FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] As an embodiment of the opening device, we will explain the example of a double-glazed window having an outer window A with a frame and frame made of metal such as aluminum alloy, and an inner window B with a frame and frame made of resin, with reference to the drawings.

[0010] (Double window configuration) The exterior window A, located on the outside of a building opening, is constructed as shown in Figures 1 and 2, with inner and outer shoji screens 20, 30 supported on the inner periphery of a frame body 10 consisting of an upper frame 11, a lower frame 12, and left and right vertical frames 13, 14 assembled around it, so that they can be opened and closed freely.

[0011] The inner and outer shoji screens 20, 30 of the outer window A are formed by fitting panel bodies 25, 35 of glass or the like into a frame body consisting of an upper frame 21, 31, a lower frame 22, 32, a door joint frame 23, 34 and a door end frame 24, 33, respectively.

[0012] When the outer window A is closed, the inner and outer shoji screens 20, 30 of the outer window A are locked by a crescent lock (not shown) or the like, at the door frame 23 of the inner shoji screen 20 and the door frame 34 of the outer shoji screen 30, and the door end frames 24, 33 of each screen abut against the right and left vertical frames 14, 13, and are pulled toward the interior of the room and supported.

[0013] The joint frame 34 of the outer shoji screen 30 has a hollow portion 34a formed on the exterior side, and the joint frame 23 of the inner shoji screen 20 has a hollow portion 23a formed on the interior side, improving the strength of the joint portion of the outer shoji screen 30.

[0014] The inner window B, located on the indoor side of the building opening, is constructed by inner and outer shoji screens 50, 60 that are supported on the inner periphery of a frame body 40, which is made up of an upper frame 41, a lower frame 42, and left and right vertical frames 43, 44 assembled around it, as shown in Figures 1 and 2, and can be opened and closed freely.

[0015] The inner and outer shoji screens 50, 60 of the inner window B are formed by fitting panels 55, 65 such as double-glazed glass into a frame body consisting of an upper frame 51, 61, a lower frame 52, 62, a door frame 53, 64 and a door end frame 54, 63.

[0016] When the inner window B is closed, the inner and outer shoji screens 50, 60 of the inner window B are airtight with their respective door frames 54, 63 abutting against the right and left vertical frames 44, 43, and the door frame 53 of the inner shoji screen 50 and the door frame 64 of the outer shoji screen 60 are airtight at the smoke-proof portion.

[0017] As described above, the double-glazed window of this embodiment has an inner window B made of resin installed on the indoor side of the outer window A, creating a space between the outer window A and the inner window B, thereby improving the insulation of the building opening. In double-glazed windows, the resin inner window B has lower pressure resistance than the outer window A, and when strong winds such as a typhoon suddenly apply pressure when the front door or a window facing the outside is opened, there is a possibility that the inner window B will warp, come off, or break, as shown in Figure 4.

[0018] The opening device (double window) of this embodiment has the pressure on the inner window B borne by the strong outer window A, thereby suppressing warping of the inner window B and preventing it from coming off or breaking. Specifically, as shown in Figures 1 and 2, the opening device (double window) of this embodiment has a negative pressure receiver 8 on the outdoor side of the joint frame (vertical member) 64 of the outer shoji screen 60 of the inner window B, and when the inner window B warps to the outdoor side, it abuts against the indoor side of the joint frame (vertical member) 23 of the inner shoji screen 20 of the outer window A, thereby suppressing the warping of the inner window B and preventing damage or detachment.

[0019] The negative pressure receiver 8 in this embodiment is made of, for example, a resin material and is constructed from a cubic-shaped block of material, and is attached to the outdoor surface of the joint frame (vertical member) 64 of the outer screen 60 of the inner window B at approximately the center in the vertical direction. The negative pressure receiver 8 may be attached to the exterior side of the vertical member 64 using, for example, double-sided tape, but it may also be attached using screws, etc., and the method of attachment to the vertical member is not limited.

[0020] The dimensions of the negative pressure receiver 8 attached to the outer screen 60 of the inner window B preferably have a visible width dimension slightly smaller than the visible width dimension of the door frame 64 of the outer screen 60, and also preferably have a visible dimension such that when attached to the exterior side of the door frame 64 of the outer screen 60, only clearance C is left between it and the interior side of the door frame 23 of the inner screen 20 of the outer window A for opening and closing the inner window B and the outer window A.

[0021] When sudden pressure is applied to a double-glazed window equipped with a negative pressure receiver 8, the negative pressure receiver 8 provided on the door frame 64 of the outer screen 60 of the inner window B, which tends to bend toward the outside of the room, comes into contact with the indoor side of the door frame 23 of the inner screen 20 of the outer window A, as shown in Figure 3.

[0022] (Effects of the opening device of this embodiment) As described above, the opening device of this embodiment has a negative pressure receiver 8 on the outdoor side of the joint frame (vertical member) 64 of the outer screen 60 of the inner window B, so that even if pressure is applied to the inner window B and it warps to the outdoor side, the negative pressure receiver 8 abuts against the indoor side of the joint frame 23 of the inner screen 20 of the outer window A, which has high wind pressure resistance, thereby restricting further warping of the inner and outer screens 50, 60 of the inner window B and preventing the inner window B from coming off or being destroyed.

[0023] Furthermore, in the opening device of this embodiment, the negative pressure receiver 8 is made of a resin material, which prevents scratches and other damage from occurring when the negative pressure receiver 8 comes into contact with the door frame 23 of the inner shoji screen 20 of the outer window A, and also reduces collision noise and other issues.

[0024] -Variations- In the opening device of this embodiment, the negative pressure receiver 8 is attached to the exterior side (one side) of the door frame 64 of the exterior screen 60 of the interior window B, so that when the interior window B warps when negative pressure is generated, the negative pressure receiver 8 abuts against the interior side (the other side) of the door frame 23 of the interior screen 20 of the exterior window A. However, the negative pressure receiver 8 may also be attached to the door frame 23 (one side) of the interior screen 20 of the exterior window A, so that when the interior window B warps when negative pressure is generated, the negative pressure receiver 8 abuts against the door frame 64 (the other side) of the exterior screen 60 of the interior window B. Furthermore, the installation position of the negative pressure receiver 8 attached to the door frame 64 of the outer screen 60 of the inner window B or the door frame 23 of the inner screen 20 of the outer window A is not limited to the central position in the vertical direction, and the number of attachments is also not limited.

[0025] The inner window B that constitutes the double-glazed window may be retrofitted to the interior side of an existing outer window A, or the outer window A and the inner window B may be installed at the same time. Furthermore, both the outer window A and the inner window B are not limited to double-panel sliding windows, but may be four-panel sliding windows or windows that include a fixed window in part, as long as the left-right position of the vertical member of the inner window B (or the vertical member of the outer window A) to which the negative pressure receiver 8 is attached matches the left-right position of the vertical member of the outer window A (or the vertical member of the inner window B).

[0026] It goes without saying that the above embodiments do not limit the invention described in the claims, but are to be treated as examples. [Explanation of symbols]
