[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 4 show one embodiment of an opening device of the present invention. This opening device is applied to a sliding window with a shutter for a house, and as shown in Figures 1 and 2, it comprises a frame 12 attached to a structural opening 11, an outer shoji screen 13a and an inner shoji screen 13b provided in the frame 12 in a sliding manner so as to be able to open and close freely, and a shutter 8 provided on the exterior side of the frame 12.

[0008] As shown in Figures 1, 2 and 6, the frame 12 is constructed by framing an upper frame 14, a lower frame 15 and left and right vertical frames 1,1 made of extruded aluminum alloy in a rectangular shape, and by erecting a window upper frame 16 between the left and right vertical frames 1,1 below the upper frame 14. As shown in Figure 1, an outer shoji screen 13a and an inner shoji screen 13b are installed between the upper window frame 16 and the lower window frame 15, and a shutter box 2 containing a winding section 18 for winding up a shutter curtain 17 is installed between the left and right vertical frames 1, 1 between the upper window frame 14 and the upper window frame 16. The shutter box 2 is covered with a cover 3 attached to the outside of the room. The shutter curtain 17 is made up of a large number of steel plate-shaped slats 9 connected together vertically, and is fire-resistant.

[0009] As shown in Figure 2, the vertical frame 1 has an outer peripheral side wall 5 and an inner peripheral side wall 36, with a hollow portion 4 between the outer peripheral side wall 5 and the inner peripheral side wall 36. As shown in Figure 5, the upper part of the vertical frame 1 has the hollow portion 4 cut out from the inner peripheral side so that only the outer peripheral side wall 5 remains. A metal reinforcing plate 19 is attached to the inner peripheral side of the outer peripheral side wall 5 at the top of the vertical frame 1, and the reinforcing plate 19 is provided with a screw-receiving portion 20 for screwing the shutter box 2. As shown in Figure 6, the shutter box 2 is attached between the outer peripheral side walls 5, 5 of the left and right vertical frames 1, 1 to which the reinforcing plate 19 is attached. In this way, by cutting out the hollow portion 4 at the top of the vertical frame 1 and attaching the shutter box 2 between the outer side walls 5, 5 of the left and right vertical frames 1, 1, the width of the shutter box 2 and the slats 9 that make up the shutter curtain 17 is made larger than the conventional one (Figure 10) described below by the width of the hollow portions 4, 4 of the left and right vertical frames 1, 1.

[0010] As shown in Figures 1 and 6, the shutter box 2 is made of metal plates and is shaped like a box with an open exterior, and houses a winding unit 18 that winds up the shutter curtain 17 inside the shutter box 2. The shutter box 2 also contains a motor (not shown) that rotates the winding unit 18, and the shutter curtain 17 is raised and lowered electrically by operating a remote control inside the room. As shown in Figure 1, the shutter box 2 has mounting pieces 21 formed on the top and bottom of both the left and right ends. As shown in Figure 6, the shutter box 2 is placed from the outside of the room between the left and right vertical frames 1, 1 between the top frame 14 and the window top frame 16, and the mounting pieces 21 are attached by screwing them into screw-receiving portions 20 formed on the reinforcing plates 19 of the left and right vertical frames 1, 1 with screws 22 from the outside of the room.

[0011] As shown in Figure 4, the shutter box 2 has a front portion 6 that protrudes outside the room further than the vertical frame 1, and the wiring 7 to the shutter box 2 protrudes to the side from the outer side wall 5 of the vertical frame 1 at the front portion 6 of the shutter box 2. The cover 3 that covers the shutter box 2 from the outside of the room has a front portion 23 made of a metal plate and side cover portions 24 made of resin, and the side cover portions 24 extend outward beyond the outer peripheral side wall 5 of the vertical frame 1 to form a space 25 for passing the wiring 7. Therefore, when the cover 3 is attached, the wiring 7 that protrudes to the side from the vertical frame 1 is covered from the outer periphery by the side cover portions 24. As shown in Figure 8, the cover 3 is fixed to the shutter box 2 from below with screws 26.

