Although 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, they do not necessarily have to protrude at the same height.

The first hollow portion 221 and the second hollow portion 222 are arranged parallel to each other while being separated from each other in the indoor-outdoor direction. As a result, between the first hollow portion 221 , the second hollow portion 222 and the substrate portion 223 , a groove portion 224 is formed over the entire length of the lower frame 22 in the extending direction, similarly to the upper frame 21 . The groove 224 opens upward and accommodates the lower end of the shoji 3 . The substrate portion 223 constitutes the inner bottom surface of the groove portion 224 . The upper end portion of the first hollow portion 221 is integrally provided with a sealing portion 225 that protrudes toward the indoor side and elastically contacts the surface of the shoji 3 on the outdoor side. The upper end of the second hollow portion 222 is integrally provided with a fin portion 226 that protrudes toward the outside of the room and elastically contacts the surface of the shoji 3 on the inside of the room. The lower frame 22 is fixed to the lower inner surface of the frame 101 by a fixing screw SC2 passing through the base plate portion 223 .

The vertical frames 23 and 24 of the frame 2 are integrally extruded into a substantially L-shape from a resin material. The vertical frames 23 and 24 extend vertically across the space between the upper frame 21 and the lower frame 22 . The vertical frames 23 and 24 include substrate portions 231 and 241 extending with a predetermined width along the vertical direction of the frame 101, and outdoor wall portions extending from the outdoor end portions of the substrate portions 231 and 241 toward the inside of the frame 101 at substantially right angles. 232, 242, and contact pieces 233, 243 extending substantially perpendicularly from the inner ends of the exterior wall portions 232, 242 toward the interior of the room.

The contact piece portions 233 and 243 are narrower than the substrate portions 231 and 241 so as to contact the surface of the shoji 3 on the outdoor side. Sealing members 234 , 244 made of soft rubber or the like are provided at the ends of the contact pieces 233 , 243 , respectively, to elastically contact the surface of the shoji 3 on the outdoor side. The vertical frames 23 and 24 are fixed to the inner surfaces of the left and right side portions of the frame 101 by fixing screws SC3 and SC4 passing through the substrate portions 231 and 241, respectively.

The shoji 3 is constructed by placing a face material 35 such as glass inside a frame body 30 in which an upper rail 31, a lower rail 32, and left and right vertical frames 33, 34 are assembled into a rectangular frame. As shown in FIG. 2, the upper crosspiece 31 and the lower crosspiece 32 are composed of metal core members 311 and 321, resin cover members 312 and 322 covering the outer sides thereof, upper end surfaces and lower surfaces of the resin cover members 312 and 322. It is configured by a resin upper end cover member 313 and a resin lower end cover member 323 attached to the end faces. As shown in FIG. 3, the vertical frames 33 and 34 are respectively composed of metal core members 331 and 341 and resin cover members 332 and 342 covering the outer sides thereof.

As shown in FIG. 1, the shoji 3 has a vertical structure in which an upper crosspiece 31 and a lower crosspiece 32 are arranged between left and right vertical frames 33 and 34 . Specifically, the left and right vertical frames 33 and 34 extend over the entire length of the shoji 3 in the height direction. The upper rail 31 and the lower rail 32 are arranged between the left and right vertical rails 33 and 34, and connect the upper end portions and the lower end portions of the vertical rails 33 and 34, respectively. A substantially U-shaped handle 36 is attached to the central portion of the inner surface of the lower rail 32 .

The shoji 3 is inserted into the groove 214 of the upper frame 21 and the groove 224 of the lower frame 22 from the inside of the room in the following manner. First, the upper end of the shoji 3 is inserted deep into the groove 214 of the upper frame 21 . Next, the lower end of the shoji 3 is aligned with the groove 224 of the lower frame 22 . After that, the lower end of the shoji 3 is inserted into the groove 224 of the lower frame 22 by lowering the shoji 3 . As a result, the upper and lower ends of the shoji 3 are accommodated in the grooves 214 and 224, respectively, and the shoji 3 is fitted and held between the upper frame 21 and the lower frame 22. As shown in FIG. The left and right vertical frames 23 , 24 only bring the sealing members 233 a , 243 a at the tips of the contact pieces 233 , 243 into contact with the surface of the shoji 3 on the outdoor side, and do not hold the shoji 3 .

