Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, there is known a fitting in which the upper and lower parts of a shoji screen are stored and supported in a Kendon style in rail grooves provided in the upper and lower frames, and the shoji screen is not supported by the left and right vertical frames (see, for example, Patent Document 1). In this fitting, a stopper member that protrudes into the rail groove of the lower frame is provided at the fixed part of the handle of the lower rail of the shoji screen to prevent the shoji screen from coming off the lower frame when it is lifted up due to vertical shaking caused by an earthquake. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-184709 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventor further investigated other causes of the shoji screen coming off the frame, other than the case where it comes off the lower frame due to vertical shaking caused by an earthquake. As a result, it was found that if the lower frame is bent due to poor construction of the frame, the shoji screen may move downward, releasing the engagement between the shoji screen and the upper frame, causing the shoji screen to come off the frame.

[0005] Furthermore, because direct sunlight generally shines on fittings from outside the room and penetrates primarily around the lower periphery of the fittings, thermal deformation can occur, causing the lower rail of a shoji screen to shrink in the viewing direction. Furthermore, when the heat of direct sunlight softens the lower rail, the weight of the glass and other surface materials contained within the shoji screen can cause the lower rail to bend, deforming the screen and reducing its vertical dimension. When the vertical dimension of the shoji screen decreases, the position of the upper rail of the shoji screen drops, changing the engagement between the screen and the frame, which can cause the screen to rattle or come off the frame.

[0006] Therefore, the inventor discovered the problem of preventing the shoji from coming off the frame by maintaining the engagement between the shoji and the upper frame even if the shoji moves downward or the position of the upper rail of the shoji drops. [Means for solving the problem]

[0007] The building fixture disclosed herein comprises a frame body having an upper frame, a lower frame, and left and right vertical frames, with grooves in each of the upper and lower frames; a shoji screen having a face material on the inside of a frame body having upper slats, lower slats, and left and right vertical frames, and held in the upper and lower frames by having its upper and lower ends inserted into the grooves, respectively; and an upper anti-detachment member that protrudes upward from the upper end surface of the shoji screen and prevents the shoji screen from coming off the upper frame, the upper anti-detachment member extending along the length of the upper slats and having a rib that protrudes upward so as to fit into the space between the upper end surface of the shoji screen and the inner bottom surface of the groove when the upper end of the shoji screen is inserted diagonally upward into the groove of the upper frame.

[0009] Each embodiment of the fittings of the present disclosure will be described in detail below with reference to the drawings. The fittings in the embodiments are shown as a fixed window 1. The fixed window 1 is a so-called fixed window, and is attached to the inside of a frame 101 provided along the inner periphery of a rectangular opening 100 in the building frame. The fixed window 1 does not open or close the opening 100 except when the shoji screen 3 is removed for cleaning or the like.

[0010] FIG. 1 is a front view of a fixed window 1 as seen from the indoor side. In the following figures, the X1 direction indicates the outdoor side of the fixed window 1, and the X2 direction indicates the indoor side of the fixed window 1. Another window (not shown), such as a fixed window or sliding window, may be attached inside the frame 101 on the outdoor side of the fixed window 1. This creates a double-glazed window inside the frame 101, further improving thermal insulation and soundproofing. The fixed window 1 of this embodiment can be retrofitted to the indoor side of an existing window (not shown).

[0011] The fixed window 1 comprises a frame 2 provided inside the frame 101, a shoji screen 3 housed inside the frame 2, a lower stop member 4, and an upper stop member 5. The frame 2 is formed by framing an upper frame 21, a lower frame 22, and left and right vertical frames 23, 23 in a rectangular shape. The shoji screen 3 is removably fitted inside the frame 2. The lower stop member 4 and upper stop member 5 are both members that prevent the shoji screen 3 from coming off the frame 2.

[0012] The upper frame 21 of the frame body 2 is integrally extruded from a resin material. The upper frame 21 has a first hollow portion 211 with a rectangular cross-section and hollow structure located on the outdoor side, a second hollow portion 212 with a rectangular cross-section and hollow structure located on the indoor side, and a flat base portion 213 that connects the upper ends of the first hollow portion 211 and the second hollow portion 212. The first hollow portion 211, the second hollow portion 212, and the base portion 213 extend over the entire length of the upper frame 21 in the extension direction. The first hollow portion 211 and the second hollow portion 212 protrude downward from the base portion 213 at the same height.