[0012] For comparison, Figures 9 and 10 show the vertical frame 92 of a conventional sash with shutters and the upper part of a conventional sash with shutters. As shown in Figure 9, the vertical frame 92 of the conventional sash with shutters has a hollow portion 96 cut out from the inner periphery only at the upper end portion facing the end face of the top frame 97 (see Figure 10), and the shutter box 90 is attached to the inner side wall 94 of the vertical frame 92. Therefore, as shown in Figure 10, the wiring 91 to the shutter box 90 had to be forcibly bent and processed within the narrow range between the inner side wall 94 and the outer side wall 95 of the vertical frame 92, i.e., within the width of the hollow portion 96 (see Figure 9), so as not to interfere with the cover 93, which made installation difficult. As described above, in this opening device, the wiring 7 to the shutter box 2 protrudes to the side of the outer side wall 5 of the vertical frame 1 at the front part 6 of the shutter box 2, and the protruding wiring 7 is covered from the outer side with a cover 3 (see Figure 4), which makes it easier to handle the wiring 7 to the shutter box 2 and improves workability.

[0013] As shown in Figure 2, guide rails 27 that guide the shutter curtain 17 are attached to the outside of the left and right vertical frames 1, 1. The inside of the left and right vertical frames 1, 1 are covered by a resin vertical frame 28 attached from the inside. The resin vertical frame 28 has an angle 30 that is screwed to a frame 29 as an integral part.

[0014] As shown in Figure 2, the guide rail 27 is made of an extruded aluminum alloy material and is formed in a generally L-shaped bend in plan view, and has a groove-like guide section 10 with an open inner periphery that guides the slats 9 of the shutter curtain 17. Wind-resistant hooks 31 are attached to both the left and right ends of the slats 9, and the guide section 10 has a protrusion 32 formed inside to prevent the slats 9 from coming loose and engage with the wind-resistant hooks 32 when the slats 9 are blown by the wind. The position of the inner peripheral end 33 of the guide portion 10 in the inner / outer peripheral direction is aligned with the position of the inner peripheral end 34 of the vertical frame 1 on the indoor side (see imaginary line 40 in the drawing). The groove bottom 35 of the guide portion 10 is located on the outer peripheral side of the inner peripheral side wall 36 of the vertical frame 1, and is flush with the outer peripheral side wall 5 of the vertical frame 1.

[0015] In this way, in this opening device, the position of the inner peripheral end 33 of the guide portion 10 of the vertical frame 1 in the inner and outer circumferential directions is aligned with the position of the inner peripheral end 34 on the indoor side of the vertical frame 1, so that when the outer shoji screen 13a is opened, the effective opening W is not narrowed by the guide rail 27 of the shutter 8, as shown in Figure 3, and the effective opening W can be made wider. In addition, this opening device reduces the visible dimension A of the vertical frame 1 on the outside of the room, giving it a neater appearance and improving its design, and also increases the width dimension B between the guide rails 27, 27 of the left and right vertical frames 1, 1, improving the view when the shutter 8 is opened. Furthermore, when passing through the edge of the vertical frame 1 to go from inside the room to outside, the guide rail 27 is unlikely to get in the way, making it easy to ensure a line of movement.

