(Prior Art) Window cleaners for high-rise buildings are either hung from the roof with robes and the person cleaning them hangs from the robes to clean the window glass, or they are called gondolas, which are hung from both sides with robes. It was common for the person cleaning the windows to ride on the gondola's l while hanging a robe to clean the window glass.

However, these conventional methods are not only expensive, but also
Because of the dangers involved, fewer people are taking up these jobs.

(Problems to be solved by the invention) Conventional window cleaners for high-rise buildings require humans to perform dangerous work, and cleaning an entire building costs 4 to 5 million yen each time. was on.

For this reason, it was common for subcommittees to clean the window glass only once a month, even if dust and dirt from crystals from exhaust gas had accumulated on the window glass.

In the present invention, in order to solve these problems, the bucket containing the cleaning brush can be moved up and down to clean the window glass by simply turning on the power when necessary.

(Means for Solving the Problems) The present invention relates to a window cleaner that cleans windows attached to the outer wall of a high-rise building by touching a cleaning brush from the outside and moving it up and down. A work opening/closing plate 1 is provided at the rear, and an inspection opening/closing plate 2 is provided at the rear, and a bucket cover 6 for housing a bucket 5 having a built-in cleaning brush 4 linked to a motor 3 is fixed to the bottom of the beam 7. The lifting pinion gears 10 at both ends of the cleaning brush 4 inside the bucket 5 are screwed into the rack gears 9 of the guide rail 8 hanging from both walls inside the bucket cover 6 to move the guide rail 8 up and down. This is a window cleaner for a high-rise building, which cleans a window by bringing it into contact with a window aligner 11.

(Function) In the present invention, the spiral type cleaning brush 4 disposed on the rotary shaft 13 built into the bucket 5 shown in FIG. The rack gear 9 adjacent to the sash 15 is rotated by the lifting pinion gear 10 driven by the lifting geared motor 21 to clean the window glass while rotating through the rack gear 14.
The bucket 5 cleans the window glass 11 while moving up and down while meshing with the window glass 11.

A rubber spatula 12 is provided protruding from the bucket 5, so that large pieces of dirt and the like on the window glass 11 can be scraped off.

The cleaning brush 4 is of a spiral type, which is intended to reduce the weight of the bucket 5 and to make it easier to drop dirt and dust to the bottom of the bucket 5.

To explain the work procedure in Fig. 2, open the inspection opening/closing plate 2 of the bucket cover 6 fixed under the beam 7, and press the operation switch 16 built in the bucket cover 6. Push open/close plate 1 and release it.

The elevating gear motor 21 of the kite 5 is started, and the bucket 5 slides on the kite rail 8 by rotation of the elevating pinion gear 10 and moves downward while rotating the cleaning brush 4.

The rubber spatula 12 protruding from the bucket 5 is the window guard 11.
The cleaning brush 4 rotates and slides while cleaning the window glass.

FIG. 1 shows a state in which the bucket 5 opens and closes the working opening/closing plate 1 of the bucket cover 6, slides on the guide rail 8, and moves to the middle part of the window.

To explain this with reference to FIG. 4, the lifting pinion gear 10 that meshes with and interlocks with the rack gear 9 of the guide rail 8 moves the bucket 5 up and down by the rotation of the lifting geared motor 21, and the cleaning brush drive motor 3 is rotated. The transmission belt 14 is driven to rotate the rotary shaft 13, and the cleaning brush 4 cleans the window glass 11-4- fixed to the sash 15 while rotating.

FIG. 5 is a partial schematic view of the bucket 5, in which the rotation of the cleaning brush drive motor 3 drives the transmission belt 14 and rotates the rotating shaft 13.

At the center of the elevating pinion gear 10 is a shaft 18 that is interlocked with an elevating gear motor 21 and moves the bucket 5 up and down.

FIG. 6 is a side view of the geared motor for lifting. Rotation of the geared motor for lifting 21 drives the transmission belt 22 to rotate the pinion gear for lifting along with the shaft 18, which meshes with the rack gear 9 of the guide tool 8. Then, the bucket 5 is moved downward by -L.

The bucket stabilizing roller 19 installed at the bottom of the bucket 5 not only prevents the bucket 5 from tilting due to its own weight and the cleaning brush 4 from separating from the window octopus h), but also improves safety. This has been taken into consideration.

FIG. 7 is a sectional view of the bucket 5 taken along the line AA, in which a cleaning brush driving shaft 20 is disposed on the outer periphery of the shaft 18 via a bearing 17 for smooth rotation, and is fixed to the cleaning brush driving shirt 1-20. A cleaning brush 4 is fixed to the rotating shaft 13.

It goes without saying that the cleaning brush 4 is not limited to the spiral type shown in FIG.

Figure 9 shows bucket 5 on the geared motor side for cleaning brush operation.
, the transmission belt 14 is driven by the rotation of the cleaning brush drive motor 3 to rotate the cleaning brush driving shaft 20 and rotate the cleaning brush 4 fixed to the rotating shaft 13. It has become.

FIG. 8 is a bottom view of the beam portion, which is the portion where the bucket cover 6 of the present invention is attached.

A bucket cover 6 is attached to a fixed stay on the upper part of a sash 15 fixed to a beam 7.

Furthermore, as shown in FIG. 2, an opening/closing tool 23 for opening or closing the working opening/closing plate 1 in conjunction with the working opening/closing plate 1 is installed in the housing of the bucket cover 6, so that the bucket 5 can be opened or closed. It is now possible to open and close smoothly when starting and finishing work.

Of course, even if the opening/closing tool 23 is not used, the nine work opening/closing plates 1 can be freely opened and closed by pressing the operating switch 16.

Since dirt and dust can be easily dropped to the bottom of the bucket 5, open the inspection opening/closing plate 2 and remove the dirt and dust from the bucket 5.
