] In the building fixture of the present invention, it is preferable that rollers whose height position relative to the bottom frame can be adjusted are provided on both ends of the bottom frame of the shoji screen in the viewing direction, and that the shoji side support portion and the frame side support portion are positioned so that when the shoji screen is tilted to the maximum angle relative to the bottom frame of the frame body by adjusting the height position of the rollers, the shoji side support portion and the frame side support portion do not come into contact with each other when the shoji screen is in the closed state. According to the present invention, if the frame body is deformed so that the first vertical frame is not perpendicular to the bottom frame, in order to ensure the airtightness of the building material, the shoji screen can be tilted so that the first vertical frame and the door stile are parallel by adjusting the height position of the door rollers, and the shoji screen can be closed without the shoji side support part coming into contact with the frame side support part.

[0042] In the building fixture of the present invention, it is preferable that the shoji screens include an inner shoji screen and an outer shoji screen, the stopper device is provided on each of the first vertical frame and the second vertical frame of the frame body, the shoji side receiving portion is provided on each of the door edge frames of the inner shoji screen and the outer shoji screen, and the frame side receiving portion is provided on each of the first vertical frame and the second vertical frame. According to the present invention, damage to the shoji side support member can be prevented when the inner shoji or outer shoji collide with the stopper member. [Explanation of symbols]
