[0012] - Window connection by the mullion - The mullion 1 of the continuous window of this embodiment is a long member made of a metal such as an aluminum alloy. As shown in FIGS. 2(a) and 6(a), a main body portion 1a in which a looking-in wall extends from the outdoor side surface of a rectangular hollow portion 1b, an outdoor side wall 1c that is continuous with the outdoor side of the main body portion 1a and extends in the left and right finding directions, tight material holding portions 1d, 1d provided on the left and right looking-in surfaces of the hollow portion 1b, and a tapping hole 1e provided at a position between the left and right tight material holding portions 1d, 1d in the hollow portion 1b, more specifically, at a position generally on the line connecting both tight materials s1, s1 (airtight lines). The tight materials s1, s1 are attached to the left and right tight material holding portions 1d, 1d.

[0013] Engagement portions 1f, 1f are formed on the indoor side surface of the hollow portion 1b for the indoor sides of the left and right vertical frames 23, 34 to engage, and engagement portions 1g, 1g are formed on the indoor side of the outdoor side wall 1c for the outdoor sides of the left and right vertical frames 23, 34 to engage.

[0014] As shown in FIGS. 2(a) and 6(a), the vertical frames 23 and 34 of the FIX windows 2 and 3 of the continuous window of the present embodiment have prospective walls 23a and 34a, indoor side walls 23b and 34b extending in the outer peripheral direction from the indoor side ends of the prospective walls 23a and 34a, and outdoor side walls 23c and 34c extending in the outer peripheral direction from the outdoor side ends of the prospective walls 23a and 34a. The vertical frames 23 and 34 are provided with glass width walls 23d and 34d and edge locking portions 23e and 34e for fitting a panel body into the inner peripheral surfaces of the prospective walls 23a and 34a, and the tips of the indoor side walls 23b and 34b are bent outward to form locking portions 23f and 34f.

[0015] The indoor side walls 23b and 34b of the vertical frames 23 and 34 extend above the prospective walls 23a and 34a and the outdoor side walls 23c and 34c to be provided with extending portions 23g and 34g, and the glass width walls 23d and 34d and the edge locking portions 23e and 34e provided on the inner peripheral surfaces of the prospective walls 23a and 34a of the vertical frames 23 and 34 are cut out over a predetermined range from the upper ends of the prospective walls 23a and 34a to form contact surfaces 34h (the contact surface of the vertical frame 23 is not shown) with which the end surfaces of the upper frames 21 and 31 of the FIX windows 2 and 3 abut.

[0016] As shown in FIGS. 2(a) and 5(a), the upper frames 21 and 31 of the FIX windows 2 and 3 of the continuous window of the present embodiment have main body portions 21a and 31a having a hollow cross-sectional shape with a glass width on the indoor side inner peripheral surface, and indoor side walls 21b and 31b where the indoor side ends of the main body portions 21a and 31a rise in the outer peripheral direction, and have tapping holes 21c and 31c for connecting to the vertical frames 23 and 34 inside the hollows of the main body portions 21a and 31a.

[0017] In addition, as shown in FIG. 5(c), the upper frames 21 and 31 of the present embodiment are formed such that the indoor side walls 21b and 31b rising from the indoor side ends of the main body portions 21a and 31a are bent in a crank shape at a predetermined position from the lower ends, and the upper portions of the indoor side walls 21b and 31b are shifted inward by a distance d with respect to the lower portions.

[0018] For the upper frames 21 and 31 and the vertical frames 23 and 34 of the FIX windows 2 and 3, as shown in Fig. 2(b), the end faces of the upper frames 21 and 31 are abutted against the abutting surface 34h (the abutting surface of the vertical frame 23 is not shown) formed on the inner peripheral surface of the prospective walls 23a and 34a of the vertical frames 23 and 34, and are fixed and connected by screws b3 from the outer peripheral side.

[0019] As shown in Fig. 6(a), the vertical frames 23 and 34 to which the upper frames 21 and 31 are connected have locking portions 23f and 34f on the indoor side walls 23b and 34b engaged with the engaging portions 1f and 1f provided on the indoor side surface of the hollow portion of the upright 1, and the tips of the outdoor side walls 23c and 34c are engaged with the engaging portions 1g and 1g formed on the indoor side of the outdoor side wall 1c of the upright 1, and are arranged on the left and right of the upright 1.

[0020] For the continuous window with the vertical frames 23 and 34 arranged on the left and right of the upright 1, the tight materials s1 and s1 held by the tight material holding portions 1d and 1d of the upright 1 abut against the outdoor side surfaces of the indoor side walls 23b and 34b of the vertical frames 23 and 34, and an airtight line is formed to make the space between the upright 1 and the vertical frames 23 and 34 airtight.

