Description

Technical Field

[0001] The present disclosure relates to a fitting.

Background Art

[0002] Conventionally, there has been known a fitting in which the upper and lower portions of a shoji screen are stored and supported in a kendon manner in rail grooves provided in an upper frame and a lower frame, and the shoji screen is not supported by the left and right vertical frames (see, for example, Patent Document 1). In this fitting, in order to prevent the shoji screen from coming off the lower frame when the shoji screen floats upward due to vertical shaking during an earthquake, a detachment prevention member that protrudes toward the rail groove of the lower frame is provided at the fixing portion of the handle of the lower rail of the shoji screen.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor further examined the cause of the shoji screen coming off the frame body other than when the shoji screen comes off the lower frame due to vertical shaking during an earthquake. As a result, it was found that when the lower frame is bent due to poor construction of the frame body or the like, the shoji screen may move downward and the engagement between the shoji screen and the upper frame may be released, and the shoji screen may come off the frame body.

[0005] Furthermore, generally, since direct sunlight irradiated on the fitting from the outdoor side is mostly incident on the periphery of the lower part of the fitting, thermal deformation may occur in which the lower rail of the shoji screen contracts in the viewing direction. Also, when the lower rail softens due to the heat of direct sunlight, the lower rail may bend due to the weight of the facing material such as glass stored in the shoji screen, and the shoji screen may be deformed, and the vertical dimension of the shoji screen may become smaller. When the vertical dimension of the shoji screen becomes smaller, the position of the upper rail of the shoji screen drops, and the engagement state between the shoji screen and the frame body may change, and there is a risk that the shoji screen may rattle or come off the frame body.

[0006] Therefore, the inventor has found a problem of preventing the shoji from coming off the frame by enabling the engagement state between the shoji and the upper frame to be maintained not only when the shoji moves upward but also when it moves downward or the position of the upper rail of the shoji drops.

Means for Solving the Problem

[0007] The fitting of the present disclosure includes a frame body having an upper frame, a lower frame, and left and right vertical frames, each having a groove portion in the upper frame and the lower frame, a face material inside a frame body having an upper rail, a lower rail, and left and right vertical rails, and the shoji is held by the upper frame and the lower frame by inserting the upper end portion and the lower end portion into the groove portions respectively, and a detachment prevention member provided on the frame body for preventing the shoji from coming off the frame body. The detachment prevention member includes a locking piece disposed on the outdoor side of the shoji and provided so as to be lockable to the frame body, and an operation member for rotationally moving the locking piece between a locking position and a locking release position, and is a fitting.

Mode for Carrying Out the Invention

[0009] Hereinafter, each embodiment of the fitting of the present disclosure will be described in detail with reference to the drawings. The fitting in the embodiment shows a FIX window 1. The FIX window 1 is a so-called fixed window and is attached inside a frame 101 provided along the inner circumference of a rectangular opening 100 of a building body. The FIX window 1 does not open or close the opening 100 except when the shoji 3 is removed for cleaning or the like.

[0010] FIG. 1 is a front view of the FIX window 1 as viewed from the indoor side. In the drawings shown below, the X1 direction indicates the outdoor side of the FIX window 1, and the X2 direction indicates the indoor side of the FIX window 1. Other windows (not shown) such as FIX windows and sliding windows may be further attached inside the frame 101 on the outdoor side of the FIX window 1. Thereby, a double window is constructed inside the frame 101, and the heat insulation and sound insulation are further improved. The FIX window 1 of the present embodiment can be retrofitted on the indoor side of an existing window (not shown).

[0011] The FIX window 1 has a frame body 2 provided inside the frame 101, a shoji 3 housed inside the frame body 2, and a detachment prevention member 4. The frame body 2 is configured by framing a top frame 21, a bottom frame 22, and left and right vertical frames 23, 23 in a rectangle. The shoji 3 is removably fitted inside the frame body 2. The detachment prevention member 4 is a member for preventing the shoji 3 from coming off the frame body 2.

[0012] The top frame 21 of the frame body 2 is integrally extruded and formed of a resin material. The top frame 21 has a first hollow portion 211 having a rectangular cross-section arranged on the outdoor side, a second hollow portion 212 having a rectangular cross-section arranged on the indoor side, and a flat plate-like substrate portion 213 connecting the upper end portions of the first hollow portion 211 and the second hollow portion 212. The first hollow portion 211, the second hollow portion 212, and the substrate portion 213 extend over the entire length of the top frame 21 in the extending direction. The first hollow portion 211 and the second hollow portion 212 project downward from the substrate portion 213 at the same height.

