Description

[Technical Field]

[0001] The present invention relates to a resin frame material and a building material. [Background technology]

[0002] Resin sashes are known in the art (see, for example, Patent Document 1). The resin sash described in Patent Document 1 includes a frame material and a cover material, each made of recycled resin. The frame material includes a holding surface that holds the edge of the window glass, a first fitting portion provided on the interior side adjacent to the holding surface, and a first clamping portion extending approximately perpendicularly from the holding surface. A cover material is fitted into the first fitting portion. The first clamping portion and holding surface of the frame material and the cover material form a recess that receives the window glass. A pair of airtight materials are provided within the recess. The airtight material on the exterior side is sandwiched between the cover material and the window glass. The airtight material on the interior side is sandwiched between the first clamping portion of the frame material and the window glass. A film is provided on the surface of the resin sash as needed.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-216558 Summary of the Invention [Problem to be solved by the invention]

[0004] In plastic sashes made from recycled resin, such as those described in Patent Document 1, the colors of the frame and cover materials on which the film is applied may vary depending on the production lot because the recycled resin contains various materials. For example, when applying a film to the first clamping portion of the frame material, it is preferable to cut the film at a position closer to the interior than the edge of the glass to avoid damaging the airtight material. However, cutting the film at a position closer to the interior than the edge of the glass may expose the recycled resin, potentially reducing the design quality of the plastic sash. In order to prevent such a decrease in design, it is possible to cut the film along the edge of the first clamping portion on the glass side, or to position the film so that the edge of the glass side and the edge of the film are aligned, but such work is time-consuming.

[0005] The object of the present invention is to provide a resin frame material and fittings that can be easily worked on and that can suppress the deterioration of design while suppressing the generation of resin waste. [Means for solving the problem]

[0006] The resin frame material of the present invention comprises a frame material main body having a recycled resin portion made of recycled resin and an unused resin portion made of unused resin, and an airtight material provided on the frame material main body, wherein the frame material main body comprises an airtight material placement surface on which the airtight material is provided, and a sheet material adhesive surface to which a sheet material is adhered, the sheet material adhesive surface being provided so as to extend from an edge of the airtight material placement surface in a direction away from the airtight material, and the airtight material side region of the sheet material adhesive surface including the edge on the airtight material placement surface side is composed of the unused resin portion.

[0007] The building fixture of the present invention comprises a frame-shaped frame body, a surface material, and a shoji screen having the above-mentioned resin frame material fixed to the surface material, which opens and closes the opening of the frame body, and is characterized in that the airtight material is arranged on the airtight material placement surface so that the airtight material abuts the visible surface of the surface material.

[0008] The building fixture of the present invention is characterized in that it comprises a frame body formed into a frame shape using the above-mentioned resin frame material, and a shoji screen that opens and closes the opening of the frame body, and the airtight material is arranged on the airtight material placement surface so that the airtight material abuts against the visible surface of the shoji screen.

An airtight material engaging portion 242F is provided at the upper end portion of the second inner peripheral visible surface portion 242B, with which the shoji airtight material 25 engages. The shoji airtight material 25 is provided over the entire length of the frame body 24 so as to abut against the resin bottom frame 42 when the shoji 3 is closed. A downwardly recessed portion 242G is provided on the exterior side of the third inner peripheral visible surface portion 242C. A claw portion 242H made of unused hard PVC is provided in the recessed portion 242G. The outer peripheral sight surface portion 244 is provided so as to connect the lower ends of the indoor sight surface portion 241 and the outdoor sight surface portion 243 to each other. The outdoor protrusion 245 is provided so as to protrude in a plate-like shape toward the indoor side from the connection portion between the indoor side visible surface 241 and the outer peripheral side visible surface 244.

[0016] Shoji airtight material 25 is made of soft TPE (thermoplastic elastomer). The center side unused resin portion 26 is made of unused hard PVC (virgin resin). The center side unused resin portion 26 includes a first center side unused resin layer 261 and a second center side unused resin layer 262.

