Description

[Technical field]

[0001] The present invention relates to a composite window frame and / or composite frame in which glass is fixed with metal and resin frames within a rectangular framed window. [Background technology]

[0002] In recent years, composite window frames that combine a metal frame with a resin frame attached to the interior side of the metal frame have been increasingly used as window frames that are attached to window openings in buildings in order to prevent condensation in winter while maintaining the thermal insulation properties of the window frame (see, for example, Patent Document 1). In such composite window frames, the frame of a shoji screen is also made of a metal frame and a resin frame to fix the glass for the same reason. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-107631 Summary of the Invention [Problem to be solved by the invention]

[0004] In such composite window frames and / or composite frames consisting of metal members such as a metal frame or metal frame and resin members such as a resin frame or resin frame, the resin frame is fixed to the metal members with fasteners such as screws, and in order to improve the design, a resin fastener cover is fitted to the front side of the resin member such as the resin frame or resin frame to cover the heads of the fasteners so that they are not visible from the outside.

[0005] Generally, resin has a thermal expansion coefficient 4 to 5 times larger than that of metal, but resin members such as resin frames and resin frames fixed to metal members such as metal frames and metal frames with fasteners such as screws are limited in contraction and expansion due to temperature changes. On the other hand, since a resin fastener cover is fitted and attached to a resin member, contraction and expansion due to temperature changes are greater than that of a metal member or a resin member fixed to a metal member.

[0006] Therefore, in winter, the resin fastener cover shrinks more than the metal member and the resin member fixed to the metal member, and in particular, in the case of a fastener cover that hides the head of the fastener that fastens the resin member to the metal member that constitutes the vertical frame or vertical stile, the gap between the upper end of the fastener cover and the upper frame or upper stile is located close to eye level and is noticeable, resulting in a problem of poor design. Also, in summer, the resin fastener cover expands more than the metal member and the resin member fixed to the metal member, and its longitudinal end interferes with the upper frame or upper stile, making it impossible to absorb the expansion, and there is a risk that the fastener cover will come loose.

[0007] The present invention has been made to solve these problems, and its object is to provide a composite window frame and / or composite frame that prevents the gap from being seen from the outside, improving the design, even if the resin fastener cover shrinks due to temperature change and the gap between the upper end of the fastener cover and the upper frame or upper stile becomes large, and that will not come loose even if the fastener cover expands due to temperature change. [Means for solving the problem]

[0012] <Overview of vertical sliding windows and composite window frames 1> FIG. 1 is a vertical cross-sectional view of a vertical sliding window employing a shoji frame structure according to an embodiment of the present invention.

[0013] A vertical sliding window is a well-known window in which a shoji screen 2 slides out to the outside (outdoors) to be opened or closed by a pair of upper and lower stays (not shown) provided between an upper frame 1a and a lower frame 1b that constitute a composite window frame 1 as shown in FIG. 1, and an upper frame 2a and a lower frame 2b that constitute a shoji screen 2. The composite window frame 1 is composed of an upper frame 1a, a lower frame 1b, and left and right vertical frames 1c that have a metal frame 1a1, a metal lower frame 1b1, and metal vertical frames 1c1 on both the left and right sides, which are framed in a square shape and are attached to the window opening of a building as shown in FIG. 1, FIG. 8, etc., and are composed of an upper frame 1a, a lower frame 1b, and left and right vertical frames 1c that have a resin upper frame 1a2, a resin lower frame 1b2, and resin frames 1a2-1c2 of the resin vertical frames 1c2 on both the left and right sides. The metal frames 1a1 to 1c1 are formed from an extruded material such as aluminum, and the resin frames 1a2 to 1c2 are formed from an extrusion material such as vinyl chloride or acrylic resin.

[0014] <Frame structure of Shoji 2> As shown in Fig. 1, the shoji screen 2 of the first embodiment slides open and closes in an opening of a composite window frame 1 made up of an upper frame 1a, a lower frame 1b, and vertical frames 1c on both the left and right sides, and is configured to support double-glazing glass, etc., with an upper frame 2a, a lower frame 2b, and vertical frames 2c on the left and right sides. Note that the characteristics of the frame structure of the shoji screen 2 of the first embodiment are not related to double-glazing, so the double-glazing glass is not shown in the drawings.

