-Operator device-
The operator device 3 of this embodiment is a four-point pulley type operator device having two frame side guide parts 31 and two shoji side guide parts 32.

As shown in Figures 3(b) and (c), the frame side guide portion 31 has a plate-shaped mounting portion 31a fixed to the underside of the projection wall 11a of the upper frame 11, a pair of support wall portions 31b, 31b having a guide hole 31c that rises from one surface of the mounting portion 31a (the underside when attached to the upper frame 11) and penetrates in the projection direction, a pulley holding arm 31d supported between the support wall portions 31b, 31b so as to be freely rotatable, and a pulley 31e supported so as to be freely rotatable on the pulley holding arm 31d.
Similar to the frame side guide part 31 shown in Figures 3 (b) and (c), the shoji side guide part 32 has an attachment part 32a, a support wall part 32b having a guide hole 32c, a pulley holding arm 32d, and a pulley 32e.

As shown in FIG. 4, the operator device 3 has a pair of frame side guide parts 31, 31 fixed to the underside of the projected wall 11a of the upper frame 11 with a predetermined distance between them, and a pair of shoji side guide parts 32, 32 fixed to the upper surface of the interior projected wall 21c of the upper frame 21 with a distance shorter than the distance between the frame side guide parts 31, 31 fixed to the upper frame 11, and a wire member 33 is hung around the frame side guide parts 31 and the shoji side guide parts 32.

The wire member 33 is formed by fixing a crimped portion 33b to one end of the wire body 33a (the left end as viewed from the inside of the room in FIG. 4), and the wire body 33a is passed through a guide hole 31c in one support wall portion 31b of one frame side guide portion 31, and the crimped portion 33b is engaged with the support wall portion 31b.

The wire body 33a of the wire member 33, one end of which is secured to the support wall portion 31b by the crimp portion 33b, is routed around the pulley 31e of the frame side guide portion 31 on one side, the pulley 32e and support wall portion 32b of the shoji side guide portion 32 on one side, the support wall portion 32b and pulley 32e of the shoji side guide portion 32 on the other side, and the pulley 31e and support wall portion 31b of the frame side guide portion 31 on the other side, and is guided to the outer member 35.

As shown in Figures 3(a) and 4, the end of the outer member 35 of the operator device 3 on the outward tilting window side is fixed to the upper frame 11 by a cable stopper 35a or the like, and passes through a through hole 11f formed in the interior facing wall 11b of the upper frame 11 to reach the operating unit 34, and the other end of the wire member 33 guided to the outer member 35 is wound up on a reel arranged inside the operating unit 34.

When the user operates the operating unit 34 to unwind the wire member 33 from the reel, the upper frame 21 of the screen 2 is allowed to move away from the upper frame 11 as shown in Figures 4 and 5, and the screen 2 can be opened by the biasing force of the damper device 4.

- Opening restriction parts -
The above-mentioned outward-opening windows are equipped with an operator device 3 and a damper device 4 for opening and closing the shoji screen 2, and during construction, the operator device 3 and damper device 4 may be attached after the frame 1 and the shoji screen 2 are fixed to the building opening.
In such cases, since the shoji screen 2 of an outward-tilting window opens to the outside of the room, installation of the damper device 4 is complicated, as it requires the use of a holder with a suction cup that adheres to the glass in order to mount the damper device 4 between the vertical frame 13 of the frame body 1 and the vertical stile 23 of the shoji screen 2, thereby supporting the shoji screen 2 in the open position.

The outward-opening window of this embodiment is equipped with an opening restriction component that limits the opening of the shoji screen 2 relative to the frame 1 attached to the building opening, so that the shoji screen 2 can be supported in the open position without the use of special retaining devices, etc., and the damper device 4 can be easily installed.
The opening restriction part will be described in detail below.

The opening restriction part 5 of the outward-tilting window of this embodiment is formed by fixing crimped portions 5b, 5b to both ends of a wire portion (string-like portion) 5a of a predetermined length, as shown in Figure 6 (a).
As shown in Figures 6 (b) and (c), the open-restricting part 5 is attached with the wire portion 5a routed around the pulley 31e of the frame side guide portion 31 and the pulley 32e of the shoji side guide portion 32, and both ends of the wire portion 5a guided through the guide hole 31c of the support wall portion 31b of the frame side guide portion 31 and the guide hole 32c of the support wall portion 32b of the shoji side guide portion 32.
In Figure 6 (b), the frame side guide portion 31 and the shoji side guide portion 32 are shown slightly spaced apart in the indoor/outdoor direction to make it easier to understand the state in which the opening restriction part 5 is guided. However, as shown in Figure 3 (a), the frame side guide portion 31 and the shoji side guide portion 32 of an outward-tilting window may be closer together.

