Description

[Technical Field]

[0001] The present invention relates to a fixing structure for a shoji unit fixed to a mullion. [Background Art]

[0002] Conventionally, an indoor window unit arranged on a partition wall that divides an indoor space is known (see Patent Document 1). The indoor window unit (shoji unit) has an opening / closing window arranged at the uppermost stage, and includes a pair of window units in which a FIX window (fixed window) is arranged at a lower stage than the uppermost stage, adjacently arranged on the left and right, and is configured by connecting connecting vertical frames of these left and right adjacent window units to each other. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2019-44435 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] Incidentally, the indoor window unit described in Patent Document 1 is installed in an opening of a partition wall that divides an indoor space. For example, when installing an indoor window unit, there is a case where the indoor window unit is attached to a mullion. In this case, in terms of construction, it is conceivable to incline the fixing screw relative to the mullion in the out-of-plane direction and drive it obliquely. However, since the fixing screw is driven obliquely, the position of the indoor window unit is easily displaced in the out-of-plane direction relative to the mullion, which makes it difficult to improve workability. Further, it is conceivable to attach a separate component to suppress the positional displacement of the indoor window unit, but in this case, the number of components increases, which may increase the labor for construction.

[0005] An object of the present invention is to provide a fixing structure for a shoji unit that can improve workability. [Means for Solving the Problem]

[0006] The fixing structure for a shoji screen unit of the present invention is a fixing structure for a shoji screen unit that divides a space into one space side and the other space side, and fixes the shoji screen unit to a mullion with fixing screws, wherein the shoji screen unit comprises a panel portion and a vertical member that holds the panel portion, the fixing screws are inclined with respect to the in-plane direction of the shoji screen unit, and one of the vertical member and the mullion has a receiving portion that protrudes toward the other so as to be able to receive the other of the vertical member and the mullion in the out-of-plane direction of the shoji screen unit. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a fixing structure for a shoji screen unit that can improve workability. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] [Structure of this embodiment] Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 and 2, the wall structure 1 comprising the fixed structure 10 for the shoji screen unit according to this embodiment has a mullion 6 installed on the wall opening F1 of the interior wall section that divides the interior space of the building into a first space on one side (one space side) and a second space on the other side (the other space side). The shoji screen unit 3A (first shoji screen unit) and the shoji screen unit 3B (second shoji screen unit) are attached to this mullion 6. In this embodiment, the mullion 6 is positioned at the corner of the wall structure 1, and the shoji screen units 3A and 3B are positioned intersecting each other with the mullion 6 in between. In the following explanation, the first direction along the in-plane direction of shoji unit 3A is defined as the X-axis direction, the vertical direction of shoji units 3A and 3B is defined as the Y-axis direction, and the second direction along the in-plane direction of shoji unit 3B is defined as the Z-axis direction. The X, Y, and Z axes are mutually orthogonal. Furthermore, in the X-axis direction, the direction toward the mullion 6 is defined as the X1 direction and the direction away from the mullion 6 is defined as the X2 direction, and in the Z-axis direction, the direction toward the mullion 6 is defined as the Z1 direction and the direction away from the mullion 6 is defined as the Z2 direction.

[0010] The shoji unit 3A consists of a pair of shoji screens 4 arranged horizontally and connected to each other. Each shoji screen 4 has an outer upper frame 41, an outer lower frame 42, and outer vertical frames 43 (vertical members) made of aluminum extruded profiles assembled around its perimeter. A middle rail 44 is stretched across the left and right outer vertical frames 43, and a sliding window 7 is formed on the upper side of the middle rail 44 as an opening window, while a fixed window 8 is formed on the lower side. The pair of shoji screens 4 are connected to each other using the adjacent outer vertical frames 43 as connecting frames. As shown in Figure 4, the shoji unit 3A is attached to the upper surface F2 of the wall opening F1 via a U-shaped upper frame 2 and connecting members 23, and is screwed to the lower surface F3 of the wall opening F1. This shoji unit 3A is installed in the wall opening F1 by suspending it in a sliding manner while sandwiching its outer upper frame 41 between the upper frame 2, fitting a recess 31 formed in its outer lower frame 42 into a positioning plate 32 attached to the lower surface F3, and then screwing the outer lower frame 42 to the lower surface F3 at an angle. The shoji 4 has a horizontal sliding window 7 in the upper section, but this may be replaced with other types of opening windows such as vertical sliding windows or fixed windows, and the lower section has a fixed window 8, but this may be replaced with opening windows such as horizontal sliding windows or vertical sliding windows.