The groove 214 of the upper frame 21 and the groove 224 of the lower frame 22 have the same depth. However, as shown in FIG. 2, inside the groove 224 of the lower frame 22, a plurality of resin liners 227 for supporting 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 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 3 accommodated in the groove portion 224 of the lower frame 22 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 .

In this state, the upper end portion of the shoji 3 is engaged with the upper frame 21 while being accommodated in the groove 214 of the upper frame 21 . The lower end of the shoji 3 engages with the lower frame 22 while maintaining the state of being accommodated in the groove 224 of the lower frame 22 . 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 outside and the inside of the room, respectively. Thus, in the upper frame 21, it is possible to prevent the upper end of the shoji 3 from rattling, to prevent dust from entering from outside the room, and to ensure airtightness. The sealing portion 225 and the fin portion 226 of the lower frame 22 abut on the lower end portion of the shoji 3 from the outside and the inside of the room, respectively. As a result, in the lower frame 22, it is possible to prevent the lower end of the shoji 3 from rattling, to prevent dust from entering from outside the room, and to ensure airtightness.

The retaining member 4 is attached to the room-side surface 31 a of the upper beam 31 of the shoji 3 . As shown in FIG. 1, the retainer member 4 of this embodiment is arranged on each of the left and right ends of the surface 31a of the upper rail 31 on the room side. Only one of the two retaining members 4 provided on the surface 31a may be provided. Since the two retaining members 4 have the same structure, the left retaining member 4 shown in FIG. 1 will be described below with reference to FIGS. 4 to 6. FIG.

As shown in FIG. 4, the retaining member 4 includes a holding portion 41 that is a vertically long rectangular metal or resin case, and a locking tongue piece 42 that is housed inside the holding portion 41 and is made of a metal plate. Consists of The locking tongue piece 42 is formed in the shape of a long plate that is vertically longer than the holding portion 41 . A substantially lower half of the locking tongue piece 42 is inserted into the holding portion 41 . Approximately the upper half of the locking tongue piece 42 protrudes from the holding portion 41 into the groove portion 214 of the upper frame 21, as shown in FIGS. The corners of the upper ends of the locking tongue pieces 42 protruding from the holding portion 41 are chamfered in an R shape.

A long hole 411 elongated in the vertical direction is formed in the center of the wall portion 41a of the holding portion 41 on the indoor side. The long hole 411 integrally has a circular large diameter portion 411a at its lower end. A vertically elongated long hole 412 overlapping the long hole 411 is formed in the wall portion on the outdoor side of the holding portion 41 opposite to the wall portion 41 a on the indoor side. The long hole 412 does not have a large diameter portion at its lower end.

The locking tongue piece 42 inside the holding portion 41 is also formed with a vertically elongated long hole 421 so as to overlap the long holes 411 and 412 of the holding portion 41 . The elongated hole 421 of the locking tongue piece 42 has the same shape as the elongated hole 411 of the holding portion 41, and integrally has a circular large diameter portion 421a at the lower end.

The holding portion 41 integrally has a protruding portion 413 that protrudes upward. The protruding portion 413 is arranged on the upper surface of the holding portion 41 closer to the surface 31 a of the upper rail 31 on the interior side than the locking tongue piece 42 . The projecting portion 413 has the same width as the lateral width of the holding portion 41 and has a projecting height smaller than the projecting height of the locking tongue piece 42 .

The retaining member 4 is attached to the upper crosspiece 31 from the inside of the room with one fixing screw 43 . Specifically, the retaining member 4 is temporarily fixed by a fixing screw 43 to the inner surface 31 a of the upper beam 31 of the shoji 3 before being attached to the frame 2 . At this time, the shaft portion 431 of the fixing screw 43 is arranged on the upper end side of the long holes 411 and 412 of the holding portion 41 and the long hole 421 of the locking tongue piece 42 . A head portion 432 of the fixing screw 43 is arranged on the surface of the wall portion 41a of the holding portion 41 on the interior side. Therefore, the retaining member 4 is temporarily fixed at a position lower than the final mounting position.

After the shoji 3 is fitted into the frame 2 by the Kendon method, the retaining member 4 is moved along the long holes 411, 412, 421 until the heads 432 of the fixing screws 43 are positioned at the large diameter portions 411a, 421a. slide upwards. As a result, the locking tongue piece 42 is inserted into the groove 214 of the upper frame 21 through the gap between the first hollow portion 212 of the upper frame 21 and the upper beam 31 of the shoji 3, as shown in FIG. The upper end portion 42a of the locking tongue piece 42 in the groove portion 214 is arranged close to the base portion 213 of the upper frame 21 with a very small gap left. The distance d1 between the upper end portion 42a of the locking tongue piece 42 and the base plate portion 213 is greater than the distance d2 (see FIG. 2) at which the lower end portion of the shoji 3 is inserted into the groove portion 224 of the lower frame 22 and engaged with the lower frame 22. is also small.