[0017] The first center-side unused resin layer 261 is provided in a layered form above the airtight material engaging portion 242F on the surface of the second inner peripheral side prospective surface portion 242B. The surface of the first center-side unused resin layer 261 constitutes the airtight material placement surface 281. The second center-side unused resin layer 262 is provided in a layered form on the surface of the first inner periphery-side exposed surface portion 242A on the side of the second inner periphery-side exposed surface portion 242B so as to be continuous with the first center-side unused resin layer 261. The surface of the second center-side unused resin layer 262, together with an exposed region on the surface of the first center-side exposed surface portion 242A where the second center-side unused resin layer 262 is not provided, is formed so as to constitute a planar sheet material adhesive surface 282. The surface of the second central unused resin layer 262 constitutes an airtight material side region 283 including the edge of the sheet material adhesive surface 282 on the airtight material placement surface 281 side.

[0018] The outer unused resin portion 27 is made of unused hard PVC (unused resin) and is provided in a layer below the airtight material engagement portion 242F on the surface of the second inner peripheral side visible surface portion 242B and on the surface of the third inner peripheral side visible surface portion 242C.

[0019] As shown in FIG. 4, the resin lower frame 42 includes a frame body 44 as a frame material body, an airtight material 45 for the surface material, and a ledge 46. The frame body 44 includes a base portion 47 as a recycled resin portion, an inner peripheral side unused resin portion 48, and an outer peripheral side unused resin portion 49. The base 47 is formed to extend in the X-axis direction and is formed into a hollow frame shape from recycled resin. The recycled resin is mainly made of PVC. The base 47 includes an indoor facing surface 471, an inner peripheral facing surface 472, an outdoor facing surface 473, an outer peripheral facing surface 474, a first partition 475, a second partition 476, a third partition 477, and a fourth partition 478.

[0020] The inner peripheral projection surface portion 472 includes a first inner peripheral projection surface portion 472A extending from the upper end of the indoor side sight surface portion 471 to the outdoor side, a second inner peripheral projection surface portion 472B extending downward from the outdoor side end of the first inner peripheral projection surface portion 472A, and a third inner peripheral projection surface portion 472C connecting the lower end of the second inner peripheral projection surface portion 472B to the upper end of the outdoor side sight surface portion 473. On the outdoor side of the third inner peripheral projection surface portion 472C, a setting block engagement portion 472D with which the setting block 33 engages and a pressing edge engagement portion 472E with which the pressing edge 46 engages are provided.

[0021] The outer periphery-side visible surface portion 474 includes a first outer periphery-side visible surface portion 474A extending from the lower end of the indoor-side visible surface portion 471 to the outdoor side, a second outer periphery-side visible surface portion 474B extending downward from the outdoor-side end of the first outer periphery-side visible surface portion 474A, and a third outer periphery-side visible surface portion 474C connecting the lower end of the second outer periphery-side visible surface portion 474B to the lower end of the outdoor-side visible surface portion 473. A recess 474D recessed upward is provided on the outdoor side of the indoor-side end of the first outer periphery-side visible surface portion 474A. A frame airtight material 50 made of soft PVC is integrally provided on the lower end of the second outer periphery-side visible surface portion 474B. The frame airtight material 50 is provided over the entire length of the base 47 so as to abut against the fourth inner peripheral visible surface portion 242D of the lower frame 22 when the shoji screen 3 is closed.

[0022] The first partition 475 extends downward from a portion of the third inner peripheral projection surface 472C facing the room and connects to the first outer peripheral projection surface 474A. The second partition 476 extends obliquely upward from the outdoor end of the first outer peripheral projection surface 474A and connects to the third inner peripheral projection surface 472C. The third partition 477 is provided at a position closer to the room than the second partition 476, connecting the first outer peripheral projection surface 474A and the third inner peripheral projection surface 472C and extending in the vertical direction. The fourth partition 478 extends from a portion of the upper end of the second outer peripheral projection surface 474B facing the room outside and connects to the outdoor projection surface 473.

