[0003] [Patent Document 1] JP 2021-101084 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the resin frame material described in Patent Document 1, for example, no surface material is provided on the outer peripheral groove portion of the resin frame material such as the door end frame, i.e., the portion that constitutes the outer peripheral visible surface that faces the resin frame material. Here, the portion made of recycled resin material often unintentionally has a different color from the portion made of virgin resin material, and is therefore a portion that should not be exposed to the outside, but in the resin frame material described in Patent Document 1, the outer peripheral visible surface portion made of recycled resin material is exposed to the outside when the resin sash is opened, etc., and there is a risk that the external design will be impaired.

[0005] An object of the present invention is to provide a resin shoji screen and a resin frame material which can improve the appearance design while reducing costs by using recycled resin materials. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Figures 1 and 2, a vertical sliding window 1 as a fixture with a resin screen in this embodiment comprises a resin frame body 2 as a frame body to be installed in an opening in a building structure, and a resin screen 3 arranged within the resin frame body 2 so as to be able to be opened and closed in the out-of-plane direction; by operating a handle 91 provided on the resin screen 3, a latch mechanism 90 formed in the resin frame body 2 and the resin screen 3 is activated to enable the window to be opened or closed. In the following description, the left-right direction of the vertical sliding window 1 is the X-axis direction, the up-down direction of the vertical sliding window 1 is the Y-axis direction, and the projection direction of the vertical sliding window 1 is the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other. The X and Y axis directions are along the in-plane direction of the vertical sliding window 1, and the Z axis direction is along the out-of-plane direction of the vertical sliding window 1.

[0010] The resin frame 2 is formed by framing an upper frame 21, a lower frame 22, and left and right vertical frames 23, which are frame materials. The upper frame 21, the lower frame 22, and the left and right vertical frames 23 are each formed into a hollow frame shape using a common extruded shape material made of synthetic resin, and a surface layer is provided on the exterior and interior parts of each, and in this embodiment, an acrylic laminate 8 is provided as the surface layer on the exterior part, and a PVC (polyvinyl chloride) laminate 8B is provided as the surface layer on the interior part. The main body parts of the upper frame 21, the lower frame 22, and the left and right vertical frames 23 are made of unused resin material, but the parts not exposed to the outside may be made of recycled resin material.

[0011] As shown in Figure 3, the resin shoji screen 3 comprises a rectangular plate-shaped panel 30 and a frame 35 composed of a resin frame material 40 arranged along the edge 301 of the panel 30, and the panel 30 is housed in the frame 35. 1 and 2, the face material 30 in this embodiment is configured by interposing spacers 32 between the edges of three panel plates 31 such as glass panels, thereby forming a hollow layer between the three panel plates 31. In this manner, the face material 30 in this embodiment is configured as laminated glass. The frame 35 is constructed by assembling resin frame materials 40 on all four sides. Each resin frame material 40 is constructed as an upper frame 41, a lower frame 42, and left and right vertical frames 43. In this embodiment, the vertical frame 43 shown on the right side in Fig. 2 is the door end vertical frame, and the vertical frame 43 shown on the left side is the hanging end vertical frame. The upper frame 41, the lower frame 42, and the left and right vertical frames 43 are each formed into a hollow frame shape using a common extruded shape made of synthetic resin, and an acrylic laminate 8 is provided as a surface layer on the outdoor side.

[0012] Below, the lower frame 42 will be described as an explanation of the resin frame material 40. The components of the upper frame 41 and the left and right vertical frames 43 will be appropriately designated with the same reference numerals as those of the lower frame 42, and explanations thereof will be omitted. As shown in FIG. 3, the lower frame 42 integrally includes an exterior facing surface 46, an interior facing surface 47, an inner peripheral facing surface 48 disposed between the exterior facing surface 46 and the interior facing surface 47 in the Z-axis direction, and an outer peripheral facing surface 49 disposed between the exterior facing surface 46 and the interior facing surface 47 and at a position on the outer peripheral side of the inner peripheral facing surface 48. The lower frame 42 is provided with a ridge 51 that engages with a ridge engagement portion 50 formed in a portion where the exterior facing surface 46 and the inner peripheral facing surface 48 are continuous. The ridge 51 includes a ridge base material 52 made of unused resin material and an acrylic laminate 8 as a surface layer that covers the surface of the ridge base material 52 on the exterior side. An engaged portion 54 that engages with the ridge engagement portion 50 is formed at the base end of the ridge base material 52, and a bead material 55 that abuts against the exterior surface 30A of the surface material 30 is provided at the tip of the ridge base material 52.