[0015] (Upper stile 2a) As shown in Figures 1 and 2, the upper frame 2a is composed of a metal upper frame 2a1 as the metal member of the present invention molded from aluminum or the like, a metal frame 2a2 for the upper frame as the fixed part, a resin frame 2a3 for the upper frame as the resin member main body part constituting the resin member of the present invention molded from polyvinyl chloride, acrylic resin, or the like, and a screw cover 2a4 for the upper frame as a fixing device cover.

[0016] As shown in FIG. 2, the metal upper frame 2a1 has an exterior upright portion 2a11 that stands upright at the exterior end, a glass upper end pressing portion 2a12 that presses the upper end of the hanging double-glazed glass (not shown) from the outside of the room at the exterior end, and a hollow first hollow portion 2a13 and a second hollow portion 2a14. It also has an engagement groove portion 2a15 between the first hollow portion 2a13 and the second hollow portion 2a14 into which an engagement portion 2a22 described later of the metal frame for the upper frame 2a2 fits, and an engagement claw portion 2a16 into which an engagement portion 2a34 described later of the plastic frame for the upper frame fits.

[0017] As shown in Figure 2, the metal frame for the upper frame 2a2 is a component that fits into the metal upper frame 2a1 to press the upper end of the double-glazed glass (not shown) from the inside of the room after the plastic frame for the upper frame 2a3 is fixed with screws 4 as fixing devices, and is provided with a screw hole installation piece 2a21 having multiple screw holes at predetermined intervals in the finding direction into which the screws 4 screw, and an engagement portion 2a22 that fits into the engagement groove portion 2a15 of the metal upper frame 2a1 of the metal frame for the upper frame 2a2.

[0018] The resin frame for the upper frame 2a3 is formed by cutting a shape formed by extruding synthetic resin such as polyvinyl chloride or acrylic resin, and is a component that is attached to the metal upper frame 2a1 after being fixed to the metal frame for the upper frame 2a2 with screws 4 as shown in FIG. 2. The resin frame for the upper frame 2a3 has screw hole installation surfaces 2a31 in which screw holes through which the screws 4 pass are provided at the same intervals as the screw hole installation pieces 2a21 of the metal frame for the upper frame 2a2, an intermediate surface 2a32 whose tip abuts against the underside of the metal upper frame 2a1, an indoor-side exposed surface 2a33 exposed to the room, and a vertical surface of the indoor-side exposed surface 2a33 that slopes from the upper end of the vertical surface toward the metal upper frame 2a1 and engages the metal upper frame 2a1. It has an engaging portion 2a34 that engages with the claw portion 2a16, a first engaged portion 2a35 for the cover that extends downward from the tip of the screw hole mounting surface 2a31 and engages with the first engaging portion 2a41 of the upper frame screw cover 2a4, a second engaged portion 2a36 for the cover provided at the lower end of the intermediate surface 2a32 and engaging with the second engaging portion 2a42 of the upper frame screw cover 2a4, a third engaged portion 2a37 for the cover provided at the lower end of the indoor exposed surface 2a33 and engaging with the third engaging portion 2a43 of the upper frame screw cover 2a4, and a relay surface 2a38 that is continuous with the screw hole mounting surface 2a31 and extends from the second engaged portion 2a36 for the cover to the indoor exposed surface 2a33.

[0019] The upper frame screw cover 2a4 is attached to the lower part of the upper frame resin frame 2a3 so as to hide the head of the screw 4 that fixes the upper frame metal frame 2a2 and the upper frame resin frame 2a3, and the first engaging part 2a41, the second engaging part 2a42, and the third engaging part 2a43 that engage with the first cover engaged part 2a35, the second cover engaged part 2a36, and the third cover engaged part 2a37 of the upper frame resin frame 2a3 are provided on the upper surface side (rear surface side) from the main body part 2a44. Also, the longitudinal direction (depth direction in FIG. 1, left and right direction in FIG. 3) end part 2a45 of the upper frame screw cover 2a4 is up to the upper part of the main body part 2c44 of the vertical frame screw cover 2c4 described later (upper relay part 3b of the cover upper end hiding member 3 described later) as shown in FIG. 5(b). Therefore, the longitudinal end 2a45 of the upper frame screw cover 2a4 is configured so as not to be seen from the outside. The longitudinal end 2b45 of the lower frame screw cover 2b4 is also configured so as not to be seen from the outside, as shown in FIG.

