Definitions

  • apparatus For scrubbing and for polishing of relatively large floor areas, frequent use is made of apparatus having a rotating member which is provided with a scrubbing or polishing material. Such apparatus exerts an angular momentum to one side on the floor or base, whereby the apparatus tends to deflect sideways from the desired path in a straight ahead direction, because of the reaction forces exerted by the base to the apparatus.
  • the object of the present invention is to provide a base processing apparatus with a varying means ensuring an optimum operation of the rotating member.
  • the present invention provides an apparatus for processing a base with the aid of a rotating member, such as for brushing or rubbing the floor, comprising:
  • the apparatus according to the present invention can be adapted by the varying means to the extent of the roughness of the base and the extent of roughness of the scrubber or polishing element.
  • the user can, as he/she wishes, bias the desired forward force and reduce or increase the angular momentum exerted by the rotating means.
  • the driving means may use fluid or gaseous medium.
  • the driving means comprise an electric motor and more preferably the apparatus is provided with a rechargeable battery so that wires can be dispensed with while the apparatus is in operation.
  • the apparatus preferably comprises two non-driven rear wheels.
  • the present invention is also of advantage for an apparatus with driven rear wheels, to prevent additional load on the bearings and/or gearing of one or more of the rear wheels.
  • the apparatus is provided with a central driven wheel, for reducing the pushing forces.
  • An apparatus 1 (fig. 1) comprises a chassis or frame 2, from which two non-driven rear wheels 3, 4 are suspended and a substantially horizontal wheel 5 or disk 6 which is driven in the direction of arrow A. To prevent the disk or wheel 5 damaging a wall W, the apparatus is preferably provided with a frame part 30 projecting beyond the circumference of the disk and on which a freely rotatable wheel 31 is disposed.
  • the wheel 5 or disk 6 exerts angular momentum relative to the pair of rear wheels in the direction of arrow A to the base, whereby the base exerts angular momentum in the opposite direction to the apparatus, which results in a tendency of a deflection to one side.
  • This can therefor be undesirable especially in the present embodiment where the rear wheels 3, 4 are not driven.
  • a pressing member 40 is disposed on frame 2, which obviates or reduces the angular momentum and converts it into a force in the forward direction of arrow B, which force also facilitates pushing the apparatus.
  • the position of the pressing force is adjustable relative to the disk, whereas the magnitude of the reaction angular momentum exerted by the base to the apparatus and the magnitude of the propelling force are also adjustable, If on e.g. a rough base or floor the pressing member is displaced in the direction of arrow D, the forward force is decreased, while the tearing to the side of the apparatus is reduced to a sufficient extent.
  • the forward force increases and the angular momentum of the base to the apparatus decreases.
  • Pulley 11 is disposed on a pivotable support part 13, and tension spring 14 maintain the tension in belt 12.
  • the apparatus is provided with a precharcheable battery, so that an electric cable can be dispensed with during the operation.
  • Wheel 5 and disk 6 are attached to the frame by means of a cardanic suspension 15 which is disposed on a suspension frame part 16, whereby wheel 5 and disk 6 are movable in all directions, at least in the pivot direction imposed by pressing member 40.
  • Pressing wheel 20 is pivotably disposed on a suspension part 22 via arm 21, which suspension part 22 is secured to the cardanic suspension 15.
  • the pressing force of the pressing wheel 20 can be varied by screwing of a counter weight 23 which is provided on a further arm 24 to pivot axis 25.
  • Pressing wheel 20 is in the present embodiment formed by a wear-resistant wheel of plastic material.
  • the position of the pressing wheel 20 is adjustable along the circle arc of arrows C and D by means of an adjusting knob 26 which can be arrested e.g. in a depressed rest position, and which will displace a toothed rack 28, according to the circle arc through toothed pinion 27, when it is lifted and turned.
  • an adjusting knob 26 which can be arrested e.g. in a depressed rest position, and which will displace a toothed rack 28, according to the circle arc through toothed pinion 27, when it is lifted and turned.
  • the user will primarily adjust the position of the pressing wheel of the disk dependent on the roughness/smoothness of the surface to be scrubbed or polished and dependent on the type of scrub element or polishing element present under the disc, as this biasing can be executed easily from the exterior. Since biasing the magnitude of the pressing force will have to be done in the interior of the apparatus e.g. by screwing and displacing of the counter weight, this type of adjustment is less preferred in actual practice.
  • the apparatus is preferably provided with a central driven wheel for driving the apparatus. It goes without saying that the present invention is not limited to the above described preferred embodiment thereof. The requested rights are primarily defined by the following claims, within the scope of which various modifications are possible.
  • a variation which is not limited, relates e.g. to the way in which the force exerted by the pressing wheel to the disc is adjusted. As shown in figure 3, this force can also be adjusted through a screw spring 51 which can be adjusted by turning knob 52.