The opening restriction part 5 can be attached, for example, by passing the wire part 5a, which has the crimped part 5b fixed to one end, through the guide hole 31c of the frame side guide part 31, the pulley 31e, the pulley 32e of the shoji side guide part 32, and the guide hole 32c, and then fixing the crimped part 5b to the other end, but the method of attaching the opening restriction part 5 is not limited.

After passing through the guide hole 32c of the shoji-side guide part 32, the wire part 5a on the other end extending from the guide hole 32c may be placed in the space partitioned by the airtight material s11 and the airtight material s12, or it may be exposed to the inside or outside of the shoji 2 by utilizing the elasticity of the airtight material s11 or the airtight material s12 and fixed to an appropriate position on the upper frame 11 or the upper frame 21 with tape or the like.

As shown in Figure 6(c), when the shoji screen 2 is opened, an outward-tilting window with an opening restriction part 5 attached between the frame-side guide part 31 and the shoji-side guide part 32 is supported in an open state with an opening angle determined by the length of the wire part 5a, as the crimped parts 5b fixed to both ends of the wire part 5a are engaged with the support wall parts 31b of the frame-side guide part 31 and the support wall parts 32b of the shoji-side guide part 32.

- Installation of damper devices for outward opening windows -
The procedure for attaching the damper device 4 to an outward-tilting window to which the open-restricting part 5 of this embodiment is attached will be described below.

(Removing the fixing bracket)
Before construction, the outward-opening window is fitted with a fixing bracket 6 that secures the upper frame 21 of the screen 2 to the upper frame 11 of the frame body 1, thereby preventing the screen 2 from opening. Prior to installing the damper device 4, the user uses a tool such as a screwdriver to remove the fixing bracket 6 that is attached to the outward-opening window that is fixed to the building opening, as shown in Figure 8(a).

As shown in FIG. 7( b ), the fixing bracket 6 of this embodiment has a frame side member 61 and a screen side member 62 .
The frame side member 61 has a facing portion 61a that is engaged with the indoor side surface of the indoor side facing wall 11b of the upper frame 11, a projection portion 61b that extends along the lower surface of the indoor side facing wall 11b continuing from the lower end of the facing portion 61a, and a connecting portion 61c that extends and bends downward continuing from the outdoor side end of the projection portion 61b.

The shoji side member 62 has a visible portion 62a that runs along the indoor side surface of the indoor side wall 21b of the upper frame 21, a projection portion 62b that extends continuous with the lower end of the visible portion 62a along the upper surface of the indoor side projection wall 21c of the upper frame 21, and a connecting portion 62c that bends downward and extends continuous with the indoor side end of the projection portion 61b.
In addition, the frame side member 61 and the shoji side member 62 may have protective materials c such as cushioning material attached to the contact portion between the upper frame 11 and the upper stile 21.

As shown in Figures 7(a) and (c), for example, the shoji side member 62 is attached by inserting the facing portion 62a and the facing portion 62b through the gap 32f between the mounting portion 32a of the shoji side guide portion 32 and the pulley retaining arm 32d so that the facing portion 62a engages with the exterior portion of the shoji side guide portion 32 fixed to the interior facing wall 21c of the upper frame 21 of the shoji 2, and the connecting portion 62c is positioned so that it extends downward along the interior side of the interior wall 21b.

The shoji side member 62 arranged on the upper frame 21 cannot be pulled out even if it is pulled horizontally toward the room, as the facing part 62a is engaged with the outside part of the shoji side guide part 32. However, it can be removed by pulling the connecting part 62c toward the room so that it moves upward.

The frame side member 61 abuts the exterior side of the facing portion 61a against the interior side of the interior facing wall 11b of the upper frame 11, and the connecting portion 61c is fixed to the connecting portion 62c of the shoji side member 62 arranged on the upper frame 21 by a screw b or the like, thereby preventing the shoji 2 from being opened.
The configuration of the fixing bracket 6 is not limited in any way.

(Installation of damper device)
By removing the fixing bracket 6 attached to the outward-tilting window, the shoji screen 2 can be freely opened to the outside of the room, but as shown in Figure 8 (b), an opening restriction part 5 is attached across the frame side guide part 31 of the upper frame 11 and the shoji side guide part 32 of the upper frame 21, so the shoji screen 2 is kept open at a specified angle.

