- 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 shoji screen 2 are fixed to the opening of the building.

Prior to construction, the outward-opening window of this embodiment is fitted with an opening restriction component 5 that limits the opening of the screen 2 relative to the frame 1 attached to the opening in the building, thereby improving safety and ease of construction.
The opening restriction part 5 will be described in detail below.

The opening restriction part 5 of the outward-tilting window of this embodiment is, as shown in FIG. 5(a), a string-like member of a predetermined length, with locking ring parts 5b, 5b formed on both ends of a wire part 5a.
As shown in Figures 4 and 5(b), the opening restriction part 5 has its locking ring portions 5b, 5b locked to the support shaft 41a of the vertical member side bracket 41 and the support shaft 42a of the shoji side bracket 42 before the damper is attached, and is attached so as to be freely attached and detached across the vertical member side bracket 41 and the shoji side bracket 42.

The release restriction part 5 can be attached, for example, by passing the locking rings 5b, 5b through the support shaft 41a of the vertical member side bracket 41 and the support shaft 42a of the shoji side bracket 42, and then screwing in a nut n or the like for attaching the damper, but the attachment method is not particularly limited.

- Installation of damper devices and operator devices for outward opening windows -
An example of a procedure for attaching the damper device 4 and the operator device 3 to an outward-tilting window to which the open-restricting part 5 of this embodiment is attached will be described below.

-An example of a procedure-
(1) Removal of the opening restriction part 5 Before construction is completed, as shown in Figure 6 (a), the outward-tilting window has the opening restriction part 5 attached between the left and right vertical members 13, 14 and the left and right vertical frames 23, 23 of the shoji screen 2, and also has the shoji screen fixing brackets 6 attached between the upper frame 11 of the frame body 1 and the upper frame 21 of the shoji screen 2 to fix the shoji screen 2 in the closed position, so that the shoji screen 2 will not open.

Before installing the damper device 4, the user removes the nuts n, n screwed into the vertical member side bracket 41 and the shoji side bracket 42, as shown in Figure 6 (b), and removes the opening restriction parts 5 that were installed across the left and right vertical members 13, 14 and the left and right vertical frames 23, 23 of the shoji 2.

(2) Installation of the damper device The user installs one end side 4a of the damper device 4 by fitting the one end side 4a of the damper device 4 onto the support shaft 41a of the vertical member side bracket 41 of the right vertical member 14 from which the open limiting part 5 has been removed, and screwing in the washer w and the nut n.
Next, as shown in Figures 7 (a) and (b), the user shrinks the damper device 4 and fits the other end 4b onto the support shaft 42a of the shoji side bracket 42 of the right vertical frame 23, and then attaches the damper device 4 by screwing in the washer w and nut n.

The user then installs the damper device 4 between the left vertical member 13 and the left vertical frame 23 in a similar manner, and attaches the left and right damper devices 4, 4 to the outward-tilting window.

(3) Installation of the operator device Once the left and right damper devices 4 have been installed, the user removes the screen fixing brackets 6 using a tool such as a screwdriver to open the screen 2, and then fixes the frame side guide portion 31 and the screen side guide portion 32 of the operator device 3 to the upper frame 11 and upper frame 21, respectively, as shown in Figure 7 (c).
Thereafter, the user loops the wire member 33 of the operator device 3 around the pulleys of the frame side guide section 31 and the screen side guide section 32 and winds it up onto a reel arranged in the operating section 34, thereby completing the installation of the outward-tilting window.

-Other examples of procedures-
(1) Removing the Shoji Fixing Bracket Prior to installing the operator device 3 and the damper device 4, the user removes the Shoji fixing bracket 6 installed between the upper frame 11 and the upper rail 21 of the Shoji 2 using a tool such as a screwdriver, as shown in Figure 8 (a).

(2) Installation of the operator device 3 With an outward-tilting window, the screen 2 can be freely opened to the outside by removing the screen fixing bracket 6, but the opening restriction part 5 is attached across the vertical member side bracket 41 and the screen side bracket 42, so that the screen 2 is kept open at a specified angle.

As shown in FIG. 8(b), the user fixes the frame side guide part 31 and the shoji side guide part 32 of the operator device 3 to the upper frame 11 and upper frame 21 of the open outward-tilting window, respectively, and, as shown in FIG. 9(a), loops the wire member 33 around the pulleys of the frame side guide part 31 and the shoji side guide part 32 and winds it up on a reel located inside the operating unit 34.

(3) Removing the opening restriction part The outward-tilting window can maintain the shoji 2 in the open position by using the operator device 3, and the user removes the nuts n of the vertical member side bracket 41 and the shoji side bracket 42, as shown in Figure 9 (b), and removes the opening restriction part 5 that was attached across the vertical member side bracket 41 and the shoji side bracket 42.

(4) Installation of the damper device The user installs the left and right damper devices 4, 4 between the left and right vertical members 14 from which the open-restricting parts 5 have been removed and the left and right vertical frames 23, 23 of the shoji screen 2, thereby completing the installation of the outward-tilting window.

--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 left and right vertical members 13, 14 of the frame body 1 and the left and right vertical frames 23, 23 of the shoji screen 2, so that a damper device and operator device can be safely attached when installing the outward-opening window in an opening in a building.

The opening restriction component 5 is attached using the vertical member side bracket and the shoji side bracket of the outward-opening window damper device, so that the existing structure can be used as is without modifying the frame 1, shoji 2, and operator device 3, and can be easily used regardless of the dimensions and shape of the outward-opening window.

Furthermore, by attaching the opening restriction part 5 to the outward-opening window before construction and removing the opening restriction part 5 when installing the damper device and operator device, even if the door fixing bracket 6 is inadvertently removed after the outward-opening window is fixed to the opening, the door 2 will not fall off, and the outward-opening window can be constructed safely.

-Other embodiments-
The window to which the open-restricting part 5 is attached may be a window in which the frame is formed by assembling upper and lower frames and left and right vertical frames (vertical members) all around, but it may also be a window in which a damper device is attached between the vertical members that make up a curtain wall or vertical members such as mullions that make up a continuous window and the vertical frame of a shoji screen, and there is no particular limitation on the vertical members to which the damper device is attached.

In addition, the configuration of the locking parts formed on both ends of the opening restriction part 5 is not limited to the locking ring parts 5b, 5b, and is not particularly limited as long as the opening restriction part 5 can be attached detachably to the vertical member side bracket 41 and the shoji side bracket 42.

Furthermore, 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 member having sufficient strength.
In addition, the configurations of the operator device 3 and damper device 4 of the outward-tilting window are not particularly limited.

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