[0013] The first hollow portion 211 and the second hollow portion 212 are arranged in parallel at a distance in the indoor-outdoor direction. As a result, a groove portion 214 extending over the entire length in the extending direction of the upper frame 21 is formed between the first hollow portion 211, the second hollow portion 212, and the substrate portion 213. The groove portion 214 opens downward and houses the upper end portion of the shoji 3. The substrate portion 213 constitutes the inner bottom surface of the groove portion 214.

[0014] A sealing portion 215 that protrudes toward the indoor side and elastically contacts the outdoor-side surface of the shoji 3 is provided at the lower end portion of the first hollow portion 211. A fin portion 216 that protrudes toward the outdoor side and elastically contacts the indoor-side surface of the shoji 3 is provided at the lower end portion of the second hollow portion 212. The upper frame 21 is fixed to the upper inner surface of the frame 101 by a screw (not shown) that penetrates the substrate portion 213.

[0015] The lower frame 22 of the frame body 2 is integrally extrusion-molded from a resin material. The lower frame 22 has a first hollow portion 221 having a hollow structure with a rectangular cross-section arranged on the outdoor side, a second hollow portion 222 having a hollow structure with a rectangular cross-section arranged on the indoor side, and a flat plate-shaped substrate portion 223 that connects the lower end portions of the first hollow portion 221 and the second hollow portion 222. The first hollow portion 221, the second hollow portion 222, and the substrate portion 223 extend over the entire length in the extending direction of the lower frame 22. The first hollow portion 221 and the second hollow portion 222 of the present embodiment protrude upward from the substrate 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 in parallel at a distance in the indoor-outdoor direction. As a result, a groove portion 224 extending over the entire length in the extending direction of the lower frame 22 is formed between the first hollow portion 221, the second hollow portion 222, and the substrate portion 223, similar to the upper frame 21. The groove portion 224 opens upward and houses the lower end portion of the shoji 3. The substrate portion 223 constitutes the inner bottom surface of the groove portion 224.

[0017] At the upper end of the first hollow portion 221, a sealing portion 225 that protrudes toward the indoor side and elastically contacts the outdoor surface of the shoji 3 is integrally provided. At the upper end of the second hollow portion 222, a fin portion 226 that protrudes toward the outdoor side and elastically contacts the indoor surface of the shoji 3 is integrally provided. The lower frame 22 is fixed to the lower inner surface of the frame 101 by screws (not shown) that penetrate the substrate portion 223.

[0018] As shown in FIG. 2, inside the groove portion 224 of the lower frame 22, a plurality of resin liners 227 that support the lower end of the shoji 3 are provided at predetermined intervals. The liner 227 is formed in a block shape and has a height slightly lower than the heights 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 3 accommodated in the groove portion 224 of the lower frame 22 is placed on the upper surface of the liner 227 and is arranged at a position 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, 23 of the frame body 2 are integrally extrusion-molded in a substantially L shape by a resin material, respectively. The vertical frames 23, 23 extend vertically between the upper frame 21 and the lower frame 22. The vertical frames 23, 23 include substrate portions 231, 231 that extend in a predetermined width along the vertical direction of the frame 101, outdoor wall portions 232, 232 that extend substantially at a right angle from the outdoor end portions of the substrate portions 231, 231 toward the inside of the frame 101, contact piece portions 233, 233 that extend substantially at a right angle from the inner end portions of the outdoor wall portions 232, 232 toward the indoor side, and locking wall portions 234, 234 that extend outward from the indoor end portions of the contact piece portions 233, 233 toward the substrate portions 231, 231.

[0020] The contact piece portions 233, 233 are formed to be narrower in width than the substrate portions 231, 241 so as to contact the outdoor surface of the shoji 3. The locking wall portions 234, 234 extend substantially parallel to the outdoor wall portions 232, 232. The locking wall portions 234, 234 are arranged at a predetermined interval from the substrate portions 231, 231. A locking groove 235 that can accommodate the locking piece 41 of the detachment prevention member 4 described later is formed between the outdoor wall portions 232, 232 and the locking wall portions 234, 234.