[0023] The inner circumference side unused resin portion 48 is provided over the entire length of the base portion 47 and is made of unused hard PVC (virgin resin). The inner circumference side unused resin portion 48 includes a first inner circumference side unused resin layer 481 and a second inner circumference side unused resin layer 482.

[0024] The first inner circumference side unused resin layer 481 is provided in a layered form on the surface of the second inner circumference side expected surface portion 472B on the side of the first inner circumference side expected surface portion 472A. Of the surface of the first inner circumference side unused resin layer 481, an upper end region forms the airtight material placement surface 51, and a central region forms the surface material bonding surface 52. An airtight material 45 for the face material, made of unused soft PVC, is integrally provided on the airtight material placement surface 51. The airtight material 45 for the face material is provided so as to abut the visible surface of the face material 30 on the indoor side over the entire length of the base 47. The face material adhesive surface 52 is bonded to the end of the facing surface on the indoor side of the face material 30 via adhesive 92 over the entire length of the base 47. In this way, the face material adhesive surface 52, which is made of the first inner peripheral unused resin layer 481, whose composition does not vary depending on the production lot, and the face material 30 are fixed together with adhesive 92, which reduces the generation of resin waste and also reduces the variation in the adhesion between the resin bottom frame 42 and the face material 30. Furthermore, because the face material adhesive surface 52 is made of the first inner peripheral unused resin layer 481 provided on the second inner peripheral facing surface portion 472B made of recycled resin, it is possible to reduce the amount of unused resin used and increase the amount of recycled resin used, thereby further reducing the generation of resin waste.

[0025] The second inner circumference side unused resin layer 482 is provided in a layered form on the surface of the first inner circumference side exposed surface portion 472A on the side of the second inner circumference side exposed surface portion 472B so as to be continuous with the first inner circumference side unused resin layer 481. The surface of the second inner circumference side unused resin layer 482, together with an exposed region on the surface of the first inner circumference side exposed surface portion 472A where the second inner circumference side unused resin layer 482 is not provided, is formed so as to constitute the planar sheet material adhesive surface 53. The surface of the second inner peripheral side unused resin layer 482 constitutes an airtight material side region 54 including the edge of the sheet material bonding surface 53 on the airtight material placement surface 51 side.

[0026] The outer peripheral side unused resin portion 49 is made of unused hard PVC and includes a first outer peripheral side unused resin layer 491 and a second outer peripheral side unused resin layer 492. First outer periphery side unused resin layer 491 is provided in a layer form on the surface of first outer periphery side visible surface portion 474A excluding the indoor side surface of the indoor side wall portion that constitutes recess 474D. The second outer peripheral side unused resin layer 492 is provided over the entire area on the surface of the second outer peripheral side visible surface portion 474B where the frame body airtight material 50 is not provided, so as to be continuous with the first outer peripheral side unused resin layer 491. The surface of the outer peripheral unused resin portion 49 constitutes an open-time exposed area 55 that is exposed when the shoji screen 3 is open but not when closed. The surface of the third outer peripheral visible surface portion 474C, which is not provided with the outer peripheral unused resin portion 49, and the open-time exposed area 55 constitute the outer peripheral visible surface. By forming the open-time exposed area 55 from the outer peripheral unused resin portion 49 provided on the outer peripheral visible surface portion 474 made of recycled resin in this way, the generation of resin waste can be further reduced and a decrease in the design of the vertical sliding window 1 can be prevented.

[0027] The base 47, inner unused resin portion 48, outer unused resin portion 49, face material airtight material 45, and frame airtight material 50 having the above-described configuration are integrally formed by extrusion molding. Because the airtight material placement surface 51, face material bonding surface 52, and airtight material side region 54 are made up of a single inner unused resin portion 48, they can be more easily provided on the resin bottom frame 42 than if they were made up of separate pieces of unused PVC. In particular, the use of extrusion molding makes it easier to manufacture the resin bottom frame 42. Furthermore, since the virgin resin constituting the inner peripheral virgin resin portion 48 and the outer peripheral virgin resin portion 49 is made of the same PVC as the main material of the base portion 47, extrusion properties can be improved. Furthermore, since the frame body 44 and the surface material airtight material 45 are integrally formed, the task of placing the surface material airtight material 45 on the frame body 44 is not required, making it easier to manufacture the resin lower frame 42.