[0013] In this embodiment, the exterior facing surface portion 46 and the interior facing surface portion 47 are formed from unused resin material and are aligned along the in-plane direction of the vertical sliding window 1. The exterior facing surface portion 46 is provided with an acrylic laminate 8 as a surface layer that covers, from the outside of the room, the outer surface (surface) of a main body layer 461 formed from unused resin material. The interior facing surface portion 47 is provided with a weatherstripping material 61 that abuts against the sill 22.

[0014] The inner peripheral side visible surface portion 48 is continuous at its exterior end with the exterior visible surface portion 46, and is continuous at its indoor end with the indoor visible surface portion 47. The inner peripheral side visible surface portion 48 has a stepped receiving portion 481 that receives the indoor surface 30B of the facing material 30, and the receiving portion 481 extends inward from a portion of the inner peripheral side visible surface portion 48 that constitutes a facing material retaining groove 401 (described later) and faces the indoor surface 30B of the facing material 30 in the Z-axis direction. The portion of the outer peripheral projection surface 49 facing the edge 301 of the panel 30 and the portion of the receiving portion 481 within a range that does not protrude inward from the spacer 32 of the panel 30 are made of recycled resin material, and the remaining portions are made of unused resin material. The portion of the inner peripheral projection surface 48 made of unused resin material is the portion of the receiving portion 481 that is bonded to the indoor surface 30B of the panel 30 and the portion that is more inward than that portion. The partition piece 483, which will be described later, is also made of recycled resin material. The portion made of recycled resin material in this way is the portion of the resin screen 3 that is not exposed to the outside, so there is no risk of the recycled resin material being exposed to the outside and damaging the appearance.

[0015] The outer peripheral visible surface portion 49 is continuous with the exterior visible surface portion 46 at its exterior end portion, and is continuous with the interior visible surface portion 47 at its interior end portion. The outer peripheral visible surface portion 49 has an exterior portion 491 that is continuous with the exterior visible surface portion 46, an extension portion 492 that extends from the exterior portion 491 to the inner peripheral side, and an interior portion 493 that extends from the extension portion 492 toward the interior side of the room. A weatherstripping material 62 that abuts against the lower frame 22 is provided at the outer peripheral end portion of the extension portion 492. The exterior portion 491 is covered on the outer surface by an acrylic laminate 8 that is continuous with the exterior visible surface portion 46, and the exterior surfaces of the extension portion 492 and the interior portion 493 are exposed to the outside. Here, when the resin screen 3 is in the opening-closing position, the extension portion 492 and the interior portion 493 are disposed opposite the lower frame 22 in the Z-axis direction, so that the extension portion 492 and the interior portion 493 are not exposed to the outside and do not affect the external design of the vertical sliding window 1. However, when the resin screen 3 is in the opening-opening position, the extension portion 492 and the interior portion 493 are disposed in a position moved in the outward direction relative to the lower frame 22, so that the extension portion 492 and the interior portion 493 are exposed to the outside and may affect the external design of the vertical sliding window 1. For this reason, the extension portion 492 and the interior portion 493 are formed of unused resin material rather than recycled resin material so that the external design is not deteriorated even if they are exposed to the outside. That is, at least the exposed portion of the outer peripheral side visible surface portion 49 that is exposed to the outside is made of unused resin material.

[0016] In this lower frame 42, the pressing edge 51, the receiving portion 481, and the portion of the inner peripheral side projection surface portion 48 located between the pressing edge 51 and the receiving portion 481 form a surface material holding groove 401 that holds the edge portion 301 of the surface material 30, and all of the portions of the base material of the lower frame 42 that are exposed to the outside are made of unused resin material. In addition, the lower frame 42 has a plurality of partition pieces 483 that are continuous with the portion of the inner peripheral side projection surface portion 48 that is made of recycled resin material and the outer peripheral side projection surface portion 49, and the partition pieces 483 are made of recycled resin material as described above, and form a plurality of hollow portions 402 between the inner peripheral side projection surface portion 48 and the outer peripheral side projection surface portion 49.

