Description

[Detailed description of the invention] (Industrial field of application, target) This invention is a bay window that is formed by projecting outward from a window mounting opening in a building, and in particular, a bay window in which the projecting front surface or the entire projecting area is curved in an arc shape. Regarding the bow-shaped bay window.

(Conventional Example) A bay window that is formed to extend outward from a window mounting opening of a building will be described with reference to the embodiment drawings of this invention. As shown in FIGS. 1 to 3, a roof frame 1, It consists of a window sill frame 2, window frames 3 and 4, a top plate 5 (see FIG. 4), and a base plate 6 (numerals are the same as those for explaining the embodiments of this invention).

Of these, the roof frame 1 and the window sill frame 2 are integrally formed by casting aluminum or its alloy for mass production, instead of the conventional bending process of steel plates. In addition, the upper and lower frames 3 that constitute the window frame 3
a, 3b and left and right vertical frames 3c, 3d (see Figure 4)
is formed from an extruded profile made of conventional aluminum or an alloy thereof. In this case, in the case of a normal bay window in which the protruding front window part and the left and right side window parts are formed in a straight line in plan view, a shape material that is extruded in a straight line is used as the constituent material of the window frames 3 and 4. However, in the case of a bow window whose projecting surface is curved in an arc shape in plan view, which is the target field of this invention, it is not possible to use the extruded material as is; In particular, the shapes for the upper and lower frames must be bent to the required curvature using a bender. However, when bending a shape material, it is naturally impossible to avoid bending strain, and for this reason, multiple rail protrusions must be precisely installed in parallel on the top and bottom of the window frame, as in the case of sliding windows. In reality, it is impossible to bend the shape material. As shown in Utility Model Application Publication Nos. 56-8780, 56-8781 and 56-10783, proposed by the applicant in the past, in order to fit a fixed glass (fixed window) into the arcuate front window. It can only form the upper and lower frames of . Moreover, even in this case, various considerations must be taken, such as using a split mold, in order to minimize the occurrence of bending strain.

Therefore, if it is difficult to bend the extruded material, it may be possible to form the window frame, especially the upper and lower frames, together with the roof and window sill frames by casting aluminum or its alloy. With a plurality of rail protrusions protruding from the upper and lower frames, it is extremely difficult or impossible to cast them integrally with the roof frame and window sill frame.

(Purpose of the invention) Therefore, the object of this invention is to provide a bow-shaped bay window in which at least the upper and lower frames of the roof frame, window sill frame, and window frame can be molded from aluminum or its alloy castings. It is.

The piece 2b is integrally formed with the mounting piece 2c and the rising piece 2d at the base end.

In addition, at least the upper frame 3a and the lower frame 3b of the window frame 3 of the arc-shaped front window section are also formed of cast aluminum or its alloy, and have rail projecting strips 3a ₁ , 3b ₁ and water return pieces 3a ₂ respectively. A water draining piece _3b2 is integrally formed, and a sealing material receiving piece _3a3 is also integrally formed at the top end of the upper frame. This upper and lower frame 3
A and 3b are each curved to have the same curvature in plan view, and in this case, the window frame 4 in the wing window portion that is not curved may be made of either a cast material or an extruded material.

Then, the upper frame 3a is attached to the window frame attachment part 8 of the roof frame 1,
Further, the lower frame 3b is fixed to each other by screwing screws 10 and 11 into the window frame mounting portion 9 of the window sill frame 2, respectively, and the roof frame 1 and the window sill frame 2 are fixed to each other by the respective mounting pieces 1c and 2c and anchor hardware. 12 and 13 are attached to the building frame 16 by fixing them with bolts and nuts 14 and 15, and each rising piece 1
A watertight treatment is performed by filling the sealing material 17 into the sealing material receiving pieces 3a and d, _2d and the sealing material receiving piece 3a3.

In addition, as for the sliding shoji 7a, 7b, the upper and lower frames 3a, 3b are also curved to the same curvature as described above, but in this case, the upper and lower shoji frames 7a ₁ , 7a ₂ , 7b ₁ , 7b ₂ are thin, and the thickness Since it has a substantially symmetrical shape with respect to the directional center, it can be bent with almost no bending strain, and therefore a general extruded material can be used. Naturally, the window glasses 7a ₃ and 7b ₃ are curved glasses made of glass or transparent synthetic resin.

In FIG. 5, a free mullion 18 is provided at the corner of the arcuate front window frame 3 and the wing window frame 4. This flexible mullion 18 has a thick aggregate part 18a screwed to the upper and lower frames 3a and 3b, and this aggregate part 1.