[0028] The flange 46 is formed to the same length as the resin bottom frame 42 and is made of unused hard PVC. The base end of the flange 46 is engaged with the flange engagement portion 472E of the resin bottom frame 42. The tip of the flange 46 is provided with a bead material 461 that abuts against the exterior facing surface of the face material 30.

[0029] A sheet material 6 is adhered to the surface of the resin sill 42 that is exposed when the shoji screen 3 is closed. The sheet material 6 is, for example, a resin laminate film, and is provided with a pattern or color to enhance the design of the vertical sliding window 1. The sheet material 6 comprises a first indoor-side sheet material 61 adhered to the indoor side of the resin sill 42, a first outdoor-side sheet material 62 adhered to the outdoor side of the resin sill 42, an edge-side sheet material 63 adhered to the edge 46, a second indoor-side sheet material 64 adhered to the indoor side of the sill 22, and a second outdoor-side sheet material 65 adhered to the outdoor side of the sill 22. In this way, the first indoor sheet material 61, the first outdoor sheet material 62 and the edge-side sheet material 63 are adhered to the surface including the sheet material adhesive surface 53 which is exposed to the indoor and outdoor sides when the shoji screen 3 is closed, and the second indoor sheet material 64 and the second outdoor sheet material 65 are adhered to the surface including the sheet material adhesive surface 282 which is exposed to the indoor and outdoor sides of the frame body 2, thereby further enhancing the design of the vertical sliding window 1.

[0030] The first indoor-side sheet material 61 has a surface that is the same shape as the combined shape of the sheet material adhesive surface 53, the surface of the indoor-side visible surface portion 471, the indoor-side surface and underside of the indoor-side wall portion that forms the recess 474D on the surface of the first outer peripheral visible surface portion 474A, and the area extending from that area to the outside, and is continuously bonded over the entirety of these surfaces. The second indoor-side sheet material 64 has a surface that is the same shape as the combined shape of the sheet material adhesive surface 282, the surface of the indoor-side visible surface portion 241, and part of the upper surface, indoor-side surface, and underside of the outside-side protruding portion 245, and is continuously bonded over the entirety of these surfaces. In this way, when the first and second indoor sheet materials 61, 64 are adhered to the sheet material adhesive surface 53, 282, even if the first and second indoor sheet materials 61, 64 are cut at a position on the indoor side (toward the extension direction of the sheet material adhesive surface 53, 282) of the boundary with the airtight material placement surface 51, 281 on the sheet material adhesive surface 53, 282 in order to avoid damaging the airtight material for face materials 45 or the airtight material for shoji screens 25, the first inner peripheral visible surface portion 472A, 242A made of recycled resin, which contains various materials and is therefore likely to vary in color depending on the production lot, will not be exposed, and instead the airtight material side region 54, 283, which is composed of the second inner peripheral unused resin layer 482 and the second central unused resin layer 262 and does not vary in color depending on the production lot, will be exposed. This makes it easier to prevent a decrease in the design of the vertical sliding window 1 than to cut the first and second indoor-side sheet materials 61, 64 at the boundary between the sheet material adhesive surfaces 53, 282 and the airtight material placement surfaces 51, 281, or to adhere the first and second indoor-side sheet materials 61, 64 so that the boundary and the edge of the first and second indoor-side sheet materials 61, 64 are aligned. Also, because the airtight material side region 54, 283 is formed from the second inner circumference unused resin layer 482 and the second central side unused resin layer 262 provided on the first inner circumference visible surface portion 472A, 242A made of recycled resin, it is possible to reduce the amount of unused resin used and increase the amount of recycled resin used, thereby further reducing the generation of resin waste. The surface of the first outdoor sheet material 62 has the same shape as the upper surface of the outdoor wall portion that constitutes the edge engagement portion 472E, as well as the combined surfaces of the outdoor visible surface portion 473 and the third outer peripheral visible surface portion 474C, and is continuously adhered across the entire surface of these surfaces. The surface of the edge-side sheet material 63 has the same shape as the surface of the edge 46 exposed to the outside of the room and the surface facing the upper surface of the wall portion on the outside of the room that constitutes the edge engagement portion 472E, and is adhered to the entire exposed surface. The surface of the second outdoor sheet material 65 has the same shape as the upper surface of the outdoor wall portion that forms the recess 242G, as well as the combined surfaces of the outdoor regions of the fourth inner peripheral visible surface portion 242D, the fifth inner peripheral visible surface portion 242E, the outdoor visible surface portion 243 and the outer peripheral visible surface portion 244, and is continuously adhered across the entire surface.