[0017] [Variations] In the above embodiment, the exterior visible surface portion 46 is configured by covering the main body layer 461 formed of unused resin material from the outside with the acrylic laminate 8, but this is not limiting, and for example, as in the first modified example shown in Fig. 4, the main body layer 461 may be formed of a recycled resin material, and in this case, the exterior portion 491 of the outer peripheral side visible surface portion 49, the exterior of which is covered with the acrylic laminate 8, may also be formed of a recycled resin material. Even when the main body layer 461 and the exterior portion 491 are formed of recycled resin material in this way, the part is covered with the acrylic laminate 8, so the recycled resin material part is not exposed to the outside, and the desired appearance can be configured by applying decoration to the acrylic laminate 8.

[0018] In the above embodiment, the receiving portion 481 is bonded to the face material 30, but as in the second modified example shown in FIG. 5, for example, a contact body 482 that contacts the indoor surface 30B of the face material 30 may be provided on the receiving portion 481, and the receiving portion 481 may not be bonded to the face material 30. In this case, the receiving portion 481 may be formed of a recycled resin material without having a portion formed of unused resin material. Even if formed in this way, the receiving portion 481 does not bond to the face material 30, so by forming it from a recycled resin material, it is possible to assume that the receiving portion 481 contains a substance that inhibits adhesion. Furthermore, by providing the contact body 482, it is possible to suppress exposure of the recycled resin material to the outside.

[0019] In the above embodiment, the outer surfaces (surfaces) of the exterior visible surface 46, the exterior side 491 of the outer peripheral visible surface 49, and the edge base material 52 are covered with an acrylic laminate 8 as a surface layer, but this is not limited to the above, and for example, when weather resistance is not required, the acrylic laminate 8 may be omitted. In the above embodiment, the face material 30 is made of laminated glass, but the present invention is not limited to this and may be made of a face material made of a single glass plate. In the above embodiment, the receiving portion 481 is formed from a recycled resin material within a predetermined range, but this is not limiting, and for example, the entire receiving portion 481 may be formed from a virgin resin material. In the above embodiment, the interior facing surface portion 47 is formed only from unused resin material, but a PVC laminate 8B or an acrylic laminate 8 may be provided as a surface layer that covers the outer surface of this from the interior side. Furthermore, when such a surface layer is provided, a main layer that is covered by the surface layer from the interior side may be formed using recycled resin material instead of unused resin material. In the above embodiment, the partition piece 483 is made of recycled resin material, but it may be made of virgin resin material. In addition, if the strength of the resin frame 40 can be maintained without the partition piece 483, the partition piece 483 may be omitted. In the above embodiment, a seal material 62 is provided on the extension portion 492 of the outer peripheral side visible surface portion 49 of the resin frame material 40, but this is not limited to the above, and this configuration may be omitted if the desired airtightness, watertightness, insulation, etc. can be achieved without the seal material 62.

[0020] In the above embodiment, a vertical sliding window 1 has been described as the building material, but it may also be a casement window such as a horizontal sliding window, a projection window or a tilt-down window, or a sliding window such as a double sliding window, a single sliding window or a sash window.

