The upper part 14 of the connecting piece 16 provided with is located, and the shaft 17 installed in both the hanging pieces 13 and 13' passes through the hole provided in the upper part 14, and the connecting piece 1
3.13' and both end surfaces of the upper part 14 are respectively provided with push springs 18.

In addition, the lower part 15, which is perpendicular to the upper part 14, is formed by the vertical pieces 20 and 20 on both sides of the second mounting plate 19, which is formed in an upward U-shape.
The shaft 21 located between the two side uprights 20.20' passes through the hole provided in the lower part 15 and connects to the both side uprights 20.20' in the same way as in the case of the upper part 14. Push springs 22 are disposed between both end surfaces of the lower portion 15, respectively.

A wiper member 23 is installed between the lower ends of the second mounting plates 19 installed on both sides of the box body 2 configured as described above.
The rice wiper member 23 has a frame member 27 having upper and lower plates 25 and 26, and a frame member 27 whose rear end and both side ends are closed and whose front face is open. A water-containing material such as a sponge that extends in the length direction 2
8, and a large number of water holes 29 provided at the front end of the water-containing material 28 and penetrating in the front-rear direction are spaced apart in the longitudinal direction, and the sliding brush 30 on the glass surface protrudes from the opening. A fixing part 31 is provided which is buried along the length of the base, and an upper mounting part 45 is provided on the front part of the upper surface of the upper plate 25.
At the front of the lower surface of the lower plate 26, upwardly inclined lower mounting portions 46 are provided at a required distance from the lower surface of the lower plate 26.
7, the upper and lower mounting portions 45.
46, elongated upper and lower scrapers 3 made of a flexible material such as rubber whose tips almost match the tips of the brush 30;
2. Attach the base of 33 respectively.

Reference numeral 34 denotes a cleaning water storage tank provided in the upper part of the box body 2, and a solenoid valve (not shown) is connected between this storage tank 34 and the rear part of the space formed by the upper and lower plates 25 and 26. The space 35 formed between the lower plate 26 and the lower mounting part 46 and the sewage tank 36 provided at the bottom of the box body 2 are connected by a water pipe 47. communicated by.

37.37' is a reversible drive member attached to the rear protrusion 4 of the substrates 5, 5', and this drive member 37.3
An endless chino 40 is stretched between the sprocket 39 provided on the output shaft 3b of 7' and the sprocket 8 provided on the screw shaft 6.

The front surface of the box body 2 has an opening 41 large enough to allow the first mounting plate 12 and the wiper member 23 to enter and exit, and the rear plate 43 can be removed with screws 49.

Therefore, the window glass cleaning device 1 configured as described above
is suspended from a cable from a winder installed on the roof of a building, and is run along the wall of the building by the drive of the winder.

When both drive members 37 and 37' are driven synchronously during this traveling process, the substrate 5,
The screw shaft 6 installed at 5' rotates.

This rotation causes the driving member 9 and the sleeve 10 fitted on the guide shaft 7 to move together, and the connecting member 16 , which is integrally attached to the sliding member 9 via the first mounting plate 12 . The second mounting plate 19 and wiper member 23 also move together.

In this case, drive members provided on the substrates 5, 5' on both inner surfaces of the box body 2 are driven so that the front end of the wiper member 23 is brought into contact with the outer surface of the window glass with an appropriate contact pressure.

Then, with the top and bottom scrapers 32, 33 of the wiper member 23 and the tips of the brush 30 in contact with the outer surface of the window glass, the electromagnetic valve is operated to temporarily impregnate the water-containing material 28 with the cleaning water in the storage tank 34, The cleaning water impregnated into the water-containing material passes through the water passage hole 29 to the brushes 30, and the brushes 30 are placed in a water-containing state.

In this state, when the device is raised and lowered by the winder, the upper and lower scrapers 32 and 33 and the brush 3 containing cleaning water are removed.
The filth and dust adhering to the glass surface are scraped off by the cleaning water, and the filth and dust are guided into the empty space 35 of the wiper member 23 along with cleaning water, and then transferred to the sewage tank 36 located at the bottom of the box body 2. will be collected within.

In the above, since the connecting piece 16 is elastically held in the direction perpendicular to the window glass by the push spring 18, even if the wiper member 23 is slightly out of parallel with the window glass in its length direction, Also, the distal end surface of the wiper member 23 can be brought into uniform contact with the glass surface in its length direction, and displacement in the direction parallel to the window glass can also be effectively countered by the action of the push spring 22. It is something.

In this way, when moving to another window glass after cleaning one window glass, for example, if there is a protrusion on the outer wall of a building, both drive members 37 and 37' are driven synchronously to wipe the wiper member. 23 moves backward into the box body 2, and the wiper member 23 is moved forward again in the same manner as described above to bring the tips of the upper and lower scrapers 32, 33 and the brush 30 into contact with the outer surface of another window glass. It is.

Therefore, when there is a protrusion between the window glasses, the wiper member 2
3 can be prevented from colliding with a protrusion and breaking it.

In the above embodiment, drive members are provided on the substrates 5 and 5' provided on both inner surfaces of the box body 2, but one drive member is omitted and the output shaft of the other drive member is replaced with the drive member. Of course, if the screw shaft on one drive member side is connected, the wiper member can be moved forward and backward by one drive member.

As mentioned above, this idea was designed to move the wiper member forward and backward from the box suspended from the window glass at a predetermined distance so that the tip of the wiper member comes into contact with the window glass surface, or to prevent collisions with protrusions on the wall of the building. The wiper member is convenient for cleaning the window glass surfaces of buildings, and since both ends of the wiper member are held elastically, the wiper member can be brought into even contact with the window glass. Furthermore, since the used washing water, filth, and dust are recovered, it has the advantage that wastewater treatment is easy.