[0011] As shown in Figure 2, the outer vertical frame 43 on the mullion 6 side of the sliding door unit 3A is attached to the mullion 6, and the outer vertical frame 43 on the opposite side is attached to the side F4 of the wall opening F1. As shown in Figure 3(A), in the shoji unit 3A, the outer vertical frame 43 adjacent to the mullion 6 has a first visible surface portion 45 on the first spatial side, a second visible surface portion 46 on the second spatial side, an outer peripheral surface portion 47 on the outer peripheral side, and an inner peripheral surface portion 48 on the inner peripheral side. The second visible surface portion 46 extends further in the X1 direction than the outer peripheral surface portion 47. The outer peripheral surface portion 47 is formed by being divided into a first spatial side and a second spatial side, and has a plurality of extending pieces 471 that extend in the X1 direction. A water-stopping fin 472 is attached to the continuous portion between the outer peripheral surface portion 47 and the first visible surface portion 45. A retaining groove 481 is formed in the inner perimeter surface 48 to hold the rectangular plate-shaped surface material 50, such as a glass panel, of the sash 4. The portion of the retaining groove 481 below the middle rail 44 holds the surface material 50 (lower panel portion) of the fixed window 8 via a gasket or the like. In addition, a sliding window 7 (lower panel portion) is attached to the portion of the inner perimeter surface 48 above the middle rail 44. Furthermore, an opening 482 is formed in the portion of the inner circumferential surface 48 that is on the second space side of the retaining groove 481, and this opening 482 is continuous with the recessed groove 483 formed by the second visible surface 46, the outer circumferential surface 47, and the side portion 481A that forms the retaining groove 481. A cover 482A is fitted over the opening 482. The outer peripheral surface portion 47 that forms the groove portion 483 has a screw receiving portion 51 that receives the head 91 of the fixing screw 9, which will be described later. The screw receiving portion 51 is made thicker than other parts to facilitate the driving of the fixing screws 9. The screw receiving portion 51 also has a head contact surface 52 that is inclined with respect to the Z-axis direction (out-of-plane direction of the sliding door unit 3A) so that it approaches the mullion 6 as it moves from the first space side to the second space side. The head contact surface 52 contacts the seating surface of the head 91 of the fixing screw 9 that is driven into the screw receiving portion 51.

[0012] Furthermore, the shoji screen unit 3B is configured in substantially the same way as the shoji screen unit 3A and is installed in substantially the same way as the shoji screen unit 3A in the wall opening F1, so the same reference numerals are used as appropriate and its explanation is omitted. In the installed state, the shoji screen unit 3B is positioned so that its in-plane direction is perpendicular to the in-plane direction of the shoji screen unit 3A.

[0013] The mullion 6 has a first fixed surface portion 61 to which the outer vertical frame 43 of the shoji unit 3A is fixed by fixing screws 9, a second fixed surface portion 62 which is arranged perpendicular to the first fixed surface portion 61 and to which the outer vertical frame 43 of the shoji unit 3B is fixed by fixing screws 9, a first outer surface portion 63 which is continuous with the first fixed surface portion 61, and a second outer surface portion 64 which is continuous with the second fixed surface portion 62. The edges of the first fixed surface portion 61 and the second fixed surface portion 62 are continuous with each other along the Y-axis direction on the second spatial side. The edges of the first outer surface portion 63 and the second outer surface portion 64 are continuous with each other along the Y-axis direction on the first spatial side.

