Definitions

  • the present invention relates to a surface treating machine according to the preamble of claim 1. Such a machine is shown in closest prior art reference WO 97/08984 .
  • the object of the present invention is to provide a novel surface treating machine of the type mentioned in the preamble.
  • the surface treating machine according to the invention is characterized in that at least a part of the pressure on the head is derived from the weight of the machine itself by way of the features of claim 1.
  • the pressure on the head is increased substantially and might be sufficient for all kinds of treatments of the surface.
  • Additional pressure means such as springs may be used to vary the pressure, if desired.
  • the head is pivotally connected to the frame which makes it easier to follow the descents and ramps in the surface, particularly if the head is positioned in front of the undercarriage.
  • the head is connected to a first arm of a two armed lever which is loaded by the weight of the machine, wherein the second arm of the lever is connected to the chassis, whereas a pivoting point of the lever is fixed to the frame of the machine.
  • the weight of the machine is distributed among the head and (a part of) the chassis.
  • the machine is partly supported by the head as a result of balancing the pivot point at the frame and depending on the length of both lever arms.
  • This system can freely move around the pivot point at the frame it follows descents and ramps in the surface while maintaining the pressure on the head.
  • the structure and dimensions of the lever can be chosen such that a desired pressure is exerted on the head, which remains more or less constant when the lever is pivoted within a limited range.
  • additional means such as springs or other loading means to vary the pressure on the head of the machine.
  • Fig. 1 is a very schematic sketch of a surface treating machine illustrating the principle of the present invention.
  • Fig. 2 is a schematic side view of a scrubber drier machine according to the present invention.
  • FIG. 1 show a surface treating machine, in this case a so called scrubber dryer machine used to clean large area floors in buildings. It should be understood that the invention can be used in all kinds of other machines for treating or maintaining surfaces.
  • the machine comprises a body or frame 1 and a chassis 2, 3 to enable the machine to move over a surface or floor S.
  • the chassis includes in this case one or two front wheels 2 and one or two rear wheels 3.
  • an operator is guiding the machine and is steering it through a handle or bar 4 ( Fig. 2 ), but the machine can also have a seat for a driver and drive means to move the machine.
  • the machine further comprises a head 5 including any kind of tool, in this case scrubber means 6 to act on the floor S.
  • the scrubber means 6 is rotatably driveable around an axis perpendicularly to the lower surface of the scrubber means 6.
  • a drive motor (not shown) is provided to rotate the scrubber means 6.
  • the head 5 is positioned in front of the front wheels 2 of the machine.
  • the head 5 is supported by the frame 1 in a manner so as to be freely moveable up and down in order to follow slopes and other irregularities in the surface S to be scrubbed.
  • first lever arm 8 of a two armed lever 7 In order to enable the head 5 to move, it is attached to the free end of a first lever arm 8 of a two armed lever 7.
  • This lever 7 is attached to the frame 1 through a pivot 10 which is positioned between the first lever arm 8 and a second lever arm 9.
  • These lever arms 8, 9 are positioned at an angle with respect to each other.
  • the free end of the second arm 9 is connected to an axle 11 of the front wheels 2 of the machine.
  • the weight at the front side of the machine is distributed among the front wheels 2 and the head 5, so that the head 5 is loaded downwardly against the floor and will exert a pressure on the scrubber means 6.
  • the amount of pressure on the scrubber means 6 is a result of the pressure exerted by the machine on the two armed lever 7 and the (horizontal) length ratio of the first and second arms 8, 9.
  • the design could be such that a desired pressure (i.e. 60 kg of weight) is exerted and it is also possible to provide some kind of adjustment to regulate the pressure, for example by shifting the pivot 10 along the lever, or adding further pressure by means such as adjustable and/or unadjustable springs or other means to apply force.
  • Some of the pressure on the head 5 will also be caused by the weight of the head 5, but at least a part of the weight of the head 5 is countered by the weight of the front axle and wheels 2, which are connected to the second lever arm 9 of the lever 7, i.e. on the other side of the pivot 10.
  • the head 5 is able to automatically follow a slope in the surface S by pivoting around the pivot 10 of the lever 7. Due to the rotation of lever 7, the front wheels 2 will be moved as well, but the wheels 2, 3 and the head 5 will always remain in contact with the surface S and the pressure on the head 5 will remain substantially constant, so that the efficiency of the machine will not be affected by slopes in the surface S.
  • the present invention provides a surface treating machine, the head of which is able to follow slopes in the surface while a substantially constant pressure on the head is maintained without any active regulation.
  • the machine is enabled to operate efficiently under all surface conditions on the one hand, whereas the machine is simple and robust on the other hand.
  • Lifting and lowering of the tool of the head can easily be done by moving the system consisting of wheels, levers and head around the pivot 10 at the frame by using mechanical or motorised means.