[0020] (Lower stile 2b) As shown in Figure 1, the lower frame 2b is also composed of a metal lower frame 2b1 as the metal member of the present invention molded from aluminum or the like, a metal frame for the lower frame 2b2 as the fixed part, a resin frame for the lower frame 2b3 as the resin member main body constituting the resin member of the present invention molded from polyvinyl chloride, acrylic resin, or the like, and a screw cover for the lower frame 2b4 as a fixing device cover.

[0021] The metal lower frame 2b1, metal frame for the lower frame 2b2, plastic frame for the lower frame 2b3 and screw cover for the lower frame 2b4 which constitute the lower frame 2b are respectively formed in a shape which is approximately an inverted upside-down version of the metal upper frame 2a1, metal frame for the upper frame 2a2, plastic frame for the upper frame 2a3 and screw cover for the upper frame 2a4 which constitute the upper frame 2a, as is clear from Figure 1, and are assembled in an inverted state (excluding the cover upper end hiding member 3).

[0022] (Stile 2c) 3, the vertical frame 2c is configured with a metal vertical frame 2c1 which is a metal member formed from aluminum or the like, a metal frame 2c2 for the vertical frame as a fixed part, a resin frame 2c3 for the vertical frame as a resin member main body constituting the resin member of the present invention, a screw cover 2c4 for the vertical frame as a fixing tool cover, and a cover upper end hiding member 3 described later. Note that, in this specification, the vertical frame 2c on the right side of the interior is described as an example, but the vertical frame on the left side of the interior is formed in a shape obtained by mirror-inverting the vertical frame 2c, and is assembled in the mirror-inverted state.

[0023] As shown in Figure 3, the metal vertical frame 2c1 has an exterior protruding portion 2c11 that protrudes outward at the exterior end, a glass lateral end pressing portion 2c12 that protrudes inward at the exterior end and presses the lateral end of the double-glazed glass (not shown) from the outside of the room, and a hollow first hollow portion 2c13 and a second hollow portion 2c14.It also has an engagement groove portion 2c15 between the first hollow portion 2c13 and the second hollow portion 2c14 into which the engagement portion 2c22 of the metal frame for the vertical frame 2c2, described later, fits, and an engagement claw portion 2c16 into which the engagement portion 2c34 of the plastic frame for the vertical frame 2c3, described later, fits.

[0024] As shown in Figure 3, the metal frame for the vertical frame 2c2 is fitted into the metal vertical frame 2c1 to form the vertical frame 2c after the resin frame for the vertical frame 2c3 is fixed with fastening devices such as screws 4. The metal frame for the vertical frame 2c2 has a screw hole installation piece 2c21 with a plurality of screw holes at predetermined intervals into which the screws 4 screw, and a fitting portion 2c22 that fits into the fitting groove portion 2c15 of the metal vertical frame 2c1 of the metal frame for the vertical frame 2c2.

[0025] The resin frame for the vertical frame 2c3 is extruded from a synthetic resin such as polyvinyl chloride or acrylic resin, similar to the resin frame for the upper frame 2a3 and the resin frame for the lower frame 2b3, and is attached to the metal vertical frame 2c1 after the metal frame for the vertical frame 2c2 is connected with screws 4 as shown in FIG. 3. The resin frame for the vertical frame 2c3 has a screw hole installation surface 2c31 with a plurality of screw holes provided at a predetermined interval, an intermediate surface 2c32 whose tip abuts against the front surface of the metal vertical frame 2c1, an indoor exposed surface 2c33 exposed to the room, and a metal vertical frame 2c34 extending from the right end of the horizontal surface of the indoor exposed surface 2c33 to the right end of the metal vertical frame 2c1. It has an engaging portion 2c34 that inclines toward 2c1 and engages with the engaging claw portion 2c16 of the metal vertical frame 2c1, a first engaged portion 2c35 for the cover that extends leftward from the exterior end of the screw hole installation surface 2c31 and engages with the first engaging portion 2c41 of the vertical frame screw cover 2c4, a second engaged portion 2c36 for the cover that is provided at the left end of the intermediate surface 2c32 and engages with the second engaging portion 2c42 of the vertical frame screw cover 2c4, and a third engaged portion 2c37 for the cover that is provided at the left end of the indoor exposed surface 2c33 and engages with the third engaging portion 2c43 of the vertical frame screw cover 2c4.