[0014] The first fixed surface portion 61 has a stepped portion 65 on the first space side and a fixed portion 66 on the second space side. The stepped portion 65 has a bottom portion 651 that is continuous with the first outer surface portion 63 and is aligned with the Z-axis direction, and a side portion 652 that extends from the bottom portion 651 in the X2 direction. The fixing portion 66 is continuous with the side portion 652 and is arranged on the X2 direction side relative to the bottom portion 651. This fixing portion 66 has a screw engagement portion 67 that the shaft portion 92 of the fixing screw 9 is screwed into. The screw engagement portion 67 is formed in a concave shape along the axial direction A of the shaft portion 92 of the fixing screw 9. The screw engagement portion 67 has a pair of side portions 671 and a bottom portion 672. The bottom portion 672 is inclined in the same direction as the head contact surface 52, and is oriented to facilitate screwing of the shaft portion 92 of the fixing screw 9. Here, the fixing screw 9 is inclined obliquely with respect to the X-axis direction such that the position of the tip end of the shaft portion 92 is located on the first space side relative to the position of the head portion 91 of the fixing screw 9. The extending piece portion 471 of the outer vertical stile 43 is in contact with the fixing portion 66 to which the outer vertical stile 43 is screwed and fixed by the fixing screw 9.

[0015] The second fixing surface portion 62 is configured substantially similarly to the first fixing surface portion 61, so the same reference numerals as those for each component of the first fixing surface portion 61 are assigned and description thereof is omitted. In the second fixing surface portion 62, the bottom portion 651 of the stepped portion 65 is continuous with the second outer surface portion 64.

[0016] The first outer surface portion 63 extends in the X2 direction toward the outer vertical stile 43 side relative to the bottom portion 651 of the stepped portion 65 of the first fixing surface portion 61, and at the tip end portion thereof, a receiving portion 68 protruding in the X2 direction is formed, the receiving portion 68 being capable of receiving the outer vertical stile 43 of the shoji unit 3A from the first space side. The receiving portion 68 is arranged on the first space side relative to the fixing screw 9. The receiving portion 68 includes: a receiving part 681 that extends flush along the facing surface of the first outer surface portion 63 and is arranged on the first space side relative to the first facing surface portion 45 of the outer vertical stile 43; and a contact part 682 that extends in the Z2 direction from the base of the receiving part 681 toward the second space side and is in contact with the continuous portion of the outer vertical stile 43 where the first facing surface portion 45 and the outer peripheral depth surface portion 47 are continuous.

[0017] The second outer surface portion 64 is configured substantially similarly to the first outer surface portion 63, and a receiving portion 68 protruding toward the direction Z2 is formed at the tip end portion of the second outer surface portion 64, the receiving portion being capable of receiving the outer stile 43 of the shoji unit 3B from the first space. In this receiving portion 68, the supporting section 681 extends flush along the visible surface of the second outer surface portion 64, and the contact section 682 of the receiving portion 68 extends from the base of the supporting section 681 toward the second space side in the direction X2.

[0018] Hereinafter, a mounting procedure for mounting the shoji units 3A and 3B to the mullion 6 will be described. First, the mullion 6 is arranged at the corner of the wall opening F1, and the upper and lower ends thereof are fixed to the upper surface F2 and the lower surface F3. Next, as shown in Fig. 4, while the shoji unit 3A is suspended into the wall opening F1, the outer stile 43 on the mullion 6 side shown in (B) of Fig. 3 is brought into contact with the first fixing surface portion 61 and pressed against the receiving portion 68 as shown in (A) of Fig. 3. By setting this pressed state, the positioning of the shoji unit 3A relative to the mullion 6 is performed, and subsequently, the fixing screw 9 is screwed into the screw receiving portion 51 and the screw engaging portion 67. For the screwed-in fixing screw 9, while the shaft portion 92 thereof is guided in the axial direction A by the recessed screw engaging portion 67, the seat surface of the head portion 91 abuts against the head contact surface 52 of the screw receiving portion 51. In this way, the fixing screw 9 is screwed obliquely in the axial direction A toward the first space side where the receiving portion 68 is located, so the outer stile 43 is fixed to the mullion 6 while being kept pressed against the receiving portion 68. In this way, the fixing structure 10 for the shoji unit 3A to the mullion 6 is configured. In the shoji unit 3A, the outer upper rail 41 is fixed to the upper surface F2 of the wall opening F1 via the connecting member 23 or the like, the outer lower rail 42 is screwed to the lower surface F3, and the outer stile 43 on the side surface F4 side is screwed to the side surface F4.

