Since the outer outer surfaces 58b, 59b and outer lower and upper surfaces 61b, 63b of 59, 61, and 63 are sloped surfaces, there is no possibility of dust etc. accumulating, and if dust etc. accumulates, the sloped surfaces It is always maintained in a beautiful condition as rainwater that flows along it is removed.

As shown in FIG. 12, the distance between the vertical walls 60, 60 of the intermediate horizontal members 51, 51 of the grid-like panels 50, 50 attached to the interior and exterior of the glass 7, that is, the width in the interior and exterior directions. W, upper and lower middle horizontal member 5
1, the distance between the lower horizontal wall 59 of 51 and the upper horizontal wall 58;
In other words, it is set so that H/W<tanθ, where H is the vertical distance between the horizontal members and θ is the minimum angle of incidence of sunlight with respect to the horizontal line.

In other words, when the incident angle of sunlight is the minimum incident angle θ, the sunlight hits the lower corner D of the outdoor upper horizontal member 51 and does not enter the interior, and when the incident angle is larger than the minimum incident angle θ, the sunlight hits the lower corner D of the upper horizontal member 51 on the outdoor side and does not enter the inside. The sunlight passes through the upper corner E of the lower horizontal member 51 on the indoor side and is irradiated onto the upper surface of the upper horizontal wall 58 on the outdoor side, and the sunlight is prevented from being directly irradiated on the indoor side through the glass 7. be.

For this reason, it is possible to reduce deterioration of the indoor side due to sunlight, and it becomes more difficult to visually see the indoor side than the outdoor side.

In addition, in the above example, a parent door and a child door were used with front and back panel units attached, but an inward opening window is used in which a pair of doors with only glass or panels attached to the door frame so as to be rotatable toward the indoor side. Of course, it is good to do so.

Effects of the invention The outdoor side joint sealing material can maintain the airtightness and watertightness of the outdoor side of the joint part, and the upper and horizontal sealing materials are evenly pressed against the outdoor side surface of the upper stile of the pair of doors from the upper notch of the outdoor side joint piece. It is possible to maintain airtightness and watertightness between the upper frame and the outer side of the upper stile room of the pair of doors.

Since the upper notch of the outdoor matching piece can be covered with the tip of the hanging piece, it is not visible from the outdoor side and the appearance can be improved.