After the head 432 of the fixing screw 43 is positioned at the large diameter portions 411a and 412a, the fixing screw 43 is tightened. As a result, the wall portion of the holding portion 41 on the outdoor side is clamped between the head portion 432 of the fixing screw 43 and the upper rail 31 of the shoji 3 , and the retaining member 4 is fixed to the upper rail 31 . A shaft portion 431 of the fixing screw 43 passes through the resin cover material 312 of the upper rail 31 and is screwed into the metal core material 311 . In a state where the retaining member 4 is fixed to the upper rail 31 by the fixing screw 43, the locking tongue piece 42 is held within the holding portion 41 so as not to move.

The retaining members 4 are attached in contact with stepped portions formed on the upper rail 31 at the upper corners of the left and right ends of the upper rail 31 . Specifically, the thickness of the upper rail 31 in the indoor-outdoor direction is slightly thicker than the thickness of the left and right vertical frames 33 and 34 in the indoor-outdoor direction. Therefore, as shown in FIG. 6, a first stepped portion 30a extending in the vertical direction is formed on the left and right ends of the surface 31a of the upper rail 31 on the indoor side due to the dimensional difference between the upper rail 31 and the vertical rails 33 and 34. is formed. The first step portion 30a is formed by the inner end surfaces of the vertical frames 33 and 34. As shown in FIG. The holding portion 41 is attached such that side end surfaces 41b that are arranged on the left and right sides of the holding portion 41 and extend linearly in the vertical direction are in contact with each other along the first step portion 30a. As a result, the first stepped portion 30a functions as a rotation stopper that prevents movement of the retaining member 4 in the rotational direction around the fixing screw 43. As shown in FIG. When sliding the retaining member 4 in the vertical direction, the retaining member 4 is guided linearly along the first stepped portion 30a, so that the retaining member 4 can be easily moved to a predetermined position without rotating. can be positioned.

As shown in FIG. 4 , tapered portions 411 b are formed on both sides of the long hole 411 of the holding portion 41 to guide the head portion 432 of the fixing screw 43 to the large diameter portion 411 a of the long hole 411 . Therefore, when the fixing screw 43 is tightened after sliding the retaining member 4 upward, even if the head 432 of the fixing screw 43 and the large-diameter portion 411a are slightly misaligned, the head 432 can be tapered. It can be guided into the large diameter portion 411a along the portion 411b.

The upper end cover material 313 attached to the upper end surface of the upper rail 31 of the shoji 3 has a dimension in the indoor-outdoor direction that is slightly larger than the dimension in the indoor-outdoor direction of the resin-made cover material 312, and the upper end surface of the resin-made cover material 312. mounted so as to fit outwardly against the Therefore, as shown in FIG. 5, the frame body 30 of the shoji 3 has an end portion 313a of the upper end cover member 313 that protrudes further into the room than the resin cover member 312 and the surface 31a of the upper rail 31 that faces the room. A second stepped portion 30b extending in the lateral direction is formed therebetween. When the retaining member 4 slides upward, the projecting portion 413 of the holding portion 41 abuts against the second stepped portion 30b. As a result, the second stepped portion 30b functions as another rotation stopper that prevents the rotation of the retainer member 4 about the fixing screw 43 in the rotational direction. The projecting portion 413 of the holding portion 41 abuts against the second stepped portion 30b, so that the upper end position of the retaining member 4 in the movement direction is easily positioned when the retaining member 4 is slid upward.

Next, the operation of the FIX window 1 having the retaining member 4 attached to the upper part of the shoji 3 will be described.