The user can attach one end of the damper device 4 by fitting the end portion 4a of one end of the damper device 4 into the rotating shaft 41a of the frame side bracket 41 of the vertical frame 13 on one side (the right side) that is exposed when the shoji screen 2 is in the open state, and then screwing in the washer w and nut n.
Next, while shrinking the damper device 4, the other end 4b is fitted onto the rotating shaft 42b of the shoji side bracket 42 of one (right) vertical frame 23, and then the damper device 4 can be installed by screwing in the washer w and nut n.

As shown in FIG. 9(a), the left and right damper devices 4, 4 can be attached to an outward-tilting window by attaching the damper device 4 between the other (left) vertical frame 13 and vertical sill 23 in a similar manner.

(Removing the opening restriction parts)
Once the damper device 4 has been installed between the left and right frames 13, 13 and the left and right vertical frames 23, 23 of the shoji screen 2, the user cuts the wire portion (string-like portion) 5a of the open-restricting part 5 with a tool such as pliers, and tilts the open-restricting part 5 outward to remove it from the window, as shown in Figure 9 (b).
Thereafter, the wire member 33 of the operator device 3 is looped around the pulleys of the frame side guide section 31 and the screen side guide section 32 and wound up onto a reel arranged in the operating section 34, completing the installation of the outward-tilting window.
The above-described installation work for the damper device for an outward-opening window is merely an example, and the installation method is not limited thereto.

--Effects of the outward-tilting window of this embodiment--
As described above, in the outward-opening window of this embodiment, the opening restriction part 5 is attached between the upper frame 11 of the frame body 1 and the upper frame 21 of the screen 2, so that when attaching a damper device to an outward-opening window installed in an opening in a building, the screen 2 can be held in the open position without using any special holding tools, etc., and the damper device can be easily attached.

The opening restriction component 5 is attached using the frame side guide part 31 and the screen side guide part 32 that guide the wire member 33 of the outward-tilting window operator device 3, so that the existing structure can be used as is to prevent the screen from falling down without changing the frame body 1, screen 2, and operator device 3, and it can be easily used regardless of the dimensions and shape of the outward-tilting window.

-Other embodiments-
The operator device 3 for the outward-opening window is not limited to a four-point pulley type, but may be a three-point pulley type operator device.
In this case, the opening restriction part 5 may be attached between the frame side guide part 31 and the shoji side guide part 32 by engaging the crimped portion 5b at one end of the wire member 33 with the support wall portion 31b of the frame side guide part 31, wrapping the wire portion 5a around the pulley 32e of the shoji side guide part 32, and then passing the crimped portion 5b on the other side through the support wall portion 31b of the other frame side guide part 31, as shown in Figures 10 (a) and (b).

Even if the opening restriction component 5 is a three-point pulley type, the wire member 33 may be attached between one of the frame side guide parts 31 and the shoji side guide part 32, as in the case of the four-point pulley type operator device 3.

Furthermore, the connection between the opening restriction part 5 and the frame side guide portion 31 and the shoji side guide portion 32 is not limited to engaging the crimp portion 5b with the support wall portions 31b, 32b.
For example, as shown in Figures 11 (a) and (b), the crimped portion 5b of the opening restriction part 5 may engage with any part of the frame side guide part 31 and the shoji side guide part 32, such as engaging with the pulleys 31e, 32e of the frame side guide part 31 and the shoji side guide part 32 and the pulley holding arms 31d, 32d that hold the pulleys 31e, 32e.
In addition, Figures 11 (a) and (b) show an example of a frame side guide portion 31 and a shoji side guide portion 32 in which the support wall portions 31b, 32b do not have guide holes 31c, 32c, but even if the frame side guide portion 31 and the shoji side guide portion 32 in which the support wall portions 31b, 32b have guide holes 31c, 32c, the crimping portion 5b of the opening restriction part 5 may engage with any portion of the frame side guide portion 31 and the shoji side guide portion 32.

The wire portion 5a of the opening restriction part 5 is not limited to a metal wire, and is not particularly limited as long as it is a string-like material with sufficient strength.

The opening degree of the shoji screen 2 regulated by the opening regulation part 5 is not limited in any way, and may be an opening degree that allows the shoji screen side end 4b to be attached to the rotation axis 42a of the shoji screen side bracket 42 without shortening the damper device 4.

It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples.