[0021] [Summary of the invention] (1) The resin shoji screen of the present invention is a resin shoji screen that is arranged within a frame body so as to be able to be opened and closed, and comprises a face material and a resin frame material that is arranged along the edge of the face material, and the resin frame material has an exterior facing surface portion, an interior facing surface portion, an inner peripheral facing surface portion that is arranged between the exterior facing surface portion and the interior facing surface portion in the facing direction, and an outer peripheral facing surface portion that is located between the exterior facing surface portion and the interior facing surface portion and on the outer peripheral side of the inner peripheral facing surface portion, and is characterized in that at least the portion of the inner peripheral facing surface portion that faces the edge of the face material in the in-plane direction is made of recycled resin material, and at least the exposed portion of the outer peripheral facing surface portion that is exposed to the outside is made of unused resin material. According to the resin shoji screen of the present invention, at least the exposed portion of the outer peripheral visible surface is made of unused resin material, so that regardless of whether the resin shoji screen is placed in the opening open position or the opening closed position relative to the frame body, the recycled resin material at the outer peripheral visible surface will not be exposed to the outside, thereby improving the external design. In addition, at least the portion of the inner peripheral visible surface that faces the edge of the panel material is made from recycled resin material, so the material cost of the resin frame material can be reduced, and the cost of the resin screen can be reduced. (2) In the resin shoji screen of the present invention, all of the portions of the resin frame material exposed to the outside may be made of virgin resin material. With this configuration, even if recycled resin material is used for at least the portion of the inner peripheral visible surface of the resin frame that faces the edge of the face material, the resin frame will appear to be made of unused resin material, thereby improving the appearance design. (3) In the resin shoji screen of the present invention, the face material is constructed by interposing a spacer between the edges of at least two panel plates, and the inner peripheral projection surface portion has a receiving portion extending inward and facing the face material in the projection direction, and the receiving portion may have a portion formed of recycled resin material within a range that does not protrude inward beyond the spacer. With this configuration, it is possible to increase the portion made of recycled resin materials within an area that is not visible from the outside, and it is possible to reduce the cost of the resin screen by reducing the material cost of the resin frame. (4) In the resin shoji screen of the present invention, the receiving portion may have a portion made of unused resin material, and the portion made of unused resin material may be bonded to the face material. According to this configuration, the portion of the receiving portion that is bonded to the face material is made of unused resin material, and therefore the adhesive strength can be increased compared to, for example, a case in which this portion is made of recycled resin material. (5) In the resin shoji screen of the present invention, the exterior-facing surface portion may be provided with a surface layer that covers the main layer from the exterior side. With this configuration, the aforementioned surface layer is provided on the exterior-facing surface, and by using a surface layer that is weather-resistant and has the desired decoration, a resin shoji screen can be constructed with a resin frame material that has the desired appearance and characteristics on the outside. (6) In the resin shoji screen of the present invention, the interior facing surface may be formed from unused resin material. With this configuration, it is possible to prevent the recycled resin material from being exposed to the inside of the room, and also to prevent the formation of uneven thickness portions in the main body layer that constitutes the base material portion of the interior visible surface, which would result in an unstable shape, compared to, for example, a case in which a surface layer is provided on the interior visible surface. (7) In the resin shoji screen of the present invention, at least one of the exterior facing surface portion and the interior facing surface portion may be made of unused resin material, or may be made of a main body layer formed of recycled resin material and a surface layer covering the surface of the main body layer. With this configuration, when at least one of the exterior facing surface and the interior facing surface is made of unused resin material, the portion made of unused resin material rather than recycled resin material will be visible from at least one of the exterior and interior sides, thereby improving the external design of the resin shoji screen that uses resin frame material that uses recycled resin material.Furthermore, compared to, for example, when at least one of the exterior facing surface and the interior facing surface is made of a main body layer and a surface layer, it is possible to prevent the formation of uneven thickness portions in the main body layer that makes up the base material portion of the interior facing surface, resulting in an unstable shape. Furthermore, when at least one of the exterior facing surface and the interior facing surface is composed of a main body layer formed from recycled resin material and a surface layer covering the surface of the main body layer, the material costs for the main body layer can be reduced and any surface layer can be seen from at least one of the exterior and interior sides, thereby improving the external design of resin shoji screens that use resin frame materials made from recycled resin materials. (8) In the resin shoji screen of the present invention, the inner peripheral side projected surface portion has a partition piece portion that is connected to a portion that faces the edge portion of the panel material in the in-plane direction and the outer peripheral side projected surface portion and forms a hollow portion between that portion and the outer peripheral side projected surface portion, and the partition piece portion may be made of recycled resin material. With this configuration, the strength of the resin frame material can be increased by providing a partition piece and forming a hollow portion, and the portion of the resin frame material made from recycled resin material can be increased, thereby reducing the cost of the resin shoji screen. (9) The resin frame material of the present invention is a resin frame material arranged along the edge of a surface material, and has an exterior facing surface portion, an interior facing surface portion, an inner peripheral facing surface portion arranged between the exterior facing surface portion and the interior facing surface portion in the facing direction, and an outer peripheral facing surface portion arranged between the exterior facing surface portion and the interior facing surface portion and on the outer peripheral side of the inner peripheral facing surface portion, wherein at least a portion of the inner peripheral facing surface portion that can face the edge of the surface material in the in-plane direction is made of recycled resin material, and at least a portion of the outer peripheral facing surface portion that is exposed to the outside is made of unused resin material. According to the resin frame material of the present invention, it is possible to form a resin frame material that can exert the same effect as the resin shoji screen of the present invention described above.