[0013] The first hollow portion 211 and the second hollow portion 212 are arranged parallel to each other and spaced apart in the indoor / outdoor direction. As a result, a groove portion 214 is formed between the first hollow portion 211, the second hollow portion 212 and the base portion 213, spanning the entire length of the upper frame 21 in the extension direction. The groove portion 214 is open downward and accommodates the upper end of the shoji screen 3. The base portion 213 forms the inner bottom surface of the groove portion 214.

[0014] The lower end of the first hollow portion 211 is provided with a sealing portion 215 that protrudes toward the inside of the room and elastically contacts the outside surface of the shoji screen 3. The lower end of the second hollow portion 212 is provided with a fin portion 216 that protrudes toward the outside of the room and elastically contacts the inside surface of the shoji screen 3. The upper frame 21 is fixed to the upper inner surface of the frame 101 with screws (not shown) that pass through the base portion 213.

[0015] The lower frame 22 of the frame body 2 is integrally extruded from a resin material. The lower frame 22 has a first hollow portion 221 having a hollow structure with a rectangular cross section and located on the outdoor side, a second hollow portion 222 having a hollow structure with a rectangular cross section and located on the indoor side, and a flat base portion 223 connecting the lower ends of the first hollow portion 221 and the second hollow portion 222. The first hollow portion 221, the second hollow portion 222, and the base portion 223 extend over the entire length of the extension direction of the lower frame 22. In this embodiment, the first hollow portion 221 and the second hollow portion 222 protrude upward from the base portion 223 at the same height, but they do not necessarily have to protrude at the same height.

[0016] The first hollow portion 221 and the second hollow portion 222 are arranged parallel to each other and spaced apart in the indoor / outdoor direction. As a result, a groove portion 224 is formed between the first hollow portion 221, the second hollow portion 222 and the base portion 223, spanning the entire length of the lower frame 22 in the extension direction, similar to the upper frame 21. The groove portion 224 opens upward and accommodates the lower end of the shoji screen 3. The base portion 223 forms the inner bottom surface of the groove portion 224.

[0017] A sealing portion 225 is integrally formed at the upper end of the first hollow portion 221, protruding toward the inside of the room and elastically contacting the outside surface of the shoji screen 3. A fin portion 226 is integrally formed at the upper end of the second hollow portion 222, protruding toward the outside of the room and elastically contacting the inside surface of the shoji screen 3. The lower frame 22 is fixed to the lower inner surface of the frame 101 by screws (not shown) that pass through the base portion 223.

[0018] 2, a plurality of resin liners 227 that support the lower end of the shoji screen 3 are provided at predetermined intervals inside the groove 224 of the lower frame 22. The liners 227 are formed in a block shape and have a height slightly lower than the height of the first hollow portion 221 and the second hollow portion 222 of the lower frame 22. Therefore, the lower end surface of the shoji screen 3 accommodated in the groove 224 of the lower frame 22 is placed on the upper surface of the liners 227, and is positioned slightly lower than the upper end surfaces of the first hollow portion 221 and the second hollow portion 222 of the lower frame 22.

[0019] The vertical frames 23 of the frame body 2 are each integrally extruded from a resin material into a substantially L-shape. The vertical frames 23 extend vertically between the upper frame 21 and the lower frame 22. The vertical frames 23 have base portions 231 extending a predetermined width along the vertical direction of the frame 101, exterior wall portions 232 extending at a substantially right angle from the exterior ends of the base portions 231 toward the inside of the frame 101, and abutment pieces 233 extending at a substantially right angle from the interior ends of the exterior wall portions 232 toward the interior.

[0020] The contact pieces 233, 233 are formed narrower than the base plate parts 231, 241 so as to come into contact with the exterior surface of the shoji screen 3. Sealing parts 234, 234 that elastically come into contact with the exterior surface of the shoji screen 3 are integrally formed at the tips of the contact pieces 233, 233. The vertical frames 23, 23 are fixed to the inner surfaces of the left and right sides of the frame 101 by screws (not shown) that pass through the base plate parts 231, 231, respectively.

[0021] The shoji screen 3 is constructed by fitting a surface material 34 such as glass through a glazing channel 341 inside a rectangular frame body 30 made up of an upper frame 31, a lower frame 32, and left and right vertical frames 33, 33. The surface material may be double-glazed glass made up of two sheets of glass. In the case of double-glazed glass, it is held in place by a retaining member made of soft PVC attached to the frame body.

[0022] As shown in Fig. 2, the upper and lower crosspieces 31 and 32 are each made up of a metal core 311, 321, resin cover materials 312, 322 that cover the outside and inside surfaces of the core, and resin upper and lower cover materials 313 and 323 that are attached to the upper and lower end surfaces of the resin cover materials 312, 322. As shown in Figs. 3 and 5, the vertical stiles 33, 33 are each made up of a metal core 331, 331, resin cover materials 332, 332 that cover the outside of the core, and end cover materials 333, 333 (see Fig. 5) that cover the upper and lower end surfaces of the vertical stiles 33, 33, respectively.

