SUMMARY OF THE INVENTION It is an object of the present invention to provide fittings capable of securing a large amount of ventilation while reducing the width of the protrusion to the indoor side when the door is opened.

In order to achieve the above object, the fitting according to the invention of claim 1 includes an opening for ventilation provided in the shoji and an inward-folding door that opens and closes the opening, and the door has an indoor side wall on the outdoor side. A hinge portion is provided at the tip thereof, the hinge portion is connected to the hinge portion receiver of the horizontal member of the shoji, and a dew condensation water receiver is provided adjacent to the lower side of the hinge portion receiver. The receptacle has a concave shape with an inclined wall that slopes downward from the hinge receptacle toward the room interior . A tight part is provided between the outdoor side surface and the horizontal member.

The fitting according to the invention of claim 1 is provided with an opening for ventilation provided in the shoji and an inward-folding door that opens and closes the opening. By connecting the hinge part to the hinge part receiver of the lateral member of the shoji, the door can be opened at a large opening angle with a small extension width, so that a large amount of ventilation can be secured. Moreover, since the condensed water receptacle is provided below and adjacent to the hinge part receptacle of the horizontal member, even if dew condensation occurs on the door, the condensed water will not drip on the shoji. Furthermore, a tight part is provided between the vertical part of the indoor side wall of the door and the horizontal member, so that the door is excellent in watertightness and airtightness.

The door 3 is designed to be tilted 45 degrees toward the room side. As mentioned above, by setting the hinge part 5 near the center of the shoji 1b in the prospective direction, the door 3 can be opened at a large opening angle with a small extension width, and as a result, a large amount of ventilation can be obtained. can.

5 to 7 show other embodiments of fittings according to the present invention. In this embodiment, a ventilation device 19 is provided along the inner peripheral side of the lower frame 15 of the inner shoji 1b. In this case, as shown in FIG. 6, the upper horizontal member 20 constituting the opening 2 is provided with a hollow portion 51 and a glass holding groove 36 on the inner peripheral side thereof, and the lower horizontal member 6 is provided with the glass of the lower frame 15. A pair of locking pieces 26, 26 to be inserted and locked into the holding groove 25 are provided. Other than that, the structure is the same as when the ventilator 19 is provided on the upper frame 14 side.

As described above, this fitting includes an opening 2 for ventilation provided in the shoji 1b and an inward-folding door 3 that opens and closes the opening 2. The door 3 has an indoor side wall 4 bent to the outdoor side. A hinge portion 5 is provided at the tip thereof, and the hinge portion 5 is connected to the horizontal member 6 of the shoji 1b, so that the door 3 can be opened at a large opening angle with a small extension width, thereby increasing the amount of ventilation. can be taken large. Further, a tight portion (tight material 7b) is provided between the vertical portion 4a of the indoor side wall 4 of the door 3 and the horizontal member 6, so that watertightness and airtightness are excellent.
In addition, since this fitting has a condensed water receptacle 24 adjacent to the lower horizontal member 6 forming the opening 2 below the hinge part receptacle 39 for receiving the hinge part 5, even if dew condensation occurs on the door 3, the condensed water does not hang down on the shoji 1b.
Furthermore, in this fitting, the main body of the ventilation device 19 (the portion of the door 3 excluding the operation portion 23) is accommodated within the estimated dimension A of the shoji 1b, so the ventilation device 19 does not get in the way and the design is good. .

The invention is not limited to the embodiments described above. The length and angle of the bent portion of the door and the form of the hinge portion can be changed as appropriate. The hinge portion of the door can also be directly connected to the lower frame of the shoji. The tight portion between the vertical portion of the indoor side wall of the door and the lateral member can also be constructed by attaching a tight member to the door side. The composition of the shoji and the frame is arbitrary. The shoji may be a shoji that is fixed to a frame. The present invention is not limited to double sliding windows, but can be applied to any fittings such as single sliding windows, casement windows, and entrance doors. Moreover, it goes without saying that the present invention can be applied not only to fittings for renovation but also fittings to be newly installed.