[0021] At the tips of the connecting pieces 233, 233, sealing portions 236, 236 that elastically contact the outdoor-side surface of the shoji 3 are integrally provided respectively. The vertical frames 23, 23 are fixed to the inner surfaces of the left and right side portions of the frame 101 respectively by screws (not shown) that penetrate the substrate portions 231, 231.

[0022] The shoji 3 is configured by housing a facing material 34 such as glass through a glazing channel 341 inside a frame body 30 formed by rectangularly framing an upper rail 31, a lower rail 32, and left and right vertical frames 33, 33. The facing material may be a multi-layer glass composed of two sheets of glass. In the case of multi-layer glass, it is held by a holding member made of soft vinyl chloride provided in the frame body.

[0023] As shown in FIG. 2, the upper rail 31 and the lower rail 32 are each composed of a metal core material 311, 321, resin cover materials 312, 322 that cover the outdoor side and the indoor side thereof, and resin upper cover materials 313 and lower cover materials 323 attached to the upper end surfaces and the lower end surfaces of the resin cover materials 312, 322 respectively. As shown in FIGS. 3 and 5, the vertical frames 33, 33 are each composed of a metal core material 331, 331, resin cover materials 332, 332 that cover the outside thereof, and end cover materials 333 (see FIGS. 7 and 8) that cover the upper and lower end surfaces of the vertical frames 33, 33 respectively.

[0024] As shown in FIG. 1, the shoji 3 has a vertical-lapping structure in which the upper rail 31 and the lower rail 32 are arranged between the left and right vertical frames 33, 33. Specifically, the left and right vertical frames 33, 33 extend over the entire vertical length of the shoji 3. The upper rail 31 and the lower rail 32 are arranged between the left and right vertical frames 33, 33 and connect the upper ends and the lower ends of the vertical frames 33, 33 respectively. The end cover materials 333 on the upper and lower end surfaces of the vertical frames 33, 33 are arranged flush with the upper cover material 313 of the upper rail 31 and the lower cover material 323 of the lower rail 32 respectively. A substantially U-shaped handle 35 is attached to the central portion of the indoor-side surface of the lower rail 32.

[0025] The detachment prevention member 4 is provided at a position near the upper end of one vertical frame 33 of the shoji 3. As shown in FIG. 4, the detachment prevention member 4 has a locking piece 41 and an operating member 42 for rotating and moving the locking piece 41. The detachment prevention member 4 prevents the shoji 3 from detaching from the frame body 2 by locking the locking piece 41 to the frame body 2. FIGS. 3 and 4 show a state in which the locking piece 41 is disposed at the locking position with respect to the frame body 2.

[0026] The locking piece 41 is formed of a rectangular plate-like small piece that is long in one direction, and is disposed so as to be accommodatable in a locking groove 235 disposed on the outdoor side of the shoji 3 in the vertical frame 23 of the frame body 2. The locking piece 41 is disposed so as to be lockable to the vertical frame 23 of the frame body 2 on the outdoor side of the shoji 3. As shown in FIGS. 3 and 4, one end side in the length direction of the locking piece 41 is inserted into the locking groove 235 of the vertical frame 23, whereby the locking piece 41 is disposed at the locking position with respect to the vertical frame 23. At the locking position, the length direction of the locking piece 41 extends inward of the frame body 2 and is disposed substantially parallel to the outdoor wall portion 232 of the vertical frame 23.

[0027] The operating member 42 is formed of a columnar rod-like body and is provided so as to penetrate the vertical frame 33 of the shoji 3 in the indoor-outdoor direction. The operating member 42 is rotatable about the axis with respect to the vertical frame 33. As shown in FIG. 5, by rotating about the axis, the operating member 42 rotates and moves the locking piece 41 connected to the outdoor side between a locking position 41a where the locking piece 41 is inserted into the locking groove 235 of the vertical frame 23 and a locking release position 41b where the locking piece 41 is retracted from the locking groove 235.