[0023] As shown in FIG. 1, the shoji screen 3 has a vertically-hung structure in which an upper sash 31 and a lower sash 32 are arranged between left and right vertical frames 33. Specifically, the left and right vertical frames 33 extend over the entire length of the shoji screen 3 in the vertical direction. The upper sash 31 and the lower sash 32 are arranged between the left and right vertical frames 33, and connect the upper ends and lower ends of the vertical frames 33, respectively. End cover materials 333 on the upper and lower end faces of the vertical frames 33 are arranged flush with the upper end cover material 313 of the upper sash 31 and the lower end cover material 323 of the lower sash 32, respectively. A roughly U-shaped handle 35 is attached to the center of the interior-facing surface of the lower sash 32.

[0024] The lower anti-slip member 4 is the same member as the conventional one, and is positioned between one of the pair of bases 351, 351 of the handle 35 and the interior side surface 32a of the lower rail 32 of the shoji screen 3, as shown in Figures 1, 2 and 4.

[0025] As shown in FIG. 4 , the lower retaining member 4 includes a retaining portion 41, which is a vertically elongated rectangular metal or resin case; a locking tongue 42 made of a metal plate housed inside the retaining portion 41; and a vertically elongated hole 43 that penetrates from the retaining portion 41 to the locking tongue 42. The locking tongue 42 is formed as a long plate that is longer in the vertical direction than the retaining portion 41. Approximately the upper half of the locking tongue 42 is inserted into the retaining portion 41. Approximately the lower half of the locking tongue 42 protrudes from the retaining portion 41 into the groove 224 of the lower frame 22. Because the upper end surface 41 a of the retaining portion 41 is closed, the locking tongue 42 inside the retaining portion 41 does not move upward. The corners of the locking tongue 42 protruding from the retaining portion 41 are rounded.

[0026] The lower retaining member 4 is attached to the indoor surface 32a of the lower rail 32 with a fixing screw 44. More specifically, the lower retaining member 4 is positioned between the indoor surface 32a of the lower rail 32 of the shoji screen 3 before it is attached to the frame 2 and the base 351 of the handle 35. The lower retaining member 4 is temporarily fixed by loosely fitting the fixing screw 44 that attaches the base 351 into the screw insertion hole of the base 351. At this time, the lower retaining member 4 has been moved upward so that the shank 431 of the fixing screw 44 is positioned at the lower end of the elongated hole 43 so as not to interfere with the insertion of the lower end of the shoji screen 3 into the groove 224 of the bottom frame 22. Therefore, the lower retaining member 4 is temporarily fixed in a position higher than the final installation position.

[0027] As will be described later, after the shoji screen 3 is fitted into the frame body 2 using the Kendon method, the lower anti-detachment member 4 is slid downward along the elongated hole 43. As a result, the locking tongue 42 is inserted into the groove 224 of the lower frame 22 through the gap between the second hollow portion 222 of the lower frame 22 and the lower rail 32 of the shoji screen 3, as shown in FIG. 2 . The locking tongue 42 in the groove 224 protrudes downward beyond the lower-end cover material 323 of the lower rail 32 of the shoji screen 3 and is positioned between the liner 227 and the second hollow portion 222 of the lower frame 22. The lower end 42a of the locking tongue 42 is close to the base portion 223 of the lower frame 22. Then, by tightening the fixing screw 44, the lower anti-detachment member 4 is sandwiched between the lower rail 32 and the base 351 of the handle 35 and fixed to the lower rail 32. Since the shaft 431 of the fixing screw 44 is disposed at the upper end of the elongated hole 43, the locking tongue 42 in the holding portion 41 does not move downward.

[0028] By attaching the lower stopper member 4 to the lower rail 32 of the shoji screen 3, even if the shoji screen 3 moves upward due to vertical shaking caused by an earthquake, the locking tongue 42 remains engaged with the groove 224 of the lower frame 22. This prevents the lower end of the shoji screen 3 from coming off the lower frame 22.

[0029] Next, the upper anti-slip member 5 will be described with reference to Figures 1, 2 and 5. The upper anti-slip member 5 is placed on the upper end surface of the shoji screen 3 and protrudes upward. In this embodiment, the upper anti-slip member 5 is made of resin end cover material 333 attached to the upper end surfaces of the vertical stiles 33, 33. The end cover material 333 is a member that connects the vertical stile 33 and the upper rail 31. The upper anti-slip member 5 made of the end cover material 333 is attached to the upper end surface of the vertical stile 33 by means of mounting legs 333b.