[0021] As shown in Figs. 3(a) and (b), a cover member 5 is arranged at the upper part of the upright 1 with the vertical frames 23 and 34 arranged on the left and right. The cover member 5 is fixed to the upright 1 by screws b1 and is also fixed to the left and right FIX windows or the building body by screws b2 and b2, covering the upper surfaces of the upright 1 and the vertical frames 23 and 34 arranged on the left and right of the upright 1.

[0022] -Cover member- For the continuous window of this embodiment, a sealing material is arranged on the lower surface of the cover member 5. By fixing the cover member 5 to the upper part of the upright 1, the upper parts of the upright 1 and the left and right vertical frames 23 and 34 can be sealed. Hereinafter, the cover member 5 will be further described with reference to the drawings.

[0023] As shown in Fig. 4, the cover member 5 of the continuous window of this embodiment has a horizontal portion 5a covering the upper surfaces of the upright 1 and the vertical frames 23 and 34, a rising wall portion 5b rising continuously on the indoor side of the horizontal portion 5a, and a drainage portion 5c extending downward continuously on the outdoor side of the horizontal portion 5a.

[0024] The cover member 5 is formed with screw holes 5d for fixing to the upright 1 at the central position in the finding direction near the indoor side of the horizontal portion 5a, and screw holes 5e, 5e are formed at positions spaced apart in the finding direction near the upper side of the rising wall portion 5b. Note that the rising wall portion 5b of the cover member 5 is formed by being bent in a crank shape at a predetermined position from the lower end so as to shift the position in the prospective direction, similar to the indoor side walls 21b, 31b of the upper frames 21, 31. Further, the rising wall portion 5b of the cover member 5 is inclined toward the indoor side as a whole.

[0025] Sealing materials that contact the upright 1 or the vertical frames 23, 34 are arranged on the lower surface of the horizontal portion 5a and the indoor side surface of the rising wall portion 5b of the cover member 5. Specifically, for the cover member 5, a first sealing material 61 is arranged continuously from the lower surface near the indoor side at the center in the finding direction of the horizontal portion 5a to the indoor side surface of the central portion in the finding direction of the rising wall portion 5b, and second sealing materials 62, 62 are arranged continuously from the lower surfaces of the left and right end portions in the finding direction of the horizontal portion 5a to the indoor side surfaces of the left and right end portions in the finding direction of the rising wall portion 5b, and a third sealing material 63 is arranged between the left and right second sealing materials 62, 62 on the outdoor side lower surface of the horizontal portion 5a.

[0026] The cover member 5 with the sealing materials arranged on the lower surface of the horizontal portion 5a and the indoor side surface of the rising wall portion 5b is arranged to cover the upper surface of the upright 1 from above the upright 1 with windows arranged on the left and right as shown in Fig. 5(a), and then, as shown in Figs. 5(b) and 6(b), it is fixed to the upper part of the upright 1 by screwing the screw b1 from the screw hole 5d of the cover member 5 into the tapping hole 1e of the upright 1. Note that in the continuous window of the present embodiment, the cover member 5 is further screwed to the upper frames 21, 31 or the housing with the screw b2 from the screw hole 5e of the rising wall portion 5b.

[0027] By fixing the cover member 5 to the upper part of the upright 1, the second sealing material 62 provided on the cover member 5 is pressed against the upper surfaces of the main body portions 21a, 31a of the upper frames 21, 31 of the left and right windows and the indoor side walls 21b, 31b as shown in FIGS. 5(b) and 6(b), suppressing the intrusion of rainwater and the like transmitted from the upper frames 21, 31 from the left and right sides of the upright 1.

[0028] The third sealing material 63 provided on the cover member 5 is pressed against the outdoor side upper surfaces of the main body portions 21a, 31a of the upper frames 21, 31 of the left and right windows, the outdoor side walls 23c, 34c of the left and right vertical frames 23, 34, and the upper surface of the outdoor side wall 1c of the upright 1, suppressing the blowing-in and intrusion of rainwater and the like from the outdoor side of the upright 1.

[0029] The first sealing material 61 provided on the cover member 5 is such that the portion 61a provided on the lower surface of the horizontal portion 5a of the cover member 5 is pressed against the left and right tight materials s1, s1 arranged on the left and right sides of the upright 1, the left and right vertical frames 23, 34, and the hollow portion 1b of the upright 1, thus continuous the airtight line formed by the left and right tight materials s1, s1 and suppressing the intrusion of water from between the vertical frames 23, 34 and the upright 1. Further, the first sealing material 61 is such that the portion 61b provided on the indoor side of the rising wall portion 5b of the cover member 5 is pressed between the extended portions of the indoor side walls 23b, 34b of the left and right vertical frames 23, 34 (see FIG. 3(a)), thus making the space between the indoor side walls 23b, 34b airtight.

