[0002]

2. Description of the Related Art Conventionally, when cleaning window glass or show window glass, a cloth or sponge has been used to wipe the glass. However, after applying a cleaning solution such as water or a cleaning agent to the glass, the glass is wiped dry. And it was very complicated and inefficient. The outer surface of the windowpane (outside surface) is particularly dirty, but in high-rise buildings, etc., the windowpane is installed at a high place, and it is necessary to get out of the windowpane and clean the outside of the windowpane. It was very dangerous work. Also, depending on the location, the outer surface of the window glass is located in a place that is difficult to reach, such as a narrow place, and it is difficult to clean the window glass.

Therefore, US Pat. No. 3,296,645 and related US Pat. No. 3,751,750 and US Pat.
No. 9793 states that in cleaning windows at high altitudes,
A window cleaning device that can reduce the risk has been proposed. This window cleaning device is formed of a master unit and a slave unit magnetically attached through a window glass. When the master unit is moved along the indoor surface of the glass, the slave unit follows the movement of the glass unit. It is designed to move along the outdoor surface.
By moving cloth and paper or paper coated with detergent between the parent machine and the other surface of the glass, the parent machine and the child machine are moved. , Both surfaces of the glass can be wiped and cleaned.

Japanese Patent Laid-Open Publication No. 53-96264 discloses a glass cleaner having a higher cleaning ability than the above-mentioned window cleaning device. This glass cleaner is provided with a closing plate at the upper end of the outer casing of the cleaner and at the lower side of the closing plate of the outer casing of the cleaner with a cleaning medium for containing the cleaning liquid. A magnet is provided between them to form a cleaner, and two cleaners are configured as one set.

[0005] In this glass cleaner, one cleaner is magnetically attached to another cleaner through a window glass, and one cleaner is moved along the indoor surface of the glass so that the cleaner follows the other cleaner. Is moved along the outdoor surface of the glass to clean both sides of the glass. This glass cleaner supplies a cleaning liquid from the cleaning medium to the surface of the glass, and lifts up dirt attached to the glass with the cleaning liquid.
The glass can be cleaned by scraping and collecting dirt with the cleaning plate from the surface of the glass together with the cleaning liquid,
The cleaning ability is high.

[0006] In the above-mentioned publication, a cord for preventing falling is provided on a slave unit or a cleaner used outdoors.
The string is connected to a master unit or a building to prevent a slave unit or a cleaner used outdoors from falling.

[0007]

However, in the above-mentioned prior art, although the slave unit or the cleaner used outdoors can be prevented from falling, the impact upon hitting a person is large, and the traffic on the downstairs can be prevented. There was a problem that there was much danger to humans. In addition, since the strap is provided with the fall-preventing cord, the cord is entangled, and the parent machine, the child machine, or the cleaner becomes difficult to handle, and thus there is a problem that the working efficiency is reduced.

The present invention has been made in view of the above points, and can reduce the danger given to a person who is below a place where a glass cleaning operation is performed, such as a pedestrian downstairs. It is an object of the present invention to provide a glass cleaning device capable of preventing a reduction in work efficiency.
