! VEHICLE WASHING MACHINE

The invention relates to a vehicle washing machine as defined in the preamble of claim 1.

j There are prior art vehicle washing machines with side brushes which separate the vehicle from the side of the vehicle. When the widths of the vehicles vary, the brush equipment must have a movement towards the side of the vehicle for narrower vehicles and a return movement for the wide vehicle. Such a known brush and frame assembly is implemented using transfer guides in the transverse direction of the vehicle.

In this case, the washing machine takes up a lot of space in the washroom, also sideways, since at 2.6 m wide, the space for the washing machine easily becomes 7 m wide.

To overcome these drawbacks and to provide an improvement over the prior art, the present invention has provided a novel washing machine which solves the above problems. The invention is characterized by what is stated in the claims.

The advantage of the invention may be firstly the small space requirement during the washing operation, the possibility of turning the apparatus: / ·: to the side when not in use, the simplification of the washing machine body, since the bodies can be completely separate in different parts of the washing vehicle. The equipment is suitable as well as the laundry. ** ·. the type where the vehicle is driven slowly through the machine;

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which * (I ·

Figure 1 shows a vertical rotatable brush 1 for washing one side of the vehicle. The brush 1 is in a fully retracted position and supported by a chassis to the floor of the washroom and e.g. by a chassis 5 to the ceiling.

Figure 2 shows a situation in which the brush 1 has been moved to the outermost position. The brush is supported by a brush beam 7, the ends of which are rotatably mounted on the brush. The vertical frame of the washing machine is a beam 8, from which the transfer and support arms 9 extend to the beam 7. At the top of the beam 8 is a sliding beam 3 supporting the brush system, on which the brush body 7 slides through the sleeve part 4. The arms 9 are articulated in the beam 7 and the other end is movable along the beam 8 on a special sliding unit 12. The sliding units 12 are secured to a strap 11 by means of which the units 12 are moved in the beam 8 so that the arms 9 either push out the brush assembly or pull closer to the beam 8. 7.

: The beam 8 is pivotable about its longitudinal axis by at least 90 ° so that the brush assembly attached thereto pivots to the side. The turning is effected, for example, by the power unit 6 with respect to the frame 5. The power unit also keeps the brush assembly right during washing. in the direction of L as shown in Figure 4.

Figure 3 shows in greater detail the arm mechanism that moves. bar 7 further and closer. 11 straps of the timing belt »·! '.! slider units 12 are also moved around the drive wheel 13 ;;;; which are attached to the belt 11 up and down when the beam 7 and ··· 'brush are to be zoomed in and out. The toothed belt 11 is preferably a closed loop which, for example inside the beam 8, returns to the drive wheel.

Figure 4 is a top view of the brush assembly. The drive motor and gear of the toothed belt are part 14. The rotation motor of the brush 1 is part 2 and the line L represents the direction of movement of the brush in the washing situation. Broken-ν ': The line shows the position of the brush turned to the side.

Figure 5 illustrates a brush arrangement at the outermost wash station 110246 3, corresponding to the situation of Figure 2.

If the arm arrangement 9,10 does not achieve a sufficient brush travel distance relative to the width of the vehicle to be washed, i.e., the brush does not reach the front midway, leaving a certain vertical strip in the middle without washing the front, the arm assembly 9,10 can be mounted The solution will be, for example, two opposing arms 9,10 which can be moved by the same belt 11.

The figures show the side brush solution of the washing machine, which is thus similar or mirror-image on the other side of the vehicle to be washed. The brush arrangement according to the invention may also be a unit for washing the roof of a vehicle.
