c. It is fixed to the lintel 1, and the upper mounting bracket 30 is firmly fixed to the upper frame 4, and the indoor side surface 38a of the mounting piece 38 is slanted to attach the fixing member 40 to the mounting vertical wall of the upper frame 11. 11a so that it can be screwed diagonally from below on the indoor side.

The upper horizontal cover 32 is a long material bent into a hook shape by a vertical piece 41 and a horizontal piece 42.
The locking recess 43 engages with a locking piece 44 formed on the indoor wall 4a, and the horizontal piece 42 engages with the fastener 4.
5 is fixed to the bracket 31, and this upper horizontal cover 32 covers the upper mounting bracket 30 and fixing members 39, 40.

A downward U-shaped base plate support 46 is fixed to the connecting wall 5c of the lower frame 5 with a fixing member 47, and a base plate 48 is placed on the horizontal piece 46a of the base plate support 46, which is horizontal. The fixing member 47 is screwed onto the outer lower rail 10, and an auxiliary support 49 is fixed to the outer vertical piece 46b of the base plate support 46.

With this configuration, the base plate 48 can be easily attached.

The vertical mounting frame 12 has inner and outer vertical walls 12a and 12b connected by a connecting wall 12c to form first and second recesses 12 ₁ and 12 ₂ that are open to the interior and outside, and the inner vertical wall 12a has a fishing shape. A bent wall 12d is integrally formed, and an outwardly directed abutment piece 12e is integrally formed on the outer vertical wall 12b.

The vertical mounting frame 12 is connected to the vertical frame 6 via a plurality of piece-shaped vertical mounting fittings 50.

The vertical mounting bracket 50 is fixed to a first vertical mounting bracket 54 that is L-shaped with one side piece 52 and the other side piece 53 connected to the vertical column 3 from the connecting wall 6c with a fixing member 51, and the other side piece 53. It consists of a U-shaped second vertical mounting bracket 56 fixed with a fixture 55, and the second vertical mounting bracket 56 is tightly fitted into the first recess 121 of the vertical mounting frame 12, and the _second vertical mounting bracket 56 is fixed with a fixture 57 to the outside vertically.

58 is a vertical cover, which includes one side piece 59 and the other side piece 6.
0 to form an L-shaped elongated member, and the locking recess 61 of the one side piece 59 engages with the locking piece 62 of the indoor wall 6a, and the other side piece 60 is fixed to the bending wall 12d. The first and second vertical mounting brackets 54 and 56 and the fixing fixture 51 are fixed by a vertical cover 58.
It covers 55.

In FIG. 2, the symbol 70 indicates the upper and lower cross members 13, 1.
The head 70 of the connecting bolt is inserted into the vertical mounting frame 12 and the vertical mounting frame 15 and tightened, and the head 70 of the connecting bolt is housed in the first recess ₁₂₁ and is connected to the second vertical mounting bracket. 56 so as not to interfere with it.

Effect of the invention The upper mounting frame 11 is attached to the upper frame 4 of the existing window frame via the upper mounting bracket 30, and the vertical mounting frame 12 is attached to the first and second
Since it is attached to the vertical frame 6 via the vertical mounting brackets 54 and 56, the bay window C can be installed without any processing on the outdoor surface of the opening A.
can be easily installed using an existing window frame, and the installation strength can be increased.

Upper mounting bracket 30, first and second vertical mounting brackets 54,
56 is covered with the upper horizontal cover 32 and the vertical cover 58, so it is not visible from the indoor side, resulting in an excellent appearance.

Further, the mounting piece 38 of the upper mounting bracket 30 is substantially flush with the outdoor side wall 4b of the upper frame 4, and the mounting piece 38 and the outdoor side wall 4b are attached to the mounting vertical wall 11a of the upper frame 11.
Since the upper mounting frame 11 is firmly attached to the outdoor side wall 4b of the upper frame 4a and protrudes forward, the vertical mounting frame 12 is attached to the second vertical mounting bracket. 56, first vertical mounting bracket 5
4, and the mounting surfaces of the first and second vertical mounting brackets 54 and 56 are substantially flush with the outdoor side wall 6b of the vertical frame 6, so the mounting vertical frame 12 is connected to the vertical frame 6. It is firmly attached to the frame 6 so as to protrude forward from the outdoor side wall 6b.

Therefore, since the bay window can be firmly attached while protruding forward from the upper frame 4 outdoor side wall 4b of the existing window frame and the vertical frame 6 outdoor side wall 6b, the length of the bay window protruding from the existing window frame can be increased.

Since the vertical mounting frame 12 has a recess that opens toward the indoor side, the head 70 of the connecting bolt that has been inserted through the upper and lower horizontal members 13 and 14 and tightened between the vertical mounting frame 12 and the vertical frame 15 is inserted into the recess. the head 70
Since it does not get in the way when connecting to the vertical frame 6, and the second vertical mounting bracket 56 is provided in the recessed part, the strength of the vertical mounting frame 12 itself can be reinforced with the second vertical mounting bracket 56, and the bay window The rigidity can be increased.
