In fittings with a stepped window structure, it is desired to unify the position of the glass surface material of the window in the prospective direction in the upper and lower steps to achieve a unified appearance of the window. Further, in order to achieve a unified appearance of the building and to secure a large space on the indoor side, it is desired to provide the position of the glass surface material of the window in the prospective direction closer to the outside of the frame.

The opening / closing mechanism operates while supporting the window. Therefore, in order to ensure the load bearing capacity of the opening / closing mechanism, it is desirable to install it directly above the window. Further, in order to support the upper window provided above the transom light frame, it is desirable to provide an opening / closing mechanism on the extension line of the glass surface material of the upper window. Therefore, when the position of the glass surface material is provided closer to the outdoors in the prospective direction, it is preferable to provide the opening / closing mechanism in the vicinity of the end portion on the outdoor side in the prospective direction of the transom light frame. On the other hand, in order to enhance the water blocking function, it is preferable to provide a draining material or a water blocking material that suppresses the infiltration of rainwater into the fittings in the vicinity of the end portion on the outdoor side in the prospective direction of the transom light frame. However, it was difficult to consolidate the opening / closing mechanism, the draining material, and the water blocking material into a part of the outdoor side in the prospective direction of the transom light frame.

In view of the above circumstances, it is an object of the present invention to provide fittings in consideration of appearance design and water blocking performance.

The fitting according to the present invention is a fitting having a stepped window structure in which two or more windows are arranged side by side in the vertical direction, and is provided in parallel with a frame formed by a vertical frame and a horizontal frame and the horizontal frame. , A transom light frame erected between the pair of the vertical frames, a vertical window provided below the transom light frame and configured to rotate around the vertical axis and open / close, and the transom light frame. It is equipped with an opening / closing mechanism that is attached and supports the vertical window so that it can rotate around the vertical axis, and a drainage material that is provided in the transom light frame and prevents water from entering the window from the outside to the inside. The drainage material is characterized in that it is provided on the indoor side in a prospective direction with respect to the opening / closing mechanism.

According to the present invention, since the draining material is provided on the indoor side of the opening / closing mechanism of the vertical window, the opening / closing mechanism can be arranged on the outdoor side of the draining material. Therefore, the vertical window that can be opened and closed by the opening / closing mechanism can be arranged on the indoor side, a sense of unity in the appearance of the building can be obtained, and a stepped window having an excellent appearance design can be provided. In addition, the drainer can prevent rainwater from entering the indoor side of the vertical window. As a result, it is possible to provide fittings in consideration of appearance design and water blocking performance.

In the fitting according to the present invention, the transom light frame includes an extension piece that extends downward from the outdoor end of the transom light frame and covers a fixed portion between the transom light frame and the opening / closing mechanism. May be good.

According to the present invention, the extension piece covers the fixed portion between the transom light frame and the opening / closing mechanism, so that the extension piece functions as a protective wall for water, light, and wind. In addition, the gap between the transom light frame and the vertical window can be covered. As a result, deterioration of the opening / closing mechanism due to water or light can be prevented, and a fitting having excellent durability can be provided.

In the fitting according to the present invention, the opening / closing mechanism may be provided on an extension of the glass surface material of the vertical window and the glass surface material of the upper window provided above the transom light frame.
