2. Description of the Related Art Since dirt from the outside air adheres to a window glass, the dirt is regularly wiped off. However, if it is a window structure of a wooden building like the old days with about 2 to 3 floors,
It was possible to wipe the glass on the outside while staying inside the room, but in the case of high-rise buildings like in recent years, it is no longer possible to wipe the window glass of your own office. First, it is expensive and dangerous, and one windowpane becomes very large, and even if you extend your arm, you cannot wipe the entire windowpane.

Therefore, it is necessary to request a window glass cleaning company for such high-rise buildings.
As is well known, window wiping of high-rise buildings is carried out by suspending a gondola from the roof and riding the gondola. The gondola is suspended by pulling out the wire wound around the drum installed on the rooftop, but it sways when the wind blows, especially if the suspended wire becomes long, this sway is large, and of course there is danger. . Since the window glass wiping work may be dangerous, the cost thereof is considerably high. Therefore, it is often the case that the window glass wiping cannot be performed.

Recently, an automatic window glass wiping device is partially used instead of an operator placing the gondola on the window to wipe the window glass. By using the automatic window glass cleaning device, there are great advantages such as elimination of danger, reduction of running cost, shortening of working time, etc., but basically, the conventional gondola is equipped with the window glass cleaning device. , The device must have a guide rail for moving up and down along the side wall of the building, it is not ready to attach the guide rail to the existing building, and the wall is curved. In such a unique building, such an automatic window cleaning device cannot be used.

[0005]

As described above, the window glass wiping operation using the gondola has the above-mentioned problems. The problems to be solved by the present invention are these problems, and the window glass can be freely wiped at any time, and it can be attached to an existing building without being influenced by the style of the building. Provided is a sash equipped with an automatic window cleaning device.