[0030] The upper anti-detachment member 5 has ribs 51a and 51b made of hard resin and formed integrally with the upper surface 333a of the end cover material 333. The ribs 51a and 51b extend parallel to the length of the upper rail 31 of the shoji screen 3 on the upper surface 333a of the end cover material 333, and protrude to a predetermined protruding height H1. The upper surface 333a of the end cover material 333 is the upper end surface of the shoji screen 3. The rib 51a is positioned adjacent to the outer edge 333c of the upper surface 333a of the end cover material 333, and the rib 51b is positioned adjacent to the inner edge 333d of the upper surface 333a of the end cover material 333. The two ribs 51a and 51b protrude to the same height. This upper anti-slip member 5 is formed integrally with the end cover material 333 of the vertical frame 33, so it is low cost, and the upper anti-slip member 5 can be easily installed on the shoji screen 3 by simply attaching the end cover material 333 to the vertical frame 33.

[0031] Next, we will explain how to insert the shoji screen 3 into the frame body 2 using the Kendon method. As shown in Figure 6, the shoji screen 3 is inserted into the groove 214 of the upper frame 21 and the groove 224 of the lower frame 22 using the Kendon method from the inside of the room. That is, first, with the upper end of the shoji screen 3 tilted toward the outside of the room, the upper end of the shoji screen 3 is inserted diagonally upward deep into the groove 214 of the upper frame 21.

[0032] When the shoji screen 3 is inserted deep into the groove 214, as shown in Figure 7, a triangular space S is formed between the top end surface of the shoji screen 3 and the base plate 213, which is the inner bottom surface of the groove 214, with the outside of the room being higher and the inside being lower. The ribs 5a1 and 51b of the upper anti-detachment member 5 protrude from the upper surface 333a of the end cover material 333 so as to fit within this space S. More specifically, the rib 51b, which is located on the indoor side where the height of the space S is lower, protrudes from the upper surface 333a of the end cover material 333 so as to fit within the space S.

[0033] Being contained within the space S means that the ribs 51a and 51b protrude to an extent that they do not interfere with the base plate 213 and cause problems when inserting the upper end of the shoji screen 3 into the groove 214. The tips of the ribs 51a and 51b may come into contact with the base plate 213 as long as they do not cause problems when inserting the shoji screen 3.

[0034] After inserting the upper end of the shoji screen 3 into the groove 214, the lower end of the shoji screen 3 is moved toward the outside of the room and aligned with the groove 224 of the lower frame 22. Then, the shoji screen 3 is lowered and the lower end of the shoji screen 3 is inserted into the groove 224 of the lower frame 22. As a result, the upper and lower ends of the shoji screen 3 are accommodated in the grooves 214, 224, respectively, and the shoji screen 3 is fitted and held in place between the upper frame 21 and the lower frame 22. The vertical frames 23, 23 abut the sealing portions 234, 234 against the vertical stiles 33, 33 of the shoji screen 3 from the outside of the room, thereby regulating the position of the shoji screen 3 on the outside. The vertical frames 23, 23 only abut the sealing portions 234, 234 against the outside surface of the shoji screen 3, and do not hold the shoji screen 3. The sealing portion 215 and fin portion 216 of the upper frame 21 abut against the upper end of the shoji screen 3 from the outside and inside of the room, respectively, thereby ensuring airtightness, preventing the upper end of the shoji screen 3 from rattling, and blocking the intrusion of dust and other foreign matter from outside. The sealing portion 225 and fin portion 226 of the lower frame 22 abut against the lower end of the shoji screen 3 from the outside and inside of the room, respectively, thereby ensuring airtightness, preventing the lower end of the shoji screen 3 from rattling, and blocking the intrusion of dust and other foreign matter from outside.

[0035] When the shoji screen 3 is attached to the frame 2, the upper end of the shoji screen 3 engages the upper frame 21 more firmly by the protruding height H1 of the ribs 51a, 51b of the upper anti-detachment member 5, as shown in Figure 2. Therefore, even if the shoji screen 3 moves downward or the position of the upper rail 31 of the shoji screen 3 drops, the engagement between the groove 214 and the shoji screen 3 is maintained by the protruding height H1 of the ribs 51a, 51b, preventing the shoji screen 3 from coming off the frame 2. The ribs 51a, 51b have a height that allows them to fit into the space S between the upper end face of the shoji screen 3 inserted deep into the groove 214 and the base plate 213 inside the groove 214, so the ribs 51a, 51b do not interfere with the insertion of the shoji screen 3 into the upper frame 21.