[0016] As shown in Figure 2, the vertical frame 1 on the left side as seen from the inside of the room, located at the door end side of the outer shoji screen 13a, has another resin frame 37 attached to the inner periphery of the resin vertical frame 28, and this resin frame 37 fills the space on the inside of the door end stile 38 of the outer shoji screen 13a. The resin frame 37 has multiple hollow sections 39 that serve as thermal insulation spaces. In this way, by attaching the resin frame 37 to the inner periphery of the vertical frame 1 on the indoor side, heat from inside the room is less likely to be transmitted to the aluminum part of the vertical frame 1, thereby improving the heat insulation performance. The door end frames 38 of the inner and outer shoji screens 13a, 13b are formed from aluminum profiles on the outside and plastic profiles on the inside, and the door end frames 38 are positioned further out than a line 40 connecting the inner circumferential edge 33 of the guide portion 10 of the vertical frame 1 and the inner circumferential edge 34 at the inside end of the vertical frame 1, so that the bottom surface 41 of the glass swallowing groove of the door end frame is flush with the line 40. As a result, this opening device effectively suppresses the transfer of heat between the vertical frame 1 and the door stile 38 and through the door stile 38, further improving the insulation performance, and since the door stile 38 is hidden by the resin vertical frame 28 and resin frame 37 when viewed from inside the room, the interior design and visibility are improved.

[0017] As described above, this opening device comprises a vertical frame 1, a shutter box 2, and a cover 3, the vertical frame 1 has a hollow portion 4, and the hollow portion 4 is cut out from the inner periphery at the top of the vertical frame 1, the shutter box 2 is attached to the outer periphery side wall 5 of the vertical frame 1, and has a front portion 6 that protrudes outside the room beyond the vertical frame 1, and the wiring 7 to the shutter box 2 protrudes to the side from the front portion 6 of the shutter box 2 beyond the outer periphery side wall 5 of the vertical frame 1, and the cover 3 covers the front portion 6 of the shutter box 2 from the outer periphery and hides the wiring 7 (see Figure 4), which makes it easy to handle the wiring 7 to the shutter box 2 and improves workability. Also, by attaching the shutter box 2 to the outer periphery side wall 5 of the vertical frame 1, the effective opening W is increased (see Figure 3). The cover 3 has a side portion (side cover portion) 24 that projects outward beyond the outer peripheral side wall 5 of the vertical frame 1, forming a space 25 for passing the wiring 7 (see Figure 4), so that the wiring 7 is stored in the space 25 in the side portion 24 of the cover 3, and the cover 3 can be attached without any problems even if the wiring 7 projects out to the side beyond the outer peripheral side wall 5 of the vertical frame 1.

[0018] This opening device comprises a vertical frame 1, which has guide portions 10 on the outside of the room that guide slats 9 of the shutter 8, and the position of the inner peripheral end 33 of the guide portion 10 in the inner and outer circumferential directions is approximately aligned with the position of the inner peripheral end 34 of the vertical frame 1 on the inside of the room, thereby making it possible to widen the effective opening W (see Figure 3). Also, the visible dimension A on the outside of the vertical frame 1 is reduced, resulting in a neater appearance and improving the design. The vertical frame 1 has a groove bottom 35 of the guide portion 10 located on the outer periphery side of the inner peripheral side wall 36 of the vertical frame 1 (see Figures 2 and 3), which allows the guide portion 10 to be positioned closer to the outer periphery side of the vertical frame 1, further improving the design and making the effective opening W wider. The vertical frame 1 has a groove bottom 35 of the guide portion 10 that is flush with the outer side wall 5 of the vertical frame 1 (see Figures 2 and 3), which further improves the design and maximizes the effective opening W. The vertical frame 1 has a resin frame 37 at its inner peripheral end on the indoor side, and the resin frame 37 has heat insulating spaces 39, 39, . . . (see FIG. 2), thereby improving the heat insulating performance.

[0019] The present invention is not limited to the above-described embodiments. The material and cross-sectional shape of the vertical frame can be changed as appropriate. The position of the inner circumferential edge of the guide portion of the vertical frame in the inner and outer circumferential directions and the position of the inner circumferential edge of the vertical frame on the room side do not necessarily have to be perfectly aligned, and may be slightly misaligned (for example, about 1 to 5 mm). The shutter slats may be made of aluminum. The window is not limited to a sliding window, but can be of various window types. The present invention is not limited to a window with a shutter, and can also be applied to a standalone shutter provided separately from the window. [Explanation of symbols]