[0026] In addition, since the resin frame 2c3 for the vertical frame has the cover upper end concealing member 3 attached to its upper end, two fitting holes 2c38a are provided at the top of the relay surface 2c38, which is continuous with the screw hole installation surface 2c31 between the second engaged portion 2c36 for the cover and the third engaged portion 2c37 for the cover and extends to the indoor exposed surface 2c33, into which two fitting portions 3a1 described later of the cover upper end concealing member 3 are inserted and fitted.

[0027] The vertical frame screw cover 2c4 is attached to the inside of the vertical frame made of resin 2c3, i.e., on the left side in Figure 3, so as to hide the heads of the screws 4 that fix the vertical frame made of resin 2c3 to the vertical frame metal 2c2. On the vertical frame 2c side, a first engagement portion 2c41, a second engagement portion 2c42 and a third engagement portion 2c43 that engage with the first cover engaged portion 2c35, the second cover engaged portion 2c36 and the third cover engaged portion 2c37 of the vertical frame resin 2c3 are respectively provided from the main body portion 2c44, and the upper end portion, which is the longitudinal end portion 2c45 (up and down direction in Figure 1, depth direction in Figure 3) of the vertical frame screw cover 2c4, is configured to be hidden by the cover upper end hiding member 3 as shown in Figure 5(b) described later, even if it expands and contracts due to temperature changes. The other vertical frame screw cover 2c4 has a lower end portion, which is a longitudinal end portion 2c45, placed on the upper surface of the lower frame screw cover 2b4 as shown in FIG.

[0028] (Cover top end hiding part 3) The cover upper end hiding member 3 is molded from resin into the shape shown in Figures 4(a), (b), and 5(a), and is composed of a hiding member fixing part 3a that extends in the vertical direction and is fixed to the relay surface 2c38 of the resin frame 2c3 for the vertical frame as shown in Figures 3 and 5(b), a relay part 3b that extends horizontally from the upper end of the hiding member fixing part 3a and covers the upper part of the upper end of the vertical frame screw cover 2c4, and a cover upper end hiding part 3c that hangs down from the tip of the relay part 3b to face the hiding member fixing part 3a, and the like. The hiding member fixing part 3a is provided with two fitting parts 3a1 that are spaced apart in the vertical direction and fit respectively into two fitting holes 2c38a in the relay surface 2c38 of the resin frame 2c3 for the vertical frame.

[0029] On both the left and right sides of the cover upper end hiding portion 3c in Figures 4(a) and (b), there is provided an end protrusion 3c1 that protrudes toward the hiding member fixing portion 3a, and while it overlaps and hides the upper end of the vertical frame screw cover 2c4, only the tip of the end protrusion 3c1 on the outside of the room comes into contact with the upper end of the vertical frame screw cover 2c4 so as to reduce the contact area as shown in Figure 3.

[0030] In addition, when the cover upper end hiding member 3 is attached to the upper end of the resin frame 2c3 for the vertical frame, the end hiding portion 3c is formed so as to overlap the upper end of the vertical frame screw cover 2c4 by a predetermined length L in the vertical direction, as shown in Figure 5(b).

[0031] The specified length L is determined taking into consideration the shrinkage length of the vertical frame screw cover 2c4 so that, because the resin vertical frame screw cover 2c4 expands and contracts more with temperature changes than the metal vertical frame 2c1 or the resin vertical frame 2c3 which is fixed to the metal vertical frame 2c2 made of metal with screws 4 and has limited thermal shrinkage and thermal expansion, even if the vertical frame screw cover 2c4 shrinks more than the metal vertical frame 2c1 or the resin vertical frame 2c3 in winter, for example, and the gap between the upper end of the vertical frame screw cover 2c4 and the upper frame screw cover 2a4 becomes larger, the upper end of the vertical frame screw cover 2c4 overlaps and is hidden by the lower end of the cover upper end hiding portion 3c, and the shrunken upper end of the vertical frame screw cover 2c4 is not visible from the outside.

[0032] Incidentally, the state shown in FIG. 5(b) shows a state other than summer and winter. In summer, the vertical frame screw cover 2c4 extends beyond the metal vertical frame 2c1 and the resin vertical frame 2c3 fixed with screws 4 to the metal vertical frame 2c2 and the metal vertical frame 2c2, and the upper end of the vertical frame screw cover 2c4 approaches the underside of the relay portion 3b of the cover upper end hiding member 3, thereby ensuring a predetermined gap S of a length that does not allow the upper end of the vertical frame screw cover 2c4 to interfere with the underside of the relay portion 3b.