The locking tongue piece 42 of the retaining member 4 is inserted into the groove 214 of the upper frame 21 from the upper crosspiece 31 of the shoji 3 and arranged close to the base plate portion 213 of the upper frame 21 . In this state, for example, even if the frame 30 of the shoji 3 shrinks due to thermal deformation or the lower frame 21 bends due to poor construction of the frame 2, even if the shoji 3 moves downward, the retaining member 4 retains the state of being inserted into the groove 214 of the upper frame 21 . Therefore, the engagement between the shoji 3 and the upper frame 21 is not released, and the detachment of the shoji 3 from the frame 2 is prevented. Even if the shoji 3 moves upward due to vertical shaking such as an earthquake, the upper end portion 42a of the locking tongue piece 42 of the detent member 4 contacts the base portion 213 of the upper frame 21, and the upward movement of the shoji 3 is prevented. Regulated. At this time, since d1<d2, the shoji 3 does not come off the lower frame 22.例文帳に追加

The detent member 4 is moved by the contact between the side end surface 41b of the holding portion 41, the first stepped portion 30a of the frame 30, and the projecting portion 413 of the holding portion 41 and the second stepped portion 30b of the frame 30. Rotation to 3 is blocked. Therefore, for example, even if the fixing screw 43 is loosened due to long-term use, the retaining member 4 will not shift in the rotational direction with respect to the shoji 3 and rattle.

Since the first stepped portion 30a and the second stepped portion 30b with which the retaining member 4 contacts extend in two directions substantially perpendicular to each other, the movement of the retaining member 4 in the rotational direction is more reliably prevented. can be done. Moreover, the stopper member 4 contacts the first stepped portion 30a and the second stepped portion 30b, so that the stopper member 4 can be easily positioned at a predetermined position with respect to the upper frame 31 of the shoji 3. be able to. Only one of the first stepped portion 30a and the second stepped portion 30b may be the rotation preventing portion that contacts the detachment preventing member 4 .

As described above, the FIX window 1 of this embodiment has the following effects. That is, the FIX window 1 of this embodiment includes a frame body 2 having an upper frame 21, a lower frame 22, left and right vertical frames 23 and 24, and having grooves 214 and 224 in the upper frame 21 and the lower frame 22, and an upper rail. 31, a lower crosspiece 32, and left and right vertical bars 33, 34. A frame 35 is provided inside the frame 30, and the upper and lower ends are inserted into the grooves 214, 224 to form the upper frame 21 and the lower frame. A shoji 3 held by 22, a detachment prevention member 4 provided on the upper rail 31 of the shoji 3 so as to protrude into the groove 214 of the upper frame 21 and prevent the shoji 3 from coming off the upper frame 21; a rotation stopping part which is arranged on the upper rail 31 of the shoji 3 and prevents the rotation of the retaining member 4 with respect to the shoji 3 by coming into contact with the retaining member 4. - 特許庁According to this, even if the frame 30 of the shoji 3 shrinks due to thermal deformation, or the lower frame 21 bends due to poor construction of the frame 2, etc., and the shoji 3 moves downward, the detent member 4 By this, the engagement state between the shoji 3 and the upper frame 21 can be maintained. Therefore, the shoji 3 is prevented from coming off the frame 2. - 特許庁Moreover, the stopper member 4 is prevented from rotating with respect to the shoji 3 by contact with the rotation stopper portion arranged on the upper frame 31 of the shoji 3, so that the stopper member 4 is positioned in the rotation direction with respect to the shoji 3 There is no rattling due to slippage.

The rotation stoppers may be first stepped portions 30a arranged at the left and right ends of the upper beam 31 and extending in the vertical direction. According to this, in addition to being able to prevent the movement of the retaining member 4 in the rotational direction, the retaining member 4 can be linearly guided along the first stepped portion 30a when it is slid in the vertical direction. . Therefore, the retaining member 4 can be easily positioned at a predetermined position without rotating.

The rotation stopping portion may be a second stepped portion 30b arranged at the upper end portion of the upper rail 31 and extending in the horizontal direction. According to this, in addition to preventing the movement of the retaining member 4 in the rotational direction, the projecting portion 413 of the holding portion 41 abuts the second stepped portion 30b, thereby causing the retaining member 4 to slide upward. Furthermore, the position of the upper end of the stopper member 4 in the moving direction can be easily positioned.

The upper frame 21 and the lower frame 22 and the upper rail 31 and the lower rail 32 each contain a resin material. According to this, the FIX window 1 has an effect of preventing the shoji 3 from being detached from the frame 2, and is also excellent in heat insulation and condensation prevention.

Although not shown, the rotation stopper that comes in contact with the stopper member 4 to prevent its movement in the direction of rotation may be formed by a projection projecting from the surface 31a of the upper rail 31 toward the inside of the room. . Although not shown, the rotation stopper may be configured by a concave portion capable of accommodating a convex portion provided on the detent member 4 .
