  The known polygonal window forms a polygonal window frame by connecting ends of a plurality of frame members provided along each side of the window via corner parts. Each frame member is formed by connecting the outdoor frame member and the indoor frame member with screws.

  As described above, since the conventional technology is configured by connecting a plurality of frame members with screws and connecting them via corner parts, the number of connecting portions is large, and the watertight performance of each connecting portion is not high. The watertight performance of the entire polygonal window was not high, and the finish and appearance of the connection were not clean. Furthermore, since the number of constituent members is large, it takes time and cost to assemble and manufacture. In addition, in the conventional polygonal window, it has been unavoidable that the outer wall of the building is soiled by rain water or condensed water dripping from the window.

The present invention has been made in view of the above points, and the first problem is that the number of constituent members is reduced as much as possible, the watertightness is improved, the appearance is excellent, and the labor and cost for production are low. It is to provide a polygonal window that does not take up.
A second problem is to provide a polygonal window that prevents the outer wall of the building from being soiled by dripping rainwater or condensed water.

  In order to solve the above first problem, the present invention mainly comprises a metal window frame, and a panel is fixed in the window frame, or a shoji is attached to the window frame so as to be opened and closed. In the window, the metal window frame is integrally formed of an aluminum casting (claim 1).

  It is desirable that the draining protrusion is formed by extending the bent wall downward from the outer peripheral wall.

  It is preferable that a screw receiving portion for screwing a screw for fixing a resin frame attached in the metal window frame is integrally provided at a connection portion between the outer peripheral wall and the outward flange.

  According to the invention of claim 1, since the metal window frame is integrally formed of an aluminum casting, unlike the prior art having a connection portion by a corner part of a plurality of frame members, there is no connection portion, so that it is highly watertight. Performance is obtained. In addition, since the number of constituent members is small, there is no need for assembling labor and costs.

  According to invention of Claim 2, the water collection cavity part which collects the rain water which flows down the panel outer surface of a panel or a shoji, and / or the dew condensation water which flows down the indoor side surface of the said panel or shoji is formed in the lower part of a metal window frame. Since a drain hole for draining downward is formed at the bottom of the water collection cavity, even if rainwater or dew condensation enters from the seal part of the panel or shoji Since water collects in the water collecting cavity and drains from the drain hole, it is prevented from leaking into the room.

  According to invention of Claim 3, since the draining protrusion is provided in the outdoor side vicinity of the drain hole, it prevents that the water drained from a drain hole pollutes the building outer wall under a polygonal window. Is done.

It protrudes 15p slightly outward from the outer end. As a result, the rainwater that falls down and flows down to the upper inclined portion 11US on both sides of the top portion 11t of the outer peripheral wall 11 and the outward flange 12 existing on the indoor side of the upper inclined portion stops at the water return protrusion 15. The water is discharged, guided from the outdoor projecting portion 15p in the outdoor direction, and discharged. Of the outer peripheral wall 11, at least a portion inclined to both sides from the top 11 t is formed to be thin so as to be inclined inward in the outdoor direction. Thereby, the rainwater flowing down along the upper inclined portion 11US flows toward the outdoor projecting portion of the water return projection 15 and is guided and drained from the water return projection 15 to the outdoor direction. It is like that.

  The inward flange 13 is not connected to the bottom 11b and its vicinity immediately below the top 11t of the outer peripheral wall 11, but a triangular hole 13h is formed between the bottom 11b and its vicinity.
