A reversible electric motor 21 attached to the machine is fixed to a mounting bracket 22 integrated with the base 2 and connected to one end of the main shaft 18, but a hydraulic motor or other driving means may also be used. Even if it is not directly connected to the above, the purpose can be fully achieved. The driven sprocket 20 is fixed to a mounting bracket 22 that is integrated with the base 2 with a fixture such as a nut 24 at the end of the shaft 23, and the driven sprocket 20 can rotate freely and is connected to the driving sprocket 19. When the rotation of the electric motor 21 is transmitted, the driven sprocket 20 rotates while guiding the engaged chain 8. Although not shown, a pipe 23 is provided above the base 2 to supply a cleaning liquid such as water or soapy water using a pump.

Next, the operation will be explained.

First, the guide shaft 6 has cam joints 12.12 attached to both ends of the guide shaft 6, and the upper rollers 26u, 26u and the protrusion 12.
b, 12b and are stopped in contact with each other above. When the switch is turned on and the electric motor 21 begins to rotate normally, the driving sprockets 19 and 19 begin to move, and the chain 8 suspended between the driving sprocket 19 and the driven sprocket 20 is driven. The chain 8 slides the slider 5 onto the guide 3 and starts moving the guide shaft 6 attached integrally with it downward, and the cam joint 12 slides on the guide shaft 6.
At this time, the wiper brush 11 is moving away from u.
The guide shaft 6, which maintains a substantially right angle to the window glass 30, keeps the brush lid part always in contact with the window glass 30, and is guided by the guide 3, maintains the same distance from the window glass 30, and is moved by the frames lla, 11b. Brush lid with uniform elasticity
In addition, the surface of the window glass 30 is cleaned by the brush lid.The set screw screwed into the screw hole 12x of the cam joint 12 and the ball 12v that elastically suppresses the spring 12s by the set screw are attached. The wiper brush 11 moves the guide shaft 6 in the same way as the slider 5 moves, and wiper brush 11 cleans the window glass 30 surface. You will have to wipe it.

The guide shaft 6 moves downward, and the cam joint 12 moves to the roller 1.
3t, a sensor (not shown) detects the position of the block-shaped slider 5 (if not the slider 5), the rotation speed of the drive sprocket 19 or the driven sprocket 20, and the movement of the wiper brush 11. electric motor 2) is detected, and electric motor 2
Send a stop message to 1. At the same time, the projecting piece 12a of the cam joint 12
contacts the roller 26L and rotates the protrusion 1.2a in the P direction, so the guide shaft 6 to which the cam joint 12 is fixed is rotated in the P direction, the wiper brush 11 is tilted, and the window glass 30 is rotated.
This results in breaking contact between the brush lid and the brush lid. That is, the ball 12v, which was pressed into engagement with the spherical seat 13x of the joint 13' by the set screw and the spring 12s in the screw hole 12x of the cam joint 12, rotates the protrusion 12a in contact with the length of the roller 26 in the P direction. Since it is moved, the engagement between the ball seat 13y and the ball 12v can be changed. Therefore, the guide shaft 6 is connected to the spherical seat 13.
The rotated posture is maintained by the interposition of the ball 12v that engages with y.

As mentioned above, the projecting piece 12a of the cam joint 12 is connected to the roller 26.
When they come into contact again, the cam joint 12 rotates, rotates the guide shaft 6, tilts the wiper brush 11, and the brush lid part separates from the window glass 30 surface. 21 is reversely rotated, and the guide shaft 6, which was in a stopped state, is moved to a state where the cam 12 is separated from the length of the roller 26 and the wiper brush 11 is tilted upward based on the rotation of the drive sprocket 19 of the chain 8. Hold it and move in the upward direction U. At the top,
When the cam joint 12 approaches the roller 26u, the same sensor as described above detects the approach of the block-shaped slider 5, issues a stop signal, and at the same time instructs standby or forward rotation. The guide shaft 6 moves upward, and the cam joint 12 moves to the roller 1.
3u, the protruding piece 12a is pushed and rotated in the Q direction, the guide shaft 6 is also rotated in the q direction, and the wiper brush 11
is perpendicular to the surface of the window glass 30, and the guide shaft 6 returns to its original position and enters the standby state.The guide shaft 6 rotates together with the cam joint 12, and the protrusion 12b of the cam joint 12 Due to the contact between the ball 12v and the roller 26u, the ball 12v is returned to the spherical seat 13x of the joint 13. Therefore, when you want to wipe the window glass 30 surface by moving the wiper brush 11 back and forth several times, follow the push button switch and its circuit provided in the operation box to perform the above-mentioned start-stop, reverse, stop, and wait actions. I will do it. When moving downward, the brush lid of the wiper brush 11 comes into contact with the surface of the window glass 30, and when moving upward, the wiper brush 11
is tilted so that the brush 11d is positioned away from the window glass 30 surface.

The gate-shaped base 2 may be built into the building parallel to the window frame (not shown), but the gate-shaped base 2 should be mounted on a car so that it can be moved and cleaned. Window glass 30, such as a window or a show window
It is also possible to use a movable type that stands close to the room and wipes the area.

This window cleaning device 1 can be driven much faster. Since the sliding movement of the slider 5 is more accurately held parallel to the window glass 30 surface by the guide 3, an average elastic force is applied to the brush lid that comes into contact with the window glass 30, and cleaning I will do it.

(g) As described in detail, according to the present invention, the guide 3.3 is provided parallel to the window glass, and the guide shaft 6 is horizontally mounted on the slider 5.5 which allows the guide 3 to slide. , a cam joint 12.12 is fixed to the guide shaft 6, and rollers 26 are mounted above and below the window glass 30 to engage and contact the cam joint 12.
Since the guide shaft 6 is rotated by the engagement between the roller 26 and the cam joint 12, the wiper brush 11 reliably contacts the surface of the window glass 30, and the rotation of the guide shaft 6 is Accordingly, tilt the wiper brush 11 and remove the brush l.
Only when the id section is separated from the window glass 30 and moved downward, the brush lid comes into contact with the surface of the window glass 30 for wiping, and when moved upward U, the brush lid comes into contact with the window glass 30. Since they do not come into contact with each other, the wiped dirt is not lifted upward, and there is no accumulation of dirt above the window glass 30. Therefore, liquid dirt is wiped from the top to the bottom. , the window glass 30 presents an aesthetic appearance. Although the drive is by the chain 8, the driving force is transmitted to the block-shaped slider 5, and the slider 5
Since the guide shaft 6 slides using the guide 3 as a guide, the guide shaft 6 moves fluidly and smoothly, and the frames 11a and llb provided on the wiper brush 11 apply a balanced elastic force to the brush lid, and the window Promote beautification of glass 30
