DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash frame for a bay window having a drainage path for dew condensation water.

[0002]

2. Description of the Related Art To discharge dew condensation water generated on the indoor side surface of a shoji (shoji) closest to a room from the lower frame to the outdoors, see Japanese Utility Model Publication No. 56-18711 and Japanese Utility Model Application
As shown in No. 60-174785, a hole is made in a part of the prospective piece on the indoor side of the lower frame that receives dew condensation water, and a drainage path is formed to discharge dew water from the prospective piece. Since the receiving part that sandwiches and supports the outdoor end of the main plate is formed in the lower frame like the symbol, if the hole is made in the position of the receiving part, the dew water will flow around to the bottom side of the main plate Therefore, the dew water cannot be directly discharged from the receiving portion.

[0003] The present invention proposes a sash frame capable of discharging dew condensation water from the upper piece to the outside without making a hole in the receiving portion from the above background.

[0004]

According to the present invention, a gap is formed between an upper holding piece constituting a receiving portion having a groove-shaped cross section for supporting an outdoor end of a base plate and a prospective piece of a vertical frame. As a result, the condensed water is discharged through the drainage passage of the lower frame without making a hole in the receiving portion, thereby coping with the generation of the condensed water in the bay window.

The inner peripheral surface of the prospective piece of the vertical frame is continuous with the upper surface of the upper retaining piece of the receiving portion of the lower frame, and a gap is formed between the upper retaining piece and the prospective piece of the vertical frame. The space on the upper holding piece communicates with the space on the prospective piece of the lower frame.

[0006] A drainage path is formed from the prospective piece located below the receiving portion of the lower frame to discharge dew condensation water to the outside through a finding piece located outside the room. Condensation water generated on the shoji and dropped on the upper holding piece, or condensed water generated on the inner peripheral surface of the prospective piece of the vertical frame falls from the gap between the upper holding piece and the prospective piece of the vertical frame onto the prospective piece below it Drops and is discharged outdoors. The condensed water that has fallen on the upper holding piece is dropped onto the prospective piece below without going around the room side, so that no influence is exerted on the main plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, the present invention relates to a prospective piece 22 located below a receiving portion 21 for supporting an end of the lower frame 2 on the outdoor side of the base plate 5, and a finding piece located on the outdoor side. This is the sash frame 1 of the bay window in which the drainage path for discharging the dew condensation water to the outside through 23 is formed.

The receiving portion 21 of the lower frame 2 has a groove-shaped cross section formed by an upper holding piece 211 and a lower holding piece 212 which are vertically arranged in parallel, and the upper surface of the upper holding piece 211 is formed in the vertical frame 3 as shown in FIG. It is continuous with the inner peripheral surface of the prospective piece 31 located near the periphery. As shown here, a slight gap 4 is formed between the upper holding piece 211 and the prospective piece 31 of the vertical frame 3, and the upper holding piece 21
1 The upper space and the space on the prospective piece 22 of the lower frame 2 communicate with each other.
The gap 4 is formed such that one end of the upper holding piece 211 and the prospective piece 31 abuts on the other inner peripheral surface, or both ends abut as shown in the drawing.

The condensed water generated on the shoji and dropped on the upper holding piece 211, or the condensed water generated on the prospective piece 31 of the vertical frame 3 and falls through the gap 4 as shown in FIG. It is drawn into the space side on the prospective piece 22 and falls on the prospective piece 22. A drainage port 24 is opened in the finding piece 23 located on the outdoor side of the prospective piece 22, and after the dew condensation water on the prospective piece 22 is guided to the outdoor side from the drainage port 24 or further through the hollow portion of the lower frame 2. Discharged outdoors.

As shown in FIG. 2, a step is provided on the indoor side of the prospective piece 22 and a supporting portion 25 which is higher than the upper surface of the prospective piece 22 and on which the bottom surface of the base plate 5 rests is formed. Department
It is supported by the lower frame 2 at 25. The outdoor end of the base plate 5 is protected by the resin cover 10, and the attachment 11 attached to the outside of the base plate 5 is supported by the receiving portion 21 by being sandwiched between the holding pieces 211 and 212.

The upper surface of the support portion 25 serves as a guide when the base plate 5 is slid from the indoor side by setting the upper surface to a horizontal plane. , And an engaging member 9 fixed to the bottom surface of the main plate 5. Ground plate 5
Is installed while maintaining a horizontal state by vertically sandwiching an engaged piece 81 in which the engaging member 9 protrudes toward the indoor side of the receiving member 8, and the engaging member 9 is positioned above the engaged piece 81 after installation. By stabilizing against floating or warping by engaging with.

FIG. 3 shows the receiving member 8 and the engaging member 9 shown in FIG.
4 or 5 in the form of a combination of
12 shows a case where the base 12 is fixed to the indoor side of the support portion 25, the upper surface of the support member 12 is used as a guide when the base plate 5 slides, and the base plate 5 is directly supported after installation. The base plate 5 rests on a mounting piece 121 projecting toward the indoor side of the support member 12,
By being joined to the mounting piece 121, it is stabilized against lifting and warping. The chain line in FIG. 3 indicates the ground plate 5 having a small thickness.

Since the lower frame 2 of the bay window projects from the opening to the outside, when a drain path is formed, the drain port of the find piece 23 is formed.
Since there is rainwater blowing from 24, or backflow of dew condensation water, an airtight material pocket 26 is formed on the outdoor side of the support portion 25 to prevent these waters from going around the indoor side from the support portion 25, An airtight material 6 that adheres to the bottom surface of the base plate 5 is laid on this.

When the cover 7 is placed under the bottom of the lower frame 2 as shown in FIG. 2, the condensed water that has fallen from the drainage port 24 of the finding piece 23 is discharged through the cover 7.
In order to prevent intrusion into the room due to backflow on the cover member 7, a water blocking piece 71 is provided on the room side at a position where it falls from the drain port 24.
Is formed.

[0015]

As described above, the present invention is directed to an upper holding piece constituting a receiving portion for supporting an outdoor end of a main plate;
A space is formed between the prospective piece of the vertical frame and the space on the upper holding piece and the space on the prospective piece of the lower frame are communicated with the gap in between, and the dew water is discharged through the drainage route of the lower frame. In addition, it is possible to discharge the dew condensation water without making a hole in the receiving portion of the bay window, and does not affect the main plate.