[0033] (End sealing member 5) The end blocking member 5 is a member configured in the shape shown in Figures 6(a) to (c), and is fixed with screws 6 to the upper and lower parts of the metal vertical frame 2c1 of the vertical frame 2c as shown in Figures 7 to 9, so as to block both ends, which are the longitudinal ends 2a39 of the upper frame resin frame 2a3 and both ends, which are the longitudinal ends 2b39 of the lower frame resin frame 2b3.

[0034] That is, the end sealing member 5 is formed from resin into a shape as shown in Figures 6(a) to (c), and includes end sealing surfaces 5a that abut or are close to both longitudinal ends of the upper frame resin frame 2a3 or the lower frame resin frame 2b3 to seal said ends, screw shaft insertion portions 5b into which the shafts of the screws 6 are inserted, recesses 5c into which the heads of the screws 6 fit, and recesses 5d into which the heads of the screws 6 fit, and recesses 5e into which the heads of the screws 6 fit, and recesses 5f into which the heads of the screws 6 fit, and recesses 5g ... It is equipped with a frame indoor side covering surface 5d which has the same cross-sectional shape and is continuous with the indoor exposed surfaces 2a33, 2b33, a horizontal engaging claw fitting portion 5e into which the engaging claw portion 2a16, 2b16 (see Figures 1 and 2) of the metal upper frame 2a1 or the metal lower frame 2b1 which are metal members extending in the horizontal direction fit, a vertical engaging claw fitting portion 5f into which the engaging claw portion 2c16 (see Figure 3) of the metal vertical frame 2c1 which is a metal member extending in the vertical direction fits, and a vertical member opposing surface 5g which faces the longitudinal end 2c39 of the resin frame 2c3 for the vertical frame.

[0035] In order to close both ends of the upper frame resin frame 2a3 and the lower frame resin frame 2b3 in the longitudinal direction with the end blocking member 5 thus configured, as shown in Fig. 8 and Fig. 9, the upper frame 2a and the lower frame 2b are fixed to the upper and lower parts of the metal vertical frame 2c1 that face both ends of the upper frame resin frame 2a3 and the lower frame resin frame 2b3 in the longitudinal direction with screws 6, and then the upper frame 2a and the lower frame 2b are assembled to the vertical frame 2c, and both ends of the upper frame resin frame 2a3 and the lower frame resin frame 2b3 in the longitudinal direction are blocked by the end blocking member 5 fixed to the upper and lower parts of the metal vertical frame 2c1 as shown in the longitudinal cross-sectional view of Fig. 7. Also, as shown in Fig. 7 and Fig. 8, the vertical frame resin frame 2c3 is placed between the vertical member facing surfaces 5g of the upper and lower end blocking members 5. Therefore, the indoor exposed surface 2c33 against which the airtight material 1c21 provided on the resin vertical frame 1c2 abuts does not extend to the upper or lower end of the shoji screen, but the frame room interior side covering surface 5d of the end sealing member 5 extends continuously to the upper and lower end of the shoji screen, and the airtight material 1c21 abuts against the frame room interior side covering surface 5d and is continuous with the airtight materials 1a21, 1b21 of the upper and lower frames.

[0036] <Main effects of the frame structure of the shoji screen 2 in the embodiment> As explained above, in the shoji screen 2 that employs a composite frame which is an embodiment of the composite window frame and / or composite frame of the present invention, the vertical frame 2c comprises the metal vertical frame 2c1 and the metal vertical frame 2c2, which are metal members formed from aluminum or the like, and the resin vertical frame 2c3 and the vertical frame screw cover 2c4, which are resin members, and the resin vertical frame 2c3 is fixed to the metal vertical frame 2c2 with screws 4 and attached to the metal vertical frame 2c1 together with the metal vertical frame 2c2, while the vertical frame screw cover 2c4 is attached to the resin vertical frame 2c3 so as to hide the screws 4, and the resin vertical frame 2c3 is further provided with a cover upper end hiding member 3 which overlaps with the upper end of the vertical frame screw cover 2c4 by a predetermined length L in the vertical direction and hides the upper end of the vertical frame screw cover 2c4.