[0019] Meanwhile, the shoji screen unit 3B is suspended from the wall opening F1 in substantially the same manner as the shoji screen unit 3A, and its outer vertical frame 43 is pressed against the receiving portion 68 on the second fixing surface portion 62 of the mullion 6, while the fixing screws 9 are screwed diagonally into the screw receiving portion 51 and the screw threading portion 67 as described above. In this embodiment, the position where the imaginary line along the axial direction A of the fixing screws 9 that fix the outer vertical frame 43 of the shoji screen unit 3B to the second fixing surface portion 62 of the mullion 6 intersects with the imaginary line along the axial direction A of the fixing screws 9 that fix the outer vertical frame 43 of the shoji screen unit 3A to the first fixing surface portion 61 of the mullion 6 is the center position along the Y-axis direction of the mullion 6. In this way, the fixing structure 10 for the mullion 6 of the shoji unit 3B is constructed. In the shoji unit 3B, the outer upper frame 41 is fixed to the upper surface F2 of the wall opening F1 via a connecting member 23, the outer lower frame 42 is screwed to the lower surface F3, and the outer vertical frame 43 on the side F4 is screwed to the side F4.

[0020] [Differentiation] In the above embodiment, a receiving portion 68 is formed on the mullion 6, but it is not limited to the mullion 6; for example, as shown in Figure 5, a receiving portion 70 may be formed on the outer vertical frame 43 (vertical member). In the modified example shown in Figure 5, the fixing screw 9 that secures the shoji unit 3A to the mullion 6 is inclined with respect to the X-axis direction such that the tip of its shaft portion 92 is located on the second space side than the position of its head portion 91. The first visible surface portion 45 on the first space side of the outer vertical frame 43 forms a receiving portion 70 that protrudes in the X1 direction toward the mullion 6 so that the mullion 6 can be received from the first space side. In other words, this receiving portion 70 is configured to be received by the mullion 6 from the second space side. The first fixing surface portion 61 of the mullion 6 has a stepped portion 75 that abuts against the receiving portion 70 in the Z-axis direction. Therefore, it is easy to screw in the fixing screw 9 while pressing the receiving portion 70 against the mullion 6. Furthermore, the fixing screw 9 that secures the shoji unit 3B to the mullion 6 is inclined with respect to the Z-axis direction such that the tip of its shaft portion 92 is located on the second space side than the position of its head portion 91, and the first visible surface portion 45 on the first space side of the outer vertical frame 43 protrudes toward the mullion 6 in the Z1 direction so that it can receive the mullion 6 from the first space side. In other words, this receiving portion 70 is configured to be received by the mullion 6 from the second space side. Note that the second fixing surface portion 62 of the mullion 6 has a stepped portion 75 that abuts against the receiving portion 70 in the X-axis direction. For this reason, it is easy to screw in the fixing screw 9 while pressing the receiving portion 70 against the mullion 6.

[0021] In the above embodiment, the receiving portion 68 is formed flush with the visible surface of the mullion 6, but the receiving portion 68 may be formed at a different position out of plane from the visible surface. Also, when the receiving portion 70 is formed on the outer vertical frame 43, the receiving portion 70 may be formed flush with the visible surface of the outer vertical frame 43, or the receiving portion 70 may be formed at a different position out of plane from the visible surface. In the above embodiment, the screw receiving portion 51 is configured as a groove portion 483 so that the fixing screw 9 is not visible from the outside. However, the invention is not limited to this configuration, and the fixing screw 9 may be provided at a position away from the portion that constitutes the groove portion 483, or the groove portion 483 itself may be omitted. In the above embodiment, the mullion 6 has a first fixed surface portion 61 and a second fixed surface portion 62 that are arranged to intersect each other. However, if only one of the sliding door units 3A or 3B is installed, the screw thread portion 67 of either the first fixed surface portion 61 or the second fixed surface portion 62 may be omitted. In the above embodiment, the mullion 6 is positioned at the corner of the wall opening F1. However, if there is no corner, the mullion 6 may be provided at the positions where the sliding door units 3A and 3B are positioned to the left and right. In this case, the first fixing surface portion 61 and the second fixing surface portion 62 of the mullion 6 are not continuous with each other and are positioned opposite each other to the left and right. Each fixing screw 9 is positioned with its shaft tip inclined toward either the first space side or the second space side. In the above embodiment, the sash units 3A and 3B are constructed by connecting a pair of sashes 4, the upper section of which forms a horizontal sliding window 7 and the lower section of which forms a fixed window 8. However, the invention is not limited to this configuration, and only one of the pair of sashes 4 may be present, or the middle rail 44 may be omitted to form a single panel section, or other types of opening and closing windows such as vertical sliding windows or fixed windows may be provided as panel sections. In the above embodiment, the shoji units 3A and 3B are used to constitute an interior window that partitions the interior space, but they may also be used as windows installed in a building wall that separates the interior from the exterior.