[0028] The outdoor-side end of the operating member 42 is connected to the other end in the longitudinal direction of the locking piece 41 at a substantially right angle. The indoor-side end of the operating member 42 is rotatably supported by a support plate 43 attached to the metal core 331 of the vertical frame 33 and a sliding bearing 44 attached to the inner surface on the indoor side of the resin cover 332, respectively. The indoor-side end of the operating member 42 penetrates the resin cover 332 of the vertical frame 33 and is exposed on the indoor-side surface 33a of the vertical frame 33 so as to be rotatable from the indoor side. Specifically, as shown in FIG. 1, the indoor-side end of the operating member 42 is arranged at a position below the upper frame 21 in a state where the shoji 3 is attached to the frame body 2 and is exposed on the indoor-side surface 33a of the vertical frame 33. Therefore, the locking piece 41 can be easily rotated from the indoor side of the shoji 3 to the locking position 41a and the unlocking position 41b.

[0029] The sliding bearing 44 is made of rubber, resin or metal, contacts the outer peripheral surface of the operating member 42, and rotatably supports the operating member 42 with appropriate friction. The position around the axis of the operating member 42 when the locking piece 41 is arranged at the locking position 41a and the unlocking position 41b respectively is held by the friction of the sliding bearing 44. Therefore, the locking piece 41 does not rotate due to its own weight.

[0030] Next, a method of inserting the shoji 3 into the frame body 2 in a Kendon manner will be described. As shown in FIG. 6, the shoji 3 is inserted into the groove 214 of the upper frame 21 and the groove 224 of the lower frame 22 in a Kendon manner from the indoor side. That is, first, with the upper end side of the shoji 3 tilted to the outdoor side, the upper end of the shoji 3 is inserted deep into the groove 214 of the upper frame 21. After the shoji 3 is inserted, the lower end side of the shoji 3 is moved toward the outdoor side and aligned with the groove 224 of the lower frame 22. Then, the shoji 3 is lowered, and the lower end of the shoji 3 is inserted into the groove 224 of the lower frame 22. As a result, the upper end and the lower end of the shoji 3 are respectively accommodated in the grooves 214 and 224, and the shoji 3 is fitted and held between the upper frame 21 and the lower frame 22. At this time, as shown in FIG. 5, the locking piece 41 of the anti-disengagement member 4 is arranged at the unlocking position 41b with the tip side facing downward.

[0031] When the shoji 3 is held by the upper frame 21 and the lower frame 22, the vertical frames 23, 23 abut the sealing portions 236, 236 against the vertical frames 33, 33 of the shoji 3 from the outdoor side to regulate the position of the outdoor side of the shoji 3. The vertical frames 23, 23 only abut the sealing portions 236, 236 against the outdoor side surface of the shoji 3 and do not hold the shoji 3. The sealing portion 215 and the fin portion 216 of the upper frame 21 abut against the upper end portion of the shoji 3 from the outdoor side and the indoor side respectively, to ensure airtightness, prevent rattling of the upper end portion of the shoji 3, and prevent intrusion of dust etc. from the outside. The sealing portion 225 and the fin portion 226 of the lower frame 22 abut against the lower end portion of the shoji 3 from the outdoor side and the indoor side respectively, to ensure airtightness, prevent rattling of the lower end portion of the shoji 3, and prevent intrusion of dust etc. from the outside.

[0032] After the shoji 3 is attached to the frame body 2, the operating member 42 of the anti-disengagement member 4 is rotated 90° from the indoor side, and the tip side of the locking piece 41 is arranged at the locking position 41a with the tip side facing inward. Thereby, the tip side of the locking piece 41 is accommodated in the locking groove 235 of the vertical frame 23 and locked to the vertical frame 23 as shown in FIG. 4. In this state, the movement of the shoji 3 on the indoor side is restricted by the interference between the locking piece 41 and the locking wall portion 234 of the vertical frame 23. Therefore, not only when the shoji 3 moves upward, but also when it moves downward or when the position of the upper rail 31 of the shoji 3 drops, the engagement state between the shoji 3 and the frame body 2 can be maintained, and the shoji 3 can be prevented from coming off the frame body 2.

[0033] Since the locking piece 41 is provided so as to be lockable to the vertical frame 23, by providing at least one anti-disengagement member 4 on the frame body 30 of the shoji 3, the movement of the shoji 3 on the indoor side can be regulated regardless of whether the shoji 3 moves in the upper or lower direction. Therefore, the shoji 3 can be effectively prevented from coming off the frame body 2.