[0037] For this reason, the resin vertical frame screw cover 2c4 shrinks and expands more due to temperature changes than the resin vertical frame 2c3 which is fixed with screws 4 to the metal vertical frame 2c1 and the metal vertical frame 2c2. Even if, for example, in winter the vertical frame screw cover 2c4 shrinks more than the metal vertical frame 2c1 and the resin vertical frame 2c3 and the gap between the upper end of the vertical frame screw cover 2c4 and the upper frame screw cover 2a4 becomes larger, the upper end of the vertical frame screw cover 2c4 is hidden by the cover upper end hiding member 3 which overlaps the upper end of the vertical frame screw cover 2c4 by a predetermined length L, so that the gap is not visible from the outside and the design can be improved. Furthermore, a predetermined gap S is secured so that the upper end of the vertical frame screw cover 2c4 does not interfere with the underside of the relay portion 3b of the cover upper end hiding member 3, so that it can also accommodate expansion of the vertical frame screw cover 2c4 due to heat in the summer, for example.

[0038] In addition, in the shoji screen 2 that employs the composite frame of an embodiment of the present invention, end blocking members 5 are provided at the upper and lower parts of the metal vertical frame 2c1 of the vertical frame 2c to block both longitudinal ends of the upper frame resin frame 2a3 and the lower frame resin frame 2b3.

[0039] As a result, both longitudinal ends of the resin frame for the upper frame 2a3 and the resin frame for the lower frame 2b3 do not come into direct contact with the sides of the metal vertical frame 2c1, and even if the metal vertical frame 2c1 is cooled by outside air, the cold air from the metal vertical frame 2c1 is prevented from being transmitted to the resin frame for the upper frame 2a3 and the resin frame for the lower frame 2b3, thereby improving the insulation properties of the shoji screen 2.

[0040] In addition, the end covering member 5 has a frame interior side covering surface 5d which is continuous with the indoor exposed surface 2a33, 2b33, which is the indoor side surface of the upper frame resin frame 2a3 or the lower frame resin frame 2b3, and which has the same cross-sectional shape as the indoor exposed surface 2a33, 2b33, which is the indoor side of the upper frame resin frame 2a3 or the lower frame resin frame 2b3, and which continues with the indoor exposed surface 2c33 of the vertical frame resin frame 2c3 to the upper and lower ends of the shoji screen.Therefore, the airtight material 1c21 provided on the resin vertical frame 1c2 abuts against the frame interior side covering surface 5d and is continuous with the airtight materials 1a21, 1b21 of the upper and lower frames, thereby improving airtightness performance and insulation performance.

[0041] In the above embodiment, a cover upper end hiding member 3 for hiding the upper end of the vertical frame screw cover 2c4 is provided on the vertical frame resin frame 2c3, which is the main body of the resin member extending vertically. However, the present invention is not limited to this, and it is of course also possible to provide a cover upper end hiding member 3 for hiding the upper end of the vertical frame screw cover 2c4 on the underside (bottom surface) of the upper frame screw cover 2a4, which hides the heads of the screws 4 that fix the upper frame metal frame 2a2 and the upper frame resin frame 2a3 in the upper frame 2a.

[0042] In addition, in the above embodiment, the metal members are the metal upper frame 2a1, the metal lower frame 2b1, and the metal vertical frame 2c1, and the metal frame for the upper frame 2a2, the metal frame for the lower frame 2b, and the metal frame for the vertical frame 2c2, which fit into the metal members as the fixed parts, are described as being separate parts. However, the present invention is not limited to this, and the fixed parts do not have to be metal frames, but may be fixed parts fixed to the metal upper frame 2a1, the metal lower frame 2b1, and the metal vertical frame 2c1 by fasteners, and of course a portion of 2a1 to 2c1 of each metal frame member may also be the fixed part.

[0043] In addition, in the above embodiment, a shoji screen 2 using a composite frame has been described as an example of a composite window frame and / or composite frame according to the present invention, but the present invention is not limited to this, and it goes without saying that a composite window frame according to the present invention may be used on the composite window frame 1 side.

[0044] In addition, in the description of the embodiment, the shoji screen 2 and composite window frame 1 of the present invention have been used in a vertical sliding window to be attached to a window opening of a building, but the present invention is not limited to this and can be used in other casement windows such as horizontal sliding windows, vertical axis rotating windows, horizontal axis rotating windows, and outward-tilting windows, as well as other composite window frames such as sliding windows and fixed windows, and even composite window frames for interior fittings.