[0030] -Effect of the outward-opening window of this embodiment- As described above, in the continuous window of this embodiment, since the cover member 5 with a sealing material arranged on its lower surface is fixed to the upper part of the upright 1, it is possible to easily make the upper part of the upright 1 airtight. In particular, on the lower surface of the cover member 5, the first sealing material 61 is arranged to contact the tight materials s1, s1 that make the space between the upright 1 and the left and right vertical frames 23, 34 airtight and to connect both tight materials s1, s1. Therefore, by fixing the cover member 5, it is possible to make the airtight line continuous with the vertical frames formed on the left and right sides of the upright 1.

[0031] Moreover, in the casement window of this embodiment, a tapping hole 1e for fixing the cover member 5 to the mullion 1 is formed at a position between both tight members s1, s1 (left and right airtight lines), or more specifically, at a position generally on the line connecting both tight members s1, s1. Therefore, by tightening the screw b1 for fixing the cover member 5 into the tapping hole 1e, the first sealing material 61 close to the tapping hole 1e can be surely pressed against both tight members s1, s1.

[0032] Note that since the tight member formed of a resin material or the like may shrink due to deformation over time or the like, the first sealing material 61 pressed against the left and right tight members s1, s1 is preferably formed thicker than the second sealing material 62 or the third sealing material 63 that abuts against the upper frame 21, 31 or the vertical frame 23, 34 so as to be sufficiently pressed against the tight members s1, s1.

[0033] Furthermore, since the rising wall portion 5b of the cover member 5 is entirely inclined toward the indoor side, by fixing the cover member 5 to the upper part of the mullion 1, the first sealing material 61 and the second sealing material 62 disposed on the indoor side surface of the rising wall portion 5b are naturally pressed against the indoor side wall portions of the upper frame 21, 31 and the vertical frame 23, 34, and stable airtightness can be obtained.

[0034] Note that the indoor side walls 21b, 31b of the upper frame 21, 31 and the rising wall portion 5b of the cover member 5 in this embodiment are formed to be bent in a crank shape at a predetermined position from the lower end to shift the prospective direction position. Therefore, a space for accommodating the screw head when the indoor side walls 21b, 31b of the upper frame 21, 31 and the rising wall portion 5b of the cover member 5 are fixed to the anchor member A or the like with screws b2 is formed, and the outer wall or the like constructed on the outdoor side of the indoor side walls 21b, 31b can be arranged smoothly.

[0035] -Other Embodiments- The casement window is not limited to an externally attached window, and may be a casement window in which semi-externally attached windows are arranged on the left and right. In the case of a multi-panel window with semi-exterior-mounted windows, as shown in Fig. 9(a), the gasket holders 1d, 1d provided on the prospective surfaces on the left and right of the hollow portion 1b of the mullion 1 are provided closer to the outdoor side of the hollow portion 1b, and tapping holes 1e are formed at positions on the same wall as the walls constituting the gasket holders 1d, 1d and generally on the line connecting both gaskets s1, s1. Then, the gaskets s1, s1 held by the gasket holders 1d, 1d abut against the outdoor side surfaces of the abutting pieces 23i, 34i extending in the outer peripheral direction from the outer peripheral surfaces of the vertical frames 23, 34, thereby forming an airtight line that airtightens the space between the mullion 1 and the vertical frames 23, 34.

[0036] Even in the case of a multi-panel window with semi-exterior-mounted windows arranged left and right, as shown in Fig. 7, the configuration of the cover member 5 is basically the same although the dimensions in the prospective direction are different. As shown in Figs. 8 and 9, by fixing it above the mullion 1, the upper portions of the mullion 1 and the left and right vertical frames 23, 34 can be sealed.

[0037] Note that the screws for fixing the cover member 5 to the mullion 1 and the vertical frames 23, 34, etc. only need to have at least the screw b1 for fixing to the tapping hole 1e of the mullion 1, and the screw b2 for fixing the rising wall portion 5b of the cover member 5 may not be necessary. Conversely, other screws for fixing the cover member 5 may exist.

[0038] Note that the shape of the mullion is not limited in any way, and it may be a mullion without a hollow portion. Also, the windows arranged on the left and right of the mullion are not limited to FIX windows, and there is no particular limitation on the window type. The above embodiments do not limit the invention described in the claims and are, of course, treated as examples.