[0022] [Summary of the invention] (1) The fixing structure for a shoji screen unit of the present invention is a fixing structure for a shoji screen unit that divides a space into one space side and the other space side, and fixes the shoji screen unit to a mullion with fixing screws, wherein the shoji screen unit comprises a panel part and a vertical member that holds the panel part, the fixing screws are inclined with respect to the in-plane direction of the shoji screen unit, and one of the vertical member and the mullion has a receiving part that protrudes toward the other so as to be able to receive the other of the vertical member and the mullion in the out-of-plane direction of the shoji screen unit. According to the present invention, by screwing in a fixing screw while receiving the other of the vertical members and mullions in the out-of-plane direction of the shoji screen unit, the fixing screw can be screwed in while positioning the other of the vertical members and mullions relative to the other. Furthermore, by screwing in the fixing screw at an angle along a direction inclined with respect to the in-plane direction of the shoji screen unit, the vertical members and mullions can be fixed in a state where misalignment between them is unlikely to occur. This improves the ease of installation of the shoji screen unit. (2) In the fixing structure of the shoji unit of the present invention, the position of the tip of the shaft of the fixing screw is positioned on the side of the space that is closer to With this configuration, by pressing the vertical member against the receiving part from one side of the space and screwing the fixing screw diagonally into the vertical member and the mullion so that it is inclined toward the one side of the space, the fixing screw can be screwed in while maintaining the position of the vertical member out of plane relative to the mullion, thereby improving workability. (3) In the fixing structure of the shoji unit of the present invention, the receiving portion may be formed along the visible surface of one of the vertical members and the mullions. With this configuration, even if the receiving part is exposed, the receiving part can be made to form part of the visible surface of one of the vertical members or mullions, thus improving the aesthetic appearance. (4) In the fixing structure of the shoji unit of the present invention, the vertical member has a screw receiving portion for receiving the head of the fixing screw, the mullion has a screw threading portion into which the shaft of the fixing screw is screwed, the screw receiving portion is inclined with respect to the out-of-plane direction of the shoji unit so as it moves from the one space side toward the other space side and has a head contact surface that contacts the head of the fixing screw, and the screw threading portion may be formed in a concave shape along the axial direction of the shaft of the fixing screw. With this configuration, the concave screw threading portion of the mullion can guide the shaft of the fixing screw in the axial direction, making it easy to orient it in a predetermined inclination direction. Furthermore, the head contact surface of the screw receiving portion of the vertical member contacts the head of the fixing screw, allowing the fixing screw to be tightened while its axial direction is aligned in a predetermined inclination direction. As a result, the orientation of the fixing screw does not deviate from its predetermined orientation, and the vertical member can be fixed to the mullion in a predetermined position. (5) In the fixing structure of the shoji screen unit of the present invention, a recessed groove is formed in the vertical member, a screw receiving portion is formed in the recessed groove to receive the head of the fixing screw, and a cover may be attached to the recessed groove. This configuration allows the screw receiving portion to be concealed from external view, thereby improving the aesthetic appeal. (6) In the fixing structure of the shoji screen unit of the present invention, the shoji screen unit comprises a first shoji screen unit and a second shoji screen unit, and the mullion may have a first fixing surface portion to which the vertical members of the first shoji screen unit are fixed by the fixing screws, and a second fixing surface portion which is arranged intersecting the first fixing surface portion and to which the vertical members of the second shoji screen unit are fixed by the fixing screws. With this configuration, the vertical members of the first shoji unit are positioned adjacent to the first fixed surface, and the vertical members of the second shoji unit are positioned adjacent to the second fixed surface. By pressing the other of these vertical members and mullions against a receiving portion formed on one of them, and driving each fixing screw from the common other space toward the one space, the workability can be improved.