[0036] The protruding heights of the two ribs 51a, 51b of the upper anti-detachment member 5 may be different, as shown in Fig. 8. In the upper anti-detachment member 5 shown in Fig. 8, the protruding height H2 of the rib 51a on the outside of the room is higher than the protruding height H1 of the rib 51b on the inside of the room. This is because, as shown in Fig. 9, when the upper end of the shoji screen 3 is inserted obliquely upward into the groove 214 of the upper frame 21, the rib 51a on the outside of the room is positioned on the higher side of the space S. The protruding height H2 of the rib 51a on the outside of the room can be made larger than the rib 51b on the inside of the room, which further increases the engagement of the upper end of the shoji screen 3 with the upper frame 21. As a result, the shoji screen 3 can be more effectively prevented from coming off the frame 2.

[0037] The upper anti-slip member 5 can also be provided on the upper rail 31 of the shoji screen 3, as shown in Fig. 10. The upper anti-slip member 5 shown in Fig. 10 has a base plate 52 fixed to the upper surface 313a of the upper end cover material 313 of the upper rail 31 with screws 53. The upper surface 313a of the upper end cover material 313 is the upper end surface of the shoji screen 3. The ribs 51a and 51b are formed integrally with the upper surface of the base plate 52. The outdoor rib 51a is located close to the outdoor edge 313b of the upper surface 313a of the upper end cover material 313.

[0038] 10 can be provided on the upper surface 313a of the upper end cover material 313 at intervals in the longitudinal direction of the upper crosspiece 31. The ribs 51a, 51b and the base plate 52 may be formed over the entire length of the upper crosspiece 31. The ribs 51a, 51b may be formed integrally with the upper surface 313a of the upper end cover material 313, similar to when the ribs 51a, 51b are provided on the end cover material 333 of the vertical stile 33.

[0039] The number of ribs on the upper retaining member 5 is not limited to two, one on the outside and one on the inside of the room. At least one rib needs to be placed near the outside edge 313b, 333c of the upper end surface of the shoji screen 3.

[0040] In summary, the fixed window 1, which is a fixture of this embodiment, has the following effects: The fixed window 1 comprises a frame body 2 having an upper frame 21, a lower frame 22, and left and right vertical frames 23, 23, with grooves 214, 224 in the upper frame 21 and lower frame 22, respectively, a shoji screen 3 having an upper rail 31, a lower rail 32, and left and right vertical stiles 33, 33, with a face material 34 attached to the inside of the frame body 30, and whose upper and lower ends are inserted into the grooves 214, 224, respectively, to be held in the upper frame 21 and lower frame 22, and an upper stopper member 5 that protrudes upward from the upper end surface of the shoji screen 3 and prevents the shoji screen 3 from coming off the upper frame 21. The upper anti-slip member 5 extends along the length of the upper crosspiece 31 and has ribs 51a, 51b that protrude upward so as to fit into the space S between the upper end surface of the shoji screen 3 and the base plate 213, which is the inner bottom surface of the groove 214, when the upper end of the shoji screen 3 is inserted obliquely upward into the groove 214 of the upper frame 21. As a result, the engagement with the upper frame 21 is increased by the protruding height of the ribs 51a, 51b of the upper anti-slip member 5, so that even if the shoji screen 3 moves downward or the position of the upper crosspiece 31 of the shoji screen 3 drops, the engagement between the groove 214 and the shoji screen 3 is maintained by the protruding height of the ribs 51a, 51b, and the shoji screen 3 is prevented from coming off the frame body 2. The ribs 51a and 51b have a height that allows them to fit into the space S between the upper end surface of the shoji screen 3 inserted deep into the groove 214 and the base plate 213 within the groove 214, so that the ribs 51a and 51b do not interfere with the insertion of the shoji screen 3 into the upper frame 21.

[0041] When the ribs are positioned close to at least the outer edges 313b, 333c of the upper end surface of the shoji screen 3, the protruding height of the ribs can be increased, which further increases the grip of the upper end of the shoji screen 3 against the upper frame 21. As a result, the shoji screen 3 can be more effectively prevented from coming off the frame body 2.

[0042] When the ribs are provided on the upper end cover material 313 and the end cover material 333 that form the upper end surface of the shoji screen 3, the upper anti-detachment member 5 can be easily provided on the shoji screen 3 simply by attaching the upper end cover material 313 and the end cover material 333.