[0034] The indoor-side end of the operating member 42 may have a mark that can confirm whether the locking piece 41 is arranged at the locking position 41a or the unlocking position 41b. For example, FIGS. 7 and 8 show that a minus groove 421 for rotational operation by a minus driver is provided at the indoor-side end of the operating member 42. By aligning the length direction of the minus groove 421 with the length direction of the locking piece 41, it is possible to easily confirm whether the locking piece 41 is arranged at the locking position 41a (FIG. 7) or the unlocking position 41b (FIG. 8) just by visually observing the minus groove 421 of the operating member 42 from the indoor side of the shoji 3.

[0035] The mark provided at the indoor-side end of the operating member 42 is not limited to the minus groove 421. Although not shown, the mark may be a lever provided at the indoor-side end of the operating member 42, a grip portion extending in one direction, etc. By arranging the lever and the grip portion on the indoor-side surface 33a of the vertical frame 33, it is possible to easily confirm whether the locking piece 41 is arranged at the locking position 41a or the unlocking position 41b by visually observing the angle at which the lever and the grip portion are arranged.

[0036] The detachment prevention member 4 is arranged near the upper end of the vertical frame 33. However, the detachment prevention member 4 may be arranged, for example, near the center in the vertical direction of the vertical frame 33 or near the lower end of the vertical frame 33. The detachment prevention member 4 may be arranged near the upper end and the lower end of the vertical frame 33 respectively. The detachment prevention member 4 may be arranged on the left and right vertical frames 33, 33 respectively.

[0037] The detachment prevention member 4 only needs to be provided on the frame body 30 of the shoji 3 and is not limited to being provided on the vertical frame 33. The detachment prevention member 4 may be provided on at least one of the upper rail 31 and the lower rail 32.

[0038] The FIX window 1, which is a fitting shown in the above embodiment, has the following effects. That is, the FIX window 1 has a frame body 2 having an upper frame 21, a lower frame 22, and left and right vertical frames 23, 23, and having groove portions 214, 224 in the upper frame 21 and the lower frame 22 respectively, and a muntin 30 having an upper rail 31, a lower rail 32, and left and right vertical muntins 33, 33, with a facing material 34 on the inner side thereof, and a shoji 3 whose upper end portion and lower end portion are inserted into the groove portions 214, 224 respectively and is held by the upper frame 21 and the lower frame 22, and a detachment prevention member 4 provided on the muntin 30 to prevent the shoji 3 from coming off the frame body 2. The detachment prevention member 4 has a locking piece 41 disposed on the outdoor side of the shoji 3 and provided so as to be lockable to the frame body 2, and an operating member 42 for rotationally moving the locking piece 41 between a locking position 41a and a locking release position 41b. According to this, not only when the shoji 3 moves upward, but also when the shoji 3 moves downward or when the position of the upper rail 31 of the shoji 3 drops, the engagement state between the shoji 3 and the frame body 2 can be maintained, and the detachment of the shoji 3 from the frame body 2 can be prevented.

[0039] The outdoor-side end of the operating member 42 is connected to the locking piece 41, and the indoor-side end of the operating member 42 penetrates the shoji 3 and is disposed so as to be rotatable from the indoor side of the shoji 3. According to this, the locking piece 41 can be easily rotated between the locking position 41a and the locking release position 41b from the indoor side of the shoji 3.

[0040] The operating member 42 is rotatably supported by the muntin 30 by a sliding bearing 44 capable of holding the position around the axis. According to this, the position around the axis of the operating member 42 when the locking piece 41 is disposed at the locking position 41a and the locking release position 41b respectively is held by the friction of the sliding bearing 44. Therefore, the locking piece 41 does not rotate due to its own weight.

[0041] The indoor-side end of the operating member 42 has a minus groove 421 which is a mark that enables confirmation of whether the locking piece 41 is disposed at the locking position 41a or the unlocking position 41b. According to this, just by visually observing the minus groove 421 of the operating member 42 from the indoor side of the shoji 3, it is possible to easily confirm whether the locking piece 41 is disposed at the locking position 41a or the unlocking position 41b.

[0042] The locking piece 41 is provided so as to be lockable to the vertical frame 23. According to this, just by providing at least one anti-disengagement member 4 on the shoji 3, it is possible to regulate the movement of the indoor side of the shoji 3 regardless of whether the shoji 3 moves in the up or down direction. Therefore, it is possible to effectively prevent the shoji 3 from coming off the frame body 2.