[0031] [Variations] The second inner peripheral side unused resin layer 482 including the airtight material side region 54 is provided in a layered form on the first inner peripheral side prospective surface portion 472A made of recycled resin, but the portion of the first inner peripheral side prospective surface portion 472A on the second inner peripheral side prospective surface portion 472B side including the airtight material side region 54 may be made only of unused PVC, and the remaining portion may be made of recycled resin. The airtight material 45 for the surface material and the base 47 are formed integrally, but an airtight material engagement portion may be provided on the second inner peripheral side projection surface portion 472B, and the airtight material 45 for the surface material may be engaged with the airtight material engagement portion. The inner circumference unused resin portion 48 may be formed only from the second inner circumference unused resin layer 482, and the frame body 44 may not be provided with an airtight material placement surface 51 and a surface material bonding surface 52 made of unused PVC, or the inner circumference unused resin portion 48 may be formed only from the portion including the airtight material placement surface 51 in the first inner circumference unused resin layer 481, and the frame body 44 may not be provided with a surface material bonding surface 52 made of unused PVC. The first inner peripheral side unused resin layer 481 including the surface material adhesive surface 52 is provided in a layered form on the second inner peripheral side prospective surface portion 472B made of recycled resin, but the portion of the second inner peripheral side prospective surface portion 472B on the first inner peripheral side prospective surface portion 472A side including the surface material adhesive surface 52 may be made only of unused PVC, and the remaining portion may be made of recycled resin. The airtight material placement surface 51, the surface material bonding surface 52 and the airtight material side region 54 are made up of a single inner peripheral unused resin portion 48, but these may also be made up of separate unused PVC, or only the airtight material placement surface 51 and the surface material bonding surface 52 may be made up of a single unused PVC, or only the airtight material placement surface 51 and the airtight material side region 54 may be made up of a single unused PVC. Although the inner peripheral unused resin portion 48 is made of unused PVC, it may be made of unused resin other than PVC, such as acrylic. The frame body 44 does not need to have an outer peripheral unused resin portion 49, and the open-time exposed area 55 made of unused PVC does not need to be provided on the frame body 44, or the first and second outer peripheral visible surface portions 474A, 474B including the open-time exposed area 55 on the outer peripheral visible surface portion 474 may be made of unused PVC only. The thickness of at least one of the inner peripheral unused resin portion 48 and the outer peripheral unused resin portion 49 may be approximately the same as that of the base portion 47 or may be thicker than that of the base portion 47 . When an airtight material side region 54 is provided on the sheet material adhesive surface 53, it is not necessary to provide an airtight material side region 283 on the sheet material adhesive surface 282, and when an airtight material side region 283 is provided on the sheet material adhesive surface 282, it is not necessary to provide an airtight material side region 54 on the sheet material adhesive surface 53. For example, in a configuration in which a resin frame material is bonded to the outer peripheral surface (visible surface) of a surface material made of glass, resin, metal, etc., the surface material bonding surface of the resin frame material may be formed of an unused resin portion. Although the description has been given of a vertical sliding window 1 as a fixture, other types of windows may also be used, such as horizontal sliding windows, casement windows such as projection windows and hinged windows, or sliding windows such as double sliding windows, single sliding windows and casement windows.
